Paesaggio sacralizzato e militanza ecclesiale
Full text linkIl contributo focalizza il tema della sacralizzazione del paesaggio nella contemporanità, ponendo la questione in relazione con le dinamiche storico-sociali e politiche del Dopoguerra. Caso-studio è il Getsemani di Casale Corte Cerro, ideato da Luigi Gedda - protagonista della politica italiana degli anni Cinquanta - e realizzato da Ildo Avetta
Service co-production and value co-creation: the case for a service-oriented architecture (SOA)
No full textAn emerging marketing management logic proposes a new perspective on service activities, which previously have been subject to a biased goods-dominant logic.
According to this new logic, customers always are co-producers of services and co-creators of value, not simple marketing targets, because they mobilize knowledge and other resources in the service process that affect the success of a value proposition. This article explores this key proposition, analyzing service co-production and value co-creation phenomena in the business-to-business segment and focusing on the case of service-oriented
architecture (SOA) with an in-depth, qualitative analysis of two firms pioneering the implementation of SOA solutions
Computer simulations of liquid crystals and polymers
No full textLiquid crystals, polymers and polymer liquid crystals are soft condensed matter systems of major technological and scientific interest. An understanding of the macroscopic properties of these complex systems and of their many and interesting peculiarities at the molecular level can nowadays only be attained using computer simulations and statistical mechanical theories. Both in the Liquid Crystal and Polymer fields a considerable amount of simulation work has been done in the last few years with various classes of models at different special resolutions, ranging from atomistic to molecular and coarse-grained lattice models. Each of the two fields has developed its own set of tools and specialized procedures and the book aims to provide a state of the art review of the computer simulation studies of polymers and liquid crystals. This is of great importance in view of a potential cross-fertilization between these connected areas which is particularly apparent for a number of experimental systems like, e.g. polymer liquid crystals and anisotropic gels where the different fields necessarily merge. An effort has been made to assess the possibilities of a coherent description of the themes that have developed independently, and to compare and extend the theoretical and computational techniques put forward in the different areas
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Elastic anisotropy and anchoring effects on the textures of nematic films with random planar surface alignment
No full textWe present aMonte Carlo study of topological defects in nematic films with random planar boundary conditions. The polarized microscopy images and their evolution are analysed in uniaxial systems for different anchoring strengths and film thicknesses
Nematics with dispersed polymer networks: from lattice spin models to experimental observables
No full textWe report our Monte Carlo studies of molecular ordering in nematic liquid crystals with dispersed polymer networks. Starting from the aligning effect of a single fiber, we study different network topographies and investigate regular and random arrays of straight and distorted polymer fibrils. We analyze the aligning ability of rough fibrils, external field-induced switching, and pretransitional ordering. The simulation output is used to calculate selected experimental observables: 2H NMR spectra, capacitance, and intensity of transmitted polarized light
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
