图书馆流通业务外包的质量控制简

图书馆流通业务外包是近年来逐渐引起学界关注的问题。现有研究更多关注流通业务外包的概念内涵、必要性等问题,忽视了对流通业务外包的质量控制研究。文章通过对流通业务外包实践中存在问题的分析,指出应从严格招投标程序、加强过程控制、同外包公司密切沟通、建立读者服务评价反馈体系等方面,加强对图书馆流通业务外包的质量控制。     

考试作弊的成本分析及其控制

人是理性的利益行为者,人从事某种行为会考虑其相应的收益。目前考试作弊的现象愈演愈烈,是由于考生考试作弊的收益远远大于其所付出的成本。通过提高考试作弊的成本可以控制考试作弊行为的发生。

完善我国上市公司内部控制的对策思考

世界经济一体化的加剧,国际规则对我国的约束力也进一步加强;同样,国际内部控制的理论和实务对我国上市公司内部控制也产生重大的影响.但我国无论是内部控制规范的制定还是企业内部控制实务水平,都与美国等发达国家存在重大差距,成为我国上市公司快速健康发展的瓶颈.基于此,本文首先对我国上市公司内部控制现状作以分析;其次,介绍美国SOX法案对上市公司的影响及我们借鉴的必要性;最后,在借鉴美国SOX法案及最新内控理论基础上提出完善我国上市内部控制的对策.     

Motor control of practice and actual strokes by professional and amateur golfers differ but feature a distance-dependent control strategy

Abstract

We explored how practice and actual putting strokes differed between professionals and high-level golf amateurs, and how practice strokes reflected subtle differences in putting distances. We analysed swing amplitude, impact velocity, and acceleration profile of the club-head. The acceleration profiles showed that the motor control pattern of the practice stroke differed from that of the actual stroke. To clarify the effects of different putting distances on the practice stroke and to analyse how much the actual stroke could be explained by the practice stroke, we conducted individual regression analyses. The practice strokes of all participants could be divided into three strategies and five types by the coefficient of determination and the slope. This implies that the purpose of the practice stroke varied among golfers. Most golfers used the individual velocity criteria in their practice strokes, which resulted in different putting distances based on their criteria. Unexpectedly, we found no significant difference in skill level between professionals and high-level amateurs. The results of this study imply that the practice stroke does not duplicate the actual stroke, even for professional golfers with excellent skills. However, most high-level golfers adopted distance-dependent control strategies for slightly different putting distances.     

Emerging hemostatic materials for non-compressible hemorrhage control

Non-compressible hemorrhage control is a big challenge in both civilian life and the battlefield, causing a majority of deaths among all traumatic injury mortalities. Unexpected non-compressible bleeding not only happens in pre-hospital situations but also leads to a high risk of death during surgical processes throughout in-hospital treatment. Hemostatic materials for pre-hospital treatment or surgical procedures for non-compressible hemorrhage control have drawn more and more attention in recent years and several commercialized products have been developed. However, these products have all shown non-negligible limitations and researchers are focusing on developing more effective hemostatic materials for non-compressible hemorrhage control. Different hemostatic strategies (physical, chemical and biological) have been proposed and different forms (sponges/foams, sealants/adhesives, microparticles/powders and platelet mimics) of hemostatic materials have been developed based on these strategies. A summary of the requirements, state-of-the-art studies and commercial products of non-compressible hemorrhage-control materials is provided in this review with particular attention on the advantages and limitations of their emerging forms, to give a clear understanding of the progress that has been made in this area and the promising directions for future generations.     

专用性投资类型、治理机制与海外知识获取的关系研究

本文从知识复杂度出发,探索代工专用性投资类型(资产类专用性投资和人力资本类专用性投资)与治理机制的匹配关系对海外知识获取的影响。应用AMOS17.0和SPSS16.0对229个中国代工企业样本数据进行实证检验,结论显示:(1)不同治理机制对不同类型专用性投资与海外知识获取关系具有不同的调节效应。具体来看,合同治理与资产类专用性投资的交互作用对海外知识获取有积极影响,关系治理与人力资本类专用性投资的交互作用对海外知识获取有积极影响,而不合理的匹配关系(即合同治理VS人力资本类专用性投资;关系治理VS资产类专用性投资)对海外知识获取的影响是不显著的。(2)专用性投资类型与治理机制的匹配效应随知识复杂度的变化而变化。具体来看,在知识复杂度较低的情况下,合同治理与资产类专用性投资的交互作用对海外知识获取的促进作用更显著。在知识复杂度较高的情况下关系治理与人力资本类专用性投资的交互作用对海外知识获取的促进作用更显著。上述研究阐明了代工专用性资产类型、治理机制和知识复杂度的匹配关系对海外知识获取的影响,有助于指导代工企业依据专用性资产类型和知识复杂度选择适宜的治理机制,进而获取更好的海外知识获取绩...

外部冲击频发期的宏观经济政策空间

宏观经济治理现代化,首要任务是与经济发展阶段相匹配、与经济现实相适应,持续不断地服务于经济现代化进程。一定时期的相对稳定和关键时期的转型创新,以及相应的法治约束和理论支撑,是各国宏观经济治理现代化的共同特征。中国宏观经济治理经历了相对稳定和转型创新相互交替的三个发展阶段,表现出目标多元化、工具多样化和理念系统化的鲜明特征。中国宏观经济治理的基本经验是,既要尊重经济现代化的一般规律,又要尊重本国经济的初始条件,创新的同时也要有所继承。在新的历史时期,中国宏观经济治理面临严峻挑战,需要统筹和协调多重冲击下的多目标多政策系统,因此,一方面要加快宏观经济治理立法,尽快进入下一个相对稳定期,以更好应对“新三期叠加”;另一方面要加快理论创新和理论构建,凝聚共识,增加透明度,减少对政策的误解和政策实施中的摩擦。     

我国区域政府间大气污染协同治理的制度基础与安排

大气污染逐渐成为区域公共事务治理的重要领域,为实现更有效的治理,中国在组织建设方面进行了有益探索,形成了多样化的组织形态,而如何理解这些组织的类型差异和选择逻辑成为科学评价和优化的理论问题。大气污染的协同治理组织,是在面对不同的大气污染治理和集体行动需求时,在充分考虑组织有限理性和资源约束的情况下设立的高效协作的多样化政府机构间合作网络。基于“职能—周期”二维分类框架,中国目前的大气污染协同治理组织可划分为综合常设、常设单一、单一应急以及应急事件四类。本文结合典型政策文件与法律依据,从组织结构形态、结构配置以及协同运作等方面总结了不同类型组织的政策导向、结构特征和形成逻辑,并对如何进一步优化不同类型组织的功能与建设提出建议。
