社会网络对民间金融风险的影响已被广泛认可,但是,究竟什么样的网络结构有抑制风险的作用,什么样的网络结构有扩增风险的作用?以资金互助会为例,将互助会涉及的社会网络按结构特征分为单个会的会内网络和多个会的会间网络,研究可知:(1)越紧密的会内网络结构以及越大的网络规模越有利于民间金融风险的控制。(2)跨会网络具有抑制和扩增风险两种作用,它是协同监督和惩罚机制生效的基础,因而对风险具有控制作用,但这种作用只在中介成员为会首时才显著;同时,它也构成了风险传播的通道,导致资金被分散到多个会中,因而提升了系统性风险。 相似文献

“作为生活艺术的哲学”已成为当代欧洲思想界的一个热点,对哲学的这种理解和实践与20世纪的现象学运动密不可分。无论是胡塞尔的生活世界,还是海德格尔的此在分析,都是以关怀人类生存、合理安顿人与世界的关系为根本动机的。现象学对理论和实践关系的倒置、对在场和缺席关系的倒置、对确定性和可能性的倒置、对必然性和偶然性的倒置,为生活艺术哲学做了充分的理论奠基,由此出发,生活艺术哲学在哲学实践、审美泛化等向度上得到了发展。现象学的“小零钱”精神、“前科学”立场、关注意义构建、重回古典哲学的精神和实践,都成为生活艺术哲学的基本立场。 相似文献

A ship that is not under control (NUC) is a typical incident that poses serious problems when in confined waters close to shore. The emergency response to NUC ships is to select the best risk control options, which is a challenge in restricted conditions (e.g., time limitation, resource constraint, and information asymmetry), particularly in inland waterway transportation. To enable a quick and effective response, this article develops a three‐stage decision‐making framework for NUC ship handling. The core of this method is (1) to propose feasible options for each involved entity (e.g., maritime safety administration, NUC ship, and ships passing by) under resource constraint in the first stage, (2) to select the most feasible options by comparing the similarity of the new case and existing cases in the second stage, and (3) to make decisions considering the cooperation between the involved organizations by using a developed Bayesian network in the third stage. Consequently, this work provides a useful tool to achieve well‐organized management of NUC ships. 相似文献

目前扣除系数的计算方法主要为分析法与模拟法,扣除系数的常见影响因素有客货列车速度比、区段均衡度、追踪间隔时分等。通过模拟法进行不同客货列车速度比下的运行图铺画,得出客货列车速度比对扣除系数的影响规律分析。实验表明:随着客货速度比的增加,扣除系数将逐渐变大,据此建议在相关双线客货混跑区段,选取合适的客货速度比,以减小对运行图通过能力的影响 相似文献

Contextual ambidexterity is of paramount importance for new product innovation and organizational success, particularly in high‐tech firms operating in a dynamic environment. Whilst it is recognized that contextual ambidexterity is grounded in organizational culture, existing research has not crystallized what kind of organizational culture enables contextual ambidexterity and consequently new product innovation. In this paper, drawing on data from 150 UK and 242 Chinese high‐tech firms, we conceptualize ambidextrous organizational culture as a higher‐order construct consisting of organizational diversity and shared vision, and examine its impacts on contextual ambidexterity and consequently on new product innovation outcomes. Using structural equation modelling, we find significant relationships between ambidextrous organizational culture, contextual ambidexterity and new product innovation outcomes; contextual ambidexterity mediates the relationship between ambidextrous organizational culture and new product innovation outcomes. Our findings also suggest that the above relationships are robust in the UK–China comparative research context, and that contextual ambidexterity and new product innovation outcomes are dependent on business unit level heterogeneity (i.e. ambidextrous organizational culture and research and development strength) rather than industry or cross‐cultural differences. 相似文献

The problem of constructing control charts for fuzzy data has been considered in literature. The proposed transformation approaches and direct fuzzy approaches have their advantages and disadvantages. The representative values charts based on transformation methods are often recommended in practical application. For representing a fuzzy set by a crisp value, the weight of importance of the members assigned with some membership levels in a fuzzy set should be considered, and the possibility theory can be employed to deal with such problem. In this article, we propose to employ the weighted possibilistic mean (WPM), weighted interval valued possibilistic mean (WIVPM) of fuzzy number as a sort of representative values for the fuzzy attribute data, and establish new fuzzy control charts with WPM and WIVPM. The performance of the charts is compared to the existing fuzzy charts with a fuzzy c-chart example via newly defined average number of inspection for variation of control state. 相似文献

This study examines the influence of resilience and transformational leadership on work engagement, and it investigates the mediating effect of positive affect. A total of 422 employees at a large IT company participated the survey. Participants completed established measures of resilience, transformational leadership, positive affect, and work engagement. The results indicate that resilience and transformational leadership are positively related to work engagement. Structural equation modeling analysis shows that positive affect partially mediates the relationships between resilience, transformational leadership, and work engagement. Theoretical contributions, practical implications, and future research directions are discussed. 相似文献

This paper is dedicated to the study of the composite quantile regression (CQR) estimations of time-varying parameter vectors for multidimensional diffusion models. Based on the local linear fitting for parameter vectors, we propose the local linear CQR estimations of the drift parameter vectors, and verify their asymptotic biases, asymptotic variances and asymptotic normality. Moreover, we discuss the asymptotic relative efficiency (ARE) of the local linear CQR estimations with respect to the local linear least-squares estimations. We obtain that the local estimations that we proposed are much more efficient than the local linear least-squares estimations. Simulation studies are constructed to show the performance of the estimations proposed. 相似文献

16世纪中叶,由于新航路的开辟,世界市场形成,白银成为世界货币。中国由于是白银贫矿国,在明代之前一直实施铜铸币和纸币政策,只是在明代中叶之后对白银货币实施了放任的政策。由于中国人多地少,劳动力十分廉价,这样以白银为计价单位所表示的商品价格极为低廉。欧洲由于人均土地资源高于中国,人均薪资也高于中国,而且白银供应极为充沛,在一般日用品价格上,远远高于中国。因而,在一般商品价格竞争上,总体不敌中国。当时美洲和日本盛产白银,是世界白银的价格洼地,欧洲又实施了较为自由的贸易政策。这样控制白银的欧洲、日本和掌握世界最低廉商品的中国,相互之间都有极为旺盛的需求,于是,世界市场很快就形成了美洲、日本白银与中国商品交换的格局。 相似文献
