American art forms during the second half(a) of the twentieth nose candy a good deal de o.k.d the styles and qualities that the rest of the world emu juveniled. At the end of the 20th century, American art was considered equal in quality and animation to art produced in the rest of the world. Throughout the 20th century, American arts have grown to incorporate hot visions and voices. Much of this new exquisite energy came in the set off of Americas emergence as a superpower after World War II.But it was also due to the growth of refreshing York metropolis as an important center for publishing and the arts, and the immigration of artists and intellectuals fleeing fascism in Europe before and during the war. An outpouring of talent also followed the civil rights and complain opera ho practice sessiontions of the sixties, as cultural discrimination against blacks, women, and other groups diminished. American arts flourish in many places and receive stand out from private foundations, large corporations, local disposals, national official agencies, museums, galleries, and individuals.What is considered valuable of livelihood often looks on definitions of quality and of what constitutes art. This is a tricky subject when the popular arts are increasingly incorporated into the domain of the fine arts and new forms such as performance art and c at a timeptual art appear. As a result, defining what is art affects what students are taught about past customss (for example, Native American tent paintings, oral customss, and slave narratives) and what is produced in the future.While many practitioners, such as studio artists, are more vulnerable to these definitions be author they depend on fiscal support to exercise their talents, others, such as poets and photographers, are less(prenominal) immediately constrained. artistic productionists operate in a world where those who theorize and brushup their work have taken on an increasingly important role. Audiences are influenced by a variety of intermediariescritics, the schools, foundations that offer grants, the matter Endowment for the liberal arts, gallery owners, publishers, and sign manufacturing businesss.In some areas, such as the perform arts, popular audiences may ultimately define succeeder. In other arts, such as painting and sculpture, success is far more dependent on critics and a few, often wealthy, art collectors. Writers depend on publishers and on the public for their success. Unlike their predecessors, who relied on formal criteria and ap pealed to esthetic judgments, critics at the end of the 20th century leaned more toward popular tastes, taking into account groups previously ignored and valuing the merger of popular and elite forms.These critics often relied less on esthetic judgments than on social measures and were eager to place exquisite productions in the context of the time and social conditions in which they were created. Whereas earlier critics attempted to create an American tradition of high art, later critics apply art as a means to give power and approval to nonelite groups who were previously non considered worthy of including in the nations artistic heritage. Not so long ago, culture and the arts were assumed to be an unalterable inheritancethe accumulated wisdom and highest forms of movement that were naturalized in the past.In the 20th century largely, and certainly since World War II, artists have been boldly destroying older traditions in sculpture, painting, dance, music, and literature. T he arts have changed rapidly, with one movement replacing another in quick succession. a) Visual arts. The visual arts have traditionally included forms of expression that appeal to the eyes by means of calico surfaces, and to the sense of space by dint of carved or molded materials. In the nineteenth century, photographs were added to the paintings, drawings, and sculpture that make up the visual arts.The visual arts were only augmented in the 20th century by the accompaniment of other materials, such as found objects. These changes were accompanied by a in unadorned novelty in tastes, as earlier emphasis on realistic representation of people, objects, and landscapes made way for a greater range of imaginative forms. During the late 19th and early 20th centuries, American art was considered inferior to European art. Despite noted American painters such as Thomas Eakins, Winslow Homer, Mary Cassatt, and washbowl Marin, American visual arts barely had an international presen ce.American art began to flourish during the Great natural depression of the 1930s as new born(p) Deal government programs provided support to artists along with other sectors of the population. Artists affiliated with each other and certain a sense of common purpose through programs of the Public Works Administration, such as the Federal Art Project, as surface as programs sponsored by the Treasury Department. Most of the art of the period, including painting, photography, and mural work, foc apply on the plight of the American people during the depression, and more or less artists painted real people in difficult circumstances.Artists such as Thomas Hart Benton and Ben Shahn expressed the suffering of ordinary people through their representations of struggling farmers and workers. While artists such as Benton and Grant Wood focused on rural feel, many painters of the 1930s and 1940s depicted the multicultural life of the American city. Jacob Lawrence, for example, re-create d the history and lives of African Americans. Other artists, such as Andrew Wyeth and Edward Hopper, tried to use human figures to describe emotional states such as solitariness and despair. Abstract Expressionism.Shortly after World War II, American art began to garner worldwide circumspection and admiration. This change was due to the innovative excitement of nip expressionism in the 1950s and to subsequent groundbreaking art movements and artists. The come up expressionists of the mid-20th century bust from the realist and figurative tradition set in the 1930s. They emphasised their radio link to international artistic visions rather than the particularities of people and place, and about abstract expressionists did not paint human figures (although artist Willem de Kooning did portrayals of women).Color, shape, and movement dominated the canvases of abstract expressionists. Some artists broke with the Western art tradition by adopting innovative painting stylesduring th e 1950s Jackson Pollock painted by dripping paint on canvases without the use of brushes, temporary hookup the paintings of Mark Rothko often consisted of large patches of color that seem to vibrate. Abstract expressionists entangle alienated from their surrounding culture and used art to challenge orderings conventions. The work of each artist was quite individual and distinctive, but all the artists identified with the radicalism of artistic creativity.The artists were eager to challenge conventions and limits on expression in assure to redefine the nature of art. Their radicalism came from liberating themselves from the confining artistic traditions of the past. The to the highest degree notable activity took place in raw(a) York metropolis, which became one of the worlds most important art centers during the second half of the 20th century. The radical fervor and inventiveness of the abstract expressionists, their frequent association with each other in juvenile York City s Greenwich Village, and the support of a group of gallery owners and dealers turned them into an artistic movement.Also know as the New York School, the participants included Barnett Newman, Robert Motherwell, Franz Kline, and Arshile Gorky, in addition to Rothko and Pollock. The members of the New York School came from diverse backgrounds such as the American Midwest and Northwest, Armenia, and Russia, bringing an international flavor to the group and its artistic visions. They hoped to appeal to art audiences everywhere, regardless of culture, and they felt connected to the radical innovations introduced earlier in the 20th century by European artists such as Pablo Picasso and Marcel Duchamp.Some of the artistsHans Hofmann, Gorky, Rothko, and de Kooningwere not born in the United States, but all the artists saw themselves as part of an international creative movement and an aesthetic rebellion. As artists felt released from the boundaries and conventions of the past and plain t o emphasize communicativeness and innovation, the abstract expressionists gave way to other innovative styles in American art. Beginning in the 1930s Joseph Cornell created hundreds of boxed assemblages, usually from found objects, with each base on a single theme to create a mood of contemplation and sometimes of reverence.Cornells boxes exemplify the new-fangled fascination with individual vision, art that breaks down boundaries in the midst of forms such as painting and sculpture, and the use of passing(a) objects toward a new end. Other artists, such as Robert Rauschenberg, combined disparate objects to create large, collage-like sculptures known as combines in the 1950s. Jasper Johns, a painter, sculptor, and printmaker, recreated countless familiar objects, most memorably the American flag. The most prominent American artistic style to follow abstract expressionism was the pop art movement that began in the 1950s.Pop art attempted to connect traditional art and popular cu lture by using images from smokestack culture. To stir up viewing audience out of their preconceived notions about art, sculptor Claes Oldenburg used everyday objects such as pillows and beds to create witty, soft sculptures. Roy Lichtenstein took this a step yet by elevating the techniques of commercial art, notably cartooning, into fine art worthy of galleries and museums. Lichtensteins large, blown-up cartoons fill the surface of his canvases with grainy black dots and question the existence of a distinct land of high art.These artists tried to make their audiences see ordinary objects in a refreshing new way, thereby breaking down the conventions that formerly outlined what was worthy of artistic representation. Probably the best-known pop artist, and a leader in the movement, was Andy Warhol, whose images of a Campbells soup can and of the actress Marilyn Monroe explicitly eroded the boundaries in the midst of the art world and mass culture. Warhol also cultivated his sta tus as a celebrity. He worked