Japans Geisha Performers and Artisans

With paper-white skin, demur red-painted lips, glorious silk kimonos and elaborate jet-black hair, Japans geisha are one of the most iconic images associated with the Land of the Rising Sun. As a source of companionship and entertainment as early as 600, these geisha were trained in many arts, including poetry and performance.   However, it wasnt until 1750 that  images of the modern geisha  first appeared in historical documents, but from then, the geisha have epitomized the essence of beauty  in Japanese artisan culture, passing down their traditions to this day. Now, modern geisha share the traditions of their short-lived heyday with artists, tourists and businesspeople alike, perpetuating the best parts of their brief prominence in Japanese mainstream culture. Saburuko: The First Geisha The first geisha-like performers in recorded Japanese history were the saburuko  Ã¢â‚¬â€ or those who serve — who waited tables, made conversation and sometimes sold sexual favors sometime during the 600s. The higher-class saburuko danced and entertained at elite social events while ordinary saburuko were mostly the daughters of families left destitute in the social and political upheavals of the seventh century, the period of the Taika Reform. In 794, the Emperor Kammu moved his capital from Nara to Heian   Ã¢â‚¬â€ near present-day Kyoto. Yamato Japanese culture flourished during the Heian period, which witnessed the establishment of a particular standard of beauty, as well as the origins of the samurai warrior class. Shirabyoshi dancers and other talented female artists were in high demand throughout the Heian era, which lasted until 1185, and although they faded from mainstream appeal over the next 400 years, these dancers continued to pass their traditions on through the ages. Medieval Precursors to the Geisha By the 16th century  Ã¢â‚¬â€ following the end of the Sengoku period of chaos — major Japanese cities developed walled pleasure quarters where courtesans called yujo lived and worked as licensed prostitutes. The Tokugawa government classified them according to their beauty and accomplishments with the oiran —  who were early kabuki theater actresses as well as sex-trade workers — atop the yujo hierarchy. Samurai warriors were not permitted to partake in kabuki theater performances or the services of yujo by law; it was a violation of the class structure for members of the highest class (warriors) to mix with social outcasts such as actors and prostitutes. However, the idle samurai of unremittingly peaceful Tokugawa Japan found ways around these restrictions and became some of the best customers in the pleasure quarters. With a higher class of customers, a higher style of female entertainer also developed in the pleasure quarters. Highly skilled in dancing, singing and playing musical instruments such as the flute and shamisen, the  geisha that began performing did not rely on selling sexual favors for their income but were trained in the art of conversation and flirting. Among the most prized were geisha with a talent for  calligraphy or those who could improvise beautiful poetry with hidden layers of meaning. Birth of the Geisha Artisan History records that the first self-styled geisha was Kikuya, a talented shamisen player and prostitute who lived in Fukagawa around 1750. Throughout the late 18th and early 19th centuries, a number of other pleasure quarter residents began to make a name for themselves as talented musicians, dancers or poets, rather than simply as sex workers. The first official geisha were licensed in Kyoto in 1813, just fifty-five years before the Meiji Restoration, which ended the Tokugawa Shogunate and signaled the rapid modernization of Japan. Geisha did not disappear when the shogunate fell, despite the dissolution of the samurai class. It was World War II that really dealt a blow to the profession; almost all young women were expected to work in factories to support the war effort, and there were far fewer men left in Japan to patronize teahouses and bars. Historical Impact on Modern Culture Although the heyday of the geisha was short, the occupation still lives on in modern Japanese culture — however, some of the traditions have changed to adapt to the modern lifestyle of the people of Japan. Such is the case with the age young women begin geisha training. Traditionally, apprentice geisha called maiko began training at about age 6, but today all Japanese students must stay in school through age 15 thus girls in Kyoto can begin their training at 16, while those in Tokyo usually wait until they are 18. Popular with tourists and businesspeople alike, modern-day geisha support an entire industry within the eco-tourism industries of Japanese cities. They provide work for artists in all of the traditional skills of music, dance, calligraphy, who train the geisha in their  crafts. Geisha also buy top-of-the-line traditional products such as kimono, umbrellas, fans, shoes, and the sort, keeping craftsmen in work and preserving their knowledge and history for years to come.

