The US Environmental Protection Agency Essay Example for Free

The US Environmental Protection Agency Essay The US Environmental Protection Agency, USEPA or more commonly referred simply as the EPA, is federal agency responsible for the protection of the natural environment for the protection of human health and ecology. It was established under the President Richard Nixon in December 1970 and is currently being headed by Administrator Stephen L. Johnson (EPA, 2008a). The EPA acts through twelve administrative offices and ten regional offices: the administrative offices are in charge with the development and assessment of policies and regional offices are the serve as the primary executive arm of the agency (EPA, 2008b). Prior to the establishment of the agency, there was no national structure for addressing environmental concerns, develop legislation and management programs or to implement corrective measures. The EPA implements and monitors compliance to environmental protection statutes it establishes or as passed thorough by federal legislation (EPA, 2008a). Shortcomings of the agency are viewed not only as a failure of related policies but also an indication of the political will, ethical standards and social concern for the protection of the environment (Heilprin, 2008; Marris, 2007; Morrissey, 2008). Case in point: when policies are considered to be restrictive to industries, this relegates the ethical cost of violation of EPA regulations, encouraging subterfuge if not blatant opposition to policies. On the other hand, hesitation on the part of the EPA to implement polices and prosecute offenders diminishes the public’s interests and violates its functional mandates. Moreover, as Pelley (2008) and Sood (2008) have highlighted, the EPA’s mandate is extends far beyond its functions. It is designed to delivery in its fullest extent the intention behind environmental protection legislation and to provide framework standards of environmental and social responsibility.

Euthanasia Essay - The Truth About Assisted Suicide :: Euthanasia Physician Assisted Suicide

The Truth About Assisted Suicide      Ã‚  Ã‚  Ã‚   This essay recognizes that it is hard to tell the truth about assisted suicide. Or rather, it's hard to get people to listen. Folks generally are about as eager to delve into the issue of assisted suicide as they are to work out the details of their own funeral. It's a delicate and unnerving subject, involving the ultimate issues of life: the reality of human mortality; fears about illness, disability, and old age; and the loss of loved ones to the dark, dank grave. Nonetheless, this essay intends to tell all these things, since they relate to euthanasia/assisted suicide.    Simply getting people to pay close attention to assisted suicide - to grapple with its threat - is often a challenging task. This is even true of people who are religious or prolife, whose faith informs them that death isn't the end but the beginning. I understand the emotional dynamic at work. Life is difficult and worrisome enough without visiting the painful realm of assisted suicide. It is difficult even for deeply religious people, to listen, to heed, and to care enough to become involved. But avoidance of the assisted-suicide issue is a luxury that those who believe in the infinite value of all human life can no longer afford, because battles over assisted suicide are being waged - and more battles planned throughout the country.    Tragically, one major battle has already been lost: Oregon legalized assisted suicide in 1994 and the law went into effect in September 1997. Today in the U.S. a small number of physicians participate actively in their patients' suicide, and it is absolutely legal. On the bright side, since 1997, when Oregon's voters refused to repeal the state's assisted-suicide law, a broad-based national coalition of diverse groups has formed to oppose the death agenda. Disability-rights activists, advocates for the poor, professional associations in medicine and law, and hospice organizations - all of which tend' to be liberal and secular - have joined with religious people and traditional prolife activists to oppose medicalized killing.      And this collaboration has borne fruit: Since 1994 five states (Maryland, Rhode Island, Louisiana, Iowa, and Michigan) have passed laws explicitly making assisted suicide a crime, while Virginia outlawed it as a civil wrong, subjecting anyone who assists in a suicide to civil litigation. In November 1998, Michigan's voters rejected an initiative to legalize suicide by an overwhelming 71 to 29 percent.

