We present our recent efforts in the digital preservation of a set of baroque sculptures made by Antônio Francisco Lisboa, known as O. Aleijadinho, which is an important American baroque artist. The set was made in the beginning of the xix century and is composed of 12 near real sized sculptures, hand-carved in soapstone. These sculptures represent 12 of the 16 prophets from the Holy Bible and are part of a UNESCO World Heritage Site. Our group has been collaborating with UNESCO in a project that aims to preserve all these statues. We hereby present our initial efforts, consisting of the 3D digital preservation of the Prophet Joel sculpture. We developed a complete 3D digital preservation pipeline composed of four main stages: data acquisition, 3D reconstruction, texture generation and 3D model visualization. By evaluating our results in this first sculpture, we discuss the improvements we conceived before applying our pipeline in the remaining ones. Finally, we present the 3D model of the Prophet which registers the sculpture's current state and will be used in restoration, research and educational activities. We believe this contribution may be useful to guide further research on similar scenarios, showing how to avoid some practical mistakes and achieve good results. 相似文献

This paper describes an integrated authoring environment, AIDA (Ambiente Integrado de Desenvolvimento de Aplicações educacionais). It is an open tool, giving the author a high degree of freedom both in package characteristics and design methodologies used. This environment integrates several modules. The core of the design module is a prototyping tool, allowing the creation of evolutionary prototypes. These prototypes can include several types of multimedia components and can be used as part of the final package. The AIDA environment also includes other options that support evaluation, learning materials re-use, communication between authoring team members and translation and cultural adaptation of packages to work in different environments. An experimental version of this authoring environment was implemented and the results of its evaluation are encouraging. In this paper we also present an example of a package created with the AIDA authoring environment. 相似文献

This article traces the ways in which the British suffragette Emily Wilding Davison was represented in national newspapers between 1913—the year she died—and 2013, the centenary of her death. We identify three key discourses through which Davison has been represented in four British newspapers throughout the twentieth century and into the twenty-first: delegitimisation, recuperation and trivialisation. In doing so, this paper provides original insights into the ways that the fight for women’s rights has been figured in different historical moments. A key argument is that over time, Davison’s militant actions—once cast as those of a hysterical lunatic—have slowly come to be recuperated and legitimised as part of the story of British democracy. However, this discursive shift cannot be straightforwardly celebrated as a progressive move in representations of women’s movements, as Davison is frequently invoked to delegitimise contemporary feminism. Our analysis charts the extent to which Davison has been visible (or not) in newspapers through different historical periods; the specific ways in which Davison’s image was transformed along with broader changes in women’s status; and it considers the political implications of these (in)visibilities and representations for contemporary feminism. 相似文献

The objective of this study was to check attitudes towards mathematics and to analyse if there are differences in attitudes that could be attributed to the type of school, gender, grade, age, the frequency in which mathematical problems were understood, the amount of days dedicated to the study of mathematics, school failure, whether help on the completion of homework was offered and to the self-perception of mathematical performance. A total of 209 students of the 3rd and 4th Grades of basic education in the private school system in Campinas, Sao Paulo, Brazil, were surveyed. They responded to an attitude towards mathematics scale and to a questionnaire for their characterisation, during school hours and in the absence of their mathematics teacher. The average figure on the attitudes scale was 52.718, with a standard deviation of 11.837. Significant statistical differences were found (alpha = 0.05) in the attitudes according to the type of school, the frequency in which the subjects understood the mathematical problems solved in the classroom, grade, age and to the self-perception of mathematical performance. 相似文献
