The Unnamed Wife in Sir Gawain and the Green Knight Essay

The Unnamed Wife in Sir Gawain and the Green Knight In Sir Gawain and the Green Knight the green knight’s wife plays a pivotal role in the story. Yet, she is never given a name and it is unclear what motivates her actions. She could simply be following her husband’s orders to seduce this visiting knight. She could be under the tutelage of Morgan le Fay. Or she may be acting under her own guidance and using her sexuality to carry out her own desires or gain power. In light of this uncertainty, the unnamed wife’s role in the bedroom scene is also hard to decipher. As a woman she should be submissive, and yet it is Gawain who is forced to defend himself against her advances to which he eventually submits. The multiple readings of†¦show more content†¦She also refers to Gawain as, â€Å"my captive knight†. This suggests that Gawain is in the submissive position, which is not typically how a powerful, male knight is perceived. Oddly enough, this is the case in medieval society. The lord is the master and the knight pledges loyalty to the lord and his lady. In this sense the knight is actually in a lower social position than the lady, and this problemitizes the typical gender roles. For instance, Gawain must tell the wife, â€Å"I am yours to command, to kiss when you please† in order to live up to the expectations of a courteous knight. His social role as a knight causes him to submit to this cunning woman. The lady is able to exert control over Gawain while still appearing submissive, because of Gawain’s conflicting social and gender roles. However, the gender roles and power relations between the wife and Gawain are further complicated when considering the wife’s loyalty to her husband. If she is merely following his orders and offering her body to whom ever he commands, then she is undoubtedly submissive. Clearly the wife’s actions are in line with her husband’s plans. In the end he tells Gawain, â€Å"And the wooing of my wife—it was all my scheme!† Despite this fact, it is uncertain wheatear the wife is forced to joinShow MoreRelated Essay on Games in Sir Gawain and the Green Knight1328 Words   |  6 PagesGames in Sir Gawain and the Green Knight   Ã‚  Ã‚   Many games are involved in the plot of Sir Gawain and the Green Knight.

Essay on The Duel Between Aaron Burr and Alexander Hamilton

In the battle between Aaron Burr and Alexander Hamilton was one of the most famous duels in the early 19th century. Both men were very significant political leaders of the United States. The men had clashes throughout the 1790’s which lead to a duel between the two and Alexander Hamilton lost his life. Aaron Burr was born in New Jersey in 1756. He was involved in many political events though out his life. He was the second president of Princeton, and he was the grandson of Jonathon Edwards. This man had politics woven all through him. While at the college of New Jersey, which later became Princeton, Burr was studying theology, but he quickly switched his degree to law.

In this era, being outstanding in Washington’s eye was substantially magnificent. Hamilton married a young lady by the name of Elizabe th Schuyler; she was the daughter of a general. This put Alexander Hamilton in the middle of New York’s politics. In 1782, Hamilton was elected to the Continental Congress. As Alexander Hamilton’s political career began to get under way, things seem to be going as planned. He played a major role in the constitution. He was one of Americas first Constitutional lawyers, and wrote most of the Federalist Papers, a primary source for Constitutional interpretation. He was perhaps the best lawyer in America at the time of his death and his views were remarkably consistent and coherent. He also had a clear vision of the new nation and believed that it could learn much from British economic policy and governmental practice. Since he played such a major role in the Constitution Convention, he obviously was going to serve a major role in the new government. He proved himself a brilliant administrator both in organizing the Treasury Department and in assisting generally to set guidelines for and staff all the departments of government. He proposed, to pay the nations debts in full and also to assume the unpaid debts of the various states.

Antiphishing Free Essays

Name: B. sreevidya Rno: 08491D5804 FINDIND amp; STOPING OF PHISHING ATTACKS THROUGH ONLINE ABSTRACT: Phishing is a new type of network attack where the attacker creates accurate copy of an existing web page to fool users ex submitting personal, financial, or password data to what they think is their service provider’s website. The concept is an anti-phishing algorithm, called the Link Guard, by utilizing the generic characteristics of the hyperlinks in phishing attacks. We will write a custom essay sample on Antiphishing or any similar topic only for you Order Now The link Guard algorithm is the concept for finding the phishing emails sent by the phisher to grasp the information of the end user. Link Guard is based on the careful analysis of the characteristics of phishing hyperlinks. Each end user is implemented with Link Guard algorithm. Existing System: 1) Detect and block the phishing Web sites in time: If we can detect the phishing Web sites in time, we then can block the sites and prevent phishing attacks. But it’s difficult to find those phishing sites out in time. There are two methods for phishing site detection. a) The Web master of a legal Web site periodically scans the root DNS for suspicious sites. ) Since the phisher must duplicate the content of the target site, he must use tools to (automatically) download the Web pages from the target site. It is therefore possible to detect this kind of download at the Web server and trace back to the phisher. Drawbacks:-Many phishing attacks simply do not require a DNS name. For phishing download detection, clever phishers may easily write tools 2) Enhance the security of the web sites: The business Websites such a s the Web sites of banks can take new methods to guarantee the security of users’ personal information. There two method to enhance the security a) Using hardware devices: For example, a hand-held card reader b)Biometrics characteristic: e. g. voice, fingerprint, iris, etc. Drawbacks:-All these techniques need additional hardware and also will increase the cost. Therefore, it still needs time for these techniques to be widely adopted. Block the phishing e-mails by various spam filters: The phishers hide their identities when sending the spoofed e-mails, therefore, if anti-spam systems can determine whether an e-mail is sent by the announced sender the phishing attacks will be decreased dramatically. The techniques that preventing senders from counterfeiting their Send ID (e. g. SIDF of Microsoft) can defeat phishing attacks efficiently. SIDF is a combination of Microsoft’s Caller ID for E-mail and the SPF (Sender Policy Framework). Both Caller ID and SPF check e-mail sender’s domain name to verify if the e-mail is sent from a server that is authorized to send e-mails of that domain and from that to determine whether that e-mail use spoofed e-mail address. If it’s faked, the Internet service provider can then determine that e-mail is a spam e-mail. The spoofed e-mails used by phishers are one type of spam e-mails. the spam filters can also be used to filter those phishing e-mails. Spam filters are designed for general spam e-mails and may not very suitable for filtering phishing e-mails since they generally do not consider the specific characteristics of phishing attacks. 4) Install online anti-phishing software in user’s computers: Despite all the above efforts, it is still possible for the users to visit the spoofed Web sites. As a last defense, users can install anti-phishing tools in their computers. The anti-phishing tools in use today can be divided into two categories: blacklist/white list based and rule-based. a) When a user visits a Web site, the antiphishing tool searches the address of that site in a blacklist stored in the database. If the visited site is on the list, the anti-phishing tool then warns the users . They cannot prevent the attacks from the newly emerged (unknown) phishing sites. b) Uses certain rules in their software, and checks the security of a Web site according to these rules. Examples Spoof Guard and Trust Watch provide a toolbar in the browsers all the above defense methods are useful and complementary to each other, but none of them are perfect at the current stage. PROPOSED SYSTEM A. Classification of the hyperlinks in the phishing e-mails The hyperlinks used in the phishing e-mail into the following categories: 1) The hyperlink provides DNS domain names in the anchor text, but the destination DNS name in the visible link doesn’t match that in the actual link. For instance, the following hyperlink: lt;a href= â€Å"http://www. profusenet. et/checksession. php†gt;https://secure. regionset. com/EBanking/logon/ lt;/agt; appears to be linked to secure. regionset. com, which is the portal of a bank, but it actually is linked to a phishing site www. profusenet. net. 2) Dotted decimal IP address is used directly in the URI or the anchor text instead of DNS name. For example. lt;a href= â€Å"http://61. 129. 33. 105/secured-site/www. skyfi. Com/ index. html? MfclSAPICommand=SignInFPPamp;UsingSSL= 1†³gt; SIGN IN lt;/agt; 3) The hyperlink is counterfeited maliciously by using certain encoding schemes. There are two cases: a) The link is formed by encoding alphabets into their corresponding ASCII codes. See below for such a hyperlink. lt;a href=†http://034%02E%0333%34%2E%311%39%355%2E%o340o31:%34%39%30%33/%6C/%69%6E%64%65%78%2E%68%74%6D†gt; www. citibank. com lt;/agt; While this link is seemed pointed www. citibank. com, it actually points to http://4. 34. 195. 41:34/l/index. htm. b) Special characters (e. g. (in the visible link) are used to fool the user to believe that the e-mail is from a trusted sender. For instance, the following link seems is linked to amazons, but it actually is linked to IP address 69. 10. 142. 34. http://www. amazon. com:fvthsgbljhfcs83infoupdate@69. 10. 142. 34. 4) The hyperlink does not provide destination information in its anchor text and uses DNS names in its URI. The DNS name in the URI usually is similar with a famous company or organization. For instance, the following link seems to be sent from PayPal, but it actually is not. Since paypal-cgi is actually registered by the phisher to let the users believe that it has something to do with paypal lt;a href= â€Å"http://www. aypal-cgi. us/webscr. php? Cmd=Login†gt; Click here to confirm your account lt;/agt; 5) The attackers utilize the vulnerabilities of the target Web site to redirect users to their phishing sites or to launch CSS (cross site scripting) attacks. For example, the following link lt;a href=†http://usa. visa. com/track/dyredirjsp? rDirl=http://200. 251. 251. 10/. verified/†gt; Click here lt;agt; Once clicked, will redirect the user to the phishing site 200. 251. 251. 10 due to a vulnerability of usa. visa. com. B. LINK GUARD ALGORITHM: LinkGuard works by analyzing the differences between the visual link and the actual link. It also calculates the similarities of a URI with a known trusted site C. LINK GUARD IMPLEMENTED CLIENT: It includes two parts: a whook. dll dynamic library and a LinkGuard executive. Whook is a dynamic link library; it is dynamically loaded into the address spaces of the executing processes by the operating system. Whook is responsible for collecting data, such as the called links and visual links, the user input URLs. LinkGuard is the key component of the implementation. It’s composed of 5 parts Comm: This collects the information of the input process, and sends these related information’s to the Analyzer. Database: Store the white list, blacklist, and the user input URLs. Analyzer: It is the key component of Link Guard, which implements the Link Guard algorithm; it uses data provided by Comm and Database, and sends the results to the Alert and Logger modules. Alerter: When receiving a warning message from Analyzer, it shows the related information to alert the users and send back the reactions of the user back to the Analyzer. Logger: Archive the history information, such as user events, alert information, for future use.

