The Law of Conservation of Energy Defined

The Law of Conservation of Energy Defined The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference. In classical mechanics, conservation of mass and conversation of energy are considered to be two separate laws. However, in special relativity, matter may be converted into energy and vice versa, according to the famous equation E mc2. Thus, its more appropriate to say mass-energy is conserved. Example of Conservation of Energy If a stick of dynamite explodes, for example, the chemical energy contained within the dynamite changes into kinetic energy, heat, and light. If all this energy is added together, it will equal the starting chemical energy value. Consequence of Conservation of Energy One interesting consequence of the law of conservation of energy is that it means perpetual motion machines of the first kind are not possible. In other words, a system must have an external power supply to continuously deliver unlimited energy to its surroundings. Its also worth noting that its not always possible to define conservation of energy because not all systems have time translation symmetry. For example, conservation of energy may not be defined for time crystals or for curved space times.

Aggregates and Social Aggregates in Sociology

Aggregates and Social Aggregates in Sociology Within sociology, there are two kinds of aggregates that are commonly used: the social aggregate and aggregate data. The first is simply a collection of people who happen to be in the same place at the same time, and the second refers to when we use summary statistics like averages to show something about a population or a social trend. The Social Aggregate A social aggregate is a collection of people who are in the same place at the same time, but who otherwise do not necessarily have anything in common, and who may not interact with each other. A social aggregate is different from a social group, which refers to two or more people who interact regularly and who have things in common, like a romantic couple, a family, friends, classmates, or coworkers, among others. A social aggregate is also different from a social category, which refers to a group of people defined by a shared social characteristic, like gender, race, ethnicity, nationality, age, class, etc. Every day we become part of social aggregates, like when we walk down a crowded sidewalk, eat in a restaurant, ride public transit with other passengers, and shop in stores. The only thing that binds them together is physical proximity. Social aggregates sometimes figure into sociology when researchers use a convenience sample to carry out a research project. They are also present in the work of sociologists who conduct participant observation or ethnographic research. For example, a researcher studying what happens in a particular retail setting might take note of the customers present, and document their demographic makeup by age, race, class, gender, etc., in order to provide a description of the social aggregate that shops at that store. Using Aggregate Data The more common form of an aggregate in sociology is aggregate data. This refers to when social scientists use summary statistics to describe a group or a social trend. The most common type of aggregate data is an average (mean, median, and mode), which allows us to understand something about a group, rather than considering data that represents specific individuals. Median household income is among the most commonly used forms of aggregate data within the social sciences. This figure represents the household income that sits exactly in the middle of the household income spectrum. Social scientists often look at changes in median household income over time in order to see long-term economic trends at the household level. We also use aggregate data to examine differences among groups, like the change over time in median household income, depending on ones  level of education. Looking at an aggregate data trend like this, we see that the economic value of a college degree relative to a high school degree is much greater today than it was in the 1960s. Another common use of aggregate data in social sciences is tracking income by gender and race. Most readers are probably familiar with the concept of the wage gap, which refers to the historical fact that women on average earn less than men and that people of color in the U.S. earn less than white people. This type of research is produced using aggregate data that shows averages of hourly, weekly, and annual earnings by race and gender, and it proves that despite legalized equality, interpersonal discrimination on the basis of gender and race still works to create an unequal society.

Changes in Social Lending Essay Example | Topics and Well Written Essays - 250 words