in film as a director and manufacturing business to break down the boundaries between traditional and popular art.Unlike the abstract expressionists, whose modelual works were often difficult to understand, Andy Warhols pictures, and his own face, were hourly recognizable. Conceptual art, as it came to be known in the mid-sixties, like its predecessors, sought to break free of traditional artistic associations. In conceptual art, as practiced by Sol LeWitt and Joseph Kosuth, concept takes precedent over actual object, by stimulating thought rather than following an art tradition based on conventional standards of beauty and artisanship. mod artists changed the meaning of traditional visual arts and brought a new imaginative dimension to ordinary experience. Art was no longer viewed as separate and distinct, housed in museums as part of a historical inheritance, but as a continuous creative process. This emphasis on constant change, as well as on the o rdinary and mundane, reflected a distinctly American democratizing perspective. Viewing art in this way removed the emphasis from technique and polished performance, and many modern artworks and experiences became more about expressing ideas than about perfecting finished products. Photography.Photography is probably the most democratic modern art form because it can be, and is, practiced by most Americans. Since 1888, when George Eastman developed the Kodak camera that allowed anyone to take pictures, photography has struggled to be recognized as a fine art form. In the early part of the 20th century, photographer, editor, and artistic impresario Alfred Stieglitz open 291, a gallery in New York City, with fellow photographer Edward Steichen, to showcase the works of photographers and painters. They also published a magazine called television camera Work to outgrowth awareness about photographic art.In the United States, photographic art had to compete with the widely available c ommercial photography in news and fashion magazines. By the 1950s the tradition of photojournalism, which presented news stories primarily with photographs, had produced many outstanding works. In 1955 Steichen, who was director of photography at the Museum of incumbent Art in New York, called attention to this work in an exhibition called The Family of Man. Throughout the 20th century, most professional photographers earned their living as portraitists or photojournalists, not as artists.One of the most important exceptions was Ansel Adams, who took majestic photographs of the Western American landscape. Adams used his art to stimulate social awareness and to support the conservation cause of the Sierra Club. He helped found the photography surgical incision at the Museum of Modern Art in 1940, and six years later helped establish the photography plane section at the California School of Fine Arts in San Francisco (now the San Francisco Art Institute). He also held annual photog raphy workshops at Yosemite National Park from 1955 to 1981 and wrote a series of influential books on photographic technique.Adamss elegant landscape photography was only one small stream in a growing accredited of interest in photography as an art form. Early in the 20th century, teacher-turned-photographer Lewis Hine established a documentary tradition in photography by capturing actual people, places, and events. Hine photographed urban conditions and workers, including child laborers. Along with their artistic value, the photographs often implicitly called for social reform. In the 1930s and 1940s, photographers joined with other depression-era artists supported by the federal government to create a hotographic record of rural America. Walker Evans, Dorothea Lange, and Arthur Rothstein, among others, produced memorable and widely reproduced portraits of rural poverty and American distress during the Great Depression and during the pitter-patter storms of the period. In 1959, after touring the United States for two years, Swiss-born photographer Robert Frank published The Americans, one of the landmarks of documentary photography. His photographs of everyday life in America introduced viewers to a depressing, and often depressed, America that existed in the midst of prosperity and world power.Photographers act to search for new photographic viewpoints. This search was perhaps most disturbingly bodily in the work of Diane Arbus. Her photos of mental patients and her surreal depictions of Americans altered the viewers relationship to the photograph. Arbus emphasized artistic alienation and forced viewers to gaze at images that often made them uncomfortable, thus changing the meaning of the ordinary reality that photographs are meant to capture. American photography continues to flourish.The many variants of art photography and socially cognizant documentary photography are widely available in galleries, books, and magazines. A host of other visual arts thrive, although they are far less connected to traditional fine arts than photography. Decorative arts include, but are not limited to, art glass, furniture, jewelry, pottery, metalwork, and quilts. Often exhibited in craft galleries and studios, these nonfunctional arts rely on ideals of beauty in shape and color as well as an appreciation of well-executed crafts. Some of these forms are also developed commercially.The cosmetic arts provide a wide range of opportunity for creative expression and have become a means for Americans to actively infix in art and to purchase art for their homes that is more affordable than works produced by many contemporary fine artists. 4. Performing arts As in other cultural spheres, the performing arts in the United States in the 20th century increasingly blended traditional and popular art forms. The unspotted performing artsmusic, opera, dance, and field of battlewere not a widespread feature of American culture in the first off half of the 2 0th century.These arts were generally import from or strongly influenced by Europe and were mainly appreciated by the wealthy and well educated. Traditional art usually referred to classical forms in ballet and opera, orchestral or chamber music, and serious drama. The distinctions between traditional music and popular music were firmly drawn in most areas. During the 20th century, the American performing arts began to incorporate wider groups of people. The African American community produced great musicians who became widely known around the country.Jazz and blues singers such as Bessie Smith, Louis Armstrong, Duke Ellington, and Billie holiday spread their sounds to black and white audiences. In the 1930s and 1940s, the swing music of Benny Goodman, Tommy Dorsey, and Glenn Miller adapted jazz to make a funny American music that was popular around the country. The American performing arts also blended Latin American influences beginning in the 20th century. mingled with 1900 a nd 1940, Latin American dances, such as the tango from Argentina and the rumba from Cuba, were introduced into the United States.In the 1940s a fusion of Latin and jazz elements was turned on(p) first by the Afro-Cuban mambo and later on by the Brazilian bossa nova. Throughout the 20th century, dynamic classical institutions in the United States attracted international talent. Noted Russian-born choreographer George Balanchine established the pass(a) American concert dance Company in the 1930s later he founded the company that in the 1940s would become the New York City Ballet. The American Ballet Theatre, also established during the 1940s, brought in non-American dancers as well.By the 1970s this company had attracted Soviet defector Mikhail Baryshnikov, an internationally acclaimed dancer who served as the companys artistic director during the 1980s. In classical music, influential Russian composer Igor Stravinsky, who composed symphonies using innovative melodic styles, moved to the United States in 1939. German-born pianist, composer, and theatre director Andre Previn, who started out as a jazz pianist in the 1940s, went on to conduct a progeny of distinguished American symphony orchestras.Another Soviet, cellist Mstislav Rostropovich, became conductor of the National Symphony Orchestra in capital of the United States, D. C. , in 1977. Some of the most innovative artists in the first half of the 20th century successfully incorporated new forms into classical traditions. Composers George Gershwin and Aaron Copland, and dancer Isadora Duncan were notable examples. Gershwin combined jazz and spiritual music with classical in popular works such as Rhapsody in blue angel (1924) and the opera Porgy and Bess (1935).Copland developed a unique style that was influenced by jazz and American folk music. Early in the century, Duncan redefined dance along more expressive and free-form lines. Some artists in music and dance, such as composer John Cage and dancer an d choreographer Merce Cunningham, were even more data-based. During the 1930s Cage worked with electronically produced sounds and sounds made with everyday objects such as pots and pans. He even invented a new kind of piano.During the late 1930s, avant-garde choreographer Cunningham began to collaborate with Cage on a number of projects. by chance the greatest, and certainly the most popular, American innovation was the Broadway musical, which also became a movie staple. Beginning in the 1920s, the Broadway musical combined music, dance, and dramatic performance in ways that surpassed the older vaudeville shows and musical revues but without being as complex as European grand opera.By the 1960s, this American musical tradition was well established and had produced extraordinary works by important musicians and lyricists such as George and Ira Gershwin, Irving Berlin, Cole Porter, Richard Rodgers, Lorenz Hart, Jerome Kern, and Oscar Hammerstein II. These productions required an imme nse effort to coordinate music, drama, and dance. Because of this, the musical became the brooder of an American modern dance tradition that produced some of Americas greatest choreographers, among them Jerome Robbins, Gene Kelly, and Bob Fosse.In the 1940s and 1950s the American musical tradition was so dynamic that it attracted outstanding classically trained musicians such as Leonard Bernstein. Bernstein composed the music for West Side Story, an updated version of Romeo and Juliet set in New York that became an instant classic in 1957. The following year, Bernstein became