Other - Assignment Example Macro decisions may be applied to save his or her life as the law allows. The macro decisions also reflect on the government decision on health related measures despite being controversial in majority of the counties. Secondly, law regulates is a regulatory strategy that is used in most instances like in statutory language which is used in authorizing payments for hospitals. In addition, they determine the kind of systems that are incorporated within the health care system, and which are beneficial to consumer health care. An example the system includes the Medicare regulated reimbursement that a health consumer is entitled to receive. Thirdly, the administrative procedure act which acts to clarify and direct different implementations with the health care centers and towards consumer health. The act is responsible for the numerous implementations like the Medicare and Medicaid that adds value to consumer health. In addition, the act ensures that laws for those who implement and those who are governed by the measures are effective and adhered to (Institute of Medicine (U.S.)., 2003). 2. Determine if there have been mergers or closing of hospitals in your area in the last several years (anywhere in the U.S) explain those closing/mergers in the context of the materials. In my area, hospitals are merging with the intent of increasing their productivity towards consumer health. This has caused us heavily because of the increased cost of Medicare services offered by this merged hospitals. However, it is noted that the merged hospitals provide quality care and increased savings as patients are correctly diagnosed and treated before their conditions worsens. Most hospitals in my area that have merged have done due to fear of not surviving independently. They believe that by merging, resources are pooled together thus quality of services offered at the merged center is improved. Thus, merging expands and increases the utilization of hospitals in my area by increasing th e diversity of the services offered. Most hospitals that are merging in my area are taken over by larger hospitals who posses the potential to improve the equipments and services offered by purchasing new products and employing more and qualified staff to serve patients suffering from different ailments (Kaplan, 2000). 3. Select a health care market and describe how it deviates from the perfectly competitive model and recommend policies that could repair the deviation(s) from completion you identified. The free health care market deviates from the perfectly competitive model due to the numerous government interventions. When the government interferes with the free health market then resources are not accurately allocated due to biasness. Some of its rules and regulations are also not conducive for perfectly competitive model because health resources are allocated optimally. The government in most cases deems a free health care market not to be suitable to an ideal health care system as it is not sufficient enough to allocate the health care resources adequately. To stop the government from interfering in the free health care market, I will recommend the free markets to form a law that determines the level to which they can allow the government to interfere in their activities. This is because the government does not create free markets, but they have the

Among the many emerging ISs, the technological or virtual concept of Cloud Computing can provide optimum benefits to the business firms who are using that concept, or if aptly said, are part of the â€Å"Cloud†. At the same time, this Cloud Computing is also positively

Human Resources Management Essay Example | Topics and Well Written Essays - 750 words

