...Standards In order for a hospital to be eligible for reimbursement through Medicare, they have to show that they are compliant by way of the Conditions of Participation. One way to show this is by getting an accreditation through The Joint Commission who meets the Medicare Condition of Participation standards. (La Tour, 2013). Clinical Quality Medical professional should select quality measures for reporting such as commonly treated conditions, the types of care that are frequently delivered, the settings in which care is given, quality improvement goals and other quality reporting options that are available or being considered. A couple of options available are Physician Quality Reporting System and Value Based Purchasing. Both programs are based on quality of care rather than the amount of services they may provide. (CMS, 2014) Reimbursement for Healthcare Services Currently Medicare’s reimbursement for service is by the Prospective Payment System. This system is based on a fixed amount for the service provided and also based on the classification of where the service was provided as well. For example, Medicare will provide payment for both the operating and capital-related costs of the acute care hospital as well as the long-term care hospitals. (CMS, 2014). Patient Access to Care When everyone works together to coordinate the patient care, the patient receives better quality care and everyone will see a decrease in costs. Here are just a few options available...

...“Rabbits and Wolves” Introduction I will be conducting a computer simulation called “Rabbits and Wolves”. In this experiment I will be interaction with a simple forest ecosystem model that will simply take into account three organisms: rabbits, wolves, and grass. As defined by “Environmental Science- 14th Edition”, an ecosystem is “a set of organisms within a defined area or volume that interact with one another and with their environment of nonliving matter and energy.” I will be using the computer simulation to alter the interactions of the organisms in the ecosystem to see what changes occur. Based on mathematical formulas and probability of certain events occurring, the model predicts the changes in the populations of the three organisms. I will be able to change different variables, such as the starting number of organisms, the reproduction rate, the food consumption rate, the growth rate, and more. I will be able to analyze the data I gain from this simulation to observe how changes in an ecosystem can alter the organisms that live in the ecosystem. Objectives 1. To view and interact with a simple scientific computer model. 2. To determine how simple changes in populations of one organism will effect populations of organisms in the same system. 3. To use a computer model to complete objective 2. Hypothesis I believe that allowing a greater number of rabbits in the beginning of the simulation will allow the rabbits to out-populate the wolves to a very large...

...Bertie Barfield ENG/115 Determining the Causes and Effects of Water Pollution in Lake Huron The Great Lakes, Lake Erie, Michigan, Huron, Superior, and Ontario, are our largest freshwater system. Lake Huron, like the other Great Lakes contain many species of wildlife, and is in danger of being polluted. This pollution is harmful to fish, wildlife stocks, and to the humans of this region. At the University of Mississippi, Latham, A., Wright, E., & Tsang, A. [n.d.] produced a study that focused specifically on Pollution's Effects on the Great Lakes Ecosystem. Determining the causes and effects of water pollution in Lake Huron may facilitate new ideas and solutions for cleaning up our waterways’ and improving public health. Although there are many causes of Lake Huron’s pollution, most fall under three categories: 1) Point-source pollution; 2) Nonpoint-source pollution; and 3) Air pollution. Point-source pollution refers to mercury, fecal matter, and sewage, from treatment plants or industrial facilities, being dumped into the Lake. Nonpoint-source pollution refers to runoff of polluted water from crops or lawns which contain contaminants. These contaminants may be oil, sand, salt from roadways, agricultural chemicals, and nutrients and toxic materials from urban or rural areas (The Lake Huron Centre for Coastal Conservation, 1998-2012). Additionally, air pollution is also a major concern. According to the Lake Huron Centre for Coastal Conservation, “…the...

...March 2, 2013 – The Everglades Flood Control and Restoration: A Century of Disaster OUTLINE ABSTRACT ……………………………………………………………………………………………… Before drainage of the Everglades began over a century ago, the wetlands of southern Florida were an interconnected hydrological assortment of lavish freshwater lakes and streams, cypress swamps, secluded estuarine lagoons, freshwater sloughs, tree islands, wet prairies, and mangrove swamps spanning 3.6 million hectares. After a century of intrusion, the daunting task of understanding, fixing, maintaining, and regaining a sustainable, natural Everglades-type ecosystem in South Florida is monumental. The area south of Lake Okeechobee now has a human population of over four million people, with greedy agricultural and urban demands for more water and more space. Therefore, several uphill battles have ensued. The conceptual plans for restoring this ecosystem, currently on record, are all extremely expensive to implement. A more thorough definition of the environmental and societal objectives and measures of success are required. How the ecosystem will respond to the return of a more natural hydrological pattern is uncertain, but needs to be addressed as the expected and desired outcome through measures of performance. The critical level of deterioration of the Everglades has created a crisis-management atmosphere instead of a full spectrum response and future prevention methodology. The political and social aspects of the Everglades...

