Free Trade War Free Essay Example, 1500 words

Free trade is based upon the philosophy of liberalism which believes in freedom at all levels. Liberalism not only advocates the freedom at the individual level but at the society and economy level also wherein it suggests that the economy should be free from any interference of the government. Free trade, however, creates economic interdependence between the countries thus making war an unlikely option for the participants. This view is often based upon the overall philosophy underlined in the liberalism and international relations theory which governs the overall relationships of the States with each other. (Steger, 2002) Considering the perspective of international relations, liberalism suggests that those states which have mutually beneficial economic relations with each other are less likely to engage in war with each other. This view, however, is based upon the assumption that States are not technically unitary actors but rather they are dependent upon each other as long as t hey depend upon each other economically. States, therefore, do not operate as single humans but rather as mutually dependent actors whose survival actually depends upon the survival of each other.

States, therefore, do not operate as single humans but rather as mutually dependent actors whose survival actually depends upon the survival of each other. If the States actually engage in war with each other, their mutual economic dependence may not last for longer. In a globalized world where countries are connected with each other through sophisticated telecommunication networks, this dependence has greatly increased the odds of survival if countries actually cooperate with each other rather than engaging into war with each other. (Chandra Chari. , 2010) In an increasingly mutually beneficial world, there are many competing actors within and at the international level. Further, the presence of institutions such a s WTO also creates external actors who are competing and independent of the State. The competing nature of actors within the States actually continues force States to abandon any plans which can instigate war with the countries which are of mutual benefit to the country.

