Gender Discrimination in the Job Market in South Korea Term Paper

Gender Discrimination in the Job Market in South Korea - Term Paper Example Women in all countries around the world report that they are paid lower salaries than their male counterparts are. According to the International Labor Organization ILO report, women earn about 20-30 percent less than what their male counterparts earn globally (Monk-Turner and Turner, 2003). Surprisingly, a survey conducted by ILO found that South Korean women as being the worst discriminated in the labor market. The ILO researchers found that Korean men have continued to enjoy a higher economic return than their female counterparts do. For instance, a survey conducted in 1988 by the ILO found that whereas Korean men earned an average salary of 2101 won, their female counterparts only earned an average wage of 1009 won. This indicates a huge wage gap compared to the average wage gap recorded I n other countries around the world. This wage gap implied that for every 48 won that a Koreans woman earned, their male counterparts earned 100 won. This translates to 48 percent wage gap. The ILO report also indicted that, early on in 1980, for every dollar that a Korean man earned, women early only 45 cents (Monk-Turner and Turner, 1994). This was the worst ever wage gap recorded in this time in the entire world. Despite the affirmative action and labor policies that have been enacted in South Korea, the labor wage gap between South Korean men and women and women have remained relatively higher that the global average. Factors Responsible For Gender Wage Gap in South Korean Labor Market Many people fail to understand why the gender wage gap has persisted in the Korean labor market despite the increased affirmative action going on in the country. However, a number of theories exist that may help in understanding the persistence of gender wage gap in the South Korean... Currently, Korea boasts to being the home of some of the leading electronic companies in the world. Some of the leading South Korean companies include Samsung and LG. Despite the achievements that the country has made in the past few years, gender discrimination remains one of the biggest challenges facing its labor market. Monk-Turner and Turner (2003) indicated that most companies in the country discriminate against the female gender. South Korean women face different kinds of discrimination in the labor market. This includes unemployment, low salary, promotion problems, and lack of consideration for managerial position. Gender discrimination in employment remains one of the major challenges that most women face in the present day society. Even though most countries have made significant achievement in empowering women to participate in the country’s development by attaining better education and getting good jobs, women are still discriminated against in employment in many countries the world over. This is particularly so in South Korea where most employers still see women as being inferior to their male counterparts. However, it is high time South Korean employers start according women equal treatment by giving them an equal opportunity as their male counterparts. This is because women too are productive just as men. In addition, the South Korean government needs to promote the involvement of women in employment without bias. The involvement of women in employment will certainly help boost the South Korean economy.

Don Quixote Essay -- English Literature

Anyone who reads Don Quixote for the first time inevitably has some preconceptions about it, beginning with the dictionary def MIGUEL DE CERVANTES SAAVEDRA was born in Alcala de Henares in Spain near Madrid in 1547. Nothing is certainly known about his education, but by the age of twenty-three, he enrolled in the army as a private soldier. He was maimed for life in the battle of Lepanto and was taken captive by the Moors on his way home in 1575. After five years of slavery, he was ransomed; and two or three years later, he returned to Spain. He settled in Madrid and began a moderately successful literary career, in which he wrote poetry, published a pastoral romance, La Galatea(1585), and had some twenty to thirty plays performed without, as he puts it, â€Å"offerings of cucumbers or other throwable matter.† Failing to attain financial success, he obtained an employment in the Government office as a commissioner of food supplies for the Armada expedition. He later became a tax collector, a position that he held until 1597, when he was imprisoned for a shortage in his accounts due to the dishonesty of an associate. The imprisonment on this occasion lasted until the end of the year, and, after a period of obscurity, he issued, in 1605, his masterpiece, El Ingenioso Hidalgo Don Quijote de La Mancha (The Ingenious Hidalgo Don Quixote of La Mancha). Cervantes confesses to having ‘engendered’ Don Quixote in the prison. Its success was great and immediate, and its reputation soon spread beyond Spain. The enthusiastic reception of Part à Ã¢â‚¬   spurred him to unchecked literary activity until his death- a gloriously creative old age in which he completed Don Quixote Part à Ã¢â‚¬  Ãƒ Ã¢â‚¬   (1615), his twelve Exemplary Novels (1613), ... ...’ position, the female characters such as Marcella and Dorothea in Don Quixote speak forcefully in defense of women's rights. Loose in structure and uneven in workmanship, it remains unsurpassed as a masterpiece of witty humor, as a picture of Spanish life, as a gallery of immortal portraits. It has in the highest degree the mark of all great art, the successful combination of the particular and the universal: it is true to the life of the country and age of its production, and true also to general human nature everywhere and always. With reference to the fiction of the Middle Ages, it is a triumphant satire; with reference to modern novels, it is the first and the most widely enjoyed. In its authorÂ’s words: â€Å"It is so conspicuous and void of difficulty that children may handle it, youths may read it, men may understand it, and old men may celebrate it.†

Statement of Educational Goals And Philosophy Essay -- My Philosophy o

Statement of Educational Goals And Philosophy The nature of students is that of an instinctive ability to learn. Students of ages and all grade levels reflect their surroundings and respond according to their interpretation. Naturally it is not only the influence of a classroom that shapes a student but many outside factors that determine students’ goals and abilities; for example, healthy encouragement from parents. Students may find a natural ability to perform in one area of education and with help may fine tune their ability to better their understanding of other areas. Students have a better understanding of education when it is relevant to their needs and everyday life. The nature of knowledge deals with two aspects: that of relative and absolute. From a relative perspective a student’s knowledge is determined by their perception of what surrounds them. Knowledge of any kind has the ability to inspire but if a student does not perceive that knowledge as worthy it may not become part of their educational formation. For instance, a student in art class may perceive different works of a good or bad based on their emotion reaction. On the other hand, the absolute knowledge of how a work of art is created may incorporate specific mathematics and color formulations that are not interpreted by emotion. The combining of relative and absolute knowledge is the result of having a dream and the knowledge to make it come true. Overall, the purpose of public education is to provide knowledge in a manner that all of society may communicate and function on a common level with the intent of raising the standards of future societies. With this purpose in mind, it is the goal to mold... ...nd emotional needs of students, incorporating as much as possible the various other academic subjects. My Education 305 class along with the observation that I completed has helped to bring the reality of students and the relationship of teacher-to-student into focus. Various strategies to maintain discipline within the classroom have been very helpful and given me a better knowledge of age appropriate rewards and punishments. It has also presented to me the most difficult task: motivation. It is not only the way that I see art but to see art through my students eyes and to develop their skill or lack of into something that they at least can appreciate. A teacher is not a magician but a teacher can use many tricks to keep students focused and motivated. Beginning with the first day until the last day it is my goal that every student learns something each day.

