Roots and Stems free essay sample

Roots, stems, and leaves are the three main components of a plant. They are vital to a plant’s survival, and without them, the plant would die. Each component has a different function and varying appearances. A leaf’s main function in the plant is to produce energy through photosynthesis. They absorb sunlight and create sugar. The leaf then constantly sends energy throughout the stem, roots, and other parts of the plant. Sometimes leaves are also used for protection against animals that are a threat to the plant’s health and survival. They come in different shapes and sizes. Some are smaller and rounder than others, while some are in the shape of needles like a cactus. Leaves are essential in the obtainment of energy for plants. Stems have two primary functions in the plant.

Other functions include storing carbohydrates, nutrients, and water. Rhizomes or underground stems, tubers, and bulbs are different types of stems. A sign of a healthy stem is when the stem is erect because this creates the most support for the plant. Roots are the most important feature for a plant’s health. Functions of the roots include providing anchorage, absorbing water and nutrients, and transporting the water and nutrients throughout the parts of the plant. They tend to grow away from sunlight and towards water in order to obtain the most water possible. Another important job is that they store starch which allows photosynthesis to occur. There are two types of roots: tap roots and fibrous roots. Tap roots are large, and they provide the most anchorage possible while fibrous roots are threadlike, and give the plant the most exposure to water and minerals. There are many different other parts of the plant, but these three are the most important. Without them there would be no plants, and without plants there would be no oxygen for us to breathe. The human race needs the roots, stems, and leaves to continue functioning because if they don’t, we may find ourselves facing extinction.

Free Essays on Mythology

Greek mythology was fully developed by about the 8th century BC. As the Greek people began to realize that the sun, moon and stars followed certain rhythms with The seasons, they thought that something not beast nor human had the power. That is were the idea of gods came in. Ancient Greeks believed that the gods, who resembled Humans lived on Mount Olympus, where they had their own little society. Individual Gods were part of three main parts of the world- the sky or heaven, the sea, and the Earth. The 12 chief gods were Zeus was the god of the sky and ruler of the Olympian gods. He was considered the father of the gods, and of mortals, although he did not create either; he was their father in the sense of being the ruler both of the Olympian gods and of the human race. He was the rain god, and the cloud gatherer, his wepon was the terrible thunderbolt. His breastplate was the aegis, his bird the eagle, his tree the oak. Zeus was the youngest son of the Titans, Cronus and Rhea, and the brother of the Poseidon, Hades, Hestia, Demeter, and Hera. According to one of the ancient myths of the birth of Zeus, Cronus, having heard the prophecy that he might be dethroned by one of his children, swallowed them as they were born. Upon the birth of Zeus, Rhea wrapped a stone in swaddling clothes for Cronus to swallow and concealed the infant god in Crete, where he was fed on the milk of the goat Amalthaea and reared by nymphs. When Zeus grew to maturity, he forced Cronus to regergitate the other children, who were eager to take vengeance on their father. In the war that followed, the Titans fought on the side of Cronus, but Zeus and the other gods were successful, and the Titans were banished to Tartarus.... Free Essays on Mythology Free Essays on Mythology Some of the world’s most compelling relationships have their roots in classical mythology. Many different religions have stories or ideals that have similarities to the relationships seen in ancient Greek mythology. From the interaction of mortals and gods we see how different writers viewed religion, family, and society. More specifically we see how the gods influence the way of life of a mortal. In Homer’s Odyssey there are many instances where the gods help mortals through their struggles. However, at the same time, there are situations when gods use their power to all but destroy the lives of the mortals who have displeased them. One of the most intriguing relationships between god and mortal is that of Athena and Odysseus. There are many times when Athena gives Odysseus the helping hand needed to succeed in his ventures to return to Ithaca. The roles that the gods play in the Homeric world compared with Euripides and Sophocles have great similarities as we ll as differences. Looking at how Athena seems to take care of Odysseus, it seems that the gods, perhaps only Athena, tend to take a liking to mortals occasionally. You could draw the conclusion that Athena seems to like Odysseus’ family. She shows almost as much interest in Telemachos as she does Odysseus. â€Å"Likening herself to Mentor in form and in voice: â€Å"Telemachos, already your well-greaved companions are seated at the oars awaiting your urging. Let us go, so that we may not long delay from the journey.† (Book II, pg 26, lines 401-404) In this passage Athena has taken the form of Mentor, a good companion of Odysseus, and has instructed Telemachos â€Å"to go in a ship onto the murky sea to learn of the return of my father who is gone so long.† (Book II, pg 23, lines 262-263) Athena then says, â€Å"†¦hereafter you will not be a coward or senseless. If there is really instilled in you the good might of your father and you are as he was to achieve... Free Essays on Mythology Greek mythology was fully developed by about the 8th century BC.