Group Contribution Research and Presentaion on Oral Health

Question: Discuss about the Reflection on group contribution Research and Presentaion on Oral Health. Answer: In recent past week, we had a project as a group of four. The title of our project was say yes to fluoride water. Our main aim was to create awareness to the Cairns population about the importance of oral health. In addition to the awareness, we also aimed at enlightening the population about the important benefits of the fluoride water to oral health. Fluoride water has great benefits on our teeth (Clarkson, and McLoughlin, 2000). We realize that few people understand the benefits of fluoride water in our oral health. Thus, to start with, we chose the Cairns population. Each of the group members had a part to play in the project. Besides, we all came up with different ideas and sharing the responsibilities of presentation. We held several discussions to brainstorm the ideas of our presentation, which gave us a chance to incorporate new ideas and even alter what seemed not necessary. The necessary arrangements for the project were also made through meetings where members gave their s uggestions. My main part of the project was dealing with the introduction part. This is one of the critical parts of any report or task. However, the group members had total confidence in me due to my good understanding of presentation skills. Hence, they thought it was necessary for me to start and set the stage for the rest of the group members. Working in a group is effective and mind provoking (Haddock, 1997). At first, the feeling was scary as I saw as though the responsibility was too much for me, but then I wanted to learn as much as I could. I had to take up the challenge. To begin with, I had to organize my work since we had already finalized everything. My main tasks included determining the target population, geographical region, gender, and those at risk. The presentation had to be the best, and I strived to ensure that the introduction was appealing to the target group. It was my responsibility to seek extra information, which I thought that maybe the group had not provided. At last , the project was a success, and my part was well done. Developing such health promotion activity with a team made it seem simple. Generating ideas was one of the easiest things. However, I cannot assume the fact that at some level we could not easily reach a consensus on some ideas. As a group, we would be forced to do some in-depth research and come up with the results later on during the next meeting. This gave us a good chance to learn various intriguing things concerning the importance of health promotion activity and doing it as a team. Besides that, working as a team one understands the importance of adjusting to situations and making good decisions (Parahoo, 2014). It was during the development of the project when one of our members withdrew from the team. At this point, we had shared the responsibilities, and since the responsibility given to her was as important as anybody elses in the group, we had to find a way of incorporating it with our individual responsibilities. Working as a team made it easier to conduct research since responsibilities were shared (Rootman, 2001). Besides, the ideas from the members benefited the group a lot. Unlike working alone in a project where you tend to believe all your opinions, working in a group was different. At some point, your opinion that you believed to be the best is refuted and replaced with a better idea. It is this aspect that I learned so much about principles and practices of health promotion. After successfully completing the project, I felt as though I have learned something great. Conducting research was something new for me, but the project exposed me. Besides, for the first time, I got a chance to work on something great with a group. As the leader of the team, coordinating the group was not an easy task (Resnicow et al. 2002). Now I fully understand how to accommodate people with different opinions as well as acting as a moderator. Making presentation is one of my favorite activities but presenting such project instilled a new feeling in me. My expectations as from now are to be involved in projects that are more similar. I would wish to put into use my little understanding and explore other skills that come along with experience. On a similar note, I would wish to work with a team of self-motivated individuals like the previous one. Teamwork seems to provoke someones mind through a new understanding of some issues unlike working individually (Driscoll, 1994). As per now I am knowledgeable than before and expects to make good use of my knowledge by sharing with others. Bibliography Clarkson, J.J., and McLoughlin, J., 2000.

Collective Bargaining Essay Example | Topics and Well Written Essays - 2000 words

Collective Bargaining - Essay Example The unionization law, therefore, differs in various economic systems. The unionization is not allowed directly but it is a method that is developed in order to exercise collective bargaining and in its objective forming unions is a legal act (Katz, 1993). The formation of a union is only acceptable in private sector but it is treated as a capital crime in governmental offices and armed forces. In case of armed forces, the culprits of unionization are thrown into jail and upon completion of their sentence, they are court-martialed. The formation of a union is the last thing a soldier will think about before leaving his or her job. Additionally, armed forces argue that they are operating for saving their nations’ sovereignty and pride and therefore, they should not indulge in providing ideal work environment for the soldiers while they have to live in tough environment during the war so they must be trained in terms of making the most of even the worst kind of work climate. The practices of collective bargaining and unionization are known to emerge at the end of the great depression when people were forced to work in the extremities of inhumane environments. With the passage of time, the workers started to raise voices about their work environment and finally, legal courts initiated to respond to their needs and companies had to offer their employees a safe and sound environment to work in. the stream of change in this regard because the beacon of moment shifted towards improving the quality of supervisory behaviors as time passed. The legal pressures caused the companies to adopt modern philosophies of management such as delegation of authority and participative management. The Japanese taught the world that bureaucracy is an inefficient way of managing the organizations because it wastes too much time in decision making and they presented the concept of self-managed teams which scanned the environment so that they can develop strategies in order to cope with the current challenges of the business.

Cambodian Genocide Essay Example | Topics and Well Written Essays - 1250 words

Cambodian Genocide - Essay Example This genocide had a devastating effect to the people of Cambodia. An estimated 25% of the total population was killed. In addition, property worth billions was destroyed. Moreover, this genocide brought unprecedented suffering to the people of Cambodia. This caused psychological trauma to those who survived it. Mass graves were discovered later and the unearthed bones are preserved in memory of those who died in the genocide. In this paper, I will focus on Pol Pot’s ideology leading him to reconstruct Cambodia as well as the extermination of all those who were a formal threat to his success in achieving his mission. History of Cambodia before Genocide Cambodia, an Asian country, gained independence in the year 1953 after being ruled by the French for more than 100 years (Moses 224). It is famous due to its temples back in the 12th century. After independence, in the 1960s, Cambodia had a population of around 7 million people. 95% of the total population belonged to Buddhism re ligion. At this time, the country was under the rule of Prince Sihanouk. He continued to rule the country until 1970 when he was ousted from power through a military coup. Lon Nol, who was a lieutenant general came to power and was made the president. In retaliation, Prince Sihanouk joined his army with that of Khmer Rouge and started attacking Lon Nol’s army. ... Cambodia then became a battlefield. On the other hand, Pol Pot led Khmer Rouge, the guerrilla organization. Pol Pot was born in 1925 in central Cambodia. By that time, Cambodia was part of France (Bergin 9). When still young in his early 20s, Pol went to Paris, France where he pursued his education. He never cleared his studies as he joined Marxism and lost his scholarship. Pol Pot envied the Chinese communism. In 1962, Pol pot was leading the Cambodian Communist Party. Prince Sihanouk was not happy with Pol Pot affiliation. Pol Pot had to flee from Prince Sihanouk; he went to the jungle. In the jungle, Khmer Rouge, an armed movement headed by Pol Pot, was created. He defeated Prince Sihanouk in 1976 and he became the premier. Pol Pot believed that farmers were the best people in the world. He particularly admired the Chinese communism, and he believed in it. He tried to introduce this to his country, and he treated those who opposed him with brutality (Munyas 427). In fact, he belie ved that the more he killed the better since he was helping to purify the country. Khmer Rouge was the tool that Pol Pot used to rule Cambodia by an iron fist. The army was used to enforce his policies. Cambodia During he Genocide After successfully overthrowing the government, the Khmer group developed a mission for the country (Maguire 44). It wanted to incorporate the Mao, a Chinese communism model. Its approach was extreme and according to the group, it was the ideal way for the country to move on. Pol Pot and his group did not give a chance to the Cambodians to choose what they wanted. Instead, the population was forced to work on large farms. The group was ruthless with anyone who tried to go against it. All un-communists were

MarketingProject-Kuwait - Research Paper Example Additionally, the low average utilization of aircrafts, gives them a higher cost per every seat mile, this is different from Jazeera Air, which has cut its fleet and uses its aircrafts extensively (Shaw 35). This paper discusses how Ryanair’s limited airport transportation will work in the Middle East where the airports are concentrated. Consumers across the globe have continued to turn towards the internet for their various travel needs. This involves research on trips, comparison of prices, shopping for flights and booking. Consumers have found this convenient and vital to their business and personal travel needs. Looking across the markets with increased focus on the Middle East market, there are various emerging demographic trends that drive growth across the B2C travel industry. Understanding this trend is vital for Ryanair in order to create a strong presence online and increase market share. One demographic group, which would fly Ryanair is the age group from twenty fiv e to thirty four. This is because these are the most likely to prefer low cost carriers, as they have just started earning and would be more willing to forfeit the comfort and luxury of a traditional airline for the cost saving measures of a low cost carrier like Ryanair. People from thirty five to forty four would also consider flying Ryanair because of its cost cutting. This is generated by the idea that they have most likely had increased responsibilities. However, it should be noted that these are those people in the middle to low income earning bracket. Those over sixty-five were the least willing to consider flying Ryanair. Another demographic, which would fly Ryanair would be students studying abroad or travelling for study trips. This would be informed by the fact that they will be doing this on funds from the government or school. However, there was a disparity with the sexes, with one woman claiming that low cost carriers did not provide enough segregation for women, and s ince she preferred to remove her booking on the flight, she would be uncomfortable. Another demographic that would most certainly be willing to fly Ryanair for its low cost measures is tourist groups. Given that most claimed to be travelling on a budget that they had been saving for a while. For business people, the most receptive to Ryanair travel were those in supervisory roles or junior management positions, in their companies. Those in middle management roles were also receptive of the idea of a low cost carrier. However, those in professional roles or senior management are least interested in a low cost carrier like Ryanair. Finally, Kuwaiti’s travelling to Europe to experience leisure or visit relatives and friends are likely to fly Ryanair for its low cost. However, business people were least interested in using a low cost carrier like Ryanair, despite the fact that it would save their organization money. Clients who are concerned about the environment could elect to f ly low cost carriers since the reduced weight of the plane leads to a reduction in fuel used by the plane (Shaw 38). These airlines also offer a fairly simpler scheme for fares, for example, charging tickets for one way at half the price of round trips. This encourages clients to choose it. Since these carriers fly to less congested and smaller secondary airports during off-peak hours to avoid delays by traffic, they offer an

