The Affordable Health Care Act Essay Example for Free

The Affordable Health Care Act Essay The Affordable Health Care Act Introduction            This paper puts into a critical and analytical focus the diversity and benefits of the Obama care. It seeks to answer fundamental questions about the advantages and necessity for the act. The affordable healthcare act mirrored with both merits and demerits deciphers its complex nature. The bill signed into law on twenty-third of March 2010 to make critical reforms in the health sector. The health care provision has attracted much of sharp reactions especially from the wealthy society protesting hefty taxes.            The goal of the Obama care is to give access to all Americans quality and affordable health care. This plan focuses on the reduction of growth in health care spending. A significant percentage of the benefits will accrue to the low and middle-income families and citizens. It achieves this through consumer protection, subsidies, taxes, regulation and insurance exchanges. Fundamentally, the Obama care provision is not a replacement to Medicare, private insurance or Medicaid (Wilensky, 2012). The primary focus of the health care facility is regulation of health insurance and practices that affect the sector.            Nevertheless, the contrasting fact is that the Obama care posse’s a lot more significant bunch of questions. Is there a need for health insurance for the richest country in the world? Is it the best the government can offer for the needs of Americans? However, the complexity of the answer to these questions is not a fragment of a sentence. Therefore, before the induction of such a debate some ground rules are principal (Mulligan, 2014). First is an agreement of the fact that the government cannot have an individual approach to protecting the desires of every citizen. Secondly is that the health cover such as the Obama care primary target, is the vulnerable middle class and poor society.            The wealthy society though consistently and constantly complaining about the plan also will benefit from the program. An optimistic look at the system ensures the acknowledgement of certain advantages. The policy prevents against gender-based discrimination, unjustifiably high insurance rates. Significant benefits worth discussion with regard to the annual limits imposed by insurance firms, as well as the right to rapid appeal of the insurance company decisions. This benefits cut across the divide from the middle class to the wealthiest in the society.            The health care industry has seen to the growth in wealth and stature of many fraudulent characters. This includes one who prescribes very expensive drugs even though the cheaper ones can work just for profits (Tate, 2012). The doctor who insistent on surgery whiles a consistent observation of the patient will ensure recovery. A doctor is busy ensuring the readmission of patients who he can monitor at home. Some companies sell machinery at extraordinary hiked prices just for profits. These cases among others ascertain an advantage of the rich over the employed middle class and the poor.            This trend in the health sector increases the cost of living since most Americans are profoundly concerned about their health. A critical look at the developed world countries alienates the United States in health insurance policies. Most of the developed world has a medical insurance policy. In contrast, one of the most riches of them argues about, politicizing the fact that it is a necessity. Fact remains that the multinational companies and big business have created their wealth through the citizens. Most of them are taking advantage of the smaller businesses or the society’s lack of knowledge. Through the articulation of the health care, the businesses get to give back to the society. This may deem improper by many who are in this class, but to some extent, it is a kind gesture.            However, the consideration of certain healthcare statistics is important. A significant 30.1 million people purchase private insurance. Many of them have had their plans cancelled by the company since it does meet the ten essential health thresholds. The cost of replacement of such is very high due to services such as maternity that they may not need. A significant 4 million people could lose their company sponsored health care plan (Wilensky, 2012). This is because many companies will prefer paying the fines and allow their employees to buy their plans. Conclusion            There is a genuine sense in negative approaches to affordable health care. Nevertheless, framework solutions created specifically will solve these issues. A trivial approach to the impediments may have worse negative repercussion to the minority in the society. This will result to the upwelling of negative economic growth. The return of the United States to the set-up of insurance policies existent before will not solve problems in the health sector. Rather a degradation and increase in fraud in the health care section will form complete dominance. The health care program will be successful if approached with a positive mindset and inclusion of all individuals with equality. References Mulligan, C. B. (2014, September 8).

