Major regions of the brain and their functions on behavior Essay

The brain is a complex structure that is divided into specialized parts or regions that perform specialized function. The importance of specialization and brain parts division is not only in brain processing information and generating responses, but the specific impact on behavior of an individual generated by each specialized part. In this regard, the brain has three main regions: cerebral cortex, limbic system and the brain stem (Charles, 2002). The brain stem is the most primitive part of the brain that is located at the joint where the spinal cord enters the brain (Charles, 2002). This part of the brain contains such sub-parts as reticular activity system, medulla and the Pons. The main function of this part of the brain is for autonomic functions deemed as necessary for survival such as health, food, shelter and security seeking behaviors. For instance, when a person falls ill, the brain stem triggers off the course of action to seek medication or health care, thus such an individual shall move towards the hospital premises than to any other direction of food or security. The cerebral cortex is brain region that is on outer part that covers the brain (Charles, 2002). By virtue of covering the brain, the cerebral cortex is considered as the largest part of the brain. The behavioral function of the cerebral cortex involves higher cognitive processes such as memory process that enhances language, thought and learning. Therefore, behaviors such as performance in academic work, ability to retain and remember, verbal fluency and speech development are controlled and generated by the cerebral cortex. Limbic system (Charles, 2002) is the third region of the brain with structures such as hippocampus, thalamus, amygdale and hypothalamus. This part of the brain is responsible for emotional related behaviors of individuals such as motivation, memory functions, and physiological functions. For instance, amygdale is responsible for behaviors such as anger, fear and aggression. The hippocampus sub-structure involves the functions of memory such as information coding and processing into short term and long term memories. Hypothalamus is responsible for emotional behaviors such as hunger, sexual feelings, thirsty and reproduction behaviors. The sensory process as these scenarios unfolds The process and action of hitting the ball produces a cracking sound that travels through air to the ears as a sound sensory organ. The sound message is received and conveyed by ears sensory nerves to the central nervous system (CNS). The central nervous system in return initiates nerve impulse to send the message to the brain. In the brain the thalamus located within the limbic system received the message through sensory receptors found in peripheral nervous system and then forwards the message to the cerebral cortex for analysis and interpretation and then generate feedback message to the sight sensory organs (Albert, 2002). After interpretation of the of the ball sound in the brain by the cerebral cortex, the message is generated back through the same avenue that to the thalamus that will send impulse to the sight sensory organ: eye. The eyes muscles shall be involved in a reflex action to adjust and pay attention to the ball that has been hit. Therefore, ball movement is traced by the eye. However, since the eye does not have the capacity to catch the ball apart from observing it; the sight sensory nerves within the eyes send a message to the brain to prepare necessary mechanism to catch the ball (Albert, 2002). Once the message has been generated by the sight sensory nerves to the brain, the brain through thalamus receives the message through the sensory receptors found in peripheral nervous system and then forwards the message to the cerebral cortex for analysis and interpretation. After analysis and interpretation, the cerebral cortex sends back the message to thalamus which in turn stimulates the concerned organs through responsible neurotransmitters to prepare muscle action to catch the ball as it land. The timing of the ball is entirely an initiative and is dependant on cognitive abilities of the individuals (Albert, 2002). Reference Albert, B A.

American Core Cultural Values

I grew up in a very liberated yet bonded family. Mom and Dad are working, my siblings have their own worlds, and I am busy with school. However, we still find time to sit and relax and chat every night, and know the latest in each and everyone of us. I am also raised in a wonderful community which I call my second home. I met a bunch of people, of different tongue and color, whom I consider friends; and neighbors, who burst out of their houses ready to greet you with a warm smile.For me, everyday is a new day – learning new things, getting excited with minute things, seeing beauty in the world. Since then and now, America has changed a lot – it has dramatically transformed from something so simple, into a great nation of complexity. This often make me stand, gaze in oblivion and ponder – of the diverse American values, a hundred or so cultural diffusion if not acculturation, countless experiences, rich and unique history, are there any left native to us?Are there values that we can proudly call â€Å"heraldic† and â€Å"ours† since time immemorial? I discover many, but for the purpose of this paper, I will focus on four American core values I found significant and got to live with since I was born – Individualism, Time Management, Equal Opportunity and the so-gone issue on Racism. At a very young age, I was trained by my workaholic parents to stand on my own feet which simply began with learning to dress myself alone, to tie my shoe lace, to prepare my school bag and cook my own breakfast.I was trained to be responsible with my actions, words and decisions that if failures arose, I have no one to blame but myself. I grew up having sense of being an individual – independent, resourceful, hardworking. I tend to be self-reliant, not giving myself much attachment to other people except for social purposes. I had envision myself to be this or that person, or to have this or that belongings and I strive (and is still s triving) to reach the goal that I have designed and formulated.Like most of my co-citizen, I want to be known not as the son of Paul Miller or a brother of Louise Brown – I want to be known as a separate, unattached entity named Robert Walden. Like the Africans, the Americans live with the value of Individualism – a concept which stresses human independence and the importance of individual liberty in terms of morality, politics, economics and society. It opposes the general concepts of communism, holism, socialism and the likes which view communal relationship as more important than individuality. Being self-reliant, Americans believe in the ability of the â€Å"self.† One is responsible for himself, and most likely, you won't find a person who will generally lend a hand to you, because as an individual, with determination and own way of thinking, you are expected to seek solution or find someone else who can aid you. Americans also have a very strict work ethic . As most of us notice, American businesses are most likely to stick to deadlines and seldom would it be extended for an individual's sake. Often, when an employee arrived late, the employer wouldn't scrutinize the former since he has nothing to do with it and the employee is responsible for his tardiness.Also, businessmen strongly value the concept of â€Å"healthy† competition. Americans believe that competition brings out the best in an individual, and in this case, in a business. Having a â€Å"free market† economic system, companies are strongly encouraged to compete resulting to the lowering of product prices while increasing its quality, thus, the concept of â€Å"free enterprise. † Not only in the workplace is competition highly visible – it is as well a common value at school. Students also do compete – they study well, participate in class activities, etc.Seeing other students doing the same way make them strive even harder so they would end up being the best among the rest. If schools award and honor students who have worked harder than the others, companies also reward those who showed industry and dedication, especially those employees who achieved the greatest goals. The state promotes liberty and equality, not just of the individual but of all aspects of life – from the family to the society, from local government to the entire city, from a single entity to a nation.Liberty is defined as the condition that provides an individual to act according to his own will, giving him the freedom from external compulsion. This again falls to the initial value of individualism – one being solely responsible for himself. The combination of these two ideals refines an American to act and work efficiently and in the most practical way. From liberty resurface the concept of equality. Americans regard â€Å"equality† as significant, if not, vital for the nation's survival, and the citizens' harmonious relati onship. To quote paragraph 2 of the US Declaration of Independence:We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed (US Congress, 1776). But the pursuit of equality in the United States took many years of efforts and struggles from different social groups – innumerable bullets soared in the air, blood flooded the countryside, protests and social movements impaired the hearing of those who wouldn't listen.Racism has, ever since the coming of the â€Å"colored† people, been the most debatable and undying issue in American history. The entry of the Blacks during the â€Å"Slave Trade† commenced the years of discrimination since they came primarily to work in the plantation, construc tion sites and other brawn activities that require strength and endurance. As workers, they were viewed lowly by the society – as inferior to their professional office activities. But as the society slowly becoming liberated in ideas and open to changes and transformation, so are the people's behavior and attitude towards their so called â€Å"other people. †This understanding resulted to the dawn of the concept â€Å"equal opportunity,† another significant American value that has been continuously advocated by the U. S. Government. Equal opportunity is said to be synonymous with racial harmony – the elimination of all forms of violence and discrimination between different races, thus, giving everybody equal access to politics, economy, spirituality, and other common necessities and needs. One way to promote such ideal is by creating and passing laws that prohibits, for instance, job discrimination and elevates the international understanding of human rig hts and human rights violations.Some laws and provisions against job discrimination are discussed and incorporated in the Civil Rights Act of 1964; the Age Discrimination in Employment Act of 1967; the Americans with Disabilities Act of 1990; the Rehabilitation Act of 1973; and Civil Rights Act of 1991. The United States Equal Employment Opportunity Commission (or EEOC) enforces these and other laws related to the protection of people from job alienation, particularly those of non-American race. Before, I found it really difficult to befriend other nationalities, as personally, I have no idea on how to approach them in utmost respect.However, feeling at ease in a diverse and complex environment that I grew up with gave me the courage (and in some way, disciplined me) to act normally with and treat other races in a manner that I would want them to treat me. And as such, it is now a taboo to see a White man cursing and pouncing on a Black man simply because of the latter's color. Last ly, what I regard as among the most important values of the Americans is their reverence with time. Cliche as it may seem, but the quotation, â€Å"Time is Gold† is an understatement.For Americans, time is more than precious – it is almost â€Å"invaluable† in the sense that you can't add-on value to time. They have this attitude of maximizing the day so as to make themselves a productive person in as many hours as possible. In that case, it is normal to see most Americans, even students my age, working in a cafeteria, gasoline stations, and the like so that, while learning, they are as well earning. Being time-oriented, wasting time is a â€Å"no no! † In a signboard hanging along a commercial avenue I passed through reads, â€Å"Being early means being on-time.Being on-time means coming late. And coming late means being dead! † As we value time for being productive, so as to relax and pamper ourselves. Most Americans, especially those with better jobs, spend their year working as hard as they can so that by the time of vacation, they have more money to spend and a lot more time to reward themselves with a luxurious and satisfying vacation. We don’t just work to earn, we work to have fun. An Asian friend once told me that it’s really difficult to understand an American – or to grasp the core of a true-to-the-blood American.I ask him why and told me that the country is too diverse and totally mixed-up. American culture is too complex that it seems like its entire culture is a result of the mixing of this and that foreign culture, he added. Again, it made me wonder – are we really that hard to understand, or don’t we really have a â€Å"trademark† that would particularly identify us? This paper prove them wrong. And I've proven them wrong. Americans have their own identity, and treasure a set of values they call their own. What I've discussed in this paper are but some of our core valu es, which in my opinion, are the most vital of all.I may have not fully exercised some of these values now but I intend to when the right time and avenue comes. Entertainment media has successfully portrait the life of a true American through the many local and international films. However, what foreign viewers grasp is our more obvious character, that is, being liberated in words, actions and decisions. We practice and enjoy liberty that it almost overflow or over portrayed in movies. Liberated is equated to Americans. But we are more than just being liberated.We are more than a bunch of people who have our own free-will. We are not simply those Whitemen who exhibited liberty for the sole reason of being free. We are more than what they thought of us. In one word, we are â€Å"deeper. † Still in doubt? Just read this paper again and you'll surely understand what I mean.

