Vice and Reason

Aristotle's account of vice presents a puzzle: (1) Viciouspeople must be guided by reason, since they act on decision(prohairesis), not on their non-rational desires. (2) And yet theycannot be guided by reason, since they are said to pay attention totheir non-rational part and not to live in accordance with reason. Wecan understand the conception of vice the reconciles these two claims,once we examine Aristotle's account of (a) the pursuit of the fine andof the expedient; (b) the connexion between vice and the pursuit ofpleasure; (c) the particular kind of regret to which the vicious personis subject.     

Exploring the Complexities of Familism and Acculturation: Central Constructs for People of Mexican Origin

We examined the relationships between three dimensions of familism: importance of family, family support, and family conflict with acculturation, assessed orthogonally (Mexican and American cultural contributions assessed independently), and the relative contribution these factors make to psychological adjustment among 248 (124 women, 124 men) adults of Mexican origin. After controlling for sociodemographic characteristics, positive associations were found between importance of family and the biculturalism of Mexican and American cultural identity; family support and Mexican cultural identity; but no associations between family conflict and level of acculturation. Psychological well-being was positively associated with Mexican cultural identity and family support, whereas psychological distress was associated with greater family conflict and lower family support. The greater relative contribution of Mexican cultural identity to familism and well-being, and the importance of assessing acculturation orthogonally are discussed.

A Qualitative Study of the Supports Women Find Most Beneficial When Dealing with a Spouse’s Sexually Addictive or Compulsive Behaviors: Insights for Pastoral Counselors and Clergy

There is currently a void in the literature regarding the kinds of support women find most beneficial when dealing with a spouse’s sexually addictive or compulsive behaviors. Addressing this void is particularly relevant for clergy, seeing as they are increasingly sought out as an initial and/or primary support for dealing with this marital issue. Using grounded theory methodology, 22 women from Canada and the USA were interviewed to find out what they found most helpful as they sought support to cope with a spouse’s sexually addictive and compulsive behaviors. Insights for pastoral counselors and clergy were highlighted.     

A Polychoric Instrumental Variable (PIV) Estimator for Structural Equation Models with Categorical Variables

This paper presents a new polychoric instrumental variable (PIV) estimator to use in structural equation models (SEMs) with categorical observed variables. The PIV estimator is a generalization of Bollen’s (Psychometrika 61:109–121, 1996) 2SLS/IV estimator for continuous variables to categorical endogenous variables. We derive the PIV estimator and its asymptotic standard errors for the regression coefficients in the latent variable and measurement models. We also provide an estimator of the variance and covariance parameters of the model, asymptotic standard errors for these, and test statistics of overall model fit. We examine this estimator via an empirical study and also via a small simulation study. Our results illustrate the greater robustness of the PIV estimator to structural misspecifications than the system-wide estimators that are commonly applied in SEMs. Kenneth Bollen gratefully acknowledges support from NSF SES 0617276, NIDA 1-RO1-DA13148-01, and DA013148-05A2.

The Behavioral Activation for Depression Scale (BADS): Psychometric Properties and Factor Structure

In Behavioral Activation (BA) for depression (Martell, C. R., Addis, M. E., & Jacobson, N. S. (2001)), which has recently received empirical support in a large randomized trial, therapists pay close attention to the function of behavior and the role of aversive controlling stimuli and escape and avoidance behavior in depression. A key variable to measure in studies of BA is when and how clients become more activated over the course of treatment. This study sought to develop an initial set of items for the Behavioral Activation for Depression Scale (BADS), submit these items to an exploratory factor analysis in an initial administration (Study 1, N = 391), and submit the resulting scale to a confirmatory factor analysis in a second administration (Study 2, N = 319). Results indicated four factors (Activation, Avoidance/Rumination, Work/School Impairment, and Social Impairment) with good factor structure, internal consistency, and test-retest reliability. Evidence for construct and predictive validity is presented.     

慢性乙型肝炎抗病毒治疗的进展

针对目前乙型肝炎的抗病毒治疗现状以及临床用药中存在的问题进行分析,就如何选择合理治疗方法提出医疗原则,认为对于慢性乙型肝炎的抗病毒治疗,应坚持联合治疗和个体化治疗,长期用药和间断反复用药结合,把病毒抑制到最低水平,以使发生原发性肝癌的可能性减至最小。     

忽视性阅读障碍的研究概况

首先介绍了忽视性阅读障碍(neglect dyslexia, ND)的概念,随后描述了ND病人在阅读过程中的表现,即衰减效应、词汇效应、词内区分效应、对称效应和词长效应以及保留的语义通达能力。尽管忽视症和ND可以分离,但两者之间有一定联系。文章最后对汉语ND的研究进行了分析和展望,认为其关键问题是阐明汉语ND在多大程度上与拼音文字ND具有可比性。     

面孔加工特异性的事件相关电位研究

采用事件相关电位方法,以面孔、汽车、鸟和椅子为刺激,在汽车搜索作业及分类判断作业两种条件下考察了N170面孔特异性效应。结果发现,面孔在两种条件下均引起明显不同于其余三类物体的N170。实验任务对汽车刺激有明显的影响,具体表现为：在搜索作业下,汽车N170有接近面孔N170的趋势,其波幅显著大于鸟、椅子N170的波幅;在分类作业中,则没有这种显著的差异。从而为证明存在面孔识别的特异性神经机制提供了证据。     

团体决策支持系统和团体讨论对团体决策的影响

通过模拟实验的方法,探讨了团体决策支持系统（GDSS）和团体讨论对团体决策的影响。以大学生为被试,运用小组决策任务,对小组决策过程进行了研究。实验记录了在有无GDSS的支持和有无团体讨论两个变量所决定的4种实验条件下,小组决策取得结果的正确性和组内的一致性。用ANOVA方法分析了4种条件下的实验结果,发现GDSS能提高团体决策的正确性,而团体讨论将有助于成员做出一个正确的、一致的决策     

中国人人格量表（QZPS）的编制过程与初步结果

旨在编制能够反映中国人人格结构特点的中国人人格量表（QZPS）。文中首先分析了直接采用或修订西方人格量表的问题和潜在危险,以及目前国内使用的各种人格量表存在的局限;按照人格研究的“词汇学假设”,根据杨国枢和王登峰（1999）以及后来的研究所确定的中国人人格结构的七因素模型,提出了QZPS的编制原则和操作程序。按照人格特质形容词的含义编写测量项目,并根据小因素和大因素的含义对项目进行修改,初步确定了1600多个项目。经2280名被试的评定,初步筛选出409个项目。再经1099名被试评定,确定了215个项目构成QZPS,测量中国人人格的7个维度和18个小因素。文中还报告了对QZPS的项目分析的结果
