Feedback complexity and corrective efficiency

College undergraduates read a 2400-word passage, responded to 16 multiple-choice questions, and received one of four types of feedback following their responses. Complexity of feedback was inversely related to both error correctability and criterion efficiency taken as a ratio of feedback study time to post-test corrects. The results were discussed in terms of depth of processing and instructional comprehension.     

钱钟书致周采泉书札一通

钱钟书先生腹笥之丰，文笔之美，古今罕匹，其著述中卓荦大者已汇集成册，流布于世。三联版《钱钟书集》，皇皇巨著，凡十种十三册，嘉惠士林，泽被后学，固不待言。然“集”而未“全”，难免为人“求全责备”。如钱先生妙语隽永的书札一概未收，实在让企慕仰止的“钱迷”们感喟遗珠之憾。据说“按照原先的筹划，《钱钟书集》本拟推出书信卷。

在线商品虚假评论形成路径研究

以淘宝为例,通过对43万条评论语料进行分析以及乔装淘宝店主获取的事实数据,从在线商品虚假评论实际解决需要出发,为在线商品虚假评论界定了新的含义,归纳了在线商品虚假评论的影响,最后全面分析了由在线评论者、在线销售商家、在线商品交易平台、虚假评论中介四大主体所组成体系中在线商品虚假评论的六大形成路径、形成动因及特点.本文对下一步的在线商品虚假评论识别技术等相关研究有极强的理论和实践指导意义.     

Polyethylenimine-cyclodextrin-tegafur conjugate shows anti-cancer activity and a potential for gene delivery

Polyethylenimine-cyclodextrin-tegafur (PEI-CyD-tegafur) conjugate was synthesized as a novel multifunctional prodrug of tegafur for co-delivery of chemotherapeutic agent tegafur and enhanced green fluorescent protein (EGFP) reporter plasmid DNA. Conjugation of tegafur to PEI-CyD via chemical linkage was characterized by ¹H NMR spectrometry and ultraviolet (UV) spectrometry. PEI-CyD-tegafur was able to condense plasmid DNA into complexes of around 150 nm with positive charge at the N/P ratio of 25, in accordance with electron microscopy observation of compact and monodisperse nanoparticles. The results of in vitro experiments showed enhanced cytotoxicity and considerable transfection efficiency in B16F10 cell line. Therefore, PEI-CyD-tegafur may have great potential as a co-delivery system with anti-cancer activity and potential for gene delivery.     

Child and Adolescent Predictors of Personality in Early Adulthood

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span.     

Investigating Microadaptation in One-to-One Human Tutoring

The authors investigated whether some advantages of tutoring over other instructional methods are due to microadaptation, or, tutors basing their actions on assessments of tutees they develop during tutoring. In a 2 × 2 between-subjects experiment, independent variables were shared experience (tutors either worked with the same or a different tutee in each of four segment of the tutoring session) and communication context (face-to-face or computer-mediated). Although there were no overall learning differences across experience conditions, tutees who worked with the same tutor demonstrated better learning of concepts initially discussed during the final tutoring segment. Shared experience led to accurate competence assessments only in the computer-mediated context, suggesting that cognitive load influences assessment development. However, there was no evidence of micro-adaptation.
