A questionnaire was administered to 142 mate students who were enrolled in ROTC and 18 male students who had dropped out of ROTC. Several months later seven of the above 142 subjects dropped out of ROTC. A ratio expectancy theory model was developed from the questionnaire as an operational definition of motivation to remain in ROTC. The results indicated that the 25 dropouts had a significantly lower (p < .001) score on this motivational measure than the 135 subjects who were still enrolled in ROTC, and also that these latter subjects were as strongly attracted to a civilian job as they were to an Army job. The implications of these findings relative to the ability of the Army to attract career officers were discussed.  相似文献

The Job Attitude Scale was administered to majors and captains and to upper-middle managers and lower-middle managers of industrial organizations. No significant differences in general intrinsic orientation were found between the majors and the upper-middle managers, or between the captains and the lower-middle managers. The majors and the upper-middle managers were significantly more intrinsically oriented than the captains and the lower-middle managers. The results also showed that the military samples were significantly more concerned with advancement, security, status, and family needs-salarywise-than the civilian samples, while the two civilian groups were significantly more concerned with achievement, supervision, and relations with subordinates than the two military groups. The results were discussed in view of job environment and job level.  相似文献

The purpose of this study was to examine a model for investigating employee mental health in industrial environments and, more particularly, to determine the extent to which a worker's perceptions of the environment covaried with mental health criteria. The managerial segments of two divisions of a 35,000 employee company were represented in this study. In general, it was found that employees who perceived the environment as having clarity in the organizational structures, little administrative interference in work processes, equitable reward systems, and trust and consideration for employees tended to have more favorable scores on mental health indices. Also, some differences between the two work environments, as well as between male and female employees, were noted and discussed.  相似文献

This study was designed to identify the important clusters of occupational groups identifiable from an analysis of the dimensions accounting for similarity in profile shapes among a set of 28 new vocational interest measures. A total of over 47,000 individuals belonging to 189 particular occupational groups have completed the Strong Vocational Interest Blank and had their data summarized in the form of group profiles. The matrix of 189 occupational group profiles of the 22 SVIB Basic Scales was analyzed by a series of multivariate procedures designed to predict group profiles on the Jackson Vocational Interest Survey (JVIS). Predicted JVIS profiles were obtained using an intercorrelation matrix of 548 males who had completed both the SVIB and the JVIS. Predicted JVIS profiles were subjected to a form of transpose factor analysis to obtain clusters of similar occupations. A total of 23 distinct occupational clusters were obtained, ranging from military officers to salesmen, and were interpreted as representing the major groupings of occupations defined by similar patterns of vocational interest.  相似文献

This study was designed to investigate experimentally the effectiveness of the Vocational Exploration Group in assisting students to become more aware of the world of work and its relevance for them. Sixty male, Mexican-American, junior high students were randomly assigned to one of three groups: (1) Vocational Exploration Group, (2) VEG without interaction, or (3) Control. Upon completion of treatments subjects were post-tested with an instrument designed to assess knowledge of factors such as differing functions of jobs, interests and skills needed in different jobs and satisfactions available from work. Analyses revealed no statistically significant differences (a = .05) among groups.  相似文献

The study evaluates a test of occupational information administered to a national sample of 5000 young men, aged 14–24 in 1966, as part of the National Longitudinal Surveys of employment behavior. The predictive validity of the test score is assessed by reference to multiple regression analyses which confirm the significance of the score as an independent predictor of subsequent hourly earnings and occupational status. Correlation and factor analyses are used to examine the quality of the measurement instrument. All in all, the instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of difficulty. The test's reliability compares favorably with a commercially produced test designed to be used in counseling as a measure of occupational knowledge. With the possible modification of deleting a section relating to knowledge of earnings differentials, the test is commended to those involved in assessing and counseling the occupational choice process.  相似文献

Vocational indecision was defined as being both a college upperclassman and having no major. In a sample of 1622 students in college for three years, 24% indecisive students were found and compared with vocationally decisive students (having majors) using precollege measures of achievement, aptitude, and interest. Measures of interest differentiation were of particular concern. Indecisiveness was best predicted from present and past achievement measures, e.g., cumulative college GPA or high school mathematics GPA. Interest predictors slightly augmented the multiple correlation including Outdoor interest, Business Contact interest, and interest differentiation. Most important to vocational indecision in these juniors and seniors, however, was lower academic achievement.  相似文献

The psychological meaning and predictive value of a person's vocational aspirations were examined by applying Holland's typology to the vocational aspirations of high school juniors (N = 1005), college juniors (N = 692), employed adults (N = 140), and a second sample of college students studied over a one-year interval (N = 624). The aspirational data were obtained from the Daydreams section of the Self-Directed Search (Holland, 1972). Categorical and correlational analyses show that a person's retrospective vocational aspirations have coherence and yield efficient predictions of subsequently expressed choice. In addition, the degree of coherence or similarity among a person's vocational aspirations provides a potentially useful index of a person's decision-making ability.  相似文献
