The Relationship Between Inflation And Unemployment

The relationship between inflation and unemployment is a topic, which has been debated by economists for decades. It is this debate that has made the opinions about it evolve. In this essay, the controversial topic will be discussed by viewing different economists’ opinions on that according to time sequencing. Inflation is an increase in price levels within an economy. Basically it means that you will have to pay more for the same goods. Unemployment is even more straightforward. It means that a person is available for employment but is unable to find employment. Lastly, the unemployment rate, which is the percentage of potential workers that are unemployed, is used to measure unemployment (Mankiw 1992). The debate about the relationship between inflation and unemployment is mainly based on the famous â€Å"Phillips Curve†. This curve was first discovered by a New Zealand born economist called Allan William Phillips. In 1958, A. W. Phillips published an article â€Å"The relationship between unemployment and the rate of change of money wages in the United Kingdom, 1861-1957†, in which he showed a negative correlation between inflation and unemployment (Phillips 1958). When the unemployment rate is low, the inflation rate tends to be high, and when unemployment is high, the inflation rate tends to be low, even to be negative. Two years later, economists Paul Samuelson and Robert Solow, who adhere to the Keynesian school of economics, also published an article, showing the sameShow MoreRelatedRelationship Between Unemployment And Inflation2301 Words   |  10 PagesThe relationship between unemployment and inflation has been the subject of heated debate, stimulate academic divide between macroeconomics because the relationship is difficult to explain.

The island is called Kankakee in Japan and Oddity in China. The territorial dispute was botched in 2012 by Tokyo, led at the time by the now- discredited Democratic Party of Japan. Reacting to China’s increasingly intrusive presence in the waters around the Japanese-administered islands, and fearing that maverick former Tokyo Governor Shinto Ashier would carry through his threat to purchase the islands, then-Prime Minister Whooshing Nodal nationalized several of the islands after buying them from heir private owners in September 2012. We will write a custom essay sample on Sample Position Paper or any similar topic only for you Order Now China responded instantly with anti- Japanese riots and a freezing of diplomatic relations. Chinese patrol vessels and fishing boats began tense face-offs with Japan’s Coast Guard. Within months, both nations’ air forces began more active aerial patrols. One year and two months ago, China upped the ante by flying surveillance drones in such contested airspace. Japan responded by saying it would shoot down any drone that refused to leave the skies above the islands. Beijing says that any attack on its drones would be an act of war. In another sign of high tensions in North East Asia, Japan announced that it scrambled fighter jets on the 7th January 2014 to head off a Chinese civilian aircraft near disputed islands. The Y-12 propeller plane entered Japan’s air defense identification zone CADIS), but not the airspace around the Kankakee islets, before heading back to China. The incident is the first reported since China announced its own ADZ last November in the East China Sea, including the disputed islands, provoking an aggressive response from both the United States and Japan. The Obama administration immediately declared that US military aircraft would ignore the new Chinese protocols and flew nuclear-capable 8-52 bombers through the zone without informing Chinese authorities. US allies Japan and South Korea followed suit, raising the danger that an error or miscalculation could lead to a clash with the potential for escalation into an open conflict. The warfare is still continued and Japan did boost their defense budget. Controlling the use of drones for warfare is only in the hands of the nation’s leaders. China’s ambassador has accused Japan’s Prime Minister, Shinto Abe, f â€Å"raising the specter of militarism† and putting his country on a â€Å"perilous path† that could threaten global peace. Lie Gaming said Abe, who has challenged the widely held view that Japan was an aggressor in the second world war, had contributed to a dramatic rise in tensions in north-east Asia with his hawkish policies and a recent visit to a controversial war shrine. The international community, Lie warned, should remain on a â€Å"high alert†. Relations between China and Japan – which enjoy expansive trade ties – have reached their lowest point in decades over competing claims to the Kankakee islands in the East China Sea, which are administered by Japan but also claimed by China.

Physical Therapy Abdominal Surger

Question: Case Scenario Mary, a 29 year old healthy, active female, has just returned from a trip abroad. One week before returning to this country she began noticing some right shoulder and upper thoracic pain. Initially she thought it might be a mild strain since she had been carrying heavy bags throughout the different train stations and airports. Since returning home, the pain increased. She saw her physician for the problem the week after her return. An x-ray of the shoulder was normal. She was given Motrin anti-inflammatory medication and referred to physical therapy. During the physical therapy evaluation, she reported that she was in good health except for the pain in the right shoulder region. However, she did notice her urine had been noticeable darker since she had initially seen the doctor but reported no pain with urination or back pain. The objective assessment by the physical therapist was as follows: In standing the patient presented with a mild mid-thoracic spinal kyphosis. Thoracic symptoms were not provoked with active trunk movements. Passive accessory movements using central and unilateral pressures over the thoracic spine were unremarkable for pain except for some hypomobility between T5-T8. On palpation of the mid rhomboids and right upper trapeziums, tenderness was noted. Shoulder arm range of motion was restricted in the last 25% of motion in flexion and external rotation. Special test for impingement was unremarkable. Shoulder strength was normal and distal sensation intact. Based upon the findings, the physical therapist began treatment of the right shoulder. The patient proceeded with manual therapy and exercise for several visits gaining in right shoulder range of motion and noting a decrease in her shoulder pain. The beginning of the second week of therapy the patient called in sick and indicated she was not going to make her appointment. She returned on her next scheduled appointment. She reported to the therapist that during the weekend she had right upper abdominal pain and that her urine appeared to be darker and noted a change in bowel habits. In addition she began to note a slight yellowish to the skin as well as a fever from time to time. The physical therapist cancelled the treatment and notified the patient's physician of the change in status. 1. What do you think is going on with this patient? 2. What history, symptoms, and patient information clued the therapist to refer the patient back to the physician? 3. Why was therapy canceled? Explain your answer. 4. Active and passive mobility test of the thoracic spine failed to provoke any significant symptoms. During the initial assessment, what type of follow-up questions should the therapist have asked to further investigate the pain? Additional Questions:Respond to these questions using information from your textbook and your clinical practice. DoNOTrefer to the scenario above. Each question is worth 2 points. 1. Where does visceral pain occur in the abdominal region? Why is visceral pain considered hard to localize with the abdomen? 2. Define dysphagia. Other than occurring in gastrointestinal disorders, name at least two other conditions where the symptoms of dysphagia can occur. 3. Low back pain may be the only symptom associated with what type of cancer affecting the digestive system? 4. Explain the different ways of bleeding in the GI tract can be manifested and the possible causes. 5. What is the significance of Kehr's sign? 6. What areas of the body can gastrointestinal (GI) disorders refer pain to? Answer: (1) Mary, a healthy lady, just returned from the trip.The problem with the patient started as pain in right shoulder and upper thoracic region before her return to the country. As her x-ray report was normal physician suggests her to go for physical therapy and gave her anti-inflammatory drug and her pain was relieved to some extent. The patient is facing the problem of dark urination from the day beginning of her appointment with the physician, but she is not having any pain. Dark urination without any burning sensation, in this case, helps to rule out the chance of urinary tract infection. According to van Slambrouck et al., (2013), dark coloration of urine can happen due to dysfunction of liver.Bile is produced at liver and gets accumulated in the gall bladder. Excess bile excretes out through the kidney and makes the color urine darker. In this case as fever is not associated with chill the case of biliary obstruction can be ruled out (Yang 2015). T5-T8 region is the position where the liver is located. The patient is having the dark urine from the very first day and it is still continuing and additionally, her skin color is changing. Yellow discoloration of skin with fever is a symptom of liver ailment like jaundice. It takes few days to week to develop symptom of jaundice (Barr, 2013).Upper abdominal pain accompanying the other symptoms is also an indicator of jaundice. As stated by Yabluchansky et al., (2015), change in bowel habits and yellowing of skin with fever is warning symptoms of hepatitis C. Looking at the above conditions, it can be suggested that the patient is suffering from the liver related problem. (2) The patient has a history of a recent foreign trip. She also developed symptoms of upper abdominal pain and intermittent fever. A change of skin color to yellow is also reported by the therapist. The patient also informed that there is change in the color of urine and change in bowel habit. This entire series of incidents clued the therapist to refer the patient to the physician. (3) The therapy was canceled by the therapist as the condition of the patient deteriorated when she developed some other symptoms which may have risen due to some other reason. Patient has returned from a foreign trip with a history of pain in her upper thoracic and right shoulder region. Later she went through physiotherapy with anti-inflammatory medication as her X-ray report was normal. When the patient was referred to the physiotherapist she had mild thoracic kyphosis and hypo-mobility was observed between T5-T8 regions. Tenderness on palpitation of mid thromboids and upper trapeziums with normal shoulder strength was also observed before she was referred to a physiotherapist. During her second week of appointment to the physiotherapy the patient developed the symptoms of upper abdominal pain and irregular bowel movement. She also reported that dark urination problem was consistent for more than two weeks, and she is also having fever at regular interval. (4) A physiotherapist must evaluate and examine all the probable causes of the patients symptoms. A visit to the therapist for a number of times the patient was able to gain right shoulder range of motion and a decrease in shoulder pain. In this case, it was thought that the patients symptoms were due to pain in shoulder. Therapist should have asked the questions When is the pain beginning? How long is the pain sustaining? Is there any activity which is increasing the pain? Whether the pain is radiating or localized? Is there any previous injury? (1) Abdominal cavity being the largest body cavity contains the following organs liver, adrenal glands, gallbladder, spleen, pancreas, small intestine kidneys, and large intestine. Abdominal visceral pain arises from visceral peritoneum. Visceral pain is hazy, crampy, tedious which is hard to describe. Visceral pain abdomen is hard to locate also (Brglum Jensen, 2012). As visceral organs are connected with spinal cords and send afferent stimuli to spinal cord. A number of nerve endings in the visceral organs of abdomen are comparatively less than other organs like skin. This is also due to widespread deviation of visceral input within the CNS (2) Dysphagia: Dysphagia is a medical term used to indicate difficulty in swallowing. This also refers to condition in which a sensation of stacking some thing in the tract from mouth to stomach. According to Tsuzuki et al., (2012) dysphagia can happen due to conditions other than gastrointestinal disorders. Lung cancer and lymphoma in can create similar type of symptoms as dysphagia. Infectious disease such as tuberculosis may also develop dysphagia like symptoms. Cardiovascular diseases like dilated auricles can also cause esophageal dysphagia. (3) Pancreatic cancer is associated with only symptoms of lower back pain. (4) Bleeding may occur in GI in different ways. Vomiting red blood or heatemesis is bleeding from upper gastrointestinal tract. Black blood vomiting is an indication of upper gastrointestinal tract bleeding. The color of vomitus becomes dark due to exposure to gastric acid of heme molecule of red blood cells. Peptic ulcer is considered to be the cause of black blood vomiting. Blood in stool is the excretion of fresh blood in or with stool. This kind of bleeding pattern is associated with lower GI tract due to due to hemorrhoids, colorectal cancer, ulcerative colitis, inflammatory bowel disease, etc. Black stool or melena is associated with peptic ulcer or bleeding from upper GI tract. (5) Kehrs sign is a kind of referred pain. This indicates a violent pain in the shoulder (Intravia DeBerardino, 2013). This happens due the presence of blood in the peritoneal cavity. When the pain is in the left shoulder, then it is an indication of ruptured spleen. Often this discovery is endorsed with German surgeon Hans Kher. (6) Pain can be felt at different region of body, but it can have its origin in gastro intestinal tract. Pain in upper right abdomen and right shoulder area may be due to dysfunctional gallbladder. Mild to moderate pain in right shoulder may be due to hepatitis. Manifestation of esophageal pain is heart burn or chest pain. Acute pancreatitis or pancreatic pain injury refers to the left shoulder. Gastric ulcer pain passes on to substernal region while perforated ulcer pain refers to one or both the shoulders.

