In this article we use the Urban Political Ecology approach to show that by analysing governance networks we can better understand the production of certain socio-environmental transformations that negatively affect some social groups while benefiting others. Drawing upon two case studies in the UK, the article explores the dialectical relationships between different modes of urban governance on one hand and the socio-environmental transformations fulfilled in each case study on the other hand. The article concludes that although urban regeneration policies are always constrained by the neoliberal established framework of power relations, policy outputs and outcomes could be very different from one place to another, shaping uneven socio-environmental constructions. Finally, we make some recommendations in order to stimulate the production of more sustainable communities in the future.

INTRODUCTION Evolution of behavioral responses is often dependent on the existence of modified structures that enable the development of the behavioral suite(Kay 1978;Lundrigan 1996;Alfaro et al.2004;Goyens et al.2015;Higham et al.2015;sharp et al.2018;schendel et al.2019).Occasionally,structural modifications are so important that a direct link between morphology and behavior can be inferred(Fleagle 1977;Rodman 1979;Losos 1990a;Higham et al.2015).

The energy use in buildings has to be decreased to reach the targets and regulations in the European Union. One way of reducing the energy demand is to use vacuum insulation panels （VIP） in the buitding envelope. To make sure the declared thermal properties of the VlP are valid for the mounted panels, in situ measurements are needed. The transient plane source （TPs） method allows fast measurement of the thermal properties of a variety of materials. However, the large anisotropy of the VIP makes it hard to interpret the temperature increase in the TPs sensor. This paper presents a compar.son between an analytical solution, numerical simulations and TPs measurements of polystyrene and polystyrene with aluminum film. Polystyrene and aluminum were used instead of VIP to increase the number of setups. The numerical simulation model was validated by comparing the simulated temperature increase with an analytical solution for the polystyrene sample. The simulated temperature increase in the polystyrene sample after 40 s was 7.8% higher than the TPs measurements. For the case with polystyrene with aluminum film, the deviation was 5.7%. Losses in the wires of the TPs sensor, uncertainties regarding the material parameters and surface resistances could explain the deviations.

Canada’s boreal forest represents an important contributor of the world’s wood supply industry. However,maintaining or increasing productivity of the boreal forest may be challenging in areas dominated by forested peatlands. Moreover, sustainable management of these forests must also consider other important aspects of the forest ecosystem such as biodiversity and carbon sequestration. To address these concerns, ecosystem-based management has been implemented in some Canadian jurisdictions, such as in regions where a large portion of the boreal forest is dominated by forested peatlands. The objectives of this paper are(1) to summarize our current understanding of how natural disturbances influence stand dynamics and biodiversity in forested peatlands, and(2) to review the main differences between natural and managed forest stands with respect to soil properties, stand productivity, understory plant communities. We also discuss how even-age management regime succeeds or fails to preserve old forests and how this loss affects both forest structure and habitat diversity at the landscape *** conclude by showing how, in boreal forested peatlands, forest management could contribute to carbon sequestration and mitigate projected climate change.
