Many People Are Villainous In The Way They Act, And Their Villainous A

Many people are villainous in the way they act, and their villainous acts may be rooted in the desire to destroy others, or in the hopes of elevating themselves. Many people may only act "villainous" in reaction to the way they have been treated in the past. Shylock the Jew is the villain or antagonist in the play .The Merchant of Venice.. Shylock mistreats Antonio the Christian, his daughter, Jessica and Launcelot. The first person Shylock mistreats, is Launcelot. He mistreats this servant by complaining behind Launcelot's back of his laziness. Shylock says, "The patch is kind enough, but a huge feeder, Snail-slow in profit, and he sleeps by day More than the wildcat. Drones hive not with me.. ..His borrowed purse." 1 Shylock also acts villainous towards Launcelot by acting belligerent towards him. "Who bids thee call? I do not bid thee call." 2 Shylock mistreats this man because of his poverty, and because Launcelot is socially beneath him. You also start to wonder about how fair Shylock is, when Launcelot is deciding whether or not to leave him. Shylock also mistreats his own daughter, Jessica. He mistreats her by keeping her as a captive in her own house, not letting her out, and not letting her hear the Christian music around her. He orders her to: "Lock up my doors; and when you hear the drum... ..But stop my house's ears-I mean casements. Let not the sound of shallow fopp'ry enter My sober house." 3 Jessica considers her home to be hell, and she calls Launcelot, a "merry little devil". She even states that her father is Satan. Shylock also mistreats his own daughter, by not loving her enough, even to the point where he complains about all of the money he's spending in a search to find her. "Why, there, there, there, there! A diamond gone cost me two thousand ducats in Frankford! The curse.. ..ill luck stirring but what lights o' my shoulders; no sighs but o' my breathing; no tears but o' my shedding."4 Salerio makes the audience wonder about Shylock, when he raves about when Shylock was calling out, "Oh my ducats, my daughter, my ducats, my daughter.." This makes you wonder which he misses the most. This proves that he mistreats, even his own daughter. He values his money more than his own blood. Shylock mistreats Antonio. He does so by talking behind Antonio's back, and he reveals his hatred of Antonio, when he says, "How like a fawning publican he looks! I hate him for he is a Christian; But more for that...Cursed be my tribe If I forgive him!" 5 Shylock feels justified in exacting revenge for all the ills Antonio causes him. He then draws up an unbelievable bond. He blames Antonio for all of his problems, even his race's problems are blamed on people like Antonio, and he feels Christians have persecuted his race when he says, "To bait fish withal. If it will feed nothing else, it will feed my revenge...The villainy you teach me I will execute, and it shall go hard but I will better the instruction." 6 He shows that he will copy the example of Christians. Shylock becomes the true villain when he atkes Antonio to court. These actions prove that Antonio is mistreated by Shylock, the villain. Shylock is the villain of .The Merchant of Venice.. He mistreats too many people, and then asks for mercy in a court. Shylock is mad for revenge towards all Christians, especially Antonio. He is such a villain that even his daughter and servant are eager to escape him. Villains are oftenly antagonists in story plots and normally are a threat to the main character. Villains normally have motives behind their evil doings. Endnotes: 1. Shakespeare, William. .Merchant of Venice..

