Lucy (AL 288) Australopithecus Skeleton from Ethiopia

Lucy is the name of the nearly complete skeleton of an Australopithecus afarensis. She was the first nearly complete skeleton recovered for the species, found in 1974 at the Afar Locality (AL) 228, a site in the Hadar archaeological region on the Afar Triangle of Ethiopia. Lucy is about 3.18 million years old and is called Denkenesh in Amharic, the language of the local people. Lucy is not the only early example of A. afarensis found at Hadar: many more A. afarensis hominids were found at the site and the nearby AL-333. To date, over 400 A. afarensis skeletons or partial skeletons have been found in the Hadar region from about a half-dozen sites. Two hundred sixteen of them were found at AL 333; together with Al-288 are referred to as the First Family, and they all date between 3.7 and 3.0 million years ago. What Scientists Have Learned About Lucy and Her Family The numbers of available specimens of A. afarensis from Hadar (including over 30 crania) have allowed continuing scholarship in several regions concerning Lucy and her family. These issues have included terrestrial bipedal locomotion; the expression of sexual dimorphism and how body size shapes human behavior; and the paleoenvironment in which A. afarensis lived and thrived. Lucys post-cranium skeleton expresses multiple features related to habitual striding bipedalism, including elements of Lucys spine, legs, knees, feet, and pelvis. Recent research has shown that she didnt move in ​the  same way as humans do, nor was she simply a terrestrial being. ​A. afarensis may well have still been adapted to live and work in trees at least part-time. Some recent research (see Chene et al) also suggests the shape of the females pelves was closer to modern humans and less similar to the great apes.d less similar to the great apes. A. afarensis lived in the same region for over 700,000 years, and during that time, the climate changed several times, from arid to moist, from open spaces to closed forests and back again. Yet, A. afarensis persisted, adapting to those changes without requiring major physical changes. Sexual Dimorphism Debate Significant sexual dimorphism; that female animal bodies and teeth are significantly smaller than males--is typically found in species which have intense male to male competition. A. afarensis possesses a degree of postcranial skeletal size dimorphism matched or exceeded only by the great apes, including orangutans and gorillas. However, A. afarensis teeth are not significantly different between males and females. Modern humans, by comparison, have low levels of male-male competition, and male and female teeth and body size are far more similar. The peculiarity of that is still debated: teeth size reduction may be the result of adapting to a different diet, rather than a signal of less male-to-male physical aggression. Lucys History The central Afar basin was first surveyed by Maurice Taieb in the 1960s; and in 1973, Taieb, Donald Johanson and Yves Coppens formed the International Afar Research Expedition to begin an extensive exploration of the region. Partial hominin fossils were discovered in Afar in 1973, and the nearly complete Lucy was discovered in 1974. AL 333 was discovered in 1975. Laetoli was discovered in the 1930s, and the famous footprints discovered in 1978. Various dating measures have been used on the Hadar fossils, including Potassium/Argon (K/AR) and geochemical analysis of the volcanic tuffs, and currently, scholars have tightened the range to between 3.7 and 3.0 million years ago. The species was defined, using Hadar and A. afarensis specimens from Laetoli in Tanzania, in 1978. Lucys Significance Lucy and her familys discovery and investigation remodeled physical anthropology, making it a much more rich and nuanced field than before, partly because the science changed, but also because for the first time, scientists had an adequate database to investigate all the issues around her. In addition, and this is a personal note, I think one of the most significant things about Lucy is that Donald Johanson and Edey Maitland wrote and published a popular science book about her. The book called Lucy, the Beginnings of Humankind made the scientific chase for the human ancestors accessible to the public.   Sources Chene G, Lamblin G, Lebail-Carval K, Chabert P, Marà ¨s P, Coppens Y, and Mellier G. 2015.

