There is inconclusive evidence concerning the effects of routine participation in ultra-endurance events on cardiovascular disease (CVD) risk. Arterial compliance is a reliable, non-invasive, and effective tool for evaluating CVD risk. The purpose of this research was to examine if race length influences acute changes in arterial compliance following an ultra-marathon event. A total of 46 ultra-marathon runners were recruited including 21 participants (39.8?±?8.3?years, 6 females) in the 80-km event and 25 participants (43.7?±?9.8?years, 3 female) in the 195-km event. Arterial compliance was measured via radial applanation tonometry (CR-2000, HDI) for diastolic pulse contour analysis before and following the race. Significant between-group differences were found for changes in large arterial compliance with a decrease (increase in stiffness) following the 195-km event and an increase following the 80-kilometre event (p?<?.05). Longer race lengths are associated with greater reductions in large arterial compliance following recreational ultra-marathon running. Assessment of arterial compliance might be a useful prognostic tool to assess the long-term risk of CVD among ultra-marathon runners.  相似文献

Cinema Demand in Spain: A Cointegration Analysis   总被引：4，自引：3，他引：1  

VÍctor FernÁndez Blanco  JosÉ F. BaÑos Pino 《Journal of Cultural Economics》1997,21(1):57-75

In this paper we explain the decline in cinema attendance in Spain since 1968. We use a cointegration analysis to estimate an individual demand function for cinema, with annual data and in terms of average attendance per inhabitant. We find that cinema is a luxury good and that its demand is elastic with respect to its price. We also show that television acts as a deterrent with regard to cinema attendance. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献   

Writing instruction for social justice: an investigation into the components of a teacher preparation course     

Émilie Lavoie  Martine Cavanagh 《Literacy》2023,57(2):132-148

Future teachers must notice, navigate, and address ideologies in order to counter inequities in the literacy classroom. This article presents the findings of two teacher educators who have taken up the call to critically reflect on their own underlying beliefs and discourses regarding writing instruction. Through an education design framework, they analysed important components of the course, arguing for a higher degree of visibility of the ideologies and social forces that impact writing instruction. They found that despite encouraging a fairly complex and all-encompassing view of learning to write to the future teachers in their course, the creativity discourse was present passively and the socio-political was downright absent, despite clear social justice aims in the course. They discuss how well-established discourses can serve as gateways to embed the socio-political into the course and address more granularly the question of exclusion through selected mentor texts.  相似文献

Motivational Profile and Academic Achievement Among Students Enrolled in Different Schooling Tracks     

THÉRÈSE BOUFFARD  NATHALIE COUTURE 《Educational studies》2003,29(1):19-38

From the contextual perspective, researchers argue that the relevance and weight of motivational variables of students' functioning vary depending on different dimensions related to individual, cultural or situational characteristics. The first objective of this study examined this contention by comparing self-perceptions of competence, learning goals and judgments of usefulness of school subjects as motivational determinants of high school students' commitment and achievement according to their assignment to their learning abilities. The second objective was to compare how these variables related to academic commitment and achievement according to the type of student and two school subjects. Two-hundred-and-twenty-six high school students from a same school participated sixty-one were learning disabled students, 60 were high achievers and 105 were average students. Findings suggest that the relevance of the motivational variables did not vary much across either the type of student or the school subjects. They also support Bandura's view about the primary role of self-perceptions of competence in students' academic commitment and achievement.  相似文献

Developmental Achievements of 7‐year‐old Children in Poland in the Light of International Tests and the Requirements of the Polish Language School Program     

Barbara BielÉn  Hanna Malkowska‐Zegadlo 《International Journal of Early Years Education》1998,6(2):185-197

The language competence and reading comprehension of 406 7‐year‐old children are examined in the research discussed in this article. The children were tested using comparative tests as part of an international project conducted in 14 countries and sponsored by the IEA and the High Scope Research Foundation in Ypsilanti, USA. The discussion here relates only to a part of this wider research and focuses upon the aims and contents of Polish language teaching in grades I—III of the Polish primary school.  相似文献
