Free Essays on The psychological Laboratory at Leipsic

â€Å"The psychological Laboratory at Leipsic† The article, â€Å"The psychological Laboratory at Leipsic†, by James McKeen Cattell, describes the laboratory and the processes of experimentation. Psychology is different from other sciences, and philosophy, in that it uses experimentation to try and figure out why things work the way they do. An important task in a psychology students’ curriculum is that they learn the process of experimentation and why that experiment proves or disproves their hypothesis. Psychology tries to explain the connection between the body and the mind, and controlled, well-organized experiments give a good clue to what goes on. Professor Wundt, who decided to have his male students divide up into experimentor and subject groups, to have experiements done by each other, first thought up the psychology laboratory. Wundt would aid the student’s questions but lead them to find their own conclusions. Wundt also established a journal for publication of the research called â€Å"MIND†. The work at Leipsic is grouped into four sections, the analysis and measurement of sensation, the duration of mental processes, the time-sense, and attention, memory and the association of ideas. The first deals with the relationship between our senses and physical stimuli. For example, Wundt, and Fechner’s laws of constant stimuli, where for a given situation there will always be a constant number used to figure out the outcome. The duration of mental processes is related to the time reaction of reflexes and the time of sensory perception. The time-sense is how quickly or slowly our senses react to a stimulus. Finally attention, memory and the association of ideas are dealing with the mind, and how it creates and stores knowledge. This article tells the background of experiments and why they are still important in psychology today. Wundt not only started the first experimental laboratory but also created the first researc...

Art - Essay Example It would have been more natural if he had drawn soft boundaries with light pencil. Warhol has very nicely painted the nose giving shades of gray and white color very nicely. It is where he has kept his hand very light giving this feature a very original feel. The sketch is cool overall and the painter has no doubt drawn it with keen observation. I like the way the hair has been drawn and painted giving the man a sober look. The hair is not parted and is very cleverly hiding half of the ear. The collar covering the neck has also been nicely drawn giving a brief description of the man’s satire. Although, the picture is not colorful, yet the sketch is complete in itself and the color tones the painter has used seem enough for this piece of art. It is his great success that he has been able to show what age the man was, how he looked like, and his personality, using a few shades of two to three colors. In this picture, Raymond Johnson has put into abstract the sky and landscape of New Mexico and the picture tells more of his experience with the scene. Johnson was of the view that a masterpiece results from actual experience depicted in the form of painting and what counts is the internal significance of things which is an abstract quality. Something painted in abstract gives it the real life and soul. Johnson has always used two approaches to paint land. First, he would give a deep insight into his mood and experience that he had, and second, he would paint out in abstract everything giving special consideration to their forms and the manner in which they receive and emit light. The picture is a beautiful abstract form of landscape with black clouds hovering over it giving the feel of gloominess and pleasure at the same time. I like the green patches the painter has shown on the landscape and the shades of orange, pink, green and yellow give a very soothing look. The place the pai nter had in his mind must have been a piece of calm and cozy piece of land which

Legalization of Marijuana Research Paper Example | Topics and Well Written Essays - 1250 words

Legalization of Marijuana - Research Paper Example I suffered a closed head trauma that left me shaken by up to five grand mal seizures per day. I became addicted to pharmaceutical medication that did not relieve the seizures that plagued my life. About 25% of epileptics do not respond to medicines. I am one of many who do not. While the prescription drugs left me debilitated, I discovered that with marijuana I could completely control the onset of a seizure. For me this knowledge was freedom. By using it I am able to abandon pharmaceutical medication and its side effects. Arrest and acquittal In August of 1992 my husband, Mike and I were arrested for felony cultivation of five marijuana plants that I grow openly in our front yard. This crime is punishable by three years in state prison. After our arrest we realized the importance of challenging the existing laws governing the medical use of marijuana. We hoped that in presenting a necessity defense we might clarify the medicinal use of marijuana, freeing myself from further prosecut ion and establishing a precedent for patients relief. After 7 1/2 months the district attorney of Santa Cruz County, California dropped charges against me for marijuana cultivation. He stated, "No reasonable jury would find her guilty." Having won what I thought to be the right to use the only medicine that controls my seizure activity, I again planted five marijuana plants in my front garden. ... Or are we shuffled between departments? The fact is, even though there is no alternative that will provide relief for my condition, and despite my having adequately established necessity through the judiciary system, it is still illegal to use or cultivate marijuana. California State Senator Henry Mello has presented a non-binding resolution, SJR 8 in a bipartisan effort to allow the use of marijuana medicinally. There is at present no provision by the federal government to meet the needs of patients, only the remnants of the antiquated Compassionate IND (Investigational New Drug) serving nine government-approved patients exists to this day. This defunct program supplied patients with government marijuana, but