Business Planning Start-up Changes

Question: What was included in the business plans? What were the good and bad aspects? Which one section of the business plan do you think is most important? If you were in charge of business planning how would you improve these business plan? The learning are: Apply understanding of the inter-relationships of key business functions Critically evaluate the value to the firm of proposed investment projects Apply understanding of the impact of ICT skills in formulating a business plan Answer: What was included in the business plans? From years of working experience, it has been found that there are mainly three types of business plans used by various organizations. They are such as startup business plan (business plan of Amazon), standardize business plan (used by Samsung) and lean business plan (Xeroxs lean six sigma business model). There are various aspects included in these business plans. They are mentioned below: Startup business plan of Amazon According to Westwood (2013), the business plan that is used to initiate a business is known as startup business plan. Amazons startup business plan includes factors like startup states of the business, startup cost, and milestones. In addition, the legal expenses incurred from graphics, logo, website designing and fixing up the store is also included in it (Wentzensen and Wacholder 2013). It also includes the assets that are required for business. They are such as vehicles, inventory, office furniture and equipment (Nattrass and Altomare 2013). Samsungs Standardize business plan As Manyika et al. (2013) stated that, most of the standardize business plan starts with a summary. It includes different sections related with the company such as product or service it sells, target market, development of goals and milestones, management team and forecasting. As (Zikmund et al. 2013) mentioned that there are different tactics included in the standardize business plan of the company Samsung. They are such as management plan, product plan, financial projection and marketing plan. The financial projection includes three major essentials. They are like balance sheet, profit loss, and cash flow. Samsungs Standardize business plan also adds personal spending in every department. As Kwong et al. (2012) stated that, the key behind the success of Samsungs standardize business plan is the communication between different departments. The company has used ICT technology efficiently to improve communication between different departments. Xeroxs lean six-sigma business model It has been found that the company Xerox uses lean Six Sigma business plan in order to manage tactics, deadlines, strategy, cash flow, and activities. As Blank (2013) stated that, there four major elements are included in the lean Six Sigma business plan of the company Xerox. They are mentioned below: Development of strategy The target market for the organization is defined. In addition long-term business goals for the organization are developed along with the business offerings (Barrow et al. 2012). Development of tactics to execute those strategies As Mullins (2012) mentioned that, this plan includes different marketing decisions related to marketing, pricing, promotion, website, channels, social media, and advertising. All the product and service related tactics are also developed at this stage. They are such as launching dates, packaging, and development of new versions of products. Specification development It includes a list of task responsibilities, assumptions, milestones, the number of tracks and objective measurements (Mullins 2012). Significant numbers In this section, various essential numbers are included. They are such as spending budget, sales forecast for the company and cash flow. What were the good and bad aspects? There are some positive and negatives aspects of all these three business plans have been analyzed. They are discussed below in the table: Business plans Good aspects Bad aspects Startup business plan of Amazon Startup business plan of Amazon breaks out the steps and requirements to initiate a business. This type of plan is good for deciding whether a business is worth perusing or not (Zikmund et al. 2013). With the increase of business, necessary additions can be done in this business plan. This business plan is able to provide a preliminary analysis of the pricing, costs and the probable expenses of Amazon (Westwood 2013). Startup business plan of Amazon provides a preliminary idea about business expenses for websites, graphics, signage, product launch and service expenses. All these decisions are made on educated guesses. However, the business environment is changing every day. For this reason, the actual expenses can differ from the predicted expenses (Mullins 2012). It can reduce the efficiency of business operation for company Amazon. Samsungs Standardize business plan Samsungs Standardize business plan is able to meet all the business needs for prospective investors, partners and employees. The standard business plan has provides a projected cash flow for the company Samsung. Which always become beneficial for the company. As Blank (2013) stated that, a business could temporarily survive without benefit. However, it still needs cash to pay the bills. Since profit alone doesn't guarantee cash in bank, project cash flow is highly significant. Inadequate research work can decrease the effectiveness of a Standardize business plan. For example, Samsung needs to make ample research work on customer's purchasing behavior, competitor positioning, and overall market trends before developing a product (Manyika et al. 2013). From personal experience, it has been found that most of the business plans are developed based on assumptions. For this most of the other companies who standardized business model are not becoming successful (Samsung is exception). Xeroxs lean six-sigma business model It has already contributed hundreds of millions of Dollars in cost savings, cost and revenue of the company Xerox. Lean business plan is used to manage dates, tactics, business strategy, deadlines and cash flows for the company Xerox in an efficient manner. The company has generated $ 150 economic profit in the year of 2004 by using this model (Barrow et al. 2012). Blank (2013) stated that, this business plan is more efficient than standard business plan. This business plan helps to set deadline and milestones so that a project team can increase its speed to meet the organizational objectives. Lean business plan is more complicated in a structure in comparison to Standardize business plan (Manyika et al. 2013). Which one section of the business plan do you think is most important? From personal working experience; it has been found that maintaining inter-relationship of various business function is the most important part of all three business plans. It has been concluded that most of the businesses have five core business processes. They are such as business operations, product and service development marketing and sales functions, distribution and after sales services (Manyika et al. 2013). In addition, three support business processes characterize the firm. They are such as general management and firm infrastructure, human resource management and technology and process development. A business plan must try to develop effective interrelationship among different business functions. For example, business operation is the activity that that can transform inputs into final goods or services. A business plan should develop effective corporate governance strategies to support business operation of a company (Blank 2013). It includes finance, legal aspects, infrastructure, management and government relations. In order to improve product and service development, a company like Samsung needs to manage its budget effectively. With the help of a lean business plan, different tactics related to marketing, pricing, promotion, website, channels, social media, and advertising can be taken. All the product and service related tactics are also developed at this stage. They are such as launching dates, packaging, and development of new versions of products. In order to improve after sales service, a company must initiate some specific activities. It may include help-desk service, call center service, training, and customer support. All these aspects also need to be added in a business plan (Barrow et al. 2012). The most important aspect of a successful business is to develop effective communication between different departments and functions. A company like Xerox must use Enterprise Resource Planning (ERP) programs to coordinate information in every section of the business. As Manyika et al. (2013) stated that, a company like Amazon needs to use common database and shared management tools to improve the flow of information. If you were in charge of business planning how would you improve these business plans? As the in charge of the business plan, certain strategies will be implemented to improve these business plans. For example, ICT (Information and Communication Technology) skills can be adopted to formulate a business plan. 1) ICT enables the possible use of different technologies such as spreadsheets, database, presentation software, SMS, and the Internet. As Goebel (2013) stated that, these technologies could help to develop effective communication between various departments of business. 2) It can help to develop strategies to select proper hardware and software to meet the business needs. 3) ICT can help to use e-commerce technology in business. 4) Cloud storage technology can be used to keep record, store and retrieve private data from employees and employers There are some particular benefits that ICT technology can provide in business. They are mentioned below: Efficient information storage: With the help of ICT technology, huge quantity of data can be stored. Easy retrieval of information: Data can easily be manipulated and accessed with the help of ICT. As Hellang et al. (2013) stated that ICT is useful for business as it is able to provide specific information Efficiency of business operation: Use of computer can save the time of record keeping. In addition, essential information can easily be transferred from one department to another department of a company. Global reach: Using internet connection, a company can expand its market globally (Goebel 2013). User-friendly: ICT technology is highly user-friendly. It provides "prompts" or "what to do menus" from which a particular action can be selected (Christensen and Raynor 2013). Accessibility: As Goebel (2013) stated that, with the help of ICT technology data can be accessed from remote locations. Speed: Computers can perform complex calculations within seconds. It can improve the business operation of a company (Hellang et al. 2013). Cost effectiveness It has been a fund that the price of software and hardware id dropping significantly over years (Manyika et al. 2013). Hence, companies can take this opportunity and use ICT technology to improve their business. Reference list Barrow, C., Barrow, P. and Brown, R., 2012.The business plan workbook.

The Difference Between Emigrate and Immigrate

The Difference Between Emigrate and Immigrate These two verbs have similar meanings, but they differ in point of view.Emigrate means to leave one country to settle in another. Immigrate means to settle in a country where one isnt a native. ​Emigrate stresses leaving; ​immigrate stresses arriving. For example, from the point of view of the British, you emigrate when you leave England to settle in Canada. From the point of view of the Canadians, you have immigrated to Canada and are considered an immigrant. Emigrate describes the move relative to the place of departure.

From Empiricism to Postmodernism Essay Example | Topics and Well Written Essays - 2250 words

From Empiricism to Postmodernism - Essay Example The essay "From Empiricism to Postmodernism" states Empiricism and Postmodernism. The nature of knowledge has evolved throughout history. During the modern period, that is â€Å"since the 17th century scientific revolution and the Enlightenment, we have assumed there is a single objective reality, and science and reason offer the most effective method of discovering it†. This was highlighted during two modern philosophical traditions, i.e. rationalism and empiricism. Rationalism, which began with Rene Descartes, claimed that knowledge stems from reason alone. However, by the time John Locke came into the scene, the nature of knowledge began to shift towards the empiricism. This was at its peak with the empiricist, David Hume. Contrary to rationalism, empiricism claims that knowledge stem from our experience alone. What we can know is that which we can perceive and experience through our senses. Nevertheless, despite the contrast between these two traditions, both characterized knowledge as something structured. It both aimed towards an objective truth, which serves as the foundation of all knowledge. However, by the end of the modern era, a new tradition stepped into the scene. This was called postmodernism. Postmodernism, on the other hand, serves as a critique of the modern project. While modernism emphasized on structure, postmodernism emphasized on de-structuralizing knowledge. The new movement implies a shift from the signified to the signifier: and so there is a perpetual detour on the way to a truth. that has lost any status or finality† (Sarup 1993, p.3). Postmodernism deconstructs foundational concepts such as causality, identity, truth and knowledge. Postmodernists attack the view that there is a single unified body of knowledge. Rather, knowledge, for postmodernists, is relative. There is no single truth so to speak but a multiplicity of truths. It argues that â€Å"the human subject does not have a unified consciousness but is structur ed by language† (Sarup 1993, p.3). In this paper, I shall focus on two philosophical traditions that have shaped the way by which we perceive reality, i.e. empiricism and postmodernism. I shall show how these two traditions differ in their epistemological approaches. In doing so, I shall argue that postmodernism does not serve to give us a clear picture of knowledge. Thus, if philosophy, in its epistemological concerns, aims to search for foundations of our knowledge, then so it seems that postmodernism contradicts the very nature of philosophy in its goal to achieve a reliable and foundational theory of knowledge. Therefore, although empiricism relied too much on observable facts, it nevertheless gave us a consistent theory of knowledge, as opposed to the postmodernist epistemological approach. Given the aforementioned background, I shall divide this paper into three main parts. The first part will discuss the empiricist tradition with regards to its epistemological approache s, while the second part will discuss the postmodernist approach. Here, I shall emphasize on the difference between the manner by which both traditions define the nature and acquisition of knowledge. Finally, the third part will be devoted to my analysis regarding the issue at hand. This will serve as my conclusion. In this final section, I shall give my argument on what I believe is the more consistent and reliable framework for epistemology. In doing so, I shall defend the empiricist view on epistemology as that which upholds rather then rejects the nature of philosophy. For, structure is a necessary factor in any theory of knowledge. Postmodernism deconstructs this structure of knowledge that philosophers, since the ancient period have developed. I shall argue that postmodernism dissolves the very nature of knowledge, and this nullifies the nature of philosophy itself. Postmodernism only serves as a critique to empiricism, but it does not suffice to create a reliable framework of a theory of knowledge, that is, of epistemology. Empiricism and Epistemology There are four

