Wireless communication Essay Example

Wireless communication Essay A type of wireless communication that is most familiar to mobile phones users. Its called cellular because the system uses many base stations to divide a service area into multiple cells. Cellular calls are transferred from base station to base station as a user travels from cell to cell. (Bellis) History * First concept introduced in 1947 * Incorporated technology from car phones * Purely theoretical and no technology existed to support * Dr.Martin Cooper, a Researcher for Motorola is credited with inventing the first cellular phone * The First Cell Phone The first cell phone was named the DynaTAC8000X. It was created by Martin Cooper in 1984. It took over a decade to develop and $100 million. There were only about 2,000of these cell phones available to the public. * Weight- 2 pounds could store only 30 phone numbers. Battery needed to be charged for 10 hours. Talk time- 1 hour! The phone cost $3,995!! Uses * Text messaging Entertainment Uses: Games, music (mp3 player), books (e-boo k), and digital television broadcast * Social Uses: phone  call, text message, wireless internet (access to e-mail, social networking websites) * Organization Uses: calendar, finance manager, address book, storage for data * Hospital Uses: Used to view image (x-ray, MRI, etc). Means  of communication between nurses and clinicians. * Museum Uses: audio guide is provided through cell phones. * Educational uses: mobile learning provides access to lectures and test preps. * Track the culprits, location of a person   Cell Phones revolutionized long distance calling, making it much more inexpensive for long distance communication. * Cell phone logs have also been helpful in court cases where they can be used as evidence. * Smart Phones arent only used for communication, but for organizing schedules, jotting down notes, playing music, games, checking the weather, and other applications How do mobile phones work? Mobile phones and their base stations transmit and receive signals using electromagnetic waves (also referred to as electromagnetic radiation or fields, or radio waves).Electromagnetic radiation is emitted by many natural and man-made sources and plays a very important part in our lives. All electromagnetic radiation consists of oscillating electric and magnetic fields and the frequency, for ? (nu), which is the number of times per second at which the waves oscillate, determines their properties and the use that can be made of them. Frequencies are measured in hertz or Hz, where 1 Hz is one oscillation per second,1 kHz or kilohertz is a thousand Hz, 1 MHz or megahertz is a million Hz, and 1 GHz or gigahertz is a thousand million Hz or 109 Hz.Frequencies between about 30 kHz and 300 GHz are widely used for telecommunication, including broadcast radio and television, and comprise the radiofrequency (RF) band. Cellular mobile phone services operate within the frequency ranges 872–960 MHz and 1710–1875 MHz. An RF wave used for radio communicat ion is referred to as a carrier wave. The information it carries – speech, computer data, etc – has to be added to the carrier wave in some way, a process known as modulation. The information can be transmitted in either analog/ Digital form. Mobile Net workA mobile phone sends and receives information (voice messages, fax, computer data, etc) by Radio communication. Radiofrequency signals are transmitted from the phone to the nearest base station and incoming signals are sent from the base station to the phone at a slightly different frequency. Once the signal reaches a base station it can be transmitted to the main telephone network, either by telephone cables or by higher frequency (such as 13, 23 or 38 GHz) radio links between an antenna (eg dish) at the base station and another at a terminal connected to the main telephone network.These microwave radio links operate at rather low power and with narrow beams in a direct line of sight between the antennas, so that a ny stray radiation from them is of much lower intensity than the lower frequency radiation transmitted to the phones. Radiation Pattern of a Cell tower Signals to and from mobile phones are usually confined to distances somewhat beyond the line of sight.They can reach into buildings and around corners due to various processes including reflection and diffraction, that allows the radiation to bend round corners to some degree, but the coverage area from a base station is partly governed by its distance to the antenna’s horizon. An ideal network may be envisaged as consisting of a mesh of hexagonal cells, each with a base station at its centre but in practice the coverage of each cell will usually depart appreciably from this because of the topography of the ground and the availability of sites for the base stations.The sizes of the cells are usually less than the 35 km maximum because obstruction by hills, buildings and other ground features reduces the effective range. Freque ncies are reused several cells away and the capacity of a network (the number of simultaneous phone calls which may be made) depends on the extent of the frequency spectrum available, the cell diameter and the ability of the system to work against a background of interference from other cells.To accommodate the steadily increasing volume of users, cell sizes have to be progressively reduced (for example, by using base station antennas of lower height and reduced power) so that the frequencies may be reused more often. Indeed in large cities, base stations may only be a few hundred metres apart. Power output of the base stations are naturally more powerful and continuous in nature and they are received at close quarters for a longer period of time. People are not supposed to reside within 100 meters from the base stations in urban areas and within 300 meters in rural areas.Measure of RF Density: A SAR value is a measure of the maximum energy absorbed by a unit of mass of exposed tiss ue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue CDMA mobiles like those of Reliance and Tata Indicom have 1 Watts output; The GSMA mobile like BSNL, Idea and Airtel have 2 Watts and the US Analogue mobiles have a power output of approximately 3. watts. The SAR rating of each individual phone model is now being displayed on all mobile phone packaging in both the US and the UK, which will enable users to make informed choices when purchasing a handset. SarValues. Com brings this important information free of charge to all cellular users and also provides useful links to other Websites containing information. Whatever the outcome of the mobile phone debate, it makes sense to use prudent measures to reduce your radiation exposure, if possible.An obvious way to accomplish this, is by choosing a phone with a lower Sar Value. The point is to show that SAR Is not a property of a device itself, but a combination of a device and the way it is used. Mobile phones are now a large part of our every day life, they are probably the most useful gadget ever invented! The thing is though, every now and again research comes forward suggesting that mobile phones should be used responsibly, as the evidences are fast coming up to be displayed having its impace in Human health, environment and society.Biological Effects : Many scientific studies have investigated possible health symptoms of mobile phone radiation. These studies are occasionally reviewed by some scientific committees to assess overall risks. A 2007 assessment published by the European CommissionScientific Committee on Emerging and Newly Identified Health Risks (SCENIHR ) concludes that the three lines of evidence, viz. animal, in vitro, and epidemiological studies, indicate that exposure to RF fields is unlikely to lead to an increase in cancer in humans. Thermal effects :One well-understood effect of microwave radiation is dielectric heating, in which any dielectric material (such as living tissue) is heated by rotations of polar molecules induced by the electromagnetic field. In the case of a person using a cell phone, most of the heating effect will occur at the surface of the head, causing its temperature to increase by a fraction of a degree. In this case, the level of temperature increase is an order of magnitude less than that obtained during the exposure of the head to direct sunlight. The brains blood circulation is capable of disposing of excess heat by increasing local blood flow.However, the cornea of the eye does not have this temperature regulation mechanism and exposure of 2–3 hours duration has been reported to produce cataracts in rabbits eyes at SAR values from 100-140W/kg, which produced lenticular temperatures of 41 °C. There were no cataracts detected in the eyes of monkeys exposed under similar conditions. Pre mature cataracts have not been linked with cell phone use, possibly because of the lower power output of mobile phones. Non-thermal effect: The communications protocols used by mobile phones often result in low-frequency pulsing of the carrier signal.Whether these modulations have biological significance has been subject to debate. Some researchers have argued that so-called non-thermal effects could be reinterpreted as a normal cellular response to an increase in temperature. The German biophysicist Roland Glaser, for example, has argued that there are several thermoreceptor molecules in cells, and that they activate a cascade of second and third messenger systems, gene expression mechanisms and production of heat shock proteins in order to defend the cell against metabolic cell stress caused by heat.The increases in temperature that cause these changes are too small to be detected by studies such as REFLEX, which base their whole argument on the apparent stability of thermal equil ibrium in their cell cultures. Other researchers believe the stress proteins are unrelated to thermal effects, since they occur for both extremely low frequencies (ELF) and radio frequencies (RF), which have very different energy levels.Another preliminary study published in 2011 by The Journal of the American Medical Association conducted using fluorodeoxyglucose injections and positron emission tomography concluded that exposure to radiofrequency signal waves within parts of the brain closest to the cell phone antenna resulted in increased levels of glucosemetabolism, but the clinical significance of this finding is unknown. Blood–brain barrier effects: Swedish researchers from Lund University (Salford, Brun, Persson, Eberhardt, and Malmgren) have studied the effects of microwave radiation on the rat rain. They found a leakage of albumin into the brain via a permeated blood–brain barrier. This confirms earlier work on the blood–brain barrier by Allan Frey, Osc