From snap to selfcare : reading feminism through Sara Ahmed and Phoebe Boswell

How can we bring two feminist bodies of work that operate through different media into meaningful conversation with one another? Using Fournier’s framework of autotheory, we work through this question by reading Sara Ahmed’s critical theory and Phoebe Boswell’s creative practice connectively, tracing intersectional feminist pedagogies and key concepts common to both as we go. Instead of applying critical theory to creative practices, we use creative practices as a tool to better understand how theory can be in ‘touch’ with the world. Co-writing this article is an initial step in seeking out the creative and embodied aspects of our own practice as feminist researchers.PostprintPeer reviewe

Prevocational integrated extended rural clinical experience (PIERCE): cutting through the barriers to prevocational rural medical education

Introduction: Despite an increase in the number of undergraduate training positions, Australia faces a critical shortage of medical practitioners in regional, rural and remote communities. Extended rural clinical placements have shown great utility in undergraduate medical curricula, increasing training capacity and providing comparable educational outcomes while promoting rural medicine as a career. The Prevocational Integrated Extended Rural Clinical Experience (PIERCE) was developed to increase the training capacity of the Queensland Rural Generalist Pathway (QRGP) and strengthen trainee commitment to rural practice by offering an authentic, extended 15-week rural term that provided an integrated experience in anaesthetics, obstetrics and gynaecology, and paediatrics, while meeting the requirements for satisfactory completion of prevocational rural generalist training. This study sought to evaluate whether trainees believed PIERCE and/or traditional regional hospital specialty placements achieved their learning objectives and to identify elements of the placements that contributed to, or were a barrier to, their realisation. Methods: This translational qualitative study explored the experiences and perceptions of QRGP trainees who undertook a PIERCE placement in three Queensland rural hospitals (Mareeba, Proserpine and Stanthorpe) in 2015, with a matched cohort of trainees who undertook regional hospital placements in anaesthetics, obstetrics and gynaecology, and paediatrics at a regional referral hospital (Cairns, Mackay and Toowoomba base hospitals). The study used a realist evaluation framework that investigates What works, for whom, in what circumstances, in what respects and why? Results: PIERCE provided an enjoyable and valued rural training experience that promoted trainee engagement with, and contribution to, a rural community of practice, reinforcing their commitment to a career in rural medicine. However, QRGP trainees did not accept that PIERCE could be a substitute for regional hospital experience in anaesthetics, obstetrics and gynaecology, and paediatrics. Rather, trainees thought PIERCE and regional hospital placements offered complementary experiences. PIERCE offered integrated, hands-on rural clinical experience in which trainees had more autonomy and responsibility. Regional hospital placements offered more traditional caseload learning experiences based on observation and the handing down of knowledge and skills by hospital-based supervisors. Conclusion: Both PIERCE and regional hospital placements provided opportunities and threats to the attainment of the curriculum objectives of the Australian Curriculum Framework for Junior Doctors, the Australian College of Rural and Remote Medicine and the Royal Australian College of General Practitioners Fellowship in Advanced Rural General Practice curricula. PIERCE trainees enjoyed the opportunity to experience rural medicine in a community setting, a broad caseload, hands-on proficiency, continuity of care and an authentic role as a valued member of the clinical team. This was reinforced by closer and more consistent clinical and educational interactions with their supervisors, and learning experiences that address key weaknesses identified in current hospital-based prevocational training. Successful achievement of prevocational curriculum objectives is contingent on strategic alignment of the curricula with supportive learning mechanisms focused by the learning context on the desired outcome, rural practice. This study adds weight to the growing consensus that rural community-based placements such as PIERCE are desirable components of prevocational training

Liquid-Crystal-Based Controllable Attenuators Operating in the 1-4 Terahertz Band

Liquid-crystal devices (LCDs) offer a potential route toward adaptive optical components for use in the < 2 THz band of the electromagnetic spectrum. We demonstrate LCDs using a commercially available material (E7), with unbiased birefringence values of 0.14-0.18 in the 0.3-4 THz band. We exploit the linear dichroism of the material to modulate the emission from a 3.4-THz quantum cascade laser by up to 40%, dependent upon both the liquid-crystal layer thickness and the bias voltage applied.Comment: 10 pages, 6 figure

Complementary and Alternative Medicine (CAM) Attitudes and Competencies of Nursing Students and Faculty: Results of Integrating CAM Into the Nursing Curriculum

