How to Become an Optician

How to Become an Optician There’s a famous episode of The Twilight Zone where a stressed man survives a nuclear apocalypse, and is thrilled to be left alone with nothing to do but read great books, only to have his essential reading glasses broken beyond repair. If you’re familiar with it, or you depend on your glasses and contact lenses, you might be extra thankful for your optician. Opticians are healthcare professionals who work with ophthalmologists, optometrists, and patients to make sure that glasses and contact lenses are exactly as prescribed and customized for the patient. Opticians are key players in helping us see the world clearly. Here are some information on how to become an optician. The Day-to-DayOpticians, also known as dispensing opticians, work in medical offices or retail stores. They take a vision prescription from a doctor (typically an optometrist or an ophthalmologist) and work with the patient to find and fit the correct eyewear. They may also perform eye tests that help the ophthalmologist determine a patient’s prescription. Once the prescription is established, the optician is usually the one to help the patient select and fit glasses or contact lenses, educate patients on follow-up care, and manage patient records. Informally, the optician may be able to provide you with good insight into whether that pair of glasses looks good on you, but formally he or she can also make sure that your prescription is accurate, that everything fits comfortably, and that your eyewear works with your lifestyle and needs. They serve an essential role in vision healthcare.Opticians typically work standard 40-hour workweeks, but this may include evenings and weekends, especially in retail eye clinics and stores. Also, because of the retail component, customer service is often a big part of the job.For more on what it’s like to be an optician, check out these videos:An Optician’s Main FocusOptometrist vs Ophthalmologist vs OpticianThe Requirement sBecoming an optician doesn’t require a specific four-year degree. Many enter the field with a high school diploma, though some have an Associate’s degree or a certificate from a community or technical college. On-the-job training is more of a focus in this field than a specific degree. About half of U.S. states require that opticians are licensed, so be sure to check your own state’s requirements.Opticians should have strong skills in customer service, management, communication skills, math, and basic anatomy.The PayAccording to the Bureau of Labor Statistics (BLS), opticians earn a median salary of $34,280, or $16.48 per hour.The OutlookThanks to our electronic devices causing eye strain for the foreseeable future, the future is bright for opticians. The BLSÂ  expects demand for opticians to grow by 24% by 2024.

