Issues of Freedom and Power - Essay Example Economic freedom- Knights of labor Knights of labor, a major labor union during the 1860 hold a significant role in the evolution of economic rights in the United States. The formation of Knights of labor was the first efforts in the national labor organization because it was among the first labor unions to rally its members behind a goal. Nonetheless, the Knights of labor were a secret union characterized with less political pressure on its members. Uriah Stevens was the founder of the Knights of Labor, with many of his followers being Irish immigrant who were mainly Catholics. As a labor union, the Knights of labors enrolled members in various states to champion for improved rights of workers. Formed at a time when the United States repressed freedom of expression, the Knights of Labor worked in secrecy often recruiting its members using oaths and rituals. The main thrust of Knights of labor was to advocate for better economic reforms in their industries. At a time, when most of the immigrant received little pay and poor working conditions, the Knight of Labor became the ultimate vehicle to push for meaningful economic reforms. While the Knights of Labor avoided using industrial action, some of its members in states like Chicago were ready to strike. In 1886, about 80,000 people marched through Chicago supporting an eight-hour work shift. The long working hours were one of the main reasons that prompted the demonstration by members of Knight of Labor. This ignited confrontations between the Knights of Labor and the police who wanted to maintain law and order. In a social perspective, the Knight of Labor represented a growing awareness of rights among the workers. For instance, the call for an eight-hour work shift displayed a growing interest in social welfare among the workers.ii Most important, the meeting and demonstration among the workers guild indicated that rising level of social empowerment among the workers. Largely, the Knight of Labor has achieved many social gains because of its transformation from a secret labor to expressing its interest in various cities. Knight of Labor also championed for an end to child labor, a phenomenon that had characterized the American Labor environment. The political manifestation of 1960 would be incomplete without mention Knight of labor. Within the Knight Labor, there were some groups with interest to take control of the union. After leading a series of strikes, the government sentenced Albert Parson to death. This event made Lucy Parson seek ways of saving men that the government had convicted for deaths during strike. After visiting Europe in 1888, Lucy returned back American expressing new optimism in labor movements as she addressed workers and pressurized the state to create more projects in order to employ people. Political freedom (Progressivism- muckrakers and reform) The political freedom in the United States is a product of struggles that defined and helped create meaningful political reforms. With growing interest for political reforms, a group of Journalist joined hands to highlight on the wrongs of government through the literary works, which they published in magazines such as The Saturday Evening post McClure’

Pc Repair Documentation(Sample) Essay Example for Free

Pc Repair Documentation(Sample) Essay Ronels PC Repair lacks an accounting system, thus, profit or loss of the entity cannot be determined. The business is also often close because the owner usually attends home services. There is no business permit Objective of the Engagement To provide the best service available to the community at an affordable price and to have constant growth in sales by designing an accounting system best suited to the business so the operating performance is measured accurately. To help the owner in managing his business by hiring an apprentice To assist the owner in applying business license for his business operation Statement of Facts Personal Market Research by the owner indicates an attractive niche for the services of which PC Repair will take full advantage. The very nature of technological advancement, creates a constant need for businesses skilled in updating and advising customer on computer-related issues Our group has conducted an interview of the owner’s clientele; we’ve found out that 9 out of 10 customers are dissatisfied with other existing repair shop such as electronics repair shop, the one that’s nearest to the owner’s home office, considering the prices that they offer In addition, the owner stated that he will focus mainly on the small business market since the legality of its existence is still questionable since he hasnt applied for a business permit, and as these customer typically dont have a full-time IT person, but have full time IT needs Upon observation, there is no assistant employed to help him with the customers especially when he is not around. Moreover, customer are seeking skilled help with everything from installation of software and hardware components, to networking, to transferring files from an old computer to a new one, Findings and Conclusion Since there is no accounting system, determination of profit and loss are impossible because there is no recording of transaction especially for a proprietor who carries volume of transaction. It would be more convenient as a start up to use single entry method to record his transaction. In Single-entry bookkeeping transactions are recorded in registers with most transactions requiring only a single line to record the transaction. Marketing strategy will be implemented as well to promote the growth of the business and eventually hire an assistant to help the owner in managing the business and apply his business permit Recommendation: We recommend the use of Single-entry systems in the interest of simplicity. They are usually less expensive to maintain than double-entry systems because they do not require the services of a trained person. In addition, we will also recommend the owner to hire an assistant to help him; perhaps one of his apprentices before can be hired and to apply his business permit in the near future

Film Versus Theatre Presentations of William Shakespeares Much Ado Abo

Film Versus Theatre Presentations of William Shakespeare's Much Ado About Nothing Shakespeare's comedy Much Ado About Nothing is a witty play that is interpreted in many different ways for many different audiences. Branaugh's movie rendition, compared to the Shenandoah Shakespeare Company's play, have many separately emphasized points. If we look at elements such as use of space, costuming, and love relationships we find that Kenneth Branaugh emphasizes the separation of the military from the domestic which eventually heads down to the separation of men and women, while in the stage production, the director emphasizes the relationship and friendship between Claudio, Benedict, and Don Pedro. In Branaugh's movie version of Much Ado About Nothing there is much emphasis placed visually upon the military and the domestic atmosphere. From the beginning of Branaugh's interpretation the clear distinction between the two groups is visually portrayed. The movie begins with Emma Thompson, Beatrice, reading aloud to her friends and family in a relaxed laid back setting. The first domestic scenes lay out the tranquility of Leonato's home compared to the rough and public military scenes. The first military scene shows Don Pedro and his comrades riding up to Leonato's house. The scene is visually pleasing with the soldiers striding up to the house on horses with their arms raised in the air in slow motion. A strong sense of military valor is established through the soldier's actions, and the movie has already established a sense of military and domestic space, which the play did not capture. The Shenandoah Shakespeare Company's version of the play began very differently. There was no domestic or military atmosphere at all and the ... ...oin the domestic group, but Don Pedro and Don John are not as faded out. Don Pedro is present in the end, however, he is not a main part of the action. All of the characters were present most of the time either sitting on stage or standing which made the two groups seem not as separate as in Branaugh's movie. Branaugh and the company director both made many choices, which influenced their performances. I enjoyed the movie more the play because it was not only full of funny lines and puns, but the actors and the setting were amazing. They movie seemed to flow more for me and I enjoyed being able to see the characters in a serene setting without having to visualize it all. Shakespeare's play Much Ado About Nothing can be interpreted, acted, read, and visualized in different ways, but I thought that Kenneth Branaugh brought together an amazing cast and performance.

