Affirmative Action And Its Effects On The United States
On March 6, 1961 President John F. Kennedy issued Executive Order 10925, which included a provision that government contractors take affirmative action to ensure that applicants are employed, and employees are treated during employment, without regard to their race, creed, color, or national origin.â⬠Affirmative Action policies have always been controversial, largely because of the allegation that they cause employers to give preference in hiring to less-qualified minorities or females over more-qualified white males. Affirmative action was first created in an effort to help minorities overcome the discriminative obstacles that were present when the bill first took action in 1965. However, since that time affirmative action has evolvedâ⬠¦show more contentâ⬠¦There is a misconception that competition is bad; that self-esteem will be irrevocably damaged. If a student can experience the thrill of winning and the disappointment of losing early in life through competitive spo rts, they will be well equipped for the reality of life. Competition provides motivation to achieve a goal; to demonstrate determination, creativity, and perseverance to overcome challenges; and to understand that hard work and commitment leads to a greater chance of success. Life is full of situations where there are winners and losers: a sports game; getting a job; bidding on a contract; not getting into the desired college. However, if competition is removed, subsequently the need to work harder is removed. Affirmative action removes that competition. There are two aspects of high school that produce competitive and active workers affected by affirmative action. The first is sports. Any public school choosing to support athletic teams is required to have a minority represented by a certain percentage of a team depending on the population and demographics of the school, despite whether or not they fulfill the qualifications required by the coach or administration. For example, if the school has tryouts and there can only be a certain number of players, if everyone who makes the team fits within a certain demographic, the coach must disregard requirements and scoring and ensure that a portion of

What Chemistry Means to Me - 728 Words
What chemistry means to me and how it impacts upon my life From the foods we eat and the medicines we take to the products we regularly use, our lives are inextricably linked to chemicals and their operating principles. Chemistry is everywhere. The air we breathe, the ground we stand on, the seas we sail, and the variety of living things including our own bodies; all these are made of substances that we call chemicals. These chemicals interact with one another, and, in many cases, these interactions produce new substances through processes known as chemical reactions. Over time, in high school I have learned much about chemicals and have mastered numerous chemical reactions, giving me the ability to modify existing substances andâ⬠¦show more contentâ⬠¦Even the gas and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used every day, burning wood or other fossil fuels, chemistry is all around you each and every day.

According to Don Showalter he stated that ââ¬Å"each of these reactions between substances illustrates a concept of the way matter behaves.à ¢â¬ According to Roald Hoffmann ââ¬Å"matter is neither created nor destroyed.â⬠Research and deduce from your findings which use of metals came first- was it for weaponry or jewelry From my research that I have done there is no historical documentation, but the most likely metals are copper and gold because they are both comparatively easy to find as natural ores, and are both soft enough to use without forging equipment. Both metals were used by many ancient cultures for jewelry and decorative uses; copper was also used for simple tools. Copper is perhaps one of the most important elements for mankind, both due to its multiple uses and to its capacity to replace iron in many cases. Starting with making objects out of copper and continuing, as mankind progressed, with its use as a good electricity conductor and building material, copper was part of everyday life ever since the copper age.

Influence of Advertising free essay sample
The Influence of Advertising The Influence of advertising on our lives for both children and adults has been enormous. In todayââ¬â¢s society, it stands for communication, motivation, opportunities, information as well as art. However at the end, the purpose of all of these factor is business. Every advertisement has a clear purpose, no companies will put out an ad on tv or radio without a clear purpose because the cost for putting out an ad in todayââ¬â¢s society is immense. In todayââ¬â¢s society, beauty ads have large party of advertising, beauty ads not only have effects on the older generation, they also have effects on the young generation. For the young generations, beauty ads convey the message of the secrets or methods to stay young, and for the older generations, beauty ads convey the message of how to become and look young again. The beauty ads today are not only advertising their product but advertising the belief theyââ¬â¢re trying to sell to the people, mostly females.

For those people who are old ââ¬Å" To age is to learn the feeling of no longer growing, of struggling to do old tasks, to remember familiar actions. As curtin mentioned. However As the belief of beauty product can make people stay young, more and more older generations started to forget their ages because of their temporarily younger appearance . For those people who are young, the companies are trying to sell them the idea of the secret of retaining young. It is a false method to make the young generation to believe they can stay young forever because eventually one day they will wake up and realize all the money they spent on their beauty product was a waste, and there is nothing that can keep them young forever. The negative effect of beauty products that apply to all generations is the obsession of buying these products, and pay too much attention about their physical appearance. This negative effect will create a false sense of needs in people, when in fact they do not really need the items and the products that they are buying. and thanks to advertisements, this illusion is easily perpetrated, The products being offered through advertisements appear to be the tickets to happiness and ageless.

What to Do When a Possessive Blocks Punctuation
What to Do When a Possessive Blocks Punctuation What to Do When a Possessive Blocks Punctuation What to Do When a Possessive Blocks Punctuation By Mark Nichol When one refers to a city followed by the name of the state or a larger entity in which the city is located, the larger entity is set off from the smaller one by a pair of commas. But how do you treat such a reference when the place name is possessive? Revise the reference. A DailyWritingTips.com reader sent me this note: ââ¬Å"I came across this in this morningââ¬â¢s New York Times: ââ¬Å"In Portland, Oregonââ¬â¢s Pearl District, Dave Trausneck said he draws inspiration from the many states he has called home.â⬠I suppose there should be a comma after Oregonââ¬â¢s but it sure would look hinky. Itââ¬â¢s an awkward little phrase. What do you think? Should it be recast to read, ââ¬Å"In the Pearl District, in Portland, Oregon, Dave Trausneck said he draws inspiration from the many states he has called homeâ⬠? Oddly, as far as I know, this question is not resolved in any writing or editing handbooks, but some online commentators agree with the reader and me that a comma after Oregon would be quite hinky. But the New York Times usage, as she suggests, possesses some hinkiness of its own. I would change it with a revision similar to hers, but with a construction that reduces the comma count: ââ¬Å"In the Pearl District of Portland, Oregon, Dave Trausneck said he draws inspiration from the many states he has called home.â⬠A similar aberration appears in such sentences as ââ¬Å"The Albany, New York-based company was founded in 1999.â⬠Technically, the hyphen, to demonstrate that ââ¬Å"New York,â⬠not just York, is being attached to based as a phrasal adjective, should be an en dash, but that subtlety is lost on many readers (and writers). Regardless, itââ¬â¢s better to write around this style break: ââ¬Å"The company, based in Albany, New York, was founded in 1999.â⬠Alternatively, consider whether ââ¬Å"based inâ⬠is superfluous itââ¬â¢s relevant only if the company is headquartered in Albany, New York, but has other locations and delete the phrase if appropriate: ââ¬Å"The Albany, New York, company was founded in 1999.â⬠Then thereââ¬â¢s the intrusive insertion of a parenthesis between the possessive form of a name and the noun it refers to, as in ââ¬Å"The law went into effect when Russiaââ¬â¢s (then the Soviet Union) road use was not as heavy because fewer citizens owned vehicles.â⬠Should ââ¬Å"Soviet Unionâ⬠also be possessive? No, because itââ¬â¢s a parenthetical insertion of the different name of the country during the period being referred to. But revise the syntax to avoid the possessive form altogether: ââ¬Å"The law went into effect when road use in Russia (then the Soviet Union) was not as heavy because fewer citizens owned vehicles.â⬠Want to improve your English in five minutes a day?

The French Revolution Essay Example | Topics and Well Written Essays - 500 words
The French Revolution - Essay Example They also cancelled all the special privileges of the many nobles and clergymen they felt were clogging up the system. They then looked at what the Americans had done with their Declaration of Independence from the U.K. in which they had tried to give equal rights to everyone. The French basically copies a lot of this and the Assembly published the Declaration of the Rights of Man and of the Citizen. This didnââ¬â¢t have any legal effect, but it was supposed to guide the government in making a new constitution. In the new document, all citizens are supposed to be guaranteed the rights of ââ¬Å"liberty, property, security, and resistance to oppression.â⬠The Declaration argues that the peoplesââ¬â¢ need for laws comes from the fact that ââ¬Å"...the exercise of the natural rights of each man has only those borders which assure other members of the society the enjoyment of these same rights.â⬠So the declaration sees law as a kind of ââ¬Å"expression of the general will,â⬠intending to promote equality of rights and to stop ââ¬Å"actions harmful to society.â⬠This was popular with many groups of people who had been disenfranchised under the old system and were looking for a big change which would give them more political power and reduce their tax rate. Previously the nobles had all the power and all the money; people were fed up and wanted things to be more equal. They felt they were a group that could no longer be trampled on by the upper classes, and that they h ad individual rights and should be able to be active French citizens. Two branches of politics can be seen to come out of this period. In the firstââ¬âthe American modelââ¬âwe can see people respecting individual rights and power devolved from government. In the second model we can see a sort of radicalism that destroys the old order and replaces it with a new radical order that wants everyone to be completely equal. This is the basis and foundation of Communismââ¬âmany of whose

She says that she had to squeeze her work time, which served as her recreation to be with the kids at home, as her husband could not manage the kids alone. ââ¬Å"...so I asked if I could just come to the store during the week...â⬠(Ladies Home Journal, pg 2). Another challenge that women experienced was when the children fell ill. They felt they would be blamed for the illnesses. ââ¬Å"...so I had exposed fifteen children to measles, and I was not the most unpopular mother in the neighbourhood...â⬠(Pg 3) On the other hand, the richer women boasted of easier work handling of the house chores as they were introduced to machines like the hoover and the ââ¬Å"full kitchenâ⬠accessories (Primary source pictorial, page 2 and page 5).In general, women found themselves caught between house chores and their leisure, which they often chose to fore go. In as much as the parents and social scientists of the day experienced anxiety over the emergence of a separate teenage culture, the business community took this to their advantage and produced more goods that would fit in the teenagers lifestyles. The increasing ââ¬Å"teen marketâ⬠was directly proportional to production and sales by the companies (The Teenage Consumer, Life 1959. Pg 2). Teenagers no longer fancied bikes and dresses; instead they surrounded themselves with millions of photographs, television sets and cameras, much to the disbelief of the parents who thought such as luxuries at their time (The teenage consumer, Life Magazine. Pg 1). As illustrated in "Life Magazine", (August 31st, 1959, Pg 1), previously the businessmen mainly ignored the teenage market. However, they later began to pump more resources in line with the teenage demand. A case example of a 17-year-old Suzzie is given; a route that apparently teenagers would

