The Effects Of Fracking On The American Public - 2044 Words

No matter what the government does to promote hydraulic fracturing, it is still going to be extremely unappealing to those knowledgeable on the topic. As Lisa Bracken states, â€Å"Crap is crap no matter what package you put it in† (GasLand). Hydraulic fracturing, or fracking, is the process of drilling about a mile into the shale below. Once the shale has been reached, water, sand, and a mixture of over 500 chemicals are injected into the Earth. When the pressure of the Earth hits a certain point, a portion of the injected water flows back up to the surface and the well begins to produce the valuable resource known as natural gas (McElroy and Lu 27). Fracking currently occupies thirty-four states and is quickly expanding. The government is†¦show more content†¦While the government states that fracking poses little threat to the environment, Wheeler is absolutely correct when stating that there is indeed a significant threat, as there is a copious amount of evidence t hat supports this. After viewing Fox’s documentary and reading various articles on fracking, there is no doubt that the quality of water and wildlife in the affected areas are at a serious risk. Wayne Smith, a farmer in Clearville, Pennsylvania, earned a large sum of money after leasing his 105-acre farm to a gas company for drilling, however, he now is regretting that decision. As a result of the drilling performed on his property, Smith realized that, â€Å"his livestock mysteriously dropped dead after having motor-skill breakdowns; a veterinarian said the deaths could be attributed to arsenic, high levels of which were found in water on Smith’s property† (Bateman 38). This threat to the wildlife has an overwhelming affect on those who rely on their livestock as their income. This lost income, as a result of fallen livestock, hits these families hard. Not only can they not drink their water, but they are also now faced with their families livelihood disappeari ng. Debbie May, a resident that Fox interviewed in his documentary, also experienced significant health problems with her animals. Fox describes the conditions of her cats by stating, â€Å"their hair was falling out† and

Minimum Wage For The State Of California - 2115 Words

At one point or another Americans have all had first jobs and those entry-level positions most always consist of entry-level pay. Meaning an employee cannot be legally paid a cent less than what is defined as minimum wage. Though every state has its own specific rate at which to pay its employees, some margins between states differ more than others. In the state of California the minimum wage is $10 per hour, for now that is. Government officials that take into account many factors regarding the health of the economy now and in the future determine this rate. For many people of the state that living wage is still not enough. So today the public has voted that the minimum wage should be increased to $15 an hour. Seeing the benefits early†¦show more content†¦Whether your arguments are for or against the rise in minimum wage there’s no way to perfect one rate that suits well with all of California. Example, the wage needed for a high cost area like San Francisco is goin g to be rather different than the wage a person would need in El Centro, which is highest in the state for unemployment (Perry 2). Say one uses a slightly different approach, that $15 an hour is good for a place like San Francisco because local wages can support itself if the economy were to go bad. That will not go off well if the same wage rate is in poverty stricken El Centro because of the lack of financial support. The rise in wage will negatively affect those in less fortunate communities. California being known for its forward thinking ideas, shall now become the state with the most damaging public policies put into place. A support of this argument lays out the main issue clearly, â€Å"When government artificially raises wages, it increases unemployment. Anyone should be able to understand that when labor costs are increase by government force, businesses often have no choice but to cut jobs if they are to remain profitable†(â€Å"Authors of California† 2).

The ironically cruel thing is that the ones that will be losing jobs were most likely the people completely for the wage increases. George Mason

Juvenile Delinquency Essay examples - 1465 Words

As stated by Bartol and Bartol â€Å"Juvenile delinquency is an imprecise, nebulous, social, clinical, and legal label for a wide variety of law- and norm-violating behavior† (2011, Pg 139). The juvenile delinquency term has come to imply disgrace in todays correctional institution. Our government is up hold to procedures and expected to come with a solution to solving the delinquent problem. An underage offender can be labeled a delinquent for breaking any number of laws, ranging from robbery to running away from home, and especially being involved in school violence. The following situations faced by correction officials when dealing with juvenile delinquents will be examined. Three main areas (child development, punishments, and deterrence†¦show more content†¦Children need to have a role model in their presence to advocate educational activities, community involvement, and avoiding contact with the law for bad behavior. As Baker states, â€Å"Delinquents are made , not born† (1991, Pg. 274). Possible noncriminal behaviors that may affect a juvenile to become delinquent include; child neglect and/ or abuse, termination of parental rights, foster home placements, those beyond parental control, interfamily assault and other criminal acts (Baker, 1991, Pg. 275). Parents must learn to teach family conflict intervention, management problems, favorable parental attitudes and involvement in problem behaviors. At an early age we learn to do what it thought, showed, and have the adult figure set the example in our lives. For example, helping with academic failure, avoid delinquent criminal peers, and guide away from drug use and crime. Adolescent problem behaviors start with the parents, then move into the community, and society must respond by providing alternative programs and institutions to help the problem. Moreover, punishment for juvenile delinquents may be the only resource available for correction officials. The juvenile justice system defines three categories of offenders: dependent, neglected, and delinquent.