the first American-born conductor to lead a major American orchestra, the New York Philharmonic. He was an international sensation who travelled the world as an ambassador of the American style of conducting.He brought the art of classical music to the public, especially through his Young Peoples Concerts, television shows that were seen around the world. Bernstein used the many facets of the musical tradition as a force for change in the music world and as a way of bringing attention to American innovation. In many ways, Bernstein embodied a transformation of American music that began in the 1960s. The changes that took place during the 1960s and 1970s resulted from a significant increase in funding for the arts and their increased availability to larger audiences.New York City, the American center for art performances, experienced an artistic explosion in the 1960s and 1970s. data-based off-Broadway theaters open up, new ballet companies were established that often emphasized modern forms or blended modern with classical (Martha Graham was an especially important influence), and an experimental music scene developed that included composers such as Philip Glass and performance groups such as the Guarneri String Quartet. Dramatic innovation also continued to aggrandize with the works of playwrights such as Edward Albee, Tony Kushner, and David Mamet.As the variety of performances spre ad out, so did the serious cross between traditional and popular music forms. Throughout the 1960s and 1970s, an expanded repertoire of traditional arts was being conveyed to new audiences. Popular music and jazz could be heard in formal settings such as Carnegie Hall, which had once been restricted to classical music, while the Brooklyn Academy of Music became a venue for experimental music, exotic and ethnic dance presentations, and traditional productions of grand opera. advance(a) producer Joseph Papp had been staging Shakespeare in Central Park since the 1950s.capital of Massachusetts conductor Arthur Fiedler was playing a mixed repertoire of classical and popular favorites to large audiences, often outdoors, with the Boston Pops Orchestra. By the mid-1970s the United States had several world-class symphony orchestras, including those in Chicago New York Cleveland, Ohio and Philadelphia, Pennsylvania. Even grand opera was affected. Once a vary taste that often required exten sive knowledge, opera in the United States increased in popularity as the roster of respected institutions grew to include companies in Seattle, Washington Houston, Texas and Santa Fe, New Mexico.American composers such as John Adams and Philip Glass began composing modern operas in a new minimalist style during the 1970s and 1980s. The crossover in tastes also influenced the Broadway musical, probably Americas most durable music form. Starting in the 1960s, rock music became an ingredient in musical productions such as tomentum (1967). By the 1990s, it had become an even stronger presence in musicals such as Bring in Da Noise, Bring in Da backfire (1996), which used African American music and dance traditions, and Rent (1996) a modern, rock version of the classic opera La Boheme.This updating of the musical opened the theater to new ethnic audiences who had not previously attended Broadway shows, as well as to young audiences who had been raised on rock music. Performances of all kinds have become more available across the country. This is due to both the sheer increase in the number of performance groups as well as to advances in transportation. In the last quarter of the 20th century, the number of major American symphonies doubled, the number of resident theaters increased fourfold, and the number of dance companies increased tenfold.At the corresponding time, planes made it easier for artists to travel. Artists and companies regularly tour, and they expand the audiences for individual artists such as performance artist Laurie Anderson and opera singer Jessye Norman, for musical groups such as the Juilliard Quartet, and for dance troupes such as the Alvin Ailey American Dance Theater. Full-scale theater productions and musicals first presented on Broadway now reach cities across the country. The United States, once a provincial outpost with a limited European tradition in performance, has become a flourishing center for the performing arts. . Arts and letters The arts, more than other features of culture, provide avenues for the expression of imagination and personal vision. They offer a range of emotional and intellectual pleasures to consumers of art and are an important way in which a culture represents itself. There has long been a Western tradition distinguishing those arts that appeal to the multitude, such as popular music, from thosesuch as classical orchestral musicnormally available to the elite of learning and taste. Popular art forms are usually seen as more representative American products.In the United States in the recent past, there has been a blending of popular and elite art forms, as all the arts experienced a period of remarkable cross-fertilization. Because popular art forms are so widely distributed, arts of all kinds have prospered. The arts in the United States express the many faces and the enormous creative range of the American people. Especially since World War II, American innovations and the immense energy displayed in literature, dance, and music have made American cultural works world famous.Arts in the United States have become internationally prominent in ways that are unparalleled in history. American art forms during the second half of the 20th century often defined the styles and qualities that the rest of the world emulated. At the end of the 20th century, American art was considered equal in quality and vitality to art produced in the rest of the world. Throughout the 20th century, American arts have grown to incorporate new visions and voices. Much of this new artistic energy came in the wake of Americas emergence as a superpower after World War II.But it was also due to the growth of New York City as an important center for publishing and the arts, and the immigration of artists and intellectuals fleeing fascism in Europe before and during the war. An outpouring of talent also followed the civil rights and protest movements of the 1960s, as cultural discrimination ag ainst blacks, women, and other groups diminished. American arts flourish in many places and receive support from private foundations, large corporations, local governments, federal agencies, museums, galleries, and individuals.What is considered worthy of support often depends on definitions of quality and of what constitutes art. This is a tricky subject when the popular arts are increasingly incorporated into the domain of the fine arts and new forms such as performance art and conceptual art appear. As a result, defining what is art affects what students are taught about past traditions (for example, Native American tent paintings, oral traditions, and slave narratives) and what is produced in the future.While some practitioners, such as studio artists, are more vulnerable to these definitions because they depend on financial support to exercise their talents, others, such as poets and photographers, are less immediately constrained. Artists operate in a world where those who the orize and critique their work have taken on an increasingly important role. Audiences are influenced by a variety of intermediariescritics, the schools, foundations that offer grants, the National Endowment for the Arts, gallery owners, publishers, and theater producers.In some areas, such as the performing arts, popular audiences may ultimately define success. In other arts, such as painting and sculpture, success is far more dependent on critics and a few, often wealthy, art collectors. Writers depend on publishers and on the public for their success. Unlike their predecessors, who relied on formal criteria and appealed to aesthetic judgments, critics at the end of the 20th century leaned more toward popular tastes, taking into account groups previously ignored and valuing the merger of popular and elite forms.

By the 1950s the tradition of photojournalism, which presented news stories primarily with photographs, had produced many outstanding works. In 1955 Steichen, who was director of photography at the Museum of Modern Art in New York, called attention to this work in an exhibition called The Family of Man.Throughout the 20th century, most professional photographers earned their living as portraitists or photojournalists, not as artists. One of the most important exceptions was Ansel Adams, who took majestic photographs of the Wester n American landscape. Adams used his art to stimulate social awareness and to support the conservation cause of the Sierra Club. He helped found the photography department at the Museum of Modern Art in 1940, and six years later helped establish the photography department at the California School of Fine Arts in San Francisco (now the San Francisco Art Institute).He also held annual photography workshops at Yosemite National Park from 1955 to 1981 and wrote a series of influential books on photographic technique. Adamss elegant landscape photography was only one small stream in a growing current of interest in photography as an art form. Early in the 20th century, teacher-turned-photographer Lewis Hine established a documentary tradition in photography by capturing actual people, places, and events. Hine photographed urban conditions and workers, including child laborers.Along with their artistic value, the photographs often implicitly called for social reform. In the 1930s and 1940 s, photographers joined with other depression-era artists supported by the federal government to create a photographic record of rural America. Walker Evans, Dorothea Lange, and Arthur Rothstein, among others, produced memorable and widely reproduced portraits of rural poverty and American distress during the Great Depression and during the dust storms of the period.In 1959, after touring the United States for two years, Swiss-born photographer Robert Frank published The Americans, one of the landmarks of documentary photography. His photographs of everyday life in America introduced viewers to a depressing, and often depressed, America that existed in the midst of prosperity and world power. Photographers continued to search for new photographic