Law - Assignment Example Conventional dating was the point at which a man asked a lady out a few days before the day they should go dating on the off chance that she was intrigued. The developments made dating increasingly easygoing that it was previously. Nonetheless, the inquiry that bugs numerous individuals is; are hookups fortunate or unfortunate for women’s rights? As indicated by England and Thomas, snare ups are when two individuals go out moving, for motion pictures and later on resign to an increasingly private spot for sexual experiences. Such experiences are helped with a ton of drinking. From the exploration that was completed, a bigger number of men delighted in hookups than ladies. The paces of fulfillment in ladies were low and many were not content with their en counters. A significant number of the men snared with ladies that they had never observed and in the first part of the day, they couldn't recollect their accomplices. Taking to point of view the delicate idea of the ladies feelings, it is then suitable to state that snare ups are not to the greatest advantage of the ladies. Huge numbers of the ladies leave the experiences sincerely wounded and the way that they have not accomplished the planned felling’s makes it all the more baffling for ladies. As much as there is dating, connecting or some other type of communication individuals need to live respectively. This is what is called living together; a living plan that is encouraged by understanding between two gatherings. For the most part this occurs in individuals from the other gender. As indicated by England and Thomas, the expansion in hetero dwelling together has prompted postponed relationships and an increment in separate and caused one of the most critical changes in family life, as we have known it. It is accepted that living together had diminished the submitted that is related with marriage. Marriage used to be the establishment of sexual relations, living respectively among numerous other family related issues. Today individuals are signing up to live respectively without being hitched. They are having kids and in any event, giving themselves names married couples without

Pre-Written Gun Control Sample Essay

Gun Control Sample Essay With regard to the vast amount of gun-related crimes and mass shootings occurring in the USA in the recent years, the issue of gun control has become extremely topical in the society and causes heated debates between the two groups with opposing views of the problem. Thus, articles â€Å"Two States, a Nation Apart on Guns† by Sarah Ferris and Jessica Boehm and â€Å"What to Do About Guns† by Danny Franklin focus on the issue of gun control from slightly different perspectives. Moreover, they place special emphasis on the attitude of Americans to this topic and the measures they advocate for regarding all gun-related crimes. The articles are objective to some extent and offer authors’ viewpoint on the matter based on the all-American study and recent measures taken in various states. The current paper strives to summarize key points represented in the two articles and analyze the authors’ position evident from their pragmatics and theses. In terms of objectivity, the article by Sarah Ferris and Jessica Boehm seems to be more objective than the one by Danny Franklin as the authors present viewpoints of both sides of the argument. Moreover, they offer a deep insight into the issue explaining inherent beliefs of gun-control supporters and the Second Amendment supporters. The authors found their narrative on the examples of Connecticut and Arizona as the two most recent and exemplary states with drastically different attitudes towards guns following similar events. Hence, in both states, mentally ill people perpetrated mass shootings; however, legislators and the public reacted differently afterwards. In Connecticut, legislators passed a law that prohibited the possession and use of â€Å"115 types of semiautomatic firearms† (Ferris Boehm, 2014). In turn, in Arizona, pro-gun organizations lobbied for adoption of laxer laws and for allowing more people possess concealed weapons in public places where they had been previously banned. Moreover, the public was for cancellation or postponement of profound background checks of the majority of the population except for mentally disturbed persons who were deemed to pose danger to public safety. Apparently, such position is explained by an idea that once people are allowed to possess firearms in public places, potential mass shooters would become weary of going on a murdering spree because of a high chance of being killed at once. As one of the pro-gun lobbyists claims,   If I go lock up my gun in the lockbox, the next thing you know the Tucson murdered or Connecticut murdered or Colorado murdered comes along here and looks at that sign and says, ‘Oh, fresh meat’. Because he just watched an honest guy lock up his self-defense. (Ferris Boehm, 2014) Thus, the so-called Newton moment is opposed by fear of repeated murders. The difference in attitudes towards gun control may be explained by inherent differences and prevalent political ideologies dominating in various states. Taking into consideration that Arizona is a predominantly conservative republican state and Connecticut is a blue state, it becomes evident that the two states occupy the opposite ideas about the issue, which is representative of the USA in general. Different states and their respective laws pertaining to harsh or lax gun control measures are impacted either by pro-gun control groups or by the National Rifle Association and the like organizations that blame most gun-related crimes on mentally ill persons and the lack of firearms in households. It seems quite paradoxical to claim the more guns will be freely available to US citizens, the lower the crime rate will be. However, this position is upheld and lobbied in many states, which hampers the introduction of some comprehensive federal gun control measures. The population is divided over the issue of firearms and validity of the Second Amendment in the contemporary world. However, at the same time it seems that no one is ready to fully abandon the right to possess guns instead, offering merely to limit this right. Apparently, one of such suggested limitations concerns enhanced background checks of medical records to detect individuals with mental problems who are supposed to be more likely to use guns for attacks rather than for self-defense.   Danny Franklin focuses on the above-mentioned dispute over the issue of gun control in the society as well, but he pays attention more on the attitude of Americans to the problem and the way this attitude can be changed in order to implement efficient gun control measures. He claims that the major reason why various anti-firearm bills fail consists in the political approach to gun violence. Thus, it should not be handled as â€Å"a political problem to be answered by changing laws. Instead, we need to start looking at guns as a public health problem to be answered by changing minds and habits† (Franklin, 2014). Contrary to the first article that objectively enlists facts and arguments of both sides of the argument, the author of the second article takes a certain position and suggests a strategic plan that he calls â€Å"a public health approach† (Franklin, 2014). In fact, this schematic guide is aimed at changing attitude towards the issue of gun control in the USA, wh ich would subsequently lead to a decline in the amount of firearms sold, bought, and used in the country. The main idea of the author is that the framing of the issue has to be amended by pro-gun control activists with a view to efficiently opposing lobbying of lax measures by the NRA and other similar groups. Most offered gun control measures fail because of the strong propaganda by such organizations and their influence on lawmakers. Therefore, the author emphasizes the necessity of adopting some countermeasures to this propaganda and advocates for developing ways to cause a shift in the Americans’ perception of guns and safety. Although the two analyzed articles concern the same topical issue, they are different in terms of the information presentation mode and objectivity. While the first article simply contains some key arguments for both sides of the debate, the second article takes an evidently pro-gun control position and advocates for the implementation of the public health approach aimed at changing the attitude of Americans towards firearms. Despite some differences, both articles are similar in terms of emphasizing topicality of the issue of gun control and attempting to draw readers’ attention to the problem with a view to developing an effective solution that would decrease the rate of gun-related crimes and prevent mass shooting tragedies in the future.

