Political Crisis Essays - Caricature, Cartoon, Editorial Cartoon

Political Crisis American political cartoons often follow the general displeasure of the government by the American people. They run the gamut from economics to foreign policy to the overwhelming popular topic of bureaucracy. As an avid reader of political cartoons on a daily basis I enjoy the humor and cynicism found within these forms of speech. Not only can they poke fun at politicians for their behavior, but, they often raise a strong sense of values and morals in the person that reads them. Whether a person agrees or disagrees with the way a certain topic is portrayed in the cartoon it accomplishes the artists goal of making their reader stop and ponder for a moment about the topic being covered and how it relates to them. From topics currently facing the United Nations, our federal government or current news events, the cartoonists use a medium that was once reserved for innocent humor and changes it so that it draws the readers attention (since it is a cartoon and people seem to enjoy reading the funnies), and makes a statement, whether direct or indirect, that often makes people speak about or try and change the topics outcome. Since the beginning of America political cartoons have often portrayed government officials as inept and sometimes just plain stupid. Politicians are very easy targets for the press and so become the subject of many daily papers editorial page cartoon. Although sometimes the cartoonist draws on current events and pay tribute to people who are often thought of with reverence. Take for example Charles Schultz, on the day following his death most cartoons as well as political cartoons payed homage to a person who is considered the greatest cartoonist of all time. Other cartoon strips showed their characters attending his funeral or missing him in some other way. While the most poignant political cartoon I remember about his death was by a cartoonist Mike Thompson of the Detroit free press. It showed Charlie Brown walking through the gates of heaven with an older man walking beside him and saying to him, ? Now, a few pointers about kicking a football?. The person walking with Charlie Brown was Tom Landry. Political cartoons stay on the pulse of current affairs and in doing so tries to draw the attention of their audience to the topic and nudges them to take some kind of action. So if you want to know about how a segment of America feels, turn to their editorials and read the political cartoon. Political Issues

Free Essays on Acquisition Theories

Second Language Acquisition Theories It has been repeatedly shown in many theories that the way in which people learn secondary and tertiary languages are similar to the way people lean their primary language. Chomsky looked at syntax within languages and helped to provide a natural resource in terms of structuring research techniques and line of questioning. In studies concerning children it was found that the social environment affects language acquisition. It s also found that there is also a significant connection between language and culture. Behaviorists focus on the audiolingual method in which children first listen and speak prior to learning to read and write (drill and practice). Innatists believe in creative constructive theory in which children acquiring the second language construct their rules for the second language similar to that of their primary language. Krashen as five hypotheses concerning acquisition of a second language; these include: 1.The acquisition hypothesis which states that there is a difference between acquiring and learning a second language. 2.The monitor hypothesis, which states that when a person formally learns a language, they develop and internal grammar check. 3.The natural order hypothesis which is the belief that there is a natural process when learning a new language. 4.The input hypothesis which states when one is acquiring a language, they must understand the language, its context and be aware that there are things that they do not know yet. 5.The affective filter hypothesis states that social-emotional variables such as student motivation, minimal anxiety, self confidence and self esteem can benefit the process of acquiring a second language....