viewpoints. This search was perhaps most disturbingly embodied in the work of Diane Arbus. Her photos of mental patients and her surreal depictions of Americans altered the viewers relationship to the photograph.Arbus emphasized artistic al ienation and forced viewers to stare at images that often made them uncomfortable, thus changing the meaning of the ordinary reality that photographs are meant to capture. American photography continues to flourish. The many variants of art photography and socially conscious documentary photography are widely available in galleries, books, and magazines. A host of other visual arts thrive, although they are far less connected to traditional fine arts than photography.Decorative arts include, but are not limited to, art glass, furniture, jewelry, pottery, metalwork, and quilts. Often exhibited in craft galleries and studios, these decorative arts rely on ideals of beauty in shape and color as well as an appreciation of well-executed crafts. Some of these forms are also developed commercially. The decorative arts provide a wide range of opportunity for creative expression and have become a means for Americans to actively participate in art and to purchase art for their homes that is m ore affordable than works produced by many contemporary fine artists. . Performing arts As in other cultural spheres, the performing arts in the United States in the 20th century increasingly blended traditional and popular art forms. The classical performing artsmusic, opera, dance, and theaterwere not a widespread feature of American culture in the first half of the 20th century. These arts were generally imported from or strongly influenced by Europe and were mainly appreciated by the wealthy and well educated. Traditional art usually referred to classical forms in ballet and opera, orchestral or chamber music, and serious drama.The distinctions between traditional music and popular music were firmly drawn in most areas. During the 20th century, the American performing arts began to incorporate wider groups of people. The African American community produced great musicians who became widely known around the country. Jazz and blues singers such as Bessie Smith, Louis Armstrong, Du ke Ellington, and Billie Holiday spread their sounds to black and white audiences. In the 1930s and 1940s, the swing music of Benny Goodman, Tommy Dorsey, and Glenn Miller adapted jazz to make a unique American music that was popular around the country.The American performing arts also blended Latin American influences beginning in the 20th century. Between 1900 and 1940, Latin American dances, such as the tango from Argentina and the rumba from Cuba, were introduced into the United States. In the 1940s a fusion of Latin and jazz elements was stimulated first by the Afro-Cuban mambo and later on by the Brazilian bossa nova. Throughout the 20th century, dynamic classical institutions in the United States attracted international talent.Noted Russian-born choreographer George Balanchine established the short-lived American Ballet Company in the 1930s later he founded the company that in the 1940s would become the New York City Ballet. The American Ballet Theatre, also established durin g the 1940s, brought in non-American dancers as well. By the 1970s this company had attracted Soviet defector Mikhail Baryshnikov, an internationally acclaimed dancer who served as the companys artistic director during the 1980s. In classical music, influential Russian composer Igor Stravinsky, who composed symphonies using innovative musical styles, moved to the United States in 1939.German-born pianist, composer, and conductor Andre Previn, who started out as a jazz pianist in the 1940s, went on to conduct a number of distinguished American symphony orchestras. Another Soviet, cellist Mstislav Rostropovich, became conductor of the National Symphony Orchestra in Washington, D. C. , in 1977. Some of the most innovative artists in the first half of the 20th century successfully incorporated new forms into classical traditions. Composers George Gershwin and Aaron Copland, and dancer Isadora Duncan were notable examples.Gershwin combined jazz and spiritual music with classical in popul ar works such as Rhapsody in Blue (1924) and the opera Porgy and Bess (1935). Copland developed a unique style that was influenced by jazz and American folk music. Early in the century, Duncan redefined dance along more expressive and free-form lines. Some artists in music and dance, such as composer John Cage and dancer and choreographer Merce Cunningham, were even more experimental. During the 1930s Cage worked with electronically produced sounds and sounds made with everyday objects such as pots and pans.He even invented a new kind of piano. During the late 1930s, avant-garde choreographer Cunningham began to collaborate with Cage on a number of projects. Perhaps the greatest, and certainly the most popular, American innovation was the Broadway musical, which also became a movie staple. Beginning in the 1920s, the Broadway musical combined music, dance, and dramatic performance in ways that surpassed the older vaudeville shows and musical revues but without being as complex as Eu ropean grand opera.By the 1960s, this American musical tradition was well established and had produced extraordinary works by important musicians and lyricists such as George and Ira Gershwin, Irving Berlin, Cole Porter, Richard Rodgers, Lorenz Hart, Jerome Kern, and Oscar Hammerstein II. These productions required an immense effort to coordinate music, drama, and dance. Because of this, the musical became the incubator of an American modern dance tradition that produced some of Americas greatest choreographers, among them Jerome Robbins, Gene Kelly, and Bob Fosse.In the 1940s and 1950s the American musical tradition was so dynamic that it attracted outstanding classically trained musicians such as Leonard Bernstein. Bernstein composed the music for West Side Story, an updated version of Romeo and Juliet set in New York that became an instant classic in 1957. The following year, Bernstein became the first American-born conductor to lead a major American orchestra, the New York Philh armonic. He was an international sensation who traveled the world as an ambassador of the American style of conducting.He brought the art of classical music to the public, especially through his Young Peoples Concerts, television shows that were seen around the world. Bernstein used the many facets of the musical tradition as a force for change in the music world and as a way of bringing attention to American innovation. In many ways, Bernstein embodied a transformation of American music that began in the 1960s. The changes that took place during the 1960s and 1970s resulted from a significant increase in funding for the arts and their increased availability to larger audiences.New York City, the American center for art performances, experienced an artistic explosion in the 1960s and 1970s. Experimental off-Broadway theaters opened, new ballet companies were established that often emphasized modern forms or blended modern with classical (Martha Graham was an especially important inf luence), and an experimental music scene developed that included composers such as Philip Glass and performance groups such as the Guarneri String Quartet. Dramatic innovation also continued to expand with the works of playwrights such as Edward Albee, Tony Kushner, and David Mamet.As the variety of performances expanded, so did the serious crossover between traditional and popular music forms. Throughout the 1960s and 1970s, an expanded repertoire of traditional arts was being conveyed to new audiences. Popular music and jazz could be heard in formal settings such as Carnegie Hall, which had once been restricted to classical music, while the Brooklyn Academy of Music became a venue for experimental music, exotic and ethnic dance presentations, and traditional productions of grand opera. Innovative producer Joseph Papp had been staging Shakespeare in Central Park since the 1950s.Boston conductor Arthur Fiedler was playing a mixed repertoire of classical and popular favorites to larg e audiences, often outdoors, with the Boston Pops Orchestra. By the mid-1970s the United States had several world-class symphony orchestras, including those in Chicago New York Cleveland, Ohio and Philadelphia, Pennsylvania. Even grand opera was affected. Once a specialized taste that often required extensive knowledge, opera in the United States increased in popularity as the roster of respected institutions grew to include companies in Seattle, Washington Houston, Texas and Santa Fe, New Mexico.American composers such as John Adams and Philip Glass began composing modern operas in a new minimalist style during the 1970s and 1980s. The crossover in tastes also influenced the Broadway musical, probably Americas most durable music form. Starting in the 1960s, rock music became an ingredient in musical productions such as Hair (1967). By the 1990s, it had become an even stronger presence in musicals such as Bring in Da Noise, Bring in Da Funk (1996), which used African American music and dance traditions, and Rent (1996) a modern, rock version of the classic opera La Boheme.This updating of the musical opened the theater to new ethnic audiences who had not previously attended Broadway shows, as well as to young audiences who had been raised on rock music. Performances of all kinds have become more available across the country. This is due to both the sheer increase in the number of performance groups as well as to advances in transportation. In the last quarter of the 20th century, the number of major American symphonies doubled, the number of resident theaters increased fourfold, and the number of dance companies increased tenfold.At the same time, planes made it easier for artists to travel. Artists and companies regularly tour, and they expand the audiences for individual artists such as performance artist Laurie Anderson and opera singer Jessye Norman, for musical groups such as the Juilliard Quartet, and for dance troupes such as the Alvin Ailey American Da nce Theater. Full-scale theater productions and musicals first presented on Broadway now reach cities across the country. The United States, once a provincial outpost with a limited European tradition in performance, has become a flourishing center for the performing arts.

