Determinants and patterns of physical activity practice among Spanish university students     

Romaguera D  Tauler P  Bennasar M  Pericas J  Moreno C  Martinez S  Aguilo A 《Journal of sports sciences》2011,29(9):989-997

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

A Lakatosian Framework to Analyze Situations of Cognitive Conflict and Controversy in Students' Understanding of Heat Energy and Temperature     

Laburú  Carlos Eduardo  Niaz  Mansoor 《Journal of Science Education and Technology》2002,11(3):211-219

The objective of this study is to analyze secondary school students' interactions (conflicts, controversies, and arguments) as they participate in an intact classroom activity designed to facilitate their understanding of heat energy and temperature. The study is based on 32 ninth-grade students in a public school in Londrina, Brazil. Results obtained show that the differentiation between heat energy and temperature constitutes considerable difficulties for the students, and can be considered as part of the hard-core of their understanding (Lakatos, 1970, Criticism and the Growth of Knowledge, Cambridge University Press, Cambridge, UK, pp. 91–196). Student interactions (video taped) were classified into an Alternative Model, Transitional Model, and Scientific Model, depending on the degree to which they reflected a progressive transition in their hard-core. Students generally resisted a change in their conceptual understanding. Some students were able to question the hard-core of their beliefs and construct a Transitory Model. Some students experienced a further progressive transition by constructing a Scientific Model, based on the understanding that Temperature only measures the energy of agitation. Methodology used also provided a glimpse of how a particular student grappled with the conflicts in order to facilitate progressive transition in understanding. It is concluded that given the opportunity to discuss, reflect, consider alternative/conflicting situations, students can construct models that increase progressively in their heuristic/explanatory power.  相似文献   

Relational‐Cultural Theory–Based Interventions With LGBTQ College Students     

Carlos A. Flores  Angela I. Sheely‐Moore 《Journal of College Counseling》2020,23(1):71-84

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) community members can encounter daily challenges living in a heterosexist society, including the college milieu. The authors apply the tenets of relational‐cultural theory (RCT) to LGBTQ college students. Furthermore, a case study is included to highlight ways counselors can infuse RCT strategies when working with this population.  相似文献   

PISA as a Political Tool in Spain: Assessment Instrument,Academic Discourse and Political Reform     

Leoncio Vega Gil  Juan Carlos Hernández Beltrán  Eva García Redondo 《欧洲教育》2016,48(2):89-103

This study examines to what extent there is a sort of “political appropiation” by political parties when they seek to set a discourse about the Spanish PISA outcomes. We have consistently found that programs for assessing the competencies of students, especially PISA, have become tools of rationalization and the legitimization of education policies in both the national and territorial contexts. Furthermore, each regional government focuses its discourse on what it feels to be its strong points, that is, a clear “self-justifying reading” of PISA outcomes.  相似文献   

Spanish savings banks: a view on intangibles     

Carlos?Serrano-CincaEmail author  Cecillo?MarMoliero  Fernando?Chaparro 《知识管理研究与实践》2004,2(2):103-117

We study Spanish savings banks from the point of view of their efficiency, transparency in the disclosure of financial information through the net, and the provision of electronic banking services. Performance indicators are developed using data envelopment analysis and the tools of multivariate statistical analysis. The choice of indicators is framed within the theory of intangible assets. An attempt is made rank savings banks according to their level of achievement in each indicator. Savings banks are shown to be classified into four groups according to the level of achievement in the indicators of transparency and e-service. The relationship between efficiency and profitability is also discussed.  相似文献

Internalized Racism,Perceived Racism,and Ethnic Identity: Exploring Their Relationship in Latina/o Undergraduates     

Carlos P. Hipolito‐Delgado 《Journal of College Counseling》2016,19(2):98-109

For Latina/o undergraduates, ethnic identity is an important construct linked to self‐esteem and educational attainment. Internalized and perceived racism have been hypothesized to hinder ethnic identity development in Latina/o undergraduates. To assess if internalized and perceived racism were inversely related to ethnic identity, the author conducted a hierarchical linear regression with 373 Latina/o undergraduates. There was a significant relationship between internalized racism and ethnic identity. Findings indicate a need to challenge internalized racism in Latina/o undergraduates.  相似文献
