Background: There exists a scarcity of comprehensive studies on educational campuses, which integrate the effects of built environment satisfaction, university life experiences, and personal characteristics on QoL. The study’s main research problem is to investigate the extent, direction, and sequence of the influence of university life satisfaction (encompassing academic, social, and administrative perception)—as well as the university’s built environment of university (including both indoor and outdoor attributes of educational, social, recreational, and residential settings), in conjunction with student characteristics—on students’ QoL and the interactions among these factors. Aim: The main objective is to comprehensively analyze the impact and dominance of the built environment and various dimensions of university life, in addition to personal variables on student QoL, and explore the interaction between them. The sub-aims are to determine the dimensions that have the greatest effect on QoL and to make comparisons between them. Methodology: In line with the aim, a specific index for measuring student QoL on a university campus was developed, and a survey was conducted using a questionnaire developed based on the index. The case study is made in Bursa Uludag University, one of the oldest universities in Bursa, Turkey, which is known for being included in the UNESCO World Heritage List. Data were recorded and analyzed by utilizing statistical analyses via SPSS (statistical package for social sciences) for Windows 22 and IBM AMOS 24.0 programs. Results: The data collected from the evaluation of questionnaires administered to 685 participants reveal that the sub-dimensions with the most-to-least impact on students’ QoL are satisfaction with campus life, education spaces, academic development, socio-physical amenities, social perception, administrative management, accessibility, transportation, and accommodation. Conclusions: QoL is a multidimensional judgment through which university students’ QOL perceptions are affected through the interaction between the university’s built environment, university life, individual characteristics, as well as administrative management.

As new urbanization and rural revitalization strategies are implemented, the relationship between urban and rural areas is rapidly changing. Accordingly, rural landscape design is becoming increasingly important for promoting rural development. Located at the intersection of urban and rural areas and offering unique geographic characteristics and developmental potential, urban–rural fringe villages offer a valuable setting for assessing how rural transformation and landscape improvement influence the settlement intentions of regional talents. Drawing upon the Landscape Affordance Theory and the Stimulus–Organism–Response Theory, this study develops a model to evaluate how enhancements in comfort, convenience, safety, and aesthetics within rural landscapes influence the perceptions of livability and settlement intentions of young rural talents. The research utilizes a survey of residents aged 16 to 45 in representative urban–rural fringe villages in Nanjing, Jiangsu Province, collecting 230 valid responses. Data analysis was performed using SPSS 26 and AMOS 28 to assess the impact of these landscape attributes on livability perceptions and settlement intentions. This study demonstrates that Perceived Convenience (PCV) and Perceived Aesthetics (PA) have significant positive effects on Design Satisfaction (DS) and Perceived Livability (PL). The research identifies the positive impacts of the four characteristics of rural landscape enhancement on PL, ranking them in order of influence: PCV > PA > Perceived Safety (PS) > Perceived Comfort (PC). Similarly, the positive effects on DS are ranked as follows: PCV > PA > PC. PL is identified as having the strongest impact on Talents’ Intention to Stay (TIS), indicating that improving livability perceptions is crucial for enhancing both design satisfaction and settlement intentions. Our findings demonstrate that improvements to the convenience, comfort, aesthetics, and safety of the landscape environment can significantly affect the settlement intentions of young talents in rural areas. Through field research and empirical data validation, this study highlights the positive effect of enhancements in four key areas of landscape design on the perceived livability and settlement intentions of young talents in rural settings, offering clear guidance for rural planning and design initiatives.

This research leverages insights from both social cognitive theory (SCT) and stimulus-organism-response theory (S-O-R) to investigate how digital entrepreneurship education (DEE) influences undergraduate students’ digital entrepreneurial alertness (DEA), motivation (DEM), and intentions (DEI). The main objective of the study was to examine whether individual levels of DEA and DEM independently and sequentially mediate the relationship between DEE and DEI. To collect the data, convenience sampling was utilized, involving 221 students from a single public university in Saudi Arabia, and a theoretical model was examined utilizing structural equation modelling (SEM) techniques in SPSS AMOS (Version 27). The results found that DEE had a significant positive impact on students’ DEIs, DEA had a significant positive impact on students’ DEI, and DEM had a significant positive impact on students’ DEI. Moreover, the results of the serial mediation analysis indicated that DEA and DEM served as independent and sequential mediators in the relationship between DEE and DEI. These findings provide further insight into the association between DEE and DEI, offering valuable implications for both entrepreneurship education curriculum developers and government policymakers. This study adds substantial contributions to the existing literature on entrepreneurship education and DEI. Full article