Duress Is Not a Defence to Murder Essay Example | Topics and Well Written Essays - 1000 words

Duress Is Not a Defence to Murder - Essay Example The word ‘duress’ can be explained as a compulsion on an accused by a third party to carry out a murder, or else , he might have witnessed a cruel harm, including death from such a third party.This research essay will analyse how duress cannot be claimed as a defence to murder as held in R v Howe with decided other case laws on the subject.Analysis In Attorney-General v Whelan, 2 it was held that duress is a threat with an instant death or grave body injury to the defendant, and if he refuses to carry out the order of a third party and it should be acknowledged as a validation for action, which would else be regarded as a criminal offense.3 In the earlier times, if duress is claimed as a defence, then the prosecution has the duty to prove beyond doubt that the defendant was not indulged in a crime under duress. However, now, the onus to prove the duress defence claims rests with an accused. Duress cannot be successful in case where there is a claim of peril of lesser har m such as damage to assets or false imprisonment. As held in R v Howe, if there is an instant threat of a serious body injury or death, then defence under duress can be claimed for crimes other than murder and treason.4 Under English law, duress as a defence is not available to attempted murder, murder, or any kind of treason. Hence, the crucial issue was whether duress was a valid defence in murder cases. A defendant may claim duress as an excuse that connotes the defendant had been compelled to act under such a harsh danger that precluding from the crime could not rationally be expected.6 Duress by circumstances and duress by threat are differentiated as to the basis of the threat. Duress per minas (by a threat) starts from a human peril while duress by circumstances involves a peril of natural origin. Both threats can qualify as a valid excuse. In DPP for Northern Ireland v Lynch, 7 Lord Simon observed that duress is just a specific usage of the canon of necessity. In this case, it was held by the Lords that defence of duress was available to a collaborator. In this case, the lords observed that where a defendant is left with two alternatives, which are between the peril of death or grave injury, and if he wantonly put an end to life of an innocent, an ordinary individual should think that one naive human life is as precious as that of his family members and in such event, the defendant cannot argue that he is preferring the least significant of the two evils. Likewise, in R v Gotts,8 it was held that duress is not a justification to an attempted slaughter.9 In normal parlance, the courts would not acknowledge a defence of duress when an abnormal injury is made by the defendant .This is known as a test of proportionality as held in R v Howe.10 Likewise, the duress shield can fail if the prosecution is able to demonstrate that the defendant had a chance to avert the threat from the third party by taking timely help from the police, and if the defendant negle cted to do so, the defence of duress would not be successful as held in R v Hasan.11 Lord Bingham in the R v Hasan case viewed that the peril may be to the defendant or to his family or to a known person of the defendant. Hence, peril against the welfare of the defendant’s family, or to his life or to the life of the person known to the defendant, will be an adequate proof of duress.12 In R v Fitzpatrick,13 it was held that a gang member who had been compelled to indulge in murder could not raise a defence of dur

'Discipline & Punish (Foucault, 1975) is not just a history of the Essay

'Discipline & Punish (Foucault, 1975) is not just a history of the emergence of the prison but a history of the emergence of a - Essay Example Thus, Discipline and Punish could be deemed as Foucault’s critique not only on the effectiveness of prison in attaining its key objective—the disciplining of the prisoner by subjecting him to conditions that are marked by extreme surveillance and control—but also on the true reason for the emergence of various social structures today such as the government, school, and other institutions (Mc Gaha, 2000). Precisely, it is Foucault’s belief that such systems had only been created to cater the elite group (which I shall explore in more detail in the next part of the paper) that bolstered his onslaught on the basic foundations of human civilization. Specifically, by recognizing the essence of prison and other social institutions as merely ‘instruments’ used by the elite to maintain and enhance their power in society, Foucault was able to question essentially the possibility of attaining human freedom in modern-day society. In a deeper regard, I co uld surmise that Foucault’s attacks on social structures could be attributed to his anarchistic mindset (though not explicitly revealed in any of the texts) as he clearly disregarded the need for such systems. Therefore, human freedom must be seen as the act of ‘letting one be’ and not ‘following what and how one must be’. His precise bastardization of naturals or ideals (as will be discussed later on) could clearly provide an ideological nexus between his anarchistic mindset and his post-modern orientation. If seen in this context, Foucault’s take on the human essence (for the lack of a better term) is slightly existentialist. In this paper, I like to delve further into Foucault’s Discipline and Punish by dividing the discussion into four parts. The first part shall emphasize on the short history of the penal system, which could be traced back to 17th century. Through this part, I aim to highlight on the fact that the development of th e penal system had shifted the punishment from physical to mental. The second part will be dedicated to reinforcing the concepts of power and control as the main thrust for the creation of modern social institutions. This will infuse the significant role of the elite in the formation of such institutions. The third part shall zero in on Foucault’s conceptualization of human freedom as hardly attainable given the flaws in modern day systems today. By having this part, I am to provide a reasoning that encapsulates Foucault’s socio-political ideologies Evolution of Punishment and the Rise of the Penal System Following the flow of discussion in Discipline and Punish, Foucault opted to start (in a more detailed light) with a detailed discussion on public tortures and executions that transpired during the17th and 18th centuries. Presenting explicitly the execution of the Damiens, Foucault (1976) narrated, â€Å"after these tearings with the pincers, Damiens, who cried out p rofusely, though without swearing, raised his head and looked at himself; the same

