Dna Sequencing Essay - 1043 Words

DNA Sequencing: Algorithms that Convert Physical to Digital EFFECTS: DNA sequencing, specifically with small â€Å"nanopore† sequencers, have the potential to advance medicine by increasing scientific knowledge of diseases and improving medical diagnosis in remote areas. The leading sequencer today is the MinION, which is an incredible 10x3x2cm and only requires a USB connection to a computer [5]. The MinION currently can sequence viral and bacterial genomes, but will expand to include full human genomes. The MinION’s size and capabilities allow it to target the microscopic source of ailments outside of the laboratory and in a greatly reduced amount of time. Soon after its deployment in 2014, the MinION was used to sequence a salmonella†¦show more content†¦A 100mV voltage is applied across the protein, which draws the DNA through the pore. When a DNA nucleotide is in the pore, a sensor records the change in current as an event [1]. This change in current is stored in a FAST5 file type, which stores metadata and the events [7]. The FAST5 data files then undergo â€Å"base calling†--correlating one of the four nucleotides in DNA with each event--in Amazon Cloud with a software called Metrichor or with offline open-source software called Nanocall [7]. To reduce error rates, base calling algorithms are based off the Viterbi algorithm, which determines the most probable â€Å"path† based upon surrounding measurements. In the case of base calling, the surrounding 5 or 6 nucleotides are examined, 5 having 1024 combinations and 6 having 4096 combinations [9]. While using 6 nucleotides doubles the analysis time, it improves the accuracy of base calling [5]. After base calling, the all analyzed events are compiled into a single complete sequence. This sequence is then compared to sequences in databases such as What’s in My Pot (WIMP) or 16S, which match the sequenced DNA to a specific species [8]. Because of the high speed of the input and base calling, usually species identification is done in real-time [8]. c.

History of British Theatre Free Essays

The earliest forms of theatre in Britain were the religious ritual performances of the native Britons. The first theatre in Britain that we may recognize as such was that of the Romans. While we know a great deal about the Roman theatre its effect on Britain seems to have been limited – theatres were small and not particularly numerous (and may have been used for sports, gladiatorial contests and other mass spectacle entertainments more than for classical theatre). We will write a custom essay sample on History of British Theatre or any similar topic only for you Order Now The ruins of a Roman Theatre in St. Albans still remain as a tourist attraction in Britain today. After the Roman pull out the chief performances in Britain came from travelling bards, or Scops, who provided entertainment to crowds at feasts, at events, or in nobles’ courts, usually in the form of epic poetry. Caedmon’s Hymn and the saga of Beowulf are two of the very few surviving stories that were performed during that time. Organized theatrical performance would soon supplant the Scops, thanks in large part to the spread of Christianity and the rise of the trade guilds in British towns. In the churches the liturgy was increasingly dramatized throughout the Middle Ages, with the architecture of the Churches themselves being used to great effect, with choirs of â€Å"angels† being flown in from the lofts and other spectacular special effects. Soon plays like â€Å"Everyman† were being written by anonymous priests who recognized the power theatre had to convey the Church’s teachings to the masses. And though the church dramas played an important role in nurturing mediaeval drama (and a very important role in developing the playwriting talents of the clergy) a much more immediate and visceral theatre was being forged outside of the churches in the mediaeval towns, in the form of the Cycle Plays. The Cycle Plays were given at the feast of Corpus Christi, and were performed on wagons that could be pulled to several different stations throughout a town. Over 40 individual plays could make up a cycle, with the shows beginning early in the morning and ending as darkness fell. The plays were anonymously written (probably by clergymen) and were dramatizations of the major events of the Bible. After the Cycle Plays waned in the later Middle Ages the wagon-based performances remained, with troupes of actors travelling from town to town performing in courtyards, taverns and wherever else they could secure a paying audience. These travelling players were likely the first taste of live theatre for a young boy from Stratford-upon-Avon named William Shakespeare. The years between Shakespeare arriving in London up until the closing of the theatres in 1642 can easily be called the Golden Age of British drama, for Shakespeare and his contemporaries composed a body of work during that time unequalled in British (and arguable world) theatrical tradition. The plays of the English Renaissance are unrivalled in their rhetorical might. They are, at their best, compelling stories of individual struggle and grand national narratives. But in 1642 the Puritans banned all theatrical performances in the heat of misguided religious fundamentalism. Until the Restoration in 1660 theatre went underground, performed in secret and devolving into less sophisticated entertainments. There is comparatively little written about the British theatre of the 17th, 18th and early 19th centuries for good reason – next to the Renaissance what came after is of vastly inferior quality, almost always concerned with financial success more than any artistic, aesthetic or literary merit. There are exceptions – Sheridan was a playwright of some note, and John Gay’s The Beggar’s Opera a seminal moment in the birth of British musical theatre. But no one could even come close to rivalling Shakespeare until the last years of the 19th century, with the arrival of the Irish playwright George Bernard Shaw. His plays are too polemical to supplant Shakespeare’s universality, but they did sweep away the centuries of mediocrity moving realism onto the English stage. The rise of Naturalistic drama dove-tailed perfectly with the rise of the director as the creative head of play production. With the passing of The Theatres Act in 1968 British Drama was finally freed from the last shackles of the past, when the powers of the Lord Chamberlain to license all plays was abolished. With the birth of the Royal National Theatre in 1963, the discovery of the remains of Shakespeare’s Globe Theatre, and the widespread embrace of theatre by Britons in the 20th and 21st centuries the conditions are ripe for another Golden Age of British drama in the years to come. The White Bear theatre The White Bear Theatre Club is a fringe theatre venue, established in 1988 in the White Bear pub in Kennington. It is run by Artistic Director Michael Kingsbury. Theatre practitioners who have worked at The White Bear include Joe Penhall, Hugh Allison, Mark Little, Emily Watson, Tamsin Outhwaite, Kwame Kwei-Armah, Vicky Featherstone, Torben Betts, Lucinda Coxon, Adam Spreadbury-Maher (Associate director 2008 – 2009) and Chris Loveless (Associate Director, 2009 – ). It is said to be one of the most interesting fringe theatres due to its small size and the intimacy of the acting space. Previous productions include: Bodyclock (Time Out Critics Choice), Cosi, Dracula (A new musical by Alex Loveless adapted from the original story by Bram Stoker), Life’s A Dream, Feathers, The Return of the Soldier, The Card Index, Spin and I Only Want To Be With You. The theatre has been described by London review magazine Time Out as ‘Fringe Theatre of the first order, The White Bear must be saluted for staging such work’ and Michael Billington from The Guardian was quoted as saying ‘Fringe theatre at his best. ‘ The White Bear has received numerous awards including Time Out Best Fringe Venue, Peter Brook Empty Space Award for Best Up and Coming Venue, Carling London Fringe Awards for Best Actor and Best Production. Southwark Playhouse Southwark Playhouse Theatre Company was founded in 1993 by Juliet Alderdice, Tom Wilson Mehmet Ergen. They identified the need for a high quality accessible theatre which would also act as a major resource for the community. The theatre quickly put down strong roots in Southwark, developing an innovative, free at source, education programme. It has worked closely with teachers, Southwark Borough Council, businesses and government agencies to improve educational achievement and raise aspirations. This programme is in great demand and attracts substantial funding each year. The theatre’s primary objectives are †¢ to produce high quality, cutting edge theatre in both traditional and non-traditional theatre environments †¢ to offer a fully resourced and wholly integrated education and community programme, providing opportunities for people of all ages in Southwark to engage with the borough’s rich heritage and cultural potential to support the work of emerging theatre practitioners and companies by providing a well-equipped venue at an affordable cost, with appropriate resources and guidance †¢ to intertwine the artistic, education and community programmes so that fresh insights and opportunities are offered to broad sectors of users within the Southwark community The Drill Hall With a national a nd international reputation, The Drill Hall is the local theatre and arts centre for Bloomsbury and Fitzrovia in London’s West End. Since 1977, The Drill Hall has produced, developed, nurtured and supported over 10,000 artists and productions. We have toured award-winning shows and events all over the world. Through our highly praised education programme we tackle homophobia and bullying and tour to schools, work with teachers, run youth theatres specifically for LGBT young people and have an artist-development programme. Our community theatre troupe, The Drill Hall Darlings, is now in its fourth year. It always welcomes new members and performs at The Drill Hall throughout the year. We have a wide-ranging workshop programme, a free Sure Start drop-in for local children under five and their families, and a regular programme of shows and storytelling for 7 to 11-year-olds. The Drill Hall is a major hub for the arts and media communities, providing some of the most sought after central London rehearsal facilities and radio and television recording spaces. We also offer low-cost meeting space for local community groups. The Drill Hall is one of The Theatres Trust’s new Ecovenues. Through this prestigious scheme we aim to make The Drill Hall more ‘sustainable’. Alexander Grant It is quite easy to make a case for Alexander Grant’s being the greatest male dancer ever produced by a British company. He was a character dancer of infinite variety: technically strong enough to dance Symphonic Variations in his younger days, but remembered principally for the huge number of roles he created (particularly for Ashton), and for the new life he gave to characters he took over from others. For several years in the 70s, Grant directed the Royal Ballet’s educational group, Ballet for All, and in 1976 he left the company for a seven year stint as director of the National Ballet of Canada. These days he is still occasionally to be seen on stage with ENB, and he also coaches and produces – he was responsible for the recent successful Scottish Ballet revival of Fille. A close friend of Ashton’s, he is still an irreplaceable source of information and advice. But his name conjures up, for those who saw him, spectacular dancing – with no trace of ‘look at me’ – and above all the wonderful range of characters he brought to life before our eyes.

