Biology :: Biology

Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics. These characteristics include cellular organization, METABOLISM, response to stimuli, development and growth, and reproduction. Furthermore, the information needed to control the expression of such characteristics is contained within each organism. FUNDAMENTAL DISCIPLINES Life is divided into many levels of organization--atoms, molecules, cells, tissues, organs, organ systems, organisms, and populations. The basic disciplines of biology may study life at one or more of these levels. Taxonomy attempts to arrange organisms in natural groups based on common features. It is concerned with the identification, naming, and classification of organisms. The seven major taxonomic categories, or taxa, used in classification are kingdom, phylum, class, order, family, genus, and species. Early systems used only two kingdoms, plant and animal, whereas most modern systems use five: MONERA (BACTERIA and BLUE-GREEN ALGAE), PROTISTA (PROTOZOA and the other ALGAE), FUNGI, PLANT, and ANIMAL. The discipline of ECOLOGY is concerned with the interrelationships of organisms, both among themselves and between them and their environment. Studies of the energy flow through communities of organisms and of the environment (the ecosystem approach) are especially valuable in assessing the effects of human activities. An ecologist must be knowledgeable in other disciplines of biology. Organisms respond to stimuli from other organisms and from the environment; behaviorists are concerned with these responses. Most of them study animals--as individuals, groups, or entire species--in describing ANIMAL BEHAVIOR patterns. These patterns include ANIMAL MIGRATION, courtship and mating, social organization, TERRITORIALITY, INSTINCT, and learning. When humans are included, biology overlaps with psychology and sociology. Growth and orientation responses of plants can also be studied in the discipline of behavior, although they are traditionally considered as belonging under development and PHYSIOLOGY, respectively. Descriptive and comparative EMBRYOLOGY are the classic areas of DEVELOPMENT studies, although postembryological development, particularly the aging process, is also examined. The biochemical and biophysical mechanisms that control normal development are of particular interest when they are related to birth defects, cancer, and other abnormalities. Inheritance of physical and biochemical characteristics, and the variations that appear from generation to generation, are the general subjects of GENETICS. The emphasis may be on improving domestic plants and animals through controlled breeding, or it may be on the more fundamental questions of molecular and cellular mechanisms of HEREDITY. A branch of biology growing in importance since the 1940s, molecular biology essentially developed out of genetics and biochemistry. It seeks to explain biological events by studying the molecules within

Censoring Student Publications Persuasive Essay Essay

Imagine that you are a high school student and have just received the newest edition of your school’s newspaper. As you are flipping through the pages, you discover a terrible article written about you. How would you feel? Recently, there has been much debate on whether high schools should be able to regulate the content of student publications, such as newspapers and magazines. Censoring student publications would be beneficial because they may contain inappropriate things. Also, it would be favorable because the material in student publications may be offensive to its readers and the text may bepoorly written. Because of this, high school officials should have the right to control the content of student publications. First of all, student publications should be censored because they may be filled with inappropriate content. Some high school students are not mature enough to determine whether certain subjects and language are usable. Without censoring student publications, students may publish something with an inappropriate subject. Since it is used throughout today’s entertainment, they may also use vulgar language. It is not appropriate for school, so high school officials should be able to censor student publications in case it is used. As a result of inappropriate subjects and vulgar language, the content of student publications may be offensive to its readers. If a student publisher does not like a fellow student, he or she may publish an article about that student. Of course, it will be something terribly offensive. Since student newspapers are given to the entire student body, practically everyone will see it. This will lead to a higher chance of bullying. Bullying is already widespread, so it does not need to be increased by angry, careless teenagers. Lastly, most high school students are not good enough writers to publish a newspaper or magazine. Students’ articles will not always be grammatically correct and presentable. Their research will be insufficient because they do not do enough research about most topics and write mostly off the top of his or her head. The articles will also be bursting with bias. Most students are not able to write an article without including bias because they are not mature writers at his or her age. Because of this, student publications should be censored. In conclusion, high school officials across the nation should have the right to control what goes into his or her school’s newspaper or magazines. Because of immaturity and carelessness, students may publish an article about an inappropriate subject and include crude language. Content of student publications may be offensive and increase the risk of bullying. Also, the newspapers and magazines may be poorly written due to the lack of writing maturity. It is essential to students’ wellbeing that a law be passed that allows high schools to control their student publications for every school in the United States not just Hazelwood School.

