The Invisible Poor Essay Example for Free
The Invisible Poor Essay There have been many writers, columnists, politicians, sociologists and economists who have written about the concept of poverty in the United States. Though their views often differ as to the causes, and solutions, the underlying commonality between all of those who have written about this issue remains that the current state of the American public is poorer than it has been in decades. The comparison of the following writers enables a reader to gain perspective on issues such as this. The ways in which different writers address, define, and respond to issues such as poverty, can allow for a reader to find their own understanding of the issue ââ¬â as well as its possible cure. à The following paper will seek to examine the lives of the invisible poor, the sociology behind such a society and at the end of the paper give a suggestion as to how poverty can be cured. à à à à à à à à à à à Margaret Andersen, Eugene Lewit, and James Fallows address the issue in differing ways ââ¬â however with much the same message. There is a problem with poverty in the United States. The concepts of the ââ¬Å"working poorâ⬠the ââ¬Å"disenfranchisedâ⬠as well as the general ââ¬Å"impoverishedâ⬠peoples of the United States are growing. à à à à à à à à à à à According to Andersen, the main problem is rooted in the residual effects of the pre-Civil Rights era. The accumulation of wealth over time, through inheritance and long term investment is lost on the groups which have been discriminated against since the dawn of the Untied States. Andersen states that ââ¬Å"racial exclusion in lending, housing segregation, and historical patterns of discrimination have created significant differences in the contemporary class standing of blacks and whitesâ⬠. (Andersen 184) This racial disparity was not limited to black and poor whites; it also included Hispanics and Asian-Americans. (Anderson 185) In the inequality involved in poor women in the workforce there is a sociological view of how this inequality is categorized:à Kinglsey Davis and Wilbert Moore gave sociology the theory of functionalism.à This theory states that every society separates its products, its money, and its services on the grounds of job difficulty and relevance to a society, or on the function that a specific job provides more for a society.à Due to a job and what gender performs that job function being more important to society or more functional, then society is willing to play the stratification game.à Since these functional jobs and the difference between the assumed capabilities of men or women performing them there is also stratification in monetary reward. à Society has a top echelon of jobs which they consider able to be filled only by a man or only by a women: The lower rung of this system includes mostly the feminine persuasion.à Functionalism fully believes in the rat race of society and exemplifies it through the power elite system and through gender inequality.à Functionalism states that there are critical jobs, ones so important to society (like saving a life) that the measurement of that personââ¬â¢s importance has to be reflected monetarily.à Functionalist expresses inequality through the bases of the nature of the occupational system.à As Davis and Moore state, ââ¬Å"Social inequality is thus an unconsciously evolved device by which societies insure that the most important positions are conscientiously filled by the more qualified personsâ⬠(Baldridge, 158). à à à à à à à à à à à With this reality it becomes increasingly clear that women are being discriminated against in the workforce, but more so if they are mothers.à Just because families, or single mothers are moving from welfare to work does not mean that they are above the poverty line.à Although earnings are seemingly increasing mothers who try to live on minimum wage cannot support a family of even one child. In the late 1990s, the study shows, families headed by working single mothers experienced rising earnings due to the strong economy, work supports like the Earned Income Tax Credit and child care, and a reformed welfare system. Yet these increased earnings were fully offset by a decline in the benefits that government safety net programs provide, leaving these families no better off as a group and pushing those who remained poor deeper into poverty (CBPP 2001). The rise in crime, increased rates of teenage pregnancy, drug use and the increased numbers of children and adults on government assistance are all attributed to the decline of the American family ââ¬â according to Popenoe. However, his assertions lacked any empirical support. This issue was taken up by Sharon Houseknecht and Jaya Sastry in 1996. The study conducted by the research team looked at the state of the family unit, and sought to find whether the ââ¬Å"declineâ⬠that Popenoe described was evident or not (Houseknecht 1996). The model that the research team used was based on Popenoeââ¬â¢s assertions that those family unites that are furthest away from the ââ¬Å"traditionalâ⬠view of family are ââ¬Å"more in declineâ⬠. The group took samples from four countries, Sweden, the United Stated, former West Germany, and Italy. Looking at non-marital birthrates, divorce rates, crime rates and child-wellbeing, the group found that, according to Popenoeââ¬â¢s model, Sweden had the greatest decline in the family unit ââ¬â followed by the United States in second. The problem that Andersen addresses is further exacerbated by the decline in ââ¬Å"real wages over the period from the 1970s to the late 1990sâ⬠. (Anderson 185) The fall in the value of the American dollar, coupled with the increased inflation meant that a worker making the median wage in 1989 made $13.22 an hour; however by 1997 that same level wage was only worth $12.63. (Anderson 185) The lower 80% of wage earners suffered more with a loss of 6.7% of their total wage power. à à à à à à à à à à