This paper is a preliminary exploration of the connections between the statistical style of reasoning and the research practices of statistical mechanics in the early period of the long quantum revolution. It suggests that before 1925 the instantiations of the statistical style in physics went through two phases. The first phase consisted of the formulation of the Maxwell‐Boltzmann statistics on the basis of the population‐gas analogy. The second phase was characterized by the generalization of the Maxwell‐Boltzmann statistics through analogies between ideal gas molecules and other microphysical entities, analogies that shaped and were shaped by the rise of quantum theory. Einstein's invention of the Bose‐Einstein statistics started a third phase and created the conditions of possibility for a new classification of microphysical entities according to their different statistics. 相似文献

This article examines the urban development of Moscow from 1992 to 2015, arguing that the city's recent transformation from grey asphalt jungle to a “city comfortable for life” is driven by a process of neoliberal restructuring. In particular, the study finds that a set of multi‐scalar dynamics—namely, the global financial crisis, the rise of a local protest movement, and an intensified rivalry between federal and Muscovite elites—were the key driving forces behind Moscow's current evolution. The work advances a conceptual framework of neoliberal urbanisation that enhances the literature on post‐socialist cities and, more generally, the broader debate on actually existing neoliberalism. 相似文献

Die Bundesrepublik Deutschland gilt für viele L?nder, vor allem für ehemals kommunistisch regierte, als ein Vorbild der modernen
Demokratie. Dieser Vorbildcharakter drückte sich auch in den hohen Wahlbeteiligungen aus, mit denen die Bundesrepublik weltweit
einen Spitzenplatz einnahm. Doch seitdem die W?hlerzahlen in den vergangenen fünfzehn Jahren teilweise drastisch zurückgegangen
sind, wird die Wahlbeteiligung aufmerksam beobachtet. Oftmals finden sich nach Wahlen interessante Begründungen für die geringe
Wahlbeteiligung: Bei der nordrhein-westf?lischen Kommunalwahl am 12. September 1999, die an einem Tag mit Sonnenschein und
Temperaturen über 30 Grad stattfand, lag die Wahlbeteiligung bei nur 54 Prozent. Natürlich war das hei?e Badewetter für viele
Politiker schuld daran, da? es eine so geringe, bisher ungekannt schlechte Wahlbeteiligung gab. ?hnlich auch die ?u?erungen
nach einer „hei?en Kommunalwahl“ im Frühjahr 1992 in Berlin, die der Regierende Bürgermeister mit den Worten kommentierte:
„Wir haben eins auf die Bademütze bekommen“ (vgl. Berliner Zeitung, 28.5.1992). 相似文献

Universities' potential to contribute to regional value creation has been extensively discussed so far and significant literature has been devoted to celebrated cases in highly industrialized and developed countries. Assuming that it would be misleading to generalize from “exceptional” cases, some authors have focused their attention specifically on the influence of universities in less developed areas regions and countries, where university–industry relations are far from being a Triple Helix. This paper focuses on the mechanisms of university–industry knowledge transfer (KT) in Romania, a post-communist country with relatively weak regional innovation performances, except for the capital region Bucharest-Ilfov. The purpose of the study is to construct an index to compare university–industry KT across the eight Romanian regions. Data to be aggregated are collected from 90 Romanian higher education institutions and refer to their KT potential in terms of human, financial and relational inputs, outputs and outcomes (patent applications, new products and services, spin-offs and commercial income). Finally, universities' regional KT performances are compared to small and medium enterprises territorial patterns and issuing policy implications are discussed. 相似文献

There is not only one methodology for the study of mineralogical phases in archaeological samples. In this paper, we discuss a strategy applied to ancient iron nail samples completely based on non-destructive analyses. The archaeological samples come from the archaeological site of Valle delle Forme (province of Brescia–Italy) and date back to the 1300–1400 ad. Neutron-based techniques, like time-of-flight neutron diffraction and neutron tomography, have been used to determine the mineralogical composition and the structure of nails. An independent check for the assessment of the presence of different mineralogical phases was given by Raman spectroscopy. The combination of different non-destructive techniques has provided very useful information on their chemical composition, nature of the patina and corrosion features of the nails (also in the bulk of the samples). 相似文献

This study shows the results of a multidisciplinary collaboration between the University of Calabria (Italy) and the National Autonomous University of Mexico (UNAM), about the compositional characterization of some mortars taken from Hagia Sophia in Istanbul (Turkey), one of the most important buildings in antiquity. Twenty samples of joint mortars were analysed by micro-chemical analyses (SEM-EDS), X-ray powder diffraction (XRPD), optical microscopy (OM) and transmission electron microscopy (TEM). The compositional study allowed us to define, with more detail, the construction phases of the fifth, sixth and tenth century. The petrographic analysis in thin section by optical microscopy showed four typologies of sands, used as aggregate, with specific compositional features. SEM-EDS analyses and TEM observations of the binder around the ceramic fragments of the aggregate showed the presence of different morphologies of single C-S-H compounds. 相似文献

A simplified approach for analyzing the nonlinear response of masonry buildings, based on the equivalent frame modeling procedure and on the nonlinear equivalent static analyses, is presented. A nonlinear beam finite element (FE) is formulated in the framework of a force-based approach, where the stress fields are expanded along the beam local axis, and introduced in a global displacement-based FE code. In order to model the nonlinear constitutive response of the masonry material, the lumped hinge approach is adopted and both flexural and shear plastic hinges are located at the two end nodes of the beam. A classical elastic-plastic constitutive relationship describes the nonlinear response of the hinges, the evolution of the plastic variables being governed by the Kuhn-Tucker and consistency conditions. An efficient element state determination procedure is implemented, which condenses the local deformation residual into the global residual vector, thus avoiding the need to perform the inner loops for computing the element nonlinear response. The comparison with some relevant experimental and real full-scale masonry walls is presented, obtaining a very good agreement with the available results, both in terms of global pushover curves and damage distributions. 相似文献
