Gen. Henry Hap Arnold - World War II History
Gen. Henry Hap Arnold - World War II History Henry Harley Arnold (born at Gladwyne, PA on June 25, 1886) had a military career peppered with many successes and few failures. He was the only officer to ever hold the rank of General of the Air Force. He died January 15,Ã 1950Ã and was buried at Arlington National Cemetery. Early Life The son of a doctor, Henry Harley Arnold was born at Gladwyne, PA on June 25, 1886. Attending Lower Merion High School, he graduated in 1903 and applied to West Point. Entering the academy, he proved a renowned prankster but only a pedestrian student. Graduating in 1907, he ranked 66th out of a class of 111. Though he desired to enter the cavalry, his grades and disciplinary record prevented this and he was assigned to the 29th Infantry as a second lieutenant. Arnold initially protested this assignment but ultimately relented and joined his unit in the Philippines. Learning to Fly While there, he befriended Captain Arthur Cowan of the US Army Signal Corps. Working with Cowan, Arnold aided in creating maps of Luzon. Two years later, Cowan was ordered to take command of the Signal Corps newly-formed Aeronautical Division. As part of this new assignment, Cowan was directed to recruit two lieutenants for pilot training. Contacting Arnold, Cowan learned of the young lieutenants interest in obtaining a transfer. After some delays, Arnold was transferred to the Signal Corps in 1911 and began flight training at the Wright Brothers flying school in Dayton, OH. Taking his first solo flight on May 13, 1911, Arnold earned his pilot license later that summer. Sent to College Park, MD with his training partner, Lieutenant Thomas Millings, he set several altitude records as well as became the first pilot to carry US Mail. Over the next year, Arnold began to develop a fear of flying after witnessing and being a part of several crashes. Despite this, he won the prestigious Mackay Trophy in 1912 for the most meritorious flight of the year. On November 5, Arnold survived a near-fatal crash at Fort Riley, KS and removed himself from flight status. Returning to the Air Returning to the infantry, he was again posted to the Philippines. While there he met 1st Lieutenant George C. Marshall and the two became life-long friends. In January 1916, Major Billy Mitchell offered Arnold a promotion to captain if he returned to aviation. Accepting, he traveled back to College Park for duty as the supply officer for the Aviation Section, US Signal Corps. That fall, aided by his friends in the flying community, Arnold overcame his fear of flying. Sent to Panama in early 1917 to find a location for an airfield, he was en route back to Washington when he learned of the US entry into World War I. World War I Though he desired to go to France, Arnolds aviation experience led to him being retained in Washington at the Aviation Sections headquarters. Promoted to the temporary ranks of major and colonel, Arnold oversaw the Information Division and lobbied for the passage of a large aviation appropriations bill. Though mostly unsuccessful, he gained valuable insight into negotiating the politics of Washington as well as the development and procurement of aircraft. In the summer of 1918, Arnold was dispatched to France to brief General John J. Pershing on new aviation developments. Interwar Years Following the war, Mitchell was transferred to the new US Army Air Service and was posted to Rockwell Field, CA. While there, he developed relationships with future subordinates such as Carl Spaatz and Ira Eaker. After attending the Army Industrial College, he returned to Washington to the Office of the Chief of Air Service, Information Division, where he became a devout follower of the now-Brigadier General Billy Mitchell. When the outspoken Mitchell was court-martialed in 1925, Arnold risked his career by testifying on behalf of the air power advocate. For this and for leaking pro-airpower information to the press, he was professionally exiled to Fort Riley in 1926 and given command of the 16th Observation Squadron. While there, he befriended Major General James Fechet, the new head of the US Army Air Corps. Intervening on Arnolds behalf, Fechet had him sent to the Command and General Staff School. Graduating in 1929, his career began to progress again and he held a variety of peacetime commands. After winning a second Mackay Trophy in 1934 for a flight to Alaska, Arnold was given command of the Air Corps First Wing in March 1935 and promoted to brigadier general. That December, against his wishes, Arnold returned to Washington and was made Assistant Chief of the Air Corps with responsibility for procurement and supply. In September 1938, his superior, Major General Oscar Westover, was killed in a crash. Shortly thereafter, Arnold was promoted to major general and made Chief of the Air Corps. In this role, he began plans for expanding the Air Corps to place it on par with Army Ground Forces. He