Black and Asian police officers and support staff: prejudice, identity, agency and social cohesion

This primary research paper presents a review of research that finds that the British Government’s new social cohesion agenda does hold promise for racial and ethnic prejudice reduction – but that social cohesion policies and practice must include at their core policies to reduce institutional racism in British police services. Analysis of the literature reveals that considerably more research is required to examine the precise nature and dynamics of institutional racism within the police services. There is a need to understand how racism against Black and minority ethnic (BME) police employees, and police racism against BME communities, influences social cohesion. That this is important, given the British government’s current social cohesion policy agenda, is patently clear. Considerably more research is about to be undertaken in this area by the authors of this paper and the results will be published in the academic press, disseminated at conferences and presented in training programmes

Diasporic Literary Archives Network and the Commonwealth: Namibia, Nigeria, Trinidad & Tobago, and other examples

This article brings together three themes: primary sources for the study of literature; the diasporic nature of literary manuscripts; and the impact of the diaspora on the English-speaking world, in general, and the Commonwealth, in particular. The article begins by describing some general characteristics of literary manuscripts, focusing in particular on their diasporic nature. It then outlines the work of the project known as the Diasporic Literary Archives Network in the years 2012-15. It concludes with an assessment of the archival diaspora as it affects cultural and literary heritage work in Commonwealth countries

Systematic review and meta-analysis. small intestinal bacterial overgrowth in chronic pancreatitis

BACKGROUND: Evidence on small intestinal bacterial overgrowth (SIBO) in patients with chronic pancreatitis (CP) is conflicting. AIM: The purpose of this study was to perform a systematic review and meta-analysis on the prevalence of SIBO in CP and to examine the relationship of SIBO with symptoms and nutritional status. METHODS: Case-control and cross-sectional studies investigating SIBO in CP patients were analysed. The prevalence of positive tests was pooled across studies, and the rate of positivity between CP cases and controls was calculated. RESULTS: In nine studies containing 336 CP patients, the pooled prevalence of SIBO was 36% (95% confidence interval (CI) 17-60%) with considerable heterogeneity (I2 = 91%). A sensitivity analysis excluding studies employing lactulose breath test gave a pooled prevalence of 21.7% (95% CI 12.7-34.5%) with lower heterogeneity (I2 = 56%). The odds ratio for a positive test in CP vs controls was 4.1 (95% CI 1.6-10.4) (I2 = 59.7%). The relationship between symptoms and SIBO in CP patients varied across studies, and the treatment of SIBO was associated with clinical improvement. CONCLUSIONS: One-third of CP patients have SIBO, with a significantly increased risk over controls, although results are heterogeneous, and studies carry several limitations. The impact of SIBO and its treatment in CP patients deserve further investigation

NASA MSFC hardware in the loop simulations of automatic rendezvous and capture systems

Two complementary hardware-in-the-loop simulation facilities for automatic rendezvous and capture systems at MSFC are described. One, the Flight Robotics Laboratory, uses an 8 DOF overhead manipulator with a work volume of 160 by 40 by 23 feet to evaluate automatic rendezvous algorithms and range/rate sensing systems. The other, the Space Station/Station Operations Mechanism Test Bed, uses a 6 DOF hydraulic table to perform docking and berthing dynamics simulations

Simple threshold rules solve explore/exploit trade‐offs in a resource accumulation search task

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold‐based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non‐decreasing thresholds. Decreasing threshold strategies that “front‐load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration

Impacts of a professional practice doctorate: a collaborative enquiry

Doctoral education aims to benefit those who undertake it, but does it exert a wider influence? Professional doctorates are commonly designed to have an impact beyond the individual concerned, but is this influence realised? This paper focuses on a collaborative enquiry by a group of academics and doctoral alumni from non-discipline-specific professional doctorates. The enquiry examined how the professional practice of the graduates changed as a result of their studies and what influence this had on their work and their profession. It found that there was considerable impact on the wider context of the alumni, but that these effects were due more to the capacity-building effect of the doctorate than on the particular outcomes of the study undertaken. Key words: doctoral education, research impact, collaborative enquiry, professional practic

A comparison between omeprazole and a dietary supplement for the management of squamous gastric ulceration in horses

Although several studies have assessed the short-term effect of dietary supplements on the treatment and prevention of gastric ulceration in horses, few have assessed the response over a duration of more than 30 days. A blinded randomized noninferiority clinical trial was conducted using 42 Thoroughbred horses in race training with squamous ulceration of ≥ grade 2/4, randomly assigned to one of two treatment groups for a period of 90 days: omeprazole at the full label dose of 4 mg/kg or the Succeed digestive conditioning supplement. Noninferiority analyses and Wilcoxon sign rank tests were used to analyze the data. At day 90, Succeed was noninferior to 4 mg/kg omeprazole administered daily in terms of the proportion of horses with complete resolution of squamous ulceration. At day 30, Succeed was found to be inferior to omeprazole in terms of the proportion of horses with grade ≤1/4 squamous ulceration. The proportion of horses with reducing squamous ulcer score (compared with day 0) was statistically significant for both treatments at days 30 and 60. At day 90 of the 17 horses on Succeed, nine had a reducing squamous ulcer score (P value = .049), and of the 19 horses on omeprazole, 10 had a reducing squamous ulcer score at day 90 (P value = .091). The noninferiority of Succeed compared to omeprazole at 90 days for the complete resolution of squamous ulceration and the reduced efficacy of omeprazole following 90 days of treatment are likely to be of interest to practitioners managing gastric ulceration in performance horses

Navigating collaborative governance:Network ignorance and the performative planning of South Australia's emergency management

This paper examines the roles for emergency and disaster risk management plans as policy artefacts that guide centralised governance networks. Past scholarship has been sceptical of the instrumental worth of these artefacts for informing and elaborating governance arrangements. Some suspect that such plans are purely symbolic devices, mere ‘fantasy documents’. This paper examines the role of South Australia's state emergency management plan during the Black Summer bushfires of 2019–2020. The study provides confirmation of the symbolic utility of these plans for central government, while also providing evidence for some suggested difficulties with centralised emergency management networks, about which there is still limited empirical demonstration. Drawing on focus group and interview testimony from senior actors at strategic, tactical and operational levels of South Australia's emergency network, however, we also demonstrate instrumental-heuristic worth of these plans for network actors seeking to make sense of a continually changing bureaucratic landscape, and when reflecting on the value of the network in the aftermath of extreme events
