The Heart And Its Diseases Essays - RTT, Congenital Heart Disease

The Heart And Its Diseases The Heart and Its Diseases Cardiology has intrigued me since I was a small child. It has been my goal to become a cardiologist ever since the first grade. Cardiology is more than just studying the heart. To define it properly would be to say that cardiology is the study of the heart, its action, and its diseases (Clayman 52). The heart is located in the center of the chest, just behind the sternum, sitting in a hollow cavity between the lungs. The heart is slightly larger than your fist. It is about five inches long, three inches wide, and two inches thick. The heart is commonly represented in the familiar Valentine shape, but it actually resembles a grapefruit. The external features of the heart consist of the pericardium. The function of the pericardium is to support and protect the heart. The inside of the pericardium is lined with a membrane that secrets a lubrication fluid which allows the pericardium to slide smoothly over the surface as the heart pumps. The internal features of the heart are quite a bit more complicated than the external features. The main features internally are the hearts four hollow spaces, which are referred to as the chambers (Clayman 86). The pumping part of the heart consists of two very thin walled upper chambers, which are given the name atria. The two thick-walled lower chambers of the heart are called ventricles. The wall that divides the right side of the heart from the left is called the septum. The muscles in these walls of the chambers provide the pumping action of the heart. These muscles cause the chamber to contract forcefully when the heart beats, which pushes blood through the body. The chambers of the heart can be divided into three layers. The most important of the three is the myocardium, which contains the muscles of the heart. The other two are called the endocardium and the epicardium. The heart has a left and right side, which contains these atriums and ventricles. There are four valves, which aid in the function of keeping blood flowing in the right direction (Katz 75). Two of these are known as the atrio-ventricular valves. These two are named the mitral valve and the tricuspid valve. These valves allow the blood to flow from each atrium into the corresponding ventricle. The mitral valve connects the left atrium to the left ventricle, while the tricuspid connects the right atrium to the right ventricle. The other two valves in the heart allow blood to flow to the body from the ventricles but prevent blood from flowing backward into the ventricles from the body. These valves are known as the semilunar valves. They are named this because they are somewhat shaped like a crescent moon. The aortic semilunar valve allows blood to exit the left ventricle and enter the aorta. The aorta carries blood to the body tissues. The other valve is called the pulmonary similunar valve, which allows blood to exit the right ventricle and enter the pulmonary arte ries. These arteries carry blood to the lungs to absorb oxygen, which is essential to our existence. These valves are designed to move blood in one direction only, unless damaged by injury or disease. The heart can be viewed as a precisely designed two-stage pump. The first stage is the two atria, whose function is to ensure that the ventricles are fully inflated with blood. When this occurs, the ventricles contract to force blood out into the body. Although both sides of the heart contract at the same time, they have very different functions. The right side of the heart receives oxygen free blood from the body and pumps it to the lungs. The left side receives oxygen rich blood from the lungs and pumps it to the rest of the body (Katz 95). Each red blood cell passes through the heart twice on its way to tissues. The venae cavae aids in this process by returning the deoxygenated blood to the heart. The venae cavae is also the largest vein in the body. The superior venae cavae returns blood from the upper part of the body, while the inferior venae cavae returns blood

Argument Essay on Education Essays

Argument Essay on Education Essays Argument Essay on Education Essay Argument Essay on Education Essay Argument Essay Many graduates from post secondary acquire their career with a graduate degree. Students build their credentials and portfolio through educations and programs they receive from post secondary, and seek to target a specific labor field or institutions to work for. With the help of graduate degree that increases students value in labor market, it is easier to pin point in a career pursue. A national strategy that promotes and supports the post-secondary into labor field loud bring success for both students and nations, however, because many nations such as Canada lacks to recognize the national strategy, the nation is unique in its failure to develop success in universities and colleges. A national strategy is a strategy that clarifies what the country expects from the institutions creating its next generation of leaders and skilled workers. The objective of the strategy promotes students to make use of their credentials well in right economy at the right time. For this to happen, a national strategy offers students to achieve flexible transaction to different institutions, by allowing credentials from different institutions as an applicable source. With the ability to make full use of sources of their own and be able to apply it, students wouldnt suffer from being troubled with not being able to get into desired institution. Ability to make use of credential anywhere, it may bring harm instead of benefit to postsecondary education. Because national strategy allows one to be able to make their credentials worth in NY level of institution, but without it, it will only lead talents or passionate students to waste. For example , a college students had its admission denied into JIBE law school because of his college credential; based on his stellar LAST score , he went off to Oxford instead. Because there was a barrier that alienated students from being able to determine their ability due to lack of opportunity that is offered , instead it could lead alternate route since Canada does not offer any alternate route of applying to an institution. In conclusion, national strategy brings benefit to postsecondary environment, it will lead a nation to right direction in building many successes in future as each generation will be able to seed its growth into the labor market. For nation to maximize its efficiency in productivity resources in its nation , not only is it recommended but I believe that its a pre requisite course of action to take in order to build best of world for theory-based , hands on , and Job friendly university education passionate students.