A Memo to the President of the Big Private University Free Essays

Madam, the recent events that have brought our university within the media’s limelight may possibly give problems to the University, if no immediate action is taken. Allow me to outline the events and the possible NCAA infractions that our university may incur. The University is in the middle of an NCAA-imposed probation. We will write a custom essay sample on A Memo to the President of the Big Private University or any similar topic only for you Order Now As such, any additional infraction may seriously compromise the university’s status in the NCAA. The following incidents involving our male football team may lead to unwanted additional infractions: a total of 12 student-athletes had grade point averages ranging from 1.60 to 1.75; and Billy Joel, the team’s current quarterback, made an oral agreement on future possible plans with Whitney Houston, a sports agent. Allow me to expound on my point. The fact that five juniors, two sophomores, and five starters on defense have averages from 1.60 to 1.75 goes against the academic standards set my NCAA. The five starters, all of whom were freshmen last year, had averages lower than the NCAA set average of 1.8. The NCAA Backgrounder on Academic Reform clearly states the following: â€Å"Freshmen in college are required to complete 24 hours of course work and have at least a 1.8 grade-point average.† The low GPAs of the other student-athletes may also compromise another rule of the NCAA. The fact that these students have averages ranging from 1.60 to 1.75 may mean that they have failing marks which may greatly affect the completion of their degree requirements. Again, the said backgrounder is univocal: â€Å"Student-athletes entering college are required to complete 40 percent of their degree requirements by the end of their second year, 60 percent by the end of year three, and 80 percent by the end of year four.† I will personally look into this matter and investigate on the completion rates of the degree requirements of these concerned students. Nevertheless I think it is important for your good office to be aware of this potential problem. All in all, this lower than required grade point average of some of our student athletes undermines the NCAA’s set Academic Progress Rate (APR) of 925. Not complying with the APR will mean a contemporaneous penalty for the football team which, in plain language, refers to cuts in financial aids and scholarships granted to individuals in the team. Madam, it is also bothersome that the coaching staff hid these from the school administration. I cannot pinpoint who exactly in the coaching staff is culpable, but once NCAA Division I Committee on Infractions holds its own investigation, the university as an entity might not the only one to be given a sanction; individuals from the coaching staff (and other individuals from related departments) may also be held individually liable and as such, individual sanctions may be imposed against them. The last concern that I think should be brought up to your office is the fact that Billy Joel made an oral agreement with Whitney Houston, a sports agent, as he was threatened by the possibility that Marshall Mathers might take his place as quarterback. Again, NCAA is clear in its memo to directors of athletics dated October 6, 2006, that student athletes are not allowed to have a written or oral agreement with an agent who represents a sports agency. We must bear in mind that even if Joel’s agreement rests on the future possibility of Mathers replacing him, such an oral agreement on future plans is also not allowed: student athletes may not â€Å"agree to be represented by an agent in the future† (NCAA, â€Å"A Career in Professional Athletics: A Guide for Making the Transition,† 2004, p. 26). This also highlights the fact that Mr. Joel did not inform either his coach or his compliance coordinator regarding these matters. These are the NCAA-related concerns that I thought would be best to be brought up to your office. Thank you. References (2006-07).

