I. INTRODUCTION
RADIO frequency identification (RFID) technology is gaining
attention both from academicians and from practitioners.
RFID has the potential to serve as a fundamental technology
for ubiquitous services where both objects and people can be
identified automatically via attached RFID tags [35]. However,
with the promise of RFID technology come issues that need
to be addressed for its widespread acceptance by consumers.
For example, the use of RFID technology by retailers and government
agencies raises questions about potential violation of
personal information privacy [35], and potential security threats
to personal information [40]. Motivated by such issues, this
study proposes and validates a theoretical model of consumer
acceptance of RFID technology. The proposed model is developed
based on the extant literature and provides a theoretical
framework of the critical factors that determine the consumer’s
acceptance of RFID technology. A contribution of this paper
involves reviewing the technology acceptance model (TAM)

...chnology. Perceived usefulness is defined as the extent
that individuals believe their job performance is enhanced by
using a particular technology. Perceived ease of use is defined
as the extent to which an individual believes that using a particular
system is free of effort. TAM also postulates that perceived
ease of use is a predictor of perceived usefulness.
Researchers have utilized and validated TAM for use with
numerous types of technology [51]. Some studies suggest that
TAMsuccessfully predicts an individual’s acceptance of various
corporate information technologies [1], [8], [12], [39]. According
to Straub et al. [42], TAM may hold across technologies,
people, settings, and times. Recently, TAM has its footprints
in e-commerce [50], [51], and mobile service [46]. This study
expands TAMto the study of consumer acceptance of the RFID
technology.
Radio waves were first discovered in 1887, but radio itself was initially invented by Italian Guglielmo Marconi in 1895 (1). His biggest mentioned success was in 1901, when he managed to broadcast the letter “S” across the Atlantic Ocean (1). However, he focused primarily on point-to-point transmissions, not large scale broadcasts from one point (F). As such, three American inventors - Lee De Forest, Edwin Howard Armstrong, and David Sarnoff - took credit for making radio as it is today a success (F). De Forest was born and raised in Alabama and he thought of everything in terms of patents and eventually held more than 300, but many claimed that he simply stole the inventions of others (2). In 1900, he patented a device to enhance weak signals and in 1902, he formed the De Forest Wireless Telegraph Company (1). In the same year. Reginald Fessenden, a Canadian, invented the “electrolytic detector”, which later became the spade detector that brought De Forest so much fame (F). In 1904, John Fleming invented the oscillation valve, which later became De Forest’s audion, and De Forest won the gold medal at the St. Louis World’s Fair for his “spade detector” (F). De Forest gained quite a bit of fame by broadcasting music live from the Eiffel Tower and from the Metropolitan Opera; however, many believed that this was a scam and that he had actually had the device broadcasting the signal only a few blocks away (F). In 1906, he envisioned bringing music and voices to all American households, but as it turns out Canadian inventor Fessenden had already broadcasted a Christmas greeting and music to the crew of a ship off the coast of Canada on Christmas Eve a year earlier (F). In 1912, Armstrong became prominent by inventing regeneration, wh...
In the film Do the Right Thing by Spike Lee he is able to exactly unfold the problem of racial problems in America by playing with cinematic devices such as Mis-En-Scene, narrative and sound. The centering and focusing of certain physical aspects with the use of camera angles and camera framing and movement ,the quick style editing s and transformation of sound all contribute to film's overall meaning. In analysing the sequence starting with a young child drawing a chalk portrait in the middle of the street and finishing with Sal, the pizza guy, making Radio Raheem look like a hoodlum straight out the gutters that does not know any better. These symbols are seen to create the hatred shared with African Americans and white working class Americans.
Now let us step to the other side of the Merchant counter as a consumer and realize how RFID can benefit the average person. Have you ever felt impatient when standing behind someone in line at the grocery store who insisted on paying by check? Well, get ready to get agitated at the slowpoke of the future—the techno challenged person using a credit card. Contactless cards, already used in Asia for several transit and payment systems, have been introduced to the United States via pilot programs sponsored by American Express and MasterCard. Thes...
War of the Worlds is an out of the box radio play that changed the world of mass communication forever and allowed the entire nation to see power of imagination and the unique power of radio over its audience. The creators of this nationwide hysteria were Orson Welles and the Mercury group. Orson Welles was a famous American actor, producer, director and radio broadcaster. In an effort to increase the shows audience, Orson Wells catered the idea of a Halloween public scare. The War of the Worlds radio play was a dramatization of H.G. Well’s novel The War of the worlds (1898 novel relating the story of an alien invasion on Earth) and performed as a scary Halloween episode on of the radio show Mercury Theater On The Air. The episode was aired over the Columbia Broadcasting System (CBS) on October 30th, 1938. The first two thirds of the 62-minute broadcast were presented as a series of simulated news bulletins, which suggested to many listeners that an actual alien invasion by Martians was currently in progress. Orson Welles’s scripted act was so convincing that the broadcast caused hysteria throughout the nation as several listeners believed that the nation was actually being invaded by Martians in a seemingly unstoppable attack. Many people were terrified by the news, and they left their homes in panic and fled. The aftermath of the broadcast was so disastrous that even Welles and his team were shocked. This 1938, 62 minute broadcast truly changed the meaning of mass media and everybody came to realize the true potential and power of mass communication.
