High School Dropouts At Risk Students - 1419 Words

Introduction High school dropouts are usually defined as students who leave school before obtaining a diploma but in some cases, are also labeled as a drop out if they do not complete the high school curriculum within four years after entering ninth grade (Hampden-Thompson, Kienzl, Daniel, Kinukawa, 2007). Students who are considered to be at risk are more vulnerable to dropping out of school than others. These at risk students usually exhibit behavioral, attitudinal, or academic problems (Lemon and Watson, 2011). However, other factors do contribute to dropping out which include family issues, health issues, mobility, and cultural issues. According to Laqana (2004), high school dropouts present serious implications for society such as reduced earnings, higher unemployment, increased crime rates, increased teen pregnancy, and increased alcohol and drug abuse. Currently, there are approximately 1.3 million annual high school dropouts who might lose $355 billion of income over the ir lifetimes (Bornsheuer, Polonyi, Andrews, Fore, Onwuegbuzie, 2011). It is also noted that the prison population in some states is comprised of fifty to ninety percent of high school dropouts. Whannel Allen (2011), identified a number of aspects of the school experience which are relevant to school attrition. Usually it is a process that begins for many in their early years of school and several factors contribute to the final decision to stop attending classes. These factors can beShow MoreRelatedFactors Contributing to the High School Drop Out Rate Essay1569 Words   |  7 Pagesthe amount students that were a part of my class.

Oedipus the King A Tragic Hero Essay - 2117 Words

In most dramatic plays, tragedy usually strikes the protagonist of the play and leads him, or her, to experience devastating losses. While tragic instances can be avoided, there are other instances where one’s fate and future is out of the protagonist’s control. In Oedipus the King, written by Sophocles and first performed around 249 BC, Oedipus cannot escape his destiny and even though he tries to overcome and circumvent prophecy, he finds out that supernatural forces will get what they want in the end. Oedipus meets the criteria of a tragic hero set forth by Aristotle and his fate within the play demonstrates that one does not always have free will in their lives. Traditionally, in Greek drama, tragedy is meant to reaffirm the†¦show more content†¦(Aristotle) Moreover, â€Å"tragedy evolved from the choral lyric poem in honor of Dionysus, sung and danced around an altar of Dionysus in circular dancing place† (â€Å"Greek Tragic Drama†). In Oedipus the King, Oedipus can be considered to be the tragic hero of the play. Aristotle’s definition of a tragic hero holds that the tragic hero is â€Å"a person who is neither perfect in virtue or justice, nor one who will fall into misfortune through vice or depravity, but rather, on who succumbs through some miscalculation† (Brown). Aristotle also believed that the tragic hero’s misfortune or demise was not â€Å"wholly deserved† and that the punishment would exceed the crime that he or she committed (â€Å"Aristotle†). The tragic hero’s fall was also meant to serve as an allegory and intended to â€Å"raise awareness [or] gain self-knowledge† (â€Å"Aristotle†). In many cases, the tragic hero’s fall is due to a tragic flaw that serves as a catalyst for his or her demise. In other cases, supernatural forces help to cause the tragic hero to fall (â€Å"Tragedy: The Basics†). In the case of Oedipus, it is King Laius that initiates the conflict between himself and Oedipus who retaliates against the king and kills him in self-defense. When Oedipus is told the truth, he cannot understand what has happened, which is a direct result of being lied to about his biological parents. When Oedipus is finally able to piece together the fragmented facts thatShow MoreRelatedOedipus The King : A Tragic Hero1541 Words   |  7 PagesAristotle (384-322 B.C.) defines a tragic hero as one who possesses the characteristics of hamartia, peripeteia, anagnorisis, and that the characters fate must be greater than deserved (Else). Since the main character in Sophocles’ classic tragedy Oedipus Rex or Oedipus the King matches up to Aristotle’s definition, Oedipus certainly exemplifies what it is to be a â€Å"tragic hero.† The play’s protagonist Oedipus is revered as a good man and intelligent ruler who acts quickly to support Thebes- a cityRead MoreThe Tragic Hero Of Oedipus The King1528 Words   |  7 Pagesdescribes the tragic hero as having three components which should be present in order to influence the audience.

A key criteria of Aristotle’s tragic hero is that he or she comes from high estate, such as a royal family. Aristotle’s definition of the tragic hero is well thought out in this manner.

