Individual and environmental factors associated with tobacco smoking, alcohol abuse and illegal drug consumption in university students: a mediating analysis
(MDPI AG, 2020-04-27)[Abstract] Substance abuse is a major and prevalent public health concern among university students. Tobacco smoking, risky alcohol behavior, and illegal drug consumption may lead to health problems and behavioral and ... -
Individual Social Capital and Subjective Wellbeing: The Relational Goods
(Springer, 2017)[Abstract] In this paper we analyze the non-instrumental dimension of social capital and its effects on subjective well-being. In the first part, we define the characteristics of production and consumption of relational ... -
Individual Well-Being, Geographical Heterogeneity and Social Capital
(Springer, 2018)[Abstract] This paper argues the relevance of analysing the origins of contextual effects to explain subjective well-being (SWB). Using the 2012 European Social Survey, the study applies social capital indicators to ... -
Individual, job, and organizational dimensions of work engagement: evidence from the tourism industry
