The Debate Of Rehabilitation Vs. Reparation - 948 Words
A common dilemma in the United States prison system is the debate of rehabilitation vs. reparation. Reparation involves strictly punishing the prisoner for their crime. On the other hand, rehabilitation aims to ââ¬Å"fixâ⬠the prisoner for a potential eventual return to society. Ethically, reform makes more sense than reparation, as it aims to make the prisoner more useful to society, while increasing the overall safety of the society. A strong rehabilitation program would additionally cut down the number of repeat offenders, which is financially responsible as it is very expensive to keep a prisoner behind bars. One of the most effective methods of reforming prisoners is continuing their education. Furthering the education of prisoners helps to improve their quality of life upon release, and proves to be fiscally responsible as it cuts down recidivism rates. The United States is the worldwide leader in total prison population, with 2,217,947 imprisoned people. China, the next closest country, has 1,649,804 imprisoned people. This statistic becomes even more startling when the total populations of the United States and China are compared. The United States is home to about 318.9 million people, while China is home to 1.357 billion people. Around .1% of the population of China is in prison, while nearly .7% of the United States population is in prison. As of 2010, keeping someone in prison for a year cost about $31,000.

Wealthy and Lower Socioeconomic Communities Differences Free Essays
There exists an achievement gap among wealthy and lower socio economic communities. Students who come from schools within lower socioeconomic communities do not often receive the same education or services from wealthier districts. New Jersey has responded to this inequitable situation with the Abbot funding process. We will write a custom essay sample on Wealthy and Lower Socioeconomic Communities Differences or any similar topic only for you Order Now Recently two local communities, Long Branch and Neptune, have been threatened with the loss of their Abbott status; as a result of additional mandates from the federal No Child Left Behind Act, many such schools are being threatened with the loss of their funding if they fail to meet minimum academic achievement standards. To determine the impact of this potential loss, this paper will provide insights into local concerns in Long Branch to identify how this loss would affect the academic achievement gap. This discussion will be followed by a report on two areas where it is believed equity will be lost to the district. In their Abbott vs. Burke decision, the New Jersey Supreme Court mandated additional assistance for the stateââ¬â¢s 30 poorest districts, including Long Branch and Neptune (Quinn, 2003). According to an Asbury Park Press survey of enrollment data for Monmouth County found that minorities comprise the majority of the school population in Asbury Park, Red Bank, Neptune, Freehold, Long Branch and Lakewood; of these, the survey found that only Red Bankââ¬â¢s poverty rate does not exceed the stateââ¬â¢s rate (Quinn, 2003). Furthermore, fully 20 percent of the Hispanic students in Monmouth County attend the Long Branch school system (Quinn, 2003). If the additional funding promised by the Abbott decision is halted or reduced, all of the low-income communities will undoubtedly experience further declines in the academic performance levels that are already precipitously low in many cases, with the thrust of this reduction in funding creating two fundamental problems: 1) adversely affect literary rates; and 2) further exacerbate the segregation of low-income and minority citizens into pockets of poverty. As to the first issue, Strickland and Alvermann (2004) reviewed the issues concerning the achievement gap in the U. S. and found that literacy demands of the middle grades are exacerbated when the students come from low income and minority homes; in particular, these issues assumed critical levels when the students are members of low-income and minority families. These students are already likely to attend schools characterized by high mobility rates, inadequate resources and facilities, and large numbers of young students with challenging learning needs (Strickland Alvermann, 2004). Comparable trends are also apparent in the State of New Jersey as well. According to Lattimer and Strickland (2004), the results from the Grade Eight Proficiency Assessment (GEPA) from 2000-2002 identified consistent differences in partially proficient, proficient, and advanced proficient between District Factor Groups (DFGââ¬â¢s) and race/ethnicity. In addition, the differences in academic achievement between special needs districts such as Long Branch and non-special needs districts found similar trends to the 2002 GEPA (Lattimer Strickland, 2004). In fact, a 35-percentage point difference existed in the total number of students scoring proficient and advanced proficient in Language Arts Literacy in 2002; the authors point out that the District Factor Group is an indicator of the socioeconomic status of citizens in each district and has been useful for the comparative reporting of test results from New Jerseyââ¬â¢s statewide testing programs in the past (Lattimer Strickland, 2004). Concerning the second issue of further segregating low-income and minority citizens into ââ¬Å"pockets of poverty,â⬠the school superintendent for Long Branch reported that although minorities tend to live in segregated communities, this was the result of a ââ¬Å"social trendâ⬠rather than segregation; notwithstanding these assertions, though, these high concentration of low-income minority members in their own communities has created ââ¬Å"haveâ⬠and ââ¬Å"have-notâ⬠districts, with the Long Branch district representing one of the hardest-hit in the state (Quinn, 2003). Clearly, if the Abbott funding is halted, parents will be faced with a dual-edged dilemma of being unable to provide their children with an adequate education by virtue of substandard schools while being forced to remain in these low-income districts out of sheer necessity. The people of New Jersey in general and the citizens of these low-income regions deserve the quality education that is their American birthright; unfortunately, the promise has not lived up to its legacy in many of these cities, and Long Branch continues to be threatened with even more academic and social miseries if its Abbott funding is stopped.

Rogue Waves an Example by
Rogue Waves A killer wave, known to mariners as a "rogue wave," was approaching a desolate area of Baja California below Ensenada. It had been born off the east coast of Australia during a violent storm; it had traveled almost 7,000 miles at a speed of 20.83 miles an hour. Driven by an unusual pattern of easterly winds, it was a little over 800 feet in length and measure about 48 feet from the bottom of it trough to its crest. On its passage of the Pacific, it had already killed thirteen people, mostly fishermen in small boats, but also an entire French family of five aboard a 48-foot schooner...

