Item Restricted From Religious Legitimacy to Cultural Nationhood: How Vision 2030 Coordinates the Reconstruction of Saudi Identity Through Heritage, Architecture, and the Creative Economy(Saudi Digital Library, 2025) Alotaibi, Layla; Acikgoz, GizemThis thesis examines how Saudi Arabia deploys culture as a strategic instrument of governance, identity construction, and soft power under Vision 2030. It addresses a gap in existing scholarship that often treats cultural reform as symbolic or externally oriented, rather than as a tightly coordinated state project entrenched within institutional systems. The central argument is that Vision 2030 represents a shift in Saudi legitimacy. This shift is from an overwhelming reliance on religious authority toward a diversified cultural and nationalist framework that operates domestically and internationally. Methodologically, the thesis employs qualitative analysis of policy documents, institutional structures, cultural initiatives, along with case studies on AlUla, the Saudi Architecture Characters Map Initiative, and the creative economy industry. The findings demonstrate that Saudi cultural governance is highly centralized and deliberate, shaping national identity through curated heritage narratives, spatial and aesthetic regulation, and institutionalized cultural production. The thesis concludes that culture under Vision 2030 functions as a form of symbolic governance, revealing both the generative power and selective limits of state-led cultural transformation.18 0Item Restricted Diversity, Equity, and Inclusion (DEI) in Performance Management in the Public Sector: A Comprehensive Analysis of Literature, Laws, and Stakeholders' Perceptions(Saudi Digital Library, 2025) Alshaikh, Aiman; Tantardini, MicheleThis dissertation explores the integration of diversity, equity, and inclusion (DEI) into performance management in Saudi Arabia’s public sector, addressing its role in enhancing organizational effectiveness in non-Western contexts. Through three studies that include a systematic literature review, a contextual analysis of U.S. and Saudi DEI legislative frameworks, and an empirical study of Saudi public sector stakeholders, the dissertation investigates the conceptual foundations, legislative frameworks, and stakeholder perceptions of DEI. The literature review develops a theoretical framework, identifying DEI’s potential to boost employee engagement, innovation, and service quality, while noting barriers like bureaucratic inertia, conceptual ambiguity, and an overemphasis on economic motives. The contextual analysis highlights the U.S.’s robust DEI legislation contrasted with Saudi Arabia’s Vision 2030-driven modernization, which faces cultural and institutional constraints requiring context-sensitive adaptations. The empirical study reveals stakeholders’ moderate optimism for inclusive appraisal systems, tempered by challenges such as resistance to change and limited institutional capacity. The findings underscore the need to align organizational values, governance systems, and capabilities within Saudi Arabia’s socio-cultural context for effective DEI integration. The dissertation contributes a multidimensional framework to public administration scholarship. It offers practical recommendations, including culturally relevant practices and leadership training, while proposing future research, such as longitudinal and comparative studies, to foster inclusive, accountable public organizations in Saudi Arabia.7 0Item Restricted Hospitality for All: Building Inclusive Experiences for Individuals with Down Syndrome in 5-Star Hotels in Saudi Arabia(Saudi Digital Library, 2026) Alkhudairy, Shahd Ibrahim M; Cattaneo, Eleonoraتهدف هذه الدراسة إلى استكشاف سبل تعزيز الشمولية في فنادق الخمس نجوم في المملكة العربية السعودية للأفراد من ذوي متلازمة داون، من خلال توسيع مفهوم الإتاحة ليشمل الجوانب العاطفية والمعرفية والاجتماعية، وليس الجوانب المادية فقط. تنطلق الدراسة من رؤية المملكة 2030 التي تشجع على دمج جميع فئات المجتمع ضمن قطاع السياحة والضيافة. اعتمد البحث منهجية نوعية تفسيرية، من خلال مقابلات شبه منظمة مع خمس عائلات لديها أفراد من متلازمة داون، وأربعة من مديري الفنادق في الرياض وجدة ومكة، إضافة إلى مقارنة معيارية مع نموذج دولي رائد في الشمولية الفندقية. وأظهرت النتائج وجود فجوة واضحة بين الإتاحة المادية وبين الممارسات الشمولية الفعلية، حيث واجهت الأسر تحديات تتعلق بالتحفيز الحسي الزائد، وصعوبة التنقل، وضعف التواصل الداعم. كما أشار المديرون إلى محدودية التدريب المتخصص وغياب السياسات الوطنية رغم استعدادهم للتحسين. خلصت الدراسة إلى أن الشمولية الحقيقية تتطلب تدريبًا متخصصًا للموظفين، وتصميم بيئات حساسة للمثيرات، وتوفير أدوات مساعدة للتواصل، بالإضافة إلى إشراك الأسر في تجربة الضيافة. واقترحت الدراسة إطارًا تشغيليًا يعزز الممارسات الشمولية ويسهم في تحسين جودة الحياة وتجربة الضيف في الفنادق الفاخرة داخل المملكة This research investigates how five-star hotels in Saudi