This paper presents the results of an empirical study measuring Muslim and Christian students' attitudes towards each other. The survey sample consisted of 300 students studying at Bethlehem University. A questionnaire was designed to elicit the respondents' amount of agreement with a series of assertions. Each statement was answered on a 5‐point Likert scale. The results indicate that the respondents have highly positive attitudes towards each other. The personal factors of age, place of residence, and religion do not have a very significant effect.  相似文献

The current study tested Freud's (1905/1960)theory that sexist humor may be associated withhostility toward women and extended previous researchshowing a link between hostile humor and aggression.Colleges students (N = 399 — approximately 92%white, 5% African American, and 3% other minorities)rated 10 sexist jokes on their perceived funniness.Results showed that the enjoyment of sexist humor waspositively correlated with rape-related attitudes andbeliefs, the self-reported likelihood of forcing sex,and psychological, physical, and sexual aggression inmen. For women, the enjoyment of sexist humor was only positively correlated with Adversarial SexualBeliefs and Acceptance of Interpersonal Violence. Womenalso found the jokes to be less enjoyable, lessacceptable, and more offensive than the men, but they were not significantly less likely to tell thejokes.  相似文献

A variable interval (VI) schedule is described that automatically adjusts the programmed rates of reinforcement in accordance with the rates of responding of subjects during the two immediately preceding 30-sec time intervals. The schedule prescribes that as rate of responding decreases, programmed reinforcement rate increases, and that when rate of responding increases, reinforcement rate decreases. Thus, programmed reinforcement rate is adjusted continuously until some target value is reached. Ten rats were exposed to this procedure five times a day at 1-h intervals. The target, set at VI 120 sec, was reached by most subjects within 4 days of training. Subsequently, all subjects responded consistently during five daily 1-h sessions with VI 120 sec. This procedure speeds up the training of subjects on long VI schedules and substantially reduces the time and effort spent observing the subjects and adjusting the schedule parameter value during the early development of responding.  相似文献

Considerable scientific evidence demonstrates the reduction in risk for neural tube defects (NTDs) associated with maternal preconceptional folic acid supplementation. The National Society of Genetic Counselors (NSGC) endorses the U.S. Public Health Service recommendations for folic acid supplementation at the 0.4 mg level for women in the general population and at the 4.0 mg level for women at high or increased risk for NTD pregnancies for at least 4 weeks prior to active pursuit of conception. We encourage targeted educational efforts and surveillance to assess results of this dietary supplementation. The NSGC further urges the Food and Drug Administration to fortify staple foodstuffs with folic acid for a population-based approach to minimize the number of NTD births.  相似文献

Directional judgments are typically slower when relative location is described by the words “east” and “west” or “right” and “left” than when described by the words “north” and “south” or “up” and “down.” A series of experiments are reported that disentangle verbal from perceptual encoding explanations for right-left difficulty. Overall, our results support a verbal encoding explanation for right-left confusion in the adult. Experiments 1-3 demonstrate that in a response-differentiation task, it is response to the labels “north,” “east,” “south,” and “west” that is responsible for right-left confusion. In addition, Experiments 4-6 demonstrate that right-left difficulty in a mirror image discrimination task is contingent on the use of directional labels. (The data also suggest that it may be more difficult to deal with “up,” “down,” “left,” and “right” than with “north,” “south,” “east,” and “west”) The data are interpreted as inconsistent with a bilateral symmetry explanation for right-left confusion.  相似文献

The purpose of the research was to identify empirically and measurably those dimensions considered important by laity in evaluating their priest. The 83-item questionnaire was developed from existing instruments and from an interview survey carried out on laity from a national selection of Episcopal parishes. 221 parishes responded with complete data. A factor analysis was performed on the data yielding eight useable factors: (a) Pastoral sensitivity, (b) Administrative Skills, (c) Scholarship, (d) Personal Integrity, (e) Innovation, (f) Personal Spirituality, (g) Meaningfulness of Services, and (h) Laity Involvement. The results of the research were seen as a beginning insight into what the laity perceived as important aspects of their parish priest's role, and an instrument to measure these dimensions for further research was produced.  相似文献

Based on an attributional analysis of menstrual distress, the present study examined how a woman is evaluated when she attributes an instance of negative social behavior to the approach or onset of menstruation. College men and women were asked to imagine an interaction in which a woman behaves very irritably and then gives one of several excuses for her negative behavior, two of which were menstrual related. Subjects evaluated each excuse in terms of (1) degree of annoyance, (2) blameworthiness, and (3) internality versus externality. The results showed consistent relationships between these evaluations and both sex of subject and general attitudes about menstruation. Males tended to see menstrual-related excuses as less blameworthy and more external than did females. In addition, general attitudes regarding the debilitating effects of menstruation predicted greater tolerance toward the use of menstrual excuses. These results are discussed in terms of their implications for the socialization and continuing reinforcement of menstrual distress.The research reported in this article was supported by grants SOC-7602137 and SOC-7602179 from the National Science Foundation. The authors wish to thank Russ Fazio for his help in collecting the data and Al Rogers and Terry Balaban for their help in analyzing the data. Diane N. Ruble is now at New York University. Ann K.
