This study investigates choice-based learning as a choice between lecture-based or team learning in a large class at a large university in a European country. The study was designed as a between-subjects quasi-experiment where students were allocated their preferred learning approach. Data were collected for eight consecutive years (2008–2016). Based on quantitative and qualitative data, this study investigates the effect of choice-based learning on choice satisfaction, student selection and on student learning outcomes. The results show that team learning has a positive effect on learning outcomes. If students are faced with the choice, the majority select lecture-based learning. Additionally, both student groups are satisfied with their selected learning paths but selected them for specific reasons. Finally, choice-based learning provides job satisfaction for the instructors of both learning paths. These results can re-energize the ongoing discussion on why and how to engage students in learning activities.  相似文献

In recent years, labor-intensive agricultural products from developing countries have exhibited inferior performance in international trade due to quality and safety incidents, among which pesticide residue is a major issue. Aiming to improve food quality and safety in the context of cooperatives, we introduced three categories of control measures: outcome control, process control and social control. Based on the Pre-Harvest Interval Standard (PHIS), we selected three indices, farmers’ implementation rate of PHIS, absolute distance to PHIS and relative distance to PHIS, to evaluate appropriateness of pesticides use, reduction of pesticide residue and safety improvements of agricultural products. By using random sampling survey data, we empirically analyzed the marginal effects of control measures and their combinations on food quality and safety standards. The empirical results show that implementing process control, namely, unified production standards or supply of unified agricultural inputs, can comprehensively improve farmers’ implementation rate of PHIS, absolute distance and relative distance to PHIS respectively by 34.9%, 3.2 days and 46.0% on average. While the effects of outcome control (safety inspection) and social control (bonus-penalty incentive or training) are restricted to other measures. Therefore, we suggest cooperatives should take farmers’ features, implementation conditions and the effects of control measures into consideration in order to make a sustainable management plan for improving food quality and safety and enhancing competitiveness in international markets.  相似文献

合理地衡量和评价省联社对农信社效率的影响,是推动省联社改革的基础,也是当前理论和实践中面临的难题。本文在对省联社的管理服务职能详细调查的基础上,提出了通过比对省联社管理导向和农信社效率提升方向之间的差异,间接分析省联社管理对农信社效率的影响,并以2010-2017年A省75家农信社为研究对象进行了实证分析。研究结果表明,当前省联社管理的总体导向是:有效引导农信社在扩大业务规模的同时,控制总成本收入比和降低不良贷款水平,但对农信社的利润水平、风险覆盖水平、支农支小情况缺乏实质性约束;在推动农信社改制为农商行的过程中缺乏对其提高经营效率的帮助,在管理中未充分考虑各家农信社及其所处市场环境的差异等。文章建议,当前省联社改革的路径是“减少管理+增强服务”,其中减少管理的关键是解决退出职责谁接管的问题,而增强服务的关键是对省联社进行更有效的激励约束。  相似文献

以资源基础理论、交易成本理论为基础,探讨了开放环境下企业不同合作研发模式对创新绩效的影响,以及知识和技术的中介作用与内部研发的调节作用。基于2014-2016年816家河北省高新技术企业数据的长短期对照检验结果表明:不同合作研发模式对创新绩效有不同影响,且无论长短期,境外合作的影响最强,产学、产政合作长期效应强,产研合作短期效应强;知识和技术起部分中介作用,内部研发正向调节产学、产政合作绩效,负向调节产研、境外合作绩效。研究结论对于高新技术企业选择研发战略具有重要意义。  相似文献

Cooperatives are established to improve farmers' production conditions, to increase their bargaining power and to enable them to benefit from modern value chains. In China, farmers are members of a cooperative for multiple reasons. Little is known on whether and how cooperative membership affects farmers’ choice of marketing channels. This paper examines determinants of farmers’ choice of marketing channels, especially how cooperative membership impacts upon this choice. Our analysis is based on survey data collected in 2015 among 625 apple growing farm households in the provinces Shaanxi and Shandong. We employ endogenous switching probit models to deal with potential endogeneity of membership in estimating the determinants of marketing channel choices. We find that cooperative membership has a positive impact on selling to wholesalers and a negative impact on selling to small dealers, but no significant impact on selling to the cooperative itself. As products sold through cooperatives generally comply with relatively stringent food quality and safety standards, these results imply that policies promoting cooperative members to sell their products through cooperatives are likely to have a significant impact on food quality and food safety in China.  相似文献

