Introduction: Elasmobranchs play a vital role in marine food webs through top-down control and the structuring of ecosystem stability, yet more than one-third of species face extinction. The Maldives, a recognised Indian Ocean hotspot for shark and batoid diversity, designated its EEZ as a shark sanctuary in 2010, but multispecies elasmobranch occurrence patterns and environmental drivers remain poorly characterised in Lhaviyani Atoll in the central Maldives, which hosts two Important Shark and Ray Areas (ISRAs). Recreational SCUBA networks can turn routine dive activity into long-term conservation evidence, already informing nearly 10% of the western Indian Ocean ISRAs. Objective: To characterise spatiotemporal patterns of elasmobranch assemblages in Lhaviyani Atoll (2017–2024), quantify how environmental and geomorphic drivers shape relative abundance, diversity, and hotspots, and provide evidence for targeted elasmobranch conservation. Methodology: A seven-year opportunistic dive-log dataset of 12,732 SCUBA surveys and 142,994 elasmobranch records across 94 dive sites was analysed. Effort-standardised relative abundance and community metrics (Shannon diversity, Pielou’s evenness) were modelled against sea surface temperature (SST), salinity, dissolved oxygen, chlorophyll-a, zonal current velocity, substrate type, and reef geomorphology using generalised additive models (GAMs). Spatial analyses identified persistent northern-rim aggregation areas aligned with ISRAs. Results: Twenty-eight species (14 sharks, 14 batoids) were recorded, including 23 threatened on the IUCN Red List (4 Critically Endangered, 12 Endangered, 7 Vulnerable). Relative abundance and diversity peaked during the late southwest monsoon (August–September) and declined during the northeast monsoon (December–March). After 2021, diversity and evenness increased while overall abundance declined. Relative abundance was primarily driven by SST, salinity, and current velocity; for sharks, dissolved oxygen and chlorophyll-a were additionally significant, whereas batoid abundance was driven mainly by temperature, oxygen, and current velocity. Four persistent hotspots along the northern atoll rim were identified, with sharks concentrated along exposed slopes and channels, and batoids distributed broadly within lagoonal habitats. Conclusions: Long-term citizen science dive-log monitoring is cost-effective for elasmobranch conservation in remote tropical seascapes. These results show how dive-industry partnerships can inform conservation governance over a decade after sanctuary designation, supporting targeted, habitat-focused management as shark and batoid conservation frameworks continue to evolve.

Incorporation of carbon-11 radiotracers for positron emission tomography (PET) imaging requires close coordination between cyclotron operation, radiochemistry production, quality control, and clinical administration. A persistent challenge exists is the minimization of the carbon-12 isotopologue mass of the radiotracer, which reduces molar activity and can compromise PET image quality. This challenge can be particularly acute at facilities where cyclotron operation and carbon-11 radiochemistry are realized by separate organizations with distinct operational priorities. Here, we describe how the Radiochemistry Group at New York University Grossman School of Medicine and Siemens Healthineers have developed an integrated operational framework for consistent, high-quality carbon-11 production within an academic–industry partnership. Cyclotron target maintenance and conditioning protocols, remote chemistry module maintenance schedules, a validated radio-HPLC method (UV LOD = 0.9 µg/mL, UV LOQ = 3.0 µg/mL) for trending methyl iodide isotopologue mass, and structured inter-team communication protocols are presented in this manuscript. Quality analysis demonstrates molar activities consistently exceeding the recommended minimum of 40 GBq/µmol for reversibly binding radiotracers used in human PET studies. This work is intended as a practical resource for radiochemists, cyclotron engineers, and facility managers working to establish or improve institutional carbon-11 programs. Full article

