Honesty: Lie and Friendship Relationship
In a friendship relationship honesty is the most important trait one should have. Although many traits such as respectfulness, trustworthiness and caring are also important to have one believes that honesty is the number one trait. Honesty means telling the truth, having good intentions and being sincere. To establish a friendship relationship one should be able to believe in each other. An example of this is believing in each other is when a friend borrows money and they say they will return it the next day. They are giving their word. If they just keep the money and never return it to back then they are considered to be a dishonest person and the friendship can fall apart. Instead they should be honest and tell the truth of why they couldnââ¬â¢t return the money and maybe the friendship could be restored. Having good intentions speaks about having good character. When one has good intentions then one can be believed in. For instance if a friend tells another friend that a particular person has a crush on them, this action may cause resentfulness because they may have a crush on another person. Even though the intentions were good intentions the actions could become disastrous because the relationship will be broken. Another form of honesty is if one goes into class and a cell phone is left behind on a chair; what would one do: A: keep it or B: tell the teacher? On one occasion this was, while entering the classroom one found a cell phone and one gave it to the teacher. By making the right choice oneââ¬â¢s peers were able to identify oneââ¬â¢s honesty. Setting a good example is the best thing to do. Not everyone is as honest, on one occasion oneââ¬â¢s phone was stolen from oneââ¬â¢s backpack, one was very unhappy. Due to not having enough money to purchase another cell phone one has had to adjust to life without a cell phone. There are many dishonest people everywhere. Oneââ¬â¢s belief is that if the item doesnââ¬â¢t belong to one then one must return the item. Being sincere with each other is building a positive relationship. No matter how difficult it is to tell the truth one is better off being sincere than to lie about it. The friendship may be hindered if the truth is not said as it occurs and the friendship may be lost. When one lies about things then one continues to lie very easily to others in fact one can actually think that one is telling the truth. One guesses one can become a compulsive liar. By always practicing telling the truth one will not have those types of problems. In conclusion, the reader may not agree to above essay, yet one believes that honesty is what keeps a friendship relationship in good standards. Being sincere is to tell each other the truth no matter how difficult it may be. By being careful with oneââ¬â¢s intentions can prevent hindering the friendship by ensuring oneââ¬â¢s actions are the right ones.

Smoke Signals
In the movie, Smoke Signals, two men from the Coeur d Alene Indian Reservation, take a journey to Arizona. The trip turns into a philosophical journey as much as a physical one, encountering odd ball characters and discovering poetic messages at the end of the road. The main characters, Victor Joseph and Thomas Builds-the-Fire have known each other since childhood, they are not exactly friends but share a special link. On July 1976, Victor s father, Arnold Joseph, accidentally sets fire to a house killing everyone inside except manages to save Thomas and his son.?Thomas, who has become a true believer in spirits, narrates the movie. He waits patiently for visions and enjoys stories of both fact and fiction. Yet, he is also a bit of a nerd who spends too much time watching Indians on television and Dances with Wolves over and over again to understand the meaning of being an Indian. Nevertheless, Thomas who was raised by his grandmother continues to worship Arnold even though Arnold le ft the reservation for a life in Phoenix when Thomas and Victor were only 12 years old.Victor seems to be full of hostility toward his father for abandoning him and his mother, Arlene. The boy hood scenes of Victor and Arnold show a man who loves his son dearly but who is also clearly possessed by his own demons. One minute Arnold is happily telling stories to his son, drinking his beer as they drive home, the next he s slapping Victor s head for knocking over the bottle. Victor responds by alternately showing love and rage for his confused and violent father.? Now in his twenties, Victor is a quiet young man, still as a rock.After Arlene receives a call from Phoenix from her ex-husband s friend Suzy Song, informing her that Arnold has passed away, Victor is sent to retrieve the possessions of this man who has caused him such pain. Thomas winds up tagging along for the ride, since he s got the money to get the two of them most the way from Idaho to Arnold s trailer in Arizona.? When they first start their journey they run into two native girls driving backwards in their car. (I feel represents the direction of the Indian culture is heading backward).They pass the local meteorologist / reporter who sits on a deserted intersection broadcasting the rez s happenings for KREZ, the local radio station. The guy is on the top of a van reporting on who goes by and weather they are likely going to be late for work His weather forecasts consist of what he thinks the clouds look like. When the girls go as far as they could with the boys, they ask them if they have they have their passports because it is another world outside the rez.? Along the way, Thomas and Victor teach each other life lessons.Thomas, through his storytelling shows Victor that there s more to life than cynicism and pent-up anger. Victor, in turn, lets Thomas know what it means to be a real Indian. In my favorite scene, Victor has these words of advice, Indians aren t supposed to smile, Thomas, get stoi c. If you don t look mean, white people won t respect you. This shows the inside struggle Victor faces about being an Indian in a white man s world. A few scenes later, when two obnoxious white men sit in their seats, Victor and Thomas don t fight them but retire to the back of the bus.Thomas then states Victor, I guess my new look didn t work, huh? They then engage in warfare by singing a rude anthem devoted to John Wayne s teeth.? The boy s finally get to Arnolds small trailer in Phoenix. They meet Suzy Song, who was a dear friend of Arnold s before he died. According to her they kept each other s secrets . She becomes a catalyst for Victor and no dead father. She tells him the stories of how his father did love him and all the found memories he had. She convinces Victor to go into his trailer to be with him, reluctantly he does.After searching through his father s possessions, Victor finds his father s wallet with a picture. The picture was of Victor and his parents with the word home inscribed in the back. Symbolically, Victor cut his hair as his father did after the fire. This represented the first process of letting go of the anger. ?For Thomas, the trip from Idaho to Arizona means an opportunity to come to grips with his ancestry. For Victor, it s a change to forgive his estranged father in death. For me, it offers the prospect of seeing beyond the stereotypes and realizing that all cultures seem to have the same internal struggles.

A Christmas Carol by Charles Dickens Essay Example for Free
A Christmas Carol by Charles Dickens Essay ? Charles Dickens wrote this novel because he was keenly touched by the lot of poor children in the middle decades of the 19th century. This is the reason which motivated Dickens in doing this, before writing this novel. Before he decided to this he thought of publishing leaflets instead. On the other hand some critics have suggested that Scroogeââ¬â¢s redemption underscores what they see as the conservative individualistic and patriarchal of Dickens Carol Philosophy. Dickens own experiences influenced him a lot in why he wrote this novel and how he cares so much for the children, who were forced to hard labour in the workhouses from such young age as 12. Before the ââ¬Å"New Poor Lawâ⬠was introduced in 1834, a high percentage of young children were forced t work to make sure that them and their families did not die of starvation. There was a well known prison called the ââ¬Å"The Marshelseaâ⬠, it became know in the 19th century around the world through the writing of the English novelist Charles Dickens. His father which was there in 1824 for a debt of ? 40 and 10 shillings however Dickens most traumatic experience was when he was forced to leave school at the young age of 12 to work in a factory instead. Dickens already had ideas of how to use these types of experiences in a novel. Some of the social conditions such as the new poor law have been shown in the ââ¬Å"Christmas Carolâ⬠in this particular quote: ââ¬Å"The Treadmill and the the poor law in full vigour then? â⬠ââ¬Å"Both very busy sirâ⬠` This quote proves to us that Dickens used his novel to express the social conditions through it. Dickens used Scrooge as the main character to show that wealthy people always have a responsibility to help those less fortunate. He clearly shows this view at the end of the novel where he gives a young boy money to buy a turkey for the Crachit family. The family isnââ¬â¢t the richest but has a really warm heart. Crachit tries showing Scrooge that life is not all about money and also that he should try to move on and forget about Bella. Scrooge had a really bad experience when Bella marries someone else because she told him that he cares about money more than her. Scrooge somehow had to overcome this tragic event in his life and since then he has not been able to celebrate a successful eve without thinking of her for even a moment. In much earlier in the novel 3 old men come up to Scrooge asking for money to donate to people for Christmas, however Scrooge is a cold hearted person so instead of donating a few shillings he says ââ¬Å"Bah Humbug. â⬠The main character of ââ¬Å"A Christmas Carolâ⬠is Ebenezer Scrooge. He is an elderly man who lives in London, his sister died leaving a son whose name is Fred. In addition to this Ebenezer has no family. He is a very rich banker. Scrooges clerk Bob Crachit is a middleââ¬âaged man who has six children. Ebenezer is thin and has a slight hunchback, coal grey hair and a wrinkled old face, on which he has reddish eyes, a long pointed nose and thin blue lips as cold as ice. Like his employee Bob is very well dressed. Letââ¬â¢s take a look at Scrooge first, before he got visited by the spirits he was a very stingy person and only cared about his own interests. He couldnââ¬â¢t manage to share his money and was not sensitive to the suffering of others. Ebenezer was even harsh to his employee who never cheated, is reliable, hardworking and had to endure the bad behaviour on him. Bob is satisfied with not owning anything and having no money at all. Bob is satisfied with not owning anything and having no money at all, however the only things that matter for him and make him happy are the small but the most important things in life which is his family. After Scrooge got visited by the ghosts he changed positively and you could even say that was similar to Crachit. Just like he likes Christmas, is a good and open to others, joyous and happy. He even started to share money with the poor and expressed his feelings by helping others. In my opinion Scrooge turned into a better character and I admire his sudden transformation into a better human being. Bob Crachitââ¬â¢s characteristics are that he is poor, has a big family, young and takes care of his close ones, joyful and nice. The crachit family live in a small cosy home but they donââ¬â¢t have enough money to decorate it with luxuries because the most important thing for them is too have enough money for coal/fire so that they would be warm, however most importantly all they want to happen is for Tiny Tim to be a healthy again. The miraculous transformation that Scrooge has made makes us aware that good change is never too late. Also that money cannot buy happiness you just have to share it with other people to make something good of it. A Christmas Carol by Charles Dickens. (2017, Feb 22).

