An Un-PAINE-ful Appeal essays
An Un-PAINE-ful Appeal essays Thomas Paine was more than just a journalist. Thrown in prison on more than one occasion because of his passionate and controversial writing, Paine was one of the preeminent writers on infant Americas fight for freedom at the end of the 18th century. Best known for Common Sense, published in 1776, Paine also wrote The Rights of Man that, when censored by the government, simply increased its popularity. In The Rights of Man, Paine takes a humanistic approach, believing strongly in the power and goodwill of man to overcome its problems and chastises governments that interfere with the natural order of society. Paines primary ethical appeal is to appear sensible and benevolent by using clear, unsophisticated diction and a cool, relaxed style of writing. Instead of using intense, fervent phrases, Paine relies on concise, defined wording and a style of writing that entices the writer to take his side of the argument. It is after all quite difficult to rebuff the notion that our own society is more Paines sensibility is plainly evident in the first paragraph where he opens with a thoughtful, clearly stated sentence and continues to his thesis, a short sentence that contains all he needs to set up his argument in the essay. Paine wastes little time in getting to the point and rarely strays from that style. The opening sentence, Great part of that order which reigns among mankind is not the effect of government, (Paine, 393) unobtrusively states Paines argument and contains no unnecessary words that some writers like Edmund Burke often use for no apparent purpose. The essay takes on a logical feel to it because Paine does not seem to let his disagreement with Burke overshadow his goals in the essay. In addition, Paine abandoned the first-person style that many of his contemporaries favored for a third-person style that makes him seem more humble and gives him credibilit ...

Fun Ideas for Last Day of School Activities
Fun Ideas for Last Day of School Activities On the last day of school, the kids have mentally checked out, the teachers arent far behind, and theres no more time for long-term projects. But, we still need to fill the day with something productive in order to keep the natives from getting ridiculously restless and out of line. If youre wondering how to organize the last day of the school year so that its as fun and memorable as possible, consider these ideas. Write a Letter to Next Years Students Ask your students to write a letter to the students you will teach next year. The kids can offer tips for success in your classroom, favorite memories, inside jokes, anything that a new student in your room might need or want to know. Youll get a kick out of seeing what the kids remember and how they perceive you and your classroom. And you have a ready-made activity for the first day of school next year. Make a Memory Bookà Design a simple little book for the kids to fill out on the last day(s) of school. Include sections for my favorite memory, a self-portrait, autographs, what I learned, a drawing of the classroom, etc. Get creative and your students will appreciate a memory book of their year in your room. Clean, Clean, Clean Use the power of youthful energy and elbow grease to lessen theà load you face in closing down and cleaning up your classroom. Kids will love to scrub desks, take down posters, straighten up books, whatever you ask them to do. Write all of the tasks on index cards, pass them out, turn up the music, and supervise. A cute idea is to play The Coasters Yakety Yak while they clean. It sings, Take out the papers and the trash, or you dont get no spending cash! Dare them to finish their jobs before the song is over. Assign Impromptu Speeches Think of 20 quick speech topics and have the kids choose them from a jar. Give them just a few minutes to prepare mentally and then call them up for spur-of-the-moment speeches. Fun topics include Convince us to buy the shirt you are wearing now or How would the school be different if you were principal? Click here for a complete list of topics. The audience loves to watch and the speakers will love getting creative in front of the class. Play Outdoor Games Dust off that outdoor games book that you never had time to use this year and pick a few activities for the last day of school. A great choice is Guy Baileys The Ultimate Playground and Recess Game Book. The kids will be antsy anyways so you might as well put their energy and excitement to good use. Organize Learning Game Centersà The children wont even realize theyre learning. Pool together all of the educational games in your classroom. Split the class into small groups and designate centers in the room for each game. Set the timer and give each group a certain amount of time with each game. Give the signal and then the groups rotate around the room so everyone gets a chance to play all of the games. Focus on Next Year Give the kids time to write, draw, or discuss how things will be different in the next grade level. For example, third graders will love to imagine what they will learn, look like, act like, and feel like when they are finally in the world of fourth grade. Its only a year but to them, it seems a universe away. Hold a Spelling Bee Hold a traditional Spelling Bee using all of the spelling words from the whole school year. This one can take quite a while, but its certainly educational. Go Back to Back Use a safety pin to attach a large index card or thicker piece of paper to each childs back. Then, the kids go around and write nice comments and memories on each others backs. When youre all done, each child gets to keep his or her note with compliments and fun times written on it. Teachers, you can jump in, too. You just might have to bend down so that they can reach your back. Write Thank You Notes Teach your children to recognize and appreciate those individuals who helped make them successful this school year - the principal, secretary, food service workers, librarian, parent volunteers, even the teacher next door. This may be a good project to start a few days before the last day of school so that you can really do it right. Edited By: Janelle Cox.

