所为非所想?农户风险管理意愿与行为的悖离分析

实现农户风险管理意愿与行为统一是降低农业风险对农户农业生产负面影响的重要途径。利用2018年东北三省和湖北省种植大户的调查数据,从自然风险与市场风险两方面,对农户风险管理的意愿、行为及其悖离进行分析,并探究形成悖离的原因。研究发现：对于自然风险,大部分农户使用了有效的风险管理工具,但风险管理意愿不高;农户的市场风险管理行为极为少见,与之相悖的是,农户具有较高的市场风险管理意愿。结果表明,风险管理实际行为控制、风险管理执行意愿和风险管理外部环境是影响农户自然风险管理意愿与行为悖离的主要因素;此外,农户对农业保险缺乏了解,以及目前农业保险存在的不足也是导致此悖离的重要原因;风险管理执行意愿和风险管理外部环境是影响农户市场风险管理意愿与行为悖离的主要因素。此外,农户获取信息渠道不足,对市场风险管理工具缺乏了解,甚至存在明显的误解与不信任也是导致农户市场风险管理意愿与行为悖离的重要原因。因此,为了有效实现农户风险管理意愿与行为的统一,应健全农业保险的推广机制,加强市场风险管理的宣传,扩大“保险+期货”的试点,发挥新型主体的带动作用。     

资源禀赋、电商认知与家庭农场主电子商务采纳行为

基于河北、江西和云南3省893个家庭农场调研数据,研究了资源禀赋、电商认知、政府扶持对家庭农场主电子商务采纳行为的影响机理。结果表明:资源禀赋中的家庭农场主受教育程度、电商培训和农产品特色明显程度对其电子商务行为采纳及采纳程度有显著正向影响;年龄、注册品牌、绿色或有机认证、产品深加工对采纳程度有显著正向影响;组织化和电商认知对电子商务采纳行为有显著正向影响;政府扶持对电子商务行为采纳具有显著正向影响,且对资源禀赋、电商认知 电子商务行为采纳及采纳程度关系中有正向调节效应。在此基础上,提出培育农产品电商品牌,提升农场主电商运营能力,创新电商经营模式和提高家庭农场组织化程度等建议。     

Passing Encounters East and West: Comparing Japanese and American Pedestrian Interactions

This study examined the microinteractions of pedestrians in Japan and in the United States as they walked past a confederate. Specifically, the effects of culture, condition (avoid, look-only, and look plus smile) and sex of confederate on glances, smiles, nods, and greetings by passing pedestrians were examined in a field study on over 1000 participants. The hypotheses of (1) lower responsiveness in Japanese pedestrians than in American pedestrians and (2) increased responsiveness as a function of condition were supported in a series of log-linear analyses of pedestrian glances, smiles, nods, and greetings. Both of these main effects were, however, qualified by Culture X Condition interactions on smiles, nods, and greetings, with the large condition effects present in the American pedestrians, but absent in the Japanese pedestrians. The results are discussed in terms of the functions of glances, smiles, nods, and greetings in these brief encounters and how differing cultural norms affect Japanese and American responsiveness. Finally, the limitations of this study and the broader utility of this research paradigm are discussed.

The Gender Gap in Orgasms: Survey Data from a Mid-Sized Canadian City

Objective: Previous research has established a gap in orgasm frequency between men and women. This study investigates explanations for the gender gap in orgasm. Methods: Crosstab analysis and logistic regression are used to examine the gender gap in orgasms from one Canadian city: Hamilton, Ontario (N = 194). Results: We find a strong association between women’s orgasms and the type of sexual behavior in which partners engage. Women who receive oral sex are more likely to reach orgasm. Conclusion: Sexual practices focused on clitoral stimulation are important to reducing the gender gap in orgasms.     

Beliefs underlying stress reduction and depression help-seeking among college students: An elicitation study

Objective: This study illustrates how a theory-based approach can identify college students’ beliefs about stress reduction activities and help-seeking for depression. These beliefs are the basis for intervention design. Participants: A sample of 53 undergraduate students at a public university in the Midwest participated in this research during March 2016. Methods: An open-ended belief elicitation survey was administered online. Beliefs were identified through qualitative thematic analyses. Results: Exercise was students’ most preferred stress reduction activity. Beliefs about exercise emphasized physical benefits yet also not having time for exercise. Beliefs about help-seeking for depression emphasized treatment efficacy, support from others, stigma, and time constraints. Conclusions: Whereas beliefs about positive outcomes inform educational and motivational messages, beliefs about time constraints underscore the need to also consider structural factors that can help students find time to attend to their well-being.

试析利他行为的不同类型及其原因

利他行为可区分为软利他行为和硬利他行为.软利他行为可以用人的利己心解释,而硬利他行为则否.硬利他行为又可以分为有限硬利他行为和无限硬利他行为,有限硬利他行为服从边际效用递减率,而无限硬利他行为则否.无限硬利他行为的形成与进化无法单纯用个体之间的竞争来解释,它是人类在个体之间和群体之间多个层次的竞争当中的适应性行为,是在多层竞争中形成与进化的,是多层竞争选择的结果.
