Battle Of Chickamauga - Research Paper Example With the help of operation process the commander implemented mission of command. In this battle both the commanders gave direction, support and guidance to the army working under him. As per ADRP 5-0, during this war MG Rosecrans was unable to describe, understand and direct his army properly. The main roles of a commander are to analyze its operations, utilize its resources and communicate effectively with the army for implementing decision properly. MG Rosecrans used cavalry for delivering messages and establishing courier lines which failed miserably. He focused more on La Fayette Road for reaching Chattanooga. But if he had used Dry Valley and Vittetoe roads then he could have gained various opportunities to win the battle. MG Rosecrans was highly involved in managing different small issues of army. He was not concerned about the end result and was generating feasible options. He did not understand the operational environment of the war. Moreover MG Rosecrans failed to deliver his command properly on 20th September which made his army weak in the war. Calvary was used in the war for delivering message and developing courier line. MG Rosecrans used cavalry for managing the army during the war. The misuse of cavalry made the Army of the Cumberland weak. The commander was unable to important information through cavalry. If the commander used cavalry for gathering intelligence then he could have gained strong position in the war. The commander should have focused on exploring various routes for conducting surveillances by using cavalry1. MG Rosecrans relied mainly on couriers for communicating information. He did not used Signal Corps effectively for communicating with its subordinates. There was a need for improved communication in the war. But lack of planning and inefficient use of assets made the communication process weak.

How might an anthropologist analyse a mainstream film Essay

How might an anthropologist analyse a mainstream film - Essay Example The depiction of the characters in the movie is not only racist in more ways than one, it is also extremely sexist. It takes historically inaccurate facts and places the burden of a sexist society upon the tribes of America. The vision that the director and the makers of the movie endorse is extremely problematic and make for disturbing viewing when looked through with a postcolonial and feminist approach. The dissection of the movie in this paper shall then proceed with the gaze of an anthropologist. Another factor that shall be looked into is the fact that Gibson’s movie was a mainstream one and hence factors in popular notions regarding other cultures. This then brings in the elements of reception and the cultural attitudes that are prevalent in the American and also global population. What sections of the population are targeted is also something that needs to be discussed here. This paper shall seek to look at these elements of the debate and also a psychoanalytic approac h into the understanding of why certain races are depicted as they are in popular culture. However, there is another side to this debate. The changes that are introduced into the idea of the Mayans represent the idea of difference between the city and the forest within Mayan culture. The movie is then an indictment of Mayan elite culture that according to Gibson had degenerated into a set of mindless rituals. The city becomes the center of all forms of evil that Gibson associates with Mayan culture. This is then contrasted with the culture that is prevalent within the geographical confines of the village. This village is then the site of family and bonding between different members of the same society. It is a self-sufficient unit that is understood to be a space where traditional aspects of Mayan life are followed without there being a corruption of these ways. There is however, also the presence of technology in the form of traps and other devices that smoothen the life of the peo ple in the villages. There is thus, an endorsement of the idea of the â€Å"noble savage† as Jean Jacques Rousseau thought of it. It discussed the idea of man in a pure state which made him not merely a savage but also a noble one that was purer than the man who had been corrupted by civilization (Basic Concept: Primitivism and the Noble Savage). Throughout the movie, aspects of Mayan culture are denigrated and the only character whose perspective is taken for a large part of the movie is that of the protagonist, Jaguar Paw. The movie traces the life that this character leads where a process of colonization takes place between different tribes within America. The fickleness of power is made clear in this kind of transfer of power takes place very frequently. One of the people who were met by Jaguar Paw is later seen as a captive within a matter of a few days. All of this leads to the series of human sacrifices that take place at the Mayan temple in an effort to appease the Ma yan god Kukulkan. The degeneration of the culture of the elite and those that live in the city are talked of in this movie. The connection between Jaguar Paw and the nature of his homeland is repeatedly stressed. This can also be seen in the way in which the forest decimates the people of the city who seek to kill Jaguar Paw. The connection between Jaguar Paw and his homeland’

