Relações públicas e serviços virtuais: a comunicação entre as corporações da internet e o cibernauta

The objective of this study is to adress the action possibilities of the Public Relations professional in management of communication between the virtual services companies and their customers – the cybernauts. For this purpose, a bibliographical research was made about the cyberspace, Internet environment, as well as the cyberculture and the on-line consumer public. It was also studied the possible areas of Public Relations's action, their work tools and means of communication with the customer, in order to verify the specificities of communication mediated by new technologies. Based on these concepts, it was possible to propose an action of this professional in the organizations called dotcom, in order to contribute to the management of the communication flow between companies and this “invisible” public, which relates virtually to the organization, establishing different modes of interaction in relation to tradicional customers, requiring different strategies of relashionsip

Utilizing the CORBA platform in the construction of a highly immersive virtual environment

This article presents the implementation of a distributed system of virtual reality, through the integration of services offered by the CORBA platform (Common Object Request Broker Architecture) and by the environment of development of 3D graphic applications in real time, the WorldToolkit, of Sense8. The developed application for the validation of this integration is that of a virtual city, with an emphasis on its traffic ways, vehicles (movable objects) and buildings (immovable objects). In this virtual world, several users can interact, each one controlling his/her own car. Since the modelling of the application took into consideration the criteria and principles of the Transport Engineering, the aim is to use it in the planning, project and construction of traffic ways for vehicles. The system was structured according to the approach client/server utilizing multicast communication among the participating nodes. The chosen implementation for the CORBA was the Iona's ORBIX software. The performance results obtained are presented and discussed in the end.

Ubiquity of virtual disguisers and potential impact on ethical behavior

The widespread availability of wirelessly connected portable computers, smartphones and other mobile devices, and the pervasive presence of computer services in our everyday environment, has brought the prediction of Mark Weiser of future ubiquitous computer systems closer to reality. Some of these - ever-present, anywhere, anytime - ubiquitous computer services mean easier and pleasant lifestyles for many people, but the generalized availability of some classes of these softwares and computer services, known as virtual disguisers and Virtual Robots, can pose new ethical problems in a world of explosive growth of social networking sites. The objective of the present article is to investigate some of these problems, from an interdisciplinary philosophical perspective. Special emphasis shall be given to the potential impact on human conduct caused by disguisers and Virtual Robots. © 2011 IEEE.

Serviço de Referência Virtual: implantação do serviço de chat

Introduction: With the invention of the Internet and the Collaborative Web, libraries had to rethink the way to offer their services. Thus, the U.S. libraries began a search for technological innovations in an effort to bring the library to the user through features that patrons commonly use. The Virtual Reference Service (VRS) through chat and reference services via videoconferencing are features that derived from this search. Objective: This article aims to outline the implementation process of Virtual Reference Services (SRV) libraries in American universities, particularly those for chat, as well as presenting the successful Brazilian experience. This paper also discusses factors to be considered for implementing virtual reference service via chat for libraries wishing to offer the service. Methodology: The research methodology is based on a theoretical search on international and national literature on the subject. The methodology also includes participant observation. Results: In Brazil the implementation of SRV in some university libraries has occurred and according to these institutions, the SRV is a service that benefits the community and puts the library in line with the demands of information technology and communication. Conclusions: It is concluded that online SRV is appropriate to the reality of university libraries in Brazil, since the institutions that offer the service have positive results from their assessments and believe they are adding value to their library.

Classificação de workflows baseados em web services

Over the last decades changes have occurred in communication within and between enterprises, made easier by technologies suchas E-commerce, Internet, ERP systems and remote meetings and there was a rapid progress in network technology, which has changed the way business is done. A standardized way to offer services over the internet is using web services. Web services are a kind of remote procedure call and are generally used to integrate systems, independent of language, both client and server. It is common to use several web services run in sequence to perform a business process. To this type of process, gives the name of workflow. Thus, Web services are the primary components of workflows. A tool that provides a way of visualizing the behavior of a workflow can assist the administrator and is required. The present work presents the development of a tool that allows the administrator to classify visually services components and evaluate their importance in the final performance of a workflow. As proof of concept we used several virtual servers and computers where each computer has received a set of web services. A proxy was added between each call of workflows collecting relevant information and storing them in a database for later analysis. The analysis was based on Quality of Service parameters

Escolarização de alunos com altas habilidades/superdotação: um apoio virtual

According to current legislation, is part of the Target of Special Education, students with high abilities/giftedness (HA/G). However, it appears that there are few studies on efficiency and effectiveness of diverse pedagogical practice for students with these characteristics. With increasing globalization, are multiplied opportunities for transnational education programs and educational services, particularly through the Internet, increasing the need for information services and accreditation of institutions and educational programs. This study aims to: a) develop a website containing information on high abilities/giftedness; b) evaluate the design of teachers on applicability of the site; c) analyze the contributions posted on the site. Therefore, it was available to the participants of this research produced site. Consisted on the site, among other information, those relating to HA/G indicators. Was sent a questionnaire via the Internet, with nine closed questions and two open, to 2000 teachers, registered in the database Improvement Course in Educational Practices Inclusive conducted by UNESP, under the coordination of Prof. Dr. Vera Lucia Messias Fialho Capellini. Data were considering frequency responses. For the treatment we used the Google Docs. As result Program Observed how teachers are lacking this subject deserves further Top depth. Concerning the site he was Considered by the participants as a support tool to the teacher, Which helps to identify and recognition of Individuals with HA/G and contributes to information, training and practical pedagogical way. This, is expected to Contribute to the dissemination of this issue in society as well as the Possibility of Minimizing the myths about this population, since such myths exist due to the lack of information