A public life Essay Example For Students

A public life Essay Joseph Papp was the most powerful and  infuential man in the American theatre, dominating his world through the force of his own dazzling paradoxical personality. For him, there was no contradiction in the diverse roles he chose to play. An idealist had to be a pragmatist, for how else would he able to bring his ideals into practice? It was natural that Papp, the preeminent figure in the nonprofit theatre, should become the producer of the longest running Broadway musical of all time. More than anyone, he was the bridge between those two traditionally anthithetical camps, the institutional and the commercial theatre and proved that for continuing coexistence one had to nature the other. Appropriately, Papps funeral was held in one of his theatres. Mournes spoke of him as a friend, father figure, mentor and boss, as a man of principle who never shied from confrontation. After his death, some of the artists who owed their entire careers (or at least the advent of their careers) to him lined up to carp at the fact that he had not given them the theatrical equivalent of academic tenure. Amid all the tributes, there were pockets of criticism, including what may have been the first instance of a paid obituary notice that was less than fully celebratory of the deceased. The Dramatists Guild said that with the death of Papp, its playwright members had sustained a grave loss, then added, in equivocation, He was impulsive, mercurial and grandiose, but he was a generous and loving promoter of our plays wherever he found them. I think Papp would have smiled at that notice, at the critical but an especially at that misspelling. Papp was mercurial in the extreme. In what may have been an attemppt to articulate his philosophy of theatre, he once said, I can bend, backtrack, switch directions, do this or that, whatever is necessary in order to survive. My tactics, out of necessity, keep changing, but my direction has never changed: new plays, new audiences. His legacy endures in the plays and playwrights he introduced, in the actors whose careers he encouraged and in the commitment to theatre that was his hallmark. Fiercely partisan, he stood up for the principles he believed in and for the plays he produced. In his extraordinary career, he found himself on both sides of the firing line as sharpshooter and as target. A favorite role was as critic of the critics and as self-appointed ombudsman, badgering and even banning reviewers when he felt they had been negligent in their responsibility. He could be self-defensive and self-destructive. In pursuit of a populist theatre, he acted as a radical in art and in politics. For him, theatre was a necessity, an instrument of social as well as cultural enhancement. He invented free Shakespeare in the park, a concept that was imitated in cities around the country and he drew many of our finest actors to challenge themselves in classics. In so doing, he brought Shakespeare to generations of theatregoers, although he never did fulfill his goal of creating an American approach to Shakespeare. His career was filled with grand schemes: a black and Hispanic classical company, the Festival Latino, a repertory ensemble that would allow for name actors to perform plays for short seasons (one of several dreams that never reached fruition). In his last years, he began a cycle of the complete Shakespearean canon. In its first life, his company was an actors theatre devoted to the works of that one playwright. But at the Public Theater, the company became a playwrights theatre, as Papp discovered writers like David Rabe and Wallace Shawn, and adopted others like John Guare, David Henry Hwang and David Hare and gave them a continuing platform for their work. After a play failed, he would ask the playwright what play he wanted to do next and then he woudl produce it, sometimes without ample regard for the works artistic merit. Similarly, a directors failure would be followed by an opportunity for redemption with another production. Papp banked on the development of careers, and with encouragement often came artistic accomplishment. He was surrounded by controversy and criticism, for what he did and for what he chose not to do. Though the New York Shakespeare Festival was the major American theatre of its time, it never produced a play by Tennesse Williams or Arthur Miller. Other significant younger writers appeared irregularly; Papps encounter with Sam Shepard, for one, was disastrous. Many of our best women writers have never had a play produced at the Public. But the theatre did present controversial works by Caryl Churchill, Ntozake Shange and Elizabeth Swados, and the Public was Vaclav Havels home in exile. Papps critical blind spots could change with the seasons, and his choice of plays was not as exclusionary as it might have seemed. His eclcticism ran from Arthur Wing Pinero to Miguel Pinero. In his theatre as in his life, he was an ardent advocate for civil and human rights, and he supported his positions through the plays he produced. He championed theh role of minorities in the theatre, crosscasting plays before that policy was generally accepted. Even when there was an urgent need for money, he rejected grants on moral grounds, and he was the first to demonstrate for free speech and against eradicating theatrical landmarks. With his natural flamboyance, he became a highly visible and therefore vulnerable figure on the theatrical landscape. The actor side of Papp could play to the grandstands, media-dramatizing his case. In the most literal sense, he was an opportunist. When he was attacked, he attached back. When he was struck by a financial crisis, he would announce an expansion. Defeat was not a word in his vocabulary. He was never at loss for ammunition; his mouth was his most effective weapon, turning failure into a psychological victory. Despite his eminence, he regarded himself as an underdog, and during his brief foray onto Broadway with a season of new plays, he boasted of his playwrights as renegades. Ironically, he became an insider, a producer who could have transformed Broadway, had he chosen to do so. He learned to use himself as a selling point, and became his own best spokesman and fund-raiser. Papps portrait, looking like a Tammany politician, would appear in advertisements for his theatre. In one daring performance venture, he did a one-man cabaret show, singing Depression songs like Brother, Can You Spare a Dime? and directly confronting his disarmed critics. As always, Papp sang and danced to his own tune. Informally and never for attribution, his people referred to him as the Godfather, a title that was not necessarily intended to be pejorative. Rewarding the faithful, punishing the faithless and the cowardly, shunning at least for a time dissidents, he was responsible for everything, including art, that emerged on stage at the Shakespeare Festival. In terms of his personal decision-making, he was not so far removed from the old Hollywood studio chiefs. Just as a self-perpetuating tycoon selected and cast movies according to his wishes, Papp decided what he wanted to do and when he wanted to do it and when he had to cut his losses. As a working director and playwright manque he could step in and assume control of an individual project. He would have preferred to write his own reviews. Where the Hollywood moguls were entrerpeneurs and, for the most part, not distinguished in matters of taste, Papp was a man of artistic sensibility and social conscience. He was shrewd, strong-willed and singleminded. He could also be sentimental. One never knew what he might do next: a cutting-edge experiment by Mabou Mines or a revival of a nostalgic Broadway comedy (Cafe Crown). He might close a show before it opened, fire a director and take over the staging, or extend the run of a play in the face of negative notices. Once had suddenly, closed a play on opening night, before my favorable review was printed in the next days newspaper. He agonized before taking over the theatre at Lincoln Center, and then when his work was on an upswing (matching innovative directors with classics), he surrendered his position and, in typical fashion, made it sound like a positive step. Papps mood was a variable as the weather in Central Park. A clear sky could rumble into a storm, but, as in the park, the performance continued. To him, theatre was not a business. He was a patron of the arts. There was always a double meaning in his concept of free Shakespeare. It was his conviction that theatre should be as public as libraries. One should be able to check out a production, as, in his youth, he could check out a book from the library in Williamsburg, Brooklyn. At the same time, he wanted to liberate Shakespeare from textbook traditionalists and elocutionary Englishmen. Papp was not a theatrical visionary like Stanislavsky or Grotowski. His theatre was not influential in the sense of the Comedie Francaise, the Moscow Art of the Berliner Ensemble. He created no new acting style, and, in the long run, the plays he produced could not be considered a body of work. However, as an institution, the Shakespeare Festival was our most important theatre. It preceded the burgeoning of the regional theatre movement, which brought about the decentralization, fragmentation and enrichment of the American theatre. As the New York equivalent of a regional company, the Shakespeare festival presaged the rise in New York of other, similarly intentioned organizations, inlcuding the Manhattan Theatre Club, Circle Repertory Company and Playwrights Horizons. When Papp was on top of several spheres, having spread his producing wings to encompass Broadway and Lincoln Center as well as Off Broadway and Central Park, I wrote, Without him, there would be a vast emptiness in the American theatre, and posed the question, Who would do all those plays, fill all those stages, employ all those actors? With Papps death, one suddenly realized how many evenings, how many hours had been spent in his theatres how much, in fact, he had determined the very course of theatre in his lifetime. Mel Gussow is a theatre critic for the New York Times. This article is based on material from a forthcoming book on Joseph Papp and the New York Shakespeare Festival. What Gives My Life Meaning EssayTHOUGHTS ON THE FUTURE   The day i walked into joseph papps office last March, he was talking David Greenspan out of directing Congreves The Way of the World with an all-male cast. When JoAnne Akalaitis phoned to intercede on Greenspans behalf, the cantankerous Papp upbraided her, declaring, Im not some sort of far-out pseudo-liberal! That exclamation might come as a surprise to those who know Papp and his causes how he has fought tirelessly for the inclusion of minorities in theatre, battled Jesse Helms in the National Endowment for the Arts controversy, and would have actively protested the Persian Gulf War had his health been better. But Papp had been going through a period of intense self-examination: He was trying to pass on his knowledge of the theatre to Akalaitis, and thus was having to think about things he had previously done on instinct. What seemed to emerge were a number of precepts that suggested Papp the Producer had quite a different set of ideals from Papp the Liberal. Q: This season you gave each of your associate directors including Greenspan a theatre with the understanding that theyd have artistic freedom in using it. Are you reneging on that? A: If I see us headed for disaster, Im going to stop it. I have a responsibility. I am an anti-censorship person, but Im also in the position in which Im saying, No, you cant do this. The New York Shakespeare Festival is an institution, not just a couple of guys and girls Off Broadway doing a show. . . .You have to be conscious of the fact that you have a $14-million-a-year operation that weve cut down to $12 million. Once I say to somebody, This is your theatre, its a relative statement. We finance it, but Im not a corporation or a foundation. Im an artistic person, so there are aesthetics in this institution. Its a delicate balance. Only someone of my experience can possibly walk that kind of tightrope. You dont practive democracy in the theatre. In arranging the New York Shakespeare Festival so it can eventually go on without you, why did you choose JoAnne Akalaitis? We have different aesthetics in a certain sense, but in terms of the way we look at life, were pretty close. I didnt want to get a duplicate of me. But I wanted somebody interesting, provocative and somebody who loves theatre. She has a single agenda: the theatre. You referred to your painful cutbacks. How worried are you about the future of the festival? Im worried, but I feel strong because of the artistic changes that are taking place. Ill lose some and gain some, but my gains will be better because they have a cutting edge on them. The directors are anything but conventional. There are at least 10 others I couldve chosen. I didnt make a mistake with any of them. Im extremely happy. You once said that if the New York Shakespeare Festival ever went down, youd rather have it die with a bang than a whimper. Now Im in a totally different frame of mind. I dont want to see this place to go down on any kind of scale. There would be a huge gap withou this institution. Have you always been a fighter? Ive been this way all of my life. I dont know if youd call that a fighter. I just hold onto things. I dont like to be pushed around, particularly on fundamental issues that affect our democratic system. Sometimes over the past few years, your role as a spokesman for various causes seemed to eclipse your life as a theatre producer. I was finding it more interesting to fight for freedom of expression than to put on plays. It was a more direct way of dealing with things. I spent months on the NEA situation because I was getting bored with the theatre. But I dont say that now. There have been many rumors about your health. Are they true? I dont know why people are so interested in somebodys health. I could say my health is nobodys business. But if Im dying, youll know it. Its not like Im some old king thats dying and making bum decisions. Nonetheless, do you ever feel any parallels with King Lear these days? No. He was crazy. Mymind has never been clearer.