the project was axed by the Bush administration in March of 1992. Research There exist three phases of study that are necessary in ascertaining the acceptability of a new drug for medical use in treatment. The FDA requires: Phase I; safety, Phase II; pilot studies on efficacy, and Phase III; controlled studies on efficacy and safety. According to Judge Francis L. Young, presiding Administrative Law Judge to the United States Department of Justice in the DEA hearings on the Marijuana Rescheduling Petition in 1988, it has been established that marijuana satisfies both Phase I, II and Phase III studies on safety and efficacy. Having demonstrated sufficient evidence to substantiate these findings it then seems redundant to continue further studies on the safety or efficacy of marijuana. By succumbing to the FDAs present acceptance of only Phase II; safety studies, we surrender ground already gained. In fact, as patients' needs are ever growing it is essential to focus on the third phase, i.e., controlled trials, if any aspect of further

Cultural Hybrids Essay Example for Free

Cultural Hybrids Essay There are many people from different countries with different cultures who want to live the American Dream. They want the idea of freedom and they feel that United States is the only country in the world who can give the people the liberty it offers. The life of a person whom no one speaks with because of one’s difference can be quite miserable. The story â€Å"This is what it means to say Phoenix, Arizona† by Sherman Alexie shows the audience how different the life of Native Americans are compared to modern day Americans. Throughout the story, details about events that happened in Victor and Thomas’s life which combines the Indian and American side of their heritage were given. Alexie was trying to tell the readers how the Indians in the reservations want to hybridize their Native American and modern American culture. Since Thomas and Victor both grew up in the reservation, they see a big difference their lives are compared to the modern day Americans. The first detail that illustrates my thesis was the Fourth of July celebration when Victor and Thomas were kids. Thomas states, â€Å"It’s strange how us Indians celebrate the Fourth of July. It ain’t like it was our independence everybody was fighting for† (16). Alexie displays how Indians try to act more Americanized in order to fit in better with the modern American crowd. Back then, no one besides their own might have spoken to them because they were different so they want to be accepted. For example, the event when they were in the airport and had talked to the gymnast, Victor says, â€Å"Everybody talks to everybody on airplanes. It’s too bad we can’t always be that way† (19). Alexie sends the readers a message of how in their minds, the only way that they were going to be liked was by forgetting their Native American culture and acting more like the modern Americans. Another factor the author provides the audience of this hybridization was through the remains of Victor’s father. Alexie writes, â€Å"They set him down carefully behind the seats, put a cowboy hat on the wooden box and a Dodgers cap on the cardboard box. That’s the way it was supposed to be† (20). The cowboy hat displays the Indian side of their heritage and the Dodgers cap conveys the American side. In this situation, Alexie provides a clear view of how the characters combine their two different cultures. It is not the fact that they are forgetting the beliefs they grew up with; they blend the two cultures together to better their lives in both nation. Next was the Spokane falls incident with Thomas and Victor’s father. Thomas utters, â€Å"He drove me over to Denny’s, bought me dinner, and then drove me home to the reservation† (20). Denny’s is an American fast food restaurant. The way Alexie combines the fact that they eat at a modern American restaurant and then goes home to the reservation once again shows the mixture of the two customs. In addition to the modern American cultures, Alexie also shows how Victor and Thomas hold on to their Native American heritage. When Thomas and Victor were kids, they had stolen a car and parked it in front of the police station. Now in the modern days, if a kid was to do this, it would be a crime and the kid would be punished. Yet the turn out for this was the exact opposite. Instead of being scolded, everyone cheers â€Å"You were very brave. Very brave† (17). They even thought of themselves as warriors. Moreover, the fact that they still call each other junior also shows a way they keep their tradition alive as Native Americans. Nowadays, people do not often call each other with respect. They just call a person by their name no matter the age. The Native Americans, on the other hand, gives the people who are older a term that shows respect. Thomas states, â€Å"Everybody on this reservation is named Junior† (17). Victor and Thomas were two of the youngest people that live in the reservations therefore everyone to them are called Junior. It is a symbol for elderly. Alexie uses Victor and Thomas Builds-the-fire as the representation of these two cultures. Thomas is the person who sticks to the old fashioned, Native American values while Victor illustrates the modern day Americans and wanting to fit in. Thomas is more traditional. He demonstrates the old Native American beliefs. Victor, on the other hand, lives in the present. Both holds on to their Native American beliefs while also trying to grasp the modern American traditions. Alexie clearly represented the hardships the Native Americans have had living in the poor reservations by using details about Thomas and Victor’s life growing up. Being judged at by the way a person is or what culture they came from is a big reason why Victor and Thomas, but mostly Victor, try to act more like the modern day Americans. Although some traditions were forgotten as they grew up, in many ways, they still held on to the fact that they are still Native Americans. Some events in their life displays Victor and Thomas turning away from their culture but still is able to remember it. No matter where a person is or who they communicate with, a culture one grew up with can never be easily forgotten.

