Marbury V. Madison Trial Essays - , Term Papers

Marbury V. Madison Trial Marbury v. Madison The issue before the Supreme Court was the question of the court's own constitutional authority, and to decide whether or not to issue the writ and if this would make the court seem weak. The facts of the case that were presented in the court was that this particular case was, in fact, being thrown before the Supreme court, and there was an argument as to whether or no the court real had the jurisdiction to decide this case at all. The result of this case was that the Supreme Court decided to entitle Marbury his court order. It was the first time the Court openly declared an act of Congress unconstitutional. The Court ruled that Congress exceeded its power in the Judiciary Act of 1789 and it established its power to review acts of Congress and declare invalid those it found in conflict with the Constitution. I actually think that the framers of the constitution would have consented to the idea of the Court to have this power of Judicial Review, because it works out quite well for the system of checks and balances because without it Congress would almost have too much power and I am sure the framers wouldn't have accepted that. If the decision had not have validated the idea that the Supreme court had the power of Judicial Review, then Americans would have been a little concerned about the competency of the Court and would have thought that it was acting outside it's jurisdiction. Justice Marshall stated that the power to decide this case did not come from the constitution, but from an act of Congress. The Supreme Court further more had original powers that extended beyond the constitution, so, in this case, it had the right to pass judgment. The point of this was in case the Court had to decide, without Congress, if certain cases had to be decided in Court and not in Congress to allow the Supreme Court to go above Congress's head to make an Important decision, and see for itself if the decision of Congress was deemed unconstitutional and if it should be decided in court.

History of Punk essays

History of Punk essays The British rock band manager, Malcolm MacLaren, once remarked that rock music remained the only form of culture that youth - those most receptive to radical ideas, who hold the most potential for social action - cared about. For the young, everything flowed through rock'n'roll: fashion, slang, sexual attitudes, drug habits, and poses. Once he realized the financial potential behind these sociological traits, the cunning MacLaren kept an eye on the rock music underground as a bell whether indicator for the British youth. It was here that MacLaren recognized the highly visible, wildly energetic and anti - social punk was the heir apparent for the youth of the UK. In order to capitalize on this new sound and evolving trend, he began promoting The Sex Pistols. As a savvy businessman, MacLaren knew that in order to succeed he and The Sex Pistols had to reach the largest number of pop culture participants in the most cost-effective manner available. This required a shift from the undergro und scene into the mainstream mass media. While their ploy was successful, success had its price. The deluge of manipulation and the waves of newly found fame forced on The Sex Pistols caused the original punk to become lost. In spite of placing punks on a worldwide stage, success was the end of the quintessential punk and the beginning of punk as a constructed image. An analysis of what punk was, in sociological terms, is rather more interesting than trying to determine what punk meant. This is because, as A.A. Gill of the London Times points out, punk was simply part of the "next" generations "fumbled attempts to get drunk, listen to the band, get laid and get the last bus home..." (Gill 3). Gill implies that punks were merely teenagers doing what came naturally: "We did it because we had to, we were genetically programmed to be adolescent and, anyway, there wasn't anything else to do on Friday night." (Gill 3). He goes on to say that "the kids were al...

ECO..Profits and morality - Assignment Example This is because there will no longer be a motivation to keep doing paying or else the electric supply will be cut off. However, in this case of freedom to decision-making involving consumption has led to a negative outcome reducing the wellbeing of the capitalistic electric company that is there for profit. Another example mentioned involves Ford Pinto model of car and is a quite well-documented incident regarding the defective rear engines of the car that could catch fire following collisions (Sidewinder77, 2007b). If people were given the freedom to decide about the production and buying variables of the car, most individuals would not be willing to pay a higher price for a safer car. This decision would ultimately increase the risk of being susceptible to death by a faulty car because people, if given the freedom to decide, would not always choose rationally thereby reducing overall wellbeing of the

