Taxing The Internet Essay, Research Paper With the Internet turning in popularity every twenty-four hours, traffic on the Internet has doubled every 100 yearss ( NCPA ) ; the idea of taxing the Internet has become a het treatment. Advocates of the revenue enhancement say it will bring forth big net incomes for local and province authoritiess through gross revenues revenue enhancement. While oppositions province that the populace has become accustomed to non paying revenue enhancements online, and that taxing would decelerate the rapid growing of Internet commercialism. The Clinton disposal has decided non to revenue enhancement minutess made over the Internet # 8212 ; for the clip being. Clinton advisor Ira Magaziner says the Net should be tax-exempt for at least five old ages. Presidential campaigners seem to hold besides aligned together to plight how they would halt the tax collector immersing his Myxocephalus aenaeus hands into internet. In some respects, a farther prohibition on new Internet revenue enhancements is neither here nor at that place, because the existent job is the trouble of roll uping those old revenue enhancements that should already use to e-commerce.

The Internet has been responsible for a one-percentage-point bead in rising prices and is turning twice every bit fast as the overall economic system. A study from the Department of Commerce recommends that electronic commercialism non be # 8220 ; burdened with extended ordinance, revenue enhancement or censoring # 8221 ; ( NCPA ) . Those who oppose Internet revenue enhancement predict that any move to roll up such revenue enhancements would drench the tribunals with cases over legal power. Another point made by oppositions of Internet revenue enhancement provinces that if a gross revenues revenue enhancement were implemented, on-line Sellerss would merely travel offshore. Besides states without gross revenues revenue enhancements gain economically ; Oregon, for illustration, is already outpacing provinces with gross revenues revenue enhancements as the location of pick for Internet merchants. Elimination of a province gross revenues revenue enhancement may bring on concerns to turn up in a province, where revenue enhancements on concern and its employees will finally transcend the lost gross revenues revenue enhancement grosss ( Is Gross saless Tax ) . Historically the huge majority of goods and services people consumed were purchased in the immediate locality, so a gross revenues revenue enhancement made sense. However, two developments are changing the basic premise on which the gross revenues revenue enhancement remainders, growing of gross revenues over the Internet and turning portion of end product that is in the signifier of services, instead than physical goods ( . This may non look much of a job now, while the province caissons are overruning with money and e-commerce is in its babyhood. But the longer nil is done, the more clients will go accustomed to avoiding revenue enhancements when shopping online and the more unpopular will be any effort to alter that state of affairs ( Economist ) .

Lost Foam Casting Essays

Lost Foam Casting Essays Lost Foam Casting Paper Lost Foam Casting Paper LOST FOAM CASTING ABSTRACT: The Report presents some theoretical and practical aspects regarding the casting of alloys in lost foam moulds. The stages of the procedure, the economic benefits and several ecological aspects are synthetically presented. KEY WORDS: casting, alloys, lost foam process, Expanded polystyrene Introduction The lost foam casting process offers several advantages over conventional sand casting processes, such as simplified production techniques and reduced environmental waste due to binder system emissions and sand disposal. The process is well-suited for castings with complex geometries, tight tolerances, and smooth as-cast surface finish requirements. When the castings are designed to fully exploit these advantages, cleaning and machining times are dramatically reduced if not completely eliminated. Therefore, the lost foam casting process is viewed as a value-added process rather than a substitute for sand casting. Lost foam castings are produced by pouring molten metal into a foam pattern contained in a flask filled with loose sand that is compacted through vibration. Generally speaking, a foam pattern is coated with a refractory slurry and dried before being placed in the flask and surrounded by large grain fineness sand. The foam pattern degrades immediately after molten metal is introduced, leaving a casting that duplicates all features of the foam pattern. The degradation products are vented into the loose sand. In lost foam casting process, mold filling, thermal transport, and solidification are strongly influenced by the foam pattern degradation. There are three phenomena which are inherent in lost foam casting process: slow molten metal flow, reducing atmosphere, and degradation products. The first and second phenomena help reduce oxides or slag defects. The last one, however, may become casting defects if they remain in the cast parts. To improve lost foam casting design, it is ssential to understand the interactions between the foam pattern and molten metal as well as the displacement of degradation products. History The first patent for an evaporative-pattern casting process was filed in April 1956, by H. F. Shroyer. He patented the use of foam patterns embedded in traditional green sand for metal casting. In his patent, a pattern was machined from a block of expanded polystyrene (EPS), and supported by bonded sand during pouring . This process is now known as the full mold process. In 1964, M. C. Flemmings used unbonded sand for the process. The first North American foundry to use evaporative-pattern casting was the Robinson Foundry at Alexander City, Alabama. General motors first product using these processes was the 4. 3L, V-6 diesel cylinder head, which were made in 1981 at Massena, New York. A study found in 1997 that evaporative-pattern casting processes accounted for approximately 140,000 tons of aluminum casting in the United States. The same survey forecast that evaporative-pattern casting processes would account for 29% of the aluminum, and 14% of the ferrous casting markets in the near future.

