The impact of external forces on cartel network dynamics: Direct research in the diamond industry

This paper describes the impact of external environmental forces on cartel networks. Using a case research approach, this report examines two leading business networks within one industry, over time. The results suggest that (a) bargaining power of intermediaries increases with the advent of new and powerful actors, (b) process activities that cartels previously controlled are being outsourced to new actors sometimes based in developing countries, (c) other actors are acquiring resources once dominated by a cartel, (d) external forces triggered by the illegal diamond trade, such as international regulatory constraints, no longer favour cartels like De Beers, and (e) over time, these and additional environment factors are forcing actors like De Beers who perform rigid process activities to become more flexible. For example, forces are moving cartels which relied previously on hand-picked intermediaries in highly controlled networks to market their products to adopt a flexible market-focused expansion of operations in retail contexts.     

From complexity to transparency: managing the interplay between theory, method and empirical phenomena in IMM case studies

Theory, method and empirical phenomena are the three cornerstones of research. In this paper we contemplate the interplay between them when case research in industrial marketing is concerned. Developments in research depend on what empirical phenomena we are able to capture, how theories are developed to understand and explain these phenomena and what methods we use and/or develop in the process. While the emphasis is often put on one of these aspects alone, this paper focuses on the links and interplay between theory, case method and empirical phenomena in the development of research in industrial marketing. Specifically, we seek to provide common ground between orthodox (deductive) and unorthodox (abductive) approaches to managing the interplay by making a pragmatic call for transparency in research procedures. In this endeavour we use the papers included in this special issue as examples of various aspects of this interplay. We conclude by suggesting that there is a gamut of approaches possible to case research in industrial marketing, each with its specific links to theory and empirical phenomena, and that this is promising for the development of research in the field, as long as it helps reduce, rather than increase, the complexity of the case studied.     

A quality function deployment approach to improve maritime supply chain resilience

Being international and involving numerous organizations as the basic nature, maritime supply chains are exposed to various natural and man-made risks. This paper aims to develop an original quality function deployment approach to enhance maritime supply chain resilience, taking both customer requirements and maritime risks into consideration. The empirical analysis is carried out through in-depth studies of three major shipping lines and their respective major shippers. The top three resilience measures are contingency plan, monitoring and maintenance, and supply chain relationship management. The study also unveils the relatively low visibility and integration in maritime supply chains.

快速校正天波雷达电离层相位污染的改进方法

时变的电离层会对天波超视距雷达(OTHR)回波信号相位进行调制,产生相位污染,导致回波谱展宽。最大似然估计(MLE)法具有比相位梯度法更佳的污染校正效果,但计算量非常大。通过引入投影近似子空间跟踪法,提出了一种改进的MLE方法。改进方法采用递归手段估计最大特征值对应的特征向量,避免了特征值分解过程,能够显著降低计算量,污染校正效果与MLE法相当。理论分析与仿真对比表明改进方法普适性强,计算量只有MLE法的万分之一,更适合工程实现。     

中小机场运营与补贴之间的互动探究

基于2013—2021年国内73个中小机场的面板数据,运用DEA(数据包络分析)模型计算机场运营效率,并对面板数据进行回归分析。研究发现,2013—2019年国内中小机场的运营效率呈上升趋势,但2020—2021年受新冠肺炎疫情影响,运营效率显著下降。进一步研究表明,机场补贴对中小机场的运营效率具有显著正向促进作用。虽然机场效率不能直接影响补贴,但机场业务量对补贴有正向显著影响。因此,提出加强对中小机场的政策支持、注重提高机场业务量、建立应对突发事件的机制等措施,以促进中小机场的可持续发展。