ar and Hawkins, and Albert and Kerns. Other groups have not confirmed these findings in in vitro cell studies or whole animal studies, however Frey alleges that an editor determined that a researcher who claimed that his attempts to replicate Freys research had not validated Freys results had incorrectly interpreted his own results, and that his research had confirmed Freys results.Cancer: The International Journal of Epidemiology published a combined data analysis from a multi national population-based case-control study of glioma and meningioma, the most common types of brain tumour. The authors reported that the wall of capillaryblood vessels situated in the brain are very thin made up of single layer of endothelial cells. Microwaves trigger changes to protein structures in endothelial cells,allowing toxins to enter the brain and making them tumorous. Mobile phones can affect pacemakersUnder certain circumstances, mobile phones can have adverse effects on the function of pacemake rs, but the devices usually start working properly again once the phones are moved away, researchers in Turkey report. The most essential recommendation to patients according to thereport is that mobile phones must be kept at least 20 cm away from pacemakers. For this purpose, it is sufficient for patients not to use the ear on the side of the pacemaker while talking on the mobile phone and not to carry the mobile phone in the shirt pocket on the side of the pacemaker.Infertility Problems : Using a hands-free device with a cell phone may affect fertility if phone is kept close to the testicles, Cleveland Clinic researchers warn in the journal Fertility and Sterility. Men who use these hands-free devices tend to carry their cell phones in their pants pocket or clipped to their belts at the waist while in talk mode have impact on semen quality. As a result, they may be exposing their testicles to damaging radiofrequency electromagnetic waves, explains Ashok Agarwal, PhD, head of the a ndrology laboratory and the irector of the Center for Reproductive Medicine at the Glickman Urologoical and Kidney Institute at the Cleveland Clinic in Ohio. Cell Phones Effect on environment: We are living in an environment filled with artificial radiations. The electromagnetic radiation playing role in the decline of animal and insect population. The EMR is so powerful that it affects the biological systems of birds, insects, even humans. In September 2010, the ministry established a ten member committee under Bombay Natural History Society (BNHS) with director Asad Rahmani to study the impact of cell phone towers on birds and bees.This group of experts reviewed 919 studies performed in India and abroad. Of the 919 studies, 593 showed the negative impact of mobile towers on birds, bees, humans, wildlife and plants. Effect on farm animals * Dairy cows- Decreased milk production, spontaneous abortions, reproductive and developmental problems, and general decline in overall health. * Sheep dogs, cats, rabbits living near base stations affected. Cell phones and Birds * Sparrows have disappeared completely from the cities at least four years ago in Britain as mobile phones grew in popularity. 3G mobiles were introduced in 2003; there are 65 million users in UK by 2005. In a research by Spain conservation biologist Alfonso Balmori there is difference in how the birds behaved close to the phone antennae. * Young birds die from unknown causes. Bird couples frequently fought, while constructing their nests stick fell to the ground. * Some nests were never completed and the storks remained passively in front of antennae. * Laboratory studies show bird embryo die when exposed to microwaves. Effect on Biodiversity * Electromagnetic radiations of mobile phones are directly related with the disturbance in ecosystem and ultimately biodiversity. 230 species (several million birds) die each year from collisions with telecommunications in the United States during migration. * Birds have thin skulls. Accidents happen mainly in night, in fog, bad weather when birds might be using the earth’s magnetic field for navigation. Effect on chicks According to a study 75% chick embryos died due to exposure to cell phone Effect on rabbits 2 to 3 hours exposure of rabbits to electromagnetic radiations showed cataracts because cornea doesn’t have thermal regulation. Bacteria and cell phones:The problem with phones is that we are in constant contact with them, and we spend a lot of time in close proximity to our faces and mouths and because it’s an electronic device, most people are hesitant about cleaning them. The cell phone has 10 times more germy than a toilet seat. Infectious microbes on the surface of a Smartphone including staphylococcus have an excellent chance of making their way to your eyes, nose and mouth Effect on Honey bees: Scientists may have found the cause of the worlds sudden dwindling population of bees and cell phones may be to blame.Research conducted in Lausanne, Switzerland has shown that the signal from cell phones not only confuses bees, but also may lead to their death. Over 83 experiments have yielded the same results. With virtually most of the population of the United States (and the rest of the world) owning cell phones, the impact has been greatly noticeable. Led by researcher Daniel Favre, the alarming study found that bees reacted significantly