Anwar Sadat Essay

In your view, how have rhetorical techniques been used to reveal memorable ideas in the speeches set for study? Support your view with detailed reference to at least TWO of the speeches set for study. Great speeches combine rhetorical techniques and structuring to reveal and emphasise their key themes and memorable ideas. This is evident in Anwar Sadat’s â€Å"Statement to the Israeli Knesset all of which present ideas memorable in both their original contexts and to contemporary audiences.†, Paul Keating’s â€Å"Funeral Service of the Unknown Australian Soldier† and Sir William Deane’s â€Å"On the occasion of an ecumenical service for the victims of the canyoning tragedy†, One of Sadat’s most memorable themes is the value of â€Å"permanent peace based on justice†. Sadat employs a range of rhetorical devices such as emotive language, repetition, enumeration, imagery and juxtaposition to ensure his audience is convinced of the value of â€Å"permanent peace based on justice† and remembers the idea. Words such as â€Å"annihilate†, â€Å"bereavement† and â€Å"rejection† are used to force his audience to experience how it feels to live without â€Å"permanent peace based on justice†. The repetition of the phrase emphasizes that this idea is one of his key concepts, and also allows the phrase to be brought up again in the audiences mind allowing the concept to ‘sink in’. Sadat also uses accumulation, structuring his arguments as â€Å"the first fact†, â€Å"the fifth fact† etc, and later, when stating his conditions for peace he uses â€Å"first, second, third†. This technique allows his audience to better follow his train of thought and clearly understand how he has come to these conclusions and making his argument seem more logical and correct. Also, by stating his arguments as a â€Å"fact† he gives them more authority. Lastly, Sadat uses imagery to portray two possible futures. One is of â€Å"the ruins of what mankind has built and the remains of the victims of mankind†; the other is of â€Å"a smile on the face of every child born on our land†. By juxtaposing such extreme vision Sadat forces his audience to agree with his pint by appealing to a common goal of a better future. Sadat ensures his audience remembers the idea of â€Å"permanent peace based on justice† by employing a number of rhetorical devices to ensure they both understand and agree with the idea.

“Crow Lake” and “Students” by Tom Wayman Essay

In the two tests â€Å"Crow Lake† and â€Å"Students† by Tom Wayman both show the students and their teachers, but the teachers have not the same ways to teach them. In the two tests there are examples of person vs. person conflict as well as person vs. society conflict. In â€Å"students† and â€Å"Crow Lake† both speakers experience person vs. person conflict in their lives. In the story â€Å"Crow Lake† the narrator is in conflict with himself as well as his teacher in his life. In the test the narrator say, â€Å"My job—assistant professor, invertebrate ecology—has a number of components: carrying out research, analyzing and writing up my findings, writing up my findings, writing papers for publication, giving papers at conferences, supervising graduate students, teaching undergraduates, plus a ridiculous amount of administration.† There is also person vs. person conflict in the poem,† The freshman class first printout s showed birthdatehs so recent.† In the first example, the narrator Mary Lawson is in conflict with his teacher because his teacher teaches him, but their age has many years, even though they have many questions for this, but his teacher’s lesson did not any so boring, it’s so interesting about his teacher’s lessons. He liked his teacher’s lesson. In the second example, the narrator is in the conflict with his teacher, this text also between the teacher and students. As we can see, from these two texts both speakers experience person vs. person conflict in their lives. There is also person vs. society conflict in both â€Å"Crow Lake† and â€Å"Students†. For example in â€Å"Crow Lake† it says, â€Å"Teaching I don’t enjoy at all.† As well in â€Å"Students† it says, â€Å"Wayman observed many clung to the vaccination theory of education, he remembered: once you have had a subject you are immune and never have to consider it again.† The speaker in â€Å"Crow Lake† is the student don’t like his teacher’s teaching way. He thought it was so boring. In the second text â€Å"Students† the speaker is liked his teacher because his teacher has interesting way to teach students. As we can see, both tests reveal the conflict that the speaker undergo when dealing with independence in their new lives through this they both experience person vs. society conflict as they come to grips with the change. In both texts â€Å"Crow Lake† and â€Å"Students† speakers use their teachers to compare, one  teacher’s lesson is so interesting, the other teacher’s lesson is so boring, although their teachers ages would older than them but their class had difference way, and make students had different feeling to listen the lessons. As we can see from these two example, a difficult situation can into a person victory if you continually believe in yourself.

Themes in Rita Hayworth and Shawshank Redemption Essay

Themes in Rita Hayworth and Shawshank Redemption - Essay Example One major theme that unfolds in this book is about the pain and burden of imprisonment and isolation. In this novel, Stephen King has mainly centered the plot on prison life, and inmates at Shawshank Prison. The prisoners in this prison are locked up. This therefore, could be either literally or metaphorically. Stephen King shows the aspect of isolation through the way he has portrayed the prison setting. The prison is enclosed with walls, showing that the inmates were confined inside the prison, thus, were isolated, and denied freedom like that in the life outside the prison walls. The recreation yard in the prison is also enclosed, as well as the cells, where each prisoner lived (King Web). The prison environment in this novel, thus, represents a different world, where the inmates have been forced into after being removed from the free world. They therefore, are confined in the prison, with no opportunity of going back to the outside world, unless their term is over. The lack of fr eedom and alienation from the mainstream society is disheartening to most prisoners, and this has detrimental psychological effects on the prisoners. The pain of imprisonment in this book is evident in the lives of the prisoners. These are faced with multiple challenges in the prison, and therefore, these leave them with endless pain, both physically and psychologically. The prisoners by virtue of being in prison, have to encounter violent and mean people and gangs among themselves, who torture them, both physically and psychologically. The â€Å"sisters,† which is a gang in the prison tortures other inmates by abusing them sexually. On the other hand, both the experience of isolation and imprisonment make most of the prisoners believe that they are incompetent in the outside world. Experiences in the prison have derailed the inmates psychologically, and taken away their confidence and self-esteem. Although some prisoners such as Elwood Blatch want to appear like strong and hardened, deep within, these fear if they will ever fit in life outside prison, and if they will adapt to that life after serving their jail term. Red is also shown as being afraid of coping with freedom in the outside world (King Web). Additionally, Stephen King in this novel developed the theme of hope and its power. Through the different events in this book, one realizes that the author attempts to show the audience that hope is powerful. The inmates at Shawshank have every reason to give up hope, but these have not lost hope. Therefore, it is the hope that they uphold, which is responsible for their continued living and survival. Even though the inmates are faced with the burdens that come with imprisonment and isolation, these have not given up life, nor attempted to take away their life. For instance, Andy comes out as a determined person, who fights to maintain his sense of self-worth and therefore, this virtue is sufficient for him to keep at bay any extreme sense of anger and frustration, which would result from the isolation and confinement he faces in the prison. He serves as the model of an ideal man to other prisoners , and also a epitome of hope, as characterized by his spirit, which never loses hope. Hope is also portrayed when Andy progressively tunnels the concrete wall of his cell, and finally crawls out of his cell into freedom. While outside prison, Andy writes a letter to Red, and reminds him that, â€Å"

Identify the Japanese tourism's promotional strategies Essay

Identify the Japanese tourism's promotional strategies - Essay Example Other than the government, Japan Tourism Agency, JTA has been instrumental in promoting tourism in the country. The Japan National Tourism Organization, JNTO, a government’s independent institution runs tourist information centers and a website that give information on transportation, accommodation and tourist destinations. Private sector players also collaborate with the government in various ways to boost tourism in the country. Promotional strategies According to JTA’s commissioner, Hompo (3), Japanese strategies to attract tourists from across the globe have been based on three pillars. The overseas promotion encompasses establishing the Japan brand by promoting it as a premium destination based on its diversity. The second pillar involves enhancing the hospitality and accommodation facilities in the country with the aim of satisfying its foreign tourists. The government in this regard ensures effectiveness in the transport system and addresses visa related regulati ons, guide signs and immigration control. The third strategy involves attraction of more international conferences, having been ranked fifth and eighteenth in 2007 and 2006 respectively in this regard. According to the Japan Tourism Agency, JTA 1,000 journalists have been invited to reassure the world of the viability of the country as a viable tourism destination. There have been massive media campaigns and advertisements promoting the country as a tourist destination. Movies have also been produced to promote the culture of the Japanese. The government urged hotel owners to upgrade their facilities, the quality of the tour guides it employed and make proper arrangements for its visitors when visiting critical attraction sites. Indeed, these strategies have been successful with McCurry noting that by August 2011, the number of international visitors visiting the country had rose to 547,000 from 296,000 by the end of the year 2010. Target market The promotional strategies employed b y the government of Japan and relevant tourism agencies and partners aim at attracting foreign tourists across the globe. The Japan Tourism Agency aims at attracting over 20 million tourists from across the globe by the year 2020 (Hompo 3). But Ochterbeck (5) notes that these promotions mostly target visitors from great western powers to prove to them the civilization of the country. The priority markets for Japan according to the Commissioner of the JTA include the United States of America, United Kingdom, Australia, Canada, China, France, Hong Kong, Singapore, Germany, Thailand, Taiwan, Thailand and South Korea. Tourist attractions According to the JNTO, the tourist destinations that the government and relevant agencies promote in Japan cluster around Tokyo, the capital city as reported by Schoenberger. This makes the tourism circuit of visitors convenient. These destinations encompass both the traditional and modern sites. Shinjuku, a skyscraper district offers shopping and night life opportunities. The film ‘Lost in Translation’ made Park Hyatt popular providing a penthouse for drinking and having a superb view of the city. Shibuya and Harajuku districts provide tourists with the opportunity to learn Japan’s teen culture. The former capital city Kyoto provides architectural beauty and

