    From Right to Good, and to Asset: the State-led Financialisation of the Social Rented Housing in Italy

    Rental housing has been regarded as the new ‘frontier for financialisation’ since the 2007 financial crisis. But research examining financialisation of de-commodified rental housing is limited and is primarily focused on stock acquisitions by financial investors and the enabling role of either national or local governments. This critically overlooks the emergence of the financialised production of social rented housing, the interplay between levels of government (particularly with the regional level), and the leading role of the state in these processes. By combining a political sociology approach to policy instruments with a housing system studies perspective, the paper investigates how Italy, through the interplay between national, regional (Lombardy) and local (Milan) governments, led the financialisation of its social rented housing production. Through analyses of six decades of financial-legislative changes in the housing system regarding production/provision, finance and land supply, it identifies a three-stage journey towards financialisation: (1) the rise and fall of publicly-owned rental social housing (1950s to 1990s); (2) the regionalisation and marketisation of the sector up to the late 2000s; and (3) the upward transfer from the first local-scale experiment with the real estate mutual investment fund in Milan to the creation of a national-scale System of Funds for the production of social rented housing. The study shows that the re-commodification of housing and land initiated in the 1980s were intertwined and a conditio-sine-qua-non for financialisation; that the state played a crafting—rather than solely enabling—role in this process; and that trans-scalar legislative–financial innovations transformed social rented housing into a liquid asset class

    An efficient all-optical switch using a lambda atom in a cavity QED system

    We propose an all-optical switch constructed from a two-mode optical resonator containing a strongly coupled, three-state system. The coupling allows a weak, continuous wave laser drive to incoherently control the transmission of a much stronger, continuous wave signal laser into (and through) the resonator. We demonstrate that in this simple setup the presence of a control drive with one tenth the power of the signal drive can induce near complete reflection of the signal, while its absence allows for near complete transmission. The switch can also be operated as a set-reset relay with two control inputs that efficiently drive the switch into either the reflecting or the transmitting state.Comment: 9 pages, 10 figures, v2: published versio

    Not All Children with Under-Control Asthma are Controlled

    Subclinical lung function alterations can sometimes be discovered in asthmatic patients under clinical control. This study aimed to identify the burden of asthmatic children with subclinical airways abnormalities who may benefit from an adjustment in asthma therapy. 134 6-to-17-year-old asthmatic children were enrolled. Of them, 98 presented apparently under clinical control disease and all performed spirometry before and after bronchodilation: 17 (17.3%) had a positive bronchodilation test, in addition to significantly lower lung function indexes as compared to those with under-control asthma who had a negative bronchodilation test. These patients were randomized and re-evaluated: patients (n=8) receiving an adjustment in their therapy showed an improvement in lung function tests and quality of life indexes as compared to 7 without therapy adjustment. In conclusion, a substantial number of apparently-under-control asthmatic children show airways alterations that can be improved by adjusting their therapy, which also seems to enhance their quality of life

    A Lithium Experiment in the Program of Solar Neutrino Research

    The experiments sensitive to pp-neutrinos from the Sun are very perspective for the precise measurement of a mixing angle Ξ12\theta_{12}. A Îœ\nu e−^{-} scattering experiment (Xmass) and/or a charged-current experiment (the indium detector) can measure the flux of electron pp-neutrinos. One can find the total flux of pp-neutrinos from a luminosity constraint after the contribution of 7^7Be and CNO neutrinos to the total luminosity of the Sun are measured. The radiochemical experiment utilizing a lithium target has the high sensitivity to the CNO neutrinos, thus, it has a good promise for the precise measurement of a mixing angle and for the test of a current theory of the evolution of the stars.Comment: 6 pages, 2 figures, 1 table, A report made by A.Kopylov at International Conference NANP-2005, June 2005, Dubna, Russi

    Provisioning virtual private networks under traffic uncertainty

    Get PDF
    We investigate a network design problem under traffic uncertainty that arises when provisioning Virtual Private Networks (VPNs): given a set of terminals that must communicate with one another, and a set of possible traffic matrices, sufficient capacity has to be reserved on the links of the large underlying public network to support all possible traffic matrices while minimizing the total reservation cost. The problem admits several versions depending on the desired topology of the reserved links, and the nature of the traffic data uncertainty. We present compact linear mixed-integer programming formulations for the problem with the classical hose traffic model and for a less conservative robust variant relying on the traffic statistics that are often available. These flow-based formulations allow us to solve optimally medium-to-large instances with commercial MIP solvers. We also propose a combined branch-and-price and cutting-plane algorithm to tackle larger instances. Computational results obtained for several classes of instances are reported and discussed. © 2006 Wiley Periodicals, Inc

    The use of cosmic muons in detecting heterogeneities in large volumes

    Full text link
    The muon intensity attenuation method to detect heterogeneities in large matter volumes is analyzed. Approximate analytical expressions to estimate the collection time and the signal to noise ratio, are proposed and validated by Monte Carlo simulations. Important parameters, including point spread function and coordinate reconstruction uncertainty are also estimated using Monte Carlo simulations.Comment: 8 pages, 11 figures, submetted to NIM
