Only True Love Exists Above The Moon - 1836 Words

Only True Love Exists above the Moon What is love? At the risk of sounding clichà ©, this question warrants closer inspection, for the answer to this age old question has been a topic of discussion for the millennium. Due to the complexity of love and the different applications of the term, from loving foods to cars to people, it is difficult to come up with one standard definition of love. Even when people narrow the scope of love to just human interaction, there is still ambiguity, namely between whether love is rooted in physical attraction or spiritual union. John Donne offers his own version of love in A Valediction: Forbidding Mourning,† a vision of love grounded in spiritual, refined connections over physical attachments. Geoffrey Chaucer’s, â€Å"The Miller’s Tale,† on the other hand, interprets this same concept differently, with crude allusion, humorous scenarios, and characters driven by sex. Although these two stories are extremely different, Chaucer and Donne both try to create a philosophy about the same concept, love, and, as seen by their works’ different endings, both come to the same conclusion that true love is an emotional, unified connection that transcends mere physical attraction. Both Chaucer and Donne tackle whether proximity is an essential component of true love; however, they differ in their views of its significance, as Chaucer finds it indispensable, while Donne argues the opposite.

Sociological Theories and Gang Violence Essay Example For Students

Sociological Theories and Gang Violence Essay SOCIALOGICAL THEORIES and GANG VIOLENCE Abstract The sociological analysis of gang membership explores the different types of effects that arise due to criminal involvement. Because of the social conflicts that are associated with gang membership, this paper will explore the different theories of social learning and both personal and control issues that relate to the recent surge in crime across Chicago. As we open the doors of a crime ridden society, the truth begins to unfold. It isnt Just the thought of helping, it is the action that remains the barrier between living a life of crime or a life that carries hope. The number of violent encounters has readily declined, yet, violence has flooded the streets of Chicago, Illinois. In 2012 there were over five hundred murders committed in the city of Chicago alone (Lemmer, Bunsinger, Lurigio, 2008). The desensitization of communities have become more apparent as the acceptance of gang activity has become part of the norm. Observation of vicarious behavior by other social groups suggest that the rationalization of choice is desired, so long as gangs conform bonds across city streets (Lilly,Cullen, Ball, 2011). Predicting the future is not too far- fetched, when it comes to socialization. Many theorists suggest that society cant anora acceptance 0T crlme wltnout accepting some responslDlllty Resulting Trom tne absence of internalized rules and regulations, criminal behavior is governed by the justice system (Lilly,Cullen, Ball, 2011). Stepping deeper into the recent gang activities, that have prevailed in society within Chicago, former Gangster Disciple Harold Ward, speaks of the corruption among leaders in the city and their approval of the cartels from Mexico who have taken over their society as a whole (Pundit, 2013). Whether people agree or disagree, social disorganization among their neighborhoods s one of the dominant perspectives that defines criminalization of gang members. In order for the decriminalization to occur there needs to be further organized programs within the communities across our nation. I continue to speak of the statistics about Chicago, but there is more than Just one city across the United States that suffer the threat of gang violence every day. According to FBI statistics, there are 1. 4 million active gang members in the United States today. Statistics show that although gang violence has decreased overall in numbers, it still remains prevalent in many neighborhoods today. Murder rates have soared over the past few years on the streets of Chicago (Lemmer, Bunsinger, Lurigio, 2008). In fact, in 2012, the city of Chicago had over 400 murders of which 80% is gang related. These murders occurred because of gangs fghting over turf, attempting to uphold their reputation, and retaliation against one another. According to former gang member Harold Noonie Ward, the violence on the streets of Chicago stem from the Mexican drug cartels. He believes that the city of Chicago has become a haven for these cartels to place their people. Even though many of the higher ranking members of the gangs re locked up, the mass amount of drugs entering Chicago has not seized. Noonie believes that there are many officials who are profiting from the drugs that are being brought in and thus refusing to make it stop (Pundit, 2013). News reports show that in Chicago alone there are 100,000 gang members per every 12,000 police officers (Rosenzweig, 2013). These are obvious numbers that outweigh one another. On a national level 40% of all homicides (in major cities) were gang related and in 2011 gang members were responsible for 61% of homicides. The average age of gang members ranges from sixteen to nineteen, but some members are as young as hirteen. There was a 25% increase in gang activity in Chicago from 2009-2012 (Rosenzweig, 2013). The idea of violence and deviance has been long misunderstood. There have been several theorist that have taken their knowledge and created their own ideology of why an individual