Media Relations of McDonald's Term Paper Example | Topics and Well Written Essays - 750 words
Media Relations of McDonald's - Term Paper Example For several years, McDonald's has been extremely successful for a few distinguished, highly standard conditions. The company with the Golden Arches served a simple menu- hamburgers, French fries, and milkshakes or soft drinks. The food was priced low, its quality was consistent, and it was served speedily from establishments that all looked alike and were extremely clean. However, in recent years, McDonald's has seen its growth rate slow down and its dominant market position slip. There are various reasons for this. The main reason is the numerous accusations made against them by environmentalist and health experts. In 1986 all of this information looked enormously pertinent to the London Green-peace who issued a booklet with the title "What's Wrong With McDonald's" The defamatory pamphlet charged McDonald's for maltreating their employees; alluring their customers with food too high in fat, sugar, and salt, which could lead to cancer and heart disease; causing hunger in the Third World; ruining the rainforest; intentionally revealing their customers to food poisoning; exploiting children through company advertisements; and maltreating animals. Eventually, McDonald's filed a suit against five members of the London Green-peace. The five either had to make an apology or face a long hard trial where they would have to prove every statement in the leaflet to be correct. Three of the five chose to publicly ask for forgiveness. McDonald's collaborated with the EDF (Environmental Defense Fund) to devise a joint waste reduction plan. The result was a highly touted deal that gave McDonald's a reputation as a "socially responsible" business. However, Helen Steel and Dave Morris did not apologize. On one part of the libel case were a $32 billion-a-year corporation and a group of London's most expensive lawyers. On the other side was a pair of activists with a total income of $12,000 a year.Ã Ã

The theory of the marketing channel can be puzzling. At times, it is thought of as the course in use by a product as it progresses from the producer to the consumer or another final user. Several describe it as the route in use by the title to goods as it progresses through different agencies. Still others explain the marketing channel in terms of free coalitions of business enterprises that have come together with the intention of trade.

A marketing channel may be described as the external contactual organization that the management of a business controls in order to attain its distribution objectives. Marketing channel strategy is a key strategic area of marketing management, which fits under the place or distribution variable in the marketing mix (Ken Kaser, 2007).

Los Vendidos Play Analysis
Los Vendidos Play Analysis Beyond an energetic and comical playwright, Luis Valdez Los Vendidos is an accurate reflection of the contemporary American society, focusing on how Mexicans are perceived in this society. The play abounds in stereotypes about Mexicans, which is why the main theme of Los Vendidos is stereotyping. Stereotypes appear in societies because the dominant majority has difficulties in understanding the specificities of particular minorities, as it is the case of the Mexicans, portrayed in Los Vendidos. Nevertheless, stereotypes are nurtured as a modality of keeping minorities socio economically repressed and inferior to the dominant race in the society (Escobar p. 562). By portraying the main stereotypes that are used to refer to Mexicans in United States, such as farm workers, gang members or revolucionarios, Valdez describes the identity crisis experienced by Mexicans, who are trying to resist to the cultural assimilation of becoming Americans. The plot of this play revolves around an intended sale, wherein Miss Jimenez, a secretary of the Presidential administration is on a mission to purchase a Mexican model, in order to appeal to the Mexican electorate. Honest Sancho, the owner of the store that sells Mexican models, introduces to Miss Jimenez three types of Mexicans that she can purchase: the farm worker, the gang member and the revolutionary, exemplifying like this the main stereotypes with which Mexicans are associated in United States. The sole idea that the members of a race can relate with a single model, a robot that is believed to encompass the distinctiveness of an entire race is based on a prejudice (Kassin, Fein Markus p. 155). Another problem that the play raises in relation with the stereotypes created for Mexicans in United States, is that Mexicans themselves came to identify with the stereotypes that the American society created to define them. As such, Honest Sancho admits the main models of stereotyping existent in the American society and promotes them for sale. Although Honest Sancho seems to be interested in his business, exploiting the American culture of stereotyping in order to be profitable, there is, nevertheless, a truth in the fact that Mexicans adhere to the stereotypes created for them and transmit them from a generation to another. The fact that the typical Mexican people living in United States are represented through robots suggests the idea that Mexicans are not seen as humans, but as machines, hence the objectification of this people (Belkin p. 17). Honest Sanchos robots are seemingly created to serve the American society through their hard work, as exemplified by the farm worker, who is built close to the ground, durable, friendly and loves his patroness (Valdez pp. 41-42). On the other hand, the other machines that describe the stereotypical roles of Chicanos in U.S., respectively the gang member and the revolutionary. Yet, the roles of these Mexican models are also well justified, because they serve as criminals that get arrested (Valdez 44). In this sense, they are fulfilling the social role of criminality, serving as the scape goats for the malfunctions of the American society. Through the Mexican robots kept in store to be sold, Valdez demonstrates that the stereotypes have a functional role in soci ety, serving as the servers or the people to be blamed by the dominant race. This reinforces the idea that stereotyping is a form of racism that generates feelings of superiority from the dominant race towards minorities (Escobar 562). Although she is also a representative of the Mexican people in United States, Miss Jimenez identifies more with the dominant Americans than with Chicanos. Just as the white Americans, Miss Jimenez fails to admit the individuality of Mexicans, although she too, is a Mexican American, or una chicana (Valdez 41). On the other hand, she seems to be ignorant of the stereotypes and prejudices that Mexicans experience in United States. As such, when Honest Sancho describes to her that the farm worker is cutting grapes, she responds Oh, I wouldnt know (Valdez 42). This scene raises the question of whether one needs to dissociate of his national identity in order to escape the stereotypes associated with ones race. As such, Miss Jimenez insists that her name should be pronounced using English and not Spanish pronunciation, correcting Honest Sancho and admonishing him for his lack of good English skills, when he addresses her in a Mexican style: My name is Miss JIM-enez. Dont you speak English? Whats wrong with you? (Valdez p. 41). Although the play critiques the American society for its lack of cultural sensitivity to Mexican people, arguing that Americans consider all Mexicans as either farm workers, gang members or revolutionary, Miss Jimenez is the exception that deconstructs this myth. She is a Secretary in the U.S. government, therefore, she is educated, urban, modern, possessing all the features of the casual American. As Belkin (p. 18) observes, she is assimilated. In contrast with her, all the other Mexicans, who fail to become Americans and stick to their Mexican identities are considered stupid, uneducated or violent (Valdez p. 48; Belkin p. 18). Nevertheless, the play transmits mixed impressions about what the American society expects from the Mexicans, which further perpetuates the racial stereotypes directed at this nationality. As such, Miss Jimenez, as the representative of the American government, seeks a Mexican model that is educated, knows good English and a romantic figure to attract the women electorate. These values do not describe Mexican stereotypes, but the product of cultural assimilation (Belkin 18). On the other hand, through the character of Miss Jimenez, the play writer transmits the idea that the American society expects the Mexicans to be cheap. The constant question of Miss Jimenez is he economical (Valdez pp. 42 49) acts like a leitmotif in the play, putting an equal sign between Mexicans and cheap labor force. Cheap labor force is a stereotypical representation of Mexicans, one which is desired and expected by the white Americans, even from the educated and acculturated Mexicans. As such, speaking for the U.S. government, Miss Jimenez seems shocked to hear that the price for the educated Mexican is $ 15,000, asking Fifteen thousand dollars? For a Mexican!!! (Valdez 50). In other words, while the American society expects the Mexicans to become acculturated and integrated, acting and behaving like normal Americans, they still expect them to be cheaper, hence perpetuating the socio economical oppression of this people through prescriptive stereotypes (features widely accepted as defining roles or behaviors) (Corell and Benard 5). What started as a comical play developed complex sociological concepts of assimilation, acculturation or stereotyping. Stereotyping is the central theme of the play and it is vividly represented through all the characters presented in the play (Honest Sancho, Miss Jimenez and the robots). In addition, the social expectations from the Mexicans also perpetuate the stereotypes that keep this people in socio economical oppression to the dominant race in U.S. Las Vendidos teaches audiences about the danger that lies in stereotyping, which can take the form of economic oppression or riots. Stereotyping is more than a form of social discrimination; it is a lifestyle by which the dominant majority and the vulnerable minority live, abiding to the socially shaped misconceptions about how minorities should be or how they should act.