Antarctica Report †the environment and scientific research Essay

Introduction: The great icy continent of Antarctica is located at the south-most point on Earth and in the heart of the Antarctic Circle, referred to as the ice-cold desert. Antarctica covers the entire land and water region south of the latitude 600 S with no defined longitude, the continent spans around the entire Antarctic Circle. In reference to Australia, the eastern half of Antarctica ranges from a close 3,800km south of mainland Australia with Mawson Station located further west. Due to its location, early expeditions to Antarctica were usually carried out on boat with a stop at islands along the way i.e. Macquarie Island- now one of the four main Australian research bases in Australian Territory of the Antarctic Peninsula. Australia controls the largest part of Antarctica (43%) because of Sir Douglas Mawson’s expedition to Antarctica in 1929-31. During this expedition, Mawson and his team mapped majority of the Eastern coast, setting up camps along the way and eventually other Australian expeditions set up stations using these maps. Later when the Antarctic Treaty was established, this link with Antarctica and the fact that Australia was the first nation to map the eastern coast was considered, resulting in Australia’s claim to this area being granted, leaving them with majority of Antarctica. The governing of Antarctica is unique and very different from the rest of the world. It is governed by many nations that have all claimed parts of the continent for scientific research who all are guided and bound by â€Å"The Antarctic Treaty†. â€Å"The Antarctic Treaty† was designed and created by twelve original countries (there are now 38 countries) in 1961 to provide an agreement for the future care and use of Antarctica and to avoid territorial and other disputes. The Treaty encourages international co-operation in scientific research and in recognition of Antarctica being the last remaining â€Å"wilderness† on Earth, the ‘Madrid Protocol’ was established to help the conservation of the environment and peace on Antarctica. Elements of The Antarctic Treaty include: Antarctica shall be used for peaceful purposes only (Art.1), Freedom of scientific investigation and cooperation shall continue (Art.2), Scientific observations and results from Ant arctica shall be exchanged and made freely available (Art. III). Lying at the south-most point on Earth, Antarctica is truly a unique continent, renowned for a very harsh climate and an environment that has caused both, humans and animals, to adapt to the extreme conditions. Despite minimum infrastructure, Antarctica houses various forms of extensive scientific research conducted at its numerous bases. Climate: Mawson’s climate is typical of much of the coast of East Antarctica where the ice caps are present at sea level. The climate of Mawson Station can be described and categorized into four main areas: rainfall, temperatures, wind speeds and direction and mean daily averages. One of the main features of Mawson’s climate are the extremely cold daily maximums and minimums present there through most of the year. The mean maximum temperature ranges from its hottest at about 2.60C in January to the lowest daily maximum-15.60C in the peak of winter (July, August, September). The annual mean for the daily maximum is -8.40C, around the same as the mean in March and October. The mean daily minimums are not vey different to the daily maximums, a contrast compared to most parts of the world where the daily minimum and maximum have a greater difference. The mean daily minimum is at its highest in the month of January at -2.60C, dropping down considerably in March by almost 110C to -13.30C, marginally warmer than the annual minimum average of -14.3. Similar to the mean daily maximums, the mean minimums are at their lowest in winter, leaving a gap/difference of about 60C between the two (maximum and minimum). Although the mean temperatures around Mawson are mostly in the negatives, they are still a lot warmer and pleasant than those experienced in majority of Antarctica’s inland as the station lies near the coast and at a lower altitude of about 1,200m compared to the inland where altitudes rise up to almost 3,00m above sea level. Another characteristic of Mawson’s climate is the incredible winds experienced at Mawson and their high speeds. Winds around Mawson blow predominantly from the east and south, heading in a northwest direction. The mean annual wind speed is almost 40 km/h at 3pm, with some extreme speeds go past 120km/h during the year in peak winter (3pm). The maximum gust speeds exceed 140 knots frequently with the highest recorded wind gust ever in the area reaching an amazing 248.4km/h early in the morning. Wind speed are generally stronger during the winters, rising up to an average of 44km/h in August at 3pm compared to an average of 27-28km/h in December/January. Most precipitation falls as snow in Antarctica with no significant rainfall recorded near Mawson Station. As a result of Antarctica receiving less than 50mm of rainfall per year, the Antarctic region is classified as a desert-the coldest and driest desert in the world. Snowfall occurs regularly throughout the year-mainly during late summer when the snow is still able to fall without freezing. Although this snowfall is not very significant, it still has an impact on the climate around Mawson Station. The lowest temperatures at Mawson vary greatly as the seasons change. During the seasons of autumn and spring, the lowest ever recorded temperatures for each month (during these two seasons) have been very similar. The lowest temperatures of March, April and May all range within the late twenties to early thirties, almost identical to those of September, October and early November. Where as, the lowest ever temperatures in winter and summer are in great contrast, as the lowest during summer goes down to a less extreme -17.30C in February compared to freezing -360C in August. The reason for Antarctica’s very cold climate and its frequent change of size is the concept of the Earth’s revolution. The Earth is constantly rotating around an axis that runs through the north and South Pole at an angle of incidence (leaving the Earth always at a tilt of 23.50), completing one rotation every 24 hours. The Earths rotation is the reason that day and night are experienced, as when a part of the world is facing towards the Sun, it would be day, and when it rotates around to be away from the Sun, it becomes night. While the Earth is rotating on its axis (completing a rotation every 24 hours), it is in constant revolution around the Sun (completing a revolution every 365 days). As the Earth is always tilted the same way, the stage at which the Earth is at during its revolution determines the concentration and strength of the rays hitting the particular area. For example, if it is December 21 in the southern hemisphere the angle of incidence will have this part of the Earth closer to the Sun/tilted towards it causing the Sun’s ray to be concentrated at a smaller area and thus being stronger and creating more heat. This is because; during summer the Sun is directly above the Earth due to the tilt. As the equator is in no hemisphere, the angle of the rays is the same throughout the year, creating the same season for 365 days. Where as, the poles, which are located at top of the northern hemisphere and bottom of the southern hemisphere, have two completely different seasons. During summer they rotate around the axis but are always facing towards the Sun, thus having sunlight for almost 24 hours per day. However, during winter, the poles- in this case the south pole- is tilted away from the Sun and when rotating on the tilted axis, it remains away from Sun for most of the time, thus having no sunlight. This process/revolution continues for the whole year, in which the South Pole has experienced both summer and winter. Because of this reason and that it is located around the South Pole, Antarctica experiences these extreme amounts of daylight and darkness. As a result of these extreme seasons, a huge amount of sea ice is formed during winter, as the temperature gets extremely cold, quickly melting as summer approaches and the temperature rises above freezing point. If Antarctica were located near the equator, this effect would not occur as firstly, the temperatures would not be as low because the suns ray’s are stronger there because of the angle of incidence, but also the change in seasons would not be as extreme with the hours of daylight barely varying throughout the year. Mawson Station: Location: Mawson is a particularly favourable location for a station, with excellent access to the hinterland/open inland areas and surrounding coastal waters. It is also located near a harbour sheltered from the main body of the ocean and with a large depth and mouth not too narrow, during the ice-free period usually experienced in February, a ship may anchor within 100 metres of the station. Barges carrying the cargo would take only a few minutes to travel from the ship to station as it is located right on the shore. There is also a â€Å"magnetic quiet area† for research and tests requiring very little magnetic interference. The Station: The base at Mawson has a very simplistic layout. It consists of many buildings in a spread out area (as shown in the image on the right) each for different purposes with the science related buildings located closer to the shore. Everyone lives in the main accommodation building (the Red Shed; located the furthest from the shore), in modern air-conditioned single-room bedrooms. The Red Shed also houses the surgery, lounge, kitchen, and dining room. The Red Shed at Mawson base has indoor climbing, a home theatre, photographic dark room, a library and several common sitting areas for passing time during the winters. As it is a multi-recreation and living building, neither scientists nor other workers conduct their research there but expeditioners use it for day-to-day work. The green store is another one of the buildings that dominate the skyline at Mawson. It is located in front of (closer to the harbour) the Red Shed and is where all the dry food and most frozen food are stored. The clothing store, field store and equipment spares are also located here. Inside is rock climbing wall and open space for games like volleyball. Similar to the Red Shed, the green store is used for day-to-day work rather than scientific research. The operation building (the yellow building near the green store) houses the Station Leader’s office, communications, the post office and the Bureau of Meteorology. It is the home for the work of the telecommunication technicians, station leaders and many electricians. The Main Power House (the blue building near the shore) is where all the electricity for the station is generated and is where many more of the electricians, technicians and mechanics work. Waste heat from the generators is piped around the station and used to heat the buildings. The trades’ workshop (known as Red Dwarf), located near the main power building, houses all the offices and work area for the trades such as the Diesel mechanics, plumbers and electricians. The waste management building is responsible for processing all sewerage and non-toxic liquid waste. It is located a bit away from the main part of the station with very few workers. The cosmic ray observatory (located near the airstrip and shore) contains telescopes that detect and measure cosmic rays coming from outside our solar system. It has a shaft going down in the rock to a vault to a second set of telescopes and also some seismic detection equipment. It is home for scientists working in the field of seismology, cosmic ray physics, meteorology and atmospheric physics. The Anaresat dome (next to the Red Shed) is the home to technicians in the field of telecommunications and scientists in the field of Cosmic Ray physics. The general science building (where the biologists and geophysicists work) is located behind the green store. The Aeronomy (home to atmospheric space physics and climate change studies) is where majority of the atmospheric physicists work and the white building is located at the far corner, away from the shore. The carpenter’s workshop is where the carpenters do majority of their work. The building is located near the middle of the station, standing out with its brightly coloured doors. The Magnetic Variometer hut- a special building that houses sensors that measure and record the changes in the Earth’s magnetic field- and the magnetic absolutes hut are located next to each other behind the waste disposal hut, write