Four measurement designs are presented for use with correlation coefficients corrected, in one variable, for attenuation due to unreliability—coefficients that we term partially disattenuated correlation coefficients. Asymptotic expressions are derived for the variances and covariances of the estimates accompanying each design. Empirical simulation results that bear on the preceding mathematical developments are then presented. In addition to providing insights into the distributions of the estimates, the empirical results demonstrate satisfactory Type I error control for typical inferential applications. Power is shown to be equal to or greater than that of corresponding product-moment correlations in three of the four designs. Implications for practice are discussed.Support for the research reported in this article was provided by the Natural Sciences and Engineering Research Council of Canada. The authors acknowledge with thanks the contributions of Nancy E. Heckman to some of the theoretical aspects of the study. 相似文献

In this article an overview is given of personality research related to the temperamental system of the Dutch philosopher and psychologist Gerard Heymans (1852–1930). After a sketch of this three-dimensional typology, three domains of research are briefly described. The first is a line of research on the system itself and its applications in differential psychology. In the second, the role of its dimensions in modern trait psychology is sketched. In the third line of thought the Heymans categories are viewed and investigated as dimensions of person perception. 相似文献

In this paper, I ponder the question of whether Socrates follows a method of investigation — the method of hypothesis — which he advocates in Plato's Phaedo. The evidence in the dialogue suggests that he does not follow the method, which raises additional questions: If he fails to do so, why does he articulate the method? Does his statement of method affect his actions or is it mainly forgotten? Although Socrates is a fictional character, his actions in the Phaedo suggests questions about the function of espoused methods in actual situations. 相似文献

Seven-, ten-, and thirteen-year-old learning-disabled (LD) and non-learning-disabled (NORM) children were presented specially structured lists of 38 words each and tested for free recall. Each list contained only four semantically related words. Two of the four related words were presented contiguously (serial positions 9 and 10) and the other two words were spaced (serial positions 20 and 30). All children recalled disproportionately more adjacent words (item 9 or 10) than any other words. Spaced words (items 20 and 30) were less likely to be recalled by the younger children than by the older children and by the LDs than by the NORMS. These findings provided support for the distinction between automatic and purposive semantic processing. NORMs' recall was governed by purposive semantic processing to a greater extent than was LDs' recall. However, no group or age differences were observed in automatic semantic processing. 相似文献

The method proposed by Harman and Fukuda to treat the so-called Heywood case in the minres method in factor analysis i.e., the case where the resulting communalities are greater than one, involves the frequent solution of eigenvalue problems. A simple method to treat this problem requiring less computing time and enjoying higher numerical stability is described in this paper. 相似文献

Generalized bilinear models are presented for the statistical analysis of two-way arrays. These models combine bilinear models and generalized linear modeling, and yield a family of models that includes many existing models, as well as suggest other potentially useful ones. This approach both unifies and extends models for two-way arrays, including the ability to treat response and explanatory variables differently in the models, and the incorporation of external information about the variables directly into the analysis. A unifying framework for the generalized bilinear models is provided by considering four particular cases which have been proposed and used in the existing statistical literature. A three-step procedure is proposed to analyze data sets by generalized bilinear models. Two data sets of different nature are analyzed. 相似文献

A one-way random effects model for trimmed means 总被引:1,自引:0,他引:1
Rand R. Wilcox 《Psychometrika》1994,59(3):289-306
The random effects ANOVA model plays an important role in many psychological studies, but the usual model suffers from at least two serious problems. The first is that even under normality, violating the assumption of equal variances can have serious consequences in terms of Type I errors or significance levels, and it can affect power as well. The second and perhaps more serious concern is that even slight departures from normality can result in a substantial loss of power when testing hypotheses. Jeyaratnam and Othman (1985) proposed a method for handling unequal variances, under the assumption of normality, but no results were given on how their procedure performs when distributions are nonnormal. A secondary goal in this paper is to address this issue via simulations. As will be seen, problems arise with both Type I errors and power. Another secondary goal is to provide new simulation results on the Rust-Fligner modification of the Kruskal-Wallis test. The primary goal is to propose a generalization of the usual random effects model based on trimmed means. The resulting test of no differences among J randomly sampled groups has certain advantages in terms of Type I errors, and it can yield substantial gains in power when distributions have heavy tails and outliers. This last feature is very important in applied work because recent investigations indicate that heavy-tailed distributions are common. Included is a suggestion for a heteroscedastic Winsorized analog of the usual intraclass correlation coefficient. 相似文献

Abstract. Evolution has become the standard way of understanding the world process. Theology has to express traditional faith in the context of the contemporary world. Since the common world view has profoundly changed, from a static world of being into a dynamic world of becoming, theology needs to change its language and its understanding of the universe as God's creation. This understanding of an evolving world is to be used as a theological source. Such a change of perspective necessitates a fundamental reconstructing of theology; for theology, such reconstructing means a renewed understanding of the Creator and of the Incarnation. 相似文献

This essay argues that Aristotle's categories of oratory are not as useful in judging the methods of Sophistical rhetoric as his presentation of time. The Sophistical argumentative method of making the weaker the stronger case is re-evaluated as a political practice. After showing this argument's relation to power and ideology, Aristotle's philosophy, which privileges a procedure of argument consistent with the politics of a polis-ideal rhetoric, is offered as reason for objecting to Sophistical rhetoric. The essay concludes that Sophistical rhetoric prefers the concept of possibility over Aristotelian actuality, and offers a need for an ideological space of radical, generative possibility in rhetorical theory. 相似文献

论中医的科学精神和人文方法 总被引:18,自引:4,他引:14

近十几年来中医现代化研究成效不显,以及发生许许多多的争论和困惑的重要原因在于我们对中医的基本性质缺乏一种共识。说中医就是一门科学或者不是科学,是一门经验医学或者是哲学医都会使我们陷于一个难堪的困境。中医具有科学精神,但不具有西方意义上的科学方法,而是用具有中国特色的人文方法实现科学精神的经验知识体系。具有科学精神是一回事,怎样实现这种精神却是另一回事,前者是无国界的,后者却是可以文化多元的。 相似文献