Free Essays on Mythology Greek Mythology Greek Mythology, beliefs and ritual observances of the ancient Greeks, who became the first Western civilization about 2000 BC. It consists mainly of a body of diverse stories and legends about a variety of gods. Greek mythology had become fully developed by about the 700s BC. Three classic collections of myths-Theogony by the poet Hesiod and the Iliad and the Odyssey by the poet Homer-appeared at about that time. Greek mythology has several distinguishing characteristics. The Greek gods resembled humans in form and showed human feelings. Unlike ancient religions such as Hinduism or Judaism, Greek mythology did not involve special revelations or spiritual teachings. It also varied widely in practice and belief, with no formal structure, such as a church government, and no written code, such as a sacred book. Principal Gods The Greeks believed that the gods chose Mount Olympus, in a region of Greece called Thessaly, as their home. On Olympus, the gods formed a society that ranked them in terms of authority and powers. However, the gods could roam freely, and individual gods became associated with three main domains-the sky or heaven, the sea, and earth. The 12 chief gods, usually called the Olympians, were Zeus, Hera, Hephaestus, Athena, Apollo, Artemis, Ares, Aphrodite, Hestia, Hermes, Demeter, and Poseidon. Zeus was the head of the gods, and the spiritual father of gods and people. His wife, Hera, was the queen of heaven and the guardian of marriage. Other gods associated with heaven were Hephaestus, god of fire and metalworkers; Athena, goddess of wisdom and war; and Apollo, god of light, poetry, and music. Artemis, goddess of wildlife and the moon; Ares, god of war; and Aphrodite, goddess of love, were other gods of heaven. They were joined by Hestia, goddess of the hearth; and Hermes, messenger of the gods and ruler of science and invention. Poseidon was the ruler of the sea who, with his wife Amphitrite, led a g... Free Essays on Mythology Myths throughout history have been in existence since ancient times and still play a vital role in today’s society. Acting as basis of how to live one’s life and a guide towards beneficial pathways, myths compile many elements into a story that teaches a lesson and/or instills fear in one’s mind to avoid making immoral decisions. Born on the frontier of Ancient Greece philosophy these fictitious accounts of legendary heros and mystical lands were first established into the culture of the Greek way of life. Used to explain the Gods, demigods, and explanations of the universe, myths provide a tangible outlet that the mind is left to ponder. Mysteriously disappearing into the Atlantic Ocean, the island of Atlantis has been the subject matter of its own mythological story for many years. As told by Plato, the story starts when the Gods divided the earth into separate parts, each taking control of their deserved piece.(Hefner, â€Å"Atlantis the Myth†) Poseidon gained control of what was to be Atlantis. Soon after, he fell in love with a mortal women named Cleito with whom he would have ten sons with. He made his first born son the first king of Atlantis and his other sons became princes that would rule separate portions of the island. Saying that Atlantis was prosperous beyond all expectations did not prove to be an understatement. Every citizen was educated, the landscape was made up of green grassy meadows and pristine lakes, and there was not to many conflicts between the inhabitants. New inventions and ideas of how to make life easier came about as they used their intelligence to the fullest extent. I t was what we would call a Utopia. Poseidon set rules and laws that were to be followed by the future rulers and leaders of this fruitful kingdom. As long as the rules and regulations were met the state of the island showed no signs of corruption. However, as time went on and the leaders strayed from the set rules of P...

