Collaborative Drug Therapy Management essays

Collaborative Drug Therapy Management essays It involves the relationship shared between Pharmacist and Physician towards managing the drug therapy. Collaborative drug therapy management is practiced whenever pharmacists work with physicians and other health professionals to solve patient and medication-related problems or make decisions regarding drug prescribing, monitoring and drug regimen adjustments. (Fuller, 1995; 15:15-47) Under the course of CDTM, pharmacists along with physician share mutual responsibility for the treatment and recovery of the patient. CDTM can be categorized into following activities i.e. commencing, modification, observing drug therapy, ordering and conducting lab test, assessment of response to therapy, awareness and counseling of patients, and administering medication. CDTM encourages the participation and contribution of the pharmacists towards patient welfare. It is a measure that guarantees checks on the credibility of the physician and pharmacist. The role of the general pharmacist has further refined, pharmacist no longer share the sole responsibility of drug distributor, rather now the present pharmacist is capable of offering services to the patient for deciding their dosage, remedial action on basis of test reports. However it has to be ascertained that physician and pharmacist share a perfect understanding regarding their roles and limitations, both at parallel should be respectful towards the responsibilities of either sides. Physicians task of diagnosis should be separated from the Pharmacists task of monitoring the treatment and modify it accordingly. A formally written agreement between physician and pharmacist is requisite. Such an agreement should well define the role and responsibilities to be handled by the individual profession. Such an agreement should absolutely restrict the role of physicians for supervising and diagnosis, and should make pharmacist responsible fo ...

History and Inventors of Beds and Mattresses

History and Inventors of Beds and Mattresses A bed is a piece of furniture upon which a person may recline or sleep, in many cultures and for for many centuries the bed was considered the most important piece of furniture in the house and a type of status symbol. Beds were used in ancient Egypt as more than a place for sleeping, beds were used as a place to eat meals and entertain socially. The Mattress Among the earliest beds were simple, shallow boxes or chests in stuffed or layered with soft bedding. Later, ropes or strips of leather were suspended across a wooden framework to create a soft basis to sleep on. By the 15th century, most beds were built upon these straps of support over timber. The mattress itself evolved to be a sort of bag filled fiber like straw or wool, and then covered in common, inexpensive cloth. In the mid 18th century, the cover became made of quality linen or cotton, the mattress cane box was shaped or bordered and the fillings available were natural and plenty, including coconut fibre, cotton, wool, and horsehair. The mattresses also became tufted or buttoned to hold the fillings and cover together and the edges were stitched. Iron and steel replaced the past timber frames in the late 19th century. The most expensive beds of 1929 were latex rubber mattresses produced by the very successful Dunlopillo. Pocket spring mattresses were also introduced. These were individual springs sewn into linked fabric bags. Waterbeds The first water-filled beds were goatskins filled with water, used in Persia more than 3,600 years ago. In 1873, Sir James Paget at St. Bartholomews Hospital presented a modern waterbed designed by Neil Arnott as a treatment and prevention of pressure ulcers (bed sores). Waterbeds allowed mattress pressure to be evenly distributed over the body. By 1895, a few waterbeds were sold via mail order by the British store, Harrods. They looked like, and probably were, very large hot water bottles. Due to lack of suitable materials, the waterbed did not gain widespread use until the 1960s, after the invention of vinyl. Murphy Bed Murphy Bed, the bedding idea of 1900 was invented by American William Lawrence Murphy (1876 to 1959) from San Francisco. The space-saving Murphy Bed folds into a wall closet. William Lawrence Murphy formed the Murphy Bed Company of New York, the second oldest oldest furniture manufacturer in the United States. Murphy patented his In-A-Dor bed in 1908, however, he did not trademark the name Murphy Bed.

History - Essay Example pite the English colonies not having representatives in parliament in England, by the end of seventeenth century all English colonies had some form of representative assembly which more or less resembled the House of Commons in structure and functions. McGeehan and Gall assert that there were four major landmarks that shaped American constitutional government: Magna carter (1215), Bill of Rights (1689), Common law and Bicameral legislature (3). The kings in England used to have absolute authority over subjects but the Magna carter made them subject to law giving parliament power over tax levies. To tame the powers of the King, it was necessary to establish Representative governments whereby the people had a say in governance. Such governments were thus vital to colonies in attracting investors. The Bill of Rights in 1689 limited the power of kings and queens further as it disallowed interference with parliamentary elections and debates and kings could not suspend laws or levy taxes without parliament consent. On the other hand, rights developed from common law protected citizens from tyrannical governments. England had a bicameral legislature comprising House of Lords comprising clergy and nobility and House of Commons for wealthy middle class. This was the method adopted by English colonists. Before settlement therefore, the colonists had the idea of a limited government (McGeehan & Gall 3-5). The colonists in New World wanted a government where people were first thus the establishment of representative governments with Virginia being the first to establish the House of Burgesses in 1619 (Ushistory.org). Other colonists followed by establishing assemblies. For example, Plymouth had the Mayflower Compact, Massachusetts had the General Court, Connecticut had Fundamental Orders of Government while Rhode Island operated on principle of separation of church and state (McGeehan & Gall 3-5). Colonies were headed by governor and council who had executive powers of

