Is Wife’s Marital Satisfaction Associated with Husband’s Dominance in Family Affairs? Empirical Evidence from China

Employing data from the China Family Panel Studies (CFPS), the paper empirically examines the relation between husband’s dominance in family affairs and wife’s marital satisfaction. While applying the ordinal probit model and ordinary least squares (OLS) method, the paper finds that wife’s reported marital satisfaction is positively associated with her husband’s dominant role in family affairs. This conclusion remains valid after using an instrumental variable to deal with endogeneity and performing some robustness tests. Some heterogeneities exist: the association is particularly prominent among those women who have traditional gender norms and are living in rural areas. These women tend to embrace the traditional gender ideology which stipulates that men are the masters of the family

Extrinsic Motivators and Contextual Performance of Communication and Media Teachers in Chinese Colleges and Universities

Communication and media teachers are a special group in Chinese colleges and universities, and it is essential to stimulate their positivity toward and enthusiasm for work. In this study, a model based on the extrinsic motivators of college communication and media teachers has been built to analyze the significant effect of the extrinsic motivators of college communication and media teachers on each element of contextual performance. It was found that salary and benefits have no significant effect on surrounding contextual performance, while organizational environment and personal development are positively related to surrounding relationships, and extrinsic motivators are positively related to organizational dedication performance

Why women’s entrepreneurial activities are low in China? The psychological perspective of self-esteem

How to increase women’s entrepreneurial activities and expand the proportion of female entrepreneurs among entire entrepreneurs has been the long-term focus of scholars. For the first time, this article uses the China Family Panel Studies (CFPS) and the National Survey on Women’s Social Status of China (NSWSS) to study why women’s entrepreneurial activities are relatively low in China from the psychological perspective of self-esteem. After controlling for related variables, the regression results show that self-esteem has a positive effect on women’s entrepreneurial activities. It indicates that the relatively low entrepreneurial activities of women are partially attributed to their low level of selfesteem. In addition, compared with cognitive ability and ‘The Big Five’ non-cognitive ability, self-esteem plays a greater role in explaining women’s entrepreneurial activities. While using propensity score matching and instrument variable methods to deal with the self-selection bias and endogenous problem of selfesteem, the results corroborate the conclusion. Further analysis indicates that social capital and risk-taking attitudes are two important mechanisms for self-esteem to influence women’s entrepreneurial activities. The attempt to incorporate the unique psychological trait of self-esteem into female entrepreneurship sheds light on the interdisciplinary research, and provides a new path for improving women’s entrepreneurial activities

High-Performance Nanofluidic Osmotic Power Generation Enabled by Exterior Surface Charges under the Natural Salt Gradient

High-performance osmotic energy conversion (OEC) requires both high ionic selectivity and permeability in nanopores. Here, through systematical explorations of influences from individual charged nanopore surfaces on the performance of OEC, we find that the charged exterior surface on the low-concentration side (surfaceL) is essential to achieve high-performance osmotic power generation, which can significantly improve the ionic selectivity and permeability simultaneously. Detailed investigation of ionic transport indicates that electric double layers near charged surfaces provide high-speed passages for counterions. The charged surfaceL enhances cation diffusion through enlarging the effective diffusive area, and inhibits anion transport by electrostatic repulsion. Different areas of charged exterior surfaces have been considered to mimic membranes with different porosities in practical applications. Through adjusting the width of the charged ring region on the surfaceL, electric power in single nanopores increases from 0.3 to 3.4 pW with a plateau at the width of ~200 nm. The power density increases from 4200 to 4900 W/m2 and then decreases monotonously that reaches the commercial benchmark at the charged width of ~480 nm. While, energy conversion efficiency can be promoted from 4% to 26%. Our results provide useful guide in the design of nanoporous membranes for high-performance osmotic energy harvesting.Comment: 30 pages and 7 figure

Quantifying the Economic Value of Evidence-Based Animal Selection on the inner Mongolian Desert Steppe