The interest of the reader Throughout Essay Example for Free
The interest of the reader Throughout Essay In the story the Adventure of the Speckled Band a girl dies mysteriously. No one knows how she died, and her sister, fearing for her own life, goes to see Sherlock Holmes. She tells him all about the mysterious death of her sister and he goes to her home, with his assistant Dr Watson, to investigate. They stay in the room that the girl was in when she died and discover that theres an air-vent that runs from the stepfathers bedroom to the girls bedroom. The bed is bolted to the floor so it cant be moved away from the wall and theres a bell-pull by the bed that isnt connected, its fake. In the end they discover that the stepfather wasnt happy about the girl getting married because he didnt want her husband to get her money so he killed her using an Indian Swamp Adder the Speckled Band. As the sister of the dead girl was getting married, the stepfather moved her into her sisters bedroom, next to his, and tried to kill her before she married. The relationship between the stepfather and the two women was not the best of father-daughter relationships. They hated him and he didnt exactly like them because theyd inherit his money when he died. The mystery was solved and his plan backfired, the snake bit him and killed him instantly, before he had a chance to kill the daughter. Conan Doyle keeps the reader in suspense throughout the story. He does this by giving the reader clues, which dont make sense when theyre first given, and lead you down the wrong path completely. These are called red herrings, something that make you think one thing when its actually something completely different. In the end all the clues Conan Doyle has given make sense. The story keeps the reader in suspense because its a mystery story. As its to do with a murder, that makes the story more exciting and makes you want to read on and find out what actually happens at the end and what conclusion Sherlock Holmes comes to at the end and whether or not its correct. I thought this story was a bit boring, as it was 19th century. Back then it would probably have been thought to be a very good story, but I prefer more up-to-date stories. I didnt find it that bad or that good. Im glad it wasnt too long because I would probably have got very fed up of it if it had gone on and on and on. It gave you all the facts and information you needed and didnt go on and on about one thing for too long. It was kept short and sweet. In that way I thought it was ok. In the story the stepfather is a doctor and worked over in India but got sent back to England because of his violent temper, as he struck a person for something that wasnt their fault. The doctor had animals imported from countries hed worked in, e. g. ) India. He kept a cheetah, an orangutan, which everyone knew about in the village, and an Indian swamp adder, (the speckled band), which no one except the doctor, knew about. In the story the doctor rents out some of the land he owns to some gypsies. At first when people hear about the mysterious death at the manor, some think that it was the cheetah or the orangutan that had killed Julia, and some think the speckled band was a bandanna that the gypsies wore and that it was one of them that had murdered her. Others didnt know what to think. After some investigating, Sherlock Holmes solved the mystery, with the help of his assistant, Dr Watson, and the story had a happy ending. Helen, Julias sister got married and the doctor, her stepfather, got killed by the swamp adder he was going to use to kill Helen like he did Julia.

Apathy :: essays research papers
As you wait to cross the street, a blind man is standing in front of you. Without warning, he begins to cross the street even though the light has not changed in his favor. He seems to be in no danger until you see a car about a half mile away speeding towards him. Totally unaware of the situation, the man continues walking across the street. As you and many others watch in horror he is struck by the car. Although every single one of you had plenty of time to rescue him, you just watched, hoping that someone else would do it. After all, you don't know him so it's really none of your business. This is what is referred to as "bystander apathy". People close enough to see, hear and possibly touch one another are socially distant and totally indifferent to the fact that another human being may be dying, in immediate danger, or asking for help. This extremely sad urban problem is just that- a problem of cities. The likelihood of this occurring increases with the number of people present and it is probable that there will be many people to witness an event when it happens in high density cities. Urban sociologists, social psychologists, and criminologists have argued for years that the size of cities is directly related to the amount of "social pathology" they contain. The legal consequences are not severe. Unless an individual is a certified medical doctor, they have no obligation in Alberta to help anyone in need. So generally, they don't. The personal consequences may be more severe. Feelings of guilt and regret may follow an event, especially if it ends fatally or if the individual feels that they could have done something significant. Because of this, people attempt to convince themselves and others that they were justified in their inaction because "it wasn't their place", "I didn't want to do it alone", or "I didn't want to get involved." Excuses like this often stem from fears of being seen as abnormal, possible physical harm, public embarrassment, possible involvement in police procedures, lost work days and jobs, and other dangers. Urban people are very concerned with the way they appear to others. Anything that may separate them from the "in-group" of society is usually seen as too risky to take part in. And strangely enough, helping people in need is seen as one of these risks.

