Global Warming Prevention Essay Example | Topics and Well Written Essays - 1000 words
Global Warming Prevention - Essay Example Industrialization has caused us to increase the amount of fossil and carbon based fuels we burn. Coal, oil and natural gas are great sources of energy because they produce massive amounts of energy from a small volume of matter. Unfortunately, these carbon-based fuels produce carbon dioxide as a waste product. Carbon dioxide is a green house gas. It traps the earthââ¬â¢s heat and keeps it in the atmosphere much the same way a blanket hold in heat from the human body in a bed. Too much carbon dioxide is like sleeping under a thick blanket on a warm night. Too much heat is trapped, resulting in an uncomfortable situation. A minority of scientists feel that human sources of carbon dioxide have little or nothing to do with global warming. They point to the geologic history of earth and show times that earth was much warmer than it is currently. Interests, such as oil and gas companies, that want to continue to drill for and consume fossil fuels at the current levels, often support the se scientists. Countering these industry scientists are many brave individuals. Al Gore said, ââ¬Å"Scientists around the world are sounding a clear and urgent warning. Global warming is real, it is already underway, and its consequences are totally unacceptable (Anderson, 2009).â⬠Most independent data shows that global warming is being driven by human activity, so the most important thing we can do in this generation is develop practices and technology that lessen human impact on the global climate. The first course of action we must undertake to prevent further warming is to lessen the amount of greenhouse gasses entering the atmosphere. This is not a simple job because much of our modern lifestyle depends on burning fossil fuels. The largest amounts to fossil fuels are burned to transport goods and people and to produce electricity. Reducing the amount of fuel used in these two processes will greatly reduce the amount of carbon dioxide entering the atmosphere. For electric al power generation, we need to derive more of our energy from renewable resources such a wind and solar power. Many electrical power plants burn coal because it is cheap and easy to obtain. Solar and wind power are more expensive because the technology to generate electricity this way is fairly new (Roberts, 1994). Research and development monies must be spent so that photovoltaic solar panels and wind turbines can produce electricity more efficiently. Greater efficiency will result in reduced cost. Some skeptics argue that these technologies only work when the wind is blowing and the sun is shining. They say that this is not reasonable because an energy supply must be constant. Improvements in storing generated electricity in liquid metal batteries will enable sustainably generated electricity to be produced and then stored until needed. This is an example of how technology can overcome current obstacles to electrical power generation. Providing carbon-neutral transportation will be a bit trickier and require more sacrifice. We are many generations away from being able to produce solar powered cars and trucks. Currently, transportation accounts for over 25% of the fossil fuels consumed globally (Collier, 2007). Clear alternatives, such as hybrid vehicles have grown in popularity and are cutting fuel consumption, but global changes have been

RES675, Version 2 - Written Assignment #1 Essay
RES675, Version 2 - Written Assignment #1 - Essay Example Each part is weighed against generally accepted methods for preparing research articles. The review concludes with the authorââ¬â¢s thoughts about the research methods depicted in the two articles, citing appropriateness of the methods as well as limitations. Research is the cornerstone of any science. It refers to the systematic and purpose-driven process of attempting to gain knowledge about something. Research processes are often documented in journals, which describes the reason for the research, how the research was conducted and the results of the research or study made. This paper looks into two researches conducted and reviews the documented research process contained in the journal article published by the researchers. The first research article presents research done with postcards and looks into its usage as a souvenir, collectible or a means of communication from 1985 until 1920. The research was conducted by Bjarne Rogan, professor of ethnology and culture history at the University of Oslo, Norway. His article on his postcard research was published in the Cultural Analysis journal in 2005. The article describes the researcherââ¬â¢s purpose for conducting the research using present day postcard collections from the period mentioned above. The researcher wanted to look into other aspects of postcards aside from their picture side where more scholarly researched had been focused on. Reviews of previously published articles and literature on postcards are also used by the researcher in order to determine the reasons for the postcardââ¬â¢s popularity during its time, as well as to trace the development of postcards and the evolution of its design during the period. The second research article presents research regarding consumption of energy drink among college students. The research was conducted by Brenda Malinauskas, Victor Aeby, Reginald Overton, Tracy Aeby, and Kimberly Heidal, all professors at East Carolina University