Modern Times Essay Example | Topics and Well Written Essays - 1000 words

Modern Times - Essay Example Nevertheless, the final film of the series seems to be the most overtly political and inevitably then is the most controversial. Although chock-full of the brand of slapstick, physical humor which has become automatically associated with Chaplin’s acting career, Modern Times is often interpreted to be a representation of Chaplin’s own political affiliations and associations with the Left. However, certain aspects of the film make it quite apparent that Leftist politics hold no monopoly on its figurative content. The aforementioned fans of Chaplin who truly cherish his work cannot help but see through the depictions of poverty and suffering in the film, and see the Tramp urging the Gamin â€Å"to keep smiling†, and to see him relying upon his own values and skills to build a life for himself—ideals that are consistent with capitalism and the American dream. Even before the film starts, any attempt on the part of witch-hunters to tie Chaplin to the Left and condemn Modern Times as hidden socialist propaganda is, all at once, defeated.After the opening credits, superimposed on a clock that symbolizes the tyranny of mechanistic time, the words read: â€Å"‘Modern Times.’ A story of industry, of individual enterprise—humanity crusading in the pursuit of happiness.† Expressing the film’s entire thematic content in only a few brief words, such phrases as â€Å"individual enterprise† and â€Å"pursuit of happiness† give attention not to a Leftist political cause in the context of a Depression

Art - Essay Example Thus, even if they might have been made for different purposes, at least they had similar essences because it is the same Egyptians who were using it as an important sculpture in their society. Khafre Enthroned refers to funerary statue of Pharaoh Khafre who is believed to have ruled Egypt between the years 2520 and 2570. Currently, it is exhibited in the Museum in Cairo, Egypt. It was made using gneiss rock which is closely related to diorite rocks, a valuable, dark extremely hard material that was mined 4000 miles at the royal quarries along the River Nile. The use of such a precious material in the production of this statue was necessary because it equated Khafre’s influences and authority as an Ancient Egyptian Pharaoh. This statue played a very significant role in Egypt: acting as Pharaoh Ka’s sub statue; and as a sign of peace. This explains why it still plays a significant role in the life of the Egyptians today. Great Sphinx of Giza (Sphinx) which can be literally translated as the father of the dead or a terrifying one is a statue located in Giza Plateau, at the banks of River Nile, Egypt. It was made between the years c. 2558–2532Â  BC during the time when Egypt was under the leadership of Pharaoh Khafra. Just like Khafre Enthroned, this statue has a significant role to play in the lives of the Egyptians. However, the 241Â  ft long, 63Â  ft wide, and 66.34Â  ft high statue depicts an image of a mystical creature which has got a human head and a lion’s body. Thus, it stands as the largest monolithic statue in the entire globe. For this reason, it has had different interpretations especially in the contemporary society. Whereas the London Imperial College’s Surgeon Huan Ashrafian associates it to a depiction of a person suffering from a disease in disease with lion-like conditions, it has been linked to the solar worship that was so prominent amongst the Ancient Egy ptians. This is so because the image of lion has been synonymous with the

