TL;DR: In this article, the peak stress dependence on strain rate and temperature was analyzed by means of the conventional constitutive equation and by a modified form, where the stress was substituted by the difference between stress and a threshold stress.

TL;DR: In this paper, the authors present a dynamic labour demand model where they evaluate the impact of employment regulations on permanent and temporary employment and find evidence in support of the hypothesis that fixed-term contracts have been effective steppingstones to permanent jobs during the period under observation.
Abstract: We present a dynamic labour demand model where we evaluate the impact of employment regulations on permanent and temporary employment. We consider three different kinds of regulations, namely firing costs, hiring costs and a constraint on temporary contracts. These regulations differently affect the size and composition of employment. The theoretical results are interpreted and questioned on the basis of empirical evidence on the employment effects of the regulation reforms that occurred in the major European countries in the period 1983–1999. The empirical analysis is based on a new set of time‐varying indicators on permanent employment protection, fixed‐term contracts and temporary agency work regulations. We find evidence in support of the hypothesis that fixed‐term contracts have been effective stepping‐stones to permanent jobs during the period under observation. On the contrary, flexible temporary agency work regulations seem to induce a substitution of permanent with temporary contracts.

TL;DR: The results suggest that because of the complex population structure associated with the ancestral divergence, subsequent bottlenecks in each gene pool, gene pool-specific domestication and intense selection within each gene Pool by breeders; association mapping would best be practised within each common bean gene pool.
Abstract: Wild common bean (Phaseolus vulgaris L.) is distributed throughout the Americas from Mexico to northern Argentina. Within this range, the species is divided into two gene pools (Andean and Middle American) along a latitudinal gradient. The diversity of 24 wild common bean genotypes from throughout the geographic range of the species was described by using sequence data from 13 loci. An isolation–migration model was evaluated using a coalescent analysis to estimate multiple demographic parameters. Using a Bayesian approach, Andean and Middle American subpopulations with high percentage of parentages were observed. Over all loci, the Middle American gene pool was more diverse than the Andean gene pool (πsil=0.0089 vs 0.0068). The two subpopulations were strongly genetically differentiated over all loci (Fst=0.29). It is estimated that the two current wild gene pools diverged from a common ancestor ∼111 000 years ago. Subsequently, each gene pool underwent a bottleneck immediately after divergence and lasted ∼40 000 years. The Middle American bottleneck population size was ∼46% of the ancestral population size, whereas the Andean was 26%. Continuous asymmetric gene flow was detected between the two gene pools with a larger number of migrants entering Middle American gene pool from the Andean gene pool. These results suggest that because of the complex population structure associated with the ancestral divergence, subsequent bottlenecks in each gene pool, gene pool-specific domestication and intense selection within each gene pool by breeders; association mapping would best be practised within each common bean gene pool.

TL;DR: In this paper, the authors propose an interpretation of the current Global Financial Crisis which emphasizes sectoral dislocation following localized technical change in the presence of barriers to labor mobility, reminiscent of a similar tale concerning the Great Depression.
Abstract: In this paper we propose an interpretation of the current Global Financial Crisis which emphasizes sectoral dislocation following localized technical change in the presence of barriers to labor mobility. This tale is reminiscent of a similar tale concerning the Great Depression. In the 30s technical change was localized in agriculture, where income fell because rising productivity could not be offset by a shrinking labor force due to the costs of moving out of agriculture for unemployed workers, inelastic demand for agricultural output meant that as output increased income declined. As individual incomes fell below the level necessary to finance the transition to manufacturing, excess labor became trapped in agriculture, reducing wages and exacerbating the rise in output. Shrinking incomes in agriculture reverberated on the other sectors, mainly manufacturing causing a large depression. Nowadays, it is manufacturing that plays the role of epicenter of technical change. Falling incomes in manufacturing yield a lack of demand for goods produced in the rest of the economy, namely the service sector. This may be the deep rooted cause of the long lasting slump and the painfully slow recovery.

TL;DR: Adipocyte-secreted BMP8b contributes to optimizing the thermogenic response by remodeling of the neuro-vascular networks in brown and white adipose tissue and are potential therapeutic targets in obesity.
Abstract: Activation of brown adipose tissue-mediated thermogenesis is a strategy for tackling obesity and promoting metabolic health. BMP8b is secreted by brown/beige adipocytes and enhances energy dissipation. Here we show that adipocyte-secreted BMP8b contributes to adrenergic-induced remodeling of the neuro-vascular network in adipose tissue (AT). Overexpression of bmp8b in AT enhances browning of the subcutaneous depot and maximal thermogenic capacity. Moreover, BMP8b-induced browning, increased sympathetic innervation and vascularization of AT were maintained at 28 °C, a condition of low adrenergic output. This reinforces the local trophic effect of BMP8b. Innervation and vascular remodeling effects required BMP8b signaling through the adipocytes to 1) secrete neuregulin-4 (NRG4), which promotes sympathetic axon growth and branching in vitro, and 2) induce a pro-angiogenic transcriptional and secretory profile that promotes vascular sprouting. Thus, BMP8b and NRG4 can be considered as interconnected regulators of neuro-vascular remodeling in AT and are potential therapeutic targets in obesity.