Television and family circle Essay Example | Topics and Well Written Essays - 1250 words

Television and family circle - Essay Example This essay seeks to examine family circles in relation to humanity’s appreciation of use of the television. As a point of departure, the media, television included characterizes the modern world in every aspect. It is from this point of view, an argument on the impacts of media of the family circles is founded (Sari and Shay, 11). At the first installation of the TV waves, back in 1950s. Most families thronged at the supplier’s centers provided the services. Almost seven decades down the line, the TV plays a critical role in humanity’s life (Annie, 7). The aspect of family circles will be undertaken from two perspectives, which include relationship between parents and relationship between parents (husband and wife), and their children. This consideration is critical for this study because the family circle is based on the members of the family who include the parents and children. The aspect of unity and division along the family circles is a primary consideratio n. Family circle based on the relationship between parents Parents form the stem of the family from which otter members sprout. The family is the foundation of a society. All the societal virtual and vices are closely correlated to the virtues and vices of family members because the very members form the society. Initially, the TV was an instrument that united a family brought understanding and consequent societal harmony (Annie, 7). Over time now, that the social media instruments is playing roles as directed by those in the pedal. Programs that promoted morality, unity, dignity and other virtues have slowly declined and replaced by violent and crime oriented movies. In essence, every form of immorality is increasing each day with predetermined movies aired in our TVs. This implies that, there is a need for regulation or selection of programs to watch. As the televisions have come to absorb numerous socializing purposes of the family, they have provided us images of the family, whi ch may act as benchmarks by which we measure our own experiences. The seductively pragmatic portrayals of a family life in the wake of Television era may be the basis for our most popular and pervasive (Spigel, 75). The images such as violence, divorce, alcoholism and abuse seen in most families is a clear reflection of the mass media produced and distributed images shaped in a manner constrained by other features of the media world. They stems from the institutional needs, policies and interests of major needs. This implies that the primary media centers in a country can air what they deem moral right in their own facet, but in the real sense, they are immoral and preach division amongst the families who watch such programs (Spigel, 76). Gender based violence against women is a product of the media and the TV in particular. In the world of mass media, men exceed women by a ratio of seventy-five percentage to twenty-five percentage. This fact alone makes the world of primary media a s â€Å"man’s world† in which much action rotates around matters of power. This world is mostly governed by violent demonstrations of power characterized by the traditional emblematic platforms of authority and control, which naturally outside of home and family. Although, most of the violence occurs at homes, the familial setting does not lend itself to the societal communication of violence. Home and family

Upton Sinclair :: essays research papers

Upton Sinclair was an American writer whose works reflects not only the inside but also the socialists view on things. Upton sinclair was born in Baltimore, Maryland. He was born into a family which held to it’s Southern aristocracy in every thing that was done. When Sinclair was ten years old, the family packed up and moved to New York City ( Where there were more opportunities to succeed ). Upton Beall Sinclair began writing when he was 15 years old. He mostly wrote ethnic jokes and fiction for a fun magazine. He wrote these silly stories and jokes in order for the magazine to pay for his studies at New York City College. After he was done at New York City College, in 1897, he enrolled at Columbia University. By this time, Upton was putting out many novels and respected works. He was already being realized as one of the greatest writers of his time. Upton was putting out up to two novels per week. This was unheard of at this point in time. During these years he wrote Clif Faraday stories such as "Ensign Clarke Fitch." He was also writing Mark Mallory Stories like "Lieutenant Frederick Garrison" for boys’ weekly magazine. His writing was on the right track, but he still didn’t have that one book to put him over the top. In 1900 Sinclair married his first wife. This was a start of a whole new era of writing for him. By 1904 Sinclair was moving toward a realistic fiction type of writing. He had become a regular reader of the "Appeal to Reason", which was a popular socialist-populist weekly magazine at that time. Upton’s big break came in 1906 when he published a book called, " The Jungle." As a writer this is where Sinclair gained most of his fame. This book gave him not only fame, but it also led to the Pure Food and Drug Act in 1906. This book had the deepest impact since Harriet Stowe’s Uncle Tom’s Cabin. The books popularity enabled Sinclair to establish and support the socialistic Helicon Home Colony in Englewood, N.J. However the popularity of his type of writing fell away after that year. After " The Jungle" was written it set off many sim ilar studies of a group, and industry. or a region. Among some of them were: "The Metropolis" (1908) which was a exploration of New York people, "King Coal" (1917) which was a story about the Colorado Mining strike of 1914, and "Oil!" which was considered one of Sinclair’s most influential writings.