The Theme of Society in Pride and Prejudice free essay sample

Originally written in the late 1700s, Jane Austen’s Pride and Prejudice satirically depicts the universal ideals in Old Regency England, primarily regarding social class. Austen follows the development of an outspoken middle-class British woman, Elizabeth Bennet, as she encounters and overcomes the many social barriers that separate her from her wealthy upper-class neighbors. Throughout the novel, Lizzie must confront society’s class-consciousness, particularly with her family’s growing relationship with the wellborn Bingleys and their friend, Mr.Darcy. It is clear that the author, Jane Austen, intended Pride and Prejudice to be a parody of the Old English society’s extreme emphasis on the social class structure and marriage that is not based on the heart but instead on convenience. Although our present-day social class system is more flexible than it was back then, members of the elite, especially celebrities, are still more apt to marry other upper-class citizens, rather than their social inferiors. For example, in today’s society it is the standard for rock stars, actors and models to pursue partners from a comparable social class. Similarly, a marriage between Fitzwilliam Darcy and Anne de Bourgh, daughter of the distinguished Lady Catherine de Bourgh, is expected because both parties are of equally notable lineage and hail from the same prestigious family. The union between the two aristocrats was planned â€Å"while in their cradles†, according to Lady Catherine de Bourgh, who makes a trip to Longbourn to see Elizabeth after hearing that she is engaged to Anne’s â€Å"future husband†.Lady Catherine is horrified that the anticipated matrimony may â€Å"be prevented by a young woman of inferior birth, of no importance in the world, and wholly unallied to the family† and makes every effort to prevent any chance of an engagement between Elizabeth and Darcy. During this confrontation, Lady de Bourgh’s behavior towards Elizabeth is quite a stonishing and completely supports society’s upper class prejudices and narrow-minded ignorant views towards the lower classes. If Lady de Bourgh had not had such stately ancestry, she may have lowered her social status with her ridiculous conduct.Lady Catherine’s ludicrousness is most likely taken from her haughty ego, which society has helped create by holding the upper class up on a pedestal. In Pride and Prejudice, Jane Austen speaks of a world where a person’s, more importantly a woman’s, reputation is a paramount obsession. A woman is made to believe to have to behave in certain ways; stepping outside the social normality makes her open to being banished from mainstream society. A prime example of this is when Lydia gets an invitation to visit and stay with the officers. Of course, Mrs.Bennet, the most obvious, oblivious, loud social conscious creature of Longbourn is all â€Å"happy go lucky† when she hears of Lydia’s call. Mr. Bennet who is the most stoic contradictory of Mrs. Bennet is even excited. However, when the news provoking invitation turns into a merciless elopement between Mr. Wickham and Lydia Bennet it sends shockwaves through the Bennet household. By becoming Wickham’s lover without being married, Lydia clearly places herself outside the social â€Å"norm†, and her disgrace threatens the entire Bennet family and their standing in society.The fact that Lydia’s terrible judgment would have condemned the other Bennet sisters to marriage less lives is a ridiculous but accurate tell of the stress put on the hierarchy that is Old English society. This theme also appears in the novel when Elizabeth walks to Netherfield and arrives with a muddy skirt, to the horror of the reputation-conscious Miss Bingley. At other points, the ill-mannered, ridiculous behavior of Mrs. Bennet gives her a bad reputation with the snobbish Darcys and Bingleys.Austen pokes gentle fun at the snobs in these examples, but when Lydia elopes with Wickham and lives with him out of wedlock, the author treats reputation and class as a very serious matter. Society is closely related to reputation, in that both have the strictly scrutinized way of life for the social classes of England. Even though the gap between the upper classmen Bingleys and the lower or middle classmen Bennets is as wide as the Amazon River, the Bennets may socialize with the Bingleys.However, they are obviously the lower level socialites and are treated as so. A prominent example of this discrimination was the Bingley sisters’ rude and disrespectful manner towards Elizabeth while she stayed at Pemberley to comfort Jane when she was overcoming her sickness. Austen again satirizes this kind of severe class-consciousness in the character of Mr. Collins, who spends most of his time sucking up to his upper-class patron Lady Catherine de Bourgh. Though Mr.Collins offers an extreme example, he is not the only one to hold such views. His view of the importance of class is shared by Mr. Darcy, who believes in the dignity of his roots; Miss Bingley, who dislikes anyone not as socially accepted as she is; and Wickham, who will do anything he can to get enough money to raise himself into a higher station. The satire directed at Mr. Collins is therefore also more subtly directed at the entire social hierarchy and the conception of all those within it, in complete disregard of other, more worthy virtues.Through the Darcy-Elizabeth and Bingley-Jane marriages, Austen shows the power of love and happiness can actually overcome class boundaries and prejudices, thereby showing that even if prejudices are hollow, unfeeling, and unproductive they can turn out to mean nothing to some people. Nonetheless, people similar to Miss Bingley as well as her friends are still trapped in the warped obsessive ladder that is the autocratic society that Jane Austen portrays throughout Pride and Prejudice.

