This essay explores the current and historical meaning of forgiveness in Arab and Islamic cultural and religious contexts. It also hopes to encourage further empirical research on this understudied topic in both religious and peacebuilding studies. In addition to the perceived meaning of forgiveness in an Arab Islamic context, this essay examines the links between forgiveness and reconciliation. Relying on religious sources including the Qur'an and Hadith, as well as certain events in Islamic history, the essay identifies various ways to conceptualize and explain the meaning of forgiveness. This theoretical and conceptual segment is followed by a section which explores current perceptions of forgiveness among Arab Muslim teachers in five different communities. The empirical data for this analysis is based on a larger comparative regional study that has been completed through surveys and structured interviews with educators from Lebanon, Jordan, Egypt, and Palestinians from the West Bank and Israel. Our study concluded that the teachers' perceptions of forgiveness were mainly derived from religious sources and identities and that Islamic religious discourse provided a solid foundation for framing the meaning of forgiveness.  相似文献

This paper summarizes three lines of research that are motivated by the practical problem of helping users find information from external data sources, most notably computers. The application areas include information retrieval, text categorization, and question answering. A common theme in these applications is that practical information access problems can be solved by analyzing the statistical properties of words in large volumes of real world texts. The same statistical properties constrain human performance, thus we believe that solutions to practical information access problems can shed light on human knowledge representation and reasoning.  相似文献

Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3‐year‐old children and their parents, who provided data at baseline and 1 year later. Parents completed self‐report body size attitude and dieting measures. Child weight bias and awareness of weight loss strategies were assessed through interview. Over time, negative associations with large bodies and awareness of weight loss strategies increased. Fathers’ attitudes prospectively predicted boys’ weight bias and awareness of weight loss strategies. Among girls, parental attitudes were less predictive. Findings confirm the importance of fathers in the development of boys’ body attitudes and inform prevention programmes.  相似文献

The ability of two species of tits to remember the location and/or features of an object was tested in a delayed-matching-to-sample procedure. Three values of retention interval between presentation of the sample stimulus and the choice--30 sec, 5 min, and 15 min--were used. Both species performed at above-chance level at all retention intervals, and there was no significant decline in accuracy with increasing interval. A pool of 100 stimulus objects was used, but the results of control trials indicated that the birds responded primarily to location rather than stimulus features of the object itseif. Although the food-storing marsh tit tended to perform at a higher level than the non-storing great tit, the only significant difference between the species was in the first 50 trials of the first treatment, when the birds were acquiring the task. The results are discussed in relation to the hypothesized special memory capacity of food-storing birds.  相似文献
