Item A Conceptual Framework on IT Governance Impact on Organizational Performance: A Dynamic Capability Perspective(Richtmann Publishing Ltd, 2021-01-17) Harguem, SaidaRecent years have seen substantial growth in Information Technology Governance (ITG) research. However, the influence of ITG on organizational performance has been less covered and very little theorized. To address this gap, the purpose of this paper is to build a conceptual framework to provide a better understanding of ITG contribution to organizational performance. Based on an extensive literature review on ITG and guided by the dynamic capabilities perspective, the proposed conceptual framework analyses the ITG – Organizational Performance relationship through the lenses of the dynamic capability perspective and generate a set of five research propositions. The proposed framework suggests that the effectiveness of ITG mechanisms (structures, processes, and relational mechanisms), contribute to the development of a dynamic ITG competence which has an impact on the development of IT management capabilities and their evolution. Moreover, the proposed conceptual framework suggests that ITG is more likely to lead to better organizational performance when IT management capabilities are developed in line with business strategy. © 2021 Saida Harguem.Item Designing an MI-PCA based Agile Intrusion Detection System(Institute of Electrical and Electronics Engineers Inc., 2022) Kaushik, Sunil; Bhadrdwaj, Akashdeep; Rehman, Ateeq Ur; Bharany, Salil; Harguem, Saida; Kukunuru, Saigeeta; Thawabeh, Ossma AliItem Enterprise resource planning implementation within science and technology park (STP) organisations: an avenue for future research. A systematic review.(F1000 Research Ltd, 2023) Harun, Sharbani; Dorasamy, Magiswary; Bin Ahmad, Abdul Aziz; Yap, Ching Seng; Harguem, SaidaBackground: Enterprise resource planning (ERP) is critical to enhancing the ability to control commercial activities and results in a competitive advantage when combined with an organisation's existing competitive advantages. However, our practise review reveals that end users resist ERP implementation because the resulting changes will alter the current status quo. The implementation of an ERP system in an organisation is complex as it affects multiple areas of the business. Resistance to change is cited as a factor of ERP failure. Methods: In this study, we conducted a systematic literature review using Transfield’s five stages and established a conceptual framework for ERP system implementation in science and technology parks (STPs). Articles collected from Emerald, Science Direct, ProQuest and Scopus databases between 1 st June 2021 and 15 th June 2021. Two authors were assigned to check the suitability of the articles in order to avoid risk of bias. Articles were analysed based on components of a research paper and the data was tabulated using MS Excel. Results: Only eight papers (0.011% of all the papers) appeared when we searched for papers related to ERP with a focus on post ERP Implementation, end-user behaviours, organisational performance, and the accelerated SAP (system application and product) methodology. We found that there are hardly any articles on ERP post implementations in STP context particularly based on the evaluation part of accelerated SAP. Conclusions: Results indicate the lack of studies in this field, particularly those addressing issues related to STP. This study attempted to broaden the understanding of the ERP's effectiveness, particularly in terms of an organisation's operational performance.

IT strategic importance has prompted many organizations to extend Governance to IT and place it high on their agendas. Banks are among those organizations that heavily use IT to enhance their service delivery capabilities. Besides, globalization, competition, and compliance requirements pushed banks to consider IT Governance as part of their overall corporate governance strategy. Past studies have shown that IT Governance in the financial industry is more mature than in other sectors. However, there is little information about IT Governance in economically developing nations. This article conducted a Delphi study to evaluate the Perceived Efficiency and Ease of Implementation of IT Governance practices in the Tunisian banking industry. The results show that compared with Process and Relational Mechanisms, Structural Practices are perceived to be more effective and easier to implement. This research helps to understand better the current state of IT Governance Implementation in less developed countries. © 2022 Harguem et al.Item Machine Learning Based Prediction of Stock Exchange on NASDAQ 100: A Twitter Mining Approach(Institute of Electrical and Electronics Engineers Inc., 2022) Harguem, Saida; Chabani, Zakariya; Noaman, Samar; Amjad, Muhammad; Alvi, Muhammad Bux; Asif, Muhammad; Mehmood, Muhammad Hassaan; Al-Kassem, Amer HaniItem OMCOKE: A Machine Learning Outlier-based Overlapping Clustering Technique for Multi-Label Data Analysis(Slovene Society Informatika, 2022-11) Baadel, Said; Thabtah, Fadi; Lu, Joan; Harguem, SaidaClustering is one of the challenging machine learning techniques due to its unsupervised learning nature. While many clustering algorithms constrain objects to single clusters, K-means overlapping partitioning clustering methods assign objects to multiple clusters by relaxing the constraints and allowing objects to belong to more than one cluster to better fit hidden structures in the data. However, when datasets contain outliers, they can significantly influence the mean distance of the data objects to their respective clusters, which is a drawback. Therefore, most researchers address this problem by simply removing the outliers. This can be problematic especially in applications such as fraud detection or cybersecurity attacks risk analysis. In this study, an alternative solution to this problem is proposed that captures outliers and stores them on-the-fly within a new cluster, instead of discarding. The new algorithm is named Outlier-based Multi-Cluster Overlapping K-Means Extension (OMCOKE). Empirical results on real-life multi-label datasets were derived to compare OMCOKE’s performance with other common overlapping clustering techniques. The results show that OMCOKE produced a better precision rate compared to the considered clustering algorithms. This method can benefit various stakeholders as these outliers could have real-life applications in cybersecurity, fraud detection, and the anti-phishing of websites. © 2022 Slovene Society Informatika.