Arabia can enhance inclusion for people with Down Syndrome by broadening accessibility beyond the physical realm to include emotional, cognitive & social aspects. This is part of the Vision 2030 social inclusion agenda and tackles the shortage of formal policies, training, and practices for neurodivergent guests within the luxury service industry. This research employs an interpretative, exploratory qualitative case study methodology, utilizing semi-structured interviews with five families of individuals with Down Syndrome, four hotel managers, and an international comparator, The Langham London. Data were analysed using the Social Model of Disability, Universal Design, and Service-Dominant Logic frameworks, and the lived experience and operational interface were approached via Braun and Clarke’s reflexive thematic methodology. Intersectionality of the lived experience and operational interface. There is an absence of genuine inclusion, demonstrated by families' emotional anguish due to sensory overload, unpredictable settings & inadequate communication. Supporting the notion of operational interfaces, managers expressed a willingness to incorporate inclusivity yet described an absence of frameworks within which to situate operational practices. Benchmarking illustrated an industry-wide empathy training deficit, lack of sensory-responsive design, and absence of norms. The focus on Guest Emotional Care in Healthcare applies to visitors, patients, and hospital staff, illustrating the importance of emotional support. Care Continuum Framework aims for emotional safety, cognitive clarity, and partnership on all levels: family, staff & patients. Incorporation of staff sensitivity training focused on disabilities, family partnership in design, sensory friendly environments, and digital to physical navigation systems coupled with a national inclusive hospitality certification. This research framed inclusivity in a new light and focused on the inclusivity of the Family and staff in the Care. It also assisted in the repositioning of Saudi Arabia and its tourism as inclusive luxury and allows the Family to enjoy the luxury of a holiday. It also provides support and empowerment to staff in the Family Care.6 0Item Restricted An Analysis of Face Synthesis Methods and Their Influence on Human Perception(Saudi Digital Library, 2025) Almaimani, Maha; Patterson, EricSynthetic faces (e.g., computer-generated characters) have been increasingly utilized across various fields, including entertainment, healthcare, and education. Perceptual studies are often con- ducted to understand how synthetic faces are perceived by humans, aiming to enhance both quality and user experience in these domains. Over the years, numerous methods have been developed to create synthetic faces, ranging from traditional techniques such as image composites, Active Ap- pearance Models, and 3D Morphable Models to more recent machine-learning-based frameworks like Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs). Despite the growing adoption of synthetic face generation and the variety of algorithms available for their creation, cognitive scientists have underutilized these advanced techniques. Re- search in this area has remained largely dependent on earlier approaches, and even when Artificial- Intelligence-based (e.g., AI-based) methods are employed, there is an overreliance on GANs, particu- larly StyleGAN2. This trend highlights a significant gap in the exploration of alternative generative architectures in perceptual studies. Furthermore, existing studies have primarily focused on the technical performance of GANs and VAEs, while human perception of their outputs has remained underexplored. This dissertation seeks to address this gap by first providing a comprehensive review of syn- thetic face generation methods from a perceptual standpoint. Second, it analyzes and perceptually compares two prominent AI-based models: StyleGAN2 (a GAN variant) and NVAE (a VAE flavor) across multiple contexts (e.g., full scenes vs. isolated faces without background, and animated vs. static faces) to determine how these conditions influence perceived realism and trustworthiness. This comparison supports the development of cognitive research that advances the generation of percep- tually engaging and practically useful synthetic faces. Finally, conducting a study to investigate how truthful versus misleading medical information about dementia influenced participants’ perceptions when viewing videos of synthetic faces generated by StyleGAN2. The outcomes of this dissertation provide insights into the perceptual differences between GAN-based and VAE-based synthetic faces across diverse contexts. Understanding these distinctions will contribute to the responsible and effective application of synthetic faces in real-life applications.22 0Item