à Eugene Lewit addresses the issue of poverty by writing about the number of children living in poverty. Lewit begins his appeal against the growing problem by noting that in 1991 there were 13.7 million children living in poverty in the Untied States ââ¬â a number that included an increase of nearly one million from the previous year. (Lewit 176) Lewit also noted that the total number of Americans living in poverty in 1991 was over 35 million people ââ¬â more than 10% of the total population. à à à à à à à à à à à The next issue that Lewit addresses is the number of problems faced by the impoverished children in comparison to their affluent counterparts. According to Lewit, ââ¬Å"poor children face increased risk of death, infectious and chronic illness, and injury from accidents and violenceâ⬠. (Lewit 176) These children also tend to live in conditions which are filled with violence, deteriorating housing, and disrupted living conditions ââ¬â which increase the likelihood of depression, low self-confidence, and conflict with peers and authority figures. (Lewit 176) à à à à à à à à à à à Lewit also bring attention to the problems in the definition of poverty. The federal thresholds which define poverty according to income, family size and location, suffer from, according to Lewit, ââ¬Å"inadequate adjustments for changing consumption patterns, inflation, and differing family sizes and structuresâ⬠. (Lewit 177) Lewit also states that the poverty guidelines fail to ââ¬Å"account for the substantial geographic variation in the cost of livingâ⬠. (Lewit 177) à à à à à à à à à à à Like Andersen, Lewit addresses the ââ¬Å"poverty gapâ⬠. According to Lewit, the amount by which the total poverty gap resided upon in 1991 was $37.2 billion. This meant that the lowest portions of the population of the United States were making nearly forty billion dollars less than the federal poverty level. This gap has long reaching repercussions, as these members of society also, as Lewit stated before, are more likely to become ill, injured or involved in violence ââ¬â which amounts to a further burden on the overall economy and social standing of any given area. à à à à à à à à à à à Fallows describes the technology boom of the early 1990s as ââ¬Å"the same disproportionate, commanding-heights effect on todays culture as Wall Streets takeover-and-junk-bond complex had 15 years ago, and as the biotech-financial complex presumably will 15 years from nowâ⬠ââ¬â and it grants large fortunes to small groups of people, many of whom began in lower or middle class families. The boom took people who were living as, or at least identifying with the impoverished members of American society and catapulted them into the ultra-elite ââ¬â amassing fortunes which often topped 100 million dollars. à à à à à à à à à à à Between these three writers, there is a common thread of though ââ¬â the poor are getting poorer. This fact is made worse by the disconnection of the wealthy and the poor. This disconnection is caused by the growing gap between the haves, and the have-nots. This gap increases the burden on the poor, mentally, as well as increases the difficulty in finding ways to remedy the causes of the vast amounts of poverty in the Untied States. à à à à à à à à à à à Fallows ended his article with the realization that problems, like poverty, ââ¬Å"are one thing when considered abstractly ââ¬â ââ¬Å"poverty, inequality, racism, problems stated as if they were debate topics. They can be altogether different when connected with human beings real or fictionalâ⬠. This is true in the fact that all too often the only time poverty is truly addressed in a forum which can eliminate it is during election campaigns ââ¬â and then only until that election is won. Experiment à à à à à à à à à à à In order to better provide housing, jobs, healthcare, etc. to the invisible poor the following experiment should be considered.à Take two groups of poor families; one as control, the other as a variable.à The control family will continue working the system for government aid, or living according to how they have always been living.à The second family, the variable family, will be given three items: a new housing unit (in a different part of the city or in the suburb), $2,500 for beginning expenses and getting out of debt expenses (with a one time meeting with a financial advisor), and a job interview for a qualifying job for each capable working member of the family. à à à à à à à à à à à The experiment will take place over a two year period, with updates on the family the first month, the third month, the sixth month, one year, one year and six months, and two years.à The elements of the experiment which will arise are amount of debt, if any family member has gone to college, where family members are in their schooling (i.e. grades, extra curricular activities, etc), how the jobs are going, if theyââ¬â¢ve advanced, if theyââ¬â¢ve maintained their job or gotten hired at a different place for a higher payer job, and finally their finances will be looked at. à à à à à à à à à à à The differences between these two families will be the backdrop to how, with a little bit of help, a family can overcome poverty.à The control group will give a recognition to how a family will continue to struggle without any help, or with the same maintenance from the government which they are already receiving.à The contrast of these two families, will hopefully, allow for a way in which other government programs can better assist getting rid of the invisible poor, and to strike a balance of wealth and financial freedom for families. à à à à à à à à à à à This experiment will seek to prove that the invisible poor is a great problem that needs to have an immediate solution.à The poor across the world is only increasing and it is with this experiment that a way in which to curtail poverty and give families and individuals hope to an economically fruitful future is found.

