English - Essay Example Undoubtedly, the internet is increasingly one of the irreplaceable means of communication, for instance, it enables individuals to keep in touch and bring different people together, allows arrangement of meetings over the net among others. Truly, the internet has transformed various aspects of our lives over the past few years, and it has also transformed the whole world into a global village. In the contemporary world, life without the internet is impossible and unimaginable because almost every individual in the world depends on it either directly or indirectly. Despite the diversity that the internet creates, the internet does not create a freer and equal world. This paper discusses this claim with reference to culture, politics and the society at large. The internet has positively influenced culture and the spread cultural values, for instance, it play a leading role in promoting a better understanding between cultures and cultural identities to emerge and communicate with each other. It promotes uniformity and homogeneity more than diversity (Porter 2013, p.62). The internet forms a common background for cultural exchange and individuals from diverse cultures are able to interact via the internet and share idea, values as well as their cultural practices. Societal members are able to easily access any information from the internet and learn about anything they desire. In addition, the internet allows cultural exploration, that is, different cultures can easily explore other cultures and understand other cultural perspectives using the internet. Actually, a person can learn about any culture by using search engine to have an access to available information about the desired culture. Before the invention of the internet, individuals used to travel to a particular society in order to learn about their culture or look for a book that has information about that

The Disaster Management in India Has Become an Issue of Ridicule Essay Example for Free

The Disaster Management in India Has Become an Issue of Ridicule Essay With being the world’s second most populous country, India faces a lot of challenges in tackling the disasters that might strike her. India was expected to have learnt from the mistakes in her past. But the case isn’t so. Till date the Disaster Management of India is not as effective as it should have been for a huge country like India. All these ineffectiveness in technology has made Disaster Management in India an issue of ridicule. Earlier in the late 20th century due to lack of technology various disasters couldn’t be predicted in time, thus the people who were affected didn’t get any information about the disaster till they were struck by it. We can see the examples of floods across various states in India the cyclones in Odisha. Had been there any modern weather forecasting and prediction systems, the people would have got knowledge about the cyclones and effective plans could have been placed for minimising the effect of disaster. But even till the date the country hasn’t progressed. The lack of technology has led the country being unable to predict the heavy rains that caused the floods and landslides in Uttarakhand. Even because of lack of trust on the weathermen because of the past failures in forecasting by weathermen the state administration didn’t issue any warnings to people about the rains. Technology also consists of latest machinery and cutting edge tools which India doesn’t pose. The govt. said in it’s budget about assigning 100 thousand crores for disaster management and mitigation purpose. This amount might seem to be very large but it is very small if we consider the whole country which has about 1.6 billion citizens living in it. Even the amount used for disaster management would be quite less because of the politics and corruption. So one can easily imagine what would be the impact when a disaster strikes India. Now even NDMA has no strategies for disaster management. After the rains and the series of cloud bursts in Uttarakha nd, the Uttarakhand govt. declared that its state disaster management team didn’t have plan how to execute the rescue operation .If this is the case then there is no use of NDMA which said that it was not prepared to handle such huge disaster. Now back to technology. At the same time when India was busy in recovery of Uttarakhand, a similar disaster struck some European countries. But there the impact of disaster was quite less because of better planning efficient disaster management. The damage due to the floods cloud bursts in those countries was very less. This show  the ineffectiveness of India in tackling disasters. Now let’s shift our focus to the relief rehabilitation in India. As compared to disaster management the relief rehabilitation is better but not at par with other countries. Let us take an example. In 2011 Japan was struck with severe earthquakes, tsunamis finally a nuclear crisis, but in Japan the relief and rehabilitation work was quite instant and the country came back to normal life within a month or so. Meanwhile, In India the series of floods cloud bursts have disturbed Uttarakhand and even till today after 2 months relief work is going on. Who should be blamed for this? Only and only our govt. should be blamed. Had the govt. had been prepared for tackling this issue , today Uttarakhand wouldn’t have such devastation. Even the hand of politics cannot be neglected in Disaster Relief rehabilitation. Parties often adopt str ategies which would benefit them in next elections. They only think of their future thus this leads to failure in disaster management. Had it been japan, life would have sprung back in a single week. With cities expanding and developing in an unplanned manner, there would be a great loss in case of a disaster striking such cities. For example unsafe building practices in rapidly growing urban settlements constitute one of India’s greatest challenges for disaster management. A major earthquake in any of India’s densely and heavily populated cities in seismic zones would be catastrophic in terms of fatalities. Government of India has also launched various policies the implementation of NDMA under the Disaster Management Act of 2005. The objective of the authority has been to lay down policies and guidelines for effective management, risk mitigation and prevention of disasters in the country. However, in Uttarakhand, people were caught unawares by the series of flash floods and landslides in the absence of any mitigation measure or early warning despite the state having a history of such disasters and the weathermen predicting about it. The post disaster relief response has been equally poor—more than 70,000 people are reported missing. NDMA was constituted under the Disaster Management Act of 2005 to draft policies and guidelines on disaster management, approve and coordinate the implementation of plans for disaster preparedness and manageme nt at the Central, state and ministerial levels. The authority is headed by the prime minister. However, in the past seven years, the authority has been ineffective in carrying out most of its functions. NDMA had initiated  projects for flood mitigation and landslide mitigation at the national level in 2008. However, those projects have either been abandoned midway or are being redesigned because of poor planning. The projects to prepare national vulnerability atlases of landslides, floods and earthquake are also incomplete. Experts feel if such projects would have been implemented properly the damage in Uttarakhand could have been much less. The CAG report also highlighted several other loopholes in the functioning of NDMA. It said none of the major projects taken up by NDMA was complete even after seven years of its functioning. The projects were either abandoned midway or were being redesigned because of initial poor planning. The major projects include producing vulnerability atlases for floods, earthquakes and landslides, national landslide risk mitigation project, national flood risk mitigation project and national disaster management information system. As per the CAG report, NDMA has also not been performing several functions as prescribed in the Disaster Management Act. These include recommending provision of funds for the purpose of mitigation and recommending relief in repayment of loans or for grant of fresh loans. Besides, several critical posts in NDMA are vacant and consultants were used for day to day working. One can then easily say what would happen if India is struck by a major disaster. In layman’s language one can say that all these things have one message in common – THE DISASTER MANAGEMENT OF INDIA HAS BECOME AN ISSUE OF RIDICULE. The time has come for the citizens to take action in their hands and perform their duties . If not now it’s never and in future India’s disaster management will always remain an issue of ridicule among the people of he world because of it’s inability to tackle issues perform necessary actions.

what we ought to eat :: essays research papers

Christine Cuomo spoke about many interesting topics on what we ought to eat. She presented a very good argument on how eating meet is what we should no be eating and that rather more healthier foods such as fruits and vegetables are better for us in several ways and for many reasons. Christine is an ethics professor at the University of Cincinnati and during here presentation she made arguments that were somewhat controversial about what people ought to eat and what they shouldn’t ought to eat; and why. Even though some of here argument were controversial she seemed to put her perspective in very understandable ways that even those against her position would still enjoy hearing what she has to say. She is a vegetarian but is not one to force the idea on you, and she still eats cheese and drink milk. She talks about how animals are slaughtered for food and its not fair to them. She presents an argument on how butchers treat animals horribly and even though they are a source fo r our food they is no reason for animal brutality. During the presentation there was a picture of a high pile of pigs slaughtered. The picture was quite grossum and didn’t need much words to tell the story. Animals are just treated very violently as if they have no type of feeling for pain. This is not right. Personally I would like to see animals treated better before they are slaughtered because they have feelings of pain just as we do. I wish more people, including myself, can have the will power to stop eating meet to send a message to their butchers and factories that are displaying such animal brutality.   Ã‚  Ã‚  Ã‚  Ã‚  Being a vegetarian is tuff, especially if your from a nonvegeatarian family. However, Christine made her argument not only how meatless foods are good, but how simply eating less is a good start. Its hard to ask someone to top eating meet but it’s a nice gesture to try to eat less. Eating less helps, less animals will be needed to food and maybe a message will be sent to those who practice brutal ways on animals. One interesting point was that animal eat a lot. And its better for the world to have them dead then alive and eating more. This is not a right way to think. Animals were put on this earth by the same supreme being that put us on this earth.

