Dynamic Management of Digital Rights for Long-term Preservation:the Expert System Approach

This presentation focuses on the complex issue of managing digital rights for long-term preservation. It describes the strategy and the methodology adopted within the SPAR project (French National Library), which rely on a special kind of knowledge-based system.     

The Concept of Metamorphosis and its Metaphors

The article examines a number of links between the metaphorical uses of the concept of metamorphosis in literature and the various changes of the meaning of the concept that took place at the beginning of the modern scientific age between the 17th and 19th centuries, a period during which the notion of metamorphosis resurfaced in conflict with evolutionist thinking. We present the extent to which the concept of animal metamorphosis, the object of multiple redefinitions over the course of this historical period, became the vector of a very strong metaphorical meaning, which emerged in the literature of the period and survives to this day in certain children’s storybooks belonging to what we term the genre of “realistic fiction”. We intend, from a pedagogical standpoint, to identify which specific attributes of these metaphors exist in those storybooks, and to gauge the extent to which those attributes contradict the scientific characteristics and fictional representations of the concept of metamorphosis.     

Disciplinary Networks and Bounding: Scientific Communication Between Science and Technology Studies and the History of Science

This article examines the communication networks within and between science and technology studies (STS) and the history of science. In particular, journal relatedness data are used to analyze some of the structural features of their disciplinary identities and relationships. The results first show that, although the history of science is more than half a century older than STS, the size of the STS network is more than twice that of the history of science network. Further, while a majority of the journals in the STS network are connected by weak ties, about half of the history of science network consists of strong ties. The history of science network is thus more cohesive than the STS network. The relatively strong cohesion within the history of science network is associated with comparatively high degrees of intra-disciplinary communication, but comparatively weak ties to only a few related disciplines. The analysis also shows that very few members of the history of science cliques are situated on the shortest path between both specialties. Moreover, given the relatively impermeable nature of the history of science network, the latter partially depends on STS to reach some of the neighboring disciplines.     

Is syllable segmentation developmentally constrained by consonant sonority within syllable boundaries in silent reading? Evidence in French children

There is agreement that French typically reading children use syllable‐sized units to segment words. Although the statistical properties of the initial syllables or the clusters within syllable boundaries seem to be crucial for syllable segmentation, little is known about the role of consonant sonority in silent reading. In two experiments that used audio‐visual and visual pseudoword recognition tasks with 300 French typically developing children, we showed a progressive increase in the use of syllable segmentation from the first through fifth years of reading instruction. The children were influenced both by an optimal ‘sonorant coda–obstruent onset’ sonority profile and by the individual position‐dependent consonant sonority within syllable boundaries. Orthographic and phonological statistical properties did not clearly modulate the response patterns. We provide innovative data to help further understand the developmental course of the use of syllable segmentation as determined by sonority. We discuss our results in the light of linguistic principles.     

Academic Mentoring and Dropout Prevention for Students in Math,Science and Technology

In this study, we examined the impact of a new academic mentoring program aimed at preventing student dropout in math, science and technology. The MIRES program entails bimonthly meetings between students entering college and university students completing their undergraduate degree in science and engineering. A randomized pretest-posttest control group design was used to evaluate the program’s short-term impact. At the end of the program, mentees (n = 150) presented significantly higher levels of motivation, a more positive career decision profile and enhanced institutional attachment and social adjustment than students in the control group (n = 157). MIRES mentees also showed success and persistence rates (mainly male participants) that were significantly higher than those of students in the control group.     

Soccer and media in Brazil

This essay analyzes the complex relations between soccer and media in Brazil. Both massmedia and sports arrived in Brazil at the same time, in the late nineteenth century, both associated with the values of modernity in urban centres. It discusses the media coverage of the World Cup and data regarding audiences in particular. The World Cup is considered to be a very important social fact in contemporary Brazilian culture, and since its beginning, the World Cup has been available in Brazil exclusively through the mass media. Since the first international radio transmissions in the late 1930s, Brazil’s matches reached outstanding audience numbers. In the last three World Cups, the share of the total audience for the matches was around 95%, something like 110 million viewers per match, on average. The essay discusses the media’s role in projecting Brazilian football.     

Examining perceived control level and instability as predictors of first-year college students’ academic achievement

The aim of the present study was to examine the intraindividual level and instability of perceived academic control (PC) among first-year college students, and their predictive effects on academic achievement. Two studies were conducted measuring situational (state) PC on different schedules: Study 1 (N = 242) five times over a 6-month period and Study 2 (N = 80) daily over a 2-week period. Consistent across both studies were confirmatory factor analyses and structural equation models demonstrating significant PC instability, as well as negative correlations between intraindividual PC levels (average across measurements) and instability (standard deviation across measurements). Also, in both studies PC level positively predicted subsequent academic achievement, although no significant PC instability first-order effects were found. Both studies revealed a PC level by instability interaction, as students with high-unstable PC typically received poorer grades than high-stable PC students. Study findings highlight the importance of considering both PC level and instability, and identify a previously unknown group of first-year college students at-risk of under-achieving academically – students with high-unstable perceived control.     

Computer-aided Engineering Education and Technical Management

The computer-aided engineering (CAE) system gives an engineer a set of powerful new tools for proper realization of his/her design tasks. Therefore, it is also necessary to accept this methodological development adequately within the engineering curriculum of technical universities in the successful education of the new generation of engineers. CAE methodology influences all areas of an engineer's work and should be accompanied by principal changes in the traditionally used methods of engineering education. But the student's use of computer tools within many engineering disciplines hides the danger of gaining practical skills by means of the computer instead of traditional educational goals concerning the proper understanding of the solution principles of technical problems. Sometimes the students are not able to recognize the significance of, for example, software development problems or engineer workstation organization problems, in view of the main goal of engineering design—to develop a new technical system. To avoid this danger it is necessary to present methods of technical management as an integral part of CAE education. Such orientation has an important role within an engineer's education in the twentieth century.     

The effect of redundant text in multimedia instruction

The purpose of this study was to examine the redundancy effects obtained when spoken information was duplicated in writing during the learning of a multimedia document. Documents consisting of diagrams and spoken information on the development of memory models were presented to three groups of students. In the first group, no written text was presented. In the second, written sentences redundant with the spoken information were progressively presented on the screen while in the third group, these written sentences were presented together. The results show that whatever the type of text presentation (sequential or static), the duplication of information in the written mode led to a substantial impairment in subsequent retention and transfer tests as well as in a task in which the memorization of diagrams was evaluated. This last result supports the hypothesis that the visual channel is overloaded as the cognitive theory of multimedia learning suggests.