How Far the Weimar Constitution Can Be Described as...

How Far the Weimar Constitution Can Be Described as Creating an Effective Democracy For the first time in the history of Germany, the state was a democratic republic. The constitution was something of a fragile experiment, a guinea pig. Theoretically speaking, the Weimar Constitution could be described as the most democratic constitution the world has ever laid eyes upon, in practice, things were not as clear. Germany was to be a â€Å"Federal State,† with each â€Å"Lander,† (state) retaining limited control over local affairs. This recognised local differences within Germany, with each Lander being represented in the Reichstrat. Effectively small states had as much influence as bigger states. This†¦show more content†¦So even extremists could be represented, and thus extremists are given a say in the running of the country albeit limited to the size of the extremists. Democracy is rule by the people, which the Weimar Constitution included extremists within. Plebescites were relatively common, which are effective referenda, giving the German public direct choice on an issue, thus being ultra democratic, with the German people being allowed to make decisions by themselves as opposed to simply having elected representatives making decisions on their behalf. The Bill of Rights was effectively made for German workers. Trade unions were instituted to organise a minimum wage. The consideration of workers, in a previously elite class system, reflects new democratic intentions, giving everybody an equal footing. For the first time in German history everybody had freedom of religion and speech, regardless of beliefs. This is incredibly democratic as it means that all people were allowed to express themselves truthfully, no matter how extreme or unpopular their opinions were. Everyone was considered equal. The president was politically accountable, being voted by the people every 7 years. The idea was that the president was not in office long enough to establish a dictatorship; enforcing the foundations of democracy (i.e. that a democracy is not a dictatorship.)

John Adams And Abraham Lincoln - 1976 Words

Despite the disparity in popularity ratings between the two presidents, John Adams and Abraham Lincoln are both indispensible figures in American history. In times of crisis, both of these men made big, consequential decisions to keep the country from falling apart. However, while Lincoln is commemorated for abolishing slavery and leading the Union in war, John Adams is remembered for the mistakes of his presidency—the Alien and Sedition Acts he issued that took away certain constitutional rights endowed to the American people. Both presidents thought they were doing what was necessary at the time to keep the United States from falling apart, but the contrasting approaches they used left opposite impressions. This can be contributed to the†¦show more content†¦Justice is an important concept to John; one of his core beliefs. Right before the war, John’s firm belief in justice poses a problem for him as the colonies unrest continues to grow. As he said to Abigai l â€Å"I am for the law. And yet in whom is the power of that law vested? The King† (Hooper). He wants to rely on the law for justice but the law is made by the king to take away their rights, an action as unjust as it can get. This dilemma is what drives him to represent Massachusetts in the Continental Congress and what sets him up for being apart of American history. John, as depicted several times throughout the series, is abrasive, offensive, and vain, and this makes him an unpopular person. During the Continental Congress, despite the fact that most people agree with John about standing against the British, they oppose him in votes because of how insulting he is. In France, John is unable to adapt to the culture shock. He has no regard for French culture, he struggles to fit in, and he’s so straightforward about what he wants he comes off as rude and disagreeable so, even though his intentions are good, he harms more than helps. His obnoxious demeanor contributes to the reason he was so unpopular with everyone but Adams actually did a lot to progress America. John’s part in the political aspect of America was most of the time very productive to

