We present a lattice QCD calculation of the heavy-light decay constants fB and fBs performed with Nf = 2 maximally twisted Wilson fermions, at four values of the lattice spacing. The decay constants have been also computed in the static limit and the results are used to interpolate the observables between the charmand the infinite-mass sectors, thus obtaining the value of the decay constants at the physical b quark mass. Our preliminary results are fB = 191(14)MeV, fBs = 243(14)MeV, fBs/ fB = 1.27(5). They are in good agreement with those obtained with a novel approach, recently proposed by our Collaboration (ETMC), based on the use of suitable ratios having an exactly known static limit.
We present first results from runs performed with Nf = 2+1+1 flavours of dynamical twisted mass fermions at maximal twist: a degenerate light doublet and a mass split heavy doublet. An overview of the input parameters and tuning status of our ensembles is given, together with a comparison with results obtained with Nf = 2 flavours. The problem of extracting the mass of the K- and D-mesons is discussed, and the tuning of the strange and charm quark masses examined. Finally we compare two methods of extracting the lattice spacings to check the consistency of our data and we present some first results of cPT fits in the light meson sector.
"Entre direitos iguais, a força decide", proferiu karl marx ao descrever a antinomia do direito em situações antagônicas das relações de produção capitalistas, em que "o direito [oferece resistência] ao direito" nesse ponto, marx aborda uma questão que se situa no centro de todas as teorias jurídicas críticas: que tipo de violência é velada por meio do mecanismo de ocultação denominado "direito"? Para responder a esta questão, tentar-se-á, a seguir, tornar a teoria da hegemonia de antonio gramsci e seu modelo de direito hegemônico produtivos para o campo da teoria do direito. Tal tarefa tem de lidar com a dupla dificuldade de que, por um lado, gramsci não foi um teórico do direito no sentido mais estrito, razão pela qual o potencial de sua teoria para uma análise do direito raramente foi utilizada. Por outro lado, sua abordagem só pode ser empregada por meio de uma crítica às restrições relacionadas a seu tempo. isso se aplica especialmente à sua concepção de economia como a base e a núcleo essencialista oculto (laclau; mouffe, 2001:69), assim como à sua ideia de 'classismo' sob a forma de um enfoque unilateral das classes, em que há preferencialmente mais de um "pluralismo de poder" e inúmeras lutas (litowitz, 2000: 536). Recuperar-se-á, consequentemente, argumentos-chave, ampliando-os pela utilização das recentes descobertas feitas pelas abordagens feminista e neomaterialista da teoria jurídica, bem como as análises de foucault acerca das tecnologias de poder. por fim, uma interpretação da teoria sistêmica das autonomizações comunicativas.
O 11 de setembro acelerou o desenvolvimento de uma arquitetura transnacional de segurança que intervém profundamente nas liberdades civis individuais, tanto nos direitos básicos dos cidadãos dos Estados como nos direitos humanos dos cidadãos mundiais. O artigo delineia essa arquitetura, mostra como ela dissolve as categorias jurídicas tradicionais que preservam a liberdade e discute por que hoje se aceita amplamente a prioridade da segurança sobre a liberdade.
Os limites da tolerância
(2009)
Este artigo apresenta os elementos constitutivos do conceito de tolerância e discute duas concepções diferentes do termo, como permissão e como respeito moral, que expressam modos diversos de demarcar os limites da tolerância. A tolerância é apresentada como um conceito que, para ganhar algum conteúdo, depende normativamente de um direito à justificação baseado na idéia de um uso público da razão segundo o qual as práticas e as instituições político-jurídicas que determinam a vida social dos cidadãos devem ser justificáveis à luz de normas que eles não podem recíproca e genericamente rejeitar.
Background: A growing number of German hospitals have been privatized with the intention of increasing cost effectiveness and improving the quality of health care. Numerous studies investigated what possible qualitative and economic consequences these changes issues might have on patient care. However, little is known about how this privatization trend relates to physicians' working conditions and job satisfaction. It was anticipated that different working conditions would be associated with different types of hospital ownership. To that end, this study's purpose is to compare how physicians, working for both public and privatized hospitals, rate their respective psychosocial working conditions and job satisfaction.
Methods: The study was designed as a cross-sectional comparison using questionnaire data from 203 physicians working at German hospitals of different ownership types (private for-profit, public and private nonprofit).
Results: The present study shows that several aspects of physicians' perceived working conditions differ significantly depending on hospital ownership. However, results also indicated that physicians' job satisfaction does not vary between different types of hospital ownership. Finally, it was demonstrated that job demands and resources are associated with job satisfaction, while type of ownership is not.
Conclusion: This study represents one of a few studies that investigate the effect of hospital ownership on physicians work situation and demonstrated that the type of ownership is a potential factor accounting for differences in working conditions. The findings provide an informative basis to find solutions improving physicians' work at German hospitals.
Die Arbeit analysiert den Begriff sowie den Wert der Freiheit in den Schriften des kanadischen Philosophen Charles Taylor, unter Bezugnahme auf dessen politische Philosophie und philosophische Anthropologie. Die begriffliche Klärung basiert auf einer Systematisierung der positiven Verwendung des Freiheitsbegriffes in Taylors Gesamtwerk. Die Wertanalyse interpretiert die Ergebnisse der Systematisierung in Bezug auf die Frage, ob Freiheit in Taylors Verständnis ein extrinsischer oder ein intrinsischer Wert ist.
In its admissibility decision in the Al-Saadoon case the ECtHR held that the United Kingdom had jurisdiction over the applicants, who had been arrested by British forces and kept in a British-run military prison in Iraq. Just before the respective mandate of the Security Council expired on 31 December 2008, the applicants were transferred to Iraqi custody at Iraqi request and thereby exposed to the risk of an unfair trial followed by capital punishment. In this respect, the case resembles the Soering case, although the applicants were, unlike Soering, not on British territory but on occupied Iraqi soil before they were handed over. This aspect raises the question of Iraqi sovereignty as a norm competing with the UK's human rights obligations. The authors trace back the ECtHR's case law concerning the extraterritorial application of the Convention and analyse the UK judgments and the ECtHR's admissibility decision in the Al-Saadoon affair from this angle. Furthermore they consider the doctrinal consequences of the ECHR's extraterritorial effect in cases like Soering and Al-Saadoon, where contracting parties violate guarantees of the Convention by exposing a person within their jurisdiction to a risk of a treatment contrary to these guarantees by a third state. Finally, they test the argument brought forward by the UK that not transferring the applicants would have violated Iraqi sovereignty and establish patterns how the ECtHR and the UK Courts did cope in the past with international law norms potentially competing with the Convention.