One freak wave could roll her over and put eighty men in the water. - Sebastian Junger, The Perfect Storm : A True Story of Men Against the Sea (1997) In February 1933, the U.S. Navy steamship Ramapo was traveling to Manila from San Diego when it experienced a severe storm. Gale-force winds raged for several days, 50-foot swells brewed in the North Pacific. It was in these circumstances that the ship encountered one truly enormous upsurge of water. The officer on watch triangulated the monster wave and calculated its height at 112 feet equivalent to a ten-story building. It is still the biggest wave ever reliably measured. It is called a rogue wave. Rogue waves are monstrous waves of drastically larger dimension than the surrounding swell. They are defined as large amplitude waves whose heights exceed two times the significant wave height of the background sea. (Significant wave height or SWH is defined as the mean of the largest third of waves in a wave record.) According to naval hydrography terminology, waves 15 to 25 feet high are called sneaker waves, and waves100 feet high or over are classified as freak waves or rogue waves. They are likely to occur where a swell encounters a current that is moving in a curved path, or an eddy at it is called (Environmental Literacy Council, 2006, para 2). Rogue waves are also caused by the accidental meeting of two or more relatively smaller waves. Open-ocean swells travel in wave trains and even in the same wave train, individual swell heights can differ. But when wave trains from different storms meet in the open ocean or in areas where there are strong currents, individual waves can combine their energy to form a surprisingly massive wall of water, which is known as a rogue wave. Thus a rogue wave is seen to be originating in a rare confluence of crests (Garrison, 2005, p.239). However, it is not clear how a simple superposition of waves, resulting in constructive interference, can result in waves of such gargantuan size, which moreover seem to occur not too infrequently. Rogue waves represent a transient ocean phenomenon that usually occurs in the deep interior of the ocean, and plays out on relatively small surface areas in the vast ocean expanse. Though usually associated with storms, sometimes these rogue waves can arise out of nowhere in only mildly agitated ocean waters and disappear just as quickly, usually creating havoc if some ships happen to be traversing in their path. Even huge and robust vessels are known to be no match to the fury of ocean as manifest in rogue waves. Though mariners have always been aware of the 'freak' wave phenomenon, owing to lack of any reliable empirical data, these waves could not be predicted or quantified, and so could not be taken into account during the design process of a ship (Rawson & Tupper, 2001, p. 174) New ships are designed on the basis of previously successful models which have withstood very abnormal conditions, but most vessels that are built even today are simply not designed to weather the assault of a colossal rogue wave. Rogue waves have for long remained the dreaded stuff of legends. Until well into the twentieth century, there was only sparse anecdotal evidence for these towering infernos of the sea, and scientists tended to classify the tales surrounding the monstrous waves as sea mythology that dealt with sea monsters, mermaids and so on. It was generally known that in any wave system, after a long enough time, an exceptionally high wave would occur. Nevertheless statistical models of sea states which have been used to predict the occurrence of extreme waves either concluded that waves over a hundred feet to be either a physical impossibility or as something which could occur only once in a thousand years (Schober, 2004, p.194). However, several instances of hard evidence, improved mathematical theory, and satellite survey data in the more recent times have all now converged to prove the existence of the monstrous waves beyond a tinge of doubt. Nowadays they are acknowledged to be a natural pheno menon of the ocean, just as tsunamis and mega-tsunamis are, though their causes and characteristics are different. The freak waves are no longer regarded as freaks really. Even so, the rogue waves are considered very rare, and rather elusive; improbable but still possible.. Rogue waves are definitely anomalous events in the sense that they fall outside the distribution of wave heights predicted by orthodox wave theory. Yet they are no longer thought of as unexplained quirks of nature, though scientists still very much a lack an adequate understanding of them, especially of their underlying causes. Scientific and mathematical advances in the recent years and decades, however, have led oceanographers to calculate their probability of occurrence, with the help by extensive wave data from buoys, ships and satellites. It is still not possible to predict their exact time of occurrence, though. Mathematical models are now able to predict where they are likely to form in general, although the exact location cannot be pinpointed. The problem with understanding the rogue wave phenomenon is the highly complex non-linear mathematics that underpins it. The occurrence of rogue waves takes place in what is mathematically called a chaotic regime. According to the newly emerging science of chaos, some small perturbation in local conditions could crescendo into a disproportionately huge effect. But rogue waves are gradually becoming more understood. The Benjamin-Feir instability and nonlinear focusing have been proposed as a mechanism for the generation of rouge waves in deep water. Also, certain homoclinic solutions of the nonlinear Schrodinger (NLS) equation have been observed to exhibit many of the properties of rogue waves in deep water (Schober, 2003, p.735). A deeper understanding of the mechanism by which rogue waves are formed is likely to help us narrow down our predictions about them, and thus save many lives. More extensive studies and investigations into rogue waves are not only essential for a better theoretical understanding of the dynamics of ocean but also to avoid a good deal of the huge losses to life and property that routinely occur in the seas. On average, it is estimated that approximately two large ships sink at sea every week and rogue waves have been the purported cause behind a fair number of these sinkings. Though there may certainly be other causes behind the many mysterious ship losses, scientific analysis of the wrecks of ships sunk in recent decades indicates that a significant proportion of them have a damage pattern that seemed to suggest the hand of monster waves which can swell over a hundred feet. The sinking of many a supertanker in the latter part of the twentieth century has also been associated with rogue waves. In addition, there is some evidence that average wave heights are slowly rising and that freak waves of eighty or ninety feet are becoming more common. This trend is attributed to the intensification of the greenhouse effect which has made storms more frequent and severe. As a consequence, stresses on ships have been increasing along with the need to understand, predict and prepare for these monst ers of the sea. References: Environmental Literacy Council. (2006).
