Parental Health and Children’s Functioning in Immigrant Families: Family Roles and Perceived Treatment at School

Although parents’ health condition is generally thought to be related to their involvement in their children’s functioning, the possible dynamics behind the scenes in school contexts with immigrant children has received little attention. This study examined the association between parents’ health condition and their children’s academic and behavioral functioning, as well as the mediation effects of parents’ school engagement and children’s perceived treatment at school among 607 immigrant families with 10- to 12-year-old children. Using structural equation modeling, the results indicated that parents’ poor health condition was associated with children’s increased behavioral problems. Parents’ school engagement fully mediated the association between parental health condition and children’s academic achievement and partially mediated the association between parental health condition and children’s behavior problems. Notably, higher levels of parents’ school engagement were associated with increased behavior problems, demonstrating a unique feature in these immigrant children’s developmental functioning. Higher levels of perceived harsh treatment by peers at school due to children’s immigrant identity were associated with these children’s greater risks of behavior problems. The results suggested what may lie behind the scenes in these children’s behavioral problems is that many of these children who act out and are brought to the school office for disciplinary issues may suffer from perceived discrimination and bad treatment by their peers. The findings provide important implications for researchers, healthcare practitioners, and educators seeking to understand this subpopulation and to design and implement family support and prevention programs for young adolescents from immigrant backgrounds.     

人脑加工自我参照任务的时空特点:来自ERP的证据

以自我参照加工任务为范式,实验采用事件相关电位(ERP)技术,探讨了自我参照加工中符合判断和不符合判断加工的时间进程和大脑神经机制。结果发现,自我参照加工在时间上可以概括分为三个阶段:注意分配阶段N1(80~150 ms)波幅出现自我参照结果的差异;语义整合阶段N2(250~450 ms)波幅和潜伏期出现自我参照结果的差异;评价判断阶段P3(450~700 ms)波幅和潜伏期出现自我参照结果的差异。从我们选择的大脑兴趣区激活水平上分析发现,自我信息在大脑中的激活似乎是一个由右及左,由后及前再及后的动态变化过程。研究结果丰富了自我参照加工的已有结果,并且对未来研究具有一定的启示意义。     

移动医疗视域下HIV/AIDS患者自我管理体验及需求的质性研究

采用目的抽样选取成都市、绵阳市及西昌市19名HIV/AIDS患者作为研究对象,采用描述性质性研究对研究对象进行半结构式访谈,对访谈结果进行主题分析,共提炼出一级主题5个：（1）患者有基于移动医疗的自我管理需求;（2）基于移动医疗自我管理平台期望载体及形式;（3）基于移动医疗的医疗或行为管理需求;（4）基于移动医疗的角色管理需求;（5）基于移动医疗的情绪管理需求。患者对基于移动医疗的自我管理平台有较高接受度。可设计开发易用性与隐私性强的移动医疗平台,通过提供疾病知识、线上诊疗、疾病监测与心理社会支持等功能,提升患者自我管理能力。

     

基层医院伦理委员会建设存在问题及对策

基层医院以承担本地区人民群众的健康保障工作为首要任务,以临床工作为主,科研工作开展相对较少,伦理委员会的建设存在较大问题。针对基层医院伦理委员会在建设过程中存在认识和重视程度不足、独立性欠缺、规章制度不完善、人员组成及审查不规范以及缺乏有效指导和监管等问题,结合基层医院的特点和功能定位,在完善工作制度和流程、组建全面合理代表性强的伦理委员会以及加强培训提高认识等方面提出比较科学可行的对策,为基层医院伦理委员会的规范化建设提供参考。     

不同加工与记忆编码关系的ERP研究

通过事件相关电位(ERPs)记录,探讨了深、浅2种加工与记忆编码的相互关系。研究结果表明,（1）在深、浅两种加工条件下,首次使用汉字材料,获得了ERP相继记忆效应（Dm),随后再认正确的ERPs比随后再认不正确的ERPs有更大的晚正成分。（2）深加工的Dm效应始于N2波的前支（230－280ms)和N2波之后（395－800ms);而浅加工的Dm效应发生在345－490ms之间。深、浅加工的Dm效 涉及不同的脑区,这一结果支持深、浅两种加工的Dm效应可能是分离的结论。

基于fNIRS的运动执行与运动想象脑激活模式比较

使用《运动想象问卷−修订版》筛选出的30名被试(男女各半), 采用功能性近红外光谱成像技术(fNIRS)监测被试在执行实际举哑铃(男生, 4磅和8磅; 女生, 2磅和4磅)任务和想象举同等重量哑铃任务时, 其大脑皮层氧合血红蛋白浓度的变化。结果发现：男女被试在运动执行与运动想象任务下都激活了主运动皮层; 且运动执行的大脑激活水平高于运动想象。在执行实际运动任务时, 运动强度显著影响大脑皮层血氧浓度的变化, 表现出左半球偏侧化优势; 在执行想象运动任务时, 运动强度没有影响大脑皮层血氧浓度的变化, 且无偏侧化现象。     

辱虐管理的应对：基于人际拒绝的多动力模型分析

问题意识对学业成绩的影响:笔记策略的中介作用——基于大学生笔记文本的内容分析

基于笔记文本的内容分析法系统地考察了大学生的问题意识和笔记策略状况,以及二者与学业成绩的关系。结果发现:(1)基于笔记文本的内容分析法能有效地了解大学生的问题意识状况,以及笔记策略的使用种类、频次和实际水平;(2)大学生笔记策略种类丰富且存在优势笔记策略,但问题意识相对薄弱;在问题意识、笔记策略和学业成绩上均存在显著的水平和性别差异。(3)大学生的问题意识、策略数量、策略频次与学业成绩之间呈显著正相关,问题意识对学业成绩的影响以笔记策略数量为中介。     

Determinants of Standard Errors of MLEs in Confirmatory Factor Analysis

This paper studies changes of standard errors (SE) of the normal-distribution-based maximum likelihood estimates (MLE) for confirmatory factor models as model parameters vary. Using logical analysis, simplified formulas and numerical verification, monotonic relationships between SEs and factor loadings as well as unique variances are found. Conditions under which monotonic relationships do not exist are also identified. Such functional relationships allow researchers to better understand the problem when significant factor loading estimates are expected but not obtained, and vice versa. What will affect the likelihood for Heywood cases (negative unique variance estimates) is also explicit through these relationships. Empirical findings in the literature are discussed using the obtained results.