also began pushing a large, long-term research and development agenda with the goal improving the Air Corps equipment. World War II With the growing threat from Nazi Germany and Japan, Arnold directed research efforts to exploit existing technologies and drove the development of aircraft such as the Boeing B-17 and Consolidated B-24. In addition, he began pushing for research into the development of jet engines. With the creation of the US Army Air Forces in June 1941, Arnold was made Chief of the Army Air Forces and acting Deputy Chief of Staff for Air. Given a degree of autonomy, Arnold and his staff began planning in anticipation of the US entry into World War II. Following the attack on Pearl Harbor, Arnold was promoted to lieutenant general and began enacting his war plans which called for the defense of the Western Hemisphere as well as aerial offensives against Germany and Japan. Under his aegis, the USAAF created numerous air forces for deployment in the various theaters of combat. As the strategic bombing campaign commenced in Europe, Arnold continued to press for the development of new aircraft, such as the B-29 Superfortress, and support equipment. Beginning in early 1942, Arnold was named Commanding General, USAAF and made a member of the Joint Chiefs of Staff and the Combined Chiefs of Staff. In addition to advocating for and supporting strategic bombing, Arnold backed other initiatives such as the Doolittle Raid, the formation of the Women Airforce Service Pilots (WASPs), as well as communicated directly with his top commanders to ascertain their needs firsthand. Promoted to general in March 1943, he soon had the first of several wartime heart attacks. Recovering, he accompanied President Franklin Roosevelt to the Tehran Conference later that year. With his aircraft pounding the Germans in Europe, he began focusing his attention on making the B-29 operational. Deciding against using it Europe, he elected to deploy it to the Pacific. Organized into the Twentieth Air Force, the B-29 force remained under Arnolds personal command and flew first from bases in China and then the Marianas. Working with Major General Curtis LeMay, Arnold oversaw the campaign against the Japanese home islands. These attacks saw LeMay, with Arnolds approval, conduct massive firebombing attacks on Japanese cities. The war finally came to an end when Arnolds B-29s dropped the atomic bombs on Hiroshima and Nagasaki. Later Life Following the war, Arnold established Project RAND (Research and Development) which was tasked with studying military matters. Traveling to South America in January 1946, he was forced to break off the trip due to declining health. As result, he retired from active service the following month and settled on a ranch in Sonoma, CA. Arnold spent his final years writing his memoirs and in 1949 had his final rank changed to General of the Air Force. The only officer to ever hold this rank, he died on January 15, 1950 and was buried at Arlington National Cemetery. Selected Sources HistoryNet: General Henry Hap ArnoldHenry H. Arnold

How stuff work Research Paper Example | Topics and Well Written Essays - 750 words
How stuff work - Research Paper Example This invention came into the limelight immediately because it was the key in solving one of the biggest environmental challenges-Oil spills and was concept of bioremediation since no harmful chemicals or other products were employed. Oil spills always have a catastrophic effect on the marine ecosystem as well as those who depend on the marine ecosystem .such as birds, fishing industry and tourism industry. The toxic oil stuck to the birdââ¬â¢s feathers prohibiting them from flying and has serious effects on the marine life as well. Until the invention of these microbes the cost of cleaning up the oil was extremely high. Using techniques such as dispersants or mechanical skimming cost almost $7,350 per metric ton of oil. Often oil was spilled in the middle of the ocean where logistics posed a great problem and in most cases only a mere 20% of the oil spilled could be cleaned up. However the invention of these oil-eating microbes have been a boon to mankind since these microbes make the cleaning up process practical, rapid and environment friendly. Production of Oil eating Bacteria Oil especially crude oil is composed of hydrocarbons. Many bacteria and fungi have the natural capability of breaking down oil into carbon dioxide and water however none of the naturally occurring bacteria could degrade all the components. While working with microbes he recognized the fact that microbial metabolism could be used for the process of bioremediation. Recombinant DNA technology also known as RDT is the technology used by biotechnologists and genetic engineers to transfer DNA or genetic material from one cell to another with the help of vectors or carrying bodies such as plasmids. Certain bacterial strains already bore the gene which encodes for specialized enzymes. These