Science, Technology & Innovation Systems - Essay Example In places where there is no sufficient level of wind, the wind turbine industry certainly cannot operate efficiently and effectively. It requires strong level of wind in order to generate enough amount of electricity from wind energy. Electricity is very important in the society particularly in industries, households and every establishment. This means that electricity is an integral part of every political, social, legal, technological, economic and environmental aspect of the society. This is the reason why every nation tries to come up with the right level or amount of supply of electricity for everyone. Around 21.40 percent of electricity in Denmark is derived from wind. Compared this from the United States and other countries in Europe, this is relatively higher and only implies that Denmark has remarkably relied heavily on the wind-turbine industry in its electricity generation aside from other energy source. Certainly there are some important reasons why the wind-turbine indus try in Denmark became so strong. It is the main point of this paper to present some of the factors that contribute greatly to the success of wind-turbine industry in Denmark. ... Furthermore, the proponent includes the characteristics of the innovation system and the corresponding impacts on other sectors and technologies. Main actors, linkages, institutions The world is currently faced with the issue of global warming which is said to be as an upshot of human’s economic activities over the long span of time. What was the most intriguing is the issue about the higher amount of greenhouse gases emitted by electricity generation through fossil-fuel based of generating electricity. In Table 1, it is shown that different countries in Europe have substantially contributed higher amount of greenhouse gases emission due to on-going economic activity. However, the good news is that most of the fossil-fuel based of generating electricity can be replaceable by other alternative energy source. These fossil-fuel based of generating electricity can be replaceable by wind as shown in Table 2. Shown in Table 3 is the specific information about the percentage of elect ricity produced out from wind energy in the United States, Denmark and other countries in Europe. Table 1. Specific average emissions (CO2, SO2, NO2) from fossil fuel-based electricity generation in the different EU-27 Member States in 2007 (European Wind Energy Association, 2009) Table 2. Fossil fuel-based electricity generation replaceable/avoidable by wind (and other renewable electricity generation technologies) in the EU-27 Member States in 2007 (European Wind Energy Association, 2009) Table 3. Percent of Total Electricity Derived from Wind in 2006 (Asplund, 2008) The European Wind Energy Association is very particular with sustainability and eradication of factors that slowly affect the environment in particular.

Expected U.S. GDP growth rate going forward Essay Example for Free

Expected U.S. GDP growth rate going forward Essay This paper examines the expected growth of the United State’s GDP.   It looks at how the economy is performing, especially after the recent credit crunch that had effects on the whole world’s economy. The paper looks at GDP growth rates expected at different rates for specific periods of time.   According to the World Bank, the economy of the United States of America is the largest amongst the world’s economies. Expected U.S. GDP growth rate going forward Economic growth is a situation in which the value of goods and services produced by a given economy. It is measured in terms of GDP where it is taken as the percentage rate of rise in real GDP.   Growth is an economic parameter that is presented in real terms; this means that it varies according to adjustments in inflation-terms so that the effects of inflation on product prices can be netted out (Lipsey, et al, 2007).   The average living standards of citizens of a nation are measured using real GDP per capita calculated as the total GDP divided by the total population in an economy. Considering the recent economic activities, the economy was on a go slow during the second quarter due to the fact that consumer spending was adversely affected by job scarcity. This condition left the recovery to almost solely dependent on the flow in commercial investments. According to updates of July 28, 2010 by Economic Outlook Index, it predicted that the economy will experience growth in real Gross Domestic Product at an annualized growth rate based on six month period. However, after the end of stimulus initiatives, it is expected to slow to about 2.5% by the end of December 2010. This situation will be greatly influenced by the seemingly perpetual high unemployment, the feeble housing market, high debt and rigid credit. The GDP of U.S., and of course other economies, can be determined either by finding total demand in the economy, total production or total spending. Using total spending, it is projected that during 2010 the total spending will be $6413 billion. This represents about $378 billion or 6.26% increase based on the previous projections of 2009. This is also expected to continue rising in the subsequent years. For instance, the total spending is expected to hit $6713 billion and $6832 billion in 2011 and 2012 respectively (U.S.A. Government spending, 2010). The implication of this is that the U.S. GDP can be expected to grow at the rate 6.26% in 2010, 4.68% in 2011; this represents a drop from the preceding period and in 2012 it is expected to grow at the rate of 1.77% (U.S.A. Government spending, 2010). This means that even though the real GDP is expected to grow between 2010 and 2010, it will happen at a reducing rate. Even, So, some of drivers of the projected growth include the expected increase in employment for the period running from 2008 to 2018 in which   unemployment is to reduce by 10.1% and increased government expenditures amongst other significant economic factors. It is therefore important to note that there is no cause for alarm amongst the business community and the investors. Conclusion The recent credit crunch which started in 2007 affected the U.S.A economy alongside other major world economies hence sending ripple effects to the developing economies (International Monetary Fund, 2008). More jobs were lost during the period, the prices in the real estate market experienced high inflations and generally the cost of basic consumer products went up. However, through stimulus strategy and other economic interventions has seen the U.S GDP growth start increasing. This is due to projected growth in total expenditures and commercial activities within the U.S. economy. It is also expected that unemployment rate will go down and hence have a positive effects on total expenditures.

