The increasing frequency and intensity of extreme weather events pose significant challenges to mountain communities, particularly in terms of flash flood risks. This study presents a framework for stress testing and evaluating flood resilience in mountain communities through the integration of high-resolution InfoWorks ICM two-dimensional hydrodynamic modeling and systematic resilience assessment. The framework makes three key innovations: (1) multi-scale temporal stress scenarios combining short-duration extreme events (1–2 h) with long-duration persistent events (24 h) and historical extremes; (2) integrated infrastructure–drainage stress analysis that explicitly models roads’ dual role as critical infrastructure and emergency drainage channels; and (3) dynamic resilience quantification under multiple stressors across 15 systematically designed stress conditions. Using Western Beijing as a case study, the model is validated, achieving Nash–Sutcliffe efficiency values exceeding 0.9, demonstrating its robust capability in simulating complex mountainous terrain flood processes. Through systematic analysis of fifteen rainfall scenarios designed based on Chicago rainfall patterns and historical events (including the July 2023 Haihe River basin flood), encompassing various intensities (30–200 mm/h), durations (1 h, 2 h, 24 h), and return periods (10, 50, 100 years), the key findings include the following: (1) A rainfall intensity of 60 mm/h represents a crucial threshold for system performance, beyond which significant impacts on community infrastructure emerge, with built-up areas experiencing inundation depths of 0.27–0.4 m that exceed safe passage limits. (2) Road networks become primary drainage channels during intense precipitation, with velocities exceeding 5 m/s in village roads and exceeding 5 m/s in country road sections, creating significant hazard potential. (3) Four major risk spots were identified with distinct waterlogging patterns, characterized by maximum depths ranging from 0.8 to 2.0 m and recovery periods varying from 2 to 12 hours depending on the topographic confluence effects and drainage efficiency. (4) The system demonstrates strong recovery capability, achieving >90% recovery within 3–6 hours for short-duration events, while showing vulnerability to extreme scenarios, with performance declining to 0.75–0.80, highlighting the coupling effects between water depth and flow velocity in steep terrain. This research provides quantitative insights for flood risk management and for enhancing community resilience in mountainous regions, offering valuable guidance for infrastructure improvement, emergency response optimization, and sustainable community development. This study primarily focuses on physical resilience aspects, with socioeconomic and institutional dimensions representing important directions for future research. Full article

Residents’ values in social housing retrofit extend beyond energy efficiency targets to encompass complex social and physical considerations, shaping their acceptance and experience of interventions. These values appear to influence retrofit success yet are often overlooked in policy and practice that prioritise technical performance. This paper investigates what residents value in social housing retrofit through a focus group method with the Sutton Estate in London, combining institutional stakeholder (housing association and architect) and resident perspectives. Content analysis of focus group questionnaires, discussions, and consensus-building activities revealed four key resident values: (1) good stakeholder relationships, emphasising trust-building through personal connections; (2) access to information, requiring clear, continuous communication through multiple channels; (3) comfort, health, and safety, integrating physical and mental wellbeing; and (4) building and community longevity, focusing on preserving building character and social sustainability. The findings suggest that social housing retrofit may benefit from a holistic approach integrating residents’ values throughout the project lifecycle, addressing the social, physical, and long-term sustainability of homes and communities. The findings highlight the importance for housing associations, architects, and policymakers to consider residents’ values when developing retrofit strategies, balancing technical requirements with residents’ needs and priorities.