Wind Energy the Indian Scenario Essays

Wind Energy the Indian Scenario Essays Wind Energy the Indian Scenario Essay Wind Energy the Indian Scenario Essay In 2008, India was the country that brought online the third largest amount of wind energy, after the US and China, and it now ranks fifth in total installed capacity with 10,925 MW of wind power installed at the end of 2009. A strong domestic manufacturing base has been main underlying factor for the growth of the Indian wind energy market. The Indian wind turbine manufacturer Suzlon is now a recognized player on the global market, and many international companies are established in India. India has a great untapped potential for wind energy. According to official estimates, the country’s total wind energy resource amounts to 48 GW of commercially viable capacity, but some experts think that this figure is on the conservative side, and that technological improvements could significantly increase this potential. The positive development of wind energy in India has mainly been driven by progressive state level legislation, including policy measures such as renewable portfolio standards and feed-in-tariffs. At the moment, there is no coherent national renewable energy policy to drive the development of wind energy. This is urgently needed to realize the country’s full potential and reap the benefits for both the environment and the economy. The Indian government is currently considering the introduction of a national renewable energy policy, so this report comes as a timely reminder of how important a role wind energy could play in securing India’s energy security, curbing its CO2 emissions, providing new employment and boosting economic development. The Indian wind industry, both domestic and international, stands ready to do its part in achieving an energy revolution in India. With sufficient political will and the right policy frameworks, it could do even more. This paper gives a brief on the history of wind energy in India, the current state of production, the major policies that are guiding the industry at the moment and also suggests a way forward for the industry. 1) RENEWABLE ENERGY SCENARIO IN INDIA : In the early 1980s, the Indian government established the Ministry of Non-Conventional Energy Sources (MNES) to encourage diversification of the country’s energy supply, and satisfy the increasing energy demand of a rapidly growing economy. In 2006, this ministry was renamed the Ministry of New and Renewable Energy (MNRE). Renewable energy is growing rapidly in India. With an installed capacity of 16. 4 GW, renewable energy sources (excluding large hydro) currently account for 7. 7 % of India’s overall power generation capacity. By 2012, the Indian government is planning to add an extra 14 GW of renewable sources. In its 10th Five Year Plan, the Indian government had set itself a target of adding 3. 5 GW of renewable energy sources to the generation mix. In reality, however, nearly double that figure was achieved. In this period, more than 5. 4 GW of wind energy was added to the generation mix, as well as 1. 3 GW from other RE sources. The target set for the period from 2008-2012 was increased to 14 GW, 10. 5 GW of which to be new wind generation capacity. In India the average life of a wind power generator is between 20-25 years. The Indian Ministry of New and Renewable Energy (MNRE) estimates that there is a potential of around 90,000 MW for power generation from different renewable energy sources in the country, including 48,561 MW of wind power, 14,294 MW of small hydro power and 26,367 MW of biomass. Hence, it can be seen that wind forms the major chunk of renewable energy portfolio in India that is estimated to be tapped in the coming years ahead and hence it forms an important part of study at the present moment. 2) WHY IS WIND SO IMPORTANT? It is well known that wind is certainly an inexhaustible abundant source of energy which is caused by the differential solar radiation on the Earth’s geo-diverse surfaces, having different degrees of absorption, reflection, refraction, convection and transmission. Wind power is the most established amongst the renewable energy sources. Wind power can be generated on a large scale compared to solar and other renewable sources and hence it becomes commercially viable. Wind mills are easy to install and require much less area compared to solar power per MW. Wind being a renewable energy free from any kind of combustion, is a very clean source of energy with zero GHG emissions. This implies that capacity addition in wind power will help in reducing the carbon footprint at the same time closing the gap between demand and supply of power in the country. It also results in significant saving of potable/drinking water, which is much needed for human survival. Electricity generation by wind consumes only 1/200th or 1/400th of water that is used by nuclear, oil or coal. But we also need to be clear that a country like ours with such a long coast line need not necessarily be having economic/technical potential for wind power with its diurnal variations of land breeze/sea breeze. At the other extreme the mere occurrence of good monsoon or frequency of cyclones amp; hurricanes may not provide an economical viability or a technical feasibility of wind power. 3) HISTORICAL PERSPECTIVE OF WIND POWER IN INDIA : Recognizing the importance of tapping renewable energy sources for power generation, India has been working in this direction for more than two decades. The Government of India realized the importance of private sector participation in the wind power sector as early as 1983/84. Accordingly, a national programme was initiated to tap the then estimated potential of 20000 MW by adopting a market-oriented strategy. This ultimately led to successful commercial development of wind power technology and substantial additions to power generation capacity in the country. Significant progress made in this sector was the result of policy support measures and incentives announced by the government for implementing the latest wind energy technologies and encouraging private entrepreneurs to take up commercial projects. After the announcement of the ‘Private Power Policy’ in 1991, an increase in the private sector participation was observed in the field of wind energy. This, along with a booming economy and the attractive fiscal incentives, provided the impetus for accelerated growth of the wind power sector as shown in ‘Figure 1’ below. FIGURE 1 – GROWTH OF WIND POWER IN INDIA (INSTALLED CAPACITY IN MW / YEAR VS YEAR) After a brief downturn between 1996 amp; 1998, the scenario started looking up in 1999 and this upswing is still continuing. The main factors that have contributed to this positive growth are: a) Technological maturity and introduction of machines, suitable for the Indian conditions (e. g. wind turbines designed for low wind regimes) that resulted in overall higher capacity utilization. This factor helped in attracting more investments from the private sector. ) Introduction of bigger capacity and more cost-effective wind turbines. c) Better site selection due to more sophisticated and rigorous wind resource assessment and micro siting. d) Conducive policy regime introduced by some states (Maharashtra was one such state that came out with an investor friendly package, including attractive power purchase prices). 4) WIND ENERGY POTENTIAL IN INDIA : The total potential for wind power in India was first estimated by the Centre for Wind Energy Technology (C-WET) at around 45 GW, and was recently increased to 48. GW. This figure was also adopted by the government as the official estimate. The C-WET study was based on a comprehensive wind mapping exercise initiated by MNRE, which established a country-wide network of 1050 wind monitoring and wind mapping stations in 25 Indian States. This effort made it possible to assess the national wind potential and identify suitable areas for harnessing wind power for commercial use, and 216 suitable sites have been identified. However, the wind measurements were carried out at lower hub heights and did not take into account technological innovation and improvements and repowering of old turbines to replace them with bigger ones. At heights of 55-65 meters, the Indian Wind Turbine Manufacturers Association (IWTMA) estimates that the potential for wind development in India is around 65-70 GW. The World Institute for Sustainable Energy, India (WISE) considers that with larger turbines, greater land availability and expanded resource exploration, the potential could be as big as 100 GW. ) STATE WISE DISTRIBUTION OF WIND POWER GENERATION CAPACITY : FIGURE – 2 (C-WET’s WIND POWER DENSITY MAP) Table 1 – Installed Capacity per state (MW) State| March 2010| March 2009| March 2008| March 2007| March 2006| March 2005| Tamilnadu| 4907| 4304. 5| 3873. 4| 3492. 7| 2894. 6| 2037| Karnataka| 1473| 1327. 4| 1011. 4| 821. 1| 584. 5| 410. 7| Maharashtra| 2078| 1938. 9| 1755. 9| 1487. 7| 1001. 3| 456. 2| Rajasthan| 1088| 738. 4| 538. 8| 469. 8| 358. 1| 284. 8| Andhra Pradesh| 236| 122. 5| 122. 5| 122. | 121. 1| 120. 6| Madhya Pradesh| 229| 212. 8| 187. 7| 57. 3| 40. 3| 28. 9| Kerala| 28| 27. 0| 10. 5| 2| 2| 2| Gujarat| 1864| 1566. 5| 1252. 9| 636. 6| 338| 253| Others| 4| 1. 1| 1. 1| 1. 1| 1. 1| 1. 1| Total| 11807| 10242. 3| 8754. 0| 7090. 8| 5341| 3594. 3| The Wind Resource Assessment Programme carried out in India to reassess the wind potential was one of the largest programmes of its kind in the world, covering around 900 wind monitoring and mapping stations in 24 states and Union Territories. So far 208 potential sites have been identified in 13 states. As per Table 1, states with high wind potential include Tamil Nadu, Gujarat, Andhra Pradesh, Karnataka, Kerala, Madhya Pradesh, and Maharashtra. It is proposed to prepare an Indian Wind Atlas by using state-of-the-art software like WASP (Wind Atlas Analysis and Application Programme) on GIS platform. This will encourage the rapid growth of wind energy in India. The map shown here indicates where WASP has been applied. WASP has been used to establish national wind atlases for the ‘red’ countries and WASP has been applied for regional and local studies in the ‘blue’ countries. 