Bioremediation

BIOREMEDIATION Bioremediation is such type of technology in which microorganism, fungi, bacteria, plant and there is use to convert polluted condition in to original condition. Through bioremediation process microorganism act on pollutant or on chemicals due to which pollution occur and help that thing to come back in its original condition. Bioremediation is an option to offers the possibility to destroy or renders various harmful thing through natural biological activity. PRINCIPLES OF BIOREMEDIATION Bioremediation is the field of environmental biotechnology . y definition bioremediation is the use of microorganism, to degrade environment pollutant in to less toxic form. in this microorganism may be indigenous to a contaminant area or may be isolated from different area and brought to that area. Microorganisms start utilizing toxic substance and convert in to non toxic form from toxic form. In bioremediation metabolic process is also involved through which different enzyme release and act on toxic substances or on contaminants due to this biodegradation occur. When microorganism bought to contaminated or polluted site to enhance degradation that process is called bioaugmentation. For bioremediation to be effective, microorganism must enzymatically attack the pollutants and converts them in to non toxic form. n Bioremediation has its limitation, some contaminants such as chlorinated organic compound and aromatic hydrocarbon are resistant to microbial attack . bioremediation techniques are typically more economical than traditional method. FACTORS OF BIOREMEDIATION These factors include the existence of a microbial population capable of degrading the pollutants, the availability of contaminants to the microbial population, the environment factor (soil,temperature,pH,the presence of oxygen or other electron acceptor, and nutrients. ) MICROBIAL POPULATION FOR BIOREMEDIATION PROCESS Microorganism isolated from from any environment condition. microbes adapt nd grow at subzero temperatures ,as well as extreme heat, in water with excess of oxygen and in anaerobic condition,with the presence of hazardous condition or hazardous compound or any waste stream. the main requirements are an energy source and a carbon source. because of microbes and other biological system ,these can be used to degrade or remediate environmental hazards. Microbes can be divide in to groups according to their activity and condition. Anaerobic- in the absence of oxygen. naerobic bacteria cannot used frequently as a aerobic bacteria. There is an increa sing interest in anaerobic bacteria use for bioremediation of polychlorinated biphenyls (PCBs)in river sediment,ination of dechlorination of solvent trichloroethylene(TCE),and chloroform Lingninolytic fungi-fungi such as the white rot fungus phanaerochaete chrysosporium have the ablity to degrade an extremely diverse range of persistent or toxic environmental pollutants. Common substrate used include starw,sawdust,or corn cobs. Methylotrophs-aerobic bacteria that grow utilizing methane for carbon and energy. the initialenzyme in the pathway for aerobic degradation,methane monooxygenase,has a broad substrate range and active against a wide range of compounds ,including the chlorinated aliphatics trichloroethylene and 1,2-dichloroethane For degradationnit is necessary that bacteria and contaminant in proper contact and in proper amount.

Their growth and activity must be stimulated. Biostimulation usually involves the addition of nutrients and oxygen to help indigenous microorgan- isms. These nutrients are the basic building blocks of life and allow microbes to create the necessary enzymes to break down the contaminants. All of them will need nitrogen, phosphorous, and carbon (e. g. , see Table 2). Carbon is the most basic element of living forms and is needed in greater quantities than other elements. In addition to hydrogen, oxygen, and nitrogen it constitutes about 95% of the weight of cells. Table 2 Composition of a microbial cell.

