Item Restricted ACCM-SME: A New Theoretical Framework for Adopting Cloud Computing Model for Small and Medium Enterprises in Saudi Arabia(University of Sussex, 2024-08) Alqahtani, Mohammed; Beloff, NataliaBackground: Cloud computing technology is widely adopted by small and medium enterprises (SMEs) in developed countries. However, many SMEs in developing countries, particularly Saudi Arabia, still rely on conventional technology like onpremises servers. With the Saudi government's Vision 2030 initiative launched in 2016, significant technological, cultural and economic transformations are anticipated by 2030. Therefore, it is essential to investigate the factors impacting Saudi SMEs' adoption of cloud computing services to leverage the benefits of Vision 2030 programmes. Aims and Objectives: This thesis aims to investigate the intention of Saudi SMEs to adopt cloud computing services from the perspectives of employees, IT managers and top managers. The objectives of this study are to review the current literature to explore the barriers and challenges that influence Saudi SMEs' adoption of cloud computing services, identify the most influential factors that impact the adoption of cloud computing services and validate an appropriate conceptual framework for understanding Saudi SMEs' adoption of cloud computing services. Therefore, a new theoretical framework, Adoption of the Cloud Computing Model by Saudi SMEs (ACCM-SME), was developed to evaluate the potential influence of 17 factors from four different constructs: technological, environmental, organisational and social contexts. Methods: This thesis employs a mixed-method approach that combines quantitative (questionnaires) and qualitative (semi-structured interviews) methods. The questionnaires gathered data from 412 Saudi SME employees in Riyadh city and conducted a statistical analysis. Before further analysis, the validity and reliability of the instrument used were assessed using SPSS software. Then, a hypothesis analysis was conducted using Structural Equation Modelling (SEM) through AMOS software. After that, the next stage was conducting the semi-structured interviews and collecting data from 15 IT managers and top managers and analysing them thematically. The results from both stages were integrated to understand the factors affecting cloud computing adoption and to provide recommendations for enhancing the adoption process. Results: The findings revealed that while cloud computing adoption in Saudi Arabia is still in its early stages, there is a growing trend toward broader adoption. The study identified key factors influencing cloud adoption by Saudi SMEs using a new framework (ACCM-SME) built on the TOE Framework and DOI theory. The ACCM-SME incorporates technological, organisational, environmental and social (user behaviour) factors. Quantitative and qualitative data analysis confirmed these factors' importance, as 12 out of 17 hypotheses have been accepted. Conclusion: These insights highlight the factors influencing this process and can help cloud providers enhance their services and strategies. Policymakers and business leaders can also use these findings to formulate strategies that facilitate cloud adoption among Saudi SMEs. In summary, this thesis significantly contributes to existing knowledge of cloud computing adoption among Saudi SMEs.8 0Item Restricted Design and rapid prototyping of orthopaedic device for lower limb fractures(The University of Manchester, 2024-05-31) Alqahtani, Mohammed; Bartolo, PauloBone fractures are a prevalent occurrence on a daily basis, posing significant challenges to healthcare systems in terms of hospital admissions, surgical procedures, and medication requirements. These fractures primarily result from either pathological conditions or highenergy trauma, including incidents such as car accidents, falls, and natural disasters. The treatment of bone fractures necessitates the use of bone fixation devices, which can be either internal or external, to provide stability to the injury, promote bone healing, and enable the patient to regain full functionality. The current designs of fixation devices, along with the materials utilised in their manufacturing, lead to fixators that are excessively heavy, lack comfort and lack of customisation to meet the unique requirements of individual patients. These concerns highlight the necessity of continued progress in the development of fixation devices to achieve improved and personalised medical treatments, with the aim of enhancing clinical outcomes and reducing costs. Therefore, the aim of this research project is to overcome the identified limitations by developing an innovative, customised, and optimised bone fixation system that is both costeffective and lightweight, while ensuring its structural integrity through the utilisation of topology optimisation, polymeric material and additive manufacturing. The bone fixation systems were successfully optimised, taking into consideration various loading conditions and mass reduction values. Fused deposition modelling additive manufacturing was employed to fabricate the optimised models. Subsequently, the bone fixation systems underwent numerical and mechanical evaluation and validation. The results indicate that an increase in mass reduction leads to higher stress and displacement, which can be attributed to material removal. Furthermore, it was observed that these optimised systems possess adequate mechanical characteristics, as evidenced by the IFM falling within the acceptable range and the stresses generated in the system remaining below the yield strength. This demonstrates the potential of utilising polymeric materials and topology optimisation in the development of bone fixation devices. This research presents a novel approach involving the use of polymeric materials and topology optimisation to create custom fixation devices tailored to individual patient anatomy. This is the first type of fixation that could represent a potential alternative to the existing conventional fixations, offering promising prospects.7 0Item Restricted Comparative Analysis of User Responses to Phishing: Emails vs Mobile Instant Messaging Apps(University of the West of England, 2024-06-20) Alqahtani, Mohammed; Gorine, AdamAs phishing gets more sophisticated and multiple tactics are employed across various communication mediums, analysing users’ responses becomes increasingly essential. The extensive literature review indicates that most studies focus on a single medium across different communication platforms, necessitating additional effort. This research paper compares users’ responses to phishing attacks via two major communication platforms: Email and Mobile Instant Messaging (MIM) Apps. Understanding how users recognise and respond to phishing incidents is crucial for improving cybersecurity measures. A structured survey was conducted to investigate multiple dimensions of user interaction with phishing, such as self-reported confidence in phishing identification, frequency of phishing experiences, reliance on specific features for identification, and actions taken in response to suspected phishing attempts. The results reveal several key insights: 1) the study identifies the demographics of users most vulnerable to phishing attacks; 2) it highlights the similarities and differences in what prevents phishing messages from targeting the inbox and app interception; The study also offers recommendations to enhance users’ willingness and capability to withstand phishing attacks, including targeted educational campaigns, more convenient reporting options, and changes in the design of digital communication platforms.20 0Item Restricted Zipporah Overseas Market Research(Saudi Digital Library, 2023) Alqahtani, Mohammed; Mostert, AndreConsulting research for the company's international expansion.11 0
