The purpose of this study is to propose and test an integrated model to explain how trust is built in sharing economy (SE) transactions.

Initially, prior literature was systematically selected and synthesized to develop a comprehensive framework applicable to multiple trust-building perspectives and categories of SE platforms. Then, a survey was conducted to validate the constructs and test the model with Airbnb guests. A sample of 351 responses was collected and analyzed using structural equation modeling.

The results indicate that the cues an individual assesses to infer their counterpart’s trustworthiness and the reasons the individual has for engaging in the SE transaction can explain a large variance in their trust in the counterpart. In addition, the individual’s propensity to trust moderates this relationship.

The proposed model can help identify the most effective trust-building mechanisms. It can be taken as a common knowledge base for scholars to compare the four trust-building perspectives and different categories of SE platforms, as well as to investigate the subject over time and across cultures.

This research can also help practitioners understand the complexity of building trust and design platform features to do so.

A unified model clarifies trust in the SE, aiding platform growth and community bonding. This insight guides platforms in feature enhancement and policymakers in drafting balanced regulations.

To the best of the authors’ knowledge, for the first time, there is a comprehensive and parsimonious model applicable to the four trust-building perspectives and different categories of SE platforms.

This study aims to address the effects of self-esteem and affective commitment on firm performance and whether these effects vary according to the gender and age of active entrepreneurial students.

This study uses a subsample from the Global University Entrepreneurial Spirit Students’ Survey (GUESSS) of entrepreneur students running their own businesses to perform a structural equation model (SEM) analysis to test the relationship between self-esteem (SE), affective commitment (AC) and firm performance (FP) moderated by the gender and age of entrepreneur students.

The results confirm that higher levels of entrepreneur SE are related to a higher assessment of AC and FP. A major effect of SE on AC was also observed among male respondents. Age was not related to an increase in AC. The effect of SE on AC and FP was lower among older students.

This study makes valuable contributions to the fields of entrepreneurship, psychology, gender and organizational behavior. This study presents empirical support for the theoretical framework using SEM, presenting initial insights into the mechanisms that shape AC in entrepreneurial students and its implications for FP.

Esta investigación tiene como objetivo analizar la influencia del género, la edad y la autoestima (SE) de los emprendedores en el compromiso afectivo (AC) de los estudiantes universitarios con sus emprendimientos y cómo se relacionan con el desempeño subjetivo de la empresa (FP).

Utilizamos los datos de la encuesta GUESSS de 2018 para realizar un modelo de ecuaciones estructurales (SEM) para determinar los efectos directos del género, la edad y la SE en el AC, sus efectos directos e indirectos en el FP y los efectos directos y papel mediador del AC hacia el FP, para estudiantes emprendedores.

Los resultados confirman que niveles más altos de SE están relacionados con niveles más altos de AC de los emprendedores a sus emprendimientos y una mayor evaluación de FP. Además, los hombres reportan niveles más altos de AC y FP que sus contrapartes femeninas, al tiempo que el género tiene un efecto importante en la relación del SE en el AC. La edad no está relacionada con el aumento del AC, pero el efecto de la SE sobre el AC disminuye con el incremento de la edad, y los valores de FP también se reducen para los estudiantes mayores en comparación con los estudiantes más jóvenes. Los niveles más altos de AC están relacionados con valores más altos de FP, y existe un efecto de mediación de AC para el género y SE sobre FP.

Primero, presentamos un marco teórico que integra postulados de emprendimiento FP, AC, SE, edad y género. Luego, probamos empíricamente nuestro marco teórico utilizando SEM y presentamos resultados iniciales sobre los mecanismos que dan forma al AC en estudiantes emprendedores y sus implicaciones para el FP.

Esta pesquisa tem como objetivo analisar a influência do gênero, da idade e da autoestima (SE) dos empreendedores no comprometimento afetivo (AC) dos universitários com seus empreendimentos e como eles se relacionam com o desempenho subjetivo da empresa (FP).

Utilizamos dados da pesquisa GUESSS de 2018 para realizar uma modelagem de equações estruturais (SEM) para determinar os efeitos diretos de gênero, idade e SE na AC, seus efeitos diretos e indiretos no FP e os efeitos diretos e papel mediador do AC na FP, para estudantes empreendedores.