...The Burmese Pythons 11/05/2015 period 2 Lexi DiBenedetto The Burmese pythons in the Everglades has become a rising subject. The snakes have created a difference in the Everglades ecosystem. The Burmese pythons are invading and demolishing our ecosystem in the Everglades. The Burmese pythons are not a native animal to Florida. They are actually from Southeast Asia. The Burmese python is a powerful snake that can grow up to 23 feet long. At full growth they reach weights as much as 200 pounds. “The pythons are extraordinary breeders, with a voracious appetites to match (New York Times).”The Burmese pythons eat birds or small mammals but they can eat something 5 times their own size. Even though the python has poor eyesight the snake still has a very effective hunting and killing ability. The python has chemical heat receptors on the back of their jaw. That way they can sense when a warm blooded animal is near them. Then the python snaps at the mammal coils around it and suffocates it until it dies. This way the python can eat it one bite. The Burmese python is a very unique reptile....

...2. Briefly describe what you believe is a major domestic problem confronting the United States - socially, economically or in health care. Indicate how you think this problem should be resolved. Pollution is becoming closer to put life on the verge of death. Pollution is the contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems. Even though some pollution across the whole world is caused by the forces of nature, the majority comes from every day human activities and advancement in technology. Human contamination of Earth can take many forms such as water pollution, air pollution, noise pollution, soil pollution, solid waste, and hazardous waste. These harmful actions have changed Earth, and they continue to do so today. Among them all, I believe that water pollution is most potent to life on Earth. Water pollution is the contamination of water bodies and any change in water quality that negatively affects any living organism. Water pollution is usually caused by human activities such as the removal of sewage, industrial wastes, and agricultural chemicals. Water pollution is also caused by atmospheric deposition, eutrophication, radioactive waste, and global warming. It affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, including humans, but also to the natural biological...

...Unit/Theme: Introduction to Basic Concepts of Ecology Standards: Region: USA- NAS- Science Education Standards National Academy of Science Type of Standard: Science Content Standards Grade Range: Grades 5-8 Content Standard: Life Science Area- POPULATIONS AND ECOSYSTEMS: A population consists of all individuals of a species that occur together at a given place and time. All populations living together and the physical factors with which they interact compose an ecosystem. Populations of organisms can be categorized by the function they serve in an ecosystem. Plants and some micro-organisms are producers--they make their own food. All animals, including humans, are consumers, which obtain food by eating other organisms. Decomposers, primarily bacteria and fungi, are consumers that use waste materials and dead organisms for food. Food webs identify the relationships among producers, consumers, and decomposers in an ecosystem. For ecosystems, the major source of energy is sunlight. Energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis. That energy then passes from organism to organism in food webs. The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid...

...Policy Studies at Yale, Northern Rockies Conservation Cooperative Murray B. Rutherford Yale School of Forestry & Environmental Studies, Northern Rockies Conservation Cooperative Kim Ziegelmayer Yale School of Forestry & Environmental Studies Michael J. Stevenson Yale School of Forestry & Environmental Studies Most professionals beginning their careers in species and ecosystem conservation conceive of their future work in terms of hands-on tasks in the field (“doing something important in the real world”). Whether on the domestic or the international scene, typically the forester sees themselves laying out timber sales, the fisheries biologist looks forward to surveying streams, and the range specialist expects to be classifying grasslands. Current curricula in most universities largely mirror this common view. We train future foresters to address logging problems in the Pacific Northwest or in the tropics, or conservation biologists to design a reserve or study an endangered species. But in actual practice, most professionals spend only part—and sometimes a small part—of their time attending to technical tasks in the field. Professionals, over a career or a lifetime, participate in many activities well beyond fieldwork, and there is much more to building a successful professional practice today than skills in technical work in the field. But what specifically are these other activities? What theories, approaches, and skills are needed to be successful? What are the standards...
