First Poem for You Essay

The Shakespearean sonnet â€Å"First Poem for You† has an iambic pentameter and consistent rhyme scheme. Every other line represents a true rhyme – the final accented vowels and all succeeding consonants or syllables are identical. For example the words â€Å"complete† and â€Å"neat† (Addonizio 1, 3). Every line of the poem has a basic stressed and unstressed syllable format, except the last line. The extension of the last line â€Å"but touch them, trying† implements a longer stress (14). I believe this has definite meaning to the structure of the poem. In addition, the final verse of the poem is the longest line. In relation to the word â€Å"trying†, I believe that the longer stress and length in the final line of the poem emphasizes the woman continuing to mend the relationship with her boyfriend. The theme of the poem is about love and desire, a woman who cares for her boyfriend seeks to mend the brokenness in their relationship. The title of the poem, â€Å"First Poem for You†, is simplistic and straightforward. Nevertheless, it has direct meaning and relation to the poem. There is a woman writing to her boyfriend about her feelings towards him. She likes to touch his tattoos, have sexual intercourse, yet she recognizes the pain between them and states that â€Å"such permanence is terrifying† (13). These split feelings cause a tone of ambivalence – conflicting feelings toward a person. She is touching the tattoos in complete darkness, which can help the reader understand her desire for her boyfriend yet the shame or timidity that is shared as well. Most shameful acts are done in the dark. Culture and society distinguish the pros of light vs. darkness. This poem does not directly reflect light vs. darkness (good vs. vil), but I believe the negative connotation the word darkness holds, transcends into this poem. If she was touching her boyfriend in the light the poem may have a more optimistic mood. However, darkness is usually related to death, therefore having a pessimistic mood. Furthermore, the connotation of death demonstrates a more in depth meaning of verse 11, â€Å"you’re seared to ashes†. This is a representation of the boyfriend’s death. Perhaps, he is burned alive, but I believe it refers more to him being cremated. Either meaning the reader interprets, the writer wants the reader to understand that the tattoos will remain until death. This is important because I believe the lasting of the tattoos reflect the â€Å"until death do apart† affections the woman has. This brings us back to the last phrase of the poem, â€Å"but touch them, trying†. Despite the confusing feelings, the woman wants to work through the relationship till the death of one of them. Just as the tattoos will remain till death, so will her pursuit towards her boyfriend. The tattoos have many symbolic representations that help the reader understand the feelings the woman has for her boyfriend. Water and lightening are two words that have a symbolic meaning for the poem. â€Å"Lines of lightening pulsing just above your nipple, can find, as if by instinct, the blue swirls of water on your shoulder where a serpent twists, facing a dragon† (4-7). Though symbols can have multiple meanings, the tone and theme of the poem helps to point out the specific meaning behind the relationship. The girlfriend, of the guy with the tattoos, enjoys touching the tattoos when she is unable to see the guy. She knows by heart just where the lightening is pulsing. In this case, the lightening symbolizes power of love that has a pulse, just like a person’s heartbeat; a beat that can go faster or slower depending on the situation. It is instinctive for the woman to know where every tattoo on the guy, just like in a relationship, a person may know every mark or scar on the other’s body. The woman knows that just above his shoulder are the blue swirls of water, where the water is symbolizing that the boyfriend may be pure at heart. The serpent facing the dragon symbolizes the warrior in him, and it also shows he has no fear against his enemies. When I pull you to me, until we’re spent and quiet on the sheets, I love to kiss the pictures in your skin† (Kennedy, 601), means that she pulls him closer to her while they’re laying down and falling asleep, she expresses her love and care for him until there’s no more time left in the night, until it’s all spent. To kiss the pictures in his skin simply means kissing his tattoos. â€Å"They’ll last until you’re seared to ashes; whatever persists or turns to pain between us, they will still be there† (Kennedy, 601), whatever persists†¦

Should Everyone Undertake University

ASSIGNMENT: REFERENCED ESSAY TITTLE: EDUCATION TOPIC 1: SHOULD EVERYONE BE REQUIRED TO UNDERTAKE A UNIVERSITY EDUCAtion DATE: 6 JANUARY 2013 In modern life, many students choose to enter university or college after they have graduated high school because higher education is a good environment to prepare for their future. However, some others think that it is only one of causes to increase the rate of unemployment, while they just need to follow vocational training or start working to improve their skills.This essay argues that everyone should be required to undertake a university education because it gives benefit to individuals such as career opportunities with higher earnings and social benefits. One of the main reasons why people should go to university is because it is a personal investment that can improve their life’s quality in the future. In higher education, people not only learn the knowledge from books but they also acquire what they need to know for their future li fe.Potter (2006) states that â€Å"university graduates also enjoy lots of other non-market benefits, including a lifetime of better mental and physical health, stronger social networks, and higher social status†. Indeed, university education provides many opportunities and benefits. Firstly, higher education provides career opportunities for students because they can get more knowledge and experience for their jobs in the future. Lederer (2010) mentions that university students will have lower unemployment rates in an economic downturn.This means as job markets are growing up, there are hundreds of applicants for one position in a company so if people do not have a qualification from university or college, it will be hard for them to be accepted. Furthermore, individual income is also strongly related to education attainment. People who graduate higher education may earn more than others so they will have more employer provided health and pension benefits. For example, accor ding to Baum (2007) â€Å"the typical bachelor’s degree recipient can expect to earn about 61% more over 40 years working life than the typical high school graduate earning over the same period†.Some students believe that vocational training might be seen alternative program for university. However, they can still find a good job, their company will require college or university experience if they want to have a higher salary. Finally, higher education is where students build connected networks. They may meet friends and mentors that become a future contact and colleagues from all activities when learning including volunteer work, summer jobs or student organizations. The author in the article â€Å"building rapport-establishing bonds† states that developing professional connection is a skill that everyone can learn and can use easily.They can use it to bring countless opportunities to be successful. Consequently, studying higher education will make more new opp ortunities for student to have a better life and prepare for their career. Next, undertaking university education is not just benefitcal for individual students but also beneficial to the whole society. People, who have higher learning, will have awareness and responsibility for their life. Firstly, going to university is related to economic advantages of society.Baum (2007) presents: â€Å"higher levels of education lead to both higher of earning for individuals and higher taxes revenues for federal, state, and local governments†. University graduates not only pay more taxes with higher income, but they also tend to have better health and depend less on government programs and spend more leisure time with their family or on civic activities. Moreover, students who have higher education will have more knowledge and awareness in life choices and can more easily to avoid lack of money and will become a criminal. According to Dr.Hill (2005), educational attainment may lead to le ss criminal behavior and lower imprisonment rate. Thus, the number of criminals will decline so human life will be happier and people no longer worried about things such as phishing, theft or violence. Higher education is a good way to help develop the economy and society. In conclusion, everyone should be required to undertake university education because students can have the opportunity to prepare for their jobs, creating career opportunities and higher income in the future. This leads to better individual life’s quality and give more benefits for society.Overall, from reasons above, students should be encouraged to go to university to get better life and better country.

