Overpopulatio in the United States - Essay Example This makes the US one of the fastest growing nations in the line of industrialized nations in the world. This overpopulation has caused various problems in the country, such as scarcity of resources, environmental issues, and economic consequences. Moreover, the problem of overcrowding also presents lack of education, and other issues which might cause troubles for the humanity. It is anticipated that by the year 2050, the population of the nation will be increased by around 130 million people, which is nearly equivalent to the addition of four more states the size of California. This study presents a detailed research on the topic of overpopulation in the United States. It undertakes to consult various resources, publications and databases to obtain information regarding the subject at hand. The causes of overpopulation are considered along with an elaborated discussion on the effects and consequences of the issue. The concept of overpopulation in not new to the current world and has been debated upon much by the researchers and authors. The definition of the term â€Å"overpopulation† is generally given by the writers as a commonly adverse and detrimental context in which the number of organisms goes beyond carrying capacity of its environment (Ian, 2007). This terminology generally pertains to the association between the two variables: environment and human population. The environment can either refer to a small geographical area or entire earth. During the past few years, the population in the United States has increased by more than double. It is said that if the population of the world in the coming century is multiplied by the same amount, there shall be more than one billion people around the globe. This increasing population, in turn, affects many features which include the negative contribution to the beauty of land, forests, environment and the entire ecosystem. Then, the social problems such as increasing attention in schools and lack of teachers

Safety with Armed Guards Patrolling School

Safety with Armed Guards Patrolling School Introduction: There is lots of schools that do not have as much security to protect students and teachers from violence.Having guards on school campus do help but what if the school was on a lockdown because of a shooting on campus. What is the guard going to do? Go up to him like nothing? No. What we need are armed guards. Armed guards will be able to stop the shooting and save peoples lives. Prevention and mitigation. Graves has used U.S. Justice Department grants for classroom door locks that can be secured from inside, plus video cameras and electronic locks for outer entrances. There are a lot of wonderful fire prevention approaches, Graves notes. Wouldnt it be great if we could have the same consideration given to other kinds of threats? Preparedness. Because 95 percent of emergency situations requiring lockdowns happen outside of school buildings, Lincoln County schools have two kinds of lockdown. A partial lockdown occurs when you bring everybody inside and instruction continues. Does your school have a plan for getting students back indoors quickly? Graves asks. We call it reverse evacuation. And you have to announce it because there are almost always some kids outside. A complete lockdown is what happened in Newtown, with school employees working quickly to make sure children were tucked out of sight. Response. During spring break, Lincoln County schools invite police officers onto each school campus for active shooter training, during which they learn the layouts of buildings and practice stopping an assault. Its a useful exercise that, luckily for Lincoln County, has never been tested. Recovery. During this period, the entire school community steps in to provide support. Graves experienced this phase firsthand when she was invited to Newtown after the tragedy there. She visited memorials, hugged people, cried with them and listened as one local man told her that even the shooter was one of ours and we failed him. Schools are still by far the safest places in America. But the events in Newtown have swayed public opinion in ways that earlier shootings did not, and the AFT stands with President Obama, who said in his second inaugural address that our journey is not complete until all our children, from the streets of Detroit to the hills of Appalachia to the quiet lanes of Newtown, know that they are cared for, and cherished, and always safe from harm. Knowing that our schools will never be safe as long as it remains easy for criminals or the mentally ill to acquire guns. AFT president Randi Weingarten, at the White House in January, commended President Obama and Vice President Biden for their proposals to reduce gun violence and promote safety, including: Banning sales of large ammunition clips; Expanding background checks and cracking down on those who lie on background check Stopping illegal gun trafficking; Banning assault weapons; Enforcing gun laws and investing in research on stopping gun violence; and Investing in mental health services. The first solution, fortifying schools, is unlikely to be effective not simply because it is costly; a determined shooter could surveil and disarm the guards or defeat the metal detectors or other devices. Limiting media coverage might be more effective. At the moment, media coverage of these tragedies is so relentless and invasive that it effectively glorifies the shooter. If the media refused to provide such coverage, or if it were prohibited from doing so, a potential shooter might be discouraged from committing mass murder/suicide because he would realize that he will not get the postmortem fame he craves. The difficulty would be in crafting a law that accomplishes this aim while not unduly infringing on the freedom of the press. The third possibility, repealing the gun-free zone laws, shows the most promise in deterring these horrible crimes, because potential shooters would not know who else might be carrying a gun. The most common objections to allowing licensed adults to carry firearms in schools is the fear that unless such a person is as highly trained as a policeman, he is likely to shoot indiscriminately at the shooter or over childrens heads, and cause even more terror than the original shooter has provoked. Body Paragraph 3: This objection shows both a lack of an ability to prioritize and a lack of understanding of how widespread responsible gun ownership is in the United States. While state laws differ about what constitutes adequate training, the vast majority of those who are licensed to carry do so responsibly. In considering the possibility of allowing concealed carry on our law school campus, one of my colleagues stated that she would never trust her safety to Professor X, an older professor widely known for his staunch support of the Second Amendment and other conservative causes. But if (God forbid) a disgruntled former law student entered the faculty suite hoping to shoot as many faculty members as possible, I would much rather trust to the ability of Professor X (or any other professor or student or even my own skill) to shoot him and not me than on my ability to run, hide in my locked office, or try to tackle the shooter. ost mass shooters are young men or occasionally womenusually teenswho are emotionally unstable and want to exact revenge on society for some harm that they have suffered commit suicide in a blaze of gunfire, and get national media attention for their last act. Their desire to commit suicide indicates that though such shooters may be deranged, they are cognizant of the likely consequences of their acts and are acting accordingly by choosing suicide. Three possible ways of doing this are to: fortify schools with Armed guards and metal detectors as in airports, limit media coverage of mass shootings so that potential shooters recognize that they wont become famous postmortem, or eliminate the gun-free zones and allow licensed parents, teachers, administrators, and adult students to carry their guns into school. Body Paragraph 4: Senetence 1: The first solution, fortifying schools, is unlikely to be effective not simply because it is costly a determined shooter could surveil and disarm the guards or defeat the metal detectors or other devices. Limiting media coverage might be more effective. At the moment, media coverage of these tragedies is so relentless and invasive that it effectively glorifies the shooter. If the media refused to provide such coverage, or if it were prohibited from doing so, a potential shooter might be discouraged from committing mass murder/suicide because he would realize that he will not get the post mortem fame he craves. The difficulty would be in crafting a law that accomplishes this aim while not unduly infringing on the freedom of the press. The third possibility, repealing the gun-free zone laws, shows the most promise in deterring these horrible crimes, because potential shooters would not know who else might be carrying a gun. Conclusion: It cannot be overemphasized that concealed carry has reduced violent crime every time it has been passed and is therefore most likely to reduce the incidence of mass shootings in schools. This could help save Students and teachers lives. Source Citation  (MLA 8th Edition) Nedzel, Nadia E. Concealed carry: the only way to discourage mass school shootings.