Task Free Essays

There are efferent acts for different types of discriminations that must be followed by professional workers in any types Of settings. Sometimes promoting Anti- Discriminatory Practices may be threatening to workers as there are great changes in legislation time to time. The legislations are there to prevent Care Workers from discriminating towards Client Service users. We will write a custom essay sample on Task or any similar topic only for you Order Now Disability is a state or function that can be judged severally as damage taken place. It causes consequences such as physical, sensory, cognitive and intellectual impairments due to mental illnesses and different types of diseases and situations. It effects individual’s organ or body part and may also effect individual’s participation in life. This is why there is an Anti- Discriminatory practice that promotes disabled individuals in participating in life and protects individuals from getting discriminated. The act that am going to talk about is the Disability Discrimination Act 2005 (DAD) that relates to Disability. The main purpose of the Disability Discrimination Act 2005 is to improve the lives of Disabled people by allowing them to carry out day to day activities. However, it does not mean the legislation creates new individual sights for the Disabled people. The act is there to prevent individuals from getting discriminated due to the disabilities. The act ensures that all individuals are entitled to civilian rights in the way that they are entitled to goods, services and facilities that are needed for their needs. The DAD is also there to encourage other communities to help provide regulations which would break the barrier that has been causing discrimination; this is done providing reasonable adjustments like: Providing Transport but also booking premises check if wheelchairs etc are accessible. Share personal details if needed. Improve access route within the location. -: Communicate with disabled person about services that are provided and explain how to improve accessibility. Updated Technology for example: Telephone with text displayed for a Deaf person. -: Treat disabled person like any other customer (Respect and Value them) Provide readers and interpreter for meetings, interviews or consultation. -: Employers or individuals should remember that not all disabilities can be seen, some can be hidden. Encourage the community to support and encourage disabled people. Anti- Discriminatory Practices being promoted in a Health and Social Care setting In order to promote Anti- Discriminatory Practices in the Health and Social Care Settings, Care Workers must train, keep up to date with changes within the legislations, policies and technology as procedure may change over the years, as procedures may change, Care Workers must learn the new procedures to continue on their professionalism in the Career. Care Workers must be informed about the changes in Equality, Diversity and Rights and also any other aspects of Health and Social Care such as the four ethical Principles, Hess are sectors that must be taken into account to protect the Client Service Users, the sectors are: Justice- this is where people must be treated fairly with respect no matter the differences. An example of this would be, even though a man may be Dyslexic, he should be treated with respect rather than treating him stupidly. Anatomy- this is where a person’s choice must be valued. : Beneficence- this is where Care Workers take respond and take action in way that benefits their Client Service Users. They take on risks and costs. An example of this may be, cost of Electronic Wheelchair for a person ho cannot walk. -: Non- Maleficent- this is where Care Workers shouldn’t let harm caused by treatments and inventions affect the benefits of their treatment with the Client Service Users. An example of this may be, even if a disabled person has been treated in a Hospital and feels a lot better, A Care Worker cannot say: ‘Your feeling better, you don’t need me, another Client needs my help more than you. This sort of behavior is not acceptable and professional as Care Workers main purpose is too help anyone who is in need of help. These four principles are there to help guide Care Workers On how to protect Client Service users. Other than the Four Ethical Principles, there are also other procedures that will help Care Workers to keep professionalism and to also help Client Service User by following the Care Value Base, Charter of Rights and the Code of Practice; The Care Value Base is Principles that would help keep Care Workers and Client Service Users relationship professional. These Principles are: The promotion of Anti- Discriminatory Practice. An example for this would be promoting the Disability Discrimination Act 2005 for Disabled People. The promotion and support of dignity, independence and safety. Care Workers should look after the well-being of a Disabled individual. -: Respect for and Acknowledge of personal beliefs and an individual’s identity. Care Workers should show the Disabled person that although they have their difference, they are valued in the same way as any other individual. They won’t be treated unequal. : The maintenance of Confidentiality. Care Workers should prove to the Disabled person that Care Worker can be trusted unless there are risks; Confidentiality may be broken in order to prevent any trouble of harm. -: Protection from abuse and Harm. Care Workers should ensure Disabled people that their Health and Safety is very important The promotion of effective communication and relationship. An example for this would be a Deaf person, as they cannot hear; Care Workers may bring in for them a worker who may be able to communicate with them through Signs. The promotion of personalized (individual) care. An example of this would be that the disabled individual would be entitled to care that fits their needs. In Health and Social Care, Charter of Rights is standards that are expected from the Service. Client Service Users are entitled of these rights. For instance, as for a Disabled person they are entitled to: Right to be respected. Disabled person should feel that they are valued although they may not be the same as others. Rights to Safety from Harm. Disabled people should feel as if they are protected. Right to be allowed Privacy. Disabled people should feel as if they have some space no matter what their situation may be. Right to Confidentiality. Disabled people should feel as if they can trust the Health and Social Care Settings. Right to have access on you. Disabled people should feel as if they are entitled to looking at their own deiced health status. -: Right to independence and Choice. Disabled people are entitled to being dependent on them and should always be entitled to choices. Right to Freedom of Speech. Disabled People should feel as if they can have a say in anything. They should feel as if they are allowed to express their feelings or opinions etc. Right to be seen within a reasonable time scale. Right to celebrate your own Culture and Beliefs. Disabled people should feel as if their Cultures and Beliefs are respected and valued. Right to be able to communicate in your own language. Disabled people should be allowed to speak in their own language; therefore, Care Workers should bring in translators or interpreters etc. Right to be supportive. Disabled people should feel as if Care Workers are by their side. They shouldn’t feel alone and lonely. Right to make their own decisions. Disabled people should be allowed to decide on choices that relates to them and decisions shouldn’t always be made for them. Code of Practice is another way of promoting Anti- Discriminatory practice. It is there to guide Care Workers on their roles, responsibilities and rights. It is there to remind Care Workers of what their job is about. The practices for this act are: To respect Diversity of Clients, to be Non- Discriminatory. To treat with Equality and Equity. To respect their Rights, Cultures and Beliefs of Client Service User. : To empower Client Service Users. To promote independence and choice of Client Seen,’ice Users. Not to Marginal’s or Disemboweled Client Service users. These principles and the DAD are there to guide Care Worker. Care Workers in the right direction but to also allow them to feel as if they are committed to the Principle and Legislations. Furthermore, Care Workers can also rumoring individual rights ; these can be shown in waiting rooms, receptions, canteens etc, for Client Service Users to see, but to also show Client Service Users that Care Workers are taking their job seriously. Furthermore, promoting individual rights can be read out to Client Service user, not only that, if Care Worker is unsure, they are also provided a handbook, which shows Equality, Diversity and Rights, so that their job can still stay professional. Care Workers can also empower individuals, so that individuals feel as if they are able to make choices and decisions on their own behalf. Care Workers do his to show Client Service Users, that the Health and Social Care settings are there to support them but to also show them that, the service only care about their best interests. The Principles and the DAD is there to also inform Client Service Lesser that they are equal and same as any other individual. The Principle and the DAD are there to promote to Anti- Discriminatory Practice. To prove to Disabled people that they do not tolerate any sort of discrimination but to also show that the Health and Social Care Settings are by their sides. Asses the influence of a recent National Policy promoting Anti – Discriminatory Practice The DAD 2005 is the amended version of the Disability Discrimination Act 1995. The Disability Discrimination Act 1 995 main purpose was to promote rights and encourage organizations. However the DAD 2005 promotes towards the public, the main purpose of the law is to promote the Disability equality and produce action plans for the public. This Legislation also goes toward people with HIVE and Students with Disabilities. The Anti- Discriminatory Practice is there so that the public can also follow Laws and Regulations that would prevent discrimination towards people who may have capabilities, this is done by ensuring that all services are planned and covered. If any one does not follow these regulations, scones ounce will come across. Difficulties that may arise when implementing Anti – Discriminatory Practice in a Health Social care Settings The Difficulties that may arise when implementing Anti-Discriminatory Practices in Health and Social Care settings are that if Care Workers are not prepared or motivated in their jobs they may discriminate as they will not realize. Furthermore, not following Code of Practices, Charter of Rights and Care Value Base, this would lead to discrimination as Care Workers and Client Service would not have any Rules and Regulations to follow. Not only that, if Care Workers are not trained properly, Client Service User may not attend sessions which could cause future problems in the society as Client Service Users may not understand the Rules and Regulations that are set up for them. Not following professional standards can also lead to Diplomacy Actions and dismissal. Successes of Recent Initiative in Promoting Anti- Discriminating Practice The Disability Discrimination Act 2005 is a law, which means that if anyone goes against this law, serious acts would take into consideration. The main repose of the law is eliminating discrimination toward people who have disabilities. The act ensures that every individual is treated with Equality, Diversity and Rights. This is why promoting Anti- Discriminatory Practice is successful, as it is a method of preventing discriminations. Successful as the Disability Discrimination Act 2005 and other Anti- Discriminatory Practices are there to promote all individuals to follow Procedures and Policies. For instance, in the Health and Social Care Settings, there is applying the Care Value Base, which is there for both Care Workers and Client Service users in alluding up relationships, so that no discrimination is caused between them, or the Charter of Rights which is there for Client Service Users, to inform them on what they expect from organizations or the Code of Practice which is there to remind Care Workers to treat Disabled people or other people fairly, equally and respectfully etc. Furthermore, the Legislations is also successful as there is contain uses training provides for Care Workers and also Technology, Procedures are always updated, which means Procedures would work along side with the coming years. The Legislations also helps as it helps Care Workers to empower individuals and help care workers on how to deal with any sort of discrimination or conflicts which may occur or vice versa, if individuals are discriminated, they would know what help to get. Ways of Overcoming Difficulties which may arise when implementing Anti- Discriminatory Practices. There are ways of overcoming difficulties when implementing Anti- Discriminatory Practices. For instance, in the Health and Social Care Setting, Care Workers are trained with skills: seeing both sides of the arguments. Being willing to listen. : not taking sides. Not sulking and letting things fester. Ewing good at quick thinking. -: Looking for solutions and not getting bogged down in personal issues. These are skills that sort Conflict. Care Workers must be â€Å"Professional and Positive† as negativity can cause more problems. Furthermore, other ways of overcoming difficulties is by giving advice and guidance (rights) by implementing from the government of policies and guidelines by manager. Furthermore, explaining to worker and individuals of the consequence when breaking the rules Of the Anti- Discriminatory practices. Care Workers can use the Complaints Procedure. These are procedures that al organizations and smaller work places have to follow as the law has made this one of the way of sorting out any conflicts. The Compliant Procedure is there to show Client Service User that any Complaints they have would be dealt effectively and efficiently as Complaints are not acceptable. The Health and Social Care Setting would investigate Complaints properly, even after dealing with Compliant, if Client Service Users are not satisfied with the procedures; they may complain further or even be entitled to receive compensation if they are harmed. The Anti- Harassment is another policy where all organization must follow a logic of law which deals with any sort of harassment. Harassment on the basis of Sexuality, gender, disability, belief etc Advocacy is another way of overcoming any difficulties as a Care Worker is there to represent their Client Service User as they may be young, vulnerable or even elderly. They support their Client so that they don’t get discriminated or neither feels as if they are alone. Conclusion In conclusion, a National Initiative is a policy that is implemented by the government. This is why Anti- Discriminatory Practices are put into organizations so that individuals are not discriminated. How to cite Task, Papers