Christianity Essay -- essays research papers
The period from the eighth to the fourteenth century was one of vast reforms, some for the better and some for the worse. During this period in Europe, commonly known as The Middle Ages, economic reforms took place as well as social, political, and religious changes. One common theme throughout The Middle Ages consisted of the relationship between the Church and the State. The Catholic church during this era held a prominent role in society, and it had an abundant amount of power and authority during this time. The Catholic Church exercised its authority in many different stages, in which a response from the people occurred because of the way the Church showed its power. The nature of the Catholic Church began its reform around the time Charlemagne, from 768 to 814, took control. He became a Christian emperor and the first great political leader in Western Europe. His main goal was to promote the Roman Catholic religion throughout all of the world known to man, and to do this Charlemagne coordinated with the pope, which in turn the pope crowned him the holy Roman Emperor. Charlemagne strived to reestablish central authority and revive the culture of the Early Middle Ages, and he succeeded by gaining authority over a large area, including almost all of Western and Central Europe (Charlemagne p.130-131). Charlemagne also made many reforms, mostly Church and educational ones. He first reformed the monasteries by making them Benedictine; he also made sure that the churches were abiding by the rules and not doing anything wrong. Charlemagne designed a system in which four archbishops were set up in four different regions with their headquarters in cities in that particular region. The archbishops appoint bishops authority in their territories. As the Catholic Churchââ¬â¢s authority increases during this time, it also comes with consequences. This system of archbishops and bishops are great for the Church, but Charlemagne uses them as royal agents, which is part of royal policy. Furthermore, Charlemagne makes reforms in education in order to further improve the Church; he sets up a system which strengthens the priesthood by setting up bishop schools. These reforms indicate ââ¬Å"a lack of division between religious and secular affairsâ⬠(Charlemagne p.131). Who really has authority, is it the pope or the king? King Charlemagne did make all of the reforms, but the pop... ... the monarchies of Europe and by the papacy. Considering everything the Catholic Church has gone through , was it successful in the religious mission it set out for. The answer to this question is very opinionated to historians, but I believe the answer is no. Notably during the High Middle Ages in which the crusades occurred, many popes set out into various lands including Byzantium and Islam in order to spread Christianity and stop the popularity of the Islamic religion. Many historians believe that the Crusades contributed to the economic and intellectual development of Europe by reopening Mediterranean east-west trade, but these people are wrong (Cantor p.192). All the Crusades did was stir up religious prejudice and the intolerance of Muslims (Cantor p.193). Although the Christian world learned a great deal from the Muslims, the Crusades were not a part of this occurrence. In addition, the fact that heresy occurred from such groups as the Hussites and the Waldensians further proves that the papacy had problems with people actually turning away from the Catholic Church. How could the Church be successful in its religious mission if groups of people are breaking away from it?

How to Lift Heavy Objects :: essays research papers
How to Lift Heavy Objects It is important to understand how to lift objects correctly. The results of improper handling of materials may result in a painful hernia, a strained or pulled muscle, or a disk lesion. The following rules are to be observed when lifting heavy objects. 1. Do NOT lift an object if it is too heavy or too bulky for good balance. Get help or use mechanical aids such as a dolly or hand truck. 2. Keep the load as close to the centre of your body. The farther the load is from the small of your back, the greater the strain. That is the reason a heavy compact load is easier to lift than a bulky, lighter load - you just cannot get the bulky object close to you. The best way to handle a compact load is to squat down close to the load with one foot alongside it and the other foot behind it. With the feet comfortably spread, you will have better stability with the rear foot in the position for the upward thrust of the lift. 3. Pull the load toward you, then lift it gradually. Avoid quick and jerky motions. Push up on your legs while keeping your back straight. A straight back keeps the spine, back muscles, and other organs of the body in the correct alignment. Tucking in your chin helps to align the spine. No matter what size the load, get as close to it as you can; then get a good grip by using the full palm and extending your fingers and hands around the object. Remember that your fingers have very little power and need the strength of your entire hand. Keep your arms and elbows tucked into the side of your body to help keep the body weight centred. Avoid twisting your body during the lift or while moving the load; change directions by moving your feet. Twisting your body during a lift is one of the most common causes of back injury. 4. Be sure to have a clear vision over the load you are handling. 5. Do NOT change your grip while you are carrying the load. 6. Face the spot in which you intend to set the object down; bend your knees keeping your back as straight as possible and the weight of the object close to your body. 7. Always allow enough room for the load to prevent injury to your toes and fingers.

Evolution vs. Creation Essay -- essays research papers
Donââ¬â¢t Monkey Around in Class à à à à à ââ¬Å"In the beginning, God created the heavens and the earthâ⬠(Gen. 1:1). Words of this nature have been questioned for thousands of yearsââ¬âby naturalists, materialists, humanists, etc.ââ¬âand, in more recent times, have led to court cases, heated arguments, and public debates. The major debate intended to be covered in this piece is that of whether or not evolution should be taught in classrooms. Also, if it is to be taught, should it be taught as fact or theory? It is also intended to present enough evidence to disprove evolution altogether and, as a result, make it much less than a theory, but actually the vain opinions of a man who chose not to accept the truth. à à à à à The entire point of this essay is to breakdown the theory of evolution, invalidate its scientific reliability, and support the necessity of showing its errors and inaccuracies in classroom textbooks side-by-side with creationism. To date, evolution is being taught in public schools as the only theory of origins. Creationism must be included as the only alternative and evolution discredited because of its invalidity. On the other hand, Steve Edinger, a biologist at Ohio University, warned members of the House Education Committee about presenting alternative evidence against evolution, saying it ââ¬Å"was not scientificâ⬠and disservices the students. He continues, ââ¬Å"One would wonder what would happen if a teacher spent half a period explai...

ââ¬Åthe Effects of Diversity on Business Performance: Report of the Diversity Research Networkââ¬Â
Crimson Miller MGT 492 Dr. Turnipseed February 19th, 2010 ââ¬Å"The Effects of Diversity on Business Performance: Report of the Diversity Research Networkâ⬠Article Critique #1 In this article the Business Opportunities for Leadership Diversity (BOLD), The Alfred P. Sloan Foundation, and the Society of Human Resource Management (SHRM) Foundation came together to examine the effects diversity has on a business and the businessââ¬â¢s performance. I agree with the article in that diversity can have a positive and/or negative effect on businesses and their performances. In many ways diversity can be a positive influence on companies and company performances because diversity allows for creativity, challenging othersââ¬â¢ ideas, and avoidance of ââ¬Å"group thinkâ⬠. Diversity in business can allow for a wide range of competitive moves from new ideas and differences in cultures. The better the range of knowledge and skill the more innovative and creative employees typically are in organizations. On the other hand diversity can be a major negative effect on business in that it can cause barriers to communication between employees. Employees that cannot communicate with one another do not work well together; many times become confrontational with each other, and many times are not working towards the same goals because of misperceptions. There may be a language barrier, a culture barrier, a religion issue, or even a knowledge or skill difference that makes working as a team less successful. The sample the organizations were able to obtain in the study, used as a base for this report, was a small sample size but I think that the study was very conclusive. In most situations people from a different background will bring new ideas and compete with each other to create a competitive advantage. Yet, if you put a group of people together that do not understand one another the communication will be difficult which may lead to confusion, frustration, or no communication at all. In conclusion I believe the findings of this study were very accurate even in a much larger scale then have been presented.