Employee Law
Project Summary Employment Law The employment relationship Is a contractual one between an employer and a worker. The worker may be either an employee or an Independent contractor. Distinguishing between the two is very important. It has an effect on compensation, benefits, harassment, family leave, workers' compensation, unemployment insurance, and discrimination, (Moran, 2008, p. 3). In an employment relationship, authority is conveyed by an employer to an employee. Deciding what kinds of authority and how much authority to grant are important issues for employers to resolve, (Moran, 2008, . ). Inherent in every employment relationship is the employee's duties of loyalty and good faith and the employer's duties to compensate and maintain a safe working environment. Violations of these duties give rise to contractual and tort liability. A contract Is a legally enforceable agreement. A tort Is a private civil wrong. Tort liability encompasses assault and battery, defamation, Invasion of privacy, and negligence. The key to an employers responsibility Is whether the tort was committed within the scope of employment?in other words, ââ¬Å"on the Job,â⬠(Moran, 2008, p. 3)Employers may attempt to employ restrictive covenants, also known as nincompoop or nondisclosure agreements. These agreements are used to protect the employer's business against theft of trade secrets, stealing clients, and competing against the former employer. Courts generally do not like to restrict people from working, but the courts will enforce these agreements where they are voluntarily signed and designed to protect the business from unfair competition, (Moran, 2008, p. 3). The purpose of recruitment and selection is to obtain the best possible workers for a business.Discrimination is permissible with respect to selecting candidates based on interpersonal relations, communication skills, training, and education. It Is not permissible with respect to suspect classification such as race , religion, gender, age, disability, and national origin,â⬠(Moran, 2008, p. 37). Because employees are valuable assets to a business, employers must be able to choose those employees who will perform the best work for the business. Education, training, communication skills, and interpersonal relations are key qualities that employees must possess to help a business be more successful, (Moran, 2008, p. ). The easiest way to discriminate against individuals is to do so in the recruitment and selection process. Employers may use a myriad of methods to evaluate an individual and his or her particular traits. Testing, interviews, writing samples, demonstrations, and role-playing are a few examples, (Moran, 2008, p. 37). If these methods are job-related, then the employer has every right to use them. ââ¬Å"What an employer may not do is discourage potential candidates who belong to a particular suspect classification as defined by Title VII of the Call Rights Act, the Age Delimitat ion In Employment Act, and theAmericans with Deliverables Act,â⬠(Moran, 2008, p. 37). The selection process has become a complicated procedure for employers, (Moran, 2008, p. 67). They must inappropriate questions that can be inferred as being discriminatory. Employers must recruit from a diverse pool of candidates. Employers must keep accurate records of these candidates, such as who applied and who was hired. Employers must establish Job-related criteria necessary for promotions. Employers must perform background checks on employees to guard themselves against negligent hiring, but these checks are limited to activities or criminal convictions that are Job elated,â⬠(Moran, 2008, p. 67). Policies with regard to nepotism and promoting from within should also be drafted by the employer. The selection process is a daunting but necessary undertaking for the employer. As most of us know, it is an equally stressful experience for workers. Arbitration is a form of alternative dispute resolution where two sides look outside the court system to resolve a conflict, (Moran, 2008, p. 157).In arbitration, an impartial arbitrator listens to claims, facts, and testimony from both sides, then issues a decision. By signing arbitration agreements, employees typically waive their right to file lawsuits when they have a dispute with their employers. However, the obligation to arbitrate can vary. Some employers require all disputes to go to arbitration, while others designate arbitration for only certain issues. ââ¬Å"Bindingâ⬠arbitration is most frequently used in employment agreements, where both sides agree ahead of time that the arbitrator's decision will be final, with very limited basis to appeal, (Moran, 2008, p. 58). However, an arbitration agreement alone does not mean that employers can never be sued over an employment issue. State and federal regulators can still sue employers when employees file complaints against companies for violating discriminat ion, pay, or other laws. Once employees or former employees decide to enter into arbitration, there are three basic steps in the proceedings: preheating briefs, the hearing, and the arbitrator's decision. Preheating briefs allow the company and employees to present their views and describe their evidence to the arbitrator.During the hearing, both sides present their case to the arbitrator, which can include calling witnesses. Then the arbitrator makes a decision. Generally, employers do not take termination as personally as do employees. However, it can be a difficult process for both sides, especially if the employee believes that the discharge is wrongful. ââ¬Å"At-will termination protects the rights of employers to terminate employees,â⬠(Moran, 2008, p. 153). Therefore, employees must evaluate the evidence to discern whether it meets one of the public policy exceptions to the at-will doctrine.Employers must guard against compromising their protection under the at-will emp loyment doctrine and should not stipulate that employees will be discharged only for cause or list explicit seasons for discharge in an employment handbook or in conversation with an applicant or an employee, (Moran, 2008, p. 153). Rather employers should state that employees may be discharged at any time for any reason. Shortly after the conclusion of the Civil War in 1865, the Thirteenth, Fourteenth, and Fifteenth Amendments to the U. S.Constitution were adopted, (Moran, 2008, p. 171). The Thirteenth Amendment abolished slavery. The Fifteenth Amendment gave black men the right to vote. But, it was the Equal Protection Clause of the Fourteenth Amendment that laid the basis for equal rights in employment, (Moran, 2008, p. 71). The Equal Protection Clause basically states that ââ¬Å"all people are entitled to equal United States, in Please v. Ferguson, interpreted this to mean that separate but equal facilities would satisfy the Fourteenth Amendment requirement, (Moran, 2008, p. 171 ).Segregation persisted into the sass, but inroads began to be made in the mid-sass with the Brown v. Board of Education decision, which mandated integration in public schools, (Moran, 2008, p. 171). This decision had a reverberating effect throughout society. In 1964, Congress passed the Civil Rights Act to legislate integration in schools, housing, restaurants, transportation, shopping, and employment. Title VII of the Civil Rights Act speaks to employment, (Moran, 2008, p. 171). It prohibits discrimination because of religion, race, color, sex, and national origin, (Moran, 2008, p. 171).There are two main types of discrimination: disparate impact, which is discrimination against a class of people, and disparate treatment, which is discrimination against an individual, (Moran, 2008, p. 171). The key to establishing an affirmative action plan is to obtain the commitment of management, Moran, 2008, p. 199). Once committed, management can emphasize its importance and lead by example. An assessment must be made of the number of women and minorities and their current status within the organization. This data will prove invaluable as a benchmark against which the program's progress can be measured, (Moran, 2008, p. 99). Once the problem areas are identified, then recruitment and promotion issues must be addressed. A critical look at the current methods utilized must be taken, and a plan must be instituted to remedy its deficiencies. To bolster acquirement, notification should be sent to the placement office of schools with significant or exclusive women or minority populations. Women and minority organizations can also be advised of the need for prospective candidates. Advertisements in newspapers, magazines, radio, and television designed for women and minorities will enable a company to tap into that particular circle, (Moran, 2008, p. 99). Company tours for students and community groups are also beneficial. ââ¬Å"Relying solely on referrals and traditional rec ruitment techniques will only reinforce discrimination,â⬠(Moran, 2008, p. 199). Career counseling to direct women and minorities toward career paths and training programs to help them realize these accomplishments must be created or embellished. The fact that counseling and training programs exist is not sufficient. They must be made available or specifically developed with women and minorities in mind.Job descriptions must also be perused for possible barriers against women and minorities, (Moran, 2008, p. 199). If found, the descriptive narration must be rethought. All requirements must be Job- related. Any that are not should be eliminated, especially unnecessary education or experience; otherwise, discrimination will continue. Testing should also be restricted to when it is absolutely necessary and its reality and Job-relatedness can be proved, (Moran, 2008, p. 199). The assignment of grade levels to Jobs must also be reviewed for bias in favor of men, (Moran, 2008, p. 199 ).If discovered, such bias must be readjusted. Interviewers must be indoctrinated to no longer believe that women and minorities can perform only certain Jobs ââ¬â those involving routine ministerial tasks, (Moran, 2008, p. 199). They must avoid asking women and minorities personal questions about marital status, other sources of income, number of children, criminal record, and other issues that are not Job-related and are not routinely asked of white and in-house rules and regulations must be redrafted to be gender-neutral, both in written communications and pictorials,â⬠(Moran, 2008, p. 199). Sexual harassment is defined as (1) a sexual advance or request for sexual favor made by one employee to another that is unwelcome and not consented to; and (2) touching, Joking, commenting, or distributing material of a sexual nature that an employee has not consented to and finds offensive,â⬠(Moran, 2008, p. 89). Although the court- appointed test for determining what consti tutes sexual harassment is a reasonable person standard and what is reasonable may vary depending on the work environment, it is the purpose of this policy on sexual harassment to avoid litigation, not to win lawsuits.Therefore, employees are forewarned that the use of certain terms may give rise to a woman's filing a sexual harassment complaint and are therefore prohibited, (Moran, 2008, p. 289). If a complaint is filed with the company's human resources department on any of these allegations, it will be investigated immediately, (Moran, 2008, p. 289). The investigation shall consist of questioning the complainant, alleged perpetrator, coworkers, superiors, and subordinates, (Moran, 2008, p. 89). If a determination is made that a valid complaint had been issued against an employee, that employee will be entitled to a hearing to which he or she may be assisted by outside counsel. If a conclusion is reached that the conduct complained of meets one of the aforementioned criteria, then the employee shall be dismissed forthwith, (Moran, 2008, p. 289). Furthermore, the victim will be afforded counseling services, if needed.Every effort will be made by the company to aid the victimized employee in overcoming the emotional trauma of the unfortunate ordeal, (Moran, 2008, p. 289). Finally, the company will sponsor in-house workshops explaining this policy on sexual harassment, warning employees against engaging in it, and encouraging those affected by sexual harassment to come forward with the details of their encounter with it in order for the company to investigate and resolve the dilemma and service the needs of the victimized employee, (Moran, 2008, p. 289).The Americans with Disabilities Act requires employers having 1 5 or more employees to refrain from administrating against any individual who has an impairment that limits major life activities, such as impairment to sight, speech, hearing, walking, and learning, (Moran, 2008, p. 389). Also included are people w ith cancer, heart conditions, AIDS, and disfigurement, as well as people recovering from substance abuse. The forerunner of the DAD was the Rehabilitation Act of 1 973. It prohibited disability discrimination in federal employment and with federal contractors.The percentage of disabled workers who are unemployed is much greater than that of the general population, (Moran, 2008, p. 08). Public access and specific Job accommodations have gone a long way to aid the gainful employment of many of the disabled. Encouraging a change in the mind-set of employers remains a formidable task. Many employers view disabled applicants as inferior to others. They represent an additional worry employers do not need. However, with reasonable accommodation, many disabled employees have proven to work as effectively as other workers because their disability has been alleviated, (Moran, 2008, p. 08). They are operating on a level playing surface with the rest of the work population. Collective bargainin g is the negotiation process undertaken by a union on behalf of a contract after the resolution of labor issues,â⬠(Moran, 2008, p. 420). The contract, known as the collective bargaining agreement, is binding on all union members. The advantage of collective bargaining is that the union has greater bargaining strength than an individual employee would have in attempting to negotiate the best possible deal, (Moran, 2008, p. 420).The Occupational Safety and Health Act of 1 970 (OSHA) was designed to set forth a standard that would provide for the safety and health of employees while on the Job, (Moran, 2008, p. 450). Employers are required to provide a place of employment free from occupational hazards. Employees are required to follow rules and regulations established to promote their safety and to use equipment designed to ensure their safety, (Moran, 2008, p. 450). Permanent standards are the standards originally introduced when OSHA was created as well as standards promulgate d thereafter, (Moran, 2008, p. 452).The latter are referred to as National Consensus Standards. When OSHA develops a new standard, it is published in the Federal Register, (Moran, 2008, p. 452). The public, especially employees, has 30 days to request a hearing. If requested, notice of a public hearing will be made. After the hearing, OSHA must publish the standard incorporating the changes, if any, and the date of its commencement, within 60 days. The Secretary of Labor must explain the need for the new standard, or else it will be null and void. He or she may delay the date of its commencement. In one case, a delay of 4 years was imposed.

Patterns in Strategy Formation Essay
A critical summary of the article ââ¬Å"Patterns in strategy formationâ⬠written by Henry Mintzberg, published in Journal Management Science Vol. 24, No. 9, (1978) A short overview The paper,â⬠Patterns in strategy formationâ⬠, outlines a new kind of description to the much misunderstood process of strategy formation in organizations. After giving a short summary of the theme, the author, Henry Mintzberg, describes the term ââ¬Å"strategyâ⬠and shows how the definition leads to the choice of a research methodology. Following this, he details the four steps of research methodology. With to completed, major studies about two organizations (Volkswagenwerk and the United States government in Vietnam) Mintzberg analyzes three central themes. The first is that strategy formation can be viewed as the interplay between a dynamic environment and bureaucratic momentum, with leadership mediating between the two. Second, that strategy formation over periods of time appears to follow distinct regularities, for example life cycles or change-continuity cycles within life cycle. And third the study of the interplay between intended and realized strategies may be central to the strategy formation process. Definition of strategy and the research methodology In the first section of the paper, Mintzberg describes the term â⬠strategyâ⬠. Strategy is generally defined, whether in game, military or management theory, as a deliberate, conscious set of guidelines that determines decisions into the future. In common terminology, a strategy is a plan. Mintzberg illustrates that defining strategy as a plan is not sufficient, because if strategies can be intended, surely they can also be realized. A definition that encompasses the resulting behavior is therefore required. The author proposes to define strategy in general as a pattern in a stream of decisions. To clarify this definition of strategy, he introduces a few illustrations. For example, when Picasso painted blue for a time, that was a strategy â⬠Blue Strategyâ⬠. This definition of strategy necessitated the analysis of decision streams in a organizations over time periods to detect the development and breakdown of patterns. Therefore Mintzberg subdivided the analysis of the studies into four central steps. 1st step: Collection of basic data. 2nd step: Inference of strategies and periods of change. 3rd step: Intensive analysis of periods of change. 4th step: Theoretical analysis. After giving a brief review of the periods of strategy in two organizations, using the terminology of the research, the author comes to the core of the paper, which is the presentation of some theoretical conclusions about strategy formation. Strategy formation as the interplay of environment, leadership and bureaucracy Mintzberg outlines strategy formation in most organizations as the interplay of three basic forces revolving around the dynamic environment that changes continuously but irregularly, organizational management or bureaucracy that attempts to stabilize the actions of the organizations whilst operating in the dynamic environment, and leadership of the organizations whose role is to mediate between the two forces. From this point of departure, the author provides a definition of strategy and of strategic change. â⬠Strategy can then be viewed as the set of consistent behaviors by which the organization establishes for a time its place in its environment, and strategic change can be viewed as the organizationââ¬â¢s response to environmental change, constrained by the momentum of the bureaucracy and accelerated or dampened by the leadershipâ⬠. Mintzberg illustrates, that the two organizations (Volkswagenwerk and U.S. government in Vietnam) are stories of how bureaucratic momentum constrains and leadership dampens strategic change. In 1965, for example, when the United States government escalated the Vietnam war in a way that made the escalation inevitable, the new leadership, named Johnson, dampened the strategic change, under the environmental and bureaucratic pressures. Also in 1960, when action was needed in the face of an increasingly changed environment, the central leadership of Volkswagenwerk was not forthcoming. Patterns of strategic change According to Mintzberg, patterns of strategic change are never steady, but rather irregular and ad hoc, with a complex intermingling or periods of change, continuity. Even so, he recognizes some patterns in strategy formation that may enable organizations to understand better their strategic situations. The first pattern is the life cycle of an overall strategy, based on four phases: conception, elaboration, decay and death. The author illustrates that the case of Vietnam represents the classic strategic life cycle. The second pattern is the presence of periodic waves of change and continuity within the life cycle. This second pattern suggests that strategies do not commonly change incrementally. Rather, change takes place in spurts, each followed by a period of stability. Mintzberg notes, that nowhere is the change-continuity cycle better demonstrated than in the stepwise escalation of the Vietnam metastrategy. According to the author, the reason for the periods of change and continuity is that human do not react to phenomena continuously, but rather in discreet steps, when changes are large enough to be perceived. In a similar manner, strategic decision processes in organizations are not continuous, but irregular. Based on both studies, Mintzberg notes, that there are dangers in incremental changes. He argues that strategy-makers seem prepared to assume positions in incremental steps that they would never begin to entertain in global ones. On the other hand, global change is very difficult to conceive and execute successfully. According to the author, this is perhaps the strategy-makerââ¬â¢s greatest dilemma. The danger of incremental changes versus the difficulty of global changes. Interplay between intended and realized strategies The author identifies two kinds of strategies: intended and realized. He illustrates, that these two can be combined in three ways: Intended strategies that get realized, which are called deliberate strategies (e.g. the Volkswagen strategy of 1948 to 1958). Intended strategies that do not get realized, which are called unrealized strategies (e.g. Kennedyââ¬â¢s intended strategy of 1961 of advising the Vietnamese). Realized strategies that were never intended, which are called emergent strategies (e.g. the U.S. strategy of finding itself in a fighting instead of advising role). Furthermore, Mintzberg argues that it is possible to find a number of other relationships between intended and realized strategies, such as intended strategies that, as they get realized, change their form and become emergent; emergent strategies that get formalized as deliberate ones; or intended strategies that get overrealized. This view challenges the tenets of planning theory, which postulates that the strategy-maker formulates from on high while the subordinates implement lower down. Mintzberg argues that this dichotomy between strategy formulation and strategy implementation is a false one under certain conditions ââ¬â e.g. the formulator isnââ¬â¢t fully informed or the environment isnââ¬â¢t sufficiently stable -, because it ignores the learning that must often follow the conception of an intended strategy. According to Mintzberg, another important point is that the formalization of an emergent strategy as the new, intended strategy is hardly incidental to the organization. The author states that the very act of explicating an implicit strategy changes fundamental the attitude of the bureaucracy and of the environment. He further argues that the very fact of making a strategy explicit provides a clear and formal invitation to the bureaucracy to run with it. But the author also notes that sometimes it can be risky to make strategy explicit, notably in an uncertain environment with an aggressive bureaucracy. He makes the point that the strategy-maker may awake one day to find that his intended strategy has somehow been implemented beyond his wildest intentions. It has been overrealized. Conclusion and critique on the paper In my estimation, the paper â⬠Patterns in strategy formationâ⬠is very well-written. The author, Mintzberg, first describes what the paper will be all about. After that, he introduces the theme, strategy as a pattern in a stream of decisions, and shows how this definition leads naturally to the choice of a research methodology. After that, he explains the four steps of the analysis he will use to reviews the major periods of two organizations (Volkswagenwerk and U.S. government in Vietnam). By using these major studies he arouses the readerââ¬â¢s interest and creates a fundamental basis to examine and prove aspects, that strategy formation can be viewed as the interplay of environment, bureaucracy and leadership, that that strategy formation appears to follow distinct regularities and that the study of the interplay between intended and realized strategies may be central to the strategy formation process. Furthermore, he admits that this studies constitute a limited data base, but they do call into question a number of assumptions about the process of strategy formation in organizations, e.g. that a strategy is not a fixed plan, that dichotomy between strategy formulation and strategy implementation is a false one under certain common conditions or that it can sometimes be risky to make strategy explicit. Some general conclusions suggested by these studies are complex and very difficult to understand but, nevertheless, the well-disposed reader understands the approach. This is mainly because, he explains his statements on this two studies closely. To sum up, the paper is well-structured and of a good concept. Furthermore, the paper ties in with very important and interesting research-fields in strategy management.

