Social Networks of Researchers in Business To Business Marketing: A Case Study of the IMP Group 1984-1999

Science is a social process that functions through social networks of researchers that form invisible colleges. Analysis of these social networks provides a means for examining the structure of relations among researchers. The Industrial Marketing and Purchasing (IMP) group, "an informal international group of scholars concerned with developing concepts and knowledge in the field of business-to-business marketing and purchasing," is used as a case study of a network of researchers because it has been responsible for considerable research over the last decades in the area of business-to-business marketing, yet its structure remains hidden because of its informal network characteristics. The results of a social network analysis of the IMP group is described based on the pattern of co-authorship at annual IMP conferences. The results reveal a power law distribution of paper co-authorship and a small world network that conforms to the results of studies of other types of social networks. A core network of 57 researchers is identified and its network properties are described, including how it has evolved over time. The study provides the basis for further studies of the social networks of marketing and business researchers.informal networks, business-to-business marketing

Flux tubes and string breaking in three dimensional SU(2) Yang-Mills theory

We consider the three dimensional SU(2) Yang-Mills theory with adjoint static color sources, studying by lattice simulations how the shape of the flux tube changes when increasing the distance between them. The disappearance of the flux tube at string breaking is quite abrupt, but precursors of this phenomenon are present already when the separation between the sources is smaller than its critical value, a fact that influences also some details of the static potential

The unreasonable effectiveness of effective string theory: the case of the 3d SU(2) Higgs model

We study string breaking in the three dimensional SU(2) Higgs model, using values of the gauge coupling for which the confinement-like and Higgs-like regions of the phase diagram are separated just by a smooth crossover. We show that even in the presence of string breaking, the confining part of the interquark potential is well described by the Effective String Theory and that also the fine details of the effective string, like the higher order terms of the Nambu-Goto action or the boundary correction, can be precisely extracted from the fits and agree with the effective string predictions. We comment on the implications of these results for QCD simulations with dynamical quarks.Comment: 9 pages, 6 eps figure

The performative power of frictions and new possibilities: studying power, performativity and process with Follett’s pragmatism

This article seeks to open up new possibilities for process organization studies to reimagine power and performativity by exploring the potential of Mary Parker Follett’s pragmatism as process philosophy. I revisit her body of work to show how she translated her process ontology into theoretical resources and practical insights that allow for new ways of understanding power and performativity together and explore them as mutually constituting processes of organizing. In particular, I mobilize Follett’s view of conflicts as emerging differences in the world and frictions as constructive conflicts with the potential to generate something new in order to introduce and conceptualize ‘performative power’, that is, the power emerging from relating and integrating differences in organizational situations that are experienced as frictions by people involved. Drawing on my ethnographic study of an entrepreneurship accelerator – a training programme for innovators and start-up projects – I discuss and illustrate empirically how performative power is generated from frictions that arise in ordinary lived experiences. This conceptualization of performative power is an attempt to develop a processual and performative understanding of power, and a useful lens to conduct process research. Making a connection between performative power and the experience of frictions provides a new way to see, talk and study processually power in contemporary organizations

A new solution suggesting the need for a new equation

When Victoria Hale first came up with the notion of starting the Institute for OneWorld Health (iOWH), some cautioned that the idea of a non-profit pharmaceutical company developing drugs to treat neglected diseases was a proven loser. The more direct among them might also have inquired why a successful scientist, trained in being analytic, consistent and logical, would undertake such an evidently hopeless project. Yet a few years later, iOWH has not only achieved its first drug approval (i.e. Paramomycin for the treatment of leishmaniasis or ‘black fever’, approved for use in India), it has also seen that same drug included in WHO’s Essential Medicines list, and has research results in the New England Journal of Medicine. This turnaround raises a question: Did skeptics fail to grasp Hale’s clever insights, misjudge the depth of her commitment, or underestimate the extent of her potential good fortune? Put more simply, is Hale’s a story of smarts, guts, and luck

Use of delivery drones for humanitarian operations: analysis of adoption barriers among logistics service providers from the technology acceptance model perspective

Delivery drones are yet to be adopted as a systematic delivery system for humanitarian operations but have the potential to substantially increase the efficiency and effectiveness of future delivery options. Thus, we analyse the impact of factors affecting the adoption of delivery drones by logistics service providers for humanitarian operations. A conceptual model of potential barriers to adoption and development is created using the Technology Acceptance Model theory involving security, perceived usefulness, perceived ease of use and attitude as factors that affect the intention to use. We validate the model using empirical data collected from 103 respondents by the 10 leading logistics firms located in China between May and August 2016. through a survey to examine factors currently affecting the intention/non-intention to adopt delivery drones. The results show that ease of use and addressing key security considerations about the drone, the delivery package and the recipient are crucial for adopting the technology as a specialized delivery option for logistics service providers. This is the first study of its kind and contributes to understanding the operational, supply chain and behavioural factors in the adoption of drones by logistics services providers for humanitarian operations
