A class can acquire the other class members. Inherited members are available for a classs use as though they were defined in the same class. Inheritance occurs when one class is derived from another. The strength of inheritance is to reuse the existing class and modify the existing class to a new class. Reusing the existing code minimizes the re-occurrences of instructions in a program. This unit introduces you to the inheritance feature of OOP. Inheritance is the capability by which the objects of one class inherit the members of the objects in another class. Consider class1 and class2. Class1 is used to derive/create class2. We will write a custom essay sample on Oop Inheritance or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Class1 is called the base class and class2 is called the derived class. To understand inheritance, consider the following example. Figure 1:Example for Inheritance In the Figure 1, the class Automobile can be classified into Car class Bus class In the example, Automobile is the base class. Car and Bus are called derived classes and belong to the base class Automobile. They share common characteristics and functions. For example, Automobiles are self-propelled vehicles that can move on the wheels. They are differentiated in few of their characteristics like number of seats, fuel type etc. 2. 0 ADVANTAGES OF INHERITANCE The advantages of inheritance are: * It allows the reusability of the base class function in the derived classes * The code and data are brought together in a class. It eliminates the duplication of code and promoting reuse. * Each derived class will only have the variables it needs. * Each derived class implements methods they way it needs to. 3. 0 TYPES OF INHERITANCE Inheritance enables to define a new class from an existing one. The existing class is the super or base class. The classes that are derived from the existing one are derived or subclasses. The relationship between the base and derived classes is referred as derivation or inheritance hierarchy. There are five ways of deriving a class as shown in Figure 2. Inheritance Single Inheritance Multiple Inheritances Hierarchical Inheritance Multilevel Inheritance Hybrid Inheritance Figure 2: Types of Inheritance 3. 0. 1 Single Inheritance Single inheritance is the type of inheritance where a derived class inherits only from one base class. This is shown in Figure 3. base_class derived _class Figure 3: Representation for Single Inheritance Consider the example of an Automobile. The base class is Automobile while the derived class is Car. Car inherits certain characteristics and functions only from the base class Automobile as shown in Figure 4. Automobile Car Figure 4: Example for Single Inheritance 3. 0. 2 Multiple Inheritance Multiple inheritance is the type of inheritance where a derived class inherits from many base classes. Consider the example of a child. A child inherits certain characteristics and functions of his/her father and mother as shown in Figure 5. Mother| | Father| | | | Child Figure 5: Example for Multiple Inheritance 3. 0. 3 Hierarchical Inheritance Hierarchical inheritance is the type of inheritance where many derived classes inherit from a single base class. Consider the example of an account. The savings, fixed deposit and the current account inherits the characteristics like account number, date of deposition of money in the account etc. nd functions like calculating the interest accordingly. This is represented in Figure 6. Account Savings Account| | Current Account| | | | Fixed Deposit Account Figure 6: Example for Hierarchical Inheritance 3. 0. 4 Multilevel Inheritance Multilevel inheritance is the type of inheritance, where a derived class inherits the members from the main base class. This derived class, in turn, acts as the base class for another class. Consider the example of a child. A child inherits from his/her father. The father inherits from his grandfather. This representation is shown in Figure 7. Grandfather Father Child Figure 7: Example for Multilevel Inheritance 3. 0. 5 Hybrid Inheritance Hybrid inheritance is the type of inheritance where multiple derived classes inherit members from a single base class. These derived classes further act as base classes for a single derived class. Consider the example of Apple. Green Apple and Golden Apple belong to the class of Apple. Hybrid Apple is obtained by the combination of Green and Golden apple. This representation is shown in Figure 8. Apple Hybrid Apple Green Apple Golden Apple Apple Hybrid Apple Green Apple Golden Apple Figure 8: Example for Hybrid Inheritance 4. 0 CONCLUSION Types of Inheritance| Description| Single| One derived class inherits members fromone base class| Multiple| One derived class inherits members frommany base classes| Hierarchical| Many derived classes inherit membersfrom one base class| Multilevel| One derived class inherits the membersfrom the main base class.