Classification According To Maturity Biology Essay

Classification According To Maturity Biology Essay INTRODUCTION The human eye is very nearly spherical, with a diameter of approximately 24 mm (nearly one inch). It consists of three concentric layers, each with its own characteristic appearance, structure and functions. From outermost to innermost, the three layers are the sclera, which protects the eyeball; the choroid, which nourishes the eyeball; and the retina, which detects light and initiates neural messages bound for the brain. The eye is partitioned into two chambers, a small anterior chamber and a larger vitreous chamber. Thus the basic layout consists of three concentric layers, two chambers, iris, pupil and the lens (Ross and wilson, 2001). Fig.1 Anatomy of the eye C:UsersDHINESHDesktopUntitled1.png The Lens One of very important optical element of the eye, the crystalline lens, lies right behind the iris. The lens takes its name from its resemblance to a lentil, or bean. In adults, the lens is shaped about 9 mm in diameter and 4 mm in thickness. The lens consists of three distinct parts: an elastic covering, or capsule; an epithelial layer just inside the capsule; and the lens itself. The thin, elastic capsule around the lens has two jobs. First, it moderates the flow of aqueous humor into the lens, helping the lens retain its transparency to light. Second, the elastic capsule moulds the shape of the lens varying its flatness and, thereby, the lens optical power. This variant in optical power is called accommodation. Lens grows throughout the life span; the outer, epithelial layer of lens continues to produce protein fibres that are added to the surface of the lens. Consequently, those protein fibres nearest the centre of the lens are the oldest (some were present at birth), whereas the fibres on the outside are the youngest. Between birth and 90 years of age, the lens quadruples in thickness and attains a weight of 250 mg. In the centre of the lens, the old fibres become more densely packed, producing sclerosis, or hardening, of the lens (Paterson, 1979). For good vision, the lens must be transparent and light must be able to pass through it easily, without loss or deviation. Like the cornea, this transparency depends on the material out of which the lens is made. Of all the bodys parts, the lens has the highest percentage of protein, and its protein fibres are lined up parallel to one another, maximizing the lens transparency to light. Anything that disturbs this alignment such as excess fluid inside the lens reduces its transparency. An opacity (or reduced transparency) of the lens is called a cataract. While some cataracts are minor, barely reducing the transmission of light, others undermine vision to the extent of blindness (Kyselova, 2004). Cataract Cataract is the opacification and crystalline formation of eye lens, associated with the breakdown of the eye lens micro-architecture, which interferes with the transmission of light onto the retina. Several biochemical processes for example, calcium deposition, oxidative stress, phase transition, altered epithelial metabolism, crystalline precipitation, calpain-induced proteolysis and cytoskeletal loss takes place during the development of cataract (Moghaddam, 2005). Fig.2 Normal, clear lens Fig.3 Lens clouded by cataract C:UsersDHINESHDesktopUntitled.png Fig.4 Etiology of cataract (Jacob, 1999) C:UsersDHINESHDesktopUntitled.png TYPES OF CATARACT A. Acquired cataract 1. Age related cataract a) Morphological classification i) Subcapsular cataract Anterior subcapsular cataract mainly associated with fibrous metaplasia of the epithelium present below the lens capsule. Posterior subcapsular cataract lies just in front of the posterior capsule and a clear vacuolated, granular or plaque-like appearance. Near vision is also most often impaired more than distant vision. ii) Nuclear cataract usually begins as an amplification of the changes most often seen with normal aging lens nucleus. It is often related with increased spherical aberration and also with an increased refractive index leading to myopia. Some elderly patients may consequently be capable to read yet again without spectacles. iii) Cortical cataract may be associated with the anterior, posterior or equatorial cortex. The opacities begin as clefts and vacuoles between lens fibres because of hydration of the cortex. Both cortical and subcapsular cataracts are white on oblique illumination and show black colouration, silhouetted against the red reflex, on retroillumination. b) Classification according to maturity i) An immature cataract means partially opaque lens. ii) A mature cataract means completely opaque lens. iii) A hypermature cataract means the leakage of water from the lens it leads to wrinkled and shrunken anterior capsule. iv) A morgagnian cataract means the total liquefication of lens cortex like hypermature cataract and it allows the lens nucleus to shrink inferiorly (Hejtmancik, 2004). 2. Presenile cataract Cataract may develop early in the following conditions, a) Diabetes mellitus Typically diabetic cataract is rare. In hyperglycemic conditions, the aqueous humor secretes high level of glucose and this excess of glucose diffuses into the lens. Aldosereductase metabolises glucose to sorbitol, which then accumulates in the lens, resulting in secondary osmotic over hydration of the lens substance. Nuclear opacities are common and tend to grow rapidly. Premature dystrophy may be seen due to decreased pliability of the lens. b) Myotonic dystrophy About 90% of patients, in third decade have fine cortical iridescent opacities, which evolve into visually disabling stellate posterior subcapsular cataract by the fifth decade. c) Atopic dertmatitis About 10% of patients with severe atopic dermatitis develop cataracts in the second to fourth decades. The opacities are often bilateral and may mature quickly. Shield like anterior subcapsular plaque which wrinkles the anterior capsule is characteristic. Posterior subcapsular opacities resembling a complicated cataract may also occur. 3. Traumatic cataract Trauma is the major risk factor for unilateral cataract in individuals. The following risk factors are involved in traumatic cataract, a) Direct penetrating injury to the lens. b) Concussion may cause an imprinting of iris colour on the anterior lens capsule (Vossius ring) as flower shaped cortical opacities (rosette cataract). c) Electric shock and lightening are rare causes. d) Ionizing radiation. e) Infrared radiation- In glassblowers, the IR rays causes exfoliation of the lens capsule which results in thickening of the superficial portion of the capsule and it further splits the deeper layer and protrudes into the anterior chamber. B. Drug induced cataract a) Steroidal drugs may induce cataract. Initially the lens opacities formed in posterior subcapsular region spreads into the anterior region. The relation between dose, duration of administration and the cataract development is unclear. It is understood that children may be more at risk to the cataractogenic effects of systemic steroids and genetic susceptibility may also be of significance. Patients who develop lens physiological changes should have their dose decreased to a minimum, reliable with control of the underlying disease, and if feasible be considered for alternate drug therapy. Premature opacities may regress if therapy is discontinued, alternatively progression may occur despite withdrawn and warrant surgical intervention. b) Chlorpromazine may cause the deposit of innocuous fine, stellate, yellowish brown granules on the anterior lens capsule within the papillary area. The deposition of granular material may accumulate on the corneal endothelium and deep stroma. Both lenticular and corneal deposits are dose -related and irreversible. In very high doses (>2400 mg daily), this drug may cause retinotoxicity. c) Lens opacities may occur due to the irregular use of Busulphan (Myleran) for the treatment of chronic myeloid leukaemia. d) Amiodarone, used in the treatment of cardiac arrhythmias, causes visually inconsequential anterior subcapsular lens deposits in about 50% of patients on moderate to high doses. e) Gold used in the treatment of rheumatoid arthritis, causes harmless anterior capsular deposits in about 50% of patients on treatment for more than 3 years. f) Allopurinol, used in the treatment of hyperuricaemia and chronic gout, increases the risk of cataract formation in elderly patients, if the cumulative does exceeds 400 g or duration of administration exceeds 3 years. C. Secondary cataract A secondary (complicated) cataract grows as a result of some other primary ocular diseases. i. Chronic anterior uveitis is the main cause of secondary cataract. The earliest finding is a polychromatic lustre at the posterior pole of the lens which may not progress if the uveitis is arrested. If the inflammation persists, posterior and anterior opacities developed may progress to maturity. ii. Acute congestive angle closure glaucoma may cause small grey white anterior, subcapsular or capsular opacities within the papillary area. a. Myopia (Pathological) is linked with posterior subcapsular lens opacities and early-onset nuclear sclerosis, which may ironically increase the myopic refractive error. Simple myopia, however, is not associated with such cataract formation. b. Hereditary dystrophies such as retinitis pigmentosa, gyrate atrophy, leper congenital amaurosis and stickler syndrome may be associated with posterior subcapsular lens opacities. Cataract surgery may occasionally improve visual acuity even in the presence of severe retinal changes (Kanski et al., 2003). Free radicals involved in cataractogenesis Free radicals may be formed either by the reduction of molecules by electron transfer or by the haemolytic cleavage of covalent bond. Both these reactions may be enzymatic or non-enzymatic. Due to the presence of an odd unpaired electron in its outermost orbital, these free radicals are unstable and readily react with neighbourhood molecules and extract electrons from them, converting the attacked molecule into a few radical, which in turn attacks another molecule generating more free radicals and so on. This enables free radicals to induce chain reactions that may be thousands of events long. A free radical reaction is terminated by reaction between two free radicals or neutralization by antioxidants (Uday et al., 1999). Fig.5 Pathways of ROS formation C:UsersDHINESHDesktopUntitled 3.png Generation of free radicals Biological free radicals include reactive oxygen species, reactive nitrogen species, reactive sulphur species, free radicals obtained form xenobiotics. a) Superoxide anion radical (O2.-) It is generated from NADPH oxidase and from mitochondria. i) NADPH oxidase is present in the lysosomal cell membranes. It steals electron from O2 resulting in the formation superoxide anion radical (O ·2-). It is converted to hydrogen peroxide and is a spontaneous reaction which is known as respiratory burst. This hydrogen peroxide may react with the chlorine in the presence of myeloperoxidase to form hypochlorous acid or it may produce hydroxyl radicals, by the Fenton reaction which uses the metal ion Fe3+. ii) From Mitochondria: Ubiquionone, which is a terminal acceptor of electron, is converted to semiquinone (free radical). By reacting with O2, it forms (O ·2-) super oxide radical with H2O2, it produce hydroxyl radical ion. b) Hydrogen Peroxide H2O2 SOD It is formed by the dismutation of superoxide by the enzyme superoxide dismutase. O · 2 + O ·2 Hydrogen peroxide is generated from i) Aminoacid oxidases: Flavin is a co-enzyme required for the oxidative deamination of amino acid. The reduced flavin attacks molecular oxygen to form hydrogen peroxide. ii) Xanthine oxidase: Xanthine oxidase catalyses the conversion of hypoxanthine to xanthine and hydrogen peroxide is released from molecular oxygen. iii) Peroxisomes: Peroxisomes is the site of  Ã‚ ¢-oxidation of fatty acids.  Ã‚ ¢- Oxidation of the fatty acids is catalysed by acetyl co-enzyme-A dehydrogenase. During this process, a co-enzyme called FAD which donates two electrons gets reduced to FADH2. Again it is converted to FAD. During that process it gives out O2 and H2O (Kovaceva et al., 2007). c) Hydroperoxyl radical They are highly lipophillic and capable of initiating lipid peroxidation. Lipid peroxidation Lipid peroxidation is a self- perpetuating common process and involves the conversion of lipid components from cell organelles into lipid peroxides resulting in the formation of a pigment known as lipofuscin. Lysosomic reactive oxygen species are formed as a result of complex oxidative chain reactions in mitochondria during energy production. H2O2 formed in smaller amounts by mitochondria pass through walls of lysosome and react with Fe (II) in a reaction known as Fenton reaction to form potent hydroxyl radicals which cause lipid peroxidation (Halliwell, 2001). Malondialdehyde is the major reactive aldehyde resulting from the peroxidation of biological membrane polyunsaturated fatty acids (PUFA). MDA, a secondary product of LPO, is used as an indicator of tissue damage by a series of chain reactions. MDA is a by-product of prostaglandin biosynthesis. It reacts with thiobarbituric acid and produces a red-coloured product. MDA is a mutagenic and genotoxic agent that may contribute to d evelopment of human cancer. Ca2+ ATPase The Ca2+ ATPase is a transport protein in the cells that serves to eliminate calcium (Ca2+) from the cell. It is essential for maintaining the amount of Ca2+ within the cells. Based upon the electrochemical gradient calcium ion enter into the cells through the trans membrane. This process is important for the cell signalling by which it lowers calcium level. Thus it is necessary for the cell to utilize ion pumps to remove the Ca2+. The Ca2+ ATPase is expressed in a variety of tissues, together with the brain (Hightower et al., 1982). IN VIVO MODELS IN CATARACT (Gupta, 2004) 1. Sugar cataract i) Galactose induced cataract The changes associated with galactose cataractogenesis include the initial reduction of galactose into dulcitol through intervention of aldose reductase with NADPH as a co-factor. Accumulation of dulcitol in the lens, (since it is not metabolized) creates cellular hypertonicity associated with and/or followed by a cascade of events, which includes an influx of water, swelling of the lens fibres, epithelial cell edema, damage of plasma membrane, compromise of cellular permeability, a drop in myinositol level, a reduction in Na+ K+ ATPase activity an influx of Na+ and Cl- and an efflux of K+ and the loss of glutathione and aminoacids. These are the morphological, biochemical, enzymatic and molecular alterations in the lens associated with galactose cataracts. ii) Alloxan induced cataract Alloxan is a cyclic urea analog which is highly reactive molecule that is readily reduced to dialuric acid, which is then auto oxidized back to alloxan resulting in the formation of hydroxyl radical, O2.