A review of recent UK Serious Case Reviews relating to vulnerable adults Essay
Serious Case Reviews (SCRs) concerning vulnerable adults have been laid out to assess the manner in which experts and organizations operated jointly to protect a susceptible adult or have an effect after harm or demise of a susceptible adult in cases of interests to do with organizationââ¬â¢s activities or operations. There lacks a national network in the UK for their collation and psychoanalysis (Manthorpe & Martineau, 2010). This review of recent SCRs in the United Kingdom employs three themes that encompass staff affiliations; family and professions; life history and chronology with the intention of extracting substance appropriate to social work strategy and performance. SCRs with respect to susceptible adults and questions carried out UK adult protection or defense boards at regional position after the occurrence of harm or demise had little or no scrutiny (Brown, 2009). This paper reflects on the role and influence of serious case reviews in safeguarding vulnerable adults. S uggestions on Serious Case Reviews are offered in line with the perspective of the recent review of the vulnerable adult protection in the UK that obtained demands for the operations of Serious Case Reviews to be more constant and for teachings obtained to be assessed and more broadly passed amid social employees, other experts, regulators, and stakeholders. During a period when the UK government declared policies for Serious Case Reviews for adults to shift to a legal foundation, this study focuses on their prospective as knowledge materials, but also on their role and impact. Information collection à à à à à à à The results applied in this study shape a section of a larger research that constituted an analysis of some Serious Case Reviews implemented in the United Kingdom from the time of the emergence of In Safe Hands and No Secrets. Moreover, interviews through cell phones with some experts knowledgeable in such reviews, and study of some Serious Case Review reports played a significant role in this study (Manthorpe & Martineau, 2010). Complete reports of Serious Case Reviews are not easily accessible online or publicly and thus, in the aforementioned reviews, Safeguarding Adults Coordinators (earlier referred to as Adult Protection Coordinators) were called forth to provide Serious Case Review reports that their Board members had earlier commissioned. The Serious Case Review reports differed in volume from 8 to 48 pages. In this study, the reports were reviewed in terms of: â⬠Contemplations on Serious Case Reviews; â⬠Methodology or progression; â⬠Outlay; â⬠Rationale; â⬠Reexamination/action plan; â⬠Review workforce; â⬠Teachings/recommendations; â⬠Threshold of Serious Case Review (if this was particularly reflected on), the rationale behind a Serious Case Review being felt as suitable (Aylett, 2009); â⬠Timescale; â⬠Type of Abuse (encompassing also disregard) using the groups delineated in No Secrets; â⬠Underlying principle for Serious Case Review; information concerning the victims, averred abusers and situations (Aylett, 2008). Because this review focused on learning if the reports clearly handled a number of these aspects thus permitting for assessment of the intelligibility and rigidity of the practice, this review applied full reports. Moreover, there exists an appealing balance in a question involving the major narrative, defining the occurrence and its forerunners, and the bureaucratic nature of the proposals (Benbow, 2008). Findings à à à à à à à The ages of the vulnerable people that were affected or died were reported in age groups while tribe was not reported to sustain strict anonymity. Attributable to the lack of lawful or other fortitudes in a lot of reports, this study refers to averred victims and averred abusers. Some of the articles applied in this research entailed death and proof of disregard or abuse (in case that such abandonment or abuse was evidently contributory to death or not). Other articles entailed assertions of abandonment or mistreatment occurring at the averred victimââ¬â¢s residence attributable to relatives or people given the responsibility of providing care (Cambridge & Parkes, 2006). The rest entailed claims of sexual indignation, abandonment, or abuse with harm nearly causing death, general institutional abandonment, or maltreatment that was caused by pitiable attention and healthcare practices. Purpose à à à à à à à The reports employed were generally clear concerning the rationale of the Serious Case Review that had been carried out, focusing on viewing this as a way to encourage multi-organization operation and lesson knowledge. This, from a report regarding the demise of a woman aged over 90 years after clearly obstreperous behavior of a relative in the countenance of suggestion that the woman ought to be admitted in a health care facility, is practically distinctive. The reason behind this review is to safeguard susceptible people by concentrating on teachings obtained from the cases and giving suggestions with an intention of curbing similar calamity through intensifying and bettering multi-organization processes and deals. The people carrying out Serious Case Reviews excellently comprehend this form of conceptualization of rationale concerning the notion behind them (Cambridge, Beadle-Brown, Milne, Mansell, & Whelton, 2011). Some local authorities do not have Serious Case Review procedures where to base reviews but adhere to the Mental Capacity Act 2005 whose main objective is to offer a legal structure for conduct and judgment making in aid of adults that do not have the capability to make some choices by themselves. The purpose of this review is: To gain knowledge from experience To better future performance by operating on the learning To enhance multi-organization operation To review protection adults practices This purpose of this review is not concerning blame allotment. In case personal matters come about from any Serious Case Review, they ought to be administered by every organization in accordance with their normal practices. Threshold à à à à à à à In cases where death has occurred in conjunction with proof or suspicion of abandonment or mistreatment, such cases ought to at all times lead to Serious Case Review. Where there at one time existed potentially acute injury because of possible maltreatment or abandonment and the instance or occurrence creates issues concerning the manner in which local services and experts have operated jointly, then a Serious Case Review ought to be regarded. Similar standards are relevant where mistreatment or abandonment has occurred, in an individualââ¬â¢s residence or care and healthcare setting, or where numerous abusers are probably engaged (Cambridge et al., 2011). In an instance that perhaps ended in death of an elderly woman, the details were identified as lying in the Safeguarding Adult Boardââ¬â¢s description of significance on grounds of the severe nature of abandonment and disregard she had encountered. This encompassed occurrences of mistreatment, anyone that was severe enough to lead to a referral to adult protection care in the regional authority, but encountered collective abandonment. Nevertheless, it was outstandingly exceptional for the reports to regard the concern of threshold explicitly thus complicating the knowledge of the rationale for carrying out a Serious Case Review (Cambridge & Parkes, 2006). In simple terms, we fail to gain knowledge of the description of the seriousness being used for a Serious Case Review, or the person that has approved the Serious Case Review as having met its threshold (Cambridge & Parkes, 2006). Furthermore, one of the Serious Case Reviews reviewed, embarked on into an occurrence where demise or severe injury never happened, seemed to create some extremely helpful study for broad extents of organizations and recommends that a different threshold could be a system breakdown. The set back of this review was in the investigation and reporting on the conditions that brought about the letdown of care provision that led to the woman that had a learning disability being disregarded the entire night on a transport bus. Teaching and recommendations from Serious Case Reviews à à à à à à à The progression of gaining knowledge, the main rationale of Serious Case Reviews, perpetually leads to recommendations. Most of the Serious Case Reviews that were reviewed recognized discrepancies in inter-organization communication, the precise nature of the discrepancy relying, obviously, on the conditions (Aylett, 2009). The reports segregate the poor affiliations involving, for instance, care personnel, police, caregivers (relatives or physicians), the hospital workforce, and the facilities of adult protection in the regional authority. Outstandingly, some of the reports state on a deficiency of intelligibility as to lead organization, a function the regional authority was anticipated to carry out under No Secrets and that studies recommend had been identified and decided. Devoid of the organizations having a clear depiction, the failure to examine appropriately the threats to susceptible adults or that at hand in a care setting turned out to be more comprehensible following this review. This was pooled with a need for insight concerning adult protection measures, affirming a requirement for training or knowledge amid social and medical care personnel. References Aylett, J. (2008).

Eliade on Baptism
Renate Rodila Professor Nick Newell Rels 2001 17 September 2012 Eliade on Baptism Eliade believes in a sacred space that is connected to the creation of the cosmos from chaos. Through these beliefs Eliade would see baptism as a ritual symbolizing the original act of creation by God. Eliade claims that for religious man and non-religious man a sacred space exists. For religious man the sacred space is not homogenous and divided between the real existing space and the entire formless expanse surrounding it (Eliade 20).For non-religious man, places such as a manââ¬â¢s birthplace can be considered unique and sacred to them (Eliade 24). Religious man separates space between cosmos and chaos. The cosmos is the inhabited world and the chaos is the unknown space outside the world (Eliade 29). Eliade then describes the axis mundi as a vertical feature seen as the center of the world. This center is labeled as a pole, pillar or tree that links the heaven, the earth, and the underworld (Elia de 36).The imago mundi is defined as the cosmos on the ground divided into four regions with the axis mundi as the central point (Eliade 45). The religious man wants to be in a place closest to the gods and can do this by physically living in a location near the axis mundi or by experiencing the cosmos as it was first created. In the book of Matthew and Romans the use of baptism in the Christian world is explained. Matthew 3 tells the story of how baptism started with Jesus going to the Jordan to be baptized by John the Baptist.The moment Jesus was baptized the heavens opened up and he saw a dove as the spirit of god (Bible, Matthew 3:16). He also heard a voice from heaven saying, ââ¬Å"This is my Son, the Beloved, with whom I am well pleasedâ⬠(Bible, Matthew 3:17). Eliade would refer to the Jordan River in Jerusalem as a sacred space for the Christian community. The heavens opening at this spot makes it an axis mundi because it is a place where the communication from earth t o the heavens was exposed.Eliade acknowledges in his writing that Jerusalem is a sacred and holy place in the Judaeo- Christian Traditions (Eliade 44-45). This is the location where Jesus was baptized because of how sacred it was there. In Romans 6 baptism is told to be a way that man can be reborn into a new life free of sin. Baptism make the man become one with the body of Christ and through him become alive to god (Bible, Romans 6:10-11). Then back to Matthew in chapter 28 Jesus told his disciples to baptize people in the name of the Father, the Son, and of the Holy Spirit.Jesus can also be considered an axis mundi because he is the connection to the cosmic levels. So by being baptized and becoming one with Jesus a person is able to get closer to God. Being baptized serves as a symbol of the rebirth of the world. Eliade says, ââ¬Å"The experience of sacred time will make it possible for religious man periodically to experience the cosmos as it wasâ⬠¦at the mythical moment of creationâ⬠(Eliade 65). Man needs to experience the creation of the cosmos and for Christians that is through baptism.When someone is baptized that person is submerged in water and the taken back out. The water can be seen as the formless expanse of chaos and emergence from water symbolized creation and birth, whereas on the other hand, immersion in water meant the loss of form and symbolized a return to the situation prior to creation, and death prior to rebirth. To sum it up Eliade would consider the aquatic symbolism of baptism as a way to get closer to God and spiritually reliving the creation of the cosmos.