Restricted Robust Multi-Layer Calibration of the Heston Stochastic Volatility Model: The Balanced Premium Calibration Method(Saudi Digital Library, 2026) Aldossari, Mohammad; Malham, SimonThis thesis presents the balanced premium calibration method (BPCM), a three-layer framework for robustly fitting the Heston stochastic volatility model to large option datasets. The BPCM method involves three layers. Layer 1 ensures market consistency by filtering and structurally repairing raw quotes via put-call parity and bid-ask bounds, separating stable observations from noise. Layer 2 performs daily least-squares calibration of the Heston parameters using closed-form characteristic function pricing and derived analytic gradients and Hessians, thereby achieving rapid convergence without finite-difference approximations. Layer 3 redistributes errors and allows for controlled adjustments to model inputs and outputs, absorbing residual pricing errors and restoring arbitrage-free consistency. Working with 1.5 million call and put quotes on a major equity from 2018 to 2024, BPCM ensured that model prices closely adhere to market bid-ask spreads (91.58% adherence) for stable regimes while maintaining realistic spot price behaviour. The calibrated model achieves high consistency with observed prices and reconstructs the underlying spot price trajectory with minimal deviation even during market crises. In addition to BPCM, this thesis derives explicit closed-form expressions for the Heston model's Hessians.21 0Item Restricted Prevention of Gestational Diabetes Mellitus (GDM); Targeting Early Pregnancy Intervention to Women at Risk(Saudi Digital Library, 2025) Quotah, Ola; Poston, LucillaBackground: Gestational diabetes mellitus (GDM) is a common metabolic disorder of pregnancy, particularly among women living with obesity. GDM is associated with increased risk of short- and long-term adverse consequences for both the mother and her infant. Identification of women at high risk of developing GDM would facilitate targeted intervention in those who would benefit the most. This thesis comprises different studies, each aimed at enhancing the understanding, prediction and prevention of GDM in women who are at increased risk of the condition. Overarching aim: To identify pregnant women at higher risk of developing GDM and test the feasibility and efficacy of diet and/or metformin to improve glucose homeostasis and pregnancy outcomes. Methods: This thesis consists of a systematic review and meta-analysis in addition to three distinct studies. These are outlined below: i) ii) iii) Study (1): studies evaluating behavioural/pharmacological interventions or dietary supplements in the preconception period and in pregnant women with greater risk of developing GDM were assessed and evidence synthesised using a systematic review and meta-analysis. Study (2): Using a prospective cohort (the GDM validation study), the performance of two pragmatic GDM prediction tools (model 1 and model 2) was compared in women with obesity. Study (3): A secondary analysis was performed using data collected from women who took part in the UPBEAT study (UK Pregnancy Better Eating and Activity Trial). This analysis compared metabolic profiles in women identified as high-risk of developing GDM using the prediction tool, stratified by GDM diagnosis. Analyte 13 iv) data, measured using a nuclear magnetic resonance platform and conventional assays, were compared between women who developed GDM and those who did not in early (15+0 –18+6 weeks’ gestation) and mid-pregnancy (23+2 –30+0 weeks’ gestation). Study (4): A preliminary feasibility and Patient-Centred outcomes analysis of UPBEAT- Taking it Forward (TIF) was carried out. UPBEAT-TIF is an ongoing randomised controlled trial (RCT) of lifestyle advice with or without metformin compared to standard antenatal care in individuals identified as high-risk of developing GDM using the prediction tool. Results: i) Study (1): The systematic review and meta-analysis identified eighty-four RCTs (preconception=2, pregnancy=82). The review provided evidence that interventions targeted at women at risk of GDM may be an effective strategy for GDM prevention and highlighted the need for further studies using validated prediction tools or multiple risk factors to target high-risk women for intervention before and during pregnancy (Quotah et al., 2024). ii) Study (2): Model 2 incorporating non-biochemical factors (age/mid-arm circumference/systolic-blood pressure), haemoglobin A1c (HbA1c), glucose and triglycerides demonstrated a higher performance in predicting GDM compared to model 1 with non-biochemical factors, HbA1c and adiponectin (AUC 0.755 vs AUC 0.637; p=0.006). Model 2 could facilitate early detection among women with obesity and increased risk, enabling timely implementation of targeted lifestyle or pharmacological interventions for those who are most likely to benefit. However, external validation of the models' performance is underway. 