Theories of Defence Mechanisms and Psycho-Sexual Development

Theories of Defence Mechanisms and Psycho-Sexual Development Psychoanalysis A discussion on what’s inside Chung Dennis Psychoanalysis’s definition is the study of a comprehensive theory pertaining to the process of understanding human nature, motivation, behaviour, development and experience through the exploration of the unconscious thoughts of the human mind. It is governed by rules of understanding whereby each individual is unique at birth, there social media, and other external factors outside and not within the persons awareness or control (Unconscious thoughts, feelings and experiences) that influence his or her thoughts and actions, that what happened during the childhood and other early experiences echoes and affect the outcome of the individual during the adolescence and mature stage of life that ongoing experiences in a persons life are always engaged and ongoing in the process of development through their lives. (American Psychoanalytic Association 2009 2014) These are the 5 key concept of psychoanalysis that I am focusing on. First, there is the concept of personality construction regarding the 3 basic ideas of the ID, Ego and Super Ego as according to Sigmund Freud. The id is the component of a personality that is already there from birth. The aspect of personality is unconscious and includes the instinct and primitive behaviours. According to Cherry, K. (2014.), the id is a psychic energy that makes it the primary component of personality. This personality that drives the individual is instinctive and it is by Sexual and Aggression energy. The ego is a component of personality that is guilty for dealing with what is the reality. According to Cherry, K. (2014), the ego develops from the ID and ensures impulses of the id personality can be expressed possible and acceptable manner in society. This personality is shaped by the influences or the outside word by the means of society, trends and also social media. (Cherry, K. 2014.) In accordance in her book, Cherry, K. (2014) states that the Super EGO personality is broken down into two parts, the two parts that affect the outcome of the superego in the individual is firstly, The EGO idea, where it sets the rules and standards for good behaviours through the upbringing and social circles that the individual is in. These behaviours include those which are approved and set by the parents and other higher authority or social figures. And by so following the rules set by them it give the person feelings of value and accomplishment. The part of the conscience come into play whereby it includes information about things that are viewed as unaccepted in terms of the magnitude portrayed by the parents and by society. These behaviours and actions will then be followed on by bad consequences, punishments or guilt and remorse. The Second key concept is the presence of Defence Mechanism, Defence mechanisms are manners and methods in which we behave, think and react in certain ways to better protect and to distance one selves from a being fully awareness of unpleasant thoughts, feelings, actions, morals or behaviours. (Grohol, J. M. (2013)) In Grohol, J. M. (2013) article, he states that psychologists have categorized defences mechanisms depending on how primitive they are. The more instinctual they are the more effective they are against in the context of short-term denials, and hence are favoured by many people and amongst children especially. The few defence mechanisms are; Firstly denial, the refusing to accept the facts or reality. Therefore by so doing, arguing an anxiety and by provoking stimuli and in its reaction, stating it does not exist then thus blocking it out. (Heffner C.L. (2001)) Secondly, repression. It is a mental reaction state that returns the individual to a previous stage of development. Reactions varies from crying in a corner when being sad to throwing a temper when thing are not going their way. The third defence mechanism is intellectualization, it supplies a logical and or rational reason as in relations to the actual conscious reason, therefore, theories and logic are given for a clinical explanation to the situation of behaviour instead of reality The forth defence mechanism is projection, it is an extrovert