Literature Review - Forms of Business Essay Example | Topics and Well Written Essays - 1750 words

Literature Review - Forms of Business - Essay Example Because of this, an accountant must understand the different forms of business so they are able to provide the best information for the particular business. There are many different types of business structures. These include sole proprietorships, partnerships, and limited liability companies. In order for an accountant to do well with business, he or she needs to understand how each of these business structures work. Relationship of the Topic to Future Career Goals I have chosen this topic because accountants are needed all over the world. Many organizations provide many services for profit. Of course, accountants are also needed in the non-profit sector so the prospects for careers are endless. Many companies have gone bankrupt because they did not do well with their money. For example, companies like Enron, Qwest, and others had problems because they did not handle their financial affairs well. Because of this, an accountant can specialize in many different areas. An individual co uld decide to become a financial accountant, a managerial accountant or a cost accountant (Peavler, 2013). The field of accounting seems very open and it seems more dependent on an individual’s decision as to which aspect of the field they choose as a career. I wanted to investigate the different business structures and focus on the advantages and disadvantages of each one. Accounting is a basic principle of economics and can be viewed on different levels. For example, a company will use accounting, but an individual may also use an accountant to take care of everyday needs. Many people use accounting for calculating their taxes, making decisions, and understanding their stocks and bonds. This literature review will continue to develop the differences between the business structures and provide an understanding of the main characteristics and the advantages and disadvantages of each of these structures. Sole Proprietorship A sole proprietorship is generally the organizational structure that someone takes who is just beginning a start-up company. This allows the individual to have a business name and use their own social security number or register with a business number. A sole proprietorship allows an individual to operate as a business and to take all the profits. One person runs the business and therefore is responsible for any losses or debts that the business incurs. Advantages of a Sole Proprietorship The literature review provides a variety of ways that a sole proprietorship has its advantages and relates to accounting. Amato (2013) states that sole proprietorships need to do succession planning although they are the only ones running the business. Amato states that sole proprietors must understand that there is a need for them to name someone who will take over the business when they want to leave it, if they are not selling it. Hendrix (2012) states that a sole proprietorship is the easiest form of business to start because the owner and the bu siness are the same entity. LaMance (2012) states several advantages of a sole proprietorship. The owner does not have to do separate business tax forms, sole proprietors can hire employees and they can receive tax breaks for hiring people. Also, the owner of the business is the only one responsible for making decisions in the business. Disadvantages of Sole Proprietorship LaMance (2012) states that there several disadvantages of sole proprietorsh

Language analysis Essay Example | Topics and Well Written Essays - 500 words - 1

Language analysis - Essay Example 25).The reversed event sequences make it interesting, the beginning marking Sal’s present-day account of spending Christmas with his relatives in Virginia, the middle part showing Dean’s surprise and unannounced visit to Sal in Virginia, and the final part describing the events leading to Dean’s unannounced visit to Sal, bridging the beginning with the end. Kerouac focused the addressee’s attention using sequence markers depicting what came first and last. For example the phrase â€Å"It was over a year before I saw Dean again† (Kerouac, 1999, p.101) implies the present setting, continuing until Sal learned that â€Å"Dean had lived happily with Camille in San Francisco ever since that fall of 1947†¦Ã¢â‚¬  (Kerouac, 1999, p.104).The phrase â€Å"I learned that (Dean had lived†¦)† prompts a flashback in the story’s timeline on how Dean ended up in Virginia in a car with two other people. Even in the narrative’s reversed sequence of events, subtle context clues and prompts show what happened, what happened next, and what happened after that (Hooey, 2000, p. 25). Contextually this is the narrative’s sequence: Dean compulsively bought a car using Sal as scapegoat to leave her and be on the road. Meanwhile, within the year that these events happened, Sal spent time writing his book at ho me and going to school. Sometime between Christmas and New Year Sal visited his relatives and brother in Virginia, but was surprised on Christmas Day when Dean and company appeared at his brother’s doorstep. After settling down, Dean told Sal why he visited unannounced (Kerouac, 1999. Kerouac moderates narrative timeline jumps by prompts connecting indirectly-related events. Since people take contexts and subtle links using their own experiences and views, the narrative makes sense even when sequences are reversed (Underhill, 2013, pp 20-22),

An Analysis of George Stiger Criticism of Adam Smith Essay

An Analysis of George Stiger Criticism of Adam Smith - Essay Example Smith refrains from making reference to self interest in the analysis of the popular passage motives but rather resort to the phrase ‘self love’. From these two phrases ‘self interest’ and ‘self love’ a misconception can arise that the two are synonyms. Criticisms of Adam Smith The most indebted intellect by Adam’s work is Hirschman. In his work on interests and passions, there has been evidence of relationships between moral philosophical development and modern model on self interest and rationale for state theory. Adam’s article contributes much support to Hirschman’s work and emphasizes it more. There are certain instances when Smith contradicts himself. This should not be considered as failure as far as his works is concerned. Similar to his classical ideologies, Smith fronts an argument that, in order for one to get the truth, an issue being debated should be viewed from all perspectives (Miller, 1993). Clarity on this has been made on moral sentiments theory, where Adam adopts debates on commerce corruption influence, and consequently denies them to be splenetic philosophy. From Smith’s perspective, the nations’ wealth was a significant reconciliation of human’s political and social idea on fruits of commerce. From Hirschman’s idea, an argument arises that the reason to economic adventure as an independent science is because of Smith’s republican leanings. ... From the article, the dominating characters did not place themselves in a focal point with consideration on their contemporaries and predecessors. Focusing on ways authors perform their own systems of construction, they always reject the fundamentals of other authors in order to build theirs. Traditionally, economists persist that the behavior of having self interest hold particularly for activities in economics. Attempts have been made to take self interest in a broader perspective as the initial principal in analyzing the behavior of individuals. There are claims that a comprehensive approach to economics is that which can be applied to all individuals, regardless of the price behaviors or imputed prices, infrequent or recurring decisions, minor or large solutions, mechanical or emotional ends, poor or rich people, children or adults, women or men, stupid or bright, doctors or patient, students or teachers. Adam smith refrained from the fact that as much as an individual’s e conomic behavioral pattern is always predictable there always few instances when the pattern changes (Smith, 1776). Another intellect asserted that in case the universe in physical form was a subject to motional law, then the universe in moral form will be a subject to interest. In General, self interest stands out as the only motivation for human action. George Stigler conveys a message that is used by many economists as he reiterates that the quote on baker, brewer and butcher contributes to the primary principle and to the modern economics. As much the interpretation of self interest is easily floated in mind, it is a testimony of interest paradigm. Initially, the idea to pursue self interest by agents of independence would lead to

Confucian Ethics Essay Example | Topics and Well Written Essays - 2000 words

Confucian Ethics - Essay Example Confucius, the founder of Confucianism believed on a golden rule based on the belief that people should do unto others, what they would like to be done unto them His ethical code was based on humanity, love, and morality. Rather than being based on religious beliefs, Confucianism is based on a system of social and ethical principles. In East Asia, Confucianism touches on all aspects of life (Slote and De Vos 5). These include the family, education, society, and government. Although Confucianism has most of the times been grouped together with other religions such as Christianity, Islam, Hinduism, Buddhism, Taoism, and Judaism, it is not a systemised religion. According to Slote and De Vos, â€Å"a viable way of life for so many and for so long, Confucianism has sometimes been viewed as a philosophy and sometimes as a religion† (5). ... Confucius stressed that despite the fact that strict observation of traditional rituals is important, a devoted spirit and a sincere heart are even more important. He found no value in performing rituals, while a person was inhuman or lacked humanness. According to him, taking a keen look at person’s actions, motives, and preferences, then his or her real character is revealed and cannot be concealed. Confucian ethics revolve around associations among human beings. The philosophy mainly â€Å"revolves around family relationships, especially around the relationships between parents and children, between elder and younger brothers, and between husband and wife† (Yao 32-33). The Confucian belief is based on the grounds that fulfilment or responsibilities in these relationships should be done with a complete and genuine heart. However, despite revolving around the family, the Confucian moral philosophy is not restrained within the family, but also the society. Emphasis is p laced on the family because it is the foundation of peace around the world and order in the society. According to Yao (33), the Confucian â€Å"logic is that the family is the basic unit of the human community and that harmonious family relationships will inevitably lead to a harmonious society and a peaceful state†. The virtues of leaders within their families are very vital and determine how they rule organisations and a nation, since the basis of their actions, motives, and preferences is found within their family units. This consequently has an effect on a whole nation. A ruler who has intense love and devotion for his relatives, parents, friends, wife, and children is humane to the common people in the society and treats them with honour and consideration. Such kinds of rulers are

Industry Competitors. A considerable number of corporations have developed into an essential part of the period of global competition, increasing enhancement, enhanced corporate paradigms, and corporate restructure. The continuous transition from the conventional corporate framework with its hierarchical corporations to a worldwide, knowledge-founded financial system as well as intelligent corporations demands business management to realign and relocate its techniques (Oliver, 1997).

