This article seeks to retrace some of the empirical, historical and sociological elements of Max Weber Sociology of music. Even if he is first and foremost interested in the process of rationalisation throughout western civilisation, his Sociology of music is founded on the idea of the technical medium, which he explores in several different directions. This idea will be examined here by means of several examples drawn from western music, particularly from the romantic piano repertoire.

Objective: In this study, we determined the protective effect of isoflavones from Glycine max on human umbilical vein endothelial cell (ECV304) damage induced by hydrogen peroxide (H(2)O(2)) and on nitric oxide (NO) production. Methods: We studied the regulation of NO synthesis in cultured human endothelial cells by phytoestrogens contained in soy extracts in the presence or absence of ICI 182,780 or N(omega)-nitro-L-arginine methyl esther and determined the protective effect of these isoflavones on ECV304 damage induced by H(2)O(2). Results: We show that soy extracts activate NO synthesis in endothelial cells and protect against cell damage. Conclusions: In conclusion, soy isoflavones markedly protect ECV304 cells against H(2)O(2) damage and promote NO synthesizing. Therefore, these isoflavones call potentially act as an NO promoter and as an antioxidant.

We describe the orthodontic treatment of a patient with Klippel-Trenaunay-Weber syndrome (KTWS) who received orthodontic treatment that included rapid palatal expansion and orthognathic surgery. There is no report in the literature with this orthodontic treatment protocol, that was considered successful. The pros and cons of this approach as well as the risks involved are discussed.

Interval-valued versions of the max-flow min-cut theorem and Karp-Edmonds algorithm are developed and provide robustness estimates for flows in networks in an imprecise or uncertain environment. These results are extended to networks with fuzzy capacities and flows. (C) 2001 Elsevier Science B.V. All rights reserved.

We report a further characterization of the genomic region containing the soybean supernodulation gene NTS-1. We performed a search for new markers linked to NTS-1 by combining DNA amplification fingerprinting (DAF) and bulked segregant analysis (BSA). The search resulted in one cloned polymorphism (B44-456) linked in trans, 8.5cM from the locus. Southern hybridization showed duplication of the B44-456 sequence in the soybean genome. Additionally, a DNA database search revealed one Arabidopsis thaliana genomic clone from chromosome I possessing 62% homology to the B44-456 marker. A relatively low number of polymorphisms were identified by several PCR marker technologies for this soybean genomic region, providing an additional support for its highly conserved and/or duplicated organization.

At the core of the analysis task in the development process is information systems requirements modelling, Modelling of requirements has been occurring for many years and the techniques used have progressed from flowcharting through data flow diagrams and entity-relationship diagrams to object-oriented schemas today. Unfortunately, researchers have been able to give little theoretical guidance only to practitioners on which techniques to use and when. In an attempt to address this situation, Wand and Weber have developed a series of models based on the ontological theory of Mario Bunge-the Bunge-Wand-Weber (BWW) models. Two particular criticisms of the models have persisted however-the understandability of the constructs in the BWW models and the difficulty in applying the models to a modelling technique. This paper addresses these issues by presenting a meta model of the BWW constructs using a meta language that is familiar to many IS professionals, more specific than plain English text, but easier to understand than the set-theoretic language of the original BWW models. Such a meta model also facilitates the application of the BWW theory to other modelling techniques that have similar meta models defined. Moreover, this approach supports the identification of patterns of constructs that might be common across meta models for modelling techniques. Such findings are useful in extending and refining the BWW theory. (C) 2002 Elsevier Science Ltd. All rights reserved.

The subject of this study was a typical, if in some respects well qualified, U.S. ambassadorial appointee for his time, the early twentieth century: an attorney, judge, and politician who served competently in his one diplomatic assignment, in Berlin, before returning to private life.—Ed.

O objetivo deste texto ?? iniciar um levantamento da dificuldades impostas ?? reforma administrativa a partir da considera????o do problema da neutralidade da burocracia versus o requisito da autonomia de decis??o, elemento fundamental do Modelo de Administra????o P??blica Gerencial. Tal problema assume especial relev??ncia frente aos objetivos de aumentar a governan??a do Estado e constitui um dos desafios centrais do Plano Diretor da Reforma do Aparelho do Estado, particularmente no que diz respeito ?? forma de administra????o do chamado ???n??cleo estrat??gico??? ??? respons??vel pela defini????o das leis e pol??ticas p??blicas ??? e das ???atividades exclusivas de Estado??? ??? caracterizadas pelo exerc??cio do poder de legislar e tributar, fiscalizando, regulamentando e transferindo recursos. Para isso, a discuss??o est?? organizada em quatro se????es. Na primeira, s??o rapidamente apresentados os conceitos de governabilidade e governan??a, com ??nfase no fato de que a distin????o entre eles representa apenas um recurso anal??tico. Na segunda se????o, a partir das distin????es cl??ssicas de Max Weber entre pol??tica e administra????o, pol??ticos e burocratas, busca-se caracterizar a neutralidade burocr??tica e mostrar que representa, na realidade, apenas um dos elementos de uma constru????o t??pico ideal, cada vez mais distante de qualquer correspond??ncia com o mundo real. Em seguida, comenta-se rapidamente o processo de mudan??a do modelo de administra????o p??blica; e s??o apresentadas algumas das caracter??sticas do chamado Modelo de Administra????o P??blica Gerencial que, em lugar da neutralidade, implicam elevado grau de autonomia por parte dos agentes burocr??ticos. Por fim, s??o tecidas algumas considera????es, procurando mostrar que, da mesma maneira que a neutralidade, a autonomia burocr??tica apresenta dificuldades e que a proposta da ???autonomia imersa??? ou ???autonomia inserida??? exibe implica????es que merecem reflex??o mais demorada.

A telangiectasia Hemorrágica Hereditária ou Síndrome de Rendu-Osler-Weber é uma rara displasia fibrovascular que torna a parede vascular vulnerável a traumatismos e rupturas, provocando sangramentos em pele e mucosas. Apresenta herança autossômica dominante. É caracterizada por epistaxes de repetição, telangiectasias mucocutâneas, malformações arteriovenosas viscerais e história familiar positiva. A epistaxe costuma ser a primeira e a principal manifestação. Está associada a malformações arteriovenosas em vários órgãos. São possíveis complicações hematológicas, neurológicas, pulmonares, dermatológicas e de trato gastrointestinal. A terapia é de suporte e de prevenção de complicações. Neste estudo, relata-se um caso de um paciente com a síndrome, atendido no Ambulatório de Otorrinolaringologia da Faculdade de Medicina de Marília, e faz-se uma revisão bibliográfica de sua etiopatogenia, manifestações clínicas e terapêutica clínico-cirúrgica.