Mitosis Meiosis free essay sample

In science class this week, weve been learning about cell reproduction. What is Cell division? What is Mitosis? What is Meiosis? How are they alike? How do they differ? All of these amazing questions will be answered, if you decide to read on. The Cell Cycle A life cycle begins with an organism’s formation, followed by its growth and development, and the production of offspring that will repeat the cycle, before ending in death. Right now, I am in a stage in the life cycle called adolescence, which is a period of active growth and development. Similar to the life cycle, cells undergo a cycle too. It’s called the cell cycle. The cell cycle is a series of events that take place from one cell division to another. A human life cycle and a cell cycle have many things in common. The main thing they have in common is that they’re both cycles. We will write a custom essay sample on Mitosis Meiosis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page They both help in the areas of reproduction and growth. Although they have things in common, they also differ. One thing they have different is that at the end of a life cycle, the organism dies however; the cell cycle continues to reproduce. In the cell cycle, cells can reproduce asexually and sexually, but in the human cycle, humans reproduce sexually. This is how the cell cycle and the human cycle compare and contrast. Cell Division What is cell division? Well, cell division is the term that describes cell reproduction. Cell division is also the process in which cells reproduce. In cell division, there are two ways cells divide: mitosis with body cells and meiosis with sex cells. Mitosis is the process in which the nucleus divides to form 2 identical nuclei. Each new nucleus is also identical to the original nucleus. Mitosis is asexual reproduction. Asexual reproduction is the process in which one parent cell produces two daughter cells that are genetically identical to each other and the parent. How do body cells divide? Well, body cells divide to multiply in the cell cycle. There are three steps to the cell cycle. The first step is interphase. Most of the cell cycle is spent in the period of growth and development called interphase. During Interphase, there are three (3) phases: G1 phase, S phase, and G2 phase. During G1, the cell grows bigger and the organelles duplicate. In the S phase, the chromosomes duplicate. In the G2 phase, the cell continues to grow and prepares for mitosis. During Interphase, the nucleolus is clearly visible in the nucleus. The next step in the cell cycle is Mitosis. Mitosis involves four (4) phases: Prophase, Metaphase, Anaphase, and Telophase. During Prophase, the chromosomes or chromatid pairs are now visible and spindle fibers are beginning to form. The next phase in Mitosis is Metaphase. In Metaphase, the chromatid pairs are lined up in the center of the cell. After this Metaphase is Anaphase. In Anaphase, the chromosomes are separated. Finally in Mitosis, Telophase begins. In Telophase, two (2) new nuclei are formed. This is the end of Mitosis. Some important things about Mitosis is that in involves one division of the nucleus and it’s the production of two (2) new nuclei that are genetically identical to each other and the original nucleus. Each new nucleus has the same number and type of chromosomes. In simpler terms, the parent cell becomes two (2) identical daughter cells. The next step after Mitosis is Cytokinesis. During cytokinesis, the cytoplasm is beginning to separate as the cell divides into two (2) new genetically identical daughter cells. Then, the cells enter interphase and cell division begins again. After you read this section, you probably wondered, â€Å"Why is Mitosis important? † Well, Mitosis is important because it preserves genetic characteristics from generation to generation. What Is Meiosis? Meiosis is the process in which one parent cell produces four (4) genetically different daughter cells. Meiosis is sexual reproduction. There are two major steps in Meiosis. These steps are Meiosis I and Meiosis II. In Meiosis I, there are four (4) phases: Prophase I, Metaphase I, Anaphase I and Telophase I. In Meiosis II, there are also four (4) phases: Prophase II, Metaphase II, Anaphase II, and Telophase II. Now, you might ask, â€Å"Why is Meiosis important? † Well, the main purpose of Meiosis is that it allows diversity. This is Meiosis. Mitosis vs. Meiosis There are many differences between Mitosis and Meiosis. The main difference in Mitosis and Meiosis is that Mitosis is asexual reproduction, but Meiosis is sexual reproduction. Another primary difference between the two is that Mitosis creates body cells from existing body cells; however, Meiosis creates sex cells from body cells. Meiosis involves two (2) divisions of the nucleus, but Mitosis involves one (1) division of the nucleus. Mitosis creates two (2) daughter cells that are genetically identical, but Meiosis creates four (4) daughter cells that are genetically different. One thing similar is that they each have 4 phases which are Prophase, Metaphase, Anaphase, and Telophase. All in all, Mitosis and Meiosis are very complicated processes in which your germ cells and other cells undergo, but it’s good that you know how you reproduce.

Young and Barbara Jordan were the first two blacks from the south, since Reconstruction to be in congress.

Young improved public education and the social infrastructure in his district when he served in the committee on banking and currency and its sub-committee in housing, transportation and finance. One of his early initiatives was the urban mass transit systems such as MARTA in Atlanta. In July 1973, Young and some southern republicans successfully lobbied for a foreign bill provision that authorized the president to cancel aid that Portugal would use for military action in its African colonies. Young rejected cuts in domestic spending for the poor while supporting an increase in wages for workers in the public sector. He was reelected again for two more terms as a result of his fight for the rights of Black Americans and other minorities during his first term. In the 94th congress (1975-1977) he became the first black representative appointed to the House Committee on Rules. Young sought ways of improving the lives of his constituents by sponsoring bills that outlined comprehensive health care plans and testified on behalf of the bills that preserved food stamp programs and economic development in his districts. Ambassador To The United Nations During his third term in office, the president of the United states, Jimmy Carter asked Young to be America? s ambassador to the United Nations, a post which he accepted becoming the first African American to serve in that capacity. Whilst in office, Young helped transform America ? s foreign policy, making human rights a central focus and pushing for economic development in the third world, especially Africa. He called for sanctions against the apartheid regime in South Africa, fought for U. S. Recognition of communist Vietnam. Young was also involved in several debates regarding foreign relations, including the decision to stop supporting the attempts made by the Portuguese to hold on to colonies in Southern Africa. This was a clear demonstration of young? s role as Carter? s point-man in foreign policy in Asia and Africa. He actively played the role of articulating Carter? s position on human rights and liberal capitalism in Rhodesia, South Africa and Angola. Andrew Young resigned from his ambassadorship post due to mounting criticism of his meeting with an observer of for the Palestine Liberation Organization. Young As Mayor Of Atlanta In 1981 Young ran for Mayor of Atlanta. He was elected later that year with 55% of the vote. He succeeded Maynard Jackson. As Mayor of Atlanta, he brought billions of dollars worth of new private investment. The mayor? s Task Force on Education established Dream Jamboree College Fair that tripled college scholarships given to Atlanta public school graduates. Young was reelected mayor in 1985 with more than 80% of the vote. He expanded programs for including minority owned businesses in city contracts. It? during his tenure, that Atlanta hosted the 1988 democratic National Convention. As the co-chair of the Atlanta Committee for 1969 Olympic Games, he led the efforts of Atlanta bidding to host that summers’ Olympic Games which it won. Works In 1996 he wrote A Way Out Of No Way: The Spiritual Memoirs of Andrew Young, Published by Thomas Nelson. During the same year, Young and Carlton Masters co-founded Goodworks International, a consulting firm that offers international market access and political risk analysis in key emerging markets within Africa and the Caribbean. Awards Andrew Young has received numerous awards and honors including the presidential Medal Of Freedom, the NAACP Spingarn medal in 1978 and more than 45 honorary degrees from Dartmouth, Yale, Notre Dame, Clark Atlanta, Emory and The University of Georgia in 1993. Morehouse College, Atlanta, established the center for international studies which was later named Young center for international studies. Andrew Young is currently a professor at Georgia state University? s Andrew Young school of Policy Studies. His importance cannot be understated as he, evidently, was one of America? great leaders of the Civil Rights Movement. He strongly felt the need to address the plight of Black Americans and Championed for rights among all Americans, irrespective of race or color. His preferred addressing problems peacefully love and not hate or violence. The economic contribution he made was immense, Georgia but also outside the United States.

