Free Essays on Persuasive Appeal Analysis

PERSUASIVE APPEAL ANALYSIS When we, as an exposed audience or even more specifically as the constructed or target audience, view television or are â€Å"exposed† to radio, we are â€Å"exposed† to mass media. The commercials within this type of advertising that we come into contact with are not normal of public communication, they are persuasive and designed to make us, the viewer or audience, want to go buy what the manufactures are selling. There are many companies in the competitive marketing industries which of whom succeed and also many unfortunately failures. There are many comparisons and even more distinguishes between companies which succeed and those which fail. These differences which set the companies which fail apart from those that have succeeded is their ability to win over their customers and sell the product being manufactured. In any type of persuasive communication, which is both public and successful the person who is exposed to the images may not realize what they are looking for in a commercial for a product which they didn’t even know that they needed. Therefore, many advertisement agencies include a credible source to present the context, also an attentive getter, a type of self image for which the audience to relate with. They also put forth the effort to convince and/or persuade the consumer to buy their product instead of another product. After reviewing several commercials and comparing their good and bad points, as I have stated before, this is my conceptual analysis of the commercial that I think is the m ! ost successful and/also the most convincing (about buying the product being advertised) which is currently being advertised.

Advantage And Disadvantages Of Fixed Wing Versus Rotor Wing Engineering Essay

Advantage And Disadvantages Of Fixed Wing Versus Rotor Wing Engineering Essay Since 1919, law enforcement agencies have used fixed wing and rotor wing aircrafts to assist in enforcing the law. In 2007, data from the Bureau of Justice Statistics showed that large law enforcement departments provided aerial enforcement in the District of Columbia and 46 states. There were 295 airplanes and 604 helicopters being operated, which flew more than 330,000 missions. http://bjs.ojp.usdoj.gov/content/pub/pdf/aullea07.pdf The types of airplane that are used by law enforcement are Cessna 182, Cessna 206, Pilatus PC-12 Spectres, P-3 Orions, Citations, Learjets, Gulfstream jets, King Air 350s and 200s and some larger airliner-type aircraft. Some of the helicopters used are the American Euro-copter EC120/130/145, AStar AS350/355N/350 B2, Dolphin HH-65C, Blackhawk UH-60, Maverick, Raven II R44, Cayuse OH-6 and McDonnell Douglas MD 600. The types of missions these aircrafts conduct are surveillance, drug interdiction, fugitive searches, routine patrol or support, search and re scue, personnel transport, prisoner transport, SWAT operation, traffic enforcement, speed enforcement, homeland security, photographic, medical support and evacuation. Both types of aircrafts have their advantages and disadvantages in airborne law enforcement. http://www.kansas.com/2010/08/01/1427779/aviation-sees-growth-in-law-enforcement.html. The advantages that a helicopter has over an airplane are that they can land and take off without the need for run ways. Their airfoil shape rotors are like the wings of an airplane, as the rotor spins, air flow faster over the tops of the blades than it does under, thus creating lift for flight. Their unique rotor design allows for them to takeoff vertically, fly in any direction including sideways, backwards and hover over an area. Their ability to hover provides coverage for the ground units on the street and if needed land to assist in foot pursuits. They can be equipped with a winch for the purpose of lowering or picking up personnel or equipments on the ground, at sea or on mountains during a search and rescue mission, where there is no place to land . They are better able to maneuver around tall structures at lower altitudes. manhttp://library.thinkquest.org/J0112389/helicopters.htm. On 14 November 2008, San Diego Police Department ABLE helicopter used the FLIR camera to catch a man facing murder charges for beating another with a crutch in the middle of the street. http://www.policeone.com/police-products/tactical/night-vision/videos/5954944-police-helicopter-catches-bizarre-street-fight-on-flir-camera On 30, January 3013 the NYPD police helicopter rescues a shipà ¢Ã¢â€š ¬Ã¢â€ž ¢s captain who was having a heart attack. A dramatic nighttime helicopter rescue in New Yeark Harbor may have saved the life of a shipà ¢Ã¢â€š ¬Ã¢â€ž ¢s captain. Police say they received a call Tuesday night that the captain of the Panamanian cargo ship Grey Shark was having a heart attack. The NYPD harbor medical team stabilized the 6 0 year old captain before calling the help of a police helicopter. A basket was