In Search of Room-Temperature Superconductors

Imagine a world in which magnetic levitation (maglev) trains are commonplace, computers are lightning-fast, power cables have little loss, and new particle detectors exist. This is the world in which room-temperature superconductors are a reality. So far, this is a dream of the future, but scientists are closer than ever to achieving room-temperature superconductivity. What Is Room-Temperature Superconductivity? A room temperature superconductor (RTS) is a type of high-temperature superconductor (high-Tc or HTS) that operates closer to room temperature than to absolute zero. However, the operating temperature above  0  °C (273.15 K)  is still well below what most of us consider normal room temperature (20  to  25  Ã‚ °C). Below the critical temperature, the superconductor has zero electrical resistance and expulsion of magnetic flux fields. While its an oversimplification, superconductivity may be thought of as a state of perfect electrical conductivity. High-temperature superconductors exhibit superconductivity above  30  K (−243.2  Ã‚ °C). While a traditional superconductor must be cooled with liquid helium to become superconductive, a high-temperature superconductor can be cooled using liquid nitrogen. A room-temperature superconductor, in contrast, could be cooled with ordinary water ice.   The Quest for a Room-Temperature Superconductor Bringing up the critical temperature for superconductivity to a practical temperature is a holy grail for physicists and electrical engineers. Some researchers believe room-temperature superconductivity is impossible, while others point to advances that have already surpassed previously-held beliefs. Superconductivity was discovered in 1911 by  Heike Kamerlingh Onnes in solid mercury cooled with liquid helium (1913 Nobel Prize in Physics). It wasnt until the 1930s that scientists proposed an explanation of how superconductivity works. In 1933, Fritz and Heinz London explained the Meissner effect, in which a superconductor expels internal magnetic fields. From Londons theory, explanations grew to include the  Ginzburg-Landau theory (1950) and microscopic BCS theory (1957, named for Bardeen, Cooper, and Schrieffer). According to the BCS theory, it seemed superconductivity was forbidden at temperatures above 30 K. Yet, in 1986,  Bednorz and Mà ¼ller discovered the first high-temperature superconductor, a lanthanum-based cuprate perovskite material with a transition temperature of 35 K. The discovery earned them the 1987 Nobel Prize in Physics and opened the door for new discoveries. The highest temperature superconductor to date, discovered in 2015  by Mikhail Eremets and his team, is sulfur hydride (H3S). Sulfur hydride has a transition temperature around 203 K (-70  °C), but only under extremely high pressure (around 150 gigapascals). Researchers predict the critical temperature might be raised above  0  Ã‚ °C  if the sulfur atoms are replaced by phosphorus, platinum, selenium, potassium, or tellurium  and still-higher pressure is applied. However, while scientists have proposed explanations for the behavior of the sulfur hydride system, they have been unable to replicate the electrical or magnetic behavior. Room-temperature superconducting behavior has been claimed for other materials besides sulfur hydride. The high-temperature superconductor yttrium barium copper oxide (YBCO) might become superconductive at 300 K using infrared laser pulses. Solid-state physicist Neil Ashcroft predicts solid metallic hydrogen should be superconducting near room temperature. The Harvard team that claimed to make metallic hydrogen reported the Meissner effect may have been observed at 250 K. Based on exciton-mediated electron pairing (not phonon-mediated pairing of BCS theory), its possible high-temperature superconductivity might be observed in organic polymers under the right conditions. The Bottom Line Numerous reports of room-temperature superconductivity appear in scientific literature, so as of 2018, the achievement seems possible. However, the effect rarely lasts long and is devilishly difficult to replicate. Another issue is that extreme pressure may be required to achieve the Meissner effect. Once a stable material is produced, the most obvious applications include the development of efficient electrical wiring and powerful electromagnets. From there, the sky is the limit, as far as electronics is concerned. A room-temperature superconductor offers the possibility of no energy loss at a practical temperature. Most of the applications of RTS have yet to be imagined. Key Points A room-temperature superconductor (RTS) is a material capable of superconductivity above a temperature of 0  °C. Its not necessarily superconductive at normal room temperature.Although many researchers claim to have observed room-temperature superconductivity, scientists have been unable to reliably replicate the results. However, high-temperature superconductors do exist, with transition temperatures between  Ã¢Ë†â€™243.2  Ã‚ °C  and  Ã¢Ë†â€™135  Ã‚ °C.Potential applications of room-temperature superconductors include faster computers, new methods of data storage, and improved energy transfer.

The Birth Of America Is Well, The Biggest And Greatest

The birth of America is well, the biggest and greatest thing to ever happen to us. There are many things that led up to the 1865 era such as salutary neglect, the Constitution, the Louisiana Purchase, Manifest Destiny, and Slavery. Those are just a few things that America powered through to get where we are today. Our Forefathers attempted to rectify what some would consider harsh actions made by the kingdom of Britain in the mid 1700’s. The British didn’t take the American territories seriously and just saw them as colonies to be used and exploited in whatever way that best suited the kingdom’s interest. The morning of April 19, 1775 America was then no longer just negotiating for its rights, we were fighting for them.†¦show more content†¦By the end of the assembly of the Second Continental Congress, America would declare war on Britain. In Lexington in April of 1775 the British troops and colonial militiamen kicked off the armed conflict. By the summer the rebels were waging a full-scale war for their independence. France entered the American Revolution on the side of the colonists in 1778, turning what had been a civil war into an international conflict. French assistance helped the Continental Army force the British surrender in Yorktown, Virginia, in 1781. We had won our Independence. Though fighting would not officially end until 1783. The United States Constitution’s final draft was approved on September 17, 1787. It established America’s national government and fundamental laws, and guaranteed certain basic rights for its citizens. It was, however more than just a document. It would more importantly establish the form of government that would be utilized right up to modern day America. The framers of the Constitution knew that while government needed power in order to be effective, too much power could lead to abuses. So they kept government under control by dividing the power into two ways; Federal and State powers. The federal system of government was shared among state and national authorities. Some powers, such as establishing an educational system were known as reserve powers because they were reserved for the state.

Dark Rapture Essay Example For Students

Dark Rapture Essay In Native Speech, On the Verge and In perpetuity Throughout the Universe, Eric Overmyer manifested a extraordinary command over the tools of language: sound, syntax and image. None exhibited much control over, or interest in, the more mundane devices of the playwrights art. In Dark Rapture, which premiered at Seattles Empty Space Theater in May, Overmyers verbal dexterity is acute as ever, but this time its harnessed to a plot delivered by characters who seem driven by purposes of their own. Its by far Overmyers most satisfying play. Dark Rapture may not, however, earn its author the critical praise it deserves it certainly didnt in Seattle because it adheres so strictly to the rules of a genre. In the written arts, in film, in dance, in pop music, a creative artists submission to such rules earns no disrespect. In theatre, it seems we honor work created within rigid conventions only if the conventions are someone elses kabuki or kathakali, wayang or noh. Escape from the ordinary Dark Rapture is noir, the genre which crystallized in the 1940s novels and screenplays of Raymond Chandler and has intermittently borne fruit ever since in the hands of artists as various as Richard Condon and Wim Wenders. Good noir is rare on stageOvermyers own early In a Pigs Valise is congested, prankish hommage, dead on arrival. But his Dark Rapture is the most succesful stage essay in the form since Len Jenkinss marvelous, poetic Five of Us. Like many noir fictions, Dark Rapture is about escape: from the self, from the sane, from the ordinary. This time the escape hatch is offered by a fire that leaves the Berkeley Hills home of Ray and Julia Gaines a pile of smoldering rubble with a charred and unrecognizable corpse beneath it. Whose corpse is it: Rays, or a looters? Just where was Julia when the house burned down? And what happened to the brown-paper parcel Julia says she left in Rays custody? Did it go up in flames, too, with or without him? Any number of sinister people want to know. In classic noir manner, the story advances tableau by moody tableau from Baja bedroom to Key West bar deck to Tampas kitchenette, each offering its sharply etched character cameo, its fragment on information, its new complication, straight to a conclusion redolent with irony. Patsies and sleazeballs The performances were utterly attuned to the material. As a lifelong schlepper grabbing that one big chance, Peter Silbert made Ray a loser worth rooting for. As the froms obligatory good bad girl, bad good girl, and bad girl, Sally Smythe, Jessica Marlowe and Katie Forgette gave their archetypical roles individual flair. Particularly notable among those playing assorted gunsels, patsies, sleazeballs, wise-asses and loons were Rex McDowell as a mad Armenian hit-man, Robert Wright and David Pichette (poisonous lizard and rabid pekinese, respective) as businessman trafficking in non-standard merchandise, and David Mong as the mysterious Babcock, Rays sunnily implacable doom. The design was equally supportive. Peggy McDonalds supple arrangements of screens and Paul Chi-ming Loueys matte costumes under Michael Wellborns chiaroscuro lighting heightened Overmyers torrid imagery through contrast. David Pascals sound design holocaust and hurricane and all shadings between put a final polish on Empty Space artistic director Kurt Beatties perfectly paced staging. Few productions of new plays especially ones mounted on a minuscule budget by an artist heretofore best known as an actor-playwright are as assured as this one. Dark Rapture was commissioned and staged as part of the Empty Space ensemble project put together by Beattie to test a long-held conviction that authoritarian structures are ill-designed to produce first-rate theatre; that true extended collaboration is a lot more likely to produce a cultural artifact that has some lasting value for the society that produced it than any one-shot wiring together of egos, however brilliant individually. After only four months of concentrated work and just two productions, Beatties theory already seems amply confirmed in practice.

