‘Missing out’: Reflections on the positioning of ethnographic research within an evaluative framing

Contemporary approaches to evaluating ‘complex’ social and health interventions are opening up spaces for methodologies attuned to examining contextual complexities, such as ethnography. Yet the alignment of the two agendas – evaluative and ethnographic – is not necessarily comfortable in practice. I reflect on experiences of conducting ethnographic research alongside a public health evaluation of a community-based initiative in the UK, using the lens of ‘missing out’ to examine intersections between my own ethnographic concerns and those of the communities under study. I examine potential opportunities posed by the discomfort of ‘missing out’, particularly for identifying the processes and spaces of inclusion and exclusion that contributed both to my ethnographic experiences and to the realities of the communities engaging with the initiative. This reveals productive possibilities for a focus on ‘missing out’ as a form of relating for evaluations of the impacts of such initiatives on health and social inequalities

Small-sized magnesium cylinders influence subchondral bone quality in osteoarthritic rabbits an – in vivo pilot study

No optimal therapy exists to stop or cure chondral degeneration in osteoarthritis (OA). While the pathogenesis is unclear, there is consensus on the etiological involvement of both articular cartilage and subchondral bone. Compared to original bone, the substance of sclerotic bone is mechanically less solid. The osteoproliferative effect of Mg has been shown repeatedly during development of Mg-based osteosynthesis implants. The aim of the present study was to examine the influence of implanted high-purity Mg cylinders on subchondral bone quality in a rabbit OA model. 10 New Zealand White rabbits received into the knee either 20 empty drill holes or 20 drill holes, which were additionally filled with one Mg cylinder each. Follow-up was at 8 weeks. Micro-computed tomography (µCT) was performed. After euthanasia, cartilage condition was determined, bone samples were collected and processed for histological evaluation and elemental imaging by micro-Xray fluorescence spectrometry (µXRF). Articular cartilage collected post-mortem showed different stages of lesions, from mild alterations up to exposed subchondral bone, which tended to be slightly lower in animals with implanted Mg cylinders. µCT showed significantly increased bone volume in the Mg group. Also, histological evaluation revealed distinct differences. While right, operated limbs did not show any significant difference, left, non-operated controls showed significantly less changes in articular cartilage in the Mg group. A distinct influence of implanted cylinders of pure Mg on subchondral bone of osteoarthritic rabbits was shown. Subsequent evaluations, including other time points and alternative alloys, will show if this could alter OA progression

Functional detection of MDR1/P170 and MRP/P190-mediated multidrug resistance in tumour cells by flow cytometry.

Multidrug resistance (MDR) in tumour cells is often caused by the overexpression of the plasma membrane drug transporter P-glycoprotein (P-gp) or the recently discovered multidrug resistance-associated protein (MRP). In this study we investigated the specificity and sensitivity of the fluorescent probes rhodamine 123 (R123), daunorubicin (DNR) and calcein acetoxymethyl ester (calcein-AM) in order to detect the function of the drug transporters P-gp and MRP, using flow cytometry. The effects of modulators on the accumulation and retention of these probes were compared in several pairs of sensitive and P-gp- as well as MRP-overexpressing cell lines. R123, in combination with the modulator PSC833, provided the most sensitive test for detecting P-gp-mediated resistance. Moreover, in a 60 min drug accumulation assay R123 can be regarded as a P-gp-specific probe, since R123 is not very efficiently effluxed by MRP. In contrast to R123, a 60 min DNR or calcein-AM accumulation test could be used to detect MRP-mediated resistance. The MRP-specific modulator genistein could be used in combination with DNR, but not with calcein-AM. Vincristine (VCR) can be used to increase the cellular uptake of calcein-AM in MDR cells, but is not specific for MRP. Thus, although the combination of DNR with genistein appeared to be as sensitive as the combination of calcein-AM with VCR, the former may be used to probe specific MRP activity whereas the latter provides a combined (P-gp + MRP) functional MDR parameter. With these functional assays the role and relative importance of P-gp and MRP can be studied in, for example, haematological malignancies

Postcolonial Transplants: Cinema, Diaspora and the Body Politic

This essay examines depictions of migrant workers in French and British postcolonial cinema as transplanted interlopers, 'exotic' or transgendered bodies that are perceived as a threat to the integrity of the body politic

Bereavement and the role of religious and cultural factors.

yesThe aim of this article is to give an overview of some of the key dimensions of variation in cultural and religious rituals during the immediate period after a death and in the longer term, in order to inform service delivery in multi-cultural societies. For each area we give examples of different customs, and consider their functions and possible impact. Dimensions considered in the immediate period after bereavement are: The time and space given to formal rituals, expression of feelings, assertion of status and disposal of the body. In the longer term, we look at variations in remembering the deceased and in continuing bonds. Throughout we consider the interplay between individual responses and the person¿s cultural and religious context. Our objective is to provide an accessible introduction for practitioners new to working with bereavement and provide a succinct reference point for more experienced bereavement workers.Full text made available 1st May 2014 at the end of the publisher's embargo period

Revisiting Ruddick: Feminism, pacifism and non-violence

This article explores feminist contentions over pacifism and non-violence in the contextof the Greenham Common Peace Camp in the 1980s and later developments offeminist Just War Theory. We argue that Sara Ruddick’s work puts feminist pacifism, its radical feminist critics and feminist just war theory equally into question. Although Ruddick does not resolve the contestations within feminism over peace, violence and the questions of war, she offers a productive way of holding the tension between them. In our judgment, her work is helpful not only for developing a feminist political response to the threats and temptations of violent strategies but also for thinking through the question of the relation between violence and politics as such