Elastic Modulus of Concrete Containing - Free Samples to Students

Question: Discuss about the Elastic Modulus of Concrete Containing. Answer: Introduction: Pandian (2013) stated that fly ash is such a waste material which is formed as by the product of the coal combustion process. Yao et al. (2015) argued that it is used as Supplementary Cement Material (SCM) within the making of Portland cement concrete. It has wide range of physical as well as chemical properties as similar to the cement. In some of the marketplace, fly ash is a cost- effective substitute for the Portland cement. The research study is based on analyzing the content of the Fly ash and its specific uses. Selection of the fly ash is focused on its properties for utilizing it in effective way. Its selection is based on monitoring the fineness as well as loss on explosion of the fly ash. Literature review is conducted for reviewing the uses, benefits and applications of fly ash. Aims and objectives are also determined for identifying the purpose of this study. Experimental set up shows the content of fly ash and the results are analyzed to determine the research outcomes. Franus, Wiatros-Motyka and Wdowin (2015) determined that fly ash is used as prime material into the blocks and bricks and its one of the important application is PCC pavement. It is used as larger quantity of concrete and substitutes the fly ash provides of economic benefits. It is used for paving of roads in addition to mine fills. Ghosh et al. (2015) analyzed that more than 50 percent of concrete is placed in US which contains fly ash. The rate of quantity is based on type of fly ash; it is observed that Class F fly ash is being used by the side of dosages of 15-25 percent by mass of the cementitious material and then Class C fly ash is at rate of nearly 15-40 percent. Class F is a type of fly ash that consists of particles which is covered in melted glass, it lessens risk of expansion. Garrabrants et al. (2014) concluded that Class F consists of lower quantity of calcium fly ashes with a content of carbon of fewer than 5%; however it consists of 10%. Class C fly ash is opposed to development from the chemical attack; it consists of high percentage of the calcium oxide. It is fundamentally used for the structural concrete. Yao et al. (2015) determined that Class C fly ash is composed of high quantity of the calcium fly ash with a substance of carbon of fewer than percentage of 2. Franus et al. (2015) cited tha t fly ash is being identified as environmental friendly product as it is byproduct and inferior embodied energy. del Valle-Zermeno et al. (2013) concluded that fly ash needs of less water as compared to Portland Cement and it is simple to utilize in the chilly climate. The advantages of fly ash consist of cold weather resistance, substitute for the Portland cement, produce denser concrete and reduce heat of the hydration. Ramezanianpour (2013) stated that fly ash also produces of lower water for comparable slumps when it is contrasted to no fly ash mixtures. Effect of fly ash on fresh concrete Fly ash expands the workability of concrete. It refers to easily handle, place and finish of fresh concrete. Zhao et al. (2015) determined that concrete of fly ash is more practicable as compared to plain cement concrete at correspondent slump. For the slump, less water is required, and then the concrete gets cohesive and there is decrease into occurrence of segregation. There is an increase into occurrence of total amount of the fines and produces concrete more practicable and compaction. Anastasiou, Filikas and Stefanidou (2014) analyzed that fly ash consists of 30 percent of greater volume as compared to cement. The concrete of fly ash is approachable to the vibration. Into larger concrete, 3.05*3.05*3.05 m, the highest temperature is reached into middle of concrete block was to be 54 degree Celsius when the starting temperature is 19 degree Celsius. Sar?demir (2014) investigated that the temperature of higher volume of the fly ash concrete be 15-25 degree Celsius which is less as contrasted to reference concrete with no fly ash. It is an advantage of fly ash where both thermal gradients with stress are issues. Sar?demir and Billir (2016) mentioned that strength of higher volume of concrete of fly ash keeps increased due to pozzolanic reaction of the fly ash. It makes stronger bond between cement paste as well as aggregate. Concrete cores are taken from the experimental block which is made of mixed higher volume of fly ash concrete with strength of 110 MPa. It is a longer term gain of strength of this kind of concrete. Bingol and Tohumcu (2013) argued that concrete of higher volume of fly ash combined of 55 percent of Class F fly ash, one crude and finer fly ash. Strength development of fly ash of concrete with blended cements is faster as compared to concrete of underground fly ash. Improvement of flow ability, reduction of hydration temperature an delay in setting time of the concrete of fly ash are considered as main factors for placement of concrete. Dhiyaneshwaran et al. (2013) analyzed that fly ash is commonly used as partial replacement of Portland cement which is used to produce of concrete. The rate of replacement is run between 20-30 percent while sometimes it becomes higher. Shafigh et al. (2013) observed that fly ash is reacted with lime as pozzolan into the cement as it hydrates, produces durable binder which holds of concrete. The result is that concrete is made with fly ash is stronger in addition to resilient. Fly ash is mainly used into the infrastructure project such as for construction of road, highways as well as bridges. Choi et al. (2014) concluded that it is used to overcome the issues such as alkali silica reaction that occurs when concrete declines are before time due to issues with combined quality. It is mainly used to compact with the issues. Uses of the fly ash results into positive environmental impact because of it conserves of landfill spaces, reduction of consumption of energy as well as water (Chinda prasirt Chalee 2014). It helps to reduce of greenhouse gases. Fly ash dislocates the construction of Portland cement that emits one ton of carbon dioxide for each ton of cement creation. For each ton of use of fly ash, emission of carbon dioxide is reduced by one ton. Nie et al. (2015) investigated that while the generated fly ash is utilized in production of concrete, then reduction of emission of carbon dioxide is equivalent to eliminate 25 percentage of the globes total vehicles. Research Question, Aim/Objectives and Sub-goals Following are the research questions for the study: What does fly ash do into concrete? What are the effects of fly ash on fresh along with hardened concrete? How is fly ash used? The aim of this research study is to test concrete based on its effects, strength as well as durable to make sure that it meets with requirement to standard concrete. The goal is to meet with the objectives and complete the plan within scheduled time. Following are the objectives of the research study: To examine the concrete of the fly ash To find out the effects of the fly ash on fresh in addition to hardened concrete To identify with the use of fly ash into the concrete Theoretical Content/Methodology In this