Reputation in the Crucible free essay sample

Reputation is the estimation or name of being, having, having done, something specified by the general opinion of either a private or public group of people. In Arthur Miller’s screenplay, The Crucible, Miller presents his opinions on the factual truth of the Salem Witch Trials. Various events in Arthur Miller’s screenplay reveal the theme of reputation as being a leading force in the developing plotlines of the story. By doing this, he brings a whole new point of view to the readers of his screenplay. Reputation was extremely important at the time, as in a town like Salem where social standing was tied to one’s ability to follow religious rules. If you had a good reputation, you were more likely to be an upright member of the church and a good Christian. In Puritan times being religious and following the rules of God meant everything. The reputations of many characters in the crucible including Abigail, John Proctor and Reverend Parris were defined by the many actions and dialogues throughout the play, the Crucible. We will write a custom essay sample on Reputation in the Crucible or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page A dialogue from Abigail reveals Arthur Millers’ insights on the role of reputation in the society of Salem. Abigail states, I want to open myself! I want the light of God; I want the sweet love of Jesus! I danced for the Devil; I saw him, I wrote in his book; I go back to Jesus; I kiss His hand. I saw Sarah Good with the Devil! I saw Goody Osburn with the Devil! I saw Bridget Bishop with the Devil! (Miller Act I) This quote from Abigail raises her position in society. By Abigail, doing this, the other girls follow; believing this will raise them also in the social ranking of their society. After hearing Tituba confess to witchcraft, Abigail sees this as an opportunity to get herself out of the spotlight, even though she was with the other girls in the forest. After clearing her name, she wanted to move the blame on, she starts accusing falsely the other people of being witches. When this was done, the other girls followed because of the success she had. These girls all cared about their reputation. With their reputation, they believe it is a way out from being trailed as a witch, as everyone else in Salem wishes to do. Abigail caused enough trouble in the court room ruining others reputations in order to save her own, but at the same time risks her own reputation. John Proctor, a farmer who lives outside the town had an affair with Abigail who is just a teenager early on in the screenplay, and is frightened to expose such a thing; he is afraid his name will be ruined. Earlier on in the play, Proctor has a chance to put a stop to the girls being accused of witchcraft; instead he sought to preserve his reputation from testifying against Abigail and revealing his scandalous affair. Towards the end of the play The Crucible, Proctors desire to keep and maintain his good name; leads him to make a courageous choice, by not giving into a faulty confession which leads to his death. Proctor says to Danforth, â€Å"I have given you my soul; leave me my name! † (Miller Act IV) This quote shows that by Proctor refusing to give up or surrender his name and reputation, he redeems himself for his earlier failure and dies with integrity. John Proctor confirms his decision saying to himself in Act IV that he has given his soul and wants to at least keep his name. Proctor gives his last orders as to not destroy his name, because his name means so much to him. He would rather die than live with the rest of the town knowing that he was convicted of seeing the devil and being a witch. In Act II, Proctor says to Putnam, â€Å"You cannot command Mr. Parris. We vote by name in this society, not by acreage. † This quote demonstrates what a big role a person’s name in the society brings to the rest of the town of Salem. Acreage, money or land is usually a way to critique a person, but in Salem, someone’s name or part in society is what they are held as in the eyes of the people. If you have a good reputation then you stand high in the town, but if your reputation is bad and you are convicted of being a witch, that could damage your reputation and status severely. In Act II, Parris says, â€Å"Abigail, I have fought here three long years to bend these stiff-necked people to me, and now, just now when some good respect is rising for me in the parish, you compromise my very character. I have given you a home, child, I have put clothes upon your back- now give me upright answer. Your name in the town- it is entirely white, is it not? This quote proves that once Parris’s authority started to increase, Abigail, his niece had to start trouble, causing many people to look at Parris differently and, causing his power in the society to decrease. Reputation led the Crucible’s many characters to resort to various actions and lies to retain their own character. The pressure of society put forth on the characters, caused a chain reaction of lie and deceit that caused the death of many people. The screenplay the Crucible, was therefore wrought with the theme of reputation as a leading factor in the development of the plotline and story.

Kofi Annan Leadership Traits

The Five Virtues of Kofi Annan: Case Study Having sat at the helm of the United Nations for two terms, Kofi Annan exhibited astute and strong leadership skills. Admiration for his ability to bring different warring parties together was unending. He always wished for a world where sufferance of innocent global citizens would end. Among the virtues he stand out to have entrenched in his leadership is dignity.Advertising We will write a custom case study sample on Kofi Annan Leadership Traits specifically for you for only $16.05 $11/page Learn More He always believed that all people regardless of their social-economic status, nationality, race and other lines of segregation would have a dignified life. Indeed, the life that Annan envisaged for all people was free of atrocities, poverty and pandemics such as Aids. Ciulla (2003) postulates that he always saw both sides of the coin in that he could negotiate with perceived criminals such as Saddam Hussein for the sake of innocent civilians who in many instances were caught in the crossfire. To him, dignity was a major virtue of leadership. Second, throughout his mission as the Secretary General to the UN, he never fell short of confidence in all his actions and attitude. Despite taking positions that put him at loggerheads with major world leaders like Madeleine Albright, Annan had confidence that his cause of action was the best in delivering peace to the world. Third, Annan held courage as an important virtue that all leaders should learn. He never feared to enhance access to medical care, food and other humanitarian assistance regardless of the risks and dangers this action predisposed him to. Fourth, Annan values compassion, which is a major aspect of transformative and supportive leadership. He never shied away from the poor and the meek. Indeed, Ciulla (2003) pinpoints an instance where he randomly got out of his motorcade and spent over an hour with a refugee who had fled war in I raq. Finally, Annan always preached faith. He believed that all leaders should have faith in their actions whenever their actions would end up bringing peace to the world. Standpoints Held by Different Critical Thinkers Ruth Benedict The major concept of her works revolves around explaining anthropology and the way it affects normalcy of different people especially those holding leadership positions in organizations and groups. She articulates that leadership is nurtured and can be uniform across the entire world despite different social, religious, racial and national backgrounds. Leaders should be consistent in their actions regardless of the contexts they encounter. To that end, Benedict says that all leaders are able to differentiate between right and wrong and inspire followership that brings about happiness to all people. Mary Midgley She concentrates her main ideas on themes of leadership by articulating that a leader should be ready to try out ‘his/her sword’ . By that, she means that every leader has special attributes, which he/she should use to achieve the goals that the followers. It is important to note that Midgley holds the view that different leaders are unique and their leadership skills are dependent on the goals they seek to accomplish. It is therefore upon the leaders to understand their ‘swords’ and act in a way that can provide the best form of leadership to their organizations. F.G Bailey Bailey emphasizes on values and beliefs in leadership. He asserts that virtuous leaders should be able to make decisions that do not contradict the beliefs of the followers. Beliefs and values should shape the common goal in a group. No leaders should exert their personal beliefs and values to the followers. UN Commission on Human Rights The global body focuses its attention and activities on the need to uphold human rights regardless of where people live. UNCHR emphasizes on the importance of human dignity and the need t o remove impediments that lead to violation of human rights. In many instances, UNCHR has spearheaded democratic leadership and governance where governments enshrine human rights as a way of dignifying the lives of their citizens. Indeed, the organization holds the view that all human beings are important regardless of their location in the world and governments should abide by global standards in enshrining human rights. Isaiah Berlin Berlin asserts that leaders face numerous challenges and upheavals in pursuit of ideal societies and organizations. These challenges hinder their ability to perform nobly although they provide different insights to the leaders. To him, leadership should entail the ability of leaders to overcome such hurdles and achieve their objectives in line with the wishes and aspirations of the followers. In pursuit of idealistic leadership, Berlin articulates that leaders and organizations should be able to differentiate actions that could impede the achievemen t of the goals that are in the best interest of the majority. Application of the Theoretical Standpoints on the Case Study From the above case study, we learn of a global icon who exercised leadership using virtues. Annan was global leader despite his roots being in Africa. He always perceived the world from the lens of globalization and nobleness. Benedict cite him as an example of a leader who defied social and economic backgrounds to achieve his objective of uniting the world and delivering peace to war-torn regions.Advertising Looking for case study on political sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More His virtues were consistent throughout his life as the UN Secretary General. Despite many setbacks that impeded his ability to achieve some of his goals, Annan represents a leader whose ‘anthropology’ did not lead to ‘abnormal’ leadership style (Ciulla, 2003). Since his school days, Ciulla (2003) asserts that Annan was able to nurture his astuteness as a leader and adopt virtues that are important in enhancing effective leadership. His virtues of dignity, confidence, courage, compassion and faith stuck with him throughout his reign at the UN. As elucidated by Benedict, Annan depicts a leader who has the ability to distinguish between right and wrong and inspire followership that brings about happiness to all people. Midgley on the other hand would attribute the leadership abilities of Annan to uniqueness of specific leaders. She pinpoints that leaders have ‘their own swords’, which they use to exercise leadership. To her, Kofi Annan was a unique leader whose traits and virtues were outstanding. To cement her assertions, it is important to highlight that his predecessor and successor have different traits. Indeed, they have ‘different swords’ to exercise leadership. Midgley tends to disagree that leadership is nurtured and asserts that it is inborn a nd not all leaders are able to exercise leadership qualities in a similar way. The aspirations and objectives of UNCHR seem to coincide with the virtues of leadership offered by Annan. In particular, UNCHCR emphasizes on the need for human dignity in the world. This would imply that leaders work towards ending atrocities, poverty, diseases and wars that demean and devalue human dignity. Annan’s virtues dictated that all human beings should live in a peaceful and loving way and instances of wars ought to end (Ciulla, 2003). In fact, Annan pointed out that no government should shield itself in the name of sovereignty given the fact that its citizens have suffered in a huge way. To this end, he called for other nations to bear the responsibility and obligation to prevent atrocities that occur in some countries. This way, Annan was convinced that the world would uphold human dignity, importance of peace and the need to reduce pandemics.Advertising We will write a custom case study sample on Kofi Annan Leadership Traits specifically for you for only $16.05 $11/page Learn More Berlin perceives Annan from a standpoint of idealism. He sees his leadership style to draw inspiration from his virtues as too optimistic for the world to achieve. While Annan believes that world peace is possible, Berlin tends to be cautious by saying that there are many challenges for leadership that pursues idealism. Nonetheless, Berlin sees such leadership being very important since it helps leaders to address similar situations in future. In essence, the objectives that UNCHR has seem to explain the case study in a more elaborate way than the rest of the theories. This is partly because Annan was the custodian of these objectives when serving as the Secretary General of the UN. To this end, his goals and perception of the global society were motivated by the need to uphold human dignity and peace. His articulation that no country could shield itself in the pretext of sovereignty provided a clear indication of the levels that he could reach in achieving the goals of the organization. Nonetheless, Annan was an outstanding leader whose virtues provided guidance not only to him but also to the international organization that he served. Virtuous leadership brings about effectiveness. All leaders should therefore aspire to have virtues that uphold human dignity. Reference Ciulla, J. (2003). The Ethics of Leadership. New York: Thompson-Wadsworth Publishers.