Biography of Leonhard Euler, Influential Mathematician

Biography of Leonhard Euler, Influential Mathematician Leonhard Euler (April 15, 1707–September 18, 1783) was a Swiss-born mathematician whose discoveries greatly influenced the fields of mathematics and physics. Perhaps the best-known of Eulers findings is the Euler identity, which shows the relationship between fundamental mathematical constants and is often called the most beautiful equation in mathematics. He also introduced a notation for writing mathematical functions that is widely used today. Fast Facts: Leonhard Euler Occupation: MathematicianKnown For: The Euler identity, the function notation, and numerous other discoveries in mathematicsBorn: April 15, 1707 in Basel, SwitzerlandDied: September 18, 1783 in St. Petersburg, RussiaEducation: University of BaselParents’ Names: Paulus Euler and Margaretha BruckerSpouses Name: Katharina Gsell Early Life Leonhard Euler was born in Basel, Switzerland. He was the first child of Protestant minister Paulus Euler and Margaretha Brucker. In 1708, one year after Euler was born, the family moved to Riehen, a suburb a few miles from Basel. Euler grew up in the parsonage at Riehen with his two younger sisters. During Eulers early childhood, he learned mathematics from his father, who had an interest in mathematics and had taken courses with the notable mathematician Jakob Bernoulli while studying to become a theologian. Around 1713, Euler began attending a Latin grammar school in Basel, but the school did not teach mathematics, so Euler took private lessons. University In 1720, Euler entered the University of Basel at just 13 years old- an accomplishment that was not uncommon for the time. At university, he studied with Johann Bernoulli, Jakob Bernoulli’s younger brother, who gave Euler mathematical problems to solve each week and encouraged him to read advanced math textbooks. Bernoulli even offered to answer Euler’s math questions every Sunday afternoon, even though he was too busy to give him private lessons. In 1723, Euler completed a master’s degree in philosophy and began studying theology, as his parents had wanted. However, Euler was not nearly as excited about theology as he was about mathematics. He obtained his father’s permission to study mathematics instead, possibly with the help of Bernoulli. Euler finished his studies at the University of Basel in 1726. In 1727, he submitted an entry for the Grand Prize of the Paris Academy of Sciences concerning the optimal placement of masts on a ship. The first prize winner was an expert in the mathematics of ships, but Euler, who had not seen a ship before, won second place. Academic Career Euler was offered an academic appointment at the Academy of Sciences in St. Petersburg, Russia. He moved there in 1727 and stayed until 1741. Although Euler’s post initially involved teaching the physics and math of physiology, he was soon appointed to the mathematics-physics division of the Academy. There, Euler advanced through different positions, becoming a professor of physics in 1730 and the senior chair in mathematics in 1733. The discoveries Euler made in St. Petersburg catapulted him to world fame. Euler married Katharina Gsell, a painter’s daughter, in 1733. Together, the couple had 13 children, five of whom survived to adulthood. In 1740, Euler was invited to Berlin by the Prussian king Frederick II to help establish an Academy of Sciences in the city. He moved to Berlin in 1741 and became the director of mathematics at the Academy in 1744. Euler remained prolific in Berlin, writing about 380 articles during his 25-year tenure. Contributions to Mathematics Some of Eulers most notable contributions include: The Euler identity: eiÏ€ 1 0. The Euler identity is often called the most beautiful equation in mathematics. This formula shows the relation between five mathematical constants: e, i, Ï€, 1, and 0. It has wide-ranging uses in mathematics and physics, including electronics.Mathematical function notation: f(x), where f stands for â€Å"function† and the variable of the function (here, x) is enclosed within the parentheses. This notation is widely used today. Later Life and Death By 1766, Eulers relations with Frederick II had soured, and he returned to the Academy of