Organisational Culture Essay Example

Organisational Culture Essay The Intel Corporation produces microprocessors that are used in computers. It has a market share of over 75% and has been praised for its highly innovative culture. Do you think that an innovative culture can be relied on to guarantee the future success of a business? Justify your answer with reference to Intel and/or other organisations you know. (40 marks) An organisation’s culture refers to ‘the way we do things around here’ and is determined by the values, attitudes and beliefs of the people who work within it. As such, culture will undoubtedly influence the success of a business. In particular, it can be argued that an innovative culture can lead to business success because it enables companies to share ideas more freely and thus innovate and develop their business strategy. Furthermore, in light of Handy’s view of â€Å"discontinuous change† being ever more present in the business world, an innovative culture is likely to enable business to be flexible enough to cope with challenges that the future holds. However, it is important to bear in mind that when a business possesses over 75% market share that it benefits from economies of scale which can be an important determinant of success, regardless of culture. Perhaps more importantly, not every success international business possesses an innovative culture. A successful business strategy can be underpinned by other business cultures and thus the type of industry a business is in, and the different challenges it faces may determine what is the most suitable culture for them.

The Intel corporation operate a very innovative culture which has lead to huge dominance of the market, capturing 75% market share after the production of microprocessors used in computers. Another example where innovation has lead to success is at Google, where CEO Eric Schmidt commits to innovation, making sure all employees are comfortable sharing ideas and opinions. The relaxed feel around the company allows employees to be creative, which has allowed Google to be one step ahead of competitors, which is especially important working in a technological industry. BMW use a similar culture where everyone is expected to help find solutions. They have a network of committed associates with few hierarchical barriers, allowing every employee to voice their opinion. This culture has allowed BMW to promote new products and get the product just right through thousands of brainstorming sessions. These examples show how innovation can lead to success in technological industries. Innovative culture can be relied on to guarantee the future success of a business, as the external environment is constantly changing. This can be linked to Charles Handy’s theory of ‘discontinuous change’ which means that in the future change is constant, and therefore an innovative culture would most likely guarantee a business success. Being highly innovative would mean that managers would have to be flexible and react to the constantly changing external environment, therefore adopting an innovative culture would mean businesses would have to come up with ideas and strategies for the future in order for the business to remain competitive and successful. Innovative culture should equip firms with the ability to cope better with change. For example Intel’s strategy of diversification where they use tactics such as job swapping and controlled employee role changes to increase the efficiency of their teams. This is useful as the workforce is flexible to the externally changing environment, and can guarantee future success of a business as they would be able to react to any change within the business. Hence I think that an innovative culture can determine the future success of the business, especially in a technological industry as the external environment is constantly changing meaning a firm has to be flexible and prepared to react and respond if it wishes to remain competitive and profitable. If a business did not react to changes and maintained there current strategies and plans then this could have negative effects on the business such as a declining market share due to competitors coming up with new innovative ideas and hence a lower profit. One way in which we can see that an innovative culture cannot be relied on to guarantee the success of a firm is that there are other organisations that have a different cultural approach that have been very successful. I believe that the culture within Tesco has significantly helped it to become one of the most successful retailers in Britain. Tesco use a person and role culture which I believe have helped to contribute to the success of the firm, there are ‘six levels between the till operator and the CEO’ in Tesco and I would think that this would have helped lead to the success of the firm as employees would feel like an important asset of the firm and are therefore motivated to work harder for the benefit of the business. Also it is evident in Cadburys, the biggest confectionary retailer in England who take a role and task approach to their culture that an innovative culture is not needed to guarantee the success of a firm. I believe that the putting an emphasis on results and giving staff specific roles within the business has led to the success of Cadburys as there is a specific focus on achieving targets and working as a team which I believe can highly motivate employees. So it is evident in a range of businesses that an innovative culture is not the key to success in business, various different cultural approaches such as task and role can have a significant contribution towards the success of an organisation. However, it can be argued that the size of Intel’s organisation provides it with its main competitive edge. Intel has a market share of 75% bringing with it certain benefits that are arguably more influential to its success than its innovative culture. A firm of this size is likely to benefit from economies of scale, propagating lower unit costs that can lead to higher profit margins. Higher profit margins enable greater re-investment into the firm, allowing Intel to continuously expand. Therefore, it seems apparent that even without its innovative culture, the sheer size of the firm would enable it to compete successfully. However, one cannot say that a large firm is guaranteed future success as demonstrated by the IBM monopoly that quickly lost majority market share to Microsoft and today only operate within a business-to-business niche market. Although business â€Å"success† is essentially easy to measure through examining market share, revenue, profit and other such measures, the factors that lead to such success are less easy to see. Factors such as a strong business strategy, good leadership, a favourable competitive environment and culture all contribute to a business’s success but being able to separate out which factor contributes more to success is near impossible. Furthermore, being ble to measure how effective an innovative culture versus a role or person culture is very difficult. Ultimately, the ‘best’ culture will vary according to industry and the nature of the business structure itself. Some industries such as the technology industry has developed its products at an exponential rate, inconceivable just 20 years ago. The nature of such a fast moving industry relies on quick and consistent innovation which is no doubt dependent on an innovative, networked culture like the type we see at Google and BMW. Other industries such as retailing and supermarkets, however do not face such radical and constant need to develop their product offering, and factors such as good quality service and product quality may be more important. As a result, a role and person based culture are more likely to lead to success. However, in light of Handy’s â€Å"discontinuous change†theory, all businesses, regardless of industry will face an ever changing external environment and so although an innovate culture may not be the most suitable per se, having an element of innovation and flexibility is key to any business intending to succeed in the future.