Essay on How does Heat Transfer Works Example For Students

Essay on How does Heat Transfer Works I chose the topic of heat transfer because I find it really intriguing to learn about. I wanted to look further into how heat from two substances reacts with one another through another material that was placed between them. I will be looking at how to calculate the rate of heat transfer in a one dimensional space. This means that I will only be focusing on two temperatures, one hot and one cold, and a medium of which the heat will pass through. External factors such as other temperatures and time will not be used as they are for three dimensional spaces. Heat is a type of energy that transfers between two pieces of matter that have different temperatures. There are three ways heat can be transferred. The first way is through radiation and the second is convection. The third way is through conduction which is when an object or material conducts the heat from one substance through itself and to another. This is the method I will be focusing on. As stated in the second law of thermodynamics, heat flows from the matter or objects with the higher temperature to the one containing lower temperature and is not possible from cold to hot. This will continue until both objects have reached a thermal equilibrium. At this point, one object does not contain a higher temperature than the other, so the heat transfer ends. The rate at which the heat is transferred depends on the composition of the material that separates the two temperatures. For example, the rate at which heat flows from hot water to cold water through a copper cup will be different than if the cup is porcelain. The rate that the heat energy is transferred is directly proportionate to the rate at which the temperature changes. Also, since the lower temperature is gaining the same amount of heat that the higher temperature is losing, the graphs of these two should be negative reciprocals of each other. The higher temperature ‘A’ will generally have a negative slope whereas the lower temperature ‘B’ will have a positive slope. When both A and B have the same temperature, as mentioned before, they have reached a thermal equilibrium and therefore will have a slope of zero as neither one is gaining or losing heat. This chart represents the increase and decrease in temperature due to the loss and gain of heat. It does not represent any set data and is not a completely accurate diagram. The heat that the hot water loses is gained by the cold water. This continues until the hot water is the same temperature as the cold water. At this point, neither one is warmer nor colder than the other, so the transfer stops, resulting in a gradient of zero. To start off, I have two variables to work with. The first variable is the difference in temperature of the two objects; in this case, it is water. The second variable is the composition of the material that is separating the two different temperatures. I have considered this variable because it is directly involved with the heat transfer as the heat energy is passing from one object, through the material, and into the second object. As mentioned before, heat flows from the region with the higher temperature to the region with the lower temperature. Let G represent the rate at which the heat is transferred through conduction. This should be equivalent to the temperature gradient of dT/dx , where T(x) is the temperature and x is the distance travelled in the same direction and the heat is flowing. G=dT/dx However, with the current equation, there is no variable for the area of which the heat is transferring through. It only states that the gradient of dT/dx is the rate at which heat is transferred. It implies that the heat transfer between two substances will be the same if the area is 5cm2 and if it is 5km2. Area is another variable that affects the rate at which heat transfers. The larger the area of a medium, the more heat is transferred because there is more surface area that is conducting the heat from one substance and into another. An example of this is a large window in a building compared to a smaller one. Rooms with large windows tend to be colder because more heat has been lost from there. G=A dT/dx dT/dx is the temperature gradient in the direction which is normal to the area. This equation includes the area (A) of the surface that the heat is passing through, but it does not factor in the conductivity of the material placed between the two substances. Let the variable c represent the thermal conductivity of the material involved in the transfer. G=K A dT/dx In addition, the second law of thermodynamics states that heat energy must flow from a warmer region to a colder one. A negative sign must be placed on the right side of the above equation since the heat is being transferred in the direction of increasing x values will result in a positive quantity. .uf1eb2ee37c20adaa25ca0e0a2cce839a , .uf1eb2ee37c20adaa25ca0e0a2cce839a .postImageUrl , .uf1eb2ee37c20adaa25ca0e0a2cce839a .centered-text-area { min-height: 80px; position: relative; } .uf1eb2ee37c20adaa25ca0e0a2cce839a , .uf1eb2ee37c20adaa25ca0e0a2cce839a:hover , .uf1eb2ee37c20adaa25ca0e0a2cce839a:visited , .uf1eb2ee37c20adaa25ca0e0a2cce839a:active { border:0!important; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .clearfix:after { content: ""; display: table; clear: both; } .uf1eb2ee37c20adaa25ca0e0a2cce839a { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uf1eb2ee37c20adaa25ca0e0a2cce839a:active , .uf1eb2ee37c20adaa25ca0e0a2cce839a:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .centered-text-area { width: 100%; position: relative ; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uf1eb2ee37c20adaa25ca0e0a2cce839a:hover .ctaButton { background-color: #34495E!important; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .uf1eb2ee37c20adaa25ca0e0a2cce839a-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uf1eb2ee37c20adaa25ca0e0a2cce839a:after { content: ""; display: block; clear: both; } READ: Biology: The Thermodynamics of Protein-Protein Interactions EssayConduction heat flow ΔT/Δx is negative if the value of x increases while the temperature decreases G=-k A dT/dx The equation, G=-k A dT/dx , can be altered to form another equation.

