Existing reinforcement learning (RL) studies typically adopt fixed-reward designs, which limit their adaptability in non-stationary markets. To address this gap, this paper proposes a RL framework, variational mode decomposition-proximal policy optimization (VMD-PPO), that integrates VMD with PPO. The framework leverages VMD to extract multi-scale market signals, employs PPO to optimize trading policies, and introduces a market-state-adaptive reward mechanism that dynamically balances return, risk, and transaction costs, overcoming the rigidity of static rewards in prior research. An empirical study centered on portfolio construction demonstrates that the VMD-PPO framework achieves superior performance across key metrics, including returns, maximum drawdown, and risk-adjusted returns, while consistently exhibiting strong robustness under various market trends. Unlike prior research, which primarily focuses on prediction accuracy, this study emphasizes adaptability and deployability, providing both a foundation and a practical pathway for applying RL to highly volatile financial assets.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"9 3","pages":"Article 100178"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149050814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on Elinor Ostrom's theory of the commons, reconceptualized for digital infrastructures, the analysis investigates how inadequate institutional arrangements contributed to the platform's premature discontinuation. A qualitative single-case design was employed, combining ten semi-structured expert interviews with an extensive documentary analysis, informed by informal discussions that provided contextual background. Data were coded through a three-phase iterative thematic process guided by Ostrom's design principles. The analysis identifies five interrelated governance shortcomings: excessive centralization of authority, limited procedural transparency and monitoring, rigidity of rules, limited small business involvement, and communication problems. These shortcomings eroded stakeholder trust and progressively undermined the platform's institutional viability. The study develops a conceptual model of governance breakdown in blockchain ecosystems and derives theoretical propositions regarding the institutional conditions for sustaining blockchain-based digital commons. By extending Ostrom's framework to blockchain-based infrastructures, this research contributes to the literature on decentralized governance and provides empirically grounded insights into the institutional design and governance of blockchain consortia.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"9 3","pages":"Article 100193"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148952650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings highlight SI as a significant partial mediator of DT’s impact on SSCP, with mediation effects occurring primarily through service process innovation, while service product innovation exhibits a statistically significant but economically very small mediating effect, whereas the mediating effect of service model innovation is negative but statistically non-significant. By identifying SI as a novel mediating mechanism, this study adds to the expanding body of research on DT and SSCP, offering both theoretical and actionable insights.

Findings indicate that DE significantly promotes HQDF through three key implementation mechanisms rooted in digital-real integration: technological breakthroughs, factor reallocation, and industrial transformation and upgrading. Compared with the equity dimension, DE shows larger estimated coefficients for the efficiency and sustainability dimensions of HQDF. Heterogeneity analysis shows that this effect is more pronounced in state-owned firms, non-high-tech firms, and regions with a high degree of digital-real integration (i.e., eastern and central China). Additionally, the positive role of DE in promoting HQDF is strengthened through improved intellectual property protection and digital infrastructure construction.

Amid the global energy crisis, precise hydropower forecasting is becoming increasingly crucial, providing governments with a vital foundation for devising energy strategies and supporting the transition to a stable, clean energy future. Although previously applied methods for predicting hydropower generation have achieved commendable results, it is difficult for them to capture the significant seasonality and inherent uncertainty of hydropower generation, and they tend to overlook the importance of internal explainability in forecasting models. An innovative and explainable hydropower generation prediction model consisting of a two-stage decomposition method for input data processing, polar lights optimization (PLO) for hyperparameter optimization, and a temporal fusion transformer (TFT) is employed to address the above limitations. First, a series of subsequences is adaptively obtained using a two-stage decomposition strategy, allowing for a more thorough exploration of the inherent wave characteristics of complex short-term hydroelectric power generation sequences. Subsequently, polar lights optimization was utilized to intelligently and effectively optimize the parameters in the TFT model, guaranteeing the steadfastness and dependability of the prognostic structure. The empirical results indicate that the proposed model exhibits good predictive performance on the evaluated test sets in short-term hydropower forecasting datasets. By exploring the interpretation of hydropower forecasting results, decision-makers can gain a better understanding of future hydropower production capacity, thereby optimizing resource allocation, managing risks, and ensuring the stability of electricity supply.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"9 3","pages":"Article 100191"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149153333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This literature review analyzed 95 peer-reviewed publications published between 2017 and 2025 across six domains: education, healthcare, tourism and cultural heritage, business and marketing, the metaverse, and others (e.g., review papers). The findings revealed that immersive applications could significantly enhance engagement, empathy, and learning effectiveness; however, they frequently induce cognitive overload, privacy risks, and unequal access. In education and healthcare, immersive technologies offer substantial benefits for training and rehabilitation but remain challenged by fatigue, ethical safeguards, and technological dependence. Tourism and cultural heritage research has highlighted that immersive storytelling fosters empathy and preservation, but long-term inclusivity and sustainability are limited. In business and marketing, XR-enabled experiences strengthened trust and consumer–brand relationships, but increased user exhaustion and exclusion. Furthermore, metaverse research has underscored the importance of social presence, identity formation, and collaboration, while revealing persistent governance and accessibility gaps. Synthesizing across these domains, the review identifies four crosscutting challenges: (1) emotional polarization, (2) cognitive and ethical fatigue, (3) design-context misalignment, and (4) socioeconomic inequities. From a sociotechnical perspective, these tensions illustrate how immersive technologies empower and exhaust users.

Real-world investors attempt to select a portfolio based on their preferences for each objective and their decision-making behaviors. Moreover, integrating investor behavior according to predicted future stock market trends results in more appropriate portfolios. To address such situations, we propose a multi-objective approach for modeling investors’ preferences regarding several objectives (portfolio return, risk, and beta) as well as their decision behaviors in relation to future market scenarios. Additionally, real-world features such as cardinality and diversification constraints were considered. This study proposes a novel behavior-based nonlinear goal programming model for PS that aligns with stock market trends. The concept of behavioral functions is introduced to model investors’ decisions in the portfolio optimization process. To clarify the effects of different risk attitudes on PS, we examined three commonly used types of risk: risk-averse, risk-neutral, and risk-seeking. Our approach is validated using the S&amp;P 100, where three distinct investment scenarios (sideways, upward, and downward moving market trends) are analyzed separately. The proposed PS models are then applied to determine the best portfolios, demonstrating their effectiveness in formulating and integrating investor preferences and behaviors.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"9 2","pages":"Article 100168"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148527434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
