Cutting edge: Science hackathons for developing interdisciplinary research and collaborations

Science hackathons can help academics, particularly those in the early stage of their careers, to build collaborations and write research proposals.This work was funded by the UK Engineering and Physical Sciences Research Council under grant numbers EP/I017909/1 (www.2020science.net), and by the Department of Mathematics at Imperial College London under the EPSRC Mathematics Platform grant EP/I019111/1

Social Entrepreneurs by Chance: How environmentalists provide a favorable context for social entrepreneurial action.

How, why, and under what conditions can social movements contribute to the development of social entrepreneurial process developed by embedded actors? Social entrepreneurship scholars are increasingly adopting social movement theories to explain how individual entrepreneurs develop their social ventures. Despite the synergies achieved when combining social movement with social entrepreneurship literature, social entrepreneurial outcomes are still mostly explained by the efforts of atomistic actors. In this paper we offer an embedded perspective on social entrepreneurship and social movement, which enables us to examine their complementary features in a sustainable development project in a Dutch region. While contentious activity did not produce the desired effect in our case, we found that the various stages of social entrepreneurship processes (opportunity identification, evaluation, formalization, and exploitation) through which embedded actors develop their ventures were especially enhanced by joint knowledge creation between movements and embedded actors, the construction of producer identities, and direct business support. This study contributes to the social movement literature by showing how movements can bring about change by providing embedded actors with producers’ identities and hands-on support. The literature on social entrepreneurship is also complemented, as we show how motives and behaviors to engage in social entrepreneurship are shaped by social movements, in combination with changes in the degree of embeddedness

Analyzing and Modeling the Performance of the HemeLB Lattice-Boltzmann Simulation Environment

We investigate the performance of the HemeLB lattice-Boltzmann simulator for cerebrovascular blood flow, aimed at providing timely and clinically relevant assistance to neurosurgeons. HemeLB is optimised for sparse geometries, supports interactive use, and scales well to 32,768 cores for problems with ~81 million lattice sites. We obtain a maximum performance of 29.5 billion site updates per second, with only an 11% slowdown for highly sparse problems (5% fluid fraction). We present steering and visualisation performance measurements and provide a model which allows users to predict the performance, thereby determining how to run simulations with maximum accuracy within time constraints.Comment: Accepted by the Journal of Computational Science. 33 pages, 16 figures, 7 table

The evolution of business incubators: comparing demand and supply of business incubation services across different incubator generations

Business incubators (BIs) have been established around the world to stimulate new business creation. Whilst it is accepted that incubation models have evolved, little is known about whether existing incubators have adjusted their value proposition to incorporate recent incubation paradigms or have simply remained operating as originally founded. We present data collected within seven BIs and their tenants regarding service provision and selection criteria. Our findings show that whilst BIs of all generations offer similar support services, tenants in older generation BIs make less use of the BI's service portfolio. We suggest this is a consequence of slack selection criteria and the absence of clearly defined exit policies. These results imply that older generation BIs should update their service portfolio while simultaneously imposing stricter selection criteria and introducing exit policies. Finally, we discuss the wider implications this raises for BIs' managers, prospective tenants and policy makers.\ud \u