Legal Case Study Essay Example | Topics and Well Written Essays - 500 words
Legal Case Study - Essay Example Generally, death in any manner is a sad thing for the kith and kin of the deceased or dying. Euthanasia or assisted death though relatively new has caused much debate. But Terriââ¬â¢s case of a person who can not decide whether she wants to continue in a persistent vegetative state. She could not decide or communicate her desire. Hence many ethical issues arose. The personal ethics of her parents and husband were in sharp contrast in the later part of Terrisââ¬â¢ life. Michael her husband wanted her artificial life support to be withdrawn and the Schindlers, Terriââ¬â¢s parents did not. They argued it would have been against the wishes of Terri who they claimed to be a devout catholic. The parents were wrong in persisting in their demand even after the courts ruled in favour of Michael and appointed him guardian. The judiciary acted reasonably in the matter. Bouma (2005) opines that ââ¬Å"There are adequate checks and balances in the levels of judicial system, and courts have not acted precipitously or hastily.â⬠Yet the Florida Legislature passed a bill authorizing the governor to intervene in Terriââ¬â¢s case. The law was later struck down by the Supreme Court yet the legislature and executive tried unsuccessfully to decide the fate of a person who can not think for herself, against her implied wish as the courts had decided. The society violated its ethics in that special interest groups tried to influence and decide such a highly personal question of a caretakerââ¬â¢s decision about life support to a person in a persistent vegetative state. Lastly, the government violated its duty towards the larger majority of people needing medical aid which would have been provided for instead of spending the amount in costly healthcare of an individual whose legal guardian had expressed his desire to stop her artificial life

Project Paper Part C Statistics Example | Topics and Well Written Essays - 2250 words
Paper Part C - Statistics Project Example Similar to the coefficient of variation, the coefficient of determination normally ranges between +1 and -1. The coefficient of determination between the credit balance and size is established at 0.566; this means that 56% of the total variation can be explained by the linear relationship that exists between the credit balance and size of the household. The remaining 44% of the variation cannot be explained by the linear relationship which exists between the credit balance and size of a household. The above results of a two tailed t-test help a statistician to understand the probability of the differences of a given data; it indicates whether data are attributed to sampling errors. The t-test is mostly used by statisticians to reject a particular hypothesis or not. Mostly, if the p-value, which indicates the level of probability, is less than a certain significance level, one can reject a hypothesis. The above two tailed t-test was performed on credit card balance (variable 1) and size of household (variable 2). The P (T

Higher Dimensional Black Hole Corrected Tunneling Radiation
Higher Dimensional Black Hole Corrected Tunneling Radiation Corrected tunneling radiation of a higher dimensional black hole and generalized second law S. S. Mortazavi[*]1, A. Farmany1, H. Noorizadeh2, V. Fayaz1, H. Hosseinkhani1 Abstract Study the quantum gravitational effects on a higher dimensional horizon, the semiclassical s-wave tunneling radiation of black holes are calculated. It is shown that quantum gravitational effects correct the semiclassical radiation of the horizon space time. Within this background, the generalized second law of thermodynamics is applied to the black hole entropy. 1. Introduction It is interesting that that radiation of black holes can be viewed as simple tunneling phenomena. In this view, a particle-antiparticle pair may form close to a black hole event horizon. The ingoing mode is trapped inside the horizon while the outgoing mode can tunnel through the event horizon. It is interesting that this effect is a quantum mechanically and the present of an event horizon is essential (Hawking, 1975). Recently, the semiclassical analysis of this phenomenon carried out by Parikh and Wilczek (Parikh, Wilczek, 2000; Parikh, 2002; Parikh, 2004; Parikh, 2004). Parikh-Wilczek proposal of black hole tunneling radiation is based on the computation of incoming part of action for classically forbidden of s-wave emission across the horizon (Parikh, Wilczek, 2000; Parikh, 2002; Parikh, 2004; Parikh, 2004; Kraus, Wilczek, 1994; Kraus, Wilczek, 1995; Kraus, Wilczek, 