A Bayesian Approach to More Stable Estimates of Group-Level Effects in Contextual Studies

Multilevel analyses are often used to estimate the effects of group-level constructs. However, when using aggregated individual data (e.g., student ratings) to assess a group-level construct (e.g., classroom climate), the observed group mean might not provide a reliable measure of the unobserved latent group mean. In the present article, we propose a Bayesian approach that can be used to estimate a multilevel latent covariate model, which corrects for the unreliable assessment of the latent group mean when estimating the group-level effect. A simulation study was conducted to evaluate the choice of different priors for the group-level variance of the predictor variable and to compare the Bayesian approach with the maximum likelihood approach implemented in the software Mplus. Results showed that, under problematic conditions (i.e., small number of groups, predictor variable with a small ICC), the Bayesian approach produced more accurate estimates of the group-level effect than the maximum likelihood approach did.

The analysis of bridging constructs with hierarchical clustering methods: An application to identity

When analyzing psychometric surveys, some design and sample size limitations challenge existing approaches. Hierarchical clustering, with its graphics (heat maps, dendrograms, means plots), provides a nonparametric method for analyzing factorially-designed survey data, and small samples data. In the present study, we demonstrated the advantages of using hierarchical clustering (HC) for the analysis of non-higher-order measures, comparing the results of HC against those of exploratory factor analysis. As a factorially-designed survey, we used the Identity Labels and Life Contexts Questionnaire (ILLCQ), a novel measure to assess identity as a bridging construct for the intersection of identity domains and life contexts. Results suggest that, when used to validate factorially-designed measures, HC and its graphics are more stable and consistent compared to EFA.     

Production planning of Pakistan Tobacco Company (PTC) using quantitative and multiple‐criteria decision analysis—A case in‐point

The main purpose of this paper is to improve the production planning of Pakistan Tobacco Company by selecting the most preferred brand and subsequently generating maximum profit from it. As the company produces a variety of products, the technique of multi criteria decision making is used to select the most preferred brand. To generate the maximum output from the preferred brand, different methods of qualitative managerial analysis are used, which include decision analysis to decide “why and where” the manufacturing should be carried out, transportation model to minimize the logistics cost while meeting the demand, and linear programming technique to maximize the profit generated in 2014–2015. The result obtained from analytical hierarchy process shows that the most preferred brand of the company with respect to price, quality, and comfort is John Player Gold Leaf. The decision analysis explains that this brand should be manufactured in the Jhelum factory of the company as it is more cost‐effective to produce and there is a high availability of resources. Transportation model minimizes the logistics cost of this brand from the 2 factories while meeting the demand at each provinces, central warehouse. Linear programming contributes in generating a profit of 32.738 billion PKR with an amount of 0.35 million PKR, which is more than that of the current profit of the company in the year. These results will allow the top management of the company to take corrective decisions well in time, gain a core competency in cost reduction, and make the supply chain process more efficient.     

Are Perfectionism Dimensions Vulnerability Factors for Depressive Symptoms After Controlling for Neuroticism? A Meta‐analysis of 10 Longitudinal Studies

Extensive evidence suggests neuroticism is a higher‐order personality trait that overlaps substantially with perfectionism dimensions and depressive symptoms. Such evidence raises an important question: Which perfectionism dimensions are vulnerability factors for depressive symptoms after controlling for neuroticism? To address this, a meta‐analysis of research testing whether socially prescribed perfectionism, concern over mistakes, doubts about actions, personal standards, perfectionistic attitudes, self‐criticism and self‐oriented perfectionism predict change in depressive symptoms, after controlling for baseline depression and neuroticism, was conducted. A literature search yielded 10 relevant studies (N = 1,758). Meta‐analysis using random‐effects models revealed that all seven perfectionism dimensions had small positive relationships with follow‐up depressive symptoms beyond baseline depression and neuroticism. Perfectionism dimensions appear neither redundant with nor captured by neuroticism. Results lend credence and coherence to theoretical accounts and empirical studies suggesting perfectionism dimensions are part of the premorbid personality of people vulnerable to depressive symptoms.

在押毒品犯人格类型的聚类分析

目的 :探讨毒品犯的人格分类模型。方法 :以 378名在押毒品犯接受CPI测验数据为基础 ,在 2 0个变量组成的 2 0维空间内对毒品犯进行Q型聚类。结果 :采用分层聚类中的Q型聚类方法分析在押毒品犯的人格类型 ,得到 3种基本的人格类型 ,经F检验和LSD检验 ,表明 3种人格类型在各分量表上的得分具有十分显著的差异。结论 :怯弱 -不成熟型、独立 -不成熟型和可控制 -不成熟型 3种人格类型是一个有效的分类模型 ;这一分类模型有助于监狱开展对在押毒品犯的分类矫治工作     

儿童期逆境与基因对男性服刑人员攻击性的影响

暴力再犯危险性评估是当今再犯危险性评估工作中的重点, 其中, 攻击性是服刑人员暴力再犯行为稳定的个体因素。对攻击性进行研究, 有助于预防和降低服刑人员在假释或出狱后的暴力再犯行为风险, 关系社会的长治久安。研究表明, 遭受儿童期逆境和携带易感基因(如MAOA-uVNTR低活性等位基因)是导致攻击行为的重要因素。但在现有的研究中, 儿童期逆境的计分方式局限于简单的线性加总, 或所依据的统计模型忽略逆境各维度之间的交互作用和非线性关系; 在服刑人员攻击性的评估中未考虑攻击性的亚类, 而且多使用自报告的量表测评, 这些问题制约了评估的有效预测力。本研究拟通过建立潜在类别模型, 分析男性服刑人员和普通成年人群在儿童期逆境上的亚类; 以实验与问卷测量结果、司法行为记录作为攻击性指标, 揭示儿童期逆境如何影响个体的主动性攻击、反应性攻击及暴力犯罪行为, 重点探讨儿童期逆境潜在类别对主动性攻击和反应性攻击的影响, 以及MAOA-uVNTR、COMT Val158Met、5-HTTLPR基因多态性在其中的调节作用。研究结果有助于找出高攻击性个体的生物遗传指标, 从而发现受儿童期逆境经历影响的易感人群, 为暴力行为的风险预测以及针对暴力攻击行为的行为矫正和相关药物设计提供理论和实证参考, 提高相关工作的效率。
