论“主体建构”的认识论来源及理论意义

本文着力解决的是主体建构在社会科学诸多范式与取向中的合法性问题。主体建构是一种视角、一个解释工具,也是一种方法论取向,同时也可以被理解为一种认识论倾向。主体建构以现象学关于主体意向性与意义建构的论断为认识论基础,以理解社会学为理论源泉,试图理解关于同一社会现象在不同主体的视角下的不同的意义。主体建构的目的是对这些不同的意义进行差异性理解、过程性理解与情境性理解,并以此解构垄断意义与固化意义,寻求社会现象的多元意义。     

基于消费者效用的生鲜农产品供应链生鲜度激励机制研究

生鲜供应链整体生鲜度的提升对减少浪费、提高供应链整体盈利水平及社会福利有重要意义。本文基于消费者效用理论研究了两供应商和单一零售商组成的供应链系统，构建了单周期下生鲜农产品生鲜度激励模型，模型以供应商为领导者，采用Stackelberg博弈方法求解得到了均衡状态下供应商、零售商的最优定价策略及供应商新鲜度努力选择。研究结果表明，供应商和零售商利润与消费者价格敏感系数呈反向变化，与新鲜度敏感系数呈同向变化。在价格竞争市场，供应商保鲜努力程度和利润与价格替代率呈反向变化；在生鲜度竞争市场，供应商保鲜努力程度和利润与新鲜度替代率呈同向变化。基于研究结论，厂商及政府应当联手引导消费者的消费观念，尽可能减少由于信息不对称引致的道德风险，在市场价格替代率不变甚至降低的情形下，提高生鲜度替代率，使得消费者的意愿支付价格上升，提高自身讨价还价能力，获取更多利润。     

Relational Management Mechanisms for Strategic Alliances Among Nonprofit Organizations

This study employs a qualitative multiple-case study to explore relational management mechanisms for strategic nonprofit alliances (NPAs) formed by at least 3 nonprofit organizations by examining collaborative relationships among farmers associations in Taiwan. We explore these mechanisms by analyzing case data from four strategic cooperation characteristics, which can best explain NPAs. To effectively sustain partnerships, our findings suggest that an NPA applies acceptable collaborative rules and regulations, common standard procedures, symmetric information and communication, and capability building and corrective measures when cooperation involves high input commonality. The results also suggest empowerment for partners with deeper input commitment to direct decisions on resource distribution and utilization when collaborative ties involve low input measurability. Regarding high output commonality, we advise NPAs to enforce common output quality control, efficient substandard-output treatment, and external incentives as mechanisms to encourage partners for continued commitment. If relationships involve low output measurability, our findings suggest that NPAs heighten partners’ voluntary motivation for the common good, with goal-achievement assessment measures, professional certification by external experts, and acceptable and reasonable benefit-sharing methods     

论新媒体冲击下纸媒的生存与发展——以报纸为例

互联网的发展、智能手机的普及使传统的传媒环境和格局发生了翻天覆地的变化。新媒体的崛起与壮大给以纸媒为代表的传统媒体带来了前所未有的冲击，但不可否认的是，纸媒自身依然有不可替代的优势。本文主要以报纸为例，从纸媒传播内容的深度和可信度、纸媒对于受众文化素质的要求以及纸媒的表现形式、和受众的互动等方面的特点入手，分析在新媒体的冲击下纸媒所面临的生存现状，并且在此基础上指出将来纸媒应该如何利用新媒体的技术来促进自身的发展，更好地实现新媒体与传统媒体的融合。     

PROVIDING GLOBAL PUBLIC GOODS: ELECTORAL DELEGATION AND COOPERATION

This study experimentally examines the effect of electoral delegation on providing global public goods shared by several groups. Each group elects one delegate who can freely decide on each group member's contribution to the global public goods. Our results show that people mostly vote for delegates who assign equal contributions for every group member. However, in contrast to standard theoretical predictions for our delegation mechanism, unequal contributions across groups drive cooperation down over time, and it decreases efficiency by almost 50% compared to the selfish benchmark. This pattern is not driven by delegates trying to exploit their fellow group members, as indicated by theory. It is driven by conditional cooperation of delegates across groups. Since one of the potential sources of the resulting inefficiency is the polycentric nature of global public goods provision together with other‐regarding preferences, we use the term P‐inefficiency to describe our finding.

我国幼儿食育必要性及其促进策略

食育是饮食行为教育，是对孩子进行包括饮食观念、膳食营养知识和饮食卫生安全等一系列营养学的教育。食育的开展是一项利国利民，值得大力推广的事情。食育应当成为全民的教育，且越早开始越好。目前我国食育还处于萌芽阶段，幼儿食育的推进更是任重而道远，需要幼儿园、家庭、政府、社区乃至全社会的共同参与。     

Conditional Akaike Information Criteria for a Class of Poisson Mixture Models with Random Effects

Focusing on the model selection problems in the family of Poisson mixture models (including the Poisson mixture regression model with random effects and zero‐inflated Poisson regression model with random effects), the current paper derives two conditional Akaike information criteria. The criteria are the unbiased estimators of the conditional Akaike information based on the conditional log‐likelihood and the conditional Akaike information based on the joint log‐likelihood, respectively. The derivation is free from the specific parametric assumptions about the conditional mean of the true data‐generating model and applies to different types of estimation methods. Additionally, the derivation is not based on the asymptotic argument. Simulations show that the proposed criteria have promising estimation accuracy. In addition, it is found that the criterion based on the conditional log‐likelihood demonstrates good model selection performance under different scenarios. Two sets of real data are used to illustrate the proposed method.     

创新理念的中国管理C模式解读

"创新"发展理念的践行与中国传统文化密切相关。中国古典哲学从儒、墨、道、法、兵、易、禅等学说为创新提供了"仁义"的价值内核、创新主体自由发展的驱动力、"德性管理、实践理性"的方法论、尚贤尚同的组织原则、"权变、逆向、谋算、质疑、直觉、发散、非线性"等创新思维、"博学、审问、慎思、明辨、笃行"的创新过程管理、"知行合一"的创新实践机制,"超越"的本质精神,以"整体性""导向性""动态性"的文化管理体系推动创新的生生不息。进一步整合西方创新理论与管理工具,则构建了中国管理C模式的创新管理系统模型。阴阳变易法则推动创新元素的融合转化与裂变,形成开放式、协同式的"有机组织",推动全面创新及自主创新。中国管理C模式实现了创新管理的价值性、工具性、实践性的统一,为大众创新提供了管理哲学视角的理论基础与方法论。     

巨变与定型:经济地理格局中的城市能级与层级态势研究

当前,中国城市经济地理格局正处于前所未有的巨变中。这种巨变体现在两个层面:一是城市的能级不断跃升,二是城市的层级基本定型。能级跃升与层级定型的矛盾,是当代中国城市经济地理格局中的客观现实。这意味着,对于雄心勃勃的强二线城市来说,能级继续跃升的空间依然很大,但想在层级上与一线城市比肩,几无可能。故,对强二线城市来说,更好的选择是尊重近40年改革开放所形成的城市层级秩序,把方向与精力放在提升城市能级上。