reaction by throwing† the bad emotions (anger, frustration, sadness) unto another person feeling the opposite, by so doing, making themselves feel better than the affected individual. The last but not least defence mechanism is sublimation. It is the transferring the anxiety of the situation into a more positive energy and therefore coping with the problem better. For example as given by Heffner C.L. (2001) diverting ones aggressive impulses toward a career as a boxer, becoming a surgeon because of your desire to cut or by lifting weights to release aggressive energy We then move on to one of Freud’s theories which are the psycho-sexual development of an individual. It describes how personality develops during childhood. However, these are still a controversial theory. It revolves around the ID becoming very much focus on the specific erogenous areas. The psychosexual energy, also known as the libido, is the driving force behind behaviour in every individual. It revolves around these 5 stages: The Oral stage that revolves at the time of birth, it revolves around the mouth of the baby; fixation or restrictions in oral might result in having a passive, gullible, immature,manipulativepersonality. (Sim, M. 1974) The Anal stage revolves around the bowels and bladder eliminating of waste from the body. Being fixated at this stage might lead to being Anal Retentive (Being too organized) or Anal Expulsive (Being too unorganized or reckless) The Phallic stage starts at the age of six; the individual starts to discover the genitals of his or her body. Then after which he or she will compare it to their mother or father, whichever gender that poses a threat or competition. For example, the son is being jealous of the father for the right of the mother and the daughter being jealous of the mother for the right of the father. The Latent stage happens from age 6 to the stage of puberty. It is the consolidation of the entire lesson learnt and habits picked up from the previous three stages where the child would then develop his or her own thinking and therefore start consolidating it into his own EGO and thus creating his or her own drive with the influences of the ID. The last stage also known as the Genital stage, stretches across the spam of the entire life of the child as he or she breaks his bond and becomes independent from the parents both psychologically and sexually. The child then squares off with the ID and EGO to come out with a more intellectual side of his thinking process, to relate through friendship, love relationship. Psychoanalysis also emphasises on the role of the unconscious or according the Corey. G. (2012) a slip of the tongue is also known as the Freudian Slip is a lapse of the mind where by the unconscious is somehow surfaced without the person actually realising the meaning of it but to the therapist, he can interpret it as something hidden and known to the mind. It is influenced by a number of disciplines, including psychology, sociology, anthropology, literature, and art. (Cherry, K. 2014.) According to Cherry, K. (2014) Freud divided it to three levels of mind in comparison to an ice burg. The top or the surface portion of the iceberg above water represents the conscious mind. The halves submerge part of the iceberg that is the bridge between the unconscious is also known as the preconscious, it is known to house the anxieties and defence mechanisms as the guardians of the bridge. The rest of the submerged part of the iceberg is hidden, unseen beneath and is known as unconscious, only by going through or in the absence of the ‘Guardians’ also known as the defence mechanisms and anxiety, only then will the unconscious can surface and be tapped into . The last factor is in relations to the childhood development is stating and supporting the theory that whatever happens during the psycho-sexual stage of the child’s development. It states that the fixations of the child when they are young will echo and cause them to construct habits of their own uniqueness according to what they were fixated with. Psychoanalysis in modern therapy revolves around the practice of free association and the skill of the therapist on how he deciphers and organise by working on and the interpretation of dreams and fantasies. This therapy is also costly and requires