Changes in Social Lending - Essay Example dit permits very underprivileged people to insert themselves into projects that are focused on self-employment— with a view of generating some income. Yunus provides loans through his controversial bank, Grameen Bank—which makes him a pioneering single leader. Grameen Bank based in Bangladesh lends money through solitary groups. The bank’s approaches targets solitary groups as its prime building block. Further, the use of this technique has clearly had a significantly positive effect upon many prospective borrowers. Without Grameen, the financially handicapped wouldn’t have dared borrowing at all. I mean, to many of them, borrowing would figuratively be building castles in the air. Be that as it may, the determination to warranty that all members of solidarity groups are equally poor is inconsistent, and may not always improve the group performance at all. In all, microcredit is mere bunkum—in fact; it won’t succeed without the help of immense grants. In all, this is a reality that dents on the development of this approach. Conversely, this approach lacks clear lucidity. Glancing at it through perspectives, the overall effect of this development approach has not been to reduce poverty, but only to produce a debt gridlock for gullible borrowers—who are incredulously subjected to particularly supercilious rates of interests practical to conventional banks . It is no surprise at all that Yunus used the infused poverty in his country profitably to gain international attention. This approach of bottom of the pyramid has no capability of finally leading to long-term development, because many poor people will feel that they are being defrauded through the obviously feasible

Engaging parents and fathers in their children's early learning Essay

Engaging parents and fathers in their children's early learning - Essay Example For instance, the ministries and departments of education and child welfare have been in the forefront of funding projects that gather, assess, and analyze existing knowledge and best practices that would encourage other educational and learning stakeholders to work with and involve parents in young children’s learning (Desforges, 2003). This paper explores the subject of involving parents, more so fathers in children’s early learning. Many educationists concur that the importance of parental involvement in children’s early learning cannot be overemphasized. The first reason for this assertion is that parents are children’s first and most enduring educators. Thus, by working together with other child welfare and development practitioners, parents play a rather critical role in and have a positive impact on their children’s early learning and development. This positive impact of parental involvement stems from the fact that the time and activities shared among parents and children not only affect the children’s social and intellectual development but also their emotional development (Desforges, 2003). It is therefore imperative that parents understand that children’s early learning requires more than just being parents but requires them to take an active role in the children’s early learning. There are several parental factors infringing on or affecting a children’s early learning. These factors include parents’ socioeconomic status, education level and living conditions, which have direct bearing on a child’s early learning activities and outcomes. Nonetheless, more important than the above factors is the quality of a child’s home learning environment. Although parents may not have achieved a lot educationally and might be living in disadvantaged environment and circumstance, their regular engagement in their children’s early learning activities has

Literature in No Drama Essays -- Literary Analysis

By nature, Japanese No drama draw much of their inspiration and influence from the classics. Many are based on episodes from the most popular classics, like Atsumori, based on the Tale of Heike, or Matsukaze, which was actually based on a collage of earlier work. Even within these episodes do we find references to yet more classic works of literature, from the oldest collections of poetry to adopted religious texts. That isn’t to say that No is without its own strokes of creativity—the entire performance is a unique adaptation, and the playwrights had to be both highly educated in the classics, yet geniuses at the creative aspect of weaving song/poetry, dance, religion and literature together into a heart-wrenching spectacle. It might be easier to behold the similarities between no plays than the differences. The basic plot changes little: there is a traveler or monk who encounters a restless ghost or ghosts whose restless souls must be put to rest. The religious implications here are major, and become a central theme of No. In both Atsumori and Matsukaze, the monk chants â€Å"Namu Amida Bu,† for the Pure Land sect of Buddhism, as well as recites verses from the Lotus Sutra. The commentary mentions that â€Å"†¦The monk invokes Amida for the spirits of the dead, although the dead are comforted more often with passes from the Lotus Sutra.† (p.41) Atsumori’s ghost, as character â€Å"youth,† and Rensho, a monk, both quote together: â€Å"If I at last become a Buddha/then all sentient beings who call my Name/in all the worlds, in the ten directions/will find welcome in Me, for I abandon none,† which is from the sutra known as Kammuryojukyo. The chorus expands o n this quote until the end of the scene, the song being the playwright’s own creati... ... have a friend.† (p.40) Matsukaze’s text refers to a great deal more older poetry than Atsumori, perhaps simply because it is more relevant and appropriate in the context of the story: Matsukaze is a love story, and there is a lot present in the classics about love. Another kokinshu poem found in Matsukaze: â€Å"From the pillow/from the foot fo the bed/love comes pursuing,† (p.202) for example. The examples of the samples of poetry, and allusions to other works of literature, are so numerous and some so subtle that they are countless in No drama. No could not exist without the classics that it constantly draws upon. This calls for a highly educated audience to enjoy the play in its entirety. However, for the medieval age, it was new and exciting to see these classics woven together in a stage performance, so gracefully and creatively by the playwrights of old.

