Blurring the boundaries: Prosumption, circularity and online sustainable consumption through Freecycle

© The Author(s) 2015. This article explores the digital exchange and moral ordering of sustainable and ethical consumption in online Freecycle groups. Through interactive exchanges in digital (online posts) and material (consumer items) modes, Freecycling blurs three common binaries in analyses of consumption: (1) consumption/production, (2) digital/material and (3) mainstream/alternative. Drawing on Ritzer's notion of 'implosions' as well as practice theory, I show that Freecycling practices reimagine and reproduce both products and consumers, practising prosumption through mixed digital and material practices in a performative economy, and how mainstream and alternative ways of consuming are entangled in pursuit of more sustainable, ethical consumption. This challenges us to think beyond these traditional binaries and to conceptualise a more blurred, less analytically clean and more circular approach to studying consumption

Out of the comfort zone: Enhancing work-based learning about employability through student reflection on work placements

This paper examines the work-based learning about employability reported by 26 undergraduate Geography and Environmental Management students on part-time, unpaid work placements. The students' “reflective essays” emphasized their learning more in terms of emotional challenges than in terms of skills, as being pushed out of their “comfort zone” forced them to be more proactive, tackle unfamiliar activities and develop emotionally. This conceptualizes employability as more than skills and as integrative, reflective and adaptable. This also emphasizes that higher education institutions must support employability and work-based learning outside the academic zone and better integrate off-campus work-based learning with on-campus reflection

Making space for fish:The regional, network and fluid spaces of fisheries certification

In this paper, we examine the multiple spatialities of Marine Stewardship Council (MSC) certifications. The MSC uses its ecolabelling scheme to promote sustainable fisheries management; its logo may be used on the products of certified fisheries. The certification process involves the definition of a ‘fishery’. This involves the designation of boundaries around a particular location. While these boundaries suggest exclusivity for each fishery, these regional spaces are also entwined in the MSC's network, whereby they are viewed relationally. The utility of areal boundaries is also rendered problematic by the materiality of the seas: coastlines change, fish swim, water moves and ships travel. To operate its scheme successfully, the MSC has to recognise this spatial fluidity, acknowledging the rupture of boundaries and the movement of actors. We argue that attention to a multiplicity of spatialities helps direct attention to the role of non-humans in the acting out of hybrid geographies

Understanding and (dis)trusting food assurance schemes::Consumer confidence and the ‘knowledge fix’

This paper uses evidence from focus groups with consumers in England to consider how consumers understand and evaluate a range of proxies or intermediary organisations that offer assurance about food and consumer products, particularly voluntary certification schemes. This addresses the current concern in developed economies about providing information in order to reconnect consumers with food producers and to support moves towards more local, fairly traded and sustainable production. However, we show that such a ‘knowledge fix’ approach of providing information may not reconnect consumers so easily. Participants found it particularly difficult to work out what certification involved and what kinds of organisations were providing assurance. They built vernacular typologies and comparative judgements that did not necessarily identify or prioritise ‘independent’ third-party certification as the gold standard, not least because of the practical difficulties of monitoring complex supply chains, and expressed confusion and scepticism about how well food assurance schemes could work in practice. Our results therefore problematise the knowledge fix urged in the literature and emphasise instead the need to better understand how consumers make sense of assurance information in different contexts

The suite of models included three Eulerian-grid models (three implementations of one of these models), a Lagrangian atmospheric dispersion model and two moving box air parcel models. The assignments as to NOx- or VOC-sensitive and to UK- versus RoE-dominant, turned out to be highly variable and often contradictory between the individual models. However, when the assignments were filtered by model performance on each day, many of the contradictions could be eliminated. Nevertheless, no one model was found to be the 'best' model on all days, indicating that no single air quality model could currently be relied upon to inform policymakers robustly in terms of NOx- versus VOC-sensitivity and UK- versus RoE-dominance on each day. It is important to maintain a diversity in model approaches.Peer reviewedFinal Accepted Versio