Multi Crew Pilots Licence free essay sample

â€Å"What we have to learn to do, we learn by doing. † (Aristotle, 384BC – 322BC) While the new Multi Crew Pilots Licence (MPL) embodies some good ideas, these could be implemented without creating an entirely new qualification with entirely new problems. It began when, at the request of the airlines, ICAO set up the Flight Crew Licensing and Training Panel (FCLTP) to review the system by which pilots become qualified to fly air transport aircraft as co-pilots for an airline. Some airlines believed the traditional system was outdated and irrelevant (Matschnigg, 2011). The emphasis for the solution was to be on better use of technology and better Crew Resource Management – essentially teamwork. This resulted in the creation of the MPL which was added to ICAO Annex 1 in 2006. The MPL is designed to train ab-initio students in airline procedures from the outset with increased use of simulators and overarching Threat and Error Management (TEM) and Crew Resource Management (CRM) principles. There are four phases – the core stage is conducted in a light aircraft, then the basic, intermediate and advanced stages are primarily conducted in simulators. Students are contracted to an airline from the beginning and procedures for that airline are taught throughout. Then after completing between six and twenty landings in an actual airliner the student begins initial operating experience (IOE) with their airline flying actual segments (ICAO, 2006). MPL graduates are averaging just 286 hours experience on completion of their course including 196 hours in simulators and just 15 hours as pilot in command (Matschnigg, 2011). This is an alternative to the traditional Commercial Pilot Licence (CPL) where a student completes a minimum of 200 hours in real aircraft in real environments including at least 100 hours as pilot in command experience (CAA, 2011). Progression then requires an instrument rating, a type rating and in most cases experience is gained by working in general aviation before a candidate can become a new-hire first officer. Advantages of the MPL over the CPL include safer training due to less actual flying, less pollution from simulators than real aircraft, less weather disruption to training, less noise near airports and less airspace congestion. The most controversial feature is the reduction of minimum hour requirements which Matschnigg (2011) regarded as â€Å"regulatory hurdles† and â€Å"box ticking. † A finished MPL also includes a type rating but a graduate can’t fly for any airline other than the airline they are contracted to until the IOE is complete. This caused problems for the first group of MPL students who began work for Sterling Airlines which subsequently folded before they had completed their IOE (Chandler, 2009). In this situation a student has to retrain for a CPL. One hallmark of the MPL is the high dependency on simulators. The idea that real experience is the best way to learn is not new and explains why the MPL has drawn criticism and has been dubbed the â€Å"Microsoft Pilots License†. According to Chandler (2009), the cost of running a simulator is four times less than that of running a real aircraft but supporters say that economic motivation is not the reason for the increased simulator usage. Schroeder amp; Harms (2007) claim the real motivation is to fully utilise increasingly high-fidelity simulators, although much of the training uses cheaper low-fidelity simulators (ICAO, 2006). Schroeder amp; Harms (2007) also concede that the â€Å"operations-oriented training approach could also reduce the duration and cost of pilot training. † A stronger motivation for the MPL concept is to avoid pilots reverting to the first practices they learned as student pilots flying small aircraft because some of these practices can be hazardous if reverted to in airliners (Matschnigg, 2011). Regression is a psychological defence mechanism against a difficult or frustrating experience – such as emergency situations and also training. When Comet pilots were converting to the Boeing 707 they had to learn to wait for the new aircraft to slow down on landing before reaching for the nose wheel steering. It took a lot of effort for these pilots to change this habit, and indeed it is doubtful that first-learned habits can ever be completely unlearned (Beaty, 1995; Orlady amp; Orlady, 1999). Therefore it is a commendable feature of the MPL that standard operating procedures, TEM and CRM are inherent because improved mental simulation and teamwork should decrease the