a lot of time as the deriving of the unconscious cannot be done at one go. The therapist must also try to identify the resistance and the defence mechanism in the client in order to allow the unconscious to be conscious and by so doing making him feel safe with no anxieties or criticism that will trigger him back into the state of psychological self-defence. For example in Newirth, J. (2013) book, he is using psychoanalysis in in the means of developmental hermeneutic approach. That is one way that modern practitioners are inculcating psychoanalytic therapy into their own way of therapy. Advantages of psychoanalysis are that through its therapy and analysis whereby through the unconscious opens up a window to get to the root of the problem. It helps control and constructs the ID, EGO and Super EGO of the individual. Through the construction of the individual’s personalities, it allow the change of feeling and also the change of the person’s behaviour and mentality towards all things around him as he is more in control of his ID, EGO and Super EGO However, there are disadvantages of this therapy as it requires a long time to treat the fellow individual and as it requires many sessions in order to understand and analysis the unconscious thoughts of the individual. Thus, having more session which requires more money per visit. It also states that there aren’t much therapist trained in the field of classical psychoanalysis as it takes loads of experience in the field in order to be good as a therapist in interpreting the unconscious thoughts of a person. Though analysing the unconscious and memories of others, it also contradicts to the memories as the person cannot recall till his childhood and in return tell fake memories to fit the bill. Last but not least, in this modern age where personal information is of a high privacy to us, tell someone that we do not know of, our memories, problems and the unconscious who make some of us very uncomfortable and more likely to not do the actions that make us reveal or private infor mation and that could hurdle the psychoanalysis therapist. In conclusion, psychoanalysis therapy is a foundation for all psychotherapy as it lays a firm and concrete concept in the evolution of identifying the roots and the analysis of the mind and personalities that an individual has. It also lays down the rules that every individual is unique and every problem can and must tackle and resolved differently.

Sacrifice and the American Dream in the Works of E.L Doctorow Essay

Sacrifice and the American Dream in the Works of E.L Doctorow      Ã‚  Ã‚   Throughout the works of E.L. Doctorow, many facets of American society are explored, ranging from the plight of the homeless to the idiosyncrasies of the rich. A persistent theme prevalent in all of his novels is the existence of the American dream. He seems fascinated by upward social mobility, especially when it involves the impoverished and underprivileged. Yet Doctorow also points out that with the success or attempted success of the American dream, one must make sacrifices, compromising morality, physical well-being, conscience, or identity. The overall benefits, though, of achieving prosperity, equality, or acceptance seem to always outweigh the adverse affects that result from chasing the enduring dream.      Ã‚  Ã‚   In his most acclaimed novel to date, Doctorow tells a "story of the intersection of three very different families"(Weiss n. pag.) during the gilded era of the 1910's. Titled after the ubiquitous music of the decade, Ragtime chronicles the clashing social, economic, and political ideas that plagued the beginning of the century. The three seemingly separate families provide a cross section of the diverse American culture predominating this period of history. The first household represents the White Anglo-Saxon Protestant(WASP) culture, one which supposedly has already achieved the American dream. The other two families represent certain ethnic and racial groups who strive to attain the dream throughout the novel. But in pursuing this, they are each forced to pay a certain price.         Ã‚  Ã‚  Ã‚  Ã‚   In most of his novels, Doctorow seems "particularly compelled by the stories[of]...poor immigrants"(Righteous 112); Ragtime is no excepti... ...September1980. pp 38-40.