Database Models :: essays research papers

In this paper I will be discussing the differences and similarities of the three database models we have talked about in class the Entity-Relationship, Object model, and the UML modeling. First let’s look at the definition of the three models. The Entity- Relationship Model is used to visually represent data objects and is used for database design. It is easy to understand which makes it easier to communicate the design to the end user. The form used in the ER model can easily be transformed into relational tables. (Information Technology Services [ITS], 2004) Another database model we went over in class is the Object Model. There are three concepts to understanding the Object Models one of them being the Data Abstraction which is the process of condensing data down to its essentials. Another one is the Inheritance in the object model is the means of defining one class in terms of another. The third concept in the object model is the Encapsulation which is the concept of including processing or behavior with the object instances defined by the class. Encapsulation allows code and data to be packaged together. The third database model would be the UML model that stands for Unified Modeling Language used for writing software blue prints. The UML can be used to visualize, specify, construct, and document the artifacts of a software-intensive system. (Safari Tech Books Online, 2002, chap. 2) Some of the similarities in the database model are that all three can be used in the database design process in some way. In our previous class DBM 380 we used the ER model for our projects even from our preceding projects we can create the database model in an Object or UML model. Of the three database models I find that the Entity Relationship model was the easiest to create and explain to an end user it also transforms effortlessly into relationship tables which worked well in Access. The Object model and UML model seem to be more of a language model than the ER model seems to be more for just databases although the Object model addresses both programming and databases. The UML model is more for intense software programming such as Java programming it would allow you to visualize and document your programming steps before starting the code.

Response Paper: Don Quixote de la Mancha Essay

â€Å"Don Quixote de la Mancha† by Miguel de Cervantes is one of the most recognizable classics in the world of literature. It is a narrative that is being retold in almost every generation that had followed since its publication. Much the success of the story is really undeniable as it had even infused a term to the English language, the term â€Å"quixotic. † It is certainly one of the most unforgettable stories ever written. Here is a quote from the text that I would like to pose a response: â€Å"I shall never be so mad as to make myself a knight-errant for I see well enough that things are not how they used to be in those days, when they say those famous knights rule the world† (Cervantes 161) This line was spoken by the innkeeper in the first part XXXII The tone of this particular quote seems to a response to the main theme of the story. This main theme is Don Quixote’s idea desire to live a life of a knight. The quote implies that to follow an ideal or a dream would be a waste of time. This particular quote stands out because it is one of the few pessimistic statements in the very positive, or shall I say â€Å"quixotic† theme of the narrative. This is the kind of statements that would be uttered by those who forget how to dream. People that would say this kind of words are the type that brings the hopes of other people down. The context is just like when pessimists argued that man cannot go space. The kind of thinking that pessimists have is what makes life look miserable and dull. Fortunately, Miguel de Cervantes had introduced to us Don Quixote—some who would always remind us that it is just alright to dream and seek adventures in life. Work Cited Cervantes, Miguel de.

Heinrich Himmler, Nazi SS Head Oversaw the Holocaust

Heinrich Himmler, Nazi SS Head Oversaw the Holocaust Heinrich Himmler was a key figure in the Nazi party and leader of the feared SS. He was also responsible for turning the racist and anti-Semitic ideology of the Nazi movement into a shockingly efficient killing machine. Himmlers fanatical devotion to Hitler, as well as his fascination with the pseudoscience that fortified Nazi beliefs, made him one of the main architects of the Holocaust. The unlikely rise of Himmler from an unimpressive clerk-like figure running a small farm to one of the most powerful men on earth was attributed to his penchant for organization. Upon his suicide, soon after hed been captured and the Nazi regime had crumbled, the New York Times noted that Himmler had â€Å"raised wholesale slaughter to a science.† Fast Facts: Heinrich Himmler Known For: As head of the Nazi SS elite troops, he terrorized much of Europe and masterminded the HolocaustBorn: October 7, 1900 in Munich, BavariaDied: May 23, 1945 in Luneberg, Germany (committed suicide after being captured)Spouse: Margarete Concerzowo, known as MargaChildren: Gundrun Himmler, born 1929 Early Life Heinrich Himmler was born in Munich, Bavaria, on October 7, 1900. His father, Gebhard Himmler, was a schoolmaster. Early in his career, Himmler’s father had been appointed the tutor of Prince Heinrich of Bavaria, and Himmler was named in honor of the prince. Growing up in a middle-class family with an older and younger brother, Himmler developed a great sense of pride in German traditions. When his older brother joined the military in World War I, he wrote in his diary that he wished he was old enough to enlist. He did eventually join the German army and received training, but the war ended before he saw action. Following the war, Himmler studied agriculture and seemed destined to be a farmer. Like other young and angry Germans, he responded to his country’s defeat and perceived humiliation by the Allied powers by becoming interested in nationalist political movements. He officially joined the small Nazi Party in August 1923. He was involved in a minor role, manning a barricade and holding a Nazi banner in the Munich beer hall putsch that November. After the failed takeover attempt, he escaped prosecution and avoided prison, unlike Hitler and other participants. Rise to Power As the Nazi Party grew, Himmler became a key figure. In 1925, Himmler joined the SS (Schutzstaffel, the Nazi paramilitary organization), which had originally been a thuggish group of bodyguards tasked with protecting Hitler at public gatherings. As the second-in-command at the SS, Himmler dealt with fairly mundane tasks such as increasing party membership, collecting dues, and canvassing for advertisements for the party’s newspaper. In 1927 Himmler met his future wife, Margarete Concerzowo, known as Marga. They married in July 1928, and with Marga’s money they bought a small farm about ten miles outside Munich. They kept hens and grew some produce, and proceeds from the farm augmented Himmler’s salary from the Nazi Party. At some point, Hitler recognized Himmler’s fanatical loyalty and talent for organization, and in January 1929 he appointed him Reichsfuhrer SS, essentially making him the head of the organization. Himmler had a grand vision for the SS. He saw the black-uniformed troops as elite soldiers for Hitler, modern-day knights in service to the Nazi movement. As Hitler moved to seize power in Germany in the early 1930s, Himmler made plans to increase the size and power of the SS as well as its racial composition. In 1932 he issued a marriage code for the SS. Based on the concept of Blut und Boden (blood and soil in English) expounded by Nazi theorist Richard Walter Darre, the code stressed the racial purity of SS members. By Himmler’s orders, prospective members of the elite group had to prove they were of pure Nordic stock. Potential wives of SS members had to submit to physical examinations and prove they were free of Jewish or Slavic ancestry. Himmler became fixated on the idea of selective breeding. Heinrich Himmler, left, and Adolf Hitler review SS troops. Getty Images   Building the SS Himmler accelerated SS recruiting, and by 1932 the organization had grown to more than 50,000 men. Within a few years, the SS grew to more than 200,000 and became a formidable presence in German life. A major boost to Himmler’s plans came when he happened to meet a young German who had been forced out of the German navy. Reinhard Heydrich had family connections which led him to Himmler, and Himmler, believing Heydrich had intelligence experience, hired him to perform a particular mission: build a spy network within Germany. Heydrich had not actually worked in military intelligence, but he was a fast learner and before long he had an efficient network of spies and informers. An early sign of what was coming occurred in 1933 when Himmler and Heydrich opened the first concentration camp. The Dachau camp was created to hold political dissidents and it served as a warning to anyone who opposed the Nazi regime. Throughout the 1930s Himmler acquired more power. In 1934 he participated in the notorious Night of the Long Knives, the purge of the leadership of the SA, the Nazi stormtroopers, an organization which rivaled the SS. Having won the power struggle with the SA, Himmler became known as a major figure in the Nazi leadership. In 1936, the New York Times published a front-page article noting that Himmler had become the head of all â€Å"Reich Police.† By the end of the 1930s the SS had become the dominant force within the Nazi Party. And Himmler as head of not only the SS but the Gestapo, the secret police, was established as the most powerful figure in Germany after Hitler. Heinrich Himmler inspecting a camp holding Russian prisoners of war. Getty Images Directing the Holocaust Himmler’s main historical significance was for the role he played in the Holocaust, the Nazi’s systematic slaughter of millions of European Jews. From his early youth Himmler had been an ardent anti-Semite, and he eagerly used his great power to persecute the Jews in Germany. When Germany invaded Poland in 1939, militarized units of the SS were part of the invasion force. Under Himmler’s direction, SS troops were tasked with removing undesirable populations, which generally meant Jews, from areas conquered by German troops. SS units called Einsatzgruppen rounded up Jews and killed them in massacres across Poland. When the German forces attacked the Soviet Union in June 1941, SS units followed to conduct racial cleansing at a vast level. Himmler’s work at eliminating Jews in Europe moved quickly. By late 1941 large-scale massacres by SS troops had occurred. At the Wannsee Conference in January 1942, Heydrich laid out SS plans to come up with a Final Solution for Jews in Europe. This plan for mass murder was followed by Himmler after Heydrich was assassinated by partisans months later. Himmler directed the mass murder of millions and paid close attention to what was happening in the concentration camps. It is known that he visited the death camp at Auschwitz on two occasions. At times he issued detailed orders about how the camps should be run, even explaining in detail how much food prisoners should be given. He also authorized the gruesome medical experiments conducted by Nazi doctors who used concentration camp prisoners as subjects. As part of the Nazi campaigns in Eastern Europe, many Jews were forced to live in ghettos, where they were isolated in overcrowded and brutal conditions. Himmler took a great interest in the Warsaw Ghetto, and when the Jews rose up in a rebellion in the spring of 1943, he gave orders to conduct a brutal campaign that amounted to extermination of the residents. As World War II expanded and the Germans began to suffer defeats, Himmler made plans to create SS guerrilla units which would conduct warfare against the Allies in the event Germany was forced to surrender. In 1944 he was put in the field at one point to command troops, but as he had no real military experience, he was ineffective. Hitler called him back to Berlin to command troops positioned there. Downfall In early 1945, when it became evident that Germany would lose the war, Himmler tried to reach out to the Americans to make a peace deal. He hoped to evade prosecution as a war criminal. The American commander in Europe, General Dwight D. Eisenhower, refused to consider Himmler’s peace offer and declared him a war criminal. Hitler was enraged by the betrayal and stripped Himmler of his power. As Germany was collapsing, Himmler sought to escape. He shaved his distinctive mustache, dressed in civilian clothes, and tried to blend in with the refugees traveling on the roads. Himmler was stopped at a checkpoint manned by British soldiers and he was able to produce fake identity papers. However, he aroused the suspicion of the British, who took him into custody and turned him over to intelligence officers. When questioned, Himmler admitted his real identity. While being searched on the night of May 23, 1945, Himmler managed to put a vial of poison in his mouth and bite down on it. He died minutes later. A dispatch by the Reuters News Service published in the New York Times on May 25, 1945 was headlined Himmler Outsmarted Himself. The story noted that Himmler, who had created a system of Germans often having to show identity papers to members of the Gestapo, would have had a set of fake identity papers created for himself. But in the chaos of the war’s end, few refugees on the roads still had their papers. Himmler’s pristine set of papers was what drew attention at the checkpoint. Had he simply claimed he was a refugee trying to walk home and had lost his papers, the British soldiers at the bridge might have waved him along. Sources: Heinrich Himmler.