An Argument of Existentialism in ‘The Metamorphosis’ by Franz Kafka Essay

Argument: A person’s will to live is strongly linked to the opinions of loved ones have of that person. While some persons allow the will of their lives to become influenced to the opinions of their loved ones, others do not forget to factor the ideals of human existentialism. In order to appropriately approach the point brought across, one must factor in the underlying tone of the existentialist values of ‘The Metamorphosis’ as written by Frank Kafka. Although many existentialist philosophers hold conflicting values across the board, there are many key traits that follow existentialism. Therefore, I am inclined to, due to my level of understanding remain impartial towards both sides of the argued statement. Humans, as sentient beings, have free will and are responsible for the effects of what they decide to do. Existentialism also rejects the concept of ‘human nature’, a generalization that has become popular in attempting to identify objective external truths rather than the subjective for the individual approach. Thirdly, I say this because existentialism shows the indifference of the world towards us. Firstly, we all possess free will as independent entities apart from our society. As Gregor is dehumanized by his transformation, his family quickly deserts and rejects him of his former place in the household. The transformation can be seen as dehumanization as Gregor loses his human aspects to his self-sacrificial working ethic due to his family’s wages. One must make the balance between himself and society. When Gregor chooses work over himself, he quickly loses his humanity, hence, the transformation. Although being alienated from his family through his dehumanization causes him to ultimately lose his will for life, Gregor is yet a prime example of how free will creates a ‘cause and effect’ ripple due to the individual which is not influenced by another’s opinion but one’s subjective tastes. Additionally, a generalization cannot be approached for this situation. Existentialism as whole, strives to reject the idea of a human nature obtained by the external objective truths that cannot be applied to the subjunctive self. Instead, humans are radically liberated by their free will in order to shape their own life and defy any generalized ‘nature’. This is not seen in Gregor’s life or in Kafka’s novel. Irregardless, the existentialist value must be factored in an argued due to the underlying tone of the philosophy throughout the novel. Moreover, this approach dictates the world’s indifferent existence towards human beings. As possibly symbolized by Kafka where the household represents society’s indifference to its people, the Samsa family never cared for Gregor as the universe does to society. The absurdist branch of existentialism is then clearly revealed throughout the novel. The absurd nature of the novel highlights Gregor’s quest for purpose, for which he has lost due to the world’s indifference. It can only be here that existentialism can justify as an appropriate response. However, for some, this might not be a worthwhile approach due to the subjective nature of the mind. In conclusion, I remain indifferent to both sides due to the inability of existentialism to pinpoint whether or not this is appropriate. Human beings have free will, and this philosophy rejects the ideal of the objective truths of ‘human nature’. The will may be affected by absurdist, but infinitely varying across the board.

