Item Restricted RESOURCE MANAGEMENT IN SAUDI ARABIAN MEGA PROJECTS(University of Kent, 2023) Alanazi, Abdulrahman; Badewi, AmgadThis thesis investigates the challenges and strategic solutions for effective resource management in Saudi Arabian mega projects, specifically focusing on projects such as NEOM, the Red Sea Project, and Mukaab. These mega projects, integral to Saudi Arabia's Vision 2030, require extensive resources and present unique management challenges. The study aims to identify these challenges, evaluate the effectiveness of current management practices, and develop a comprehensive framework for resource management. This framework is intended to improve the administration of current and future large-scale projects in Saudi Arabia. The research methodology includes a literature review, qualitative data collection through semi-structured interviews with project managers and stakeholders, and thematic analysis. Key findings highlight the importance of strategic planning, stakeholder collaboration, technological advancements, and sustainability in resource management. The study concludes with policy recommendations for stakeholders and practitioners to enhance the success of mega projects in Saudi Arabia.43 0Item Restricted Cultural Echoes in Stone & Concrete: A Journey Through Time and Architecture in Historic Jeddah’s Al-Balad(University of Westminster, 2024-01-10) Siraj, Talah Wabil; Bremner, LindsayLocated in the western region of the Arabian Peninsula on the Eastern coast of the Red Sea, my hometown, Jeddah, Saudi Arabia, has been a significant part in connecting extensive trading networks for centuries. Serving as the gateway to the holy cities of Mecca and Madinah, it is a harbour for Muslim pilgrims from around the world. Over time, it became a melting pot of different cultures and ethnicities, which shaped every aspect of the local lifestyle. Jeddah’s geographic location also unquestionably influenced its architecture in several ways; climatically, religiously, and culturally. The town’s architectural designs, building materials, traditions, and lifestyle were all in response to its context. The beautiful traditional houses were constructed using old building methods, with a combination of local and imported materials. The buildings functioned adequately to suit and serve the local lifestyle before the unification of the kingdom, and the discovery of oil, electricity, and concrete. Those pivotal historical events that took place in the 1930s marked the beginning of a transformative phase for Jeddah. The traditional construction methods and lifestyle were left in the past as Jeddah went through a stage of modern development. New buildings lacked cultural identity as a result of modernism and carbon energy. This dissertation is an autoethnographic study of the history of Jeddah’s old town of Al-Balad from both a technical and lifestyle perspective. Leveraging personal connections to the subject, I was able to visit the old town and acquire authentic information and material from primary sources, which helped me picture and analyse life in Al-Balad more vividly. This paper carries out an in-depth exploration of Jeddah’s history while examining the link between architecture and lifestyle in response to its diverse context, and the reasons why the traditional way of living was abandoned.19 0Item Restricted The geographical variation in colouration-based behaviours of the Arabian killifish (Aphaniops dispar)(University of Sheffield, 2024-06) Alfakih, Ateah U; Watt, Penelope J.; Nadeau, Nicola J.Animal colouration promotes essential biological functions, including sociosexual communication, thermoregulation, prey-predator interaction and protection from harmful radiation, which may be under conflicting pressures. One common technique to cope with colouration-based competing demands is colour change. However, colour change is susceptible to opposing selection pressures and varies intricately throughout taxonomic levels, and many areas remain unresolved, including how it evolves and interacts with other behaviours. In this thesis, I studied the geographical variation of colour change and its interaction with habitat preference in freshwater and marine populations of the Arabian killifish (Aphaniops dispar). In Chapter 2, I explored the taxonomic status of the species by examining morphometric, colour pattern and phylogenetic differences among populations. In Chapter 3, I examined the geographical variation of the achromatic and chromatic colour change and assessed their importance in conferring crypsis. In Chapter 4, I investigated the interaction between achromatic colour change, habitat preference and camouflage, and how these aspects varied between populations. The findings from Chapter 2 revealed distinct phylogenetic groups that were difficult to identify using morphometric and colour pattern analyses. The results from Chapter 3 indicated that all populations showed a greater ability to change colour achromatically, specifically becoming dark, which enhanced their camouflage. However, the chromatic colour change was more complex and varied within and between populations, but the marine populations generally showed greater chromatic responses than their freshwater counterparts. The outcomes of Chapter 4 showed that when given the choice between multiple achromatic substrates, the freshwater and marine populations did not change colour and displayed a similar habitat preference