论第三种法治

人类社会历史中存在过三种法治.一是以法治国的法治,指统治者用法律来统治,法律是统治者手中的统治工具,统治权力的根据是统治者.二是依法治国,指法律统治着国家,统治者根据法律获得其统治权力,并且依照法律进行统治,统治权力来源于法律.但是,依法治国的法治也有两种,一种是以权力为本位,权力意味的是支配和强制;另一种是以权利为本位,权利意味的是自主和自由.于是就有了第三种法治,即以权利为本位而赋予、尊重和维护着权利的法律来统治,由这样的法律成为国家的统治者.

技巧啦啦操运动员核心力量训练内容及其方法的研究

技巧啦啦操在国内快速的普及,大大小小的比赛也越来越多,从幼儿园到大学各种各样的技巧啦啦操队伍也应运而生,参与比赛的人说也是逐年增加,但运动员的技巧水平还有待提高,身体素质也有待加强。鉴于这些薄弱方面,本文主要运用文献资料法、访谈法、逻辑分析法等对技巧啦啦操运动员的核心力量训练内容及其方法进行研究,旨从理论中指导实践,从实践中总结经验,推动我国的技巧啦啦操水平向世界先进水平迈进,从而走得更远。     

主客观信息融合的港口综合能源系统评价指标体系

为建立绿色港口,实现港口的节能环保,对港口综合能源系统(port integrated energy system,PIES)的评价方法进行研究,提出一种主客观信息融合的PIES评价指标体系,将主观评价与数理统计模型进行结合,兼顾评价过程中的主客观因素,并采用基于马氏距离的统计检验方法对评分矩阵进行修正,实现对PIES的全面评价。通过青岛港董家口港区的调研数据,验证该方法的有效性。     

中美环境监督管理体制比较研究及启示

随着我国社会经济发展,环境保护问题得到社会各界的重视,我国逐渐建立起环境监督与管理体制。美国是发达国家的典型代表,已经建立起相对完善的环境保护法体系和环境监督管理体制,值得我国学习与借鉴。文章通过分析中美环境监督管理体制的特点,比较中美两国环境监督管理机构的职责、独立性、资源配置,以及两国民众环境保护意识的差异,提出了完善我国环境监督管理体制的建议。     

基于无人机激光点云的树障检测与砍伐树木数量估算

电力走廊的树木生长会对输电线路的安全运营造成巨大影响,精确检测出影响线路安全的树木并将其砍伐至关重要。因此,提出一种基于无人机激光点云的树障检测与砍伐树木数量估算方法。首先,对激光点云进行快速自动化处理,先后精确提取地面点、电力线点与植被点;其次,基于电力线点进行分段,并分析电力线与植被点的安全距离,进而确定树障区域的位置和范围;最后,对树障区域植被点云进行单木分割,并统计单木数量,最终实现砍伐树木数量的精准估算。研究结果表明,无人机激光点云可以实现输电通道树障的有效检测与砍伐树木数量的精确估算,总体树木砍伐数量估算精度可达92.3%,可为输电线路安全运营提供遥感技术支撑,也可为电网运维单位制订树木砍伐计划提供可靠依据。     

论破产申请主体

破产申请是启动破产程序的先决条件.我国现行破产法在破产申请主体的范围上仅规定破产案件的当事人即债权人和债务人享有破产申请权.从破产法实施的实际情况来看,这种破产制度有很大的缺陷,造成该破不破、破产欺诈、债权人利益受损、国有资产流失等诸多负面后果.鉴于此,本文立足于本国国情,借鉴各国破产立法例,对我国破产申请主体的范围提出了自己的观点和建议,以期为我国的破产法立法提供一些有益的参考.     

Validity and reliability of a linear positional transducer across commonly practised resistance training exercises

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R² values of >0.85 for all variables excluding deadlift mean velocity (R² = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.     

Influence of upright versus time trial cycling position on determination of critical power and W′ in trained cyclists

Body position is known to alter power production and affect cycling performance. The aim of this study was to compare mechanical power output in two riding positions, and to calculate the effects on critical power (CP) and W′ estimates. Seven trained cyclists completed three peak power output efforts and three fixed-duration trial (3-, 5- and 12-min) riding with their hands on the brake lever hoods (BLH), or in a time trial position (TTP). A repeated-measures analysis of variance showed that mean power output during the 5-min trial was significantly different between BLH and TTP positions, resulting in a significantly lower estimate of CP, but not W′, for the TTP trial. In addition, TTP decreased the performance during each trial and increased the percentage difference between BLH and TTP with greater trial duration. There were no differences in pedal cadence or heart rate during the 3-min trial; however, TTP results for the 12-min trial showed a significant fall in pedal cadence and a significant rise in heart rate. The findings suggest that cycling position affects power output and influences consequent CP values. Therefore, cyclists and coaches should consider the cycling position used when calculating CP.
