The Truth to the Puritanism Lifestyle in American Literature Essays
The Truth to the Puritanism Lifestyle in American Literature There are many suspicions about weather Puritanism is accurately depicted in books. This should clear things up a bit. The depiction of the puritan life style in American Literature is in some ways inaccurate but it is mostly accurate. The Puritans' were very religious but their family and social traditions were vaguely addressed. In literature such as The Scarlet Letter, The Crucible, "Sinners in the Hands of an Angry God", "The Devil and Tom Walker", the Puritan lifestyle is mostly accurately depicted even though some things were left out. These accurate depictions and mostly reflected in crime and punishment, good and evil in society, religious influence, and family and social traditions. In literature, such as The Scarlet Letter and The Crucible, crime and punishment were depicted as harsh and unusual, and they were in some cases but, in many cases the punishments were suitable to the crime committed. There is however truth to the stories, there were public confessions, and public punishments. Crimes were not as heavily judged by biblical standards as The Scarlet Letter and The Crucible lead the reader to believe. Judges were not quite as amiss as the stories elude them to be. Good and evil in society was also ill addressed. The puritans know that good and evil was amongst them but it did not run there lives as it was portrayed in the stories. In the Scarlet Letter the characters Roger Chillingworth and Arthur Dimmesdale were the epitome of good and evil. Roger was often referred to as the devil and Arthur was a man of God. In The Crucible witches were everywhere they believed that witches were terrible beings and yet everyone was susceptible to being over ... ...y depicted in the Scarlet Letter but in the book there were not as many sermons or lectures as there were on the true Puritan Election Days. In a nut shell the Puritans? way of life, in American Literature, was portrayed in a slightly harsher manner then the reality of it, but all in all the books were surprisingly accurate. There were certain aspects of puritan life style that were scarcely mentioned and some that were not mentioned at all. There is a great deal to learn about the Puritans and American Literature can only teach a brief synopsize about it. Works Cited Helicon. "Sinners in the Hands of an Angry God."

Energy Drinks Essay
Something I learned in my last Health class is the ever-increasing use of todayââ¬â¢s new ââ¬Å"Energy Drinks. â⬠Caffeine is the single most used drug in America. How many of us must have that morning cup of coffee before heading out the door? How many college students are staying up late at night preparing for a mid-term or final exam by drink these new, all natural, safe, energy drinks? You may want to read their labels and adjust your thinking. You may want to include a little research in regards to these drinks. At this time there is no long-term research to report on in regards to energy drinks. What we do know is that these drinks have a variety of ingredients such as ginseng, amino acids, ginkgo, various vitamins, and high amounts of sugar. However, the primary active energy ingredient is caffeine. At this time, the FDA does not regulate the amounts of caffeine that are in these drinks. They suggest that within a 12-ounce beverage serving the amount of caffeine should be 68 milligrams or less. A report published by the Journal of Analytical Toxicology showed that of ten of the most popular energy drinks had as high as 141 milligrams in one 16-ounce serving. The following 12-ounce energy drinks showed, Monster at 120 milligrams, Red Bull at 116 milligrams, and Amp contained 107 milligrams of caffeine. To give a comparison, look at Coke and Pepsi. They only contain between 34 to 38 milligrams of caffeine. Energy drinks have risen significantly in popularity in the last few years with revenues exceeding $3. 5 billion a year and growing. One report states that with the new found popularity there are growing concerns of the possible health effects among children, adolescents, and young adults. It states that 30 to 50 percent of America drinks energy drinks. Of this amount they report that one third are from the ages of 12 to 24 consume these beverages on a daily basis. Due to these beverages being chilled makes them easier to consume quickly. High doses of caffeine have been linked to seizures, cardiac problems, mood or behavioral disorders, and diabetes. Additionally, these problems have been linked specifically to the consumption of energy drinks among children, teens, and young adults. There has been a growing concern amongst the medical community, parents, and school officials in regards to these energy drinks on our youth. Numerous reports are being found to the adverse affects these high caffeine drinks are responsible for. The Illinois Poison Control Center reported in a recent survey of more than 250 cases of caffeine overdose in a three-year period. The average age of these accounts was 21. A doctor from California reports that an eighteen year young man received treatment for an abnormal heart rhythm after consuming eight 16-ounce energy drinks per evening to remain alert during his night job. Another growing concern is the use of these energy drinks as a mixer with alcohol. A study from 2006 showed that the individuals surveyed were just as impaired in motor coordination and reaction time as individuals drinking alcohol alone. As stated earlier, there is not much evidence on the effects of long-term use of caffeine on children or teenagers. It is known that it can create physiological and psychological dependence in adults. This being true, we must do everything possible to protect our children from these non-regulated beverages. We need to insist on more research to be conducted in order to better inform the public of the consequences of the consumption of these highly-caffeinated energy drinks and the adverse effects they have on our youth.

