...and “Once Brothers” The two films I will be reflecting on is “Paradise Now” and “Once Brothers.” “Paradise Now” tells the story of two childhood friends from the West Bank who are recruited to participate in a suicide bombing in Tel Aviv which is one of Israel’s biggest cities. Whereas “Once Brothers” tells the story of Yugoslavian basketball players who played on the Yugoslavian national basketball team and eventually were recruited to play on different NBA teams in the United States. The common theme between the two films were the identity politics during the Arab-Israeli conflict and the former Yugoslavian conflict after the disintegation of the Soviet Union. The Arab- Israeli conflict...

...for “totally” and “cray” (or “cray-cray”) for “crazy.” What accounts for the meteoric rise of YOLO, and how has it gone virtually unnoticed by nonmillennials? Its appeal to the youthful is self-evident. YOLO as a shorthand mantra defines youth, on a certain level. What is teenagehood if not the adventurous, often foolhardy, desire to test the limits of acceptable behavior—because hey, why not? YOLO! The carpe diem sentiment of “you only live once” has a long history predating its punchy acronymic clipping. Garson O’Toole, on his Quote Investigator blog, traces variations on the theme back to the 18th century, as in this line from Samuel Richardson’s novel “Clarissa”: “We live but once in this world; and when gone, are gone from it for ever.” The exact wording of “you only live once” begins cropping up in the late 19th century, and by 1937 it was popular enough to be used as the title of a Fritz Lang film noir. One wry elaboration, credited to the comedian Joe E. Lewis in 1952, is “You only live once, but if you work it right, once is enough.” Today’s young purveyors of YOLO do indeed appear to be trying to work it right, though what that means is up for debate. Eble’s students illustrate its typical use, as a carefree tag to explain an impulsive choice: “You want to park illegally in this spot? YOLO!” “Should I buy these shoes or pay rent? YOLO!” The word has also found favor as a verb, as in this Yelp review of a Jersey City pizzeria: “All the times I come home after a...

...Arctic Mining Consultants (Case Study) Tom Parker enjoyed working outdoors. At various times in the past, he worked as a ranch hand, high steel rigger, headstone installer, prospector, and geological field technician. Now 43, Parker is a geological field technician and field coordinator with Arctic Mining Consultants. He has specialized knowledge and experience in all nontechnical aspects of mineral exploration, including claim staking, line cutting and grid installation, soil sampling, prospecting, and trenching. He is responsible for hiring, training, and supervising field assistants for all of Arctic Mining Consultants' programs. Field assistants are paid a fairly low daily wage (no matter how long they work, which may be up to 12 hours or more) but are provided meals and accommodation. Many of the programs are operated by a project manager who reports to Parker. Parker sometimes acts as a project manager , as he did on a job that involved staking 15 claims near Eagle Lake, Alaska. He selected John Talbot, Greg Boyce, and Brian Millar, all of whom had previously worked with Parker, as the field assistants. To stake a claim, the project team marks a line with flagging tape and blazes along the perimeter of the claim, cutting a claim post every 500 yards (called a length). The 15 claims would require almost 60 miles of line in total. Parker had budgeted seven days (plus mobilization and demobilization) to complete the job. This meant that each of the four stakers (Parker, Talbot...

...Lessons from Lehman Brothers: Will We Ever Learn? Steven Figueroa, Adrian Bland, Victoria Fabuluje, Amy Ramkey, Carmen M. Ortiz MGT/521 03/10/14 CHRISTINE GNIEDZIEJKA Lessons from Lehman Brothers: Will We Ever Learn? 2. What was the culture at Lehman Brothers like? How did this culture contribute to the company's downfall? Anyone knows that rewarding bad or illegal behavior can lead to the making of a person who is irresponsible and reckless. This is a general description of the type of employees involved in the Lehman Brothers company culture. The Lehman Brothers culture was out of control and a blind eye was turned to any high risk deals and or illegal modifications done to the company balance sheet. Many failed or wrong decisions made by management often went without consequence. In fact, individuals making any high risk or questionable deals were treated like superstars or moneymakers rather than irresponsible or uncalculated decision makers. This type of reward system can only draw the attention of the greedy and crooked minded. The type of culture created was a recipe of disaster for the Lehman Brothers company. There were some employees that did not agree with many of the choices made by upper management. But, when they attempted to voice their opinion or concerns they were ignored and overruled leaving them no choice but to follow suit. By ignoring any standards, ethics or controls to guide the Lehman Brothers culture the employees were left to express their...

