Energy Sources For Alternative Energy - 930 Words

The constant increase and release of carbon dioxide emissions into our environment have drastic effects on our environment. These greenhouse gases warm the earth impacting its naturally occurring events and processes, such as acid rain, destruction of natural habitats, and even influencing the natural flow of the currents in our oceans. The goal has been to create diverse methods of generating powerful, dependable energy sources that do not have negative repercussions on our environment. Alternative energy refers to sources that do not create undesired consequences, such as fossil fuels do (Alternative Energy 2015). Not only are emissions from fossil fuels concerning, but also these resources are not going to be available for our use forever, making changes for alternative energy sources a pressing topic of discussion. British Petroleum and Royal Dutch Shell, two of the world’s largest oil companies, predict that by 2050, one third of the world’s energy will have to come from some type of alternative energy source (Alternative Energy 2015). Constant growth of population, climate changes, and depletion of fossil fuels makes it necessary for renewables to play a bigger role in powering our world. These resources are often thought to be ‘free’ sources of energy because they are naturally occurring events used to form electric power (Alternative Energy 2015). In addition, all of these forms have a large decrease in carbon emissions compared to conventional energy sourcesShow MoreRelatedAlternative Energy Sources1852 Words   |  7 Pagesmajor problem.

Epidemiology paper free essay sample

Public healthIn a written paper of 1,200-1,500 words, apply the concepts of epidemiology and nursing research to a communicable disease. Communicable Disease Selection Choose one communicable disease from the following list: Chickenpox Tuberculosis Influenza Mononucleosis Hepatitis B HIV Epidemiology Paper Requirements Include the following in your assignment: Description of the communicable disease (causes, symptoms, mode of transmission, complications, treatment) and the demographic of interest (mortality, morbidity, incidence, and prevalence). Describe the determinants of health and explain how those factors contribute to the development of this disease. Discuss the epidemiologic triangle as it relates to the communicable disease you have selected. Include the host factors, agent factors (presence or absence), and environmental factors. (The textbook describes each element of the epidemiologic triangle). Explain the role of the community health nurse (case finding, reporting, data collecting, data analysis, and follow-up). Identify at least one national agency or organization that addresses the communicable disease chosen and describe how the organization(s) contributes to resolving or reducing the impact of disease. By using the scientific method of investigation, health care professionals, including public health nurses, are able to identify the various health needs found within communities and design interventions that specifically target meeting those health needs. Due to close contact with the community, public and community health nurses have an advantage with being able to identify local disease patterns and specific cases, as well as offer education designed to prevent or control specific diseases based on risk factors and other environmental factors (Wissman, 2007). With the predicted growth of the older adult population in the United States, the study of the elderly population is especially important within the realm of epidemiology. The elderly population makes up the fastest growing portion of the population (Stanley, Blair, amp; Beare, 2005) . It is estimated that there will be more than 50 million people over the age of 65 living in the United States by the year 2020 (Abrams, Beers, amp; Beckow, 2000) . Results from the 2010 census taken in the United States reflects that elderly people, or people over the age of 65, make up 12. percent of the total population (United States Census Bureau, 2012) . With cultural diversity also growing at rapid rates, and new health concerns always on the horizon, epidemiology, especially related to the elder population, becomes critically important (Stanley, Blair, amp; Beare, 2005). Steps and Methods Used in Epidemiology The epidemiological process is complex and consists of many steps. The first step is to identify the health related problem and determine its significance. At this stage, the public health nurse gathers data from all available sources and then uses that data to determine the range of the problem. The next step in the process is to develop a theory exploring possible explanations based on the data that has been compiled. From this point, information is sorted and narrowed down, and the validity of the hypothetical possibilities is explored further. The fourth step involves developing a plan designed to control or put an end to the disease process that is being evaluated. During this phase, all influential factors related to the spread of disease are identified and evaluated, and prioritized goals are created in order to halt the sequence of the spread of disease. The fifth step in the process is putting the plan into action by using all available resources. From there, relevant information is obtained in order to evaluate the effectiveness of the plan in preventing the spread of disease. The seventh and final step consists of creating a report of pertinent data, including evaluation of accomplishments and failures, and basing follow-up recommendations and interventions on this information (Wissman, 2007). Each year, seasonal influenza outbreaks threaten populations across the globe. The already vulnerable elderly population is particularly susceptible to succumb to complications related to influenza, especially considering the fact that the average elderly person has an estimated three or more chronic illnesses that compromise an already weakened immune system (Blais, Hayes, Kozier, amp; Erb, 2006). According to the Centers for Disease Control and Prevention, â€Å"Its estimated that 90 percent of seasonal flu-related deaths and more than 60 percent of seasonal flu-related hospitalizations in the United States each year occur n people 65 years and older â€Å" (2011). The CDC advises that the best way to prevent and control the spread of influenza each year is by the use of vaccinnations. In effort to control and prevent influenza epidemics, the CDC uses the epidemiological process to