Education leadership Essay Example | Topics and Well Written Essays - 500 words
Education leadership - Essay Example ?s model relies on the personal responsibility of the individual participants within the system to administer the policies that ensure a safe environment to all involved. The first and primary goal is to focus on the end that leads to the maximalization of utility for the learning process. As such, the ways in which strategic goals and plans are implemented are entirely concentric around this. Rather than getting caught up in the minutia that many other educational approaches are so oftentimes ensnared, Clarkââ¬â¢s approach seeks to focus on the end goal as a means of attempting to gain both educator and student buy in for the strategic goals and changes that will be pursued. This model helps to keep both parties focused on the true goal rather than becoming distracted by minutia. What is unique about Clarkââ¬â¢s approach is the fact that many of the positions that may be required at a traditional school such as substitute teachers are not a requirement for his model. Rather, it is beholden upon the other staff members to shift their schedules and classes so that the subject matter can be covered with the class regardless (Clark 2011). Again, this focuses on the personal responsibility framework and encourages educators to not miss a single day of class for any reason other than a legitimate one. What is unique about Ron Clarkââ¬â¢s approach to education is that he fully embraces corporate sponsors in attempting to recruit the raw capital that is required to perform the educational experimentation and development that his model encompasses. Although many forms of education have actively sought to separate themselves from such ââ¬Å"corporateâ⬠sponsorship, Clark has embraced this due to the fact that it is highly likely that many of the students that he serves to educate will at least at some point in their life be employed by such a sponsoring entity. In this way Clark does not see that such sponsorship dilutes the educational process; rather, it is a form of

Mendel Genetics Using Brassica Rapa Research Paper
Mendel Genetics Using Brassica Rapa - Research Paper Example Through the experiment, the hypothesis that the presence of purple pigment is dominant and the trait follows Mendelian laws will be tested. Through analysis of the experimental data collected revealing the dominance of the purple stem trait and a literature review of qualitative and quantitative data, the result will be analyzed to determine if the hypothesized prediction that the phenotypical ratio of 3:1 is established, in accordance with the Mendelian laws. ... Materials and Method To conduct this experiment, heterozygous P Brassica rapa seeds were planted on day one and cultivated in 28 by 55 centimeter plastic pots in an artificial soil compound of an equal mixture of peat moss and vermiculite and watered with distilled water on regular intervals (6). The plants were grown at a controlled temperature of 32?C under regular illumination from fluorescent lamps (7). The seeds, potting soil, and planters were the materials used for this portion of the experiment. The genotype of the parent plants used was F1, Non-Purple Stem, and Hairless. One parental plant was true breeding and green and the other parental plant was true breeding and purple. Once the seedlings began to sprout on the fourth or fifth day, the numbers of purple and green stem phenotype was recorded. The plants began to flower between days nine and eleven and were cross pollinated on day fourteen. Seed pods began to appear on day twenty-one, at which point they will be collected and germinated in the same manner as the parent plants. The number of purple and green stem phenotypes will be counted among the F1 generation to ascertain whether they follow the Mandelian principles. The seeds will appear above ground and will be collected, allocated, and counted according to the number of total seeds that germinate and the stem color of the seeds that germinate.

Print Ad Analysis Essay Example | Topics and Well Written Essays - 500 words - 1
Print Ad Analysis - Essay Example The advertisement I have chosen is just like that- it depicts a company of three friends driving a cabriolet in some desert like area and having fun. They are screaming, shouting, and singing drunk with new possibilities. I have noticed that the whole advertisement presupposes motion as all the people on the image are moving. A young boy in his twenties is evidently spending time with his two friends in a trip to the ocean. The advertisement can be interpreted as a call to adventures and taking risks because youth is what usually pushes people to try something new all the time. The motto of the whole Levi`s campaign is ââ¬Å"I will not sit at home collecting dustâ⬠and by this slogan the brand explains that it creates roadwear ââ¬âthe clothes perfect for movement and ready for any challenges like getting dirt ad washing. If we recall that jeans were initially invented as the trousers for cowboys so they had to be extremely long lasting, than it is getting clear why Levi`s has chosen such style. The time when men were riding wild young horses and felt adrenalin in their blood has passed. Today many young people prefer the comfort of their bedrooms to real adventures. That is why Levi`s creat ing the advertisement which visually appeals to movement, changes, and challenges wants to recall young people what they were made for. Another noticeable element of the advertisement is the spirit of friendship. There are two boys and one girl in the car and they are literally on the same wave of future adventures. Levi`s emphasizes this team spirit on all images of their campaign- people ready to share time and emotions together, ready to have joy and support each other in critical situations. What stops most of us from going on a long trip around the country? The absence of a good company mostly. And Levi`s tries to show that it is rather easy to find those who will be there for you especially is your share common tastes in fashion. Therefore,

