A 2.15 Hour Orbital Period for the Low Mass X-Ray Binary XB 1832-330 in the Globular Cluster NGC 6652

We present a candidate orbital period for the low mass X-ray binary XB 1832-330 in the globular cluster NGC 6652 using a 6.5 hour Gemini South observation of the optical counterpart of the system. Light curves in g' and r' for two LMXBs in the cluster, sources A and B in previous literature, were extracted and analyzed for periodicity using the ISIS image subtraction package. A clear sinusoidal modulation is evident in both of A's curves, of amplitude ~0.11 magnitudes in g' and ~0.065 magnitudes in r', while B's curves exhibit rapid flickering, of amplitude ~1 magnitude in g' and ~0.5 magnitudes in r'. A Lomb-Scargle test revealed a 2.15 hour periodic variation in the magnitude of A with a false alarm probability less than 10^-11, and no significant periodicity in the light curve for B. Though it is possible saturated stars in the vicinity of our sources partially contaminated our signal, the identification of A's binary period is nonetheless robust.Comment: 7 pages, 7 figures, ApJ in pres

The normalisation of drug supply: The social<i>supply</i>of drugs as the “other side” of the history of normalisation

Aims: Describes how the relative normalisation of recreational drug use in the UK has been productive of, and fused with, the relatively normalised and non-commercial social supply of recreational drugs. Methods: Semi-structured interviews with 60 social suppliers of recreational drugs in two studies (involving a student population n = 30 and general population sample n = 30). Respondents were recruited via purposive snowball sampling and local advertising. Findings: Both samples provided strong evidence of the normalised supply of recreational drugs in micro-sites of friendship and close social networks. Many social suppliers described “drift” into social supply and normalised use was suggested to be productive of supply relationships that both suppliers and consumers regard as something less than “real” dealing in order to reinforce their preconceptions of themselves as relatively non-deviant. Some evidence for a broader acceptance of social supply is also presented. Conclusions: The fairly recent context of relative normalisation of recreational drug use has coalesced with the social supply of recreational drugs in micro-sites of use and exchange whereby a range of “social” supply acts (sometimes even involving large amounts of drugs/money) have become accepted as something closer to gift-giving or friendship exchange dynamics within social networks rather than dealing proper. To some degree, there is increasing sensitivity to this within the criminal justice system

The epidemiology of reoperations for orthopaedic trauma.

Introduction: The Royal College of Surgeons of England (RCS) has issued guidance regarding the use of reoperation rates in the revalidation of UK-based orthopaedic surgeons. Currently, little has been published concerning acceptable rates of reoperation following primary surgical management of orthopaedic trauma, particularly with reference to revalidation. / Methods: A retrospective review was conducted of patients undergoing clearly defined reoperations following primary surgical management of trauma between 1 January 2010 and 31 December 2011. A full case note review was undertaken to establish the demographics, clinical course and context of reoperation. A review of the imaging was performed to establish whether the procedure performed was in line with accepted trauma practice and whether the technical execution was acceptable. / Results: A total of 3,688 patients underwent primary procedures within the time period studied while 70 (1.90%, 99% CI: 1.39–2.55) required an unplanned reoperation. Thirty-nine (56%) of these patients were male. The mean age of patients was 56 years (range: 18–98 years) and there was a median time to reoperation of 50 days (IQR: 13–154 days). Potentially avoidable reoperations occurred in 41 patients (58.6%, 99% CI: 43.2–72.6). This was largely due to technical errors (40 patients, 57.1%, 99% CI: 41.8–71.3), representing 1.11% (99% CI: 0.73–1.64) of the total trauma workload. Within RCS guidelines, 28-day reoperation rates for hip, wrist and ankle fractures were 1.4% (99% CI: 0.5–3.3), 3.5% (99% CI: 0.8%–12.1) and 1.86% (99% CI: 0.4–6.6) respectively. / Conclusions: We present novel work that has established baseline reoperation rates for index procedures required for revalidation of orthopaedic surgeons

Gap-induced reductions of evoked potentials in the auditory cortex: a possible objective marker for the presence of tinnitus in animals

