Transparencia presupuestaria en los gobiernos municipales de Brasil por medio de internet: el caso de Piracicaba São Paulo

This article seeks to assess the extent to which the municipality of Piracicaba (in the Brazilian state of São Paulo) has practiced Municipal Budgetary Transparency in Internet (TOM Web), as conceptualized by Pires (2011). The TOM Web is based on definitions used by the IMF and the OECD, and the characteristics of the Brazilian institutional and legal reality.

A video-based biometric authentication for e-learning web applications

In the last years there was an exponential growth in the offering of Web-enabled distance courses and in the number of enrolments in corporate and higher education using this modality. However, the lack of efficient mechanisms that assures user authentication in this sort of environment, in the system login as well as throughout his session, has been pointed out as a serious deficiency. Some studies have been led about possible biometric applications for web authentication. However, password based authentication still prevails. With the popularization of biometric enabled devices and resultant fall of prices for the collection of biometric traits, biometrics is reconsidered as a secure remote authentication form for web applications. In this work, the face recognition accuracy, captured on-line by a webcam in Internet environment, is investigated, simulating the natural interaction of a person in the context of a distance course environment. Partial results show that this technique can be successfully applied to confirm the presence of users throughout the course attendance in an educational distance course. An efficient client/server architecture is also proposed. © 2009 Springer Berlin Heidelberg.

Crime, medo e percepções de insegurança

O artigo é produto de três pesquisas de vitimização realizadas em Marília/SP, entre os anos de 2001 e 2008, com o objetivo de conhecer a dinâmica do crime sob a ótica da vítima real (objetiva) e captar os sentimentos de medo do risco “potencial” da população (vítima ou não). O primeiro caso – vítima real – constitui um instrumento auxiliar ao desenvolvimento de programas de prevenção mais eficazes por abranger, inclusive, os crimes subnotificados. De modo geral, os resultados contribuirão para a compreensão de alguns aspectos da dinâmica criminal, da relação entre a polícia e a comunidade, da percepção do medo e da sensação de (in)segurança.

Fóruns no ambiente Teleduc: reflexões sobre o papel dos mediadores e estratégias de gerenciamento de debates

Online discussion forums have been widely used in internet-mediated courses and blended courses. In these learning contexts, the mediator's (or tutor's) role in supporting successful learning is of considerable importance. Firstly, the present article discusses some studies in which the mediator's role in online learning environments is emphasized. Secondly, we use this discussion to support our qualitative case-study analysis, in which we investigated mediators' debate-management strategies in TelEduc virtual forums. Lastly, we propose a reflective framework about management strategies in forums in virtual learning platforms.

In-process thermal damage detection in grinding with monitoring via Internet

This work aims the development of a dedicated system for detection of burning in surface grinding process, where the process will constantly be monitored through the acoustic emission and electric power of the induction motor drive. Acquired by an analog-digital converter, algorithms process the signals and a control signal is generated to inform the operator or interrupt the process in case of burning occurrence. Moreover, the system makes possible the process monitoring via Internet. Additionally, a comparative study between parameters DPO and FKS is carried through. In the experimental work one type of. steel (ABNT-1020 annealed) and one type of grinding wheel referred to as TARGA, model ART 3TG80.3 NVHB, were employed.

Automatic system for thermal damage detection in manufacturing process with Internet monitoring

This work involved the development of a smart system dedicated to surface burning detection in the grinding process through constant monitoring of the process by acoustic emission and electrical power signals. A program in Visual Basic® for Windows® was developed, which collects the signals through an analog-digital converter and further processes them using burning detection algorithms already known. Three other parameters are proposed here and a comparative study carried out. When burning occurs, the newly developed software program sends a control signal warning the operator or interrupting the process, and delivers process information via the Internet. Parallel to this, the user can also interfere in the process via Internet, changing parameters and/or monitoring the grinding process. The findings of a comparative study of the various parameters are also discussed here. Copyright © 2006 by ABCM.

Potential scenarios for Internet use in the mathematics classroom

Research on the influence of multiple representations in mathematics education gained new momentum when personal computers and software started to become available in the mid-1980s. It became much easier for students who were not fond of algebraic representations to work with concepts such as function using graphs or tables. Research on how students use such software showed that they shaped the tools to their own needs, resulting in an intershaping relationship in which tools shape the way students know at the same time the students shape the tools and influence the design of the next generation of tools. This kind of research led to the theoretical perspective presented in this paper: knowledge is constructed by collectives of humans-with-media. In this paper, I will discuss how media have shaped the notions of problem and knowledge, and a parallel will be developed between the way that software has brought new possibilities to mathematics education and the changes that the Internet may bring to mathematics education. This paper is, therefore, a discussion about the future of mathematics education. Potential scenarios for the future of mathematics education, if the Internet becomes accepted in the classroom, will be discussed. © FIZ Karlsruhe 2009.