Advantages of supply chain management Essay Example for Free

Advantages of supply chain management Essay One is cost advantage. Companies that have implemented supply chain management have a 45% supply chain cost advantage over their competitors. [1] Price of raw materials and end product are optimized due to collaboration between two parties. The sharing of vital information in the early stage of development, and the effective communication of methods and requirements allows parties within the supply chain to effectively benefit each other in terms of cost. Another is faster time to market. Companies met their promised delivery dates 17% faster than their competition. [2] Through early information and forecast, suppliers can also efficiently design their production and implementation process through collaboration. This allows supplier to reduce the lead time to produce their products within the supply chain. Disadvantages of supply chain management over traditional competitive procurement processes. First is the difficulty of maintaining supply chain relationship. Supply chain relationships are probably the most fragile and the most susceptible to breaking down. [3] This is because a poor relationship at any part of the supply chain can cause major problems to the entire supply chain. In today’s global market, the customers have the power over the suppliers. Everyone else in the supply chain must quickly satisfy the demands or else face the possibility of loosing them. Another disadvantage is the need to share vital information for collaboration purposes which leaves a company vulnerable to illegal copying of ideas or methods. Although these can be safeguarded by proper agreement between parties, but the forces of market competition may compel violations of agreement intentionally or unintentionally.   If supply chain management is actually a superior way of managing procurement and production, how (if at all) does that modify any of the economic `big ideas` we examined in Module 1?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Supply Chain Management plays a major role in the concept of supply and demand. With parties closely related through collaboration, the identification of demand which is needed by the suppliers to support the collaborative company is easy, allowing suppliers to maximize profit given the level of demand. On the side of the collaborative company, the control of supply of raw materials is easy, which again would allow them to optimize profit. References: Ferguson, B. (2000).