Cockatiels essays

Cockatiels essays Some of our sore throats are caused by a "strep infection" and this bacteria can be spread to your cockatiel from a sneeze or a cough. A bacterium called E. coli is normally present in our intestines, but it is not a normal resident in the intestines of cockatiels. So be sure that you wash your hands after using the toilet and before handling your cockatiel or its food. Seeds, how do you know if they are alive and nutritious? Sprout them! If less than 75 % of the seeds sprout, they have died and so their nutritional value. Here's how: Place some seeds on a container covered with a paper towel. Soak the seeds with water. Spray seeds daily to keep them moist. The seeds will start to sprout in three or four days. Once they sprout, you can keep them in the refrigerator for up to a week. Rinse them before feeding, as they are very nutritious. The amount of sprouts that can be fed daily are as follows: Lead is the most common poison eaten by caged and wild birds. Sources of lead include: antiques; lead frames of stained-glass windows; Tiffany lamps; weighted items; fishing, scuba, and drapery weights; the foil from champagne and wine bottles; batteries; solder; bullets and air-rifle pellets; old paint; sheetrock; galvanized chicken wire; linoleum; mirror backing; light bulbs bases; dolomite and bone meal products; and leaded gasoline fumes. The Cockatiel was first discovered in Australia in 1770. It did not become popular until the Australian gold rush in the nineteen hundreds. Cookware or drip pans with Teflon or Silverstone. The fumes emitted can kill your Cockatiel. Cockatiels may have allergies. Straining, flatulence (passing of gas), inflammation of the cloaca, or sneezing may be seen. Of course, it is important to rule out the most common causes of these problems, but think about possible allergies the blanket that covers the cage: the sunflower diet? A perfume, household ...

Principles of Human Resource Management - Essay Example This type of appraisal should also provide qualitative and quantitative results as they provide a better understanding. The language used in an excellent performance appraisal should be neutral. Life after retirement can take a better meaning if it is well planned for before retirement. In order to live a happy retirement life it is important lay more emphasis on retirement plans. This planning is important in various ways; for one it eradicates the feeling of uselessness for the retired person. It also enables the retired person to live healthy and feel satisfied in life. During the job due to the constraint associated with work one is not able to indulge in certain hobbies such as travelling, therefore it is important to plan for this after retirement. It also reduces dependency on children who also have there own issues to handle. Many companies have started offering retirement counseling which is important for retirement planning. Companies have come to realize that their workers suffer a lot after their retirement due to lack of awareness. As a result this counseling emphasizes on matters of health both physical and mental which affects most of the retired people. The oncept of comparable worth is a social, economic and political issue which is concerned with gender-related pay scale in the workplaces according to Landy and Conte (223). . It requires that both men and women should be paid the same if they are doing work of comparable value in the same workplace. Though many consider the issue of comparable worth as gender neutral, according to me the social perspective of the issue is based on gender specificity as it focuses more on women payments compared to men payments. As a result it has resulted to the devaluation of work done by women. There are various job incentives which are beneficial to all employees. However some are more preferable than others. For instance some of the

