There is little question that substantial labor-market differences exist between men and women.Among the most researched difference is the male-female wage gap. Many different theories aroused to explain why men earn more than women. One possible reason is based on the limited geographical mobility of married women [Robert Frank, 1978]. Family mobility is a joint decision in which the needs of the husband and wife are balanced to maximize family welfare. Job-motivated relocations are generally made to benefit the primary earner in the family. This leads to a constrained job search for the secondary earner, as he or she must search for a job in a limited geographic areA、Since the husband is still the primary wage earner in many families, the job search of the wife may suffer. Individuals who are tied to a certain area are labeled "tied-stayers," while secondary earners, who move for the benefit of the family are labeled "tied-movers" [Jacob ~Mincer, 1978]. The wages of a tied-stayer or tied-mover may not be substantially lower if the family lives in or moves to a large city. If a large labor market has more vacancies, the wife may locate a wage offer near the maximum she would find with a nation-wide search. However, being a tied- stayer or tied-mover can lower the wife’s wage if the family lives in or moves to a small community.A、small labor market will reduce the likelihood of her finding a job that utilizes her skills,As a result she may accept a job for which she is overqualified and thus earn a lower wage. This hypothesized relationship between the likelihood "of being overqualified" and SMSA、size is termed "differential overqualification." Frank 1978 and Haim Ofek and Yesook Merrill [1994] provide support for the theory of differential overqualification by finding that the male-female wage gap is grater in smaller SMSA’s. While the results are consistent with the existence of differential overqualification, they may also result from other situations as well. Firms in small labor markets may use their monopsony power to keep wages down. Local demand shocks are found to be a major source of wage variation both across and within local labor markets [ Robert Topel, 1986]. Since large labor markets are generally more diversified, a demand shock can have a substantial impact on immobile workers in small labor markets.Another reason for examining differential overqualification involves the assumption that there are more vacancies in large labor markets. While there is little doubt that more vacancies exist in large labor markets, there are also likely to be more people searching for jobs in large labor markets, if the greater number of vacancies is offset by the larger number of searchers, it is unclear whether women will be more likely to be overqualified in small labor markets. Instead of relying on wages to determine if differential overqualifieation exists, we consider an explicit form of overqualifieation based on education. |

The range in frequencies of musical sounds is approximately 20- 20,000 cycles per second (cy/sec), Some people can hear higher frequencies than others. Longitudinal waves whose frequencies are higher than those within the audible range are called ultrasonic frequencies. Ultrasonic frequencies are used in sonar for such purposes as submarine detection and depth finding. Ultrasonic frequencies are also being tried for sterilizing food since these frequencies kill some bacteriA、Sound waves of all frequencies in the audible range travel at the same speed in the same medium. In the audible range, the higher the frequency of the sound the higher is the pitch. The term supersonic refers to speed greater than sounD、An airplane traveling at supersonic speed is moving at a speed greater than the speed of sound in air at that temperature. Mach 1 means a speed equal to that of sounD、Mach 2 means a speed equal to twice that of sound, etC、 Musical sounds have three basic characteristics; pitch, loudness, and quality or timbre.As was indicated above, pitch is determined largely by the frequency of the wave reaching the ear. The higher the frequency the higher is the pitch. Loudness depends on the amplitude of the wave reaching the ear. For a given frequency, the greater the amplitude of the wave the louder the sounD、To discuss quality of sound we need to clarify the concept of overtones. Sounds are produced by vibrating objects. If these objects are given a gentle push, they usually vibrate at one definite frequency producing a pure tone. This is the way a tuning fork is usually useD、When objects vibrate freely after a force is momentarily applied, they are said to produce their natural frequency. Some objects, like strings and air columns, can vibrate naturally at more than one frequency at a time. The lowest frequency which an object can produce when vibrating freely is known as the object’s fundamental frequency. Other frequencies that the object can produce are known as its overtones. The quality of a sound depends on the number and relative amplitude of the overtones present in the wave reaching the ear. |

Everything in today’s world is going faster and faster, and television commercials are no exception.At the start of the television age the standard commercial lasted 60 seconds, but most of today’s commercials are only half that length and many are even shorter. The 15-second commercial, introduced a few years ago as a way to cut skyrocketing advertising costs, may soon be the most common in the United States. (Our television-watching counterparts in Japan andEurope are already being treated to 7-second mini-commercials ! ) What stands behind the message that blips onto and off our television screens before we have time to get to the kitchen and hack Months of planning; hundreds of interviews with potential users of the product; hours of writing; dozens of actors, directors, and technicians; days of filming; and hundreds of thousands of dollm’s in payments to the television networks that will run the aD、 Take for example a recent commercial for a certain brand of cough drops. The manufacturer of the cough drops spent four months trying to think of a way to boost sales.After several surveys of cough drop users, the company decided to market a strawberry-flavored lozenge. Further surveys identified tile typical users of the strawberry-flavored cough drop as persons between the ages of 15 and 30. This infforination was important in planning the content and style of the commercial (fast-paced and upbeat, with colorful graphics and lively music) and in determining when to air it (during situation comedies, prime-time dramas, and music specials). The creative team at the advertising agency that handled the cough drop company’s account then took over.After hours of discussion and writing, they came up with six scripts, from which the client chose two. One involved a young woman pulling a strawberry out of a box of cough drops. The outline, or storyboard, for the commercial looked deceptively simple: four sketches and a few lines of ’voice-over.’ Yet these few words and images (just enough to fill 15 seconds) had been carefully selected to convey crucial information about the product: its effectiveness in suppressing coughs and soothing sore throats, the absence of sugar, and its strawberry flavor. Turning this carefully calculated script into an effective commercial involved finding just the right actor: a young woman who would be attractive to the target audience and who could make her positive response to the cough drops look convincing. Forty-two actors were. auditioned; one was chosen. The actor wasn’t the only element of the commercial that had to go through an audition. More than a hundred outfits were inspected before one was chosen for her to wear, and hundreds of strawberries had to be sorted through. The filming began at 9:30 one morning. "All" the actor had to do was to open a box of cough drops, pull out a strawberry and munch on it. Yet her movements and facial expressions had to be just right, and achieving that perfection took three hours and 72 shootings, or ’takes.’ Even then—shooting completed—the job was far from done. Thousands of feet of film had to be reduced to a compact 45 feet of finished commercial. Using million-dollar, computerized equipment, the producer, writer, and art director selected the best two takes and mixed images and sound to produce a polished final product. The resultA、simple, effortless-looking lisle film that shows none of the tremendous effort that went into producing it, but which should justify all of that time, creativity, and expense by boosting cough drop sales. |
