POVM Quantization

We present a general formalism for giving a measure space paired with a separable Hilbert space a quantum version based on normalized positive operator-valued measure. The latter are built from families of density operators labelled by points of the measure space. We specially focus on various probabilistic aspects of these constructions. Simple or more elaborate examples illustrate the procedure: circle, 2-sphere, plane, half-plane. Links with POVM quantum measurement and quantum statistical inference are sketched

A unified framework for building ontological theories with application and testing in the field of clinical trials

The objective of this research programme is to contribute to the establishment of the emerging science of Formal Ontology in Information Systems via a collaborative project involving researchers from a range of disciplines including philosophy, logic, computer science, linguistics, and the medical sciences. The re­searchers will work together on the construction of a unified formal ontology, which means: a general framework for the construction of ontological theories in specific domains. The framework will be constructed using the axiomatic-deductive method of modern formal ontology. It will be tested via a series of applications relating to on-going work in Leipzig on medical taxonomies and data dictionaries in the context of clinical trials. This will lead to the production of a domain-specific ontology which is designed to serve as a basis for applications in the medical field

Grain Reynolds number scale effects in dry granular slides

©2020. The Authors. Scale effects are differences in physical behavior that manifest between a large event and a geometrically scaled laboratory model and may cause misleading predictions. This study focuses on scale effects in granular slides, important in the environment and to industry. A versatile 6 m long laboratory setup has been built following Froude similarity to investigate dry granular slides at scales varied by a factor of 4, with grain Reynolds numbers Rein the range of 102 to 103. To provide further comparison, discrete element method simulations have also been conducted. Significant scale effects were identified; the nondimensional surface velocity increased by up to 35%, while the deposit runout distance increased by up to 26% from the smallest to the largest model. These scale effects are strongly correlated with Re, suggesting that interactions between grains and air are primarily responsible for the observed scale effects. This is supported by the discrete element method data, which did not show these scale effects in the absence of air. Furthermore, the particle drag force accounted for a significant part of the observed scale effects. Cauchy number scale effects caused by unscaled particle stiffness resulting in varying dust formation with scale are found to be of secondary importance. Comparisons of the laboratory data to that of other studies and of natural events show that data normalization with Re is an effective method of quantitatively comparing laboratory results to natural events. This upscaling technique can improve hazard assessment in nature and is potentially useful for modeling industrial flows

Turkish-German innovation networks in the European research landscape

Research networks are regarded as channels for knowledge creation and diffusion and are thus essential for the development and integration of economies. In this paper we have a look at the long Turkish-German-migration history which should offer opportunities for both countries to benefit from brain circulation, transnational entrepreneurs and research networks. The present paper examines the structure of research networks of the European Framework Programmes (FP) that are established by joint participation of organizations in research projects, in particular German research organizations with Turkish participants in FP5 to FP7 in the knowledge-intensive technology fields ICT, Biotechnology and Nanoscience. A better understanding of these networks allows for improving the design of research policies at national levels as well as at the EU level. The empirical examination of network properties reveals that the diverse networks show a range of similarities in the three technology fields in each FP such as the small-world properties. Moreover, our findings show that German actors play a specific role in most examined research networks with Turkish participation

Do silêncio à enunciação: formação de identidades nas narrativas de Moacyr Scliar

A premissa de Tzvetan Todorov sobre a importância de o sujeito, quando ora de seu país de origem, reconhecer seu lugar de enunciação para continuar a existir, serviu como ponto de partida para analisar, em quatro narrativas de Moacyr Scliar, como cinco de seus personagens, exilados de primeira ou segunda geração no Brasil, buscaram este lugar, criando, para isso, novas identidades ou tornando-se híbridos. Edward Said, que escreveu sobre exílio; Stuart Hall, sobre identidade e, finalmente, Nestor Canclini, sobre culturas híbridas, forneceram o suporte teórico para a análise.Tzvetan Todorov’s premise on the importance of the subject, when away from his home country, to recognize the enunciation place in order to go on being, was our starting point to analyze, in four of Moacyr Scliar’s narratives, the ways five of his characters, exiled in Brazil at first or second generation, searched for such a place, thus creating new identities or becoming hybrids. Edward Said, who wrote about the exile, Stuart Hall, who wrote about identity and, finally Nestor Canclini, who wrote about hybrid cultures, supplied us with theory for the analysis

Cosplay and cosplayers: when the pop culture is seriously taken

Cena Cosplay: comunicação, consumo e memória nas culturas juvenis, organized by Monica Rebecca Ferrari Nunes, presents the outcomes of the research coordinated by the author at the Postgraduate Studies in Communication and Consumption Practices, ESPM - SP, sponsored by CNPq. The book has seven parts, besides an introduction and has a two-way approach: the memories of the stories that aroused interest in cosplay practice and its "reverse", that is, the strategies by which the cosplay scene ensures its memory in youth cultures. Iuri Lotman, Paul Zumthor, Marshall McLuhan, Monica Rebecca Ferrari Nunes, Roger Silverstone, Mircea Eliade, among others, give the theoretical support of the conclusions of the ten authors of the book, who attended the events of animations (animês) in São Paulo, Belo Horizonte, Rio de Janeiro and Vitoria, from 2012 to the beginning of 2014.Keywords: comics; narrative language; visual communication; semiology

Comunicação e memória em textos de coletivos de teatro feminista no Brasil: Boneca de pano (SC, 2014) e Entre Nós: buzinas, chicotes e ácidos (CE, 2017)

Although feminist movements began more than a hundred years ago in Brazil, there are still few Brazilian groups that develop dramaturgy written by and for women, even considering amateur theater. We present in this article the analysis of two theatrical texts (or scripts), still unpublished: Boneca de pano, by the Santa Catarina theater collective (Em) Companhia de Mulheres, and Entre Nós: buzinas, chicotes e ácidos, by the Ceará collective Arremate de Teatro. We aim to understand, when comparing these two theatrical narratives, similarities and differences of the themes in question, considering their places of production, as well as their origins. We start from the hypothesis that theatrical narratives written by collectives that consider themselves feminists function as an authorized space for Brazilian women to speak, for the identification and rupture of behaviors inherited from the patriarchal culture. We confirm, based on the theoretical frame of theater, discourse analysis, cultural studies, gender studies and social memory, that the two texts under analysis present themselves as equally potent forms of catharsis, sensitization and resistance to the domestication and oppression to which women are still submitted.Apesar de os movimentos feministas terem se iniciado há mais de cem anos no Brasil, ainda são poucos os grupos brasileiros que desenvolvem dramaturgia escrita por e para mulheres, ainda que se considere o teatro amador. Apresentamos neste artigo a análise de dois textos teatrais (ou roteiros), ainda inéditos: Boneca de pano, do coletivo de teatro catarinense (Em) Companhia de Mulheres, e Entre Nós: buzinas, chicotes e ácidos, do coletivo cearense Arremate de Teatro. Temos como objetivo compreender, ao compararmos essas duas narrativas teatrais, semelhanças e diferenças dos temas em pauta, considerando seus locais de produção, bem como suas origens. Partimos da hipótese de que narrativas teatrais redigidas por coletivos que se assumem feministas funcionam como um espaço autorizado de fala das brasileiras, de identificação e de ruptura de comportamentos herdados da cultura patriarcal. Confirmamos, a partir dos suportes teóricos sobre teatro, análise do discurso, estudos culturais, de gênero e memória social, que os dois textos em tela se apresentam como formas igualmente potentes de catarse, sensibilização e resistência à domesticação e à opressão a que as mulheres ainda são submetidas