Factors Influencing Internationalization and Entrepreneurial Growth of Research Paper

Factors Influencing Internationalization and Entrepreneurial Growth of Family-Owned Businesses - Research Paper Example firms; Generational Involvement is associated with the level of Entrepreneurial indication in family firms; and, Entrepreneurial Orientation is positively related to the internationalization of family firms. Internationalization is the â€Å"process by which firms both increase their awareness of the direct and indirect influence of international transactions on their future, and establish and conduct transactions with firms in other countries† (Koh, 2010, p.22). As 80% of businesses in US are family owned, it is responsible for 60% of employment. Although a lot of these firms are small in size, still they represent around one-third of Fortune 500 Companies and around thirty five percent of the S&P 500 Industrials. (Blodgett et al, 2012) In most companies around the globe, internationalization is an important challenge which they need to address to make sure they remain competitive in today’s Global Economy. An entry into foreign soil is marked with uncertainty which may require breaking away from traditional and long used manufacturing processes, acquiring new channel partners and exploring avenues for funding. However, internationalization can be more even more challengi ng in family owned businesses, because the entry into foreign markets may require structural changes within the organization and most of these firms are extremely unwilling to lose family control. (Casillas et al, 2013). While family businesses aim for expansion, with exploring new markets, they are faced with the opposite force which is stability in their home market, which is relatively low-risk. (Casillas et al, 2013). Studies that have researched into the want of internationalization of family firms reveal an inclination toward family firms wanting to operate in the traditional markets and seem reluctant to venture into foreign territory. (Koh, 2010). This is not to say that NO family firms have surmounted this challenge, quite a few family firms have ventured into international markets and

Article Review(Mirror Molecules) Essay Example | Topics and Well Written Essays - 1250 words

Article Review(Mirror Molecules) - Essay Example L from its name L-amino acids is actually a derivative of ‘laevus’ which means left in Latin while D in D-amino acids is from ‘dexter’ which means right in Latin (Everts, par.5). This substance had only been of significant regard in bacteria. The D-amino acid is considered to be the mirror image of L-amino acid and their mismatch made scientists conclude it was an irrelevant component until recently. There are two theories explaining the prevalence of left-hand amino acids over their right-handed counterparts. The first is based on the argument that it was simply providence that the chemical entities that developed first utilized L-amino acids instead of D-amino acids. Robert Hazen, a geophysicist and an origins-of-life authority from George Mason University, suggests that they were â€Å"grandfathered in† and, thus, initiated the partiality (ibid). ... This indicates the catapulting of left-handed amino acids as the prevailing variation simply by derivation and the consequent years of adherence to this belief. The significant challenging of this rule started in the 1990s when it was found that right-handed amino acids actually play a vital role in the human brain as transmitters. Then by 2002, the discovery of platypus poison with right-handed amino acids was discovered by Philip Kuchel. The year of 2009 was also a pivotal point in the new discovery as â€Å"researchers at Harvard and the Howard Hughes Medical Institute reported that several D-amino acids performed new and unexpected functions in bacterial cell walls† (ibid, par.7). Furthermore, D-amino acids have seen imperative advances in understanding their role in human beings. To illustrate, D-aspartate is an important component in the development of the brain while D-serine combines with L-amino acid glutamate to produce synaptic plasticity which is an element of deve loping memories. The level of right-handed amino acids also has a correlation in certain disorders as researchers have found out. Too little D-serine can be attributed to schizophrenia whereas too much of it can be threatening with a stroke for patients. As a result, studies have been conducted by pharmaceutical companies to address these issues in the hope of developing new cures for these ailments. An important factor in these studies is the benchmark proposition that the body through the brain cells does not actually build D-serine out of nothing, but it creates an enzyme that turns the L-amino acid into the kind of D-amino acid that it needs. Another important use of D-amino acids that

American Government - Research Paper Example ticle handling the roles of the house and the senate, the second article providing for the powers and responsibilities of the president, the vice president and the departments, while the third article caters for the duties and authorities of the federal and the supreme courts. The system of checking the powers is enhanced through having one arm of the government limit the powers of the other. The system of checks and balances can be demonstrated by the nature of relationships between these arms of the government. The executive is authorized to constitute the judiciary through having the president appoint judges. The legislature on the other hand is mandated to approve or disapprove the appointments made by the president. This way, there is a participation of each arm of the government in such decision making, ensuring that no arm exercises excessive powers over the others (Kilman and Costello, 56). The other nature of a relationship is that while the legislature, through the congress passes a law, the executive, through the president can veto such a law (Kilman and Costello, 58). Further, the judiciary can rule on the unconstitutionality of a law passed by the legislature, but the legislature can avert this through initiating the amendment of the constitution to suit such laws, if deemed necessary for the state. Thus, the separation of powers ensures that each arm is acc ountable to the others and by extension the whole republic (Kilman and Costello, 79). The process of passing a bill into a law includes the introduction of such a bill by the congress. The bill can either emanate from the senate or the house of representative, with the person introducing it becoming the sponsor (Kilman and Costello, 107). The introduced bill is then passed on to a selected committee of the senate or the house, depending on the nature and the rules of the process, for consideration. From here it can be passed on to subcommittees for further review. The next stage after the

How Nonprofit Volunteerism Has Changed Over the Years Research Paper

How Nonprofit Volunteerism Has Changed Over the Years - Research Paper Example The researcher states that Martin Luther King, Jr. said, â€Å"Lifes most persistent and urgent question is: ‘What are you doing for others?’† A general definition of volunteerism or volunteer is a person who voluntarily undertakes or expresses a willingness to undertake a service or one who renders a service or takes part in a transaction while having no legal concern or interest. In a way, volunteerism can be looked upon as servant leadership.   According to author Robert K. Greenleaf, the servant-leader is the servant first.   Volunteerism begins with the natural feeling that one wants to serve and is also able to do so.   Then conscious brings one to aspire to lead.   The best test for becoming a servant leader is to ask if those served to grow as persons:   do they, while being served, become healthier, wiser, freer, more autonomous, and more likely themselves to become servants?   Also, it is essential to assess what is the effect on the least pr ivileged in society. It is important to ask if the volunteer act will benefit the disadvantages section, or, at least, not further deprived them. Volunteers are essential components of most nonprofit programs as they provide services to clientele who might not otherwise be served. As such, it can be stated that volunteerism is an important service that enables the non-profit organizations to manage their resources and deliver on their goals. As with any movement, volunteerism has undergone significant changes over the years. This study would trace the changes in the volunteering trends in the US and Canada and highlight the various aspects that are responsible for the changing trends.

Professional Development Article - Essay Example udit, this externally-driven auditing system looks at total enterprise value related to the sales volumes of high-profiting pharmaceutical companies and measures their process and product innovations based on how the auditing committee believes each firm should be molding their corporate strategies. Contained in the article are many pharmaceutical companies and their profitability achieved for 2007-2008, their innovation focus, accounting, and how each firm has positioned itself for growth or loss in the face of how each firm chooses to market its products or its research and development efforts. The fundamental purpose of the Pharma Industry Audit is to ask the question, â€Å"Do you create shareholder value (with your strategies and tactics) or do you destroy it?† (Trombetta, 55). The Pharma Industry audit is much more unique than other well-known, independent auditing firms as it deals with much more than simple accounting issues and financial numbers. The critical issue in this article is that many companies are not addressing the macroeconomic factors that cause potential problems for producing shareholder value, therefore they are using improper business strategy and require the need of external auditing to help them see the larger picture in terms of strategic philosophy. Some of these companies, essentially, fail to view how their markets perceive their performance and dismiss these macroeconomic factors in favor of their own business strategy, which can strip shareholders of return on investment. Critical Factor #1 – The current global recession tends to cloud long-term business strategy when pharmaceutical companies either hold onto their existing business strategies or fail to generate better strategic concepts to improve shareholder value. These are the macroeconomic factors that strongly influence whether pharmaceutical companies are maximizing their market presence either through failure to diversify their holdings or improve their research and

