The French fifth Republic as an opportunity structure:a neo-institutional and cultural approach to the study of leadership politics

The Gaullist settlement of 1958 reconfigured the political institutions of France, introducing into the republican mainstream a new form of leadership politics. Adapting the literature on political opportunity structure (POS) theory, and using the French left as a case study, can help us understand how political parties, ideology and leadership adapt to political institutions and norms. It also illuminates what the consequences are of such adaptation in the contemporary period, particularly as regards the institutionally bound roles of political 'character', protocol and discourse. The paper appraises the relevance and appropriateness of POS theory to leadership politics in France.

The Cascade Neo-Fuzzy Architecture and its Online Learning Algorithm

In the paper learning algorithm for adjusting weight coefficients of the Cascade Neo-Fuzzy Neural Network (CNFNN) in sequential mode is introduced. Concerned architecture has the similar structure with the Cascade-Correlation Learning Architecture proposed by S.E. Fahlman and C. Lebiere, but differs from it in type of artificial neurons. CNFNN consists of neo-fuzzy neurons, which can be adjusted using high-speed linear learning procedures. Proposed CNFNN is characterized by high learning rate, low size of learning sample and its operations can be described by fuzzy linguistic “if-then” rules providing “transparency” of received results, as compared with conventional neural networks. Using of online learning algorithm allows to process input data sequentially in real time mode.

Apicectomías de dientes premolares y molares mandibulares en el conejo de raza neo zelandesa: estudio histológico usando distintos materiales de obturación apical

La apicectomía es una técnica de cirugía odontológica humana y veterinaria, que consiste en la amputación o resección de la porción más apical de la raíz dentaria y la retrobturación del ápice con algún material, con el objetivo de conservar el diente afectado de alguna patología apical. Se han usado gran variedad de materiales para la obturación, como amalgama, gutapercha, ionómero de vidrio, composite, MTA e hidróxido de calcio. En este estudio pretendemos comprobar la viabilidad de la técnica de la realización de la apicectomías en premolares y molares mandibulares, usando distintos materiales de retrobturación como son el iónomero de vidrio Ketac Cem μ® y el composite Tetric EvoFlow® en el conejo de experimentación de raza Neozelandesa. Realizamos las apicectomías de los dientes 407, 408 y 409 (3º premolar, 4º premolar y 1º molar inferior derecho), en una sola fase a diez animales. En el primer diente (407) solo se aplica un sellado del diente apicectomizado con hidróxido de calcio en polvo® y pasta Dycal® Dentin y no se coloca ningún material de obturación. En el segundo diente (408), se aplica un sellado con hidróxido de calcio en polvo® y pasta Dycal® Dentin y encima una retrobturación con ionómero de vidrio Ketac Cem μ® y en el tercer diente (409), se aplica un sellado con hidróxido de calcio en polvo® y pasta Dycal® Dentin y encima una retroturación con el composite Tetric EvoFlow®. A las 4 y 8 semanas se sacrificaron los animales y se realizó la toma de muestras. Estas fueron radiografiadas y posteriormente se realizaron cortes histológicos de los dientes apicectomizados y del tejido alrededor. Los cortes fueron teñidos con la tinción Levai-Laczkó y se realizó el estudio histológico cuantitativo y semicuantitativo, según la norma UNE-EN ISO 10993-6:2007, para medir la presencia de inflamación, fibrosis, infiltrados adiposos y cierre óseo del defecto...

The silent statue theme: complex imitation and Neo-Latin poetry

This paper analyses how the topic of the silent statue is dealt with in Neo-Latin literature. The subject matter comes from the epigrams about Pythagoras of the Palatine Anthology. There are numerous Neo-Latin imitations of this topic that are complex as various sources are used at the same time. The authors focus on an active reading of the epigrams of their predecessors, applying the traditional motive to new subjects and adapting it to the religious theme.

Epigenetics within the matrix:a neo-regulator of fibrotic disease

Fibrosis of any tissue is characterized by excessive extracellular matrix accumulation that ultimately destroys tissue architecture and eventually abolishes normal organ function. Although much research has focused on the mechanisms underlying disease pathogenesis, there are still no effective antifibrotic therapies that can reverse, stop or delay the formation of scar tissue in most fibrotic organs. As fibrosis can be described as an aberrant wound healing response, a recent hypothesis suggests that the cells involved in this process gain an altered heritable phenotype that promotes excessive fibrotic tissue accumulation. This article will review the most recent observations in a newly emerging field that links epigenetic modifications to the pathogenesis of fibrosis. Specifically, the roles of DNA methylation and histone modifications in fibrotic disease will be discussed.

"Natural" disasters as (neo-liberal) opportunity? Discussing post-hurricane Katrina urban regeneration in New Orleans

By providing a wide literature review, post-hurricane Katrina uneven urban regeneration in New Orleans is presented here by framing it within a historical perspective in order to underline how environmental threats too often seem to be not so much “natural” but rather man-made as well as to highlight both the reasons and the ways in which, in post-disaster reconstruction, competitive growth has been valued over equity, by directly benefiting those who were already the most advantaged. The aim is to highlight how environmental disasters can be considered as socially constructed phenomena, as they cannot be seen as a single event but rather as a process made by a series of progressive steps occurring within different spheres, which do not necessarily concern the environment only.

Acercamiento a la evoluci?n hist?rica del n?mero cero, en los sistemas de numeraci?n: mediterr?neo, oriental y americano

El presente trabajo final se enmarca en la L?nea de Investigaci?n Historia de las Matem?ticas del ?rea de Educaci?n Matem?tica de la Universidad del Valle. Este plantea una aproximaci?n a la evoluci?n hist?rica y epistemol?gica del n?mero cero a trav?s de los sistemas de numeraci?n: mediterr?neo, oriental y americano, con el fin de presentar la g?nesis del n?mero en menci?n a trav?s de sus antecedentes hist?ricos, su evoluci?n y su conceptualizaci?n como n?mero. Adem?s se relacionan los elementos te?ricos y algunos aspectos matem?ticos, como base de referencia y los elementos metodol?gicos que son tenidos en cuenta como enfoque para el desarrollo de este documento.
