What motivates adult children, parents, and even grandchildren to live together? To answer this question, we review the sociological and social gerontological research on multigenerational households and families. We first provide a snapshot of multigenerational coresidence in the US and then discuss the primary theoretical perspectives used to explain these patterns: exchange theory, altruism, and norms and obligations. Structural conditions including economic crises tend to facilitate adult children moving in with parents (often with dependent children in tow), while spousal loss and declining health act as catalysts for parents moving in with adult children. Furthermore, economic struggles often facilitate the formation of grandparent-headed families where the middle generation parents may or may not be present. We suggest that the current economic recession and housing crises will have profound effects on multigenerational households and may also encourage more coresidence. Changes in social welfare policies, increases in coresident grandparenting, and changes in the racial and ethnic composition of the US also have implications for multigenerational households’ economic and social security. 相似文献
Starting from the idea that relational sociology has been founded on various and incompatible social ontologies, I argue that it is at risk of losing its raison d'être if we do not answer two fundamental practical and ontological questions: (1) Why do we need relational sociology? and (2) What do we study in relational sociology? In this respect, I propose a deep, transactional sociology partly and freely inspired by the work of J. Dewey which clearly detaches relational sociology from social determinism and co-determinism. 相似文献
This article uses a case study from Ghana to argue that rights-based legal instruments are important but insufficient steps towards securing disability rights in non-western societies. Despite Ghana’s implementation of a Disability Act and ratification of the United Nations Convention on the Rights of Persons with Disabilities, a grassroots perspective shows that legislation and the model of legal empowerment will not automatically produce equal access to human rights. The paper will present this argument through a case study of an individual who became disabled in 2008 and struggled for four years to secure his rights to healthcare and employment. I also argue that the case has a wider significance for disability rights in Ghana and beyond. 相似文献
Urban and technogenic landscapes in subarctic zones are not considered comfortable habitats for soil microbiota. However, green infrastructures in polar cities can provide a new niche for the development of a microbial soil community. Soil microbial biomass and the diversity of cultivable microfungi have been studied in relation to the chemical and morphological properties of urban soils in the polar city of Apatity. The quantitative indicators based on fluorescence microscopy and PCR real-time methods as well as the qualitative composition of the cultivable microfungal community were used to characterize the microbial community. Changes in the morphological and chemical composition of urban soils included a shift in pH and increased C and N content compared with forest soil. Studies have shown that the biomass of microfungi and actinomycetes in urban soils was lower than in forest soils and equals 0.12–0.19 mg/g and 0.06–0.44?×?10?3 mg/g, respectively. Bacterial biomass, on the contrary, increased in urban soils up to 2.6?×?10–3 – 5.6?×?10–3 mg/g. The number of ITS gene copies of fungi in urban soils varied from 5.0?×?109 to 1.45?×?1010 copies/g of soil, reaching the highest values in the courtyard. The number of rRNA gene copies of bacteria and archaea in urban soils increased compared with forest soil and amounted to 2.37?×?1010 – 9.99?×?1010 and 0.4?×?1010 – 0.8?×?1010 copies/g of soil, respectively. In urban soils, morphological changes in microfungi, including the predominance of small spores, were revealed in comparison with forest soils, where mycelium prevailed. An increase in the diversity of microfungi in urban soil and changes in the structure of their communities compared with forest soil was noted. Microfungi found in urban soils are not typical of the background soils of the region and would be expected in more southern conditions. Among them, opportunistic fungi species have been identified in humans, which increases the risk of diseases in residents of the northern region.

In Italy, the measure of the Equitable and Sustainable Well-being is provided by the Italian Institute of Statistics by means of a dashboard of basic and composite indicators. To investigate the dependence structure between the different domains of well-being, we propose the use of Non-Parametric Bayesian Networks based on the normal copula distribution, that allow to explore the conditional independence relationships between the composite indicators. The main advantage of the non-parametric models is that, as opposed to the parametric approach, they do not require any assumption on the marginal distributions of the variables. The proposed model is applied to the Equitable and Sustainable Well-being indicators measured at the provincial level and enriches the analysis of well-being by inspecting similarities and differences between Italian urban areas and territories.