Aol time warner

The merger between the AOL and Time Warner is most certainly a challenging undertaking. To mix a traditional culture existing at Time Warner as ‘old’ company with the flexibility of the ‘new’ AOL culture was both risky and promising.The merger promised Time Warner entrance into the new digital markets where it lacked expertise and created synergies to consider. As a leader in interactive services and owner of powerful Web brands, AOL could deliver performance in areas that promised the greatest growth in the years to come. At the same time, Time Warner with its large asset base created a climate in which AOL would have resources for the realization of the most ambitious projects and undertakings.The choices vary depending on the degree of freedom companies want to have in their operations. On the one hand, AOL and Time Warner could remain to function as two separate entities, undivided by controversies. In this case, the merged company would only engage in c ost-saving and some cross-marketing strategies to increase the profits of shareholders.On the contrary, the company can choose to undertake a massive cultural overhaul in order to blend the two parts closer together. This choice is extremely risky as the two cultures represent different poles of managerial culture.In my opinion, the first choice is the most rational as both companies would need time to understand what they are dealing with. Previously functioning as part of either AOL or Time Warner, the two executive teams have elaborated their own approaches and positions, and bringing those closer together would be difficult.Both companies would thus have more time to study each other’s business models and learn the best aspects of culture and business practices. The restructuring has to be carried out proportionately to the size of both companies, or, alternatively, inclusion of executives from each company on the board could be equal. In this way, the merger would respec t both cultures and give them time to adjust to each other. Â  

The Women Of The Early Religion - 1492 Words

Ruiwen Chu Paul Tchir 10811862 Assignment 2 Nov 2, 2015 The Women States in the Early Religion The woman as a divine being and a consolidator of every belief that adheres to divinity is defined and explained in both Karen Christina Lang’s Images of Women in Early Buddhism and Christian Gnosticism and in Elaine Pagels’ The Gnostic Gospels. As analysis of religious beliefs, the works define the religious and cultural relevance of the woman in the origins of both Buddhism and Gnosticism, as well as the effects that the patriarchal society has changed in this original belief system. Both literatures assert that the role of the woman in religion serve the purpose of being the divine – or the evidence that Gnosticism is a symbol of the feminine, of celebrating the woman as the most significant element that created the world view as well as beliefs. The traditions set forth by both Buddhism and Christian Gnosticism all adhere to the celebration of the woman, her power, her purity, and her importance in shaping the world, and the men who have to purposely oblige to this belief and to create the tradition which the community should follow. Hence, both Lang and Pagels identified that woman, in her own vestal powers, is the main exhibitor of religious participation as well as the symbol of wisdom in humanity. Lang (1982) defined that women were subjected as the fall of humanity despite being the original images that women has portrayed from Buddhist and Gnostic texts: a) woman isShow MoreRelatedReligion And Public Life : Early Traditions Of Black Religious Women s Activism882 Words   |  4 PagesBoth of these extraordinary women barley came from anything but made it their business to cause change for generations to come.