The Lost Foam casting process originated in 1958 when H. F. Shroyer was granted a patent for a cavity-less casting method, using a polystyrene foam pattern embedded in traditional green sand. The polystyrene foam pattern left in the sand is decomposed by the poured molten metal. The metal replaces the foam pattern, exactly duplicating all of the features of the original pattern. Like other investment casting methods, this requires that a pattern be produced for every casting poured because it is evaporated (â€Å"lost†) in the process. Schematic of lost for casting Process The essential steps of the lost foam casting procedure are: 1) The execution of patterns, 2) Execution of moulds 3) casting the alloy. Execution of Patterns: A pattern is made from  polystyrene foam (Expanded Polysterene), which can be done many different. What is Expanded Polystyrene? Expanded Polystyrene in its broadest sense is a rigid cellular plastic which is found in a multitude of shapes and applications. Raw Material Manufacturing: Expanded polystyrene (EPS) is the most commonly used foam pattern, it can be produced by bead pre-expansion into polystyrene (PS) beads that are ready for moulding. PS precursors are formed from ethyl benzene through an aluminum catalyst with benzene and ethylene obtained from crude oil and natural gas [Shivkumar, 1994]. Ethyl benzene is then converted to styrene at high temperature with nitrogen gas and iron catalysts. It forms polystyrene when exposed to a peroxide catalyst and polymerized in a water solution [Goria et al. , 1986]. These unexpanded beads have a density of 600 g/l (38 pounds per cubic feet (pcf)) and they are expanded 20~50 times with heat at 100 oC until the desired density is reached [Kanicki, 1985]. Polystyrene (PS) MOLECULAR FORMULA: The C=C double bond in each monomer is transformed into a C-C single bond in the polymer. | Properties: ease of forming, clarity, low heat transfer, good thermal insulation. Density: 1. 03-1. 06 g/ccStatistic: In 1999 PS usage as a plastic bottle resin was essentially nil. | Description: Polystyrene can be made into rigid or foamed products. It has a relatively low melting point. Packaging applications: Plates, cups, cutlery, meat trays, egg cartons, carry-out containers, aspirin bottles, compact disc jackets Recycled products: Thermal insulation, light switch plates, egg cartons, vents, rulers, foam packing, carry-out containers Raw Material Manufacturing: Expanded Polystyrene (foam)  is obtained from expandable polystyrene (beads), which is a rigid cellular plastic which contains an expansion agent. Expandable polystyrene is therefore obtained from oil as can be seen from the diagram. The EPS Manufacturing Process is inextricably linked with the process described in the last section, which brought us from the oil well to expandable polystyrene, now we will see what happens in the transformation process that leads us to Expanded Polystyrene foam parts. We have seen that the raw material is obtained through a chemical process. The next process involves the use of physics and the conversion process is carried out in three stages. 1st stage   PRE-EXPANSION: The raw material (beads)  is heated in special machines called pre-expanders with steam at temperatures of approximately 215-f. The density of the material falls from 40lbs/cu ft to values of usually between 1 ~ 2lbs/cu ft. During the process of pre-expansion the raw materials hard beads turns into cellular (foam) plastic beads with small closed cells that hold air in their interior. 2nd stage   INTERMEDIATE MATURING AND STABILIZATION: On cooling, the recently expanded particles form a vacuum in their interior and this must be compensated for by air diffusion. This is how the beads achieve greater mechanical elasticity and improve expansion capacity, something very useful in the following transformation stage. This process is carried out during the materials intermediate maturing in aerated silos or mesh bags. The beads are dried at the same time. 3rd stage   EXPANSION AND FINAL MOLDING: During this stage the stabilized pre-expanded beads are transported to molds where they are again subjected to steam so that the beads bind together. In this way large blocks are obtained block molding   (that are later sectioned to the required shape like boards, panels, cylinders etc. ) or products in their final finished shape shape molding. Execution of moulds and casting alloy The basic steps to the process include: A foam pattern and gating system are made using a foam molding press * The foam pattern and the gating system are glued together to form a cluster of patterns * The cluster is coated with a permeable refractory coating and dried unde r controlled conditions * The dried, coated cluster is invested in a foundry flask with loose, unbonded sand that is vibrated to provide tight compaction * The molten metal is poured on to the top of the gating system which directs the metal throughout the cluster and replaces the foam gating and patterns * The remaining operations such as, shakeout, cut-off, grinding, heat treat, etc. are straightforward and similar to other casting processes. The series and major steps in lost foam casting (LFC) What metals can be poured in the Lost Foam process? Generally, all ferrous and non-ferrous materials can be successfully cast using the Lost Foam process. Because the foam pattern and gating system must be decomposed to produce a casting, metal pouring temperatures above 1000 °F are usually required. Lower temperature metals can be poured, but part size is limited. In addition, very low carbon ferrous castings will require special processing. What size range of parts can be produced by the Lost Foam process? Lost Foam castings can be produced in most all metals from a fraction of a pound up to thousands of pounds. Slightly more advanced techniques are used for very large castings. What type of tooling is required and at what cost? Typically, tooling is composed of a split-cavity machined aluminum die that is the negative mold from which the foam pattern is produced. The tooling is highly specialized and must be constructed by experienced tooling manufacturers familiar with the requirements of the foam molders and foundries. Most tooling for Lost Foam patterns will compare favorably with permanent and die cast tooling. Prototype and simple tools may be in the $3000-5000 range while high-end tooling for complex or very large parts can be in the several hundred thousand dollar range. As a result of the materials used and the process stresses, Lost Foam tools can be expected to have 3 to 4 times the cycle life of permanent mold or die casting tools. What lead times can be expected when ordering a Lost Foam casting? As with all processes, lead times vary greatly depending on part complexity. Generally, 8 to 16 weeks is typical for completed tooling and first castings produced. After casting approval, 6 to 12 weeks is typical for production run startup. Rapid prototyping methods can produce castings in as little as 2 to 3 weeks. What size range of parts can be produced by the Lost Foam process? Lost Foam castings can be produced in most all metals from a fraction of a pound up to thousands of pounds. Slightly more advanced echniques are used for very large castings. What is the cost of using the Lost Foam process? Lost Foam castings are generally more expensive than forged parts, or parts made by other casting processes. The value inherent in the Lost Foam process v ersus other processes is seen in tighter tolerances, weight reduction and as-cast features which all results in less machining and cleanup time. Many castings that require milling, turning, drilling and grinding can be made in the Lost Foam process with only . 020† . 030† of machine stock. It is imperative that the features to be cast are discussed by all parties to determine the net finished product cost. What quantities need to be made to make the Lost Foam process practical? The answer, simply, is not as many as you would think. Tooling amortization is a key factor in this determination. Potential overall savings for your application will aid in your decision. Generally, 500-1000 pieces per year is the minimum production run to be economical. Prototyping runs, however, may be as few as 3-5 pieces for Fabricated Foam patterns or 20-100 pieces for Quick-Cut CNC machined aluminum tooling. Application Lost foam casting  is used mostly for automotive applications. Cast iron, aluminum alloys, steels, nickel and in some cases stainless steel and copper alloys are cast in this process. The flexibility of LFC is useful in making complicated casting assemblies for automotive and other metal cast like cylinder heads, weldments, pump housing, Manifolds for automobile, machine bases, automobiles of product produce from lost foam casting glmmarine. com/ManifoldArticle. html Superior Marine Manifolds Agricultural Equipment Part / Farm Machinery Part Product Description Detail Feature: Product Name: Agricultural equipment part / Farm machinery part   Materials: Grey iron, Ductile Iron, High Chrome iron, resistent ironcarbon steels, alloy steels, stainless steels, High Manganese steel   Items: FOB NingBo or Shanghai Place of Origin: Ningbo, China Software for specification drawings: PDF, Auto CAD, Solid work, JPG, ProE   Main production equipments: Wax injection, CNC-machine, machine-center, Heat treatment Furnace lost foam casting for yacht gas piping Specifications 1). lost foam casting 2). reliable product quality 3). on time delivery 4). excellent after-sale service 5). 3D design It is designed for the yacht or the ships gas exhaust piping.

