M.A.S. Abdel Haleem 《Islam & Christian-Muslim Relations》1990,1(2):171-191
The story of Joseph in the Qur'an has been approached by many non‐Muslim writers1 who were content to list which details of the biblical story have been missed out from the biblical story and which points have been added, maintaining that these had their origins in biblical or other Jewish sources. Our treatment here concentrates on the texts of the story in the Qur'an and the Old Testament, attempting to identify the differing functions and preoccupations of the two accounts in their respective contexts, to show how this difference affects the choice of material and the treatment given to it. This article concludes that the two versions should be approached by readers, Muslims and non‐Muslims, with this difference in mind in order to appreciate the message and the qualities of each. 相似文献

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS).
Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as
cooperative unions and multinational companies are included. After considering the influence of the changing environment on
the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined.
Special attention is given to public and private R&D. The article then looks where information technology (IT) fits in and
what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences
with this strategic investment are evaluated. 相似文献

The termmultimedia refers to the combined use of different media of communication, and originally belonged primarily to the fields of entertainment and education. Advances in computer, audio, and video technology have now brought multimedia possibilities to the individual. Further, they give the user control over what happens. Suchinteractive multimedia systems offer the user personal access to large amounts of information, including pictures, graphics, video, text, and audio. The potential range of applications is very broad, from simple interactions where the user will merely make occasional choices and then sit back and view sections of program material, to more purposeful interactions where the application can help the user to achieve a goal. This article describes research onknowledge-based interactive multimedia systems. Targeted on the new Compact Disc Interactive format, we have protyped an advisor which will help the user to tackle a typical domestic task. The necessary decision-making process can be enlivened by multimedia interaction, and placed on solid ground by the inclusion of expert advice. 相似文献

Depression in some patients with spinal cord injuries may be clinically significant and, when present, should be treated to
decrease morbidity including decreased physical functioning. Depression associated with spinal cord injury (SCI) may be misevaluated,
due to (1) nonspecific multifactorial production of depression symptoms and (2) SCI-specific decrease in somatic sensory central
nervous system input. The Somatic Suppression Hypothesis suggests that SCI patients have difficulty experiencing any intense
emotion because of suppression of physiological arousal. In addition, cognitive processes that may reduce depression in SCI
patients include: (1) attribution of somatic symptoms of depression to medical (biological) causes, (2) realistic, positive
expectations for physical improvement, and (3) the perception that the disability of the SCI is only minimally related to
the patient’s self-care after complete evaluation. Health personnel should accept lack of depression in SCI, and should encourage
positive realistic expectations of recovery. 相似文献

Abstract. The paper consists of an argument that goes as follows. Symbols and their elaboration into myths constitute Homo sapiens 's most primitive reading of the world and the relation of humans to that world. They are, in other words, primordial units of cultural information, emerging very early in human history, representing a significant achievement in the evolution of human self-consciousness and reflection. The classic myths of Fall and Original Sin, as well as the doctrines to which they gave rise, are further interpretations of this primordial information. The doctrinal traditions of the first four centuries of Christianity are surveyed. Three sets of data as interpreted by the biological sciences are offered as resources for understanding the biogenetic grounds of the experience that the symbols, myths, and doctrines of Fall and Original Sin seek to interpret. The conclusions to be drawn are that (1) the symbolic material is indeed commensurate with the scientific understandings, and (2) the scientific interpretations deepen our understanding of the symbols, while (3) the conversation between the symbols and the science once again raises certain perennial questions about human existence. 相似文献

In the decade since professional counselor regulation was widely debated, more than half of the states have legislated regulation, and it is sought in others. The extent to which counselors in a state currently pursuing legislation are familiar with potential consequences of legislated regulation was examined. Most counselors were found to be unfamiliar with potential negative consequences of regulation, and most were desirous of more information regarding these issues. Implications of the findings for the profession are presented. 相似文献

Behavior analysis is a cultural system of which the Association for Behavior Analysis is a component cultural system. As cultural systems, they are composed of interlocking behavioral contingencies that constitute their cultural practices. Critical to the survival of both cultural systems is the frequency of interaction with and the nature of the content of the behavioral contingencies composing those cultural practices. The strengths of behavior analysis as a cultural system include its disciplinary character and its worldwide community of scientists and practitioners; its ability to be integrated into a scientific worldview; its track record in providing effective solutions to problems of importance to society; and the high levels of intellect, competence, and commitment that are characteristic of its participants. Weaknesses of behavior analysis are its status as an academic orphan, its relatively small size and its underdeveloped professional identity, and a lack of sociopolitical sophistication among many of its members. Behavior analysis will need to maximize its strengths and mitigate its weaknesses if it is to take advantage of the many opportunities available for growth in the modern world. 相似文献
