Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...

Research on Natural Characteristics of Helical Gear in Gearbox for Wind Turbine Generator
The three-dimensional helical gear model based on the geometric parameters is created by using software called PROE3.0. The natural characteristics of helical gear are analyzed by using the finite element method. The natural frequency of the helical gear

Supply Chain Coherence: Building Resilience for an Ever‐Changing World
ABSTRACT In this article, it is argued that a key to resilience is maintaining a coherent supply chain despite the multitude of—often unforeseeable—challenges it encounters. Because there is a dearth of literature focusing specifically on supply chain coherence, this research explores the meaning and conceptualization of coherence in related fields ...

ABSTRACT The revival of Biafran separatism in contemporary Nigeria is often explained with three leading theoretical frameworks: relative deprivation, political economy and state repression. Whereas relative deprivation and political economy perspectives posit that the resurgent separatism derives from the perception and empirical reality of ...
