Counseling has been slowly developing in the Arab countries. In 1984, Kuwait University organized a Conference on Psychological and Educational Counseling. Twenty-four professionals presented papers at this conference. A questionnaire which dealt with the status, rationale and development of counseling in the Arab countries was administered to these professionals. All the participants completed and returned the questionnaire. The majority of the participants reported that counseling services are offered in their institution and countries. They also reported that counselor education programs do not exist in their countries. They perceived that development (economic, social, and personal) is the number one rationale for counseling in the Arab countries. The implications of these views for the development of counseling in the Arab countries were discussed.Kuwait University 相似文献

While there is an increasing demand of academics to do more teaching, research and community service, there is also increasing pressure to improve the quality of such work. The emerging dilemma between increasing the quantity and quality of academic work and its implications are the focus of this paper. Academic work appears to be taken for granted by administrators as it is rarely defined in contracts, either quantitatively or qualitatively. In this paper the complexity of the relationships between quantity and quality of academic work is analysed in terms of relevant concepts and processes. It is argued that the achievement of higher quality in academic work requires a better understanding of the factors involved by academics, administrators and the funding bodies responsible for higher education. 相似文献

A study was conducted to determine what sort of problems beset college students and whether they select different helpers for different problems. A two page questionnaire listing 20 common problems, and 18 different helpers was administered to 80 male and 155 female students at Kuwait University. It was found that males and females differed significantly on six problems (family, self-confidence, behavior, death, work and grades). Different helpers were selected for different types of problems, and for 18 of the 20 problems, males and females chose a same-sex helper. The results are explained within the context of the Arab culture and the implications for counseling are discussed.Paper presented at the meeting of the Fourteenth International Round Table for the Advancement of Counselling, Helsinki, Finland, July 1–5, 1990. 相似文献

This article focuses on three recently released reports — Schools Renewal (1989), Report of the Committee of NSW Schools (1989) and Excellence and Equity (1989) — which are examined from the perspective of the discourse of school and parent/community relations. After outlining the basic elements of this discourse, their status in NSW education is discussed and the extent to which they function as a framework for the changes the reports propose or as a legitimating mechanism is analysed. This is followed by an appraisal of the context which gave rise to the reports and of the implications for the future role of parents’ and citizens’ groups. 相似文献

Query Expansion (QE) is one of the most important mechanisms in the information retrieval field. A typical short Internet query will go through a process of refinement to improve its retrieval power. Most of the existing QE techniques suffer from retrieval performance degradation due to imprecise choice of query’s additive terms in the QE process. In this paper, we introduce a novel automated QE mechanism. The new expansion process is guided by the semantics relations between the original query and the expanding words, in the context of the utilized corpus. Experimental results of our “controlled” query expansion, using the Arabic TREC-10 data, show a significant enhancement of recall and precision over current existing mechanisms in the field. 相似文献

Development is an important goal for developing countries. This goal cannot be achieved without the growth of human potential. Counseling is one of the effective means for developing human potential. Yet counseling has been evolving slowly in developing countries. Reports show that counseling and guidance have been started in the schools in some of these countries; they rarely show that counseling has been implemented in other settings. The purpose of this paper was to examine the obstacles for implementing counseling services in developing countries, to discuss a working definition of counseling and to propose the settings in which counseling may be implemented.Paper Presented at the meeting of the Thirteenth International Round Table for the Advancement of Counseling, Calgary, Alberta, Canada, August 14–18, 1988. 相似文献

Summary This paper discusses the counselor's role as an agent of change in developing countries. Its main thesis is that the social and political systems in developing countries present special limitations for the counselor as an agent of change. Some alternatives which suggest ways to deal with these limitations are shown.Kuwait UniversityNinth International Round Table for the Advancement of Counselling, Thessaloniki, Greece, April 1980. 相似文献
