    Lax forms of the qq-Painlev\'e equations

    Full text link
    All qq-Painlev\'e equations which are obtained from the qq-analog of the sixth Painlev\'e equation are expressed in a Lax formalism. They are characterized by the data of the associated linear qq-difference equations. The degeneration pattern from the qq-Painlev\'e equation of type A2A_2 is also presented.Comment: 24 page

    Tissue eosinophilia and eosinophil degranulation in Riedel's invasive fibrous thyroiditis.

    The etiology of Riedel's invasive fibrous thyroiditis (IFT) has remained obscure. This rare disorder has been confused in the past with the more common fibrous variant of Hashimoto's disease. The typical histological features of IFT, in particular the presence of an invasive fibrosclerotic process in conjunction with a prominent chronic inflammatory infiltrate, suggest that the release of fibrogenic cytokines and other factors from these cellular infiltrates may play an important role in the pathogenesis of this condition. Our observations in routinely processed tissue sections obtained from patients with documented IFT of striking tissue eosinophilia led us to hypothesize that eosinophils and their products may play a role in the evolution of this disease. Immunofluorescence staining with affinity-purified polyclonal rabbit antibody directed against human eosinophil granule major basic protein revealed marked tissue eosinophilia and abundant extracellular deposition of major basic protein in all specimens from 16 patients with IFT. By contrast, only occasional eosinophils and no extracellular major basic protein were detected in control thyroid tissues obtained from patients with multinodular goiter, Graves' disease, Hashimoto's disease, and normal thyroid tissue. The presence of marked eosinophil infiltration and extracellular major basic protein deposition in IFT and other associated fibrosclerotic conditions suggests a role for eosinophils and their products in propagating the fibrogenesis seen in IFT

    Restoring Trust in Finance: From Principal–Agent to Principled Agent

    Full text link
    © 2019 Economic Society of Australia Banking solves the principal–agent problem with incentive contracts which assume a Homo Economicus representative agent. However, professions can solve the principal–agent problem by assuming a ‘Reasonable Person’ representative agent, from tort law, who reliably tells the truth about hidden action. We describe a non-virtuous circle in finance, which is a negative feedback loop between motivation crowding out arising from incentive contracts, and the subsequent need to offer incentive contacts because agents change from the Reasonable Person to Homo Economicus. We prescribe less reliance on incentive contracts in the practice of finance, and on Homo Economicus in the theory of finance

    Blind spots in IPE : marginalized perspectives and neglected trends in contemporary capitalism

    Get PDF
    Which blind spots shape scholarship in International Political Economy (IPE)? That question animates the contributions to a double special issue—one in the Review of International Political Economy, and a companion one in New Political Economy. The global financial crisis had seemed to vindicate broad-ranging IPE perspectives at the expense of narrow economics theories. Yet the tumultuous decade since then has confronted IPE scholars with rapidly-shifting global dynamics, many of which had remained underappreciated. We use the Blind Spots moniker in an attempt to push the topics covered here higher up the scholarly agenda—issues that range from institutionalized racism and misogyny to the rise of big tech, intensifying corporate power, expertise-dynamics in global governance, assetization, and climate change. Gendered and racial inequalities as blind spots have a particular charge. There has been a self-reinforcing correspondence between topics that have counted as important, people to whom they matter personally, and the latter’s ability to build careers on them. In that sense, our mission is not only to highlight collective blind spots that may dull IPE’s capacity to theorize the current moment. It is also a normative one—a form of disciplinary housekeeping to help correct both intellectual and professional entrenched biases

    Regional agriculture surveys using ERTS-1 data

    Get PDF
    The Center for Remote Sensing Research has conducted studies designed to evaluate the potential application of ERTS data in performing agricultural inventories, and to develop efficient methods of data handling and analysis useful in the operational context for performing large area surveys. This work has resulted in the development of an integrated system utilizing both human and computer analysis of ground, aerial, and space imagery, which has been shown to be very efficient for regional crop acreage inventories. The technique involves: (1) the delineation of ERTS images into relatively homogeneous strata by human interpreters, (2) the point-by-point classification of the area within each strata on the basis of crop type using a human/machine interactive digital image processing system; and (3) a multistage sampling procedure for the collection of supporting aerial and ground data used in the adjustment and verification of the classification results

    Morphogenetic Theory and the Constructivist Institutionalist Challenge

    Get PDF
    This article engages with two meta-theoretical approaches to social analysis, ‘morphogenetic theory’ and ‘constructivist institutionalism’, and specifically explores how the former fares under the critical scrutiny of the latter. The key proponent of constructivist institutionalism, Colin Hay, has offered two detailed critiques of morphogenesis that criticise its position on the foundational sociological issues of structure-agency and material-ideational. Although Hay’s critiques are largely rejected in an overall defence of the morphogenetic approach, the process of engagement is seen to be particularly useful for morphogenetic theory because it allows a number of important clarifications to be made and it also opens up space for theoretical development. In the course of this debate, accessible introductions are given to both theories, and the similarities and differences between them are outlined, providing clarity to both. Therefore, although this article ultimately operates as a defence of morphogenetic theory, especially in the form proposed by Margaret Archer and Douglas Porpora, it finds a great deal of fruitful discussion in the constructivist institutionalist challenge

    Measured Sensitivity of the First Mark II Phased Array Feed on an ASKAP Antenna

    Full text link
    This paper presents the measured sensitivity of CSIRO's first Mk. II phased array feed (PAF) on an ASKAP antenna. The Mk. II achieves a minimum system-temperature-over-efficiency Tsys/ηT_\mathrm{sys}/\eta of 78 K at 1.23 GHz and is 95 K or better from 835 MHz to 1.8 GHz. This PAF was designed for the Australian SKA Pathfinder telescope to demonstrate fast astronomical surveys with a wide field of view for the Square Kilometre Array (SKA).Comment: 5 pages, 2 figures, accepted for publication in Electromagnetics in Advanced applications (ICEAA), 2015 International Conference o