Computer Security Essay Example | Topics and Well Written Essays - 2250 words

Computer Security - Essay Example One study was done by a group of academicians. The second study was done by computer security professionals. One is a seminal work carried out by Farzeneh Asghapour, Debin Lin and Jean Camp (2007) in assessing the indirect and implicit use of mental models applied to computer security. Asghapour et. al., (2007) did three experiments which revealed corresponding results. First, the experiments showed that for a set of security risks, the self-identified security experts and non-experts exhibit specific mental models. Second, a brand of expertise increases the distance between the mental models of non-experts and experts. Finally, the utilization of models through metaphors did not correspond to metaphors that are similar the mental models of simple users. The second study on computer security done by Stuart Schechter and Daniel Smith tackled the kind of security required to protect a packaged system which is present in large organizations from thieves who would plot a vulnerability to attack multiple installations. Both studies are similar since they relay the importance of computer security in organizations. The main theme of Asghapour and her co-researchers were to emphasize the importance of effective security risk communication. The researchers argue that this requires both communicating risk information and motivating the appropriate risk behaviors. The crucial argument is that the purpose of risk communication is not transmitting truth to the users, but training them to take an appropriate move to respond against a certain threat to their system. Similarly, Schechter and David present an economic threat modeling as a measure for understanding adversaries who are attracted for financial gain. They did a mathematical model on thieves outside the target organization who would enter through a simple vulnerability in one of the target company's packaged systems. This model can determine what these thieves are willing to pay for system vulnerabilities and how secure the system should be to withstand any form of theft. The main methodology of Asghapour and her co-researchers were to identify implicit mental models for computer security which makes these explicit and run a test for mental models for fit for risk communication. They also aim to utilize the mental models in a rational manner to address risk communication to non-expert computer users. The researchers pointed out that a mental model is an internal concept of a given process. This concept is case specific and may depend on life experience, description of the risk, type of risk, and information processing strategies. In contrast, the methodology of Stuart Schechter and David Smith in their computer security study was to project economic threat models. The economic threat models they designed were meant to answer these questions: a.) who profits from a computer security attack on a given company; and b.) what is the choice of attack The threat models enable them to pinpoint the adversary and the respective motivation of those. CONCEPTUAL FRAMEWORK Ashgapour and her co-researchers (2007) determined the scope of mental models which are used in the computer security profession. They chose five conceptual models implicit in language and explicit in metaphors: physical safety, medical infections, criminal behavior, warfare and economic failure. Physical safety refers to 'keys', 'safe

To what extent were the diggers who staged the Eureka rebellion of Essay

To what extent were the diggers who staged the Eureka rebellion of December 1854 motivated by democratic ideals - Essay Example Although, the miners lost the battle, they succeeded in gaining greater equality for the miners including the abolition of the License and Gold Commission, as well as the vote for all males. The Eureka stockade can be regarded as the birthplace of Australia’s political system as marked the inception of the right to vote, political equality, and freedom of speech.1 The Eureka revolution represented an earnest attempt at democratic government. The paper maintains that the miners who staged the Eureka rebellion were mainly motivated by democratic ideals, by values and principles against injustice and oppression. Background The gold can be regarded to have been a social transformer, a democratic mineral given that whoever who found had cash in their hands. In order to maintain control on the colony’s critical pastoral industry and preserve its conventional values, Governor La Trobe instituted an emergency system where commissioners enjoyed both judicial and executive powers . This set the stage for the confrontation as the military and the police transformed into an arbitrary force, whose decisions almost unchallenged. A heavy tax as imposed on all individuals who went to dig in an effort to deter men from leaving their regular employment, especially within the pastoral industry. Furthermore, the diggers bought the license at a high price, more than what the squatters paid to graze sheep. Unsurprisingly, the license tax was opposed right from its inception and the majority of the colony’s men condemned the tax and the manner in which the police enforce the tax.2 The failure by the conservative legislative council to substitute the detestable tax with an equitable and less confrontational export duty on gold set the stage for future rebellion. The new governor, Hotham ordered twice-weekly searches to weed out unlicensed miners, which further disillusioned the miners. The move heightened hostility to the overworked and undermanned police force. At the same time, larger complaints were emerging, which rendered licenses to be symbolic. The burning of the licenses derived from the fact that they represented the most evidence of government's injustice.3 The seeds of discord, sown into the soil, can be highlighted as a series of miscarriages of justice, latent within the system. The incidences police mistreatment was subsidiary to the deeply entrenched distrust fuelled by serious miscarriage of justice over the murder of James Scobie by Bentley, who was an ex-convict owner of the Eureka Hotel and exonerated of the murder charge.4 The burning of the hotel in protest to the Bentley verdict marked a turning for both sides. The Eureka episode created disaffection between the two camps, which had threatening undertones. What started as a disconnected series of events triggered by the same flawed system of control gained momentum when the populace reacted to the enquiry into the hotel’s destruction while seizing the opportunity to highlight the long-standing litany of grievances against the government.5 Hotham declined to accept the recommendations, which demanded that the licenses be abolished, and the police return to standard work, but used delaying tactic of a royal commission. The Ballarat miners were by then organized, united, and determined to success. The governor and other officials, on the other hand, sought to conquer the defeat the rebel movements even if it meant the use of military force. The retrial and subsequent conviction