September 11 in International Relations Theory Essay Example For Students

September 11 in International Relations Theory Essay September 11 in International Relations Theory Essay An event as epochal as September 11 is bound to provoke theorists of international relations. Over the past year or so, there has been a race in academia to claim the first prize for the best theory to explain the events before and after September 11. The consensus is that the dominant discourse of realism has won, because it conceives of conflict and destruction as natural in an anarchical world (from Thomas Hobbes ;anarchical state of nature;). It also justifies Americas threatening military actions after the terror strikes as a natural form of behavior of strong states, which always bully the weak into compliance to serve the formers selfish interests. The more interesting contest is among the alternative theories to realism. It is a race for second prize, and the main competitors are feminism, globalism/neo-Marxism and pluralism. Feminism The fundamental premise of feminism is that international politics is a ;mans world and a gendered activity. Gender is a social construction based on ideas of autonomy, objectivity, sovereignty and virtu (Niccolo Machiavelli), of which only men and masculine states are allegedly capable. Writing after September 11, feminist novelist Arundhati Roy encapsulated this critique, saying, Women of the world stand between two extremes, both represented by androcentrism, Rambo culture and patriarchy Osama bin Laden and George Bush. Bin Laden reportedly has 42 wives and is a defender and instigator of Taliban-style hardline Islamic structural violence against women. Bush heads the most conservative American administration since Ronald Reagan, pursuing vested interests of the military-industrial complex and giant oil multinationals that extort women in the Third World (a line favored by Marxist feminism). Realist dogmas and metaphors of war of every man against every man and stag hunt (Jean Jacques Rousseau) have been pursued vigorously by the US government since September 11, accompanied by a culture of manliness and glorification of soldiers and ultra-patriotic themes in the media. Imperial brotherhoods (Robert Dean) among mujahideen and the Bush cabinet are waging destructive wars to quench their fanaticism and male egotism. Some feminists see the World Trade Center itself as a symbol of male capitalist egotism which ran into another kind of Arabic male chauvinism on September 11. Feminists also like to point out that the majority of women in the world, including Palestinians, mourned the deaths of innocents in the terror attacks, and called for a foreign policy of reconciliation instead of revenge. But state-centric military security orthodoxy dominates the discourse and active voicing of peace by women has been relegated to peripheral activity and condescendingly dismissed as human interest stuff (Ann Tickner). The outcome is that human security and common security, an all-encompassing concept including domestic non-violence, is sorely lacking as the US prepares for more wars. Feminist scholars have particularly lamented how the US has compromised with chauvinist male warlords in Afghanistan, who are only a shade better than the Taliban, and which is still claiming for propaganda value that American military action emancipated Afghan women. Feminist interventions since September 11 have labelled the event and its aftermath as an instance of patriarchal technology of destruction and domination. They urge a dire need to transform the realist paradigm and to include one half of the worlds population in deciding on foreign policy so that a more harmonious world and a ;just peace; can be arrived at. However, feminism has no unified tenor. Despite using phrases like ;sexual terrorism; (Dorothy Roberts) as a much bigger threat to human security than Islamic terrorism, feminists are a highly divided lot, with competing visions of ;radical feminism;, ;white Western feminism;, ;ecological feminism;, ;post-modern feminism;, et al. Feminist international relations deconstruct realist policies with gusto, but offer no alternative model for transforming practice of world affairs. .u59e0bc90eb53a83adf499263efd76e78 , .u59e0bc90eb53a83adf499263efd76e78 .postImageUrl , .u59e0bc90eb53a83adf499263efd76e78 .centered-text-area { min-height: 80px; position: relative; } .u59e0bc90eb53a83adf499263efd76e78 , .u59e0bc90eb53a83adf499263efd76e78:hover , .u59e0bc90eb53a83adf499263efd76e78:visited , .u59e0bc90eb53a83adf499263efd76e78:active { border:0!important; } .u59e0bc90eb53a83adf499263efd76e78 .clearfix:after { content: ""; display: table; clear: both; } .u59e0bc90eb53a83adf499263efd76e78 { 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; } .u59e0bc90eb53a83adf499263efd76e78:active , .u59e0bc90eb53a83adf499263efd76e78:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u59e0bc90eb53a83adf499263efd76e78 .centered-text-area { width: 100%; position: relative ; } .u59e0bc90eb53a83adf499263efd76e78 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u59e0bc90eb53a83adf499263efd76e78 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u59e0bc90eb53a83adf499263efd76e78 .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; } .u59e0bc90eb53a83adf499263efd76e78:hover .ctaButton { background-color: #34495E!important; } .u59e0bc90eb53a83adf499263efd76e78 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u59e0bc90eb53a83adf499263efd76e78 .u59e0bc90eb53a83adf499263efd76e78-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u59e0bc90eb53a83adf499263efd76e78:after { content: ""; display: block; clear: both; } READ: Philosophy - Plato Essay Can a superpower be realistically expected to simply ;forgive; and ;heal; terrorists who killed nearly 3,000 people in one single day?

