产品销量和推荐数对网络消费决策的影响:价格的调节效应

基于目标感染理论,探究了产品销量和产品推荐数对大学生网络消费决策的影响,并进一步探究了产品价格在大学生网络消费决策中的调节作用。两项研究均表明,产品销量和推荐数均会促进大学生做出消费决策。其中,产品价格调节了两者对网络消费决策的影响,具体表现为在选购低价格产品时,大学生更加看重产品销量,倾向选购高销量产品;而在选购中高价格产品时,大学生更加看重产品推荐数,选购高推荐数的产品。本研究为网络电商平台如何针对不同价位产品制定产品展示方案提供了理论支持和实践指导。     

触觉刺激对触觉注意启动作用的研究

目的：探讨触觉刺激对触觉注意的影响,以揭示选择性注意的机制。方法：利用在体电生理记录技术,记录了288个丘脑腹侧基底核（ventrobasal nuleus of thalamus,VB）神经元放电活动,并着重考察了不同强度触觉刺激对丘脑神经元细胞自发放电活动的影响。结果发现：触觉刺激对大部分的触觉神经元的自发放电活动均有抑制性影响。提示触觉刺激降低背景噪声可能是触发选择性触觉注意的神经机制。     

麻姑考辨

麻姑是道教著名的女仙,现可考的关于麻姑的最早记载见于《列异传》蔡经条,而麻姑形象的确立是在葛洪的《神仙传》中,后代关于麻姑的记载多源于《神仙传》。麻姑原型应当是远古流传于中国东方或南方的一个女仙。麻姑与南城麻姑山关系的确立是在唐玄宗时期。此后,麻姑山及其传说才开始名扬天下。     

教师组织公民行为与教学效能感的关系研究

文章采用教师组织公民行为与教师教学效能感问卷,对广州市的205名初中教师进行了研究,以探讨学校等级、性别、职称、学历、教龄等背景变量对初中教师组织公民行为、教学效能感的影响,以及教师组织公民行为与教师教学效能感之间的关系。结果发现:教师组织公民行为、教学效能感在学校等级和职称上存在着显著性差异;教师组织公民行为与教师教学效能感之间存在着显著性相关,教师组织公民行为中的认同组织和良心行为因子是教师教学效能感的有效预测变量。     

A critique to the significance of Gettier counter-examples

Usually, people think that Gettier counter-examples challenged the traditional tripartite definition of knowledge and fundamentally changed the characteristic of the contemporary epistemology. This paper argues that regard for Gettier counter-examples is exaggerated, because (i) the JTB definition is neither an important nor a comprehensive one that covers all knowledge. Moreover, the significance of Gettier counter-examples is limited. (ii) The source of Gettier counter-examples lies in one arbitrary judgment, two mix-ups, three false assumptions, and a misunderstanding about the JTB definition. __________ Translated from Fudan Xuebao 复旦学报 (Fudan Journal), 2004 (5)     

大学生的自我构念与动机定向关系研究

该研究采用自我构念(SCS)量表和工作(学习)动机定向量表对432名大学生进行调查,探讨了中国大学生自我构念与动机定向的关系。结果表明:1)大学生自我构念与动机定向各维度有密切相关;典型相关发现自我构念各维度通过三个典型因素解释动机定向变异的13.2%;2)不同自我构念类型大学生的动机定向存在显著差异,二元型自我构念大学生的总体动机水平最高,边缘型自我构念大学生的总体动机水平最低;独立型自我构念大学生的关注人际竞争和追求回报动机水平显著高于依赖型自我构念大学生,而选择简单任务及关注他人评价动机水平显著低于依赖型自我构念大学生。     

A receiver operator characteristics analysis of treatment outcome in binge eating disorder to identify patterns of rapid response

The purpose of this study was to perform a receiver operator characteristics (ROC) analysis on a treatment sample from a randomized controlled treatment trial of participants with binge eating disorder (BED). An ROC analysis was completed with 179 adults in a 20-week treatment trial for BED to predict abstinence from binge eating at end of treatment. Percent reductions in binge eating episodes were examined following weeks 1 through 10 of treatment. The rate of percent decrease in binge eating episodes during treatment for BED was a significant predictor of clinical outcome at end of treatment. Participants who demonstrated a 15% reduction in binge eating episodes at week one were more likely to respond positively to treatment and achieve clinical remission. Findings from the current study suggest that a significant reduction in binge eating during the first week of treatment may be predictive of end of treatment remission in those with BED.     

Selecting polychoric instrumental variables in confirmatory factor analysis: An alternative specification test and effects of instrumental variables

The polychoric instrumental variable (PIV) approach is a recently proposed method to fit a confirmatory factor analysis model with ordinal data. In this paper, we first examine the small-sample properties of the specification tests for testing the validity of instrumental variables (IVs). Second, we investigate the effects of using different numbers of IVs. Our results show that specification tests derived for continuous data are extremely oversized at all sample sizes when applied to ordinal variables. Possible modifications for ordinal data are proposed in the present study. Simulation results show that the modified specification tests with all available IVs are able to detect model misspecification. In terms of estimation accuracy, the PIV approach where the IVs outnumber the endogenous variables by one produces a lower bias but a higher variation than the PIV approach with more IVs for correctly specified factor loadings at small samples.     

Effect of individual thinking styles on item selection during study time allocation

The influence of individual differences on learners' study time allocation has been emphasised in recent studies; however, little is known about the role of individual thinking styles (analytical versus intuitive). In the present study, we explored the influence of individual thinking styles on learners' application of agenda‐based and habitual processes when selecting the first item during a study‐time allocation task. A 3‐item cognitive reflection test (CRT) was used to determine individuals' degree of cognitive reliance on intuitive versus analytical cognitive processing. Significant correlations between CRT scores and the choices of first item selection were observed in both Experiment 1a (study time was 5 seconds per triplet) and Experiment 1b (study time was 20 seconds per triplet). Furthermore, analytical decision makers constructed a value‐based agenda (prioritised high‐reward items), whereas intuitive decision makers relied more upon habitual responding (selected items from the leftmost of the array). The findings of Experiment 1a were replicated in Experiment 2 notwithstanding ruling out the possible effects from individual intelligence and working memory capacity. Overall, the individual thinking style plays an important role on learners' study time allocation and the predictive ability of CRT is reliable in learners' item selection strategy.
