Estimating the standard errors of rotated factor loadings by jackknifing

The jackknife by groups and modifications of the jackknife by groups are used to estimate standard errors of rotated factor loadings for selected populations in common factor model maximum likelihood factor analysis. Simulations are performed in whicht-statistics based upon these jackknife estimates of the standard errors are computed. The validity of thet-statistics and their associated confidence intervals is assessed. Methods are given through which the computational efficiency of the jackknife may be greatly enhanced in the factor analysis model.Computing assistance was obtained from the Health Sciences Computing Facility, UCLA, sponsored by NIH Special Research Resources Grant RR-3.The author wishes to thank his doctoral committee co-chairmen, Drs James W.

Estimation of covariance structure models with parameters subject to functional restraints

This paper demonstrates the feasibility of using the penalty function method to estimate parameters that are subject to a set of functional constraints in covariance structure analysis. Both types of inequality and equality constraints are studied. The approaches of maximum likelihood and generalized least squares estimation are considered. A modified Scoring algorithm and a modified Gauss-Newton algorithm are implemented to produce the appropriate constrained estimates. The methodology is illustrated by its applications to Heywood cases in confirmatory factor analysis, quasi-Weiner simplex model, and multitrait-multimethod matrix analysis.The author is indebted to several anonymous reviewers for creative suggestions for improvement of this paper.

A feasible method for standard errors of estimate in maximum likelihood factor analysis

A jackknife-like procedure is developed for producing standard errors of estimate in maximum likelihood factor analysis. Unlike earlier methods based on information theory, the procedure developed is computationally feasible on larger problems. Unlike earlier methods based on the jackknife, the present procedure is not plagued by the factor alignment problem, the Heywood case problem, or the necessity to jackknife by groups. Standard errors may be produced for rotated and unrotated loading estimates using either orthogonal or oblique rotation as well as for estimates of unique factor variances and common factor correlations. The total cost for larger problems is a small multiple of the square of the number of variables times the number of observations used in the analysis. Examples are given to demonstrate the feasibility of the method.The research done by R. I. Jennrich was supported in part by NSF Grant MCS 77-02121. The research done by D. B.

Critiques of Casuistry and Why They Are Mistaken

Casuistic methods of reasoning in medical ethics have been criticized by a number of authors. At least five main objections to casuistry have been put forward: (1) it requires a uniformity of views that is not present in contemporary pluralistic society; (2) it cannot achieve consensus on controversial issues; (3) it is unable to examine critically intuitions about cases; (4) it yields different conclusions about cases when alternative paradigms are chosen; and (5) it cannot articulate the grounds of its conclusions. Two main versions of casuistry have been put forward, and the responses to these objections depend in part on which version one is defending. Jonsen has advocated a version modeled on the approach to casuistry used by moral theologians in the 15th and 16th century, involving comparison of the case at hand with a single paradigm and a lineup of cases. The present author has advocated another version, drawn from experience with cases in clinical ethics, which involves comparing the case at hand with two or more paradigms. Four of the five objections are unsuccessful when directed against Jonsen'sapproach, and all of them are unsuccessful when directed against the approach involving comparison with two or more paradigms.     

基于模式分类的中医医案分析技术

中医药经历数千年的发展,已积累了大量数据,特别是从古到今的医案数据,但这些数据因没有用现代信息手段整理、分析,而不能为中医药的科学研究提供支持。本文将模式分类技术应用于医案数据的分析中,从已知的病症推断出所属的证型。该方法能够进行自动学习,不需要专家的辅助即可从医案中学习到病症和证型的联系。     

Nonlinear Bayesian analysis for single case designs

Several authors have suggested the use of multilevel models for the analysis of data from single case designs. Multilevel models are a logical approach to analyzing such data, and deal well with the possible different time points and treatment phases for different subjects. However, they are limited in several ways that are addressed by Bayesian methods. For small samples Bayesian methods fully take into account uncertainty in random effects when estimating fixed effects; the computational methods now in use can fit complex models that represent accurately the behavior being modeled; groups of parameters can be more accurately estimated with shrinkage methods; prior information can be included; and interpretation is more straightforward. The computer programs for Bayesian analysis allow many (nonstandard) nonlinear models to be fit; an example using floor and ceiling effects is discussed here.

两种训练方法对幼儿在园欺负行为的影响

该研究为了减少幼儿在园欺负行为,采用情境讨论法、角色扮演法对36名中班幼儿和39名大班幼儿的欺负行为进行为期一个月的训练.结果发现:角色扮演法和情境讨论法对减少幼儿的在园欺负行为都产生了一定的影响,但角色扮演法对幼儿在园欺负行为的影响效果显著,而情境讨论法的影响效果不显著,同时这两种训练方法的影响效果之间无显著性差异;训练对中班和大班幼儿的欺负行为都起到了一定的矫正作用,中班幼儿的在园欺负行为下降水平略高于大班幼儿,但并没有达到显著性差异;训练对减少中班男生和大班女生的在园欺负行为更有效果.     

Where the Whole Thing Fell Apart

Abstract

This article examines the intersection of societal prejudice and psychological trauma. In an instrumental case study created through a layered narrative analysis, the author highlights the potentially traumatic effects of racism and discrimination, while also exploring the phenomenon of resilience in a complex ecological system. The findings suggest that the enduring and continual strain of racial prejudice may cause significant psychological distress, particularly when those experiences reinforce early negative experiences within a family; and that assessments of resilience need to consider the contribution of ecological context to psychological outcomes as well as to an individual's ability to mobilize personal resources when such a context finally shifts.     

Buddhist Perspectives for Addressing Values Conflicts in Counseling: Possibilities From Practice

In recent years, the issue of value conflicts in counseling has become more salient, whereas equitably working with such conflicts has been increasingly contested. Interest in the confluence of counseling and spirituality has also grown. Using relevant Buddhist principles, the authors offer a spiritual framework that is illustrated through clinical case studies. These are used to conceptualize concerns, understand the conflict, and find ways to be responsive to the disjunction between client and counselor.
