The mid-1920’s ushered in a variety of new inventions. Gas chambers, invented in 1924 in the state of Nevada, developed a more peaceful execution. In 1924, James Spangler invented the Hoover Machine, an invention known around the world. Spangler invented the vacuum, and his cousin’s husband, William Hoover, bought his machine first. William Hoover later owned the Hoover Vacuum Company. ("Invention and History of Vacuum Cleaners", 2015)(McGrath, 1999, pp. 832-833). Changing the world and the future, Robert H. Goddard, successfully built a liquid-fueled rocket and launched it on March 16, 1926.

The clip on tie and bow tie, invented in 1928, helped officials greatly. Police officers preferred wearing clip on ties with their dangerous jobs. This way, criminals could not gain leverage on grabbing the officers tie and strangling them with the that went around their neck. Although the clip on tie was frowned upon in some social settings, it made policemen much more confident in their duties. (Sandhyarani, 2013)("Featured On Our Blog", 2015). Saving many lives jeopardized by the disease of Polio, the Negative Pressure Ventilator, also known as the Iron Lung, added incredible advances in the medical field. The Iron Lung, invented by Louis Shaw and Philip Drinker, forces a patient's lungs to inhale and exhale through changes in pressure. The machine encloses the entire body except the head and kept completely air tight. Drinker and Shaw, both medical students at Harvard, used vacuum cleaners to experiment with the changes in pressure that are involved with the Negative Pressure Ventilator. (Sandhyarani, 2013)("History of the Iron Lung or Respirator", 2015). Penicillin, the first effective antibiotic ever, added another advancement to the medical industry in 1928. Sir Alexander Fleming found penicillin mold on his workbench when he came home from a trip to Scotland. He discovered that the mold prevented the growth of a bacteria. After his discovery, he worked non-stop to find a way to use this bacteria killing mold to mankind's benefit. Fleming said, “When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I guess that was exactly what I did.”("The Real Story Behind Penicillin", 2015)(Sandhyarani, 2013). Sam Foster, founder of the Foster Grant Company, introduced sunglasses as eye protectants in 1929. Foster stood on beaches and sold the glasses to people, telling them that they would protect their eyes

Dyson Case

...M17_HOLL6227_05_SE_C17.qxd 5/20/10 4:06 PM Page 641 CASE STUDY IV.3 Dyson Vacuum Cleaner: shifting from domestic to international marketing with the famous bagless vacuum cleaner The Dyson history It is impossible to separate the very British Dyson vacuum cleaner from its very British inventor. Together they are synonymous with innovation and legal battles against established rivals. James Dyson was born in Norfolk in 1947. He studied furniture design and interior design at the Royal College of Art from 1966 to 1970 and his first product, the Sea Truck, was launched while he was still Courtesy of Dyson. studying. Dyson’s foray into developing vacuum cleaner technology happened by chance. In 1978, while renovating his 300-year-old country house, Dyson became frustrated with the poor performance of his conventional vacuum cleaner. Whenever he went to use it, there was poor suction. One day he thought he would find out what was wrong with the design. He noted that the appliance worked by drawing air through the bag to create suction, but when even a fine layer of dust got inside, it clogged its pores, stopping the airflow and suction. In his usual style of seeking solutions from unexpected sources, Dyson noticed how a nearby sawmill used a cyclone – a 30-foot-high cone that spun dust out of the air by centrifugal force – to expel waste. He reasoned that a vacuum cleaner that could separate dust by cyclonic action and spin it out of the ...

There is however, quite none like the Gaming Industry. The beginning of gambling can be traced to religious rituals in pre-historic societies. The rituals had a purpose of predicting the future. The procedure of the rituals was simple and consisted of “casting the lots” throwing small objects like pebbles, sticks, nuts, arrows etc. out of the palms of the hands or any container (Hoovers, 2012). The result was checked to see if the number of the objects on the ground was “odd” or “even”. “Even” number meant a positive outcome and “odd” stood for a negative one. With time that process became more complex and also involved interpreting the patterns of the objects lying on the ground. The next step in the evolution of these rituals integrated the sacrifices from the participants to encourage the fate of the Gods to deliver positive signs and help. The sacrifices were normally personal stakes which turned those involved from observers into active players of the process. They gambled their stakes on the outcome that depended on chance only. Eventually the same type of chance-based dealings grew into their every-day life. Gambling...

This Is It

...Competitive strategy at Whole Foods Market By Amanda Roberson, Amy Zelezen, Ankush Brahmavar, Boris Pilipenko, Kinjal Gandhi and Matt Werner Cincinnati resident Roberta Mand is spoiled for choice every time she steps out to buy groceries. Depending on whether she want to buy steaks, sushi, staples or macadamia-encrusted tuna, she heads to Costco, Wal-Mart, Kroger, Whole Foods or the local farmer’s market, all of which are nearby. Roberta’s array of choices illustrates the ever-evolving dynamics of the grocery industry. In this extremely competitive environment, all major players must continuously strategize to maintain a strong presence. A look at Whole Foods Market reveals how this increased competition can leave a company at a strategic crossroads. Since its beginnings in 1980, Whole Foods has been a leader in supplying organic and natural foods, and for years enjoyed its role as the only store catering to this niche market. However, since then other major players have identified this growing segment and now also carry lines of organic and natural foods. Shoppers like Mand can now buy most specialty items almost anywhere. Competitors, such as Safeway and Kroger, bring with them vast experience in supply chain and vendor development, which allows them to optimize more effectively, use economies of scale, and reduce costs. Despite a public perception that Whole Foods competes against the Sunflower Markets and Trader Joe’s of the world, neither the company itself nor analysts...

