The purpose of this systematic review and meta-analysis was to investigate the efficacy of propolis on glycemic indices in type 2 diabetic patients.

Web of science (ISI), Embase, Scopus and PubMed were systematically searched to find randomized controlled trials (RCTs) assessing the effects of propolis intake on glycemic controls in type 2 diabetic patients, from inception up to September 1, 2020. A random-effects model was used to pool weighted mean difference (WMD). Meta-regression was performed to detect the potential sources of inter-study heterogeneity.

Seven trials were included in the meta-analysis. Compared to controls, propolis intake significantly improved serum fasting blood sugar (FBS) (WMD = −13.62 mg/dl, 95% CI = [−23.04, −4.20], P = 0.005, I2 = 58.5%) and hemoglobin A1C (HbA1c) (WMD = −0.52%, 95% CI = [−0.86, −0.18], P = 0.002, I2 = 64.0%). In contrast, receiving propolis did not change serum insulin (WMD = −1.46 (uIU/ml), 95% CI = [−2.94, 0.02], P = 0.05, I2 = 75.0%) and homeostatic model assessment for insulin resistance (HOMA-IR) (WMD = −0.98 (%), 95% CI = [−2.00, 0.04], P = 0.06, I2 = 82.3%) compared to controls.

The present meta-analysis demonstrated that propolis intake significantly reduces serum FBS and HbA1c in diabetic patients but does not alter serum insulin and HOMA-IR. Further large-scale RCT’s are needed to approve these effects.

Previous research indicates that vitamin D and omega-3 co-supplementation may benefit overall health, but current evidence regarding its effects on lipid profile remains unclear. The present systematic review and meta-analysis aimed to examine the effects of vitamin D and omega-3 co-supplementation on lipid profile (total cholesterol [TC], low-density lipoprotein [LDL], triglyceride [TG] and high-density lipoprotein [HDL]) in adults.

In this systematic review and meta-analysis, relevant studies were obtained by searching the PubMed, Scopus and Web of Science databases (from inception to January 2022). Weighted mean differences and 95% confidence intervals were estimated via a random-effects model. Heterogeneity, sensitivity analysis and publication bias were reported using standard methods.

Pooled analysis of six randomized controlled trials (RCTs) revealed that vitamin D and omega-3 co-supplementation yielded significant reductions in TG (p = 0.631). A pooled analysis of five trials indicated a significant association between omega-3 and vitamin D treatment and reductions in TC (p = 0.001) and LDL (p = 0.001). Although, pooled analyses of omega-3 and vitamin D did not significantly affect HDL.

The findings suggest that vitamin D and omega-3 co-supplementation lowers TG, TC and LDL in adults. Future, large-scale, RCTs on various populations are needed to elucidate further beneficial effects of vitamin D and omega-3 co-supplementation on lipid profile and establish guidelines for clinical practice.

Although the issues related to the motivation of entrepreneurs have been widely studied, there is a less study focussing on the immigrant women’s entrepreneurial motivation under challenging environment such as COVID-19. Existing studies on entrepreneurs’ motivations mainly adapt the concepts that have often been developed in male-dominated paradigm. According to Shmailan (2016), male entrepreneurs focus on making sure costs are under control and are more profit driven. Women seek to make social contributions and want to ensure their quality. Some of the literature suggests that men are inclined to start businesses because of financial considerations and are more likely to be pulled into entrepreneurship. Conversely, women are likely to start business because of lifestyle issues and are more likely to be pushed into self-employment (Clain, 2000; Georgellis & Wall, 2005; Takahashi, Lourenço, Sander, & Souza, 2014).

This chapter focuses on the motivation of immigrant females in developed economies and what makes them continue especially during difficult times such as recent crisis ‘new normal’, COVID-19 pandemic. The study explores the challenges ethnic female entrepreneurs are facing and what motivated them to continue. The study also seeks their responds and strategies during challenging time such as the pandemic. The findings indicate that women often pursuit business opportunities to satisfy social needs, rather than focussing on traditional business outcomes such as growth or profit. The study found a stronger desire to contribute to a society, community and family’s needs among female founders in the UK . The immigrant female entrepreneurs have shown strong resilience during the COVID-19 pandemic crisis.