predict the strain of the virus that will be most relevant to the population and this data is used to formulate influenza vaccinations (Centers for Disease Control and Prevention, 2011). Based on the information provided by the CDC and other agencies, as well as data gathered first hand through interaction within communities, public health nurses can advocate for the use of influenza vaccinations by elderly populations. While providing education related to preventive methods and the importance of vaccination, as well as administering vaccinations, public health nurses are key participants in the epidemiological process of seasonal influenza related to the elderly population. In addition, data reported by front-line health care workers can be used by the CDC and other agencies to predict future episodes of influenza and plan for control of outbreaks. Epidemiological Triad A tool that has proven beneficial in field of epidemiology is the epidemiological triad. This triangle shows the relationships that exist between three interrelated factors in relation to the spread of disease: agent, host, and environment. The agent is identified as the disease causing object. The host is a living being that is able to be affected by the agent. The environment is the surroundings inhabited by and further manipulating the host. According to the epidemiological triad, the interaction among the agent, the host, and the environment, all govern the way communicable diseases develop and spread. In addition, the relationship between these three factors also determines the way communicable disease will be prevented or stopped (Wissman, 2007). Disease causing agents can take on many forms. Infections agents include viruses, fungi, and bacteria. Physical agents include genetics, temperature, and trauma. Chemical agents include drugs, toxins, and fumes. Agents affect hosts based on their susceptibility. Hosts that are not susceptible to disease causing agents are determined to be immune by either active means (natural or artificial) or passive means (natural or artificial). Environments consist of physical factors, access to health care, high risk working and living conditions, crowding, temperature, and many other examples (Baughman, 2004). The epidemiological triad can be applied to the elderly population in relation to influenza. In this scenario, the agent is the influenza virus. The host is the elderly person who is either susceptible to the influenza virus or not susceptible after acquiring immunity through the vaccination process. The environment includes factors such as season, temperature, and crowding. Each of these three aspects of the epidemiological triad interacts to influence the ability of the influenza virus to cause disease and spread among the elderly population and subsequently to the population at large. Types of Epidemiology Epidemiology exists in two forms: analytical and descriptive. Analytical epidemiology strives to determine the cause and origin of disease and also explores associations between disease and determining factors such as who is susceptible and why they are susceptible. On the other hand, descriptive epidemiology explores disease in regard to person, place, and time (Stanhope amp; Lancaster, 2012). Analytical epidemiology is used to study the susceptibility of elderly people to the influenza virus. Likewise, descriptive epidemiology is used to describe who is affected and the outcome of the disease. Relationship of the Disease to Levels of Prevention Various levels of prevention exist in order to promote optimal states of health for individuals and populations. Three levels of prevention can be seen in the health care field and they are relevant in the discipline of epidemiology. The first level, or primary prevention, focuses on the prevention of the onset or initial incidence of illness or injury. Primary prevention can be seen in the form of community assessments, provision of immunizations, education related to communicable disease and hygiene, and also nutrition counseling. The secondary level of prevention focuses on the early discovery of disease states and treatment. The goal of the secondary prevention level is to limit the severity of disease and minimize adverse effects. Secondary prevention methods include screenings for disease (cancer, diabetes, hypertension, etc. ), treatment of these diseases, and regulation of outbreaks of communicable disease. The third, or tertiary, level of prevention aims to make the most of rehabilitation following an illness or injury. Examples of tertiary prevention include rehabilitative exercise programs (such as physical and occupational therapy), support groups, rehabilitative clinics (such as congestive heart failure clinics and cardiac rehab), shelters, and case management (Wissman, 2007). In relation to elderly patients and influenza, the levels of prevention are easily demonstrated. Primary prevention methods include education provided to the elderly population regarding the seriousness of the influenza virus, possible complications, and the necessity of vaccinations to protect against the disease. In addition, providing the influenza vaccination to elderly clients is also a primary prevention method because it seeks to prevent disease from occurring. Once disease occurs, the secondary level of prevention can be observed through interventions such as screening to verify the existence of disease (influenza a swab), symptom control, and management of complications (including rehydration, antibiotics for resulting infections, and potential hospitalization). Due to the likelihood of the existence of already weakened immune systems and aging of various organ systems, the elderly are more likely to suffer serious complications from the influenza virus. For example, many elderly patients develop pneumonia as a result of illness. Tertiary levels of prevention in this situation include interventions such as physical rehabilitation and strengthening exercises. Conclusion Epidemiology strives to identify health related events, causative factors, spread and control of disease, and potential eradication of disease. As the elderly population grows exponentially, epidemiology becomes increasingly important in order to assist our older adults with achieving their greatest health potential. Influenza is a disease that has a heavy impact on the elderly sector of the population. Through the utilization of epidemiology, we have the ability harness the influenza virus and improve outcomes for the elderly, as well as the entire population.