Internationalization

Internationalization 1. Preface This paper has been written for the course Societal Developments Institutions. The topic of this paper, knowledge sharing in virtual teams, is primarily focused on the Internationalization aspect of this course. But also aspects from other courses of the Master of Organizational Sciences (Msc OS), like Complexity within Organizations and Organizational Dynamics, are represented in this paper. Virtual teams and especially the knowledge sharing within such a team seemed very interesting to me. The broad link of this topic with the different courses of Msc OS was attractive to me, but also the growth in popularity of using this kind of the teams in nowadays business motivated me into doing this research. I hope this inquiry about knowledge sharing in virtual teams can facilitate virtual teams in knowing the challenges ahead, and help virtual team managers and -designers in benefit better from the advantages of virtual teams. Furthermore, after reading this paper I hope you, as reader, are (even more) inspired about the possibilities of working with virtual teams in ‘the collaboration economy. Key concepts: Internationalization, globalization, virtual teams, knowledge sharing. 2. Introduction In todays society people have adopted media technologies, such as e-mail, chat, and videoconferencing, that enable them to ‘go virtual and communicate with other individuals from all over the world. Currently, there are 1,733,993,741 internet users around the world (Internet world Stats, 2009). Because of those technological innovations it is possible to collaborate with other people regardless there geographical position. The last couple of years, next to those technological developments, two other mechanisms developed in a historical way globalization and demography. Tapscott and Williams argued in their book Wikinomics (2006): The three mechanisms: technology, globalization and demography are influencing the world towards a new economy, the collaboration economy. Emerging globalization demands and facilitates new forms of economic collaboration and provides all businesses who are seeking for unique talents to fix their problems with talented employees from over the whole world. And demographically there is also a shift. A new generation, bigger than the babyboom generation, the internet generation will dominate the 21ste century because of her demographical presence. This generation has grown up with internet and will utilize this technology in an efficient way and will change the status-quo in a radical way. Doing business and the way of collaborating in business will also change. Old monolithic multinationals which creates added value in a closed hieratically structure is quickly outdated. Successful businesses nowadays need open and porous bo rders and should compete using knowledge, resources and capacities outside the organization. Even heavy, capital intensive production industries will not be an exception. Also Ilinitch, DAveni Lewin (1996) addressed those changes; by opening their special issue on new organizational forms and hyper-competitive environments by nothing that, organizations are facing strong forces of change: globalization, demographic shifts, advances in technology, and the demassification of society. In response to those changes and shifts organizational forms are proliferating. One such new organizational form is found in virtual teams, sometimes called distributed teams (Saunders Ahuja, 2006). Virtual teams are, in summary, technology mediated groups of people in various places around the world that work together on common tasks (Hardin, Fuller, and Davidson, 2007). Currently those virtual teams are widely embraced by modern businesses. A motive of this popularity is that they can help organizations adapt better. They may provide firms with advantages such as increased utilization of employee-time, round-the-clock workforce availability, and the opportunity to leverage knowledge and expertise around the world (Paul, Seetharaman, Samarah Mykytyn, 2004). Virtual teams bring organizations also some other advantage: reduced travel expenses, Co2 emissions, and less working time wasted on traveling (Lu, Watson-Manheim, House, Matzkevich, 2005). This increasing use of virtual teams is also noted by the Wall Street Journal. It reports that more than half of companies with more than 5000 employees use virtual teams (de Lisser, 1999) Also, a survey by the Gartner group found that more than 60% of professional employees work in virtual teams (Kanawattanachai Yoo, 2002). The growth in popularity of virtual teams inquires a summary of how to manage such a team in an efficient an effective way. Questions about what are important factors in managing successful global virtual teams needed to be answered. In this inquiry I will address those success factors in case of knowledge sharing in global virtual teams by answering the question: â€Å"What are success factors of knowledge sharing in virtual teams, with team members across the whole globe?†. This enquiry is focused on knowledge sharing in virtual teams because those dispersed teams in particular need to share knowledge, experience and insights in order to function successfully (Rosen, Furst, Blackburn, 2007). The aim of this paper is to facilitate virtual team managers and -designers with a summary of virtual team success factors in knowledge sharing by which they can benefit better from the advantages of virtual teams. Firstly I will address the theoretical background of virtual teams. In this theoretical background I will explain the organizational need for virtual teams, give a definition of virtual teams, deal with the key feature of virtual teams; the absence of face-to-face contact and I will give an insight in the knowledge sharing mechanism. In the second part of this paper I will focus on answering the research question based on earlier researches and literature references. This will be followed by a brief conclusion and recommendations of those success factors in knowledge sharing to facilitate virtual team managers and -designers with a practical summary. 3.