Assesment 6 Practical Team Sport
BTEC SubsidiaryExtended Diploma In Sport QCF Level 3 Unit 8: Practical Sport (PT) Unit 22: Rules, Regulations and Officiating in Sport (R&R) Assessment 6 of 8 P1 Skills and techniques- Passing: the skill off passing is used when a player on the same team is giving the ball to another member, this is called passing and this is used to spread the play across the line of attack as the ball in tag rugby cannot be passed forward so generally the ball will be thrown sideways or backwards using the following technique.When the player feels that it is right they will look for a pass by doing this there head position will be looking to where they plan on the ball reaching and this is typically to the midriff of a player on their team so to perform this skill they will have their feet shoulder width apart so that they have balance but also they will have the ball in both hands so that they do not drop it when using the passing action which is having both hands either side of the ball bringing the ball back to create momentum and power and then bring it towards their target and releasing giving the force that is required for it to reach their team mate.Catching: This skill is when you are receiving a pass as you will have to catch the ball and to do this to make your teams play fluent and quick you must have a good technique on how to catch the ball.To have a good technique on catching the ball you must make sure your hands are clear and visible for your teammate to see that you are ready for the ball but then when the ball is heading in your direction you must make sure that your feet are shoulders width apart and that you have a solid base and you are balanced then make sure your hands are close to your chest so that if you happen to miss the ball it will rebound off your chest and will be easier to catch , before catching the ball your head and eyes must be looking at the irection of the ball so that you are ready then when successfully catching the ball look for optio n on whether to pass it on or make a run forwards. Intercepting: The skill of intercepting is used when you prevent the oppositionââ¬â¢s team from making a pass and you catch it which then converts possession into your teams favour.The technique of this skill is identifying where the ball is going to go and getting your body position correct to quickly react and catch it before a player on their team does for example if you are about to go in for an interception you will need to keep eyes on the ball and make sure all your body is in line with the ball including your hands so that you can grasp it in mid-flight. After you have caught the ball there will usually be a gap in their defence so as soon as you catch it there will be the opportunity to run for the score zone.Blocking: This is a skill used again for preventing the opposition from retaining the ball and the technique for this is to get any body part in the way of the balls intended destination. The technique to doing this is to make your body as big as possible with the biggest surface area as possible. To do this you will need to stretch out every limb possible and direct them in the way that the ball is heading so that you can block it. Tactics: on1 defending: This is when your team is the defending team and every person on your team has a person to mark on their team and it is your job to mark them so within tag rugby you would be lined up in your defensive line opposite the person you will be marking, a good point to this is that everyone on their team will be marked however if the person you are marking gets passed you then there is very little cover to prevent them from scoring a try. on 1: This is a tactic used when there is a specifically good player on the oppositions team and it is used by 2 players marking the 1 player that is dangerous to their team and it is there job to mark and defend against this one player, an advantage of this is that it may prevent that one player from scoring how ever because two people are marking 1 player it will leave a player on the other team without someone marking them so it could expose their defence.Zonal defending: this is where the defending team do not mark a person instead they mark zones so for example within tag rugby there would be teammates marking the middle sections and wide sections off the pitch and it is their responsibility to make sure that no one gets past them in that area however this can be quite a hard tactic to implement as everyone in the team needs to be disciplined else gaps would open up in the defence leading to opportunities for the attacking team to score.Half court: This tactic is again one that you would use for defending and this is where your team will only defend half the pitch so when the other team has it in there half they will not pressure them and let them have the ball but then as soon as the ball comes into the defensive half there will be high pressure on the ball carriers and players around them to try and gain possession back and limit the amount of chances the team will get, However leaving the team with this amount of space gives them time to build up pace which could mean that the defending team may not be able to catch the attacking team.

They enable normal bowel movements and decrease the risks of constipation, colon cancer and hemorrhoids. They increase the excretion of cholesterol thus minimizing risks of heart disease and obesity. Vitamins are classified as either fat-soluble or water-soluble vitamins. Water soluble vitamins are not stored in the body. After they are ingested they have the ability to dissolve in water. They are then taken in the blood stream. The body is able to incorporate the amount it requires at the time and the excess is excreted in urine. Water soluble vitamins are all vitamins B and Vitamin C. they can be obtained from grains, vegetables and fruits. Fat soluble vitamins are vitamins that are stored in the body. After ingestion they are dissolved in fat. After ingestion the body uses the required vitamins and the rest is stored and used when required in future. The excess is excreted as stool. The main sources of fat soluble vitamins are oily fish, liver, animal fats, butter, vegetable oil and dairy products. In the body, 45% to 65% of the total calories are carbohydrates. A daily caloric level should be maintained should be maintained at a daily concentration of 1800 calories. This translated to 202-292 grams of carbohydrates daily.

To what extent is an individual's vote the result of a multiplicity of Coursework
To what extent is an individual's vote the result of a multiplicity of factors - Coursework Example The political campaigns that are conducted by the different parties during the electioneering period also have their stake in influencing how an individual will cast their vote. It is clear that the voting process must have evolved from when people were voting according to class up to the place where voting is purely based on personal judgment and assessment of the partyââ¬â¢s policies and the leader. In doing this, will trace the history of voting in Britain. It is going to cover the alignment era of 1940s to 1970s, giving a keen look at how electioneering activities were ran during that period. The essay will also examine the de-alignment era that began from the 1070s onwards, proceeding the alignment era (Denver, 2007 P. 22). The conclusion of the paper will an analysis of the factors that influence voting in the modern day, and specifically look at some recent elections that were conducted in Britain. During this period, voting in the UK was greatly influenced by such factors as social class, family, local community, gender, age, ethnicity, region and religion (Persson, 2000 P. 54). The era between 1940- 1970 can be referred to one characterized by party identification and class voting. There were mainly two major parties that dominated the party system at that time. These were the Conservative and the Labor Parties. There patterns of voting was relatively stable as there was minimum switching of political allegiance (Weibull, 1987 P. 52 ). The people were not very much inquisitive and they went by the current wave of their fellow mates in the social class. The stability could have been attributed to the image that the voters attached to the party of their choice rather than the policies which it upheld. The affiliates cared really less about the policies. Party identification was mainly obtained from social class, parental political party adherence, and the nature of local commu nity, the region that one

Max Weber the sociologist Research Paper Example | Topics and Well Written Essays - 2250 words
Max Weber the sociologist - Research Paper Example His theories broke new ground, proposing that interpretive, non-empirical evidence can be used to analyze and understand the intentions and actions of individuals within socio-economic groups. Weberââ¬â¢s works put into perspective the effect of culture and religion on economics. Placed within a historical perspective, Weberââ¬â¢s work was bold for the time in that it refutes the notion that there can be a quantifiable gauge for the study of social dynamics. Observation and analysis, skills that served Weber well during his esteemed career, were part of a legacy of academic achievement, passed on to him by his accomplished parents. Weber: A brief biography Born into an affluent family, Weberââ¬â¢s father was trained as an attorney, held a prominent position in the civil service and was a member of the National Liberal Party. Max Weber, Sr.ââ¬â¢s involvement in public life exposed his son to a wealth of socio-political ideas, the familyââ¬â¢s home being something of a g athering place for many leading intellectuals of the period. The younger Weber thrived in this atmosphere, which inspired him to take up Goethe, whom he read voraciously from a young age as well as many other volumes of classical works (Ringer, 2004). Law school and a brief stint in the military during World War I were followed by the beginnings of a legal career, which further whetted his appetite for research and theory. The early stages of his professional life were marked by social and economic studies inspired by a growing Max Weber 4 progressive movement, which Weber joined in 1888 as a member of the Verein fur Sozialpolitik, a professional association for economists. ââ¬Å"What united the members of the Verein was a belief that reforms were urgently needed in Germanyâ⬠(Swedberg & Agevall, 2005). The Verein proved to be a stepping stone for Weber, who earned notice for his report on the displacement of workers in East Prussia by Polish emigres (Kim, 2007). Appointments to Freiburg, then Heidelberg University followed. It was at Heidelberg that Weberââ¬â¢s brilliance attracted the attention of other intellectuals, writers and scholars in the charged academic atmosphere of the famous university town. Germany of the late-19th century was a brash new nation, one gripped by hubris and the aggressive policies of the Prussian political ascendancy. The nationââ¬â¢s burgeoning self-confidence gripped many in the intellectual class, including some of Weberââ¬â¢s contemporaries. Refusing to be swept up, Weber remained true to his progressive convictions, venting his feelings about Germanyââ¬â¢s increasing predilection for saber rattling. ââ¬Å"(Weber) also wrote passionate polemics in behalf of parliamentary reform and against the annexationist hysteria that seized many of his colleaguesâ⬠¦Ã¢â¬ (Ringer, 2004). After his fatherââ¬â¢s death in 1896, Weberââ¬â¢s unresolved, stormy relationship with his parent contributed to a nervous b reakdown, which so debilitated Weber that he was eventually forced to resign from his teaching post and to suspend all scholarly activities. Ironically, Weberââ¬â¢s condition, which led to an abrupt and radical change in his professional life, brought about an intellectual change of direction and priority that would round out his personal philosophy and make him a pioneer in the developing field of social science (Kim, 2007). The resultant study