DSL Technology :: Technology Computers Internet Essays

DSL Technology Introduction The accelerated growth of content rich applications and online gaming, which demand high bandwidth, has changed the nature of information networks. High-speed communication is now an ordinary requirement throughout business, government, academic, and home office environments. Internet access, telecommuting, and remote LAN access are three of the clearly defined services that network access providers are offering now. These rapidly growing applications are placing a new level of demand on the telephone infrastructure. In particular, the local loop portion of the network (i.e., the local connection from the subscriber to the local central office) has become a challenge for telephone companies. Historically, this local loop facility has been provisioned with copper cabling which cannot easily support high bandwidth transmission. This environment is now being stressed by the demand for increasingly higher bandwidth capacities. Although this infrastructure could be replaced b y a massive rollout of fiber technologies, the cost to do so would be insupportable in today's business models and, more importantly, the time to accomplish such a transition is unacceptable because the market demand exists today! Telephone companies are already faced with growing competition and unprecedented customer demands A new category of companies, Internet Service Providers (ISPs), has emerged in this market as providers of data services. Traditionally ISPs have used the telephone company infrastructure. However, thanks to deregulation, they now have direct access to the physical cable plant. ISPs will be formidable competitors in this quest for the customers. Network service providers around the world fill this moment with great potential for remarkable success. A new technology called high-speed Digital Subscriber Line (xDSL) has emerged onto this scene. xDSL, which encompasses several different technologies, essentially allows the extension of megabit bandwidth capacities from the service provider central office to the customer premises on a customer by customer basis over the existing copper cabling, without the need for massive infrastructure replacement and at very reasonable costs. These new xDSL solutions satisfy the business need to provision the network in a fast, cost effective manner, while preserving the infrastructure and allowing a planned migration into newer technologies. xDSL has the ability to meet the customer demand for high bandwidth right now, at costs that make sense. xDSL is a group of emerging Digital Subscriber Line (DSL) modem technologies for supporting high-rate traffic transmission over POTS lines. X stands for asymmetric in ADSL, rate adaptive in RADSL, high-speed in HDSL, and very high speed in VDSL.