Why Chniatown Should Be Conserved

Introduction As part of the Singapore heritage society, I believe that Chinatown should be conserved and should not be replaced by yet another integrated resort. Our Society is dedicated to the preservation and promotion of Singapore history, heritage and identity. We have held many projects to raise awareness of Singapore history and cultural heritage. Chinatown has and will always be a place with much historical value and a part of Singapore limited heritage. According to the dictionary, heritage indicates the characteristics, properties or quality that one inherits at birth.It is also he nation's mark of history, such as stately buildings, countryside, cultural traditions, that are seen as the nation's wealth to be inherited by future generations. Chinatown has been a part of Singapore and a part of our home since the early days when the early immigrants came to Singapore, being one of the few heritages that we are still able to keep hold of. Despite being rather small in size, th is little plot of land is the exact land that our forefathers stood on as they contributed to make Singapore what it is today.But with Singapore fast growth rate and overwhelming need to develop rather, it is not surprising that its historical heritage is being considered to be demolished to make way for the new. Conservation We wish to conserve Chinatown, as it allows us to be connected to our past. Our heritage reminds us of where we started from and of how we managed to progress from being a small fishing village to the bustling city that we are now, giving us a sense of direction in where we are heading to as a nation.Preserving our cultural heritage also goes a long way in explaining our rich cultural, political, social and educational values to the future generations. It is a lesson and an experience in which our forefathers handed down to us so that we can learn from their mistakes and successes, in hope that our nation will continue to grow into a better society. Our heritag e is very valuable and can even be considered as a form of â€Å"national wealth† that has been passed down to us.After receiving this honor and responsibility, we as the children of this nation, should play our part Just as our forefathers did and continue to pass this precious historical gem down for future generations to personally experience and remember our history. National Identity This year, Singapore has Just gained 48 years of independence, and we have successfully created an identity for ourselves that makes us as Gingersnaps more proud of our country and its accomplishments.A national identity is important to its country as it affects Singapore psychological defense, this would determine if Gingersnaps will stay to fight or abandon Singapore when faced with obstacles. The term ‘National identity is a person's sense of belonging to one's state or nation, a feeling one shares with a group of people, regardless of one's citizenship status. An identity is not an inborn trait but is slowly built up as a direct result of the presence of the similarities in people's daily lives, such as national symbols, language, the nation's history, culture and many others.For Singapore, one of these aspects is the Singapore multi-religious backgrounds, Singapore started off with majority of the population being immigrants from countries such as Europe, China, Arabia, India, Amelia and Penman, who came to Singapore in the early sass. While they came to Singapore in hope of finding a better future, they shared their religion to the rest of he country too. Although Chinatown started off as a Chinese settlement, but it contributes significantly to Singapore multi-religious identity as it houses many different religious buildings temples, churches and mosques.An example is the oldest Hindu temple in Singapore, the Sir Marianne which was built in 1827. During colonial times, it served as a refuge for new immigrants and acted as the Registry of Marriages for Hin dus. Today, in addition to its religious services and functions, the temple promotes various social, cultural and educational activities. Festivals such as Thematic (Fire walking ceremony) and Navigator are also celebrated there every year. The Thematic is an important ceremony to the Hindu culture, as it celebrates the honor of Draping who walked through a bed of fire and came out as fresh as a flower, proving her purity.Demolishing these religious buildings for the sake of the Integrated Resort will not only disrupt religious services, but it will also cause Singapore to lose part of its identity and history. Thus we believe that Chinatown should be conserved as it helps to build a unique Identity for Singapore. Festive Seasons During the Chinese New Year period, Chinatown is also the place that Gingersnaps first head to look for their Chinese New Year goodies and clothes.This has become a habit and tradition that most Gingersnaps abide by. At the same time, they are able to enjoy the Chinese New Year atmosphere as the place Chinatown during Chinese New Year, would be decorated with many stunning street lights. This bustling with people time of the year is when Chinatown finally regains its former glory, to the time when Chinatown was bustling with life, with hawkers selling all manners of things long the streets and people squeezing through the crowd to get their hands on the cheapest goods.It is also during times like these when families get together, no matter old or young to purchase items such as new traditional costumes, shoes, decorations, goodies in preparation for Chinese New Year. Chinatown then becomes a place that is unique and original as it allows the people to spend time together without the need to spend much money or for any technology, allowing them to bond. Memories Chinatown is a place where memories and shared experiences are being made.Even ill today, there are still people who have been living there since they were young and have built many memories about their childhood days there. Upon asked if she had any special memories in Chinatown, one of our interviewees, the owner of a textile shop, replied that â€Å"When I was young I used to spend most of my time in the shop. As my parent's watched the shop, me and my brother would study there. At times, we would also meet up with the other little kids there to play and run about the playground nearby. When asked why she chose to open a shop in Chinatown, she been with us for 3 generations. This shop meaner a lot to our family, as though it is our very own child. It also stores a lot of our memories as a kid. † Chinatown is also known as the ‘elderly district' and most of the people who stay there are actually elderly who have been living there since young. To them, Chinatown is the place where they feel at home, where they all their memories were made. These friends that they make slowly become more like their families than mere neighbors; taking care of each other and entertaining one another.Among the 25 people we interviewed, 85% of them agree that Chinatown should be conserved as it possesses lot of historical value and that from the many years living there, they have created many enjoyable memories there and do not want to ever lose them. However, if a third integrated resort were to be built here, all these experiences and precious memories would be lost and forgotten as generations pass as though they too have faded away from existence. Skills and Passion Chinatown is a place where people can showcase their skills and passion.In Chinatown, there are many little stores that sell traditionally hand-made local delicacies and clothing that are now hard to find in Singapore society. There are many tailors sewing Chicagoans, a traditional Chinese costume that are worn by Chinese females since the early days. These clothes are very significant to Singapore past as it is also one of the few artifacts the has been passed down from th e past to the current present. These Chinese costumes also remind us of how Singapore was in the past, and through the colors and decorations, we are able to bring out the colorful culture and heritage of our country's past.Also, there are many hawkers making their own buns through the traditional methods. Not only goes this allow the people to showcase their skills, this also allows them to survive in the Singapore context despite the tough competitions with famous chain-shops. This is at the same time beneficial to Singapore as it helps Singapore to increase their Job employment rates and allows the people to have the chance to chase after their passions in life despite their financial statuses.However, if the integrated Resort were to be built on Chinatown, this would cause many people to become Jobless and thus unable to support their families. Similarly, their passions can only be buried along with the rest of Chinatown. Tourists According to a research, destinations excelling in their cultural heritage are more likely to be on traveler's consideration list. Among the many respondents from 20 different countries, 57% of them agree that history and culture are strong influences on their choice of holiday destination, with only 15% of the people disagreeing to this statement.Conforming to this, Chinatown has been rated as one of the top ten attractions in Singapore due to its strong historical value and its colorful vibe. Due to our struggle towards progress after gaining independence on August 9 1965, we eve already demolished many of our memorable infrastructures in order to make way for the new, furthermore, only having 48 years of independence, Singapore does not have many places with much historical value.Hence, if we demolish Chinatown, we might be at a risk of having a sharp decrease in tourist rates, which may also not be as appealing to the tourists as compared to the uniqueness of Chinatown. From the opinions of most of the people we interviewed, most of them also agree that another integrated resort would only be redundant as we already have two other integrated resorts, them being Marina Bay Sands and Resort World Santos. Meanwhile, Chinatown is unique as there can only be one of it throughout the whole of this lifetime.If we demolish it, we would be losing it forever and we would never be able to build it and its priceless history again. A trip to Chinatown will also be more fruitful for the tourists. According to the theory of knowledge, the two main ways to gain knowledge is through experience and reasoning. Chinatown many historical infrastructure, vibrant atmosphere and heritage centre, allows them to reasonably experience the background and heritage of Singapore. Through this experience, it allows us to gain something more valuable than money, the power of knowledge and understanding upon visiting it.However, the Integrated Resort would only promote entertainment, such as gambling and shopping. Thus, by conserving Ch inatown , not only are we able to increase Singapore tourism rates and boost our economy, it also allows the tourists to benefit greatly from the experience and learn more about our culture and heritage. Land Scarcity Building an Integrated Resort over Chinatown would not only cause a lack of housing or the people who are currently living in Chinatown, but also with Singapore plan to increase the population from about 5. 8 million to 6. Million by 2030, this unbalance between the land use for entertainment purposes and the land used for housing purposes would create a serious problem for the people, such as overcrowding due to the lack of space. With over 5 million people currently living within the 710 km area of land, Singapore has been ranked the second most densely populated country in 2012. Singapore is already facing a problem with the lack of land and building more housing areas would not be an easy take. In addition, if an Integrated Resort were to be built in Chinatown, the residential areas in Chinatown would be lost, which would be a disadvantage to Singapore.Land scarcity is a dire situation and it may lead to unhygienic living spaces, which would make it easier for pests such as mosquitoes to breed. As Singapore is a tropical country, we are very prone to dengue's. From the 16-22 June 2013, there was a total of 82 dengue outbreaks within that single week, and from the start of January to 13/08/2013, there has already been 6 unfortunate victims who have passed away due to dengue fever. From this, we can tell the severity of Dengue Fever in Singapore, and with the unhygienic environment, this would lead to a higher risk of the people having Dengue Fever.Hence, not only will Chinatown help in the heritage of Singapore, but it will also help in the land constraint problem Singapore is facing currently. Conclusion In conclusion, I strongly feel that we should conserve Chinatown as it is part of our home town and heritage. It reminds Gingersnaps of how far Singapore has progressed from being Just a free port all the way to being the central trading port of people who lived, worked and visited Chinatown in the chophouses, temples and mosques. Chinatown is a place that holds the memory and identity of Singapore.

