Sharing economy promotes morality,not impedes it

Sharing economy (SE) is a rapidly growing economic model which has brought people efficiency and convenience; however, it also provides users the opportunity to misbehave, which has raised public concerns about the moral crisis that it might cause. We examined the effect of SE on individuals’ unethical behaviors through four studies. We found consistently that making people believe that they were using shared goods (Study 1) or priming them with abstract SE mindsets (Studies 2–4) reduced, not facilitated, their subsequent cheating on task performances to gain monetary rewards. Moreover, the effect of SE on cheating was mediated by a sense of connecting to others (Study 4). Thinking of using SE enhanced individuals’ interpersonal closeness, which in turn led to less unethical behavior. However, correlational analyses in Studies 3 and 4 showed that people who cheated more in studies in the laboratory also reported using SE more frequently in real life. Implications of these findings are discussed.     

孔颖达的易学诠释学

孔颖达编撰的《周易正义》是唐代易学诠释学的代表作。孔疏从王弼易学基本原则出发 ,吸纳了汉易象数学方法 ,以其取象与取义相结合的鲜明特色 ,对《周易》的体例、八卦和六十四卦的形成 ,对《周易》所蕴涵的原理 ,作出了自己独特的理解与解释。孔颖达的易学诠释学深刻影响了唐宋时期易学和哲学的发展 ,成为汉易向宋易过渡的桥梁。     

马克思对"本体思维方式"的历史性变革

传统本论在黑格尔哲学中达到了它的最高形态,同时暴露出严重问题。对此,马克思没有采取与他同时代的其他哲学家（如叔本华、尼采等）仅仅改变“本体论哲学”的某种理论形态的做法,而是从根本上否定了传统本体论借以立立论的那种“绝对化”的基本思想原则和思维方式,使哲学找回了具有双重生命本性的现实的人和由人参与开拓的现实生活世界。即使如此,也不宜把马克思的哲学归结为“实践本体论”。     

世界大学排名比较中的再认启发式和线索推断

针对三种世界大学排名比较任务(综合实力、商业与管理专业、农业与林业专业),用问卷调查了208名大学生并考察其利用再认启发式和额外线索作推断的情况。结果发现:(1)被试在前两种任务中的正确率均超过60%,选择可再认学校的比率及其正确率也较高;(2)比较类别对再认的选择率及其正确率均有显著影响,效应量很大;(3)再认效度较低或无法利用再认时,被试的选择在不同程度上符合外国线索或专长线索的预测;(4)多出一条不利线索时,再认选择率比只有再认线索时有所降低但不低于50%,多出一条有利线索时,再认选择率的变化因线索而异,不一定显著地增加。     

A Polytomous Model of Cognitive Diagnostic Assessment for Graded Data

Pursuing the line of the difference models in IRT (Thissen &; Steinberg, 1986 Thissen, D., &; Steinberg, L. (1986). A taxonomy of item response models. Psychometrika, 51:567–577. doi:10.1007/BF02295596.[Crossref], [Web of Science ®] , [Google Scholar]), this article proposed a new cognitive diagnostic model for graded/polytomous data based on the deterministic input, noisy, and gate (Haertel, 1989 Haertel, E. H. (1989). Using restricted latent class models to map the skill structure of achievement items. Journal of Educational Measurement, 26, 333–352. doi:10.1111/j.1745-3984.1989.tb00336.x.[Crossref], [Web of Science ®] , [Google Scholar]; Junker &; Sijtsma, 2001 Junker, B. W., &; Sijtsma, K. (2001). Cognitive assessment models with few assumptions, and connections with nonparametric item response theory. Applied Psychological Measurement, 25, 258–272. doi:10.1177/01466210122032064.[Crossref], [Web of Science ®] , [Google Scholar]), which is named the DINA model for graded data (DINA-GD). We investigated the performance of a full Bayesian estimation of the proposed model. In the simulation, the classification accuracy and item recovery for the DINA-GD model were investigated. The results indicated that the proposed model had acceptable examinees' correct attribute classification rate and item parameter recovery. In addition, a real-data example was used to illustrate the application of this new model with the graded data or polytomously scored items.     