Managing New Media Projects Essay Example | Topics and Well Written Essays - 2500 words
Managing New Media Projects - Essay Example It has been contended that the surfacing of novel, digital technologies hinted a fundamental shift of who is in control of information, experience and resources (Croteau and Hoynes 2003, p. 322). Likewise, it was inferred that new media will: 1) change the implication of geographic distance; 2) facilitate massive swelling in the volume of communication; 3) offer prospects of increased speed in communication; 4) present greater chances of interactive communication; and 5) permit structures of communication that were formerly separate to be integrated and get linked (Croteau and Hoynes 2003, p. 303). Accordingly, there are discussions between many academics indicating that the new media, predominantly the internet, offer the prospects for a democratic postmodern public sphere, where citizens can contribute and involve themselves in educated, non-hierarchical deliberations relevant to their social structures. On the other hand, those opposing the constructive assessments of the probable social effects of new media have put forward the notion that the switch to new media has seen a handful of influential and potent global telecommunications organisations that have achieved a level of large-scale influence which was previously inconceivable. Contemporary inputs to the field have underscored the constructive and off-putting prospects and tangible propositions of new media technologies, signifying that a few of the earlier works on new media studies were guilty of technological "determinism," wherein the upshots of media were determined by the technology itself, rather than mapping out the intricate social networks that manage the progress, financial support, execution and future advance of any technology (Lister et al 2003; Flew 2002, p. 13; Durham and Kellner 2001; Marmura 2008, p. 247). -- P R O D U C T I O N P L A N - (GreensForYou) Project Analysis An English website for a new chain of organic food stores based in London, GreensForYou targets male and female customers aged 25-45. It seeks to disseminate information to the public basic details regarding the stores' location, wide-ranging use of images showing the origin of the food being sold, the ethical strategies used in food production, its home delivery services and most especially the project's campaigns supporting fair trade. Likewise, it has an e-commerce component, a flash mini-game about organic food, an interactive quiz about the benefits of fair trade and an educational segment featuring interactive activities and educational content for teenagers aimed to instruct them on the essentials of organic food. One critical issue in this undertaking is with regards to copyright clearance and intellectual property. Unless all of the content used in the GreensForYou project is originally created by the production team, the group really needs the suitable copyright clearances and even if site owner is dealing with content created by others or by its very own project team, the new intellectual property the site has created likewise needs to be protected; more so in the case of audio or music, the rights of the performer, record producer and copyright holder, have to be cleared (CHIN 2002, p. 42). With this issue are some limitations that need to be appraised. The growing accessibility and dropping cost of bandwidth implies that more and more
European Central Bank Essay Example | Topics and Well Written Essays - 1000 words
European Central Bank - Essay Example Inflation is a rise in the price of goods and services within an economy which results in a decline in the purchasing power of every subsequent unit of currency and this causes a loss in the real value of exchange within an economy. The main measure of inflation is the Consumer Price Index which provides an indication of the price level of consumer goods and services which are purchased by households, business firms, the government as well as the rest of the world (in case of an open economy). The CPI in the United States is defined by the Bureau of Labor Statistics as ââ¬Å"a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services.â⬠As per the current happenings within the German economy, the prices of goods and services naturally saw a hike due to the holiday season; this period mostly witnesses an increase in demand of goods and services which is met by an almost equivalent amount of supply. In order t o understand the price indices of an economy, the CPI can be understood because it helps to measure the level of increase in the prices of goods and services within the German economy, which is now being maintained at a 2.3% increase. However, this is better than the 3% that it had risen to. Most governments, especially in the European zone, had been able to recover well from the financial crisis that took place world over in 2008-2009 but the repercussions of that are lingering on as inflation in the same economies.... German consumer prices nonetheless, harmonised to compare with other European Union countries, showed a rise of 2.4 percent on the year in December, down from 2.8 percent in the previous month. The German economy took to cutting down interest rates, a primary step undertaken by any economy in the world in order to slow down the persisting amount of inflation. The resulting inflation indicates the rise in general prices for typical German consumers, and consumers investing within the economy of Germany. This entire process works according to the demand pull theory according to which interest rates within the economy need to be cut down in order to counter inflation. If the government is able to increase the rates of interest being charged on commodities being sold within the economy, then it will have a way of getting back financial resources. Low interest rates within the German economy have put more borrowing power in the hands of the consumers. Interest rates refer to the rates at which a borrower is able to borrow money in order to have greater purchasing ability. Since loans and smaller debts can be taken from the European Central Bank at lower rates, consumers have been able to increase their purchasing powers and have been thus causing the economy to slow down considerably. Due to increased spending by the consumers, the economy has witnessed a growth and expansion which has almost led in the demand outpacing the supply. The holiday season witnesses a peak in consumer shopping and indulging in goods and services more than any other period because of increased and extremely affordable tours and travels. If the demand rises faster than the supply within the economy

Project Management Principles Essay Example | Topics and Well Written Essays - 1000 words
Project Management Principles - Essay Example Once the purpose has been stated, the planning stage can commence. An important part of the planning is to define what is required for the problem to be solved. These requirements should be clearly stated and communicated to employees in such a fashion that everyone is onboard with the plan of action. The next stage of project management is prioritizing. This is an often unnoticed stage in the process because it does not openly contribute to the solution. Actually, prioritizing targets is a very sensible thing to do because there may not be enough time or resources available to complete everything to an acceptable standard. It should be expected that the project may not be completed within the budgeted timeframe, so alternative plans need to be prepared just in case the unthinkable happens. Generally, organizations should plan to take more time than is needed just to be safe. In order to help accomplish the goals and objectives of a project management plan, a project manager needs to be appointed as the leader. This person is vital because they will determine the potential success or failure of the project. This person holds a critical role within the organization because his responsibility is to deal with any obstacles that may crop up. Other than this position, there should also be a project sponsor. The project sponsor is the person who will receive a benefit from the project. There are three people that should report to the project sponsor: application architects, technical architects, and data architects. Apart from these people, there should also be analysts, designers, modelers, and developers. It is preferred that experts are given these positions, but trainees are also acceptable. If this happens to be the case, then there should be no more than two trainees to one expert. Once the project has begun, senior management will require an approximate estimate of how long each stage of the project will take. There are three methods that are commonly used wit hin organizations for giving estimations: top-down, parametric, and bottom-up. The first method is not very accurate, but can be useful in giving a rough estimate at the start of the project management process. The parametric system is slightly more accurate in that this process sums the number of work units by the time it takes to complete one work unit. This technique is generally useful when a certain task has previously been completed and thus the new task can be estimated based on that fact. Lastly, the bottom-up method is the most accurate, but every single detail is required to give an approximation on how long a task will take. In terms of issues that may come up in project management, I feel that lack of clarity plays a huge part in the project not going to plan. At the beginning of the project, if every step is not laid out, then it will be difficult to determine which processes have been completed. A written agreement should be made between the project manager, the projec t customer, and the project sponsor. This document should identify the projectââ¬â¢s objective and how this objective will be met. It may be that the project needs to change slightly once the process has begun. If this is the case, then the change management process needs to be implemented so changes can be made when needed. This leads to the next issue with project managementââ¬âshifting managerial priorities. The business environment is always