Although microorganisms have been also isolated in extreme conditions, most of them grow optimally over a nar- row range, so that it is important to achieve optimal conditions. If the soil has too much acid it is possible to rinse the pH by adding lime. Temperature affects bio- chemical reactions rates, and the rates of many of them double for each 10  °C rise in temperature. Above a certain temperature, however, the cells die. Plastic covering can be used to enhance solar warming in late spring, summer, and autumn. Available water is essential for all the living organisms, and irrigation is needed to achieve the optimal moisture level. The amount of available oxygen will determine whether the system is aerobic or anaerobic. Hydrocarbons are readily degraded under aerobic conditions, whereas chlorurate compounds are degraded only in anaerobic ones. To increase the oxygen amount in the soil it is possible to till or sparge air. In some cases, hydrogen peroxide or magnesium peroxide can be introduced in the environment. Soil structure controls the effective delivery of air, water, and nutrients. To improve soil structure, materials such as gypsum or organic matter can be applied. Low soil permeability can impede move- ment of water, nutrients, and oxygen; hence, soils with low permeability may not be appropriate for in situ clean-up techniques. BIOREMEDIATION STRATEGIES Different techniques are employed depending on the degree of saturation and aeration of an area. In situ techniques are defined as those that are applied to soil and groundwater at the site with minimal distur- bance. Ex situ techniques are those that are applied to soil and groundwater at the site which has been removed from the site via excavation (soil) or pumping (water). Bioaugmentation techniques involve the addition of microorganisms with the ability to degrade pollutants. In situ bioremediation These techniques [11,12] are generally the most desirable options due to lower cost and less disturbance since they provide the treatment in place avoiding excavation and transport of contaminants. In situ treatment is limited by the depth of the soil that can be effectively treated. In many soils effective oxy- gen diffusion for desirable rates of bioremediation extend to a range of only a few centimeters to about 30 cm into the soil, although depths of 60 cm and greater have been effectively treated in some cases. The most important land treatments are: Bioventing is the most common in situ treatment and involves supplying air and nutrients through wells to contaminated soil to stimulate the indigenous bacteria. Bioventing employs low air flow rates and provides only the amount of oxygen necessary for the biodegradation while minimizing volatiliza- tion and release of contaminants to the atmosphere. It works for simple hydrocarbons and can be used where the contamination is deep under the surface. In situ biodegradation involves supplying oxygen and nutrients by circulating aqueous solutions through contaminated soils to stimulate naturally occurring bacteria to degrade organic contaminants. It can be used for soil and groundwater. Generally, this technique includes conditions such as the infil- tration of water-containing nutrients and oxygen or other electron acceptors for groundwater treatment. Biosparging. Biosparging involves the injection of air under pressure below the water table to increase groundwater oxygen concentrations and enhance the rate of biological degradation of contam- inants by naturally occurring bacteria. Biosparging increases the mixing in the saturated zone and there- by increases the contact between soil and groundwater. The ease and low cost of installing small-diam- eter air injection points allows considerable flexibility in the design and construction of the system. Bioaugmentation. Bioremediation frequently involves the addition of microorganisms indigenous or exogenous to the contaminated sites. Two factors limit the use of added microbial cultures in a land treatment unit: 1) nonindigenous cultures rarely compete well enough with an indigenous population to develop and sustain useful population levels and 2) most soils with long-term exposure to biodegrad- able waste have indigenous microorganisms that are effective degrades if the land treatment unit is well managed. Ex situ bioremediation Ex situ bioremediation These techniques involve the excavation or removal of contaminated soil from ground. Landfarming is a simple technique in which contaminated soil is excavated and spread over a pre- pared bed and periodically tilled until pollutants are degraded. The goal is to stimulate indigenous biodegradative microorganisms and facilitate their aerobic degradation of contaminants. In general, the practice is limited to the treatment of superficial 10–35 cm of soil. Since landfarming has the potential to reduce monitoring and maintenance costs, as well as clean-up liabilities, it has received much atten – leum hydrocarbons they are a refined version of landfarming that tend to control physical losses of the contaminants by leaching and volatilization. Biopiles provide a favorable environment for indigenous aerobic and anaerobic microorganisms. Bioreactors. Slurry reactors or aqueous reactors are used for ex situ treatment of contaminated soil and water pumped up from a contaminated plume. Bioremediation in reactors involves the pro- cessing of contaminated solid material (soil, sediment, sludge) or water through an engineered con- tainment system. A slurry bioreactor may be defined as a containment vessel and apparatus used to cre- ate a three-phase (solid, liquid, and gas) mixing condition to increase the bioremediation rate of soil- bound and water-soluble pollutants as a water slurry of the contaminated soil and biomass (usually indigenous microorganisms) capable of degrading target contaminants. In general, the rate and extent of biodegradation are greater in a bioreactor system than in situ or in solid-phase systems because the contained environment is more manageable and hence more controllable and predictable. Despite the advantages of reactor systems, there are some disadvantages. The contaminated soil requires pre treat- ment (e. g. , excavation) or alternatively the contaminant can be stripped from the soil via soil washing or physical extraction (e. g. , vacuum extraction) before being placed in a bioreactor. Table 4 summarizes the advantages and disadvantages of bioremediation. Table 4 Summary of bioremediation str ategies.