Biography of The Pitsburgh Steelers

Biography of The Pitsburgh Steelers Free Online Research Papers The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. They are currently a member of the North Division of the American Football Conference (AFC) in the National Football League. Founded in 1933, the Steelers are the oldest franchise in the AFC. Pittsburgh has won more Super Bowl titles (six), won more AFC Championship Games (seven) and hosted more conference championship games (ten) than any other AFC or NFC team. They have played in more AFC conference championship games than any other team and are tied with the Dallas Cowboys with 14 championship game appearances in either the NFC or AFC contests. With the exception of the 1960s which featured only three Super Bowls, the Steelers have appeared in at least one Super Bowl in every decade of the contest. The Steelers won their most recent championship, Super Bowl XLIII, on February 1, 2009. The fifth-oldest franchise in the NFL, the Steelers were founded as the Pittsburgh Pirates on July 8, 1933, by Art Rooney, taking its original name from the National League baseball team of the same name, as was common practice for NFL teams to do at the time. The ownership of the Steelers has remained within the Rooney family since its founding. The current owner is Arts son, Dan Rooney, who has given much control of the franchise to his son Art Rooney II. The team enjoys a large, widespread fanbase nicknamed Steeler Nation and currently play their home games in Heinz Field on Pittsburghs North Side, which also hosts the University of Pittsburgh Panthers. Built in 2001, the stadium replaced Three Rivers Stadium which hosted the Steelers for 31 seasons. Prior to Three Rivers, the Steelers had played their games in Pitt Stadium and Forbes Field. Franchise history The Pittsburgh Steelers of the NFL first took to the field as the Pittsburgh Pirates on September 20, 1933, losing 23–2 to the New York Giants. Through the 1930s, the Pirates never finished higher than second place in their division, or with a record better than .500 (1936).[ Pittsburgh did make history in 1938 by signing Byron White, a future Justice of the U.S. Supreme Court, to what was at the time the biggest contract in NFL history, but he played only one year with the Pirates before signing with the Detroit Lions. Prior to the 1940 season, the Pirates renamed themselves the Steelers. During World War II, the Steelers experienced player shortages. They twice merged with other NFL franchises to field a team. During the 1943 season, they merged with the Philadelphia Eagles forming the Phil-Pitt Eagles and were known as the Steagles. This team went 5–4–1. In 1944, they merged with the Chicago Cardinals and were known as Card-Pitt (or, mockingly, as the Carpets). This team finished 0–10, marking the only winless team in franchise history. The Steelers made the playoffs for the first time in 1947, sharing first place in the division at 8–4 with the Philadelphia Eagles. This forced a tie-breaking playoff game at Forbes Field, which the Steelers lost 21–0. That would be Pittsburghs only playoff game for 25 years, though the Steelers did qualify for a Playoff Bowl in 1963 as the second-best team in their conference, though not considered an official playoff. In 1970, the year they moved into Three Rivers Stadium and the year of the AFL-NFL merger, the Pittsburgh Steelers were one of three old-guard NFL teams to switch to the newly-formed American Football Conference (the others being the Cleveland Browns and the Baltimore Colts), in order to equalize the number of teams in the two conferences of the newly-merged league. Logo and uniforms The Steelers have used black and gold as their colors since the clubs inception, the lone exception being the 1943 season when they merged with the Philadelphia Eagles and formed the Steagles; the teams colors at that time were green and white as a result of wearing Eagles uniforms. Originally, the team wore solid gold-colored helmets and black jerseys. Unique to Pittsburgh, the Steelers black and gold colors are now shared by all major professional teams in the city, including the Pittsburgh Pirates in baseball and the Pittsburgh Penguins in hockey. However, the Penguins use Vegas Gold, a color similar to metallic gold, and the Pirates gold is a darker mustard yellow-gold, while the Steelers gold is more of a bright canary yellow. Black and gold are also the colors of the citys official flag. (1963–Present) The Steelers logo was introduced in 1962 and is based on the Steelmark, originally designed by Pittsburghs U.S. Steel and now owned by the American Iron and Steel Institute (AISI). In fact, it was Cleveland-based Republic Steel that suggested the Steelers adopt the industry logo. It consists of the word Steelers surrounded by three astroids (hypocycloids of four cusps). The original meanings behind the astroids were, Steel lightens your work, brightens your leisure, and widens your world. Later, the colors came to represent the ingredients used in the steel-making process: yellow for coal, red for iron ore, and blue for scrap steel. While the formal Steelmark logo contains only the word Steel, the team was given permission to add ers in 1963 after a petition to AISI. The Steelers are the only NFL team that puts its logo on only one side of the helmet (the right side). Longtime field and equipment manager Jack Hart was instructed to do this by Art Rooney as a test to see how the logo appeared on the gold helmets; however, its popularity led the team to leave it that way permanently. A year after introducing the logo, they switched to black helmets to make it stand out more. The current uniform designs were introduced in 1968. The design consists of gold pants and either black jerseys or white jerseys, except for the 1970 and 1971seasons when the Steelers wore white pants with their white jerseys. In 1997, the team switched to rounded numbers on the jersey to match the number font (Futura Condensed) on the helmets, and a Steelers logo was added to the left side of the jersey. The current third uniform, consisting of a black jersey with gold lettering, white pants with black and gold stripes, and a gold helmet were first used during the Steelers 75th anniversary season in 2007. They were meant to evoke the memory of the 1963–1964 era uniforms. The uniforms were so popular among fans that the Steeler organization decided to keep them and use them as a third option during home games only. In 2008–2009, the Steelers became the first team in NFL history to defeat an opponent three times in a single season using three different uniforms. They defeated the Baltimore Ravens in Pittsburgh in Week 4 in their third jerseys, again Week 15 in Baltimore in their road whites, and a final time in the AFC Championship in Pittsburgh in their home black jerseys. Rivals The Pittsburgh Steelers have three primary rivals, all within their division: (Cleveland Browns, Baltimore Ravens, and Cincinnati Bengals). They also have rivalries with other teams that arose from post-season battles in the past, most notably the New England Patriots, Oakland Raiders, Tennessee Titans and Dallas Cowboys. They also have an intrastate rivalry with the Philadelphia Eagles, but under the current scheduling rules the teams only play each other once every four years. Divisional rivals 1.The Cleveland Browns and the Steelers have been divisional rivals since the two cities teams began playing against each other in 1950. After posting a 9–31 record in first 40 games of the series between the two cities, the Steelers recently took over the all-time series lead for the first time ever (60–56); partly due to their dominance over the post-1999, Cleveland Browns (or New Browns) franchise and won the last twelve straight before the Browns snapped their losing skid against them by beating them 13–6 on December 10, 2009. Additionally, the Browns lost 16 straight years in Pittsburgh from 1970–1985 and posted an abysmal 5–24 record at Three Rivers Stadium overall. Former Steelers head coach Bill Cowher coached the Browns special teams and secondary before following Marty Schottenheimer for a brief tenure as Kansas City Defensive Coordinator, and then hired by Pittsburgh. This has only intensified the rivalry. 2.The Baltimore Ravens and the Steelers have had several memorable match-ups and have a bitter divisional rivalry. Both teams handed the other their first losses at their current home fields. The Steelers won the inaugural game played at Baltimores MT Bank Stadium in 1998, 20–13, and three years later the Ravens handed the Steelers their first-ever loss at Heinz Field, 13–10. Later that season (2001) Pittsburgh won a divisional playoff game 27–10 against Baltimore, who was the defending Super Bowl champion. During their NFL championship season in 2000, the Ravens defeated the Steelers in Pittsburgh, 16–0, in the season opener with the Steelers later exacting revenge, 9–6, in Baltimore (the Ravens final loss of the season). During the Steelers 2008 Championship run, they beat the Ravens three times, including a win in the AFC Championship game. The Steelers lead the series (begun in 1996), 16–10. The two teams complement each other by consiste ntly fielding strong defenses in their division. The Steelers-Ravens Rivalry really began when Art Modell moved the his Franchise from Cleveland to Baltimore. The Steelers saw the Ravens as Modells team, which was reason enough to want to beat them. The Steelers also looked at Modells move of his franchise from Cleveland to Baltimore as taking away the Steelers longest and deepest rivalry away. 3.The Cincinnati Bengals rivalry with Pittsburgh dates from the 1970 season, when the NFL-AFL merger was completed. In 1976, the Steelers kept their playoff hopes alive (they later won the division) with a late-season 7–3 win in snowy Cincinnati. One of the most memorable games was the 2005 AFC Wildcard playoff game, in which the Steelers, en route to a Super Bowl title, won a 31–17 come-from-behind victory after Bengals QB Carson Palmer was forced to leave the game with a knee injury. The knee injury happened when nose tackle Kimo von Oelhoffen fell forward into Palmers knee. The Bengals players called this a dirty play, the NFL ruled that it was accidental and did not fine von Oelhoffen for the hit. This incident has led to an intensifying of the rivalry since this game. The Bengals beat the Steelers in week 13 of the 2005 season 38–31, and wide receiver T.J. Houshmandzadeh used a Terrible Towel to polish his cleats while walking up the tunnel after the game, f ueling the rivalry. The Steelers and Bengals finished 2005 and 2006 with identical records (11–5 and 8–8 respectively), splitting both regular-season series, the Bengals winning the tiebreaker both years due to having a superior division record. The Steelers also are responsible for ending the Bengals season in Cincinnati two years in a row, eliminating them from the playoffs in 2005 and taking them out of contention in 2006. The Steelers lead the all-time series, 47–30. Stadiums In 2001 the Steelers moved into Heinz Field as their football-only state-of-the-art stadium. But the franchise dating back to 1933 has had several homes. For thirty-one seasons the Steelers shared Forbes Field with the Pittsburgh Pirates from 1933 to 1963. In 1958 though they started splitting their home games with the football only Pitt Stadium three blocks away at the University of Pittsburgh. From 1964 to 1969 the Steelers played exclusively at the on campus facility before moving with the Pirates to Three Rivers Stadium on the citys Northside. Three Rivers is remembered fondly by the Steeler Nation as where Chuck Noll and Dan Rooney turned the franchise into a powerhouse, winning four Super Bowls in just six seasons and making the playoffs 11 times in 13 seasons from 1972 to 1984, the AFC title game seven times. Since 2001 however a new generation of Steeler greats has made Heinz Field legendary with multiple AFC Championship Games being hosted and two Super Bowl championships.