An Inch Closer to My Dream Essay Example for Free

An Inch Closer to My Dream Essay My exposure to my father’s dental practice has effectually inspired me to pursue a profession along a similar line. This dream has become an ultimate priority at this point in my life. It is my dream and I would do anything just to reach that dream, understanding the time, effort, and good work ethic that the dream requires. As a dentist, my father has specialized in implant surgery, and firsthand, I was able to see how his work transformed the lives of his patients – not only changing them physically, but changing more profoundly the way they looked at themselves and the world. I am a Korean, majoring in Art and I went to the United States to study Biology instead at California State University, Northridge. I have discovered that this degree has fully maximized my potential and it led me to the path where I am most fulfilled. Science is very essential to everyone’s existence and I cannot bear not to think critically of what is happening around us. It was very stimulating for me to solve problems of nature and life that I would wish to extend my study and earn a Master’s degree within the same field. I am very looking forward of pursuing functional anatomy, physiology, genetics, and embryology. My reason for pursuing oral biology at NYU is not merely because it is to my personal preference or liking. While that is one factor, I have also considered wanting to contribute to the betterment of Korean society in my own little way. I feel that through oral biological research, I would be able to make a dent in our social fabric, discovering new things about cures for diseases or mechanisms of seemingly untreatable illnesses. This has been a personal mission because I have had the chance to be exposed to indigent communities who are in dire need of help. Through oral biological research, I may be able to help these communities alleviate their poverty within my own sphere of influence. My volunteer work at my father’s clinic has allowed me to foster this desire to help other people authentically through the dental arts. Fortunately, I was enhance familiarity with dental procedures, including orthodontic treatment, root canal, prophylaxis, x-rays, among others. The idea alone of being able to make a difference in people’s lives, through oral biology, excites me. It makes me even more eager to pursue my course and be very competent biologist. Apart from wanting to help impoverished communities, I have also taken careful note of the level of scientific progress that Korea has attained. Unofrtunately, it is not as advanced as first world countries such as the United States. Thorugh my own contribution, I would like to see the advancement of science in my home country. I would love pursue my studies in a different university and I chose New York University to broaden my horizons, and gain new perspectives from a different environment and from different set of individuals. I believe that I can learn more by being exposed to a diverse culture and New York is the right place. Being able to study in New York, and also later work there is a great opportunity for me. Moreover, the Graduate Program in Oral Biology fits perfectly to my needs. Going through NYU’s website, I am filled with excitement as I realize that this course shall accord me with a solid foundation in the oral biological sciences, which are more specifically targetd at teaching and research. Some areas which I am particularly interested with are periodontal and caries microbiology, chemical carcinogenesis, mechanisms of mineralization, periodontal wound healing, and tumor immunology. I also believe that this school only produces the best, and I want to become the person I would be proud of in the future. This is where I should start my future. I think that exposure to various cultures shall also help me grow significantly as a person and professional. I will be able to learn how to deal with people with different backgournds, upbringing, and cultural heritage. Because I shall have the chance to interact with them frequently, I will be able to understand and respect their culture. This is very important, since stereotypes cause people to make biased decisions, which lead to social inequity. I would love to think that my enrollment in the university will help me become more impartial to race / color. I feel that the thrusts put forth by the university are strongly consistent with those that I personally uphold. I have high hopes that I will qualify to form part of this prestigious institution. It will surely be a privilege that I will take profound pride in. And because of such pride, I will work hard to excel academically. The ultimate goal is for me to become a competent professional – to be able to contribute substantially to humanitarian causes.