6) OFF-SHORE WIND POTENTIAL IN INDIA : Offshore wind development zones are generally considered to be ten kilometers or more from land. Offshore wind turbines are less obtrusive than turbines on land, as their apparent size and noise is mitigated by distance. Because water has less surface roughness than land (especially deeper water), the average wind speed is usually considerably higher over open water. Capacity factors (utilization rates) are considerably higher than for onshore and near shore locations. Transporting large wind turbine components (tower sections, nacelles, and blades) is much easier over water than on land, because ships and barges can handle large loads more easily than trucks/lorries or trains. On land, large goods vehicles must negotiate bends on roadways, which fixes the maximum length of a wind turbine blade that can move from point to point on the road network; no such limitation exists for transport on open water. Offshore wind turbines will probably continue to be the largest turbines in operation, since the high fixed costs of the installation are spread over more energy production, reducing the average cost. Turbine components (rotor blades, tower sections) can be transported by barge, making large parts easier to transport offshore than on land, where turn clearances and underpass clearances of available roads limit the size of turbine components that can be moved by truck. Similarly, large construction cranes are difficult to move to remote wind farms on land, but crane vessels easily move over water. Offshore wind farms tend to be quite large, often involving over hundreds of turbines. CWET (Centre for Wind Energy Technology) has taken some initial efforts to survey the potential in the field of off-shore wind power generation. A working group consisting of expert members from National Institute of Ocean Technology (NIOT), Indian Institute of Technology Madras (IITM), Nuclear Power Corporation of India Limited (NPCIL), National Thermal Power Corporation (NTPC), Indian Oil Corporation (IOCL) and C-WET had, in late 2008 or 2009, started studies for feasibility of offshore wind measurements. The team had initiated the work on getting the clearances for offshore measurements near Dhanushkoti ( close to Rameswaram ). For a project planning to kick start offshore wind measurements, the team visited Dhanushkoti and collected the GPS co-ordinates with the help of land surveyors. The main objective was to take up wind resource assessment studies in the southern tip of India, particularly at two locations viz. Koodankulam (Kanyakumari) and Rameshwaram (Dhanuskodi), and to examine the feasibility for setting up offshore wind farms. The aim was to collect data set of wind speeds, wind direction and to gather sea temperature, sea current characteristics, and waves data for environmental research, design, and development of offshore wind farms, and to assess potential impacts of these measured parameters on the wind farms etc. Some preliminary data suggests that the wind power densities are about 250–300 W/m2 by the Arabian Sea (6-6. 4 m/s), 250–600 W/m2 (6-7. 8 m/s) by the Indian Ocean, and 150–500 W/m2 (5. 1-7. 4) by the Bay of Bengal (Rameswaram area). A minimum wind speed of about 6. 5 m/s is required for offshore wind farms, and as suggested earlier, many regions in Northern Europe oceans have wind speeds much in excess of 6. 5 m/s. The data presented earlier indicates that India is not blessed with such high offshore wind speeds. Sadly, on the corporate side, there have been few, if any, efforts on offshore wind. The only piece of news that indicated some corporate interest was from the Oil and Natural Gas Corporation (ONGC), when, in April 2009, it announced its plans to tap offshore wind energy. After setting up its first 50 MW onshore wind energy farm in Gujarat, ONGC announced it was planning to tap offshore wind potential. In this context, ONGC held a series of meetings and collected a myriad of data related to offshore wind potentials. The company had mentioned at the time that a detailed study would be conducted to find out the viability of this offshore project. However, after this announcement, little detail has been forthcoming on this. These are all the data I have on offshore wind developments and progress in India. As per the latest data available, the cumulative offshore installed capacity globally stood at 1,421 MW as of 2007 and this figure is expected to rise to 12,000MW by the year 2013. 7) POLICY ENVIRONMENT FOR WIND ENERGY IN INDIA : The Indian government’s stated target is for renewable energy to contribute 10% of total power generation capacity and have a 4-5% renewable energy share in the electricity mix by 2012. This means that renewable energy would grow at a faster rate than traditional power generation, accounting for around 20% of the total added capacity planned in the 2008-2012 timeframe. Some of the important policies that are allowing this sector to grow are listed below. The Electricity Act 2003: The Electricity Act required the SERCs to set Renewable Portfolio Standards for electricity production in their state. Following this, the Ministry for New and Renewable Energy (MNRE) issued guidelines to all state governments to create an attractive environment for the export, purchase, wheeling and banking of electricity generated by wind power projects. Some important policy measures for wind power in India are: * Fiscal and financial incentives : * 80% accelerated depreciation over one or two years 10 year income tax holiday for wind power generation projects * Excise duty relief on certain components * Some states have also announced special tariffs, ranging from Rs 3-4 per kWh, with a national average of around Rs 3. 50 per kWh * Wheeling, banking and third party sales, buy-back facility by states * Guarantee market through a specified renewable portfolio standard in some states, as decided by the state electricity regulator by way of power purchase agreements * Reduced wheeling charges as compared to conventional energy. * Land Policies : The Ministry of Environment and Forests has issued guidelines for diversion of forest lands for non-forest purposes, particularly to enable wind generation. * Clearance of leasing and forest land for up to a period of 30 years for wind developers. * Financial assistance : * Setting up of the Indian Renewable Energy Development Agency (IREDA), the premier finance agency of the Government of India to provide soft loans for renewable energy projects, particularly for demonstration and private sector projects. * Wind resource assessment: * The government set up the Centre for Wind Energy Technology (C-WET) to map wind energy potentials. The C-WET has set up more than 1,000 wind monitoring and wind mapping centers across 25 states. * Wind mapping at 50 meters (C-WET) and 60-80 meters height (private companies) * F eed in tariff and Generation Based Incentive (GBI) : MNRE has decided to incentivise actual energy generation rather than only capacity addition. To achieve this task, it has been proposed that power producers shall be given some incentive on every unit generated over and above the feed in tariff approved by particular state. Scheme for implementation for GBI for grid interactive power projects: * Objectives : ) To broaden the investor base and create a level playing field between various classes of investors. b) To incentivize higher efficiencies with the help of a generation/outcome based incentive. c) To facilitate entry of large independent power producers and foreign direct investors to the wind power sector. * Incentive and Duration: Under the  Ã‚   scheme, a GBI will be provided to wind electricity producers   @ Rs. 0. 50 per unit of electricity fed into the grid for a period not less than 4 years and a maximum period of 10 years in parallel with accelerated depreciation on a mutually exclusive manner, with a cap of Rs. 2 lakhs per MW. The total disbursement in a year will not exceed one fourth of the maximum limit of the incentive i. e. Rs. 15. 50 lakhs per MW during the first four years. Utilization of Wind Energy in India : Despite the high installed capacity, the actual utilization of wind power in India is low because policy incentives are geared towards installation rather than operation of the plants. This is why only 1. 6% of actual power production in India comes from wind although the installed capacity is 6%. The government is considering the addition of incentives for ongoing operations of the installed wind power plants. Table 2 gives a detailed picture of the current tariff rates offered by the states in which wind power is currently being generated and it also highlights the future price escalation mechanism proposed by each state. An inference that can be drawn from this data is that the majority of the states do not propose a tariff escalation for the next 10-20 years, and as the tariff rates are competitive to power conventionally generated from the grid through fossil fuels, we could say that this is a positive step in ensuring further participation and growth in wind power generation. TABLE 2 State Tariff Rates and Price Mechanisms Some State Policy Incentives : * Energy Buyback , power wheeling and banking facilities for wind power generating plants * Sale Tax Concessional benefits * Electricity Tax exemption * Capital Subsidy 8) KEY FACTORS AFFECTING WIND POWER GENERATION IN INDIA: a) GROWTH RATE OF THE ECONOMY : Market growth rates in these scenarios are based on a mixture of historical figures and information obtained from analyses of the wind turbine market. The annual growth rate envisaged is of 25% per annum, but the wind industry has experienced much higher growth rates in recent years. The growth rate in the last 5 years averaged was more than 35% of installed wind power capacity. The above growth rate assumes significant repowering (replacing of smaller old turbines by modern and more powerful machines) will take place in the period up to 2030. It is also expected that due to the large coastline of 7000km, offshore installations will play an important role in the timeframe. This will substantially increase the overall wind energy potential. b) TURBINE CAPACITY: Individual turbines have been steadily growing it terms of the maximum electricity output they achieve when operating at full power. The average capacity of wind turbines installed in India as off 2008 was 1MW, up from just 400kW in 2000. The largest turbines now available commercially are approximately 6MW in capacity. An assumption can be made that, the average size will increase to 1. 5MW in 2013 to 2MW by 2030. It is possible that the figure will turn out to be greater in practice, requiring fewer turbines to achieve the same installed capacity. It is also assumed that each turbine’s operational lifetime will be of 20 years, after which it will need to be replaced. c) CAPACITY FACTOR: Capacity factor’ refers to the percentage capacity that a turbine installed in a particular location will deliver over the course of a year. This is primarily an assessment of the wind resource at a given site, but capacity factors are also affected by the efficiency of the turbine and its suitability for the particular location. For example a 1MW turbine operating at a 25% capacity factor will deliver 2190 MWh of e lectricity in one year. It is assumed that improvements in both wind turbine technology and the sitting of wind farms will result in a steady increase. ) CAPITAL COSTS: The capital cost for wind energy project shall include wind turbine generator including its auxiliaries, land cost, site development charges and other civil works, transportation charges, evacuation cost up to inter-connection point, financing charges and IDC. The normative capital cost of the wind energy projects shall be Rs. 467Lakh/MW for FY 2010-11 and shall be subject to the adjustment over the control period on account of changes in the wholesale price index for steel and electrical machinery as per the indexation mechanism specified in the RE Regulations. The detailed computations of the indexation mechanism and determination of the capital cost for FY 2010-11. The capital cost of producing wind turbines has fallen steadily over the past 20 years as turbine design has been largely concentrated on the three-bladed upwind model with variable speed and pitch blade regulation, manufacturing techniques have been optimized, and mass production and automation have resulted in economies of scale. Darrieus Three Bladed Horizontal Axis H-VAWT 9) CURRENT TECHNOLOGY OPTIONS IN INDIA: The modern machines manufactured in India with foreign collaboration have capacities more than 1 MW and they are highly suited for India. * The technology option in the first phase of kinetic to mechanical energy has been shifting from constant