This paper aims to develop a conceptual taxonomy for building requisite knowledge capabilities for different supply chain network (SCN) types. Specifically, it examines knowledge capabilities required for three types of SCNs: efficient, collaborative and agile SCNs.

This paper integrates two bodies of thought (i.e. knowledge management and organisational learning) and applies them to SCNs. An abductive research process is used to develop this conceptual taxonomy.

The conceptual taxonomy details three archetypical knowledge capabilities – exploitation, exploration and ambidextrous. Those knowledge capabilities are required for efficient, collaborative and agile SCNs, respectively.

This paper is conceptual and theory-based. The next stages of the research seek to further strengthen the explanatory value of the taxonomy through empirical validation.

The taxonomy developed in this paper provides a valuable and pragmatic tool for managerial decision-making in the context of SCNs. Specifically, it provides a roadmap for practitioners since the study develops an understanding of the relationship between knowledge capabilities and types of SCNs.

This is one of the earliest studies that attempt to unearth requisite knowledge capabilities for different types of SCNs.

The consequences of a media-shaped perceptual destination attribute during the pandemic on a commitment to embrace and thread trip intent are explored in this research. The influence of four elements related to the choice of destination, involving reliability, strategic planning, health service, and friendly relationship on tourism performance expectancy are chosen depending on visitors' previous experience of a certain place, using the notion of psychological tourist satisfaction and an interactive personality questionnaire. Industry 4.0 paradigms are either viewed with skepticism or eagerness by organizations. Organizations that develop different innovative strategies to leverage the digital world doing and offering greater opportunity will certainly drive the evolution in tourism. Any revolutionary technology has the potential to benefit or harm enterprises. An Industry “4.0” data type depicts the technological transformation occurring inside a given business, from Industrial Revolution 4.0 to dealing with customers 4.0. However, one instance is Tourism 4.0. Social networking is not unique. Hospitality organizations, especially, must be acutely conscious of the customer's power as a result of social networking sites. The increase in security concerns by preventing the rate of cybercrime and by enhancing the secure money transactions in online reputation management consolidates the socioeconomic relationship. The comparative study has been propagated in relevance to the pre- and post-pandemic effects on the tourism industry.

The present study aims to identify and evaluate the socioeconomic barriers to effective COVID-19 pandemic transmission control in Pakistan.

The study identifies multiple socio-economic barriers through an extensive literature review. The preliminary analysis unveiled 15 socio-economic barriers. Nine experts were contacted to collect data and finalize the most prominent barriers to COVID-19 transmission control using the DELPHI method. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to process and interpret the data collected and a cause–effect relationship was established among the barriers.

The finalized barriers to effective COVID-19 pandemic transmission control were evaluated using DEMATEL which grouped criteria into two grouped criteria – cause and effect. The DEMATEL analysis shows that poor safety culture, lack of strategy and goal setting, lack of resources, late realization and recognition of the pandemic problem and lack of expertise and capacity in disaster and risk management fall into the cause group. These factors are critical as they directly affect the remaining barriers identified in the study.

Despite the collective global efforts, the national economies have been struggling to completely control COVID-19 transmission control. Pakistan’s economy has been facing the third wave of the pandemic. It is mandatory to identify the barriers and evaluate them to develop a comprehensive strategy ensuring that there would be no fourth wave. The study identifies and evaluates the barriers to COVID-19 transmission control in Pakistan using the integrated DELPHI-DEMATEL framework. The findings would help the government, experts and strategists to develop a comprehensive disaster and risk management strategy.