More rosters Steeler Nation Steeler Nation is the unofficial name of the fan base of the NFLs Pittsburgh Steelers, coined by NFL Films narrator John Facenda in Blueprint for Victory, the teams 1975 highlights film. Steeler Country is often used for the Pittsburgh area where the fan base originates or for areas with a large Steelers fan base. History Early years The Steelers have had a following in Western Pennsylvania since Art Rooney bought the team with $2,500 of his own money, and not, as myth would have it, from his winnings as a horse race handicapper. That year, Pennsylvania relaxed its blue laws allowing sporting events in the commonwealth on Sundays, paving the way for the Steelers and the Philadelphia Eagles to begin play for the 1933 NFL season. Previously, the state had teams in Pottsville and Frankford, but both had already folded, due to both the Great Depression and their inability to play on Sunday, when most NFL games took place. Much like the league itself in the early years, the Steelers had to compete with baseball and college football teams in the city, making the team third in the hierarchy to the Pirates and the Pitt Panthers. Despite the teams early struggles, it had a small but loyal fan base in the city due to the popularity of American football at all levels, dating back to the 1800s, when Pittsburgh hosted the first wholly professional football game in 1895. Rise of the Steelers By the 1950s, the Steelers had gained some popularity in the city and were on par with Pitt, but they were still a distant second behind the Pirates in the city. In the early 1970s, the Steelers began to rise in popularity, due to changes made by the team in 1969 that saw the hiring of head coach Chuck Noll and the drafting of future Hall of Fame defensive tackle Mean Joe Greene. By 1972, the Steelers were a playoff contender and began a sellout streak in Three Rivers Stadium that carried over to Heinz Field and still stands to this day. The team is second to the Washington Redskins for the longest active consecutive sellout streak in league history. The teams four Super Bowl victories in the 1970s coincided with the a recession that struck the United States, and the city in particular, that would lead to the closure of several steel mills in the early 1980s. The teams success was credited with giving people in the city hope and leading to the increased fan base. Due to economic uncertainty in the area, many Steelers fans relocated to other areas but retained their identification with the Steelers as a reflection of their former hometowns steel industrial base. During the lead up to Super Bowl XIII between the Steelers and the Dallas Cowboys, Phil Musick contrasted the Dallas and Pittsburgh fans by saying that Dallas is superfan Whistling Ray and a hat that sprays the unsuspecting with water; Pittsburgh is a guy in a gorilla suit wholl stove five of your ribs if you laugh at him. Player fan clubs In the 1970s many fans organized fan clubs for their favorite players. Some of these fan clubs included Francos Italian Army, Frenchys Foreign Legion, Gerelas Gorillas, Bradshaws Brigade, Lamberts Lunatics, Dobre Shunka (Good Ham, for Jack Ham),Rocky and the Flying Squirrels, Shells Bombers, and Russells Raiders among others. Today Since the 1970s, the Steelers have enjoyed a large fan base and have eclipsed the Pittsburgh Pirates as the most popular sports team in Pittsburgh. While the teams success gained it a large fan base nationally, many consider the collapse of the citys steel industry to have been a cause for the strong fan base in other cities, demonstrated when teams whose home turnout would otherwise require a local blackout on television end up selling out when hosting the Steelers. The Cincinnati Bengals are perhaps the best example of this, as throughout the 1990s, the team usually only sold out home games when playing against the Steelers. Another instance of the teams large fan base was at Super Bowl XL, where an ESPN.com columnist suggested that Steelers fans outnumbered Seattle Seahawks fans more than 25 to 1. In November 2007, a study by Turnkey Sports found that the Steelers brand was the strongest in its local market of any team in the NHL, NBA, MLB or NFL. Another study found that the percentage of female fans in the Pittsburgh market was more than double the average. Comparison to other NFL fans Attempts at quantifying the loyalty of Steeler Nation relative to other NFL fan bases have shown mixed results. A 2006 study by the American City Business Journals placed the teams fans 21st out of 32 teams in the league, behind all three of its division rivals in the AFC North. The study found that although the team had been selling out games for years, some fans were not actually attending the games, and Pittsburghs weekly turnout percentage for home games was 16th in the league. That ranking was down seven slots from the publications survey conducted in 1997, which ranked Steeler Nation 14th out of 30 teams, partly due to fans leaving nearly 10 percent of the seats in the stadium empty. Conversely, A 2008 study from Forbes.com ranked Pittsburgh fans 8th overall, citing amongst other things a long season-ticket waiting list. A 2008 article for ESPN.com ranked Steelers fans as the best in the NFL, citing their unbelievable sellout streak of 299 consecutive games. Criticism Like other large and vocal fan bases, such as the Cleveland Browns Dawg Pound or fans of the New York Yankees, Steeler Nation has at times been presented in an unflattering light, especially by fans of other teams. They have occasionally been described in unflattering terms by sports journalists in other cities. For example, prior to Super Bowl XLIII, the Phoenix New Times warned fans of the Arizona Cardinals that Steelers fans were the grubbiest, loudest, and nastiest fan base in all of sports - as well as one of the largest and being the only NFL team based in Appalachia, that they were white trash and hillbillies. Steelers fans have also been singled out by newspapers in rival cities for inappropriate behavior during games - a common problem in the NFL Anti–Steeler Nation sentiment has grown strong enough that in some cases, front offices for other teams have taken steps to keep Pittsburgh fans out of games in their cities. Instead of being permitted to buy tickets to a Chargers-Steelers game in San Diego, for instance, they were required to pay for tickets to two other games, as well. In other cases, teams refused to sell tickets to fans calling from Pittsburghs 412 area code, and they encouraged fans who were selling their own tickets to do the same. Steelers President Art Rooney II complained to the NFL about the situation, but his grievance was not well received. Famous fans One notable members of Steeler Nation include President Barack Obama, rapper Snoop Dogg, actors Burt Reynolds and Michael Keaton, former MLB pitcher Curt Schilling, former CIA Director Michael Hayden, talk show host Rush Limbaugh, Bishop Thomas J. Tobin of the Diocese of Providence, Rhode Island, country music legend Hank Williams, Jr., author John Grisham, actor Verne Troyer, musician Bret Michaels, and PGA Tour golfer Jim Furyk.