Should Chinas Human Rights Record Prevent Permanent Normal Trade Relat

Should China's Human Rights Record Prevent Permanent Normal Trade Relations Background Since the initial warming of U.S.-China relations in the early 1970s, policymakers have had difficulty balancing conflicting U.S. policy concerns in the Peoples' Republic of China. From Nixon to Clinton, presidents have had to reconcile security and human rights concerns with corporations' desires for expanded economic relations between the two countries. While the U.S. regularly objects to China's human rights violations, the Chinese government counters with complaints that the American concerns represent unwarranted American intrusion into its internal affairs. In 1989 the Tiananmen Square massacre drew public attention to the inconsistent character of U.S.-China policy. A wave of public indignation with China's repressive practices forced the Bush administration to adopt a sterner posture toward human rights violations and to impose sanctions, including restrictions on bilateral and multilateral aid. But these measures have not satisfied some critics of China's human rights practices, who contend that the U.S. should apply even more rigid trade restrictions against China. Specifically, some critics insist that the U.S. government not give China permanent normal trade relations status, which would free China's government from an annual review of its human rights record by Congress. Many critics say PNTR standing should be linked to improvements in China's human and labor rights practices - a policy that has been rejected by the Clinton administration. Rather than denying China normal trading status because of human rights violations, the Clinton administration has opted for a policy of comprehensive engagement, which holds that long-term U.S. goals such as human rights improvement are more likely to be achieved through sustained contact and open trading than by further isolating China. Yet Chinese human rights practices, including respect for political and labor rights, continue to fall well below internationally accepted standards. In perhaps the stickiest issue, the White House warned last week that there was little chance of PNTR for China without legislation setting up a watchdog commission to monitor Beijing's human rights practices. China, however opposes any plans by the U.S. to monitor human rights as a condition to granting PNTR. On One Hand... American businesses should not be coddled at the expense of human rights. Despite expressions of concern for human rights conditions, the U.S. government has allowed narrow economic interests, particularly those of corporate investors, to guide its China policy. So far, the U.S. government has been unwilling to jeopardize U.S. economic relations by adopting stricter human rights conditions on aid and trade. China's trade status is currently reviewed annually by Congress. By establishing permanent normal trade relations and doing away with the annual vote, the U.S. will give up its leverage over China's human rights policies. Permanent normal relations should not be granted until long-term progress is made on human rights in China. On the Other Hand... The United States government has no authority to sit in judgment on the human rights records of other governments, especially given the U.S. government's own complicity in some human rights violations in foreign lands. You don't have to embrace a government or its policies to engage in trade. If trade were a beauty contest, we'd trade only with a small group of nations that mirror our own society, and would be in a virtual cold war with the rest. Furthermore, U.S. imposed trade barriers are unlikely to change the policies of China's communist leaders. The most powerful force for labor, human rights, and the environment is economic liberalization and global market forces. Growth and rising income give workers the chance to improve their lives. History & Facts ? In 1994 President Clinton officially delinked trade and human rights in China. According to Human Rights Watch, every year since delinkage, human rights conditions in China have gotten worse. ? According to Amnesty International's 1999 China Report: Hundreds, possibly thousands, of activists and suspected opponents of the government were detained during the year. Thousands of political prisoners jailed in previous years remained imprisoned. Some had been sentenced after unfair trials, others were still held without charge or trial. ...Torture and ill-treatment remained endemic, in some cases resulting in death. ? According to the U.S. State Department's 1998 China Human Rights Report: The Government continued to commit widespread and well-documented human rights abuses, in violation of internationally accepted norms.