14 iii) Study (3): The secondary analysis revealed biochemical differences between women with obesity identified as high-risk using the predictive tool who went on to develop GDM compared to those identified as high risk who did not. These differences were found both early in gestation and at the time of GDM diagnosis. The identified differences may be related to defective β-cell secretory function (Quotah et al., 2022). iv) Study (4): The preliminary feasibility analysis of UPBEAT-TIF RCT demonstrated that a targeted intervention in women at increased risk of GDM is a feasible approach. Preliminary analysis of outcomes did not support the use of lifestyle interventions with or without metformin to improve glucose concentrations among women who are at increased risk of GDM. The unexpectedly low rates of GDM across all groups, including the controls, warrant additional explorations. At the time of writing, recruitment to the study had not yet reached the predefined sample size. Conclusion: Overall, this thesis makes innovative contributions to understanding GDM pathophysiology and identifying high-risk women in order to assess the potential benefit of interventions. Intervention studies in the preconception period and in early pregnancy that target women at increased risk of GDM using multiple risk factors or validated prediction tools are warranted, as a strategy towards prevention of GDM and improved maternal and infant health among those who would benefit the most.14 0Item Restricted Bioinspired In Vitro Model for Investigating Intravenous Catheter-Related Bloodstream Infections(Saudi Digital Library, 2024) Althumayri, Majed Othman H; Koydemir, Hatice CIntravenous (IV) catheter-related bloodstream infections (CRBSIs) are a significant risk in healthcare, driving the need for better catheter designs and materials like Ecoflex to enhance safety. This study explored Ecoflex's effectiveness in reducing CRBSIs by creating skin-like replicas that mimic human skin properties for catheter design and training tools. We conducted experiments to evaluate the material’s surface roughness, wettability, bacterial adhesion, mechanical properties, and thermal stability. The study included wettability tests under varying sebum levels, bacterial adhesion experiments with E. coli, and mechanical stress tests that mimic daily usage. The Ecoflex replicas accurately replicated human skin textures with controlled surface roughness and improved hydrophilicity upon sebum application. Simulation tests of IV therapy scenarios demonstrated the material's resistance to bacterial growth, indicating its potential for prolonged medical use. Ecoflex shows promise for medical device manufacturing, particularly for studying bacterial adhesion and enhancing catheter safety. The study suggests further microbial studies and better IV-therapy clinical simulations to develop safer medical devices and reduce hospital-acquired infections.36 0Item Restricted IPO Governance in Saudi Arabia's Energy Sector: Legal Structures, Compliance, and Reform under Vision 2030(Saudi Digital Library, 2025) Aljohani, Mohammed; Nigro, CasimiroThis thesis examines the legal and institutional dimensions of initial public offerings (IPOs) in Saudi Arabia’s energy sector, with a focus on how corporate governance, compliance, and ESG mechanisms are formalized within state-owned enterprises (SOEs) undergoing partial market exposure. IPOs in this context are not solely financial transactions but are also instruments of institutional transformation—tools that enable alignment with international standards while accommodating sovereign policy priorities. Employing a doctrinal legal methodology supported by a case study of Saudi Aramco, the research investigates how statutory provisions, Capital Market Authority regulations, and corporate governance codes shape the IPO process, particularly in relation to board independence, disclosure obligations, and sustainability oversight. The findings reveal that although the Saudi regulatory framework demonstrates formal convergence with global governance norms, its implementation reflects selective adaptation, shaped by the continued presence of state ownership through entities such as the Public Investment Fund. The thesis further explores how IPO governance structures are designed to advance transparency, investor confidence, and ESG integration, while retaining flexibility for national development strategies under Vision 2030. In doing so, it contributes to corporate governance literature by offering a nuanced understanding of hybrid regulatory models, where public-sector priorities and market-facing reforms coexist. Ultimately, the study argues that IPOs in Saudi Arabia’s energy sector function as calibrated mechanisms of governance modernization, balancing legal compliance, institutional credibility, and sovereign interests, rather than serving as vehicles of full privatization or market liberalization.7 0Item Restricted Motion Events Conceptualisation in Arabic and English: A Study on Monolingual and Bilingual Speakers.