Studying The Erp System Problems

Studying The Erp System Problems Hindustan Unilever Limited is Indias largest fast moving consumer goods company. The common HUL brands include Kwality Walls icecream, Knorr soups and meal makers,Lifebuoy,Lux,Pears,Breeze,Sunsilk and Dove shampoos, Vim dishwash, Lakme beauty products etc. Problems faced by the company before ERP implementation: There was an arrival of modern trade in India. Its business infrastructure and various legacy systems were unable to meet the requirement for transactions and process capabilities of the modern trade.A legacy system means the computer has been in operation for a longer time and so its functions. Hindustan Unilever was not able to streamline its business operation. There was a need of much more smooth flow of information. HUL was facing a challenge of ensuring the optimization of business to have solutions to changing market needs.Company was also facing the challenge of reducing its stock replenishment cycle. Need for ERP implementation: To optimize business process and simplify IT management. 2. Consolidation of process is necessary.This must be done internally as well as across the value chain. 3. For the preservation of investment related to legacy inventory and cash-to-order management system.Cash to order management system is for the business partners. 4. Integrate with business partners IT infrastructure quickly and seamlessly. 5. To improve information sharing with partners even if they are not using SAPs solution. 6 .Increasing Supply Chain efficiency through process centric collaboration across the enterprise-internally and externally. 7. Enhancing the value of legacy system. 8. ERP system was also needed to ensure the distribution of goods at the right time at right places In this period of modern trade one needs to deliver a service level that is higher than what the industry provides right now and their supply chain has to be such that it is superior to its competitors. Their older version of ERP system was such that it was not able to meet these needs.Hence they were in search of a system which would help in catering like meeting future transactions of modern trade. HUL also realized that good communication skills and tight communication links was necessary for the optimization of its business and achieving higher efficiency of their supply chain . However, ensuring good connectivity between HULs IT system with its distributors was not an easy. Earlier the company was using an e-business system which was developed inhouse. This was to manage the processes of replenishment and order fulfilment. This was done by exchanging inventory and sales data between itself and their distributors. Synchronization was also necessary. But because their customers had multiple, different systems of their own, integrating their system with those customers to and ensuring smooth data exchange was a challenging task for them . Furthermore, the module of the E-Business system was customized..So as their business experienced growth, there were problems managing themselves with changing business needs. HUL has developed a standard distributor management system in a distributed general trade environment. If one wants the extended supply chain to be covered, the operations of the distributor needs to be integrated tightly with its internal Enterprise resource planning solutions .The system is functioning quite good, Hindustan Unilever Limited wants to its investment t be preserved in this area. Therefore the new ERP application must be able to integrate itself with this back-office application, so that the company can continue to use its borrowed money well or leverage and maximise this into the future. ERP IMPLEMENTATION It was in 2004 when HUL decided to renovate its IT system with SAP. By utilizing SAP as their provider of standard IT solutions , utilizing its enterprise which is full of different features, solutions and it fine experience in the consumer goods industry,thy will be able to execute their global transformation strategy. This strategy was aimed at streamlining and standardising the business processes across all its operations including global operations.It was to accelerate their transformation of business and simplify their IT department. The deal for HUL was SAP NetWeaver Process Integration (SAP NetWeaver PI) which enabled process-centric collaboration internally and across HULs extended value chain. SAP NetWeaver PI facilitated communication and an transfer of info between different applications together or multiple applications irrespective of whether it is an SAP or non-SAP solution. Why SAP implementation? It supported wide range of integrated Advanced Business Application Programmiing(ABAP) and SAP applications which are based on Java used throughout Hindustan Unilever Provided opportunity to drive new enhanced change and transport system functionality of SAP Solution Manager Phase 1 of HULs SAP implementation It was in Sept 2007. It was marked with the end of its legacy ERP and its e-business systems. The solutions which were deployed included SAP ERP Central Component (SAP ECC), SAP NetWeaver PI, SAP NetWeaver Business Intelligence (SAP NetWeaver BI), SAP NetWeaverComposition Environment (SAP NetWeaver CE), SAP NetWeaver Portal, SAP Solution Manager and SAP Supply Chain Management (SAP SCM). The most important thing for them is that by implementing SAP NetWeaver platform, they are fit to consolidate and exchange data which is critical for business across their internal processes and also externally with their partners,their various suppliers and different partners too. For eg, HUL is now able to retain or hold back its investment in Central Unify and Unify which is also their aim.It is possible due to SAP NetWeaver PI. It is due to this software that integration of the the legacy inventory and order-to-cash management system is now possible with the rest of the SAP-based system. SAP NetWeaver Portal is another SAP NetWeaver component that HUL is most impressed with , which is right now used for customer collaboration. Integration of HULs IT system with its distributors IT systems is now possible by replacing its e-business system with this portal. This therefore results in the replenishment and order fulfilment process. With SAP NetWeaver PI, we have finally streamlining, advancement and integration of their process capability hs finally become possible because of their SAP NetWeaver PI. This also has resulted in the enhancement of HULs ability in meeting modern trades demand. Phase 2 of SAP implementation: Includes implementation of SAP Customer Relationship Management, SAP Transportation Planning and Vehicle Scheduling, SAP Advanced Planning Optimisation Production Planning and Detailed Scheduling. Manufacturing/Production software: The Distribution Module of MFG / PRO offers users Functionality in the areas of Purchase, Inventory, Sales and Distribution, Configured Products and SCM are offered in the Distribution Module of MFG/PRO.