Animal models of tinnitus are essential for determining the underlying mechanisms and testing pharmacotherapies. However, there is doubt over the validity of current behavioural methods for detecting tinnitus. Here, we applied a stimulus paradigm widely used in a behavioural test (gap-induced inhibition of the acoustic startle reflex GPIAS) while recording from the auditory cortex, and showed neural response changes that mirror those found in the behavioural tests. We implanted guinea pigs (GPs) with electrocorticographic (ECoG) arrays and recorded baseline auditory cortical responses to a startling stimulus. When a gap was inserted in otherwise continuous background noise prior to the startling stimulus, there was a clear reduction in the subsequent evoked response (termed gap-induced reductions in evoked potentials; GIREP), suggestive of a neural analogue of the GPIAS test. We then unilaterally exposed guinea pigs to narrowband noise (left ear; 8-10 kHz; 1 hour) at one of two different sound levels - either 105 dB SPL or 120 dB SPL – and recorded the same responses seven-to-ten weeks following the noise exposure. Significant deficits in GIREP were observed for all areas of the auditory cortex (AC) in the 120 dB-exposed GPs, but not in the 105 dB-exposed GPs. These deficits could not simply be accounted for by changes in response amplitudes. Furthermore, in the contralateral (right) caudal AC we observed a significant increase in evoked potential amplitudes across narrowband background frequencies in both 105 dB and 120 dB-exposed GPs. Taken in the context of the large body of literature that has used the behavioural test as a demonstration of the presence of tinnitus, these results are suggestive of objective neural correlates of the presence of noise-induced tinnitus and hyperacusis

Isolation of Angola-like Marburg virus from Egyptian rousette bats from West Africa.

Marburg virus (MARV) causes sporadic outbreaks of severe Marburg virus disease (MVD). Most MVD outbreaks originated in East Africa and field studies in East Africa, South Africa, Zambia, and Gabon identified the Egyptian rousette bat (ERB; Rousettus aegyptiacus) as a natural reservoir. However, the largest recorded&nbsp;MVD outbreak with the highest case-fatality ratio happened in 2005 in Angola, where direct spillover from bats was not&nbsp; shown. Here, collaborative studies by the Centers for Disease Control and Prevention, Njala University, University of California, Davis USAID-PREDICT, and the University of Makeni identify MARV circulating in ERBs in Sierra Leone. PCR, antibody and virus isolation data from 1755 bats of 42 species shows active MARV infection in approximately 2.5% of ERBs. Phylogenetic analysis identifies MARVs that are similar to the Angola strain. These results provide evidence of MARV circulation in West Africa and demonstrate the value of pathogen surveillance to identify previously undetected threats

Sourcing illegal drugs as a hidden older user: the ideal of ‘social supply’

Aims: At a time of growing awareness regarding the non-commercial supply of illegal drugs between friends, this article explores the significance of so-called ‘social supply’ for a group of ‘hidden’ users of illegal drugs aged 40 and over. Methodology: Semi-structured interviews were conducted with 30 users of illegal drugs aged 40 and over who were not in contact with the criminal justice system or treatment agencies regarding their use. Participants were recruited using snowball sampling. Findings: Accessing drugs through the commercial market was considered as a less attractive proposition than social supply by the participants. The majority used only socially supplied drugs, with some engaging commercial dealers when socially supplied product was unavailable. A handful sourced drugs exclusively through the commercial market. Some were home growers of cannabis, and a small number had drifted into social supply themselves. Conclusions: Social supply was seen in a far more favourable light than commercial transactions by our participants, and acted as an ideal against which all other acts of sourcing were compared. Moreover, social supply was often an integral facet of the drug using experience and served to validate and enhance that experience. The relatively benign, non-predatory nature of the social supply engaged in by the participants lends support to calls for some reform of the offence of supply in UK law

‘You can’t stand on a corner and talk about it …’: Medicinal cannabis use, impression management and the analytical status of interviews

In this article, I examine how four medicinal cannabis users used impression management during in-depth, qualitative interviews to attend to self-presentational concerns. I examine the rhetorical strategies and narratives articulated by the participants while also attending to the role that I played in co-construction as the interviewer. Later I discuss how, although the participants’ accounts are occasioned by the interviews, they can still provide significant insights into the social worlds of the participants beyond the interviews. While discussions about whether to treat interviews as topic, resource or both are not new, I argue that we can treat interviews as both topic and resource because impression management is a product of the individual’s habitus and it and the accounts it produces are part of their social world
