TL;DR: In this paper, the authors evaluated the efficacy of an intensive four-day contact intervention (a peace workshop) organized in Sri Lanka and represented an initial step toward understanding the long-term impact of such interventions on attitudes and behaviors in the context of protracted ethnic conflict.
Abstract: The current study evaluates the efficacy of an intensive four-day contact intervention (a peace workshop) organized in Sri Lanka and represents an initial step toward understanding the long-term impact of such interventions on attitudes and behaviors in the context of protracted ethnic conflict. Compared with two control groups, the participant group showed greater empathy toward members of the “other”ethnicity, even one year after participation in the peace workshops. Consistent with the attitudinal data on empathy, participants donated more money to help poor children of the “other” ethnicity than did nonparticipants. Implications are discussed.

TL;DR: In this paper, two regression models were developed incorporating nine socio-economic variables, which showed that involvement in non-farm and non-forestry employment, high agricultural income, higher agricultural productivity, better education and incorporation of local communities into the outside markets can reduce dependency on forest resources.

TL;DR: It is shown for the first time that an acute increase in luteal BF occurs in the peripheral vasculature of the mature CL together with increases in eNOS expression and ET-1 and Ang II secretion in the CL during the early stages of luteolysis in the cow.

TL;DR: The results indicate that environmentally regulated biophysical constraints and light availability are the first‐order drivers of global photosynthetic capacity, thus maximizing potential resource use for growth and reproduction.
Abstract: Earth system models (ESMs) use photosynthetic capacity, indexed by the maximum Rubisco carboxylation rate (Vcmax ), to simulate carbon assimilation and typically rely on empirical estimates, including an assumed dependence on leaf nitrogen determined from soil fertility. In contrast, new theory, based on biochemical coordination and co-optimization of carboxylation and water costs for photosynthesis, suggests that optimal Vcmax can be predicted from climate alone, irrespective of soil fertility. Here, we develop this theory and find it captures 64% of observed variability in a global, field-measured Vcmax dataset for C3 plants. Soil fertility indices explained substantially less variation (32%). These results indicate that environmentally regulated biophysical constraints and light availability are the first-order drivers of global photosynthetic capacity. Through acclimation and adaptation, plants efficiently utilize resources at the leaf level, thus maximizing potential resource use for growth and reproduction. Our theory offers a robust strategy for dynamically predicting photosynthetic capacity in ESMs.

TL;DR: This article used data from surveys in Sri Lanka to compare the characteristics of self-employed workers with wage workers and with owners of larger firms and found that two-thirds to three-quarters of the own account workers have characteristics which are more like wage workers than larger firm owners.
Abstract: Is the vast army of the self-employed in low income countries a source of employment generation? This paper uses data from surveys in Sri Lanka to compare the characteristics of own account workers (non-employers) with wage workers and with owners of larger firms. The authors use a rich set of measures of background, ability, and attitudes, including lottery experiments measuring risk attitudes. Consistent with the International Labor Organization's views of the self employed (represented by Tokman), the analysis finds that two-thirds to three-quarters of the own account workers have characteristics which are more like wage workers than larger firm owners. This suggests the majority of the own account workers are unlikely to become employers. Using a two and a half year panel of enterprises, the authors show that the minority of own account workers who are more like larger firm owners are more likely to expand by adding paid employees. The results suggest that finance is not the sole constraint to growth of microenterprises, and provides an explanation for the low rates of growth of enterprises supported by microlending.
