Community perceptions of carbon farming: A case study of the semi-arid Mulga Lands in Queensland, Australia

International efforts to combat climate change are reflected in diverse national and subnational policies, the effects of which can stimulate fundamental changes in land use at the regional scale. Since 2012, the Australian Government has provided incentives for landholders to implement “carbon farming” through methods that either sequester or avoid the release of carbon emissions in vegetation and soils. While the factors leading to individual landholder adoption of carbon farming is widely researched, there is comparatively limited analysis of broader community perceptions and potential impacts of its resulting changes in land use and management. This research uses semi-structured interviews and qualitative analysis to explore community perceptions of carbon farming in the vast and remote Mulga Lands of Queensland, Australia, a region that supports nearly 200 carbon projects across 7 million hectares. We found that individual landholders were motivated to adopt carbon farming primarily for the economic benefits, despite sharing concerns with the broader community over potential environmental and social impacts. Long-standing local attitudes, values and beliefs around perceived desirable natural landscapes, and their role in maintaining agricultural production, underpin a view that non-active land management and absentee land ownership – considered by some in the community to be a consequence of carbon farming – would contribute to ongoing rural decline. Our findings show that the scale and pace of land use changes facilitated by carbon farming have led to a community impact in the Mulga Lands. Such impacts must be explicitly considered in future research, policy and planning to ensure land use transitions stimulated by carbon farming policy are effectively and fairly managed

Engaging political histories of urban uprisings with young people: The Liverpool riots, 1981 and 2011

Based on a participatory research project which involved academics and young people at KCC Live, a community radio station in Merseyside, exploring the 1981 and 2011 riots in Liverpool, UK, this paper argues that co-produced research involving young people and radio provides an under-utilised avenue for research on historical and political geographies. Working together for a year in 2012–13, the academic and non-academic participants produced a radio documentary exploring how and why the 1981 riots in Liverpool occurred, and what we could learn from those historical events to help understand the more recent 2011 riots. Young people’s capacities to engage with past events that took place before they were born, in order to reflect on and understand the political present, are seldom explored in research. The research that this paper is based on therefore provides an original and significant contribution to debates on conducting research with young people, in particular developing approaches to thinking through how young people engage with, and make sense of, politics and political activity, especially disruptive or insurgent activities like riots/urban uprisings. As a result, the paper makes an important contribution to work being done on the political capacities of young people; collective histories and memories in young people’s understandings of politics, place, and space; and knowledges of urban uprisings. We argue that bringing children’s/youth geographies into dialogue with political and historical geographies such as those discussed here is a useful avenue for future research. © The Author(s) 2020

Teachers’ Adoption of Embodied Learning Digital Games with an Inclusive Education Approach: Lessons Learnt from the INTELed Project in Spain

Producción CientíficaEmbodied learning digital games have been used with success in the past to support students with special education needs, but their application by teachers in mainstream classes with an inclusive approach is still a challenge. This paper presents the results of a set of pilots in which a suite of embodied digital games was applied into pre-school and primary school classrooms. The findings of the studies provide insights into the conditions that facilitated and/or impeded the adoption of the technology by the participant teachers. These results are then elaborated to define a first set of strategies that could be used by third-party teachers to fulfill the same objectives, and to identify concrete design challenges for the application of embodied digital games in classrooms.Ministerio de Ciencia, Innovación y Universidades (Project TIN2017-85179-C3-2-R)Junta de Castilla y León (Project VA257P18 (CASSUALearn

Extending the applicability of the dose addition model to the assessment of chemical mixtures of partial agonists by using a novel toxic unit extrapolation method

This article has been made available through the Brunel Open Access Publishing Fund.Dose addition, a commonly used concept in toxicology for the prediction of chemical mixture effects, cannot readily be applied to mixtures of partial agonists with differing maximal effects. Due to its mathematical features, effect levels that exceed the maximal effect of the least efficacious compound present in the mixture, cannot be calculated. This poses problems when dealing with mixtures likely to be encountered in realistic assessment situations where chemicals often show differing maximal effects. To overcome this limitation, we developed a pragmatic solution that extrapolates the toxic units of partial agonists to effect levels beyond their maximal efficacy. We extrapolated different additivity expectations that reflect theoretically possible extremes and validated this approach with a mixture of 21 estrogenic chemicals in the E-Screen. This assay measures the proliferation of human epithelial breast cancers. We found that the dose-response curves of the estrogenic agents exhibited widely varying shapes, slopes and maximal effects, which made it necessary to extrapolate mixture responses above 14% proliferation. Our toxic unit extrapolation approach predicted all mixture responses accurately. It extends the applicability of dose addition to combinations of agents with differing saturating effects and removes an important bottleneck that has severely hampered the use of dose addition in the past. © 2014 Scholze et al

Structural crossover in a model fluid exhibiting two length scales: repercussions for quasicrystal formation

We investigate the liquid state structure of the two-dimensional model introduced by Barkan et al. [Phys. Rev. Lett. 113, 098304 (2014)], which exhibits quasicrystalline and other unusual solid phases, focusing on the radial distribution function g(r) and its asymptotic decay r→∞. For this particular model system, we find that as the density is increased there is a structural crossover from damped oscillatory asymptotic decay with one wavelength to damped oscillatory asymptotic decay with another distinct wavelength. The ratio of these wavelengths is ≈1.932. Following the locus in the phase diagram of this structural crossover leads directly to the region where quasicrystals are found. We argue that identifying and following such a crossover line in the phase diagram towards higher densities where the solid phase(s) occur is a good strategy for finding quasicrystals in a wide variety of systems. We also show how the pole analysis of the asymptotic decay of equilibrium fluid correlations is intimately connected with the nonequilibrium growth or decay of small-amplitude density fluctuations in a bulk fluid