Floods pose a growing threat globally, causing tragic loss of life, billions in economic damage annually, and disproportionately affecting socio-economically vulnerable populations. This paper aims to improve flood-risk communication for community leaders by exploring the application of artificial intelligence. We categorize U.S. flood information sources, review communication modalities and channels, synthesize the literature on community leaders’ roles in risk communication, and analyze existing technological tools. Our analysis reveals three key challenges: the fragmentation of flood information, information overload that impedes decision-making, and the absence of a unified communication platform to address these issues. We find that AI techniques can organize data and significantly enhance communication effectiveness, particularly when delivered through infographics and social media channels. Based on these findings, we propose FLAI (Flood Language AI), an AI-driven flood communication platform that unifies fragmented flood data sources. FLAI employs knowledge graphs to structure fragmented data sources and utilizes a retrieval-augmented generation (RAG) framework to enable large language models (LLMs) to produce contextualized narratives, including infographics, maps, and cost–benefit analyses. Beyond flood management, FLAI’s framework demonstrates how AI can transform public service data management and institutional AI readiness. By centralizing and organizing information, FLAI can significantly reduce the cognitive burden on community leaders, helping them communicate timely, actionable insights to save lives and build flood resilience.

This study examines how students perceive factors contributing to their sense of belonging (SoB) in an online project-based master’s course in social innovation, incorporating collaboration with external stakeholders and structured around real-world challenges from external partners. SoB has been shown to impact academic outcomes positively, but online teamwork and collaboration outside the institution walls present unique challenges. The study adopts a qualitative approach and an interpretivist standpoint to find meaningful aspects and generate an understanding of positions among the students. Data was gathered through interviews, allowing students to express their unique experiences and perspectives on SoB in the context of a master’s course, with participants from several countries. Thematic analysis of the interview data identified the following seven categories related to students’ perceived belonging: team formation and trust, personal introductions, group continuity, access to teachers, use of informal communication channels, shared tools, and digital fluency. Furthermore, working towards a common challenge or goal seems to promote SoB among team members. The results indicate that SoB was shaped by multiple interrelated factors, with team-based collaboration and structured group dynamics playing a central role. The study contributes to ongoing research on student belonging by identifying specific practices that may support SoB in digitally supported, team-oriented learning environments. Full article

Examining public attitudes towards COVID-19 vaccination is crucial for understanding the global effort to combat the ongoing pandemic. Social media platforms such as YouTube play a significant role in the dissemination of information and misinformation about the vaccine, making it imperative to analyze user comments to gain insights into vaccine perceptions. Analyzing the Philippines case is particularly significant as it provides insights into the attitudes towards COVID-19 vaccination in a country that has been heavily impacted by the pandemic. The current study investigates the discourse surrounding vaccine hesitancy in comments on YouTube videos announcing the COVID-19 vaccination campaign by the Philippines national TV channels and its impact on engagement levels. A total of 741 YouTube comments were analyzed, with 80% exhibiting vaccine-hesitant related discourse. The results indicate that those with negative attitudes towards COVID-19 vaccination exhibit higher engagement levels than those supporting vaccination (p < 0.05). Additionally, the most commonly used themes in vaccine-hesitant posts were “ingredients”, “health department control”, “pharmaceutical interest”, and “adverse effects”. Moreover, 134 sources were identified among the posts, with vaccine-hesitant posts utilizing more sources than supportive vaccine posts (p < 0.001). The most significant information sources utilized in the posts were related to other YouTube users, politicians, clinicians, and scientific papers. Finally, a total of 890 discourses were coded, with the most frequently used discourse types among vaccine-hesitant posts being negationist, institutional, preventive, political, and pharmaceutical. These findings offer valuable insights into the nature and prevalence of vaccine hesitancy discourse on social media platforms and its impact on public engagement. This study highlights the importance of targeted communication strategies and the provision of accurate information from reliable sources in addressing vaccine hesitancy. Full article