speed rotor to variable speed rotor all over the world. The variable speed rotor is of capable capturing about 15 to 20% more energy from the turbulent wind. * Conversion of mechanical to electrical energy through the generators is also going through several advancements in technology in the recent years. From traditional squirrel cage induction generators which convert AC-AC as the wind varies has been shifting to synchronized AC-DC-AC type of generators for efficient power capture from the wind. * In the aero dynamic controls, the shift is taking place from traditional stall control to pitch control and modern machines have active controls independently for stall as well as pitch mechanism. These sophisticated active controls require power electronics and hydraulics interfacing with various systems. Some of the latest Wind Energy Generators use electro-magnetic/mechanical control systems instead of hydraulics 0) MISCONCEPTIONS REGARDING WIND ENERGY : a) Wind Turbines kill birds and also have serious environmental impacts: It is a fact that a number of birds have been killed by wind mills. A detailed study done in the United States has indicated that the number of birds currently kill per year due to high end wind installations is one to two birds. Comparatively, more birds die every year because of highway traffic, manmade structures and housecats. These wind turbines also do not affect the migratory patterns of birds and as studies have indicated, the birds that have been occasionally killed are of common species. ) Installation of wind turbines produces a humming noise that is harmful to human health: In continuation to the point above, studies done by research teams in the United Kingdom have proven that the low humming noise produced by the rotating of wind mills has absolutely no effect on human health. With the improvement in technology, this humming noise has considerably reduced over the last few years, by around 30% in terms of decibel levels over the last four years. c) Wind Turbine Farms have a large land foot print: This is a common misconception that people hold in their mind. The actual land foot print of each wind turbine is just the area covered by the wind turbine column that is the foundation of the wind turbine in the ground. The area around the wind turbine can be used for agriculture cultivation or other purposes. In India a number of wind turbines are placed on hilly areas and hence do not take up valuable agricultural land. 11) WIND MANUFACTURERS IN INDIA : There are more than 12 manufacturers of Large Wind Turbines/Large Wind Generators which are grid connected to State Electricity Boards. Most of the manufacturer’s facilities are located in Pune, Ahmedabad, Chennai and Puducherry. As the technology has been steadily improving, it has resulted in the cost reduction of more than 8 times in the last 3 decades. This has increased the number of new entrants in the wind energy sector. From Table 3 given below you can see some of the names of the manufacturers along with the foreign collaboration: TABLE 3 – Large wind generator manufacturers in India From the above list, Suzlon Energy Ltd. is the largest manufacturer in India; It is the world’s 3rd leading player in wind energy generators. Apart from meeting the India wind energy generator market, for several manufacturers it is also an export opportunity – around Rs. 8000 crores worth of equipment was exported abroad. Suzlon has supplied over 7,000 MW of wind power generating capacity equipment in India. In 2006, it acquired Hansen Transmissions NV , the world’s second largest wind gearbox manufacturers, completing its quest to integrate all critical components into its value chain. In terms of net worth, Suzlon is the most valuable wind power company but not as measured by market value. Suzlon currently operates the largest wind park in the world, the 584 MW wind park in the Western Ghats in Tamil Nadu. For small wind generation manufacturers in India ( Small wind generation systems with generation capacity upto 50kW) the major players in the Indian industry are : * Unitron Energy, Pune * Vaigunth Ener Tek Ltd, Chennai * LeanWay Energy Pvt. Ltd, Pune * Tachometric Controls, Pune * Wind Turbine Systems Ltd, Bangalore * M/S Machinocraft, Pune * Novergy Energy Solutions Pvt. Ltd. , Udaipur * Pawanmitra Aero Energies, Tiruppur * Pioneer Wincon Pvt. Ltd Small wind generation systems have tremendous potential in India as a large percentage of the population is still not connected to the grid and hence depends on diesel generators in many areas for intermittent power supply. The small wind generators have the capabilities to replace the diesel generators entirely and with the help of battery storage that can be used for small wind and solar hybrids, areas currently off the grid can be powered, thereby replacing the need for a connection to a power grid. In the last six months, big players like Tata Power Company from the house of Tata ave started experimenting with wind mills of 2 kW capacity and they to plan to enter the small wind generation industry over the coming year. 12) ROLE OF C-WET IN THE INDIAN WIND INDUSTRY : C-WET is an acronym for Center for Wind Energy Technology. As earlier mentioned, C-WET is an Autonomous Ramp;D Organization, established under the Ministry of New and Renewable Energy and it has enabled orderly wind p ower development in India. It offers value added services in terms of identification of potential windy sites and project planning, Micrositing and due diligence studies in the area of wind resource assessment.. C-WET has an International standard Test Station at Kayathar close to Kanyakumari which can test wind turbines from 225 kW to 1 MW class machines. C-WET also ensures the quality of the machines which are connected to Indian power utilities to protect the investors as well as manufacturers utilities equally. C-WET follows IEC:WT-01 standards and carries out the type certification of wind turbines under a scheme called TAPS 2000 which has been customized for Indian conditions with the help and guidance of experts from RISO/Denmark which follows several standards which are currently in vogue in the Indian Wind Industry. C-WET coordinates with several academic institutions, National Research Laboratories and private companies independently in Research and Development in the area of wind energy to facilitate cost reduction in wind electric generation. C-WET assists the regulatory body which is the Central Electricity Regulatory Authority (CERC) in technical matters on policy and regulatory issues. It does the design evaluation for the purpose of certification of assessing the various models which are being offered by several manufacturers in Indian market following International standards. C-WET also undertakes Human Resource development suitable to the Indian Wind Energy Industry by conducting National and International Training Programmes. Since this is an area of multi disciplinary nature, academicians amp; industry and Scientists of C-WET join hand together to complete the training programmes. 13) THE FUTURE INDIAN WIND ENERGY SCENARIO : The main issue of Wind Power Development in India is availability of accurate wind potential data for regions all over the country. C-WET has assessed ore than 620 Stations spread all over the Country by continuous monitoring of wind as a resource and identified more than 216 locations as economically viable and wind potential. As on date, in India a site which has more than 200 watts per square meter as Wind Power Density (WPD) is declared economically viable. With recently picked up micro wind generation i. e to exploit urban wind areas and low wind areas and to facilitate remote village electrification domestic wind mills of . 3 kW to 30 kW are being adopted. This micro wind generation as on date has a low market demand since it has been mostly developed as a standalone system which is often not grid connected. The grid interface system which will have similar concepts such as net metering along with exporting to grid and importing from the grid in a house connection is likely to be possible soon. It has fast track implementation of wind power projects given by Government having fiscal and financial initiative. India is likely to penetrate the wind as a green power up to 10% of electricity generation of the Nation, with the highly supportive Governmental policies. The major issue of utilization of wind power has been the infirmity of the wind. This can be overcome the current sophisticated technology to forecast wind enabling load scheduling to meet the load demand and generation gap. Innovative approach to Operation and Maintenance â€Å"Oamp;M†, is now being implemented using Central Monitoring systems and SCADA type continuous monitoring with remote controls. Another important issue in the Indian wind power development is development of infrastructure facility in wind farmable areas such as roads and logistics for larger machine components to reach windy Regions. Other infrastructural facilities for establishment of human habitation wind farm and establishment of electrical grid for evacuation of the power generated by the wind turbines. Most of the State and Central Government have been concentrating on these infrastructural developments and hence wind power in India has become more viable and the growth is sustained at the global rate of more than 20% every year. Table 4 gives a few keys for sustaining this 20% wind power growth envisaged in India TABLE 4 Wind Power Industry Trends Other Important Areas for the Future of Wind Generation in India : * In the coming years we need proper tariff and inflation adjustments for the wind energy sector. * Preferential tariff has proven to be the most successful instrument in accelerating power generation from renewable energy and should be applied to wind energy generation. * Renewable Energy Certificates (RECs) need to be made available more easily and should be traded so that Renewable Purchase Obligations can be fulfilled in states where sufficient renewable energy is not available within the state. These certificates also need to be electronic in nature to ensure timeliness in transactions and terminate the need for physical documents to be exchanged. 14) CONCLUSION: The wind energy sector has grown significantly in India despite ups and downs. Today after having surmounted many a problems, wind in India is known to be a very mature industry. Presently, the focus is on higher capacity machines and low-wind regime turbines, which operate in class two wind regimes. Higher tower heights and wider swept areas have resulted from the experience gained by India in the last two decades. Equally important has been the ability of wind power producers in dealing with grid problems in the country. Electricity produced from renewable energy resources like wind requires two kinds of support, namely a price support mechanism that enables power producers to enter the market and make a reasonable profit and a stable regulatory environment that encourages renewables based power. Characterized by the non-internalization of external costs of energy production, costs of wind power tend to be significantly higher than that of conventional power. But the cost of delivered power should be measured in terms of overall benefits associated with that form of power, and their implications. In such a scenario, wind power outweighs the conventional power on account of their environment-friendliness and positive impact on the social development.

