农户农机社会化服务采纳意愿与行为偏差分析——基于江西省的调查

基于江西省50个县(区)635份农户微观调查数据,运用Logistic回归模型分析农户农机社会化服务采纳意愿与行为的偏差问题。结果表明：农户对农机社会化服务采纳意愿与行为存在一定的偏差,偏差率为10.8%,此偏差主要受农户受教育年限、对农机社会化服务的了解程度、周边农户对农机社会化服务的采纳情况、加入合作社、参加农业技能培训、水稻经营的土地面积因素影响。其中,是否使用互联网和水稻经营的土地面积会加深偏差程度,其他因素作用相反,是否参加农业技能培训和农机社会化服务的了解程度对偏差的影响程度最大。该研究结论对普及农机社会化服务服务知识,更好地制定和完善农机社会化服务发展政策,提升农机社会化服务采纳意愿与行为的转化具有重要的启示和借鉴意义。     

ALCOHOL CONSUMPTION IN RATS: EFFECTS OF INTRACRANIAL INJECTIONS OF ETHANOL

After permanent implantation of intraventricular cannulae, rats were repeatedly infused with ethanol solutions of several concentrations. Pro-nounced preferences were exhibited for ordinarily noxious ethanol without prior oral exposure to this fluid. Since preferences for ethanol remained unusually high after cessation of infusion, a permanent change may take place in the central nervous system. central nervous system.

旅游方案选择的消费者行为分析

旅游教研室设计的旅游方案研究人们的选择行为。实验结果显示,人的行为并没有体现经济理论假设中的完全理性,有时人的行为选择也会出现一种非理性。由于人的行为是受多种因素的影响,其中经济因素只是影响人类行为的一个方面,而经济行为受收入水平、消费者偏好、制度设计等多因素制约。可见,"人及其行为"应该成为经济学研究的核心和主题。     

The role of time preferences in contract breach: Evidence from Chinese poultry farmers participating in contract farming

Farmers’ contract breach behavior is cited as one of the major stumbling blocks in the sustainable expansion of contract farming in many developing countries. This paper examines farmers’ contract breach decisions from the perspective of time preferences. The empirical analysis is based on a household survey and economic field experiments of poultry households participating in contract farming conducted in Jiangsu Province, China. A discounted utility model and a maximum likelihood technique are applied to estimate farmers’ time preferences and the effect of time preferences on contract breach in the production and sales phases are explored with a bivariate probit model. The results show that, on average, the poultry farmers in the sample are generally present biased and impatient regarding future utility. The regression results show that farmers with a higher preference for the present and a higher discount rate are more likely to breach contracts, and time preferences play a greater role in the production phase than in the sales phase. When considering heterogeneity, specific investments and transaction costs promote contract stability only for farmers with a low degree of impatience. Moreover, compared with large-scale farmers, small-scale farmers’ contract breach decisions are more significantly affected by their time preferences. These results have implications for contract stability policies and other issues that are impacted by the linking of behavioral preferences to agricultural decisions.     

社会公益视角下的高校图书馆研究

高校图书馆从本质上具有社会公益性,社会化服务是其社会公益性的具体形式.高校图书馆为社会服务既是历史发展的必然要求,也是图书馆网络化和数字化发展的必然结果.高校图书馆社会公益性的实践探索有多种形式,包括面向社会读者开放、提供教育资源、参与公益活动以及为企业服务等.但是,高校图书馆为社会服务却受诸多因素的制约,有观念问题、服务能力问题和体制等问题.     

When does "economic man" dominate social behavior?

The canonical model in economics considers people to be rational and self-regarding. However, much evidence challenges this view, raising the question of when "Economic Man" dominates the outcome of social interactions, and when bounded rationality or other-regarding preferences dominate. Here we show that strategic incentives are the key to answering this question. A minority of self-regarding individuals can trigger a "noncooperative" aggregate outcome if their behavior generates incentives for the majority of other-regarding individuals to mimic the minority's behavior. Likewise, a minority of other-regarding individuals can generate a "cooperative" aggregate outcome if their behavior generates incentives for a majority of self-regarding people to behave cooperatively. Similarly, in strategic games, aggregate outcomes can be either far from or close to Nash equilibrium if players with high degrees of strategic thinking mimic or erase the effects of others who do very little strategic thinking. Recently developed theories of other-regarding preferences and bounded rationality explain these findings and provide better predictions of actual aggregate behavior than does traditional economic theory.     

