The protective action of remote ischaemic preconditioning (RIPC) has been demonstrated in the context of surgical interventions in cardiology. Application of RIPC to sports performance has been proposed, but its effect on the electrocardiogram (ECG) during exercise remains unknown. This exploratory study aims to measure the changes in ventricular repolarization observed during exercise following RIPC in healthy subjects. In an experimental randomized crossover study, 17 subjects underwent two bouts of constant load exercise tests at 75% and 115% of gas exchange threshold (GET). Prior to exercise, they were allocated to either control or RIPC intervention with four cycles of 5?min of ischaemia followed by 5?min of reperfusion. ECG was continuously recorded during the protocol. QT and RR intervals were measured every 30?s (on an average tracing of the preceding 10?s). Although the time course of RR intervals did not differ between the two interventions (p?=?.56 at 75% GET and p?=?.74 at 115% GET), a significant shortening of QT intervals (measured from Q onset to T end) was observed during exercise (mean?±?standard deviation of RIPC vs. control: ?32?±?19?ms at 75% GET (p?p?p?p?相似文献

The French orthographic code is complex, and its acquisition is laborious (Catach, 2008; Fayol & Jaffré, 2008). Three hypotheses attempt to explain orthographic knowledge acquisition (OKA). For some, exposure to the code leads to OKA through a self-learning process (Share, 2004). For others, OKA benefits from graphophonological processes (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001). Finally, some authors suggest that OKA is possible thanks to visual specific processes (Ans, Carbonnel, & Valdois, 1998). The main goal of this study was to test these hypotheses in a classroom context with comparable samples. In total, 143 2nd-grade children participated in this quasi-experimental study with a pretest, immediate posttest, and delayed posttest design. We assigned participants to one of four conditions. For three conditions, we created three teaching procedures based on each of the hypotheses: frequency of contacts with target words; explicit teaching of graphophonological properties of words; explicit teaching of visual properties of words. The fourth served as a control group. ANOVA analyses indicated that all three experimental conditions favored OKA, showing that the different teaching procedures led to spelling development. However, the visual condition was the most favorable. Three main conclusions can be drawn from this study: (a) models of OKA should account for the different paths that can lead to spelling acquisition; (b) visual properties of words and their acquisition need additional research, and (c) applied research in real classroom contexts is not only relevant for informing teaching practices but also for better understanding how learning takes place.

Using phenomenological inquiry, this study explored the lived experiences and intersecting identities of 8 African American counselor educators who are mothers. Six themes were identified: race, professional strain, work–life balance, support, internalized success, and mothering pedagogy. 相似文献

Relationships have been found between teacher efficacy and many teaching and learning variables, but few researchers have examined teaching efficacy in physical education. The instrument reported here, the Physical Education Teaching Efficacy Scale, was developed based on the teaching efficacy literature, existing scales, and National Association for Sport and Physical Education's Teacher Education Standards. Students attending 11 institutions who are majoring in regular and alternate physical education teacher education and who are at different stages of preparation (N?=?592) completed the initial survey. Exploratory, followed by confirmatory, factor analysis resulted in a 35-item, 7-factor scale. Factors were Content Knowledge, which were activities one might teach; Applying Scientific Knowledge in Teaching, which reflected academic content; Accommodating Skill Differences; Teaching Students with Special Needs; Instruction, which included management, motivation, and instruction; Using Technology; and Assessment. Results support that the Physical Education Teaching Efficacy Scale addresses many aspects of teaching physical education and meets research criteria for validity and reliability. 相似文献

This article reports on an investigation of graphophonological processes in deaf readers of French over a 1-year period. Deaf readers are known to have a phonological deficit compared to hearing peers, and conclusions from studies on this question are often conflicting. Among the different types of phonological processing, we can identify graphophonological processes based on correspondences between the oral and the written language. In this investigation, we evaluated graphophonemic and graphosyllabic processes using, in each case, two different tasks varying in their degree of cognitive constraints (CC- vs. CC+). Nineteen 11 year-old deaf students were compared to younger normal readers of the same reading level (RA, n = 17) and to normal readers of the same age (CA, n = 20). Two variables were considered in the analyses: accuracy and response latency. Results show that deaf readers do process written items at the graphophonological level and that graphophonological processes are related to reading ability. Also, results indicate main effects of task (CC- vs. CC+), time (T1 vs. T2), and group. In general, deaf participants' performances are comparable to those of RA and differ from those of CA. Results are discussed within the framework of the study of phonology in deaf readers and its relation to reading acquisition. 相似文献

The development of spelling skill is a very difficult task for students with dyslexia. Spelling in French involves the consideration of various types of knowledge, procedures and strategies. This study aims to describe the spelling strategies of 32 dyslexic students (DYS) aged from 8 to 12 years and to establish links between spelling strategies and spelling skill. Students had to spell 24 dictated words and provide comments on the strategy employed for each word. The performances of DYS were compared to 25 children of the same chronological age (CA) and of 24 children of the same reading age (RA). The results show that phonological strategies are the most commonly used by all groups of participants. If no particular strategy is related to the spelling skill of DYS, visuo-orthographic strategy generally accounts for the spelling skill results of CA and RA. 相似文献

The authors examined the occupational satisfaction of 107 counselor educator mothers and found that work‐to‐family enrichment, support from colleagues, and number of children under age 6 were significant predictors of occupational satisfaction. These results underscore the importance of policies and programs to increase occupational satisfaction of academic mothers and to support their recruitment and retention. 相似文献

在技术全会上,IAB（互联网体系结构委员会）讲述了他们在IP模型演进方面的工作。在他们的工作中,IP模型指由IP层向上层协议和应用程序暴露的服务模型（图1）。也就是说,IP模型可以看成一套被更上层依赖的行为,或者一套上层对IP的期望。从这种意义上说,它就像一个发展了很长时间的松散的约定。 相似文献