SHORT LISTENING ASSIGNMENT FORMAT Essay Example | Topics and Well Written Essays - 250 words - 4

SHORT LISTENING ASSIGNMENT FORMAT - Essay Example The saxophone and the trumpet both provided smooth and consistent ride patterns for most parts in the song (www.youtube.com/watch). Cool jazz is evident because this song smoothed out a combination of swing and bop tones. Furthermore, dynamics and harmonic elements were softened in this song. The classic jazz style is also evident because the musical instruments that have been used e.g. the saxophone, drums and double bass, show the classical style of jazz music. The musical arrangement incorporates many solos, which substantially embellished the rhythm and melody with ornaments that improvise jazz music. Both the saxophone and the trumpet provided smooth swings at some points within the song. The jazz group technique that I can hear in this song is the riffs, and trading in some parts within the song. The drum in the song was significantly effectively because beat can not be filled without the rhythm of the drum. In some parts of the song where there was some silence, the drum added beats which kept the band with a better feeling. The stylish integration of the double bass and the drums also provide a consistent ride pattern all through the song (ccnmtl.columbia.edu). The song was introduced by the trumpet and saxophone which brought a pleasant feeling to the whole song. Syncopation was provided by both the piano and the drum at some points within the song. I choose to the drum because its effects were the most noticeable throughout the song. Its effects were highly noticeable all through the song, and towards the end of the song, the drum brought a conclusive touch and feel into the song. It was remarkably successful because it served all its purposes in the song effectively. I loved how the drum effects were integrated in the song.  The song is pleasing to me. I appreciate the manner in which it was delivered. The thing that I liked was the way in which the instrumentalists played their roles. One