Anatomy And Physiology Of Blood And Heart

Anatomy And Physiology Of Blood And Heart The mechanism of the pumping action of the heart can be categorized in three phases- the generation of an action potential, conduction of the action potential and cardiac muscle contraction (action potential-contraction coupling). The action potential is generated the specialized autorythmic myocardial cells located at the Sino atria (SA) node. The potential spreads to the atria and enters the ventricles through the atria ventricular (AV) node from where it is conducted throughout the ventricles by the bundle of His and the purkinje fiber. The action potential triggers muscle contraction as it sweeps around the heart1. As the cardiac muscles contract and relax the heart beats repeatedly, in the process receiving and pumping blood, first to the lungs then to the rest of the body. As it leaves the heart, the blood carries with it oxygen and nutrients to the body and brings back metabolic wastes from the body cells1,2. However, much as it supplies blood to the rest of the body, the heart itself needs blood to support its metabolic activity. The heart is thus supplied by the coronary arteries which branch off from the aorta. Reduction in the volume of this coronary flow can greatly impair the pumping action of the heart and if not treated, can cause heart failure. A number of treatment options ranging from surgical to drugs are available2b. THE CARDIOVASCULAR SYSTEM The cardiovascular system is an organ system responsible for distribution of nutrients and oxygen to the bodys cells and removal of metabolic byproducts from the cells. It consists of the following: Blood which carries nutrients and oxygen to the cells and metabolic byproducts away from the cells The blood vessels which are the pathways through which blood flows The heart which receives and pumps blood. Embedded in the heart are valves that control blood flow and ensure that blood flows in a specified direction3,8. THE HEART In brief, the heart is a muscular organ enclosed in a double walled sack called the pericardium. It is about the size of a fist and weighs between 250 grams and 350 grams. It is located within the medial cavity of the thorax between the second and fifth intercostal space, just on the superior surface of the diaphragm, anterior to the vertebral column and posterior to the sternum7. The heart is divided in four chambers, the right and left atria, the right and left ventricle. The circulation process is such that the right atrium receives blood from the rest of the body through the venacavea and feeds it to the right ventricle which pumps it to the lungs through the pulmonary artery to be oxygenated. Blood from the lungs comes back to the left atrium through the pulmonary vein and finally to the left ventricle. The left ventricle pumps blood to the rest of the body though the aorta and arteries7,1. The Mechanism of Heart function The most important function of the heart is to pump blood. The mechanism by which the heart pumps blood can be understood by examining the events that lead to cardiac muscle contraction. The contraction process starts with the generation of an action potential from the sinoatrial (SA) node giving rise to a depolarization wave. The wave spreads through the atria, entering the ventricles through the atrioventricular (AV) node and is conducted throughout the ventricles by the bundle of His and the purkinje fibers1. Generation of action potential. The heart is composed of two kinds of cardiac muscle cells- the contractile and autorythmic cells. The contractile cells are responsible for the mechanical work of pumping and therefore form the bulk of the cardiac muscles. However, these cells need to be excited before they can contract. Highly specialized autorythmic cells are responsible for generation and conduction of the excitation signal-the action potential1,3. These autorythmic cells are found in specific regions of the heart that include: The SA node. This is a small region located at the upper wall of the right atrium. The AV node. This is a bundle of the autorythmic cells found at the lower wall of the right atrium, near the septum that separates the atria from the ventricles. The bundle of His. This is a bundle of specialized conductive cells that originate from the AV node and runs down the septum between the ventricles. It separates into the right and left bundles serving the respective ventricles. The purkinje fiber. These can be regarded as terminations of the bundle of His. They spread over the base of the ventricles.The locations of the autorythmic cells are the origin and pathways of the action potential3. The cardiac action potential The SA node is the pace maker of the heart. It sets the frequency at which the heart beats. Looking at the cardiac cell, the action potential starts by the reorganization of the intracellular and extracellular concentration of potassium, sodium, chloride and calcium ions due to changes in the cell membrane permeability. A graph showing a typical myocardial cell action potential is shown in figure 1 below. Figure 1: Cardiac cell action potential. Source4: As in the graph, the different phases represent different stages of depolarization of the cardiac cell. Phase 4: In this phase, the cell is at rest. In the resting state, the cell membrane is more permeable to potassium and therefore the resting potential is more or less equal to the potassium equilibrium potential (-90mV). Phase 0: As the potential slowly rises, the voltage-gated sodium channels open leading to a rapid influx of potassium into the cell causing rapid depolarization. At the same time, the membrane permeability to potassium slowly reduces as the potassium channels close. This process takes the membrane potential to around +20Mv before the sodium channels suddenly close. Phase 1: On inactivation of the sodium channels, potassium continues to leak out of the cell and chloride ions go into the cell causing a small downward deflection of the action potential. Phase 2: At this stage, there is increased permeability of the membrane to calcium ions. The inward calcium movement is balanced by an outward movement of potassium ions accounting for the relatively flat phase 2. Phase 3: An increase in the permeability of potassium outweighs the inward calcium current and eventually tips the potential of the cell. This is the repolarization phase and the cell goes back to its resting potential, phase 43,4. Excitation-contraction coupling As described in muscle contraction, the action potential-contraction coupling is due to the release of calcium from the cells sarcoplasmic reticulum. The calcium combines with troponin which regulates the tropomyosin, removing it from the binding site. This allows myosin to bind to actin thus making the muscle to contract3. The cardiac cycle The depolarization and repolarization of the cardiac cell described above triggers the contraction and relaxation to the atria and ventricles of the cell. The cardiac cycle is divided in two main phases, diastole which is the period of relaxation and systole which is the period of contraction. Systole. During this phase, the depolarization wave starts from the SA node, spreading first through the atria and causing the atria to contact first. This forces blood from the atria to the ventricles. At this time, the atrioventricular valves are open while the pulmonary and aortic valves are closed. The depolarization wave then enters the ventricles through the AV node, spreading over all the ventricles via the specialized conductive bundle of His and the purkinje network. This causes the ventricles to contract forcing the blood to the lungs through the pulmonary vein and the rest of the body through the aorta. Here the atrioventricular valves close while the pulmonary and aortic valves open5,3. Diastole. After contraction of the atria, the cells are repolarized. This allows the atria to relax thus allowing blood to flow into them through the vena cavea. After the ventricular contraction, the ventricles also relax awaiting to be filled with blood from the atria5. THE CIRCULATORY SYSTEM The circulatory system is part of the cardiovascular system and is divided into the pulmonary circulation and systemic circulation. The pulmonary circulation transports deoxygenated blood from the heart to the lungs and returns oxygenated blood from the lungs to the heart9. The systemic circulation transports oxygenated blood from the heart to the rest of the body and brings back deoxygenated blood from the body back to the heart9. Deoxygenated blood enters the right atrium from the vena cava and flows through the tricuspid valve into the right ventricle. It is pumped from the right ventricle through the pulmonary semilunar valve into the pulmonary arteries which go to the lungs. Oxygenated blood returns via the pulmonary veins and enters the left ventricle through the mitral valve. It is the pumped through the aortic valve, to the aorta then through the arteries to the rest of the body. It is evident that oxygen is very important in metabolic activity of the body cells3,9. Transport of oxygen by the cardiovascular system The red blood cells. One of the functions of the cardiovascular system is to distribute oxygen around the body. Oxygen is carried in blood by the red blood cells. Understanding the structure of the red blood cells will help us to understand how it is able to carry oxygen. The molecule of a red blood cell is composed of four polypeptide chains with each polypeptide chain having an iron-containing heme group. Each of the four iron atoms can combine reversibly with oxygen according to the equation: O2+Hbà ¢Ã¢â‚¬  Ã¢â‚¬ HbO2. It is therefore possible that each molecule of hemoglobin can carry up to four molecules of oxygen1b,2b. Oxygen uptake Blood is pumped from the right ventricle to the lungs to be oxygenated. In the alveoli, the partial pressure of oxygen is higher than that in the blood and the partial pressure of carbon dioxide in the alveoli is lower than that in the blood. The pressure differences make it possible for oxygen to diffuse from the alveoli to the blood, thus binding to the iron in the hemoglobin. Carbon dioxide on the other hand diffuses from the blood to the lungs. Carrying oxygen, blood is returned to the left atria then to the left ventricle which pumps it to the rest of the body2c. Oxygen release: In the tissues and organs, the cells are undergoing metabolism, continually consuming oxygen and releasing carbon dioxide. This means that the intracellular partial pressure of oxygen is lower than that in the blood and the intracellular partial pressure of carbon dioxide is higher than that in the blood. Again the pressure differences make it possible for oxygen to diffuse from the blood to the cells and carbon dioxide from the cells to the blood, binding again with the iron in the hemoglobin. Therefore, as blood flows around the body, it continually distributes oxygen2c,6. BLOOD SUPPLY TO THE HEART Coronary flow In order to perform its functions, the heart an abundant supply of oxygen and nutrients and therefore needs a dedicated supply of blood. Coronary circulation is that part of the systemic circulation that provides blood supply to the heart. Just as the aorta leaves the left ventricle, it gives of the right and left coronary arteries9. The left coronary artery divides into smaller braches supplying blood to the apex and the posterior side of the heart, the ventricles and part of the anterior interventricular septum, the left atrium and posterior wall of the left ventricle. The right coronary artery supplies the lateral aspect of the right atrium and ventricle, the posterior wall of both ventricles and the SA node9,10. Effect of reduced coronary flow on cardiac function The energy demand of the cardiac muscle is so crucial that an interruption of blood supply to any part of the myocardium can cause necrosis within minutes9. A decrease in coronary flow to levels below normal is called myocardial ischemia. The ischemia can be caused by vascular spasms of the coronary arteries, atherosclerosis or increased activity of the heart beyond levels that the coronary arteries can supply10. Temporary or reversible obstruction of coronary blood flow can cause chest pain known as angina pectoris9. Chronic myocardial ischemia can lead to myocardial infarction where myocardial cells die and are replaced by scar tissue. Reduced coronary flow therefore can affect cardiac function in several ways. If the heart is not able to meet its metabolic demand, it can be understood that it will not be able to pump enough blood to the body. Reduced blood flow to the rest of the body can result in serious physiological and pathological conditions which are beyond the scope of this essay. With the death of some cardiac cells as in the case of chronic ischemia, several other life threatening conditions can arise which affect cardiac function. One of such dangerous conditions is ventricular fibrillation which is an abnormal pulse generation triggered by the damaged myocardial cells. The heart will not be able to pump blood but will just quiver around without any net output. Death can occur within minutes2b,6. Treatment of reduced coronary flow Other immediate effects like ventricular fibrillation caused by reduced coronary flow can be treated by defibrillation. However, the main cause of reduced coronary flow is coronary artery occlusion or restriction and the following treatment options are available: Coronary bypass: This is a surgical technique where the occluded coronary artery is cut and replaced by a new blood vessel, usually a vein taken from somewhere in the patients body2b. Coronary balloon angiography (cardiac catheterization): This is another surgical procedure where a catheter containing a balloon at its tip is passed into the occluded artery. The balloon is enlarged thus stretching the artery and opening it in the process2b. The use vasodilator drugs such as nitroglycerine: These drugs dilate the coronary artery thereby lowering the total peripheral resistance. This reduces the work the heart must do in ejecting blood. This is usually given to people who have already suffered myocardial infarction to reduce the risk of another occurance2b,10. A person at risk of myocardial infarction can be put a low cholesterol, low fat diet to reduce the risk of atherosclerosis and takes aspirin to reduce the risk of blood clot formation. Conclusion The cardiovascular system is one of the most important systems of the body. All the other systems and organs of the body depend on it for supply of oxygen and nutrients and removal of metabolic wastes. The heart acts as a pump to make sure blood is circulated to all parts of the body through pulmonary and systemic circulations9. However, the heart itself needs supply of blood in order to perform its main function of pumping blood and the heart is supplied by the coronary circulation. Reduction in coronary flow means the heart will not be able to meet it metabolic needs and therefore cannot pump enough blood. This can adversely affect normal activity of the body and cause death10.