to cell phones that were placed near or in hives in call-making mode. The bees sensed the signals transmitted when the phones rang, and emitted heavy buzzing noise during the calls.The calls act as an instinctive warning to leave the hive, but the frequency confuses the bees, causing them to fly erratically. The study found that the bees buzzing noise increases ten times when a cell phone is ringing or making a call aka when signals are being transmitted, but remained normal when not in use. The signals cause the bees to become lost and disoriented . The impact has already been felt the world over, as the population of bees in the U. S. and the U. K. has decreased by almost half in the last thirty years which coincides with the popularization and acceptance of cell phones as a personal device.Studies as far back as 2008 have found that bees are repelled by cell phone signals. Bees are an integral and necessary part of our agricultural and ecological systems, producing honey, and more importantly pollinating our crops. As it is unlikely that the world will learn to forgo the convenience of cell phones, it is unclear how much they will contribute to the decline of bees, and their impact on the environment. Effects of cell phones on society The effects of cell phones on society will always be a double edged sword. The debate is never ending.Both sides have compelling arguments. But although there are some disadvantages, when looking around, one of the first sights I see are people walking with one hand up to their ear, like an e vidence that cell phones have become important in our daily life. One effect of cell phones on society is availability to keep in touch with family, friends or business partners almost in every place and every time. You do not have to wait until evening, when you will be at home, or find a telephone boxes to call some friend or family member, if you have to tell them something important.Moreover – cell phones are the perfect way to stay connected with others in the event of emergency. They provide us with a sense of security. In the event of emergency or loss cell phone can allow others to connect with you quickly and could possibly save your life. If you feel insecure or something has happened to you or to a person next to you, you can call to get help. For instance, most of Americans (about 74%) who use cell phones say they have used their mobile device in a critical situation and gained valuable help. Besides that today cell phones are more and more easily to use.They are capable of not only receiving and making phone calls, but taking, sending and receiving photos, sending data, you can use the Internet to check your e-mail, a calendar to plan your time, an alarm clock or a calculator. In short – nowadays cell phones are useful in different daily situations. But all opinions could never be the same. Some people believe that cell phones influence us negative. They say – health problems are one of the results of owing a cell phone. That is because of the negative radiation, what they have, when the phone is in your pocket or next to you.However scientists still have not proved the badness of.. Recommendations: The International Commission for Non-ionizing Radiation Protection is the authority for monitoring Ionizing radiation of mobile phones and Base Stations. This body has spelled out definite guidelines for the radiation levels allowed and the base station lists are classified accordingly Now let us see the recommendations for safe us e of mobiles: Various steps to be followed to decrease the burden of Radiation Effect: * Step1 Minimize the duration of use, since certain effects of electrmagnetic radiation (e. . thermal effects on brain) are accumulative. One should not talk for more than three minutes at a stretch and should take at least 15 minutes break in between calls. * Step2. Use hands-free to decrease the radiation to the head. Accidents caused by inattension are still there in this situation. * Step 3. Keep the cell phone away from the body. Use a speaker phone or the head set. * Step 4. Limit the use of cell phone by children. * Step 5. Avoid living near the base stations * Step 6. Avoid phone usage while crossing the street. * Step 7.Never use a cell phone when a conventional phone is available. * Step 8. Mobile phones should be prohibited near Intensive Care Units and Operation theatres. * Step 9. The practice of installing antennas needs to be regulated. * Step 10. The specific absorption rate (SAR) value for each hand set should be provided by the manufacturers on the website as well as in the user’s manual, as per the International Commission on Non-Ionizing Radiation Protection guidelines. * Please take this into consideration and use caution on your phones. * You tell everyone on the road and off the phone.Future Perspectives: As the present day world is more dependent on Mobile phone in their day to day life ,there is need for researcher to discover mobile phones that emit less radiation. RADISAFE  , is one such invention. It is an anti radiation mobile chip reduces over  99. 95%  of radiation emitted from your mobile phone, and makes your mobile phone totally harmless as certified by the worlds premier electronics testing laboratory,  california institute of electronics and materials sciences, USA. But for its application in the market , there is a long way to go.