A computed tomography

A computed tomography 1. Introduction One of the most used techniques in the imagiology field is called Computed Tomography (CT), a method to acquire slices of the body based on the attenuation of X-rays. This monograph will try to compile the most important information about CT, namely its history, physical principles, fundamental instrumentation, data acquisition and processing techniques, as well as its applications. Firstly, a brief tour through the history of the technique will be taken, while some of the most important achievements will be referred. The starting point will be the discovery of the X-rays, then passing through the creation of the first CT scanner and the development of data analysis and processing algorithms. Then, a concise revision of the evolution of the scanners will be done, delineating the different generations of scanners and the key features of each one. In order to understand how an object can be scanned by this technique, a review of the physical concepts that constitute the basis of CT will be done. More precisely, we will discuss the attenuation of radiation while passing through objects. A short description of how X-rays interact with matter and the concept of linear attenuation coefficient will be discussed. The instrumentation needed for CT will shortly be referred, in particular the most important components of a CT scanner will be briefly explained. As data acquired by the scanners are not displayed in the way they are obtained, we will afterward explain the most used methods to process and analyze the great amount of information acquired by the CT detectors. The process of creating a scale to represent data the CT numbers will subsequently be overviewed, in order to understand how images are created and shown to the doctors. A description of how CT allows to distinguish different anatomical structures and how it permits to see just the structures we want will also be done. After that, an enumeration of some of the many clinical applications of CT will be done, knowing at the start that it will be impossible to list all the applications, reason why just a few will be referred. Besides, it is not the main goal of this monograph, although it is essential to understand the crucial importance of CT in the medicine field. Finally, we will try to conjecture about the future of CT, specifically what it can be improved and what are the actual challenges for this technique and how it can be overcame. This monograph is part of the Hospital and Medical Instrumentation course and pretends to be an overall view of CT, reason why there is not exhaustive detail in each section (for more detail in the approached topics, please read the references). 3-Dimensional reconstruction techniques will not be discussed because it is the topic of another group. Incisive instrumentation will not be exploited because it not exploited in the course as well. 2. Historical Background The history of CT started with the discovery of X-rays in 1895 by Wilhelm Conrad Roentgen, which gave him the Physics Nobel Prize in 1901. During 1917, the Austrian mathematician Johann Radon developed a study in which he demonstrated that making several projections in different directions of a material and recreating its associated pattern, it was possible to obtain a slice where one could characterize different densities of the material. The idea of using these mathematical methods to create images of slices of the human body in radiographic films was proposed by the Italian radiologist Alessandro Vallebona in 1930. Between 1956 and 1963, the physicist Allan Cormack developed a method to calculate the distribution of absorbed radiation in the human body based on transmission measurements, which allowed to detect smaller variations in absorption. [2], [3], [4] In the year of 1972, Sir Godfrey Hounsfield (who won the Nobel Prize in Medicine or Physiology in 1979, shared with Cormack) invented the first CT scanner in United Kingdom when he was working at EMI Company, which, at the time, was actually best known for its connection to the music world. The original prototype, called EMI Scanner, recorded 160 points for each projection in 180 different angles (with steps of 1 °) and each slice took 5 minutes to be acquired. A 180160 matrix was then constructed with these data, which took 2 and half hours to be analyzed until the final 2D-images could be visualized. The first types of scanners required the patients head to be immerged in a water-filled container in order to reduce the difference of X-rays attenuation between the rays that crossed the skull and the ones that only crossed the environment, because the detector had a small range of intensities that it could measure. [5], [6] During the subsequent years, CT scanners increased its complexity, and based on that evolution, we can distinguish five generations of machines that will be discussed in the next section (Section 3). Later, in 1989, it was developed a new technique in which data acquisition was done continuously the spiral CT scanning using the movement of the platform where the patient was lying. [4] Nowadays, CT machines have obviously superior performances than the prototypes of the 70s. In fact, several rows of detectors have been added which now allows registration of multiple slices at the same time the multislices scanners. These improvements allowed to represent data in 10241024 matrixes, which have a 1 megapixel pixel resolution. [7], [8] 3. Evolution of CT Scanners Over the time, the fundamentals of data acquisition and the key characteristics of the machines changed in many ways. This fact, allow us to split the evolution of the CT scanners in five generations. 3.1 First Generation Parallel Beam The first technique implemented in CT commercial machines consisted of the emission of a parallel X-ray beam that passed through the patient until it reached a detector located on the opposite side. Both X-ray and detector were place in the edge of a ring with the patient as the center. The X-ray source, as well as the detector, suffered a linear translation motion to acquire data from all maters directions. Then, the X-ray tube and the detector, was rotated about 1 °, having the patient as isocenter, and a new beam was emitted and the movement of translation restarted. This process was repeated until it reached 180 ° and, for each cycle of emitted beams, 160 projections of the material on analysis were recorded. The highly collimated beam provided excellent rejection of scattered radiation in the patient. At this point, the most used image reconstruction technique was the backprojection. Later in this work (Section 6) we will explain the techniques used in reconstruction. The ti me needed for data acquisition was extremely long (5 minutes per slice), due to technological limitations. [8] 3.2 Second Generation Fan beam In the second generation, the collimated beam was replaced by a fan X-ray beam and the simple detector was replaced by a linear array of detectors. This advance resulted in a shorter scan time, although this technique still continued to use a coupled source-detector translation motion. At the same time, the algorithms used to reconstruct the slice images became more complicated. Because of the vast amount of time needed to acquire data, both the first and second generations of scanners were limited to head and extremities scans, because those were the regions of the body that could remain immobilized during the long scan time. [9], [2], [8] 3.3 Third generation Rotating detectors The third generation of scanners emerged in 1976. In this generation, the fan beam was large enough to completely contain the patient, which made the translation movement redundant and the scanner commenced to execute only the rotational movement. Such as the fan beam, also the detectors became big enough to record all data of each slice at a time. The detector consisted of a line with hundreds of independent detectors that, like as in the second generation, rotated attached to the X-ray source, which required up to 5 seconds to acquire each slice. The power supply was now made by a slip ring system placed on the gantry, which allowed to continually rotate it without the need to reverse the rotating motion to untwist the power cables used before, as it was needed after each rotation in first and second generations. [2], [8] 3.4 Fourth generation Fixed detectors This generation was implemented in the late 70s and its innovation was a stationary ring of detectors that surrounded the patient. In this case, only the X-ray beam had movement. The ring consisted of a 600 to 4800 independent detectors that sequentially recorded the projections, so detector and source were no longer associated. However, detectors were calibrated twice during each rotation of the X-ray source, providing a self-calibrating system. Third generation systems were calibrated only once every few hours. In the fourth generation systems, two detectors geometries were used. The first one consists of a rotating fan beam inside the fixed ring of detectors and the second one has the fan beam outside the ring. These technological advances provided a reduction of the scan times to 5s per image and slice spacing below 1 mm. Both third and fourth generations are available in market and both have success in medical activities. [8], [2] 3.5 Fifth Generation Scanning electron beam The innovation of the fifth generation of CT scanners (early 80s) was a new system of X-ray source. While the ring of detectors remains stationary, it was added a new semicircular strip of tungsten and one electron gun which is placed in the patient alignment. By directing this electron beam to the anode of the tungsten strip, the release of X-ray radiation is induced. This method results in a no moving parts system, i.e. no mechanical motion is needed to record data because the detectors completely surround the patients and the electronic beam is directed electronically. The four target rings and the two detector banks allow eight slices to be acquired at the same time, which reduce the scan time and, consequently, the motion artifacts. This fact led to the reduction of scan time to between 33 and 100 ms, which is sufficient to capture images of the heart during its cardiac cycle, reason why it is the most used in diagnostic of cardiac disease. For that reason, this is also called U ltrafast CT (UFCT) or Cardiovascular CT (CVCT) Because of the continuous scan, special adjustments in the algorithm are needed to reduce image artifacts. [2], [8], [9] 3.6 Spiral Scanners The idea of creating a spiral CT came with the need for scans of 3-Dimensional images. This system to acquire 3-Dimensional CT images was born in the early 90s and consists of a continue translation movement of the table which supports the patient. This technique is based on the third generation of machines and allows scan times of the abdomen to be reduced from 10 minutes to 1 minute, which reduces the motion artifacts. Besides, a 3-Dimensional model of the organ under study can be reconstructed. The most complex innovation of this technique consists of the data processing algorithms, because they must consider the spiral path of X-ray beam around the patient. Technically, this was possible only due to the slip ring system implemented on the third generation of scanner. [9], [8], [10] 3.7 Cone beam After the development of new techniques, detectors, methods and algorithms, nowadays the question is: How many slices can we acquire at same time?. The answer to this question lies in the placement of several rows of detectors and the transformation of a fan beam X-ray to a 3-Dimensional cone beam. Nowadays, manufacturers have already placed 64 rows of detectors (multislice systems) and the image quality reached high levels. Moreover, the completely scan of a structure takes now about 15 seconds or even less. [2] 4. Physical Principles The basic principle of CT is measuring the spatial density distribution of a human organ or a part of the body. It is similar to conventional X-ray, in which an X-ray source of uniform intensity is directed to the patient and the image is generated by the projection of the X-rays against a film. The X-rays are emitted with a certain intensity I0 and they emerge on the other side of the patient with a lower intensity I. The intensity decreases while crossing the patient, because radiation interacts with matter. More precisely, X-rays used in CT are of the order of 120kV and, with that energy (120 keV), they interact with tissues mainly by photoelectric (mostly at lower energies) and Compton effects (at higher energies), although they can also interact by coherent scatter, also called Rayleigh scatter (5% to 10% of the total interactions). Photoelectric effect consists of the emission of an electron (photoelectron) from the irradiated matter caused by the absorption of the X-rays energy by an inner electron of the medium. In Compton effect, a X-ray photon interacts with an outer electron of matter and deviates its trajectory, transferring part of its energy to the electron, which is then ejected. In coherent scatter, the energy of the X-ray is absorbed by the tissue causing the electrons to gain harmonic motion and is then reradiated in a random direction as a secondary X-ray. [10], [11], [12], [13], [14] CT X-rays are not monoenergetic, but for now, to simplify the understanding of this concept, we will consider them monoenergetic. When an X-ray (as well as other radiation) passes through a material, part of its intensity is absorbed in the medium and, as a consequence, the final intensity is lower than the initial one. More precisely, the Beers Law states that intensity transmitted through the medium depends on the linear attenuation coefficient of the material  µ if we consider that we are in presence of a homogeneous medium and the thickness of the material x according to the following expression: The problem with conventional radiographs is that it only provides an integrated value for  µ along the path of the X-ray, which means that we have a 2-Dimensional projection of a 3-Dimensional anatomy. As it can be easily understood, all the structures and organs at the same level will appear overlapped in the image. As a consequence, some details cannot be perceived and some organs may not be entirely seen. For example, it is very hard to see the kidneys in a conventional radiography because the intestines appear in front of them. [15], [16], [11] Moreover, as there are many values of (typically one for each point of the scanned part of the body), it is not possible to calculate their values with one singe measure. However, if measures of the same plane by many different directions are made, all the coefficients may be calculated, and that is what CT does. As Figure 4 shows, a narrow X-ray beam that is produced by the source in the direction of a detector, which means that only a narrow slice of the body is imaged and the value of intensity recorded by the detector depends on all the material crossed by the X-ray in its way. That is the reason why it is called tomography it derives from the Greek tomos which means to cut or section. Many data of X-ray transmission through a plane of an object (an organ or a party of the body) from several directions are recorded and are then used to reconstruct the object by signal processing techniques. These techniques will be discussed later in this monograph (Section 6). The tightly colli mated X-ray beam ensures that no significant scatter is present in order to assure a low signal-to-noise ratio (SNR), a necessary premise to obtain a faithful image of the scanned object. For that reason, unlike conventional tomography, in CT, patients structures located outside the area that is being imaged do not interfere. [17], [9], [12] 5. Instrumentation The X-ray system is composed by an X-ray source, collimators, detectors and a data-acquisition system (DAS). X-ray source is undoubtedly the most important part, because it is what determines the quality of the image. [10], [8] 5.1 The X-ray source The basis of the X-ray source (called X-ray tube) is to accelerate a beam of electrons between two electrodes against a metal target and is shown in Figure 5. The cathode is a coiled tungsten filament, which is crossed by a current which causes the filament to heat up. At high temperatures (2220 °C), the tungsten releases electrons, a process called thermionic emission. A 15 to 150 kV potential difference is applied between the cathode and the anode, which forces the released electrons to accelerate towards the anode. [10] When the electrons hit the anode, they produce X-rays by two ways. On the one hand, when an electron passes near the tungsten nucleus, it is deflected by an attractive electric force (because the nucleus is positively charged and the electron has a negative charge) and loses part of their energy as X-rays. As there are an enormous number of possible interactions and each one leads to a partial loss of kinetic energy, the produced X-rays have a great range of energies, as Figure 5 shows. This process is called bremsstrahlung (i.e. braking radiation). On the other hand, if an electron from the cathode hits and penetrates an atom of the anode, it can collide with an inner electron of it, causing the electron to be ejected and the atom to have a hole, which is filled by an outer electron. The difference of binding energy of these two electrons is released as an X-ray. This process is called characteristic radiation, because its energy depends on the binding energy of the electrons, which is characteristic of a given material. [10], [9], [15] The tube current represents the number of electrons that pass from the cathode to the anode per unit of time. Typical values for CT are from 200 up to 1000 mA. The potential difference between the electrodes is generally of 120 kV, which produces an energy spectrum ranging from 30 to 120 keV. The tube output is the product between the tube current and the voltage between the electrodes and it is desired to have high values because that permits a shorter scan time, which reduces the artifacts due to movement (such as for heart scans). [10], [8] Production of X-rays in these tubes is an inefficient process and most of the power supplied to the tube is converted in heating of the anode. So, a heat exchanger is needed to cool the tube. This heat exchanger is placed on the rotating gantry. Spiral CT in particular requires high cooling rates of the X-ray tube and high heat storage capacity. [8] 5.2 Collimators The electron beam released from the source is a dispersed beam, normally larger than the desired field-of-view (FOV) of the image. Usually, the fan beam width is set for 1 to 10 mm (although recent CT scanner allow submilimetric precision), with determines the width of the imaged slice. The collimator is placed between the source and the patient and is composed by lead sheets to restrict the beam just to the required directions. An X-ray beam larger than the FOV leads to a larger number of X-rays emitted than the ones needed to the scan and that has two problems: the radiation dose given to the patient is increased unnecessarily; and the number of Compton-scattered radiation increases. [10], [8] 5.3 Antiscatter grids An ideal CT system only with primary radiation (x-rays emitted from the source) reaching the detector does not exist and Compton scatter is always present. As this scatter is randomly distributed and has no useful information about the distribution of density of the scanned object, it just contributes to the reduction of image contrast and should be minimized to the maximum. This, because unlike photoelectric effect, Compton effect has a low contrast between tissues. As referred above, collimators are useful to limit the X-ray beam to the FOV. However, even with a collimator, 50% to 90% of the radiation that reaches the detector is secondary radiation. To reduce the Compton scatter, antiscatter grids can be placed between the detector and the patient. [10] An antiscatter grid consists of strips of sheets oriented parallel to the primary radiation direction combined with a support of aluminum, which drastically reduces the scatter radiation that has not the direction of the primary one, as illustrated in Figure 6. In order to not lower the image quality because of the grid shade, the strips should be narrow. There is, however, a tradeoff between the reduction of scatter radiation (that improve the image contrast) and the dose that must be given to the patient to have the same number of detected X-rays. [10] 5.4 Detectors At the beginning, single-slice CT scanners with just one source and one detector were used. However, these took much time to acquire an image, reason why the evolution brought us