The Long Walk Home Essay Example For Students

The Long Walk Home Essay African Americans fought for their rights for a long time. Since the 16th century, African Americans have been fighting for their freedom and equality. They have been treated as slaves and discriminated by the white people. Their situation got better as time went by, but until the 19th century they were still treated differently. The Montgomery Bus Boycott occurred during the 1950s, which marks the beginning of the Civil Rights Movement by the African American community. In the movie The Long Walk Home, it shows us the challenges and sacrifices faced by the African American community to end the very hard life they have been experiencing for a long period of time in America. In the 1950s, the Montgomery Bus Boycott happened. During that time segregation was happening in some places like Montgomery, Alabama. There was a bus segregation which means white people sit on the front seats and black people sit at the back seats. After the incident that happened with Rosa parks, a black woman who refused to give her seat to a white man was arrested by the police.

This movement for equality required a huge sacrifices and obstacles endured by the African American community. Many African Americans didn’t own a car, so they walked to work and home everyday in support of the Boycott. In the movie, we see that Odessa walked miles to work and home. African American women were treated harshly by white men. In the movie, there’s a scene when Odessa is discriminated by a police officer at the park. Another scene is when Odessa’s daughter and son was threatened and hurt by three white men. This shows us how harshly black people were treated because of the movement they were doing to gain equality. During this challenging events African American community unitedly stand to sought victory. During this time when African American were fighting for their equal rights, the church was their source of hope. The church was a place where they did not fear the society they were living in. In the last scene in the movie, we see how united they were, it was the moment when black people were screamed at and told to surrender. This was a memorable moment because they didn’t fight back instead they sing which they proved that violence won’t solve the issue. African Americans proved that their unity was important to their long sought victory. Despite the struggles faced by the African Americans Miriam Thompson, a white woman, supported the bus boycott. At first she didn’t want to be involved with it, but as time went by and she realized how racist the people around her she decided to do what’s right. She drove Odessa, her maid, to work and later on she began helping the other black people by doing a carpool. Miriam Thompson sacrificed a lot for what she think is right. She sacrificed her relationship with her husband and her surrounding community. Because of what she did it shows us the equality that will happen in the future. The African American community gave their full effort and sacrifice a lot for their equality. They endured all the obstacles and faced it bravely to gain freedom and acceptance. This movie changed the public views on them, they proved to the people of that time, that they’re part of America and people like them deserve acceptance and equality.

