Business Law Assignment Example | Topics and Well Written Essays - 2500 words
Business Law - Assignment Example The offeror cannot just cancel an offer once it is made. When an offer is made, the offeree (the one the offer is made to) can decide whether to take it or not within a reasonable timeframe. Since an offer puts some kinds of obligations on the offeror, there is the need to define what constitutes an offer. In this definition, there are some exceptions to the rule. When a person makes an indication that another person can enter negotiations for a contract, this is not an offer, it is an invitation to treat. A typical example of an invitation to treat is the case of the display of goods in a shop window. In Pharmaceutical Society of Great Britain V Boots Cash Chemists (1953) it was held that goods displayed in a shop does not constitute an offer but an invitation to treat. Additionally, the declaration of an intent is not an offer. In Harris V Nickerson (1873), an auctioneer advertised the sale of goods in an auction. However, he refused to hold the auction on the said date. A prospect ive attendant sued for a breach. It was held that the advert was simply a declaration of intent but not an offer. Application In this, the advertisement by Gift House that they have reduced their A1 cameras was not an offer. It can be considered an invitation to treat. ... They are mere invitation to treat and declaration of intent respectively. Due to this, Martin does not have the right to purchase the camera at ?50. Davina Issue Davina gets informed that the A1 Camera (which sells for ?100) goes for ?50 in the shop. The shop also states that if anyone purchases goods worth ?500 by 1st December, there will be a free television. Davina mails an order for the camera and the goods totaling ?500 and indicates she wants the free television on 30th November. Davina receives the goods but finds out that she was charged ?100 for the camera and she did not get the television which was promised. The issue is whether the postal order created a legal contract that gives her rights to the camera at ?100 as well as the television set. Rule In Carlill V Carbolic Smoke Ball (1893), the defendants advertised to pay ?100 to anyone who caught flu after using smoke their smokeballs. Mrs Carlill used the smoke balls but caught flu. She argued that she was entitled to the ?100 promised. It was held that the offer was one that a reasonable person could take seriously. Secondly, the postal rule is established in the case of Adams V Lindsell (1818). It states that acceptance of an offer takes effect once the acceptance letter is posted. Application In this case, Davina saw a catalogue that advertised two things: the sale of a camera at ?50 and an offer of a free TV when a customer shops to the tune of ?500. This is something that the average person could take seriously and follow up. Davina followed up by making an order through post on the 30th of November. This order was a valid claim for the A1 Camera at ?50 and the TV prize since she shopped to the tune of ?500. According to the postal rule, this postage

Information Overload and Intelligence Operations Essay
Information Overload and Intelligence Operations - Essay Example I agree that one of the key areas of definition is the development of the issues that are directly related to intelligence operations. I believe that intelligence collection and analysis operate hand in hand, arguing that too much collection and little analysis would only lead to ineffective intelligence operations, and the opposite has the same result. It is true that the issue of mass data collection and the appropriate measures that can be taken to analyze mass data. The post focuses on the noise created by the mass data collected, when you comment, "â⬠¦ there is difficulty presented within intelligence analysis in the context of mass data collection and the amount of ââ¬Å"noiseâ⬠created by an overwhelming amount of information." Intelligence analysis is more time and resource consuming as compared to data collection as recurrently referenced by the student. However, you ignore assessing the technological innovations created to make an analysis easier, which are less t ime-consuming. Regardless, I agree with the student who argues that the analysis is as equally critical to intelligence operations as collection of appropriate data is. I agree that data analysts are responsible for incorrect information or the incomprehensive information because thorough analysis is rather tasking for analysts. It is good when you introduce the concept of information overload, which is a rather clever approach to address the topic. Information overload has been noted to cause most analysts make poor judgments or ignore a series of vital components of information. You did a great job by going to the extent of showing the worst effects of information overload. According to the post, information overload that overwhelms the analysts poses a critical security threat to the country. ââ¬Å"Our nation becomes less secure because analysts are more indecisive, stressed, and pose ââ¬Å"less effective analysis of decisions." All in all, I agree that the analysis is a mental process and that exhaustion is highly likely to affect the productivity of analysts. I think that this is an exceptional piece.

The History Place Adolf Eichmann | Summary
The History Place Adolf Eichmann | Summary Adolf Eichmann In the following paper, the thesis on ââ¬Å"The History Place Adolf Eichmannâ⬠is ââ¬Å"Eichmann, the man who changed his mind in the treatment of Jews.â⬠It examines the different stages of his participation in the holocaust. Adolf Eichmann was influential in the development of social, political, and economic history during Hitlers rule. The paper will end with a conclusion and some personal observations. Eichmann started out in the bottom-most ranks of the Nazi party as a clerk for the section assigned to investigate prominent Jews. His interest in Jewish culture escalated as he began to study their language, and attend Jewish sections of towns. He became known as the ââ¬Å"Jewish specialist,â⬠(p.2) which gave him the ability to rise in the ranks of the Nazi party. Eichmann, in the beginning, had no intentions to commit genocide of the Jews. Instead, he initially attempted to relocate the Jewish population. Upon being assigned to explore potential ââ¬Å"solutions to the Jewish question,â⬠in 1937, he visited Palestine. His goal was to convince the Arab leaders to allow him an exodus of Jews to the Middle East. However, he was unsuccessful and sent out of the country (p.2). Although it would be horrible to relocate a certain ethnic group, it exemplifies that he did not yet intend for murder to occur. In 1938, during the Nazi occupation of Austria, upon realizing financial gain was possible, he created a ââ¬Å"Central Office for Jewish Emigration,â⬠in Vienna (p.2). This had the purpose of extorting the Jewish peoples wealth for a safe way out of the country. The concept was very successful as tremendous wealth was gained and he established similar offices in Prague and Berlin. He had not yet considered murdering the Jewish people. Instead, he offered a secure way to save their lives in return for their wealth. Eichmann, despite stealing money from Jews, had no obvious intentions of committing genocide. In another attempt to relocate the Jews, in July 1940 Eichmann suggested the ââ¬Å"Madagascar Plan,â⬠(p.2) which involved deporting the Jewish population to Madagascar. However, it was never carried out. The Madagascar plan was his last attempt at Jewish relocation before resorting to the ââ¬Å"Final Solution.â⬠Eichmann did not want to treat Jews in harmful ways. In a way, he was trying protecting them from the Nazi regime. He still thought they had a right to live. However, Eichmann soon began his ascension into murdering the Jews.Ãâà In Poland, Eichmann forced the Jews into labor camps where thousands of Jews were kept in very small areas; such as the Warsaw ghetto in Poland. This resulted in overpopulation and ensuing deaths through disease and starvation (p.2). At this point Eichmanns mindset had changed as he no longer cared about relocating the Jews, instead fixated on liquidating them. More atrocities to the Jews were committed in the Soviet Union. Daily records were taken to see how many Jews had been slaughtered. Eventually, competitions arose to find out which of the four groups Eichmann controlled had the highest death rates (p.2). Eichmann became more ruthless, making genocide into a contest. He was unremorseful for his actions, turning it into a game. As the killings proceeded, he began finding more structured and advanced methods for carrying out the executions. This consisted of using mobile gas-vans (p.3). The process in which they killed had become industrialized, like a factory. Eichmann no longer thought that any Jew should belong to the world. He no longer killed them individually, rather in groups for efficiency. In January 1942, his goal had become final. At the Wannasee Conference, Eichmann, along with 15 Nazi bureaucrats, they arranged the elimination of the 11 million Jews living in Europe and the Soviet Union3 (p.3). Following the Wannasee Conference, Eichmann became the supreme authority in managing the gathering of Jews into labor camps and newly constructed gas chambers. With great enthusiasm and fanatical efficiency, Eichmann coordinated the genocide of millions of Jews (p.2-4). Eichmann considered it a project to kill millions of Jews, and was excited about it. Eichmann killed for his own amusement, thinking about how he can do it faster, and improve his killing methods. In March, 1944, Eichmann set his eye on Hungary, which, with 725,000, contained the sole remaining big population of Jews. The deportations of Jews began from Hungary to Auschwitz, a labor camp, approximately two months later. Nearly 400,000 Hungarian Jews had been killed by the end of June. Eichmann continued to expand the areas in which he killed as he became more and more determined to exterminate the Jewish populace. Not a single trace of mind in Eichmann thought about saving the Jews in any way. However, by the end of 1944, Eichmann was ordered to terminate the deportations seeing as Germanys empire was now surrounded and almost sure to be defeated. Eichmann paid no attention to the commands as he was determined to extinguish all Jews. Instead, he ordered 50,000 Hungarian Jews to begin an eight day death march to Austria. Eichmanns personal goal in life to was kill Jews. No command or person could stop his unwavering will to kill all Jews. He could not fathom the concept of saving any Jewish lives. I will now discuss Adolf Eichmanns influence in the development of social, political, and economic history during Hitlers rule. Due to Eichmanns looks and dark complexion, his schoolmates teased him by nicknaming him ââ¬Å"the little Jew,â⬠(p.1). He was therefore associated with Jews from an early age. This may have sparked his interest in the Jewish culture and caused him to sympathize with them which is why he, at first, was uninterested in killing them. Hitler ordered the ââ¬Å"physical extermination of the Jews.â⬠Eichmann rose in the ranks to be in charge of this order because he had qualifications such as his knowledge on Jews. During his trial, he insisted he was merely ââ¬Å"following orders,â⬠saying that he was transmitting information from his superiors. He was basically obeying the law by following orders; and in case he didnt, he would be shot (p.4). When Eichmann realized the potential fortune he could extort from the Jews by giving them a safe way out of their country, he established offices of that purpose in Vienna, Prague, and Berlin. In July, 1941, Heydrich, a close partner of Eichmanns, was told to organize ââ¬Å"a general plan of the administrative and ââ¬Ëfinancial measures necessary for carrying out the desired Final Solution of the Jewish question,â⬠(p.3). Throughout their mass murdering they would have to think about ââ¬Ëfinancial measures. Therefore, at the death camps, all possessions were taken from the Jews and channeled into secret Reichsbank accounts. Eichmann had massive financial gains from his actions, and his greed may have been the cause for his determination to continue. To conclude, Eichmann essentially was ââ¬Å"the man who changed his mind in the treatment of Jews.â⬠At first, his final intentions to commit genocide on the Jews seemed impossible as he aimed to relocate the Jews. However, before long he had changed his mind and began his plans to eliminate the Jewish population. He disregarded his sense of morality more and more as he built up his power and, even when told to cease the massacre, he continued. Socially, Eichmann was teased, being nicknamed ââ¬Å"the little Jew.â⬠Politically, he followed orders and rose in the ranks of the Nazi party. Economically, a tremendous amount of money was gained. I would be lying if I said the biography didnt interest me. The paper gave a good insight into the life of Adolf Eichmann and how the Jews were treated during World War Two. Being Jewish myself, I had never realized how big an impact Eichmann had on the holocaust until I read the paper. I was horrified by the amount of control one person could have on an entire ethnic group. It can definitely be recommended as it clearly shows a persons transition from being normal to one of the person responsible for the murder of six million Jews. However, the biography contains little detail, being only three pages long; and it does not describe his psychological change sufficiently. However, it provides a good introduction to Eichmanns life. From the paper, I learned how Eichmanns mindset changed over time. He went from trying to relocate the Jews; to killing individual Jews; to trapping and killing a section of Jews; to mass-murder of the European Jewish population. In the end, he became addicted to murdering Jews, and could not be stopped. In addition, I learned how ruthlessly the Jews were treated during World War II. By Eichmann, they became viewed as insignificant ââ¬Å"toys,â⬠for his enjoyment. The methods of killing them were brutal. It was like a factory process, with gas chambers killing thousands at a time. Many Jews would die of starvation or disease in concentration camps. In Russia, all Jews from a selected village would assemble; where after they would be shot kneeling, subsequent to giving up their clothes and valuables.

