Critical Analysis - Essay Example In this paper, the authors report on the effects of PDNF on tyrosine hydroxylase (TH) activity, a rate-limiting enzyme during the synthesis of dopamine and other catecholamine neurotransmitters. TH is important because it is involved in increasing the production of neurotransmitters. The study came up with the following additional actions of PDNF: Strengths. The paper has many strengths. First, it presented data that was based on solid experimentation that covered a wide range of immunological, molecular, and imaging techniques. The data was clearly presented using graphs and images. The discussion was straightforward and concise. The strongest point of the study is the methodology followed to arrive at the results. The authors arrived at their results through a series of experiments that each showed the action of PDNF on TH. To show that PDNF increased the TH expression in PC12 cells and primary mesencephalic neurons, the authors grew the cells in media that was treated several times with PDNF. Results obtained with immunostains were confirmed using immunoblots. Western blots and SDS-PAGE were also utilized. The study also used a luciferase gene assay to check the effect of PDNF on the promoter of TH. The method used to confirm the mechanism of action of PDNF on TH was done in a simple manner, where a construct of a mutation for the cAMP response element (CRE) labelled with luciferase transfected to PC12 cells. This step was able to show the effect of CRE on the action of PDNF on TH promoter activity. The discussion portion was able to summarize in a clear manner the results of the experiments, and related these to previous work done in the field of TH activation. The paper points to the mechanisms that could explain the action of PDNF. As an example, it was pointed out that PDNF mediated the phosphorylation of serine residues in the catalytic sites of TH. The phosphorylation activity of PDNF was

Target Market Essay Example | Topics and Well Written Essays - 500 words

Target Market - Essay Example From a layman’s point of view, the governmental and institutional sectors provide good growth opportunities. However, on a broader horizon, it can be seen that world markets other than USA provide exponential growth opportunities. These regions include Pakistan, the 2nd largest consumer of CNG vehicles where government has heavily invested in the CNG infrastructure, Bangladesh and India. Due to the increased environmental awareness amongst the target market and the technological innovations which have improved the quality and efficiency of CNG buses to match the diesel buses. Moreover, the experience of Argentina and Pakistan has shown that it is tried and tested and the investment of the investors will not sink. Moreover, it would save the huge bill on fuel and is economical. The present hike in fuel prices (petrol and diesel) is another factor which is in favor of converting fleets to CNG powered vehicles. The common observation is that even though the capital investment on a CNG bus might be US $ 25000 expensive as compared to traditional diesel buses, but the savings due to fuel economy are enough to cover up this gap in as small a time frame as 1 year. Moreover, CNG, contrary to traditional belief, has been proven to be a safe and hazard proof fuel. Considering the above now is the perfect timing to enter into this sector. Considering the above statistics, it can be concluded that Asian markets are the fastest growing markets for the CNG industry. The North and South American regions together hold immense unexploited potential and growth is expected in upcoming years. Growing global markets: the greatest opportunity for CNG Buses is the dynamic growth being experienced in the CNG sector in economies like Latin America (Argentina, Brazil), Pakistan, India, Bangladesh and Thailand. Awareness in Institutional Clients: Over a period of years, the environmental awareness has been increasing. This is