Free Essays on Money Laundering

Financial Accounting For Financial Services Assignment Money Laundering The word money laundering, according to the myth, is derived from Al Capone's practice of using a string of coin-operated launderettes in Chicago to disguise his revenues from gambling, prostitution and protection rackets. It's a nice story but not true, money laundering is so called because it perfectly describes the process of removing the stains and smells which money acquires when criminals earn it. In this report I will go on to discuss the topic of money laundering in the following order; firstly, I will begin by explaining what is money laundering?, why it is done?, and how it is done? I will then go on to explain the effects of money laundering and the institutions/organisations that are at risk from these activities. I will also be discussing the current situation in the UK regarding money laundering and whether anything can be done to prevent or restrict laundering activities, and will then go on to conclude my findings. Money laundering is the process by which criminals attempt to conceal the true origin and ownership of the proceeds of their criminal activities. If they are successful they can then maintain control over the proceeds and, so, provide a legitimate cover for their source of income. J.D. Mclean defined money laundering in the International Judicial Assistance as: "Although the proceeds of crime will be kept as capital for further criminal ventures, the sophisticated offender will wish to use the rest for other purposes. If this is to done without running a risk of detection, the money which represents the proceeds of the original crime must be "laundered"; put into a state in which it appears to have an entirely respectable provenance" It is important to bear in mind that money laundering is a process (often a highly complex one) rather than a single act.

12 Angry Men

12 Angry Men Essay Many movies start with promising premises that end up only partially fulfilled, but 12 Angry Men Essay never disappoints. The rich drama with minimalist sets occurs almost completely within the confines of a jury room. The incredibly strong ensemble cast for the jury includes: Henry Fonda, Lee J. Cobb, Ed Begley, E.G. Marshall, Jack Warden, Jack Klugman, Edward Binns, Joseph Sweeney, Martin Balsam, George Voskovec, John Fiedler and Robert Webber. To further minimize distractions, we never learn most of the jurors names. We know them by their opinions, backgrounds and weaknesses. They have their juror numbers, and that is considered sufficient labeling. As the story opens, a bored judge in a capital murder case is reading his charge to the jury. When he comes to the part about a reasonable doubt, he repeats it with such an emphasis that he seems to be suggesting that any doubt they may have in their minds about the defendants guilt is probably not reasonable. Indeed everyone, including the defendant, seems to think the case is hopeless. The accused, played with big, soulful eyes by John Savoca, never speaks, but his sunken, despondent demeanor says it all. The evidence in the case is clear, and as we find out later, his attorney apparently was pretty inept. Before the jurors start their deliberation, they idle away their time arguing over whether the case was dull or not and over how well the attorneys performed. If you didnt know better, you could assume they were reviewing some movie they had seen. None of them seems to be concerned in the least that the defendants life is at stake. Into this sure and certain world comes a voice of caution, someone who is willing to demand that the jurors put a halt to their headlong rush to judgment. This voice of reason comes from a juror played by Henry Fonda, giving a resolute and perfect performance that should have at least gotten him an Academy Award nomination for best actor, but didnt. Fondas character votes not guilty on the first ballot, not because hes sure the defendant is innocent, but because he wants to get his fellow jurors to stop and reconsider the merits of the case. The other jurors are aghast that he seems to have forgotten the sure and certain facts of the case that prove the defendants guilt. Now these are facts, barks an angry juror played by Lee J. Cobb. You cant refute facts. Everyone brings their differing lifestyles into the jury room. E.G. Marshall plays a prim and proper Wall Street stockbroker. He ticks off the facts in the case as if he were reading closing stock prices from the newspaper. His studious and ever-stern glare cuts down those who disagree with him. And he is the only one who keeps his coat on the entire time-he claims he never sweats, even in the stiflingly hot jury room. His bankers glasses, one of the films few props, turn out to be key to the cases solution. With superciliousness, he bemoans slum dwellers such as the defendant, only to find out that another juror, played by Jack Klugman, grew up in the slums and resents the brokers remarks. Although most jurors are known by the intensity of their convictions, Robert Webber plays someone who works in advertising and views serving on a jury no more seriously than he would concocting a laundry soap jingle. He tries using advertising lingo such as run this idea up the flagpole and see if anybody salutes it. After ridicule and scorn by his fellow jurors, Henry Fondas character suggests a startling compromise. He will abstain from the second ballot, and if they all vote guilty, so will he. But if he has garnered any support for the defendant, then the rest of the jurors have to agree to stay awhile and discuss the case with him. After he wins that round, one by one, the other jurors begin to fall in line behind him, but even if the conclusion is obvious, the way they get there constantly surprises and fascinates. The beauty of Roses script is that we come to know each of the jurors by the end of the deliberations. Most writers would gloss over some of them to concentrate on a few, but Rose gives each a unique personality and background. extroverted marmalade salesman, who made $27,000 last year and has tickets to tonights ball game burning in his pocket. He wants to vote .

