Large sample properties of four methods of handling multivariate missing data are compared. The criterion for comparison is how well the loadings from a single factor model can be estimated. It is shown that efficiencies of the methods depend on the pattern or arrangement of missing data, and an evaluation study is used to generate predictive efficiency equations to guide one's choice of an estimating procedure. A simple regression-type estimator is introduced which shows high efficiency relative to the maximum likelihood method over a large range of patterns and covariance matrices. 相似文献

My aim in this paper is to examine a rational discovery strategy that I call “assimilation”, the attempt to understand a new domain by systematically interpreting the items it contains in terms of an established conceptual structure. The claim that this approach can lead to important new discoveries is illustrated by considering Galileo's attempt to develop a mathematical theory of the strength of materials and his discovery of mountains on the moon. 相似文献

The present research is an examination of the parameters and correlates of kanashibari, operationally defined as being unable to move upon awakening or before falling asleep. Nonclinical Japanese individuals (N = 720), 34% of whom reported an experience of kanashibari at least once, were administered D. I. Templer's (1970) Death Anxiety Scale, R. Brown's (1990) Locus of Control Scale, and a questionnaire devised by the authors to collect information about kanashibari. The results showed that the kanashibari experience was positively correlated with death anxiety, with being a woman, and with external-other locus of control; this last measure assessed the extent to which these individuals felt that their lives were determined by fate, good luck, or chance. 相似文献

We review the implications of recent ERP evidence for when and how grammatical gender agreement constrains sentence parsing. In some theories of parsing, gender is assumed to immediately and categorically block gender-incongruent phrase structure alternatives from being pursued. In other theories, the parser initially ignores gender altogether. The ERP evidence we discuss suggests an intermediate position, in which grammatical gender does not immediately block gender-incongruent phrase structures from being considered, but is used to dispose of them shortly thereafter. 相似文献

We assessed the immediate effects of two universal, first-grade preventive interventions on the proximal targets of poor achievement, concentration problems, aggression, and shy behaviors, known early risk behaviors for later substance use/abuse, affective disorder, and conduct disorder. The classroom-centered (CC) intervention was designed to reduce these early risk behaviors by enhancing teachers' behavior management and instructional skills, whereas the family-school partnership (FSP) intervention was aimed at improving parent-teacher communication and parental teaching and child behavior management strategies. Over the course of first and second grades, the CC intervention yielded the greatest degree of impact on its proximal targets, whereas the FSP's impact was somewhat less. The effects were influenced by gender and by preintervention levels of risk. Analyses of implementation measures demonstrated that greater fidelity to the intervention protocols was associated with greater impact on behavior ratings and on achievement scores, thus providing some evidence of specificity in the effect of the interventions. 相似文献

Recent developments have raised questions about the distinctiveness of guidance and whether its practice can be separated from that of related professions. Those developments are reviewed. It is suggested that a distinctive position may be found by an examination of certain key features of guidance practice. One of these features is the role of information. Information is distinguished from informing. Its nature is discussed, as is its use in practice by both clients and guidance practitioners. 相似文献

Behavioural context is known to affect neural activity in the striatum. Responses of single cells increase to rewarding stimuli, or drop out as a bar press or saccade is learned. Networks that can accomplish a unique response to changing contexts are of particular interest to systems neuroscience and were a part of Hebb's interest in perception and learning. An overall map of the striatum that localizes changes related to this remarkable phenomenon of contextual responses contributes to our understanding of anatomical substrates of neural systems that integrate information, and may lead us to new striatal regions to study synaptic mechanisms of learning. 相似文献
