Creating continuity out of the disruption of a diagnosis of HIV during pregnancy

AIM: To understand the uniqueness of the experience of testing HIV positive from the perspective of pregnant women.

BACKGROUND: As more people learn of their HIV diagnosis through routine screening processes, it is timely to reflect on the impact of receiving an unexpected positive result.

DESIGN: A prospective qualitative study.

METHODS: This paper draws on the case studies of four women who were participating in a larger prospective qualitative study of reproductive decision-making, pregnancy and childbirth following HIV diagnosis. Multiple interviews were conducted following diagnosis during pregnancy, and, after the birth of their babies. Thematic data analysis was undertaken.

RESULTS: Drawing on Becker's theory of disruption, we document the 'sudden disjuncture' of their antenatal diagnosis and the embodied emotional struggle the women engaged in to create continuity in their lives. A diagnosis of HIV disrupted the women's biographies in terms of their health, relationships and social identity. As pregnant women, the threat of HIV was experienced most significantly in relation to their unborn child. However, their narratives also revealed how a diagnosis of HIV in the context of pregnancy, whilst traumatic, provided a focus for regaining continuity in their lives, as the baby became a metaphor for hope and orientation toward the future.

CONCLUSIONS: As HIV testing becomes more 'routine', the findings of this study serve to remind health professionals that a positive diagnosis continues to constitute a major trauma to individuals and families.

RELEVANCE TO CLINICAL PRACTICE: We propose that appropriately educated nursing and midwifery staff could facilitate the 'meaning making' process that is required for newly diagnosed HIV positive persons to find a subjective sense of well-being in their lives.

Connected Life Courses:Influences on and Experiences of 'Midlife' In-Migration to Rural Areas

This paper aims to contribute to the theorisation of midlife migration into rural areas. Although the factors influencing migration are known to be variable at different stages of a person's life, much less well understood is how migration decisions at different stages of the life course are connected and how post-migration experiences may be influenced by an earlier life course stage. We argue that midlife migration decisions are the product of the migrant's lifetime experiences and influences up until that stage in their life alongside their expectations and aspirations for future life course stages. Using a case study of the Glens of Antrim (Northern Ireland), this paper specifically demonstrates the role of childhood memories to explain midlife migration to a rural area. In doing so, it argues that some findings more commonly associated with second-generation transnational migration are also equally relevant to migration within the UK. Roots migration and place attachment alongside the midlife migrant's post-migration sense of belonging and permanency are found to be influenced by the migrant's earlier memories, behaviours, and experiences.

Ruling out a massive asymptotic giant-branch star as the progenitor of supernova 2005cs

We calculate the predicted UBVRIJHK absolute magnitudes for models of supernova progenitors and apply the result to the case of supernova 2005cs. We agree with previous results that the initial mass of the star was low, around 6 to 8 M-circle dot. However, such stars are thought to go through a second dredge-up to become asymptotic giant branch (AGB) stars. We show that had this occurred to the progenitor of 2005cs it would have been observed in JHK pre-explosion images. The progenitor was not detected in these bands and therefore we conclude that it was not an AGB star. Furthermore, if some AGB stars do produce supernovae they will have a clear signature in pre-explosion near-infrared images. Electron-capture supernovae are thought to occur in AGB stars, hence the implication is that 2005cs was not an electron-capture supernova but was the collapse of an iron core.

NE-LIKE GE SLAB TARGET STUDIES CARRIED OUT AT RAL

The effect of non-uniform target illumination on the soft X-ray lasing output intensity of the J=2-1 Ne-like Ge transitions as a function of length was investigated. As the degree of nonunifonnity increased with length the Ne-like Ge 23.2 and 23.6 nm J=2-1 transitions did not show exponentiation of output intensity. Using an experimentally measured gain-intensity scaling relationship these results were modelled and good qualitative agreement obtained. The model indicates that for Ge targets which are non-uniformly illuminated, even with peak to valley ratios of up to 3 efficient operation can be achieved at between 2-3x threshold intensity. Further studies of the effect of increasing the separation between the two targets of a double target geometry are also presented.
