Fracking and water pollution Research Paper Example | Topics and Well Written Essays - 750 words

Fracking and water pollution - Research Paper Example fracking fluid, comprising of common toxins and carcinogens such as uranium, lead, mercury, methanol, formaldehyde, hydrochloric acid, ethane glycol etc (Spellman, 2013). Waste water resulting from fracking usually has a lot of potentially poisonous chemicals from the fracking fluid and natural contaminants from very deep in the ground, comprising of totally dissolved solids (such as barium, salts and strontium)radioactive materials like Radium 226 as well as organic pollutants like toluene and benzene. About thirty to seventy percent of all the fluid utilised in fracking is likely to resurface, and thus requires treatment. In addition, fracking discharges â€Å"produced water† mainly from underground which also ascends onto the surface, and mostly can be somewhere from two to two hundred times as much water, something dependent on the water/gas/oil absorption in the shale configuration. It has been proved therefore beyond any reasonable doubt that waste water arising due to fracking has a lot of possibly dangerous chemicals that were used in the fracking liquid, in addition to deep underground natural contaminants (Spellman, 2013). For these contaminants and chemicals to be removed, all techniques of wastewater management (comprising of reuse, recycling as well as injecting into dumping wells) normally entail some kind of treatment. Eventually, wastewater can be pumped to treatment works that are publicly owned or rather to dedicated industrial or brine wastewater plants, also known as centralized waste treatment plants, which might also add precipitation and coagulation methods in removing of dissolved solids. All treatment techniques produce residuals-which basically are waste materials, mainly in sludge, liquid or solid form, that mostly stay after treatment. Because of public concerns regarding the huge volumes of water used in hydraulic drilling, gas and oil fracturing corporations have begun not only reusing but also recycling the wastewater (Spellman,

E-Commerce. The Advantages of Global Education Essay

E-Commerce. The Advantages of Global Education - Essay Example The paper tells that global education is a perspective in education arising from the notion of the contemporary people’s interactions and lives in the ever escalating globalized world. As such, it assists greatly in providing learners with the competencies as well as the opportunities aimed at reflecting and sharing of an individual’s role and an individual’s point of view within the world. In the same point of view, the society is subjected to interconnection and to comprehend this, it is essential that a discussion to point out flaws in variables such as; common social relationships, which are in nature very complex, economic, ecological and political issues, be engaged towards deriving new acting as well as thinking ways. Mobile learning is a contemporary virtue university whose intentions are to offer courses in an eLearning setting to students across the world. Many of the eLearning courses are particularly offered making use of the web only but global educa tion is aimed at making easy access learning irrespective of the location. Global education has a marketing statement which imparts a message that not all can access a computer on a regular basis but presence of mobile phones plays a huge role thereby proving to be important. As such, Global education has an objective of offering eLearning courses that can be easily assessed through internet enabled mobile phones through bite size chunks and paid on the basis of, as you go. However, it should not be considered as an approach that every person should accept without being critical towards it. This is because; there exist tensions, dilemmas, different perceptions as well as doubts in the process of education usually evidenced in dealing with issues in regard to globalization (Schniederjans, & Cao, 2002). Thesis Statement In the light of the contemporary as well as the expected changes in mobile phones, this paper will provide a report on the global education feasibility in implementati on of this ideology. Strengths and challenges of the proposed idea The strength on eLearning using a mobile phone usually lies in the aspect of the communication approach rather than an approach pertaining to contents (Ryu, & Parsons, 2008). As such, the statement is not intended to cause confusion, as it is not supposed to imply that mobile learning cannot have an approach to contents. Technologies within the mobile industry will at the moment as well as in the future tend to be made use of with a content approach but it must be pinpointed out that, mobile learning real advantages lie in the domain of communication (Shah, & Clarke, 2009). As compared to computers, mobile phones are cheaper and very easy to maintain. Due to the current wave of superiority battle among the mobile companies, more and more hi-tech devices are being made and brought into the market at fair prices such that, any person with the money and has the willingness to buy, can afford. As such, this will make the idea of eLearning using mobile phones more easily as it is through the phone that one can sign up or register for a course in any online college which has been accredited and access the learning materials available in those accredited schools (Tsang, Simon, & Victor, 2010) . Learning materials access is made easy by the fact that one can download various files such as pdfs and Microsoft word documents or even reading those documents while still in an online mode (Fred, & North central University, 2008). Again, mobile phones are easy to maintain in the notion of service charges. Using the mobile internet is cheap as it is uses compressed form of browsers. In respect to the access of internet using a computer, it requires one to sacrifice huge amounts of money to set up a continuous source of internet as well as maintaining that internet flow (Quinn, 2011(a). Still, it is an ideal thing that mobile phone