Fluctuation in manpower is low. 5. Customer satis and nightfaction level is at its peak as the helpdesk is open for the whole day and night. 6. Economical Benefits are considerable. MFG-PRO Process : Step-1: The first step is getting the orderà ¢Ã¢â€š ¬Ã‚ ¦. a. One gets the order online. b. All orders are consolidated from website to excel sheet c. The excel sheet is then send to the Operations Department d. Material Requirement Planning is then done in MFG/PRO Calculation how much inventory is in the stock how much inventory is required will be done by MFG/PRO Step -2 : Step 2 includes management of raw materials Supplier is informed about the quantity of raw materials to be supplied ordering is done here) Raw material is then received from supplier. Goods Receipt Report(GRR) is then prepared by MFG/PRO. Step 3 Qulity Control is done here Material is then transferred to the Quality Control Department: Different stages are (1) Q.C. Pending (2) Q.C. Accepted (3) Q.C. Rejected The one which is accepted is transferred to warehouse. One which is rejected is sent back to suppliers.MFG/PRO does the accounting entry of it. Step 4 : Also called production stage Raw Material is Transferred to Production unit. MFG/PRO prepares Production Report is prepared by MFG/PRO Daily Production is recorded Step 5 : The process reaches the dispatch stage Guidiance how much to dispatch will be done by MFG/PRO. The Remaining is stored in warehouse. 3. A mail to the customer will be sent by MFG/PRO. Step 6 : Payment to the supplier is done here : A Message to the central department is sent by MFG/PRO, after 1 week of receipt of material payment will be done centrally. The entry of it will be done by MFG/PRO when the payment is done.. Payment from Customer: After the 3 weeks of dispatch of the finished goods to customer, central department will be messaged by MFG/PRO to ask for payment from the customer. Entry will be automatically done by MFG/PRO when the customer does payment. Waste checking Manual method is followed for capturing the waste. MFG/PRO will compare Material reduced Finished Stock Increased and theri difference would be calculated as waste. Profit Calculation Profit Statement will be prepared by MFG/PRO every month. There will be comparisons of previous profit statements.

Hindustan Unilever uses it to manage front end operations,backend operations,various business relationships,analysis and operational CRM. The growing information needs have to be met and the business practices have to be standardised.For HUL implemented Secondary Sales Force Automation (SSFA) Application across its redistribution stockists. Computer Manufacturing Company (CMC) has already implemented the Dealership Management Application Software for HUL distributors as part of earlier engagement. Connection between the redistribution stockists with the central database takes place through Internet-based network for online interaction on orders, information sharing,dispatches and monitoring. Companys Existing Scenario : Their existing environment consists of SAP ERP application , SAP NetWeaver ® Exchange Infrastructure Component , SAP NetWeaver Business Intelligence Component , SAP NetWeaver Portal component, SAP Supplier Relationship Management Application , SAP Customer Relationship Management Application. The company now enjoys 70% speedier transports for non-ABAP (Advanced Business Application Programming) software Greater degree of automation and accuracy Elimination of disruptions and mistakes almost completely in ABAP and non-ABAP change transports Reduction in costs through reduced dependency on specialists which possess specialist skills Third-Party Integration à ¢Ã¢â€š ¬Ã‚ ¢ Database: Oracle à ¢Ã¢â€š ¬Ã‚ ¢ Hardware: IBM HUL Before ERP There were 1,000 suppliers and 7,000 stockiest in over one million retail outlets.HUL has 100 factories, 121 warehouse depots, 13 sale branches and 93 third-party manufacturing sites. It has 23 central offices, two research centers . CF agents used to Planning of distribution was done by CF agents based on the demand which was raised by stockists. 60-90 days credit for the goods were given to C F agets and stockists. In 1995, 44% was the HULs net current assets as a percentage of capital employed, and inventory was 20% of divisional turnover for detergent and for personal products it was 24% divisional turnover. HUL after ERP HLL previously had a stock replenishment cycle time of two weeks after ERP implementation, it came down by three and half days, which translates into substantial savings in inventory costs. After ERP current assets as a percentage of capital employed was down to 8 percent, and inventory in key divisions was down to 5-6% of turnover. In the case of detergent,the stock level decreased to less than 3 weeks of sale from 6 weeks of sale. Finish goods stock level at distribution decreased from three weeks to one week. The stockists of HUL who were habituated to get 60-90 days of credit from HUL are now offered a special discount if the payment is in advance. As a result, orders are placed by stockists only for those stocks that can be replenished quickly. The channel inventory has drastically reduced in the entire network.

