Steryotypes Of Teenagers

I am writing to inform you about how I feel when I see certain articles that have been published in your newspaper. Most of these articles are about teenagers with a lot of negative coverage. I hope through this letter that you will understand what so many teenagers feel when reading the negative articles that YOU publish. Hopefully, after this letter you won’t ever stereotype anyone without full information about them again. It was just last week that I was reading a copy of ‘The Sun’ when my eyes focussed on this one article, it was titled ‘Jeremy’s ‘Happy Slap’ Ordeal’.My eye then alighted on Jeremy Clarkson’s face, (the guy from Top Gear) and that I think just spurred me on to read more. I didn’t really know what to expect but honestly I had no idea this was about teenagers. Whilst reading this article I realized something was wrong. Usually when you have an article like this in the newspapers there’s alway s two points of view. Normally the two parties or persons involved have a say, but this particular article shows extreme bias.We simply hear Jeremy’s point of view and leave the teenagers opinions unheard. Personally I think this is very unfair, when journalists do things like this, it’s not right; it’s actually very sly and manipulative. You instantly portray Clarkson as ‘our man†¦ the victim’ and the others as ‘a gang of teenage thugs’. How are reader’s going to have a balanced view of the situation, when this is how you set the article up? There is one quote in the article about police which I am angry about, which is â€Å"the police?Oh come on they are too busy filling in health and safety forms and processing speeding fines†. This quote irritates me dramatically because frankly it’s not true. The, I see them police are not too busy with speeding fines or health and safety forms. I always see police when I go out dealing with young drunk men or people brawling in the street. This tells me that Jeremy was wrong about the police. Jeremy Clarkson has obviously been brainwashed by the media.He’s just making assumptions about stuff, like most famous people do, because unlike some people he doesn’t have the decency to go and talk to teenagers and find out the truth, or maybe there aren’t any brains in his head. Either that or HIS parents didn’t bring him up properly. His parents probably didn’t teach him basic manners and he doesn’t know what being polite is. Interestingly enough, as I was reading on I noticed how conceited and arrogant he was when discussing the parenting skills of these teenagers.Jeremy states that ‘Nothing can be done about the parents because they are too thick’. Yes, he is attempting to be humorous, but there is truth, in his eyes, in what he is saying and it is offensive! I strongly disagree with him because pare nts have the intelligence to do anything for their kids and help them through their lives. I was actually very enraged at this, I can tell you that my parents are NOT and I repeat NOT thick. Rather they are very intelligent because to raise a baby into a grown female/male with basic manners and high morals takes a lot.I can understand why he is thinking like this because he didn’t have a very happy ending of the encounter with the teens but common who needs all of the aggression? He starts off by branding teenagers as brutal thugs who love drink a lot of cider and love to stab passers-by. When i read this i feel really outraged that he has the audacity to say such things, I mean how the hell does he know all teenagers are like this. I can confirm to you that i am a teenager and me and my friends don’t drink vast quantities of alcohol or love to stab passers-by as a hobby.I have to say he is being really ignorant because he’s trying to make teenagers look all vio lent and what’s really weird is that the teens didn’t touch him but he just thought he’d just grab the ringleader by the scruff of his neck. Now what do you call that? I say that’s what you would call a ‘middle age thug’. Now there is no way you can disagree with me he was the aggressor there, he just assumed it was ok to enforce violence on a group of teens who hadn’t even touched him.

