| 2025 | Adoption and Evaluation of Mobile Gaming Applications for Pain Management in Paediatric Oncology: A Culturally Contextualised TAM-Based Framework and Mixed-Methods Pilot Study in Saudi ArabiaabstractBackground: This pilot study has aimed to explore the adoption and effectiveness of mobile gaming applications as nonpharmacological tools for pain management in paediatric oncology within Saudi Arabia.Grounded in a culturally extended Technology Acceptance Model (TAM), the study has incorporated constructs such as Social Influence, Trust, System Quality, and Accessibility to understand technology uptake in a culturally conservative context.Problem: Current research lacks culturally adapted models that account for social, institutional, and technological factors affecting mobile app uptake in paediatric oncology-especially in non-Western contexts like Saudi Arabia.Methods: A mixed-methods pilot study was conducted at the King Fahad National Centre for Children's Cancer Emergency in Riyadh.Quantitative data were collected from 80 participants-50 parents and 30 healthcare providers-using a structured TAM-based survey instrument, with convenience sampling employed for feasibility.Composite Reliability (CR) was calculated using AMOS software as part of Structural Equation Modelling (SEM), with model fit indices such as CFI and RMSEA reported to validate the analytic model.In parallel, qualitative data were gathered from four participants (two parents and two healthcare providers) via semi-structured interviews, analysed thematically using a phenomenological approach.The limited qualitative sample was justified as appropriate for a pilot focused on instrument validation, with limitations due to access, ethics, and time constraints; future work will expand this sampling.The instruments were pre-tested for cultural and linguistic appropriateness through expert review and back-translation.Results: Survey constructs showed strong reliability (α = 0.87-0.93).All six hypotheses were statistically supported, validating the extended TAM framework.Path relationships were tested through SEM, supported by multiple regression, enhancing methodological robustness.Qualitative data prompted question wording changes and highlighted format preferences: parents preferred in-person interviews, providers preferred virtual.Implications: Findings confirm the instrument's reliability and support the extended TAM model.Additionally, these results provide actionable implications for the design and implementation of culturally tailored mHealth interventions.The extended TAM framework can guide developers and healthcare administrators in designing mobile health tools that incorporate elements of social influence and trust into app features, training programs, and communication strategies.These insights support the effective deployment and potential scaling of such technologies within conservative healthcare systems like Saudi Arabia.Moreover, the study explicitly aligned its findings with the four guiding research questions: perceived usefulness and ease of use (RQ1) and social influence (RQ2) significantly predicted adoption; system and information quality (RQ3) enhanced trust; and trust in reliability and data security (RQ4) mediated user acceptance, reinforcing the explanatory strength of the extended TAM in this context.Future studies are recommended to include participant stratification by oncologic treatment phase and implement pre-and post-intervention pain assessments to isolate effects and enhance clinical interpretability.

| 2025 | AraXLM: Evaluating Arabic Diacritization Tools for Cross-Language Plagiarism DetectionabstractIn recent years, plagiarism detection systems have evolved from basic lexical matching and n-gram overlap methods to Deep Learning (DL) models capable of capturing semantic relationships between texts. While these DL-based approaches have achieved notable success across various languages, their effectiveness in Arabic remains limited due to inherent linguistic ambiguities, particularly the omission of diacritical marks. This absence hinders accurate semantic interpretation and limits the ability of models to detect paraphrased or semantically obfuscated content in Arabic texts. This paper presents an evaluation of Arabic Text Diacritization (ATD) tools as the initial phase of a plagiarism detection framework designed for Arabic–English cross-lingual model text analysis (AraXLM). It describes the first stage of the framework, which focuses on assessing the performance of state-of-the-art ATD tools. An empirical analysis was conducted on six ATD models using Word Error Rate (WER), Diacritic Error Rate (DER), both with and without case endings (CE), and Bilingual Evaluation Understudy (BLEU) metrics. The results show that tools such as Shakkelha produced lower DER and high BLEU values, indicating high accuracy in diacritic restoration, while Fine-Tashkeel demonstrates the lowest WER and highest BLEU, reflecting best word-level performance. In contrast, CAMeL Tools and Mishkal display comparatively higher error rates across both metrics. These findings suggest that incorporating accurate diacritization models into Arabic NLP tasks, such as Machine Translation (MT) and Plagiarism Detection (PD), improves text normalisation and the quality of semantic embeddings. Thus, the AraXLM framework, supported by effective diacritization pre-processing, enhances linguistically aware detection of plagiarism involving Arabic text, where precise semantic alignment between languages is essential.

