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.

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.

This study aims, a systematic review and meta-analysis, to evaluate the effects of folic acid (folate) on patients with depression.

Related articles were found by searching PubMed, SCOPUS, Web of science and Cochrane’s Library, from inception to January 2022. Weighted mean differences (WMD) were pooled using a random-effects model. Heterogeneity, sensitivity analysis and publication bias were reported using standard methods.

Pooled analysis of six randomized controlled trials revealed that folic acid supplementation decreased the depression score in the Beck Depression Inventory (WMD: −3.9; 95% CI: −5.3 to −2.4, p < 0.001) compared with control group, without heterogeneity (I2 = 0.0%, p = 1.000). It also lowered the depression score in the Hamilton (HAM) Depression Inventory (WMD: −3.5 mg/dL; 95% CI: −4.6 to −2.4, p < 0.001) compared with control group, with moderate heterogeneity (I2 = 71.8%, p = 0.007). Moreover, subgroup analysis showed that the folic acid supplementation reduced HAM in all subgroups. Meta-regression analysis demonstrated that there is no evidence of a significant linear relationship between dose and duration of folic acid supplementation and changes in HAM. Also, based on the non-linear dose response, no evidence of a relationship between dose and duration of folic acid supplementation and changes in HAM was found.

Folic acid supplementation could possibly have an effect on lowering depression in patients. However, the clinical trials thus far are insufficient for clinical guidelines and practice.

The purpose of this paper is twofold: first, to provide a descriptive analysis of consumers’ ability to comprehend and use common price promotion information when they choose to do so (e.g. to find the least expensive price or to understand the savings amount); second, to identify which consumer groups (in terms of demographic characteristics) find price promotion comprehension particularly challenging.

An online questionnaire with 14 measures (four literacy, ten numeracy) was administered in the study. Data from 607 Australian consumers were analysed using descriptive, cross-tabulation, and multiple regression analysis via IBM SPSS analytics software.

On average, 20 per cent of the consumers surveyed were unable to comprehend the price promotion signage. On average, 13 per cent of the consumers were unable to carry out arithmetic tasks using the information on price promotion signage. Multiple regression models showed that income level was the main driving factor for the consumers’ price promotion literacy and numeracy levels.

The present study is the first exploratory examination of consumers’ levels of comprehension (literacy) and effective use (numeracy) regarding common types of price promotion communication. The use of online samples and data collection method overestimates the results effect.

This is a pilot field study to investigate whether levels of consumers’ price promotion literacy and numeracy are adequate for everyday decision making. The information can be used as evidence and justification for further research.

The purpose of this paper is to evaluate the use, attitudes and perceptions of both teachers and students towards social media platforms (Facebook and Twitter) in healthcare higher education practice.

Systematic literature review. A search of published and unpublished databases was conducted from January 2000 to January 2013. Data were synthesised through a narrative approach. All included studies were critically appraised using Critical Appraisal Skills Programme appraisal tools.

From a total of 876 papers, 16 publications met the eligibility criteria. The review papers were largely of moderate methodological quality. The results indicated that Facebook and Twitter are perceived as potentially useful adjuncts in healthcare higher education practice. Their use as part of a “blended” approach to classroom teaching has been employed to enhance communication and increase accessibility of students to real-world practices and expertise. Whilst students perceive this to be of value, some have reservations regarding the possibility of faculty members spying or infringing on their “virtual” social community. Faculty members expressed some reservations regarding the perceived boundary between student-staff relationships.

This is the first paper to systematically review the literature on the use of social media networking sites in health education. This identified both the potential strengths and weaknesses of using this new technology, and highlights areas to expand knowledge with further research and practice.

Workers and construction professionals are generally not proficient in recognizing and managing safety hazards. Although valuable, traditional training experiences have not sufficiently addressed the issue of poor hazard recognition and management in construction. Since hazard recognition and management are cognitive skills that depend on attention, visual examination and decision-making, performance assessment and feedback in an environment that is realistic and representative of actual working conditions are important. The purpose of this paper is to propose a personalized safety training protocol that is delivered using robust, realistic and immersive environments.

Two types of virtual environments were developed: (1) Stereo-panoramic environments using real construction scenes that were used to evaluate the performance of trainees accurately and (2) A virtual construction site, which was used to deliver various elements of instructional training. A training protocol was then designed that was aimed at improving the hazard recognition and management performance of trainees. It was delivered using the developed virtual environments. The effectiveness of the training protocol was experimentally tested with 53 participants using a before–after study.

The results present a 39% improvement in hazard recognition and a 44% improvement in hazard management performance.

This study combines the benefits of using a virtual environment for providing instructional training along with realistic environments (stereo-panoramic scenes) for performance assessment and feedback. The training protocol includes several new and innovative training elements that are designed to improve the hazard recognition and hazard management abilities of the trainees. Moreover, the effectiveness of training in improving hazard recognition and hazard management is measured using specific outcome variables.

This paper aims to discuss research ethics in mixed-methods research (MMR) and MMR development with a focus on ethical challenges that stem from working with technical instruments such as mobile eye-trackers.