LSD :: essays research papers
à à à à à The book I chose is titled, ââ¬Å"The LSD Controversy.â⬠The author is Maurice S. Trashes, Ph.D. The call number is 615.78 and I read pages 1-50. à à à à à The first section of the book I read about deals with terminology. The other section I read about involves the general chemical characteristics of LSD. LSDââ¬â¢s complete name is D-lysergic acid diethylamide tartrate. Its abbreviation comes from the German Lyserg Sà ¤ure Diethylamid. The author goes on to define numerous terms for LSD such as hallucinogen, illusinogen, and fantastica. He then attempts to find the proper term for it. He believes that the term hallucinogen is inappropriate because real hallucinations are very rare. Although it is very widely used, he prefers illusinogen because according to S. Cohen, ââ¬Å"hallucinationsâ⬠are actually illusion. à à à à à As for the general characteristics of LSD, the author asks the question, ââ¬Å"What is LSD?â⬠From a chemical standpoint, LSD is a semisynthetic diethylamide that is prepared from lysergic acid. This is a naturally occurring chemical of the parasitic fungus called ergot. This grows in the seeds of rye and other grasses. Stoll and Hoffman were the first to synthesize it in 1938. Hoffman discovered its effects in 1943 when he accidentally sniffed a few micrograms; he thought he was going nuts. à à à à à LSD in a pure form is an odorless, colorless, and tasteless powder that is soluble in water and alcohol. Though it may be hard to detect, it is known as one of the most potent psychedelic drugs in existence. Roughly two pounds of the drug in powder form can supply ten million doses of 100 micrograms each which is sufficient for just about anyone. 100 micrograms is barely even visible! à à à à à Once it is has been taken by an individual, it is absorbed rapidly and distributed throughout the body. It has no problem passing through the blood-brain barrier and is almost completely metabolized by the body. It is excreted by the liver in the form of 2-oxy-LSD. à à à à à The case of whether or not LSD is addictive is argued in the book next. The reason it is so hard to determine if LSD is addictive or not is because there is no settled definition of addiction. Psychologists speak of psychic or emotional dependence while doctors talk about physical dependence. Then thereââ¬â¢s a distinction to be made on whether itââ¬â¢s the drug or the person that is addictive or addicted. To make it easier, the World Health Organization has recognized the ambiguity of the word ââ¬Å"addictionâ⬠and came up with the term ââ¬Å"drug dependence in 1965.

Managing Multinational Operations IP Essay
Organizations cannot remain ââ¬Å"staticâ⬠. They has to keep on moving breaking ââ¬Ëboundariesââ¬â¢ both geographically as well as economically, to actualize the opportunities and emerge successful. That is, with every firms wanting to expand their geographical reach and make an imprint in various markets, there will be enough opportunities for it, to initiate an entry into a foreign market. To initiate and actualize the entry, firms have to set targets and formulate various strategies according to the situation prevailing in those foreign markets. While formulating the strategies, the organizationsââ¬â¢ leader and the management team will firstly look at the factors that may aid them to make a successful entry. After analyzing the positive factors, the firms will or should have to analyze the challenges that may impede its entry. As every foreign market or country will have different political, social, economic conditions as well as different customers, competitors, prospective employees, etc, etc, there will be many challenges, which will block the firmsââ¬â¢ success. Also, there will be country specific challenges as well as industry specific challenges in those foreign markets. For example, the Asian country of China has some distinct aspects, which will surely act as a challenge for the new firms, who are planning to enter it In the earlier decades, the cheap Chinese products only entered various countriesââ¬â¢ markets. But, now seeing the potential of the Chinese economy and the market many foreign firms or foreign invested firms have entered or entering the Chinese markets. The other thing, which is enticing the foreign firms, is the huge population, which translates into the biggest market of the world. Apart from these two important aspects (high economic growth and huge market), the main