International Market Expansion Essay Example | Topics and Well Written Essays - 1500 words
International Market Expansion - Essay Example Consider if the return in Vietnam pillories is 10% of the total investment but on the other hand if currency that is Vietnamââ¬â¢s dong depreciates also by 10% then the gain to corporation will be nothing, with the same token if currency depreciates by more than 10% the Pfizer pharmaceutical will face loss and if their currency appreciates by 10% or more the Pfizer pharmaceutical can also yield abnormal profit. So, there exists a risk of foreign currency in case of business exposure to Vietnam. Though currency risk prevails in business exposure but companies can overcome this currency risk and can protect their profit even in crisis too. Following are some of the possible risk aversion strategies for business expansion. The first and foremost solution is to actually measure the volume of risk through analysing the companyââ¬â¢s exchange flows. In the exchange process when currency transaction takes place it is advised to negotiate payment of currency in your own local currency in this case that is US dollar. Trading in your local currency will reduce the risk of conversion rates in the form of exchange rate shocks besides the expected fluctuations will be bore by the other party while your returns will not be affected by this risk. When companies are experiencing foreign exposure they should keep an eye on the changing currency rates and whenever possible they should take optimum advantage of the current rate. In reducing currency exchange rates, companies should keep dates for payments close to the signing of the contract date, this will reduce risk of fluctuations. Keeping certain amount of deposits as security with a defined ratio of contract size can also help minimizing risks. With the help of brokers and foreign exchange solutions companies can lock in future exchange rates and buy contracts with future perceptions but there is no exact solution to the failure of this future exchange rate so, instead of open period, short period for bid and contract s will limit the risk of currency exposure. Companies should double check foreign exchange rates when they are setting up prices because selling product in a foreign country mean payments will be collected in foreign currency, but if the exchange rate is low with lower prices the company will end up in loss. So, setting up prices is also a key factor in reducing loss.(Prinzel, 2012) The solution can also be to diversify the exchange rate which will also reduce risks. Since Pfizer pharmaceuticals has its business exposures in almost 42 countries, this diversification can help reducing currency exchange risks as if Vietnami dong depreciates, exchange rate in other country may appreciate so, Pfizer pharmaceutical already entails this solution which will further help reducing risks. Pfizer can also neutralize its risks through managing its dealings as currency in Vietnam depreciates, it will help if Pfizer purchase its raw material from foreign supplier who are dealing in Vietnami dong that will make product cheaper as payment is made in dollars. On the other hand it will neutralize the risk of foreign currency exposure too.(Alan C. Shapiro, 1982) 2. Evaluate the basic functions of the international banking system and