Inner Mongolian desert steppe in northwestern China suffers from significant grassland degradation, causing a decrease in producers\u27 income as well as negative off-site impacts (Kemp et al., 2013). Recent studies attribute this problem to a sudden increase in the stocking rate over the last half century, and thus development of an alternative farming system to reduce the animal number is urgently needed (Wang et al., 2011). Scientific experiments and modelling analyses have shown the potential of innovative systems that could deliver a win-win solution to local producers and environment (Li et al., 2015). However, the uptake of the proposed new technologies is generally slow because of the scepticism amongst producers, which is often augmented by the traditional herding culture whereby a large flock of animals is a symbol of social success (Kemp and Michalk, 2007). The objective of the present paper is to quantify the economic value of evidenced-based ewe selection, vis-à-vis random selection, the former of which could reduce the negative economic impact to producers due to the reduced stocking rate or, in some cases, even improve their long-term income (Kemp et al., 2011). A particular attention is paid to the carryover effect of an ewe\u27s body condition at an early stage of pregnancy on her lamb\u27s bodyweight at the annual sales time, a relationship relatively understudied in the preceding literature. Because lambs\u27 bodyweight is the most closely linked to economic benefits enjoyed by local producers specializing in meat production, a positive result from this study would be valuable information to convince them to adopt an alternative farming strategy

Plasminogen deficiency causes reduced angiogenesis and behavioral recovery after stroke in mice

Plasminogen is involved in the process of angiogenesis; however, the underlying mechanism is unclear. Here, we investigated the potential contribution of plasmin/plasminogen in mediating angiogenesis and thereby contributing to functional recovery post-stroke. Wild-type plasminogen naive (Plg(+/+)) mice and plasminogen knockout (Plg(-/-)) mice were subjected to unilateral permanent middle cerebral artery occlusion (MCAo). Blood vessels were labeled with FITC-dextran. Functional outcomes, and cerebral vessel density were compared between Plg(+/+) and Plg(-/-) mice at different time points after stroke. We found that Plg(-/-) mice exhibited significantly reduced functional recovery, associated with significantly decreased vessel density in the peri-infarct area in the ipsilesional cortex compared with Plg(+/+) mice. In vitro, cerebral endothelial cells harvested from Plg(-/-) mice exhibited significantly reduced angiogenesis assessed using tube formation assay, and migration, as evaluated using Scratch assays, compared to endothelial cells harvested from Plg(+/+) mice. In addition, using Western blots, expression of thrombospondin (TSP)-1 and TSP-2 were increased after MCAo in the Plg(-/-) group compared to Plg(+/+) mice, especially in the ipsilesional side of brain. Taken together, our data suggest that plasmin/plasminogen down-regulates the expression level of TSP-1 and TSP-2, and thereby promotes angiogenesis in the peri-ischemic brain tissue, which contributes to functional recovery after ischemic stroke

Grassland Rehabilitation through Re-Designing Livestock Management Systems

Grasslands are one of the most important land types supplying critical ecosystem services including feed for livestock grazing. They occupy ~54% of the world’s ice-free land surface. China contains the third largest area of grassland in the world, ~400 M ha, ~40% of China’s land surface. Chinese grasslands are severely degraded primarily due to overgrazing, which contributes to local poverty because of poor livestock production. To both recover the degraded grassland and to enhance the local herders’ income, a large farm-scale experiment was conducted in a desert steppe of Inner Mongolia, China from 2007 to 2012. We used a baseline survey, production models, and extension with government and private companies to test a redesigned grassland livestock management system. The new system employed summer grazing, winter greenhouse shed feeding, a reduction of overall stocking rate, lambing in summer (July), livestock infrastructure structure improvements, use of animal nutrient supplements, and incorporating crossbred Dorper and Mongolian sheep. This system showed positive advantages on animal production and household net income and transformed livestock production from a survival to a production enterprise. Of critical additional importance was that grassland rehabilitation occurred with the new management system, albeit slower than the more immediate positive changes to animal performance and herder net incomes. The integration of science, government and industry were key for this successful large-scale farm experiment

Biochar to improve soil fertility. A review

International audienceAbstractSoil mineral depletion is a major issue due mainly to soil erosion and nutrient leaching. The addition of biochar is a solution because biochar has been shown to improve soil fertility, to promote plant growth, to increase crop yield, and to reduce contaminations. We review here biochar potential to improve soil fertility. The main properties of biochar are the following: high surface area with many functional groups, high nutrient content, and slow-release fertilizer. We discuss the influence of feedstock, pyrolysis temperature, pH, application rates, and soil types. We review the mechanisms ruling the adsorption of nutrients by biochar