... Lehman Brothers is no more. Merrill Lynch has gone down the Bank of America maw. AIG too could go belly up. With a doubt, these developments in America are the most shocking events to have hit global financial markets. So where did it all begin? And what does it mean for the Indian stock markets? Find out. . . What is (or was) Lehman Brothers? America's fourth-largest investment bank Lehman Brothers Holdings Inc has filed the biggest bankruptcy petition known to mankind. The 158-year-old firm was founded by brothers Henry, Emanuel and Mayer Lehman, Jewish immigrants to the US from Germany, in 1850. Henry set up a general store in Alabama in 1844 and was later joined by his brothers. In 1850 they set up the merchant bank in New York after having made money in railway bonds. So what went wrong? Compiled by Rediff Business Desk Lehman Bros, which till June 2008 had not reported a quarterly loss even once, had earlier survived many an economic crises, like railroad bankruptcies of the 1800s, the Great Depression in the 1930s, and the collapse of Long-Term Capital Management in the 1990s. Thus the collapse of the giant investment bank came as a major shock for the entire world markets that plunged after Lehman filed a Chapter 11 petition with US Bankruptcy Court in Manhattan. The $613 billion (some estimates put the size at $639 billion) bankruptcy thus throws up the question: why did the Wall Street giant go bust? Here's why. . . Why did Lehman Brothers go bankrupt...

...problems come from yesterday's “solutions”. The first law of the 5th discipline can surely indicate the method for the acquired riches of the trading companies. Companies like Goldman Sachs and Lehman Brothers, had used undrhanded methods in their operations that assured them of easy wealth by fooling customers into taking unnecessary risks knowing fully well that once it blows over they not only goes unscathed but also profit from it by the default credit swaps from AIG. While this method was ingenious in a business point of view. It is clearly unethical. Although it did its job at that time of solving their problems on how to earn a big profit. It became a huge problem now that it caused the global recession. The harder you push the harder the system pushes you. When stock markets plummeted. It was pretty obvious to the rest of the world that the US is in a financial crisis. Lehman Brothers Trading Company was on the brink of bunkrupty and it was to everyone's best interest that they will be able to stabilize to prevent the inevitable crisis. However, no matter how much time, money and effort both the private and public sectors had invested in the matter. Lehman Brothers declared bunkrupty. And because of that, the rest of the company heavily affiliated with the Lehman Brothers took a pretty big blow in their financials as well. Behavior grows better before it grows worse. Everyone was able to share in the benefits while it was good but the story was clear when it showed...

...Lessons from Lehman Brothers: Will We Ever Learn? MGT 521 September 9, 2013 Introduction Lehman Brothers financial services filed bankruptcy on September 15, 2008, in the New York Southern District U.S. Bankruptcy Court. Resulting in an immediate 500 point drop in the Dow Jones (Did Ernst & Young Really Assist Financial Fraud? 2011). This day became known as ‘‘Dark Monday’’ (Donaldson, 2012). This was to date, the largest bankruptcy filing in history unleashing a “crisis of confidence that threw financial markets worldwide into turmoil, sparking the worst crisis since the Great Depression.” However this financial icon’s fall is no surprise. The bankruptcy examiner released reports saying that the firm’s executives and auditor, “lambasted” for what they did to cause the collapse of the firm (Robbins & Coulter, 2010). The Lehman Brother culture was one of risk and reward. At the company, “Excessive risk taking by employees was openly lauded and rewarded handsomely. Employees knew they could give risky ideas and they would get rewards for them. Individuals making questionable deals were hailed and treated as ‘conquering heroes’.” (Robbins & Coulter, 2010, pp. 147-148). If anyone would question decisions made or speak out in disagreement, executives would not listen. In addition, the executives would overrule and go with the least desirable decision. Most companies would be wary of taking so many risks and only give reward after that...

...George Orwell’s dystopian novel, “1984”, depicts a society of which the fictional symbol, Big Brother, is the totalitarian leader, and the single party controls everything. Big Brother and the party have instilled the idea that, “Who controls the past controls the future; who controls the present controls the past”, meaning that the past can be altered to one's desire, in this case to Big Brother’s. Winston, the protagonist of the novel, works at the Ministry of truth in the records department, where he, with many others, has to alter information from the past, in magazines and newspapers, so it always supports the party line, as Big Brother and the party must never be wrong. Unlike everyone else, brainwashed by the party, Winston realises...

