    Sri Lankan SMEs’ Performance Through Cloud Computing Adoption: An SEM-ANN Analysis

    by Samsudeen Sabraz Nawaz, Samantha Thelijjagoda

    This study identifies the determinants of cloud computing adoption and its effect on the performance of Sri Lankan small and medium-sized enterprises (SMEs). The Technology-Organization-Environment (TOE) framework, Technology Acceptance Model (TAM), and individual context were used to derive the study variables. This quantitative cross-sectional study adopted items from previous validated studies. Google Form was employed to collect data, and 418 responses were received from Sri Lankan SMEs. Partial Least Squares Structural Equation Modelling (PLS-SEM) via SmartPLS 4 and Artificial Neural Network (ANN) analysis via IBM SPSS 29 were used for data analysis. Based on the results, all hypotheses are confirmed except for one, and SME performance is significantly affected by cloud computing adoption. This study adds to the existing empirical evidence on cloud computing adoption by introducing an all-inclusive model that integrates the TOE, TAM, and individual factors. This demonstrates the effectiveness of the PLS-SEM/ANN hybrid methodology in analysing the determinants of cloud computing adoption. The significance of top management as a factor is highlighted by providing training and education to employees. Managers can benefit from this result by improving cloud computing adoption among SMEs in Sri Lanka. This is the first study of its kind in Sri Lanka, integrating the TOE, TAM, and individual variables and using a hybrid methodology combining PLS-SEM and ANN.

    Managing the RFP Process of Government ICT Projects from a Discursive Perspective

    by W. Tilak R. De Silva, T. A. S. S. Thelijjagoda

    E-government projects which utilize Information and Communication Technology (ICT) to enhance public service delivery and improve governmental efficiency, hold significant promise. However, the success rate of these initiatives, particularly in developing countries such as Sri Lanka, remains alarmingly low. A key factor contributing to this high failure rate is the inadequacy of the Request for Proposal (RFP) process, which often results in budget overruns and project delays due to incomplete or inaccurate requirements. This research explores the pivotal role of RFPs in the successful implementation of e-government projects. Using a mixed-method approach, the study incorporates three case studies, and a Likert scale questionnaire prepared based on case study outcomes. The data for quantitative analysis was collected from questionnaires and quantitative data analysis was done using SPSS software. The findings from data highlight the critical importance of a well-crafted RFP in mitigating budgetary issues and ensuring precise requirement specifications. The study culminates in the development of ten practical guidelines aimed at enhancing the RFP preparation process, thereby increasing the likelihood of success for future e-government projects. Adopting these guidelines will enable government organizations to prepare more effective RFPs, contributing significantly to the overall success of their projects. While the guidelines are broadly applicable, slight adjustments may be necessary depending on the specific nature of the project. These guidelines offer valuable insights for both industry professionals and policymakers in the e-government sector.

    Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder that affects children. Identifying children with ADHD is a challenging task, as it requires specialized training and expertise. A novel approach to identifying children with ADHD using artificial neural networks (ANNs) and convolutional neural networks (CNNs) was proposed in this research paper. The web application “NEUROASSIST ADHD Analyzer” was developed to assist in the identification of children with attention deficit hyperactivity disorder (ADHD) using electroencephalogram (EEG) and facial expression data. The application includes three focus games, focus activities, a facial expression analyzer, a combined probability predictor, and a BOT application for the SNAP IV questionnaire. The ANN and CNN models were used to implement these components. An LR model was used to predict the overall result. The integration of these multiple models into the combined model resulted in an accuracy of 94%, with a sensitivity of 90% and a specificity of 92%. Additionally, the area under the receiver operating characteristic curve (AUC-ROC) was 0.91, indicating good discriminative power. Furthermore, a user study indicated that the application is user-friendly and effective in assisting with the diagnosis of ADHD. This research demonstrates the potential of ANNs and CNNs in identifying children with ADHD and presents a promising tool for assisting clinicians in diagnosing the disorder. Future work could focus on improving the accuracy of the models by incorporating additional data sources and features and expanding the application to a larger population.