Environmental Economics & climatic change Essay Example for Free

Environmental Economics climatic change Essay Many approaches to green house emissions are currently being examined in the United States. In fact members of the 110th Congress (2007-2008) are actually making legislations pertaining to global changes faster than has even been experienced before having made over 235 bills, resolutions and changes by July, 2008. One such proposal is the cap-and-trade system (Paltsev et al. 4). The cap-and-trade is a piece of legislation meant to identify the greenhouse-gas-emitting bodies it incorporates. It refers to those organizations which introduces caps on the emissions they are responsible for and allows trading in the emission allowances which arise therein (Obama Biden, New Energy for America). They basically stipulate a set of accounting periods allocating allowed emissions for all the periods (Paltsev et al. 4). Cap-and-Trade Legislation; SO2 Program The permit trading programs offer pollution permits to organizations which reduce their pollution discharge lower than the target benchmarks. They are then allowed to either trade them or keep them for use in future (Ludwig 1). Following the Clean Air Amendments of 1990 the U. S put in place the Acid Rain Program to gain a reduction in sulfur dioxide (SO2) and nitrogen oxide (NOx), the main contributors of acid rain (Ludwig 1). The second program was the Hot-spots and acid rain program which basically involves regulatory tiering; embracing more than one regulatory regime at one specific time with the intention of exercising some control on the way permits are made use of (Obama Biden, New Energy for America). The goal of the acid rain program is to reduce SO2 emissions by 50%; a task meant to be accomplished through two stages mandating all organizations to reduce their SO2 emissions (Ludwig 3). The Opt-in program established by the Congress according to section 410 of the Clean Air Act Amendments of the year 1990 was designed with the intention of drawing the SO2 sources with reduced marginal costs of compliance (Ludwig 3). It is important to note however that the permit trading programs are not effectively contributing towards reducing increased emissions. Indeed the acid rain program of the United States has had less and unlikely effects on pollution hot-spots (Ludwig 10). This is quite unfortunate given the main energy challenges facing the U. S, which are foreign oil dependence and global changes in the climate (Obama Biden, New Energy for America). The safeguard the acid rain program makes use of is one of the reasons permit net flows have such a low effect on reducing emission. Alternative Method of Pollution Control It is worth appreciating that carbon trading at the markets was a positive step be it at the global, European or national fronts (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). It was in deed a challenge not only to the government but also to the private sector (Obama Biden, New Energy for America). If the war against carbon emissions is to be worn, a global regulatory framework would be needed (Watson et al 1). This would call for British Government and the World Bank to embrace the same views. This means that the cap-and-trade legislations can no longer offer the best solution to the problem. What is needed is a different approach, an alternative way of reducing carbon emissions. In light of the climatic changes being experienced, carbon emissions should be reduced by all chances (Obama Biden, New Energy for America). This calls for a new trading strategy; an approach which is more inclusive likely to involve all ventures emitting carbon such as aircrafts and ships (Watson et al 1). In the private sector this would call for a wider long-term market approach, voluntary in nature working to achieve public and private interests. The Kyoto Protocol should be strengthened coupled with better implementation of the Clean Development Mechanism (CDM) (Watson et al 1). Indications of progress are beginning to be seen with incentives for reducing emissions, development of alternative technologies as well as investments attraction (Watson et al 2). There is also the need for better liaison with the UN system more so in helping poor countries with their emission problems (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). This therefore means that carbon taxation is definitely not an alternative solution the emission problems. There is need to invest in fuel-efficient machinery, support domestic energy supply, as well as diversifying the nations’ sources of energy (Obama Biden, New Energy for America). Organizations also need to commit themselves to the course of lowering their energy consumption (Watson et al 2). The Legislation I would Support As an undergraduate in ApEc 3611, I would support the second alternative because it more inclusive, realistic and possibly a better solution since it involves many stakeholders (Watson et al 2). What I imply here is that a new alternative to America’s and indeed the world’s energy problem is an idea whose time has come (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). Energy is a real challenge facing the world and for America, there is even greater need to address the issue because of foreign oil dependence (Obama Biden, New Energy for America). Therefore I support the new alternatives to reducing carbon emissions. The private sector needs to embrace a wider long-term market perspective but within the confines of both the public and the private interests (Watson et al 2). This new perspective calls for more research into the areas of innovative technology as well as new investments. Indeed one of the mid-to-long term proposals to the energy crisis in America is to make investments towards the secure energy future of the nation alongside creating more than 5 million jobs all with the intention of lowering foreign oil dependence (Obama Biden, New Energy for America). Such efforts will greatly reduce carbon emissions besides contributing towards the reduction of the country’s dependence on foreign oil (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). There is need to strengthen the Kyoto Protocol and the implementation of more stringent governance and accountability systems (Watson et al 2). The Emissions Trading System (ETS) needs to be reviewed (Hertel, Global Trade Analysis: Modeling and Applications). This is because for it to be successful, it needs to put caps on emissions. This will create both markets and prices for carbon emission permits (Watson et al 2). I therefore fully support these new alternatives since they offer a more proactive approach to the nation’s energy problems. Cost Benefit Analysis The lake in question is private property if the home owner has the property rights to it. This would mean that as a private good it can only be used by another party if it is paid for. It is the lake owner who would decide whether or not another party uses the lake. For this to happen, the total benefits accrued from the use of the lake will have to supersede the costs of using the same lake thus a Pareto improvement (Oka 18). The lake owner will have to carry out a cost-benefit analysis before he can allow fishing in the lake. This is an evaluation tool to determine if the use of scarce resources will generate efficiency (Fuguitt Wilcox 2). Efficiency is in relation to the lake will be the benefit of peace and quiet at $2,000 per season. It means the benefit of allowing Walleye Wally to use the lake will be $ 2,000. With $ 2,500 he can meet the $2,000 and secure the fishing deal meaning that there will be fishing in the lake. However, with only $1,200 per season, he cannot meet the cost of foregoing the peace and quiet thus there will be no fishing. Assume Walleye Wally had the property rights and the benefits of peace and quiet to the home owner remain unchanged at $2,000. With $2,500 there would be fishing in the lake. The lake owner cannot however pay Walleye Wally not to fish since the cost of paying Walleye would supersede the benefit of peace and quiet, hence there will be no Pareto improvement. If Walleye got $1,200 per season there cannot be fishing in the lake since the benefit of the fishing will be less than the cost and hence no Pareto improvement. This transaction cannot be termed as efficient since one party will suffer loss in the transaction. The principle that by which the concept of efficiency is applied is here is the cost benefit analysis (Oka 19). Conclusion There are factors that would hinder the cost-benefit analysis. For public goods, it is difficult to measure the efficiency concept and the Pareto improvement concept is lost. The consideration of potential value that would be attached to sustainability would make it difficult to make an accurate cost-benefit analysis (Oka 26). In conclusion, cost-benefit is an economic tool used for gauging the efficiency of a transaction in the market economy (Oka 17). With regards to CO2 emissions, there is need for a new direction which will require a more centralized regime; a continual and joint effort between the government, businesses and the people (Obama Biden, New Energy for America).