Human Resources Management - Essay Example It offers new â€Å"lenses on the tacit and evolutionary aspects of HRM and the value to create† (Berman et al, p, 59). HR is a huge field that begin, creates a policy, carries out and finishes with a continuing solution. To manage Human Resources appears to be extremely simple, although when it comes to be the player then begins the actual problem in dealing with it. It is always trouble-free to give emphasis to a person â€Å"or to that matter anyone about anything† (Berman et al, p, 192). Nonetheless, the greatest is valued at all times. HR in a corporation is constantly available to every one of them regardless of the levels. To begin or make the initial progress, it is the HR division that everyone must get in contact with. They manage the guiding principles and methods within the business for which â€Å"it would have been a year, to do so; provided the focus is on to Quality processes† (Berman et al, p, 221). HR processes incorporates (1) selecting and hir ing staff; (2) guidance and progress; (3) recompense and remuneration; (4) performance appraisal method; and (5) worker relationships. Thorough HR scheduling connects individuals’ management with the company’s duty, image, objectives and aims, in addition to its strategic arrangement as well as budgetary funds. A main objective of HR scheduling is to acquire the accurate amount of individuals with the correct expertise, understanding as well as competencies within the accurate careers on the correct time and at the accurate expenditure. The stress is on connection to strategic scheduling as well as business scheduling in the initial sentence, and the stress is on the planning as well as arrangement of personnel and workers in the final sentence; the procedures through which administration guarantees the correct human resources that are competent of carrying out those assignments that facilitate the business to achieve its goals. Human resource scheduling is the develop ment of human resource tasks, or â€Å"in other words, planning how human resource management will be executed† (Noe et al, p. 123). Therefore, to all intents and purposes, HR scheduling is the expansion of plans in these regions or within similar regions. One might want to extend his personal list related to the business - a record that reveals the functions that HR does within the business. Several individuals connect human resource scheduling with what big businesses do. That is for the reason that, more or less by obligation, big businesses requires to have a lot more proper as well as broad approach to HR scheduling due to their â€Å"size and the intricacy of their businesses† (Noe et al, p. 153). That said, even a company owner having a small number of workers have to consider different employees and human resources concerns. â€Å"Several small company owners do this without really thinking about it† (Noe et al, p.235). For instance, a small company owne r has to consider as well as plan regarding what benefits to present, how to supervise development of personnel, how to forecast the number of employees that are required, how to assess worker performance, and so on. There are five stages of strategic orientation. All build on the earlier one, offering a road map and an assessment of development towards strategic orientation. The five stages are â€Å"(1) involvement in strategic discussion; (2) strategic development; (3) strategic size; (4) creating a strategic

Three phenomena that changed the modern world in the most significant Essay

Three phenomena that changed the modern world in the most significant ways over the past 500 years - Essay Example In the international market, only companies that have implemented superior strategic operation management emerge above the competition. Capitalism is an aspect, which contributes to the elimination of individualism. This is because capitalism is concerned with industrialization whereby human labor is eliminated in the production of goods and services. The machines, plant and machinery take the place of human beings in the production of goods and services. In this regard, the human aspect is eliminated hence affecting individualism. Capitalism emanates from the innovativeness of personnel and division of labor (Getz, Hoffman & Rodriguez, 2009, p.45). This is manifested in the pin industry illustration featuring the division of labor contributions to the increase in productivity of firms. Division of labor leads to invention of plant and machinery and other equipment, which are essential in a capitalist economy. According to Smith, the welfare of the workforce ought not to be given the first priority. Capitalism also shifts relevance from the welfare of employees to the production units. This is because the move deprives their human dignity. It is true that use of money gives satisfaction to the final consumers of commodities. This owes to the fact that consumers prefer saving as opposed to expenditure. Human labor provides utility to the consumers. The reliance on equilibrium in charging the consumers is controversial. Capitalism does not recognize the plight of the laborers within an industry. Therefore, the labor the workforce provides is not the ultimate satisfaction for the company but a means to an end. Capitalism requires many people to work for a common goal and benefit (Getz, Hoffman & Rodriguez, 2009, p.49). The welfare of human beings in capitalism is valuable so long as it adds value in the progression of an industry’s productivity. This is because material development is usually ensured at the

