State universities in Saudi Arabia have adopted a new educational policy, which made English the medium of instruction for all scientific departments. This has led to establishing a Foundation Year Programme (FYP) in the English Language Institute (ELI) of those universities, which aims to prepare university students to cope with the new academic requirements in their chosen majors and to improve their overall language competence. This study investigates teachers’ roles and beliefs regarding assessment practices in the ELI with the aim to uncover not only the role(s) teachers play in both continuous and summative assessment practices, but also teachers’ understandings of and attitudes towards assessment and their roles in it. Findings will also include how teachers perceive this role in this interpretive study, where the data were collected using open-ended interviews with twenty male and female expatriate and Saudi EFL teachers who work in the ELI of a specific Saudi university. The data were analysed on the basis of participants’ views and explanations about their roles in both continuous and summative assessment in the institution. The findings revealed that teachers had no role in summative assessment unless they were members of the Assessment Committee and that most teachers wanted to have a voice and be more involved. While teachers had a limited role in continuous assessment in the classroom, they felt the need for more involvement in the choice of materials/topics employed as well as more freedom regarding the way it is administered. The study also revealed that the ELI was not well receptive of criticism from teachers, which made teachers sometimes reluctant to being more involved in assessment or voicing their views in fear of being labelled negatively. Finally, some contributions to knowledge, implications for the context and recommendations are provided as well as some suggestions for improving teachers’ roles in assessment for future consideration.

Due to the current practices of street design in countries with hot and humid climates that prioritise air-conditioned cars as the favoured mode of transport, the physical and spatial characteristics of the street space have failed to retain much or any user-friendliness for walking or for sustaining street life. Moreover, particularly in Saudi Arabia, the increasingly sedentary lifestyle is leading to significant health problems and prevalence of lifestyle diseases. However, there has been limited research conducted on the use of urban streets under hot and humid conditions, and even less is known about the impact of certain sociocultural aspects in, for example, Muslim countries, on the design of streets for walking. Such a situation poses challenges to the urban space researcher and designer interested in gaining a better understanding of how walking can be restored into the street space. This thesis contributes to the advancement of knowledge in this area by integrating three influential factors connected to walking in a single study; an approach which has not been elaborated previously. This thesis aimed to broaden the understanding of pedestrians’ requirements, attitudes and preferences in order to identify ways in which the neglected street space can be reclaimed for walking under hot-humid climatic conditions and to inform decision-making into improved street design. The scope of this research centred on combining an understanding of pedestrians’ thermal comfort in a hot and humid urban environment, that of the city of Dammam in Saudi Arabia, where the problem is particularly acute, coupled with exploration into the socio-cultural aspects through which behaviour such as undertaking increased physical activity is governed. The research postulated an interactive relationship between the existing conditions of the street space and these two factors. Owing to the multifaceted nature of the factors affecting an individual’s choice to walk, there are few accepted theoretical frameworks, hence studying the cause-and-effect relationship between street design and walking is challenging. Following the literature review and analysis of existing street characteristics; the strategy of mixed-method data collection combining participant observation with interviews and a questionnaire was conducted. The findings revealed the dual impact of key street characteristics on pedestrians’ reluctance to walk on streets and this led to two levels of simultaneous interventions being suggested: physical and spatial. The analytical process (1) identified the upper thermal comfort limit for pedestrians by application of the Physiological Equivalent Temperature index, ‘PET’, through use of the RayMan Software; (2) revealed that physical proximity to other people while on the street is the most sensitive socio-cultural issue in the outdoor spaces of Saudi, particularly between the opposite sexes, and that the existing pavements are generally too narrow to accommodate the preferred personal distance; (3) identified appropriate design interventions at the microscale of the street space to introduce improved shading and create air movement to reduce the impact of solar radiation and humidity and thus to contribute towards encouraging more use of streets for walking; and (4) marking the pavement to indicate distance walked along with high quality streetscape elements was shown to attract pedestrians effectively. Such findings have significant implications for restoring the place of walking on streets in hot and humid cities and the research concludes by emphasising: (1) it is the design of the street space in climatically responsive and socio-culturally compatible ways, rather than the configuration of the urban form that is most associated with increasing physical activity; (2) there is a crucial need to redistribute the street space away from cars and towards pedestrians by widening the existing pavements both for satisfying the average personal comfort distance between pedestrians and for incorporating appropriate streetscape elements.

Concern for project failures and successes have posed a controversial and much debated topic amongst scholars and practitioners alike. IT projects are no exceptions and they too suffer from a high rate of failure. This research aims to explore the reasons why certain IT projects succeed). Besides its academic importance, the research intends to assess the implications for successful implementation of current and future IT projects. The review of the extant literature reveals the enormity of the challenges involved in minimising or avoiding project failures. Present work is contextualizing these issues in a large national organisation with branches throughout the KSA. The Saudi Arabia constitutes the case study for this research. Qualitative methodology was adopted to generate and collect adequate and relevant data. Main instruments were; Semi-structured interviews involving senior managers in five geographical areas who were involved in the management of the IT projects and selected project documents. Thematic analysis was used and led to emergence of seven main ‘themes’, 19 major ‘issues’, and the construction of the first time generic model for success of IT projects. The core issues identified in the model are: Quality, Time and Cost at three levels; individual, organisation and environment with specific order of importance. The implications of the findings for the theory and practice have been identified. It is also recommended that there is a need for further research into individual and contextual factors that influence both managers as well as the circumstances under which IT projects are implemented.

This work contributes to the multi-disciplinary community of researchers in computer science, information technology and computer forensics working together with legal enforcement professionals involved in digital forensic investigations. It is focused on the relationship between scientific approaches underpinning digital forensics and the Islamic law underpinning legal enforcement. Saudi Arabia (KSA) is studied as an example of an Islamic country that has adopted international guidelines, such as ACPO, in its legal enforcement procedures. The relationship between Islamic law and scientific ACPO guidelines is examined in detail through the practices of digital forensic practitioners in the process of discovery, preparation and presentation of digital evidence for use in Islamic courts in KSA. In this context, the influence of religion and culture on the role and status of digital evidence throughout the entire legal process has been the main focus of this research. Similar studies in the literature confirm that culture and religion are significant factors in the relationship between law, legal enforcement procedure and digital evidence. Islamic societies, however, have not been extensively studied from this perspective, and this study aims to address issues that arise at both professional and personal levels. Therefore the research questions that this study aims to answer are: in what way and to what extent Islamic religion and Saudi culture affect the status of digital evidence in the KSA legal process and what principles the practitioners have to observe in the way they treat digital evidence in judicial proceedings. The methodology is based on a mixed-method approach where the pilot questionnaire identified legal professionals who come into contact with digital evidence, their educational and professional profiles. Qualitative methods included case studies, interviews and documentary evidence to discover how their beliefs and attitudes influence their trust in digital evidence. The findings show that a KSA judge would trust witnesses more than digital evidence, due to the influence of tradition, which regards justice and law to arise from the relationship between Man and God. Digital evidence, as it arises from the scientific method, is acceptable, but there is underlying lack of trust in its authenticity, reliability and credibility. In the eyes of the legal enforcement professionals working in all areas of the KSA legal process, acceptance of digital evidence in the KSA judicial system can best be improved if knowledge, education and skills of digital forensics specialists is improved also, so that they can be trusted as expert witnesses. This further shows the significance of KSA laws, regulations and education of digital forensic experts as the primary means for establishing trust in digital evidence. Further research following from this study will be focused on comparative studies of other Islamic non-Islamic legal systems as they adopt and adapt western guidelines such as ACPO to their religion, culture and legal systems.
