Exploring Factors Influencing the Risky Cycling Behaviors of Young Cyclists Aged 15–24 Years: A Questionnaire-Based Study in China

Road traffic crashes are the leading cause of death for young people, among whom cyclists account for a higher percentage of injuries and deaths than any other road users. This study aimed to examine the factor structure of the Young Cyclist Behavior Questionnaire (YCBQ) and investigate the relationships among demographic characteristics, cycling use-related variables, perceived risk, perceived cycling skills, and risky cycling behaviors among young people. A sample of 448 cyclists (mean age of 20.37 years) completed the questionnaire. Exploratory factor analysis, confirmatory factor analysis, and structural equation modeling were utilized. The YCBQ had a clear factorial structure, items with high factor loadings, and good internal consistency. The five-factor structure included traffic violations, impulsive behaviors, ordinary violations, distractions, and errors. Risky cycling behaviors could be explained by gender, age, perceived risk, and perceived cycling skills, with the model explaining 37% of the variance. Gender had the greatest impact on risky cycling behaviors; male individuals were more likely to engage in risky behaviors. Young cyclists with higher levels of perceived risk had lower probabilities of engaging in risky cycling behaviors. Cyclists with lower scores on perceived cycling skills were more likely to report engaging in risky cycling behaviors. Age significantly explained risky behaviors; the younger the cyclist was, the higher his or her risky behaviors score. This research provides a theoretical foundation for the prevention of risky behaviors among young cyclists. Regarding intervention design, attention to the identified gender differences, the need to strengthen the ability to perceive risk, and the importance of road safety education for young cyclists may promote safer cycling.     

Synthetic data method to incorporate external information into a current study

We consider the situation where there is a known regression model that can be used to predict an outcome, Y, from a set of predictor variables X . A new variable B is expected to enhance the prediction of Y. A dataset of size n containing Y, X and B is available, and the challenge is to build an improved model for Y| X ,B that uses both the available individual level data and some summary information obtained from the known model for Y| X . We propose a synthetic data approach, which consists of creating m additional synthetic data observations, and then analyzing the combined dataset of size n + m to estimate the parameters of the Y| X ,B model. This combined dataset of size n + m now has missing values of B for m of the observations, and is analyzed using methods that can handle missing data (e.g., multiple imputation). We present simulation studies and illustrate the method using data from the Prostate Cancer Prevention Trial. Though the synthetic data method is applicable to a general regression context, to provide some justification, we show in two special cases that the asymptotic variances of the parameter estimates in the Y| X ,B model are identical to those from an alternative constrained maximum likelihood estimation approach. This correspondence in special cases and the method's broad applicability makes it appealing for use across diverse scenarios.

产量竞争下量子博弈刻划的结盟特征函数及特性

文章基于量子博弈的EWL模型的视角来计算产量竞争中三方形成联盟的特征函数,将经典策略空间扩展至量子策略空间,对量子博弈刻画的特征函数进行了分析.研究表明,在此模型下,在单独一名成员组成的联盟中使用量子策略一定比经典策略有优势;在两名成员组成的联盟中,有一名成员使用量子策略至少不会比经典策略得到的特征函数低;特别注意的是,在大联盟中,量子策略不会比经典策略优.     

China’s first priority in post-war state building: A wealthy state,or a strong army?

This analysis examined causal links in China’s defence–growth nexus in 1960–2016. The results show that better growth significantly reduces military-civilian ratio and propels military reforms. The unidirectional threshold causality from growth to defence shows that the military impact on a positive change in China’s growth is little in the long term. Conversely, the growth impact of a positive change in defence has accelerated after it reaches the threshold year in 1987. This finding explains why Chinese economy stagnated when defence was prioritised and why China has risen dramatically in the Far East after three decades of fast economic growth.     

诉讼中的言论豁免权及其界限

首先讨论诉讼中的言论豁免权问题,然后从法律世界与现实世界的隔离,以及司法所具有的吸纳社会不满的机制两个角度分析了诉讼中的言论豁免权存在的理论根据,最后对诉讼中的言论豁免权的界限进行了探讨,认为当事人的言行必须与本案有关,必须在法定程序所设定的时空范围内做出,必须符合法定程序所要求的形式要件,才能享受豁免权.

论企业党校的未来走向

胡锦涛同志在全国党校工作会议上指出 ,党校在党的建设和党的事业中历来占有重要的地位 ,发挥过重要作用。[1 ] 企业党校在过去的工作中 ,为企业培养、培训了大量建设人才 ,作出了不可低估的贡献。今天 ,在市场化取向的国企制度创新改革过程中 ,企业党校面临了前所未有的严峻挑战 ,生存和发展成了问题。企业党校的生存现状令人堪忧。一是不能完全依赖企业生存。企业发展困难 ,对党校的支持不能完全满足企业党校生存、发展的要求 ;二是不能完全依赖市场生存。职工市场的意识不强 ,师资队伍素质、结构、能力不能适应市场的要求 ,缺乏办学的独…

中国省域信贷风险判别分析

现阶段，商业银行信贷仍是我国社会资金配置的主要方式。出于盈利和风险考虑，商业银行信贷行为天然具有顺周期特征。为实现稳增长目标，政府更倾向于逆周期调节。受到地方财政收支状况影响，省级地方政府会采取不同方式、不同程度地干预省域资金配置。十九大报告明确指出，要健全货币政策和宏观审慎政策双支柱调控框架。因此，省域信贷风险判别是一个动态过程，需在经济周期与宏观审慎政策框架下整体考虑。在此背景下，本文基于新古典经济学分析框架，建立了2008年以来省域信贷风险识别模型，研究发现，第一，地方财政支出收入比与不良贷款率存在正向影响关系，资本回报率与不良贷款率存在负向影响关系，且地方财政支出收入比对不良贷款率的影响程度更大；第二，依据分类准则，属于信贷高风险的省域分别是：河南，海南，重庆，四川，贵州，云南，陕西，甘肃，青海，宁夏，新疆，西藏；第三，在地方财政支出收入比、资本回报率的显著作用影响下，我国各省域不良贷款率呈现U型变化，不良贷款率阈值为1.49%，即当不良贷款率大于1.49%时，省域贷款风险较高；第四，当我国资本回报率处于企稳阶段，不良贷款率处于低于阈值的谷底阶段，且省域间风险差异性较小。当我国资本回报率处于下行阶段时，不良贷款率上升至阈值线以上，且省域间风险差异性较大。