Keeping google googley - Case Study Example From this research, it is clear that bureaucratic organizational culture is one of the biggest growing concerns of Google Inc. The bureaucratic organizational culture served noninstrumental in managing around 17000 employees. The company should have adopted the Hofstede Cultural Dimension which constitutes of four cultural dimensions like PDI (Power Distance Index), UAI (Uncertainty Avoidance), IDV (Individual Collectivism) and MAS. Power Distance Index indicates the degree to which power is distributed unequally among the members of the organization. It also indicates how the less powerful members of the organization accept the prevailing inequality readily. Individual Collectivism is the degree to which the members are integrated into various groups. Masculinity Feminity Dimension refers to the distribution of the values and roles between the genders. In countries with a high masculine culture, the difference between the gender roles are prominent and vice versa. The tolerance and acceptance of the societal norms are evaluated and measured for uncertainty and ambiguity purposes. The cultural dimension of various countries is evaluated and calculated based on certain scores, which help in determining the various cultural elements of a country and the organizational culture of a particular country. It is observed from the case study that the organizational structure is not well defined and is loosely oriented.... Support culture helps in promoting shared assumptions, values, socialization and norms, etc. This helps in improving the organizational commitment among the organizational members (Meijen â€Å"The Influence of Organizational Culture on Organizational Commitment at a Selected Local Municipality†). Transformational Leadership It is observed from the case study that a well defined hierarchical structure is absent in the company which has led to chaotic and rapid decision making within the organization. Participative decision making is applicable only in certain circumstances; otherwise it will lead to confusion and chaos. Thus, the managers should adopt a leadership approach at several levels which would help in managing situational crisis and help in organizational effectiveness. Transformational leadership approach is mixture of charismatic and bureaucratic leadership approach, which helps the managers to raise the motivational level and morale of the employees. Transformation al leadership approach paves the path for organizational success and improves the productivity and efficiency of the employees. Although, rapid decision making is pervasive in the company it should be noted that some important decisions require cautious and planned thinking. Transformational leadership helps in improving the organizational effectiveness by constantly monitoring the organizational procedure and providing significant strategic inputs (Hautala 777-794). External Analysis of Recommendation Among the above three recommendations it would be advisable if the management follows the transformational leadership approach, which would help in effective managerial decision making and improvisation of the existing

Recycling in Australia and China Essay Example | Topics and Well Written Essays - 1000 words

Recycling in Australia and China - Essay Example In fact, many Chinese people are relying on garbage and unwanted materials in order to make both ends meet everyday (Jazeera, 2010). The ultimate goal of China is to create a big industry for its recycling industry, but Australia is more into regulating the balance flow of its materials economy. One important distinction between Australia’s recycling industry and China’s can be depicted in their major objectives towards their recycling programme. Both of these countries seek to optimise the full advantage of the proper handling of waste materials that in return will help sustain their economy. As a result, common to their strategy when it comes to their varying recycling programme is their goal to achieve economic sustainability. In Australia for instance, the Australian Council of Recycling (ACOR) seeks to achieve efficient, sustainable materials economy. Part of this organisation’s function is to help the government addressed society’s internal issues to wards the handling of their waste materials. In China, there is a remarkable recycling market. ... y Unlike Australia, China is still in its infancy stage when it comes to organising its entire recycling industry that is why it needs to come up with relevant incentives and motivating forces to influence the stakeholders (Mo et al., 2009). Australia is highly organised when it comes to its implementation process on its recycling programme. This is due to various collaborations of its stakeholders which eventually have resulted to positive support and impact on its entire recycling industry. Remarkably, unlike China, Australia has become so focus with sufficient time to concentrate on specific objectives. For instance, to ensure maximisation of recovery and re-use, copper and zinc recycling in Australia are targeted to reach in their discard flow by about â€Å"105% and 155% to 150 Gg Cu/year and 145 Gg Zn/year† (Beers and Graeded, 2007). Furthermore, upstream and downstream sorting of residues is an integral part of Australia’s policy instrument for recycling. Part of this is to manage wood waste which has â€Å"taken a large amount of landfill space† and is said to contribute to â€Å"global warming as the process of decomposition takes place resulting to the emission of carbon dioxide and methane gases† (Taylor et al., 2009). These clearly indicate that Australia has clear and specific goals in its overall plan for its recycling strategy. In addition, there were â€Å"Industry-led initiatives collaborating with national government: Australia’s National Packaging Covenant ensures market for new materials recovered from recycling; Aluminum can industry helps encourage the community for recycling by paying people for using aluminum cans delivered to the centre; drumMuster helps to initiate collection of empty, cleaned and non-returnable crop protection and animal health

Assessment and Evaluation in Higher Education Local plagiarisms Essay

Assessment and Evaluation in Higher Education Local plagiarisms - Essay Example Therefore many institutions have laid out guidelines and rules concerning these vices, and even stipulated the penalties for anyone who does not comply. The issue of intertextuality is addressed, which involves the author borrowing and transforming a text or a reader referencing one text in reading another one. Transgressive intertextuality involves the breaching of acceptable borrowing practices. The interpretation of the concept of improper intertextuality varies from one lecturer to another, according to interviews conducted on lecturers from various disciplines. The reasons for this disparity include the unique expectations and practices of each discipline. The results of these interviews showed certain areas where students experienced problems in citing sources. These include poor paraphrasing, students’ identities as the authors, improper understanding of common knowledge, information contained in many sources such that it is difficult to pinpoint its source, and the uni que expectations and practices of each discipline. Therefore it is suggested that there should be a different definition of inappropriate intertextuality for each discipline in order to address various disciplinary perspectives. This paper seeks to evaluate how the problem of plagiarism and collusion is viewed and attempts to curb it in various academic institutions. The paper mainly focuses on the lecturer’s views about transgressive intertextuality in various disciplines like the humanities, history, languages, engineering, law and fashion. The paper has successfully tackled a number of issues. The lecturers’ responses mostly comprised of their own personal interpretations of intertextuality and the experiences that they had encountered while dealing with their students, therefore they were able to give a picture of the real situation that was taking place in the institutions. The paper also highlights the opinions about transgressive intertextuality in various disci plines; therefore the students can get to know what is expected of them in writing academic papers in their respective disciplines (Worton and Still 1991). Suggestions are also given on how to deal with transgressive intertextuality. The lecturers who were interviewed gave details about how they had punished the culprits and other steps that they had taken to reduce the misconduct. The study also highlights the future repercussions of indulging in plagiarism and collusion. Some of the interviewees expressed the feelings of anger and sympathy for those students who were practicing plagiarism because they felt that they were jeopardizing their careers. Cases of plagiarism can also lead to termination of grants. According to Maier (2011), plagiarism tarnishes the professional reputation of an individual and may make it hard to secure a job in the future because the prospective employers may view you as dishonest and lazy, and therefore not fit to work for them. The study also clarifies that it is not possible to treat the issue of transgressive intertextuality in the same manner across all disciplines because different disciplines have varying demands. For instance, a history student is expected to come up with an account from an existing text while a literature student tries to interpret and react to written works. Therefore any copying in literature is not tolerated while historians do not deal with it severely because they understand that students will always use other peoples work in writing

The Rules of the Game (1939) Essay Example | Topics and Well Written Essays - 750 words

