To obtain optimal deliverables, more and more crowdsourcing platforms allow contest teams to submit tentative solutions and update scores/rankings on public leaderboards. Such feedback-seeking behavior for progress benchmarking pertains to the team representation activity of boundary spanning. The literature on virtual team performance primarily focuses on team characteristics, among which network closure is generally considered a positive factor. This study further examines how boundary spanning helps mitigate the negative impact of network closure.

This study collected data of 9,793 teams in 246 contests from Kaggle.com. Negative binomial regression modeling and linear regression modeling are employed to investigate the relationships among network closure, boundary spanning and team performance in crowdsourcing contests.

Whereas network closure turns out to be a negative asset for virtual teams to seek platform feedback, boundary spanning mitigates its impact on team performance. On top of such a partial mediation, boundary spanning experience and previous contest performance serve as potential moderators.

The findings offer helpful implications for researchers and practitioners on how to break network closure and encourage boundary spanning with the establishment of facilitating structures in crowdsourcing contests.

The study advances the understanding of theoretical relationships among network closure, boundary spanning and team performance in crowdsourcing contests.

This study aims to conduct a systematic literature review to investigate the mental health problems during COVID-19 and the role of nutrition in minimizing mental and health-related issues during COVID-19.

A literature search was done electronically on April–May 2022 in the databases Google Scholar, PubMed and Cochrane Library, reviewing all the articles published in English. There were no limitations for the study (such as study design, region or any time frame). The quality assessment was done. The beginning database search picked out a total of 654 articles, 47 in PubMed, 575 in Google Scholar, 22 in Cochrane Library and 10 records from other sources. A total of 565 (duplicates found 89) were found after removing the duplicated articles, after reading the title and abstracts were further decreased to 88 full-text articles. These 88 studies went for full-text analysis, which excluded 56 studies and generated a final 32 articles for systemic analysis. The quality of the included study for the systematic review was assessed in two ways: one is evidence-based and another one on the JBI checklist.

People in social isolation and home quarantine suffer from severe anxiety, stress, depression, loneliness, anger and panic attack. During COVID-19, the vital role of diet and nutrients in mental health has been acknowledged and helps mitigate COVID-19 infection. Many studies showed stress and anxiety due to increased unhealthy eating and lifestyle practices.

This review will explain the interlink between diet and mental health because what we eat and think is interconnected with the gut–brain axis. The dietary elements and psychobiotic help in improving the immune system and psychological distress during the pandemic. This paper describes the role of different nutrients, psychobiotics and phytochemicals, to minimize mental and health issues during the COVID-19 pandemic. This paper also contains a balanced diet plan to withstand COVID-19.

Team social capital (TSC) has been attracting increasing research attention aiming to explore team effectiveness through within- and cross-team resource conduits. This study bridges two disconnected theories – TSC and evolutionary theory – to examine gaming clans and analyzes mechanisms of the clans' TSC building from an evolutionary perspective.

This research draws longitudinal data from a sample of gaming teams (N = 1,267) from anonymized player data from the game World of Tanks spanning 32 months. The authors explored teams' evolutionary patterns using hidden Markov models and applied longitudinal multilevel modeling to test hypotheses.

The results showed that teams of different sizes and levels of evolutionary fitness vary in team closure and bridging social capital. The authors also found that larger teams are more effective than smaller ones. The positive association between team-bridging social capital and effectiveness is more substantial for smaller teams.

This research advances the theoretical development of TSC by including the constructs of teams' evolutionary status when analyzing strategic social capital building. Adding to existing literature studying the outcome of TSC, this research also found a moderating effect of team size between TSC and effectiveness. Finally, this study also contributes to a longitudinal view of TSC and found significant evolutionary patterns of teams' membership, TSC, and effectiveness.

This study aimed to investigate the impact of a university’s abrupt closure on the lives of graduate students and examined the role of grit, social support and school identification as they transferred to a new institution.

An online survey was administered to a diverse sample of 130 psychology graduate students after their university unexpectedly closed and the students transferred to another institution to complete their degrees. The survey included both qualitative and quantitative measures of the impact on different areas of their lives, anxiety and depression, life satisfaction, social support, grit and school identification.

Students reported experiencing financial loss, family and marital strain, anger, fear, uncertainty and loss of progress toward professional goals. Nearly 40% of participants had scores indicating elevated anxiety and depression. Students with higher anxiety and depression and lower life satisfaction tended to identify less with their new institution. Both social support and grit were related to better adjustment and life satisfaction.

To the best of the authors’ knowledge, this is the first study to examine the impact on graduate students following the closure of an institution of higher education. The findings have implications for educational policy and graduate student support services.

Ageism has deleteriously influenced individuals and society for nearly half a century. Despite receiving increased attention, it remains under-researched regarding how it might be reduced in the workplace. Even though its prevalence and allure, review studies on workplace ageism (WA) are also scarce, and thus a review is warranted.

To fill the preceding void, this study will systematically review the existing literature on WA using data from the past four decades.

This study identified the various antecedents and the intervention mechanism through which WA may be reduced. Additionally, through reviews, the authors advance the research by offering promising avenues for future research.