Allergy and Risk of Childhood Leukaemia: Results from the UKCCS

We investigated the relationship between childhood leukaemia and preceding history of allergy. A nationwide case-control study of childhood cancers was conducted in the United Kingdom with population-based sampling of cases (n = 839) and controls (n = 1,337), matched on age, sex and region of residence. Information about clinically diagnosed allergies was obtained from primary care records. More than a third of subjects had at least one allergy diagnosed prior to leukaemia diagnosis (cases) or pseudo-diagnosis (controls). For both total acute lymphoblastic leukaemia (ALL) and common-ALL/precursor B-cell ALL (c-ALL), a history of eczema was associated with a 30% significant reduction in risk: the odds ratios (OR) and 95% confidence intervals (CI) were 0.70 (0.51-0.97) and 0.68 (0.48-0.98), respectively. Similar associations were observed for hayfever (OR = 0.47; 95% CI: 0.26-0.85 and OR = 0.62; 95% CI: 0.33-1.16 for ALL and c-ALL, respectively). No such patterns were seen either for asthma and ALL, or for any allergy and acute myeloid leukaemia. A comparative analysis of primary care records with parents recall of allergy revealed only moderate agreement with contemporaneous clinical diagnoses for both cases and controls - confirming the unreliability of parental report at interview. Our finding of a reciprocal relationship between allergy and ALL in children is compatible with the hypothesis that a dysregulated immune response is a critical determinant of childhood ALL

Dysmature superficial white matter microstructure in developmental focal epilepsy

Benign epilepsy with centrotemporal spikes is a common childhood epilepsy syndrome that predominantly affects boys, characterized by self-limited focal seizures arising from the perirolandic cortex and fine motor abnormalities. Concurrent with the age-specific presentation of this syndrome, the brain undergoes a developmentally choreographed sequence of white matter microstructural changes, including maturation of association u-fibres abutting the cortex. These short fibres mediate local cortico-cortical communication and provide an age-sensitive structural substrate that could support a focal disease process. To test this hypothesis, we evaluated the microstructural properties of superficial white matter in regions corresponding to u-fibres underlying the perirolandic seizure onset zone in children with this epilepsy syndrome compared with healthy controls. To verify the spatial specificity of these features, we characterized global superficial and deep white matter properties. We further evaluated the characteristics of the perirolandic white matter in relation to performance on a fine motor task, gender and abnormalities observed on EEG. Children with benign epilepsy with centrotemporal spikes (n = 20) and healthy controls (n = 14) underwent multimodal testing with high-resolution MRI including diffusion tensor imaging sequences, sleep EEG recordings and fine motor assessment. We compared white matter microstructural characteristics (axial, radial and mean diffusivity, and fractional anisotropy) between groups in each region. We found distinct abnormalities corresponding to the perirolandic u-fibre region, with increased axial, radial and mean diffusivity and fractional anisotropy values in children with epilepsy (P = 0.039, P = 0.035, P = 0.042 and P = 0.017, respectively). Increased fractional anisotropy in this region, consistent with decreased integrity of crossing sensorimotor u-fibres, correlated with inferior fine motor performance (P = 0.029). There were gender-specific differences in white matter microstructure in the perirolandic region; males and females with epilepsy and healthy males had higher diffusion and fractional anisotropy values than healthy females (P ≤ 0.035 for all measures), suggesting that typical patterns of white matter development disproportionately predispose boys to this developmental epilepsy syndrome. Perirolandic white matter microstructure showed no relationship to epilepsy duration, duration seizure free, or epileptiform burden. There were no group differences in diffusivity or fractional anisotropy in superficial white matter outside of the perirolandic region. Children with epilepsy had increased radial diffusivity (P = 0.022) and decreased fractional anisotropy (P = 0.027) in deep white matter, consistent with a global delay in white matter maturation. These data provide evidence that atypical maturation of white matter microstructure is a basic feature in benign epilepsy with centrotemporal spikes and may contribute to the epilepsy, male predisposition and clinical comorbidities observed in this disorder.K23 NS092923 - NINDS NIH HHSPublished versio
