Smeared heat-kernel coefficients on the ball and generalized cone

We consider smeared zeta functions and heat-kernel coefficients on the bounded, generalized cone in arbitrary dimensions. The specific case of a ball is analysed in detail and used to restrict the form of the heat-kernel coefficients $A_n$ on smooth manifolds with boundary. Supplemented by conformal transformation techniques, it is used to provide an effective scheme for the calculation of the $A_n$. As an application, the complete $A_{5/2}$ coefficient is given.Comment: 23 pages, JyTe

Health informatics education for clinicians and managers - What's holding up progress?

This paper reports outcomes of a national survey of health informatics (HI) education and training carried out in the UK. A questionnaire to elicit details of HI and IT skills teaching was derived from a national consensus document (Learning to Manage Health Information, LtMHI). Forms were sent to all pre-qualification medical and nursing schools and to a stratified sample of postgraduate and post-registration programmes. Three case studies were carried out in acute hospital trusts to gain insight into opportunities for continuing professional development in health informatics and IT. Our evidence suggests that in the UK, health informatics is not yet integrated into the clinical curriculum. Nearly all the pre-qualification courses made some provision for teaching IT skills. Nonetheless, many respondents felt that students did not receive sufficient training. There was considerable variation in the amount of HI teaching provided in the different educational sectors. The case studies suggested very little HI training was provided for clinical staff and take-up of provision was not monitored. A number of factors are holding up progress, the most important being a lack of staff with the knowledge and skills to provide academic leadership. The paper outlines some steps that need to be taken to ensure health informatics is embedded in all clinical curricula. © 2003 Elsevier Ireland Ltd. All rights reserved

Provincial Families of the Renaissance

Grubb's comprehensive analysis of his subjects' compelling, if inconspicuous, lives investigates every significant aspect of private experience during the Renaissance: marriage, birth, death, household relations, work, land, social status, and spirituality. Winner of the Society for Italian Historical Studies's Howard R. Marraro PrizeOriginally published in 1996. Historical writing on the Renaissance has usually focused on the social extremes that co-existed in the great metropolitan centers—on either elites or the underclass. As a result, the world of the middling families and provincial societies remains largely unexplored. Daily experiences in the lesser cities are, however, no less rich and revealing than those of Florence, Venice, and Milan. In addition, writes historian James Grubb, these experiences offer new perspectives from which to reassess familiar assumptions about domestic life in the fifteenth century. Based on memoirs and other records left by thirteen merchant families from the Veneto cities of Verona and Vincenza, Provincial Families of the Renaissance is an engrossing study of daily lives that have until now been overlooked by scholars. Grubb examines the attitudes and experiences of families undistinguished in their modest means and local ambitions from the majority of their compatriots, uncovering a detailed historical landscape rich in social obligations, commercial activities, and religious beliefs.Grubb's comprehensive analysis of his subjects' compelling, if inconspicuous, lives investigates every significant aspect of private experience during the Renaissance: marriage, birth, death, household relations, work, land, social status, and spirituality. In reconstructing provincial life in the Veneto, Grubb discovers in his subjects an independence of mind that mediated their reception of metropolitan ideologies far more than the historiography of the Renaissance might suggest. These "unremarkable" provincials were agents of their own destiny, influenced in equal measures by prevailing attitudes, local customs, and personal convictions. "James Grubb is exploring new terrain in this book. Distinguished by its clarity and eloquence, this is a superior work of historical writing and analysis that merits comparison with the best monographs on the social history of Renaissance Italy."—Gene Brucker, University of California at Berkele

Firstborn of Venice

Selected by Choice Magazine as an Outstanding Academic TitleOriginally published in 1988. In the decades after 1404, traditionally maritime Venice extended its control over much of northern Italy. Citizens of Vicenza, the first city to come under Venetian rule, proclaimed their city "firstborn of Venice" and a model for the Venetian Republic's dominions on the terraferma. In Firstborn of Venice James Grubb tests commonplace attributes of the Renaissance state through a rich case study of society and politics in fifteenth-century Vicenza. Looking at relations between Venetian and local governments and at the location of power in Vicentine society, Grubb reveals the structural limitations of Venetian authority and the mechanisms by which local patricians deflected the claims of the capital. Firstborn of Venice explores issues that are political in the broadest sense: legal institutions and administrative practices, fiscal politics, the consolidation of elites, ecclesiastical management, and the contrasting governing ideologies of ruler and subjects

