The molten rock that erupts from the volcano forms a hill or mountain around the vent. The lava may flow out as a viscous liquid or it may explode from the vent as solid or liquid particles. Kinds of Volcanic Materials Three basic materials that may erupt from a volcano are; 1. lava, 2. rock fragments, and 3. gas. Lava Lava is the name for magma that has been released onto the Earths surface. When lava comes to the Earths surface, it is red hot and may have temperatures of more than 2012 degrees Fahrenheit. Fluid lava flows swiftly down a volcanos slopes. Sticky lava flows more slowly. As the lava cools, it may harden into many different formations. Highly fluid lava hardens into smooth, folded sheets of rock called pahoehoe. Stickier lava cools into rough, jagged sheets of rock called aa. Pahoehoe and aa cover large areas of Hawaii, where the terms originated. The stickiest lava forms flows of boulders and rubble called block flows. It may also form mounds of lava called domes. Other lava formations are spatter cones and lava tubes. Spatter cones are steep hills that can get up to 100 feet high. They build up from the spatter of geyser-like eruptions of thick lava. Lava tubes are tunnels formed from fluid lava. As the lava flows, its exterior covering cools and hardens. But the lava below continues to flow. After the flowing lava drains away, it leaves a tunnel. Rock Fragments Rock fragment are usually called tephra and are formed from sticky magma. This magma is so sticky that its gas can not easily escape when the magma approaches the surface or central vent. Finally, the trapped gas builds up so much pressure that it blasts the magma into fragments. Tephra consists of volcanic dust, volcanic ash, and volcanic bombs, (from smallest to largest size particle). Volcanic dust consists of particles less than one one-hundredth inch in diameter. Volcanic dust can be carried for great distances. In 1883, the eruption of Krakatau in Indonesia shot dust 17 miles into the air. The dust was carried around the Earth several times and produced brilliant red sunsets in many parts of the world. Some scientists assume large quantities of volcanic dust can affect the climate by reducing the amount of sunlight that reaches the Earth. Volcanic ash is made up of fragments less than one fifth inch in diameter. Nearly all volcanic ash falls to the surface and becomes welded together as rock called volcanic tuff. Sometimes, volcanic ash combines with water in a stream and forms a boiling mudflow. Mudflows may speeds up to 60 miles per hour and can be remarkably shattering. Volcanic bombs are large fragments. Most of them range from the size of a baseball to the size of a basketball. The largest bombs can measure up to more than four feet across and weigh up to 100 short tons. Small volcanic bombs are generally called cinders. Gas Gas pours out of volcanoes in large quantities during almost all eruptions. The gas is made up particularly of steam, but may also include carbon dioxide, nitrogen, sulfur dioxide, and other gases. Most of the steam comes from a volcanos magma, but some .uda74959f486ec7421c3c526594012a3c , .uda74959f486ec7421c3c526594012a3c .postImageUrl , .uda74959f486ec7421c3c526594012a3c .centered-text-area { min-height: 80px; position: relative; } .uda74959f486ec7421c3c526594012a3c , .uda74959f486ec7421c3c526594012a3c:hover , .uda74959f486ec7421c3c526594012a3c:visited , .uda74959f486ec7421c3c526594012a3c:active { border:0!important; } .uda74959f486ec7421c3c526594012a3c .clearfix:after { content: ""; display: table; clear: both; } .uda74959f486ec7421c3c526594012a3c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uda74959f486ec7421c3c526594012a3c:active , .uda74959f486ec7421c3c526594012a3c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uda74959f486ec7421c3c526594012a3c .centered-text-area { width: 100%; position: relative ; } .uda74959f486ec7421c3c526594012a3c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uda74959f486ec7421c3c526594012a3c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uda74959f486ec7421c3c526594012a3c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uda74959f486ec7421c3c526594012a3c:hover .ctaButton { background-color: #34495E!important; } .uda74959f486ec7421c3c526594012a3c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uda74959f486ec7421c3c526594012a3c .uda74959f486ec7421c3c526594012a3c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uda74959f486ec7421c3c526594012a3c:after { content: ""; display: block; clear: both; } READ: The Problems of Women's Labor Essaysteam may also be produced when rising magma heats water in the ground.