...and it had left many people severely disabled. It was while working with amputees that her inventive ideas were develop to assist her patients in regaining their independence. By 1951 Blount was living in Newark, New Jersey and teaching Physical Therapy at the Bronx Hospital in New York. She taught people to do the work that their feet and hands once did. Eating was a great challenge for many of the people that she was working with. To assist disabled people in gaining greater independence she invented a device that delivered food through a tube, one bite at a time, to a mouthpiece that could be used whether the patient was sitting up or lying down. When the person wanted more food they would just bit down on the tube and it signaled a machine to send the next bit. This electric self-feeding devise eventually was donated to France. In 1951, she patented a simple device called a “portable receptacle support” which also allowed people to feed themselves. It used a brace around the neck to support a bowl, cup or dish. In the 1953 Blount appeared on the Philadelphia television show “The Big Idea” being the first Black and the first woman to be appear on such show. While her inventions had the potential to revolutionize the lives of many people, getting them patented and marketed for use by patients was not easy in the United States.

The Importance Of Standardized Testing

...Objectiveness 3.1. Standardized test is more objective than any other kind of test. The word “standardized” predestines standardized test’s nature: objective. Different than the points and tests graded by local teachers, standardized test needs electronic machines and standardized test paper and questions to assure that one student’s ability is clearly and precisely reflected into numbers. Also, without knowing identity of students, the paper-grader can make appropriate decisions without stereotypes and prejudices. 3.2. Standardized test is an unfair assessment and a malicious tool. According to Carol Dweck, psychological professor in Harvard University, one person did well on tests, he or she will be acclaimed as a smart student, and the consequence will enter as fixed mindset. If praised as worked hard, it will enter as malleable mindset. Fixed mindset doesn’t help much, because when students go to next puzzle, which can difficult, it will threaten their schema: if they don’t achieve, the omen of the aftermath will be being no longer smart.

Ethanol

...DMACC THE ETHANOL ENVIORMENT A RESEARCH PAPER SUBBMITTED TO MR. JEFF WILLIAMS INTRODUCTION TO ETHICS PHI 105 BE BOONE, IA NOVEMBER 17, 2014 Abstract Ethanol is a renewable resource that is produced from many agricultural products. The public attitude towards corn based ethanol is influenced by many different subjects like, the effects of production on the environment, the effects on local economies, and the effects on the national food prices. Focusing on corn based ethanol there are considerations to take into effect such as the benefits of ethanol, the problems or concerns with ethanol, the political involvement with ethanol, and the effect of ethanol on the economy. The Ethanol Environment Ethanol is a renewable resource that is produced from many agricultural products such as corn, which can be blended into many different proportions of gasoline. The public attitude towards corn based ethanol is influenced by many different subjects. The overall plan for ethanol was good but took a wrong turn and has caused damage as a result. As stated by Michelle Heath, “there are no known environmental hazards that have to do with ethanol.” Ethanol does not only make our vehicles friendlier to the environmental it also has other impacts. Considering our total energy use, including building, heating and electricity, the savings from the use of biofuels is two-thirds greater than using gasoline (Dewsbury, 2009). With the increased...

I n late 1979, a twenty-four-year-old entrepreneur paid a visit to a research center in Silicon Valley called Xerox PARC. He was the co-founder of a small computer startup down the road, in Cupertino. His name was Steve Jobs. Xerox PARC was the innovation arm of the Xerox Corporation. It was, and remains, on Coyote Hill Road, in Palo Alto, nestled in the foothills on the edge of town, in a long, low concrete building, with enormous terraces looking out over the jewels of Silicon Valley.

...Abiola Idowu Ashford University BUS640 Operations Management September 26, 2011 Introduction: Porter’s model is based on the insight that a corporate strategy should meet the opportunities and threats in the organizations external environment, especially competitive strategy should be based on the understanding of an industry’s structure and the way they change. Porter has identified five competitive forces that shape every industry and every market. These forces determine the intensity of competition and hence the profitability and attractiveness of an industry. The objective of corporate strategy should be to modify these competitive forces in a way that improves the position of the organization. Porter’s model supports the analysis of the driving forces in an industry. Based on the information derived from the five forces analysis, management can decide how to influence or to exploit particular characteristics of their industry. The five competitive forces are typically described as follows: bargaining power of suppliers, the term 'suppliers' comprises of all sources for inputs that are needed in order to provide goods or services, supplier bargaining power is likely to be high when the market is dominated by a few large suppliers rather than a fragmented source of supply, there are no substitutes for the particular input, the suppliers, customers are fragmented so their bargaining power is low, the switching costs from one supplier to another are high there is the...

Although those economies were still substantially poorer and smaller than those of the West, the speed with which they had transformed themselves from peasant societies into industrial powerhouses, their continuing ability to achieve growth rates several times higher than the advanced nations, and their increasing ability to challenge or even surpass American and European technology in certain areas seemed to call into question the dominance not only of Western power but of Western ideology. The leaders of those nations did not share our faith in free markets or unlimited civil liberties. They asserted with increasing self-confidence that their system was superior: societies that accepted strong, even authoritarian governments and were willing to limit individual liberties in the interest of the common good, take charge of their economies, and sacrifice short-run consumer interests for the sake of long-run growth would eventually outperform the increasingly chaotic societies of the West. And a growing minority of Western intellectuals agreed. The gap between Western and Eastern economic performance eventually became a political issue. The Democrats recaptured...