The American Civil War Essay -- History USA Historic Essays

The American Civil War Works Cited Not Included Horrific! The American Civil War, also known as the War Between States and the War Of Secession, was an extremely gruesome and bloody war (World Book 614). The war, which started on April 12, 1861, when the southern troops fired on Fort Sumter, and ended 4 years later, took more American lives than any other war in history (614). This war was between a divided union in whish the southern states were trying to preserve slavery while the northern states were dedicated to a more modern way of life and were trying to end slavery (614). This war was fought in the minds of great men like Abraham Lincoln and Robert E. Lee and the end of the war was the beginning of a slavery free nation. The American Civil War was a horrible event in the history of the world which started from three main causes: slavery, disputes over states' rights, and because of the division which existed between the South and the North. April 12, 181 was a day that would forever live in the history of the United States. On this day, the Southern troops of the Confederate States fired the first shots of the American Civil War on Fort Sumter in Charleston, S.C. (World Book 614). Before this day, Americans had an abiding faith in the politics and the democratic ideals on which this new country was based. Andrew Jackson described Americans as ?guardians of freedom for the human race.? James K. Polk spoke of the American government as ?This most admirable and wisest system ever devised. Americans, north and south, regarded these statements as true. American politics was a fiercely partisan affair at first. It was all for the good of the new nation. At the close of the 1850?s, citizens wondered if their... ...uence over government policy (World Book, 634). The Northern ideals, however, helped to develop the modern United States as an industrial power (World Book, 634). Slavery was officially abolished after the Civil War in the 13th Amendment to the United States Constitution (World Book, 634). The results were lasting, some severe and big, while some were small and unnoticeable. The American Civil War was a horrible event in the history of the world which started from three main causes: slavery, the dispute over state?s rights, and a division between the North and South. The war ended because of the dedication and warfare tactics of many heroes and enemies. The Civil War started on April 12, 1861 and ended four years later (World Book, 614). In the end, more Americans died than in any other war in history. But in the end good once again triumphed over evil!

Professional Development Plan Essay

When forming teams in a professional work environment it is important to understand the personalities of your teammates to determine strengths and weaknesses. When a leader is able to define the strengths and weaknesses of the team members it is easier to delegate tasks, encourage brain storming sessions and be successful as a team. Team C is composed of five members all with great leadership skills and a desire to learn and complete excellent work together. The first week of class we completed a DISC assessment that identified our individual personality traits. According to â€Å"Disc Profile† (n.d.), â€Å"The initial DISC model comes from Dr. William Marston, a professor at Columbia University in the 1920s, who was curious about the behavior of normal people. He did not create an instrument from his theory, but others did† (Disc Overview). As a potential leader of this team, I was able to examine my own leadership styles and apply that to our assignment which is to create a professional development plan to identify the characteristics of the members to lead them to success. My DISC assessment concluded that I was a Cautious personality type. I see this in my personality. I often think or overthink what I do and tasks that I complete at work and in the school environment. I rarely rush into an assignment or partially complete an assignment. I often am very detail-oriented in projects and assignments. My leadership mentality is mainly to lead by example. I rarely will task another person without knowing exactly what is involved in completing the job. This is probably due to a desire to have control over a situation and know exactly what is involved and how long it will take to complete. Plus I am a person that prefers to build trust by having examples of competent behavior to reference. Three members of my team have the â€Å"Steadiness† personality. Betty, Shawn, and Harlan are more steady and security-oriented, meaning they prefer to know precisely what they are doing as far as job related and school related tasks are concerned. When leading them in the team I would make sure they  understand the assignments of projects we work on as a team and I may be able to help them understand the projects better by fully explaining what we would hope the result would be. This might help team members to have more confidence in the projects. Brian has an interactive personality and it shows as he is able to learn about an assignment and take charge in explaining and delegating tasks for it. Brain is very confident in his assessments of situations and tasks. He has a very good way of being so excited about an assignment that it influences others in a positive manner. If I were to lead this team, I would have to have an understanding of the strengths of Brian’s ability to motivate the team and my ability to help the others understand the project so we may be successful in completion. Betty, Harlan, and Shawn are the key players in this as they will strive to do an incredible job in maintaining a strong will to succeed and complete the tasks. As a general rule, the steady personality listens well, creates very strong relationship bonds and work very well with others (â€Å"Uniquely You†, n.d.). They are able to be objective about situations that other people might not handle well. They can handle stress well and are reliable and really care about others feelings and will often take action that will help others feel good. References Disc Profile. (n.d.).