Plastics Essay Example for Free

Plastics Essay From the mid-1980s onwards, plastic bags became common for carrying daily groceries from the store to vehicles and homes throughout the developed world. As plastic bags increasingly replaced paper bags, and as other plastic materials and products replaced glass, metal, stone, timber and other materials, a packaging materials war erupted, with plastic shopping bags at the center of highly publicized disputes. Although few peer-reviewed studies or government surveys have provided estimates for global plastic bag use, environmental activists estimate that between 500 billion and 1 trillion plastic bags are used each year worldwide. Plastic has replaced the traditional material (paper/cloth etc) as packing and carry bags because of cost and convenience which is possibly a wrong choice of material for such use. Even though plastic bags can preserve food and can be used for growing vegetables in a controlled environment, their method of disposal has creates unprecedented pollution problem. Plastic has many more uses other than Plastic Bags and Packing material. It is used for manufacturing of protective covers and parts for many machines, which should be the preferred utility for plastic. More than a 100 million tones of plastic is produced world-wide each year. Though plastics have opened the way for a plethora of new inventions and devices it has also ended up clogging the drains and becoming a health hazard. Many countries, including India, are trying to increase the amount of plastic that is recycled. But commercial interests create hindrance for effective legislation to remove plastics from goods where they can threaten public health. Also there is a clear trend of shipping off the plastic waste of developed countries to under develop and developing countries. India imported 7,841. 8 metric tonnes of plastic waste from the US in the first half of 1994. India is the fourth highest Asian importer of plastic waste behind Hong Kong, Philippines,Indonesia. Environmental pollution caused by routinely used polythene packaging materials; it would be prudent, for the present, to use eco-friendly paper packaging. The manufacturers of plastic packaging like soft drink bottles/mineral water bottles etc must come forward and develop appropriate methods of disposal/own responsibility for disposal. Plastic bags were found to constitute a significant portion of the floating marine debris in the waters around southern Chile in a study conducted between 2002 and 2005. If washed out to sea, plastic bags can be carried long distances by ocean currents, and can strangle marine animals or, if ingested, cause them to starve to death. [8] Numerous deaths among animals such as sea turtles and dolphins have been attributed to the ingestion of plastic marine litter, which includes plastic bags. Littering is often a serious problem in developing countries, where trash collection infrastructure is less developed than in wealthier nations. The relatively limited adoption of modern biodegradable plastic bags means that many older landfills are filled with large, persistent deposits of non-degrading bags. It is, however, possible that in the future these deposits could be mined and reprocessed to replace dwindling raw material resources. In recent times due to widespread awareness drive by NGOS and government and to lesser extent by educational institutions has resulted in increasing the consciousness among few shopkeepers they have shifted back to the old system of wrapping up goods in paper bags or newspapers, Some people are slowly getting habituated to going to the market with cloth bags. Besides a few NGOs, even school students have come forward to take up a promotion campaign for the use of paper or cloth bags. Each year, as industry produces more and more nonessential products individually and excessively packaged, we throw away more and more trash. To a large extent, our garbage problem is a result of a corporate ethic that puts profits before people and the environment. Industry is pushing disposability because it pays. Plastic razors can only be used a few times before disposal, then more must be bought, making the plastic and razor industries rich and happy. Appliances designed to become obsolete guarantee youll have to buy new ones next year. Over 84 percent (by weight) of municipal solid waste could be reused, recycled or composted instead of being buried or burned. An exception is plastic, which comprises about 7 percent by weight or 20 percent by volume of municipal solid waste. Due to technical and financial limitations, less than ten percent of plastic is currently recycled. Furthermore, plastic recycling only defers the plastic disposal problem, since most plastic items can only be manufactured from virgin plastic. Recycled polystyrene foam (also known by the brand name Styrofoam) can be used to build marine docks but not to make a new polystyrene foam cup. New plastic will have to be produced from non-renewable oil stocks to make those cups, and eventually all the plastic will have to be disposed of. Last February 21, 2011, the province of Albay, spearheaded by Gov. Joey Sarte Salceda became the first in the Bicol region to ban the use of plastic bags. Provincial Ordinance No. 011 – 3, which is also known as the â€Å"Anti – Plastic† Ordinance of the Province of Albay, prohibits the use of plastic bags on dry goods and regulating the use on wet goods and prohibiting the use of Styrofoam and other synthetic materials harmful to the environment. The ordinance, signed into law by the governor and lauded by the members of the Sangguniang Panlalawigan is expected to eradicate the use of plastics bag by any means. As cited in Section 2 of the ordinance, the law is for the compliance of all business establishments, groceries, department stores, supermarkets, chain retailers and sari-sari stores in the province. Likewise, utilization of alternative packaging materials such as woven native bags (bayong), reusable cloth, shopping bags (katsa), paper bags and other similar materials is encouraged. It is also a known fact that many of those plastic bags that shop owners used to pack their merchandise often ended up in streets. The hazards plastic pose for the province are numerous. Albay being a favorite spot of natural disasters is at risk with the threats of excessive use of plastic products. Also, the province gets littered by plastic bag garbage presenting an ugly and unhygienic seen. The soil fertility deteriorates as plastic bags form part of manure remains on the soil for years. This new ordinance should be taken sincerely because this not only speaks for the lives at stake but for the environment of the next generations as well. Large food chains like McDonald’s, Jollibee and others should start to ban Styrofoam packages among their products. Large supermarkets should take the initiatives and act upon the given law and use alternatives to pack the purchase of their customers. They should also convince customers to bring their own reusable bags when they go shopping. Educational programs anchored to the ordinance should also be created to be able to grasp the students’ awareness about this law. They should be educated as early as in primary years that they may become fully aware of it. Massive campaigns like door-to-door information drive, barangay seminars and other promotions using quad media will be helpful in the realization of the law. Furthermore, environmental awareness of each individual should be encouraged as well.