Industrial safety engineering (safety in work enviroment) Term Paper

Industrial safety engineering (safety in work enviroment) - Term Paper Example The government regulations on organizational safety and health (OSHA) demand that organizations maintain health and safety standards to ensure that their employees work in a minimum risk working environment. Failing to comply with these regulations attracts legal penalties that often are consequential to the organization. One of the superior ways of maintaining health and safety within an organization is educating the employees on the need for safety in a working environment and the minimum safety level requirements demanded in the organization. The management should thus be aware of how to induce effective training programs and how to align the employees towards the managerial objectives as far as health and safety is concerned within the work place. In reality, employee training is a key strategy to minimization of accidents, illnesses and death in work environments. Safety and health are two closely related terms yet very distinct in an industrial setting, hence the need to separa te them. Goetsch (2008), an industrial and safety professional, define safety in an organization as the ability to keep the employees away from the accident-causing situations that might cause damage, injury or even kill the employee. For instance, in an engineering firm, engineers have to operate electrically driven machines such as conveyor belts and grinders. When such machines come into contact with human beings, they are likely to cause accidents, some of which may be fatal. As such, it is crucial to safeguard the life of an employee from such machines to avoid unnecessary accidents in an organization. On the other hand, health maintenance refers to the ability to protect employees from disease causing environments. In industrial organizations, say a manufacturing plant, employees are exposed to smoke that may cause lung diseases. In this light, organizations have a core responsibility to avoid accidents and industrial related diseases within the employee population. In the Uni ted States the Organizational Safety and Health Act (OSHA) provides the standards that industrial organizations should comply with. The OSH Act provides that each business organization has a general duty to ensure that their employees are safe and free work environment hazards. Each year, the federal government, through their safety supervisors, conduct random safety inspections to observe whether organization have applied safety programs that comply with the OSHA standards. Over 50, 000 organizations are scrutinized and failure of compliance attracts fines, penalties and even temporary or permanent closure of organizations. One requirement of the OSH Act is that the employees have the â€Å"right-to-know† the health risks and conditions of the organization before they are assigned to their duties (United States Department of Labor, 2013). Resultantly, the act recommends that every organization implement an employee training program to ensure that employees are aware of the d angers that they risk in their working conditions. In essence, the implementing a health and safety training program is a compulsory requirement for every organization. Putting the legal side of organizational health and safety aside, a healthy working environment has many economic benefits to the organization. Burton (2008) points out to the high financial cost that organizations pay for failing to implement standard work environment conditions. First, unhealthy employees are likely to absent from

Interagency Prevention and Planning Failures- Hurrican Andrew Research Paper

Interagency Prevention and Planning Failures- Hurrican Andrew - Research Paper Example With each disaster, the US government set up different agencies and bodies to provide help and succor to survivors of the aftermath. The method of providing aid and succor had clear sections of authority and a clear identification of which agency was to do what tasks (Nudell, 1988). Unfortunately, the precision with which these agencies were supposed to work did not happen. These agencies had turned into ‘stove pipes’ and did not cooperate with each other. With very little interagency cooperation, the various federal agencies that were seized with providing help were left powerless and tangled up in bureaucracy and red tape. The result was that thousands of people could not be evacuated to stations built specifically for such tasks. Billions of dollars in funds that were used for infrastructure were wasted (Herman, 2010). This report discusses and focuses on the poor interagency prevention and planning that contributed to the disaster after Hurricane Andrew struck Florida. Morton (2008) has commented on the structure and functioning of the national security and the defense forces that have ambiguous security roles and function and which serve the President of USA. These departments have strong workforce cultures and a deep seated desire to protect their turf and this created stove pies in the departments of national security. These entities tend to work in isolation and prefer to be the bearer of good or bad news. Various departments such as the Office of the Director of National Intelligence - ODNI, Department of Justice - DOJ under various acts ranging from the National Security Act 1947 to the Intelligence Reform and Terrorism Prevention Act, 2004 have never managed to bring the various departments to act in a cooperative manner and where a common culture exists. The various national security acts and state security at the national and state levels are uneven. A critical review of Shelby (2011) shows that at the time when