Profile of Pierre de Coubertin, Modern Olympics Founder

Profile of Pierre de Coubertin, Modern Olympics Founder Pierre de Coubertin (January 1, 1863–September 2, 1937) was the founder of the modern Olympics. His campaign to promote athletic activities began as a lonely crusade, but it slowly gained support and he was able to organize the first modern Olympics in Athens in 1896. He was a founding member of the International Olympic Committee  and served as its president from 1896 to 1925. Fast Facts: Pierre de Courbertin Known For: Founding of the modern Olympics in 1896Also Known As: Pierre de Frà ©dy, Baron de CoubertinBorn: January 1, 1863 in Paris, FranceParents: Baron Charles Louis de Frà ©dy, Baron de Coubertin and Marie–Marcelle Gigault de CrisenoyDied: September 2, 1937 in Geneva, SwitzerlandEducation: Externat de la rue de ViennePublished Works:  Olympism: Selected Writings, Università ©s Transatlantiques, Ode to Sport (a poem)Awards and Honors:  Gold medal for Literature, 1912 Olympics, nominated for Nobel Peace Prize, 1935Spouse: Marie RothanChildren: Jacques, Renà ©eNotable Quote: â€Å"When I restored the Olympiads, I did not look to what was nearby; I looked to the far-off future. I wanted to give the world, in an enduring way, an ancient institution whose guiding principle was becoming necessary for its health.† Early Life Born on January 1, 1863, in Paris, Pierre Fredy, Baron de  Coubertin was 8 years old when he witnessed the defeat of his homeland in the Franco-Prussian War. He came to believe that his nation’s lack of physical education for the masses contributed to the defeat at the hands of Prussians led by Otto von Bismarck. In his youth, Coubertin was also fond of reading British novels for boys that stressed the importance of physical strength. The idea formed in Coubertin’s mind early on that the French educational system was too intellectual. What was  desperately needed in France, Coubertin believed, was a strong component of physical education. Historical Context for His Lifework Athletics were becoming increasingly popular through the 1800s, after a long prior period when Coubertins society was essentially indifferent to sports- or even considered sports to be a frivolous diversion. Scientists in the 19th century began touting athletics as a way of improving health. Organized athletic endeavors, such as baseball leagues in the United States, were celebrated. In France, the upper classes indulged in sports, and young Pierre de Coubertin participated in rowing, boxing, ​and fencing. Coubertin became fixated on physical education in the 1880s as he became convinced that athletic prowess could save his nation from military humiliation. Travels and Study of Athletics In the 1880s and early 1890s, Coubertin made several trips to America and a dozen trips to England to study the administration of athletics. The French government was impressed with his work and commissioned him to hold athletic congresses, which featured events such as horseback riding, fencing, and track and field. A small item in the New York Times in December 1889 mentioned Coubertin visiting the campus of Yale University: His object in coming to this country is to make himself thoroughly acquainted with the management of athletics at American colleges and thereby to devise some means of interesting the students at the French University in athletics. The Founder of the Modern Olympics The ambitious plans of Coubertin to revitalize the educational system of France never really materialized, but his travels began to inspire him with a far more ambitious plan. He began thinking about having countries compete in athletic events based on the Olympic festivals of ancient Greece. In 1892, at a jubilee of the French Union of Athletic Sports Societies, Coubertin introduced the idea of a modern Olympics. His idea was fairly vague, and it seems that even Coubertin himself did not have a clear idea of the form such games would take. Two years later, Coubertin organized a meeting that brought together 79 delegates from 12 countries to discuss how to revive the Olympic Games. The meeting established the first International Olympic Committee. The committee decided on the basic framework of having the Games every four years, with the first one to take place in Greece. The First Modern Olympics The decision to hold the first modern Olympics in Athens, at the site of the ancient Games, was symbolic. It also proved to be  problematic, as Greece was embroiled in political turmoil. However, Coubertin visited Greece and became convinced the Greek people would be happy to host the Games. Funds were raised to mount the Games, and the first modern Olympics began in Athens on April 5, 1896. The festival continued for 10 days and included events such as foot races, lawn tennis, swimming, diving, fencing, bicycle races, rowing, and a yacht race. A dispatch in The New York Times on April 16, 1896, described the closing ceremonies the previous day under the headline, Americans Won Most Crowns. The King [of Greece] handed to each winner of a first prize a wreath fashioned of wild olive plucked from the trees at Olympia, and laurel wreaths were given to the winners of second prizes. All of the prize winners then received diplomas and medals... .[T]he total number of athletes who received crowns was forty-four, of whom eleven were Americans, ten Greeks, seven Germans, five French, three English, two Hungarians, two Australians, two Austrians, one Dane and one Swiss. Subsequent Games held in Paris and St. Louis were overshadowed by Worlds Fairs, but the Stockholm Games in 1912 returned to the ideals expressed by Coubertin. Death During World War I, Coubertins family suffered hardships and fled to Switzerland. He was involved in organizing the 1924 Olympics  but retired after that. The final years of his life were greatly troubled, and he faced severe financial hardships. He died in Geneva on September 2, 1937. Legacy Baron de Coubertin gained recognition for his work promoting the Olympics. In 1910, former President Theodore Roosevelt, visiting France after a safari in Africa, made a point of visiting Coubertin, whom he admired for his love of athletics. His influence on the institution he founded endures. The idea of the Olympics as an event filled not merely with athletics but great pageantry came from Pierre de Coubertin. So while the Games are, of course, held on a scale far more grand than anything he could have imagined, the opening ceremonies, parades, and fireworks are very much ​a  part of his legacy. Finally, it was also Coubertin who originated the idea that while the Olympics can instill national pride, the cooperation of the worlds nations may promote peace and prevent conflict.

EUROPEAN UNION EQUALITY POLICIES AND WORKPLACE LEGISLATION Essay

EUROPEAN UNION EQUALITY POLICIES AND WORKPLACE LEGISLATION - Essay Example The legislation also advocate for the provisions that ensure that the disabled people in the society are able to work comfortably. This essay shall discuss the equality policies and workplace legislations that cover gender, age, religion and belief, race, and ethnicity. The European Union has formulated policies that advocate for gender equality in many angles. They ensure and promote the existence of equity between men and women, the promote application of gender mainstreaming and facilitate exploration of transgender issues. The policies ensure that the European Union observes gender equality in all the activities at the workplace. The legislations through the Treaty of Rome came up with a principle that ensure that each member state shall give equal pay for men women for equal work (Allen QC & Crasnow, 2001). This principle advocates for equality between men and women and concentrates in the equality at the workplace than in the society. Among all the inequalities in the workplace, the European Union takes more focus to address the issue of gender inequality. The European Union has so far launched a committee that advocates for women rights in its member states. It then established a commission on equal opportunities for all gender to support th e activities carried out by the advisory that handles issues on the availability of equal opportunities between men and women. To sum all these efforts up the European Union has a Commissioner that issues an annual report on gender equality (Carver & Mottier, 1998). The European union refers to equality between men and women when dealing with issues of gender equality rather than women rights since the latter appears as one sided which shows one kind of gender is given dominance. Apart from the provision of equal pay for equal work of an equal value for all gender the European Union has a directive that ensures equal treatment for all gender in matters concerning access to training and employment. This clause also

Dependence of Man on the Environment Essay Example | Topics and Well Written Essays - 2500 words

Dependence of Man on the Environment - Essay Example As human beings it is our responsibility to take good care of our nature and our environment. Some people also argue that environment has been created for man and he can use it in any way he wants to. Both have become banners for different power bases, making the arguments itself almost irrelevant. Human beings have the ability to use their actions in a positive way which can be useful for both the environment and their own selves. The idea of working with environmental circumstances rather than trying to control the surroundings must be the motivating idea behind any changes in the relationship with mother earth. Dependence of man on environment is a two-way link; helped in essence by the input that man has manifested within the reigns of the environment itself. The clear cut methodology for having an environmental friendly atmosphere is dependent on the actions (and inactions) of man alone. The development of new and advanced technologies is based on the idea that man can control nature to some extent and thus use it for his defensive ideologies. These changes can range from weather maps to electronic meters, and natural disasters to the natural development of the human race itself. For example, one of the most common motivating factors behind technological development is the environmental aspect of isolated expanding human populations which is, of course, war. Mankind was made and has always been supported by the environment. Both the Bible and the theory of evolution agree with this fact nonetheless. According to Bible, God has created this world and produced human beings. He is the one to have sent Adam as the caretaker of the world as well as its environment. The theory of evolution says that man appeared because he occupied a niche in the environmental scheme of things. The Bible and the theory of evolution agree on other issues as well. They both have concluded t hat mankind can only survive if it cooperates with the environment that exists