medea :: essays research papers
The tragic play Medea is a struggle between reason and violence. Medea is deliberately portrayed as not a ââ¬Ënormal womanââ¬â¢, but excessive in her passions. Medea is a torment to herself and to others; that is why Euripides shows her blazing her way through life leaving wreckage behind her. Euripides has presented Medea as a figure previously thought of exclusively as a male- hero. Her balance of character is a combination of the outstanding qualities of Achilles and Odysseus. The problem set at the beginning of the play is that Jason has decided to marry another wife, Glauce. Medea is angered and will not let Jason off without punishment. The loss of Jason is not only a matter of passion; Medea has been completely humiliated by Jason's decision to take a new bride. Her pride shows again when she refuses Jason's aid. Though her situation is difficult, she would rather destroy all than accept help from one who has wronged her so horribly. Living as a barbarian among Greeks has made her more defensive, more full of hurt pride. To punish Jason, Medea had her children deliver poisoned gifts to the new bride, to kill her children, Glauce, and Creon. . Medea is not without feeling, nor is she a sociopath. She comprehends the difference between right and wrong, but chooses to follow the dictates of rage. Medeas character can be portrayed as a combination of the outstanding qualities of Achilles and Odysseus. Medea was a sorceress and held political power, Achilles was the Greek armiesââ¬â¢ best warrior and was well respected, and Odysseus was the king of Ithaca and had much respect. However each of these characters possessed weaknesses which eventually lead to their downfalls. Like Achilles and Odysseus, the gods for her betrayal punished Medea. Achilles and Medea were both tough and seemingly invulnerable characters yet both were wounded deeply by the actions of others. Achilles suffered a fatal shot to the back of his heel with an arrow that had been laced with the blood of the hydra while Medeaââ¬â¢s heart was broken when Jason left her for another woman. Like Odysseus, Medea was separated from her family and loved ones because of actions she took against both her family and gods. medea :: essays research papers The tragic play Medea is a struggle between reason and violence.