Complex castings, particularly internal sections, which require high dimensional accuracy and have thin sections, can be produced very cost effectively in comparison with to conventional sand moulding processes. * Fettling and machining is minimized due to high dimensional accuracy and the absence of parting lines or core fins. * The shakeout process is simplified and does not require the heavy machinery required for bonded sand systems. * High levels of sand reuse are possible. As little as 1-2% of the sand is lost as a result of spills. Periodically a portion of sand may need to be removed or reclaimed to avoid the build-up of styrene. * Complex components can be formed where other casting processes would require multiple components to be assembled. Excellent dimensional tolerances for precision casting. * Lower production cost than traditional Green Sand casting. * Castings can be made from 1 pound up to thousands of pounds with no size limitations. * Lost Foam is an environmental ly friendly process. * The sand is un-bonded and can be recovered and re-used at a low cost. * There is lower capital investment. Disadvantages * pattern costs can be high for low volume application * patterns are easily damaged or distorted due to their low strength. If a die is used to create the patterns there is a large initial cost * The pattern coating process is time-consuming, and pattern handling requires great care. Good process control is required as a scrapped casting means replacement not only of the mold but the pattern as well. What type of tooling is required and at what cost? Typically, tooling is composed of a split-cavity machined aluminum die that is the negative mold from which the foam pattern is produced. The tooling is highly specialized and must be constructed by experienced tooling manufacturers familiar with the requirements of the foam molders and foundries. Most tooling for Lost Foam patterns will compare favorably with permanent and die cast tooling. Pr ototype and simple tools may be in the $3000-5000 range while high-end tooling for complex or very large parts can be in the several hundred thousand dollar range. As a result of the materials used and the process stresses, Lost Foam tools can be expected to have 3 to 4 times the cycle life of permanent mold or die casting tools. What â€Å"as-cast† tolerances can be expected? Typically, a linear tolerance of +/-. 005 inches/inch is standard for the Lost Foam process. This tolerance will vary depending on part size, complexity and geometry. Subsequent straightening or coining procedures will often enable even tighter tolerances to be held on critical dimensions. A targeted effort between the foam pattern producer, the casting producer and the casting user will often result in a Lost Foam casting that substantially reduces or completely eliminates previous machining requirements. Diameter Tolerance 0-1 in. [ or -]0. 007 in. 1-3 in. [ or -]0. 15 in. 3-6 in. [ or -]0. 025 in. In the case of diameters split by glue lines, 0. 005-0. 010 in. should be added dependent on foam size.