Brave New World - Fears Of The Future :: essays research papers

Art is like a fractured mirror that reflects the society in which it was created. This reflection is a mosaic of images constructed by the artist’s own perceptions which in turn are determined by the values and attitudes, especially the fears and insecurities in his or her own contemporary society. The responder also has to acknowledge his or her own door of perception, as this would affect their interpretation of the art. This is especially evident in texts like Brave New World which are designed specifically as probes into the aspects of society that the writer desires to explore. Aldous Huxley wrote Brave New World during the late ‘20s and early ‘30s; in the middle of the Great Depression and at the eve of the Second World War. World War One was still fresh in everyone’s memories and so was the Bolshevik revolution of Russia, which threatened to spread throughout Europe and the world. On the other side of the Atlantic the †New World† was unde rgoing a revitalisation of industry with Henry Ford and other leading capitalists implementing the concept of mass production and attempting to create the ideal consumer society. There was also a form of cultural renaissance in the central European countries where the avaunt-garde was embraced rigorously in art and architecture. And in science, especially in the biological field, great breakthroughs, the likes of which the world hadn’t witnessed since the days of Newton were being accomplished. In short it was a period of great social change and instability. Such instability eventually leads to fears and insecurities, most of which tend revolve around the future of society and the future of the individual. For the rich upper class the primary fear was Bolshevism. They feared it so much so that Fascists and Nazis were tolerated, even encouraged, all for the purpose of crushing Bolshevism. Although the World State from Brave New World does not resemble Lenin’s Bolshevik state, it does however have strong parallelisms with Mussolini’s fascist Italy and shares an uncanny resemblance to the future Germany under Hitler. Even more profoundly and more importantly it’s resemblance of Stalin’s totalitarian Russia is undeniable. From the characteristics of the World State in his novel, it seems that Huxley, unlike his noble compatriots, was not fearful of Bolshevism. However unlike the socialist intellectuals of his time, Huxley had a realistic, bleak vision of the future of Bolshevism.

Optical Mice :: Free Essay Writer

Optical Mice School of Polytechnic Studies Department of Industrial & Engineering Technology COMPUTER PERIPHERALS A mouse is a device, or computer peripheral, lets a user control a cursor that allows data to be manipulated without having to use complicated keyboard commands. The mouse, though probably named mouse because of its appearance, was originally called an X0Y Position Indicator. Douglas Englebart, who worked for Stanford Research Institute, in 1963, invented the mouse, as we know today. The device didn’t become widely used an appreciated until 1973, when Xerox applied it to their Alto computer system. The mouse was also widely used in Apple computers and is now found on every computer today (Computer Hardware, www.computerhope.com/help/mouse.htm). If you look to the diagram to the right, you will see four parts track an optical-mechanical mouse’s X-Y position movement. When the mouse is moved the ball moves in the direction of the movement. When the roller rotates, light shines through the openings. This light is detected by two light sensors, which send signals to the computer of the movement. The offset of the light that the sensors receive determines the direction of each axis. So that motion is detected, the ball needs traction between the ball and the rollers, which is a major drawback to this design. A pure optical mouse works a little differently. Optical Mice need special grids that the sensor inside of the mice needs to see to negotiate motion. When this kind of mouse moves over this grid light from an LED or laser passes over the grid and the lines seen by the sensor. Optical mice are much more accurate judging motion than the ordinary optical mechanical mouse. One drawback to pure optical mice is that they might run into problems with bright lights (Computer Hardware, www.computerhope.com/help/mouse.htm). Optical mice, technologically more advanced and more accurate than ordinary mice, carry a hi-tech price. The average optical mouse runs from $30 to $100. Since a simpler and cheaper peripherals exist, optical mice aren’t used on a wide variety of systems yet. According to PC Data, no optical mice made it into the top 20 sellers list in any given month (ABCNEWS.com). Recently, though, Microsoft has introduced an optical mouse that can be used without grids on any surface. This new mouse has a camera that can take up to 1,500 images per second and has a high enough resolution to read even fibers in a blank sheet of paper (ABCNEWS.