on top of a magnetically quiet area. At Mawson Station, there is also a emergency vehicle shelter where all the fire fighting equipment is stored, a high frequency radio-transmitter hut, one aircraft hanger, three helipads (used infrequently), numerous inflatable rubber boat sheds, the wharf (where cargo is loaded and unloaded), a Sun recorder building and two fuel farms all spread out around the station. Most of these buildings are located in a cluster together with few in a different location due to restriction and needs i.e. magnetically quiet areas. The scientific programs undertaken in and around Mawson include: * Middle and upper atmosphere physics. * Cosmic ray physics and meteorology. * Geomagnetism and seismology. * Biology and medicinal studies. * Automated upper atmospheric sciences. * Climate change studies. Although one of the harshest environments on the planet, Antarctica is also one of the most vulnerable and is rapidly being effected as a result of human behavior. There have been many effects on the environment and wildlife in Antarctica caused by humans- mainly tourists that come and go- and their activities. Humans travelling to and from Antarctica (tourists and scientists) are the cause of many impacts on the environment as their trips involve the ships, accommodation, vehicles and other amenities which all can have an impact on the environment. One of the major impacts humans are having on Antarctica’s wildlife, is that the usual feeding and huddling grounds for penguins and other animals are being disturbed and in some cases, destroyed, taking away the habitat and vegetation needed for them to survive. This is a result of many tourists and scientists using areas- that are important to wildlife- for their own needs and desires (i.e. camps, research facilities), leaving the wildlife to find new homes and adapt to conditions sometimes not suitable for their needs (i.e. not close enough to the water, not large enough or not the right climate). The mode of transport taken by most visitors, boats, is harming the marine life and destroying parts of their environment. Various shapes and sizes of boats are cutting through the Southern Ocean and arriving in harbours where the marine life and depth is quite shallow. In some occasions, fuel tanks are being scraped, creating a minor leak in them that, over a period of time anchored at the harbour, releases tonnes of fuel and other toxic chemicals, scarring the marine life. As a result of this and to prevent further release of toxic chemicals, The Australian government and the ADD have banned large ships or boats with old systems and engines from entering Antarctic waters, reducing the possibility of harm to marine life. As for the problem of destruction to wildlife habitats, the ADD has developed laws that prohibit the use of wildlife-important areas for human use. As a result of this, scientists and visitors are banned from using areas with high importance to animal activity (i.e. breeding grounds and huddling areas) and instead forcing them to work in already human-developed areas like stations. Another impact that humans are having on Antarctica’s environment is the increasing amount of environmental pollution being released in forms of excess waste being dispersed into the oceans and environment in the form of litter. Due to an increasing number of people in Antarctica every year, tonnes of extra waste are being produced and dumped everywhere, releasing toxic chemicals which can become concentrated in the bodies of local wildlife, such as seals, penguins and whales, harming them in the long term. The issue of excess waste polluting the environment is also a result of original waste management strategies not being adequate or designed for a situation like this where the amount of humans present in Antarctica is much more than forecasted. Until relatively recently, waste disposal management in Antarctica was similar to elsewhere in the world with open tips, land fills and the burning or discharging of most sewage into the sea, as well as the practice of ‘sea-icing’ – dumping rubbish onto the sea ice during winter to float away and sink during the summer, with the areas around stations being contaminated from oil and chemical spills. Now, after new laws protecting the environment of Antarctica, waste is being split into many categories, each with a different strategy to stop the release of it into the environment. Hazardous materials such as polystyrene beads and radioactive materials are prohibited from entry into Antarctica; most other wastes are to be incinerated in a two-stage high incinerator with the resultant ash returned to Australia, metals, plastics, paper, cardboard and glass are separated and returned to Australia for recycling and the installation biological sewage treatment plants are all strategies that the Government of Australia are using to prevent pollution- as a result of excess waste- into the Antarctic environment. Adaptations to the Antarctic Environment: Human Adaptation: Comparisons Between Mawson’s Expedition and Today Mawson Today Transport * Wooden sleds pulled by dogs- not very stable and efficient. * Large wooden boats and ships with sail and masks. * Feet- walking around and pulling sleds with back. * Wooden, mechanic carts for transporting things around bases. * Used the ship Aurora Australis when it was fist made in 1950s. * Small planes that can land on large strips of ice. * Helicopters for shorter distances or rescues. * Small cruise ships with navigation, etc. * Off road vehicles for driving around the station. * Emergency vehicle shelter for vehicles used in emergencies. * The inflatable rubber boats for summer months when ice has blown out. Equipment * Wooden shovels, a compass and mostly non-automated equipment. * Signals to communicate and fire for heat-no phones or electrical heat. * Basic survival equipment- a limited amount taken on expeditions- food, necessaries, etc. * Basic tents prone to being destroyed in strong winds-not completely water tight. * Some metallic, some wooden tools to dig, cut and carry items in. * Telecommunication and navigation ways like phones, GPS’s and full-proof maps. * Waterproof tents with firmness to withstand strong winds. * Metal tools to dig, cut, gather water and cook meals. Good quality equipment. * Normal da to day equipment like boxes to keep samples in. Clothing * Several layers of basic warm clothing-no proper insulation-weighed more than modern clothing. * Gloves, fabric headgear (beanie like0 covering most of face with no proper insulation for the nose. * Insulated clothing with minimum weight. * Brightly coloured clothing to stand out and be easily spotted. * Clothing that can get wet and dries quicker than most. * Gloves, beanies, and nose protection with maximum insulation. Humans have adapted to the Antarctic climate with the use of new technology, more user-friendly equipment like automatic vehicles rather than human –pulled sleds and clothing that not only protects expeditioners from the cold with better results than clothing used in Mawson’s expedition, but at the same time is also comfortable to wear, allowing activities to be completed with ease. Todays transport in Antarctica- off-vehicles, portable rubber boats and small aircrafts- are all much more efficient than those used in Mawson’s expedition- human or dog pulled sleds and wooden carts. They require less human strength and energy that can instead be used in conserving body heat, are a lot less time consuming allowing more work to be completed or a greater distance covered in an expedition and most of all, the new forms of transport are much more reliable with a less risk of breaking down or failing in the middle of an expedition. Another adaption humans have made to help battle the Antarctic climate is their improved clothing that has better insulation, conserving more heat. This clothing has made humans feel as if they are feeling the same temperature as in other cold places around the world with very little extra weight on themselves. They have also been able to carry tools around on expeditions that can dig, cut and build with greater ease than those of Mawson’s expedition. This adaption has allowed humans to not be prevented and stopped by physical barriers on Antarctica and instead overcome them, using stronger tools like those used around the world. Animal Adaptation: Every environment is subject to changes that vary from season to season and from year to year. Even in Antarctica where it is always cold the variations can be quite marked. For example, the number and intensity of storms and blizzards can vary from year to year as can the time at which the sea-ice forms in autumn or breaks out in summer. These environmental changes are likely to have an influence on the animals that live there. Nature has provided the emperor penguin with a need to adapt to the extreme conditions of Antarctica. Standing 1.2m tall, over time the largest penguin has developed many physical and behavioral adaptations that leave it as a truly amazing bird, which not only easily survive the Antarctic winters, but also are also capable of doing almost anything during the time. Emperor Penguins have excellent insulation against the cold in the form of several layers of scale-like feathers that take very strong winds (over 60 knots) to get them ruffled. They have a very small bill and flippers, which conserve heat and are not as exposed to the temperatures due to their size. Their nasal chambers also recover much of the heat that is normally lost during exhalation. They also possess strong claws in their feet for gripping the ice and slippery surfaces, allowing them to waddle instead of sliding around on their bellies all the time. Another special physical adaptation of the emperor penguin is the ability to ‘recycle’ its own body heat. The emperor’s arteries and veins lie close together so that blood is pre-cooled on the way to the bird’s feet, wings and bill and warmed on the way back to the heart. Emperor penguins have large reserves of energy-giving body fat to use during low-level activities during winter. The emperor penguin also possesses many behavioral advantages to survive in the climate of Antarctica. They are very social creatures, and one of their survival mechanisms is an urge to huddle together to keep warm. To keep warm, the males close ranks to share their warmth. Even though Emperors are large birds and when carrying their incubation fat, they are about as large around the chest as a human, they still huddle on very cold days, with as many as ten packed into every square metre, cutting heat loss by as much as 50%. This huddling instinct means that they do not defend any territory (the emperor penguin is the only species of penguin that is not territorial) and instead radiate heat and keep warm together. Another behavioral technique used by the emperor penguin to survive the conditions in Antarctica is their ability to mate and reproduce during winter rather than in summer and take care of their eggs. Like most penguins, emperor parents closely share parental duties. What is unique about emperors however, is the co-operation between males while carrying out their parenting duties. Once the egg has been laid during winter, the male emperor puts the egg under his brood flap to keep it warm at about 380C so that the egg can eventually hatch instead of dying inside. During this period of a few months, the male does not eat anything and instead closes together with the others to stay warm himself and to keep the egg warm while the mother goes off to find food. When she comes back after winter is almost done, the chick, which would have hatched around the time, is fed and looked after until December at which stage, they are almost the same size as their parents. Because of this cycle formed by the emperor penguins and the ability to breed during winter, the young are hatched and brought up during the early summer instead of peak winter, giving them a higher chance of survival. Conclusion: From the harsh and extreme climate to the rocky and wildlife-populated shores, the continent of Antarctica is unique in almost every way. Larger than two continents combined, covering the South Pole and the driest of the deserts every seen, along with the majestic ice sculptures found nowhere else on the planet, Antarctica draws hundreds of tourists every year to experience these wonders from the welcoming surroundings of world renowned stations established by expedition leaders like Sir Douglas Mawson. No doubt, both humans and animals have had to adapt to the frantically changing climate, but now that they have, they too are enjoying the beauty of Antarctica.