Ozus Tokyo Story A thematic and cinematic analysis of post World War II Japan essays
Ozus Tokyo Story A thematic and cinematic analysis of post World War II Japan essays Yasujiro Ozu's cinematic classic "Tokyo Story" portrays the essentially divided nature of old and young individuals, even within the same family, that existed in Japan during the immediate aftermath and cultural shift that occurred as a result of that nation's loss of World War II. The film depicts a mother and a father who temporarily travel from the rural, Japanese countryside and their old way of life to visit their urban children in Tokyo during this period of Japanese history. The general title of "Tokyo Story" suggests the generalized nature of the story in modern Japan. The film was made in 1953 and depicts recent post-war Japan, shortly after the peace treaty ending the ear and the reconstruction of the Asian nationthus, it looks back on a recent period of history, not from afar, but with a critical and often sorrowful eye as to what was recently lost, and examines how recent events have taken turn for the worse in terms The mother and father visit children whom are extremely ungrateful of the sacrifices made by their parents for their welfare in. The children do not reject their parents for coherent ideological reasons that directly correlate to World War II. Rather, the children are show to feel, by and larger, that they are too busy to get to know their aging parents any better. Their contemporary, urban lifestyles do not mesh with their parent's slower rhythms and manners. The past filial sense of obligation is dead in Japan, suggests the film. The sense of responsibility children should feel for their parents is dead, and only sorrow is left behind. However, certain connections between old and young, however tenuous remain, at least in some form. The connection between mother-in-law and daughter-in-law is one such connection. For instance, the mother of the tale spends a night of emotional sharing and intimacy with the widow o...

Every IB Biology Past Paper Available Free and Official
Every IB Biology Past Paper Available Free and Official SAT / ACT Prep Online Guides and Tips When you take the IB Biology SL or HL exam, you'll probably be stressed out no matter what. But having seen a past paper beforehand will be a huge advantage: you'll know the format of the test cold and be used to the length and style of the test. In this article, I will at least try to get you familiar with the exam format by exposing you to IB Biology past papers, both free and paid. I'll also share strategies on how best to use these IB Biology tests for your own exam prep. Where to Find Free Past Papers In the last few years, IBO has gotten tough on illegal uploads of past papers, with the result that many sources are no longer available. Unfortunately, IBO has yet to provide any free sample Biology papers (SL or HL) on its website (although we'll be sure to update this article if and when that does happen). Because of this, while you might find some results if you search around online for past IB Biology papers, it's difficult to know if they're real past papers (illegally uploaded) or unofficial (ones created from scratch by students for practice). You should be very wary of any unofficial IB Biology papers you find. I DO NOT recommend using them, as they may be very different from the actual IB Biology exam. Where to Find Paid Tests The Follet IB store sells digital versions of the IB Biology SL past papers and IB Biology HL past papers from November 2015 to November 2018. This is the only safe place to get IB Biology past papers to download. Each paper and each mark scheme cost $3, so one full exam (including paper 1, paper 2, paper 3, and the mark scheme) will cost you about $18. Buying all of the past papers and mark schemes from 2015 to 2018 is costly, so we recommend just purchasing the two most recent complete past papers (May and November 2017). These tests will be the most similar to what you'll be tested on, particularly since there was an IB Biology syllabus change as recently as 2016. Plus, for most students, two tests will be plenty of practice. 3 Tips to Use IB Biology Past Papers Effectively Each IB Biology practice test will take 3 hours for SL or 4.5 hours for HL, so it's crucial that you get the most out of each test (since you will probably not have time for very many of them). Here are critical strategies to keep in mind when you're taking the tests: #1: Take Papers 1 and 2 In One Sitting, if Possible IB Biology SL and IB Biology HL papers 1 and 2 are given back to back, forcing you to write for 2 hours for SL and 3 hours and 15 minutes for HL. You need to build up endurance, so you don't make careless mistakes when you are exhausted at the end of paper 2. By taking the IB Biology practice exam in one sitting, you build up important endurance for the real papers. If you don't have time in your schedule for a 2-hour or 3-hour 15-minute session, then splitting the papers up over a few days is fine. Just make sure you follow the next rule: #2: Keep Strict Timing on Each Paper With a Timer It is vital that you get used to the timing pressures on the IB Biology papers. Here is the time allotted for each paper: IB Biology SL IB Biology SL Paper 1- 45 minutes IB Biology SL Paper 2- 1 hour 15 minutes IB Biology SL Paper 3- 1 hour IB Biology HL IB Biology HL Paper 1- 1 hour IB Biology HL Paper 2- 2 hours 15 minutes IB Biology HL Paper 3- 1 hour 15 minutes In this time frame, you need to finish: IB Biology SL SL Paper 1: 30 multiple-choice questions SL Paper 2: 4 short responses and 1 essay question (you choose between 3 options) SL Paper 3: 6 short response questions that each can have between 2-5 parts IB Biology HL HL Paper 1: 40 multiple-choice questions HL Paper 2: 4 short response questions that each can have between 3-10 parts and 2 essay questions (you choose between 4 options) HL Paper 3: 7 or more short response and essay questions (varies based on the options that you covered in your class). Do not give yourself even two extra minutes during your practice- this can allow you to answer more questions and improve your IB exam score substantially. You want to use these practice tests as reliable indicators of your real IB Biology score, not as a way to falsely boost your sense of progress. #3: Review Your Answers From Your Practice Test At the end of every practice exam, make sure you review every mistake you made, and every question you were unsure of. If you skip this step in the process, you're not going to learn from your mistakes, and you'll continue making them on the next tests. You should spend at least 1.5 hours reviewing every full practice exam. This may feel like a lot of time, but emphasize quality of learning over quantity of learning. I'd rather see you take two exams with detailed review than five exams with no review. Whatââ¬â¢s Next?