thing that allows the foreign firms to enter China is the relaxation of many restrictions imposed by the Chinese Government. China being a Communist country functioned behind an ââ¬Å"Iron Curtainâ⬠, restricting the foreign firms to protect the home-grown firms. But, due to globalization and the resultant economic growth, the government saw the full potential of the Chinese market. ââ¬Å"Rising prosperity and a rapidly commercialising economy have transformed China into the worldââ¬â¢s most important emerging market ââ¬Å"(consume. bbk. ac. uk, n. d. ). So, Chinese government started to allow the entry of foreign firms. But, the main decision of the Chinese government which worked as the catalyst for more foreign entry is the relaxation of the restrictions, which was brought about by Chinaââ¬â¢s entry into World Trade Organization. But, even with all these favourable situations, the foreign firms entering China were challenged, restricted and regulated by the Chinese government and also by certain other factors. That is, even while allowing the foreign firms, the Chinese governmentââ¬â¢s policies and the existing local conditions challenges the retail firms and restricts it from becoming a success. The main challenge comes in the form of a new tax regime, which has taken away the privileges enjoyed by the foreign firms. The main aspect of this new tax regime is foreign invested firms and other Chinese-foreign joint ventures have to pay the land-use tax, equal or more than the Chinese companies. Before the introduction of this regime, the foreign firms are exempted from paying land-use tax, and were allowed to function and raise infrastructures on non-taxed lands. But, under the new regime, land-use or property-tax rate will be equal for both the local and the foreign developers, with the foreign firmsââ¬â¢ tax requirements tripling from the old rate set in 1988. This increase in land-use tax will surely be a challenge for the retail firms, as they have pay higher taxes according to the location of their infrastructure. Regional fragmentation of the tax structure is another tax related problem which is hampering the foreign firms. Regional fragmentation of finance regulation and importantly tax laws creates a kind of regional protectionism so that a foreign company with joint ventures in several locations may have to make a separate payment from each venture to the supplier (Huffman, 2003). Even though China is accelerating at a fast rate, the internal factor of corruption is impeding its flow and has turned out to be a major challenge for the foreign firms. ââ¬Å"With its economy soaring at around 10 percent a year for nearly three decades, Chinaââ¬â¢s ascendance seems unstoppableâ⬠¦Behind Chinaââ¬â¢s dynamism, however, lurk many dangers that could derail the Middle Kingdomââ¬â¢s re-emergence as a great power: environmental degradation, population agingâ⬠¦ and, above all, endemic corruptionâ⬠(Pei, 2007). Many Chinese departments particularly ones dealing with the foreign investment have become corrupted, with the government officials manning these departments openly demanding bribes. So, with corruption expanding its tentacles throughout China, the foreign firms think twice about entering the market. The existing firms also find the ritual of bribing the government officials an irritating at the same time costly exercise. These corrupt practices could be one of the difficult challenges for the foreign firms. On a final note, while researching about the Chinese market, I came across certain government policies on employee welfare, labor relations, etc, which were actually an antithesis of what our CEO firmly believes. I will include that information also in the report because the purpose of the report is to provide a realistic picture of the Chinese market, without ethical biases. The primary focus of any organization is to give a clean management based on preset ethics. If the management and the employees are ethically perfect, they will exhibit good discipline, hard work and thus high productivity. So, I will provide a realistic and ethically perfect report incorporating all the needed information. Although those aspects are different from my CEOââ¬â¢s point of view, those aspects could play a crucial role when our organization decides to enter the Chinese market. I am sure my CEO will see the larger picture and consider those aspects as well during the decision making process. Reference: consume. bbk. ac. uk. (n. d).