particular study, mix concrete is added with the fine mineral dust. Ordinary concrete is mixed with Portland cement, coarse aggregate with water and sand is contrasted with improved concrete. It is seen that concrete is being tested based on some factors such as strength, durability in addition to workability. Slump test is conducted for calculating the slump value. It is done on smooth and level surface (Arezoumandi Volz 2013). After this test, compaction test is done to calculate compaction index of the concrete. Using the simple replacement method, Portland cement is restored by fly ash. In this particular process, early strength of the concrete is low and high strength is being developed for 56-90 days. At the early on ages, the fly ash exhibits of cement value (Balakrishnan Awal 2014). At the later age, liberated lime is resulted from hydration of the cement which reacts with fly ash. It adds to higher strength to concrete. This particular method utilizes of mass concr ete wherever beginning strength of the concrete has lesser important as contrasted to reduction of rise into temperature. As the Portland pozzolana cement is a finished product, therefore it does not require of quality check for the fly ash at the concrete production time (Chindaprasirt Chalee 2014). Into this method, proportion of fly ash as well as cement is fixed and it is limited to proportion of the fly ash into concrete mixes. Addition method is that method where fly ash is added to concrete with reduction of quantity of Portland cement (Liu et al. 2016). It results into increase of cementitious content of concrete and increases strength of ages of concrete mass. Bingol and Tohumcu (2013) analyzed that modified replacement method is used to formulate strength of the fly ash concrete which is equivalent to strength of the control mix at the untimely ages of between 3-28 days. In this chosen method, fly ash is being utilized by replacement part of the usual Portland cement by the mass along with making modifications into amount of fine aggregate in addition to water. With use of this method, mixture of concrete is designed which have total weight of Portland cement (Ramezanianpour 2014). In the method, amount of cementitious materials is put superior than the amount of the cement in the control mix to compensate reduction into earlier strength. According to Zhao (2015), mixing method has an influence on the concrete mixes with fresh states. Mixing method is finalized for this research study on the concrete of the fly ash. It is a two stage mixing which outcomes pleased the researcher while fresh along with hardened properties are measured. The main purpose of use of fly ash into cement concrete applications is to provide of durable concrete at low cost. Experimental Set-up In this particular research study, multistage of the mixing series with different time of agitation for every stages are adopted. There are mixed proportions of M50, M35 as well a M20 grade of the fly ash concrete with a percentage of 40, 50 as well as 60 percentage of th cement replacement levels (Sar?demir Billir 2016). The properties of the fresh as well as hardened states of the concrete is mixture is produced by various types of mixing methods such as M50, M35 as well as M20 of the grade identified mixes. The comprehensive strength of results of the mixes is 14, 28 as well as 56 days which are produced by various types of mixing methods such as M50, M35 in addition to M20. (Garrabrants et al. 2014). The selected parameters for analyzing the properties of the fly ash are surface area, comprehensive strength, soundness, chlorides and silica. All the identified parameters are within the permissible limits. The cement fly ash blends are rated as 10-50 percent by the weight of the cement which is step of 10 percent. There are various important factors which are significantly considered for doing the study such as consistency, setting of the time, workability and lastly the comprehensive strength (del Valle-Zermeno et al. 2013). In this study, M20 grade has normal mix with a concrete mix proportion of 1:15:3 by the volume and the ratio of the water cement of about to 0.5 is to be taken. The fly ash is to be unified into the cement at rate of approximately 5-25 percent by the weight of cement with step of percentage of 5. Results, Outcome and Relevance Both workability as well as strength of concrete is increased due to dissolving effects of the fine materials dust. It is analyzed that slump losses for mixture of concrete with fine materials dust is reduced than other mixture. There is slightly fewer strength of concrete at early age whereas in some degree, it shows higher strength for 28 days (Anastasiou, Filikas Stefanidou 2014). It is helpful for durability of concrete of fly ash. It is observed that the fly ash is being blended into cement at a rate of 10-50 percent by weight of the cement. The cement of the fly ash is blended and tested base on some of the properties such as consistency, setting of time, workability along with compressive strength. Into the test sample of the concrete, it is filled with size of 15*15*15 cm and then top of the mould is being strike off. The researcher concluded that fly ash is being added in place of the cement into concrete of 6 percentage which starts from 0 percent. It is then raised for few days and then after 28 days, it is increased equally (Bingol Tohumcu 2013). After storage for 90days, concrete remains 10 percent of fly ash which gains strength of 6 percent higher than concrete with no addition of ordinary Portland cement. When the fly ash blends of more than 10 percentage of fly ash, then both strength development with final strength is reduced with further added of fly ash. Activities Expected Start Date Milestone 1: Completion of project preparation Thu 11/23/17 Milestone 2: Completion of research methodology Tue 12/12/17 Milestone 3: Completion of project documentation Thu 1/4/18 Figure 1: Gantt chart (Source: Created by author) Conclusions It is concluded that fly ash is most advantageous waste materials. It is mainly used into the construction project and not only helps into disposal but also adds strength as well as durability into fly ash. It is also studied so as to fly ash is used as concrete of cement into minor amount as additives. It is a solid waster that is used for many purposes. Basically, it is used as raw material into Portland cement as leads to saving of cement. However, it is an environmental consistent method to dispose of fly ash. The researcher also concluded that power plant waste is used into concrete as temporary replacement for the cement as well as mixtures. Fly ash helps in increasing the strength over time and it continues to associate with the free lime. There is upgraded into density and for a long time of pozzolanic action of the fly ash. It is resulted into fewer channels as well as decrease of the permeability. It is analyzed that fly ash is combined with alkalis from the cement which co mbined with silica from the aggregates and prevented from descriptive expansion. The pozzolanic reaction between the fly ash as well as lime is generated of less heat which results into reducing the thermal cracking when fly ash is used for replacement of Portland cement.