In order to precisely and most apparently highlight the major factors in terms of promoting nutritional and physical development of the children, the different areas of this report would be assessed in accordance with the guidelines of Understanding by Design (UbD) approach. The nutrition and physical activity curriculum incorporates the following stages: Significance of nutrition and physical activity and their role for developing children health Comprehensive health and physical education need as per the standards of NJCCCS (New Jersey Core Curriculum Content Standards) for promoting good health for the children Identify the desired results in terms of learner outcomes and goals Create ââ¬Å"essential questionsâ⬠that will focus upon the work co ncerning the key concepts, themes, issues and problems of the topic Design effective assessment plan in accordance with the promotion of good health for the children Design effective learning experience or course which can enable the child care settings (parental and institutional) to equip the students with skills, proficiency, knowledge as well as understanding. b. State the Appropriate NJCCCS it Addresses The New Jersey Core Curriculum Content Standards (NJCCCS) can be duly considered as one of the major frameworks for educating a child relating to the development which has been formed by the New Jersey State Board of Education during the year 1996. The NJCCCS framework tends to incorporate adequate guidelines and principles that apparently define the major learning process for the students to accomplish desired education or the learning outcome (State of New Jersey Department of Education, n.d.). The guiding principles underneath the NJCCCS address various aspects towards improv ing the curriculum in terms of developing child educational settings. Additionally, the principles of this framework also tend to incorporate adequate measures associated with promoting good health and wellbeing of each student within different educational institutions. In this regard, nutrition and physical activity is also a major consideration of the NJCCCS framework which highly focuses on improving the dietary and physical education for each child within any educational, healthcare and parental settings. Furthermore, the framework also ensures to streamline the practices concerning the wellness and good health of the students within the educational settings and confirms to develop physical, psychological as well as educational growth of each child (The State of New Jersey, n.d.). c. Identify the Desired Results in terms of the Learner Outcomes and Goals Identifying desired results can be regarded as one of the primary and initial stages of UbD approach ensuring to efficiently u nderstand the students regarding the significance of nutrition and physical activities. In this context, the identification of desired results in terms of learner outcomes and goals has been explained in the following discussion. Established Goals The essential factors concerning nutrition and physical education for the children will be focused in terms of clearly identifying the desired results of the unit. Therefore, in the major stage of designing the unit, certain realistic goals in accordance with the NJCCCS

The Competition & Consumer Act of 2010 Replaces Trade Practices Act of Essay
The Competition & Consumer Act of 2010 Replaces Trade Practices Act of 1974 - Implications and Significance - Essay Example The Trade Practices Act of 1974 has always been an integral component of Constitution of Australia as a guarantor of purchaser. Background & Evolution: The need for the formation of a business law was felt during the British rule in Australia in the first half of the 19th century however, at that time all the companies were governed by ââ¬Å"English Company Act of 1862â⬠. In the first half of the 20th century Federal Parliament of Australia formed "foreign corporations, and trading or financial corporationââ¬â¢s formed within the limits of the Commonwealth" and the Small Business activities were left within the domain of the state and the particular territories in a geographical location. In the year 1961-62 for the first time in the history of Australian Business Law State Legislation and Commonwealth Legislation formed ââ¬Å"A Uniform Companies Actâ⬠. The year 1965 Trade Practices Act crafted a ââ¬Å"Commissioner of Trade Practices and a Trade Practices Tribunalâ⠬ to scan trade accords and performances. However, this act was ephemeral and finally the High Court in Australia had to annul the aforesaid act due to ââ¬Å"Constitutional Difficultiesâ⬠and replaced the same with Restrictive Practices Act in 1971. The Trade Practices Act of 1974 was endorsed to deal with issues relating to Consumer protection was exclusively in charge of looking after the interests of the consumers at all levels however, the Legislation regarding fair trading and other issues external to Trading Corporation remained within the realm of respective states and territories. Thus, The Trade Practices Act 1974 became the decisive Legal entity governing the trade policies to ensure the welfare of the consumers. Finally the Trade Practices Act 1974 was replaced by ââ¬Å"Competition and Consumer Act of 2010.â⬠(History of Business Law, 2010) The Trade Practices Act 1974 Hence the primary task of the Trade Practices Act was to ensure healthy competition without compromising the interests of the consumers. Fair Trading was the benchmark to analyze the role of big companies concerning the protection of consumers. From patrons, merchants, contractor and traders they all fall within the ambit of the Act. In short it included every facets of market place. Regulation of trade through Price monitoring is one of the key ingredients for accomplishing the consumer protection. Other means for safeguarding the interests of the consumers could be ensuring product security, labeling of products and finally restricting ââ¬Å"unjust marketplace practicesâ⬠. The Competition & Consumer Act of 2010 January 2010 marked the New Year with a new set of laws and legislations that was passed for safeguarding and protecting the rights of the Consumers as well as business groups. If one has to carefully analyze and understand the special benefit of this new law that has replaced the former Trade Practices Act, one can draw two main benefits which are evident. Special Significance of the Act: First it accommodates and accepts the nationwide agreed sets of protections on a consumer known as Australian Consumer Law (ACL). According to this new Act there would be a single uniform Consumer Law all over the country. Hence it would relieve the burden on the business enterprise to abide by the various interââ¬âstates rulings. The consumer on the other hand would feel less discriminated against as there would be a uniform law safeguarding and

American National Government Essay Example | Topics and Well Written Essays - 500 words
American National Government - Essay Example The Supreme Court had never occasion to rule on freedom of speech issues until opponents of conscription during WWI were prosecuted for sedition. These cases established that speech that presented as "clear and present danger" to the government could be prohibited. This definition has remained the court's operative principle in such cases since that time. Since cases began to be brought before the court in the 1970s concerning campaign financing, the Court has consistently refused any limitation on the right of candidates to spend money, but just as consistently allowed the strict limitation of direct political contributions (so that, for example, an extremely wealthy individual could not single-handedly finance the campaign of any candidate but himself). The Supreme Court has always held that flag burning, precisely because of it unpopular and wildly politically inflammatory character, is protected speech. a. push: A push pool is a sort of telemarketing campaign disguised as a telephone poll in which the political operatives call potential voters and ask them leading or unfair questions meant to alter their political views. b.

A Critique Of Nancy Chodorow
A Critique Of Nancy Chodorow In Nancy Chodorows Family Structure, and Feminine Personality it is argued that care, development and socialization of children and females is largely rested upon women, and therefore provides the basis on gender personality development within males and females; but from the perspective of Margret Mead and her book Sex and Temperament this fails to account for separating the European views of male dominance, and also the role of the male in early development of the children, and the socialization of females. In the conclusion of Meads book she entered the idea that children school yard teasing, and their taught early gender roles were partially to blame for boys to perpetuate male dominated roles, and even the young girls themselves were to blame for furthering this ideology. Chodorow continues on mentioning mother/daughter relationships, and of double identification, but fails to account for malleability as well. In these mother/daughter relationships Chodorow continues to link this relationship as paramount to the gender socialization of the sexes. It is my belief that Mead would be superior in ultimately and authoritatively speaking on the basics of gender development in the sexes, due to her studies of different cultures. With Chodorow she continually speaks from the perspective of her native western nuclear socialite development, and only academically mentions other cultures which so happen to be possibly more developed towards the ways of the western world. The ability of being able to draft from a larger pool of culture that Margret Mead did made it possible to draw conclusions, form a basis and gave the ability leave out the Western world perspective allows the reader to conclude to similar opinions as Mead had. When Chodorow speak in large part of the Western, or nuclear families, she was able to draw the reader to make conclusions out of familiarity or even to have close access to ask the opposite sex questions to meet the similar opinions. The problem with Chodorows formatting of her short article and conclusions rested far too great of weight on the mother perpetuating of the male dominated society, and that the absent father added to further influence on the development of young boys and girls. Mead was able to present to the reader that in three different and distinct cultures that gender identity was not based on Freudian sexual needs but social conditioning. Chodorow even suggests that the mother/daughter relationship promotes the mothers own challenges within her own social development was transgressed onto the daughter, forming the daughters basis of womanly gendered behaviors known in the western world was feminine behaviors. This was contrasted by Mead when she wrote about the Mundugumor, in which children of either sex were considered a hassle and needed to survive by their own means, therefore both male and female were only differentiated based on physiologic differences, and both sexes displayed Masculine and Feminine attributes. Mead presented terms such as social conditioning in which the society provided the bonds, or lack of, for gender identity. Chodorows accounts were formed of the western perspective, and therefore drew from a shallow pool of cultural intelligence. Chodorow left the reader to believe that male dominance was something inherent and passed from generation to generation, and that naturally passed on due to the dynamics of the heterosexual relationship of men and woman the devel opment of young children. Mead was able to counter this believe in the 1935s when she talked about the Tchambuli peoples, in where the women were dominant, and the providers of the family; much like the opposite of the western worlds common beliefs. With Chodorow leaving the inference that gender identity were based on the Freudian model of sexual development, continued because it is also passed generation to generation based on the mothers upbringing discredits that there is malleability in society. The western perspective on gender identities, and roles had to of evolved from somewhere. With Meads views of the different and primitive societies, we the readers are able to draw conclusions that societies are based on their surroundings and passed down. Cultural borders or other borders allow differences to the Western perspective of male dominance. Mead was able to smash the ideals, that women, because of physiological differences with man created masculine/feminine roles. But in fact made the roles subjective in context to what the rest of that society views are masculine/feminine roles. Chodorow alleges that because women have such hard and limited lives of child rearing, lack of career choices, and dominated by men mothers pa ss this down to their daughters perpetuating the male dominance. With male dominance Chodorow had to contort her theory of male being dominant and women perpetuating this practice by conveniently including the absent father. The absent father image was what Chodorow presented; child males must transition from the role of son-mother connection and more towards their remote father and take on a positional role. I believe from after reading the context of Meads book and how its presents different cultures proves Chodorows claims as false. If the absent father is absent, then how can his role be influenced onto the child whose father is in fact, absent. In this case, this bolsters Chodorows initial claim that mothers determine the gender roles of both sons and daughters. But according to Mead and the Mundugumor people, children were seen as a liability to the men, and therefore already sent in motion the social conditioning that followed. The Mundugumor men viewed the children as liabilities, could potential beat their wives, and their society in resp onse forced the framing an anti-children society. So in this one culture Chodorows claim is disproven because Mead directly illustrated men do have an active role, and even went on further explaining this point with just this one Papua New Guinea tribe. Mead in her conclusion of Sex and Temperament noted that in the western world, child gender development was continued in the school yard. Chodorows view was more limited in that she was attempting to bolster her view that women gender identities developed as based on the mother/daughter relationship. Chodorow did acknowledge that some external events could influence gender role/identities development. Mead noted very powerful school yard bullying in two examples of feminine behavior being taught or reinforced on females in particular. One example was the usages of the word tomboy. Mead went on to note that the term formerly encompassed acting like a boy, dress like a boy and things like that. Nowadays all girls have to do is act like boys quite quietly. At the core of Chodorows argue of gender development is that the mother/daughter relationship forges the ideals of femininity. This is also entirely of the Western gender perspective. But Chodorow states that the formation of female gender identity is through the socialization of her mother, in which is socialized in groups of women, and therefore has no need to reject this perspective unlike the males. With girls and women there is not fanaticising of roles, but direct identity and therefore easily transitions these feminine identities. Chodorow leaves the reader to infer that there could be biological reasons for gender identities, with the theory of the mother/daughter. This maybe the way how gender identity is perpetuating in the western world, but in terms of evolutionary, it isnt the methods these are roles based. Mead concluded with her studies that the social conditioning defined the roles of male and females, she also further concluded that what is masculine and feminine is relative and not based to sexual identity. Mead with her cross cultural research noted three different societies, one where men has the traditional to the western world feminine attributes (Tchambuli), another culture were the women were as aggressive as the western world men (Mundugumor), and a third culture were men and women were exact complete equals (Arapesh). With these findings Mead was able to conclude that the individual society dictated the society structure and the gender roles, and what was masculine or feminine. The reader could also infer that both the genders were responsible for advancing the sociality gender identities onto the youth further progressing their gender models. Gender identities have been researched by both Margret Mead, and Nancy Chodorow, and both have presented excellent ideas to the sociology of genders. Margret Mead was able to present views from three cultures unlike our own. Chodorow mainly presented on a culture like ours, with references to other modern developed cultures. Chodorow was able to speak extensively for the female perspective of how feminine behaviors are passed from mother to daughter, and gave some examples on the male gender development. Mead was able to present that genders were malleable, and therefore changed based on what that culture demanded the roles of males and females be. Mead illustrated that women were not born feminine, and men not masculine. But that those qualities had to be taught onto the different sexes and outside of physical differences that man and women were essentially the same. Chodorow illustrated that gender behaviors were forged based on the relationships of the children to the parents, and if the children could assimilate based of their sexual identity. But Chodorow failed to present how these roles were started and only talked about how that are perpetuated. Chodorow also failed to give some explanation as to how these role behaviors either evolved. This is why I still believe that Meads writings are a little more comprehensive on the discussion of the roles of genders, and the relativity of masculine/feminine behaviors.

