Thermal Energy Storage - Essay Example Appreciation for the advantages and benefits of the thermal energy systems has encouraged many people to use the technology to cut power costs and lessen the negative impact of non-renewable sources of energy on the environment. The low-cost and readily available materials that can serve as thermal energy storage media also inspired people more to develop and install it. Nevertheless, much has yet to be done in educating people, especially heavy consumers of electrical power, about the science and technology behind thermal energy storage. With this and their knowledge about its advantages, the optimization of the use of thermal energy through its effective storage will further persuade them to shift to renewable energy as the alternative to the diminishing and environmentally harmful energy sources, such as petroleum. Thermal energy, thermal energy storage, renewable sources of energy, solar energy, fossil fuels, law of thermodynamics, heaters, solar heating, kinetic energy, internal energy, thermal storage, thermal mass, storage media For a great number of years, mankind has been largely dependent on fossil fuels and other non-renewable sources of energy to power basic utilities. Since the 1800’s, the industries and the economies, in general, of many countries have been run by relying on petroleum. Consequently, the demand for this particular fossil fuel had increased tremendously in the following decades. Even by the latter years of the 20th century, however, problems have arisen due to the heavy reliance on petroleum. Although there were other means of producing energy introduced, these were very minimal compared to those powered by oil. Today, several countries have used nuclear power, coal-powered energy generation, and other non-renewable sources of energy such gas power as alternatives to petroleum. There are also countries that have developed renewable sources such as hydroelectric, geothermal, solar, and wind energies. However, these

Child Development Article Example | Topics and Well Written Essays - 750 words

Child Development - Article Example According to the research findings cognitive development involves the change in a child’s intelligence, language, thought skills, and patterns, a well as problem solving, while social emotional factors involve the relationship of the child with others, emotional changes, and personalities among others. Biological factors involve the change in a baby’s body such as the brain, weight, and height, which are based on genetic inheritance. The early years of a child are the most important. Generally, healthy development fosters child’s abilities; however, children tend to develop at their own pace, although their development should be closely monitored. From the infancy stage to three years, a child highly depends on his/her parents or caregivers; the child’s biological development is based on genetic inheritance. The brain development of a child enables it to crawl, eat, laugh, or speak; however, this development is based on the parent’s interaction with the child or the genetic inheritance. Genes are transferred form the parents to a child, and therefore, there are similarities between the child and his parents or relatives. This is evident in appearance, talents, and personalities developed as they grow. Each child must inherit gene from his parents, as infant development genetic characteristics are noticeable; for instance, their height, weight, hair color, or eye color may resemble their parents. The quick growth of a child may also be compared to his relatives’ genetics. ... For example, some children can construct a full sentence by the age of three, while others cannot. Cognitive Factors Cognitive factors mainly involve changes in a child’s intelligence, language, and thinking; children are capable of incorporating information into existing knowledge as they develop. An infant may learn how to explore the surrounding environment with his hands or eyes; from birth, infants begin their learning process. They gather, sort, and process information, and as a result, they are capable of understanding their world. In early childhood, a child’s intelligence develops such that their language and imagination mature. The infants begin to learn through focusing on an object, volume of sound, colors and so on. At three months, these infants are capable of imitating facial expressions such as, smiling or frowning. At six months, babies can recognize their parents and their names as well. By the age of three years, a child can begin to be independent by playing with different kind of instruments, without assistance. The child also understands simple words like than you, please and sorry, depending on the parent’s upbringing. When an infant is one year old, he is capable of making different sound such as bubbling. At three years, he can speak orderly words; this development results from learning from the infant’s caregivers. Cognitive development fosters curiosity, problem solving, memory, and attention in 1-3 year old infants. Their surroundings assist them in learning new skills. Parents contribute to cognitive development in numerous ways, expanding the attention time for their children, and therefore, the children are able to explore and learn. Parental listening skills are vital in this