Mawson station- an Australian scientific research base named after Sir Douglas Mawson- is located on the eastern side of Antarctica currently claimed by Australia at 670S 620E and south of the Antarctic Circle. Mawson is situated along an isolated outcrop of rock on the coast in Mac.Robertson Land and the south eastern shore of Horseshoe Harbour. Although usually considered closer to Hobart than any other Australian city, Mawson Station is actually situated about 5,475km from Hobart, further than the 5223km southwest of Perth. Relative to Australia’s main cities, Mawson Station lies far to the west of them, falling between South Africa’s Cape Town and Perth in the Southern Ocean. Australia owns and maintains three permanent scientific research bases all located within Australia’s main Antarctic region and one on Macquarie Island in the sub-Antarctic. The three stations are evenly distributed along the coast of Antarctica with Mawson being the most westerly of the three continental stations and the first one built and established. Davis is the most southerly of the stations and is situated SSW of Perth, on the Ingrid Christensen Coast of Princess Elizabeth Land and between the other two. Casey is located in the Windmill Islands, just outside the Antarctic Circle and the only one of three located outside the Antarctic Circle. 2. Mawson’s climate is typical of much of the coast of East Antarctica where the ice caps are present at sea level. The main features of Mawson’s climate are the extremely cold temperatures present there through most of the year. The mean maximum temperature ranges from about 2.50C in January to -15.50C in the peak of winter (July, August, September). Although temperatures around Mawson are mostly in the negatives, they are still a lot warmer and pleasant than those experienced in majority of Antarctica’s inland as the station lies near the coast and at a lower altitude. Winds around Mawson are predominantly from the east and south with the mean annual speed being almost 40 km/h while extreme speeds go past 120km/h in peak winter and maximum gust speeds exceed 140 knots frequently. As it lies south of the Antarctic Circle, the Sun does not rise at Mawson for approximately six weeks from the first week in June and does not set for the same period from early December. During those six weeks in June and July, the day consists of a few hours of twilight. 3. The Aurora Australis is Australia’s Antarctic flagship and was named after the aurora emitted around Antarctica. Designed as a multi-purpose research and resupply ship, the Aurora was built for the Australia Antarctic Program by P&O Polar and launched in September 1989. The ship is 94.9 metres long and 3911 tonnes in weight. It has a cruising speed of 13 knots, and accommodates 116 passengers plus crew. It is capable of breaking ice up to 1.23 metres thick. The Aurora regularly sails across the Southern Ocean where storms can generate 10 metre high seas and winds of 120–150 km/h. The Aurora Australis, designed specifically for trips to and from Antarctica, has many features for this instance. Six of these features are: * Installed in the ship are ways for satellite communications (not present on mainland Antarctica), allowing people on the ship to phone anywhere in the world at any time or stay in touch by email. * The ship’s kitchen can go through 4500 eggs, 1000 kg of potatoes and 280 litres of ice cream. The ship can produce up to 45,000 litres of fresh water per day for use on board for both drinking and other uses. As the trip to Antarctica and back can easily take up to six weeks, a large kitchen and food supply are extremely necessary. * The ship’s colour, bright orange, is painted all around it so that it can stand out in the ocean and making it easier to spot for rescue teams. * Three helicopters can be housed in the hangar and operate from the dedicated helicopter deck at the rear of the ship. They can go to and from the ship ahead to Antarctica or rush back to Australia in an emergency via the ship to refuel. * The ship is well equipped for marine science research with a commercial sized trawl deck, and a commercial hydro acoustic system for the assessment of Southern Ocean organisms such as krill. It also has a general-purpose lab for processing net samples, a hydrographic lab, fish freezer, meteorological lab, five multi-purpose laboratories, a photographic dark room and a scientific workroom. * The Aurora Australis is painted a very bright orange, thus allowing it to be easily seen and spotted in ice-spread waters. 4. Mawson base was first established on 13 February 1954, when an expedition led by Dr Phillip Law landed on the shore of Horseshoe Harbour (located on the coast of Mac Robertson Land), naming the new station in honour of Australia’s greatest polar explorer, Sir Douglas Mawson. Law had chosen this place to establish the station after viewing photographs of Mac Robertson Land from the expeditions of 1929-1931 led by Sir Douglas Mawson and 1946-47 by an aircraft from an American expedition. He chose the location because of its key locality near the coast, the large natural harbour (Horseshoe Harbour), a major hotspot for wildlife to conduct scientific research on and the permanently exposed rock present there for building, requiring very little to be shipped over. During the first year, living quarters, a works hut, the engine shed, two store huts and a carpenter’s shop were built and by 1966, the number of buildings had increase to fifty including the construction of the first aircraft hanger in Antarctica. Mawson’s location lies on the coast with Horseshoe Harbour spread around it. At the southern end of the station, (Horseshoe Harbour), ice sheets cover the waters surface near the shore, leading out into the Southern Ocean. The Mawson region is one of the richest areas for seabirds in the Australian Antarctic Territory, and supports living colonies of emperor and Adelie penguins, petrels and seals. The base at Mawson has very comfortable living conditions. It consists of many buildings in an area (as shown in the image on the right) each for different purposes. Everyone lives in the main accommodation building (the Red Shed), in modern air-conditioned single-room bedrooms. The Red Shed also houses the surgery, lounge, kitchen, and dining room. The Red Shed at Mawson base has indoor climbing, a home theatre, photographic dark room, a library and several common sitting areas for passing time during the winters. The green store is one of the buildings that dominate the skyline at Mawson. It is also where all the dry food and most frozen food are stored. The clothing store, field store and equipment spares are also located here. Inside is another rock climbing wall and open space for games like volleyball. The operation building houses the Station Leader’s office, communications, the post office and the Bureau of Meteorology. The Main Power House is where all the electricity for the station is generated. Waste heat from the generators is piped around the station and used to heat the buildings. The trades’ workshop (known as Red Dwarf) houses all the offices and work area for the trades such as the Diesel mechanics, plumbers and electricians. At Mawson Station, there is also a waste management building, emergency vehicle shelter where all the fire fighting equipment is stored, a high frequency radio-transmitter hut, one aircraft hanger, three helipads (used infrequently), a cosmic ray observatory, The Anaresat dome (a large satellite dish), numerous inflatable rubber boats, the general science building (where the biologists and geophysicists work), the Aeronomy (home to atmospheric space physics), the carpenter’s workshop, Magnetic Variometer hut- a special building that houses sensors that measure and record the changes in the earths magnetic field, magnetic absolutes hut, the wharf (where cargo is loaded and unloaded), the Sun recorder building and two fuel farms. Facilities At Mawson Station Transport Scientific Other Amenities * The emergency vehicle shelter with fire-fighting equipment and other vehicles. * The three helipads and one aircraft hanger and airstrip (currently out of use). * The post office and the high frequency radio transmitter hut for communication. * The inflatable rubber boats for summer months when ice has blown out. * The wharf (the cargo dock). * The cosmic ray observatory and the Bureau Of Meteorology. * The Anaresat dome with the large satellite dish. * The photographic dark room and the library inside the Red Shed. * The general science building where majority of the science is conducted. * The Aeronomy- atmospheric space physics. * The Magnetic Variometer Hut. * The magnetic absolutes hut. * A Sun recorder building. * The Red shed’s living quarters, surgery, lounge, kitchen, dining, theatre and recreation rooms. * The facilities in the Green Store: frozen food storage, clothes store, equipment spares, field store and rock climbing wall. * The waste management building, offices and the main powerhouse. * The gym building (formerly a general room). 5. The four main priority programs undertaken by Australian research scientists in Antarctica are: * Climate processes and change. * Terrestrial and Near-shore Ecosystems: Environmental Change and Conservation. * Southern Ocean Ecosystems: Environmental Change and Conservation. * Frontier Science Climate processes and change: Climate Processes and Change investigates the role of Antarctica and the Southern Ocean in the global climate system. Its main focus and importance is to address uncertainties identified in â€Å"The Fourth Assessment (2007)† report, which highlights the lack of climate data around the Southern Ocean and Antarctica. It also investigates the role of the region in slowing climate change and the future behavior of the ice. Terrestrial and Near-shore Ecosystems: This program investigates the effects of environmental change on Antarctic and Sub-Antarctic terrestrial and coastal ecosystems. This program provides the scientific basis to guide and develop enhanced environmental protection for these ecosystems. Southern Ocean Ecosystems: the Southern Ocean is facing many threats to its marine life and ecosystems as a result of physical and biological changes that are being caused because of fishing, climate change and acidification. Scientific research under this theme is helping scientists understand the impact of global change on Southern Ocean ecosystems, the effective conservation of Antarctic and Southern Ocean wildlife and the sustainable, ecosystem-based management of Southern Ocean fisheries. Frontier Science: The focus of Frontier Science is to encourage and support research that falls outside the priorities of the other research departments along with focusing in the environmental science in the other categories. It is basically about learning about sciences beside climate change and the causes and effects of them. 6. If you were travelling to a penguin colony 90 kilometres away from Mawson Station, you would most likely travel by a small plane or helicopter capable of landing without requiring a constructed airstrip or helipad. These to options would be far better than by land as conditions along the way could potentially halt your journey-leaving you stranded without support or rescue, it would take a lot longer and a lot more supplies and clothing would be required. Adequate clothing would be required to battle the cold temperatures especially during winter. You would carry and wear a thermal, a suit that constrains heat, thick gloves, headwear that covers majority of your face as well, long insulated pants, thick jackets and other items of clothing usually warn also in Northern Russia and Canada. 7. The area of Antarctica is almost double the size in September than in March as a result of sea ice freezing during the winter (September) and melting during the summer (March). Over a 12-month period, the sea ice begins to melt and the size of Antarctica begins to decrease towards the end of September. It continues to do so until March, when it is almost half the size. Once again, when winter begins around the beginning of April, the sea ice begins to gradually freeze; increasing the area of Antarctica every month until September before the cycle begins again. Scientists use a variety of technology to research these changes. They use drones and satellites to examine the area and measure the increase of size. The satellites map out the area and give an aerial view for scientists to examine and interpret. They examine the oceans, atmosphere and climate patterns to describe and prove how the change occurs. An ice core is a core sample that is typically removed from an ice sheets, most commonly from the polar ice caps or high mountain glaciers. As the ice forms from the incremental build up of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years. The properties of the ice and the recrystallized inclusions within the ice can then be used to reconstruct a climatic record based around the age range of the core, normally through analyzing their elements. This enables the reconstruction of local temperature records and the history of atmospheric composition as they contain information about the past climate. 8. Over time the emperor has developed many physical and behavioral adaptations that leave it as a truly amazing bird, which not only can survive the Antarctic winters, but also are capable of doing almost anything during the time. Unlike other animals that have inhabited Antarctica, emperor penguins spend time on both land and water throughout the year, being able to do what they like without the fear of fearful predators and possibly not surviving through the winter. Emperor Penguins have excellent insulation against the cold in the form of several layers of scale-like feathers that take very strong winds (over 60 knots) to get them ruffled. They have a very small bill and flippers, which conserve heat and are not as exposed to the temperatures due to their size. Their nasal chambers also recover much of the heat that is normally lost during exhalation. They also possess strong claws in their feet for gripping the ice and slippery surfaces, allowing them to waddle instead of sliding around on their bellies all the time. Another special physical adaptation of the emperor penguin is the ability to ‘recycle’ its own body heat. The emperor’s arteries and veins lie close together so that blood is pre-cooled on the way to the bird’s feet, wings and bill and warmed on the way back to the heart. Emperor penguins have large reserves of energy-giving body fat to use during low-level activities during winter. The emperor penguin also possesses many behavioral advantages to survive in the climate of Antarctica. They are very social creatures, and one of their survival mechanisms is an urge to huddle together to keep warm. To keep warm, the males close ranks to share their warmth. Even though Emperors are large birds and when carrying their incubation fat, they are about as large around the chest as a human, they still huddle on very cold days, with as many as ten packed into every square metre, cutting heat loss by as much as 50%. This huddling instinct means that they do not defend any territory (the emperor penguin is the only species of penguin that is not territorial) and instead radiate heat and keep warm together. Another behavioral technique used by the emperor penguin to survive the conditions in Antarctica is their ability to mate and reproduce during winter rather than in summer and take care of their eggs. Like most penguins, emperor parents closely share parental duties. What is unique about emperors however, is the co-operation between males while carrying out their parenting duties. Once the egg has been laid during winter, the male emperor puts the egg under his brood flap to keep it warm at about 380C so that the egg can eventually hatch instead of dying inside. During this period of a few months, the male does not eat anything and instead closes together with the others to stay warm himself and to keep the egg warm while the mother goes off to find food. When she comes back after winter is almost done, the chick, which would have hatched around the time, is fed and looked after until December at which stage, they are almost the same size as their parents. Because of this cycle formed by the emperor penguins and the ability to breed during winter, the young are hatched and brought up during the early summer instead of peak winter, giving them a higher chance of survival. Scientists are continuously researching and discovering new behavioral and physical facts about the emperor penguin. They capture the penguins for a while to examine them, using state of the art technology undertaken by biologists both on Antarctica and back in Australia. Some of the research includes: learning about the emperor’s breeding habits, physical body, behavior habits and they are adapting to the changing climate. 9. Tourist travel to Antarctica for a wide range of reasons including an opportunity to experience and view the unique environment with incredible icebergs, auroras, ice arches and wildlife only seen and present there. Tourists usually make the boat trip to Antarctica during the summer between October and February as the climate is at its best, the pack ice is at its lowest, the Sun is high in the sky for most of the day and wildlife is most active at the time, wondering out into the open. A typical journey taken by a tourist to Antarctica usually begins in either: Ushuaia (Argentina), Hobart (Australia), Cape Town (South Africa) or Christchurch (New Zealand) with most choosing the first two. A large boat or small ship is taken from one of these locations, before a long few weeks spent on the waters in more than adequate living conditions. During the journey, tourists can take part in many activities normally present on basic ocean cruises. These include activities like swimming, movies, dining, whale watching, witnessing sights found nowhere else on Earth and other activities to pass time. Once arriving at a station in Antarctica, tourists spend their time on the continent in and around the station, undertaking numerous activities ranging from casual indoor activities like rock climbing, viewing scientific programs and spending time in the library to outdoor activities like watching the penguins, taking a sea kayak to get a close up on sea birds and whales, trekking past and up majestic mountains, scuba diving, walking on the ice and exploring historic huts left behind by various expeditions. There are many impacts on the environment and wildlife in Antarctica caused mainly by the tourists that come and go. The tourism industry to Antarctica involves much more than just the tourists as it involves the ships, accommodation, vehicles and other amenities required for the tourists. Because of this, the wildlife is having a major impact with usual feeding and huddling grounds for penguins being disturbed ad in some cases destroyed along with other places for other species like the rocks being used for construction, taking away the habitat of the seals. Tourists also have an impact on the environment like they do all around the world with specific places being developed especially for them. Parts of Mawson Station has been developed and built recently just for tourists, destroying parts of the natural environment as many of the materials like rocks come from Antarctica instead of being shipped over. The transport in which tourists arrive, boats, also have effect the waters as oil spills- regular due to the ice- pollute the waters harming the whales and other marine life. As a result of this, large ships have been prohibited from the waters around Antarctica as they not only pollute the water, but also disturb and crack the ice. Waste management is another problem occurring at Mawson Station with tonnes of waste accumulating on the continent, creating a major headache for workers to clean up before it’s the toxic chemicals start having an impact on the environment.