[ or -]0. 015-0. 020 in. More than 10 in. [ or -]0. 030-0. 050 in. Flatness can be affected by the foam, foam geometry, molding cycle control and foam removal. True Position Tolerance 0-2 in. 0. 025 in. 2-4 in. 0. 030 in. 4-10 in. 0. 030-0. 60 in. 10 in. 0. 080 in. Limitations 1. For low volume applications, the pattern costs are relatively high, therefore in order to increase the substantial economic benefits and decrease the pattern costs, only bulk quantities should be produced. 2. Due to their low strength, the patterns are very easily damaged and/or distorted. 3. There is a very high initial cost if a die is used to create the patterns. 4. The coating process is very time consuming as the pattern handling requires great care. Design considerations: Ensure that there is adequate material: Insufficient material usually leads to incomplete castings in the manufacturing of parts. It is important to calculate the volume of all areas f the casting while also accounting for shrinkage. Consider the Superheat: Superheat is the temperature difference between the metal at pouring and freezing. An increase in the superheat can increase the fluidity of the material for the casting, which can assist with its flow into the mold. Insulate Risers: The riser should be the last to solidify because it is the reservoir of molten material for the casting. Therefore insulating the top will greatly reduce cooling in the risers from the steep temperature gradient between the liquid metal of the casting, and the room temperature air. Consider V/A Ratios: V/A ratio represents the volume to surface area ratio. In casting, sections with low volume to surface area will solidify faster than sections with higher volume to surface area. It is therefore important to consider the V/A ratios in order to avoid premature solidification of the casting and the formation of vacancies. Heat Masses: Sections of the casting with low V/A ratios should be located further away from the risers as this will ensure a smooth solidification of the casting. It is important to avoid large heat masses in locations distant to risers. Sections of the Casting: A heavy section should not be fed through a lighter one. In the manufacturing process, the flow of material is very important. Prevent Planes of Weakness: After the solidifications of castings, columnar grain structures pointing toward the center develop in the material. This causes the sharp corners in the casting to develop a plane of weakness. This is prevented by rounding the edges of sharp corners. Reduce Tubulence: Turbulence is bad because it traps gases in the casting material and causes mold erosion. It can be reduced by the design of a gating system that promotes a more laminar flow of the liquid metal. FUTURE EPF can safely be incinerated and will yield only carbon dioxide and water if the procedure is handled correctly, but the trend has been to recycle it wherever possible. EPF can be recycled into  concrete,  egg cartons, office products, foam insulation, and garbage cans. Unfortunately, only one percent of the 11 billion kilograms of EPF thrown away each year is being recycled. The National Polystyrene Recycling Company, which consists of seven major corporations, including Amoco, Dow, and Mobil, plans to increase this to 25 percent by 1995 by focusing on big users of EPF- fast food outlets and college dining establishments. Since the Montreal Protocol of 1988, new research has focused on ways to reduce CFC use, and on developing alternative blowing agents that will not harm the ozone layer. Recent developments include a process that uses pressurized carbon dioxide to produce smaller, more uniform cells. These in turn provide a foam that is stronger and smoother than earlier foams. All this will bring us an uns are U. S. Department of Energy and metal casting industry industries of the future (IOF), University of Alabama-Birmingham and over 30 universities and industry partners. This strategy has significantly improved the use of LFC in the past years. Emphasis is based on universities research with strong industry participation. The direct results of LFC researches are quickly applied by these positioned partner industries and results from the various applications are evaluated and analyzed. 2. Another strategy used is introducing hundreds of students to metal casting industries were they are well trained and becomes more innovative bringing latest technical knowledge and processes. this has tremendously improve state-of-the-heart technology in improving LFC in the past years. 3. Material(s) selection requires a specific type of manufacturing process(s) and different type(s) of casting techniques. The casting materials specific heat as well as that of the mold material will be influential in controlling the thermal gradients in the system. e. g. melts  fluidity and flow. A material high heat of fusion will take longer to solidify and may improve flow characteristics within the casting. 4. Gases being expelled by the material during solidification can be eliminated by a proper venting system in the mold. This can be planned out during the manufacturing design phase of the casting process. WAYS TO IMPROVE LOST FOAM CASTING 1. Development of computational fluid dynamics tool for modeling the blowing and steaming of expandable polystyrene (EPS) pattern for lost foam casting(mathematical tool). it allows analytical approach to systematically design EPS pattern molds that produces higher quality pattern with reduced lead-time and expense. arena-flow. com 2. Reduction of porosity and fold defects has improve production efficiency, mechanical properties and marketability of lost foam casting. 3. The combination of LFC with 3DP (three dimensional printing) to eliminate machining of mold contours and manual process of drilling and finishing steam holes, i. e. repeatedly printing thin layers of bonding materials on a thin layer of powder to build up a tool(mould) shape from computer-aided design(CAD) 4. Complex and detailed passages and other features are cast directly e. g. oil galleries, crank case ventilation channels, oil drain back passage, coolant passage etc are cast directly into cylinder blocks 5. The use of Flow Particle Image Analyzer to analyzed the wet slurry (prior to its application on the foam pattern) by measuring ceramic particle size and shape. 6. Single and multiple air gauge developed for rapid determination of pattern dimension 7. Compaction gauges were developed to measure sand density in cavities during pattern compaction 8. Distortion gauge to determine when and under what conditions pattern distortion occurs during compaction 9. Developed procedures to measure liquid absorption characteristics of liquid pattern pyrolisis 10. Developed instruments to measure gas permeability 11. X-ray radiography was developed to measure time of fill and also to inspect casting qualities and defects in LFC. Material selection is another way to improve the capability for example: * Certain materials react, (particularly in a molten state), a certain way with other materials they may encounter during the casting process. This should always be a consideration. For example liquid aluminum will react readily with iron. Iron ladles and surfaces contacting the molten aluminum can be covered with a spray-on ceramic coating to prevent this. * When selecting a specific type of manufacturing process, remember that certain materials are more applicable to different types of casting techniques than others. * The casting materials specific heat will as well as that of the mold material will be influential in controlling the thermal gradients in the system. Different materials will factor heavily on the melts  fluidity * A material high heat of fusion will take longer to solidify and may improve flow characteristics within the casting * When manufacturing a casting an alloy that freezes over a tempe rature range problems may occur due to the solid phase interfering with the liquid phase -both of which will be present within the temperature range. To help reduce this problem an alloy with a shorter solidification temperature range may be selected to manufacture the casting with. Or select a mold material with a high thermal conductivity, which could reduce the time spent in this range by increasing the cooling rate. Conclusion using the method of casting by lost foam patterns, we can obtain pieces for industry and ornamental elements / applied art, with complex layouts and different sizes, without the danger of offsetting * using the method of casting by lost foam patterns we can obtain pieces with weights between a few kilograms and tenths of tones, with wall’s width between 1 mm and 50 mm, made of different alloys: ferrous (cast iron and steel) and non ferrous (basic alloys of Al, Cu, Mg); * using the method of casting by lost foam patterns we can obtain pieces with a l ow consumption of materials and energy; * The method of casting by lost foam patterns can be used also for: structural changes and superficial alloying of the pieces; obtaining composite materials with powders insertion and the guidance of hardening by using some active powders, internal coolers or exterior coatings. The gases resulted from the thermal destruction of the polystyrene are toxic for the human being and can generate negative effects on the environment, aspect which imposes the obligation of maintaining under control both the evacuation in the working environment as well as the evacuation in the atmosphere.

Family Law Essay Example | Topics and Well Written Essays - 750 words

Family Law - Essay Example It is significant to note that marriage will always remain a viable institution because it focuses on procreation, which ensures continuity of humanity. Further, marriage assists in nurturing stronger and intelligent communities that generates a more steady society (Statsky 16). As much as technology has helped marriages, its negative effects on the institution are far reaching. For instance, social networking has led to broke many marriages because of addiction to the internet in order to keep up with the current events. Some married couples are unable to stay away from the internet and in turn give little attention to their families. Some couple through social media sites like Face book and Twitter sends flirty messages to the friends that can affect marriage in a negative manner (Statsky 32). Technology has assisted married couples to connect with old friends. Such freedom of connecting with old friends may bring suspicion to one partner in the institution because they can think his or her husband is flirting past lovers and in turn it leads to mistrust which eventually break the marriage. Since social networking encompasses things such as photo, chats, comments and information sharing, sometimes one partner who engages in social networking may make unreasonable decision in how they socialize with other people online. Unwanted behavior may be seen in the nature of sending flirty messages and sharing unsuitable videos and photos. Divorce is the legal dissolution of marriage between involved couples. Divorce cases are increasing tremendously and especially in the United States. Since the 20th century, marriage breaks have been breaking up and the peak was in the 1970s with the institution of no fault divorce. In State laws, the divorce can occur if any form of abuse directed to one partner can cause a great deal in marriage break. Abuse may take many forms including emotional