Satellite. Solar system Essay Example for Free

Satellite. Solar system Essay A satellite is defined as any object that orbits any other object. Satellites can be celestial, such as a moon orbiting a planet in the solar system, or a planet in the solar system orbiting the sun. Satellites can also be man-made. Man-made satellites are typically launched into outer space from earth to collect data, photos and other information about Earth and all the many things that exist around it. An animation depicting the orbits of GPS satellites in medium earth orbit. A full size model of the Earth observation satellite ERS 2  In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavor. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. The first artificial satellite, Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. These originate from more than 50 countries and have used the satellite launching capabilities of ten nations. A few space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Venus, Mars, Jupiter and Saturn. Satellites are used for a large number of purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and research satellites. Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit. Satellites are usually semi-independent computer-controlled systems. Satellite subsystems attend many tasks, such as power generation, thermal control, telemetry, attitude control and orbit control. HISTORY OF ARTIFICIAL SATELLITES Sputnik 1: The first artificial satellite The first artificial satellite was Sputnik 1, launched by the Soviet Union on October 4, 1957, and initiating the Soviet Sputnik program, with Sergei Korolev as chief designer. This in turn triggered the Space Race between the Soviet Union and the United States. Sputnik 1 helped to identify the density of high atmospheric layers through measurement of its orbital change and provided data on radio-signal distribution in the ionosphere. The unanticipated announcement of Sputnik 1s success precipitated the Sputnik crisis in the United States and ignited the so-called Space Race within the Cold War. Sputnik 2 was launched on November 3, 1957 and carried the first living passenger into orbit, a dog named Laika. TYPES OF SATELLITE ïÆ'ËœCommunication satellites †¢Communication satellites provide a worldwide linkup of radio, telephone, and television. †¢The first communication satellite was Echo 1, launched in 1960. †¢Relay 1 and telstar 1 were the first active communications satellites. †¢They were launched in 1962. ïÆ'ËœNavigation satellites †¢Navigation satellites are mainly intended to help aircraft, ships and nuclear submarines. †¢These satellites provide constant signals by which aircraft and ships can determine their positions with great accuracy. ïÆ'ËœWeather satellites †¢Weather satellites carry cameras and other instruments pointed toward Earths atmosphere. †¢They can provide advance warning of severe weather and are a great aid to weather forecasting. ïÆ'ËœMilitary satellites †¢ Many military satellites are similar to commercial ones, but they send encrypted data that only a special receiver can decipher. †¢ Military surveillance satellites take pictures just as other earth-imaging satellites do, but cameras on military satellites usually have a higher resolution. ïÆ'ËœScientific satellites †¢Earth-orbiting satellites can provide data to map Earth, determine the size and shape of Earth, and study the dynamics of the oceans and the atmosphere. †¢ Scientists also use satellites to observe the Sun, the Moon, other planets and their moons, comets, stars, and galaxies. HOW ARE SATELLITES LAUNCHED ïÆ'ËœThe trick when launching a satellite is to get it high enough to do its job without losing the capsule to outer space. ïÆ'Ëœ Its a delicate balance of push and pull, accomplished by the inertia of the moving object and the Earths gravity. GEOSYNCHRONOUS SATELLITE LAUNCH VEHICLE ïÆ'ËœThe Geosynchronous Satellite Launch Vehicle (usually known by its abbreviation, GSLV) is an expendable launch system operated by the Indian Space Research Organization (ISRO). ïÆ'ËœIt was developed to enable India to launch its INSAT-type satellites into geostationary orbit and to make India less dependent on foreign rockets.

The inertial systems are developed by ISRO Inertial Systems Unit (IISU) at Thiruvananthapuram. The liquid propulsion stages for the second and fourth stages of PSLV as well as the reaction control systems are developed by the Liquid Propulsion Systems Centre (LPSC), also at Thiruvananthapuram. The solid propellant motors are processed by Satish Dhawan Space Centre SHAR, which also carries out launch operations. After some delays, the PSLV had its first launch on 20 September 1993. Although all main engines performed as expected, an altitude control problem was reported in the second and third stages. After this initial setback, ISRO met complete success with the third developmental launch in 1996. Further successful launches followed in 1997, 1999, and 2001. PSLV continues to be the work horse of Indian satellite launches, especially for LEO satellites and the Chandrayaan Projects. It has undergone several improvements with each subsequent version, especially those involving thrust, efficiency as well as weight. ORBIT ïÆ'ËœAn orbit is a regular, repeating path that an object in space takes around another one. ïÆ'ËœAn object in an orbit is called a satellite. A satellite can be natural, like the moon, or human -made. ïÆ'ËœIn our solar system, the Earth orbits the Sun, as do the other eight planets. ïÆ'ËœThey all travel on or near the orbital plane, an imaginary disk-shaped surface in space. ïÆ'Ëœ All of the orbits are circular or elliptical in their shape. In addition to the planets orbits. HOW A SATELLITE STAY IN THE ORBIT ïÆ'ËœThe forward motion of the satellite is its momentum. If the gravity of the earth is not acting on the satellite, the satellite would continue in one direction. ïÆ'ËœThe swinging of the satellite gives it its forward motion. ïÆ'Ëœ When these two forces are equal, the satellite remains in orbit, without falling into or flying away from the Earth. ïÆ'Ëœ A satellites forward motion is controlled by rockets. ïÆ'ËœWhen the rockets are not fired, inertia keeps the satellite going in one direction. HOW SATELLITES WORK ïÆ'ËœReceiving uplinked radio signals from earth satellite transmission stations (antennas). ïÆ'ËœAmplifying received radio signals ïÆ'ËœSorting the input signals and directing the output signals through input/output signal multiplexers to the proper downlink antennas for retransmission to earth satellite receiving stations (antennas).

