The COVID-19 pandemic has caused significant mortality and morbidity worldwide. However, the role of dietary patterns as a potential risk factor for COVID-19 has not been well established, especially in studies with large samples. Therefore, this study aims to identify and evaluate the association between major dietary patterns and COVID-19 among adults from Iran.

In this cross-sectional study, the authors included 9,189 participants aged 20–70 who participated in the Yazd Health Study (YaHS) and Taghzieh Mardom-e-Yazd study (TAMIZ). They used factor analysis to extract dietary patterns based on a food frequency questionnaire (FFQ). Then, they assessed the relationship between these dietary patterns and the odds of COVID-19.

This study identified two major dietary patterns: “high protein and high fiber” and “transitional”. Participants in the highest tertile of the “high protein and high fiber” dietary pattern, which included vegetables, fruits, dairy and various kinds of meats such as red meat, fish and poultry, had a lower odds of COVID-19 compared with those in the lowest tertile. However, the “transitional” dietary pattern did not affect the risk of COVID-19.

In conclusion, a “high protein, high fiber” diet may lower the odds of COVID-19. This study suggests that dietary patterns may influence the severity and spread of future similar pandemics.

This study examines the role of social media adoption (SMA), opportunity recognition (OR) and opportunity exploitation (OE) in mediating the relationship between entrepreneurial orientation (EO) and the performance of newly established small and medium-sized enterprises (SMEs) in emerging economies, with a particular emphasis on Ghana.

This study adopts a post-positivist philosophical stance and uses a quantitative approach and a survey design. A purposive sampling technique was used to select 336 SME owners and managers from Ghana’s manufacturing, trading and service sectors. Questionnaires were administered to source the empirical data for this study. Structural equation modelling (SEM) was used to analyse the proposed hypotheses.

The results reveal that EO positively and significantly influences the performance of new-born SMEs. SMA, OR and OE partially mediated this relationship.

This study is a wakeup call to policymakers, practitioners, managers and owners of recently established businesses. Policymakers should provide support and resources for newly established SMEs to adopt effective social media marketing strategies, bolstering their online presence and customer engagement. Simultaneously, they should invest in entrepreneurship education and create an environment conducive to innovation to cultivate an entrepreneurial mindset among fresh SMEs. Business owners and managers should proactively monitor market trends and consumer preferences, adapting their strategies to identifying and seizing emerging opportunities.

This study introduces a significant novelty to previous literature and one of the first to employ the dynamic capability theory to examine the interplay between EO, SMA, OR and OE in influencing the performance of new SMEs in the context of emerging markets. Furthermore, it extends the scope of understanding of the mechanisms through which SMEs can prosper in these dynamic environments. This unique combination of theoretical framework, comprehensive variables and contextual focus sets this study apart from existing research, enriching the literature on SME performance in emerging markets.

Initial Public Offering (IPO) is a major milestone for a company. It allows a private company to issue shares to a much broader group of investors and become public. But conclusive evidence of the driving forces behind investors’ demand is yet to be identified. Therefore, the major purpose of this study is to assess the level of investors’ demand in IPO and how investors’ demand in IPOs is affected.

The study will employ 80 IPO companies of a Muslim-majority country, Bangladesh, starting from 2013 to 2021 with application of linear and quantile regressions. Apart from that, t-test will be used to compare means of groups of Shariah-compliant and non-Shariah-compliant firms and IPOs under fixed-price and book-building mechanism.

Oversubscription is higher for IPOs issued through fixed-price method compared to book-building method, but no significant difference is found in oversubscription for Shariah firms compared to non-Shariah firms based on t-tests. The authors found IPO size, firm size, IPO risk, proportion of shares offered to public, and bank interest rate to have significant impact on the IPO demand. Some models found non-Shariah compliance status of IPO companies to be a significant factor for the investors to demand IPO. Quantile regression results found board independence to have a positive association with larger, less-subscribed firms and board size to have a negative relation with IPO demand, for smaller firms with high demand.

Future studies may apply the findings to other settings, especially into the reasons behind preference for non-Shariah-compliant firms and higher demand for IPOs during higher interest rate. Equity issuing firms and issue managers can benefit from this study by wisely deciding on the proportion of shares for public, issue size and board of director composition. Shariah considerations cannot be ignored given that more information on Shariah compliance is disseminated among investors despite current non-preference for Shariah-compliant IPOs. On the other hand, institutional investors and general investors should consider firm-specific, governance and macroeconomic factors in IPO investment. Likewise, regulators would do well to bring in quality IPOs with characteristics mentioned in this study for ensuring stability of the market.

The main contribution of the study is identifying determinants of IPO demand: faith, governance, macro issues – understanding whether one or many of the above factors drive investor demand in IPOs of a Muslim-majority country will be the main contribution.

The study aims to investigate the influence of corporate governance practices on enhancing firm value in manufacturing industries in Bangladesh.

The study sample consists of 131 companies from 10 manufacturing industries listed in Dhaka stock exchange (DSE). Using the multiple regression method, the study analyzed 1,193 firm-year observations from 2012 to 2021.