Life Histories - Essay Example Hospice workers are actually regarded as the doorway to an end-of-life healthcare system in that includes all practitioner including the nurses, doctors, counselors and chaplains. This idea is mainly observed by the society because most of the patients in hospice organization include patients that are elderly, in comatose or in crucial near-death health condition. Thus, people usually believe that hospice cares are actually health system for people who do not have any more hope for betterment. However, on the contrary to the common belief, hospice care still gives patients hope and strength to struggle for survival and alleviate their adverse health conditions. For patients who are struggling old age and only enduring their last moments in life, other principles are being applied by hospice workers towards their health care system. Thus, hospice health care becomes an important aspect in general care-giving system because of its significance and value for patients who are in serious and critical health conditions. A counselor is mainly a part of the health care system that handles psychological evaluation and gives out support at the same time while aiding the health system of the patient. For a hospice counselor, supporting the patient in psychological and emotional aspects are very much important since it is expected that the patient is already going through tumultuous depression due to his or her health condition. To better understand the concepts of the principles used and applied by the hospice counselor, the writer interviewed Sandi Sunter, a hospice counselor in the Hospice of the Florida Suncoast for already twenty years. When asked the question "How would you describe the nature of your work" he kindly replied that, "dealing with patients in hospice homes is very much emotional and requires lots of patients and understanding." Regarding the principles in hospice healthcare, the writer asked "What are the common human change principles you are using in dealing with your patients in your hospice institutions" To answer this inquiry, Sunter replied that: "Most of the patient already started to give up on their health system thus further aggravating their medical condition. Counselor must be able to give these kinds of patient further psychological and emotional assistance by comforting them through psychosocial component. Some of them provide spiritual comforting others emotional support a nd most of them must always be available for their patients. These patients commonly face fears of losing and dying thus counselor must be present for their patient to rekindle their flame of hope to continue struggling through their health care medication and treatment." In addition, for other kinds of patients who are struggling through their old age with their remaining time of their life, other approaches must be used in dealing with them. According to Sunter, most of the patients in this class have already accepted the fact that their deaths are already impending thus they only wish to enjoy their remaining moments. This will be the point where counselor should come in. They must always assure that they wish of their patients must be met and be able to give their patients supports for them to enjoy their remaining time. Hospice health care is actually a major turning point in the life of their