single-source, multiple-detector machinery and multislice systems. The third and fourth generations added a wider X-ray fan beam and a larger number of detectors to the gantry (typically from 512 to 768), which permitted to acquire more information in a smaller time. The detectors used in CT must be highly efficient to minimize the dose given to the patient, have a large dynamic range and be very stable over the time and over temperature variations inside the gantry. Three factors contribute to overall efficiency: geometric efficiency (fraction of the total area of detector that is sensitive to radiation), quantum efficiency (the fraction of incident X-rays that is absorbed to contribute to signal) and conversion efficiency (the ability to convert the absorbed X-rays into electrical signal). These detectors can be of two types (shown in Figure 7): solid-state detectors or gas ionization detectors. Solid-state detectors consist of an array of scintillating crystals and photodiodes, while gas ionization detectors consist of an array of compressed gas chambers to which is applied a high voltage to gather ions produced by radiation in inside the chamber. The gas is kept under a high pressure, to maximize interactions between X-rays and gas molecules, which produce electro-ion pairs. [10], [8] 5.5 Data-Acquisition System The transmitted fraction of the incident X-ray intensity (I/I0 in equation 1) can be as small as 10-4, reason why DAS must be very accurate over a great range. The role of DAS is to acquire these data and then encode it into digital values and transmit these to computers for reconstruction to begin. DAS make use of many electronic components, such as precision preamplifiers, current-to-voltage converters, analog integrators, multiplexers and analog-to-digital converters. The logarithmic step needed in equation 3 to get the values of  µi can be performed with an analog logarithmic amplifier. Data transfer is a crucial step to assure speed to the whole process and used to be done by direct connection between DAS and the computer. However, with the appearance of rotating scanners in third and fourth generations, these transfer rate, which is as high as 10 Mbytes/s is now accomplished by optical transmitters placed on the rotating gantry that send information to fixed optical receivers. [8] 5.6 Computer system The data acquisition of the projections, the reconstruction of the signal, the display of the reconstructed data and the manipulation of tomographic images is possible by computer systems used to control the hardware. Current systems consist of 12 processors which achieve 200 MFLOPS (million floating-point operations per second) and can reconstruct an image of 10241024 pixels in less than 5 seconds. [8] 6. Signal Processing and Analyzing Techniques As data are acquired in several directions (e.g. with increments of 1 ° or even less) and each direction is split in several distinct points (e.g. 160 or more), at least 28 800 points are stored, which means that there must be efficient mathematical and computational techniques to analyze all this information. A square matrix representing a 2-Dimensional map of the variation of X-ray absorption with the position is then reconstructed. There are four major techniques to analyze these data, which we will discuss subsequently. [12] 6.1 Simultaneous linear equations As it was referred above (Section 4), there is a measure of for each pixel, which means that modern CT scanners deal with 1 048 576 points for each slice (nowadays the matrixes used are 10241024). As a result, to generate the image of one single slice, a system of at least 1 048 576 equations must be solved (one equation for each unknown variable), which means that this technique is totally unusable. In fact, imagine that in 1967, Hounsfield built the first CT scanner, which took 9 days to acquire the data of a single slice and 21 hours to compute the equations (and by the time, the matrix had only 28 000 entries). Besides, nowadays CT scanners acquire about 50% more measures than it would be needed in order to reduce noise and artifacts, which would require even more computational resources. [16], [11], [8] 6.2 Iterative These techniques try to calculate the final image by small adjustments based on the acquired measures. Three major variations of this method can be found: Algebraic Reconstruction Technique (ART), Simultaneous Iterative Reconstruction Technique (SIRT) and Iterative Least-Squares Technique (ILST). These variations differ only in the way corrections are made: ray-by-ray, pixel-by-pixel or the entire data simultaneously, respectively. In ART as an example, data of one angular position are divided into equally spaced elements along each ray. Then, these data are compared with analogous data from another angular position and the differences between X-ray attenuation are added equally to the fitting elements. Basically, for each measure, the system tries to found out how each pixel value can be modified to agree with the particular measure that is being analyzed. In order to adjust measures with pixel values, if the sum of the entries along one direction is lower than the experimental measure for that direction, all the pixels are increased. Otherwise, if the sum of the entries is higher than the measured attenuation, pixels are decreased in value. By repeating this iterative cycle, we will progressively decrease the error in pixels, until we get an accurate image. ART was used in the first commercial scanner in 1972, but it is no longer used because iterative methods are usually slow. Besides, this method implies th at all data must be acquired before the reconstruction begins. [9], [16] 6.3 Filtered backprojection Backprojection is a formal mathematical technique that reconstructs the image based only on the projection of the object onto image planes in different directions. Each direction is given the same weight and the overall linear attenuation coefficient is generated by the sum of attenuation in each X-ray path that intersects the object from different angular positions. In a simpler manner, backprojection can be constructed by smearing each objects view back trough the image plane in the direction it was registered. When this processed is finished for all the elements of the anatomic section, one obtains a merged image of the linear attenuation coefficients, which is itself a crude reconstruction of the scanned object. An illustration of this technique is represented in Figure 8. By its analysis, it is also clear that the final image is blurred, which means that this technique needs a little improvement, which is given by filtered backprojection. [12], [9], [16] Filtered backprojection is therefore used to correct the blurring resultant from simple backprojection. It consists of applying a filter kernel to each of the 1-Dimensional projections of the object. That is done by convolving a deblurring function with the X-ray transmission data before they are projected. The filter removes from data the frequencies of the X-ray responsible for most of the blurring. As we can see in Figure 8, the filter has two significant effects. On the one hand, it levels the top of the pulse, making the signal uniform within it. On the other hand, it negatively spikes the sides of the pulse, so these negative neighborhoods will neutralize the blurring effect. As a result, the image produced by this technique is consistent with the scanned object, if an infinite number of views and an infinite number of points per view are acquired. [16], [9] Compared with the two previous methods this process has also the advantage that reconstruction can begins at the same time that data are being acquired and that is one of the reasons why it is one of the most popular methods nowadays. [9] 6.4 Fourier reconstruction The last signal processing technique that will be discussed in this monograph is the Fourier reconstruction which consists of analyzing data in the frequency domain instead of the spatial domain. For this, one takes each angular orientation of the X-ray attenuation pattern and decomposes it on its frequency components. In the frequency domain, the scanned image is seen as a 2-Dimensional grid, over which we place a dark line for the spectrum of each view, as Figure 9 shows. To reconstruct the image, one has to take the 1-Dimensional Fast Fourier Transform (FFT). Then, according to the Fourier Slice Theorem, each views spectrum is identical to the values of one line (slice) through the image spectrum, assuring that, in the grid, each view has the same angle that was originally acquired. Finally, the inverse FFT of the image spectrum is used to achieve a reconstruction of the scanned object. 7. Data Display As it was said earlier (Section 6), linear attenuation coefficients give us a crude image of the object. In fact, they can be expressed in dB/cm, but as they are dependent on the incident radiation energy, CT scanning does not use the attenuation coefficients to represent the image, but instead it uses integer numbers called CT numbers. These are occasionally, but unofficially, called Hounsfield units and have the following relation with the linear attenuation coefficients: where  µ is the linear attenuation coefficient of each pixel and  µw is the linear attenuation coefficient of water. This CT number depends clearly on the medium. For human applications, we may consider that CT number varies from -1000 for air and 1000 for bone, with CT number of 0 for water, as it is easily seen from equation 5. [9], [13], [4], [12] The CT numbers of the scanned object are then presented on the monitor as a grey scale. As shown in Figure 10, CT numbers have a large range and as human eye cannot distinguish so many types of grays, it is usually used a window to show a smaller range of CT numbers, depending on what it is desired to see. The Window Width (WW) identifies the range of CT numbers and consequently alters the contrast (as Figures 11 and 12 show), whereas Window Level (WL) sets the centre of the window and, therefore, select which structures are seen. The lowest CT number of the window, which corresponds to the lowest density tissue, is represented in black and the highest Ct number (highest density tissue) is represented in white. 8. Radiation Dose As it can easily be understood, radiation dose given to the patient is dependent on the resolution of the scanner and its contrast, as well as