Abortion: An Ethical Issue

Abortion: An Ethical Issue Abortion means terminating pregnancy. Abortion is widespread now days all over the world. Abortion is the most controversial subject when it comes to ethical issue. Ethical issues in abortion involve a constant battle between freedom and life. As per the article given in website www.bbc.co.uk/ethics/abortion, there are two groups of people: Pro-choice and Pro-life. Pro-choice people are for freedom. They consider it unethical to take away a womans right to decide over their own body. While pro-life people are for life. They consider it unethical to kill a growing life. Lets discuss in detail of both views. Prochoice people regard right to control ones own body as a key moral right. If women are not allowed to abort unwanted feotus they are deprived of this right.The foetus exists inside a womans body. A woman has the right to decide whether the foetus remains in her body, therefore a pregnant woman has the right to abort the foetus Pro-life advocates say that the right to life should always outweigh the right of an individual to equality or to control their own body. They raise arguments that abortion does not liberate women, but allows society not to cater to womens needs. They say that what women need for equality is not free access to abortion but to be given what they need to survive financially and socially as mothers. Further they hold that foetus is not a part of womans body like liver, kidney, lungs. It is a saperate Person inside the womb.Abortion means killing a human being or murder. Here they raise question that why woman or couple did not take precaution instead ? Why an innocent life is killed for someone elses mistake ? This also justifies the anti-abortion argument. Apart from Pro-life advocates there are other view against abortion like it is against feminist principle of justice, non-violence and non-discrimination. Another group objects abortion as they see it as a men plot. They argue that men see the risk of pregnancy as something that stops men having sex when they want it. If men are to achieve full sexual freedom it is essential that abortion be freely available to backup contraception. Summary: The issue of abortion is the most controversial issue. The advocates of Pro-life and Pro-choice have their own justifications. Pro-choice advocates hold that it is their right to have control over their own body. Pro-life advocates hold that from the very conception life start in the womb of a woman. It is actually a Person inside the womb. So, the question remains, Pro-life or pro-choice ? Critical analysis and evaluation of argument The fight between pro-life and pro-choice is an everlasting battle and the ethical dilemma. Lets analyze the arguments in context of two major philosophical theories: Teleological Theory and Deontological Theory, taken from the source: website: www.socyberty.com/Issues/Abortion-An-Ethical-Analyses First take a look at abortion from a Teleological point of view, it depends solely on consequences. Teleological theory is basically a Utilitarianism formulated by Jeremy and John Stuart Mill. This approach to morality and ethics hold that there is no universal basis for determining what is right. Main idea behind it is the principle of Utility. The principle focuses on the consequence of action, intentions are irrelevant, therefore breaking promise, lying, causing pain or killing someone may under certain circumstances be the right action and in other circumstances, wrong action. Applying this theory into the topic of abortion, question arises: Do I really need a child ? Am I ready for a baby ? Do I really want to give up all of my time to raise a baby ? or What if I am unhappy with a child. This theory seems to focus on a very selfish viewpoint of the situation. Utalitarian theory does not mean that a woman is selfish on her decision of abortion. Lets say a woman decides to have an abortion because she is not propared to have a child, she has no support: financial or emotional and she is still in school. The woman decides that it would be in her best interest to have abortion at this point. This woman can remain in school and not have to worry about bringing unplanned child, but just because this decision worked out well for her, was it the right decision ? Although this might seemed like a good decision, it still brings concerns and ethical dilemmas to our attention. Could she not have had child , found