Thin Film Solar Cell
Abstract: Solar energy is quite simply the energy produced directly from the sun and collected elsewhere, namely the Earth. Photovoltaic technology directly converts solar energy into electricity. Photovoltaic thin film solar cells are easy to handle , inexpensive and also easy to use. Thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. This paper will discuss the advantages and disadvantages of the thin- film solar cell and also describe its application and how its work. Introduction: The solar cell is the latest technology around the world. The solar cell is also called a renewable energy source, because the capture the sunlight and convert it into the electrical energy. There are different types of solar cells, but the most important one is a thin- film solar cell. It is cost effective and its efficiency is greater than the other types of solar cells like thin film dye sanitized solar cell . Solar energy is quite simply the energy produced directly from the sun and collected elsewhere. All solar cells are made of silicon. Thin- Film Photovoltaic technology directly converts solar energy into electricity. Solar cells are made out of semiconducting material, usually silicon. The process of making a solar cell begins with taking a slice of highly purified silicon crystal, and then processing it through several stages involving gradual heating and cooling. Solar cells are based on semiconductor physics ââ¬â they are essentially just a P-N junction photo-diodes with a very large light-sensitive area. Another common material for thin- film cells include Gallium Aarsenide (GaAs), Copper Indium Gallium Selenide, and gallium Phosphide. The most common types of photovoltaic cells are single-junction, multi-junction, and thin-film. A thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. Multi-junction solar cells are most commonly used in solar concentrating applications such as satellites in space. Today we use solar power to do many things. We use solar power for everything from calculators to large power plants that can power large cities. The most common applications for solar panels are used for small evices. The Solar cell technology research is continuing to create low-cost high-efficiency elements and the latest approaches in solar cell designs. Some countries do not have oil or do not have enough political and economic power to buy it or to produce it, but they receive more sunlight than others. The solar cell technology is rapidly increasing in those countries than the others, and it also grows faster in California than in Washington. Polycrystalline thin-film solar cells are based on those compounds which have the efficiencies up to 19. 2%. Nowadays, it is increased by 20. 4%. The Swiss Federal Laboratories for Material Science and Technology has recently developed a new thin-film solar cell with an efficiency of 20. 4%. Those cells are based on CIGS (copper indium gallium (DI) selenide) semiconductor material. The band gap on the top of the solar cell around 1. 6-1. 8 EV. The thin-film solar cells should be design by single-junction and also two- junction devices commonly used CIGS and CdZnTe. There are four different types of thin-film solar cell. 1. Amorphous silicon (a-Si) 2. Cadmium telluride (CdTe) 3. Copper indium gallium selenide (CIS/CIGS) 4. Organic photovoltaic cells (OPC) How Thin-Film Solar Cell Works: Thin-film solar cells are also called new generation of solar cell. This cell contains multiple layers of PV material. This new generation solar cells produce over 3700 megawatts of electrical energy in 2010. The main difference between the structure of normal silicon solar cells and thin film silicon solar cell is the thin flexible arrangement of the different layer as is shown as figure (1). The only advantage of that layer is to create a greater surface area for sunlight absorption and also it is very low weight and easy to use in cars and small devices. Figure (1) We use calculator everyday in our normal daily routine. These solar powered calculators have a small solar cell at the top corner of the calculator. These cells are built with thin ââ¬âfilm technology. Most of them are very small about an inch long and ? inch wide. The thin-film solar cells are very thin thatââ¬â¢s why they Called thin-film solar cell. Thin-film solar cell is different than the silicon wafer. Silicon wafer and thin-film solar cell have a light absorbing layer, but only difference is the thickness. The silicon