‘Of mice and Men’ Analysis Essay

In ‘Of mice and Men’ several characters dream of a different and better life. Why is it not a surprise that the dreams never come true? ‘Of Mice and Men is a novel written by john Steinbeck that features the hopes and aspirations of ordinary people living very simple lives. It features very strong characters each with their own dreams of a different and better life. But of course such dreams only remain dreams because they never do come true. The title ‘of mice and men’ is taken from a poem by a famous Scottish poet Robert Burns that quotes. The beat laid schemes o’ mice and men Gang aft agley (often go wrong) And leave us nought but grief and pain For promised joy! This basically means that it doesn’t matter how much you plan and dream, things very rarely go according to plan, which leaves us longing for promised dreams. John Steinbeck was born in Salinas, California in 1902. This may have been the reason he decided to set the novel ‘Of mice and men’ in the Salinas valleys. It was hard to live in good conditions around the time the book was set (1930-1940) because of the Wall Street crash and the great Depression that followed. It was extremely hard to get a job and if you did get a job, it would be for minimal pay. During the 1930’s there was very bad unemployment, which meant thousands of people never had a job in the USA, so agencies (like the one that Lennie and George got their work cards from, ‘Murray and Ready’s) were set up to end farm workers to where they were needed. Despite these conditions many people believed in the American dream. The theory of the American dream was taken from the 17th centaury and basically mans that in America, it doesn’t matter who you are or where you come from anybody can make it big and be satisfied with what they have achieved. A lot of characters in the novel also had dreams of making it big and owning something good that they have worked hard to accomplish. Lennie Small and George Milton are the main characters and they both had similar dreams although they were very different people in more ways then one. We first get a description of their dream in chapter 1 when George and Lennie were at their campsite about to eat their supper. The conversation about the dream started off when Lennie said to George † tell me- like you done before about the rabbits.† The dream was basically that they wanted their own land where nobody can boss them around and tell them what to do. They also wanted to raise animals such as pig’s cows and chickens † an live of the fatta da lan†. From this dream the to characters Lennie and George both wanted different things. George wanted a place of his own and independence he also wanted security for Lennie but the main thing he wanted is a ranch like the one he lived on as a child. On the other hand the only thing Lennie wants from the dream is to â€Å"tend the rabbits†. At this point of the novel the dream that Lennie and George had was still just a fantasy not reality. This is because George and Lennie did not have much money, like many people who lived around the time of the great Depression. People found it hard to get jobs let alone make a lot of money and they had just run away from another ranch in Weed because of Lennie’s behaviour, so deep down George knew that it was virtually impossible for their dreams to become a reality, until†¦ Candy is an ageing, disabled ranch hand that has been on the ranch for a, long time and when he hears Lennie talking to George about the dream he realises that that was his golden ticket out of the ranch. Candy wants to leave the ranch because he feels that he has no future in the ranch he fears that he might be sacked in the near future because he cannot do his job as good as an able bodied person. Candy realises he has enough money to offer Lennie and George so he could be part of the dream, Lennie and George accepts Candy’s offer and then the dream becomes a reality because George knows a real place they could get. Crooks is a black ranch hand that is discriminated because of his colour. Crooks first gets to know about the dream when Lennie walks into his room, whilst looking for some companionship. When Lennie tells him the dream, at first he did not believe it and he thought it would never happen. But then candy walks into the room and confirms what Lennie was saying at this point candy starts to believe the ream and he offers to join them. Then Curleys’ wife walks in and has an argument with the three men and threatens crooks by saying se could heave him hung, it is after Curleys wife leaves the bunkhouse that crooks decides to withdraw his offer and end his dream. Curley’s wife dream is different from all the other means dreams. When she was younger, a man said that he was a film producer and that when he went he would come back for her and she would be in the movie. She waited for long for the man to send for her but he never did, she thought it her mother hid the letters but I think the man was not a real director; he was just flirting with her. Curley’s wife manages to end all of the dreams she firstly ends crooks dream by telling him that she could get him hung, then she ends everyone else’s dream when she dies because Lennie killed her and George then knows their dreams are over and her dream is over because she dies.

Frank Llyod Wright essays

Frank Llyod Wright essays Frank Lloyd Wright is the most influential architect of modern architecture. Not only is his work famous in America, he has many designs around the world. His unique style may have been influenced by his experiences during his early adulthood. After quitting his first job to try to accomplish his personal goals, he became famous throughout the world. Having many well-known designs, Wrights most known designs are what he calls Prairie Houses, and his home and workplace, Taliesin. Frank Lloyd Wright was born in Richland Center, Wisconsin, on June 8, 1867. He lived with his mom and many aunts and uncles. His dad abandoned the family in 1885 to pursue a music career. Soon after, Wright left to pursue a career of his own. After attending the University of Wisconsin, he traveled to near-by Chicago to start his first job. He worked for a company called Adler and Sullivan. This was an architectural firm that was well known throughout Chicago. There is where Wright first started expressing his ideas. On his own, he made what he called bootleg houses for the companys clients (Blake and Sudler 1). These were kept confidential from the firm, because Wright wanted to receive full credit for his designs. He had a very distinctive style of building that was different from Sullivans common style. Being in a city full of tall buildings, he made houses that had tall walls and received most of its light from skylights. These were made like this to give the clients a sense of privacy among the city living. Some of his most famous bootleg designs are the Unity Church and the Robie House, both located in Chicago. After these designs were found out by Adler and Sullivan, problems had escalated to the point where the company shut down. From there, Wright was able to begin achieving his goals, and make a name for himself as one of the premier architects of his time, or perhaps ...

Erving Goffmans Front Stage and Back Stage Behavior

Erving Goffman's Front Stage and Back Stage Behavior In sociology, the terms front stage and back stage refer to different behaviors that people engage in every day. Developed by the late sociologist Erving Goffman, they form part of the dramaturgical perspective within sociology that uses the metaphor of the theater to explain social interaction. The Presentation of Self in Everyday Life Erving Goffman presented the dramaturgical perspective in the 1959 book The Presentation of Self in Everyday Life. In it, Goffman uses the metaphor of theatrical production to offer a way of understanding human interaction and behavior. He argues that social life is a performance carried out by teams of participants in three places: front stage, back stage, and off stage. The dramaturgical perspective also emphasizes the importance of the setting, or context, in shaping the performance, the role of a persons appearance in social interaction, and the effect the manner of a persons behavior has on the overall performance. Running through this perspective is a recognition that social interaction is influenced by the time and place in which it occurs as well as by the audience present to witness it. It is also determined by the values, norms, beliefs, and common cultural practices of the social group or the locale where it occurs. Front Stage Behavior- the World Is a Stage The idea that people play different roles throughout their daily lives and display different kinds of behavior depending on where they are and the time of day is a familiar one. Most people, consciously or unconsciously, behave somewhat differently as their professional selves vs. their private or intimate selves. According to Goffman, people engage in front stage behavior when they know that others are watching. Front stage behavior reflects internalized norms and expectations for behavior shaped partly by the  setting, the particular role one plays in it, and by ones physical appearance. How people participate in a front stage performance can be highly intentional and purposeful, or it can be habitual or subconscious. Either way, front stage behavior typically follows a routinized and learned social script shaped by cultural norms. Waiting in line for something, boarding a bus and flashing a transit pass, and  exchanging pleasantries about the weekend with colleagues are all examples of highly routinized and scripted front-stage performances. The routines of peoples daily lives- traveling to and from work, shopping, dining out, or going to a cultural exhibit or performance- all fall into the category of front stage behavior. The performances people put on with those around them follow familiar rules and expectations for what they should do and talk about with one another in each setting. People also engage in front stage behavior in less public places such as among colleagues at work and as students in classrooms. Whatever the setting of front stage behavior, people are aware of how others perceive them and what they expect, and this knowledge tells them how to behave. It shapes not just what individuals do and say in social settings but how they dress and style themselves, the consumer items they carry around, and the manner of their behavior (assertive, demure, pleasant, hostile, etc.) These, in turn, shape how others view them, what they expect of them, and how they behave toward them. Put differently, French sociologist Pierre Bourdieu would say that cultural capital is a significant factor both in shaping front stage behavior and how others interpret the meaning of it. Back Stage Behavior- What We Do When No Ones Looking When people engage in back stage behavior, they are free of the expectations and norms that dictate front stage behavior. Given this, people are often more relaxed and comfortable when  back stage; they let their guard down and behave in ways that reflect their uninhibited or true selves. They cast off elements of their appearance required for a front stage performance, such as swapping work clothes for casual clothes and loungewear. They may even change how they speak and comport their bodies or carry themselves. When people are back stage, they often rehearse certain behaviors or interactions and otherwise prepare for upcoming front stage performances. They might practice their smile or handshake, rehearse a presentation or conversation, or prep themselves to look a certain way once in public again. So even back stage, people are aware of norms and expectations, which influence what they think about and do. In private, people behave in ways that they would never in public. However, even peoples back stage lives tend to involve others, such as housemates, partners, and family members. One may not behave as formally with these individuals than standard front stage behavior dictates, but they may not fully let down their guards either. Peoples back stage behavior mirrors the way actors behave in the back stage of a theater, the kitchen within a restaurant, or the employee only areas of retail shops. For the most part, how one behaves front stage significantly differs from an individuals back stage conduct. When someone ignores the expectations for front and back stage behaviors, it may lead to confusion, embarrassment, and even controversy. Imagine if a high school principal showed up to school in her bathrobe and slippers, for example, or used profanity while speaking with colleagues and students. For good reason, the expectations linked to front stage and back stage behavior influence most folks to work pretty hard to keep these two realms remain separate and distinct.