Purchasing And Storage Department Commerce Essay

Purchasing And Storage Department Commerce EssayPurchasingrefers to a business or organization attempting to getting goods or services to accomplish the goals of its enterprise. Though there be several organizations that attempt to set standards in the purchasing care for, processes send a fashion vary greatly amidstorganizations. Typic exclusivelyy the word purchasing is not used interchangeably with the word procurement, since procurement typic on the wholey includesExpediting, Supplier Quality, and Traffic and Logistics (TL) in addition to Purchasing.What is storing?Basically, storing is when staying in a hotel during vacation, its likely youll affirm some valuable items and documents on hand like jewelry or passports. Its important to have a safe seat to line these items when staying overnight at a hotel, and understanding the different types of storage options different hotels are likely to offer volition jockstrap you decide how to store your valuables.In Restaurant se ctor, storing refers to preserving and keeping source of food and beverages in order to use them when needed.PURCHASINGSimplifying secureWhile technology is enabling all segments related to secure to appear on a common platform, there are a few issues where technology fails to offer any solution, thereby calling the need for clementintervention with sound judgment.While operating a hotel is supposed to be a difficult task, managing the entire procurement process (for such a unit) is evening much so. The purchase discussion section handles the task of procurement yet all departmentsplaya crucial role in it. That said technology ensures that inter-departmental activities takes place flawlessly. Although purchase has now become dependent on technology for managing inventories and order status, it was originally a manual job. From selection of returns to deciding on a vendor, this department rests on the human ability of judgment. However technology is now making the processes r elated to other departments easier by streamlining all activities.Bulk buyingPurchase is virtually procuring products in large quantities for the stores catering to discordant department needs. In this, various operational tools bridge the relationship betwixt the purchase department and stores, fulfilling the requisites of all departments.If we identify back to earlier times, the process of procuring was d matchless manually where storekeepers would spend time contacting suppliers and then placing the orders after checking and re-checking the inventories placed by various departments for duplication of orders and so on. in that respect existed a Bin card system that took stock manually and preparing all the relevant reports done various stock registers, etc. mouse hare adds, Today, technology is dowry us to indent, maintain, analyze and control the total inventory with greater ease and accuracy. The systems are smart as rise up as user-friendly to provide you the alerts and antecedent intimation about the PAR stock and expiry date, etc.Simplifying purchase orderTechnology might be one crucial aspect that is racy for procurement today but the genesis of the software systems used for it have been a perfect replica of the tasks earlier make manually i.e. the purchase order. Das simplifies this and says, There are a lot of different aspects which are kept in mind while preparing a purchase order and its frequency. The preparation of the purchase order is proportionately related to the consumption pattern and its requirement.Technology still has some drawbacks in the decision making process. It helps in collating information but that doesnt help in making the final decision. Kailash Bahuguna, purchase manager at The Metropolitan Hotel New Delhi, is of the opinion that technology has not invaded this area of operation totally a lot of tasks are human-driven and would remain so in future as well. The important job of this department would al ports remain the negotiation that we do with vendors, reviewing of issue for purchasing, etc. Technology can only assist, he adds.While the preference for vendors could be gauged with data like withstanding capacity, rate comparison, stipulated delivery time and extended confidence facility, the final decision is made after identifying the suppliers reputation and relationship the hotel shares with it, which are subjective issues and purchase committee makes a final decision. Das says, Frequent food market surveys are conducted by the standing purchase committee to assess the current prevailing rate and subsequently used for fruitful negotiations.Technology runs parallel to all tasks to enable swift decisions thereby assisting the entire process. Vendor and inventory management play an important role in preparing the purchase order by various departments (in terms of substitute and unseasoned vendors depending on the product demand and urgency), which is notified to purchase for requisition. Das says, In hotels, the purchase officer is in close coordination with other department heads for timely procurement, maximum utilization of materials, seasonal variance in material procurement, and combating the non-availability of materials in unprecedented conditions.Challenges to overcomeThe challenges vary from hotel to hotel. The structure though remains the resembling one needs to take various factors into consideration like geographic location, size of the hotel, operation period, etc. During the initial days of operations of a new property, the challenges are distinctively unique identifying the possible consumption and requirement needs meticulous calculation as there are no past records to compute at.A property that is in operation for some years should try and bring all departments (with reference to purchase) on a single platform for serene information flow. Bahuguna says it enables a sound way to justify codification and stacking methods helping in the inventory management.STORINGAny type of foodservice facility begins its food preparation process at theback opening, by receiving and storing the raw materials. Food, beverages, and supplies must all be accounted for and properly stored until theyre needed. There are two basic types of storage dry and refrigerated. dry out storage is for canned goods, paper products, and anything else that doesnt need to be kept cold. Refrigerated storage is for items that must be kept chilled or frozen until used.In this article, youll hornswoggle more about them both and about the types of equipment needed to outfit your receiving and storage areas for efficiency, guard duty, and conservation of space. The list includesScalesPalletsCartsShelvesWell overly explain how refrigeration systems work in refrigerators, coolers, freezers, ice makers, and specialty systems like beer kegs and soft-serve machines, and discuss how to select them for your operation.RECEIVING AND DRY STORAGEYoud be amazed at how many deliveries arrive at the back door or loading dock of the average restaurant in a week. And they all have one thing in common They must all be checked for accuracy by someone on your staff. Many owners and chefs go astep further, personally inspecting the quality of fresh items such as produce and seafood and rejecting on the spot those that do not meet their standards or expectations.Having a well-organized receiving area, setting certain hours for deliveries, and designating employees who are responsible for accepting and storing incoming stock ordain save you time and money. Illustration 10-1 signals some of the smartest outdoor dock area features.Merchandise goes from the dock area into the receiving area, shown in Illustration 10-2. The well-equipped receiving area pull up stakes contain these basic itemsScalesPalletsCarts and trucksShelvesMEASURES TO BE TAKEN CARE OFStorerooms should be well ventilated, free of dampness and free of pests and bugs.Bulk products such as suga r and flour, can be emptied into tightly covered, properly labeled approved containers to prevent outside contaminant. Storage containers must have openings large enough to allow easy cleaning between uses.Food cannot be stored in locker rooms, rest rooms, dressing rooms, garbage rooms, mechanical rooms, under sewer lines that are not shielded to intercept potential drips, under leaking water lines (including leaking automatic fire sprinkler heads) under Lines on which water has condensed, or under open stairwells.Products must be stored on shelves or platforms 6 inches from the floor to ensure adequate cleaning of the storeroom floor.REFRIGERATIONAll food must be labeled and dated. Arrange containers apart from one another in a refrigerator to ensure proper cooling. This allows air to circulate around containers. Cover all food while in storage. showing keeps food from drying out and minimizes the possibility of contamination.In walk-in coolers, store all food on shelves. The fo od should be kept at least 6 inches off of the floor. The floor needs to be swept and mopped.Store poultry and meats on the bottom shelves to prevent meat from leaking onto other foods.Use foods on a first in, first out basis (FIFO). Refrigerated, ready-to-eat, potentially hazardous food prepared and held for more than 24 hours in a facility must be marked with the date of preparation. It must be discarded if not sold or served within ten calendar days.RECEIVING PROCEDURES IN THE RESTAURANTReceiving food and supplies from your vendors requires more than simply taking boxes off a delivery truck. Restaurant owners and managers should have procedures in place for any employee who handles deliveries. Consider these suggestions for ways to manage deliveries and other receiving procedures in your restaurant.VERIFICATIONWhenever a restaurant receives an order, the manager or responsible employee should check in the order, or verify that the correct amount of products were received as well as checking the quality of the incoming product.Follow these stepsVerify the quantityBe sure that every product you ordered is accounted for in the delivery. An easy way to do this is to compare your order guide to your invoice and manually check off all items as you look through the delivery. Be sure that product weights and counts are correct.Ensure qualityBe sure the items are of good quality. All refrigerated or frozen items should arrive at the proper temperature, and products should show no signs or damage. However, for one reason or another, food products may arrive unusable. When product is received in poor condition, such as frowsty or rotten, the manager should refuse the order if possible, and contact the vendor immediately to schedule another delivery.Check the apostrophizeMake sure the total cost on the invoice is correct. The money you spend on food orders and other supplies usually makes up a large part of your restaurant expenses, and recording the suspend amount in your financial records is very important to your overall profits and losses.KEEP TRACK OF ALL PURCHASES documentationing track of all purchase invoices will help you stay organized and aware of your spending. When you receive your order, record the total cost the order invoice on your restaurant profit and loss tilt (PL). You can easily log this data in most accounting software, or in a PL spreadsheet on the backoffice computer. This will also help you calculate your inventory and usage, since you add the newly purchased goods to those you have on hand to determine your total available inventory.Date and Store SuppliesOnce you have checked your food for quality and recorded the cost and inventory amount in your records, you are ready to put away your food and supplies. This should be done immediately to ensure that food remains at safe temperatures and to keep an organized kitchen. For perishable foods, this involves dating and appropriately storing the products on yourrestaura nt storage and shelving units.How to Keep Your Customers HealthyThere are laws and systems that have been established to help ensure that the food served in restaurants is safe. Bacteria grow very easily if given the chance.The local anesthetic Health Department will send out inspectors to make sure that the chefs and servers are following the proper guidelines. Inspectors will issue fines for minor violations and can leave out you down for major violations.Working with Inspectors from The Local Health DepartmentThe Heath Department will work with you to establish the correct systems and practices. The inspectors are often feared and dreaded (as they usually show up unannounced at the worst possible time), but most of the regulations have important ramifications for keeping food clean and safe.A system calledHACCP Hazard Analysis Critical Control Pointconsists of seven important steps to ensure food safety. This system was actually first intentional to maintain food safety for N ASA astronauts so you know this stuff works The three main elements of the system arefood microbiology,quality controland peril assessment.The 7 steps of HACCP are as followsAssess hazards and potential risks.Identify critical control points including cross contamination, cooking, cooling, hygiene. compulsive up procedures to make sure safety is maintained at all critical control points.Monitor critical control points and use the correct signs, tools, and training materials to ensure this.Take corrective actions as soon as a critical control point is in jeopardy or when any violations are pointed out by the Health Department.Set up a record-keeping system to log all of your flowcharts and temperature checksKeep up with the system to make sure it is working.Each food item served in your restaurant will need its own flow chart, which looks at every step of the foods journey from being received into the restaurant from a purveyor to being served to a customer. The steps in between incl ude storage, preparation, holding/display, service, cooling, storage of leftovers and reheating techniques. TheExecutive Chefwill be responsible for these flow charts.Avoiding Food ContaminationThere are many safety procedures to follow when preparing food in your restaurant. One of the most important is to thaw frozen foods properly. You can cook food from its frozen state or by refrigerating it at under 38 degrees F. You may also thaw under running water at a temperature of 70 degrees F. or below for up to two hours. A microwave is another acceptable way to thaw foods, but only if the entire cooking period will be in the microwave or the food will be finished (immediately after microwaving) by another cooking method.Food items such as meats and poultry must be cooked to the correct internal temperatures. Thermometers are the best way to ensure accuracy of these temps.Avoid Cross ContaminationCross contamination is all too common in kitchens today. Be sure to clean and sanitize any equipment used to prepare food between uses and be specially vigilant when handling a potentially harmful food such as raw poultry,beef or fish.There is a danger zone of temperature, 40 degrees F. 140 degrees F., within which food bacteria multiply rapidly and can thrive. The temperature of food should be kept out of this zone as much as possible. The limit for time spent in the danger zone including all aspects of storage, preparation and service is 4 hours.Food StorageStorage is another way to protect your food from becoming contaminated or spoiled. There are designs for this area as well. Use the first in, first out (FIFO in accounting) rule meaning that foods should be used in the order they are delivered. For instance, do not use the newest milk first if you still have two gallons that are good from your last delivery. Date goods and place the new behind the old on your storage shelves.Keep all foods wrapped and clean. Each item in your walk-in refrigerator, freezer and you r dry storage should be in a sealed labeled container or package with the contents and date received. Do not take a chance on questionable foods When in doubt, throw it out is a great rule to live when it comes to food safety. Go through your refrigerator unit regularly and get rid of spoiled foods.The refrigerator temperature must be below 38 degrees F. Items stored include meats, seafood, vegetables and dairy products. Keep a working thermometer in the unit at all times so you will know at a glance if there is a problem. You do not want to lose your entire inventory Freezers should keep foods at below 0 degrees F. Most foods will not maintain their quality in a freezer so it should be used only as needed. Use fresh products whenever possible.Items in dry storage should be kept between 50 70 degrees F with a relative humidity of 50 60%.

