Unemployment can pose particular problems for school leavers and other young people. Some English studies on the effects of unemployment are reviewed, and some of the causes and effects of unemployment among young people in Australia are then discussed. Some suggestions are made for areas in which further research could be carried out. 相似文献

Two potential problems in sex surveys—respondent refusalsand invalid reporting—are examined for national and areaprobability samples of males and females. Little support isfound for the contention that sexual topics constitute a sensitiveresearch area in terms of respondent cooperation and candor.It is found that (1) respondent cooperation, as indicated byrefusals and terminations, is neither more nor less problematicin sex research than in surveys on other topics; (2) respondentreports of sexual matters are not systematically related tointerviewer characteristics such as gender, sexual experience,or technical competence; (3) respondent candor, when self-reported,also is not associated systematically with either interviewercharacteristics or demographic and sexual characteristics ofrespondents. This analysis does identify, however, evidencethat (4) sexual matters often are sensitive topics for interviewersand principal investigators, leading both to interviewer turnoverand the creative construction of unobtrusive data collectionprocedures. 相似文献

In an experiment, thirty-six professional insurance men employed the utility method, the worry method, and the comparison method in two insurance problems to determine the appropriate insurance coverage. It was found that the best act with the utility method almost always was no insurance, whereas the best act with the other two methods tended to be complete insurance. The utility method best act rarely agreed with the subject's actual preferred act, while the comparison method best act usually was the same or almost the same as the actual preferred act. While the worry method suggests that the subjects typically are risk averse, the utility functions obtained tend to show that the subjects typically are not risk averse. 相似文献

In most econometrics courses the students are given limited exposure to the empirical applications of econometric theory. The use of canned programs would make it possible to cover more applied econometric work, and help prepare the students for more empirical work. The computer can be a valuable teaching aid for both instructor and student. The students will also gain valuable experience in the area of computer assisted data analysis. This paper discusses many of the programs appropriate for use in econometrics courses. Examples of problems using programs, and several alternative outlines of possible courses in applied econometrics are presented. 相似文献

The use of computers in teaching statistics can make an impact upon students in two ways. First, it can affect the amount and rate of learning of statistics. Second, it can affect student attitudes toward computers, statistics and quantitative methods. This note reports a study on the effects of the computer in teaching statistics on student attitudes. The data are based on pre- and post-course questionnaires administered in a first-year statistics sequence. The results partly confirm expectations, and partly raise questions for further investigation. 相似文献