Diagnostic imaging is central to clinical decision-making across many care pathways, yet the expertise needed to use these images well is unevenly distributed across health systems, with workforce limitations identified as a major barrier to equitable access, particularly in low- and middle-income countries. Digital education has emerged as one response to this gap, offering scalability, asynchronous and just-in-time access, and the cost-efficiency required for global deployment. This paper examines the digital education portfolio of the International Atomic Energy Agency’s Nuclear Medicine and Diagnostic Imaging Section, hosted mainly on the open-access Human Health Campus, which in 2025 recorded approximately 45,800 active users and 150,000 views across 159 countries. The portfolio combines structured e-learning courses, interactive webinars, virtual conference access through the Livestream programme, and a broader repository of publications, teaching cases, and reference resources, supported by an internal e-learning framework and learning management system infrastructure. Partnerships with international scientific societies further extend the reach of expert knowledge and professional exchange. The paper argues that these initiatives are best understood not as content delivery alone but as a coordinated strategy to support diagnostic quality at the level of the practising physician, extending access to expertise and strengthening the conditions for better practice, while remaining a complement to, rather than a substitute for, supervised clinical training.

Food waste remains a persistent sustainability challenge within independent restaurants, where operational pressures, cultural norms, and resource constraints limit systematic waste management. This study examines how an industry–academia partnership enabled the co-creation of food-waste reduction practices between hospitality students and sixteen independent restaurant operators in Wellington, New Zealand. Adopting the Participatory Action Research (PAR) approach, data were gathered through semi-structured interviews with operators and focus group discussions with hospitality students. Findings reveal that food wastage in the study units is shaped by time pressure, customer service expectations, tacit kitchen routines, and uncertainty in forecasting the demand. The study identifies three mechanisms—emotional disruption, shared reflection and experimentation—through which sustainability competencies become a part in professional identity. It offers theoretical grounded and practically actionable insights for industry–academia collaboration in resource-constrained hospitality environments. Full article

Open innovation has become a central framework for explaining how firms access, integrate, and exploit knowledge beyond organizational boundaries. However, the conditions shaping its adoption by small- and medium-sized enterprises remain insufficiently understood, particularly in Latin American contexts. This study examines the determinants of open innovation adoption in Colombian SMEs and develops an analytical model that integrates six explanatory dimensions: external partnership and cooperation, government support, rules and regulatory factors, market and customer factors, organizational and human resource factors, and technological factors. Empirically, the study combines an exploratory qualitative phase, based on semi-structured interviews with SME managers in Bogotá, D.C., with a quantitative phase using survey data from 319 SMEs operating in ISIC 6201 and 6202. The hypotheses were tested using partial least squares structural equation modeling. The results show that technological factors have the strongest direct association with open innovation adoption, followed by government support and external partnership and cooperation. Market and customer factors, as well as organizational and human resource factors, also exert positive and significant effects, whereas rules and regulatory factors do not show a significant direct effect. Additional analyses indicate that organizational and human resource factors partially mediate the relationship between technological factors and open innovation adoption, while a complementary moderation test does not support an interaction-based effect. These findings suggest that open innovation adoption in SMEs is technologically enabled, partially translated through organizational and human resource capabilities, and shaped by a configuration of relational, institutional, market-based, and internal conditions rather than by any single determinant.

As plant-based diets catalyze a global shift toward sustainable consumption, Chinese plant-based food firms are experiencing rapid growth and seeking to expand their international footprint. This study investigates the mechanisms underlying the internationalization performance of these firms by integrating the Technology–Organization–Environment (TOE) framework with a configurational perspective. We operationalize nine antecedents across three dimensions: the technological dimension (technological maturity, supply chain resilience, and digital transformation), the organizational dimension (food safety certification intensity, strategic partnership intensity, and talent acquisition intensity), and the environmental dimension (market adaptability, compliance and risk management, and product line breadth). Utilizing fuzzy-set qualitative comparative analysis (fsQCA) on a sample of N = 29 publicly listed Chinese plant-based firms, this research identifies three distinct equifinal pathways to superior internationalization performance. The first is the Collaboration-Compliance configuration (Organization–Environment-driven), which is primarily characterized by the synergy between strategic partnerships and regulatory risk management. The second is the Supply Chain-Compliance-Product Diversification configuration (Technology-Environment-driven), where international success is predicated on the interplay among supply chain resilience, institutional compliance, and product variety. The third is the Full-Factor Synergy configuration (Technology-Organization-Environment jointly driven), which emphasizes a holistic coupling of technological innovation, organizational coordination, and external institutional adaptation. By uncovering these complex causal mechanisms, this study moves beyond traditional linear analysis to reveal how diverse capability configurations can lead to equivalent internationalization outcomes. The findings provide actionable strategic guidance for firms navigating the global plant-based market and offer theoretical insights for policy frameworks supporting sustainable dietary transitions.

