This study compared heart rate recovery (HRR) after incremental maximal exercise performed at the same external power output (P_ext) on dry land ergocycle (DE) vs. immersible ergocycle (IE). Fifteen young healthy participants (30?±?7 years, 13 men and 2 women) performed incremental maximal exercise tests on DE and on IE. The initial P_ext on DE was 25?W and was increased by 25?W/min at a pedalling cadence between 60 and 80?rpm, while during IE immersion at chest level in thermoneutral water (30°C), the initial P_ext deployment was at a cadence of 40?rpm which was increased by 10?rpm until 70?rpm and thereafter by 5?rpm until exhaustion. Gas exchange and heart rate (HR) were measured continuously during exercise and recovery for 5?min. Maximal HR (DE: 176?±?15 vs. IE 169?±?12?bpm) reached by the subjects in the two conditions did not differ (P?>?.05). Parasympathetic reactivation parameters (ΔHR from 10 to 300?s) were compared during the DE and IE HR recovery recordings. During the IE recovery, parasympathetic reactivation in the early phase was more predominant (HRR at Δ10–Δ60?s, P?<?.05), but similar in the late phase (HRR at Δ120–Δ300?s, P?>?.05) when compared to the DE condition. In conclusion, incremental maximal IE exercise at chest level immersion in thermoneutral water accelerates the early phase parasympathetic reactivation compared to DE in healthy young participants.  相似文献   

Usage Comparison between an English-Language and a French-Language E-Monograph Collection in a Bilingual Canadian University     

Alain R. Lamothe 《International Information and Library Review》2020,52(2):139-160

Abstract

This article reports the results of a quantitative and systematic analysis comparing usage rates between English-language and French-language e-monograph titles at Laurentian University, Canada. Full-text viewings were collected as usage metrics. English-language e-monographs exhibited medium strength linear relationships between collection size and usage. On the other hand, French-language e-monographs exhibited weak linear relationships between collection size and usage. The French-language e-monograph collection experienced a higher rate of full-text use, relative to size. The cost-per-viewing ratio for the English-language e-monograph collection was higher than those that calculated for the French-language collection.  相似文献

The contribution of PISA to the convergence of education policies in Europe          下载免费PDF全文

Alain Michel 《European Journal of Education》2017,52(2):206-216

The international comparative studies on students’ outcomes have initiated analyses that have had a growing influence on national and sub‐national education policies in industrialised and developing countries. It is particularly the case of the OECD's Programme for International Student Assessment (PISA) which started in 2000 and has organised surveys every 3 years, so that the 2015 survey was the 6^th. Its influence has been particularly important for several reasons: 1) it assesses the basic competences in reading literacy, maths and science of 15 year‐olds students, i.e. around the end of compulsory education in many countries; 2) the assessment is based on a reliable methodology and the tests are completed by qualitative surveys and studies; 3) and the results lead to recommendations and are amplified by the media in most countries. However, it is not easy to evaluate the real impact of PISA because of the existence of other international studies such as IEA's TIMSS and, particularly in Europe, the influence of the recommendations and benchmarks of the EU that has been growing steadily in the last 25 years. Our analysis of the impact of PISA and EU policy focuses on the evolution of the education policy in France, but also studies its evolution in a few other European countries. Finally, we underline the limits of the influence of PISA and international standards in education towards a convergence of education systems because of the importance of their specific historic and cultural contexts.  相似文献   

Public and private schooling in France: an investigation into family choice     

Gabriel Langouet  Alain Leger 《教育政策杂志》2013,28(1):41-49

Since the end of the 1970s, more than a third of all French pupils have attended private schools either continuously or temporarily. The private sector appeared as a second chance, but one that was not seized in equal proportions by all social classes and was thus a source of new inequalities. Moreover, it appeared that although pupil recruitment in the public sector was more democratic, the private sector had more success in equalizing results and scholastic careers. Today school switching continues to increase: more than 40% of pupils attend or have attended the private sector at one point in time and almost one family in two makes use of it for at least one child. In this respect, we have observed important similarities in the school careers of parents and children: some families remain loyal to one of the two sectors while others switch between sectors. Ideologically-based choices seem to be on the decline: the main reason families use the private sector is to improve their childrens' education. There remain, however, important regional differences in provision and use of the private sector.  相似文献   

How to be Real and Conventional: A Discussion of the Quality Criteria of Official Statistics     

Alain Desrosières 《Minerva》2009,47(3):307-322

Are the categories used to study the social world and acting on it “real” or “conventional”? An empirical answer to that question is given by an analysis of the debates about the “quality” of statistics produced by the European National Institues of statistics in the 1990s. Six criteria of quality were then specified: relevance, accuracy, timeliness, accessibility, comparability and coherence. How do statisticians and users of statistics deal with the tension produced by their objects being both “real” (they exist before their measurement) and “conventionally constructed” (they are in a way, created by these conventions)? In particular, the technical and sociological distinction between the criteria of relevance and accuracy implies a realistic interpretation, desired by users, but that is nonetheless problematic.  相似文献   

Aesthetic experience and creativity in arts education: Ehrenzweig and the primal syncretistic perception of the child     

Alain Savoie 《Cambridge Journal of Education》2017,47(1):53-66

The pertinence and worth of arts in Quebec primary schools vary considerably from one institution and school administration to another. In this paper it is argued that well-integrated arts education would bring a large array of pedagogical benefits to students, not the least of which is the preservation and the development of aesthetic perception and creativity. Actually, teachers can rely on the syncretistic and amodal perception of the young child, a learning mode that is analogous to the aesthetic experience and fostered by art practices. The paper draws notably on Ehrenzweig and Winnicott to advocate that the school, through arts education, should preserve and make use of this precious perceptive faculty, and temper the educational bias that largely favours the logical or analytical mode of the child. It advocates for an essential developmental balance between the child’s intuitive and analytical faculties, a healthy equilibrium that arts education has the potential to instil. Children and society both have much to gain from the school’s fostering of arts education and aesthetic perception: children from their balanced development and society from future creative citizens’ contributions.  相似文献   

Phonological awareness in kindergarten: a field study in Luxembourgish schools     

Sylvie Bodé  Alain Content 《European Journal of Psychology of Education - EJPE》2011,26(1):109-128

The purpose of the present study was to assess the effectiveness of a phonological awareness training program in the specific context of the Luxembourgish educational system. The intervention was run by the kindergarten teachers in their classes with minimal external supervision. Forty-one classes of the area around Luxembourg City participated in the study. One hundred and fifty children from 20 kindergarten classes were part of the training group and 157 children from 21 classes formed the control group. At the end of kindergarten, clear training effects were observed for all phonological awareness tasks, except for the highly demanding phoneme deletion task. After 6 months of reading and writing instruction in first grade, no training effects were found in a pseudoword spelling task for the entire training group. Only at-risk children, which had the lowest performance on preschool phonological awareness measures, showed significant training effects. We conclude that early phonological awareness training may be profitably incorporated in kindergarten classroom activities, particularly for at-risk pupils, even when the language characteristics and teaching methods already concur in facilitating the understanding of the alphabetic principle.  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