| 2025 | CADM: An LSTM-Based Model for Detecting Creative Accounting in Time-Series Data from Saudi-Listed CompaniesabstractStudies on Saudi accounting practices have identified evidence of creative accounting in the financial statements of listed companies.Despite the application of various fraud detection methods, identifying legal but misleading manipulations remains challenging.This paper extends the Creative Accounting Detection Model (CADM), an LSTM-based model originally proposed by Bineid et al. (2023, 2024) for detecting creative accounting.Two versions, (CADM1) and (CADM2), were trained on two simulated datasets with different bases, achieving 100% and 95% accuracy, respectively.Testing on the energy sector (2019-2023), CADM1 identified one company as engaging in creative accounting, while CADM2 classified all companies as non-creative with greater confidence stability.The findings establish CADM as a robust, scalable solution for the early detection of financial manipulation.By combining predictive strength with explainability, CADM can be employed to advance current approaches to forensic accounting and risk analytics, offering valuable insights to regulators, auditors, and decision-makers.

| 2015 | Exploring determinants of adoption and higher utilisation for e-Government: A study from business sector perspective in Saudi ArabiaabstractProviding e-Government services to business sector is a fundamental mission of governmental agencies in Saudi Arabia. The adoption of e-Government systems is less than satisfactory in many countries, particularly in developing countries.One pertinent, unanswered question is what are the key factors that influence the adoption and utilisation level of users from business sector. This paper utilised e-Government Adoption and Utilisation Model (EGAUM) proposed in our previous work in order to analyse determinants of higher level of e-Government adoption and usage. The study involved 48 participating business entities from two major cities in Saudi Arabia, Riyadh and Jeddah. The descriptive analysis is presented in this paper and the results indicated that all the proposed factors have degree of influence on the adoption and utilisation level. Perceived Benefits, Functional Quality of Service, Previous Experience, Perceived Simplicity, Accessibility and Regulations & Policies factors were found to be the significant factors that are most likely to influence the adoption and usage level of users from business sector.

| 2014 | Towards a Comprehensive Model for E-Government Adoption and Utilisation Analysis: The Case of Saudi ArabiaabstractAbstract—E-Government increases transparency and improves communication between the government and the users. However, users ’ adoption and usage is less than satisfactory in many coun-tries, particularly in developing countries. This is a significant factor that can lead to e-Government failure and, therefore, to the waste of budget and effort. Unlike much research in the literature that has utilised common technology acceptance models and theories to analyse the adoption of e-Government, which may not be applicable for e-Government acceptance analysis, this study proposes a more comprehensive and appropriate framework for analysing the significant factors that could influence the adoption and utilisation of e-Government in Saudi Arabia, as this is becoming a necessity.

| 2014 | Exploiting the potential of large databases of electronic health records for research using rapid search algorithms and an intuitive query interfaceabstractOBJECTIVE: UK primary care databases, which contain diagnostic, demographic and prescribing information for millions of patients geographically representative of the UK, represent a significant resource for health services and clinical research. They can be used to identify patients with a specified disease or condition (phenotyping) and to investigate patterns of diagnosis and symptoms. Currently, extracting such information manually is time-consuming and requires considerable expertise. In order to exploit more fully the potential of these large and complex databases, our interdisciplinary team developed generic methods allowing access to different types of user. MATERIALS AND METHODS: Using the Clinical Practice Research Datalink database, we have developed an online user-focused system (TrialViz), which enables users interactively to select suitable medical general practices based on two criteria: suitability of the patient base for the intended study (phenotyping) and measures of data quality. RESULTS: An end-to-end system, underpinned by an innovative search algorithm, allows the user to extract information in near real-time via an intuitive query interface and to explore this information using interactive visualization tools. A usability evaluation of this system produced positive results. DISCUSSION: We present the challenges and results in the development of TrialViz and our plans for its extension for wider applications of clinical research. CONCLUSIONS: Our fast search algorithms and simple query algorithms represent a significant advance for users of clinical research databases.