for darker substrates, despite being uncamouflaged against them. These findings highlight the importance of studying variation in colour change at the population level to understand its evolution at higher levels.49 0Item Restricted Different Approaches to Ancient Geography: Phytochemical Analysis and the Land of Punt(Saudi Digital Library, 2023-09) Andeejani, Abdulkareem; Wilson, PenelopeThe land of Punt and the centuries' old debate surrounding its location had long fascinated many onlookers, enchanted by depictions of a people and a land almost defined by frankincense. Incidentally, most the debates and research surrounding it had been almost devoid of any objects that could be called "Puntite" across the literature. Also incidentally, the defining object (frankincense) had never been examined to the end of identifying a geoprovenance. As such, this paper aims to outline a possible area that might have been considered "Punt" through an extensive literature review and reinterpretation in relation to archaeological frankincense in Egypt contemporaneous to contacts with Punt. Historical, philological, and artistic arguments that have dominated the debate were then placed against the results extrapolated from previous studies on archaeological frankincense to find a corresponding potential location to identify with Punt. The resulting location from the examination of different arguments through the perspective provided by the archaeological frankincense's geoprovenance led to the Bab el-Mandeb Strait being the most likely likely candidate.31 0Item Restricted Seafloor Classification and Marine Geohazards in the Coastal and Offshore Areas by Using Acoustic Techniques(Saudi Digital Library, 2023-12-01) Alqahtani, Ghazi Hussain Ali; Nanlal, CassandraIn tectonically active areas like the southern Red Sea, neotectonics plays a significant role in regulating the evolution of landforms. The Farasan Islands' fluvial systems have also been extensively impacted. In 2015, a high-resolution marine geophysical study was conducted in the southern Red Sea. It provided the first acoustic imaging of the sea floor across the Farasan Islands. The availability of such data enables the development of a 1-m digital terrain model for the area. The current study develops and proposes a method for reliably using digital terrain models generated using high-resolution marine acoustic methods to identify tectonic processes from geomorphology for the seafloor throughout the Farasan Islands. The drainage system and geomorphic conditions of the area have been severely impacted by tectonic activity. In light of structural geology, tectonics, and geomorphology, morphometric features of the seafloor across the Farasan Islands represented by digital terrain models will be retrieved, characterised, and interpreted. We describe a technique for calculating the index of relative active tectonics (IRAT), which is based on geomorphic indices obtained from digital terrain models of the seafloor beneath the Farasamn Islands and is useful for assessing topography and morphology. The five geomorphic indices that make up the basis of the current study are amplitude relief (Ar), the corresponding slope and aspect, the topographic wetness index (TWI), the terrain ruggedness index (TRI), the topographic position index (TPI), the slope-length gradient factor (LS-factor), and the stream power index (SPI). To identify relative tectonic activity within the plotted area, all indices were used. All the estimations were obtained using drainages and watershed basins extracted from the digital terrain models of the seafloor across the Farasan Islands in the Geographic Information System (GIS) environment. Based on the developed 1-m-resolution digital terrain models from the bathymetry of the seafloor across the Farasan Islands, drainage basins were extracted, and relative active tectonic geomorphic indices were estimated using the ArcGIS and SAGA-GIS software. The majority of the geomorphic indices were divided into five classes, and the relative ratios were arranged. For each class, the ratio of the number of drainage basins to the number of watershed basins for each geomorphic index was calculated and evaluated. The index of relative active tectonics (IRAT) was derived using the indexes' average class values. For each class of IRAT, the ratio between the number of drainage basins and watershed basins was calculated. The IRAT classifications were then used to define the probable risk level. Finally, the combined effect of the probable risk level and occurrence frequency of the morphotectonic feature was used to determine the active tectonic danger for each drainage basin. The findings demonstrated a strong correlation between IRAT classes and the ratio of morphotectonic valleys to drainage basins. On the sea bottom of the Farasan Islands, about 37% of the drainage basins with occured morphotectonic valleys are at a high-risk level, while 43% of the drainage basins without occured morphotectonic valleys are at a low-risk level. The remaining portion of the Farasan Islands' seafloor is regarded as having a medium risk rating. It has been found that after comparing with the past studies with the obtain results that provide higher accuracy which is greater than 87%. Therefore, it is a clear demonstration of the developed topography which had been bought though rapid electronic deformations it has higher chances of morphotectonic activity.17 0