Music1 essays

Music1 essays Does the music that is produced today have a direct affect on what teenagers in America will do? This is a question that many people over the last couple of years have asked constantly. With the recent Columbine incident, as well as the increase in school shootings, many people feel there is something to blame for the violence. In situations like these, art forms are usually the easiest to blame. There is no way to blame one person for the crimes at hand, and no one would like to believe that they just poorly raised their own children. Suddenly someone steps in and sees the teen listened to some sort of music, which is not acceptable by parents standards, and you have a culprit. The problem with this is that, not everyone who has ever listened to any sort of music has developed a desire to go shoot everyone in his or her school. No study has proven that music makes a person do anything but maybe listen to the song again. Therefore music has no direct affect on what people decide to do with their lives. Recently, shock-rock has become a very popular genre of music. A group named Marilyn Manson has been heavily in the media since 1995. This particular group bases its career on its shock value. When the Columbine shootings occurred, many people put the blame on Brain Warner, the lead singer of Marilyn Manson, because of his eccentric appearance and lyrics. Many American parents felt that his differences from a more mainstream act like Brittany Spears, made his lyrics all that more offensive. Since the two boys involved with the Columbine shootings listened to Marilyn Manson, he was ultimately blamed for their murderous rampage. The media however hardly touched on the fact that both the boys were often tormented at school for being different. Secondly, that they both had a deep hatred for the jocks that made fun of them everyda ...

Why did castles play such a key role both in the implementation of Essay

Why did castles play such a key role both in the implementation of rebellion by nobles and in its suppression by rulers between 1066 and 1224 - Essay Example They illustrate a key part of British history, particularly those that date from the early part of the Norman era and William the Conqueror’s rule as they are part of an era of political dissent and distrust of the crown. The rebellion of nobles against the crown, as exemplified by the Revolt of the Earls in 1075 and other acts of dissent, played a crucial role in the need for these castles, particularly as many were used to supress such uprisings. The purpose of this paper is to explore the role that castles played in the rebellions and their suppression, and the reason why they played such a crucial role in these events of history. It will also highlight the political importance of castles and their role in times of crisis, particularly with respect to who held control of these dominant buildings. In doing this, it will become clear why the Norman era is so inextricably linked with the huge surge in the number of castles that dominate the British landscape and why so many of these elements of history can be found still standing today. The first true British castles began to be built upon the Norman invasion of 1066 by William the Conqueror1.... As previously mentioned, the Norman invasion of England was not taken lightly by the aristocracy that already resided in the area, and William the Conqueror’s rule was marred by uprisings and rebellion by nobles, a hint at the struggles for political power to come in the next two centuries. One of the most significant struggles for power is known as the Revolt of the Earls, and occurred in 1075. Ralph de Gael, the Earl of Norfolk, and Roger de Breteuil, the Earl of Hereford, began to conspire to overthrow William as the King of England due to a number of conflicts, one involving the sanctioning of a marriage agreement4. Norwich Castle, one of the most important examples of Norman castle building efforts, was the site of Ralph’s efforts to remain protected during the rebellion, and for many months was successful in evading Norman involvement. However, Ralph returned to his native Brittany, leaving the castle in control of his wife, whereupon it became besieged and used f or protection of the Norman troops5. This early event in castle history shows how useful castles were to both uprising nobles and the reigning Norman leaders of the era, as the structures change political ownership as a reflection of power in the region6. Many English castles during the reign of William the Conqueror and subsequent kings were under the control of the reigning leader (royal castles) whilst the remainder were controlled by the aristocracy. This kind of conflicting control was not to stay static during the era, but a series of relocations of ownership through friendly and unfriendly requests was to occur.7 The castles themselves were additionally important because they were not simply standalone property, but

Entrepreneurial Self Reflective Analysis Essay Example | Topics and Well Written Essays - 1750 words

Entrepreneurial Self Reflective Analysis - Essay Example The essay presents a self-reflection analysis done by the researcher and based on the GET2 test while providing any contradicting or supportive arguments based on previous encounters. The overall result of the test that are presented in the essay also challenges the ability of the researcher to develop innovative ideas. The researcher considers this assumption both wrong and highly prejudiced. Different people have different abilities and ideas. It is explained that since we all have a different set of abilities and personal characteristics, the researcher believes the test does not give an excellent analysis regarding his overall creativity. The researcher then councluds that these test results also seem to contradict each other seeing that the researcher considers his risks suggesting that he prefers taking calculated moves. An example of a contradictory review is the idea that the researcher prefers giving orders and also being the team leader. The same test results also state tha t the researcher would be well suited in an intrapreneurship letting someone take charge and engage in risky activities. If the two results are by chance considered to be factual, then the researcher would also have a strong desire to lead any partner, and that would translate to taking a higher risk than them. According to the GET2 test, the researcher have an overall score of 63 percent that implies he is likely to have strengths in various enterprising characteristics and could also be enterprising in some contexts.

Social and emotional develop Essay Example for Free

Social and emotional develop Essay To support social and emotional develop and to provide positive guidance As an early Childhood Teacher I promote social-emotional development in my classroom by embedding my teaching practices throughout the day. Remaining sensitive to children’s needs helps them feel secure and confident, and acts as a model for effective social behavior. For example, I usually ask questions to help children find a solution to a social conflict that helps them develop problem-solving skills. I also tend to every day read a story and engage children in a conversation about a socially challenging situation witch serve as a lesson in handling social problems as well as in literacy. Self I greet each child and their parents daily. I provide plenty of praise and encouragement to the children about their activities and accomplishments. This action lets the children know that they are loved, appreciated and special. I help children feel good about them selves and build high self-esteem. I use games, books, songs, finger plays, etc. to help the children learn to accept themselves and others. I provide materials and activities that are age-appropriate so that each child can experience success. I also spend time with the children individually and I make sure they get plenty of hugs and affection throughout the day. Social – I teach the children how to socialize with each other daily. I provide activities and space for the children to play together. We discuss sharing, taking turns and working together in small/ large groups. I interact with the children one-on-one daily and encourage them to interact with each other. I also use games, books, video tapes, songs, pictures, etc. to teach the children about positive social skills. Guidance I try to anticipate negative behavior and redirect it positively into other activities. I provide plenty of materials and space to help eliminate conflicts. I talk to the children whenever they exhibit inappropriate behavior and let them know that we should be kind to our friends. Only positive guidance techniques are used with the children in my care. CS III a – I help children learn to do simple tasks for themselves. Each child has a personal space to keep its belongings. We play games that highlight each child’s name and do self-portraits. I also play â€Å"mirror† games and provide cultural books and materials to help the children learn to appreciate themselves and others. CS III b – I believe that children’s behavior needs to be understood and guided in a positive manner. I do this by example. I tell the children what I expect of them and use positive words to guide their behavior. As a child, discipline methods were just the opposite of what I practice in my classroom. There was no such thing as guidance techniques. Today, I am knowledgeable of child development, and I practice appropriate guidance techniques daily. My children are valued and accepted for who they are. I also use redirection, active listening, proximity control, simple rules with positive consequences and valuing/praising appropriate behaviors to work with all children, including the difficult/challenging child.

