Electrostatic loudspeakers essays

Electrostatic loudspeakers essays The field theory applies in many principles of technology. From communications and transportation and all the way to entertainment. Today, entertainment is a big part of our lives. It includes roller-coasters, satellites, TVs, sound and much more. Sound, or more specifically speakers, have started from the plain wooden boxes, and have traveled a long way to reach today's technology. Today, speakers are built much stronger, with better designs, and higher capability. As the technology continues to emerge into entertainment, speakers improve and get even better. Today, a few year study and enhancement in technology makes it possible for speakers to reach a new era. A technology still developing has come out with electrostatic loudspeakers (ESLs) which are quite different from the current speakers. Mainly, because they do not use magnets. They use static electricity. But before we step forwards into this new era, lets understand the speakers we use today. These speakers are called electromagnetic speakers. They are built from a plastic cone (usually plastic) which is attached to a metal which is wrapped around with a wire. Around that a magnet is placed. When the music is not playing, the cone stays in place and no sound and is created. When the music is playing, it is converted into electricity and travels through the wire, hence charging it. Because, the charges constantly switch from positive to negative and vice versa, they are pushed back an d forth by the magnet. Because of the movement, sound waves are created. Electrostatic loudspeakers, take a step back from the rules of magnets, and use the most basic laws of physics. Electrostatic loudspeakers are made of three layers. They are made of a coated diaphragm, which is sandwiched by two stators. The diaphragm is one of the three key components of the speaker. It is an extremely thin film (1/10th of human hair) , whose weight is irrelevant. The diaphragm is the reason why ESL s...

PSAT Test Dates 2018

PSAT Test Dates 2018 SAT / ACT Prep Online Guides and Tips Will you or your child be taking the PSAT in 2018? Are you wondering what day the exam will be held?The PSAT is different from other standardized tests, such as the SAT and ACT, because you cannot choose which day you’d like to take the exam. When will this test date be? What if you can’t make it? This guide will answer both those questions, as well as explain the importance of PSAT scores, when you can expect to receive your scores, and how you can prepare for the exam. How Is the PSAT Administered? When you take the SAT and/or the ACT, you’ll have a choice of test centers and dates to choose from. This isn’t the case with the PSAT.With the PSAT, you’ll take the exam during the school day (unless the exam is on a Saturday) at your high school, on a date that has been predetermined by the College Board, the makers of the PSAT. The College Board offers a primary test date and an alternate test date, and each school decides which date they will administer the PSAT on.The College Board recommends using the primary test date, and the vast majority of schools will choose that date to administer the PSAT. Generally, schools will only choose the alternate test date if there are circumstances that make it impossible for them to choose the primary test date. You’ll have to take the PSAT on the date that your school offers it. What Are the Expected PSAT Dates for 2018? What will the PSAT test date be for 2018? Here are the official 2018 PSAT test dates: Primary test date: October 10, 2018 (a Wednesday) Alternate test date: October 24, 2018 (a Wednesday) Saturday test date: October 13, 2018 (a Saturday) As mentioned above, each school will choose a test date and inform its students in advance as to when that date will be. Most schools choose the primary test date, which, for 2018, will be October 10. What If You Miss Your PSAT Date? What if you can’t take the PSAT on the date your school is offering it? Are there any other options if you’re sick or absent that day? Yes! If you miss the PSAT exam date, you may still be able to retake the test. In order to do so, you must contact the National Merit Scholarship Corporation in writing by March 1st. On their website, the National Merit Scholarship Corporation states, â€Å"A student who does not take the PSAT/NMSQT because of illness, an emergency, or other extenuating circumstance, but meets all other requirements for NMSC program participation, may still be able to enter the competition. The student or a school official must write to NMSC as soon as possible after the PSAT/NMSQT administration to request information about procedures for alternate entry to the National Merit Scholarship Program. The earlier NMSC receives the written request, the greater the student's opportunities for meeting alternate entry requirements. To be considered, a request must be postmarked no later than March 1 following the PSAT/NMSQT administration that was missed. NMSC will provide alternate entry materials that require the signature of a school official.† For most people, the only reason to try and make up the PSAT would be if you’re aiming for National Merit.If you just wanted to use the PSAT as practice for the SAT, it’s much easier to take a timed practice test on your own time rather than go through the whole process of making up the PSAT. If you miss the PSAT, you may still have another chanceto take it. When Will You Receive Your PSAT Scores? After you take the PSAT, how quickly will you receive your scores?You can expect to get your PSAT scores in January, so about three months after you take the exam. Sometime in January, typically in the middle of the month, you’ll receive an email telling you that you can view your scores on your College Board account. Your school counselor will receive access to the scores the day before. By the end of the month, your school should also issue paper score reports to all students who took the PSAT. Your score report will include your total score (from 320-1520), two section scores in Evidence Based Reading and Writing as well as Math (from160-760), three test scores in Reading, Writing and Language, and Math (from 8-38), as well as several other subscores so you can see how well you did on specific areas of the test.Your score report will also include your Selection Index Score (ranging from 48 to 228), which will give you an idea if you quality for National Merit. PSAT scores are important for two main reasons. First, they give you an idea of how well you’d perform on the actual SAT and where your strengths and weaknesses are. Second, juniors who take the PSAT have the chance to qualify for National Merit awards and scholarships if they score very well on the test. Want to improve your PSAT score by 150 points?