Physical Security Clients Assessment (Criminal Justice) Essay

Physical Security Clients Assessment (Criminal Justice) - Essay Example insecurity present most intense effects of floods, earthquakes and volcanoes among others just as those that are man-made including civil disturbances, industrial accidents and sabotage. Security forces and those installing security devices therefore need to be armed with adequate skills through vulnerability tests, training and supervision. With the increase in buildings, security and safety become paramount. There are varied risks associated with buildings including disorder, emergencies and crime. The crimes that could be committed in contravention to building security include theft and burglary, property damage including sabotage and graffiti, personal offenses such as elevator assaults, public order offences such as angry interchanges with receptionists and unauthorized access to utilities that could lead to commercial espionage. Disorders encompass behavioral issues such as drug dealing and hostage taking in buildings (Challinger, 2008). Fennelly acknowledges the importance of â€Å"territorial defense strategies† as a way to prevent property related crimes including household larceny, auto theft and break-ins (2004, p.5). The related strategy areas in this case include construction standards, building interior security, building perimeter security and building grounds security. Grounds security would protect against unauthorized entry into sites and inhibits destructive behavior by visitors. Construction standards ensure that the materials and techniques used in construction minimize safety hazards and crimes. Interior security provides a third line of defense by use of physical barriers and surveillance to prevent unauthorized access and ensure security of occupants. Reese and Tong (2010) point out the physical security of federal buildings and include assets of physical security such as closed-circuit television cameras, safety guards and barrier material. Since the September 2001 terrorist attacks on the World Trade Center and Pentagon, there have been

Business Ethics - Essay Example Thus, it is expected that the modern business will work for achieving growth and success for both the individual company and their communities (Business Ethics). The social and environmental thinking of business not only encompass a legal duty but also the long-term success of the business. Argument Businesses are operated within the society using the resources from and depending on the society for the proper functioning of the business operations. Therefore attending to the welfare of the society is an obligation or a responsibility on the part of the business organizations. Thus, the social responsibility of business forbids businesspersons in adopting unfair policies that may maximize the profit of the business but harm the interest of the society. Welfare activities on the part of the business organization gain benevolence and reputation. Business carrying out their duties properly can avoid government regulations. The employees are more satisfied if a good working environment is provided with some additional facilities. This in turn increases their productivity and hence facilitates the business. Last but not the least, providing quality products to the consumers at competitive prices is also necessary in the days of increasing consumer awareness about their rights. The integral development of human being is related with the obligations that may arise because of the relationship of man with the environment. Business or the material environment has been taking its toll on the environment and questioning the sustainability of future generations with the increasing pollution, new illnesses and its destructive capacity. If these are not immediately controlled then it may create immense problem for the entire human class. The problems of the ecological and environmental crisis cannot be looked upon distinctly from the notions of development. The obligations of the business towards the environment include consideration of the environment in the decision-making p rocesses and thereafter supervise the activities. There are obligations including monitoring of proper discharge of water. Proper insurance should be done against environmental damage. The environmental taxes and the charges should be paid properly. The land that is being used for the construction purpose should follow proper planning norms and the environmental legislation unit of the country should approve the product. According to the definition of sustainable development, a development is said to be sustainable if the present generation can provide the future generations with at least the same benefits that it inherited from the past generation if not more. However, if the environmental degradation continues then the future generation will not be left also with their basic requirements for a proper living. Since the natural resources are scarce, the use of those resources by the business organizations in their production should be limited and handed in a proper manner to reduce misutilization. Negligence or refusal on the part of a few people in handling the stewardship of the environment in a responsible manner may invite the larger population to experience ‘increased hardship’. The creation of the God is for all human beings and generations and hence needed to be shared equally by the humanity as a whole. The supplies of certain natural resources