employment and stayed in school (as most people do)? Could she not have ultimately ended up being the happiest she has ever been because of this child coming into her life ? It might seem easy to determine ones own self interest, but do we sometimes take advantage of the choices we are given ? This question brings the case in the light of Deontological Theory. This theory is based on something other then the consequences of a persons actions. This theory has two approaches: Divine command Thoery and System of duties. Thomas Aquinas (1274-1275) was the proponent of Divine command theory. According to him the world is created by God. Whatever happens, happens with the will of God. Life is given and taken by him only. Human being doesnt have any right to take anyones life. A woman who followed the Divine Command theory might have done things differently in the same situation. She might not have based her decision on self interest, nor on consequences, but rather on something higher like God. God has given her this child to birth and care for. This also face criticism like how can we base a life altering decision on the belief that there is a higher power, God ? Immaneul Kant (1725-1805) is the leading proponent of Deontological Approach in decision making.. He formulated a System of Duties: Perfect duties and Imperfect duties. Perfect duties are to be followed in all circusmstances. In Perfect duties he mentions Not to kill an innocent person. Taking the pregnant womans case in this context, There is a Person inside her womb. From the time of conception in the womb, the child is, not just another part of the mothers tissue, but a saparate person. Abortion means killing of that Person. This faces critism that at the time of conceiving there is a just formation of cell having few tissues. Cells are created and destroyed continuously in our body. Both of these situations determine very different viewpoints, but how do we know which theory can be considered ethically moral ? There are many possible reasons a woman might choose to have an abortion, for example: to avoid interruption of life goals, the pregnancy is a result of rape, or to prevent birth of abnormal or diseased child, just to name a few. It is also obvious why some may consider abortion to be morally problematic, whether the reasons are based on religion, and the values of life. The truth is that each one of us is forced to decide how we feel about abortion, as we are with any ethical issue. So, the question remains, Pro-life or Pro-choice ? Personal Position: I personally feel that a woman should have the right to choose when it comes to abortion, but I will contradict myself under certain circumstances. In certain scenarios, the choice of abortion can be justified , but what about those who are just pure careless ? What about those who act carelessly because they know in the back of their minds that they have another alternative if something go unplanned ? For example: there are many teens that become pregnant because of carelessness in practicing safe sex. If these young girls knew that if they became pregnant, they had no option but to keep the child, would they be more careful ? Or would the number of teens who become pregnant remain the same ? I believe it would decrease.. Utilitarian approach of Teleological theory allows us to consider the Utility of child, it allows us to have second chance (abortion) should we make mistake or put health of ourselves at risk and kill unborn child. Divine Command theory does the exact opposite, it opens our eyes to new life, it leads us to believe that morality is based on God and the child was given to us by God. It also allows us to believe if our child had a deformity or disease, that it was meant to be and it is what makes our child special. It perceive us to believe that abortion would be wrong because the child was sent to us for a reason. So can abortion be ethical ? In my opinion, yes it can. It can be ethical when the choice is not being taken for granted. In conclusion, my research lead me to believe that while we have different theorys to agree or disagree with, abortion is a choice. I feel that when it comes to a decision of this kind, the ethicality of the situation is left only to that individual. As long as the women is presented with all options and alternatives, and she has the right to choose what she feels is best, regardless of our own personal feelings or religious beliefs towards abortion.