Coca (Cocaine) History, Domestication, and Use

Coca (Cocaine) History, Domestication, and Use Coca, the source of natural cocaine, is one of a handful of shrubs in the Erythroxylum family of plants. Erythroxylum includes over 100 different species of trees, shrubs and sub-shrubs native to South America and elsewhere. Two of the South American species, E. coca and E. novogranatense, have potent alkaloids occurring in their leaves, and those leaves have been used for their medicinal and hallucinogenic properties for thousands of years. E. coca originates from the montaà ±a zone of the eastern Andes, between 500 and 2,000 meters (1,640-6,500 feet)  above sea level. The earliest archaeological evidence of coca use is in coastal Ecuador, ca 5,000 years ago. E. novagranatense is known as Colombian coca and it is more able to adapt to different climates and elevations; it first up in northern Peru beginning about 4,000 years ago. Coca Use The ancient method of Andean cocaine use involves folding coca leaves into a quid and placing it between the teeth and the inside of the cheek. An alkaline substance, such as powdered wood ash or baked and powdered seashells is then transferred into the quid using a silver awl or pointed tube of limestone. This method of consumption was first described to Europeans by the Italian explorer Amerigo Vespucci, who met coca users when he visited the coast of northeastern Brazil, in AD 1499. Archaeological evidence shows the procedure is much older than that. Coca use was part of ancient Andean daily life, an important symbol of cultural identity in ceremonies, and used medicinally as well. Chewing coca is said to be good for relief of fatigue and hunger, beneficial for gastrointestinal illnesses, and said to ease the pain of dental caries, arthritis, headaches, sores, fractures, nosebleed, asthma, and impotence. Chewing coca leaves also is believed to ease the effects of living in high altitudes.   Chewing more than 20-60 grams (.7-2 ounces) of coca leaves results in a cocaine dose of 200-300 milligrams, equivalent to one line of powdered cocaine. Coca Domestication History The earliest evidence of coca use discovered to date comes from a handful of preceramic sites in the Nancho Valley. Coca leaves have been direct-dated by AMS to 7920 and 7950 cal BP. Artifacts associated with coca processing were also found in contexts dated as early as 9000-8300 cal BP. What is the AMS dating method?What does cal BP mean? Evidence for coca use has also been from in caves in the Ayacucho valley of Peru, within levels dated between 5250-2800 cal BC. Evidence for coca use has been identified from most cultures in South America, including Nazca, Moche, Tiwanaku, Chiribaya and Inca cultures. According to ethnohistoric records, horticulture and use of coca became a state monopoly in the Inca empire about AD 1430. The Inca elites restricted use to the nobility beginning in the 1200s, but coca continued to widen in use until all but lowest classes had access at the time of the Spanish conquest. Archaeological Evidence of Coca Use Nanchoc valley sites (Peru), 8000-7800 cal BPAyacucho valley caves (Peru), 5250-2800 cal BCValdivia culture (3000 BC) of coastal Ecuador (may represent long-distance trade or domestication)Peruvian coast (2500-1800 BC)Nazca figurines (300 BC-AD 300)Moche (AD 100-800) pots illustrate a bulging cheek, and coca leaves in gourds have been recovered from Moche tombsTiwanaku by AD 400Arica, Chile by AD 400The Cabuza culture (ca AD 550) mummies buried with coca quids in their mouths In addition to the presence of coca quids and kits, and the artistic depictions of coca use, archaeologists have used the presence of excessive alkali deposits on human teeth and alveolar abscesses as evidence. However, it isnt clear whether abscesses are caused by coca use, or treated by coca use, and results have been ambiguous about using excessive calculus on teeth. Beginning in the 1990s, gas chromatography was used to identify cocaine use in mummified human remains, particularly the Chirabaya culture, recovered from the Atacama Desert of Peru. The identification of BZE, a metabolic product of coca (benzoylecgonine), in hair shafts, is considered ample evidence of coca use, even for modern-day users.

Delay Retirement as Housing, Stock Swoon Essay Example | Topics and Well Written Essays - 500 words

Delay Retirement as Housing, Stock Swoon - Essay Example The housing bubble of 2008 caused many Americans to lose thousands of dollars in equity value. The housing market used to be so good that many Americans bought a second property for investment purposes. Those people that choose the route of investing in the house market for profits have taken a huge hit since the majority of properties in the United States have lost a lot of value. According to the article the housing market in the U.S lost over 10% in value in 2008. Along with a depleting housing market retirees have also seen their other investment instruments go down in value in a significant manner. One of the financial retirement instruments that people invest on the most is 401k plans. These plans often invest a lot of money in the stock market. The value of stocks or equity went down approximately 15.5% in 2008. The loss of value hurt the potential retirees the most because older people do not have the leisure of time like young people do. A young person can wait until the market picks up once again. Retirees depend on that equity money to help pay for their living expenses. The combined effect of the devaluation in the stock market and the depreciation of homes has force many senior citizens to continue working instead of retiring early. As of 2008 approximately 78 million baby boomers reached the age of 60. Many of these individual planned on retiring early, but a lot of them have found it extremely hard to make a commitment to retireme nt due to the fact that the value of their retirement savings has gone down. The senior citizens that are supposed to retire are holding on to jobs that younger people need. This has created market inefficiency in the labor markets. There are so many jobs to go around in the United States. The current situation is unfair to both young people and older people.

