农民“被上楼”现象的伦理反思

新农村建设过程中农民"被上楼"现象,源于民生时代的伦理缺位.一是伴随承载着传统人文生态的农民居所的变化,缺乏一种与之适应的全新人文伦理生态;二是农民上楼缺乏一种生活体验上的主体性认同;三是农民上楼过程中,缺乏资源性的政治动员与其利益分配的道德支持.

Structure and measurement of depression in youths: applying item response theory to clinical data

Our goals in this article were to use item response theory (IRT) to assess the relation of depressive symptoms to the underlying dimension of depression and to demonstrate how IRT-based measurement strategies can yield more reliable data about depression severity than conventional symptom counts. Participants were 3,403 children and adolescents from 12 contributing clinical and nonclinical samples; all participants had received the Kiddie Schedule of Affective Disorders and Schizophrenia for School-Aged Children. Results revealed that some symptoms reflected higher levels of depression and were more discriminating than others. Furthermore, use of IRT-based information about symptom severity and discriminability in the measurement of depression severity was shown to reduce measurement error and increase measurement fidelity.     

Consolidation and long-term retention of an implanted behavioral memory

Hypothesized circuitry enabling information storage can be tested by attempting to implant memory directly in the brain in the absence of normal experience. Previously, we found that tone paired with activation of the cholinergic nucleus basalis (NB) does induce behavioral memory that shares cardinal features with natural memory; it is associative, highly specific, rapidly formed, consolidates and shows intermediate retention. Here we determine if implanted memory also exhibits long-term consolidation and retention. Adult male rats were first tested for behavioral responses (disruption of ongoing respiration) to tones (1-15 kHz), yielding pre-training behavioral frequency generalization gradients. They next received 3 days of training with a conditioned stimulus (CS) tone (8.0 kHz, 70 dB, 2s) either paired (n=7) or unpaired (n=6) with moderate electrical stimulation of the nucleus basalis (～ 65 μA, 100 Hz, 0.2s, co-terminating with CS offset). Testing for long-term retention was performed by obtaining post-training behavioral frequency generalization gradients 24h and 2 weeks after training. At 24h post-training, the Paired group exhibited specific associative behavioral memory, manifested by larger responses to the CS frequency band than the Unpaired group. This memory was retained 2 weeks post-training. Moreover, 2 weeks later, the specificity and magnitude of memory had become greater, indicating that the implanted memory had undergone consolidation. Overall, the results demonstrate the validity of NB-implanted memory for understanding natural memory and that activation of the cholinergic nucleus basalis is sufficient to form natural associative memory.     

Quantified choice of root-mean-square errors of approximation for evaluation and power analysis of small differences between structural equation models

MacCallum, Browne, and Cai (2006) proposed a new framework for evaluation and power analysis of small differences between nested structural equation models (SEMs). In their framework, the null and alternative hypotheses for testing a small difference in fit and its related power analyses were defined by some chosen root-mean-square error of approximation (RMSEA) pairs. In this article, we develop a new method that quantifies those chosen RMSEA pairs and allows a quantitative comparison of them. Our method proposes the use of single RMSEA values to replace the choice of RMSEA pairs for model comparison and power analysis, thus avoiding the differential meaning of the chosen RMSEA pairs inherent in the approach of MacCallum et al. (2006). With this choice, the conventional cutoff values in model overall evaluation can directly be transferred and applied to the evaluation and power analysis of model differences.     

The association between infants' self-regulatory behavior and MAOA gene polymorphism

Self-regulatory behavior in early childhood is an important characteristic that has considerable implications for the development of adaptive and maladaptive functioning. The present study investigated the relations between a functional polymorphism in the upstream region of monoamine oxidase A gene (MAOA) and self-regulatory behavior in a sample of Chinese infants at 6 months of age. Self-regulation was assessed by observing infants' behavior of orienting visual attention away from a threatening event in the laboratory situation. The results indicated that regulatory behavior was associated with the functional MAOA gene polymorphism in girls, but not boys. Girls with 4/4 genotypes displayed significantly higher regulation than girls with 3/3 and 3/4 genotypes. The present study provided evidence for gender differences on the role of MAOA gene polymorphism in socioemotional functioning in the early years.     

索萨的德性知识论

基于对内在论与外在论、基础论与融贯论等当代知识论主流理论的批判,索萨(Erenst Sosa)建构了新的知识理论:德性知识论.德性知识论的提出对当代知识论研究具有导向性的意义,也可以说,引领了当代知识论的合理重建.但该理论仍然受到主流学者的围剿,并没能有效完成知识论的重建任务.     

不同程度考试焦虑个体对威胁性刺激注意机制的差异

本研究采用线索提示实验范式,旨在考察考试焦虑个体对与考试有关和与考试无关刺激在注意机制上的差异。研究选取被试149名,分别采用TAS,STAI-T以及BDI量表进行高、低考试焦虑被试的筛选。问卷结果显示,TAS与STAI-T、BDI均有较高的正相关。行为实验结果显示,高、低考试焦虑个体对与考试相关的刺激在注意卷入上不存在显著差异,但是与低考试焦虑个体相比,高考试焦虑个体对与考试相关的刺激上出现了注意脱离困难。     

大学生生命认知和生命价值取向的发展特点

在生命教育的社会背景下,以上海四所高校的一年级和三年级的812名在校本科生为研究对象,运用造句和模拟遗书等投射方式,并结合小组访谈等形式,旨在测查大学生对生命过程与死亡现象的认知特征,及对生命意义的价值取向,以此探究当代大学生的生命认知和生命价值取向的发展特点。结果发现：（1）当代大学生对生命的认知以表达态度为主,具有积极向上、珍爱生命的特点;而在对死亡的认知上,则主要采用本质认知的方式进行表述,以中性、概括、简洁为主要特点;（2）总体来看,女生比男生对生命过程和死亡现象的认知更为积极,体悟更深;（3）在生命价值取向方面,当大学生更多地表现出关顾他人的价值取向,并伴有强烈的家庭责任意识。
