Foundational aspects of classroom relations: associations between teachers’ immediacy behaviours,classroom democracy,class identification and learning

This study focused on foundational aspects of classroom relations. Specifically, relationships between teachers’ immediacy (interpersonal) behaviours, classroom democracy, identification and learning were considered. Previous work suggests that these variables can be used as a foundation to shape classroom climate, culture and learning outcomes and, by extension, assist educational institutions to achieve their civic mission. This study examined classroom democracy and class identification as variables that mediate the relationship between immediacy behaviours and learning using data collected from 529 students in six institutions of higher learning in Rwanda. Structural equation modeling revealed that classroom democracy mediates the relationship between immediacy behaviours and that classroom democracy and class identification covary substantially. The significant relationships in the final structural model suggest that immediate teachers are likely to have a positive influence on perceptions of classroom democracy, class identification and learning. Based on the growing scholarship of instructional dissent, this study highlights the foundational and strategic aspects underlying these relationships within the context of relating in the classroom and beyond.     

Semi-analytical Monte Carlo simulation of laser-induced fluorescence propagation in an optically participating spray

A semi-analytical Monte Carlo (SMC) simulation was developed to simulate the propagation of laser-induced fluo- rescence (LIF) in an optically participating spray, which simultaneously exhibits spectrally dependent emission, anisotropic scattering, absorption, and re-emission. The SMC simulation is described and then applied to an experimental configuration of a cloud of polydisperse droplets composed of water and sulforhodamine B dye. In the SMC simulation, the collected LIF flux on the remote receptor element is calculated as the global contribution from the emissive source, single, twice, … and nth collision events in any sequence. The effects on the fluorescence photons propagation of spray parameters like the dye concentration, droplets concentration, and droplets size are examined. Three spectral bands representing different optical properties are chosen to analyze the interference of absorption, scattering and re-emission on the detected LIF flux. The obtained spectral LIF flux distribution on the receptor demonstrates a “red shift” phenomenon.     

Towards strategic practices in basic research

Drawing upon the literature of business management, the authors develop an approach to the problems of managing the large research laboratories which have now become more common but which have to exist in the changed climate of the 1980s. The types of managerial problems which arise are classified, the politics of their management analysed and the form in which these problems manifest themselves is discussed. It is concluded that those who have charge of large laboratories must be determined to implement what the authors describe as strategic practice if the laboratories are to function efficiently.

Pourquoi entrer a l'Universite? L'Exemple d'une universite de lettres et sciences humaines

The large number of secondary school graduates entering higher education is transforming the nature of universities, particularly in literature and the humanities, by changing the relative numbers of students enrolled in different academic years. At the same time this influx is accompanied by a significant failure rate in the first academic year, calling into question the efficacy of the university system. A national issue with local repercussions, the struggle against failure in the first year is leading to much heart-searching among the universities, whose staff are trying hard to understand why certain students abandon their studies. The enquiry described in this article reveals the co-existence of two student populations: those who enter university as an active choice and those who do so by default. In the case of the first group, entry to university represents an investment for the future which must be carefully managed. In the second case it is a matter of going into higher education as a faute de mieux solution in an economic context in which work is scarce.     

Search behavior in cats and dogs: Interspecific differences in working memory and spatial cognition

Cats’ and dogs’ search behavior was compared in different problems where an object was visibly moved behind a screen that was then visibly moved to a new position. In Experiments 1 (cats) and 2 (dogs), one group was tested with identical screens and the other group was tested with dissimilar screens. Results showed that in both species, search behavior was based on processing of spatial information rather than on recognition of the visual features of the target screen. Cats and dogs were unable to find the object by inferring its invisible movement. They reached a high level of success only if there was direct perceptual evidence that the object could not be at its initial position. When the position change was indicated by an indirect cue, cats searched more at the object’s initial than final position, whereas dogs searched equally at both positions. Interspecific similarities and differences are interpreted in terms of the requirements for resetting working memory.     

Multidisciplinary graduate training in social research methodology and computer-assisted qualitative data analysis: a hands-on/hands-off course design

Drawing on the experience of training graduate students and researchers in qualitative and mixed-methods analysis since the mid-1990s, the authors reflect on the evolution of a multidisciplinary graduate course developed in a Canadian university since 2007. The hands-on/hands-off course design based on the use of NVivo was developed in parallel with a conceptual and reflexive position on methodology and multidisciplinarity in the context of an action research supported by their institution. This article exposes the four basic components of the course and the constructivist assessment model based on a term-long team analysis of original data created specifically for this purpose. The balance between collective and individual work, in-class and online exchanges, hands-on experience with the software and hands-off reflection is described and compared to recent pedagogical literature on the subject. The interest of this blended approach in fostering the development of the methodological expertise expected from researchers and graduate students, as well as the main issues and challenges facing this type of training in a research environment characterised by new approaches and tools, are discussed.     

Azilian pebbles: an unsolved mystery

The end of the Ice Age (c. 9–8000 BC) in the French Pyrenees and other European areas is characterised by, among other things, the production of enigmatically decorated pebbles. Many theories concerning their function have been put forward. A recent analysis indicates that the decoration is non-random, and may represent some sort of notation.     

Group-Based Emotions: Evidence for Emotion-Performance Relationships in Team Sports

Purpose: In team sports, players have to manage personal interests and group goals, emphasizing intricacies between personal and social identities. The focus of this article was to examine the effect of identity mechanisms on appraisal processes, based on the following research question: Does the level of self-abstraction (low [personal identity] versus high [social identity]) lead to group-based emotions and influence performances? Method: An experimental design was used in which the level of self-abstraction was manipulated through the induction of a self- versus a team-oriented goal. Thirty elite male rugby players (M_age = 19.06, SD = 0.78, randomly split) participated in a match reproducing conditions similar to those of official games. Individual and perceived team-level emotions and performance were measured 17 times during the match. Results: Linear Mixed Effects models showed that a high level of self-abstraction: (a) led to more positive and less negative individual (variances explained: 52% and 46%) and perceived team-referent (variances explained: 57% and 40%) emotions; (b) reduced the correlation of team-referent emotions with individual ones; and (c) positively influenced team and individual performances (variances explained: 50% and 19%). Moreover, after controlling for potential effects of the level of self-abstraction, only positive team-referent emotions influenced performance. Conclusions: This study is the first to experimentally manipulate athletes’ social identity to examine group-based emotions in sport. Challenging the usual intrapersonal approaches, these findings suggested that social identity and its association with team-referent emotions could be one of the key dimensions of emotion-performance relationships in team sports.