Social And Cultural Aspect Of Child Abuse In Punjab

Social And Cultural Aspect Of Child Abuse In Punjab In the article he discussed that children are a very vulnerable sector of our society. Child abuse can occur in every sector of our society, but some children are at a higher risk for abuse. The reason behind the research is to find out what is child abuse and to know the different forms of physical abuses. D.P.Noe said Children are at an increased risk for abuse if they were a product of an unwanted pregnancy, or have parents that are still children themselves. There is an increased risk for child abuse if the parents of a child have history of being abused when they were children. or are have been brought up in a home with domestic violence. Single parents or parents with a drug or alcohol problems put a child at a higher risk for abuse. Certain socioeconomic levels such as children living in poverty place them at a higher risk for abuse. The different types of physical abuses discussed by the author are May present with bruises that are patterned, multiple bruises of different ages, bruising in a non-ambulatory child, burns, and lacerations. The reason behind the research is to know the role of the family life educator that how child abuse can be prevented by the family itself. He said there are different programs to prevent child abuse there are school based programs, Schools are in a unique position to address the child abuse problem through school based programs. School based programs should stress the primary prevention of child abuse by basing content on the cultural forces contributing to abuse. He describe some teaching suggestion in the article which are effective in a family life education program emphasizing the teaching of positive discipline as a primary prevention method for child abuse for example Invite student perspective on the topic of discipline, Invite students to share their feelings with the class. Further more he discussed that what question should be asked by the student and how should they be treated. The role of the teachers. He said equally important is the need to develop activities that will provide students with an opportunity to confront feelings about discipline issues and to learn discipline and guidance strategies that help children develop social competence. The reason behind the research is to know the reason why and how child abuse occur in step families. Evidence from the cases suggests that stepparents are overrepresented among abusers. Jean Giles-Sims and David Finkelhor explained five theories that have been used to explain this presumed relationship. The theories are: social-evolutionary, normative, stress, selection and resource theory. Author also discussed Stepparents and Natural Parents as Perpetrators In Three Types of Child Abuse (physical abuse, sexual abuse and emotional abuse). According to his research step mother conduct more physical and emotional abuse. The social-evolutionary (sometimes referred to as socio-biological) perspective predicts that stepchildren are more likely to be both physically and sexually abused than natural children, using different arguments to explain each type of abuse. According to the normative theory of sexual abuse by stepparents is consistent with a social-evolutionary perspective which ar gues that the justification of incest taboos is to avoid genetic degradation. However, the normative argument does not require a biologically based assumption. In the stress theory it is stated that stepfamilies experience stress, and that stress is related to child abuse. In the selection factor theory author said that it may be that the same factors which make people prone to divorce and remarriage also make them prone to abuse children. It may be that the same factors which make people prone to divorce and remarriage also make them prone to abuse children. Resource theory is the final theoretical approach which explains higher rates of child abuse by stepparents. According to this theory, the more resources a person can command, the more power and authority that person has at his/her disposal to regulate a social system. the reason for conducting this research is to analyse the Ethical dilemmas that are commonly encountered in family sexual abuse cases. In the research the primary ethical problems faced by marital and family therapists working with families in which child sexual abuse is suspected or has occurred are examined. The sexual abuse of children is most frequently perpetrated by males upon females, with stepfather or biological father/daughter molestation being the most commonly reported form of abuse. Kitchener (1984) and Thompson (1990) suggest that the practitioner turn to the following six general ethical principles to guide ethical decision making: autonomy, fidelity, Justice, beneficence, nonmaleficence, and self-interest. These provide a framework for considering the specific ethical dilemmas encountered by family therapists who are confronted with child sexual abuse. Author also discussed the therapeutic treatment of abuse it is recommended that sexual abuse treatment with these fam ilies not be undertaken without specialized training and supervision (Principle .6). The therapist may need to refer the family, a process that can be facilitated by helping the clients understand that this action affirms the therapeutic promise to promote their welfare. Awareness of the meta-ethical principles involved in working with these families can help to identify where principles may conflict. The reason for the study is to identify economic and cultural generative factors of child abuse. There are special circumstances affecting the occurrence of child maltreatment, such as parental youth and inexperience, parental discord and divorce, adoption, and problematic child attributes, which are explored in the research. The evidence for intergenerational transmission of abuse is also examined. The few prospective studies that have used quantitative methods have yielded mixed results, with two (Johannesson, 1974; Sears, 1961) reporting no evidence for an association between corporal punishment and child aggression, and (Lefkowitz, Eron, Walder, Huesmann, 1977 McCord, 1979 Singer, Singer, Rapaczynski, 1984) find a positive association. The reason why parents maltreat their children are parents own background, economic position. Economic factors leads to economic stress, Economic stress generated depression and demoralization in parents, which in turn resulted in marital conflic t and bad parenting-harsh, inconsistent discipline and hostile rejection or non involvement. Divorce is also the reason for the maltreatment of children by parents. Low income and single parents also become the reason for the child abuse. Data obtained from research with non abusive middle-class families. The research also focuses on facets of responsiveness (warmth, reciprocity, attachment) and demanding ness (coer- civeness, confrontation, monitoring, supervision, consistent discipline, corporal punishment) (Maccoby Martin, 1983). Compared to parents from non abusive families, parents from both abusive and neglectful families can be expected to be less responsive and neglectful parents to also be less demanding. The reason for conducting the research is to find the exact relationship between stress and child abuse despite the fact that stress contributes to child abuse. Author discussed three models postulating the influence of stress on child abuse phenomenological model, life change model, and social model. In phenomenological model describe that an early formulation of the stress and child abuse relationship, suggests that abusive behaviour is unleashed by figurative or solid incidents perceived as stressful by adults who are vulnerable to abuse from inadequate upbringings. Stress arises when an incident is judged to be personally threatening. Assessing the threat, including risks to self-esteem and physical comfort, occurs after the individual inventories his or her personal resources for coping. The usefulness of the phenomenological model is limited by its lack of ability to identify unique characteristics of the situation or the abuser. Such constraints as cultural factors, for one, c ontribute to abuse. In the life chain model describe the connection between stress and abuse. This model posits a series of changes in life situation as contributing to the potential to abuse. It also assumes that physical and psychological stress processes are equivalent. The life change model is as follows: C:UsersstudentDesktopaaaaaaaaa.PNG The social model describes another explanation of the connection between child abuse and stress. Child abuse is largely a function of the stresses of poverty, the social model rests on accumulating evidence from child abuse researchers that diminished social or ecological resources accompany poverty and increase child maltreatment among the poor. members of lower socioeconomic groups are exposed to more stressful events than members of higher socioeconomic groups and that the poor are more helpless to the impact of those events. Social isolation is manifest in child abuse. In short phenomenological, life change and social models of stress in child abuse explains that stress in part arises from personal appraisals, cross-sectional life disruptions, and environmental deprivations. This research is done to analyse the different effects of demographic, social, and economic factors on the number of child abuse and there are neglect reports in 18 urban, suburban, and rural counties over a period of 6 years. The analytic portion of this research consists of two parts. The first tests hypotheses about the effect of each independent variable on the dependent variable, child abuse and neglect reports. The model is separately tested for the urban, suburban, and rural counties. The second part uses the independent variables to determine the extent to which the model replicates actual data in each type of county. The time-series approach is used to analyse the growth of child abuse. Eighteen of 58 urban, suburban, and rural counties were selected for analysis. Child labor has become an important discussion topic and that how childrenà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s rights may be protected as globalization has increased so has concern for childrenà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s rights and child labor.. Most societies believe that if children will work they will learn more but conditions that are detrimental to their health is an area of concern. Children who are appreciated by their families are able to learn more an in a less stressful manner compared to those who are not praised and whose work is also not praised. Many conventions have been held by ILO to de motivate those who employ children and force them to work in hazardous conditions. Some international organizations have also been trying to create awareness about childrenà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s rights. In every country organizations are working for rights of child. New institutions are opened to guide the people. UNICEF and various nongovernmental organizations are working to protect Convention on the Rights of the Children and its effective implementation There are several forms of child abuse and the one which has received most concern is the battered child syndrome. There are six main types of abuses that have been discussed including physical abuse and physical neglect. The reason for child abuse could be that as a child the abuser was also maltreated by his parents for not meeting their demands. Such children when marry look for spouses who have been through similar experiences during their child hood. Parents sometimes have unrealistic expectations from their children and when the child is unable to meet these demands the parents become frustrated and become abusive towards the child. Adolescents aged 12 to 17 account for 20% of the abuse and neglect cases. These children can be treated with the help of the family and several different community services. Although the aim of the treatment is to protect the child but it also focuses on the parents. Abusive parents have problems asking for help thus a reporting system can generate better results. Suspected child abuse may be directed by observing a sick or injured child with his parents or by listening to parentà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s explanation of injuries. Parents should be told of places from where they can receive help for parenting their child in a better manner. The emotional aspects of parenting should be incorporated into parental training classes as well as into all other types of parenting education. Family life courses and family planning clinics should inform people of the responsibilities negative along with positive. The American public health association adopted policies to prevent child abuse as a problem which has significant health problems. The cost of child maltreatment has significant and long lasting effects. Cultural acceptance for child abuse is seen in schools in the form of punishments and abuse by parents and neighbors is seen as a problem. Thus measures should be taken to reduce acceptance for child abuse and violence. Coordinated efforts of the public sector and the private sector shall be taken in order to create awareness about the responsibility. Training programs should also be held in order to reduce abuse against children in an effective manner. These programs need funding and support to become more affordable by the society. A conclusion that the article with draws is that those children who have been abused as a child tend to become child or spouse abusers themselves thus research shows that child abuse is directly related to family stress, financial problems and single parenting responsibilities. Child abuse can only be prevented with the help and cooperation of all the sectors private and public including public health, law and order and educational institutes.

