Direito autoral e tecnologias de informação e comunicação no contexto da produção, uso e disseminação de informação: um olhar para as Licenças Creative Commons

The development of information and communication technologies, in particular, Internet, and its Web 2.0 information environment has led to significant changes in contemporary society as to the ways of producing informational content. Collaboration and remix, favored by the new services and applications resulting from the development of the Web, are practices which contribute for the exponential growth of information producers. An important part of humanity ceases to be a mere consumer of symbolic goods and becomes a member in a society that sees in the collaboration and remix a new form of creation, use and dissemination of intellectual content. However, as such practices involve the production and use of information intelectual content, and are ruled by a legisltion which determine determines under what conditions the author and the user must produce and use the intellectual work. This legislation established for a context prior to the develompment of the Web has created an imbalance in the context of Web 2.0 which needs to be solved in some way so as to provide the required rebalance for the flow of information. This study explores the collaborative Web environment, the scope of copyright law in Web enviroment and the Creative Commons licenses as an alternative for producers and users of information to create, recreate, share, use, reuse and disseminate legally the intellectual production for the benefit of the construction of knowledge.

In vitro comparison of 1.5 mm vs. 2.0 mm screws for fixation in the sagittal split osteotomy

Purpose: Numerous "in vitro" investigations have been conducted to evaluate the role of screw size and pattern in determining optimal resistance to deformation, often these have been controversial. The aim of this study was to evaluate the effect of screw size and insertion technique on the stability of sagittal split osteotomies.Materials and methods: This study used twenty polyurethane replicas of human hemimandibles with a prefabricated sagittal split ramus osteotomy (SSRO). The hemimandibles were stabilized with 1.5 mm and 2.0 mm titanium screws inserted in an inverted L configuration. All specimens were tested to determine the strength and stability of the fixation.Results: In all cases there was failure of the synthetic bone before there was any evidence of screw failure. There were no significant differences in the load necessary to make the construct fail between the 1.5 or 2.0 mm screw sizes.Conclusion: There was no statistically significant difference between the strengths achieved with screws of 1.5 and 2.0 mm diameters for fixation of SSRO performed in synthetic mandibles. There was no fracture of the 1.5 mm or 2.0 mm diameter screws in any of the tests. 1.5 mm diameter screws in an inverted L pattern have as much stability and mechanical resistance as a 2.0 mm screw, may be safely used for this procedure.

Nilpotent orbits and codimension-2 defects of 6d N = (2, 0)theories

We study the local properties of a class of codimension-2 defects of the 6d N = (2, 0) theories of type J = A, D, E labeled by nilpotent orbits of a Lie algebra $g, where g is determined by J and the outer-automorphism twist around the defect. This class is a natural generalization of the defects of the six-dimensional (6d) theory of type SU(N) labeled by a Young diagram with N boxes. For any of these defects, we determine its contribution to the dimension of the Higgs branch, to the Coulomb branch operators and their scaling dimensions, to the four-dimensional (4d) central charges a and c and to the flavor central charge k. © 2013 World Scientific Publishing Company.

Relações públicas 2.0: um olhar sobre o twitter corporativo

This project analyses in theory the transformations that have occurred in the information society in the range of the organizational communication, developing the internet historical trajectory as a technology of transformation. We highlight the cyber culture study as a cultural expression that emerges with the current society needs, observed by an optic that focuses on digital communication, emphasizing the digital environment as a space for information trade, in the interior premise of communication: the relationship. The organizations will be approached in the project through a channel for communication, in the digital range, besides the traditional forms. In regards to the enterprises we will study in depth the consumer of this society of consumerism, with a special look at the generation Y, deeply inserted in this virtual context, describing the current type of consumption, mainly the relations of consumption with the social medias. After this transforming process in which individuals are inserted in the digital environment we intend to focus in the corporate digital communication, analyzing the organizational digital communication in the contemporary society. We emphasize the theories of Public Relations, one of the main activities, able to do planning, to put together and execute the strategies that will be used in the social medias as a form of corporate digital communication. We explicit Twitter as a tool of the corporate digital communication, because it reaffirms the theories described throughout the research as one of the most essential social media to turn loyal the relationship between the consumer and the organization in real time, as an example is the organization “camisetaria” that became a success case in the social medias; we detail the participation of the company on Twitter and the reach of this network through it’s strategies in the corporate digital communication