Should there be laws limiting the paparazzi Research Paper

Should there be laws limiting the paparazzi - Research Paper Example These laws are often meant to be punitive in nature, and this is because it is believed that the paparazzi have taken matter to extremes through their ensuring that they get shots of celebrities living their lines. One thing which is not often considered by lawmakers when making anti-paparazzi laws is the fact that most of these individuals only get involved in such behaviour because of the popular demand from the public, to see the private lives of their favourite celebrities. It has been stated that the paparazzi has to be contained because of the belief that they adversely affect the lives of celebrities and their families, who would otherwise prefer to live private lives. The fact that quite a number of celebrities have ended up having accidents or even losing their lives as they attempted to escape the paparazzi are among the reasons why laws to curb paparazzi activities have been instituted. Most countries in the developed world are taking what is considered to be the paparazzi menace seriously, and they have come to put laws in place which have the intention of ensuring that celebrities and other important people are kept safe from the paparazzi (Neeley 36). The justification for such arguments have been found wanting and this is because many of the celebrities who the laws are meant to protect, while they deserve their privacy, also need to understand that they cannot avoid the consequences of their fame. The paparazzi have been blamed for the death of Princess Diana, who, it is claimed, was attempting to escape them when the accident that killed her took place (Hindman 666). The strength of such arguments has been based on what can only be considered to be falsehood because while the paparazzi might have been following Princess Diana, it was not they who caused her accident. On the contrary, it was her decision to run away from them which led to the accident that took her life. Thus, the laws limiting the paparazzi based on this argument can, therefore , be said to be unconvincing and an injustice on the paparazzi since they have a right to do their work under the protection of media freedom. One of the advantages of laws limiting the paparazzi that have been propagated is that they are meant to protect celebrities from the irresponsible behaviour of the paparazzi (Moreham 606). This has created a situation where almost all the actions carried out by the paparazzi has been found to be irresponsible, and this is despite the fact that it is the best way through which they can do their work. As a consequence, in many countries in the western world, the ability of the paparazzi to competently do their work and satisfy the demand for the photographs of individual’s celebrities from all over the world has been curtailed. Instead, the large scale attempt to muzzle the paparazzi has resulted in the destruction of media freedoms as guaranteed by the laws of almost all the states in the developed world (Komperda 25). It can be said t hat the passing of laws intended to curb the activities of the paparazzi is the first step in a process which is meant to limit the freedoms of media all over the world. It is a process which, despite the good intentions to protect the private lives of celebrities by lawmakers, might have a disastrous effect not only on the paparazzi, but also individuals all

Consumerism in Contemporary America Essay Example | Topics and Well Written Essays - 1000 words - 2

Consumerism in Contemporary America - Essay Example The paper entails a personal perspective in regards to the lessons learned from â€Å"The Year Without Toilet Paper† and â€Å"Thoreau’s Worst Nightmare† articles. The â€Å"Year Without Toilet† Paper falls within the article of â€Å"No Impact Man†, which is about Beavan, a man desiring to conserve the environment by neglecting commodities produced through modern technology. Beavan decides to live on earth and ensures there is a use of affirmative commodities for the safety of nature. The â€Å"Thoreau’s Worst Nightmare† describes how different the early life of Walden is compared to the life of his children. Consumerism refers to a situation where states desire to safeguard the interest of consumers pertaining to the products they (consumers) access, commodity pricing, and content of adverts. Consumerism in America entails an interest in improving consumption of manufactured products. Cornyn states that changes in American’s economic status led to a concern in the economic sector. Poor quality production in the manufacturing industries contributes to changes in customer preferences and hence decreases in the product demand. Services offered to customers determine the desire to go for other products of lesser costs to satisfy individual’s taste. Low incomes in the market industry disabling the processing departments result from a decrease in the selling of products. The belief that security required during business transactions is by government officers, company accountants, and organization inspectors seized to be truly certain grounds. The reason for the belief being false is because of increase in knowledge of people owning business entities. People with diversity in professional knowledge operate in different departments to guarantee growth of organizations under less expense.

Cultural Diversity in Business Essay Example | Topics and Well Written Essays - 1250 words

Cultural Diversity in Business - Essay Example In Brazil, the level of power distance is extremely high as compared to Denmark. This means, all the individual within the society of Brazil is not equal. Due to which, the less powerful members of the society or organization had to obey the rules and regulations of the powerful persons. As a result of which, the manufacturing unit of Brazil may face the problem of interpersonal conflicts among its members. This is because; all the members of the organization may not follow the orders or policies of the more powerful individual and it might lead to clashes or quarrel. Due to which, the rate of retention of the employees might get reduced resulting in attrition or lockouts. This might not only hinder the image of the organizational unit but also hamper its prosperity in long run. Other than power distance, the masculinity is also quite high as compared to Denmark. As a result of which the female members of the organizational unit of Brazil may not be offered equal rights and privilege s and that may create conflicts among other members. Due to which, their level of motivation and commitment of the female employees might get reduced that may hinder their productivity and performance. However, due to lack of performance of the female employees, the overall profitability of the organization reduces to a significant extent among many other rival players. Due to lack of equal rights, the interpersonal relationships among its members might get reduced that may hamper their performance and commitment level.

