Gravitational Waves: completeness and connectedness by geodesics

Only few months ago some physicists gave the official announcement that gravitational waves exist, but, from a geometrical point of view, they have always been ``real objects'' and their properties have been widely investigated. The aim of this talk is introducing generalized plane waves and discussing some of their properties such as geodesic connectedness and geodesic completeness.

Stock price and volume effects associated with changes in the composition of the FTSE Bursa Malaysian KLCI

We examine the stock price and volume effects associated with changes in the composition of the FTSE Bursa Malaysia Kuala Lumpur Composite Index (KLCI), over the time period of 2005–2012. We find evidence to support the price pressure hypothesis for both additions to and deletions from the KLCI. This is because significant stock price and trading volume effects in the pre index revision period are entirely reversed after the announcement of the news. Our empirical findings can be explained by the market microstructure literature. Significant changes in liquidity cause trading volume and stock prices to reverse back to their original level before the index revisions took place.

Forma ecclesiae : Per un cattolicesimo di popolo oggi: “per tutti” anche se non “di tutti”

La radicalité du changement culturel provoque une crise de la forma ecclesiae et introduit la question relative à quelle est la forme de l’Église la plus appropriée à l’annonce de l’évangile. L’Église italienne, que le présent travail a l’intention d’assumer en qualité de point de référence particulier, en est également intéressée: contrairement au passé, même le plus récent, la foi chrétienne n’est plus un patrimoine «de tous». La question se pose puisque, au nom de l’évangile, l’action de l’Église ne peut pas disperser, pourtant, le caractère universel de la foi en soi même (son être «pour tous»). Dans un tel scénario, s’enclenche le but que cette thèse se pose de poursuivre sur le plan de la pensée théologique-pastorale: elle veut accompagner l’Église en son être à l’intérieur de cette tension entre l’instance théologique d’une foi qui est «pour tous» et le donné sociologique dont il émerge qu’elle n’est plus «de tous». Beaucoup de projets contemporaines de réforme pastorale ont l’intention de faire face aux transformations de la culture afin d’empêcher tout injustifiée domestication. Cependant, comme cette thèse essaie à le prouver, ils risquent souvent de suggérer une rupture avec le passé récent du corps ecclésial. Pour eux la référence polémique est représentée par cette figure de «catholicisme populaire» avec qui, dans le contexte de la «civilisation paroissiale», l’expérience chrétienne est réussie à s’enraciner dans le tissu social. Dans ces projets, il est – en effet – assimilé d’une manière restrictive à une sorte de «catholicisme de masse», basé seulement sur des processus religieux de socialisation et d’uniformisation de l’expérience. Au contraire, le but de ce travail consiste en un essai de compréhension renouvelée de cette figure de vie chrétienne. Elle n’est retenue seulement selon la particulière forme historique qu’elle a adoptée dans le demain passé, marqué par une situation d’homogénéité culturelle, d’une Église de peuple, mais aussi comme principe opératoire qui désigne la capacité du christianisme de se réaliser en tant qu’élévation et transfiguration des formes anthropologiques de base. Cette perspective dynamique permet de trouver dans le «catholicisme populaire» un principe écclesio-génétique qui exalte l’interaction entre l’initiative ecclésiale et la sensibilité des croyants, et qui, tout en défendant la qualité théologale de l’expérience chrétienne, ne méprise pas la valeur pédagogique de son enracinement religieux. La dynamique qui préside au «catholicisme populaire», grâce à la confrontation avec une étude sur le terrain, conduit à l’individuation de certaines provocations à propos de la structure du corps ecclésial, en ce qui concerne les représentations, les actions, les sujets et les limites qui le caractérisent. Elles sont transposées de manière à envisager une réforme de l’Église qui s’avère applicable pour le présent et qui cherche à garder le caractère universel-non formel de la foi, c’est à dire son «pour tous».

Using a Dialogue Manager to Improve Semantic Web Search

Question Answering systems that resort to the Semantic Web as a knowledge base can go well beyond the usual matching words in documents and, preferably, find a precise answer, without requiring user help to interpret the documents returned. In this paper, the authors introduce a Dialogue Manager that, through the analysis of the question and the type of expected answer, provides accurate answers to the questions posed in Natural Language. The Dialogue Manager not only represents the semantics of the questions, but also represents the structure of the discourse, including the user intentions and the questions context, adding the ability to deal with multiple answers and providing justified answers. The authors’ system performance is evaluated by comparing with similar question answering systems. Although the test suite is slight dimension, the results obtained are very promising.

The Constitution of Subject Slave in the Journal: “Dezenove de Dezembro"

  ABSTRACT: This article is based on the contributions of discourse analysis from French orientation, which combines the linguistic aspect to the socio-historical, it understands, therefore, that the speech is the place of ideological manifestations (ORLANDI, 1984) and can not be dissociated from its production condition, that is, of all his surroundings and constituent: who, when, where. Starting with four announcement on runaway slaves and two missing pets, published in the Journal: Dezenove de Dezembro, in circulation in the State of Paraná, in the nineteenth century, we analyze the position of the press at the time to refer to the runaway slave. The appreciation of the words used by the enunciator has revealed that he had the intention to highlight the condition of "object" of the black slave, limiting his identity to their physical particulars, referring to aspects found in the missing pets announcements. Thereby, we find, in these analyzed announcements, which the formation of the subject slave in the Paraná society of the nineteenth century is subjected, and it can not be disconnected of ideological and historical instances.

The effects of sense and the production conditions of the discourse about woman in the newspaper "the mentor of Brazilian women"

More than understanding a speech, we need to decode it to then seek to understand how this discourse was made and what direction effects it produces. The Mentor of the Brazilians from Sao Joao del Rei - our object of study in this article - since its announcement in 1829, it was proposed to be like the newspaper's name itself shows, a Mentor, a newspaper to guide, advise women the inclusion in the political and moral life of the country, but without forgetting the family and their deveres. Para rationale of this study are taken as the essence of the studies Pêcheux and Eni Orlandi, the French Discourse Analysis (DA), trying to understand the speech of the mining journal in their production conditions in the nineteenth century. Understanding that social memory leads to a discursive memory that formulates the speeches already in place, giving rise to the social-historical context of ideological and enunciator statement. In addition, it is necessary to establish the role of the analyst in the process of understanding of the subject matter, because according to Orlandi (2008), the subject has his body tied to the body of the senses; subject and senses has its corporeality, made at the meeting of the materiality of language and history. In this perspective, enunciator and analyst embody the senses three cutouts of the weekly newsletter: a) the ad in the Astro de Minas newspaper talking about the first Mentor of the Brazilians women edition, b) the No. 1 edition and c) No.10 edition of the Mentor of the Brazilians women.
