Sharing and transforming our way of understanding the world

A Critical Theory of Technological Development (ENSC2601), is a broadening elective offered to all undergraduate students at UWA. Engineering, science, arts and humanities students together critique the past and present of engineering practice, and consider sustainable and just alternatives for the future. In 2015 UWA was approached by The Noongar Institute of WA (NIWA) for assistance in developing its teaching and learning resources for DIDARA WALGINER BURA MOGANG GUDJIR BALJARRA NIWA Centre for Excellence in Science and Technology. NIWA is an inclusive centre for community advancement promoting Noongar excellence, leadership and innovation of the Noongar Nation. Reconstruct was thus launched as a program of community service, through which UWA students work with local NIWA members, to understand Noongar culture, to share ideas about science and to develop news ways of thinking about engineering. It is an incredible opportunity for UWA students of many different disciplines to develop intercultural competencies and gain invaluable experience in working with complex, critical local issues but which also have global relevance and significance for their future careers. The first year of the program demonstrated the hugely transformational impact that this program can have on both students and community. I have been a University teacher and educational developer for over 20 years and in three continents, yet this was my most profound teaching experience. I hope to share with you some thoughts on why this might be. I found this incredibly beneficial. Its shaken the foundation of my belief system and I think the after shocks (questioning what I thought I knew) will reverberate through me for a long time after this unit finished (ENSC2601 student 2015) This morning I believed in hope once again. It was a gift I will treasure for myself. Thank you. The Community was thrilled and proud. I only wish I could show them how wonderful they (the students) all were.. they spoke with depth and genuine care about the project (the future of our world is in good hands (NIWA volunteer

Recent developments in UK Engineering Education are presented, together with a brief underlying philosophy, exploring a networking model to connect enthusiasts and provide support for their developments and innovations

The preferences and perspectives of family caregivers towards place of care for their relatives at the end-of-life. A systematic review and thematic synthesis of the qualitative evidence

Background Home is often reported as the preferred place of care for patients at the end-of-life. The support of family caregivers is crucial if this is to be realised. However, little is known about their preferences; a greater understanding would identify how best to support families at the end-of-life, ensuring more patients are cared for in their preferred location. Objectives To systematically search and synthesise the qualitative literature exploring the preferences and perspectives of family caregivers towards place of care for their relatives at the end-of-life. Methods Ten databases (MEDLINE, PsycINFO, EMBASE, AMED, ASSIA, CINAHL, Social Care Online, Cochrane Database, Scopus, Web of Science) and reference lists of key journals were searched up to January 2014. Included studies were appraised for quality and data thematically synthesised. Results Eighteen studies were included; all were of moderate or high quality. Two main themes were identified: (1) Preferences and perspectives: most family caregivers preferred home care, although a range of perspectives were reported. Both positive and negative perspectives of home, hospices and hospitals emerged. At times, family caregivers reported feeling obligated to provide home care. (2) Impact of facilitating home care; both positive and negative effects on family caregivers were reported. Conclusions Many family caregivers reported home as the preferred place of care; other places of care were infrequently considered. Healthcare professionals and service providers should be aware of these preferences and provide support where needed to enable family caregivers to successfully care at home, thus improving end-of-life experiences for families as a whole

Intensive Mode Teaching of a Humanitarian Engineering Course to Enhance Service-Learning

Service-learning is a common component of many humanitarian engineering education programs. Students engage with external organisations and communities, often spending time intensively, on projects linked to their studies. To help prepare students for substantial service-learning initiatives a dedicated humanitarian engineering course was developed. To better represent service-learning and enable a greater variety of teaching and learning activities, the course was delivered over five weeks using intensive mode teaching. This enabled a portion of the class to be involved with a two-week scaffolded immersive international experience running in parallel to the campus delivery. Threshold concept and capability theory was used to evaluate the course and identify what elements of the course supported or hindered development of student thresholds. Results identified the main student threshold to be the ability to take account of social factors in engineering design and the activities enabled by the intensive mode teaching were among the strongest contributions to the achievement of this threshold, in particular elements of the international experience. This highlights the opportunities for intensive mode teaching in supporting activities related to service-learnin

Global patterns of freshwater species diversity, threat and cross-taxon congruence

Aim Global-scale studies are required to identify broad-scale patterns in the distributions of species, to evaluate the processes that determine diversity and to determine how similar or different these patterns and processes are among different groups of freshwater species. Broad-scale patterns of spatial variation in species distribution are central to many fundamental questions in macroecology and conservation biology. We aimed to evaluate how congruent three commonly used metrics of diversity were among taxa for six groups of freshwater species. Location Global. Methods We compiled geographical range data on 7083 freshwater species of mammals, amphibians, reptiles, fishes, crabs and crayfish to evaluate how species richness, richness of threatened species and endemism are distributed across freshwater ecosystems. We evaluated how congruent these measures of diversity were among taxa at a global level for a grid cell size of just under 1°. Results We showed that although the risk of extinction faced by freshwater decapods is quite similar to that of freshwater vertebrates, there is a distinct lack of spatial congruence in geographical range between different taxonomic groups at this spatial scale, and a lack of congruence among three commonly used metrics of biodiversity. The risk of extinction for freshwater species was consistently higher than for their terrestrial counterparts. Main conclusions We demonstrate that broad-scale patterns of species richness, threatened-species richness and endemism lack congruence among the six freshwater taxonomic groups examined. Invertebrate species are seldom taken into account in conservation planning. Our study suggests that both the metric of biodiversity and the identity of the taxa on which conservation decisions are based require careful consideration.As geographical range information becomes available for further sets of species, further testing will be warranted into the extent to which geographical variation in the richness of these six freshwater groups reflects broader patterns of biodiversity in fresh water