wafer has 350 microns thick,but the thin-film solar cell has only one micron, and as result thin-film solar cell is very light weight compared to other solar cells. Thin-film solar cells are made of several layers. Those all layer helps to absorb light. As you can see in the figure (2). (Different layers in thin-film solar cell) Figure (2) On the other hand, some thin-film solar cell required the three functional layers from the multiple layers in a solar cell. These three have different important function. In the figure (a), show the front contact and back contact layers which have only one job to do and thatââ¬â¢s is to provide the electrical contact with the solar cell from the outside the world. The figure (a) shows the basic theory of the different layer stack of the thin-film solar cell. Thin -film solar cell implemented by the different ways , but the three most common inorganic technologies are CuSe2 , CdTe solar cell, and also thin-film solar cell which has an amorphous and microcrystalline silicon absorber. There are three major types of thin-film solar cell. 1. Amorphous silicon (a-Si) 2. Cadmium Telluride (CdTe) 3. Copper indium gallium deselenide (CIGS). The (a-Si) solar cell is very commonly used and also easy to understand and implement it, but there are two major problems that cause this type of solar cell to have some drawbacks. The first problem is, silicon is very hard to find the market and buy it , because its demand often exceeds the supply. The second thing is, this type of solar cell has very low efficiency. This type of solar cell is also very thinner so they absorb sunlight in very less and on the other hand, they do not have enough power to absorb more. Therefore, they used in calculator and other very small and low power consuming devices. The Advantages of Thin-Film Solar Cell:1. Thin-film solar cell is very cheaper than the silicon solar cell2. They are also available in thin wafer sheet.3.More flexible and very easy to handle it.4. Less thinner than crystalline solar cell. It can be as thin . 001 mm or more, but the crystalline solar cells are . 15-. 2 mm thick.5. Easy to install on the rooftop with a rugged mounting system with tilt at a fixed degree.6. Thin film solar cells have better performance in the hot weather. See table (1) below.Table (1) | The efficiency of solar panel /%| Temperatur e /degree| a-Si thin film| Crystalline| 25 (STC)| 10| 16| 35| 8| 11| 45| 6| 6| 50| 5| 3. 5| The Disadvantages of Thin-Film Solar Cell: 1. Less efficient than the normal standard silicon and crystalline solar cell. See table (2) below. Table (2) Condition| Crystalline Efficiency Drop| Light San Francisco fog| 8%-15%| Heavy San Francisco fog| 15%-20%| Cloudy & raining| 20% ââ¬â 50%| Heavy cloudy & raining| 50% ââ¬â 90%| 2. They have complex structure. 3. Different version requires its own unique installation skills. 4. They are also not available for aerospace applications. 5. They faster to degrade than the other solar cells thatââ¬â¢s why they always come with a shorter warranty. 6. They require a huge space so they are not good for most residential situations. Applications Of Thin-Film solar cell: Thin-film solar cell panels are used in many power applications. They are also used for outdoor and energy generating applications. These cells are very light weight and easy to use in homes and small business. They can be installed on the rooftops of the most homes. They use calculators, cars and other portable electronics. They are also used in cloths also enables the powering the iPod, iPad, and cell phones during the hiking. Thin film solar cells are used in mobile charger and led lights. Conclusion: The advancement of Photovoltaic thin film solar cell is increasing rapidly. The development and decisions on materials used in PV thin film solar cell are crucial when trying to achieve optimal performance for a good price. The discovery of the photoelectric effect and the concept of photons sparked interest of finding more ways to create efficient PV cells. The decisions on what materials to use in PV cells have paved the way for new developments and increased efficiency. When the first thin film solar cell was created it was around 1% efficient and with todayââ¬â¢s innovations and engineering decisions efficiencies are now able to achieve up to 20. %. If this trend to improvement continues the way it has been over the past 40 years then the technology may pave the way for complete solar power generations . References: 1.

