National testing for college and university: The role of the Service for Admission to College and University (SACU) in Canadian higher education     

Vincent R. D'oyley  Hermann Müller-Solger 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1975,21(1):91-109

Taking the present crisis of the Canadian Service of Admission to College and University as a starting point, the authors examine the history of SACU, which in 1971 was still a comparatively efficient organisation. Changes in the wider society, such as growing provincialism in Canada as well as stagnation or decline in enrolment together with a broader acceptance of the philosophy of open admission, have led to a drastic decline in the number of participants in the tests and to severe criticism of the predominantly selective function of SACU. It is felt that a reorientation of the testing activities of SACU should be in the direction of distributive and counselling functions, thus adopting the 1970 recommendations of the Commission on Tests of the American College Entrance Examination Board.  相似文献   

A tapered channel microfluidic device for comprehensive cell adhesion analysis, using measurements of detachment kinetics and shear stress-dependent motion     

Rupprecht P  Golé L  Rieu JP  Vézy C  Ferrigno R  Mertani HC  Rivière C 《Biomicrofluidics》2012,6(1):14107-1410712

We have developed a method for studying cellular adhesion by using a custom-designed microfluidic device with parallel non-connected tapered channels. The design enables investigation of cellular responses to a large range of shear stress (ratio of 25) with a single input flow-rate. For each shear stress, a large number of cells are analyzed (500–1500 cells), providing statistically relevant data within a single experiment. Besides adhesion strength measurements, the microsystem presented in this paper enables in-depth analysis of cell detachment kinetics by real-time videomicroscopy. It offers the possibility to analyze adhesion-associated processes, such as migration or cell shape change, within the same experiment. To show the versatility of our device, we examined quantitatively cell adhesion by analyzing kinetics, adhesive strength and migration behaviour or cell shape modifications of the unicellular model cell organism Dictyostelium discoideum at 21 °C and of the human breast cancer cell line MDA-MB-231 at 37 °C. For both cell types, we found that the threshold stresses, which are necessary to detach the cells, follow lognormal distributions, and that the detachment process follows first order kinetics. In addition, for particular conditions’ cells are found to exhibit similar adhesion threshold stresses, but very different detachment kinetics, revealing the importance of dynamics analysis to fully describe cell adhesion. With its rapid implementation and potential for parallel sample processing, such microsystem offers a highly controllable platform for exploring cell adhesion characteristics in a large set of environmental conditions and cell types, and could have wide applications across cell biology, tissue engineering, and cell screening.  相似文献   

Influence of a conservative sleep management strategy during a solo Pacific Ocean crossing on anxiety and perceived fatigue: a case study     

Hagin V  Gonzales BR  Candau RB  Groslambert A 《Journal of sports sciences》2012,30(4):395-402

The aim of this case study was to determine whether a sailor's deliberate choice of a conservative strategy to manage sleep deprivation would allow him to cross the Pacific Ocean and to minimize his state of anxiety and perceived fatigue. The participant, who had more than 10 years' sailing experience in severe conditions, was tested on a small catamaran without any living quarters during a solo Pacific Ocean crossing. Estimations of sleep hours, state anxiety, and perceived fatigue were self-reported by the sailor on a daily basis using a specific questionnaire. The most important finding is that the sailor's deliberate sleep strategy, 5.4 h sleep per day (24% less than on-shore), was enough to keep his anxiety and perceived fatigue within acceptable limits and enabled him to achieve his goal, which was the first crossing of the Pacific Ocean on a catamaran of less than 6 m. In conclusion, our results suggest that the sailor observed in the present case study was able to minimize anxiety and perceived fatigue with adequate sleep to optimize his performance, security, and to achieve his goal.  相似文献   

Δ-distance: A family of dissimilarity metrics between images represented by multi-level feature vectors     

Marta Rukoz  Maude Manouvrier  Geneviève Jomier 《Information Retrieval》2006,9(6):633-655

This article presents the Δ-distance, a family of distances between images recursively decomposed into segments and represented by multi-level feature vectors. Such a structure is a quad, a quin or a nona-tree resulting from a fixed and arbitrary image partition or from an image segmentation process. It handles positional information of image features (e.g. color, texture or shape). Δ-distance is the generalized form of dissimilarity measures between multi-level feature vectors. Using different weights on tree nodes and different distances between nodes, distances between trees or visual similarity between images can be computed based on the general definition of Δ. In this article, we present three Δ-based distance families: two families of distances between tree structures, called -distance( for Tree) and -distance ( for Segment), and a family of visual distances between images, called ( for Visual). The -distance visually compares two images using their tree representation and the other two distances compare the tree structures resulting from image segmentation. Moreover, we show how existing distances between multi-level feature vectors appear to be particular cases of the Δ-distance  相似文献   

Coherence in professional education: does it foster dedication and identification?     

Kåre Heggen  Lars Inge Terum 《Teaching in Higher Education》2013,18(6):656-669

This article examines the impact of professional education on students' dedication to and identification with a profession. The premise is that professional education is not only about knowledge acquisition and reasoning but also about attitudes and aspirations. In fostering dedication and identification, students' experiences of relevance seem to be important. The concept of coherence seen as an expression of relevance is introduced and measured by four kinds of interactions: Theory–practice interaction, teacher–student interaction, peer interaction and supervisor–student interaction. Analysis indicates that coherence, particularly as theory–practice interaction, peer interaction and supervisor–student interaction, has a significant impact on dedication to and identification with a profession. Longitudinal survey data – collected from students in colleges for teaching, nursing and social work – are analysed.  相似文献

College students' views on criminal justice     

Margaret Farnworth  Dennis R. Longmire  Vincent M. West 《Journal of Criminal Justice Education》2013,24(1):39-57

We surveyed 683 college students to examine their attitudes toward the death penalty, other criminal sanctions, and the war on drugs. College seniors were consistently less likely than freshmen to hold punitive views; this suggests a “liberalizing” effect of the college experience. This liberalizing college effect on attitudes toward criminal justice was not apparent for criminal justice majors, however, particularly when criminal justice seniors' attitudes toward the death penalty were compared with those of freshmen in criminal justice. The views of criminal justice majors overall did not differ appreciably from other students' views. We found no support for the expectation that criminal justice majors with experience in criminal justice would express more conservative, more punitive views than would criminal justice majors in general.  相似文献   

Spelling,Reading Abilities and Speech Perception in Deaf Children with a Cochlear Implant     

Marie Simon  Lauren A. Fromont  Marie-Thérèse Le Normand 《Scientific Studies of Reading》2013,17(6):494-508

ABSTRACT

This study aims to compare word spelling outcomes for French-speaking deaf children with a cochlear implant (CI) with hearing children who matched for age, level of education and gender. A picture written naming task controlling for word frequency, word length, and phoneme-to-grapheme predictability was designed to analyze spelling productions. A generalized linear mixed model on the percentage of correct spelling revealed an effect of participant’s reading abilities, but no effect of hearing status. Word frequency and word length, but not phoneme-to-grapheme predictability, contributed to explaining the spelling variance. Deaf children with a CI made significantly less phonologically plausible errors and more phonologically unacceptable errors when compared to their hearing peers. Age at implantation and speech perception scores were related to deaf children’s errors. A good word spelling level can be achieved by deaf children with a CI, who nonetheless use less efficiently the phoneme-to-grapheme strategy than do hearing children.  相似文献