Promoting Behavior Change among Teenagers

Introduction Substance abuse among teenagers is increasingly becoming a common phenomenon in the community. Substance abuse involves the use of drugs such as alcohol, tobacco and marijuana. Research on the use of drugs among teenagers indicates that majority begin using the drugs as early as the age of 9 years (Fisher and Harrison 43). The use of drugs among teenagers is responsible for the poor academic performance among those who use them. Advertising We will write a custom essay sample on Promoting Behavior Change among Teenagers specifically for you for only $16.05 $11/page Learn More Besides, substance abuse has led to an increase in diseases such as lung cancer among teenagers (Fisher and Harrison 56). The efforts made by the government and the parents to address this problem have yielded little results. It is against this backdrop that I intend to organize a social event that aims at sensitizing teenagers on the effects of substance abuse. The Eve nt The Participants The event will be held on 25th of January 2011 at the community’s social hall. The preparations will begin a day earlier. The preparations will involve advertising the event through posters and decorating the venue (Kilkenny 78). The event will start at 9: 30 am and end at 5:30 pm. The speakers will include parents, teenagers and community health officers. The speakers will be asked to volunteer and offer their advice for free. All participants will be asked to carry packed foodstuffs and drinks. However, the guest speakers will be given free food and drinks. Apart from the education, there will be entertainment activities such as singing competitions. The entertainers will be the participating teenagers who have a talent in singing and can volunteer to perform within a short notice. The Agenda of the Event The theme of the event will be â€Å"promoting behavior change through social networks†. The event aims at persuading teenagers to stop substa nce abuse in the neighborhood. The first step will involve sensitizing the teenagers on the negative effects of substance abuse. This will be followed by an explanation on how to cope with the problem of substance abuse. This aims at helping those who are already involved in substance abuse to manage their conditions. Finally, the teenagers will be educated on how to avoid the use of drugs. The education will focus on how teenagers can use social networks such as twitter and facebook to share information on the dangers of substance abuse and how to avoid or cope with it.Advertising Looking for essay on education?

criminology1 essays And the other child grows up to be somebody who just loves to burn An excerpt of this poem paints a picture of two brothers, John and Robert Wideman, leading different lives. Robert Wideman, embraced a path common for black men during that era; a life of crime, glamour, and drugs. Quietly sitting in jail, he reminisces deeply about his troubled past and the consequences of the future that now haunts him. John, on the other hand, chose the path less taken by those living in the same world as he did and in due time become a successful professor at a University. How did two people from the same origin, living in similar environments, and raised by a caring family choose such different paths? Some might explain the cause to be risk factors, learned behavior, or missed opportunities. When explaining criminal behavior, it is inevitable to identify sociological, behavioral, and psychological problems as causes of crime. John and Robert always dreamed about running away from the poverty embracing their community. Even though they shared the same dream, each considered different means of achieving this dream. John determined early on that to get ahead, to make something of myself, college had seemed a logical, necessary step; my exile, my flight from home began with good grades, with good English (27). In order for John to climb the social status, he realized that his only ticket out of poverty and his community is through a good education. Status must be earned through hard work and determination. Robert is just the opposite of John. Early on, Robert acknowledged that school and sports could not satisfy the glamour that Robert so much desired? Unlike John who dis ...

