From the above properties it naturally follows that: • Each node (item in the tree) has a distinct key. METHOD 1 (Simple but Wrong) Following is a simple program.

...Question 1) STRENGTHS * Organisational Culture One prominent characteristic of the Geek Squad that can be identified from the video case is its clear organisational culture. From the old-school uniforms to the pin-up ties, the geek mobile to the identity inspector badges, the founder Robert Stephens fostered a corporate culture of fun. Armed with this ideology, Stephens managed to galvanise the job scope, making a typically monotonous task of repairing computer electronics more enjoyable for both his employees as well as the consumer. The glorified role of a Geek special agent allows employees to feel better about their jobs and themselves, obtaining a higher sense of accomplishment for playing a role in the overall company direction. This could also increase the loyalty of customers where they experience first-hand contact with a Geek Squad ‘Agents’, who were all ensured by the firm to be ‘well-liked’ and ‘socially interactive’. With a strong organisational culture, the Geek Squad would also be able to cultivate a sense unity among its employees who may come from various backgrounds and demographics. A shared culture would promote more communication and understanding as well as reduce conflict or any employee being left out. This would place the company in good stead in dealing with any future challenges. * Customer Service Focus The Geek Squad does not only place importance in the actual repair job, but the whole customer experience as well. According to him...

...Case Assignment week #2 The Creation of Geek Squad Technology has made communication easier and quicker while at home and while out running errands. It is constantly and persistently changing and advancing around us every day. The first key environmental factor that created an opportunity for Robert Stephens to start the Geek Squad was realizing that being attempted to stay aware of the numerous environmental changes has brought on chaos and will proceed so as long there is innovation, “particularly those related to computers, technology, software, communication, and entertainment” (Kerin, 85). Many consumers had trouble and found it hard installing, operating, and using electronic products. Some of them complains that it takes time to read the manuals. However, that being the second key environmental factor, Robert Stephens, founder of the technology support company Greek Squad, came up with the solution: “I’m going to save you that time because I stay home on Saturday nights and read them for you” (85). Stephens gave up on everything that he has gained, such as an Art Institute scholarship looking forward to get his degree in Computer Science. While student he took a part time job for a research laboratory and began repairing televisions, computers, and a variety of other items. He realized that most people needed some sort of technologic help and that “they saw value in a service whose employees would show up at a specified time, be friendly, use understandable language...

...Robert Stephens to start the Geek Squad? The many changes in the environment that occurred were related to technology, computers, software, communications, entertainment, and social factors such as demographics and cultures, all things he came to realize during his consulting years. While Stephens was attending college and working towards earning a degree in computer science, he also worked as a consultant repairing televisions, computers, and several other items; however his main focus was computers. Through his consulting experience, he came to realize that most people needed help with technology, such as, how it works, its operating system, how to install software, and especially how to read and understand the manuals. 2) What changes in the purchasing patterns of (a) all consumers and (b) woman made the acquisition of Geek Squad particularly important for Best Buy? Changes in social factors such as demographics and culture helped make Geek Squad very popular. In the past, many manufacturers and retailers focused primarily on men. However, they found that woman were becoming increasingly more and more interested in the personal computing and home entertainment. Best Buy’s consumer research began indicating that woman will more than likely outspend men in the near future. Furthermore, Best Buy’s consumer research has proven that women tend to expect personal service during the purchasing and installation after the purchase, just what the Geek Squad is designed to provide...

...In 1994, Robert Stephens, was a computer science college dropout that founded Geek Squad with $200 and a bicycle in Minneapolis, Minnesota. Dressed in white button-down shirts, too-short black pants, white socks and clip on ties, Geek Squad technicians (known as Agents) repaired computers in local businesses and in customer homes. Stephens had the idea that pulling up on a bicycle dressed like a “geek” would inspire a weird confidence in his computer repair skills. It did. Eight years later, Geek Squad was acquired by Best Buy for an undisclosed amount. Today, Geek Squad is comprised of over 20,000 highly skilled and specially trained computing Agents, home entertainment installers (GSI), Autotechs and appliance repair technicians (GSR’s) located in all U.S. Best Buy stores, at Geek Squad stand-alone locations as well as at service centers located nationwide. Geek Squad provides residential and commercial product repair, support, and installation services both in store and on site. Best Buy acquired Geek Squad to help develop a technological support system for its customers. At the time of acquisition, Best Buy sold computers but didn’t have an effective way to service them. It’s one thing to know the difference between two computers, but another to be able to effectively diagnose a wide range of problems and have the required parts to do so. This related acquisition allowed Best Buy and Geek Squad customers to get a premium level of customer service for their technology...