(Saudi Digital Library, 2026) Aljohani, Eman; Aveledo، Fraibet; Kasprowicz, RowenaThis thesis investigates the typological characteristics and cross-linguistic influences in the encoding of motion events among monolingual Arabic speakers (MA) and bilingual Arabic–English speakers (BAE). Grounded in Talmy’s (1985, 2000) and Slobin’s (1996, 2003) typological frameworks, the research addresses two primary questions: (1) What are the typological patterns of motion event structures preferred by Arabic speakers, and how do these align with verb-framed languages? (2) How does cross-linguistic influence manifest in bilingual Arabic–English speakers when encoding motion events in their second language (English) and their first language (Arabic)? The study particularly emphasises the restructuring of conceptualisation patterns arising from bilingualism, focusing on Arabic, a typologically distinct and under-researched language. The research adopts a quasi-experimental, quantitative approach using two elicitation tasks: a controlled video description task featuring dynamic motion events, and an elicited narrative task using the picture book Frog, Where Are You? (Mayer, 1969). Participants included 30 monolingual Arabic speakers, 30 monolingual English speakers, and 90 bilingual Arabic–English speakers with varied proficiency levels and ages of second language acquisition. Results indicate that MA speakers adhere closely to verb-framed typological patterns by prioritising path verbs, minimally using clausal packaging, and exhibiting relatively detailed ground elaboration. BAE speakers displayed hybrid lexicalisation patterns with task-sensitive cross-linguistic influences in L2 English. Selective and context-sensitive reverse transfer was evident in their L1 Arabic, particularly influenced by L2 proficiency. The findings significantly enhance understanding of bilingual restructuring of conceptualisation patterns, underscoring the nuanced, selective, and proficiency-driven nature of cross-linguistic influences. Practically, these insights can inform targeted second language teaching methodologies, effective translation strategies, and improved intercultural communication between Arabic and English speakers.8 0Item Restricted Linguistic and Multimodal Character Construction in Arabic Dubbing A Comparative Analysis of Original dubbing with Egyptian Arabic and Modern Standard Arabic in Disney Animation.(Saudi Digital Library, 2025) alhanaya, amjad; pinto, sara ramosThis study examines how linguistic variety in Arabic dubbing-specifically the use of Egyptian Arabic (EA) and Modern Standard Arabic (MSA)-affects character construction, multimodal cohesion, and audience engagement in animated films. By comparing the English source text (ST) with its Arabic-dubbed versions, this research investigates the interplay between linguistic and non-linguistic elements, such as gestures, visual representation, and character behaviour, in shaping audience perception. The study employs a mixed-methods approach, integrating qualitative multimodal discourse analysis with quantitative corpus-based examination. Three Disney films-Cinderella (1950), The Lion King (1994), and Pocahontas (1995)-serve as the core corpus, providing a diachronic perspective on the shifts in dubbing strategies. A structured dataset documents character-specific linguistic varieties, intermodal relationships, and translation choices across the English, EA, and MSA versions. The analysis applies the framework of Ramos Pinto & Mubaraki (2020) to assess whether linguistic choices align with, contradict, or exist independently of non-linguistic elements. Findings reveal that EA dubbing enhances character expressivity, humor, and audience relatability, particularly for comedic and emotionally driven roles. In contrast, MSA is often associated with formality and narrative authority but may create communicative distance, especially in character-driven interactions. The study also highlights how industry-driven language policies have shaped the transition between EA and MSA dubbing, reflecting broader ideological and sociopolitical considerations. By bridging sociolinguistics, audiovisual translation, and multimodal analysis, this research contributes to the understanding of how language choice in dubbing influences character portrayal, cultural representation, and audience reception. The findings have broader implications for dubbing practices in Arabic media localization and global audiovisual translation strategies.4 0
