Examining pre-service teachers’ acceptance of technology-rich learning environments: A UAE case study     

Scott Parkman  David Litz  Nicolas Gromik 《Education and Information Technologies》2018,23(3):1253-1275

This study addressed the extent to which pre-service teachers at a teachers’ college in the United Arab Emirates (UAE) accepted and intended to utilize technology-rich learning environments in their future teaching practice. The effect of other significant factors on their overall acceptance, such as computer self-efficacy (CSE) and Perceived User Resources, was investigated. A final aim was to confirm the applicability of the instruments employed in this study within the unique sociocultural context of the UAE. Questionnaires utilizing a modified version of the technology acceptance model (TAM) were used to collect data. Respondents indicated strong acceptance of technology-rich learning environments. In the model, Perceived Usefulness and CSE were the two strongest predictors of Behavioral Intention. The results also supported the validity of TAM-based research within the Emirati sociocultural environment.  相似文献   

Spontaneous change from seated to standing cycling position with increasing power is associated with a minimization of cost functions     

Antony Costes  Nicolas A Turpin  David Villeger  Pierre Moretto  Bruno Watier 《Journal of sports sciences》2018,36(8):907-913

Spontaneous changes of movement patterns may allow to elucidate which criteria influence movement pattern preferences. However, the factors explaining the sit-stand transition in cycling are unclear. This study investigated if biomechanical and/or muscle activation cost functions could predict the power at which the spontaneous sit-stand transition occurs. Twenty-five participants performed an incremental test leading to the sit-to-stand transition, and subsequent randomized pedaling trials at 20 to 120% of the transition power in seated and standing position. A Moment Cost Function based on lower limbs net joint moments and two Electromyographic Cost Functions based on EMG data were defined. All cost functions increased with increasing crank power (p < 0.001) but at different rates in the seated and standing positions. They had lower values in the seated position below the transition power and lower values in the standing position above the transition power (p < 0.05). These results suggest that spontaneous change of position observed in cycling with increasing crank power represents an optimal choice to minimize muscular efforts. These results support the use of simple cost functions to define optimal settings in cycling and to assess the cost of cycling during short-term efforts.  相似文献

Fine Motor Control Underlies the Association Between Response Inhibition and Drawing Skill in Early Development     

Andrew Simpson  Reshaa Al Ruwaili  Richard Jolley  Hayley Leonard  Nicolas Geeraert  Kevin J. Riggs 《Child development》2019,90(3):911-923

Previous research shows that the development of response inhibition and drawing skill are linked. The current research investigated whether this association reflects a more fundamental link between response inhibition and motor control. In Experiment 1, 3- and 4-year-olds (n = 100) were tested on measures of inhibition, fine motor control, and drawing skill. Data revealed an association between inhibition and fine motor control, which was responsible for most of the association observed with drawing skill. Experiment 2 (n = 100) provided evidence that, unlike fine motor control, gross motor control and inhibition were not associated (after controlling for IQ). Alternative explanations for the link between inhibition and fine motor control are outlined, including a consideration of how these cognitive processes may interact during development.  相似文献   

The promise and peril of the state in neoliberal times: implications for the critical environmental education movement in Brazil     

Nicolas Stahelin  Inny Accioly  Celso Sánchez 《Environmental Education Research》2015,21(3):433-446

Neoliberal ideology has made an impact on environmental education (EE) policies and practices in Brazil. The EE in Family Agriculture Program, of national scope and administered by the Ministry of the Environment, seeks to promote sustainable development in rural areas, specifically through strategies focused on adult education and non-formal education aimed at small producers (family agriculture). This program reveals profound ideological contradictions between the critical and transformative rhetoric of public policy and the actual program structures and practices administered by the state in a dependent economy, which primarily serve to reinforce a capitalist mode of production marked by high environmental impact and deeply stratified class relations. In the neoliberal era, states intending to protect the environment through critical EE strategies suffer serious limitations due to their role as stewards of a globalized economy based on the supply of raw materials, high-impact land-use, and a cheap labor force.  相似文献   

Does research organization influence academic production?: Laboratory level evidence from a large European university     

Nicolas Carayol  Mireille Matt 《Research Policy》2004,33(8):1081-1102

The paper analyses scientific research production at the laboratory level. The evidence on which the study is based describes precisely the research activity over the period 1993-2000 of more than eighty labs belonging to Louis Pasteur University, a large and well-ranked European research university. The research organization of the labs is analysed by focusing on the characteristics of the research personnel in relation with the scores in two outcomes that are publications and patents. The paper proposes a five-classes typology of laboratories that highlights different styles of research organization and productivity at the laboratory level. It also studies the determinants of the publication performances of labs. We show how appropriate combinations of inputs in academic labs may be strongly associated to high publication performances. We find that combining full-time researchers and university professors in labs tend to preserve incentives. Highly publishing labs also patent. The size of the labs, the individual promotions, and the role of non-permanent researchers and of non-researchers are also underlined.  相似文献

Aging and tennis playing in a coincidence-timing task with an accelerating object: the role of visuomotor delay     

Lobjois R  Benguigui N  Bertsch J 《Research quarterly for exercise and sport》2005,76(4):398-406

The purpose of the present study was to determine whether playing a specific ball sport, such as tennis, could maintain the coincidence-timing (CT) performance of older adults at a similar level to that of younger ones. To address this question, tennis players and nonplayers of three different age ranges (ages 20-30, 60-70, and 70-80 years) performed a simple CT task consisting of timing their response (pressing a button) to coincide with the arrival of a stimulus at a target. The stimulus moved at either an accelerating, constant, or decelerating velocity. As expected, all participants were affected by the velocity manipulation, which led to late and early responses to accelerating and decelerating stimuli, respectively. Whereas this response bias was increasingly pronounced with advancing age in nonplayers, no difference was found among player groups of different ages. Finally, we showed that the length of the visuomotor delay could explain the effect of nonconstant velocities.  相似文献