Jfk Assassination Essays (1448 words) - Lee Harvey Oswald

Jfk Assassination Essays (1448 words) - Lee Harvey Oswald Jfk Assassination FCA: Matt Motta Organization- /30 4/3/00 Support- /40 Block H Documentation- /30 JFK Assassination John F Kennedy was shot down unlawfully in his prime. That is a pin that has been in the nations back since it happened back on November 22, 1963. A theory that has lead the race of who killed JFK was the Lone Gunman theory of Lee Harvey Oswald. Since this theory has been so inconclusive, other theories have appeared and are catching up to Lee Harvey Oswald. Some of these theories are just ridiculous but on the other hand ,some are very possible. The most plausible theory is that Lee Harvey Oswald shot John F Kennedy during his drive through Dallas, there is not enough evidence to convict Oswald, so other theories have come about. On November 22, 1963, President Kennedy took a trip to Dallas, Texas to mend some old news with the democrats and to gain votes for the upcoming 1964 election. In Dallas, JFK was greeted by over 200,000 spectators through the uptown and downtown Dallas area. A motorcade had driven them to the Dallas Trade Mart where JFK was to make a speech, later on that day. JFK, along with his wife Jackie, traveled with Texas Governor John Connally and his wife Nellie drove to Dallas Love Field, where they arrived at 11:37 A.M. The motorcade then took a right from Harwood St., onto Main Street, headed towards Dealey Plaza, a park built to celebrate the birthplace of Dallas. The car then made a right turn onto Houston Street. Nellie Connolly, at this point turned to President Kennedy , and said you cant say Dallas doesnt love you.(Moore NP) Then the gunshot fired that woke up the world. At 12:30 P.M., on November 22, 1963, shots rang out in Dealey Plaza. To some of the witnesses on the scene, the first sounded like a firecracker. (Kritzberg 63) President Kennedy had wounds on his back, his throat, and numerous shots to the head. Governor Connally suffered a wound in his back, his chest, two wounds in his right wrist, and a wound in his left thigh. Fortunately, these wounds were not fatal for the Governor. (Donnelly 116-120) A bystander named James Tague was wounded on his cheek by a bullet and/or concrete fragments caused by a missed shot. (Kritzberg 63) Witnesses at the scene heard anywhere from 2 shots to 7 shots. It was concluded these shots came out a rifle. The rifle was later found hidden behind some boxes as well as three empty cartridge cases in the same room as the suspected shooting, in the Texas School Book Depository Building. The police were later accused of planting the rifle and cartridge cases. President Kennedy was pronounced dead at 1 p.m., central standard time. (Donnelly 69) The most suspected shooter was Lee Harvey Oswald. Oswald belonged to the Marine Corp for most of his life. Oswald was trained in radar electronics, and had a background in security clearance. Oswald had experience with rifles, contacts in the CIA, possibly the Soviet Union and the KGB. The government claims that Oswald was just someone off the street who had a grudge against Kennedy. (Benson 190-193) Oswald was a communist, which would mean the Oswald believed that the president was no better than any other man. His beliefs made him an instant suspect for the CIA. (Benson 147) A major point in the discussion if Oswald did it or not is that the parade was running 6 minutes late. This means Oswald wouldnt have known, which he means he was waiting at the window for at least 6 minutes which he wasnt. Throughout the assassination Oswald was said to have been in the lunch room , however , no one could provide proof that they had seen him in the room where the shots were fired. Police swarmed the Texas School Book Depository Building believing the shots came from the third floor. On their way, they found Oswald sitting in the Lunch Room composed and quietly eating his lunch. (Kritzberg 60, 61, 69)Officer Baley was the police officer who entered the building after the shots were fired. When he did , he found Oswald in the Lunch Room. This created a problem in the timing element of the assassination. If Oswald were the shooter, then he would have needed to run four floors to the window where the shots were fired, then run back in 90 seconds to the lunch room. Oswalds arrest seems suspicious at this point because had he fired 4 shots and ran four floors as well

Politicians and Humpty Dumpty

Politicians and Humpty Dumpty Politicians and Humpty Dumpty Politicians and Humpty Dumpty By Maeve Maddox When I use a word, Humpty Dumpty said, in a rather scornful tone, it means just what I choose it to mean, neither more nor less. The question is, said Alice, whether you can make words mean so many different things. The question is, said Humpty Dumpty, which is to be master thats all. (Through the Looking-Glass Chapter Six) I was in Arkansas the year that then-governor Mike Huckabee refused to sign a tornado relief bill because he objected to the conventional term act of God: act of God uncontrollable natural force first recorded 1882. (Online Etymology Dictionary) On December 31, 2007. the Los Angeles Times reminded the nation of this incident in an article that has stirred up a lot of blog commentary. In order to mitigate fears that the Baptist presidential hopeful would permit his religious beliefs to interfere with decisions of state, Huckabee apologists have come to his defense. They argue that Huckabee merely wanted to change the terminology so that insurance companies would pay. According to a NY Times story dated March 21, 1997, however, Huckabee refused to sign the bill because doing so would violate his conscience: Mr. Huckabee said that signing the legislation would be violating my own conscience inasmuch as it described a destructive and deadly force as being an act of God. Mr. Huckabeesuggested that the phrase acts of God be changed to natural disasters. All language is metaphor. The word is not the thing. The map is not the territory.