Classical influences in federalist papers-Madison Essay Example for Free

Classical influences in federalist papers-Madison Essay James Madison was the fourth President of the United States and was honored with the title of ‘Father of the American Constitution. ’ Madison is the epitome of intellectual forces, which came together in American politics by the end of the eighteenth century. Bernard Bailyn has hypothesized that the classics in colonial America was ‘illustrative, not determinative of thought. ’ To defy this notion and explain Madison’s ability to perform the role of an architect of a system that successfully integrated political and philosophical views, an assessment of Madison’s life and education will be important. A complex synthesis of classical, modern, philosophical, and rational thought has been revealed by the foundation of the American Republic, as well as, the impact of classical antiquity that was considered thoughtfully. In this regard, a combined political wisdom of thousands of years of human experience was reflected by the implementation of the abovementioned complex synthesis for the formation of a system of government. Simplistic theories of interpretation have been defied by a degree of reflection and contemplation that completed that republican government, which is accounted as one of the most purposefully design by the history of mankind. In two years, after the completion of his first year’s exams, the degree was finished by the Madison in English, Greek, mathematics, and Latin. During this time, Reverend John Witherspoon considered Madison as one of his favorite students, and it was an honor as the Reverend was the president of the college. Employing a syllabus that was classical and Christian Witherspoon taught Madison moral philosophies which greatly affected him for the rest of his life. Tangible manifestation in the Federalist Papers was found by the ability of Madison regarding the classical, as well as, modern political philosophy, which was often referred as quasi-Calvinist cognizance. Wherein the plan for a fractured government was described and advocated by Madison. In addition, any individual person or entity sought precluding of usurpation of the power of governance. This theological system of belief also reveals itself in an existing political philosophy. As per the political thinking of the Calvinist, the grace of God is responsible for all the authority. In this regard, due rights are received by both authority and liberty, when the relation between the citizens and rulers is standardized unbridled authority on the part of rulers lead to despotism, autocracy, and tyranny; unbridled liberty on the part of citizens generates into license, revolution, and anarchy. License, anarchy, and revolution have been generated by the unbridled liberty on the part of the citizens. Stewards from the God are found in the rulers, as proper constitution is formed in the government according to the principles of Calvinism. For God’s sake, the highest motives are considered for the obeying of the rulers by the citizens. An example for the understanding of development of the political, classical, and philosophical amalgamation for the debates that were performed during the formation of the American Constitution was presented by a strong proponent of the classics, Calvinist, and the Scottish Enlightenment Witherspoon. The diverse approach of Witherspoon to education provides an important explanation for understanding Madison’s talent of successfully merging classical and modern political theory into a feasible plan for a secure democratic state. In other words, an extensive intellectual focus was maintained by Witherspoon, by which, discordant philosophical, as well as, theological concepts were blended into an educational program effectively and coherently. When Madison came into politics his instant tasks were clear, first he wanted to put up a proposal for a democratic republican government acceptable to the representative body at the Constitutional Convention, and second, to assure the ratification of the proposed Constitution. From an extensive view point, Madison wanted to produce a classic dissertation on the American system of government, which would enlighten future generations about democratic republicanism. Madison was able to attain both of these goals through one channel and that was The Federalist Papers. This information helps in understanding how extensive knowledge of the classics was acknowledged by Madison and the other two authors. In Federalist no. 14 Madison presents a question, which can function as a good outline of his approach concerning the issue of the significance of the classics to the American people: It has been the glory of American people, as a blind veneration for antiquity, custom, knowledge, experience’s lessons, and objections of their senses has not been suffered by them, as the opinions of former times, as well as, other nations have been paid with a decent regard by these people. The Federalist has considered this thinking approach an obvious thing, since ancients have been referenced frequently by Madison, and their strengths and weaknesses have been borne in mind. When Thomas Jefferson sent the published texts of Polybius from France, the issues of the proposed government were considered by Madison, while positive and negative examples were considered and utilized from the ancient sources by him. Therefore Madison opposes the objections of people who mention the example of Ancient Greece as a sign of un-workability of a permanent republic. He argues that Greece was a democratic system that was often confused with a republic; Madison distinguishes between the two by mentioning that a democracy requires the people to be in assembly in order to carry out the business of the state, whereas a republic requires only the assembly of legislative body to work effectively. Hence he includes both democratic and republican doctrines in his government blueprint. The importance of the classics in the American Republic origin was demonstrated by the evaluation of specific sections comprising of papers of the Federalist, and specifically, the Madison. In addition, classical antiquity’s major references were also included in these sections as mentioned before, Madison frequently opted for classical tradition method to convey his political message, yet Madison often referred to antiquity as a negative prototype for a political culture. One area in which Montesquieu’s political philosophy complements Madison’s tactic is the issue of religion. After historical bigotry of the religion was criticized, and trade was meddled with it, it was commented by him that when the established religion satisfied the state, the establishment of another religion is not allowed. In this regard, establishment of any state religion was banned by the framers of the Constitution. Few smart and wise individuals should be communicated with the important political truths for their wise implementation, which was provided by the writings of the political philosopher, as the relationship between the political community and philosophy was considered as volatile. At the same time, harmful truths were concealed from these individuals by these writings as well. This concept was well aware by the student of Montesquieu, Madison. In the result, the classical and modern political philosophy was concealed by the furthering of his project. In this sense, the role of a crucial link in the chain of thoughts of the Romans and Greeks was played by the Madison, who was served by the Montesquieu. Classics are where Madison’s popular audience was at a majority and this is one fact that he used to his benefit in writing The Federalist Papers. In addition, major references to classical antiquity were contained in six out of eighty-five of the Federalist Papers. Passing references and explicit references regarding the specific indebtedness with a clear sign were contained in the twenty-three Federalist Papers. If these facts are considered, the link between classical antiquity and the origins of the American Republic appears to ignore a serious question. Mark Diamond states that the most immediate kind of political work was the Federalist, which was a piece of campaign propaganda. In addition, a view to the permanence of its argument was also provided to thoughtful men. The widest electorate was at once addressed by it, but able and educated men were also considered, by whom, the fate of the Constitution could be determined. Short-term objective was accomplished by the Federalist, in which, public opinion had to be influence with the relation of political system of the United States. Federalist As mentioned before, the people of New York were persuaded by the publishing of the Federalist for the ratification of the Constitution. It also made an attempt to elucidate different provisions of the Constitution and to enlighten the people by giving reasons, as to why other provisions like bill of rights had been excluded. It was argued by the Publius that an exceptional opportunity of reason and choice had by the Americans for the creation of own type of government. In contrast, earlier constitutions were determined by the chance of force. Publius argued that the Constitution shaped a republican style of government which was effective and sound in nature, but yet was controlled by checks and balances.

Cell Migration And Cell Cytoskeleton Biology Essay

Cell Migration And Cell Cytoskeleton Biology Essay The cytoskeleton of a cell plays a vital role in controlling the movements of the cell. 3 types of fibres form this structure; microtubules, microfilaments and intermediate filaments. Microtubules are large hollow fibres, microfilaments are the smallest at only 6nm in diameter (1) and intermediate filaments are in between. Microtubules are formed from the subunits ÃŽ ± tubulin and ÃŽ ² tubulin, which form dimers. Each tubulin dimer contains 1 ÃŽ ± tubulin subunit and 1 ÃŽ ² tubulin subunit. These then polymerise to form long protofilaments, which join together into sheets. Once a sheet of 13 protofilaments has been formed, they then fold over to produce a hollow microtubule, which continues to elongate from the +ve end where only ÃŽ ² tubulin subunits are showing. Microfilaments are made of a protein subunit called actin. There are two types; G actin and F actin. G actin is turned in to F actin by the hydrolysis of ATP, forming a fibrous filament. The actin filament continues to elongate from the -ve barbed end. There are several types of Intermediate filaments, each made of different proteins depending on the function of the cell in which they are contained. Type I Keratins acidic and Type II Keratins basic are found in epithelial cells and in the hair and nails. Nuclear lamins are found in the nuclear lamina and type III vimentin/desmin/peripherin are found in muscle cells, some neurones and stem cells (2). The monomers form dimers by coiling. Tetramers are then formed from dimers arranged in staggered formation with opposite domains together. These then arrange together forming strong coiled filaments. Many cells move by crawling over surfaces (3). Of the three fibrous structures, explained previously that make up a cell, the microfilaments play the largest part in the movement and migration of a cell. This means that actin is the vital component for cell movement. A fibroblast crawls by a leading protrusion, called a lamellipodium, which is where most of the cells actin is located. The actin is extremely flexible due its twisted, linked structure. The filaments clump / bundle together near the cell membrane, particularly at the protrusions such as the microvilli in an intestine lining epithelial cell. The actin penetrates in to the cytoplasm, where they become cross linked in to a three dimensional meshwork, governing the shape and mechanical properties of the plasma membrane and the cell surface. (4) . This means that the actin provides structural support, as well as movement potential for the cell. Filopodia are very similar to lamellipodia. They also protrude out from the mai n body of the cells like lamellipodia, and act like fingers for the cell to feel the environment around it and also to aid the detection of where the cell is supposed to migrate to. Filopodia have almost the exact same structure as lemellipodia, however have smaller protrusions and therefore contain less actin. They are about 0.1 Â µm wide and between 5 10 Â µm long, and each contains a loose bundle of 10 20 actin filaments, orientated with their positive ends pointing outward'(5), exactly like the orientation of the actin filaments in lamellipodia. However, filopodia are present around the whole circumference of the cell, not just protruding from the lamellipodium, which creates an even larger surface area for the cell to detect its surroundings. The protrusions grow by the growth of the actin filaments, where dimers are added to the positive terminals of the filaments. Although dimers are removed from both terminals, particularly the negative end, this is outweighed by the mor e rapid addition of actin at the positive end. The growth is a very quick process, which therefore allows the cells to move around the body at a fairly fast pace. Once the lamellipodium is protruded from the main structural shape of the cell, the newly produced bottom section of the cell then adheres to the surface it is moving along, hence pulling the rest of the cell along with it. At the same time, contraction occurs at the rear of the cell, then draws the body of the cell forward, in the direction the lamellipodium is protruding, in a process called traction. (6) Cell migration is extremely important to an organisms survival. It is essential for the movement of cells in the immune system, an example of which is a macrophage, which finds destructive cells and eats them. This is because it is vital for cells to be able to travel to the site of an infection in order to fight it and clear it up or to communicate with other cells, to let them know that there is a problem, which they can then sort out. Cells that can do this are called fibroblasts, which migrate through connective tissue, remodelling them where necessary and helping to rebuild damaged structures. (7). If this was not possible, the organism would be in serious trouble and could die or be badly damaged by very superficial wounds and mild diseases which are overlooked as non-serious in humans due to cells being able to migrate. The cell migration mechanism is vital to a macrophage, as its job is to move around the body, detecting and destroying harmful cells. If movement was not possi ble, the macrophage would only be able to detect destructive cells that were situated in the immediate vicinity, which means to successfully remove all harmful pathogens would be impossible. This would mean the organism would have very little protection against disease. Cells are also able to migrate by means other than by lamellipodium protrusions. Cilia are one example, as well as a male humans sperm, which moves by a tail like structure called a flagellum. The sperm is able to beat the flagellum, which is designed to move the entire cell, and instead of generating a current, they propagate regular waves along their length that propel and drive the cell through liquid (8). Unlike most other migrating cells in the human body as described above, the main component for movement in flagella is tubulin. Microtubules span the whole length of the flagellum in an axoneme, which contains two central microtubules that are surrounded by an outer ring of nine pairs of microtubules. (9). The movement is enabled by molecules of ciliary dyenin that form bridges between neighbouring microtubules around the circumference of the axoneme. (10) The end tail of one molecule attaches to a microtubule, while its other end, the head of the molecule attaches to another m icrotubule. This promotes a sliding mechanism similar to that of actin in the migration of cells with lamellipodium protrusions. Bacteria and cilia also have flagella, made of flagellin and dynein. The bacterial flagellum has a similar structure to a microtubule in the way that it is a hollow, tube like shape. Ciliary beating can either propel single cells through a fluid or can move fluid over the surface of a group of cells in a tissue (11). The second is apparent in the human respiratory system, where ciliated respiratory epithelium cells in the trachea prevent any foreign, potentially harmful particles such as dust and bacteria in the air from entering the bronchioles and lungs. They do this by acting like tiny hairs and by beating the saliva containing the harmful particles back up the trachea to exit the nasal cavities by coughing. If the cilia are unable to beat, it causes problems such as Kartageners syndrome or primary ciliary dyskinesia. Although this syndrome is extremely rare, it is a genetic disorder, meaning it is hereditary. Due to the respiratory system having little to no defence against dust and pathogens which enter the nasal cavities and then travel down the trachea and bronchi, harmful particles may enter the lungs. This causes infection and disease of the lungs, such as pneumonia or bronchitis. In conclusion, the presence of cell migration mechanisms in organisms as small as bacteria to the large, multi cellular organisms such as humans is extremely vital to their individual survival. Without such an important ability, cells would not be able to detect or fight disease, from minor superficial impediments to very serious illnesses. Reproduction in humans would not be possible and bacteria would find it extremely difficult to invade host cells for reproduction. Without cell migration, the whole human immune system would not be able to function correctly. Although the movement of cells is quite complex, it is only the beginning of a massive sequence of mechanisms in which cells can communicate with each other to orchestrate the correct workings of the human body.