lowered to hoist him up into the chopper, which then flew him to Staten Island University Hospital North. He was listed in stable condition. http://www.ny1.com/content/top_stories/176246/police-helicopter-rescues-ship-captain-who-was-having-a-heart-attack The helicopters are force multipliers for ground units, because they can monitor the tactical environment, give alerts or observe things which the ground units are unable to detect. Additionally, they can respond and cover ground more quickly than ground units. The flight deck of a helicopter can be equipped with multiple electronic equipments. Electronic Flight Instrument System (EFIS) also know as glass cockpit that provides flight and system information to the crew, Forward Looking Infrared (FLIR) camera allows the crew to see images created from infrared energy, moving map system show their location, satellite phones provide direct communication, di gital video downlink gives real time images, night vision goggles can be used in low light situation if needed, loudspeakers for communication or message deliver to the ground, tear gas dispensers, police and aviation radios . Disadvantages helicopters are that they cost more to operate and maintain. A fully equipped helicopter can cost from $500,000 to $3 million and the flying costs ranges from $200 to $400 per hour. http://usatoday30.usatoday.com/news/nation/2007-09-30-cophelicopters_N.htm Maintenance, fuel, leasing and financing cost are three times then the cost to operate and maintain airplanes. Due to its abilities to fly lower and hover over areas it creates lots of noise and is easily detectable. The capacities of passengers that a helicopter can carry are limited. The Robinson RA-44 can carry 2 to 4 personnel and others like the Blackhawk UH-60 can carry 11 personnel or the Bell UH-1 that can be configured to carry 15 personnel. The general commercial helicopters used by t he law enforcement agencies have a flight time of two to four hours, with top speed from 50 to 200 knots and an average range of about 200 miles. The operations of fixed wing aircraft have some advantages over rotor wing aircrafts in law enforcement. They can perform a wide range of missions which requires them to stay airborne longer then a rotor wing aircraft is able to. Fix wing aircraft can carry more payloads and engine performances are great then those of rotor wing aircrafts. Aero surveillance, homeland security, speed enforcement and transport of people or gear are mostly the missions performed. http://www.lawofficer.com/article/patrol/fixed-wing-aircraft-law-enforc They are equipped with a variety of high tech equipments just as their rotor wing counterparts. The cabins are pressurized and allow for higher altitude flights. They can perform surveillance 5,000 ft to 6,000 ft and not be undetected. The average costs to maintain and operate a fixed wing aircraft per flight is about $54 for maintenance and $45 for fuel compared to a rotor wing aircraft. http://bjs.ojp.usdoj.gov/content/pub/pdf/aullea07.pdf The Custom Border Patrolà ¢Ã¢â€š ¬Ã¢â€ž ¢s P-3 AEW Orion airplane has a large fuel capacity of 60,000 lbs; flight time up to 10 to 13 hours, maximum range at low altitude is 2,500 NM and at high altitude 3,800 NM. Average cruising speed is 300 to 330 knots. It can carry a crew of 12 to 21 personnel. Normal crew consists of four systems operators, three pilots, two flight engineers and three maintenance crew members. This aircraft is integration with the E-2 Hawkeye aircraft radar system, which allows for it to see 200 NM in all directions. They coordinate and direct Navy and Coast Guard ship and aircrafts to the location of drug smuggling boats or planes. Primary mission are interdiction, over water operations, surveillance and homeland security. The use of this aircraft between the Jacksonville, Florida and the Texas office have contributed to the cap ture and seizure of 50 metric tons of drugs worth a roughly about 2 Billion dollars. http://www.youtube.com/watch?v=vqCtrB_FZvE Fixed wing light sport aircraft generally cost between $60,000 and $130,000 to purchase and $50 per hour to fuel and maintain. They can fly at wide range of speeds of 35 to 125 knots making them an excellent platform for performing a broad range of law enforcement missions. It can carry up to 500 lbs and travel twice as far as a helicopter could. http://nij.gov/nij/topics/law-enforcement/operations/aviation/types-of-aircraft.htm The disadvantages of fix winged aircrafts are they require a runway to take off and land, assembling of the flight crew, delay on taking off due to congestion at airport, unable to see the other side of the aircraft. They cannot monitor the tactical environment very well and or unable to alerts or observe things which the ground units are unable to detect. Unable to land and assist with foot pursuits, canà ¢Ã¢â€š ¬Ã¢â€ž ¢t hover, t he aircraft is not equipped with rescue winch.

