Within the framework of consistent couple-stress theory (CCST), we develop a semi-analytical finite layer method (FLM) to investigate the three-dimensional (3D) coupled electro-mechanical behavior of an exponentially graded (EG) piezoelectric circular hollow microscale cylinder under simply supported boundary conditions. The microscale cylinder is subjected to mechanical loads and electric voltages and is placed under closed-circuit surface conditions on its outer and inner surfaces. Using the principle of stationary potential energy, we first derive a 3D Galerkin weak formulation for this study. We divide the microscale cylinder into n_l layers and select each layer’s elastic displacements and electric potential as the primary variables. We then incorporate a layer-wise generalized displacement model into the weak formulation to develop the semi-analytical FLM. The novelty of our method lies in its ability to accurately determine the electric and elastic field variables induced in the microscale cylinder. This feature has not been explored in previous research. We rigorously validate our method’s accuracy by comparing its solutions for EG piezoelectric circular hollow macroscale cylinders with the corresponding 3D solutions reported in the literature, with the material length-scale parameter set to zero. We also examine the impact of several key factors on the coupled electro-mechanical behavior of the microscale cylinder, including the radius-to-thickness ratio, inhomogeneity index, piezoelectricity, and material length-scale parameter, which appear to be significant.

This paper re-examines the problem of free will in light of both deterministic and indeterministic assumptions about the structure of the world. On the philosophical side, it analyzes van Inwagen’s arguments that free will is incompatible with determinism—because our actions would then be fixed by a remote past and the laws of nature—and with indeterminism, on the grounds that indeterministic outcomes reduce to mere chance. On the neuroscientific side, it revisits Libet-style experiments, often interpreted as showing that unconscious brain activity initiates voluntary actions before conscious intention, and critically reviews recent reinterpretations of the readiness potential and the limitations of such paradigms for assessing free will. The paper then diagnoses a shared structure in these challenges: they presuppose a strict dichotomy between Laplacean determinism and a thin, law-governed conception of chance that leaves no conceptual space for non-chance indeterminism or for agent-level causal contributions. A simple quantum thought experiment is used to show how microscopic indeterminism can have direct macroscopic effects, undermining the assumption that the macroworld is effectively deterministic. Finally, the implications of computational and dynamical models of cognition are considered, arguing that their built-in constraints should be read as limits of the models rather than as metaphysical results. The conclusion advocates a naturalistic agnosticism: current physics, neuroscience, and cognitive science neither establish nor refute free will, but underdetermine its status while still placing substantive constraints on any viable theory of it.

This paper discusses how digital transformation takes place in public knowledge institutions by examining public libraries as socio-technical service ecosystems, and conceptualizes digital maturity. Based on Service-Dominant Logic and the socio-technical systems theory, this study explores digital maturity as a natural product of convergence in technological infrastructures, professional expertise, governance mechanisms, and community involvement. The data analysis is conducted on a structured 48-item questionnaire which, at its turn, is based on a sample of 101 members of library staff in public libraries in Romania. The Romanian dataset is contextualized by using a national comparative dataset comprising 363 respondents from France. We employ a mixed method of descriptive and inferential statistical analyses and thematic coding in order to investigate institutional adaptability, AI readiness, and service development trends. The results reveal the continuing movement from collection-centered models toward hybrid physical–digital service platforms and differences in digital maturity and overall strategic planning among institutions. The results demonstrate that digital maturity is sensitive to the organized coordination and the planning capability in institutions rather than to isolated technological adoption. Drawing from this evidence, the study proposes an analytical framework and a tempered analytical lens for interpreting digital transformation processes in public knowledge ecosystems, forming a solid foundation for more general investigations of institutional adaptation to digitally mediated environments.

