新时期下“体教结合”的理念及其重构

体教结合是牵动中国体育体制与教育体制改革的战略性问题,它应伴随着我国政治、经济、文化发展而演进,不能局限于竞技体育与教育的结合,它应该是学校体育、竞技体育、社会体育与教育的结合,教育也不能局限于学校。通过对新时期下体教结合内涵的重新诠释,给出新时期对体教结合实施的重新定位,为进一步完善我国的体教结合提供理论参考。

Maternal history of child maltreatment and maternal depression risk in the perinatal period: A longitudinal study

Existing research is limited, with only a few studies considering each single type and multiple types of child maltreatment (CM) as well as multiple assessments of maternal depression throughout the perinatal period. The purpose of the study was to assess each type and accumulative types of CM in relation to the risk of maternal depression throughout the perinatal period. In total, 276 pregnant women were recruited from the prenatal clinic at a general hospital in China. Maternal CM history and depression risk were assessed at late pregnancy, postpartum week 1, and postpartum week 4 using the Childhood Trauma Questionnaire (CTQ) and Edinburgh Postnatal Depression Scale (EPDS). The GEE showed that physical and emotional neglect and multiple types of CM were associated with higher overall depression risk across the perinatal period. The multinomial regression models showed physical neglect and multiple types of CM predicted higher risk of both antepartum and postpartum depression. Emotional and sexual abuse and emotional neglect predicted antepartum depression risk, while none of the three types of CM predicted postpartum depression risk. Physical abuse did not predict antepartum and postpartum depression risk. The findings suggest that maternal history of child physical and emotional neglect play significant roles in perinatal depression risk with physical neglect as the most important predictor. Routine screening for maternal CM history and depression risk in prenatal clinics is needed to aid in the early detection and treatment of depression.     

突发性公共危机信息传播模式的时段性特征及管理对策

在界定突发性公共危机的定义和分类以及综述各种信息传播理论模式的基础上，结合突发性公共危机信息传播的特点，并参照Defleur的“互动过程模式”和Fiona Duggan及Linda Banwell的危机信息传播模式，提出基于信息流强弱的突发性公共危机信息传播模式。在此基础上分析信息传播过程的时段性特征，并针对所提出的模型和5个阶段的特征对政府如何有效应对突发性公共危机的管理对策进行探讨。     

Impact absorption of tennis shoe-surface combinations

The aim of this study was to investigate, for typical shoes and surfaces used in tennis, the relative role of the shoe and surface in providing cushioning during running. Five test surfaces ranging from concrete to artificial turf were selected, together with two shoe models. Impact absorbing ability was assessed mechanically using drop test procedures and biomechanically using peak magnitude and rate of loading of impact force and peak in-shoe pressure data at the lateral heel. Differences in biomechanical variables between shoe-surface combinations were identified using a two-way ANOVA (p < 0.05). Mechanical test results were found to rank the surfaces in the same order regardless of the shoe model, suggesting that the surface is influential in providing cushioning. However, for all mechanical and biomechanical (p < 0.05) variables representing impact absorbing ability, it was found that the difference between shoes was markedly greater than the differences between surfaces. The peak heel pressure data were found to rank the surfaces in the same order as the mechanical tests, while impact force data were not as sensitive to the changes in surface. Correlations between mechanical and biomechanical impact absorption highlighted the importance of testing the shoe-surface combination in mechanical tests, rather than the surface alone. In conclusion, mechanical testing of the shoe-surface combination was found to provide a strong predictor of the impact absorbing ability during running if pressure data were used. In addition, for typical shoe-surface combinations in tennis, the shoe was found to have more potential than the surface to influence impact loading during running. Finally, in-shoe pressure data were found to be more sensitive than force plate data to changes in material cushioning.
