Analysis Of Gangs Essays (1679 words) - Criminology, Crime

Analysis of Gangs Gangs are a violent reality that people have to deal with in today's cities. What has made these groups come about? Why do kids feel that being in a gang is both an acceptable and prestigious way to live? The long-range answer to these questions can only be speculated upon, but in the short term the answers are much easier to find. On the surface, gangs are a direct result of human beings' personal wants and peer pressure. To determine how to effectively end gang violence we must find the way that these morals are given to the individual. Unfortunately, these can only be hypothesized. However, by looking at the way humans are influenced in society, I believe there is good evidence to point the blame at several institutions. These include the forces of the media, theater, drugs, the government, and our economic system. By looking at the forces of the media, theater, drugs, and the capitalist economic system we can apply Akers' social learning theory and the Marxist theory as the cause of Gangs. Akers' social learning theory addresses the forces of the media, theater, and drugs. Akers' social learning theory states that criminal and delinquent behavior are acquired, repeated, and changed by the same process as conforming behavior. It also addresses four major concepts of differential association, definitions, differential reinforcement, and imitation. It goes on to say that this process will more likely produce behavior that violates social and legal norms than conforming behavior when persons differentially associate with those who expose them to deviant patterns, when the deviant pattern is differently reinforced over conforming models. Marxist's theory has capitalism the as the cause of crime. Marxist theory states that ownership of the means of production by the capitalist ruling class produces a society that is inherently criminogenic. The theory believes that the crimes committed are either, ?crimes of accommodation or crimes of resistance to the capitalist system. On the surface, peer pressure and greed cause gangs. Many teens in gangs will pressure peers into becoming part of a gang by making it all sound glamorous. Money is also a crucial factor. A kid (a 6-10 year old, who is not yet a member) is shown that s/he could make $200 to $400 for small part time gang jobs. Although these are important factors they are not strong enough to make kids do things that are strongly against their morals. One of the ways that kids morals are bent so that gang violence becomes more acceptable is the influence of television and movies. This is an example of the social learning theory. The average child spends more time at a TV than she/he spends in a classroom. Since nobody can completely turn off their minds, kids must be learning something while watching the TV. Very few hours of television watched by children are educational, so other ideas are being absorbed during this period of time. Many shows on television today are extremely violent and are often shown this from a gang's perspective. A normal adult can see that this is showing how foully that gangs are living. However, to a child this portrays a violent gang existence as acceptable. 'The Ends Justifies the Means' mentality is also taught through many shows where the "goody guy" captures the "bad guy" through violence and is then being commended. A young child sees this a perfectly acceptable because he knows that the "bad guy" was wrong but has no idea of what acceptable apprehension techniques are. Gore in television also takes a big part in influencing young minds. Children see gory scenes and are fascinated by these things that they have not seen before. Older viewers see gore and are not concerned with the blood but rather with the pain the victim must feel. A younger mind doesn't make this connection. Thus a gore fascination is formed, and has been seen in several of my peers. Unfortunately kids raised with this sort of television end up growing up with a stronger propensity to becoming a violent gang member or 'violent-acceptant' person. "Gangs bring the delinquent norms of society into intimate contact with the individual."1, (Marshall B Clinard, 1963). So, as you can see if TV

Ethics in Abuse

Ethics in Abuse A couple of years ago in Knoxville, Tennessee there was a case of child abuse where a baby of just a few months old was shaken and abused to the point that it was left with severe brain trauma and required mechanical ventilation in order to live. Removed from the ventilator, the baby could not continue living. While the parents, which includes the dad who shook the baby would not agree to passively euthanize the child, the hospital decided the best thing to do was allow the child to do a peaceful death by taking it off life support. The reasoning the parents would not take the baby off life support was because the dad would be tried for murder instead of child abuse which is a lesser charger. There are a few ethical issues in this scenario. First, there is the issue of euthanasia itself secondly, the issue of keeping someone alive for personal gain is presented, and finally, there is the issue of determining whether the child was being kept alive based by the use of extraordinary mea sures.Life Support (album)Before continuing, there are few terms that need to be defined. First of all, there are two forms of euthanasia, active and passive. Active Euthanasia is defined as “using certain death-causing means to bring about or cause the death of a person.” (McKinnon). Passive Euthanasia is defined as “withholding or withdrawing certain treatment and letting a patient die.” (McKinnon) In the situation described previously, the issue at hand is Passive Euthanasia. Basically, even though the doctors actually removed the baby from life support that is not what actually killed him. The injuries that were inflicted by his father are what actually killed him. As a result, the ethicalness of Passive Euthanasia will need to be considered further.There is...