History of African American Music

The history of African American music has been characterized by a mixture among various forms of music. Country blues, urban blues, New Orleans Jazz, Bebop, big-band jazz, and rhythm and blues, have all influenced each other profoundly. These influences flowed back and forth among the various forms. But, black gospel music had only a very limited effect on popular styles, until a few church-trained artists, such as Sam Cooke and Ray Charles, began to incorporate gospel styling into their popular work.The result is usually described as â€Å"soul music,† a mix of blues, rhythm and blues, and gospel voices. But, if Ray Charles was one of the â€Å"originators† of soul music, â€Å"Aretha Franklin reshaped it,† by bringing even more of her gospel background to bear on secular love songs (Wade and Picardie 27). By combining popular elements with her stunning voice, her great musicianship, and the feeling for a song that she learned in church, Aretha became one of the greatest soul singers to ever live. Aretha Franklin is a well-known pop, R&B, and gospel singer.She has been nicknamed â€Å"The Queen of Soul† and is an internationally known artist and a symbol of pride in the African American community. Her popularity soared in 1967 when she released an album containing songs â€Å"I Never Loved a Man†, â€Å"Respect†, and â€Å"Baby I Love You. † Throughout her career she has achieved fifteen Grammy Awards, Lifetime Achievement Award, National Academy of Recording Arts and Sciences Legend Awards, and many Grammy Hall of Fame Awards. In 1987 she became the first woman inducted into the Rock & Roll Hall of Fame.Time magazine chose her as one of the most influential artists and entertainers of the 20th century. She sang at Dr. Martin Luther King’s funeral and at former President Bill Clinton’s inaugural party. Although she has all these accomplishments and awards there are other reasons that have driven Fr anklin to fame and landed her on the front cover of Time magazine on June 28, 1968. The reasons I believe allowed Aretha Franklin to become so successful are the following: Her family’s involvement with religion, the inspiring people that surrounded her, and the pain she suffered.It is clear that because her family’s involvement with religion would be one reason why Aretha Franklin became as famous as a Gospel singer. Some people would say that her love for religion is unbelievable, but after researching her childhood it is very believable. Her father, Reverend Clarence LaVaugh Franklin lived in Shelby Mississippi and preached while living the life of a sharecropper. As soon as he had enough money, he would move to Memphis, Tennessee to become a pastor of two churches. After a couple of years he attended LeMoyne College, and he studied Education and English Literature.With his education he was able to bring a more liberal view to his preaching’s. Then he moved t he family to Buffalo, New York. When he had the resources, he moved the family again to Detroit, Michigan were he settled and became a pastor of a churched called New Bethel Baptist Church. He quickly became one of the most famous pastors in the city of Detroit. Aretha was two years old when they made their final move, she would grow up here and grab the emotion of Church and incorporate it into her music. Aretha Franklin’s mom, Barbara V. Skaggers, served as choir director and pianist.Aretha describes her mom as â€Å"a Superb singer, her voice was clear and distinctive†. (Franklin and Ritz, 6) Her parents taught her how to sing with great pride. This was a big issue because the late ‘50s, early ‘60s was a time of turmoil for African Americans. Her father especially tried to instill pride into her. He was a Civil Rights activist and he was a close colleague with Dr. Martin Luther King. With her parents keeping her involved in Church she was bound to become one of the world’s greatest singers. At around age 12, the father recognized Aretha’s talent as a singer.So he took her on the road with his traveling gospel show. This was important because it shows the kind of support Aretha received from her family. It was said, â€Å"She was a spellbinding performer at the age of fourteen. † (Franklin, 3) So her family really supported and inspired her to become a gospel singer. What also made her a great artist was that she had inspiring people all around her. Aretha grew up in Detroit which at the time was a rousing city or a city of hope for the African Americans running away from the brutality of the South.Though Detroit still had its problems such as race riots, many famous musicians grew up there. Also since New Bethel Baptist Church was so prominent, many musicians and political leaders used Reverend Franklin’s pulpit as a platform to sing or speak to the Black’s of Detroit. Aretha was introduced to cla ssical music by Smokey Robinson’s sister Sylvia Burston. She listened to well known local DJ’s like Ruth Brown and Senator Brystal Brown. When Aretha was younger, she would ride her bike to the local park, and on her way home she would stop by a night club where you could here B.B. King perform. She says, â€Å"You could hear the soft sound of his guitar all the way to the sidewalk (Franklin and Ritz, 22). National and local political leaders would give there speeches. Speakers such as Dr. Adam Clayton Powell, Sr. , Dr. Martin Luther King, and Reverend Jesse Jackson would speak powerfully to the church. Aretha was directly influenced by Miriam Anderson, Sammy Davis, and Roy Wilkins. Detroit was overflowing with talent and speakers which I believe also contributed to Aretha’s success.Pain was probably what really drove Aretha Franklin’s success. As stated before, Franklin’s family was highly religious and was continually involved in the Church. But that doesn’t mean that she hadn’t been through a tremendous amount of pain. Early in life her mother and father got a divorce. The father was better suitable to raise Aretha and her four Siblings. The mother moved to Buffalo, New York and tried to make regular visits to see her children. She was supported her children in the best way she could, but when Aretha needed her, she still was not reachable.Matters became worst a few years later when Aretha’s mom dies of a stroke. Aretha described her mom by saying â€Å"she was the absolute lady† (Smith, 3). At age 15 she had her first child and two years later another would come. But Aretha still wanted to go out and be with friends, so her grandmother usually babysat for her periodically. In a time when Black Activism, Feminism, and Sexual Liberation were high, she needed to provide for herself. So when Aretha was old enough and was ready to start performing, she hired a man named Ted White to be her manager. He later became her husband. In the future she would divorce him for a famous actor which would end in divorce, too. Even though in 1968 to 1969, Franklin’s career was rising rapidly. She was still described by her Producer Jerry Wexler as â€Å"a person whose depressions runs deeper than the sea† (Ritchie Unterberger, 3). Then one of Franklin’s highest admirers, gospel giant Mahalia Jackson died. Right after her death a extremely emotional gospel album was released my Aretha â€Å"Amazing Grace† This record was considered to be one of the most emotional records of its time.Much of the pain that Aretha suffered was not really publicized, but still it had to be one of the reasons for her to have such a powerful voice. Aretha Franklin was a successful artist and still inspires musicians today. Her voice is still described as incredible. She has all the awards that she needs to show her talent.