People vs. Larry Flynt

After watching the film the people vs. Larry Flynt, it is clear that the major message is that all Americans have rights under the constitution. Although in some cases many Americans may not always agree with each other, it is their right and freedom to do so under the Bill of Rights. In particular the first amendment is a major focus of the film.Throughout the entire movie the Larry Flynt character (Woody Harrelson) defends the fact that he is an American, therefore like all other Americans he is protected by the bill of rights and is entitled, specifically, to freedom of speech and freedom of the press. The film is a good portrayal of how our society and government perceive things as right or wrong. One of the most notable parts of the film is where the Flynt character argues with activists saying, â€Å"Murder is illegal but if you take a picture of it you may get your name in a magazine or maybe win a Pullitzer Prize.He continues his argument by saying â€Å"sex is legal, but i f you take a picture of that act, you can go to jail. † The point the film makes relates directly to the text in chapter two under â€Å"institutional adaptation† which states that in order for the constitution to remain viable , it must be able to adapt to changing times and deal with matters the authors could hardly have anticipated (p. 33). The film points out many weaknesses and flaws in the way courts are operated in America.There is one part in the movie where Flynt’s lawyer Alan Isaacman (portrayed by Edward Norton) tries to present what he feels as evidence to the jury, the judge refuses to let him show the evidence (other pornographic magazines. ) Although it is completely legal for a judge to refuse evidence, it shows that a man who is entitled power can still be very biased towards their own ideas and beliefs. The film is a very accurate portrayal of the true events since the film is based in part on the U. S. Supreme Court case Hustler Magazine v.Falw ell. The United States Supreme Court held, in a unanimous 8-0 decision Justice Kennedy took no part in the consideration or decision of the case, that the First Amendment's free-speech guarantee prohibits awarding damages to public figures to compensate for emotional distress intentionally inflicted upon them. Thus, Hustler magazine's parody of Jerry Falwell was deemed to be within the law, because the Court found that reasonable people would not have interpreted the parody to contain factual claims, leading to a reversal f the jury verdict in favor of Falwell, who had previously been awarded $200,000 in damages by a lower court. The First Amendment is the recognition of the fundamental importance of the free flow of ideas and opinions on matters of public interest and concern. The freedom to speak one's mind is not only an aspect of individual liberty but also is essential to the common quest for truth and the vitality of society as a whole. The First Amendment envisions that the p olitical debate that takes place in a democracy will occasionally yield speech critical of public figures.The Court held that the First Amendment gives speakers immunity from sanction with respect to their speech concerning public figures unless their speech is both false and made with the knowledge of its falsehood or with reckless disregard for the truth of the statement. Although false statements lack inherent value, the breathing space that freedom of expression requires in order to flourish must tolerate occasional false statements, lest there be an intolerable effect on speech that does have constitutional value.Falwell argued that the Hustler parody advertisement in this case was so â€Å"outrageous† as to take it outside the scope of First Amendment protection. But â€Å"outrageous† is an inherently subjective term, susceptible to the personal taste of the jury empanelled to decide a case. Such a standard â€Å"runs afoul of our longstanding refusal to allow d amages to be awarded because the speech in question may have an adverse emotional impact on the audience†. So long as the speech at issue is not â€Å"obscene† and not subject to First Amendment protection, it should be subject to the actual-malice standard when it concerns public figures.Clearly, Falwell was a public figure for purposes of First Amendment law. Because the district court found in favor of Flynt on the libel charge, there was no dispute as to whether the parody could be understood as describing actual facts about Falwell or events in which he participated. Accordingly, because the parody did not make false statements that were implied to be true, it could not be the subject of damages under the New York Times actual-malice standard. The Court thus reversed the judgment of the Fourth Circuit.
