This paper presents results of a National Science Foundation sponsored study to examine the financing of the leading 100 research universities. The study examines the changing dependence of these institutions on the federal government for overall financial support, the shifts in the concentration of federal funding to and within higher education, and the various programmatic and resource characteristics of these leading research institutions. The study covers five fiscal periods, 1975 through 1979.Presented at the Twenty First Annual Forum of The Association for Institutional Research, Minneapolis, May 1981. 相似文献

Two experiments tested two cynomolgus monkeys’ self-control—choice of a longer, more delayed reinforcer over a shorter, less delayed reinforcer. In Experiment 1, subjects exhibited significant selfcontrol in a procedure in which reinforcer amounts and delays were held constant throughout a condition. In Experiment 2, subjects exhibited significantly greater sensitivity to variation in reinforcer amount than to variation in reinforcer delay in a procedure in which the reinforcer delay associated with the self-control alternative was adjusted until each macaque was indifferent between the two alternatives. Both experiments indicated that, in laboratory paradigms in which humans show self-control and pigeons and rats show impulsiveness, macaques show self-control. These results are inconsistent with the hypothesis that species differences in self-control are a function of language ability or of specific types of prior training. The results are consistent with the hypothesis that species differences in self-control are related to the ratio of brain size to body weight (a possible indicator of general cognitive ability) or to shared phylogeny. 相似文献

Unidimensionality and local independence are two common assumptions of item response theory. The former implies that all items measure a common latent trait, while the latter implies that responses are independent, conditional on respondents’ location on the latent trait. Yet, few tests are truly unidimensional. Unmodeled dimensions may result in test items displaying dependencies, which can lead to misestimated parameters and inflated reliability estimates. In this article, we investigate the dimensionality of interim mathematics tests and evaluate the extent to which modeling minor dimensions in the data change model parameter estimates. We found evidence of minor dimensions, but parameter estimates across models were similar. Our results indicate that minor dimensions outside the primary trait have negligible consequences on parameter estimates. This finding was observed despite the ratio of multidimensional to unidimensional items being above previously recommended thresholds. 相似文献

This paper is concerned with the process of religious thinking as a linguistic form of investigating the world of values, which stands in contrast to theology and religious studies. It hinges around Wittgenstein’s comment, “I am not a religious man but I cannot help but see every question from a religious point of view.” It argues that scientific modes of thought are now so dominant that values education of all types are distorted as science itself was once distorted in an age when theological language held sway. The result today is the worrying growth of what is usually termed fundamentalism or literalism. The paper introduces the thinking on this issue from the curriculum theories of the Danish thinker Søren Kierkegaard, which have been ignored for nearly two centuries, before examining the work of a modern scholar, Christopher Arthur. Finally Whitehead’s insights arising from his later works are brought into play to conclude the argument. 相似文献

An initial outline of a cognitive schemata theory of self-instruction is presented. Three levels of schemata are described briefly. Attention then is devoted to the cognitive organization and operation of these schemata in relation to procedural and declarative knowledge stores, and in relation to everchanging situational information. The primary objective is to provide an initial basis for conceptualizing the cognitive competence required for self-instruction.Requests for reprints should be directed to Jack Martin, Associate Professor, at the above address. Work on this paper was begun while the author was an Associate Professor in the Faculty of Education at Simon Fraser University. 相似文献

MplusAutomation is a package for R that facilitates complex latent variable analyses in Mplus involving comparisons among many models and parameters. More specifically, MplusAutomation provides tools to accomplish 3 objectives: to create and manage Mplus syntax for groups of related models; to automate the estimation of many models; and to extract, aggregate, and compare fit statistics, parameter estimates, and ancillary model outputs. We provide an introduction to the package using applied examples including a large-scale simulation study. By reducing the effort required for large-scale studies, a broad goal of MplusAutomation is to support methodological developments in structural equation modeling using Mplus. 相似文献

Engineering Design is rightfully regarded as a key element within all university Engineering courses and most laboratory assignments and project work seek to optimise the student's acquisition of knowledge and understanding of this process. Within this paper Engineering Design has been classified into a new 'hierarchy of task level' each one defined by an increased degree of design freedom that an Engineer has to consider. It is argued that this classification accurately reflects the varying complexity of tasks found within real world industrial environment. The optimal matching of these task levels to university course assignments is discussed and limitations identified. The need for further design experience within a wider industrial context is shown to be essential if the nature of design freedom is to be fully appreciated by the next generation of professional Engineers. 相似文献