It has a high fusing point, is ductile and malleable, expands slightly upon heating, and has high electrical resistance. Platinum is seldom used in its pure stage because it is too soft. The third most ductile metal, it can be drawn into a thread one twenty thousandth part of an inch in thickness. It is extremely resistant to attack by air, water, single acids and ordinary reagents, but does dissolve in hot aqua regia, a mixture of nitric and hydrochloric acids. Platinum has the unusual property of being able to absorb large amounts of hydrogen at ordinary temperatures and resist it at high temperatures. The first mention of Platinum occurs in the writings of an Italian physician and poet named Julius Caesar Salinger in 1557. A hieroglypic character made froma grain of Platinum dated back to the 7th century. Credit for discovery of Platinum has been given to Don Antonio de Ulloa, a young lieutenant in the Spanish Navy. The metal was referred to as the "platina de Pinto", meaning the siver like metal from the Pinto River. The first thorough study of Platinum was conductd in1750 by the English physician William Brownrigg. Brownrigg noted that Platinum was heavier and even more chemically inert than Gold was. Platinum forms useful alloys with many other metals, including Iridium, Palladium, Rhodium, Ruthenium, Osmium, Gold, Nickel, Cobalt, and Tungsten. At high temperatures Platinum also reacts with Chlorine, Fluorine, Phosphorus, Arsenic and Sulfur. Among the transition metals, Platinum has the greatest tendencies to bond directly with Carbon. Platinum is used extensively in modern industrial society because of its chemical inertness, high melting point, and extraordinary catalytic properties. platinum is valuable for laboratory apparatus, such as tongs, combustion boats, crucibles and evaoporating dishes. It is also used for thermometers in furnaces, for electrodes in making quantitative chemical analyses, and for corrosion and heat-resistant instruments. Platinum is used extensively in the jewelry industry for setting diamonds and other precious stones. Rocket and jet engine parts often contain Platinum alloys because they must withstand high temperatures for long periods of time. At petroleum refineries, finely divided Platinum is used as a catalyst in upgrading the octane of gasoline. In automobiles, converters containing Platinum-Palladium alloys reduce air pollution from exhaust gases. High quality optical glass for television picture tubes and eyeglasses is melted in pots lined with nonreactive Platinum alloys. A form of Platinu m,cisplatin, stops cancer cell division and disrupts its growth pattern.

Overview and History of UNESCO

Overview and History of UNESCO The United Nations Educational Scientific and Cultural Organization (UNESCO) is an agency within the United Nations that is responsible for promoting peace, social justice, human rights and international security through international cooperation on educational, science, and cultural programs. It is based in Paris, France and has over 50 field offices located around the world. Today, UNESCO has five major themes to its programs which include 1) education, 2) natural sciences, 3) social and human sciences, 4) culture, and 5) communication and information. UNESCO is also actively working to achieve the United Nations Millennium Development Goals but it is focused on achieving the goals of significantly reducing extreme poverty in developing countries, developing a program for universal primary education in all countries, eliminating gender inequalities in primary and secondary education, promoting sustainable development and reducing the loss of environmental resources. History of UNESCO When that conference began in 1945 (shortly after the United Nations officially came into existence), there were 44 participating countries whose delegates decided to create an organization that would promote a culture of peace, establish an intellectual and moral solidarity of mankind, and prevent another world war. When the conference ended on November 16, 1945, 37 of the participating countries founded UNESCO with the Constitution of UNESCO. After ratification, the Constitution of UNESCO came into effect on November 4, 1946. The first official General Conference of UNESCO was then held in Paris from November 19-December 10, 1946 with representatives from 30 countries. Since then, UNESCO has grown in significance across the globe and its number of participating member states has grown to 195 (there are 193 members of the United Nations but the Cook Islands and Palestine are also members of UNESCO). UNESCOs Structure Today The Director General is another branch of UNESCO and is the executive head of the organization. Since UNESCOs founding in 1946, there have been 11 Director Generals. The first was the United Kingdoms Julian Huxley who served from 1946-1948. The current Director General is Audrey Azoulay from France. She has been serving since 2017. The final branch of UNESCO is the Secretariat. It is composed of civil servants who are based in UNESCOs Paris headquarters and also in field offices around the world. The Secretariat is responsible for implementing UNESCOs policies, maintaining outside relationships, and strengthening UNESCOs presence and actions worldwide. Themes of UNESCO Natural sciences and the management of Earths resources is another UNESCO field of action. It includes protecting water and water quality, the ocean, and promoting science and engineering technologies to achieve sustainable development in developed and developing countries, resource management and disaster preparedness. Social and human sciences is another UNESCO theme and promotes basic human rights and focuses on global issues like fighting discrimination and racism. Culture is another closely related UNESCO theme that promotes cultural acceptance but also the maintenance of cultural diversity, as well as the protection of cultural heritage. Finally, communication and information is the last UNESCO theme. It includes the free flow of ideas by word and image to build a worldwide community of shared knowledge and empower people through access to information and knowledge about different subject areas. In addition to the five themes, UNESCO also has special themes or fields of action that require a multidisciplinary approach as they do not fit into one distinct theme. Some of these fields include Climate Change, Gender Equality, Languages and Multilingualism, and Education for Sustainable Development. One of UNESCOs most famous special themes is its World Heritage Center which identifies cultural, natural and mixed sites to be protected all over the world in an effort to promote the maintenance of cultural, historic and/or natural heritage in those places for others to see. These include the Pyramids of Giza, Australias Great Barrier Reef and Perus Machu Picchu. To learn more about UNESCO visit its official website at www.unesco.org.

A Successful Entrepreneurial Leadership Term Paper

A Successful Entrepreneurial Leadership - Term Paper Example A transactional leader always works and succeeds in an organization which only exists as it is without any conscious effort to change itself. Thus the transactional leaders focus more on the present issues and are more responsive in nature rather than being more proactive in managing the overall affairs of the organization. In such an organization, transformational leaders are least likely to be successful. (James C. Sarros & Santora, 2001) Transformational leaders, however, are more proactive and innovative in nature and therefore focus on developing solutions for the problems while at the same time taking the organizations in new directions. (Tarabishy). Transformation leaders, therefore, can succeed in those organizations which are ready to make a turnaround. Organizations which have reached their maturity stage or experiencing slow growth may be more suitable for the transformational leaders. Further, learning organizations can also be most suitable for transformational leaders b ecause they create opportunities for their followers to learn and innovate. Transactional leaders, therefore, may not be able to completely successful in learning organizations. Authentic leaders can be successful in organizations which are risk-taking and new in nature and therefore focus on making their way fearlessly. An authentic leader always ready to face anything and take unconditional responsibility, therefore, the organizations which are looking to make their way up will find authentic leaders as most suitable persons to lead the organization and make it one of the dominating forces in the industry. Transactional leaders, however, may not be successful in such organizations. Tools One of the most important tools offered through Small Business Administration as well as the Score is the information about how to secure capital for the startup of the business. Since most startup businesses fail to obtain seed capital to start their business, therefore, it is really critical tha t they must have access to the required funding.