Ancient Greece Essay -- Ancient Greece Essays

Ancient Greece GEOGRAPHICAL LOCATION The Ancient Greek civilization was located on today’s Greek land, Ionian Islands, Asia Minor, South Italy, and Sicily. It is surrounded by mountains and in the north by water. The Ionian and the Aegean seas, together with natural islands and bays, gave the Greeks the opportunety to develop their maritime commerce and their rich culture. The mountains, which surrounded Greece, gave us the picture of its political character. From early times, the Greeks lived in independet settlements, and they were isolated from one another.

GREEK’S HISTORY The Greek civilization has made great contributions in many areas to western society. Greeks scientists made revolutionary discoveries in medicine, mathematics, physics and astronomy. They also developed the expression of individuality. Those are only some reasons why the Greek civilization was and still is one of the most important civilizations in the world. TIME PERIODS 1.

Free Essays on Charlse Darwin

Charles Darwin was born in Shrewsbury, England, on February 2, 1809. His father was Robert Waring Darwin, a physician and son of the famous Erasmus Darwin, also a physician, as well as a respected writer and naturalist. His mother was Susannah Wedgewood Darwin. She died when Charles was eight. Charles was educated in the local school, taught by Dr. Samuel Butler. In 1825, he went to Edinburgh to start studying medicine, but he soon realized that he did not have the stomach for it. So he switched to Cambridge, ostensibly to become a clergyman. He was actually more interested in entomology, especially beetles, and in hunting. He graduated from Christ’s College in 1831. It is said that even when he was a young man, he had a patient and open mind, spending many hours collecting specimens of one sort or another and pondering over new ideas. The idea of evolution was very much in the air in those times. It was increasingly clear to naturalists that species change and have been changing for many years. The question was, how did this happen? One of his mentors, John Henslow, encouraged him to apply for the unpaid position of naturalist on a surveying expedition on the now-famous vessel, the Beagle, under the command of Capt. Robert Fitz-Roy. Charles left England for the first time in his life on December 27, 1831. He wouldn’t return until October 2, 1836! Most of the ship’s time was spent surveying the coasts of South America and nearby islands, but it would also visit various Pacific islands, New Zealand, and Australia. It was the Galapagos Islands that most impressed him. There he found that finches had evolved a variety of beaks, each suited to a particular food source. Natural variation had somehow been selected to fit the ecological niches available on the tiny islands. Upon returning, he wrote several books based on his surveys on geology and the plant and animal species he had observed and collected. He also published hi...

In 1825, he went to Edinburgh to start studying medicine, but he soon realized that he did not have the stomach for it. So he switched to Cambridge, ostensibly to become a clergyman. He was actually more interested in entomology, especially beetles, and in hunting. He graduated from Christ’s College in 1831. It is said that even when he was a young man, he had a patient and open mind, spending many hours collecting specimens of one sort or another and pondering over new ideas. The idea of evolution was very much in the air in those times. It was increasingly clear to naturalists that species change and have been changing for many years. The question was, how did this happen? One of his mentors, John Henslow, encouraged him to apply for the unpaid position of naturalist on a surveying expedition on the now-famous vessel, the Beagle, under the command of Capt. Robert Fitz-Roy. Charles left England for the first time in his life on December 27, 1831. He wouldn’t return until October 2, 1836! Most of the ship’s time was spent surveying the coasts of South America and nearby islands, but it would also visit various Pacific islands, New Zealand, and Australia. It was the Galapagos Islands that most impressed him. There he found that finches had evolved a variety of beaks, each suited to a particular food source. Natural variation had somehow been selected to fit the ecological niches available on the tiny islands. Upon returning, he wrote several books based on his surveys on geology and the plant and animal species he had observed and collected. He also published hi...

Democratic Theory Essay Example | Topics and Well Written Essays - 1250 words

Democratic Theory - Essay Example It takes care of subjects related with political pluralism, equality in the wake of law and the right to submit petition for the elected officials. (Young, 2000) It also brings to light different matters pertaining to human rights, civil liberties, a number of varied elements of the civil society and the different institutions working under the auspices of the government of the state. The origin of democracy has come about from the Ancient Greek times. The Ancient Greek political and philosophical thoughts made use of democracy and its different undertakings in their day to day affairs and practice. Plato called democracy as the system of rule by the governed, which summed the whole essence of democracy in its truest sense. The Republics of Ancient India had some instances and traces of civilizations of democracy within their ranks. This was way before the birth of the Buddha. Thus the origins of democracy stretch quite back in time and a number of nations can hold themselves in line with the original basis that was brought forward by this system of government, ruling and indeed legislation. (Przeworski) In its truest meaning, democratic theory is a political philosophy more than anything else. It is a form of government which exists for the people and brought in essence by the people. Democracy calls for competitive elections which are mandatory within such a form of government. What this does is to elect people or office bearers who get the most votes in such an election exercise. These elections bring to light the aspects of freedom of speech, freedom for the press and television and radio as well as a general exercise of law within the very state in which elections are being carried out. (Gabardi, 2001) In the name of democracy, it is significant that the civilian control of the military is kept away as much as possible since this gives rise to military dictatorship regimes and thus intervenes in the smooth political affairs and their

