The framework integrates transformer-based neural language models (AraT5-base and AraGPT2-medium) with symbolic reasoning encoded in OWL-DL ontologies and SWRL rules to ensure linguistic fluency, narrative coherence, and cultural preservation. AI-Cinema introduces a three-tier architecture comprising a data layer, cultural embedding layer, and scenario generation layer. Central to its design is an attention-based cultural embedding mechanism leveraging ArabicVerbNet (12,500 culturally annotated verbs) and ArabicNameNet (3653 names with regional annotations), complemented by a mathematically grounded harmony function that dynamically balances neural generation with symbolic constraints. In experiments on 2740 Arabic narratives, AI-Cinema achieves a BLEU-4 score of 32.76 (± 0.6), representing a 5.0% relative improvement over AraBERT-Gen (p < 0.01, paired bootstrap test) and a 27.5 percentage point gain in cultural preservation metric (CPM) compared with MARBERT-Gen (82.3% vs. 54.8%). The framework maintains 92.3% dialectal accuracy across Modern Standard Arabic and six regional dialects, with explicit evaluation of code-switching scenarios. Expert evaluations by 30 Arabic literature scholars demonstrate strong interannotator agreement (Fleiss’ κ = 0.78, p < 0.001), with 87% of evaluators rating generated narratives as culturally authentic (score ≥ 4 on a 5-point scale). Current limitations include reduced performance on underrepresented dialects (Yemeni: 85.6% and Sudanese: 86.1%) and complex code-switching scenarios (76.3% for 3+ dialects). The framework incorporates transparent labeling mechanisms for AI-generated cultural content to address authenticity concerns.

Analyzing 12 major commodities through rolling windows of 20, 60, 120, and 240 days, we compare linear versus nonlinear transmission mechanisms across different market conditions. The results show that while GC captures persistent linear relationships with monotonically increasing detection rates, TE reveals complementary nonlinear dependencies following nonlinear patterns. During crisis periods, network density increases significantly, with the COVID-19 pandemic producing pronounced nonlinear effects where TE substantially exceeds GC. Energy commodities dominate linear channels, while agricultural commodities emerge as central nodes in nonlinear networks. Period-specific analysis reveals regime-dependent transmission: postcrisis periods return to linear relationships, while commodity-specific shocks activate different nonlinear pathways than systemic crises. The findings demonstrate that comprehensive commodity market analysis requires both methodologies to capture the full spectrum of information transmission mechanisms.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/5511110","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147564901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops and analyzes a climate-sensitive malaria transmission model that incorporates mosquito behavior, insecticide resistance, and vector–human ecological dynamics to identify optimal control strategies for the Kenyan context. The model’s well-posedness was established, the basic reproduction number (R0) computed using the next-generation matrix method, and the stability of equilibrium points assessed. Spatial analysis of R0 was performed using temperature and rainfall raster data to map transmission risk across Kenya under varying insecticide use scenarios. Results indicate that regions with climatic conditions favorable for vector survival, particularly parts of the Eastern and Western regions, experience higher transmission intensity. Simulations show that while insecticide use (deltamethrin or permethrin) substantially reduces malaria prevalence, resistance (δv = 0) results in R0 > 1 and sustained transmission. An optimal control problem incorporating personal protection, antimalarial treatment, and vaccination was formulated and solved using Pontryagin’s Maximum Principle. The most effective reduction in malaria prevalence was achieved when all three interventions were applied simultaneously, with infections declining to zero within 10 days. These findings highlight the importance of integrating vector behavior, climate variability, and resistance dynamics into malaria models and support the use of combined intervention strategies to enhance control efforts in Kenya.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/7988450","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its evolution is shaped by nonlinear feedbacks between institutional design, asset credibility, and market confidence. This study develops an agent-based simulation model to examine how the withdrawal pace of government guarantees and the entry timing of market-based guarantors jointly drive the dynamic transition of the IP securitization market. The model captures adaptive interactions among heterogeneous agents including governments, guarantors, firms, and investors under varying transition scenarios. Results show that gradual government withdrawal, synchronized with moderate to rapid market guarantor entry, generates stable market growth and effective risk containment. In contrast, premature withdrawal without sufficient institutional substitutes amplifies systemic risk, undermines investor participation, and stalls market expansion. Persistent government guarantees can stabilize early markets but may inhibit the endogenous emergence of market-based risk pricing. The analysis also investigates the role of collateral requirements, showing that strict pledge standards constrain downside risk yet are less effective than external guarantees when high-risk participants bypass collateralization. Loosening pledge rules enhances financing access but can degrade product quality if not supported by mature institutional safeguards. These findings highlight the importance of policy sequencing, adaptive risk controls, and coevolutionary design in fostering a resilient and self-sustaining IP securitization system.