A muscle fiber (cell) is surrounded by the endomysium. A group of these cells is wrapped by fascicles. Bundles of fascicles are covered by the perimysium and bundles of the perimysium are wrapped by the epimysium to form a muscle. The muscle fibers have contractile properties which enable them to move bony levers in order to produce skeletal movement1. The functional unit of the muscle fiber is the sacomere which consists of most importantly, actin and myosin. The actin and myosin are arranged such that during contraction, they can slide over each other thus shortening the muscle2. Muscles suffer from many diseases, one of which is polymyositis. This is an inflammatory myopathy that affects mainly the muscles of the thorax and those around the torso. It affects all age groups but has been noticed mainly in late childhood and early adulthood. The sypmtomps are nonspecific but results in general muscle weakness and the cause, though believed to be an invasion by the white blood cells, is not very clear10. 2.0 The Structure of Skeletal Muscle. In daily life, structures and arrangements of designs are dictated, to a large extent by the purpose and function for which the design is meant for. Knowing that skeletal muscle is made up mainly of fibrous tissues, the arrangement of these tissues and how they are bound together to maintain a particular shape in order to accomplish different purposes (mainly to generate force and produce movement) may to a large extent, define the structure of the muscle4. At a macro level, the skeletal muscle is composed of bundles of individual muscle fibers, the supporting structure called the basal lamina, and the connective tissue sheaths as shown in figure 1. These connective tissues bind the cells together giving them strength and partly providing mechanical protection2. We can examine these connective tissues and their functions as follows: 2.1 The basal lamina. This is an extracellular matrix that acts as a scaffold on which a cell sits. It has been realized that apart from providing structural support, the basal lamina can orient and constrain cell during the process of regeneartion3. 2.2 The endomysium. This is a fine sheath of connective tissue that surrounds each individual muscle cell. The endomysium consist of loosely interlacing fibers composed mainly of collagen4. 2.3 The perimysium and fascilces. The individual muscle fibers wrapped by the endomysium, are grouped together in what is called fascicles. A layer of fibrous tissue called the perimysium wraps each fascicle4. 2.4 The epimysium. This is the outside layer that finally wraps the whole muscle. It is composed of dense irregular connective tissue4. Figure 1 Source: http://www.web-books.com/eLibrary/Medicine/Physiology/Muscular/muscle_structure.jpg 3.0 The muscle cell Having described how individual muscle cells are organized into a muscle, it is imperative that we look at the structural composition of the cell itself. Just like many other cells in the body are specialized according to their functions, skeletal muscle cells are specialized to produce force and movement5. The skeletal muscle fiber is thus composed of mainly three structural elements:-the myofibrils, the sarcoplasmic reticulum and the mitochondria, each contributing a unique aspect of muscle function. The entire function of the muscle can be attributed to the shifts in proportions of these three structures6. 3.1 The Myofibrills. These are cylindrical specialized sub-units within the muscle fiber. They consist of two types of contractile protein filaments-the thin filaments referred to as actin and the thick filaments referred to as myosin. The two most important parameters of the myofibrils are their diameter which determines its strength and the fiber length which determines it contraction velocity and distance over which the fiber can contract. The myofibril consist of two filaments-actin and myosin6,2. 3.1.1 Actin (thin filament). Actin filaments are responsible for regulation of contraction. The actin filament is formed by a helical arranged of actin monomers which is an ambiguous protein2 (figure 2). Because of the helical nature, a long grove is formed along the filament and the protein troponin is located at intervals along the length of the actin filament. It is troponin which is responsible for turning on contraction2,7. Figure 2.The actin molecule. Source: http://www.ucl.ac.uk/~sjjgsca/Muscleslidingfilament1.gif 3.1.2 The Myosin (thick filament). Myosin filament is about 150nm long. It has a tail and two heads. The tail is formed by two helical shaped fibers that coil around each other. A collection of several of these helical tails together form a myosin filament (figure 3)4b. Figure 3. The myosin molecule. Source: http://webanatomy.net/anatomy/myosin.jpg. 3.2 The sarcoplasmic reticulum (SR). Groups of about 200 thick and thin filaments constitute a myofibril. Each myofibril is thus enclosed in a membrane called the sarcoplasmic reticulum8. The SR membrane stores and releases calcium during muscle contraction and relaxation. The SR can therefore be thought of as the functional unit of the myofibril9. 3.3 The mitochondria. Found within the cell cytoplasm, the mitochondria are responsible for generation of most of the cells energy by the production of adenosine triphosphate (ATP). There are several mitochondria distributed along the length of a myofibril4. 4.0 The mechanism of muscle contraction Muscle contraction can largely be attributed to the structure of actin and myosin, their arrangement within the SR and the interaction between them in order to produce force (Figure 4). This type of arrangement allows the thin actin filaments to slide in and out by the action pull of the myosin heads8b. Figure 4. Actin and myosin arrangement: Source: http://www.exrx.net/Images/ActinMyosin.gif Muscles are composed of a number of actin and myosin filaments arranged in series in a basic unit called the sacomere. The sacomere consists of a thick filament in the meddle and two thin filaments, one overlapping on each side. The heads of the thick filament attach to the thin filament at the overlap and these heads allow movement in only one direction. When activated, each thick filament head rachets repeatedly along the actin, pulling the two actins closer together. Since the actin are attached to the Z line (The distance between two Z lines form the sacomere), ends of the sacomere (Z lines) are pulled in and the sacomere shortens. The sacomeres are arranged in series so that when the muscle fiber contracts, all the sacomeres contract simultaneously transmitting the force to the end of the muscle. The whole process of contraction described above occurs when the muscle is electrically stimulated2b. 5.0 Muscle stimulation. Skeletal muscle cells are stimulated by the motor neurons of the somatic nervous system. The reception of the motor stimulus (action potential) opens the calcium channels allowing calcium which is stored in the SR to be released. The release of calcium causes the release of acetylcholine-Ach (neurotransmitter). The calcium binds to the troponin on the actin filament. Troponin then regulates the tropomyosin which obstructs binding sites for myosin. This allows the tropomyosin to move, unblocking the bonding site. Myosin then binds to the unblocked site on the actin and applies a pull. This will pull the Z bands towards each other thus shortening the sacomere, causing muscle contraction2b. However, as calcium is released, the ATP-dependent calcium pump is activated and it continuously pumps calcium back to the SR to be stored again. This leads to a drop in calcium level within the cytoplasm. When the calcium level is too low, the calcium binding action to troponin is terminated, releasing tropomyosin which again blocks the binding site. This stops the interaction between actin and myosin thus relaxing the muscle2b. 6.0 Muscle Diseases There are a number of muscular diseases and disorders ranging from acquired, familial to congenital. Limiting ourselves to one of the acquired disorders of the muscles, lets look at polymyositis. 6.1 Polymyositis (PM). PM is a type of muscle inflammatory myopathy. Just like the name suggests, this disease causes inflammation of the muscle fiber. Although the causes of the disease are not well understood, it is believed that PM begins when white blood cells, spontaneously invade muscles. This can result in severe muscle weakness. Polymyositis is a persistent disease characterized by periods of increased and reduced or no symptoms. PM affects mainly the muscles of the thorax and is more common in women than men. It is said to affect all age groups although is it commonly noted in early childhood or 20s10. Key pathologic and diagnostic features of the disease. Endomysial inflammation. This is the inflammation of the outer connective tissue that surrounds the muscle fiber. This is done by the white blood cells that leave the blood and enter the tissue, somehow confirming the earlier assertion that the PM begins when white blood cells invade muscles. Invasion of myofibers by autoaggressive lymphocytes. This is when the T lymphocytes begin to attack the intact myofibers. Unlike in muscle dystrophy where inflammation is associated with degenerating myofibers, the invasion of T lymphocytes causes inflammation of health myofibers in PM.This causes inflammation of healthy myofibers. Other diagnostic features that may not be exactly specific to PM include myofiber necrosis, myophagocytosis, myofiber atrophy and fibrosis, a feature of chronic PM10,11. 7.0 Conclusion Human movement is only possible because of the action of muscle contraction. Voluntary contraction of muscle is made possible by the somatic nervous system which sends out an action potential activating the contraction process. The process is accomplished by the sliding of myosin and actin over each other. Many diseases and disorders affect muscles, prominent among them is muscular polymyosis which causes inflammation of the muscles mainly around the torso. Its believed to be caused by the unwanted action of the white blood cells and the symptoms include muscle weakness.