St. Petersburg upon invitation from Empress Catherine the Great. His eyesight was in decline, and by 1771, Euler was completely blind. Despite this obstacle, however, Euler continued his work. Ultimately, he produced half of his total research while completely blind with the help of scribes and his own impressive memory and mental calculation skills. On September 18, 1783, Euler died from a brain hemorrhage in St. Petersburg. After his death, the Academy at St. Petersburg continued publishing Euler’s prolific works for about 50 years. Legacy Euler made many important discoveries in the field of mathematics. While he is perhaps best known for the Euler identity, he was a prolific and accomplished mathematician whose contributions influenced graph theory, calculus, trigonometry, geometry, algebra, physics, music theory, and astronomy.

Current Events in International Entrepreneurship Essay

Current Events in International Entrepreneurship - Essay Example What is observable is the general rise in the Total Early-stage Entrepreneurial Activity throughout the world between the year 2010 and 2011 which contradicts with the experience in previous years. While efficiency-driven economies improved by nearly 25%, innovation-driven economies followed with a 22% increase. In fact, there are various factors that can be measured in order to understand entrepreneurship in a nation. The first one among them is the percentage of working age population who own or are engaged in setting up a new business. In addition, it is helpful to understand the informal investment rate. It means the percentage of the population who has personally invested in the business run by some other one. According to the GEM 2011 Global Report, some other important measures are the percentage of ventures with new products and new services, the percentage of foreign customers, and people’s belief about the chances for setting up a new business in their country. In or der to understand the situation in the nation, it may also be useful to assess people’s attitude towards new entrepreneurs in the society. It can be understood by checking if people believe entrepreneurs get high status in the society. Another vital measure is the involvement of media. For example, people’s perception of the degree of media exposure new successful ventures get has an impact on the entrepreneurship in total. 2. Entrepreneurial Ecosystem and Its Components In fact, the entrepreneurship ecosystem consists of six domains which effectively classify the hundreds of elements the ecosystem. They are conducive culture, enabling policies and leadership, availability of appropriate finance, quality human capital, venture-friendly markets, and infrastructural supports. The mere fact is that each ecosystem is in fact unique in nature with its own features. For example, in Taiwan, the ecosystem developed in the context of a huge accrual of highly successful Taiwanes e expatriates in the US. Similarly, the Chinese ecosystem is marked by a totalitarian government and diverse regional policies. Another interesting point is that a time comes when an entrepreneurship ecosystem becomes self-sustaining in nature. To illustrate, when it is found that all the six domains are strong enough to reinforce mutually, it is possible for the government to reduce its control over the market. As Isenberg points out, the various domains of entrepreneurship ecosystem can be identified as leadership, government financial capital, early customers, networks, labor, educational institutions, infrastructure, support professions, nongovernment institutions, societal norms, and success stories. Out of these factors, the leadership helps through social legitimacy, support, and policies. Also, there can be investment support, regulatory frameworks, and tax benefits. While educational institutions help in the form of special entrepreneurship training and degrees, societal no rms help through tolerance of risk, mistakes and failure. 3. Entrepreneurial Finance across the World It is generally found that in all countries, young and new firms have les dependence on bank financing and are more inclined towards informal financing. However, it is seen that in those nations with strict rules and better credit information, the