Three-Dimensional Grade Control in Road Construction

Three-Dimensional Grade Control in Road Construction Three-Dimensional Grade Control in Road Construction using Unmanned Aerial Vehicle Introduction Contractors have used grade stakes installed on the side of the road at intervals of 100 feet for the vertical grade of the finished ground surface in road construction. The grade stakes are measured based on control points(CPs) which are reference points and markers established by surveyors at the design phase. By using the grade stakes, the contractors align the grade elevation with regulated tolerances which are typically less than 0.05 feet for subgrade and 0.02 feet for roadway surface (Missouri Highways and Transportation Commission 2016). The contractors confirm the final construction layout including as-built cross sections, which are measured by a total station or conventional survey methods such as a level, theodolite, and transit at intervals of 500 feet. The final products should be in reasonably close conformity with the design plans and specifications (Floyd et al. 2013). Figure 1: The conventional grade control using grade stakes (Missouri Highways and Transportation Commission 2016) However, in many cases, the contractors have experienced unsuspected discrepancies between the as-designed model and the as-built model, which cause the project cost and time overrun (Pitman 2001). These discordances could be derived from technical issues or human matters that are issues among people such as a lack of coordination and communication between designers and contractors (Arain et al. 2004). While the problems caused by human issues could be solved easily by involving the contractors and designers as coordinators, the resolving the technical problems, such as a measurement error, still remain challenges because the conventional grade control methods use only a few points to build a final grade layout, which can cause considerable errors at the non-measured area. For this reason, many researchers have studied on the application of new technologies such as a global positioning system (GPS), robotic total station (RTS), and terrestrial laser scanning (TLS) to obtain dense poi nts for the grade control. Despite all these efforts, the contractors are still using the traditional methods for grade control because of the disadvantages of the new approaches regarding the economic and usability. In this regard, unmanned aerial vehicle (UAV) is the most reasonable way to overcome such shortcomings (Nex and Remondino 2014). The photogrammetry using UAV is a time-competitive method to generate a digital surface model (DSM) which enables contractors to obtain the dense point cloud of the long-strip roadway construction site without intervals (Chiabrando et al. 2009). Moreover, the UAV allows the user to avoid working in hazardous environments (Barry and Coakley 2013). With such advantages, several researchers apply the UAV to roadway construction, especially for surveying earthwork projects (Siebert and Teizer 2014). The current accuracy of the UAV photogrammetry, however, does not completely meet the particular requirements in road construction such as the grading tolerance which is less than 0.05 feet. This study, therefore, reviews the current state of the three-dimensional grade control in road construction and presents a best practice for applying the UAV for the construction by providing a way to develop the accuracy of the UAV photogrammetry. Moreover, this study verifies the improved accuracy through the field test at an ongoing highway construction site in Georgia, the United States. Literature Review This study has reviewed current studies on the 1) grade control methods in road construction using dense point clouds, 2) applications of UAV for highway construction, and 3) accuracy of UAV photogrammetry. Current study on the grade control in roadway construction As mentioned above, the contractors today perform the grade control in a conventional manner using grade stakes and cross sections because those methods dont require a specialty. However, such methods are conducted sparsely at regular but widely spaced intervals, which can give rise to substantial errors when the contractors build a successive three-dimensional as-built model. To avoid this, many researchers have studied on the way to create a 3D as-built model without intervals as below. 3D grade control using GPS installed on the construction equipment The real-time kinematic (RTK) GPS technology provides a location information for a dynamic motion in real time. The advent of the RTK-GPS technology enables the users to control the machines blade systemically and to build 3D as-built model automatically (Stewart, 2006). For this reason, many global GPS manufacturers, such as Topcon, Trimble, and Leica, present automatic 3D grade control technologies as seen in Figure 2. According to a final report on Implementation of GPS Controlled Highway Construction Equipment in the University of Wisconsin, the use of the GPS to guide construction equipment is time-efficient and cuts costs (Vonderohe 2007). Figure 2: GPS controlled roadway construction equipment Accordingly, many Department of Transportation (DOT) have increased the implementation of the automated machine guidance with GPS (Townes 2013). However, the vertical error of RTK-GPS is typically over 1.5 inches, and sometimes a sudden elevation shift caused by a cycle slip or multipath, which can lead to a significant discrepancy between as-design model and as-built model. Therefore, its impossible to fully adopt the GPS to grade control in roadway construction unless there is an enhancement of the accuracy. Terrestrial laser scanning (TLS) for the highway construction process monitoring The TLS, which measures the location of thousands of points each epoch at ranges of hundreds of meters, is another method to collect high dense point data. The TLS generates more accurate 3D layouts than conventional survey methods (Slattery and Slattery 2013). D. Slattery et al. (2010) demonstrate that the TLS is a feasible means to control the grade in highway construction projects and to calculate earthwork quantities (Slattery and Slattery 2010). Despite the fact that the TLS guarantees accurate point clouds, this new technology faces several operational challenges. One of the primary challenges is that it takes extremely long time to acquire the dense points. In general, the measurement using TLS takes one hour to measure the area of 20,000 square feet. Furthermore, as the scanner is installed on the ground, TLS method forms shadow zones where cannot scan due to obstacles such as trees and hills. In particular, since the roadway construction site is quite long, such drawbacks co uld be fatal. In this regard, the UAV, which is a less time-consuming way of measuring fields, could be an effective alternative. Application of UAV for roadway construction The UAV referred to as a drone, has recently begun to be applied to the construction field with the improvement of the positioning technologies and high-performance digital camera (Turner et al. 2012). With the development of the high-performance UAV, many researchers have successfully applied the UAV for the 3D modeling of the construction site and the measurement of earthwork quantities. S. Siebert and J. Teizer (2014) presents a practice for the application of UAV to construction survey for earthmoving of the construction site. They assert that the UAV technology is a cost- and time-effective alternatives to ground-based survey applications (Siebert and Teizer 2014). Furthermore, M. Daakir et al. (2015) describe that the UAV equipped with GPS receiver can achieve a consistent 3D model with a relatively low cost (Daakir et al. 2015). The studies on the application of the UAV has been limited to the particular construction fields such as earthmoving project and field survey for plan ning the road construction because the accuracy of the photogrammetry using UAV is over two inches which exceed the tolerance for the vertical grade. Thus, the improvement of the accuracy of UAV photogrammetry is required prior to applying the UAV technology to the grade control in roadway construction. Figure 3: The developed UAV systems, S. Siebert and J. Teizer (left), M. Daakir et al. (right) Accuracy of UAV photogrammetry Several researchers have examined innovative ways of improving the accuracy of the UAV photogrammetry. The accuracy of the UAV photogrammetry directly depends on the ground sampling distance (GSD), which is determined by the focal length, flight altitude, and resolution of the camera. In general, higher GSD value indicates that the image would have a lower spatial resolution. Therefore, the altitude of the flight should be performed around 150 m above ground level to obtain images at the GSD of up to 10 cm. (RuzgienÄ- et al. 2015). In addition, the use of geo-referencing methods aligning UAV imagery with known points measured in advance also can improve the accuracy of the photogrammetry. J. Goncalves and R. Henriques (2015) assert that the vertical root mean square (RMS) errors of UAV photogrammetry can be decreased to 5cm by using ground control points (GCPs) as the geo-referencing (Gonà §alves and Henriques 2015). However, a minimum of three GCPs are required for the geo-refe rencing, and generally, more than nine GCPs should be appeared on the imagery to retain redundancy for least squares regression. Moreover, the method that aligns the imagery known as Image registration causes a systematic error which is a cumulative error. In particular, since the road construction site requires extremely long longitudinal measurement, the registration error is theoretically increased in direct proportion to the length of the construction site (Zheng et al. 2016). This study, therefore, proposed a method to correct the systemic error by originating the position of the flying UAV with dual-frequency RTK-GPS and resection method. Figure 4: The GCPs that J. Goncalves and R. Henriques (2015) used Methodology This chapter enumerates the methodology for applying the UAV photogrammetry to the grade control in road construction as follows. Type of UAVs Ground Sampling Distance (GSD) Ground Control Points (GCPs) Positioning of the UAV using space resection method 3D model generation Verification Types of UAV The type of UAVs is classified into three categories: fixed wing type, rotary wing type, and hybrid wing type integrated the fixed wing and rotary type. Fixed wing UAVs have characteristics that they have a simple mechanism and more efficient aerodynamics which allows the fixed wing UAV to fly longer duration at higher speeds than the rotary wing. On the contrary, the rotary wing UAVs have a relatively more complicated structure which may infer that they have lower speed and shorter flight range than fixed wing. The advantages of the rotary wing are that they can conduct vertical takeoff and landing (VTOL) and hovering. The fixed/rotary hybrid UAV has both characteristics of the fixed wing type and rotary wing type. The hybrid UAVs can perform VTOL and hovering and fly with little power like the fixed wing UAV. Table 1 shows the differences between the fixed wing and rotary drones. Since the roadway construction site is quite long and doesnt have vertical obstacles, the fixed wing ty pe of UAV is most appropriate for the surveying the road construction area. Most UAV for the land survey is equipped with single frequency GPS receiver for positioning of the flying vehicle. In general, the vertical accuracy of the single frequency GPS is compromised. For this reason, this study suggests mounting a dual frequency GPS on the UAV to improve their positioning accuracy. The vertical accuracy of the dual frequency RTK-GPS is known to be lower than 2cm in general circumstances. This study might use virtual reference station (VRS), which facilitate the RTK/GPS based on National Continuously Operating Reference Station (CORS). Table 1 The differences between fixed wing type and rotary type Fixed wing Rotary wing Purpose Mapping Small area Mapping Inspection Application Land surveying (rural) GIS Construction Inspection Real estate Surveying (urban) Flight Speed High Low Coverage Large Small Flight Duration Times Long Short Wind Resistance High Low VTOL X O Hovering X O Ground Sampling Distance (GSD) As mentioned above, GSD value is related to the flight level, focal length, and resolution of the camera. Since the GSD value directly affects the results of the photogrammetry, it is important to determine the flight altitude. For a given flying height H, the GSD will be given by Where f is the lens focal length, and H is the flight altitude. Typically, in the case of the GSD of 5 cm, the standard deviation of 1 pixel in the parallax may result in a standard deviation of approximately 5 ~ 10 cm in the elevation error. The flight altitude also affects the overlapping rate which is related to the accuracy of the photogrammetry. That is to say, for a given focal length and resolution of the camera, increasing the altitude will increase overlap rate and GSD. Since it is possible to fly the UAV at low altitude in roadway construction site where is a barrier-free area, this study limits the flight height to 100 m or less to maintain the GSD of under 5cm. Although flying at low altitude can cause little overlap rate, the matter of overlapping can be solved by taking more pictures. Ground Control Points (GCPs) In the photogrammetry for field surveying, establishing a network of the ground control points The GCPs installed on the field is employed for the geo-referencing. Although the bundle image adjustment needs to have at least three GCPs, it is necessary to have 9 or more GCPs for providing enough redundancies for the least square adjustment. The GCP photogrammetric targets should be visible in the pictures and have about 5 ~ 10 times the dimensions of the GSD. Since the accuracy of the GCPs is crucial for the accuracy of the final results, the position of the GCPs should be measured precisely by total station or post-processing GPS. M.Chahbazi et al. (2015) state that although a large number of well-distributed GCPs as seen in Figure 5 (left) guarantees the highest accuracy, if it is impossible due to the field conditions, the best practice is to install the GCPs near the ends of the flight strips to be visible in several images from two closest strips. Furthermore, placing the GCPs with height variation is beneficial for the vertical adjustment of the UAV imagery. Figure 5: The methods to set up the GCPs in the article of M.Chahbazi et al. (2015) (left) when there are enough GCPs, and (right) if not. According to the construction survey manual of U.S. Department of Transportation (DOT), contractors or sub-contractors should establish control points (CPs), which are semi-permanent reference points built beside the construction site at intervals of 500 feet, to align the horizontal distribution and vertical elevation. Since these CPs are measured from the second-order benchmark, which has a ratio of closure of 1:10000, it is possible to construct accurate GCPs. Positioning of the UAV using space resection method The position of flying UAV has been determined from the GPS embedded on the UAV until now. However, the accuracy of the GPS depends on the satellite signal which sometimes includes serious errors such as cycle slip or multipath caused by the environmental conditions. Moreover, time synchronization between the GPS and images from the Camera can also cause several errors. In this regard, this study proposes a new positioning method that improves the accuracy of the photogrammetric results by applying space resection method. The resection method is to determine an unknown point from two known points. This measurement method is usually used when measuring the location of the device such as total station or theodolite. Figure 7: The concept of the space resection for UAV photogrammetry (Ref. https://dronemapper.com/uas_photo-grammetry_processing) The space resection requires at least two known ground control points per an image, but this study used five ground control points for the least square adjustment. The accuracy of the space resection only depends on the range error of the camera, which is much more accurate than RTK-GPS, and therefore this study expects an improvement in the positioning accuracy of the operating UAV As-built 3D model generation The stereo images extracted from UAV photogrammetry go through the image matching process. The image matching process is usually classified into correlation based method and feature-based method. The correlation based method has various computational processes because they conduct the image matching with all area and pixels. In contrast, since the feature based method adjusts images with edges or corners in the pictures, the processing is faster than the correlation based method. Scale-invariant feature transform (SIFT) is one of the most widely used features detecting method. The SIFT algorithm extracts key points from overlapped area, and align the images by using descriptors which are created from the extracted key points. The 3D structure is built by structure from motion (SfM) algorithm, which is a method to generate 3D structure by calculating the pose of the camera from 2D images. Most commercial software today has used the feature-based image matching and SfM algorithm to cre ate a 3D model. One of the commercial software is Agisoft PhotoScan which conduct image matching with the feature-based method. This study generates the as-built model of the roadway construction site based on the DSM generated from the Agisoft PhotoScan. The final as-built 3D model would be compared to the as-design model. An essential issue in this step is to synchronize the coordinates system used in both as-design model and as-built model. For this reason, it is essential that both models should be on the geographic information system (GIS) based on a global coordinate system.