The Preatorian Guard Essay -- History, Emperors of Rome

Introduction Their name alone invokes many vivid images; from heroic men clad in Roman red iron to bloody battlefields, where they stand disciplined and ordered while chaos reigns all around, and even of the quiet corridors of the Emperors’ palace, where a change in power and leadership is only a blade thrust away. These fierce and hardy men formed the iconic symbol of the Ancient Roman Army: the Praetorian Guard. Rigid and unwavering, these soldiers were the bodyguards of the most powerful men in the ancient world: The Emperors of Rome. Formally created in 23 BC by Gaius Julius Caesar Augustus the Praetorian Guard Served as Bodyguards for the Emperors, About nine cohorts of five hundred men each formed the early Praetorian Guard; they were stationed right outside the center of Rome. The Praetorian Guard were recruited primarily from central Italy, unlike most of the Roman Army, the Guards were made up of all Italian citizens and they are referred to as â€Å"the true-born sons of Italy† by Piso the chosen heir of Galba. â€Å"The Praetorians therefore became the symbolic living descendants of the glorious Roman past† (Wasileski 32).The Praetorians were thought to be the Emperors’ symbol of power â€Å"The Praetorians were a visible symbol of that [Emperor’s] force in the Capital† (Wasileski 1). The transition from Bodyguard to Political Power gave the Praetorian Guard a sense of power, especially the Praetorian Prefects Most of the infamous stories surrounding the Praetorian Guards assassinating their emperors are in fact only about a few guards following a very ambitious Praetorian Prefect. Praetorian Prefects usually do not serve with Praetorian’s before taking command. They are mainly administrators for the Guard and most do not have ... ...ki 20). It also should be known that the Praetorian Guard was still a personal bodyguard and on most occasions they served their Emperors faithfully and they actually helped keep the peace and continued to do their duty to the Emperor overall. However with the realization of their political powers the Praetorian Prefects will use the Praetorian Guard to affect what happens behind the palace doors more frequently and more suiting to their own agendas. Those loyal and heroic men of the Guard are slowly being turned into infamous tools used to further corrupt ambitions and disloyal treasons. Though despite all of the bribes and corruption the Guard will always be that awe striking symbol for Roman might, they will always be remembered as the Emperor’s right hand. They will always take their place in the hallowed annals of history as the Emperor’s elite bodyguards.

Free College Admissions Essays: Slacking :: College Admissions Essays

College Admissions: Slacking It's unbelievable how each year, since the beginning of high school, my perfectly laid plans for myself have unavoidably deteriorated. When I entered my freshman year, I had aspirations of being a doctor (something I had wanted to be since I was a child). Now, here I am entering my senior year in high school without any idea of what I want to do. Now seems to be the time to start taking life seriously and making responsible, educated choices. Looking back on it now, I realize that I cannot become the doctor I wanted to be. I have come to realize that, that dream was not only my own, but a dream of my family. My parents often talked of me becoming a doctor and although their enthusiasm continued throughout my childhood and early adolescence, mine slowly diminished; until finally I realized I did not want to become a doctor. I remember how hard it seemed to tell my parents of my decision, I felt as if I was letting them down, but I eventually came to realize that they wanted me to do what made me happy. I am not definite why I changed my mind in regard to being a doctor, I had the grades, the drive, and the willingness to make certain sacrifices, but somewhere I was missing something and I felt that I would not be satisfied in a medical career. So I started thinking about what I wanted to do; I went from teaching to law enforcement, computer programming to astronautics and numerous other professions. Now I come to a crossroad in my life where I must choose what to do with my future, choose what will make me happy. I have always wanted the typical 'American Dream' to have a husband I am in love with, a stable job, loving children, and a house in the suburbs. But now I realize that there are so many other steps I need to take in order to achieve these so-called goals. This includes graduating from high school and college, finding that special someone, and finding that perfect job. I have begun to realize that I have yet to begin my life; everything up until now has been practice, as if I have been in a cage and it is only now that I am beginning to break free and do things for myself.

Analysis of Goodwill International Essays -- Nonprofit Analysis

Goodwill International is a not-for-profit organization whose main objective is to offer job trainings, employment placements, and other community-based projects to individuals with disabilities. The organization also extends its services to veterans who include people who lack the necessary job experience, education, or face challenges in securing employment. The non-profit organization is financed by a chain of retail thrift stores, which also operate as not-for-profit entities in places where they are situated. Goodwill is constituted by a system of 165 community based independent organizations operating in 15 countries, including the United States, Brazil, Venezuela, Uruguay, Panama, and Canada among others. The organization uses the most part of its revenues to provide training, employment, and other relevant support to its dependants who are currently more than 6 million. This paper assesses Goodwill International based on key concepts such as volunteerism, accountabilit y, strategic planning, and fundraising in relation to its mission, vision, and purpose. In addition, the paper suggests several recommendations that could bring various benefits to Goodwill if implemented. Although Goodwill International is successful, it is not efficient and needs to implement additional strategies to improve its efficiency. There are a number of recommendations made in this paper to assist Goodwill International to enhance its efficiency. Some of the strategies include: improvement of its communication strategy, enhancement of its fiscal health, implementation of new marketing strategies, introduction of employee performance measurement techniques, and changing its donation policies to include more items.

Reflections Theory

Reflections theory Introduction In this report I will be comparing two reflective theories, outlining their similarities and differences. I will be choosing the one I believe to be the best in my opinion. This will be the one I will be using in my end of year reflective account. The two reflective theories I will be looking at are, Johns Model of Structured Reflection and Gibbs’s Reflective Cycle. Theories There are two main differences between the two theories. Johns uses a linear structure, with a beginning and an end.However, Gibbs uses a more cyclic structure and has no defined beginning or end. John’s theory is also mainly aimed towards health care and talks about working with patients and their families. Gibbs on the other hand can be aimed more towards students and their experiences. Johns uses the 2 main headings: Looking in and looking out. Under Looking in there are 5 Sub-Headings: Aesthetics, Personal, Ethics, Empirics and Reflexivity. Johns for the most part requires the need to work with a supervisor and as such he calls this a guided reflection.It requires you to write a description of the experience before you begin the reflection, once you have done this it requires you to follow the questions as they come up. One of the advantage of Johns reflective model is that there is a clear Beginning and an end meaning the person looking back on their experience has a clear outline on where to begin and the process used in the reflection. However the issue with the reflexive pattern of knowing is that it will only be relevant for a situation that has been resolved.If your were trying to analyze a situation that’s was ongoing you would have to incorporate parts of another reflective model to help you. With Johns model of structured reflection you would not have to use all the questions within the model, but you could also use the questions a number of times if appropriate. Gibbs Reflective Model is easier to be used by students as it t alks about getting a clear understanding the situations. It uses the six main Headings: Description, Feelings, Evaluation, Analysis, Conclusion and Action Plan.It uses these heading to gain a clear understanding of what went on, what was the experience like for the person, how they interpreted the situation, what they could have done and what they would do again if the situation arose again. Because there is no defined structure and no definite beginning or end, there is the advantage that if the person going through the reflection of their experience and they look back on it they can add more information to each section as and when they think of it, so they can go back or forward to one of the headings and add in the information into the specific field.For example if they feel they need to talk about their feeling first they can do that or if they feel they need to evaluate the situation or talk about what they would do again, and add their input to it, as they can go through the c ycle as many times as they need to get all the information down. Gibbs also talks about what would we do different if the situation arose again. They both put great emphasis on the feelings and the emotions of the person throughout the reflection process. They both talk about what happened and try to make sense of the situation. They both also talk about ConclusionTo conclude the theory that I will be choosing for my reflective practice at the end of year is, Gibbs Reflective Cycle. I have chosen this reflective model for a number of reasons. I believe that Gibbs reflective cycle is more aimed towards Student whereas Johns is aimed more towards health care and talks about working with patients and their families. Gibbs reflective model is also easier to interpret and I believe it to be easier to use to analyze any given situation with the main headings it uses to gain information about the situation the feelings of the person and the experience the person underwent during any given situation.I believe it is easier to follow than Johns model of structured reflection. Gibbs reflective cycle does not require the need of a supervisor to aid the reflection whereas; John’s model talks about have one present to go through the reflection process. I will be using Gibbs Reflective cycle as I feel that it is more relevant to myself and it is clearer to follow and would be easier to use for my reflection process.