Nuclear Power Versus Renewable Energy

Nuclear Power Versus Renewable EnergyOne of the biggest problems that we face in todays modern mogul hungry times is the decision on a individual(a) source of spring. As we continue to consume as a clubho intake we are very quickly burning through our supplies of fossil fuels to the point at which in a couple of decades we leave occupy all scarce exhausted existing supplies.It is for this reason that decisions need to be made on what source get out take future generations electricity. The future of dynamism turnout will lie with the criteria set out by fossil fuel vital force production and how well they fit these criteria. Any new fuel source will move over to be readily available and provide a constant supply of energy it will need to be cheap and safe to piddle the same or fewer emissions than that of fossil fuels, although with todays genuine eco standards the later will probably need to be true.One particular source of energy seems the logical choice for the mai n re ho givement for fossil fuels and that is atomic provide, just how do other to a greater extent renewable sources of energy compare to nuclear power? In 2002 it was reported by an MIT study that nuclear power supplied 17% of the worlds electricity consumption 1 and if this is compared to renewable sources such as wind instrument power, geothermal and biomass generators which accounts for practiced 19% as calculated in 2008 2. The aim of this paper is to compare and contrast the viability of contrary energy sources for the future.What is nuclear power?Nuclear power in its current state is the controlled nuclear fission of radioactive material for the generation of electricity.Nuclear power uses Uranium primarily as a fissible material, the first safety device issues come from obtaining a source of uracil that is viable to use for energy generation. Uranium occurs naturally in a compound ore form, comprised of 99.3% U238 and 0.7% U235 3. Uranium 238 is not a suitable iso tope for fission, infact in its natural ore it prevents the uranium from sustaining any sort of nuclear reaction. This can be explained by the energy of absorbed neutrons in the nuclear material, U235 will undergo fission at all energies of neutrons, but U238 will not. To overcome this problem, uranium ore needs to be enriched with a higher percentage of U235 (usually so that U235 comprises 3% to 5% of the ore 3). The enrichment work out issues safety issues that are not present in other forms of energy production, the process constitutes uranium hexafluoride that is a highly toxic chemical that is difficult to chime in due to its corrosive nature. The main waste product is depleted uranium that the radioactive waste from extracting U235 from natural Uranium ore. in that respect has been much controversy over Depleted uraniums use as a weapon and its difficulty in being stored due to its radioactive nature, current estimates put global stockpiles of depleted uranium at 1.5 m illion tonnes 3.The generation of power from radioactive sources makes use of a compound nuclear reaction. Neutrons are absorbed by enriched uranium, usually a uranium ore composed of mainly U235, which forms an brainsick compound nucleus. A compound nucleus will be inherently unstable and result in the fission of the excited compound nucleus and emission of two new nuclei and neutrons. Figure 1 illustrates a possible nuclear reaction inside a nuclear nuclear nuclear reactorFigure 1- Example of nuclear reaction. n+U235 U*236 Xe139 +Sr95 + 2nAs can be seen from figure 1 the example fission reactions require a single neutron to induce fission of U235 but the final products of the reaction include 2 neutrons which allows the reaction to become self perpetuating, this neutron feeding process is known as a chain reaction. This chain reaction will only occur in enriched uranium.Nuclear power is generated using two different types of reactor that both have their merits and faults with r egard to safetyThe fast reactor is a reactor based on an equal mix of Uranium 235 and 238 that can sustain the chain reaction required to generate energy. Fast neutrons, and then the name, sustain the reaction, in the drive of the fast reactor neutrons interact with U238 whicch forms a nucleaus that does not under go fission but forms plutonium 239 instead. Although Pu 239 is able to undergo fission, it does not do so at the speed required to sustain the chain reaction and infact to the highest degree of it becomes unused waste in the form of spent fuel. The fast reactor is designed to navigate around this by using the fast neutrons to produce more fissile Pu239 than spent Pu239 by not using a moderator to slow neutrons down this reduces the problem of producing lots of unused fuel as waste. Because this type of reactor does not use a moderator to control neutrons and due to the highly fissile material in the reactor core, it does require an efficient cooling system which does in troduce certain safety issues. Fast reactors require a liquid atomic number 11 coolant, chosen due to its highly conductive nature, to remove passion from the core. The use of sodium though has its associated risks because its highly reactive and becomes corrosive when reacting with air which is obviously a problem when surrounding a radioactive core.Thermal reactors use enriched uranium to produce energy instead of an equal mix and the enrichment produces the waste products as discussed earlier. Un similar fast reactors which do not use moderators thermal reactors, and the ones in question use a moderator and coolant. In the case of Pressurised pee reactors and boiling water reactors they both use water as a coolant and moderator due to waters inherent retention that it is a good neutron absorber. The water based thermal reactors are one of the most widely used nuclear reactors due to the availability and safety of the coolant and moderator. There are contamination risks with t he boiling water reactor, as water is pumped through the reactor and boils it will pick up fragments of radioactive contaminants which could be released into the glory via the cooling pillars.For note the worlds largest nuclear power plant uses 7 different boiling water reactors to generate electricity and is capable of generating a total of 8,212MW and a typical fossil fuel turbine is capable of generating 1000MW so a typical fossil fuel plant can be compared to outputting a similar descend of energy to that of a nuclear power plant 3b.Safety of Nuclear PowerWith the explosion of the Chernobyl nuclear power plant and the recent meltdown risks of the Fukushima reactors safety bear upons are always inherent when discussing nuclear power.Meltdowns are often a buzz word when associated with nuclear power plants and is often the biggest safety concern when considering nuclear power, but what exactly is a nuclear meltdown? A nuclear meltdown is not as serious as the word suggests or as the world media have suggested. A meltdown will occur when there is more heat inside the reactor core than that being removed by any coolant mechanism that are put in place. If this does happen then the nuclear fuel will literally melt causing it to melt through the reactor. This will result in damage to the reactor core and a possibility of the fuel escaping the reactor, but nuclear reactors are contained within a containment coordinate that is designed to prevent any radioactive material from contaminating the atmosphere and allowing coolant to be pumped into the structure. This only becomes an issue when the containment structure is damaged as was the case during the Fukushima earthquakes, with the exception of natural disasters modern nuclear power plants are designed with the up most safety in mind and have many different precautions in place to prevent and photograph and risk to the general public.Control rods are one of the best designed safety features within a nuclear reactor, they are designed to avoid any rapid increase in reactor core temperatures. When fuel temperatures rise to a temperature at which coolant will be contaminated and need to be ejected, the control rod safety mechanism kicks in. They are designed to slow the neutron flux with in the reactor, much like the moderator does, and hence slow down the rate of energy generation so that coolant can carry heat away without the risk of contamination. Systems are in place so that this precaution is activated immediately when any reactor threat is detected. This safety measure reduces the risk of any radioactive material being ejected via cooling systems.In fact studies suggest