Due to the increasingly severe energy crisis and extreme climate conditions in recent years, the development and use of alternative clean energy sources have become increasingly important. This study evaluates the energy performance of applying residential solid oxide fuel cells (SOFCs) in a typical passive-designed residential village house in Xi’an. Furthermore, the study integrates photovoltaic (PV) systems and storage batteries with a solid oxide fuel cell co-generation system (SOFC-CGS) to enhance its overall energy performance. The results show that when the SOFC-CGS operates independently, it can provide stable electricity. However, due to its limited capacity, it only meets 43% of the total energy demand and cannot fully satisfy the heating requirements. In this energy supply scenario, the SOFC-CGS heating efficiency reaches 25%, the power generation efficiency reaches 42%, and the overall efficiency reaches 67%. After integrating the PV battery system with the SOFC-CGS, the addition of photovoltaic and battery systems boosts the energy self-sufficiency rate by 32 percent, reaching 75%. In other words, this clean energy combination can cover 75% of the household’s traditional energy consumption. In addition, the heating efficiency increases by 2 percentage points to 27%, the power generation efficiency rises by 4 percent to 46%, and the overall system efficiency improves by 6 percent to reach 73%. Furthermore, the utilization rate of the photovoltaic battery system also rises from 25% to 73%: an increase of 48 percent. Therefore, according to the analysis results, integrating PV and storage batteries with the SOFC-CGS proves to be a profitable and efficient solution for application in passive-designed village houses in Xi’an.

Employee retention remains a critical challenge in human resource management (HRM). Embeddedness theory offers a vital framework to understand retention dynamics, yet its development within HRM lacks systematic mapping. This study systematically examines the intellectual evolution, thematic clusters, and emerging trends of embeddedness theory in HRM from 1995 to 2025, addressing three research questions: (1) How has the theory developed over time? (2) What are the key research themes and conceptual structures? (3) Which emerging trends can inform future HRM practice? A bibliometric and science mapping analysis was conducted on 562 peer-reviewed articles from Web of Science using co-citation, co-word clustering, and keyword evolution techniques. Three distinct phases were identified: formative (1995–2005), expansion (2006–2015), and maturation (2016–2025). Findings reveal a dual focus on micro-level constructs, including job satisfaction and turnover intention, and macro-level themes, such as organizational commitment and performance. Recent trends highlight organizational and institutional contexts, cross-cultural perspectives, and post-pandemic dynamics. The study provides the first comprehensive longitudinal mapping of embeddedness theory in HRM, clarifying its intellectual structure, key contributors, and evolving research frontiers. These insights offer actionable guidance for scholars and practitioners, emphasizing the integration of multi-level and contextual factors to enhance employee retention in increasingly complex and globalized work environments.

The global transition to renewable energy sources is essential to carbon neutrality and ensuring energy security. First, the paper presents a comprehensive literature review of the main technological breakthroughs in bioenergy, hydro energy, solar energy, onshore and offshore wind energy, ocean energy, and geothermal energy, selecting the latest papers published. Next, key scientific challenges, environmental and economic constraints, and future research priorities for each of the six renewable energies were outlined. Then, to emphasize the important contribution of renewable energies to total energy production and the proportions of each type of renewable energy, the evolution of global electricity generation from all six renewable sources between 2000 and 2023 was analyzed. Thus, in 2023, the global electricity generation weight of each renewable energy in total renewable energy ranks hydro energy (47.83%) first, followed by onshore and offshore wind energy (25.8%), solar energy (18.19%), bioenergy (7.07%), geothermal energy (1.1%), and ocean energy (0.01%). After that, the bibliometric analysis, conducted between 1 January 2021 and 1 October 2025 on the Web of Science (WoS) database and using the PRISMA approach and VOSviewer version 1.6.20 software, enabled the identification of the most cited papers, publications and citation number by WoS categories, topics, correlation with Sustainable Development Goals, authors’ affiliation, publication title, and publisher. Furthermore, the paper presents a network visualization of the link between co-occurrences and all keywords, imposing minimum thresholds of 10, 20, and 30 occurrences per keyword, and computes the network density based on the number of edges and nodes. Finally, additional analysis included the most used keywords in different co-occurrences, a word cloud of occurrences by total link strength, regression of occurrences versus total link strength, and correlations between citations and documents and between citations and authors. Carbon neutrality and a resilient energy future can only be achieved by integrating renewable sources into hybrid systems and optimized smart grids. Each technological progress stage will bring new challenges that must be addressed cost-effectively. Full article