turns to violence as a way of life. Based on Ronald Akers ideology of social learning theory, many people commit crimes based on the observations they encounter. These observations can come from a number of sources such as, media, family, and peers. Family and friends as well as the social norms of a neighborhood can be influential to an individual because of cceptance. This theory also says that based on positive or negative reinforcements an individuals behavior will be based on the rewards or punishments that are given. If given an opportunity to change the violence that occurs among neighborhoods there are many who choose to do so (Akers, 1990). Social control and social learning both suggest that behavior is a choice based . However, when looking at the two theories they actually take a different stance. Social learning theory suggests that individuals Join gangs to feel that sense of security as well as living the glamorized IITestyle ana tnelr attempt to Till tne vola 0T an aosent parent. Soclal learning tneory Is best stated as learned behavior based on the environmental and social attachment that one has to a community. Social learning is telling us that people have a choice to make a rationalized decision based on their observations of others, but remain adamant to state that their interactions with the social surroundings will be taken into consideration as well (Lilly, Cullen, Ball, 2011). Social and personal Control, by Reiss suggest that deviant behavior is based on the bond that one shares with their social surroundings. An individuals defiance through socialization is questioned when determining how an individual reacts to the commitment that they have to their social surroundings. It also says that being a disappointment to their peers is a prominent indication of social control (Russell, 2006). An individual at this level will continue to be involved in a certain behavior as long as the social environment in which they encounter continues to be a believer of moral acceptance. Social behavior based on any given neighborhood can be predicted in theory, but having the ability to predict the factual outcome of a situation is implausible. Statistical facts give us an idea of the average range of where the violence is heading, but there are ways to change that (Chibnal Abbruzzese, 2004). Gang violence is not a limited issue, it is prevalent within many types of neighborhoods and different social classes. As much as we want to believe that the gangs are only in bad areas, we cant provide proof of just that. Sure there may be more gangs in a certain area based on the economical status, but that doesnt make it nonexistent for the high class. The flourishment of gangs in certain areas has been taken out of existence. A community must allow for esources to be allocated to prevent criminal activity among those involved. Another reason that people Join gangs is for financial security (Wyrick Howell, 2004). The Tragic Consequences of the Rebellion on Animal Farm Sample EssayRonald Akers and Albert Reiss may have walked into their theories with a different thinking, however after being researched, there were many areas in which both criminal justice and sociological connections bonded them as theorists. A social bond within a community, a fght to uphold their reputation, and being able to feel a sense of closeness within the refined family individuals Join gangs. Having the internalization of morals and guidance provides a foundation for those who are willing to give up the street life. The likelihood of reducing criminal activity among rural streets is not Just going to happen in one day, but it is going to take time and effort by a community who is willing and able to make a change. As we have looked into the two theories we have learned that indirectly they have an effect on one another. Crime and delinquency results from the lack of parenting , the lack of rules and regulations, unconfirmed social systems that emphasize morals, and established conformity among a community. In order for a community to be able to employ acceptance of techniques and measures as a whole there needs to be some sort of trust in the community. Safety needs to be among the highest of priorities (Lilly, Cullen, Ball, 2011). Gang members need help realizing the impact they have on the community. They need to know that their behaviors are a part of a vicious cycle that will continue to trickle down from one generation to the next. Gang members need to be reminded that there is a chance at change, and it can start with Just one person. The overall aspect of the theories is that if we enable children to learn in better environments, provide sufficient education, and instill values and morals to them at a young age, that we may be able to prevent them from conforming to gang life. Criminal Justice response needs to outweigh the bad with the good. They need to provide offenders with the stability they need before they are released back into the community. Young offenders need to be nourished and taught right from wrong in a egal perspective. Offenders need to be able to have to opportunity at change before they are Just thrown back out there with no security, no support, and no insight to how the current economy survives. Sociological reasons to crime can be defined in many different manners, but to Just accept them as the norm needs to be taken out as an option to these communities (Lilly, Cullen, Ball, 2011). People need to stop hurting each, and people need to start living for what life is really about. ReTerences Akers, R. L. (1990).