Arthur Millers Death Of a Salesman Exposes Morals and Values of American Culture :: Death Salesman essays
Arthur Miller's Death Of a Salesman Exposes Morals and Values of American Culture Arthur Miller's play, "Death Of a Salesman" is a veryà à elaborate play that tells the story of a man's dream to achieve greatness from nothing. It almost seems to make fun of American society's competitive nature, "Imagine? When the mail comes he'll be ahead of Bernard again!" Willy(1215)à à à à à à à The title "Death Of a Salesman" leaves nothing to the imagination of how this play ends. Indeed this is a story about the noble, cowardly death of Willy Loman, a traveling salesman. Arthur Miller used the efficient idea of using flashbacks to allow the play to take place within a few days instead of years. Willy Loman as the central character, lives with his wife, Linda and has two sons, Biff (elder) and Happy. Willy Loman who is quite literally a "low man" has so many personality traits accurate to real life, this is no surprise since Miller based Willy's character on his uncle, Manny Newman. Miller said, "That homely, ridiculous little man had after all never ceased to struggle for a certain victory, the only kind open to him in society - selling to achieve his lost self as a man with his name and his son's name on a business of his own"à à à à à à Willy was defiantly in a struggle however, he was certainly not in a struggle to convince himself he was doing better than he really was, "I can park my car in any street in New England, and the cops protect it like their own." Willy (1165).à Willy Loman did not want to die, he went to Ben to seek approval of what he thought would please the family"...Ben, I want you to go through the ins and outs of this thing with me. I've got nobody to talk to, Ben, and the woman has suffered, you hear me?" Willy (1210) He also proved this with his many "near incidents" and the rubber pipe. According to "Suicide:The facts and myths" by Judi Marks, "Attempted suicides are a sorrowful form of communication, but they're also trial runs for the final event."à à à à à Anyone who commits suicide actually does not want to die and reality, just wants a solution to end their problems orà pains. In this case Willy's problem was he thought he was soà well-liked by society, however what he wanted most was forà his sons to like him, and for his wife to not have to suffer his torment anymore.

Comparing poems Essay
In this essay I am going to compare the way the theme of racism is dealt with in the poems ââ¬ËHalf casteââ¬â¢ and ââ¬Ënothings changedââ¬â¢. I will analyse the poems and then compare them. The things I will be comparing are the similarities and differences, the layout and also the use of language. I will be looking at both of the authors Tatamkhula Africa (Nothings Changed) and John Agard (Half caste) intentions and then decide which one of the poems I think is most effective. I am going to begin with a comparison of the purposes of the two poems. Nothings changed is about a black man looking back at his childhood and realising that ââ¬Ënothings changedââ¬â¢, he is upset about this as although segregation is said to have gone, he feels as if it is the same as before. Half-caste is about a mixed race man who is asking for an explanation for why they are treated like half a person. He refuses to be called half-caste as he finds it offensive. In both of these poems, the writer is dealing with the issues of racism. The two writers are expressing their anger and want the readers to take notice of how they feel. The two writers both use repetition throughout the poem. Tatamkhula used the phrase ââ¬Ënothings changedââ¬â¢ as both the title and the ending of the poem, this emphasises the fact that his whole poem is based on the fact that he feels that nothing has changed in his life, mainly on the aspect of the way black people are treated. John repeats ââ¬Ëexplain yuslefââ¬â¢ a number of times throughout the poem, he says this because his main aim of the poem is for people to explain themselves. These both are examples of repetition used by the writers to emphasise on their point that they want to get out by writing their poem. The two writers have a completely different style of writing. In nothings changed the writer uses standard use of English as he is happy to write this way. On the other hand the writer of half caste writes the words in slang. Clearly he wants to show the reader that he is what he is and is not going to change for anyone.à Tatamkhula compares a black person like himself to an ââ¬Ëamiable weedââ¬â¢, he is doing this as he feels that both black people and amiable weeds are not cared for. Also he believes they are not wanted. He then later compares a white person to the opposite, a ââ¬Ëred roseââ¬â¢, this maybe because he thinks that a lot of care is taken into caring for a red rose and also the white people. Here Tatamkhula expresses himself through metaphors and he does so continuously throughout the poem. Johnââ¬â¢s use of language happens to be really strong. He shows straight away that he is extremely angry. An example of this is that he said could have said you can come back tomorrow and listen my other half of my story if you want, however instead he demands the reader ââ¬Ëyu must come back tomorrowââ¬â¢. The ââ¬Ëmustââ¬â¢ emphasises that the writer is serious.à Both of these writers use different type of writing to express the way they feel. Tatamkhula effectively uses metaphors to compare what he feels like and what other people are being treated as. Johnââ¬â¢s strong use of language makes his poem more effective as he is showing exactly how he feels in the first instant. Both writersââ¬â¢ intentions are similar. They both want the reader to think about and understand what they are going through. They want these problems of racism to stop. Tatamkhula writes about what he sees and feels. An example of this is when writes ââ¬ËI press my nose to the dear panesââ¬â¢. Here he is on the other side of the glass from were the white people are sitting. This shows that he is separated from the people. He expresses that although segregation has said to be gone, it is still there. He can see the white people through the glass, however the glass is like a border where he can not pass only because of his colour. John Agard throughout the poem is writing as if he is speaking to the reader. It seems as if he is having a conversation with the reader, ââ¬Ëexcuse meââ¬â¢, I believe that this makes it more interesting, and also encourages the reader to take it more seriously.à He often uses the term ââ¬Ëhalf-casteââ¬â¢ to outsmart people who use this term. Although he uses slang he shows that he is aware of the things going an around the world. He says ââ¬Ëyu mean when Picasso mix red an green is a half-caste canvasââ¬â¢. This is an example of him having good knowledge and yet outsmarting the term ââ¬Ëhalf-casteââ¬â¢. Here he is arguing that if Picassoââ¬â¢s paintings can be a mixture of red and green, why canââ¬â¢t he be a mixture of races without being treated as half of a person. Tatamkhula explains how they are treated differently with the example of their food. At the ââ¬Ëwhites only innââ¬â¢ there is ââ¬Ëcrushed iceââ¬â¢, ââ¬Ëlinen fallsââ¬â¢ these both show expense and luxury items. He then compares this with what he is used to which is ââ¬Ëbunny chowsââ¬â¢ and ââ¬Ëplastic table topsââ¬â¢ This clearly shows that this is not an expensive place, yet more shows it is a cheap place. He then adds further ââ¬ËWipe your fingers on your jeansââ¬â¢ this shows that he is used to doing this, and yet is proud of doing it. He is not ashamed to express the way he is living and feeling. Both writers express their anger continuously through out the poem. They obviously want things to change, and want to be treated equally as everyone else. They express there feelings in form of a poem which they want people to take notice of, and maybe if they are the ones who are causing or doing something to make them feel like this, they would want them to stop instantly.à In my opinion I strongly believe that ââ¬ËNothings changedââ¬â¢ is far more effective. I think this because it expresses more how he feels and what he is going through. Although ââ¬ËHalf-Casteââ¬â¢ also expresses the writers feelings it is not as effective. This may be because Tatumkhula uses many examples of what he feels like and how he is treated differently.