America Is A Nation of Immigrants Essay -- Ethics of Immigration, Cate

For over 300 years, various ethnic, cultural, and social groups have come to this country to seek economic opportunity, reunite with family members, and find a place where they can be free from political and religious persecution. I suspect a majority of American-born citizens believe that immigration is a bad thing in this country that is harmful. Those particular Americans believe that this country is being infested by foreigners who cannot even speak our own language. However, if one were to look at the truth behind these fallacies, he/she would see that immigration is beneficial to our country and should not be abandoned. Instead, it should be increased. Approximately 800,000 immigrants enter the United States each year. Of this number, 480,000 of them are family sponsored, meaning that they are immediate relatives to American citizens, such as a spouse, child, or sibling. Employment-based immigrants total 140,000 each year. This means that they are, â€Å"skilled professionals with exceptional ability and other priority workers, immigrating to jobs for which the U.S. Department of Labor has certified that no qualified U.S. worker is available† (â€Å"Legal Immigration to the United States†). Contrary to popular belief, only 1% of the population constitutes illegal immigrants.

Freefall and Projectile Motion

Freefall and Projectile Motion Introduction and Objectives This lab experiment was done to determine the characteristics of free fall and projectile motion in Physics. The motion in which a body is thrown or projected is called Projectile motion while free fall is any motion of a body where gravity is the only force acting upon it, at least initially. In this experiment, a photogate, a chopper, and a Universal Lab Interface were used to determine the free fall motion of the chopper as it was released. A ball, carbon paper, and an L-shape projector were also used to determine the range of projectile motion of a ball being released from a horizontal yet slightly vertical slope. At the end of the experiment, one will know how velocity and time affect the acceleration of a free falling object and its projectile motion. Thoery Aristotle stated in his theory of motion that the fall of a heavy object toward the center of the earth is a natural motion because the object is just returning to its natural place. He also stated that heavy objects fall faster than lighter ones because increase in the rate of motion is proportional to the weight of the object. Galileo’s theory states that the when a ball was rolled down an inclined plane at fixed angle? ; the ratio of the distance covered to the square of the corresponding time was always the same, but that when the angle of inclination is changed, the constant also changes but remains the same for the same angle. The constant d/t2 is also the constant for falling object (refers to the acceleration due to gravity). The experimental range used in the experiment is 45 cm, and the expression of the range of the projectile was found in terms of Vg and h. The horizontal distance traveled by the projectile for the total time of flight is given simply by R=vxt where t is the total time of flight and vx is the constant horizontal velocity. The time of flight was found using the equation for vertical motion, which is y=yi + viyt-1/2gt^2. After each experiment, the Logger Pro software determined the curve of the time vs velocity graph to determine which had a better Linear fit, either the Quadratic or the Linear curve. http://physicse-book8. blogspot. com/) Results and Discussion A.

It was shown that under the influence of gravity, an object falls on its own with its velocity accelerating at a constant pace. It is said that when the only force acting on an object is the Earth’s gravitational force,it is in free fall. There cannot be any other force acting upon it, especially air resistance, which should either be absent or ignored by its minute size. The force of gravity on an object is nearly constant when the object in free fall is near the earth’s surface. Because of this, the object accelerates downward at a constant rate. This acceleration is usually represented with the symbol g. In this experiment, a precise timer was connected to the computer and a Photogate was used to measure the acceleration due to gravity. â€Å"The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. † A Picket Fence or a chopper, a piece of clear plastic with equally spread out black sections on it, was dropped. As the Picket Fence passes through the Photogate, the computer will measure the time from the leading edge of one bar blocking the beam until the leading edge of the next bar blocks the beam. † This timing continues as all eight bars pass through the Photogate. From these measured times, the program will calculate the velocities and accelerations for this motion and graphs will be plotted. http://www. waukeshasouth. com/physics1/photo. html http://www. oppapers. com/essays/Picket-Fence-Free-Fall/567967