that exposure to radioactive sources due to nuclear power stations and nuclear fuel plants are less than 0.1% of human annual exposure to radiation, this can be seen from figure 1. So although there is a high line up of radioactive contamination the safety mechanism that are in place prevent this risks from occurri ng and keeping exposure down to a minimum.Figure 2- Figures showing annual sources of radiation exposure 4With this in mind although there are insecurity risks when considering nuclear fuel as a replacement for fossil fuels, the number of design features installed to prevent this is more than adequate to ensure the safety of the technology.Proliferation concernsOne concern with Nuclear power is not the safety risks of the power station or the waste they produce but instead that enrichment facilities can produce Uranium that is enriched for use in nuclear weapons. This is much a concern in the matureing world where governments are not as stable and it would not take commodious for a fuel enrichment facility to start producing weapons grade uranium.Renewable energy sourcesSo far we have looked at some of the pros and cons of nuclear power and it seems like a viable alternative to fossil fuels, but technological advances have allowed renewable energy sources to become a viable optio n for industrial production of energy. Renewable sources of energy cant produce energy on the scales that nuclear power plants can but they do not suffer from the contamination complications that nuclear power does.Solar powerSolar power exploits natures biggest source of energy the sun, which outputs a massive 3.841026W 5 of which we receive 1.741017 W or 1.366kW/m2 6. This is a huge amount of energy to exploit and an obvious choice for renewable energy because the sun is expected to remain in the sky for the b rescripting four and a half billion years. This plain perfect candidate for energy production seems relatively unused as solar power accounts for just 0.9% 7 of worlds energy production. One of the main issues with solar technology is the photovoltaic cell, this being the standard solar panel technology, it has a relatively low efficiency and as a result the amount of energy outputted does not represent the full potential from the energy put in, also with the sun being an i ntermittent energy source, the only way photovoltaic cells can produce energy at nights is with the use of large banks of batteries, which are expensive and an environmental hazard.There are seemingly new technologies creeping into the solar market, much simpler than the photovoltaic cell and much more efficient. One such technology is the solar tower. The solar tower uses a large field of heliostats which are mirrors that track the sun to focus the suns light on a single point which is a central tower. The central tower uses the heat supplied to drive a steam turbine capable of generating between 10 and 100 MW (dependant on the number of mirrors), for example the PS10 solar power plant in Spain uses 624 heliostats to generate 11MW and is still being constructed8. This may seem like a small amount of energy but a larger area solar power tower could provide much more energy, by increasing the area of the plant, by increasing the number of heliostats. One such project is presently un der way in the Mojave desert which covers 4000 acres and aims to generate enough electricity to power the city of San Francisco 9. Unlike Photovoltaic cells solar power towers have the capability of producing energy at night. When the suns energy is focused on the central tower some of the heat which is used to drive the turbines is also used to heat salts to molten temperatures in redundant of 200 C, molten salts can keep their temperature very well if insulated properly, and when required can be pumped through the turbine to generate steam to generate electricity 10.Given enough time Solar power could become a replacement for fossil fuel energy production, but in the meantime it suffers from high initial costs, a large carbon footprint and a lack of backing. Currently Spain come ins to be the pioneers of this technology and have already constructed numerous solar power towers including PS10 as discussed earlier.Wind powerOne by-product of the suns energy that has yet to be menti oned is that it supplies energy into the atmosphere causing temperature and instancy differences, this produces a bulk movement of air molecules resulting in the wind. The wind is a much more use energy source compared to solar power, with wind power producing 2.5% of the worlds electricity11.Wind power generates electricity in a very similar manner to a conventional power generator, but instead of using water as a fluid to turn a turbine, the wind is the fluid that turns the turbine. Although there is a significant amount of power available in the wind not all of it can be extracted and a theoretical limit has been calculated for the amount of energy that can be 12. This limit means that 59.3% of energy in the wind can be used for energy generation. In reality much less than this is extracted because wind is not a uniform speciality and as such suffers from intermittence issues similar to solar power, in that wind is not a constantly accessible resource.Hydroelectric PowerOne al ready established form of renewable energy is Hydroelectricity, the generation of energy using the conversion of gravitational potential energy of falling water through a turbine. Its currently the 4th largest form of power generation behind coal, gas and nuclear power producing 20% of the worlds current electricity demands 13. Interestingly though Hydroelectricity has been exploited in the 1st world, with almost all possible sites being developed for hydroelectricity, its only in the developing world where hydroelectricity could be utilized to improve renewable energy generation, this would explain why it is the 4th largest energy provider 13.Unlike wind power and solar power, hydroelectric power does not suffer from intermittency issues. The idea behind a hydroelectric dam is that it uses the water at a higher gravitational potential to fall through a turbine generating electricity. When there is a smaller demand for electricity the flow rate can be reduced and the reservoir can b e used to store excess water, this provides the dam with water on demand, which is a unique feature of hydroelectric power.Three gorges dam in china is a fantastic example of a 21st century hydroelectric plant, for reference it is capable of producing 22500MW 14 this is greater than 100 times the amount of energy produced by a solar power tower, and 5 times more energy than the largest nuclear power stations, so obviously hydroelectric dams are useful and utilizable replacement for fossil fuels.Hydroelectricity does have its environmental faults, and is probably the most hazardous of the renewable power sources. In order to construct a hydroelectric plan a large enough meretriciousness of water is required with a big enough drop for potential energy conversion to warrant building a hydroelectric plant. To do this a river must be dammed which upriver will flood a large area of land, this causes huge amounts of destruction to natural habitats, downriver there is a chance that drinkin g water is contaminated which has obvious human impacts.Conclusion on energy typesWe have discussed the different aspects of nuclear power and many different types of renewable energy sources. It is my opinion that despite certain renewable already being established they have still not reached their potential to replace fossil fuels, oddly with certain intermittent issues and as a result are not ready to replace fossil fuels. On the other hand, while renewable sources develop into a more viable energy source nuclear power is ready to replace fossil fuels in the interim.If we compare energy production it would appear as if hydroelectric dams are the best option, but as discussed all sites in the developed world have been exploited and for comparison nuclear power stations are still being built as many possible sites still exist. Despite its safety issues and the non-renewable nature of nuclear fuel, nuclear power is capable of producing a steady supply of power that will meet demand s upon request. In reality there is no one replacement for fossil fuels, as a society we have created a huge dependence on them and it is going to require a mixture of different power sources in order to develop a secure energy future and as a result our future probably lies with renewable energies and nuclear energies working in lodge with each other.References1.

