Construction management, from the contractor’s perspective, is led by the Construction Manager (CM). The work motivation and leadership style of the CM are critical variables for the successful execution of construction projects. The scientific literature identifies participative leadership as the most effective style for mitigating conflicts among various stakeholders. However, analyzing the specific variables that influence a CM’s conflict resolution capacity remains an underexplored area. Furthermore, while the CM must act as a leader for their team (subcontractors, suppliers, etc.), they remain accountable to the contractor’s senior management. Therefore, this study aims to analyze the mediating role of CM motivation in the relationship between leadership and conflict resolution capacity using Partial Least Squares Structural Equation Modeling (PLS-SEM). In the construction industry, conflict resolution is not merely a situational fix but a critical process of capturing and externalizing tacit knowledge. Knowledge management and the ability to resolve conflicts in the construction sector are directly linked, critical, and strategic in nature. Construction is an industry characterized by fragmentation, the temporary nature of its projects, diversity of stakeholders (developers, builders, subcontractors, engineering firms) and a high level of uncertainty. In this environment, conflict is virtually inevitable. However, the way in which a CM handles a conflict determines whether it becomes a destructive dispute or an opportunity for improvement.

This article presents the late eighteenth-century origins of debates concerning the Christianization of the Romanians, focusing on the controversy between Franz Joseph Sulzer and the representatives of the Transylvanian School. It argues that this early dispute already formulated key interpretative models later developed in modern historiography. Rather than being limited to the issue of Roman continuity, the debate also addressed questions of ecclesiastical jurisdiction, ritual affiliation, and the influence of South-Danubian and Bulgarian Christianity. The study further examines the political use of Sulzer’s arguments in the context of the Supplex Libellus Valachorum, as well as the role of Petru Maior in transmitting and reshaping the controversy for the nineteenth century. By reassessing both the original texts and their later reception, the article highlights the need to reconsider the historiographical construction of Romanian Christianization narratives.

This study systematically explores the underlying mechanisms of collaborative innovation driving the green transformation of traditional energy enterprises. Existing research primarily focuses on enterprise scale and overall competitiveness, rarely delving into these specific collaborative pathways. Furthermore, studies employing evolutionary game theory to analyze the tripartite relationship among the government, traditional energy, and emerging technology enterprises remain fragmented, failing to fully capture the dynamic mechanisms of multi-stakeholder strategic choices. To bridge these gaps, this paper constructs a tripartite evolutionary game model incorporating coordination costs and the benefit distribution ratio to explore their influence mechanisms. Replicator dynamics equations are employed to identify stable cooperation conditions, overcoming traditional two-party framework constraints. Additionally, MATLAB R2024b numerical simulations validate the theoretical findings. The results reveal two evolutionarily stable equilibrium points. First, higher initial willingness among participants accelerates the system’s evolution toward a stable cooperative state. Second, coordination costs induced by information asymmetry act as a core bottleneck that deters participation and risks collaborative collapse. Third, targeted government incentives and a rational benefit distribution ratio directly determine cooperation willingness; notably, enterprises adopt collaborative strategies only when this ratio falls between 0.27 and 0.69. Fourth, fair and transparent supervision is crucial for mitigating trust deficits and distribution disputes. Ultimately, scientifically designing incentives, optimizing benefit structures, promoting information sharing, and establishing robust supervision effectively facilitate a sustainable tripartite collaborative innovation pattern.

In this research we analyzed land cover/use processes and their impact on biodiversity in the Megalopolis of Mexico City. We used land cover/use databases from 1976 and 2018, both validated, improved and adapted for conducting landscape dynamic analysis. We also included records of 159 threatened species of fungi, vascular plants and vertebrates to construct spatially explicit biodiversity richness models based upon niche ecological algorithms. The results showed that human settlement encroachment (35%, 1892 km²) was the main factor driving land cover/use changes, significantly affecting rural and natural landscapes. The extent and location of the dramatic shrinking of agricultural land was clearly demonstrated (47.22%). Afforestation was the second most important land cover/use process occurring mainly on conversion of native grasslands and shrubland into forest cover mainly with non-local tree species. Biodiversity richness was depleted substantially, affecting 36.7% of the largest hotspots by human settlement encroachment. On the mountain peaks, as vestiges of temperate Nearctic ecosystems, with a large number of endemic and threatened species, remnants of the high potential richness of biodiversity are still conserved. The results are discussed in the light of interdisciplinary methodological approaches, potential water recharge, governance of territorial disputes, loss of cultural heritage and poorly implemented environmental policies. Furthermore, the study highlights the urgent need to generate an innovative model for development which gives equal importance to the conservation of natural and rural landscapes as a fundamental form of subsistence for human settlements. Protecting biocultural heritage is of paramount importance. The region’s genetic resources and cultural diversity are unique and have played a fundamental role in providing various benefits from nature to urban and rural inhabitants. These findings can serve as a guide for other similar megacities around the world. Full article