Purpose of correctly receiving Essay

1.  Conference calls This function allow us to have a conversation with more then one person. This would be use when managers want to talk about important subject with other brunches. Transfer This function allow to transfer caller to another department. It can be used when we the caller want to speak with the manager or person from different department. 2. Prepare a brief report advising people on: How to follow organisational procedures when making and receiving telephone calls The purpose of giving a positive image of yourself and your organisation when making and receiving telephone calls. If possible, use specific information from procedures in your own organisation (or one that you are familiar with). Almost every business have procedures how to answer or receive telephone calls. When the person is answering the phone is automatically responsible for positive or negative reputation of the business, that’s why is very to follow those procedures promptly to achieve a professional standards. Answering a call from my customer I always answering after one or two rings, I have pen and paper ready just in case I need to make a note or take a message. Then I politely greeting a caller giving my name and company, then  asking how can I help, if the call is not for me I am taking message, writing the caller name and message. I always ending the conversation with a summary just in case I understand correctly every part of the conversation, then politely thanks for call with good bye and hang up. Giving positive image is also important, because this depends weather customer will stay or go somewhere else. We can create a positive image if we will deal with callers efficiently, which means we have to know exactly what we are doing and how to use phone system. I would create a positive image with positive attitude towards all customers. I would answer the phone with a smile and kindly greeting. I would also try to identify the callers and his needs, the I would deal with it with polite manners and I would try my best to help. Secondly I would speak naturally with sensible speed to make sure the caller understand properly, then I would repeat information if necessary and summarise all the points from the conversation with the caller. Lastly I would thank the caller for his call and his time then end the conversation appropriately. If we fail to give a positive image during a phone conversation this can be very harmful for the business even more the business cane loose lots of money which could effect employees as well. The business can have a bad reputation which means that the customer will not consider cooperation with the business in the future. Section 2 – Understand how to handle mail 1. Explain the purpose of correctly receiving, checking and sorting mail and packages (both incoming and outgoing). Mail is important for successful business. It is used to transfer material, equipment and invoices from suppliers to business by post, secondly is used to provide important documents, invoices or products to the customers. One or more people could be responsible fro receiving, checking and sorting mail and packages. It must be done very carefully, otherwise the mail could not reach the recipient on time and the consequence could be that the recipient will not pay the outstanding invoice on time and could be charged for late payment. Poor mail handling could lead to loss of important documents/invoices, delays in mails, delivered mail to wrong person, additionally payment could be lost and materials or parts not being delivered on time. Finally poor mail handling could lead to dissatisfied customers (they could leave), to loss of money and sometime to business closure. 2. Complete the table below with the following information: At least two examples of internal mail services that are available to organisations At least two examples of external mail services that are available to organisations Internal mail services External mail services 1. Internal post – it is used to deliver mail between departments and branches, is sent in unsealed A4 envelopes. Confidential letters are labelled. 1. Royal Mail. This is most popular mail service in Uk. It offer wide range of mailing option to suit customers needs. 2. Intranet – mail is circulate electronically. 2. P4D is a private courier service. It help find a right courier service for urgent, big and heavy items. Sometimes is cheaper then Royal Mail.

Macbeth Act 5 Scene 3 Essay

In William Shakespeare’s Act 5 Scene 3 of Macbeth, a complete different side of Macbeth is revealed. In the beginning of the play Macbeth is a man who cannot even stand up for himself, and a man who completely relies on his wife to make major decisions. Then the very next day Macbeth becomes a man who murder, the king Duncan, and then two servants, and later his best friend Banquo. This man, Macbeth, is a psychopath, he see’s s ghost of Banquo during a dinner banquet. Finally Macbeth even kills a defenseless woman and her innocent child. Macbeth’s dissent to madness becomes completely evident in Act 5 Scene 3. This scene takes place in the castle of Dunsinane and is extremely important for it revels Mactheth’s change over the course of the play and his character. In this scene Macbeth has totally become a tyrant king who is filled with anger, hate and cockiness. In the beginning of the scene he takes his anger out on the messenger by calling him a â€Å"creamfaced loon† (Act 5. 3. 12) This response to the messenger is important for it shows how Macbeth is filled with rage and how he is a tyrant. His abuse of power as king is also revealed when he becomes enraged at the doctor by saying â€Å"throw psychic to the dogs†. This shows his impatience with the doctor for not being able to curing Lady Macbeth. (5. 3. 57-78) Macbeth continues to insult the doctor. He says to cure â€Å"cleanse the bosom of the perilous stuff†. The doctors is very insulted and states that profit again will never motivate him to come back to help Macbeth. Also in this scene Macbeth acts oddly, for example he wants to wear his armor much before the battle starts. Macbeth truly acts like a tyrant in this scene. He tells his assistant Seyton to â€Å"hang anyone who talks of fear†. (5. 3. 42) Macbeth’s interactions with others such as the doctor and messenger and Seyton show his irrationality and even allude to his insanity. This scene in Macbeth is very important for it shows the character of Macbeth which confirms his tyranny and how he is not fit to be king. Finally this scene shows how Macbeth is the sickness for Scotland. This scene also shows the importance of Macbeth being overthrown by Malcolm so that the tyranny caused by Macbeth would end.

