INCREASING HABILITATIVE SERVICES FOR PERSONS WITH PROFOUND HANDICAPS: AN APPLICATION OF STRUCTURAL ANALYSIS TO STAFF MANAGEMENT

We evaluated a structural analysis methodology for enhancing the utility of a staff management program. In Experiment 1, a structural analysis of direct-care staff behavior in a mental retardation facility revealed differences in work patterns over time. Specific times were identified when few basic care duties were necessary and staff engaged in nonwork activity. In Experiment 2, a management program was implemented to increase staff members' training activities during periods identified through the structural analysis. The program was accompanied by increases in training activities and decreases in nonwork behavior. The improvements were maintained during a 43-week period while the most labor-intensive component of the program was withdrawn. Staff acceptability measures indicated a positive response to the management intervention, although responses varied across components within the multifaceted program. The increased training was accompanied by beneficial changes among clients with profound handicaps. Results are discussed regarding practical considerations for improving staff performance and for adopting innovations resulting from applied research.     

On Keats' generalization of the rasch model

Parameter estimation for Keats generalization of the Rasch model that takes account of guessing behavior is investigated. It is shown that no minimal sufficient statistics for the ability parameters independent of the difficulty parameters exist. Thus Andersen's conditional inference technique for consistent estimation is not applicable to Keats' model. The notion of separability of the parameters is generalized.     

Multivariate analysis with linearizable regressions

We study the class of multivariate distributions in which all bivariate regressions can be linearized by separate transformation of each of the variables. This class seems more realistic than the multivariate normal or the elliptical distributions, and at the same time its study allows us to combine the results from multivariate analysis with optimal scaling and classical multivariate analysis. In particular a two-stage procedure which first scales the variables optimally, and then fits a simultaneous equations model, is studied in detail and is shown to have some desirable properties.     

Measurement error and ANCOVA: Functional and structural relationship approaches

This article discusses alternative procedures to the standardF-test for ANCOVA in case the covariate is measured with error. Both a functional and a structural relationship approach are described. Examples of both types of analysis are given for the simple two-group design. Several cases are discussed and special attention is given to issues of model identifiability. An approximate statistical test based on the functional relationship approach is described. On the basis of Monte Carlo simulation results it is concluded that this testing procedure is to be preferred to the conventionalF-test of the ANCOVA null hypothesis. It is shown how the standard null hypothesis may be tested in a structural relationship approach. It is concluded that some knowledge of the reliability of the covariate is necessary in order to obtain meaningful results.     

Syntactic Priming: A Corpus-based Approach

The present study is a corpus-based investigation of syntactic priming, i.e. the tendency to reuse syntactic constructions. On the basis of data from the ICE-GB corpus, I analyze two different pairs of syntactic patterns, the so-called dative alternation and particle placement of transitive phrasal verbs. Although it has sometimes been argued that only experimental data can contribute to studies of priming, the analysis shows that (a) the corpus-based results for datives are very similar to the experimental ones; (b) priming is also obtained for the verb-particle construction, a construction hitherto not explored in the priming literature and (c), most importantly, in line with much previous psycholinguistic and corpus-linguistic work, priming effects turn out to be strongly verb-specific such that some verbs are much more resistant or responsive to priming than others. I conclude with a discussion of how corpus data relate to experimental data and how the corpus-based findings can contribute to psycholinguistic model building.This paper is dedicated to Günter Rohdenburg on the occasion of his 65th birthday I thank (in alphabetical order) Doris Schönefeld (Ruhr University of Bochum), Anja Steinlen (University of Southern Denmark) and Stefanie Wulff (University of Bremen) for comments on a previous draft of this paper. In addition, I have benefited a lot from discussion with Benedikt Szmrecsanyi (University of Freiburg) and from the very detailed and useful comments of one anonymous reviewer, which made it possible to improve the paper considerably. Naturally, all remaining inadequacies are my own.     

Paradox explored: Climate shame,moral agency,the church,and the birds

This article explores shame and moral agency in relationship to the climate catastrophe, and the moral situation of the world's relatively high-consuming people who are implicated in greenhouse gas emissions that cause climate change. The author complexifies that situation in the conundrums of climate colonialism, climate racism, structural sin, and the moral ambiguities they raise, including such questions as: “What are the moral demands of climate sin grounded in historically rooted economic systems that one did not create but upon which the material conditions of one's life depend? To what extent, if any, is the individual morally accountable for the social structures of which one is a part and from which one benefits?” From there, the essay moves to its central question. It is whether shame theory might help to enable moral agency for what is desperately needed now by people of climate privilege and economic privilege in the North Atlantic world—wise and courageous action to address climate change and climate injustice. The article probes shame theory for clues to what disables moral agency and what catalyzes it. The author finds in shame theory pathways for transforming shame-based moral inertia into moral agency. Those pathways suggest vital roles for the church.     

Structural linguistic injustice

This paper develops a concept of structural linguistic injustice. By employing the so-called structural-injustice approach, it argues that individuals' seemingly harmless language attitudes and language choices might enable serious harms on a collective level, constituting what one could call a structural linguistic injustice. Section 1 introduces the linguistic-justice debate. By doing so, it establishes linguistic diversity as the context in which phenomena such as individuals' language attitudes, language choice, and language loss occur. Moreover, the paper illustrates why employing the structural-injustice approach might be beneficial for the linguistic-justice debate. Section 2 conceptualizes individuals' (certain types of) language attitudes and language choice as (objectionable) social structures. Section 3 provides a concept of structural linguistic injustice. Section 4 suggests one possible remedy for structural linguistic injustice. Section 5 concludes the paper.     

小鼠的记忆与脑内突触结构参数变化的相关性

比较不同月龄小鼠学习记忆力与脑内突触结构参数变化的相关性。选用１月龄和６月龄小鼠,用Ｙ－迷宫检测分辨学习能力,用一次性被动回避反应检测记忆力。然后杀鼠取脑,进行超微结构观察和定量分析测定。结果表明：（１）１月龄小鼠的分辨学习能力优于６月龄小鼠,记忆力也有优于６月龄小鼠的趋势。（２）无论在海马或大脑皮层体区,有两种结构参数有一致性增龄变化,即６月龄小鼠突触界面曲率都比１月龄小鼠显著和极显著增大;而６月龄小鼠上述两脑区的突触后致密物质厚度都极显著地小于１月龄小鼠。实验结果提示,脑内突触界面结构的增龄性变化可能是学习记忆力增龄性变化的结构基础。     

Stability of aggression among adolescents over time: A south African study

In a study spanning 5 years, data were collected on the aggressiveness of over 1,700 male and female subjects. Subjects who were the more aggressive grade 8 (standard 6) pupils at the beginning of the study were discovered to be the more aggressive grade 12 (standard 10) pupils. It is concluded that, whatever its causes, aggression can be viewed as a persistent trait that may be influenced by situational variables but reveals substantial consistency over time. The findings of studies by Huesmann and Eron in the United States as well as Olweus in Scandinavia were thus supported in this South African investigation.     

一种新的统计方法和研究思路——结构方程建模述评

结构方程建模(SEM)是一种新的统计方法和研究思路,近年来在心理学和社会科学领域的应用日益增多。本文在非数学化的基础上,结合心理学研究实例介绍了SEM的渊源、发展、基本概念、分析过程以及相应的计算机统计软件LI-SREL。本文认为SEM有四大优点:①引进潜变量使研究更为深入,②遵循一般线性模式进行验证型分析,使研究更有意义,③妥善处理多变量间的复杂关系,④模型具有参数不变性。SEM应该引起国内心理学界的重视。