Raymond Carver Essay Example | Topics and Well Written Essays - 1500 words

Raymond Carver - Essay Example When the family moved to California, Carver became interested in writing and took a course from John Gardner, which had a profound effect on him. He continued his studies at Chico State University, Humboldt State College, and the University of Iowa. He earned a BA in 1963. He became a textbook editor at Science Research Associates, Palo Alto, but was fired in 1970. He went on to teach at universities throughout the United States and from 1980-1983 was a professor of English at Syracuse University. While Carver was at Humboldt, he wrote his first story, "Pastoral," as well as his first poem, "The Brass Ring." Although his biography states he started his writing career as a poet, he confessed he was never a "born" poet (Liukkonen) and although he eventually had his poetry published, it never received the acclaim of his short stories. His story "Will You Please Be Quiet, Please" was written in 1967 and with the editing expertise of Gordon Lish, he published a collection of stories of the same name set in Eureka, California in 1976 (Boddy). During the ensuing years, alcohol was a problem for him and drinking became a full-time pursuit. In fact, alcohol became a subject in several of his stories. On June 2, 1977, Carver stopped drinking and became active in Alcoholics Anonymous. He begin seeing poet Tess Gallagher and divorced his wife MaryAnn in 1982. He lived with Gallagher and married her two months before he died from lung cancer in 1988 (Liukkonen). Carver has said that everything we write is, in some way, autobiographical. In a New York Times article he said he considered the short story a vehicle for transforming the commonplace and said, "it is possible to write a line of seemingly innocuous dialogue and have it send a chill along the reader's spine" (Carver par. 9). His writing style is muted and anticlimactic but creates a tense atmosphere. His life is basically divided into two sections, one before he gave up drinking and met Tess and one after. "Cathedral," a short story contained in a collection by the same name, gives him the chance to write in retrospect, utilizing his life experiences in the first section of his life as part of his writing within the second part of his life. His father's alcoholism possibly led to Carver's addiction to alcohol since an addictive personality can be and often is passed down. "Cathedral" was published in 1983, after Carver had joined AA, but the characters in the story spend a great dea l of time in intervals of drinking and smoking marijuana. There are three characters in the story-the narrator, his wife, and a blind man. The narrator, who would appear to be based on Carver himself, distances himself from the story by being an observer rather than a participant-at least at first. As the story progresses, he unobtrusively fixes himself drinks, and although it is never evident or brought out, the excess drinking throughout the story labels him as an alcoholic, albeit a recovering alcoholic.. He refers to his wife's friend as "this blind man," and it is clear he is dismissing any personal interest in the man's forthcoming visit. "I wasn't enthusiastic about his visit. He was no one I knew" (Carver "Cathedral" 1). Even so, he offers the reader background on the

Career review and action plan - Essay Example This self-awareness forms part of what Goleman calls ``emotional intelligence which is an important emotional competency and cornerstone in one’s personal success. (McCarthy and Garavan 1999). Concretely, emotional intelligence is defined as a â€Å"form of social intelligence that involves the ability to monitor one’s own and other’s feelings and emotions, to discriminate among them, and to use this information to guide one’s thinking and action† (Salovey & Mayer, 1990 cited in Cherniss, 2000 pg. 4). Emotional intelligence is not only beneficial to me in terms of enhancing my professional success through social competency but could also improve my relationship to others. This improved relationship with others has several beneficial implication. On a personal level, it will improve my personal relationship with others making my personal life richer and fuller.