Factors such as asset aging, climate change affecting hydrological events, and the growing demand in electricity are placing huge pressure on hydroelectric infrastructure—in particular, hydroelectric dams, whose most important and critical component is the spillway, which operates through a system of discharge gates. This research aims to present the technical, environmental, and functional parameters and issues affecting this system, highlighting the causes of their degradation and proposing solutions to improve their service life and their reliability. A literature review has been undertaken to identify the challenges related to the reliability and durability of the system. In addition, a case study based on real-world data was made to support and reveal the problems related to the spillway gates system. What sets this research apart is its integration of theoretical studies with a practical case study, supporting the proposed theories and uncovering potential hidden factors. Following the identification of key challenges, new updated and adaptable solutions explored world-widely are recommended to be developed in future research. Full article

International graduate students studying Science, Technology, Engineering, and Mathematics (STEM) in the United States (U.S.) diversify universities and contribute to research and innovation. They are critical to the U.S. STEM pipeline, workforce and economy; therefore, it is important to understand their experiences. This systematic literature review investigated international graduate STEM students’ characteristics and the supports and barriers they experience while studying in the U.S., following PRISMA guidelines. Thirty-nine peer-reviewed articles were systematically selected from 552 articles for inclusion in this review. Ecological systems theory situated the study within the broader system of graduate education. Findings revealed great diversity, such as country of origin and cultural identity, gender, STEM fields, and prior experiences. Students expressed differences in their reasons to pursue U.S. education and their post-graduation intentions to remain in the U.S. or leave. Support came from institutions, faculty members/academic advisors, and peers. Reported barriers included unfamiliarity with norms and institutional resources, limited English proficiency and writing skills, issues with advisor and being a teaching assistant, underrepresentation, and family responsibilities. Themes were placed within the levels of the ecological framework; most were in the macrosystem, reflecting the strong influence of society, institutions, culture, and norms on students’ experiences.

As global urban centers transition into “Super-Aged Societies,” the paradigm of urban sustainability has shifted from mere housing provision to the development of Sustainable Care Retirement Communities (SCRCs). This study addresses a critical gap in the urban aging literature: the lack of culturally sensitive frameworks for social resilience in non-Western contexts. By integrating Hofstede’s Cultural Dimensions Theory, this research investigates how national culture influences the prioritization of community attributes within the “15 min city” framework. Methodologically, a hierarchical evaluation framework comprising 4 dimensions and 26 indicators was established. It employed the Fuzzy Delphi Method (FDM) to achieve expert consensus among stakeholders in Taiwan’s Long-term Care 3.0 ecosystem. Analysis using Double Triangular Fuzzy Numbers identified the “Charging Model,” “Staff-to-Resident Ratio,” and “Zoning with Care Continuity” as the highest-priority factors ($G^i$ ≥ 7.8). These results indicate that in cultures with high uncertainty avoidance, institutional financial stability and human-centric staffing are perceived as the structural bedrock of social resilience. Furthermore, the study highlights the emergence of AI-driven “Active Sensing” environments as a pivotal component of technical resilience, mitigating the loneliness epidemic while maintaining institutional efficiency. The findings suggest that social resilience in SCRCs is not merely a product of physical accessibility but is theoretically inferred by experts to be deeply rooted in the synergy of Bonding and Bridging Social Capital, rather than being a directly measured outcome. This research provides urban planners and policy-makers with a robust, evidence-based toolkit to design inclusive, resilient, and culturally aligned aging-in-place environments in the face of unprecedented demographic challenges.

This article presents preliminary research on the development of a cast iron–ceramic composite for modern braking systems, such as brake discs. The composite matrix is gray cast iron with flake graphite (EN-GJL-150). The reinforcing phase is a porous ceramic composed of SiC and Al₂O₃ particles introduced separately (10% each) and together (70% SiC + 30% Al₂O₃). These particles were applied as a suspension onto polyurethane foam, yielding a ceramic structure with a pore density of up to 10 ppi. The resulting insert was placed in a mold cavity, and cast iron was poured into it. The resulting samples were treated as brake disc material, with a pad made of the commercial friction material P50094 serving as the countersample. Tribological tests showed that the lowest sample wear (average 2.23 mg/5000 m) was achieved for the composite reinforced with SiC + Al₂O₃ particles. This is probably due to the synergy between the antifriction properties of these particles and the lower friction coefficient (µ = 0.180–0.22). Similar mass loss values and the smallest difference between the tested samples were observed for composites with SiC particles (3.01 mg/5000 m) and Al₂O₃ (3.30 mg/5000 m). The second part consisted of microstructural studies. Microstructural analysis of the EN-GJL-150 + SiC + Al₂O₃ composite revealed a previously unobserved nucleation phenomenon at the cast iron–ceramic interface. This confirmed the general assumptions of Riposan’s theory regarding the involvement of oxide microinclusions and complex manganese sulfides of the (Mn, X)S type in the nucleation and crystallization of graphite precipitates. It was also found that, in the case of “in situ” GJL-150 + SiC + Al₂O₃ composites, this theory should account for the beneficial role of ceramic particles in promoting the uniform distribution of type A graphite flakes, which nucleate on their surfaces in the transition zone. Thus, the nucleating role of oxide microinclusions (the first stage of Riposan’s theory) could be taken over by SiC and Al₂O₃ particles, constituting a substrate for the heterogeneous nucleation of (Mn, X)S sulfides.