Managing for ethical conduct in a global business environment

Managing for ethical conduct in a global business environment Since customs, culture and norms can be very different from their own, managers need to learn how to adapt to different cultures. .A good way to do this is by learning their language. In fact, according to this chapter, "language is an essential part of cultural learning and contributes to productive international business experience."(pg.318)In addition, learning about how people behave and conduct business in other countries is essential. Therefore, companies need to provide language training and guidance for the expatriate managers because this will help them be more effective in foreign assignments. In fact, being in a foreign country can present many challenges for the expatriate manager. Some of these challenges have to do mainly with ethical issues. For instance, employers in the United States usually hire employees with whom they have no personal relationship, but who have high skill and qualifications rather than a friend or relative who is less qualified for the job.Corpora tion: PeopleThis is part of our culture. But people from Spanish countries and Asia will consider this kind of practice unethical since they place more value on hiring family members or friends.Another challenge is the fact that some cultures consider gift giving as okay. For instance, in Japan gift-giving can be an important part of conducting business. But in the United States gift giving is considered to be a bribe. That is, "an attempt to influence an individual's business decisions."(pg.319) In fact, these cultural differences can be challenging. So it is important that managers be discreet and wise when dealing with other cultures. Their goal should be of making it a positive experience instead of tense and nonproductive.According to this chapter, if a company is doing business abroad, the company needs to develop guidelines and policies for their employees. Some of these guidelines...

Read articals and answer in discussion - Assignment Example Information Systems have the capacity to distinguish the performance of an organization from another. There are areas of information technology that have not been explored and fully exhausted. For example, the area of data mining, artificial intelligence and robotics, decision support system and system automation. In the dynamic business world, there are newly emerging needs of information technology that continues to raise the new needs of information System solutions. For example, the present business world requires real time systems such as mobile applications. The demand for new data communication methodologies is continuously rising and their efficiencies place organizations in different ranks (Dychà © 10). The third rule for IT management is right. IT managers should place more emphasis on the vulnerability as opposed to the opportunities that it offers. There reason for this is that IT already has a guarantee of opportunities, so there is no need of wasting efforts searching for them. Secondly, Information Technology faces unpredictable threats that can be extremely costly. IT systems should be able to take care of information within an organization and guard them from external malicious attacks. There is especially an emerging trend of cyber crime threat against Information System Solutions. This is what should worry an organization. In fact, for as long as the system is exposed to vulnerability, even the opportunities do not serve any purpose to the organization. Information Systems Risk management is an essential function that an organization cannot do without unless it is planning to remain at risk of attacks. The management of an organization must therefore have a method of iden tifying possible risks, their causes and possible controls to put in place to regulate the exposure of sensitive data to external entities. There should be a continuous review of the risks to identify the most critical dangers that the

Mold making requires machines for mold welding, gridding and peening, and a lathe machine. Molds are used over and over till they wear out and fail to produce the required dimensional accuracy. After each, shift, the mold has to be replaced and maintained. The internal surface of the mold has to be ground using a sand wheel to remove any rust. The mold is then dotted with peening head to increase its crack resistance, and to improve its adhesion properties. All cracks on the internal surface of a mold have to be removed through turning, after which the turned area is welded and excess metal turned again to maintain the required dimensional controls. Grinding and peening ensure the mold finally has a smooth surface and is free from any cracks that may impair its usability. 2.2 Molten iron Preparation Molten iron, scrap steel, alloy and any rejected pipes are melted at this stage. The melting equipment is a two and three

Feminist View In Nuclear Discourse - Essay Example This paper tresses that the use of the feminist perspective and feminist view implies that the discussions of nuclear weapons and weapons of mass discussions has normalised and presented nuclear weapons in the daily vocabulary and discussion of nuclear weapons in the general and everyday sense. The research indicates that gender is a fundamental matter and situation in discussions about nuclear discourse. This is because the role of feminist views and feminist discourse is steeped in the need to break down male domination in the society in order to create a system in which women and children are fairly included. The use of nuclear weapons emerged at a time where men dominated the military terrain and hence, most of the views and ideas relating to nuclear weapons are fundamentally masculine rather than feminist. Therefore, the growth and expansion of nuclear weapons and the nuclear discourse has encompassed numerous conflicts relating to masculine and feminist views. Through the masculinist and feminist discourse, there have been numerous modifications and changes in the systems and processes of viewing and conceiving nuclear weapons. The first aspect is that feminist perspective acts as a general check to views and opinions presented on nuclear weapons. Secondly, feminist consideration for the impact of nuclear weapons on women and children as well as future generations plays a central role in the definition of women in society. Thirdly, the sacredness of military usage for nuclear weapons have been replaced by viewing nuclear weapons from a lighter, entertainment-based method and approach of viewing nuclear weapons.

Effect of the World Wars on Canada Essay Example | Topics and Well Written Essays - 1500 words

Effect of the World Wars on Canada - Essay Example Social Impacts of First and Second World War: Canada has been put into form by wars more than anyone could have realized it. The wars created the modern Canada, removing all kinds of traditions and memories of a â€Å"divided national identity†. Attitude of Canadians towards war was based on historical experience (Morton, 1999, pp. ix-x). The First World War had led to overwhelming changes in the social structure of Canada. The sacrifices and compromises that the average Canadians had to make called for new social order intending for emergence of peace. Groups of labor, women, farmers, churches and political parties all had developed their plans and programs for bringing in changes (Guest, 1997, pp. 49-50) Several social reforms were stimulated by the war. Pension issues, healthcare were some areas which were given special attention. In the field of social welfare, the profession of social work emerged out of liberal individualism. However keeping problems of divided jurisdiction at one side, the administrative problems aggravated by federal government’s failure to contribute to costs. Unemployment relief policy was largely developed at the municipal level, resulting in administrative procedures and policies differing from place to place with absence of standards in the level of aids (Guest, 1997, pp.50-85). Thus impacts of the war could be felt. As it can be understood that War and Society has a deep rooted connection and hence greater impacts are bound to occur on the societal issues when such World War affects or impacts countries individually (Keshen & Durflinger, 2007). However, as in the case of Canada, the effects have not been negative completely. The Second World War to o had a reflective effect on the social structure of Canada. The most rigorous crisis of unemployment got ended and the standards of living were raised for a large number of people in Canada. More significantly, the process of â€Å"industrialization† and â€Å"urbanization† progressed with greater rapidity. Production capacity of industries was stretched and superiority and intricacy of industrial processes also increased. The war had an overwhelming effect on the federal government as a whole. It became one of the largest employers of labor. The war saw several women responding to convene of the war and shedding their homemakers’ role to join the labor force. However with respect to Fordist estimates, the white male enjoyed better privileges than the women. Many women from Poland were brought into Canada and they represented the modern and educated women folk of tomorrow. Unemployment of the country decreased, and personal income and provincial income started increasing (Sangster, 2007, p. 472). As the war had ended with a sound financial form, even problems of agricultural surpluses also were removed. There was also a realization among the governments that social services were not only a luxury, but a crucial item in the smooth functioning during wartimes (Guest, 1997, pp.103-104; Francis, Jones, and Smith, 2007). Thus comparing the effects of the two world wars, it can be seen that the Second World War had bigger positive social impacts on the country. Political Impacts of First and Second World War: The political impact of the First World War formed or enlarged some divisions in the community. Before the year 1914, Canadians who resided in the western region of Canada had to consume products by paying much higher prices than those who were living in the country’s central and eastern regions. Price gaps also existed in the provinces that were existent for long times. By the year 1920s, the western and the eastern regions had div ided in terms of prices. According to sources, inflation was prevailing during and after the war, which led to high price ranges on consumable

Genetics and breast cancer Research Paper Example | Topics and Well Written Essays - 2500 words

