Towards a sustainable economy? Socio-technical transitions in the green building sector

Making the transition to a green economy is a major policy driver in the UK and other countries. Entrepreneurs are suggested as being at the forefront of this transition and as a driving force for sustainability. These “green entrepreneurs” may represent a new type of entrepreneurial behaviour combining economic, environmental and social aims. In this paper, we present empirical work conducted with green entrepreneurs in the UK green building sector. Buildings have significant impacts on the environment, both in terms of materials and post-construction energy demands. Drawing on sustainability transitions theory, we examine the role of green entrepreneurs in affecting change and suggest that green building niches are less consensual than previously theorised. In theorising green entrepreneurs, we also point to the need to consider them within wider networks of activity rather than as lone actors and the implications this has for policy

Anisotropic imbibition on surfaces patterned with polygonal posts

We present and interpret lattice Boltzmann simulations of thick films spreading on surfaces patterned with polygonal posts. We show that the mechanism of pinning and depinning differs with the direction of advance, and demonstrate that this leads to anisotropic spreading within a certain range of material contact angles.Comment: DSFD Proceedings 201

The Lebesgue Universal Covering Problem

In 1914 Lebesgue defined a "universal covering" to be a convex subset of the plane that contains an isometric copy of any subset of diameter 1. His challenge of finding a universal covering with the least possible area has been addressed by various mathematicians: Pal, Sprague and Hansen have each created a smaller universal covering by removing regions from those known before. However, Hansen's last reduction was microsopic: he claimed to remove an area of $6 \cdot 10^{-18}$, but we show that he actually removed an area of just $8 \cdot 10^{-21}$. In the following, with the help of Greg Egan, we find a new, smaller universal covering with area less than $0.8441153$. This reduces the area of the previous best universal covering by a whopping $2.2 \cdot 10^{-5}$.Comment: 11 pages, 5 jpeg figures, numerical errors correcte

Institutionalizing alternative economic spaces? An interpretivist perspective on diverse economies

This article offers an approach that helps geographers and others to carefully and critically reexamine prospects for diverse economies. We propose an interpretative institutionalist perspective is useful for elucidating overlooked opportunities for creating alternative economic visions and practices by revealing the process of ‘meaning making’ undertaken by actors in the process of developing policy responses to various dilemmas. We explore this notion in the context of de-growth or post-growth. De-growth is a way of thinking about the economy in ways that are not growth oriented, or fixated on GDP, but on the redistribution of wealth and living within the Earth’s ecosystems

The Community of Workers' University: a pragmatic institution for the future?

The identity of the worker foregrounds the development of higher education rather than the other way around. It is developed in contrast to the lack of higher education innovation in the recent UK Government White Paper on Higher Education and in the educational philosophy of Tawney and the neo-pragmaticism of Rorty. The proposal is that higher learning, after capabilities have been nurtured in compulsory schooling, may be developed through communities of workers acting as agent for improvement of their communities; not in universities at all. This is a radical approach to higher education and employment and one that might bring true diversity to the higher education sector

Early-life risk factors which govern pro-allergic immunity.

Allergic diseases affect up to 40% of the global population with a substantial rise in food allergies, in particular, over the past decades. For the majority of individuals with allergy fundamental programming of a pro-allergic immune system largely occurs in early childhood where it is crucially governed by prenatal genetic and environmental factors, including their interactions. These factors include several genetic aberrations, such as filaggrin loss-of-function mutations, early exposure to respiratory syncytial virus, and various chemicals such as plasticizers, as well as the influence of the gut microbiome and numerous lifestyle circumstances. The effects of such a wide range of factors on allergic responses to an array of potential allergens is complex and the severity of these responses in a clinical setting are subsequently not easy to predict at the present time. However, some parameters which condition a pro-allergic immune response, including severe anaphylaxis, are becoming clearer. This review summarises what we currently know, and don't know, about the factors which influence developing pro-allergic immunity particularly during the early-life perinatal period