It is because getting things done particularly on large scale involves working with other people from varying background (social, education, culture, etch), other teams and the ability to work with others requires emotional and social competency to effectively relate to others of which self-awareness is a requisite. Psychometric and personality test are useful tools that help determine ones personality, character and motivation that would serve as a guide or signpost in charting one’s action plan. As the legendary strategist Sun Tzu said that knowing oneself is half in winning a battle. This

Arguments of Cause and Effect Assignment Example | Topics and Well Written Essays - 500 words

Arguments of Cause and Effect - Assignment Example The above scenario offers an example of cause-effect relationship in which one act directly yields effects. The woman let go the hand of the son who was adventurous and took the opportunity to walk around alone with the effect of becoming a missing person case. In this context, it can be observed that cause-effect relationship is subject to the concepts of necessary and sufficiency (Trapp,et al,pg.87). Cause: A man who was almost being attacked by robbers escaped death narrowly on the hand of the mob that mistaken him to be the criminals. The robbers attacked the man in a corridor sandwiched between two walls. He raised alarm through shouting and calling for help. The members of the public took position at the end of the corridor awaiting any person who would appear running and lynch under the possibility of being the robbers. Unfortunately, the robbers jumped over the walls and vanished into the nearby woods. The shaken victim took to his heals and just as he popped out of the corridor, the mob descended on him with kicks and blows. It took the intervention of the police to disperse the crowd before he could give a convincing explanation that shocked the public. He was the victim and the robbers wittingly escaped over the walls. The likelihood of walking through the corridor and being attacked by the robbers are correlated but that did not cause the members of public to attack hi m. Trapp, Robert, and William J. Driscoll.

