MOOCs 2.0: Reviewing n.paradoxa's MOOC on Contemporary Art and Feminism

This collaboratively written article explores the pedagogical role of MOOCs today through analysis of a MOOC on contemporary art and feminism, created by Katy Deepwell, editor of the international feminist art journal n.paradoxa. Parme Giuntini offers an updated overview of MOOCs and their increasing value as OERs for faculty and students. Feminist art historians Anne Swartz and Kathleen Wentrack investigate the n.paradoxa MOOC from different, but complimentary perspectives. Wentrack explores the structure, documents, and interactivity of the MOOC as a rich source of feminist material useful to both students and scholars. Swartz addresses Deepwell’s international treatment of transnational feminism at a moment when feminIsm is under worldwide siege

Bridging the Research/Teaching Divide with DAH and SoTL-AH

This paper explores the potential for rigorous pedagogical scholarship to complement developments in digital art history (DAH). In addition to introducing ideas and methods that characterize scholarship of teaching and learning (SOTL) in higher education, we focus on two major themes: how digital tools and techniques can support robust scholarship of teaching and learning in art history (SoTL-AH) and ways that SoTL-AH can be used to evaluate and demonstrate the impact of DAH projects in the classroom and the public realm. Our goal is to encourage greater exchange between these two emerging fields that can together advance art historical study

Early mobilisation in critically ill COVID-19 patients: a subanalysis of the ESICM-initiated UNITE-COVID observational study

Background Early mobilisation (EM) is an intervention that may improve the outcome of critically ill patients. There is limited data on EM in COVID-19 patients and its use during the first pandemic wave. Methods This is a pre-planned subanalysis of the ESICM UNITE-COVID, an international multicenter observational study involving critically ill COVID-19 patients in the ICU between February 15th and May 15th, 2020. We analysed variables associated with the initiation of EM (within 72 h of ICU admission) and explored the impact of EM on mortality, ICU and hospital length of stay, as well as discharge location. Statistical analyses were done using (generalised) linear mixed-effect models and ANOVAs. Results Mobilisation data from 4190 patients from 280 ICUs in 45 countries were analysed. 1114 (26.6%) of these patients received mobilisation within 72 h after ICU admission; 3076 (73.4%) did not. In our analysis of factors associated with EM, mechanical ventilation at admission (OR 0.29; 95% CI 0.25, 0.35; p = 0.001), higher age (OR 0.99; 95% CI 0.98, 1.00; p ≤ 0.001), pre-existing asthma (OR 0.84; 95% CI 0.73, 0.98; p = 0.028), and pre-existing kidney disease (OR 0.84; 95% CI 0.71, 0.99; p = 0.036) were negatively associated with the initiation of EM. EM was associated with a higher chance of being discharged home (OR 1.31; 95% CI 1.08, 1.58; p = 0.007) but was not associated with length of stay in ICU (adj. difference 0.91 days; 95% CI − 0.47, 1.37, p = 0.34) and hospital (adj. difference 1.4 days; 95% CI − 0.62, 2.35, p = 0.24) or mortality (OR 0.88; 95% CI 0.7, 1.09, p = 0.24) when adjusted for covariates. Conclusions Our findings demonstrate that a quarter of COVID-19 patients received EM. There was no association found between EM in COVID-19 patients' ICU and hospital length of stay or mortality. However, EM in COVID-19 patients was associated with increased odds of being discharged home rather than to a care facility.

Proper Orthogonal Decomposition of Reynolds and Dispersive Stresses in Turbulent Boundary Layers Over Multi-Scale Rough Patches

\u3eMulti-scale rough patches are present in topologies such as urban canopies (cities) and natural landscapes (forests, ocean floors). The flow over such canopies is three-dimensional, with turbulent structures known as secondary flows present in the boundary layer due to the difference in rough surface heterogeneities. Three dimensional instantaneous velocities are analyzed within the roughness sublayer over three generations of multi-scale rough patches at nine vertical planes using particle image velocimetry obtained experimentally. The secondary structures present in the flow are identified in the form of Reynolds and dispersive fluctuations. Proper orthogonal decomposition is employed to characterize the imprint of the flow. The energy contained within the flow structures is represented through the modes, with the first few modes being the dominant modes and containing the most turbulent kinetic energy. Using these modes, corresponding Reynolds and dispersive stresses are reconstructed thus filtering the flow domains and demonstrating the coherence of both the Reynolds and dispersive stresses for the generations. The dispersive stresses can be reconstructed with fewer modes than the Reynolds stresses, and are approximately an order of magnitude smaller. The reconstructed domains are used to compute the wall shear stress through the integrated momentum equation and related to the flow coherence. The contribution of dispersive stresses to the wall shear stress is small due to the dispersive stresses being concentrated at the wall, while that of Reynolds stress is significant. This affects the low-order calculation of the wall shear stress for each generation. The rough surface generations with the highest Reynolds numbers associated with the momentum thickness also have the highest wall shear stress, but all experience similar trends in the amount of modes required to reach full representation