Pre-made dishes have drawn growing attention because of their convenience and rapid market expansion. Their food safety risks, however, are shaped not only by products themselves, but also by the gap between public perception, reported incidents, and inspection records. This study develops a three-stage analytical approach by combining Weibo public opinion data, news media reports, and food inspection records from Gansu Province. First, ERNIE and BERTopic are used to identify public sentiment and discussion topics. The results show that negative sentiment slightly exceeds positive sentiment, with school meals, additives, and food safety as the main concerns. Second, 11,110 pre-made dish-related food safety reports from Food Partner Network are clustered and assessed for incident severity. The results point to drug residues in aquatic products, microbial contamination in egg products, authenticity disputes over meat ingredients, and quality issues in frozen composite foods. Third, based on the 2024 official definition, 12,121 inspection records are screened, and 2783 definition-constrained pre-made dish-associated products are retained. Six imbalanced classification models are then constructed. The Weight + RF model performs relatively well for starch and starch products, with a Precision of 0.7857, an AUC-ROC of 0.7778, and an MCC of 0.4429. The study provides a reference for risk identification and inspection resource optimization under limited pre-made dish inspection data. Full article

Most empirical research on drinking water governance and regional transformations in Bangladesh has focused on developed and urban regions. We focus on coastal rural areas to address this gap and employ a three-step methodology for the systematic analysis of the broader and site-specific drinking water landscape, involving (i) stakeholder analysis and mapping to identify key actors and characteristics, (ii) field work to identify case study sites, meet stakeholders and identify local water technologies, and (iii) in-depth analysis, triangulating stakeholders, drinking water technologies and governance structures, to identify synergies, differences, gaps and overlaps within them. Taking four different but illustrative case study areas in the Southwestern coastal region of Bangladesh, we identify key stakeholders and capture the multiplicity and dynamism of governance models. We provide the first in-depth mapping of the drinking water landscape in coastal rural Bangladesh. Results reveal a fragmented rural water governance landscape, marked by failed or non-functional technologies due to disputes, poor maintenance, high costs, and lack of accountability after project completion, leaving communities to seek alternative water resources for themselves. We argue that informal water provision currently needs to exist beyond well-known governance models due to system inefficiencies and short legacies of implemented technologies. As the water deficit is predicted to increase, it is imperative to identify the complexities and inefficiencies in governance structures to construct collaborative, sustainable approaches to ensuring drinking water security.

Numerous safety hazards in construction projects can readily cause safety accidents. While collaborative governance among stakeholders is vital for construction safety, it is hampered by interest-related factors. Evolutionary game theory is an excellent tool for analyzing participants’ behavioral decisions based on interest factors, and it is employed in this study to explore strategies for promoting collaborative governance. However, existing studies rarely mention the concept of collaborative governance of construction safety risks, seldom focus on construction payment disputes between owners and contractors, and barely take into account the differences in interests and decisions faced by stakeholders under projects of varying costs. Based on this, an evolutionary game model among the government, owner and contractor is established by taking China’s construction industry as an example, and MATLAB numerical simulation is conducted. First, the heterogeneity of the laws of strategy evolution under different cost levels was verified. Subsequently, cost levels were divided into two major categories and four subcategories based on strategy evolution results, and sensitivity analysis was conducted for each corresponding scenario. It was found that rewards for owners and contractors are barely effective, while cutting government regulatory costs and boosting positive governmental incentives generally play a positive role. The effects of penalties for inadequate safety investment and safety accidents on collaboration differ across project costs. Nevertheless, collaborative governance can be achieved via reasonable parameter optimization. This study addresses the critical issue of interest factors hindering collaborative governance, and provides a critical perspective for promoting construction safety and the sustainability of the construction industry. Cost-stratified analysis reduces overly definitive suggestions, offering valuable insights for both theory and practice. Full article

