“First time here, I didn’t know it was hospital”. Travelling for treatment: The structural complexities identified via the stories of Aboriginal women who relocated for treatment in the State Adult Burns Unit at Fiona Stanley Hospital.

Background: International and national research confirms the disparity in life expectancy between Aboriginal and non-Aboriginal populations. Inequity of access to healthcare for remote and very remote Aboriginal people makes relocation for specialist medical services a necessity. The aim of this research is to investigate the effects of relocation on Aboriginal patients admitted to the State Adult Burn Unit at Fiona Stanley Hospital. Aims: This qualitative study sought to define and describe this experience of relocation, with a strong focus on structural complexities. Aboriginal women were asked to describe their experiences of relocating from remote and very remote communities to the State Adult Burns Unit for treatment. In addition, information was also sought on the participants’ experience of isolation from family, whilst in the State Adult Burns Unit. Methods: A case series used qualitative data collected from three semi structured interviews by ‘yarning’. These were conducted by the researcher and in the presence of an Aboriginal Hospital Liaison Officer. Thematic data analysis and cross-case analysis was used to identify themes in the participants’ experiences. Results: Four main themes emerged which had layered complexities. Firstly, communication difficulties with health staff, secondly, prolonged travel, including multiple modes of travel to reach Perth, and thirdly, concerns related to maintaining contact with family. Participants also discussed receiving good care within the Burns Unit both from staff, and complimented the quality of the hospital meals. Recommendations: Six recommendations arose that aimed to address these three themes; to improve difficulties with communication with health staff, to ensure that ongoing contact with family was optimised, and to assist with transport difficulties. Practical solutions, such as upskilling for relevant health staff, consideration for referral to an Aboriginal Health Liaison Officer for all remote Aboriginal patients, and providing remote patients and their families with the correct address and contact details of the State Adult Burns Unit, prior to travel to Perth improve ongoing family contact. Despite the restricted sample size, rich data was extracted, which will be used to promote best practice for future remote and very remote Aboriginal burn patients via the implementation of the recommendations, commencing with education initiatives for staff, to address communication challenges

Family-centered rounds and medical student performance on the NBME pediatrics subject (shelf) examination: a retrospective cohort study

Objective To determine the association between family-centered rounds (FCR) and medical student knowledge acquisition as assessed by the National Board of Medical Examiners (NBME) pediatric subject (shelf) exam. Methods A retrospective cohort study was conducted of third-year medical students who graduated from Virginia Commonwealth University School of Medicine between 2009 and 2014. This timeframe represented the transition from ‘traditional’ rounds to FCR on the pediatric inpatient unit. Data collected included demographics, United States Medical Licensing Examination (USMLE) Step 1 and 2 scores, and NBME subject examinations in pediatrics (PSE), medicine (MSE), and surgery (SSE). Results Eight hundred and sixteen participants were included in the analysis. Student performance on the PSE could not be statistically differentiated from performance on the MSE for any year except 2011 (z-score=−0.17, p=0.02). Average scores on PSE for years 2009, 2010, 2013, and 2014 were significantly higher than for SSE, but not significantly different for all other years. The PSE was highly correlated with USMLE Step 1 and Step 2 examinations (correlation range 0.56–0.77) for all years. Conclusions Our results showed no difference in PSE performance during a time in which our institution transitioned to FCR. These findings should be reassuring for students, attending physicians, and medical educators

Community control of education : how the Mohawk community of Kahnawake is reclaiming their schools

This study is an ethnographic exploration of the measures taken by the Mohawk community of Kahnawake to reclaim the education of their youth and of the role that education plays in achieving their self-determination. Through a combination of fieldwork, interviews with teachers, parents, and school administrators, the research is intended to document the challenges that the community faces and the different strategies adopted to overcome them. The legacy of residential schools and the attempt to obliterate Indigenous cultures and languages, continues to keep education and schooling at the centre of Kahnawake's struggle to maximize self-determination. The Kahnawake community continues to define educational curriculum and content. Members express enthusiasm in providing youth with the necessary tools to protect their culture and autonomy by attempting to seek community consensus on curriculum content. Achieving consensus though, can prove difficult as seen by the demise of the Educational Park project. Nonetheless, by examining the Youth Conference and the Entrepreneurial Workshops, this thesis details how Kahnawake schools have been able to respond to the needs of its students. The community's effort to assume control of their education system has created an opportunity to reclaim their history, traditions, and language through a process of decolonization. Through this process, the community is able to assert responsibility for any developments made, which is an essential part of community control of education

The Effects of Object Shape, Fidelity, Color, and Luminance on Depth Perception in Handheld Mobile Augmented Reality

Depth perception of objects can greatly affect a user's experience of an augmented reality (AR) application. Many AR applications require depth matching of real and virtual objects and have the possibility to be influenced by depth cues. Color and luminance are depth cues that have been traditionally studied in two-dimensional (2D) objects. However, there is little research investigating how the properties of three-dimensional (3D) virtual objects interact with color and luminance to affect depth perception, despite the substantial use of 3D objects in visual applications. In this paper, we present the results of a paired comparison experiment that investigates the effects of object shape, fidelity, color, and luminance on depth perception of 3D objects in handheld mobile AR. The results of our study indicate that bright colors are perceived as nearer than dark colors for a high-fidelity, simple 3D object, regardless of hue. Additionally, bright red is perceived as nearer than any other color. These effects were not observed for a low-fidelity version of the simple object or for a more-complex 3D object. High-fidelity objects had more perceptual differences than low-fidelity objects, indicating that fidelity interacts with color and luminance to affect depth perception. These findings reveal how the properties of 3D models influence the effects of color and luminance on depth perception in handheld mobile AR and can help developers select colors for their applications.Comment: 9 pages, In proceedings of IEEE International Symposium on Mixed and Augmented Reality (ISMAR) 202

B Cell IgD Deletion Prevents Alveolar Bone Loss Following Murine Oral Infection

Periodontal disease is one of the most common infectious diseases of humans. Immune responses to infection trigger loss of alveolar bone from the jaw and eventual tooth loss. We investigated the contribution of B cell IgD to alveolar bone loss by comparing the response of B cell normal BALB/cJ mice and IgD deficient BALB/c-Igh-5−/−J mice to oral infection with Porphyromonas gingivalis, a gram-negative periodontopathic bacterium from humans. P. gingivalis-infected normal mice lost bone. Specific antibody to P. gingivalis was lower and oral colonization was higher in IgD deficient mice; yet bone loss was completely absent. Infection increased the proportion of CD69+ activated B cells and CD4+ T cells in immune normal mice compared to IgD deficient mice. These data suggest that IgD is an important mediator of alveolar bone resorption, possibly through antigen-specific coactivation of B cells and CD4+ T cells