Winds and the Pressure Gradient Force

Wind is the movement of air across the Earth’s surface and is produced by differences in air pressure between one place to another. Wind strength can vary from a light breeze to hurricane force and is measured with the Beaufort Wind Scale. Winds are named from the direction from which they originate. For example, a westerly is a wind coming from the west and blowing toward the east. Wind speed is measured with an anemometer and its direction is determined with a wind vane. Since wind is produced by differences in air pressure, it is important to understand that concept when studying wind as well. Air pressure is created by the motion, size, and number of gas molecules present in the air. This varies based on the temperature and density of the air mass. In 1643, Evangelista Torricelli, a student of Galileo developed the mercury barometer to measure air pressure after studying water and pumps in mining operations. Using similar instruments today, scientists are able to measure normal sea level pressure at about 1013.2 millibars (force per square meter of surface area). The Pressure Gradient Force and Other Effects on Wind Within the atmosphere, there are several forces that impact the speed and direction of winds. The most important though is the Earth’s gravitational force. As gravity compresses the Earth’s atmosphere, it creates air pressure- the driving force of wind. Without gravity, there would be no atmosphere or air pressure and thus, no wind. The force actually responsible for causing the movement of air though is the pressure gradient force. Differences in air pressure and the pressure gradient force are caused by the unequal heating of the Earth’s surface when incoming solar radiation concentrates at the equator. Because of the energy surplus at low latitudes for example, the air there is warmer than that at the poles. Warm air is less dense and has a lower barometric pressure than the cold air at high latitudes. These differences in barometric pressure are what create the pressure gradient force and wind as air constantly moves between areas of high and low pressure. To show wind speeds, the pressure gradient is plotted onto weather maps using isobars mapped between areas of high and low pressure. Bars spaced far apart represent a gradual pressure gradient and light winds. Those closer together show a steep pressure gradient and strong winds. Finally, the Coriolis force and friction both significantly affect wind across the globe. The Coriolis force makes wind deflect from its straight path between high and low-pressure areas and the friction force slows wind down as it travels over the Earth’s surface. Upper Level Winds Within the atmosphere, there are different levels of air circulation. However, those in the middle and upper troposphere are an important part of the entire atmospheres air circulation. To map these circulation patterns upper air pressure maps use 500 millibars (mb) as a reference point. This means that the height above sea level is only plotted in areas with an air pressure level of 500 mb. For example, over an ocean 500 mb could be 18,000 feet into the atmosphere but over land, it could be 19,000 feet. By contrast, surface weather maps plot pressure differences based at a fixed elevation, usually sea level. The 500 mb level is important for winds because by analyzing upper-level winds, meteorologists can learn more about weather conditions at the Earth’s surface. Frequently, these upper-level winds generate the weather and wind patterns at the surface. Two upper-level wind patterns that are important to meteorologists are Rossby waves and the jet stream. Rossby waves are significant because they bring cold air south and warm air north, creating a difference in air pressure and wind. These waves develop along the jet stream. Local and Regional Winds In addition to low and upper-level global wind patterns, there are various types of local winds around the world. Land-sea breezes that occur on most coastlines are one example. These winds are caused by the temperature and density differences of air over land versus water but are confined to coastal locations. Mountain-valley breezes are another localized wind pattern. These winds are caused when mountain air cools quickly at night and flows down into valleys. In addition, valley air gains heat quickly during the day and it rises upslope creating afternoon breezes. Some other examples of local winds include Southern California’s warm and dry Santa Ana Winds, the cold and dry mistral wind of France’s Rhà ´ne Valley, the very cold, usually dry bora wind on the eastern coast of the Adriatic Sea, and the Chinook winds in North America. Winds can also occur on a large regional scale. One example of this type of wind would be katabatic winds. These are winds caused by gravity and are sometimes called drainage winds because they drain down a valley or slope when dense, cold air at high elevations flows downhill by gravity. These winds are usually stronger than mountain-valley breezes and occur over larger areas such as a plateau or highland. Examples of katabatic winds are those that blow off of Antarctica and Greenland’s vast ice sheets. The seasonally shifting monsoonal winds found over Southeast Asia, Indonesia, India, northern Australia, and equatorial Africa are another example of regional winds because they are confined to the larger region of the tropics as opposed to just India for example. Whether winds are local, regional, or global, they are an important component to atmospheric circulation and play an important role in human life on Earth as their flow across vast areas is capable of moving weather, pollutants, and other airborne items worldwide.

The Content Of A Video Based On A Practical Intervention...

The following report seeks to summarise the content of the video based on the topic selected from the assigned chapters 11 and 12; ‘anchoring’. The first section will summarize the content of the video and examine the concept used to explain the ‘anchoring’ principle, specifically using it in a practical intervention for the British Heart Foundation. The report will then go on to describe the application of the principles of â€Å"Made to Stick† by Chip Dan Heath used in the project, focusing on the implementation of the principles throughout the video. Section 1: (Summaries the content of the video) + provide additional information Anchoring is defined as a process where â€Å"different starting points yield different estimates, which are biased toward the initial values† (Tversky and Kahneman, 1974). The British Heart Foundation was selected as an organisation for a practical intervention. The project focused on their website and how anchoring could be used to increase donations for this charity. Anchoring is frequently used in marketing campaigns and pricing strategies; the iPad launch by Apple in 2010 was used as an example of best practice in our video. The original clip of the iPad launch was first shown as a concrete and credible example of anchoring, followed by a reenactment of a possible board meeting at the Apple Headquarters.