Deutsche Bank is a global universal bank. What are the advantages and Essay

Deutsche Bank is a global universal bank. What are the advantages and disadvantages of a global universal bank and what are som - Essay Example The Deutsche bank holds a record for being the only bank that has strived to achieve omnipresence. Evidently, universal banks exhibit multiple benefits to the clients, but a closer analysis reveals that they have certain disadvantages. This paper will highlight the advantages and disadvantages of universal banks. Moreover, the paper will analyse the issues that arise when handling tasks in the compliance department. Advantages of Universal Banks Universal banks offer their clients a diverse range of services to different clients having the opportunity to receive personalized services that conform to their banking needs. Usually individuals, groups, organizations, states and multi-national organizations exhibit varying financial needs. The fact that universal banks have the capacity to offer tailor-made services, they surpass other banks by offering each client service that conforms to personal financial needs. This is the reason why universal banks offer a high level of convenience t o the clients (Heller, Meaney & Murphy 2001, p. 78). They serve as a single-stop banks where one can access all the required financial needs. Evidently, such convenience receives emphasis from the presence of most universal banks in different regions, affording the clients an increased banking flexibility even beyond the borders. Recent research reveals that universal banks serve as critical contributors to the economy. This is because they have the capacity to support a diverse range of investments in different parts of the globe. Universal banks exert their effect on the entire economic system, altering the economic trends by providing financial breakthroughtwo different types of clients. Universal banks serve private household clients, offering arrange of appealing service packages appropriate for them (Palepu2007, p. 87). Moreover, universal banks offer a range of services to institutional clients empowering them to receive the required the financial boost to achieve their goals . This factor has served as a reliable solution to the financial problems of many institutions as they can form investment partnerships with universal banks. These services are offered at a relatively lowered funding cost compared to other banks. Evidently, universal banks register a low level of profiling costs, placing them in a better position to offer services at the lower funding cost compared to other banks. Moreover, these banks exhibit a lower funding cost themselves, explaining further why they favour all types of clients. Universal banks have served to increase the willingness of credit borrowers, a factor that has contributed to the rising returns for clients who wish to save. This has been especially advantageous to governments that exhibit financial needs that require borrowing. Moreover, this proves to be highly beneficial to other clients, and contributes to a surging growth. This has given rise to an evident rise instability of the economies by causing as the spread of innovations in different regions in the globe (PadoanBrenton & Boyd 2003, p. 34). Disadvantages Although universal banks exhibit all these benefits, they face a surging pressure to satisfy all the clients in different regions.These banks face the compulsion of maintaining a high quality of their services (Lambert&Ioma2005, p.98). They have to ensure that they are responsive; clear in communication, prompt, and a high level of integrity in offering

The Trio Sonata in the Baroque Period Essay Example | Topics and Well Written Essays - 3000 words