Mandatory Environmental, Social, and Governance (ESG) disclosure requirements—anchored in Corporate Sustainability Reporting Directive (CSRD), International Sustainability Standards Board (ISSB), and Task Force on Climate-related Financial Disclosures (TCFD)—have placed unprecedented demands on supply chain data quality and auditability. Blockchain technology, combining immutability, decentralised governance, and smart contract automation, has emerged as a candidate infrastructure for addressing verification deficits across multi-tier supply chains. To our knowledge, no prior systematic review has simultaneously examined the blockchain specifically for formal ESG transparency and sustainability reporting across all three ESG dimensions within the post-CSRD mandatory reporting landscape. This study presents a systematic literature review (PRISMA 2020). Scopus and Web of Science searches identified 1,166 records (2016–2026); after deduplication, 761 unique records were screened, and after blinded screening (κ = 0.84), 96 studies were included. Five blockchain application typologies are identified (T1–T5), spanning provenance tracing, smart contract compliance, carbon accounting, supplier data aggregation, and ESG disclosure systems. A structural asymmetry is identified: governance is addressed in 96% of studies (77.1% under the strictest G-CONFIRMED recoding; 95.8% under the moderate interpretation, including borderline cases), the environmental pillar in 49%, and the social dimension in 21%, explained through institutional theory, with significant implications for CSRD and Corporate Sustainability Due Diligence Directive (CSDDD). Key barriers include scalability, interoperability, and the blockchain–GDPR (General Data Protection Regulation) tension. Three principal contributions are made: (i) a systematic typology of blockchain for ESG transparency; (ii) institutional-theory explanation of ESG dimension asymmetry; and (iii) a research agenda centred on AI–blockchain convergence and post-CSRD empirical studies. The review is limited to English-language peer-reviewed literature. Full article

Approaching the tension between critical thinking and religious conviction in a modern secular context, this study explores Paul Ricoeur’s theological hermeneutics as a potential metaphoric language for doing contemporary theology. Utilizing Ricoeur’s hermeneutic method of the “long route”—a patient detour through text, symbol, and narrative that refuses the direct existential decoding of myth—the research qualitatively analyzes his interdisciplinary insights across biblical interpretation, revelation, and narrative theory. The analysis reveals that Ricoeur’s integration of philosophical and biblical hermeneutics facilitates what he calls a “second naïveté”: a post-critical posture in which religious symbols can be inhabited again only after, and through, the labour of critique, never before or around it. Such a posture addresses the specifically modern difficulty of making Christian faith argumentatively responsible to contemporary readers, believers and reflective non-believers alike. Key findings highlight the poetic dimension of theological language—its capacity to disclose rather than merely describe—as essential for reconfiguring reality and for redefining revelation as an event that takes place between the “world of the text” (the possible world projected by a biblical text read as discourse) and the “world of the reader.” This reorientation does not dismiss dogmatic-theological formulation; it holds the systematic–speculative and the poetic–hermeneutic together rather than letting either collapse into the other. The study concludes that doing theology through metaphor—specifically through the dialectic between “being” and “being-as” of God—opens a generative hermeneutic perspective for articulating the divine in a post-critical age, where the category “post-critical” designates not a repudiation of critique but the reflective stance that remains possible only on the far side of it. Rather than providing a unified theological system, this perspective preserves the tensions—between philosophy and theology, critique and conviction, metaphor and its ontological reach—that Ricoeur deliberately leaves unresolved.