In the social media era, “trial by media” has evolved into widespread public participation in “trial by public opinion,” posing complex challenges to procedural justice. Existing research often focuses on macro-theory or linear effects, lacking exploration into the meso-level mechanisms of how multiple conditions combine. To address this gap, this study employs fuzzy-set Qualitative Comparative Analysis (fsQCA) to systematically examine how nine antecedent conditions—including case attributes, dissemination features, and socio-emotional structures—combine to trigger trial by public opinion, based on 22 high-profile Chinese judicial cases from 2014 to 2025. The findings reveal no single necessary condition but five sufficient causal paths, which converge into three core configurations: the “Collective Moral Outrage” configuration (triggered by heinous crimes), the “Reactive Confrontation” configuration (arising from public power disputes), and the “Collective Speculation” configuration (catalyzed by factual ambiguity). Moving beyond the binary debate of “whether influence occurs,” this study constructs a configurational theoretical framework that elucidates the heterogeneous pathways and underlying socio-psychological dynamics behind the formation of public opinion trials. The conclusions provide empirical and theoretical insights for developing precise judicial communication, public guidance, and governance strategies tailored to different risk types in the digital age.

Construction projects are prone to conflicts and disputes due to differing stakeholder interests, which can adversely affect their successful completion in terms of time, cost, and quality. Thus, implementing effective conflict management methods is essential to reduce negative outcomes and capitalize on the positive outcomes of conflicts. However, there is still limited understanding of the status and trends of stakeholder conflicts, and critical conflict causes and management strategies identified by previous studies. Thus, a systematic literature review was conducted, complemented by a scientometric analysis using the VOSviewer bibliographic tool and Pareto analysis to systematically identify critical factors within literature. A total of 63 studies published between 1993 and 2025 were analyzed. Findings indicate that most recent studies have focused more on human, contractual, and technological aspects of conflict. Overall, this study identified 46 conflict causes and 58 management strategies, which were categorized into different groups based on their characteristics. Among these, 23 and 31 were identified as most critical causes and management strategies based on Pareto analysis, with most factors linked to stakeholder relationships. The study offers a systematic understanding of the status quo and emerging themes in stakeholder conflicts research in construction industry. The findings of this study will be beneficial for researchers in identifying future research directions and project stakeholders to understand the most common conflicts and effective management methods for handling conflicts in construction projects.

Although the expected future impacts of climate change on the construction sector are significant and commonly accepted, the prospect and viability of contractual solutions to mitigate such effects lack investigation. Scenario planning enables leaders to prepare for the future by revealing the impending opportunities and threats to businesses and markets. This article offers analysis, synthesis, and evaluation of published literature and results from a scenario-planning workshop. The study reveals that climate change and profit margins are the main forces that will impact the construction sector in 2030. Evidential materials, contract provisions, and data repositories involving existing and emerging technologies are the three tenets of an innovative conceptual solution that can reduce delay and disruption disputes. This is significant because, inter alia, as the consequences of climate change are likely to increase, contract terms that allocate risks associated with it are likely to be modified, and insurance companies are liable to increase indemnification premiums, or become unable to cover such risks. The offered solution, namely the Trilateral Model, increases the sustainability of construction contracting in this context through a clear, impartial, acceptable, and effective risk allocation mechanism that mitigates the impact of those forces and offers contractual certainty.

This is a preliminary report on a study of Indic precedents for Pure Land traditions. It contests anglophone scholarship that find those traditions to be predominantly East Asian constructions in discontinuity with Indian Buddhism. The first part, related to previously unpublished research, disputes a common leading point of such arguments that the expression pure land, jingtu, has no Sanskrit antecedents. The article will show that Sanskrit antecedents for jingtu are in fact abundant. The second part summarizes previously published work showing that the cosmology, soteriology, and buddhology of buddhakṣetras have explicit foundations among the heavens and devas. The third part forecasts research for Kenneth Tanaka’s “Other Power” project. ‘Other-power’ has been seen as discordant with Indian traditions, when even abhidharma sources state that, through ‘a single mind of faith in Buddha to the marrow of one’s bones, one can overcome infinite bad karma.’ The salvific power of the names of buddhas is a common concept in Indian Buddhism, declared even by Nāgārjuna. Not discounting Chinese and Japanese creative contributions and acculturation, Pure Land traditions are in strong natural continuity with Indian Buddhist thought. Full article