Issue reaction Paper - Essay Example In this case, it is evident that terrorism is responsible for economic losses, loss of life, and the failure to achieve world peace with terrorism instrumental in ensuring that the basic freedoms of people are not effectively achieved. Despite the issues raised by Mathew being important and requiring urgent attention, this essay posits that terrorism is the greatest threat not only in America, but in the world over. The September 11 attacks highlighted the identification of terrorism as the greatest threat in America. As a result, discourse was shaped around terrorism and other issues largely took a backstage with the department of defense remaining one of the most funded departments in the country in order to protect the America, its citizens, and its interests.2Nonetheless, Mathew indicates that the largest challenge, and threat, that the country faces is not terrorism, but it is with issues related to the health issues such as medical insurance, underage drinking, cancer, and inef fective gun control.3 It is evident that Mathew has a point on the importance of addressing these issues. Using the issue of gun control as an illustration, there has been a great concern in the country following various incidents of mass shootings that highlight the importance of strict rules that prevent shooting incidents in school and other places. To highlight the importance of tight rules in gun control, a man opened fire in Connecticut’s Sandy Hook Elementary School and killed about 27 people last year with 18 of these people being school children.4It is important to point out that this is one incident, among many other incidents, which highlight the importance of gun control in the country. Based on this evidence, it is crucial to point out that this issue remains a threat to America although it is not as a bigger threat than the threat posed by terrorism. Unlike incidents of gun use, terrorism incidents can cause great havoc not only to the current generation, but al so to future generations. Hence, I do not agree with the statement â€Å"Terrorism is not the Greatest Threat† since the threat posed by terrorism is much more than the threat posed by these other issues that Mathew highlighted. Terrorism is responsible for creating fear in the society, which contributes to low productivity in people since they live in constant fear. In a study conducted after the 9/11 attacks, a majority of people living in major cities were afraid when going to work since they did not know when terrorists would strike next.5Other than creating fear among the citizens of America and the world over, the economic losses resulting from terrorism are enormous. In this case, it is evident that terror activities bring enormous losses that affect the country’s economy. Alone, the 9/11 attacks contributed to a $3.3 trillion loss in the economy as pointed out by experts with these losses arising from the toll and physical damage, impact on the economy, and the cost of engaging in war in order to stop future attacks.6 From the foregoing, it is evident that there are other issues that are a threat to Americans. In this case, issues related to factors such as gun control, medical insurance, cancer, and many others are a threat to America. Importantly, these issues led to Mathew’

World Literature Assignment Help Essay Example for Free

World Literature Assignment Help Essay The most important feature of Homer’s  Iliad  is the most obvious: the central issue in this poem is warfare.  In fact, the  Iliad  is our oldest, most famous, and most enduring story about men in battle.  So one might well begin by exploring certain features of this particular war narrative.  How does Homer depict the war so as to emphasize some features rather than others? Such a question is necessary because the phrase  war story  does not reveal very much about any particular fiction.   After all, warfare, particularly the Trojan War, can be and has been used to develop an astonishingly wide range of the different stories—dramatic adventures, chivalric tales, amusing satires, bitter social commentaries, historical epics, various styles of comedy, romance, and so on, often in combination.  For war is a very fecund basis for all sorts of different tales, as one might expect, given that it includes so many narrative possibilities.  So we might start by seeing if we can get a sense of some of the more salient features of Homer’s treatment of the war. One of the most initially surprising things about the  Iliad  is how many well-known details of the full Trojan War story Homer leaves out. The poem gives us no detailed sense of how the war started (either the short-term cause of Paris’ and Helen’s elopement or the long-term causes in the wedding of Thetis and Peleus and the Judgment of Paris), nor are many of the most famous incidents in the opening or closing stages of the war given any attention (for example, the sacrifice of Iphigeneia, the recruitment of Odysseus and Achilles, the abandonment of Philoctetes, the Trojan Horse, and the fall of Troy, among many others).  There are many references to the fact that Troy will eventually fall, but no details are provided.  First-time readers of the  Iliad  who have some familiarity with details of the famous narrative frequently comment, often with a sense of disappointment, on how few such incidents are included here.  One would think that any poet interes ted in holding his audience’s attention with some exciting narrative events would make much better use of at least some of these.  But one searches the  Iliad  in vain for most of one’s favorite stories from the Trojan War. Instead, the  Iliad  focuses on few weeks in the tenth year of the war. The action covers considerably less time than that, of course, because there are some major gaps (e.g., the nine days’ plague in Book 1, the twelve-day wait for Zeus, the twelve-day maltreatment of Hector’s corpse), and the focus is almost exclusively on what is going on in that relatively short time.  There’s an interesting double chronology at work.  Events move quickly from one battlefield experience to another—there is lots of exciting action.  At the same time, while there is little attention paid to a precise chronology, we also get a sense that a lot of time is going by; this war is dragging on and on, without anything changing very much (other than people being killed).  We do not experience this war as a complete event, with a beginning, middle, and end, an experience with clearly understood causes and a series of events leading to a definite conclusion.  We star t the poem in the midst of warfare, and we end the book, several weeks later, in exactly the same place.  The only thing we know for sure at the end is that the fighting will continue, as before. The warfare is also unremitting.  One bloody encounter is always followed by another without significant variation in the basic nature of the encounters and without pause.  All attempted truces are doomed to failure, other than those the parties make, ironically enough, to collect or celebrate the dead.  Even at night, when the fighting has generally stopped, the war dominates people’s actions, thoughts, and dreams.  There is none of that sense, so prominent in the  Odyssey, that an evening’s meal and sleep bring something to a conclusion so that when Dawn appears the next day, something new and different is about to begin. This narrative structure creates a sense that this war is less a particular and unique historical campaign than it is a lasting condition of life.  These warriors are doing what they have always been doing and what they will continue to do (a sense that is strongly reinforced, as we shall see, by their memories of the past and their hopes for the future).  There has been no clear beginning to all this, and there will be no clear end.  Of course, if we bring to the poem a knowledge of the details of the Trojan War, we know that the tradition tells us it does eventually end.  But the  Iliad  does not encourage us to think about that in any detail, apart from the references to the fact that Troy will fall someday, and, if we do, there is little in the poem to suggest that such an event would change anything very much (more about this later). In addition, the absence of any sense of enterprising romantic adventure in the poem (in spite of the fact that the traditional story of the Trojan War includes all sorts of possibilities for such events) generates a sense that individual resourcefulness in tactics, strategy, or trickery (a common feature of the  Odyssey  and of countless popular war fictions) is out of place here, because this war is larger than the efforts of any one man or small group of men.  It is not something which the individual warrior can, through his individual efforts, alter in any significant way.  Whatever he and his comrades do today, then tomorrow, if he is still alive, he will have to continue doing.  By the end of the  Iliad,  we have witnessed some extraordinary human conduct, glorious courage, horrible destruction, and more, none of which has changed the course or the nature of the war in the slightest.  Confronted with this situation, the men seem trapped, as Odysseus observes: Zeus sees to it that from our youthful days to our old age we must grind away at wretched war, till, one by one, we die. (14.104) [14.85] Some readers find this narrative rhythm disconcerting. Where are we going with the story?  There is a lot of action,  but overall nothing is changing and there is little if any sense of closure.  For those who expect other things from a war fiction, it is rather surprising and perhaps disappointing to discover that most of the exciting narratives we associate with this war come from other sources—the  Odyssey,  Aeneid, and  Metamorphoses, for example—where the vision of war is very different from what Homer is developing in the  Iliad. I would like to suggest that all these relatively obvious details help to create a sense that this vision of war is thoroughly fatalistic.  The war is neither a temporary problem nor a discrete historical event nor a unique adventure.  It is, rather, the basic, unchanging, and inescapable condition of life itself. It is man’s fate. Before exploring this point further, we should first clarify precisely what the terms  fate,  fatalism, and  fatalistic  mean here, for in these modern, decidedly non-fatalistic times we may not all grasp the concept clearly.  To assert that Homer pictures the war as man’s fate is to claim that Homer views it as the essential condition of life into which these men are born. They do not choose to have the world this way, and many of them express their dissatisfaction with this state of affairs and their desire for something different.  But there is nothing they can do to change that condition.  Whatever started this war and whatever will end it (if it ever does end) are beyond human control. It is necessary to add here the important point that, understood in this sense, these terms carry no necessary sense of optimism or pessimism. It is possible to be a confirmed fatalist and yet sense that the basic conditions of life are as good as they possibly could be or are arranged for man’s benefit (as in, say, a faith in providential Christianity), or, alternatively, to have a decidedly pessimistic sense of the world one is born into.  All these terms indicate, as I say, is that life is, so to speak, a game where the rules are made up and controlled by others and where human beings have no ability to change the situation. The terms  fate  and  fatalistic  also do not mean that human actions are predetermined.  This point is crucial to grasp for an understanding of the  Iliad  and almost all classical Greek literature.  Human beings may be unable to alter the situation, but in at least one essential since they are free agents.  They are free to choose how to react to these given conditions.  In the  Iliad  the men have chosen to be warriors; more than that, most of them are determined, in their freedom, to act as heroically as they can, to live up to a code which insists that they confront this grim fatal reality with a range of human qualities (courage, loyalty, physical strength, and so on). We  will be going into this feature of the poem in greater detail in another essay.  For the moment it’s essential to grasp the point that central to lives of these men is their free assertion of their individuality in the face of a harsh fate which they cannot alter.This fatali stic quality of the poem emerges also in the way Homer insists upon the universal scope of war. As we read the story, we are always dealing with a particular event involving specific individuals, but we are also aware of a larger picture, for these events are part of a much longer time period.  The famous digressions, which have occasioned a certain amount of hostile comment, serve to remind us again and again that warfare is a condition of life itself.  Flashbacks to earlier times insist that personal armed combat is what life is about (e.g., Phoenix’s long tale of Meleager, Aeneas’ boasts about his ancestors, Andromache’s story of her family, the constant reminders of the achievements of Diomedes’ father, Tydeus, and so on).  The particular events of this battle are always being played out against a historical backdrop of very similar incidents.  One of Nestor’s important functions in the poem is to remind us all the time, both by his pre sence and by his reminiscences, that human life has always involved fighting on the battlefield: â€Å"Son of Atreus, yes, indeed, I wish, I was the man I used to be back then when I cut down lord Ereuthalion.But gods don’t give men everything at once.  Ã‚  Ã‚  Ã‚  Then I was young.  Now old age follows me.But I’ll be with my horsemen, advising them, giving them  their orders, an old man’s right.Fighting with spears is for the younger men  Ã‚  Ã‚  Ã‚  Ã‚  born after me, men who rely on strength.† (4.373) [4.318] Similarly, when Hector thinks of his young son’s future, the best he can envisage for him is that he will be a great warrior, victorious in battle (6.583), a situation all the more poignant, of course, because many readers bring to the incident a knowledge of how Hector will soon die and how the young infant will be killed when the Achaeans sack Troy.  Hector has already acknowledged that he will die fairly soon, and no one in the poem has more to lose from continuing the battles than Hector.  Nonetheless, the only future he can imagine and desire for his son is one which has produced the situation he and Andromache now face. Homer’s treatment of the combatants also serves to bring out the universal, fatal condition of this war.  The  Iliad  contains hundreds of different names of people from all over the known world.  It is virtually impossible to keep track of everyone (and one doesn’t really have to, since most of the major actions involve relatively few people), but it is equally impossible to escape the sense that on this canvas we have representatives from all parts of civilization, not simply two separate groups fighting their own private quarrel.  And what’s even more remarkable, all these combatants are decidedly similar.  Most of them speak the same language, worship the same gods, live by the same code of life, share the same rituals in prayers, sacrifices, burials, and so on.  Warriors on opposite sides are members of the same extended family, and their forefathers have entertained each other and fought as allies in the past.  Some of those on different sid es have the same name (e.g., Agelaus, Antiphus, Adrestus, Medon, Noemon, Orestes, and so on).  Such a marked similarity between the two main groups of allies works against any attempt to find a rational cause of this war in some ethnic or religious conflict and thus adds weight to the impression that warfare transcends any geographical or cultural differences between the groups fighting each other. We need to dwell on this point for a moment.  In our Western traditions, we have for a very long time coped with the disturbing aspects of war by subjecting it to moral analysis. We like to see warfare as an army of righteousness against an army of evil, good versus bad, with the forces of goodness prevailing, so that we can justify the inescapable horrors war brings with it.  And many critics have extended this tradition to the  Iliad, seeking to establish some moral basis for the war which would make its atrocities somehow more palatable.  I’ll have a good deal more to say about this tendency in a later essay.  What I want to insist upon here is that Homer appears to go out of his way to make this division between the opponents difficult to sustain.  This war has not arisen out of cultural or political or economic conflict.  It is something bigger than all such conflicts, and it has the effect of making all the combatants, whatever minor differences one wishes to point to here or there, all equally subject to its force. After all, why are these men fighting?  Or, more importantly, why do they believe they are fighting?  The treatment of Helen, the ostensible cause of the war, makes her, for all her importance in the received tradition, relatively insignificant.  She is hardly a sufficient explanation for what is going on.  If the abduction counts at all, it is a minor pretext for what these men do all the time anyway.  The suggestion that the Trojans might debate the issue and give her back (7.402) evaporates almost immediately, and the war continues as before.  King Priam expressly indicates that Helen is not to blame (3.175) since the only sensible way to account for this war is to ascribe it to the gods. Such a view of war is profoundly different from what most of us now believe.  We think we have the ability to avoid warfare and that, if we must fight it, then we will do so only when we have a moral imperative to do so (i.e., when we are the â€Å"good guys† and our opponents â€Å"the bad guys†).  And even under such circumstances, we will expect the war to be as short as possible.  The notion that war is not a temporary and unwelcome intrusion upon human life but a fatal condition of life is thus potentially disturbing, a challenge to beliefs we particularly cherish.  A central thrust of these essays is that such a challenge to our sensibilities is one of the most important things about this poem because it is a vision of the world which contradicts what we wish to believe about it.  Of course, many of us can and do seek to evade that challenge by attempting to convert the grim fatalism into a reassuring moral allegory in line with our traditions, but that, it strikes me, removes from the work its most valuable qualities.

