Shape
2020
In geometry, shape is the object of theorems associated to a class of transformations. It corresponds to the invariant properties of regions, figures, solids, which are not altered by transformations. The concept of shape implies the concepts of space, upon which transformations are acted, and metric, if distance is preserved, or a measurement function. The invariant properties of shape are fundamental to perception too. However, the classes of transformations build a hierarchy along which shape is more and more abstract from the Euclidean to the topological group, and accordingly, a greater number of perceptual properties are being lost. The science of perception addresses also the questio…
Search for light scalar top quark pair production in final states with two leptons with the ATLAS detector in sqrt(s) = 7 TeV proton-proton collisions
2012
A search is presented for the pair production of light scalar top quarks in s√=7 TeV proton–proton collisions recorded with the ATLAS detector at the Large Hadron Collider. This analysis uses the full data sample collected during 2011 running that corresponds to a total integrated luminosity of 4.7 fb[superscript −1]. Light scalar top quarks are searched for in events with two opposite-sign leptons (e, μ), large missing transverse momentum and at least one jet in the final state. No excess over Standard Model expectations is found, and the results are interpreted under the assumption that the light scalar top decays to a b-quark in addition to an on-shell chargino whose decay occurs through…
Supply and uses of wood in Auvergne, from the Iron Age in the Middle Ages
2018
Waterlogged woods are rare discoveries in archeology because of the conditions inherent in their conservation. When they reach us, they give a lot of data on the importance of this material for past populations.Auvergne is a privileged context for their conservation. Thousands of woods from fortuitous discoveries or archaeological excavations are dated from the Neolithic to the modern era, however the corpus covers mostly the Second Iron Age until the Middle Ages.The diversity of the woods enables a better understanding of different uses according to their respective destination.The state of conservation of many elements gives information about the different stages of shaping, from the fell…
Reaching for different ends through tenure track—institutional logics in university career systems
2020
AbstractIn this study, we used the institutional logics perspective to identify the logics underpinning the tenure track career system, how the logics manifest themselves in recruitment and performance management and how academic leaders and academics negotiate between the logics. The study contributes to research on governance dynamics in academia and to universities’ organisational transformation in the context of strategic actorhood. The data comprised interviews with academic leaders (vice-rectors, deans, department heads) and academics in tenure track positions at two Finnish universities. Empirically, the study explores two key areas of human resource management: recruitment and perfo…

Relations between multi-resolution analysis and quantum mechanics
2005
We discuss a procedure to construct multiresolution analyses (MRA) of L2 (R) starting from a given seed function h (s) which should satisfy some conditions. Our method, originally related to the quantum mechanical Hamiltonian of the fractional quantum Hall effect, is shown to be model independent. The role of a canonical map between certain canonically conjugate operators is discussed. This clarifies our previous procedure and makes much easier most of the original formulas, producing a convenient framework to produce examples of MRA. © 2005 American Institute of Physics.
La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo
2023
Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

Transformations socio-spatiales de Besançon : analyse exploratoire multi-dates
2009
This article proposes an analysis of socio-spatial configurations of various districts in the city of Besançon over the intercensal period from 1990 to 1999. This study is based on a multi-date exploratory statistical analysis trying to clarify the sustainable or unsustainable structures in the urban system. Census data for 1990 and 1999 are used to generate twenty or so indicators which characterize the enumeration districts of Besançon (these statistical areas are known as IRIS in French census). According to a factor analysis, we can observe the trajectories of the IRIS between the two chosen dates, which depend on the considered indicators. This analysis highlights the sociospatial orga…