-, including H2O2 (hydrogen peroxide). However, the other mechanism reveals the ability of alloxan to react with protein sulfhydryl groups on hexokinase, a signal recognition enzyme in the pancreatic ÃŽ ²-cells that couples changes in the blood glucose concentration to the rate of insulin secretion. By this mechanism, inhibition of glucokinase and other SH containing membrane proteins on the ÃŽ ²-cells would eventually result in cell necrosis within minutes. iii) Streptozocin induced cataract Diabetes related cataractogenic changes are seen in the animals injected with streptozocin. This streptozocin initiates cytotoxic action in pancreatic ÃŽ ² cells because sreptozocin contain glucose molecule and highly reactive nitrosourea side chain. It binds to the membrane receptor to generate structural damage. At the intracellular level three major phenomena are responsible for ÃŽ ² cell death, i) Methylation ii) Free radical production iii) Formation of Nitric oxide (NO). The damage caused to ÃŽ ² cells alters the sugar metabolism leading to diabetes. 2. Selenite induced cataract Selenite cataract resembles human cataract in many ways such as insoluble protein, vesicle formation, increased calcium, reduced glutathione (GSH) and decreased water-soluble proteins. However, selenite cataract shows no high molecular weight protein aggregation or increased disulfide formation and is dominated by rapid calpain-induced proteolytic precipitation, while senile cataracts may be produced by prolonged oxidative stress. 3. Naphthalene induced cataract Naphthalene is oxidized in the liver initially to an epoxide and then it converted into naphthalene dihydrodiol. This stable component is converted enzymatically into dihydroxynaphthalene to reaching the eye. Being unstable at physiological pH, 1, 2- dihydroxynaphthalene and spontaneously autooxidises to 1, 2- naphthoquinone and H2O2 . It alkylates proteins, glutathione and aminoacids and generates free radicals. 4. Glucocorticoid induced cataract Glucocorticoid cataract results in the formation of steroid- adduct protein, induction of transglutaminase and reduction of ATPase activity may lead to cataract. Steroid cataracts are produced by the activities of glucocorthicoids and progressed by way of production of oxidative stress similar to other types of cataract. 5. L- Buthionine S, R- Sulfoximine (BSO) induced cataract Glutathione is present in mammalian lens in high concentrations and is involved in the protection of lens against oxidation. In most of the cataracts the decrease in its level is observed. 6. Smoke induced cataract Cigarette smoke contains trace and heavy metals. The increased metal contents in lens cause lens damage by the mechanism of oxidative stress-forming oxygen radicals, via metal catalyzed Fenton Reaction. In other words cigarette smoke is associated with the accumulation of iron and calcium. 7. UV radiation induced cataract Epidemiological studies have exposed a link between exposure to UV radiation in sunlight and development of cataract. Experimental studies confirm that ultraviolet (UV) radiation induces cataract. There is, however, a lack of data on the age dependence in experimental UV radiation-induced cataract. 8. Microwave induced cataract Microwave radiation has been reported to produce posterior subcapsular and cortical cataracts in rabbits and dogs within a short span of time. 9. Transforming Growth Factor ÃŽ ² (TNFB) induced cataract TGFB is induced by injecting approximately 60 ng TGFB into the vitreous. TGFB induce lens epithelial cells to undergo molecular modify and abnormal morphologic that mimic the changes observed in human posterior subcapsular and cortical cataract (Gupta, 2004). IN VITRO MODELS IN CATARACT (Gupta, 2004) Induction of cataract in isolated animal lenses maintained in organ culture has become a convenient, quick and appropriate method for testing the anticataract efficacy of an agent. Opacification of lens is induced by generating oxidative stress/ hyperglycemic/ hypergalactosemic conditions around the lens by supplementing the culture medium with a variety of exogenous substances. 1. Oxidative stress induced cataract Oxidative mechanisms play an important role in many biological phenomena including cataract formation. Formation of the superoxide radical in the aqueous humor, lens and its derivatization to other potent oxidants may be responsible for initiating various toxic biochemical reactions leading to the progress of cataract. In vitro such cataracts are induced by agents like selenium, H2O2, photosensitizers and enzyme xanthine oxidase. 2. Selenite induced cataract In vitro cataract is produced by supplementing the tissue culture medium with 25 to 100 mM sodium selenite in which freshly enucleated transparent rat lenses are incubated at 370C. This causes membrane damage and faint cortical opacities within 24 h. 3. Photochemically induced cataract Riboflavin, a photosensitizer, is supplemented in the culture medium to induce cataract in cultured lenses. Micro quantities (4-200  Ã‚ ­M) of riboflavin lead to severe physiological damage and opacification within 24 h after exposure to light. The initial membrane damage is evidenced by a disturbed cation ratio between lens water and the medium of incubation. Riboflavin on getting photosensitized generates free radicals in a sequence of reactions. Lenses are maintained in organ culture for 24 to 72 h. The lenses are divided into four groups and incubated in the dark and light both in presence and absence of riboflavin. The lenses are exposed to light with two 15-w daylight fluorescent lamp placed at 8 inches above the cluster plate. The culture medium is replaced every 24 h. Riboflavin shows no effect on the lens in the absence of light, and light without riboflavin has no significant effect. opacification starts in the equatorial zone and gradually extends towards the centre of the lens. 4. Enzymatically induced cataract Supplementation of culture medium with 1 mM xanthine and 0.1 unit xanthine oxidase, which act as substrate and enzyme respectively, leads to generation of superoxide radical. The lenses suffer severe oxidative damage and turn opaque within 24 h when incubated in culture medium at 370C. 5. Hydrogen peroxide induced cataract Incubation of lenses in medium containing 50-500  Ã‚ ­M H2O2 and it produce cataract. Opacification starts in the equatorial region within 24 h. The entire superficial cortex becomes opaque by 96 h. Due to the high instability of H2O2, the medium is changed every 2 h during the first eight hours. 6. Sugar induced cataract Transparent and undamaged lenses are incubated in a basis culture medium with fetal calf serum for 24 to 48 h. In the control group the medium is supplemented with glucose (30 mM), lenses develop opacity in the subcapsular region on day 1 and in the central region on day 2. Biochemical analyses reveal raised polyol, malondialdehyde levels and water content, and decreased glutathione levels in these lenses. 7. Steroid induced cataract Steroid-induced experimental cataract is produced in vitro by incubating the transparent lenses in the medium containing methyl prednisolone (1.5 mg/ml). The test agent and methyl prednisolone added alone and together to the medium form drug control, control and treated groups respectively. Early cataract around the equator is produced within 24 h of incubation. Incubation period may be extended to 48 h for dense opacity. Morphological changes and modulation in biochemical parameters between the groups may show the potential of the anticataract agent. 8. Naphthalene induced cataract TC-199 medium is used for the preincubation of lens. Stock solution of napthalene dihydrodiol is prepared in 20% ethanol at 2.5-10-3 M concentration. The stock solution is diluted 1:100 to obtain the final concentration of 25.5 -10-5 M. The final osmolarity of the solution is 295-300 m Osmol. Rat lenses are incubated in TC-199 medium containing napthalene metabolite solution. Medium is renewed daily till 72 h. Lenses remain clear during the initial 24 h but from shell-like opacity around the nucleus by 48 h. Opacification becomes more peripheral and widespread after 72 h. At 48 h, under such conditions of incubation, development of opacity mimics the in vivo napthalene cataract. Naphthalene is oxidized in the liver first to an epoxide and then is altered into naphthalene dihydrodiol. This stable component on reaching the eye gets converted enzymatically to dihydroxynaphthalene. Being unstable at physiological pH, 1,2 dihydroxynapthalene sponaneously auto oxidises to 1,2 naphthoquinon e and H2O2. It alkylates proteins glutathione and amino acids and generates free radicals. There is a loss of protein thiol in this reaction and the products are less easily digestible by pancreatin than normal lens protein (Rees and Pirie, 1967). 9. Ca2+ induced cataract In this model, the control group contains the lenses incubated in the medium enriched with 20 mM Ca2+ or 1x 10-2 mM A23187 calcium ionopore. The treatment group lenses are cultured in the calcium and the test drug-containing medium. Incubation period can range from 24-72 h (Gupta, 2004). Fig.6 Mechanism of action of glucose-induced cataract C:UsersDHINESHDesktopUntitled 7.png Under physiological conditions, glucose is metabolized through the glycolytic pathway. An excess amount of glucose is converted to sorbitol by enzyme aldose reductase via polyol pathway. The glucose conversion into sorbitol by utilizing NADPH results in the reduction of NADPH/NADP+. Moreover, sorbitol undergoes oxidation to fructose by using sorbitol dehydrogenase (SD). Sorbitol does not easily cross cell membrane. Intra lenticular accumulation of sorbitol, leads to lens damage (Kyselova, 2004). Fig.7 Biomorphological changes during cataract formation C:UsersDHINESHDesktopUntitled 66.png As, the lens starts to swell in response to the hyper osmotic effects of polyol accumulation, membrane permeability changes resulting in an increase in lenticular sodium and decrease in the levels of lenticular potassium, reduced glutathione, ATP and free amino acids. The overall antioxidant status of the lens decreases because of depletion of GSH (Kyselova, 2004). Mechanism of action of calcium-induced cataract Fig.8 Calcium transport pathway Increased levels of lenticular calcium activate calcium dependent proteases. The activated proteases hydrolyze cytoskeletal proteins and lens crystalline. Crystalline cleavage would result from lower molecular weight peptides that could, in turn, aggregate to form higher molecular weight proteins (Wang et al., 1996). Various methods for the prevention of cataract The development of newer drugs for treatment of cataract mainly aims, interacting at the level of changed lens metabolism and lens pathophysiology. The in vitro, in vivo studies are used to identify the anti cataract agents. This epidemiological studies may be widely classified in the following categories (Gupta et al., 1997). Aldose reductase inhibitors Agents acting on glutathione Nonsteroidal anti -inflammatory drugs Vitamins, minerals and antioxidants Miscellaneous agents. 1) Aldose Reductase Inhibitors These drugs are aimed to prevent the metabolic dysfunctions of diabeties by polyol pathways. Aldose reductase inhibitors prevents the accumulation of sorbital within the lens would have an osmotic effect bringing in water and causing swelling and opacification. Sorbinil a spirohydantoin became the most powerful sorbitol lowering agent. Sorbinil prevents increased fluorescence and protein aggregation and it also acts as an antioxidant. 2) Non Steroidal Anti inflammatory Drugs The NSAIDS broadly studied are paracetamol, aspirin, Ibuprofen, sulindac, naproxen, and bendazec. The NSAIDS provide adequate productive effect to lens protein through various steps like acylation, carbamylation and inhibition of glycocylation. Some of them are also reported to inhibit lens AR to varying extent. NSAIDS contains antioxidant properties also. Most of the studies on the evaluation of anticataract potential of drugs have been conducted by feeding the drugs by oral route. 3) Agents which act on glutathione Glutathione is a tripeptide thiol known to control calcium inflex and protect lens protein from various agents like glucose and galactose. With advancing of age there is a considerable decrease in the concentration of glutathione and the decrease more prominent in lens with cataract. 4) Vitamins, minerals and antioxidants If oxidation in lens leads to cataract formation, then is feasible to prevent it by the use of antioxidants such as vitamins C and E and perhaps ÃŽ ²-carotene. The potential role of vitamins and antioxidants in preventing various diseases is well documented there are reports suggesting beneficial effect of vitamins like C and E in preventing cataract. Beta -carotene has also been demonstrated to protect lens damage by hematoporphysin. Ascorbate protects rubidium uptake against free radical damage and prevents light induced protein cross linking. Protective effect of vitamin C has been also reported in various in vitro studies. Vitamin E has been found to delay cataractogenesis in diabetic rats and in Emory mouse. Vitamins C and E,  Ã‚ ¢- Carotene and other anticataract agents probably act via a common mechanism of their scavenging properties of free radicals (Gupta et al., 1997b). Antioxidant enzymes 1) Superoxide Dismutase (SOD) SODs are a family of metalloenzymes that transfer superoxide in to hydrogen peroxide (H2O2) and represents the first line of defence against oxygen toxicity. 2O2- + 2H → H2O2 + O2 Three isoforms of SOD have been found. The first is mainly found in the cytoplasm of cells and it containing Cu and Zn at its active site (Cu/Zn SOD-1), the second containing Mn at its active site is located in mitochondria (Mn SOD-2) and the third (Cu/Zn SOD-3) is present in the extracellular fluid like plasma. SOD is a stress protein which is synthesized mostly in response to oxidative stress. It is found that little amount of Cu, Zn and Mn metals are crucial for maintaining the antioxidant activity of SOD (Halliwell, 1994; Ray and Husain, 2002). 2) Glutathione Peroxidase (GPx) GPx is one of the most important enzymes responsible for the degradation of organic peroxides and hydrogen peroxide in the brain. GPx catalyse the oxidation of GSH to GSSG at the expense of H2O2. There are two isoforms have been identified, selenium-dependent which is highly active towards H2O2 and organic hydroperoxides and selenium independent GPx. GPx activity has been reduced in selenium deficiency (Muller et al., 1984; Son et al., 2007). 3) Catalase (CAT) It is a heme-containing protein present in most cells. 2H2O2+ 2H2O → O2 Catalase is 104 times faster than GPx. It is having four protein subunits, each containing a heme Fe (III)-protoporphyrin group bound to its active site. GPx and CAT were found to be important in the inactivation of many environmental mutagens (Ray and Husain, 2002). 4) Glutathione (GSH) GSH has major intracellular antioxidant molecule and it is a tripeptide synthesised by enzymatic reaction involving two molecules of ATP from aminoacids like glutamate, glycine and cysteine. It plays a very crucial role in detoxification of peroxides and electrophilic toxins, mainly by acting as a substrate for GSH transferase and GSH peroxidase. It was shown that weakening of GSH enhances cerebral ischemic injury in rats (Mizui et al., 1992; Son et al., 2007).

