Abstract The purpose of the present study was to investigate the socio-demographic and lifestyle determinants of physical activity practice, as well as the motivations for being or not being physically active in Spanish university students. A representative sample of students from a Spanish university (n = 2,051; 42.1% males; mean age 21.9, s = 4.8 years) participated in the present cross-sectional study. A questionnaire including questions regarding lifestyle, dietary habits, parents' characteristics, and physical activity habits was administered to the students. The socio-demographic and lifestyle determinants of physical activity practice were assessed using multivariable logistic regression. 68.4% of men and 48.4% of women reported to practise physical activity in the present sample. Those who practised physical activity consumed more fruits and were less likely to be smokers compared to non-physically active students. Also, physically inactive men spent more time in front of the computer and physically inactive women spent more time in front of the TV and were more likely to be frequent alcohol consumers. Maternal educational level and maternal physical activity habits were also important determinants of physical activity practice among men and women respectively. In conclusion, physically active students tended to engage in other healthy habits in the present population, suggesting the clustering of healthy or unhealthy lifestyle factors among specific subgroups. 相似文献

ResumenEn el presente trabajo se muestra un procedimiento para conseguir mejorar el nivel de velocidad lectora en jóvenes con discapacidad motora, en su mayoría afectados de parálisis cerebral y que presentan problemas fonoarticulatorios o de ausencia de habla. Se utilizó con éxito un programa de ordenador llamado Speed Reader II, que está diseñado para desarrollar técnicas de lectura rápida. En los sujetos objeto de estudio dicho programa permitió mejorar la velocidad lectora, probablemente porque el procedimiento empleado favoreció el reconocimiento visual de palabras y la interpreta—ción y anticipación del contenido a partir del contexto. Se observa, sin embargo, la necesidad de que los sujetos dispongan una mínima habilidad lectora de partida para que el progreso con este programa sea significativo. 相似文献

The dropout rate among Spanish university students is very high compared to the European mean, creating a pressing need for the introduction of policies and programmes aimed at increasing rates of persistence. In this article, we study this problem by combining students’ perceived learning outcomes with their dropout intentions, and we propose a research model that considers subjective factors that might impact this decision. The model is estimated for two degree courses: Business Administration and Nursing. The estimation method uses structural equations based on the partial least squares algorithm. This allows the construction of indices for the variables of interest, enabling us to make comparisons between courses and over time. To reduce dropout intentions, efforts need to be focused on obtaining better cognitive outcomes, as well as on achieving a higher level of student satisfaction with their university experience. 相似文献

The aim of this article was to analyse the initiative FC Barcelona Peace Tour 2013, in Israel and Palestine. This research is based on lengthy interviews with people associated with the initiative and the use of primary sources, both institutional and journalistic. Secondary sources have also been used, such as journalistic accounts of the initiative. The article thus examines the nature of FC Barcelona Peace Tour 2013, which it defines as an exercise in sports diplomacy, inspired by civil society and articulated through the club. The article concludes that FC Barcelona has been able to act as a mediator between two opposed communities due to the universal values linked to its brand and its nature as a ‘civil religion’. This notwithstanding, the political problems that arose during the planning of the initiative highlight the geopolitical complexity of the Middle East and, by extension, the limits of sports diplomacy. 相似文献

The aim of this article is to elucidate how a new system of school and teacher assessment in Catalonia is transforming the conceptions, practices and identity of head teachers, especially younger ones. It begins by considering the impact of global neoliberal policies on educational practices, highlighting their Foucauldian productive nature. It then examines the educational context of Catalonia during the last 30 years, emphasising the changing role of head teachers and the impact of neoliberal governance. This is followed by an account and analysis of in-depth interviews with four head teachers, focusing especially on how the head teacher’s objectives, practices and identities are being transformed, or produced, as a result of the new neoliberal ‘assessment regime’. It ends with a discussion on the importance of refusal and resistance to this process and the need to reconsider basic educational and social questions. 相似文献

Helicobacter pylori are ubiquitous Gram-negative bacteria with a high estimated level of infection in the world populations, but a majority of the infected persons are asymptomatic. This pathogen has been classified by the World Health Organization as a class I carcinogen and recognized as the causal agent of most peptic ulcers and chronic gastritis that might lead to stomach cancer. Although not all the transmission pathways of these bacteria into humans have been properly identified, enough data have sugg... 相似文献

The anonymization of query logs is an important process that needs to be performed prior to the publication of such sensitive data. This ensures the anonymity of the users in the logs, a problem that has been already found in released logs from well known companies. This paper presents the anonymization of query logs using microaggregation. Our proposal ensures the k-anonymity of the users in the query log, while preserving its utility. We provide the evaluation of our proposal in real query logs, showing the privacy and utility achieved, as well as providing estimations for the use of such data in data mining processes based on clustering. 相似文献

AbstractIn this paper we present the results of a naturalistic study carried out with higher education students which describes their learning environments when working on academic tasks in groups and individually. In this study we want to analyse how they organize their learning activities and knowledge processes (reading, reflecting and sharing) and how these learning processes are integrated into their Personal Learning Environments (PLE). In order to achieve that, students had to reflect about the basic ‘components’ that make up their learning process: reading (using not only by text but also multimedia), doing/reflecting (creating cognitive artefacts) and sharing (discussing, showing, and offering and receiving feedback from and to a community of reference). Students formed relationships between those components and any technological tools they used and created mind maps to represent their PLEs. The main objective is to try to understand how PLEs are organized and how they are perceived by learners, not from a technological perspective but from a learning perspective. The main results confirm the strong nature of PLEs as a pedagogical approach with a strong technological base. In addition, those results suggest a close relationship between students’ beliefs and expectations regarding academic tasks as well as the importance they give to each component in their learning process. 相似文献
