Validation of Using Smartphone Built-In Accelerometers to Estimate the Active Energy Expenditures of Full-Time Manual Wheelchair Users with Spinal Co…
2021
[EN] This study aimed to investigate the validity of using built-in smartphone accelerometers to estimate the active energy expenditures of full-time manual wheelchair users with spinal cord injury (SCI). Twenty participants with complete SCI completed 10 5-min daily activities that involved the upper limbs, during which their oxygen consumption and upper limb activity were registered using a portable gas analyzer and a smartphone (placed on the non-dominant arm), respectively. Time series of 1-min averaged oxygen consumption and 55 accelerometer variables (13 variables for each of the four axes and three additional variables for the correlations between axes) were used to estimate three mu…
Nordic walking influence on biomechanical parameters: a systematic review
2020
INTRODUCTION Nordic walking (NW) as a form of physical activity has been shown to have benefits in various domains, but little is known about the effect of NW on more specific biomechanical parameters. The purpose is to determine the impact of NW on the following parameters: walking speed/distance, muscle activation, spatiotemporal parameters, kinematics and ground reaction force. EVIDENCE ACQUISITION A literature search was carried out in different databases from October 2008 to October 2018. This review was conducted and reported in accordance with the PRISMA statement. Finally, 42 studies with a median PEDro Score of 5.5/10 were included. EVIDENCE SYNTHESIS The included studies reported …
Cadmium, Copper and Tributyltin effects on fertilization of Paracentrotus lividus (Echinodermata)
2009
Marine environments are continuously being threatened by a large number of xenobi- otics from anthropogenic sources. The effect of chemical pollution on living organisms are numerous and may impair reproductive success of adults species of marine invertebrate and vertebrate through effects on gamete quality. Echinoderms are characterized by external fertilizzation and gametes, free of any type of protection, may be in contact with toxic substances so the reproductive success depends largely on the environment conditions. The purpose of this work is to assess the effects on the in vitro fertiliza- tion of exposure of sea urchin Paracentrotus lividus gametes to xenobiotic substances as CuSO4,…
Les managers de proximité face aux compétences : une approche située
2013
Line managers and qualifications: a situated approachQualifications have seldom been analyzed as closely as possible to the operational level, a possibility of special interest to line managers and a genuine issue for research and management. Supervisors are continually in the position of making judgments about the qualifications of the persons and work teams whose activities they organize to reach the objectives set. Starting from observations conducted in several situations at the workplace, the concept of a “qualification oriented toward the situation” is drawn up around three dimensions : situation, qualification and performance. Its usefulness is empirically illustrated in the case of …
Daily Fluctuations in Motivation
2019
Abstract. Intrinsic and extrinsic motivation are related to learning success and academic achievement of university students. Process models of self-regulated learning (SRL) suggest that daily academic motivation is affected by study satisfaction on the previous day. In this study, we conducted a secondary analysis of the data by Liborius et al. (2019) , in which the study behavior of a total of 105 students was surveyed daily over 154 days (including both the lecture period and non-lecture period). We tested a mediation model, assuming that SRL components (planning, self-efficacy, time investment, concentration, effort, and procrastination) increase intrinsic motivation and decrease extri…
Innovative culture in district innovation systems of European ceramics SMEs
2017
We need to understand the dynamics of current local production systems in the form of industrial districts and, particularly, how culture and innovation are interlinked. In this paper, we argue that the district innovation system approach, which covers the innovation systems and industrial district literatures, provides a set of ideas useful for understanding the role of culture in innovation in industrial districts. We study the role of innovation culture in two of the most important European ceramics industrial districts in Italy and Spain. Specifically, we analyse how, within a given district system, the innovation culture, networks and social structure, and their inter-relations, influe…
Physical activity in and out-of-school and academic performance in Spain
2020
Background: Academic performance in school stems from an interaction of factors associated with students, families and schools. Among these factors, physical activity could play a very relevant role. Objective: The goal of this study was to determine whether students’ physical activities in and outside school were related to their academic performance. Design, setting and method: We used the Programme for International Student Assessment (PISA) 2015 database for Spain using ordinary least squares (OLS) regression models to answer our research questions. Results: Results suggest a positive association between the number of days per week doing moderate physical activities and academic perform…
Assessment of learning strategies with the ACRA and the Brief-ACRA scales: Competitive models, measurement invariance, and prediction of academic ach…
2021
Abstract Learning strategies have been widely studied, and they have been related to academic achievement in several studies. Among the measurement instruments developed, the 44-item version of the Learning Strategies Scale (ACRA) is, by far, one of the most widely used questionnaires in the Spanish speaking context. This instrument has been recently shortened to a 17-item version. Neither the 44-item nor the 17-item version have been tested in the Dominican Republic. The aim of this study is to study the psychometric properties of the 44-item and 17-item versions of the ACRA. Participants were 1712 Dominican secondary school students. Both structures of the ACRA were tested via CFA; alpha …
Learning How to Tell, Learning How to Ask: Reciprocity and Storytelling as a Community Process
2020
AbstractIn this article, we discuss the discursive processes that surround storytelling of traumatic experiences in the case of minor asylum seekers involved in the recent migration flow to Italian ports. We argue that in order to understand not only how traumatic experiences are told but also how they are overcome, it is necessary to focus on the reciprocal relationships and impact of the members of the communities in which migrants are received. Such approach shifts the focus from the content of stories toward the protagonists of their tellings and from asylum seekers as ‘subjects’ to asylum seekers as members of communities to which they and others contribute. The article is based on nar…
Transforming student contributions into subject-specific expression
2021
Drawing on a corpus of pre-service teacher training classroom interactions in an English-medium instruction university in Turkey, we examine teacher follow-up turns that introduce specialized terms, showing how a teacher transforms student’s responses into pedagogically relevant points using academic language. We argue that teacher third-turns following student contributions accomplish several interrelated actions, not only introducing new terminology to these teachers-in-training, but also familiarizing them with ways of thinking specific to their discipline, i.e., these turns model “doing being a teacher.” These teacher actions are used to bridge student contributions to more scientific t…
