‘We view that as contraceptive failure’: Containing the ‘multiplicity’ of contraception and abortion within Scottish reproductive healthcare

AbstractWithin contemporary Scottish policy guidance, abortion is routinely configured as evidence of a resolvable problem with the healthcare provision of contraception. This article draws on 42 semi-structured interviews with Scottish health professionals conducted during 2007–2008, in order to explore how, and in what form, realities of contraception/abortion are sustained within abortion practice. In addition to providing empirical insights concerning this sociologically neglected aspect of reproductive healthcare, it demonstrates how a novel conceptual approach could be used to develop existing social scientific analyses of the provision of techniques of fertility prevention. Science and Technology Studies (STS) has highlighted the importance of studying the complex socio-material practices through which realities are enacted (or ‘performed’). Mobilising this insight, my analysis illustrates the complex socio-material work required to enact abortion as evidence of a ‘problem’ with contraception that is resolvable within the healthcare consultation. This work, I argue, renders visible the ontologically ‘multiple’ (Mol, 2002) nature of contraception/abortion, with important implications for both social science and policy approaches to these techniques of fertility prevention

Concrete and non-concrete: exploring the contemporary authenticity of historic replicas through an ethnographic study of the St John's Cross replica, Iona

What do we actually know about how replicas of historical objects and monuments 'work' in heritage contexts, in particular their cultural significance and intangible values? In this article we examine this question drawing on ethnographic research surrounding the 1970 concrete replica of the eighth-century St John’s Cross on Iona, Scotland. Challenging traditional precepts that seek authenticity in qualities intrinsic to original historic objects, we show how replicas can acquire authenticity and 'pastness', linked to materiality, craft practices, creativity, and place. We argue that their authenticity is founded on the networks of relationships between people, places and things that they come to embody, as well as their dynamic material qualities. The cultural biographies of replicas, and the 'felt relationships' associated with them, play a key role in the generation and negotiation of authenticity, while at the same time informing the authenticity and value of their historic counterparts through the 'composite biographies' produced. As things in their own right, replicas can 'work' for us if we let them, particularly if clues are available about their makers’ passion, creativity and craft

The untold heritage value and significance of replicas

This article focuses on the fraught questions surrounding replicas and their use in heritage contexts, drawing on the first in-depth qualitative study of a historic replica, the 1970 concrete St John's Cross, Iona. We examine how replicas 'work' and unravel the part that social relations, place and materiality play in the production and negotiation of authenticity. The research shows that replicas are important objects in their own right, acquiring value, authenticity and aura. The 'life' of a replica generates networks of relationships between people, places and things, including the original historic object, becoming part of its 'composite' biography. While the underlying human stories of creativity, skill and craftsmanship are rendered invisible when replicas are treated as mere surrogates, we argue that these 'life-stories' should be incorporated into future conservation, management and interpretation. The article spells out practical advice and guidance for heritage professionals who find themselves dealing with replicas

3D heritage visualisation and the negotiation of authenticity: the ACCORD project

This article examines the question of authenticity in relation to 3D visualisation of historic objects and monuments. Much of the literature locates their authenticity in the accuracy of the data and/or the realism of the resulting models. Yet critics argue that 3D visualisations undermine the experience of authenticity, disrupting people’s access to the materiality, biography and aura of their historic counterparts. The ACCORD project takes questions of authenticity and 3D visualisation into a new arena – that of community heritage practice – and uses rapid ethnographic methods to examine whether and how such visualisations acquire authenticity. The results demonstrate that subtle forms of migration and borrowing occur between the original and the digital, creating new forms of authenticity associated with the digital object. Likewise, the creation of digital models mediates the authenticity and status of their original counterparts through the networks of relations in which they are embedded. The current pre-occupation with the binary question of whether 3D digital models are authentic or not obscures the wider work that such objects do in respect to the cultural politics of ownership, attachment, place-making and regeneration. The article both advances theoretical debates and has important implications for heritage visualisation practice

3D visualisation, communities and the production of significance

In this paper, we discuss how community co-production of heritage records facilitates the production and negotiation of new forms of value and significance. We draw on case studies from the ACCORD project, which used 3D digital technologies for community engagement through co-creation, to explore how a site’s significance can be affected and challenged through community recording. Whilst multiple modes of recording operate in this way, digital 3D recording, long held as the sole domain of the technical expert, is often deployed by heritage professionals as a means of enhancing authorised historic and scientific values through the sophisticated and precise recording of a site’s physical structure. Here we argue that these recording techniques can also offer a means of exploring and challenging existing authorised regimes of significance and insignificance, giving voice to alternative and richer perspectives through the recording process itself, as much as through the resultant record. This challenges orthodox thinking about both the primary purpose and effects of digital recording and opens up new directions for their use in heritage practice

Expertise and Scottish abortion practice: understanding healthcare professionals’ accounts