Energy and Metabolism, Nutrition, and the Digestive System (Synopsis) Essay

Energy and Metabolism, Nutrition, and the Digestive System (Synopsis) - Essay Example These compounds are further subdivided into many classes such as Carbohydrates into monosaccharides and polysaccharides, Proteins into amino acids and lipids into triglycerides and fatty acids (Saturated and Unsaturated). All these compounds which form the basic requirements of our body and food contribute in the process of formation of ATP, the basic energy providing compound of our body. These biochemical compounds when enter our digestive system are further broken down into their very basic compound or particle which then undergoes the process of metabolism (either anabolism or catabolism) to form ATP. Our digestive system consists of oral cavity where food is chewed, esophagus for the transfer of chewed food, stomach for the breaking down and absorption of some of the food specially Vitamin B12 and proteins and intestines (small and large) for the further absorption and digestion of remaining undigested food and removal of left over undigested food through the anal canal. All the se systems form the basis of body’s energy providing system along with liver where most of the absorbed compounds are taken and there they undergo the process of metabolism to form the basic energy providing compound of the body. An abnormality in any of them e.g. hepatitis, peptic ulcers could lead to less nutrition supplied to the body ( malnutrition) and even

The Rio de Janeiro Experience Essay Example for Free

The Rio de Janeiro Experience Essay Life is full of contradictions. The aforementioned adage exemplifies the main message of the narrative that talks about the experience of Isabel Jones in Rio de Janeiro, Brazil. As mentioned by Barthes, narrative plays an important role in the lives of people and also the society as a whole because it provides the necessary story and information about the various beliefs, values, experiences, and other important parts of an individual’s life. In the same manner, the narrative about the experience of one person in Rio de Janeiro does not only expresses a part of that person’s life but rather it also talks about important issues about the country of Brazil and its relevance in to the society. Being the case, it is essential that the narrative is critically analyzed in order to see whether life is indeed full of contradictions as seen in the eyes of an individual who actually experienced and realized such kind of reality. The first part of the narrative talks about the process by which the Isabel Jones has to live her country, the United States of America and travel far into a foreign land. The moment where Isabel left the Los Angeles and eventually her country, symbolizes the process of parting not only in terms of territorial boundaries but also when it comes to the comfort zone of the person. Living her country of origin starts her journey of experiencing new things that she is not used to. In addition, the transition of living for a new country is actually a metaphor that symbolizes the departure of Isabel from her usual way of thinking about life and comfortable lifestyle in order to venture into new experiences that will substantially change her perspective about many things, especially life in general. After Isabel’s arrival in Brazil the flow of the narrative is actually divided into two distinct experiences, wherein she came face to face with both the good and bad sides of Brazil, specifically Rio de Janeiro. The first impression that she had of Rio de Janeiro is the active and happy people that always have smiles in their faces. In relation to this, she also noticed the way by which people of various colors tend to harmoniously co-exist with each other because they each know their limitation. The use of vivid description about the scene that Isabel saw puts her narrative into life, especially with her imagery that is full of color that is also used in making the narrative of Imaginary Homelands more real-life to its readers. The narrative even pointed out the exceptional sceneries of Rio de Janeiro by using irony of comparison, which is exemplified when she described the beach that is made of black and white stones. During this part of the narrative, Isabel’s perception of contradiction or differences are actually in a positive light that added more beauty to the new city that she is in. The frame of mind of Isabel is not explicitly shown in this part of narrative just like Jayne Anne Phillips’ Cheers (1979), the description of Rio de Janeiro’s shows her perspective without directly telling it. When Isabel was already on her way to the Ipanema Lodge, she was already having a preview of the actual irony of the situation in Rio de Janeiro wherein she is both fascinated and confronted by the beautiful sceneries and interesting facts that Lunzinho were describing to her, which gives importance to the history of the country just like the way Isabel Alliende wrote her narrative entitled Unrooted Childhood but she also took notice of the children sleeping in cardboard boxes. This is the first instance that Isabel is hit by the reality that Rio de Janeiro is not all color and fun because there is actually a depressing reality with it and that is poverty. Once Isabel arrived in the Ipanema Lodge she was introduced to her roommate, Christina Lopez. The narrative included the actual conversation between Isabel Jones and Christina Lopez during the first time that they meet each other. It is quite obvious in their exchange of conversation that these women already like each other because there is a certain connection among them that made them feel at ease with each other. The comfortable relationship between Isabel and Christina is brought about by the common interest that they have like teaching children and even when it come to their sense of humor, which is quite observable when they both found the reaction of Lunzinho as funny. The inclusion of conversation in the narrative gives its readers a more vivid impression of the relationship that exists between the two women. The exchange of conversation between two people is one of the most effective way to properly establish the dynamics of the relationship of the main actors who are involved in a narrative, which is also exemplified in the work Martin Amis’ wherein he used the actual conversation of him and his father in order to let the reader see and identify their actual relationship. Isabel spent her following experiences in Rio de Janeiro with the company of Christina. The first things that they did together are enjoy the luxury and amenities of the Ipanema Lodge, especially its beach. Both women were having fun in the Ipanema beach when they met young men who they thought at first will protect them but eventual became the cause of trouble. At first, Isabel and Christina thought the young man was kind enough to offer his assistance to two women by means of making sure that no guys in the beach will take advantage of them. The two women, having good-natured qualities just allow the young man to help them but the young man does not know his limitations and even threaten the NGO representative that was assigned to the two women. In this incident, Isabel saw that her previous notion that people in Rio de Janeiro know their limits, do not apply to all people because there are also those who will break the rules and get themselves hurt just like what happen to the young man. In the behavior of the young man, the concept of psychoanalysis that is given importance in the post-modern theory of narrative is highlighted. Isabel and Christina are not the only people who are puzzled and shaken by the behavior of the young man because the inclusion of this incident in the narrative also makes its readers question psychological well-being of the person as well as the possible reasons that turn him into such kind of person. The most important and life-changing part of Isabel’s travel to Rio de Janeiro is when she experienced going to the favelas or slums in Brazil. Isabel and Christina personally experience the poverty in the country wherein the young children that they have to teach are not given the opportunity to study or even play because most of them have to work at a very young age. Both women saw and feel the depression situation of the people in the favelas with their homes squatted in mountain side and the difficulty of the people to make ends meet for their everyday needs. It is in this situation that the narrative regarding Isabel’s experience in Rio de Janeiro does not only tell about her story but it also narrated the people in the favelas and the situation of Brazil. The experience of Isabel in Rio de Janeiro allowed her to see the contradictions of life that the presence of good and lavish things in life also meant the existence of untoward things like poverty. Isabel’s visit in Rio de Janeiro changed her perspective about being a teacher and also her perspective in life because there is a deeper awareness within herself and also a challenge to contribute something and make a difference as an educator.