The outcome reveals that managerial ownership, foreign ownership, ownership concentration, board size, board independence, board diligence and auditor quality have a significant positive influence on firm value. In contrast, audit committee size has no significant influence on firm value.

The practical implications of the current study demonstrated that good corporate governance creates value and must be invigorated for the interest of all stakeholders. Policymakers should formulate specific guidelines regarding firms' ownership structure and audit quality issues.

Training activities organized by maker-spaces have become the most important channel through which makers acquire new external knowledge related to problem solving and thus contribute significantly to makers' innovation performance. Is it true that the more training activities in which makers participate, the better their innovation performance? Following the logic of process analyses, this paper empirically verifies the effects of the scope and frequency of makers' participation in training activities on their innovation performance.

Based on a survey of 134 makers in China, this paper employed the procedure recommended by Preacher and Hayes (2008) to empirically test the total effects, direct effects and indirect effects of the scope and frequency of participation in training activities on makers' innovation performance via their ability to exploit new knowledge.

The research findings show that the scope (frequency) of participation in training activities has a positive (negative) effect on makers' innovation performance via the mediating effect of the makers' ability to exploit new knowledge. Time pressure acts as a negative moderator.

This paper sheds light on a considerably overlooked research area by investigating the effects of the scope and frequency of makers' participation in training activities on their innovation performance. The authors further identify and empirically test the theoretical mechanism by considering the mediating effect of makers' ability to exploit new knowledge. The research findings also provide a managerial training activity arrangement strategy for makerspaces and government.

The board structure (BS) is pivotal in modern corporate governance (CG). This study aims to investigate BS variables (BSIZE, BIND and chief executive officer [CEO] duality) and their correlation with risk-taking behavior indicators, enriching the understanding of how CG shapes financial institutions’ (FIs) decision-making in Pakistan.

By scrutinizing data from 67 financial entities listed on the Stock Exchange of Pakistan spanning from 2011 to 2022 through panel data regression techniques, the research emphasizes that BS holds a substantial influence over the risk tendencies exhibited by these firms.

Key findings suggest that board size has a positive influence, aligned with previous CG research. Smaller boards perform better and avoid excessive risk-taking, contrasting some negative relationship claims. More independent directors are recommended to curtail risk and financial disruption. Holding both CEO and chair roles reduces risk exposure, resonating with reputational and employment risk theory. It is essential to recognize that BS’s impact on risk-taking is nuanced and context-dependent.

Policymakers, scholars, practitioners and investors working in the market for financial companies might greatly benefit from the empirical findings of this study. Imposing mandates on FIs to uphold adequate capital reserves functions as a safeguard against unforeseen losses, thereby diminishing the probability of unwarranted risk-taking.

Prior studies in this domain predominantly focus on nonfinancial sectors. In addition, existing research often explores the relationship between BS and firm risk-taking solely within the banking sector, overlooking other FIs. This study contributes by using a comprehensive data set encompassing all types of FIs, thus extending the existing literature.

This study aims to determine the influence of Mobile learning (M-learning) technologies based on the gender orientation of vocational education construction trade trainees in Pakistan.

Further, the data was collected using an adapted survey tool with a five-point Likert scale. Similarly, the data were analyzed through SPSS 27 software tool by using descriptive and inferential statistics.

The study's findings highlighted a positive influence of M-learning technologies based on the gender orientation of construction trade trainees from vocational institutions. Similarly, it is also specified that the challenges vocational trainees of the construction trade have faced while utilizing M-learning technologies were related. Hence, it is evident that the potential challenges of M-learning technologies integration and utilization are related to both gender orientations during a postpandemic situation in Pakistan.

In the Pakistani context, the M-learning technologies approach is recently introduced in the vocational education sector. Therefore, the utilization and integration of M-learning technologies are considered challenging tasks in the context. In this regard, this study helps to understand the acceptance, challenges and impact of M-learning technologies based on gender orientation among vocational institutions trainees of construction trade in Pakistan.

This study not only refers to the impact of M-learning technologies and their challenges but also highlights the current situation of M-learning in Pakistan, particularly construction engineering trainees in vocational education institutes.

We investigate the effect of the adoption of formal board structure and board processes on firm performance in Colombian family firms, in a context where firms can choose specific aspects of board structure and processes. We deploy insights from the behavioral governance perspective to develop arguments about how family businesses may choose board elements based on their degree of control over the firm (absolute control or less), and its effect on firm performance.

We use an unbalanced data panel of 404 firm-year observations. The data was obtained from the annual financial and corporate governance reports of 62 Colombian stock-issuing firms for the period 2008–2014 – due to change in regulation, data could not be added beyond 2014. Panel data technique with random effects was used.

The results show that board structure is positively associated with financial performance, however, this relationship is negative in businesses where family has absolute control. We also found that there is a negative association between board processes and performance, but positive association in family-controlled businesses.

Our research contributes to research streams on effects of family control in firm choices and on the interactive effect of governance choices and institutional context and more generally how actors interact (rather than react) with their institutional context.