The Influence of Mass Media in Society Research Paper

The Influence of Mass Media in Society - Research Paper Example The effect of television on the way that people perceive reality can be seen in its full clarity through the influence of reality shows in the daily loves of people. The Kardashians, The Beverly Hills Wives, Guiliana and Bill, these are all scripted programs that â€Å"depict† the â€Å"real life† of a celebrity in such a manner that what they are doing on-screen becomes gospel truth to the voyeuristic viewer. This paper will focus on how television, through reality shows, has managed to changed the way that people perceive the reality of their own lives. Using facts and other verifiable information from various websites, articles,books , and/or journals, this paper will do its best to explain the phenomenon of the reality show and how it manages to change the way people view how they should conduct their lives based upon the television images and â€Å"real life† situations that they see. Towards the end, this paper will make mention of â€Å"The Hunger Gamesâ €  and how that particular movie helps to depict the evils of reality shows and how people sometimes, can no longer tell the truth between fiction and real life because of what television shows them. In order to best explain the phenomenon that has been created by the reality shows, one must first understand what a reality show is and what comprises the format. It is important for people to know that to call a reality show â€Å"unscripted† is a fallacy. According to David Rupel of the Writer's Guild of America reality shows do not have scripts but there are writers who â€Å"create formats, cast people based on character traits and edit scenes to tell a powerful, intriguing tale† (â€Å"How Reality TV works†). There are actually two types of reality shows, it either has (1) very little structure like The Kardashians, which means that the producer needs to sift through days worth of footage in order to develop a story line that the viewers will find intriguin g and stick to watching. Or (2) it is a reality show that is heavy on the formatting side such as The Amazing Race wherein the situations are pre-determined and thus includes a sense of drama that is more engaging for the audience (Rupel, David â€Å"How Reality TV Works†). Because reality shows have nothing real happening within them, one cannot help but wonder as to how the producers of such shows manage to alter the perception of people about the reality of what they are watching and influence them into illiciting an emotion that connects them to the show. Rupel, gives us a perfect example of how television and reality shows manages to alter the viewers perception of reality. He explains: When I worked on Bug Juice(a show for Disney Channel about kids at summer camp), we faced a major problem with our big boy-girl love story. After weaving this storyline through nine episodes, we were caught flat-footed when our boy Connor had the nerve to dump his girl, Stephanie, off-cam era! We had enough interview bites to explain what happened, but we needed a good visual to make it work... If you catch a rerun of the show, you will see a happy Stephanie obliviously bounce up to Connor, who solemnly takes her hand and leads her off, as his interview bite explains he needs to end things. With the help of a tender music cue, it turned out to be a touching and bittersweet end to our summer romance. The reality: Steph walked up to Connor, gushed about his Adidas

Conviction on Economic Stability Essay Example for Free

Conviction on Economic Stability Essay One of the best renowned authors of the 21st Century, Adam Harmes – a foreign policy instructor bumped in an idea of analyzing the mishaps which is seemingly occurring in today’s era. Upon producing the book The Return of the State, he cited numerous instances and reasons why the International Business Propagandists must think of ways to expunge the ascending clash between the level of intervention implemented by the economic and political scheme, which he was able to sought as the primary problem on why the country has been departing from the reality of the immediate. Furthermore, he stated the major inevitable state of free-market trade mishaps are that by which denotes â€Å"supreme power† on America, which he, and Paul Martin believes as the root of all fault and that America should not only swallow the benefit out of the concept of trade alone, but rather share the Supremacy along with the other developing states since that as for the moment, they are considered as that which is vested with the pre-dominant influence over all the countries in UN and thus must make a move to improve the welfare of the general masses. He also mentioned numerous convictions on globalization’s effect in the economic realm, Unitarianism in America, G-20 series – as a cure to the rivalry in the economic basis and the expansion of the elite powers’ support over those who need such (Harmes). Concluding the totality of the book, Harmes’ enthusiasm and devotion on racial and international equilibrium and social welfare serves him a ticket on gaining the sympathy of those cosseting on prose historical books. In addition to that his arguments may have seemed opinionated in some certain circumstance, however, it illustrates the need of higher rationality and thus giving the â€Å"elites† in the world of globalization a tickle in their higher sense of rationality that the world is but a web of inter-related active countries and such voices and needs must be well taken care of (Harmes). The Return of the State is grandeur of Harmes in uplifting the banner of humanitarianism and concern for global economic stability. Reference: Harmes, Adam. The Return of the State.

