New Perspectives on Mathematics Pedagogy

“New Perspectives on Mathematics Pedagogy” represents a serious attempt to understand pedagogy within mathematics classrooms. To that end, this symposium will address the key questions and issues surrounding mathematics pedagogy presently confronting vast numbers of researchers, as well as educators, and policy makers. Organised around presentations, responses, discussion and debate, the symposium is intended not only to enhance understanding but also to stimulate fresh thinking and initiate ongoing critical dialogue about the practice of mathematics pedagogy within teaching and learning settings

Cold Nuclear Matter In Holographic QCD

We study the Sakai-Sugimoto model of holographic QCD at zero temperature and finite chemical potential. We find that as the baryon chemical potential is increased above a critical value, there is a phase transition to a nuclear matter phase characterized by a condensate of instantons on the probe D-branes in the string theory dual. As a result of electrostatic interactions between the instantons, this condensate expands towards the UV when the chemical potential is increased, giving a holographic version of the expansion of the Fermi surface. We argue based on properties of instantons that the nuclear matter phase is necessarily inhomogeneous to arbitrarily high density. This suggests an explanation of the "chiral density wave" instability of the quark Fermi surface in large N_c QCD at asymptotically large chemical potential. We study properties of the nuclear matter phase as a function of chemical potential beyond the transition and argue in particular that the model can be used to make a semi-quantitative prediction of the binding energy per nucleon for nuclear matter in ordinary QCD.Comment: 31 pages, LaTeX, 1 figure, v2: some formulae corrected, qualitative results unchange

Random Matrix Theories in Quantum Physics: Common Concepts

We review the development of random-matrix theory (RMT) during the last decade. We emphasize both the theoretical aspects, and the application of the theory to a number of fields. These comprise chaotic and disordered systems, the localization problem, many-body quantum systems, the Calogero-Sutherland model, chiral symmetry breaking in QCD, and quantum gravity in two dimensions. The review is preceded by a brief historical survey of the developments of RMT and of localization theory since their inception. We emphasize the concepts common to the above-mentioned fields as well as the great diversity of RMT. In view of the universality of RMT, we suggest that the current development signals the emergence of a new "statistical mechanics": Stochasticity and general symmetry requirements lead to universal laws not based on dynamical principles.Comment: 178 pages, Revtex, 45 figures, submitted to Physics Report

Consensus Recommendations for the Use of Automated Insulin Delivery (AID) Technologies in Clinical Practice

International audienceThe significant and growing global prevalence of diabetes continues to challenge people with diabetes (PwD), healthcare providers and payers. While maintaining near-normal glucose levels has been shown to prevent or delay the progression of the long-term complications of diabetes, a significant proportion of PwD are not attaining their glycemic goals. During the past six years, we have seen tremendous advances in automated insulin delivery (AID) technologies. Numerous randomized controlled trials and real-world studies have shown that the use of AID systems is safe and effective in helping PwD achieve their long-term glycemic goals while reducing hypoglycemia risk. Thus, AID systems have recently become an integral part of diabetes management. However, recommendations for using AID systems in clinical settings have been lacking. Such guided recommendations are critical for AID success and acceptance. All clinicians working with PwD need to become familiar with the available systems in order to eliminate disparities in diabetes quality of care. This report provides much-needed guidance for clinicians who are interested in utilizing AIDs and presents a comprehensive listing of the evidence payers should consider when determining eligibility criteria for AID insurance coverage

Colonial lives of the carceral archipelago: rethinking the neoliberal security state