The researcher proceeded to focus on the construction industry in UK. Primary data were generated by way of conducting interviews and giving out questionnaires for both selected industry major players and for randomly selected representatives of the industry market. Research is basically done to gather data in a systematic manner and to interpret such data in the same systematic manner; throughout the process, the purpose of discovering relevant truths should be clearly imprinted in the mind of the researcher (Saunders, Lewis & Thornhill, 2007: 5). The procedures to gather primary data were done to document the sentiments and views of the people in the industry in their various post.

After all, a research paper can only be useful to the extent that it addresses the concerns and needs of its reader. This truth applies to all written works, including industry profiles and management research papers. Researchers must be mindful of and responsive to the concerns and interests of practitioners - the users of the finished reports - for their research output to serve a purpose and become valuable (Bryman & Bell, 2007: 5).

Costume designing for the media - Essay Example Unlike other fashion and costume designers, in most instances those who work within the media industry are not able to work totally in isolation with their own ideas, they cannot just work within their own imagination. There will also be a requirement for the finished costumes produced to have paid regard to the input from a number of other department and individuals within the particular Film, TV and Theatre project. Film, Television and Theatre production companies and organisations consider costume design to be an integral and important part of the process of production. However, each of these individual media elements will impose a different approach and requirement upon the designer. However, as is the case with an actor's poor performance, costume design and construction that falls short of the standard and quality demanded will also have the affect of devaluing the final production.

A further element of this aim is to consider the ethical image the finished costumes should convey to the audiences. Our final aim is to study and identify the different issues and requirements demanded of the designer when working for the Stage and Theatre, as compared with those existing in the Film and Television mediums. Within all of these aims our purpose is also to identify this sector of the industry and its performance in the U.K. as well as the U.S.A.

Journal - Assignment Example A utilitarianism approach will focus on the benefit of the larger group. Here attention will be given to the benefit of many rather than a few and the employees will be treated in a fair manner. Here the greater good of the customers will be considered and managed accordingly. Also, the resources will be used to help for the benefit of many. Finally, in terms of Care Ethics, here the focus is on relationships, vulnerability and empathy. The focus of this approach will be on the emotional aspects of the relationship with little or no attention to more serious elements which can impact the overall growth of the company or the customers. The three kinds of punishments for corporations are clearly, corrective advertising, community service order, and corporate death punishment. Corrective advertising refers to the need for the company to make a public announcement to disclose to the public the mistakes made and the possible issues that arise from the mistakes. Community service order is clearly a means to help make immoral organizations more in sync with the needs of the society and here the punishment is forced until the desired goals are not met. Finally, in terms of corporate death punishment, here the businesses are forced to go out of business by means of revocation of corporate charter. Ethics and morals are the same for every individual and corporation in society. Irrespective of what the organization feels or how the organization responds, it is clearly incorrect and unfair that individuals are treated differently than organizations, especially in the case of unethical or immoral behavior. Hence it is important that the same levels of punishment are given to both individuals as well as

SMBs contribute greatly to the gross domestic product in a country, entrepreneurial skill development, generation of employment and innovation to many developing economies. In light of this, the paper will critically analyze the various sources of financing for small and medium scale businesses Due to the good impact of SMBs in the economy of a country, support schemes and programs have been put forth in institutions by some of the developed and developing countries so as to support them (Prasad, C. 2004). This support includes offering loans, expert counseling on the types of credit so as to avoid credit risk, advice and legal assistance on exports by the government of the United States of America through small business administration. For instance, in the late 80s the Nigerian Government established the Entrepreneur Development Programme through the National Directorate of Employment, the objective of this policy was to reduce unemployment level through providing an opportunity for individuals to acquire entrepreneur skills. Further they would be able to secure loans for themselves so that they can start their own small and medium scale enterprises (Dinesh, 2003). Another case was in Mexico whereby the Mexican Development Fund was established so as to provide an arrangem ent of finance to aid agricultural activities. Despite such efforts, investigations reveal that the SMBs are still facing major challenges. Some of the SMBs cannot easily access funds thus posing a major threat to their existence in terms of growth and survival.

Networking in Telecommunications Term Paper Example | Topics and Well Written Essays - 1250 words

Networking in Telecommunications - Term Paper Example They also provide a range of control and support functions. The channels are the reception and transmission points for the messages and data. The network computers are set so that they ascertain a network connection by use of different media. The network software administers the control and functional activities, assisted by the software in a network. The configuration of telecommunication network has three main components; the user plane, the control plane and the management plane. The control plane carries control data and information, the data plane checks the user traffic in the network and the management plane carries the administration and operation traffic over the network (Gnanasivam, 2006). Telecommunication networks are of three types, these are wide area network, metropolitan area network and local area network. The network that is stretched over a large geographic is known as wide area network (WAN). Metropolitan area network (MAN) covers the area of almost one city or co unty. The communication of computers in an extremely small area is known as local area network (LAN) (Gnanasivam, 2006). ... These networks types are relatively inexpensive and easy to install for small networks. In the Star Topology all devices are connected to a middle device, called a hub. The Star networks are comparatively easy to install & run, but blockage can occur since all data must go through the hub. The ring topology links computers on a distinct circle of cable. Signals travel around the loop in one way and pass through every computer which acts like a repeater to boost up the signal and propel it on to the subsequent computer. The Hybrid Topology Groups of star- organized workstations are linked to a linear bus backbone cable that combines the characteristics of bus and star topologies Wireless Devices are linked by a receiver/transmitter to a unique network interface card that conveys signals between a computer and a server. This transmittance happens with an acceptable transmission range (Mehdi, 2006). Architecture Two primary types of architectures exist; Peer-to-peer (P2P) network Client /server network The peer-to-peer is the simplest type of network. It’s characterized by every computer communicating directly with all other computers. The Client/Server Networks make use of a central computer, known as a Server. The server facilitates communication and resource sharing among other computers on the network. These other computers are known as Clients. The client server network can be compared to a public library in terms of resource sharing. The librarian manages the use of books by patrons; a server manages the use of common resources by clients (Mehdi, 2006). Protocols A protocol is a standard that identifies the layout of data in addition to the rules to be followed during transmission. In simple terms, a computer talks to another

That higher education Essay Example for Free

That higher education Essay With all these guidelines for starters, it would be much possible for new learning program facilitators to come up with possible effective and efficient foundation in online teaching. On the other hand, the â€Å"E-Learning Revolution: How Technology is Driving a New Training Paradigm† by Martyn Sloman shows how much the Internet changed everything especially in the education industry. He says that the â€Å"virtual education has already taken over the systems of traditional learning and as well made great innovations on the learning process of the new generation† (2002, p 23). True, as earlier introduced in chapter one, the existence of virtual learning programs really made great changes on the existence of educational systems in the society. â€Å"Aside from the practicality and other benefits offered by this system of learning, the new generation realizes the importance of time and thus they take the necessary steps needed to finish their degrees through online universities† (Sloman, 2002, p 24). In this way, not only do they finish early, but they also learn how to manage their time wisely. True, the challenges of training people through the use of technological advancements are rather huge. But as Arthur Langer said in his authored book â€Å"IT and Organizational Learning†, â€Å"training using the Internet is really a challenge especially for beginners, but once the effective foundations of learning in traditional classrooms would be integrated with the high-tech effects brought about by the Internet, learning through this innovative design of education could be well considered worth while† (2001, p 14). As an addition to this, Robert Seidel said that Virtual education is indeed becoming a phenomenon already. According to him in his book â€Å"Virtual Reality, Training’s Future? : Perspectives on Virtual Reality and Related Emerging Technologies†, â€Å"Virtual education has already taken full control of many educational institutions there are today. Indeed, even companies are taking their steps in making online trainings a possible way of enriching their employees’ skills for their chosen careers both for individual and company satisfaction† (1997, p 45). Seidel also adds: â€Å"Virtual reality is a simple and natural extension to proceed in learning without boundaries to the virtual environment, as well as being able to completely enjoy the provisions of the virtual world in enriching the industry and strategies used in education† (1997, p 48). Yes, the virtual world had already made a great impact on the ways in which the present generation prefers to learn and earn their college degrees. Indeed, as introduced earlier, the idea of establishing virtual education providers came from the traditional learning aided by distance learning providers even before the development of computers. Naturally, the past forms of distance education were mostly done through correspondence and the use of telecommunication processes. Certainly, technology has obviously revolutionized the ways by which the handling off information through higher level of learning is being processed. Most likely, the integration of technology within the system heightened the capability of the institutions making up the said industry to provide the best possible entities and values available in their service towards the personal advancement of their students.