Diabetes :: essays research papers

What is diabetes? Diabetes mellitus is a group of diseases characterized by high levels of blood glucose resulting from defects in insulin secretion, insulin action, or both. Diabetes can be associated with serious complications and premature death, but persons with diabetes can take measures to reduce the likelihood of such occurrences. 15.7 million people -- 5.9% of the population -- have diabetes. But only 10.3 million people are diagnosed so that leaves 5.4 million people not diagnosed. Studies have found death rates to be twice as high among middle-aged people with diabetes as among middle-aged people without diabetes. Based on death certificate data, diabetes contributed to 193,140 deaths in 1996. Diabetes was the seventh leading cause of death listed on U.S. death certificates in 1996, according to CDC's National Center for Health Statistics. Diabetes is believed to be underreported on death certificates, both as a condition and as a cause of death. 6.3 million. 18.4% of all people 65 years and older have diabetes. 15.6 million. 8.2% of all people 20 years and older have diabetes. 123,000. 0.16% of all people under age 20 have diabetes. Prevalence data for diabetes among Asian Americans and Pacific Islanders are limited. Some groups within this population are at increased risk for diabetes. For example, data collected from 1988 to 1995 suggest that Native Hawaiians are twice as likely to have diagnosed diabetes as white residents of Hawaii. The four types of diabetes are:  · Type 1 diabetes was previously called insulin-dependent diabetes mellitus (IDDM) or juvenile-onset diabetes. Type 1 diabetes may account for 5% to 10% of all diagnosed cases of diabetes. Risk factors are less well defined for type 1 diabetes than for type 2 diabetes, but autoimmune, genetic, and environmental factors are involved in the development of this type of diabetes  · Type 2 diabetes was previously called non-insulin dependent diabetes mellitus (NIDDM) or adult-onset diabetes. Type 2 diabetes may account for about 90% to 95% of all diagnosed cases of diabetes. Risk factors for type 2 diabetes include older age, obesity, family history of diabetes, prior history of gestational diabetes, impaired glucose tolerance, physical inactivity, and race/ethnicity. African Americans, Hispanic/Latino Americans, American Indians, and some Asian Americans and Pacific Islanders are at particularly high risk for type 2 diabetes.  · Gestational diabetes develops in 2% to 5% of all pregnancies but disappears when a pregnancy is over.