Constraints Facing The African Stock Market Economics Essay

The African stock market is going progressively sophisticated in pricing, insulating and reassigning hazard. Tools such as derived functions and securitization contribute to this procedure but pose their ain hazard. The failure of accounting and ordinance to maintain abreast of development introduces more hazard with on occasion dramatic effects.Macroeconomic FactorsMacroeconomic hazards include rising prices hazard, involvement rate hazard, low modesty and thin fiscal market which all together affect the public presentation of a stock market. Macroeconomic policy has a great impact on the public presentation of the stock market. In 1996, the Zimbabwe stock market which accounted for an overall public presentation of 86.5 % . However, in 1997 its public presentation decreased by more than 50 % in the aftermath of dramatic authorities farm and to pay $ 240 million in pensions to veterans of Zimbabwe independency war. For the last two decennaries, the growing rate of existent per capita end product for Africa has been negative, while other parts have been demoing strong positive growing rates. For illustration, while between the 1970s and 1990s East Asia and South Asia moved from an mean growing rate of 4.6 per centum and 0.7 per centum to 6.4 per centum and 3.3 per centum, severally, Sub-Saharan Africa ‘s growing rate declined from 0.5 per centum in the 1970s to -0.4 per centum in the 1990s.Corporate AdministrationCoup vitamin D ‘ & amp ; eacute ; cheapnesss is rather celebrated in African history. It appears that constitutional regulation are present at that place and politicians are pull stringsing fundamental laws to either seek thirster footings in office or perpetuate their stay. Therefore, there is a deficiency of good corporate administration in the states. In the absence of corporate administration, there is inappropriate policy taken by the authorities and regulative models. Furthermore, there is no control of corruptness, capacity edifice, and there is an uneffective, inefficient, no transparent and accountable system for mobilising and apportioning public every bit good as private resources.High unemploymentIn Africa, there is copiousness of unskilled labour and this may take to worsen of the on the job category. The growing in demand for skilled labour does non fit the diminution of unskilled and semi-skilled occupations. The labour market is switching towards more skilled workers, professionals and directors. A labour study in South Africa found that there is more demand for directors in the populace sector, particularly local authorities and peculiar services sectors Unemployment is pig-headedly high and edging upward. In South Africa the expanded unemployment rate is estimated to be every bit high as 40 % with the official rate at about 29 % . The fact that the labour market is biased against those with less accomplishment is reflected in the higher mean wage additions for skilled individuals.Trade DevelopmentMany African states are faced with a multiplicity of challenges that prevent them from take parting in the planetary economic system and harvesting the benefits of increased globalisation. Africa is the most disconnected continent. Fourteen states are landlocked, accounting for 30 % of Africa ‘s population. The roots of the job prevarication in chronic restraints to competitiveness including, hapless substructure, little and disconnected markets, undeveloped fiscal markets, weak systems to ease trade, weaknesses in cardinal establishments, and the deficiency of equal human resources.Political HazardPolitical instability, institutional incapacity and societal unrest inhibit foreign capital influxs. These in bend lower investing appetencies and have a negative impact for economic chances and investing clime. Percepts of political hazard originating from peculiar events, such as those related to the recent elections in Kenya which generate market volatility and discourage investing. Africa is seen as a part of high political hazard, and important hazard premium are demanded by equity investors, loaners and insurance companies.Currency fluctuation hazardThe planetary economic lag in universe growing may impact African exports of agricultural merchandises, minerals and hydrocarbons. Africa ‘s dependance on natural resource exports has made many states vulnerable to trade good monetary value dazes that are outside their control. Sudden additions in export grosss or import costs can do currency instability and budget uncertainness. Furthermore, there is strong grounds that currency depreciation has negative consequence on the public presentation of the African stock market.Crisis of International ConfidenceMany states in sub-Saharan Africa enjoyed robust economic growing in recent old a ges. However, the nutrient and fuel monetary value dazes of 2007-08 that preceded the current planetary fiscal crisis weakened the external place of net importers of nutrient and fuel, caused rising prices to speed up, and dampened growing chances. A research done by IMF shows that in the yesteryear a 1 per centum point lag in planetary growing has led to an estimated ? per centum point lag in sub-Saharan African states. But the effects may be more marked this clip because the tightening of planetary recognition compounds the impact of the lag, worsening hazards for trade finance and other capital flows.Recommendations.The stock market needs specific attending when it comes to the menaces and challenges predominating. Normally, there are several ways which can take to the development of the stock market. Automation can be of great aid as it reduces costs every bit good as inefficiencies. It operates faster than the manual system which besides increases trading activities and liquidness. We besides have demutualization which is a procedure that involves a alteration in ownership construction and a alteration in legal and organisation signifier. Factors such as competition among exchanges, demand for increased capital, demand for good corporate administration in exchanges and the impulse to open up ownership of exchanges to public investors help demutualization addition popularity. Demutualization is expected to work out common construction jobs by opening up merchandising rights, acknowledging new trading spouses, and broadening ownership such that the populace can put in exchanges. It besides increases entree to services of the exchange and removes inordinate investing costs for fund holders. Another cardinal solution can be to beef up Financial Regulation and Supervision. Such a step will hike the assurance of investors every bit good as protects their rights and hence besides encourages them to put more in the stock market. The development of good quality establishments can besides impact the attraction of equity investing and lead to stock market development. Good quality establishments such as jurisprudence and order, democratic answerability, bureaucratic quality are of import determiners of stock market development in Africa because they cut down political hazard and heighten the viability of external finance. The increased engagement of investors on the stock market will besides assist advancing efficient market patterns and fiscal invention. They typically favor greater transparence and market unity in both primary and secondary markets, seek lower dealing cost, and promote efficient trading and colony installations. Enhancing surveillance of the OTC forex derivative markets by systematic processing and analysis of information on offshore activity will besides be of great aid. Another proposed solution to jobs faced by African stock markets is to incorporate stock exchanges. Unifying African stock markets into a individual regional exchange instantly is no uncertainty an ambitious and dashing undertaking, given the associated institutional and fiscal cost complexnesss. Advocates of this proposition argue that a good incorporate regional stock exchange in Africa will be a powerful beginning and driver of capital flows to Africa. Such an exchange will besides, if good structured, work out the current jobs of illiquidity, little size, and atomization.