The Psychological Underpinnings of the Consumer Role in Energy Demand and Carbon Abatement

While policy targeting carbon mitigation has become a priority, the consumer has been sidelined. Within the EU standards and a carbon is price at the industrial level dominate mitigation efforts. There is little room for consumer preferences. Labels on some products do draw a demand for efficient goods, though the messages relayed vary, and the role of embedded emissions often ignored. Once purchased, the energy requirements of various goods and their energy settings are poorly understood by many. In this paper we suggest with appropriately structured policy, providing information and a nudge, that consumers have a willingness and potential to significantly reduce carbon emissions

Realizations of Differential Operators on Conic Manifolds with Boundary

We study the closed extensions (realizations) of differential operators subject to homogeneous boundary conditions on weighted L_p-Sobolev spaces over a manifold with boundary and conical singularities. Under natural ellipticity conditions we determine the domains of the minimal and the maximal extension. We show that both are Fredholm operators and give a formula for the relative index.Comment: 41 pages, 1 figur

Fractional-order operators: Boundary problems, heat equations

The first half of this work gives a survey of the fractional Laplacian (and related operators), its restricted Dirichlet realization on a bounded domain, and its nonhomogeneous local boundary conditions, as treated by pseudodifferential methods. The second half takes up the associated heat equation with homogeneous Dirichlet condition. Here we recall recently shown sharp results on interior regularity and on $L_p$-estimates up to the boundary, as well as recent H\"older estimates. This is supplied with new higher regularity estimates in $L_2$-spaces using a technique of Lions and Magenes, and higher $L_p$-regularity estimates (with arbitrarily high H\"older estimates in the time-parameter) based on a general result of Amann. Moreover, it is shown that an improvement to spatial $C^\infty$-regularity at the boundary is not in general possible.Comment: 29 pages, updated version, to appear in a Springer Proceedings in Mathematics and Statistics: "New Perspectives in Mathematical Analysis - Plenary Lectures, ISAAC 2017, Vaxjo Sweden

Future monitoring of charged particle energy deposition into the upper atmosphere and comments on possible relationships between atmospheric phenomena and solar and/or geomagnetic activity

Monitoring of earth's atmosphere was conducted for several years utilizing the ITOS series of low-altitude, polar-orbiting weather satellites. A space environment monitoring package was included in these satellites to perform measurements of a portion of earth's charged particle environment. The charged particle observations proposed for the low-altitude weather satellite TIROS N, are described which will provide the capability of routine monitoring of the instantaneous total energy deposition into the upper atmosphere by the precipitation of charged particles from higher altitudes. Such observations may be of use in future studies of the relationships between geomagnetic activity and atmospheric weather pattern developments. Estimates are given to assess the potential importance of this type of energy deposition. Discussion and examples are presented illustrating the importance of distinguishing between solar and geomagnetic activity as possible causative sources. Such differentiation is necessary because of the widely different spatial and time scales involved in the atmospheric energy input resulting from these various sources of activity

Differentiation and dynamics of competitiveness impacts from the EU ETS

We summarises the main factors that differentiate impacts of the EU ETS on profitability and market share. By examining sampling a range of sectors, we present some simple metrics and indicators to help judge the nature of potential impacts. We also consider briefly the mitigation response to these impacts by sectors, and how they may evolve over time. The broad conclusion confirms the aggregate findings presented in the existing literature - most participating sectors are likely to profit under the current ETS structure out to 2012 at the cost of a modest loss of market share, but this may not hold for individual companies and regions. The period 2008-12 can assist participating sectors to build experience and financial reserves for longer term technology investments and diversification, providing the continuation and basic principles of the EU ETS post-2012 is quickly defined and incentives are in place for sectors to pursue this.Emissions trading, industrial competitiveness, spillovers, allowance allocation, perverse incentives.

Misplaced expectations from climate disclosure initiatives

The financial sector’s response to pressures around climate change has emphasized the role of disclosure, notably through the recommendations of the Financial Stability Board’s Task Force on Climate-related Financial Disclosures. This Perspective examines two dimensions of the expectations behind transparency and disclosure initiatives: the belief that disinvestment is driven by disclosure; and that investment ‘switches’ from high- to low-carbon assets. We warn about the risk of disappointment from inflated expectations about what transparency can really deliver and suggest some areas that research and public policy should examine to mobilize the required capital to meet climate goals