Drawing on the social capital theory, the research examines the impact of network size, network centrality, trust, and regulation on the knowledge integration and robustness of emergency medical logistics. Additionally, the research seeks to provide deeper insight into the link between the variables by studying how knowledge integration mediates the relationship between independent variables and the robustness of emergency medical logistics. The study utilized structural equation modeling to assess the underlying assumptions of the research model. A total of 465 valid questionnaires were collected from government departments, hospitals, social teams, and enterprises. The data processing and analysis were conducted using SPSS 23.0 and AMOS 24.0 software. The study’s outcome indicated that network size and network centrality have indirect effects on the robustness of emergency medical logistics through the intermediate variable of knowledge integration, but neither has a direct effect. Moreover, knowledge integration has a significant positive impact on the robustness of emergency medical logistics. Both trust and regulation have positive effects on the robustness of emergency medical logistics, and they also have positive effects on the robustness of emergency medical logistics through knowledge integration. This study is the inaugural exploration of the correlation between knowledge integration and the robustness of emergency medical logistics. It adds to the literature by providing evidence that knowledge integration is an essential emergency organization’s aide in promoting the robustness of emergency medical logistics. The findings of this study establish a strong theoretical foundation and practical significance for ensuring and improving the level of effectiveness in emergency medical logistics management.

This study leveraged the social exchange theory to explore the influence of the knowledge management cycle on employee engagement, job satisfaction, and organizational culture within the Ghana Highway Authority (GHA). The structural equation modeling (SEM) software (AMOS version 23) was employed to analyze data from 300 GHA employees. The study used snowball sampling and a descriptive cross-sectional methodology to collect data through printed and electronic questionnaires. The findings demonstrated a substantial and positive impact of the knowledge management cycle on employee engagement, job satisfaction, and organizational commitment. Employee engagement also exhibited a significant and positive influence on both job satisfaction and organizational commitment. Furthermore, employee engagement partially mediated the relationships between the knowledge management cycle, job satisfaction, and organizational commitment. This study’s findings underscore the practical implications of allocating resources to knowledge management activities. Such allocation can promote organizational culture and employee satisfaction, enabling firms to achieve real gains. Full article

This study explored the determinants of sustained participation in new sports by applying the Theory of Planned Behavior (TPB) and examining the moderating role of social support, as well as the influence of media interest. This present study aimed to contribute to the promotion and effective adoption of new sports by providing valuable data for new-sports educators to teach these activities. A survey was conducted among 313 university students enrolled in new-sports classes across five universities in Korea, utilizing a convenience sampling method. Using SPSS 26.0 and AMOS 26.0, we conducted frequency, correlation, and reliability analyses, followed by confirmatory factor analysis (CFA) to validate the measurement model and structural equation modeling (SEM) to examine the relationships between media interest, attitudes, subjective norms, perceived behavioral control (PBC), and behavioral intentions. The software Jamovi version 2.3.21 was employed to analyze the moderating effects of social support from educators on these relationships. The findings reveal that media interest significantly influenced the attitudes, which, in turn, along with subjective norms and PBC, affected the behavioral intentions. Moreover, the social support from educators moderated the effects of attitudes, subjective norms, and PBC on the behavioral intentions. This study concluded that leveraging media interest and enhancing social support can effectively promote engagement and sustained participation in new sports. These insights can offer practical strategies for stakeholders aiming to increase participation rates in new-sports activities. Full article

Video blogging channels for social media technology continue to innovate and evolve, and brands are beginning to rely on social media channels for product marketing. The factors influencing consumers’ purchase intention for products advertised by video bloggers are numerous and unclear. The main purpose of this study is to explore the mechanism by which the characteristics of video bloggers influence the formation of emotional cognition and then influences consumers’ purchase intention. Based on the SOR model, 518 questionnaires were administered to Chinese video blogging users. The AMOS 24.0 and SPSSAU 24.0 web tools were used to analyze the study data. Empirical results indicate that consumers’ perceived homogeneity, expertise, degree of emotional attachment to video bloggers, and perceived source confidence have a direct or indirect positive influence on purchase intentions. Evident advertising intention weakens the relationship between emotional attachment and purchase intention. This result is strategically important for a brand’s advertising efforts and market share and provides new research insights and frameworks for studying consumers’ advertised product purchase behaviors in the context of video blogging channels for social media.