The equation for thermal resistance is: R= L/Ak L stands for thickness A stands for area k stands for thermal conductivity G=ΔT/(L/Ak) G=Ak/L(T1-T2) These equations are measured in k/W which is equivalent to  °C/W. Using these equations, I can find the thermal resistance and the rate of heat transfer through a medium. Take for example, a large aluminum slate (k = 237 W/m K) of which the dimensions are 1 metre (m) in height, 0.5 metres (m) as the width, and a 0.5 centimetre (cm) thickness (depth) where the exterior temperature is 25 °C and the interior temperature is 30 °C.

One temperature starts off much warmer than the other. As the process of heat transfer commences, the hot temperature loses heat and gets cooler. At the same time, the cold temperature gains the lost heat and becomes warmer. When both have reached a thermal equilibrium, there is no more heat to transfer and both remain the same temperature. Heat transfer that takes place in a room is similar to the examples I have given, except that it occurs in three dimensional spaces. This means that other factors are required to make the equations work and come up with an appropriate answer. From these equations, other ones can be created to solve many other problems on heat transfer. Anywhere that temperature exists, there is some sort of heat transfer happening. By predicting, analysing, and testing any equation in thermodynamics, we can learn how to conserve heat and energy for when we actually do need it. Bibliography Kreith, Frank, and Mark S. Bohn.

Oliver Twist Essays - English-language Films,

Oliver Twist Charles Dickens, probably one of the most popular writer and humorist of his century was born at Landport in Portsea, on February seventh, 1812. His father, John Dickens was a clerk in a navy-pay office, and mother Elizabeth Borrow, along with his eight other siblings, which the other two died in infancy, lived in Portsea, and were fairly poor. Because of the arising poverty in his life time, Charles Dickens was forced to work as a child laborer when he was just twelve year of age. Although Charles Dickens faced many challenges in his young life, his love for writing dominated all of the challenges he faced in life. Perhaps, his book, Oliver Twist, was about, well, mainly about his life as a child. Although Dickens wrote Oliver Twist while he was finishing The Pickwick Papers and editing Bentley's Miscellany, he managed to make the novel remarkable for it's clarity of purpose and it's sustained intensity(The Cambridge guide to Literature in English; Ian Ousby). The story that lies behind the infamous story of a little orphan boy named Oliver is very different from his other previous novels. Other critics say that Oliver Twist is barely a novel, but more as a satire or sarcasm about the victorian era. First of all, the story begins with a young woman who gave birth to a boy whom they named Oliver. The young woman did not even have any time to hold her new born, but just in time to kiss him, then shortly died after that, the boy on the other hand survived, not knowing what kind of twist and turn his life would take as he grows and faces the real world. As the boy grew in a very vain and cruel environment, his turns in life was not going too good either. Having the parish not enough facilities for his care, Oliver was forced to move and work as a child laborer and in the care of a very greedy woman named Mrs. Mann. Child labor was very common back then, and there was an actual law that was set to eliminate poverty by starving the poor, that was called the Poor Law of 1834.(The Life of Charles Dickens;John Forester) Dickens used this law in his story to satarize the living in London, in the 19th century, and probably because he experienced child labor when he was growing up, and therefore tried to emphazise the way he lived back then. As soon as Oliver turned nine years old, Mr. Bumble, the beadle of the parish which where Oliver was born, took Oliver with him to work as an oakum picker. But because of the increasing of poverty, Oliver and the other workers were only fed little pieces of food. In the midst of starvation, one of Oliver's friend pursued Oliver to ask for some more food, and by that, Oliver was taken to a dark room for a week for his "disrespectfulness." Perhaps, Dickens was trying to tell the readers how the life of a poor boy be so unimportant to those who dominates him, and thus the other children living in povety also. This challenge of Oliver's life is just preparing him for the other eventful changes in his immediate future. Soon after, a reward was posted on a board for anyone who would like to take an orphan boy to their care, and will be offered five-pounds. Mr. Gamfield was willing to accept the boy for a bribe of five-pounds, but because of his bad publicity, meaning he had already lost the lives of several of his apprentices, he was told to be paid three- pounds and ten-shillings, instead of the five-pounds that was promised. Mr. Gamfield agreed to the proposition, and so did the board. Later, brought before a local judge for approval that Oliver was to be cared by Mr. Gamfield, the near sighted judge, searching for his ink bottel, caused him to look at the frightened face of Oliver, and then quickly realized that he would do something wrong if he let Oliver go with Mr. Gamfield, dropped and refused to sign the papers of approval, and told Oliver to return to the workhouse where the offering of five-pounds to anyone that