Project Managers Are They Born Or Made Management Essay

Project Managers Are They Born Or Made Management Essay Can a person be born to undertake a specific role in life or are they moulded by both training and their experiences in life. This paper examines whether Project Managers have the innate skills to be a success or if they like many other professionals require training to become proficient in their chosen career. This paper will also examine whether there are particular personality traits that are required in order to be a successful Project Manager. With this information, organisations would then be in a better position to ascertain whether particular individuals are either suited or not to the role of a Project Manager and thereby ensuring that their Project Managers can bring projects to a successful conclusion. Introduction Dittman et al.,2004 use the Apollo 13 incident to illustrate the skills of a Project Manager. Gene Krantz, was the flight director of the Apollo 13 mission to the moon. With systems failing, a lack of power and a dwindling supply of oxygen he led his team to discover solutions against almost impossible odds. Krantz exhibited the characteristics and personality traits of a superstar Project Manager by leading his team to achieve a common goal of ensuring the safe return of the aircraft and the lives of the astronauts and in this instance the team could easily have resigned themselves to their fate or made an error in judgement (Dittman et al.,2004). However the team and its project leader relied on both their training and their instincts to ensure the safe return of the aircraft. It can be seen from this instance that the team leader instilled the thought into all of his team members that failure was not an option. This is an extreme example of the skills required of a Project Manager , but it asks the question were Gene Krantzs actions the product of training and experience or were they innate in his personality. With the rapid advances currently being made in information technology there has now become an increased need for Project Managers within the IT industry. The scale and number of projects has increased thereby increasing the risk associated with these projects. With this in mind the choosing of project managers with the required skills to ensure the successful completion of projects has become critical and organisations have recognized that the choosing of the right individual to lead a project can have a significant bearing on the success of the organisation. As can be seen above in the Apollo 13 example the role of the project leader was crucial to the success of the project. This paper will look at the necessary skills required to be an effective manager and whether these skills are inherent or whether they can be taught (Dittman et al.,2004). 1.0 Leadership Styles Studies have shown that there are primarily six main schools of leadership theory (Dulewicz Higgs, 2003;Handy, 1982; Partington, 2003) and these are as follows: 1. The Trait school 2. The Behavioural or Style school 3. The Contingency school 4. The Visionary or Charismatic school 5. The Emotional Intelligence School 6. The Competency school. 1.1 The Trait School This approach was popular up to the 1940s with the main idea being that effective leaders share common traits. This school of thought assumes that leaders are born, not made. The supporters of this school in attempting to identify the traits of effective leaders have focused on the following three main areas: à ¢Ã¢â€š ¬Ã‚ ¢ Abilities: hard management skills such as Time Management, Forecasting and Procurement à ¢Ã¢â€š ¬Ã‚ ¢ Personality: such as self-confidence and emotional variables à ¢Ã¢â€š ¬Ã‚ ¢ Physical appearance: Project Managers appearance and physical size Through his work at Henley Management College, Turner (1999) identified seven traits of effective project managers: à ¢Ã¢â€š ¬Ã‚ ¢ Problem-solving ability à ¢Ã¢â€š ¬Ã‚ ¢ Results orientation à ¢Ã¢â€š ¬Ã‚ ¢ Energy and initiative à ¢Ã¢â€š ¬Ã‚ ¢ Self-confidence à ¢Ã¢â€š ¬Ã‚ ¢ Perspective à ¢Ã¢â€š ¬Ã‚ ¢ Communication à ¢Ã¢â€š ¬Ã‚ ¢ Negotiating ability. Turners identification of the above traits concentrate on the softer skills of Project Management with only the trait of Problem Solving being one that could possibly be taught and the others being skills of a nature more specific to an individual. 1.2 The Behavioural or Style School The behavioural or style school became popular from the 1940s to the 1960s. This school assumed that effective leaders would adopt certain styles or behaviours. This schools theory assumed, that effective leaders can be made and that the parameters include the following: 1. Concern for people or relationships 2. Concern for production 3. Use of authority 4. Involvement of the team in decision-making (formulating decisions) 5. Involvement of the team in decision-taking (choosing options) 6. Flexibility versus the application of rules. Parameter Blake and 1.3 The Contingency School The contingency school came into being during the 1960s and 1970s (Fiedler, 1967; House, 1971; Krech, et al., 1962; Robbins, 1997). Rather than seeking all encompassing theories of leadership that would