The phenomenon of bipolar affective disorder

The phenomenon of bipolar affective disorder has been a mystery since the 16th Century. History has shown that this affliction can appear in almost anyone. Even the Great painter Vincent Van Gogh is believed to have had bipolar disorder. It is clear that in our society many people live with bipolar disorder; however, despite the abundance of people suffering from it, we are still waiting for definite explanations for the causes and cure. The one fact of which we are painfully aware is that bipolar disorder severely undermines its† victims ability to obtain and maintain social and occupational success. Because bipolar disorder has such debilitating symptoms, it is imperative that we remain vigilant in the quest for explanations of its causes and treatment. Affective disorders are characterized by a smorgasbord of symptoms that can be broken into manic and depressive episodes. The depressive episodes are characterized by intense feelings of sadness and despair that can become feelings of hopelessness and helplessness. Some of the symptoms of a depressive episode include anaerobia, disturbances in sleep and appetite, psychomotor retardation, loss of energy, feelings of worthlessness, guilt, ifficulty thinking, indecision, and recurrent thoughts of death and suicide (Hollandsworth, Jr. 1990 ). The manic episodes are characterized by elevated or irritable mood, increased energy, decreased need for sleep, poor judgment and insight, and often reckless or irresponsible behavior (Hollandsworth, Jr. 1990). Bipolar affective disorder affects approximately one percent of the population (approximately three million people) in the United States. It is presented by both males and females. Bipolar disorder involves episodes of mania and depression. These episodes may alternate with profound epressions characterized by a pervasive sadness, almost inability to move, hopelessness, and disturbances in appetite, sleep, in concentrations and driving. Bipolar disorder is diagnosed if an episode of mania occurs whether depression has been diagnosed or not (Leiby,1988). Most commonly, individuals with manic episodes experience a period of depression. Symptoms include elated, expansive, or irritable mood, hyperactivity, pressure of speech, flight of ideas, inflated self-esteem, decreased need for sleep, distractibility, and excessive involvement in reckless activities (Hollandsworth, Jr. 1990). Rarest symptoms were periods of loss of all interest and retardation or agitation (Gurman, 1991). As the National Depressive and Manic Depressive Association (MDMDA) have demonstrated, bipolar disorder can create substantial developmental delays, marital and family disruptions, occupational setbacks, and financial disasters. This devastating disease causes disruptions of families, loss of jobs and millions of dollars in cost to society. Many times bipolar patients report that the depressions are longer and increase in frequency as the individual ages. Many times bipolar states and psychotic states are isdiagnosed as schizophrenia. Speech patterns help distinguish between the two disorders (Turner,1989). The onset of Bipolar disorder usually occurs between the ages of 20 and 30 years of age, with a second peak in the mid-forties for women. A typical bipolar patient may experience eight to ten episodes in their lifetime. However, those who have rapid cycling may experience more episodes of mania and depression that succeed each other without a period of remission (DSM III-R). The three stages of mania begin with hypo mania, in which patients report that they are energetic, extroverted and ssertive (Hirschfeld, 1995). The hypomania state has led observers to feel that bipolar patients are â€Å"addicted† to their mania. Hypo mania progresses into mania and the transition is marked by loss of judgment (Hirschfeld, 1995). Often, euphoric grandiose characteristics are displayed, and paranoid or irritable characteristics begin to manifest. The third stage of mania is evident when the patient experiences delusions with often- paranoid themes. Speech is generally rapid and hyperactive behavior manifests sometimes associated with violence (Hirschfeld, 1995). When both manic and depressive ymptoms occur at the same time it is called a mixed episode. Those afflicted are a special risk because there is a combination of hopelessness, agitation, and anxiety that makes them feel like they â€Å"could jump out of their skin†(Hirschfeld, 1995). Up to 50% of all patients with mania have a variety of depressed moods. Patients report feeling dysphonic, depressed, and unhappy; yet, they exhibit the energy associated with mania. Rapid cycling mania is another presentation of bipolar disorder. Mania may be present with four or more distinct episodes within a 12-month period. There is now evidence to uggest that sometimes rapid cycling may be a transient manifestation of the bipolar disorder. This form of the disease exhibits more episodes of mania and depression than bipolar. Lithium has been the primary treatment of bipolar disorder since its introduction in the 1960's. It is main function is to stabilize the cycling characteristic of bipolar disorder. In four controlled studies by F. K. Goodwin and K. R. Jamison, the overall response rate for bipolar subjects treated with Lithium was 78% (Turner,1998). Lithium is also the primary drug used for long- term maintenance of bipolar disorder. In a majority of bipolar patients, it lessens the duration, frequency, and severity of the episodes of both mania and depression. Unfortunately, as many as 40% of bipolar patients are either unresponsive to lithium or cannot tolerate the side effects. Some of the side effects include thirst, weight gain, nausea, diarrhea, and edema. Patients who are unresponsive to lithium treatment are often those who experience dysphonic mania, mixed states, or rapid cycling bipolar disorder. One of the problems associated with lithium is the fact the long-term lithium treatment has been associated with decreased hyroid functioning in patients with bipolar disorder. Preliminary evidence also suggest that hypothyroidism may actually lead to rapid-cycling (Gurman,1991). Pregnant women experience another problem associated with the use of lithium. Its use during pregnancy has been associated with birth defects, particularly Ebstein's anomaly. Based on current data, the risk of a child with Ebstein's anomaly being born to a mother who took lithium during her first trimester of pregnancy is approximately 1 in 8,000, or 2. 5 times that of the general population (Leiby,1988). There are other effective treatments for bipolar disorder that are used in cases where the patients cannot tolerate lithium, or have been unresponsive to it in the past. The American Psychiatric Association's guidelines suggest the next line of treatment to be Anticonvulsant drugs such as valproate and carbamazepine. These drugs are useful as antimanic agents, especially in those patients with mixed states. Both of these medications can be used in combination with lithium or in combination with each other. Valproate is especially helpful for patients who are ithium noncompliant, experience rapid-cycling, or have comorbid alcohol or drug abuse. Neuroleptics such as haloperidol or chlorpromazine have also been used to help stabilize manic patients who are highly agitated or psychotic. Use of these drugs is often necessary because the response to them are rapid, but there are risks involved in their use. Because of the often severe side effects, Benzodiazepines are often used in their place. Benzodiazepines can achieve the same results as Neuroleptics for most patients in terms of rapid control of agitation and excitement, without the severe side effects. Antidepressants such as the selective serotonin reuptake inhibitors (SSRI†s) fluovamine and amitriptyline has also been used by some doctors as treatment for bipolar disorder. A double-blind study by M. Gasperini, F. Gatti, L. Bellini, R. Anniverno, and E. Smeraldi showed that fluvoxamine and amitriptyline are highly effective treatments for bipolar patients experiencing depressive episodes (Leiby,1988). This study is controversial however, because conflicting research shows that SSRI†s and other antidepressants can actually precipitate manic episodes. Most doctors can see the usefulness of ntidepressants when used in conjunction with mood stabilizing medications such as lithium. In addition to the mentioned medical treatments of bipolar disorder, there are several other options available to bipolar patients, most of which are used in conjunction with medicine. One such treatment is light therapy. One study compared the response to light therapy of bipolar patients with that of unipolar patients. Patients were free of psychotropic and hypnotic medications for at least one month before treatment. Bipolar patients in this study showed an average of 90. 3% improvement in their depressive ymptoms, with no incidence of mania or hypomania. They all continued to use light therapy, and all showed a sustained positive response at a three month follow-up (Turner,1998). Another study involved a four week treatment of bright morning light treatment for patients with seasonal affective disorder and bipolar patients. This study found a statistically significant decrement in depressive symptoms, with the maximum antidepressant effect of light not being reached until week four (Hollandsworth, Jr. 1990). Hypomanic symptoms were experienced by 36% of bipolar patients in this study. Predominant hypo manic symptoms included racing thoughts, deceased sleep and irritability. Surprisingly, one-third of controls also developed symptoms such as those mentioned above. Regardless of the explanation of the emergence of hypo manic symptoms in undiagnosed controls, it is evident from this study that light treatment may be associated with the observed symptoms. Based on the results, careful professional monitoring during light treatment is necessary, even for those without a history of major mood disorders. Another popular treatment for bipolar disorder is electro-convulsive hock therapy. ECT is the preferred treatment for severely manic pregnant patients and patients who are homicidal, psychotic, catatonic, medically compromised, or severely suicidal. In one study, researchers found marked improvement in 78% of patients treated with ECT, compared to 62% of patients treated only with lithium and 37% of patients who received neither, ECT or lithium (Gurman,1991). A final type of therapy is outpatient group psychotherapy. According to Dr. John Graves, spokesperson for the National Depressive and Manic Depressive Association has called attention to the value f support groups, and challenged mental health professionals to take a more serious look at group therapy for the bipolar population. Research shows that group participation may help increase lithium compliance, decrease denial regarding the illness, and increase awareness of both external and internal stress factors leading to manic and depressive episodes. Group therapy for patients with bipolar disorders responds to the need for support and reinforcement of medication management, and the need for education and support for the interpersonal difficulties that arise during the course of the disorder.