Novel about sin essays

Novel about sin essays The puritans were fascinated with the effect of sin upon the human heart. Nathaniel Hawthorne, who is a puritan writer, considers the effect of sin upon the human heart fascinating as well. The Scarlet Letter is not a novel about adultery but a study of the effects of sin on the hearts and minds of Hester, Dimmesdale, and Chillingworth. Sin is a double-edged sword in the life of Hester Prynne. The effects of sin on her character are not only defining and powerful, but they are also ambivalent. The most obvious effect of son on her is that it isolates her from her community. We see this from the very beginning of the story, when we first encounter her standing alone on the platform. This is not the last time we see her standing alone this situation recurs throughout the story. The fact that she is labeled as an adulteress is a large reason as to why she is separated from society. She reacts to this with a blush of shame and a look of defiance at the same time. Her reaction to the sin and societies opinion of that sin continues throughout the book, as well as her growing feeling of shame and repentance. After the scaffold scene, Hester seemingly conforms to the puritanical code of society. She does works of penance and good will that appear as if she is trying to atone for her sins and faults. This seemi ngly obvious admission of sin is nothing less than hypocritical. She acknowledged any truth in societies accusations of her love as a vile crime. She admits this when she says to Dimmesdale what we did had a consecration of its own. We felt it so! We said so to each other! (Hawthorne 186). Hester continues her repentance for her sin, but in her mind still believes that what they did was not wrong. She believes this so fervently that she actually convinces Dimmesdale to leave Boston and goto Europe with her and Pearl. She and Pearl are the only ones who actually make it to Europe. ...

Free Essays on Thomas Edison

Edison, Thomas Alva, 1847–1931, American inventor, b. Milan, Ohio. A genius in the practical application of scientific principles, Edison was one of the greatest and most productive inventors of his time, but his formal schooling was limited to three months in Port Huron, Mich., in 1854. For several years he was a newsboy on the Grand Trunk RR, and it was during this period that he began to suffer from deafness, which was to increase throughout his life. He later worked as a telegraph operator in various cities. Edison's first inventions were the transmitter and receiver for the automatic telegraph, the quadruplex system of transmitting four simultaneous messages, and an improved stock-ticker system. In 1877 he invented the carbon telephone transmitter (see microphone) for the Western Union Telegraph Company. His phonograph (patented 1878) was notable as the first successful instrument of its kind. In 1879, Edison created the first commercially practical incandescent lamp (with a carbon filament). For use with it he developed a complete electrical distribution system for light and power, including generators, motors, light sockets with the Edison base, junction boxes, safety fuses, underground conductors, and other devices. The crowning achievement of his work in this field was the Pearl St. plant (1881–82) in New York City, the first permanent central electric-light power plant in the world. He also built and operated (1880) an experimental electric railroad, and produced a superior storage battery of iron and nickel with an alkaline electrolyte. Other significant inventions include the Kinetoscope, or peep-show machine. Edison later demonstrated experimentally the synchronization of motion pictures and sound, and talking pictures were based on this work.

Free Essays on Thomas Edison Thomas Alva Edison is considered one of the greatest inventors in history. He was born in Milan, Ohio on February 11, 1847 and died in 1931. During his life he patented 1,093 inventions. Many of these inventions are in use today and changed the world forever. Some of his inventions include telegraphy, phonography, electric lighting and photography. His most famous inventions were the phonograph and the incandescent light bulb. Edison did some of his greatest work at Menlo Park. While experimenting on an underwater cable for the automatic telegraph, he found that the electrical resistance and conductivity of carbon varied accordingly to the pressure it was under. This was a major theoretical discovery, which enabled Edison to invent a â€Å"pressure relay† using carbon rather than magnets, which was the usual way to vary and balance electrical currents. In February of 1877 Edison began experiments designed to produce a pressure relay that would amplify and improve the audibility of the telephone, a device that Edison and others had studied but which Alexander Graham Bell was the first to patent, in 1876. By the end of 1877 Edison had developed the carbon-button transmitter that is still used today in telephone speakers and microphones. Many of Thomas Edison’s inventions including the carbon transmitter were in response to demands for new products and improvements. In 1877, he achieved his most unique discovery, the phonograph. During the summer of 1877 Edison was attempting to devise for the automatic telegraph a machine that would transcribe a signals as they were received into a form of the human voice so that they could then be delivered as telegraph messages. Some researchers had theorized that each sound, if it could be graphically recorded, would produce a distinct shape resembling short hand, or phonography, as it was known then. Edison hoped to make this concept real by employing a stylus-tipped carbon transmitter to make ... Free Essays on Thomas Edison Thomas Edison Thomas Alva Edison is one of America's most famous inventors. Edison saw huge change take place in his lifetime. He was responsible for making many of those changes occur. His inventions created and contributed to modern nightlights, movies, telephones, records and CDs. Edison was truly a genius. Edison is most famous for his development of the first electric light bulb. When Edison was born, electricity had not been developed. By the time he died, entire cities were lit by electricity. Much of the credit for electricity goes to Edison. Some of his inventions were improvements on other inventions, like the telephone. Some of his inventions he deliberately tried to invent, like the light bulb and the movie projector. But some inventions he stumbled upon, like the phonograph. Of all his inventions, Edison was most proud of the phonograph. Edison invented and improved upon things that transformed our world. Some things he invented by himself. Some things he invented with other people. Just about all his inventions are things we still use in some form today. Throughout his life, Edison tried to invent things that everyone could use. Edison created the world's first "invention factory". He and his partners invented, built and shipped the product - all in the same complex. This was a new way to do business. Today many businesses have copied Edison's invention factory design....