This paper presents a bibliometric and literature review on decarbonization strategies in sustainability-oriented contractor selection within Integrated Project Delivery (IPD) frameworks. The study analyzes 972 journal articles published between 2002 and 2024 from Scopus, complemented by Google Scholar for thematic insights. Bibliometric techniques in R were applied to identify influential publications, research trends, and thematic clusters. The review highlights documented benefits of integrating decarbonization into contractor evaluation, including lifecycle carbon reduction, ESG alignment, and early-stage material optimization. Challenges remain in terms of limited lifecycle data, absence of standard benchmarks, and organizational resistance. Critical success factors identified include policy alignment, availability of assessment data, and collaborative stakeholder engagement. The findings demonstrate that incorporating carbon-related performance indicators into early procurement decisions can reshape prequalification standards and strengthen sustainable project delivery. Citation and co-word analysis reveal emerging research trends, including digital innovations such as artificial intelligence for contractor evaluation and emissions tracking. This study provides both a research foundation and a strategic guide for construction professionals, policymakers, and sustainability advocates aiming to align IPD with global decarbonization targets.

This study examines how an inland city constructs a cutting-edge technological identity through media framing, thereby addressing a critical gap in urban image research. Focusing on Guiyang’s reinvention as “China Data Valley”, we analyzed a comprehensive corpus of news articles (January 2018–September 2025) using an integrated computational framework that incorporates descriptive statistics, LDA topic modeling, and co-word network analysis. This study investigated three dimensions: the distribution of discourse power among media actors, the narrative architecture of the urban image, and the distinct framing strategies employed by different media types. The results reveal that national official media are the primary drivers of image construction. The narrative is structured around a three-layer architecture. Furthermore, media types exhibit distinct framing strategies. This study provides practical insights for urban branding and contributes to media framing theory by extending its geographical focus to inland technology hubs and elucidating image construction within China’s unique media ecosystem. Finally, it proposes a replicable analytical model for latecomer regions seeking a discursive breakthrough in the digital era. Full article

Community-level overdose prevention interventions often require collaboration among organizations from various sectors including emergency medicine, criminal justice, harm reduction, and drug treatment organizations, yet little is known about ways to foster interorganizational collaboration among organizations with very different missions and in different socio-political contexts. This paper presents results from interviews with key informants involved in overdose prevention coalitions in two counties in Wisconsin (n = 45). Key informants were purposively selected from 31 different organizations in sectors including harm reduction, drug treatment, emergency medicine, and law enforcement. Interviews asked participants to describe the overdose crisis in their communities and the work they do, including any partnerships or coalitions formed with other organizations. We conducted thematic analysis using inductive and deductive coding. Participants’ experiences illuminate strategies and actions that facilitated coalitions’ work (interorganizational processes) and changed the context in which they worked to be more accepting of harm reduction efforts and less stigmatizing and punitive toward people who use opioids (PWUO). These included getting the word out in community-facing events to educate the public and destigmatize harm reduction, working with representatives across the CoC in various sectors, and actively working with them to create shared missions. Key people acted as bridges while others had the power to convene multiple agencies to a common cause. Overdose Fatality Reviews (OFRs) were found to be particularly helpful in identifying gaps in the current Opioid CoC and developing programs in collaboration with other organizations to address them. Organizational empowerment offers a useful framework for understanding how to facilitate IOC at the intra- (e.g., community education to reduce stigma, inter- (bridging roles by key actors), and extra-organizational levels (e.g., policy changes supporting naloxone access). These strategies can be used by coalition members and tested in future community-level overdose responses. Full article