The Rules of the Game (1939) - Essay Example Its real prints were vanished during the strikes of World War II but it later (until the 1950’s) was redesigned almost completely by French film makers Jean Gaborit and Jacques Durand in cooperation with Jean Renoir. Today the film has been applauded and considered as one of the best films ever created in cinematic history. The main cast of the film comprised of Nora Gregor, Paulette Dubost and Marcel Dalio. Long Take and Deep Space Composition Long Take A long take is an unaltered or uninterrupted shot in a film that lasts much longer than usual shots in the same film or in general relative to others. It is carried out so as to enhance dramatic feel and narrative effect in the film. It is created normally using a special camera that could remain steady instead of shocks and imbalances, a Steadicam. Deep Space A film uses the element of deep space when noteworthy characters of an image are placed both near to and far away from the camera. Here, there is no need to focus on the elements in the image as what is the significance of deep focus. Often, directors want to show the real distance between two objects in a scene to the audience and that images near and distant to the camera are both important. The way of staging in a deep space composition is almost the opposite of shallow space. Jean Renoir is one of the directors who use deep space and deep focus in their films as their signature element. From the Film There are a number of sequences or scenes in the film with a long take and deep space composition. A sequence that can be discussed here is of the stage drama which is performed in a horror genre to entertain the audience. It is a fascinating stage show with interaction with the audience and a piano score as well in the background. This sequence is a single shot with no editing and cuts and a heavy effortful camera work has been done to depict the drama and narration in it. The scene lasts for at least 1 minute 50 seconds without any halts. This se quence pertains to a climax in the film which is a famous house party sequence in which there is a stage performance by amateurs to entertain guests and neighbors. This sequence has been applauded as one of the best moves to show the work of long take and deep space compositions together with no cuts. Characters present are all guests and neighbors with non-professional but enthusiastic actors on the stage entertaining and interacting with the audience. The camera work carried out by Renoir in this sequence is phenomenal. The camera is moving forward and background for more than six or seven times; moving from audience to the stage and then to the backstage, forward into the house to the rooms and corridors and almost everywhere in the house. This camera work is quite appreciable effortless. Each and every character is visible whether near or distant to the camera which shows that a long take and a deep space both have been utilized efficiently. While watching this sequence, a user can see all the movements of characters and the clear picture of the background animations going on; this is an imperative attribute of a deep space composition that every character is visible and not blurred. The light work which seems like lanterns being floated in the air by those performers on the stage is quite nice of a work (Ebert R. 2004). Purpose of such sequences The purpose of long take or deep space compos

American Legal Regimes and Wealth Creation Term Paper - 1

American Legal Regimes and Wealth Creation - Term Paper Example Most historians described this as the conflict between labor and capital. The conflict that was filled with a lot of damage of properties escalated well into the 20th century and ended when the war started. By early 1900, the country was already filled up (Cohen 234). Major cities all over the state were packed with hundreds of thousands of poor American laborers who worked in deplorable conditions. Corruption during this period is considered the most escalating issues that brought all the problems that the country was facing. The progressive movement is considered to have been the solution to the problem that seemed to be driving the country way ward. It is hard to say that the movement fixed everything, however, remarkably little passed unchecked. The movement grew outside the government since none of the politicians was willing to support the economic and social change that the progressive movement brought. However, after pressure was applied b\y the movement the government finally decided to stand alongside the movement as it fought corruption out of the system. Most historians accredit the year 1896 as the period during which the progressive era began (Hayek 12). It is also viewed that most reforms that the movement had advocated for begun just before the country join t the war in 1917. However, even with is mind it is considered that most of the reforms begun way back during the colonial period although none of them had picked up until the modern era this being the 1900s. One cannot claim that all citizens and domestic workers have a fair playing field even now. It is also had to claim that the countries politics are free from corruption. Thus, it is considered that the movement that begun back in the late eighties lives on pushing for reforms and a corruption free political system (Cohen 234. During this era, which is most commonly

A Casualty Clearing Station Essay Example | Topics and Well Written Essays - 1000 words

A Casualty Clearing Station - Essay Example Dr. Hayward started by explaining how the conditions at war were not as one expected them to be but they were rather tougher and difficult to cope up with. To support this stand, he began his narrative by stating that he had worked for twenty years as a surgeon in the general hospitals in an area and he also had an exposure to war like situations as he had served as a surgeon at British Red Cross Hospital, Netley during the initial period of the War. But the author explains in his narrative that this familiarity with war like situations was in no way close to the experiences that he gained at the Casualty Clearing Station (C.C.S) at Crouay where he got posted upon his request in July 1918. This was because the C.C.S received patients directly from the war field and this was different from his working at the British Red Cross Hospital. Thus, Dr. Hayward provided an inside picture of the C.C.S by beginning his compilation from his normal days of work and ending it after his work at the C.C.S. The firsthand account of Dr. John A. Hayward is a text that provides historians with not only geographical evidence but also with historical and cultural evidence. From the geographical perspective, his writing narrates the war experiences of the different regions in France beginning with the Base Hospital at Trouville where he only dealt with minor injuries. This was followed by his work at the C.C.S at Crouay where he treated patients who were pouring in from the battlefield.  

Equality and Diversity Essay Example for Free

Equality and Diversity Essay In this assignment I will demonstrate my understanding of equality and diversity as a key approach to policy and practice within my setting. I will make reference to current legislation such as equal pay act, disability discrimination act, sex discrimination act and equality act. Other areas of discriminatory practice I will discuss are language and terminology, stereotyping and attitudes in relation to children and young people. I will explore anti discriminatory practice and diversity that is within the everyday role of the early years practitioners. I will also explore an area of my practice using my understanding of equality and diversity through an audit of provision to develop practice and outline any issues. The audit I will carry out will specifically be aimed to support children with additional needs within my setting. I will look into staffing, the environment and the funding available. Following completion of the audit I will write a report identifying any concerns and making recommendations to enhance the experiences that children with additional needs will gain from the setting. I am going to demonstrate my understanding of equality and diversity and how it affects the policy and practice in my setting. I will make reference to current legislation to support my discussion. Legislation I will refer to includes: Equality Act 2010, Human Rights Act (1998), Employment Equality Act Regulations (2003), SEN and disability Act (2001/2), Race Relations Act (1976), Sex discrimination Act (1975) and the Warnock report (2005). I will discuss areas of discrimination in early years practice like, language and terminology, prejudice and stereotypical images and attitudes in relation to children and young people. I will also explore anti discriminatory practice and the diversity in early years settings. The legislation I am going to discuss has been incorporated into my setting by using the essential information in the policies and procedures. The policies and procedures are given to all employees upon recruitment so all staff are aware of the laws and regulations they have to work to. Richardson, R (2011) it is the requirement of the public sector equality duty that equalities is a due regard for schools. Schools are required to eliminate discrimination, advance equality of opportunity and encourage good  relations. The equality act is used in the equality and diversity policy in my setting. OFSTED also look for equality in the setting looking for the progress of spiritual, moral, social and cultural development in the development of the children attending the setting. It is also important that the setting do not discriminate against the nine protected characteristics that are outlined in the equality act 2010. It is important for all children accessing the setting to have access to the curriculum which is the Early Years Foundation Stage (EYFS). As a setting we ensured that all the children wishes, preferences and beliefs are taken into account as children learn more effectively when they feel safe and secure. The setting intervenes and provides additional support to those children who are not developing and progressing. The planning process also includes the support needed for any children with additional needs. Garside, R (2011). The sex discrimination act 1975 works to eliminate the discrimination against men and women and promote the equal opportunities for both men and women. This act is evident with the children in the setting as they all have equal opportunities in their unit, the same access to toys, activities the outdoor areas. We do not stop girls from playing with cars and boys playing with dolls, they require equal opportunities to develop the knowledge and skills they require in life. The SEN and disability act 2001/2 is an amendment of the education act 1996. The act is there to prevent discrimination against children with SEN or a disability in school and ensures them an education in mainstream school unless the parents request otherwise or it is incompatible with the education of the other children. This is seen in my setting as we are a nursery that accepts children with additional needs unless we feel that we cannot meet those children’s needs without unrealistic changes to the setting. The setting currently has children with Autism, global learning delay, speech and language disorders and chromosome 16 disorder as well as other children with undiagnosed additional needs. The Warnock report 2005 focuses on the future of education and inclusion into mainstream schools. The Warnock report changed the way that we see children with disabilities and encouraged inclusive education, however now inclusive education is favoured the SEN school system is become devalued despite the work they do for the children they care for. My setting is a inclusive setting for children with additional needs and we support the development of the  children and the preferences of the children. Within the early years education system discrimination can occur, it is an aim of my setting to prevent and reduce discrimination, they do this using the policies and procedures and regularly sending staff on training courses to gain knowledge of current legislation and procedures. Prejudice and stereotyping are often seen in education settings because of the high number of different ethnic and cultural backgrounds and the lack of understanding and knowledge that children and young people have. Stereotypes tend to originate from the media of what is seen as ‘cool’, the media also labels certain groups as not being as important as others and can cause children with disabilities isolating themselves from the rest of the group. Judgments can also cause discrimination as people can make poor judgements of people and discriminate against their good qualities just because they are in a wheelchair or have ADHD doesn’t mean they can’t play the same games as the other children they just may need more support than the others. In early years setting we use policies and procedures to outline the government legislation, we do not simply publish the legislation because of the way they are presented and the terminology they are written in. The policies and procedures are designed around the legislation in a way that are easily understandable for the staff and parents/carers using the setting. We make sure that the policies and procedures are accessible for all parents/ carers and staff. It is no longer acceptable to base an education programme on the stereotype of emotional behaviour being feminine, artistic and marginalised and rationale behaviour as masculine, logical and mainstream (Yelland, N 1998). It is important to give all children equal opportunities and allow boys and girls access to all resources and activities whether that be the girls playing with the cars and the boys playing with the dolls or both genders playing outside on the slides and bikes, this is all available in the work setting. Stereotyping can be offensive and cause biased thinking and actions, the tasks set in education programmes could favour groups depending on their culture and previous education (Frederickson, N and Cline, T 2009). As early years settings are examples of anti discriminatory practice and diversity through the early years foundation stage practitioners can provide a programme for the children that meets all their needs, wishes and preferences in learning and development. Stereotypes leading to discrimination through the exchanging of humorous stories can reinforce negative perceptions and group boundaries, this discrimination may be seen between the staff which will give them negative attitudes towards groups of children and parents. In my setting the staff work closely with the early years foundation stage and attend training courses which prevent this from happening. Often no cure is possible for disabilities. However, medically, disabilities were diagnosed, managed and treated. This was challenged by the children’s parents who said they were seen as medical cases rather than individual children. The social model focuses on the children as an individual and highlights social difficulties they may have as a result of their specific disability. The social model respects the needs, wishes and preferences of the individual child when it comes to medication and treatment. In early years there needs to be a good balance of the two models for children with SEN. Without the medical model we would have no knowledge of any causes of management systems that could be used with the children to help them develop and without the social model we would not be meeting the children’s individual needs. Through this essay I have demonstrated my understanding of equality and diversity and how it affects the policy and practice in my setting. I have made reference to current legislation to support my discussion. Legislation I have referred to includes Equality act (2010), Human rights act, Employment equality act, SEN and disability act, Race relations act, Sex discrimination act and the Warnock report. I have discussed areas of discrimination in the early years practice like language and terminology, stereotyping and anti discriminatory practice and the diversity in early years settings. I completed the audit after a meeting in the setting where I was informed of the parent wanting to start in the setting, a discussion was held about how we were unaware of the disorder and didn’t know anything about it. I chose to do the audit here because it was a great opportunity to highlight areas we needed to change or adapt to meet the needs of the child and his family. It was important for us to make the setting accessible for this child because Pugh, G (2010) says it was the focus of the children act (2006) for integration of all services for children with special educational needs (SEN), which supports the aim the best start for children. After the parent was shown around the setting and she told us she wanted her child to attend, a discussion was held between mum, the manager and the SENCO. It came from the discussion that mum wanted the child to start in the preschool unit as he would soon be 3, although his developmental age was much younger. As we did not want to go against mum’s wishes and preferences we made substantial changes to the preschool unit, with the support of the EYP and external agencies we made the preschool unit a suitable environment for the child. Mum was very nervous about leaving her child so the SENCO who was to be the child’s key person started home visits to see the child and talk the mother about his needs. The child then started a long transition into the setting lasting a month and a half. The changes made to the preschool unit incorporated the needs of the child well and after several weeks attending the setting he is getting on well, the SENCO is assessing him constantly t o make sure that he his developing and progressing well and has just took on board teaching herself makaton to communicate more effectively with the child. From doing this audit I have found that the staff in the setting work well to the standards set out in the policies and procedures. The extended transition period used with the child also helped the parent to come to terms with leaving her child with somebody else, this could be something  that could be incorporated throughout the setting and we could make the transition period more flexible for all children coming into the setting. I have also found that the setting not only works together as a team but with work with others like parents and external agencies to create a partnership to help the child. A set back that we came across was researching the disorder, as it is so rare and varies considerably between each sufferer it was hard to find much information, we had to go on the information that mum gave us to create a suitable environment and provide for the child to help him develop and progress, I would recommend regular assessments to identify the gaps in his development so t hat the setting can provide for these and he can progress ready for school. In this assignment I have demonstrated my understanding of equality and diversity as a key approach to policy and practice in my setting. I have made reference to current legislation that has been used to compose policies and procedures in my setting. I have discussed areas of discriminatory practice that relate to children and young people and I have explored the anti discriminatory practice and diversity within the everyday role of practitioners working in early years settings. I have explored an area of my practice using an audit of provision and my understanding of equality and diversity. This was done to develop practice in my setting for children with additional needs. I observed and evaluated the staffing, environment and available funding. Through a report I made recommendations of how the setting can develop practice to support the children attending with additional needs.