The Disappearing Ozone Layer Essay Example for Free

The Disappearing Ozone Layer Essay The Ozone Layer extends from twelve to thirty miles above the surface of the earth. Oxygen in the presence of sunlight forms Ozone. It acts as a barrier to the carcinogenic ultraviolet radiation that is emitted by the Sun (Ozone Layer, 2005). The Ozone molecule consists of three Oxygen atoms. It is unsafe to inhale and most of it is to be found in the stratosphere. It absorbs a particular band of ultraviolet radiation, from the Sun, that has a wavelength between of 280 to 320 nanometers. This ultraviolet radiation known as UV – B causes great harm to the DNA of living organisms (Ozone Depletion , 2006). The Ozone layer is destroyed by the Chlorofluorocarbons or CFCs, which were previously used in refrigerants and cleaning agents, and other Ozone Depleting Substances or ODS that, are used in fire extinguishers. The chlorine in the CFCs is released when the Ultraviolet light splits them and these halogen atoms destroy the Ozone by combining with the third Oxygen atom in the Ozone molecule. Subsequently, this molecule combines with a free Oxygen atom to release the halogen atom which again breaks up another Ozone molecule. One halogen atom destroys around a hundred thousand Ozone molecules (Fahey, 2003). The main halogens that cause the depletion of the Ozone Layer are Chlorine and Bromine. Due to exposure to sunlight the halogen source gases are converted into halogen gases that are highly reactive. For instance, chlorine based gases get transformed to ClO or chlorine monoxide and bromine based compounds change to BrO or bromine oxide. In addition, chlorine and bromine atoms are also formed which are highly reactive and cause untold damage to the Ozone Layer (Fahey, 2003). The depletion of the Ozone Layer is not uniform and there is considerable variation with latitude. Due to the extremely high Ozone losses in the Antarctic region the loss is at a global maximum there. The next highest losses transpire in the Northern Hemisphere. The air that has been depleted of Ozone spreads from the Polar Regions. The depletion in the tropical regions is the least because of the fact that reactive halogen gases are present in very small quantities (Fahey, 2003). Further, a seasonal variation has also been noticed in this Ozone Layer depletion process. In the Southern Hemisphere, there is not much of a variation in the process and the amount of depletion is around six percent. However, in the Northern Hemisphere, the variation between winter and summer is from four percent to two percent respectively (Fahey, 2003). Atmospheric Ozone is of three forms the good form, the bad form and the natural form. Good Ozone is the Stratospheric Ozone that protects humans, animals and plants from UV – B radiation. Bad Ozone occurs near the surface of the Earth due to chemical reactions and human activities that produce polluting gases. Industrial activity and the consumption of fossil based fuels cause an increase in bad Ozone (Fahey, 2003). The natural form of Ozone is one of the constituents of a clean atmosphere and if there had been no human activities on the surface of the Earth then Ozone would have been observed at the surface of the Earth and in the troposphere and stratosphere. Ozone extracts other naturally and manmade gases in the atmosphere (Fahey, 2003). Realizing the gravity of the situation, twenty countries became signatories at Vienna to a treaty agreement in 1985. This treaty was named the Convention for the Protection of the Ozone Layer and it was decided to protect the Ozone Layer from the depredations of human activities. Subsequently, the Montreal Protocol on Substances that Deplete the Ozone Layer was ratified in 1989 (Fahey, 2003). This Protocol implemented controls on the developed and developing countries in respect of the manufacture and utilization of chemicals that were instrumental in causing a depletion of the Ozone Layer. These measures were further strengthened by the 1990 London Amendments to the Protocol, which made it mandatory to reduce the production and consumption of such substances. The directives of the Montreal Protocol have proved to be successful to some extent. With increasing depletion of the Ozone Layer the Ultra Violet Radiation reaching the surface of the Earth increases (Fahey, 2003). UV – B radiation causes non – melanoma skin cancer. In the United States of America skin cancer cases are increasing tremendously. The situation is very serious with twenty percent of the residents developing skin cancer. The fatalities from this disease alone are one per hour in the US (Health Effects of Overexposure to the Sun, 2006). Moreover, UVB causes actinic keratoses and premature aging of the skin. Keratoses or lesions occur on the face, upper limbs and neck of individuals. These can lead to squamous cell carcinoma. In addition, UVB brings about a loss in the transparency in the eye lens or what is commonly termed as cataract. Millions of Americans are afflicted by this malaise every year and the expenditure this incurs is of the order of several billion dollars. Further, such radiation causes the degeneration of the macula or that part of the retina where visual perception is at its best. Another grave problem created by such radiation is the impairment of the immune system of the human body (Health Effects of Overexposure to the Sun, 2006). The government of the state of Mississippi being seized with this extremely serious problem posed by UVB radiation has implemented several measures. In this state a large number of air-conditioning and refrigerating units are employed. Some of these refrigerants are Freon 12, Freon 22 and R – 12. By 1995, the production of R – 12 was completely stopped and new substances like HFC – 134A are being used in its place. The government has prohibited the release of Freon into the atmosphere and Freon is being sold only to certified technicians. All air – conditioning and refrigerant equipment has to be thoroughly inspected in order to ensure that the leakage of Freon into the atmosphere is minimized (Moore Kimbrough, 2007). A team of scientists, led by Dr. Yang, of the Georgia Institute of Technology, analyzed data collected over a quarter century. This data had been collected by NASA and NOAA or the National Oceanic and Atmospheric Administration. Since, 1979 there had been a drastic depletion of the Ozone Layer. However, in 1997 a reversal in this trend was observed. This was in no small measure due to the proper implementation of the Montreal Protocol. This had prompted Yang and his team to conclude, after extrapolating from the available data, that the Ozone Layer would be restored to its 1980 status by the year 2050 (NASA, NOAA Data Indicate Ozone Layer is Recovering, 2006). However, till such time, it is imperative for people to take abundant precautions. Some of these are the avoidance of the midday sun in summer, protecting the eyes from direct sunlight by wearing sunglasses that filter out Ultra Violet Radiation and eschewing the use of aerosols and CFCs. In addition, liberal use of sunscreen with a sun protection factor or SPF of 15 or more, protective clothing and wide – brimmed hats have to be utilized, especially in the case of children. This is due to the fact that the skin of children is much more sensitive than that of adults. Moreover, every effort should be made to avoid direct sunlight, especially between 10 am to 4 pm.

