Solar energy Research Paper Example | Topics and Well Written Essays - 1500 words

Solar energy - Research Paper Example Solar energy is the power that is produced directly by the sun and collected somewhere else, mostly on the Earth. The sun is the nearest and biggest star and the source of energy for the planet of Earth. The sun's energy has been in use for a lengthy time, and it is a critical part of life. The solar energy is a fundamental need for humans. The image of the sun has many theories, histories and myths associated with it. For centuries, it has been the God, or the holy part of different religions, for example, the American native tribes and Greeks worshipped it. It is also an essential part of many religions as they hold it dear to their worship, for example, Hinduism, Buddhism and druids of England hold the sun as the precedence of their existence. It is a fact that without the solar energy, human life would be inexistent. Sunlight is crucial as the living organisms circle around it for survival. According to Mahaney (10), plants depend on sunlight for photosynthesis to take place, thu s, helping in their growth while, on the other hand, providing food for animals. The sun and other stars are, in essence, responsible for providing human beings with energy. In the current climate, mounting power requirements and escalating environmental worry, unconventional to the exploit of non-renewable and polluting relic fuels, have to be scrutinized. An instance of energy that requires to be investigated is the solar energy (Tiwari 199). The sun produces its energy by a thermonuclear process that converts several tons of hydrogen to helium each second. The procedure produces heat and electromagnetic radiation as the sun retains the heat, which is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation is distributed and streamed out into space in all directions. These rays entail noticeable and infra-red, as well as ultraviolet, light. From the radiations produced, only a little fraction manages to penetrate, and reach the planet Earth (Mahaney 4 ). The radiations reach the Earth in a form of indirect source of nearly every type of power used today. The only form of energy that does not rely upon solar energy is the geothermal energy and nuclear fission and synthesis. Even fossil fuels are reliant on the sun for their energy, as they were once live creatures and plants that utilized solar energy for their survival. Table of world energy usage as per the year 2000 Energy source Solar energy Electricity Fuel oil Liquefied petroleum other percentage 51.2 30.3 9.3 6.5 1.9 The table above shows world consumption rates of different sources of energy. Solar energy is the most utilized one followed by electricity, according to the table. The world’s most needed solar energy can easily be harnessed and completed by solar power. Much of it can also be supplied indirectly. Because of its nature, solar energy requires two components for it to perform; these are the collector and the storage unit. The radiations are gathered by th e collector as they fall on it and convert a fraction of the radiations to other varieties of energy, such as electricity and heat. The storage unit holds the excess energy produced at maximum productivity and discharges it when the productivity falls. The storage unit is necessary because of the inconsistencies of solar energy (Tiwari 192). Solar energy is one of the most plentiful sources of energy, which is easily available to