Non-determinates Prices Of Sup :: essays research papers

Most people that are common shoppers have encountered a situation where the product that they were seeking to buy was not available. It is very easy to see that certain products do have an ample supply due to many reasons. Other than the price of that product, there are six major non-determinate factors of supply. These factors are: Number of Sellers, Technology, Resource Prices, Taxes and Subsides, Expectations of Producers, and Price of other goods the Firm could Produce. With these factors and the demand of the product, the supply of a product can be determined, and a price can be set.   Ã‚  Ã‚  Ã‚  Ã‚  The number of sellers can be one of the most determining factors of the supply of a product. The concept is very easy to understand. If there are more sellers, that is more stores and manufactures, there will be a larger amount of supply of a certain product. On the other hand, if there are a small number of sellers then there will be little supply of the product. When considering the price of a product, if there are more sellers then there will be more competition; therefore, the price will be at a low cost for the buyers. The sellers will not make a large profit. Moreover, when there is a small amount of sellers then the price can be higher for the buyers. This means the sellers will make a larger amount of profit. For example; there are more sellers for a Toyota Carmry, then there are for Dodge Vipers.   Ã‚  Ã‚  Ã‚  Ã‚  This world has experienced a huge technological advancement. Our knowledge in inventing new technologies has allowed us to become more efficient in the production of products. Also, we have been able to develop many new and better products for the buyers. Technology can do two things to the supply of a product. First, it can drive the price down due to more production of a certain product. With technology, production of a certain product has become cheaper and more efficient. The second thing that technology has done is decline the supply of certain product. With the production of new and better products, older products have become less used and not produced as much. A good example of how technology has effected this world is the invention and production of CD’s. In today’s world most Americans own a CD player and have gotten ride of the record player.

