Embedding mental wellbeing in Australian regional universities: Equity interventions

Student wellbeing is an important issue to address because research shows that a high percentage of Australian university students experience mental health problems and that higher numbers are found in equity groups. Research also shows that regional universities have a higher percentage of students from equity groups. This paper outlines findings from a study of regional university students and mental health interventions that combined a desktop survey of web-based university resources and an integrative review of relevant literature. Our findings show that most Australian universities do not integrate their mental wellbeing support into the curriculum and that mental health professionals and educators typically work in silos. Consequently, universities only have limited success in addressing student wellbeing needs. We argue that there is a need to draw on best practice for embedding academic support as part of inclusive pedagogies and curricula, in order to extend these to include mental wellbeing support. This study is significant as it is the first to synthesise the key principles of effective embedded wellbeing support in relation to regional university contexts

Literature circles enhancing cultural awareness and language ‎acquisition for adult learners of Arabic

Language and culture are inextricably linked. Consequently, the teaching of cultural awareness as part of additional language instruction is crucial to increasing language proficiency. This paper examines how literature circles are utilized and actively modelled in the teaching and learning of the Arabic language and its culture in an adult Arabic as an Additional Language classroom in Iraq with beginner, intermediate and advanced learners. The impact of the literature circles pedagogy is explored through the analysis of audio transcripts of the interactions during the class, student journals reflections on their experiences participating in the study, and the researcher’s field notes recording their observations during the literature circle activities. Eight participants from diverse cultural and linguistic backgrounds were divided into two multi-level groups. The data revealed that the literature circle methodology increased student-to-student interaction and collaborative learning and understanding of Arabic culture. These outcomes resulted in enhanced confidence in using the language and, consequently language proficiency in the Arabic language

Framing scholars’ perspectives of practices to address breaches of academic integrity in the Muslim world

Although previous work explained internal and external cultural challenges impacting academic integrity in the Muslim world, to date, no study has specifically examined the attempts and practices by the universities to address these challenges. The objective of this paper was to understand the actions taken by academics and institutions in the Muslim world to address, prevent breaches of academic integrity, and to recommend improvement of these practices. To capture institutional efforts and practices, relevant literature from 2010 to 2021 was reviewed to gather evidence of practices of academic integrity in higher education in the Muslim world. The findings suggest a framework that can be used for evaluation of current practices of academic integrity in the Muslim world, to go beyond plagiarism-focussed prevention, detection, and punishments

Characterization of a dense aperture array for radio astronomy

EMBRACE@Nancay is a prototype instrument consisting of an array of 4608 densely packed antenna elements creating a fully sampled, unblocked aperture. This technology is proposed for the Square Kilometre Array and has the potential of providing an extremely large field of view making it the ideal survey instrument. We describe the system,calibration procedures, and results from the prototype.Comment: 17 pages, accepted for publication in A&

806-1 Left Ventricular Ejection Fraction After Myocardial Infarction: Importance of Both Infarct Site and Size

Left ventricular ejection fraction (LVEF) is an important prognostic variable after myocardial infarction (MI). While the extent of MI is known to affect the subsequent global LVEF, it is not clear whether anatomical site per se affects LVEF. Therefore, 48 consecutive patients (pts) who did not receive lytic therapy or undergo early revascularization were studied byechocardiography one week after Q wave MI. Using a previously validated endocardial mapping technique, the size of abnormal wall motion (AWM) in relation to the total endocardial surface area and the site of AWM were quantitated, LVEF was measured by Simpson's method using 2 apical views.ResultsNineteen pts had anterior MI (ANT) and 29 had inferior MI (INF). The mean LVEF was similar in both groups (ANT 46.9±14.7% vs INF 51.7±9.4%, pNS). The mean %AWM was greater in ANT MI (29.7±14.5) than in INF MI (21.3±13.8) (p=0.05). After accounting for differences in infarct size by multivariate regression analysis, both infarct size (p=0.0001) and infarct site (p=0.007) were significant independent determinants of LVEF. This effect was most pronounced in larger ANT Mis (%AWM>25%) where the LVEF was significantly lower than in smaller Mis. In INF MI, despite a similar range of sizes. increasing %AWM had minimal effect on LVEF.ConclusionIn addition to infarct size, the site of AWM is an important determinant of global LVEF. This observation may reflect site-dependent differences in the biomechanical responses to regional ventricular dysfunction

