The rating of perceived exertion predicts intermittent vertical jump demand and performance     

Pereira G  Correia R  Ugrinowitsch C  Nakamura F  Rodacki A  Fowler N  Kokubun E 《Journal of sports sciences》2011,29(9):927-932

The aims of this study were (a) to assess the ability of the rating of perceived exertion (RPE) to predict performance (i.e. number of vertical jumps performed to a fixed jump height) of an intermittent vertical jump exercise, and (b) to determine the ability of RPE to describe the physiological demand of such exercise. Eight healthy men performed intermittent vertical jumps with rest periods of 4, 5, and 6 s until fatigue. Heart rate and RPE were recorded every five jumps throughout the sessions. The number of vertical jumps performed was also recorded. Random coefficient growth curve analysis identified relationships between the number of vertical jumps and both RPE and heart rate for which there were similar slopes. In addition, there were no differences between individual slopes and the mean slope for either RPE or heart rate. Moreover, RPE and number of jumps were highly correlated throughout all sessions (r = 0.97-0.99; P < 0.001), as were RPE and heart rate (r = 0.93-0.97; P < 0.001). The findings suggest that RPE can both predict the performance of intermittent vertical jump exercise and describe the physiological demands of such exercise.  相似文献

Active relatives and health-related physical fitness in European adolescents: The HELENA Study

Abstract High physical fitness in childhood and adolescence is positively associated with favourable health-related outcomes. Our aim was to examine the relationship between relatives' (father, mother, brother, sister, and best friend) physical activity engagement and encouragement on adolescents' physical fitness. Adolescents were part of the HELENA study, a multi-centre study conducted in 10 cities from nine European countries in 2006-2008. Participants were 3288 adolescents (48% boys, 52% girls) aged 12.5-17.5 years with valid data on at least one of the three fitness variables studied: muscular strength (standing long jump), speed/agility (4×10 m shuttle run), and cardiorespiratory fitness (20 m shuttle run). The adolescents reported their relatives' physical activity engagement and encouragement. Analysis of covariance showed that relatives' physical activity engagement (father, mother, brother, and best friend) was positively related to cardiorespiratory fitness (P?相似文献   

E-government and citizen's engagement with local affairs through e-websites: The case of Spanish municipalities     

Juan-Gabriel Cegarra-Navarro  José Rodrigo Córdoba Pachón  José Luis Moreno Cegarra 《International Journal of Information Management》2012

As a mixture of new technologies, processes and services oriented to the citizen, e-government has become one of the most important keywords for the public sector reform with proponents claiming that it guarantees transparency, accountability and better communication between local and national administrations and their public. Few if any studies have investigated the factors that might contribute to the establishment of trusting relationship between city councils and citizens. This paper examines the relative importance and significance of three types of information communication technologies (ICTs) towards the use of e-government and the development of civic engagement. We conduct an empirical investigation of 179 Spanish official town websites (web sites in the municipalities). The research findings suggest that implementing ICT not only involves a step towards an increase in the use of e-government services by people, but also provides numerous opportunities for their civic engagement. The main conclusion of this study is that although ICT can leverage the adoption of e-government, it cannot create alone engagement with traditional activities of the local government. What is missing from this relationship is a mediating variable (adoption of e-government by government officers), which in turn can greatly help to better understand how ICT impacts relationships between governments and their citizens.  相似文献   

Are determining factors of municipal E-government common to a worldwide municipal view? An intra-country comparison     

Isabel Gallego-Álvarez  Luis Rodríguez-Domínguez  Isabel-María García-Sánchez 《Government Information Quarterly》2010

The implementation of E-government aims at simplifying and improving the transactions between public administrations and their users or customers. The objective of this study is to analyze whether the factors behind the level of development of E-government among municipalities of a specific country are common to the improvement of digital administration in the largest municipalities from 81 countries worldwide. While previous studies provide evidence that municipalities from the same country, mainly those governed by left-wing parties, focus on differentiating themselves in the content of their Web sites, our findings emphasize that internationally, in the most important municipalities worldwide, all the political parties attempt to promote the development of a dynamic and participatory E-government.  相似文献   

Differences between web sessions according to the origin of their visits     

José Luis Ortega  Isidro Aguillo 《Journal of Informetrics》2010,4(3):331-337

The aim of this paper is to characterize the distribution of number of hits and spent time by web session. It also expects to find if there are significant differences between the length and the duration of a session with regard to the point of access–search engine, link or root. Web usage mining was used to analyse 17,174 web sessions that were identified from the webometrics.info web site. Results show that both distribution of length and duration follow an exponential decay. Significant differences between the different origins of the visits were also found, being the search engines’ users those who spent most time and did more clicks in their sessions. We conclude that a good SEO policy would be justified, because search engines are the principal intermediaries to this web site.  相似文献   

Comprender para aprender: Un programa para mejorar la comprensión y el aprendizaje de textos informativos     

Eduardo Vidal-Abarca  Ramiro Gilabert 《Cultura y Educación》2013,25(6):113-124

Aunque los objetivos curriculares actuales se plantean la enseñanza del lenguaje escrito de modo que permita utilizarlo como instrumento para el aprendizaje, el hecho es que esta enseñanza de la lectoescritura como medio se contempla como un fin en sí mismo, es decir, con materiales y contenidos literarios y no de áreas disciplinares específicas en que el niño se tendrá que mover a lo largo de toda la escolaridad. En este artículo se presenta un programa experimentado con éxito en las áreas de ciencias naturales y sociales para mejorar en los alumnos estas necesarias estrategias de comprensión y estudio.  相似文献
