Reliability coefficients for multiple group item response theory models

Reliability of scores from psychological or educational assessments provides important information regarding the precision of measurement. The reliability of scores is however population dependent and may vary across groups. In item response theory, this population dependence can be attributed to differential item functioning or to differences in the latent distributions between groups and needs to be accounted for when estimating the reliability of scores for different groups. Here, we introduce group-specific and overall reliability coefficients for sum scores and maximum likelihood ability estimates defined by a multiple group item response theory model. We derive confidence intervals using asymptotic theory and evaluate the empirical properties of estimators and the confidence intervals in a simulation study. The results show that the estimators are largely unbiased and that the confidence intervals are accurate with moderately large sample sizes. We exemplify the approach with the Montreal Cognitive Assessment (MoCA) in two groups defined by education level and give recommendations for applied work.     

反刍思维的脑功能网络机制

反刍思维是指个体在经历了消极生活事件后不由自主地反复思考该事件的产生原因、经过和结果, 表现出负性自我参照加工、消极情绪性以及持续性的特点。采用脑功能网络分析方法, 研究者发现反刍思维的上述三个特点分别与默认网络内部的异常活动模式、突显网络功能连接的改变以及注意相关网络之间的异常耦合有关。未来研究应进一步明确反刍思维与相关脑网络活动之间的因果关系, 探究反刍思维脑功能网络的结构基础, 同时也应关注反刍思维及其脑网络的老龄化特征, 并致力于探索有效干预反刍思维的神经调控技术。     

Wittgenstein and the Dualism of the Inner and the Outer

A dualism characteristic of modern philosophy is the conception of the inner and the outer as two independently intelligible domains. Wittgenstein’s attack on this dualism contains deep insights. The main insight (excavated from §304 and §293 of the Philosophical Investigations) is this: our sensory consciousness is deeply shaped by language and this shaping plays a fundamental role in the etiology of the dualism. I locate this role in the learning of a sensation-language (as described in §244), by showing that this learning is, under another aspect, the incision of language, namely the infliction of cuts upon certain natural-primitive unities between the inner and the outer. These cuts, driven by powerful forces, eventually harden into an entrenched division between the inner and the outer, thereby providing a constant soil for the dualism. That this dualism is rooted in the very learning of a language is cause for ambivalence about language.     

应用罗哌卡因对腹腔镜胆囊切除术后疼痛效应观察

探讨在腹腔镜胆囊切除术术前应用罗哌卡因切口浸润结合术中腹腔喷洒对术后疼痛的缓解效应.将80例患者随机分为四组（各20例）.试验A组：应用0.5％的罗哌卡因20ml进行胆囊床喷洒;试验B组：应用0.5％的罗哌卡因10ml进行胆囊床喷洒,同时10ml进行膈下喷洒;对照A组：采用生理盐水20ml进行胆囊床注射;对照B组：采用生理盐水10ml进行胆囊床注射,同时10ml进行膈下喷洒.对术后疼痛情况进行评价.试验A、B组术后1h、4h、8h腹腔内疼痛、切口疼痛及咳嗽时疼痛VAS评分与对照A、B组相比差异有统计学意义（P＜0.05）;试验B组1h、4h、8h、24h、48h肩部疼痛VAS评分与对照B组相比差异有统计学意义（P＜0.05）,试验A组1h、4h、8h、24h、48 h肩部疼痛VAS评分比试验B组相比明显高,差异有统计学意义（P＜0.05）.腹腔镜胆囊切除术术前应用罗哌卡因切口浸润结合术中腹腔喷洒,可有效减轻患者疼痛,对于促进康复具有积极作用.     

不同血液净化方式对维持性血液透析患者微炎症指标及Fetuin-A的相关性研究

通过研究高通量血液透析(HFHD)和血液透析滤过(OL-HDF)两种血液净化模式对尿毒症患者血清白介素-1β(IL-1β)、超敏C反应蛋白(hs-CRP)、降钙素原(PCT)、钙(Ca)、磷(P)、胎球蛋白A(Fetuin-A)水平的影响,旨在求其相关性.按不同血液净化模式,将维持性血液透析(MHD)患者随机分为HFHD组(A组)30例,OL-HDF组(B组)30例,健康对照组(C组)16例,通过测定A组、B组、C组透析前、A组、B组透析6个月后各项化验指标,经过统计学分析比对发现A组、B组血清Fetuin-A与IL-1β、hs-CRP、P、Ca×P呈负相关.本研究证明,MHD患者存在微炎症状态,其钙化抑制因子Fetuin-A较正常人明显降低,长期OL-HDF治疗(治疗大于6个月)对于改善MHD患者微炎症状态及升高钙化抑制因子Fetuin-A效果均明显优于HFHD.     

工作团队领导心理资本对成员组织公民行为的影响机制：多层次模型

本研究采用问卷调查法, 以某国有企业在10个地市的66个工作团队369名企业员工为调查对象, 在控制被试的教育程度、工作经验及人口统计学变量之后, 运用多层线性模型技术分析团队领导心理资本与团队成员心理资本及其组织公民行为的关系。结果发现：(1)工作团队领导心理资本对团队成员组织公民行为存在积极影响, 团队成员心理资本是领导心理资本与团队成员组织公民行为之间跨层次的中介变量; (2)工作团队领导心理资本对团队成员心理资本与组织公民行为关系的调节效应不显著。     

On the Likelihood Ratio Tests in Bivariate ACDE Models

The ACE and ADE models have been heavily exploited in twin studies to identify the genetic and environmental components in phenotypes. However, the validity of the likelihood ratio test (LRT) of the existence of a variance component, a key step in the use of such models, has been doubted because the true values of the parameters lie on the boundary of the parameter space of the alternative model for such tests, violating a regularity condition required for a LRT (e.g., Carey in Behav. Genet. 35:653–665, 2005; Visscher in Twin Res. Hum. Genet. 9:490–495, 2006). Dominicus, Skrondal, Gjessing, Pedersen, and Palmgren (Behav. Genet. 36:331–340, 2006) solve the problem of testing univariate components in ACDE models. Our current work as presented in this paper resolves the issue of LRTs in bivariate ACDE models by exploiting the theoretical frameworks of inequality constrained LRTs based on cone approximations. Our derivation shows that the asymptotic sampling distribution of the test statistic for testing a single bivariate component in an ACE or ADE model is a mixture of χ ² distributions of degrees of freedom (dfs) ranging from 0 to 3, and that for testing both the A and C (or D) components is one of dfs ranging from 0 to 6. These correct distributions are stochastically smaller than the χ ² distributions in traditional LRTs and therefore LRTs based on these distributions are more powerful than those used naively. Formulas for calculating the weights are derived and the sampling distributions are confirmed by simulation studies. Several invariance properties for normal data (at most) missing by person are also proved. Potential generalizations of this work are also discussed.