Discrimination and Racism in America Essay Example | Topics and Well Written Essays - 1000 words
Discrimination and Racism in America - Essay Example One of the most popular theoretical explanations of discrimination is social differences existed in society and class struggle theory (antagonism), conflict theory and subcultural theory. The social conflict and class struggle theories states that society is based on social antagonism of two main social groups, men and women, workers and capitalists, blacks and whites (Wang 75). There is a smaller group who own and control the means, now chiefly machines, factories, and offices, that are used in the production of these goods. Also, disadvantageous groups in society often have an interest in change, and equal rights with minority. One of the most interested theories was proposed by Nathan Glazer (cited Wachtel 56). He argues that it has developed as a nation of minorities, each of which is accepted as a social entity but none of which has been accorded legal status or recognition. The popular picture of the country as composed of a large and monolithic majority, which tolerates some a nd opposes other minorities is therefore false. One of the main social condition which supports discrimination is social and class differences resulted in different education opportunities and different professional skills. The extensive number of charges of discrimination that continue to be filed by members of minority groups and women also argues strongly against assertion that affirmative-action programs are being implemented and that there is discrimination in education. The problem is that social location limits education opportunities from school and college years (Wang 30, 143) For this reason, many people belonging to low social classes (a lot of black people and minorities) lack knowledge and skills to enter the University or obtain a high-paid job. This condition is closely connected with historical development of the nation and high poverty rates among racial minorities and black population (Moses 121). Also, social roles of women as mother and wives limit their professional opportunities and career development. The case of women is different in many factual respects, but the principle is the same. Unfortunately, there is much fictitious "history" used to apply the "minority" concept to women. In the case of women, as in the case of minorities, their achievements were also made to look like the government's gift. Another social problem is that disadvantaged groups are defined by their color (black) or by their sex (female), although other groups are also shown to be underrepresented on the statistical graphs that correlate population quotas with achievements (Wang 43). Social and regional separation of disadvantageous groups is another social cause of discrimination. Many racial minorities, gay and lesbian people live as a separate community or neighborhood. Racism can be and must be eliminated in American society by changing personal values and national beliefs about minority groups and their social value. In a democratic society, "some seek to change the laws so that those who have been at a social and economic disadvantage may enjoy an enforceably favored status" (Wachtel 65). The problem is that affirmative action programs worsen the status and image of

Motivation. What Is The Best Way To Motivate Employees Research Paper
Motivation. What Is The Best Way To Motivate Employees - Research Paper Example Motivation is considered a key factor in increasing efficiency in business. As a result, motivated employees will exert their dynamism to accomplish their purposes and goals. According to Sultan, Sarwat he said,â⬠for an employee to be motivated, he or she perceived that their wants are being met. Thus, the satisfaction of the employee represents an indispensable dimension of the motivational process (Sarwat, 2013); a satisfied individual would certainly contribute positively to the realization of organizational goals and objectives. A dissatisfied employee may not only contribute but can even act in such a way that the realization of such goals and objectives could be completely destroyed, this underlines the importance of employeesââ¬â¢ satisfaction to the organizationâ⬠(Anka, 1988). Lack of motivation will cause numerous problems such as; reducing the annual income, exit of the organization if given the opportunity, produce low quality work, and unsatisfying results o f any productions. This causes work to become a stressful place, and it may transform into a nightmare. For instance, according to Rebecca Maxon (1999), ââ¬Å"Three out of every four American workers describe their work as stressful and the problem is not limited to these shores, in fact, occupational stress has been defined as a global epidemic by the United Nations' International Labor Organization, while the physical effects of this epidemic are often emphasized; the economic consequences also are alarming. Workplace stress costs U.S. employers an estimated $200 billion per year in absenteeism, lower productivity, staff turnover, workers' compensation, medical insurance and other stress-related expenses, considering this, stress management may be business's most important challenge of the 21st centuryâ⬠. Therefore, the environment of any workplace does matter for increasing production and limiting its costs, managers are the tools to help improve their employeesââ¬â¢ per formance. Although, a lot of business analysts disagree with each other on determining the best method to motivate employees, from offering promotions to working less hours, I firmly believe that if managers provide a clean and safe environment for their employees within the consideration of welfare, thoughts, and appreciations of their hard work, and offer high wages they will create a productive, functional, successful workplace for each other.à To emphasis how clean and safe environments are relevant in motivating employees at their workplace, a lot of companies have started to renew their policies. These policies focused on what exactly they can develop to build a sociable, truthful, creative, and friendly atmosphere for their workers. Also, the courtesy of spending more money on their facilities to be more presentable and eligible enough to remain a satisfying place for their workers could be beneficial. Therefore, employees are seeking these modifications badly so they can be more inspired and enthusiastic about their jobs, consequently, managers and supervisors are responsible for building a clean and safe environment for their workers. The consequences of ignoring this key factor will lead employees to be unwilling to produce more for the business, which will create critical problems between them and their managers. This leads to an unsatisfied workplace environment that could exaggerate employeesââ¬â¢ attitudes about leaving their jobs. According to Kori Rodleyââ¬â¢s (2010) article about how important the work environment is to employee turn-over, she said ââ¬Å"When employees expect a certain type of environment and get something very different, problems can result, those

My philosophy of education Essay Example | Topics and Well Written Essays - 500 words
My philosophy of education - Essay Example During an observation at Battery Park City School, I found an example. In a class of first graders, when a girl was moving a bean bag chair by herself, a boy classmate walked up to her and helped her move it. As soon as Liz, who is their teacher, saw it, she said, ââ¬Å"Oh! Look at him. How gentle he is! You are a gentleman.â⬠In this case, the boy is recognized and feels a sense of pride with what he has done. This helps the boy learn that helping others is a good thing. The teacherââ¬â¢s words are helpful not only for the boy, but also for the rest of students in class. Hearing their teacher praise their classmate for lending a helping hand will help them realize that helping others is a good thing. Through a few words of praise, students could learn what is right and it helps form their personality. In this context, praise is an effective learning method and teaching method. Alice S. Honig discussed the positive solutions to address typical difficulties. One of the positive solutions mentioned was praise. According to Honig, ââ¬Å"Children who are tense may show signs of pressure and frustration, like biting their nails or stuttering. Harsh response will only make children more tense. Instead, find situations in which these children shine, and bolster their self-confidence with Praise. For example, ââ¬ËMarques, you did a beautiful job of hanging up your coat!ââ¬â¢ â⬠. For Gartrell as cited in Meece and Soderman, appropriate praise is one that is ââ¬Å"sincere, constructive, and encouragingâ⬠. Children tend to flourish when adults take notice and recognize a childââ¬â¢s effort and accomplishments. Recognizing positive changes in a childââ¬â¢s behavior and abilities also helps. Pro-social behavior is developed when the positive results of a childââ¬â¢s behavior on another is pointed out. In promoting a positive verbal environment, praise is used as a means to encourage a childââ¬â¢s intrinsic motivation. As the articles