The Strange Case of Dr Jekyll Essay Example for Free

The Strange Case of Dr Jekyll Essay Just as The Italian includes a stone chamber, secured by doors of iron, Dr Jekyll and Mr Hyde too contains a peculiar locked cabinet in which Poole, Dr Jekylls butler, believes his master has been murdered and that the person who has locked himself away is Hyde. The fact that these secret rooms are included in the novels, allows the reader to speculate the strange things that might be going on behind the sealed doors of the rooms. All in all, Gothic literature is extremely evident in Dr Jekyll and Mr Hyde but at the same time it is heavily influenced by Victorian psychology, which I will now be commenting on. Victorian society was heavily based on power, wealth and culture. Victorians believed they were ethical, moral people and their society was that of an ideal one; however with the amount of crimes taking place i. e. Jack the Ripper this was not the case especially since Victorians were sexist and racist. Even though Stevenson sets his story in the heart of London using such respectable professional people as lawyers, doctors and men of science, what he shows us is a city fraught with divisions. Such divisions included those between the rich and poor, men and women, country and city, science and art, and also good and evil shown to us by Dr Jekyll and Mr Hyde, who not only does he represent a form of rebellion against the arrogant domination of the upper classes and government, but also the beast in man. Stevenson greatly investigates the duality of human nature in his novel. This theme does not emerge fully up until the last chapter, when the complete story of the Jekyll-Hyde affiliation is exposed by Henry Jekylls Full Statement of the Case. Therefore, we confront the theory of a dual human nature unambiguously only after having witnessed all of the events of the novel, including Hydes crimes and his eventual eclipsing of Jekyll. Dr Jekyll describes his dual personality as the animal within me licking the chops of memory. The text not only posits the duality of human nature as its central theme, but forces us to consider the properties of this duality and to contemplate each of the novels episodes as we weigh various theories. Such a theory includes that of Freuds theory of the id, ego and superego. The id is entirely unconscious and represents the primitive self of us. It is the self indulgent and selfish side of us. The ego, however unlike the id, spans the conscious, preconscious, and unconscious. The ego is the only component of personality that can interact with the environment. Lastly, the superego is the part of personality that establishes standards of right and wrong. The superego is the ethics and morality behind our personality. In the 19th Century, it was believed that the id was represented by a troll like figure, and Hyde is described as being pale and dwarfish. As Stevenson probes the depths of human psychology and challenges our perceptions of good and evil in society, we are struck by the disturbing face of evil. Dr. Jekyll tries to repress and kill off the Mr. Hyde in himself, but that alter ego is a part of who he is. He cannot renounce or destroy that part of himself. In The Picture of Dorian Gray Dorian, represented by his ego and superego, is in conflict with his id represented by the picture painted of him as a young, handsome man. In Henry Jekylls Full Statement of the Case the story of Jekylls downfall is revealed to Mr Utterson. Jekyll suggests to us that mankind has a split personality when saying severed in me those provinces of good and ill which divide and compound mans dual nature. Stevenson provides us with the message that man has two sides to him not just Jekyll. There are many quotations to suggest this too. Such examples in this chapter include: primitive duality of man, the agonised womb of consciousness, these polar twins should be continuously struggling- this is in fact a metaphor describing our consciousness being like a womb, man is not truly one, but truly two and lastly I stood already committed to a profound duplicity of life. From what Stevenson has produced, I can conclude that Dr Jekyll and Mr Hyde cannot easily be seen as having more to do with Gothic tradition than late 19th Century psychology. We must take into account that psychology is a subject matter and Gothic is a style, however I consider the novel has been written carefully and equally in terms of Gothic tradition and late 19th century psychology as I believe the style of Gothic literature has been heavily influenced by Victorian psychology. Some might argue against Gothic tradition being the more dominant argument, simply for the reason that Stevenson has not included involvement of haunted castles and dungeons, two of the most obvious Gothic traits. As a closing statement to this essay, I can admit Dr Jekyll and Mr Hyde was published truly as a chilling shocker in 1886 and still today remains as an original classic.

Confused Values in The Necklace Essay -- Mauassant The Necklace Essays

Confused Values in The Necklace To some people, class distinction is very important. Usually we think of class distinction as being of most importance to the higher classes, those who can afford to look down on the rest of the world, but sometimes this concept is of most importance to those who occupy the lower steps of society. These are the people who are stuck where they are, but feel that their true places are at the top of the social ladder. The character of Mme. Loisel in Guy de Moupassant's story "The Necklace" is one such person. She is of the lower classes, but she holds a romantic idea of what life at the top consists of, and it is one of these ideas that eventually gets her into trouble. The story starts out by describing Mme. Loisel and the contrasts between the world she lives in and the one she dreams of. Her life consists of simple clothes, a plain household full of functional things, and simple, healthy food. She has one servant in her house, her husband holds a good, if unglamourous, job, and they are in general a middle class family. This life is...