Background: The goal of our research was to determine the effects of plant-based dietary patterns on sleep health among older adults and to examine the parallel mediated effects of anxiety and depression. Methods: This investigation utilized data obtained from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS) and contained 6853 participants. Logistic regression and the restricted cubic splines (RCSs) model were employed to examine how plant-based dietary patterns affect sleep health. Additionally, Amos 26.0 was used to construct a structural equation model to examine the parallel mediated effects of anxiety and depression. Results: A higher plant-based diet index (PDI) was connected to higher odds of better sleep quality (OR = 1.209, 95% CI: 1.039–1.407) and sleep duration (OR = 1.241, 95% CI: 1.072–1.437). Conversely, an elevated unhealthy plant-based diet index (uPDI) was correlated with a lower likelihood of sleep quality (OR = 0.678, 95% CI: 0.574–0.800) and sleep duration (OR = 0.762, 95% CI: 0.647–0.896). The RCSs regression further identified a significant dose–response relationship. Mediation analysis confirmed that anxiety and depression partially mediate the relationship between plant-based diets and sleep health. Conclusions: Our study exhibited significant correlations between plant-based diets and sleep health in the elderly. Depression and anxiety were determined as parallel mediators between plant-based diets and sleep health. Controlling early dietary patterns and affective disorder could help improve sleep quality in older adults. Full article

Background/Objectives: The triple jump is included in the Paralympic Athletics competition. The aim of the research was to examine the relationship of the phase ratios and the inter-limb asymmetry in the spatiotemporal parameters of the approach run in Paralympic and international-level Class T46/T47 triple jumpers. Methods: Eleven Class T46/T47 male athletes were recorded during the examined competitions. Step length (SL), frequency (SF), and average velocity (ASV) for the late approach run as well as the length and the percentage distribution of each jumping phase (hop, step, jump) were measured using a panning video analysis method. The inter-limb asymmetry was estimated using the symmetry angle. Results: No significant inter-limb asymmetry was found (p > 0.05). In addition, SL, SF, and ASV were not different (p > 0.05) between the steps initiated from the ipsilateral and the contralateral leg regarding the impaired arm. However, the direction of asymmetry for SF was towards the ipsilateral leg to the impaired arm in the majority of the examined athletes. The maximum speed of the approach was correlated with the triple jump distance and the magnitude of asymmetry for AVS was correlated with the vertical take-off velocity and angle for the step. Conclusions: Since the distance of the triple jump related with the peak approach speed added the negative correlation of peak approach speed with the magnitude of the symmetry angle for SL, it is suggested to minimize the asymmetries in the step characteristics during the approach run to improve triple jump performance in Class T46/T47 jumpers.

This study aims to evaluate the representativeness of Calibration/Validation (Cal/Val) sites for satellite data, develop a framework for establishing new Cal/Val sites, and propose a heterogeneity index to be applied within this framework, specifically focusing on South Korea. The proposed framework assesses the representativeness of existing Cal/Val sites, and, if found inadequate, provides a methodology for optimizing the location and number of additional Cal/Val sites, along with a prioritization strategy for their installation. Furthermore, the framework includes a methodology for evaluating the suitability of utilizing existing ground observation networks as additional Cal/Val sites and for prioritizing their use. The heterogeneity index is derived by synthesizing differences in geographic, climatic, vegetation, and spectral characteristics between the current Cal/Val sites and the broader regions. A higher heterogeneity index indicates significant divergence from existing Cal/Val sites across these factors, highlighting areas with a need for additional Cal/Val sites and a higher expected impact from their establishment. This index serves as a key tool within the framework to determine the optimal locations and number of new Cal/Val sites, as well as to evaluate the efficacy of utilizing existing ground observation networks. The framework was applied to South Korea, where the representativeness of the current eight Cal/Val sites was found to be insufficient. The optimal number of Cal/Val sites was determined to be 33, requiring the addition of 25 new sites in South Korea. The southeastern peninsula and surrounding islands were identified as priority regions for new installations. Additionally, the potential for utilizing the existing ground observation network was examined. Twenty-three Automatic Mountain Meteorology Observation System (AMOS) sites in South Korea were selected and compared with the optimized Cal/Val sites. The inclusion of these 23 AMOS sites was found to significantly improve representativeness, approaching the level of the optimized Cal/Val sites. This strategic deployment is expected to enhance the accuracy and reliability of remote sensing data, contributing to improved environmental monitoring and research in South Korea. Full article