Air pollution  is the introduction of  chemicals,  particulate matter, or  biological materials  that cause harm or discomfort to humans or other living organisms, or cause damage to the  natural environment  or  built environment, into the  atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet  Earth. Stratospheric  ozone depletion  due to air pollution has long been recognized as a threat to human health as well as to the Earths  ecosystems. A substance in the air that can cause harm to humans and the environment is known as an air pollutant. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. [2] Pollutants can be classified as primary or secondary.  Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the  carbon monoxide  gas from a motor vehicle exhaust or sulfur dioxide released from factories. We will write a custom essay sample on Problem Solution or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is  ground level ozone  Ã¢â‚¬â€ one of the many secondary pollutants that make up photochemical smog. Some pollutants may be both primary and secondary: that is, they are both emitted directly and formed from other primary pollutants. About 4 percent of deaths in the United States can be attributed to air pollution, according to the Environmental Science Engineering Program at the Harvard School of Public Health. [citation needed] MAJOR PRIMARY POLLUTANTS PRODUCED BY HUMAN ACTIVITY INCLUDE: * Sulfur oxides  (SOx) especially sulphur dioxide, a chemical compound with the formula SO2. SO2  is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulphur compounds, their combustion generates sulfur dioxide. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain. 2] This is one of the causes for concern over the environmental impact of the use of these fuels as power sources. * Nitrogen oxides  (NOx) especially  nitrogen dioxide  are emitted from high temperature combustion. Can be seen as the brown haze dome above or  plume  downwind of cities. Nitrogen dioxide is the chemical compound with the formula NO2 . It is one of the several nitrogen oxides. This reddish-brown toxic gas has a characteristic sharp, biting odor. NO2  is one of the most prominent air pollutants. * Carbon monoxide   is a colourless, odorless, non-irritating but very poisonous gas. It is a product by  incomplete combustion  of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide. * Carbon dioxide  (CO2) a colourless, odorless, non-toxic  greenhouse gas  associated with  ocean acidification, emitted from sources such as combustion, cement production, and  respiration * Volatile organic compounds   VOCs are an important outdoor air pollutant. In this field they are often divided into the separate categories of methane (CH4) and non-methane (NMVOCs). Methane is an extremely efficient greenhouse gas which contributes to enhanced global warming. Other hydrocarbon VOCs are also significant greenhouse gases via their role in creating ozone and in prolonging the life of methane in the atmosphere, although the effect varies depending on local air quality. Within the NMVOCs, the aromatic compounds benzene, toluene and xylene are suspected carcinogens and may lead to leukemia through prolonged exposure. 1,3-butadiene is another dangerous compound which is often associated with industrial uses. * Particulate matter   Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. In contrast, aerosol refers to particles and the gas together. Sources of particulate matter can be man made or natural. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols. Averaged over the globe, anthropogenic aerosols—those made by human activities—currently account for about 10 percent of the total amount of aerosols in our atmosphere. Increased levels of fine particles in the air are linked to health hazards such as heart disease,[3]altered lung function and lung cancer. * Persistent free radicals  connected to airborne fine particles could cause cardiopulmonary disease. [4][5] * Toxic  metals, such as  lead,  cadmium  and  copper. * Chlorofluorocarbons  (CFCs) harmful to the  ozone layer  emitted from products currently banned from use. * Ammonia  (NH3) emitted from agricultural processes. Ammonia is a compound with the formula NH3. It is normally encountered as a gas with a characteristic pungent odor. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to foodstuffs and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. * Odors  Ã¢â‚¬â€ such as from garbage, sewage, and industrial processes * Radioactive pollutants   produced by  nuclear explosions, war  explosives, and natural processes such as the  radioactive decay  of  radon. SECONDARY POLLUTANTS INCLUDE: Particulate matter formed from gaseous primary pollutants and compounds in photochemical smog. Smog is a kind of air pollution; the word smog is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Modern smog does not usually come from coal but from vehicular and industrial emissions that are acted on in the atmosphere by  ultrav iolet  light from the sun to form secondary pollutants that also combine with the primary emissions to form photochemical smog. * Ground level ozone  (O3) formed from NOx  and VOCs. Ozone (O3) is a key constituent of the troposphere. It is also an important constituent of certain regions of the stratosphere commonly known as the Ozone layer. Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and a constituent of smog. * Peroxyacetyl nitrate  (PAN) similarly formed from NOx  and VOCs. Minor air pollutants include: * A large number of minor  hazardous air pollutants. Some of these are regulated in USA under the  Clean Air Act  and in Europe under the Air Framework Directive. * A variety of  persistent organic pollutants, which can attach to particulate matter. Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and to have potential significant impacts on human health and the environment.