Sobering Studies essays

Sobering Studies essays A new study found students who doubt their abilities to handle bad moods or bad situations are more prone to drinking. This is just the latest in a number of alcohol studies coming out in relation to college students. College students are always easy targets for these surveys, since many students are finally away from their mother's nest for the first time and feel free to go out more times than Friday and Saturday nights. What is obvious is there are as many reasons or excuses to drink as there are drinks themselves. People drink to relax, have fun, deal with stress, sleep, get away from problems, cope, and alleviate stress, just to name a few. What students should be aware of is if they are drinking for more than relaxation and fun, they could very well have a problem. In essence if students are drinking to cope with the everyday problems of academe, they have more problems than low grades or job market stress. On the other hand, just because someone drinks more than one glass of wine for dinner doesn't make that person a problem drinker. If everyone who drank at Penn State went to an alcohol counselor, the lines would dwarf those apparent for this year's Penn State-Michigan game. What students (as well as everyone else who drinks) need to realize is that drinking is not a solution to any kind of problem. Alcohol, like caffeine, nicotine and heroin, is a drug. Beverage companies can paint them any color they want, but nothing is going to take away that fact. Like any drug, alcohol is potentially addictive. The best test is to figure out whether you use the drug, or the drug is using you. As the summer is in its midst, more students will be inclined to drink after the stress of finals and even graduation. Don't let the summer become an excuse to drink more heavily than other times. Despite increasing publicity about the problems caused by student drinking, a new survey suggests that the number of ...