Interior design history Essay
The late Dorothy Draper who lived for eighty years was born to the family of Tuckenman in 1889 and died in 1969. She got married to Dr. George Draper in 1912. The family was blessed with kids. Dorothy Draper received no formal primary education. Far back in the middle 60s, Dorothy was credited as an excellent founder of interior design. She was a well respected designer. She used exceptional traditional materials and styles in designing. In the year 1939, Dorothy, drove by the passion to inspire the world around with the importance and practice of designing, she was an author of many designing books, one laying emphasis to how fun is generated from designing. The book subtitled ââ¬â ââ¬Å"How to Be Your Own Decoratorâ⬠received wide attentions in the modern works of interior design. Of the Designer Dorothy, the absence of formal education was not a barrier to the vision of exploring the diverse fields of art. She was inspired by the privileged endowment of pleasant natural environment she lived. A creative task of translating an abstract experience into visible objects for the relish of viewers. Secondly, the reckoning adventure into the designing world was not unconnected to her numerous travelling experience around the cities of Europe. The breakthrough came shortly after her wedding to Dr George Draper when she painstakingly took up the task of decorating their home to taste. The beautiful home received steadfast attentions from their visitors and led to the publicity of her great ability. The Works of Dorothy Draper Sequel to publicity of her home interior decoration, she was consulting for an architectural company (Owned by Franck L. Wright) who hired her on partnership. She was employed to decorate a gigantic 37 floors Hamphire House, a hotel in Manhatten; she had in historical records decorated cars for Packard Company. For Convair airplane manufacturing company, she also made her contribution therein. She was a specialized interior designer of places like clubs, restaurants, hotels, institutions such as hospitals before her demise thirty-nine years ago. Though much of her works were not surviving to the modern age, they were however, serving the foundation upon which modern tips were consulted for design finishing. Some of her works are in the monument of Metropolitan Museum of Art, in New York City, U. S. A (created by Donald Albrecht). Howard Johnson restaurants all over reflects the commissioning of Dorothy Draper as a color specialist, this is an important aspect in the act of designing/decoration. Recently, starting about two years ago till now the works of Dorothy is under exhibition. Pictures showing two of her best works exhibited in New York City Museum included that of ââ¬Å"the Arrowhead Spring Resorts and the Green Brier Hotelâ⬠. In December ââ¬â¢06 to June ââ¬â¢07, the exhibition at a Museum in Dallas also displayed a snapshot of her project in the Stoneliegh Hotel.

Babbitt essays
Babbitt essays The 1920s saw the rise of the true American consumer. For the first time in U.S. history more Americans lived in urban rather than rural areas. The nation prospered as a whole, but the wealth widened the gap between the rich and the poor. It was during this time that a great outpour of creative talent produced artists of all types who indicated the United States for being artistically barren. Authors such as Ernest Hemingway, F. Scott Fitzgerald, and Sinclair Lewis began to emerge and thus Babbitt was born. Sinclair Lewis, the first American to win the Nobel Prize for literature, created the true symbol of American life and values in the 1920s with his satirical character George F. Babbitt. Babbitt tells the tale of an average family living in the 1920s while accurately portraying American life and culture. With such a lively character as George Babbitt, it is hard for anyone not to enjoy this novel. Although a satire, Babbitt does deal with many real life situations which build up to Lewis thesis that no matter how hard people try they cannot change who they are. Through his use of detail, dialogue, and description Lewis is able to appeal to his readers emotionally, intellectually, and ethically. The Roaring Twenties marked a time of great prosperity. Everyone in America was trying to get a piece of the pie. Although he was well off, Babbitt did anything he could to get ahead in life, just as most people do today. Sinclair Lewis tries to create the average American by making him a middle-class, materialistic, hypocritical conformist. Lewis uses detail to make his character as real as possible; in fact detail is used throughout the novel so that the story would be believable and easy to relate to. With many mentions of jazz music, prohibition, and opinions of womens latest fashions being too short, the many details in Babbitt affect readers intellectually because they give the readers a feel for t...

Sea Urchins and Sand Dollars Are the Round Echinoderms
Sea Urchins and Sand Dollars Are the Round Echinoderms Sea urchins and sand dollars (Echinoidea) are a group of echinoderms that are spiny, globe or disk-shaped animals. Sea urchins and sand dollars are found in all the worlds oceans. Like most other echinoderms, they are pentaradially symmetrical (the have five sides arranged around a central point). Characteristics Sea urchins range in size from as small as a couple of inches in diameter to over a foot in diameter. They have a mouth located on their upper part of their body (also known as the oral surface) although some sea urchins have a mouth located towards one end (if their body shape is irregular). Sea urchins have tube feet and move using a water vascular system. Their endoskeleton consists of calcium carbonate spicules or ossicles. In sea urchins, these ossicles are fused into plates that form a shell-like structure called a test. The test encloses the internal organs and provides support and protection. Sea urchins can sense touch, chemicals in the water, and light. They do not have eyes but their entire body seems to detect light in some manner. Sea urchins have a mouth that consists of five jaw-like parts (similar to the structure of brittle stars). But in sea urchins, the chewing structure is known as Aristotles lantern (so named for the description of Aristotles History of Animals). The