The Dangers Of Diet Aids :: essays research papers fc

THE DANGERS OF DIET AIDS   Ã‚  Ã‚  Ã‚  Ã‚  About a month ago, I stepped onto my bathroom scales. When I looked down at the numbers, my fears were confirmed: I had gained 5 pounds. Overcome with a desire to shed this unwanted extra weight, I decided to join millions of Americans just like me, and buy some sort of diet aid to help me along. I had no idea what to look for, what to avoid, and possible side effects, so I began to research the different types of diet aids, both chemical and herbal, and was hit with some very disturbing facts.   Ã‚  Ã‚  Ã‚  Ã‚  It has been estimated that nearly 10 million women in the U.S. buy over-the-counter diet aids.(Cottrell, 99) Diet aids come in the form of pills, tablets, capsules, powders, milkshakes, herbal teas, and candies. They work in one of two ways, either by suppressing the appetite or by producing a feeling of fullness that encourages the eater to limit her food consumption.(Cottrell, 99) This feeling of fullness is often brought about by the ingredient guar gum, which forms a gel in the stomach. It has not been proven, though, that guar gum has a benefit for weight reduction.(Cottrell, 99)   Ã‚  Ã‚  Ã‚  Ã‚  Amphetamines, which suppress the appetite, are a common ingredient in many over-the-counter diet aids. They are also commonly found in other drugs such as Speed, Crystal, White Crosses, 357 Magnums, Black Beauties, Crank, Ice, and Meth, most of which are illegal.(Cottrell, 99) Amphetamines increase heart and breathing rates and blood pressure, and dilate pupils. Users can also experience a dry mouth, sweating, headache, blurred vision, dizziness, sleeplessness, and anxiety.(Cottrell, 100) Extremely high doses can cause usersto flush or become pale; they can cause a rapid or irregular heartbeat, tremors, loss of coordination and even physical collapse.(Cottrell, 101) Toxic psychosis, delusional thinking and even death can also occur. Long-term heavy use of amphetamines can lead to malnutrition, skin disorders, ulcers, and various diseases that come from vitamin deficiencies.(Cottrell, 101) Lack of sleep, weight loss, and depression also result from regular use. When people stop using amphetamines abruptly, they may experience fatigue, long periods of sleep, irritability, extreme hunger and depression.(Cottrell, 101) The length and severity of the depression seems to be related to how much and how often the amphetamines were used.(Cottrell, 101)   Ã‚  Ã‚  Ã‚  Ã‚  Another common ingredient that is chemically related to the amphetamine, is Phenylpropanolamine (PPA), the only FDA-approved over-the-counter weight loss drug.(Cottrell, 100) PPA, the active ingredient in Dexatrim, Acutrim, and most other diet aids, acts on the appetite center in the brain, the hypothalamus, reducing the desire to eat.

The Feasibility of Utillizing Basella Rubra

People nowadays use alugbati nightshade leaves for cooking and throw away the stems. Instead of throwing the stems, why not investigate a product from utilizing Basella Rubra (Alugbati) stems that will be a great help to the industry. Utilizing the stems of Basella Rubra is also practical and economical for the users. This kind of plant is abundant even found in backyards here in our country. It has spread throughout the tropical countries and one of the best tropical spinach widely adapted to a variety of soils and climates. Malabar n. has thicker tender stems. It is a good source of vitamins A, C and iron. The researchers decided to make Alugbati stems as a skin moisturizer because it possesses that commercial moisturizers have like: emollients. This helps the skin to be moisturized and soften. This study aims to produce and attempts to discover the capability of alugbati stems as a substitute for commercial skin moisturizer. It also aims to produce product that is less expensive and acceptable for people who has skin problems. Significance of the Study: This study is significant especially to persons that has a problem on dryness of the skin because they don’t have to buy an expensive skin moisturizer for there is already a substitute to it that is cheaper and environmentally friendly product. Statement of the Problem: Is it possible to make a skin moisturizer out of alugbati stems? Are there any properties of alugbati stems that can be used as a skin moisturizer? Hypothesis: It is possible to make a skin moisturizer out of alugbati stems and there are also properties of alugbati stems that can be used as a skin moisturizer. Materials and Equipments: The materials that will be use are clean containers, strainer, mortar and pestle, Alugbati stem, Glycerin, and perfume oil. Variables: The independent variables are: (1) Water (2) amount of Glycerin and (3) amount of perfume oil while the dependent variable is the Basella Rubra (Alugbati) stem. Procedures: The procedures in making a skin moisturizer out of alugbati stems are: (1) Wash the alugbati stem and sterilize the containers to be use. (2) Peeling the skin of the stem of alugbati using knifes or hands. 3) Pounding of the stem of the alugbati using the mortar and pestle. (4) Add a little amount of water then pound again until it becomes subtle. (5) Strain to separate the extract and the stem. (6) Cool it aside. (7) Add glycerin that will make it a moisturizer and perfume oil to enhance its fragrance. Review of Related Literature: Glycerin is a neutral, sweet-tasting, colorless, thick liquid which freezes to a gummy paste and which has a high boiling poi nt. Glycerin can be dissolved into water or alcohol, but not oils. On the other hand, many things will dissolve into glycerin easier than they do into water or alcohol. So it is a good solvent. Glycerin is also highly â€Å"hygroscopic† which means that it absorbs water from the air. Example: if you left a bottle of pure glycerin exposed to air in your kitchen, it would take moisture from the air and eventually, it would become 80 per glycerin and 20 percent water. Because of this hygroscopic quality, pure, 100 percent glycerin placed on the tongue may raise a blister, since it is dehydrating. Diluted with water, however, it will soften your skin. While people say this softening is the result of the glycerin attracting moisture to your skin, there is heated debate as to whether or not the glycerin has some other properties all its own which are helpful to the skin. Summed up, the current thinking is â€Å"We know glycerin softens the skin. Some people think its because it attracts moisture, but there could be other reasons. † Glycerin has lots of uses besides being used to make nitroglycerin (note: glycerin is not an explosive substance by itself. It has to be turned into nitroglycerin before it becomes explosive, so it’s safe to work with in your kitchen). Some uses for glycerin include: conserving preserved fruit, as a base for lotions, to prevent freezing in hydraulic jacks, to lubricate molds, in some printing inks, in cake and candy making, and (because it has an antiseptic quality) sometimes to preserve scientific specimens in jars in your high school biology lab. http://pioneerthinking. com/crafts/what-is-glycerin Moisturizers or emollients are complex mixtures of chemical agents specially designed to make the external layers of the skin (epidermis) softer and more pliable. They increase the skin's hydration (water content) by reducing evaporation. Naturally occurring skin lipids and sterols, as well as artificial or natural oils, humectants, emollients, lubricants, etc. , may be part of the composition of commercial skin moisturizers. They usually are available as commercial products for cosmetic and therapeutic uses, but can also be made at home using common pharmacy ingredients. Moisturizers prevent and treat dry skin, protect sensitive skin, improve skin tone and texture, and mask imperfections. ttp://en. wikipedia. org/wiki/Emollient Alugbati is a plant used a vegetable. It is rich in calcium, Vitamin B (Thiamine, Niacin & Riboflavin) and Vitamin C. It is a laxative and has soluble fiber that acts like magnet to ingested fat and subsequently reduce the risk of cardiovascular diseases. Regularly eating alugbati will help reduce degenerative disease. Red alugbati has the added property of higher amounts of xanthones, an antioxidant. It can also impro ve and regularlize bowel movement. B-complex vitamins help improve blood vessel strength. http://gonatural. com. ph/herbalblog/alugbati-scientific-name-basella-alba-basella-rubra-linn/ Alugbati is a succulent, branched, smooth, twining herbaceous vine, several meters in length.