The Adaptation of Archaea to Acidity

The adaptation of archaea in acidic condition. How archaea adapt to acidic environment ? Use variety pH homeostatic mechanism that involve restricting proton entry by cytoplasmic membrane and purging of protons and their effect by cytoplasm. pH homeostatic mechanisms The cell membrane is highly impermeable to protons Membrane channel have a reduced pore size. Protein influx inhibited by chemiosmotic gradient Excess proton pumped out of the cell Cytoplasmic buffering helps to maintain the intracellular pH 1.The cell membrane is highly impermeable to protons High impermeable cell membrane to restrict proton influx into the cytoplasm Example : Archaeal-specific structures composed of tetraether lipids . Thermoplasma acidophilum, Ferroplasma acidiphilum, sulfolobus solfataricus. Factor causing low permeability of acidophile membranes. Monolayer composed of unique â€Å"tetraether lipids† in which two hydrophilic heads attached to the same hydrophobic tail through ether bonds †“ more stable, less fluidBulky isoprenoid core. Ether linkage characteristic of these membranes less sensative to acid hydrolysis than ester linkage. 2. Membrane channel have a reduced pore size. Control size of the entrance to the pore and the ion selectivity at the porin entrance. Control influx of proton across the outer membrane 3. Protein influx inhibited by chemiosmotic gradient Inhibit the influx of protons using a chemiosmotic barrier against the proton gradient (higher ? lower)Chemiosmosis : diffusion of hydrogen ion across the biological membrane via transport protein due to a proton gradient that form on the other side of the membrane. 4. Excess proton pumped out of the cell Active proton pumping Remove excess protons from cytoplasm and balance the pH value in cell. Sequences acidophile genomes have proton efflux systems. 5. Cytoplasmic buffering helps to maintain the intracellular pH Intracellular mechanism help to improve the ensuing biological damage.Cytoplasmic buff er molecules that have basic amino acids capable of sequestering protons.

Relationship Between Transformational And Transactional Leadership Skills Education Essay

This paper will measure the relationship between transformational and transactional leading accomplishments in principals of kindergarten through eight class schools. Seven assorted beginnings incorporating diaries and surveies have been critiqued and delineated. The find from these articles is that principals with transactional and transformational qualities lead efficaciously. The ultimate end of a principal is to make a safe acquisition environment where pupils are able to larn to their highest potency. The focal point of this paper is to research class schools runing from kindergarten through eight classs and to supply the reader with ample qualities of an effectual transformational and transactional leader.Problem StatementRecent surveies suggest that kindergarten through 8th grade pupils in the United States are fighting to run into criterions and are falling behind ( Lucas & A ; Valentine, 2002 ) . Educators and principals must be held accountable. Transformational and transac tional leaders obtain accomplishments that will advance pupil success and teacher answerability. Leaderships that usher pedagogues, equals, parents, and pupils within the transactional and transformational attack will ensue in a positive school environment and pupils will work to their highest potency.Purpose StatementThe intent of this research is to supply principals, or leaders with effectual tools for guiding, making, and taking efficient and successful schools. Principals need to hold a clear, concise appreciation on taking efficaciously. This thesis will supply them with accurate surveies that support transactional and transformational leading.Research Questions and AimsTransformational and transactional leading defined Implementing transformational and transactional leading accomplishments for principals Educators efficaciously learning under the counsel of a transformational and transactional leader Promoting pupil success and accomplishment for principals of kindergarten through 8th class schoolsBodyTransformational and Transactional Leadership Skills DefinedCharisma, inspiration, and efficaciously pass oning with subsidiaries are three qualities of transactional and transformational leaders ( Anderson, 2008 ) . Principals that obtain these features will make a respectful resonance with pedagogues, parents, and pupils ( Hood, Poulson, Mason, Walker, & A ; Dixon, 2009 ; Lucas, & A ; Valentine, 2002 ) . Transformational leaders inspire and create positive on the job environments ( Bono & A ; Judge, 1004 ) . Transactional and transformational leaders encourage squad work and concerted acquisition schemes. Educators that are led under the transformational and transactional attack will be able to portion thoughts with other members of the school community. Educators will be advised to detect other schoolroom scenes and learn signifier other instructors ( Chin, 2007 ) . Principals that lead in this attack will make a positive working and learning environment. Students will be able to larn efficaciously and pedagogues will be encouraged to work with and larn from fellow equals. One recent survey explored the transformational leader and concludes that leaders whom hold subsidiaries accountable and continuously evaluate and review in a positive manor will be successful leaders ( Chin, 2007 ) . This type of answerability can be measured though self ratings ( Pounder, 2008 ) . Transformational and transactional approached to leading must be implemented for a successful school environment ( Lucas & A ; Valentine, 2002 ) . Researchers studied teacher studies and focused on five countries dwelling of shared ends, learning coaction, teacher acquisition, teacher certainty, and teacher committedness. The writers hypothesized school principals whom score high in the identified five factors are effectual transformational leaders associating to student success in schools. They intended for pedagogues to finish a study that evaluates their principal ‘s transformational leading manner. These 18 simple principals and their modules were asked to return the study in order for the writer to decently measure the ratings ( Lucas & A ; Valentine, 2002 ) . With the collected information, the writers discovered that increased transformational leading principals were associated with schools that demonstrated enhanced degrees of societal organisations reflective of effectual schools. The survey besides investigated two research questionnaires. The first was questionnaire was from Bass and the 2nd from Avolio. These questionnaires determined that increased transformational principals are associated with schools that show high degrees of societal organisations and pupil success, corroborating the writers ‘ hypothesis ( Lucas & A ; Valentine, 2002 ) .Educators efficaciously learning under the counsel of a transformational and transactional leaderVariable One: Evaluation and Accountability One of import quality of effectual instruction is that pedagogues are able to self evaluate and self examine their instruction schemes ( Pounder, 2008 ) . Prior to school beginning, instructors will be asked by the transactional principal to self measure one lesson per one-fourth of the approaching school twelvemonth. The lesson program will be submitted to the principal. The pedagogue will observe the pros and cons of their lesson. Self rating will advance the pedagogue ‘s ability to guarantee that effectual lessons and activities are taught and implemented in the schoolroom ( Poulson, Mason, Walker, & A ; Dixon, 2009 ; Lucas, & A ; Valentine, 2002 ) . Principals that lead in the transactional and transformational attack can besides promote pedagogues to measure other equals. Educators can larn from one another, portion thoughts, and hand in glove learn under this type of leading. ( Poulson, Mason, Walker, & A ; Dixon, 2009 ) . This environment will ensue in a positive ambiance for parents, instructors, pupils, and staff members. Similar to self rating and equal rating, the transformational and transactional principal will be able to measure and detect the pedagogue. The principal will run into with the instructor prior to the ascertained lesson. The principal will be provided with the pedagogue ‘s lesson program and together they will choose a day of the month for the observation. Following, the principal will detect the lesson. This transformational and transactional leader will inquire the undermentioned inquiries ( Anderson, 2008 ; Lucas, & A ; Valentine, 2002 ) : Did the instructor grasp the pupils ‘ attending? Were the pupils engaged throughout the lesson? Was the stuff presented in a clear, concise manor? Were the demands of each type of scholar met in the lesson? What were the pupils making throughout the lesson? Did the instructor cheque for understanding and inquire follow-up inquiries? How was the lesson concluded? These are seven inquiries that the principal will observe throughout the lesson. Finally, the principal and instructor will hold a station conference sing the observation. At this conference, the principal will be able to supply the pedagogue with notes and remarks refering to the ascertained lesson. The principal will be able to discourse strengths and failings and offer tools for betterment ( Bono & A ; Judge, 2004. Variable Two: Professional Growth Transformational and transactional leaders must promote members to continually enhance professional growing. Continuous larning for pedagogues will advance effectual pedagogues. As a transformational and transactional principal, chances for growing and betterment must be available for pedagogues. Workshops, seminars, and meeting are indispensable for effectual instruction and for teacher answerability ( Bono & A ; Judge, 2004 ) .Promoting pupil success and accomplishmentStudents will stand out under a transformational and transactional leader ( Chin, 2007 ) . Students respond positively to leaders that are magnetic, rational, and originative. Students are able to set up a respectful resonance with the disposal and school personal ( Chin, 2007 ) . Principals whom set up the foundation of transformational and transactional leading accomplishments will advance pupil success and accomplishment. Datas from 1,762 pedagogues and 9,941 pupils in one big school territory were obtained to research the effects of transformational leading patterns on selected organisation conditions and pupil battle within the schools. The consequences confirmed that there were strong important effects of such transformational and transactional leading on pupil success rate. This partciular article was qualitative and provided voluminous sum of information associating to the field of transformational leading and its benefit in schools ( Leithwood, 2000 ) . Transformational and transactional leaders obtain qualities that are animating and successful. Principals who lead in this attack will make a safe acquisition environment where pupils are able to larn to their highest potency ( Hood, Poulson, Mason, Walker, & A ; Dixon, 2009 ) . Teacher answerability and public presentation is the 2nd measure within the transformational and transactional attack ( Chin, ( 2007 ) . Teachers must be able to self evaluate, evaluate equals, and take part in principal-teacher rating. Educators must go on to turn professional and go on their instruction.