Observing Global Warming & the Harm of It Essay Example | Topics and Well Written Essays - 250 words

Observing Global Warming & the Harm of It - Essay Example Like many are already aware of, carbon dioxide plays a major role in its own right as it comes to the warming of the Earth and the resulting weakness of the global inhabitants that comes as a result of that warming. Another culprit is the continued robbing of the forests through the means of deforestation. Those trees are meant to act in a way that turns the CO2 into breathable oxygen for human consumption. Most importantly, the industrial nature of the modern world has served as a means of killing the natural world that is forced to co-exist with it. The technological desires of mankind have forced the Earth into a tailspin that, if not caught, will continue to force it into a continued destructive phase that will ultimately tear it apart at the core. With the increase in human population and other expansion, it has increased the need for a building that has taken small cities and built them into metropolises of great grander. These Cities feed the advancement of man, without any kind of thought to the environmental damage which is inflicted upon the Earth. As many knows, greed itself sells. Humanistic nature overwhelms, as well as strangles, in most cases, the needs of those things around them, especially in the precious environment that is drowning as each day goes by. The desire of people for their own self-serving interests takes hold and crushes anything in its surrounding path that may interrupt that. As the analysis shows within the presentation, human nature is at the root of the current state of the environment. Humans need shelter to survive and as such trees need to be cut down for the construction of those dwellings. Only those trees are what create the breathing oxygen. Charcoal aids in cooking food, and so much  mo re.  

Offensive strategy options - CostCo Essay Example | Topics and Well Written Essays - 250 words

Offensive strategy options - CostCo - Essay Example Nevertheless, with increased domestic competition within the U.S. retail industry and the maturity of the market, Costco needs to consider other offensive strategies that would not only enable them to improve their market share but also enhance their financial performance. Costco may consider implementing initiatives that capitalize on the weakness of competitors, and/ or pursue end run offensive strategies. The stiff competition in the domestic U.S. retail industry, coupled with the maturity of the market implies that firms should focus on holding and milking their market share (Valdani & Alessandro, 2012). However, Valdani & Alessandro observes that firms may seek to improve their market share in these markets by focusing on the weaknesses of their main rivals. The SWOT matrix rank reveals that Costco is a strong company, which is able to take on their rivals head on. Nevertheless, Costco may direct its internal strength, capabilities and resources towards attacking the weaknesses of its rivals in the U.S. retail market. Costco may achieve this by going after customers whom the competitors are less equipped to serve. It may also attack those rivals offering poor customer services. Alternatively, Costco may expand into regions and market segments where their rivals are either weak or have ignored completely. Apart from capitalizing on weaknesses of their competitors, Costco may consider pursuing end run offensive strategies. The end run offensive strategies enable firms to avoid frontal and head on attacks that may escalate and produce unhealthy competition (Cullen & Praveen, 2013). With the end run strategies, Costco would be able to go around competitors, capture the market segments that are ignored by the rivals and establish the first mover advantage in these markets (Cullen & Praveen, 2013). Cullen & Praveen observes that a company may implement end run strategies in four ways. Firstly,

