Designed to measure differences in employment issues between a selected native Canadian Indian group and a non-native comparison group in Toronto, the study demonstrated that given similar circumstances for comparison, Native Canadians are less formally educated and skill trained than are non-natives of comparable age, sex, and education. Respondents under the age of 25 and over 50 earned substantially less than respondents within that age range.  相似文献

Research examined both the Position Analysis Questionnaire (PAQ) and the possible analyst sources for gathering job analysis information. 25 state government jobs were examined using job incumbents, supervisors, job analysts, and a comparison group of college students. Reliability and validity (judge convergence and prediction of present pay levels) information was determined for each of the four analyst categories. Results indicate that there is little difference between analyst sources, including students, in terms of their ability to reliably analyze a job using the PAQ. Convergent validity results showed a high degree of agreement among all judge categories when summing item frequencies across all 25 jobs. The prediction of present pay levels was significant for all judge categories but was noticeably smaller than previously reported studies. This seemed to be primarily due to the restriction in salary range of the present study. An analysis of judge response bias showed that supervisors and incumbents rate all or most PAQ items higher than their analyst counterparts. These findings suggest that who furnishes responses to a job analysis inventory makes little practical difference. The exception is that the determination of pay levels and human requirements for test construction purposes should be viewed with caution when different analyst sources are utilized for different jobs.  相似文献

Multiple scenario analysis is used by many organizations for long-term planning, in part because the development of more than one scenario of the future is thought to prevent overconfidence in any one specific forecast. The present study attempts to clarify some of the questions concerning the cognitive effects of scenario presentation by distinguishing between confidence and subjective uncertainty. It examined the impact of different types of scenario information on confidence ratings, credible intervals, and features of forecast series. Subjects (N=186) read either one, two, or no scenario(s) describing potential changes in the level of a stimulus variable, then made forecasts of that variable over the next fifty years. Reading any type of scenario information increased confidence in forecasts; there was no reduction in confidence due to presentation of multiple conflicting scenarios, compared to presentation of only one scenario. Differences in number and in type of scenarios presented did, however, affect subjective uncertainty.  相似文献

A novel single-attribute test between competing expectancy-value models of attitude was devised using subjects' ratings of clusters of statements located at a range of points within a three-dimensional semantic space with expectancy, value and attitude as the co-ordinates. The data provided strongest support for a model using bipolar scoring for evaluation and unipolar scoring for expectancy.  相似文献

The changing profile of drug use has highlighted the need for age-appropriate education which requires insight into children's representations of drugs. Representations were elicited from 134 children aged between 5 and 11 years, drawn from two schools, by asking them to draw and write their responses to questions relating to a story about losing and finding a bag of drugs. Relevant responses were generated by 119 children aged between 8 and 11 years. A content analysis of these responses revealed differences with school and age. Older children were more likely to recognize that drugs can be good or bad depending on type, quantity taken and reason for use. The children had firm ideas about who takes drugs and their motivations and were knowledgeable about methods of use. They recognized that drugs can be dangerous, but had little understanding of how or why. The children's representations were characterized by fear and uncertainty and most wanted to know more. These findings are used to argue that there is a need for child-centred constructivist approaches to drug education which seek to demystify drugs and drug use and to orientate children to the realities of the world of drugs in the 1990s.  相似文献