PredatorPrey Relationships in West Virginia Essay

PredatorPrey Relationships in West Virginia - Essay Example Many believe the carrying capacity, the maximum number of animals the environment can support has been reached this can have devastating outcomes (Grafton 2008). There are major problems with deer populations in many states; however, in West Virginia populations can run as high as 75 deer per square mile (Williams 2005). In all cases, the root of the problem stems from a lack of natural predators and an ecological negative feedback loop that involves declines in forest health and composition. White tailed deer populations in excess of 20 per square mile are largely responsible for lack of woody and herbaceous regeneration (Grace 2008). Habitat impacts from such extensive deer overpopulation range from destruction of native understory, as deer are mostly browsers, eliminating low growing shrubs and herbaceous material to loss of small mammals and their predators. They are also responsible for dramatic changes in the hardwood diversity of eastern forests when they browse on immature hardwoods, killing them and thereby changing the fundamental structure of the canopy (Grace 2008). This affects every species in the system. The US Forest Service determined at more than 20 deer per square mile, there is a loss of many common bird species such as cerulean warblers, yellow-billed Cuckoos, indigo buntings, eastern peewees, and even robins disappear (Williams 2005). With the loss of these botanical species and associated birds, there is also a loss of small mammals due to lack of adequate cover and food resources (Broache 2005). Interestingly, it has been shown that silvicultural practices in managed hardwood forests of West Virginia have contributed to an initial increase of small mammal abundance diversity, usually until succession returns to the forest area (Kirkland 1975). This is thought to be due to an increase in consumption of seeds and seedlings, which in the long term has a deleterious impact on forest regeneration. In addition to anthropological restructuring of the forest's ecosystem, deer overpopulation has compounded the problem. Habitat alteration contributes to what still may be the root of the problem, which is the loss of the deer's natural predators from the system; bear, wolves and cougar that began in the 1700s. Numbers of the eastern timber wolf, black bear, and eastern cougar and all at historic lows since the area was first settled in the 1700s. Black bear in the state are estimated to be fewer than 8,000 individuals and both the wolf and cougar are listed on the Endangered Species list (Weaver 2007, USFWS 2008). Studies in Yellowstone have shown that large predators actually increase herd fitness by 30-40 percent when the herd has good quality habitat in which to bed, hide and feed upon (Brown 2006). Large predator prey relationships were studied over the long term at Michigan's Isle Royale National Park, where wolf and moose populations were shown to rise and fall in connected cycles (Milhill, 2008). The lack of predators in National Parks such as Yosemite and Zion has lead to large deer populations where stream bank erosion and loss of habitat for amphibians and butterflies have occurred (Milhill, 2008). With the lack of these large predators to help maintain deer populations, the dee r are beginning to overpopulate the landscape, which hurts not only the ecology of the

The Albany Congress Essay Example for Free

The Albany Congress Essay During the two Decades from 1754 to 1775, the American colonies moved from division to unity. The accomplishments of the Albany Congress, the Stamp Act Congress, and the First Continental Congress caused this change. The Albany Congress was held in 1754. It was a meeting of representatives from various colonies in response to the war between Britain and France. The main plan was to form a colonial defense and gain the support of the Iroquois Confederacy. They also debated an intercolonial government. Ben Franklin and Thomas Hutchinson were the authors of the Albany Plan. They proposed an elected assembly would plan for a common defense paid for by taxes levied by congress. Although the plan did not pass, because the colonies were not ready to share their powers to tax with each other, it did put the idea of a unified nation in the minds of the colonists. The Stamp Act Congress was held in New York City in1765. Delegates from 9 American Colonies gathered to respond to the Stamp Act Parliament passed. The Stamp Act taxed commercial or legal documents, licenses, newspapers, permits, pamphlets and even playing cards. It was not a heavy tax but if they let Parliament pass this tax, they would only have more in the future. No taxation without representation basically means the English colonies did not want to be taxed without their consent. The First Continental Congress met in 1774 in Philadelphia to protest Britains Intolerable Acts (Coercive Acts): 1. Boston Ports would be closed until compensation was met to the East India Tea Company for the Boston Tea Party. 2. The Colonial Charter was annulled and they replaced colonial officials with royal officials and they banned town meetings. 3. Royal Officers would not be tried in colonial courts. 4. They legalized quartering of troops in public buildings and private homes. 5. They established a government in Quebec and gave them the territory claimed by colonists North of the Ohio River. Twelve of the colonies were present at the meeting (not Georgia.) They urged the colonies to form militias. They formed the Continental Association to boycott British goods. They also voted to reconvene the following spring if Britain would not redress American grievances. After this meeting, the majority of the colonies were in unity.