Critically assess the main arguments in Outsiders

Critically assess the main arguments in Outsiders Arguing that social deviance is a more common phenomenon than perceived and that conventional wisdom that social deviants are pathological is incorrect Howard S. Becker, born April 18th 1928, is a well known renowned American Sociologist. Of all his many writings, Outsiders, which was written in 1963, is one of his most imperative and prominent works, regarded as critical classical study within the discipline of sociology and deviance. It can be said that it is one of Beckers most famous pieces of work which offered one of the first and clearest explanations for the labelling theory. Outsiders continues to be a seminal text on the Interactionists approach to deviance in society today. He states that the outsider the deviant from group rules has been the subject of much speculation, theorizing, and scientific study (Becker 1997: 3). Howard Becker elaborates the study of deviance specifically from a social perspective, and considers the processes by which people or different types of acts come to be labelled as deviant. His ideas and arguments are based upon his notion that deviance is not a quality of a bad person but it is the res ult of someone characterizing and labelling someones activity as bad. This essay asks one to critically assess the main arguments Becker puts forward in Outsiders. Becker sets the foundations for his ideas on labelling theory in his book and furthers the notions of other Sociologists such as Edwin Lemert. Lemert has been commonly credited with being the founder and one of the firsts to discuss what has been called the Societal Reaction theory. In Lemerts book Social Pathology written in 1951, Lemert summarized an approach which has been regarded and considered to be an original version of the labelling theory. In his book he focuses on the social construction of deviance and explained deviance to be the product of societys reaction to an act and the affixing of a deviant label to the actor. The book explains the concepts of primary and secondary deviance and according to Lemert; primary deviance is the initial incidence of an act causing someone of authority to label the actor as deviant. This initial labelling of an act deemed deviant would stay prima ry for as long as the actor can rationalize the process as a function of a socially acceptable role (Lemert 1951). As well as discussing the theory of labelling, Becker appraises the process in where users of marihuana become labelled as deviants and talks about jazz music. The main objective is to attempt to critically evaluate and analyse the ideas and themes contained within the book and assess his arguments. The book was written in the 60s and as a consequence it is quite outdated, and although some of his ideas and theories are relevant in todays society, some of them can not in context. In addition he uses the term `Negros rather than African American to describe black people and he puts homosexuality into the same deviant group such as alcoholics, gamblers and people who are on drugs. In Beckers book he coins and furthers the term labelling theory. It explains that if individuals or groups are defined as deviant, there will be important and often unanticipated consequences at the level of behaviour (Abercrombie et al. 1988: 132). Chapter one explains what deviance is and Becker argues the limitations of existing attempts to define deviance. He explained for deviance to exist, the behaviour has to be first observed and then judged to be deviant. Becker stated that social groups create deviance by making the rules whose infraction constitutes deviance; and by applying those rules to particular people and labelling them outsiders (Becker 1997: 9). When a rule is enforced, the person who is supposed to have broken it may be seen as a special kind of person, one cannot be trusted to live by the tiles agreed on by the group. He is regarded as an outsider (Becker 1997: 3). Furthermore, Becker points out that what one may define as a deviant; another perhaps in a different society would not. In addition the person who is thus labelled an outsider may have a different view of the matter and may believe that those that have judged them not to be legitimately entitled to do so so then the rule breakers may see those tha t judged as outsiders. Becker stated that different social groups created deviance by making the rules whose infraction constituted deviance and by applying those rules to particular people and labelling them as outsiders. Becker stated that after one has been ascribed as a deviant, they then progress down the path of a deviant career as that is what they have been labelled as. This then becomes hard to get rid of. Becker claimed though that when we are studying people who are deviant we should not take their deviance for granted due to the fact we cannot assume that these people have actually committed a deviant act or broken some rule, because the process of labelling theory may not be infallible. Furthermore, an individual who has been labelled as a deviant may not have committed the act intentionally believing that it was in fact deviant. In addition, this does not necessarily mean that the individual was even a deviant in the past which is a critical examination of the book. Wh en a person is labelled as such by society, they then accept this label so because they now seem themselves as criminals they then are likely to continue on their deviant behaviour (Becker 1997).  