Winning Ideas to Create Research Articles

Winning Ideas to Create Research Articles Winning Ideas to Create Research Articles Research articles are made up of results achieved from conducting original research. These results can be obtained through either primary or secondary analysis.   Fundamental research involves collecting and capturing information directly from the source. Secondary research includes obtaining information from the previous researches done by others and recording it. The essential requirement of a research paper is to look for information relating to the topic, taking a stand/side on the issue and providing evidence for the position taken in an organized manner. The objective of the paper is the essence of a research paper.    A good research paper shows the findings of the research in a clear and concise manner without being mixed up by the wordplay of the author. A cook follows a written recipe to prepare a delicious meal. It is also the same with the author. There is a guideline/recipe that an author should use for him/her to have an interesting research paper. The following is a guideline to writing a good research paper. Selecting the Topic Choosing your topic is the first and the most crucial step in a research project. Before choosing a research topic, a student/author should ask himself/herself such questions: Has this topic been researched upon extensively? Is this topic unique and timely? Is it coherent with my career choice? A student should always choose a topic that he/she is interested. Whenever possible, the author needs to choose a topic that he/she is passionate about. For example, if you are interested in Business Management, write things that involve business issues or evolution of businesses. Do not deviate from your topic. Always consult with your friends and teachers about your chosen topic to get new ideas. If you realize that the topic you chose is not right for you, do not hesitate change. Researching the Topic After selecting a topic suitable for you, you should now start researching. Research can be done using several resources such as journal articles, web pages, books, posts on various blogs, interviews, newsletters, and magazines. You can also apply different online research methods that are well-known these days. Do not rely on one or two sources rather, use at least five sources. Books should be your primary tools to use when researching. Reading as much as you can will help you understand and connect things clearly. You will have the ability to see and seal any loopholes in your research. Analyze and Plan Every type of writing has its own approach. If your research becomes complicated for you, you can prepare a flowchart so that you can know all the stages in a sequence and prepare for them. Print out the research you have gathered online, highlight the key areas in the books you have read and read your research again. Identify if your research paper is argumentative or analytic. An argumentative research paper involves the author taking a side and arguing from that perspective. An analytic paper is prepared when the author freshly reviews an important issue. Lastly, the author should know his/her audience. If you are writing to people who are conversant with topic, you need not explain your ideas using theories. Preparing the Draft of a Research Article Organize your outline. Include in-text citations at the end of an important point. Depending on your paper requirements, follow the formatting guidelines in every part of your paper. You should acknowledge authors by citing your research paper. This is always mandatory. Inserting your citations properly will reduce the chances of your paper being rejected. Preparing the Final Draft Put aside your draft for a day before revising it for you to see any gaps. Rethink your ideas and organize again your paragraphs and sentences when revising. Read your paper out loud or have someone read it for you. Put it all together using the format authorized by your institution. Some universities have their unique way of formatting papers. Your supervisor should assist you by ensuring that the format is correct and the citations well placed before submission. To summarize, there are ten stages that experts go through to ensure that their research article is lovely and entertaining to their readers. The ten steps will help you in creating a hypothesis, testing your ideas and presenting your findings: First, always choose a topic that is right for you. You should enjoy studying and researching it. Secondly, plan your dissertation by creating an outline to organize and reasonably present ideas. Third, make use of transitions. This communicates to the readers that you are moving from one topic to another. Also separate your ideas using paragraphs. Two different ideas should not be put in one section instead, create a new paragraph for a different idea. Direct quotes should be included in your dissertation. They act as pieces of evidence from your sources. The direct quote should prove a point for your topic. Sixth, your paper should be formatted correctly with the help of your supervisor. Continue to write your draft so that it is error free. Ensure your research article has citations that are well placed. All sources should be cited. Create a desirable title for your article. Your topic should go hand in hand with your hypothesis. Lastly, form a memorable conclusion that should prove your point. At our service, we are committed to providing students with expert research paper writing help on different topics and disciplines.

Designing a performance appraisal system Essay Example | Topics and Well Written Essays - 2000 words

Designing a performance appraisal system - Essay Example While the exact nature of the goals may vary, some of the determined objectives would usually pertain to achieving a certain amount in sales, revenues and profits. There should also be measures in place to monitor and control the effectiveness and efficiency of every department. A performance appraisal system is one such management tool that would control the activities of managers, supervisors and subordinates throughout the entire organization. The task of creating and maintaining a performance appraisal system is usually one of the key tasks of the Human Resources Department and is also connected to the performance rewards and compensation system of the enterprise. Assumptions In the given scenario, I am working as an Occupational Psychologist and have been approached by a medium-sized organization called Select. The Managing Director has identified a need for a new performance appraisal system for senior and middle managers only, and he wants me to put together a proposal of how I would get this task done. The organization has 10 senior managers, 50 middle managers and 400 employees. The appraisal system will be conducted twice a year. Last appraisals using the current system were conducted one month ago. Competency frameworks are already available for the roles of senior and middle managers. ... Every organization no matter how big or small usually has a recap at least once a year in which it takes account of how well each department, division and how it as a whole has performed in terms of revenues, profits, market share, shareholder value or whatever other measure management deems as necessary and important to gauge performance (Brown, 2001). The truth is that we never know how well or badly we are doing at a certain task until we develop a measurement for it. A performance appraisal system enables us to measure how each employee, supervisor or manager is doing in the attainment of his or her objectives. In such a system, individual goals contribute to departmental goals, which in turn contribute to the overall goals of the enterprise. A performance appraisal or management system is a diverse, well thought out process that seeks to elicit cooperation from the workers in the pursuit and attainment of organizational goals, by using rewards like bonuses, increments and stock options for good performance and punishments or warnings for bad performance. In this way the manager or supervisor evaluates and lets the worker know how he or she is doing on the job (Fletcher, 2004). It has been observed that there are both positive and negative feelings about the initiation of a performance appraisal system in an organization. Employees who are not performing up to the mark and who are warned about their lackluster performance are likely to view the performance appraisal system as a nuisance and react negatively to attempts to correct undesirable behavior and put them back on track. On the other hand, employees who are exhibiting all the positive traits and performance are rewarded for their good behavior and are likely to treat the performance appraisal system as a

Financial accounting Research Proposal Example | Topics and Well Written Essays - 2750 words

Financial accounting - Research Proposal Example Asset Liabilities Equity Income Expenses. UNDERLYING ASSUMPTIONS Two core assumptions applied while making financial statements are: 1. Accrual Basis: Accrual basis of accounting record the revenues when realized and incur expense when they occur. All the income and expenses are recorded in the accounting record when they actually occur not at the time when cash has flown in or out of the business activity. Therefore in accrual base accounting all the records are reported in the financial statements in the period to which they relate to. Example: Following example adopted from Gibson, Charles H., 1998. Financial Statement Analysis: Using Financial Accounting Information, 7th Ed. South Western. Slight numerical values have been altered. Suppose: 1. Manufacturing concern sold merchandise for $15,000 on credit this year. This merchandise cost $900 when purchased last year. 2. It purchases inventory this year in the amount of $20,000 on credit. 3. Paid to suppliers f merchandise $13,000 this year. 4. Collects cash sales $7,000. Accrual Basis Cash Basis Sales $ 15,000 COGS $ 9,000 Income $ 6,000 Receipts (inflow) $ 7,000 Payment (outflow) $ 13,000 Loss ($ 6,000) It is seen that accrual basis shows a profitable position where else cash basis indicates a loss. Cash basis doesn't indicate the time period for the recognition of revenue and occurrence of cost. It shows the cash inflows and outflows. For this purpose separate statement is prepared whish shows the cash position and named as Statement of Cash flow. When using accrual basis of accounting,...The end users of the financial statements can be customers, investors, suppliers, government agencies, student body, economist or general public. The International Accounting Standard Board, a privately owned body based in London presented a document in July 1989 which became framework for the preparation & presentation of financial statements. On this framework all the IAS are based and determine the financial statement preparation and the information they contain. Accrual basis of accounting record the revenues when realized and incur expense when they occur. All the income and expenses are recorded in the accounting record when they actually occur not at the time when cash has flown in or out of the business activity. Therefore in accrual base accounting all the records are reported in the financial statements in the period to which they relate to. It is seen that accrual basis shows a profitable position where else cash basis indicates a loss. Cash basis doesn't indicate the time period for the recognition of revenue and occurrence of cost. It shows the cash inflows and outflows. For this purpose separate statement is prepared whish shows the cash position and named as Statement of Cash flow. Going concern assumption believes that business entities will remain in business for indefinite period of time. That the operations will continue in the future years.

