George Wells Beadle was born at Wahoo, Nebraska, U.S.A., October 22, 1903, the son of Chauncey Elmer Beadle, a farmer, and his wife Hattie Albro. George was educated at the Wahoo High School and might himself have become a farmer if one of his teachers at school had not directed his mind towards science and persuaded him to go to the College of Agriculture at Lincoln, Nebraska. In 1926 he took his B.Sc. degree at the University of Nebraska and subsequently worked for a year with Professor F.D. Keim, who was studying hybrid wheat. In 1927 he took his M.Sc. degree, and Professor Keim secured for him a post as Teaching Assistant at Cornell University, where he worked, until 1931, with Professors R.A. Emerson and L.W. Sharp on Mendelian asynopsis in Zea mays. For this work he obtained, in 1931, his Ph.D. degree. In 1931 he was awarded a National Research Council Fellowship at the California Institute of Technology at Pasadena, where he remained from 1931 until 1936. During this period he continued his work on Indian corn and began, in collaboration with Professors Th. Dobzhansky, S. Emerson, and A.H. Sturtevant, work on crossing-over in the fruit fly, Drosophila melanogaster.
In 1935 Beadle visited Paris for six months to work with Professor Boris Ephrussi at the Institut de Biologie physico-chimique. Together they began the study of the development of eye pigment in Drosophila which later led to the work on the biochemistry of the genetics of the fungus Neurospora for which Beadle and Edward Lawrie Tatum were together awarded the 1958 Nobel Prize for Physiology or Medicine.
In 1936 Beadle left the California Institute of Technology to become Assistant Professor of Genetics at Harvard University. A year later he was appointed Professor of Biology (Genetics) at Stanford University and there he remained for nine years, working for most of this period in collaboration with Tatum. In 1946 he returned to the California Institute of Technology as Professor of Biology and Chairman of the Division of Biology. Here he remained until January 1961 when he was elected Chancellor of the University of Chicago and, in the autumn of the same year, President of this University.
During his career, Beadle has received many honours. These include the Hon. D.Sc. of the following Universities: Yale (1947), Nebraska (1949), Northwestern University (1952), Rutgers University (1954), Kenyon College (1955), Wesleyan University (1956), Birmingham University and Oxford University, England (1959), Pomona College (1961), and Lake Forest College (1962).
Charles attended Brentwood School in Essex which is father was headmaster of but in 1894 Charles changed schools to Clifton College before winning a scholarship to Hertford College in Oxford in 1898.
When he graduated from Dartmouth College in 1925 after that he attended Lincoln College at Oxford.
After two years at Fisk University, DuBois transferred to Harvard his junior year. In 1890, he graduated cum laude from Harvard and was one of the six graduation speakers. He continued his education by pursuing graduate studies at the University of Berlin in history and economics. DuBois received his master of arts in 1891 and in 1895 received his doctorate in history from Harvard.... ...
Gregor Mendel was born into a German family, as a young man Mendel worked as a gardener and studied beekeeping. In his later life Mendel gained his fame as the founder of the modern science of genetics. The research that was his claim to fame was his pea plant experiment. Mendel looked at seven different characteristics of the pea plants. For example with seed colors when he bred a yellow pea and green pea together their offspring plant was always yellow. Though, in the next generation of plants, the green peas reemerged at a 1:3 ratio. To explain what he had discovered, Mendel put together the terms “recessive” and “dominant” in reference to specific traits. Such as, in the previous example the green peas were recessive and the yellow peas
More than 37 years ago, Rollin King and Herb Kelleher got together and decided to start a different kind of airline. They began with one simple notion: If you get your passengers to their destinations when they want to get there, on time, at the lowest possible fares, and make darn sure they have a good time doing it, people will fly your airline. And you know what? They were right. What began as a small Texas airline has grown to become one of the largest airlines in America. Today, Southwest Airlines flies over 104 million passengers a year to 64 great cities all across the country, and we do it more than 3,400 times a day.
Pricing. Their pricing strategy is based off their market position as a budget airline. Positioning their company as a budget airline, Southwest can maintain and keep their lower price points compared to their competitors. For Southwest to maintain sustainability as a market leader, they must effectively utilize their resources to reduce their cost of operations. By only operating one type of aircraft, short non-stop flights, point to point routes, and flying into less crowded secondary airports, this has allowed Southwest Airlines to keep their price points down while simultaneously reducing their planes turnaround time.
