The statistical simulation program DATASIM is designed to conduct large-scale sampling experiments on microcomputers. Monte Carlo procedures are used to investigate the Type I and Type II error rates for statistical tests when one or more assumptions are systematically violated-assumptions, for example, regarding normality, homogeneity of variance or covariance, mini-mum expected cell frequencies, and the like. In the present paper, we report several initial tests of the data-generating algorithms employed by DATASIM. The results indicate that the uniform and standard normal deviate generators perform satisfactorily. Furthermore, Kolmogorov-Smirnov tests show that the sampling distributions ofz, t, F, χ2, andr generated by DATASIM simulations follow the appropriate theoretical distributions. Finally, estimates of Type I error rates obtained by DATASIM under various patterns of violations of assumptions are in close agreement with the results of previous analytical and empirical studies; These converging lines of evidence suggest that DATASIM may well prove to be a reliable and productive tool for conducting statistical simulation research. 相似文献

Although consultation researchers and practitioners have called attention to the need for more psychometrically sound instruments, little advancement has occurred in this area. The authors outline key quantitative and qualitative psychometric standards for organizational consultation assessment and evaluation instruments. In addition, a framework and review of several existing questionnaires are presented. Implications for instrument use by practitioners and suggestions for further research are discussed. 相似文献

There is a growing concern for quality care in residential placements outside of the natural family for children and youth with developmental disabilities. Ideally, children with developmental disabilities should remain with their natural parent or parents of parents with appropriate supports until the age when children typically leave home. In reality, parents of children and youth with development disabilities are not always able or willing to care for their children at home, and alternate residential placements must be found. This paper will discuss some of the issues surrounding the provision of quality care in out-of-home residential placements for children and youth with developmental disabilities. 相似文献

This study is a replication of the 1972 study Dick and Jane as Victims done by Women on Words and Images. The original study examined 134 children's readers, and found sex stereotyping in both number of times males and females appeared, and the activities in which they were shown. The replication is a content analysis of 62 children's readers in use in 1989 to determine if males and females were still shown in sex-stereotyped roles. It was found that although there are still differences in the rate of portrayal for males and females, and in the variety of roles assigned to each, the differences are not as pronounced as they were in 1972. 相似文献

A technique is described for rapidly collecting responses in auditory-localization experiments. Subjects indicate the perceived direction of the sound by pointing at a 20-cm-diam spherical model. In Experiment 1, the subjects judged the direction of a broadband signal, which could originate from any of 239 directions ranging through 360° of azimuth and between ?45° and +90° of elevation. Using this technique, the subjects responded 2–8 times more rapidly than previous subjects who used either a verbal-reporting technique or a head-pointing technique. Localization judgments were as accurate as they had been with verbal reports, but were not as accurate as judgments collected using the head-pointing technique. In Experiment 2, the signal was turned off and the experimenter read the spherical coordinates of the signal location to the subjects. The subjects pointed to these coordinates more accurately than they had judged the direction of the sounds in Experiment 1, suggesting that the response technique had not been the limiting factor in that experiment. Circumstances relevant to the choice of response techniques for auditory-localization experiments are discussed. 相似文献

This study of female and male undergraduate business majors explored the relationship of their preferred future career-marriage arrangement to their relationship and work values, work motivation, and gender role orientation Results indicate that the dual-career, career-job, and career-home groups showed significant differences on these dimensions. Additionally, sex and gender role differences reflected cultural stereotypes of achievement orientation in men and barriers to career pursuits of women. The results are discussed in terms of interpersonal, intrapersonal, and societal factors underlying career-marriage aspirations. Implications for practitioners and suggestions for future research are given. 相似文献

In this comment, I examine Amsel’s theory in the light of rats’ reaction not to frustrative non-reward per se, but to the more complicated case in which frustrative nonreward is part of a rule-based sequence of reward quantities. The discussion goes beyond Amsel’s emphasis on dispositional memory to consider cognitive and representational memory—the signaling properties of reinforcement and nonreinforcement. The strengths and weaknesses of Amsel’s theory are discussed with the fresh perspective that this viewpoint provides, and some issues emerge that may be fruitful for further study. 相似文献

The study included 17 patients, 12 women and 5 men, with a recurrent symptom complex involving chest pain and dyspnoea characterized
by inability to get a full breath. Some attacks had subsided spontaneously. Others had lasted hours or days. When examined
by fluoroscopy during an attack, each subject was found to have a nearly maximally contracted (flat) diaphragm. In some of
them the attack was promptly interrupted by a small intravenous injection of sodium amytal. In others it could be aborted
by a conscious effort at full expiration. The syndrome associated with diaphragmatic spasm is discussed in comparison with
other noncardiac sources of chest pain and dyspnoea. 相似文献
