The purpose of this study was to examine the effectiveness of the current requirements of teacher evaluation at Saudi Arabian universities and to develop a teacher evaluation program that would fit the current need and support Saudi social and religious values. The site of the study was Ring Abdulaziz University (R.A.U.) in Jeddah, Saudi Arabia. Population of the study included a random sample of senior students and faculty from the Women's Section of the university. Of 350 surveyed students, 224 responded, and 55 out of 150 surveyed faculty responded. The Dean and the Vice Deans of the Colleges of Science, Medicine, Arts and Literature, and Economics and Administration in the Women's Section were interviewed. The study involved two phases. The first phase was the assessment, for which interviews and surveys were employed. Interviews of top administrators at R.A.U.'s Women's section had two aims: to get top administrators' views of the current requirements of teacher evaluation at K.A.U., and to define the need for employing a formal system of teacher evaluation. The faculty survey sought faculty members' views on the methods of instructor evaluation currently employed and their preferences regarding a wide range of instructional evaluation techniques. The student survey sought to ascertain students' wishes to improve the process of learning by participating in teacher evaluation. Development of a proposed teacher evaluation program followed an analysis of the interviews and surveys. The second phase of the study was the field review. The proposed teacher evaluation program was reviewed by a selected sample of 13 top administrators at K.A.U. in both the Men's and Women's sections and by two top administrators in both King Saud University and King Faisal University. Field reviewers were asked about program clarity and the feasibility of its employment. Findings from phase one, the assessment, indicated the need for a formal evaluation system to replace the currently employed practice of teacher evaluation. This finding led to the development of a teacher evaluation program that takes into account the felt need of students to participate in the evaluation process without fear of any kind of reprisal from faculty and the desire of faculty not to have their status within the university system compromised by such a process. Findings of phase two, the field review of the program, resulted in a revised and final version of the program. The final teacher evaluation program contains three major components: (1) campus orientation, designed to acquaint faculty and students with the program and help them to understand its purpose and adjust to its employment; (2) students' rating, which includes a questionnaire to be used by students to evaluate instruction, along with various options for administering the questionnaire; and (3) data analysis, interpretation and improvement strategies.

This study was conducted to evaluate the effect of curing and mix design parameters, such as cement content and water to cementitious materials ratio, on the strength and durability characteristics of plain and silica fume cements exposed to a hot-marine environment. Specifically, the effect of curing and mix design parameters on chloride diffusion, shrinkage and carbonation of cement mortar specimens exposed to a hot-marine environment was evaluated. The results indicated that high water to cement ratio significantly influenced the durability performance of concrete through: (1) accelerating chloride diffusion and carbonation, (2) increasing the shrinkage and weight loss, and (3) reducing the compressive strength. Similarly, increasing the cement content increased the shrinkage for a given w/c ratio. However, the chloride diffusion and carbonation were minimized and strength was enhanced due to increasing cement content. The mix design parameters, namely, water-cement ratio and cement content significantly influenced the performance of both Type I and Type V cements, while the influence of these parameters on the performance of silica fume cements was insignificant. Although Type I cement mortars performed better than Type V cement mortars, the performance of silica fume cement was the best in terms of reduced chloride diffusion, carbonation and shrinkage, and enhanced strength. The beneficial effects of silica fume cements, were however, only evident in specimens subjected to good curing. Therefore, to extend the useful service-life of reinforced concrete structures exposed to hot-marine environments, the following mix design is recommended: (i) cement content should not be less than 350kg/m³; (ii) Type I cement with 10% silica fume; (iii) water to cementitious materials ratio of not more than 0.45; (iv) good curing.

This study investigates the prospects of setting up an open university for women in Saudi Arabia against the background of the problems which Saudi women face in pursuing higher education. A review is given of the development of modern public education for women since its beginning in 1960, with emphasis on the more recent development of higher education for women. The position of women in Islam and in contemporary Saudi society is examined as this has influenced their access to higher education. An account is also given of the development of women's position in contemporary Western society. Three open universities, the United Kingdom Open University, the Sukhathai Thammahirat Open University (Thailand), and the Allama Iqbal Open University (Pakistan) are described in 'order to demonstrate how the idea of an Open University first arose (UKOU) , and how it was later realized in a developing county (Thailand), and in an Islamic country (Pakistan). A questionnaire was devised in order to gather data on attitudes to the setting up of an open university for women in Saudi Arabia, on perceptions of its feasibility, and on possible obstacles to its foundation. The questionnaire also included a section on the most suitable model for an open university for women in Saudi Arabia. The questionnaire was distributed in government bodies and higher educational establishments in Saudi Arabia to policy makers, academics, and female students. An analysis of the data reveals a very positive response to the setting up of an open university for women in Saudi Arabia. Respondents, however, demonstrated a realistic awareness of the problems of gaining public acceptance for a new type of higher education and of the launching of a new project in a time of restrictions on government spending. Finally, on the basis of the findings from the survey, a proposal is made for the setting up of an open university suitable for women in Saudi Arabia today.

This thesis examines the effect of spatial resolution on lithological and alteration mapping using remotely sensed multispectral data. The remotely sensed data were obtained by the Thematic Mapper (TM) and Airborne Thematic Mapper (ATM) over two areas in the Arabian Shield. These were the Mahd Adh Dhahab and Jabal Said areas. The ATM data had a nominal spatial resolution of 7.5m, 5m, and 2.5m. In order to compare these data sets it was necessary to correct for, sensor- and scene-related distortions. This was achieved by calibrating each data set and converting them to reflectance units using ground spectra with a similar spectral resolution obtained with the Barringer Hand Held Ratioing Radiometer (HHRR) . The ATM data were also corrected for X-track shading by normalising the brightness of each column to that of the centre column. The result of X-ray and laboratory spectral analysis of samples collected from the study areas, support the presence of characteristic minerals associated with the alteration zones. The corrected data were analysed by a variety of techniques in order to enhance the geological information present in the data. These included false colour compositing, decorrelating stretching and band ratioing. The latter two techniques proved most effective for discrimination and several additional geological units and areas were identified which had not been mapped previously. Results further indicate that the increased spatial resolution of the ATM data did not permit greater discrimination than the TM data. This suggests TM data should prove to be a cost-effective way of mapping and detection of alteration zones in the Arabian Shield.
