目击时间的深渊——《野蔷薇》及其他

《野蔷薇》颇富思辨色彩,比较自觉集中地表达了那一时期茅盾的"时间哲学",同时比较早地提出了反思现代性这一历史课题.迁移与错位、直线与循环、潜隐与彰显等诸时间形态的对立与连接构成了文本的内在的叙事理路,也彰显了作者时间意识的深厚蕴含.     

增程式混合动力集装箱龙门起重机能量智能控制策略

针对集装箱龙门起重机的具体工况需求和特点,构建一种适用于集装箱龙门起重机的增程式混合动力系统,提出并分析该动力系统的能量智能控制策略,设计相应的智能控制模型.通过以动力电池组的荷电状态（State Of Charge, SOC）和集装箱龙门起重机运行能量需求为模糊输入,以动力电池组的充电功率为模糊输出,实现了对增程式混合动力系统的智能控制.仿真结果验证了该控制策略和控制模型的可行性和有效性.     

The majority influence on interminority attitudes: The secondary transfer effect of positive and negative contact

Among minority members, positive contact with the majority was previously found to improve not only the attitudes toward the majority but also the attitudes toward minority outgroups (the secondary transfer effect; STE). However, the roles of negative intergroup contact and minority groups’ social status in the STE have not been yet examined. Therefore, in the present study, we investigated the association between both positive and negative contact with the national majority group (Finns) and mutual attitudes among high-status Estonian (n = 171) and low-status Russian (n = 180) immigrants in Finland. Two mediators of the STE were tested: attitudes toward the majority (attitude generalization) and public collective self-esteem (diagonal hostility). While positive and negative STEs emerging via attitude generalization were expected to occur among both immigrant groups, the mediating effect of public collective self-esteem was assumed only for members of the low-status group. In both immigrant groups, the relationship between positive contact with the majority group and attitudes toward the other immigrant group was positive and indirect through more favorable attitudes toward majority group members. The same mechanism characterized negative contact, where the indirect effect was mediated by less positive attitudes toward Finns. As predicted, public collective self-esteem mediated the effects of positive and negative contact with majority group members on attitudes toward the other minority only among low-status Russian immigrants. The results call for the acknowledgement of different mechanisms explaining the STE among minority groups enjoying different social statuses in host society.

不同强度骑车和跑步的能量消耗与底物代谢特征研究

目的:研究比较不同强度骑车和跑步的能量消耗与底物代谢特征。方法:10名普通女大学生分别以45%、55%、65%、75%.VO2max强度进行骑车和跑步运动,采用气体代谢法测定机体的能量代谢状况。结果:1)骑车时,脂肪的消耗量和供能量在55%V.O2max强度达到最高,分别为4.26mg/min/kg和38.38cal/min/kg。跑步运动时,脂肪的消耗量和供能量在55%V.O2max强度达到最高,分别为6.41mg/min/kg和57.65cal/min/kg;2)在45%、55%、65%、75%V.O2max强度,跑步脂肪氧化量、总供能量、脂肪供能比例均高于骑车;而跑步的糖消耗量和呼吸交换率低于骑车。结论:1)无论骑车还是跑步,在45%、55%、65%、75%V.O2max4个运动强度中,55%V.O2max强度运动时的脂肪的氧化和供能量最大;2)在相同运动强度(%V.O2max)下,跑步总能量消耗、脂肪消耗和脂肪供能比例高于骑车,糖的消耗低于骑车。     

世界竞技体操优势转移过程的特征及其影响因素分析

世界竞技体操优势转移经历了欧洲国家交错统霸、日苏对抗、苏联领军多国并进、从多国争霸到中美抗衡等4个阶段.表现出单项化趋势越来越明显、优势集中依然突出、曾经获得过竞争优势的国家容易重新崛起、优势国家的展现在性别上有差异等4个显性规律.研究表明,竞技能力直接决定着优势的获取;创新与训练足提高竞技能力并获取优势的唯一路径;科研与资金是保证训练和实现创新的重要保障;政策导向使科技与资金支持通畅便利,群众基础为科技与资金支持提供了广阔的发展空间;地理足竞技体操存在的最低限度,政治直接影响着政策导向,经济通过政策导向间接支撑着竞技体操的发展,文化则直接影响着包括竞技体操在内的体育运动的发展方向.     

农业转移人口市民化微观决策机制研究?

借鉴成本收益理论,基于农业转移人口市民化意愿和经济理性的微观视角,构建我国农业转移人口市民化微观决策机制理论模型,并根据在重庆进行的实地调查数据进行实证检验。研究表明：农业转移人口在城市就业创业收入及其社会网络、文化程度以及农业生产成本和农村建房成本与转户迁移人数正相关,而城市劳动力素质、城市住房价格、城市日常生活开支与转户迁移人数负相关。农业转移人口在城市稳定就业后,根据转户迁移的收益与成本评估进行市民化决策,只有收益大于成本时才进行转户迁移;否则会继续“流而不迁”或返回农村。因此,仅仅拆除城乡户籍制度的藩篱并不能促成农业转移人口的快速市民化,还必须有效提高农民转户迁移的收益,并降低其成本。     

A new footwear technology to promote non-heelstrike landing and enhance running performance: Fact or fad?

This study sought to compare the kinetics and kinematics data in a group of habitual shod runners when running in traditional running shoes and newly designed minimalist shoes with lug platform. This novel footwear design claims to simulate barefoot running and reduce energy loss during impact. We compared footstrike angle (FSA), vertical average (VALR) and instantaneous (VILR) loading rates, energy loss and initial vertical stiffness between two shoe conditions. Runners demonstrated a decreased FSA while running in minimalist shoes with lug platform than traditional shoes (P = 0.003; Cohen’s d = 0.918). However, we did not observe a landing pattern transition. VALR and VILR between two footwear conditions showed no significant difference (P = 0.191–0.258; Cohen’s d = 0.304–0.460). Initial vertical stiffness (P = 0.032; Cohen’s d = 0.671) and energy loss (P = 0.044; Cohen’s d = 0.578) were greater when running in minimalist shoes with lug platform. The results show that minimalist shoes with lug platform reduce the FSA but may not lead to a landing pattern switch or lower vertical loading rates. Interestingly, the new shoe design leads to a greater energy loss than traditional running shoes, which could be explained by a higher initial vertical stiffness.