Analyse Different Chilli Peppers Biology Essay

Analyse Different Chilli Peppers Biology Essay The purpose of this project was to analyse different chilli peppers and hot sauces for their Capsaicin and Dihydrocapsaicin content but concentration was focused more on the analysis of different chillies than sauces. Samples of chillies were refluxed using Ethanol as an extraction solvent and sauces were untrasonicated using Methanol. The extracts were filtered and analysed via Reverse phase HPLC-UV Vis technique. A number of experiments were performed to optimise the method that has been previously used for analysis of chilli peppers. The first experiment conducted was to optimise the duration of reflux time required to obtain a good yield of Capsaicin. Results showed that 1hr is sufficient for the extraction of Capsaicin. A variety of chilli peppers and sauces were analysed so as to ascertain the hottest pepper. In general all samples had good detection. Different parts of chillies were also examined to establish which part contains the highest concentration of Capsaicin and Endoc arp was found to be the hottest part. The reproducibility of the method was also investigated and the sample showed to have a low RSD value. 1. Introduction Next to Jazz music, theres nothing that lifts the spirit and strengthens the soul more than a good bowl of chillies. Harry James (Late American musician) Loved by millions for their hot and sizzling flavours, the chilli peppers have become very popular over the period of time and are being grown in almost in all parts of the world, with Asia being the biggest producer of chillies followed by Mexico and the U.S. In traditional Indian medical system, chilli is used as way of stimulating the digestion and is also believed to be a natural pain killer. The red chilli peppers are also a source of potassium, magnesium and iron and vitamin C. 1.1 Why Are They So Hot? The heat sensation in chillies is caused by a class of chemicals, called the Capsaicinoids. These compounds are found in members of the capsicum family of plants. Capsaicinoids themselves belong to a group called Vanilloids i.e. containing the Vanillyl group [3dchem.com] Figure 1.1 [ en.wikipedia.org] All Capsaicinoids have same functional groups and differ only in length of hydrocarbon chain. The most common of Capsaicinoids compounds is Capsaicin which is the major constituent of chilli peppers and also responsible for their pungent taste. [3d chem.] 1.2 Structure of Capsaicins: Capsaicin figure 1.2.1 Dihydrocapsaicin figure 1.2.2 Nordihydrocapsaicin figure 1.2.3 Homocapsaicin figure 1.2.4 Homodihydrocapsaicin figure 1.2.5 Out of all the Capsaicins, the capsaicin and dihydrocapsaicin are the major constituents of Capsaicinoids (make up 80-90% of capsaicinoids). 1.3 Cis-trans isomerism in Capsaicin [3dchem] Capsaicin can exhibit cis-trans isomerism due to the presence of C=C bond. The double bond prevents the molecule to rotate freely internally, therefore, giving rise to stereo isomers. Cis isomer of the capsaicin is less stable and has higher energy due to steric hindrance. As the methyl groups are in close proximity to each other it causes repulsion between them and hence making it a less stable arrangement due to this added strain. Trans isomer on the contrary has methyl groups further apart and doesnt have any steric hindrance, making it a more stable/low energy arrangement. Therefore, the Capsaicin is always found in the Trans isomer. Figure 1.3.1 [http://www.homesteadcollective.org/mpg/science/majorcrap5.shtml] 1.4 Scoville Scale The scale for measuring the extent of heat in chillies was first invented by an American Chemist Wilbur Lincoln Scoville in 1912. The test he devised is known as the Scoville Organoleptic test in which he had a group of volunteers to taste the chillies on their own and later diluted them with sugar and water until they didnt have any burning sensation left. The resulting dilution factor was called the Scoville heat value of the sample and a number was then assigned to each sample of chilli i.e. Scoville unit, to ascertain the amount of dilution a chilli needs before its hot flavour dies away. [3d.chem] Table 1.4.1 Scoville heat values for Capsaicinoids [g6csy.net] Molecule Strength /Scoville units Capsaicin 16.1 million Dihydrocapsaicin 16.1 million Nordihydrocapsaicin 9.3 million Homocapsaicin 6.9 million Homodihydrocapsaicin 8.1 million The hottest capsaicin found is in the chilli known as Naga Jolokia, grown in India and has Scoville strength of 855,000-105, 0000 units. The Habanero (Mexican chilli) are the runners-up with Scoville rating range of 200,000-300, 0000. g6csy.net As mentioned earlier, in addition to Capsaicins being used as food additives, they have important medicinal benefits and are known as Phytochemicals.[3dchem.com] Due to having pharmaceutical and antioxidant properties, its widely used in anti-flammatory creams and ointments and also used as a counter irritant in surgical dressings and medicines. Moreover, they are also being used in nutritional supplements for pain relief and Arthritis. [cals.ncsu.edu] 1.5. Extraction Methods for Capsaicin Different methods have been devised as a way of extracting capsaicin from chilies and sauces. The simplest technique is to dissolve chilies in a polar solvent and placing the mixture on hot plates for half an hour and then filtering the extract via simple/vacuum filtration and making up with Methanol (100 ml). The other techniques more efficient for extraction are as follows: 1.5.1 Solid Phase Extraction or SPE This technique is particularly useful in extracting capsaicin as it requires pre-treating the sample prior to analysis. This reduces the amount of unwanted components that may interfere with the analysis. The extraction is completed in 4 steps: Conditioning the cartridge: This involves activating the cartridge by passing the sample through it to achieve same conditions with in the cartridge (e.g. to achieve same pH, composition etc as the sample). Retention: The sample is applied to the cartridge and either contaminants are retained and analyte is flushed through the cartridge. Other way used is holding the analyte with in the column and the unwanted components are passed through the column. Rinsing: The cartridge is then rinsed with distilled water to wash off the impurities. Elution: The last step is to elute the sample with appropriate solvent and the extract can then be used for analysis. 1.5.2 Reflux As demonstrated in this project, this method involves refluxing the chilies in methanol for appropriate duration. The reflux time required can be optimized by refluxing samples for different durations to establish the optimum time required by the capsaicin to leach. 1.5.3 Ultrasonication This method can be used for extracting the capsaicin from sauces or capsaicin based creams in short time. The samples are soaked in Ethanol and placed in the ultrasonic bath for half an hour at high temperature. The ultrasonic vibrations release the capsaicin from the samples. 1.5.4 Supercritical fluid extraction or SCFE In this method, the extraction solvent used is a super critical fluid. A super critical fluid (SCF) is a compound above its critical temperature and pressure. Therefore, an SCF is neither a liquid nor a gas. Hence, a super critical fluid has properties similar to liquids i.e. dissolving compounds and also gas like properties e.g. transportation. SCFE also minimizes the matrix components. Due to these capabilities, this method is more efficient and quicker than the other extraction methods. Carbon dioxide and water are the most commonly used SCF. This technique has a variety of applications in food, petrol, and pharmaceutical industries. 1.6. Previous research on Capsaicin Capsaicin has been widely studied and researched by various organisations and institutions but insufficient literature has been published with respect to the analysis of chilli peppers and sauces. In this section, three articles will be discussed as all three papers deal with the analysis of chillies and sauces relevant to this project. The first literature ¹ investigated the concentration of Capsaicin and Dihydrocapsaicin in the Habanero peppers using Super Critical Fluid Extraction method (SCFE). In addition to the analysis of Habanero whole peppers, different parts of chilli were also examined for their Capsaicin content. The Habanero peppers were obtained from two different locations: Cunningham Research station and Bailey Farm (located in North Carolina, US). The peppers were cut into seeds and shells and prior to extraction, the samples from Bailey farms were prepared fresh, oven dried and freeze dried and samples from Cunningham station were prepared in oven and freeze dried states. The whole peppers and seeds/shells samples were extracted using three polar solvents i.e. Methanol, Acetone and Acetonitrile. The Method for SCFE is as follows as stated in the literature: Fresh, oven and freeze dried preparations (0.5g dry weight) were extracted using a biomass: solvent loading of 15% (w/v) based on the initial moisture of the pepper samples/parts. Sample and solvent mixtures were homogenised in 50ml conical glass tubes and placed in a shaking water bath (50 °C). The extracts (2ml each) were then filtered and stored at -20 °C until the analysis. The preliminary work suggested that 1hr is sufficient to get good yield of capsaicin. The extracts were then analysed using Reverse-phased HPLC with UV VIS Detector. The HPLC was equilibrated with capsaicin standards (10, 30,50ppm). The mobile phase composition was isocratic at 60:40 (Acetonitrile: Water with acetic acid (pH 3)). The researchers of this project compared the capsaicin and Dihydrocapsaicin concentrations from both locations. The results showed that the Cunningham stations peppers had higher concentration of capsaicin in comparison with the Bailey farms chillies but the Bailey Farms pepper had higher amount of Dihydrocapsaicin than the Cunninghams. The results suggested that samples that were oven dried and extracted with Acetone gave maximum yields of the Capsaicinoids. This literature also suggested that regardless of the solvent type and preparation state used, seed has the highest amount of capsaicin. The researchers suggested the reason for differences in capsaicin concentration was due to different environments the fruits are cultivated e.g. chemicals used, weather conditions etc. The second literature ² deals with the analysis of three Capsaicinoids i.e. levels of capsaicin, dihydrocapsaicin and nordihydrocapsaicin in different chillies, sauces and arthritis creams via reverse phased HPLC. This research employed a solvent extraction technique which involved addition of ethanol (extraction solvent) to the samples of ground chillies, sauces and creams and placing the samples on hot plates for 30mins. After cooling and filtration, the extracts were transferred into flasks (100ml) and made up to the mark with Ethanol. 5ml was withdrawn from this sample and filtered again into a syringe filter cartridge (0.45 µm pore size). This aliquot was then used for the analysis. A 1000ppm standard stock solution was used to make standard capsaicin solutions ranging from 1-50ppm and ran through HPLC. The mobile phase in this research was made up of ACN, water and phosphoric acid (0.1%).The UV detector was set at 280nm and 205nm to determine samples responses at different wavelengths. In addition, Isocratic and Gradient elution were used. The findings from this journal suggested that Capsaicinoids present in very little concentrations (e.g. 0.5ppm) were detected better at 205nm wavelength using gradient elution rather than Isocratic method. However, results also indicated that for analysis of Capsaicinoids present in greater concentrations, Isocratic elution and UV wavelength at 280nm. The concentrations of the Capsaicinoids were expressed in terms of the Scoville units and the value calculated for the Habanero peppers (150,000) in this experiment was different to the literature value range (200,000-300,000). The researchers attributed this fact to variations in the environment e.g. weather etc. The third literature ³ determined the capsaicin and dihydrocapsaicin content in chilli peppers. The chillies were grounded for 10mins and Acetonitrile (30ml) was added to the crushed peppers and again grounded for 20mins. The solid residue was filtered and an aliquot (1ml) was made up to the mark with Acetonitrile. (in 10 ml flask). The extraction method used in this work was Solid Phase Extraction (SPE): An SPE cartridge was conditioned with Acetonitrile, methanol and water and the capsaicin extract (10ml) was then applied to the cartridge and the analyte was eluted with methanol (4ml) and then again with 1 ml of methanol (containing 1% acetic acid). The analytes were then run through reverse phase HPLC using UV-VIS detector (at 281nm); mobile phase consisted of 77:33 (Methanol: Water). The HPLC was eluted first with the standards so as to obtain the calibration graphs. The Capsaicinoids concentration of different chillies was expressed in Scoville heat units (similar to literature 2). The results showed that Habanero is the hottest amongst all peppers that were analysed i.e. Scoville heat value of 276,000 which corresponded to the literature value range. The least hot pepper was Jalapeno (41,000 Scoville heat units). 