apply in all situations, contingency theories suggested that what made an effective leader would depend on the situation that the leaders found themselves in. The supporters of this school had a tendency to follow similar patterns: 1. An assessment of the characteristics of the leader 2. An evaluation of the situation in terms of certain key contingency variables 3. The seeking of a match between the leader and the situation. One contingency theory that has proven popular is path-goal theory (House, 1971). The idea is the leader must help the team find the path to their goals and help them in that process. This theory identifies four distinct leadership behaviours: à ¢Ã¢â€š ¬Ã‚ ¢ Directive leaders à ¢Ã¢â€š ¬Ã‚ ¢ Supportive leaders à ¢Ã¢â€š ¬Ã‚ ¢ Participative leaders à ¢Ã¢â€š ¬Ã‚ ¢ Achievement-oriented leaders. These must then be matched to environmental and subordinate contingency factors: à ¢Ã¢â€š ¬Ã‚ ¢ Environmental factors: Task structure Formal authority system Work group. à ¢Ã¢â€š ¬Ã‚ ¢ Subordinate factors: Locus of control Experience Perceived ability. 1.4 The Visionary or Charismatic School During the 1980s and 1990s, the visionary or charismatic school arose from the study of successful business leaders who were leading their organizations through change. Bass (1990) identified two types of leadership, transactional and transformational: Transactional leadership: This form of leadership rewards followers for meeting performance targets and managing by exception by taking action when tasks have not been undertaken in accordance with what was predicted 1.4.2 Transformational leadership: A Project Manager who displays this form of leadership would be charismatic, visionary and would engender pride, respect and trust. They would also provide motivation by creating high expectations, providing intellectual stimulation and challenging their team members with fresh ideas and approaches. They would also give consideration to individuals by showing them respect and paying personal attention to them. From a project management perspective, Keegan and den Hartog (2004) believed that a project managers leadership style needed to be more transformational than transactional, but did not find any evidence to confirm this. What they were able to conclude was that although there is a significant correlation between the managers leadership style and employees commitment and motivation, there does not exist a similar correlation for project managers. 1.4 The Emotional Intelligence School The emotional intelligence school has flourished since the late 1990s, and espouses the view that the leaders emotional intelligence has a greater impact on his or her success and the performance of his or her team than does the leaders intellectual capability (Goleman, Boyatzis, McKee, 2002). They identified six leadership styles: à ¢Ã¢â€š ¬Ã‚ ¢ Visionary à ¢Ã¢â€š ¬Ã‚ ¢ Democratic à ¢Ã¢â€š ¬Ã‚ ¢ Coaching à ¢Ã¢â€š ¬Ã‚ ¢ Pacesetting à ¢Ã¢â€š ¬Ã‚ ¢ Affiliative à ¢Ã¢â€š ¬Ã‚ ¢ Commanding. Goleman, Boyatzis, and McKee (2002) say that the first four of these styles will engender a sense of teamwork, and usually lead to better performance in appropriate circumstances. They also stated that the last two styles can encourage dissonance, so these last two styles need to be used with care. Goleman, Boyatzis, and McKee, as well as other authors, have shown a clear correlation between the emotional intelligence and leadership style of managers and the performance of their organizations. 1.5 The Competency School The competency school of the 1990s has placed an emphasis on the competencies of effective leaders and seeks to identify them. This according to Turner et al. 2005 when taken at face value may appear to be a return to the trait approach. However, they also state that competencies can be learned, so leaders can be made, not just born. Further, different combinations of competencies can lead to different styles of leadership which can be appropriate in different circumstances thereby producing transactional leaders in situations of low complexity and transformational leaders in situations of high complexity (Turner et al., 2005). 2.0 Skills of a Project Manager A good project manager should have the knowledge and skills necessary to perform their job. A project manager can be defined as the person responsible for working with the project sponsor, the project team, and the other people involved in a project to meet project goals (Schwalbe, 2004). To become an IT project manager requires knowledge in the core skills such as time management, risk management, scope management, cost budgeting, and knowledge of IT systems (Dittman et al., 2004). They also stated that a project manager must have skills in addition to the basics of project management to succeed and that the skills required are the soft skills that have to do with getting things that you want done and adjudicating issues between people, managers, egos and agendas. Its basically how to get a job done without annoying people (Melymuka, 2000). These soft skills can include basic leadership and team building abilities that are needed for the team to complete the designated project and t he basic business