The Tailless Aircraft

The Tailless Aircraft This report on tailless aircraft presents the pros and cons of using such an aircraft design for commercial purposes. The report comprises 4 sections discussing the aerodynamics, structural innovations, engines and overall advantages and disadvantages of tailless aircraft. The aerodynamic study of a tailless aircraft highlights the importance of the wave drag and span loading distribution and different designs that can improve the aerodynamic performance effectively. In structural innovations, several existing tailless aircraft are examined to identify how the structures have been designed to create a successful aircraft. In particular, structures used in the control and stability of the aircraft are examined. As regards to engines, the positioning of the engine and the idea of using a Vertical Takeoff has been discussed. The advantages and disadvantages of a tailless aircraft have been detailed. Introduction Of the aircraft in use today, the vast majority use a tailplane to house rudder and elevators. Aircraft without such a system remain quite rare. However, the concept of tailless aircraft has long been considered by engineers and aviators as an aerodynamically ideal. In the history of the aircraft design several attempts were made to build an aircraft with reduced tail size which has sometimes resulted in smaller drag and weight but has added to controllability problems. Because of this, tailless designs have mostly been used in military applications. In this report we assess whether it is now possible to seriously use this concept in commercial aircraft. Methodology The information contained in this report was primarily gathered from textbooks and internet research. Four different aspects of the subject were identified and each aspect was researched and written up by one member of the group. Additionally, the group were able to examine a harrier jump jet which visited Perth on 7th May 2010. Results of findings The following table summarises what the research has revealed: Negative points Lower profile and interference drag Lift to drag ratio increases by 20-25% Engines can be positioned in the centre rear instead of a tail, providing the additional advantage of directional stability Roll control is more efficient due to large wingspan The tip of the wing aerofoil is not near the stall angle due to backward sweep along with twisted wing tip Vertical takeoff is not practical since a large commercial aircraft weighs too much for the thrust available from current engine technology to overcome Directional control is more difficult to achieve without adding a rudder assembly The triangular spanwise aerodynamic loading distribution does not give the best aerodynamic performance even though the wave drag is the reduced. Section 1: Aerodynamics This section of the report discusses the aerodynamics of a tailless aircraft and various factors affecting the same. A tailless a is a revolutionary conceptual change from the classical design that has been prevailing for the past 50 years i.e. a wing attached to a cylindrical fuselage with a tail to ensure the stability and manoeuvrability of the aircraft. Lower wetted area (area which is in contact with the external airflow) to volume ratio and lower interference drag is the main aerodynamic advantage of a tailless aircraft in comparison with the conventional aircraft. On the aerodynamic performance side, the maximum lift-to-drag ratio depends on the ratio of the aircraft span to the square root of the product of the induced drag factor and the zero-lift drag area, which is proportional to the wetted area of the aircraft. () max = Where Cf is the average friction co-efficient (mainly dependent on the Reynolds number) over the wetted area Swet and is the friction co-efficient. Since the tailless aircraft have a lower aspect ratio but also a lower friction co-efficient due to its larger chord, we always get smaller relative wetted area. This provides a substantial improvement in aerodynamic performance by increasing the lift-to-drag ratio of tailless aircraft in cruise to about 20-25% as compared to the conventional aircrafts. The BWB-450 and BWB-800 were designed to compare with the existing fleet of conventional aircrafts as Boeing 747 and Airbus 380. BWB-450 was presented with the span and the aspect ratio being reduced to 80 m and 7.55 respectively, thereby concluding a decrease in 30%fuel burn per seat for the BWB models as compared to other conventional aircrafts and thus requiring 3 instead of 4 engines. Moreover another such design project was successfully completed, which is based on a similar payload and performance as Airbus 380 with over 650 passengers. The configuration of the project is well suited for the application of laminar flow technology (which results in skin friction drag) to the engine Nacelle and potentially to the lifting surfaces. Also an increase in cruise Mach number increases the drag making the design of aircraft unfeasible.