Cell Culture and Proliferations | Experiment

Cell Culture and Proliferations | Experiment To study the cell proliferation of Mouse Y1 adrenocotical cells by using MTT (3-(4, 5-diphenyl tetrazolium bromide) and crystal violet staining methods. INTRODUCTION In general, Cell proliferation means multiplication/Reproduction of cells for increasing cell population in a very short span of time. The assay of cell proliferation is to measure the number of cells which are present in the dividing culture medium. Cell proliferation is controlled by using growth factor (Fetal calf serum), Which normally bind to the surface receptors present on the cell membrane generally regulate the cell signaling molecules, which pass the message to nucleus by help of receptor generally where the transcription factor gets bind to the DNA, makes turn off turn on the protein synthesis mechanism, responsible for cell division. Cell proliferation method is very important for studying various biological factors like bioassay, carcinogenic analysis and other toxicological tests. Generally two metods are used for studying cell proliferation i.e. crystal violet staining method and MTT (3-(4, 5-diphenyl tetrazolium bromide) method, here these methods are used to study ce ll growth in mouse Y1 adrenocotical cells. In crystal violet staining method, the DNA of cells is going to stained by crystal violet which produces a colour intensity that is proportional to the cultured cells(including newly proliferated cells). In this method, the principle involved to calculate the cell proliferation is based on the absorbance taken up by the viable cells in culture at different concentrations after the cells are stained with crystal violet. In MTT (3-(4, 5-diphenyl tetrazolium bromide) method, the assay depends on the amount of MTT taken up by the cells, tetrazolium salt is water soluble which produces yellow colour. The tetrazolium MTT is metabolically reduced by active cells, in presence of dehydrogenase enzymes, producing NADH and NADPH which are reducing equivalents. This results in the formation of purple formazan intracellularly, which is measured by spectrophotometer. MATERIALS METHODS Cell culture: In DMEM (Dulbeccos modification of eagles medium),mouse Y1 adrenocotical cells which were grown on monolayer was removed by using mixture of trypsin and EDTA (0.05% and 0.02% ).The cells are incubated by 5minutes by adding Trypsin/EDTA(7ml).After incubation the flask was removed and tapped gently to separate undetached cells. The contents of the cell are transferred to a universal container for centrifugation at 1000rpm/ 5mins.Supernatant was discarded and medium is added for resuspending the cell pellet. The cell number was estimated by using Haemocytometer counter for 15ml the cell suspension dilution was prepared containing density 1.25X105 cells/ml of suspension. In 96 well plate, 60 wells were filled with 100Â µl cell suspension, in this the remaining outer wells are filled with Phosphate Buffer Solution (PBS) of 200Â µl.Allowed the plate overnight in a gas incubator to settle down the cells. Those cells were treated with Fetal Calf Serum (FCS) of different concentrations vary ing from 0% to20% in universal tubes.12 wells of plate were filled with 200Â µl of different concentrations. These plates were incubated for a period of 24hours. Cells were washed with Phosphate Buffered Solution (PBS) for three times using multichannel micropipette; later media containing various serum concentrations were added. These two 96 well plates were used for crystal violet staining and MTT (3-(4, 5-diphenyl tetrazolium bromide) assay after 72 hours of incubation. Crystal Violet Staining Method: The cells were removed from central 60 wells of 96 well plates and filled with 200Â µl of methanol in a fume cupboard. After 15minutes methanol was removed from the plate and was left to dry in the fume cupboard. Once the plates were dried the cells were stained with 200Â µl of crystal violet. Once the staining is complete after 20minutes the plates were washed with Distilled water for atleast three (3) times and then solubilized the cell layer by using 50Â µl of 10% glacial acetic acid. The plates were then kept for incubation in a gas incubator for thirty minutes after incubation Absorbance of wells was measured at 540nm. MTT STAINING METHOD: The cells present in the central 60 wells of 96 well plate were treated with 20Â µl of MTT (5mg/ml solution in PBS) and was left for 4hours in gas incubator at 370c.After incubation by using multichannel pipette medium was removed and 100Â µl of acid-isopropanol was added in order to dissolve the blue formazan crystals from the cell layer and then it was incubated for 30minutes at room temperature after solubilizing formazan crystals Absorbance was measured at 570nm using plate reader. Calculation: Total No. of cells in 5 square = 21 Average cells present in one square = 4.2 Calculation of cell number: The volume of each square is= 4 X 10-3 The total cell number for 5 square gives the cell = 0.02Â µl No. of cells in 1 ml = 105X104 Number of cells required = 395X104 Volume of suspension required = concentration required/ concentration got = 395X104/105X104 = 3.7619 ml cell suspension to be taken Medium to be taken =30,000Â µl-3.7619Â µl = 29996.23Â µl medium to be taken. DISCUSSION: Here the increase in the absorbance with corresponding to the fetal serum concentrations shows the sign for the cell growth. Ammonium cations bind to negatively charged DNA which in turn gave blue color to the mixture. By using the color intensity, viable cells were estimated by means of haemocytometer. No experiment will produce 100% results. So here also errors occurred due to practical errors. Occurrence of errors might be due to: Washout condition of stained culture cells Improper solubilisation of 10% glacial acetic acid. In MTT method the degradation of MTT gives color to the mixture. This degradation was due to the dehaydrogenases of viable cells. The color intensity is directly proportional to the cell growth. Here also the errors might be occurred due to improper solubilisation of formazan crystals (Butler. 1996), (Javoise. 1998). DIFFERENTIATION OF K562 CELLS TO PLATELETS IN PRESENCE OF PMA: Differentiation of K562 cells to megakaryoctes/platelets Phorbol Myristate Acetate treated and untreated cells were spun down in a bench centrifuge and after resuspended in 1ml PBS (having 1 % Bovine serum albumin). Then by using haemocytometer the cell number was calculated, after diluting the suspension. cytospin was added to 1 ml cell volume which was adjusted to density of 106 cells per ml. In assembled cytospin 200 Â µl at 1000 rpm/3min. After fixing the slide in acetone /methanol(50:50), slide was washed with 0.15 M tris buffered saline .In humid temperature Human cd61 cells were incubated for 2 hrs using TBS slide was washed.with rabbit anti- mouse Ig-G anti body cells incubated for for 30 mins at room temperature and washed with TBS, after washing, cells were incubated with Alkaline phosphate anti-alkaline phosphate complex, this was repeated with Ram and APAP for amplification. They were washed under running tap water after staining with red TR substrate and counter was stained with haemotoxylin. Finally the slide was viewed und er microscope after washing with TBS.PMA is a diester of phorbol and a tumor promoting agent (proc.Natl.Acad.sci.USA Vol.82, pp, 3859-3862, june 1985Medical sciences). PMA initiates the signal transduction by protein kinase C (PKC) enzyme which allows promoting the differentiation of K562 cells.By using CD 61 marker the K562 cells were treated .These CD61gets attached to cell network to work as primary antibodies. In addition with cells performs a seconndary antibobodies whenever exposed to Ram along with APAP and forms pink color by attaching to FC region of anti-human CD 61 antibodies. This phenomenon gives the cells under going differentiation when incubated with PMA (MSc Pharmacology Biotechnology, cell biology laboratory manual/ January 2010) RESULT: The slide treated with Phorbol Myristate acetate (PMA) is in pink colour, whereas the slide which is untreated with Phorbol Myristate acetate (PMA) is in blue colour after staining. The cells when treated with PMA differentiate into Platelets/Megakaryocytes. In PMA the diseter bond promotes the tumor, which in turn activates the signal transduction of protein kinase C enzyme(PKC) inn K562 cells causes the CD61 expression. The RAM IgG gets attached to the CD61 antibodies, these K562 cells when incubated with APAAP form a complex. Later fast red dye was added to the mixture which gets attached to the APAAP, the cells turn pink by taking the stain. The cells containing PMA expressed the CD61. It generates the (signal transduction protein kinase C) PKC enzyme and on of K562 cells causes the expression of CD61. The rabbit antimouse IgG antibodies attach to the antibodies of CD61 when incubated in the presence of APAAP (alkaline phosphatase anti-alkaline phosphatise) on of K562 cells complex. Then we add the fast red dye to the mixture which was attached to APAAP (alkaline phosphatase anti-alkaline phosphatise) and stains the cells pink. CD61 was expressed by only those cells which had PMA (Shelly, 2000)

Women, Sport and Film :: Argumentative Persuasive Essays

Women, Sport and Film Out of all the material we covered in this course, the ones that bear most directly on this question I think are the documentary about women in sports, and the movie "Girlfight". However, I felt that both of these films focussed on the issue from women's point of view. This is not to say that it isn't important or necessary to do so, but I started thinking about how men are also greatly affected by gender stereotyping. Being in a women's college, I feel like we focus a lot on the ways in which women are forced into certain roles, but we neglect to also look at how men are forced into certain roles. Last semester I watched the movie "Billy Elliot", about a young boy growing up in Newcastle, England, during the time of the miner's strike. I think the movie illustrates very well the costs and benefits of breaking gender stereotypes. Billy grows up in a mining family and his family consists of himself, his father, and his elder brother. He is surrounded only by male role models, and that too men who engage in manual labour. His father and his brother are both very "masculine" in the traditional sense of the word. The basic plot of the movie is that Billy wants to be a ballet dancer. His father wants him to learn boxing, but he sees a group of girls having ballet lessons at the same time and he starts taking ballet lessons on the sly. He turns out to be very talented, and his teacher wants him to apply to go to ballet school on a scholarship. The rest of the movie follows his progress and his struggle to be accepted by his family once he's been discovered. At first his father prohib its him from doing ballet, and calls him a "pouf", but Billy persists and is finally accepted by his family and community. I found it interesting that even though Billy is pre-pubescent, the mere fact that he wants to learn ballet induces people to question his sexuality even at such an early age. At an age when children aren't supposed to be sexual beings yet, Billy is under constant pressure to decide what his sexual orientation is, both by his family in that he has to defend himself, and by a friend of his in school who fits a certain stereotype of homosexuality and is romantically interested in him.

First year students’ challenges Essay

Entering a collage is like entering to a new different culture for high school student. Students are not just entering a school, but they are entering an academic environment. Many challenges will be ahead for them since it is the first year of transition. Some students might need one or two semesters to adopt the new environment. The most common challenges that students will face are not only the academic challenge, but also time management and responsibility challenges. Academic challenge is the first difficulty for the freshman students. The academic workload is a lot more that they can think of. Indeed, they are required to read and research more for their homework, assignments, or research papers. For example, students are required to finish one book in one or two week in order to do their do assignment, while other classes also have much homework. Students cannot complain that they have much other homework to do, but they need to finish it one time, instead. Be able to do so, students will need to face another challenge that is time management. Time management will be the second challenge for the first year student as well. As I mentioned above, there are many workload that students need to finish, so student need to have time management. In fact, they need to plan what to do, how much time they need to spend for each of their homework, or they will not be able to finish it one time. For instance, they need to classify their work from urgent and important to important but not urgent. Form my own experience, I managed my work by considering which homework is more urgent then I did it first, and less urgent, I did it later. In addition, students will face the challenge of responsibility. After entering the college, the students will need to be on their owns. They need to have responsible for every activity they do, and every decision they make. They cannot put blame on somebody or something else. To instructor or other people, they are the mature now. If they are wake up late for school, for example, it is their fault, they cannot say because of this or because of that. In conclusion, the first year of transition can be one of the most challenges that they will have in their lives. They need to be more mature, and deal with the challenges they face by themselves.