Taking into consideration the moderating role of perceived organizational support within the framework of the natural resource-based view (RBV) theory, the purpose of this study is to investigate the connection between corporate social responsibility (CSR) and sustainable environmental performance. Specifically, this study focuses on the roles that green capability and green transformational leadership play as mediators in this relationship. Through the use of a survey questionnaire, information was collected from 420 employees working for small- and medium-sized enterprises (SMEs) in Bangladesh. The data were analyzed with the help of AMOS and SPSS. The findings indicate that the level of CSR has a significant impact on the performance of sustainable environmental practices. To a large extent, green capability and green transformational leadership serve as mediators in the relationship between CSR and sustainable environmental performance. Furthermore, perceived organizational support plays a significant role in moderating the relationship between CSR and sustainable environmental performance. The relationship between green transformational leadership and sustainable environmental performance is also significantly moderated by perceived organizational support. This is a significant contributor to the connection. This multidimensional corporate social responsibility model can be used to assess sustainable environmental performance in both industrialized and developing countries, and it can also be extended to other service sectors, according to the theoretical conclusion that can be drawn from the research. This research demonstrates that there is a direct connection between corporate social responsibility and sustainable environmental performance. As a result, practitioners are able to develop strategies that are effective in terms of corporate social responsibility. These findings should be taken into consideration by policymakers and managers who are dedicated to promoting equitable development of the country. Full article

This study presents a comprehensive analysis on the variations in the tropical cyclone (TC) frequencies during 1980–2021, including the linear trends, periodicities, and their variabilities on both global and basin-wise scales. An increasing trend in the annual number of global TCs is identified, with a significant rising trend in the numbers of tropical storms (maximum sustained wind 35 ktsUmax<64 kts) and intense typhoons (Umax96 kts) and a deceasing trend for weak typhoons (64 ktsUmax<96 kts). There is no statistically significant trend shown in the global Accumulated Cyclone Energy (ACE). On a regional scale, the Western North Pacific (WNP) and Eastern North Pacific (ENP) are the regions of the first- and second-largest numbers of TCs, respectively, while the increased TC activity in the North Atlantic (NA) contributes the most to the global increase in TCs. It is revealed in the wavelet transformation for periodicity analysis that the variations in the annual number of TCs with different intensities mostly show an inter-annual period of 3–7 years and an inter-decadal one of 10–13 years. The inter-annual and inter-decadal periods are consistent with those in the ENSO-related ocean drivers (via the Niño 3.4 index), Southern Oscillation Index (SOI), and Inter-decadal Pacific Oscillation (IPO) index. The inter-decadal variation in 10–13 years is also observed in the North Atlantic Oscillation (NAO) index. The Tropical North Atlantic (TNA) index and Atlantic Multi-decadal Oscillation (AMO) index, on the other hand, present the same inter-annual period of 7–10 years as that in the frequencies of all the named TCs in the NA. Further, the correlations between TC frequencies and ocean drivers are also quantified using the Pearson correlation coefficient. These findings contribute to an enhanced understanding of TC activity, thereby facilitating efforts to predict particular TC activity and mitigate the inflicted damage. Full article

This study assessed the mediating role of green competence in the relationship between digital orientation and green innovation performance among Chinese manufacturing firms. This study gathered data from 227 manufacturing firms located in the Jiangsu Province of China. Data were gathered using a structured questionnaire and analyzed using a covariance-based structural equation modeling in Amos (v.23). The findings revealed that digital orientation had a direct effect on manufacturing firms’ green innovation performance. This study also reveals that digital orientation had a direct positive effect on green competence. Also, green competence had a direct effect on green innovation performance. Finally, it was identified that green competence partially mediated the relationship between digital orientation and manufacturing firms’ green innovation performance. Full article

Tourists’ mental health risk perceptions have a crucial impact on destination management organizations and other tourism practitioners. As an important support for rural tourism, the mental health risk perception of rural homestay tourists requires further attention from researchers to promote the sustainable development of the rural homestay industry. Based on the structural equation model and AMOS, this study considers the rural homestay industry as the background, explores the relationship between the mental health risk perception of rural homestay tourists under the COVID-19 pandemic, emotional solidarity between tourists and operators, and tourists’ willingness to revisit, and analyzes the differences in tourist groups with different infection frequencies. In this study, questionnaires were randomly distributed to the tourists of rural hotels in Nanjing. 740 questionnaires were collected and 666 valid questionnaires were recovered. The results show that tourists’ mental health risk perception has a significant negative effect on tourists’ willingness to revisit. However, tourists’ mental health risk perception effectively promoted emotional solidarity between tourists and operators, and thus significantly improved tourists’ willingness to revisit, in which emotional unity was the mediating variable. There were significant differences in tourists’ willingness to visit after different infection frequencies. The willingness of tourists to risk being infected with the virus was more significantly affected by their mental health risk perception and emotional solidarity. Full article