Hawthorne effect Essay Example for Free

Hawthorne effect Essay In today’s competitive climate lots of business owners are trying to get more from their workforce at the same time however their employees are trying to get more from their jobs. Reward and recognition programmes are one way that employers can motivate their staff into changing their key behaviors and work habits, thus benefitting the business. At the same time these schemes can also give the employee that little bit extra they are looking for from job. Motivation and reward are closely linked and there have been many credible theories written on the subject. It is widely recognised that human beings have a need to feel valued, both in their home lives and in the work place. To keep people motivated they need to be encouraged, rewarded (where appropriate) or recognised in their endeavors. One of the most valued of the motivation theories was written by Abraham Maslow from the USA back in the 1950’s. As part of his study into motivation Maslow developed a five tiered hierarchy of needs. He argued that the way to motivate individuals in the workplace and indeed in life is to satisfy the need sets one by one and in order. The first of the need sets and the most basic are the biological and physiological needs. These are survival requirements ingrained into us and evolved with mankind for tens of thousands of years, things such as food, shelter, warmth etc. In Maslow’s model it’s these needs that need to be satisfied before anything else, for example there is little point offering status as a motivator, when the individual has not yet satisfied basic requirements such as achieving a livable wage in order to eat, secure shelter etc. Reward Systems Peformance at Mark-it-Down Co Ltd is not what it should be and it has been decided between senior mangement and the Human Resources department that the introduction of a reward scheme is whats required to motivate the workforce and improve performance overall. The team in charge of deciding on the reward system to implement have come up up with the following suggestions: Variable Pay/Bonus Scheme A scheme of variable pay is one possible solution for the supermarket. In this scheme a portion of the employee’s pay would be considered at risk. This portion of the wage will be rewarded according to the performance of the company as a whole, on the basis of personal acheivement or based on the results of a department or team (this would probably be the most effective for this type of commercial business) Targets will be set at the beginning of a specified period (per annum is the common period) at the end of this period depending on the how well the targets have been met, a percentage or full quantity of the â€Å"at risk† part of their pay will be paid to the individual. This payment could take a few different forms, possibly a cash bonus, a quantity of stock or shares in the business. Whilst monetary reward has been proven to be effective and can encourage hard work amongst a team or individually, it has the disadvantage of impacting on profit made by the supermarket, for example if the grocery team meet their target for keeping the produce displays replenished to a defined level, then the whole grocery team will have earnt the bonus which must be paid from the profits. You also may have a situation where part of the workforce become demotivated, if their team or they personally have missed out on a bonus. Bonus and pay based rewards are considered differently depending on which motivation theory you study. For example in Maslows hierachy of needs, financial remuneration is only mentioned within the first tier of the hierachy which covers the most basic and obvious survival needs (physiological needs) Money was not considered by Maslow be a long term motivator. Frederick Herzberg considered financial reward to be amongst his â€Å"hygiene factors† that is that money in itself is not a motivator but actually will only act as a â€Å"dissatisfier† if the individual feels that their financial expectations and requirements of the role are not being met. In contrast to Maslow and Herzberg, John Stacey Adams might have argued that bonus schemes and pay related rewards can indeed be effective motivators. If the individual percieves that they are gettting a fair input to output balance in comparison to their peers eg, works hard (input) for a pay bonus (output) However that motivation through financial reward might not last. If the individual learns that a colleague or peer is benefiting from a better input to output ratio (eg doesn’t work as hard, but gets paid more) then the individual can quickly become dissatisfied. Promotion The introduction of a promotion programme could be a viable option. If the employee’s are aware that there is a realistic opportunity for them to progress within Mark It Down Co then they will likely feel motivated towards improving their standard of work in the hope that they will be one of the employee’s chosen for promotion. Maslow’s heierachy of needs supports promotion as a motivator, however depending on the person promotion/status as a form of motivation might be quite high up on the tiers and as such it would only work if the tiers below have already been satisfied. There could be several downsides to this however; often with promotion comes a rise in salary for the individual, which will of course impact on any profit made by the supermarket. There might also be a risk of a culture developing within the company whereby individuals take the attitude that they are â€Å"out for themselves† Employee of the Month One of the suggested recognition programmes is an employee of the month scheme. The idea is that all employee’s and managers are provided with a brief form to be used to nominate an employee that they believe deserves recognition (they should also explain the reasons behind there nomination) Due to the nominations for employee of the month being business wide not only is the playing field for recognition level, but there is the scope for recognising excellance in all of the different area’s of the organisation. This reward system could be as low or high cost as Mark it Down Co directors see fit. There is support for this type of recognition reward in Elton Mayo’s Hawthorne Effect theory. Following his studies of workplace behaviour at the Hawthorne Plant Chicago in the late 1920’s and early 1930’s Mayo deduced that emotional factors acted as far better motivators than economical ones, as such a reward scheme of this nature could be very effective indeed, not to mention low cost. On the downside employee of the mon th schemes can have a tendancy to be considered a little cheesy and may require a little effort on the part of the programme managers in order to keep all of the staff motivated to particiate by completing the nomination slips. Pass on Praise Something as simple as passing on positive comments you have heard about an employee direct to the individual can have an extremely motivational effect. Again the hawthorne effect supports this belief. The praise could passed on by way of email, copying in managers or even with a visit to a senior managers office in order to receive thanks directly. The main advantage of this idea is that it costs nothing and is extremely easy to implement, however it may not be enough on its own, I would suggest that this tactic be used in conjunction with one of the other employee recognition schemes. All of the afore mentioned reward options have the potential to be effective, however the success of the chosen scheme could have a lot to do with the indviduals in nbeed of motivation. For instance in McGregors theory, the two employee types, X and Y differ greatly. What might motivate a Y employee (someone that is naturally happy to take on repsponsibilty and excepts work as part of life) might have the opposite effect on an employee of the X variety (someone that’s avoids repsonsibility and needs to be heavily supervised. The type of employee’s to be motivated should be considered before a motivation and reward scheme is decided upon. Monitoring Performance There are various ways to monitor the performance of your workforce. In the supermarket setting of Mark it Down Co, these could be; Physical: the number of sales made, the number of employee’s served, punctuality or attendance. There can be no disputing these types of performance indicators they are unambiguous and offer a realistic insight into the performance of a team or individual. Qualiative: these indicators are based on opinions and judgements (the view of a supervisor or the such like). These indicators are just as important as physical ones but managers should be careful to ensure that any measures of performance are considered fair by both the employees and employers. Goals and Targets Performance measurement can also be linked to the companies appraisal system, that is performance can be measured by assessing progress made on targets and goals agreed at the previous review. Appraisals are valuable in this respect. In order to effectively monitor performance in this way it is important to ensure that your employees are aware of the difference between target and goal. Goals: These are long term ambitions that should relate to the individual aims for progressing within the company. Targets: These are the steps taken in order to achieve the goal. There is an acronym that can act as a guide for the criteria that any targets should adhere to. They should be Specific, Measurable, Achievable, Realistic and Time bound. There is little point setting targets outside of these parameters. Monitoring progress towards identified goals and objectives as a way of determining who deserves reward does have its pros and cons though. On the one hand it can be considered an easily measurable method of monitoring performance, but on the other (particularly when the goals and targets have been set for a team or group) it could be argued that the fact that a company/team or individual is achieving its set goals and targets is not a true indication of who has made the most effort towards making that happen and as such is not an effective method for identifying who should qualify for reward. This is an important thing to consider when applying motivation and reward schemes, as an incorrect or ill managed monitoring technique could be costly to a business. For example a company will not want to be handing out cash bonuses to a whole team for reaching a set goal if it transpires that 3 out of 5 team members have made no improvement to their work output and had nothing to do with the team’s progress or achievement! When considering target setting as a way of monitoring progress and establishing where reward, praise or recognition should be given, serious thought should be given to how the company plans on pinpointing exactly who has been responsible for progress, both positive and negative. Benchmarking Another way to monitor company performance is to measure its successes and failures against those of other businesses in the same market. For example Mark it Down Co could measure its sales figures against one of its competitors, Lidl for instance. This method is known as bench marking and it’s all about taking the best practices of the highest achieving businesses in the same market and applying them back in the business in question. Job Evaluation Its has been brought to management attention that one of the employee’s at Mark it Down Co believes that he is receiving less salary for the same work as one of his peers. The following two methods can be used to evaluate the jobs of the individuals in question in order to assess whether theses concerns are justified or not. Job Ranking Job ranking is one of the simplest methods of job evaluation. Its considers the job as a whole and ranks it against another whole job within the organisation. This is usually carried out by the raters comparing the jobs using their general knowledge of the roles themselves. The jobs are ranked in order of the difficulty of the job itself or the importance of the role to the company. The procedure is followed for each department and then a comparison of jobs at all levels is made and jobs are given grade levels which define salary groups. The job ranking method is easily understood by all employees and simple to administer, however it does have its disadvantages, this technique is not really suitable for large organisations with complex structures where its is much harder to gain familiarity with all of the job roles. With this in mind it is probably not the solution that should be used at Mark it Down Co Ltd. Point Factor Method The point factor method establishes job values by assigning points to each area within a group of defined factors, below are some examples but there any many different factors that could be defined further and given points in order to be used for job evaluation; Skill: Within this group there might be points available for, experience or training. Effort: The points available for effort might be divided between mental and physical effort. In this method each job is rated using the defined points system. The points are totaled to form the final score for that particular role. From there jobs are grouped into salary grades (jobs with similar points ratings would be placed together in the same salary grade) This method can be tailored to meet the needs of specific companies and is suitable for use within larger organisations where there are a large number of jobs to evaluate. It’s an easy model to work with once it’s in place but can be very expensive and time consuming to develop in the first instance. In my opinion the point factor method would be a the better job evaluation model to use for Mark it Down Co. Job ranking is just too simplistic to cope with the amount of individuals roles at this organisation. The factors I think should be used to develop the point system are as follows; Skill – Experience, Training, Ability, Education Responsibilities – Monetary, Supervisory, Reporting Effort – Mental, Physical Environment – Job Location, Hazard’s In order to establish if the employee in question has a case for querying the wage he is on in comparison to his colleague. His overall score for the above factors should be calculated in order to establish his pay bracket. If the pay grade is the same as that of his colleague then his concerns are justified and his wage should be brought into line. If it is not and he is in a lower wage group then there is no case for a wage increase. Equally if the individuals wage bracket is determined to be higher than that of his colleagues then his wage should be adjusted to reflect as much.