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/5511673","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147564480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates how punitive interventions can mitigate free-riding and enhance vaccination uptake under adaptive decision-making. We develop an integrated evolutionary epidemic framework that combines evolutionary game theory with Q-learning, where individuals update their vaccination strategies by weighing vaccination cost, infection risk, vaccine effectiveness, and penalties for noncompliance. The model incorporates spatial interactions on structured populations, allowing local learning feedback and epidemic spreading to coevolve dynamically. Analytical results and numerical simulations reveal that punitive measures reshape the reinforcement learning reward structure, progressively discouraging free-riding and promoting cooperative vaccination behavior over repeated seasons. Vaccination effectiveness is a critical determinant: punishment alone is insufficient under low efficacy, whereas moderate-to-high efficacy regimes enable punitive incentives to align individual learning with collective welfare. Spatial clustering emerges as vaccinated individuals form stable blocks that impede transmission, reducing epidemic size and preventing resurgence. Extending the analysis across multiple network topologies demonstrates that while punitive intervention is broadly effective, its system-level impact is strongly modulated by network structure through local reinforcement, hub-driven dynamics, and information propagation. These findings highlight the importance of integrating adaptive learning dynamics, network heterogeneity, and behaviorally informed incentives into epidemic modeling, offering practical guidance for designing robust and resilient vaccination policies that mitigate free-riding and strengthen population-level immunity.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/8500709","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This oversight can lead to an incomplete understanding of the network’s structure and its evolutionary patterns over time. To tackle this problem, this paper introduces an algorithm designed to uncover tightly knit communities within short time spans by leveraging the comprehensive information contained in time-series data. Our method employs a computational approach that slices the temporal network into meaningful segments, enabling the identification of transient yet highly cohesive communities. Furthermore, it gauges the level of cohesion within these communities, providing analysts with a valuable tool for understanding the network’s dynamic behavior. Through experimentation, we demonstrate the effectiveness of this algorithm in accurately capturing the evolving structures of temporal networks, thereby contributing to a deeper comprehension of complex network dynamics.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/5604982","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147562439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response, nations are increasingly aligning with blocs such as the SCO, BRICS, INSTC, and IMEEC to strengthen their resilience. This study asks How can countries identify reliable trade partners with stable openness? Are stable trade partners (STPs) always symmetric? Drawing on Trade Interdependence Theory, Exit Cost Models, and fuzzy logic, the study introduces the STP index—constructed from deviations in macroeconomic stability, political stability, and trade openness volatility. A lower STP score signals higher stability. We compute STPs for 122 countries from 2000 to 2023, using two specifications: one including and one excluding two major recession periods (the global financial crisis of 2007–2008 and the COVID-19 crisis of 2020–2021), with inflation serving as a proxy for macroeconomic volatility. Additionally, we examine STPs using 5-year windows from 2019 to 2023 and employ net barter terms of trade as an alternative volatility proxy. Crucially, the analysis reveals a paradox that STPs are not necessarily symmetric, addressing a gap in the trade literature and offering guidance for policymakers navigating global uncertainty.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/9635278","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such instances, firms disseminate misleading information to align with market preferences, thereby undermining market efficiency and eroding trust. This study develops an evolutionary game-theoretic model to examine the dynamic interactions between corporations and institutional investors. The results indicate that, in the absence of regulatory intervention, markets tend to reach suboptimal outcomes. Specifically, they may converge to an equilibrium characterized by low investor trust and elevated greenwashing risk, or exhibit cyclical patterns in which periods of increased trust are followed by greenwashing crises. Further analysis underscores the critical role of regulatory intervention in steering the market toward an optimal equilibrium, where corporations undertake substantive improvements and gain investor trust. The effectiveness of regulation is found to be contingent upon its intensity; regulation that is too weak lacks impact, while overly stringent measures may suppress market dynamism. Importantly, higher corporate profitability broadens the range within which regulation is effective. Within this optimal regulatory range, the long-term welfare of both corporations and investors can be enhanced, resulting in mutually beneficial outcomes. This study provides new insights into strategic choice dynamics, trust evolution, and regulatory intervention in ESG markets and offers theoretical guidance for regulatory policy design and decision-making by both corporations and investors.","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2026 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/5544315","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147288384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