5 Questions Every Job Hopping Nurse Should Know How to Answer

5 Questions Every Job Hopping Nurse Should Know How to Answer The workforce is experiencing a somewhat generational shift in terms of job longevity at the moment- where the Baby Boomers had stability, the Gen Xers are in the middle of their careers, and Generation Yers are following their bliss. All these can lead to some â€Å"diverse† resumes. Maybe you came out of school and landed first at a hospital you hated; maybe you’re constantly in pursuit of the next best thing; or maybe other circumstances affected your job stability. Whatever your situation, you might be worried about how an employer will perceive a gap or frequent changes in your resume. Here are the 5 questions you should prepare to answer in any job interview- nail this, you’ll soothe any employers worried brow.1. How often are you changing jobs?An interviewer will see a yearly shift very differently than a new position every six months or less. Be able to articulate what you got out of each job before you left it and how what you learned will serve you well in the open position.2. Are you changing positions or just employers?Shifting positions within the same hospital, office, or institution shows that you’re expanding and developing your experience- changing employers that often shows you struggle to get along with people or don’t know how to improve workplace relationships. Look for different positions within the same group first if you need a change.3. How long have you been a nurse?You don’t want to seem impulsive or like this was an accidental career move. If you’re just beginning, try to avoid job gaps or short-term job hopping when you can, to sidestep these questions all together.4. What are your career goals?Does your resume reflect a systematic move from one specialty to another? Or are you moving more or less randomly from one available job to another? Have a 1-, 5-, and 10-year plan in your pocket, ready to bring up in any interview that might ask.And lastly, but most importantly:5. Why did you change jobs?Be able to account for the professional moves you made. Did you change for professional or personal reasons? Were you in search of a better opportunity or running away from a difficult situation? Even if you did jump ship because a work environment was toxic, do you have a diplomatic, growth-centric answer ready? Did you pursue positive solutions and wait for improvement? Did you understand your employer’s expectations? Did they appreciate your goals?See yourself as an investment- because that’s how your employer will see you- and be able to present yourself as a low-risk, high-reward prospect. That’s what any interviewer hopes to find!

The History and Development of Inline Skating

The History and Development of Inline Skating There are historic ice skating relics that date back as far as 3000 B.C. But,  inline roller skates probably originated much later in Scandinavia or Northern Europe where ice skating was an easy way to travel short distances. By the early 17th century,  these early Dutch  called themselves skeelers  and skated on frozen canals in the winter. They eventually used a primitive form of roller skate, made by attaching wooden spools to a platform to allow similar travel in warmer weather. The first officially documented inline skate actually appeared in London in 1760. The progression from transportation to a substitute for on stage ice skating, to recreational skating, to fitness skating and eventually to inline competitive sports has been closely linked to the development of inline skate technology. Lets follow the developments and technological improvements that have been made to the original inline skates that lead to the comfortable and sometimes highly specialized equipment used by inline skaters today. The  National Museum of Roller Skating  was the source for many  of the historical facts in this article. 1743 The first documented reference to inline or roller skating was left by a London stage performer. The inventor of these skates, which were probably an inline design, is unknown and is lost in history. 1760 The first known inventor of an inline roller skate was John Joseph Merlin. Merlin was born on September 17, 1735, in Huys, Belgium. He grew up to become a musical instrument maker and accomplished mechanical inventor. One of his inventions was a pair of skates with a single line of small metal wheels. He wore the skates as a publicity stunt to promote his museum, and from the beginning, stopping was a problem. It is believed that one of his ballroom stunts ended in a dramatic crash into a mirrored wall because of this defect. For the next century, roller skate wheels followed the inline design alignment. 1789 The inline skate idea made its way to France in 1789 with Lodewijik Maximilian Van Lede and his skate that he called the patin a terre which translates from French to â€Å"land skates† or earth skates. Van Ledes skates consisted of an iron plate with wooden wheels attached. He was a sculptor at the Academy Bruges in Paris and was considered as very eccentric. In 1819 the first inline skate was patented and inlines remained until 1863 when skates with two  axles  were developed. These quad skates allowed more control and their popularity spread quickly in North America and Europe. The four-wheeled quad skate quickly dominated the skate manufacturing industry. Some companies continued to design skates using wheels in a line, but they were not taken seriously. 1818 In Berlin, Germany, inline roller skates were used in a ballet for ice skating moves when it was impossible have ice on a stage. The ballet called Der Maler oder die Wintervergn Ugungen: â€Å"The Artist or Winter Pleasures†. Ice skating was one of the winter pleasures simulated by roller skaters. No one knows what kind of skates were used. 1819 The Petitbled, the first roller skate patented, was an inline. This patent was issued in Paris, France, in 1819. M. Petitbleds invention had three inline wheels which were either wood, metal or ivory. He thought his inline skate would allow a skater to simulate ice skating moves, but the wheel construction did not allow it, and the wheels kept slipping on hard surfaces. 