Thermoneutral immersion exercise accelerates heart rate recovery: A potential novel training modality     

Mauricio Garzon  Olivier Dupuy  Laurent Bosquet  Anil Nigam  Alain Steve Comtois  Martin Juneau 《European Journal of Sport Science》2017,17(3):310-316

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

Conceptual change through vicarious learning in an authentic physics setting   总被引：1，自引：0，他引：1  

Derek A. Muller  Manjula D. Sharma  John Eklund  Peter Reimann 《Instructional Science》2007,35(6):519-533

Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.  相似文献

Evaluating innovative processes in french firms: Methodological proposition for firm innovation capacity evaluation     

Vincent Boly  Laure Morel  N’Doli Guillaume Assielou  Mauricio Camargo 《Research Policy》2014

Measuring innovation processes is a major concern for academics and firm managers. This study proposes an innovation capacity (IC) measure framework based on a set of 15 innovation management practices. Every practice is subdivided into multiple criteria which are directly observable phenomena or facts. The statistical method of value test and a multi-criteria approach are adopted to propose a typology of four groups of innovative firms (proactive, preactive, reactive, passive). The features observed on these groups of firms allow the determination of the firms’ innovation capacity and are useful for providing recommendations and practical actions for them, with a view to reinforcing it. Data from a sample group of 39 small and medium sized enterprises (SMEs) in the manufacturing industry in Lorraine, France were collected via a field survey and were fed into the model to determine the innovation capacity of the companies.  相似文献   

A Grounded Practical Theory Reconstruction of the Communication Practice of Instructor-facilitated Collegiate Classroom Discussion     

Heidi L. Muller 《Journal of Applied Communication Research》2014,42(3):325-342

Instructor-facilitated collegiate classroom discussion (IFCCD) is a highly valued yet undertheorized instructional practice. Research examining the structure of classroom interaction, scholarship advocating rationales for discussion-based pedagogy, and an investigation of a related interactive classroom communication practice provide an informative backdrop for this study. The data in the study were collected using action-implicative discourse analytic techniques throughout a semester in three classrooms at the same university. Reconstructing the three levels of the practice through grounded practical theory—the problem/dilemma level, the normative situated ideals level, and the talk/discourse techniques level—provides some insight into why in two of these cases of IFCCD, engaged and participatory discussion was accomplished. The shared dilemma of the practice is reconstructed as the problem of engagement in which both individual engagement with curricular content and shared engagement in co-creation of the discussion are valued. The dilemmatic nature of the practice is explored specifically in terms of traditional and nontraditional teacher talk and associated participation structures. Significant similarities and differences across the three cases are found and examined in the reconstructions of instructor situated ideals and third-turn facilitation techniques. Initial conclusions are incorporated in the discussion of discourse-based applications for practitioners interested in facilitating discussion in college classrooms.  相似文献   

Testing the double-deficit hypothesis in an adult sample     

Miller CJ  Miller SR  Bloom JS  Jones L  Lindstrom W  Craggs J  Garcia-Barrera M  Semrud-Clikeman M  Gilger JW  Hynd GW 《Annals of dyslexia》2006,56(1):83-102

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants were parents of children referred for evaluation of reading difficulties. Approximately half of all participants reported difficulty learning to read in childhood and a small subset demonstrated ongoing weaknesses in reading. Structural equation modeling results suggest that the double-deficit hypothesis is an accurate model for understanding adult reading achievement. Better reading achievement was associated with better phonological awareness and faster rapid automatized naming in adults. Posthoc analyses indicated that individuals with double deficits had significantly lower reading achievement than individuals with single deficits or no deficits.  相似文献   

The work of the audience: visual matrix methodology in museums     

Lynn Froggett  Lizzie Muller  Jill Bennett 《Cultural Trends》2019,28(2-3):162-176

ABSTRACT

Visual matrix methodology has been designed for researching cultural imaginaries. It is an image-led, group-based method that creates a “third space” research setting to observe audience groups re-enacting lived experience of an event or process that takes place in the third space of a cultural setting. In this article, the method is described through its use in relation to an art-science exhibition, Human+ Future of the species, where three audience groups with investments in technology worked with exhibition material to achieve a complex ambivalent state of mind regarding technological futures. The visual matrix has been designed to capture the affective and aesthetic quality of audience engagement in third space by showing what audiences do with what is presented to them. We argue that such methodologies are useful for museums as they grapple with their role as sites where citizens not only engage in dialogue with one another but actively re-work their imaginaries of the future.  相似文献   

Active Learning session based on Didactical Engineering framework for conceptual change in students’ equilibrium and stability understanding     

Michael Canu  Mauricio Duque  Cécile de Hosson 《European Journal of Engineering Education》2017,42(1):32-44

ABSTRACT

Engineering students on control courses lack a deep understanding of equilibrium and stability that are crucial concepts in this discipline. Several studies have shown that students find it difficult to understand simple familiar or academic static equilibrium cases as well as dynamic ones from mechanics even if they know the discipline’s criteria and formulae. Our aim is to study the impact of a specific and innovative classroom session, containing well-chosen situations that address students’ misconceptions. We propose an example of Active Learning experiment based both on the Didactical Engineering methodology and the Conceptual Fields Theory that aims at promoting a conceptual change in students. The chosen methodology allows, at the same time, a proper design of the student learning activities, an accurate monitoring of the students’ rational use during the tasks and provides an internal tool for the evaluation of the session’s efficiency. Although the expected starting conceptual change was detected, it would require another activity in order to be reinforced.  相似文献