Explanation of Roper et al's Activity of Living Essay
Explanation of Roper et al's Activity of Living - Essay Example Other underpinning theories including dignity, consent, and privacy shall also be discussed in this paper as they relate to better and effective nursing care. Although not all of Roperââ¬â¢s activities of daily living apply to this case, they shall nevertheless be included for discussion purposes. This paper is being carried out in order to establish a clearer picture and understanding of Roperââ¬â¢s activities of daily living and the impact of disease, disability, and infirmities on such activities. Body The patient is a 55-year old Afro-Caribbean male who was admitted to the hospital after suffering a fall secondary to excessive alcohol intake. He also has Type 2 diabetes as his other co-morbid condition based on his previous medical history. He lives alone after his wife divorced him two and a half years ago. He is also unemployed because he lost his driving license three years ago and has since sought solace in alcohol which he initially thought he could control. Roperâ⬠â¢s Activities of daily living 1. Maintaining a safe environment Maintaining a safe environment is crucial for this patient. Patients who have experienced falls are likely to fall again because of any injuries they may have suffered and any immobility which their fall might have caused (Lord, et.al., 2007). Maintaining a safe environment includes safety precautions which can be made on the home and in the patientââ¬â¢s hospital room. Guard rails on the bed have to be put up, especially in instances where the patientââ¬â¢s mental awareness is low (Miller, 2008). Since the patient is suffering from excessive alcohol intake, the guard rails need to be put up in order to prevent any repeat falls. Maintaining a safe environment also requires the nurses taking on leadership roles in order to maintain and monitor standards which can secure the cleanliness and effective infection control measures (Smith, n.d). The care administered to the patient therefore includes various remedies i ncluding infection control as well as monitoring of patient progress. Maintaining a safe environment for the patient also includes the process of ensuring that the nurses have the sufficient skills and training to care for the patient and administer to his needs (Smith, n.d). Such safe environment also includes working in partnership with health professionals in order to deliver adequate patient care (Smith, n.d). Ensuring a safe environment also includes the process of effective communication with the patient, gaining their consent before interventions are carried out (Department of Health, 2010). Maintaining a safe environment for the patient also involves patient education, teaching the patient about the dangers of alcoholism and any further injuries he may suffer due to his intoxication. It is also important to educate the patient about his disease and the risks he is taking with his alcohol intake (Gonzalez, et.al., 2005). Any injuries he may suffer would also likely take a lon g period of time to heal because of his diabetes. Maintaining his privacy at all times is also part of the safe environment created for the patient, ensuring that he can trust the nurse and his dignity can be respected at all times (Department of Health, 2010). 2. Communication Since the patient is still in the throes of his alcoholic stupor, there is a communication barrier between the nurse and the patient. When he was sober, there were no apparent communication bar

Controversial Issue of Use of Cookies in Web Browsers Essay
Controversial Issue of Use of Cookies in Web Browsers - Essay Example Many internet sites have incorporated cookies in the search engines for various purposes. Usage of cookies is more prevalent in e-commerce sites, which depend on the activities and information of the customer to customize the search engine to the preferences of the customers. Cookies store small sections of program codes and memories that can be retrieved later. Use of cookies is always well-intended. However, there has been claims that site owners use cookies to track important information from the users. This is even more controversial considering that cookies operate discreetly without the knowledge of the user. Whether use of cookies is beneficial or risky to internet users has remained a controversial issue for a long time and therefore, this paper explores this controversy and ultimately supports that use of cookies is indeed beneficial to internet users. Proponents of use of cookies argue that use of cookies makes site browsing easier, more efficient and user-friendly. Accordi ng to Palmer ââ¬Å"while e-commerce has grown rapidly in recent years, some of the practices associated with certain marketing aspects of marketing such as pop-ups, cookies and spam have raised concerns on the side of the internet usersâ⬠(Palmer, 2005). For instance, e-commerce sites such as Amazon use cookies to keep track of user activities. User information is recorded and kept as cookies, site preferences are recorded as well as credit card and vital personal information. Users do not have to re-enter such information in subsequent site visits, therefore, making browsing easier and safer. However, it is possible for some sites to use such information unethically. For instance, site preference information can be used for advertisement purposes and not necessarily to benefit the site user.Ã