What does it mean to be emotionally intelligent? How do these theories compare with each other, and do they provide adequate appraisal of competency? This essay presents a Cognitive Intelligence (CI) and Emotional Intelligence (EI) overview in modern organisations, the two most prominent cognitive processes in the field of Organisational Behaviour; it evaluates strengths and limitations in theory and practice. Furthermore, this essay offers practical recommendations for modern organisations, including a proposed integrated approach of both theories as a comprehensive model of assessment to help gain a deeper understanding of the complexity of the human mind. Organisational behaviour examines individuals and groups in the work environment (Wood et al., 2013). The human element exerts profound influence in the workplace (Presser, 2006, as cited in Lockwood, 2006). According to Armstrong, Cools and Sadler-Smith (2012), cognitive development is an essential business tool with interest increasing six folds over the last 40 years. Evidence of ability testing was found as far back as ancient China 2200 BC (Fletcher & Hattie, 2011) but the discipline was not accredited until the late 1940’s (Wood et al., 2013). In spite of its popularity, cognitive development has generated fierce debates among the experts who disagree on concepts, interpretation and terminology; this discord has generated undesired scepticism and misunderstanding (Fulmer & Barry, 2004). CI and EI explore two distinctive aspects of cognitive abilities. The more accepted of the two, with many decades of extensive research, is CI (Viswesvaran & Ones, 2002). Over a hundred years ago, Spearman (1904) introduced CI as an essential part of learning (as cited in Schmidt & Hunter , 2004). CI is â€Å"essentially the ability to learn† (as cited in Schmidt, 2002, p. 188). Gottfredson (1997) expands with terms like â€Å"catching on,† â€Å"making sense† or â€Å"figuring out what to do† (as cited in Fulmer & Barry, 2004, p. 247). CI is measured through psychometrics tests (or intelligence metric assessment) and expressed as a number called IQ or  Ã¢â‚¬ËœIntelligence Quotient’ (IQ, 2014). There are many psychometrics tests, but the most popular are the Wechsler Adult Intelligence Scale-Revised and the Stanford-Binet Intelligence Scale – frequently revised and used worldwide (Human Intelligence, 2014). IQ scores range between 85 and 115 (please see Graph 1); the further to the right, the more gifted the individual. Early research maintained that IQ scores determined a person’s intelligence (Fletcher & Hattie, 2011) but society has evolved from this limiting idea. Many theorists agree that CI remains a reliable performance measurement (Fulmer & Barry, 2004). It is hard to ignore people’s intellectual or physical differences (Fletcher & Hattie, 2011) and to this day, CI remains the most widely accepted and understood cognitive theory (Fulmer & Barry, 2004), particularly in the fields of business, medicine and education. Armstrong, Cools and Sadler-Smith (2012) attribute this renewed interest to several factors: research is now able to recognise the difference between abilities (CI) and personality (EI); the theories are easier to grasp and considered mainstream psychology; also research is conducted in a more ethical manner and the results are more convincing. This attitude is also reflected in empirical studies. Since the end of WWI, CI has been used to hire employees in the workplace (Yerkes, 1921); its use remains consistent in many behavioural categories of health risks, crime and occupation (Schmidt & Hunter, 2004). Mistakes are learnt from the past and researchers are more politically aware, ethical and flexible; morals and objectivity have replaced lack of transparency to factor human variables (Fletcher & Hattie, 2011). CI will stay as long as technology is employed at work (Salgado & Anderson, 2002; as cited in Viswesvaran and Ones, 2002). However, some limitations are present in the research. One of the most significant limitation is Tthe wide variety of definitions and terminology generates confusion and doubt (Armstrong, Cools & Sadler-Smith, 2011). For example: intelligence testing (Fletcher & Hattie, 2011), intelligence model (Roberts, Matthews & Zeidner, 2010), general mental health (GMA) (Schmidt & Hunter, 2004) and so on. Another criticism is reducing individuals to a simplistic linear value, discounting environmental and cultural variables (Fletcher & Hattie, 2011). However the biggest criticism is the neglect of other vital aspects of cognitive ability (Neisser et al., 1996, as cited in Fulmer & Barry, 2004). Studies increasingly demonstrate that a single theory no  longer provides adequate competency measures when alternatives are available (Schmidt & Hunter, 2004). CI constraints are not limited to theoretical concepts; there are a number of practical flaws. A typical CI drawback is the lack of practical use of academic skills in the real world (Schmidt & Hunter, 2004). Brody (2004) argues that a person may have knowledge of a discipline, but not the competence to put it into application in the work environment. For instance: relationship counsellors may be familiar with the theories of dealing with harassment, yet fail deliver comfort, compassion and understanding for their clients. In reverse, research shows that some individuals without education may still possess competent thinking abilities (Fletcher & Hattie, 2011). *Linking sentence here if you’re going to introduce EI next* One of the most revolutionised ideas that came out of the nineties was EI and its impact on job performance (Goleman, 1998; as cited in Cà ´tà © & Miners, 2006). Four elements define EI: thought-processing, problem-solving, learning, decision-making and interpersonal relationships (Witkin et al. 1977, as cited in Viswesvaran & Ones, 2002); the five personality dimensions of EI that affect work performance are: introversion-extroversion, conscientiousness, agreeableness, emotional stability and openness to experience (Wood et al., 2013). EI has been integrated in many organisations’ training includi ng business schools, professionals, sales, management and so on (Cà ´tà © & Miners, 2006). A number of EI tests have emerged but the most popular one is the Myers-Briggs Type Indicator (Myers, 1962, as cited in Armstrong, Cools and & Sadler-Smith, 2011). CI is far more accepted than before and research reveals EI capabilities too significant to ignore (Neisser et al. 1996, cited in Fulmer & Barry, 2004). As knowledge is easier to access anytime, anywhere in the world via technology, it is becoming less about ‘what you know’ and more about what to do with the information in terms of identifying, analysing and problem-solving (Fletcher & Hattie, 2011). EI is gaining considerable influence in the business world. Research demonstrates that EI predicts academic achievement beyond CI (Miller et al. 2007, as cited in Lyons & Schneider, 2005); it also works as a contextual predictor (Borman & Motowidlo, 1997; as cited in Viswesvaran & Ones, 2002). Where CI lacks consideration for variables, EI abilities allow for a more accurate assessment of work by accounting factor s such as culture, gender,  disabilities and other environmental elements. Additionally, these cognitive abilities, which provide big insights into the human personality and its triggers, can be developed through adulthood (Boyatzis & Sala, 2004). In the practical sphere, the same concept is found. Where CI is deficient, EI is able to balance via a number of ways; for example by discerning and interpreting emotions using body language and visual signals where knowledge and practical skills fail on the job (Rafaeli & Sutton, 1987; Sutton, 1991). And vice versa by those who lack EI and can increase their CI processes through developing interpersonal skills with colleagues to seek assistance to perform the task (Law, Wong & Song, 2004; as cited in Cà ´tà © & Miners, 2006). Consequently, EI’s theoretical limitations are almost on par with the positive attention it has received over many decades. The lack of adequate research and empirical studies are its biggest downfall (Becker, 2003; Landy, 2005; Locke, 2005; cited in Cà ´tà © & Miners, 2006). EI i s also criticised over its theory and assessment (Davies, Stankov, & Roberts, 1998). Experts can’t agree with its definition; some consider EI a function purely based on emotion, others suggest that EI is a mix of personality and emotional management (Lyons & Schneider, 2005; Cherniss, 2010). There are some mixed feelings about EI’s gain to organisations (Motowidlo, Borman & Schmidt, 1997; as cited in Cà ´tà © & Miners, 2006). On the practical side, similar flaws are present. A practical limitation of EI is apparent in the MSCEIT questionnaire where the focus is to identify the emotional aspect of abstract art; a more practical approach would be to teach management and staff basic skills in stress tactics (Cherniss, 2010). The workplace is where individuals compete for goals, promotion or reputation; studies by Joseph and Newman (2010) or Williams, Bargh, Nocera and Gray (2009) caution about the possibilities of using ‘strategic’ EI for self-promotion in the workplace through manipulation, control and self-exploitation (Kilduff, Chiaburu & Menges, 2010). To avoid mishaps, the following is a proposed model to apply CI and EI in modern organisations. There are a number of ways that CI and EI can be applied to modern organisations. 1) More studies are proving that the single theory approach is inadequate and moving towards an integration of the cognitive processes to provide a more satisfying model; where linear models are too simplistic, the critical use of moderation compensates for the other (Boyatzis & Sala, 2004, as cited in Boyatzis,  2011). Organisations would benefit by providing training in both CI and EI development on a regular and ongoing basis to override the honeymoon period of training, particularly focusing on staff with the most experience as it has been found that long term employment tends to lead to a drop in performance (Schmidt & Hunter, 2004). 2) It is important to formulate questionnaires in a clear concise fashion, and keep the content practical and focus on the topic. The audience needs to be carefully considered to keep the content appropriate, for example child counsellors versus drug rehabilitation counsellors (Lynn, 2002). 3) Provide alternative assessment styles to reach a wider audience; for example, delivered as a group or in a private interview (Cools et al., 2009). 4) Consider the relevance of a cross-cultural approach, and other variables such as gender, age group and position within the company. 5) consider a variety of medium to appeal to a wide audience; for example a video, a web-based interactive medium or virtual reality (Chan & Schmitt, 1997). 6) Do some market research relevant to the industry to ensure there are no gaps in the information delivered (Armstrong, Cools & Sadler-Smith (2012). 7) Use care and judgment at all times, respect privacy and cater for existing environment culture (open or discree t). 8) Explore areas in need of development, such as cultural, religious, and interracial. 9) Be mindful that not everyone will be at the same level of knowledge, skills, social ladder and cater for introverts and extroverts. In conclusion, there are differences between CI and EI as the two constructs cover two distinctive aspects of mental intelligence. Both are relevant and contribute to organisational behaviour, however, human behaviour is much too complex to be simplified into two single independent theories. The flaws and strengths found in EI and CI complement each other in a linear fashion (Van Rooy & Viswesvaran, 2004). In this essay, many aspects of CI and EI were explored. It was determined that in spite of a long history, a person is much more than an IQ, and that EI is still at early stage of development. Much work and development is required in the theories to further explore the human potential. To conclude, fFuture studies and competency assessment tools will be interesting to witness over the next few years if the research includes various human genetic var iables in the endeavour to find more answers to adapt to change and reach the full potential of the human personality.