Dorm Life Essay -- College University Education Student Essays

Dorm Life College can be great; living with your roommates can be a nightmare. But wait†¦Ã¢â‚¬ ¦before you throw in the towel, make sure you know and understand the rules of a dorm room. Dorm life is something almost every college student must experience. It’s not as easy as it seems either. Most of the time students will try to room with people they know, but normally a student can’t be that lucky to make that happen. It can actually be easier living with people who are complete strangers, than living with people that have been there through life. The first thing to accomplish is knowing the fact that in a dorm room, everyone has a job. Everyone in the room must provide certain things. For example, one should bring the refrigerator, the other, a microwave, and so forth. When things are brought, they are to be shared, that’s what living together is all about. Nothing should be secluded from each other, especially the necessities of the room. If a roommate decides not to share, then they should learn nothing will be shared with them, and should more than likely live alone, if they have a problem with sharing. This should apply to the cleaning of the room as well. Each roommate should separate the chores. It is true that it’s hard to keep the dorm room spotless, but a dirty room can make a persons living arrangement uncomfortable. Someone could be in charge of the garbage; another could be in charge of the dust, which dorm rooms do collect a lot of. Dr. Andrew Johnson, a writer of College Bound Magazine, talks about in his article about dorm issues. For example, with cleaning the room, if a roommate does not do his or her job there are tactics of solving the situation. He says, â€Å" The best way is t... ... to help you on a subject your not having the best of luck in. Roommates should be there to motivate one another and grow closer. Not to fight like five year olds, or kick each other out. It can be easy to void problems, and that’s by not starting them. Everyone needs to have in mind; College is an important time in your life. Be excited to actually be at college, and be excited of the change from home. Take a chance, have an open mind for many college graduates, best memories include their roommate. But always remember that a dorm room is just like a democracy, if a roommate can't compromise then it's going to be there loss, because they will not win.

the russian americans :: essays research papers fc

The Russian-Americans As of the last released comprehensive United States Census listing all nationalities, in 1990, there were over two million people claiming Russian ancestry living in America. Not included in this number was over one million people who were born in Russia. Sixty-six thousand entered the U.S. between 1980 and 1990 over 120,000 entered before 1980, slightly over 123,000 were naturalized citizens, and over 71,000 were not considered citizens of the United States. When it comes to income and occupation the Russian-American ranks higher on the socio-economic ladder then many minorities. When it comes to occupations over half of the Russian population is in the managerial or professional field, while another third of the population works in sales. The rest of the population works in the service or labor field with the smallest bit of the population being farmers, .6 percent. In correlation the median income of a Russian-American is over 45,000 dollars, only 3.6 percent of the population lives in poverty. This can be a direct correlation to the educational attainment of the Russian-Americans 90 percent graduate high school, 49 percent have a bachelors degree, and 24 percent have a graduate degree. This is one of the highest percentages of any group that has come to the United States, except some of the Asian countries. The Russians started to look for the American dream in the seventeenth century when Semen Dezhnev set out to find a route through the Bering Straight, although he never made it anywhere close to the United States, he did find the Northern-most point of Siberia, which is named after him. The next expedition was launched by Vitus Bering, and although he died while searching for America some of his crewmates did find the Aleutian islands and started the fur rush of 1973. In two years many fur industries were set up and people started to establish small communities in Alaska. In 1794 eight monks arrived to one of those small towns, Kodiak and started a Russian Orthodox mission. In seventy years when Alaska was sold to the U.S. the Orthodox religion was so ingrained into the people that it was, and still is the predominant religion in the area. After the sale of Alaska, the immigration of Russians slowed until the beginning of the twentieth century and the beginning of Communism is Russia. In the beginning it was mostly laborers and farmers and then came the former Russian army and naval officers, highly qualified engineers and scientists, actors and composers, musicians and painters, and a number of world-famous singers and ballet dancers.