Photo Aging of Skin

Photo Aging of Skin Photo aging is the effect of chronic ultraviolet exposure on the skin, and the term was first used by Kligman, back in 1986(1). Incidence of Photo aging is increasing in year by year. Photo aging is premature aging of skin, which is a very complex process which causes progressive functional and aesthetic changes in the skin. Photo aging is mainly due to Ultraviolet (UV) radiation that is UVa and UVb radiation and can also be due to genetic factors. Apart from UVa and UVb other rays like infrared and visible rays are also responsible for Photo aging (2). Photo aging is entirely different from chronological aging. Chronological aging, which is a natural phenomenon and cannot t be reversed or prevented like Photo aging and they differ clinically and histologically from Photo aging. Photo aging is characterized by wrinkling of skin, loss of skin tone, loss of resilience due to loss of skin strength and skin elasticity. Photo aging appears mostly in areas which are exposed to sunlight like face, neck and back of the hands and is clinical presentation is with deep coarse wrinkles mostly around the eyes, then the mouth and on the forehead, next feature is uneven skin color and dryness, various spots which are pigmented like age spot, liver spots that are mottled pigmentations and freckles can also be seen, skin tone will be lost and will be leathery, spider vein can be seen on the nose, cheek and neck (4). The mechanism behind Photo aging relating to UV rays is by producing an in balance between TGF ÃŽ ²2 and AP1 damage, TGF ÃŽ ²2 is an activator protein, which promotes collagen production and AP1 is a transcription factor which inhibits collagen production by increasing production of Metalloproteinase which break down collagen and there is another enzyme TIMP which inhibit MMP. In normal skin TIMP and MMP are in balance (5) (6). Whenever we are over exposed to UV rays there is an increased activity of AP1, which in turn increases MMP causes an imbalance between MMP and TIMP. Apart from increase increased activity of AP1 there is also decreased expression of TGF ÃŽ ²2. This imbalance leads increased proteolytic activity leading to damage to collagen which will be corrected if not further exposed to UV rays, but if the skin is further exposed to UV rays damage to collagen will remain as such and skin will be formed abnormal in the form of wrinkles (6).decreased expression of TGF ÃŽ ²2 c auses decreases production of collagen . This damaged collagen and lack of new normal collagen formation altogether will lead to decrease in quantity of collagen forming leathery skin (fig.) MMPs is induced by UV rays that induces by both UVa and UVb. UVa and UVb act by different mechanisms. UVa act by indirectly activating ROS, which intern produces other effects like lipid peroxidation, transcription factor activation, formation of DNA strand breaks, unlike UVa, UVb induce MMP by directly producing DNA damage and by ROS(7). Whether it’s UVa or UVb, ROS generation is the important factor in Photo aging. SUN AP1 ROS Generation TGF ÃŽ ²2 MMP procollagen production Collagen break down Imperfect repair Invisible solar scar Repeated UV injury Visible solar scar (Wrinkling of photo aging Mitochondrial cells main function is to produce energy for the cell ,which is generated by a process called oxidative phosphorylation ,which is commonly known as electron transport chain .this oxidative phosphorylation usually have some error ,resulting in production of ROS which produces oxidative reaction. When human skin is exposed to uv rays ,it produces ROS .this ROS will cause damage to mitochondrial DNA which in turn leads to reduce of capacity for oxidative phosphorylation which accelerates production of ROS which again will cause mitochondrial DNA damage and the cycle is repeated resulting in conditions like photo aging (oxidative damage to mite dna) UVa ROS Mutations of mitochondrial DNA Acceleration Reduced OXPHOS capacity With the understanding of mechanism of photo aging, many strategies has been put forward for the prevention and treatment of photo aging .photo aging can either be prevented by using substances which the action of uv rays on skin or by giving treatment to reverse photoaging.it is well known that dark people develop less photo aging compared to white skin people which is thought to be due presence of increases melanin. So artificial tanning of skin by using thymine dinucleotide is a way to protect from photo aging (telomere mediated effects).another highly used way of protecting skin against uv rays is by using organic and inorganic uv filters as sunscreen creams however there is a controversy regarding effectiveness of this sunscreen formulations.( Coenzyme Q10, a cutaneous antioxidant and energizer. As per above explained mechanism of photo aging it’s clear that giving an antioxidant will have high amount of benefit and many studies are done with antioxidants. All these strategies are for prevention of photo aging. There are also studies with vitamin a, all Trans’ retinoic acid for repair of already existing damages to the skin. (. (New and emerging treatment for photo aging) It’s a known fact that Skin photo aging is caused by the solar rays induced oxidative stress. Apart from the mechanism of imbalanced mmp and action on mitochondrial DNA there are other mechanisms involved in skin photo aging .In a in vivo study it was shown that when skin get exposed to ultraviolet rays cholesterol undergo O2 oxygenation reaction with the help of free radicals and or O2 to form a peroxidation product cholesterol 5 ÃŽ ±hydro peroxide which form cholesterol aldehyde .cholesterol aldehyde modify proteins to form various pathological conditions including photo aging(formation of cholesterol).in another study it was reported that apart from cholesterol another target of 02 oxygenation reaction is unsaturated fatty acids like oleic acid and linoleic acid (age related ).this animal studies proved that 02 produced from type ii photosensitized reaction is involved in the injury of skin exposed to chronic UVa by oxidative stress. From above its clear that free radical and or O2 is involved in the process of photo aging, so using an O2 quenching substance like carotenoids will help in prevention of photo aging (singlet oxygen quenching). The normal skin itself has antioxidant protective effects .this antioxidant protective effect are produced by endogenous enzymatic antioxidants like GSH peroxidase ,SOD and catalase as well as non-enzymatic antioxidants like vitamin E ,vitamin C ,GSH, Uric acid and ubiquinol.when most there is an attack of ROS ,the skin will itself form an antioxidant defense complex the most important one among them is manganese superoxide dismutase (mnSOD) which a mitochondrial enzyme (antioxidant defense mechanism.)whereas when the skin is exposed to uvrays repeatedly this endogenous enzymes has less as evidenced by the less concentration of antioxidant enzyme in photo aged skin ,especially in the epidermis and stratum cornuem. Which makes it mandatory to use an external source of antioxidant when skin is exposed repeatedly to UV rays. (pandet et al) On over all its known that main pathology involved in process of photo aging is oxidative reactions .with the understanding of that many studies have been done with different exogenous antioxidants since 30 years .different has been tried by different researchers .elmore et al studied with topical vitamin C cream .which has shown improvement.boelsma et al in 2001 reported vitamin E compliment the photo protective effect. Ribaya-Mercadoet al.in a study established that lycopene protect against UV induced photo aging in humans. Stahl and Krutmann, 2006 reported in a study that carotenoids gives basal protection against UV induced photo aging. Effect of carotenoids particularly beta carotene was studied by cho et al in 2010 and proved that dietary beta carotene has effect on photo aging. There are several studies done on photo aging with topical tretinoin and most of them has shown positive results one among them is study done by voorches in 1990 where he proved that topical tretinoin r educe the effects of photo aging. Hoppe et al studied with topical coenzyme q10 ,it has shown positive effect in preventing photoaging.richard et al done in vivo study with zinc treated fibroblast ,which showed a positive result in uvr resistance .in 2002 a study was done with resveratrol by afaq and mukhtar ,which showed effective prevention of induced increase in skin thickness .another antioxidant used in study was green tea ,green tea proved to reduce uv induced oxidative stress in a study done by katiyal et al.lu et al done a study with caffeine ,caffeine showed increase in p53 ,slowed cell cycling . Singh and Agarwal, 2002 reported that silymarin prevent photo carcinogenesis. Cocoa was proved to have photo protective effect against uv induced erythema in a study done by Heinrich et al., Ultraviolet rays UV rays are electromagnetic rays which are naturally emitted from the sun along with other electromagnetic lights like visible and infrared rays. Electromagnetic spectrum of UV rays extends between x-rays and visible