1823 Robert John Tyers, a London ice skater, patented a skate called the Rolito with five wheels in a single row on the bottom of a boot. The center wheels were larger than the wheels on either end of the frame to allow a skater to maneuver by shifting his weight, but the Rolito could not follow a curved path like inline skates today. 1828 Another roller skate patent was issued in Austria in 1828 to August Lohner, a Viennese clockmaker. Until then, all designs had been for inline skates, but this version was like a tricycle, with two wheels in back and one in front. He also added a ratchet to prevent the skate from rolling backward. In France, Jean Garcin got a patent for the Cingar. The name was created by reversing the syllables of his last name. The Cingar was an inline skate with three wheels. Garcin opened a skating rink, taught skating and even wrote a book called  Le Vrai Patineur  (The True Skater). Garcin had to close his rink because of the number of  skating injuries  to patrons. 1840 Monsieur and Madame Dumas, professional dancers, led a performance of fancy roller skating at Paris’s Port Saint Martin Theatre in 1840. The Corse Halle Tavern, near Berlin, featured barmaids who served the patrons on roller skates. This was needed due to the large size of beer halls in Germany at this time. 1849 The first successful use of a skate with wheels in a line was recorded in 1849 by Louis Legrange, who built them to simulate ice skating in the French Opera, Le Prophete.  These skates had major  problems because the skaters who used them could not maneuver  or stop.   1852 English J. Gidman applied for a patent for roller skates equipped with ball bearings. He had to wait 30 years to see them in use on skates. 1857 Public roller skating rinks opened in the Floral Hall and in the Strand of London. 1859 The Woodward skate was invented in London in 1859 with four vulcanized rubber wheels on each frame for better traction than iron wheels on a wooden floor. Like the Rolito, these skates had middle wheels that were bigger than the end wheels to make it easier to turn, but this did not fix maneuvering problems. This skate was used by Jackson Haines, the founder of modern figure skating, for exhibitions. 1860 Reuben Shaler, an inventor from Madison, Connecticut, developed a skate designed to solve the maneuverability problem. Shaler patented a Parlor Skate, the first roller skate patent issued by the U.S. Patent Office. This skate had four wheels attached by pins to a hanger which resembled todays inline frames. They offered a rubber or leather ring on the wheels to allow them to grip the skating surface. These inline skates never caught on. 1863 James Plimpton initiated  quad roller skate history. When he invented quad skates, they provided greater control than the inline models and were much easier to use. Plimpton put one pair of wheels in front and another in back. He put the wheels on pivots, so they could turn independently of the frame and inserted rubber cushions, so skaters could lean in the direction of their turns. 1866 The first Plimpton skates clamped on to the shoe, but improved designs used straps with buckles instead. Plimpton installed a skating floor in his furniture business in New York, leased skates to customers, founded the New York’s Roller Skating Association, introduced skating proficiency tests, operated roller rinks in the Northeast, and traveled to give lessons. Four years later, the proficiency test medals were being given out in 20 countries where Plimpton skates were used. 1867 Jean Garcin’s Cingar skate had a brief revival at the 1867 Exposition Universelle in Paris. But, eventually all inline roller skates became obsolete after Plimpton’s â€Å"quad† skate became popular. 1876 William Bown patented a design for roller skates wheels in Birmingham, England. Bown’s design made an effort to keep the two bearing surfaces of an axle, fixed and moving, apart. A toe stop design that helped skaters stop rolling by tipping the skate down at the toe  was patented. Toe stops are still used today on inline figure skates and on most quad skates. 1877 Bown worked closely with Joseph Henry Hughes, who patented the elements of an adjustable ball or roller bearing system similar to the system used in today’s skate and skateboard wheels. 1884 Levant M. Richardson secured a patent to use steel ball bearings in skate wheels to reduce friction, and allow skaters to increase the speed with minimum effort. The invention of pin ball-bearing wheels allowed skates to roll with ease and made skating shoes weigh less. 1892 Walter Nielson of New York got the patent for a â€Å"Combined Ice and Roller Skate.† His 14-wheel skates had a patent inscription that suggested that â€Å"a pad of rubber, leather, or like material should be placed ... so that when the skater desires to stop, it is only necessary to press the pad ... against the floor or ground.† This suggestion for stopping pads was ahead of its time. 1884 Levant M. Richardson  gets a patent  for steel  ball bearings  in skate wheels. These bearings reduce friction, so skaters can go faster with less effort. 1898 In 1898, Levant Richardson started the Richardson Ball Bearing and Skate Company, which provided skates to most professional skate racers of the time. The end of the nineteenth century and the early years of the twentieth century marked the appearance of cycles-skates with structures similar to modern skates online. They were invented in response to a need to skate on all types of surfaces and were the first step in the development of all-terrain skates using rubber wheels or tires. Later in the century, modern inlines emerged. 