The emergence of large-scale quantum computing presents an imminent threat to contemporary public-key cryptosystems, with quantum algorithms such as Shor’s algorithm capable of efficiently breaking RSA and elliptic curve cryptography (ECC). This vulnerability has catalyzed accelerated standardization efforts for post-quantum cryptography (PQC) by the U.S. National Institute of Standards and Technology (NIST) and global security stakeholders. While theoretical security analysis of these quantum-resistant algorithms has advanced considerably, comprehensive real-world performance benchmarks spanning diverse computing environments—from high-performance cloud infrastructure to severely resource-constrained IoT devices—remain insufficient for informed deployment planning. This paper presents the most extensive cross-platform empirical evaluation to date of NIST-selected PQC algorithms, including CRYSTALS-Kyber and NTRU for key encapsulation mechanisms (KEMs), alongside BIKE as a code-based alternative, and CRYSTALS-Dilithium and Falcon for digital signatures. Our systematic benchmarking framework measures computational latency, memory utilization, key sizes, and protocol overhead across multiple security levels (NIST Levels 1, 3, and 5) in three distinct hardware environments and various network conditions. Results demonstrate that contemporary server architectures can implement these algorithms with negligible performance impact (<5% additional latency), making immediate adoption feasible for cloud services. In contrast, resource-constrained devices experience more significant overhead, with computational demands varying by up to 12× between algorithms at equivalent security levels, highlighting the importance of algorithm selection for edge deployments. Beyond standalone algorithm performance, we analyze integration challenges within existing security protocols, revealing that naive implementation of PQC in TLS 1.3 can increase handshake size by up to 7× compared to classical approaches. To address this, we propose and evaluate three optimization strategies that reduce bandwidth requirements by 40–60% without compromising security guarantees. Our investigation further encompasses memory-constrained implementation techniques, side-channel resistance measures, and hybrid classical-quantum approaches for transitional deployments. Based on these comprehensive findings, we present a risk-based migration framework and algorithm selection guidelines tailored to specific use cases, including financial transactions, secure firmware updates, vehicle-to-infrastructure communications, and IoT fleet management. This practical roadmap enables organizations to strategically prioritize systems for quantum-resistant upgrades based on data sensitivity, resource constraints, and technical feasibility. Our results conclusively demonstrate that PQC is deployment-ready for most applications, provided that implementations are carefully optimized for the specific performance characteristics and security requirements of target environments. We also identify several remaining research challenges for the community, including further optimization for ultra-constrained devices, standardization of hybrid schemes, and hardware acceleration opportunities.

Due to the promotion of sustainable development goals and rapid economic development, the problem of rural sewage treatment is becoming increasingly severe. In order to understand the research hotspots, progress, and trends of ecological treatment technology for rural sewage at home and abroad, this article analyzes relevant literature published between 2000 and 2023 based on the core collection databases of China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) using VOSviewer and CiteSpace visualization software. The research results indicate a continuous increase in attention to ecological treatment technologies for rural sewage, both domestically and internationally. Although China started relatively late in this field, it has developed rapidly. “China Water & Wastewater” has had a significant impact in related fields domestically, and a top-tier journal has not yet been founded by China internationally. The collaboration between research authors and institutions is evident, with CNKI focusing on exploring specific governance technologies, while WOS pays more attention to the overall governance framework and critical technologies. The research hotspots of ecological treatment technology for future village and town sewage include specific treatment technologies, treatment efficiency, overall treatment strategies, and environmental impact assessments. At the same time, cross-regional and cross-border cooperation should be strengthened, interdisciplinary collaboration should be promoted, open cooperation platforms should be established, diversified publishing channels should be supported, and research on microbial communities and non-point source pollution should be deepened.