Mental Health Counseling: Integrating Consultation
Abstract With the meshing of consultation and advocacy, mental health counselors can both assist in dealing with the issues that their clients face personally, but also help to make better the world around them. In order to respond to the thesis questions presented in this paper, we must first define consultation and social justice advocacy within the counseling context. Typically, consultation means a general meeting or conference between parties.In the counseling context however, we can say that it ââ¬Å"usually involves three parties: a consultant, a consultee, and a client system. The consultant delivers direct service to the consultee, who delivers direct service to a client systemâ⬠(Doherty, 1990). Consultation for professional counselors typically involves acting on behalf of an identified client (or student) through interaction with another professional consultee or other stakeholder in the clientââ¬â¢s welfare (Brown, Pryzwansky, & Schulte, 2010; Kampwirth, 2006; K urpius & Fuqua, 1993).The consultee may also be conceptualized as a system or organization that serves an identified client or student population (Brown et al. , 2010; Moe & Perera-Diltz, 2009). With these definitions, a counseling consultant relationship could be thought of as a chain of assistance in dealing with client issues. Advocacy, typically in regards to social justice, is a way in which a change is brought into society. In a historical context, the mental health reforms that Clifford Beers brought about in the late 1800s were an impactful form of social advocacy.Beers launched one of the earliest client-advocate health reform movements in the United States. A former patient who was institutionalized for three years, Beers led national and international efforts to improve institutional care, challenge the stigma of mental illness, and promote mental health. His efforts resulted in a major shift in attitudes toward mental illness, as well as the introduction of guidance coun selors in US schools and the inclusion of evidence of a defendant's psychological state in law courts (Parry, 2010).Consultation and social justice advocacy may not be exactly similar, but they can be used as cohesive tools that counselors use in order to help their clients. Though scholars continue to identify concerns regarding how the specific nature and scope of social justice advocacy for counselors will be defined (Nelson-Jones, 2002; Roysircar, 2009; Weinrach & Thomas, 2004), in 2003 the American Counseling Association (ACA) endorsed the creation and publication of the Advocacy Competencies (Lewis et al. , 2003) for professional counselors.Along with the publication of this special issue, scholarship has focused on making the case for social justice (Prilletensky & Prilletensky, 2003; Vera & Speight, 2003), and on synthesizing the social justice counseling paradigm with other key counseling perspectives such as multicultural theory (Constantine et al. , 2007; Crethar et al. , 2008) and school counseling (Bemak & Chung, 2008; Dahir & Stone, 2009). The idea of meshing consultation with social advocacy is prudent because we as counselors should work not only to better the lives of our clients but of the world around them.There seems to be an obvious association with mental health and the groups to which social justice advocacy is most needed. Negative experiences of historically marginalized groups can lead to psychological dysfunction and an overall decline in mental health (Chang, Hays, & Milliken, 2009). The American Counseling Associationââ¬â¢s Code of Ethics states that counselors should ââ¬Å"recognize historical and social prejudices in the misdiagnosis and pathologizing of certain individuals and groups and the role of mental health professionals in perpetuating these prejudices through diagnosis and treatment. The need for counselors to integrate social justice advocacy with consultation stems from the fact that much of the clientele that is s eeking out mental health services have suffered in some form or another from social injustice(s). It is imperative in cases like this that a balance is made between providing both consultation and advocacy to our clients. In working with populations that have experienced social injustices such as poverty, racial intimidations, abuse, etc. t is the responsibility of the counselor to be the voice for those who cannot speak up for themselves. Practices such as collaborating with multiple stakeholder groups and identifying institutional polices that may promote marginalization of vulnerable community members are used by both consultants (Brown, 1993; Kampwirth, 2006) and advocates (Vera & Speight, 2003). While it is important to understand the social injustices that many clients face, it is also critical to know exactly why these injustices occur.It is also important that counselors attempt to change the structures that are responsible for the oppression of mental health clients. This s ocial justice movement is sometimes referred to as professional counselingââ¬â¢s fifth force (Ratts, Dââ¬â¢Andrea, & Arredondo, 2004)ââ¬âin other words advocacy counseling. Counseling is indeed an effective and powerful tool in helping the less fortunate with their problems. However, counseling by itself is cannot be used to advance clientsââ¬â¢ wellbeing. There must be an interlocking of counseling, consultation and social advocacy.That is, the oppressed clientele would greatly benefit from outside consultants that have the capability of promoting change within the corrosive environments in which they live. Authors Ratts and Hutchins (2009) have also highlighted how counselors-as advocates often adopt the role of consultant to promote empowerment of clients and students (Moe, Perera-Diltz, Sepulveda, 2010). Advocacy can play an important role in many aspects of alleviating the plight of the oppressed population of mental health clients.For example, advocacy can assist in supporting equitable access to needed medical services. It can also help to reduce the discrimination experienced by consumers within the health care system by facilitating communication with health care providers and by addressing any prejudicial beliefs health care providers may hold. Finally, advocates can assist consumers in addressing any discrimination that they may experience within the health care system (Stylianos & Kehyayan, 2012).If not for the advocacy of interest groups, doctors, nurses, patients, politicians, etc. the recent healthcare system changes may never have been signed into law which would have left millions still without access to affordable healthcare coverage or being denied access for discriminatory reasons. If a client does not have health insurance or the means to pay for services, a consultant could be utilized as a third party source in order to help the client have access to mental health services.Consultants in this situation could range from a soc ial worker, a career counselor or welfare office. The importance of childrenââ¬â¢s mental health in early development has long been documented, and many advocates have made impassioned pleas for additional resources for both children and their parents during the early years. A hypothetical program in which a mental health counselor could serve both as a consultant and an advocate would be to have counselors readily available to under privileged pre-school children in an outside child-care setting.The counselors could serve as a means of providing intervention of serious future problems that these children may have as they mature. These counselors can also help teachers and parents deal with issues of challenging behavior or even learning disabilities. The function of a mental health counselor that is serving as a consultant in this type of surrounding would be very different than they typical one-to-one therapy that usually occurs between counselor and client.The role of a consul tant in this sort of program would be to work as a team with a child-care center staff to recognize and deal with difficult behaviors and/or learning behaviors successfully. They would also serve as coach or mentor to families dealing with challenging issues at home and could help them access quality behavioral health services outside of the pre-school setting. In regards to social advocacy in this hypothetical program, emphasis can be made on the lack of healthcare afforded to children. According to a report from the U.S. Surgeon General, current estimates of children that are not being provided health care services are vast: ââ¬Å"one in five children is estimated to have a mental health problem that impairs functioning, while less than half of all children and one third of adults with a diagnosable mental disorder receive any kind of servicesâ⬠. Inadequate finances from families of mentally ill children can be a main reason that children go without quality mental health ser vices. Another cause can be attributed to the stigma surrounding mental illness.This can ring exceptionally true among low-income families and minorities. To erase this type of stigma, it may be helpful for a mental health consultant in this type of program to ease into the role of therapist as one-to-one counseling may be too overwhelming for those who come into the process with a set of preconceived beliefs. They could offer classes on how to deal with a childââ¬â¢s difficult behavior or problem specific support groups such as a group for single parents learning to deal with their childââ¬â¢s emotions.The job of a mental health counselor is rewarding in that it offers scores of opportunities to impact the lives of others, not just through one-to-one counseling but also through being the voice of the less fortunate through consultation and advocacy. A dedicated counselor should not only provide a sympathetic ear for a client to speak to, but should also take advantage of thei r power to promote real change for those who really need it.By incorporating both consultation and advocacy into a counselorââ¬â¢s course of action into the treatment plans of their clients, both counselor and client will build an even stronger rapport than thought possible.

My Business Management and Leadership Style Essay
Management involves getting things done through other people. Leadership, at its best, means inspiring staff to achieve demanding goals. Management style is all about investigating and satisfying your employeesââ¬â¢ motivational needs. My main management style would be democratic. This means I would listen to others opinions and take them into account, however I would still have the final decision. I am open to suggestions in the workplace and eager to change policy where necessary as a result of good suggestions. Problems and their solutions can be obtained from quality circles, which I would use in my organisation. Being mostly democratic I would use delegation. This is where my subordinates are entrusted with tasks. This is a motivator as there is a commitment to complete a task effectively. I believe it is important to also be paternalistic and autocratic. I should share an interest in the lives of my employees and what is important to them. They will feel you value them as a person and not just as a worker. I would praise individuals and give incentives, such as bonuses. This would increase motivation and job enrichment. In some areas of business being autocratic is necessary, especially for health and safety reasons and if a task needs to be undertaken over a strict time period. Some people often look for a strong leader to tell them what to do. Overall, I believe the management style is important as the employees have a significant impact of the growth of a company. Each style of management can work effectively in different situations.

Free Essays on The Butterfly
Everyone has something that they value let it be achievement, beauty, justice, or wealth. The late Manly Hall once said that "a man without ethics is a wild beast loosed upon this world" because without standing for anything or having any values a man is lost within himself, so how can he function properly in the world. In " The Butterfly" by James Hanley, value plays a key role in the backdrop of the plot. The two main characters in this short story have different values which is why a conflict arises between them. In the world today, many people have differences and society as a whole needs to start accepting the differences in people and learn from them. The main characters have no similarities in what they value while Brother Timothy values the religious faith, Cassidy values aesthetics. The way Brother Timothy puts his religious faith on such a high pedestal gives the reader the idea that he believes that "religion is the sole technique for the validating of values". Allen Tate, the author of this quotation, describes how strongly Brother Timothy feels about religion. In the very beginning of the story, the reader finds out that Brother Timothy obviously is a priest because as he " strode up and down the passage" his " cassock made a peculiar swishing noise" ( 1,1,1). Since this is so, the reader can infer that Brother Timothy dedicates his life to the Catholic church, and to do that it must be of great value to him. Beyond that, Brother Timothy also displays his value of religion when he tells Cassidy that because he misses mass that he has " no right to be happy or anything else" ( 2,13,1). The reader can infer from this quote that Brother Timothy believes so strongly about religion that he doesnââ¬â¢t even want Cassidy to be happy just because he m isses one day of mass.

Free Essays on The Butterfly Free Essays on The Butterfly Everyone has something that they value let it be achievement, beauty, justice, or wealth. The late Manly Hall once said that "a man without ethics is a wild beast loosed upon this world" because without standing for anything or having any values a man is lost within himself, so how can he function properly in the world. In " The Butterfly" by James Hanley, value plays a key role in the backdrop of the plot. The two main characters in this short story have different values which is why a conflict arises between them. In the world today, many people have differences and society as a whole needs to start accepting the differences in people and learn from them. The main characters have no similarities in what they value while Brother Timothy values the religious faith, Cassidy values aesthetics. The way Brother Timothy puts his religious faith on such a high pedestal gives the reader the idea that he believes that "religion is the sole technique for the validating of values". Allen Tate, the author of this quotation, describes how strongly Brother Timothy feels about religion. In the very beginning of the story, the reader finds out that Brother Timothy obviously is a priest because as he " strode up and down the passage" his " cassock made a peculiar swishing noise" ( 1,1,1).