Healthcare facilities are among the most energy-intensive public infrastructures due to their continuous operations, complex systems, and critical service requirements. In this context, Energy Performance Contracts (EPCs) have gained increasing attention as a strategic tool for enhancing energy efficiency and sustainability in healthcare facilities. This paper investigates the potential and implementation of EPCs in the hospital sector, with a particular focus on their integration within Public–Private Partnership (PPP) frameworks. The study addresses that gap through a cross-case analysis of fourteen hospital EPC projects implemented in Italy, the United Kingdom, the Nordic countries and Central-Eastern Europe, mapping their technical scope against a three-family taxonomy (envelope, plant systems, regulation and monitoring) and benchmarking their energy and economic performance. All figures reported derive from project documentation and contractual monitoring records. The results show that envelope-led configurations deliver the deepest reductions in primary and final energy consumption (up to 50% on the baseline), while plant-side measures, and trigeneration in particular, generate the largest absolute CO₂ savings (from approximately 500 to 17,000 tCO₂eq/yr); lighting, and building management systems (BMS) retrofits, although ubiquitous, account for a 20–25% band when deployed in isolation. The findings reframe EPCs as a configurable contract for decarbonization in healthcare environments and offer practitioners a reading grid for scoping future hospital retrofits under this framework.

This study examines how entrepreneurial ecosystem constraints shape MSME resilience in the Jakarta–Bogor–Depok Indonesia corridor using a qualitative multiple-case design. Drawing on 20 MSME case reports across food and beverage, retail, services, and small-scale manufacturing, the study addresses two questions: (1) which ecosystem domains are the most binding constraints, and (2) how MSMEs convert ecosystem resources into resilience outcomes. The analysis shows that market pressure is the most universal constraint (20/20 cases), followed by digital-managerial support infrastructure gaps (18/20), supply chain volatility (13/20), and finance, human capital, and institutional constraints (each 12/20 cases). Cross-case evidence identifies four recurrent mechanisms: market pressure is managed through digital channel orchestration and customer engagement; capital constraints are managed through internal cash discipline and partnership-based financing; input volatility is managed through supplier diversification, local sourcing, and inventory control; and skill gaps are managed through internal training and process standardization. Building on these mechanisms, the study develops a threefold resilience typology: Adaptive Leaders, Operational Survivors, and Vulnerable Traditionalists. The main theoretical contribution is to show that MSME resilience is configurational and depends on inter-domain alignment rather than on isolated ecosystem components or entrepreneur-level grit alone. The practical contribution is a typology-based policy logic that prioritizes integrated intervention bundles, which are finance, digital capability, operations, supply chain, and managerial upgrading, over fragmented support programs.

Indigenous food systems are increasingly threatened by climate change, socio-economic transformations, and reduced access to traditional lands and resources, contributing to disproportionately high levels of food insecurity among Indigenous peoples. Despite growing recognition of Indigenous food systems within sustainability research, limited attention has been given to Indigenous food system governance across different contexts. This study examined: (1) how Indigenous food systems vary across continents; (2) the key characteristics of Indigenous food system governance; and (3) how these characteristics are expressed within Sri Lankan Vedda communities. A systematic literature review of 143 publications from Web of Science and Scopus was conducted alongside a multi-sited case study involving 114 semi-structured interviews across six Vedda communities in Sri Lanka. Findings revealed continental variations in food sourcing, food sources, food use, and harvesting practices. Eight interconnected governance characteristics were identified: co-management, leadership, participatory research, partnerships, social networks, mutualism, collective action, and religious/cultural dimensions. Evidence from Sri Lankan Vedda communities demonstrated that strong leadership, social cohesion, and collaborative partnerships enhanced food security and resilience, whereas weakened governance structures and limited external support contributed to food insecurity. The study highlights the importance of strengthening Indigenous self-governance to support sustainable Indigenous food systems. Full article

