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.     

新环保法视角下环保NGO公益诉讼分析

2014年新修订的环保法赋予了环保NGO公益诉讼的主体资格,可以说是环境公益诉讼史上的一座里程碑。本文通过对近年来环保NGO参与环境公益诉讼面临问题及原因的分析,提出:由于新环保法相关条款的限制性规定、公益诉讼原告诉求保障不足、我国环保NGO自身能力较弱等原因,环保NGO在新环保法颁布后参与环境公益诉讼仍可能面临一定的阻力。应该完善新环保法相关公益诉讼条款、出台激励环保NGO参与环境公益诉讼的具体措施、加强环保NGO的能力建设,以促进新环保法的有效施行。     

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.     

Relation between the skew-rank of an oriented graph and the independence number of its underlying graph

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.     

母国区域制度质量对民营企业海外市场进入模式的影响

  海外市场进入模式是跨国企业实现国际化战略目标的重要战略决策。虽然国内外学者已经意识到制度因素对新兴市场跨国企业海外市场进入模式的影响，但大多集中在对东道国制度环境影响的研究，很少考虑母国区域制度环境的复杂性，且缺乏相应的实证检验。         在此背景下，基于制度理论和社会资本理论，探讨母国区域制度质量对中国民营企业海外市场进入模式的影响机理。以规制差异和文化差异为调节变量，以社会资本为中介变量，构建母国区域制度质量与民营企业海外市场进入模式之间关系的概念模型，并以2015年进行海外市场投资的210家中国民营上市企业为研究对象进行实证研究。         研究结果表明，①母国区域制度质量与民营企业海外市场进入模式呈正相关关系，即所处的母国区域制度质量越好，民营企业更倾向于选择独资的海外市场进入模式；②母国与东道国间的规制差异和文化差异负向调节母国区域制度质量与民营企业海外市场进入模式的正向关系；③社会资本对母国区域制度质量与民营企业海外市场进入模式的关系起部分中介作用，即民营企业获得的社会资本越多，对市场信息等方面的把控能力越强，越倾向于采用独资的海外市场进入模式。         研究结果展现了中国市场分割情景下民营企业海外市场进入模式的独特性，拓展了国际商务领域对新兴国家制度环境的理解和认识，促进了制度理论和社会资本理论在国际商务领域的应用和发展。在管理实践中，民营企业在进行海外市场进入模式决策时，应充分考虑其所在的区域制度环境，同时也要善于构建不同类型的社会资本，以提高企业战略决策的可靠性和有效性。     

四川盆地中三叠世盐盆分布与演化特征研究

四川盆地卤水分布广泛，资源丰富, 早为世人所瞩目，中三叠统雷口坡组是四川盆地最早开采天然气和盐卤的层系之一。根据盆地雷口坡组大量钻井资料研究表明，盆地雷口坡组主要成盐期分别为雷三2 期和雷四2 期，在盆地东部和南部由于受到古隆起的影响，盐岩地层已被剥蚀难以保存，现今盐岩主要分布在开江古隆起和泸州古隆起的西部以及天井山古隆起的南部（华蓥山以西—龙门山以东的川西—川中地区）。印支运动对盆地雷口坡组盐岩在平面的迁移起着十分重要的作用，根据不同时期盐岩统计数据看，两期盐盆在平面上具有向西迁移、叠加的特征，其中川中的GS1 井就钻遇了这两期的盐岩。     

巴斯卡与吉登斯思想的相似性比较

同为英国当代著名的学者,巴斯卡与吉登斯的思想存在着许多相似之处。他们都重视本体论;他们都试图整合结构—能动性关系;他们都努力追求人类的解放。通过对二者思想相似性的比较,可以更为深入地了解了他们理论的异同,推动了不同学科理论之间的互动。
