Forced Busing does NOT Work :: essays papers
Forced Busing does NOT Work There are many reasons why forced busing is not an adequate way to solve the segregation problem caused in the early twentieth century. For example, many minorities are against forced busing. In Milwaukee, sixty six percent of the urban population is against forced busing (Williams and Borsuk, 1999). This is very surprising considering that minorities are the very people that forced busing is aimed at helping. Why would minorities despise a program designed to benefit them? Busing minorities to primarily white schools is basically telling minorities that they canââ¬â¢t be educated adequately without sitting next to white people (Kreyche, 1992). This is extremely degrading for minorities. Professor Kevin Brown who has completed many studies concerning forced busing concludes that the initial reason behind forced busing was fewer resources in black schools. Brown states that the current reason for forced busing is the absence of white students in black schools. Forcing students of different ethnic backgrounds to sit next to each other is by no means integration (Coeyman, 1998). This practice is actually creating a hot zone for racism. Studies have shown that elementary school children seem to be unaffected by race. However, once these children become middle and high school students, society seems to come down on them and the students align themselves along racial boundaries (Amor, 1995) . Mandated busing gives the impression that whites are superior and blacks are inferior because the government tells them that blacks needs whites to receive an education. This argument comes to a head when the students sit next to each other in a high school class. The recent studies conducted by the American Psychological Association are not the first to focus the factors that influence how people learn. The vast majority of the studies show that the main factors influencing learning are biological factors and family conditions. Researchers have concluded that students are born with different learning capacities, which are reinforced by the way their families feel about education. Students who come from families with one parent or a family with a parent or sibling involved with crime tend to learn at a slower pace than do children who come from families with two parents. Minority students come from ââ¬Å"broken homesâ⬠more often than do white students. Hence, the conditions within the school may not be the reason for lower test scores among minorities.

External Communication Audit Essay
Social media applications are being used every day by people all over the world. These applications such as Facebook and LinkedIn are even used by employers to generate potential personnel. These two sites both provide businesses with information they need to better their impression of the applicant. As kids in college look for jobs some donââ¬â¢t understand that what you post can hurt you in an interview process. ââ¬Å"56 percent of employers said that they were likely to check out the social media presence of potential employeesâ⬠(Protalinski). This statistic shows that it really does hurt you if you have inappropriate pictures on your social media sites. Overview: Facebook ââ¬â Social media has been around for a long time and in 2004 the world was introduced to Facebook. It was created by Mark Zuckerburg along with the help of a few of his college friends who also attended Harvard. At first it was only available to Harvard students and moved to a few other college campuses. This was not just a website for people to meet and communicate over the internet; it was also a chance to get a closer look at businesses. In 2007, there were more than 100,000 business pages allowing companies to attract potential customers and tell them about themselves. Facebook took off and in 2011 over 350 million users accessed Facebook through their mobile phones. LinkedIn ââ¬â LinkedIn was founded in December 2002 by Reid Hoffman and launched in May 2003. LinkedIn is considered a business-oriented social media service that allows you to add business connections to your contacts, find potential jobs, search companies, and even add a resume. This type of socia l media is benefited by not having the ability to add inappropriate photos to hurt your chances in an interview. Having a more resume format allows potential employers to view your past work, applied skills, and education. Project Goal: Facebook ââ¬â When you apply for a job most companies now-a-days will do aà background check on you before giving you the job. This means they can look at your Facebook page at any moment. Whether thatââ¬â¢s because you have embarrassing photos or if you have posted comments that the company views negatively. Many people lose their jobs over a Facebook issue; Caitlin Davis was the youngest NFL cheerleader for the New England Patriots and in 2008 after a picture of her was posted to Facebook she was fired just six days later. The photo was of a guy passed out after a Halloween party and Caitlin was holding a marker, acting like she was drawing on him. This is just one example of how Facebook can be damaging to your career. It also is not just about pictures Facebook allows you to post comments and those too can be more damaging than any photo. Once you post a comment it is out on the internet anyone can see it and must of the time people are insensitive to others and can be very cruel on Facebook. I have read numerous fights between people where they are being completely rude and crude to other peopleââ¬â¢s feelings. Facebook give its users the ability to like bands, companies, and social figures. Going through interview employers can look at these likes, which means if you have liked any inappropriate figures they can be viewed. An example would be an underage student liking the pages or alcohol companies or illegal drugs can hurt them in an interview. LinkedIn ââ¬â LinkedIn gives people the ability to set up a professional social media site that helps them create a professional network. Creating and establishing a successful network can help immensely in finding a job. Through the LinkedIn profile you can connect with other professionals and it will show them your interest. Having applied skills in certain fields will give you an advantage when employers are looking over applicant. LinkedIn allows your connections to endorse these skills, which means they have been proven of those skills. Many employers look at references of an applicant and LinkedIn allows connections to post a reference statement, this eases this process. Only being able to upload one main profile picture reduces the risk of having any inappropriate pictures. Conclusion ââ¬â The better social media site for a business setting is LinkedIn. With a resume formatted profile it allows potential employers to better understand their applicant or even search for employees. More recruitersà look at LinkedIn to hire people than any other social media site. A point that we want to emphasize is that people, especially college kids need to clean up and watch what they post on Facebook. Employers will view your profile content whether you let them or not. LinkedIn is more popular in the business world and students should start to build this profile and network as they prepare to graduate. References Bersin, J. (2012, May 21).