将企业研发模式分为自主研发、合作研发和双重研发三种,使用世界银行对中国制造业企业的调查数据,通过倾向得分匹配方法探究不同研发模式对企业创新绩效的作用效果及其在异质性企业中的差异情况。全样本研究结果表明:企业双重研发对创新绩效的激励效果最好,合作研发的激励效果次之,自主研发的激励效果最弱。企业异质性研究结果显示:自主研发对高成长性企业创新绩效的激励效果最显著,合作研发对低成长性企业和小微企业的激励效果最显著;对于无融资约束的企业,双重研发模式是提升创新绩效的最佳选择,但是对有融资约束的企业,其提升效果最弱。  相似文献

We study a non-traditional cooperative game where returns from coalitions are nondeterministic. The long-standing concept of core can be generalized to reflect players’ contentment with their allocations. It is now imperative to formalize the restrictions, such as those pertaining to information, on allocations. The latter are also at times more conducive to fractional representations. With probabilistic structures added, nondeterministic returns become random variables, utility functions attain risk-attitude connotations, and the timing of players’ allocation resolutions gains significance. Under various conditions for utility functions, we show how various core concepts of the general game can be related to its traditionally defined auxiliaries. These developments help pave the way for our illustrations, within two distinct settings, that players’ increased risk aversion would promote the formation of the grand coalition.  相似文献

农民合作社联合社是一种典型的社会经济组织现象。目前,国外经验难以有效解释中国语境下联合社的实践逻辑,国内研究也相对缺乏系统性理论解释。本文在一种关于组织行为的新分析框架(SAGP模型:性状-行动者-治理-绩效)的基础上,结合台联九生猪专业合作社联合社的个案研究,对联合社的形成和发展进行系统性理论解释。本文指出联合社形成和发展背后的功能逻辑在于生产规模化、业务产业链化和发展创新化,运行逻辑在于基础业务合作化机制、投资业务市场化机制和政府关系合法化机制。  相似文献

在知识经济时代,知识是企业发展和创新的源泉与重要资源。研发团队沟通行为是影响高新技术企业自主创新绩效的重要因素,探究其对自主创新绩效的影响机制具有重要意义。以社会认同、知识共享等理论为基础,以知识吸收能力为中介变量,分析高新技术企业研发团队沟通行为与自主创新绩效的关系,运用逐步回归分析法对288份有效样本进行实证分析。研究发现:研发团队合作性沟通对团队产品创新绩效和工艺创新绩效有正向影响;研发团队竞争性沟通和回避性沟通对团队产品创新绩效和工艺创新绩效有负向影响;知识吸收能力在研发团队合作性沟通、竞争性沟通与自主创新绩效的影响中起显著中介作用,但是在研发团队回避性沟通对自主创新绩效影响的中介作用不显著。结论为提升高新技术企业研发团队自主创新绩效提供了新的方法与路径,对企业提高知识共享与创新能力,开展创新活动具有重要启示。  相似文献

This study discusses how a green retailer's fairness concerns affect product greenness and profit and explores how to distribute surplus profits under the fairness concerns using cooperative game theory. Research findings indicate that cooperation contributes to increasing channel profits and improving product greenness, but the fairness concerns are detrimental to them. The three proposed coordination mechanisms (SVM, NSM, and TVM) are feasible to ensure coalition stability, but their beneficiaries differ. NSM benefits a manufacturer, while SVM benefits retailers. Additionally, the green retailer's fairness concerns serve as distribution tools to narrow profit gaps between the manufacturer and the green retailer.  相似文献