Post-war Aleppo is often framed through destruction, legal constraints, and the technical demands of reconstruction. This article challenges that assumption by re-reading Aleppo’s pre-2011 municipal vision as an analytical resource for post-war recovery. The study adopts a qualitative interpretive methodology based on municipal archival material, including the City Council work programme, strategic planning presentations, project documents, and materials related to the City Development Strategy, Madinatuna initiative, the old city, Bab Antakiya, and major public-space and service initiatives. The analysis followed three steps: identifying repeated municipal priorities and planning concepts; organizing them into thematic axes; and interpreting flagship projects as spatial expressions of a broader municipal vision. To assess post-war relevance, the archive is also read against evidence of damage, displacement, urban functionality, and heritage loss. The results show that Aleppo’s pre-2011 municipal vision can be reconstructed through six interrelated axes: strategic urban development and managed growth; the old city as a living urban fabric; urban repair in the city centre; mobility and accessibility; culture and social development; and development partnerships and international cooperation. The findings reveal that these axes formed a partially integrated municipal urbanism rather than isolated projects, while flagship interventions such as Bab Antakiya, the Green Path, the river corridor, and the Citadel surroundings materialized this logic. The study also finds that this vision remained institutionally vulnerable because of political centralization and limited municipal autonomy. It concludes that post-war recovery should build on critical continuity rather than reconstruction from scratch. Full article

Most Sustainable Development Goals (SDGs) involve water, but integrated water resources management (IWRM) does not address them explicitly, especially the important health and sanitation goals. IWRM has structural problems and has been used mainly as a development tool rather than a way to manage water. There is no consensus among the professional communities about the methods and value of IWRM, and its inherent problems make assessment of its success difficult. It surveys national levels while most applications are at local levels. Efforts to improve and assess progress in the water, sanitation, and hygiene (WASH) sector faced similar obstacles, and a new approach based on household surveys was adopted. The mismatch between IWRM and WASH is caused by the polarization between communities of practice for public health and water management. Tools posted by the Global Water Partnership (GWP) do not address WASH explicitly, and the public health profession does not embrace IWRM. These problems can be mitigated by a new definition of IWRM that combines WASH with other water-related issues. To address its complexity, situational archetypes can be mapped to local levels and explained by case studies. To assess progress in IWRM implementation, a new approach should focus on results at local levels rather than methods at the national levels and address the polarization with WASH. SDG reporting relating to water should focus on local outcomes with WASH included, as well as key purposes that include water for food, flood control, drought resilience, and the sustainability of ecosystems. Progress could be assessed via outcome data collected by sector organizations. The GWP program could adopt a new definition of IWRM and new methods of assessment. Full article

Under the open-innovation paradigm, firms’ management of innovation output has surpassed traditional approaches such as confidentiality and patenting, evolving toward mechanisms such as strategic knowledge disclosure (SKD). As firms become increasingly embedded in global open-innovation networks, reconciling the tension between the need for innovation-knowledge disclosure and the reality of external-relationship embedding has emerged as a research agenda. Grounded in open-innovation theory, this study uses a panel of A-share manufacturing companies spanning 2009–2021 to examine how customer dependence (CD) affects suppliers’ SKD. Employing fixed-effects negative binomial panel regression, as well as robustness checks, we find that stronger CD significantly weakens suppliers’ SKD. Mechanism analysis shows that this effect operates through the channel of research and development (R&D) investment. Suppliers with high CD are more likely to reduce R&D investment, thereby suppressing their SKD. We further find that knowledge accumulation positively moderates the relationship between CD and suppliers’ SKD, while market competitiveness negatively moderates it. By constructing a theoretical framework for suppliers’ SKD under CD, this study enriches our understanding of the mechanisms and boundary conditions of firms’ SKD in terms of supply-chain relationships. The findings offer actionable insights to help suppliers embedded in supply-chain business partnerships formulate SKD. Full article