Effects of Television Violence essays

Effects of Television Violence essays What has the world come to these days? It often seems like everywhere one looks, violence rears its ugly head. We see it in the streets, back alleys, school, and even at home. In many peoples' living rooms there sits an outlet for violence that often goes unnoticed. It is the television, and the children who view it are often pulled into its realistic world of violence scenes with sometimes devastating results. A lot of research has gone into showing why television and the things that take place on the screen affect kids. Research shows that movies and TV are definitely a major source of violent behavior in children. The research proves time and time again that aggression and television viewing do go hand in hand. It is true that violence on the boob tube affects children. Some are try to find a solution for the problem; others ignore it and hope that the problem disappears. However, the facts are undeniable. The research has been done and the information has resulted out to one co nclusion: Television violence causes children to be violent and the effected for the rest of their lives. The research proved my hypothesis. Violent television viewing does affect children. The effects have been seen in a number of cases. The First case In Alabama, a nine-year-old boy received a bad report card from his teacher. He suggested sending the teacher poisoned candy as revenge as he had seen on television the night before. In California, a seven-year-old boy sprinkled ground-up glass into the lamb stew the family was to eat for dinner. When asked why he did it he replied that he wanted to see if the results would be the same in real life as they were on television (Howe 72). In New York, a boy broke into a basement. When the police caught him and asked him why he was wearing gloves he replied that he had learned on television the when you wear gloves you do not leave fingerprints. These are just a few cases I discovered of how te...

The Difference Between will and shall

The Difference Between will and shall The Difference Between will and shall The Difference Between will and shall By Maeve Maddox Reader Eric wonders about the uses of will and shall. When do you use will and shall? I know that [they] mean the same thing, but I would like to know when to use them in the correct grammatical sense. In modern English will and shall are helping verbs. They are used with other verbs, but lack conjugations of their own. Both are signs of the future tense. The old Walsh English Handbook that I used in high school gives this rule for forming the future: Use shall in the first person and will in the second and third persons for the simple future tense: I shall sing this afternoon. You will succeed. He will stay at home. My observations suggest that shall is rarely used by American speakers. The two words existed as separate verbs in Old English, the form of English spoken from 450-1150 C.E. The verb willan meant wish, be willing, be about to. The verb sculan (pronounced [shu-lan], had the meanings be obliged to, have to, must, be destined to, be supposed to. In modern usage traces of the old meanings persist for speakers who use both forms. Will can imply volition or intention, while shall can imply necessity: I will scale Mount Everest. (and no one can stop me!) You shall take the garbage out before you do anything else. (You have no choice, Junior!) A second element enters into the use of shall and will. As a matter of courtesy, a difference exists according to whether the verb is used with a first or second person subject. Which to use depends upon the relationship between speakers. Parents, teachers, employers, and staff sergeants are within their rights to tell someone You shall complete this assignment by 9 p.m. Such a construction offers no alternative. It is the same as saying You must complete this assignment. In speaking to an equal, however, the choice is left up to the other person: I shall drive to Tulsa today. You will follow on Tuesday. (Its still up to you.) Heres a frequently quoted joke that illustrates the consequences of using shall and will incorrectly: A foreign tourist was swimming in an English lake. Taken by cramps, he began to sink. He called out for help: Attention! Attention! I will drown and no one shall save me! Many people were within earshot, but, being well-brought up Englishmen and women, they honored his wishes and permitted him to drown. All of which is the short answer to Erics question. For the long answer, take a look at Fowler (Modern English Usage) and the OED. By the way, the verb will in the sense of bequeath derives from the noun will in the sense of wish. A will expresses the wishes of the person who writes it. The verb will (bequeath) does possess a complete conjugation. Want to improve your English in five minutes a day?

Autobiographical Statement - Essay Example ects of these on families at close quarters in my native land, I was determined to get a good education and get a slice of the good things in life for myself and my family. I was born in Sierra Leone, West Africa, one of the poorest countries of the world, but blessed to have a mother endowed with the grit and determination to make a better life for herself and her family. My mother brought the family over to the US in 1990 on a Certified Nursing Assistant paycheck. I was brought up by parents who are not educated, but who worked very hard and over time set up a small grocery store and restaurant. My mother’s life reminds me of a story she told me as a child about an ant who kept trying to carry a sugar cube to its den, and failed so many times but never gave up trying till it finally succeeded. I think the story is an inspiration to me even today and I go back to remembering my mother telling me the story and how it probably gave her strength in her periods of crisis. I am a single parent to two daughters. After the birth of my first daughter in 1999, I enrolled at St. Paul Community College in St. Paul, Minnesota. However, I was forced to drop out because I got no support or cooperation from my husband. I have had the misfortune of going through a traumatic relationship with an abusive and domineering husband, who would not allow me to finish college. After five years of physical, emotional and mental abuse, I decided to move to California to get away from him. In 2004, I put myself through Beauty College, completing the 1600 hours required by the state of California. In the same year, I passed my State Board Exam and became a licensed Cosmetologist. I got a job with Fantastic Sam for a couple of years while attending El Camino College in Torrance, California. In the year 2006, I plunged headlong into business. I opened my own hair salon in Gardena, CA. At first it was a wonderful feeling being my own boss and setting my own hours, working hard and studying