Distributed Minimum Cut Approximation

We study the problem of computing approximate minimum edge cuts by distributed algorithms. We use a standard synchronous message passing model where in each round, $O(\log n)$ bits can be transmitted over each edge (a.k.a. the CONGEST model). We present a distributed algorithm that, for any weighted graph and any $\epsilon \in (0, 1)$, with high probability finds a cut of size at most $O(\epsilon^{-1}\lambda)$ in $O(D) + \tilde{O}(n^{1/2 + \epsilon})$ rounds, where $\lambda$ is the size of the minimum cut. This algorithm is based on a simple approach for analyzing random edge sampling, which we call the random layering technique. In addition, we also present another distributed algorithm, which is based on a centralized algorithm due to Matula [SODA '93], that with high probability computes a cut of size at most $(2+\epsilon)\lambda$ in $\tilde{O}((D+\sqrt{n})/\epsilon^5)$ rounds for any $\epsilon>0$. The time complexities of both of these algorithms almost match the $\tilde{\Omega}(D + \sqrt{n})$ lower bound of Das Sarma et al. [STOC '11], thus leading to an answer to an open question raised by Elkin [SIGACT-News '04] and Das Sarma et al. [STOC '11]. Furthermore, we also strengthen the lower bound of Das Sarma et al. by extending it to unweighted graphs. We show that the same lower bound also holds for unweighted multigraphs (or equivalently for weighted graphs in which $O(w\log n)$ bits can be transmitted in each round over an edge of weight $w$), even if the diameter is $D=O(\log n)$. For unweighted simple graphs, we show that even for networks of diameter $\tilde{O}(\frac{1}{\lambda}\cdot \sqrt{\frac{n}{\alpha\lambda}})$, finding an $\alpha$-approximate minimum cut in networks of edge connectivity $\lambda$ or computing an $\alpha$-approximation of the edge connectivity requires $\tilde{\Omega}(D + \sqrt{\frac{n}{\alpha\lambda}})$ rounds

Interleukin (IL)–12 and IL-23 Are Key Cytokines for Immunity against Salmonella in Humans

Patients with inherited deficiency of the interleukin (IL)–12/IL-23–interferon (IFN)–g axis show increased susceptibility to invasive disease caused by the intramacrophage pathogens salmonellae and mycobacteria. We analyzed data on 154 patients with such deficiency. Significantly more patients with IL-12/IL-23–component deficiency had a history of salmonella disease than did those with IFN-g–component deficiency. Salmonella disease was typically severe, extraintestinal, and caused by nontyphoidal serovars. These findings strongly suggest that IL-12/IL-23 is a key cytokine for immunity against salmonella in humans and that IL-12/IL-23 mediates this protective effect partly through IFN-g–independent pathways. Investigation of the IL-12/IL-23–IFN-g axis should be considered in patients with invasive salmonella disease

Global embedding of the Kerr black hole event horizon into hyperbolic 3-space

An explicit global and unique isometric embedding into hyperbolic 3-space, H^3, of an axi-symmetric 2-surface with Gaussian curvature bounded below is given. In particular, this allows the embedding into H^3 of surfaces of revolution having negative, but finite, Gaussian curvature at smooth fixed points of the U(1) isometry. As an example, we exhibit the global embedding of the Kerr-Newman event horizon into H^3, for arbitrary values of the angular momentum. For this example, considering a quotient of H^3 by the Picard group, we show that the hyperbolic embedding fits in a fundamental domain of the group up to a slightly larger value of the angular momentum than the limit for which a global embedding into Euclidean 3-space is possible. An embedding of the double-Kerr event horizon is also presented, as an example of an embedding which cannot be made global.Comment: 16 pages, 13 figure