The Sacred World of Imagination Essay Example | Topics and Well Written Essays - 1250 words

The Sacred World of Imagination - Essay Example The artificial animals are meaningless and superficial trappings. He worships any truly living animal as sacred. Still, in his quest for spiritual guidance, he is also forced to turn to the fraud and trickery of Mercerism. Do Androids Dream of Electric Sheep is a book that parodies man's superficial quest for religion through the fraud of animal worship and shows how man will even turn to inanimate objects for moral guidance. The story is told through the world of Rick Deckard. He is a bounty hunter who hunts down and kills the illegal Androids. The Rosen Corporation has built the new Nexus-6 robots so lifelike that they are almost undetectable. In a world where there is little that resembles life in the past, Deckard must seek out and destroy that which has the potential to replace it. The world has become splintered and alienated. People exist on the margins of life, outcast and distanced from any reality. Humans are segregated by health and kept at a distance from truth by the propaganda of the Android Buster Friendly's non-stop television show and the fraudulent religion of Mercerism. Having destroyed nearly all of the original creation, man must now decide which of his own replacements are good and which are evil. The story of morality is told through the animal kingdom. Animals are the one constant that everyone has a connection to. ... The Sidney's Catalogue has become the new bible, carried wherever they go and looked to for truth and guidance. When an animal that appears to be real confuses Rick he states his belief in Sidney's. He says, "Sidney's never makes a mistake. We know that too. What else can we depend on" (p.41). The bounty hunter that was trying to eliminate the false humans from earth was also dedicated to finding the only true animals left on the planet. Syndey's had become his bible. Virtue was evaluated by man's treatment and care of the animals he owned and knew. When Deckard was trying to purchase a horse from his neighbor, his neighbor rebuffed his request. Barbour, the neighbor said, "It would be immoral to sell my horse" (p.10). Deckard replied, "Sell the colt, then. Having two animals is more immoral than not having any" (p.10). Deckard and his neighbor were in a tug of war over the contention that there was a proper and moral responsibility to owning an animal. It did not involve the treatment of the animal, only the ownership. Ownership of one animal was righteous, more was gluttonous, and less was depraved. In Dick's book, animals were elevated to the elite level of ethics and Godliness. To know an appreciation for an animal was to make you a better human being. When John Isadore was returning to the pet repair shop to have what he believed was a robotic cat recharged, the cat expired. He was glad that it had died and now he "...no longer had to listen to the nerve wracking wheezing of the construct: he could relax" (p.72). Animals, and especially robotic ones, did not move Isadore. The war had left Isadore mentally challenged and he had been, "...reduced to this ignomous task with its attendant emotional by-products" (p.72). His mind had been reduced and

Feedback and its importance Essay Example | Topics and Well Written Essays - 500 words

Feedback and its importance - Essay Example in organizations) or in universities. Since the key objective of providing feedbacks is to inform the individuals concerned regarding their performance, and give them objective opinions, it helps them to understand their strengths and weaknesses and utilize their capabilities to the optimum, and hence pave way for self-growth. Furthermore, feedback helps in identifying the problem areas or areas of concern and develops ways to overcome the shortcomings. For instance, in terms of organizational learning, the managers periodically evaluate the job performance of their workers and employees, and provide them feedback on the basis of a thorough assessment. Such an assessment can then be used by the workers to identify gaps in their performance and use the same to increase their productivity (Anderson 1990; Kluger & Denisi 1996). Similarly, feedback in universities, which are given in the form of grades or critique of their work, helps the students in identifying the areas in which they e xcel and those where they need to put in more effort. Various schools and universities also enable teacher feedback, whereby the students assess the performance of their teachers. It is only through feedback, that any substantial and positive change can be hoped to be achieved.

The contribution of the construction industry to economic development Essay

The contribution of the construction industry to economic development in Libya - Essay Example Such estimates signifying the role of construction industry in the national economies, especially in the context of developing economies, could rise further as these figures do not include the informal sectors. In developing economies informal sectors generates significant casual employment in both rural and urban areas (Ganesan 2000). The construction outputs are considered as a major constituent of investment and part of fixed capital which are essential for continuous and sustainable economic growth. In the normal course the outcomes of construction activities produce results that benefits on the whole for a larger period of time. Construction industry is also very important since infrastructure development is very crucial and a pre condition for potential economic growth (Ive and Gruneberg, 2000; Hillebrandt 2000). The importance of the construction industry is due to the role it has in the economy, but that role varies between nations. In developing countries, the construction industry has a pivotal role in providing a significant infrastructure in the form of roads, railways, hospitals, schools, airports, housing and other buildings. In developed countries the emphasis is on professional services, maintenance and repair constructions (Ruddock, 2009; Bon, 1999).The main purpose of this study is to draw attention to the importance of the construction industry in Libya through investigating its relationship with other sectors via linkages which are defined as â€Å"backward and forward linkages† (Raza, 2008- p no?). The construction industry stimulates the growth of other sectors through a complex system of linkages which are defined as backward and forward – directions from an input and output model of the economy. Changes in construction industry usually affect other sectors through its linkages. Therefore, its highest linkages with other sectors provide a more rapid growth in the economy (Song, Liu, 2006). As a matter of fact the backward

Sociology - (Classical theorist Marx) Give an account of how Marx Essay

Sociology - (Classical theorist Marx) Give an account of how Marx understood History - Essay Example But was Karl Marx, sometimes in collaboration with friend and political economist, Friedrich Engels (1820-1895) who revolutionized the relationship of material production and the role of human beings within social structures. He devoted a good part of his time to economic studies on the flaws of the capitalist society; and produced some famous works like the ‘Communist Manifesto’ (1848) and ‘Das Capital’ (1867), with one aim: the self-emancipation of the working class. Hegel (1770-1831) and Ludwig Feuerbach (1804 -1872) are two theorists who affected Marx very strongly. The concept of Historical Materialism: In his ‘Introduction to Theses On Feuerbach’ (1845), Marx commences his own distinctive posit on Materialism, based on Feuerbach’s critique of Hegel’s ‘Theory of the Right’ (1821).His view of history is very different from the others. Marx, states that â€Å"it is not the consciousness of men that determines their being, but, on the contrary, their social being that determines their consciousness (Marx and Engels, 1859: pp 503-504). According to Hegel (1821), God created everything from Him, thus ‘God’ was the ‘Absolute Idea’. Then, due to the nature of the material world opposing God, the ‘negation’ or ‘alienation’ from God occurred; this was a dialectic or a clash of opposite forces; until a third stage of the growth of man’s consciousness, would reconcile with the ‘Absolute Idea’ and return to a state of original consciousness. It had at its centre that all events are predetermined by God. Feuerbach (1841) argued that, the faculty of thought, which is the property of human beings, was the ruling principle of existence, and not God, as theorized by Hegel, and love was what united them. Marx, while agreeing with Hegel in part by accepting the ‘clash of opposing forces’ notion, he rejected Hegel’s view of the ‘Absolute Idea’. Marx posited that ‘labour’ was the ‘essence

Policies Related to Environmental Concerns Essay Example for Free

Policies Related to Environmental Concerns Essay While, indeed, there are several legal statutes that are heralded by both the international, national, and local levels of the public communities, especially the government, there remains much contention with regard to the true cost of ratifying it and adhering to its implementation. This is a dilemma that occurs to be of special truth to the developing countries who are not given the luxury of financial and technological resources to address the issues associated with the environment. Definitely, there are a lot of issues and related costs that are borne with every legal statute passed for the purpose of protecting the environment. From the implantation of it come the associated resources in terms of manpower and other needs. Over time, it has been the case that the cost of the environmental degradation that occurred, and is still occurring, becomes harder to quantify in financial terms. The costs are usually measured and derived from air and water quality as examples (Ahmed Sanchez-Triana, 2008). However, it should be noted that it is not the financial quantification of this particular endeavor that matters but the present impact and the long-term goals that should be foreseen. First, it is seen that the adverse effects brought about by the inability of the environment to keep with the needs of the human population is already being felt by people. There are different groups that can be identified in terms of the socio-economic classes to which they belong and the degree to which they are disadvantaged because of certain characteristics. The benefits that could be derived from the simple laws that protect their basic needs such as the access to clean water vary from one group to another. Another consideration for this is that the impacts have led to a domino-effect where it has indirectly affected the entire society and should the provision of safety nets through legal policies are definitely an urgent need to solve several interlocking problems that have come in lieu of the environmental degradation. Second, the long-term effects brought about by the legal statutes would definitely help not only the generations in immediate succession of the present but would also last until a few more decades, if not centuries (Gillespie, 1997). Every little act of kindness done to the environment in the present contributes to its well-being and existence in the future. This is among the elements that link the past to the present and the present to the future. References Ahmed, K. Sanchez-Triana, E. (2008).