Colonialization And Religion Of Barbados - 1198 Words
Colonialization and Religion of Barbados In spite of being in the Atlantic Ocean, Barbados is known as one of the top tourist destinations in the Caribbean. Now a sovereign island country, it is an independent state and Commonwealth realm. Barbados still retains the Queen of England as its head of state, as it was once an English then later a British colony. Barbados had quickly grown to be the third major English Settlement in the Americas due to prime eastern location. It was the only island that did not change hands during the colonial period. The culture of Barbados was shaped by the syncretization of colonialism and imperialism by use of religion and cultural resistance. Pre-colonization, Barbados was a small island inhabited by Amerindian, American Indians, with settlement dates from the fourth and seventh centuries AD. Though there is some evidence to suggest that the island was settled in the second millennium BC, it is formally documented as first settled by a group kn own as the Saladoid-Barrancoid, from the mainland of South America. In the year 800, a second wave of migrants came to the island that the Spanish referred to as Arawaks. The last group to come to Barbados in the mid-13th century, called Caribs by the Spaniards, was more politically organized and came to rule over the others. The Spanish found a use for Barbados as a supplier of Indian slaves for their mines in Espanola (Schomburgk 254).

Essay about Night By Elie Wiesel DOK Questions - 1285 Words
Night By Elie Wiesel Taylor Brennan October 2014 Period 6 Senior English Ms. Scimone/Hagis Chapter 1 DOK Questions: 1. Identify one character trait of Elies father. Elies father doesnt display his feelings, and he is rather distant from his family. 2. Organise the events from 1941-1944. 1941: Elie meets Moishe the Beatle when he is 13. 1942: All foreign Jews were expelled from Sighet, including Elies friend, Moishe. 1943: Daily bombings of Germany and Stalingrad occurred. 1944: German Army vehicles come into Sighet. Rules and regulations for all Jews came into effect. 3. Cite evidence to prove how the Germans manipulated the Jews. They acted politely to the women in their homes to gainâ⬠¦show more contentâ⬠¦The novel also mentions the stench of burning flesh on page 28. 3. Compare and contrast the behaviour of the Germans towards the Jews in chapter 1 and then in chapter 2. In chapter 1, the Germans were kind and polite to the Jews in order to gain their trust. For example, the Germans treated the women with respect and bought them chocolates. In chapter 2, this behaviour changed dramatically. For example, the German officers beat the Jews and had them cramped into cattlecars until they reached their destination, which was Auschwitz. This treatment is also a form of irony for the Jewish people, as they did not expect this behaviour from the polite German officers they had come to know in chapter 1. 4. Analyse how the Jews turned against each other in the cattlecars and throughout the novel. In chapter 2, the reader can infer that the Jews turn against one another. For example, When Mrs. Schà ¤chter was yelling about the fire, the Jews attempted to calm down/soothe her. As time passed, her screams excelled and were causing the passengers to become upset and anxious. They then started to beat Mrs. Schà ¤chter to silence her. The reader can also infer that this behaviour continues throughout the novel because nobody can trust anyone and the Jews had to fend for themselves in these harsh concentration camps.

The Importance of Physical Activity Essay - 1229 Words
Physical Activity is undeniably good for everyone, not only does it keep you fit and healthy but when started at a young age, it can set up good habits for life. Sometimes however, people do not take care of their physical wellbeing, resulting in obesity and other eating disorders which can be detrimental to their health. Obesity is the condition of being seriously overweight. It is now considered a global health epidemic by the World Health Organization (2000) (McDevitt Ormrod, 2010). Physical activity is important to children in the middle childhood age group because a staggering amount of children have become overweight in the last few decades and teachers play a role in preventing obesity by becoming a positive role model,â⬠¦show more contentâ⬠¦It is because of this high level of cognitive function that physical activity and nutrition are extremely important (McDevitt Ormrod, 2010). They affect the childââ¬â¢s physical wellbeing in terms of energy levels, growth and the ability to concentrate (McDevitt Ormrod, 2010). As children grow they continue to need physical activity. One of the methods of exercise that is popular with children in the middle childhood age is rough and tumble play or ââ¬Ëplay fightingââ¬â¢ (McDevitt Ormrod, 2010). Unfortunately, this sort of play is often discouraged by schools because of the possibility that someone may become injured. (McDevitt Ormrod, 2010). Teachers must find the balance between protecting children from getting hurt and allowing them to run and jump to release the copious amounts of energy that they have to burn (McDevitt Ormrod, 2010). Another unfortunate hindrance to physical activity in schools is the notion that physical activity takes away from time that could be used for academic studies. This is unjustified however, because children of this age group are unable to sit and concentrate for long periods of time without being able to get up and move (McDevitt Ormrod, 2010).

