Artistic Understanding and Motivational Characteristics          下载免费PDF全文

Pablo Lekue 《The International Journal of Art & Design Education》2015,34(1):44-59

This study aims to analyse artistic understanding in primary and secondary education and the relationship between this understanding and motivational characteristics such as goal orientation, engagement in art activities and attitude to art education at school, which determine (according to prior research) learners' academic achievement, in this case the achievement of a group of young students aged between 10 and 17. A positive relationship was hypothesised between artistic understanding and achievement goals, engagement in art activities and attitudes towards art education, respectively. The results obtained partially support this hypothesis, since a statistically significant relationship was observed between artistic understanding and achievement goals, and the significant relationships hypothesised between artistic understanding and both engagement in art activities and attitudes to art education are largely supported by the findings of this study.  相似文献   

Energy cost and kinematics of level,uphill and downhill running: fatigue-induced changes after a mountain ultramarathon     

Gianluca Vernillo  Aldo Savoldelli  Andrea Zignoli  Spyros Skafidas  Alessandro Fornasiero  Antonio La Torre 《Journal of sports sciences》2015,33(19):1998-2005

This study aimed to determine whether the fatigue induced by a mountain ultramarathon (MUM) led to changes in energy cost and kinematic during level and graded running. Pre- and post-race, 14 ultratrail runners ran on a level, uphill (5%) and downhill (5%) treadmill at 10 km · h^?1. Kinematic data were acquired using a photocell system. Post-race, the downhill energy cost increased by 13.1% (P < 0.001). No change was noted in level and uphill running. Duty factor and stride frequency were increased, whereas swing time, cycle time and stride length were decreased in all conditions (P < 0.05). Contact time was increased and the rate of force generation was decreased only in the uphill and downhill conditions (P < 0.05). Positive correlations were observed between performance time and the pre- to post-changes in the energy cost of level (r = 0.52, P = 0.04) and uphill running (r = 0.50, P = 0.04). MUM-induced fatigue resulted in physiological and spatiotemporal changes, though the response to fatigue varied considerably between running conditions. These changes resulted in a significant increment only in the downhill energy cost. Incorporating downhill locomotion in the training programmes of ultratrailers may help to improve performance-related physiological and biomechanical parameters.  相似文献   

实际塑性铰链位置对延性框架行为的影响     

M assimiliano FRALDI Antonio GESUALDO Federico GUARRACINO 《浙江大学学报(A卷英文版)》2014,15(7):482-495

研究目的：研究方法：通过有限元分析和极限分析,研究了在纵向和横向载荷下钢框架的最大负荷和坍塌模式,并考虑了塑性铰链住轴向力和弯曲力矩的作用下住实际旋转时的运动学。在垂直和水平方向载荷共存的情况下,基于轴向力和弯曲力矩的交互作用,研究延性框架的极限载荷和坍塌模式对产生于塑性铰链的真实运动学的敏感性。通过两个基本的案例和通过成功地评估非线性有限元分析和直接实施的极限分析步骤,并利用MATHEMATICA,揭示了其敏感性。 在标准规程的框架下,即使在最简单的案例中,极限分析的主要结果也会考虑在坍塌时的运动学,这与设计和加固的目的都是相关的。如果没有对所有的结构元件的轴向力和弯曲力矩的交互作用进行合理的计算,塑性铰链的定位计算可能得出不正确的坍塌机理和误导性的安全系数。就具体方面而言,本文清楚地表明,在设计新的结构或者为现有结构进行加固时,即使是使用看起来已经非常完备的经典步骤,也必须非常小心。本文的模型可以为处理规程设计的执业工程师和标准化委员会提供参考。  相似文献   

Towards a heuristic frame for transferring e-government technology     

Gabriel Marcuzzo do Canto Cavalheiro  Luiz Antonio Joia 《Government Information Quarterly》2014

This article addresses challenges in accomplishing technology transfer process involving the adaptation and implementation of e-government applications from a donor country to a recipient country. Here it is claimed that prior e-government research has overlooked existing technology transfer literature from the field of knowledge management. This work is aimed at addressing the underlying issues associated with the transfer of e-government technology, given different characteristics of donor and recipient organizations in terms of the socio-economic context and the dynamics of the technological infrastructure. Based on a review, interpretation, and synthesis of a broad range of both technology transfer, e-government and knowledge management literature, we extend the Information Technology Transfer Life-Cycle Model, as this well-known model was derived entirely based on empirical evidence. To this end, we propose a heuristic frame for e-government technology transfer. Finally, five propositions accrued from both the literature review and the proposed heuristic frame are set forth to be further tested, in order to better understand the process dynamics of e-government technology transfer between countries.  相似文献

From the Periphery to Center Stage: The Effects and Exploitation of the Other in Titus Andronicus and Assassin’s Creed III     

Marco Antonio Rodriguez 《The Communication Review》2014,17(3):245-255

Aaron the Moor from Titus Andronicus and Ratonhnhaké:ton from Assassin’s Creed III are each aiding in a war against an international superpower, and both characters are plotting ways to advance and improve their respective culture. Aaron is seen as the villain and the antagonist, whereas Ratonhnhaké:ton is seen as an individual who fights for freedom. However, once both characters’ usefulness is exhausted, they are easily characterized as the Other and lose whatever benefits they may have earned. They are tossed aside by the factions they are trying to help. Even though Assassin’s Creed III is a video game, the same issues of colonialism and imperialism can be investigated in this 21st-century genre as in Shakespeare’s play.  相似文献

A variational method for the numerical simulation of a boundary controllability problem for the linear and semilinear 1D wave equations     

Ernesto Aranda  Pablo Pedregal 《Journal of The Franklin Institute》2014

We pursue the numerical implementation of a boundary controllability problem for the 1D wave equation based on a recent variational approach to deal with such situations that consists in analyzing an error functional defined for feasible functions complying with appropriate initial, boundary, and final constraints. The nature of such scheme, as a minimization process for a certain error functional, leads to a natural numerical implementation by using typical descent algorithms. Our aim here is to explore the basic ingredients to set up such practical numerical approximations which allow us to address linear and semilinear equations with the same numerical scheme.  相似文献   

Knowledge transfer activities in social sciences and humanities: Explaining the interactions of research groups with non-academic agents     

Julia Olmos-Peñuela  Elena Castro-Martínez  Pablo D’Este 《Research Policy》2014

The aim of this research is to achieve a better understanding of the processes underlying knowledge transfer (KT) in social sciences and humanities (SSH). The paper addresses: first, the extent of SSH research groups’ engagement in KT and the formal KT activities used to interact with non-academic communities; and second, how the characteristics of research groups may influence engagement in various types of KT. The empirical analysis is at research group level using data derived from a questionnaire of SSH research groups belonging to the Spanish Council for Scientific Research (CSIC). We find that KT activities are based on relational rather than commercial activities. The most frequent relational activities in which SSH research groups engage are consultancy and contract research. We find also that the characteristics of research groups (e.g. size and multidisciplinarity) and individuals (e.g. academic status and star scientist) are associated with involvement in KT activities and that a deliberate focus on the societal impacts and relevance of the research conducted is strongly related to active engagement of research groups in all the modes of KT considered in this study. From a managerial perspective, our findings suggest that measures promoting a focus on the societal impact of research could enhance research groups’ engagement in KT activities.  相似文献