Communicators of the Sea Essay
Dolphins are common creatures at rivers and seas. Majority of small toothed whales are dolphins. Dolphins are large sea animals making it part of the cetaceans, where whales and porpoises belong (Stoops, 1996). Dolphins belong to family Plantanistidae and Delphinidae, respectively. Often, people used dolphins and porpoises interchangeably denoting same species but porpoises in particuclar and dolphins are different species. Porpoises belong to family Phocaenidae; it has a rounded snout and chisel-liked teeth. While dolphins are under family Plantanistidae and Delphinidae, instead of a rounded snout, dolphins have beak like snout and sharp, conical teeth (http://www. dolphinlovers. com/facts. php) Fig. 1 Comparison between the snout of a porpoise and a dolphin Dolphins are outgoing creatures; often they are mingling in a group with two to fifteen animal members or more. Most of their communities are dominated by females, its offspring, sisters and other females. Subadult male dolphins will leave these female-dominated communities to start a group of ââ¬Å"bachelorâ⬠dolphins; if these dolphins become sexually mature, they can move in the female groups for copulation. These mammals are very playful. They are often spotted riding the bow wave or stern wake of boats and ââ¬Å"surfingâ⬠on waves. Chasing and tossing things to one another is one of their favorite plays. If seen jumping or breaching, it indicates enthusiasm for these creatures. Play is important for dolphins for learning and as well as to practice their skills necessary for their lifeââ¬â¢s survival (Geocities. com, 2006). Communication among marine animals, dolphins in particular are extensive and complex. The current paper focuses on these creaturesââ¬â¢ characteristics, particularly their capability to engage in echolocation. Dolphins can see their environment like that of an X-ray machine and thereby transmitting this x-ray like images to other dolphins. If sight is very crucial for land animals, dolphins use a sound ââ¬Å"seeingâ⬠system called echolocation. Echolocation is a sensory sonar system used by dolphins for communication purposes and for locating things in their environment. Through the sound waves released and listened to ââ¬â size, shape distance speed direction and internal structure of an object is determined. This sound seeing system provides information such as water depth and the position of food and rocks making it effortless for them to catch their prey. (http://www. botany. uwc. ac. za/Envfacts/facts/dolphins. htm, 2007). Scope The paper begins with an introduction about the dolphin, and their general characteristics as sea creatures. This is followed by a discussion of their general physiology, including their skin, fin, swimming speed, breathing, and body temperature. The dolphin family is then discussed, with its 33 species ââ¬â with 5 river species and 6 porpoise species. Of these, the most popular is said to be the bottlenose dolphin which are found in theme parks and are featured in television programs. The next focus would be on the dolphinââ¬â¢s brainpower, speficically in their capacity to make tunes among themselves with a wide range of sounds. Their distinctive communication patterns are likewise expounded on. The paper concludes with a call for concern and protection from humans, who are supposed to be stewards of these creatures. Overview With regards to its general physiology, dolphins have rubbery skin. They are classified as mammals and have the capacity of maintaining high body temperature. They can hold their breath for several minutes making it easy for them to have rapid and deep dives of more then 300 m (1,000 ft). To date, there are more than 33 different species of dolphins, over 5 different species of river dolphins and more than 6 different species of porpoises. Though there are many species of dolphins, the most popular are bottlenose dolphins which are frequently featured in television and theme parks. Perhaps their greatest strength is their ability to communicate with one another or to echolocate. This is the counterpart of language among humans. Dolphins create whistles and sounds signifying an action for which another dolphin can understand, it can signal danger for their kind hence they should be alert or a prey is near at hand thus, everybody must prepare; depending on the whistle produced. They can make signature whistles that carry distinct information. Considering the cognitive abilities of bottlenose dolphins, their vocal learning and copying skills, and their fissionââ¬âfusion social structure, their communication process can be further studied to provide evidences about their ââ¬Å"dolphin messages and echoes. â⬠Humans have the responsibility of taking care of these creatures, acting as their stewards to prevent them from extinction. General Physiology of a Dolphin A dolphinââ¬â¢s body is smooth having a rubbery-feel of its hairless skin when touched. The skeletal remnants of five digits in the front appendage form the flippers mainly acting as its balancer during its swim. The rear appendages are almost absent because the small pelvic bones are deep-rooted in the connective tissue at the base of the tail (Dolphin Lovers. com, 2006). The subcutaneous dermal tissue of the dolphin forms its immovable dorsal fin; its tail fin is also dermal in its origin. Its movement is similar with the whales wherein the major force comes from its vertical oscillations of the tail and flukes making it capable to swim at a speed of 37-40 km/h, and in some events, its swimming speed reaches up to 48 km/h. Dolphins seem restless in traveling the rivers but in reality, it rides the bow wave by making use of the shipââ¬â¢s trust (Stoops, 1996) Dolphins are mammals, hence breathing and maintaining high body temperature is vital. Dolphins maintain its internal temperature at 36. 5 deg to 37. 2 deg C (97. 9 deg to 99 deg F), with its thick layer of dense fat (blubber) under the skin. At the top of its head, a single nostril or blowhole is placed where it acts as its lungs. Dolphins breathe air at the surface every two minutes consisting of brief unpredictable exhalation followed by a longer inhalation. Dolphins are capable to hold their breath for several minutes making it easy for them to have rapid and deep dives of more then 300 m (1,000 ft) (Dolphin Lovers. com, 2006). Their swimming capabilities attribute to its powerful tail and the special function of its skin. Due to their streamlined body contour enabling them to have rapid movements and deep dives in the sea like most marine animals. Fig. 2 General physiology of a dolphin The Dolphin Family There are more than 33 different species of dolphins, over 5 different species of river dolphins and more than 6 different species of porpoises (Geocities. com, 2006). Fig. 3 Some Species of the Dolphin Family Though there are many species mentioned, bottlenose dolphins (Tursiops truncatus) are the most familiar species. It gained popularity because it has been a mainstay of TV programs. Also, people have the chance to meet and greet bottle nose dolphins at ocean-theme parks. The biggest dolphin specie is the one seen in the movie ââ¬Å"Free Willlyâ⬠; Orca (Orcinus orca) or the killer whale where the males can grow up to 9. 6 meters http://www. dolphinear. com/data/dolphin_species. htm Fig. 4. Picture of Orca and the Bottlenose Dolphin Dolphinââ¬â¢s Brainpower Greco and Gini (2005) say that dolphins are capable of making tunes among themselves with a wide range of sounds. Dolphins show evidence that their intelligence is greater than that of dogs. Dolphins learn easily and execute complicated tasks, continuous communications with one another, and their ability to mimic the sounds of human language if they are given ample time to be trained. Toothed whales have exceptionally large brains including the famously bright dolphins that have capabilities previously only attributed to humans and apes. Cetaceans (dolphins, whales and porpoises) and its ancestors acquired changes specifically in their brain through evolution. One of the reliable evidence to support this claim is by measuring the level of encephalization of a species or a taxonomic group. EQ is the measure of observed brain size relative to expected brain size derived from a regression of brain weight on body weight for a sample of species. EQ measures how much larger or smaller a speciesââ¬â¢ total brain size is from what is expected based on brain-body allometry (Greco et. al, 2003). Dolphins and humans share many common attributes. Both creatures are mammals wherein the young are born alive and not hatched from eggs. Air is important for both organisms since it sustains their breathing; the only difference is that dolphins must come up to the surface to breathe in its blowhole on the top of its head and when it dives, the blowhole closes unlike humans that continuously breathe air in its respiratory system. Wang (1995) asserts that aside from being mammals, communication is one the major attributes keeping these two organisms at par with one another. Humans are capable of language and speeches denoting an idea or message for a particular person while dolphins create whistles and sounds signifying an action for which another dolphin can understand, it can signal danger for their kind hence they should be alert or a prey is near at hand thus, everybody must prepare; depending on the whistle produced. Fig. 5 Illustration of the brain size of (a) archaeocete, Cetaceanââ¬â¢s ancestor (b) dolphin Distinctive Communication of Dolphins The capabilities of different organisms are astounding particularly in identifying objects from a far. The association between object characteristics such as visual shape, and sensory characteristics like retinal projection, is unclear. The processes on how these characteristics work hand-in-hand remains imprecise. Dolphins communicate by making two types of sounds: vocalizations and echolocation are the two sounds produced by dolphins for communication. Vocalizations are the squeaking sounds from the blowhole that is often heard by humans which is used by dolphins to communicate. Echolocation also called sonar, is a distinctive ability of dolphins to locate and discern objects down under (Janik, 2000). A dolphin releases a particular sound and listens for the echo allowing dolphins to travel under dark waters without bumping or hitting into anything. As much as 1,200 clicks/ sound can be produced in a second and can be transmitted in advance These clicks are from the rounded forehead of the dolphin, melon; along with its lower jaw filled with jelly-like substances for sound waves amplification. When a dolphin swims, the head is moved back and forth to skim through its surroundings, while the echoes are send out to bounce off objects aiming at the lower jawbone, returning sound waves to the inner ear, and this whole process occur rapidly, similarly to how fast a human brain decodes if the individual accidentally touches a hot object. The pitch of the returning echo and the time it takes to get there is important so the dolphin can determine the shape, size, speed, texture, and density of the object; even inside of an object, almost like an X-ray (McCowan, 2001). Echolocation is not solely for communicative processes; it also serves the purpose of locating preys, other dolphins, predators, a lost baby or a sick dolphin. Through echolocation, it allows dolphin to explore its water world wherein sight is of little use. Also, echolocation entails fast analysis of the sound being heard as to what message is conveyed by the dolphin who send the sound (http://www. dolphins-and-more. com/dolphins-echolocation. html) If a dolphin makes a sound, the sound bounces off into objects and creatures then it bounces back in the dolphinââ¬â¢s direction who is going to receive the sound and the information given by it when its sonar receives it. The dolphinââ¬â¢s brain comprehends the message obtained, hence the dolphin will respond accordingly to the message. Echolocation provides vibrations, their frequency, the level of energy, the distance and if the object is moving or not is very important. With these factors interacting, it creates varied ââ¬Å"dolphin messagesâ⬠(Tyack, 2000). Echolocating dolphins serve as models for object recognition sonar systems. The association between echo characteristics and object characteristics was given emphasis. A dolphin may keep ââ¬Ësound templatesââ¬â¢ in its brain and be able to recognize whole objects through listening for a particular sound. A dolphinââ¬â¢s brain may contain algorithms, resulting through natural endowments or experience or both, allowing it to identify object characteristics based on sounds (Wells et. al, 1987). Bottlenose dolphins are capabe of producing low frequency sounds ranging between 0. 25 to 150 kHz. Higher frequencies range make up echolocation; low frequencies sounds which is produced often are for social interaction, these low frequency signals can travel greater distance compared to that of higher as the signals travel much further distances. These frequency ranges are correlated with the amplitude obtained from studies of dolphins (Hoelzel, 2002). Click sounds are usually 40-70 microseconds, though short, these clicks are loud reaching around 220 decibels. Click trains are the sound sproduced by dolphins. It is consist of hundred or throusand of clicks per second which are high in frequency. High frequencies donââ¬â¢t travel as far as low frequencies, these high frequencies with very short wavelengths permit dolphins to echolocate on small objects and scrutinize the detail of an object. High frquency and the fine details of an objetc are directly proportional as such the higher frequecy produced, it would allow the dolphins to further examine the object at hand; also, it allows them to track their prey faster(www. dolphinpod. com). The localizing system ability of the dolphin Tursiops truncatus in discerning the characteristics of an object moving in radial motion was studied. The thresholds of the animalsââ¬â¢ threshold sensitivity at its target were given focus. The speed and acceleration were measured respectively (2. 