skills that are necessary for a project manager to be successful in the IT world (Dittman et al., 2004). They also concluded that these could include the ability to communicate into measurable results, utilize financial skills to keep the project cost effective, and identify and predict trends in the project. The ability to communicate effectively is a pre-requisite in project management and it is essential for project managers to have the capacity to listen and understand the people on their project team as well as the customers of their project and by doing so, expectations and feedback can be easily passed on to the team and it will be easier to solve problems and complete tasks within the project (Dittman et al., 2004).. Dennis Johnson, an Assistant vice President at USAA stated that A project manager needs the ability to question without alienating to listen and watch peoples body language and really see whats happening (Melymuka, 2000) and this skill will enable a project manager to step away from a project and view issues from a different perspective. This subsequently enables a project manager to better communicate his ideas and plans with the team and also with his superiors within the organization. Relationship management is a skill that is important to have While managing projects a project manager should be capable of working with all levels within the organization and relationship management is an important skill to either inherently have or to learn. Relationship management can also include identifying the unique characteristics and abilities of each individual on the team and determine the most effective way to utilize them throughout the project (Dittman et al., 2004). A project manager will also need to know how to mobilize and coach the people on their team and establish trust within the project team. The project manager and the team must develop a level of trust and comfort with each other in single-minded pursuit of project goals (Kharbanda, 2003). This is based on the premise that project managers should be able to build and sustain relationships within their project team and throughout all levels of their organization. There are many skills a project manager may have that are argued to be ingrained in the human spirit, the largest of these being the ability to influence others (Dittman et al., 2004). Linda Pittinger, CEO of People3, states Its hard to find people who can influence others and create win-win situations (Melymuka, 2000). The project manager needs to have the ability to sell the value of the project to other people within the organization and must be able to persuade and influence team members to get their job done well and on time must also have the confidence, credibility, and commitment to overcome the obstacles when faced with the task of running an IT project (Dittman et al., 2004). Without the ability to influence people particularly those who may not be in full support of the project, a project manager will be more likely to fail. The ability to make decisions can be either learned or innate and it has been said that the best decision makers are the most experienced decision makers (Dittman et al., 2004).. As a manager and leader, every step you take required decision making skills. What makes it more challenging is the pressure to make the right decision is often very high (Canterucci, 2003). When faced with having to make the correct decision a Project Manager may often have to base this decision on past experience or pure instinct. Should a project manager be new to the field of project management they will not have accrued sufficient experience to make the correct decision but they will have the ability to judge based on their instinct if those instincts are of a project manager with those innate skills. As can be seen above many of the skills required to be an effective project manager are the softer skills of management and that to a large extent these skills can not generally be taught as they rely on the individuals personality. These softer skills however can be honed through time and experience so to some extent there is a degree of learning. 3.0 Personalities of a Project Manager In order to be an effective project manager a persons character and personality traits will play a key role. Dittman et al. 2004 asked the question Within an IT project management program, can people be really prepared for the trials and tribulations of dealing with people while managing a project? The use of personality tests, such as the Myers-Briggs Type Indicator, can assess whether an individual will make a good project manager. By undertaking these assessments, an individual can analyze their personality and connect their personality type with a particular type of career. The Myers-Briggs Type Indicator (MBTI) assessment is incredibly popular for doing just this. The Myers-Briggs Type Indicator (MBTI) is an assessment technique that gives the participant 4 individual letters that are designed to match their personality type. This classification is set out below: Extrovert v. Introvert, Sensing v. Intuitive, Thinking v. Feeling, and Judging v. Perceiving. The research database shows that leaders