... will have an effect on our entire lives. To achieve success we must follow our dreams overcome obstacles and not let the fear of failure interfere with our goals. A perfect example of how a dream leads to success is the Wright Brothers, Orville and Wilbur. They were the first innovators of flight and created the world’s first working airplane. When the brothers were young, they opened their own bike company to capitalize on the public’s new interest in bicycling. Once they earned enough money from their cycling company they wanted pursue their dreams of flying and flying machines. At first they tried to use gliders to fly, which worked but it wasn’t considered actually flying. A few years later they managed to put an engine on a plane and on December 17, 1903, they recorded the first flight. Although they had many critics, they proved all of them wrong when they flew publically in air shows. The two brothers had a dream that one day humans would take to the skies for transportation. Today most of their planes and equipment are scattered all over the country in different museums, including the Smithsonian. Wilbur and Orville Wright faced numerous hurdles that seemed impossible but they did not let challenges or failure deter them. The Wright brothers serve as an example of how hard work and dedication pays off in the end. There are many types of dreams; financial success is one, while another and more important is happiness and contentment. I have many goals that I hope will...

...world of facades and ignorance. Technology coats the society, from giant wall screens, to tiny radios that fit in your ear. People loathe books and thinking, and instant gratification is all the rage. People’s fiery hatred of books materializes itself in the form of literal fire in the hands of the firemen. Their primary objective involves burning books and any other form of taboo item. The captain of these firemen is a smart yet difficult man named Beatty. In 1984, a totalitarian government known as “Big Brother” dominates the society. Nothing you say or do is free, and the fear of constantly being watched hangs in the air. If someone even dares to think differently, the deadly thought police will catch, torture, and eventually kill them. The government fabricates everything, including the...

...Barclays Acquisition of Lehman Brothers Background Barclays PLC, one of the main saving banks in the United Kingdom, agreed Sept. 16, 2008, to purchase the volume of Lehman Brothers Inc. for $1.75 billion. It has acquired parts of Lehman's equities commerce in Europe and took on some Lehman workers in Asia. Lehman, the fourth major asset bank in the United States, was one of the victims of the subprime advance disaster that led to the administration stand security of Bear Stearns in March 2008 and the conquest of advance giants Fannie Mae and Freddie Mac by the U.S. Treasury in advance in September of 2007. Worth as much as $45 billion in early 2007, Lehman incurred almost $4 billion in losses in the third quarter has seen its stock worth fall down and was faced with disciplinary downgrades in its credit rating, which would have made it tremendously hard to raise much-needed capital. (Clark, 2008) Fuld who was the Head of Lehman sought Chapter 11 bankruptcy defense for Lehman on Sept. 15 2007 after U.S. Treasury Secretary Henry Paulson made it obvious that the administration would not spend any of taxpayers money to fund any of Lehman’s faulty asset. Under Chapter 11, which shields a corporation from creditors' lawsuits while it reorders its finances, Lehman became more attractive to Barclays; the British bank then bought Lehman's choicest bits devoid of assuming its more than US$600 billion in liabilities. Under the terms of the contract, which got approval from the insolvency...

...we are socialized, in other words. Expectations for a guy named Bubba or a woman named Shaquita are different than they are for people with the names Winston and Hillary. In other words people make assumptions about others base on their names. In Alice Hoffman’s novel Local Girls, the narrator plays with this idea of the interplay of destiny, socialization, and free will, symbolized by the names she gives the central characters. The character whose name is the most apparently burdening is Gretel. A name that is unusual in 20th century United States society, this name is imbued with fairy-tale associations. In the famous German fairy-tale “Hansel and Gretel”, Gretel and her brother are abandoned by their parents, specifically an abusive stepmother, in the forest. In Local Girls, Gretel and her brother Jason are abused by their stepmother, who yells at them repeatedly, even calling Gretel a “little bitch” (49). In the fairy tale, the stepmother leaves the children in the woods because the resources at home are too sparse. Similarly, Gretel and Jason’s stepmother, Thea, tries to push her stepchildren out of the house: Thea was talking about what a great place we were going to for dinner, and how they liked people to dress nicely, which of course was a dig at me, not that I cared about her sense of style. Then she started in on her real agenda – how the house she and my father had recently bought might look big, but it was really just right for two people. I guess she wanted...
