TL;DR: In this paper, the authors focus on assessing soil quality and health to define the sustainability of land management practices and to translate scientific knowledge and information on soil function into practical tools and approaches by which land managers can assess the sustainable of their management practices.

TL;DR: It is demonstrated that the stress gradient generated by the tip of an atomic force microscope can mechanically switch the polarization in the nanoscale volume of a ferroelectric film, enabling applications in which memory bits are written mechanically and read electrically.
Abstract: Ferroelectric materials are characterized by a permanent electric dipole that can be reversed through the application of an external voltage, but a strong intrinsic coupling between polarization and deformation also causes all ferroelectrics to be piezoelectric, leading to applications in sensors and high-displacement actuators. A less explored property is flexoelectricity, the coupling between polarization and a strain gradient. We demonstrate that the stress gradient generated by the tip of an atomic force microscope can mechanically switch the polarization in the nanoscale volume of a ferroelectric film. Pure mechanical force can therefore be used as a dynamic tool for polarization control and may enable applications in which memory bits are written mechanically and read electrically.

TL;DR: In this paper, the authors examined the relationship between human resources and psychological capital of Chinese workers and their performance in three factories (two private and one state-owned) in the People's Republic of China.
Abstract: Everyone knows about China's huge population and the fast-growing economy. Although macro-level sociological and economic analyses have given some attention to the linkage between the two, at the micro level, the relationship between human resources and, more specifically, psychological capital of Chinese workers and their performance has been largely ignored. Within the context of three factories (two private and one state-owned) in the People's Republic of China, this exploratory study examined the relationship of a sample (n=422) of Chinese workers’ positive psychological capital states and their performance. Results indicated the workers’ positive states of hope, optimism, and resiliency, separately and when the three were combined into a core construct of psychological capital, significantly correlated with their performance, as rated by their supervisors. An analysis of workers in one of the factories (n=272) also found a significant relationship between the workers’ positive psychological capital and the performance outcome of relative merit-based salary. Limitations, future research, and practical implications conclude the article.

TL;DR: A sizable difference in magnetic moments of Fe and Ti atoms at the two interfaces dissimilar by the orientation of the local electric dipole moments is shown.
Abstract: An unexplored physical mechanism which produces a magnetoelectric effect in ferroelectric-ferromagnetic multilayers is studied based on first-principles calculations. Its origin is a change in bonding at the ferroelectric-ferromagnet interface that alters the interface magnetization when the electric polarization reverses. Using Fe/BaTiO3 multilayers as a representative model, we show a sizable difference in magnetic moments of Fe and Ti atoms at the two interfaces dissimilar by the orientation of the local electric dipole moments. The predicted magnetoelectric effect opens a new direction to control magnetic properties of thin-film layered structures by electric fields.

TL;DR: Estimating future food production capacity would benefit from an analysis of past crop yield trends based on a robust statistical analysis framework that evaluates historical yield trajectories and plateaus, which shows the relative rate of gain decreases over time.
Abstract: Food security and the conservation of natural ecosystems largely rely on the increase in crop yields. Here, the authors examine global crop yield trends since 1960, and establish a robust statistical framework for estimating historical trajectories and identifying yield plateaus.