Burns Essays

Skin Disorders/Burns Essays Skin Disorders/Burns Essay Skin Disorders/Burns Essay The incidence of burn injuries has been declining during the past several decades. Approximately 2 million people require medical attention for burn injury in the United States each year (Kao Garner, 2000). The risk of death increases significantly if the patient has sustained both a cutaneous burn injury and a smoke inhalation injury.Young children and elderly people are at particularly high risk for burn injury. The skin in people in these two age groups is thin and fragile; therefore, even a limited period of contact with a source of heat can create a full-thickness burn. The National Center for Injury Prevention and Control lists â€Å"fire/burn† among the categories of the 1998 Unintentional Injuries and Adverse Effects.Most burn injuries occur in the home, usually in the kitchen while cooking and in the bathroom by means of scalds or improper use of electrical appliances around water sources (Gordon Goodwin, 2001). Careless cooking is one of the leading causes of household fires in the United States. The U.S. Fire Administration reports that nearly one third of all residential fires begin in the kitchen. The major factors contributing to cooking fires include unattended cooking, grease, and combustible materials on the stovetop.Burns can also occur from work-related injuries. Education to prevent burn injuries in the workplace should include safe handling of chemicals and chemical products and increasing awareness of the potential for injuries caused by hot objects and substances. The national Institute for Burn Medicine, which collects statistical data from burn centers throughout the United States, notes that most patients (75%) are victims of their own actions. Contributing to the statistics are scalds in toddlers, school-age children playing with matches, electrical injury in teenage boys, and smoking in adults combined with the use of drugs and alcohol. One of the major culprits of burn injuries is the inappropriate u se of gasoline. The U.S. Home Product Report, 1993-1997 (2001), indicated that there were over 140,000 gasoline-related fires and approximately 500 people died from gasoline-related injuries during this period.Many burns can be prevented. Medical personnel can play an active role in preventing fires and burns by teaching prevention concepts and promoting the use of smoke alarms has had the greatest impact on decreasing fire deaths in the United States.There are four major goals relating to burns:PreventionInstitution of lifesaving measures for the severely burned personPrevention of disability and disfigurement through early, specialized, individualized treatmentRehabilitation through reconstructive surgery and rehabilitative programsII. DiscussionA. Classification of BurnsBurn injuries are described according to the depth of the injury and the extent of body surface area injured.a.)  Ã‚  Ã‚   Burn DepthBurns are classified according to the depth of tissue destruction as superfici al partial-thickness injuries, deep partial-thickness injuries, or full-thickness injuries. Burn depth determines whether epithelialization will occur. Determining burn depth can be difficult even for the experienced burn care provider.In a superficial partial-thickness burn, the epidermis is destroyed or injured and a portion of the dermis may be injured. The damaged skin may be painful and appear red and dry, as in sunburn, or it may blister.A deep partial-thickness burn involves destruction of the epidermis and upper layers of the dermis and injury to deeper portions of the dermis. The wound is painful, appears red, and exudes fluid. Capillary refill follows tissue blanching. Hair follicles remain intact. Deep partial-thickness burns take longer to heal and are more likely to result in hypertrophic scars.A full-thickness burn involves total destruction of epidermis and dermis and, in some cases, underlying tissue as well. Wound color ranges widely from white to red, brown, or bla ck. The burned are is painless because nerve fibers are destroyed. The wound appears leathery; hair follicles and sweat glands are destroyed.The following factors are considered in determining the depth of the burn: ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   How the injury occurred ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Causative agent, such as flame, or scalding liquid ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Temperature of the burning agent ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Duration of contact with the agent ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Thickness of the skinB. Management of the Patient with a Burn InjuryBurn care must be planned according to the burn depth and local response, the extent of the injury, and the presence of a systematic response. Burn care then proceeds through three phases: emergent/resuscitative phase, acute/intermediate phase, and rehabilitation phase. Although priorities exist for each of the phases, the phases overlap, and assessment and management of specific problem s and complications are not limited to these phases but take place throughout burn care.C. Planning and GoalsThe major goals for the patient may include restoration of normal fluid balance, absence of infection, attainment of anabolic state and normal weight, improved skin integrity, reduction of pain and discomfort, optimal physical mobility, adequate patient and family coping, adequate patient and family knowledge of burn treatment, and absence of complications. Achieving these goals requires a collaborative, interdisciplinary approach to patient management.III. ConclusionContinued assessment of the burn patient during the early weeks after the burn injury-focuses in hemodynamic alterations, wound healing, pain and psychosocial responses, and early detection of complications.Other significant and ongoing assessment focus on pain and psychosocial responses, daily body weights, caloric intake, general hydration, and serum electrolyte, hemoglobin, and hematocrit levels. Assessment fo r excessive bleeding from blood vessels adjacent to areas of surgical exploration and debridement is necessary as well.

Kinds of child abuses Essays

Kinds of child abuses Essays Kinds of child abuses Essay Kinds of child abuses Essay Emotional maltreatment happens when a parent is shouting, disregarding, rejecting, and insulating the kid doing them feel like they are non deserving anything and follow what they are asked to make so they do nt acquire in problem. When a parent ignores their kid they do nt react to the kid or even look at them and it happens when they are inquiring inquiries or what to cognize about something it merely seems like they are non at that place. Rejecting a kid is when the parent feels like they do nt hold a kid and does nt what to be around them because they feel like they are nil and merely wants to walk ever from them. Isolating a kid it s like holding their kid off from nature and non being around anyone because they feel like they should nt hold the freedom to make anything or speak to others. There are many marks of emotional maltreatment but the of import 1s are that a kid falls in depression, go aggressive, loss of appetency, and be apathetic significance they do nt care about wh at s traveling about in their universe. Emotional maltreatment happens because the parent of the kid does nt cognize how to react in a good behaviour without doing their kid afraid of what they might state them. Besides parents might hold had went through some sort of emotional abuse some clip in their life and feel they should move the same with their ain kid. The most of import thing a parent should make is quiet down and talk in a quiet voice that wo nt do the kid feel un safe and show that they love them. Child disregard is really common in the United States and happens anyplace in the universe. Disregard is when a parent does nt give their kid the basic needs they need. Some of these demands are vesture, nutrient, instruction, and many more. This happens more when a parent does nt care about the demands of their kid and besides lives in a place where there is a low income or do nt hold a occupation where they can offer a kid with the demands the demand. Some marks of disregard are when a kid is ever hungry because they do nt hold anything to eat, when they are ever have oning the same apparels and look dirty because they do nt rinse themselves, besides when they do nt desire to be at place at any clip because they feel like they are non deserving anything. A parent should ever be cognizant of the demands of their kid so they feel they are loved and are ever willing to give them the best. Physical maltreatment is a immense trade because it s against the jurisprudence to ache a kid go forthing them with contusions, Burnss, broken castanetss, and any other sort of break that a kid can acquire from the parent. Physical maltreatment frequently happens when a parent becomes angry without the kid holding nil to make with it because of emphasis, choler, and depression. Children that are physically abuse become aggressive, have low ego regard, bad behaviour, do nt make good in school, and ca nt be around others. When a kid goes through physical maltreatment they act really different so they use to make because they do nt cognize what to make with their life s and leads to suicide because they do nt happen a solution to what they are traveling through and most of import they do nt speak about with person about it so they can a manner to work out the job without harming themselves. Finally there is sexual maltreatment which is something that I do nt understand a parent would make to their ain kid it merely seems truly unnatural to make to a kid but it is really normal and happens in any sort of household without holding anyone cognizing about it. Sexual maltreatment happens in the same place where they live and ends up being the parent sexually mistreating them. Sexual maltreatment starts by merely touching them doing them experience safe and ends up mistreating them in different ways and leads to holding sex with them for many old ages. When this happens kids go really insecure being around others and do nt desire anyone to touch them because they feel like something bad will go on to them and go fearful. In decision with all these sorts of kid maltreatments there are out in our universe we should take really good attention of our kids because they are the visible radiation of our life s they deserve to populate in a safe universe where everything is peace and no injury to them. There are many things we as parents can make so these things do nt go on to our kids. The most of import one is ask for aid and happen a solution so it does nt stop up aching our kids and demoing them our love and attention for them. Besides if a kid is traveling to through any sort of maltreatment they should happen aid and speak about what they are traveling through so things can acquire better and non do it worse than it a already is. Never be afraid of making the right thing because no 1 non even your ain household can harm you doing you experience insecure. Children should neer maintain an maltreatment to themselves whoever is harming them should hold to travel to imprison for making something they should nt of done to a kid. In my ain words and what I think about maltreatment is that a kid should neer be maltreatment for no ground because they are kids and the lone thing they need is love to go better individuals in life `and non populate with something that will ever be at that place for life.