Genetics and breast cancer - Research Paper Example Treatment plans have modified from time to time with the aim to conserve as much as normal breast tissue and reduce the recurrence rates. Different strategies have evolved ranging from modified radical mastectomy to radiation to hormonal and chemotherapy. Having a varied prognosis depending on the histo pathological appearance as well as the grading, staging and receptor status of the breast carcinoma. Early diagnosis and treatment yields better results, while late diagnosis and treatment results in widespread disease. Breast cancer one of the most common and ancient carcinoma in female occurring most commonly in postmenopausal woman and in individuals with BRCA mutation. The screening, diagnosis and treatment are rapidly changing areas with more and more advances in the diagnostic tests and resulting specific therapies depending on the histo-pathological and bio-markers. From diagnosis to treatment it needs a multidisciplinary approach with physicians, radiologists, oncologists, histo-pathologists on board. This article focuses on the etiological factors, genetic mutation, diagnosis, treatment plans and prognostic factors. . Breast cancers being more common in women but can also occur in men and have a poor prognosis as in men there is always delay in diagnosis as opposed to women. Unlike other carcinomas it can be picked up early as it presents with a lump in the breast, for the same reason it has also been documented as an ancient disease as unlike other carcinomas it could become visible and c ould be picked up as a lump in breast. If we look at the above risk factors, most of them can be explained by the fact that excessive exposure to sex hormones can lead to breast cancers. Early onset of menses and late menopause, both of these cases leads to over exposure to sex hormones (same can be explained with obesity). One of the studies being carried out concluded that

How Was Vietnam Sexual Bias Essay Example for Free

How Was Vietnam Sexual Bias Essay People have long suffered because of their sexual orientation, but the increasing frequency and severity of this problem only recently gained the attention of the United Nations. Human rights violations based on sexual orientation and gender identity encompasses violence, cruelty, discrimination, and other acts of hatred based on real or perceived sexual orientation or gender identity. Sexual orientation is defined as ―each person‘s capacity for profound emotional, affectional and sexual attraction to, and intimate and sexual relations with, individuals of a different gender or of the same gender or of more than one gender. Gender identity refers to ―deeply felt internal and individual experience of gender, which may or may not correspond to the sex assigned at birth, including the personal sense of the body (which may involve, if freely chosen, modification of bodily appearance or function by medical, surgical or other means) and other expressions of gender, including dress, speech and mannerisms. Violations of sexual minorities are manifested in two ways: 1) physical harm resulting from murder, kidnapping, sexual assault or other forms of violence and 2) unfair treatment, deprivation of liberty, and discrimination exercised on personal and institutional levels. The aspect of physical harm is more frequently noted by the media, but many cases go unreported and without the attention that is needed to curb their prevalence. Special rapporteurs from the UN found previously unnoted examples that show the gravity of these issues. A period of violence specifically targeting members of lesbian, gay, bi-sexual, and transgender (LGBT) groups in Honduras resulted in the brutal killings of 21 people in 2010. One of these victims was ―found dead in a ditch, her body beaten and burned, showing evidence of rape and blows to her face from stoning so severe as to render the remains virtually unrecognizable. In other parts of the world, transsexual women have been beaten in the breasts and cheekbones to intentionally burst implants and release painful toxins in their bodies. Four people were seriously attacked in Uganda and many were forced to hide when a local paper published the photos of 100 people it said were homosexuals and encouraged people to ―hang them. There‘s a cultural contribution to the prevalence of this violence, too. More than 5,000 honor killings take place each year to punish people who do not remain true to cultural expectations. An increasing number of these victims are killed because of their sexual orientation or gender identity. This is seen in the 2009 Iraq killing campaign that tortured and murdered hundreds of LGBT members on the basis of protecting society from the ―third sex. Killings also take place by victims‘ relatives to preserve their family‘s honor. Cultural myths such as homosexuality being a disease or that lesbian women‘s sexual orientation will change if they are raped by a man are also dangerous elements of this problem. Though physical violence based on sexual orientation and gender equality is a pressing issue, attention must also be given to the second aspect of this topic. Discrimination and unfair treatment based on sexual orientation date back to the religious laws of the Bible and other holy books. Napoleon temporarily established laws decriminalizing homosexuality as part of his penal code in 1791, but long-term protection did not take place until Denmark repealed its similar laws in 1933. Almost all other countries have followed Denmark‘s example since then except for those in the Middle East (save for Israel), North Africa, and the former British colonies in Africa, the Caribbean, and South Asia. These latter countries are the most common (but not exclusive) context in which LGBT members are deprived of their liberty in areas of ―judicial prosecution and trial, administrative detention, deprivation of liberty on medical grounds and arrest for the purposes of harassment, among o thers. Even countries that have repealed these laws can foster unfair treatment stemming from sexual orientation because of their inability to better protect victims. Cases of discrimination based on sexual orientation are vastly underreported, but several examples exist that illustrate its solemn presence in the life of people of all ages. According to a 2007 study, up to 40 percent of homeless youth were turned away from their homes and charitable shelters because of their sexual orientation or gender identity. LGBT students are often the targets of violence, harassment, and other forms of bullying while in high school and college. In addition to the physical harm that results, many victims struggle with emotional consequences such as depression and low self-esteem. A 2010 report on prison conditions in Greece revealed that ―detainees in a lesbian, gay and transgender section of a prison were reportedly denied access to an outside yard for two years, confined to their cells and a corridor at all times. Striving to address these forms of discrimination and unfair treatment, the Human Rights Committee (HRC) affirmed that its regard to ―equal and effective protection against discrimination on any ground such as race, color, sex, language, religion, political or other opinion, national or social origin, property, birth or other statusâ€â€" in Article 26 of the ICCPR extends to discrimination on grounds of sexual orientation. Even so, the lack of response from Honduras, Greece, and other countries in which similar atrocities occur demonstrates that nations have not fully adopted the HRC‘s concern on the issue. Without the creation and observation of standard operating procedures that guide law enforcement to handling these issue seriously and responding properly to violations that occur, these countries are unable to progress toward a greater solution. There have been several emergences of human rights violations based on sexual orientation and gender identity in recent world events. In March 2012, a gay man died after being attacked by a group of neo-Nazis at a park in Chile. The perpetrators tortured the man for an hour by carving swastikas in his body and otherwise mutilating him. His death brought renewed efforts by the UN and human rights organizations to call attention to the mistreatment of sexual minorities and the need for harsher penalties for hate crimes. Another example was seen that same month in a different arena when Muslim delegates protested legitimizing homosexuality by walking out of the first UN Human Rights Council debate on gay rights. Without these nations‘ support, the problems will persist and further metastasize. Past UN Action: The UN has made efforts to ensure that the issues of sexual orientation and gender identity are given equal attention to all other areas of human rights violations. In 2007, the International Commission of Jurists‘ discussion on the inclusion of sexual minorities in human rights protection resulted in the ―Yogyakarta Principles on the Application of International Human Rights Law in Relation to Sexual Orientation and Gender Identity. This document served as the foundation for later work by the OAS (AG/RES. 2435) and the UN‘s first resolution (A/HRC/17/L.9/Rev.1) concerning LGBT rights. The UN‘s resolution affirms that violations based on sexual orientation or gender identity are matters of human rights, and it calls for a report on related cases of violence and discrimination. The report (A/HRC/19/41) was published in November 2011 and accounts for unprecedented levels of violence and injustice shown toward sexual minorities. Most recently, th e UN reiterated its deep concern of violence based on sexual orientation and urged member nations to prioritize its reduction and elimination. Problems and Possible Solutions: Researchers fear that the majority of violations go unreported due to the shame of the victim or the apathy of the law and legal systems in some countries. Real action most often takes place when international attention is drawn by a death caused by hate crimes based on sexual orientation or gender identity. There may be no better solution for this problem than to increase international pressure on countries to curb the rate of crimes committed against LGBT members. If a sense of national pride for reducing the crime rate could be established – and a strong sense of shame if the rate remained the same or deteriorates – then a solution to this issue would be more effective and more sustainable. Questions to Consider as you Prepare: * Which should efforts for change focus on: law or education? Who should enact these changes and where would funding originate? * Is there one general solution to this problem or is it region-specific? If solutions are region-specific, how could resolutions be tailored to meet the problems of multiple regions? Who would determine what each regional problem requires to be eliminated? * How can the reporting of crimes based on sexual orientation be improved? How can international actors help without posing a risk to nations‘ sovereignty? * With many crimes occurring within prisons, how can LGBT members be better protected? Is there a way to do this without incurring significant expenses?