occurrence of regression. However, according to Salas amp; Maurino (2010), task work should be learned before team work so the student should properly learn â€Å"stick and rudder† skills before integrating these with management theories, as the CPL already does. Another advantage of the MPL is that most instructors have airline experience which is a good way of teaching cadets good habits for their airline careers and to minimise regression. Typical CPL courses are taught by instructors with no airline experience and the MPL looks to change this, however there may not be enough instructors both willing and qualified to undertake large scale training (IFALPA, 2007). While some advantages of the MPL are clearer than others, the reduction of experience in actual aircraft has drawn justified criticism. Beaty (1995) defines learning as a change in behaviour as a result of experience. Most members of the MPL-founding FCLTP agreed that a proper MPL syllabus should include more flight hours rather than less (IFALPA, 2007). While as stated by Matschnigg (2011), it is agreed that flight hours alone are not a reliable indicator of pilot competency, experience is still proven to aid decision making in stressful situations. Low levels of experience lead to a high mental workload and therefore decreased performance (Robson, 2008). Novice pilots operate more at the Rule Based or Knowledge Based levels of performance as defined by Rasmussen (1986). These levels require more cognitive resources and take longer to facilitate a decision than the Skill Based level of performance which experienced operators are more able to utilise because any given situation is less likely to be novel to them. According to Reason (as cited by Salas amp; Maurino, 2010), the Knowledge Based level of performance has a worse than 50% error rate. Furthermore, the extra time a novice takes to come to a decision is not ideal if the situation is an emergency. Ramifications for the industry as a result of the MPL may include a loss of confidence from the public when an accident eventually occurs with an inexperienced pilot at the controls. The International Federation of Air Line Pilots’ Associations (IFALPA) believes cutting real flight hours in training will degrade safety because in an emergency both pilots can become task saturated meaning a pilot must be able to operate independently (IFALPA, 2007). One unusual occurrence illustrates how experience can also aid decision making between two pilots. On the 23rd of July, 1983 a 767 ran out of fuel flying over Canada and became the famous Gimli Glider. No published aerodromes were within gliding distance but fortunately the co-pilot once flew from an air force base near-by which was not published in airline documentation and was now decommissioned. The captain was an experienced glider pilot and was able to glide the airliner down and even side slip it on finals resulting in a successful emergency landing (Williams, 2003). Thus the pre-airline experience of both pilots resulted in good decision making and a positive outcome. Other ramifications may involve financial loss as a result of inflexible pilot rosters if some states refuse entry to MPL pilots. The MPL has advantages in the way it uses cutting edge technology and the most relevant procedures, however the proponents of the new licence have failed to convince most of ICAO’s 191 contracting states that it is a safe alternative to the traditional methods of becoming a first officer. Five years after the introduction of the MPL only 7% of ICAO states had implemented it. Notable participants are China, Australia, the UK and other European states while the notable absentee is the United States (Matschnigg, 2011). New Zealand has also abstained with Air New Zealand stating the current pilot induction process is satisfactory (Lamain, 2008). Matschnigg (2011) and Orlady amp; Orlady (1999) both predict the problem with reducing levels of experience in the right-hand seat yet the MPL appears to deliberately realise this prediction, even while the United States is moving in the opposite direction with Congress recently proposing a minimum of 1,500 hours for new-hire first officers (Karp, 2012). Therefore even while initial feedback shows MPL pilots are performing as well as pilots with traditional CPL’s (Buyck amp; Thomas, 2008; Matschnigg, 2011) the real test will be when an MPL graduate needs to assume full responsibility in a real emergency situation while they are still, ultimately, a novice operator. Then it will be seen if Aristotle was correct.