All Grown Up and No Place to Go Teenagers in Crisis

Child and adolescent development specialist David Elkind contends that today's teenager’s are struggling as the result of a shift in society to a â€Å"postmodern† period. In this period, â€Å"the needs of children and youth are often weighted less heavily than are the needs of parents and the rest of adult society† ( xiii ). Elkind believes that, as a result, â€Å"we as a society have abrogated our responsibility to young people† (xiv).Elkind explains how, in this postmodern period, adults mistakenly treat teenagers as though they were already competent and sophisticated, and therefore do not guide them from childhood into adulthood, as youth were guided in previous generations. His words sound a clear warning to teachers and other adults who tend to confuse teenager’s' physical maturity with emotional, psychological, social, intellectual, and spiritual maturity. A useful feature is his discussion of how the â€Å"growth markers† that were formerly available to guide children into adolescence and teens into adulthood are now absent.Examples include girls of all ages now being encouraged to wear makeup and sophisticated clothes, and boys of all ages being encouraged to participate in high-stakes competitive sports teams. Teen’s perception of stereotypes varies from person to person. It is interesting to know that how teens identify groups and how they decide to associate themselves with particular ones, at a time in their lives when age-mates take on a greater significance and the influence of adults diminishes.Teachers should not ignore or underestimate the power of peer influence; although we commonly think of this influence in negative terms, this article helps us recognize that peer influence can be a positive contributor to teenager’s' classroom behavior, too. The role of environment in determining behavior is considered, much greater by the intellectual descendants of Locke. More than adherents of other schools, they see humans as substantially malleable; they are convinced that children's behavior responds to the expectations expressed for it.Thus, if we believe that teenagers will be moody and rude, our children are likely to comply; if we relegate them to a social holding pattern, they will adopt the general characteristics of powerlessness. The discipline of child psychology, as well as the children it studies, is influenced by cultural assumptions seems beyond doubt. But then, what is to be made of these conflicting views about the plasticity of development? It would hardly be feasible to attempt a grand synthesis of these positions. David Elkind, a longtime observer and scholar of child development and family life, sees in the modern family a â€Å"permeable† family.He discerns in the seeming imbalances and morbidities of postmodern families the stresses hammering at children and youth in the contemporary society and a new family form emerging, a form that is bas ed on values and sentiments that prepare its members to cope with this stunning array of pressures. Three sentiments and their resulting practices are particularly heartening from his point of view. To be sure, by the teenage years, parents must exercise most of their authority by stating acceptable alternatives and sticking to them, even if that means throwing a child out of the house.In a sense, then, we are no longer talking about the kind of parental control liberationists object to, but more subtle pressures generally compatible with their stand except insofar as they think teens have a right to financial support no matter what their behavior. Teens might also insist that drinking or doing drugs should be their own choice, just as it is for adults. But the reverberations both for themselves and for those about them suggest the desirability of pressing them to limit such activities in a way that might not be appropriate for adults.David Elkind has warned against pushing children too fast in an age-inappropriate manner. Latency-age children bear much of the burden of a faster-paced society. Adults are spending more time at work than ever before; children are shuffled between activities in part due to their parents' schedules. Children's time outside of school has become more structured; they participate in extracurricular pursuits at earlier ages. Doing nothing, as in â€Å"those lazy, hazy days of summer,† previously part of the culture of a child, is no longer promoted or valued. Some children no longer just go out to play, they have â€Å"play dates.† They are infrequently left free to explore what they would do if there were nothing to do. There is no time for daydreaming. Television and computers have replaced quieter moments. Rarely do you hear a child say, â€Å"Turn off the television. I want to read now. † In this speeded-up society, adults are resigned to Elkind's concerns; there is no turning back for today's children. Parent s may rationalize and say it is a good learning experience for an eight-year-old to be home alone. Elkind's recommendation is that given the stress imposed on them, children should be taught skills to help them cope effectively with what is expected of them.For example, the â€Å"latchkey† child should be offered assistance such as phone numbers for reaching a parent, the police, and a neighbor, and instructions on what to do in case of fire. Rituals and routines are important components in the structure of the middle childhood years. As children begin to organize and classify their knowledge, they come to depend on routines to help them consciously and unconsciously deal with new issues and experiences. Birthdays, secular and religious rituals, and common developmental milestones all help them to find their place in the world.They are seeking to be connected to the larger society through attachments in school, with their peers, with their teachers, in social activities, and in their families. Ironically, because teenager’s are continually redefining their thinking about self and their own value systems, they are highly vulnerable to believing in media myths. As such, outside-in problems manufactured by the media through the power of suggestion and constant repetition become teenager’s' inside-out personal problems In short, adolescence is the stage in life when children begin to question their own thinking in light of what others think of them as well as for them.In this regard, teenager’s' sense of thinking is not wholly independent of their social sense of self. Although as parents, researchers, and teachers, we may be aware of the variable nature of the teenager’s' thinking self, we may not realize that adolescence is a relatively new stage in human development. In colonial America, teenager’s served as a source of cheap labor. With the advent of modern industrialization, longer periods of schooling have been requi red to prepare children for the workplace. This, in turn, has extended the time that children are economically dependent on their parents.As children enter the teenage culture, they are drawn away from their parents and into peer groups. In the process, teenager’s' developing social sense of self is placed into a tug of war between the norms and pressures of parents and friends. Adolescence in America is the psychological equivalent of toddlerhood. Just as toddlers move away from their parents physically, so teenager’s move away from their parents emotionally There are continuous negotiations between parents and children about distance. Children want to explore and parents want to keep them safe.And both toddlers and teenagers are outraged when their parents don't agree with them about the ideal balance of freedom and security. As teenager’s turn to their peers for validation and support, they often engage in intense experimentation, exploring a wide range of po ssibilities that often contradict parents' cherished beliefs in behavioral norms. In the process, teenagers may become the biggest enforcers and proselytizers for their own peer culture: Teenagers may punish other teenagers for failing to achieve the same impossible goals that they themselves are unable to obtain.Moreover, they may rush to set standards to ward off the imposition of others' standards on them. All the while, the content of the standards may remain variable often depending on what standards the media is marketing at a given time, from baggy pants and body piercing to tattoos and the latest neon hair styles. Teenager’s' social sense of self invariably leads to contradictions, as does their thinking sense of self. Social self-contradictions arise from teenager’s' membership in multiple groups that maintain different expectations and norms.More importantly, contradictions continually arise as teenager’s switch their loyalties from one peer group to t he next, giving rise to competing allegiances. In sum, teenager’s experience contradictions inside-out in terms of their thinking sense of self as well as outside in terms of their social sense of self. In many instances, the frustrations of these contradictions are further exacerbated by the academic sense of self that schools promote. One of the most visibly striking transformations during adolescence occurs as a girl's body changes in size and shape.Girls tend to appear rounder as their hips widen, and fat develops in the breasts, thighs, and buttocks. As these changes occur, culture tells girls that thinness is beautiful, even imperative. Not surprisingly, it is also during this period that girls become increasingly concerned with their bodies. Girls' changing bodies provide powerful stimuli to the self and others. A pertinent issue during early adolescence is that bodily changes bring about a sense of fragmentation in body image. Thus, the body is frequently depicted as a collection of individual parts, such as breasts and hips.So, for example, many girls this age worry about the size of their breasts. In the United States, bigger is generally considered better, yet not from girls' perspectives. Rather others are believed to hold that value. Because the body is often times viewed as a reflection of the self, the eroticization processes through which the body is transformed into a sexual object become a major source of conflict for many teenager girls. Teenager girls continue to suffer in multiple ways as a result of these complex social processes.Meanwhile the psychologists and psychiatrists who have historically led the study of what is known as â€Å"body image† have done so in ways that limit knowledge and understanding of girls, further contributing to the structures supporting domination and oppression of females. That is, these researchers have almost exclusively studied â€Å"body image† through quantitative measures that assum e objectivity. In the process, they have conveniently and openly ignored and dismissed contributions from social scientists and feminists who have studied the body from alternative and more hopeful perspectivesNevertheless, body image work has become influential, creating at least three problems. First, the historical study of â€Å"body image† has contributed to the objectification of the body. Second, â€Å"body image† researchers have created a logic of pathology to explain girls' problems Result of irresponsible sexual activity is substantial teenage motherhood. Yet the consequences of early childbearing are extremely damaging. Pregnancy doubles the risk that a girl will drop out of school; most such girls never return, regardless of their financial situation or ethnic background.Once the child is born, the girl is unlikely to be in a position to earn more than welfare would offer her and she has the responsibility of a child to boot. But if she chooses to go on we lfare, her sense of agency and independence is seriously damaged. If she marries instead, she is not only unlikely to finish her schooling but also faces a significantly higher probability of divorce than a woman who waits until her twenties to marry. Thus girls who engage in unprotected sex and who elect to keep their babies are at serious risk of a worse life than they could otherwise have expected.â€Å"But the damage does not stop there. The plight of their children is painful. Neither parent may take responsibility: they may be ignored by their fathers and handed to some female relative by their mothers. For the child, this may be a blessing in disguise, as the most irresponsible teens are those least likely to possess the qualities required for good childrearing. As these babies get older, however, they show the effects of their unfavorable environment. Children of teen mothers score worse on ability tests, get worse grades, and expect less in the way of education than childr en of older women.They also get less education, marry earlier, and divorce more often†. (p. 133) David Elkind questions the popular conception of parental authority Exerting parental authority doesn't mean that we can't play ball with our children or joke with them or have fun with them. Being a parent doesn't mean being an ogre or a relentless disciplinarian. Rather it means asserting ourselves as adults who have more experience, knowledge, and skill than our offspring. Children and teenagers are young and inexperienced. They very much need and want guidance and instruction from us. (205)At least three areas of concern arise from the literature about violence on television. The obvious ones are the relationship between television violence and aggression, even if the aggression is not directed against society, and the desensitization of children to pain and suffering. The less obvious one is the potential for children who are sensitive and vulnerable to become more fearful and insecure upon exposure to violence on television. â€Å"Television has brought murder into the home, where it belongs† (Elkind, p. 103). Murders and crime occur about ten times more frequently on television than in the real world.A third of all characters in television shows are committing crime or fighting it, most with guns. It becomes, therefore, a chicken-and-egg question. When one examines violence in films the trend towards increased gore and explicit horror is easily documented. Rather than reflecting the content and meaning associated with myths and fairy tales, horror films today are pure sensation with little serious content. If violence on television is controlled, children and adults will still be able to experience violence vicariously through other media such as films, books, and recordings.The contemporary challenges that have created this increase in stress among today's teenager’s, in Elkind's terms — the â€Å"perils of puberty,†  "peer shock,† and â€Å"family permutations†. Authentic parenting is an outgrowth of shared parenting but integrates unilateral and mutual authority depending on the concern at hand and the developmental stage of the child. But it is also leavened by a realization that each parent can perform their roles in ways that are true to their own temperaments, personalities, and experience. Finally, there is an emergent relationship between community and family.How well a family does is seen as partly dependent upon the ties it has with the community and the resources and assets available in the community. Community service has become a part of the required curriculum in many schools. Other neighborhoods are reaching out to isolated families or individuals and families in trouble. Some schools have become â€Å"lighted schoolsâ€Å"—twenty-four-hour family resource centers providing programs, services, and opportunities for connections to others. According to Elkind, i nterdependence is a central value and sentiment that underlies this emerging family form.â€Å"Interdependence is founded upon a sense of being both one and many, of being different from everyone else and like them at the same time† (p. 220). Traces of his longing for the modern family aside, Elkind's thesis about the new family embodies some of what we know about family resilience to this point. And it can apply in spirit to all families and caretaking relationships. It is important, as a starting point, to realize that every family, even those in the midst of gripping disorganization and bewildering turmoil, has strengths and capacities.Every angry, demanding parent has moments of caring; every confused teenagers has moments of hope and clarity; every abusive father has a twinge of doubt or regret. At some time in every family's life there have been periods of relative calm and stability. Every family has overcome hurdles, some more successfully than others. All of these ar e resources to be drawn upon, by the family members themselves or by someone who would deign to be of help to them. Works Cited Elkind David. ( 1998).