teeth of sea urchins sharpen themselves as theyà grind food. The Aristotles lantern encloses the mouth and the pharynx and empties into the esophagus which in turn connects to the small intestine and caecum. Reproduction Some species of sea urchins have long, sharp spines. These spines serve as protection from predators and can be painful if they puncture the skin. It has not been determined in all species whether the spines are venomous or not. Most sea urchins have spines that are about an inch long (give or take a bit). The spines are often rather blunt at the end although a few species have longer, sharper spines. Sea urchins have separate sexes (both male and female). It is difficult to distinguish between the sexes but males usually select different microhabitats. They are usually found in more exposed or higher locations than females, enabling them to disperse their spermatic fluid into the water and distribute it better. Females, in contrast, select more protected locations to forage and rest. Sea urchins have five gonads located on the underside of the test (although some species only have four gonads). They release gametes into the water and fertilization takes place in open water. Fertilized eggs develop into free-swimming embryos. A larva develops from the embryo. The larva develops test plates and descends to the seafloor where it completes its transformation into an adult form. Once in its adult form, the sea urchin continues to grow for several years until it reaches its mature size. Diet Sea urchins feed on algae for the most part although some species also feed occasionally on other invertebrates such as sponges, brittle stars, sea cucumbers, and mussels. Although they appear to be sessile (attached to the seafloor or substrate) they are capable of moving. They move over surfaces by way of their tube feet and spines. Sea urchins provide a food source for sea otters as well as wolf eels. Evolution Fossil sea urchins date back about 450 million years ago to the Ordovician period. Their closest living relatives are sea cucumbers. Sand dollars evolved much more recently than sea urchins, during the Tertiary, about 1.8 million years ago. Sand dollars have a flattened disk test, instead of the globe-shaped test sea urchins have. Classification Animals Invertebrates Echinoderms Sea Urchins and Sand Dollars Sea urchins and sand dollars are divided into the following basic groups: Perischoechinoidea - The members of this group were abundant during the Palaeozoic Era but today only a few members still survive. Most species of Perischoechinoidea became extinct during the Mesozoic Era.Echinoidea - The majority of living sea urchins belong to this group. Members of the Echinoidea first appeared during the Triassic Period.

Relationship between Theory and Application or Practice Research Paper
Relationship between Theory and Application or Practice - Research Paper Example It can be mentioned that the concepts related to the association between theory and practice has been the main focus among the psychologists and psychotherapists among others because it assists them to attain their respective research objectives. Although, the term theory is not used much in the context of any researches but the principles guide the theories in order to enhance its applicability in various fields (Fook, 2002). A theory is considered to be a representation or a collection of assumptions about a specific reality. Theories can either be explanatory or analytical. People tend to make use of the theories in order to anticipate the results of its actions and to make efficient decisions. Conversely, practice is considered to be an academic research which enhances any research methodology output. It can be affirmed that different theories have a tendency to guide or inform practice by offering direction for action as well as scope for decision making. In the context of psych otherapy, it is considered to be significant to be capable of intervening in the decision making process. In this similar context, it can be revealed that practice can also guide as well inform theory. The observant can gauge the action of others and hence offer feedback. Hence, it can be stated that there exists mutual association between theory and practice owing to the fact that an individual regularly tends to evaluate his/her own hypothesis and generates new meaning from previous experiences. Hence, on the basis of the above discussion, it can be stated that there needs to be a consistency between theory as well as practice. It is well identified that when the action of a person is aligned with his/her intention, the consistency is generally known as ââ¬Ëwalking your talkââ¬â¢. A person acting in a manner being consistent with his/ her intentions can be viewed as possessing integrity, while failure to do so is generally viewed as hypocrisy (Granick, 2005). A theory is sim ilar to the lens that assists a person in viewing experiences. The lens further tends to possess its focal strength along with the areas of misrepresentation. Identification of the relative strengths as well as shortcomings related to different theories has provoked the movement towards collective psychotherapies that summarizes multi-theoretical views. However, none of the theoretical views claim that theories as well as practices shall be aligned (Granick, 2005). One of the interesting facts related to theory and practice has been that they are at once both autonomous and inter-dependent. It can be observed that though the interests as well as the goals of the academics help in increasing the effectiveness, there lies genuine gap between theory and practice. It is argued that the communities tend to gain advantage from cross-fertilization of the people, work and ideas. It has been further identified that the gap arising between theoretical as well as practical views in the context of management learning has not been paid due attention from long period of time. Owing to the factors of increased globalization in businesses and the developments in technology, it has been viewed that there has been a major alteration in the social as well as in the economic environment which in turn forced the organizations all over the globe to make significant changes in their organizational purpose as well as structure.Ã