1995; Kraus, Keski-Vakkuri, 1997; Berezin, Boyarsky, Neronov, 1999; Volovik, 1999;1999; Calogeracos, Volovik,1999). As a comparison between Hawking original calculation and tunneling method, it is easy to see that the hawking method is a direct method but its complication to generalization to all other space times is failed while the Parikh-Wilczeck proposal, the tunneling approaches have been successfully applied to a wide range of both the black hole space time horizon and cosmological horizon. For example, 3- dimensional BTZ black holes (Agheben, Nadalini, Vanzo, Zerbini, 2005; Wu, Jiang, 2006), Vaidya space time(Ren, Zhang, Zhao, 2006), dynamical black holes(Di Criscienzo, Nadalini, Vanzo, Zerbini, Zoccatelli, 2007), black rings(Zhao, 2006), Kerr and Kerr-Newman black holes(Jiang, Wu, Cai, 2006; Zhang, Zhao, 2006; Hu, Zhang, Zhao, 2006; Kerner, Mann, 2006), Taub-NUT space time(Kerner, Mann, 2006), Gà ¶del space time (Kerner, Mann, 2007), dynamical horizons(Di Criscienzo, Nadalini, Vanzo, Zerbini, Zoccatelli, 2007), cosmological horizons(Parikh, 2002; Medved,2002; Sekiwa, 2008), Rindler spac e time (Medved, 2002), de Sitter space time. Of course in all of these approaches the Unruh temperature is recovered successfully (Unruh, 1976; Akhmedova, Pilling, Gill, Singleton, 2008; Banerjee, Kulkarni, 2008; Banerjee, Majhi, 2008). This model is applied to not only the black hole event horizon, but also to the cosmological horizon (Parikh, 2002; Medved, 2002; Sekiwa, 2008). The black hole tunneling method was studied in different space-times and different frames and the time contribution to the black hole radiation is developed in (Chowdhury, 2008; Akhmedov, Akhmedova, Pilling, Singleton, 2007; Zhang, Cai, Zhan, 2009; Banerjee, Majhi, 2009; Akhmedov, et al, 2006; Akhmedov, Pilling, Singleton, 2008). In continue, the spectrum form of the tunneling mechanism is analyzed using the density matrix technique (Banerjee, Majhi, 2009). However the Parikh-Wilczek method is based on the classical analysis, when it comes into the high-energy regime, for example a small black hole whose size can be compared with Planck scale, the effect of quantum gravity should not be forbidden. In this case, the conventional semiclassical approaches are not proper and the complete quantum gravity analysis is required. To study the quantum gravitational effects on the tunneling mechanism it is interesting to relate the analysis under a minimal length quantum gravity scale ( Adler, Chen, Santiago, 2001; Han, Li, Ling, 2008; Farmany, et al, 2008; Shu, Shen, 2008; Wang, Gui, Ma, 2008; Setare, 2004; Kim, Park, 2007; Nouicer, 2007; Zhao, Zhang, 2006; Xiang, 2006; Dehghani, Farmany, 2009). In this paper, the black hole tunneling radiation is studied based on the generalized uncertainty principle. It is shown that the generalized second law of thermodynamics applie a bound on the tunneling radiation. 2. The corrected Bekenstein-Hawking entropy A d-dimensional spherical symmetric black hole background is defined by (1) where . The uncertainty in the position of a particle, during the emission, (2) where applying the uncertainty principle, we obtain the energy of radiated particle, (3) Where and Mpl is Planck mass. Temperature of black hole in a d-dimension space time may be obtained by setting the radiated particle mass m to. The d-dimensional black hole temperature may be obtained as, (4) where d3. Eqs. (4) shows the temperature of a d-dimensional black hole with . The Bekenstein-Hawking entropy is usually derived from the Hawking temperature. The entropy S may be found from the well known thermodynamics relation, (5) From (3-5) we obtain, (6) Quantum gravitational effects of horizon may affect on the thermodynamics of black hole and modifies its usual thermodynamical behavior. Study of black hole thermodynamics in the quantum gravity theory was made using a generalized uncertainty principle (Adler, 1999; Hossenfelder et al, 2004; Maggiore, 1994; Kempf, Managano, 1997; Farmany, Abbasi, Naghipour, 2007) (7) Where lpl is the Planck length. Setting 2rh as , we obtain, (8) Solving for minimum and expanding around lpl2=0, eq. (8) reads, (9) Comparing (9) with (7) we obtain, (10) inserting (4) into (10), the d-dimensional black hole temperature me be obtained, (11) The corrected entropy Sââ¬â¢ may be obtained from the thermodynamics relation (5), (12) 3. The corrected black hole radiation As shown by Parick and Wilczek (2000) the WKB approximation relate the tunneling probability to the imaginary part of the action (13) Where I is the classical action of trajectory. The difference between all approaches of tunneling method is in how the action is calculated. As shown by Arzano et al (Arzano, Medved, Vagenas, 2005), (14) in terms of black hole mass M and energy E, which is correspond to (15) provided the Bekenstein-Hawking entropy/area relation. Consider the above relation, eq.