This study systematically synthesizes research on sustainable performance in nonprofit organizations (SPNPOs) and develops an agenda for future inquiry. Following PRISMA guidelines, we reviewed and analyzed 24 peer-reviewed articles indexed in Scopus and the Web of Science Core Collection using the Theory-Context-Characteristics-Methodology (TCCM) framework. The literature is theoretically diverse but weakly integrated, drawing on resource-based, capability, governance, stakeholder, institutional, systems, and critical perspectives. Evidence is geographically concentrated and relies predominantly on cross-sectional designs. Resource configurations, adaptive capabilities, governance mechanisms, stakeholder relationships, and institutional conditions shape sustainable performance. A persistent mission-market tension further complicates long-term sustainability. Sustainable nonprofit performance requires an integrated understanding of internal capabilities and external embeddedness. Future research should specify nonprofit-specific boundary conditions and examine how contextual pressures influence strategic decisions and performance over time. Nonprofit leaders should combine resource diversification, adaptive capabilities, effective governance, and stakeholder engagement while safeguarding mission integrity. This study provides a structured TCCM-based synthesis of a fragmented field and identifies theoretical, contextual, and methodological gaps that support a more dynamic and context-sensitive research agenda for nonprofit sustainability. It also offers a clearer foundation for theory development and comparative, longitudinal empirical research across diverse nonprofit contexts.
This study examines the associative role of crisis perception in shaping societal attitudes toward energy independence in Hungary. Drawing on quantitative results from the Green Deal survey database, the study tests the hypothesis that support for energy independence is driven primarily not by institutional trust, but by individuals’ perceived economic and social uncertainty. Statistical analysis reveals a significant relationship between crisis perception and support for energy independence (Kruskal–Wallis χ² = 10.44; p = 0.0012), while no direct explanatory effect of institutional trust can be identified (p = 0.3897). According to the regression model, subjective cost pressure and crisis perception jointly serve as significant predictors of attitudes toward energy independence (R² = 0.0745). The findings suggest that energy autonomy emerges not merely as a technological or policy preference, but as a societal response to perceived uncertainty. The study contributes to the understanding of the social dimensions of the energy transition by examining energy policy attitudes within the interrelated framework of crisis perception, social vulnerability, and energy autonomy.
Skin tissue regeneration requires wound dressing materials that are mechanically stable, highly absorbent, and biocompatible. Natural biopolymers derived from renewable and waste resources offer a sustainable approach to developing advanced nano-wound materials with enhanced healing performance. Nano-wound materials (NWMs) were fabricated using cellulose nanocrystals (CNCs), nanofibrin (NF), and chitosan nanoparticles (CNPs) through a film-casting technique. The developed NWMs were characterized using high-resolution scanning electron microscopy (HRSEM). Mechanical properties, water absorption capacity, and biocompatibility were evaluated, with cytocompatibility assessed using MTT assays on NIH/3T3 fibroblast cells. The NWMs exhibited excellent mechanical and physicochemical properties, with a tensile strength of 27.78 ± 0.46 MPa, elongation at break of 31.75 ± 0.64%, flexibility of 8.97 ± 0.91%, and water absorption of 45.71 ± 0.74%. Biocompatibility studies demonstrated high cytocompatibility, with approximately 98% cell viability observed in NIH/3T3 cells. The developed nano-wound materials demonstrated robust mechanical performance and excellent biocompatibility, indicating their suitability for skin wound-healing applications. Additionally, this study highlights a value-added and sustainable strategy for converting fish and slaughterhouse waste into functional, high-performance wound care materials.
The adoption and acceptance of mobile technologies as mobile learning (m-learning) tools in the education sector have brought benefits and opportunities in teaching and learning, especially in the 21st century. The study aims to determine the perceptions of the School Management Team members (SMT) on the use of smartphones as m-learning tools in selected secondary schools in King Cetshwayo District. The SMT members in secondary schools were targeted because they are key role players in schools in technology use and acceptance for teaching and learning purposes. The study employed a qualitative research approach to achieve the objective of this study. Ten principals were selected purposively from the selected secondary schools in King Cetshwayo District to conduct the research. Data were collected via interviews, and thematic analysis was employed. Four themes emerged: accessibility and availability, classroom integration, educational potential, and training and policies. The findings indicate that m-learning tools are essential for modern learning processes, as most SMT members recognize the potential of smartphone use to enhance student engagement and improve learning outcomes. The study recommends that adequate training should be made available to educators and that policies should be adopted and implemented for the effective integration of smartphones in secondary schools.
This study presents a comprehensive analysis, simulation, and experimental evaluation of printed Log-Periodic Dipole Array (LPDA) antennas operating within the 1-3 GHz frequency spectrum. The purpose of this investigation is to develop high-performance, wideband antenna configurations using affordable FR4 substrate technology, achieving an optimal balance between electrical performance and physical compactness. The methodology/approach involves evaluating multiple LPDA models with varying element counts (8, 10, and 13 elements) using CST Studio Suite for geometric optimization, followed by the fabrication and testing of prototypes in an anechoic chamber to validate radiation patterns and return loss. The key findings demonstrate that while increasing element count enhances gain consistency and directional stability, it introduces dimensional trade-offs. Notably, the 13-element configuration achieves a maximum realized gain of 7.4 dBi and a VSWR around 1.5 across the designated band. In conclusion, this research provides critical insights into the necessary design trade-offs for modern communication applications. The practical implications of these results offer an efficient framework for engineers to select optimal antenna configurations based on specific gain requirements and spatial constraints.