Comparing Power in Cask of Amontillado, Rappaccinis Daughter, and Bart

Power in Poe's Cask of Amontillado, Hawthorne's Rappaccini's Daughter, Melville's Bartleby the Scrivener, Phelps' Angel over the Right Shoulder and Child's The Quadroon In Poe's The Cask of Amontillado Montressor seeks his revenge (for an imagined offense) on Fortunado. He manipulates Fortunado into beliving that he is a friend and that they are going through the crypt. He uses Fortunado's "weak point" --his love of alcohol-- against him. He creates the illusion of concern by insisting that they turn around to save poor Fortunado's health. Montressor manipulates the entire situation from beginning to end. His greatest achievement is that Fortunado would know what was happening to him by dying a slow death and more importantly, he would know who was behind the elaborate plan for his death. Montressor (who is mentally unstable) is a corrupt man who thrives off of the power he has (had) over Fortunado. In Hawthorne's Rappaccini's Daughter we find two instances of a power struggle and manipulation. The Scientist has used his daughter in an experimental attempt to give her a one-of-a-kind gift. Failing in his attempt he has in a sense "cursed" his daughter. He has taken away her power to choose her own life--she is at the mercy of her "gift" and is suffering the results of his ambition. Baglioni uses Giovanni in a different way. He uses Giovanni to gain power over Rappaccini. He manipulates Giovanni into thinking that Rappaccini is corrupt and that Beatrice can be saved by his antidote. Rappaccini is corrupt because he uses his daughter to practice his scientific experiments. If his intention to enable her with a gift was indeed genuine then he may not be as "wicked" as Baglioni. Baglioni's intentions were purely evil. He man... ... the characters in this story are all manipulated and repressed by the power of the social code of the time regarding quadroons. Everything in the story hinges not only on the social pressures, but also on the fragility of love. She belives that he will love her (even though he is not legally bound to her) and together they could face the injustice of the world or merely hide from it. Due to his ambition, he betrays her and leaves her and his daughter. He does no service to either of the three women--his common-law wife by breaking her heart and leaving her to cope with a child, the child left without a father and a social outcast, and his new wife by marrying her just for the social and economic position it would bring him and especially since she learns that he is still in love with the other woman. The victims in this story are manipulated by one man's ambition.

How Far Was Political Opposition to the Tsar Divided 1881-1905?

How far was political opposition to the Tsar divided in their aims and methods, 1881-1905? Political opponents of the Tsar were clearly divided in their aims and methods, and consequentially may have contributed to the survival of Tsarist Russia. The main parties were the Social democrats (Bolsheviks and Mensheviks), Social Revolutionaries and Liberals (Octobrists and Kadets). Each of these radical parties had their own separate beliefs on what Russia needed and each aimed for some sort of change. However, within the groups, there were many issues, which they refused to work with each other to solve.The SR believed that Russia’s future lay with the peasantry and so they wanted to give peasants their own land and improve living conditions for working classes. They used tactics such as terrorism and assassinations, such as the assassination of Alexander II. The Liberals also aimed to deal with these social problems facing Russia while establishing a democracy. However, the Liber als, especially Octobrists, did not agree with the violent tactics. They preferred votes and discussions as a way to put across their opinion. In fact, the Liberals were the most moderate of all the radical parties in Russia.They wanted to abolish autocracy and have the power shared between a democratic government. Similarly, the Social Democrat party also wanted to establish a democracy but, once again, without their aggressive methods. While the SR had a terrorist wing, the Bolsheviks and Mensheviks preferred using propaganda campaigns. Although there are some similarities in the aims of the parties, the major differences in methods used meant that each group’s strength alone was not enough to achieve their own specific goals and even though the groups did have some tactics such as propaganda in common, it was not enough.The parties all also pursued support from different groups of the population. For example, while the Liberal Kadets got support from the educated middle cl ass, the Bolsheviks sought support from dedicated revolutionaries. Therefore, with no one party gaining support from a majority, it was hard for one to stand out and become a major threat to the Tsar at the time. Support came from the way each party appealed to the public. For example, while the SR carried out a wave of political assassinations in order to onvey their drastic belief of abolishment of Tsarism, their ideas of peasant ownership of land would spread and so peasants would support them and so would radical revolutionaries. In this way, they developed the â€Å"Russian Union of Peasants. † However, people who believed in non-violent methods would support the Liberals who are more moderate. This way, the parties will not get enough support to stand a chance against the main reasons why Tsarism should stay. These include the church, the belief of the divine right, the army and the Okhrana which were very effective in keeping the Tsar in a state of power.