A A A A A A A A A A A British Airways facilitates flight reserve and booking utilizing the on-line cyberspace services in which clients can easy entree. Trying to look competitory and keep its unity as one of the best air hoses which emphasizes quality client services, BA strives to make high-end terminus installations and other services affecting comfy of clients while onboard. BA reaches out to 570 in approximately 134 states. Such magnitude of operations offers clients with assortment of finishs with world-class services that cater clients runing from adventurers to executives. Strength aÃâ ? It is one of the best company in air hoses. aÃâ ? Ambition to be no. 1 air hose in the universe. aÃâ ? Innovated. Failing aÃâ ? Competitive capablenesss. aÃâ ? Intangible assets. aÃâ ? Controversy Opportunity aÃâ ? Economic conditions aÃâ ? Expectations of stakeholders aÃâ ? Technology Menaces aÃâ ? Clangs aÃâ ? Technical jobs aÃâ ? Changes in market Strengths The strength of the air hoses bring in the perfect services in new fleet, and the best aircraft s purchased to supply the comfy going experience of travelers. This move made to oppose the province of travel and complains which they receive by the old fleet used by British air passage. The degree of British Airways operation is astonishing and, British Airways get an advantage on his rivals by to supplying the wider assortment of services to clients in comparing to the other rival air hoses such as virgin Atlanta air passages have a effect of operations15 times lesser than the British Airways is a great assortment of paths flatters this great magnitude of operations these factors makes the services of BA more easy to nearing client in UK and around the universe. The basic strength of the British Airways ( BA ) that served the full organisation for old ages is to present an equal solution for travelers in a most safety and hearty manner ( Chan, 2000 ) . Aside from the usage of assorted marketing schemes on the global web, the air hose selling and service are performed by most of the females. Prior to the equal labour for both genders, it is considered as the strength of the organisation for most of the females are trained to talk in assorted idioms.

Failings The global selling reply of the British Airways is wholly prioritising most of the demands of the clients. But in their scheme in a low cost-ticket can be hazardous in a long tally of the concern. Offering the low monetary values for tickets may non look harmful in the concern but decidedly, if the concern has greater outgo over the grosss, there will see drastic losingss ( Binggeli and Pompeo, 2002 ) . The creative activity of the low-priced bearers can weaken the services of some countries because the allotted budget will non fulfill the proposed usage of service ( Berry, Carnall, and Spiller, 2006 ) . It was exposed that company has a regulation of non let grownup male riders to siting following to the alone kids, even if the parents of that kid are someplace else on the plane. It led to the allegation of sex favoritism. British Airways come across contention.

The norm of lost luggage s is 46 % for 1000 riders carried, they lost 23 bags. Opportunity The organisation s thought about pull offing the people first is a enormous chance for their employees. The leaders can make a section wherein most of the people can concentrate on the assorted selling schemes such as publicities to heighten the fight of the organisation in the industry ( Gowler, Ledge, and Clegg, 1993 ) . Another chance that the organisation may happen is their advantage in the usage of the quality engineerings.

British air passages have the concern category merchandise named Club Europe, and they offered on all short flights. At most of airdromes riders can utilize the concern sofas and are acquire served a breakfast in the forenoons flights or complete breakfast on ulterior flights ( jambon, salami etc. ) and if the flight subsequently in the twenty-four hours clip they served afternoon tea. Club Europe has form of 2+3 on 5 instead than 6 seats, but in first category and 2nd category they have a mini place in center. The aircraft can be adjust in 3+3pattern in order to do the aircraft to the full economic system. Menaces The chief menace for any air hose is clangs, climatic conditions, terrorist act and diminution in ticket gross revenues due to recession and proficient job in the aircrafts. Menace from the terrorists attacks many air hoses stop their flights to some states, such as British Airways halt flight to specific states such as Middle East and the chief states occupied with terrorist activities and have fright of their planes can be attack by them. Other major part of the British Airways menace is the increased competition among the air hose industry. Through the different competitions, there is a huge option for the clients and most of them choose the best monetary value and service that is fit on their budgets. Through the development of the different geographic expeditions, there is a position for the amalgamation and acquisitions ( Culpan, 2002 ) . The confederation in the air hoses is popular in which the schemes are bind together and the exclusive action of the organisation is limited. STRATEGIC OPTIONS In order to remain with the competition and to maintain the clients interested, they undertake batch of publicity activities. BA jointly organizes big figure of publicities with the other companies functioning the similar mark customers.BA gets in touch with riders, mark trueness nine members.

An debut to the program and to the company.This would include the A?overview of the company, its background, company type, size, turnover, construction and mark markets.A? Porter s Five Force of the British Air passages Competitive competition As the survey of the industry competition originating from the competitions among bing houses in the first force. In the planetary confederation industry British air passages provide Boeing and lading services and they have rivals like Lufthansa air hoses, Swiss airways, Virgin Atlanta, Delta, FedEx, and DHL. At same cost BA is supplying the more quality services than the other air hoses. New entrants Merchandises within the industry were greatly differentiated, with changing grades of quality, convenience, client service, and differences in the ambiance. New entryway will be low in the international confederation sector. The strongest presence of Lufthansa and American air hoses will be the chief rivals for the BA. British air passages are besides a celebrated air hose like others but for new entrants it will take old ages to be popular in confederation sector. A amalgamation program opens by British Airways and Iberia Airlines. In their amalgamation understanding the air hoses and their trade names names are similar to KLM and Air France. Substitute Open Skies, is the new air hose started and flies from Paris and Amsterdam to New York is the subordinate of British air passages British Airways World Cargo, is besides subordinate of the BA emmet it is the universe s twelfth-largest lading air hose based on entire freight ton-kilometers flown. BA City Flyer is a subordinate with Avro RJ aircraft in Edinburgh, but they runing chiefly from London City Airport. Buyers British Airways offers perfect services for riders going in the premium cabins and riders with position. Alliance industry has a batch of competition in the air hose sector, so the monetary value of the tickets alterations twenty-four hours by twenty-four hours to pull the more clients. The clients of the air hoses are largely concern or tourers. BA purpose is countered by foreign bearers such as Emirates, who fly direct from UK provincial airdromes to Dubai, Abu Dhabi etc and it has being successful. Suppliers Before the Heathrow airdrome British Airways purchase accoutrements and equipment slots from other air hoses companies including United Airlines, body mass index, Brussels Airlines, GB Airways and Swiss International Air Lines, and now they have their owns about 40 % of slots at Heathrow. The chief PEST factors that have influenced confederations are: Political. Politically, air hoses have to work within some are runing limitations. The benefits of the join confederation industry that will be near an unapproachable path. This has a monopoly that each national bearer ties in with slots, in their place metropoliss. The air hose industry acquire two sided understandings this is another political benefit for industry, which all member can use. Political environment concern about the function of authorities and its effects on the company. Economic. Europe capacity in exceeds demand, which leads to rate wars, bing lower give manner for companies increase the addition. Economically, they can cut down the competition and increase the manner to derive by lead industry to command on capacity. Airline menus are non split when the industry cut down the airdrome enlargement by codification sharing air hoses, but they offer services and enter in markets, they might afford to make on their ain. The less aircraft at airdromes, hence less infinite being required for aircrafts on airdrome, and this is the other technique to derive right to utilize premier airdromes, which can non increase further. Simmons, K Lewis, J Barrett 2000. Social. Cost can be reduced by using merely air hose s staff, air hose in confederations or codifications portion from employer staffing point of position these are strong. The demand and gustatory sensation which summarized by the societal environment and fluctuate market tendency and non refundable income, and alterations happens in market, both chances and menaces for peculiar confederation company can be provided once more. Technological. In this fast traveling industry engineering is of import and really expensive. The engineering which is usage in aircrafts is made by really few companies for illustration ( Rolls Royce ) makes the engines and other accoutrements for aircrafts. For purchase new engineerings it will necessitate support and perchance employees has to be trained before the equipments used by them. Recommendation British Airways is one of the best air hose in confederation industry with its new engineerings and good services. The company is able to pull more clients by supplying them some more services. They should hold more of the client service and trueness plans. The company should supply price reductions for their corporate clients. The company should acquire in touch with their clients when they have some promotional offers. Decision British Airways remains carefully optimistic about its hereafter chances. However, it is certain that well more work lies in front if the air hose is to win. The FSAS program incorporated by BA resulted in considerable cost nest eggs, and divestments besides raised financess to pay off debt. The end of the FSAS program was to accomplish a 10 % runing border and therefore more recent cost cuts and occupation loses have been made by Willie Walsh order to carry through this. In air travel, a great trade of success or failure depends on external factors, with BA enduring severely in the wake of the 2001 and 2005 terrorist onslaughts, , the war in Iraq and the planetary economic lag. However, the individual most of import external factor is the monetary value of fuel. Fuel monetary values are go oning to turn and this is likely to both erode net incomes and raise monetary values for BA. Rising monetary values could put BA in a disadvantageous place, peculiarly given the continued populari ty of budget air hoses. This is an of import factor for Willie Walsh to see. Walsh must understand that the cardinal growing country for BA is likely to be in value-added travel. In some countries, BA found that it could better clients experience while cut downing costs, such as in its edifice up of on-line gross revenues. Other value-added services are likely to see mid-priced flights being upgraded, as air travel continues to go more competitory. Overall, BA, through Walsh, must go on to endeavor to cut down costs and better client and employee satisfaction.