The purpose of this paper is to develop a commercialization model based on gaining economic benefits through the transfer of technological capabilities in the oil and gas industry. Since commercialization models are mostly based on the implement of technology to produce and sell new products, this study focuses on developing a specific independent technology commercialization model.

The method of this research is qualitative based on the grounded theory. For this purpose, general variables with content analysis were extracted by reviewing documents (Literature review) and then for identifying special components, interviewing experts in the Iranian oil and gas industry. Participations were selected using snowball sampling for semistructured interviews.

The findings of this research were extracted based on grounded theory with data analysis in MAXQDA software. In this research, first, 210 open codes were identified based on qualitative content analysis of relevant documents and results of interviews with experts. Then the classification of open codes was done, and 46 subcategories (variables) were determined in the commercialization model. Finally, 46 subcategories were classified into 10 categories as axial codes in grounded theory as components of the commercialization model.

The results of this research have led to the creation of new practical and theoretical implications. In this research, a new perspective of commercialization with the aim of transferring technology and obtaining its economic benefits for oil and gas industry companies was discussed. Also, based on the practical implications explained in this research, policymakers can use the suggested model to effectively implement independent technology commercialization to acquire economic benefits.

This study is purely original and the outcome of the research conducted by the authors. The research findings are the outcome of in-depth study on technology commercialization in the Iranian oil and gas industry.

Understanding consumers’ food safety practices are helpful in reducing foodborne illnesses. The purpose of this study is to evaluate the influence of education on knowledge, attitude and practices toward food additives.

This interventional study was performed by random sampling of 826 employees in Isfahan University of Medical Sciences from January 2018 to March 2019. The knowledge, attitude and practices of the employees toward food additives were assessed by a self-administered and structured questionnaire. Two-month education was conducted visually by using pamphlets, posters and leaflets. Descriptive statistics and paired t-test were done by SPSS24 at significant levels of p < 0.05.

The results showed that the respondents were very concerned about preservatives, colorants, and artificial sweeteners in foods. Before the education, the percentages collected for the knowledge, attitude and practice were 79.0, 48.9 and 46.7, respectively. Overall, knowledge scores were improved from 79.0 to 88.9 per cent when the education was offered. Safety attitude scores significantly increased, with a 50 per cent difference between the pre and post values. A significant difference was observed in the percentage of knowledge, attitude and practice of the employers before and after education (p < 0.05). Almost half of the respondents chose leaflets and pamphlets as a preferable tool for learning.

Education may be needed for improving knowledge and attitude about food additives. It also helped the respondents to select healthier food. This study suggests more communication programs regarding food safety issues.

Coronavirus Disease 2019 (COVID-19) pandemic has affected many different aspects of people’s lives around the world, including household food security. This study aims to investigate the food security status and its determinants, with emphasis on perceived social support among the Iranian population during the epidemic..

This cross-sectional study was conducted among 2,871 Iranian adults by social media in all provinces of the country. Demographic and socioeconomic information, household food security status and perceived social support status were assessed by the validated questionnaires. Data was analyzed by statistical package for the social sciences version 22.0, with one-way ANOVA, Chi-square and multinomial logistic regression tests.

The prevalence of food security among the studied population was 55.2%. The results indicated that perceived social support plays a protective role on food security [odds ratio (OR) = 1.07, confidence interval (CI) = 1.06, 1.09, P-value < 0.001]. Reduced income during the epidemic [OR = 0.29, CI = 0.17, 0.47, P-value < 0.001] and presence of an old person (>65 years old) in the household [OR = 1.72, CI = 1.14, 2.60, P-value < 0.05], were significantly higher among moderate to severe food insecure group than food-secure group. More monthly income [OR = 0.28, CI = 0.13, 0.57, P-value < 0.001] and homeownership [OR = 1.83, CI = 1.22, 2.75, P-value < 0.05] were also predictors of food security status.

The development of supportive strategies which act immediately can protect vulnerable people against the consequences of the epidemic, including food insecurity. Long-term planning should also be considered to improve society’s resistance against such disasters.