Acute Ankle Inversion Sprain Health And Social Care Essay

Ankle is a complex articulation which is categorized as a flexible joint articulation. It is one of the of import constituent for ambulation in worlds. Ankle sprains are one of the commonest hurts in sports. It accounts for 20 % of all athleticss hurts ( Bergfeld J ; 2004 ) .In India, incidence rate of mortise joint sprain histories for 0.31 % of the population and the opportunities of re-injury is seen every bit high as 78-80 % despite the continued research in this field ( Statistics for ankle sprain ; 2003 ) . The pathomechanics for ankle inversion hurt is inversion and plantar flexure of the ankle articulation. There is loss of dorsiflexion and inversion scope of gesture which is attributed to trouble and swelling ( Denegar CR et Al ; 2002 ) , ( Collins et Al ; 2004 ) .According to Denegar C et Al ( 2002 ) the loss of dorsiflexion scope of gesture is due to limitation of posterior talar semivowel. This suggests that in an acute mortise joint inversion sprain the loss of dorsiflexion scope of gesture could be due to mechanical disfunction in talocrural articulation. The conventional intervention for acute mortise joint sprain is RICE ( remainder, ice, compaction, lift ) .The chief purpose of conventional intervention ( RICE ) is chiefly to cut down hurting and redness ( Starkey JA ; 1976 ) , ( Slatyer MA et Al ; 1997 ) . The conventional intervention ( RICE ) with early motion is found to be more effectual for cut downing hurting, swelling and bettering mobility ( Dettori et al ; 1994 ) . Because of the ineffectualness of conventional intervention for handling the positional disfunction caused due to acute ankle inversion hurt the joint becomes more susceptible to injury ( Hertel J et Al, 1999 ) . Manual Therapy focuses on decrease of hurting and rectification of the postural and motion disfunction due to ankle sprain. Harmonizing to Maitland classs of mobilisation class I and II mobilisation is used in acute status and class II mobilisation is seem effectual in cut downing hurting and bettering dorsiflexion scope of motion in acute musculoskeletal conditions. Maitland classs of mobilisation improves the ankle dorsiflexion in acute ankle inversion sprain ( Green et Al ; 2001 ) and reduces pain by transition of nervous tissue ( Vincenzino B et Al ; 1998 ) . Harmonizing to Maitland GD ( 1986 ) , inactive articulation mobilisation improves the scope of motion by soft oscillating motion of the articular surfaces that creates motion of the nomadic sections by a means other than the musculuss.According to Collins et Al ( 2004 ) , Mulligan ‘s mobilisation with motion technique is effectual in cut downing hurting and improves dorsiflexion of ankle articulation. A individual inst ance survey done by O Brien, B.Vincenzino ( 1998 ) showed that Mulligan Mobilization with motion technique on acute mortise joint sprain improved the scope of motion ( dorsiflexion and inversion ) , functional result and reduced the hurting. Harmonizing to pilot survey conducted by John-Mark Chesney, Erin Morris, Mulligan ‘s mobilisation with motion technique and tape had important consequence on temporal and spacial parametric quantities of pace. Immediate lessening in hurting and an early return to map are claimed to be consequence of Mulligan ‘s mobilisation with motion Mulligan 1995 ; Vincenzino Wright 1995 ; Hetherington 1996 ) . However, the deficiency of equal grounds in literature for the effectivity of Mulligan ‘s anterior-to-posterior talar semivowel with motion technique in acute ankle inversion sprain failed to turn out its clinical and statistical significance in research methods. The above literature besides shows deficiency of surveies done to compar e the effects of Maitland and Mulligan mobilisation technique in intervention of acute ankle inversion sprain. Hence, the purpose of the survey is to happen the immediate consequence of Mulligan ‘s anterior-to-posterior talar mobilisation with motion technique in acute ankle inversion sprain with RICE and compare the consequences with that of Maitland anterior-to-posterior talar semivowel mobilisation with RICE for intervention of acute ankle inversion sprain.REVIEW OF LITERATUREAnkle articulation is a complex articulation due to its articular, ligamentous and sinewy anatomy. The anterior talofibular ligament restricts anterior interlingual rendition and internal rotary motion of talus inside the mortice. The conjugate gesture during plantar flexure happens as internal rotary motion and anterior interlingual rendition of scree aided by deltoid ligament. The calcaneofibular ligament restricts inversion of the talocrural and subtalar articulation. The posterior talofibular ligament restricts inversion and internal rotary motion after calcaneofibular ligament and anterior talofibular ligam ent undergo hurt. Harmonizing to Konradsen and Voight ( 2002 ) an inversion torsion was produced on lading a cadaverous leg, when the unloaded pes was positioned in 30 degree inversion, full plantar flexure and 10 degree internal tibial rotary motion. The hit with 20 grade upside-down pes in swing stage follow through forced the pes into full bound of inversion, plantar flexure and internal tibial rotary motion. Harmonizing to Denegar CR et Al ( 2002 ) in normal biomechanics the instantaneous axis of rotary motion of talocrural articulation translates posteriorly during dorsiflexion, but in anterior malaligned scree or with restricted posterior talar semivowel the axis of rotary motion is shifted anteriorly taking to joint disfunction. Harmonizing to Baumhauer JF et Al ( 1995 ) old history of sprain, limited scope of gesture and decreased dorsiflexor and plantar flexor strength ratio, elevated eversion to inversion ratio have been attributed to predisposing to inversion hurt. Harmonizing to Eren OT et Al ( 2003 ) high malleolar index ( posteriorly positioned calf bone ) is attributed to predisposing factor to twist. Average malleolar index was +11.5 grade in topics with ankle sprain and +5.85 degree in normal controls. Green T in 2001 used a Modified Lidcombe Template to mensurate the hurting free dorsiflexion scope of gesture happening in talocrural articulation. The templet consisted of 2 boards joined by an adjustable flexible joint. One board served as a footplate and other was placed under the topic ‘s calf. The adjustable flexible joint served as the axis of rotary motion of templet in perpendicular plane and the board placed under the topic ‘s calf allowed for accommodation in horizontal plane. The measuring was standardized by mensurating both force applied and the angle of dorsiflexion at which the topic foremost experienced the hurting ( Matyas T, Bach T ; 1985 ) . The force applied was standardized throughout