Research also suggests what biological changes take place in a particular disorder as well as nature of risk which arises from psychological, social and environmental conditions. However it remains unclear how these psychosocial and environmental risk factors interact with biological factors which lead to clinical syndromes. This paper examines interrelationship of psychosocial and environmental risk and biological changes observed in mental disorders and tries to identify the possibility of a pathway of the psychopathology of psychiatric disorders. The review aims to demonstrate that significant advances in the fields of psychosocial, cultural, anthropological and neurobiological research provide novel insights into the etiology of mental disorders. There are neurochemical, functional and structural neurobiological, neurocognitive, immunological findings and findings from gene-environment interaction that appears promising. However these findings are in an isolated manner. Comprehensive studies examining major biological changes together in relation to psychosocial risk factors are lacking. Every individual reacts differently to the same environmental risk while there tends to be similarities in individual outcome in response to such stressors. The findings though robust independently, remain very preliminary to suggest a sequential trajectory for developing a clear pathway for pathogenesis. It is currently unclear whether there is a differential psychopathological impact of psychosocial stressors in different cultures despite the extensive variability both between and within major social groups and societies. Further research investigating modifiable and non-modifiable risk factors in context of prevailing socio-economic conditions is urgently needed to plan effective interventions.展开更多

The occurrence and impacts of disasters including the education sector can be studied through a social problem lens. This paper draws meaning and understanding of DRR education using the sociological disciplinary framework in a detailed qualitative case study of three schools as they responded to the devastating Gorakha earthquake in 2015 and other disasters in Nepal. This paper considers the three sub-disciplines of sociology: the sociology of disaster, the sociology of education and the sociology of education governance in a development context. These sub-disciplines are nested together to analyse social, political and historical factors and their relationships which are helpful to identify risks and vulnerabilities in the education sector in Nepal. These are the major areas to explore the disaster context and needs of context-specific education acts (hereafter DRR education) to minimise the potential risks of disasters. The article concludes that the social disciplinary framework is significantly useful to analyse DRR education provisions and implications of education governance to mobilise school in disaster preparedness, response and recovery.展开更多

Consumers need to obtain this information from producers or social networks, trust in the information,and consequently assess perceived risks, especially when food scandals are exposed to the media. In this study, we introduce the social embeddedness theory to understand how consumers’ social activities affect their risk perceptions on traceable food. Specifically, we investigate how risk perceptions are predicted by the interpersonal relationships, organizational level and social-level relationships. Results show that the interpersonal relationships were associated with lower levels of risk perceptions, while organizational and social relationships impacted consumer’s risk perceptions at middle and higher levels,respectively. Results also show that the "ripple effect" extended to effect of risk events with negative information, however,did not exist for the group exposed to positive information. Potential food safety implications have been proposed to identify for effective risk mitigation under media coverages.展开更多

However, existing CA models for simulating sustainable urban development, though increasingly refined in modeling urban growth, capture mostly the environmental aspect of sustainability. In this study, an adaptable risk-constrained CA model was developed by incorporating the social-ecological risks of urban development. A three-dimensional risk assessment framework was proposed that explicitly considers the environmental constraints on, system resilience to, and potential impacts of urban development. The risk-constrained model was then applied to a case study of Sheyang County, Jiangsu Province in the eastern China. Comparative simulations of urban development in four contrasting scenarios were conducted, namely, the environmental suitability constrained scenario, the ecological risk constrained scenario, the social risk constrained scenario, and the integrated social-ecological risk constrained scenario. The simulations suggested that considering only environmental suitability in the CA simulation of urban development overestimated the potential of sustainable urban growth, and that the urbanization mode changed from city expansion that was more constrained by social risks to town growth that was more constrained by ecological risks. Our risk-constrained CA model can better simulate sustainable urban development; additionally, we provide suggestions on the sustainable urban development in Sheyang and on future model development.展开更多

Background: Few published work has investigated the relative risks of social participation, demographic, socioeconomic and disease factors with malnutrition in community-living older people, this study is to investigate the associations of these risk factors on the nutritional status in better nutrition support for the old age group. Design: A crosssectional study. Methods: It was a secondary analysis of a database in a mobile community centre between January 2008 and December 2009. One thousand seven hundred and thirty one participants aged between 54 and 103 were collected. With 319 full Mini Nutritional Assessment (MNA) completed, the participants’ demographic, socio-economic data, diseases, and nutritional status were analyzed with relative risk and 95% confidence interval level to identify the factors that make them vulnerable to nutritional risk. Results: The prevalence of malnutrition in the community-dwelling old was 3.95% and 83.7% of the sample was at risk of malnutrition. Living on allowances, young old who was socially engaged and good relationship with family members were at less risk to malnutrition. Conclusions: Special attention should be taken to these groups as they are prone to develop malnutrition.展开更多
