Gender Gap
The girls in this sixth grade class in East Palo Alto, California, all have the same access to computers as boys. But researchers say, by the time they get to high school, they are victims of what the researchers call a major new gender (性别) gap in technology. Janice Weinman of the American Association of University Women says, "Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information."＜br＞
After re-examining a thousand studies, the American Association of University Women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom.＜br＞
An instructor of a computer lab says he&39;s already noticed some differences. Charles Cheadle of Cesar Chavez School says, "Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow."＜br＞
Six years ago, the software company Purple Moon noticed that girls&39; computer usage was falling behind boys. Karen Gould says, "The number one reason girls told us they don&39;t like computer games is not that they&39;re too violent, or too competitive. Girls just said they&39;re incredibly boring."＜br＞
Purple Moon says it found what girls want, characters they can relate to and story lines relative to what&39;s going on in their own lives. Karen Gould of Purple Moon Software says, "What we definitely found from girls is that there is no intrinsic (固有的 ) reason why they wouldn&39;t want to play on a computer; it was just a content thing."＜br＞
The sponsor of the study says it all boils down to this: the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21 st century.
According to the passage， girls are victims of the gender gap in technology because__________. 查看材料
A.they can not discover new ways to use computers
B.they have the same access to computers as boys
C.they are likely to be less comfortable with computers
D.they can only use computers for word processing
In conducting research on cultural and ethnic minority issues, investigators distinguish between the emic approach and the etic approach. In the emic approach, the goal is to describe behavior. in one culture or ethnic group in term that are meaningful and important to the people in that culture or ethnic group, without regard to other cultures or ethnic groups. In the etic approach, the goal is to describe behavior. so that generalizations can be made across cultures. If researchers construct a questionnaire in an emic fashion, their concern is only that the questions are meaningful to the particular culture or ethnic group being studied. If, however, the researchers construct a questionnaire in an etic fashion, they want to include questions that reflect concepts familiar to all cultures involved.
How might the emic and etic approaches be reflected in the study of family processes？ In the emic approach, the researchers might choose to focus only on middle-class White families, without regard to whether the information obtained in the study can be generalized or is appropriate for ethnic minority groups. In a subsequent study, the researchers may decide to adopt an etic approach by studying not only middle-class White families, but also lower-income White families, Black American families, Spanish American families, and Asian American families. In studying ethnic minority families, the researchers would likely discover that the extended family is more frequently a support system in ethnic minority families than in White American families. If so, the emic approach would reveal a more different pattern of family interaction than would the etic approach, documenting that research with middle class White families cannot always be generalized to all ethnic groups.
According to the first paragraph, researchers unfamiliar with the target cultures are inclined to
A．be overcautious in constructing meaningful measures
B．view them from their own cultural perspective
C．guard against interference from their own culture
D．accept readily what is alien to their own culture
This phenomenon came to be known as the Hawthorne effect since the experiments were conducted at the Western Electric Hawthorne Plant. This was the first documented and widely published evidence of the psychological effects on doing work, and it led to the first serious effort aimed at examining psychological and social factors in the workplace. Further experiments were continued for five years. Generally, the researchers concluded from their experiments that economic motivation (pay) was not the sole source of productivity and, in some cases, not even the most important source. Through interviews and test results, the researchers focused on the effects of work attitudes, supervision, and the peer group and other social forces, on productivity.
Their findings laid the groundwork for modem motivation theory, and the study of human factors on the job, which continues to this day in such common practices as selection and training, establishing favorable work conditions, counseling, and personnel operations. The contributions of this experiment shifted the focus of human motivation from economics to a multifaceted approach including psychological and social forces.
What is the passage primarily about？
A．The first widely published development in modem motivation theory.
B．Shifting the focus of human motivation from economics to a multifaceted approach.
C．The importance of careful research.
D．The results of a pioneering study at Western Electric.
听力原文：M: Did you watch undersea Discover), last night？
W: No, I missed it. Did you？
M: Yeah, it was pretty good...It was about barnacles.
W: Hmm.
M: You know how they stick themselves to stuff in the ocean ... like rocks or boats？
W: Uh—huh.
M: Well, they do that when they're young, and then they stay in the same place forever.
W: It figures. Have you ever tried removing one of those things. Last summer I tried to scrape some off a pier...I had to give up after a while. You'd think they wouldn't be able to stick like that undcrwater.
M: That's one. reason scientists are-trying to figure out what their glue's made of. It's one of the strongest adhesive in nature, and it's a natural protein, so it probably wouldn't be harmful like some synthetic glues.
W: Really？
M: Yes. these biomedical researchers were talking about its possible uses. Orthopedists could use it for mending broken bones; or it could be used in dentistry.
W: I wish I'd seen that.
(23)
A．The reproductive cycle of barnacles.
B．A new source of protein.
C．Types of sea animals.
D．The adhesive quality of barnacles.
2 The assumption underlying this distinction is that subjective or emotional criteria do not maximize utility or satisfaction. However, it is reasonable to assume that consumers always attempt to select alternatives that, in their view, are to maximize satisfaction. Obviously, the assessment of satisfaction is a very personal process, based upon the individual's own need structure as well as on past behavioral, social, and learning experiences. What may appear as irrational to an outside observer may be perfectly rational within the context of the consumer's own psychological field. For example, a product purchased to enhance one's self-image (such as a fragrance) is a perfectly rational form. of consumer behavior. If the behavior. did not appear rational to the person who undertakes it at the time that it is undertaken, obviously he or she would not do it. Therefore the distinction between rational and emotional motives does not appear to be warranted.
3 Indeed, some researchers go so far as to suggest that emphasis on "needs" obscures the rational, or conscious, nature of most consumer motivation. They claim that consumers act consciously to maximize their gains and minimize their losses; that they act not from subconscious drives but from rational preferences, or what they perceive to be in their own best interests.
4 Marketers who agree with this view are reluctant to spend either time or money to uncover subconscious buyer motives. Instead, they try to identify problems that consumers experience with products then on the market. For example, instead of trying to identify any special needs that consumers may have for dog food, the marketer will try to discover any problems that consumers are experiencing with existing brands of dog food. If the marketer discovers that many dog foods leave an unpleasant odor in the refrigerator, he or she can develop a new product that solves this consumer problem and then run advertisements that announce to dog owners that the new product does not impart unpleasant odors. Thus, rather than address consumers' expressed needs, such marketers attempt to discover and solve consumers' problems and thereby achieve market success.
According to the classification of consumer motives, ___________ should belong to the category of emotional motives.
A．color
B．durability
C．fashion
D．service