1.6.1 Comparison of three papers: The researches have used different techniques to extract the Capsaicinoids i.e. SCFE and SPE. However, the extraction technique used in this project was Reflux (for chillies) and Ultrasonication (for sauces). The extractions were successful and all samples in general were detected which indicates that more than one method can be employed as a way of extracting the Capsaicinoids from chillies and sauces. Various parameters were manipulated as part of method development in literature 2 e.g. Isocratic/gradient elution and different wavelengths. Similarly in Literature 1 three preparation states and three solvents were used to determine what state/solvent gives maximum yield of Capsaicinoids. Literature 1 also suggested that the hottest part with in the chilli is the seeds, however, the findings of this project have shown that the Endocarp contains the highest amount of capsaicin and dihydrocapsaicin. This is indicative of the fact that the amount of Capsaicinoids can vary even with in d ifferent parts of chilli. However, all researches discussed as well as this project has used polar solvents to extract the analytes and the analytical technique used was reverse phase HPLC which indicates its usefulness in the capsaicin analysis in particular. Once an analyte of interest has been extracted, it can be analysed by a process called Chromatography. 1.7 Chromatography The word Chromatography originates from Greek; Chroma means colour and graphein implies to write. [Skoog West Analytical Chem 7th Edition page 646] The history of this separative technique dates back to early twentieth century when it was developed by a Russian Botanist Mikhail Tswett in 1903[D kealy Instant notes]. He used this method for separation of various plant pigments and samples were passed through a calcium carbonate column. The separated analytes were identified as they left coloured bands on the column. [Skoog West Ana Chem 7th Page 646]. Since its invention by the Russian Scientist, this method has been modified and developed in many forms to give quantitative (amount of the analyte present) and qualitative analysis (identification of the unknowns) of complex mixtures. [d.Kealey instant notes page 119]. Separation in Chromatography is achieved by passing the sample mixture through the stationary phase by continuous flow of a mobile phase. This process is known as Elution. Hence, the chromatographic separation depends on the differences in the distribution ratios of the sample components between the stationary and mobile phase. Therefore, this capability of an analyte to migrate at different rates in both phases gives separation over a period of time and distance travelled. [D Kealey page 120] Kx= Cs/Cm, where kx is the equilibrium partition coefficient and Cs and Cm are molar concentrations of analyte in mobile and stationary phase. There are two types of Chromatography techniques: Year 2 notes page 25-26 1.7.1 Planar Chromatography In this method, the stationary phase is composed of a flat bed of material which is made up of an adsorbed layer distributed evenly over a sheet of glass, plastic or Aluminum (known as Thin Layer Chromatography or TLC) Paper Chromatography is also another type of Planar Chromatography in which the stationary phase is a sheet of cellulose material. 1.7.2 Column Chromatography In this method, the stationary phase is a glass or metal column on to which the stationary phase is tightly packed onto a column where separation takes place. Examples of Column chromatography are Gas Chromatography, High Performance Liquid Chromatography etc. 1.7.3 Chromatogram The plot of detector response Vs elution time is known as the Chromatogram. [Year 2 notes page 25]. Figure 1.7.3.1 [http://www.clu-in.org/characterization/technologies/images/retention.gif] 1.7.4 Retention time In the above figure is a typical chromatogram and term tr is the time taken by the analyte to elute the column, known as Retention time. [year 2 notes page 28] 1.7.4 Dead time [d Kealey page 121] Indicated as tm in the fig is referred to the dead time this is defined as the retention time required by the non retained species (i.e. mobile phase molecule) to pass through the column. A good Chromatogram should have well defined peaks having correct shape and symmetry (i.e. Gaussian shape), eluted in reasonable retention time (tr not too long or too short) and should be separated from the extraneous peaks. [Year 2 notes page 29] 1.8 Describing a Chromatogram There are four parameters used in chromatography that evaluate the quality of a chromatogram. These are: 1.8.1 The Capacity Factor, K It is the amount of mobile phase required to elute a particular peak. The K is calculated for the first and the last peak. This factor is particularly useful when establishing the best mobile phase composition in the HPLC. K can be calculated as following: K= (tr-tm)/tm where tr is the retention time and tm is the dead time. A Chromatogram having well separated peaks in good retention time will have K values between 2-8. 1.8.2 The Selectivity Factor, ÃŽÂ ± This is the ability of a system to separate two analytes (A and B) and is calculated by: ÃŽÂ ±= trb tm/ tra- tm, where trb and tra are the retention times of analytes A and B. A system where peaks are clearly separated has a value of ÃŽÂ ± > 1 1.8.3 The Resolution factor, Rs This determines the ability of a system to resolve two peaks that elute very close to each other. And can be calculated by: Rs = 2 (trb-tra)/Wa+ Wb where tra and trb are retention times and Wa and Wb are the peak widths of analyte A and B. The value of Rs > 1.5 for a good quality chromatogram. 1.8.4 The Efficiency Factor [ D kealey page 126-127] When separation takes place in a column, the chromatographic separation can be evaluated by the resolution factor, Rs or the efficiency factor. The efficiency is defined as the number of theoretical plates in a column. This factor evaluates the extent of band broadening of the analyte peaks. Increasing the number of plates and reducing their heights gives better efficiency and vice versa. The plate height can be calculated using: H= L/N where L is the length of the column (in mm usually) and N is the number of plates. The efficiency factor N is calculated by: N= 16 (tr/W) ² for a peak with a good baseline N= 5.54 (tr/W1/2) ² for a peak with a poor baseline and W1/2 is the width at half the maximum height of the peak. (year 2 notes 42-43) 1.8.5 Band Broadening As an analyte passes down a column, the peaks become shorter and broader due to various factors that cause band broadening. The Van Deemter Equation explains the reason for the band broadening: H= A+ (B/u) + Cu where H is the plate height and u is the linear velocity of the mobile phase. Other variables in the equation are explained below: A- Eddy Diffusion: As the mobile phase carries the sample components through the stationary phase, some components pass through the column in a straight line whilst other may that are retained longer by the stationary phase may deviate from the straight path and cause the peaks or bands to be broader. If evenly sized particles are used for packing the stationary phase, then the Eddy diffusion can be minimized. B- Longitudinal Diffusion: If the mobile phase is travelling at low velocities, then the analyte will spend more time in the column as analytes diffuse into the mobile phase. This longitudinal diffusion contributes towards peak broadening and can be minimized by an increasing the flow rate of the mobile phase. The increased velocity will reduce the retention time resulting in decreased effects caused by this phenomenon. [Veronica HPlc page 17-19] C-Mass transfer: As discussed earlier in this section, the separation depends on the ability of the analyte to distribute itself between the stationary and mobile phase. As the mobile phase is constantly flowing, the true equilibrium distribution of the analyte is never established. This leads to increased retention times and thus resulting in peak broadening. [d kealey page 124] 5. High Performance Liquid Chromatography or HPLC HPLC is a form of liquid chromatography which provides both qualitative and quantitative information about complex mixture samples in short time. The stationary phase in this technique is made up of very small fine particles and the sample is forced through the column by mobile phase solvents under high pressure, hence also bearing the name High Pressure Liquid Chromatography. [page 1 Veronica HPLC]. 5.1 Mobile phase in HPLC The main requirement for this technique is that the analyte must be soluble in the mobile phase as the mobile phase carries the sample mixture through the column where separation takes place. Therefore, if the analyte interacts with the mobile strongly, it will elute the column faster, leading to shorter retention times. [page 66 Chromatographic separations]. The mobile phase can either be a single solvent or different solvents combinations may be used. After suitable mobile phase has been chosen, the system can be set at isocratic or gradient conditions. In Isocratic conditions, the chosen ratio of solvents remains constant throughout the analysis e.g. in this project Isocratic mobile phase used for analysis. In contrast, the gradient mobile phase can be changed over the period of time. [Year 2 notes ]. 1.9 Stationary phase in HPLC The stationary phase in HPLC consists of a solid made out of micro porous material packed into the metal column. Silicas or modified Silicas with nonpolar organic groups attached are commonly used as column packing material. Out of all stationary phases used in HPLC, Octadecyl silica known as ODS or C18 is most extensively used due to its ability to separate the analyte components with high, intermediate and low polarities. Other stationary phases used in HPLC are Aminopropyl, Nitile, Sulphonic acid, quaternary Amines etc [d. kealey 159-161] Elution in HPLC is carried out by determining the extent of interactions of the analyte with the stationary and mobile phases. The degree of separation of the sample components depend on their migration rates and distribution ratios in both phases. 1.9.1 Normal and Reverse phase HPLC In normal phase HPLC (adsorption chromatography), the stationary phase is more polar than the mobile phase which is weakly polar. The separations are based on the relative polarities of the sample components. For instance, if species A is more polar than the species B, A will have strong affinity for the stationary phase and will be held in the column longer. This will result in species A having long retention time compared to B. Thus, in normal phase HPLC, least polar analyte elutes first. In Reverse phase HPLC (bonded phase chromatography), the stationary phase in non polar and the mobile phase solvents used are polar. This phase is governed by the hydrophilic and hydrophobic properties of the analytes. Most polar analyte elutes first and vice versa. As Capsaicinoids are relatively non polar, therefore, if the mobile phase polarity in reverse phase is increased then the analyte will have stronger affinity for the stationary phase and therefore will spend more time in the column, leading to long retention times. The mobile phase solvents used in Reverse phase HPLC are water or aqueous buffer with an organic solvent. The use of protons in mobile phase composition improves the peak shape and travels in column quickly.

