Up to 78% of oil and gas megaprojects fail to deliver on initial commitments, yet maintenance readiness is routinely deferred until after construction decisions are already irreversible. This study investigates the previously unexamined link between maintenance readiness and interface management across the capital-project life cycle through a systematic literature review combined with a 30-year longitudinal analysis of 941 anonymised interface lessons-learned records spanning 21 countries. Root causes were classified using ISO 14224 of 2016, and predictive models were validated through stratified coding (Cohen's κ = 0.81) and five-fold cross-validation. The analysis revealed that five root causes drove 81.2% of all failures, including slow interface identification (18.5%), uncertain technical definitions (17.4%), weak governance (17.4%), unclear scope and ownership (16.3%), and cross-discipline communication breakdowns (11.6%), with key effects being performance impact (41.8%) and schedule delay (25.7%), while 33.0% of records were classified as high or critical risk and approximately 40.3% originated in Front-End Engineering Design. The Interface Criticality Index (ICI) correlated strongly with high-risk classification (r = 0.83), and the Random Forest classifier achieved ROC-AUC = 0.848 and PR-AUC = 0.850 respectively. The findings conclude that maintenance readiness should be established as a distinct, front-end-loaded discipline rather than a post-handover activity, as embedding readiness controls upstream converts lessons-learned records from retrospective artefacts into proactive design constraints, enabling early intervention before costly lock-in.

This systematic review synthesizes 40 peer-reviewed studies to examine the role of inclusive finance and institutional governance in FinTech adoption in Pakistan's banking sector. While user-centric behavioural models are the dominant narrative in global discourse, this review highlights the underappreciated role of institutional trust, regulatory design, and structural inclusion in the scalability of FinTech ecosystems. The paper identifies four thematic clusters using PRISMA and TCCM frameworks, namely, user-level drivers, governance enablers, financial inclusion mechanisms, and integrated adoption frameworks. Findings suggest that inclusion should be reimagined not just as an objective but also as a prerequisite to digital finance, and quality of governance directly moderates trust and adoption behaviour. The study presents an original conceptual framework that links ecosystem-level conditions and adoption dynamics, highlighting the need for multi-level theoretical approaches that incorporate behavioural, institutional, and infrastructural dimensions. Implications are drawn for policymakers, FinTech innovators, and financial regulators who are looking for inclusive, trusted, and sustainable digital finance solutions in emerging markets.

This study contributes a data-driven roadmap for navigating this rapidly evolving field and identifies priority areas for future investigation.

Portfolio management has become a strategic activity in response to increasing organizational complexity, requiring models capable of reconciling multiple criteria, limited resources, and uncertainty. In this context, Portfolio Decision Analysis (PDA) has emerged as a well-established field within Operations Research dedicated to supporting such decision-making processes. This study presents a systematic literature review conducted in accordance with the PRISMA protocol, aiming to analyze the evolution of mathematical models applied to portfolio management. The search resulted in a final sample of 152 articles published between 1994 and 2025. The findings reveal a significant increase in publications from 2014 onward, with applications predominantly concentrated in project management and new product development (NPD), and a predominance of financial and technical-operational decision criteria. The results also indicate a methodological transition from classical optimization techniques to hybrid approaches that integrate multicriteria decision-making methods, fuzzy logic, mathematical programming, and, more recently, machine learning. The main research gaps identified include the need for broader empirical validation, the expansion of applications to different contexts, and the development of new hybrid approaches. This study provides an integrated overview of the methodological evolution of Portfolio Decision Analysis, offering a valuable reference for future research.

This study provides a comprehensive bibliometric analysis of 297 peer-reviewed articles From (2021–2025) about international student entrepreneurial objectives, with a focus on global cohorts and the digital economy. The primary objective is to map the field's intellectual structure, current trends, and research gaps while assessing how student psychological factors fit into macroeconomic frameworks such as the 13th Malaysia Plan and Malaysia's National Entrepreneurship Policy 2030 (DKN 2030). Using the keywords "entrepreneurial intention" and "international students”, the methodology systematically retrieved data from the Dimensions AI database in accordance with PRISMA 2020 requirements. This process reduced an initial pool of 22,248 records to a refined dataset that was assessed using VOSviewer. According to this bibliometric analysis, Malaysia and Indonesia dominate the world in production. Thematic clustering indicates that while the Theory of Planned Behavior (TPB) remains the essential theoretical framework, new research is emphasizing institutional support, psychological resilience, and digital revolution. The findings align with DKN 2030, suggesting that institutional integration is necessary to transform academic presence into long-term entrepreneurial engagement.

The topic of behavioral segmentation has emerged as an important research area in e-commerce since online stores increasingly depend on customer data for personalized, recommendation, retention, pricing, and marketing decisions. Behavioral segmentation is focused on observable actions such as browsing, clicking, buying, cart interaction, channel use, response to discounts, churn, and engagement. The existing studies are split across different methods, data sets, behavioral variables, and application areas making it difficult to understand the role that behavioral segmentation plays in e-commerce. The reviewed papers presented below are a systematic review of 44 studies in e-commerce behavioral segmentation published between 2016 and 2026. The selected papers were analyzed according to the selection process, inspired by the PRISMA framework. The selected papers were reviewed along with their segments, behavioral data sources, application areas, and limitations. Behavioral segmentation techniques are dominated by RFM-based models, clustering algorithms, and machine learning. Deep learning, explainable AI, dynamic segmentation, and recommendation models are starting to dominate. Most of these studies are based on transactional data while clickstream behavior, customer journey signals, omnichannel interactions, privacy-aware modeling, and real-time segmentation are understudied. From a managerial perspective, behavioral segmentation is connected to customer retention, personalized marketing, recommendation systems, churn prediction, estimation of customer value, and strategic decision making. This review summarizes the current state of behavioral segmentation in e-commerce and outlines some directions for future research toward more dynamic, explainable, ethical, and business performance-oriented customer analytics.