Marketing, Advertising, Style and Art Essay -- Marketing Advertising A

Marketing, Advertising, Style and Art: Life Should be Lived, Not Painted Man-made objects produced for acquisition depend on the ability to carry an image of style. The consumer is persuaded that ownership will enable them to inherit this style transforming their lives into perfect, happy reflections of the people featured in advertisements. These objects can be applied to any aspect of life as a fast answer to the question of style. The media promotes and reflects the current mainstream culture's standards for life style, class and importance of appearance. The media uses images of thin, beautiful women in well kept stylish homes and links these images to other symbols of prestige, happiness, love and success for women. Repeated exposure to this ideal via the various media can lead to the internalisation of this ideal. It also renders these images achievable and real. By targeting advertisements at set demographic groups, the choice of how to split responsibility for domestic chores is taken away. Instead we are presented with a list of acceptable social rules that are different for each gender. An example would be Fairy washing up liquid, in the advertisements we always see a mother doing dishes, with her child somewhere near by. This is communicating a message that washing up is a women’s work and worse still a feminine thing to do, as if to say a man who washes up risks losing part of his masculinity. When considered it seems ridiculous that we would let the media keep such sexist themes alive but the sad fact is that the majority are so conditioned to this train of thought, in order to preserve our gender identities, we must conform. Objects therefore not only posses the power to add style to our lives but to delegat... ...lives it is just a case of applying the same recipe. For instance look at a new sofa in a shop window now forget its advertising style and price, refuse to listen to the cocky sales person and think. Look at it for what it is, an object, with one use and one use only to sit on. Obsession with possessions is everyone’s burden the key is in realising we are all involved in a universal scam. Instead of accepting things as they are presented, take them out of context and produce a new meaning. Once this new meaning has been regarded something of the original meaning is lost forever and in this way we can liberate ourselves. Using these ideas as a tool to reject the regimes that the media present, to re-write the language of style. Many people have used an expression as a defining point of their admiration for Marcel Duchamp’s ideals â€Å"life should be lived, not painted†.