Effect Disorders Have on Adult Neurogenesis Research Paper

Effect Disorders Have on Adult Neurogenesis - Research Paper Example Therefore, neurogenesis normally leads to production of new neuronal cells that serves to provide an additional stock of plasticity to allow the adult brain to adapt to changing environmental cues. This in the end provides the possibility of making stable modifications between the existing neuronal network and its cognitive and emotional functions. Winer, Kohl and Hage present that the generation as well as cell death of a cell of a newly generated tissue, plays a significant role in the development and maintenance of the brain of both adults and embryos. Consequently, any alterations in such processes are normally seen in the presence of a neurodegenerative disease. There are a number of such diseases that that tend to interfere with the proper functioning of the brain and other associated neurological functions. These diseases include Alzheimer’s disease, Schizophrenia, Epilepsy and Depression. This paper seeks to analyze the various effects of that these disorders have on adult neurology. Moreover, the precise effect of each of these disorders will also be highlighted with particular interest on the specific part of the brain the disorders tend to affect. According to Scharfman, in the adult brain neurogenesis usually occurs in three distinct areas, the subventricular zone, the olfactory bulb and the dentate gyrus of the hippocampus. Winer, Kohl and Gage document that disorders that tend to interfere with the proper neurological functioning of the adult brain, are associated with certain genes that play a great part in the development of the disorders. Some of these genes include presenilin, and alpha-synuclein. They tend to have some psychological effect in the modulation of the plasticity of the brain especially on protein membranes and areas with a high concentration of synapses. Additionally, the alpha-synuclein gene also tend to interfere with the synthesis of dopamine, whose synthesis, metabolism, subsequent release or

Read the garduition story and after that answer the 3 question of end of the story - Essay Example Angelou surprises her reader by relating her thoughts during the course of the graduation ceremony. She explains how the white politician takes the stage and insults the students by implying that the only jobs for which blacks are suited is manual labor and sports. The most jarring moment for the reader occurs at the end of the essay when Angelou describes the class singing the Negro National Anthem as a form of protest. 2. The ancient tragedy Angelou is describing is the tragedy of the slave being sold on the dais during the time of slavery in America. Angelou depicts the disgrace of this event. Professor Parsons is on the stage, but just like the slave being sold at auction, â€Å"his eyes said he was no longer with us.† He is detaching himself from the situation just as his ancestors did. Angelou changes the tragedy by relieving the disgrace at the end of the ceremony. Instead of ending in tragedy as the sale of a slave does, the graduation ceremony ends with a note of hope. As Angelou states, â€Å"we were on top again.† 3. Like Angelou, I was involved in an event in school that I greatly anticipated. I was very active in the drama club in high school. We would always put on three plays a year, and each one was a production that took a tremendous amount of effort to create. The technical crew would spend hours after school making sure that the sound and lighting was perfectly timed. The art classes at school would help paint the sets, and various students would build different sets using the tools from the woodworking class. The mothers of all the drama club students would stitch the costumes. I was always a part of the cast, in minor roles and major roles. One year, we chose a particularly difficult production, Alice in Wonderland. The costumes were very elaborate and took months to create. Because of the psychedelic nature of the play, the sets required bright colors and

Manifest Destiny Essay Example for Free

Manifest Destiny Essay The belief in Manifest Destiny, America’s right to expand westward, was popular among the Democratic Party, which paved the path for conflict in U.S. politics. In the 1840’s, Manifest Destiny was used as justification for the annexation of Texas, the war with Mexico, and to acquire portions of Oregon from the British. The debate over whether America really had a manifest destiny to expand all the way west or if it was used as an excuse to acquire more land led to debates in U. S. politics. Advocates of manifest destiny, mostly democratic, argued that the U.S., as a more advanced culture, had a God-given right to expand its borders. They believed the expansion would civilize the West and America’s democratic, cultural, and religious values would benefit the Native Americans. In addition, supporters would argue that the belief would strengthen the union, making it invulnerable. On the opposing side, consisting mostly of the Whig party, the God-given right to expand all the way westward at the price and rights of thousands of innocent natives was blasphemy. The Whig party was not manifest destinies only critic, abolitionist, fearful of slavery spreading, argued that the constitution did not give the country the right to gain new land and the country’s vital institutions would suffer as America was spread too thin. Look more:  essays on manifest destiny Texas’ sought to join America as a new state, after it gained independence from Mexico and had a revolution. The process of expansion in which newly democratic and free states would seek entry into the United States, rather than the U.S. extending its government over unwanting people was ideal. The Democratic Party was threatened to fall apart if Texas entered the Union, as it would become another slave state and this forced both Presidents Jackson and Van Buren to decline Texas’ plea. During the election of 1844, both Henry Clay of the Whig Party and Van Buren of the Democratic Party were against the annexation of Texas, this displeased the Democrats as they wanted to gain Texas so they dropped Van Buren in favor of James Polk, who was for adding Texas as another slave state. Polk cleverly tied Texas’ annexation into the Oregon dispute, the controversy over Oregon’s border. In 1846 the dispute was settled over the Oregon Treaty where the British relinquished its holding to the lower Colombia basin. This appeased expansionist in the north, who fought for Oregon and expansionist in the south, who focused primarily on Texas. After Polk’s election, he moved to occupy a free portion of Texas that was still claimed by Mexico. This sparked the Mexican-American War in 1846, were there were calls for â€Å"All Mexico†, mostly from Eastern Democrats, however Mexico’s annexation brought up much debate. If Mexico were to become a part of the United States it would mean millions of non-white Mexicans would become U.S. citizens, something Americans were not too keen on. The racist aspect of Manifest Destiny considers inferior Mexicans unqualified to become Americans whereas the mission aspect of Manifest Destiny dictates that Mexicans would become improved under American democracy. The â€Å"All Mexico† movement quickly abated with the Treaty of Guadalupe Hidalgo in 1848 which granted Alta California and Nuevo Mà ©xico to the United States, both of which were sparsely populated with Mexicans. After the Mexican-American War ended in 1848, disagreements over the expansion of slavery made further annexation by conquest too divisive to be official government policy. The belief in Manifest Destiny in the 1840’s greatly influenced both U.S. politics and policy and is to blame or thank for Americas expansion from â€Å"sea to shining sea.†