Current UK abortion law has been subjected to extensive feminist critique because of the relationships that it constructs between healthcare professionals (HCPs) and women with unwanted pregnancies. The law allows HCPs to opt out of abortion provision on the grounds of conscience, implying that it is not something which they have an automatic duty to provide to their patients. It also gives doctors the authority to decide whether an abortion can legally take place, thus suggesting that women’s reproductive decisions should be regulated by medical ‘experts’. However, little is known about how HCPs who are involved in twenty-first century UK abortion provision define their relationships with their patients in practice. My thesis makes an important empirical contribution by responding to this gap in the literature and exploring the subjectivities which these HCPs construct for themselves and their pregnant patients. I address this issue by analysing Scottish HCPs’ interview accounts of their involvement in (or conscientious objection to) abortion provision, using conceptual tools provided by Science and Technology Studies (STS) and feminist theory. I begin by utilising HCPs’ discussions of the practice of ‘conscientious objection’ as a means of exploring how they define the boundaries of their professional responsibilities for abortion provision. I then move on to address HCPs’ accounts of their interactions with women requesting abortion, and analyse how they define legitimate or ‘expert’ knowledge in this context. A key conclusion of the thesis is that HCPs do concede some authority to women with unwanted pregnancies; this is revealed by their reluctance to suggest that they have the right to prevent individual women from accessing abortion. At the same time, I argue that the legitimacy granted to pregnant women by HCPs is limited. My analysis reveals that, in constructing knowledge claims about the use of abortion, HCPs co-produce troubling definitions of femininity, socio-economic class, age and ethnicity. I develop a strong critique of this process, and highlight its potential implications for women’s experiences in the abortion clinic. However, I conclude that this situation cannot be addressed by simply attacking the practices of HCPs as individuals. Rather, it is necessary to understand and critique the limitations of the discursive context in which HCPs are working, because this context shapes the subjectivities available to pregnant women and HCPs

Establishing the Effect of Brushing and a Day’s Diet on Tooth Tissue Loss in Vitro

To develop an in vitro model to mimic the effects of meals equivalent to a day’s diet on tooth tissue loss (TTL). To identify how diet effects tooth wear and to test the efficacy of dental products designed to reduce tooth wear in a more realistic environment. A typical Friday diet was devised comprising: Breakfast then brushing, lunch, dinner then brushing. Groups of enamel samples were exposed to one meal, or all three in series, a control group was exposed to water and brushed. The daily cycle was repeated to represent two days’ consumption; TTL was quantified by non-contact profilometry. This pilot study highlighted adaptions that could be made to the model such as human enamel and saliva to further replicate natural eating habits. The sum of the TTL measured after Breakfast, lunch and dinner (bovine enamel specimens exposed to single meals) was less than that exhibited by the group of samples exposed to the series of meals but this difference was not significant (p = 0.09).In the absence and presence of brushing, TTL caused by breakfast and dinner was similar, but significantly greater than that caused by lunch (p < 0.05). While brushing increased TTL, this increase was not significant. It is possible to model a daily diet in vitro, and the data obtained confirms that the combination of food and drink affects the degree of TTL. This supports the further development of an in vitro model that includes alternative foodstuffs. This would aid understanding of the effects different diets have on TTL and could test new products designed to prevent TTL

The flow of a foam in a two-dimensional porous medium

International audienceFoams have been used for decades as displacing fluids for enhanced oil recovery and aquifer remediation, and more recently, for remediation of the vadose zone, in which case foams carry chemical amendments. Foams are better injection fluids than aqueous solutions due to their low sensitivity to gravity and because they are less sensitive to permeability heterogeneities, thus allowing a more uniform sweep. The latter aspect results from their peculiar rheology, whose understanding motivates the present study. We investigate foam flow through a two-dimensional porous medium consisting of circular obstacles positioned randomly in a horizontal transparent Hele-Shaw cell. The local foam structure is recorded in situ, which provides a measure of the spatial distribution of bubble velocities and sizes at regular time intervals. The flow exhibits a rich phenomenology including preferential flow paths and local flow nonstationarity (intermittency) despite the imposed permanent global flow rate. Moreover, the medium selects the bubble size distribution through lamella division-triggered bubble fragmentation. Varying the mean bubble size of the injected foam, its water content, and mean velocity, we characterize those processes systematically. In particular, we measure the spatial evolution of the distribution of bubble areas, and infer the efficiency of bubble fragmentation depending on the various control parameters. We furthermore show that the distributions of bubble sizes and velocities are correlated. This study sheds new light on the local rheology of foams in porous media and opens the way toward quantitative characterization of the relationship between medium geometry and foam flow properties. It also suggests that large-scale models of foam flows in the subsurface should account for the correlation between bubble sizes and velocities

This paper reports findings from the first two phases of a cohort study completed just before and at the start of the pandemic, which track Scottish Education students’ reflections on social justice at one university. We used three focus groups (n = 14) and surveys to analyse students’ (n = 45) definitions of social justice. Using Bronfenbrenner’s Ecological System’s Theory and Saldana’s Analytical Coding framework we found that themes around prejudice, culture, policy, and emerging professional identity captured participants’ reflections as both beginning teachers and students of educational studies. Key to our findings was that fewer reflections of social justice were cited to global than to local contexts. This paper highlights ways in which university educators may conceive of social justice such that it is considered by students in both their immediate and in global contexts.https://journals.sagepub.com/home/esjinpressinpres

Imprecise recombinant viruses evolve via a fitness-driven, iterative process of polymerase template-switching events

One of these is the process of recombination involving the large-scale exchange of genetic information. Recombination occurs during replication when the viral polymerase, bound to the nascent RNA chain, switches from copying one genome to another. However, the polymerase does not always accurately switch between the two, resulting in sequence duplications or deletions, and genomes that are referred to as imprecise. Over multiple rounds of replication sequence duplications are lost and genomes are resolved to wild type length, but it is unclear how this occurs. Here we used synthetic polioviruses containing defined sequence duplications to determine that the genome population undergoes repeated rounds of recombination until sequence duplications are lost and viruses with precise, wild type length genomes are selected for. This selection is based on the overall fitness of the virus population, with less fit imprecise viruses evolving more quickly. Our study suggests that recombination is a continual process where virus fitness drives the selection of a small subset of recombinant variants. These data are important for understanding how novel viruses evolve via recombination and how this process can be blocked to prevent novel and dangerous pathogens from arising.Publisher PDFPeer reviewe