War Reply - Coursework Example t Britain revoke the order declaring the allowance of the interceptions and seizures of American ships, Britain initially did not and America declared war. (Nash, 2012) When Britain realized how seriously willing America was to go to war, Britain rescinded the very order that began this dispute. Therefore the initial cause for the war had been eliminated; negating the necessity of future warfare. The fact that Britain was so quick to react to avoid war, than, perhaps, other means other than war may have been possible. More so, even after the war ended, and treaty was signed, many of the issues of contention that had been so relevant during the course of the war were not even addressed. Several were not resolved until the following decade. If a just war is one that occurs because all other option for peaceful resolution was lost then this war would not seem to be just at all. It may have been entirely

Gamification of the Workplace Essay Example for Free

Gamification of the Workplace Essay The paper examines a new trend in workplace design called â€Å"gamification†. Gamification is defined as using concepts derived from video games and applying them in businesses to enhance motivation, raise productivity and lower turnover. The areas of effect discussed are motivation, cooperation, productivity and employee happiness. The text looks at which characteristics of video games make them so engaging and translates them into examples from the workplace. It presents real examples of companies that have implemented similar techniques. Gamification in the Workplace: A New Way to Think About Work Georgi Ivanov American University in Bulgaria The workforce of today is composed of young, talented and creative people, who despite their potential are less loyal and are always on the lookout for the job that better suits their qualification. As managers continue to search for ways to attract, motivate and keep them they ask themselves what makes this generation different from the previous. One of the things that separate us from other generations of workforce, video game addiction, has become increasingly relevant in the last decade. The college graduates that enter the labor market have played them since kids and consider them a hobby. The older generations learn about them as because of the app store which is a platform for easily accessible casual games. There is something in video games that makes people play them and create them and that something has made the video game industry the fastest growing entertainment industry today. With millions of people playing video games and investingmoney in their hobby, many companies implement video game concepts in an effort to make work more engaging, raise productivity and motivation and lower turnover. The process is known as â€Å"gamification†. To understand why managers would look to video and computer games of all things to improve the work life of their employees we have to understand what makes a video game so appealing to the modern employee and what part of that appeal is relevant to their productivity and satisfaction on their job. We know that some games have bigger audiences than prime time television shows, which means that these people prefer to do something, to be involved, than just sitting there and taking it in. In his book The Game of Work: How to Enjoy Work As Much As Play (1984) Charles Conrad leans on the fact that people will often work harder or even pay money to improve their performance outside of work. He outlines five principles that would transfer part of this to the business environment and empower employees – better scorekeeping, clearly defined goals, frequent feedback, better scorekeeping and consistent coaching. When the book was issued video games were not the object of the author’s discussion, however the concepts are present in today’s most popular video games. It is common have a score number in a corner of the screen showing how you are doing and every action you take changes that score. Taking this one step further is a ladder system that shows your score in comparison to other people’s score. With the popularity of video games today it is evident that people are respond very well to such a system. Through extension, if people are willing to devote so much time and energy into improving their game scores so they can climb the ladder and win intangible rewards, then, if they knew where they stood among their colleagues, they would be more motivated to do better. In her WSJ article Latest Game Theory: Mixing work and play (2011), Rachel Silverman gives a couple of examples of successful â€Å"gamification† of tasks. Live Ops Inc. runs a virtual call center. Th e company awards employees with virtual badges and points for keeping calls short and closing sales with leader boards that allow agents to compare their achievements. According to the vice president, since the system was implemented call time was reduced by 15% in some employees and sales have gone up by between 8% and 12%. I saw this in myself when I worked as a sales representative. When I joined the company it was evident who the top sales people were. Everybody’s numbers were available every day for everyone to see. From the first day that I saw that I imagined my name on the firs position of the day end report on the cash register screen just like I did on my computer screen while playing a favorite game of mine. It helped. I was always eager to keep track of my sales and strive to improve and my boss nurtured that friendly competitive atmosphere in which I thrived. This helped me in the beginning a lot because I did not feel intimidated by the more experienced members’ numbers. One of the most popular types of games today is the Massive Multiplayer Online Role-playing Game (MMORPG). The model is basically putting millions of players from all over the world in one universe and to let them progress in this world by developing their skills and handling challenges alone or in teams of other players who have diverse skill sets for different situations. There are player rankings and guild rankings. To climb up the ladder, players need to accomplish tasks or â€Å"quests† and apart from the regular points, they get badges, if they complete the quest not in an efficient or creative manner. As you play your character increases in strength by gaining levels. Each level requires more effort to achieve than the previous and the conditions that have to be met to advance are set in stone and they never change. You know ahead of time what you need in order to progress. Every task you’ve made has an effect on the completion and your progress is clearly visible. If we take this concept to the business world, we’d have a clear employee ranking system and a company ranking system. Each employee will aim for the top places on the scoreboard, but keeping in mind that success is only possible with cooperation. This would motivate employees not only to do their best but also to be more accommodating to newcomers because they know that the better the people in your team/ department are doing, the better they would do. We do have a leveling system in the workplace – raises and promotions – but the conditions are not always as clear. If employees do not know what the requirements are and they have no guarantees that they would reach that threshold why should they work harder? Vendor invoice transactions are a tedious task, but now, with the new reward system, employees can earn points and raise their status among other SAP teams. At the end of the month, a dollar amount is awarded to a charity of the winning team’s choice. This is all done through an upgraded version of their clerk software. It adds extrinsic value to the work, makes employees contribute to a cause they can relate to. We play games because they are fun. Play is not the opposite of work as entrepreneur Steve Keil tells us in his speech â€Å"A Manifesto for play†. It is also supported by Byron Reeves, a communications professor at Stanford University and author of the book Total Engagement (2009), who says that â€Å"The idea that work is work and play is play and never shall the two meet is melting quite a bit†. Games are fun which makes them engaging and we want our employees to be engaged in their work. One of the ways we can do that is by taking down factors that restrain and choke the individual. Once our goals are clearly defined and a scoring and reward system is set up as a frame, why do we need to keep restrictions in the workplace? Changes like making workday more flexible and eradicating fear by establishing an atmosphere of trust and cooperation instead of an authority. Like the millions of gamers around the world we want our employees to feel good when they come to work because that is going to translate into better quality of work, customer service and engagement. In a MMO there is always a comfortable social network system. No matter what they are doing, a level 1 player can contact level 60 players and ask questions. There is a strong sense of community and presence, because it is easy to form contacts. When there is a task that requires 5, 10 or 20 people, the task is divided into smaller tasks and everyone’s progress in visible from start to finish. That accessibility and transparency is not always available in businesses but they would go a long way to improving communication. In his book, Byron Reeves takes this one step further saying that some people will soon do their jobs inside a game. He draws a scenario where a woman would sit on her home computer and log on to a virtual world, in which she is represented by an avatar which she herself customized with badges and clothing, earned as rewards for completed tasks. Then she would take a look at her team’s progress by meeting their avatars. This is gamification in the modern business. When implementing the strategies from above, however there are a couple of things to be mindful of. First of all, managers have to make sure that the atmosphere of friendly competition does not go out of hand. With regard to the company’s mission statement, they have to recognize at what point employees stop working for the company and start working for themselves. The goals to reach thresholds have to be balanced. A task is engaging when it is challenging, yet accomplishable with the skill set that the employee possesses. Some business may not be well suited for gamification concepts. The data on employees will make promotions and layoffs more fair and transparent but it may also undermine the importance of a manager. Certainly the concept of gamification is still young, the interest that companies show towards implementing them points to a new trend. In her article, Silverman quotes the tech industry research firm saying that â€Å"by 1214, some 70% of large companies will use the techniques for at least one business process†. What was until recent years though to be a massive waste of time now changes the way we think about our jobs.