Orientalism by Edward Said Movie Review Example | Topics and Well Written Essays - 1500 words

Orientalism by Edward Said - Movie Review Example United States, Said had the unique advantage of experiencing different perspectives on the issue of Palestine-Israel conflict as well as broader Arabian politics. His works on the subject of Middle East politics are informed by his first hand experiences at these places, as well as a careful study of preceding scholarship by Western intellectuals. The primary criticism in his book Orientalism, as also seen in the documentary, is directed toward the stereotyped vision of Arabs in Western media and academia. This phenomenon, Said notes, is not something new, for its origins could be dated back to the Napoleonic conquest of Egypt in late eighteenth century. Behind the Western stereotyping of the Orient is the underlying belief that the surveyed geographies and peoples are somewhat backward and unrefined compared to Western civilization. What is also evident is the process of homogenization, whereby the vast mosaic of Oriental culture, language, social norms and religious beliefs are bracketed and abstracted into a unified whole. According to Said, â€Å"Orientalism identifies a range of strategies by which 19th and 20th century scholars, writers and artists imposed their authority on the East. The Orient was represented as a theatrical stage affixed to Europe, a place where jaded aristocrats, earnest second sons and tyrannical explorers could discover timeless truths, or perhaps unimagined erotic delights. Stereotypes of eastern wise men and exotic harems removed the colonial world from history altogether, substituting a timeless realm. Orientals are seen not as people but as problems, subjects, races†. (Burrows, 1999, p.50) But the reality is far from such constructions, as accounts of people who live in different regions of the Orient attest to. And as Said suggests in the documentary film, this set of illusions about the Middle East is not accidental or due to scholarly oversight. Said identifies a subtle difference between the stereotyping of the

Catastrophic Cyberattack Essay Example | Topics and Well Written Essays - 500 words

Catastrophic Cyberattack - Essay Example A cyber attack has been defined as a computer-to-computer attack that undermines the confidentiality, integrity, or availability of a computer or information resident in it (O’Shea, 2003). Cyber attacks involve virus and worm attacks delivered through vulnerable exploit engines, denial-of-service attacks (DoS), web defacements of informational sites, and unauthorized intrusions into systems (Colarik, 2006, p. 84). According to the CSI/FBI 2005 Computer Crime and Security Survey, rate of losses from attacks are: viruses (33%), unauthorized access (24%), theft of proprietary information (24%), DoS (6%), net abuse (5%), laptop theft (3%), and financial fraud (2%) (Colarik, 2006, p. 83). But for a cyber attack to be successful, phases of attack must also be successful. The five phases of cyber attacks are reconnaissance, penetration, identifying and expanding internal capabilities, intruder damages the system, and removal of evidence of penetration or theft (Colarik, 2006, p. 83). Cyber attack penetrates the Supervisory Control and Data Acquisition (SCADA) system of a water supply system and poses detrimental effect over the system. Cyber Attack on a Water Supply System During the late 1990s, medium to large water utilities integrated IT and SCADA system.