Characteristics of a Good Editor
Characteristics of a Good Editor You dont have to work for a magazine or newspaper to benefit from the help of a good editor. Even if she seems nit-picky with her line edits, remember that the editor is on your side. A good editor addresses your writing style and creative content, among many other details. Editing styles will vary, so find an editor that gives you the safe space to be creative and make mistakes simultaneously.à The Editor and the Writer Carl Sessions Stepp, the author of Editing for Todays Newsroom, believes editors should practice restraint and refrain from immediately reshaping the content in their own images. He has advised editors to read an article all the way through, open your mind to the logic of the [writers] approach, and offer at least minimal courtesy to the professional who has dripped blood for it.à Jill Geisler of The Poynter Institute says a writer must be able to trust that an editor respects the writers ownership of a story and can resist the temptation to completely write a new and improved version. Says Geisler, Thats fixing, not coaching. ... When you fix stories by doing instant rewrites, there may be a thrill in showing off your skill. By coaching writers, you discover better ways to craft copy. Gardner Botsford of The New Yorker magazine says that a good editor is a mechanic, or craftsman, while a good writer is an artist, adding that that the less competent the writer, the louder the protests over editing. Editor As Critical Thinker Editor-in-chief Mariette DiChristina says editors must be organized, able to see the structure where it does not exist and able to identify the missing pieces or gaps in logic that bring the writing together. [M]ore than being good writers, editors must be good critical thinkers who can recognize and evaluate good writing [or who] can figure out how to make the most of the not-so-good writing. ... [A] good editor needs a sharp eye for detail, writes DiChristina.à A Quiet Conscience The legendary, shy, strong-willed editor of The New Yorker, William Shawn, wrote that it is one of the comic burdens of [an] editor not to be able to explain to anyone else exactly what he does. An editor, writes Shawn, must only counsel when the writer requests it, acting on occasion as a conscience and helping the writer in any way possible to say what he wants to say. Shawn writes that the work of a good editor, like the work of a good teacher, does not reveal itself directly; it is reflected in the accomplishments of others. A Goal-Setter Writer and editor Evelynne Kramer say the best editor is patient and always keeps in mind the long-term goals with the writer and not just what they see on the screen. Says Kramer, We can all get better at what we do, but improvement sometimes takes a lot of time and, more often than not, in fits and starts. A Partner Editor-in-chief Sally Lee says the ideal editor brings out the best in a writer and allows a writersà voiceà to shine through. A good editor makes a writer feel challenged, enthusiastic and valuable. An editor is only as good as her writers, says Lee. An Enemy of Cliches Media columnist and reporter David Carr said the best editorsà are the enemiesà of clichà ©s and tropes, but not the overburdened writer who occasionally resorts to them. Carr stated that the perfect traits of a good editor are good judgment, an appropriate bedside manner and an ability to conjure occasional magic in the space between writer and editor.

Hitler table talk, 1941-1944 Essay Example | Topics and Well Written Essays - 1250 words
Hitler table talk, 1941-1944 - Essay Example In this book, Hitler freely talks about his friends, failures, enemies, ambition and secrete dreams. During the midday and evening hours, Hitler turned down his guard to have a conversation with his most trusted men. Martin Bormann, Hitlerââ¬â¢s acting private secretary, persuaded Hitler to allow him compiles the various conversations that were recorded by different people into a book. Hitler after his renowned tyranny had the plans to use this book as a reference material to write on the Thousand-Year Reich. In Hitlerââ¬â¢s table talk book, there are 328 entries that were made with specified dates and time. Hitlerââ¬â¢s close allies such as Todt, Himmler and other military leaders with exception of Goering were described to be present during these conversations as they could even pose questions to Hitler to which he responded. Hitler was such a person who contributed to any topic of discussion you could imagine of and he is the person that guided the directions of most talk s. During that period there was a war that was going on, but something interesting is that no talks were based on the war issue. Apparently these talks were mostly meant to divert peopleââ¬â¢s attentions from the war that was going on. Hitler was the German leader who was well educated and he specialized in the European history. He was a great racist and hated the Jewish people very much which worsened day after day. Some of the recorded statements involve Hitler narrating his strategic plans during the late 1932 power struggle and the resistance the Nazi party was subjected to. During that time, it is fascinating to see Hitler describing himself as the ââ¬Å"builderâ⬠of capital cities, autobahns, and museums something that is ironical. Contrasts between Hitlerââ¬â¢s support for Christianity and His hatred for the same In most of the recorded conversation, Hitlerââ¬â¢s hatred for Christianity is more common than those of the Jews. Some of his negative talks about Chr istianity that supports Hitlerââ¬â¢s hatred for Christianity includes; ââ¬Å"what is this God who takes pleasure only in seeing men grovel before himâ⬠(Adolf & Gerhard, p143). ââ¬Å"A negro baby, who has the misfortune to die before a missionary gets his clutches on him, goes to Hellâ⬠(Adolf & Gerhard, p69). ââ¬Å"The catastrophe, for us, is that of being tied to a religion that rebels against all the joys of the nonsenseâ⬠(Adolf & Gerhardp142). ââ¬Å"Christianity is the worst of the regressions that mankind can every have undergoneâ⬠(Adolf & Gerhard, p322). ââ¬Å"While we are on this subject, letââ¬â¢s add that, even amongst those who claim to be good Catholics, every few really believe in this humbug. Only old women, who have given up everything because life has already withdrawn from them, go regularly to the churchâ⬠(Adolf & Gerhard, p342). ââ¬Å"Our apoch will certainly see the end of the disease of Christianityâ⬠(Adolf & Gerhard, p 343). Hitler contradicts himself when he pretends to supports Christianity by saying ââ¬Å"Christianity sets the example. What could be more fanatical, more elusive and more intolerant than this religion which bases everything on the love of the one and only God whom it revealsâ⬠(Adolf & Gerhard, p397). Other than Christianity, Hitler resisted the renewal of Wotan worship. From the book it is not difficult to realize that Hitler was a consummate rationalist. This is revealed when he said ââ¬Å"but there will never be any possibility of National Socialismââ¬â¢