African American and Their Rights Essay

Since slavery, African Americans have gone through a lot to reach their current state. In the early 20th century, African Americans faced discrimination, isolation, and were segregated according to their skin color. It started when Europeans brought the first Africans to America, and continued throughout the Civil War. The American government made some changes in policies. A variety of leaders shaped the successful struggle toward black equality in America (Bowles, 2011). Ever since slavery begun, African Americans have been determined to end segregation, discrimination, and isolation. Activists such as, Martin Luther King Jr. and Malcolm X, and others, joined together to put an end to segregation, discrimination, and isolation to attain civil rights and equality. Slavery had changed dramatically in the late 1600s. About this time the slave trade to American colonies also began increasing to meet the demand for cheap labor. Traders sold slaves to the Northern colonies, but English and other European immigrants satisfied the demand for labor there (Echerd, 2009). Slaves in America came from western and central Africa. African tribes sometimes enslaved those defeated in intertribal wars and sold their captives to European slave traders. The tribes raided villages to obtain slaves to trade for European goods. Slave traders had even offered the Africans guns and other goods for the slaves. Slaves lived a rough, hard life. Cheap labor was a huge part of their lives. They had to work from sunrise to sunset. The work consisted of clearing land, tended to fields of tobacco, rice, and vegetables. They also performed many other tasks that had helped make plantations almost completely self-sufficient. No slaves saw any money for their tasks that they had performed, but they did receive food, clothing, and shelter. The slaves had resided in small one-room huts, which had no windows and the floors were all dirt. Most slaves accepted their living condition, however, they knew no other way of life (Koehler, 2009). However, white Southerners regained control of state governments in the South during the late 1870s, however, and reversed most of the previous gains made by former slaves. For example: segregation. What is segregation? According to Webster’s Dictionary, to segregate is defined as to separate or set apart from others; isolate or to require, often with force, the separation of a specific racial, religious, or other group from the body of society. Segregation has been a part of our American heritage, almost from the moment slaves arrived on the shores of the New World (Bowles, 2011). In 17th century Virginia, the theocratic government feared that racial mixing between freed and enslaved blacks and white indentured servants would become a means to usurp government power. They passed laws in which the color line was clearly defined in any criminal punishments. By treating whites and blacks separately and unequally, these Virginian leaders set up a system of white supremacy that would become an essential component of American slavery. Separation and segregation was the order of the day, with African Americans being forced to ride in separate railroad cars, have their own hotels and courthouses, and even get water out of their own drinking fountains. Their children could not attend the same schools with the White children. To further push the color-line, they then added in segregation with the Jim Crow Laws. This is mainly because the Whites were considered to be superior, and hence were thought to deserve better schools with better facilities. African Americans on the other hand were considered inferior, and hence their children attended low-quality schools that lacked adequate facilities (Sitkoff & Franklin, 2008). The Northern States, which had grew and prospered during the war, believed the former slaves to be equal as any other person. The Southern States, still angry over the loss of the war and their firm belief in White superiority, took a different approach. They created and enforced what were known as the Black Codes. These were legislations passed in Southern states to control labor, migration and other activities of the freed slaves. Black Codes allowed legal marriage, property ownership and limited access to the court systems. It prohibited them from testifying against whites, serving on juries or militias, voting and publicly expressing any form of legal concerns ( www. history. com). Any former slave that did not sign yearly labor contract with the plantation owners could be arrested and hired out. The Black codes in short allowed for the continued and legal discrimination against the former slaves (www. history. com). Congress quickly responded to these laws in 1866 and seized the initiative in remaking the south. Republicans wanted to ensure that with the remaking the south, freed blacks were made viable members of society. But the strong southern legislatures finally gave in; in 1868 they repealed most of the laws that discriminated against blacks. Things were starting to look up. But by 1877 Democratic parties regained their power of the south and ended reconstruction. In 1882, southern states passed Jim Crow laws that enforced strict segregation between blacks and whites and limited African-American civil rights. This was devastating to the blacks. After all the strides they made were reversed. From holding political offices, the right to vote, and participating as equal members of society was changed. The south gradually reinstated the racially discriminatory laws. The two main goals they wanted these laws to achieve: disenfranchisement and segregation. To take away the power that the blacks had gained, the Democratic Party began to stop Blacks from voting. There were many ways to stop blacks from voting. Some of these things were poll tax, which were fees were charged at voting booths and were expensive for most blacks, and the literacy test. Since teaching blacks were illegal, most adult blacks were former slaves and illiterate. And the other goal, segregation, causes the democrats to create laws that segregated the schools and public facilities. The Northern States, which had grew and prospered during the war, believed the former slaves to be equal as any other person. The Southern States, still angry over the loss of the war and their firm belief in White superiority, took a different approach. They created and enforced what were known as the Black Codes. These were legislations passed in Southern states to control labor, migration and other activities of the freed slaves. Black Codes allowed legal marriage, property ownership and limited access to the court systems. It prohibited them from testifying against whites, serving on juries or militias, voting and publicly expressing any form of legal concerns. Any former slave that did not sign yearly labor contract with the plantation owners could be arrested and hired out. The Black codes in short allowed for the continued and legal discrimination against the former slaves. Just like some African Americans activists fought this segregation, some Whites had some groups of their own to carry the segregation on and on. The Ku Klux Klan was one of them. The Ku Klux Klan, Knights of White Camellia, and other terrorists murdered thousands of blacks and some whites to prevent them from voting and participating in public life. The KKK was founded in 1865 to 1866. They directed their violence towards black landowners, politicians, and community leaders. They also did this to people who supported Republicans or racial equalities (Anti-Defamation League, 2012). After the abolishment of slavery in the U. S. the KKK formed. They hated blacks and would commit crimes against them. Murders, hangings, and