Wearable Technology and Sensors
Question: Identify and describe at least three advancements, achievements or significant events that have been accomplished because of increased exposure, awareness or interventions from public health initiatives. Answer: Primary prevention and health promotion are the basic components in public health nursing, population and community. Many significant events, achievements and advancements have been accomplished in the public health care due to the interventions, awareness and increased exposure from public health initiatives (McGregor Harris, 2014). Those advancements, achievements and significant events are described below: Advancements: Three advancements are described below: Wearable technology andsensors: According to a Transparency Market Research report, the market of medical devices is growing at the rate of 16.4 percent a year. These sensors and wearable medical devices help to collect the medical data, which is the main purpose and aim in healthcare. An example of this sensor is a bandage, which can inform about the infection in the wound through changing in skin pH level (Park, 2013). An older patient can send alert to the care provider with the help of this sensor within a fraction of second. There are many wearable tech products, which utilize multiple digital health sensors. These sensors are composed of ambient sensors and other body worn sensors, which are integrated into sensor networks. A smart sensible chip is inserted in these devices. Therefore, the healthcare people get to know about medical information with these data points. The main target of the wearable technology in healthcare is to make profitable and big market by 2020. Geospatial Technology: Geospatial technology has multiple functions in healthcare. But the main aim of this technology is to make the public health better through providing information. In this technology, the data are collected, analyzed and then the result is displayed through a multilayered map. Virginias GeoHealth Innovation is a company with this technology (Patel Patel, 2016). The chart of this company was made based on social factors, youth and adult health risks, mortality rates, infant and mental health, which influence the population health. The community and professionals get information about health care after seeing this multilayered map in the International Journal of Health Geographics. This helps the medical professional to improve the health system in that area. Self-service kiosks: Self-service kiosks are certain devices which simplify the hospital registrations of the patients. Patients can do this registration without talking to anybody. These automated kiosks help the patients in registration requirements, signing paperwork, checking identification, paying co-pays etc. different tablets are there with this technology which are used for the bedside patients and outpatients (Booth, 2015). But, the people also have to keep in mind that human communication should not be eliminated completely. Achievements: Three advancements are described below: Vaccination to lower down epidemic diseases: Infectious diseases like, pertussis, diphtheria, measles, smallpox were widely spread at the emerging of the 20th century. The death rate was increasing due to its adverse effects (Mobini et al., 2013). Both the promotion and development vaccinations to lower down these diseases have resulted in dramatic fall in mortality and morbidity. Such example is eradicating small pox. Increased travel safety: The research shoes a significant fall in death rate due to travelling. Over the years , it is observed that annual death rate due to risk in motor vehicle travelling has decreased by ninety percent (Druss Dimitropoulos, 2013). Some of the interventions with enforced and developed regulations are booster seats, child safety, pedestrians, young drivers, alcohol-impaired drivers, safety belts etc. Safe work atmosphere: According to National Institute for Occupational Safety and Health and National Traumatic Occupational Fatalities, the death rate of the people due to work issues has fallen down from 28% to 48% decrease (Tompkins Smith, 2013). This is a good indication for the workaholic people to do their job safely. Significant events: Three significant vents are described below: Healthy People 2020: TheUnited States Department of Health and Human Services has set a program named Healthy People, whose main goals are disease prevention and heath promotion. This program was first established in 1979. The first issue described a report whose aim was to lower down the controllable health risks for ten year plan (Srinivasan et al., 2014). In its nutrition sector, reports about diet with less red meat, poultry and fish, more complex carbohydrates, sugar and salt, cholesterol, less saturated fat, were recommended. This Healthy People issues were revised with updated goals. Those issues are Healthy People 2020, Healthy People 2010, and Healthy People 2000. The main aim of the Healthy people 2020 for immunization of the infectious diseases is rooted in community and clinical services and activities for the treatment and prevention of infectious diseases. The new goals of Healthy People 2020 will emphasize on technical advancements and ensuring that nongovernmental organizations, local pub lic health departments and states should become strong partners. This attempt will be made in the nation to control the spared of the infectious diseases. The aim of 2020 reflects a more mobile society and the diseases will not stop at geopolitical borders. Awareness of disease and completing treatment and prevention courses remain essential components for reducing infectious disease transmission. Remote monitoring tools According to Market and Research report, 2.8 million people are taking advantage of home monitoring system by the end of 2012. Unnecessary visits to the doctor and cost are reduced due to this home monitoring