Intimate Ecologies: An exploration of the languages of contemporary exhibitions and making in museums and related cultural spaces in the UK

Intimate Ecologies considers the practice of exhibition-making over the past decade in formal museum and gallery spaces and its relationship to creating a concept of craft in contemporary Britain. Different forms of expression found in traditions of still life painting, film and moving image, poetic text and performance are examined to highlight the complex layers of language at play in exhibitions and within a concept of craft. The thesis presents arguments for understanding the value of embodied material knowledge to aesthetic experience in exhibitions, across a spectrum of human expression. These are supported by reference to exhibition case studies, critical and theoretical works from fields including social anthropology, architecture, art and design history and literary criticism and a range of individual, original works of art. Intimate Ecologies concludes that the museum exhibition, as a creative medium for understanding objects, becomes enriched by close study of material practice, and embodied knowledge that draws on a concept of craft. In turn a concept of craft is refreshed by the makers’ participation in shifting patterns of exhibition-making in cultural spaces that allow the layers of language embedded in complex objects to be experienced from different perspectives. Both art-making and the experience of objects are intimate, and infinitely varied: a vibrant ecology of exhibition-making gives space to this diversity.

Development and Progress as Historical Phenomena in Tanzania: “Maendeleo? We Had That in the Past”

Academic discussions of development continue to grow, yet critical engagements with communities affected by development interventions remain limited. Drawing from life history interviews conducted in southern Tanzania, this article details the varied experiences of development interventions among older people and how these affect broader understandings of progress. Many juxtapose their negative views of ujamaa villagization with more positive recollections of previous interventions (especially the Groundnut Scheme), which are infused with what is described here as “development nostalgia.” Perceptions of the past clearly inform the social, political, and economic aspirations forwarded today, with the richness of the constructed narratives adding further nuance to existing depictions of Tanzanian historiography.

Insights into molecular and cellular events involved in normal and pathological vertebral development and fusion using zebrafish as model organism

The vertebral column and its units, the vertebrae, are fundamental features, characteristic of all vertebrates. Developmental segregation of the vertebral bodies as articulated units is an intrinsic requirement to guarantee the proper function of the spine. Whenever these units become fused either during development or postsegmentation, movement is affected in a more or less severe manner, depending on the number of vertebrae affected. Nevertheless, fusion may occur as part of regular development and as a physiological requirement, like in the tetrapod sacrum or in fish posterior vertebrae forming the urostyle. In order to meet the main objective of this PhD project, which aimed to better understand the molecular and cellular events underlying vertebral fusion under physiological and pathological conditions, a detailed characterization of the vertebral fusion occurring in zebrafish caudal fin region was conducted. This showed that fusion in the caudal fin region comprised 5 vertebral bodies, from which, only fusion between [PU1++U1] and ural2 [U2+] was still traceable during development. This involved bone deposition around the notochord sheath while fusion within the remaining vertebral bodies occur at the level of the notochord sheath, as during the early establishment of the vertebral bodies. A comparison approach between the caudal fin vertebrae and the remaining vertebral column showed conserved features such as the presence of mineralization related proteins as Osteocalcin were identified throughout the vertebral column, independently on the mineralization patterns. This unexpected presence of Osteocalcin in notochord sheath, here identified as Oc1, suggested that this gene, opposing to Oc2, generally associated with bone formation and mature osteoblast activity, is potentially associated with early mineralization events including chordacentrum formation. Nevertheless, major differences between caudal fin region and anterior vertebral bodies considering arch histology and mineralization patterns, led us to use RA as an inductive factor for vertebral fusion, allowing a direct comparison of equivalent structures under normal and fusion events. This fusion phenotype was associated with notochord sheath ectopic mineralization instead of ectopic perichordal bone formation related with increased osteoblast activity, as suggested in previous reports. Additionally, alterations in ECM content, cell adhesion and blood coagulation were discussed as potentially related with the fusion phenotype. Finally, Matrix gla protein, upregulated upon RA treatment and shown to be associated with chordacentrum mineralization sites in regular development, was further described considering its potential function in vertebral formation and pathological fusion. Therefore with this work we propose zebrafish caudal fin vertebral fusion as a potential model to study both congenital and postsegmentation fusion and we present candidate factors and genes that may be further explored in order to clarify whether we can prevent vertebral fusion.

Development and implementation of a new service delivery model for children with disabilities : implications for DCD

There is a general consensus that new service delivery models are needed for children with developmental coordination disorder (DCD). Emerging principles to guide service delivery include the use of graduated levels of intensity and evidence-based services that focus on function and participation. Interdisciplinary, community-based service delivery models based on best practice principles are needed. In this case report, we propose the Apollo model as an example of an innovative service delivery model for children with DCD. We describe the context that led to the creation of a program for children with DCD, describe the service delivery model and services, and share lessons learned through implementation. The Apollo model has 5 components: first contact, service delivery coordination, community-, group- and individual-interventions. This model guided the development of a streamlined set of services offered to children with DCD, including early-intake to share educational information with families, community interventions, inter-disciplinary and occupational therapy groups and individual interventions. Following implementation of the Apollo model, waiting times decreased and numbers of children receiving services increased, without compromising service quality. Lessons learned are shared to facilitate development of other practice models to support children with DCD.

Lyophilisation of influenza, rabies and Marburg lentiviral pseudotype viruses for the development and distribution of a neutralisation-assay based diagnostic kit

Pseudotype viruses (PVs) are chimeric, replication-deficient virions that mimic wild-type virus entry mechanisms and can be safely employed in neutralisation assays, bypassing the need for high biosafety requirements and performing comparably to established serological assays. However, PV supernatant necessitates -80°C long-term storage and cold-chain maintenance during transport, which limits the scope of dissemination and application throughout resource-limited laboratories. We therefore investigated the effects of lyophilisation on influenza, rabies and Marburg PV stability, with a view to developing a pseudotype virus neutralisation assay (PVNA) based kit suitable for affordable global distribution. Infectivity of each PV was calculated after lyophilisation and immediate reconstitution, as well as subsequent to incubation of freeze-dried pellets at varying temperatures, humidities and timepoints. Integrity of glycoprotein structure following treatment was also assessed by employing lyophilised PVs in downstream PVNAs. In the presence of 0.5M sucrose-PBS cryoprotectant, each freeze-dried pseudotype was stably stored for 4 weeks at up to 37°C and could be neutralised to the same potency as unlyophilised PVs when employed in PVNAs. These results confirm the viability of a freeze-dried PVNA-based kit, which could significantly facilitate low-cost serology for a wide portfolio of emerging infectious viruses.