Microbes able to degrade the con- taminant increase in numbers when the contaminant is present; when the contaminant is degrad- ed, the biodegradative population declines. The residues for the treatment are usually harmless products and include carbon dioxide, water, and cell biomass. †¢Theoretically, bioremediation is useful for the complete destruction of a wide variety of contam- inants. Many compounds that are legally considered to be hazardous can be transformed to harm- less products. This eliminates the chance of future liability associated with treatment and dispos- al of contaminated material. †¢Instead of transferring contaminants from one environmental medium to another, for example, from land to water or air, the complete destruction of target pollutants is possible. †¢Bioremediation can often be carried out on site, often without causing a major disruption of nor- mal activities. This also eliminates the need to transport quantities of waste off site and the poten- tial threats to human health and the environment that can arise during transportation. Bioremediation can prove less expensive than other technologies that are used for clean-up of hazardous waste. Disadvantages of bioremediation †¢Bioremediation is limited to those compounds that are biodegradable. Not all compounds are sus- ceptible to rapid and complete degradation. †¢There are some concerns that the products of biodegradation may be more persistent or toxic than the parent compound. †¢Biological processes are often highly specific. Important site factors required for success include the presence of metabolically capable microbial populations, suitable environmental growth con- ditions, and appropriate levels of nutrients and contaminants. It is difficult to extrapolate from bench and pilot-scale studies to full-scale field operations. †¢Research is needed to develop and engineer bioremediation technologies that are appropriate for sites with complex mixtures of contaminants that are not evenly dispersed in the environment. Contaminants may be present as solids, liquids, and gases. †¢Bioremediation often takes longer than other treatment options, such as excavation and removal of soil or incineration. †¢Regulatory uncertainty remains regarding acceptable performance criteria for bioremediation. There is no accepted definition of â €Å"clean†, evaluating performance of bioremediation is difficult, and there are no acceptable endpoints for bioremediation treatments. PHYTOREMEDIATION Although the application of microbe biotechnology has been successful with petroleum-based con- stituents, microbial digestion has met limited success for widespread residual organic and metals pol- lutants. Vegetation- based remediation shows potential for accumulating, immobilizing, and transform- ing a low level of persistent contaminants. In natural ecosystems, plants act as filters and metabolize substances generated by nature. Phytoremediation is an emerging technology that uses plants to remove contaminants from soil and water [14–16]. The term â€Å"phytoremediation† is relatively new, coined in 1991. Its potential for encouraging the biodegradation of organic contaminants requires further research, although it may be a promising area for the future. We can find five types of phytoremediation techniques, classified based on the contaminant fate: phytoextraction, phytotransformation, phytostabilization, phytodegradation, rhizofiltration, even if a combination of these can be found in nature. Phytoextraction or phytoaccumulation is the process used by the plants to accumulate contami- nants into the roots and aboveground shoots or leaves. This technique saves tremendous remediation cost by accumulating low levels of contaminants from a widespread area. Unlike the degradation mech- anisms, this process produces a mass of plants and contaminants (usually metals) that can be transport- ed for disposal or recycling. Phytotransformation or phytodegradation refers to the uptake of organic contaminants from soil, sediments, or water and, subsequently, their transformation to more stable, less toxic, or less mobile form. Metal chromium can be reduced from hexavalent to trivalent chromium, which is a less mobile and noncarcinogenic form. Phytostabilization is a technique in which plants reduce the mobility and migration of contami- nated soil. Leachable constituents are adsorbed and bound into the plant structure so that they form a stable mass of plant from which the contaminants will not reenter the environment. Phytodegradation or rhizodegradation is the breakdown of contaminants through the activity existing in the rhizosphere. This activity is due to the presence of proteins and enzymes produced by the plants or by soil organisms such as bacteria, yeast, and fungi. Rhizodegradation is a symbiotic rela- tionship that has evolved between plants and microbes. Plants provide nutrients necessary for the microbes to thrive, while microbes provide a healthier soil environment. Rhizofiltration is a water remediation technique that involves the uptake of contaminants by plant roots. Rhizofiltration is used to reduce contamination in natural wetlands and estuary areas. In Table 5, we can see an overview of phytoremediation applications. Table 5 Overview of phytoremediation applications.