1900 The Peck Snyder Company patents an inline skate with two wheels in 1900. 1902 Over 7,000 people attended opening night at the Coliseum public skating rink in Chicago. 1905 John Jay Young of New York City creates and patents an adjustable length, clamp-on inline skate. 1910 The Roller Hockey Skate Company designs a three-wheeled inline skate with a leather shoe and the rear wheel raised to allow the skater to pivot on the center wheel. This inline was made for roller hockey by the Roller Hockey Skate Company of New York City in 1910 with boots from the Brooks Athletic Shoe Company. 1930s The Best-Ever Built Skate Company manufactures an inline skate with three wheels positioned close to the ground. The original patents for Jet inline skates for ice cross-training were filed in the 1930s. An advertisement for them was published in a 1948 issue of Popular Mechanics. 1938 Christian Siffert, of Deerfield, Illinois, patents a design for an inexpensive inline skate, which could not only be used on sidewalks but also convert to sharp-edged wheels, on ice. The Jet Skate, the ad claims, is the only skate with brakes to stop quick. This claim was probably false since at that time several brakes had been invented and patented for roller skates. The Jet Skate brake looked a lot like todays heel brakes and was designed to be used the same way. Brakes have always been a design problem for skate manufacturers. 1941 Modern inline skates begin to appear in the Netherlands. 1953 The first U.S. patent for modern inline skates, created to behave like ice runners with individually sprung and cushioned wheels, was granted under patent number US 2644692 in July 1953 to Ernest Kahlert of Santa Ana, CA.  They appeared in the April 1950 issue of Popular Mechanics and in the April 1954 issue of Popular Science. An inline skate with 2 round, artificial rubber wheels, and no brake was developed by Rocker Skate Company in Burbank, California. It was advertised in â€Å"Popular Science† in the November 1953 issue and in â€Å"Popular Mechanics† in the February 1954 issue. The ads described them as quiet, fast and good for stops and turning. 1960 The Chicago Skate Company tries to market an inline skate similar to todays equipment, but it was shaky, uncomfortable and the brakes were not dependable. A USSR inline skate was made in 1960 with 4 wheels and a toe stop. It appeared to have solid construction and is similar to some of the current inline figure skates with wheel-shaped, front-mounted toe stops. 1962 A heavy-looking inline skate called the Euba-Swingo was manufactured by the Euba company in Germany. This skate was available permanently mounted to a boot or as a clamp-on skate. Euba-Swingo skates were rockered, had a front-mounted toe-stop and were used for dry-land figure skating training. Inline skates also made an appearance in the Russian movie КÐ ¾Ã'€Ð ¾Ã »Ã µÃ ²Ã ° Ð ±Ã µÃ ½Ã ·Ã ¾Ã ºÃ ¾Ã »Ã ¾Ã ½Ã ºÃ ¸ (1962) at about 9m23s into the film.   1964 An advertisement in a magazine shows BiSkates, another inline skate intended as an alternative for ice training. 1966 The Chicago Roller Skate Company manufactures their inline skate with a boot. The inline skate which influenced Scott Olson was a 1966 Chicago Roller Skate Company skate. These skates featured four wheels in a line with the front and back wheel extending beyond the boot like an ice skate blade, and they played an important part in the development of inline skating.In Germany, Friedrich Mayer obtained a patent for his inline skate. No one was interested at the time, because of the popularity of quad roller skates, featuring two wheels per axle, a canvas shoe and a stopper in the front.In England, the Tri-Skate developed, a skate with three wheels, high leather shoes and a stopper in front, and according to Dutch articles on this topic, as many as 100,000 pairs of inline skates (not necessarily all Tri-Skates) were sold in Holland and neighboring countries. This happened before the development of  RollerBlade  and should be considered a great success. The details of Tri-Skate origi ns are uncertain. The design is either American or Dutch, the frames were made in England by Yaxon (a toy producer) and the figure boots were made in Italy. This means that the skates were sold in those countries, too. 1972 In 1972,  Mountain Dew attempted to sell  Mettoys  Skeeler in Canada. This  three-wheeled inline skate  was developed for Russian hockey players and speed skaters. The Skeelers, another name for skating or skater,  were early versions of today’s inline skates and were produced in adult and childrens  sizes. Celebrities who tried them as publicity stunts included  dancer Lionel Blair and runner Derek Ibbotson, who had set a world record for the mile in 1957. 1978 Speedys, a product of SKF, were an inline skate that featured soft boots, a frame, and four wheels. Unfortunately, the late 70s market was not ready for inline sports and the production was discontinued. 1979 Scott and Brennan Olson, brothers and hockey players from Minneapolis, Minnesota, find a pair of Chicago inline roller skates and begin redesigning them using modern materials. They add polyurethane wheels, attach the frames to ice hockey boots, and add a rubber toe-brake to the new design. The modifications were intended for ice hockey training when ice is not available. After over 200 years of trial and error, inline skating is ready to emerge. 