The simplest of task have been made simpler, yet not only is this the future but it’s the now. Radio Frequency identification technology is technology that was created from Identification friend or foe or other wise known as (IFF). This later brought to life RFID, (Radio-Frequency Identification). The purpose of RFID varies has multiple purpose and multiple looks, but the results are all the same. There are multiple looks and shapes to these tags, some come in stickers, plastic, and even chips that would be implanted. Originally During World War 2 a British engineer Watson-Watt, developed the first active identify friend or foe (IFF). The purpose was to identify aircrafts that where returning to base. According to rfidjournal.com, IFF either reflects back a signal or broadcasts a signal. Thus creating RFID the modern tracker. The sizes of the transmitters varied from plane to plane, but ground troops had special readers that allowed them to identify the aircrafts. The implications of these modern methods of tracking later led to develop RFID tags. During the 50’s and 60’s the worlds scientist begun to research how advancements in radio frequency could be harnessed, it became emanate that this advancement would be used to track packages for consumers world wide. The first patents for RFID was America Mario W. Cardullo, he claims to have the first United States patent for an RFID tag with rewritable memory during 1973. That same year, a man named Charles Walton, received a patent for a RFID tag to unlock a door without a key. The RFID tag had an embedded transponder, which communicated a signal to a reader near the door. When the reader picked up a valid identity, the reader unlocked the door. Ultimately this advancement is soon t...
Have you ever been jamming to your favorite song on the radio and every swear they put a beep or some random word? For example, “Walk up to the club like, 'What up? I got a big (beep).' I'm so pumped about some (beep) from the thrift shop.” It tends to get very annoying. So the question is, should radio stations censor songs? Most parents will say yes. They do not want their children to hear those words. I have respect for these parents. Except, my opinion is different. I think radio stations should not censor songs but they should have warnings.
I have selected to listen to CBS (101.1) FM and WNYC (820) AM. CBS FM is considered to be a commercial radio station, were as WNYC is a public radio station. These are two entirely different radio stations, which I've selected to listen to for my assignment. In this essay, I will discuss the format of the stations, how they affect me personally, and the use of productions of each station.
The essay is a popular form for writers to express their ideas. It can be found in many sources: newspapers, magazines, and journals. The essay is no longer limited to these mediums, and as communication technology develops, the essay has extended into new arenas. What was once an exclusively paper-and-ink technology is now available over the airwaves and through the phone lines. The essay has found its way to new formats through the radio and internet. We were once readers, but have now become listeners and spectators through the cyberculture revolution.
In aviation, radar system used to detect aircraft, weather formations and terrain. Radar system uses radio waves to determine the range, altitude, direction and speed of objects. Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR) are installed in ground-based Air Traffic Control (ATC) radar system. PSR is a radar system that detects the positions of the aircraft within the control area and weather conditions. SSR is a radar system that detects the positions of the aircraft and receives additional information, for example, the aircraft's identity, altitude and distance. Both PSR and SSR antennas are co-located and work as an integral system. The Raytheon Airport Surveillance Radar (ASR-11) is a National Airspace System (NAS) certified ATC radar system and deployed worldwide to over 125 sites.
In modern society, radio is the most widely used medium of broadcasting and electronic communication. Radio can be broadcasted with both microwaves and longer radio waves. These are transmitted in two ways: amplitude modulation (AM) and frequency modulation (FM). Amplitude radio is created by combining a sound wave from a microphone, tape, record, or CD with a "carrier" radio wave. This results in a wave that transmits voice or programming as its amplitude (intensity) increases and decreases. Frequency modulation conveys information, voice, and music on a radio wave is to slightly change, or modulate, the frequency. One big advantage of frequency modulation is that it is static free.
The digital era arrives. Blue Book information editorial board and Social Science Literature Publishing House (2010) pointed out that “China's e-commerce transaction volume reached 3.85 trillion yuan in 2009”. Utilisation of e-business services was also high amongst Hong Kong people. About 98.3% of all persons had used e-business services such as Octopus Card and Automatic Teller Machine (Census and Statistics Department, 2009). One of the pitfalls for the development of e-business, however, is the concerns on consumer privacy. According to Green’s (1999) survey, 54% of respondents had decided not to purchase a product because of a concern on overuse of personal information collected in the e-business transaction. This essay examines the circumstance on protection of consumer privacy in e-business. As e-business is surging by astronomical number and consumer information is a kind of property, the protection of consumer privacy in e-business becomes significant. This essay begins with the causes of the problem, and then move on to analyse the effects. Lastly, the essay concludes with the solutions to the problem.

RADAR is a term is used to refer to electronic equipment that perceive the presence, course, altitude, and distance of objects by using reflected electromagnetic waves. The term radar is in fact an acronym made up of the words radio detection and ranging (RADAR = RAdio Detection And Ranging). The fundamental basics of RADAR is built upon electromagnetic radiation. RADAR utilises radio waves which is a type of electromagnetic wave on the electromagnetic spectrum. RADAR finds target objects by sending out radio waves that bounce off targets as a radio echo. These echoes are then measured to detect the distance between the target and the RADAR system. These radio waves are not affected by lack of visibility and also penetrates weather to
“He shoots!!! He scores!!!” these are famous words that Foster Hewitt made famous broadcasting a hockey game on the radio (“The Early Years”). It was words like these that the public became used to because there was no television. The radio served as the first medium to hear things live as they happened. This gave sport fans the opportunity to sit down and tune into a game anytime they like. The radio started off big and then took a dramatic fall due to the introduction of the television. However, radio found new ways to attract the public.