My Personal Pedagogy Essay Example | Topics and Well Written Essays - 3000 words

My Personal Pedagogy - Essay Example This essay shall demonstrate how my personal philosophy and pedagogy works together to define the kind of teacher that I am and strive to be. It will discuss four aspects of my pedagogy namely assessment, planning, implementation and evaluation as underpinned by my values of being a lifelong learner, being reflective, valuing positive, respectful and harmonious relationships and listening with an open heart and mind (as seen in Appendix 1).Edwards & Nuttal’s (2005) contention is that pedagogy is more than just understanding children and the curriculum and how they fit together to suit children’s learning. It goes beyond that. I agree with them that pedagogy also involves understanding the children’s contexts, personal experiences outside the academic sphere and factors around the wider community (Edwards & Nuttal, 2005). Such a viewpoint elevates the educator as an â€Å"active interpreter†(Edwards & Nuttal, 2005) of the context of children’s learni ng and not a mere interpreter of a prescribed curriculum. As an active interpreter, I believe assessment of children is the keen observation of how children learn, grow and develop and interpret these observations in accordance to the expected developmental milestones for their particular stage of development. It is all about my knowing more about children through noticing and recognizing their learning preferences and disposition for learning (Claxton & Carr, 2004). I try to see how curious, they are and how persistent and open they are in learning what they want. I try to see how curious, they are and how persistent and open they are in learning what they want. My assessment of children is guided by what I know about how they should be behaving, thinking, feeling, interacting, communicating, etc. at their particular age level (Fleer, 2006).I know that even if there are patterns of development, they are still unique individuals who possess their own individual personalities and abi lities. When I do observe them, I gather information about them so I can further improve outcomes for them with the planning that I will do for and with them. My reflection in Appendix 2 shows how I have observed children’s interests to further their learning while it also enhances my own learning. As a teacher, I have engaged in never-ending observation as a way to â€Å"obtain information†, (Quality in Action, 1998, p. 86). This is part of my value of learning. I always strive to be a keen observer as I look into their interactions, choice of resources, use of language (see in Appendix 3). In that reflection, it shows the change in how I believed learning should be, as I used to think it was more academic learning that should be pursued. But working in a real early childhood centre has made me realize that learning is more about child-centred initiations such as engaging in play, arts, sports, etc. to pursue their own interests so they fulfil their hunger for learnin g rather than from a teacher-directed activity, although I am not saying children will not learn from that too. Also in the assessment example in Kei Tua ote Pae (MoE, 2004), I agree what the social-cultural theory (Vygotsky, 1978 ) recommends - an assessment method which gives children the power to set their own goals, assess their own achievements and become responsible for their own learning. This is exhibited in the portfolio of their works which give voice to children’s thinking and abilities (Ministry of Education, 2004, 2005) (see in appendix 4 ). My value for positive, respectful and harmonious relationships also pushes me to observe the children with their families so I am able to see the dynamics of their relationship. Part of my assessment includes that I get to know about the children’s whanau and ask about what goes on in their families in such a way that I maintain a respectable distance so I do not probe too personally (as see in Appendix 5). I agree wit h Rinaldi (2001) contention that making child’

Impact of Positive Airway Pressure Among Obstructive Sleep Apnea Essay

Impact of Positive Airway Pressure Among Obstructive Sleep Apnea Patients - Essay Example This amounted to a study population of 15,424 individuals, who were then followed for a minimum of 12 months and a baseline of 24 months to determine what if any health impact PAP might have been having on treatment. Of those participants, approximately ten percent did not use PAP while the remaining 90% did. Furthermore, the study designers controlled for previous illness by eliminating anyone who had a previous diagnosis of cardiovascular disease, to ensure that these results did not bias the sample. The study measured health effects by measuring the rates of hospitalization among those using PAP to those who were not. They measured this using two different metrics: total hospitalization and hospitalization related to OSA. OSA is associated with a wide number of illnesses, including cardiovascular disease, heart failure, coronary artery disease, cerebrovascular disease, diabetes, and hypertension, so any hospitalization for these reasons (which obviously constitute a large number of total hospitalizations) would be considered OSA related hospitalizations (1). The study found a statistically significant (p

The rewards of living a solitary life by May sarton Research Paper

The rewards of living a solitary life by May sarton - Research Paper Example She notes that the man shockingly discovered that he could enjoy himself alone just as much as he would have been in the company of people (Pike and Acosta). In retrospect, Sarton wonders what the man had been afraid of all along. Nevertheless, having found himself alone, Sarton observes that the man is on the brink of adventure to explore himself and to launch himself into his own inner space. She likens the experience to that of an astronaut in outer space. She posits that the new experience will bring to him freshness that would seem original in the beginning. Moreover, she interjects that anyone able to see for himself using his naked eye becomes a genius for a moment or two. On the other hand, when our perception is influenced by other people’s ideas, the original impact becomes diffused or gets lost (Pike and Acosta). One may ask, are we alone or do we exist as a single cell in a population of a billion other cells in the universe? We may argue that it all depends on what life one chooses to live and what benefits one the most. May Sarton opines that solitude is the salt that flavors personhood. Arguably, solitude helps one discover himself or herself away from the interferences accrued from interacting with other people. She retorts that being alone does not necessarily mean that one is lonely. Furthermore, people do feel lonely even in the company of others. She observes that people feel lonely in the company of their lovers and others because people suffer from their differences in taste , mood and temperament. Human interaction demands that people soften their perception and withdraw at the fear of hurt. However, being alone enables one to explore oneself wholly at whatever place, whichever time (Pike and Acosta). Quite a fascinating luxury, if I may add! May Sarton provides a description of her life and apparently her schedule throughout the day. It