There are some limitations to the technology that it is necessary to consider carefully before it is selected for site remediation: long duration of time for remediation, potential contamination of the vegetation and food chain, and difficulty establishing and maintaining vegetation at some sites with high toxic levels. .

Dirty Pictures (Film Analysis)

The film Dirty Pictures released on year 2000 is loosely based on the story of Robert Mapplethorpe and his photography in late 1980's. Most photos of the late photographer Robert Mapplethorpe is actually uncontroversial however few of them– some sadomasochistic in nature– seem to offend. The inclusion of these provocative and seemingly offensive pictures in art exhibit has been highly criticized by the authority and feasted by the local media.Bennis Barrie, the curator of the Cincinnati Arts Center is inevitably accused of promoting pornography as he displays Mapplethorpe's naked images and graphic displays of homosexual offensive activities in Cincinatti art museum. Barrie initially knows that some of Mapplethorpe's photography may receive negative criticisms because of its provocative depictions of humans' mutual sensuality however as a curator he recognized that art encompasses a diverse range of human activities, creations and emotions. He believes that an artist de serves a freedom of expression.However Mapplethorpe photographs became the center of controversy when these were exhibited at the Cincinnati Contemporary Arts. Dennis Barrie who is the Museum director was being accused and condemned by the right wing conservatives. The rest of the film revolves in public debate towards how freedom of expression should be applied. The character of Barrie in the initial part of the movie is being portrayed as a modest and ordinary man who have a simple lifestyle. However after the exhibit, he was suddenly thrown into extraordinary circumstances as he deals with the enormous pressures of ugly public debate.He faced personal intimidation since his reputation and career were at stake. Furthermore, the issue pressed against him affected the emotional aspects of his family. The film effectively illustrates the emotions of a couple struggling to decide and do the right thing while dealing with the political pressures brought by the issue of displayed sensua l photographs. Though Barrie comes off as a man sophisticated and knowledgeable about contemporary arts but he is a little bit innocent about his stand since he was faced with unreasonable political pressures.The involvement of big conservative figures made this issue highly politicized. As a result, the jury who are also heroes of this story, experienced personal pressures of their own. At the end however they manage to navigate their way to the right decision after Barrie made a profound kind of speech about freedom of expression. Even if Barrie was being acquitted in the film, the local conservative group believes that this trial would have a chilling effect on future art exhibitions.Since freedom of expression has been positively justified in the film, there is a great possibility that curators and artists will always make an excuse to not restrict them in any kinds of mode of expression since this is after all their right. However, the conservatives subtly stand that the author ity should give restrictions especially in displaying sexually explicit photos to avoid public intimidation. The film inevitably shows Mapplethorpe controversial photos. A number of the actual Mapplethorpe's photos that were the heart and reason of the controversy were used in production.Though the photos are shown in shortcuts but the film allows the viewers to have a glimpse to both the controversial photos and the extraordinary beauty and story of all the photos in general. Apparently, he is not only interested to capture humans sexuality but his portraits, photos of flowers and landscapes illustrate his love in beauty. Mapplethorpe's â€Å"The Perfect Moment† collections air different angles of expression. His photographs were not confined in nudity however the authorities only favored and noticed one side by giving obscenity charges against the curator.Since big people also offered their own perspective towards the provocative photographs, it seems that the issue became politically motivated. Meanwhile, the film also looks like a documentary one since the filmmakers highlights new interviews from cultural and conservative figures about their personal perceptions in the issue. Meanwhile the filmmakers in the movie also incorporated many inter cut scenes from the original events collected from the archives of the local media (e. g. the trial and that attempted closing down of the art museum).The movie demonstrates that the beauty of art depends on how people perceive it. Their level of appreciation depends on their personal tastes, values, cultural and social orientation. In the movie, the characters were obviously divided by two– those who are open minded who believe that any kind of art depiction even in a sensational manner is just but a manner of expression that is natural to the artist; and the conservatives who believes that pornography negatively affect the viewers as it arouse malicious intent and emotions.However the film with the cha racter of Barrie reminds the public to uphold their right of expression and their right to choose what they art they would want to see and appreciate. No matter how disgusting and offensive a particular art might be, it has its every right to be exhibited. Any contemporary or classic art form is not exclusive to elite. The film subtly emphasized that an average and ordinary person can understand and appreciate art and art definitely do not only belong to specific few.