Assigment Research Paper Example | Topics and Well Written Essays - 1000 words

Assigment - Research Paper Example e description of afterlife in his book â€Å"The Divine Comedy† wherein he elaborated the context of hell (inferno), purgatory (purgatorio) and heaven (paradise). Anyone of the right mind, when made to choose amongst the three, will certainly desire to end up in heaven or for some with conscious guilt of sins committed, it will be the purgatory but never the detrimental underworld. Alighieri illustrated nine circles of hell where the first five imprison those who committed egocentric sins, the sixth and seventh for those with violent sins, and the last two which are considered as the worst are for those with malicious sins. Evolution of culture through centuries made people contest the timelessness of Alighieri’s hierarchy of misdemeanor. Such as how murder became less evil against pertinacious actions of the hypocrites or how blasphemy is on a lower circle than heresy when both profess destructive testimony against God. In this paper, an attempt to realign the hierarchy according to personal visualization of hell had been made while taking into account the annotations made by Alighieri. Reorganizing a systematize diagram is a challenging task as one could believe that it is indeed a seamless creation. I considered the seven deadly sins as published in the Bible and deemed the inclusion of Pride and Envy as sins worthy of being punished in hell. Electing a sin to be eliminated from this hierarchy is not an option yet collation of sins that I contemplated as parallel has been my alternative. The first circle would captivate the people who lived with pride and disregarded humility. They are those who took greater regard of themselves rather that humble recognizing these gifts and sharing it to those in need. As the beatitude says â€Å"Beati pauperes spiritu (Canto XII)†, we are called to act in humbleness not in smugness for whatever we have is the work of a Greater Power and not merely of ourselves. I include the hypocrites in this circle for I see them as too

American life between the years 1919-1929 Essay Example | Topics and Well Written Essays - 750 words

American life between the years 1919-1929 - Essay Example Besides, there were hysterical fears regarding the red Russia, which were attributed to the influence caused by Bolshevik revolution that had occurred earlier in 1917; in fact, this paper will focus on exploring significant issues concerning life between the years 1919 to 1929. During this period, there was anxiety heightened by epidemic attack, which had convulsed the America at the end of the war; in fact, some people had a belief that there were labor tribulations fomented by Bolsheviks. Moreover, this led to campaigns against people who were suspected of having relations with radicals that had been deported to Russia due to cases of Wall Street bombing that led to death of thirty eight people (Aboukhadijeh 1). Furthermore, it was during the same period that a number of state legislature was passed, which involved laws on criminal syndicalism. Besides, this prohibited advocacy of violence in the effort to securing social change, through use of words to achieve the same were not cr iminalized. Conservative businesspeople abolished their association with unions, thereby leading to a reflection of cases referred to as â€Å"judicial lynching.† These cases led to conviction of people such as Nicola Sacco and Bartolomeo Vanzetti; in fact, this case involved prejudice by the judge against the defendant due to the mere fact that they were foreigners from Italy, however, this led to rallies made by liberal radicals, and this led to their execution (Aboukhadijeh 1). It was during the same period that America saw the spawning of Ku Klux Klan after the reaction of the war aftermath; in fact, this was seriously spread during the 1920s (Aboukhadijeh 1). Moreover, this was related to notions against Catholics, Jews, Pacifist, Communist, birth-control, evolution, and internationalist; thus, Klan was spreading vigorously to the Midwest of south peak in the mod 1920s, thereby affecting more than five million American citizens. Later in 1920s, there were efforts, made b y some American to end this movement through the congressional investigation after a stern warning. This period was also faced with increased number of immigrants, who entered and settled in the country; in fact there approximately eight hundred thousand, whereby two-third came from southern and eastern part of Europe. On the other hand, it was during the same period, the Congress focused in ending the breach with Emergency Quota Act of 1921, whereby immigrants from Europe were constrained in duration of year based on the quota (Aboukhadijeh 1). Later in 1924, there was a replacement of the Immigration Act with a stopgap legislation that had been formulated in 1921. In fact, this led to reduction of the three to two percent of the national origins for those who migrated. Apparently, there were prohibitions against immigrants from Japan, since America was not allies with this country; in fact, others in this list included Canadians and Latin Americans. Therefore, the immigration act in 1924 was the end of the immigration that has been unrestricted; thus, by this moment America has turned into country with numerous ethnic communities. There were efforts aimed at organizing the labor unions but they were all in vain due to ethnic difference, which led discrimination based on social class and political solidarity. During this period, there were progressive reforms aimed at prohibiting the support for crusading churches and women, due to Eighteenth Amendment in 1919 (Aboukhadijeh 1).

Higher Education Essay Example | Topics and Well Written Essays - 1000 words

Higher Education - Essay Example transferring knowledge, skills and cultural values to the students, higher education teachers are indirectly keeping young and unemployed individuals off the streets (Stephens & Leach, 1998, p. 203). In general, each of the school teacher(s) have different set of multiple roles which they need to satisfy on a daily basis. Because of their unique function within an educational institution, functionalists may sometimes conclude that the presence of certain school policies and institutions can be dysfunctional for most of the teachers within a given educational institution. As explained by Appelrouth and Edles (2008, p. 386), the occurrence of dysfunctionality is possible because â€Å"they are functional for a more powerful social group or the social system itself†. Functionalists strongly suggest that the main function of higher education teachers is to provide better occupational opportunities for the unemployed students in the long-run. Upon analyzing the functionalist theory of education, it is the students who function as the receiver of the transferred knowledge, skills and cultural values from the school teachers. However, this theory is not applicable when it comes to analyzing the relationship between teachers and students in higher education. Conflict Theory Conflict theory view education as something that â€Å"reflects other inequalities within a given society† (Andersen & Taylor, 2011, p. 348). Because of the presence of racial, class and gender discrimination, not all students are able to receive equal rights to education. Furthermore, conflict perspective in higher education also suggest that the process of tracking down teachers’ ability to deliver good quality teaching based on the prescribed school curriculum also contributes to the development of... This essay stresses that based on symbolic interaction theory, social interaction between teachers and students within an educational institution is possible and necessary when it comes to individual and group successes. As compared to functionalist theory, symbolic interaction theory view human beings within a given society as something that is â€Å"not an established structure but as individuals who are trying to meet their life conditions and expectations†. Based on the core perspectives in contemporary sociological theory, the concept of a structural functionalism is more on the non-rational collective side whereas the orientation of symbolic interaction theory is more on non-rational and individualistic side. Considering the fact that symbolic interaction theory heavily relies on the actions made by the school teachers and students, this particular theory can be more effective and applicable in terms of analyzing how the relationship between the school teachers and stude nts in higher education work. This report makes a conclusion that as compared to functionalist and conflict theories, symbolic interactionism theory is the best applicable theory when it comes to analyzing the relationship between teachers and students in higher education. Unlike the functionalist and conflict theories in sociology, symbolic interactionism theory does not focus on analyzing the structure or functionality or conflicts in a given educational institution but only with regards to how each of the stakeholders who are trying to meet their life conditions and expectations as human beings.

