Does Small Dam Removal Affect Local Property Values? An Empirical Analysis

This paper uses hedonic analysis to examine the impact of small dam removal on property values in South-central Wiscosin. Data on residential property sales were obtained for three categories of sites: those where a dam is intact, those where a dam was recently removed, and those where the stream has been free-flowing for at least 20 years. The primary conclusions that emerge from the data are that residential property located in the vicinity of a free-flowing stream is more valuable than identical property in the vicinity of a small impoundment, and that shoreline frontage along small impoundments confers no increase in residential property value compared to frontage along free-flowing streams.

e-Leadership in Academia: A New Form of Leadership Emerging from Networks of Interdisciplinary Research

High-power impulse magnetron sputtering (HiPIMS) is a promising sputtering-based ionized physical vapor deposition technique and is already making its way to industrial applications. The major difference between HiPIMS and conventional magnetron sputtering processes is the mode of operation. In HiPIMS the power is applied to the magnetron (target) in unipolar pulses at a low duty factor (andlt;10%) and low frequency (andlt;10 kHz) leading to peak target power densities of the order of several kilowatts per square centimeter while keeping the average target power density low enough to avoid magnetron overheating and target melting. These conditions result in the generation of a highly dense plasma discharge, where a large fraction of the sputtered material is ionized and thereby providing new and added means for the synthesis of tailor-made thin films. In this review, the features distinguishing HiPIMS from other deposition methods will be addressed in detail along with how they influence the deposition conditions, such as the plasma parameters and the sputtered material, as well as the resulting thin film properties, such as microstructure, phase formation, and chemical composition. General trends will be established in conjunction to industrially relevant material systems to present this emerging technology to the interested reader.Funding Agencies|Swedish Research Council (VR)|623-2009-7348

Le marché et le politique. Le rôle de l'action publique dans le développement de la musique ancienne

En se fondant sur l’étude du rôle du soutien public dans le développement du monde de la musique ancienne, l’article se propose d’avancer des éléments de repérage des dimensions marchandes et politiques de ce soutien public. Contre les représentations indigènes, il montre que le soutien public, instrumenté par des marchés (le marché des subventions et le marché des concerts), a été fondamental dans ce développement en raison de son caractère à la fois systématique et incontrôlé.By studying the role of public support in the development of early music in France, the paper proposes criteria to discuss this support as politics and as implemented by the market. The public authorities are commonly said to play no role in this development : early music actors are supposed to develop only through their own forces, with few subsidies and with no cultural policy in support of them. It is shown that public action has had a much more important role than what is commonly considered, and that their action has passed through a particular mechanism : the market

Manipulation of thin metal film morphology on weakly interacting substrates via selective deployment of alloying species

We demonstrate a versatile concept for manipulating morphology of thin (& LE;25 nm) noble-metal films on weakly interacting substrates using growth of Ag on SiO2 as a model system. The concept entails deployment of minority metallic (Cu, Au, Al, Ti, Cr, and Mo) alloying species at the Ag-layer growth front. Data from in situ and real-time monitoring of the deposition process show that all alloying agents-when deployed together with Ag vapor throughout the entire film deposition-favor two-dimensional (2D) growth morphology as compared to pure Ag film growth. This is manifested by an increase in the substrate area coverage for a given amount of deposited material in discontinuous layers and a decrease of the thickness at which a continuous layer is formed, though at the expense of a larger electrical resistivity. Based on ex situ microstructural analyses, we conclude that 2D morphological evolution under the presence of alloying species is predominantly caused by a decrease of the rate of island coalescence completion during the initial film-formation stages. Guided by this realization, alloying species are released with high temporal precision to selectively target growth stages before and after coalescence completion. Pre-coalescence deployment of all alloying agents yields a more pronounced 2D growth morphology, which for the case of Cu, Al, and Au is achieved without compromising the Ag-layer electrical conductivity. A more complex behavior is observed when alloying atoms are deposited during the post-coalescence growth stages: Cu, Au, Al, and Cr favor 2D morphology, while Ti and Mo yield a more pronounced three-dimensional morphological evolution. The overall results presented herein show that targeted deployment of alloying agents constitutes a generic platform for designing bespoken heterostructures between metal layers and technologically relevant weakly interacting substrates.& nbsp;Published under an exclusive license by the AVS.Peer reviewe