Shuttle Wagons Project Plan Essay Example | Topics and Well Written Essays - 1250 words
Shuttle Wagons Project Plan - Essay Example After completion, the tunnel is meant to join the United Kingdom and France. It will be the longest underwater tunnel in the whole world with a total length of 50 kilometers. The tunnel is inherently a rail transport system, which will enable Eurotunnel, to avail a dive-on shuttle service for the normal road vehicles between the two terminals. Project background Eurotunnel contracted TransManche Link (TML) for the building of the channel tunnel. TML then subcontracted different roll shock manufactures for the buildings of the Shuttle Wagons. The project had a tight timescale and had heavy liquidated damages that were associated with the delays. This paper looks at the design and the manufacture of the transport vehicles called the Shuttle Wagons. The first half of the passenger shuttles comprises a locomotive, twelve single deck wagons for the coaches, the off-loaded wagon, and a loader wagon. The other half is comprised of a similar design but has a two-tier system of wagons for car s. Each single deck is designed to carry a coach while the double deck wagons are designed to carry a maximum of five cars in every deck, which adds up to ten in a single wagon (Harris, 2006 p32). The wagons were designed to enclose the passengers in the vehicles providing a fire resistance for thirty minutes. The reason for this design was that the journey from one terminal to another takes about five minutes. If, by chance, a fire started at the time the shuttle enters the tunnel, the fire would be contained up to the time the shuttle will reach the other end of the tunnel. The policy of keeping the passengers in the shuttle until the wagon reached its destination enables any residual incident to be dealt with in the specially designed emergency siding (Harris, 2006 p67). There was the need to have a drive on and off system that required the unrestricted access to the entire length of the twelve wagon units during the loading and the unloading process. The design concept also requ ired each wagon to be self-contained with a fire resisting enclosure for the whole journey; it was essential to have fire shutters at the end of each wagon. Identification of project management related issues The design parameters became a challenge and had to ensure that there is minimum protrusion into the wagon in practice. The design also had to incorporate pass doors through which passengers were expected to evacuate in case of emergencies like a fire outbreak, it has a minimum of 30 minutes of fire resistance and could withstand the pressure regime of the shuttle passing along the tunnel. The shutters also had to have a minimum leakage rate to maintain the least fire extinguishing concentration of Halon within the Wagon (Harris, 2006 p67). The major aspects of the design operation and construction of the channel tunnel required the approval of the intergovernmental commission. The major focus, at the beginning of the project, was on the safety, security, defense, and the envir onmental issues. This shows that at first the design parameters were not certain during the designing phase (Harris, 2006 p45). Partly in the middle of the project, it became emerged that the design changes
Professional identity Term Paper Example | Topics and Well Written Essays - 1500 words
Professional identity - Term Paper Example Nonetheless, the theory requires the nurse to employ both professional and generic knowledge and means to fit such varied thoughts into nursing care actions and objectives. In this scenario, care skill and knowledge are frequently redesigned for the best interest of the patients (Shaw & Timmons, 2010). Therefore, all care modalities in Hennepin County Medical Center will need the participation of both the nurse and patients working together to recognize, plan, execute, and assess every care mode for culturally fitting nursing care. These modes will stimulate the nurse to develop nursing decisions and actions using cultural based ways and new ways to offer satisfying and meaningful inclusive care to the large diverse population in downtown Minneapolis. If this nurse values and understands the practice of culturally proficient care, she will have the ability to encourage positive changes in health care activities for patients of diverse population at Hennepin County Medical Center in d owntown Minneapolis. In addition, for the nurse to share a cultural identity with the large population of diverse individuals, she will need knowledge of transcultural nursing principles and ideas together with an understanding of existing research findings. It is significant for the nurse to note that culturally proficient nursing care can only take place when the values and beliefs of patients are skillfully and thoughtfully included into the nursing care plans of Hennepin County Medical Center. Caring is the central focus of nursing. Therefore, culturally proficient nursing will guide the nurse to offer optimal inclusive, culturally centered care. Part B Out of the three primary roles for the baccalaureate-prepared registered nurse identified by the American Association of Colleges of Nursing, the role the writer is most interested in exploring is that of a case manager. A case manager is a health care expert, particularly a registered nurse, who dedicates himself or herself in a ssisting patients with their health care needs and services. This is from the period the patients are admitted to the medical institution to the period they are discharged (Lai & Lim, 2012). Also, case managers are referred to by more general terms, as medical case managers or nurse case managers. In addition, nurse case managers work hand in hand with patients and their relatives or loved ones to examine the needs of the patient and come up with an ample health care plan that highlights their preferences and objectives (Baldwin, 2012). There are also certain education requirements that need to be met for a person to become a nurse case manager. Nurse case managers characteristically possess an associateââ¬â¢s degree in nursing as the lowest educational requirement. However, some have a masterââ¬â¢s or bachelorââ¬â¢s degree to signify an advanced level of training and knowledge. In addition to certification and educational achievement, registered nurses can augment their ch ances of becoming nurse case managers if they have shown immense attention to detail, have significant connection with patients and their loved ones, and are terrific supervisors of their nursing staff. It also helps to have a specified amount of years of experience in the field of nursing. The writer has had a concentration, a segment of the patient population on which she has focused her greatest interest.
How successful was industrialization in Australia over the period 1950 Essay
How successful was industrialization in Australia over the period 1950 to 1973 - Essay Example (R8:3). The development of manufacturing is complicated. It involves a great variety of products, fragmentation of the industry, different markets between six states as well as a wide range of operations (R8:3). Industrialization of Australia first began with its heavy, complex and diversified manufacturing during the First World War. Since the Second World War it has become one of the most highly industrialized economies in the world (R6:182). Australia played a major role in promoting post-war industrialization; however, its welfare state interventions created a great barrier in its later manufacture development. The major growth phase of post war manufacturing development was between mid 1940s and late 1960s. In 1944, it announced that it ââ¬Å"is ready for an adventurous expansion of secondary industries in the post-war periodâ⬠(R5:15). This essay will examine Australian manufacturing development over the period 1950 to 1973 and the impact of industrialization during this period. Section one will examine the importance of industrialization to the Australian economy. Then, we examine success and impact of industrialization to the economy. This included the impact on employment, capital investment, public infrastructure, country import and export as well as the protection policies implemented by the state during this period. After examining the advantages brought by industrialization, the essay criticizes on the effectiveness of welfare state interventions to the Australian economy. During World War Two, Australian foreign debt was due to the sales of goods and services to the United States. This can be accounted for the high demand in food stuffs by other industrialized countries. A high price was paid for Australian primary products (R4). Its dependence on foreign capital rose. At that time, foreign investment, foreign technologies, foreign management, foreign

Corporate finace - Essay Example Online Travel Portal Limited used to be the former name of Opodo Limited prior to July 2001. It is a subsidiary of Amadeus IT Holding, South Africa. However, it is based in London, UK and was incorporated in the year 2000. The Financial Times reported that Permira Advisers Ltd. and AXA Private Equity seem to join hands together for the purpose of buying Opodo Limited from Amadeus IT Holding SA at the cost of â⠬500 million that is equal to USD 682.5 million. The prime objective of the planned buyout is to develop the best online booking services provider through merging the Opodo Limited with the eFreame and Go Voyages SA. Also, the American Carlyle Group has shown some intend to buy Opodo limited due to which the bids for Opodo exceeded â⠬400 million since any bid would probably be challenged by Carlyle Group. Some sources reported that the Permira would bid through Vacaciones eDreams, S.L. where as the Axa would be bidding through Go Voyages SA. The process of this sale wi ll be handled by the JPMorgan Chase. Permira and Axa have been bidding against each other for the acquisition of medium sized European web based travel agencies prior to joining together so as to acquire Opodo Limited. In the last year, Permira defeated Axa so as to acquire eDreams-Spanish online agency where as the Axa won against Permira for the acquisition of Go Voyages. After which they together planned to develop a giant European agency through merging the Opodo Limited, after its acquisition if their bid for it is successful, with the previously acquired eDreams and Go Voyages. At present, the Amadeus IT Holding owns the Opodo Limited and this business venture involves only 4 % of their entire business turnover. Financial Performance Indicators Financial performance indicators for the three companies are provided below. Chart 1: Annual Sales Permira Advisers Ltd for the Last 5 Years in Million USD. The chart 1 given above provides interesting information about the annual sales of the Permira Advisers Ltd that enables us to apprehend the performance of the company before the acquisition of OPODO Limited. Chart 2: Annual Sales AXA Private Equity for the Last 5 Years in Million USD.

