The second half of the twentieth century brought major changes in the society and consequently in the different areas of the sciences. The growing number of universities after the second world war, the post-war industrial growth and later digitalization transformed the sciences present until then, enlarged the scientific community and the number of scientific publications. In the last couple of decades, the creation of web 2.0 brought new possibilities for knowledge co-production, interaction and exchange between all interested parties in research. The goal of this paper is to explore the possibilities for (extended) peer review and quality control on the internet, primarily blogs and social media, which could contribute to the standard peer review process and open the sciences to a wider audience. We are wondering if these processes could also raise the quality in science and lead to the democratization of knowledge production. We argue that changes in science also have an impact in reshaping the society and bringing democratization in knowledge production.  相似文献

The protection against graffiti has become a serious problem in most cities. Unfortunately such form of vandalism does not save the cultural heritage. The use of anti-graffiti coatings is a common treatment that can also temporary protect the surface from degradation due to interactions with the environment. Aspects that have not yet been sufficiently investigated from a metal artefact perspective are whether the presence of the anti-graffiti coating will influence the patina composition and reduce the degree of patina dissolution. Long-term (four years) effects of wax-based anti-graffiti coatings on bare copper sheet and pre-patinated copper exposed to urban atmospheric conditions are presented and discussed in terms of changes in patina dissolution rates, barrier properties and composition. The investigation is based on a multi-analytical approach combining chemical analysis, analytical and electrochemical tools (stereomicroscopy, FTIR, XRD, SEM/EDS, AAS, EIS, colorimetric measurements). Results are believed to provide important information related to the long-term applicability of such coatings to preserve the Cultural Heritage.  相似文献

This paper describes how some innovative methodologies have been designed and employed to support the restoration of the Madonna of Pietranico, a terracotta statue severely damaged in the 2009 earthquake. The statue, fragmented in many pieces, has undergone a complex restoration performed by a multidisciplinary working group. The contribution of digital technologies was planned from the very beginning, since the complexity of this restoration originated the design of innovative procedures for managing the reassembly and restoration process. The Madonna test bed was therefore an example of how technology innovation could be pushed by clear application needs. A first important contribution was the study of the recombination hypothesis of the fragments. This initial phase was performed on digitized 3D models of the statue fragments, with the aim of reducing fragments manipulation, preventing further damages and increasing the capabilities to rehearse and evaluate different reassembly options. The accuracy of the 3D scanned models and the new recombination procedure introduced in this paper allowed to manage this phase in the digital domain with successful results. The digital 3D models were also used to design and produce an innovative supporting structure, constructed with a rapid prototyping device. Another important contribution concerned the study and virtual restoration of the polychrome decoration of the statue; our aim was to reproduce and restore in the virtual 3D domain the very complex original polychrome decoration, on the base of the remaining traces. Consequently, new virtual painting functionalities have been designed on the MeshLab platform (an open-source tool for 3D models visualization and manipulation) for reproducing pictorial decorations over digital 3D models and have been assessed on this specific test bed. This allowed us also to investigate the complexity of the virtual repainting process and to identify further technology enhancements. Finally, computer graphics technologies have been also used to produce a video that tells the story of the restoration.  相似文献

In the present study, the effect of phonological and working memory mechanisms involved in spelling Italian single words was explored in two groups of children matched for grade level: a group of normally hearing children and a group of pre-verbally deaf children, with severe-to-profound hearing loss. Three-syllable and four-syllable familiar words were presented to the two groups for spelling to dictation. Three conditions were used: simple spelling, concurrent articulation, and foot tapping. Verbal digit span was also assessed. Overall, the performance of deaf children tended to be lower compared to hearing children, but not significantly so. Concurrent articulation produced more errors than tapping in both groups. Regression analyses showed that the main predictor in all three tasks was school level, however the proportion of variance explained by this factor was much greater in the dual tasks, in particular in concurrent articulation. Qualitative analyses of errors showed a worse performance of deaf children, with a greater proportion of mixed errors compared to hearing children. They also showed a greater proportion of phonologically plausible errors compared to hearing children, presumably due to their deprived auditory representation, and/or to phonological representations that rely to a large extent on lip reading and kinesthetic and visual perception of articulatory gestures.  相似文献

This text deals with a problem concerning processes of the productive power of knowledge. We draw on the so-called poststructural theories challenging the classical image of thought – as hinged upon a representational logic identifying entities in a rigid sense – when formulating a problem concerning the gap between knowledge and the object of knowledge. More specifically we are looking at this problem in the contexts of sustainable development and childhood, using illustrating examples in order to test the validity of these theoretical accounts. The examples we use range from internationally agreed documents claiming universality concerning environmental protection and childhood to national curricula for the pre-school to a Swedish governmentally produced and distributed TV series called Needle and Stick save the world, addressing the issue of sustainable development. In short, we wish to problematise the rigid positions of the child and the human being in relation to nature.  相似文献

The literature suggests generic workshops on the scholarship of teaching and learning (SoTL) rarely have a lasting impact on teaching. Seeking an alternative approach, academic developers designed a four-stage Collaborative Scholarship Model where they provided individualised SoTL mentoring to academics implementing a teaching innovation. Project outcomes included sustained change to teaching, openness to new ideas, scholarly contributions and peer recognition (through awards, publications or invited presentations). This model had a sustained impact on participants’ teaching and increased research productivity. Although few individuals can be mentored at one time in this labour-intensive model, long-term benefits may still outweigh limitations in scalability.  相似文献
