城乡医疗保险统筹如何影响农村老年人的幸福感？——来自CHARLS数据的证据

基于2011—2018年CHARLS四期面板数据,运用多期双重差分和倾向得分匹配双重差分模型,检验了城乡医疗保险统筹对农村老年人幸福感的影响并探究了其影响机制。结果显示：城乡医疗保险统筹显著提高了农村老年人的积极情感,同时有效降低了其消极情感。机制检验发现,城乡医疗保险统筹通过减轻医疗负担、提高就医便捷性和提升健康预期三条路径影响农村老年人的幸福感。异质性分析表明,该政策对健康状况较差、收入水平较高、东部和中部地区农村老年人幸福感的影响作用更显著。     

基于累积Logistic模型的居民通货膨胀异质性感受的因素研究

通过调查问卷获取居民的通货膨胀感受及相关的个人特征等数据,运用累积 Logistic 模型,从心理层面和外部信息层面考量影响居民通货膨胀感受异质性的因素。结果表明,收入满意程度、食品价格、房租价格以及促销手段等是导致我国居民通胀感受异质性的主要因素。鉴此,政府应该提高收入满意度、稳定物价以及调节房价,以期降低通货膨胀感受的异质性。     

结合像素域JND阈值空间相关性与图像块类型的残差滤波算法

为了更好地将人眼视觉感知特性应用于视频压缩系统,从而去除视频的视觉冗余成分,在利用像素域的恰可察失真(Just Noticeable Distortion,JND)阈值的基础上,结合JND阈值的空间相关性与图像块类型,提出了一种改进的残差滤波算法。该算法首先在像素域计算出每个像素的JND阈值,然后在变换单元(Transform Unit,TU)中挖掘每个像素JND阈值与其周围邻近像素JND阈值之间的空间相关性,再利用索贝儿(Sobel)边缘检测算子将TU分成不同类型的图像块,并且计算出对应的复杂度因子,最后结合上述像素JND阈值的空间相关性和TU复杂度因子对TU残差进行滤波。提出的算法模型可以嵌入到高效率视频编码(High Efficiency Video Coding,HEVC)框架。实验结果表明,在全I帧配置下,提出的算法与标准算法HM16.0相比,在人眼主观感知质量基本一致的情况下,平均可节省16.1%的码率。     

The effects of consumer empowerment on risk perception and satisfaction with food consumption

This study intends to measure consumer empowerment related to food consumption and determine its effect on food risk perception and satisfaction with food consumption. Data were derived from an analysis of the “2017 Research on Food Consumption Behaviour” by the Korea Rural Economic Institute. Consumer empowerment, risk perception and satisfaction with food consumption were measured using a 5‐point Likert scale. The differences in consumer empowerment according to gender, age, educational level and monthly income were statistically significant. The factors that affected risk perception were information use, healthy eating, consumer rights, consumer responsibility and monthly income. The higher the scores for information use, healthy eating and consumer responsibility, the higher the score for satisfaction with food consumption.     

游客感知视角下乡村旅游质效提升维度研究——以西双版纳傣族园为例

发展乡村旅游是实施乡村振兴战略的重要途径，对促进乡村经济发展具有重要作用。以西双版纳傣族园为案例研究地，通过SPSS和AMOS实证探究游客感知视角下乡村旅游质效提升的维度。结果表明：游客感知视角下的乡村旅游质效提升包含旅游地感知、地方认同感、主观幸福感、环境责任行为4个维度；地方认同感和旅游地感知对乡村旅游质效提升的影响力较强，其次是主观幸福感和环境责任行为。     

The bright side of disorganization: When surprise generates low-price signals

The research problem of this paper attempts to understand the effects of disorganized versus organized shelves on search information. Contemporary retail studies have tended to discover how the organization of displays can evoke increased consumer attention. Thus, the purpose is to examine how disorganization cues shelf displays foster surprise through information search and the implications of that process for visualizing low-price signals. In three experiments carried out using eye-tracking devices and face reader techniques (two in the laboratory and one in the field), empirical evidence is presented that disorganization cues can generate an increase in information search generated by cognitive processing, increased emotional surprise manifested levels via schema discrepancy, and perception of low-price provoked by the attempt to reduce the risk of choice.     

