Facilitating Collaboration

2017

This article explores the potential synergy between computer-supported collaborative learning (CSCL) and collaboration engineering (CE). Both areas pursue the goal of understanding how to manage interactions in collaborative groups to achieve shared understanding, reduce process losses, and improve performance. By analyzing the research in the two areas, the authors identify several topics where exchange of research findings would be of mutual benefit. For example, research on CE can inform collaboration script research on reducing learners' cognitive load, providing sufficient guidance on the use of tools, and specifying the instructor role during the collaborative learning process. Simila…

SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT

2011

8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files for the JaSIM environment that performs the simulation. These files deserve the representation of the virtual environment in which the simulation is …

Tracing discursive processes of shared knowledge construction in a technology-enhanced higher education setting

2013

This study focused on combining both the group- and individual-level analyses in studying a collaborative activity in technology-enhanced interactions in a higher education setting. The aim was to make visible, with empirical examples, the quality of the students' web-based discussions and trace the route for shared understanding. By quantifying various communicative functions, the analysis provided general knowledge on the quality and purpose of the discussion in the group and highlighted the different functional positions each student had within the group. However, only a detailed interpretative analysis of the relationships between specific thematic contents, communicative functions, and…

Big Data Analytics Affordances for Social Innovation: A Theoretical Framework

2021

This paper proposes a theoretical framework to identify the mechanisms by which actors perceive the affordances of big data analytics (BDA) and how institutional voids and supports enable or hinder the actualisation of those perceived affordances. In doing so, we contribute to identifying the missing link needed to understand the social innovation process in relation to BDA. The framework paves the ground towards understanding the institutionalization process of social innovation and its implications for research and practice.

Adoption and use of mobile technologies for learning among smallholder farmer communities in Uganda

2016

Mobile learning (mLeaming) in formal education is getting wide spread but little is known about how to adopt mLeaming in non-formal contexts among smallholder farmer communities, who constitute the majority in most African states. These rely on agriculture, yet their livelihoods are affected by immense changes in seasons. Smallholder farmers' access to mobile phones can act as bridges in supporting learning for secure livelihoods. Using the Unified Theory of Acceptance and Use of Technology (UTAUT), we have conducted multiple case studies of the Community Knowledge Worker project in Uganda. The intention was to analyse mobile learning adoption and use practices among farmers. Based on our f…

The Ph.D.-candidate as an information literate resource: developing research support and information literacy skills in an informal setting

2013

Published version of an article in the journal Liber Quarterly, Open Access This article aims to suggest a new way of developing research support for PhD-candidates. Previous research on the field of research support is greatly focused on librarians’ competencies and how to assist researchers with what they lack in information literacy (IL) skills. There is little focus on collaboration with researchers to achieve a mutual learning outcome in regard to developing research support and IL skills. A socio-cultural view on IL indicates that IL skills are developed in a context, and therefore are situated. A high level of IL in one situation could be regarded as insufficient in another. Therefor…

Image Quality Assessment Based on Intrinsic Mode Function Coefficients Modeling

2011

Reduced reference image quality assessment (RRIQA) methods aim to assess the quality of a perceived image with only a reduced cue from its original version, called ”reference image”. The powerful advantage of RR methods is their ”General-purpose”. However, most introduced RR methods are built upon a non-adaptive transform models. This can limit the scope of RR methods to a small number of distortion types. In this work, we propose a bi-dimensional empirical mode decomposition-based RRIQA method. First, we decompose both, reference and distorted images, into Intrinsic Mode Functions (IMF), then we use the Generalized Gaussian Density (GGD) to model IMF coefficients. Finally, the distortion m…

A New Image Distortion Measure Based on Natural Scene Statistics Modeling

2012

In the field of Image Quality Assessment (IQA), this paper examines a Reduced Reference (RRIQA) measure based on the bi-dimensional empirical mode decomposition. The proposed measure belongs to Natural Scene Statistics (NSS) modeling approaches. First, the reference image is decomposed into Intrinsic Mode Functions (IMF); the authors then use the Generalized Gaussian Density (GGD) to model IMF coefficients distribution. At the receiver side, the same number of IMF is computed on the distorted image, and then the quality assessment is done by fitting error between the IMF coefficients histogram of the distorted image and the GGD estimate of IMF coefficients of the reference image, using the …

The hidden side of adverbs

2018

This paper will address the predicative nature of manner adverb(ial)s and of three types of sentence adverbs (subject-oriented, modal, and evaluative) in Italian. Predication often becomes overt by means of morphological correlates. Is it possible to find any such evidence with invariable adverbs? To unveil their predicative nature, a procedure will be suggested in which two sentences, one with a -mente adverb, the other with its cognate adjective (a) share the content morphemes (identity of the signifiant) and (b) entail each other (identity of the signifié as regards semantic roles). A number of such pairs will be discussed, examples of which include: Intelligentemente, Leo intervenne ‘Cl…