To Age or not to Age :: Essays

To Age or not to Age (1) In â€Å"Dr. Heidegger’s Experiment," Nathaniel Hawthorne expresses [Diction] that if given the chance to regain your youth, some would not have learned from their past mistakes, to change the way would live their life again. In â€Å"Dr Heidegger’s Experiment† Hawthorne uses his characters to describe how life experiences should have an impression in our lives. (2) Dr Heidegger was an old scientist, who has a very strange way of presenting himself. He works by himself in his study. Which many find to be a â€Å"very curious place.†(Pg. 578) [Frag -1] In his study there is a picture of a women [Hostage 50] who once was his lover. She was going to be the one that he was going to marry, but she had been affected with a disorder and had taken some of the pills he prescribed and died. â€Å"She had swallowed one of her lovers prescription’s and died on the bridal evening.†(Pg. 579) It is thought that Dr. Heidegger might have had something to do with her death, but it was unknown. â€Å"The greatest curiosity of the study remains to be mentioned.†(Pg. 579) [Why was this uotation included?] The doctor had an experiment that would turn back the hands of time, but he would not have any part of it, he just wanted to observe. [How is this paragraph related to the thesis?] (3) Dr. Heidegger called on four of his friends to help him with his experiment. [This topic sentence suggests a plot summary.] Mr. Medbourne who was a prosperous merchant in his early day (Pg. 579), Colonel Killigrew wasted his years on sinful pleasures (Pg. 579), Mr. Guscoigne was a ruined politician (Pg. 579), and Widow Wycherly was a beauty in her younger day, but had been isolated from society (Pg. 579). All of the friends had lived a life of relationships with all three men, [homosexual?] which almost caused them to kill each other over her, â€Å"had once been on the point of cutting each other's throats for her sake.†(Pg. 579) [This quotation is inaccurate.] This is what caused for her to be an outcast with the town. â€Å"scandalous stories which had prejudiced the gentry of the town against her.†(Pg. 579) [Frag - 1] When asked to participate in the experiment, they were all a little skeptical.

Psy/310 Perspectives Paper Essay

Each psychological perspective has pioneers who have done the research to not only present the perspective, but to also prove how beneficial it is. John B. Watson is one of the great pioneers who created and popularized the behavioral perspective. He had many followers who believed in what he said, including B.F. Skinner. Although Skinner was truly influenced by Watson, he had his own ideas and theories that he later proved to be extremely persuasive. With the domination of the behavioral perspective, there also came skepticism, including one skeptic by the name of Edward C. Tolman. Tolman later introduced cognitive psychology, which is still a staple in modern day psychology. John B. Watson did not have the most ideal childhood. Perhaps this is why he later went on to become the mouthpiece for the movement that came to be called behaviorism (Goodwin, 2008, p. #338). He was born in 1878, just outside of Greenville, South Carolina. His father was a farmer with severe issues, such as a lcoholism, adultery, and anger. His mother was an extremely religious woman who pushed a future in the faith onto Watson. Although Watson was a bright young man, entering Furman University at the age of 16, he was well known as a troublemaker. Watson went on to earn his master’s degree in 1900 before entering the University of Chicago. His intention was to study philosophy and psychology but later decided to focus on functionalist psychology. Watson had a profound interest in animals and found himself extremely comfortable in studying their behaviors, rather than those of human subjects. Watson’s doctoral dissertation, codirected by Henry Donaldson and James Angell, was a study of the relationship between cortical development and learning in young white rats (Goodwin, 2008, p. #338). White rats were thought to be incapable of â€Å"associative learning† because their brains contained very few myelinated axons. Watson’s studies later proved this to be wrong, in fact, proving that a white rat’s ability to form associations improved in their fourth week of life, as opposed to the first few weeks. Watson later published his results as Animal Education: An Experimental Study of the Psychical Development of the White Rat, Correlated with the Growth of Its Nervous System. This publication earned him his doctorate and the opportunity to remain at the University of Chicago as an instructor. Burrhus Frederick Skinner’s upbringing was a little different than that of John B. Watson. Skinner was born in 1904 in Susquehanna, Pennsylvania. His father was a successful lawyer and his mother was a homemaker, together they were a very image conscious married couple who often worried about what others thought. Skinner was a very intelligent individual and an independent thinker. He questioned anything that was not supported with sound evidence. His high school principle strongly recommend ed him to New York’s Hamilton College, stating that Skinner was â€Å"passionately fond of arguing with his teachers. He is quite a reader and although I do not think he actually supposes himself wiser than his teachers, I have found him [to give] that impression†¦Ã¢â‚¬  (as cited in Goodwin, 2008, p. #383). After his initial unhappiness with Hamilton’s atmosphere, Skinner realized that he had a passion for creative writing. Skinner decided to take a year off after his graduation to just write. He moved back home with his parents and later referred to this time as his â€Å"dark year†. Skinner’s parents were concerned about what people thought of their son moving back home without a job, while Skinner was concerned with the pressure of his parents expecting him to be productive in this year. In this year, Skinner read a number of articles and became intrigued with behaviorism. This intrigue motivated him to pursue graduate studies in psychology at Harvard. As Skinner moved up the ladder, from a graduate student to a university fellow, his attitude toward authority never changed. Not impressed by the work of E.G. Boring, he referred to Boring’s perception course as â€Å"simply painful† and lamented that Boring spent three entire lectures explaining a single visual illusion (Goodwin, 2008, p. #384). Skinner published his first book in 1938, The Behavior of Organisms, which summarized his years of research at Harvard. He later returned to Harvard, in 1948, and remained active until his death in 1990. Edward C. Tolman was born in 1886 in a suburb of Boston, Massachusetts. Tolman came from a very stable and healthy family. His father was a successful business executive, while his mother provided a solid moral foundation for the family. Tolman was extremely intelligent and talented, graduating from the Massachusetts Institute of Technology (MIT) in 1911 with a degree in electrochemistry. There were two reasons why Tolman decided to stray from a career in the field of electrochemistry. The first reason was the competition that would ensue with his brother, Richard Tolman, who later contributed to the development of the atomic bomb during World War II (Goodwin, 2008, p. #364). The second reason lies in Tolman’s discovery of William James, often referred to as the father of American psychology. Following his graduation from MIT, Tolman enrolled in two summer courses at Harvard. The first was a philosophy course and the second was an introductory course in psychology. Robert Yerkes was the professor for this psychology course. Not only the professor, but also the reason Tolman was sold on psychology and decided to enter graduate school at Harvard. Tolman went on to earn his doctorate degree in 1915 from H arvard. Watson’s publication, Behavior: An Introduction to Comparative Psychology, made Tolman see behaviorism as an attractive alternative to the traditional introspective psychology he was encountering in Hugo Munsterberg’s laboratory (Goodwin, 2008, p. #364). Edward Holt was a major influence on the Tolman’s beliefs. Holt believed that Watsonian behaviorism was too reductionistic and argued that behavior should be defined more broadly as actions that serve some purpose (Goodwin, 2008). Great deals of Holt’s beliefs were adopted by Tolman and later became the core of Tolman’s theory of learning. Later on, Tolman would be launched down the behavioristic slope after being given the opportunity to develop a new course and remembering Yerks’ course and Watson’s textbook. With such different backgrounds growing up, these three men definitely have similarities they share as well. Watson, Skinner, and Tolman each have their own connection to the behaviorist perspective in one way or another. Watson and Skinner each believe that an individual’s behavior can be conditioned in certain ways. For example, Watson was a firm believer in classical conditioning, while Skinner developed operant conditioning. After extensive research on animals, particularly rats, Watson performed an experiment on Little Albert to test his theory or classical conditioning. Aside from the ethical issues of experimenting on an infant, Watson was successful in proving his theory correct. Little Albert was classically conditioned to fear, not only the white furry rat, but anything else that resembled the rat in any way. This fear was elicited by the loud noise that was associated with the presence of the furry rat. Skinner’s beliefs differed in the sense that he believed an individual’s behavior is influenced primarily by the consequence following that particular behavior. For example, if it is a negative effect the behavior is less likely to occur again. If it is a positive consequence that follows that behavior, the chances of the behavior repeating are more likely. This is the premise of operant conditioning. Tolman’s trademark was little different because he introduced the cognitive theory to the world of psychology. Tolman too performed experiments on rats and their ability to run through complex mazes in order to gain a different type of understanding on how their brains register and use the knowledge they obtain. Repetition of the same routines everyday are overlooked. It is only when something is sought after in these routines that an individual or animal is able to recognize what they have previously learned. This is what Tolman believed to be a type of cognitive learning. Although primary behaviorism therapy is not popular today, behaviorism has been incorporated with cognitive therapy to develop cognitive behavioral therapy. Cognitive behavioral therapy is a form of treatment that focuses on examining the relationships between thoughts, feelings, and behaviors (Duckworth, MD & Freedman, MD, 2012, p. #1). This is a very popular type of therapy today, especially with treating schizophrenia, post-traumatic stress disorder, and also different types of anxiety disorders. One of the greatest benefits of cognitive behavioral therapy is the ability to allow the patient to work with the clinician in developing the most useful treatment plan. It is almost like an active intervention where the patie nt is a little more active in the planning of treatment options. This can sometimes require the patient to do different types of homework on their own. Watson, Skinner, and Tolman have definitely opened up the psychology world to so many different perspectives and theories. Although each perspective may have its different flaws or drawbacks, together they contribute what each lacks when standing alone. Without Watsons initial research, Skinner may not have been influenced to theorize such perspectives as operant conditioning. In turn, Tolman may have not had the chance to develop what we now call cognitive behavioral therapy. Each stepping stone has added a little more history to the world of psychology to make it what it is today. These are just three of the men that can be attributed for the extensive time and research responsible for this said history. References Goodwin, C. J. (2008).

