“互联网+医疗健康”背景下考虑患者反馈机制的药品质量监管策略研究

药品质量关乎公众生命健康、国民经济发展、社会稳定和国家安全，一直以来都是政府和全社会关注的热点问题之一。"互联网+医疗健康"背景下药品流通速度加快使得药品安全问题影响范围扩大，因此，建立患者反馈机制是促进互联网药品质量监管的有效方式。考虑患者反馈机制下如何设计互联网药品质量监管策略的问题，基于演化博弈理论，构建了政府部门、药品生产商、医药电商和患者参与的药品质量监管四方演化博弈模型，通过分析各博弈主体策略选择的稳定性，并基于Lyapunov第一法则对复制动态系统十六种均衡点进行稳定性分析，研究了促进药品生产商提供高质量药品的政府监管策略和患者反馈机制，并利用Matlab 2017仿真分析了各关键要素对策略演化的影响。研究结果表明：1）患者倾向于失真评价或投诉率较低时，医药电商更倾向于选择药品质量不检测，不利于互联网药品质量安全；2）患者失真评价下，不存在药品生产商提供高质量药品的稳定策略组合，而真实评价下有效的反馈机制和监管机制可使互联网药品质量安全具有稳定性；3）提高患者评价（正面评价或负面评价）带给医药电商和药品生产商的声誉价值增加或声誉损失，将会使药品生产商选择提供高质量药品做为稳定策略；4）降低患者失真评价和投诉维权行为的增加，均可增强药品生产商提供高质量药品的稳健性。最后，结合演化博弈模型和仿真分析结果，为完善药品质量监管机制提出了对策与建议。     

Feedback-conditional regret theory and testing regret-aversion in risky choice

Regret is an aversive emotion experienced upon the discovery that, had a different choice been made, a higher level of utility would have obtained than actually did. Because regret can be anticipated prior to choice it can lead to regret-minimising decisions. It has been shown that the experience of post-decisional regret is generally dependent on discovering the outcome of foregone acts as well as chosen acts. The most popular version of regret theory does not include an explicit account of the impact of foregone act resolution on anticipated regret-aversion as a decision motive. This restricts its domain of applicability. This paper modifies regret theory to accommodate the impact of outcome feedback on anticipated regret-aversion. The theoretical and empirical implications of this new version of regret theory are discussed.

档案利用反馈信息处理工作是档案管理系统中的一个重要环节.通过对反馈信息的分析研究,可以发现档案管理系统中存在的问题,从而从总体上促进档案工作的发展.然而,当前不少单位对档案利用反馈信息处理工作并未给予充分的重视,直接影响了这项工作的发展.     

从系统动力学角度研究海洋的可持续发展

海洋资源与环境、经济和社会3个要素构成一个动态系统,这个系统以海洋资源为物质基础,以经济生产推动系统的演变发展,而系统的进化则表现为社会的进步,系统内部存在各种信息反馈。海洋可持续发展所面临的就是如何协调海洋资源与环境、社会和经济3者之间关系的问题。在分析了该系统的动态性和反馈机制的基础上,提出从系统动力学角度来研究海洋的可持续发展,并对其科学性和优越性做出论证和说明。     

单变量反馈实现混沌同步

本文对两个耦合的Lorenz系统进行了数值研究，结果表明，用单变量反馈可实现混沌同步，这种同步具有较快的收敛速率和较高的稳定性．和T．L．Caroll，L．M．Pecora的混沌同步法一样，反馈法同步的混沌系统也可以用于秘密通讯，并且结构简单，便于应用．     

小学英语课堂会话中的语言错误、纠正反馈语和修正后的可理解输出

本文利用10节课堂会话语料探讨了小学课堂会话中学生语言错误、教师纠正反馈语和学生修正后的可理解输出之间的关系。数据表明,优秀教师针对学生语言错误而选用的纠正反馈语是有规律的,他们倾向针对学生的语法错误使用明确纠正法,针对词汇、语音错误使用形式协商法。这种针对性能推动学生产生修正后的可理解输出。

The Impact of Authority Relations and Feedback Delivery Method on Performance

ABSTRACT

The proliferation of technology has been changing feedback delivery methods in organizations. However, the effectiveness of feedback delivery methods can vary depending on social dynamics (e.g., authority relations) in the organization. The current study was designed to examine the impact of authority relations and feedback delivery methods on performance. A total of 120 participants were recruited to work on a simulated cell-phone assembly task and were exposed to one of the four feedback conditions: (a) authority figure with face-to-face feedback, (b) authority figure with e-mail feedback, (c) non-authority figure with face-to-face feedback, and (d) non-authority figure with e-mail feedback. Results showed that while both feedback delivery methods resulted in high performance with the presence of an authority figure, only face-to-face feedback resulted in high performance with a non-authority figure. Practical considerations for effective feedback delivery methods in relation to authority figures are also discussed.     

Enhancing Self‐Protective Behavior: Efficacy Beliefs and Peer Feedback in Risk Communication

In times of a high‐impact safety incident citizens may have a variety of sources available to help them cope with the situation. This research focuses on the interplay of efficacy information in risk communication messages and peer feedback, such as responses on social network sites (SNSs) in the context of a high‐impact risk on the intention to engage in self‐protective behavior. The study pitted high and low efficacy information messages against supporting and opposing peer feedback (N = 242). Results show a significant interaction effect between efficacy information in a news article and peer feedback from SNS messages on both the intention to engage in self‐protective behavior and levels of involvement. Participants who received the article with more efficacy information and also received supportive peer feedback via SNS messages were more likely to express higher levels of involvement and greater intentions to engage in protective behavior. When confronted with a low efficacious news article, the effect of peer feedback on these two variables was significantly stronger. Finally, implications for theory and government risk communication are discussed.
