从背井离乡到创新创业 ——兼论互联网使用对创业的作用

文章利用2016年中国劳动力动态调查(CLDS)数据探讨了外出务工经历对农民创业的影响.实证分析表明,外出务工经历显著提高了农民创业概率1.67％.使用工具变量法和倾向得分匹配法对内生性进行弱化后,上述结果仍旧稳健.并且发现异质性外出务工经历中,企业务工经历对创业行为并无显著影响,而自由工作、个体工商户等非企业工作经历则显著提升了农民创业概率,这为不同类型的外出务工经历对创业的影响提供了新的经验证据,打开了外出务工经历的"黑匣子".对外出务工影响创业的机制进一步探讨发现,外出务工经历会通过社会资本、物质资本和人力资本三个渠道提高农户创业概率,而创业动机并非其影响机制.同时,文章发现,互联网使用在一定程度上与外出务工具有类似的功能,对外出务工经历存在一定的替代效应.最后,文章研究表明外出务工经历对本地创业具有显著影响,而对外地创业的影响则不显著;相较于雇主创业,外出务工经历对自雇创业具有显著的正向影响.     

雷锋生命价值的三重维度及当代意蕴

雷锋的生命价值从历史、空间、境界三重维度上表现为延伸性、普遍性和超越性。雷锋的生命价值符合人与社会全面发展进步的需要,即符合人的超越性的要求、符合群体共同发展的要求、符合中华民族道德实践的要求、符合中国共产党的宗旨要求,是对生命为什么有价值、生命价值是什么、怎样实现生命价值问题的直接解答。     

论我国刑事诉讼中“非法证据”的界定标准

在刑事非法证据排除规则的具体运用中,"非法证据"的界定是当然前提。非法证据并非是任一证据合法性要件欠缺的广义非法证据,而专指取证主体通过严重非法的手段或者侵犯公民基本权利的方式所获取的证据材料。我国刑事非法证据包括非法言词证据和非法实物证据两类,两类非法证据在实际判断中虽存在差异,但都应围绕取证手段的非法性展开,分别考察取证手段是否违反法律规定以及违法的严重程度,以准确界定刑事非法证据的范围。     

20世纪二三十年代北平交际舞的散播与社会风尚嬗变

20世纪20年代,北平营业性舞场逐渐兴起,舞者队伍扩大,交际舞业"迅速极盛"。该行业在丰富城市娱乐生活的同时,却诱发了奢靡、享乐、纵欲等不良风气的蔓延,导致北平市政府一再禁舞。30年代初,北平舞业"盛极而衰"。北平的官方、民众、媒体在此间的诸般心态及举措反映了交际舞在该市散播历经波折,呈现出这一时期北平新旧观念并存、博弈的社会风貌,也说明北平的传统保守气质使其社会风尚的嬗变显现出相对迟缓的态势。从根本上说,该市的社会生态系统制约着其社会风尚变迁的深度与广度。     

Interval estimation for conformance proportions of multiple quality characteristics

A conformance proportion is an important and useful index to assess industrial quality improvement. Statistical confidence limits for a conformance proportion are usually required not only to perform statistical significance tests, but also to provide useful information for determining practical significance. In this article, we propose approaches for constructing statistical confidence limits for a conformance proportion of multiple quality characteristics. Under the assumption that the variables of interest are distributed with a multivariate normal distribution, we develop an approach based on the concept of a fiducial generalized pivotal quantity (FGPQ). Without any distribution assumption on the variables, we apply some confidence interval construction methods for the conformance proportion by treating it as the probability of a success in a binomial distribution. The performance of the proposed methods is evaluated through detailed simulation studies. The results reveal that the simulated coverage probability (cp) for the FGPQ-based method is generally larger than the claimed value. On the other hand, one of the binomial distribution-based methods, that is, the standard method suggested in classical textbooks, appears to have smaller simulated cps than the nominal level. Two alternatives to the standard method are found to maintain their simulated cps sufficiently close to the claimed level, and hence their performances are judged to be satisfactory. In addition, three examples are given to illustrate the application of the proposed methods.     

领导干部党性修养评价机制研究

建立健全领导干部党性修养评价机制,是加强党的执政能力建设,建设高素质执政骨干队伍的客观需要。坚定的政治信念、牢固的党纪意识、严谨的自律能力、优秀的道德品质和勤勉的工作作风是评价领导干部党性修养的主要内容。要明确评价领导干部党性修养的指导思想、评价主体和评价原则,要建立健全领导干部党性修养的评价指标体系,不断探索科学的评价领导干部党性修养的方式方法。

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.     

金石文献与《全宋诗》补正——以四川、江西、安徽等地金石文献为例