GSM Communication System

GSM Communication System 1).Introduction: GSM (Global System for mobile communication) is a term known world wide for the digital cellular communication. In 1982 this term was introduced by the CEPT. It created a group, Groupe Special Mobile(GSM), which was provided with the task to design a cellular system that can operate in the 900MHz frequency region. [1] In the early 1980s, most of the telephone systems were analog rather than digital. This had a lot of disadvantages because it was unable to handle the increasing number of customers in a cost effective manner. As a result the digital technology was introduced which would be helpful in increasing the capacity of handling the customers. The GSM network was started in 1992, and in 1993 more than one million subscribers made calls through GSM networks. In the beginning, the GSM network was popular in Europe, but started to spread itself outside Europe. [1] The majority of the GSM networks operate in the 900MHz band, but some operate in 1800MHz band too like (GSM1800) PCN, (DCS1800), and in the United States 1900MHz band (GSM 1900). The basic architecture of these systems is identical but they differ only in the radio frequencies used. [1] There are about 380 million subscribers of the GSM technology in all the three frequency bands(900 MHz, 1800 MHz, 1900 MHz). In total there are 373 networks in 142 countries in operation. The GSM technology has been a revelation as it has made wireless communication easily accessible. 2).The GSM network: The GSM network is divided into three different parts: [2] The switching system(SS) The base station system(BSS) The operation and support system(OSS) 2.1).The switching system: The switching system is responsible for performing call processing and subscriber related functions. [2] 2.2).The base station system: It is responsible for performing all radio related functions. It consist of base station controller(BSC) and base transceiver station(BTS). [2] 2.2.1).BSC: The BSC provides all the control functions and physical links between the MSC and BTS. It is a high-capacity switch that provides functions such as handover, cell configuration data, and control of radio frequency (RF) power levels in base transceiver stations. A number of BSC are served by an MSC. [2] 2.2.2).BTS: The BTS handles the radio interface to the mobile station. The BTS is the radio equipment (transceivers and antennas) needed to service each cell in the network. A group of BTS are controlled by a BSC. [2] 2.3).The operation and support system: The operations and maintenance centre (OMC) is connected to all equipment in the switching system and to the BSC. The implementation of OMC is called the operation and support system (OSS). The OSS is the functional part from which the network operator and controls the system. The purpose of OSS is to offer the customer cost-effective support for centralized, regional, and local operational and maintenance activities that are required for a GSM network. An important function of OSS is to provide a network overview and support the maintenance activities of different operation and maintenance organizations. [2] 3).Multiple accessing techniques: There are different major multiple accessing techniques in GSM, but we will describe just two of them: 3.1). Frequency division multiple access (FDMA): FDMA is one of the most widely used multiple access techniques. In this technique, the frequency band is divided in to channels of equal bandwidth so that the conversation is carried on different frequencies. In FDMA, one specific frequency is allotted to every caller. This cause overload situations in case of high demands. The channel bandwidth is narrow usually 30KHz. [2] FDMA systems include C-Netz. In C-Netz, two frequency bands of 4.44MHz are further divided into 222 individual communication channels at 20 KHz bandwidth. The hardware components in FDMA are simple, but still each channel needs its own transceiving unit. Also, the tolerance required for the high-frequency network and the linearity of the amplifier in the transmitter stage of the base station are high. It is because a large number of channels need to be amplified and transmitted together. [1] 3.1.1). Advantages: [4] No network timing is required. Channel assignment is simple. 3.1.2). Disadvantages: [4] Power levels must be closely checked to obtain efficient use of transponder RF output power. Inter-modulation difficulties require power back-off as the number of RF carrier increase. 3.2). Time division multiple access (TDMA): Time Division Multiple Access or TDMA is a method used to enable multiple stations to transmit on the same frequency but on different time slots. TDMA systems alleviated the channel capacity issue by dividing a single radio channel into timeslots and then allocating a timeslot to a user. TDMA system have three timeslots per channel. To use these timeslots, the analog voice has to be converted to digital. [3] A digital wireless transmission technology, TDMA is used by the digital system Global System for Moblile Communications as a cellular phone technology to fit more cellular users, in sequence, on a single radio without interference from other callers. This form of technology is called multiplexing. A call is placed and sounds are digitized and then the information is broken into data packets which given a unique time assignment. TDMA systems operate in either the 800-MHz or 1900-MHz frequency bands. 3.2.1).Advantages: [4] Shares single carrier frequency with multiple users. Slots can be assigned on demand. Less stringent power control due to reduced inter-user interference. 3.2.2).Disadvantages: [4] Higher synchronization overhead. Equalization necessary for high data rates. Slot allocation complexity. Interference with other devices. 4). Summary: In this report we have tried to cover the basic principles of GSM technology. We explained the basic architecture of GSM along with the multiple accessing techniques involved. We also tried to discuss the advantages and disadvantages of each accessing technique.