Television Crime Series :: Research Paper Crime Series Essays

Television Crime Series Television crime series are inherently religious. They present disturbing questions of death, guilt, justice, mercy, confession and absolution, and hope or hopelessness. One episode may be viewed as a parable, with the center as the courtroom scene with its "moment of truth" when the norm inverts and strangeness enters, as in a parable. They are parables, for parables are the Kingdom of God and the Kingdom of God is here and now as Jesus said, Mk1:14-15. It breaks into our world and inhabits it while remaining holy. A parable is the language of Jesus, himself a parable of God. A parable is often introduced by, "The kingdom of God is like . . ." It is without much specific detail and it has a single point of view. Many parables are open-ended and rather mysterious even as they remain attached to nature or the simple life. They are lively and arresting and easy to remember as lessons and they are puzzling. A short description of the Parable of the Mustard Seed will suffice now; later it will be compared to the crime episode. Briefly, the smallest of seeds, the Mustard, is planted and produces a great shrub or tree where birds can nest. It is labeled a parable of growth but it could also be called a parable of reversal i.e. from small to large, from a dried-up seed of stored life to fecundity. The crime series receives equally brief treatment until the pivotal courtroom courtroom scene. The characters are two detectives, four attorneys, a grieving mother and her two children, an infant and a boy, both shot: the infant dead, the boy maimed; a wealthy African-American drug dealer and his "errand" boy of thirteen years who did the shootings for his employer and is now on the stand watched over by the evil dealer who lounges impassively in his cashmere coat. We have come to the courtroom scene in which justice will out, Mark 1:14-15 The time is fulfilled and the Kingdom of God is near; repent. . . All characters are present and the only action is the expressions which cross their faces. The boy’s face shines under his knit cap; he appears innocent, amoral at most. He does not seem to understand the proceedings. He said he had received written instructions and an address to "clean the residence" of a customer behind on his payments. The District Attorney wants to indict the dealer and he introduces, not new evidence, but two different typed sheets which he hands to the boy to read.

How valid is the view that, “in the period 1796-1870 the most serious barrier to political change in Italy was widespread apathy among the people?

In 1871 Italy became a unified nation, however in the period of 1796-1870 there were many barriers, which prevented the political change in Italy. The widespread apathy of the people certainly did effect the unification of Italy, however there were other barriers such as the foreign influences of Austria, the un-organisation of the revolts and the fact that at the beginning the Risorgimento was more for the elitist class. So it is not valid to say that apathy was the most serious barrier as there were other factors that together made it difficult for Italy to become united. One factor that was particularly influential was the power Austria has over Italy. Austria was a major power at this time with a large empire. During this period there were a number of revolutions across Europe. Austria and Russia were both conservative monarchists that were determined to suppress any nationalistic movements as possible as they were worried about the spread of revolutions affecting their own countries. Austria spread its influence in Italy by installing members of the Austrian imperial family, the Hasbburgs, to rule in many Italian states. This was used for a more pro-Austrian attitude and a less patriotic nationalistic attitude to their own country; Italy of 1815 was basically under control of the Austrians. Metternich said at the time; â€Å"Italy is only a geographical expression.† It is clear that Austria were a major influence and helped to prevent Italy from developing it's own identity thus preventing unification- which was Austria's main aim. It is true to say that Austria exerting it's power over Italy does show the apathy of the people as they didn't seem to do very much about it, or appear to concerned for some time. Less than 3% of Italians spoke Italian, and as communication wasn't very good it was hard for Italy to feel like one unified country as they were so separated. People's sense of pride was what was missing in Italy. People were very attached to their own particular region and in a sense were not affected by what happened in other areas of Italy, especially the north-south divide. It could be argued that this un-communication between different areas of Italy proves that apathy among the people did prevent unification, as the Italians were obviously not prepared for it. However if the government gave the public a reason to be proud and patriotic, and given them a sense of unity they probably would have reacted and been more unified. In fact not all Italians did have this apathetic attitude towards unification. There were attempts of revolutions in 1820 and 1831, but the force of the Austrians easily crushed these attempts. The Carbonari (1820s) were a secret society attempting change but didn't work as there were too few of them. There are also examples in radical democrats such as Garibaldi and Mazzini that played a big part in the unification process as they really believed in it and managed to spread the message more too the masses. This was another barrier to political change that there was little support for the attempts at revolution. This was to do with the fact that the Italian people has been led to believe that democracy was a thing to be feared, and unification may make Italy worse. Also during the beginning the Risorgimento was more of an elitist phenomenon, where only people of education and urban centres could get to hear about it. There was also a lack of co-ordination and confusion between the different ideologies that proved to make revolutions difficult. The Italian public were also unsure of what type of Italy would result after a revolution has taken place. There was particularism between some Italians and their own states as they may have felt they were better off not unified as it may change things in a way they didn't like. Before the Crimean war (1854-56) there seemed to be little chance of Italian unification as the country was so divided and controlled so greatly by Austria. The Crimean war changed a lot of things in Europe. The war was the resultant reason for the two major powers of Austria and Russia to break their alliance. Russia was humiliated in the war and was un-supported by Austria. Russia felt like it had been denied to be seen as the major power that it was. Russia therefore was un-supportive of Austria and changed it's policy, having been before quite conservative, to an attitude favourable of change. With the weakened force of Austria and its plight to prevent democratic states, people like Garibaldi creating a new found patriotic atmosphere among Italians, by 1871 Italy was unified. Overall it is valid to say that the apathy of the Italian people was a barrier to political change. In some ways the apathy of the people was not just because they weren't bothered but because the majority did not receive information about the Risorgimento till quite late. However it is more the foreign opposition of Austria that was more of a powerful prevention to change that affected the unification process more than the apathy of the people. It was partly due to the â€Å"domino effect† the Austrian influence had that did help to encourage the apathy of the people, as Austrians were so desperate to reduce nationalism they managed to help prevent Italians from feeling a belonging to a country.