Free Essays - Analysis of Kate Chopins The Storm :: Chopin Storm Essays

The short story â€Å"The Storm† by Kate Chopin, deals with the subject of adultery. The story takes place in the early 1900’s. There are two main characters, Calixta (the wife) and Alcee (the former lover). Alcee must take refuge from a passing storm in Calixta’s house, while he is there the two end up making love while Calixta’s husband and son have to wait out the storm at the local store. By doing this Chopin implies the theme that is, adultery is natural and does not necessarily have negative consequences. Through out the story the constant changing of imagery plays a great role in the development of characters and their ability to demonstrate the theme. The subject of adultery was first introduced soon after Alcee asked Calixta if he may take refuge from the approaching storm within her house. That was also the first point when the author lets us know that Calixta â€Å"may† still have feelings for Alcee. This was shown clearly in the story when it says, â€Å" His voice and her own startled her as if from a trance†¦Ã¢â‚¬ Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Immediately after this the description of the setting changed from a outdoor relax feel to an indoor tense feel. This also lead to the feelings of both characters towards each other, which was shown when the room was described, â€Å" The door stood open, and the room with its white, monumental bed, its closed shutters, looked dim and mysterious.†Ã‚  Ã‚  Ã‚   Soon after this, Calixta who is then feeling the situation gets up to look outside the window, as not to keep looking at Alcee for she knows what may come of it. Alcee then also gets up to look out the window so that he may stand close to Calixta, which shows how Alcee wants to be with her. While Calixta is looking out the window she sees that it is raining hard and there is strong winds and lightning, which clearly signifies how mixed up Calixta’s feelings for Alcee are at that moment. After this Alcee grabs Calixta close to him as she staggers back, she then retreats and immediately asks where her son may be. This also shows that Calixta is having mixed feelings with the situation. Which is the reason she gets loose but does not tell Alcee to control himself but yet like nothing had happened wonders where her son may be, â€Å" Bonte! She cried, releasing herself from his arms encircling arms and retreating to the window†¦ If I only knew were Bibi was!†Ã‚  

