The Flemish Examination Centre designed an intervention to establish a professional learning community on the topic of writing assessment. The purpose of this paper is to investigate the effects of this intervention and explain how this intervention succeeded in establishing a professional learning community.

A mixed method design was used to answer the research questions. Quantitative analysis of comparative judgement data provided insight into the effects of the intervention. More specifically was analysed whether examiners judged more in line after the intervention. Qualitative analysis of the conversations within the intervention served to examine how interdependent examiners behaved in the professionalisation exercises and to gain insight into how a professional learning community was established.

The analysis showed that the intervention of the Flemish Examination Centre facilitated the formation of a professional learning community. This was visible in the quantitative analysis. The qualitative analysis showed that highly interdependent activities were helpful in establishing the professional learning community.

This study shows that interactions of high interdependence are beneficial to facilitate professional learning communities.

This study shows that the assessment data can guide a well-thought out design of interventions to establish professional learning communities among assessors. Assessment data can be a guidance for supportive group constellations and discussions to improve assessment practices. The key in this regard lies in the level of interdependence that is created among participants.

This study examines what social ties within collectivist settings mean for women's venturing and how these ties support women in gaining empowerment through their ventures.

Thirteen in-depth semi-structured interviews with women entrepreneurs located in the United Arab Emirates (UAE) were conducted to examine the influence of social ties in their ventures.

The findings reveal that women in this context, contrary to most reported findings in the extant literature, both rely more on and find strong ties more conducive than weak ties in most of their entrepreneurial behaviours and activities. Results also show how the UAE's collectivist cultural norms shape social networks and inform individual decision-making, resource acquisition, well-being and self-efficacy as well as enhance women's empowerment through entrepreneurship. The women entrepreneurs were found to leverage their social ties for both power and action throughout their entrepreneurial journey consistent with their culture.

A conceptual model, derived from the results of a qualitative study, illustrating the relationships between women entrepreneurs' use of social ties and the empowering capacities of venturing within a collectivist cultural context is developed. Based on these findings, the authors discuss the implications for policymakers and recommend avenues for future research, and research designs, on women entrepreneurs in collectivist contexts.

This paper aims to depict the mechanistic role of vitamin D on dementia prevention, relief of the severity and the complication of the disease. All papers indexed in scientific databases, including Scopus, Elsevier, PubMed, Embase and Google Scholar between 2000 and 2021 were extracted and discussed. To present the mechanistic role of vitamin D in declining the severity of dementia, keywords including dementia, vitamin D, oxidative stress, inflammation, amyloid beta-Peptides were used.

Dementia is a prevalent cognitive disorder worldwide, especially in elderly people, which is accompanied by serious disabilities. Besides genetic, biological and lifestyle factors are involved in the incidence of dementia. An unhealthy diet along with micronutrient deficiencies are among modifiable factors. Vitamin D is one of the important micronutrients in brain health. Besides the involvement in gene expression, bone mineralization, apoptosis, inflammation, skeletal maturation, neurotropic action and hemostasis of phosphate and calcium, vitamin D also exerts neuroprotective effects via genomic and non-genomic pathways.

Vitamin D up-regulates the expression of various genes involved in dementia incidence via various mechanisms. Decreasing oxidative stress and the neuro-inflammatory cytokines levels, regulation of the expression of alternated Proteins including Tau and Amyloid-ß, calcium homeostasis in the central nervous system and also vascular are considered main mechanisms.

Considering the importance of diet in preventing dementia, adherence to a healthy diet that provides essential nutrients to brain function seems to be urgent. Controlling serum levels of vitamin D periodically and providing vitamin D by related sources or supplements, if there is a deficiency, is recommended. Future studies are needed to clarify other related mechanisms.