A Comparison of Antigones and Ismenes Reactions to Grief in Antigone by Sophocles

A Comparison of Antigone's and Ismene's Reactions to Grief in Antigone by Sophocles Response Paper to Antigone The tale of Antigone is one of the oldest pieces of literature that is still being studied today. The play is able to explore the psychology of many different characters as they are all forced to deal with the death Polyneices. While the differences between how Antigone, Haimon, and Creon respond to the situation may be widely discussed, another interesting relationship to analyze in the text is that between Antigone and Ismene. Both sisters experience a tragedy as their brothers kill each other, yet their responses are quite different. Antigone’s response to the grief is to focus on the injustice of the situation and risk herself to set things right, while Ismene is filled with sadness, yet fears the ramifications of breaking the law. Both responses are results of love, yet the specifics of each case allow a deeper look into the psychology of these characters. When reading and discussing the play of Antigone, Antigone herself is most often seen as the heroin. However, it could be argued that Antigone is the reason for the tragedy. If Antigone had expressed her grief with Haimon, it is possible that he could have convinced his father to lift the law against burying Polyneices body. Also, her rash decision to kill herself leads to the death of both Haimon and the queen as they are filled with grief. After thinking through the different endings that could have occurred if Antigone had responded calmer, it is reasonable to conclude that Antigone’s plan of rebellion was not the most practical response. Ismene, on the other hand, responds with grief but no action. It could be argued that this is a more practical response as it prevents any further harm, yet with Ismene’s response nothing is really fixed, it is all merely pushed aside as if it did not happen. After analyzing the practicality of the girls’ responses, the question of morality is raised. Was Antigone doing the right thing, standing up for her family and offering herself as a sacrifice? Or was Ismene correct in avoiding further conflict and simply grieving for the loss of her brother and his honor? This is a very difficult thing to analyze as the grief in this situation is almost unfathomable. It may be most reasonable to argue that neither girl was in the right mindset to make a moral, practical decision. They have just learned that their brothers have killed each other and one will die with honor, while the other may not. Thinking about this situation, it becomes clear that neither girl responded ethically nor practically, but they both responded emotionally according to their own personalities. The play Antigone by Sophocles includes multiple complex situations and relationships, and that of Antigone and her sister Ismene is one of the most intriguing. Watching these girls deal with the pain of losing their brothers and then deal with the pain of losing each other in disagreement over the situation makes the tragedy more powerful. Sophocles is able to include human nature in this situation as both sisters behave impractically and unethically. This is seen often in life as well as emotions overcome logic and may lead to even more tragic situations as those that occur in Antigone.

Impact and Outcomes of Effectual Risk Based Planning Applications Essay

Impact and Outcomes of Effectual Risk Based Planning Applications - Essay Example Broad policy alternatives and a process of restructuring the existing practices have to be adopted in order to overcome the present impasse. I advocate a local level policy shift rather than a Federal level overhaul. Public administration consists of non-profit governmental institutions that form the bulk of a country’s administrative system. The process of planning at institutional level might require a cohesive and articulate strategy with a particular focus on existing inadequacies of the system. Non-profit public sector institutions operate on the principle of public welfare at the grassroots. However, there is an imbalance in these institutions when it comes to efficient management processes and institutional structures. Ill-defined targets often serve as hurdles that have to be surmounted even before the project is started. Project risk perception and management is another such area in which both leadership and intelligence are lacking. It is imperative to question the unprivileged immunity from public scrutiny that is almost taken for granted by local level administrators whose attitudes have, over the years, been conducive to producing negative outcomes in the sphere of public adm inistration. Causal factors include a host of fallacious assumptions too. Risk has a variety of meanings and senses that defy our articulation or assessment capabilities. Therefore in risk-based planning process there can be no perfection or certainty in determining a set of variables that impact on the planning process and the eventual outcomes. Both endogenous and exogenous variables impact on these outcomes, irrespective of our hypothetical presumptions on what shape those outcomes should take. Community or county level administration might seek to exert pressure on Federal bodies to facilitate legislation that cohort principles of public choice theory. For instance the Risk-Based Homeland Security Grants Act

The U.S cultures and business perspectives Essay

The U.S cultures and business perspectives - Essay Example Just like the U.S.A, Brazil is a melting pot of nationalities due to long periods of slavery and European domination. The country has about 190 million people, whereby 50% of the people are white. Majority of the Brazilian people are Catholics and speak Portuguese as a national language. Bananas are the staple food in Brazil. Bananas are also grown in America, Texas. The Brazilians prefer to deal with companies, rather than individuals when doing business. The people have a close adherence to business etiquette like the Americans. The Saudi Arabians are primarily Arabs and Muslims. Greetings are very formal in Saudi Arabia. On the other hand, people in the U.S don’t take too much time greeting each other. Women in Saudi Arabia dress in abayas (cloths that cover the entire body except the face and hands). The manner of doing business in Saudi Arabia is largely similar to that of the U.S.A in terms of etiquette and communication style. The country is the Middle East’s lar gest trading partner of the U.K. Dressing in suits and ties is a similarity for Saudi and American businessmen.  Territorial-wise, Russia is the largest country in the world. With Russian serving as the main language, the country has over 190 ethnic groups. Christianity, Islam and Tengrism are the primary religions of Russia. The Russians eat unique foods such as Borshch, Caviar and Pirozhkis. The Russians value time keeping highly when doing business. The ceremonial practice of receiving and exchanging business cards is taken seriously in Russia.