specialized enzymes have the capability of degrading oil, nullifying their toxicity and turning them into harmless products. Using recombinant DNA technology, Professor isolated the genes from these micr obes and integrated them into the vector plasmid DNA machinery. These plasmids were then integrated into strains of Pseudomonas bacteria. These genetically engineered bacteria were now made capable of producing enzymes on their own which could degrade oil and render them harmless. Working principle The entire working principle of the oil degrading microbes is based on the study of enzymes. The enzymes help the bacteria in obtaining their carbon from the oils. Once these microbes are put into the water containing oil, their only source of carbon is the oil on the water surface. The bacteria which can produce oil-degrading enzymes start production and utilizes the degraded oil as its energy resource. Hydrocarbon degrading enzymes such as alkane hydroxylase, catechol dioxygense are some of the enzymes that are encoded by the genes of some naturally occurring oil0degrading bacteria and which have been genetically transferred into Pseudomonas strain enabling the latter to break down a wi de variety of oil components (Peixoto et al,2011, p.2). The bacteria proliferates at the site of oil spill since large quantities of carbon resource is available. Problems

Discuss the overall trend in postwar aggregate productivity in the US Essay
Discuss the overall trend in postwar aggregate productivity in the US - Essay Example labor has been averaging around slightly above one percent faster than MFP: from 1953-2012, labor productivity grew at an annual rate of 2.2 percent per year, and MFP grew at an annual average rate of 1.1 percent per year ().this projects a volatile economic growth rate annually. The volatility could be attributed to measurement error in estimation arising from both series. Getting an accurate measurement of these rates is a daunting task given the fluctuations in the rates market. Another reason stems from the fact that series have certain gas between then that cyclical. To illustrate this, consider when the MFP growth fellââ¬âin fact, took on negative valuesââ¬âduring the recessions that started in 1969, 1980-81, 1990, and 2007 ().the negative values are an indication of how less optimal the inputs have become in yielding the expected returns. Besides, a negative MFP growth can also arise from variation in the utilization rates of capital and labor over the business cycle (). In the last 60 years the long-term mean growth rates of labor productivity and MFP have varied substantially in three episodes. In the initial episode, the 1950s through early 1970s, there was a high growth of MFP.MFP growth averaged at 1.7 percent per year from 1953 through 1972. In the next episode, from the late 1970s through early 1990s, there were lower MFP growth with an average of 0.5% annually. In the last episode, from the mid-1990s up to now, experiencing an intermediate level of MFP growth of 1.0%

A look at why Gorbachev's reforms failed in the former Soviet Union Term Paper
A look at why Gorbachev's reforms failed in the former Soviet Union while Deng Xiaoping's reforms succeeded in China - Term Paper Example His policy of Glasnost or openness was also an integral part of his restructuring as well. The essence of these reforming exercises was largely the movement towards economic liberalization and plausible democratic transparency ââ¬â to the extent as it augured well with the need for necessary change (Kessler, 1988, 651). Indeed, what Deng could foresee in 1978, Gorbachev and erstwhile Soviet political stalwarts took yet another eight years to conceive! Chinaââ¬â¢s journey to realizing need for globalization began with Dengââ¬â¢s very first visit to United States for meeting President Carter. When USSR started with restructuring economy and polity, China was already way ahead in this process. Does it mean that Deng was better entrenched in the corridors of power in China than Gorbachev in Soviet Union? There can be quite few reasons behind this apparent ââ¬Ëback bencherââ¬â¢ attitude of the Soviet Union. Despite other international political designs, China was not so globally involved with the cold war mutual vilifications and indirect fighting with the United States (US). The Soviet Union had to waste a lot of her resources and energy in the cold war with US. In view of Soviet involvement in Afghanistan and tremendous pressure upon it during cold war and dà ©tente, USSRââ¬â¢s weal ec onomy could not really bear the burden of a so-called socialist polity and economy ââ¬â largely closed to the outside world. However, in order to critically analyze and compare both Perestroika and Dengââ¬â¢s reforms it is required to know the major aspects of both these perspectives. First, main aspects of Perestroika may be pointed out: The Gorbachev leadership, however, regarded its reforms in the USSR as a development of socialism, a ââ¬Å"modernization,â⬠as it were, of socialism to bring it up to date in the modern epoch. The policy of perestroika has â⬠¦. The proposals of the reform movement