The Process of Fermentation

The Process of Fermentation Background research Fermentation is a process carried out by many microorganisms and which produces a variety of useful compounds and this reaction is very important in industry for baking and brewing. In fermentation, carbon dioxide gas bubbles out of the solution into the air leaving a mixture of ethanol and water. Ethanol can be separated from the mixture by fractional distillation. Fermentation must be carried out in the absence of air to make alcohol. If air is present, ethanoic acid is made instead of alcohol. This reaction is very important in industry for baking and brewing. Yeast, is most commonly used in baking to break glucose, or other sugars to produce different products. In baking and brewing different type of yeast is used. An enzyme called invertase will convert a sugar called sucrose into smaller sugar molecules called glucose and fructose. Glucose is fermented by the yeast to ethanol and carbon dioxide. The released carbon dioxide causes dough to rise and to hold it high. The produced alcohol contributes to the breads flavour. The optimal temperature for yeast to ferment sugar is 32 °C. In warmer temperature (45  °C) the yeast cells will die. Also fructose and sucrose care used by the yeast as fermentation substrates. Sucrose is directly transformed by an enzyme called invertase, into glucose and fructose. Sucrose is a good substrate for fermentation. When sucrose or glucose is added to the dough, they are faster fermented than maltose. Sugars are small molecules which belong to the class of carbohydrates. As the name implies, a carbohydrate is a molecule whose molecular formula can be expressed in terms of just carbon and water. For example, glucose has the formula C6(H2O)6 and sucrose has the formula C6(H2O)11. More complex carbohydrates such as starch and cellulose are polymers of glucose. The difference between a monosaccharide and a disaccharide can be seen in the following example: How do enzymes work? Enzymes speeds up the biochemical reactions and they work best at an optimum temperature, however if the temperature has increased it will provide more kinetic energy to the molecules involved. Therefore the number of collisions between enzyme and substrate will increase as well as the rate of reaction. If temperature rises above the optimum the enzymes will be denatured. The bonds which are holding the structure together will break and the active sites lose their shape and will no longer react.

There are two different types of sugars that I am going to which are monosaccharide and disaccharide sugars. Introduction Respiration is the release of energy from glucose or another organic chemical. The chemical energy in glucose can be used to provide the energy required for growth, repair and movement. This is a controlled process that occurs in small steps and each step requires respiratory enzymes. These enzymes allow the process to take place at body temperature 37C °.m Aerobic Respiration is the normal form of respiration. It requires oxygen and releases the most energy from glucose. This form of respiration occurs within the mitochondria. Glucose + Oxygen = Carbon Dioxide + Water + Energy C6H12O6 + O2 = CO2+H2O + Energy However, it is possible for respiration to take place without oxygen in a process known as anaerobic respiration. It also releases energy from glucose but not as much. When yeast respires anaerobically it produces carbon dioxide and alcohol. When we respire we produce lactic acid. Too much lactic acid causes fatigue to our muscles. Yeast produces ethanol (alcohol) when it respires anaerobically and ultimately the ethanol will kill the yeast. We can respire in both ways too. Normally we use oxygen, but when we are exercising, we may not get enough oxygen into our blood, so our muscles start to respire anaerobically. Word equation for anaerobic respiration: Glucose lactic acid + Energy C6H12O6 2C3H6O3 + Energy Sugars can be categorized as either simple or complex depending on their chemical structure, in other words the number of saccharides (glucids) they are composed of such as: Monosaccharide Are the most basic unit of carbohydrates and they are the simplest form of sugar. Examples of monosaccharide include glucose, fructose , and galactose. Monosaccharides are the building blocks of disaccharides such as sucrose and polysaccharides (such as cellulose and starch). Disaccharide Two monosaccharide joined together by a glycosidic linkage is called a double sugar or disaccharide. The most common disaccharide is sucrose. It is composed of glucose and fructose. Sucrose is commonly used by plants to transport sugar from one part of the plant to another. Polysaccharide Polysaccharides are polymericcarbohydrate structures, formed of repeating units joined together by glycosidic bonds. These structures are often linear, but may contain various degrees of branching. When all the monosaccharide in a polysaccharide is the same type the polysaccharide is called a homo polysaccharide, but when more than one type of monosaccharide is present they are called hetero polysaccharides. http://www.polypeptide-polysaccharide.com/ Hypothesis I hypothesise that glucose sugar which is a monosaccharide will have a greater rate of fermentation than sucrose which a disaccharide sugar. Justification There are different types of sugars that have different effects on the replication of yeast, which would have an effect on the rate of fermentation. Therefore, I am going to investigate the main two sugars (Monosaccharide and disaccharides) to check which type of sugar will have a greater rate of fermentation. Monosaccharides are simple sugars made of 1 molecule of sugar whereas disaccharides are complex sugars made of two molecule of sugar. So, my hypothesis would be that glucose will increase the rate of fermentation than sucrose because glucose is a monosaccharide sugar and therefore has one unit of sugar. This will enable the enzymes in the yeast to break down the bonds of the simple sugar very easily with less energy, and short period of time. Whereas sucrose has two unit of sugars and therefore has twice as much bonds as glucose sugar which will slow down the enzymes action in breaking down the bonds, as it requires more energy with longer period of time to break down the bonds. So, in order to check whether my hypothesis is right or wrong, I will need to perform the experiment by testing the main two sugars glucose (Monosaccharide) and sucrose (disaccharides). Experimental method In the experimental method I have decided to use the technique of titration. A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. So in this experiment, I am going to use the titration technique to find out which type of sugar will produce a greater rate of fermentation. Typically, the titrant is added from a burette to a known quantity of the analyte (the unknown solution) until the reaction is complete. Knowing the volume of titrant added allows the determination of the concentration of the unknown. Often, an indicator is used to usually signal the end of the reaction, the endpoint. http://www.science.uwaterloo.ca/~cchieh/cact/c123/titratn.html Here are some important apparatus that are important to carry out the titration method: * Burette: The burettes are mainly used for titrations to deliver one reactant until the precise end point of the reaction is reached. Burette used to measure the volume of a solution accurately which can be read to an accuracy of half a division that is to 0.05 cm3.  · Conical flask, beaker: The conical flasks, beakers are used for mixing, reactant and transporting but not for accurate measurements. The volume stamped on the sides of the conical flask and beaker is approximate and accurate to within 5%. * Pipette: Pipettes are used to measure small amounts of solution very accurately and it has a bulb to draw the solution into the pipette. It transfers 25 cm3 (usually to  ±0.05 cm3) of a solution into a conical flask. * Funnel: is a pipe with a wide, often conical mouth and a narrow stem (this will be needed to make sure the transferring of the sodium hydroxide into the burette in smooth and safe as possible). * 0.1M of sodium hydroxide: will be used as the solution in the burette which will indicate the amount of alkali that is needed to neutralize the acid in the fermented solution. * Phenolphthalein indicating solution: this indicator solution will help us see when the solution in the conical flask changes, it is very important that we use the same amount of drops on both solutions this will help us get an accurate colour change result. Apparatus: * 2 g dried brewers yeast. * 200cm 0.2 M fructose. * 200cm 0.2 M lactose. * 2 x 0.5 g ammonium phosphate. * 2 x 0.5 g ammonium sulphate. * 3 x 250cm wide necked conical flask. * 2 x silicone rubber bung with two holes. * 3 x glass fermentation lock. * 3 x 15cm bent glass pipette with 3cm rubber tubing. * 3 x restriction clip (Hoffman clip). * 3 x glass rod. * 50cm burette. * 3 x pipettes. * 0.1 M sodium hydroxide solution (about 400cm). * Phenolphthalein indicator solution and dropping pipette. Procedure for day 1: 1. Label two 250cm flask: fructose and lactose and control (water). Add 200cm of 0.2 M sugar solution to the named flasks and 200cm of water to the control flask. 2. Add 2 g of dried brewers yeast and then 1 g of ammonium salts to each flask (0.5 g each of ammonium phosphate and ammonium sulphate). 3. Ensure that the yeast is respuspended and the salts are dissolved in the sugar solution by carefully stirring each solution with a different glass rod. 4. Carefully and firmly insert the fermentation lock and bent pipette into the silicone rubber bungs. 5. place the bungs firmly into the neck of the flasks To assist the fermentation the flask should be placed in an incubator (15 20 C). Procedure for day 2: 1. Set up a burette containing 0.1 M sodium hydroxide solution. 2. Swirl the flask to ensure a homogenous mix of culture and remove a total of 25cm of sample (10cm + 15cm). 3. Place the removal sample into a small flask and add two or three drops of phenolphthalein solution. 4. Plot a histogram of the volume of the alkali used to neutralize each sugar solution. The histogram can be used to indicate the extent of fermentation. Justifying day one procedure: There are few things that can affect the preparation of the solutions which are usually known as a potential errors and these error can come from: Weighing balance: we used the 2 decimal place balance to weigh our samples and I think the weighing of the sample would not be reliable as it measures to 2 decimal places. In this case our results might be unreliable because we cannot determine whether it is the exact weight of the sample we are measuring. For example if we weighed out 3g of yeast on the 2 decimal place balance it would only show 3.00g, whereas if we used another balancer which measures the sample to an accuracy of 4 decimal places it would have been better because it would give us 3.0000g. Stirring rod: depending on the pace of stirring the solution if we didnt use the stirring rod gently and frequently it would affect the solubility of the sample that we are making, this is because sometimes we may think that all the solid part in a solution are fully dissolved in the sample. However, sometimes a small amount of the solid may not dissolve properly without noticing it. Therefore, it is very important that we had to stir the solution gently and frequently so that the entire solid are completely dissolved. Room temperature: leaving the solution to ferment over night the temperature of the room is not constant because at night the temperature decreases which would have an effect on the rate of reaction of the fermentation by slowing the reaction down. It would have been better if I could use a water bath so we can take a full control of the temperature and also make it constant. Duration for fermentation: the duration that was provided for fermentation was not enough for the yeast to ferment, if the solution was left for longer period time the sample might have fermented better and also if would have left the solution for longer night probably 2 to 3 nights it would have been better too. However, leaving the samples for more than 4 to 6 nights could affect the rate of fermentation because the longer we leave a sample the more contaminated the sample may get by bacteria. Justifying the procedure of day 2: In day 2 we have used the technique of titration to find out which type of sugar will produce a greater rate of fermentation. However, the manual titration technique is not as accurate as it is industries. The titration technique is carried more accurately on an industrial scales because of the automated machines that are used are automated which carry out the titration in a more accurate way and more than one sample at a time. The titration method: the method only allows us to do one titration at once which was not suitable for our time scale. We were using two burettes one for each solution but we still had to run one burette at a time. Time: I think the period of the titration was not sufficient because we had to carry out three titrations and three repeats for each type of sugar including the control, keeping in mind that we had to record the all values accurately from the titration. Therefore, we would rush in the experiment to finish all the titrations as quickly as we possibly can, so we would not carry out the investigation in an appropriate way which could affect our overall result. Recording the results and how many repeats will be performed In this investigation I will be using two types of sugars which are glucose and sucrose and a control which is water. For each type of sugar including the control I will make 3 repeats so that I can get an average result of the volume of the sodium hydroxide which has been used. I would perform a rough titration for each sugar to help me to decide approximately where the end point is going to be and how much volume of the sodium hydroxide will I need to neutralise the solution that I am testing Type Titre1 Cm ³ Titre2 Cm ³ Titre3 Cm ³ Average Cm ³ Glucose 22.65 34.85 25.90 27.80 Sucrose 52.00 40.45 40.750 46.73 Control 8.15 17.60 8.15 11.30 Once I have completed the experiment and recorded my results accurately to two decimal places, then I will work the average result for both sugars and the control for example, for glucose sugar I would add the results that I have obtained including the rough one and then divide the answer by three. Once I have calculated the average result for both sugars and the control, then I would plot a graph to show the volume of sodium hydroxide that has been used to neutralise each solution which will help to compare which type of sugar fermented better. Titration results Conclusion from the results During the titration process I kept watching for the colour of the solution we were titrating to change from cloudy white solution to a light pink colour. The light pink colour indicate that that neutralisation of the solution we are tittering is completed which known as the end point. Looking at this table it shows that sucrose has a greater rate of fermentation than glucose because it has a higher titre of sodium hydroxide that was needed to neutralise the solution. Therefore, this indicates that sucrose was more acidic and more CO2 dissolved in the sample that we were testing and also more fermentation rating took place. Accuracy of procedure and each piece of equipment used Each piece of equipment we have used, we take the volumes reading from the bottom of the meniscus. Burette used to measure the volume of a solution accurately which can be read to an accuracy of half a division that is to 0.05 cm3. * Rinse equipments before use: We have used distilled water to rinse the equipment before we carry out our investigation because the equipment may not washed properly so it contains other solutions which would make our results unreliable. By rinsing the equipment before using them, would decrease the possibility of getting of contamination. * Labelling equipments: We had to label the conical flasks to ensure that the right sugar is in its labelled conical flask because sugars look the same so labelling conical flasks would help us identify the solution quickly without getting mixed up of which sugar belongs to which flask . * Ammonium salt: As we know that yeast gets food from the surroundings and therefore, we have used the ammonium salt and ammonium phosphate is to feed the yeast with nutrient as ammonia contributes to nutritional needs of such organism.  · Using room temperature for fermentation: Because enzymes within yeast are from different habitats therefore using different temperatures for each type of sugar would affect the fermentation process. Therefore we decided to use room temperature as it is suitable for both types of sugar and the yeast in which perform the fermentation process.  · Swirling flasks: It is very important that we had to swirl the flasks properly before taking the samples out because it would help ensure that all the solids are fully dissolved in the solution and becomes complete solution.  · Using pipette filler to take the samples: we would be using pipette filler because it is good equipment for taking around 25cm3 of the solution.  · Phenolphthalein indicator: We have used this indicator solution to help us to see when the solution in the conical flask changes, so we had to use the same amount of drops on both solutions so that we get an accurate colour change result. Evaluation: The reliability and the accuracy of the investigation: It is very important that we had to follow all the instructions carefully that were provided to us because it would help us work more accurately and get better result on our experiment. However, we would not expect to get the same results for each repeat of titration, because it depends on determining the end point of the reaction. For example, the cloudy white colour is quite similar to the light pink colour therefore; sometimes it is difficult to determine whether the exact end point has been achieved or not , and so we wouldnt expect to get the same results for each time we repeat the experiment. As a result, it would be better to hold the solution up to the light to help us determine the exact end which is the light pink colur in the same range. As we know that yeasts perform better under anaerobic conditions, so if oxygen got into the solution then the condition inside the conical flask will change to aerobic and the process of fermentation will not take place. As a result, we had to ensure that the process is taking place with the absence of oxygen conditions, so we ensured that the bung was firmly fastened into the conical flask that contained the fermenting solution. It was very important that that the bung was fastened otherwise the air that came from the surrounding would affect the yeast respiration by getting into the conical flask to the solution that we were fermenting. Moreover, if the bung is not fastened properly then carbon dioxide will leak from the conical flask would affect on the acidity of the solution because the sodium hydroxide needs to be titrated with an acidic substance so to achieve neutralisation of the solution in the flask. Therefore, keeping the bung fastened will keep the process of fermentation under anaerobic condition. When the samples had been left to ferment overnight, bubbles were produced on the top of the solution because the bubbles were formed from the carbon dioxide gas being given off from the reaction in the solution. This may have an effect on the measurement of the solution in both the pipettes and burettes because the solution must be measured from its meniscus. Therefore we have got to be careful while taking the reading of the solution to take from the meniscus which is the curve at the top of the liquid if did so we would get more accurate and reliable results. There is another factor which can make our investigation unreliable which the temperature. This can have a major effect on the rate of fermentation because enzymes are very sensitive to temperature. Enzymes speeds up the biochemical reactions and they work best at an optimum temperature, however if the temperature has increased it will provide more kinetic energy to the molecules involved. Therefore the number of collisions between enzyme and substrate will increase as well as the rate of reaction. If temperature rises above the optimum the enzymes will be denatured. The bonds which are holding the structure together will break and the active sites lose their shape and will no longer react. There are some factors in which can have an effect on our overall result such as, room temperature, weighing and the concentration of the samples. So Now I going to make a table to show the variables, the effects they may affect the investigation and how they can be controlled during the experiment to get more accurate and reliable data. Controls and variables during this experiment: Variables The effects on the experiment How could it be controlled Room temperature As we know the room temperature is not constant therefore it would affect the enzymes action during the process of fermentation We could have made the temperature constant if we placed the samples inside an incubator which will help the enzymes work better. Weighing Another factor that could affect our overall result is that being very close to the weighing balancer while we are weighing our samples because breathing on the balancer changes the reading of the sample In order to optimise the effects of the air on the weighing balancer while we are taking the reading of the sample is to use an accurate weighing balancer which is surrounded by glass frame and gives the reading of the sample to four decimal places. Concentration of sample If we used the wrong concentration of the sugars, this would affect on our results. In order to make sure that we are using the right concentration we have look carefully at the labels of the solutions which indicates the name of the solution and its concentration.

