Social media, eating disorders and recovery

Social media use is rapidly increasing; whilst the dangers of using social media have been highlighted by previous research, less attention has been paid to the positive influences of social media. This study aimed to explore experiences of using social media in people recovering from an eating disorder (ED). Objectives were to understand how people with EDs use social media in relation to their ED and recovery, and the perceived helpful and unhelpful aspects of using social media during their recovery. In depth interviews with 15 adults (aged 19-40) recovering from an ED were thematically analysed. Participants also shared examples of social media posts that were helpful and less helpful in their recovery, which were included in the thematic analysis. Four key themes were identified: motivating recovery, a supportive space to share and be open, maintains difficulties, and navigating social media. Participants’ social media use appeared to change dependent on their motivations, needs, and stages of recovery. Findings have important implications for clinical practice, working alongside, not against, social media use in those with EDs. Further research is needed in order to greater understand the role social media plays during the recovery process

A micro-radioimmunoassay for measurement of rat luteinizing hormone

A sensitive and reproducible double antibody radio-immunoassay for rat LH measurement, which requires at most 50μl  of serum or plasma per tube, is described for use with 125l and rabbit anti-rat LH serum. The assay has a scnsitivity of 16 ng LH/ml, and coefficients of inter-assay and intra-assay variations of +/-6,6% and +/-3.1% respectively. The possible diffusion of the constituentsof the incubate through the walls of the plastic micro tube used, as described by others, was not significant. Normal basal LH values for albino rats are described together with their serum LH responses to various doses of LR

An evaluation of a student led career profiling project to support the exploration of a career in general practice and other specialties

BACKGROUND: Choosing medical careers is complex but the undergraduate period is formative. St. George’s University of London (SGUL) students called for greater careers information. AIM: To develop & evaluate students’ careers resources. DESIGN & SETTING: A quality improvement student staff project at SGUL. METHOD: A “Plan, Do, Study, Act” (PDSA) cycle was completed. For the “Plan” element we surveyed students’ career intentions and information preferences. For the “Do” element, video interviews with clinicians and infographic posters were produced and published on SGUL’s virtual learning environment. For the “Study” element, feedback questionnaires were thematically analysed using Kirkpatrick’s framework. For the “Act” element the model was rolled out across SGUL programmes. RESULTS: (Plan) 79 students ranked interest in specialties, with GP second most popular. Students were unconfident how to pursue careers and wanted more information. (Do) 13 careers videos & infographics were created for 10 specialties. The (Study) questionnaire showed changes across 3 of Kirkpatrick’s levels. Level 1 (Response) students found resources helpful & accessible. Level 2 (Learning) students reported increased understanding of careers. Level 3 (Transfer) students planned using checklists and made career comparisons by specialty. Level 4 (Results) students’ career choices were not demonstrated but there were tentative proxy measures such as copying and modelling career routes and choices. (Act) involved rolling out and regularly updating resources. CONCLUSION: This PDSA model enabled development of resources by students mapped to students’ needs. We demonstrated changes in relation to students’ response, learning and transfer, with tentative suggestions of impact on career choice

Evolving structures of star-forming clusters

Understanding the formation and evolution of young star clusters requires quantitative statistical measures of their structure. We investigate the structures of observed and modelled star-forming clusters. By considering the different evolutionary classes in the observations and the temporal evolution in models of gravoturbulent fragmentation, we study the temporal evolution of the cluster structures. We apply different statistical methods, in particular the normalised mean correlation length and the minimum spanning tree technique. We refine the normalisation of the clustering parameters by defining the area using the normalised convex hull of the objects and investigate the effect of two-dimensional projection of three-dimensional clusters. We introduce a new measure $\xi$ for the elongation of a cluster. It is defined as the ratio of the cluster radius determined by an enclosing circle to the cluster radius derived from the normalised convex hull. The mean separation of young stars increases with the evolutionary class, reflecting the expansion of the cluster. The clustering parameters of the model clusters correspond in many cases well to those from observed ones, especially when the $\xi$ values are similar. No correlation of the clustering parameters with the turbulent environment of the molecular cloud is found, indicating that possible influences of the environment on the clustering behaviour are quickly smoothed out by the stellar velocity dispersion. The temporal evolution of the clustering parameters shows that the star cluster builds up from several subclusters and evolves to a more centrally concentrated cluster, while the cluster expands slower than new stars are formed.Comment: 11 pages, 10 figures, accepted by A&A; slightly modified according to the referee repor