1980 Scott and Brennan Olson established Oles Innovative Sports which became  Rollerblade, Inc.  after selling inline skates with no brake at all to the hockey players who were the early adopters. The Olson brothers introduced a new skating phenomenon that has never been equaled in roller sports history. The proper term to use when describing this skating is inline roller skating or inline skating, but Rollerblade made such an impact that the name has become synonymous with the sport in spite of the fact that Rollerblade is an inline skate manufacturer. The modern style of inline speed skates was developed as an ice skate substitute and used by a Russian athlete training on dry land for his Olympic long track speed skating events. A photo of American skater Eric Heiden using Olsons skates to train for the 1980 Olympics on a road in Wisconsin was published in  Life magazine. The Olson brothers adopted and adapted the Chicago inline design over the years, and caused a public attraction to roller skating that has been hard to match in the sport’s history. The name Rollerblade has become inline skating to most people, overshadowing many other inline skate manufacturers and leaving out a lot of the previous history of roller and inline roller skating. 1982 In 1982, Scott Olson adds the toe stop to his inline skate but found that it didnt work well. 1984 In 1984, Scott Olson adds a heel brake to help beginners get over the fear of being unable to stop. Minneapolis businessman Bob Naegele, Jr. purchased Olsons company, and it eventually became Rollerblade, Inc. This was not the first company to manufacture inline skates, but Rollerblade expanded inline skating to include more than just hockey players by offering comfortable skates with dependable, easy-to-use brakes. This introduced millions to inline skating sports. 1986 Rollerblade, Inc., begins to market skates as fitness and recreational equipment. 1989 Rollerblade, Inc. produced the Macro and Aeroblades models, the first skates fastened with three buckles instead of long laces that needed threading. 1990 Rollerblade, Inc. switched to a glass-reinforced thermoplastic resin (durethan polyamide) for their skates, replacing the polyurethane compounds that were previously used. This decreased the average weight of skates by nearly fifty percent. In 1990, inline skate developers once again turned to efforts to find designs and materials that would allow skaters to simulate more of the ice and quad roller figure and dance skating maneuvers. Roller skaters discovered the competitive advantages of inline skates, especially increased speed. Skate designers also began to explore wheel sizes and frame alignment. However, the majority of the development during this decade was intended for ice hockey and ice speed cross-training for skaters 1993 Rollerblade, Inc. developed the  ABT  or  Active Brake Technology. A fiberglass post was attached at one end to the top of the boot and at the other end to a rubber-brake and hinged to the chassis at the back wheel. The skater had to straighten one leg to stop, driving the post into the brake, which then hit the ground. Skaters had already been tilting their foot back to make contact with the ground, before ABT, so this new brake design improved safety. Pat McHale secures the United States and European patents for  a multi-purpose inline skate in 1993. This skate design features offset inline wheels that create an inside-outside edge with lateral stability for control of edges that are similar to ice blades. In 1993, two other inventors, Bert Lovitt, and Warren Winslow work together to invent an all-terrain skate that uses 2 angled wheels. 1995 The Italian firm Risport introduced the 3-wheeled â€Å"Galaxie† figure frame and an entry-level cheap 3-wheels inline figure skate all-plastic: â€Å"Kiria† in white and â€Å"Aries† in black. Another model with a metal frame and plastic boot was called â€Å"Vega†. All of these inline skates were designed with toe stops. Risport also discovered that a flat 3-wheeled frame can behave as a rockered frame just by using a much harder wheel in the center, thus splitting unevenly the skater’s weight among them. Sporting goods company K2, Inc. comes up with a soft boot design which in most aspects of the sport (except Aggressive Skating) has become the most common design. This company also heavily promotes the soft boot design for fitness. By 2000, most skate manufacturers followed suit, although the hard boot is still preferred by aggressive skaters. Diederik Hol sees a bulletin board announcement that Dutch manufacturer offers a six-month research training into designing a clap skate. He saw an opportunity to develop something with the potential of setting new world records, and he used the project as a springboard for his career in design engineering. He graduated having worked on the Rotrax skate, a multiple-hinge frame that ensures a more powerful push-off and thus higher speed. John Petell, President of Harmony Sports Inc., contacts Nick Perna, a PSA master rated coach, to test a retrofit product they called the PIC. The PIC ® device attached to conventional inline skates to enable figure skaters to perform figure skating moves requiring a toe pick that was not otherwise possible on conventional inline skates. A French inventor named Jean-Yves Blondeau gets a patent for his 31-wheeled Rollerman suit (also known as the Wheel Suit or Buggy Rollin) in 1995. This suit is designed with wheels that are very similar to inline skate wheels carefully placed on most of the major joints of the body, on the torso and even on the back. 1997 Inline skates and skating accessories become a billion-dollar international industry, with nearly 26 million Americans participating. Lovitt Winslow file their first Patent Application for their all-terrain skate invention with 2 angled wheels. 1998 The collaboration between Nick Perna and John Petell results in the development of a  rockered  inline figure skate frame.  The final patent for the PIC skate was published on April 14, 1998. A total of  23 claims were granted by the patent examiner, but the key element to the PICand other similar skates is the toe pic angle which closely mirrors the pick angle on ice skates.  