Four Covariance Structure Models for Canonical Correlation Analysis: A COSAN Modeling Approach

The mathematical connection between canonical correlation analysis (CCA) and covariance structure analysis was first discussed through the Multiple Indicators and Multiple Causes (MIMIC) approach. However, the MIMIC approach has several technical and practical challenges. To address these challenges, a comprehensive COSAN modeling approach is proposed. Specifically, we define four COSAN-CCA models to correspond with four possible combinations of the data to be analyzed and the unique parameters to be estimated. In terms of the data, one can analyze either the unstandardized or standardized variables. In terms of the unique parameters, one can estimate either the weights or loadings. Besides the unique parameters of each COSAN-CCA model, all four COSAN-CCA models also estimate the canonical correlations as their common parameters. Taken together, the four COSAN-CCA models provide the correct point estimates and standard error estimates for all commonly used CCA parameters. Two numeric examples are used to compare the standard error estimates obtained from the MIMIC approach and the COSAN modeling approach. Moreover, the standard error estimates from the COSAN modeling approach are validated by a simulation study and the asymptotic theory. Finally, software implementation and future extensions are discussed.     

Dominance and competence face to face: Dissociations obtained with a reverse correlation approach

The article explores whether the traits representing the dimensions underlying the structure of facial and non-facial impressions are similarly mapped in the face space. Two studies examine whether the trustworthiness-by-dominance and the warmth-by-competence two-dimensional models overlap in face perception. In Study 1 (N = 200), we used a reverse-correlation task to obtain classification images (CIs) reflecting how each dimension is mapped onto a face. Results show that the similarity between CIs was higher between warmth and trustworthiness than between competence and dominance. In Study 2 (N = 31) the evaluations of each CI on each social dimension show a higher dissociation between dominance and competence than between trustworthiness and warmth. These results, obtained at both perceptual and judgment levels, suggest that there is only a partial correspondence between the two models that seems to be driven by the relationship that the competence and dominance dimensions establish with valence.     

Validation Study of the Orientation Model: A Dual‐Process Assessment Framework

The orientation model is a multidimensional dual‐process assessment framework composed of 4 empirically validated instruments of cognitive processing, attachment, empathy, and introspection. It lends counselors a flexible means to assess client processing patterns relevant to clinical practice. The author used 375 participant responses to determine whether selected subscales align with analytic and experiential dual processes. Results suggest that the orientation model can serve as a dispositional framework for counseling practice. Implications and directions for future research are suggested.     

认知诊断模型中项目水平模型比较统计量的健壮性

使用模拟研究方法比较了以往研究中提出的基于观察信息矩阵、三明治矩阵的Wald（分别表示为W_Obs、W_Sw）、似然比（Likelihood Ratio）统计量以及新提出的基于经验交叉相乘信息矩阵的Wald统计量（W_XPD）在模型——数据失拟条件下进行项目水平上模型比较时的表现。结果显示：（1）W_Sw的一类错误控制率有很强的健壮性。（2）W_XPD在Q矩阵错误设定的大多数条件下的表现优于W_Sw。结论：模型—数据拟合良好时可以使用W_Sw进行项目水平上的模型比较,当模型与数据失拟时W_XPD可能是更好的选择。     

Discussing the therapeutic setting in child and adolescent psychoanalytic psychotherapy

The aim of this paper is to contribute to a debate on the particular characteristics of the therapeutic setting in child and adolescent psychoanalytic psychotherapy and its differences from the setting in adult therapy. In our opinion, there is a fundamental difference between these two, as in child and adolescent psychotherapy two distinct aspects co-exist and in some areas, overlap. In this paper, we attempt to delineate these two aspects, following Green’s division of the analytical setting into the active matrix and the casing. We propose that in child and adolescent psychotherapy the therapeutic contract, the active matrix, concerning the necessary conditions for making a therapy psychoanalytic – namely, the therapist’s free-floating attention and the patient’s free associations – is agreed between the therapist and the child/adolescent. We argue that in contrast, the contract regarding the casing – the timings of sessions, the fees and so on – is agreed primarily with the parents or carers of the child/adolescent. Ruptures and possible modifications in both the matrix and the casing of the setting are discussed through the presentation of clinical material.     

Influence of plastic strain localisation on the mechanical properties of metal matrix composites

The aim of the present study is to reveal the most critical underlying factor influencing the mechanical properties of metal matrix composites (MMCs). It is shown that the mechanical properties of MMCs are essentially governed by the degree of strain localisation during plastic deformation. In other words, the MMCs exhibit superior mechanical performance only if the strain localisation is obviously inhibited and the accumulated stresses can be effectively transferred out. The work provides a new perspective in guiding the design of next-generation high-performance MMCs by suppressing the strain localisation as far as possible.     

幸福者更适应,还是适应者更幸福?——基于大学新生的追踪研究

本研究对122名大学新生进行了半年追踪,采用交叉滞后分析法考察适应性与幸福感之间的关系。入学三个月时初次测试（T1）,初测半年之后后测（T2）。结果发现：（1）幸福感和适应性之间显著正相关,同时预测的效果高于继时预测;（2）交叉滞后相关分析表明,适应性T1对幸福感T2的预测（r=0.50）高于幸福感T1对适应性T2的预测（r=0.32）;（3）学习适应性T1（18%）和人际适应性T1（11%）共同预测主观幸福感T1中29%的变异;（4）控制初测总体适应性T1（31%）,对大学的认可度T2（21%）和个人情绪适应性T2（3%）还可以解释幸福感T2中24%的变异。因此,本研究发现大学生适应者更幸福,而不是幸福者更适应。该结果对于提升大学生的幸福感具有一定的教育启示意义。     

行为遗传学研究之新进展

自上世纪80年代以来,行为遗传学取得了长足的进展。在定量遗传学方面,共享环境和非共享环境概念的引入深化了人们对环境作用的认识;对于环境和遗传关系,不仅认识到基因型-环境的交互作用可能存在三种形式,还揭示出遗传对环境测量的影响——基因型-环境的相关。分子遗传学作为新兴的研究途径,目前以寻找基因为主,将来则以认识基因如何工作为重。行为遗传学的发展前景将是定量遗传学和分子遗传学以行为基因组学为中心的整合。     

大学生英语学习过程中认知因素与情感因素对学业成绩的影响

利用调查问卷法对152名大学生就英语学习中的认知因素(以学习风格和学习策略为核心)和情感因素(以成就动机和学习意愿为核心)对于学习成绩的影响进行了相关研究,继而通过多元回归方法与路径分析技术,探讨了三者之间的因果关系。研究结果表明,学习意愿、成就动机、学习风格与英语成绩之间具有显著性相关,而学习策略与英语成绩之间的相关不显著。学习风格作为中介变量在对学生的英语学习有着重要的影响。学习意愿与成就动机通过学习风格而问接地作用于英语学习绩效。