The Harnswell Sewing Machine Company free essay sample

This paper aims to support Natalie York, the operations manager at Harnswell Sewing Machine Company (HSMC), in her intent to improve product quality in the company. In addition to analyzing production process data of half-inch cam rollers and explaining the results, this paper also gives advice on which actions Natalie should take and how she should approach the CEO and founder of her company. Phase 1 Based on the given description of the HSMC, points 1, 2 and 7 of Deming’s 14 points for management seem to be most lacking in the company. . Create constancy of purpose for improvement of product and service. 2. Adopt new philosophy. 7. Adopt and institute leadership. There is a huge need of organizational transformation in the HSMC and its CEO and founder, Mr. Harmswell, is currently not aware of this need. According to his own words (â€Å"if it ain’t broke, don’t fix it†), he is not striving for constant improvement and does not act proactively. We will write a custom essay sample on The Harnswell Sewing Machine Company or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Rather than supporting his employees in thinking about how to improve their working environments, Mr. Harmswell relies on his past experiences. He even actively discourages his employees from â€Å"making waves† and uses fear as an instrument to paralyze the people in his organization (â€Å"What am I going to do with you if you keep coming up with these ridiculous ideas†). This indicates that he is rather supervising than leading his employees. Natalie York should think very carefully about her next steps and focus on the specific problem she discovered and not the whole production process when she approaches Mr. Harmswell next time. Natalie will only be able to implement changes when she comes to her boss backed with profound data analysis. Besides the data-based evidence of problems in certain parts of the production process, Natalie should show Mr. Harmswell the positive impact changes will have on the profit of HSMC. Keeping her language simple and her explanations easily understandable is another key for the success of her next steps. After Natalie successfully implemented a couple of smaller changes in parts of the production, Mr. Harmswell might rethink his attitude towards constant improvement and give her more freedom to have a positive impact on the organization. Phase 2: Using the given data about the diameter of cam rollers, we use Minitab to create a â€Å"Xbar-R Chartâ€Å", as shown in Chart 1 of the appendix. From this chart, we can draw the conclusion that Day 17 is below the LCL, out of control limit. Therefore one can say the whole process is out of control. Natalie notices that the average diameter of batch 17 is extremely low compared to the average diameters of the other batches. Our recommendation to Natalie is that she should check what happened on Day 17 to find the reasons for these out-of-control-results. As the next step, Natalie should take the required actions for solving the discovered problem. Phase 3: After Natalie’s further investigation, it turns out that the reason for the particularly bad results of work on Day 17 is the low temperature in the morning on which the batch was produced. By installing a thermostat in the manufacturing hall they solve this problem. Now, what Natalie should do next is to take this special batch out of the data and draw another Xbar-R chart. After excluding this special case from the data, Natalie can evaluate the rest of the data independently from this â€Å"special event†. The new Xbar-R chart shows this one special batch is not the reason why cam rollers always fall short. From the new chart, Natalie might identify what might be the other causes that result in the shortage. For further information, please refer to Chart 2 in the appendix. Natalie and Jim install the thermostat and set the heating control so that heats turns on half an hour before the machine starts to work in the morning. These actions have a positive impact on improving the product quality as the scrap defects were caused by cold temperatures, affecting the normal running of the equipment. After setting the heating control, the machine will warm up to acceptable temperatures in the cold weather. By doing this, any scraps caused by the abnormal status of the equipment in cold weather will be avoided. Phase 4: Chart 3, the histogram of diameters, and Chart 4, the stem-and-leaf display, show that the range is from 0. 5072 to 0. 5077, which means all cam rollers meet the lower specification of 0. 5072 but some exceed the upper specification 0. 5075. The mean of the 150 sample diameters’ is 0. 5075. The mean diameter equals the upper limit of the diameter. There are 71 cam rollers having a diameter of 0. 075, accounting for 47. 3% of all samples; 49 cam rollers have diameter of 0. 5076, accounting for 32. 7% of all samples; 7 cam rollers have diameter of 0. 5077, accounting for 4. 7% of all samples. Chart 5, the pie chart of distribution of diameters, shows that there are 56 cam rollers which have a larger diameter than 0. 5075, while there are only 23 cam rollers wi th diameters below 0. 0575. 56 of the 150 rollers, comprising 37. 3%, are above the specification value. Therefore 37. 3% of them will be reclassified into a different and less costly category, which decreases total revenues and profits of HSMC. If this percentage is applied for the total years’ production, out of 7000 cam rollers 2614 will not be available for sale at normal price. Phase 5: Dave Martin, the machinist at HSMC, is already aware of the reasons why he has been producing many oversized cam rollers. With operating room of 0. 0003 inch, he has been aiming for the upper level of diameter because he did not want to produce undersized cam rollers which have to be scrapped. Dave Martin simply did not want to have trouble with Mr. Hanswell and other senior managers of the company. Natalie first needs to persuade Dave to adjust his aim to the exact center value and try to manufacture accordingly. Of course, Natalie needs to give Dave an assurance that he would not be held liable for the results. Because Natalie already has all the data she needs to conform to her forecast, we think it is time to go to Mr. Harmswell. She should show him that there exist some real problems and tell him the importance and positive benefits of adopting changes at HSMC. But she should be very careful not to overload her boss with too many graphs and numbers.