The jagged metal toe picks on ice skates are used to spike jumps  and assist footwork, and this inline skate has the same capabilities via the patented PIC.   The Rollerblade Coyote  skate was introduced in 1997 as the first true off-road skate in the industry. The air-filled tires were designed for shock absorption, traction, and terrain versatility. 1999 Lovitt Winslow incorporate the new LandRoller company to manufacture and market their new skates with angled wheels. Sportsline International offers Diederik Hol a chance to design a whole new product line of skates. After less than a year of dedicated thinking and drawing concepts, he designed what is now known as the Mogema Dual Box. 2000 Inline figure skating develops as an off-ice training tool for ice skaters and emerges as a competitive event in roller sports. Some manufacturers, like Triax/Snyder, respond by providing equipment options needed for figure skating. 2002 In November of 2002, after the first World Inline Figure Skating Championships in Germany, the coach of Chien-Hao Wang visits Arthur Lee to discuss damage to Wangs inline skates and request the development of a better inline figure skating frame. Three years after he made his first sketch, Diederik Hol convinces the Rollerblade World Team and others to use Mogemas at the World Inline Championships in France. 45 skaters won their gold, silver, and bronze medals on Mogemas. 2003 The prototype for Arthur Lees Snow White  Inline is complete. 2004 Snow White sponsors two Taiwanese skaters, Chia-Hsiang Yang and Chia-Ling Hsin, for the 2004 World inline Championships in Fresno, CA. Kadu, coach of  Gustavo Casado Melo  and Adrian Baturin, and Ms. Yasaman Hejazi, coach of the Iran Inline Figure Skating Federation, are among the first coaches to use Snow White frames. 2005 LandRollers  Angled Wheel Technology  breaks away from traditional inline designs with two large, side-mounted, out-of-line angled wheels that roll astride the centerline of the boot and maintain a low center of gravity. 2006 Wheel Anti-Reversing Technology was developed by Bruce Honaker to help new inline skaters by allowing them to keep both skates on the ground, and parallel to each other. This creates comfort and stability as momentum is gained. Fear of rolling backward on inclines is also eliminated. The device may be removed after skating skills develop. 2013 Brian Green and the  Cardiff Skate Company  offer an adjustable skate with a unique three-wheel configuration and braking system that is promoted as being more stable and more convenient than any other skate on the market. Flex Brake,  Ben Wilsons lightweight braking system  designed to fit most inline speed skates or fitness skates, Alex Bellehumeurs  DXS  Inline Skating Disk Brake  system  and  Gravity Master  calf activated  brakes from  Craig Ellis revive interest  in inline skate stopping technology.

Significant Historical Event that Occurred Between 1945 and 2008 Essay

Significant Historical Event that Occurred Between 1945 and 2008 - Essay Example That the event continues to be memorable is also indicated in the work of Persbacher (2005). According to Persbacher (2005), the events of 9/11 are even in the consciousness of the religious who made the event as a point for personal and theological reflections. Five years after 9/11, Persbacher (2005, p. 96) noted that religious groups reflected on the event and expressed that â€Å"religious faith affects reactions to horrific events† and that â€Å"horrific events affect religious faith† as well. Some of the more important events immediately after 9/11 had been recorded by the Migration Policy Institute. On 17 September 2001, the Immigration and Naturalization Service increased from 24 to 48 hours the length of time a non-citizen can be detained without charges (Migration Policy Institute, 2003). On 19 September 2011, Attorney General John Ascroft presented to President George Bush the administration’s proposed anti-terrorist measures (Migration Policy Institu te, 2003). At least 480 persons were arrested by the end of September 2011 for various charges related to the 9/11 bombings and the figure increased to 1,000 around October (Migration Policy Institute, 2003). On 1 October 2011, President George W. ... 2). On 31 October 2001, US Attorney General Asroft recommended to the US Secretary of State 46 groups for inclusion in the list of â€Å"terrorist organizations† under the provisions of the US Patriot Act (Migration Policy Institute, 2003, p. 3). Indeed, from these alone, it is easy to conclude that 9/11 directly and significantly affected American lives. Along the way, we also discuss how 9/11 affected the lives of all people in the world today. Versions and Interpretation of 9/11 Tamney’s (2004, p. 599) documentation of the 9/11 are as follows. On 21 September 2001, men inspired by Islamic convictions â€Å"hijacked four passenger planes flying over the United States.† Tamney (2004, p. 599) continued that â€Å"three of the four planes were crashed into the Pentagon in Washington D.C. and the twin towers of the World Trade Organization in New York City.† According to Tamney (2004, p. 599), â€Å"at least three thousand people died as a result of these a ttacks.† Tamney (2004, p. 599) pointed out that soon after, Journalist Oriana Fallaci published The Rage and the Pride in which â€Å"she argued that the terrorist attacks expressed the essence of Islam, that most Muslims were happy about the attack, and that Muslims are out to destroy the West.† According to Tamney (2003), Fallaci’s book became a bestseller in Italy and France and was soon published in the United States in 2002. Many believe that the terrorist attack on 11 September 2011 was successful because the attack has been a surprised. However, Dahl (2008, p. 19) consider this as a conventional wisdom that must challenged: more often investigations showed that the â€Å"warnings have been available but were either misunderstood or ignored.† According to