How Hamlet Changes Throughout the Play

The changes in Hamlet's personality are reflected in his changes in costume. At first, there is the Hamlet in the â€Å"nighted colour†, in mourning for his father and resentful of his mother and uncle. This is Hamlet in Act one. He is passive and reactive, making snarky remarks under his breath and behind the king's back but being sullen and unresponsive in his presence. After the visit of the Ghost, Hamlet changes. Ophelia describes his costume as â€Å"his doublet all unbraced, no hat upon his head, his stockings fouled and down-gyved to his ankle. This is Hamlet of the antic disposition. His pretense of insanity gives him the liberty to sharpen his wit on the various spies which come to sound him out. He becomes more active, arranging for and essentially directing the play The Murder of Gonzago, but he is a perfectionist, and cannot see his way to killing Claudius without the circumstances being just right. He thinks he has got them right but he is wrong–it's Polonius behind the arras and not Claudius. Then he is sent to England. He discovers that Claudius is not going to wait for the perfect opportunity, but has already made arrangements to have Hamlet killed. He changes again. He arranges for the deaths of Rosencrantz and Guildenstern, and when the pirates attack, he takes the opportunity to board their ship, and bribes them to return to Denmark. He arrives on the shores â€Å"naked and . . . alone†. â€Å"Naked† here means that he has only the clothes he stands up in, whatever he can find. Hamlet is now an opportunist. He no longer insists that the conditions be perfect. He will take his opportunity where he finds it. He becomes a fatalist: â€Å"There is a special providence in the fall of a sparrow . . . the readiness is all. † It is when he reaches this stage in his journey that he can do what he wants to do and needs to do. He expresses his love for Ophelia (too late) and is able to take his revenge on Claudius (almost too late).