Carnation is one of the most popular ornamental flowers worldwide. Due to its high ornamental and economic value, breeding techniques have advanced rapidly, leading to the continuous emergence of new varieties. However, this has also resulted in issues such as synonymy and homonymy. Therefore, utilizing DNA fingerprinting for rapid and accurate variety identification can play a crucial role in germplasm identification and the resolution of intellectual property disputes. In this study, we performed reduced-representation genome sequencing on 50 carnation accessions to develop single nucleotide polymorphism (SNP) markers. After filtering, 82,584 high-quality SNPs were obtained. These SNPs were used to conduct principal component analysis, population structure analysis, and cluster analysis on the 50 carnation accessions. From these high-quality SNPs, 130 SNP loci were further selected and converted into Kompetitive Allele-Specific PCR (KASP) markers. Preliminary screening using 92 carnation accessions yielded 53 KASP markers, and a subsequent screening with 217 carnation accessions identified 45 core KASP markers. Using these core markers, a fingerprint database was successfully constructed for 309 carnation accessions, achieving a distinguishing power of 99.987%. This study employed SNP fingerprinting and genetic analysis for the screening and identification of carnations, broadening the genetic basis at the molecular level and supporting subsequent variety protection efforts, thereby providing a scientific basis for carnation selection and identification.

Construction disputes remain a major barrier to project success, particularly in international contexts characterized by diverse stakeholder expectations and high uncertainty. Although numerous studies have examined dispute causes, existing research is frequently limited by regional focus, phase-specific analysis, or delivery-method constraints. This study addresses these limitations by developing a lifecycle-based understanding of dispute causation through a semi-automated systematic literature review. A total of 6603 records were retrieved from Scopus and Web of Science, and after applying PRISMA-aligned screening and citation tracking, 52 peer-reviewed articles published between 2000 and 2024 were included. Bibliometric analysis was used to map publication trends, geographic distribution, journal contribution, and keyword networks, while content analysis supported the identification and consolidation of dispute causes across lifecycle phases. The results show that early project stages are dominated by unfair risk allocation, ambiguous contract documents, design errors, and unclear technical specifications, whereas the Execution phase is driven by variation orders, payment delays, ineffective communication, and unforeseen site conditions. Disputes in the Close-out phase remain underexplored, indicating a clear research gap. By linking dispute causes to specific lifecycle stages, the study provides a structured foundation for proactive dispute-prevention strategies and supports more effective management of construction projects worldwide.

Disputes over delay assessments are costly, persistent, prevalent worldwide, often funded by taxpayers, and negatively impact productivity in the construction sector. The identified academic literature argues that the main causes of the escalation of disagreements over delay assessments from contract claims into disputes (or factors) are objective factors, particularly unavailability and/or inadequacy of relevant project data. However, those findings are not based on comprehensive investigations of all factors involved, employing research methodologies that rely upon real-life project data. This article contributes to the fulfilment of the aforementioned knowledge gap. Published literature and twenty-one case studies were evaluated to identify the factors. The research findings revealed that although data-related issues were often important factors, they were not the main and/or most frequently identified ones. Subjective factors, including manipulation of programme activity completion dates, reliance on biased assumptions when data is unavailable, misinterpretation of material records, and self-serving delay analysis, were the main factors. The findings suggest that the root cause of this issue is the exploitation of systemic flaws, including the unavailability of good/best practice guidance on assessing the impact of delays, deficient contract provisions, inadequate impartiality, divergent priority of interests, unexploited technologies, and the confidential nature of dispute resolution methods.

Traditional claim management relies heavily on manual analysis and expert judgment, resulting in inefficiencies, information omissions, and heightened risks of disputes. To address these challenges, this paper constructs a domain-specific ontology for construction engineering claims through a five-step process, organizing the relevant knowledge into five unified core classes. Based on this ontology, a knowledge graph is built and stored in Neo4j. The resulting knowledge graph-enhanced LLM question-answering system, evaluated using BLEU-4, BERT-Cosine similarity, ROUGE-1, and ROUGE-L metrics, demonstrates superior performance compared to both the base LLM and Vector RAG approaches. The results indicate that the proposed ontology effectively serves the purpose of knowledge sharing and reuse while providing practical support for construction claim management. Full article