How the present day data centers are turning to virtual data centers Research Paper

How the present day data centers are turning to virtual data centers - Research Paper Example The Hyper-V process allows the virtual machine user to craft and manager one’s virtual machines process by implementing the popular virtual technology. Hyper V operates effectively in the Windows Server 2012 setup. Hyper-V allows the virtual machines user to run several operating systems together, starting and ending at the same time on a solo physical computer. The process includes implementing the different operating systems on a separate virtual machine. Consequently, memory usage can be increased more effectively and more efficiently. Virtual machines use lesser memory compared to physical machines, saving cost by increasing the virtual machines’ restarting functions. Hyper V administration implements strict security measures by implementing a local administrator’s setup (http://technet.microsoft.com). In addition, Harley Stagner (2009) insists that Microsoft’s Virtual Server 2005 Release 2, Hyper-V is a bare metal server virtualization product. The op erating system does not sit between the hardware and the hypervisor (the code implements the server virtualization process). The hypervisor (Hyper-V) is generates processing on Windows Server 2008. The Windows server is the parent partition, respectfully a privileged guest virtual machine. Virtual machines have gained popularity in the computer environment. To join the bandwagon, Microsoft offers Hyper –V program. The program works in Windows Server 2008 R2 and Windows Server 20008 infrastructure environment. Hyper-V enhances software infrastructure and management tools needed to craft and administer the virtual server system. Hyper-V contains dynamic memory. The virtual environment augments and improves the use of the physical machine environment (http://technet.microsoft.com). How the move to virtualization affects our data networks today. Singh Amit theorized the move to virtualization enhances data network processing today (http://www.kernelthread.com). First, virtual mac hines can combine the data processing of many less maximized servers to a lesser number of machines, including only one server consolidating machine. Consequently, the users can reduce avoidable costs. Second, virtual machines increase the effectiveness and efficiency of legacy processes. Virtual machines help in the individuals’ or companies’ strive to achieve goals and plans. The same processes may not work on newly installed hardware or newly bought operating systems. Likewise, the use of the newly installed hardware or newly bought operating systems will not maximize server use, unlike the virtual machines (http://www.kernelthread.com). Further, virtual machines offer enhanced security that includes isolated sandboxes to access and process trust-lacking programs or websites (http://www.kernelthread.com). One can implement address obfuscation to implement on the fly environments that are downloaded from the internet sites, increasing the danger of accessing trust-la cking websites. Such websites may steal information from the downloading computer and wreak havoc on the computers’ processing time and processing output quality. Virtual machines popularity is based on the concept of creating secured computing environments (http://www.kernelthread.com). Furthermore, virtual machines offer hardware illusions and configure the users’ hardware, which is absent (http://www.kerne