In the face of marketization and globalization of agricultural product trade, ensuring food security through effective seed industry policies has become a vital objective for many nations, especially for developing countries striving toward this goal. The evolution of seed industry policies to meet the challenges of marketization and globalization has not been extensively examined. This study seeks to answer how China’s seed industry policies have been continuously adjusted since the 21st century to ensure seed security and food security amidst marketization and globalization. Focusing on 96 national-level seed policies issued between 2000 and 2024, we employ methods such as co-word analysis, social network analysis (SNA), cluster analysis, and content analysis to explore policy evolution from five perspectives: policy stakeholders, policy issues, objectives, discourse, and tools. The key findings are: (1) China’s seed policies have largely aligned with the country’s marketization and globalization processes, progressing through three stages: seed industry marketization, response to globalization, and modernization and self-strengthening, forming a comprehensive policy framework. (2) The scale of cooperation networks among policy issuers has expanded, shifting toward a loose-centralized structure, with the Ministry of Agriculture and Rural Affairs as the core and coordinated involvement of other departments such as the Ministry of Industry and Information Technology and the State Administration for Market Regulation. (3) The policy discourse shifted from fostering a market-oriented environment to emphasizing seed industry innovation, reinforcing basic R&D capabilities, addressing innovation challenges, and promoting industrialization. (4) The policy paradigm transitioned from an initial phase of adjusting to market-oriented transformation to a comprehensive phase of modernization and self-reliance, with policy focus moving from incomplete market mechanisms and regulatory shortcomings toward issues like seed source bottlenecks, and objectives from reforming seed management to achieving technological independence. (5) The logic of policy evolution shows notable differences in attention focus related to management concepts, support for technological innovation, and promotion of quality seed breeding—shifting from regulation to service emphasis, from focusing on key projects to diversified innovation, and from importing superior varieties to breakthroughs in new breeds and technologies. These findings offer valuable insights for developing countries facing food security challenges. Full article

Bantu languages represent a typical example of how morphology and syntax are deeply intertwined. Indeed, these agglutinative languages employ affixes, hence morphemes, to express relations that in other languages—like Italian or English—are conveyed by independent words, in syntax. In particular, in this work, I am going to discuss Bantu causative and applicative constructions, which are formed by means of verbal extensions, i.e., affixes that adjoin to verb stems in order to derive complex syntactic structures. Through the comparison with other languages, in particular Italian and English, we will argue that a biclausal analysis of Bantu causatives is tenable and, even more, this analysis can be extended to applicative and ditransitive verbs, taking into consideration the different behaviour of symmetrical and asymmetrical Bantu languages. Finally, we will discuss the peculiar situation of Italian, which behaves like symmetrical Bantu languages as concerns object pronominalization in the complex constructions under analysis; we will conclude that the co-occurrence of clitic pronouns is linked to their different morphological forms, which suggests that they occupy different positions in the clitic/affix string, underlying once more how morphology and syntax feed each other.

Generation Z is becoming a dominant market segment and an essential source of talent in the hospitality industry. Their digital fluency, sustainability expectations, and preference for meaningful and personalized experiences are increasingly reshaping service delivery, marketing strategies, and workforce management in the hotel industry. Following the PRISMA 2020 guideline, this review systematically analyzed 131 peer-reviewed studies published between 2011 and 2025. Performance analysis, science mapping through co-word and Leiden clustering, and trend analysis were conducted using VOSviewer (v1.6.20) and Biblioshiny in RStudio (v2025.09.2). The findings reveal a rapidly expanding but relatively young field, with key themes clustered around technology acceptance (AI, service robots), experiential and sustainable consumption, digital engagement (word-of-mouth, social media), workforce dynamics (person–environment fit, leadership, quiet quitting), and emerging topics such as experiential education, ethics, and self-efficacy. The study highlights the centrality of the Theory of Planned Behavior and technology acceptance models in explaining Gen Z’s decision-making, while also identifying substantial gaps in cross-cultural, ethical, and experiential research. Practical implications call hoteliers to integrate seamless digital services, robust sustainability initiatives, and adaptive talent management system to meet Gen Z’s evolving expectations.