Should Conventions Be Made Law in the UK?

Conventions, in their own right, have a significant place in the constitution of the United Kingdom; despite being separate from the law and possessing only non-legal power, they allow a vast degree of control over the administrative responsibilities of the government. The degree to which the spirit of conventions can be enforced has always been a question of debate, as has the exact nature of that spirit. In their unwritten and uncodified form, conventions leave a great deal to be decided by contemporary views and the opinions of those in Parliament, which allows them to be both dynamic and reflective of current times. The questions remains, however, of whether this set of social rules ought to be provided the force of law, and by doing so, adopting them, with a certain degree of permanency, into the constitution of the United Kingdom. To determine whether conventions should be made into law (in their entirety or otherwise) we have to consider what conventions are, how they are different from laws, what it means to provide them legal force, and why, up until now, they have remained largely uncodified. According to A. V. Dicey, conventions are a collection of understandings and practices that control the conduct of members of the sovereign power, but which are not laws since they cannot be enforced by the courts. The evolution of constitution, over hundreds of years, has given rise to the current face of conventions, and it is prudent to wonder whether the natural development of conventions—with changing times and culture—should be halted through an incorporation of these understanding s into Acts of Parliament. The UK has never had historical interruption in the development of its constitution significant enough to warrant a written constitution; it has formed primarily through Acts of Parliament, Royal Prerogative and conventions. For conventions to be made into law, they must first be codified in a fashion that clearly delineates the spirit of the powers meant to be given statutory force. It raises a number of issues, chief amongst them the question as to which conventions will be made into law and which will not. The political implications of such a choice are many, considering the almost bipartisan nature of the UK Parliament. Where one party might see a convention as illustrative of modern needs, another might consider it outdated and not suited to becoming law. The Australian experiment in the 1970s resulted in a similar problem concerning the exact power of the conventions and their functions. What is to happen to those conventions which are not incorporated during the codification process? The Australian experiment led to the conclusion that the elegance of conventions lay in their flexibility and capacity to adapt with changing times. Even through the act of codification, the Parliament would fetter whatever dynamic nature conventions have by stating clearly where the boundaries lie; it would rid them of the nuances made available in their uncodified form. Conversely, supporters of legalizing conventions believe it is ill-advised to leave rules of such importance, which complement and bolster constitutional laws, undefined and without the power of courts behind them. In terms of liability, integrating conventions into Acts of Parliament will lead to a stricter and legal punishment for any breach of convention. The doctrine of ministerial responsibility concerns itself with accountability of cabinet ministers for the actions of their ministries and with how cabinet members must show a united front when it comes to collective decisions of the cabinet. Ministerial responsibility is governed by the power of conventions and any action contrary to it would likely lead to sanctions and the scrutiny of the public. The non-legal nature of conventions prevents criminal liability; however, the same cannot be expected if statutory force is given to these rules. By making conventions law, it will be expected that any violation of that law will be punished by the courts, which may even threaten the separation of powers. It will be in the hands of judges to punish members of Parliament and the executive who are seen to have failed to perform some duty or another that would have previously fallen under the purview of conventions. The provision of legal force to conventions would most certainly lead to a more thorough understanding of government regulation and perhaps provide a more stringent balance to governmental power. However, I believe not all conventions should be made into law. Codifying conventions will lead to conflicts as to which conventions are to be incorporated and will reduce their variable nature and capacity to accommodate changing times. Sir Ivor Jennings stated that conventions provide the flesh that clothe the dry bones of the law. He also said they kept the legal constitution in touch with the growth of ideas. By giving conventions statutory force, the Parliament will deprive it of that quality. Conventions can serve their purpose only by remaining unenforceable rules of conduct rather than laws written in stone.

Cooking and Food Safety Measures Essay

Q1 – Identify potential food safety hazards when preparing, serving, clearing away and storing food and drink. People can get sick if the food they eat has harmful chemicals or microorganisms. This is called food-borne illness. The goal of food safety is to prevent the hazards that cause food-borne illness or injury. Most of the hazards in food are things you cannot see, smell, or taste. – Physical hazard: Hard or soft objects in food that can cause injury. For example, broken glass, jewellery, staples and fingernails. – Chemical hazard: Poisonous substances that occur naturally or are added during food handling. For example, cleaning products and pest control chemicals. – Biological hazard: Germs that cannot be seen without microscope. For example, parasites, viruses and bacteria. ( Preparing: – While preparing food, food workers must remove watches, rings, bracelets, and all other jewelry on the arms or hands. – Using the same cloth for cleaning surfaces used for both raw, i. e. meat and poultry, and ready to eat foods – Physical contamination e. g. flies, jewellery, broken glass and equipment in bad condition. ( Storing: – Store raw meats at the bottom of the fridge to prevent meat juice dropping on the other food – Eggs will be stored under refrigeration in order to reduce the growth of Salmonella – No cleaning materials should be stored where they may come into contact with open food. – Dried foods will be decanted into seal-able containers in order to protect from physical and chemical contamination ( Serving: – Serving Ready-to-eat food (e. g. sliced fruit, cooked pizza, bread) without additional washing or cooking to remove microorganisms. – Must use utensils such as tongs, scoops, deli papers, or single-use gloves to keep from touching ready-to-eat foods. – You place food and drink within easy reach of the individual – You serve food and drink with the appropriate utensils and in a hygienic manner ( Cleaning away: – Food-contact surfaces should be washed, rinsed, and sanitized after each use. – Scrape excess food into a rubbish bin – Leave dishes and cooking utensils to air-dry or wipe with clean dry cloth. – Rinse in clean hot water – Encourage individuals to wash their hands and clean themselves. Q2 – Explain the importance of implementing food safety measures when providing food and drink individuals. Every day people all over the world get sick from the food they eat. This sickness is called food-borne disease and is caused by dangerous microorganisms or chemicals. The importance of implementing food safety measures when handling food and drink is to keep children and young people safe from food-borne illnesses. Q3 – Explain why personal protective clothing should be used when handling food and drink. Personal protective clothing should be used to protect the wearer from specific hazards of a hazardous substance. – PPE includes gloves, respiratory protection, eye protection, and protective clothing. – You should always wear gloves to minimize the chance of bacteria entering the food from unclean hands. – Gloves must be changed each time you do a different task, e. g. preparing sandwiches then going into walk in cooler-touching different contaminated surfaces. – Aprons and chef jackets are a great way to prevent any of your clothing from contaminating the food. – Hairnets and hats are used to prevent hairs from entering food and drink. Q4 – Explain why surfaces, utensils and equipment must be cleaned before beginning a new task. Surfaces, utensils and equipment must be cleaned before beginning a new task to prevent cross-contamination. Cross-contamination is one of the most common causes of food poisoning. It happens when harmful bacteria are spread onto food from other food, surfaces, hands, utensils or equipment. Q5 – Explain the importance of clearing and disposing of food waste promptly and safely. Food waste must be disposed of on a regular basis. This helps to prevent cross contamination. Pests such as flies and insects love leftovers. There is also the added risk of attracting mice and rats. – Food waste and other refuse must not be allowed to left in food rooms, except so far as is unavoidable during the business operation. – It is good practice to remove all waste from the food room at the end of the day. – Food waste and other refuse must be deposited in closable containers. These containers must be of an appropriate construction, kept in sound condition, and where necessary be easy to clean and disinfect. – Adequate provision must be made for the removal and storage of food waste and other refuse. – Refuse stores must be designed and managed in such a way as to enable them to be kept clean, and to protect against access by pests, and against contamination of food, drinking water, equipment or premises. – Refuse should be removed frequently and, depending on the size and type of business more than one collection/removal per week may be required. – Storage facilities must be kept in a clean condition and the waste must be protected from rodents or birds. Q6 – Explain the importance of storing different types of food and drink safely. The importance of storing different types of food and drink safely is to avoid cross contamination and ensure a good rotation of stock. In the UK we end up throwing away 8. 3 million tonnes of food and drink every year and most of this could have been eaten. There are simple things you can do to reduce waste – to try to make sure you don’t buy or cook more food than you want to eat. Some food needs to be kept in the fridge to help stop bacteria from growing on it, such as food with a ‘use by’ date, cooked food and ready-to-eat food such as desserts and cooked meats. – Keep food covered to protect it from contamination from raw foods and physical objects – Always store â€Å"cooked† food above â€Å"raw† meat in the refrigerator this will eliminate the risk of contamination from bacteria and meat juice spillage to other foods. – Do not store food in open cans because when a can has been opened and the food is open to the air, the tin from the can might transfer more quickly to the can’s contents. – Do not overstock the refrigerator, as this will affect the airflow around the food. You can keep food safely in the freezer as long as it has stayed frozen the whole time; however, the taste and texture of food changes if it’s frozen for too long. It should be all right to freeze most raw or cooked foods. – Freeze it before the ‘use by’ date – Follow any freezing or thawing instructions on the label – Defrost it in the fridge so that it doesn’t get too warm. – Ensure food is thoroughly defrosted before cooking food Many types of food don’t need to be kept in the fridge to keep them safe to eat, for example dry foods such as rice, pasta and flour, many types of drinks, tinned foods, and unopened jars. But it’s still important to take care how you store them. – Try to keep food in sealed bags or containers. This helps to keep them fresh and stops anything falling into the food by accident. – Don’t store food or drinks near cleaning products or other chemicals. – Don’t store food on the floor, because this can encourage mice, ants and other pests. – Remember that some types of food might need to be kept in the fridge once you’ve opened them – follow any storage instructions on the label. Task 2 Q1 – Identify sources of information about food safety. – Food Safety Education – Food safety training – Research and development Q2 – Describe how to access and support about own role in maintaining food safety when providing food and drink for individuals. – Talking to teacher or leader of placement – Listen and take notes – Making posters.

