P. Christopher Earley Brian C. Perry 《Organizational behavior and human decision processes》1987,39(3)
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

Christopher J. Martin 《Argumentation》1987,1(4):419-436
Mediaeval logicians inherited from Boethius an account of conditional propositions and the syllogisms which may be constructed using them. In the following paper it is shown that there are considerable difficulties with Boethius' account which arise from his failure to understand the nature of compound propositions and in particular to provide for their negation. Boethius suggests that there are two different conditions which may be imposed for the truth of a conditional proposition but he really gives no adequate account of how such propositions may be obtained. The true greatness of Peter Abaelard as a philosophical logician is revealed in what he is able to do with the material which he found in Boethius. It is shown that he developed a precise theory of conditionals giving an account of how true conditionals may be obtained and principles which may be used to reject others as false. Unlike Boethius Abaelard properly appreciates that conjunctions must be treated as logical units. Even he, however, falls victim to difficulties which arise when this connective is brought into contact with negation and the conditions which he lays down for the truth of a conditional. 相似文献

Adolescent alcoholism in Benin City, Nigeria 总被引:1,自引:0,他引:1
O A Pela 《Adolescence》1986,21(82):487-492
The consumption of alcohol by Nigerian adolescents is investigated. Adolescence and alcoholism as applied in this study are defined, and the financial costs and physical and mental effects of alcohol use are described. The author used unobtrusive methods to gather data, visiting three nightclubs and an amusement park where alcohol is served in order to observe and interview adolescents. The findings show that adolescents begin drinking at an early age and consume large quantities of beer. The findings are consistent with those of other epidemiological studies. Finally, recommendations for controlling adolescent alcohol use are made. 相似文献