The case of an interdisciplinary mixed-methods development study that aimed at researching the impacts of emerging mobile augmented-reality technologies on the perception of public places serves as an example to discuss research-ethical challenges regarding (1) the practical implementation of the study, (2) data processing and management and (3) societal implications of developing instruments to track and understand human practices.

This study reports challenges and experiences in ethical decision-making in the practical implementation of the study regarding the relationship to research subjects, the use of mobile research instruments in public places and the interdisciplinary cooperation among research team members. Further, this paper expounds on ethical challenges and recommendations in data processing and management and with a view to societal implications of method development and the aspirations of transdisciplinarity. This study concludes that institutionalized ethics need to become more flexible, while applied ethics and reflection must make their entry into university curricula across disciplines.

Complex interdisciplinary mobile and mixed-methods projects that involve sensors and instruments such as mobile eye-trackers are on the rise. However, there is a significant lack of engagement with practical research ethical challenges, practices and requirements in both mixed-methods and method-development literature. By taking a context- and process-oriented perspective focusing on doing ethics, the paper contributes a concrete empirical case to these underdeveloped fields.

Explanations for voluntary or intentional childlessness range from macro-level forces, such as feminism and access to contraceptives, to micro-level or individual preferences, such as the prioritisation of leisure time over childrearing. However, some researchers contend that the decision (not) to have children is likely impacted by overlapping factors rather than a dichotomised characterisation of internal or external factors. This debate similarly reflects Pierre Bourdieu’s ‘third way’ theoretical and methodological orientation. Bourdieu argued against a false dichotomy between the influence of structure over an individual and the ability for individuals to make active, free choices. He instead claimed that the social world consists of a complex interplay of both individual and structural factors, which he conceptualised as habitus, capital and fields. This chapter initiates the link between current understandings of childbearing preferences with Bourdieu’s concepts of habitus (our taken-for-granted, internalised ideologies or identities), capital (economic, social, cultural and symbolic resources) and fields (the external social structures or institutions in which we interact) and proposes quantitative measures of childbearing habitus and capital.

This chapter consists of an exploratory comparison of characteristics of non-parents in relation to childbearing preferences, suggesting measures to identify deeply rooted childbearing habitus and the relationship between access to various forms of capital and the habitus. This study utilises survey responses from a sample of 972 childless men and women between 25 and 40 years of age, assessing measures of social support, cultural norms and economic resources in relation to participants’ preference to have or not to have children in the future. A multivariate nested logistic regression was conducted to explore the odds of identifying as voluntarily childless (VC) (not wanting or probably not wanting, to have children in the future) based on socio-demographic factors, as well as various measures of social, economic, cultural and symbolic capital. Findings indicate several variations in significant factors contributing to a preference to remain childfree. Measures of cultural capital, including gender ideologies and pronatalist ideologies, appeared to be the greatest predictors of childbearing habitus. These findings support research suggesting that VC adults are more egalitarian and less traditional in gender relations as well as pronatalist assumptions.

The educational attainment of rural people differs considerably based upon peoples' races and ethnicities. For example, in 2015 twice as many White rural adults had a bachelor's degree or higher compared to Black, American Indian and Alaska Native, and Hispanic or Latino rural adults. Within higher education contexts if one is to understand college students and their experiences, a recognition of students' identities is necessary. For African American college students from rural areas, I argue a starting point for understanding these students and their experiences in college environments is an exploration of the intersection of their place-based and race/ethnicity-based identities. This chapter, therefore, provides statistics about the educational attainment of rural people, reviews rural place–based identity literature, and then integrates perceptions of place with perceptions of race and ethnicity. Based on this discussion, recommendations for future pedagogies, practices, and research are suggested for faculty, staff, and scholars.

The purpose of the paper is to discuss the “Q-Step in the Community” programme, part of the Q-Step Centre based in the Sociology Department at Manchester Metropolitan University, designed to help address the skills gap in quantitative methods (QM) that is evident across parts of the UK higher-education sector. “Q-Step in the Community” is a data-driven work-based learning programme that works in partnership with local organisations to provide placement opportunities for final year undergraduates and postgraduates. Students conduct a quantitative research project, which is typically identified by the placement provider.

The authors use quantitative and qualitative feedback from students and placement providers, along with our own reflections on the process to evaluate the placement programme. Data were collected through a focus group and email interviews with placement providers, along with a questionnaire, which was distributed to “Q-Step in the Community” alumni.

Data-driven work-based learning opportunities allow students to develop and demonstrate their quantitative skills and support networking opportunities whilst also developing valuable soft-skills experience of the workplace that develops their career-readiness. In addition, those opportunities provide valuable research for placement providers, which support their sustainability and enhance their service delivery.

The research focusses solely on one programme at one university offering quantitative data driven work-based learning opportunities at undergraduate and post-graduate level. It is not possible to make valid comparisons between those who do a placement with those who do not.

Views of key stakeholders in the process have been sought for this research, which can be useful to consider for others considering developing similar programmes for their students.