the trail by spring balance and the way of force was standardized by spirit degree attached to the spring. The device showed high intrarater and interrater dependability of which 29 % were in exact understanding and 84.5 % were within 2 grades, ICC=0.94. The conventional direction of mortise joint sprain is RICE in acute phase of hurt. The functional intervention processs with early induction of weight bearing as tolerated, early mobilisation, proprioceptive preparation, balance preparation has been advocated to supply early functional rehabilitation to topics. Harmonizing to Bahr R ( 2004 ) and Bruce Beynnon B, ( 2004 ) the direction of sprain dressed ores on inactive and dynamic stableness, deriving normal ankle scope of gesture, optimum strength of peroneal, dorsiflexors, plantar flexors, and invertor musculuss of mortise joint and retraining ankle scheme. Harmonizing to Kerkhoffs et Al ( 2002 ) functional intervention is superior to immobilisation and surgical intercession in countries of hurting on activity, quality of public presentation on return to sport/work, objectives instability on x-ray positions and patient satisfaction. Manual therapy in ankle inversion sprain Maitland ‘s Mobilization Green et Al ( 2001 ) conducted a randomized controlled test of inactive accoutrement joint mobilisation on acute ankle inversion sprain. The survey included 38 topics with acute ankle inversion sprain ( & lt ; 72hours ) and were indiscriminately assigned to command group ( RICE ) and experimental group ( anterior-to-posterior mobilisation and RICE ) .Treatment was given every 2days for maximal 2weeks.The intervention technique used in this survey was Maitland ‘s class 3 front tooth to posterior talar semivowel of scree. Consequences showed that dorsiflexion improved earlier in experimental group as compared to the control group. Elizabeth L et Al ( 2008 ) conducted a survey in which 10 topics were taken with immobilized mortise joint for at least 14 yearss and presented with at least 5 grade of dorsiflexion shortage compared to contralateral mortise joint. A crossing over design was employed and topics received Maitland ‘s class 3 mobilisation in one group and control intercession ( no intervention ) in other group. Consequences showed that joint mobilisation led to a decrease in hurting and betterments in unpainful dorsiflexion. Mulligan mobilisation with motion technique Collins et Al ( 2004 ) conducted a double-blinded randomized controlled test with a crossing over design attack. In this survey 14 topics with grade 2 mortise joint sprain were taken. The dorsiflexion in weight-bearing and thermic hurting threshold were calculated. All the topics undergo 3 intervention conditions-Mulligan ‘s mobilisation with motion technique for dorsiflexion, placebo group and control group ( no intervention ) .Results showed that the talar anterior-to-posterior semivowel improved the recovery rate in intervention with Mulligan ‘s mobilisation with motion technique. The survey conducted by Collins N was done on topics with sub ague mortise joint sprain. T O'Brien, B.Vincenzino ( 1998 ) conducted a individual instance survey to look into the effects of Mulligan ‘s with motion technique mobilisation for acute sidelong mortise joint sprain. The technique used in this survey was posterior semivowel to distal fibular while patient actively inverted the mortise joint. In the survey 2 topics with acute mortise joint sprain were used to command for natural declaration of mortise joint sprain. Capable I underwent ABAC protocol while capable II BABAC protocol where A was no intervention stage B was intervention stage and C was post intervention return to feature stage. The result steps Modified Kaikkonen test functional result, VAS for hurting and scope of dorsiflexion and inversion were measured pre and station of each intercession session. Consequences showed rapid betterment of scope of gesture ( inversion and dorsiflexion ) and immediate lessening in hurting. Therefore from the above surveies we can deduce that anterior-to-posterior talar semivowel technique in both Maitland and Mulligan mobilisation is effectual in handling ankle inversion sprain than the RICE protocol entirely. The above surveies besides infer that Maitland ‘s classs of mobilisation is significantly effectual in bettering dorsiflexion scope in acute mortise joint sprain. However, Mulligan ‘s mobilisation had shown effectual consequences in handling mortise joint sprain in subacute status. The survey done by T O'Brien, B.Vincenzino ( 1998 ) shows the effectivity of Mulligan ‘s mobilisation with motion technique in bettering dorsiflexion scope of gesture in acute mortise joint sprain but the survey design leads to restriction of generalisation of its findings. However, it does supply the cognition to carry on a random clinical trail in public-service corporation of Mulligan ‘s mobilisation with motion technique in the intervention of acute ankle in version sprain and to compare the consequences with Maitland ‘s classs of mobilisation to happen the best effectual intervention method for bettering the recovery rate in ague mortise joint inversion sprain.IDENTIFICATION OF RESEARCH PROPOSAL QUESTIONDoes Mulligan ‘s anterior-to-posterior talar semivowel is effectual in bettering dorsiflexion in topics with acute ankle inversion sprain than Maitland ‘s anterior-to-posterior talar semivowel mobilisation.ALTERNATE HYPOTHESISMulligan ‘s anterior-to-posterior talar semivowel is effectual than Maitland ‘s classs of mobilisation in bettering dorsiflexion scope of gesture in topics with acute ankle inversion sprain.NULL HYPOTHESISMulligan ‘s anterior-to-posterior talar semivowel is non effectual than Maitland ‘s classs of mobilisation in bettering dorsiflexion scope of gesture in topics with acute ankle inversion sprain.MethodologyDesign An Experimental, Comparative, Randomized Controlled Trail design. The survey will be individual blinded to avoid any possible prejudice. The topics will be allocated to 3 group of interventions-Mulligan ‘s anterior-to-posterior talar semivowel with motion technique with RICE, Maitland ‘s anterior-to-posterior talar semivowel mobilisation with RICE, and 3rd group RICE entirely.Outcome step will mensurate the grade of dorsiflexion pre and station to each session which will be measured by the assessor blinded to the allotment of topics to the groups. Subjects The survey will be conducted by enrolling 90 samples through convenience sampling by giving advertizements and notices to orthopaedic and physiotherapy section in MS Ramaiah Memorial infirmary and the infirmaries nearby its environing countries. The topics recruited will be diagnosed for acute ankle inversion sprain and referred by radiotherapist through X-Ray imagination.