Construction firms in emerging markets operate in highly volatile environments that threaten business continuity and sector-wide resilience. This study provides a novel, integrated framework that links multiple strategic survival models to construction business resilience and development in Ghana’s construction industry, with particular emphasis on the evolving role of digitalisation. Four survival models are conceptualised as strategic portfolios: Innovation and Digital Transformation, Diversification and Growth, Lean and Resilience, and Strategic Risk and Partnerships. A quantitative research design was employed, using structured questionnaires administered to 128 construction industry stakeholders. Data were analysed using Partial Least Squares Structural Equation Modelling to assess direct, indirect, and mediating effects among survival models, construction business resilience, and construction business development. All four survival models have significant positive effects on construction business resilience, with Diversification and Growth (β = 0.404) and Innovation and Digital Transformation (β = 0.377) exerting the strongest influence, followed by Strategic Risk and Partnerships (β = 0.265) and Lean and Resilience (β = 0.207). The structural model explains 55.7% of the variance in construction business resilience, while construction business resilience is positively and strongly related to construction business development (β = 0.439), accounting for 19.3% of its variance. The findings show, for the first time in this context, that construction business resilience systematically mediates the relationship between distinct strategic survival portfolios and business growth in an emerging-market construction sector. This study advances the resilience and construction management literature by empirically demonstrating the hierarchical effectiveness of different survival models and by positioning construction business resilience as both a defensive capability and a strategic engine of sustainable development for construction firms in volatile markets. This paper recommends that firms develop composite resilience portfolios that integrate these strategies, while policymakers foster enabling regulations, digitalisation incentives, and joint risk-sharing arrangements that amplify sector-wide resilience. It offers a portfolio-based perspective on how to combine diversification, digital transformation, lean management, and strategic partnerships to build resilient, growth-oriented construction businesses. Convenience sampling and a cross-sectional design in a single national context highlight the need for longitudinal and cross-country research to validate and extend the proposed framework.

Background: The importance of evidence-based practice (EBP) is well recognized, yet its implementation remains challenging across healthcare systems, especially in low- and middle-income countries, where resource constraints, workforce turnover, and organizational barriers can hinder practice change. The traditional approach to implementation has focused on training, guidelines, and leadership support; however, these strategies do not always sustain frontline staff engagement. Objective: This descriptive case study examined how social movement strategies supported a multi-year EBP implementation initiative within a Philippine academic–clinical partnership. Methods: Program documents, training records, implementation reports, curriculum materials, and internal records of guideline-related activities were reviewed. Data were organized using the Social Movement Action Framework, with attention to preconditions for change, social movement mechanisms, and implementation outcomes. Results: The initiative included champion training, guideline integration, awareness activities, academic–clinical collaboration, and practice-focused implementation efforts related to breastfeeding, vascular access device management, and pressure injury prevention. These activities provided observable process indicators of stakeholder engagement, shared ownership, and continued use of guideline-informed practices. Conclusions: Social movement strategies may offer a useful complementary lens for understanding how EBP implementation gains momentum in real-world healthcare settings. Additional studies should explore their relationship to implementation outcomes and clinical care processes. Full article

This study applies the Actor-Centered Power (ACP) framework to analyze urban green-space governance in three Asian cities, focusing on how power is distributed and exercised among actors in the management of their representative multipurpose parks: Seoul Forest in Seoul, Da’an Forest Park in Taipei, and Yoyogi Park in Tokyo. Conventionally used in large-scale forest governance in the Global South, ACP is extended here to East Asian cities of the Global North. This can provide nascent insight into how coercion, (dis)incentives, and information operate across different institutions. The study found that the initial formation of the parks was driven by potent actors through coercive measures in all three cities. While Seoul maintains centralized statutory governance under the national act, Taipei adopts a decentralized governance model that foregrounds subordinate actors, notably exemplified by the higher education-oriented foundation. This organization promotes citizen science involvement and community-based stewardship. Tokyo, by contrast, uses a public–private partnership model that supports private sector commercial collaboration. This comparative case study demonstrates that the ACP framework is well-suited for analyzing urban green-space governance, as it distinguishes between power subjects (potentates and subordinates) and power sources (coercion, incentives, and information), providing theoretical and managerial implications. Through the lens of the ACP framework, this study argues that distinct institutional arrangements produce divergent power configurations for urban green-space management even within similarly developed urban contexts.