lynches are just some of the crimes against the blacks (www. kkk. bz, n. d. ). The Ku Klux Klan claims to be just defending their people like other races do. What is a lynching? Lynching is a form of punishment with no legal permission. Most times lynching occurred against African Americans by hanging them. This was very popular during the Gilded Age after the American Civil War when African Americans were freed from slavery. Many White men would use lynching against Black men for being in a mixed relationship with a White woman. However, because lynching had no legal basis, it was thought to have been a tool that was used against freed slaves that had achieved financial stability and authority in order to remain a White-dominated nation. Lynching was most likely performed by White Supremacy groups like the KKK. Lynching was done by hanging or shooting, or both. However, many were of a more hideous nature. Burning at the stake, maiming, dismemberment, castration, and other brutal methods of physical torture are all part of a lynching. Lynching therefore was a cruel combination of racism and sadism, which was utilized primarily to sustain the caste system in the South. Many white people believed that Negroes could only be controlled by fear. To them, lynching was seen as the most effective means of control. Defending your people is one thing, but to torture another human being is inhuman. The KKK has several stories out there today on how they treated the blacks, whether they did anything wrong or not. For instance, a Louisiana woman is in critical condition after she was set on fire, resulting in burns on roughly 60 percent of her body, and her car appears to have had racial slurs written on it at the time of her attack (Mach, n. d. ). They had even gone as far as church bombings. The KKK launched a bomb into a church during a Sunday service, which left four innocent teenage girls dead. The men responsible hid behind the cloak of secrecy, intimidation and the white robes of the oldest terrorist organization in the world, the Ku Klux Klan (Gado, n. d. ). Therefore, until the Civil Rights Act of 1964, racial discrimination is an issue that was not seriously tackled. The act was a successful result of most wide-ranging civil rights legislation and Civil Rights Movements for close to a century (Finkelman, 2009). The act declared discrimination on the basis of color, race, ethnicity, religion, and many other aspects as unconstitutional. During the critical years from 1954 to 1963, a variety of leaders with different backgrounds, such as lawyers from the NAACP, women sitting on buses, ministers from southern black churches, militants from black power organizations, and youth from colleges had shaped the successful struggle toward black equality in America (Bowles, 2011). In 1896, the Supreme Court’s Plessy v. Ferguson decision established that â€Å"separate but equal† facilities for whites and blacks were allowable under the U. S. Constitution. Local governmental officials could designate separate public facilities like drinking fountains, restrooms, and schools. Even courthouses often had separate Bibles according to the defendant’s race. The problem was that separate usually meant unequal, and segregation subverted the freedom of every African American (Sundquist, 1993). Now, it is time for the African- Americans to fight back. The incident that made them want to make a difference was the Rosa Park bus ride. After a long day of work on December 1, 1955, Parks, feet hurt, looked forward to sitting on the bus for her ride home. At the time, there was a city ordinance stating that African Americans had to give up their seats on a train or bus if a white man asked for them. When a white man approached Parks and told her that he wanted her seat, she simply said no. Although she acted as a private citizen, her response was as an informed, committed member of the NAACP movement. The bus driver had asked Parks to move. When she did not, the bus driver said, â€Å"Look, woman, I told you I wanted the seat. Are you going to stand up? † When Parks again said no, the driver threatened, â€Å"If you don’t stand up, I’m going to have you arrested. † She gave no reply but at the next stop, Rosa was arrested (Garrow, 2004). A pastor known as Martin Luther King Jr., organized a boycott, the Montgomery bus boycott. King Jr. took this to a higher level and maintained and organized the Southern Christian Leadership Conference (SCLC), which coordinated similar bus boycotts in other cities. Shortly after the boycott, King had found a bomb on his porch. King went to Birmingham, Alabama, where he continued his nonviolent protests and marches. However, the police authorized force to disband King’s followers by using electric cattle prods, tear gas, and fire hoses (Bowles, 2011). King was arrested with the others, but upon his release from jail he went to Washington, D. C., where he and demonstrators met at the National Mall and addressed them with his famous â€Å"We Shall Overcome† speech on August 23, 1963. King’s words at the capital that day were a defining moment of the Civil Rights movement. Other demonstrations and civil disobedience campaigns sought to increase African-American voter registration and win better jobs. Malcolm X actively promoted the Black Muslim cause. Even after speaking about non-violence and wanting peace, Martin Luther King Jr. was assassinated. The civil rights movement dramatically increased participation of African- American voters in both the South and the North today. By the mid-70s some 4000 African-Americans have been elected to political office at all levels of government. Qualified African-Americans now have a wider range of opportunities than ever before. Whether you are White or African-American, each group has faced its own peculiar challenges on its approach to democracy (Rappaport, 2001). This racism is wrong and unconstitutional. The 13th Amendment is ratified, abolishing slavery, which some people still went against it. The 14th Amendment granted citizenship to the former slaves and forbade states from denying any person life, liberty, or property without due process of the law. The 14th Amendment also guaranteed equal protection of the law for all citizens. The 15th Amendment barred states from denying citizens the right to vote based on race, color, or previous servitude (Hertz, 2009). In a perfect world, everyone would be equal. The color of one’s skin, religious beliefs or sexual preference would mean nothing. We would accept everyone for whom and what they are. We would rejoice in the differences between each other instead of belittling, hating and discriminating against those differences. We don’t however live in a perfect world. We live in a world filled with distrust and hate. If we don’t know or understand it in our society, then it is wrong. It will be discriminated against in one form or another. We as a country have made major strides in overcoming racism, however we still have far to go. In conclusion, African Americans faced isolation, discrimination, and segregation during the post-construction period. Racial discrimination was also prevalent in the military where back soldiers were considered inferior to white soldiers and hence poorly trained and equipped. The issue of racial discrimination, isolation and segregation was not seriously tackled until the Civil Rights Act of 1964 was enacted. Civil rights activists such as Malcolm X and Martin Luther King Jr. organized the famous 1963 protest in Washington that eventually forced President John Kennedy to pass the Act. It is therefore, clear that the journey to end isolation, discrimination, and segregation to attain equality and civil rights has been hard but worthwhile. ? References Bowles, M. (2011).