Couplings Elements Essay

Couplings are mechanical elements that ‘couples’ two drive elements which enables motion to be transferred from one element to another. The drive elements are normally shafts. We tend to see lot of applications of the couplings mainly in the automobiles, for example the drive shaft which connects the engine and the rear axle in a bus or any automobile is connected by means of a universal joint. In order to transmit torque between two shafts that either tend to lie in the same line or slightly misaligned, a coupling is used. Based on the area of applications there are various types of coupling available. But they are generally categorised in the following varieties 1. Rigid Couplings 2. Flexible or Compensating Couplings 3. Clutches to are a type of Coupling – We will the dealing on them separately. RIGID COUPLINGS Rigid Couplings are mainly used in areas where the two shafts are coaxial to each other. There are many types of couplings that fall under the rigid couplings category. They are  · Rigid Sleeve or Muff Couplings- This is the basic type of coupling. This consists of a pipe whose bore is finished to the required tolerance based on the shaft size. Based on the usage of the coupling a keyway in made in the bore in order to transmit the torque by means of the key. Two threaded holes are provided in order to lock the coupling in position. The photo shows a type of the rigid sleeve or muff coupling.  · Flanged Coupling – The coupling basically consists of two flanged end pieces as shown in the figure. A spigot and recess is provided in the flanges to provide location between them. The flanges are connected firmly by means of fitted bolts which are tightened accordingly to the torque to be transmitted. FLEXIBLE OR COMPENSATING COUPLINGS Flexible couplings are normally used in areas where the coaxiallity between the connecting shafts is not always assured and in areas where there is a possibility of occurrence of shocks in the transmission is applicable. They are also called as Elastic Couplings. By construction these couplings tend to have a elastic member in between the two connecting entities. The different types of flexible couplings are 1. Flanged Pin Bush Couplings 2. Bibbly Coupling 3. Gear Tooth Coupling 4. Tyre couplings 5. Elastomeric Couplings – This consists of jaw type and S-flex couplings. 6. Oldhams Coupling 7. Universal Coupling or Hooke’s Coupling 8. Bellows Coupling Each of the above couplings are quite unique in their construction and we can deal in detail on their constructional and working aspects in separate articles. BIBBLY COUPLING: This article deals with Bibby Resilient type couplings. The article describes constructional aspects of the coupling and the selection procedures for the coupling. * Named after its Inventor Dr. James Bibby in 1917, this coupling is still one of the most sought after flexible couplings for heavy shock applications. Let us now look at the constructional features of the coupling. 1. The Coupling consists of two flanges or hubs specifically mounted on the drive and the driven shafts respectively. These hubs contain axial grooves cut on their circumference. 2. The two couplings are joined or held together by means of a specially designed grid spring. 3. The total assembly is enclosed in a casing or shell filled with grease for low speed applications or, in high speed application with high viscosity oil. Now let’s look at the working aspect of the coupling and how it tends to reduce vibration and prevents the build up of resonance in the system. a.) The specially designed spring is wound up through the grooves forming a series of resilient bridges throughout the periphery of the coupling. b.) The grooves are tapered up at the edges (see photo) in order to provide extra flexible spans to the spring at normal loads and tends to support the spring at the sides whenever overloading occurs. c.) The stiffness of the spring depends on its unsupported length of each of its flexible span. The unsupported length tends to vary with the loads producing a varying stiffness for the coupling based on the loading. d.) This action tends to produce a detuning action altering the torsional vibration frequency of the system that prevents the build-up of resonance. Some applications of Bibby Couplings are 1. Cement Mills – in grinding and crushing machinery. 2. Cranes 3. Conveyors 4. Turbines 5. Marine Auxiliaries 6. Paper Mills Bibby couplings can be used for applications with powers varying from as low as 1 h.p to about 100,000 h.p. per 100 rpm of the coupling. Correspondingly the couplings are available in varying sizes ranging from 100mm diameter to 4000mm diameter. Bibby couplings are capable of taking axial and radial misalignments to a very small extent only. It is necessary for the user to ensure that both axial and radial misalignments are kept to the minimum possible. Selection procedure for Bibby Couplings: The selection of the Bibby coupling is mainly based on the torque being transmitted by the coupling. Each coupling has a characteristic value for the torque transmitted by it to the revolutions per minute of the coupling. The rating of the coupling is given by Rating = Maximum power to be transmitted in h.p/ r.p.m of coupling In order to account for contingencies like shocks, sudden stops, stalling, etc. a factor of safety is to be considered during selection of the coupling. Rating of coupling to be Selected = Max. power of coupling* Factor/ r.p.m. of coupling The chart containing the factors to be considered is given below based on the application and driving machinery. See the selection chart below for the selection of corresponding coupling based on the power. Note: This chart is an indicative for the selection of the Bibby coupling. Kindly refer to an actual manufacturer’s catalog for selection as ratings may vary from manufacturer to manufacturer. GEAR COUPLING: This article deals with Gear Couplings. The article describes constructional aspects and selection procedures for flexible gear couplings. * Couplings are used as connecting elements between two shafts. The complexity in the type of connectivity, the power to be transmitted and the area of application tend to play a vital role in the selection of the type of the coupling. Gear Couplings belong to the category of flexible couplings that are capable of transmitting very high torques. Constructionally the gear coupling utilizes the advantages of gear engineering; practically the coupling is a complete gear assembly. Let us now look into the constructional aspects of the coupling. 1. The gear couplings consists of a forged sleeve with internal teeth cut on its inside. The forged sleeves are normally two halves possessing internal gears in both of them. In certain cases the forged sleeve tends to remain a single piece. 2. Two hubs with external teeth containing the same number of teeth as in the internal gear is present with each one being mounted on the driven and driver shaft respectively. The tooth profile of the external teeth is normally crowned in order to take up more loads. 