Edgar allen poes fall of the h

Edgar allen poes fall of the h The Fall of the House of Usher In Edgar Allen Poe's, "Fall of the House of Usher", Poe utilizes life-like characteristics of a decaying house to give it an unnatural or supernatural atmosphere, and in effect bring it's inhabitants to their impending doom.From the beginning of the story, the house is given a supernatural and unusual atmosphere, Usher's house, its windows, bricks, and dungeon are all used to portray a dismal and unusual atmosphere. When the narrator is approaching the house of his friend, Roderick Usher, Poe refers to the house as the "melancholy House of Usher" (718). This could be interpreted as the house being in a state of depression, in reality houses don't have a sense of feeling, Poe is giving the house life with these words. This is the first sign of a supernatural or unusual atmosphere.When the narrator is examining the building from the outside he describes what he is seeing and how he feels as he looks upon the house, "the vacant eye-like windowsupon a few r ank sedges-and upon a few white trunks of decayed trees-with an utter depression of soul which I can compare to no earthly sensation more properly than to the after-dream of the reveller upon opium" (718).Roderick MacRae

How to Get Recommendation Letters for Grad School

How to Get Recommendation Letters for Grad School Recommendation letters are a critical part of the graduate school application. If you are planning on applying to grad school, think about who you will ask for letters of recommendation well before you begin preparing your graduate school application. Make contact with professors during the first two years of college and develop relationships as you will rely on them to write recommendation letters that will land you a spot in the graduate program of your choice. Every graduate program requires applicants to submit recommendation letters. Dont underestimate the importance of these letters. While your transcript, standardized test scores, and admissions essay are vital components of your graduate school application, an excellent recommendation letter can make up for weaknesses in any of these areas. Why Do Graduate School Applications Require Recommendation Letters? A well-written recommendation letter provides admissions committees with information that isnt found elsewhere in the application. A recommendation letter is a detailed discussion, from a faculty member, of the personal qualities, accomplishments, and experiences that make you unique and perfect for the programs to which youve applied. A helpful letter of recommendation provides insights that cannot be gleaned by simply reviewing an applicants transcript  or standardized test scores. Moreover, a recommendation can validate a candidates admissions essay. Who to Ask? Most graduate programs require at least two, more commonly three, recommendation letters. Most students find choosing professionals to write recommendations difficult. Consider faculty members, administrators, internship/co-operative education supervisors, and employers. The people you ask to write your recommendation letters should: Know you wellKnow you long enough to write with authorityKnow your workDescribe your work positivelyHave a high opinion of youKnow where you are applyingKnow your educational and career goalsBe able to favorably compare you with your peersBe well knownBe able to write a good letter Keep in mind that no one person will satisfy all of these criteria. Aim for a set of recommendation letters that cover the range of your skills. Ideally, letters should cover your academic and scholastic skills, research abilities and experiences, and applied experiences (e.g., co-operative education, internships, related work experience). For example, a student who is applying to an MSW program or a program in clinical psychology might include recommendations from faculty who can attest to their research skills as well as recommendation letters from faculty or supervisors who can speak to their clinical and applies skills and potential. How to Ask for a Recommendation Letter There are good and bad ways of approaching faculty to ask for a letter of recommendation. For example, time your request well: dont corner professors in the hallway or immediately before or after class. Request an appointment, explaining that youd like to discuss your plans for graduate school. Save the official request and explanation for that meeting. Ask the professor if he or she knows you well enough to write a meaningful and helpful recommendation letter. Pay attention to their demeanor. If you sense reluctance, thank them and ask someone else. Remember that it is best to ask early in the semester. As the end of the semester approaches, faculty may hesitate because of time restraints. Also be aware of common mistakes students make when requesting recommendation letters, such as asking too close to the admissions deadline. Ask at least a month ahead of time, even if you dont have your application materials composed or your final list of programs chosen. Provide Information   The best thing that you can do to ensure that your recommendation letters cover all the bases is to provide your referees with all the necessary information. Dont assume that they will remember everything about you. For example, I might remember that a student is exceptional and an excellent participant in class but I may not remember all of the details when I sit down to write, such as how many classes the student took with me and extracurricular interests (such as being active in the psychology honors society, for example).  Provide a file with all of your background information: TranscriptResume or curriculum vitaeAdmissions essaysCourses youve taken with themResearch experienceInternship and other applied experiencesHonor societies to which you belongAwards youve wonWork experienceProfessional goalsDue date for the applicationCopy of the application recommendation forms (if a paper/hard copy letter is required and if the forms are provided by the institution)List of programs to which you are applying (and have them send email requests for recommendations early, well before the deadline) Confidentiality The recommendation forms supplied by graduate programs require you to decide whether to waive or retain your rights to see your recommendation letters. As you decide whether to retain your rights, remember that confidential recommendation letters tend to carry more weight with admissions committees. In addition, many faculty will not write a recommendation letter unless it is confidential. Other faculty may provide you with a copy of each letter, even if it is confidential. If you are unsure of what to decide, discuss it with your referee. As the application deadline approaches, check back with your referees to remind professors of the deadline (but dont nag!). Contacting the graduate programs to inquire whether your materials were received is also appropriate. Regardless of the outcome of your application, be sure to send a thank you note once you have determined that faculty have submitted their letters.