Some leaders can influence and motivate those around them more effectively and easily than others and guide them to be a more coherent and cohesive unit in order to accomplish the objectives and targets. All three main characters in this case, exhibit different management styles and approaches which clearly differentiates them as not only managers but also as individuals with a different approach, conditioning and thought process (Zastrow, 2008). Rick clearly displays all the traits of delegative leadership or a Laissez Fare approach to leadership. It is a leadership style...

...What are stereotypes? Basically, it’s the way people judge other people by their looks and the way they act. This happens a lot in Freaks and Geeks and in the world today. Some stereotypes that are commonly projected upon teenage characters are geeks, freaks, and jocks. Each character falls into one of these categories. I feel that these portrayals are fair because these stereotypes are used in the show and they exist in today’s world. One stereotype category used in this show is geeks. What exactly are geeks though? Geeks are people who are small, smart, unathletic, anti-social, they like sci-fi things, science, games, and toys. A few people in the show are in this category. Sam, Neil, and Bill fall into this stereotype. For example, Neil...

...So many dead, so many blacked bodies lay among the burning rubble that it caused trained firefighters to vomit and quit their jobs on the spot. Such was the scene of the once great Binewski Family Carnival Fabulon, at the climax of Geek Love, a novel by Katherine Dunn. Al and Lil Binewski taught their children, which they used for their traveling freak show that the thoughts and opinions of women mattered very little. The Binewski family went out in a blaze of glory, but their tragic end could have been avoided had the men and women within the family been treated equally. The oppression of women throughout Geek Love, by Katherine Dunn leads to the destruction of the Binewski family, their beloved Fabulon, and countless other lives. As the...

...We’ve all heard the name Geek Squad before. Most of us know what they do, maybe some have even taken advantage of the services they offer, but how did it get to be the household name it is today? Founder of the company, Robert Stephens, was, like all entrepreneurs, faced with an abundance of challenges before and after starting his business. Stephens was also given a great opportunity with the beginning of a trend toward personal computers when he started his business. In fact, Geek Squad had become so successful that it was brought to the attention of Best Buy, which purchased the company from Stephens in 2002 to combat some issues they thought that Geek Squad would be able to fix for them. Although they have been extremely successful up to this point, Geek Squad will need to stay ahead of the game to continue to do so, with the rapidly growing and ever changing technological world. When Robert Stephens was studying computer science, he also worked fixing computers for a research laboratory, and started consulting as well. While consulting he realized that most people needed help using and/or fixing their personal computer. In 1994 when Stephens started the company, it was in high demand because of the increase in the use of the personal computer (PC). The people not only wanted someone to help with their computer problems, but also be on time and help them understand what the problem really is, all while being friendly. When Best Buy purchased Geek Squad in 2002 for $3 million...

...Media techniques in any television show can help create an interesting plot line or intriguing characters to reel in the audience. The director of the classic sitcom Freaks and Geeks uses the media techniques pan camera angle and music to depict the different cliques that exist in the school. Music is used effectively to show the different cliques that exist in the show; this is possible because the genre of music that is played reflects the personalities of the cliques being shown. At the very beginning of the episode the directors shows two different types of cliques and has a different genre of music accompanying their scene (Kasdan 1999). There are two distinct cliques portrayed in this scene and each had their own genre of song playing...

...Aryan Shankar Catherine Thomas English I 2 November, 2015 Iron Man and its Role in Creating a ‘Positive Geek Culture’ Superheroes are everywhere these days. Although, the origin of superheroes can be traced back to the comic books of the 1930s and even earlier, they have been depicted in media like film, television shows, video games, radio broadcasts and graphic novels. They even find their place in apparels like t-shirts, sweatshirts, socks and underwear; stationery items like pencil boxes; accessories for electronic gadgets like cell phone covers and laptop skins; and various home furnishing items. Originally confined to a certain class of comic book fans, the popularity of superheroes has reached a wider audience with a lot of different people being happily associated with them. This phase of increasing infusion of superheroes into the mainstream culture started in the 1990s and the early part of the 21st century but it was only after the release of the film Iron Man that superheroes reached their present level of popularity. Therefore, it can be argued that Iron Man has led to the creation of what can be called, a ‘positive geek culture’. ‘Geek culture’, as it is popularly understood, has many different facets and it is not always associated with being a superhero fan. Geek culture includes interest in board games like Dungeons & Dragons, the film series Star Wars and martial arts films of the 1980s, and television series like Star Trek, Battlestar...