Deviant becomes a master status, it becomes the key definition in the eyes of the wider society of who and what you are. In chapter two Becker points outs and states that he is not here to argue that only acts which are regarded as deviant by others are really deviant (Becker 1997: 19). If we look at this in relation to homosexuality, in the 60s it was deemed as a criminal offence but too those who were homosexual it was who they were. Becker explains two different models of deviance; the simultaneous and sequential models. The simultaneous claims that particular behaviours occur as a result of a number of variables arising at the same time and the sequential model contends that particular behaviours are caused by sequence of occurrences. Becker criticises the implicit theoretical assumption in standard which attempts to explain deviancy; that all factor operate simultaneously and seek to predict behaviour. Becker used juvenile delinquency as an example and explained and argued that coming from a broken home or in an environment with negative influences will not necessarily lead to juvenile delinquency but rather would be one of a series of sequential events or circumstances.  The sequential model in addition is too apparent in the following two chapters which detail and explain how one learns the techniques of how to use marihuana and this in the process assists the formation of an individual identity. this may include joining a social group in which the drug is available and learning their techniques on how to smoke. For instance, most users agree that it cannot be smoked like tobacco if one is to get high (Becker 1997: 46). In addition without the use of some such technique the drug will produce no effects and the user will be unable to get high. In relation to a musician career, which is one of the topics Becker discusses, he stated that Members of the musicians demographic go from being `normal family men to dance musicians, adapting to the needs of that sub-culture as they do so. For example, a musician may feel pressurized and forced into playing commercial music to meet perceived demand, even if that is not the type of music they wanted to play or produce. Musicians in general continuously adapt their music to the needs of their sub-culture, even if this means compromising the quality of their music. As a result they may have been seen to be selling out, loosing their integrity and in addition they would have lost the respect from their musical counterparts.  In todays society this may be apparent in hip hop, with many people complaining that the integrity of the genre has gone with record labels interested on what sells more, rather than good music. In relation to deviance, Becker linked it and explained the processes through which dance musicians find work as deviant. Even though their culture may be different to that of an ordinary job, what they do is no different to what occurs in the music industry today. A popular quote used in show business is its not what you know, its who you know and it is just as imperative and important today as it was back in the 1960s. Nevertheless there is a contradiction when Becker talks about losing the respect of other dance musicians. It leads to the question though that how can respect be lost if all dance musicians act in the same way and manner. Thus can it be seemed deviant. The final chapter looks at problems and sympathies within the study of deviance, where Becker describes a lack of substance in the theories that exist, believing them to be faulty or inadequate. He believes that not enough is known about deviant groups such as homosexuals, and gaps exist not just with homosexuals but with other deviant groups. He also describes how access to information and to the groups that are the focus for study is restricted, because those classed as outsiders in turn reciprocate that label to the rest of society; this forms part of an element of protection on the deviants part. Questions are posed, such as `how do researchers find doctors who are drug-addicts themselves, or even homosexuals of certain kinds? Becker even asks what stand-point the researcher will take, due to the many levels of individual characteristics in any social group; essentially, how will a researcher remove any other factors that may influence his study beyond that which he intends to ma nipulate.   The work analysing how deviance is socially constructed is revelatory. This has pure presence. Becker shows how deviance is created through the appliance of rules by people who define deviance and then search for the miscreants. It is form of institutional violence enacted on the powerless outer groups to create an inner sense of camaraderie; the socially included.   Becker examines some of the criticisms and feels that labelling theory was created as a way of looking at a general area of human activity (1963). Moreover he suggests that it was created as a way of looking at a general area of human activity (1963).   