An ecosystem as a community Essay

Introduction An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment,[4] they can be of any size but usually encompass specific, limited spaces[5] (although some scientists say that the entire planet is an ecosystem).[6] Energy, water, nitrogen and soil minerals are other essential abiotic components of an ecosystem. The energy that flows through ecosystems is obtained primarily from the sun. It generally enters the system through photosynthesis, a process that also captures carbonfrom the atmosphere. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter,decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.[7] Ecosystems are controlled both by external and internal factors. External factors such as climate, the parent material which forms the soil and topography, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem.[8] Other external factors include time and potential biota. Ecosystems are dynamic entities—invariably, they are subject to periodic disturbances and are in the process of recovering from some past disturbance.[9] Ecosystems in similar environments that are located in different parts of the world can have very different characteristics simply because they contain different species.[8] Theintroduction of non-native species can cause substantial shifts in ecosystem function. Internal factors not only control ecosystem processes but are also controlled by them and are often subject to feedback loops.[8] While the resource inputs are generally controlled by external processes like climate and parent material, the  availability of these resources within the ecosystem is controlled by internal factors like decomposition, root competition or shading.[8] Other internal factors include disturbance, succession and the types of species present. Although humans exist and operate within ecosystems, their cumulative effects are large enough to influence external factors like climate.[8] Biodiversity affects ecosystem function, as do the processes of disturbance and succession. Ecosystems provide a variety of goods and services upon which people depend; the principles of ecosystem management suggest that rather than managing individual species,natural resources should be managed at the level of the ecosystem itself. Classifying ecosystems into ecologically homogeneous units is an important step towards effective ecosystem management, but there is no single, agreed-upon way to do this. Classification Classifying ecosystems into ecologically homogeneous units is an important step towards effective ecosystem management.[42] A variety of systems exist, based on vegetation cover, remote sensing, and bioclimatic classification systems.[42] American geographer Robert Bailey defines a hierarchy of ecosystem units ranging from microecosystems (individual homogeneous sites, on the order of 10 square kilometres (4 sq mi) in area), through mesoecosystems (landscape mosaics, on the order of 1,000 square kilometres (400 sq mi)) to macroecosystems (ecoregions, on the order of 100,000 square kilometres (40,000 sq mi)).[43] Bailey outlined five different methods for identifying ecosystems: gestalt (â€Å"a whole that is not derived through considerable of its parts†), in which regions are recognized and boundaries drawn intuitively; a map overlay system where different layers like geology, landforms and soil types are overlain to identify ecosystems; multivariate clustering of site attrib utes; digital image processing of remotely sensed data grouping areas based on their appearance or other spectral properties; or by a â€Å"controlling factors method† where a subset of factors (like soils, climate, vegetation physiognomy or the distribution of plant or animal species) are selected from a large array of possible ones are used to delineate ecosystems.[44] In contrast with  Bailey’s methodology, Puerto Rico ecologist Ariel Lugo and coauthors identified ten characteristics of an effective classification system: that it be based on georeferenced, quantitative data; that it should minimize subjectivity and explicitly identify criteria and assumptions; that it should be structured around the factors that drive ecosystem processes; that it should reflect the hierarchical nature of ecosystems; that it should be flexible enough to conform to the various scales at which ecosystem management operates; that it should be tied to reliable measures of climate so that it can â€Å"anticipat[e] global climate change; that it be applicable worldwide; that it should be validated against independent data; that it take into account the sometimes complex relationship between climate, vegetation and ecosystem functioning; and that it should be able to adapt and improve as new data become available†.[42] Types Aquatic ecosystem An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems andfreshwater ecosystems.[1] Marine ecosystems: cover approximately 71% of the Earth’s surface and contain approximately 97% of the planet’s water. They generate 32% of the world’s net primary production.[1] They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially salts, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. Seawater has an average salinity of 35 parts per thousand (ppt) of water. Actual salinity varies among different marine ecosystems.[2] Large marine ecosystems: (LMEs) are regions of the world’s oceans, encompassing coastal areas from river basins and estuaries to the seaward boundaries of continental shelves and the outer margins of the major ocean current systems. They are relatively large regions on the order of 200,000 km ² or greater, characterized by distinct bathymetry, hydrography, productivity, and trophically dependent populations. The system of LMEs has been developed by the US National Oceanic and Atmospheric  Administration (NOAA) to identify areas of the oceans for conservation purposes. The objective is to use the LME concept as a tool for enabling ecosystem-based management to provide a collaborative approach to management of resources within ecologically-bounded transnational areas. This will be done in an international context and consistent with customary international law as reflected in 1982 UN Convention on the Law of the Sea.[1] LME-based conservation is based on recognition that the world’s coastal ocean waters are degraded by unsustainable fishing practices, habitat degradation, eutrophication, toxic pollution, aerosol contamination, and emerging diseases, and that positive actions to mitigate these threats require coordinated actions by governments and civil society to recover depleted fish populations, restore degraded habitats and reduce coastal pollution. Although the LMEs cover only the continental margins and not the deep oceans and oceanic islands, the 64 LMEs produce 95% of the world’s annual marine fishery biomassyields. Most of the global ocean pollution, overexploitation, and coastal habitat alteration occur within their waters. NOAA has conducted studies of principal driving forces affecting changes in biomass yields for 33 of t he 64 LMEs, which have been peer-reviewed and published in ten volumes.[2] Freshwater ecosystems: are a subset of Earth’s aquatic ecosystems. They include lakes and ponds, rivers, streams and springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration, and vegetation. Freshwater ecosystems can be divided into lentic ecosystems (still water) and lotic ecosystems (flowing water). Limnology (and its branch freshwater biology) is a study about freshwater ecosystems. It is a part of hydrobiology. Original efforts to understand and monitor freshwater ecosystems were spurred on by threats to human health (ex. Cholera outbreaks due to sewage contamination). Early monitoring focussed on chemical indicators, then bacteria, and finally algae, fungi and protozoa. A new type of monitoring involves differing groups of organisms (macroinvertebrates, macrophytes and fish) and the stream conditions associated with them. Current biomonitering techniques focus mainly on community structure or biochemical oxygen demand. Responses  are measured by behavioural changes, altered rates of growth, reproduction or mortality. Macroinvertebrates are most often used in these models because of well known taxonomy, ease of collection, sensitivity to a range of stressors, and their overall value to the ecosystem. Most of these measurements are difficult to extrapolate on a large scale however. The use of reference sites is common when assessing what a healthy freshwater ecosystem should â€Å"look like†. Reference sites are easier to reconstruct in standing water than moving water. Preserved indicators such as diatom valves, macrophyte pollen, insect chitin and fish scales can be used to establish a reference ecosystem representative of a time before lar ge scale human disturbance. Common chemical stresses on freshwater ecosystem health include acidification, eutrophication and copper and pesticide contamination. Lake ecosystems :The ecosystem of a lake includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions.[1] Lake ecosystems are a prime examples of lentic ecosystems. Lentic refers to standing or relatively still water, from the Latin lentus, which means sluggish. Lentic waters range from ponds to lakes to wetlands, and much of this article applies to lentic ecosystems in general. Lentic ecosystems can be compared withlotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two fields form the more general study area of freshwater or aquatic ecology. Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1740 m.[2] The general distinction between pools/ponds and lakes is vague, but Brown[1] states that ponds and pools have their entire bottom surfaces exposed to light, while lakes do not. In addition, some lakes become seasonally stratified (discussed in more detail below.) Ponds and pools have two regions: the pelagic open water zone, and the benthic zone, which comprises the bottom and shore regions. Since lakes have deep bottom regions not exposed to light, these systems have an additional zone, the profundal.[3] These three areas can have very different abiotic conditions and, hence, host species that are specifically adapted to live there.[1] River ecosystem The ecosystem of a river is the river viewed as a system operating in its natural environment, and includes biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions.[1][2] River ecosystems are prime examples of lotic ecosystems. Lotic refers to flowing water, from the Latin lotus, washed. Lotic waters range from springs only a few centimeters wide to major rivers kilometers in width.[3] Much of this article applies to lotic ecosystems in general, including related lotic systems such as streams and springs. Lotic ecosystems can be contrasted with lentic ecosystems, which involve relatively still terrestrial waters such as lakes and ponds. Together, these two fields form the more general study area of freshwater or aquatic ecology. The following unifying characteristics make the ecology of running waters unique from that of other aquatic habitats.[4] Flow is unidirectional. There is a state of continuous physical change. There is a high degree of spatial and temporal heterogeneity at all scales (microhabitats). Variability between lotic systems is quite high.  The biota is specialized to live with flow conditions. Wetland ECOSYSTEM A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem.[2] Primarily, the factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetationthat is adapted to its unique soil conditions. Wetlands consist primarily of hydric soil, which supports aquatic plants.[3][4] The water found in wetlands can be saltwater, freshwater, or brackish.[4] Main wetland types include swamps, marshes, bogs and fens.[5]Sub-types include mangrove, carr, pocosin, and varzea. Wetlands play a number of roles in the environment, principally water purification, flood control, and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and  animal life.[6] Wetlands occur naturally on every continent except Antarctica.[7] They can also be constructed artificially as a water management tool, which may play a role in the developing field of water-sensitive urban design. The largest wetlands in the world include the Amazon River basin and the West Siberian Plain.[8] Another large wetland is the Pantanal, which straddles Brazil, Bolivia, and Paraguay in South America.[9] The UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth. International conservation efforts are being used in conjunction with the development of rapid assessment tools to inform people about wetland issues. Terrestrial ecosystem A terrestrial ecosystem is an ecosystem found only on landforms. Six primary terrestrial ecosystems exist: tundra, taiga, temperate deciduous forest, tropical rain forest,grassland and desert.[1] A community of organisms and their environment that occurs on the land masses of continents and islands. Terrestrial ecosystems are distinguished from aquatic ecosystems by the lower availability of water and the consequent importance of water as a limiting factor. Terrestrial ecosystems are characterized by greater temperature fluctuations on both a diurnal and seasonal basis than occur in aquatic ecosystems in similar climates. The availability of light is greater in terrestrial ecosystems than in aquatic ecosystems because the atmosphere is more transparent in land than in water. Gases are more available in terrestrial ecosystems than in aquatic ecosystems. Those gases include carbon dioxide that serves as a substrate for photosynthesis, oxygen that serves as a substrate in aerobic respiration, and nitrogen that serves as a substrate for nitrogen fixation. Terrestrial environments are segmented into a subterranean portion from which most water and ions are obtained, and an atmospheric portion from which gases are obtained and where the physical energy of light is transformed into the organic energy of carbon-carbon bonds through the process of photosynthesis. Terrestrial ecosystems occupy 55,660,000 mi2 (144,150,000 km2), or 28.2%, of Earth’s surface. Although they are comparatively recent in the history of life (the first terrestrial organisms appeared in the Silurian Period, about 425 million years ago) and  occupy a much smaller portion of Earth’s surface than marine ecosystems, terrestrial ecosystems have been a major site of adaptive radiation of both plants and animals. Major plant taxa in terrestrial ecosystems are members of the division Magnoliophyta (flowering plants), of which there are about 275,000 species, and the division Pinophyta (conifers), of which there are about 500 species. Members of the division Bryophyta (mosses and liverworts), of which there are about 24,000 species, are also important in some terrestrial ecosystems. Major animal taxa in terrestrial ecosystems include the classes Insecta (insects) with about 900,000 species, Aves (birds) with 8500 species, and Mammalia (mammals) with approximately 4100 species. Organisms in terrestrial ecosystems have adaptations that allow them to obtain water when the entire body is no longer bathed in that fluid, means of transporting the water from limited sites of acquisition to the rest of the body, and means of preventing the evaporation of water from body surfaces. They also have traits that provide body support in the atmosphere, a much less buoyant medium than water, and other traits t hat render them capable of withstanding the extremes of temperature, wind, and humidity that characterize terrestrial ecosystems. Finally, the organisms in terrestrial ecosystems have evolved many methods of transporting gametes in environments where fluid flow is much less effective as a transport medium. The organisms in terrestrial ecosystems are integrated into a functional unit by specific, dynamic relationships due to the coupled processes of energy and chemical flow. Those relationships can be summarized by schematic diagrams of trophic webs, which place organisms according to their feeding relationships. The base of the food web is occupied by green plants, which are the only organisms capable of utilizing the energy of the Sun and inorganic nutrients obtained from the soil to produce organic molecules. Terrestrial food webs can be broken into two segments based on the status of the plant material that enters them. Grazing food webs are associated with the consumption of living plant material by herbivores. Detritus food webs are associated with the consumption of dead plant material by detritivores. Th e relative importance of those two types of food webs varies considerably in different types of terrestrial ecosystems. Grazing food webs are more important in grasslands, where over half of net primary productivity may be consumed by herbivores. Detritus food webs are more important in forests, where less  than 5% of net primary productivity may be consumed by herbivores. There is one type of extensive terrestrial ecosystem due solely to human activities and eight types that are natural ecosystems. Those natural ecosystems reflect the variation of precipitation and temperature over Earth’s surface. The smallest land areas are occupied by tundra and temperate grassland ecosystems, and the largest land area is occupied by tropical forest. The most productive ecosystems are temperate and tropical forests, and the least productive are deserts and tundras. Cultivated lands, which together with grasslands and savannas utilized for grazing are referred to as agroecosystems, are of intermediate extent and productivity. Because of both their areal extent and their high average productivity, tropical forests are the most productive of all terrestrial ecosystems, contributing 45% of total estimated net primary productivity on land. CAUSES OF DESTRUCTION The degradation of ecosystems is an environmental problem that diminishes the capacity of species to survive. This degradation occurs in different ways and is manifested in a reduction in the richness of the ecosystems as well as their biological diversity, and in the goods and services they can offer, thereby affecting indigenous and/or migratory species. The degradation of ecosystems due to overexploitation of their resources, though serving a short-term economic goal, has had direct negative effects on social welfare in the medium and long terms. As long as the ecosystem is not degraded, it represents a source of wealth for society, hence the importance of keeping it in good condition. One of the main causes that contributes to the degradation of ecosystems is the deforestation due to the advance of the agriculture frontier and inappropriate forest exploitation. More lands are deforested for commercial agriculture and live-stock rearing, and due to overexploitation of forest for wood and