Background and Objectives: Facebook groups have become support spaces for people with rare diseases such as amelogenesis imperfecta (AI). While their potential for revealing patient needs is recognized, no systematic analysis has been conducted in France. This study aims to better understand the psychological and practical needs of French AI patients by analyzing interactions within a dedicated Facebook group. Methods: A semantic and thematic analysis was conducted on 881 texts (39,647 words) from the French Facebook group Amelogenesis Imperfecta. A custom tool, TEXTRA©, and IRaMuTeQ© software were used for analysis, including similarity analysis (lexical co-occurrences), Descending Hierarchical Classification (DHC), Correspondence analysis to reveal discourse structures. Results: Correspondence analysis revealed two main discourse trends: individual experiences (symptoms, treatment logistics, and medical engagement) and collective narratives (focused on awareness, mobilization, and institutional recognition). DHC identified four thematic classes: (a) difficulties accessing healthcare, (b) genetic framing and family implications, (c) dental symptoms and treatment experiences, and (d) community advocacy. These findings highlight how the group fosters emotional support, peer exchange, and empowerment. Conclusions: Online communities play a vital role in supporting patients with rare diseases. This study shows that the analysis of user-generated content can guide improvements in clinical practice, psychosocial support, and health policy. Full article

The rise of digital platforms has transformed heritage interpretation from a single official narrative to multi-stakeholder participation. This study investigates how such platforms mediate the formation of a sense of place at the Kulangsu World Heritage Site (WHS). Data were collected from official narrative texts and user-generated content (UGC) on Dianping and Ctrip, and analyzed using high-frequency word statistics and semantic network analysis. The results reveal a clear divergence between official narratives, which emphasize Outstanding Universal Value (OUV), and tourist perceptions, which focus on visual landmarks and “check-in” practices shaped by the “digital gaze.” Moreover, the sense of place is shown to be a dynamic process, co-constructed through pre-visit expectations, on-site experiences, and post-visit reflections. The findings also highlight a transformation in tourists’ roles, shifting from passive cultural consumers to active participants in the co-construction of heritage values, with digital platforms serving as critical mediators. Theoretically, the study advances digital heritage scholarship by clarifying the mechanism of the digital gaze and the dynamic nature of sense of place. Practically, it underscores the importance of integrating official narratives with UGC to strengthen OUV communication, foster broader public engagement, and support the sustainable development of WHSs.

This paper explores how digital crowdsourcing platforms communicate sustainability-oriented innovation and mobilise stakeholder engagement. Through a directed content analysis of three platforms (OpenIDEO, San Francisco, CA, USA; Enel Innovation Hub, Rome, Italy; and InnoCentive, Waltham, MA, USA). The study examines communication strategies, participation models, and alignment with the United Nations Sustainable Development Goals (SDGs). Results show that communication is not neutral but functions as a governance mechanism shaping who participates, how innovation is framed, and what outcomes emerge. OpenIDEO fosters inclusive co-creation and SDG alignment, Enel Innovation Hub highlights technical readiness and energy transition, and InnoCentive relies on rewards and competition. Word-frequency analysis confirms these emphases, while interpretation through Motivation Crowding Theory, Social Exchange Theory, and Transaction Cost Theory explains how motivational framing, legitimacy signals, and participation structures affect engagement. The study contributes to research on open innovation and platform studies by demonstrating the constitutive role of communication in enabling or constraining sustainable collective action. Practical implications are outlined for platform designers, marketers, and policymakers seeking to align digital infrastructures with systemic sustainability goals. Full article