Law of Definite Proportions Definition

Law of Definite Proportions Definition The law of definite proportions, together with the law of multiple proportions, forms the basis for the  study of stoichiometry  in chemistry. The law of definite proportions is also known as Prousts law or the law of constant composition. Law of Definite Proportions Definition The law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. The mass ratio of elements is fixed no matter where the elements came from, how the compound is prepared or any other factor. Essentially, the law is based on the fact that an atom of a particular element is the same as any other atom of that element. So, an atom of oxygen is the same, whether it comes from silica or oxygen in air. The Law of Constant Composition is an equivalent law, which states each sample of a compound has the same composition of elements by mass. Law of Definition Proportions Example The law of definite proportions says water will always contain 1/9 hydrogen and 8/9 oxygen by mass. The sodium and chlorine in table salt combine according to the rule in NaCl. The atomic weight of sodium is about 23 and that of chlorine is about 35, so from the law one may conclude dissociating 58 grams of NaCl would produce about 23 g of sodium and 35 g of chlorine. History of the Law of Definite Proportions Although the law of definite proportions may seem obvious to a modern chemist, the manner in which elements combine was not obvious in the early days of chemistry through the end of the 18th century. French chemist Joseph Proust (1754–1826) is credited with the discovery, but English chemist and theologian Joseph Priestly (1783–1804) and French chemist Antoine Lavoisier (1771–1794) were the first to publish the law as a scientific proposal in 1794, based on the study of combustion. They noted metals always combine with two proportions of oxygen. As we know today, oxygen in the air is a gas consisting of two atoms, O2. The law was hotly disputed when it was proposed. French chemist Claude Louis Berthollet (1748–1822) was an opponent, arguing elements could combine in any proportion to form compounds. It wasnt until English chemist John Dalton (1766–1844)s atomic theory explained the nature of atoms that the law of definite proportions became accepted. Exceptions to the Law of Definite Proportions Although the law of definite proportions is useful in chemistry, there are exceptions to the rule. Some compounds are non-stoichiometric in nature, meaning their elemental composition varies from one sample to another. For example, wustite is a type of iron oxide with an elemental composition varying between 0.83 and 0.95 iron atoms for each oxygen atom (23%–25% oxygen by mass). The ideal formula for iron oxide is FeO, but the crystal structure is such that there are variations. The formula for wustite is written Fe0.95O. Also, the isotopic composition of an element sample varies according to its source. This means the mass of a pure stoichiometric compound will be slightly different depending on its origin. Polymers also vary in element composition by mass, although they are not considered true chemical compounds in the strictest chemical sense.

Night owl Essay Example | Topics and Well Written Essays - 1250 words

Night owl - Essay Example This however does not negate the fact that good sleeping patterns should not be advocated for. It is not only vital but also health for persons to get the right amount of sleep each day. Much praises has not been languished towards the night owls as the early birds. However, Jacques (Para 3) explains that there are reasons the owl persons to be proud of who they are. She argues that one of the reasons to be proud if an individual is an evening person is that they might be having an IQ that is relatively higher. At the London School of Economics and Political Science, an evolutionary scientist called Satoshi Kanazawa found out the possibility of a connection or relationship between evolutionary adaptive behaviors and intelligence. It is a deviation from what ancestors did. Jacques (Para 4) activities that are routinely nocturnal are evolutionarily novel and were most likely seldom in the ancestral environment. The conclusion of the study revealed that intelligent children have the highest probability of growing up and becoming nocturnal in adulthood by going to bed both on weekends and weekdays late and waking up late. However, despite the fact that their IQ may be higher, the early birds tend to in a slightly better position for success. According to Jacque (Para 5), the second reason for the evening persons to be proud is that they usually benefit from the having strength at night. They have an advantage in terms of physicality in comparison to the morning people. The tests from researchers of the University of Alberta on the strength of legs of both morning and evening persons reveals that while the early birds exhibit consistent strength throughout the day, the night owls strength peaks at night to higher levels. This is attributed to the fact that nocturnal persons shows increase in excitability in the spinal cord and motor cortex. Jacque (Para 6) claims that individuals who tend to work more at night are to be a little more

Portfolio Management & Construction Essay Example | Topics and Well Written Essays - 9000 words

Portfolio Management & Construction - Essay Example Qatar produces nearly 776 thousand barrels of oil each day and this current level of production is estimated to last for 54 years. When it comes to natural gas, the country is richest if all in the GCC countries. At the end of 2008, its natural gas reserves stood at 25.56 trillion cubic meters, representing nearly 61% of the entire GCC natural gas reserves and nearly 14% of the world’s natural gas reserves. In the GCC region, the country can be called as one of the most stable countries, given its prudent macroeconomic management and combination of natural resources. Due to higher global demand of energy, the economic boom continued till the end of 2008. In the past six years, the economy of Qatar grew as much as five times in size from 2002 to 2008, with an annual rate of 31.6% on average that makes nearly $19.6 billion (2002) to $100.4 billion (2008). The reason of such massive growth is steady increase in energy prices as well as surging gas and oil production. The country has allowed significant foreign investment in the production of its gas field in the past decade and is predicted to become world’s largest Liquefied Natural Gas (LNG) exporter in the future period of time. The country is also pursuing to attract foreign investment in the production of its other sectors such as non-energy projects by liberalize the economy even more. However, the global economy experienced drop in oil prices in late 2008 as well as economic and global financial crises that ultimately reduced the budget surplus of the economy and resulted in sluggish pace of development projects and investments in 2009. It is expected that economic growth will rebound and the economic policy emphasizes on developing the non-associated natural gas reserves of Qatar and improving foreign and private investment in non-energy sectors but gas and oil sector is still central in the

Creating a Plan for Positive Influence Essay Example | Topics and Well Written Essays - 1000 words

Creating a Plan for Positive Influence - Essay Example Managers have a greater role to play in shaping the different emotions exhibited by their employees and create an atmosphere in the workplace where the employees feel motivated thus creating an improved performance in the organization. This paper will therefore discuss the differences in personality, values, emotions and attitudes as well as how all these elements influence behavior. Finally there will be a discussion on how these differences can be implemented effectively in to a plan so as to influence the team positively. The Differences in Personality, Attitudes, Values and Emotions and how They Influence Behavior Yang and Diefendorff (2009) points out that an attitude usually shows how an employee feel about something that relates to him or her and has three main components which include the cognitive, affective and behavioral. the cognitive aspect of attitude elaborates on the truthfulness of an individual concerning certain issues for example in the workplace setting employees knows very well that visiting social sites while at work is prohibited therefore those visit such sites are on the wrong and it can be said that this type of attitude is right and is cognitive. The affective aspect elaborates on how an employee feels about a certain situation for example in the case above an individual might state he or she dislikes visiting the social sites during the working hours thus this aspect shows how an employee affectively feels about visiting social sites during working hours and those individuals who visits those sites. The behavioral aspect of attitude shows how an employee feels through an action in the work place. Values refer to the life goals that are set out by the individual that reflects what is important to them. Values are gained from the experiences of the daily occurrences thus making the stable. Important values in the life of an individual affect the decisions that this individual makes in the work place. The attainment of an individual’s values in the organization is likely to make the individual remain in the organization and when the job does not satisfy a person’s values this individual is likely to leave the job. In the case of behaviors, an individual is likely to choose a job that posses high values and that he or she values them (Garrety, et al., 2003). The personality of any individual include the person’s feelings, behavioral patterns and thoughts and the success of an institution is highly dependent on how the leaders are able to understand the personalities of the people within the organization. By understanding the pers onality of a certain individual within the organization makes it easier for managers to gauge how the employees are likely to behave when faced with certain issues. In the institutional setting each and every individual has a role to play thus he or she is required to behave in a certain manner that is expected of them in the office etiquette. In jobs that require more independence or freedom, then personality usually tends to exert a much strong influence on the behavior of people in the workplace (Morris & Feldman, 1997). Developing the Plan The completion of the project will take one year and during this time different activities will be undertaken. The team will need to stay focused throughout the period which the project is being undertaken thus there is need to for the team members to be motivated