Under wartime conditions, conceptual approaches to organizing the education system are changing, and the means of achieving goals are being modified. All of this affects the development of infrastructural provision for the educational network and simultaneously requires adequate management. The state, as the main subject of social management, employs management theory and practice of competent (professional) business leadership. This approach not only allows it to survive but also to develop in the objectively existing competitive environment. It has been determined that the main elements of educational management (EM) organization include the quality of intellectual resources, analysis of internal and external environments, analysis, selection and implementation of educational system (ES) development strategies and evaluation and control of their execution. Attention is focused on forming an ecologically oriented society through the lens of knowledge transfer, with a focus on the irrational use of natural resources across various spheres of human activity, energy resource deficits, and sustainable development tasks in Ukraine. A central place in this process is assigned to organizing project activities and to forming an ecologically oriented worldview among future specialists trained by educational institutions at various levels and forms of ownership. The analysis of educational management (EM) models shows that the project-investment model remains relevant. Trends in quantitative indicators of EM and ecological projects in Eastern European countries have been analyzed, based on which conclusions have been formulated that reflect the current state of ecological education development and demonstrate existing changes, challenges, and prospects. A visualized flowchart of optimizing the organization of higher education through the prism of an environmentally friendly society has been developed, with four blocks highlighted: methodological, organizational, analytical, and resultant. It has been determined that knowledge transfer from universities to communities should become a priority in the state’s post-war reconstruction, ensuring the socio-economic development of regions, including strengthening Ukraine’s energy independence. The practical significance of the obtained results lies in developing recommendations for implementing the integration of educational management (new functions) and project activities in educational institutions, which can be used when forming their development strategies, establishing international partnerships in the educational sphere, as well as for developing state programs to support the development of Ukraine’s economic, ecological, and social policy.

Constructing age-friendly residential environments is essential for supporting aging in place among the growing population of urban empty-nest older adults in China. Grounded in person–environment fit theory, this study developed and validated a multidimensional Aging-Suitability Index (ASI) to examine how residential environmental factors shape housing suitability and perceived independence. In this study, “aging suitability” refers to the degree of fit between residential environments and older adults’ needs for safety, functionality, accessibility, social support, and technological support, with the central aim of enabling aging in place and independent living. Questionnaire data were collected from 753 urban empty-nest older adults across 19 provinces in China and analyzed using partial least squares structural equation modeling (PLS-SEM). The structural model showed strong explanatory power (R² = 0.754). The results revealed a clear hierarchy of environmental influences. Safety facilities and physical design were the strongest direct predictors of residential aging suitability, indicating that risk reduction and ergonomically appropriate spatial design constitute the foundation of age-friendly housing. Although accessibility showed a smaller direct effect, it exerted a significant indirect effect through perceived independence, with 67.35% of its total effect mediated through this pathway, highlighting the importance of barrier-free design in maintaining autonomy. Social support and smart technology also contributed positively as complementary resources that strengthened person–environment fit. These findings suggest that age-friendly housing interventions should move beyond fragmented modifications toward integrated residential renewal strategies that prioritize safety and physical design, improve accessibility to support independent living, and combine community support with age-friendly technologies. This study provides empirical evidence to inform built-environment decision-making in the design and renewal of housing for older adults in rapidly aging urban contexts. Full article

In smart construction, identifying the competencies required of engineering–procurement–construction (EPC) safety directors is important for improving personnel selection, training, and safety-governance effectiveness. Drawing on dynamic capabilities theory, this study develops an exploratory competency framework for EPC safety directors in smart-construction contexts. A mixed-method design was adopted, combining a structured literature review, bibliometric mapping with CiteSpace, semistructured interviews, expert review, and questionnaire-based item screening. Questionnaire data from 189 valid respondents were analyzed using descriptive statistics, item analysis, Cronbach’s alpha, and KMO/Bartlett tests to preliminarily assess the internal consistency and structural suitability of the proposed indicators. The results indicate that the retained exploratory framework comprises three higher-order dimensions—sensing, seizing, and reconfiguring—covering six competency elements and eighteen indicators after the remaining trend-sensing indicator was integrated into data analytics. Compared with conventional safety-management competency frameworks, the proposed framework places greater emphasis on data analytics, intelligent systems application, and cross-departmental coordination in digitally enabled project environments. The framework can be implemented as a role-profile template for recruitment, training-needs diagnosis, and performance appraisal of EPC safety directors, while further empirical validation is required before it is used as a standardized measurement scale.

