Mastery Motivation in Children with Intellectual Disability: Is there Evidence for a Down Syndrome Behavioural Phenotype?

The main purpose of the current study was to provide empirical evidence to support or refute assumptions of phenotypic deficits in motivation for children with Down syndrome (DS). Children with moderate intellectual disability (MID) associated with etiologies other than DS were recruited in an extension of a previous study that involved children with DS and typically developing children. The participants were 29 children with MID and 33 children with DS who were matched on mental age to 33 typically developing children, aged 3–8 years. Mastery motivation was assessed on task measures of curiosity, preference for challenge and persistence, as well as parental reports. There were no significant group differences on the mastery motivation tasks. Parental ratings of mastery motivation differed, with typically developing children generally being rated more highly than each of the disability groups. The view that motivational deficits are part of the DS behavioural phenotype was not supported.     

新冠肺炎疫情对我国上市港航及船舶制造企业财务状况的影响

为量化新冠肺炎疫情对我国水路运输企业财务状况的影响,本文基于Z score模型对构成水路运输产业链核心的港口、航运、船舶制造三类上市企业财务状况进行评价。通过对比疫情发生前后企业财务状况的变化,明确疫情在不同时期对水路运输企业财务状况的影响,以及对不同类企业带来的异质化影响。研究结果表明,在疫情发生初期我国水路运输业受到短期负面冲击较大,企业经营利润均出现明显下降,其中港口和船舶制造企业财务状况恶化较为显著,而航运企业财务状况受影响较小。随着国内疫情得到有效控制,水路运输业整体经营状况逐渐向好,特别是船舶制造企业得益于船舶订单量的增长,财务状况改善较为明显。港口企业恢复则较为疲软,且不同港口企业间的分化有所加剧。航运企业总体财务状况相对较为稳健。     

Do labels matter? Analysis of teachers' self-efficacy towards the autism spectrum disorder depending on the diagnostic label used (ASD or Asperger's)

Changes in the classification of autism and Asperger's syndrome led to changes in social perception of ASD. Since last criteria, studies indicate higher levels of stigma towards ASD than towards Asperger's. These prejudices are barriers to inclusive education. Thus, it is relevant (1) to evaluate pre-service teachers' self-efficacy towards the label of ASD; (2) to evaluate pre-service teachers' self-efficacy towards the label of Asperger's and (3) to compare those results to analyse whether the use of different diagnostic labels brings about different levels of self-efficacy. One hundred and eighty-six primary education pre-service teachers participated in the current study. Two adaptations of the Autism Self-Efficacy Scale for Teachers (ASSET) were used: a version with the label of ‘ASD’ (n = 96) and another for ‘Asperger's’ (n = 90). The scores obtained by the group asked about ASD were high according to the ASSET score range, while the scores obtained by the group asked about Asperger's were medium. After comparing the results, participants asked about the label ASD showed higher levels of self-efficacy than participants asked about Asperger's. These results could be a consequence of the consolidation of the ASD diagnosis among society and the higher presence of children with ASD in schools and cultural products, among other factors.     

网络个体用户遭受感染下病毒免疫滤波控制算法

网络个体用户在遭受病毒入侵干扰下,由于病毒入侵信号对单个个体用户入侵的不确定性,难以实现对病毒的有效控制和免疫。提出一种基于自适应功率谱密度特征提取的网络个体用户遭受感染下病毒免疫滤波控制算法,首先进行网络病毒面入侵信号的模型构建,设计滤波控制算法实现对网络个体用户遭受感染下的病毒免疫控制。设计网络个体用户遭受感染下的病毒免疫模型,进行网络个体用户遭受感染下病毒入侵路径和安全属性分析。设计基于自适应功率谱密度特征提取的网络个体用户遭受感染下病毒免疫滤波控制算法,实现对用户遭受感染下的病毒入侵信号的滤波检测和控制。仿真实验结果表明,该算法能有效实现对病毒入侵路径和强度幅值的准确跟踪控制,免疫滤波效果较好,对病毒信号的检测概率提高15.7%,实时性和鲁棒性优越于传统方法,保证了网络个体用户的安全。

Getting inside the insider researcher: does race-symmetry help or hinder research?

This article engages with methodological concerns connected to insider education research and the ‘race-symmetry’ shared between the researcher and teacher participants. To do this, race critical reflexive strategies are utilized to show how and why this practice productively contributed to the knowledge about race making constructed in my study, a research process I describe as getting inside my insiderness. However, these reflexive practices also helped me to develop a deeper awareness of the potential for what I now describe as White shadows to infiltrate research of this type. The conceptualization of White shadows is a useful tool to describe research practices that silence or deflect attention away from issues connected to race, and hence, White shadows help expose concerns about the potential for Whiteness to remain protected by research. There are two interconnected aims of this paper. First, to illustrate the sort of race reflexive practices called for, and in doing so, to demonstrate why they are valuable and helpful in (educational) research. Second, I hope to encourage a rethink of the insider–outsider relationship that typifies ethnographic research by shifting attention to explore the inside of insider research.     

全球知识产权研究发展态势与热点分析

基于知识图谱理论,对Web of Science核心数据集收录的1900-2016年间的知识产权相关文献的发文量、发文国家、发文学科、被引文献、关键词等进行可视化分析,研究结果表明：（1）当前知识产权研究处于稳步上升阶段,美国、英国、德国引领全球知识产权发展,中国后发优势明显,从国际合作上看,全球知识产权跨国合作研究匮乏。（2）知识产权研究趋势日趋多样化,知识产权、经济、企业在更宽更广范围内的泛在研究成为主流。（3）知识产权的研究方向主要为知识产权管理与知识产权溢出、知识产权转移与流动、新兴技术知识产权保护、知识产权与跨界资本输入等方面。