The Trio Sonata in the Baroque Period - Essay Example Trio Sonata is an instrumental piece [consisting] of two, three, or four successive movements of different character, which has one or more melody parts, with only one player to a part [i.e., "einfach" as against Mattheson's "stark," for multiple performance of the parts; Cf. SBE 25]. Depending on the number of concertante, melody parts that it has, a sonata is described as [being] à   solo, à   due, à   trà ©, etc. Clearly, in no form of instrumental music is there a better opportunity than in the sonata to depict feelings without [the aid of] words. The symphony [and] the overture has a more fixed character. The form of a concerto seems designed more to give a skilled player a chance to be heard against the background of many instruments than to implement the depiction of violent emotions. Aside from these [forms] and the dances, which also have their special characters, there remains only the form of the sonata, which assumes [any or] all characters and every [kind of] express ion. By [means of] the sonata the composer can hope to produce a monologue through tones of melancholy, grief, sorrow, tenderness, or delight and joy; or maintain a sensitive dialogue solely through impassioned tones of similar or different qualities; or simply depict emotions [that are] violent, impetuous, and [sharply] contrasted, or light, gentle, fluent, and pleasing. To be sure, [even] the weakest composers have such goals in the making of sonatas, among the weakest [being] the Italians and those who imitate them. The sonatas of the present-day Italians are characterized by a bustle of sounds succeeding each other arbitrarily without any other purpose than to gratify the insensitive ear of the layman, [and] by sudden, fantastic transitions from the joyous to the mournful, from the pathetic to the flirtatious, without our getting what the composer wants [to say]. And if the performance of these [sonatas] engages the fancy of a few hotheads, the heart and imagination of every lis tener of taste or understanding will still remain completely untouched. A large number of easy and hard keyboard [i.e., clavichord] sonatas by our Hamburg [Emanuel] Bach show how character and expression can be brought to the sonata. The majority of these are so communicative ["sprechend"] that one believes [himself] to perceive not tones but a distinct speech, which sets and keeps in motion our imagination and feelings. Unquestionably, to create such sonatas requires much genius [and] knowledge, and an especially adaptable and alert sensibility. But they also

The importance of jazz in American culture Essay

The importance of jazz in American culture - Essay Example The origins of jazz may lie in the blues rhythms that developed in the period immediately following the American Civil War and the emancipation of slaves. The distinctive element of the blues is that through the performance of a solo artist, an attempt is made to translate emotions into music through humming, moaning, and soundless effects added to the actual words of the song (Halim, No Date). Jazz developed from the blues, but it differed from the blues in that it had a more cheerful, uplifting note within it. In the words of Stanley Crouch, jazz historian and critic, the love for the music felt by both white and black communities helped to make jazz â€Å"a futuristic social force in which one was finally judged purely on the basis of ones individual ability. Jazz predicted the civil rights movement more than any other art in America." (Hentoff, 2009). It was in essence a tool to reach out to people everywhere, irrespective of their color and therefore a tool that could function as a means to break down segregation and lead to the development of a non-segregated society. Lewine (1992) has described how jazz slowly became synonymous with popular culture. America emerged into the 20th century as a society where culture was necessarily associated with the high brow, more genteel sections of society. But jazz entered this cultural arena as a vital new element that was so distinctive that it appeared to be â€Å"the new product of a new age†, while culture appeared to be traditional, having developed over the centuries (Lewine, 1992:7). Yet, culture and jazz appeared to define each other, because the emergence of this new form of music which was (a) spontaneous (b) raucous and (c) participatory in that the audiences joined in vigorously, and its enormous popularity redefined the entire element of what constituted culture.

Navigation app for iOS Literature review Example | Topics and Well Written Essays - 750 words

Navigation app for iOS - Literature review Example This framework is designed to work with the newly introduced M7 coprocessor that is dedicated to handle motion sensors without reducing the battery performance of the device. It gives the developers accurate data about the users, which they can later make use of in their applications. For example, a developer can find out whether the device is currently with an individual who is in the act of walking, or with someone who is travelling in an automobile etc, without actually processing the accelerometer’s data. Core Motion Framework provides answers to such questions through constants defined by the classes of framework. â€Å"Now Core Motion has been around since iOS 4.0, but the iOS 7 includes the new classes needed to access data from the M7. The two main classes used here are CM Motion Activity Manager and CM Motion Activity. These two classes work hand in hand to make work the motion activity updates† (Graves 2014: 1). Most iPhones contain an accelerometer and 3 axes Gyroscope built into them, which provide the device with 6 operational axes when used together. This axis data and motion data populated by the M7 co processor could be used along with Map kit or any other third party Map API to create great navigation apps. The gyroscope data as well as gravity sensor data are also used for building motion sensitive gaming-applications. Various class references of Core Motion framework include â€Å"CMAttitude, CMAccelerometerData, CMDeviceMotion, CMGyroData, CMLogItem, CMMagnetometerData, and CMMotionManager† (Aguinaga 2013: 9). The Map Kit framework is used for embedding custom maps into iOS application windows. The 5.1 version and the previous ones basically made use of Google Maps API for displaying the maps through the MapKit framework. â€Å"This framework also provides support for annotating the map, adding overlays, and performing reverse-geocoding lookups to determine placemark information for a given map
