幼儿情绪认知能力发展特点的研究

本研究采用面部表情辨别和实际情境下的情绪认知两种实验任务测查了95名3～5岁幼儿的情绪认知能力。结果表明：（1）幼儿的情绪认知能力存在显著的年龄差异，随着年龄的增长而增长，但每种具体情绪的发展模式不同；（2）幼儿的情绪认知能力不存在显著的性别差异。     

Confirmatory factor analysis of word recognition and process measures in the Colorado Reading Project

Measures of word recognition (REC) and two component skills, phonological coding (PHON) and orthographic coding (ORTH), were subjected to multivariate behavioral genetic analysis. Data were obtained from a sample of identical and fraternal twin pairs wherein at least one member of each pair was reading disabled (RD), and from a sample of twins wherein both members of each pair read in the normal range. Confirmatory factor analysis was used to fit the genetic, common environmental, and specific environmental covariance components for REC, PHON, and ORTH within the RD and normal simples. The resulting heritability estimates for REC, PHON, and ORTH were 0.59, 0.41, and 0.05 in the RD sample, and 0.35, 0.52, and 0.20 in the normal sample. After dropping the nonsignificant common environment parameters from the models, the genetic correlations between REC and PHON and between REC and ORTH were respectively 0.81 and 0.45 in the RD sample, and 0.68 and 0.45 in the normal sample. Differences between the genetic correlations were significant in the RD sample (p<0.005), marginally significant in the normal sample (p<0.10), and highly significant in the combined sample (p<0.001), indicating that genetic influences on individual differences in REC are more strongly related to genetic variance in PHON than in ORTH. These results are consistent with previous demonstrations of substantial genetic covariance between the disabled group's deficits in REC and PHON, but not between REC and ORTH (Olson et al., 1989; Olson and Rack, 1990).

明人自传文论略

本着重探讨明人自传的体类型、写作动机与叙事特征，体类型包括序、状、述、传、记、墓志铭、祭、吊；写作动机可以分为写实与写趣两种倾向；叙事方式，可以分为记叙与问答两种体式；人称有第一人称叙事、第三人称叙事和第二人称叙事。明人自传大都长于描绘生活状况、刻画人物个性和剖析自我灵魂，堪称一幅幅士人自我形象的自画像。     

解构"自由美学",建立"自我美学"

"人本质"不是"自由",故而"自由美学"不足为训,应予解构。"人本质"是"自我",从"自我"出发解释"美本质", 建立"自我美学",也许正构成21世纪中国美学发展的正确方向、必然选择和真正希望所在。     

The interrupted learner: How distractions during live and video lectures influence learning outcomes

New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi‐year study of the first‐year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first‐year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in “non‐lecture activities” (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities—whether live or recorded—can have an important impact on learning outcomes.

对加工贸易渠道走私普通货物犯罪的研究--以东莞市为切入点

作为一个经济运作模式，加工贸易确实给我国，尤其在“珠三角”、“长三角”一些地方的经济带来了极大的利益，但同时也在相当程度上模糊了人们对加工贸易走私危害的严重性的认识。本文描述了东莞市加工贸易渠道走私犯罪的现状、特点，在此基础上，列举、分析了司法、执法中存在的客观困难和人为因素问题，剖析原因并提出了有效打击加工贸易走私行为的建议。