Career development spans higher education through post-entry adaptation, retention, and transition. Organizational career management (OCM) links human resource management, career attitudes, and employability, yet lacks a coherent account of how organizational provisions become concrete developmental experience in daily work. This article re-specifies OCM as a developmental system comprising four layers: OCM as superordinate architecture, developmental HR practices as implementation infrastructure, developmental networks as a relational access layer, and proactive career behaviors/career self-management (CSM) as self-regulatory behaviors conditioned by institutional and relational support. The central contribution is proposing collective leadership behaviors (CLB) as a candidate for specifying the missing workplace-practice layer. Developmental networks explain who employees turn to for support; CLB explains how support is enacted in team interaction so that organizational provision becomes developmentally usable. CLB is treated not as shared leadership or a substitute for supervisor support, but as enacted workplace practice once institutional provision and relational access are in place. Because empirical studies linking CLB to career development remain limited, this framework advances as a theory-building integrative review: developmental networks matter most when the bottleneck is access to heterogeneous support, whereas CLB matters most when support exists but is not yet enacted as usable developmental experience.

Against the backdrop of the growing emphasis on cultural confidence and the continuous expansion of cultural consumption, how local museums effectively transform local cultural resources into cultural and creative consumption behavior has become an important research issue. Taking the Luoyang Museum as the empirical context, this study integrates Place Attachment Theory (PALT) with the Stimulus-Organism-Response (S-O-R) framework to construct a research model of “place attachment–cultural participation–perceived authenticity/experience satisfaction–behavioral intention.” Based on 182 valid samples, Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed for empirical analysis. The results indicate that place attachment significantly and positively influences cultural participation; cultural participation significantly and positively affects experience satisfaction, perceived authenticity, and behavioral intention; experience satisfaction significantly enhances perceived authenticity; and perceived authenticity significantly promotes behavioral intention. Further analysis reveals that cultural participation plays a significant mediating role between place attachment and experience satisfaction, perceived authenticity, and behavioral intention. Perceived authenticity serves as a key mediator between cultural participation, experience satisfaction, and behavioral intention. In addition, multiple serial mediation paths, such as “cultural participation–experience satisfaction–perceived authenticity–behavioral intention,” are found to be significant. The findings demonstrate that place attachment does not directly translate into cultural consumption behavior, but instead operates through cultural participation to activate authenticity perception and experiential evaluation, which in turn influence behavioral intention. This study enriches the application of Place Attachment Theory and the S-O-R framework in the context of museum cultural consumption and provides both theoretical support and practical implications for enhancing the transformation capacity of cultural and creative products in local museums. This study enriches the application of Place Attachment Theory and the S-O-R framework in museum cultural consumption research and provides theoretical support and practical implications for enhancing the transformation capacity of cultural and creative products in local museums, particularly in promoting sustainable cultural consumption.

With the rapid development of immersive digital technologies, location-based entertainment (LBE) exhibitions have emerged as a new medium for cultural dissemination, particularly in cross-cultural contexts. While prior research on immersive experiences has predominantly emphasized immersion and virtual presence, limited attention has been paid to how audiences develop a sense of place within digitally constructed, culturally foreign environments. Drawing on sense of place theory and environmental psychology, this study develops the concept of cross-cultural virtual sense of place and proposes an S–O–R framework to examine the psychological mechanisms underlying immersive experiences. Specifically, entertainment, education, aesthetics, and escapism are conceptualized as stimuli (S), perceived restoration and place attachment as organism states (O), and continued engagement intention as the behavioral response (R). Data were collected from 383 participants who experienced an LBE immersive digital exhibition in China. Structural equation modeling (SEM) results indicate that escapism has the strongest effect on perceived restoration, followed by education, entertainment, and aesthetics. Perceived restoration significantly enhances place attachment and continued engagement intention, and place attachment partially mediates the effect of perceived restoration on continued engagement intention. The findings contribute to the literature by reframing immersive digital exhibitions as processes of experiential place-making rather than mere content delivery, and by identifying perceived restoration as a critical psychological pathway linking immersive stimuli to sustained engagement in cross-cultural digital environments.