Global Inequalities

Group A, Class 1 Introduction to Sociology Final Essay Which of the following perspectives offers the most convincing explanation for the existence of global inequalities: modernization theory, dependency theory or world-systems theory? 4 July 2012 Which of the following perspectives offers the most convincing explanation for the existence of global inequalities: modernization theory, dependency theory or world-systems theory?Globalization has had both a positive and negative impact throughout the world. An interconnectedness within the world where complicated issues can arise creating an unevenness that can contribute to a societies as well as the individuals happiness in life (El-Ojelli, 2006:p1). The negative impacts of globalization can be seen as inequalities spread throughout the world today.This essay will first explore global inequalities, next the three main perspectives of global inequality will be compared including, modernization theory, dependency theory, and world syste ms theory; following this comparison will be the argument that the dependence and world systems theory are very similar and that they are the two theories which best explain the existence of global inequalities. Global inequality can often be a topic that is overlooked in core countries such as the United States and Western Europe. However, global inequalities can be found in many peripheral countries like Africa as well some Latin American countries.Inequalities can be measured in various ways. These methods can include the GDP (gross domestic product) and GNP (gross national product) as well as HDI (human development index). GDP refers to the income earned by the value of goods and services produced by the people who live within the countries borders, GNP refers to the capital such as foreign earnings from any corporations, businesses or individuals outside of the country, where as HDI offers more in-depth measurements of inequalities such as life expectancy, education, standards of living as well as human satisfaction (Macionis and Plummer, 2012:p 286).Some inequalities in the world include areas like, income, wealth, poverty, literacy, crime, drugs, gender inequality as well as health related issues. Because of global inequalities between the rich and the poor, humans who are poor experience poverty, poor sanitation, and world hunger (Macionis and Plummer, 2012:p 306). Even though the world’s wealthiest countries are becoming wealthier, global inequalities are still growing. World hunger and poverty is a couple of the largest issues in the world, about twenty percent of the worlds population lives on one percent of the worlds income (Macionis and Plummer, 2012:p 285).The global economies development has increased which can be seen as a positive, however, the rise in the economy only goes to the rich creating larger barriers between the rich and the poor societies (Macionis and Plummer, 2012: p309). These inequalities can be found in many third world countries, where often a high population, low life expectancy and poor housing can be found. Among the global inequalities comes the capital from which is made in under developed countries and has divided the wealthy nations from the poor.A few models of development in global inequalities can be found, these include modernization theory, dependency theory, and the world systems theory. The first theory explained is the modernization theory. The modernization theory is much different than the last two perspectives on models of development. In this theory societies are brought together by modernization. There are four phases of modernization which show the different areas of growth, these phases are a traditional stage of society, a take off stage, a drive to technological maturity, and a stage which shows a high mass of consumption (Rostow,1990:p 4).Throughout these phases of modernization in societies where this theory has been introduced the development in the world is due to adva ncing industrial societies taking over societies that would have been living in a more traditional society (Macionis and Plummer, 2012:p 306). The first phase of modernization according to Rostow (1990:p 4), the traditional stage refers to a country that did not have much production because of little or no technology within the country.The second phase, the take off stage, is essentially the building of the economic structure and technological advances provided by a foreign power within the underdeveloped country, and third the drive to technological maturity is when these economic and technology building blocks advance about 40 years and there is now a mature economy of imports and exports, and last the fourth phase of mass consumption in which a modernized society in the twentieth reaches the maturity phase and the international economy reaps the benefits (Rostow, 1990:p 12).Over time some societies become more modern than others creating an unequal balance among other states glob ally. It is the thought that the modernization theory in some societies, are left behind because of advances in technology and within the economy also (Macionis and Plummer, 2012:p 306). Rostow (1990: p12) suggested that the modernization theory is created by an outside government or corporation to introduce new technologies and build industries to make money.As the four phases of modernization are explained above, it is simple to understand how these societies built upon modernization can create global inequalities and unequal balance within an underdeveloped society. However, the modernization theory is not only based on industrial and economic progress but also on political progress as well (Kamrava, 2000: p30). Governments from other states such as the USA or UK among others can become powerful when using cheap labor and production through these industries creating a higher economy for the western states opposed the under developed states.Some criticisms of modernization can be the loss of a country’s traditions, the culture, and religion practiced within the country (Kamrava, 2000: p31). Although the modernization theory is based on ideas of development in an under developed country, the dependency theory is a theory structured and very different than that of the modernization theory. The dependency theory is in which under developed countries such as Africa are being exploited by slavery and colonialism (Macionis and Plummer, 2012: p306).Most under developed countries do not grow out of this phase; instead they depend on the larger capitalist countries for support (Macionis and Plummer, 2012: p306). These under developed countries often do very poor after such exploitation