The Work of Representation Essay Example for Free
The Work of Representation Essay 1 Representation, meaning and language At first we have to know thatï ¼Å¡ Representation is an essential part of the process by which meaning is produced and exchanged between members of a culture. It does involve the use of language, of signs and images which stand for or represent things. And surly it is not a simple or straightforward process. How this article exploring the concept of representation connect meaning and language to cultureï ¼Å¸ We will be drawing a distinction between three different account or theoriesï ¼Å¡the reflective, the intentional and the constructionist approaches to representation. Most of this text will be exploring the constructionist approach with two major variants or models of the constructionist approach, the semiotic approach- Ferdinand de Saussure and the discursive approach- Michel Foucault. But we have to answer the question firstï ¼Å¡what does the word representation really meanï ¼Å¸ 1.1 Making meaning, Representing things Representation is the production of the meaning of the concepts in our minds through language. There are two processes, two systems of representation. First, there is the system by which all sort of objects, people and events are correlated with a set of concepts or mental representations which we carry around in our heads.ï ¼Ëlike chair, tableï ¼â° Second, Language is therefore the second system of representation. (When we say we belong to the same culture, it is because we interpret the world in similar ways. Thatââ¬â¢s why culture is sometimes defined in terms of shared meaning or shared conceptual maps. However we must also able to represent or exchange meanings and concepts.) The relation between things, concepts and signs lies at the heart of the production of meaning in language. The process which links these three elements together is what we call Representation. 1.2 Language and Representation As people who belong to same culture must share a broadly similar conceptual map, so they must also share the same way of interpreting the signs of a language. In the SHEEP example: In order to interpret them, we must have access to the two systems of representation: to a conceptual map which correlates the sheep in the field with the concept of a sheep: and a language system which is visual language, bear some resemblance to the real thing of looks like it in some way. The relationship in the system of representation between sign, the concept and the object to which they might be used to refer is entirely arbitrary.(Tree will not mind if we used the word Seert to represent the concept of them) 1.3 Sharing the codes The meaning is constructed by the system of representation. It is constructed and fixed by the code, which sets up the correlation between our conceptual system and our language system in such a way that, every time we think of a tree the code tells us to use the English word TREE, or Chinese word æ ¨ ¹. The code tells us that in our culture! One way of thinking about culture is in terms of these shared conceptual maps, shared language systems and the codes which govern the relationships of translation between them. Not because such knowledge is imprinted in their genes, but because they learn its conventions and so gradually become culture persons. They unconsciously internalize the codes which allow them to express certain concepts and ideas through their systems of representation. But of our social, cultural and linguistic conventions, then meaning can never be finally fixed, we can all agree to allow words to carry somewhat different meanings. Social and linguistic conventions do change over time. 1.4 Theories of representation In the reflective approach, meaning is thought to lie in the object, person, idea or event in the real world, and language functions like a mirror, to reflect the true meaning as it already exists in the world. We can also call it as mimetic approach. The second approach to meaning in representation argues the opposite case. It holds that it is the speaker the author, who imposes his or her unique meaning on the world through language. Words mean what the author intends they should mean. This is the intentional approach. The third approach recognizes this public, social character of language. Things donââ¬â¢t mean: we construct meaning, using representational systems. Hence it is called the constructionist approach. 1.5 The language of traffic lights The simplest example of this point, which is critical for an understanding of how languages function as representational systems, is the famous traffic lights example. According to the constructionist approach, colors and the language of traffic lightsââ¬â¢ work as a signifying or representational system. In the language of traffic lights, it is the sequence and position of the colors, as well as the colors themselves, which enable them to carry meaning and thus function as signs. It is the code that fixes the meaning, not color itself. This also has wider implications for the theory of representation and meaning in language. It means that signs themselves cannot fix meaning. Instead, meaning depends on the relation between a sign and a concept which is fixed by a code. Meaning the constructionist would say, is relational. 2. Saussureââ¬â¢s legacy In the important move, Saussure analysed the sign into two further elements. There was, he argued, the form, and there was the idea or concept in your head with which the form was associated. Saussure called the first element, the signifier, and the second element the signified. Signifierï ¼Å¡ The word or image of a Walkman, for example Signifiedï ¼Å¡ The concept of a portable cassette-player in your head Saussure also insisted on what we called the arbitrary nature of the sign: There is no natural or inevitable link between the signifier and the signified. Signs do not possess a fixed or essential meaning. What signifies, according to Saussure, is not RED or the essence of red-ness, but the difference between RED and GREEN. Signs are members of a system and are defined in relation it the other members of that system. Furthermore, the relation between the signifier and the signified, which is fixed by our cultural codes, is not permanently fixed. BLACK is dark, evil etc. BLACK is beauty. However, if meaning changes, historically, and is never finally fixed, then it follows that taking the meaning must involve an active process of interpretation. There is a necessary and inevitable imprecision about language. 2.1 The social part of language Saussure divided language into two parts. 1.The first consisted of the general rules and codes of the linguistic system, which all its users must share, if it is to be of use as a mean of communication. Saussure called the structure of language, the langue. 2.the second part consisted of the particular acts of apeaking or writing or drawing, which are produced by an actual speaker or writer. He called this, the parole. For Saussure, the underlying structure of rules and codes was the social part of language, the part which could be studied with the law-like precision of a science because of its closed, limited nature. The second part of language, the individual speech-act or utterance, he regarded as the surface of language. In separating the social part of language from the individual act of communication, Saussure broke with our common-sense notion of how language worksâ⬠¦Ã¢â¬ ¦ The author decides what she wants to say, but she cannot decide whether or not to use the rules of language. Critique of Saussureââ¬â¢s model In his own work, he tended to focus almost exclusively on the two aspects of the sign-signifier and signified. He gave little or no attention to how this relation between signifier/signified could serve the purpose of what we called reference. Another problem is that Saussure tended to focus on the formal aspects of language-how language actually works. However, Saussureââ¬â¢s focus on language may have been too exclusive. The attention to its formal aspects did divert attention away from the more interactive and dialogic features of language. Later cultural theorist learned from Saussureââ¬â¢s structuralism but abandoned its scientific premise. Language remains rule-governed. But it is not a closed system which can be reduced to its formal elements. 3.From language to culture: linguistics to semiotics The general approach to the study of signs in culture, and of culture as a sort of language, which Saussure foreshadowed, is now generally known by the term semiotics. The French critic, Roland Barthes, he brought a semiotic approach to bear on reading popular culture, treating these activities and objects as signs, as a language through which meaning is communicated. In much the same way, the French anthropologist Claude Levi-Strauss, not by analyzing how these Amazonian peoples, but in terms of what they were trying to say, what messages about the culture they communicated. In the semiotic approach, not only words and images but objects themselves can function as signifiers in the production of meaning. Clothes, for example. In this example, we have moved from the very narrow linguistic level from which we drew examples to a wider, cultural levelâ⬠¦Ã¢â¬ ¦Barthes called the first, descriptive level, the level of denotation: the second level, that of connotation. 3.1 Myth today In his essay Myth today, in Mythologies, Barthes gives another example which helps us to see exactly how representation is working at this second, broader cultural level. a.A black soldier is giving the French flag a salute. b.The Panzani ad for spaghetti and vegetables in a string bag as a myth about Italian national culture. Think of ads, which work in the same way. 4. Discourse, power and subject Already, in Roland Barthesââ¬â¢s work in the 1960s, as we have seen, Saussureââ¬â¢s linguistic model is developed through its application to a much wider field of signs and representations. Semiotics seemed to confine the process of representation to language, and to treat it as a closed, rather static, systemâ⬠¦some people had more power to speak about some subject than others. Models of representation, these critics agued, ought to focus on these broader issues of knowledge and power. Foucault used the word representation in a narrower sense than we are using it here, but he is considered to have contributed to a novel and significant general approach to the problem of representation. What concerned him was the production of knowledge through what he called discourse. His work was much more historically grounded, more attentive to historical specificities, than the semiotic approach. As he said ââ¬Ërelation of power, not relation of meaningââ¬â¢ were his main concern. 4.1 From language to discourse Foucault studied not language, but discourse as a system of representation. By ââ¬Ëdiscourseââ¬â¢, Foucault meant ââ¬Ëa group of statements which provide a language for talking bout a particular topic at a particular historical momentâ⬠¦.Discourse is a bout the production of knowledge through language. Discourse, Foucault argued, never consist of one statement, one text, one action or one source. The same discourse, characteristic of the way of thinking or the state of knowledge at one time, will appear across a range of texts, and as forms of conduct, at a number of different institutional sites within society. However, whenever these discursive event refer to the same object,â⬠¦Ã¢â¬ ¦, then they are said by Foucault to belong to the same discursive formation. Nothing has any meaning outside of discourse. 4.2 Historicizing discourse: discursive practices Things meant something and were true, he argued, only within a specific historical context. He thought that, in each period, discourse produced forms of knowledge, objects, subjects and practices of knowledge, which differed radically from period to period, with no necessary continuity between them. The mental illness example The homosexual example The hysterical woman example Knowledge about and practices around all these subjects, Foucault argued, were historically and culturally specific. They did not and could not meaningfully exist outside specific discourse. 4.3 From discourse to power/knowledge In his later work Foucault became even more concerned with how knowledge was put to work through discursive practice in specific institutional settings to regulate the conduct of others. This foregrounding of the relation between discourse, knowledge and power marked a significant development in the constructionist approach to representation which we have been outlineing. Foucaultââ¬â¢s main argument against the classical Marxist theory of ideology was that it tended to reduce all the relation between knowledge and power to a question of class power and class interests. Secondly, he argued that Marxism tended to truth. But Foucault did not believe that any form of thought could claim an absolute truth of this kind, outside the play of discourse. The Gramsciââ¬â¢s theory has some similarities to Foucaultââ¬â¢s position. Knowledge linked to power, not only assumes the authority of the truth but has the power to make itself true. The Regime of truth! Secondly, Foucault advanced an altogether novel conception of power. We tend to think of power as always radiating in a single direction and come from a specific source. It is deployed and exercised through a net-like organization. This suggests that we are all, to some degree, caught up in its circulation- oppressors and oppressed. 4.5 Charcot and the performance of hysteria The activity 7, look the figure 1.8 and answer the follow questions. (page 54.) 5. Where is the subject The conventional notion thinks of the subject as an individual who is fully endowed with consciousnessâ⬠¦Ã¢â¬ ¦it suggests that, although other people may misunderstand us, we always understand ourselves. Indeed, this is one of Foucaultââ¬â¢s most radical propositions: subject is produced with discourse. Foucaultââ¬â¢s subject seems to be produced through discourse in two fidderent senses or places. First, the discourse itself produces subject. But the discourse also produces a place for the subject. Subject-positions 5.1 How to make sense of Velasquezââ¬â¢ Las Meninas 5.2 The subject of/in representation Look the Diego Velasquezââ¬â¢ Las Meninas, and follow the question in activity 9. 6. Conclusion: representation, meaning and language reconsidered Representation is the process by which members of a culture use language to produce meaning. Meaning, consequently, will always change, from on culture or period to another. Because meanings are always changing and slipping, codes operate more like social conventions than like fixed laws or unbreakable rules. In semiotic, we will recall the importance of signifier/signified, langue/parole and myth, and how the marking of difference and binary oppositions are crucial for meaning. In the discursive approach, we will recall discursive formation, power/knowledge, the idea of a regime of truth, the way discourse also produces the subject and defines the subject-positions from which knowledge proceeds and indeed, the return of questions about the subject to the field of representation.

