Usagers & Recherche d'Information

La recherche d'information est confrontée à une variété de plus en plus importante tant en termes d'usagers, de tâches à remplir, d'outils.... Face à cette hétérogénéité de nombreux travaux, s'attachent à améliorer la recherche d'information par le biais d'approches adaptatives, de systèmes de recommandation... Mes travaux s'inscrivent dans ce cadre et apportent un éclairage essentiellement porté sur l'usager et ses activités et plus particulièrement sur la recherche d'information. Les résultats correspondent à 3 angles d'investigation nous permettant d'aborder cette problématique de l'hétérogénéité en Recherche d'Information

Usability analysis of contending electronic health record systems

In this paper, we report measured usability of two leading EHR systems during procurement. A total of 18 users participated in paired-usability testing of three scenarios: ordering and managing medications by an outpatient physician, medicine administration by an inpatient nurse and scheduling of appointments by nursing staff. Data for audio, screen capture, satisfaction rating, task success and errors made was collected during testing. We found a clear difference between the systems for percentage of successfully completed tasks, two different satisfaction measures and perceived learnability when looking at the results over all scenarios. We conclude that usability should be evaluated during procurement and the difference in usability between systems could be revealed even with fewer measures than were used in our study. © 2019 American Psychological Association Inc.

Root, Tuber and Banana Food System Innovations

This open access book describes recent innovations in food systems based on root, tuber and banana crops in developing countries. These innovations respond to many of the challenges facing these vital crops, linked to their vegetative seed and bulky and perishable produce. The innovations create value, food, jobs and new sources of income while improving the wellbeing and quality of life of their users. Women are often key players in the production, processing and marketing of roots, tubers and bananas, so successful innovation needs to consider gender. These crops and their value chains have long been neglected by research and development, hence this book contributes to filling in the gap. The book features many outcomes of the CGIAR Research Program in Roots, Tubers and Banana (RTB), which operated from 2012-21, encompassing many tropical countries, academic and industry partners, multiple crops, and major initiatives. It describes the successful innovation model developed by RTB that brings together diverse partners and organizations, to create value for the end users and to generate positive economic and social outcomes. RTB has accelerated the scaling of innovations to reach many end users cost effectively. Though most of the book’s examples and insights are from Africa, they can be applied worldwide. The book will be useful for decision makers designing policies to scale up agricultural solutions, for researchers and extension specialists seeking practical ideas, and for scholars of innovation

Proceedings of the Eighth Italian Conference on Computational Linguistics CliC-it 2021

The eighth edition of the Italian Conference on Computational Linguistics (CLiC-it 2021) was held at Università degli Studi di Milano-Bicocca from 26th to 28th January 2022. After the edition of 2020, which was held in fully virtual mode due to the health emergency related to Covid-19, CLiC-it 2021 represented the first moment for the Italian research community of Computational Linguistics to meet in person after more than one year of full/partial lockdown

Proceedings of the 10th International Conference on Ecological Informatics: translating ecological data into knowledge and decisions in a rapidly changing world: ICEI 2018

The Conference Proceedings are an impressive display of the current scope of Ecological Informatics. Whilst Data Management, Analysis, Synthesis and Forecasting have been lasting popular themes over the past nine biannual ICEI conferences, ICEI 2018 addresses distinctively novel developments in Data Acquisition enabled by cutting edge in situ and remote sensing technology. The here presented ICEI 2018 abstracts captures well current trends and challenges of Ecological Informatics towards: • regional, continental and global sharing of ecological data, • thorough integration of complementing monitoring technologies including DNA-barcoding, • sophisticated pattern recognition by deep learning, • advanced exploration of valuable information in ‘big data’ by means of machine learning and process modelling, • decision-informing solutions for biodiversity conservation and sustainable ecosystem management in light of global changes

Evidence-based eLearning Design: Develop and Trial a Prototype Software Instrument for Evaluating the Quality of eLearning Design Within a Framework of Cognitive Load Theory

A major research direction within higher education in Australia and internationally is the evaluation of learning design quality and the extent to which the design–teaching–learning–evaluation cycle is evidence based. The quest for increased evidence-based learning design, which has been influenced by evidence-based medical research standards, is driven by its link to improved learning outcomes, higher learner engagement levels and lower attrition rates. Cognitive Load Theory (CLT) has risen to prominence over the past three decades as an evidence-based framework for informing instructional design in traditional, blended and multimedia learning environments. CLT approaches learning from the perspective of engaging specific strategies to manage the loads imposed on a limited working memory in order to form and automate long-term memory schemas. CLT operates on the premise that optimal learning conditions may be obtained by aligning pedagogical strategies with the structure and functions of human cognitive architecture and the individual learner’s prior knowledge. CLT has contributed a suite of strategies derived from a unified model of human cognitive architecture and validated through randomised controlled trial (RCT) experiments as exerting strengthening effects on learning, thus suiting the CLT framework for use as an evidence-based standard in this study. Up to this point, a single digital system has not yet been developed for managing, monitoring and evaluating the implementation and impact of CLT strategies at scale. The key contribution of this study is a new prototype software instrument called Cognitive Load Evaluation Management System (CLEMS) that addresses this issue and also provides a model for its implementation. CLEMS is underpinned by a personalised model of teacher–learner interactions defined as mediative–adaptive in nature that includes diagnostic conversations (DCs) for identifying barriers to learning, interventions called Nodes of Expertise (NOEs) for advancing learners to new levels of understanding of complex knowledge, and validation conversations (VCs) for evaluating learner progress. In addition, the heutagogical or self-directed learning capability of learners, including motivation, has been brought to the fore as a significant factor contributing to schema automation. A qualitative Design-based Research (DBR) methodological approach was used to develop CLEMS, which emerged over three research iterations through the synthesis of literature review findings and empirical data from expert focus groups. Emergent data was continuously triangulated between research iterations and ongoing literature reviews to refine the design and development of CLEMS from a theoretical model to an operational digital prototype. The conceptual framework of the study has been derived from Critical Realism (CR) which posits an ontological–epistemological view of reality that is stratified and multi-mechanistic, thus aligning with the complex nature of authentic learning environments as well as the multi-faceted model of human cognitive architecture contributed by CLT. The implications of the study have been discussed with reference to stakeholders including teachers, learners and educational institutions. Recommendations for future research include the ongoing development of CLEMS for the systematic implementation of CLT strategies at scale.Thesis (Ph.D.) -- University of Adelaide, School of Education, 202