lights that is 40 to 400 nm. UV rays are classified into three types depending on its wavelength as UVc (220-290 nm), UVb (290-320) and UVa (320-400 nm). UVa having longer wavelength and the least energy and UVc have short wavelength and high energy, having high energy means its most hazardous but fortunately it doesn’t cross ozone layer where as UVa and UVb cross ozone layer in small quantity. UVa is the one responsible for production of tanning with the help melanin pigments when exposed to the sun, which is actually a defense mechanism to protect human skin from further exposure to UV rays (2), it’s also used in vitamin D synthesis, having said so over exposure of UV rays may cause erythema , toughening of skin and inflammatory reaction to eyes and over exposure for a long term leads to cataract formation ,immunosuppression , Photo aging of skin and skin cancers(3). Artificial UVA lights are widely used in health science for phototherapy in case of certain skin conditions like psoriasis for sterilization and disinfection and tanning booths (4)(2) (5). Among skin cancers, non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma are more common, but rarely fatal. Melanoma and non-melanoma combined leads to 66,000 deaths per year. Another hazard of long term of UV ray exposure on the skin is premature skin aging, photo dermatomes and Actinic keratosis which are due to degenerative changes in cells of the skin, fibrous tissue and blood vessels (6). Mixed carotenoids Mixed carotenoids are a combination of different types of carotenoids, in a particular combination. Carotenoids are plant pigment which are having 40 carbon atoms in a molecule (1). Carotenoids are mainly of two type’s one containing carbon, hydrogen and oxygen containing and other with carbon and hydrogen, which are named xanthophylls and carotenes respectively (2). Carotenoids are plant pigments which are synthesized by plants in higher amount and partly by algae and bacteria(2). Carotenoid is abundant in animals also, which they acquire by eating plants. Carotenoids are of different types around 700 carotenoids have been identified, most commonly available (3). Carotenoids like lycopene, beta-Cryptoxanthin, beta carotene, lutein, zeaxanthin. Alpha carotene, echinenone. Capsanthin, astaxanthin, canthaxanthin and all are commonly available fruits and vegetables like tomato, mango, carrot, citrus lime, green leafy vegetables, mushrooms and all, some of the carotenoids are well absorbed and are present in plasma (4) (5) . Carotenoids were considered to be just as provitamin A, and importance of carotenoids in that case is itself considered to be the nontoxic reserve of vitamin- A (6)(4) .Recently its discovered that carotenoids are not just provitamin A it has other actions as well, from that point on immense research has been going on with carotenoids in almost all the system and all over the world (7). Carotenoid is normally present in tissue and blood of humans. Adipose tissue is the most abundant one in carotenoids followed by liver and muscle, apart from this tissue carotenoids are also present in other tissues like corpus lithium, adrenal gland, macula lutea (8). Among carotenoids lutein, Cryptoxanthin, lycopene, alpha carotene, beta carotene are the ones which are commonly available in serum and other tissues like adrenal gland (4)(3). Human skin contains carotenoids like ÃŽ ±-, ÃŽ ³-, ÃŽ ²-carotene, lycopene, lutein, and zeaxanthin (9) Carotenoids are proved to be useful in many diseases and its many research is in process also, one of the most important research work related to carotenoids is its useful in cancer, especially in skin cancer, it’s been found that carotenoids acts in case of cancer by several mechanisms, one is that it protect against nuclear damage and sister chromatid exchange and another is that it when fibroblast are exposed to x rays, UV rays or to any chemicals like Cholanthrene it undergo transformation leading to cancer, carotenoids inhibit this transformation (4). In UV induced skin tumor it proved that carotenoid helped in delaying skin tumors induced by UV rays, over all carotenoids seems to inhibit development of cancer in the initial stage itself (10) (4). Another field or research with carotenoids is in ageing related, immune system, fertility, ischemic heart disease, and diabetes mellitus. Carotenoids act by several mechanisms, but the entire mechanism of action is not yet proved in different part of the system, it has different action which is still on research, some of the mechanisms related to cancer has been discussed already. However, one of the well-known action of carotenoids is by an antioxidant mechanism, that is it act against oxidative stress(11). Oxidative stress is a result of reactive oxygen species (ROS) reaction or a free radical reaction (12). Reactive oxygen species are produced as an unfortunate byproduct of redox reaction which are a part of oxidative phosphorylation to produce ATP in mitochondria rays are produced by other redox reaction also, some of the examples of ROS are superoxide anions, hydrogen peroxide or hydroxyl radicals. This reactive oxygen species accumulation will lead to serious problems, which are inhibited by killing this race either by enzymatic mechanism or non-enzymatic mechanism. Enzymatic mechanism is by the help of enzymes a nd non-enzymatic approach is by the use of antioxidants like ascorbate and glutathione, tocopherol, flavonoids, alkaloids and carotenoids. So normally in human body oxidants are antioxidants are maintained in a balanced state, any break in that balance leads to trouble. But unfortunately the balance is disturbed in day to day life and so there is always a oxidative damage in the process (13) (14) (15). Oxidative stress leads to many problems. Harman in 1956 itself has proposed that ageing is related to oxidative stress. According to him, rose will produce some irreversible deleterious changes to molecules, which was later on approved by many other researchers of past and present, a more elaborate finding was done by Halliwell B. He observed that the rays produced in mitochondria primary target is mitochondrial DNA itself, which leads to further production of Ross and this cycle is repeated leading to ageing. This case is similar when it comes to ageing of skin too, when skin is exposed to UV irradiation and oxidative stress is produced leading to ageing and as explained by Biesalski et al that oxidative stress can be prevented by antioxidants like carotenoids (17) (18). Another of the mechanism involved in photo aging o2 oxygenation of unsaturated lipids in the skin and cholesterol in the skin. This peroxidized cholesterol accumulation partly leads to activation of MMP9 (formation of cholesterol. (Age related when we use carotenoids it inhibit o2 oxygenation of unsaturated lipids and it also inhibit o2 oxygenation of cholesterol which in turn partly suppresses MMP 9 action. (Peroxide cholesterol induced)+participation of singlet oxygen. . Advantage of taking carotenoids is that it accumulates in human skin which is commonly known as carotenoderma.carotenoids deposit more in palm of the hand and forehead. And the level of carotenoids present skin is proportional to the amount of carotenoids present in serum and its fortunate human absorb wide variety of carotenoids. (Carotenoderma a review).one of the reason for abundance of carotenoids in skin is that stratum cornea has a lipid layer which has more affinity to carotenoids. leading more amount of carotenoids in the stratum corneum . Carotenoids protect sperm from the rose by its antioxidant property there by maintaining fertility. Carotenoids also has action female fertility by helping the formation of corpus luteum and many other aspects of reproduction as well, though a specific action of it is not known. Carotenoids have other actions like reducing risk of age related macular degeneration(20), they also reduce risk of age related cataracts (21), carotenoids reduce risk of hypertension and ischemic heart disease by lowering Tri acyl glycerol and increasing HDL (22). Apart from this proved effects and mechanisms there are suggestions of many more of effects and mechanisms for carotenoids where immense researches are going on. An intervention study demonstrated that dietary carotene Protects the human skin from the UV light-induced erythema. (38) Stahl et al.(39) found that combination of a relatively low dose of total carotenoids (25 mg/day) and vitamin E (RRR-ÃŽ ±-tocopherol; 335 mg/day) significantly diminished the erythema on dorsal skin induced by illumination with UV light after 8 weeks. They also revealed that the intensity of erythema 24 h after the irradiation of UV light was diminished in a group receiving mixed carotenoids containing ÃŽ ²-carotene, lutein and lycopene (8 mg each/day) for 12 weeks.(40) In a separate study, intake of tomato paste rich in lycopene (40 g/day) was also shown to be effective in the prevention of erythema formation induced by UV light after 10 weeks.(41) These studies strongly suggest that dietary carotenoids accumulate preferentially in the skin and prevent it from UV-induced photooxidative damage by acting as antioxidants