As part of the National Center for Complementary and Alternative Medicine (CAM) R25 Education Grant Program, a faculty development program for integrating CAM into the nursing curriculum was instituted in 2003-2006. The Integrating CAM program comprised a number of elements; the primary strategy included a series of 4-week didactic and experiential summer CAM “camps,” attended by a total of 27 faculty members. Camps were designed to influence faculty integration of CAM material into course offerings. The Integrating CAM program was evaluated via a series of faculty and student surveys regarding CAM competencies, attitudes, and perceptions. For more than half of the faculty (out of the 43 who responded), the program yielded a moderate-to-strong influence on incorporation of CAM material into course content; and moderate-to-great increases in both enthusiasm for CAM and perceived CAM knowledge gains. Students at all levels (undergraduate, masters, doctoral; n = 184) reported that their courses contained CAM content; for 70% of students, their CAM knowledge increased; for 50% of students, level of CAM interest increased. Self-reported student CAM competencies were significantly greater in 2006-2007 (n = 191) than in 2003-2004 (n = 143). Results support the strategy of broadly infusing the nursing curriculum with CAM content via faculty development

Differential effects of FODMAPs (Fermentable Oligo-, Di-, Mono-Saccharides and Polyols) on small and large intestinal contents in healthy subjects shown by MRI

OBJECTIVES: The objective of this study was to investigate whether ingestion of fructose and fructans (such as inulin) can exacerbate irritable bowel syndrome (IBS) symptoms. The aim was to better understand the origin of these symptoms by magnetic resonance imaging (MRI) of the gut. METHODS: A total of 16 healthy volunteers participated in a four-way, randomized, single-blind, crossover study in which they consumed 500 ml of water containing 40 g of either glucose, fructose, inulin, or a 1:1 mixture of 40 g glucose and 40 g fructose. MRI scans were performed hourly for 5 h, assessing the volume of gastric contents, small bowel water content (SBWC), and colonic gas. Breath hydrogen (H 2) was measured and symptoms recorded after each scan. RESULTS: Data are reported as mean (s.d.) (95 % CI) when normally distributed and median (range) when not. Fructose increased area under the curve (AUC) from 0 – 5 h of SBWC to 71 (23) l / min, significantly greater than for glucose at 36 (11 – 132) l / min ( P < 0.001), whereas AUC SBWC after inulin, 33 (17 – 106) l / min, was no different from that after glucose. Adding glucose to fructose decreased AUC SBWC to 55 (28) l / min ( P = 0.08) vs. fructose. Inulin substantially increased AUC colonic gas to 33 (20) l / min, signifi cantly greater than glucose and glucose + fructose (both P < 0.05). Breath H 2 rose more with inulin than with fructose. Glucose when combined with fructose signifi cantly reduced breath H 2 by 7,700 (3,121 – 12,300) p.p.m. / min relative to fructose alone ( P < 0.01, n = 13). CONCLUSIONS: Fructose but not inulin distends the small bowel with water. Adding glucose to fructose reduces the effect of fructose on SBWC and breath hydrogen. Inulin distends the colon with gas more than fructose, but causes few symptoms in healthy volunteers

The CCP4 suite: integrative software for macromolecular crystallography

The Collaborative Computational Project No. 4 (CCP4) is a UK-led international collective with a mission to develop, test, distribute and promote software for macromolecular crystallography. The CCP4 suite is a multiplatform collection of programs brought together by familiar execution routines, a set of common libraries and graphical interfaces. The CCP4 suite has experienced several considerable changes since its last reference article, involving new infrastructure, original programs and graphical interfaces. This article, which is intended as a general literature citation for the use of the CCP4 software suite in structure determination, will guide the reader through such transformations, offering a general overview of the new features and outlining future developments. As such, it aims to highlight the individual programs that comprise the suite and to provide the latest references to them for perusal by crystallographers around the world.Jon Agirre is a Royal Society University Research Fellow (UF160039 and URF\R\221006).

Comprehensive phenotypic analysis of the Dp1Tyb mouse strain reveals a broad range of Down syndrome-related phenotypes

Down syndrome (DS), trisomy 21, results in many complex phenotypes including cognitive deficits, heart defects and craniofacial alterations. Phenotypes arise from an extra copy of human chromosome 21 (Hsa21) genes. However, these dosage-sensitive causative genes remain unknown. Animal models enable identification of genes and pathological mechanisms. The Dp1Tyb mouse model of DS has an extra copy of 63% of Hsa21-orthologous mouse genes. In order to establish whether this model recapitulates DS phenotypes, we comprehensively phenotyped Dp1Tyb mice using 28 tests of different physiological systems and found that 468 out of 1800 parameters were significantly altered. We show that Dp1Tyb mice have wide-ranging DS-like phenotypes, including aberrant erythropoiesis and megakaryopoiesis, reduced bone density, craniofacial changes, altered cardiac function, a pre-diabetic state, and deficits in memory, locomotion, hearing and sleep. Thus, Dp1Tyb mice are an excellent model for investigating complex DS phenotype-genotype relationships for this common disorder