Research Paper on Abortion

The ethics of abortion is one of the most controversial topic that has been continually argued over years and probably many years to come. The main controversy is the question of legalization of abortion, which ties into ethical issues, emotions, and political issues or laws. Before I discuss the many sides to abortion, it is critical to define the term. The Webster’s Dictionary defines abortion as the termination of a pregnancy after, accompanied by, resulting in, or closely followed by the death of the fetus. Despite the liberal attitudes toward abortion, it still remains an important political issue. Even in societies where abortion has been legalized, many actions are being raised by the anti-abortionists. These anti-abortionists believe in â€Å"pro-life† and their religious perspectives are responsible in their arguments against abortion. They believe that â€Å"it is equally as heinous intentionally to kill a human being in existence at fertilization, as to kill a larger pre-born child. † On the other hand, there are reasons for legalization of abortion. Most people agree with the concept of reproductive freedom—the fundamental right of every individual to decide freely and responsibly when and whether to have a child. Human life is defined as â€Å"any living entity that has DNA from the species homo sapiens. This includes an ovum, spermatozoon, zygote, embryo, fetus, newborn. It also includes an infant, child, adult, elder. It also includes a breast cancer cell and a hair follicle and a skin scraping. Some forms of human life have little or no value; others are the most valuable and precious form of life in the known universe†. Because an unborn fetus is considered to have a human life, abortion should not be legalized. It is a definitely a crime to kill a living and breathing fetus even though the embryo may not take the form of a human structure. If abortion is permitted, the dignity of human will be destroyed. In the medical field, the doctors prescribe the baby before 15 days after conception as dividing cells. But after this short period, abortion is prohibited from the principal of identifying. This is because the fertilization process contains many cell divisions by zygote progressing into a human being. Many people assert the right that women do not have a baby because they have the right to choose. But it is neglecting the right of the baby who has his or her own life. Just because an unborn fetus is not capable to express his or her feelings, is it morally right to end its life? Considering moral issues, abortion is definitely equally termed a murder. However, I do understand the other point of view for legalizing abortion. The exception to abortion is considered when the mother bearing the child has illnesses or diseases that can be transmitted to the baby genetically. Also, financial issues are often being raised by the parents whom are not able to support another family in the house. In this case, abortion may be permitted because it is rather better to not be alive than be living under such poor conditions. Furthermore, abortion is considered as a rightful act when the women get pregnant from rape. Some people may generally think that a crippled person is pessimistic about the world. But in fact, they thank their parents who gave life to them. The life as a handicapped person could be better than not experiencing life at all. If it’s not by the force of other one, people must take the responsibility for their behavior. Every action you make comes in consequences and therefore, it is important to choose birth controls if pregnancy is not wanted. If the reason that causing abortion is merely a problem of foster, it is never permitted. We must keep in mind that life is most precious thing in the world. It is estimated that the number of aborted babies is almost 4000 in a month. Vast majority of abortions are done for convenience, by women who simply want to terminate an unwanted pregnancy. But abortion is a murder. So, now is the time for us to think about the abortion again and to search for the best solution. In any circumstances, the life must be admired.