Toponym groups are fundamental units of quantitative spatial analysis of toponyms. Using suitable technical methods to investigate the spatial distribution and co-occurrence characteristics of these groups has significant implications for identifying cultural regions within geographical spaces and elucidating spatial differentiation and integration of regional cultural characteristics underlying toponyms. Existing research has mainly relied on traditional spatial distribution models such as standard deviation ellipse (SDE) and kernel density estimation (KDE) to analyse the characters used in toponyms. In addition, few quantitative studies exist on the co-occurrence of multiple types of toponym groups from the perspective of words used in toponyms. This study introduced methods, including the local co-location quotient, to propose a general framework for toponymic co-occurrence research and a new toponymic co-occurrence index (TCOI). Data from 64,981 village toponyms in Liaoning Province, China, were used to analyse spatial co-occurrence characteristics of five high-frequency two-character village toponym groups. In addition, two high-frequency single-character toponym groups and three low-frequency two-character toponym groups were used for verification, with a simultaneous comparison of the SDE and KDE methods. The findings indicated that: (1) the proposed general framework and TCOI effectively support toponymic spatial measurement and have good applicability and expansibility; (2) the TCOI enables a more accurate scientific assessment of co-occurrence characteristics of toponymic groups at different scales, thereby enhancing the technical level of toponymic spatial measurement; (3) the TCOI for Liaoning Province was 28.63%, indicating that toponym groups exhibited a partially integrated yet relatively exclusive spatial distribution pattern. The spatial differentiation patterns of rural toponym cultural landscapes in Liaoning Province provide a scientific basis for promoting cultural geography research and strengthening toponym protection.

The growing use of bibliometric methods in literature reviews has intensified concerns about methodological transparency and consistency. This study compares English-language reviews authored by China-affiliated and non-China-affiliated researchers between 2015 and 2024. Through bibliometric content analysis and co-word network mapping, it evaluates the following: (1) the use and purposes of bibliometric software; (2) the clarity of methodological reporting, including software versions, threshold settings, data preprocessing, and database selection; (3) the extent to which limitations are acknowledged and recommendations proposed; and (4) the dominant conceptual themes shaping research practices. The analysis covers 50 highly cited reviews (25 per group) and 4000 additional papers for thematic mapping. Findings show both convergence and divergence: while tools such as VOSviewer, CiteSpace, Gephi, and Bibliometrix are widely adopted, non-China-affiliated studies exhibit greater transparency and reflexivity, whereas China-affiliated research often emphasizes output metrics and underreports methodological challenges. These contrasts reflect broader epistemological norms and research cultures. This study underscores the need for unified reporting standards and contributes to meta-research by offering practical guidance to improve the transparency, comparability, and rigor of bibliometric-supported literature reviews.

Key concepts such as “carbon footprint”, “carbon neutral”, “carbon neutrality”, “low carbon”, and “net-zero emissions” have gained prominence in the context of climate change, a current issue that has become an urgent global challenge caused by anthropogenic activities, including agriculture. This bibliometric review analyzed the use of these concepts in mitigation strategies for the coffee sector, since coffee production significantly contributes to greenhouse gas (GHG) emissions, primarily due to land use change, fertilizer use, and processing methods, and therefore, sustainable approaches within the whole coffee value chain need to be implemented. A total of 105 documents from the Scopus database, covering publications from January 1988 to June 2023, were analyzed. Co-word analysis and co-occurrence mapping techniques, together with traditional bibliometric laws and historical evolution analysis using VOSviewer and Bibliometrix, were applied. The evolution of research over time revealed that the first concept introduced for documenting the reduction in greenhouse gas (GHG) emissions was “low carbon emissions” in 1909, but it was not until 2008 that the first document was published establishing a link between “low carbon emissions” and “coffee”. In 2015, two more concepts, “carbon neutral” and “carbon neutrality”, documented since 1968 and 1995, respectively, were used in articles related to coffee. So far, the most relevant concept in quantifying GHG emissions in the context of coffee production activities has been “carbon footprint”. When it comes to new documents linking key concepts to coffee, between 2015 and 2018, there was an average of six documents per year. Since 2019, the average has remained at 15, highlighting the need to continue documenting climate change mitigation strategies in the coffee sector. Practical application of our findings for coffee sustainability programs must include the adoption of on-farm sustainable agricultural practices that span the entire value chain. In conclusion, this study underscores the importance of concepts such as “carbon footprint” and “carbon neutrality” as key pillars in the development of effective climate change mitigation strategies in the coffee sector and the significance of their integration into future research and global policies with practical applications, with far-reaching implications for sustainable agriculture in the near future.