mostly fall into the ENTJ category (extrovert, intuitive, thinking, and judging). ENTJs are especially well-suited to be leaders and organization builders. They have the ability to clearly identify problems and innovative solutions for the short and long term well-being of an organization(BSM Consulting, 2000). A project manager would generally fall into the category of ESTJ. They are good at a lot of different things, because they put forth a tremendous amount of effort towards doing things the right way. They will be happiest in leadership positions, however, because they have a natural drive to be in charge. They are best suited for jobs which require creating order and structure (BSM Consulting, 2000). The Keirsey Temperament Sorter is another technique that can also be used to determine personal characteristics and aid people gain new understanding of their traits, motivations, and behaviours (AdvisorTeam, 2003). The temperament sorter is an assessment to analyze one specific aspect of ones personality: temperament. Temperament is a set of inclinations that each of us is born with, its a predisposition to certain attitudes and actions (AdvisorTeam, 2003). The four temperaments that people will fall into are artisans, guardians, idealists, and rationals. These groupings have the following characteristics: 1 Artisans value freedom and spontaneity. They want to be without constraint, at liberty to act on their impulses, play and create. Guardians value belonging to a group or community. They maintain stability through responsible, conservative, traditional behaviour. Idealists value personal growth, authenticity, and integrity. They yearn to develop themselves fully as individuals and to facilitate growth in others. Rationals value competence and intelligence. They strive to learn, know, predict, and control the resources in their environment. It has been shown through research that project managers and leaders will most likely fall into the category of either Rational or Guardian (Dittman et al., 2004). A Rational tends to be pragmatic and organized. Their organizational and coordinating skills tends to be highly developed, which means that they are likely to be good at systematizing, ordering priorities, generalizing, summarizing, and at demonstrating their ideas (Prometheus Nemesis, 1998). Guardians tend to be very specific in their communication and reliable when it comes to completing tasks. They also are very cooperative with implementing goals and good at supervision and protecting their subordinates. The Supervisor Guardian is the type of that most fits the personality of the project manager. Supervisor Guardians go by experience, not speculation and experimentation, and certainly not fantasy. They keep their feet firmly on the ground and make sure that those under their supervision do the same (Prometheus Nemesis, 1998). The personality assessments described above are good tools to examine an individuals personality type and compare it to that of the typical project manager career. Each assessment can be used separately or they can be used in conjunction to get the best results. Using these evaluations, it can be shown whether a person has the requisite skills to be a good project manager, and decisions can be made whether to put them in that role, whether they would need further training to be successful in the project manager role, or whether they would be best placed in a different career altogether. 4.0 Conclusion As can be seen an individuals personality can be measured or assessed using the techniques detailed above. These techniques enable organisations to eliminate individuals rather than select individuals as project managers. The methodology behind these techniques would indicate that project managers are born rather than made as the characteristics used to describe individuals are those of an innate nature rather than a derived or coached one. However on the other side of the equation the technical skills required by a Project Manager can be learned and need not necessarily be inherent in the individual. So it could also be concluded that a project manager can be made through learning alone. The leadership style theories above look at the science or art of project management depending on the school to which an individual ascribes to. If an individual is of the viewpoint that Project Managers are born with the innate capabilities to be a project manager then Project Managers have to be viewed as artists. However if the conclusion is that project managers can be taught and trained then they should possibly be viewed as scientists. These can be viewed as two conflicting views with those of a scientific inclination believing that project managers are made and those of a more artistic inclination believing that they are born. From the research undertaken above there is no definitive answer to this question. In the case of Project Management, where there are so many human variables there can be no comprehensive training course that will detail a case study for every given scenario. This would indicate that Project Managers can be and are made but that the best and most effective Project Managers are born.

