《古兰经》的伦理道德思想(续)

三、敬畏 敬畏是一种宗教美德,《古兰经》用它来确定人与人、人与造物主之间的关系。“敬畏”一词及其派生词大都出现在《古兰经》中有关道德和社会主张的经文中。所谓“敬畏”就是要人类谨防那些使真主恼怒和损人害己的行为。因为“敬畏”一词本意为保护自己。人之所以保护自己,是因有可惧怕的东西存在。安拉是最值得惧怕的,所以因安拉而保护自己是特别重要的。既然惧怕,就

七、公正 伊斯兰教的理想之一就是责成其信徒要丢掉一切与自身利害有关的考虑,主持人间公道。安拉说:“信教的人们!你们应主持公正,应为安拉而作见证,即使不利于自身,或自己的父母和亲属。不论被见证者是富人或贫人,那安拉是最宜于对付他们的。你们不要徇私,以免偏离公正;如果你们歪曲事实,或拒绝作证,那安拉对你们的作为将是一清二楚。”(4:135)     

Participation by women in behavior analysis

The participation of women in behavior analysis as authors of articles published in the Journal of the Experimental Analysis of Behavior (JEAB) and the Journal of Applied Behavior Analysis (JABA), as members of the Association for Behavior Analysis (ABA), and as contributors to the 1982 ABA convention was examined. Since the inception of JEAB and JABA, men have appeared as authors far more frequently than women, although women have published relatively more frequently in the latter journal than in the former. Across years, there has been an upward trend in the proportion of JEAB authors who are female; this is not the case for all JABA authors, although it does hold for senior authors. In 1980-1981 and 1981-1982, females represented approximately half of ABA's student and affiliate members but less than a third of its full members. Approximately a third of the contributors to posters and symposia and a seventh of those delivering invited addresses at the 1982 ABA convention were women.     

Choice, changeover, and travel: A quantitative model

Six pigeons were trained on concurrent variable-interval schedules in which responding on fixed-interval schedules was required to give access to the alternate schedule. Responding on the concurrent schedules was not allowed, after changing over had commenced, until the changeover schedule had been completed. In Parts 1 to 3 of the experiment, the changeover fixed-interval schedules were equal and were 0 s, 10 s, and 20 s, respectively. In each part, the relative frequency of reinforcement obtained on the concurrent schedules was varied over at least five conditions. In Part 4, the concurrent schedules were equal, and one changeover fixed-interval schedule was twice the other. Under these conditions, the absolute sizes of the changeover schedules were varied. Increasing the changeover requirement from 0 s to 10 s (Parts 1 and 2) resulted in increases in the sensitivity of behavior allocation to reinforcers obtained, but no further increase was obtained when the changeover schedules were increased to 20 s (Part 3). In Part 4, performance was biased towards the concurrent schedule that took less time to enter. These results are consistent with a subtractive punishment model of travel in which the degree of punishment is measured by the number of reinforcers apparently lost from a schedule when the subject changes to that schedule. Absolute times spent on the main keys could be accurately described by a previous model of changeover performance.     

Violations of stochastic transitivity on concurrent chains: Implications for theories of choice

The concurrent-chains procedure has been used to measure how choice depends on various aspects of reinforcement, such as its delay and its magnitude. Navarick and Fantino (1972, 1974, 1975) have found that choice in this procedure can violate the condition of stochastic transitivity that is required if a unidimensional scale for reinforcements is to be possible. It is shown in this paper that two simple unidimensional models of choice on concurrent chains can produce violations of stochastic transitivity. It is argued that such violations may result from the complex contingencies of the concurrent-chains procedure.     

Concurrent schedules: Effects of time- and response-allocation constraints

Five pigeons were trained on concurrent variable-interval schedules arranged on two keys. In Part 1 of the experiment, the subjects responded under no constraints, and the ratios of reinforcers obtainable were varied over five levels. In Part 2, the conditions of the experiment were changed such that the time spent responding on the left key before a subsequent changeover to the right key determined the minimum time that must be spent responding on the right key before a changeover to the left key could occur. When the left key provided a higher reinforcer rate than the right key, this procedure ensured that the time allocated to the two keys was approximately equal. The data showed that such a time-allocation constraint only marginally constrained response allocation. In Part 3, the numbers of responses emitted on the left key before a changeover to the right key determined the minimum number of responses that had to be emitted on the right key before a changeover to the left key could occur. This response constraint completely constrained time allocation. These data are consistent with the view that response allocation is a fundamental process (and time allocation a derivative process), or that response and time allocation are independently controlled, in concurrent-schedule performance.     

Attribution of control and teenage pregnancy

In rural Appalachia in Tennessee, data on 13 female adolescents who had experienced a pregnancy (mean age=16 years, 7 months) were compared with those on 38 female adolescents who had not experienced a pregnancy (mean age-16 years, 4 months) to test the hypothesis that teenagers who experience a pregnancy have external attributions of control over their life events. The Nowicki-Strickland Locus of Control Scale for Children was administered to determine their beliefs about causes of events in their lives. All the girls were white and matched for socioeconomic status, housing, and cultural background. The mean attribution of control to external agents score stood at 14.5 for girls who had experienced a pregnancy compared with 12.7 for those who had not experienced a pregnancy, but the difference was not significant (p=.08).54% of the cases exhibited external attributional orientation compared with 16% of the controls (p.02). This finding concurred with that of earlier studies. The fact that not all the girls who had experienced a pregnancy had external attributional orientation suggested that it is not the only factor linked to adolescent pregnancy. Studies have not identified whether external attributional orientation is a causal factor or consequence of adolescent pregnancy. A 1980 study found that women who had shown more external locus of control scores during pregnancy and tended to castigate themselves had a high probability of postpartum depression. Another study indicated that rises in depression among adolescents were linked to prechange orientations toward external attributions of control. Practitioners should selectively pay attention to teenagers who have extreme attributional orientations since many teenagers carry their pregnancies to term and choose to rear their infants. These orientations appear to pose risks for the adolescent mother and her children.