The major companies include American, Delta, and United Continental (bts.gov). There are air operations of express delivery companies such as FedEx and UPS. This industry is highly concentrated with the 10 largest companies accounting for more than 75 percent of industry revenue (bts.gov). The global airline industry generates about $500 billion annually (tbs.gov). The major international companies include Air China, Deutsche Lufthansa, Air France-KLM, Japan Airlines, and British Airways (bts.gov). Discussion Questions 1. Discuss the trends in the U.S. airline industry and how these trends might impact a company’s strategy. Trends in this industry are numerous. This discussion will include the price of jet fuel, on-time performance, security, and cheaper substitutes. Oil price volatility is the leading player in airline strategy (jetblue.com). Fuel is probably the most significant element in an airline’s base cost (jetblue.com). The new fuel price average for the year 2012 is around 129.7 dollars per barrel (jetblue.com). The impact of this year’s fuel bill for the global airline industry is upwards of 32 billion dollars (jetblue.com). The causes for delays and cancellations of flights are reported monthly to The Bureau of transportation Statistics (bts.gov). On time performance has many factors; a few of these factors are air carrier delays, late arriving aircrafts, security delays, extreme weather, and equipment (bts.gov). Air carrier delays are within the airline’s control. This area includes maintenance/crew problems, aircraft cleaning, baggage loading, fueling, and such (bts.gov). A late arriving previous flight†¦ Read Full Essay View as multi-pages

Mother Tongue Language And Mathematics Essay

In what ways does your mother tongue language and mathematics resemble and differ from each other? Mathematics and language both act as a source of communication, thus both mathematics and language play an important role in life. According to the dictionary, language is defined as a â€Å"communication of thoughts and feelings through a system of arbitrary signals, such as voice sounds, gestures, or written symbols.† In comparison, the dictionary defines mathematics as a â€Å"the study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols.† Both language and mathematics use symbols, thus both concept are seen as a form of communication. The symbols represent values, which can be understood by the human mind. Language is defined as a code, and both the mother tongue and mathematics are made up of unique symbols that are consistent in their rules in order to be understood properly. Mathematics is a very complex, straightforward concept that has fixed meanings. If x = y = z, then x = y, x = z and y = z. This is a universal phenomenon accepted world wide. Mathematics has been used in the study of science. An example would be the physician Albert Einstein and the discovery of his equation e = mc2. Mathematics is composed of a combination of factors, which can be simplified and broken down. Factorisation of equations is an example. However, if an equation can be factored, then there is only possibility in which it can be broken down. Each equations has its universal values that cannot be altered. Even though mathematics exemplifies logic, it is not as simple to understand. In order to understand the concept of mathematics, a person has to learn a language first. Whether the language is English, French, Spanish or German does not matter. Mathematics is a fundamental base of our daily life and society, but it is not as essential as the communication between humans through the usage of language. Language is a much simpler concept than mathematics. Language does not have a fixed meaning or value, whereas this is the case in mathematics. 5 + 3 = 8. This is always true, it cannot be denied due to the mathematical code and its rule. In language this is not the case. Statements can be understood of accepted differently according to the individual. For example, Anna says to Tom, â€Å"I really like you.† This has no fixed meaning, because according to what tone this statement is said, it can either be true or false. Anna could emphasise through language that she in reality does like Tom. On the other hand, she has the ability to state it as a sarcastic phrase. This would mean, that in reality she doe not like Tom. Language also plays an important role in culture. Through language, the origin of individuals can be assumed. If somebody is mainly speaking German, then one can assume that the person is German. Even within the German language, different dialects are spoken. This makes language less specific than mathematics. There is the â€Å"Hoch-Deutsch† spoken in Germany, the Austrian German spoken in Austria and finally the Swiss German heard in Switzerland. Language is expressed in different forms, either written by the usage of symbols, orally through the usage of sounds and finally through the form of body language. Again, language illustrates a less specific concept than mathematics. All three forms can express certain values and one statement, such as â€Å"I like you† can be expressed in all three different forms. Even though both mathematics and language have codes, these can be misunderstood. In mathematics your result is an error, while in language misunderstandings can result in several problematic situations. The fundamental difference between mathematics and language is that one is universal in its concept, while the other is altered around the globe. Mathematics is universal, it has the same code throughout the world where 2 + 2 = 4 in every country. Language however, can be altered. If a Chinese speaks in Chinese to a Portuguese, it is unlikely that they will understand it each other. In conclusion, mathematics and language share both common concepts but also differ from each other. They are both essential for life, while language is the base to understand mathematics. The concept of mathematics has always been relevant in nature, such as 360à ¯Ã‚ ¿Ã‚ ½ circles. Language is the invention of the human race in order to establish and maintain the communication between each other.
