How Debt Markets have Malfunctioned in the Crisis
No full textThis article explains how debt markets have malfunctioned in the crisis, with deleterious consequences for the real economy. I begin with a quick overview of debt markets. I then discuss three areas that are crucial in all debt markets decisions: risk capital and risk aversion, repo financing and haircuts, and counterparty risk. In each of these areas, feedback effects can arise, so that less liquidity and a higher cost for finance can reinforce each other in a contagious spiral. I document the remarkable rise in the premium that investors placed on liquidity during the crisis. Next, I show how these issues caused debt markets to break down: fundamental values and market values seemed to diverge across several markets and products that were far removed from the “toxic” subprime mortgage assets at the root of the crisis. Finally, I discuss briefly four steps that the Federal Reserve took to ease the crisis, and how each was geared to a specific systemic fault that arose during the crisis.

The Lorenz-Krishnamurthy slow manifold
No full textThe authors scale the five-mode model introduced by Lorenz and Krishnamurthy and show how explicit solutions may be obtained in the limit of small Rossby number by using the method of multiple scales. They thus obtain a characterization of the “slow manifold†of this model. Reprinted by permission of the publisher
The Slow Invariant Manifold of the Lorenz–Krishnamurthy Model
No full textInternational audienceDuring this last decades, several attempts to construct slow invariant manifold of the Lorenz-Krishnamurthy five-mode model of slow-fast interactions in the atmosphere have been made by various authors. Unfortunately, as in the case of many two-time scales singularly perturbed dynamical systems the various asymptotic procedures involved for such a construction diverge. So, it seems that till now only the first-order and third-order approximations of this slow manifold have been analytically obtained. While using the Flow Curvature Method we show in this work that one can provide the eighteenth-order approximation of the slow manifold of the generalized Lorenz-Krishnamurthy model and the thirteenth-order approximation of the " conservative " Lorenz-Krishnamurthy model. The invariance of each slow manifold is then established according to Darboux invariance theorem
Meena Krishnamurthy and Political Emotions
No full textWhat are the roles that emotions play in politics and civic life? Do feelings like rage, happiness or tension get in the way of political progress, or are they important tools in the fight for social justice? On this episode of Examining Ethics, Christiane interviews Meena Krishnamurthy, a philosopher whose recent work explores the value of political emotions in Martin Luther King Jr.’s writing and activism
Prevalence of poststroke dysphagia in India (Krishnamurthy et al., 2022)
No full textObjectives: This study aimed to determine the prevalence of reported dysphagia and associated pneumonia risk among patients with stroke in India. Method: We carried out a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary outcome of interest was dysphagia and pneumonia among patients with stroke in India. Two review authors independently assessed the quality of studies using the Newcastle–Ottawa Scale and extracted related data. Meta-analysis was performed for frequency of dysphagia, associated pneumonia, and its relative risk using a random-effects model. Statistical heterogeneity was computed using the I2 index.Results: A total of 3,644 titles were screened, and only eight studies met our inclusion criteria. Based on data from these studies, we calculated the pooled prevalence of dysphagia (47.71%; 95% confidence interval [CI] [20.49%, 70.92%], p p p Conclusions: Despite the high incidence of dysphagia and associated pneumonia, the methodological quality of studies is fair and there is little research focused on epidemiological data. We call to arms to those SLPs working with patients with stroke in India to become proactive in both clinical practice and research domains.Supplemental Material S1.