This study examines adaptation strategies to mitigate the risks posed by Glacial Lake Outburst Floods (GLOFs) in the Hindu Kush Himalayan (HKH) region, encompassing Pakistan, India, Nepal, Bhutan, and Afghanistan. GLOFs occur when water is suddenly released from glacial lakes and they present significant threats to communities, infrastructure, and ecosystems in high-altitude regions, particularly as climate change intensifies their frequencies and severity. While there are many studies on the changes in glacial lakes, studies on adaptation to GLOF risks are scant. Also, these studies tend to focus on case-specific scenarios, leaving a gap in comprehensive, region-wide analyses. This review article aims to fill that gap by synthesizing the adaptation strategies adopted across the HKH region. We conducted a literature review following several inclusion and exclusion criteria and reviewed 23 scholarly sources on GLOF adaptation. We qualitatively synthesized the data and categorized the adaptation strategies into two main types: structural and non-structural. Structural measures include engineering solutions such as lake-level control, channel modifications, and flood defense infrastructure, designed to reduce the physical damage caused by GLOFs. Non-structural measures include community-based practices, economic diversification, awareness programs, and improvements in institutional governance, addressing social and economic vulnerabilities. We found that Afghanistan remains underrepresented in GLOF-related studies, with only one article that specifically focuses on GLOFs, while Nepal and Pakistan receive greater attention in research. The findings underscore the need for a holistic, context-specific approach that integrates both structural and non-structural measures to enhance resilience across the HKH region. Policy-makers should prioritize the development of sustainable mechanisms to support long-term adaptation efforts, foster cross-border collaborations for data sharing and coordinated risk management, and ensure that adaptation strategies are inclusive of vulnerable communities. Practitioners should focus on strengthening early warning systems, expanding community-based adaptation initiatives, and integrating traditional knowledge with modern scientific approaches to enhance local resilience. By adopting a collaborative and regionally coordinated approach, stakeholders can improve GLOF risk preparedness, mitigate socioeconomic impacts, and build long-term resilience in South Asia’s high-altitude regions.

In recent decades, the concept of innovation has gained prominence in the public sector as governments, facing economic constraints, seek solutions to increasingly complex problems. Innovation has emerged as a potential strategy to address these challenges, despite the significant obstacles it poses to traditional bureaucratic structures. Nevertheless, the notion of innovation has become widespread globally. This paper aims to explore the sources of innovation and the potential pathways for its effective consolidation. It advocates for a “human-centered” approach to ensure successful integration and demonstrates that innovation is the result of a multifaceted creative process. The consolidation of innovation, as argued, hinges on the credibility of its source—specifically, public administration. Consequently, political and administrative leadership must be persuaded to invest in innovative communication channels, both internal and external, to foster organizational flexibility and adaptability.

Gender equality is a fundamental principle that forms the basis of modern society. In the context of the Greek Public Administration, the promotion of gender equality is highlighted as a priority. However, despite efforts, incidents of violation of this principle continue to occur. In this context, the Integrity Advisor is emerging as an important tool for addressing incidents of gender equality violations, being the guardian of coherence and transparency in the public sector. The Integrity Advisor represents the ‘guardian’ of values and ethical principles within the public administration. His/her role focuses on ensuring that public organizations comply with the principles of transparency, accountability, and ethics. In this context, the violation of the principle of gender equality emerges as a specific area of intervention for the Integrity Advisor. The institutionalization of the Integrity Advisor is an innovative attempt to create an institution capable of helping any public body to ‘confide’ problems that have been identified in its environment and to mediate their management, the possible finding of a solution, or their referral to the appropriate authorities. The Integrity Advisor is required to develop a strong channel of communication with public sector employees and executives to establish a sense of security and trust among all. Full article

Floods are the natural hazards that cause the most damage and affect the most people in Spain. However, the response of the population and the actions they take before, during and after the emergency can be inappropriate due to inaccurate risk perception and preparation. This paper presents an analysis of the floods of 22–23 October 2019 in the upper area of the Francolí watershed (Catalonia, NE Spain), with the aim of analysing how to improve public perception and impact estimation through citizen science. To this end, a campaign (FLOODUP-Francolí) was organised together with a local institution that helped to engage participants. This consisted of a kick-off conference, a period of participation through tools adapted to the virtual format, including a questionnaire, and a face-to-face conference to present the results. The detailed analysis of the actions taken in the emergency allowed the identification of key aspects to improve flood prevention, response and recovery processes: clarity and consistency of communication, channels of communication, the timing of warnings, the preparedness of the population and the existence of agreed-upon self-protection protocols. Finally, this study demonstrates the contribution of citizen science initiatives in the field of natural hazards to improving community resilience and historical memory. Full article