Man Vs Nature Conflicts

Humanity's progress, particularly since the mid-19th century, has been largely the result of our ability to get and use what planet Earth has to offer. All told, the food we eat, the timber we cut, and the water we draw amounts to an astounding one-third to one-half of global ecosystem production. But humans are part of nature, and like every other species on the planet, we depend upon healthy ecosystems for our survival. Nature provides us essentials like clean water, food, medicines, even recreational retreats.Intact ecosystems also help regulate our weather and climate. But these systems are extremely fragile, and we're only now beginning to understand the myriad interactions and interdependencies that sustain them. And we know that once they are gone, there are no replacements. Changing our behavior and needs to preserve these Earth's ecosystems will be neither easy nor inexpensive. But if we are to feed, clothe, and care for ourselves into the future, taking drastic steps will b e essential. . Man- Nature interactionMan and nature interact dialectically in such a way that, as society develops, man tends to become less dependent on nature directly, while indirectly his dependence grows. This is understandable. While he is getting to know more and more about nature, and on this basis transforming it, man's power over nature progressively increases, but in the same process, man comes into more and more extensive and profound contact with nature, bringing into the sphere of his activity growing quantities of matter, energy and information.Why exactly do we humans have such an incredibly large influence on other species and the natural world? We are unique among animal species in that we survive and reproduce in a wide variety of environments through cultural adaptations. In contrast, other species are primarily able to survive and reproduce due to biological adaptations that result from eons of natural selection and biological evolution. The cultural adaptation s of humans have allowed them to colonize nearly every ecosystem type on Earth. In addition, cultural innovations have allowed the human population to grow exponentially for millennia.Such sustained population growth is unparalleled by any other species on the planet. The population of a typical species grows until it reaches the carrying capacity of its environment, then levels off or declines. In other words, it grows until it is fully utilizing the available resources, such as food and space. At this point mechanisms such as disease and starvation keep the population from continuing to grow. However, we humans have responded to resource scarcity with cultural practices and technologies that increase the availability of resources.We raise our food on farms and live in multi-story apartment buildings, increasing the carrying capacity of the environment for humans. This growth eventually requires yet more cultural adaptations to increase resources, and the alteration of the natural environment and the rate of cultural evolution is accelerated. Currently the global human population is large enough and the technologies that allow humans to manipulate the environment are potent enough that human-caused alterations to the biosphere are causing the extinction of innumerable wildlife species.If present trends continue, there will be an eventual crash in the human population that will bring great suffering and cause widespread environmental damage. This is the root cause of the modern environmental crisis. This deals with how we got into the present situation from the perspective of cultural interactions with wildlife and wild lands – coflicts conflict can be explained as the struggle between two class or group. In this essay we can see the differences that are a raised between man and nature.Since nature from the birth of earth the nature had a major role playing in every single aspect of living life on earth. as man develops slowly by improving day by day th e destruction of nature started. Man learned to develop the seed which helped both the environment by improving it's greenery and man by his efforts. Man vs nature conflict occurs when a particular character is opposed to natures forces. It is the conflict between nature itself, and mankind as we continue our relentless expansion, coupled with our overwhelming lack of compassion for any other form of life.A prime example of one such battle is that which currently rages in The Serengeti National Park. Currently, the Tanzanian government, despite earlier reports to the contrary, intends to pave the road which runs across 50 km of the park. The annual migrations in this region involve more than 1. 