Pride And Prejudice Essay -- First Impressions Jane Austen Essays

Pride and Prejudice The novel Pride and Prejudice by Jane Austen was originally titled First Impressions. This is significant because it reflects the values and attitudes of 19th century England, and portrays the main themes of the novel. It is set in England during the 1800’s and Austen focuses on a society whose opinions are based on first impressions. This is achieved through cultural context, characterisation, narratorial commentary, and methods/techniques. During the 19th Century, first impressions were very important. The reader is presented with Meryton, a highly structured class society which judges people on superficial qualities, such as physical appearance, social status, clothes, possessions, behaviour, dialogue. The message Austen positions the reader to understand, is that a society which makes its judgements based on first impressions is immoral and unjust. (-She uses ‘humour’ to help convey this in a less-serious tone.) For example, Mrs Bennett’s first impressions of Mr Bingley were based upon his behaviour and physical appearance. â€Å"Oh! My dear, I am quite delighted with him. He is so excessively handsome!† (Page 16) Mrs Bennett has a driving force in her behaviour to marry her daughters to wealthy men, who were financially stable and socially accepted, so her liking to Mr Bingley is reinforced by his interest in her eldest daughter Jane. â€Å"Mr Bingley thought her quite beautiful, and danced with her twice. Think of that my dear; he actually danced with her twice; and she was the only creature in the room that he asked a second time!† (Page 15) In contrast, Mrs Bennett’s first impression of Mr Darcy was that he is cold, abrupt, and proud. This is established because of his manner and behaviour. The narrator describes Darcy’s behaviour in chapter 1; ‘Mr Darcy danced only once with Mrs Hurst and once with Miss Bingley, declined being introduced to any other lady and spent the rest of the evening walking about the room speaking occasionally to one of his own party. He was the proudest, most disagreeable man in the world, and everybody hoped that he would never come there again. Amongst the most violent against him was Mrs Bennett, whose dislike of his general behaviour, was sharpened into particular resentment, by his having slighted one of her daughters.’ (Page 12) Mr Darcy judges Elizabeth and the Bennett family on soc... ... have prided myself on discernment! –I who have valued myself on my abilities.† (Page) Pride and Prejudice is written in 3rd person omniscient, which allows the reader to delve into the minds of more than one character. The narrator can be persuasive and influential, (this is most common during passages of large summary) although at other times a ‘silent observer’/goes without commentary, (During character dialogue) however the ‘point of view’ becomes more focused through the character of Elizabeth. The narrator has control of selection of detail, and chooses what the reader is entitled to see. (Eg selects the incidents we see, and finds the words to describe them.) The title ‘First Impressions’ is very significant, because the novel revolves around issues which are based on judgemental people, who make and break first impressions. Characterisation and cultural context are used to portray this, and the reader is positioned to understand that relationships based on first impressions have no substance. Both characters develop throughout the novel, and their first impressions of each other gradually change. Darcy’s pride diminishes, as does Elizabeth’s prejudice.