Traditional Art vs Digital Art Essay Example for Free

Traditional Art vs Digital Art Essay Traditional art VS Digital art Fri, May 15, 2009 News Because we live in a century dominated by technology innovation, art itself has been offered new creative horizons. But these new advantages have not been considered so beneficial for the art by some conservative art lovers, who believe that if the art is not created using traditional tools (pen, oils, watercolor, etc. ) that art cannot be considered true art (true in the meaning of recognizing it’s real values). Even if the painting, the design or the sketch is created using   traditional tools, just a pencil and paper, or a drawing tablet, both reflect in the same way the artist’s creative effort and talent. ? What is really offending nowadays, due to this technology, is that many people pretend to have â€Å"become artists† just because he/she can easily combine some Photoshop brushes. The main question that stands is: how much of that person’s talent is reflected in that resulting piece of art? That depends very much on the person behind the technology. If the person who wants to create ART using the computer is an ARTIST, the resulting piece of digital stuff is ART, without the artist, drawing and manipulating programs can’t do a thing.? Sometimes it’ very hard to discern between the real artists and the ones who are just playing with the tools provided by digital programs. There are also some artists, who pretend their art is totally innovative, abstract or exceeds the limits of imagination by disposing mixtures of abstract elements and finally call it ART. The limits of deciding are actually fragile, because everything that is considered to be ART is decided to be valuable, innovative or absolutely worthless, by   subjective points of view, and a design that is considered to be total crap for one might look absolutely amazing in some others’ opinion. That’s true concerning all kinds of tastes. ?To that, many artists are still attached to those sensitive feelings that traditional art gives, that intimacy between yourself and the blank paper, that process of transforming the paper in front of your eyes, touching it, etting dirty or wrapping it when everything goes wrong. These are feelings that cannot be experienced in front of a monitor.? But although modern art is made of true and false artists, talented and crooks, innovative or copy cats, we cannot ignore the BENEFITS that digital technology has brought.? Digital art is also considered the art of the future, because it provides infinite opportunities for the artist to expand his imagination and show us the   crazy and amazing things he can do just by using a mouse, a drawing tablet and his skills. These things can be considered wrong and â€Å"evil† only by those artists who have been painting all their life in the traditional old style and cannot accept or cannot adapt to new techniques.? Digital art can be considered innovating also for the classical process approach:   programs like Adobe Photoshop, Illustrator, After Effect, not to speak about the 3d ones, 3D Studio Max and Maya offers the artist many electronic brushes, pen tools, endless colors and combination, which make their life and the process of creation much easier and pleasant. Amazing   illustrations   and images that seemed impossible to create in the past, are possible with the help of new technologies. The progress that digital artist are achieving nowadays   in the fantasy/sci-fi field is mind blowing. Even though, there are also charcoal nudes or portraits who carry along profound aesthetic emotions for the viewer.? People may say that when an artist creates a   digital piece of art, that piece of art can be printed or sold in various forms in an infinite number of identical copies, and in the same time, that element which is so important for visual art lovers is lost: the uniqueness. But let’s keep in mind that copies of many famous traditional paintings have been manually created by the painters themselves, in order to satisfy as many collectors as possible.? Probably in the future, digital art will be considered traditional as well. But today, it’s the artists’ decision to choose the ways of expression f or their talent. http://blog. tshirt-factory. com/? p=678

Effects of BackGround Music on Phonological Short-Term Memory Essay

Improving recall has been the goal of many scientific studies (Higbee, 2001; Lachman, Weaver, Bandura, Elliot, & Lewkowicz, 1992). As a result, a debate surfaced on the best method to achieve this goal. This study chose to focus on only two methods, emotional state and emotionally arousing words. One’s emotional state or mood is important to consider when exploring memory, because mood affects one’s recall of information (Happiness-Levine & Burgess, 1997; Thaut & l’Etoile, 1993). Music, depending on the type, can help induce or change one’s mood (Rickard, 2012). This is important because, music is apart of many of people’s daily lives. Students, especially, listen to music while they study a task that relies on one’s memory. Beyond just exploring mood, this study wanted to look at what type of word is best remembered. Previous research (Doerksen & Shimamura, 2001; LaBar & Phelps, 1998; Zimmerman & Kelley, 2010) found that people tend to recal l and remember emotional words better than neutral non-emotional words. Building upon these findings is important because, if certain types of words were confirmed as inherently memorable then these words would be powerful. They could be used as powerful tools for writing memorable speeches, lectures, and advertisements. One’s mood working in conjunction with emotional words, could lead to effortless increase in one’s own ability to recall information A recent study by Ferguson and Sheldon (2013) looked at inducing positive emotional states in their participants using classical music. In their study, participants listened to either 12 minutes of an upbeat â€Å"hedonically positive† classical music piece or a slow â€Å"hedonically ambiguous† classical music piece. Their results showed that participant... ...ompany. LaBar, K. S., & Phelps, E. A. (1998). Arousal-mediated memory consolidation: Role of the medial temporal lobe in humans.

Learning and Physical Activity Essay

Explain why physical activity is important to the short and long term health and well being of children. physical activity should be part of every childs life. it promotes living a healthy lifestyle and also the childs general well being. short term health- physical activity promotes a lot of different areas, some of these being; building muscle- helps children move more freely which makes them really enjoy physical play. developing heart and lung functions developing a skeletal frame- if a skeletal frame is not developed properly it cause be a risk of many health problems. Long term health- physical activity is very important and also plays a very big role in preventing obesity. aspects of development 1. 2 explain the development of movement skills in young children and how these skills affect other aspect of development movement skills hand eye coordination- is very important as we need eyes and hands to work together. for example to catch a ball requires the eyes to tell the brain that the hand need to move in order to catch the ball. foot eye coordination- to kick a ball the eyes need to tell the brain tht the foot needs to move in order to kick a ball. Travelling movement- where the child moves from one place to another for example running, skipping and jumping object control movement- objects being send, recieved and travelled with for example. throwing a ball. balance and coodination control gross motor control- this mean whole limb movements, such as moving arms, legs or the entire body(running, jumping) fine motor control- these are smaller actions such as picking up an object using finger or thumb or using your tounge and lips to taste. 2. 3 explain the importance of natural outdoor enviroments for young childrens physical activity and movement skills. As well as playing indoors children should be encouraged to join in in outdoor play. outdoor play is important for mental, emotional and emotional well being. playing outdoors will develop a childs imagination and self confidence. They will get to experience movement and freedom and develop their muscle strength, coordination and problem solving skills. there are alot of benefits of outdoor space, some of these being; playing outside also makes children gain more physical skills because they are learning to use their bodies in a different way to what they would do indoors. Social interaction also goes on whilst playing outside this is because they are not getting as much direction of the adults. children get to learn by using their outside voicesm yelling and running. children learn what is acceptable in one setting that may not be acceptable in another playing outdoors teaches children about different types of textures, smells and sounds outdoor play encourages children to take risks, have more imagination and to explore their own interests. Explain how the plan; meets the individul movement skills needs of children  includes activities that promote competence in movement skills encourages physical play in my plan i planned to do sticky kids with the children at the nursery. sticky kids is physical play so the activity encourages children to participate in physical play. As sticky kids is alot of dancing this helps children develop more of their movement skills. When I planned to do sticky kids, I tried to fit the plan around every childs individual movement skills. The children participated really well and the plan I did went well. There were a few children that wasn’t joining in but we got them all to join in and they participated really well. My plan encouraged physical play because we got the children to get up and join in the activity but they had the chance not too. 4. 1 explain the importance of building physical activity into everyday routines. physical activity is a very important part of every childs life and should be in all their everyday routines. physical activity and exercise will increase a childs strenght and stamina which will then improve their muscle tone and muscle usage. It helps with balance and flexibility in a child and also helps develop catching and throwing skills, movivation and social skills, boosts energy, helps stop anxiety and strees, improves coordination, improves bone strength and heart and lung capacity and has a positive affect on a childs self esteem. physical activity and movement also helps to stimulate the brain which is why it is important for children to have physical activitys in their everyday routines. It is also important for a child to have physcial activity in their everyday routines because it has a big impact on the childrens behaviour. For exmaple if children are running inside instead of telling them no you could say we have to use our walking feet inside but we can run when we go to play outside. Children wont learn as well if they don’t get time outside especially boys this is because boys have a bigger body mass and they need more oxygen than girls. Children need oxygen to learn effectively. Boys also need to get out more because they are more active than girls are.