Most commonly used pumps are reciprocating pumps. The pumps used should be free of corrosion, must supply an accurate and controlled flow rate and should be pulse free. The HPLC solvents for mobile phase must be degassed to ensure they are pure and free of any contaminants. This is done by passing an inter gas through the solvent reservoir in vacuum degasser. Injector: The sample is injected through syringe into the injector port. The injection system must not interrupt the flow of mobile phase and should deliver sample into the column in small volumes (5-500 µL). Column: Most commonly used HPLC column is 25cm in length, internal diameter of 4-6mm and particle size of 5 µm. 1.9.3 Detectors in HPLC When the sample components elute the column at different rates, they pass through the detector, and the information form the detector is then displayed in the form of a chromatogram. 1.9.4 UV-Vis Detector The detector is set at a specific wavelength which will be absorbed by the analyte. The degree of absorbance of UV radiation by the analyte is proportional to its concentration. (Beer Lambert law) 1.9.5 Diode array Detector or DAD The Diode Array detector is a type of UV Vis Detector [D Kealey page 162]. When the sample reaches the sensor cells, UV radiation is shone on the analyte. The light source mostly used is a Deuterium lamp. After light passes through the cell, its dispersed onto the photosensitive diodes via diffraction grating or quartz prism. Every diode in the array detects different wavelengths. The measure of differences in extent of absorbance at different wavelengths by the sample components results in their identification and also gives information about the concentration of the analytes. [http://www.chromatography-online.org/topics/diode/array.html] Other detectors used in HPLC are Fluorescence, refractive index, electrochemical detectors etc. [d Kealey 163-165] Figure 1.9.5.1 Experimental Method This project was performed in four different experiments. In all experiments, the methods for extracting the capsaicin from chilli peppers and sauces were the same i.e. reflux and Ultrasonication. However, different masses of chilli peppers, their individual parts were used and solvent volumes were taken in these experiments. (see results) 2.1.1 Preparation of chilli samples and extraction Several chillies were cut into small pieces and weighed into a 250 mL round bottom flasks. Ethanol (75 ml) was then added to chillies. A condenser (fitted with rubber tubing to the water tap) was fixed to the round bottom flask and solution was placed on isomantle (set at 80 °C) and refluxed in fume cupboard. After cooling off, extract was filtered into 100ml flask and made up to the mark with ethanol. A 5ml aliquot was withdrawn into 1.8ml sample vial using a 0.45 µm syringe filter. These aliquots were then analysed through HPLC. 2.1.2 Preparation of chilli sauces and extraction The hot sauces were prepared by dilution of sauce (2g) with ethanol (15ml) in beakers and solutions were places in ultrasonic bath (set at 60 °C) for 30 minutes. The extracts were filtered in the same way as chillies i.e. using 0.45 µl syringe and transferred to 20ml volumetric flasks and bringing up to the mark with methanol. The equipment used was white tiles, knife, weighing boat and weighing scale. 2.1.3 Preparation of glassware In analytical experiments, its of prime importance to ensure the glassware used is clean. Therefore, the glassware used in this project was washed first with deionised water and then with the solvents used. 2.1.4 Preparation of standards for Calibration The standard solutions were prepared from 200ppm stock solution directly into sample vials. Eppendorf pipette was used for accuracy and 0, 20, 40, 60, 80, 100 ppm standards were made with HPLC standard Methanol. Concentration/ppm Volume of 200ppm Capsaicin/ ÃŽÂ ¼L Volume of methanol/ÃŽÂ ¼L 0 0 1000 20 100 900 40 200 800 60 300 700 80 400 600 100 500 500 2.2 HPLC The HPLC used in the laboratory was Agilent 1100 Series Column- ODS hypersil UV VIS Detector- G1315B Diode array detector (set at 280nm) Flow rate- 1.3 ml/min Windows XP CPU Mobile phase- Isocratic at 65:35 Acetonitrile (2% acetic acid): water Particle size- 5 µm, Column dimension- 250mm x 4.6mm 2.3 Determining ÃŽÂ »max for UV- Vis detector The ÃŽÂ »max for the detector was determined by placing methanol blank in UV spectrometer (Perkin Elmer with lambda 40) to calibrate it. After calibration, a 100ppm capsaicin standard was placed in the spectrometer and a graph was obtained with the optimum wavelength (see Appendix 1). This was 280.40nm and the HPLC detector was set at this wavelength. 2.4 Determining optimum mobile phase composition (see Appendix 2) The mobile phase was altered to different ratios to establish what ratio gives the best separation and reasonable retention times (less than 7 minutes). The 80:20 ratio (MeCn: water) gave shorter retention time but the peaks were eluted closer to each other. The 70:30 ratio showed good retention time but peaks were still closer to each other. 50:50 ratio gave long retention time and 60:40 ratio gave good separation but retention time was longer. Therefore ratio of 65:35 was used as this gave the best retention time and separati