Are they telling the truth? Revealing hidden traits of satisfaction with a public bike-sharing service

Public bike-sharing systems (BSSs) are an emerging mode of transportation introduced by municipalities to solve congestion problems in metropolitan areas, especially when integrated with other types of transportation. In the last years, the number of public bike-sharing services has been constantly on the rise all over the world, and generally the overall satisfaction with them is high. However, satisfaction with public services is driven by mechanisms that can differ from those in the private sector. It is important to establish to what extent a high satisfaction is genuine or simply ephemeral. Even “old” public services (like public transportation) become “gold” when accompanied by the introduction of new technologies. In this paper we analyze this phenomenon using data from a satisfaction web-survey conducted among customers of the public BSS “BikeMi” in Milan, Italy, in a period when mobile technologies have been introduced to speed up the service. On analyzing the responses to satisfaction questions using simple summary statistics, the level of satisfaction resulted very high. However, our aim was to look for potential “darker” sides of the service by detecting possible hidden satisfaction components. For this purpose, we used the Nonlinear Principal Components Analysis, which is particularly powerful in this context. A simple textual analysis was also performed as a validating test. Results from our analysis indicated that satisfaction is flawed by a set of factors like the mechanics of the bikes, the picking and dropping system, and the apps used to organize the service. Less concern was detected for more general aspects of the service.     

环境公平感知、社会信任与农户低碳生产行为*——以农膜、秸秆处理为例

［目的］研究旨在探讨环境公平感知和社会信任与农户低碳生产行为之间的关系，为促进农户生产行为向低碳化方向转变提供对策建议。［方法］基于陕西和甘肃两省的村域调查数据，以农膜和秸秆处理为例，运用二元logistic模型探讨环境公平感知和社会信任对农户低碳生产行为的影响，并结合分层回归分析了社会信任在环境公平感知和农户低碳生产行为间的调节效应。［结果］（1）在环境公平感知维度中，人际公平感知正向影响农户的农膜和秸秆处理行为； （2）对社会信任来讲，人际信任对农户农膜和秸秆处理行为均有显著的促进作用，而制度信任仅对农户秸秆处理行为具有正向影响； （3）人际信任在种际公平感知和农户农膜处理行为之间具有显著的正向调节效应，而制度信任在两者之间具有显著的负向调节效应； 同样，人际信任在人际公平感知和农户秸秆处理行为之间具有正向调节效应，而制度信任弱化了人际公平感知对农户秸秆处理行为的影响。［结论］环境公平感知和社会信任是影响农户低碳生产行为的关键因素，且社会信任在种际公平感知和农户农膜处理行为之间以及在人际公平感知和农户秸秆处理行为之间具有显著的调节作用。     

好的表演需要好的观众——顾客察觉准确性在员工情绪劳动影响中的作用

基于385对顾客和员工的问卷调查的配对数据，考察了员工的情绪劳动如何影响顾客的信任和忠诚，以及顾客察觉准确性在其中的调节作用。研究结果表明员工的深层表演会促进顾客的信任，进而促进顾客忠诚；顾客对深层扮演的高察觉准确性会加强员工的深层扮演与顾客信任之间的正向关系，而当顾客对表面扮演察觉准确性低时，员工的表面扮演会对顾客信任有正向的影响；顾客的深层/表面扮演察觉准确性加强了深层/表面扮演、顾客信任和忠诚之间的中介效应。研究帮助从情绪的视角更好地理解服务情境中信任的前因变量，发现顾客的察觉准确性在情绪劳动影响过程中的重要作用，有助于服务企业从情绪劳动的角度来建立顾客信任和忠诚。     

To look tasty,let's show the ingredients! Effects of ingredient images on implicit tasty–healthy associations for packaged products

This study investigates the effect of ingredient images on implicit tasty–healthy associations for packaged products. An implicit association test (IAT) with 106 respondents reveals the impact of repeating ingredient images on the implicit healthy = tasty intuition; fewer ingredient images are linked to a stronger intuition. This study also considers explicit product packaging preferences and the number of ingredient images depicted. The implicit intuitions affect explicit preferences, such that packages depicting few ingredient images are preferred over those depicting many ingredient images for healthy products, but no significant effects emerge for unhealthy products.
