The Impact of Social Capital on Suicidal Ideation for the Elderly: Focusing on the Mediating Effect of Depression

Purpose The purpose of this paper is to propose an integrated theory to explain the effect of regional culture on high-technology micro and small (HTMS) firm outcomes. The integrated culture-social capital outcomes (CSCO) model examines the impact of culture on performance and evolution of HTMS firms through the mediating effect of intra-firm and inter-firm social capital. Design/methodology/approach Theoretical insights from social capital and culture are combined with the results of previous empirical observations to explain cross-cultural differences in the performance of HTMS firms. The authors then propose the CSCO model as a means to integrate and advance theory building. Findings The CSCO model explains the impact of culture on performance and evolution of HTMS firms through intra-firm and inter-firm social capital networks. Cultural context affects the performance of high-tech micro and small firms through the nature and structure of the networks involved in building and exploiting inter-firm and intra-firm social capital. Moreover, regional culture indirectly influences the balance between positive and negative effects of social capital on firm performance. These observations explain inconsistent findings from past empirical research and contribute to understanding the “embeddedness paradox” of social capital. Research limitations/implications The present model is not comprehensive. It does not account for many contextual factors identified in organizational network and cluster literature that contribute to the development of HTMS firms. Future research should consider the relationships between the three dimensions of social capital and seek to test the model with rigorous data collection and analysis. Originality/value While past studies focus on the direct relationship between regional culture and firm performance, this paper proposes the mediating effect of internal and external social capital between cultural context and firm performance. This proposal contributes to social capital and entrepreneurship literature and provides a potential explanation for inconsistent findings in past empirical research.

Objectives: Global aging is an increasingly serious problem. The health problems faced by the elderly, such as depression and obesity, require serious consideration. Education, depression and obesity are inextricably linked; for the elderly, education is constant, and the factors which can mediate the relationship between education, depression and obesity are still being discussed by scholars. The mediating effect of social capital is rarely studied. The objective of this study was to assess the mediating role of cognitive social capital and structural social capital, as well as the effect of education on depression and obesity among the elderly using China Family Panel Studies (CFPS) data. Methods: In total, 4919 respondents were included in the final analysis. Education was measured by years of schooling. Trust and participation were used as measures of cognitive social capital and structural social capital. Depression symptoms and BMI were used as outcomes. Structural equation models were developed to examine the direct and indirect effect of social capital and education on health outcomes. Results: Education was negatively correlated with depression symptom (r = −0.15, p < 0.001), while education was positively correlated with BMI (r = 0.08, p < 0.001). Older adults with a higher education level have higher cognitive social capital (r = 0.11, p < 0.001) and structural social capital (r = 0.20, p < 0.001). Social capital plays a mediatory role. Older adults with higher social capital have a lower risk of depression (cognitive: r = −0.23, p < 0.001; structural: r = −0.03, p < 0.01) but a higher risk of obesity (cognitive: r = 0.06, p < 0.01; structural: r = 0.03, p < 0.01). For depression, the mediating function of cognitive social capital (a1b1= −0.025) is stronger than that of structural social capital (a2b2 = −0.006). While, for obesity, the effects of both cognitive and structural social capital are the same (a1c1 = a2c2 = 0.005). Conclusions: Social capital as a mediator through the effect of education on depression and obesity among the elderly in China. Meanwhile, using the positive effects of social capital to avoid negative effects should also be seriously considered.

The Impact

In knowledge economy era, enterprise needs to innovate to maintain its advantages and competitiveness. Construction enterprises, being pillars of China’s economy and confronting the challenge brought by the strategy of “going out”, the call for their technology or management innovation was broadly pronounced across practical and academic fields. Social capital (SC), as a resource in a social network, is the basis for creating sustainable competitiveness and advantage for enterprises. The innovative achievements and innovation performance (IP) of enterprises are largely determined by their SC. To achieve competitiveness in the market, enterprises must carry out knowledge transfer (KT) with the other members of their networks. However, few scholars have examined weather SC has any effect on IP in construction enterprises. Using a KT perspective, this paper explored how SC affects the IP of construction enterprises. Based on the literature review and analysis, a conceptual model was constructed and validated using structural equation modeling (SEM). Through empirical analysis, the following conclusions were drawn: (1) SC has a positive impact on the IP of construction enterprises. Among them, the structural dimension (SD) and cognitive dimension (CD) have a significant positive impact on the IP of construction enterprises, while the relational dimension (RD) does not. (2) The SD, CD, and RD of construction enterprises’ SC have a positive influence on KT. (3) There are mediating effects of KT between SC and IP of construction firms, and they are partial. KT plays a partial mediating effect between SD, CD, and IP of construction firms. The research results can not only improve an understanding of effects of SC on IP of construction enterprises, but also validate the importance of KT in stimulating IP.