5 million animals, primarily wildebeests and zebras. These annual migrations are considered one of the great natural wonders of the world. The paving of this road would have dire consequences, both to the migrating herds and the local environment itself.The effects could be devastating to the natural balance throughout the area. The road would bring increased traffic, almost certainly resulting in massive loss of life to the herds. But as tragic as this would be, it is not the sole repercussion that would ensue A. overexploitation The exploitation of natural resources started to emerge in the 19th century as natural resource extraction developed. During the 20th century, energy consumption rapidly increased. Today, about 80% of the world’s energy consumption is sustained by the extraction of fossil fuels, which consists of oil, coal and gas.Another non-renewable resource that is exploited by humans are Subsoil minerals such as precious metals that are mainly used in the production of industrial commodities. Intensive agriculture is an example of a mode of production that hinders many aspects of the natural environment, for example the degradation of forests in a terrestrial ecosystem and water pollution in an aquatic ecosystem. As the world population rises and e conomic growth occurs, the depletion of natural resources influenced by the unsustainable extraction of raw materials becomes an increasing concern deforestation.Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. [1] Examples of deforestation include conversion of forestland to farms, ranches, or urban use. Urbanization (or urbanisation) refers to the increasing number of people that live in urban areas. It predominantly results in the physical growth of urban areas, be it horizontal or vertical. The United Nations projected that half of the world's population would live in urban areas at the end of 2008. [1] By 2050 it is predicted that 64.1% and 85. 9% of the developing and developed world respectively will be urbanized.Urbanization is closely linked to modernization, industrialization, and the sociological process of rationalization. Urbanization can describe a specific condition at a set t ime, i. e. the proportion of total population or area in cities or towns, or the term can describe the increase of this proportion over time. So the term urbanization can represent the level of urban development relative to overall population, or it can represent the rate at which the urban proportion is increasing.MARKET PRESSURES increase in commercialization, intensification and privatization of local economies, growing integration of national and global economies, economic reforms refer to market pressure. The list of such conflicts is extensive. One needs only turn on the news or read a local paper to find stories of such conflicts between man and nature. It is impossible to affect one link in the chain which comprises a given environment without incurring disastrous ramifications. Human beings are the ultimate embodiment of this destructive potential on the planet.Our encroachment upon†¦and in far too many instances outright destruction of†¦ various delicate habitats is well documented and comes in a variety of forms. These include: population growth impinging upon an animals natural habitat, destruction of the environment itself through pollution of the air, soil and water, disruption of migratory patterns, over fishing and hunting, deforestation and poaching. Mankind as a whole is the single greatest contributor to ecological imbalance on the planet. Why resources are under pressure?  · Increase in the sophistication of technology enabling natural resources to be extracted quickly and efficiently.E. g. , in the past, it could take long hours just to cut down one tree only using saws. Due to increased technology, rates of deforestation have greatly increased  · A rapid increase in population that is now decreasing. The current number of 7. 132 billion humans consume many natural resources.  · Cultures of consumerism. Materialistic views lead to the mining of gold and diamonds to produce jewelry, unnecessary commodities for human life or advancement.  · Excessive demand often leads to conflicts due to intense competition. Organizations such as Global Witness and the United Nations have documented the connection.Non-equitable distribution of resources.CONSEQUENCESThe Holocene extinction, sometimes called the Sixth Extinction, is a name proposed to describe the extinction event of species that has occurred during the present Holocene epoch (since around 10,000 BC). The Holocene extinction includes the disappearance of large mammals known as megafauna, starting between 9,000 and 13,000 years ago, the end of the last Ice Age. This may have been due to the extinction of the mammoth that had maintained grasslands that became birch forests without the mammoths.The new forest and the resulting forest fires may have induced climate change. [3] Such disappearances might be the result of the proliferation of modern humans which led to climate change. These extinctions, occurring near the Pleistocene–Holocene boundary, are sometimes referred to as the Quaternary extinction event. The Holocene extinction continues into the 21st century  · Erosion is the process by which soil and rock are removed from the Earth's surface by exogenetic processes such as wind or water flow, and then transported and deposited in other locations.Industrial agriculture, deforestation, roads, anthropogenic climate change and urban sprawl are amongst the most significant human activities in regard to their effect on stimulating erosion.CONCLUSIONConversely, to be honest, we are the species that holds the ability to have the greatest positive effect upon this worlds ecosystems. We have it within us to either save or destroy. The ability and the choice is ours. We as a species need to acquire an environmental conscience an awareness before our own shortsightedness and apathy doom us and our fellow denizens of this world to extinction.