Industrial Music :: essays research papers

Industrial Music Rock and roll is dead. It's a fact. During the eighties romp of techno and fashion bands, people forgot all about it. In the late eighties and early nineties alternative music tried to save rock and roll, but it was too big of a category. If a band didn't sing country or rap, they were considered alternative. Every alternative band had their own idea of music, and it all spread apart, running farther away from rock. Finally, when alternative became more defined and broke off into categories, one specific type of alternative offspring, industrial music, made the best attempt in a decade to revive the long forgotten era of rock and roll. The only problem with this new rock is that it was angered from being forgotten for over a decade and now it's back, filled with angst and hatred. Industrial music has weaved rock and roll with evil and misery. The founder and leader of the industrial revolution is the band Nine Inch Nails. Most people do not classify Nine Inch Nails as a band though. The writer, producer, lead vocalist, keyboarder and guitarist of the band is Trent Reznor. For the past two years, Trent has been the artist of the year in Spin magazine and NIN has been the number two band of the year. In 1994, Nine Inch Nails was announced MTV's band of the year. This was a great honor because MTV spends most of it's time with rap and hip-hop. When NIN's first album came out in 1989, it was mostly rock and roll with a techno twist, containing songs full of depressing, suicidal lyrics. Then as the next two albums arose, Trent became more evil with his music, using machines and pretty much anything he could find that would make his music sound angered and irritated. This hard, twisted music, backed up by words of pure hatred started the industrial ball rolling.   Ã‚  Ã‚  Ã‚  Ã‚  One band that has tried to lighten up industrial just a tad is KMFDM, a German industrial band. The band name stands for Klein Mitlied Fuhr Das Merhiet, which is Little pity for the tyranny. Instead of using the suicidal, evil lyrics, KMFDM has used their music as more of a philosophical communication. They sing about how screwed up they think the world is and how much we are controlled by people we didn't know existed. The lyrics may sound depressing still, but the music is a little more upbeat. KMFDM got rid of the tortured machine sounds and added horns and synthesizers, making the music sound more digital and less like grinding gears.

Christopher Columbus Day Essay

I believe that Christopher Columbus is a villain. I think the anniversary of Columbus be not a time for celebration but for reflection and repentance because he took a whole bunch of Indians captive, hoping they would take him to gold and other treasures. Some other reasons why Columbus Day shouldn’t be celebrated is he kept on collecting gold and Indians to other places he went. Christopher Columbus also opened up the continent to slavery, he was one of the first European slave traders in the world. He had the Indians go to all sorts of places to serve people there. The Spanish came up with an idea with the help of Columbus to make Indians get gold and if they didn’t then they would get their heads chopped off. Ancestors of the European conquest must acknowledge a continuing history of oppression, degradation and genocide because Columbus killed an entire people. Because of what Columbus started the Spanish started to move to African slaves because the Indians were dying too quick. Its not a good idea to celebrate Columbus Day, unless you want to celebrate how he tortured, killed and raped so many Indians and Africans just to get treasure. When other countries realized that there was a new continent they started there own search for gold and other riches. This led to the major countries in Europe colonizing undeveloped countries and establishing colonies. Aboriginals peoples around the world were exploited and used as cheap labour. This is a practice that still continues today. Politically the richer countries set up governments in the poorer countries and began to make the laws and govern these new colonies. Economically money from the poorer countries was sent back to the European countries. Environmentally the search for natural resources like gold and oil, destroyed and damaged the environment. The richer countries didn’t care very much about this. In recent years we have began to take better care of our planet but a lot of damage has already been done.