energy. In Nicaragua deforestation rates reach over 150,000 hectares per year and in Costa Rica over 18,500 hectares per year. At a lower scale, another problem is the uncontrolled fires used to prepare land for agricultural activities or to remove forest for the development of stock rearing areas. This practice eliminates the organic covering of the land, making it more susceptible to erosion by both  wind and water. In addition, the fires cause health problems and detract from the aesthetic value of the landscape. Accidental or natural fires are another case in point. They affect areas of natural forest. In the Upala and Los Chiles cantons, in Costa Rica, some 10,000 hectares were burned between 1998 and 1999. This problem is even more serious in the Nicaraguan territory of the basin. Equipment is lacking and communities need to be organized to control t hese fires as one of the main barriers to the burning of large areas. The construction of roads without proper drainage measures or in territories subject to penetration and settlement are high-stress factors for ecosystems, especially those which are highly fragile as a result of their weather conditions and the nature of their soil and water. Mining and the extraction of construction materials without taking measures to cushion the impact cause drastic changes in the natural landscape while degrading its valuable ecosystems. Wetlands are very fragile ecosystems that are being severely affected, causing a reduction in the number and diversity of the species of terrestrial flora, birds, reptiles, mammals, fish, and crustaceans. This problem results from excessive exploitation of wildlife species either to feed the population, to trade their furs, or to trade live species, and from sedimentation, which causes changes in water quality, thereby significantly affecting the reproduction of aquatic species that live and/or reproduce in the wetlands. The SJRB wetlands are very valuable ecosystems, which regulate the hydrological cycle and provide food and shelter for hundreds of species, including large quantities of migratory birds. One major cause of the deterioration of this ecosystem is the draining of wide areas of wetlands to give access to agricultural zones or human settlements. Aerial photographs of the Caà ±o Negro sector show how the pools of water have diminished over time, due in part to the drainage of wetlands for agricultural purposes and to the sedimentation occurring in recent years in the basin. Owing to the deterioration of these areas and the pressure of the neighboring communities on the use of the natural resources of the wetlands, it is necessary to draw up management plans to outline the socioeconomic characteristics of users and guidelines for usage, since people are highly dependent on these resources for their survival. A large portion of the ecological problems of the wetlands is due to ignorance of their benefits. The use of inappropriate fishing techniques endangers the  existence of certain species, altering the food chain of aquatic fauna and consequently deteriorating the aquatic ecosystems. This is the case of the bull shark that is now hard to find in Lake Nicaragua or in the San Juan River. In some cases, the introduction of exotic species endangers the existence of indigenous species with a high cultural value. Such is the case of the guapote, whose numbers are being reduced by the introduction of tilapias. The deterioration of ecosystems is exacerbated by the lack of an institutional presence in the territory, be it for technical or economic reasons, or a combination of both. As a result, laws on the regulation and control of natural resource use are not enforced. The participation of civil society in controlling the use and exploitation of natural resources is limited and, in many cases, very timid or markedly apathetic. One aspect that has not been evaluated in the degradation of the ecosystems is the incidence of different phenomena on these systems. The geographic location of the SJRB and the various geographic accidents encountered there render it susceptible to the impact of various events of this kind. In the SJRB there are a number of active volcanoes, which spew gas and ash causing damage to the plant life, the soil, polluting water bodies, and causing severe damage to entire populations. These volcanoes include the Masaya, the Maderas, and the Irazà º. Another natural phenomenon in the SJRB is landslides which, though located in specific areas, cause damage to the ecosystems, the soil, pollute water bodies, damage infrastructure and entire settlements. The Maderas volcano on the island Ometepe is a case in point. Similarly, during the last century, the SJRB has suffered the destructive effects of at least three hurricanes which, with their heavy rainfall, cause flooding damaging ecosystems, eroding soil, diverting river courses, causing severe damage to infrastructure and entire populations, resulting in the loss of human lives. Other natural phenomena that have caused damage to the ecosystems of the SJRB are the droughts that have occurred as a result of the El Nià ±o and seismic activity, which have changed river courses, particularly in the case of the Tipitapa River that provided a permanent connection between the Managua and Nicaragua lakes. As a result of an earthquake during the last century, the riverbed rose in a certain sector cutting off the existing connection between the two lakes. The degradation of the ecosystems makes the economic and social infrastructure of the SJRB more vulnerable and  increases the potential impact on the population. This vulnerability is reflected in shorter periods between the occurrence of floods or droughts and the soil becomes more unstable. Possible solutions to the problem of deterioration of the ecosystems include developing formal and informal environmental education programs to make farmers more aware of their actions; increasing enforcement of the existing l egislation; promoting proper natural resource management; and promoting the organization of grassroots groups to control burning from the outset. To prevent or mitigate the damage caused by extreme conditions, such as flooding and droughts and other effects of natural phenomena, it is necessary to set up and early warning system about possible swelling of water bodies and to monitor hydrometeorological behavior. It is also necessary to set up a seismographic network to monitor the behavior of volcanoes and tectonic faults. Similarly, social organization is necessary to design and test emergency plans for natural phenomena, to reduce the damage they cause. Institutions responsible for the control and regulation of natural resource use must be strengthened, both technically and economically, and be given the means for their mobilization. This would enable them to have a real presence in the territory. It is also necessary to create mechanisms for enforcing the current legislation. Conservation practices to save ecosystem Environmental protection is a practice of protecting the natural environment on individual, organizational or governmental levels, for the benefit of both the natural environment and humans. Due to the pressures of population and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, activity of environmental movements has created awareness of the various environmental issues. There is no agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized. Academic institutions now offer courses, such as environmental studies, environmental management and environmental engineering, that teach the history and methods of environment protection. Protection of the environment is needed due to various human  activities. Waste production, air pollution, and loss of biodiversity (resulting from the introduction of invasive species and species extinction) are some of the issues related to environmental protection. Environmental protection is influenced by three interwoven factors: environmental legislation, ethics and education. Each of these factors plays its part in influencing national-level environmental decisions and personal-level environmental values and behaviors. For environmental protection to become a reality, it is important for societies to develop each of these areas that, together, will inform and drive environmental decisions.[1] How to Save Our Ecosystem Instructions Educate yourself about your local environment. Starting small and learning about the plants and animals in your immediate surroundings will give you an appreciation for the enormous variety of ecosystems on our earth. It will also help you understand how you fit into your natural surroundings and get you thinking about the effects of your actions. When you flush the toilet, where does your water go? When you wash the car and soap runs off into the street, what does that soap go on to affect? What animals do you disturb by replacing native vegetation with nonnative landscaping? Asking yourself these questions is a one of the first steps to reducing your carbon footprint. 2  Find an activist group in your area with a cause you support. It can be a local issue, such as preserving open space in your community, or a more widespread issue, like passing legislation that requires cars to produce fewer greenhouse gas emissions. Being part of a group allows you to meet like-minded people and work toward a common environmental goal.