Blood Oxygenation Level Dependent FMRI Psychology Essay

Blood Oxygenation Level Dependent FMRI Psychology Essay Functional magnetic resonance (fMRI) is the most widely used and powerful method of understanding the brain function and mapping neuroanatomy of the human brain. The most basic fMRI technique is blood oxygen level dependent (BLOD-fMRI). Paramagnetic deoxyhemoglobin in venous blood is a natural contrast agent for magnetic resonance imaging (MRI). Basic principles and methodological applications of BOLD-MRI as an introduction are presented in this article, and the relationship between neural activation and a magnetic resonance signal change is represented in much detail. Introduction Functional magnetic resonance (fMRI) is a widely recognized technique for brain mapping and providing the anatomical information of brain activity. It has been demonstrated that this method bases on the local hemodynamic changes that influence deoxyhemoglobin changes in venous blood. Furthermore, susceptibility changes produced by deoxyhemoglobin changes lead to the changes of MR signal strength. This effect is called blood oxygenation level dependent (BOLD) contract (1). High spatial and temporal resolution brain mapping can be structured by this basic method. Currently, it has become the most powerful study of brain function techniques. Compared with the traditional neuroimaging methods, including positron emission tomography (PET) and intrinsic signal optical reflection imaging, BOLD-fMRI can provide high spatial and temporal resolution sufficiently using internal concentration of oxygenation in human bodies as a natural contrast agent. Blood oxygen level dependent (BOLD) effect was firstly presented by Ogawa etc in 1990. They found that the magnetic resonance signal reduces when the concentration of oxyhemoglobin decreases. Also, their research showed that the reduction of signal not only occurs in blood, but also outside the blood vessels. Thus, they assert that this effect is caused by the property of magnetic field changes. After that, many researchers performed a large number of theoretical and experimental works to summarize the basis of BOLD-fMRI imaging. When neuron is activated, regional cerebral blood flow and oxygen consumption volume increase, but there are differences between the two increases, which is that the increase in cerebral blood flow is more than the oxygen consumption. Due to this difference, the venous oxygen concentration in active regions is significantly higher than the surrounding tissue and the concentration of deoxyhemoglobin reduces relatively. BOLD contrast has its origin in the fact that when normally diamagnetic oxyhemoglobin gives up its oxygen, the resulting deoxyhemoglobin is paramagnetic (2). Deoxyhemoglobin is a paramagnetic material which can produce local gradient magnetic field in the blood vessels and surroundings. Hence, it has effect on reducing T2. When brain areas are activated, the effect of reducing T2 decreases result from the reduction of deoxyhemoglobin. Compared with the resting state, T2 or T2* is relatively extended in local brain regions. Therefore, the signal is relatively enhanced on the T2 weighting or T2* weighting functional magnetic resonance imaging maps. Current MRI brain mapping studies all focus on off-on subtraction mode, which is the fMRI signal in active condition minus the signal under control conditions. The signal is extremely weak, and the relative increasing strength is 2%-5% generally. During imaging, the functional image of corresponding brain areas can be obtained if superimposing the high signal in different colors of active area on the high-resolution T1 weighting anatomical maps. This method is called blood oxygen level dependent contrast fMRI due to it depends on the level of oxygen in local blood vessels (1). This article reviews the basic principles and available methodological information and research on blood oxygen level dependent (BLOD-fMRI). This review begins with some basic principles on BOLD-fMRI. Furthermore, the methods for BOLD-fMRI will be described in detail including block design and event-related design. Also, the results of BOLD-fMRI studies will be presented and the advantages and limitations of the current research will be discussed as well. Finally, the key points and important aspects of the BOLD-fMRI will be summarized as a conclusion. Materials and Methods BOLD-fMRI experiment steps include: firstly, make experimental planning and determine the most optimal stimulus or task programs. Secondly, high T1 WL resolution anatomical images and a great number of original images in stimulation and rest states can be obtained by scanning. Lastly, functional active maps should be obtained by experimental data analysis. Block design bases on cognitive subtraction mode to show the stimulus task in block form. A tropical block design contains two basic tasks which are experimental tasks and control tasks, and the two intervals of blocks appear. Task-related brain activities can be understudied by the comparison of regional cerebral blood oxygen reaction through stimulation and control tasks. It is widely used in locating brain function. It is the early main method to do functional magnetic resonance imaging experiments. The advantages are simple and easy to perform tasks. However, the drawback is that the BOLD signal changes larger result in long stimulation time and the high rate of oxygen reaction. In blocked designs, regardless of stimulus presentation or task performance interdigitated with rest, observing the relationship of the time course of BOLD response to activation paradigm is possible (3). Also, more than one image can be obtained during every experimental and rest period. The signal time course should be assumed to be activated, and it can be tested. A simple example is presented in Figure 1(a). Firstly, switch on and off the visual stimulation (black and green) quickly for 10 times. It is shown that the time course of pixels follows the stimulation paradigm. However, the difference between the stimulation and time course is quite obviously (p

Analysis of the Poem, 35/10, by Sharon Olds Essay -- Poetry Analysis

In the poem, â€Å"35/10† by Sharon Olds, the speaker uses wistful and jealous tones to convey her feeling about her daughter’s coming of age. The speaker, a thirty-five year old woman, realizes that as the door to womanhood is opening for her ten year old daughter, it is starting to close for her. A wistful tone is used when the speaker calls herself, â€Å"the silver-haired servant† (4) behind her daughter, indicating that she wishes she was not the servant, but the served. Referring to herself as her daughter’s servant indicates a sense of self-awareness in the speaker. She senses her power is weakening and her daughter’s power is strengthening. It also shows wistfulness for her diminishing youth, and sadness for her advancing years. This wistful tone is again shown when she asks, â€Å"Why is it /they begin to arrive, the fold in my neck /clarifying as the fine bones of her/ hips sharpen?† (4-7). She is demanding an explanation for why she must turn older. She is jealous that as her daughter is on the threshold of puberty, becoming more beautiful, she is on the threshold of middle age, b...

Symptoms of ADD/ADHD Essay -- Disease, Disorders

You know that person; the one that can’t stay on subject, the one who will be talking then all of a sudden the conversation goes off in a totally different direction, like a squirrel searching for nuts that keeps dropping the one it is carrying because something else caught its eye. Chaotic, frazzled, impulsive, unorganized, daydreamer, procrastinator, inattentive, goof off and lazy are just a few descriptions of an adult that has Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder (ADD/ADHD). At one time ADD/ADHD was thought of as just childhood complications that did not affect adults, but since there is no cure for ADD/ADHD, adults are affected also. Most adults that have ADD/ADHD were not diagnosed with it as children, because ADD/ADHD wasn’t recognized except by a very few people that were aware of it at the time (Smith and Segal, 2012). Instead as children they were labeled as lazy, trouble makers, day dreamers and other labels and they grew into adults with those same labels and tendencies. They may have learned to adjust during the teen years but as they became adults and responsibilities and demands on their time grew, the challenges of dealing with ADD/ADHD also grew. ADD/ADHD affects 4-5 percent of all adults, more than 11 million in the United States (Barkley). When not diagnosed and treated it can impact all areas of life including work, home and social relationships. With treatment adults, and children, with ADD/ADHD can learn to compensate and overcome the symptoms and challenges they face with ADD/ADHD on a daily basis to lead productive lives. Symptoms of ADD/ADDHD aren’t the same in adults as in children and do not present themselves the same in each individual. Some common adult symptoms of A... ...d Treatment.