The Learning Development Program Should be Retained :: Argumentative Persuasive Argument Essays

The Learning Development Program Should be Retained The local community college cancelled the Learning Development Program (L.D.C.) in the summer of 1999. This program was designed to assess and implement learning deficiencies in potential new students. The academic subjects covered were General Math, English and Reading. It had been determined in the late 1980s that a large number of incoming students were inadequately prepared in these subject areas, and were not able to enroll in the lowest level courses. Assessment test scores confirmed this observation. As a consequence, the college began a program graded on a pass-fail basis, designed to bring these students up to speed. The cancellation of this program should be reviewed, and some instructional alternative must be offered in its place. At this time, students are either rejected for admission, or admitted and then fail their English and math classes. The case for removing the L.D.C. classes rests on two issues: a lack of student interest and a lack of classroom space. Enrollment began to drop after 1997, when a new alignment of supervisory personnel occurred. Students were not made aware of the potential benefits to themselves, and were not prepared for the rigors of college-level work in such areas as English and math. The administration maintained that adequate alternatives were being offered. Further, it was argued that the economic factor of providing for instructors and instructional materials for the small numbers of students enrolled in L.D.C. classes did not make sense. One alternative available for failing students involves tutoring programs for English and math. These are "drop in" labs where those students struggling in the subject areas can come and receive help from a qualified faculty member. For many this service is all that is required. Yet, other students cannot succeed in the "drop in" labs, which often are noisy, and where individual attention is limited. The college can then request a special tutor. This would involve one-on-one instruction. The cost factor here, touted by the administration as of the utmost importance, spirals upward. It is difficult to understand this kind of budgeting, where another program containing indeterminate costs supplants one program that was successful in the past. The second issue concerns a lack of classroom space. A multi-use classroom was designated as the Academic Support Center in 1995-1997.

J.C. Penney Gift Certificate Concerns :: GCSE Business Marketing Coursework

J.C. Penney Gift Certificate Concerns J.C. Penney Company, Inc. has recently introduced a new point of sale (POS) system developed by NCR Corporation into their stores. In the first six months of operation, it has become apparent that there are unanticipated problems with the accounting and control functions pertaining to gift certificates. The new POS system does not provide for adequate tracking or control of the certificates on the sales floor, store level sales audit has inadequate procedures or data capture capabilities in place to track sales accurately and assign responsibility for missing certificates, and corporate accounting has no control over the gift certificate accounting on the store level and are constantly struggling to reconcile gift certificate information. Problems on the Sales Floor At the POS terminals on the sales floor, gift certificates are being stored underneath the cash register in a drawer with no security or control. The security and control of gift certificates has been overlooked during the drafting of the procedures for the new POS system. As a result, the security and control on gift certificates on the sales floor that had been in place with the old system has simply stopped. Employees are purely on the â€Å"honor† system. When sales associates ring up a gift certificate sale they have to key 1) the appropriate twelve-digit SKU from a list of 3 choices, and 2) a dollar value for the gift certificate shown on the face. For example, SKU #1 represented the $25 gift certificate, SKU#2 represented the $50 gift certificate, and SKU #3 represented the $100 gift certificate. After the sales transaction is complete, the sales associate must manually record the dollar value of the gift certificate on their cash audit report. During times of high volume, sometimes this final step is overlooked. Typically, the cashiers are just keying SKU #1 for any gift certificate sale and keying in the appropriate dollar value from the face of the gift certificate. The SKU’s are not electronically tied to a dollar value. This is a limitation of the previous POS system that was not addressed during the testing stage of the new system. Therefore, the error rate is very high and discrepancies in gift certificate sales are common. At the close of the shift, an electronic cashier report is generated on the register that just shows a total dollar amount tied to a SKU.