How does the democratic leadership style affect the work environment Thesis

How does the democratic leadership style affect the work environment in school - Thesis Example In a school, democratic leadership has a vital role to play and it is important that the people closest to the students, get the opportunity to make decisions on school curriculum and instructions. Coalition principles state that the school itself "should model democratic practices that involve all who are directly affected by the school" In a democratic setup, students, teachers and parents could have various insights, thoughts, ideas and talents which when shared would be so effective in creating a healthy school culture. It is vital to start democratic leadership while children are still in school, as schools play a crucial role in preparing citizens for democracy. According to Nancy Mohr -"You can do anything you want: you just can't do everything you want". The positive side of limited time is that it forces schools to make choices that correlate with the core values of the school resulting in teachers, students and parents-the decision-makers experience commitment that   surp asses their personal fortune. In a democratic set up, one does not think and act individually for ones self, but on the other hand think and work for the whole group. This vision is clearly reflected in the words of Anzar's Charlene Mckowen where she states "Once you've worked here, (democratic set up) you always think on behalf of the whole staff, the whole school. You think for the long term when you're a part of making a decision". Accomplishing a democratically run school can be very difficult. But once it is achieved, the needs of the whole community can be met and there is a good chance that the school will retain itself even with the loss of its key visionaries and founders. Democratic leadership  places key decision making in the hands of people who know the students best and which makes it a powerful tool to serve the common good. Educational leadership in the 21st century shows patterns of change, conflict and contradictions. The need for effective leadership is being cl amored for, by all quarters, be it the teacher, politician or the parent. The topic of democratic leadership has always been a highly debated one and has surfaced time and again in the arena of educational research. One of the foremost advocates of this system is John Dewey who opined that for students to become able citizens of a democratic society it was important that they lived and grew up in a democratic educational environment along with their teachers. Democratic leadership plays a very vital role in all the facets of our life, especially education. According to (Gastil, 1994) it is both crucial and essential to understand the meaning of democratic leadership, but currently not much attention has been paid to it. In (Minier, 2001) opinion, democratic movements have been responsible for the historical progress of democracy and there are many great leaders of the world who have contributed a great deal to democracy, freedom, liberty and human rights among the developing countri es. These dynamic leaders have fought against dictatorship, racial problems involving discrimination and segregation, and military regimes and were instrumental in promoting democracy and bringing about good social change. (Fox & Brown, 2000; Wiseman, 1996) According to (Bass,

The interview Essay Example | Topics and Well Written Essays - 250 words

The interview - Essay Example This fact is true since in most cases, experience and ability to effectively carry out a task can only be accessed by examining the recognition, attitude, knowledge, and professionalism of the candidate (Carless & Waterworth, 2012). Interview allows for the contacts between the candidate and the firm representatives, thereby making this evaluation possible. In most situations where the firm intends to retain top talents and build a reputation, sufficient time limits and effort are required from both parties. However, during the selection of the potential employees, the human resource department remains very keen on the every component of the required skills and qualification of a candidate. As stated by Boswell (et al. 2003), personal interview acts as a bridge that must be crossed by the candidate in order to move from being a job seeker to a new hire. As a candidate approach interview with utmost impressions and glitters of hope, the company, on the other hand, keenly approaches the recruitment process with an awareness of the financial side of employment. Thus, the interview provides a chance for an individual to confidently enter the workforce of the firm. In addition, successful hiring requires more than just examining ideal resume, but needs conversations and personal interview in order to access the candidate’s capabilities and compatibility to the organization’s culture.

Offender Recidivism and Employment Essay Example | Topics and Well Written Essays - 6250 words

Offender Recidivism and Employment - Essay Example aper aims to discuss about offenders on supervision and how their employment status determines their success on supervision and their recidivism on re-offending. Determining the proper response to the re-offending behavior of criminals has plagued governments, criminologists, the judiciary, and the community for some time. A precise figure for the rate of recidivism cannot be ascertained, as much crime goes unreported and the courts do not convict all offenders for various reasons, including lack of evidence. Rates of recidivism also depend on what measures are used in terms of the time frame considered and whether one is concerned about particular offences, re-arrest rates, or re-imprisonment. There are many factors that contribute to the re-offending behavior of an individual. Many prisoners have poor education and employment histories, experience greater rates of mental illness and bad physical health, and have issues associated with drug and alcohol misuse. The effect of prison or jail sentences on recidivism is an important issue to those concerned with public safety and the cost-effectiveness of putting convicted offenders in prison. Opinions are divided between those advocating longer sentences in the interest of public safety, and those advocating shorter sentences with the assumption that incarceration, or longer prison terms, will not reduce recidivism rates. This paper summarizes the theories and the empirical studies on this issue. Study findings indicate that the effect of incarceration (versus other sentencing options) and sentence length on recidivism is complex and is likely to be offender-specific. For some offenders, incarceration and longer confinement seem to increase the risk of recidivism. For other offenders, the likelihood of re-offense will either be unaffected or reduced by longer terms of incarceration. Furthermore, early-release programs do not appear to affect overall recidivism rates. It is well recognized tha t offenders have a high