Women in Leadership Roles

This report examines the research on gender equity in educational leadership published since 1997until 2010. Even though women attaining jobs in school leadership has increased, women still do not fill administrative positions in comparison to men. The majority of research related to women and leadership examines the barriers women face in entering or moving up in the leadership hierarchy. Looking at the differences and similarities in how men and women take on and exercise leadership roles, the authors of the articles suggest ideas based on biological, psychological and sociological theories that stress gender difference. The article, â€Å"Re-thinking educational leadership: exploring the impact of cultural and belief systems† written by Shah, discusses how education and educational leadership theories and practices are influenced by culture and belief systems; with a focus on gender in Muslim societies. The first priority of Muslim women was to look after their family; therefore, before taking on any professional responsibility they had to ensure that no decisions or actions brought shame to their family or extended families. According to Shah, the Muslim women who participated in leadership positions often felt powerless because their decisions and actions were regularly scrutinized by men. The second article, â€Å"Gender Differences Among New Recruits to School Administration: Cautionary Footnotes to an Optimistic Tale† written by Riehl and Byrd discusses the factors affecting leadership among men and women in elementary and secondary education. Even though the women were as highly educated as the men, the men often were given many more opportunities. Women were still seen as displaying nurturing characteristics in their leadership style. The article also discusses women’s leadership aspirations to that of their male counterparts. The third article, â€Å"School leadership, sex and gender: welcome to difference† written by Kruger brings into light the biological differences in genetic make up of men and women. It discusses how different hormones and brain structure are the reasons for differences in behaviour and personality among men and women, which is considered a deciding factor in their leadership styles. Kruger also examines how the environment plays an important role in the realization of gender differences in leadership. The last article, â€Å"Gender and educational Leadership in England: a comparison of secondary headteachers’ views over time† written by Coleman discusses the expectations of women and men as principals in England in the 1990`s and in 2004. The article focuses on women with regards to work and personal life. Coleman reports that women have larger roles at work and at home, whereas men generally concern themselves with work only. Notably, women were seen as inferior so they adopted male work ethics. The results of Coleman’s studies are similar to those in other countries. It was very interesting to review the articles I chose to better understand the ways that educational leadership is perceived with respect to gender in the education system. As I continued to review the research, I thought it was of importance to examine the differing leadership styles and barriers, along with the similarities women faced in both western and non-western cultures. Throughout this inquiry I will cite several reasons for the low proportion of women as educational leaders. According to Shah, â€Å"Men and women are conceptually divided into two separate worlds. Home is defined as a woman’s legitimate ideological and physical space, while a man dominates the world outside the home† (p. 31). With the ever-changing society, Muslim women started exploring their options and took more of an active role outside the home. Interestingly, the women who attained positions of leadership worked in the women-only establishments. It was troublesome for a woman to work in a mixed gender environment because their educational decisions went through a male counterpart, regardless of their seniority. Women still held strong beliefs and values with respect to education; similar to western cultures, but the notion of women in a male dominated hierarchy was still considered problematic. I strongly believe that family and home responsibilities are still more likely to affect the career paths of women than of men today as they pursue administrative positions. Riehl and Byrd also believe that gender plays a major factor in the career development process to the degree that men and women encounter different circumstances, act differently, and/or experience different outcomes. The theoretical explanations that have emerged are as follows: women have not been socialized to aspire to administrative roles or to prepare for them, higher level jobs were designed to exclude women and school leadership is located in male dominance in society overall, not just educational (p. 46). I believe society as a whole is more accepting of these barriers now; however, these issues are still evident, but not as strong. Similar to today, women as teachers and principals were more likely to be found at the elementary level and men at the secondary level. While I do see many women teaching as previously mentioned, it was interesting to hear that men at their level receive more administrative practice, thus leading to senior administrative positions. Also, the amount of education one received didn’t play a huge factor in the hiring process. According to Riel and Bryd even the objective factors such as â€Å"obtaining education or experience increased women’s chances of becoming administrators, they did not bring women’s chances to parity with men’s† (p. 61). Kruger also examines gender differences but relates it to the biological sex differences in school leadership. Women by nature have a more caring, nurturing personality and this influences their administrative styles in a male dominant society. Kruger found that: â€Å"women are stronger educational leaders than their male colleagues. They carry out more educational activities and spend more time on educational matters than men. Women are more focused on instruction and education, on the school goals, they are higher on creating a positive culture and an orderly learning atmosphere, they have a stronger classroom orientation, they reward teachers more often and they create more professional development opportunities for teachers† (p. 62). It appears as though women are strong educational leaders; however, we have learned throughout this course that male and female styles tend to differ even when they occupy the same leadership role. Women, who already face enough resistance and obstacles in a male dominated field, find their leadership styles are judged more harshly by men; however thi s is not the same for the men. According to Kruger, â€Å"Women who display male leadership styles are more negatively judged compared with those who do not, but men with a female leadership style do not seem to be more negatively judged† (p. 164). Despite these factors more women tend to work under male principals then they do women. The reason for this is perhaps do to personality conflicts they may have with the same sexes on ideas of what successful administration entails. Another deciding factor in this is that women tend to be more education rooted and become administrators because out of their desire to improve education, whereas men take on administer roles mainly for the salary. Coleman’s research states that the stereotypical leader is a white, heterosexual, middle class male; therefore, women are often viewed as outsiders in a position of leadership. Coleman identifies various factors effecting women’s likelihood of becoming leaders such as â€Å"discrimination, lack of confidence, hesitation in making career plans, stereotyped into ‘caring’ pastoral roles that were then not seen as fitting them for leadership and there were multiple difficulties for women in combining a family and career† (p. 385). Women’s leadership styles were seen as passive and gentle, while men were stronger and more decisive. In 2004, only half of the women surveyed report experience in discrimination related to advancements due to the likelihood of being labeled a feminist (Coleman, p. 86). Surprisingly, the traditional male style leadership has given way to more feminine styles of leadership. Males have been seen as putting work first over family at all times, which has influenced women to the point of minimizing maternity leave and foregoing their desire to be supportive figures to younger women. Throughout this course we have discussed various effective educational leadership practices. Leaders should be able to adapt their leadership styles according to the situation. Therefore, change is necessary if we want to move ahead in our respective field. The passive, nurturing, education orientated and productive styles depicted by women in these articles are accepted today by both genders in leadership positions. Noteworthy, a strong dominant leader is not always effective or seen as an acceptable style. As a teacher, I often see different leadership styles and can conclude that men and women at times see things differently. In conclusion, the role of women in educational leadership positions continues to evolve; however, there still needs to be work done in order to ensure equality. If one were to look at our current list of administrators in the school board they would notice that there is significant higher ratio of male to female administrators. The females are often placed in small, rural elementary schools or are the vice-principals of secondary schools. I truly believe women will always face barriers while trying to attain leadership positions; however, if we work together, take charge and voice our opinions things may change in the upcoming years.

Just Deserts vs. Just Desserts

Just Deserts vs. Just Desserts Just Deserts vs. Just Desserts Just Deserts vs. Just Desserts By Maeve Maddox The use of the expression â€Å"just deserts† in a recent DWT exercise brought some reader objections. Here are two: She got her just deserts really? â€Å"Desert†Ã‚  like an arid place? Isnt it desserts? You are surely incorrect. The correct form of the expression is â€Å"just desserts.† Many speakers think that people who get what they deserve get dessert, unaware that there’s another noun pronounced like dessert but spelled with one s: desert [deh-ZERT]. Here are three kinds of desert: desert [DEZ-ert] (noun): an arid place desert [deh-ZERT] (verb): to abandon desert [deh-ZERT] (noun): worthiness of recompense Desert [DEZ-ert] in the sense of a wasteland or wilderness came into English by way of French from Latin  desertum, â€Å"thing abandoned.† Desertum is used in the Latin Vulgate version of the Bible to translate the word for â€Å"wilderness.† Dessert [deh-ZERT] in the sense of the last course of a meal is from French  desservir, â€Å"to clear the table,† literally, â€Å"to un-serve.† The dessert comes at the end of the meal when the table has been cleared of everything that went before. Desert [deh-ZERT] in the sense of consequences comes from French  deservir, â€Å"to be worthy to have,† or â€Å"to deserve,† from Latin  deservire, â€Å"to serve well.† One reader explained why she’s reluctant to accept the correct spelling of the expression: My interpretation of â€Å"just desserts† was that â€Å"dessert† was the sweet stuff at the end of a meal†¦cake, ice cream, etc. So â€Å"just desserts† was you got the dessert you deserved, meaning you didn’t get the sweet stuff or you got something less than sweet. The expression â€Å"Just Desserts† is often used deliberately as a marketing pun for the selling of baked goods, but there are plenty of unintentional errors among the examples that come up in a Web search: In the end she turns on him, but also gets her just desserts when the mob’s lawyer finally sees the light. –The Rotarian (magazine). Woman driver gets her just desserts –Video blog A serial Czech  prankster got his just desserts  after pals spooked him with a hilarious specter stunt.  Ã¢â‚¬â€œNY Daily News The error even appears in books from reputable publishers: He should have been pleased that Ralph Standishhad got his just desserts. –A Parliament of Spies, Cassandra Clark, Minotaur 2012, p. 221. Note: The character Standish is a bad man who has been found murdered. Corrected examples: In the end she turns on him, but also gets her just deserts when the mob’s lawyer finally sees the light. Woman driver gets her just deserts A serial Czech  prankster got his just deserts  after pals spooked him with a hilarious specter stunt.   He should have been pleased that Ralph Standishhad got his just deserts. Although the expression is most frequently used to refer to a deserved punishment, it can also refer to a deserved reward. For example the following headline from the Oye! Times (Toronto) uses the expression in a positive sense. [The actor mentioned has been honored with a star on the Hollywood Walk of Fame]: CHRISTOPH WALTZ GETS HIS JUST DESSERTS [sic] Bottom line: Ice cream and chocolate cake are desserts. People who get what’s coming to them get their just  deserts. Want to improve your English in five minutes a day? Get a subscription and start receiving our writing tips and exercises daily!