Hog case study Essay Example for Free

Hog case study Essay Product Life Cycle: Late Growth / Early Maturity I. Uncertainties that may affect industry structure II. The plausible assumptions about each important causal factor The uncertainties that exist for the Motorcycle Industry are fluctuations in the following categories: government regulations, price of supplies, Fuel Cost, Global Demand for motorcycles, Product innovation, customer loyalty value (CLV), target market, and market share. The casual factors that drive these uncertainties are an important factor when forecasting the future of the Motorcycle Industry. The most likely scenario for government regulations will push the industry towards going â€Å"Green† and becoming more environmentally friendly by requiring lower emissions. They will require the industry to improve these emissions standards. Currently the average motorcycle averages 40 MPG (miles per gallon) in the city and 50 MPG on highway but they still emit smog into the environment. The industry will most likely use the fuel consumption statistics to their advantage by relating to the current price of gasoline and the fact that the average car gets 20 MPG and SUV’s get even less at about 16 MPG. Price will be a major uncertainty for the industry. The industry relies on other companies to provide them with materials so that they could assemble the bike. The increasing cost of transporting these materials from the manufacturers to the motorcycle assembly plants are going to increase and therefore lead to increase in the operating cost for the industry and lead to higher price for the finished product resulting in no value added. The price of the finished product is a very important factor for the industry because all the players in the industry are trying to attract the younger target market and are competing on price. The Japanese manufacturers have a mindset that they are willing to incur short-term loss so that they could gain market share. This strategy is bad for the industry because every company will try to reduce its prices and will eventually not be able to make significant profit. This fact needs to be carefully monitored so that no one player tries to influence the overall industry. Economic conditions in the U. S. significantly affect the firm’s performance from year to year. During an economic recession, Harley-Davidson will feel its effects since consumers tend to tighten up discretionary spending during rough times resulting in no value added to the company. This is what is currently happening in the economy. Global demand fluctuation also is an important factor to the overall success of the industry. The global demand for the heavy weight motorcycles grows at an average core rate of 7% to 9% per year and has averaged 8. 6% since 1991 for Harley Davidson. This trend will most likely continue because of the Baby-Boomers who previously purchased these bikes will continue to do so as they live more active and adventurous lives then previous generations. The baby boomers are more affluent then previous generations. The global demand will rise because of this fact. It will also rise because they are not only catering to the older consumers but also towards the younger generation and women. The industry is creating bikes that are cheaper and faster that appeal to the younger consumer. This trend will spread globally because of the Blue Ocean created by Harley Davidson because of the Rental Programs, and the Riders Edge programs that will be emulated by the other players in the industry. This will lead to the Red Ocean scenario again and companies will compete at the same level within the industry. We also believe that players in the industry will make strategic alliances with other industries to cross sell their products such as Harley currently produces clothing and accessories to increase and diversify its revenue sources. The industry will continue to compete on all aspects such as price, quality, and functionality. This intense competition will lead to a Red Ocean until a new innovator can emerge. The industry will most likely continue to invest in Research Development to improve the quality of their products, to try to innovate, to get a better product out to the market and even innovate the way they assemble and market their product to the consumer. Also, personalization and customization of motorcycles will increase as television programs such as American Choppers, and West Coast Choppers are glorifying them. All these factors will lead to an expansion of the Target market and more intense competition. Customer Loyalty Value will most likely rise for the industry because many of the individual producers have a wide variety of products that they can offer to their customers. The industry will most likely target previous customers more to get them to purchase a secondary bike. This trend will continue since the largest buyer group numbers are steady for the next several years, currently there are 41 million US men in the age group of 35 to 54 and that number increases to a little over 41 million in 2020. Also currently there are 80 million baby boomers of those the oldest ones are entering their late 50’s and the youngest boomers are just entering earlier part of their 40’s. These groups will be heavily targeted by the industry to either purchase their first motorcycle or 2nd motorcycle. III. Plausible assumptions about each important casual factor The most important casual factors are the level of quality of the motorcycles, product innovation and marketing. These three factors are predetermined meaning that change is likely to happen  nd is largely predictable and they are constant meaning that these areas in the industry are unlikely to change. However, product innovation is uncertain meaning that product innovation depends on other irresolvable uncertainties in the industry. To begin with the first important casual factor the level of quality, we know that if the level of quality for motorcycles increase, it is likely to lead to an increase in other areas as well such as price, sales, market share and customer retention. (Cash flow, interrelationship, linkages and value added). The next important casual factor is product innovation. Similar to quality, if product innovation increases it is likely to lead to increases in other areas such as price, sales, market share, customer retention and gaining new customers. Lastly, marketing is another important casual factor. We know that if marketing is increased and if it becomes more innovative in ways there will be increases in other areas such as sales, market share, customer retention, new customers, advertising and promotion, branding and in relationship marketing resulting in value added. IV. Assumptions about individual factors into internally consistent scenarios. Scenario 1: If quality increases it is likely that performances in other areas are likely to increase as well. Improving quality is always beneficial and important to execute any strategic sequence successfully. The value curve, which is the basic component of the strategy canvas, depicts relative performance across the industry’s factors of competition. Creating a new value curve involves identifying which factors of the industry should be eliminated, reduced, raised well above and created or offered in regards to the industry. So let’s use Harley-Davidson as an example. Eliminate-Reduce-Raise-Create Grid: Harley-Davidson Eliminate Company staff positions Raise Tariff protection against global competitors Reduce Inventory levels Create JIT inventory practice Employee involvement Materials-As-Needed program When it came to improving the quality of the business Harley-Davidson eliminated the positions of senior vice president in marketing and operations because there was no value added. The style of leadership at the company was very effective because they were able to identify weak links in their operations and cut out the extra manpower that was muda. The company reduced inventory levels with the hope that it would make quality problems more apparent and force employees to take action. The tariff protection the company sought to gain time and protect itself from the Japanese inroads in the heavyweight segment was a leading factor that raised them above the industry standards. The company’s OWC that was created was the use of JIT inventory practices, employee involvement and the SOC (statistical operator control). Workers were required to participate in the newly formed circles that were made directly responsible for improving motorcycle quality. A Materials-As-Needed (MAN) program was implemented to free up, as much needed cash by reducing WIP inventory, which led to economies of scale and LC. These changes also led to increased quality. Productivity improvement went up by over 50%, WIP inventory was reduced by 75%, scrap and rework went down by 68%, U. S. revenues increased by over 80%, international revenues by 1. 7 times, operating profits increased by $59 million and market share in the heavyweight segment increased by 97%. Harley-Davidson’s net revenue increased from $1,350,466 in 1995 to $5,015,190 in 2004 in millions. Scenario 2: If product innovation increases it is likely that performances in other areas will increase as well. Product innovation is the new business imperative. It drives growth and future success for companies. Most companies are trapped competing in red oceans because they define their industry similarly, focus on the same buyer group, define the scope of the products and services offered by their industry similarly and they focus on the same point in time and often on current competitive threats in formulating strategies. However, Harley-Davidson has not followed these same guidelines, so they are not currently trapped in the red oceans. Harley-Davidson was selected as an outstanding corporate innovator by PDMA in 2003 (Product Development Management Association) because of its established brand, its strong connection with customers, and because of its continued commitment to product innovation. The company focuses on optimizing the â€Å"customer experience,† and as a company has grown from 40,000 units/year in 1998 to 264,000 units/year in 2002. Their use of multiple and novel venues to gather customer needs and preferences information to guide their new product efforts, while employing a formal Concurrent Product Process Delivery Methodology (CPPDM), has kept their new product engine running at peak efficiency. Several unique elements and concepts in their process such as â€Å"swirl,† â€Å"bins,† and â€Å"cadence,† ensure the degree of innovation, speed to market, match of development resources, and financial viability of individual projects as well as the entire new product portfolio. Scenario 3: If marketing increases performances in other areas is likely to increase as well. Marketing for any company in any industry is extremely important. How well a product/company is marketed leads to the success of that product/company. Blue oceans are defined by untapped market space, demand creation and the opportunity for highly profitable growth. In order to execute a blue ocean strategy market boundaries must be reconstructed and must reach beyond existing demand. This is in fact what Harley-Davidson did to create a blue ocean for itself and increase the brand name and company revenues simultaneously. The company’s three strategic constants: passion, sense of purpose and operational excellence are the cornerstone of their blue ocean strategy. There is no competition, as seen by being the only U. S. manufacturer for 46 years, and petition to end protective tariffs. All bikes are customizable, and some say that they are made to be tinkered with (not as hands-off as can be, therefore redefining premium brand). The company has a huge fan club and a phenomenally powerful brand and its quintessential strong emotional connection keeps them in the leadership position. Undoubtedly, Harley-Davidsons greatest marketing asset is the Harley Owners Group, with one million member’s world wide making it the largest motorcycle-sponsored club in the world. Harley-Davidson is continuing to improve value innovation by still focusing on beating the competition, making it irrelevant by creating a leap in value for buyers and their company by opening up a new and uncontested market space. They have done this with the implementation of their Rider’s Edge and Rental Programs. The rental program was implemented to hook customers and entice them to buy a Harley. This program is offered by 250 dealers and is available in 52 countries. Survey shows that 32% bought a bike or placed an order and another 37% planed to buy within one year. The Rider’s Edge Program offers riding lessons that last for four days and cost students $350. Approximately 70% of students in the program purchase a motorcycle within 18 months and about 40% of the students are women and 30% are under the age of 35. This buyer learning relationship created by Harley-Davidson has increased sales, new customers and targets the untapped market of women highly. This value innovation has led to LC for people who have learned to ride the motorcycles through the program and also to the instructors teaching the students. It has led to increased sales and revenues from the 70% of students that buy within 18 of completing the lessons. This continues to be a huge win for Harley-Davidson. V.