3. The entire assembly in normally enclosed and is provided with gaskets at the joints and O-rings at vantage points in order to prevent the leakage of the lubricant filled inside the coupling, 4. Lubrication plugs are provided at vantage points in order to lubricate the couplings during predetermined intervals of time. Tooth forms in the Coupling: Three types of external teeth are used in gear couplings. The only difference is the manufacturing methodology of the same. a.) Straight Teeth: The external teeth in the hub are straight. During the condition of misalignment in the coupling the contact pattern between the internal gear and the external gear tends to be line type of contact as shown in the figure. b.) Crowning with constant radius: The external teeth are barrel shaped with a constant radius in order to increase the area of contact and move the area of contact to a near middle portion of the teeth. c.) Crowning with variable radius: The external teeth are barrel shaped with a variable radius instead of constant radius. This increases the area of the contact significantly compared to that of the constant radius crowning. The maximum degree of misalignment permissible in gear couplings is from 0.5 Degrees to 1.5 Degrees. This varies with the size of the coupling being used. Selection procedure for gear coupling: The gear couplings are selected based on the torque ratings. 1. 1. The torque transmitted by the coupling is to be determined. 2. 2. Based on the application the appropriate service factor needs to be determined. A reference chart on the service factors is shown below. 3. 3. The equivalent torque is to be determined by multiplying the service factor with the torque transmitted. 4. 4. Select the coupling based on the equivalent torque value calculated. A reference selection chart is given below for example. JAW TYPE ELASTOMERIC COUPLING: This article deals with Jaw type Elastomeric coupling. The article describes the constructional aspects of the coupling and selection procedures. * Couplings are indispensable mechanical power transmission elements used for connecting shafts. Flexible couplings in particular are used in areas where misalignment needs to be accommodated (the flexibility is highly restricted based on the type of Elastomeric material used) and also to take up shock loads at the driven end, thus protecting the driving element like a motor or such. Jaw Type Couplings tend to have a flexible member or Elastomeric member between the two metal components. The flexible member is also called the â€Å"Spider.† The Spider material can be made from different types of rubber or plastic possessing varying degrees of hardness in order to suit the load carrying capacity of the system torsional characteristics. The constructional features of the Jaw type coupling are shown below. The dimensional drawing as wel l as the nomenclature of the coupling is also enclosed. Here as some of the key aspects on the constructional features of the Jaw type coupling. These points are to be considered for the proper selection of a coupling. – The metal hub is constructed of sintered iron, cast iron, or aluminium or stainless steel. The type of metal hub is mainly based on the area of operation of the coupling and its inertia aspects. – The spider is normally made up of a nonmetallic element like rubber, urethane, hytrel because of their Elastomeric properties and in very rare cases bronze is used. BEAM COUPLING: A beam coupling A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other. This design utilizes a single piece of material and becomes flexible by removal of material along a spiral path resulting in a curved flexible beam of helical shape. Since it is made from a single piece of material, the Beam Style coupling does not exhibit the backlash found in some multi-piece couplings. Another advantage of being an all machined coupling is the possibility to incorporate features into the final product while still keep the single piece integrity. Changes to the lead of the helical beam provide changes to misalignment capabilities as well as other performance characteristics such as torque capacity and torsional stiffness. It is even possible to have multiple starts within the same helix. The material used to manufacture the beam coupling also affects its performance and suitability for specific applications such as food, medical and aerospace. Materials are typically aluminum alloy and stainless steel, but they can also be made in acetal, maraging steel and titanium. The most common applications are attaching encoders to shafts and motion control for robotics. Oldham Animated Oldham coupler An Oldham coupling has three discs, one coupled to the input, one coupled to the output, and a middle disc that is joined to the first two by tongue and groove. The tongue and groove on one side is perpendicular to the tongue and groove on the other. The middle disc rotates around its center at the same speed as the input and output shafts. Its center traces a circular orbit, twice per rotation, around the midpoint between input and output shafts. Often springs are used to reduce backlash of the mechanism. An advantage to this type of coupling, as compared to two universal joints, is its compact size. The coupler is named for John Oldham who invented it in Ireland, in 1821, to solve a paddle placement problem in a paddle steamer design. * * it is recommended to use manufacturer’s alignment target values to set up the machine train to a defined non-zero alignment, due to the fact that later when the machine is at operation temperature the alignment condition is perfect Coupling maintenance and failure Coupling maintenance is generally a simple matter, requiring a regularly scheduled inspection of each coupling. It consists of: * Performing visual inspections, checking for signs of wear or fatigue, and cleaning couplings regularly. * Checking and changing lubricant regularly if the coupling is lubricated. This maintenance is required annually for most couplings and more frequently for couplings in adverse environments or in demanding operating conditions. * Documenting the maintenance performed on each coupling, along with the date.[2] Even with proper maintenance, however, couplings can fail. Underlying reasons for failure, other than maintenance, include: * Improper installation * Poor coupling selection * Operation beyond design capabilities.[2] The only way to improve coupling life is to understand what caused the failure and to correct it prior to installing a new coupling. Some external signs that indicate potential coupling failure include: * Abnormal noise, such as screeching, squealing or chattering * Excessive vibration or wobble * Failed seals indicated by lubricant leakage or contamination.[2] Checking the coupling balance Couplings are normally balanced at the factory prior to being shipped, but they occasionally go out of balance in operation. Balancing can be difficult and expensive, and is normally done only when operating tolerances are such that the effort and the expense are justified. The amount of coupling unbalance that can be tolerated by any system is dictated by the characteristics of the specific connected machines and can be determined by detailed analysis or experience.

