杜甫《登高》诗中的乐观主义精神探微

杜甫写于唐大历二年(767年)秋天的《登高》诗,虽是其晚年凄凉与孤独生活状态的真实写照,但诗中却充满着令人激动的气势.这种气势不仅源于杜甫对登高文学传统的继承,亦是其晚年面对迁逝之感时昂扬生命意识的展现.除了感时伤事,诗中还深刻蕴含着杜甫晚年的壮阔情怀以及乐观主义精神,这种精神与夔州相对安定的生活有着密切关联,更是其儒家思想的重要体现.     

湘鄂川黔革命根据地的“扩红运动”及其历史与现实意义

湘鄂川黔革命根据地是长江南岸的最后一块红色根据地,是在全国其他各路红军离开原有根据地后,由红二、六军团会师后建立的,为我国革命战争的胜利起到了不可忽视的作用。文章以"扩红运动"为研究维度,从三个方面进行深刻论析。面对国民党的"围剿"、根据地内反动势力的迫害以及薄弱的地方武装力量,"扩红运动"的组织发动显得迫切需要。"扩红运动"的组织发动不仅对打击封建反动势力、维护苏维埃政权、壮大革命队伍、策应红军长征,以及保卫土地革命成果、扩大中国共产党的影响有着重要的历史意义,而且还对当今密切党群关系、处理民族关系、加强军队建设等都有着重要的现实意义。     

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.     

论历史演义的虚构性

明清时期对历史演义的性质存在着争议,有些评论家认为历史演义是正史的通俗版,因而极力反对在历史演义中进行虚构。但大量的创作实践证明,为了增强作品的可读性,历史演义不可能句句依傍正史,必然在细节描写、心理刻画、语言描写、环境烘托等方面进行虚构,从而使历史演义成为虚实结合的历史小说。

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     

春秋时期的媵制及其盛行原因

媵制指一个贵族男子娶妻 ,这个妻的侄、娣 (妹 )也随同她一同陪嫁 ,这侄娣随姑、姊同嫁一夫的婚俗 ,在春秋时期的诸侯和士大夫中相当盛行 ,对春秋时期的政治联盟、社会稳定和婚姻外交起过十分重要的作用。这种制度的盛行 ,不仅与史前文化的遗存及西周春秋时期的宗法继承制有关 ,而且与春秋时期特殊的历史背景和现实需要有关