Todays Consumer Culture: Bought Self-worth and Artificial Happiness Es
"There's a lady who's sure all that glitters is gold And she's buying a stairway to heaven. When she gets there she knows, if the stores are all closed With a word she can get what she came for. Ooh, ooh, and she's buying a stairway to heaven." From "Stairway To Heaven", by Led Zeppelin Shopping malls didn't just happen. They are not the result of wise planners deciding that suburban people, having no social life and stimulation, needed a place to go (Bombeck, 1985). The mall was originally conceived of as a community center where people would converge for shopping, cultural activity, and social interaction (Gruen & Smith, 2005). It is safe to say that the mall has achieved and surpassed those early expectations. Unfortunately, in today's consumer culture, the mall is the center of the universe and and this has shaped consumers in a negative way. In contrast to the original concept of providing the consumer with greater choice, the mall actually limits the choices of the suburb shopper. The consumer is forced to go to the mall to full-fill shopping needs, but, once inside, also made to feel guilty if they do not make any purchases. The mall promotes materialism and superficiality, a sense of bought self-worth and artificial happiness. Housing shortages and increased mobility (car) allowed families to move away from the city and into the suburbs. These areas were designed to be self-contained, pre-packaged communities with schools, parks, homes, etc within close proximity of each other. Not far from jobs in the city, the suburbs provided the safe, enclosed realm ideal for raising families. The only problem was the fact that most stores were downtown and too far for mothers (who did most of the shopping) to driv... ...y, advocates this cycle of earning money, spending money, and buying happiness. Overall, the malls promote a sense of superficiality, a need to acquire goods for social acceptance, and an emphasis on artificial happiness. Though they began with innocent intentions, the sinister effects of changing societal values has left us in a jeopardizing situation. Our shallow "needs" for consumer goods have weakened society and compromised our position as a close community. Ã Works Cited Gruen, V., and Smith, L.

Ethics: Hedonism and Pleasure Essay
1) The difference between physical and attitudinal pleasure is that one is something that you can hold and grab, while the other is something that is in your mind. To expand, physical pleasure is a temporary thing. For an example: Eating key lime pie. Eating this specific pie for some people give them pleasure because it tastes good; however, when the consumption is complete, the taste eventually goes away along with the pleasure. On the other hand, attitudinal, or psychological pleasure, is a perpetual kind of happiness instead of the momentary pleasure that physical pleasure gives you. Hedonists take the side that attitudinal pleasure is intrinsically valuable; however this distinction is solely based on the fact that attitudinal please has a more lasting effect then that of its counterpart. Yet, hedonists attract and claim this position because each person is different, and the freedom to follow what makes for a good life is individualistic. 2) The Hedonism theory claims that all pleasures are intrinsically good, and that nothing other than pleasure is intrinsically good. However my objection to this statement is that the overall life satisfaction is not acquired through experiencing constant pleasures, and that experiences life only through chasing pleasurable actions will only end unpleasant. Also, hedonism states that good is pleasure and bad is pain. In distinction, if having an appetite is painful (bad) and satisfying an appetite is pleasant (good), a person will experience both pleasure and pain when satisfying an appetite. Therefore feeling pleasure and feeling pain are not the same as doing well and doing badly. Page40-41 2) If I had the chance to get into the ââ¬Å"experience machineâ⬠I would not, because the experience machine is known to counter ethical hedonism. Doing so would only be contradictory towards my belief of hedonism. One of the arguments against plugging into the experience machine is that the experience machine limits people to a man-made reality. Gaining enjoyment without actions defeats the purpose of experiences; therefore, residual happiness is destroyed because you had no drive or will to gain that happiness. 5) I believe the strongest objection towards hedonism is that feeling pleasure and feeling pain are not the same as doing well and doing bad. A hedonist would state that all pleasure is good and pain is bad; however, one can experience pain and pleasure at the same time, which makes neither of them good or bad.