How you can enrich our diverse and inclusive community Essay

How you can enrich our diverse and inclusive community - Essay Example Therefore, it aims to give the best service students and employees can possibly experience so that in a mutual, though usually unspoken understanding, everyone would do his best to do what is expected. As a student, I understand that I am expected to do my responsibilities not only for myself but for the school and community as well. In order to support the vision of the school, I commit myself to an understanding of diversity and being respectful of the rights of everyone I engage with, whether students, professors or staff members. I understand that every person has his/her abilities and capabilities and that I am able to learn from them in different manners so, I want to enter the school with great expectation that each minute I spend with the people here, would add to my knowledge and wisdom. Being a part of the vision, I think I can also be a source of information with my life experiences that brought me to a deeper understanding about life and my motivations of becoming an integral part of the school. Understanding that students and employees come from various races, I can contribute to an inclusive community by respecting other races and creating a welcoming atmosphere for them in my presence. I can do my best to work hard in order to eliminate any discriminative words or actions rather have other people help me be molded to my highest potentials, with the diversity of culture, abilities and capabilities other races possess. I think I can also make a commitment to leadership which means I do not have to be in a recognized position in order to do my obligations as a concerned citizen but that I can contribute to leadership by having the initiative to do what is right. As the school is committed to excellence, I will also do my best not only to acquire knowledge and experience in the school but to join in the commitment of the school and aim to use all my potentials in the attainment of the said goal. I can commit myself not only to the highest

Eng lit Essay Example | Topics and Well Written Essays - 1250 words

Eng lit - Essay Example The attempt to "absorb America" that Deveare speaks of is perhaps impossible because of the sheer range of peoples, experiences and ideas that exist within it. But perhaps that very impossibility is an example of the success of the project. Thus is a person thinks that they have encapsulated the American experience and can hold it all within their viewpoint, they are bound to be excluding some groups and ideas that are not easy to absorb. A true absorbing of what it means to "be" American will involve a dizzying mixture of experiences which will overwhelm any one individual. The through-line which holds these selections together is the fact, paradoxically, that they are so different from one another. They hold a commonality of difference. But that difference is perhaps the best descriptor of the genuine American experience. "I sit down to write something of the life and character of Joaquin Murieta, a man as remarkable in the annals of crime as any of the renowned robbers of the Old or New World, who have preceded him." (p.1) The idea that a Mexican could be as "renowned" in anything as a white man, even in the dubious distinction of being an outlaw, was novel at the time this account was written. In many ways Ridge's account of the actions of Murieta contributed to the outlaw bandit image of the border states more than anything else. There is something Romantic to this hero, something which has remained to the present day. "I do this not for the purpose of contributing to any depraved taste for the dark and horrible in human action, but rather to contribute my mite to those materials out of which the early history of California shall one day be composed." Of course this appeal to "depraved tasted" is precisely what Ridge is doing. This quotation is useful because the legend and myths of such outlaws are as much a part of early American history as any of the lives of politicians. The mythology of the west is as important as the reality, indeed, it becomes part of the reality whether it is true or not. Harte, The Luck of Roaring Camp and Other Writings "There was commotion in Roaring Camp. It could not have been a fight, for in 1850 that was not novel enough to have called together the entire settlement. The ditches and claims were not only deserted, but "Tuttle's grocery" had contributed its gamblers, who, it will be remembered, calmly continued their game the day that French Pete and Kanaka Joe shot each other to death over the bar in the front room." (p.1) The myth of the violence of the American West, like many national myths, is based at least partly upon reality. This memorable opening shows the innate humor that could be gained from a community that is so violent that it barely notices two men shooting each other to death in a bar. In one sense, this quotation supports the great Hollywood Western myth that the whole of the West was made up of lawless towns in which coffins for the day's shooting deaths were lined up every day. "The assemblage numbered about a hundred men. One or two of these were actual fugitives from justice, some were criminal, and all were reckless. Physically they exhibited no indication of their past lives and character. The greatest scamp had a Raphael face, with a profusion of blonde