Retorhical Argument

Zoe Mojica Ryan Grandik English Comp. II February 27, 2013 Rhetorical Analysis (why violent video games are good for girls) Student Carmen Tieu, in her opinionated article, â€Å"Why Violent Video Games are good for Girls† expounds upon the idea that violent video games are good for girls. Tieu explains that violent video games boost confidence in women. She goes further on to say that it makes aware of the different socialization processes of men and women. Tieu begins by telling a short story about her gaming life. She is attempting to give you a peek into her mind about being a girl playing first person shooting games.She begins to reveal that men and women are socialized differently by using the aggressive chatting being done before the game begins. Tieu speaks to us in this manner to help us experience what it is like to be a girl and to be playing the violent first person shooting games. The way she is saying this makes it seem as though all males playing these games all act in such ways. The way that Tieu tells her story in the first paragraph gives us a more biased or more sympathetic affect to her cause. After Tieu finishes her first person perspective of the shooting games, she begins to say that girls are socialized into more docile activities.The language of the text that the writer is using is trying to make you more sympathetic towards her goal of this paper. Her word choice is meant not only for you to be sympathetic but to cause vexation. Tieu illustrates how society thinks that women shouldn’t and can’t play video games by saying they â€Å"objectify women† and the â€Å"violent† nature â€Å"repulses† girls. Tieu creates this tone by saying â€Å"Girls are socialized into activities that promote togetherness and talk, not high intensity competition involving fantasized shooting and killing. † Tieu continues to explain that women can play, and be just as good as men in violent video games.Carmen Tieu says that playing first person shooting games are empowering because it gives girls a chance to beat the boys at their own game. Her overall tone is meant to excite and make you want to play first person shooting games such as her quick and instinctual reactions using both joysticks. The author creates a very powerful environment when she explains how she gets an adrenaline rush beating testosterone driven men at something they are supposed to â€Å"excel† at. The writer creates a passionate diction when she uses the â€Å"savor† and â€Å"horror† and â€Å"completely destroys them†.The author furthers the goal of her paper by making her victory seem so empowering. Tieu proceeds in this paragraph by elaborating on how women can be made more confident in other aspects of life by playing violent video games. She says that when women play video games they are freed of the stereotype that women are meant to be soft and motherly figures. She claims that s he doesn’t reject these because she is a vegan and a tree hugger, but by saying she understands the opposing view makes it easier for the reader to stay on her side as to why video games are good for girls.She goes into further detail by saying it has psychologically helped her because she is aware that she can beat males at â€Å"their own game† claiming that it gives her more confidence in the male dominated academic field of math and science. Tieu says in this paragraph that playing video games has given her a different way of bonding with guys. She uses the example that a man gave her his respect for playing video games but goes on to say that he didn’t really respect women in general but we can’t really tell if he’s that kind of man just by one sentence.Showing the â€Å"lack of respect† he had towards women, she goes on to say since she started playing video games men have a different way of talking to her. Her way of saying â€Å"You get joy from perfecting your skills so that your high-angle grenade kills become a thing of beauty. † makes it seem as though it becomes a boost of confidence much like winning in a physical game. Tieu begins this paragraph by saying violent video games give girls an insight to a disturbing part of the male subculture. She uses words like â€Å"homophobic† and â€Å"misogynistic† to describe how the men react when they are playing such violent games.She describes them in a way that makes all men who play video games seem as though they downgrade any player who is below or even above them. She goes on to say that when she beats her male friends they are embarrassed by it which turns them into â€Å"testosterone driven macho men. † Tieu suggest that when men are around a female one on one a softer side of them comes out. She also over uses the word â€Å"macho† which creates a dual reality of how men can be a lot shallower when playing first person s hooting games. By her using the words to be a real man† she gives the claim that when men are around other men they have to pretend to be far more manly versions of themselves then what they really are. In contrast though, men are able to act like their true selves when they are one on one with women. When she uses those words to create the dual reality between a real man and a fake man she’s creating a tense environment and leaves us with an open question: Which man is the real man? In this opinionated article, â€Å"Why Violent Video Games are good for Girls†, Carmen Tieu argues how women should play violent video games.She uses diction and tone to help promote her argument. Throughout this article, she lets the reader know how much she has learned about the two natures that men display. Her words show how proud she is that she is able to recognize this difference in behavior and that she did not succumb to this, â€Å"ugly phenomenon†. The overall tone of the paper was persuasive and led you to be sympathetic to her cause. The type of language that the author uses helps to further enhance the argument. Through rhetoric devices Carmen Tieu solidifies that video games can boost confidence in women and that men and women are socialized differently.