Advanced Manufacturing Processes and Materials (Turbocharger)

Turbocharger is nothing but a gas compressor, which is kept in use to forced-induction of the internal combustion engine. It is a derived form of supercharger. The fundamental function of the turbocharger is to enhance the density of the air which is entering in the engine. Density is increased to produce more power.Compressor, turbine and shaft are the core and essential parts of a turbocharger. Compressor of the turbocharger got power by a turbine and this is driven by exhaust gases of the engine. Direct mechanical drive is not used like many other superchargers.In early days or in the days of the invention of turbochargers, it is referred as turbosuperchargers because turbochargers were derived from the superchargers by combining a turbine in the accessories of superchargers. Compressor was there in the superchargers, but turbine was not present in superchargers.In turbochargers, a fan pump of small radius comes into the driving condition with the help of the gases which get exhau sted by the engine. The main assembly parts of the turbochargers means turbine, compressor and shaft are attached in such a way that turbine and compressor shares a shaft and get attached with it.The turbine is used to alter the exhaust heat and pressure into the rotational force and this rotational force drives the compressor. Compressor increases the pressure of the air and this pressurized air enters into the cylinders on each intake stroke. This in turn increases the volumetric efficiency of the engine and this is done by solving one of its cardinal limitations.Only downward strokes of a piston are used in naturally aspirated automobile engine, but the pressure of the atmosphere can not be increased more than 1 atm. This thing creates a pressure difference limit in the naturally aspirated automobile engines, which limits the amount of airflow entering the combustion chamber.But turbocharger eliminates this limit because it is designed in such manner that it increases the pressur e at a particular point from where air enters into the cylinder. This in turn maintains pressure into the combustion chamber, which increases the revolution speed. This increasing speed produces high power and torque at the output of the engine.But there is a limitation on the pressure in the turbocharger. Pressure should not cross its critical limit, otherwise explosion and physical damage may occur in the engine. To avoid such type of conditions an arrangement has been made there in the turbocharger. In this type situation intake pressure is being controlled by venting excess gas and this facility is being provided by wastegate functionality.

A Biography of Sidney Poitier

In 1967, a press conference with Sidney Poitier, at that time one of the most successful and popular American actors and certainly the most famous African-American actor, turned from his many roles on screen and stage and became something else entirely.Due to a rash of racial riots across the nation at that time, Poitier was asked pointed questions concerning whether or not he was in favor of the racial riots, his theories on segregation, and other racially oriented topics (Goudsouzian).It was at that point that something happened which changed the course of Poitier’s life as well as the role of African-Americans everywhere- rather than avoid the question, turn the focus back to his fame or storm off in a rage, Poitier came to the realization that it was impossible for him to separate his status as an entertainment icon from his obligation to use his fame to advance the cause of minority rights in America.   Since then, Poitier has done just that.This research will discuss A ram Goudsouzian’s pivotal 2004 biography of Sidney Poitier, not only as a review of this book, but also in an effort to try to better understand how and why Poitier has become one of the most influential African Americans since the end of Civil War.Author’s PurposeWhen gaining a better understanding of why Goudsouzian chose Poitier as the subject of his book, one not only gains an understanding of the author’s purpose in writing the book, but also a grasp of the major social and historical issues that are tackled through a book which is biographical at its core, but becomes much more expansive as it unfolds.First, one must realize that Goudsouzian is not a biographer by nature, but in fact is a history writer, which is why Poitier was chosen as the subject of the book.By choosing a pivotal historic African-American who bridges the gap between the faà §ade of Hollywood and the real world of the urban streets of the nation, Goudsouzian has been able to tell not o nly the story of the struggles of an ambitious African-American man coming of age in the racially charged 1950s and 1960s, but also of a man who parlayed his fame not into a mere vehicle for his own enrichment, but to try to aid and support his entire race.Goudsouzian’s Central ThemeEarlier, the point was made that Goudsouzian’s book is much more than biography or history, but is rather a powerful combination of the two.   Looking beyond this assertion, it is also interesting to explore the central theme of the book, which can fairly be identified in one word-perseverance.For Poitier, perseverance has meant the constant jumping of hurdles, placed in front of him by a society which still wrestles with the issue of equality for African-Americans, even decades after the strife which advanced African-Americans significantly, and almost a century and a half after a bloody Civil War which settled the issue of African-American freedom once and for all.   For African-Ameri cans in general, it would seem that Goudsouzian paints perseverance as a struggle to gain equal footing with the mainstream of America.This being said, however, a fair critique of Goudsouzian’s approach is in order.   It would seem that the author is too quick to always portray Poitier, and African-Americans as perpetual underdogs who never gain any significant ground.However, in truth, much progress has been made in cause of racial equality, while keeping in mind of course that there is much progress yet to come.   Goudsouzian could have presented a bit more of a balance in his contrast.

Aesthetics- Philosophy of Art Essay Example | Topics and Well Written Essays - 1500 words

Aesthetics- Philosophy of Art - Essay Example In aesthetics you have to see for yourself precisely because what you have to "see" is not a property: your knowledge that an aesthetic feature is "in" the object is given by the same criteria that show that you "see" it. To see the sadness in the music and to know that the music is sad are one and the same thing. To agree in the judgment that the music is sad is not to agree in a belief, but in something more like a response or an experience" (Eldridge 145: 2003).It has long been recognized that human beings find a variety of visual and auditory appearances to be extremely fascinating. Certain sunsets, flowers, birdsongs, and beautiful bodies, among natural things, and certain pots, carvings, vocalizations, and marked surfaces, among humanly made things, seem to engage eye or ear simultaneously with thoughtful mind. In experiencing such things, we feel we want the experience to continue for "its own sake, " at least for some further time. The Greek uses a phrase to kalon which means the fine, the good, or the beautiful, to describe many sorts of things that are attractive to mind and eye or ear, without sharply distinguishing natural beauty from artistic merit (or moral goodness). "In the Symposium, Socrates reports that the priestess Diotima once instructed him in how a lover who goes about this matter correctly must begin in his youth to devote himself to beautiful bodies, first loving one body, then many (as he comes to understand that they are alike in beauty), next beautiful minds, beautiful laws and customs, beautiful ideas and theories, until finally he will come to love the Beautiful itself, absolute, pure, unmixed, not polluted by human flesh or colors or any other great nonsense of mortality." (Eldridge 47: 2003) In pleasing us, natural and artistic beauty, according to Kant, serve no outer purpose. The experience of beauty does not yield knowledge, and it does not of itself enable the satisfaction of desires for material goods. Yet it is not nonetheless merely agreeable or pleasant; instead, the experience of beauty matters. Beauty in nature makes us feel as though the natural world were congenial to our purposes and projects. In feeling the beautiful natural object to be "as it were" intelligible or made for us to apprehend it, we further feel that nature as a whole, which seems to "shine forth" in beauty, is favorable to our cognitive and practical interests as subjects. To experience a beautiful sunset, according to Kant, is to feel (though not to know theoretically) that nature makes sense. Kant's terminology may be difficult, the experience he is describing is a familiar one. Beautiful objects of nature or art engage our attention. We love them by paying active, cognitive attention to t hem, even if we do not get anything from them or even if it brings out the inner most emotions from us. The above discussion brings us to compare art with emotions, the reason why identifications with artists and imaginative participation in experiences and emotions are available to us is that works of art are made things, products or instances of human action. To understand an action, including actions of artistic making, is to understand its suitable motivation by reasons in contexts. Actions of artistic making, including the making of both narrative art and non-narrative art, are concerned with the shaping of materials to hold attention on a presented subject matter. (In abstract work, the presented subject matters are often centrally the perception and gestural action of the artist and the possibility of the audience's imaginative participation in that perception and gestural action.) Whatever emotions figure in attention to this subject matter are emotions that members of the audience are solicited to experience and explore, as they participate in the attention that is embodied in the work. The understanding of art is much related to exploring, to understand art critically is to explore it imaginatively, guided by a range of relevant

Quality Outcomes Framework (measuring client outcomes in disability Research Paper

