Comparative ergonomic workflow and user experience analysis of MRI versus fluoroscopy-guided vascular interventions: an iliac angioplasty exemplar ca…
2014
A methodological framework is introduced to assess and compare a conventional fluoroscopy protocol for peripheral angioplasty with a new magnetic resonant imaging (MRI)-guided protocol. Different scenarios were considered during interventions on a perfused arterial phantom with regard to time-based and cognitive task analysis, user experience and ergonomics. Three clinicians with different expertise performed a total of 43 simulated common iliac angioplasties (9 fluoroscopic, 34 MRI-guided) in two blocks of sessions. Six different configurations for MRI guidance were tested in the first block. Four of them were evaluated in the second block and compared to the fluoroscopy protocol. Relevant…
Teaching Methods in a Health and Social Informatics Master Program
2019
Education is an important contribution to the digital transformation in society. In health care services, there is a need to combine knowledge in health science and information-and communication technologies. At the University of Agder in Norway, there is a Master's Program in Health and Social Informatics targeting students with health educational background. This paper shares the experiences on methods for teaching basic information-and communication technology to this student group. A quantitative study was made to evaluate the pedagogical methods and the organization of a technical master course with respondents from the last two classes. The experiences on the course execution and the …
Cross‐lagged associations between kindergarten teachers' causal attributions and children's task motivation and performance in reading
2009
The present study investigated whether kindergarten teachers' causal attributions would predict children's reading‐related task motivation and performance, or whether it is rather children's motivation and performance that contribute to teachers' causal attributions. To investigate this, 69 children (five to six years old at baseline) and their teachers were examined twice during the kindergarten year. Teachers filled in a questionnaire measuring their causal attributions twice during the kindergarten year. Information about the children's reading‐related task motivation and performance was gathered at the beginning of and at the end of the kindergarten year. The results showed that the hig…
Multiple Authentic Project-Based Experiences and Persistent Learning?
2019
This work-in-progress paper in the research category investigates students’ experiences of learning over two project-based courses, of which the first is taken during bachelor studies and the second is taken during master studies. The research goal was to explore if and how the first project experience was considered beneficial to the latter. A pilot interview was conducted and analyzed for qualitatively different themes. Transformative learning theory (TLT) is introduced as the theoretical framework because of its focus on persistent learning originating in transformations in meaning perspectives. The results are discussed in the context of TLT, and they inform curriculum design and resear…
Evidence against preserved syntactic comprehension in healthy aging.
2018
We investigated age-related differences in syntactic comprehension in young and older adults. Most previous research found no evidence of age-related decline in syntactic processing. We investigated elementary syntactic comprehension of minimal sentences (e.g., I cook), minimizing the influence of working memory. We also investigated the contribution of semantic processing by comparing sentences containing real verbs (e.g., I cook) versus pseudoverbs (e.g., I spuff). We measured the speed and accuracy of detecting syntactic agreement errors (e.g., I cooks, I spuffs). We found that older adults were slower and less accurate than younger adults in detecting syntactic agreement errors for both…
Peer-assessment using test exams in a Sakai-based e-learning platform
2021
We report our work on the implementation of a learning innovation based on the combination of peer-assessment and formative learning. The methodology consists on the students themselves to propose, review and select questions for the subsequent creation of a "multiple choice" exam to assess their progress. This learning innovation is carried out with a minimum intervention from the lecturer by using testing tools from the Sakai-based e-learning platform of our institution in combination with several software functions that have been created to automate the aggregation and processing of the students’ contributions. According to the feedback collected from the students, these learning tasks h…
Prediction of the difficulty level in a standardized reading comprehension test: contributions from cognitive psychology and psychometrics
2013
This research seeks to identify possible predictors of the difficulty level of reading comprehension items used in a standardized psychometric test for university admission. Several potential predictors of difficulty were proposed, namely, propositional density, negations, grammatical structure, vocabulary difficulty, presence of enhancement elements (words highlighted typographically), item abstraction level and degree of similarity between correct option and relevant text to resolve the item. By Linear Logistic Test Model (Fisher, 1973) it was found that the number of propositions, the syntactic structure, and fundamentally, the presence of difficult words contributed to the prediction of…
Early-design improvement of human reliability in an experimental facility: A combined approach and application on SPES
2019
Abstract SPES (Selective Production of Exotic Species) is a second-generation Isotope Separation On-Line (ISOL) facility for advanced nuclear physics applications, currently under construction at INFN (National Institute of Nuclear Physics) of Legnaro, Italy. Despite the potentially important safety implications of human errors for ISOL facilities, only a limited number of studies addressing this issue have been performed worldwide. This paper tries to address this need by means of an integrated approach of Hierarchical Task Analysis (HTA) and three human error quantification methods: HEART (in an enhanced version), SPAR-H, and CREAM. The application of multiple Human Reliability Analysis (…
A social humanoid robot as a playfellow for vocabulary enhancement
2018
We introduce a system that exploits a Pepper humanoid robot acting as a playfellow in a word-play game. The robot can play a portmanteau game by directly interacting with children, and it exploits a conversation engine, a portmanteau creation engine, and a definition engine. The humanoid can play the role of either an answerer or a generator of new words.
Developing motor planning over ages
2009
International audience; Few studies have explored the development of response selection processes in children in the case of object manipulation. In the current research, we studied the end-state comfort effect, the tendency to ensure a comfortable position at the end rather than at the beginning of simple object manipulation tasks. We used two versions of the unimanual bar transport task. In Experiment 1, only 10-year-olds reached the same level of sensitivity to end-state comfort as adults, and 8-year-olds were less efficient than 6-year-olds. In each age group, children’s sensitivity did not increase during a session: i.e., either clearly showed the sensitivity or showed no sensitivity a…