Since CEO Gary Kelly took the reins of the company back in 2004, Southwest has maintained and enhanced the company’s ability to offer customers a great flying experience for low fares. This effort start early in Mr. Kelly’s tenure when he identified four success factors
Southwest Airlines business opened for operations in 1971, after Rollin King and Herb Kelleher raised enough capital to finance their plan. Their service model broke off from the typical large airline policies and procedures. The typical model had an airline that was “home based” from a hub and ran routes to and from that location. This model added cost that Southwest wanted to avoid, causing them to implement point-to-point flights. The leadership team also made decisions to eliminate the inflight meal options to reduce overhead costs. Customer service and the overall experience of their customers became the valued operating vision and mission for Southwest. Eventually utilizing technology for online booking to the fullest potential saved precious time and gained efficiencies. Though the company started strong and grew slowly, several elements affected the long-term success of the company. Some of the factors that caused Southwest to reevaluate organic growth processes included not operating out of key United States hubs, the rise in fuel costs, and troubled contract negotiations.
Southwest Airlines is operating in an industry that is struggling to make profits. The slowing economic growth and raising fuel costs are lowering earnings while revenues remain the same. The macroeconomic factors affecting the airline industry include unemployment, the economic growth in the United States, and inflation. With low economic growth, consumers are finding luxury items more difficult to purchase and airline tickets for vacations fall into that category. Unemployment contributes to a lack of vacation travelers since individuals who are not employed do not have extra money for vacation or airline tickets. Inflation also causes operating costs of the airlines to be higher cutting into profits.
Southwest Airline’s greatest strength is their financial stability. They are able to maintain profits even when the industry is in economic crisis. Their financial success is in large part due to their low operational costs. Short haul, point-to-point trips allow them to save time and money. This not only provides faster trips to customers with shorter wait time, but also increase the amount of customer turnover which provides more profitability. Southwest should continue to operate at low costs so they may continue to provide low prices to their customers, since cheap flights is one of the keystones of the company.
Genes are expected to give offspring hereditary similarities to the parent. However, this was not known and Gregory Mendel asked himself what was passed on by parents to their offspring that is the basis for similarity. Mendel would go on through experiments with pea plants to answer short questions. The answers were short as well as to say that the passing of characteristics from parents to the offspring is throug...
Southwest Airlines strategy of focusing on short haul passenger and providing rates as low as one third of their competitors, they have seen tremendous growth in the last decade. Market share for top city pairs on Southwest's schedule has reached 80% to 85%. Maintaining the largest fleet of 737's in the world and utilizing point-to-point versus the hub-and-spoke method of connection philosophy allowed Southwest to provide their service to more people at a lower cost. By putting the employee first, Southwest has found the key to success in the airline business. A happy worker is a more productive one as well as a better service provider. Southwest will continue to reserve their growth in the future by entering select markets only after careful market research.
Economics plays a huge role in the airline industry. For Southwest, the CEO states that they kicked off a “low fare revolution” back forty-five years ago when the company began. It was their goal to make flying affordable and convenient for the average man; flying was no longer going to be just for the elite. According to CEO Gary Kelly when Southwest Airline originated “only 15 percent of Americans had traveled by plane” (The Low-Fare Revolution). That number has currently risen to more than 85 percent of the United States population, with a large part of the credit going to Southwest Airline. All of this being said, one author notes that since
Another internal challenge for Southwest Airlines is the conflicting management style and business operation with AirTran. On top of that, the external challenges such as the increase of competitions and gas prices are some of issues f...
The main purpose of this lab was to determine if the mutant genes were dominant or recessive, autosomal or x-linked, and if either gene combination was linked. Also, if they were linked, one was to determine how far apart. In this experiment, fruit flies were used to obtain a better understanding of Gregor Mendel’s genetic principles. Using the law of segregation and the law of independent assortment, one of the main objectives was to learn how certain traits were inherited while others were not and to determine if two different fruit fly crosses fit the 9:3:3:1 ratio. In the beginning of the experiment, a two vials were obtained and prepared, and following this the phenotypes and sexes were observed. In each vial, there was a cross with first