Health Visitors’ Perceptions of their Role in Autism Spectrum Disorder

The discussion in the article mainly revolves and centers in two occurring forces particularly ASD and Health Visitors. The relationships being analyzed in these two topic areas are the progressively changing role of the health visitors towards the patient care of ASD cases. The center of study primarily is in England, United Kingdom, wherein the incident is clearly occurring and manifesting. Health visitors are the local health works that are in charge for the surveillance of these ASD patients and not mainly on public health. However, the argument arrives in the situation since this role is being interchanged gradually. The roles of health visitors over these ASD patients are important and boundaries should be set in order to avoid inappropriate practice. Autism Spectrum Disorder is a group disorder that manifest signs and symptoms related to the impairments of social communication and social imagination, with interest, behavior and activity constraints. Recently, there has been an increase in the prevalence rate of ASD specifically 1% of the child population or 116 per 10,000 children. The detection and surveillance of such conditions are part of the health visitor’s role. They are trained in order to detect such occurrence and help aid for those families that confronts the disorder dilemma. Health visitors act as part of the diagnostic team, and have a role of parent supporter. However, these roles are being disregarded because the common notion that health visitor’s job only revolves in referral system. Family-oriented type of role manifests in the health visitors and this serves as their guidelines in performing their tasks. However, a change in role towards public-oriented role is being issued. The developmental surveillance should function hence, these health visitors are requesting for trainings and developmental programs for their profession expansion. Current Treatments in Autism: Examining Scientific Evidence and Clinical Implications The condition of autism is under the umbrella of ASD or Autism Spectrum Disorder, and not entirely the disorder itself. Autism is characterized by the impairment in social interaction, imaginative play and language development. The etiological factor of this disorder, however, is still unclear. Many experts suggest that it is a neurological impairment enveloping the imbalance production in neurotransmitters, particularly serotonin. Other symptoms that are associated in this disorder are the presence of poor eye contact, ritualistic behavior, self-stimulating or abusive behaviors such as hand flapping, rocking or finger licking and lastly, absence of imaginative play. The diagnostic procedures of Autism condition lies in the behavioral manifestation of the patient. Such diagnosis can be depressive for families to receive since, Autism disorder do not have any direct cure as of now. However, there are treatment courses that are available for this type of disorder. Behavioral treatment is one of the treatment procedures that base their concepts on learning theory and behavioral analysis. The treatment procedure specifically targets the behavior of the individual since; this is where the manifestations arise. The intervention proposed aims to modify these behavioral patterns. Another treatment course is through educational and communication interventions. This intervention involves Project TEACCH (Treatment and Education of Autistic and Related Communication-Handicapped Children), PECS (Picture Exchange Communication System) and Greenspan's Developmental Approach. Each treatment programs focus on developmental and cognitive functioning of the child. There are also other forms of treatment, pharmacologic, social interaction modification, and health promotion interventions. Parent Education for Autism: Issues in Providing Services at a Distance Autism is a condition characterized by severe cognitive impairments leading to social interaction deficit, impairment in language and absence of imaginative play. These three symptoms are the primary indicators of Autism, and this disorder is under the umbrella of ASD or Autism Spectrum Disorder. The condition of Autism is known to have idiopathic conditions or unknown etiologies hence, direct treatments are not available. Fortunately, there are therapies that reduce the manifestations of behavioral signs and symptoms. Moreover, there are pharmacological therapies that aids in the management of the disorder. Due to the cognitive, social and behavioral deficits of these children, they are at risk of developing various threats. The article further elaborates the condition of Autism, mainly focusing on the three involved dimensions. Since autistic patients have impaired social interactions, their expression of their needs and concerns has to be sensed critically by the parents or the responsible supervisors. This kind of scenario implicates stress and other associated emotions to the family placing them under various family risk factors. In order to resolve such case, interventions have been developed in order to aid to the indirect problems under the disorder. The basis of these interventions is the behavioral principles associated in the disorder itself. Positive behavioral support, applied behavioral analysis and critical behavioral assessment are the concepts involved in the intervention procedures. Parents are the main access point for Autism behavioral interventions, hence; they are required to be aware of the possible treatment and intervention procedures that can be done with their patients. Parent education about the condition of Autism is stressed in order for the parents to be familiar with the behavioral conditions of their children, and be able to implement the appropriate intervention for such case.