6 cm/sec) (0. 6 cm/sec2). For a target moving at a constant speed, dolphins used probe signals made of two impulses. If targets are said to be accelerating, impulses composed of three signals are used. These methods are proven effective for technical methods concerning hydrolocation and radiolocation. hydrolocation and radiolocation (Zhukovski et. al. , 2004). The dolphinââ¬â¢s wave production and sound is inversely proportional; for every wave production, the sound decreases by only 4 à µ sec/decibel (dB). Low-frequency clicks (6-kHz peak power) are equivalent with three times increase far-reaching 12 à µ sec/dB. The dolphin brainstem is capable of tracking individual click/ 6oo seconds. The latency and amplitude are inversely proportional (as latency is increasing, amplitude decreases) with increasing click rates. This proportionality may vary depending on the wave production of dolphins. The dolphinââ¬â¢s brain is capable of processing short frequent clicks. The wave production in correlation with latency and frequency as well as click production can further test the sonar signal processing of dolphins (Ridgway, 1981). The echolocation process ââ¬â sending out clicks and listening to the click echoes ââ¬â is what produces a kind of mental image of the object that a dolphin is investigating with clicks. We know that the changes in the structure of the click echoes are what a dolphin uses to form this mental image, although it is still an unsolved mystery exactly how they manage to accomplish it. This echolocation ââ¬Ëimageââ¬â¢ is unlikely to be something that a human being could imagine simply because people canââ¬â¢t echolocate. But, this ââ¬Å"mental imageâ⬠is currently the best analogy weââ¬â¢ve got. Scientists have learned from experiments with dolphin echolocation that their acoustic image is quite detailed, and allows a dolphin to do some pretty amazing things Real targets are used to study dolphin echolocation. Classifying the echo parameters is very difficult due to various factors affecting such as physical dimensions and the reflection characteristic of real targets. Dolphin echolocation sounds are transformed into artificial echoes, which are played back to the animal. The phantom echo system, a digital sound processing is used to make echo analysis easier. Echoes of several underwater targets were simulated to evaluate the quality of the method (Aubauer and Whitlow, 1998). In bats and technological sonars, the gain of the receiver is increased with time after the transmission of a signal to balance off for the lost acoustic circulation. The current understanding of dolphin echolocation reveals that automatic gain control is not a part of dolphinââ¬â¢s sonar system (Tyack, 2000). Field measurements of free-ranging echolocating dolphins were tested and the results showed that dolphins do have automatic gain control mechanism which is put into practice during transmission phase rather than the receiving phase of a sonar cycle. The amplitude of the dolphinsââ¬â¢ echolocation signals are highly range dependent; this amplitude increases as the target increases, R, in a 20 log(R) fashion to compensate for propagation loss. If a school of fishes, with plenty of sound distributors would be the echolocation target, the echoes from the school will be nearly constant with range as the dolphin closes in on it. This characteristic has similar effect as time-varying gain in bats and technological sonar when considered from a sonar system perspective (Wells et. al, 1987). Echolocation ââ¬â or biosonar is an auditory imaging system used by various species for navigation and for tracking their prey in their vicinity particularly that their eyesight is incapble of helping them. Emission of vocalizations by the echolocating animal are emitted, detecting the echoes of those sounds and uses them to produce three-dimensional information about the environment. Also, these sounds help dolphins to be aware of their environment, preparing for an enemy attack (www. dolphinpod. com). Toothed whales, small mammals such as rats and shrews uses echolocation. These organisms comprehend their environment via the interpretation of acoustic reflections. In other words, echolocation is not just an ordianry auditory scene analysis, itrequires specialized neural mechanisms and complex computations for the oragnism to be able to understand the message given by the sender and to intrepret it corretly by the receiver. The neural circuitry underlying echolocation allows for the perceptual organization of auditory information, which guides complex spatially-guided behaviours. (www. seaworld. org). Whistles, buzzes, qucks and pops are the sounds produced by dolphins associated with travelling, socializing and feeding. Specific sounds are produced for a specific behavior which is also associated with changed in season. Pops are signifies feeding; quacks are for socialization; buzzes are for travelling purposes. During summer, dolphins are busy socializing with other dolphins and travelling for food hunt while during fall, dolphins are preparing for migration (Jacobs et. al, 2003). Smolker and Pepper (1999) state that dolphins are eager to learn new vocalizations (whistles) throughout life. Over a 4 yr study period, three male bottlenose dolphins are subjected to form an alliance, to herd female dolphins. Among individuals, whistle sounds produce are varied. The distinctiveness of individual repertoires decreased, the sounds produced by the three bottlenose dolphins became indistinguishable, because some whistles were shared among each other. By the end of the study, the three bottlenose dolphins had a common whistling sound which was never heard before the alliance was started. The frequency modulation pattern of the signature whistles of each dolphin contains sufficient information for specificity but the information received is used by the receiver to identify individuals. Dolphins do not have individual voice features but the sound production is greatly affected by changing water pressure (Janik, 1999), make voice recognition underwater more complex than that in the air. Also, the pitch and the time travel of the whistle or the sonar produced is also affected. Animals identify each otherââ¬â¢s whistles individually rather than just purely differentiating them. Recognition means perceiving something to be similar with an idea or learning that is previously known. Bottlenose dolphins identify themselves with a signature whistle. However, scientists have found no evidence of a dolphin language. A mother dolphin may whistle to her calf almost continuously for several days after giving birth. This acoustic imprinting helps the calf learn to identify its mother (Caldwell, Caldwell, and Tyack, 1990). Discrimination can also be used but it does not need previous learning from comparison purposes. The animals differentiate stimuli among them because animals are biased for one class of stimuli. The biases are mainly family based on a preference for an underlying feature in the modulation pattern used by related individuals. The other explanation is that the animals recognize the preferred stimulus individually particularly if the stimuli was encountered before clarifying previous confusion around the role or even existence of signature whistles (Janik, 1999,Tyack, 2000 and McCowan, 2001). Dolphins ability to and identity information in synthetic signature whistles that had all voice information removed demonstrates that the contour carries such signature information and that this information is used by the receiver. Janik and Slater (1998) argued that the need for individual recognition and group cohesion are the two key factors for the evolution of vocal learning in dolphins. Vocal learning enhances interindividual variability of signature whistles while maintaining potential group, population, or species features in the signal. In signature whistle development, a baby dolphin tends to duplicate the whistle that it only heard rarely adding slight modifications ending up as its own signature whistle (Fripp, et. al, 2005). This process leads to individually distinctive signature whistles. Geographic variation in whistle parameters over longer distances can also be a factor, the whistles produced by the dolphins at Ganges River are far different from those whistle sounds produced by those at Amazon River, or modifications are already done making each whistle sound unique (Wang,1995). However, the largest dolphin species, the killer whale (Orcinus orca), uses group-specific dialects in its communication system (Ford, 1983). Although vocal learning has evolved in one particular context, it can be used for other purposes once it is established. For example, learning also allows duplication of signals in direct social interactions. Dolphins frequently imitate each otherââ¬â¢s whistles in the wild (Wells. et. al, 1987). These signature whistles carries identity information independent from voice features portray the possibility of using these as referential signals, either addressing individuals or referring to a group, similar to the use of names in humans. Given the cognitive abilities of bottlenose dolphins (Janik, 1999), their vocal learning and copying skills, and their fissionââ¬âfusion social structure, their communication process can be further studied to provide evidences about their ââ¬Å"dolphin messages and echoes. â⬠Personal Conclusion All creatures have their own way of communication to their fellow species. Communication and echolocation among dolphins needs further study and experimentation. The processes involved in both communication (whistles) and echolocation are already established but the different factors affecting it are yet to be known. Dolphins have their unique sound, when calling a buddy and same with a mother dolphin calling her young. A mother dolphin whistles to her calf almost continuously for several days after giving birth. This acoustic imprinting produced by the mother dolphin helps the calf learn to identify its mother. Dolphins regulate their sounds by shunting air throughout the air sacs beneath the blowhole. Tissue structures in this area slap together (much like a trumpet playerââ¬â¢s lips) to produce the clicks. These sounds often extend into the ultrasound region. The whistling sound and the echoes emitted aids dolphins in their survival. The problem lies if the whistling signal denotes individuality or whether it is just a modification of a whistling sound heard within the surroundings. Other factors such as geographical variation, pitch, waves and others can alter the sound produced. It is just so amazing that despite these factors which need to be further studied, the communication processes among dolphins continuously exist. The meaning of the message is not altered despite the mentioned factors. Also, hundred clicks (sounds) can be produced by dolphins within a second but they are able to produce the correct whistle for a specific event and thus the receiver dolphin reacts accordingly. Aside from the clicks produced, neural activity is still studied on how dolphins can accurately compute the frequency of the clicks emitted for them to understand the message. The whistling communication process among dolphins makes them unique among other sea creatures. Echolocation helps them to locate objects since vision would not be adequate in locating objects down under; also helping them to avoid bumping into other objects like seaweeds and corals. Whistles and echoes are the counterpart of speech and language for humans. Humansââ¬â¢ brains and that of dolphins are relatively of the same size. Neural activity frequency computation still remains unclear. Though many computations had been published, it still seems inadequate to explain the processes involved within the dolphinââ¬â¢s brain. Also, it is fascinating how these control the sound emitted. Despite the factors affecting their communication such as season, water depth, noise pollution, geographic variation their system of communication never failed. Whether it be on great depths of water, the receiver had been effective in sending his message to the receiver. Humans and dolphins are relatively similar but would that be enough to support the conclusion that organisms with bigger brain structure are capable of communicating with one another? Does it follow that complexity is proportional with brain size? Is it safe to assume that humans and dolphins are closely related? Dolphins in Danger Dolphins are indeed lovely sea creatures. It entertains us in its own ways. And often, meaningful association between humans and these sea creatures may develop just like in the movies we watch. It is just unfortunate that man harms these lovely creatures as we pollute and destroy their habitats to serve our own purpose. Human beings are the most complex life forms and we must take the responsibility of protecting these friendly sea creatures. Dying Dolphin and Porpoise References Aubauer, R. and Au, W. (1998).