creating high poverty in the world. In various poor countries such as Africa where the British and the French integrated through society, the idea of development was when the problems of global inequality was defined due to both the economic and social failures in Africa (Fergus on cited in India and Ronald, 2002: p146).Some colonized countries are often left under developed and lack in basic necessities to live a happy and satisfied life. The under development was caused by colonialism and the forthcoming international division of labor, offering low cost labor to create industries for western societies (Kamrava, 2000: p32). With various industries being built and the creation of jobs for those who lived in exploited countries, workers in these countries would still not reach expectations of higher standards of living and still do live on very little money in this very day and age.With the building of industries, western society has reached their development goal, causing the under developed to depend on western societies more so, all the while the western states earn capital and the rest of the third world countries remain under developed (Kamrava, 2000: p32). Under developed countries were mostly at one point colonized; therefore the countries were built by developed nations who have greatly mislead the developing countries. The developing countries have had the misfortune to then be led to work and serve the developed nations by producing goods and a lower price, thus, creating global inequality.The international market was the leading force in the dependency theory, there the developing countries worked to meet the needs of the international economy instead of meeting their own needs (Kamrava, 2000: p 32). Developing countries were depending greatly on the developed countries themselves. The developed countries helped the developing countries financially in order for the developing countries to keep production flowing. Developing countries were given loans to aid the promotion of industrialization in order to keep continuing flows of exports (Kamrava, 2000: p33).With the aid of the developed countries, the developing countries would keep not only exports flowing but capital flowing as well. According to dependency theorists, capi talism was the key reason to keep exports flowing from third world countries to the west (Kamrava, 2000: p33). Capitalism, the financial profit of purchasing or the trade of goods is also a key feature in the world systems theory. World systems theory or also known as world system analysis is based on an approach to earned capital in a world system rather than through individual nation states, by leaning on this theory the developed countries remain the super power.The world system theory is based on the world’s economy within its relationship to core and periphery countries, creating inequality throughout different parts of the world (Macionis and Plummer, 2012: p 306). Core and periphery as well as semi periphery countries fall into what is called an economic zone, some core countries include the United States, and United Kingdom as well as Western Europe, Periphery would be countries in Africa and also a few in Latin America, while semi periphery would fall under countries such as Mexico or Brazil.Within the world system theory the semi peripheral countries remain neutral, they are neither a rich developed country nor are they under developed and the core countries are categorized as the developed countries, while the periphery are the under developed leading to the economic power that places developed and under developed countries in an unequal world (Macionis and Plummer, 2012: p 306). The world systems theory is without doubt a capitalist economy in which the developed countries dominate.Core countries remain strong within their borders and internationally, whereas the peripheral countries have weak economies because they depend on the core countries for international trade (Randall and Theobald, 1998: p145). The core and periphery countries both have their own areas of expertise when it comes to who does what in these industries. The world system theory is focused more on advanced core economics drawing attention on manufacturing and banking, whi le the periphery areas are focused on the production of goods (Randall and Theobald, 1998: p145). These areas of focus are also directed to everyday human interaction.With the food, music, and clothes people buy on a daily basis, these areas are connected to a world system. Clothing for instance can be connected to the world system, for example, when buying clothes in the UK which are beforehand manufactured in areas such as Africa or Mexico among other countries in the world (Kardulias, 1999: p300). Out of the above three theories, not only does dependency and world system theory result in the best explanation of global inequalities but they are built off each other and become like one, therefore these two theories are very much alike and similar in certain details.The dependency theory and world systems theory are similar, they both have a core and periphery area, however, the world systems theory looks at one more area, the semi periphery which is a more neutral zone working with both the core and periphery countries (Randall and Theobald, 1998: p 144). Besides the difference of economic zones in these two theories, the dependency and world systems theory are always in favor of the dominant developed countries, which are interested in economic and political power. The core ideas in both theories are very much related and together both theories can be the reason for global inequalities.An article in The Economist describes how global capitalists believe that the gap is widening between the rich and the poor, the reason for global inequality could be due to an unjust trading system (The econo mist, 2004). Within the three theories on global inequality, the modernization theory, dependency theory, and world systems theory, the modernization theory could be held accountable for global inequality with its ideas of advancement in technology and industries. However, The dependency and world systems theory are in my opinion the sources of global inequality.While th e modernization theory looks into advancement in technology and development of under developed countries, the dependency and world systems theories focus on how to gain economic and political power, which gains higher dominance in the core countries. The peripheral countries will continue to depend upon the dominant core countries until a new and justified trading system is implemented. Word Count: 2021 References Inda, J. and Rosaldo, R. (2006).