On June 24th, 2004, this standard been uses to replaces the previous security specifications, Wired Equivalent Privacy (WEP), which was shown to have severe security weaknesses. Wi-Fi Protected Access (WPA) had previously been introduced as a solution to WEP insecurities. WPA implemented only a subset of IEEE 802.11i. WPA2 makes use of a specific mode of the Advanced Encryption Standard (AES) known as the Counter Mode Cipher Block Chaining-Message Authentication Code (CBC-MAC) protocol (CCMP). CCMP provides both data confidentiality (encryption) and data integrity.

As mentioned in the case, treatments of the following items under IFRS and U.S. GAAP are different: Foreign exchange gains and losses Capitalization and revaluation of property, plant and equipment Exchange of assets Impairment of long-lived assets Capitalization of interest on investment in associates Goodwill amortization Companies included in consolidation Related party transactions (Refer pp.5-77 – 5-82) Treatments of depreciation of revalued property, plant and equipment, and disposal of property, plant and equipmentseem to have a significant impact on reported profit 3.U.K. readers of the financial statements may not find them very useful, as the information is not reconciled to the U.K. GAAP. There are differences between U.K. GAAP and IFRS, and between U.K. GAAP and U.S. GAAP. With the adoption of IFRS in the EU, this may not be a major problem anymore. However, UK companies use IFRS as adopted by the EU which in some cases differs from the IFRS issued by the IASB. 4.U.S. readers should find the information useful. However, it would be better for them if the information was reconciled directly from PRC GAAP to U.S. GAAP. 5.When a company is listed on a foreign stock exchange, it is always useful to explain the differences, if any, between accounting standards used in  preparing financial statements, and those that are stipulated by the listing requirements. The need for such explanation is reduced if the two sets of standards are comparable. However, differences can still exist due to different interpretations of the requirements. Therefore, the approach taken by CPCC can be recommended to other companies.

The Ethical Principles in Health Care Organization Essays

The Ethical Principles in Health Care Organization Essays The Ethical Principles in Health Care Organization Paper The Ethical Principles in Health Care Organization Paper For decades, the American system of health care has relied primarily on employer-sponsored insurance programs as a gateway through which individual’s access health care services. Gaps have been filled in through public insurance programs – such as Medicare, Medicaid, the State Children’s Health Insurance Program (SCHIP) and other more locally-based programs – to cover elderly, disabled and certain low income populations who cannot access the employer-based market. In addition, the government (federal, state and local) provides certain limited subsidies (e. g. , tax deductions for the self-employed) for individuals to purchase insurance policies in the private market on their own. While this system has worked effectively for many Americans, it has left behind a significant number – approximately 42 million – who lack any form of health insurance coverage. For these individuals, the country has developed an institutional health care safety net to ensure that they nevertheless receive access to needed care. This institutional safety net is comprised of the many hospitals, clinics and individual providers who serve all who seek their care without regard to ability to pay. Most of these providers receive some support for the uncompensated care they provide through various public programs (on the federal, state and local levels). America has long relied on this two-tiered approach to addressing the problem of the uninsured: expanding access to insurance coverage while providing financial support to safety net providers serving the uninsured. Some policymakers prefer to emphasize coverage over institutional support for providers, others might tip the balance in the other direction. But the two strategies are inexorably linked: if we do not expand insurance coverage we will need a strong system of safety net providers to serve the higher number of uninsured; conversely, if we do not adequately support safety net providers we will need to ensure that individuals can get care on the private market meaning they will need coverage. NAPH supports strong public policy in both arenas. We believe that all individuals should have access to health insurance coverage. Universal coverage is and should be the ultimate goal of health policy in this area. However, even under a system of universal coverage there will always be individuals who, for whatever reasons, fall through the cracks and remain uninsured. For these people, it is imperative that a strong and viable system of safety net providers be available to ensure that care is provided even for those without the means to pay. For America as it enters the twenty-first century, these realities mean that we should be expanding coverage – even if incrementally – however and wherever we can. And we should be providing financial and other support for our safety net providers so that they may continue to meet the needs of the uninsured. Expansion of coverage and preservation of the safety net – these are the dual goals of NAPH policy on the uninsured.