A Comparison of Primate and Dolphin Intelligence Essay -- Biology Essa

A Comparison of Primate and Dolphin Intelligence as a Metaphor for the Validity of Comparative Studies of Intelligence Primates and cetacean have been considered by some to be extremely intelligent creatures, second only to humans. Their exalted status in the animal kingdom has lead to their involvement in many experiments which hope to gain a better understanding of the basis of human intelligence. These experiments coupled with analysis of primate and cetaceans brain structure has lead to many theories as to the development of intelligence as a trait. Although these theories seem to be sound, there is some controversy over the degree to which non-human studies can be used to infer about the structure of human intelligence. By many of the physical methods of comparing intelligence, such as measuring the brain size to body size ratio, cetacean surpass non-human primates and even rival human beings. For example dolphins have a cerebral cortex which is about 40% larger a human being's. Their cortex is also stratified in much the same way as a humans(1). The frontal lobe of dolphins is also developed to a level comparable to humans. In addition the parietal lobe of dolphins which "makes sense of the senses" is larger than the human parietal and frontal lobes combined (1). The similarities do not end there, most cetaceans have large and well developed temporal lobes which contain sections equivalent to Broca's and Wernicke's areas in humans (1). Another major difference between primate and cetacean brains is that the primate brain favors the motor cortex, while "the cetaceans greatly favor the sensory region (and are not very balanced at all between the two)" (1). In the final measure of brain complexity, neural density ... ...hat the have a similar brain structure; behavior is way to species specific to be studied without the common thread of the brain. The study of non-human primates and dolphins has lead to many profound questions as to the nature of intelligence. And thought the answers provided to date have been disputed, the questions are not any less worth of being asked. But in order to get beyond the disputes, researchers must be willing to shed there antrocentric view of intelligence and accept that it is an trait which can evolve like any other trait. When this is done it may be finally possible to recognize the remarkable abilities that some many people seem to find in animals as evidence of animal intelligence not lesser human intelligence.

Computerization at Work :: Technology Computers Essays

Computerization at Work Work is a major component of many people's lives. Wage income is the primary way that most people between the ages of 22 and 65 obtain money for food, housing, clothing, transportation, and so on. The United States' population is about 260,000,000, and well over 110,000,000 work for a living. So, major changes in the nature of work - the number of jobs, the nature of jobs, career opportunities, job content, social relationships at work, working conditions of various kinds - affect a significant segment of society. Computer-based systems are organized to enhance the quality of working life for clerks, administrative staff, professionals, and managers. Computerization has touched more people more visibly in their work than in any other kind of setting-home, schools, churches, banking, and so on. Workplaces are good places to examine how the dreams and dilemmas of computerization really work out for large numbers of people under an immense variety of social and technical conditions. Office work has always involved keeping records. In the early twentieth century, the technologies and organization of office work underwent substantial change. Firms began to adopt telephones and typewriters, both of which had been recently invented. By the 1930s and 1940s, many manufactures devised electromechanical machines to help manipulate, sort, and tally specialized paper records automatically. Some of the more expensive pieces of equipment, such as specialized card-accounting machines, were much more affordable and justifiable in organizations that centralize their key office activities. Business such as insurance companies and banks, along with public agencies, adopted computer-based information systems on a large scale in the 1960s. Many of the early digital computer systems replaced electromechanical paper-card systems. The earliest systems were designed for batch operation. Clerks filled in paper forms with information about a firm's clients, and the forms were then perio dically sent to a special group of keypunchers to translate the data onto cardboard card. These card each stored one line of data, up to eighty characters. They were punched with a series of holes for each character or number. Keypunch machines were clanky devices with a typewriter-style keyboard, a bin for storing blank card, and a holder for the card being punched. There was no simple way for a keypunch operator to correct an error. Cards containing errors had to be completely repunched. The punched cards were then taken to a data-processing department for a weekly or monthly run, during which time records were updated and reports were produced.