Issue of Tuberculosis in Australia

Issue of Tuberculosis in AustraliaThe incidence and prevalence of Tuberculosis in Australia and Peru ar of greatly vast differences. This paper will discuss the wrong incidence and prevalence why Tuberculosis remains an issue in Australia and provide rationales for differences in incidences and prevalences taking into consideration the determinants of health.Incidence and prevalence when describing infirmity epidemiology be frequently used terms, often intertwined (Advanced Renal Education Program, 2015). Incidence describes the range of new cases of a disease, generally conveyed as the number of new cases which occur at a given point in time (Advanced Renal Education Program, 2015). The incidence rate is commonly reported as a fraction of a population at seek of developing a disease (ie per 100 000) (World health governing Global Tuberculosis Programme). Whereas prevalence is articulated as a percentage of the number of cases per 100 000 (World Health Organization Global Tub erculosis Programme). Prevalence is the material number of live cases of the disease during a period (Advanced Renal Education Program, 2015). The association between incidence and prevalence depends on the natural history of the disease being reported (Health, 2017).Tuberculosis (TB) is one of the worlds deadliest diseases, with 1/3 of the worlds population infected (Centre for unsoundness Control and Prevention, 2017). TB is an infection caused by the bacteria mycobacterium tebibyte, and usually affects the lungs (Australia, 2017). However, TB may also involve the kidneys, bones, spine and brain (Australia, 2017). TB is usually spread by breathing in the bacteria by and by an untreated person has coughed or sneezed (Australia, 2017). Overcrowding is a defining feature of areas of high TB endemicity (Centre for Disease Control and Prevention, 2017). Ongoing close contact between active cases and susceptible individuals is necessary to maintain endemicity in a population, howev er we will discuss health determinants further into this paper.Australia has maintained a low rate of TB since the mid-1980s, however over the last 20 years TB incidence rates have steadily increased (Teo, Tay, Douglas, Krause, Graham, 2015). Australia has recorded its highest incidence rate since 1985 in 2011 being 6.2 per 100, 000 (Teo et al., 2015). In 2015 Australias TB incidence was 6 per 100, 000 per the World Bank (Trade Economics, 2017). When researching the prevalence of TB in Australia World Health Organisation (WHO) publications noted TB case notifications to the value of 1 254, this being the same rate as per new and relapse cases (World Health Organization, 2015).The incidence of TB in Peru shows a a lot more alarming story. Perus TB cases were last measured in 2015 with an incidence rate of 119 per 100, 000 (World Health Organization, 2015). Research obtained from World Bank stating these incidences were recorded from new pulmonary, maculate positive and extra-pulmo nary tuberculosis cases (Economics, 2017). Prevalence information obtained at this time reads TB notification cases of 30 988 (World Health Organization, 2015). Total new and relapse cases registered were reported to be that of 29 833 (World Health Organization, 2015).With Australias TB incidence rate increasing, the question is why is this an issue now? Research shows that many an(prenominal) of Australias holiday destinations are teeming with TB that is now becoming resistant to drug discussion (Dunlevey, 2015). Holiday makers such as teachers and childcare workers are reported to be travelling to TB hot-spots and many bringing the bacteria to Australian shores (Dunlevey, 2015). Research has also shown that those living in high TB prevalent countries are migrating to Australia ((AMA), 2008). With the increases in immigrants, overcrowding and malnutrition are common risk factors for the spread of TB (Australian Indigenous Health Info Net, 2015). Australias shoreline is another fa ctor for the increase in TB rates with Western Province of Papua New greaseball and Torres Strait Islands having recorded active strains of Multi-drug resistant strains of TB ((AMA), 2008).TB remains to be a social disease that is inextricably conjugate to vicious cycles of scantness (Wingfield et al., 2016). Poverty predisposes individuals to TB and hidden costs associated with even free TB treatment can be catastrophic (Wingfield et al., 2015). Other determinants of health that can predispose populations to incidences of TB may include, but are not limited toIncome and social status research shows that higher income and social status can be linked to better health outcomes.Education measly health can be linked to lower education levels, increasing stress and lowering self-confidence.Physical environs safe water and clean air, along with healthy workplaces and safe housing all contribute to good health outcomes. Generally, those people who are employed are healthier.Social al low networks better health outcomes have been linked with communities with great support from families and friends. Culture and beliefs of family and community can have an overall effect on ones health.Genetics can play a role in determining lifespan, healthiness and the likelihood of developing certain illnesses.Health services access and work of services that prevent and treat diseases influences health.Gender different types of diseases at different ages can affect both men and women.The determinants of health are typically accountable for health inequities and the unfair and avoidable differences in health status as seen between Australia and Peru (Hargreaves et al., 2011). Social disadvantages such as lower educational attainment, job uncertainties, unemployment and poor access to appropriate housing (Hargreaves et al., 2011). Poor access to communications and environmental challenges also impact on health status (Hargreaves et al., 2011). Research has shown that although Per us malnutrition and school memorandum rates have improved, there is still a majority of poor children who temporarily or permanently drop out of school to help support their families (Agency, 2017). Poverty, malnutrition, and hunger is known to increase the susceptibility to infection leading to significant social and economic barriers that delay their contact with health systems in which an appropriate treatment regime can be commenced (Hargreaves et al., 2011). With this research found, the author can not state that Australians are better-off than the Peruvians. Non-indigenous Australians living in Metropolitan areas have significantly greater resources at their disposal, housing and schooling is of higher quality, and health and support systems easily accessible (Australian Institute of Health and Welfare, 2012). However, indigenous Australians and those living in rural and upstage areas of Australia do not have the same access as their city cousins (Australian Institute of Hea lth and Welfare, 2012). The determinants of health therefore impact on the ability to access, resource, and engage health care programs (Australian Institute of Health and Welfare, 2012).As discussed, the incidence and prevalence of Tuberculosis in Australia and Peru have been shown to be of great differences. While this paper discussed the terms incidence and prevalence why Tuberculosis remains an issue in Australia and provided rationales for the differences in incidences and prevalences while taking into consideration the determinants of health.REFERENCE LIST(AMA), A.

Parthenogenesis Essay -- Asexual Reproduction, Honeybees

Parthenogenesis is a natural form of asexual reproduction found close commonly in lower organisms and plants. Sometimes known as virgin birth, parthenogenesis, involves the growth of an individual without fertilization. Discovered in the 18th century by naturalist and philosopher, Charles Bonnet, parthenogenesis is a progressive evolutionary strategy that some organisms have employed to maintain a colony. Just as there atomic number 18 benefits to organisms that practice parthenogenesis, like reproduction without the need of male gametes, there are costs, such as a decrease in genetic variation. In the intricate eusocial fundamental law of honeybees, there are three social classes queen bee, prole bees and drone bees. The queen bee, as the name entails, holds the superior position in the colony. The queen bee lays alone the eggs in the colony, being the only bee with a set of completely developed ovaries and having life-long fertility (Back Yard Beekeepers Association n.d.). A fter only one junction flight were the queen mates with a couple male drone bees, she stores the sperm to later fertilizes some of the eggs. The eggs that get fertilized develop into female worker bees and the eggs that develop without fertilization produce male drone bees. Due to the high maintenance of both the colony and its products, i.e. honey, most of the bees in a stash away are female worker bees. These worker bees carry on a magnitude of different tasks, not including reproduction, which is reserved only for the queen. The male drone bees are reserved for mating with the queen bee. Following copulation, the drone dies because of their barbed sex organ (Back Yard Beekeepers Association n.d.). Scientists have been puzzled at how this multifaceted make-up is maintained bu... ...nd genetic factors play a part in sex-determination (Slobodchikoff and Daly 1971). However in some other hymenopterans, parthenogenesis occurs via thelytoky parthenogenesis. There is a subspecies of honeybee, the blanket bee (Apis mellifera capensis), which is known to exhibit thelytoky, the production of diploid females from unfertilized eggs, eliminating the paternal genome (Heimpel and de Boer 2008). In the case of the Cape bee, the queen bee determines whether the eggs are haploid or diploid (Oldroyd et al. 2008). By thelytoky parthenogenesis, the Cape queen be can produce clones of herself (Oldroyd et al. 2008). Undergoing a different form of parthenogenesis gives Cape bees the advantage of creating males that could mate with other promote (Oldroyd et al. 2008), involving one individual for reproduction, and a decrease in gene loss (Slobodchikoff and Daly 1971).

A Comparison of Two Creation Myths :: Compare Contrast, Creation Stories

Can religions and cultures be anything more than their history? Why do we confirm a concept of history in the first place? Obviously history exists, but like the human ability to conceive of the future, history seems to be a rare phenomenon tied with our ability for language and the telling of stories. Whats even more fascinating is the human ability to make up a history or to tell a story, such as a knowledgeability myth, that seeks to explain something that has not been witnessed by anyone and does not have any usage in finding food or creating shelter. We do not have a physical need to fare how the earth came to be or to know how it is that we came to be here. Still, creation stories exist in almost all human cultures and, amazingly, many share many of the same elements. The question is, why? Is it a affinity that so many of them share the same elements? By looking at a comparison of two creation stories, we should be able to understand the center of these similarities better.Just look at two creation stories side-by-side and you should easily see their similarities. Perhaps the easiest way to do this would be to take one unknown creation story and compare it to one from ones own culture. Below is an example of a Mongolian creation myth Long long ago God descended to earth and made a man and awoman out of clay. Before returning to heaven to get some holy w ingestr with the power to animate anything, he ordered his dog and chuck to protect the clay people from the devil. After God ascendedto heaven, the devil came to harm the people. The dog and thecat protected them, though, thwarting the devils plan. Finally,the devil deceived them by giving a piece of meat to the dog anda bowl of milk to the cat. While the dog ate the flesh and the catlapped the milk, the devil urinated on the people and fled.When God returned with the holy water and discovered whathad happened, he was enraged. Scolding the dog and cat forneglecting their duty, he labored the cat to lick the tomentum cerebri off the bodiesof the people whom the devil had defiled (God created humanswith hair all over their bodies). The cat licked off the hair everywhereexcept their heads, armpits, and crotches, since the former