Pulmonary Embolism as Manifestation of Right Atrial Myxoma

Pulmonary Embolism as Manifestation of Right Atrial Myxoma A  case report and review of literature Abstract We present a case of a 55-year-old man who suffered from shortness of breath and syncope; he was sent to our department for suspecting pulmonary embolism. We proceeded Computed tomography pulmonary angiography (CTPA) and Transthoracic echocardiogram (TTE) , confirmed the diagnosis which was caused by right atrial mass. After the surgery the patient was diagnosed as right atrial myoma (RAM) with pulmonary myoma emboli without no adverse event. The residual emboli were partially improved after one month anticoagulation. We reported this case and review of the relevent literature to help clinicians improve the understanding of diagnosis and treatment of pulmonary embolism caused by RAM. Key words: pulmonary embolism, right atrial myxoma, treatment Pulmonary embolism, most commonly originating from deep venous thrombosis (DVT) of the legs, ranges from asymptomatic, incidentally discovered emboli to massive thromboembolism causing immediate death. PTE is a life-threatening disease with a high morbidity. Annually, as many as 300,000 people in the United States die from acute PTE, which is much more common in China at present than 10 years ago (1). About 50-70% emboli of pulmonary embolism originated from deep venous thrombosis (DVT), most of which in lower extremities. Such patients without DVT should screen occult cancer. Although cancer associated venous thrombosis was widespread described, the emboli from benign tumor are less mentioned (2). Majority of the atrial myxoma complicated pulmonary emboli are tumoral, thrombotic emboli were less reported (3,4). We report a rare case of RAM with a pulmonary localization mimicking pulmonary emboli. Case presentation A 55-year-old man was admitted to emergency room with gradually increased shortness of breath for 2 months, syncope and right chest pain for 6 hours. He had a habit of long time sitting and a history of 20 pack-year smoking, and stopped smoking 10 years prior to admission. Initial assessment revealed cyanosis and right breath sound decreased. No pitting edema in lower extremities. Laboratory tests showed ALT 52IU/liter; 93IU/liter; D-Dimer >10ÃŽ ¼g/ml; NT-proBNP 3544 Ñâ‚ ¬g/ml; Troponin I 0.49 ng/ml. Arterial blood gases revealed severe hypoxemia, oxygenation index was 89mmHg; Electrocardiogram showed Sà ¢Ã¢â‚¬ ¦Ã‚  Qà ¢Ã¢â‚¬ ¦Ã‚ ¢Tà ¢Ã¢â‚¬ ¦Ã‚ ¢. CTPA revealed right main (Figure 1a), both lobar(Figure 1b,1c) and segmental (Figure 1d) pulmonary arteries(PA) multiple filling defects; right atrium irregular mass(Figure 1d). TTE showed enlargement of right chambers and a right atrial 54*47mm mass attached to the top wall, clear margin, irregular and partial rough on surface, l oose in internal structure, moving along with cardiac cycle, mild prolapse through the leaflets of the tricuspid valve and orifice of inferior vena cava, moderate regurgitation of tricuspid valves with mild pulmonary hypertension. Compressed venous ultrasonography showed negative in both lower limbs. The surgical approach was through a medial sternotomy under extracorporeal circulation. The right atrium wall was opened and a gelatinous consistency tumor with necrosis, fragile, measuring 40*50mm, adhering to the inter-atrial septum (Figure 2), a 30*20*70mm tumor embolus in the right main PA, the distal end was near right upper PA. The tumor cells expressed CD34 and calretinin, and were negative for CK and SMA. The histopathological examination confirmed myxoma (Figure 3) in right atrium and right pulmonary artery. The patient was treated warfarin (target INR, 2-3) for 1 month. Repeated CTPA showed left lower PA filling defect with no improvement after 2 months (Figure 4c), right and other left PA filling defect resolved (Figure 4a, 4b). 2 years follow-up he was asymptomatic. Discussion Cardiac tumors are less common, most of which are from metastasis. The incidence rate of primary cardiac tumors (PCTs) in autopsy ranges from 0.02 to 2.8†°. 30-50% of PCTs are myomas, 75% in the left atrium and only 10-20% arising in the right atrium, which may developing from embryonic or primitive gut rests (5,6,7). Histologically, they consist of an acid-mucopolysaccharide rich stroma. Polygonal cells arranged in single or small clusters are scattered among the matrix. The clinical manifestations of RAM may remain asymptomatic or appear with constitutional, obstructive or embolic symptoms according to the size, fragility, mobility, location of the tumor as well as body position and activity (5,8). Nonspecific constitutional signs, which present in 10-45% of patients with myxoma, are fatigue, fever, dyspnea, chronic anemia, weight loss, general arthralgia, and increase of IL-6, ESR, and CRP (8). Therefore the results of laboratory tests may mimic those for rheumatic disorders. These signs are more common for patients with large, multiple, or recurrent tumors, and usually recovered after resection (9). Pulmonary embolism of RAM fragments or thrombi from the surface may also occur, resulting in dyspnea, pleuritic chest pain, hemoptysis, syncope, pulmonary hypertension and right heart failure even sudden death. Acute abdominal pain was mentioned in two cases (10). Embolic event in cardiac myxoma is common, with the incidence ranging from 30% to 40% (5) . In the cases of RAM with pulmonary embolism, a smaller size, villous or irregular surface and multi-foci are most common factors associated with embolization (11). The duration period was ranging from 1 day to 3.5 years. The age of patients ranged from 17 to 76 years (mean age 42.8 years), with a higher incidence in women (20/35, 57%). In these cases RAMs are usually attached by a short pedicle to the inter-atrial septum (22/35), mostly in fossa ovalis, others are in free wall, crista terminalis, Koch triangle and multiple origins. Most of the patients were diagnosed with TTE (Transthoracic echocardiography), CT, transesophageal echocardiography (TEE) and magnetic resonance imaging (MRI), others were with angiography and autopsy. In almost all cases treatment was surgical with removal of the intra-atrial myxomas and the pulmonary emboli, which are usually tumoral. Majority of such patients recovered well after surgery. Four preoperative deaths, two postoperative deaths were reported. Right atrial thrombosis, transient ischemic attack (TIA), ischemic hepatitis and renal failure were the rare complication (Table 1). TTE and TEE are the most commonly used diagnostic methods in the detection and initial description of atrial myxomas (23). TTE is nearly 95% sensitive for the confirmation of cardiac myxomas, and TEE reaches nearly 100% sensitivity (45). TTE facilitated bedside test to safely detect myxomas in fatal pulmonary embolism as in our patient. TEE produces explicit images of small tumors (1 to 3 mm in diameter), especially in fat patients with poor TTE images (46). The TEE also permits a clearer picture of the attachment of the tumor and more precise characterization of the size, shape, surface, inner structure and location of the mass (47). Although TEE is a semi-invasive diagnostic test with a very low rate of significant complications, lethal pulmonary embolism during TEE procedure has been reported (22). Superior to echocardiography, multi-detectors spiral computed tomography (MSCT) and cardiac magnetic resonance imaging (CMR) are more accurate in determining the relationship to normal intra-cardiac structures and tumor infiltration into the pericardium, extension to adjacent vasculature and mediastinal structures, pulmonary arteries emboli and surgical planning (48,49). RAMs manifest as a low-attenuation intra-atrium mass with a smooth, irregular or villous surface on MSCT. Calcifications are seen in about 14% and are more common in right side lesions. Arterial-phase contrast enhancement is usually not apparent, but heterogeneous enhancement is reported on studies performed with a longer time delay (50,51). Varying amounts of myxoid, calcified, hemorrhagic, and necrotic tissue gives them heterogeneous appearances on T1 and T2-weighted images. Delayed enhancement is typical and usually patchy in nature. Steady state free preceesion (SSFP) sequences may slow prolapse through the tricu spid valve in diastole phase and can suggest the attachment point of a stalk lesion. Reconstruction of cine gradient recalled echo (GRE) images enables assessment of lesion mobility and attachment (52). 18F-FDG PET/CT can help the noninvasive preoperative confirmation of malignancy (41). Mean SUVmax was 2.8 ±0.6 in benign cardiac tumors and significantly higher in both malignant primary and secondary cases. (8.0 ±2.1 and 10.8 ±4.9). The SUVmax of myxoma is ranging from 1.6 to 4. Malignancy was determined with a sensitivity of 100% and specificity of 86% with a cut-off SUVmax value of 3.5. A weak correlation between the SUVmax and the size of tumors is found due to the partial volume effect, cardiac motion and respirtatory movement (53). Angiography is an invasive investigation that presents an additional risk of inducing migration of the tumor and only suitable for suspected acute coronary heart disease (37). Surgical removal of the RAM with pulmonary embolism is the first treatment of choice and usually curative (44,45). The crucial aspects of surgery are measures for bi-caval cannulation to prevent intra-operative embolism (27), en-bloc excision of the myxoma with a wide cuff of normal tissue, removal of fragments in pulmonary arteries, and conducted under moderate or deep hypothermia, low circulatory flow or total circulatory arrest based on the extent and sites of the emboli (44). Surgical treatment leads to complete resolution with low rates of recurrence and good long-term survival. The overall recurrence rate is about 1–3% for sporadic atrial myxoma (5,54), which grows an average of 0.24–1.6 cm per year. The risk of recurrence pulmonary embolism after resection has been reported to be 0.4% to 5.0% and interval from excision to recurrence is reported ranging from a few months to 8 years (55). The reasons of RAM recurrence include multifocal origin, incomplete surgical resection, familial disposition or abnormal DNA ploidy pattern. Postoperative annual TTE, V/Q scan for long-term observation should be followed up to detect eventual recurrence of new myxoma and pulmonary embolism. Excision of the recurrent lesions may be the only choice of treatment because of the poor role of chemotherapy and radiation (28). Pulmonary emboli from RAM are usually tumoral, although discriminating myxomas from thrombi in pulmonary arteries is difficult. Daniel T et al (56) presented the first case of paradoxical pulmonary embolism in the presence of a left atrial myxoma withouingt intra-cardiac shunting, potentially secondary to a combination of hemolysis, hemeoxygenase-1 up-regulation, systemic hypercoagulability/hypofibrinolysis, and regional venous stasis. Pulmonary thromboembolism complicated to RAM improved by coumadin therapy in a refused surgery patient (40). In our case the surgery do not remove the right side emboli, while anticoagulation was helpful for residue emboli remission, which confirmed coexistence of myxoma and thrombi. We suggest anticoagulation may be the useful in unresectable myxoma with pulmonary embolism. The duration of anticoagulation in pulmonary thromboembolism is at least three months, but the course in patients with RAM is still unknown. Conclusion According to review of the literature, RAM may not be timely diagnosed, or even totally undiagnosed. Because of the fragile consistency of RAM, pulmonary embolism are the most common comorbidity and mortality disease, usually be fatal. Surgical removal of masses from the atrium and pulmonary arteries is almost uneventful. Although the association between right atrial myxoma and pulmonary embolism has been described, the presence of thrombi was less mentioned. We suggest anticoagulation may be a choice of treatment after operation, especially in incomplete resection cases. Annual TTE and V/Q are suggested for a period of 8 years when the risk of recurrence is reported. Competing interests The authors declare that they have no competing interests.