What to Do When a Dangling Participle Defies Revision

What to Do When a Dangling Participle Defies Revision What to Do When a Dangling Participle Defies Revision What to Do When a Dangling Participle Defies Revision By Mark Nichol A dangling participle is a construction in which the participle, or verb, that follows the subject of a sentence is not associated with an introductory phrase, leaving the participle dangling. For example, in â€Å"As a client, we know this new standard may affect you and your financial-reporting requirements,† the subject â€Å"we† is identified in the introductory phrase (which modifies we) â€Å"as a client.† But â€Å"as a client† modifies you, not we, and because we, not you, is the subject, that phrase is not appropriate at the head of the sentence. Often, such phrases can simply be relocated (with or without slight rewording) so that it is adjacent to the word it modifies, and the subject can begin the sentence. However, in this case, each of several permutations is problematic: In â€Å"We know, as one of our clients, that this new standard may affect you and your financial-reporting requirements,† the implication is that the party identified as â€Å"we† is one of its own clients. â€Å"We know that, as one of our clients, this new standard may affect you and your financial-reporting requirements† implies that the new standard, not the person identified as â€Å"you,† is a client of â€Å"we.† And â€Å"We know that you, as one of our clients, and your financial-reporting requirements may be affected by this new standard† suggests that being one of the clients of â€Å"we† is the cause of being affected by the new standard. In this case, the best solution is probably to further distinguish the two components of this sentence- the statement that the reader is a client of the business that produced the message and the information about the implications of the new standard- in a revised and expanded statement such as this: â€Å"You are one of our valued clients, and we want to make sure you know that this new standard may affect you and your financial-reporting requirements.† Want to improve your English in five minutes a day?

Chuck Close And Photorealism Research Paper Example | Topics and Well Written Essays - 2250 words

Chuck Close And Photorealism - Research Paper Example A graduate of the Yale University School of Art and once a teacher of arts in University of Massachusetts, Chuck Close became a significant figure in artistic society of the latter half of the twentieth century known for his remarkable style of painting large-scale portraits. â€Å"Close learned to paint like an Abstract Expressionist when he was a student at Yale† . Yet, while the painter’s preferences in his tuition years centered mainly on abstract impressionism, training in Europe and the MFA program have added a pinch of more modern trends including minimalism and pop art. However, the artists managed to choose the domain for his work rather early: human faces and their versatile portrayals in photography and paint became the major course for the artist’s development, while the painterly style and instruments changed for several times. During his teaching career in Amherst, the painter experimented with pop-inspired elements in portraiture, engaging photogra phic images for the first time in his work: those were the daring and large realistic pictures of nude models including Bid Nude of 1967. However, it was his Big Self-Portrait that served as an important milestone in development of his style, for this painting literally opened the series of the famous photorealistic ‘heads’ on a larger-than-life scale and with exaggerated and unflattering manner of depiction, his friends and family as models, first in grayscale and then in color. Later period of Close’ work was marked by domination of pointillism.

Media and popular culture in China Essay Example | Topics and Well Written Essays - 1000 words - 1

Media and popular culture in China - Essay Example Chinese history and culture have always been difficult to understand for western intellectuals. Although trade relationships between China and the rest of the world had gone on for centuries, there is always the perception of that the country represents the other, the Orient. This construct is noted to be in complete contrast to the Occident. Seen in light of this dichotomy, while sentiments and views expressed by Chinese leaders might appear contradictory or paradoxical to the western observer, they are not necessarily so for the Chinese people themselves. Chinese leader Dengs statement to the party to â€Å"Guard against the Right, but primarily against the Left† can hence be interpreted to be logically and practically plausible. The rest of this essay will elaborate on this thesis. Ever since the communist revolution of 1945 and the rise to power of the Communist Party of China (CCP), Marxist-Leninist thought have been the backbone of much of public policy. Under the iron rule of Mao Zedong, although several millions of Chinese lost their lives through their acts of rebellion, communist ideology has been reverentially promoted both within the party and among the general public. This is not to say that there are no contradictions and countervailing tendencies within the party leadership. If anything, when one looks at the priorities of Chinese leadership during the last six decades, it is clear that their holding on to authority is of paramount importance. Whether communist principles get implemented through public policy has been secondary to monopolization of power. And since the greatest threat to power comes from popular movements, as opposed to business interests, Dengs warning against the Left makes perfect sense. Although, the tendency to repress and sub due the public have taken new modes in recent decades, it was frequent even during the reign of Mao Zedong, the founding leader of the CCP. In 1958, Mao introduced a highly