Hypothesis testing homework solutions Essays - Summary Statistics Hypothesis testing homework solutions Setting up and interpreting results of a hypothesis test ACT-1. Practice with p-values Use the density tool to practice finding p-values. I. Set the mean to 35, the standard deviation to 12.5, and the sample size to 100. What is the probability of finding a value: a. less than 33 .055 b. greater than 37.1 .039 c. less than 32.8 or greater than 36.9 .039+.065=.104 II. Change the sample size to 250. Now that the sample size is greater, find the following probabilities and compare them with those found in the first question: a. less than 33 .006 b. greater than 37.1 .004 c. less than 32.8 or greater than 36.9 .003+.008=.011 Larger samples taken from the same population have a much smaller chance to have a mean value far from the population mean. Increasing the sample size by a factor of 2.5 decreased the likelihood of these rare events by a factor of 10. III. Keeping the sample size at 250 and the mean at 35, try changing the standard deviation to 11 (a difference of only 1.5 from the previous standard deviation) and compare these results with the results you obtained in the second question. a. less than 33 .034 b. greater than 37.1 .029 c. less than 32.8 or greater than 36.9 .023+.042=.065 A relatively small, about 10% decrease in the standard deviation had a huge effect increasing (by a factor of 6) the chances for certain sample mean values to come up that are far form the population mean.. IV. Set the mean to 34, the standard deviation to 12.5, and the sample size to 100. Find the following probabilities and compare them with the ones you found in the first question. a. less than 33 .21 b. greater than 37.1 .007 c. less than 32.8 or greater than 36.9 .167+.01=.177 33 is much closer (almost 1.25 closer which would be a full standard deviation closer) to the mean now so chances for a sample mean to be 33 increased dramatically. On the other and 37.1is a full standard deviation further than where it was when the mean was 35. therefore fewer samples show this value. In part c) the lower value got closer the higher value mover further form the mean so it evens out to about the same chance overall as in the corresponding part in I. Write a brief summary of what you observed when certain values were changed. MRA-1. Population Mean Hypotheses Each of the following paragraphs calls for a statistical test about a population mean m. State the null hypothesis H0 and the alternative hypothesis Ha in each case. (a)The diameter of a spindle in a small motor is supposed to be 5 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of motors to determine whether the mean diameter has moved away from the target. H0: =5 Ha: 5 (b)Census Bureau data show that the mean household income in the area served by a shopping mall is $42,500 per year. A market research firm questions shoppers at the mall. The researchers suspect the mean household income of mall shoppers is higher than that of the general population. H0: =42,500$ Ha: >42,500$ The examinations in a large accounting class are scaled after grading so that the mean score is 50. The professor thinks that one teaching assistant is a poor teacher and suspects that his students have a lower mean score than the class as a whole. The TA's students this semester can be considered a sample from the population of all students in the course, so the professor compares their mean score with 50. H0: =50 Ha: 50 MRA-4. Explaining Ethnocentrism A social psychologist reports that in our sample, "ethnocentrism was significantly higher (p= 0.05) among church attenders than among nonattenders." Explain what this means in language understandable to someone who knows no statistics. Do not use the word "significance" in your answer. Researchers found that the percentage of ethnocentrics was higher among church attenders compared with the same percentage for non-attenders. In fact the evidence for that was so extreme that if there was no difference between the percentage of ethnocentrics between attenders and non-attenders we would see

Censorship Gone Too Far

This review has passed seven cited quotes regardless of whether you entered the music store or not and you are seeing parent consultation stickers in most of today's popular music. Or, the TV viewer rating is displayed in the upper left corner of your favorite show. What is your favorite video game rating? I believe that you have, but you truly know the influence of these so-called harmless stickers and images on the world of entertainment and your freedom of expression. Recently, in the United States I advertised family values Music review by students at the University of Maryland has gone far. Recently, society as a whole has been influenced by increasingly intense controversy over music censorship. The censorship system is defined as the supervision and management of information and dissemination in society. Many people think that reviewing music is only hiding the truth of American people. This is obviously a biased problem involving the music industry and the people with which i t interacts. Because everyone has their own perspective, censorship is subject to increasingly hot discussion and discussion. The censorship system is unconstitutional as it restricts people's freedom of speech. If legislators can limit this right, what rights do they restrict next? It is a direct infringement of the rights given to us in the first amendment and further reviews should not allow for review if the government limits one right! The censorship system is a controversial subject, and many people think that there are too many censorship systems, but many people think censorship system is far from sufficient. Most people agree that censorship is the management of information and ideas communicated in society. Books can be banned for four reasons: politics, sex, society, religion. - Throughout history, books had a major impact on the society they write. Many of the most important classics in history were challenged or even banned by people of those days. Great novels like Mar k Twain's Adventures of The Huckleberry Finn and Nathaniel Hawthorne's Red Letter have been challenging for years.

Velocity 2 - Part II - Assignment Example In my opinion, this creates more waste. The reason this is said is that such employees who are neglected rather refuse to add any value to the organization. It is therefore important to identify lack of employee utilization as a major bottleneck within the organization, which is worth addressing for the collective success of the organization (King, 2011). The points you raised are very important and useful for any organization that wants to clearly identify why it is not improving. This is because conflict among management can be a major hindrance that will retard the growth of organizations. As an insight to the situation, I believe that most organizations come to face this bottleneck when there is lack of clear consensus as to who should take leadership affair and manage the organization. Most of the time, everyone wants to be a leader of their own, creating so much conflict of ideas (King, 2011). There is however a way out to dealing with this situation. Instead of everyone seeing themselves as bosses, the company can employ the use of shared responsibility, where specific roles are defined to each person. After this, each person must be given clear demarcations as to where their authority ends. Then more importantly, the roles of the leaders must be joined together with the collective goal of the organization so as to avoid the w aste of leadership resources (Jacob,