The Entertainment Industry Essay Example | Topics and Well Written Essays - 750 words

The Entertainment Industry - Essay Example The art cinema motivates its narratives through being real and authoritative. It shows us the real location of events as well as the real issues that we face daily. In order to change the main character of the movies, it is good to choose a character that has specific goals, well stated and is object oriented. The art of cinema is not concerned with the actions of the characters; instead, they are concerned with the reaction that they will get from people who watch the film. A better way of restructuring the art cinema would be putting emphasis on actors. This makes them feel that the welfare and role they are doing is important not only to the viewers but also to the producers, therefore, ensuring a good working relationship in the production of a movie. In ending some of the stories stated, it would be possible to change them as follows; In the art film â€Å"L’ Avventura† where character by the name Anna is lost and not found, it would be more appropriate to change t he plot and end it in a way that maybe the body is found dead in unknown place or maybe show her happily living with an unknown person. This makes the viewer know what happened to her in the end. In â€Å"a bout de soufflà ©Ã¢â‚¬  was the reason for Patricia’s betrayal of Michel remains unknown, the plot could change in a manner that she writes and leaves a note explaining why she betrayed him. Such changes will make the viewer contended after watching the film since they are fully aware of what happened rather than leaving them in suspense.

The Search for Exoplanets

The Search for Exoplanets Daniel Davies Throughout the history of humanity, numerous scientists have been intrigued by the search for inhabitable exoplanets. To date, such ventures are still in the developmental stages and the discovery of life beyond earth and the solar system , regardless of how primitive it may be, may soon be regarded as a fundamental breakthrough in astronomy (Jones Mukai, 2007). The fundamental properties to be considered if a place is habitable are: presence of organic materials, water and energy sources. Habitability of the planet also takes into consideration, nearness of the planet to the sun, the duration of existence of life and not necessarily, that life is present or has ever been. The search for life in exoplanets has been ongoing for over a decade (Su, et al. 2011). The search has been difficult and lengthy and there have been no results showing the existence of life outside earth. The S.E.T.I or Search for Extra Terrestrial Intelligence project is probably the most famous experiment withi n this focus of study. Why the search for inhabitable exoplanets?: With the powerful view of telescopes, scientists have been able to view beyond our solar system. Planetary scientists have continuously been searching for exoplanets (planets beyond our sun) that can support life. However, they cannot view these planets in detail as they are so faraway (Su, et al. 2011). The closest known exoplanet orbiting star is called Epsilon Eridani, which is 63 trillion miles away – it is close to 14,000 times away from Neptune, the farthest planets in our solar system (Horner Jones, 2010). Due to the great distance, exoplanets cannot be viewed directly since the amount of light they reflect is too faint to be detected from a far off distance (Horner Jones, 2010). Alternatively, scientists infer the presence of an exoplanet from the changes in wavelength of light illuminating from the star, this may be caused by the gravitational pull from an orbiting planet or the regulation of brightness of the star due to transiting planets. When the Fermi Paradox was proposed initially, most people thought planets were rare. Nevertheless, since then the astrological tools have discovered the existence of numerous exoplanets. However, with each new discovery of an earth-like planet for instance, Epsilon Eridani, it becomes less likely that there could exist a planet apart from the Earth that can support life. Using methods such as those stated above, scientists have been able to discover hundreds of exoplanets and the first detection was in 1995. Once they detect one, they begin evaluating it to ascertain whether it can support life. Further, they analyze the light spectrum that radiates from the star in order to reveal the properties of the planet. The hunt is still on for planets, which are about the size of earth and those that are at the right distance from the sun. This is done in a region known as the habitable zone, or sometimes referred to as the Goldilocks Zone. The habitable zone is the belt bordering a star where temperatures are optimum for liquid water. The Earth lies within the habitable zone of the sun, which is the star. Beyond the habitable zone, life is impossible as it could be too cold and frozen to support life. Therefore, a planet that lies between a star and a habitable zone would be too hot and steamy to support life. Ideally, most astronomers like to know more about the atmosphere of viable habitable exoplanets. In light of this, they study the molecular makeup of the planet in search for traces of greenhouse gases that have escaped that could be an indicator of an inhabitable planet or they can be able to pick up traces of oxygen, water, carbon dioxide, methane that indicate a planet is habitable (Horner Jones, 2010). The notion that planets beyond the Earth can support life is an ancient discovery. Since the late 20th century, there have been two breakthroughs in this field. Through observation and exploration by robotic spacecrafts of other planets and orbits within the solar system has provided scientists with vital information regarding habitability criterion and provided geophysical conditions for comparing life on Earth and on other bodies. Exoplanets were discovered in the 1990s and has been fast paced thereafter hence providing information for the possibility of extraterrestrial life. The findings have further confirmed that the sun is not peculiar among the stars and planets and hence this has expounded the possibility of life beyond the solar system. The earth is the only known planet in the universe that harbors life, despite recent evidence to suggest organic materials were found on Mars, this is only an indicator of what might have been. Nevertheless, there are estimates of habitable areas around other orbits. Additionally hundreds of exoplanets have been discovered, which has created new insights into other habitable places in the universe. In November 2013, the Kepler Space Mission data released stated that there were about a billion earth-sized planets that were orbiting within habitable zones within the Milky Way Galaxy. Methods used in the search for inhabitable exoplanets: Exoplanets do not emit any light of their own and are obscured by other brighter stars, this makes them difficult to detect. Moreover, normal telescopes cannot be used to view them. This is called Direct Imaging and is not the best way to identify exoplanets , however the technology and ideas behind it are seeing an advancement and could produce promising experiments in the future. Therefore in order to identify exoplanets, a number of techniques are used to detect them and the impacts that they have on the stellar system. Below is a summary of common methods used to detect inhabitable exoplanets (Horner Jones, 2010). Pulsar timing: Pulsars refer to neutron stars that have misaligned magnetic and spin axes. As the pulsars rotate, they emit flashes of radio waves that travel to earth at regular intervals. The radio flashes can be detected and timed. The intervals between the pulses are very regular