Alienation in As I Lay Dying, William Faulkner Essay -- As I Lay Dying

William Faulkner is an American novelist whose major work is As I Lay Dying. Faulkner gave each of his characters traits that are expressed throughout the story.   The reader is introduced to each character through their detailed and descriptive character traits.   We are able to delve into the character's mind and see their personal and distinct traits. He did not tell us anything about the characters, but he takes us into the mind of each character to analyze what we see there. Even though these characters lead parallel lives we can see the total alienation and breakdown of the relationships between each other.   Darl, Jewel, and Anse possess character traits that contribute to or cause the breakdown of their relationship.   Ã‚  Ã‚   Anse Bundren is a poor farmer, who was married to Addie for more than thirty years. He is lazy and selfish and relies greatly on his family and friends. Anse’s selfishness is what separates him from his two sons-Darl and Jewel. For example, the journey to Jefferson, to bury his dead wife was a promise he made to Addie, but his continued perseverance to better himself reveals his true selfishness. Despite the trials along the way and Addie’s body decomposing and attracting buzzards he is only concerned with getting to Jefferson to buy his new teeth. He uses Addie’s death to accomplish his own selfish motives. After Addie’s death Anse says, â€Å"But now I can get them teeth. That will be a comfort.† (Faulkner 28). The only reason Anse is carrying out with the journey is to get his new teeth. He further shows his selfishness when their mules are drowned in the flood. He makes an arrangement with a kinsman to trade Cash’s eight doll ars and Jewel’s beloved horse for a new team of mules. Thirdly, Anse is so concern... ...ls seperate from each other despite everything they share together. Faulkner shows us that with the death of Addie, the flood, fire, and the decomposing of flesh that should have brought them closer together, they are too self-absorbed in themselves to ever get close to each other.

Pop Music Has It Gone Too Far Essay

Has Pop music gone too far some might say yes some might say no but to some extent everyone would agree but how can you judge this by standard of the generation and how the artist changed it as well as how you would think the next generation would react. hen we began the course it started with rock and rollers wearing suits and dancing with a 1-2 step then coming to 2013 which Ithink the second teen idol era such as Justin Bieber or Katy Perry or even worse the Kardashians but even now compare them to the likes of Fabian teen idols of the late 50s-60s who are taking the rolls of Elvis and such should be noted than filming of Elvis from the waist down was prohibited at a time then to half naked women for the sake of getting a gold record and a couple of bucks but then there was jim morrison waving around his penis on stage but it can be said he was under influence of several things. But all in all I Say that yes it has gotten too far . Pop music can be said to be always changing because the change from R&B to hip hop did not happen without a huge change like rock and roll and san francisco but when you say something is extreme the next generation will take it as the norm say when 80s rock and roll started making sex related music videos which was considered ridiculous today its everywhere my cousin who was listening to songs like stronger or E. however her mom had no problem . One of the biggest thing I Seen arise is that it injected itself into our culture just like a virus from well dressed clean cut to leather pants and jackets and crazy cuts but it began with the beatles who simply got long hair. Or when KIss stated wearing leather and make up the youth followed proving that it was no longer anti-culture it was culture and changing america for better or worse. Another thing that crossed my mind is that good is bad and bad is good when the rolling stones crossed this path they set a whole world of problems but how far can you go for record sales once it was love, peace and tolerance then it turned to sex drugs and rock and roll while the singers who were in tune were dismissed while screamers were considered the best. But some may not think this is a big deal, it is pop music but I Would think death would change one’s mind. Jimi Hendrix one of the best guitarists died due to â€Å"misadventure† aka he overdosed as well as jim morrison taking their own lives the best of the san francisco style dead, pop music took these â€Å"tortured† souls but it can be said that they had it coming to them how about the fans, ordinary people for example say Altamont Free Concert what could go wrong Free concert with world famous acts what could go wrong. Drugs and alcohol can. The rolling stones here tried to skip the police and decided that they can do whatever they wanted , they were a pop artist group of course, so they decided to hire the hells Angels and with the drugs and fight music a brawl broke out between a fan and to members which ended with the death of Meredith Hunter who was stabbed to death by the security personnel and it was caught on tape. Or when the prince of darkness decided to write a song about suicide (suicide solution) a teenaged John McCollum decided to kill himself . he lyrics went†Where to hide, suicide is the only way out Don’t you know what it’s really about Wine is fine but whiskey’s quicker Suicide is slow with liquor Take a bottle, drown your sorrows Then it floods away tomorrows† this song at the least suggests suicide if not promoting it . Being bad may bring in platinum records and #1 hits but when people start dying bad is not good any more it’s bad. Rock and roll was once full of well dressed mannered people the Beatles be a good example and early on their lyrics meant well elvis sang about love and moondogs then Jimi hendrixs start humping his guitar on fire then the who started breaking equipment , The rolling stones started shooting heroin on stage, ozzy osbourne bit the heads off a bat and Jim morrison exposed himself and I doubt all they sung about was love me do and twist and shout the lyrics esuculated from â€Å"in benefit of mr. ite† to Prince saying incest is ok or when twisted sister said to shoot them down with a _______ gun then Venom advising â€Å"Welcome to my sacrifice Plunge the dagger in her breast† then ice-t saying to kill police or when blackie lawless is acting out sex with a saw . The lyrics are what sells albums Eminem and 2pac both are one of the most successful rap artists ever and yet there lyrics call for killing cops homophobia and songs against women. In a song Eminem or marshall mathers once said that there would be the same amounts of drug addicts and murders without me something I Doubt. The more famous the artist the more influence they have charles manson said that the Beatles were prophets . Going back in time there was a time when music was a time where music was an extra part of life which was recreational and now we hang on every last word of our favorite artist say swag which was reintroduced by T.  I jay-y as well as justin bieber and it is still around and don’t forget YOLO which was created by drake but it seems though as it is dying out but hats, shirts and bracelets were made and this is where it begins to push the limits when people live their live based upon these word which in a way is no different than Charles Manson. Or when Wiz Khalifa is so open about his weed addiction and so many of my former friends started because of him or even earlier when Dr. dre started and when people take pills because eminem did it or acid because the beatles were cool. hen people say pop music artist does this it becomes a religion like following like how a good christian would follow the teachings of jesus they are following the ideals of pop stars and became the center of everything as John Lennon once said†We’re more popular than Jesus now† or when Kendrick Lamar Says†Depending on what you expecting, I’m sure it’s bigger than your religion†After this course I’m wondering where is the responsibility of these Musicians who control the public when are they saying not to listen to them but they want to be heard so if you do go to F.  Y. E and pick up a Marshall mathers lp the responsibility is given to the parents as there is a little text box saying parental advi sory for us to have to worry about those things itself proves that Pop music has gone too far as you wouldn’t let your child listen to Eminem or Ozzy And you would not let your parents hear you listening to them I think thats the limit when it starts to on Prentice Hall, 2006.