(13) can be written in the following general form, (16) The quantum gravity-corrected black hole entropy is given by eq.(12), so, (17) Substituting (17) into (16) we obtain, (18) which shows the corrected tunneling probability and . 4. Generalized second law of thermodynamics and modified black hole tunneling radiation Bekenstein (1981) has conjectured that the entropy S and energy E of any thermodynamic system must obey, (19) where R is defined as the circumferential radius. This bound is universal in the sense that it is supposed to hold in any matter system. The Bekenstein bound has been confirmed in wide classes of systems. However, as pointed by Bekenstein, the bound is valid for systems with finite size and limited self-gravity. Counterexamples can be easily found in systems undergoing gravitational collapse (Bousso, 1999). Another entropy bound is related to the holographic principle, which says that the entropy in a spherical volume satisfies (20) where A is the area of the system. It was shown that this bound is violated for sufficiently large volumes (Fischler and Susskind, 1998). As shown by eqs.(19-20), there is a bound on the entropy of the black hole when it related to the black hole area. While the black hole entropy bound applied to eq. (7), we obtain, (21) So, in the presence of entropy bound, eq. (16) may be, (22) Combining eq.(22) and (18) we obtain the corrected tunneling probability of black hole radiation. (23) Conclusion The semiclassical black hole tunneling radiation is calculated by the Parikh-Wilczek tunneling proposal of black hole radiation based on the generalized uncertainty principle. It is shown that the Bekenstein-Hawking entropy of black holes receives a correction that affects on the radiation tunneling probability. In continue applying the generalized second law of thermodynamics to the modified black hole tunneling radiation is obtained. References Agheben, M., M. Nadalini, L. Vanzo, S.

painting: the lost art? :: essays research papers
Painting: The Lost Art? I feel very strongly that there is an indifference to painting in todayââ¬â¢s society. In todayââ¬â¢s technology age, a high value is not placed on aesthetics such as painting. American society is drawn more to television programs and sporting events than to operas and art galleries. Very few paintings or other works of art would garner massive publicity in todayââ¬â¢s society. The artwork would have to stimulate the mind in a negative way to receive any attention at all. It would have to spark a major controversy by being vulgar or politically incorrect in some other way to spark conversation about it. American society, in particular, is drawn to conflict as opposed to appreciating a work of art for its aesthetic brilliance. Painting is nearly dead in toadyââ¬â¢s society. Most people view only music as an art form and place a high value on it. Painting is left to only school projects or murals on abandoned buildings. It is often overlooked and under appreciated. Painting cannot be appreciated by mainstream America because we are not educated on all of its intricacies. Public knowledge of painting and art as a whole is dismally low, and there is an indifference to painting mainly because people donââ¬â¢t understand it. Many people donââ¬â¢t know what to look at, or what to look for when observing a painting, and therefore cover up their lack of knowledge by overlooking painting as an art form. Many American critics of todayââ¬â¢s society would not have been able to appreciate Manetââ¬â¢s Luncheon on the Grass or Monetââ¬â¢s Impression Sunrise, because of its impressionist style. It would be viewed as ââ¬Å"uglyâ⬠or ââ¬Å"unattractiveâ⬠because so many fine details were left off. People of todayââ¬â¢s society would not take the time to sit down and try to interpret the art that Monet was trying to display on the canvas. Americans of today want everything handed to them and would not have wanted to pick their brain to try to figure out exactly what Monet was trying convey to us as the viewer. Many Americans probably wouldnââ¬â¢t want so many of the details of Impressionism left off. They would want to look at it, interpret it at face value and leave it alone. They wouldnââ¬â¢t take the time to ââ¬Å"read between the linesâ⬠of the painting, looking for hidden meanings and intricate details. I feel very strongly that in todayââ¬â¢s society, painting has taken a backseat to the Internet and rock concerts.