However, it is not a theory, with all the achievements and obligations that go with the title, nor is it focussed exclusively on the act of labelling as some have thought. Moreover, Becker does mention some of the criticisms given to labelling theory. For example, he states how interactionist theories have been accused of giving aid and comfort to the enemy, be the enemy those who would upset the stability of the existing order of the Establishment. In essence, we have already mentioned the suggestion of Erikson that deviance is a necessary part of society, showing the difference between right and wrong, and encouraging the majority of society to toe the line at the expense of the deviant minority. A further criticism mentioned by Becker is that given by many conservative critics (although other non-conservative critics have also noted this) that is, that interactionist theories of deviance openly or covertly attack conventional morality. Becker acknowledges this, suggesting that int entionally or otherwise, they are corrosive of conventional modes of thought and established institutions. Becker (1967) goes as far as to say that the labelling theorist must side with the deviator, as it is up to the sociologists to remedy unfair situations. However, not all theorists would see the work of Becker and the other labelling theorists as quite so radical. As a matter of fact, many sociologists view labelling theory as an untestable and untrue theory. Furthermore, Becker (1963) acknowledges that his labelling theory is a theoretical approach, not a true theory. As well, Becker suggests that sociologists should attempt establishing empirical tests for his approach. As well, further criticism is given due to the fact that, following behaviour patterns is the mere result of the behaviour patterns being ascribed to it. Secondly, he suggests that while considering the more usual, everyday types of deviance, such as homosexuality, prostitution, and juvenile delinquency, the l abelling theorists have totally ignored a more dangerous and malevolent type of deviance, what Liazos himself terms covert institutional violence. He suggests that this type of violence leads to such things as poverty and exploitation, the war in Vietnam, unjust tax laws, racism, sexism, and so on (1972). However, it is questionable whether labelling theorists should even attempt to discuss forms of deviance such as this in the same way as more commonplace individual crimes, or whether the two should be kept totally separate, being so different in subject matter. Liazos also criticises the labelling theorists as they do not consider the extent of the importance of power in their substantive analysis, although all stress its importance. He says that the really powerful, the upper classes and the power elite, those that could be referred to as the top dogs, are not considered in any great detail by the labelling theorists. A further criticism of the labelling theory is that of Jack Gi bb (1966). He questions the success of the labelling theorists in terms of how they interpret the defining of behaviour as deviant, as well as, how much study is actually done in this area. In addition, Becker (1963) goes out of his way to explain the underlying problems of labelling theory. First of all, he suggests that there are not enough studies of deviant behaviour. He further implies that there are not enough studies of enough kinds of deviant behaviour. Finally, he insists that another deficiency of the labelling theory is that they dont have enough studies in which the persons doing the research achieve close contact with those that they study, in order for them to become aware of the complex and manifold character of the deviant activity. Becker (1963) also speaks of the difficulty with secrecy. As a matter of fact, in many cases the deviant individual performs deviant acts in secrecy and does not wish this behaviour to be known universally. For example, in the results fou nd by Humphreys in his study of the `Tearoom Trade`, many of the individuals partaking in homosexual behaviour were married with children. When asked later in questionnaires about their views on homosexuality, very few admitted to visiting the tearooms. In its entirety, the labelling theory has been imperative within the discipline of Sociology. What is more, after extensive critical analysis it appears to be evident that the theory has proven to be very significant in establishing a relative body of empirical research evidence on the study of crime and deviance. After an individual has been labelled a deviant they then lead a life of crime and become deviants which is the main focus Becker stressed. Nevertheless, Becker also pointed out that when studying deviant people one should not take their deviance for granted, as one cannot presuppose they had actually committed a deviant or criminal act for the reason that the process of labelling theory may not be foolproof and reliable. In other words, to be labelled deviant does not necessarily mean that the individual is, or has been deviant in the past.   Some sociologists dispute the labelling theory and insist it is not really a theory. Becker stressed the need for more empirical research on his study of it as he concluded Outsiders and many sociologists today have furthered his ideas and explanations. Nevertheless, the labelling theory will forever remain useful as long as deviant behaviour exists in society. Critically, Becker focuses on the way society reacts to people with criminal labels. He proposes that this label becomes a persons master status, meaning that this is a constant label, affecting and over-riding how others will view them. The status people use to identify and classify a person will always be that of a criminal and no matter what other social status the individual has, they will always be deemed deviant. He declared that one may be someone high in class, perhaps a sibling, parent or spouse nevertheless the first and major status that everyone would focus on was the criminal and deviant label (Becker 1963).