Os resultados confirmam que níveis mais elevados de SE estão relacionados com níveis mais elevados de AC dos empreendedores para os seus empreendimentos e uma maior avaliação do FP. Além disso, os homens relatam níveis mais elevados de AC e FP do que as mulheres, embora tenham um efeito importante da SE na AC. A idade não está relacionada com o aumento da AC, mas o efeito do SE na AC diminui com o aumento da idade, e os valores de FP também diminuem para os alunos mais velhos em comparação com os alunos mais jovens. Níveis mais elevados de AC estão relacionados a valores mais elevados de FP, e há efeito mediador da AC para gênero e SE sobre FP.

The purpose of this paper is to explore the influence of hole on shielding effectiveness (SE) of electromagnetic shielding (EMS) fabric under incident polarization wave, and to propose a “Key Size” theory to explain the influence mechanism.

“Key Size” parameters describing hole shape are established, and a number of representative samples with rectangular and oval holes are made. SE of the samples are tested by waveguide testing system. Influence of the hole on the SE of the samples is analyzed according to vertical or horizontal maximum size and polarization wave direction. Finally, the “Key Size theory” and “Secondary Size theory” are proposed to explain the influencing mechanism.

The hole influences on the SE are related to the vertical and the horizontal maximum size of the holes and the direction of the polarization wave. As the direction of the polarization wave is vertical (or horizontal), greater maximum size results in lower SE. As the maximum size is constant, greater maximum size causes lower SE. As the maximum size reaches to a certain value, a dividing point of the SE occurs. As the direction of the polarization wave is consistent with the direction of the maximum size, same hole area results in same SE.

The explored influences and mechanism provide an important guiding reference for the hole design of the EMS fabric, and can be applied to the holes design of the EMS garment, composite materials, and tents.

The optimization of variable thickness plates and shells is studied. In particular, three types of shell are considered: hyperbolic paraboloid, conoid and cylindrical shell. The main objective is to investigate the optimal thickness distributions as the geometric form of the structure changes from a plate to a deep shell. The optimal thickness distribution is found by use of a structural optimization algorithm which integrates the Coons patch technique for thickness definition, structural analysis using 9‐node Huang‐Hinton shell elements, sensitivity evaluation using the global finite difference method and the sequential quadratic programming method. The composition of the strain energy is monitored during the optimization process to obtain insight into the energy distribution for the optimum structures. Several benchmark examples are considered illustrating optimal thickness variations under different loading, boundary and design variable linking conditions.

This study aims to assess the alignment of South Korea’s government-certified social enterprises (GCSEs) with prevailing social enterprise (SE) models, notably the entrepreneurial nonprofit, social cooperative and social business models delineated in the “Emergence of Social Enterprises in Europe” (Defourny and Nyssens, 2012, 2017a, 2017b) and the “principle of interest” frameworks (Defourny et al., 2021). Thereby, it seeks to situate these enterprises within recognized frameworks and elucidate their hybrid identities.

Analyzing panel data from 2016 to 2020 for 259 GCSEs, this study uses tslearn for k-means clustering with dynamic time warping to assess their developmental trajectories and alignment with established SE models, which echoes the approach of Defourny et al. (2021). We probe the “fluid” identities of semi-public sector SEs, integrating Gordon’s (2013) notion that they tend to blend various SE traditions as opposed to existing in isolation.

Results indicate that GCSEs do align with prevalent SE frameworks. Furthermore, they represent a spectrum of SE models, suggesting the versatility of the public sector in fostering diverse types of SEs.

The concept of a semi-public sector SE model has been relatively uncharted, even though it holds significance for research on SE typologies and public sector entrepreneurship literature. This study bridges this gap by presenting empirical evidence of semi-public SEs and delineating the potential paths these enterprises might take as they amalgamate various SE traditions.

The integration of digital technologies into education has brought about a profound transformation, fundamentally reshaping the learning landscape. The purpose of this study is to underscore the importance of investigating the factors influencing students’ engagement (SE) in this evolving digital era, particularly within formal digital learning environments. To address this need, the study is grounded in self-determination theory (SDT) and presents a comprehensive model comprising interconnected elements: digital competence (DC), smartphone use (SPU), perceived autonomy (PA), digital formal learning (DFL) and SE.

The research conducted an investigation within Saudi Arabian universities, collecting a robust data set of 392 cases. This data set underwent rigorous analysis to validate the proposed model. To untangle the intricate relationships within the framework, the study used partial least squares structural equation modelling. Given the distinct dimensions of the two constructs under study, the researcher used a disjoint two-stage approach to establish reflective-formative higher-order constructs (HOC).