Chitin: Applications, Composition and Properties
Chitin: Applications, Composition and Properties 1. Introduction Chitin, poly (b-(1-4)-N-acetyl-D-glucosamine), is a natural polysaccharide of major importance. It was first discovered by Braconnot (1811), a professor of natural history. He isolated chitin from mushrooms by treating it with warm alkali. Later Odier (1823)Ãâà found chitin while studying beetle cuticles and named chitin after Greek word chiton (tunic, envelope). The silk worm was also discovered as a source of chitin when Lassaigne (1843) isolated it from the Bombyx mori. The monomeric unit of chitin (N-acetyl glucosamine) became known because of the work of Ledderhose in 1878. In the first half of the twentieth century, research on chitin was mostly directed toward the study of its occurrence in living organisms. Finally in 1981 Austin and his coworkers came up with a completed data on the sources of chitin which is widely distributed in marine invertebrates (Figure 1), insects, fungi, and yeast (1981). However, chitin is not present in higher plants and higher animals. Genera lly, the shell of selected crustacean was reported by Knorr (1984) to consist of 30-40% protein, 30-50% calcium carbonate and calcium phosphate, and 20-30% chitin. Chitin is widely available from a variety of source among which, the principal source is shellfish waste such as shrimps, crabs, and crawfish (Allan et al., 1979). It also exists naturally in a few species of fungi. Chitin occurs in nature as ordered crystalline microfibrils forming structural components in the exoskeleton of arthropods or in the cell walls of fungi and yeast. It is also produced by a number of other living organisms in the lower plant and animal kingdoms, serving in many functions where reinforcement and strength are required. (Rinaudo, 2006). The structure of chitin has been described (Fig. 1). In terms of its structure, chitin is associated with proteins and, therefore, high in protein contents. Chitin fibrils are embedded in a matrix of calcium carbonate and protein. The matrix is proteinaceous, where the protein is hardened by a tanning process (Muzzarrelli, 1977). Studies of Ashford et al., (1977) demonstrated that chitin represents 14-27% and 13-15% of the dry weight of shrimp and crab processing wastes, respectively. 2.2. Characteristics and Structure of Chitin Chitin is made up of highly extended hydrogen bonded chain and is semi-crystalline in structure of chitin [Rinaudo (2006) Kurita (2001)]. Chitin is a structural biopolymer, which has a role analogous to that of collagen in the higher animals and cellulose in terrestrial plants [Muzzarelli, (1977) Mayer, (1996)]. Plants produce cellulose in their cell walls and insects and crustaceans produce chitin in their shells (Muzzarelli, 1986). Cellulose and chitin are, thus, two important and structurally related polysaccharides that provide structural integrity and protection to plants and animals, respectively [Muzzarelli (1986) and Roberts (1992)]. Chitin occurs in nature as ordered crystalline microfibrils forming structural components in the exoskeleton of arthropods or in the cell walls of fungi and yeast (Raabe 2007). In crustaceans, Chitin polymers tend to form rod like fibrils or crystallites that are balanced by hydrogen bonds formed between the amine and carbonyl groups. X-ray diffraction analysis suggests that chitin is a polymorphic substance that occurs in three different crystalline modifications, termed ÃŽà ±, ß and ÃŽà ³ chitin. They mainly differ in the degree of hydration, in the size of the unit cell and in the number of chitin chains per unit cell [Rudall and Kenchington, (1973) Kramer and Koga, (1986)]. In the ÃŽà ± form, all chains exhibit an anti-parallel orientation; in the ß form the chains are arranged in a parallel manner; in the ÃŽà ³ form sets of two parallel strands alternate with single anti-parallel strands. Chitin is found to occur as fibrous material embedded in a six stranded protein helix [http://meyersgroup.ucsd.edu, 2006]. The polymorphic forms of chitin differ in the packing and polarities of adjacent chains in successive sheets; in the termed ÃŽà ± form, all chains are aligned in a parallel manner, which is not the case in ß form and ÃŽà ³ chitin. The molecular order of chitin depends on the ph ysiological role and tissue characteristics. In both structures, the chitin chains are organized in sheets where they are tightly held by a number of intra-sheet hydrogen bonds with the ß- and ÃŽà ³ chains packed in antiparallel arrangements Rinaudo. (2008). 2.3. Biodegradation of tiger prawn shell by Lactic acid fermentation for extraction of Chitin Every year tones of sea food waste is dumped onto the shores of the sea and lagoons or in the inner mangrove area surrounding the sea for these are the regions where maximum sea food cultivation is done. These areas are the hub of number of small and large scale seafood industries which deal with culturing and processing of seafood. This huge amount of sea food waste is polluting the surrounding land and water and is depleting the fresh water supply. Dumping of Seafood waste leads to accumulation of sediments causing organic pollution which causes physical disturbance of hydrological regimes resulting in a number of ecological problems which include conversion and degradation of costal ecosystem. ( Mathew and Nair, 2006) The demineralization of crustacean shells have been chemically performed using concentrated acids such as HCl (Whistler et al., 1962), H2SO4 (Peniston and Johnson, 1978), CH3COOH (Bautisa et al., 2000) and HCOOH (Horowitz et al., 1957) by various researchers. However, the chemical methods are expensive and detrimental to the environment leading to effluent problems [Shirai (2001) and Fagberno (1996)]. The Traditional method of chitin preparation from crustacean waste involving the use of alkalis and acids for demineralization, make the method ecologically harsh and a cause of pollution (Rao et al., 2000) It also reduces the chitin quality to certain extent (Simpson et al. 1994; Healy et al., 1994) mostly such processes depolymerising chitin to a higher extent leading to the formation of a deacetylated form of chitin called chitosan. Biotechnological process of lactic acid fermentation of crustacean shell waste is a powerful tool to overcome the environmental problems. Fermentation of crustacean shells using lactic acid bacteria is also an attractive method which lowers the pH of the medium and facilitates the demineralization of minerals and the hydrolysis of proteins while leaving the associated chitin intact. Thus this process also helps in a safe recovery of chitin as the fermented residue. Also, fermentation of crustacean bio waste to recover chitin considerably replaces the expensive and non environmentally friendly chemical process [ Rao et al., (2000), Shirai et al., (2001) and Hall et al., (1992) ]. Lactic acid bacterial fermentation of shrimp waste for chitin recovery was studied with lactose or cassava extract as additional sources of carbohydrate for natural energy (Hall and Silva 1992). Raw heads of Africa river prawn were fermented with Lactobacillus plantarum using cane molasses (Fagbenro 1996). Treatment of minced waste of scampi in the presence of glucose by a culture of Lactobacillus paracasei strain A3 was investigated (Zakaria et al. 1998). The primary object of all these studies was demineralization of the raw materials along with which deproteinisation took place (Shirai et al. 2001). The effectiveness of demineralization was exaggerated by the increasing inoculum amounts supplied. Also, the proportion of glucose was significant for the lactic acid fermentation by the bacterial strain to demineralize the shell wastes (Shirai et al. 2001 and Rao et al. 2002). The demineralized and deproteinized chitin has a light pink color due to the presence of astaxanthin pigment. When bleached product is desired, this pigment can be eliminated by the decolorization using bleaching agents. The resulting chitin is insoluble in most organic solvents; however, its deacetylated derivative chitosan is soluble in some acids. The subsequent conversion of chitin to chitosan is generally achieved by treatment with concentrated sodium hydroxide solution (40-50%) at 100à °C or higher for 30 minutes to remove some or all of the acetyl groups from the polymer (No and Meyers, 1995). Lactic acid bacterial fermentation for demineralization has also been occasionally reported for shrimp waste (Shirai et al. 2001) crayfish exoskeleton (Bautista et al. 2001) and scampi waste (Zakaria et al. 1998). However, demineralization by lactic acid fermentation of tiger prawn shell waste along with the characterization of the resulting chitin has been less studied in relation to glucose concentration and inoculum amount. In the present work, we evaluated the demineralization of tiger prawn shell waste by lactic acid bacterial fermentation with various concentrations of inoculum and glucose and characterize the fermented residue the chitin by powerful techniques such as X-Ray diffraction, FTIR, SEM and TGA. From the literature it is evident that the limitations of the chemical method for the degradation of sea food can be largely overcome by the biological method of demineralization and hence research interest has been shown in recent years in this direction. Lactic acid fermentation of crustaceans shell waste has been reported to be studied as a potential biological method of degradation (P Mathew and KGR. Nair, 2006) 2.4. Factors Affecting Production of Chitin by Lactic Acid Fermentation 2.4.1. Effect of Initial Glucose Concentration and Inoculation Level of Lactic Acid Bacteria on Tiger Prawn Shell Waste Fermentation Amount of starter culture and initial glucose concentration are critical factors in the fermentation of tiger prawn shell waste fermentation. A correct proportion of initial glucose and starter culture concentrations increase the amount of lactic acid produced and thus increased the % demineralization. Glucose is a readily fermentable sugar and hence chosen as the source of carbon for the microbes in most of the studies. Glucose concentration is a highly important parameter of fermentation and hence chitin production. According to Jung et al. (2004) Microbial growth and hence acidification of the broth during fermentation is highly dependent on glucose concentration. Lactobacillus sp. has the potential to produce lactic acid and other organic acids. Using organic acids such as lactic and/or acetic acids for the demineralization process is a promising idea since organic acids in order to produce low cost biomass, purified chitin and reduce the harmful to the environment (Jung et al., 2005,Rao et al., 2000, Sunita et al.,2009). According to Hong et al. (1999) the production of organic acids by the lactic acid bacterium L. plantarum decreased the pH and made the environment selective against spoilage microorganisms. Zakaria et al. (1998) had also reported that the decaying of the raw crustacean waste materials can be controlled through the selection of microorganisms having a high capacity to produce organic acids. Further Shirai et al. (2001) reported that the selection of the correct micro organism is an important factor for the acidification of crab shell waste and for suppressing the growth of spoilage organisms. Cira et al., (2002) reported that lactic acid bacteria fermentation with the 10% inoculums was helpful in attaining a pH of around pH 5 after day 3. On the other hand it was reported by Shirai et al. (2001) that lactic acid fermentation of shrimp wastes which contained 10% glucose and a 5% inoculum of Latobacillus sp. B2 lowered from to pH 4.5. Therefore medium pH likely depends on the content of the energy source such as glucose and sucrose and the other factor least considered but of great importance is the solid to liquid ratio. Lower the solid to liquid ratio higher is the rate of demineralization. As the solid concentration increases the concentration of slurry increases resulting in reduced mass transfer and hence poor demineralization occurs. (Kyung. et al., 2008). The selection of the potential microbe along with the correct proportion of the additional starter is very important for the lactic acid bacterial fermentation to demineralize the raw shell wastes (Shirai et al. 200 1; Rao et al. 2002) along with the correct propotion of solid to liquid ratio (Kyung.et.al. 2008). 2.4.2. Temperature of Fermentation Application of microorganisms or enzymes to extract chitin from marine crustacean wastes is a current research trend for bio-conversion of wastes into useful biomass (Bhaskar et al., 2006). From his study he analyzed that a temperature of 35Ãâà °C resulted in lowest pH conditions of pH 3.7 and highest % demineralization of about 92%. Kyung et al., (2008) reported that a temperature of 30Ãâà °C gave the highest % demineralizatuion. 2.4.3. Particle Size Particle size in chitin productions has sparked controversial reports on its effect on chitin quality. Some agree that small particle size is better than large particle size. According to Bough et al. (1978), smaller particle size (1mm) results in higher demineralization % with a chitin product of both higher viscosity and molecular weight than that of larger particle size (above 2 to 6.4 mm). The larger particle sizes require longer swelling time resulting in a slower deacetylation rate. 2.5. Process Optimization by Taguchi Taguchi method of production optimization is a purely statistical approach to analyze scientific data based on statistical factorials. Taguchi experimental design offers remarkable advantages by examining a group of factors simultaneously and extracting as much quantitative information as can be extracted with a few experimental trials [Stone and Veevers, (1994) and Houng et al., 2006]. But yet only a few reports are available on the application of Taguchis method in the field of biotechnology (Cobb and Clarkson, 1994 and Han et al., 1998). 2.6. Characterization and Physiochemical study of Chitin 2.6.1. X-Ray Diffraction Analysis The crystalline structures of chitin are differently presented according to the raw materials. XRD is low cost and user friendly method to accurately characterize the kind of chitin extracted from a particular species. Chitin has three different crystalline polymorphic forms according to the derived material ÃŽà ± chitin, ÃŽà ² chitin, and ÃŽà ³ chitin. The structures of the ÃŽà ± and ÃŽà ² forms differ only in that the piles of chains are arranged alternately antiparallel in ÃŽà ± chitin, whereas they are all parallel in ÃŽà ² chitin. The structures of ÃŽà ± chitin, ÃŽà ² chitin, Sugiyama et al., (1999) and Syed et al., 1999; have been determined by X-ray diffraction (XRD). According to the crystalline structure of chitin suggested by Rudall (1963) and (1967.) ÃŽà ± chitin has strong intersheet and intrasheet hydrogen bonding,and ÃŽà ² chitin chitin has weak hydrogen bonding by intrasheets. Therefore, in contrast to ÃŽà ± chitin, ÃŽà ² chitin i s characterized by a weak intermolecular force, Lee et al., 1996. Not much information is available regarding the crystalline study of ÃŽà ³ chitin by X ray diffraction technique. The XRD profiles of chitin samples easily help to distinguish the different forms of chitin based on the peaks and crystallinity. It has been found that ÃŽà ± chitin has three to four sharp crystalline reflections at 9.6, 19.6, 21.1, and 23.7Ãâà ° whereas ÃŽà ² chitin , has two broad crystalline reflections at 9.1 and 20.3Ãâà ° within the 2ÃŽà ¸ range of 5-35Ãâà °. These results also support that the crystallinity of ÃŽà ² chitin is less than that of ÃŽà ± chitin because of the parallel structure. ÃŽà ± chitin has a more rigid crystalline structure because of its intersheets and intrasheets, and its structure exists as a stable structure with neither a crystalline phase transition nor thermal decomposition ( Jang et al., 2004). 2.6.2. FTIR Spectrophotometer Measurements Different methods have been used for the purpose of measuring the degree of deacetylation of chitin for eg. the linear potentiometric titration, ninhydrin test, hydrogen bromide titrimetry, near-infrared spectroscopy, nuclear magnetic resonance spectroscopy, infrared spectroscopy, and first derivative UV-spectrophotometry. Among all the tests stated above FTIR is one of the potential methods to determine the degree of deacetylation of the sample. It is far easier yet highly sensitive compared to the other processes. The process of removal of acetyl groups from the molecular chain of chitin is called deacetylation, it leaves behind a high degree chemical reactive amino group (-NH2). Thus the physicochemical properties of chitin highly depend on the degree of deacetylation (DD) hence it determines its appropriate applications. (Khan et al., 2002) Degree of deeacetylation also affects the biodegradability and immunological activity (Tolaimate et al., 2003). The degree of deacetylation c an also be used to differentiate between chitin and chitosan because it helps to know the amount of free amino groups in the polysaccharides. A degree of deacetylation of 75% or above in Chitin is generally known as chitosan (Knaul et al., 1999). 2.6.3. TGA The thermal degradation of chitin or chitosan with a broad range of DD has received little attention (GuinesiCavalheiro, 2006; Kittur, Prashanth, Sankar, Tharanathan, 2002). There are fewer reports on the thermal degradation process of chitin/chitosan and its derivatives than on chemical and enzymatic degradation (De Britto Campana-Filho, 2004; Holme, Foros, Pettersen, Dornish, Smidsrod, 2001; Hong et al., 2007; Neto et al., 2005; Qu, Wirsen, Albertsson, 2000; Wanjin, Cunxin, Donghua,2005). Thus to examine the thermal degradation of chitin with a broad range of DD, thermogravimetric analysis (TGA) is a highly useful technique. It has also been reported that with an increase in the rate of deacetylation the temperature of degradation decreases (Young et al., 2009). 2.7. Application of Chitin Chitin and chitosan has several distinctive biological properties, including biocompatibility and biodegradability, cellularbinding capability, acceleration of wound healing, hemostatic properties, and anti-bacterial properties (Cho, Cho, Chung, Yoo, Ko, 1999; Muzzarelli, 1993; Tomihata Ikada, 1997).Some of the important industrial applications of chitin have been listed below in Table 1.