Mass incarceration, police brutality, and border controls are part and parcel of the everyday experiences of marginalized and racialized communities across the world. Recent scholarship in international relations, sociology, and geography has examined the prevalence of these coercive practices through the prism of “disciplinary,” “penal,” or “authoritarian” neoliberalism. In this collective discussion, we argue that although this literature has brought to the fore neoliberalism's reliance on state violence, it has yet to interrogate how these carceral measures are linked to previous forms of global racial ordering. To rectify this moment of “colonial unknowing,” the collective discussion draws on decolonial approaches, Indigenous studies, and theories of racial capitalism. It demonstrates that “new” and “neoliberal” forms of domestic control must be situated within the global longue durée of racialized and colonial accumulation by dispossession. By mapping contemporary modes of policing, incarceration, migration control, and surveillance onto earlier forms of racial–colonial subjugation, we argue that countering the violence of neoliberalism requires more than nostalgic appeals for a return to Keynesianism. What is needed is abolition—not just of the carceral archipelago, but of the very system of racial capitalism that produces and depends on these global vectors of organized violence and abandonment. L'incarcération de masse, la brutalité policière et les contrôles aux frontières constituent une partie intégrante des expériences quotidiennes des communautés marginalisées et racialisées du monde entier. Des études récentes en relations internationales, en sociologie et en géographie ont examiné la prévalence de ces pratiques coercitives par le prisme du néolibéralisme « disciplinaire », « pénal » ou « autoritaire ». Dans cet article, nous soutenons que bien que cette littérature ait mis en évidence la dépendance du néolibéralisme à la violence étatique, elle ne s'est pas encore interrogée sur le lien entre ces mesures carcérales et les formes précédentes d'ordre racial mondial. Cet article s'appuie sur le féminisme noir, les approches décoloniales, les études indigènes et les théories de capitalisme racial pour rectifier cette « ignorance coloniale » marquante. Il démontre que les formes « nouvelles » et « néolibérales » de contrôle national doivent se situer dans la longue durée globale de l'accumulation racialisée et coloniale par dépossession. Nous associons les modes contemporains de maintien de l'ordre, d'incarcération, de contrôle migratoire et de surveillance à des formes antérieures d'assujettissement racial/colonial pour soutenir que contrer la violence du néolibéralisme exige davantage que des appels nostalgiques au retour du keynésianisme. Ce qu'il faut, c'est une abolition : non seulement de l'archipel carcéral, mais aussi du système de capitalisme racial en lui-même qui produit et dépend de ces vecteurs globaux de violence organisée et d'abandon. El encarcelamiento masivo, la brutalidad policial y los controles fronterizos forman parte de las experiencias cotidianas de las comunidades marginadas y racializadas de todo el mundo. Estudios recientes en RI, Sociología y Geografía han examinado la prevalencia de estas prácticas coercitivas a través del prisma del neoliberalismo “disciplinario,” “penal” o “autoritario.” En este artículo, sostenemos que, si bien esta literatura puso en primer plano la dependencia del neoliberalismo de la violencia estatal, aún tiene que cuestionar la manera en que estas medidas carcelarias se vinculan a formas anteriores de ordenamiento racial global. Para rectificar este momento de “desconocimiento colonial,” el artículo recurre al feminismo negro, a los abordajes descoloniales, a los estudios indígenas y a las teorías del capitalismo racial. Demuestra que las formas “nuevas” y “neoliberales” de control interno se deben situar dentro de la longue durée global de la acumulación por desposesión racializada y colonial. Al trazar un mapa de los modos contemporáneos de vigilancia policial, encarcelamiento, control de la migración y vigilancia sobre las formas anteriores de subyugación racial-colonial, sostenemos que contrarrestar la violencia del neoliberalismo requiere algo más que apelaciones nostálgicas de retorno al keynesianismo. Lo que se necesita es la abolición, no solo del archipiélago carcelario, sino también del propio sistema de capitalismo racial que produce y depende de estos vectores globales de violencia y abandono organizados

Half a century of amyloids: past, present and future

Amyloid diseases are global epidemics with profound health, social and economic implications and yet remain without a cure. This dire situation calls for research into the origin and pathological manifestations of amyloidosis to stimulate continued development of new therapeutics. In basic science and engineering, the cross-ß architecture has been a constant thread underlying the structural characteristics of pathological and functional amyloids, and realizing that amyloid structures can be both pathological and functional in nature has fuelled innovations in artificial amyloids, whose use today ranges from water purification to 3D printing. At the conclusion of a half century since Eanes and Glenner's seminal study of amyloids in humans, this review commemorates the occasion by documenting the major milestones in amyloid research to date, from the perspectives of structural biology, biophysics, medicine, microbiology, engineering and nanotechnology. We also discuss new challenges and opportunities to drive this interdisciplinary field moving forward. This journal i