Holocaust Study Guide TYPES OF CAMPS1. One of the types of camps owned by the Nazis was concentration camps. The inmates there were forced to work under harsh conditions and starvation2. The second type of camps was actual death camps. These camps were just made to kill Jewish people and other groups who were classified as enemies of the Nazis.3. There was also a third type of camp called Red Cross camps. At these camps the Red Cross was able to come in and tend for the Jewish people there.PEOPLE INVOLVED4. There were many people who were killed in the Holocaust. Along with the Jews, non-Jewish Poles, alleged communists, political opposition, members of resistance groups, Catholic and Protestant opponents, unionists, homosexuals, physically handicapped, mentally retarted, soviet prisoners of war, Jehovah's Witnesses, anti-Nazi clergy, and psychiatric patients were all killed.5. The Nazis ran the camps and had German doctros perform tests on the prisoners.English: JW Armband

Van Der Waals Forces Definition

Van Der Waals Forces Definition Van der Waals Forces are the weak forces which contribute to intermolecular bonding  between molecules. Molecules inherently possess energy and their electrons are always in motion, so transient concentrations of electrons in one region or another lead electrically positive regions of a molecule to be attracted to the electrons of another molecule. Similarly, negatively-charged regions of one molecule are repulsed by negatively-charged regions of another molecule. Van der Waals forces are the sum of the attractive and repulsive electrical forces between atoms and molecules. These forces differ from covalent and ionic chemical bonding because they result from fluctuations in charge density of particles. Examples of van der Waals forces include hydrogen bonding, dispersion forces, and dipole-dipole interactions. Key Takeaways: Van der Waals Forces Van der Waals forces are distance-dependent forces between atoms and molecule not associated with covalent or ionic chemical bonds.Sometimes the term is used to encompass all intermolecular forces, although some scientists only include London dispersion force, Debye force, and Keeson force.Van der Waals forces are the weakest of the chemical forces, but they still play an important role in the properties of molecules and in surface science. Properties of Van der Waals Forces Certain characteristics are displayed by van der Waals forces: The forces are additive.The forces are weaker than either ionic or covalent chemical bonds.They are not directional.The forces act only over a very short range. The interaction is greater when molecules draw closer.Van der Waals forces are independent of temperature, with the exception of dipole-dipole interactions. Components of Van der Waals Forces Van der Waals forces are the weakest intermolecular forces. Their strength typically ranges from 0.4 to 4 kJ/mol and act over distances less than 0.6 nm. When the distance is less than 0.4 nm, the net effect of the forces is repulsive as electron clouds repel each other. There are four major contributions to van der Waals forces: There is a negative component that prevents molecules from collapsing. This is due to the Pauli exclusion principle.Either an attractive or repulsive electrostatic interaction occurs between permanent charges, dipoles, quadrupoles, and multipoles. This interaction is called Keesom interaction or Keesom force, named for Willem Hendrik Keesom.Induction or polarization occurs. This is an attractive force between a permanent polarity on one molecule and an induced polarity on another. This interaction is called the Debye force for Peter J.W. Debye.London dispersion force is the attraction between any pair of molecules due to instantaneous polarization. The force is named after Fritz London. Note even nonpolar molecules experience London dispersion. Van der Waals Forces, Geckos, and Arthropods Geckos, insects, and some spiders have setae on their foot pads that allow them to climb extremely smooth surfaces, such as glass. In fact, a gecko can even hang from a single toe! Scientists have proposed numerous explanations for the phenomena, but it turns out the primary cause of the adhesion is the electrostatic force more than van der Waals forces or capillary action. Researchers have produced dry glue and adhesive tape based on analysis of gecko and spider feet. The stickiness results both from tiny velcro-like hair and also the addition of lipids, which are found on gecko feet. Gecko feet are sticky because of van der Waals forces, electrostatic forces, and lipids found on their skin.

A 100-kg researcher, carrying an additional 20 kg of gear, scaled an 8 m (26 ft) glass wall using two climbing paddles. The goal is to give military personnel Spiderman-like abilities. Scientists have found a way to use van der Waals forces to help people cling to smooth surfaces, such as glass and walls.
