Tecnologias da informação e da comunicação e a polêmica sobre direito autoral: o caso Google Book Search

Anotamos, neste trabalho, reflexões sobre as conseqüências das Tecnologias da Informação e da Comunicação (TICs) para o direito autoral e sobre os atores do processo informativo. Partimos da lei do direito autoral vigente no Brasil, perguntando-nos como tais normas protegem as obras intelectuais no contexto digital e até que ponto há legalidade e legitimidade na digitalização de livros protegidos, disponibilizados on-line, tomando como exemplo o caso "Google Book Search". Constatamos que a lei atual pouco defende os direitos dos autores e dos leitores, pois se volta para a proteção dos interesses privados comerciais, e que a sociedade civil encontra formas de ampliar o fluxo comunicativo em decorrência da facilidade de reprodução e distribuição de cópias de obras intelectuais proporcionada pelas TICs.

Visibilidad de las revistas latinoamericanas de bibliotecología y ciencia de la información a través de Google Scholar

Las revistas académico-científicas son uno de los principales canales de comunicación y difusión de los resultados de investigación. Sin embargo no todas tienen el mismo prestigio y grado de influencia en la comunidad científica. De su calidad y visibilidad dependen, en gran medida, las posibilidades de que un trabajo sea conocido, leído y citado. Esta investigación se propone determinar la visibilidad en Google Scholar de un conjunto de revistas latinoamericanas de Bibliotecología y Ciencia de la Información, y clasificarlas según su grado de visibilidad. Utilizando la aplicación Publish or Perish para recuperar las citas de las revistas se calcularon indicadores basados en la citación. Se combinaron técnicas de análisis multivariado de datos para realizar agrupamientos de revistas según su grado de visibilidad, y se elaboraron representaciones gráficas que facilitan la interpretación de los resultados y la identificación de los grupos de revistas con alta, media y baja visibilidad.

Wound infection following stoma takedown: primary skin closure versus subcuticular purse-string suture.

Abstract: Background Stoma closure has been associated with a high rate of surgical site infection (SSI) and the ideal stoma-site skin closure technique is still debated. The aim of this study was to compare the rate of SSI following primary skin closure (PC) versus a skin-approximating, subcuticular purse-string closure (APS). Methods All consecutive patients undergoing stoma closure between 2002 and 2007 by two surgeons at a single tertiary-care institution were retrospectively assessed. Patients who had a new stoma created at the same site or those without wound closure were excluded. The end point was SSI, determined according to current CDC guidelines, at the stoma closure site and/or the midline laparotomy incision. Results There were 61 patients in the PC group (surgeon A: 58 of 61) and 17 in the APS group (surgeon B: 16 of 17). The two groups were similar in baseline and intraoperative characteristics, except that patients in the PC group were more often diagnosed with benign disease (p = 0.0156) and more often had a stapled anastomosis (p = 0.002). The overall SSI rate was 14 of 78 (18%). All SSIs occurred in the PC group (14 of 61 vs. 0 of 17, p = 0.03). Conclusions Our study suggests that a skin-approximating closure with a subcuticular purse-string of the stoma site leads to less SSI than a primary closure. Randomized studies are needed to confirm our findings and assess additional end points such as healing time, cost, and patient satisfaction.

Tarracomap: Development of an archaeological application on Google Maps navigation System

This paper describes the result of a research about diverse areas of the information technology world applied to cartography. Its final result is a complete and custom geographic information web system, designed and implemented to manage archaeological information of the city of Tarragona. The goal of the platform is to show on a web-focused application geographical and alphanumerical data and to provide concrete queries to explorate this. Various tools, between others, have been used: the PostgreSQL database management system in conjunction with its geographical extension PostGIS, the geographic server GeoServer, the GeoWebCache tile caching, the maps viewer and maps and satellite imagery from Google Maps, locations imagery from Google Street View, and other open source libraries. The technology has been chosen from an investigation of the requirements of the project, and has taken great part of its development. Except from the Google Maps tools which are not open source but are free, all design has been implemented with open source and free tools.

Matching stages of heavy-ion collision models

Heavy-ion reactions and other collective dynamical processes are frequently described by different theoretical approaches for the different stages of the process, like initial equilibration stage, intermediate locally equilibrated fluid dynamical stage, and final freeze-out stage. For the last stage, the best known is the Cooper-Frye description used to generate the phase space distribution of emitted, noninteracting particles from a fluid dynamical expansion or explosion, assuming a final ideal gas distribution, or (less frequently) an out-of-equilibrium distribution. In this work we do not want to replace the Cooper-Frye description, but rather clarify the ways of using it and how to choose the parameters of the distribution and, eventually, how to choose the form of the phase space distribution used in the Cooper-Frye formula. Moreover, the Cooper-Frye formula is used in connection with the freeze-out problem, while the discussion of transition between different stages of the collision is applicable to other transitions also. More recently, hadronization and molecular dynamics models have been matched to the end of a fluid dynamical stage to describe hadronization and freeze-out. The stages of the model description can be matched to each other on space-time hypersurfaces (just like through the frequently used freeze-out hypersurface). This work presents a generalized description of how to match the stages of the description of a reaction to each other, extending the methodology used at freeze-out, in simple covariant form which is easily applicable in its simplest version for most applications.

La actividad de los medios tradicionales en las redes Google Plus y Linkedin

L'era 2.0 ha arribat als nostres dies i amb això, les xarxes socials ja formen part de la vida diària de molts habitants del planeta. Cada dia, milions de persones es connecten i interactuen a través d'elles amb la finalitat d'entretenir-se i informar-se. Tot això ha fet que molts mitjans de comunicació tradicionals hagin hagut de renovar-se per oferir als usuaris un servei que anys enrere ni es plantejaven i que en alguns casos els ha agafat desprevinguts. Per això, el present Treball Final de Carrera analitza l'activitat dels mitjans El País, El Mundo, La Vanguardia i El Periódico de Catalunya a les xarxes socials Google+ i LinkedIn. La popularitat, la interactivitat i la influència seran factors determinants per veure quin és el mitjà que realitza un millor ús d'aquestes xarxes socials, minoritàries, que guanyen terreny en el dia a dia.

Edge matching puzzles as hard SAT/CSP benchmarks

Recently, edge matching puzzles, an NP-complete problem, have rececived, thanks to money-prized contests, considerable attention from wide audiences. We consider these competitions not only a challenge for SAT/CSP solving techniques but also as an opportunity to showcase the advances in the SAT/CSP community to a general audience. This paper studies the NP-complete problem of edge matching puzzles focusing on providing generation models of problem instances of variable hardness and on its resolution through the application of SAT and CSP techniques. From the generation side, we also identify the phase transition phenomena for each model. As solving methods, we employ both; SAT solvers through the translation to a SAT formula, and two ad-hoc CSP solvers we have developed, with different levels of consistency, employing several generic and specialized heuristics. Finally, we conducted an extensive experimental investigation to identify the hardest generation models and the best performing solving techniques.

String theory dualities and supergravity divergences

We demonstrate how duality invariance of the low energy expansion of the four-supergraviton amplitude in type II string theory determines the precise coefficients of multiloop logarithmic ultraviolet divergences of maximal supergravity in various dimensions. This is illustrated by the explicit moduli-dependence of terms of the form ¿2k R4, with k ¿ 3, in the effective action. Furthermore, we show that in the supergravity limit the perturbative contributions are swamped by an accumulation of non-perturbative effects of zero-action instantons.
