The absence of a market mechanism based on trust among suppliers and customers is to blame, although other factors as well holding the responsibility. Beginning with an introduction to the theory of ＂lemons＂, this paper reviews the status quo of trust in the Chinese cyber market, from the perspective of legislation, regulation and institution. It also prescribes several possible micro-solutions.展开更多

Firstly, the multilevel elitist roles based dynamics equilibrium strategy is established, and both immigration and emigration of elitists are able to be self-adaptive to balance between exploration and exploitation for feature selection. Secondly, the utility matrix of trust margins is introduced to the model of multilevel elitist roles to enhance various elitist roles＇ performance of searching the optimal feature subsets, and the win-win utility solutions for feature selec- tion can be attained. Meanwhile, a novel ensemble quantum game strategy is designed as an intriguing exhibiting structure to perfect the dynamics equilibrium of multilevel elitist roles. Finally, the en- semble manner of multilevel elitist roles is employed to achieve the global minimal feature subset, which will greatly improve the fea- sibility and effectiveness. Experiment results show the proposed EERQG algorithm has superiority compared to the existing feature selection algorithms.展开更多
目的:了解抑郁患者的依恋关系和人际信任现状,探究人际信任在依恋关系和抑郁间的中介作用。方法:收集2019年10月至2022年3月就诊于上海市精神卫生中心咨询门诊抑郁患者(抑郁组)149例,同期招募健康对照组114名。采用亲密关系体验问卷修订...目的:了解抑郁患者的依恋关系和人际信任现状,探究人际信任在依恋关系和抑郁间的中介作用。方法:收集2019年10月至2022年3月就诊于上海市精神卫生中心咨询门诊抑郁患者(抑郁组)149例,同期招募健康对照组114名。采用亲密关系体验问卷修订版(experiences in close relationship-revised, ECR-R)、信任量表(trust scale)、信任游戏(trust game)分别测量依恋关系、人际信任态度和人际信任行为,使用汉密尔顿抑郁(Hamilton depression scale, HAMD-17)评估抑郁症状。结果:抑郁组的信任量表、信任投资游戏评分均低于对照组(P均<0.05),依恋焦虑和依恋回避评分均高于健康对照组(P均<0.001)。Pearson相关分析显示,依恋关系、信任问卷和信任投资游戏评分均与抑郁分数存在显著相关(P均<0.05)。依恋关系通过人际信任态度和行为预测抑郁的间接效应分别为0.112和0.032,分别占总效应的20.14%和5.76%。结论:依恋关系可直接或间接预测抑郁,人际信任态度和行为在依恋关系和抑郁间起部分中介作用。展开更多
