Social integration and social involvement from a societal and individual perspective -- Social involvement and labor market participation as individual value creation -- The effect of unemployment on social involvement: Main and heterogeneous effects.

Sommario/riassunto

People’s involvement in social groups and networks constitutes a resource for societies and individuals. More specifically, involvement represents the basis upon which social integration takes place and provides access to material and non-material goods considered to be rewarding for individuals. Despite substantial research suggesting that unemployment triggers social exclusion and social isolation, evidence for the causal influence of unemployment on social involvement is limited. Past studies typically have relied on research methods that are unable to address causality. Using long-term panel data from Germany and panel estimation methods, Bettina Sonnenberg investigates the causal effects of unemployment on people’s social involvement. By taking into account selection confounds, she shows that findings from cross-sectional research are misleading and have advanced inaccurate conclusions regarding the social consequences of unemployment.  Contents   Social integration and social involvement from a societal and individual perspective  Social involvement and labor

Sommario/riassunto

The cycling of energy and elements in aquatic environments is controlled by the interaction of autotrophic and heterotrophic processes. In surface waters of lakes, rivers, and oceans, photosynthetic microalgae and cyanobacteria fix carbon dioxide into organic matter that is then metabolized by heterotrophic bacteria (and perhaps archaea). Nutrients are remineralized by heterotrophic processes and subsequently enable phototrophs to grow. The organisms that comprise these two major ecological guilds are numerous in both numbers and in their genetic diversity, leading to a vast array of physiological and chemical responses to their environment and to each other. Interactions between bacteria and phytoplankton range from obligate to facultative, as well as from mutualistic to parasitic, and can be mediated by cell-to-cell attachment or through the release of chemicals. The contributions to this Research Topic investigate direct or indirect interactions between bacteria and



phytoplankton using chemical, physiological, and/or genetic approaches. Topics include nutrient and vitamin acquisition, algal pathogenesis, microbial community structure during algal blooms or in algal aquaculture ponds, cell-cell interactions, chemical exudation, signaling molecules, and nitrogen exchange. These studies span true symbiosis where the interaction is evolutionarily derived, as well as those of indirect interactions such as bacterial incorporation of phytoplankton-produced organic matter and man-made synthetic symbiosis/synthetic mutualism.