An Ethical Dilemma Essay -- Animal Rights

According to Viren Swami, a professor at the University of Westminster, â€Å"animal testing, or animal research, refers to the use of animals in experiments within academic, research, or commercial establishments† (Christopher, 269). Sounds simple enough, but Swami does not mention how this testing affects the animals or why this is such a controversial issue among the public. M.J. Prescott, from the National Center for the Replacement, Refinement and Reduction of Animal Research, makes a very good point when he says that: Many people, including from within the scientific community, consider that the use of NHPs [nonhuman primates] in research is a matter of particular ethical concern because certain features NHPs share with humans, such as their highly developed nervous systems, cognitive complexity and intense sociality, have implications for the level or nature of suffering they might experience during experiments and are therefore morally relevant. (14) The close relationship between NHPs and humans is one of the reasons why so many people care about the use of NHPs in medical research. Based off of Darwin’s Theory of Evolution, many people believe that humans evolved from primates which would make them the next-to-kin of human beings. This close relationship makes NHPs the best option to get the most accurate results from a medical experiment, but it also makes them the animal that most humans sympathize with. Using any kind of animal for medical research is wrong because it is wrong to inflict pain or cause premature death to an animal, there has been a significant increase in the number of NHPs in research, and there is no way for animals to give their informed consent to be used in medical research.

Group Counselling Essay

In an effective functioning group, the members are striving to carry what they are learning in a session into their everyday lives. They do this by formulating plans to practice between sessions, by making a commitment to do homework assignments and by practicing a variety of new behaviors outside of the group. Perhaps the two most important phases of a group are its beginning and its end. The beginning because that is where the tone of the group is set; the end because that is where learning is consolidated and action plans are typically formulated. (pg 164) There are some tasks to be carried out during the closing session! (ending a group) * Members are encouraged to complete any ‘unfinished businesses’ they may have with other group members or the leader. * Members are taught how to carry with them what they’ve learned and esp. how to talk to significant people in their lives. * Members are assisted in making specific plans for change and in taking concrete steps to put the lessons learnt into effect in their daily lives. * Leaders help members discover ways of creating their own support systems after they leave the group. * Specific plans for follow-up and evaluation are made. NB. The more behavioral approaches like; transactional analysis, behavioral group therapy, RE behavior therapy and reality therapy – place primary emphasis on the above mentioned tasks. This owing to the belief that, members ought to consolidate their learning, practice homework assignments and develop a specific action plan, if they expect to make significant changes in their lives. Body: Time is limited in a group counseling session. The leader therefore, constantly remains aware of that and teaches participants how to best use the time available to them. Leaders also need to train members on how to pace themselves so that they do not wait until the end of the session to introduce work that cannot be addressed in the short time remaining. Good Practice to Carry Out When Ending a Session: I. Asking Members to Sum up! The leader may allow about 10min at the end of a session for members to summarize what the session has meant to them individually. Some questions that may be asked to help members consolidate their learning include; a) Could you briefly summarize what the session has meant for you? b) What steps towards your goal are you willing to take between now and our next session to make changes in your life? c) Was there anything unfinished for you today that you would like to continue in our next meeting? d) What was the most important thing that you experienced during this meeting? e) What touched you most in other people’s work today?  f) What did you learn about yourself? g) Did you get what you wanted from this session? (what in specific?) Questions like these assist members in identifying specific behaviors they must want to change, both in the group and in daily life. They also reinforce their commitment to make changes. II. Dealing with Unfinished Work! In the case that some work in a session isn’t going to be finished before the group ends, the leader can help bring a sense of closure simply by acknowledging those incomplete explorations or feelings that are left unspoken. This he can do by simply asking the client to differ the discussion until the next session. For example, â€Å"Since we’re running out of time today, would you be willing to reflect on it a bit between now and the next meeting, maybe do some writing, and bring it up again then!† #Activity during this time# Psychodrama: There is a procedure for closing a group session in Psychodrama that increases the chances that members will be able to identify and deal with unfinished business. Psychodrama emphasizes allowing enough time for the sharing and discussion phase for each session. #Sharing which comes first, consists of nonjudgmental statements about oneself. Then after the personal sharing, time is allotted for a discussion of the group process. Members who have engaged in a role-playing enactment are invited to share their reactions to those roles. Others are asked to tell members who participated in a psychodrama enactment how they were personally affected by the work and what they learned from it. III. Arrange Homework Assignments!  Having members announce Homework assignments or some means of carrying further the work they have done in a session, and then report on the same, at the beginning of the next session is a closing technique – it also links the ending session to the next. Homework can be deviced by members themselves or the leader. Keeping in line with behavioral approach, it is important for leaders to teach members that; â€Å"the crucial change is the one that takes place in the real world.† And this is where homework comes in handy. The main point is that insight alone rarely results in behavioral change. [‘Insight needs to be translated into action for change to occur’ – premise of the Adlerian Perspective.]pg. 168. IV. Making Your Own Comments and Assesments!  Leaders may form a practice of giving their reactions, a group process commentary or a summary of the meeting towards the end of the session. Leaders might comment on; * The cohesion of the group  * The degree to which members freely brought up topics for work * The willingness to take risks and talk about unsafe topics * The degree to which they interacted with one another (as opposed to speaking only directly to and through the leader) * Their willingness to discuss difficult concerns Leaders might use write up notes about each session during the week and use those comments at the beginning of the next session as a catalyst for linking the sessions! Another way to close session is to set apart the last 5min for members to fill out brief rating/assessment sheets. The ratings can be tallied in a few minutes and the results presented at the beginning of the next session. A rating scale of 1-5 can be used. Questions that can be asked include; a) To what degree were you involved in this session? b) To what degree were you willing to take risks in the group? c) To what degree did you trust other members in the group? d) To what degree has today’s session stimulated you to think about your problems, your life situation, or possible decisions you might want to make? e) To what degree were you willing to share what you were feeling and thinking in the session today? f) To what extent are you willing to actively practice some new behavior this week? g) To what degree did you prepare yourself or think about this session before you came today? h) To what degree are you willing to non-defensively take the feedback you receive and consider it carefully? i) To what degree did you see the group as productive today?