Teaching Citizenship Essay Example | Topics and Well Written Essays - 2000 words

Teaching Citizenship - Essay Example Citizenship, exclusively, is both a discrete subject and also a culture - which is a way of living with its own distinct set of values, attitudes and nature which supports continuous lifelong learning. Since citizenship education is so completely new to the curriculum in most schools, the timetable contexts in which it takes place are likely to vary quite considerably. 'Many schools are recognizing the wider benefits of citizenship and offer 'special themed days' with a collapsed timetable and specialist speakers. In some schools, citizenship may be part of, and an extension to, existing programme of Pastoral, Social and Health Education (PSHE). In others there may be timetable slots quite explicitly labelled 'Citizenship'. In yet others, the requirements of the citizenship curriculum may be addressed within a framework of 'Humanities' teaching. Still other schools may decide to address citizenship in a totally 'embedded' cross-curricular way, identifying specific elements of the citizenship curriculum to be included in individual subject departments' schemes of work. Some schools are taking the opportunity to reflect on their organisation and are embracing a citizenship ethos in which citizenship concepts and knowledge are developed through active participation and greater learner responsibility. These schools have effective schools councils, student consultation and representation, shadowing, specialist student training, peer work, whole school special focus days, local and national student elections, involvement with other schools and links with the wider community including their local councilors and MP. Trainees on the course are encouraged to see themselves, first and foremost, as citizenship teachers capable of straddling most, if not all, of the fields of knowledge and pedagogical approaches to which reference has been made. Realistically, and in order to build a viable personal teaching timetable while on school experience, there may be a need to undertake some work in a 'traditional' subject allied to your degree specialism. Some students, (for example, those with degrees in psychology or sociology), may be able to contribute to post-16 teaching in these subjects. Trainees will need to be enterprising; prepared to take considerable responsibility for their own professional development; daring enough to want to shape the future of citizenship education; and dedicated to (and preferably with some successful experience of) 'making a difference' to the lives of young people'. (Graduate School of Education, Copyright 2007 - University of Bristol.) Teaching Citizenship through history: 'Citizenship and History can be seen as natural partners - this was confirmed by Sir Bernard Crick, the founding father of the modern Citizenship education movement in England: " My personal view, that I have had to be a little bit discreet about at times, is that of all the other subjects History may have (should have) overall the greatest role to playSeeley