Ancient and Modern Elements in Julie Taymors Adaptation of Shakespeare

Ancient and Modern Elements in Julie Taymor's Adaptation of Shakespeare's Titus Andronicus Roman coliseum . . . Formica kitchen Armored warrior . . . Armored tank Gregorian Chant . . . Hard Rock White toga . . . Metallic business suit Ancient Rome . . . Modern America At first glance, these categories appear entirely incompatible, unable to exist together. However, in Julie Taymor's adaptation of Shakespeare's Titus Andronicus, we find that they are compatible after all. With elaborate sets, stunning costumes, and a remarkable film score, Taymor blurs the boundaries that divide them and creates a world that accommodates both ancient Rome and modern America. The film soundtrack was an important element in creating the juxtaposed world that Taymor desired. Taymor selected Elliot Goldenfall, a veteran composer for the stage and screen whom she had known for twenty years, to head the scoring. Their long association served them well in this endeavor - the final film score was both stunning and effective in combining ancient and modern musical elements. Goldenfall manipulated four main musical styles to score the film (symphonic, jazz, hard rock, and aria), and each style represented particular emotions. The opening scene in the coliseum is a particularly potent display of Taymor and Goldenfall's artistic creativity. Warriors covered in gray armor, stoic faces smeared with a bluish-gray paste, march resolutely into the coliseum. As they move into formation, Goldenfall uses the powerful sounds of symphonic music to instill a feeling of triumph. Horns blare victoriously. Footsteps are marched in a steady andante, matched with heavy drums. A strong male chorus joins the music, the singing reminiscent of modal G... ...us, and various dignitaries enter the dining room, Goldenfall inserts a muted Italian aria, like one heard in a fine Italian restaurant. Considering the nature of the scene and the audience's knowledge of what is to be served, the aria serves to increase audience disgust. And as the beautiful music wafts through the background of the scene and Tamora eats the flesh of her own sons, the revulsion is intensified. It is almost a relief when the scene erupts into violence. It is not an easy task to fuse modern society with that of ancient Rome. However, under Taymor's direction the sets, costumes, and film score accomplish just that. In particular, by combining modern and archaic music styles, Goldenfall successfully augments the effects Taymor strives for. The result is a high-powered film that takes Shakespeare's classic to levels it has not previously been taken.

