摘要：
The purpose of this paper is to analyze the influencing factors of sustainable development of family grain farms in China. According to related investigation, there is a real problem of lack of social responsibility of grain family farms in China, which restricts their sustainable development. Therefore, based on a sample of 301 family grain farms in China, this paper used multi-classification ordered logit model and mediation effect model to investigate the relationship between perceptions of social responsibility, resource integration ability, and sustainable development of family grain farms. Various studies show that stronger perceptions of social responsibility related to more sustainable development; greater resource integration ability related to more sustainable development; and resource integration ability mediated the relationships between perceptions of social responsibility and sustainable development. Conclusions suggest that improving perceptions of social responsibility, increasing support for improving resource integration ability and giving full play to the mediating role of resource integration ability is needed to bolster the sustainable development of family grain farms.

The pace of aging is accelerating, and concurrently, an increasing number of elderly individuals are grappling with loneliness. Using KHB method and secondary moderating effect test, authors apply the concept of multi-dimensional loneliness in an exploratory study of eldercare service purchase behavior among elderly people based on national sample in China. Results show that, firstly, loneliness serves as a significant motivator driving the consumption behavior of elderly care services. Secondly, the varying degrees of loneliness differentially impact the consumption behavior of elderly individuals receiving eldercare services. Mild loneliness manifests as a facilitative effect, whereas severe loneliness manifests as an inhibitory effect. Thirdly, emotional loneliness promotes the consumption behavior of lonely elderly individuals towards eldercare services, whereas social loneliness is unrelated to the consumption of eldercare services among lonely elderly individuals. Lastly, emotional support from adult children incentivizes lonely elderly individuals to invest in care-related eldercare services, displacing their expenditure on mental well-being-focused eldercare services. The findings of this paper confirm the multidimensional nature of loneliness within the context of elderly care services, laying the groundwork for future research on the significance of elderly care services in enhancing the psychological well-being of the elderly population.

摘要：
Based on the micro-survey data of 424 family farms in Hunan Province in 2022, this study employs the propensity score matching method to empirically examine the impact of joining cooperatives on the supply level of agricultural socialized service by family farms. The study indicates that joining cooperatives can significantly improve the supply level of agricultural socialized services by family farms; The impact of joining cooperatives varies for different types of agricultural socialized services; Enhancing the awareness of agricultural socialized services among family farmers serves as an intermediary approach for cooperatives to facilitate the provision of agricultural socialized services to small-scale farmers. Hence, it is imperative to proactively encourage family farms to participate in cooperatives, enhance the promotion of agricultural socialized services, and offer policy assistance to enhance the supply level of agricultural socialized services for family farms.
摘要：
Improving low nitrogen (LN) tolerance in barley (Hordeum vulgare L.) increases global barley yield and quality. In this study, a recombinant inbred line (RIL) population crossed between “Baudin × CN4079” was used to conduct field experiments on twenty traits of barley yield, agronomy, and nitrogen(N)-related traits under LN and normal nitrogen (NN) treatments for two years. This study identified seventeen QTL, comprising eight QTL expressed under both LN and NN treatments, eight LN-specific QTL, and one NN-specific QTL. The localized C2 cluster contained QTL controlling yield, agronomic, and N-related traits. Of the four novel QTL, the expression of the N-related QTL Qstna.sau-5H and Qnhi.sau-5H was unaffected by N treatment. Qtgw.sau-2H for thousand-grain weight, Qph.sau-3H for plant height, Qsl.sau-7H for spike length, and Qal.sau-7H for awn length were identified to be the four stable expression QTL. Correlation studies revealed a significant negative correlation between grain N content and harvest index (p < 0.01). These results are essential for barley marker-assisted selection (MAS) breeding.
