Collaborative procurement is increasingly on the policy agenda in many countries, yet problems with collaboration occur. Th is article adopts a relational theory perspective to explore the enablers of and barriers to collaboration in purchasing, helping identify success factors. Th e authors adopted a mixed qualitative/quantitative methodology and interviewed 51 senior staff ers in the United K...

Local search is the most basic strategy in optimization settings when no specific problem knowledge employed. While this finds good solutions for certain problems, it generally suffers from getting stuck local optima. This stagnation can be avoided if modified. Depending on landscape, different modifications vary their success. We discuss several features of landscapes and give analyses as exam...

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and g...

We study the dynamics of the totally asymmetric exclusion process with open boundaries by phenomenological theories complemented by extensive Monte Carlo simulations. Upon combining domain wall theory with a kinetic approach known as Boltzmann-Langevin theory we are able to give a complete qualitative picture of the dynamics in the low- and high-density regimes and at the corresponding phase bo...
