‘Teaching’ the path towards university: understanding student access through storied-futures and meritocratic grand narratives     

Neil Anthony Buddel 《British Journal of Sociology of Education》2018,39(1):16-31

The notion that the stories of our lives shape dispositions towards imagined futures is another lens through which university underrepresentation should be viewed. A storied lens attends to how futures, like university attendance, are storied during childhood to the extent that some youth imagine, and therefore plan, these futures as natural progression. Such was the case for study participants, indicating that childhood stories contain answers for mitigating social reproduction connected to parental education and cultural forces within the home. Examining social mobility through the underexplored storied-futures grand narrative presents unique solutions that lay hidden within the dominant meritocratic grand narrative.  相似文献   

Discrete Choice Modeling in Education: An Innovative Method to Assess Teaching Practices     

Vasilis Grammatikopoulos  Athanasios Gregoriadis  Michalis Linardakis 《Educational Measurement》2019,38(3):46-54

Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.  相似文献   

Parents’ son preference,childhood adverse experience and mental health in old age: Evidence from China     

《Child abuse & neglect》2019

BackgroundSon preference is an enduring phenomenon in China and may often be related to childhood adverse experiences. According to a life-course perspective, adverse experiences during a childhood period may have a long-term effect on mental health in later age. However, little is known about this relationship between parents’ son preference, childhood adverse experiences and adulthood mental health in China.ObjectiveThe study aims to evaluate the association of parents’ son preference and individual mental health in old age in China. The mediating role of childhood adverse experiences was also estimated.Participants and settingThe China Health and Retirement Longitudinal Study (CHARLS) 2015 combined with CHARLS life history survey was analyzed (N = 11,666).MethodsMental health was measured by a shortened modification of the Center for Epidemiologic Studies Depression scale including seven items, and higher scores indicated worse mental health status. A four-step mediating model was applied.ResultsRespondents growing in families with son preference had on average 0.75 (P < 0.001) points higher on the mental health scale than their counterparts, and the effects were consistent for both males and females. Childhood adverse experiences measured by physical maltreatment, emotional adverse experiences and witnesses of inter-parent violence mediated the relationship between parents’ son preference and individual adulthood mental health by 47.87%. For females, physical maltreatment and emotional adverse experiences explained the most parts of health effects of parents’ son preference, whereas witnesses of inter-parent violence was the most influential mediator for males.ConclusionParents’ son preference led to adverse childhood experiences, which influenced mental health in adulthood.  相似文献   

大学生隐形肥胖运动处方的实验研究   总被引：1，自引：0，他引：1  

张秀丽  王群  王凌娟  肖国强 《广州体育学院学报》2004,24(3):38-40,50

隐形肥胖在日本已有较多的研究，在我国尚未见报道。笔者认为，我国大学生隐形肥胖的比例低于日本，主要与研究对象的饮食文化有关；隐形肥胖运动处方的制定，应以全身有氧运动控制体重为原则，运用局部动、静力练习减少多余脂肪，增加瘦体重为目标。  相似文献   

脂肪细胞因子与肥胖及能量代谢的研究进展     

周春柳 《体育科技》2005,26(2):52-55

脂肪细胞是能量储存细胞,也是活跃的内分泌细胞。现已发现人类脂肪细胞分泌几十种脂肪细胞因子,它们对机体的能量代谢及脂肪积累具有显著的调节功能。重点阐述在机体能量代谢平衡调控中起主要作用的脂肪细胞因子,并通过分析脂肪细胞因子对机体能量代谢的调节作用与肥胖之间的关系,为运动减肥和糖尿病的运动治疗提供了新的研究方向。  相似文献   

运动减肥机制探析———酰化刺激蛋白的作用及其调节   总被引：2，自引：0，他引：2

改善单纯性肥胖儿童血压血脂水平的运动处方研究   总被引：5，自引：0，他引：5  

徐秀英  李骁君  刘迅雷  陈树良  王明燕 《山东体育科技》2004,26(4):17-19

对20名单纯性肥胖儿童进行了血压、血脂(TC：用酶反应试剂药盒测定，TG：乙酰丙酮微量测定法)检测，并对10名儿童进行了8周的耐力训练(训练中未对受试者提出低盐、低脂的饮食要求)。结果表明：8周的耐力训练后，肥胖儿童血清中血脂(TG)含量下降，HDL—C显著上升，血脂代谢紊乱得到缓解，同时血压有明显下降。从众多因素的分析中发现，TG与SBP(r=0．32)、DBP(r=0．22)呈正相关，而ApoAI与SBP(r=-0．19)、DBP(r=-0．20)呈负相关，提示单纯性肥胖儿童的高血压与其血脂代谢紊乱有关。非饮食干预条件下的耐力训练有助于降低肥胖儿童的血压、血脂。  相似文献