Wine Market (ALDI Group) Case Study Example | Topics and Well Written Essays - 3000 words

Wine Market (ALDI Group) - Case Study Example In 2008, ALDI's global revenues reached an estimated $65,700.0 million in tendered sales. Distribution of revenues across markets reveals growth in some regions of the world, and retraction in others. Adequate analysis of sites for aggressive advancement of wine varietals within ALDI stores across the board requires data on the overall picture of the various market regions and segmentation analysis of both the wine industry and its customers, for future integration of operations and knowledge sharing with industry partners toward realization of the Group's planned expansion in this product area. One of the strengths of ALDI's German based operations has been the Group's flexible approach to strategic opportunities during moments of economic downturn. A company known for its vision of offering the 'cheapest' high caliber products to its markets, ALDI has brought its 'home,' national and international brand grocery product lines to customers at the lowest possible prices while retaining the select-assortment concept indicative of specialty stores. ALDI's philosophy of grocery retail is based on a 'less-is-more' approach; from supplier selection to store location development and operations, each step in the distribution to market chain is managed to facilitate savings substantial enough to impact the everyday lives of consumers. The Group is reliant upon a tri-partite model of conducting retail business, which includes concentration on: 1. Purchasing power which translates to customer savings, by a large grocery retailer with focused attention on a limited number of 1,400 grocery and household items, of which are mostly ALDI 'select brands'; 2. Streamlined operations that enable the corporation to reduce costs; 3. Adherence to stringent quality standards dedicated to matching or exceeding the leading national brand in taste, appearance, and/or performance. In the context of the most recent global financial crisis, ALDI is looking for ways in which to expand its market share in the retail wine sector. Strategic planning toward this vision must acknowledge points of saturation in the wine market, as well as the total competitive picture in the retail grocery industry. For instance, ALDI's market share in its home country, Germany, has actually seen a reduction recently due to a high level of competition from other compatriot corporations. In efforts to retain the Group's 19% share of the German national market, the stores have begun to offer shoppers more in the way of international brands, and better incentives through semi-weekly promotions in order to capture a larger segment of the middle-class consumer population. Despite the challenge faced at home, ALDI's operations in over 15 other countries continue to be successful, and while hit and miss in 'hot' markets in Eastern Europe sustained by youth demographics, ALDI has recently opened stores in Hungary and Poland. The Commonwealth countries of South Pacific offer a similar demographic operations in Australia now