基于CLV偏好挖掘模型的数字社区用户偏好挖掘研究

[目的/意义]数字社区已经成为企业高效管理用户的一种方式,用户行为信息以及用户的客户生命周期价值对数字社区的用户偏好挖掘具有重要意义。且现有的数字社区研究缺乏对用户价值和未来偏好挖掘的研究。[方法/过程]针对数字社区的用户群体,本文提出基于客户生命周期价值CLV (Customer Lifetime Value,CLV)的偏好挖掘模型CLV-PM(CLV-Preference Mining,CLV-PM)。首先,为反映用户真实偏好,基于用户行为信息,借助RFM模型和K-Means++算法挖掘用户群体特征,生成用户价值类别标签;其次,为考虑用户时序性和差异性以及增强模型对偏好的认知,利用用户CLV构建用户-评分矩阵,并借助协同过滤算法挖掘用户预测偏好;最后,绘制数字社区目标用户的用户偏好画像。[结果/结论]“微信社群”管理平台的用户数据集中,可划分为重要价值用户、低价值用户、回流用户和重要挽留用户4种用户价值类别;目标用户16254为重要价值用户,采取“留存和维持”为主的运营策略;历史偏好为欢乐跳一跳、秒杀等活动,预测偏好为飞行棋大作战、猜码图等活动,目标用户偏好画像为数字社区运营和维护...     

产权社会化

产权社会化与产权私有化、公有化之间既有区别又有联系。产权社会化作为一种经济制度,其合理性判断的依据是是否最大限度地实现社会公正。实现产权社会化是我国国有企业改革的最终出路。     

Neurochemical correlate of a spatial preference in rats

Spatial (left or right) preferences were determined for rats given foot shock in a T-maze. The animals were killed, and left and right striata were assayed separately for dopamine and left and right teldiencephalic regions were assayed for norepinephrine. Dopamine content was significantly higher (by 12 percent) in the striata contralateral to rats' side preferences than in the ipsilateral striata; there was no such difference for teldiencephalic norepinephrine. The small asymmetry in striatal dopamine content is not due to any learning- or stress-related change induced by the testing procedure but is probably inherent in normal rats. Some spatial behavior appears to be the manifestation of a normal and specific difference in the activity of left and right nigrostriatal systems.

社会功能重塑:公共危机应对中的城市社区商业转型研究——以F市地方传统商超为例

在突发公共危机事件背景下，城市社区商业积极参与抗疫防控行为引发社会对其社会功能的重新思考。调研发现，危机前后城市社区商业行为有了明显改变，由社会规范、聚集人群、社会化和社区意识组成的社区商业的社会功能从弱变强。危机中城市社区商业行为的变化不仅促进了零售机会的增加，还加强了与所属社区利益相关者之间的理解与沟通。因此，告别单一的经济功能，进一步推动城市商业社区社会功能的重塑，是实现城市社区商业转型的关键。     

Differences between tight and loose cultures: a 33-nation study

With data from 33 nations, we illustrate the differences between cultures that are tight (have many strong norms and a low tolerance of deviant behavior) versus loose (have weak social norms and a high tolerance of deviant behavior). Tightness-looseness is part of a complex, loosely integrated multilevel system that comprises distal ecological and historical threats (e.g., high population density, resource scarcity, a history of territorial conflict, and disease and environmental threats), broad versus narrow socialization in societal institutions (e.g., autocracy, media regulations), the strength of everyday recurring situations, and micro-level psychological affordances (e.g., prevention self-guides, high regulatory strength, need for structure). This research advances knowledge that can foster cross-cultural understanding in a world of increasing global interdependence and has implications for modeling cultural change.