and are more accurate than the ticks of an atomic clock. A planet that orbits around a pulsar will cause slight variations to the timing of the flashes, which can be used to detect it. The first exoplanet that was orbiting around a pulsar PSR B1257+12 was detected through pulsar timing in 1992. Radial-velocity: A planet that orbits a stars exerts a little gravitational pull that makes the star wobble a little about the barycentre which is the system’s centre of mass. If the planet’s edge is aligned to the Earth, this wobble can be observed as a ‘Doppler’ shift in the light emitted by the earth. When a star is travelling away from the viewer, the wavelengths of the emitted light shift with respect to the velocity the star is moving at , hence the wavelengths shift to the red end of the spectrum and towards us the blue end of the spectrum. The planet’s gravitational pull is minute and hence, very accurate spectroscopic measurements are needed. On measuring the radial velocity it is therefore possible to determine the exoplanet’s orbital period, however the size of the planets cannot be determined. Astrometry: This technique utilizes extremely definite measurements of the position of stars in order to detest the tiny shifts that are caused by orbiting planets. This method is highly effective for planets that orbit face-on where the motion positioning is at its greatest, nevertheless, the measurements are difficult to obtain. Gravitational lensing: Einstein’s theory of relativity deduces that massive foreground objects bend the light from background objects by their pull of gravity. The bending of light causes a ‘lensing’ effect that magnifies the background objects that are distant, allowing the curving of light so that distant planetary transits can be observed. Photometry: Many scientists utilize this transit technique. It shows that when a planet passes in the anterior of its parent’s star edge, there is a decrease in the brightness of the star that can be detected. The periodic decreases in brightness may indicate the presence of an exoplanet, the measurements of light curves and spectral type of the star may give an indication of the size and orbital duration of the planet. When this method is combines with Radial velocity a number of parameters can be inferred accurately including the mass of the planet, which can determine the composition of the planet. The presence of methane and oxygen in an exoplanets atmosphere could be a strong indicator of a bio signature or evidence of past or present life in an exoplanet (Jones Mukai, 2007). Methods today are used to gain a good estimate to the temperature and size of an exoplanet so as to ascertain whether liquid water can exist on the surface of the exoplanet, this is one of three criterion to as certain whether a planet can support life. Figure(1): Shows a plot of results from a dwarf star in another solar system , I have highlighted the transits with the blue segments , taken from my planethunters.org, account Figure 1 clearly shows the dips in output from the light source, which is the dwarf being observed. The dips are huge indicators to an exoplanet transiting the star. Photometry is by far the most common form of finding new exoplanets. Impacts of the results: The results show that powerfully life on Earth highly affects the environment, and the feedback cycle loops. The impact of earthly life on cloud cover is an example. Clouds are composed of either water or carbon dioxide and therefore have a huge impact on the habitability of the planet through the greenhouse effect and that albedo. (Albedo is the surface reflectivity. High albedo surfaces reflect back most of the light and heat that falls on them, while low albedo surfaces absorb energy (Chambers, 2006). High albedo clouds maintain the coolness of a planet by reflecting instead of absorbing stellar energy. From research on earth, plant life contributes to more cloud cover. Likewise, airborne microorganisms in an exoplanet’s atmosphere can be seeds that lead to more cloud formation. The effect can lead either to cooling of the albedo or to warming because of the greenhouse effect (Fujiwara, et al., 2010). In both cases, clouds or a lack therein may change the habitability, hence altering the planet’s temperature in one way or another. Life may also alter the carbon cycle. Plants on earth affect the quantity of carbon dioxide in the air, calcareous plankton have had major changes in the Earth’s carbon cycle (Fujiwara, et al., 2010). The systems have effects on the heat trapping properties of the atmosphere and alter the chemistry of the atmosphere and hydrosphere. Once exoplanets become hydrated, their impact will shift from affecting the delivery of volatiles to arid lands and hence will affect developments in life. Due to developments in our world, such as industrial revolution and technological advancements(Alvares et al, 2008), a number of species of biodiversity have become extinct and a great number of micro-organisms contributing to geochemical cycles have been extinguished (Chapman Morrison, 2004). Although these are believed to have been cause by a myriad of other factors, a few of these have been caused as a result of the collision between the earth and other small heavenly bodies. At face value, most people assume that more favorable life conditions would be developed if a host planet were discovered, however, mass extinctions will have to occur in order to trigger an influx into these alien bodies. Ever since it was discovered that collisions with asteroids and comets could lead to significant threats to human life on Earth, the idea that the impact rate on those bodies on earth would be much greater were it not for the protective influence of planet Jupiter (Chapman Morrison, 2004). Were it not for the mass and placement of Jupiter within the solar system , the earth could have been more punishing throughout its evolution, which would have entirely prevented the evolution of life on earth. The earth is a habitable planet that is an incredibly rare and unique place and that life should be very scarce or even non-existent anywhere else in the universe. It is now well acknowledged that asteroids and comets have bombarded the earth for decades. When it was first discovered that the impacts of craters on earth were the effects that resulted from the collisions between the earth and other solar systems, the greatest majority of the objects crossing the earth were comets (Chapman Morrison, 2004). A significant fraction of the earthly bodies were ejected from the solar system due to the distant perturbations by the Jupiter leaving a significantly, greater number of transiting orbits that could threaten the earth’s ecosystems. Conclusions: At face value, most people assume that more favorable life conditions would be developed if a host planet were discovered, however, mass extinctions will have to occur in order to trigger an influx into these alien bodies. The quest for an inhabitable exoplanet is a threat to humanity as it could trigger harmful effects on earth such as the collision of comets and the earth, which could lead to drastic effects such as volcanic and crater eruptions, which will have drastic effects on humanity. This means that the search for an exoplanet is indeed a search for our own preservation, eventually the earth will be swallowed by the sun , the human race will need somewhere else to live. The big question on peoples minds is , will we ever get there ? The answer to this is in the near future , certainly not, but in the far future , perhaps. With the promise of new technology coming , the ability to predict rapid changes in our space transportation may be obsolete, in truth we dont know. Bibliography: Alvarez. L.