The benefits associated with exercising Essay Example for Free

The benefits associated with exercising Essay 1. Exercising lowers your risk for disease There’s no question losing weight is good for your health, and kicking your fitness up a notch has even greater benefits. Regular exercise has been shown to boost mood and banish anxiety, and lower your risk for stroke, Type 2 diabetes and certain types of cancer. It can also help you fall asleep quicker, and into a deeper sleep (just don’t exercise too close to bedtime). All great reasons to get your body moving on a daily basis! * It burns off blood sugar Recent Czech research showed that three months’ strength training improved insulin sensitivity in men with insulin resistance. A British study confirmed that exercise was linked to reduced metabolic syndrome—and that people who were unfit to start with benefited even more from the physical activity than those who were reasonably fit when they started. * It controls weight Exercise burns calories so you lose, or at least don’t gain, weight. A recent study showed that among people whose BMI averaged 41 (that’s morbidly obese) those who lost just 7 percent of their body weight through regular exercise regained healthy blood pressure and triglyceride levels, and the inflammation in their arteries dropped by between a quarter and a third, even though their BMI still averaged 38 (still too high). Numerous studies have confirmed that you don’t need to be skinny to be physically fit. * It cuts total cholesterol The major and most important effect of exercise is to raise levels of â€Å"good† cholesterol, thus reducing total cholesterol levels. An international review of multiple studies revealed that adding exercise to a weight-loss diet not only raised the good cholesterol but also increased the benefits of the weight-loss program and reduced triglycerides and blood pressure. * It reduces your heart rate Every 60 seconds, the average couch potato’s heart beats 70 to 75 times. An active person’s heart, on the other hand, is so strong that it can pump the same amount of blood in only 50 beats. That’s 36,000 fewer beats every day and 13 million fewer by the end of just one year. Exercise strengthens your heart and saves it having to work at a higher rate all the time. * It breaks bad habits In a study of 280 women, U.S. researchers found that those who gave up smoking were twice as likely to stay smoke-free—and gained half as much weight—as those who gave up without exercising. * It lifts stress and sadness The positive effects of exercise on mood were demonstrated in a British study where sedentary adults were randomly assigned to moderate intensity aerobic exercise, stretching exercises or none at all, for 12 weeks. Those in the moderate intensity group reported reduced tension, anxiety and confusion. The others did not. Additionally, a Berlin study revealed that just 30 minutes a day of exercise can be more effective than antidepressant drugs in treating depression. Exercise stimulates the brain to produce endorphins—the body’s â€Å"feel good† hormones. It has two other advantages: it acts immediately and has few harmful or dangerous side effects. * It could save your life According to the World Health Organization, inactivity causes 2 million deaths worldwide annually and is a major factor in breast and colon cancer, diabetes and heart disease. The World Hear Federation believes that inactivity is as bad for you as smoking a pack of cigarettes a day. 2. Be a good role model Child obesity is becoming a serious problem. Approximately 26 percent of Canadian kids aged 2-17 are overweight or obese. Even scarier, stats show that for the first time ever, today’s children will have a shorter life expectancy than their parents. With school gym programs being reduced and  screen time on the rise, we need to be our kids’ fitness role models. Encourage fitness by taking family walks after dinner, or trying out the Family Circus class. 3. Exercise boosts energy Winded by grocery shopping or household chores? Regular physical activity can improve your muscle strength and boost your endurance. Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently. And when your heart and lungs work more efficiently, you have more energy to go about your daily chores. 4. Fully enjoy the things you love The more fit you are, the easier it will be for you to take part in the activities you enjoy. Whether it’s going for a hike and experiencing the outdoors, or playing with the kids, you’ll find yourself more able to keep up, and less short of breath. 5. Ease back pain and improve your posture A daily regimen of stretches and exercise can also do wonders for your back. By strengthening your core abdominal muscles, you’ll increase your overall strength, taking the pressure away from your back and helping to alleviate any existing back pain. 6. Take some time for yourself Whether it’s an early morning jog, an afternoon cycle class or a late night walk with the dog, solo exercise gives you the opportunity to have a few moments of peace and quiet, think about future goals, and take some much-deserved â€Å"you† time. It’s also the perfect excuse to listen to your favourite soundtrack while you work out!

Comparing Crime in Beloved, Crime and Punishment, and Utopia :: comparison compare contrast essays

Crime in Beloved, Crime and Punishment, and Utopia      Ã‚  Ã‚  Ã‚  Ã‚   To begin with an omniscient and philosophical frame of reference, crime is only defined as crime by the society defining it.   When a mass of human beings coagulate to ¬ gether and form a civilized society, they are bound to make rules and laws to follow and bide by; for laws are one of the cornerstones of a civilized society.   If there were no laws, society would be uncivilized and in a chaotic state of anarchy.   These laws are decided and administered usually by elected officials who act as leaders in the society.   From the input of the citizens, they make laws to run the society by.   And when a person breaks the law, that is defined as a 'crime'.   For example, purposeful and alleged manslaughter is a crime, because it is a law to not kill others; people are not allowed to go cavorting around killing whomever they please, if they did, civilization would fall.   Laws and rules hold us to civilization.      Ã‚  Ã‚  Ã‚  Ã‚   Another way to define crime is through ethics and morals.   Each person on this Earth possesses a conscience; when we do something wrong, our conscience makes us feel guilty, although some people feel less or more guilt than others about certain acts; it varies individually.   Based on this, one can define a crime as the things that make us feel guilty, although some crimes do not make us feel guilty.   Some people do not feel any guilt when committing immoral acts; these people are deemed psychopaths or sociopaths by society. For example, most people do not feel guilty when they break the law by speeding, its just a way of life these days, but with complex ideologies (stealing, killing), we feel guilt if they are committed.   Our consciences also hold us to civilization.      Ã‚  Ã‚  Ã‚  Ã‚   In Dostoevsky's Crime and Punishment, the laws are already defined in Early Nineteenth century St. Petersburg, Russia.   Henceforth, when one breaks a law they have committed a crime and are eligible for arrest and punishment by the upholders of law in society, the police.   A particular act that is defined as criminal is that of murder. Raskolnikov knows of this very well, for he has