One Flew over the Cuckoo’s Nest Essay

The six psychological approaches are biological, learning or behavioral, cognitive, sociocultural, psychodynamic, and humanistic. Each approach is unique in its own way and used by psychiatrists to diagnose the problem. A biological approach is applied when the there is a known medical condition. The medical condition normally connects to mental health, and the solution comes from therapy. This particular approach looks at the whole body. The learning or behavioral approach is all about analyzing the person’s the behavior and modifying their behavior biased on their response to the environment. This approach works from positive and negatives items in their environment, and is sometimes cured by brings these elements in and out of their life to fix the problem. The events in the environment can be rewards or punishments that will influence the patients behavior. The cognitive perspective is about understand a patients thinking and understanding. How we process, store, and retrieve information influences our behavior. It is said that all problems are located in the brain, and using this perspective you can find a medical issue that is affecting how the brain is working. The sociocultural approach is when the mental health has something to do with the environment that deals with growth. The culture in which the patient is a large factor. In a psychodynamic approach an individual’s problem is inside the unconscious mind. This can be from a dramatic event that happened earlier in their life. Sometimes the cure can be from the patient themselves accepting the fact, or acknowledging that they have a problem. The final approach is a humanistic approach. This is about individual or self directed choices that influence behavior. This approach deals with the physical health of a patient to eventually cure their mental health. There is a well known philosophy that a healthy mind equals a healthy body. In this approach, a psychologist will control the patients diet and exercise to regain their mental health. The hospital used many methods on the mentally ill patients. They had group counseling scheduled every day where Mrs. Ratchet interrogated the patients and made them feel uncomfortable. The hospital also had electric shock therapy and lobotomy as other treatment methods. Also, the hospital gave the patients medicine, this is a biological approach, even though it was given to these people unwillingly. Mrs. Ratchet also allowed McMurphy to receive a vote in order to watch the ball game and she bended the rules or was too strict in order to win her position. This is a behavioral approach because McMurphy watched the baseball probably in his normal environment at home. She teased him with the thought of watching the game as a reward, then took it away. McMurphy had behavioral or learning approach. He would congratulate people when they did things he thought were good and he would yell at them when he thought they did something bad. For example, when McMurphy taught Chief how to shoot a basketball, he cheered after every point he made. The other patients looked up to and really admired McMurphy, which put him in a very powerful position. He had a strong effect on the other patients and they really admired him. Chief Bromden’s recovery began when McMurphy came to the hospital and started talking to him and making him do tasks. McMurphy worked on chief to see if he was smart enough to complete simple tasks. The first step was him raising his hands above his head at the basketball court, which was the first movement he had done in his whole time being there. Before chief wouldn’t handle directions from others very well. His next step was raising his hand to vote on watching the baseball game, which McMurphy also encouraged greatly. Later, McMurphy rounded up the patients to play some basketball. McMurphy passed the ball to Chief and he shot it, which was followed by him beginning to follow orders and run up and down the court. The final step was when McMurphy gave him the gum before Electroshock Therapy and the Chief spoke fo r the first time at the clinic. After this, chief revealed his intelligence to McMurphy. Ken Kesey was always very interested, and was very talented with the subject of psychology. In 1959 he volunteer to take part in a study named Project mkultra  , this was a CIA funded project dealing with psychoactive drugs. Some of the drugs included were LSD, psilocybin, mescaline, cocaine, AMT, and DMT. This and his work at the state veterans hospital, which gave him access to LSD, inspired him to write One Flew Over the Cuckoo’s Nest. At the state veterans hospital, Kesey spent a lot of time talking to the patients. sometimes under the influence of the hallucinogenic drugs with which he had volunteered to experiment. Kesey did not believe that these patients were insane. Kesey believed that society had pushed them out because they did not fit in the the culture, and that they just wanted a place to keep all the mentally ill. I think that Kesey was trying to convey to people at mentally ill hospitals were treated in a bad manner. He tried to show people that the mentally ill were probably sheltered away from everybody just because they were different. The hospital portrayed in the film didn’t seem to help the patients out or want them to recover and go home. They seemed to have no rights. These patients adjusted to this lifestyle and didn’t want to leave, that is a problem when the assumed goal was to improve these people’s problems. The rewards from good behavior seemed nonexistent and He also wanted to show how cruel the punishments were in the hospital. â€Å"Psychedelic 60s: Ken Kesey & the Merry Pranksters. † Psychedelic 60s: Ken Kesey & the Merry Pranksters. University of Virginia / Charlottesville, Virginia, 16 Dec. 2009. Web. 19 Sept. 2012. . I really enjoyed One flew over the Cuckoo’s Nest. I thought the movie was genius. There were parts of humor, and it kept you interested and wondering so many things. I enjoyed that there were many main plots and side plots, like the hospital verses the patients, or the patients versus their own recovery. McMurphy was a very mysterious character, because he was crazy, and nobody could figure out if there was anything wrong with him. I though that putting him in that section of the hospital was a mistake, because he is so manipulative and high functioning that he abused all the hospital’s loop-holes. At the same time he was very good for the patients. I also enjoyed the character and all their different problems and personality differences. I enjoyed watching how Billy and the Chief progressed mentally throughout the film. I also love the thought of people breaking structure, and that is what McMurphy definitely succeeded in. This movie very closely related to psychology, because it directly dealt with people who were mentally ill. Also psychology was involved when McMurphy used his genius mind to go against the hospital in various ways. Thinking of these schemes uses a large amount of psychology. Even for the viewers, the movie left you deep in thought, with predicting and questioning what is going to happen next. This movie made you think deeply making this a very psychological movie.