Features of bluetooth technology Essay Example for Free

Features of bluetooth technology Essay The logo for Bluetooth is based on Runes surrounding the legend of Harald Bluetooth. Bluetooth the technology is based on communications central to man’s own personal space. Fundamentally Bluetooth operates within the Industrial, Scientific and Medical (ISM) band at 2. 4 GHz. It is a short-range wireless communication standard defined as cable replacement for a Personal Area Network (PAN) (see â€Å"Bluetooth†. Grolier Encyclopedia of Knowledge, pp. 87-94). Figure 1 is the Bluetooth Logo. A cable replacement standard has been defined because cables limit mobility of the consumer; they are cumbersome to carry around, are easily lost or broken. Often connectors are prone to difficult to diagnose failures; or are proprietary. To counteract these limitations Bluetooth is designed to be light and portable. It can be embedded to take the riggers of physical knocks and shocks. It includes standards and protocols to make it mobile, robust, reliable and not limited to one manufacturer (see â€Å"Bluetooth†. Grolier Encyclopedia of Knowledge, pp. 87-94). The operating band also fits the goals of Bluetooth, imposing requirements as a cable replacement. The cost needs to be comparable with cable. Reductions can be achieved by operating in the licence free 2. 4 GHz ISM band, keeping backward compatibility wherever possible lowers the cost of ownership by avoiding upgrades and having a relaxed radio specification enables single chip integrated circuit solutions. It also needs to be as reliable and resilient as cable and cope with errors and degradation caused by interference. For mobile devices it must be compact, lightweight, low power and easy to use (see â€Å"Bluetooth†. Grolier Encyclopedia of Knowledge, pp. 87-94). A. 1 Frequency Hopping We have addressed the reasons for the Bluetooth without delving into the ‘nuts and bolts’ of the technology to discover how it operates. For the majority of countries the ISM band used by Bluetooth is available from 2. 40-2. 4835 GHz, although some countries impose restrictions. In this band Bluetooth uses Frequency Hopping Spread Spectrum (FHSS) techniques in order to improve its immunity from interference (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). In unrestricted countries the radios hop in pseudo random sequences around all available channels, this equates to 79 RF channels with a channel spacing of 1 MHz. Starting at a base frequency of 2402 MHz then the frequency of the channels, f, can be expressed as: f =2402 + n MHz where, n, is the channel number with an integer value in the range of 0 to 78. In restricted countries a limited frequency hopping schemes with just 23 channels is used and is catered for in the Bluetooth specification. Both hopping schemes have a 1 MHz channel spacing making it possible to design a simple radio interface whereby the baseband only has to specify a channel number and the radio multiplies this up to the appropriate frequency offset (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). In this FHSS scheme there are 1600 hops per second, which is a hop every 625  µs. Part of this hop timing is taken up by the guard time of 220  µs allowing the synthesizer time to settle. The frequency hopping implements time division multiplexing as shown in Figure 2. The basis of the scheme has the Master device transmitting in the first 625 us slot, k, and here the Slave receives. In the next slot k = 1 the Slave is permitted to transmit and the master listens (see J.Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). Figure 2: Frequency Hopping, master and slave interact on corresponding slots The radio must be able to retune and stabilise on a new frequency within tight time constraints. This is pushed further when establishing a connection; the hop rate can be shortened to every 312. 5 us. As the radios are constantly hopping to different radio channels, this ensures that packets affected by interference on one channel can be retransmitted on a different frequency channel. To further enhance resilience both ARQ (Automatic Repeat reQuest) and FEC (Forward Error Correction) form part of the specification (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). One drawback with the normal hop sequence is the time taken for production testing. Bluetooth ensures adequate frequency coverage with a test sequence allowing the radios to be tested at a faster rate (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall).

Mary Warren :: essays research papers

Mary Warren is an important character in Arthur Miller’s play, THE CRUCIBLE. Much of the action in Act III revolves around Mary’s testimony in court. She is a kind and basically honest girl who tries to do the right thing, saving her friends from harm. However, throughout Acts I and II, Mary is a follower who allows Abigail Williams to negatively influence her good judgment. To make matters worse, Mary is terrified of Abigail’s threats. Because of her weak will, the reader isn’t certain if Mary will maintain the courage to help John Proctor to win his court case in Act III. Mary Warren’s basic goodness is demonstrated on many occasions. She has been hired by John Proctor to help his wife Elizabeth with household chores. Mary proves to be a kind girl who gets along well with Mrs. Proctor. Although Mary has become a court official in Salem, she still gets up early in the morning to clean the Proctors’ house. While in court, Mary passes the time by making Goody Proctor a present of a small rag doll called a poppet. Upset by the court proceedings, Mary tells Mr. Proctor that she is "all shuddery inside" because Goody Osburn will hang. When the poppet becomes false proof of witchcraft against Elizabeth, Mary willingly explains that the poppet is hers. She also makes a vain attempt to comfort John Proctor as the court officials drag his wife away in chains. A basic sense of honesty is another of Mary Warren’s traits. In Act I she goes to Salem to convince Abigail to tell the truth about what really happened in the woods. When the witchcraft scare gets out of hand, Mary joins Abigail and the other girls in falsely accusing women of being witches. These false accusations are motivated by hysteria. There is evidence that Mary really believes that the women in court are bewitching her. She tells the judge that she thought she saw spirits. The other girls were screaming, and before she knew it, Mary was screaming with them. When she realizes that there are no spirits, Mary is willing to be truthful. After Elizabeth Proctor’s name is brought up in court, Mary Warren defends her against the accusation. At the end of Act II, the reader hopes that the basic sense of honesty will remain strong enough to allow Mary to testify on behalf of the accused women in Act III.