Kant VS Mill

Immanuel Kant was born in April 1724 to a craftsman named Johann George Kant and Anna Regina Porter (Bennagen, 2000). He was trained more in Latin and Religion subjects as compared with science and mathematics consequently forming his concepts and ideas with regards to moral philosophy technically referred to as ‘deontology’ which actually reiterates that an act should only be carried out based on the an individuals’ responsibilities (Bennagen, 2000).John Stuart MillJohn Stuart Mill was born in May 1906 to Harriet Barrow and a well known philosopher, James Mill (Bennagen, 2000). Being exposed to Greek when he was only three years old, Latin when he was eight, he was extremely brilliant, so intelligent that he acquired Greek Literature, Philosophy, Chemistry, Botany, Psychology and law before he turned eighteen years old (Bennagen, 2000).Furthermore, he is accountable for systematically putting together the utilitarian thoughts/concepts/ideas of his father and his father’s friend Jeremy Bentham (Bennagen, 2000). This is where Jeremy Bentham argues and reiterates that actions are correct only if they are inclined to bring into being the utmost happiness for the greatest number of people (Bennagen, 2000). This is simply because advocates of utilitarianism believe that happiness is the main criteria for doing something right or wrong, meaning if something is done and pleasure resulted from it then it is right, however, if pain was brought about from it then surely, it is wrong (Bennagen, 2000).Major Similarities in their Ethical SystemImmanuel Kant and John Stuart Mill’ ethical systems have similarities and these are the following:In act utilitarianism, laws are not taken into consideration as long as the act is said to have brought about happiness to most individuals then it is right (Bennagen, 2000). The same is true with deontology wherein duty is the basis for a right act which means that even if it means breaking the law just as long as the responsibility is fulfilled then the act is definitely right (Bennagen, 2000).  In addition, both cannot always be utilized as a guide to morals (Bennagen, 2000). There are several cases where a decision made based on utilitarianism or deontology fails (Bennagen, 2000).Major Differences in their Ethical SystemThere are differences between the ethical systems of Immanuel Kant and John Stuart Mill and some of these are the following:In terms of goal, Immanuel Kant’s deontological theory’s goal is to fulfill a certain duty, whereas, John Stuart Mill’s utilitarianism’s goal is to achieve happiness (Bennagen, 2000). This is clearly evident in the definition of the deontological theory which says that individuals ought to stick to their responsibilities in evaluating a moral quandary (Bennagen, 2000). Same is true with the technical definition of utilitarianism where it states that, in an assessment of an ethical issue, the alternative that wil l result in the greatest happiness to the most number of people is the option that is ethically right (Bennagen, 2000).Also, rule utilitarianism considers the law and fairness in finally making an act which is said to be right (Bennagen, 2000). Here, an individual who is about to make an act seriously thinks about making the most number of individuals experience pleasure through fair and just means (Bennagen, 2000). Furthermore, it gives importance to justice, as well as, beneficence (Bennagen, 2000). By justice here, we mean, that everyone involved in the situation are treated fairly, on the other hand, by beneficence, we mean, doing what is good, in opposition to what is evil (Bennagen, 2000). The aforementioned defies deontology in such a way that it does not involve justice and beneficence in it, rather it only focuses on fulfilling the ‘duty’, whether or not it is fair or just to everybody involved (Bennagen, 2000).Major Criticisms for Kant’s TheoryThere are also criticisms for Kant’s Theory and some of these are the following:First of all, since deontology is all about sticking to responsibilities, its rationale or logic is being questioned for it (Bennagen, 2000). For instance, how will individual duties would be defined (Bennagen, 2000)? If for example, if personally I consider my family as my first priority every time and it so happened that I am being called by my supervisor for an urgent or emergency meeting, would it be considered not doing my duty if I go to this emergency meeting that my supervisor has ordered (Bennagen, 2000). Another example is the fact that, citizens have to maintain a certain driving speed, however, an individual is running late for a qualifying exam in medicine, which is a make or break exam for him, would it be considered as not doing his duty if he went a little speedy just to make it to his exam, which is a personal duty for him in the first place. Very clearly, through the aforementioned exampl es, there are no limits or boundaries to this so called duty making it critical, even questionable, as an ethical theory (Bennagen, 2000).Secondly, obviously it is not extremely useful or helpful in making decisions since it is not applicable in all situations, as seen in the examples above (Bennagen, 2000).Last but not least, it is also being criticized because of its self-centeredness simply because it does not really consider the well-being of others (Bennagen, 2000). Going back to the aforementioned examples, it shows that deontology tends to take a certain side wherein the other side not chosen is left unprotected in terms of its welfare (Bennagen, 2000).Major Criticisms for Mills’ TheoryThe criticisms for utilitarianism include the following:First of all, in making a decision using the utilitarianism, it does not always achieve its goal of the experience of the utmost number of people of the greatest pleasure (Bennagen, 2000). If the head of the family decide to unleash his dog in his yard at night to make sure that no one will jump over his fence and to make sure untoward incidences in his home are avoided which may consequently hurt his family, but unfortunately the dog got out of his yard and went over the neighbor’s yard and destroyed the flowers in the garden (Bennagen, 2000)? This means that instead of his family being happy being they were well guarded, other people were terribly disappointed, disturbed, and definitely did not experience happiness as should be the outcome of utilizing utilitarianism as a technique in making ethical decisions (Bennagen, 2000).Secondly, many people criticize utilitarianism for its inadequacy of common sense (Bennagen, 2000). For example, would you give up the one you really love just because your best friend loves him too and for the reason that your family does not like him for you (Bennagen, 2000)? Your best friend will turn out happy and so will your family which complies with the technical definiti on of utilitarianism involving utmost happiness experienced by the greatest number of individuals (Bennagen, 2000). The questions however are ‘what about you’, ‘where is the common sense in that’, and ‘is selflessness common sense’ (Bennagen, 2000)?Thirdly, happiness is undefined here in utilitarianism (Bennagen, 2000). For example, a customer service representative at a certain company has been reported to be sleeping on the job (Bennagen, 2000). Utilizing utilitarianism, the act has been carried out: 1) to correct the mistake of the customer service representative; 2) to serve better more consumers; and 3) to improve the company’s services and be appreciated by more clients (Bennagen, 2000). This may result in happiness for the consumers and the management; however typically, this will not bring in pleasure to the customer service representative being complained about (Bennagen, 2006). This only proves that an act may not always bring in happiness through the use of utilitarianism in carrying out an act (Bennagen, 2000).Last but not least, utilitarianism is being questioned because it violates human rights (Bennagen, 2000). For example, if a Bill is submitted by a minority group leader to be passed as a Law, and will not qualify as a Law simply because majority did not vote for it, then this may jeopardize the rights and happiness of the so called minority groups (Bennagen, 2000). This then may also be justified as an act which is right since happiness is being experienced by the most number of individuals though several people are suffering as well (Bennagen, 2000).ReferenceBennagen, P.
