国外城市机场噪声治理的多元路径及其启示

20世纪80年代以来,随着中国城市发展速度的持续提升,各级各类城市机场的建设步伐也不断加快,时至今日,机场已经成为了许多城市重要的对外交通枢纽和新的城市商业中心。但以噪声污染为重要表征的负外部性输出,在中国城市机场也呈现出蔓延之势。文章通过相关文献资料梳理发现,国外对城市机场噪声的治理一般通过机场规划、降噪技术、噪声征税、制度规制、强化绿化等多种路径展开。了解国外治理城市机场噪声的实践探索,对于我们寻求中国城市机场噪声治理的未来道路,具有重要的启示和借鉴意义。     

The disembedded digital economy: Social protection for new economy employment in China

This research focuses upon employment in the new economy, exploring labour protection and social protection in the digital age in China. Through an empirical survey conducted in three Chinese cities, social insurance and the labour rights of employees in the digital economic sector, such as gig employment, e-commerce, and various other forms of online employment, have been examined in-depth. This study reveals new regulatory loopholes in the digital labour market, which have substantially eroded the basis of social policy arrangements in China, “softening” participation in social insurance branches and compliance with labour regulations remarkably. Drawing upon the theoretical concepts of Polanyi on embeddedness and disembeddedness, we argue that the digital employment sector in China has been increasingly disembedded from social institutions and social control. The new configuration in the digital field of social policy requires novel conceptual models and institutional settings to cope with increasing social risks in virtual spaces.     

A New Methodology for Before–After Safety Assessment Using Survival Analysis and Longitudinal Data

The widely used empirical Bayes (EB) and full Bayes (FB) methods for before–after safety assessment are sometimes limited because of the extensive data needs from additional reference sites. To address this issue, this study proposes a novel before–after safety evaluation methodology based on survival analysis and longitudinal data as an alternative to the EB/FB method. A Bayesian survival analysis (SARE) model with a random effect term to address the unobserved heterogeneity across sites is developed. The proposed survival analysis method is validated through a simulation study before its application. Subsequently, the SARE model is developed in a case study to evaluate the safety effectiveness of a recent red‐light‐running photo enforcement program in New Jersey. As demonstrated in the simulation and the case study, the survival analysis can provide valid estimates using only data from treated sites, and thus its results will not be affected by the selection of defective or insufficient reference sites. In addition, the proposed approach can take into account the censored data generated due to the transition from the before period to the after period, which has not been previously explored in the literature. Using individual crashes as units of analysis, survival analysis can incorporate longitudinal covariates such as the traffic volume and weather variation, and thus can explicitly account for the potential temporal heterogeneity.

私营企业女工权益保护论

在私营企业中 ，普遍存在着职工合法权益难以保障的问题，尤其是女工权益受侵害的问题更为普遍，也更 为突出。女工权益受侵害的原因，既有社会大环境方面的，也有企业主方面的，还有女工个 人方面的。制定专门的《私营企业法》，明确劳动契约原则，加强工商行政管理部门的管理 职能，加大新闻机构宣传与监督力度等，是有效保护女工合法权益的主要途径。     

论《四库总目》文学批评的经世价值取向

明末清初 ,宋明理学已经发展到极端 ,于是清初文人倡导儒家传统的经世致用思想以救理学空疏浮泛之弊 ,经世思想成为一时社会思潮的主流。《四库全书总目》的文学批评无论是功用价值论、创作主客体论还是艺术风格论都由此而带上浓郁的经世色彩

内核级并发通信的研究

提出了一种内核级并发消息通信机制。该机制采用对象传送协议和动态线程池技术,并通过会话控制完成数据的收发过程,将线程池设计为二级阻塞队列来暂缓线程的撤销过程,从而保证既能够快速响应客户请求,又可减少因频繁创建和撤销线程而消耗系统的资源和时间,为分布式操作系统提供了高效可靠的通信服务。

20世纪30年代初胡秋原的庸俗社会学批判

庸俗社会学的木质，在于无视艺术规律，取消中间环节，把文艺这一精神现象与人类社会的基础性结构直接关联，从而对文艺的性质、功能作出简单性规定和强制性要求。胡秋原是中国文论界从学理的层面．对庸俗社会学作出深入剖析的第一人。其理论资源，来自于普列汉诺夫的“中介论”。他对弗里契《艺术社会学》“图式化”弊端之批评，亦发时人所未见。其地球“自转”与“公转”之喻，表明了他对文学“自律”与“他律”关系的洞见与把握，并给后人以启发。＋