Facts About the Solar System

Welcome to the solar system! This is where youll find the Sun, the planets, and humanitys sole home in the Milky Way Galaxy. It contains planets, moons, comets, asteroids, one star, and worlds with ring systems. Although astronomers and skygazers have observed other solar system objects in the sky since the dawn of human history, it has only been in the past half-century that theyve been able to explore them more directly with spacecraft. Historical Views of the Solar System Long before astronomers could use telescopes to look at objects in the sky, people thought that the planets were simply wandering stars. They had no concept of an organized system of worlds orbiting the Sun. All they knew were that some objects followed regular paths against the backdrop of the stars. At first, they thought these things were gods or some other supernatural beings. Then, they decided that those motions had some effect on human lives. With the advent of scientific observations of the sky, those ideas vanished.   The first astronomer to look at another planet with a telescope was Galileo Galilei. His observations changed humanitys view of our place in space. Soon, many other men and women were studying the planets, their moons, asteroids, and comets with scientific interest. Today that continues, and there are currently spacecraft doing many solar system studies. So, what else have astronomers and planetary scientists learned about the solar system?   Solar System Insights A journey through the solar system introduces us to the Sun, which is our nearest star. It contains an amazing 99.8 percent of the mass of the solar system. The planet Jupiter is the next most-massive object and it comprises two and a half times the mass of all the other planets combined. The four inner planets—tiny, cratered Mercury, cloud-shrouded Venus (sometimes called Earths Twin), temperate and watery Earth (our home), and reddish Mars—are called the terrestrial or rocky planets. Jupiter, ringed Saturn, mysterious blue Uranus, and distant Neptune  are called gas giants. Uranus and Neptune are so cold and contain a great deal of icy material, and are often called the ice giants.   The solar system has five known dwarf planets. They are called Pluto, Ceres, Haumea, Makemake, and Eris. The New Horizons mission explored Pluto on July 14, 2015, and is on its way out to visit a small object called 2014 MU69. At least one and possibly two other dwarf planets exist in the outer reaches of the solar system, although we do not have detailed images of them. There are probably at least 200 more dwarf planets in a region of the solar system called the Kuiper Belt (Pronounced KYE-per Belt.) The Kuiper Belt extends out from the orbit of Neptune and is the realm of the most distant worlds known to exist in the solar system. It is very distant and its objects are likely icy and frozen. The outermost region of the solar system is called the Oort Cloud. It probably has no large worlds but does contain chunks of ice that become comets when they orbit very close to the Sun. The Asteroid Belt is a region of space that lies between Mars and Jupiter. It is populated with chunks of rocks ranging from small boulders up to the size of a big city. These asteroids are left over from the formation of the planets.   There are moons throughout the solar system. The only planets that do NOT have moons are Mercury and Venus. Earth has one, Mars has two, Jupiter has dozens, as do Saturn, Uranus, and Neptune. Some of the moons of the outer solar system are frozen worlds with watery oceans beneath the ice on their surfaces.   The only planets with rings that we know of are Jupiter, Saturn, Uranus, and Neptune. However, at least one asteroid called Chariklo also has a ring and planetary scientists recently discovered a tenuous ring around the dwarf planet Haumea.   The Origin and Evolution of the Solar System Everything that astronomers learn about solar system bodies helps them understand the origin and evolution of the Sun and planets. We know they  formed about 4.5 billion years ago. Their birthplace was a cloud of gas and dust that slowly contracted to make the Sun, followed by the planets. The comets and asteroids are often considered the leftovers of the birth of the planets.   What astronomers know about the Sun tells us that it will not last forever. Some five billion years from now, it will expand and engulf some of the planets. Eventually, it will shrink down, leaving behind a very changed solar system from the one we know of today.