Rates of reaction experiment HCl Essay Example

Rates of reaction experiment HCl Essay Example Rates of reaction experiment HCl Paper Rates of reaction experiment HCl Paper The rate of reactions is how fast something changes from its reactants to its products. For a reactions to occur, the particles must strike with enough energy. At the start of the practical only some of the reactions will have enough energy to strike with each other and create energy for the reaction to happen. We can increase the rate of reaction by changing specific conditions in order to increase the rate of collision what will happen is that one of the things what can change it is the temperature because it provides the reactant with more energy. So this means the particles will be moving around more and therefore they are more likely to collide with each other. Another one is the concentration because by increasing the concentration of a reactant we are increasing the number of particles in a certain volume. This means there is more likely to be more collisions because they is more particles with in a small space. Another one could be pressure because by increasing the pressure we are decreasing the space in what the practices can move about in. so this means the practices will be more likely to collide with each other because there is less space for them to move around. Another one could be a catalyst because this is a lower activation energy required by particles to start a reaction and provides another route for the reaction to occur, thus speeding up the reaction. In the reaction what I will carry out the equation is: Hydrochloric acid + sodium thiosulfate sodium chloride + sulphur dioxide + Sulphur + water 2HCl (aq) + Na2s2o3 (aq) 2Nacl (aq) + SO2 (g) + S (s) + H2O (l) On this experiment we will be changing the concentration of the hydrochloric acid. So if we change the concentration of the experiment we are increasing the number of practices inside the reactions. Hypothesis Based on the information’s what I put about the rate of reaction I think as the concentration increase the rate of reactions will increase as well because they will be more practical inside the experiment so they will be colliding with each other more so the rate of reaction will increase. Equipment Measuring cylinders- so we could measure how much of the chemical we was using when we did the experiment   Test tube-so we could pour the chemicals into   Test tube holder- so then when we are waiting for the test to finish we don’t have to hold the measuring cylinders we can just put them in the rack. Hydrochloric acid- so we have a chemical to react with sodium thiosulphate.   Sodium thiosulphate- so then we have something to react with hydrochloric acid   Sodium carbonate- to put the finish produce in because after the reaction the mixer starts to smell.   Stop watch- to time the time taken for the reaction to finish. Paper and marker- so we have something to look for on the other side of the test tube to test the rate of reaction Goggles- so aware eyes always stayed protected when we are doing the experiment Variables An independent variable is hydrochloric acid solution. Dependent variables is how long the reaction takes. The dependent variable was the rate of reaction. The controlled variable was the amount of hydrochloric acid contraction must be the same. If you don’t have any controlled variables then this experiment wouldn’t have worked. Limitations My limitations could have been: Human error I could have stopped the stop watch a second after the ‘X’ had disappeared, thus causing outliers in my work. The stop watch could have been faulty the button might not have been working well and may not have stopped the timer when I pressed it. Some chemicals may have been left behind in the measuring cylinder/ test tube. Distractions I may have been distracted by something such as a loud noise and I might have looked away at the exact moment that the X disappeared. The equipment that I used might have been contaminated if it wasn’t washed out properly the last time it was used. This could have caused a faster reaction because of any other unwanted chemicals still inside the equipment Lastly, there could have been a mistake in the measuring. This could have happened if I didn’t have the measuring cylinder at eye level when I poured in the chemicals. Methods The first thing that I did was prepare myself and the area around me for the practical. I pushed all stools and bags under the desk so there is no risk of anyone tripping. So that me and my classmates where safe. The next thing that I did was gather up all of my equipment/reactants and lay them out on the table. I made sure that I had everything before I started. This makes sure that my experiment runs smoothly. Then, I drew a large â€Å"X† on the white paper using the marker pen. This was important because it would help to finding out the rate of reaction. Next we measured out 2cm3 of hydrochloric acid solution and sodium thiosulphate in separate measuring cylinders. Then place them two in the same beaker and put the paper with the cross on it on the back with the cross facing towards you. Then when can no longer see the cross stop the stopwatch and listed down the time in your result table. Then pour the finished substance into sodium carbonate because the reaction will start to smell after a while so this chemical will help prevent the bad smell. Do this 3 times so it is easier for you to find out the average time taken for the cross to disappear. Then you change the concentration of sodium thiosulphate to 0. 4cm3 and 1cm3 and repeat the experiment for them to concentrations and do it 3 times for both of these concentration. So then you can see if different concentration will make the rate of reaction change. Fair test To make the investigation is a fair test I made sure:   The same person observe the reaction because different people have different eyesight so keeping the same person to observe the ‘X’ disappear is better. Use the same ‘X’ as a darker or bigger ‘X’ can increase the time it takes for it to disappear. The temperature is kept the same. Same volume of solution – total volumes need to be the same. My results HcL concentration 1st time taken 2nd time taken 3rd time taken Average time taken 0. 4 cm3 101 131 98 110 1 92 94 93 93 2 103 95 78 92 You work out the rate of reaction by 1/average time taken So for HcL the rate of reaction was: HcL concentration Rate of reaction 0. 4 0. 009 1 0. 01 2 0. 01 Analysis and Evaluation By using my results it does show that as the concentration level goes up the time of reaction goes down. On my result I think we had a limitation because for the first 2 test of 2cm3 didn’t go with the rest of the results so they are so I think we went wrong with that concentration. So for all the other results they matched what the scientific information said in my introduction so that show this experiment still went well even though we went wrong on them two results. The scientist said as the concentration goes up the rate of reaction will increase as well and the second table would show this but because of the 2cm3 results it doesn’t quite work out but for 1cm3 and 0. 4cm3 this does go with what the scientist where saying. If I did this experiment again I would make sure that the test tubes where clean because I think we didn’t wash them out properly so it affected aware results because we did 0. 4cm3 and then we did 1cm3 so I think so of the substance was still left other and it affected the 2cm3 results. This would make it better because then I think the results will show what they should show because no reactants where left other.