Harlem Renaissance Music Essay

Harlem Renaissance refers to the development of African-American arts and culture in the United States, immediately after the World War I. According to reports, the revolutionary development in the arts and culture started in Harlem, New York, thus the name â€Å"Harlem Renaissance. † Harlem Renaissance is believed to have happened between years 1919 and 1930, with 1924 to 1929 as the years when it reached its peak (Charters S. and Kundstadt L. ; â€Å"Harlem Renaissance†). The initiators and participants of the Harlem Renaissance movement include the descendants of different societies who had witnessed and first-handedly experienced slavery. Most of which were Africans or people of African descent. Others were migrants from certain racial communities and were seeking for their place in a relatively â€Å"unprejudiced† society in the United States. What was common among the participants of Harlem Renaissance was their desire for the change especially in terms of racism and African stereotyping. The union of these people based on this one value had been the seed of Harlem Renaissance which then became a major influence on not only on people with African roots across the world but also on the culture of America (Hutchinson,G. ; â€Å"Harlem Renaissance†). In challenging the specter of racism, prejudice and African stereotyping, the participants of Harlem Renaissance invoked the power of cultural tools such as literature, art and music to represent a â€Å"different† African-American who is both intellectual and productive, and in effect initiate their integration in society without any racial barrier. Part of this revolution was to uplift the spirit of the race by unifying their culture. The media of Harlem Renaissance would hold no definition for â€Å"high-African culture† or â€Å"low-African† bringing forth a new wave of artistic forms of arts and literature, thus the rise of modernism; and in particular, music, which gave birth to blues and jazz (â€Å"Harlem Renaissance†). Harlem Music Blues Blues and Jazz are two types of music that have developed in the Harlem Renaissance period. Blues, as its name implies represents music that evokes sadness, especially that inflicted by difficulties in life and love. Blues is said to have evolved from the usual African hollers and by itself, could provide the listener with an insight of the history of African Americans from being communized to the emergence of individuation. Individualized or solo songs had never been usual in the African culture and the uniqueness of the characteristics of blues represents the then changing status of African-Americans: their freedom (McElrath, J. ). In blues, the individual is emphasized making this type of music a form that can be called â€Å"personalized. † Still, even though blues can be said to be far from the typical African music, some elements of the cultural type are still present in this new form. This is what characterizes blues as African and what gives this musical form a sort of â€Å"nationality†. The â€Å"call-and-response† characteristic of the African hollers for example are still present in blues, although has been somehow reinvented to fit in the characteristics of blues. In blues, responses are made not by another participant or some other external force but by the performer herself (McElrath, J. ). To reinstate, the characteristics of blues are a representation of the new African who is more self-assured and individualized. Blues singers are usually accompanied by guitars or harmonicas (â€Å"Harlem Renaissance†). Blues started as â€Å"folk blues† sung at leisure, medicine shows and touring carnivals. It became â€Å"classic blues† as it was given professional quality by African vaudeville singers who corresponded with the folk singers. With the African-American migration to the North in early 20th century, is the blues music (Hutchinson,G. ). Blues music first came to New Orleans. With the inter-state migration of different musicians, the Blues music was scattered and was able to come to Texas, Louisiana, Arkansas, Chicago, Detroit and then New York where different Blues musicians started to unite and popularize the style as they perform in different clubs, theaters and dance halls (McElrath, J. ). Again, as blues became a representation of the African’s new-found freedom not only from slavery and prejudices but also from the dogmatic imposition by institutions such as churches, the popularization of the music did not become difficult. It was easily appreciated especially by those with African descent who were craving for entertainment, thus, the start of theaters and other entertainment halls (McElrath, J. ). It was in 1920 when the music became popular with Mamie Smith’s â€Å"Crazy Blues† and â€Å"It’s Right Here For You. † Blues music was at first marketed only to the African community but as music companies decided to exploit the opportunity to enter the new market, other artists like Bessie Smite, Ma Rainie, Alberta Hunter and Ethel Waters sprang up and became popular blues performers (McElrath, J. ). As blues music continued to evolve, it gave rise to a