My Philosophy of Education :: Philosophy of Teaching Statement

Philosophy of Education The single word â€Å"teacher† does the profession no service. A teacher is really a combination of the most important professions in the world: doctor, mother, philosopher, motivational speaker, scientist, counselor, and so much more. Besides the parents, an educator is the biggest influence in a child’s life. The age span in which children are in school is the most impressionable years of their lives. A student’s educational experience can mold the events of his or her future. That is why I want to become a teacher. I want to be a mold for younger generations, and I hope for students to remember a knowledgeable and ethical teacher. The overall purpose of education is to provide the knowledge and some of the experience that a student needs to survive today. The world is harsh and fast-paced for newly graduated young adults to enter blindly. All the student has to take is the educational background that he or she has been provided. It is imperative that critical thinking and problem-solving strategies are taught. In this way, I am a Progressivist. I believe education should be relevant to the future and to life in general. Decision-making is a hard task for even the most experienced. A young adult leaving home for that first time has no idea what decisions to make. Educators should teach students about life applications such as: cooking simple foods, changing a tire, or balancing a checkbook. I also hold an Essentialist idea of the classroom. I want to be the authority figure and I want the respect of the children. I not only want it for myself, but for other adults also. Children need to b e taught to respect others and to show general consideration. It seems like this type of teaching has been left out of learning programs and now even young children are involved in fights at school. I believe knowledge is relative—dependent upon person, place, and time. This is why I also believe that the role of the teacher is so important. Children learn by example and are extremely impressionable.