system. Cardiac cast is such a system, which is associated with pacemaker. It transmits the data from patients body to the remote centre (McGregor Harris, 2014). The patients will be informed immediately if any wrong thing happens. The family members of the patient can monitor through this system. This system is very important for chronic and serious illness patients. The research studies have showed that these, monitoring tools have lowered down the readmission rate of the heart patients. Affordable Care Act: Finally, Affordable Care Act (ACA) was introduced into the law after yearlong, intense debate. This act addresses a series of comprehensive health insurance reforms including medical coverage for adults under 26 years old, free preventive care, creation of health insurance market places etc (Druss Dimitropoulos, 2013). It helps the older people to get medical coverage in very low cost. The ACA was introduced to increase the affordability and quality of the health insurances and to lower down the uninsured rate. This is achieved by reducing healthcare costs for government and individuals and by expanding private and public insurance coverage. The introduced mechanisms are insurance exchanges, subsidies, mandates etc. According to the law, the insurance companies will offer the same rates regardless of sex and pre-existing conditions. It will also cover all applicants within new minimum standards. In the conclusion, it is stated that there are many achievements, advancements in primary health care practice over the years. Still, there are many cases, where these advancements failed. Due to these advancements, the systems are becoming automated. It leads to unemployment. The researchers are focusing on these advanced systems to get the best result out of this. References: Booth, R. G. (2015).

Maintaining Marine Reef Aquarium Essays - Fishkeeping, Anthrozoology
Maintaining Marine Reef Aquarium Important Aspects in Maintaining a Marine Reef Aquarium There is something fascinating and relaxing in having an aquarium in a home. Like a fireplaces warm glow and bright colors, the colors that are emitted from an aquarium can be just as warm and even more colorful. From the slow and graceful movement of the fish to the frantic feeding frenzy, an aquarium is different each time it is viewed. Although a freshwater tank can be full or color, it does not come close to the fiery colors that are present in a marine aquarium. Unfortunately, all the color and life that a marine aquarium holds is much more fragile and not as easy to keep as a freshwater tank. Therefore, the marine aquarium requires a plethora of devices working together and at optimum levels to maintain a successful tank. Items like protein skimmers, ultraviolet filters, sump filters, reverse osmosis units, and even wave-makers are just a few of the devices that are required to properly maintain a marine aquarium. With the exception to a properly constructed tank, nothing is as important to the marine aquarium as the water within the tank and the lighting given its inhabitants. Since water is the medium that the aquarium inhabitants must live in, it is the most vital component in any tank. The quality of the water used will directly effect how successful the aquarium is. The chemical balance of the water must be watched closely. If the salt content varies too much, or harmful chemicals build up, the water will kill the inhabitants of the tank. Since fresh pure sea water is not readily accessible, the easiest water source for the majority of hobbyists is the faucet. However, the tap water that comes from the local water treatment plants may be safe for human consumption but is most likely toxic to marine life. Water treatment plants remove most of the harmful chemicals, but the water delivered is anything but pure. Often this tap water contains high levels of phosphates and nitrates that can be harmful to aquarium inhabitants. Also, copper may leach from pipes, and it is deadly to marine invertebrates (Goldstein 8). This leaves very few options for water to the hobbyist. One of the last, and probably the best option for obtaining a pure water source is by using reverse osmosis water. Reverse osmosis is a process of filtering out pollutants from water to create a purer form. Mr. Dakin who has written several books on maintaining a reef aquarium describes osmosis in his book as a natural process by which selective molecules in an aqueous solution can be pass through a semi-permeable membrane, while the movement of other molecules due to size, shape or other reasons is restricted (20). Once water has been allowed to flow through this membrane, purer water can be collected from the output of the filter. Once enough of this water is collected, the hobbyist can fill the aquarium and begin to plan on his or her next step, the salt content. Although ocean water tastes like water with table salt (sodium chloride) dissolved in it, it is a lot more complex than that (Friese 33). Pure sea water contains a vast amount of dissolved chemicals. It contains everything from sodium chloride to trace amounts of silver and gold. Although the inhabitants of a marine reef aquarium are not going to be effected if the water does not contain gold, they will not live long if all that is added is table salt (Friese 33). Marine salt mixes contain a similar collection of elements that are found in natural seawater. There are many different brands of aquarium salt available to the hobbyist, and each one has its own following of people that will swear by its use. Any brand available will work since it is very unlikely the inhabitants will be able to tell the difference. However, what is more important than the brand of sea salt is the amount that is added to the water. Water in the open ocean contains around 34 parts of dissolved inorganic materials for every 1000 parts of water (Friese 34). This is where the marine reef inhabitants live and thrive. For