Pakistan Textile Industry

Compiled By: Mirza Rohail B http://economicpakistan. wordpress. com/2008/02/06/textile-industry/ Historically, Pakistan’s textile industry and clothing sector has always been a major contributor to the foreign exchange earner and still contributes about 55% to the total export proceeds. The Economist reports that Pakistan is the 4th largest producer of cotton in the world and the 6th largest importer of raw cotton, the 3rd largest consumer of cotton, and the 1st largest exporter of cotton yarn. Over 1. 3 million farmers, out of total of 5 million are involved in cultivation of this crop. Textile exports in 1999 were $5. 2 billion and rose to become $10. 5 billion by 2007. Textile exports managed to increase at a very decent growth of 16% in 2006. In the period July 2007 – June 2008, textile exports were US$ 10. 62 Billion. Textile exports share in total export of Pakistan has declined from 67% in 1997 to 55% in 2008, as exports of other non-textile sectors grew. UN reports 102 countries import textile and apparel products and 104 countries export these products. Global trade in textile and apparel products account for an approximately $440 billion. Pakistan is bogged down in the 5% textile requirement of the world, by dedicating 62% of its GDP share for textile. An anti-dumping of 5. 8% has been imposed by the European Union, which has put Pakistan in a desperate position to match competitiveness posed by Bangladesh, India, China, Sri-Lanka and Vietnam. The top buyers of Pakistani textile goods are: USA, EU, Gulf region, UK, Hong Kong, Japan, Korea, Saudi Arabia, Italy, Turkey, Germany, Norway, France, Canada, Sweden, Australia, etc. Government vision 2005-2010 To overcome global competition, the Pakistani government in 2006 approved a â€Å"Technology-based Industrial vision and strategy for socio-economic† which called for technology up-gradation, human resource development, and establishment of a fully integrated chemical industry in the country. Investment Policy & Incentives for Vision 2005-2010:  · Whole of textile sector is included in list of value added industries.  · 5% custom duty on imported machinery if not manufactured locally.  · Tax relief: Initial Depreciation allowance (IDA) at 50% of machinery & equipment cost. Export plan 2006-13 seeks to increase textile and garment’s sector exports to $24. 36 billion. There is a need to engage young qualified generation as roving ambassadors of marketing caliber, diplomacy and professional approach. Pakistan commerce intelligence may chalk out plans to reach every region bloc with in-depth study of regional trade bloc. 2009-10 Performance The share of textile exports in total exports of the country shrunk to 55 percent so far in the current financial year from well above 60 percent in the past years. As the overall export volume remained stagnant in the first seven months of the current financial year, the shrinking share of textile goods in exports has been adversely impacting the export sector. During July-January 2009-10, total exports came to $10. 870 billion as against $10. 820 billion in the corresponding period of last year. In the months under review, textile export proceeds totalled to $5. 981 billion over $5. 849 billion in the same months of previous year. 2008-09 Performance According to data by Federal Bureau of Statistics, Textile exports during the first eight months of current financial registered negative growth of 5. 6% as against the exports recorded corresponding period of the last financial year. Exports during July-February (2008-09) totaled $ 6. 47 billion against the exports of $6. 85 billion recorded during July-February (2007-08). [Link] During the time under review, the highest negative growth of 51. 24 percent was recorded in the exports of yarn (other than cotton yarn) while exports of art, silk and synthetic textile were decreased by 23. 5 percent. Similarly, exports of cotton yarn declined by 15. 28 percent, cotton (carded or combed) by 13. 81 percent, knitwear by 2. 66 percent, bed wear by 10. 44 percent, tents, canvas and tarpaulin by 21. 18 percent, readymade garments by 12. 43 percent, made up articles by 0. 3 percent while the exports of other textile materials declined by 15. 28 percent during the period. However, the exports of raw cotton witnessed increase of 154. 5 percent during the time under review while exports of cotton cloth increase by 5. 57 percent and towels by 10. 02 percent. Textile Machinery Imports According to official statistics released by Federal Bureau of Statistics (FBS), country’s total textile machinery imports declined to $438. 270 million during the last fiscal year of 2008, over the import of $502. 898 million in fiscal year 2007, depicting a decrease of $64. 6 million in the fiscal year 2008. [Link] Imports of textile machinery in the month of June 2008 alone also indicated a decline of 22 percent, as compared to the month June 2007. In June 2008, the industrialists and textile manufacturers have imported textile machinery worth $32. 101 million as compared to $41. 7 million during the corresponding period fiscal year 2007, which depicted a decrease of $9 million only in June 2008. Industry – Spindles, Rotors and Looms In 1999-00: Units 443 and Spindles 8,477,000 and Rotors 149,780 and Looms 9944. In 2003-04: Units 456 and Spindles 9,590,000 and Rotors 146,640 and Looms 10,646. In 2005-06: Units 461 and Spindles 10,437,000 and Rotors 155,104 and Looms 8747. In 2006-07: Mills 567 and Spindles 11,809,000 and Rotors —– and Looms 9000. The least developed sector is weaving which mostly comprises of smaller, fragmented and inefficient units. These units are called inefficient as they mostly use power looms, which are capable of producing narrower width fabric s and mostly use coarse counts of yarn. Therefore, the quality is much inferior to fabrics produced on shuttle-less looms. For decades, the government continued to charge import duty at fabulous rates on shuttle-less looms. Income from power looms was tax exempt but income of units using shuttle-less looms was taxable. The knitwear segment of Pakistan has always focused on achieving higher volume rather than concentrating on quality, price and terms of delivery. A spinning unit of 14,400 spindles employs around 100 persons. Global financial crisis As the economies in the US and Europe slow down, Pakistan’s key exports of textiles and leather products are experiencing a slowdown in growth as well. According to APTMA, textile exports have declined by about 20 percent in 2008. The industry is bracing for more trouble ahead with continuing crises of electricity and gas, international market access, global economic slow-down, and adverse travel advisories. Pakistan’s share of the US textile market is dropping. China tops the US market with a share of 36 per cent followed by Bangladesh 21 per cent, India 18 per cent, Morocco 19 per cent and Pakistan 13 per cent. South Korea has lost 20 per cent of the US market. In the European market, China tops again with a share of 29 per cent, Vietnam 28 per cent, India 19 per cent and Pakistan only 1. 5 per cent while the Philippines had lost 11 per cent of the market. WestPoint Stevens and Dan River were two American companies which were negotiating a $200 million deal with a Karachi-based textile group in Karachi. It has been put on halt. Setbacks for Pakistan Textile Industry  · Recently, the government has also abolished research and development (RandD) support program for the textile sector from July 1 2008. [Link]  · The Pakistani government had recently proposed to implement 18 percent Value Added Tax (VAT) on the textile sector in the upcoming budget. [Link]  · Decline in the machinery imports, is also due to the enhanced interest rates on loans, which have not been decreased by the new State Bank governor. Recent substantial hike in gas tariff also hurt the growth of the textile industry.

Case Study One Solved Ethics Essay

Integrity Your son, Mark, has been working â€Å"night and day† on a major contract for his company over the past six months. To substantiate his company’s viability, Mark had to divulge certain private corporate information to Jim—the prospective customer. He gave out the private information during the closing phase of the contract—only after it had been clearly implied the contract would be his. Unfortunately, the contract did not materialize. Jim found a better deal. Mark is really upset by Jim’s lack of business ethics. He is also a little worried about keeping his job. He now believes that many of the statements made throughout the contract discussions and negotiations were false and deliberately misleading. Question OK dad/mom, your son Mark needs some advice. Write him a one-page letter. How should he have handled this situation and what should he do now? Bring your answer to week 2. Dear son I feel very good that you are seeking help of your parents .Being a mother I feel that you should try to keep your professional life a better one and not to reveal any information about the company and the policies to any of the customers as the information and the things of business are very sensitive and may cause a great harm if the person you are sharing with is not loyal. According to me you should have read the policies and the contract before signing any of the document and you should try to avoid such a mistake again in life. With regard to this I must say you should try to consult a lawyer or any law  suit if you find any problem with the Jim. And if you feel that Jim is not doing well and is not standing on the contract made then you should try to avoid revealing secretive information to any of the person and should read the policies and make a suitable contract with only trust worthy person and if you feel like you are cheated or any kind of loss has happened then you must sue or file a case against that person. But the ethics and the last things that comes to my mind is the ethic of honesty and a reliability. You should try to avoid such mistakes in future so that your hard work will become fruitful and you will become a successful business personality.