Proportional Reasoning in 5- to 6-Year-Olds

There have been mixed results in studies investigating proportional reasoning in young children. The current study aimed to examine whether providing visual scaling cues and structuring the reasoning process can improve proportional reasoning in 5- to 6-year-old children. In a series of computerized tasks, children compared the sweetness of 2 mixtures. Each mixture was represented by a juice rectangle stacked on top of a water rectangle. Two rectangles shared the same width but were of same or different heights. The mixtures were scaled by either changing their widths or their heights. In Experiment 1, children’s performance was poor when judging equivalent proportions. In Experiment 2, the 2 mixtures were individually previewed to encourage individual estimation of each mixture and thereby allow participants to strategically reason about the relative proportions. Children performed significantly better than in Experiment 1. In Experiment 3, children explicitly rated the sweetness of each preview mixture. Performance did not improve relative to Experiment 2. Throughout all 3 experiments, children were more sensitive in detecting equivalence when scaling occurred along the width compared with the height, demonstrating the effectiveness of visual-spatial scaling cues. Together, these experiments suggested that visuospatial scaling cues and structuring the 2-step reasoning process using previews can improve 5- to 6-year-olds’ proportional reasoning with certain limitations.     

Use of Photovoice in Processing Race-Based Topics in a Multicultural Counseling Course

This phenomenological study assessed master-level students’ experiences of using photovoice, a creative learning activity, in a race-based multicultural counseling course. Students were asked to engage in weekly written reflections regarding a course-related photographic image, with the goal of more deeply processing cognitive and affective reactions to the course. Data analyzed included focus groups, student written responses, and photos. Findings indicated use of photovoice as a means for processing cognitions, which allowed students to deepen learning by extending a racialized lens outside of the classroom. Students also indicated use of the tool to process emotional reactions at various stages of the course, allowing learners to creatively and visually express feelings as they surfaced.     

Using a Kinect sensor to acquire biological motion: Toolbox and evaluation

Biological motion (BM) is the movement of animate entities, which conveys rich social information. To obtain pure BM, researchers nowadays predominantly use point-light displays (PLDs), which depict BM through a set of light points (e.g., 12 points) placed at distinct joints of a moving human body. Most prevalent BM stimuli are created by state-of-the-art motion capture systems. Although these stimuli are highly precise, the motion capture system is expensive and bulky, and its process of constructing a PLD-based BM is time-consuming and complex. These factors impede the investigation of BM mechanisms. In this study, we propose a free Kinect-based biological motion capture (KBC) toolbox based on the Kinect Sensor 2.0 in C++. The KBC toolbox aims to help researchers acquire PLD-based BM in an easy, low-cost, and user-friendly way. We conducted three experiments to examine whether KBC-generated BM can genuinely reflect the processing characteristics of BM: (1)?Is BM from this source processed globally in vision? (2)?Does its BM (e.g., from the feet) retain detailed local information? and (3)?Does the BM convey emotional information? We obtained positive results in response to all three questions. Therefore, we think that the KBC toolbox can be useful in generating BM for future research.     

Physical pain induces negative person perception

We examined the hypothesis that pain increases negative person perception of irrelevant others in both medical and laboratory settings in three studies. Patients perceived a nurse as more negative if the injection they received from the nurse produced more pain (Pilot Study). Patients rated neutral faces as more negative after receiving an injection than before it (Study 1). Participants who performed a painful cold pressor task rated neutral faces as more negative than a control group, but this effect only appeared for those with low perceived social support (Study 2). These findings suggest that one's experience of physical pain may be metaphorically transferred to perceptions of completely irrelevant others, inducing negative interpersonal perception. And perceived social support can ameliorate the negative effect.