My 70th Birthday Speech

My Seventieth Birthday Speech â€Å"The seventieth birthday! It is the time of life when you arrive at a new and awful dignity; when you throw aside the decent reserves which have oppressed you for a generation and have stand unafraid and unabashed upon your seven-terraced summit and look down and teach-unrebuked. You can tell the world how you got there. † Mark Twain Good afternoon family and friends, I am privileged to be here today to celebrate with you my seventieth birthday. Today is a day I will remember fondly if health allows me to, for seventy is a good long time to live- I should know!In addition, it is truly something to celebrate. In the presence of everyone, my husband Alexander, my sons Alexandre and Vito, my daughters Thea-Simone and Mikaela, my 13 grandchildren and my three great grandchildren. I can proudly say, you are the reason I live today. Who I am today is a product of my earlier socialization, my experiences and my ambitions. I may be described as an in trovert, as you all know; I am quiet by temperament and flourishes in my own company and space, until I met my husband.Alexander and I met when we were in high school, we were friends first, however; a few years later the friendship has grown into something more. We both got accepted into a four year college where my major was psychology and his was biology. I graduated with our bachelor’s degree and then moved on to graduate school at Harvard University to further advance my studies to doctorate’s degree. In the latter part of graduate school I found out that, we were going to have a baby. Above all things I worried about being a good mother to our baby. I looked forward to its birth amidst the support of friends and family.Understandably, I became alarmed when my doctor spoke about his concern about the hike in my blood pressure. He cautioned me about the dangers of high blood pressure levels especially during pregnancy. I immediately changed my diet as per recommend ation and did a critical self-reflection in my quest to de-stress and restore my blood pressure to normal. It was indeed a scary time for me when my blood pressure seemed beyond control and I had to be hospitalized for treatment in the latter trimester of my pregnancy. At this point, the doctor has decided t best that I await the birth of my baby within the hospital walls, luckily, it was almost time. Looking back now, I am amazed that I found the strength to take the next step. When my daughter was born, I was devastated to learn to that, she had but a fifty-fifty chance of surviving as a direct result of the dangerously high blood pressure levels during labor. She stayed with us for a couple hours before she passed on, leaving behind devastation in her wake. I was at a low place in all faucets of my life during this time. I was crippled by grief and felt as if I had come to the end of my journey.I could not help feeling that this was a personal blow to me by God. I wondered how he could have allowed something so drastic and final to happen to me. I wondered if I was being punished for some terrible wrong that I had done. I had to dig deep inside of me to hold onto my faith in God and find the strength to pick up the pieces of my life. I was encouraged to mourn my baby by not living in denial and resume University as soon as I was able, as staying at home for an extended period as was previously planned would hinder the healing process.I conceded and returned to school hoping to fill the vacuum that the baby’s death had left inside of my soul. Had it not been for the wonderful people who entered my life and embraced me as one of their own, my coping skills would have been non-existent. Together they created a very strong support system and constantly encouraged me to hold on to my dreams and aspirations, remaining focused and surmounting each obstacle as they arose. The future was unpredictable in its entirety but I tried to remain focused and continue to believe in that which I want to achieve for myself.I knew I could not do it all by myself and I am forever grateful to my wonderful husband who stood by me through happy times and sad ones and for all the assistance I have received then and now that has helped to shape who I am today. My hard work and determination has paid off, now it is time for me to have fun. I am now retired from being the CEO of the Middleton Psychiatric Hospital and has passed down the honors to my eldest son Dr. Vito Samuda. I believe I have bored you long enough with my long speech, and I can hear the stomach growling from hunger, enjoy your meal.Guest List| Name|   | Hank Aaron|   | F.

Sociology 101 Study Guide Exam 4

Deviance 1) defining deviance is difficult and subjective (sociologists don’t agree). 2) for our purpose deviance must A) violate significant norms. B) Result in negative evaluation for reaction. 1) Conflict theory. – stress that the power elite uses the legal system to control worker and to stabilize the social order, all with the goal of keeping itself in power. The poor pose a threat, for if they rebel as a group they can dislodge members of the power elite from their place of privilege. To prevent this, the power elite makes certain that heavy penalties come down on those who’s crimes could upset the social order. 2) Functional theory- Argue that crime is a natural part of society. Stress that the sociall classes differ in opportunities for income and education, so they differ in opportunities for crime. As a result, street crime is higher among the lower social classes and white-collar crime is higher among the higher social classes. The growing crime rates of women illustrate how changing gender roles have given women more access to what sociologist call â€Å"illegitimate opportunities. † 3) Social foundations- Labeling Theory-questions who applies what label to whom, why they do this, and what happens as a result of this labeling.The significance of reputations, how they help set us on paths that propel us into deviance or that diver us away from it. Anomie Theory-concept developed by Emile Durkheim to describe an absence of clear societal norms and values. In the concept of anomie individuals lack a sense of social regulation: people feel unguided in the choices they have to make.Differential Association-a theory developed by Edwin Sutherland proposing that through interaction with others, individuals learn the values, attitudes, techniques, and motives for criminal behavior (how people learn to become criminals).Crime 1). Elements – 2). Categories- Mental illness 1) Dr. Thomas Szasz – mental illness are neither mental nor illness. They are simply problem behaviors.2) Rosenhahn study-A study done proving â€Å"it is clear that we cannot distinguish th e sane from the insane in psychiatric labels might be a solution and recommended education to make psychiatric workers more aware of the social psychology of their facilities. In this study 8 â€Å"mentally healthy† people took hallucinations attempting to gain admission to 12 different psychiatric hospitals in five different states. All were admitted and diagnosed with psychiatric disorders.After admission they acted normal again and told staff they felt fine, all were forced to admit to having t a mental illness and agree to take antipsychotic drugs as a condition of their release. All but one was diagnosed with schizophrenia. The second part of his study involved an offended hospital challenging Rosenhan to send pseudopatients to its facility, which its staff would then detect. Rosenhan agreed and in the following weeks out of 193 new patients the staff identified 41 as potential pseudopatients, with 19 of these receiving suspicion from at least 1 psychiatrist and 1 other staff member.In fact Rosenhan had sent no one to the hospital Substance Abuse1) Types of drug use-2) Social policy-3) Conflict view-Individuals and groups in society struggle to maximize their share of the limited resources that exist and are desired by humans. Given that there are limited resources, the struggle inevitably leads to conflict and competition. These struggles can lead to changes in institutions and societies as different groups come into power. Social control- The techniques and strategies for preventing deviant human behavior in any society.1) Formal- Expressed though law as statues, rules and regulations against deviant behavior. Usually carried out by those in a position of power and/or authority such as a police officer, judge, or principal of a school.2) Informal- Denominates customs, traditions, norms and other social values inherited by the individual. Informal sanctions may include ridicule, sarcasm, criticism and disapproval. In extreme cases sanctions may in clude social discrimination and exclusion. Prejudice- An attitude or prejudging, usually in a negative way.Discrimination1) Individual- Treatment or consideration of, or making a distinction in favor of or against, a person based on the race, class, group, or category to which that person or thing belongs rather than on the individual.2) Institutional- The unfair, indirect treatment of an individual embedding in the operating procedures, policies, laws, or objectives of large organizations. Can occur without conscious cause, is often subtle and nearly invisible, reinforced by the interrelationship of social institutions.Example- jobs not hiring people under the height of 5’4† which eliminates most Mexicans and women, or in other countries women aren’t allowed to participate in some religious activities or government. Post-Industrial Society- Society based on information, services, and high technology, rather than on raw materials and manufacturing.Economic System s1) Capitalism-An economic system characterized by the private ownership of the means of production, the pursuit of profit, and market competition.2) Socialism-An economic system characterized b the public ownership of the means of production, central planning, and the distribution o goods without a profit motive. Genocide- The attempt to destroy a group of people because of their presumed race or ethnicity (ethnic cleansing). Minority-People who are singled out for unequal treatment and who regard themselves as objects of collective discrimination. Plessey vs Ferguson- Decision by the US Supreme Court that confirmed the principle of â€Å"separate but equal† and minority segregation.Brown vs Board of Education-This case took on segregation within school systems, or the separation of white and black students within public schools. Up until this case, many stats had laws establishing separate schools for white students and another for blacks. This landmark case made those laws unconstitutional. This case set the foundations for the civil rights movement. Exploitation Theory- occurs when one social group is able to take for itself what is produced by another group.The concept is central to the idea of social oppression, especially from a Marxist perspective, and can also include noneconomic forms, such as he sexual exploitation of women by men under patriarchy. Amalgamation-(melting pot) all groups should combine their traditions calues and characteristics with one another to create a new group. Assimilation-The loss of a subaltern group’s native language and culture under pressure to assimilate to those of a dominant cultural group.Contact Hypothesis-This is the principle that brings people together who are in conflict (or where one is bullying the other), the conflict will subside as they get to understand one another.Power1) Authority-Power that people consider legitimate, as rightly exercised over them; also called legitimate power.2) Tradition al-Those who exercise authority do so because they continue a tradition and support the preservation and continuation of existing values and social ties. For example Queen is Head of States in Britain, a position she inherited on the basis of traditional rules of succession for the monarchy.3) Rational Legal- Those in authority give orders (and expect to be obeyed) because the office they fill gives them the right to give orders. Anyone who fills the same position has the right to issue orders. Orders are only to be obeyed if they are relevant to the situation in which they are given. Example, a teacher orders â€Å"complete your homework by Thursday† the order is expected to be obeyed, but if the same teacher asked the student to go get her milk from the store, they wouldn’t be expected to obey.4) Charismatic-People obey because of the personal qualities of the person doing the telling. Well-known charismatic figures include Jesus Christ, Hitler, and Chairman Mao. How ever, charismatic figures may arise in any social grouping and such people assume positions of authority over others on the basis of personal qualities of leadership b other group members.5) Coercive-People forced to do as they are told under threat of punishment. For example a prison or a school classroom.6) Renumerative-Power rest on the material means provided by money or some other reward which the members desire and the organization controls. Government-Political authority; a group of people who have the power to make and enforce laws for a country or area.1) Monarchy-A state or nation in which the supreme power is actually or nominally lodged in monarch. The head of state is often for life or until abdication.2) Democracy-Have the consent of the people. The officials xercising power have legitimate authority because they have been elected, and the mechanism for changing the government is through peaceful and regular elections.3) Oligarchy-Political power effectively rest with a small, elitre segment of society. Greek for â€Å" few rule†4) Totalitarianism-The state regulates nearly every aspect of public and private behavior.5) Dictatorship-A government headed by a dictator or more generally any authoritarian or totalitarian government. Power Elite-C. Wright Mill’s term for the top people in U. S. corporations, military, and political who make the nation’s major decisions. Types of Work-
