价值论:文艺美学研究的新走向     

邹正昌  达村人 《湖南城市学院学报》2000,(2):20-24

人类所进行的一切活动,从根本上说都是一种价值活动,都是为了满足人类生存和发展的需要。文艺创作的实质就是审美价值的创造,其主要目的就是为了满足创作主体和接受主体的审美需要,求得精神的愉悦。用价值论来指导文艺美学的研究,体现了文艺美学研究的新走向,必将开拓出文艺美学研究的新境界。  相似文献

Kinematics of the field hockey penalty corner push-in     

Kerr R  Ness K 《Sports biomechanics / International Society of Biomechanics in Sports》2006,5(1):47-61

The aims of the study were to determine those variables that significantly affect push-in execution and thereby formulate coaching recommendations specific to the push-in. Two 50 Hz video cameras recorded transverse and longitudinal views of push-in trials performed by eight experienced and nine inexperienced male push-in performers. Video footage was digitized for data analysis of ball speed, stance width, drag distance, drag time, drag speed, centre of massy displacement and segment and stick displacements and velocities. Experienced push-in performers demonstrated a significantly greater (p < 0.05) stance width, a significantly greater distance between the ball and the front foot at the start of the push-in and a significantly faster ball speed than inexperienced performers. In addition, the experienced performers showed a significant positive correlation between ball speed and playing experience and tended to adopt a combination of simultaneous and sequential segment rotation to achieve accuracy and fast ball speed. The study yielded the following coaching recommendations for enhanced push-in performance: maximize drag distance by maximizing front foot-ball distance at the start of the push-in; use a combination of simultaneous and sequential segment rotations to optimise both accuracy and ball speed and maximize drag speed.  相似文献   

Factors associated with concussion-symptom knowledge and attitudes toward concussion care seeking in a national survey of parents of middle-school children in the US

Background:Developing appropriate concussion prevention and management paradigms in middle school(MS)settings requires understanding parents’general levels of concussion-related knowledge and attitudes.This study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children(aged 10-15 years).Methods:A panel of 1224 randomly selected U.S.residents,aged ≥18 years and identifying as parents of MS children,completed an online questionnaire capturing parental and child characteristics.The parents’concussion-symptom knowledge was measured using 25 questions,with possible answers being“yes”,“maybe”,and“no”.Correct answers earned 2 points,“maybe”answers earned 1 point,and incorrect answers earned 0 point(range:0-50;higher scores=better knowledge).Concussion care-seeking attitudes were also collected using five 7-point scale items(range:5-35;higher scores=more positive attitudes).Multivariable ordinal logistic regression models identified predictors of higher scores.Models met proportional odds assumptions.Adjusted odds ratios(aORs)with 95%confidence intervals(95%CIs)(excluding 1.00)were deemed statistically significant.Results:Median scores were 39(interquartile range:32-44)for symptom knowledge and 32(interquartile range:28-35)for care-seeking attitude.In multivariable models,odds of better symptom knowledge were higher in women vs.men(aOR=2.28;95%CI:1.71-3.05),white/non-Hispanics vs.other racial or ethnic groups(aOR=1.88;95%CI:1.42-2.49),higher parental age(10-year-increase aOR=1.47;95%CI:1.26-1.71),and greater competitiveness(10%-scale-increase aOR=1.24;95%CI:1.13-1.36).Odds of more positive care-seeking attitudes were higher in white/non-Hispanics vs.other racial or ethnic groups(aOR=1.45;95%CI:1.06-1.99)and in older parental age(10-year-increase aOR=1.24;95%CI:1.05-1.47).Conclusion:Characteristics of middle school children’s parents(e.g.,sex,race or ethnicity,age)are associated with their concussion-symptom knowledge and care-seeking attitudes.Parents’variations in concussion knowledge and attitudes warrant tailored concussion education and prevention.  相似文献

Habituation: A Method for Cultivating Starting Points in the Ethical Life     

Jeannie Kerr 《Journal of Philosophy of Education》2011,45(4):643-655

The Aristotelian concept of habituation is receiving mounting and warranted interest in educational circles, but has also been subject to different lines of interpretation and critique. In this article, I bring forward Aristotle's words on habituation, and then clarify the two lines of interpretation that have developed in the contemporary philosophical literature. I argue that the mechanical interpretation contains an intellectualist bias and then argue a cognitivist view that positions habituation as the only method appropriate to cultivating the starting points of the ethical life. I contend, contrary to the popular view, that the starting points are non‐discursive and not subject to explanation, and thus require the non‐discursive method of habituation. I conclude with some thoughts for moral education that answer critiques of habituation concerning the role of reasoning and critical independence of students.  相似文献
