At the work site, smoking accounts for increased health care expenses and worker absenteeism due to smoking-related illness and reduced productivity and lost wages. Developing comprehensive and accessible smoking cessation programs at the work site is an important objective for health care professionals. In this study, employees of 43 corporations participated in a televised smoking cessation program accompanied by self-help manuals. The media component involved presenting a smoking cessation program on a network television affiliate station during the 4:30 p.m. and 10:00 p.m. news for 20 days. Employees at half the corporations also had access to semiweekly self-help group meetings. Adding self-help support groups to a program involving self-help manuals and the media reports was found to significantly increase abstinence and its maintenance over time. The implications of using the media, self-help groups, and work site locations in large-scale community-based interventions are discussed. 相似文献

The relation of task strategy planning to task performance was explored using a series of laboratory investigations. The first study examined the influence of providing a subject a work strategy and a specific work goal on his or her subsequent performance. A total of 72 subjects participated in a 2 (goal) × 2 (task strategy priming) × 3 (performance period) × 3 (task type) repeated measures, factorial design study. The results demonstrate that task strategy priming and goal setting increase the amount of an individual's planning and directs the type of plan developed. A second study was conducted (n = 90) to further explore the effect of task strategy priming on planning and performance. Taken together, the results of the studies demonstrate that (a) goal setting increases strategic planning, (b) priming influences the amount and type of planning engaged in by an individual, and (c) task performance varies as the result of the type of plan an individual develops. The results are discussed as a means of expanding the use of cognitive constructs in theories of work motivation. 相似文献

Effective overall performance in judgment tasks generally involves both acquisition of information and integration of the information acquired. When information is costly the decision maker must balance acquisition costs against improved decisional accuracy, a complex balancing problem in which, laboratory evidence suggests, humans often do poorly. The three experiments reported here extend this earlier evidence to different task structures, subject pools, incentive systems, information volumes, decision aids, and kind of data sources. Though each of these factors was found to affect performance, the general finding was of persistent underpurchase (buying less information overall than is optimal) and mispurchase (buying poor sources when better sources are available at the same cost), with significant inflation of overall costs. It is proposed that unaided human judgment is unequal to the complexity of the cost/benefit trade-offs involved in acquiring costly information, and that formal decision analysis should be preferred whenever the stakes justify. 相似文献

The impact of pre-employment integrity testing on employee turnover and inventory shrinkage losses 总被引:1,自引:0,他引:1

A major home improvement chain located primarily in the western United States initiated the use of thePersonnel Selection Inventory, a written integrity test, as part of its pre-employment hiring process. For two years only, those job applicants who passed this test and other pre-employment criteria were hired by the chain. Following the introduction of the inventory, there was: (1) a 50% reduction in the number of employee terminations for theft, illegal drug use, and violence over a five year period and (2) a savings in shrinkage losses that amounted to over two million dollars over a two year period. 相似文献

In the past decade, encounter groups have become a widely recognised technique of intervention for counsellors. Empirical research on encounter groups is confusing. Trends in research are obscured by a diversity of definitions, methodologies and subjects. This review considers the most significant research on the effectiveness of encounter groups, focusing on positive and negative effects, leader behaviour, group characteristics, participant characteristics, and the maintenance of change. Conclusions are drawn relating the research to practice, with some suggested guidelines for use of encounter groups in counselling interventions. 相似文献

This report describes the methods used to improve the performance of a three-dimensional movement-tracking system that is based on infrared cameras and light-emitting diodes. The technique has general application to similar systems with other types of cameras. The improvement was obtained by postprocessing to correct camera-image distortions. This procedure yielded a six-fold increase in accuracy. With a 900-mm-cube viewing volume, the error in locating a point was reduced to less than 3 mm. 相似文献

This study investigated the intellectual functioning and personality characteristics of 81 Australian ex-servicemen, 42 of whom had served in Vietnam. A Cognitive Impairment Model (SCIM) developed by Savage (1978, 1981, 1984) enabled intellectual functioning levels, intellectual deterioration and learning ability in the verbal and performance modalities to be asses. The Clinical Analysis Questionnaire (CAQ) of Krug (1980) based 00 Cattell's theory and personality measurement techniques provided an assessment of normal personality characteristics and clinical factors. The data suggested that the two groups, Australian ex-servicemen and Australian Vietnam veterans, were relatively homogeneous with regard to cognitive functioning and gave no indication of impairment in their intellectual levels or of their learning ability. Significant personality differences were, however, found between the two groups of ex-servicemen. The Vietnam veterans showed significantly more tension, depression, guilt, resentment, alienation and hypochondriasis than their colleagues who had remained in Australia. They were more withdrawn from others and from reality and had more abnormal thought than the ex-servicemen who had not been to Vietnam. The cognitive data do not support the view that Vietnam veterans suffered from any serious cognitive impairment. The personality data, however, suggest a significant “Psycbological Stress Syndrome” in these Vietnam veterans which required professional psychological treatment. 相似文献

This study tests the hypothesis that children's deficiency in encoding itemspecific and relational information in episodic events contributes to age differences in recall and recognition. In two experiments, grade school children and college adults were presented with word triplets varying in categorical relatedness. The processing of the item-specific and relational information in the triplets was independently manipulated. Experiment 1 assessed cued recall, and Experiment 2 assessed recognition of both the central target and incidental contextual members of each triplet. The results showed that the processing manipulations had independent and different effects on recall and recognition, on memory for the members of the different kinds of triplets, on the use of the retrieval cues, and on memory for target and incidental words. Developmental differences were found in both recall and recognition, and of both target and incidental words, that varied with triplet type and the processing manipulations and that were attributable to differences in the encoding of item-specific and relational information in the triplets. The discussion contrasts alternative accounts of children's encoding deficiency, and suggests that the distinction between automatic, age-invariant, and strategic age-sensitive encoding processes needs to be redrawn. 相似文献

A self-attention approach to the effect of the group on the individual is applied to the phenomenon of participation in religious groups. Previous work indicates that group members become more self-attentive, and thus more concerned with matching to standards of appropriate behavior, as the relative size of their subgroup decreases. This suggests that, in the context of religious groups, members of a congregation will be more self-attentive, and thus more likely to participate in the religious group, when there are fewer congregation members relative to the number of ministers. The results of analysis of ten archival records of participation in religious groups support this perspective. The importance of self-attention processes in religious group settings is discussed. 相似文献