Shakespeare’s Comedy of Errors Essay -- essays research papers

Shakespeare’s Comedy of Errors Comedy of Errors is one of Shakespeare’s first plays. The minor characters, in the play, Egeon and the Duke, set up the framework of the play. Egeon, at the request of the Duke, describes his adventures and relates his life story. This provides the history of The Comedy of Errors, and helps keep track of the confusion, which unfolds during the play. There are several themes that Shakespeare uses which are only loosely related to the actual comedy. The conflicts between burden and freedom, rule and compassion, loss and rebirth all form a critical undertone within the play. There is also the serious effect time. Shakespeare requires that all the action end at five o'clock, the time of Egeon's execution, Antipholus of Syracuse's meeting with the merchant, and the moment when Angelo must pay the Second Merchant his money. There are also several coercions within the play. The comedy opens with Egeon unintentionally breaking the law, for which he is sentenced to death. In addition to this very real danger of death, there is also the risk that the play will end too soon. At various times the reader could assume the characters are close to revealing the entire plot and ending the play. These occur when Antipholus has the chance to demand payment from his father at the beginning, and also when both Dromios are on opposite sides of the door at Adriana's house. The characters are meant to gain knowledge of something. For instance, the Duke claims th...

Cultural Diversity in Organizations Essay

â€Å"Diversity† has arrived as a descriptive word for the American lifestyle in the modern world. With increasing immigration of people from many countries, many races, and many cultural backgrounds to the United States, the country has become a nest of diversity. Several factors shape the fact that the workforce is becoming increasingly culturally diverse: women represent an increasing percentage in organizations; the difference in age is becoming more evident on all levels; due to continuously changing demands organizations are employing more and more people with diverse professional and specialist backgrounds; there is a growing number of immigrants having different customs, religions and cultures and finally, the ongoing globalization is causing an influx of a large number of expatriates, who comes from various countries in the world, also contributing with different values and cultures. This increasing cultural diversity is both an opportunity and a challenge. Diversity brings with it a wide range of creativity and fresh thinking into the system. Diversity is here, in the population, in the workforce and in the marketplace. Racism, discrimination in the workplace, social stratification, and conflicts in social lifestyles are all negative byproducts of diversity. Thus cultural diversity in America is a highly debated issue because of the numerous problems arising due to it. One of the most serious and explosive issues in the United States today is meeting the business goals within an environment of multicultural diversity. When companies fail to create a culture of diversity and inclusion effectively, the costs can be high – costs arising due to ‘diversity training† and settlement of discrimination lawsuits. Many well-known companies have spent millions of dollars on â€Å"diversity training,† after settling discrimination lawsuits totaling hundreds of millions of dollars. Moreover, diversity also raises issues of interpersonal relations and communications among employees. This fact is underlined by increasing discrimination and class action lawsuits. Diversity impacts every person, every project, and every transaction in today’s business world. Some companies approach it in terms of the noticeable differences among people. What many fail to realize is that diversity is really about personal interaction and emotions, and creating a corporate culture that welcomes all kinds of differences. Managing Diversity: Managing diversity is all about approaching the issue proactively as a business opportunity. There needs to be a culture of diversity within the organization. One of the major obstacles in managing diversity is that many companies view diversity as a problem that needs to be solved. They just take a reactive approach. Supposing there is a lawsuit brought under the Equal Employment Opportunity Act, they just take an initiative that would solve the problem in the short run. Though this approach seems to be successful, in the long run, there is likely to be no impact on the corporate culture in a positive way. Such reactive approaches can negatively impact the workforce morale as they don’t appear to be a genuine commitment to diversity. The path to diversity is not always an easy one. One of the most common obstacles is resentment from white male managers who see diversity as threatening to them. â€Å"Since diversity is typically framed to be about white women and people of color, the focus is rarely on examining what it means to be white and male,† say Bill Proudman and Michael Welp, Partners at White Men as Full Diversity Partners LLC, a consulting firm based in Portland, Oregon. â€Å"White men, and sometimes others, thus conclude that diversity is not about them† (Goffney, 2005) Another obstacle that can arise in a multicultural business environment is resistance to change. When new diversity programs are introduced, it is essential that the employees view it as a genuine effort. Hence, these diversity programs should be tailored to meet the needs of the company’s workforce and integrated into the daily environment. Any diversity initiative should be tied to the company’s bottom line. Even though top management may make the commitment to diversity, if the initiative is not tied explicitly to the company’s bottom line, it does not become a priority for middle managers. The diversity initiative should be integrated into the tools and processes they use to manage employees, including orientation, training and education, and interpersonal communication. If not, existing employees will not accept the diversity initiative and new employees are likely to get disillusioned with a taste of it. Top management must ensure that the commitment to diversity has buy-in at all levels of the organization by making diversity an integral part of company success. Yet another obstacle to managing diversity is that the diversity initiatives might be restricted to training alone and is left as an ‘HR issue†. This narrow focus results relegation of diversity to a single department and companies thus miss out on opportunities to improve and integrate the diversity initiative into other areas of the company. Any corporate initiative should be feedback based, dynamic and flexible. Else, there is the danger that the initiative will remain static. Too often diversity initiatives begin and end with the first efforts undertaken. Diversity and inclusion are part of company culture, and like the culture, diversity must continue to evolve (Adams and Ruch, 2006). Managing all these obstacles require the ability to value a diverse world. This means there should be individual assessment of beliefs about work values. People from differing backgrounds having different experiences bring to work the biases and â€Å"veils† as well as the strengths that arise out of cultural differences. To work effectively with persons from diverse backgrounds, it is necessary to understand others– people from other racial, ethnic and cultural heritages, and people whose values, beliefs and experience are different. This involves learning to recognize when new competencies are needed, knowing how to develop the requisite new competencies, and implementing the competencies effectively. Companies need to assess their state of diversity: What is the state of diversity in our company? Are we making the most of diversity? Do we speak with one voice with respect to diversity? Companies that ask these questions on a continual basis, set strategic goals, measure their progress and evolve their programs in sync with their overall organizational change will be the ones to leverage the full potential of diversity (Adams and Ruch, 2006). Individual Reactions to Diversity: Diversity may be viewed positively or negatively depending on the individual reaction to diversity. In a culturally diverse workplace, there is likely to be prejudice, stereotyping and discrimination. This is because of self-fulfilling prophecies. The perceiver develops false belief about a person from a different cultural background. He then treats the person in a manner consistent with that false belief. Ultimately, the person responds to the treatment in such a way to confirm the originally false belief. Other negative reactions of individuals to diversity may include: tension among staff, distrust of anything new, gossip and rumor, open hostility or bullying, absenteeism, tarnishing of the agency’s reputation, low staff retention rates, lack of response to customers and falling standards of service quality (NSW, 2006). In the positive sense, diversity that brings with it community language skills and cultural competencies can be seen as valuable assets to an agency (MSASS, 2006). Customer service improves when employees are able to tackle customers from a range of backgrounds. When employees are encouraged to learn from one another, their skills and knowledge are also enhanced. Diversity can reduce skill shortages at specific times. In a business, diversity gives the advantage of utilizing the language, international expertise and cultural knowledge of staff to identify successful export opportunities. When employees are encouraged to work in their areas of strength and capability, they are happier, more productive and more likely to stay with the agency. Productive diversity is based on the concept that there are potential economic benefits to be gained from valuing different experience, perspectives, skills and the cross-transfer and integration of these into the agency and local economy. Productive diversity makes good business sense in an environment where local diversity and global interconnectedness play a critical economic role (Muhr, 2006). Diversity effects on groups and teams: In the context of working in groups or teams, diversity seems to cause contrasting goals, miscommunication or inter-group anxiety, thereby prohibiting teamwork creativity. Miscommunication and the lack of a common language make it difficult for team members to engage in an exchange of ideas and questions, an exchange, which is essential for effective teamwork (Nahapiet & Ghoshal, 1998). If individuals carry out negative stereotyping of outgroups it can prevent them from trusting and engaging with others and can threaten communication patterns within organizations. This is mainly due to a lack of common context and language usage. Anxiety in the team occurs when people identify themselves as placed among people belonging to different diversity categories. Thus, diversity will in this situation make it difficult for the individuals to identify with the team, since there is no unified perception of what values the team represents (Muhr, 2006). In a diverse work team, the values and perceptions of different diversity categories may be contrasting or even mutually exclusive, which is likely to bring about incongruence in goals. Incongruence in goals can limit communication, which is fundamental to the creation of interpersonal relationships and trust. Furthermore, goal incongruence may also prevent individuals from sharing and combining knowledge all together, if they are not able to reach agreement on common goals for pursuing such knowledge processes (Muhr, 2006). On the positive side, it has been shown that diversity in fact improves creativity by promoting variations, thinking out of the box and avoiding ‘groupthink’. Several analyses have shown that teams made up of people with different cultural and educational backgrounds, different personalities, different professional backgrounds and different skills are potentially more creative and innovative than relatively homogeneous teams. This is because diversity creates variations – variations in perceptions, values, ideas, opinions, and methods, which are highly essential for developing a stimulating creative environment (Mohr, 2006). Conclusion: In the global economy today, most companies operate globally. Diversity of thought, culture, geography, race, and gender enables companies to deliver the best solutions to their customers and markets. Diversity pays off both internally and externally. A company that embraces diversity can offer a challenging and creative work environment, and as a result, can attract and retain top talent with diverse backgrounds. There is also a connection between diversity and increased productivity. Diversity also fosters organizational creativity. But despite these benefits of diversity, work teams will not truly benefit from diversity unless sufficient communication, trust and openness are nurtured in the organizational climate. The powerful advantage of embracing diversity in organizations is best brought out by the words of Ted Childs, IBM’s vice president of global workforce diversity. In a recent issue of Fast Company magazine, in a feature article was entitled: â€Å"Difference is Power†, Ted Childs suggests that, â€Å"No matter who you are, you’re going to have to work with people who are different from you. You’re going to have to sell to people who are different from you, and buy from people who are different from you, and manage people who are different from you. This is how [companies] do business. If it’s (diversity) not your destination, you should get off the plane now† (Meisner, 2006). Bibliography: Adams, Brandon and Ruch, Will (2006).