Operations Management - Essay Example The international nature that is evident in the markets as well as competition has made many of the companies that operate globally to make reviews to their operations strategy and the companies are thus moving from the centralized operations to the decentralized ones so that they can benefit from the accessible resources while being closer to the markets. The organizations have also made several changes in the approaches, techniques and operations they employ with the goal of meeting the evolving requirements associated with the market. Companies therefore have to be in competition on the basis of more than one competitive performance goals that include quality, cost, receptiveness, suppleness as well as reliability.Mass customization has therefore developed to be a key goal as in many of the companies and the organizations are developing the build-to-order supply chain so that it can be flexible and responsive. To accomplish mass customization, the build-to-order model has to be ac tively implemented in a variety of industries, company like BMW allows the customers to make changes to the vehicles that they want within six days of the final assembly and this includes an entire change in the colour of the car. This enables the company for example, to build more than half a million permutations of the Z3 since they can be tweaked to the customer’s specifications in the event that he or she wants adjustments.As a result of the escalating international competition as well as a decline in the profit margins.

For this purpose, both of them recruit graduates for their trainee programs. In order to place them on management or professional posts, both organizations have training programs. For the recruitment of graduates, both Goldstan and Hodell use visits and advertisements within universities in Yorkshire. Whereas, Goldstan further utilizes local newspapers and recruitment consultants in this regard, while Hodell utilizes professional journals and it also takes help from advertising. The Goldstan asks it applicants to submit the application form that is filled in by hand, not type written or printed. On the contrary, Hodell has adopted a very catchy technique to attract the graduates since the 1970’s. The company provides brochures to graduates that talk about the advantages of working with the organization and the prestige of the company. It requires Curriculum Vitae of the candidate with a covering letter. The selection process at Goldstan undergoes a single panel interview. The Head of the Department or Human Resource Manager conducts the interview where the recruit is required. The interviewee is asked to give a fifteen minutes presentation on a specific issue following the interview. If the candidate is found satisfactory with his performance and capabilities, then the employment offers are made. On the other hand, Hodell holds two interviews with the candidates. The first interview is conducted by the Human Resource Manager while the second one is conducted by the Head of the Department or with the senior employee / staff member of the department where the vacancy is available. Following successful interviews, the candidate is then supposed to complete personality and intelligence tests. Once the candidate passes these

Presidential Contenders 2008 Essay Pre-election convention of the Democratic Party will pass on August 28 in Denver. The tensest conflict of the elections is between the candidates of the Democratic Party B. Obama and H. Klinton. The representative of Democratic Party will get the victory at the basic elections as Republicans have lost considerable support among the population because of wars in Iraq and Afghanistan. Besides, there is the crisis of crediting of a category subprime, which led to unemployment’s growth and to substantial damages of the companies. That’s why the results of the primaries are significant. Barack Obama won Wisconsins and Hawaii’s primaries on Tuesday, which extends his winning tendency and makes him hard to surpass in the remaining sixteen races. Clinton hasnt won a contest since Super Tuesday on Feb. 5. On Wednesday Obama picked up the support of the 1. 4 million-member Teamsters, his fourth labor endorsement in a week. Union support is expected to be key in the upcoming Ohio and Pennsylvania races. Clinton is behind in delegates, and the gap has been growing. She has to win fifty seven percent of the remaining primary and caucus delegates to erase Obamas lead, a daunting task requiring landslide-sized victories. According to some information, up to primary elections in Wisconsin Obama had on the account 1281 voices of party delegates at main congress whereas Clinton was the second (1218 voices). In Wisconsin 74 voices were played. In total the candidate from democrats have to get support of 2025 party delegates for promotion. Therefore the basic struggle still ahead. Obama also won â€Å"the Democrats Abroad global primary† on Thursday, giving him eleven straight wins. â€Å"More than 20,000 U. S. citizens living abroad voted in the primary, which ran from Feb. 5 to Feb. 12.

Clinton is going to establish a deadline for the American troops in Iraq. She will begin dialogues with Iran and she will try to limit Chinese imports to the American market probably to avoid recession. The race for democratic nominee isnt over yet the future situation can not be predicted exactly. Bearing in mind the trend of Obama’s winning the primaries will continue to show the desire of the American people.