In the Early Renaissance, artists and scholars were incorporating the values and ideals of Ancient Rome and Greece into the growth that became important concepts of the High Renaissance. Donatello made his own place during a time when sculpture was in transition from Gothic traditionalism to classical realism. During the Gothic period, art and sculpture depicted Christian ideas. In Donatello's lifetime (1386? -1466), the patrons of sculpture were still primarily interested in church purposes, but the new trends in style were being influenced by realism. This stylistic realism drew strongly from classical forms to depict human endeavors and emotions. Donatello developed artistic trends appearing at the time by expanding on the humanistic qualities, mastering the depiction of realistic expressio n and perspective in his sculptures, and refusing to compromise his ideals for the sake of conventional patrons. The church’s hold on daily life and thought was changing. Even though Donatello was not the only influential artist of the time, some others were Nanni di Banco, Ghiberti, and Brunelleschi; Donatello led them in revolutionizing the ideals of art.

At the end of June 2003, the Federal Reserve cut interest by a Essay

At the end of June 2003, the Federal Reserve cut interest by a quarter-point to 1.0 per cent, their lowest level in 45 years. Explain the three main channels by - Essay Example f the aggregate demand in the economy, - consumption, investment and government spending, these appear to be the three main channels, through which interest rate influences aggregate demand. The decrease of the interest rates accounting other factors being stable, leads to the increase of the new equipment among firms, which they plan to purchase, it also increases the number of new houses, and the goods of long-term use. Changes in the price levels through the impact on the amount of money in use also influence interest rates. Changes in the interest rates, caused by the changes in the price levels, changes the aggregate demand on goods and services; however, in graphic form this does not make the aggregate demand curve shift; it only reflects the movement along the already existing line. (Handa: 2000) However, interest rates also create another impact. No matter what may be the reason of the interest rates change, their level impacts aggregate demand as a whole. Separately from the price level change, the aggregate demand curve shifts with the changes in interest rates. For example, if the government comes down to the higher expenditures and loans to cover the deficit, with the other conditions stable it leads to the increase of interest rates and negatively influences the plans of expenditures for the firms and individuals. If the supply of the finances for loans increases abroad, the interest rates stay stable, keeping aggregate demand from decrease. (Handa: 2000) Consumption is the most considerable part of the aggregate demand, and it is wise to start the discussion of the interest rates decrease with the impact it creates on consumption. Individuals acquire their incomes in the form of salary, and the capital profits. A portion of the income is spent for paying taxes to governmental structures. On the other hand, government also provides individuals with subsidies (social insurance, unemployment payments, etc.). The decision about consumption lies in the

International law and organisation Essay Example | Topics and Well Written Essays - 1500 words

International law and organisation - Essay Example Since there is no common governing power that supervises all countries, despite the existence of international organizations such as United Nations, states find themselves unable to trust each other. Thus, they usually treat each other as possible opponent that could grab them anytime. On the other hand, the modified structural realists believe that since there is anarchy in international relations, the weaker states have to look for means in order to protect its security and interest, as opposed to the powerful states, which tend to resist regulation or control of their movements. Similar to the modified structural realists, neo-liberal institutionalists believe that adherence to international legal principles would help promote transparency in international dealings, reduce transaction costs in international trade, intensify strict monitoring and enforcement of contractual obligations, and eases imposition of penalties for violation thereof. Voluntary observance of the international legal principles would encourage more cooperation in the international arena that would somehow grant long-term benefits, especially in the financial aspects. The hegemonic stability theor... e theories point to only one thing: the creation and observance of international legal principles are supported by the quest for protection of self-interest by the international stakeholders. Clearly, an independent state would not want to impose upon itself a rule that would ultimately restrict its freedom, if it will not reap any benefit from it. It cannot be denied that this voluntary adhesion to certain legal principles is no longer governed or motivated by the spirit of altruism. States need to protect themselves. Nobody can do it better than themselves. In the humanitarian aspect for example, every state must choose to create a standard that would protect its people against unwarranted human rights violations. This is especially true in terms of physical violence where no specific ideology or religion could divert or amend the standards for all human beings because of the basic knowledge that all humans are equal in feelings. If a state for example would think of exempting itself from the international standards of human rights, common sense dictates that it should prepare itself for possible retaliation in the most inhumane way since the state itself does not observe any standards for physical violation of its citizens. A classic example on this one is the law on war. The killing of a war prisoner is generally prohibited. If the United States for example would kill an Iraqi soldier who was left by his troops during a fight and who was captivated by the American soldiers would be killed, Iraq would then have every reason to kill an American war prisoner because the United States in this case was the first one to violate the rights of such war prisoner. To create and obey this particular international legal principle is then more of a reciprocal benefit