Dr. Caligari as German Expressionism essays

Dr. Caligari as German Expressionism essays The German Expressionist cinema began in 1919 and was itself essentially an opposite of Impressionism. While Impressionism dealt more with giving an outward impression of an object, Expressionism sought to induce the emotional feel an object invokes on itself. Seemingly most often, Expressionist art is more about the artist than the subject. More importantly, however, is the fact that all definitions of "Expressionism" describe it as a theory of art that expresses feelings in an abstract way. The world may still be confusing, but some answers are found. Created by a people in effect displaced within their own country and society, German Expressionist films portray their own sense of displacement. It is not surprising then, that German Expressionism came to dominate horror and artistic cinema in the silent era. German Expressionism was more innovative and influential than any other film genre in the 1920s. It opened new doors to the possibilities of filmmaking, and the places an audience could be carried by them. German filmmakers began to create sets that personified the inner feelings of the characters set within them. The audience was able to visually identify the essential feelings of the action taking place because the scenes took elements of reality-based design and altered them to suit the mood. More over, German Expressionist film also advanced in two chief aspects of production beliefs. The first was the use of a studio for all aspects of shooting: absolute control was only possible if all sets and action took place within a studio. The other, more commonly seen in modern cinema, was the concept of giving an audience precisely what it wanted. Therefore, it was not surprising that while German Expressionist films were not always received well by the critics, they were most often quite successful at the box offices. In general, The Cabinet of Dr. Caligari is looked upon as the film which first brought Expressi...

A Business Plan to introduce Clean City Ltd

A Business Plan to introduce Clean City Ltd This document serves as a Business Plan to introduce Clean City Ltd, a registered Limited Company that was formed in January 2010. The sole purpose of Clean City’s business will be to solely engage/enforce the sorting of garbage, its collection, transportation and delivery/disposal to recycling plants and dumping sites, our main focus being recycling plants. What is Waste Management? Waste management is the collection, transportation, processing, recycling or disposal, and monitoring of waste materials, while Recycling is the process of re-using a given product (beyond its intended use), or producing a new product from a recyclable material. Nairobi’s population is approximately 4 million, 44% Kenyans fall below the poverty line, meaning approximately three quarters of Nairobi’s population falls under the urban poor category. In Nairobi, approximately 1,530 tonnes of garbage is generated daily and as illustrated in the Pie Chart below, approximately 1,130 tonnes of garbage rots uncollected close to its source, or is burnt in homesteads, dumped at illegal landfills or dumpsites or is collected by Non Governmental Organisations and Community based groups. Due to economic hardships and the high rate of unemployment, we have seen an increase of people migrating from rural to urban areas in search of better prospects to support their immediate families and/or dependants, and more often than not, most of these people eventually reside in low class areas such as the Kibera Slums or Peri-urban areas such as Gachie, Ongata Rongai, etcetera. Approximately half of the Kenyan population is based in Nairobi, and most of these migrants find themselves close to fragile areas such as rivers, valleys, steep slopes and adjacent to sewers or dumps. Nairobi City Council whose mandate is to provide and sustain a clean and healthy environment in Kenya has been unsuccessful due to its failure to formulate and adopt clear and comprehensive strategies that take in to account all aspects of waste management; its reluctance to involve stakeholders and to educate the general public on taking responsibility for their garbage disposal; and its manner in which it has disseminated information on the inherent dangers of inadequate attention given to waste management, or lack thereof. The Council’s Systems and Methods adopted to manage solid waste have failed to conform to the minimum requirements stipulated in the Environment Management and Co-ordination Act (EMCA) 1999, Part 11, Section 3(i). Generally it is poor governance. It is very sad indeed to witness adult pedestrians, motorists and passengers’ alike, ditching rubbish on footpaths, streets and roads without giving a second thought to the negative effects of their actions and having no regard for the beauty of Kenyan’s Capital, the Green City in the Sun. Majority of our young citizens, that is, our children, who are our leaders of tomorrow, innocently litter anywhere and e verywhere outside their homes and/or school premises, and in many instances this habit grows uncorrected because these young impressionable children mirror what many of us adults do resulting in a vicious cycle. Many of Nairobi streets and footpaths are littered with rubbish ranging from maize cobs, cigarette butts, fruit skins to plastic papers.