Natalie notices that the average diameter of batch 17 is extremely low compared to the average diameters of the other batches. Our recommendation to Natalie is that she should check what happened on Day 17 to find the reasons for these out-of-control-results. As the next step, Natalie should take the required actions for solving the discovered problem. Phase 3: After Natalie’s further investigation, it turns out that the reason for the particularly bad results of work on Day 17 is the low temperature in the morning on which the batch was produced. By installing a thermostat in the manufacturing hall they solve this problem. Now, what Natalie should do next is to take this special batch out of the data and draw another Xbar-R chart. After excluding this special case from the data, Natalie can evaluate the rest of the data independently from this â€Å"special event†. The new Xbar-R chart shows this one special batch is not the reason why cam rollers always fall short. From the new chart, Natalie might identify what might be the other causes that result in the shortage. For further information, please refer to Chart 2 in the appendix. Natalie and Jim install the thermostat and set the heating control so that heats turns on half an hour before the machine starts to work in the morning. These actions have a positive impact on improving the product quality as the scrap defects were caused by cold temperatures, affecting the normal running of the equipment. After setting the heating control, the machine will warm up to acceptable temperatures in the cold weather. By doing this, any scraps caused by the abnormal status of the equipment in cold weather will be avoided. Phase 4: Chart 3, the histogram of diameters, and Chart 4, the stem-and-leaf display, show that the range is from 0. 5072 to 0. 5077, which means all cam rollers meet the lower specification of 0. 5072 but some exceed the upper specification 0. 5075. The mean of the 150 sample diameters’ is 0. 5075. The mean diameter equals the upper limit of the diameter. There are 71 cam rollers having a diameter of 0. 075, accounting for 47. 3% of all samples; 49 cam rollers have diameter of 0. 5076, accounting for 32. 7% of all samples; 7 cam rollers have diameter of 0. 5077, accounting for 4. 7% of all samples. Chart 5, the pie chart of distribution of diameters, shows that there are 56 cam rollers which have a larger diameter than 0. 5075, while there are only 23 cam rollers wi th diameters below 0. 0575. 56 of the 150 rollers, comprising 37. 3%, are above the specification value. Therefore 37. 3% of them will be reclassified into a different and less costly category, which decreases total revenues and profits of HSMC. If this percentage is applied for the total years’ production, out of 7000 cam rollers 2614 will not be available for sale at normal price. Phase 5: Dave Martin, the machinist at HSMC, is already aware of the reasons why he has been producing many oversized cam rollers. With operating room of 0. 0003 inch, he has been aiming for the upper level of diameter because he did not want to produce undersized cam rollers which have to be scrapped. Dave Martin simply did not want to have trouble with Mr. Hanswell and other senior managers of the company. Natalie first needs to persuade Dave to adjust his aim to the exact center value and try to manufacture accordingly. Of course, Natalie needs to give Dave an assurance that he would not be held liable for the results. Because Natalie already has all the data she needs to conform to her forecast, we think it is time to go to Mr. Harmswell. She should show him that there exist some real problems and tell him the importance and positive benefits of adopting changes at HSMC. But she should be very careful not to overload her boss with too many graphs and numbers.