Factors Responsible for Employee Retention

Factors Responsible for Employee Retention Strategic Human Capital Management The paper is generated by referring to Christeen George’s article paper, with title of Retaining professional workers: what makes them stay?. The main issue normally practice by Human Resource is to let the turnover occur then only to find out the reason of the intention to quit through exit-interview. Knowing the reason only after people quit is seem defenseless because the collected information on why people quit fail to restore back the job gap. Hence, the purpose of this paper is to identify the factors that capable to retain the professional staffs in one organization, then the factors are tested for the retention of the professional employees. The variables used in this paper are divided into two dimensions, first dimension is organizational which consist of four factors, management, conducive environment, social support and development, second dimension is job which consist of four factors, autonomy, compensation, crafted/sculpted workload, work-life balance. Hence, the paper is driven by research questions, which are to explore whether the eight factors identified in this paper is usable to measure the individual intention to stay in the organization, are the factors identified distributed into organizational group and job group is blended positively, and whether the organizational level and job level could predict the individual’s intention to stay in the organization. The study area is conducted in UK site, the sample of the study is focusing the employees of multinational marketing company which come from variety job function such as Accountant, IT professionals, Consultants, Marketing and Sales professionals, and HR professional. The total respondents are 138, which covered 76 male, 62 female. The age range from 20 to 61 years. The measurement instrument, the questionnaires were electronically sent to the respondents. The independent variables (IV) content of sex, age, organizational level scores and job level scores showed significant result, and that showed the IVs used are able to predict the intention of the employee to stay and to quit. The most durable IV to predict the intention of the employee to stay and to quit is organizational level scores which consist the characteristics of leadership and support from management, work environment is fun, flexibility, adequate resources, feel belong to the team, friendly and caring workmates, opportunity to enhance/acquire skills, promotion prospects. Meanwhile, the eight factors that distributed into organizational level and job level showed significant positive correlations respectively, and that showcase the eight factors were distributed in the correct group. Many researchers and academias give substantial focus on the impact of employee turnover, the turnover impact towards organization cause high cost. This is supported by Ghosh, Satyawadi, Joshi and Shadman (2013) literature finding stated an internal analysis has shared to replace turnover employee is more expensive than compensate employee, which is more than 35 per cent. Knowing the big loss could occur to any organization due to turnover, it is wise to prevent better than cure, the idiom may sound clichà ©, but it is a crucial issue to tackle in order to assist the organization to save the resources. Apart of loss in revenue, the organization is facing the risk of loss of experience employees, bad reputation to other organization, productivity is affected, loss of intellectual capital which knowledge is one of the valuable intangible asset to the organization (Sandhu, Jain, Ahmad, 2011) and this lead to other organization gain more advantage by obtaining the asset (Ghosh et al., 2013). Turnover issue is inevitable, however the issue could be alleviated with the help of research. Hence, the paper is creating awareness about it is more advantage to identify factors that make the professional employees stay rather to identify factors on why they are quit. The paper could help the organization to understand the proven factors (management, conducive environment, social support and development under organization level is the most durable predictor) resulted from this study to strategize on how to retain the professional employees in the organization. However, there are arose enquiries on the part of independent variables and dependent variable stated in the paper. The term of independent variable is viewed as an item that influence the outcome, meanwhile dependent variable is viewed as an outcome which may result different outcome for different independent variable are used to test (Leroy, 2011). Based to the term defined, the organizational subscale which consist of four factors, management, conducive environment, social support and development, and job subscale which consist of four factors, autonomy, compensation, crafted/sculpted workload, work-life balance are responsible to influence the result of retention. Thus, the reader expected the identified variables in the paper, organization subscale and job subscale are independent variable, and intention to quit is dependent variable, however, it is stated in opposite statement. The enquiries arose are not meant to downgrade the content of the paper, in fact, the reader made cor respondent via e-mail on 11 March 2015 as in appendix to the author, respond is yet pending. The purpose of the e-mail is sent with respect and courtesy, and to clarify the doubtful and ambiguity as well. In Malaysia context, one study presented at the 2nd International Conference On Management, Economics And Finance in Sabah by Fadzilah, Queiri, Sabarudin and Iskandar (2013) claimed that Generation Y is more likely to quit their job due to several reasons such as lack of fun work. This issue is critical and need to be taken seriously by the organization because the contribution of Generation Y towards in any economy is significant, and they are growing fast and bigger employees to replace the Baby Boomers who are in line of retirement. Generation Y showcase different characteristics when come to work which influence by leadership, developments and technologies (Cheong, Hasliza, Yusuf Desa, 2011). Despite the respondents’ age range between 21-61 years old in the paper, which mean Generation Y and Baby Boomers are part of the respondents, the paper is capable to provide a foundation framework on how the Malaysia organizations design a strategy to retain the Generation Y. This i s rational because the study conducted by the author tested the similar factors that influence Generation Y when come to work, leadership and development. Malaysia is gearing up to beef up the human capital development by producing first class mentality, knowledge-based economy and talent-based. For instance, Talent Corporation Malaysia (TalentCorp) is responsible to facilitate the talent management in Malaysia. The biggest hurdle encountered by TalentCorp is brain drain. The professional employees choose to leave Malaysia and work abroad. TalentCorp has come with a strategy to attract and retain the professional employees which they offer various packages, such as tax exception and work life balance. Work life balance is one factor tested in the author’s study and that it is proven that the significant of the study does promote to other agency that associate to human resource such as TalentCorp to infuse the factor into part of their retention strategy. Knowing the present of TalentCorp is vital to constantly conduct research in order to ensure the objectives are achieved, thus, this paper could help TalentCorp to come out with a robust blueprint regards strategy on retaining professional employees, of which TalentCorp may considers the tested factors in the paper such as social support. Finally, the research is emphasizing the needs to increase the number of respondents, and needed to expand larger coverage of organizations and professional employees. The wider scope as it may goes, the possibility differ outcome it may be. The factors identified and tested in this study which distributed into organizational level and job level are proven related to the individual intention to stay and to quit. Thus, the finding show significant positive for human resource and organization to design a robust strategy to retain employees. The negative impacts due to turnover or quit the job that discussed in this review could be alleviated by the help of to understand the factors influence the intention to stay and to quit. However, one of the factor in the framework model, which is compensation, may cause the small, medium, enterprises organizations to consider to use it as one of the retention strategy as they are unable to offer competitive compensation packages compare to larger organizations who use compensation as one of their retention strategies, this is supported by Ghosh et al. (2013) stated large organizations could afford to provide better compensation package such as appreciation and recognition award. In the other hand, the future research suggested in the paper is to examine the relation between employee engagement, employee retention and organizational performance. The significant of the future research would create a wider scope for the organization to understand and harvest the benefit of retention strategies. REFERENCES Cheong, T.

