In the recent times, researchers have shown an increased interest in positive psychological capital (PsyCap). However, it is acknowledged that due to the limited number of studies conducted on the antecedents of psychological capital, there is a lack of sufficient data for conclusively proving the antecedents of PsyCap. Consequently, this article aims to explore the potential antecedents of PsyCap as a reliable source of data in the context of rural school teachers. The focus is to investigate both the individual differences and the contextual factors as desirable variables that constitute PsyCap among the school teachers of rural Jharkhand, India. Samples of 1,120 respondents from different rural schools were collected and analysed with Structural Equation Modeling (AMOS 20.0). The findings of the study explained that both the individual differences ( proactive personality and emotional intelligence) and the contextual factors ( perceived organizational support, servant leadership and meaningful work) have a positive relationship with PsyCap. The impact of PsyCap on teacher performance can form the basis for further research on the subject. JEL Codes: M12, M53

Abstract Background Eating disorders (ED) can reduce quality of life by limiting participation and performance in social and occupational roles, including paid or unpaid work. The association between ED pathologies and work participation and performance must be well understood to strengthen vocational rehabilitation programmes and prevent occupational disruptions in the ED population. The aims of this study are: (1) to examine the degree of association between ED pathologies and work participation and performance in 15-year-olds and older; (2) to highlight the specific ED symptoms that are most correlated with changes in work performance and participation; (3) to compile the most common metrics and assessments used to measure work participation and performance with ED. Methods Medline, Embase, CINAHL, Web of Science, PsycINFO, and Cochrane Library will be searched for observational and experimental studies that meet the following criteria: (1) a clinical sample of typical or atypical ED; (2) paid or unpaid employment or training; (3) an association between ED pathologies and work participation or performance. Unpublished data will also be examined. Title and abstract, and full-text screening will be conducted in duplicate. Risk of bias and quality of evidence assessments will be completed. A random-effect meta-analysis will be performed. Discussion This synthesis can clarify knowledge and gaps around the impact of ED on work functioning, thereby allowing better evaluation, improvements and development of current workplace assessments, interventions, and policies. Trial registration The registration number for this systematic review on PROSPERO is CRD42021255055.

Entrepreneurial passion is seen as a valuable predictor of entrepreneurs' behavior and performance. We explored what makes entrepreneurs passionate by adopting a qualitative research method from a social support perspective. To test our hypotheses we conducted a survey with 287 young entrepreneurs in China. Using structural equation modeling we studied the impact of three types of support from the family on entrepreneurial passion. The results show that financial support and social capital support had a stronger influence on entrepreneurial passion than did emotional support. Further, psychological capital played a partial mediating role in the relationship between family support and entrepreneurial passion. This study enhances the integrity of previous research conclusions on entrepreneurial passion and, in particular, provides further insight into the development of nascent entrepreneurs and their new businesses.

In an environment with ever changing customers’ needs and intensifying global competition, quality processes and supply chain (SC) are critical for organisational success. To satisfy customers, outsmart competition and improve performance, contemporary organisations are trying to improve on their processes through integrated supply chains. In an attempt to address this question and effectively contribute to this topic, a comparative meta- analytical evaluation along with key moderator and mediator analysis was conducted. In the lens of many theories, SCI from two perspectives; SCID (internal, suppliers, customer integration) with 67 studies and SCIF (information, operational, relational integration) with 25 studies was assessed on overall performance as well as on both operational and business performance. A quantitative meta-analysis based on Hunter and Schmidt (2004) which was performed through Jamovi, revealed the following: The meta-analysis results which were obtained through Jamovi provided significant correlation coefficients for SCID and SCIF respectively (ř = .476, p <.002) and (ř =.508, p <.001). Therefore, indicating that the association between SCID and performance is medium and positive, while that of SCIF and performance is positive and large. This is a clear indication that SCI from the perspective of SCID and SCIF yields different results, with SCIF having a relatively large effect. Moreover, on average SCIF both at aggregate and individual level has a slightly large effect on performance than SCID. Operational performance was the most influenced by SCID and SCIF, although operational and relational integration indicated a significant larger effect on business performance. Thus, individual SCID and SCIF constructs have different effects on business and operational as overall performance. All moderators though with different levels of interactions indicated a significant effect on both SCID and SCIF. Of the three mediators tested, customer integration had a 32% negative effect, SC agility showed an 89.1% full mediation effect with flexibility indicating a 53% significant effect.

Evidence synthesizing the effects of acute body water losses on various markers of glycemic regulation, appetite, metabolism, and stress is lacking. Thus, the purpose of this review was to summarize the response of various hormonal changes involved in these physiologic functions to dehydration. A comprehensive literature search for peer-reviewed research in the databases PubMed, Scopus, CINAHL, and SportDiscus was conducted. Studies were included if they contained samples of adults (>18 years) and experimentally induced dehydration as measured by acute body mass loss. Twenty-one articles were eligible for inclusion. Findings suggested cortisol is significantly elevated with hypohydration (standard mean difference [SMD] = 1.12, 95% CI [0.583, 1.67], p < 0.0001). Testosterone was significantly lower in studies where hypohydration was accompanied by caloric restriction (SMD= −1.04, 95% CI [−1.93, −0.14], p = 0.02), however, there were no changes in testosterone in studies examining hypohydration alone (SMD = −0.17, 95% CI [−0.51 0.16], p = 0.30). Insulin and ghrelin were unaffected by acute total body water losses. Acute hypohydration increases markers of catabolism but has a negligible effect on markers of glycemic regulation, appetite, anabolism and stress. Given the brevity of existing research, further research is needed to determine the impact of hydration on glucagon, leptin, peptide YY and the subsequent outcomes relevant to both health and performance.

PurposeWith the rise of service economy, many companies are attempting to gain a competitive advantage through service innovation. However, the existing research has not drawn consistent conclusions about the relationship between service innovation and firm performance. Hence, the purpose of this paper is to provide a quantitative review on the service innovation-performance relationship based on research findings reported in the extant literature.Design/methodology/approachStudies from 46 peer-reviewed articles were sampled and analyzed. A meta-analytic approach was adopted to conduct a quantitative review on the relationship between service innovation and firm performance, and the effects of any potential moderators were further explored.FindingsThe results found that service innovation has a significant positive impact on firm performance. Additionally, the relationship between service innovation and firm performance is influenced by measurement moderators (economic region and performance measurement), and contextual moderators (firm type, innovation type, customer factors and attitudes toward risk).Originality/valueThe meta-analysis has been used to explore the relationship between service innovation and firm performance, and the findings have contributed to the literature on service innovation, as well as providing future research directions.