Analysis of Optical Imaging Technologies
Analysis of Optical Imaging Technologies PAI is a relatively new imaging modality which displays optical absorption contrast with a high resolution at depths of up to a few centimetres. Tissue is illuminated using short laser pulses and ultrasound waves are generated within the tissue upon optical absorption. An image is formed of the optical absorption contrast based on the arrival times and amplitudes of the acoustic waves (Wang 2009, Lai and Young 1982, Sigrist and Kneubuhl 1978, Jaeger 2007). It began in the late 19th century, when Alexander Graham Bell discovered the extraordinary effect of sound being generated because of absorption of intermittent sunlight (Bell 1880, 1880a). It was not until the 1970s and 1980s that research in this field took off, with the advent of modern pulsed lasers and materials and electronics for acoustic detection and recording. Pulsed laser light, indeed, is used in the majority of PAl techniques in order to illuminate the sample of interest. The succession of phenomena that occur after light exposure is shown in the following list (Wang 2009, Xu and Wang 2006): Light absorption: the molecules that absorb light, start vibrating and this continues until the illumination ceases. Temperature rise: the vibration locally increases the temperature for the period of illumination, after which the temperature decays. Thermoelastic expansion: because of the thermoelastic effect, the heated area tends to expand, with a local increase in pressure for the period of illumination if this happens to quickly for expansion to occur. Acoustic emission: the transient pressure variation propagates away from the transiently heated region. The initial studies were based upon gas-phase analysis, in which gases, depending upon their physical properties would absorb specific wavelengths of pulsed laser radiation, generating acoustic signals recorded by a microphone (Tam 1986, Meyer and Sigrist 1990). It wasnââ¬â¢t until the mid-1990s that biomedical applications of photoacoustics were reported (Kruger 1995, Esenaliev 1997, Hoelen 1998) and from that point, until now, the field has witnessed unprecedented growth to a stage where imaging systems are commercially available. The generation of PA signal can be understood by dividing the phenomenon into two domains: ââ¬ËOpticalââ¬â¢ and ââ¬Ëacousticsââ¬â¢ (Kruizinga 2010). In the optical domain, the pulse of light incident on the body surface above the site of interest, penetrates and travels diffusely through the different layers and encounters regions where it is absorbed, causing the generation of heat, which results in volumetric expansion. If this heat is deposited in a short enough time using a nano- or femtosecond laser pulse, then there is no time for dissipation of heat into the surrounding medium nor dissipation of the stress due to the heat-induced increase in pressure, and a transient disequilibrium arises, because of the difference in pressure inside and outside the region of heat deposition. This results in the generation of acoustic emissions, which propagate to be detected at the body surface via the acoustic domain. In the next few sections, these two sub-domains (optical and a coustic) will be explained, followed by a brief outline of the possible imaging applications of PAI. 2.1.1à Optical domain In medical imaging, the wavelength range of 650 nm to 1300 nm is often referred to as the `tissue optical window, wherein the tissue components, primarily haemoglobin, water and melanin absorb minimal light, allowing greater penetration of the photons than at other wavelengths. The two processes that dominate in light interacting with tissue are `scattering and `absorption. The strength of these interactions heavily depend on the wavelength of the light used and the components of the interacting tissue. Before looking into the optical domain, it is necessary to define some common optical parameters and quantities, as listed in Table 2.1. Table 2.1. Definitions of some common optical parameters and quantities With these parameters, it is possible to define the extinction coefficient , as in Equation 1.1[JCB1]. Its reciprocal would be the mean free path between any absorption or scattering events. . (1.1)[JCB2] In order to take into account the anisotropy of light scattering, while evaluating the scattering property of a tissue (as it contains a combination of organelles and cells, ranging in size from nm to à ¼m), another scattering coefficient is defined (Cheong et al. 1990). It is called the reduced (or transport) scattering coefficient and it is equal to: , (1.2) where g is the anisotropy factor, which is around 0.9 for tissue in the Vis-to-NIR [JCB3]wavelength range. The approximation of light transport through tissue is given by the diffusion theory. Here the attenuation (a) of light is approximated per unit length d with the use of Beers law , and the effective attenuation coefficient à µeff [JCB4]is given by (Cheong et al. 1990, Oraevsky et al. 1997): , (1.3) Unlike the all-optical imaging modalities, the resolution of PAI does not suffer heavily from the scattering of photons. In fact, scattering within the tissue lead to a more homogenous distribution of photons, which can be useful for effective PA wave generation. The limiting factor that PAI shares with other optical techniques is the low penetration depth of light in tissue. Nevertheless PAI only requires the delivery of light in one direction, and ultrasonic scattering is two to three orders of magnitude weaker than optical scattering in tissue. Therefore PAI allows for high spatial resolution much deeper within tissue than all-optical imaging, and can image to much greater depths than most of the other optical imaging techniques. 2.1.2à Acoustic domain The imaging principle of PAI does not rely on the reflection of an acoustic wave, as in ultrasound imaging, but rather on the detection of an acoustic wave generated from absorption of light. The generation of PA [JCB5]waves occurs only when the incident laser pulse [JCB6]length satisfies the stress confinement condition (Xu and Wang 2006, Jacques 1993). The stress confinement criterion is satisfied when the laser pulse length is shorter than the time ( ) for the stress waves to dissipate from the region of optical absorption: ,(1.4) where, is a representative linear dimension, such as the diameter of the absorbing region or the depth of penetration of the laser beam into the absorbing region, and is the speed of sound in tissue. In general, a pulse width of 3-10 ns is used in PAI. Pulse lengths greater than tens of nanoseconds do not produce a situation that satisfies the stress confinement criterion and generates either a very week or no PA signal. Pulses much shorter than a few nanoseconds lead to the generation of weaker PA signals from tissue. The generated acoustic signals propagate radially from the source, and the amplitude of the PA wave indicates the extent of local optical absorption, while the spatial origin of the acoustic waves, which indicates the location of the absorber, can be determined by the wave shape at the body surface, as given by the time taken for each part of the wave to reach the transducer surface, after laser irradiation. The initial PA pressure generation caused due to thermoelastic expansion can be rewritten as (Oraevsky and Karabutov 2003, Gusev and Karabutov 1993) ,(1.5) where à ² is the thermal expansion coefficient, Cp is the specific heat at constant pressure, c is the speed of sound in the absorbing object, F is the light fluence and is the optical absorption coefficient. is referred to as the Grà ¼neisen coefficient ( and H (= is the local energy deposition density. With this equation, it is possible to estimate the intrinsic sensitivity of PAl techniques, which expresses how much the pressure signal amplitude would increase, if the fluence of the laser radiation is increased by a given amount. The acoustic wave that is generated upon light absorption obeys the following wave equation (ignoring thermal diffusion and kinematic viscosity) (Tam 1986, Sigrist 1986, Diebold et al. 1991, Gusev and Karabutov 1993). (1.6) The left side of equation represents the normal wave equation where v[JCB7] is the speed of sound in the medium of propagation, P pressure and t time. The right side describes the PA source, where à ² is the thermal expansion coefficient, Cp is the specific heat at constant pressure and H is the amount of heat generated following light absorption. H can be represented as the product of optical absorption coefficient à ¼a and the light fluence F (. The PA wave equation (1.6) formalized above can be considered as the key formula used for the construction of PA images, whereby, a linear relation between optical absorption and the measured acoustic amplitude is assumed. [JCB1] Just like figures and talbes, all equations should be referred to in the text. Otherwise, why is the equation there? [JCB2] This is how to centre an equation. Dont use any tabs. Right justify the line, and put spaces between the equation and the equation number until the equation is centred by eye. Why have you used a really tiny font for the equation number? I recommend that you dont do this. Also, even the equations themselves in this thesis are very small. It is boarderline acceptable. Slightly larger would be better. Of course do not make the in-line equations bigger. Finally, rules of grammar also apply to equations. If the finish a sentence or represent a sentence on their own, they should be followed by a full stop. If the are followed by the continuation of a sentence then appropriate punctuation should be used. For example, when they are followed by where variable is given by symbol, then the equation should end in a comma and the word where should begin with a small w. You will find this to be copied from all the good journals and books. [JCB3] Do not use abbreviations that you have not defined. [JCB4] Be careful to make sure that all symbols are correctly italicised and subscripted as appropriate. I wont be able to correct many of these if there are more of these problems. [JCB5] Needs defining. First use is at the beginning of section 1.2.1. [JCB6] Time does not have a width. [JCB7] Do not mix symbols. You said above that c is the speed of sound.