This review contributes to human resources managers and will inspire future scholars to delve deeper into combating age discrimination, stereotypes and bias toward employees in workplaces.

Taking a resource-based view, the authors analyse the effect of high-performance work practices (HPWPs) on the performance of small- and medium-sized enterprises (SMEs) under conditions of environmental hostility, and consider how this relationship is influenced by managers' embeddedness in social networks. The authors argue that high perceived levels of environmental hostility strengthen the strategic value of HPWPs in SMEs, whereas high levels of manager embeddedness in social networks weaken this contingent relationship.

These hypotheses were tested in a sample of 249 SMEs, from two Spanish industries related to food production, using linear regression with two- and three-way interaction effects.

The study results show that the implementation of HPWPs benefits SMEs' performance in hostile environments. However, the dark side of managers' social capital could undermine any such benefit, especially if there is a high degree of network closure. In hostile contexts, such closure appears to limit managers' willingness to depart from the common practice of reducing investment in human resources.

Contrary to predominant beliefs that managers facing economic adversity should reduce costs by cutting investment in personnel development, this study indicates that supporting HPWPs enhances a firm's objective financial performance.

This study advances our understanding of the specific conditions under which HPWPs sustain SME performance. It also introduces the dark side of managers' social capital into considerations of this relationship. The study findings provide new insights that are counterintuitive to business practice.

The present study aims to investigate the reasons for the gap between academic education and the required skills of the labor market in Iran.

For this purpose, the authors adopted a thematic analysis method. The participants in the study were connoisseurs from universities and research institutes in Iran, who were selected with purposeful sampling methods of snowball type. To collect the data, the authors used a semi-structured interview and performed a thematic analysis for data analysis.

The findings showed that the views and perceptions of the connoisseurs participating in the study about the reasons for the gap between academic education and the skills required in the labor market in Iran can be classified into four main themes including lack of attention to labor market needs in the academic curricula, lack of attention to practical and entrepreneurial skills in the academic curricula, the weak link between universities and industry and society, and shortage of academic resources and equipment in some academic disciplines.

The present study had three implications. First, the human capital theory, the social closure theory, the positional conflict theory and the labor market segmentation theory are more compatible with the labor market of Iranian graduates, compared to other theories of the labor market. Second, the lack of coordination between academic education and the required skills in the labor market has weakened the Iranian economy. Third, the absence of practical and entrepreneurial skills in academic graduates has led to increased unemployment in Iranian society.

This study aims to analyze the connection between institutional isomorphic pressures and both women serving on boards and women’s influence on boards within large American firms.

This study examines a longitudinal panel data set of all Standard and Poor’s (S&P) 500 organizations across a seven-year period from 2009 to 2015.

The analyses affirm that institutional isomorphic pressures impact the prevalence and influence of women on boards. Evidence suggests that coercive and normative pressures strongly impact the number of women serving as corporate directors, whereas the power of women directors is linked only to mimetic pressures.

The research suggests that to increase the number of women serving as directors, the industry must first increase the overall number of women serving in senior management roles. Once women directors gain a critical mass of three women on the board, the association with the total number of women directors, the number of boards upon which they concurrently serve, the power of women directors being selected to board leadership and the influence of women directors increase.

This paper extends existing board diversity work by examining institutional pressures at the international, national and firm levels. By examining the relationship between coercive, normative and mimetic pressures on both the prevalence of women on boards and the influence of women on boards, the authors illuminate certain mechanisms that shape the likelihood of board appointment and placement in more powerful positions.

The COVID-19 pandemic was particularly challenging for developing countries because of pre-existing poverty and severe inequality. Governments tended to set public safety as a primary goal, but it could not be their singular goal. Broadband was an important feature of any policy solution. Business lockdowns, school closures, and social distancing led to an unprecedented acceleration in the demand for broadband. But the government restrictions on social and economic interactions made it difficult to maintain and expand broadband networks. Governments might have let markets work out this challenge of escalating demand and increasing costs of supply, but few did. Governments quickly grew to believe that it would need cooperative relationships among multiple government agencies and private businesses to answer what appeared to be a broadband shortage. Regulatory controls over broadband providers were quickly suspended in favour of developing common goals and coordinated efforts. These approaches proved effective, although citizens continued to suffer from the pandemic.

The purpose of this chapter is to examine the budgeting process in a local church from a social capital perspective. The social capital provides novel insights into the construction of budgets and its social aspects. A qualitative case study was adopted, with an interpretive methodology. Semi-structured interviews were used to interview 14 managers involved in the budgeting process at a local independent church. The interview data were supplemented by documentary evidence. Nahapiet and Ghoshal (1998) framework of social capital was used to analyse the data. The main finding was that budgeting was found to be a social process – that can best be explained by social capital theory. There may be an element of self-selection, as the church agreed to participate in the study and chose to allow a researcher to examine social aspects of its budgeting process. The chapter contributes to both social capital theory and church literature. Social capital provides novel insights into the construction of budgets and its social aspects. In addition, contemporary budgeting practices are studied in a church in a denomination and country not previously studied.