First Amendment and Music Censorship

First Amendment and Music Censorship The First Amendment to the Bill of Rights exists because the Founders of our country understood the importance of free expression. The First Amendment states "Congress shall make no law . . . abridging the freedom of speech, or of the press . . ." (Commission on the Bicentennial of the United States Constitution 17). One of the ways the American people use this freedom of speech and expression is through the creation of the art form known as music. Music's verbal expression bonds our society through our emotions and experiences. This fundamental right of freedom of expression is being threatened by public and governmental groups who believe they have authority to monitor and decide what others should experience. The censorship of music lyrics is a violation of our First Amendment right, and public groups should not be allowed to bypass this right to censor obscene lyrics produced in the music industry.English: The Bill of Rights, the first ten amendme...Through the decades, artists s uch as Elvis Presley, The Beatles, and The Rolling Stones have raised controversy over their seemingly explicit acts that are now viewed as legendary. Parents banned their children from watching Elvis Presley and his outrageous hip movements though today these moves are copied by Britney Spears, pop groups, and dancers all over the world. In 1956, Ed Sullivan deemed Elvis "unfit for a family audience." However, in 1970 Elvis met the President in the Oval Office, and now his face appears on a postage stamp (RIAA; History 2 of 4).

How dose Hitchcock present duality and the complexity of the human nature in the film Psycho Essays

How dose Hitchcock present duality and the complexity of the human nature in the film Psycho Essays How dose Hitchcock present duality and the complexity of the human nature in the film Psycho Paper How dose Hitchcock present duality and the complexity of the human nature in the film Psycho Paper Essay Topic: Film Hitchcock presents duality and the complexity of the human nature by using contrast in the film. The main kinds of contrast shown in the film are black and white, light and shadow, and the fight between good and evil. In the film see that there are two sides to peoples personalitys, hitchhike often shows this by using mirror images. Psycho was made in the 1960s. At this point of time colour was in wide use, however, Hitchcock decided to make the film in black and white, his reasons, the films too scary! However, filming the film in black and white added to the effect of duality, such as light shadow, mirror images and life and death. Hitchcock portrays good and bad in people by using black and white, light and shadow and mirror images. For example, in the first scene Marion is in a hotel with her lover Sam, she is dressed in white this gave us, the audience the impression that Marion was innocent. This is because white is often associated with something clean or pure however, when she turns from good to bad we see her dressed in black. Hitchcock often presents duality by using mirror images, we often see a mirror image of a person when a different made up side to a person is being portrayed, and when a character is trying to cover up their true identity and become someone else. For example, when Marion checks in at the Battes Motel, she gives a false name and address at the reception, next to the desk is a mirror image of her-self. This shows the two sides to Marion, good and bad. Through out the film men are portrayed as more menacing than women, they are normally surrounded by sharp objects while women are surrounded by more circular objects. For example, in the pallor scene we see a one 2 one conversation between Norman and Marion. Sharp, pointed objects such as stuffed animals and pictures surround Norman, while oval shapes like an oval mirror surround Marion. Also in this scene Norman is in shade while Marion is brightly lit. These contrasts suggest that Norman is evil and that he has a dark side to him, and Marion is good. One of the main contrasts in this film is Normans split personality: himself and his mother. In the film we learnt that Norman murdered his mother and her lover, because he was jealous. He was jealous of his mothers lover, he felt that his mother was giving all her attention to her lover and not him this growing jealousy lead to the murders of his mother and her lover. This film was all about peoples past lives and secrets hunting them. For example, Marion left her hometown phoenix so she could get away from the crime that she committed. But during her journey a policeman was chasing her. Hitchcock portrays the policeman as menacing, this effect was created by the big black glasss covering the policemans eyes so we couldnt see his facial expressions, he also looked as if he was talking down to her The consequence of the decisions taken by Marion lead to her death. She chose to take the money witch lead her to run away and she chose to check in at the Battes Motel Hitchcock presents the duality and the complexity of the human nature in the film Psycho by using a number of effects such as light and shadow. I think this film was a successful thriller for its time. Hitchcock used an intelligent plot, which inspired a new generation of directors all around the world. Hitchcocks work was often described as the mystery, the madness, the suspense all wrapped up in a neat little box. I think that this is an excellent description of Hitchcocks work because he structured the film Psycho so that we wouldnt know what was going to happen next. He skilfully used music to create suspense, he done this by changing the tempo dramatically

Analysis of Rembrandt van Rijn's Paintings Essay

Analysis of Rembrandt van Rijn's Paintings - Essay Example The essay "Analysis of Rembrandt van Rijn's Paintings" analyzes two paintings, The Descent from the Cross and Philosopher in Meditation, both found in the art museum of The University of Arizona. The Descent from the Cross refers to a scene from the Gospels reports of Joseph and Nicodemus lowering Christ from the cross following his crucifixion. Artists also refer to it as The Deposition of Christ. Other names not stated in the Gospels who were included in illustrations of this art consist of St. John who is pictured supporting a dimming Mary Magdalene. The Gospels reveal an indeterminate number of women as witnessing the crucifixion. It also included the Three Marys: the Virgin Mary, Mary Salome and also Mary Magdalene who witnessed the burial. These and many other women and unidentified male assistant are shown in the painting. Even in early illustrations the facts and pretense of the work of art and the pose of Christ’s body are different. The scene was incorporated in medi eval cycles of Passion or the Life of Christ, from the crucifixion to the burial of Christ. The weeping of Christ and viewing the body of Christ supported by Mary might intervene between those two. This is widespread in the people’s view, mainly in sculpture. The viewing Christ’s body being moved to his tomb, anointing of Christ and showing the body laid flat on the top of the tomb is another picture that might be thought of in the painting. This is vital in the Orthodox art, where it is revealed on the Epitaph. (Rijn 7). With the resurgence, the painting became accepted for altarpieces, partially because of the challenge of the art work and the fitness of its vertical shape. The Mannerist edition of Russo Florentine is viewed as his most significant painting, and Pontormo’s altarpiece is his most determined painting. This topic of crucifixion was painted many times by both Rembrandt and Rubens. Rembrandt also liked the paintings of Rubens (Rijn 7). Rembrandt ad apted the compositional format for The Descent from the Cross from Ruben’s painting. Rembrandt though sets the theme back in time. The posture of the body Christ is also copied directly from Ruben’s work. His description of the limp and the lifeless Christ discloses a sense of brutality and sorrow which is missing in Rubens painting. Rembrandt used himself as a representation for the boy on the ladder who clings to Christ’s arm (Rijn 7). This signified his emotional connection to the painting and his religious passion. This is the only painting by Rembrandt bearing the dedication of an art dealer and modern publisher, Hedrick Van. Rembrandt’s studio at that time was situated in the publisher's house, and it was there that he met Hedrick Van’s cousin Saki. Rembrandt married Saki in 1634. The Descent from the Cross and the Pendant Christ before Pilate were both published by Cum Privileges. They were approved by the States General and are alike to the recent copyrights (Rijn 7).

Economics Essay Example | Topics and Well Written Essays - 500 words - 21

Economics - Essay Example Cones home began to slide, and stated that he would resort to simply killing any of the woodpecker that he saw without informing others, so that he may use his land as he pleases; Cones disregard for the Act made it pointless. To protect endangered species, the government would have to front a massive amount of money if they wish to see success in their plans. The cost of the plan, though, would depend on each endangered species; the species would be funded for individually, not as an entire group of all endangered animals (Keim, 2009). The benefit of the government interfering would be that these species would have a chance to breed and strive, rising above the status of an endangered species. The government would have rules and regulations set down to force people to be aware of their natural surroundings and the environment, in hopes of saving these species. By not protecting an endangered species, the government does not lose money to a cause that may or may not work. Small, individual groups and organizations will have to depend on themselves if they want to see something done. The benefits of the government not helping are that others would not feel forced into helping a cause that they do not care about and that their money is going to something that they themselves can personally benefit from. The downside to the government interfering is that homeowners begin to lose their say in how they keep and tend to their property. These people may not feel the same way about saving a species as someone else might, yet they would be required to adhere to any rules and regulations that are set down for the purpose of protecting these animals. There can also still be instances when the homeowners disregard the regulations, feeling that it is not the governments business to tell them how to tend to their yard, as Cone shows. In fact, as Cone did by threatening to just kill off the woodpecker, people can just cause more harm to the species, even if the government