The BARS also provides the business understanding that should e incorporated into message implementation guides and other user documentation as well as supporting re-use of artifacts within the standards development process. 3 Audience The main audiences for this document are the potential authors of individual Bars. These are primarily the ANNUNCIATE business and IT experts who are responsible for specifying the business requirements for e-business or e-government solutions in a specific domain and for progressing the development of solutions as relevant standards.Authors may include other standards bodies or users and developers in developed or developing economies. Reference Documents Knowledge and application of the following standards is crucial to the development of quality business requirements specifications. Other key references are shown in the appropriate part of the document. UN/CAVEAT. Techniques and Methodologies Group (TM). ASPECT'S Modeling Methodology (MUM): MUM Meta Model – Core Module. (Candidate for 2. 0). 2009-01-30. Methodology (MUM): MUM Meta Model – Foundation Module. Candidate for 2. 0). Formal definitions of many of the technical terms used in this BARS specification may be found in the above references but for convenience some key definitions are included in Appendix loft this document. 5 purpose of BARS 2. 0 A BARS is designed to capture the requirements that a business, government or sector has for an e-commerce solution in a particular area of business (I. E. Domain) and to achieve it in such a way that it provides a basis for a subsequent standards development process within ANNUNCIATE.Version 2 of the BARS documentation template requires that the business requirements are first specified in business terms and that these requirements are then expressed formally as ML diagrams or worksheets that aid standardization and provide IT practitioners with the required retracts from which to develop formal specifications. By facilitating consistent documentation of business collaborations between participants, the BARS 2. 0 template supports the standardization and harmonistic of business processes and encourages re-use of the resulting artifacts in part or as a whole.This consistency, achieved through the systematic specification of requirements in the BARS, is vital if resulting e-business systems are to be interoperable. A clear specification of business requirements enables traceability between requirements and supporting the quality assurance process. As the BARS provides the description of the equines processes and identifies the business data needed to support those processes, it can provide the necessary business understanding to enable successful data harmonistic.It also provides the business understanding that must be incorporated when developing message implementation guides and other user documentation. The use of a modeling tool that is designed or configured to support Version 2. 0 of the MUM will enable the majority of the content of a BARS to be generated automatically. This document may also be considered as a resource to support capacity building in developed or developing economies. 1 Overview of BARS Development Process A BARS MUST start with a clear specification of the scope of the project and where this project fits into a global context of business operations and MAY refer to a MUM model of the business domain. The Scope MUST be specified in terms of the Business Processes that are involved and the Business Entities about which information is to be exchanged by the participants who are involved directly in the Information Exchanges that support the related business process.It MUST also indicate stakeholders who have an interest in the processes, or may participate in elated processes, and whenever appropriate, what is out of scope of this particular project. The process and information flows that constitute the business process, the business rules that gove rn the exchanges and the details of the information that is to be exchanged during these processes, SHOULD then be elaborated.The requirements MUST first be specified in business terms and then expressed in formalized terms. The business requirements MUST be presented as a numbered list so as to facilitate a check to be made that all requirements have been met in the eventual e-commerce solutions proposed. As the process of completing a BARS progresses, new requirements may be recognized and added to the list. The resulting BARS will include text, templates (worksheets) and diagrams, and may refer to a MUM model of the domain.To help with future re-usability, interoperability and to provide a degree of standardization in the developing a BARS, an initial set of preferred terms is provided in Annex 2. To minimize the work in creating a new BARS, improve harmonistic and encourage risibility, where ever possible, any relevant existing Bars artifacts or MUM models SHOULD be used as a ba sis for producing the ewe requirements. A high level BARS MAY be used to define the context and scope of a domain that is refined by a cascade of more specific Bars. . 2 BARS Business Requirements 5. 2. 1 Scope of Project The Scope of the project MUST be identified in terms of the Business Processes to be covered – the key types of information that are to be exchanged in the processes and the types of participants that are involved directly or indirectly in providing or using the information exchanged. The place of this project within the wider business domain SHOULD be identified. For example projects in the International SupplyChain, this SHOULD be positioned with respect to the international supply chain be made to industry or sector models and to the Business Area/Process Area classification specified in the Common Business Process catalogue. The Context categories , as specified in ACTS, SHOULD be used to help specify or limit the scope of the project. 5. 2. 2 Requiremen ts List As they are discovered, the business requirements MUST be added to a numbered list .This list will cover: The business transactions between participants, the participant who initiates the activity, the participant who responds and the business conditions that govern the initiation and responses. Other business rules governing the Information Exchanges. The key classes of information (Business Entities), the detailed data (attributes) about these Entities that are to be exchanged, and the relation between the Entities. 5. 2. 3 Definitions The names and definitions of each of the business terms and data items used MUST be listed and SHOULD be added as they are discovered in the process of completing the BARS. . 2. 4 MUM representation of Business Requirements The business requirements MUST be formalized as appropriate ML artifacts, (Use Case Diagrams, Activity Diagrams, Class Diagrams and Business Entity Life Cycle Diagrams) or worksheets, by following the Insufficient Modelin g Methodology (MUM). 5. 2. 5 The UN/CAVEAT Modeling Methodology MUM An outline description of the MUM process is given below and examples of artifacts that should form part of the BARS are shown in section 7.The MUM consists of three main views: The Business Requirements View enables the Business Information and Business Processes described in the first part of the BARS to be more formally described. The Business Choreography View shows how the Business Processes may e created from a choreographed set of Business Transactions and the information exchanged in each transaction identified as Information Envelopes. The Business Information View identifies the content of these information envelopes based on the specific data and syntax standards and is the substance of the related RSI.Figure 1 – MUM Outline MUM Business Requirements View This presents the view of the domain, the business processes, the participants and the Business Entities involved. They are detailed in the Busin ess Domain View, Business Partner View and Business Entity View. The Business Domain View This view identifies the scope of the domain in terms of the processes it covers. The Business Area [Process area classification may be used to classify the business processes that make up the domain. Each business process is represented by an Activity diagram, Use Case Diagram and Business Process Worksheet .These document the Business Partner Types that are engaged in the information governing the initiation of each Information Exchange. The state of the Business Entity resulting from each information exchange is shown in the activity diagram. Business Partner View The business partner view captures a list of business partners and stakeholders in the domain under consideration as well as the relationships between them. Business Entity View The range of states that a Business Entity may assume and the order in which they may occur as a result of the various information exchanges are documented in a Business Entity Life Cycle diagram.This View MAY also contain Conceptual models that present a business view of the Information and the relationships between the Classes identified. The Conceptual Model is assembled from the list of business requirements and expressed through the use of â€Å"class† diagrams. These describe the necessary classes of information, the relationship between the different classes and the required attributes that are to be found within each class.Each of these pieces of information should be fully described in the business definition section. It is important to stress that the class diagram for a Business Entity should reflect the information requirements expressed in business terms. Business Choreography View This shows how the Business Processes identified in the Business Requirements View may be represented as one or more Business Transactions and the necessary hieroglyph to enable the full functionality of each Business Process to be achie ved.It consists of the Business Transaction View, Business Collaboration View and Business Realization View Business Transaction View The business transactions between each pair of data exchange participants that are part of the full Business Process are identified and described in a Transaction Worksheet and illustrated as Use Case diagrams . Six standard transaction patterns are identified within the JIM. Two of these represent participants sending and receiving information (Information distribution, Notification) and four represent artisans sending and responding (Query Response, Request Response, Request Confirm, Commercial Transaction).Each transaction is further detailed in terms of: the name of the Information Envelopes sent or received the Authorized roles exercised by the sender and receiver the Activities that action the sending or receiving of the Information Envelope the conditions that cause the transaction to start or that exist as a result of the exchanges . Business Collaboration View The sequence or order in which the set of business transactions that make up the lull business process is specified using a Use Case Diagram and an Activity diagram in the MUM Business Collaboration View.