new type of music which is now popularly known as jazz music. Jazz Jazz is considered as the characterizing music of the Harlem Renaissance. This type of music may appear to be simple for untrained ears but actually involves unknown technicalities that continue to become part of the present American culture (Schuller, S. ). Jazz works based on the theory that any chord progression could be played using infinite amount of melodies. It involves talent and improvisation by both the singer and the instrumentalist, with the singer doing repeated chord progressions and the instrumentalist doing variations of vocal styles and tonal effects. The result is the collaboration of two improvisations in a single music (Schuller, S. ). As said earlier, blues contributed to the development of jazz. It can be noticed that blues themes and forms are incorporated into jazz music. This gives jazz music an African character. What characterizes jazz as a truly unique type of music, even from blues, is the flexibility in which it can be played. There are no rules in rhythm that must be followed allowing the each individual performer to become flexible and free in creating his or her own rhythm. The most common instruments used by jazz performers are piano, drums, strings and bass. The use of saxophones in jazz is usually connected to an evolutionary product of jazz called the Chicago style (Schuller, S. ). The Chicago style of jazz came about as a result of the migration of jazz artists to Chicago. This type of jazz is known for its soloist performances, relatively more complex and more difficult rhythms. Like the Blues music, the inter-state migration of artists contributed to the spreading of jazz music and its coming to New York made it a huge part of Harlem Renaissance (Morgan, T. and Barlow, W. ). A lot of jazz experimentation happened in New York. These experimentations contributed significantly to the current richness of jazz. The famous piano style, â€Å"jazz stride† was the first piano style to be incorporated into jazz and was very popular in New York. The jazz artist, Fatts Waller is famous for this style. He was also the artist who started the jazz technique, Boogie-Woogie which can be characterized as a combination of different rythms and techniques with a peculiar and repeating bass pattern. Boogie-Woogie later became what is now called Rhythm and Blues (Morgan, T. and Barlow, W. ). James Reese Europe initiated another style of jazz during the era which involved huge orchestras while jazz bands were first put together by Fletcher Henderson. Included in Henderson’s jazz band were Coleman Hawkins, Don Redman and Louis Armstrong. Blues artists often work with jazz bands and individual jazz artists (Morgan, T. and Barlow, W. ; Schuller, S. ). Harlem Renaissance Musicians Louis Armstrong was famous for his technical and yet spontaneous abilities to play jazz. He is considered as among the greatest and influential of all Harlem Renaissance musicians. Unsurprisingly, Armstrong came from New Orleans which is one of the major places that contributed to the development of Harlem Renaissance music. He learned to play cornet while at a reform school when he was twelve and showed his interest in music by staying in blues and jazz clubs. His major influence was Joe â€Å"King† Oliver who became his father figure and mentor. Armstrong soon played for Oliver’s band in Chicago then left for New York to play for Fletcher Henderson’s Orchestra. He also did lots of recordings with other Jazz and Blues artists like Clarence Williams, Red Onion Jazz, Carrol Dickenson and his wife, Lilian (â€Å"Harlem Renaissance†). Duke Ellington is another musical figure in the Harlem Renaissance. He was a composer and pianist and is considered to have brought jazz into concert halls as well as in churches. His style of music can be described as a combination of blues, jazz and swing constructed in solo instrumental performances. He was in New York City during the presented Harlem Renaissance period in 1923. At this time he was able to organize a 10-piece band (â€Å"Harlem Renaissance†). Dizzy Gillespie, was a trumpeter who was able to develop â€Å"Be-bop,† with other famous artists like Charlie Parker, Thelonious Monk and Kenny Clarke. â€Å"Be-bop† was considered as the rebellious and eccentric style of jazz. Gillespie also incorporated Latin and Cuban elements such as calypso, rhumba and tango with jazz. In addition to his contributions to music, Gillespie was also a supporter of equal rights movement (â€Å"Harlem Renaissance†). Other artists during the Harlem Renaissance include Josephine Baker; Bessie Smith, Billie Holiday, and Charlie Parker, among others. Harlem Renaissance was a point in history when African-Americans united to prove the error in stereotyping in terms of intellect and productivity. The developments in music, particularly in Blues and Jazz are certain products of this movement and have given justice to the movement’s objective proving that African-Americans can not only be superior but also developers and re-inventors of what was then just cultural and now all cultural, sensational and global.