Everything you buy has a product life cycle, or a history of how it was produced using what materials. When possible, reduce the impact of your purchase by buying products that are made locally and/or are manufactured from recycled materials. 4  Eat local, organic food. Local food travels less distance from farm to your table, which means that it has a lower carbon footprint, is fresher, and supports your community’s farmers. Organic food is produced without the use of chemical pesticides or fertilizers, and without genetically modified crops. Chemical pesticides and fertilizers can get into the natural environment and harm existing plants and animals; genetically modified crops reduce biodiversity by encouraging a monoculture farm. 5  Travel wisely to decrease your carbon footprint. Use alternative methods of transportation whenever feasible—walk to the store, ride your bike to work, take public transportation downtown. When you do drive, accelerate and decelerate gradually to conserve gas. Also, make sure that your tires are properly inflated and that the emissions system on your vehicle is well maintained.

Violence in Schools essays

Violence in Schools essays A large number of Australian schools have been taking actions to prevent violence in schools. In the last ten years in American schools there has been an increase in school shootings, where students have opened fire on their own classmates. Is Australia headed down the same path and if so what are we doing to prevent these scary incidents from occurring? In America a range of measures have been taken to stop violence in schools. The action in the fight to prevent shootings in schools has been so large that school budgets in America have used to install metal detectors and hire security staff, instead of textbooks and educational resources. It was estimated that in the mid nineties over 100,000 students carried guns to school in America alone. There were 55 students killed in 1992 by fellow classmates and the mid nineties the number had risen to an all time high. Then America started to take action. Today however around twenty students are killed in American schools each year. So we may ask why do these events still occur, even after large sums of money have been spent to try and stop them? It is more than likely due to Americas strong gun movement and high crime levels. In America the laws for having guns are not as rigid and therefore it is extremely easy for youth to get their hands on illegal lethal firearms. However we are yet to see these kinds of mass school shootings in Australia but whose to say it wont happen. What actions have been taken in Australia and what are we doing to prevent such a tragedy? In South Australia and Melbourne a project called CNC (Creating New Choices) has been developed in the effort to stop violence in the education area. It is the pioneer of its kind and supported by Berry Street Child and Family Services. They are one of Victoria's largest independent, non-government welfare organizations. The project works with 2-3 schools at one time. It helps by making p ...

Gunpowder Facts, History and Description

Gunpowder Facts, History and Description Gunpowder or black powder is of great historical importance in chemistry. Although it can explode, its principal use is as a propellant. Gunpowder was invented by Chinese alchemists in the 9th century. Originally, it was made by mixing elemental sulfur, charcoal, and saltpeter (potassium nitrate). The charcoal traditionally came from the willow tree, but grapevine, hazel, elder, laurel, and pine cones have all been used. Charcoal is not the only fuel that can be used. Sugar is used instead in many pyrotechnic applications. When the ingredients were carefully ground together, the end result was a powder that was called serpentine. The ingredients tended to require remixing prior to use, so making gunpowder was very dangerous. People who made gunpowder would sometimes add water, wine, or another liquid to reduce this hazard since a single spark could result in a smoky fire. Once the serpentine was mixed with a liquid, it could be pushed through a screen to make small pellets, which were then allowed to dry. How Gunpowder Works To summarize, black powder consists of a fuel (charcoal or sugar) and an oxidizer (saltpeter or niter), and sulfur, to allow for a stable reaction. The carbon from the charcoal plus oxygen forms carbon dioxide and energy. The reaction would be slow, like a wood fire, except for the oxidizing agent. Carbon in a fire must draw oxygen from the air. Saltpeter provides extra oxygen. Potassium nitrate, sulfur, and carbon react together to form nitrogen and carbon dioxide gases and potassium sulfide. The expanding gases, nitrogen and carbon dioxide, provide the propelling action. Gunpowder tends to produce a lot of smoke, which can impair vision on a battlefield or reduce the visibility of fireworks. Changing the ratio of the ingredients affects the rate at which the gunpowder burns and the amount of smoke that is produced. Difference Between Gunpowder and Black Powder While black powder and traditional gunpowder may both be used in firearms, the term black powder was introduced in the late 19th century in the United States to distinguish newer formulations from traditional gunpowder. Black powder produces less smoke than the original gunpowder formula. Its worth noting early black powder was actually off-white or tan in color, not black! Charcoal Versus Carbon in Gunpowder Pure amorphous carbon is not used in black powder. Charcoal, while it contains carbon, also contains cellulose from incomplete combustion of wood. This gives charcoal a relatively low ignition temperature. Black powder made from pure carbon would barely burn. Gunpowder Composition There is no single recipe for gunpowder. This is because varying the ratio of the ingredients produces different effects. Powder used in firearms needs to burn at a fast rate to quickly accelerate a projectile. A formulation used as a rocket propellant, on the other hand, needs to burn more slowly because it accelerates a body over a long period of time. Cannon, like rockets, use a powder with a slower burn rate. In 1879, the French prepared gunpowder using 75% saltpeter, 12.5% sulfur, and 12.5% charcoal. The same year, the English used gunpowder made from 75% saltpeter, 15% charcoal, and 10% sulfur. One rocket formula consisted of 62.4% saltpeter, 23.2% charcoal, and 14.4% sulfur. Gunpowder Invention Historians believe gunpowder originated in China. Originally, it was used as an incendiary. Later, it found use as a propellant and explosive. It remains unclear when, exactly, gunpowder made its way to Europe. Basically, this is because records describing the use of gunpowder are difficult to interpret. A weapon that produced smoke might have used gunpowder or could have used some other formulation. The formulas that came into use in Europe closely matched those used in China, suggesting the technology was introduced after it had already been developed. Sources Agrawal, Jai Prakash (2010).

Diabetes Mellitus Research Paper Example | Topics and Well Written Essays - 750 words

Diabetes Mellitus - Research Paper Example It is worth beginning by describing the role of insulin when the body is functioning normally. When a person eats, the levels of glucose in their blood increase, as foods, and especially carbohydrates, are digested. Glucose is the main source of energy in the body, but must undergo metabolic processes in cells to produce this energy. Among the body’s homeostatic systems – the mechanisms for keeping conditions in the body within a given, safe range – is a system for controlling insulin levels, by removing or adding it from the bloodstream. Key to this process is the hormone insulin, produced by the beta cells in the islets of Langerhans in the pancreas. When the blood glucose level rises after eating, the pancreas secretes insulin into the blood. This stimulates the cells of the liver to absorb the glucose from the blood, thus reducing the level of glucose in the blood. Diabetes takes two main forms, generally known as Type 1, or insulin dependent Diabetes Mellitus and Type 2, or non-insulin dependent Diabetes Mellitus. Type 1 Diabetes accounts for around 5-10% of cases; Type 2 for around 90-95% of cases. Type 1 Diabetes is an autoimmune disease. Such diseases occur when the mechanisms of the immune system – the body’s defences for dealing with infection and disease - damage parts of the body. This is a failure by the body to recognise some cells as parts of itself. In the case of Type 1 Diabetes, the body destroys its own beta cells in the pancreas – where insulin is produced. Therefore, when the glucose level in the blood rises, cells do not have sufficient energy for metabolism, which can leave the sufferer in a very dangerous situation. Suffers of Type 1 diabetes need to take insulin injections every day, in order to maintain normal blood glucose levels. The first insulin injections became available in 1921. Before this, pe ople who suffered from Type 1 Diabetes
