Word stress production in three‐year‐old children at risk of dyslexia     

Elise De Bree  Frank Wijnen  Wim Zonneveld 《Journal of Research in Reading》2006,29(3):304-317

We investigated Dutch word stress acquisition in 3‐year‐old children at risk of dyslexia (children with at least one parent or older sibling with reading difficulties) and normally developing children, in order to shed light on language acquisition delays in children at risk of dyslexia, as well as to investigate further phonological deficits in dyslexia. The children had to repeat non‐words with stress patterns varying in regularity. Both the at‐risk and control children performed better on imitation of regular stress targets and worse on irregular and prohibited stress patterns. However, the at‐risk children showed more difficulty imitating irregular and prohibited patterns, and had lower percentages phonemes correct than the control group. The results can be interpreted as a delay in word stress acquisition in the at‐risk group. The findings thus point towards a phonological deficit early in language development.  相似文献   

Assumptions Underlying Performance-Based Budgeting     

Frank A. Schmidtlein 《Tertiary Education and Management》1999,5(2):157-172

Interest in performance budgeting is growing despite a lack of research on its effectiveness. U.S. states have largely used incremental and formula budgeting processes to fund higher education. However, more than half of them are experimenting with some form of performance budgeting. There have been similar attempts to reform budget practices in the U.S. in the past, but most of these processes have been largely abandoned. Governmental performance budgeting for higher education assumes policy objectives are stable, complex decisions on budget trade-offs can be made at governmental levels on the basis of data, institutions operate as bureaucracies, resources can be linked to outcomes, outcomes are identifiable and can be agreed upon, accountability can be achieved through budget policies, and current practices create incentives to enrol unqualified students. These assumptions are not realistic. Consequently, performance budgeting will not meet proponents expectations and will suffer the fate of past budget fads.  相似文献   

A theoretical note on concepts and the need for Cyclic Concept Maps     

Frank Safayeni  Natalia Derbentseva  Alberto J. Caas 《科学教学研究杂志》2005,42(7):741-766

This article examines concepts and propositions from a theoretical perspective, and establishes the need for and develops an extension to Concept Maps (CMaps), called Cyclic Concept Maps (Cyclic CMaps). Cyclic CMaps are considered to be an appropriate tool for representing knowledge of functional or dynamical relationships between concepts. CMaps, on the other hand, are viewed as an appropriate tool for representing hierarchic or static knowledge. The two maps complement each other and collectively capture a larger domain of knowledge, thus forming a more effective knowledge representation tool. © 2005 Wiley Periodicals, Inc.

K S Krishnan’s 1948 perception of the sampling theorem     

Rajiah Simon 《Resonance》2002,7(2):20-25

K S Krishnan discovered in 1948 that the sum over samples of a band-limited function gives the value of the integral of the function exactly, provided the sampling interval does not exceed a threshold value. This result of Krishnan is shown to be equivalent to the Shannon sampling theorem.  相似文献   

Behavioral and Electrophysiological Evidence for Gestational Age Effects in Healthy Preterm and Fullterm Infants Studied Two Weeks after Expected Due Date   总被引：2，自引：0，他引：2  

Frank H. Duffy  Heidelise Als  Gloria B. McAnulty 《Child development》1990,61(4):1271-1286

We investigated the effects of gestational age at birth on behavioral and electrophysiological measures of 135 medically healthy infants, studied at 42 weeks postconception, and stratified into 3 groups--early-born preterms, 26-32 weeks (n = 55); middle-group preterms, 33-37 weeks (n = 43); and fullterms, 38-41 weeks (n = 37). Subjects were studied behaviorally with the Assessment of Preterm Infants' Behavior (APIB) and electrophysiologically with brain electrical activity mapping (BEAM). Fullterms showed significantly better behavioral function than both preterm groups. Less difference was found between the preterm groups. EEG spectral and photic evoked response were of significantly less amplitude for the preterms than the fullterms. Path analysis showed gestational age effects on behavioral (3 of 6) and electrophysiological (13 of 17) variables due to postnatal complications. We conclude that some differences attributable to gestational age at birth are explained by the cumulative effect of minor but unavoidable complications associated with premature birth. We speculate that remaining effects may result from developmentally inappropriate sensorimotor stimulation consequent to the premature experience of an extrauterine environment.  相似文献

Correspondence Training as a Means of Improving Study Skills     

Jonathan Merrett  Frank Merrett 《教育心理学》1997,17(4):469-482

This study was an attempt to encourage middle school pupils to use time spent on topic (project) work to better effect. They were taught some elements of correspondence training which required them to think ahead, to plan carefully what they were going to do in a certain time period and to make a forecast. At the end of each working session, they were required to look back at what they had achieved and to discuss the outcomes with a partner in terms of their success at forecasting and in achievement. Especially among the more able pupils, there were marked improvements in both quantity and quality of work produced  相似文献   

Domain Coloring and the Argument Principle     

Frank A. Farris 《PRIMUS》2017,27(8-9):827-844

Abstract

The domain-coloring algorithm allows us to visualize complex-valued functions on the plane in a single image—an alternative to before-and-after mapping diagrams. It helps us see when a function is analytic and aids in understanding contour integrals. The culmination of this article is a visual discovery and subsequent proof of the Argument Principle, which relates the count of poles and zeros of a meromorphic function inside a contour to the accumulated change in argument of the function around the contour. Throughout, I offer connections to standard learning goals of courses in complex variables.  相似文献