Lysergic Acid Diethylamide Essay -- Drugs Sixties Health Essays

Lysergic Acid Diethylamide The late sixties were a time filled with sex, drugs, and rock and roll. A huge part of American culture at the time was focused around these three things. Musicians possessed a tremendous amount of social influence, and like wise, society put a lot of emphasis on the lives and attitudes of musicians. Of the rock groups from this time period, the Beatles were by far the most influential. The British rock group was probably the most catalytic band in rock and roll history. Although they came together in the shadow of the Beatles, another band of that era was Jefferson Airplane. Jefferson Airplane was deemed the first of the San Francisco psychedelic rock groups. Jefferson Airplane was always considered to be a psychedelic rock group, but it was not until later in their existence that the Beatles fell into this category as well. Both groups earned this title for their creative style of rock as well as for their experimentation with drugs. Each of these groups wrote songs that alluded to drug use at one time or another. Two of the most criticized songs from these bands are Lucy in the Sky with Diamonds by the Beatles, and White Rabbit by Jefferson Airplane. White Rabbit is a song latent with drug references. The connection with drugs in Lucy in the Sky with Diamonds is not as clear. Although John Lennon claims that he had no intention of making references to LSD in his song, the abstract lyrics and metaphoric language invite drug connotation. Lucy in the Sky with Diamonds and White Rabbit mirror each other in their association with LSD and their allusions to Alice in Wonderland, but looking into these songs more deeply it is obvious that both artists were writing about escape; escaping reality. Lyserg... ...ame out of the late 1960's. Both songs were criticized for their relationships to drug use and possible influence on impressionable youths. It was the media, the fans, and the critics that Jefferson Airplane and the Beatles were trying to escape from. It was through their music, Alice in Wonderland, and a drug called LSD that they were able to do so. Works Cited "The Beatles Ultimate Experience Database: Songwriting and Recording Sgt.