Analysing Types Of Collection System Engineering Essay

Analysing Types Of Collection System Engineering Essay Based on their mode of operation, collection systems are classified into two categories: hauled-container systems and stationary-container systems. Hauled-Container Systems (HCS): Collection systems in which the containers used for the storage of wastes are hauled to the processing, transfer, or disposal site, emptied, and returned to either their original location or some other location are defined as hauled-container systems. There are two main types of hauled-container systems: (1) tilt-frame container and (2) trash-trailer. The collector is responsible for driving the vehicle, loading full containers and unloading empty containers, and emptying the contents of the container at the disposal site. In some cases, for safety reasons, both a driver and helper are used. Systems that use tilt-frame-loaded vehicles and large containers, often called drop boxes, are ideally suited for the collection of all types of solid waste and rubbish from locations where the generation rate warrants the use of large containers. Open-top containers are used routinely at warehouses and construction sites. Large containers used in conjunction with stationary compactors are common at commercial and industrial services and at transfer stations. Because of the large volume that can be hauled, the use of tilt-frame hauled container systems has become widespread, especially among private collectors servicing industrial accounts. The application of trash-trailers is similar to that of tilt-frame container systems. Trash-trailers are better for the collection of especially heavy rubbish, such as sand, timber, and metal scrap, and often are used for the collection of demolition wastes at construction sites. Stationary-Container Systems (SCS): Collection systems in which the containers used for the storage of wastes remain at the point of waste generation, except when moved for collection are defined as stationary-container systems. Labor requirements for mechanically loaded stationary-container systems are essentially the same as for hauled-container systems. There are two main types of stationary-container systems: (1) those in which self-loading compactors are used and (2) those in which manually loaded vehicles are used. Because a variety of container sizes and types are available, these systems may be used for the collection of all types of wastes. The major application of manual transfer and loading methods is in the collection of residential wastes and litter. Manual methods are used for the collection of industrial wastes where pickup points are inaccessible to the collection vehicle. Collection Routes: Once the equipment labor requirements have been determined, collection routes must be laid out so both the work force equipment are used effectively. In general, the layout of collection routes is a trial-and-error process. There are no fixed rules that can be applied to all situations. Some of the factors that should be taken into consideration when laying out routes are as follows:(1) existing company policies and regulations related to such items as the point of collection and frequency of collection must be identified, (2) existing system conditions such as crew size and vehicle types must be coordinated, (3) wastes generated at traffic-congested locations should be collected as early in the day as possible, (4) sources at which extremely large quantities of wastes are generated should be serviced during the first part of the day, and (5) scattered pickup points where small quantities of solid wastes are generated should, if possible, be serviced during one trip or on the same day, if they receive the same collection frequency. Layout of Routes: The layout of collection routes is a four-step process. First, prepare location maps. On a relatively large-scale map of the area to be serviced, the following data should be plotted for each solid-waste pickup point: location, number of containers, collection frequency, and, if a stationary-container system with self-loading compactors is used, the estimated quantity of wastes to be collected at each pickup location. Second, prepare data summaries. Estimate the quantity of wastes to be collected from pickup location serviced each day that the collection operation is to be conducted. Where a stationary-container system is used, the number of locations that will be serviced during each pickup cycle must also be determined. Third, lay out preliminary collection routes starting from the dispatch station or where the collection vehicles are parked. A route should be laid out that connects all the pickup locations to be serviced during each collection day. The route should be laid out so that the last location is nearest the disposal site. Fourth, develop balanced routes. After the preliminary collection routes have been laid out, the haul distance for each route should be determined. Next, determine the labor requirements per day and check against the available work times per day. In some cases it may be necessary to readjust the collection routes to balance the work load and the distance traveled. After the balanced routes have been established, they should be drawn on the master map. Schedules: A master schedule for each collection route should be prepared for use by the engineering department and the transportation dispatcher. A schedule for each route, on which can be found the location and order of each pickup point to he serviced, should he prepared for the driver. In addition, a route book should be maintained by each truck driver. Transfer and transport: The functional element of transfer and transport refers to the means, facilities, and appurtenances used to effect the transfer of wastes from relatively small collection vehicles to larger vehicles and to transport them over extended distances to either processing centers or disposal sites. Transfer and transport operations become a necessity when haul distances to available disposal sites or processing centers increase to the point that direct hauling is no longer economically feasible. Transfer Station: Important factors that must be considered in the design of transfer stations include: type of transfer operation to be used, (2) capacity requirements, (3) equipment and accessory requirements, and (4) environmental requirements. Type of Transfer Station: Depending on the method used to load the transport vehicles, transfer stations may be classified into three types: direct discharge, storage discharge, and combined direct and storage discharge. Direct Discharge: In a direct-discharge transfer station, wastes from the collection vehicles usually are emptied directly into the vehicle to be used to transport them to a place of final disposition. To accomplish this, these transfer stations usually are constructed in a two-level arrangement. The unloading dock or platform from which wastes from collection vehicles are discharged into the transport trailers is elevated, or the transport trailers are located in a depressed ramp. Direct-discharge transfer stations employing stationary compactors are also popular. Typical direct discharge transfer station Storage Discharge: In the storage-discharge transfer station, wastes are emptied either into a storage pit or onto a platform from which they are loaded into transport vehicles by various types of auxiliary equipment. In a storage-discharge transfer station, the storage volume varies from about one-half to two daysà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ volume of wastes. Typical storage discharge transfer station Combined Direct and Storage Discharge: In some transfer stations, both direct-discharge and storage-discharge methods are used. Usually, these are multipurpose facilities designed to service a broader range of users than a single-purpose facility. In addition to serving a broader range of users, a multipurpose transfer station can also house a materials-salvage operation. Capacity Requirements: The operational capacity of a transfer station must be such that the collection vehicles do not have to wait too long to unload. In most cases, it will not be cost- effective to design the station to handle the ultimate peak number of hourly loads. An economic trade-off analysis should be made between the annual cost for the time spent by the collection vehicles waiting to unload against the incremental annual cost of a larger transfer station and/or the use of more transport equipment. Because of the increased cost of transport equipment, a trade-off analysis must also be made between the capacity of the transfer station and the cost of the transport operation, including both equipment and labor components. Equipment and Accessory Requirements: The types and amounts of equipment required vary with the capacity of the station and its function in the waste-management system. Specifically, scales should be provided at all medium and large transfer stations both to monitor the operation and to develop meaningful management and engineering data. Environmental Requirements: Most of the large, modern transfer stations are enclosed and are constructed of materials that can be maintained and cleaned easily. For direct-discharge transfer stations with open loading areas, special attention must be given to the problem of blowing papers. Wind screens or other barriers are commonly used. Regardless of the type of station, the design and construction should such that all accessible areas where rubbish or paper can accumulate are eliminated. Location of Transfer Station: Whenever possible, transfer stations should be located (1) as near as possible to the weighted center of the individual solid-waste production areas to be served, (2) within easy access of major arterial highway routes as well as near secondary or supplemental means of transportation, (3) where there will be a minimum of public environmental objection to the transfer operations, and (4) where construction and operation will be most economical. Additionally, if the transfer- station site is to be used for processing operations involving materials recovery and/or energy production, the requirements for those operations must be considered. Transfer Means Methods: Motor vehicles, railroads, and ocean-going vessels are the principal means now used to transport solid wastes. Pneumatic and hydraulic systems have also been used. Motor Vehicle Transport: Motor vehicles used to transport solid wastes on highways should satisfy the following requirements: (1) the vehicles must transport wastes at minimum cost, (2) wastes must be covered during the haul operation, (3) vehicles must be designed for highway traffic, (4) vehicle capacity must be such that allowable weight limits are not exceeded, and (5) methods used for unloading must be simple and dependable; The maximum volume that can be hauled highway transport vehicles depends on the regulations in force in the state in which they are operated. Methods used to unload the transport trailers may be classified according to whether they are self-emptying or require the aid of auxiliary equipment. Self-emptying transport trailers are equipped with mechanisms such as hydraulic dump beds, powered diaphragms or moving floors that are part of the vehicle. Moving-floor trailers are an adaptation of equipment used in the construction industry. An advantage of the moving-floor trailer is the rapid turnaround time (typically 6 to 10 mm) achieved at the disposal site without the need for auxiliary equipment. Unloading systems that require auxiliary equipment are usually of the à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"pull-offà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚  type, in which the wastes are pulled out of the truck by either a movable bulkhead or wire-cable slings placed forward of the load. The disadvantage of requiring auxiliary equipment and work force to unload at the disposal site is relatively minor in view of the simplicity and reliability of these metho ds. Another auxiliary unloading system that has proved very effective and efficient involves the use of movable, hydraulically operated tipping ramps located at the disposal site. Operationally, the semitrailer of a tractor-trailer- trailer combination is backed up onto one of the tipping ramps; the tractor-trailer combination is backed up onto a second tipping ramp. The backs of the trailers are opened, and the units are then liked upward until the wastes fall out by gravity. The time required for the entire unloading operation typically is about 5 mm/trip. Large-capacity containers and container trailers are used in conjunction with stationary compactors at transfer stations. In some cases, the compaction mechanism is an integral part of the container. When containers are equipped with a self-contained compaction mechanism, the movable bulkhead used to compress the wastes is also used to discharge the compacted wastes. Railroad Transport: Although railroads were commonly used for the transport of solid wastes in the past, they are now used by only a few communities. However, renewed interest is again developing in the use of railroads for hauling solid wastes, especially to remote areas where highway travel is difficult and railroad lines now exist. Water Transport: Barges, scows, and special boats have been used in the past to transport solid wastes to processing locations and to seaside and ocean disposal sites, but ocean disposal is no longer practiced by the United States. Although some self-propelled vessels (such as United States Navy garbage scows and other special boats) were once used, the most common practice was to use vessels towed by tugs or other special boats. Pneumatic Transport: Both low-pressure air and vacuum conduit transport systems have been used to transport solid wastes. The most common application is the transport of wastes from high-density apartments or commercial activities to a central location for processing or for loading into transport vehicles. The largest pneumatic system now in use in the United States is at the Walt Disney World amusement park in Orlando, Florida.