Quality Outcomes Framework (measuring client outcomes in disability and out of home care services) - Research Paper Example On the other hand, children with a disability/disabilities are those children who suffer an impairment in their health, communication, movement or learning, which adversely impact their social engagement and education (Australian Bureau of Statistics, 2012). Identification of National Standard of Quality Outcomes Model Out of Home Care Program for Children and Young People Ideally, the Best Outcomes Model was conceived to specify the best possible results for the Out of Home Care program for children and young people. While it is preferable and is even possible at the institutional level, as of this writing the Best Outcomes for Out of Home Care has not yet officially been specified for the national level. Efforts, however, are underway for the determination of the National Standards for Out of Home Care, which is in its consultation stage under the auspices of the Australian Government Department of Social Services. The aim of the National Standards for Out of Home Care is to  "drive improvements in the quality of care so that children and young people in care have the same opportunities as other children and young people to reach their potential in all the key areas of well-being.† These key areas of well-being referred to for children, young people and the disabled include health, safety, culture and community, spirituality, emotional development, learning and achieving (Australian Government DSS, 20 Aug 2013). The National Standards aims to identify the key factors in the delivery of care that directly impact upon the positive outcomes of quality of care for children and young people. Presently, there are 13 standards which comprise the National Standards for out-of-home care, and measures have been identified by which outputs could be gauged against these standards. The hope is that measurable standards will be defined and set at the best practice level, to ensure that all legal jurisdictions in Australia are aimed at driving improvements consis tent with each other. These factors that may form the bases for standard setting include (Australian Government DSS, 20 Aug 2013): Stability of placements and relationships Regular health and well-being checks Transition planning that involves children and young people (i.e. into during and existing care) Appropriate carer assessment, screening, training and support By setting the standards and defining the best practices, the goal of defining the desired outcome for children in care, in a manner that is identifiable, measurable and therefore capable of objective assessment, becomes possible. These desired outcomes for children in care, herein identified according to their respective areas of well-being earlier specified, include: Health, both physical and mental Attain and maintain good health Develop effective coping style Safety A stable environment that is free from physical, emotional and/or sexual abuse Develop social connections Learning and achieving Achievement of developme ntal milestones Participation and achievement in education Emotional development Stability in behaviour Positive and supportive relationships Culture and community Cultural identity and ethnic pride Participation in community Spirituality Positive sense of identity Connection to family

Role of Homemakers Essay Example | Topics and Well Written Essays - 500 words

Role of Homemakers - Essay Example This is a predominantly principled debate that proposes that every homemaker should earn an equal salary from the government fund that is funded through taxpayer dollars. This can only be performed through tax rebates and tax exemptions that can be doled out through institutionalized processes set up for tax returns and auditing. A good example is America’s Internal Revenue Service or the Canada Revenue Agency based in Canada.The life of a homemaker entails a boundless amount of to-dos and demands. Provisional to the size of family and home, the position can extend beyond the typical 9 to 5. Way back in the 1950s, homemakers were anticipated to stay at home, while those who desired to work faced frequent stigmatization. Currently, it is the opposite of what used to happen: whereby women pity one another along the fault lines of economic class, conviction, ethnicity, and need. In the majority of developed nations, homemakers who stay at home are considered old-fashioned as well as an economic burden to the society. Observations from Lui, 2013, reveal that the daily chores of cleaning, raising their children, and cooking by these homemakers have continuously been ignored by national accounts. The majority believe that G.D.P. will go down if a man marries a homemaker and stops paying her for her work. In addition, G.D.P. will rise if a homemaker stops nursing and buys formula for her little baby. The United Nations, 2001, has noted that homemakers have been valued less than ever in a debated that equates women to men in raising productivity and economic growth through the labor market and labor market. Homemakers do face punishment in nations where mothers still struggle to balance career with family and thus quit work less out of conviction than necessity.

Philosophy - Aristotle vs Plato Essay Example | Topics and Well Written Essays - 1250 words

Philosophy - Aristotle vs Plato - Essay Example But essentially at a point their philosophies are almost the same because both them doubt the physical reality while their solutions for the believability of reality are different. Indeed Aristotle’s belief in reality emerges from the experimental proof. But Plato’s belief in reality is mostly contextual. For example, if it is believed by the most of the people, it is the reality for the time being. Even if one meets a more real thing, it will not be established by until others also feel in the same way as the person who has viewed the more real/realer. Therefore, Plato’s reality seems to be the norms followed by the most. Plato asserts that reality is essentially subjective and normative while Aristotle’s reality is objective and in order to earn the credibility, it needs to go through a set of experimental process. Indeed both Plato’s and Aristotle’s philosophies are complimentary to each other in the sense that the escaped prisoner discovers the reality through Aristotle’s experimental process that symbolically represents the prisoner’s attempt to escape from the cave, though in Plato’s allegory, the escapade of the prisoner happens accidentally, and the escaped prisoner must teach other prisoners in order to drive out the reality of the cave from their head, while establishing his own reality. In Plato’s Allegory of the Cave, the prisoners’ cognitive perception of the shadow reality can be considered as their knowledge of the Cave. That is, Plato knowledge is related to physicality, and reality is absolutely the Ideas that precedes reality. P lato’s theory of Ideas and knowledge suggests that â€Å"states of being are contingent upon the mingling of various Forms of existence, that knowledge is objective and thus clearly more real, and that only the processes of nature were valid entities† (Thomas 23). In this regard, Richard L. W. Clark says that in Plato’s hierarchical model of cognition, â€Å"empirical

Sustainable tourism - Assignment Example Cost savings linked with tourism industry are management of resource, energy, waste and water. Resource management enables customer service and comfort. The benefit of recognition and cost savings is closely knitted with the concept of sustainable organization. In past few decades there has been increasing awareness regarding social or environmental impacts caused by hotel operation and development. Sustainability issues are greatly driven by wide array of factors like desire of operator or owner to decrease operational costs, alter attitude of investors towards environmental conditions and regulatory forces imposed on facility development. The sustainability aspect aims at balancing social, environmental and financial factors in order to undertake appropriate decision making process over an extended period of time. In this study tourism industry of Australia would be clearly portrayed. Sydney is regarded as the largest city of Australia. This location comprises of vibrant national p arks and pristine beaches. Radisson Blu Plaza Hotel based in Sydney is a preferred tourist destination. This hotel offers 26 luxurious suites along with 336 stylish rooms. Radisson Blu Plaza Hotel offers superior quality accommodation and award winning restaurants. There are other features which add value to this hotel operation. This study would outline this operation, its sustainability issues and recommended ways to eradicate such issues. Tourism industry can be sustainable only when it takes into account social, environmental and economic factors. The Australian hotel industry is one of the major economic drivers at national, local and state level. There are almost 30,000 individuals who are provided jobs by hotel industry of Australia. In economic context, Australian hotel industry generates $14 billion. The hotel industry can efficiently contribute towards national economic development. Long term strategy

Create a report consisting of an advice package which offers Essay

Create a report consisting of an advice package which offers guidelines, advice and practicable recommendations for implementing and managing large databases - Essay Example Database technologies are evolving to address the issue of handling large databases. These technologies are dynamic, but the fundamental principles and skills remain the same. Many purveyors are addressing the need for databases that support huge amounts of data; usually in the petabyte range (> 1,000 terabytes) (Kavanagh, 2004). Information technology is dynamic; data is collected as hardware and software advance to handle bulky data. This makes it difficult to define what a large database entails. What is large today will be tiny in the next ten years. A large database can be defined as follows; Implementing and managing large databases has been a problem for most companies. Companies ought to examine and evaluate their database design, to identify the inherent inhibitors to a seamless database management system. The size of a database is influenced by the data volume, hardware, throughput, and software (Dittrich, 2001). Data volume is represented by table numbers, and/or the size of the data. A small database running on a constrained server will portray characteristics of a large database. Throughput is the measurement of usage levels. If a small database serves 9 million users simulataenously, it will be termed as a large database. The software used explains the database management system employed, as well as its implementation. The database is only good at the weakest point of the four factors. These weaknesses can be compensated in various ways: In deciding how to scale a large database, there is the scale-up and scale-out options. Scaling-up is not a preferable option in the modern day of database management systems. Large servers tend to have an adverse price to performance ratio, when compared to commodity machines. The performance for every dollar expended on high-end servers is usually low. The next best alternative would be to scale-out. Upgrading a

RNA silencing for the prevention of Phytophthora root rot in avocado Literature review

RNA silencing for the prevention of Phytophthora root rot in avocado - Literature review Example So, the scientists and the concerned people have found out a way to tackle this menace [2]. It is the use of RNA. The RNA is used to inhibit specific gene expression of the plants to prevent Phytophthora root rot in avocado plants. It was further found that the growing population is causing a sharp increase in the demand of the avocado across all over the world [3]. In order meet the rise in the demand, the farmers or the cultivators are using a number of elements to increase the production of the avocados. Overuse of the elements is further affecting the plants. The plants are getting affected by pests. Among them the rot root fungi is the most common form of the pests. Excessive spread of the fungi would destroy the crop and highly affect the cultivation of the crops so the scientists have discovered a number of methods which would prevent this. Among them RNA slicing is one of the most common methods for the prevention of Phytophthora root rot in avocado. According to a study, it was found that the Phytophthora root rot in avocado is primarily caused by Phytophthora cinnamomi, which is an economically important disease in the avocados around the world [1]. The crops when affected with fungi and gets harmed with Phytophthora root rot, it completely destroys the crops and leaving co crop for sell and make money out of it. In Australian agriculture, economic cost of losing were estimated in previous 20 years to be more than AUS$200 million per year [] and around US$44million in California annually []. The RNA silencing is used to increase the resistance of the avocado trees with the help of transgenic rootstocks. It is expected to reduce the incidences of fungi attack on the avocado plants. It was found that the fungi attack on the avocado trees could be prevented with the help of RNA interference process [4]. The authors further explain RNA interference as a cellular process where the RNA molecules