The findings revealed that digital literacy and digital skills (DS) constitute the foundational constituents of DC. Simultaneously, the study identified facilitation, distraction and connectedness as integral components of SPU. Importantly, the study established that DC, SPU, PA and DFL significantly influence SE. Furthermore, the research illuminated the mediating roles played by SPU, PA and DFL in the complex relationship between DC and SE.

This study advances the literature by delineating the dynamic interplay between DC, SPU and SE in digital learning. It extends SDT within educational contexts, emphasizing the role of internal motivations and DS. Methodologically, it innovates through reflective-formative HOCs, deepening the analysis of complex educational constructs. Managerially, it guides institutions in enhancing DC and integrating smartphones effectively into learning, advocating for tailored strategies to foster engaging and autonomous digital learning environments, thereby enriching both theoretical understanding and practical application in education.

Social entrepreneurship (SE) has become the engine propelling the rapid expansion of the social/environmental sector; thus, the authors need to examine it from different perspectives. First of all, it is vital to understand the concept of SE in an attempt to understand the most basic question: what makes an entrepreneurship social and what makes a social initiative a SE? Second, it is important to know the tools to develop a SE such as the business model canvas and design thinking, among others, which are adapted to SE, as well as tools that are unique to the sector such as impact measurement and impact investing. Third, aspiring SEs have to understand the current ecosystem in order to take advantage of the enormous support that the SE ecosystem has to offer thanks to global players such as Ashoka, the Schwab, and Skoll foundations as well as prominent Latin American players such as New Ventures Group, ANDE, and collective company-driven initiatives such as Momentum led by BBVA Bank that have supported more than 10,000 SE all over the world. Finally, the authors will introduce the case of low-income house builders Hábtiva and a student challenge to ignite aspiring social entrepreneurs. This chapter provides a glimpse of the field SE by focusing in its importance in our current challenging world, its definition, some tools used in the field, the current ecosystem of SE, how to measure social impact, and some cases and challenges.

In this book chapter, we analyse social entrepreneurship (SE) development in the Western Balkans and present a regional overview. SE has become a globally known contributor to alleviating societal, economic, social, and environmental concerns. Its influence on increasing people’s quality of life has put the concept on a pedestal, and the Balkans are no different. The new advances have increased the efforts from the third sector in advocating for increased visibility, recognition, and support for social enterprises (SEs) as contributors to the development of resilient communities and facilitating the countries’ recovery from economic, social, and environmental crises. To provide a regional development overview, we use the institutional perspective. We base the analysis on data by applying qualitative methods, including document analysis, conference speeches, round tables, consultations, and other impactful events conducted over the last decade. The evidence suggests that the Western Balkan countries are similar in their development and lack a clear vision, a strategic pathway, and sustainable solutions to accelerate the sector’s growth. The awareness of the SEs’ contributions is still low, hindering their impact and potential scalability. Raising awareness campaigns is much needed to increase SEs’ visibility, recognition, revenues, and financial sustainability. Intersectoral collaboration is not at a suitable level, and the coordination and partnerships between the SE actors are lacking. The region needs to make a significant and consistent effort to facilitate the sector’s development and support SEs to provide the expected societal impact.

The purpose of this study is to look at the factors that drive people to participate in the sharing economy (SE). Based on the Technology Acceptance Model (TAM) and the Theory of Planned Behavior (TPB), the study proposes a mathematical model. The study’s ultimate objective is to help businesses attract more involved customers and promote collaborative consumption as a sustainable alternative to typical consumption patterns. The study offers a conceptual framework established via a thorough literature review to examine Indian customers’ use behavior toward SE platforms. A one-sample two-tailed t-test is used to assess the framework’s efficacy. The research fills gap in the literature on the SE by investigating the factors that determine subjective norms (SN), attitudes (A), and perceived behavioral control (PBC). A framework is provided that takes behavioral intention (BI) contemplated as a mediating variable. The research improves TAM and TPB by including new factors such as technical characteristics. This research adds to the body of knowledge on the digital SE by underlining the relevance of usage behavior in comprehending Indian customers, where A, SN, and PBC are important aspects. The research presents a paradigm for better understanding customers’ attitudes and behaviors toward various SE platforms, which might help academics, practitioners, and policy makers situate their initiatives within the larger field of sharing. The study’s categorizations of Indian consumers’ A, SN, PBC, and BI toward the SE might potentially advise on future research and government policies.