The automatic identification system (AIS) is an essential tool for modern ships, enabling the broadcast of identification and location information. However, the current AIS standard lacks security features, meaning that messages exchanged via AISs are transmitted in plaintext, which leads to security issues such as privacy leakage. Most existing solutions rely on public key cryptography. This paper proposes a physical-layer key generation protocol based on the current AIS standard (ITU-R M.1371-5). In the case of unicast AIS communication, the protocol utilizes channel randomness to generate symmetric keys for securing communications. Compared to public key cryptography, the proposed protocol offers advantages such as low overhead, elimination of third parties, and ease of implementation. Finally, this paper discusses the security of the protocol against various threats as well as evaluates its performance and overhead. Under common speed and signal-to-noise ratio (SNR) conditions, The protocol generates Advanced Encryption Standard (AES) keys of different lengths in under 4000 ms, and these keys successfully pass the National Institute of Standards and Technology (NIST) randomness test.

Customer relationship management (CRM) has become a critical strategy for higher education institutions (HEIs) to enhance student engagement, institutional efficiency, and digital transformation. Despite its growing adoption, the evolution of CRM research in HEIs, including key contributors, dominant themes, and emerging trends, remains underexplored. This study conducts a bibliometric analysis of Scopus-indexed publications (2014–2024) to map the intellectual landscape of CRM research in higher education. Using Biblioshiny with Bibliometrix version 4.0 and VOSviewer version 1.6.20, this study analyzes publication trends, influential authors and institutions, keyword networks, and thematic developments. The findings indicate a transition from early research on service quality and academic reputation to advanced themes such as AI-driven CRM strategies, multi-channel communication, and social media analytics. While the United Kingdom, India, and Indonesia emerge as leading contributors, gaps persist in cross-cultural CRM applications, the integration of emerging technologies, and the development of standardized evaluation frameworks. This study contributes to CRM scholarship by mapping research trajectories, identifying underexplored areas, and offering actionable insights for future studies. It highlights the expanding role of CRM beyond student engagement, encompassing education quality, labor market, employment growth, technological progress and AI-driven decision-making. These findings emphasize the need for interdisciplinary approaches and robust academic performance to maximize CRM’s strategic potential in higher education. Full article

Within the framework of the research project “What are we forgetting in inclusive education? In participatory research in Galicia (PID2019-108775RB-C4)”, we developed a proposal that, based on the inclusion and community perspective, investigates the relationship between municipal corporations and educational centres for the design and implementation of the programmes that was municipally developed to promote educational inclusion. The role of municipalities as promoters of inclusion through educational programmes is analysed, focusing on the mediation of third-sector institutions. It also studies the demands of the agents that comprise a community perspective on inclusion. The qualitative–interpretative methodology is based on SWOT (strengths, weaknesses, opportunities and threats) and CAME (correct, adapt, maintain and explore) techniques to contrast the congruence of existing initiatives with the needs of the educational community, synthesising information from 39 interviews. The results show deficient channelling of the schools’ demands into municipal programmes, which are mostly planned in collaboration with third-sector entities, without the participation of the school community. It is concluded that this demand for greater participation and collaboration is one of the main demands of the school community to promote inclusion at the local level. Full article

(1) Background: Since the 1990s, theses and dissertations—a key part of scientific communication—have evolved significantly with advances in information and communication technologies. (2) Methods: This study reviews 99 publications examining these changes, drawing insights from international conferences and empirical studies in the field. (3) Results: Historically, a major challenge in managing PhD theses has been the shift to electronic formats, resulting in the creation of electronic theses and dissertations (ETDs). This shift involves four main tasks: adopting new digital formats, updating institutional workflows between departments, graduate schools, and academic libraries, implementing updated bibliographic standards (such as metadata and identifiers), and utilizing new tools and channels for distribution. With open science becoming a widespread research policy across many countries and institutions, ensuring open access for ETDs is an added challenge—though a substantial portion of ETD content remains restricted to institutional or library networks. Today, ETD management is on the brink of a new era, with advancements in data-driven science and artificial intelligence. (4) Conclusions: The development of ETDs varies significantly across different countries, regions, and institutions due to technological, organizational, and legal differences. It is essential for academic libraries and other stakeholders to address the challenges identified while considering these variations. Full article
