Best linear prediction of composite universe scores

The problem of predicting universe scores for samples of examinees based on their responses to samples of items is treated. A general measurement procedure is described in which multiple test forms are developed from a table of specifications and each form is administered to a different sample of examinees. The measurement model categorizes items according to the cells of such a table, and the linear function derived for minimizing error variance in prediction uses responses to these categories. In addition, some distinctions are drawn between aspects of the approach taken here and the familiar regressed score estimates.The author thanks Robert L. Brennan, Michael J.

脑梗死不同病因亚型同血浆同型半胱氨酸浓度的关系研究

为探讨脑梗死患者血浆同型半胱氨酸（HCY）水平同病因分型及疾病严重程度的关系,选择首发脑梗死急性期患者73例,对照组30例,进行TOAST病因分型、NIHSS神经功能缺损评分、血浆HCY检测。结果显示,病例组血浆HCY升高率、水平比对照组显著增高;大动脉粥样硬化亚型病例组血浆HCY水平比对照组明显增高;病例组血浆HCY水平同NIHSS评分呈正相关,提示高HCY血症是脑梗死发病及大动脉粥样硬化亚型脑梗死发病的高危因素,血浆HCY水平同神经功能缺损程度正相关。     

Acceptability in France of Induced Abortion for Adolescents

Background: This study investigated the factors affecting the acceptability in France of abortions. Method: 80 study participants from Toulouse and 124 from Metz judged the acceptability of abortion in 64 vignettes composed of five factors: 1) the adolescent's age (15 or 17.5 years), 2) the adolescent's plans to continue schooling or not, 3) the fetus' age (1, 2, 3, or 4 months), 4) the adolescent's parents' agreement or not, and 5) the agreement or not of baby's father. Results: Three clusters were noted: 1) abortion is never acceptable (8% of participants), 2) abortion is always acceptable (23%), and 3) acceptability of abortion depends on the circumstances (63%). In the majority cluster (3), all five factors had significant effects, but the fetus's age accounted for most of the variance (78%). Conclusion: Most subjects in this study judged, in accordance with French law, that the acceptability of induced abortion in minors depends on the circumstances and, in particular, on the fetus' age.     

Treating Self-Injurious Behavior:

The present study attempted to investigate the effects and possible side effects of a response cost and DRO treatment procedure on a subject's self-injurious behavior. Additionally, a number of staff management strategies were evaluated as to their effect on the maintenance of the behavior change. Finally, the acceptability of the treatment utilized was subjectively evaluated. Implications for designing maintenance strategies that are effective, feasible and acceptable are discussed.     

Some reflections on the origin of hate between man and woman

There is no love without hate and no hate without love; their opposite is indifference. According to Winnicott, human being’s deepest guilt evolves when his hate is stronger than his love. This paper will explore how the origin of hate may lie in early helplessness, in the difference between sexes and disturbances of developmental phases. Finally, it will be illustrated how hate can protect love in a relationship between man and woman.     

Use of Brief Experimental Analyses in Outpatient Clinic and Home Settings

We describe the historic and current use of brief experimental analysis procedures in outpatient clinic and home settings. We discuss some applications of the designs and suggest design modifications for improving internal validity. We describe our application of the designs to longitudinal, in-home programs for children with severe behavior disorders and demonstrate how related versions of brief experimental analysis procedures can be linked to form a more comprehensive evaluation.     

Effects of idiosyncratic stimulus variables on functional analysis outcomes.

As the methods for the functional analysis of problem behavior have continued to develop, there has been a greater focus on the specificity of controlling variables, both antecedents and consequences. Accelerating research interest in the role of antecedents reveals that a large array of stimulus variables can influence the rate of problem behavior. Indeed, the variety of these stimuli is so great that it is sometimes possible to overlook specific stimulus variables during initial assessment. The present study shows that a failure to identify these very specific (idiosyncratic) stimulus variables is serious because their presence can systematically alter the outcomes of functional analyses that are designed to assess the motivation of problem behavior. Guidelines are therefore discussed concerning when to suspect that idiosyncratic stimuli might be acting to influence assessment data, thereby promoting a search for additional stimulus variables whose identification can aid in improving the design of functional analysis conditions.     

Effects of Auditory Feedback on Movement Time in a Fitts Task

The purpose of the present experiment was to investigate the role of auditory feedback and its impact on movement time in a standard Fitts task. Feedback was given at the moment of target acquisition. A 2-way analysis of variance found significant differences between feedback groups at all three indexes of difficulty (F(2, 40) = 156.02, p < .001). Results from a mixed-model multivariate analysis of variance for kinematic factors show significant differences in peak velocity and the location of peak velocity when comparing feedback groups. In general, the addition of auditory feedback decreased the task ID by .5.