Outcomes of COVID-19 related hospitalization among people with HIV in the ISARIC WHO Clinical Characterization Protocol (UK):a prospective observational study

BACKGROUND:Evidence is conflicting about how HIV modulates COVID-19. We compared the presentation characteristics and outcomes of adults with and without HIV who were hospitalized with COVID-19 at 207 centers across the United Kingdom and whose data were prospectively captured by the ISARIC WHO CCP study. METHODS:We used Kaplan-Meier methods and Cox regression to describe the association between HIV status and day-28 mortality, after separate adjustment for sex, ethnicity, age, hospital acquisition of COVID-19 (definite hospital acquisition excluded), presentation date, ten individual comorbidities, and disease severity at presentation (as defined by hypoxia or oxygen therapy). RESULTS:Among 47,592 patients, 122 (0.26%) had confirmed HIV infection and 112/122 (91.8%) had a record of antiretroviral therapy. At presentation, HIV-positive people were younger (median 56 versus 74 years; p<0.001) and had fewer comorbidities, more systemic symptoms and higher lymphocyte counts and C-reactive protein levels. The cumulative day-28 mortality was similar in the HIV-positive vs. HIV-negative groups (26.7% vs. 32.1%; p=0.16), but in those under 60 years of age HIV-positive status was associated with increased mortality (21.3% vs. 9.6%; p<0.001 [log-rank test]). Mortality was higher among people with HIV after adjusting for age (adjusted hazard ratio [aHR] 1.47, 95% confidence interval [CI] 1.01-2.14; p=0.05), and the association persisted after adjusting for the other variables (aHR 1.69; 95% CI 1.15-2.48; p=0.008) and when restricting the analysis to people aged <60 years (aHR 2.87; 95% CI 1.70-4.84; p<0.001). CONCLUSIONS:HIV-positive status was associated with an increased risk of day-28 mortality among patients hospitalized for COVID-19

Linking protein to phenotype with Mendelian Randomization detects 38 proteins with causal roles in human diseases and traits

To efficiently transform genetic associations into drug targets requires evidence that a particular gene, and its encoded protein, contribute causally to a disease. To achieve this, we employ a three-step proteome-by-phenome Mendelian Randomization (MR) approach. In step one, 154 protein quantitative trait loci (pQTLs) were identified and independently replicated. From these pQTLs, 64 replicated locally-acting variants were used as instrumental variables for proteome-by-phenome MR across 846 traits (step two). When its assumptions are met, proteome-by-phenome MR, is equivalent to simultaneously running many randomized controlled trials. Step 2 yielded 38 proteins that significantly predicted variation in traits and diseases in 509 instances. Step 3 revealed that amongst the 271 instances from GeneAtlas (UK Biobank), 77 showed little evidence of pleiotropy (HEIDI), and 92 evidence of colocalization (eCAVIAR). Results were wide ranging: including, for example, new evidence for a causal role of tyrosine-protein phosphatase non-receptor type substrate 1 (SHPS1; SIRPA) in schizophrenia, and a new finding that intestinal fatty acid binding protein (FABP2) abundance contributes to the pathogenesis of cardiovascular disease. We also demonstrated confirmatory evidence for the causal role of four further proteins (FGF5, IL6R, LPL, LTA) in cardiovascular disease risk

Oxygen isotope dendrochronology of Llwyn Celyn; One of the oldest houses in Wales

We report the application of oxygen isotope dendrochronology to date a high-status and remarkably unaltered late medieval hall house on the eastern border of South Wales. The oak timbers have either short and complacent ring series, or very strong growth disturbance, and none were suitable for ring-width dendrochronology. By using stable oxygen isotopes from the latewood cellulose, rather than ring widths, it was possible to cross-match and date all 14 timber samples and to provide felling dates related to several phases of building. The hall and solar cross-wing were constructed shortly after 1420CE, which is remarkably early. The house was upgraded using timbers felled in the winter of 1695/6CE by ceiling over of the hall and inserting a chimney. A separate small domestic building was added at the same time and the addition of the kitchen is likely to be contemporaneous. A substantial beast house was added a few years before the house was refurbished, emphasising the importance of cattle as the main source of wealth. A small barn with timbers felled in spring 1843 CE was added later. Llwyn Celyn is one of the most important domestic buildings in Wales, but without the new approach none of the phases of its evolution could have been dated precisely. Oxygen isotope dendrochronology has enormous potential for dating timbers that have small numbers of rings and/or show severe growth disturbance and it works well in regions where tree growth is not strongly constrained by climate.

Towards nationally curated data archives for clinical radiology image analysis at scale: Learnings from national data collection in response to a pandemic

The prevalence of the coronavirus SARS-CoV-2 disease has resulted in the unprecedented collection of health data to support research. Historically, coordinating the collation of such datasets on a national scale has been challenging to execute for several reasons, including issues with data privacy, the lack of data reporting standards, interoperable technologies, and distribution methods. The coronavirus SARS-CoV-2 disease pandemic has highlighted the importance of collaboration between government bodies, healthcare institutions, academic researchers and commercial companies in overcoming these issues during times of urgency. The National COVID-19 Chest Imaging Database, led by NHSX, British Society of Thoracic Imaging, Royal Surrey NHS Foundation Trust and Faculty, is an example of such a national initiative. Here, we summarise the experiences and challenges of setting up the National COVID-19 Chest Imaging Database, and the implications for future ambitions of national data curation in medical imaging to advance the safe adoption of artificial intelligence in healthcare
