兼顾两种匹配的考试抄袭统计量研究评述

考试抄袭统计量是专门用于识别抄袭的统计指标。它们是以被怀疑抄袭者和抄袭来源匹配反应的数目为基础建立的,按其考虑的匹配反应信息可分为两类:一类只考虑被怀疑抄袭者和抄袭来源间的错误答案匹配;另一类同时考虑两者错误答案匹配和正确答案匹配。由于第一类抄袭统计量对那些只从抄袭来源处抄袭正确答案的抄袭者检测不敏感,所以存在缺陷;第二类抄袭统计量兼顾两种匹配,考虑的信息更全面。s2、g2、ω是具有代表性的第二类抄袭统计量,它们在测量理论基础、被怀疑抄袭者和抄袭来源的异常相似反应模式确定方法及考试抄袭检测效能等方面存在差异,在抄袭识别应用中应合理选择。     

Differential hepatic gene expression in the broiler chicken in response to the combined stressors of food withdrawal, catching and transport at the end of production

Broiler (meat) chickens experience the combined acute stressors of food withdrawal, catching and transport (FCT) prior to slaughter as part of normal commercial practice at the end of their lives. This has associated physiological consequences, potentially affecting both welfare and meat quality, some of which are mediated through altered hepatic function. This study compared global hepatic gene expression between control birds and those exposed to commercial FCT using 20K chicken oligonucleotide microarrays. In response to FCT, 733 genes were differentially expressed of which 486 could be mapped onto the genome. The principal molecular and cellular functions thus affected by FCT involved lipid and carbohydrate metabolism with a suppression of mRNA expression for genes involved in lipogenesis, glycolysis and glycogenolysis and an induction of those involved in gluconeogenesis, fatty acid metabolism and ketone synthesis. There was also significant differential expression of genes associated with cellular control and immune function. These stressful events associated with FCT in commercial broiler chickens altered expression of hepatic genes associated with energy metabolism, with exhaustion of stored hepatic and pectoral muscle glycogen. A better understanding of FCT-induced stress through the use of gene expression arrays may in future inform husbandry practices, to improve both welfare and meat quality.     

Teaching Children with Autism Spectrum Disorder to Mand “Where?”

A modified multiple-baseline design across participants was used to evaluate a procedure for teaching the mand “Where?” to 3 children with autism. The participants were 3 and 5?years old and were participating in an intensive applied behavior analysis program. The participants were able to mand for items they wanted when the items were not in sight but were unable to ask where an item was located. The procedure consisted of a preference assessment for play activities, contrived conditioned motivating operations (CMO’s), prompting the children to mand “Where,” and consequences for correct and incorrect responding. Each contrived CMO consisted of an opportunity for the child to mand “Where” while playing with a selected activity, prompting the child to mand, and reinforcing a correct response by answering the question “Where.” Two of the participants learned to mand “Where” after training with 1 CMO and the mand generalized to novel contrived situations, activities, and the natural environment and was maintained over time (up to 4-weeks), whereas one participant required training with a second CMO before generalization occurred.     

Risk perception,illusory superiority and personal responsibility during COVID-19: An experimental study of attitudes to staying home

Little is known about how different government communication strategies may systematically affect people’s attitudes to staying home or going out during the COVID-19 pandemic, nor how people perceive and process the risk of viral transmission in different scenarios. In this study, we report results from two experiments that examine the degree to which people’s attitudes regarding the permissibility of leaving one’s home are (1) sensitive to different levels of risk of viral transmission in specific scenarios, (2) sensitive to communication framings that are either imperative or that emphasize personal responsibility, or (3) creating ‘loopholes’ for themselves, enabling a more permissive approach to their own compliance. We find that the level of risk influences attitudes to going out, and that participants report less permissive attitudes to going out when prompted with messages framed in imperative terms, rather than messages emphasizing personal responsibility; for self-loopholes, we find no evidence that participants’ attitudes towards going out in specific scenarios are more permissive for themselves than for others. However, participants report they are more rigorous in staying home than others, which may cause moral licensing. Additionally, we find that age is negatively associated with permissive attitudes, and that male participants are more permissive to going out. Thus, during phases where it is important to promote staying home for all scenarios, including those perceived to be low-risk, imperative communication may be best suited to increase compliance.     

创造性思维中语义搜索过程：基于答案累积时间函数和语义相似性的量化分析

通过描绘发散性思维测验(物品多用途, AUT)中答案生成在累积函数和语义相似性等一系列参数上的量化特征, 揭示创造性思维的语义搜索过程。结果发现：(1)新颖AUT条件中, 语义搜索呈现与自由联想类似的负加速特点, 但搜索速度较寻常AUT条件更慢。(2)新颖AUT条件中所生成的答案与题目(即物品)均具有较低的语义相似性, 且显著小于寻常AUT条件。(3)新颖AUT条件中生成的答案比寻常AUT条件表现出显著更低的聚类程度, 其中可聚类答案和未聚类答案与题目的语义相似度均较低, 且不存在显著差异, 二者在新颖性上也不存在显著差异。以上结果说明了创造性思维的语义信息搜索过程具有与自由联想类似的激活扩散特征, 但总体搜索速度较慢。新颖性要求使得个体在最初搜索时便开始摆脱题目的语义限制而进行远距离搜索(避免就近搜索), 并倾向于在每个语义场中只生成一个答案(避免局部搜索), 但也可能会在远离题目的语义场中生成多个同类别答案。     

Latent Profile Analysis of Psychopathy in Chinese Female Offenders

The present study aimed to identify meaningful subtypes of psychopathy among Chinese female offenders. A Latent Profile Analysis (LPA) based on the scores of the Levenson Self-Report Psychopathic Scale was performed in a sample of Chinese female prisoners (N?=?279, M age?=?45.43, SD?=?8.62). The LPA yielded three profiles: “low psychopathy group” (27.6%), “moderate psychopathy group” (66.7%), and “high egocentricity and antisocial group” (5.7%). These profiles differed on all outcome variables including anxiety, depression, reactive aggression, and proactive aggression. The high egocentricity and antisocial group had a greater risk for anxiety, recidivism, impulsiveness, and aggression. Overall, the findings support the existence of psychopathy subtypes in non-Western cultural contexts, suggest gender similarities in the manifestation of psychopathy traits, and further the understanding of psychopathy typologies.

婴儿对语音和非语音的感知:认知和神经机制

婴儿听觉感知能力的发展对于他们未来的语言学习和社会化都具有重要意义。过去大量的研究主要关注语音感知方面,只有较少的研究将非语音感知纳入考虑之中,但了解非语音感知的特征和机制将有助于增加研究者对听觉加工以及儿童发育的认识。该文分别介绍了婴儿语音感知中的三种偏好——对语音、“婴儿语”和母语的偏好,并尝试着将非语音分为音乐、人类的非言语发声、环境声音三类进行阐述。通过对比这两大类声音的感知得到婴儿可能存在语音感知的左脑偏侧化和音乐感知的右脑偏侧化现象,但这也尚存争议,目前有特定领域模型、特定线索模型和脑网络模型三种理论对偏侧化现象的认知机制进行解释。
