TL;DR: A two-dimensional stress-grain size deformation-mechanism map is proposed for the mechanical behaviour of nanocrystalline f.c. c.
Abstract: Molecular-dynamics simulations have recently been used to elucidate the transition with decreasing grain size from a dislocation-based to a grain-boundary-based deformation mechanism in nanocrystalline f.c.c. metals. This transition in the deformation mechanism results in a maximum yield strength at a grain size (the 'strongest size') that depends strongly on the stacking-fault energy, the elastic properties of the metal, and the magnitude of the applied stress. Here, by exploring the role of the stacking-fault energy in this crossover, we elucidate how the size of the extended dislocations nucleated from the grain boundaries affects the mechanical behaviour. Building on the fundamental physics of deformation as exposed by these simulations, we propose a two-dimensional stress-grain size deformation-mechanism map for the mechanical behaviour of nanocrystalline f.c.c. metals at low temperature. The map captures this transition in both the deformation mechanism and the related mechanical behaviour with decreasing grain size, as well as its dependence on the stacking-fault energy, the elastic properties of the material, and the applied stress level.

TL;DR: It is shown in a mouse model that influenza infection acutely induced airway hyper-reactivity (AHR), a cardinal feature of asthma, independently of T helper type 2 (TH2) cells and adaptive immunity.
Abstract: Patients with asthma, a major public health problem, are at high risk for serious disease from influenza virus infection, but the pathogenic mechanisms by which influenza A causes airway disease and asthma are not fully known. We show here in a mouse model that influenza infection acutely induced airway hyper-reactivity (AHR), a cardinal feature of asthma, independently of T helper type 2 (T(H)2) cells and adaptive immunity. Instead, influenza infection induced AHR through a previously unknown pathway that required the interleukin 13 (IL-13)-IL-33 axis and cells of the non-T cell, non-B cell innate lymphoid type called 'natural helper cells'. Infection with influenza A virus, which activates the NLRP3 inflammasome, resulted in much more production of IL-33 by alveolar macrophages, which in turn activated natural helper cells producing substantial IL-13.

TL;DR: In Studies 5-7, the authors develop and demonstrate the reliability and validity of brief, 7-item scales that can be used to assess the facets of pride in future research.
Abstract: To provide support for the theoretical distinction between 2 facets of pride, authentic and hubristic (J. L. Tracy & R. W. Robins, 2004a), the authors conducted 7 studies. Studies 1-4 demonstrate that the 2 facets (a) emerge in analyses of the semantic meaning of pride-related words, the dispositional tendency to experience pride, and reports of actual pride experiences; (b) have divergent personality correlates and distinct antecedent causal attributions; and (c) do not simply reflect positively and negatively valenced, high- and low-activation, or state versus trait forms of pride. In Studies 5-7, the authors develop and demonstrate the reliability and validity of brief, 7-item scales that can be used to assess the facets of pride in future research.

TL;DR: Empirical evidence is found that wealthier individuals and individuals employed in professional occupations exhibit a lower disposition effect, and trading frequency also tends to reduce the disposition effect.
Abstract: This paper analyzes the trading records of a major discount brokerage house to investigate the disposition effect, the tendency to sell stocks that have appreciated in price (winners) sooner than stocks that trade below the purchase price (losers). In contrast to previous research that has demonstrated the disposition effect by aggregating across investors, our main objective is to identify differences in the disposition bias across individuals and explain this in terms of underlying investor characteristics. Building on the findings in experimental economics and social psychology, we hypothesize that differences in investor literacy about financial markets and trading frequency are responsible in part for the variation in individual disposition effect. Using demographic and socioeconomic variables as proxies for investor literacy, we find empirical evidence that wealthier individuals and individuals employed in professional occupations exhibit a lower disposition effect. Consistent with experimental economics, trading frequency also tends to reduce the disposition effect. We provide guidelines for investment advisors, regulators, and investment communities to utilize our findings and help investors make better decisions.
