This paper aims to better understand how accountability for sustainability takes shape within organisations and specifically, what makes employees act in a Swedish local authority. This aim moves beyond the prevalent external face of accountability in social and environmental accounting research by observing how employees understand and act upon their multiple accountability demands.

This paper adopts a single case study approach within a Swedish local authority, drawing from qualitative data including semi-structured interviews, site visits and governing documents.

Sustainable action is not only the product of hierarchically enforced structural accountabilities and procedures but often must be reconciled with the personal perspectives of the public sector employees involved as part of an accountability dynamic. Additionally, the findings reveal that hierarchical accountability, rather than serving to individualise and isolate employees, acts as a prompt for the more practical and personal reconciliations of accountability with the ethics and experiences of the individual involved.

Greater consideration to employee socialisation processes in public sector organisations should be given to reinforce organisational governance systems and controls, and thus help ensure sustainable behaviour in practice.

Employee socialisation processes are important for the development of sustainable practices both within and beyond organisational boundaries.

This study considers the interrelatedness of hierarchical and socialising accountability measures and contributes towards the understanding of the relationship between these two accountability forms, contrary to previous understandings that emphasise their contrasting nature and incompatibility.

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.