Ovania Case Analysis

Ovania Chemical Corporation, a producer of specialty chemicals, is taking the initiative to modernize. The modernization will include redesigning jobs performed by employees. The most critical job the company is evaluating for redesign is the position of the System Analyzer. This position is critical to operations because the system analyzer is responsible for monitoring all of the chemical components used in the production of goods. Ovania is looking to automate this position which will require system analyzers to have more technical skills. Overall, the changes the company is implementing will change the tasks, duties, and responsibilities of this position by more than 70 percent. The company anticipates that the transition to this new system will be a two year process. Ovania has already developed a committee to design the potential skill set that they feel will be needed to perform the system analyzer job and testing to evaluate that skill set was developed. Recruiting new applicants for the newly designed position was done internally and externally, with emphasis on recruiting from within the organization, as well as current system analyzers who were willing to retrain, prior to the two year implementation, for their positions. Prescreening for skills and experience were not considered as part of the application process in order to encourage a more diverse pool of applicants. Concern were raised, however, that some protected classes may find the position objectionable based on some of the requirements, such as entering treatment tanks to read gauges because the work is quite dirty. Applicants would be considered based on their performance on aptitude and ability tests. Testing would only take place for skills which the company felt it could not reasonably train an applicant for prior to the two year implementation date. The cutoff score for testing was decided upon and after testing the company has narrowed the pool of applicants to twenty, however he testing itself has been problematic for the organization, because the position is new and no validity or normative data exists to base the testing on. The key issue facing Ovania is the validity of the testing procedure for the new position. Because no prior data exists, Ovania needs to be certain that the criteria selected for testing is actually valid for the position of system analyst. How does a company such as Ovania conduct a job analysis for a position that does not exist yet? By looking at the current position requirements (duties and tasks) as well as the current job description, Ovania can develop guidelines for the new position. While this position will be different from the current job requirements, some of the areas included in the current job analysis will be valid for the new position as well. Any new skills and responsibilities the company anticipates may be required could be researched based on analysis already conducted within the industry for similar jobs. Leaving room for additional requirements and noting that the analysis methods may change as the position develops will also be key, however primary responsibilities and skill sets for applicants should be established based in research specific to the industry and based on similar positions. Did Ovania choose content-valid selection criteria? What other predictors may be useful? Selection criteria used by Ovania is content valid for this position, as it samples the knowledge and skill necessary to perform the job. Ovania may also benefit from learning about applicants previous performance in related positions and physical ability testing for this position. Given the technical nature and level of responsibility required for this position, prior job performance data will be valuable in assessing capability of the applicant. Why not hire someone fully trained now? Ovania has decided that it is willing to train any skills it deems reasonable to be acquired prior to the two year implementation date. The advantage of this approach is that the selected applicant will be trained ccording to the development of the position over that time and will be familiar with the company environment. The disadvantage is the cost of that training to Ovania should the applicant decide to leave or not work out in this position. Should the concern about women getting down into the dirty treatment tanks have been a selection issue? How might you include this factor in a selection battery? The issue of getting in the dirty treatment tanks should not be considered for just female applicants, but should be addressed with all applicants for the position as it is a required part of the position for anyone chosen for the job. This should be part of the developed job description and all applicants selected to be interviewed should be five the description for the position and emphasis made that checking the gauges in the treatment tanks is a mandatory requirement. They should have full understanding that if they are not willing to perform this part of the job they will not be considered for the position as it is necessary to the safety of the plant operations.
