TL;DR: This review paper summarizes existing information regarding the effects of natural organic matter (NOM) on the fate and mobility of As species in the environment and development of proper geochemical conceptual models may provide means of predicting the role of NOM in arsenic leaching and/or immobilization.
Abstract: Arsenic (As) contamination in groundwater has received significant attention recently. Natural and anthropogenic sources contribute to the worldwide occurrence of As contamination. As speciation is an important factor related to its toxic and mobile behavior. The release of As from soils and sediments into groundwater is governed by several geophysicochemical processes, of which, As sorption behavior is of principle significance. This review paper summarizes existing information regarding the effects of natural organic matter (NOM) on the fate and mobility of As species in the environment. NOM may enhance the release of As from soils and sediments into the soil solution, thereby facilitating As leaching into the groundwater. The main influencing mechanisms include competition for available adsorption sites, formation of aqueous complexes, and/or changes in the redox potential of site surfaces and As redox speciation. NOM may also serve as binding agents, thereby reducing As mobility. However, comparably little research has been performed on this aspect. Since most investigations have been done on purified minerals under laboratory conditions, further research involving various geological materials under natural environmental conditions is required. Development of proper geochemical conceptual models may provide means of predicting the role of NOM in arsenic leaching and/or immobilization.

TL;DR: In this paper, meta-analytical techniques employed on a database of 141 studies covering 28 different countries were used to find that affiliation diminishes firm performance in general, but also that affiliates are comparatively better off in contexts with underdeveloped financial and labor market institutions.
Abstract: Research on business groups—legally independent firms tied together in various formal and informal ways—is accelerating. Through meta-analytical techniques employed on a database of 141 studies covering 28 different countries, we synthesize this research and extend it by testing several new hypotheses. We find that affiliation diminishes firm performance in general, but also that affiliates are comparatively better off in contexts with underdeveloped financial and labor market institutions. We also trace reduced affiliate performance to specific strategic actions taken at the firm and group levels. Overall, our results indicate that affiliate performance reflects complex processes and motivations.

TL;DR: This analysis has emerged from the joint consideration of how both appetitive and defensive behaviours are influenced by dopamine antagonists, along with an examination of dopamine release during sequences of behaviour, suggesting that dopamine is involved in fundamental psychological processes through which environmental stimuli come to exert control over certain aspects of behaviour.

TL;DR: In this article, the authors defined the definition of a Born Global (BG) firm and described the three phases through which BGs progress: introductory, growth and resource accumulation, and break-out to independent growth.