Smoking Is a Silent Killer Essays

Smoking  Is a Silent Killer Essays Smoking  Is a Silent Killer Essay Smoking  Is a Silent Killer Essay Smoking  Is a Silent Killer Researchers claim that smoking is detrimental to memory . Prolonged heavy nicotine use has a negative effect on day-to-day memory, according to research. Researchers from five universities asked smokers and non-smokers to rate their long-term memory, for example remembering to send birthday cards. They found that smoking significantly impaired memory, with heavy smokers reporting the most errors. The survey was carried out by teams from Newcastle, Wales, North Umbria, Westminster and Teesside universities. The survey nvolved more than 700 people. Researcher Dr Tom Heffernan, of the human cognitive neuroscience unit at North Umbria University, also tested everyday memory including remembering where people had put things. The teams also took into consideration how much people smoked a heavy smoker was classed as having more than 15 cigarettes a week and alight smoker between one and four cigarettes a week. Dr Heffernan said: The result of the study reveal ed that smokers reported more errors in their long-term memory than non-smokers with an additional ifference between non-smokers and heavy smokers. There was also a significant detrimental effect of cigarette use on everyday memory function. For example a typical heavy smoker reported 22% more memory-related problems than a non smoker and around 12% more problems than those who smoked only relatively a small number of cigarettes It is concluded that chronic, heavy smoking is associated with impairments in everyday memory, although the precise nature of the deficits are as yet unknown.

Mineral and Rocks Essay Example | Topics and Well Written Essays - 1000 words

Mineral and Rocks - Essay Example There is one universal physical property which is common in all the minerals i.e. all the minerals exist in solid form in nature and cannot be in the form of liquids. Moreover minerals have come into existence by the natural activities and the changes which took place during the evolution of the planet earth and human activities have no involvement in the creation of minerals, â€Å"Earth Science: A Scientific History of the Solid Earth†, Michael Allaby (2009). Chemical formulas depict the chemical composition of the chemical compounds and minerals are also classified as chemical compounds. The structure of most of the minerals falls under the category of the crystalline structured solids. The elements in minerals are arranged as crystals. According to â€Å"Earth Science: A Scientific History of the Solid Earth†, Michael Allaby (2009), almost all of the minerals are inorganic in nature. One of the examples of minerals is common salt (sodium chloride). Common salt has a ll the characteristics which have been identified for a mineral. Being solid, composed of chemical compounds, it is inorganic. Moreover common salt is created as a result of natural phenomena and its structure is crystallized. The chemical association of silicon and oxygen yields silicate minerals. These silicate minerals are then added on by other elements which give particular properties to the silicates. According to the elements and crystals which join the silicate minerals are iron (Fe), magnesium (Mg), potassium (K), sodium (Na), and calcium (Ca). The structure of silicate minerals is the basis of their classification in different groups. The different silicate groups include Micas, Quartz, Amphibole group, Olivine group and Pyroxene group. Micas and Quartz contain Biotite and Muscovite groups. Moreover Feldspars which make half of the Earth crust are also silicate minerals and are further classified as Potassium Feldspar and Plagioclase. The mineral rocks have been classified into three basic groups on the basis of their origin; these groups are sedimentary rocks, igneous rocks, and metamorphic rocks. Certain natural processes resulted in the formation of these rocks. Magma is a molten material which is present deep inside the Earth and is molten because of the high temperatures inside the Earth. Magma is the source of formation of the igneous rocks which are formed as a result to freezing and thawing of the Magma. The molten material is pushed upward to the ground and is cooled by the natural processes. After cooling the resultant solid material is known as igneous rocks. The second type of rocks is the sedimentary rocks. Sedimentary rocks as the name signifies are layered rocks with different layers of materials lying closely over each other resulting into a rock solid material known as sedimentary rocks. The weathering processes which includes erosion deposited various minerals from one place to other, these layers of minerals resulted into the forma tion of sedimentary rocks. When the same sedimentary rocks and igneous rocks are subjected to conditions of high temperature and pressure their structure changes somewhat and yield another category of rocks which is known as metamorphic rocks â€Å"Petrology: Igneous, Metamorphic and Sedimentary†, Harvey Blatt, Robert Tracy, Edward Owens (2006). The three categories of the mineral rocks h