Did The Expansion Of The Aztec Empire Lead To Their Downfall? :: essays research papers

Did the Expansion of the Aztec Empire Lead to Their Downfall?   Ã‚  Ã‚  Ã‚  Ã‚  The Aztec Indians originated from a place called Aztlan, somewhere in north or northwest Mexico. At that time the Aztecs were a small, nomadic tribe living in the border territory on the margins of civilized Mesoamerica. (see map I) In the 13th century they settled in the valley of central Mexico. The Aztecs finally found refuge on a small island in Lake Texcoco, where about 1345, they founded the town of Tenochtitlan. The island was found through a prophecy which said they would settle where they found an eagle perched on a cactus. (see diagram I)   Ã‚  Ã‚  Ã‚  Ã‚  During the next century the Aztecs grew to be greatest power in Mexico. As they grew in political status they became sophisticated and civilized, learning from established peoples who had been town dwellers for more than 1,000 years. (Ekholm, Gordon F.)   Ã‚  Ã‚  Ã‚  Ã‚  The Aztec empire consisted of numerous, loosely connected urban communities. Land ownership was communal. Each local group was composed of a few families that jointly owned a piece of land. Part of the yield of cultivated land was given to the state as a kind of tax.   Ã‚  Ã‚  Ã‚  Ã‚  Technology depended more on human skills than on mechanical devices. Iron and steel were unknown, although copper and bronze were used for tools and Mexican jewelers made ornaments from gold, silver, and their alloys. Wheat, barley, cattle, horses, sheep, and goats were unknown until introduced from Europe and the Mexicans were efficient farmers who made full use of irrigation, terracing, and fertilization of the fields.   Ã‚  Ã‚  Ã‚  Ã‚  Aztec Mexico was rich and civilized. The state controlled every aspect of life. Schooling and training in the martial arts were compulsory for all boys, while the girls were trained in gathering, cooking, and the sewing arts. A centralized bureaucracy looked after the collection and storage of taxes, matters of legislation and punishment. (Peterson, Frederick)   Ã‚  Ã‚  Ã‚  Ã‚  Life for the Aztec's was good. Because of the complexity of their government all were happy. Then in 1519 Spanish conquistador, Hernan Cortes, met the Aztec leader Montezuma in Tenochtitlan. Montezuma believed that the Spaniards had come in peace, but he is proven wrong in 1521 when the Spanish, lead by Cortes, violently conquered the Aztec capital of Tenochtitlan.   Ã‚  Ã‚  Ã‚  Ã‚  The purpose of this report is to answer the question â€Å"Did the Expansion of the Aztec Empire Lead to Their Downfall ?† I feel that it most likely did. This is because when the Aztec's were conquered they were the most powerful civilization in the New World. The Spaniards saw them as â€Å"the ones to beat† to gain supreme power in the Americas.
