Dual-effects of core enterprise management and media attention on occupational health and safety of small and medium suppliers in China

This study examines the construction of an occupational health and safety (OHS) governance model for small- and medium-sized suppliers (SMSs) impacted by the dual effects of core enterprises' management and media attention. The objective of this research is to improve the social governance effect of SMSs' OHS. Drawing on evolutionary economics, an evolutionary game model with three main players—core enterprises, SMSs, and media—is established, and the conditions of each entity's evolutionary stability strategy are analyzed. The results show that the evolution trend for any party is closely related to the strategic choices of the other two parties. Further, a model for SMSs' OHS governance with focus on core enterprise management and media attention can be effectively built by reducing the costs of core enterprise management, enhancing the probability of accurate media reporting, decreasing the OHS input cost of SMSs, increasing the expected exposure returns of the media, and reducing the media's investigation cost. This study is the first to consider the important influence of core enterprises and the media on SMSs' OHS behavior, which bridges the research gap not only from a theoretical perspective, but also a practical one.     

中国石油油气战略通道建设 与管理创新实践

油气管道是国民经济发展的能源大动脉。随着我国油气对外依存度的逐年提高,打通油气战略通道、保障能源供给成为当务之急。在陆上油气战略通道建设过程中,通过"1+N"协同式自主创新,形成了管道设计、施工、装备国产化及易凝高粘原油输送等关键技术,建成了目前总长6×104km、输送油品1.7×108t、输送天然气1.4×1011m3的大型油气管网。在大型管网运行管理过程中,通过建立e-SAME安全一致性系统,形成了运行管理组织机构、资产完整性管理、市场保障和应急维护等子系统,确保了企业安全目标地实现。     

聚羧酸型梳状共聚物的合成和超分散性能研究

以聚氧乙烯甲基烯丙基二醚(APEO-n)、顺丁烯二酸酐(MAn)、苯乙烯(St)等为共聚单体,采用不同引发剂,合成了一系列聚羧酸型梳状共聚物超分散剂,并以PEO-n单酯化得酯化产物,研究了共聚物的结构、组成、添加量等对水泥粒子分散性能的影响。结果表明：超分散剂的性能受端基效应、酯化作用、接枝链的长度和密度的影响,当接枝链长度为30时,分散性能良好。     

The moderating effect of slack resources on the relation between quality management and organisational learning

Recent literature in the field of strategic management suggests that firms must learn to combine internal competencies and resources in order to achieve competitive advantages. This paper examines how firms employ slack resources to enhance the relationship between quality management (QM) and organisational learning to obtain sustainable competitive advantages. The findings use empirical data gathered from 202 quality managers to support the hypotheses that: (1) there is a strong connection between organisational learning and QM; and (2) the relation between organisational learning and QM is moderated by slack resources.