Sears Case Study Essay -- essays research papers

Sears Case Study Introduction The great advantage of publicly held companies is that they bring together capital and managerial expertise, to the benefit of both groups. An investor need not know anything about making or marketing chairs in order to invest in a chair factory. A gifted producer or seller of chairs need not have capital in order to start a business. When it runs well, both profit, and the capitalist system achieves its goals. Our system of capitalism has been less successful when the company does not run well. As some of America's most visible, powerful, and successful companies began to slide, they demonstrated an all-but fatal weakness in the ability of our system to react in time to prevent disaster. Managers and directors at companies like IBM, General Motors, and Sears took their success--and their customers--for granted. They took their investors for granted, too, until it was almost too late. The problem is that the strength of the system, the separation of ownership and control, is also its weakness. A shareholder's investment in a chair factory gives him certain rights, including the right to elect the directors and the right to inspect the books. These rights may have some meaning when the company is small enough that the investors number in the hundreds. But in large, complex companies, with investors in the millions, they are likely to exercise a third right, the right to sell. While some economists will argue sale of the stock sends a signficant message to management, I agree with Edward Jay Epstein, who said that "just the exchange of one powerless shareholder for another in a corporation, while it may lessen the market price of shares, will not dislodge management--or even threaten it. On th... ...illing the vacancies left by the directors "fired" in the 1991 shrinkage. Ironically, Sears was left with a board with a higher percentage of outside directors. I believe Brennan found that at least some of the extra accountability I was seeking was the result of the actions he took to stop me. Less than six months after the annual meeting, Sears announced a massive restructuring. Coldwell Banker would be sold off in its entirety, Dean Witter would be spun off to shareholders, as would 20 percent of Allstate. The market reacted to the news by sending Sears' stock up 8 percent in a single day. Changes at Sears I firmly believe that Sears' recent renaissance (STOCK PRICES) is a direct result of the increased accountability of management. I believe that Sears serves as a perfect study for the values to be generated by involved and informed shareholders.

Harlem’s darkness and hardships

Baldwin’s â€Å"Sonny’s Blues† is a story of the two brothers living in Harlem. Harlem is the place where the two brothers experienced the darkness of the society. This darkness points out racism and drug abuse as one of the major problems experiencing by many African-American in Harlem. Even though racism was felt by the two brothers and drug abuse hunted Sonny, one of the two brothers, they still managed to adopt and survive through the help of each other. At the beginning of the story, the older brother is on his way to work as a schoolteacher.As he travels down the road, he also reads the newspaper and found out that his brother was caught dealing with heroine. Even before, Sonny was suspected by his older brother of using illegal drugs but the older brother does nothing. Before the drug related incident happens, the older brother who is also the narrator of the story always talks about Sonny as being a good brother. He says â€Å"When Sonny was young, his f ace was bright and open†. Sonny’s brother worries about the involvement of Sonny in illegal drugs.Sonny is being dependent on drugs and uses it as a way to escape his problems. This problem makes his brother think of the things he did wrong to make Sonny involved in drug addiction. As a result of that, the brother misinterprets all the acts Sonny is doing. He does not listen to Sonny even if it has to be about the explanation and reasons of why Sonny engaged to drug related activities. Sonny finds himself neglected by his brother. This makes him think that no one could help him but his own self. Realizing this, he diverts his attention to music.This involvement to music makes him finds the relief he is searching for. With the music playing, Sonny is able to escape the problems he is encountering. The improvement of Sonny is hardly noticed by his brother. At first, his involvement to music disappoints his brother not until his brother realizes the changes music has done to Sonny. His brother accepts the truth and realizes that music has done a good job to Sonny’s development. It all happened in the part of the story where his brother is listening to Sonny as he plays the piano.As Sonny plays the piano, his brother feels that Sonny need his guidance and love. The unconditional love by the brother to Sonny was depicted in the story. Listening to the Jazz music played by Sonny, the attitude of the brother towards life, himself and Sonny changes. The estrangement of the two brothers hurt them both. Sonny’s dedication to music and his determination to stay away from any form of illegal drugs move the older brother to change. The love and passion of both brothers are shown in the story.Their fight against the darkness in Harlem made them realize that to win is to accept the weakness of each one of them and to be able to survive is to help each other. As a final point, to be able to survive in a society where you are not the main character, you must learn to adapt and to help others that are also adapting. The challenges of Black American brothers in the time of racism and its fight against illegal drugs can be solve if trust, acceptance and love is within the family ties.