Going Green Essay

Going Green Essay Going Green Essay Operations Management 12/21/2012 Going Green and the Building Industry The popularity of green living has increased significantly over the years. No industry has been impacted more by green initiatives than the building industry. â€Å"In 2010, a third of all new commercial construction was green, amounting to a $54 billion market for commercial green buildings† (Pentland, W.). With this discussion we will review how green initiatives have shaped and continue to shape the operations of the construction industry. â€Å"By 2015, green buildings in the commercial sector are expected to triple, accounting for $120 billion to $145 billion in new construction and $14 billion to $18 billion in major retrofit and renovation projects† (Pentland, W.). To understand how building operations have been impacted by green demand we need to review these green building objectives and initiatives. Founded in 1993, The US Green Building Council (USGBC) is the authority set in place to coordinate and monitor the nation’s sustainable building practices. It is committee based, member-driven, and consensus-focused. To assist in the administration of these practices the USGBC has set up a green building rating system known as Leadership in Energy and Environmental Design (LEED). LEED rates projects based on some of the following initiatives; Sustainable Sites, Water Efficiency, Energy Atmosphere, Material Resources, Indoor Environmental Quality, and Innovation. LEED projects are qualified into the following certifications Certified, Silver, Gold, and Platinum. Designing and building a Gold or Platinum project will have significant more development expense and commitment than Certified and Silver projects but the reward and recognition have substantial benefits. Consumer and business demand are trending toward sustainability, energy efficiency, and overall green living practices. Many tenants are even willing to pay a premium for space in green buildings. One of the benefits is that employees will be more productive (Pentland). Devel opers are responding to and meeting this demand. Google also understands consumer needs. Google has offered a $3 million grant to the USGBC to support green building efforts. With this grant the USGBC plans to conduct further scientific research on building materials along with pushing for more material content transparency (Post, N. Catinella, R.). Traditional data centers have a high energy demand and commercial buildings as a whole are responsible for consuming a great amount of energy derived from fossil fuels. HP has the goal of developing/operating a data center that would consume zero net energy from the grid over the facility lifetime. The center is slated to have 30% greater efficiency and sourced renewable power. Through this project HP is stating they are committed to reducing greenhouse gas emissions and focusing on clean renewable energy (Post, N.). Modifying and retrofitting existing buildings to improve building efficiency is also a growing trend. President Obama and former President Clinton have introduced legislation to support retrofitting existing buildings through the Better Buildings Initiative (Easley, C.). This initiative is primarily targeted to large hotels and retail establishments. The synergy here is trifold; these buildings will lessen their carbon footprint, increase efficiency and lower annual operating costs. Green building is a trend that is now becoming the norm and developers are following suit through client demands. Architects, Engineers, and Consultants have also had to embrace the green building design in order to satisfy the demand. Some Architectural trends include designing open floor plans to increase daylight harvesting, roofing components with high solar reflective indexes to keep buildings cooler, drought tolerant landscaping, and requiring the use of sustainable/renewable materials. Mechanical and Plumbing Engineers are focusing on issues like water

Carbon Tax Conclusion

My final argument will be based on the effectiveness of this tax: The tax will have no significant impact on greenhouse gas emissions. It has been claimed that an Australian carbon tax will have no significant impact on the level of greenhouse gases in the earths atmosphere. This claim has been made on two bases. Firstly that it is unlikely to succeed in significantly reducing Australian greenhouse gas emissions and secondly, that even if these emissions were to stop completely this would have no useful effect on world greenhouse gas emission rates. Critics of a carbon tax for Australia argue that it will damage our economy without reducing climate change. The independent think tank, the Institute of Public Affairs (IPA) has stated that the proposed tax, although burdensome and damaging is not sufficiently large to force reinvestment in different forms of power generation. In a media released issued on March 2, 2011 and published in The Age, the IPA stated, The price itself, while severely harming the carbon-intensive, coal-based generators, would not force their premature departure from supply, which would be necessary to leave a gap for new gas generators. The IPA Review in September 2008 included the following response to Kevin Rudds proposed emissions trading scheme, Australia contributes 1. 1 per cent of total global greenhouse gas emissions. Our contribution is dwarfed by big emitters like the United States which contributes nearly 21 per cent, China which contributes 17 per cent, and Russia which contributes just over 5 per cent. All in all, there is no positive outcome for this tax, yes it is true that it reduces greenhouse gases, but things cannot always be solved with money. If we, as the Australian people want to make our environment cleaner, we should not just pay up to the government to clean our environment, we live in it, so we must put in some effort to prevent this ongoing issue. Thank you.

What are the strengths and weaknesses of seeing organizations as Essay - 1

What are the strengths and weaknesses of seeing organizations as purely rational configurations - Essay Example This study will be centered towards analyzing strengths and weakness of considering an organizational configuration as purely rational. There is no such definition that can precisely explain the concept of organizational behavior. Organizational theory can be stated as a concept that helps in studying system of formal organizations and their relationship with external environment. There are various concepts which are included in such study such as leadership, organizational development, organizational behavior, organizational and industrial psychology, human resource studies and management. Organizations have developed from past many years and during due course of time people have witnessed which of them are best firms. Rationalization or scientific management, division of labor and bureaucracy are some well known organizational theories. The term rational basically indicates making a conscious decision and not getting influenced by emotions. Absence of emotional aspect might result into an inappropriate organizational functioning. This study will be focused on determining advantages of rational perspective of a firm and its possible negative consequences. There are two significant factors of rational organizational like formalization and goal specification. Goal specification can be stated as forming guidelines in order to complete tasks and allocate resource appropriately. On the other hand, formalization is a method adopted to standardize organizational behavior. These two procedures results into stable expectations and develops a rational system. In modern world the major area of concern for all firms is to offer equal opportunities to all team members and take practical decisions that are not based on emotional grounds or on any such experience. This study shall reveal dual perspective of purely rational organizations with the support of appropriate
