ABSTRACTThis study assessed the intra-individual reliability of oxygen saturation in intercostal muscles (SmO2-m.intercostales) during an incremental maximal treadmill exercise by using portable NIRS devices in a test-retest study. Fifteen marathon runners (age, 24.9 ± 2.0 years; body mass index, 21.6 ± 2.3 kg·m?2; V?O2-peak, 63.7 ± 5.9 mL·kg?1·min?1) were tested on two separate days, with a 7-day interval between the two measurements. Oxygen consumption (V?O2) was assessed using the breath-by-breath method during the V?O2-test, while SmO2 was determined using a portable commercial device, based in the near-infrared spectroscopy (NIRS) principle. The minute ventilation (VE), respiratory rate (RR), and tidal volume (Vt) were also monitored during the cardiopulmonary exercise test. For the SmO2-m.intercostales, the intraclass correlation coefficient (ICC) at rest, first (VT1) and second ventilatory (VT2) thresholds, and maximal stages were 0.90, 0.84, 0.92, and 0.93, respectively; the confidence intervals ranged from ?10.8% – +9.5% to ?15.3% – +12.5%. The reliability was good at low intensity (rest and VT1) and excellent at high intensity (VT2 and max). The Spearman correlation test revealed (p ≤ 0.001) an inverse association of SmO2-m.intercostales with V?O2 (ρ = ?0.64), VE (ρ = ?0.73), RR (ρ = ?0.70), and Vt (ρ = ?0.63). The relationship with the ventilatory variables showed that increased breathing effort during exercise could be registered adequately using a NIRS portable device. 相似文献

The contribution of universities to society is due to the effects generated both in the supply and in the demand side, the latter being associated with the injection of demand as a result of the activities these institutions carry out. This paper focuses on the impact of the demand side by designing a methodology based on Monte Carlo simulations so as to introduce stochastic elements in calculating the economic impact of universities. We apply this methodology to the case of Valencian public universities, introducing stochastic elements in all the elements which imply assumptions with uncertainty. The results highlight the importance of considering uncertainty by generating multipliers which can vary around the average value by 18 % in the case of output and employment, and 10 % in the case of income. 相似文献

ResumenSe aborda en este trabajo la dominancia o lateralización hemisférica cerebral, en cuanto posible factor etiológico de interés para la neuropsicología de la dislexia evolutiva. Se precisan las relaciones con la lateralidad manual y se revisan, a la luz de los conocimientos actuales, los conceptos legados por Broca y Orton. En este sentido, también se revisa la teoría de la dominancia desde el principio (Kinsbourne) en cuanto contrapuesta a la teoría de la progresiva lateralización hemisférica en la ontogenia (Lenneberg). Los principales modelos de dislexia basados en la organización cerebral se agrupan según hagan referencia a la integración interhemisférica, a la especialización hemisférica o a la integración intersensorial. Como aplicación a la educación, se proponen algunas consideraciones generales derivadas del enfoque neuropsicológico y se revisa críticamente el carácter generalizador de una educación basada en la hemisfericidad. 相似文献

Executive functions (EF) are a set of processes that allow individuals to plan, monitor and organize tasks and thus play a key role in the development of reading and maths skills. Environmental factors such as socioeconomic level (SEL) influence reading and maths skills as well as EFs. The aim of this study is to explore the extent to which executive functions play a mediating role between SEL and reading and maths performance. To this end, we assessed 286 Chilean primary education students: 86 with a high SEL and 200 with a low level. The results show that the high-SEL group obtained consistently higher scores than their peers with low SEL levels in both reading and maths tasks as well as in EF measurements. This suggests that SEL could influence the development of these variables. The results also showed that EFs partially mediate the relation between SEL and reading and maths skills in primary school students through the specific function of inhibition. The results are discussed in light of the effect of SEL on the development of EFs and school learning. 相似文献

Cognates are words that are the same or nearly the same orthographically and semantically in English and Spanish. The majority of the more than 20,000 cognates are academic vocabulary words comprised of Latin and Greek roots and affixes. Several thousand cognates can be found in the picture books that have earned the Américas Book Award, which was established to honor quality multicultural books that portray Latino cultures in a positive light. The authors present lessons for teaching primary school Latino ELLs about cognates through the Américas Award picture books, as they educate their students about their rich Latino cultures. 相似文献

In recent years, university education has changed considerably, adapting to the prevailing circumstances and proving itself an essential resource in the optimisation of the professional, social and cultural domains. In short, the changes experienced by university education have led to the achievement of quite significant results. However, at the same time we have also witnessed the emergence of certain misgivings about the nature of this education, above all in relation to the personal, ethical and civic development of today’s student populace. This paper focuses on these concerns, and in so doing, it revisits a past in which essential philosophical ideas were being formulated about higher education, ideas that this paper argues are highly pertinent to current reality. 相似文献

In the last 30 years, different economic, political and social changes have taken place in the university sector and this has led to an extensive reform to meet the new societal challenges that these institutions are facing today. This emphasises the social dimension of universities and their important role in society as educators of future leaders and policy makers. This reveals the need to integrate social responsibility principles into the mainstream functions of universities. In view of these comments, this paper offers a review of the literature about university social responsibility during the period from 2000 to 2015. The objectives of the review are to: explore patterns in publication outlets; collect, scrutinise and critically analyse the current literature on this field; to identify gaps in the literature and make recommendations for further research in this field. To accomplish this task, data were collected from 15 specialist academic journals that focus on higher education. 相似文献

Students’ conceptions and beliefs about learning are constructs that have been proposed in two independent lines of research, phenomenographic and metacognitive, and analysed using qualitative and quantitative methodologies, respectively. The present research examines and integrates in a single study both constructs and methodologies. Data were collected through an open-ended task (Tynjäla, 1997) and an epistemological questionnaire (Schommer, 1990), administered to a sample of 1,200 secondary students. Three major statistically significant findings emerged. First, students’ conceptions of learning and epistemological beliefs changed from simplistic to more complex as they progressed through school. Second, the two constructs were linked to each other. The most advanced category on the ‘dimension of depth’ of learning conceptions corresponded to the highest scores at the complex pole of the belief system. Third, learning conceptions as well as epistemological beliefs were predictors of academic performance. The more capable students were of constructing meaning, the better their academic achievement appeared to be. Theoretical and educational implications are discussed with regard to further research, classroom instruction, and the value of combining both research methodologies in order to deepen our understanding of students’ learning experience. 相似文献