We will determine the future industry structure, implications for industry structural attractiveness and the sources of competitive advantage. The future growth is largely dependent upon its ability to develop and successfully introduce new, innovative and compliant products. In addition, it must comply with governmental laws and regulations that are subject to change and involve significant costs. Worldwide demand for motorcycles is forecasted to advance to 5. 2% annually to more than 35% million units in 2007, valued at $46 billion. Driven by increased income levels in emerging markets such as India, China, and Southeast Asia, demand for scooters, mopeds and light motorcycles will remain relatively strong, providing continued growth opportunities for motorcycle OEMs and suppliers. The market for large motorcycles will also remain strong, although some concerns regarding future demand have emerged due to the aging customer base and rising insurance costs, especially in the US and Europe. While growth prospects remain solid, especially when compared to the 2% annual growth experienced by the light vehicle industry, the industry will likely go through a restructuring phase in the future. Many of the small competitors will begin to exit the market. The intense focus on price in the Asia/Pacific region has caused Japanese OEMs to begin to abandon Japan as a production base in favor of lower cost hubs like China or Thailand. In China, for example, the largest motorcycle market and producer in unit terms, is rapidly transitioning away from motorcycle toward cars, and in the process overflowing the world market with motorcycle exports. In contrast, rising fuel prices and increasing restrictions on car uses are favoring motorcycles in developed markets. Two separate motorcycle markets exist. The first is centered in the industrialized Triad (US, Japan, Europe), where consumers who already have one or more vehicles see motorcycles as pleasure vehicles. These motorcycles tend to be larger, more powerful machines, which cost on average about $5,000 to $6,500. The other much larger market in unit terms is found in the emerging economies of the Asia/Pacific, where motorcycles are seen as primary family and work vehicles. These vehicles are cheaper, smaller and less powerful than Triad motorcycles. Motorcycles everywhere is being fractured down from, stricter emissions controls to noise limits, from land closures to exclusions from HOV lanes. The motorcycle industry has spent the last 10 years of convincing the public that motorcycles are a form of entertainment and not a form of transportation. The world has been changing with new issues and now advertising is geared toward qualities like dependability, practicality, technology, safety and environmental friendliness. Women control 85% of all the discretionary dollars spent in the US. Ten years ago women represented about 3% of the motorcycle owners. In 2004, they ramped up to 12% in motorcycles. Utilizing learning curve, dealers are beginning to understand their sales people can no longer talk down to a woman. Some have started to hire women as salespeople. Once only men staffed dealerships, women are showing up as techs, service writers, parts counter, and unit salespeople. The behavior has changed. The Motorcycle Safety Foundation conducts training for new motorcyclists. In 2003, they reported that 40% of those signing up for new classes are women. In the case of Harley-Davidson, the Harley rider is now 45 (10 years ago it was 37) and 20% of Harley riders are over 55. Despite the company’s success in the past 18 years, it has difficult time attracting younger consumers, who tend, to go for sporty, fast, technologically-savvy racing bikes produced by its competitors. Harley has been investing in its product to attract a younger buyer. It continues to revamp its affordable Sportster line and its higher-tech V-Rod family with liquid-cooled revolution engines continues to appeal to more youthful market. In addition, its sports bike subsidiary, Buell, is to lure in the Generation Y market. Growth in year-to-year sales was slow, but with the economic downturn in the market, sales in this market segment may increase due to the lower price point. These marketing challenges will force the company to examine their manufacturing, marketing, pricing and every other part of the business. For consumers, this will means better pricing, more value and greater service to attract their more discerning and selective purchase. The industries never stand still. Operations improve, markets expand and players enter and exit. VI. Determining the sources of competitive advantage under the most likely scenario The driving force behind Harley-Davidson’s competitive advantage is its quality, marketing and product innovation so we will determine the sources of competitive advantage in these forms. Quality Harley Davidson’s source of competitive advantage in regards to quality will most likely be its continued use of the productivity triad. Harley’s productivity triad involves employee involvement, use of JIT inventory practices (which Harley renamed MAN – Materials As Needed) and statistical operation control. Quality drives productivity and increased productivity is a source of greater revenue. This can be seen as under Harley’s new system inventory turn increased to 17 and productivity improvement went up by over 50%. This new system allowed Harley to free up cash by reducing its work in process inventory by 75%. This system proves that improved quality does not always mean increased cost because its costs decreased while its U.S. revenues increased by over 80%, international revenues by 1. 7 times, and operating profits increased by $59 million. Their market share under this new system had also increased by 97%. Quality is defined entirely by the customer and end user and based upon that person(s) evaluation of his or her entire customer experience. Through the use of the productivity triad, customer retention will increase as Harley Davidson continues to improve its entire customer experience from how their bikes are sold (utilizing women sales people to make women customers more comfortable), to how the bikes perform. The increased customer retention and productivity triad will result in a differentiation advantage over its competitors thus creating superior value to its customers and superior profits for itself. Harley was able to create a blue ocean by driving costs down while simultaneously driving value up for its consumers. Marketing Harley Davidson’s source of competitive advantage in regards to marketing will most likely be the continued use of its programs such as the Ladies of Harley, the Riders Edge and Rental Program. The Ladies of Harley group cultivates and will most likely continue to cultivate the interest of women riders. This group was sponsored by HOG to support women motorcycle enthusiasts, and to encourage women to become more active within the group. The Riders Edge program offers motorcycle-riding lessons that last for four days and cost students $350. Surveys show that 70% of Rider’s Edge participants purchase a motorcycle within 18 months. This program helps to target the women market (who makes up 40% of participants) and younger riders (30% of participants who were under 35). The future strategy of Harley is to gain market share in the younger rider segment, so it is likely to continue this program. Harley will most likely continue the use of its rental program, which is used to â€Å"hook† customers and entice them to buy a motorcycle. It is said that 32% of participants bought a bike or placed an order and another 37% planned to buy one within a year after renting a Harley. The company will most likely increase the number of dealerships the program is offered in, as it has demonstrated great success. This is a value added to the consumer who gets to experience the feel of a Harley before making an actual purchase, and a value added to the company because it almost guarantees future earnings. These programs will result in a differentiation advantage over its competitors. Product Innovation In regards to production innovation, Harley-Davidson will most likely continue with new product development and upgraded manufacturing technology. With many concerns with environmental health issues, Harley will most likely manufacture a Hybrid or economically friendly motorcycle to entice sales of future consumers who are concerned with environmental conservation and to appeal to current eco friendly consumers. Harley-Davidson’s resources and capabilities together form its distinctive competencies. These competencies enable innovation, efficiency, quality and customer retention, all of which could be leveraged to create a cost or differentiation advantage for the firm and thus creating value for its customers and profits for itself. Harley-Davidson has created a strong differentiation strategy setting itself apart from the crowd and making its brand identity legendary. On the next page, you will find a competitive analysis of Harley-Davidson to one of its existing competitors, Honda. Competitive Analysis HARLEY DAVIDSON HONDA Future Goals?

Heavyweight Motorcycle market as compared to its major competitors. 2003 2007 US Heavyweight Market ShareUS Market Share 2007 2006 2005 2004 2003 Harley-Davidson 49. 4% 50% 49. 6% 50. 2% 50. 3% Honda 14. 2 15. 1 16. 6 18. 7 18. 4 Suzuki 12. 5 12. 9 12. 4 10. 2 9. 8 Yamaha 9. 2 8. 6 8. 9 8. 7 8. 5 Kawasaki 7. 2 6. 8 6. 5 6. 4 6. 7 However, Harley’s international market share is slightly smaller. For instance, the company has a 38. 4% Canadian market share and a 10. 2% market share in Europe as of 2006. Notably, both of those markets are substantially smaller than the US market. Nonetheless, Harley has a dominant worldwide market share of 33% in what is a growing industry. Operating Metrics Several operating metrics are useful in understanding the company’s position vis-a-vis its largest competitor. Honda’s figures are for its motorcycle business only. Please see chart on next page. 2006 Operating MetricsOperating Metrics Harley-Davidson Honda Units Sold 361 103 Units Sold per Employee 35. 4 3. 6 Revenue per Employee (USD) 637,881 356,746 Operating Margin(%) 27. 5 9. 2 CapEx as % of Sales 3. 8% 4. 2% While the company’s competitors, notably Honda Motor Company (HMC) and Suzuki, do not have as dominant a market position, they often have greater financial resources. This is largely because companies like Honda have more diverse product lines (like cars), and are greater in size than Harley-Davidson, a far more specialized company. For example, motorcycle sales at the company’s largest competitor, Honda, hover around 12% of total revenue. Revenue by Region While around 80% of the Harley Davidson’s sales still occur in the United States, its international segments are growing quickly, and the company is pursuing opportunities for gaining market share abroad resulting in value added. This can prove important to the company, as market share has begun to stabilize in the US due to saturation of this market. 12 Month Harley-Davidson Stock Analysis The chart above shows that it has definitely been a tough 12 months for Harley-Davidson stock and it is undoubtedly being affected by the economy. VII. Predicting competitor behavior under each scenario Introduction of competitor behavior In 2007, Sales in the motorcycle industry failed to increase after 14 consecutive years of gains and were lower than in 2006. For Harley-Davidson, revenues declined 1. 3% and earnings declined 4. 3% 2007. In preparation for the affects of a slowing American economy, the firms largest market, Harley cut production and shipment of its motorcycles in the 3rd and 4th quarters of 2007. However, on the up side, the motorcycle industry sales in 2007 were over the 1 million mark for the 5th straight year. Battery and tire sales indicate that ridership and enthusiasm for the sport remain high. Quality The competition will continue to manufacturer new models and invest in quality improvement; however, they will focus on supplying products with high quality at a reasonable price. In addition, they will strive to further improve JIT inventory practices and statistical operation control. Quality drives productivity and increased productivity is a source of greater revenue. Marketing The competition will market their brand with the younger generation. It will cater to younger buyers with smaller budgets. The aim to attract the younger target market and compete on price. Furthermore, create bikes that are cheaper and faster that appeal to this market. In addition, the current success that Harley has had with the rental’s, and the rider’s edge program will most likely be emulated by the players in the industry. Product Innovation The competition will continue to invest in product innovation that will appeal to the younger generation in design and price points. They will continue to create new technology that will offer new possibilities in mobility. Conclusion: Harley-Davidson has developed a blue ocean strategy by fulfilling dreams through the experience of motorcycling. All bikes are customizable and have developed a huge fan club and a phenomenally powerful brand with emotional connection and loyalty. This loyalty will be crucial to the company’s success going forward, and Harley will depend upon duplicating this success  internationally to fuel growth. Despite the fact that due to economic issues, in the motorcycle industry sales have been down and cost up, we expect that Harley-Davidson will continue to invest in quality improvement, marketing strategy and product innovation in order to remain competitive in the industry and achieve economies of scale. Harley-Davidson will continue to manufacturer new models and invest in quality improvement however; they will do it with increasing cost pressures. The dollar has lost 26% of its value against the euro and 11% of its value against the yen since March 2003. Escalating cost for the metals, plastics and other commodities used to manufacture motorcycles and the fuel needed to transport foreign models to the U. S. market, has resulted in price pressures for the European and Japanese manufacturers in particular. Harley will need to look to further cut manufacturing costs, (lean manufacturing) rather than raise retail prices for consumers who, in the U. S. , are continuing to tighten their belts. Harley-Davidson will continue to invest in marketing. Through marketing efforts the company will look to increase its current loyalty program but also duplicate this success internationally to fuel growth. The company’s customers tend to be fiercely loyal to the brand, which has helped to drive consistent growth over the past 20 years while making the company the premier name in its industry. In addition, since the company’s core consumer group is aging, it will target women and the younger generation of motorcycle enthusiasts. In order to appeal to this group, the company will continue to use the HOG and riders edge program. Furthermore, the company will continue to revamp its affordable Sportster line and its higher-tech V-Rod family with liquid-cooled revolution engines and its subsidiary, Buell, in order to lure in the Generation Y market. However, it should be noted that in marketing to this new segment, it will lead to the red ocean scenario again and companies will compete at the same level within the industry. The company will also have an opportunity to increase marketing in the international markets. While around 80% of the Harley Davidson’s sales still occur in the United States, its international segments are growing quickly, and the company will have an opportunity to market to these segments in order to gain market share abroad resulting in value added. This can prove important to the company, as market share has begun to stabilize in the US due to saturation of this market. Harley-Davidson will also continue to invest in product innovation. In order to increase its customer base, the company will focus more on fuel efficiency transportation oriented models in the coming years. With many concerns with environmental health issues, the company will most likely manufacture a Hybrid or an economically friendly motorcycle to entice sales of future consumers who are concerned with environmental conservation and to appeal to current eco friendly consumers.
