Eye-tracking the Effects of Representation on Students' Problem Solving Approaches
2017
This study used an eye-tracking method to explore students’ approaches to solving the same task in different representations and the differences between students who answered correctly and those who answered incorrectly when solving the problems. Thirty-one upper secondary students took part in the study. According to the results of this study, the representation has a slight effect on students’ problem solving processes. Students with the incorrect answers paid more attention to the parts of the tasks with information irrelevant to determining the solution to the task. peerReviewed
Fast track -hoitomallin taloudellinen arviointi Keski-Suomen sairaanhoitopiirissä
2010
Keski-Suomen sairaanhoitopiirissä gastrokirurgian kehitystyössä on viime vuosina keskitytty yhtenä osa-alueena perioperatiivisen hoidon ja potilasturvallisuuden parantamiseen sekä erityisesti fast track – hoitomalliin. Fast track -hoitomallin tavoite on optimoida potilaiden postoperatiivista toipumista käyttämällä mini-invasiivisia leikkausmenetelmiä,uusia anestesiamenetelmiä ja tehostamalla perioperatiivista hoitotyötä sekä vähentää komplikaatioiden syntymistä, sairaalassa oloa sekä kustannuksia suuren leikkauksen jälkeen. Tutkimuksen tarkoituksena on selvittää minkälaisia taloudellisia vaikutuksia fast track -hoitomallin käyttöönotolla on ollut sekä onko hoitomallin avulla saavutettu kust…
Robust Selective Stereo SLAM without Loop Closure and Bundle Adjustment
2013
This paper presents a novel stereo SLAM framework, where a robust loop chain matching scheme for tracking keypoints is combined with an effective frame selection strategy. The proposed approach, referred to as selective SLAM (SSLAM), relies on the observation that the error in the pose estimation propagates from the uncertainty of the three-dimensional points. This is higher for distant points, corresponding to matches with low temporal flow disparity in the images. Comparative results based on the reference KITTI evaluation framework show that SSLAM is effective and can be implemented efficiently, as it does not require any loop closure or bundle adjustment.
Gender-Typed Sport Practice, Physical Self-Perceptions, and Performance-Related Emotions in Adolescent Girls
2020
Youth sport experience provides opportunities for physical, personal, and social development in youngsters. Sport is a social system in which socially constructed gender differences and stereotypes are incorporated, and specific sport activities are often perceived as gender characterized. The objective of this study was to examine the relationship between some salient physical and emotional self-perceptions and the type of sport practiced. A sample of 261 female athletes, aged 14–21 years (Mage = 15.59, SD = 2.00), practicing different sports, categorized as feminine (e.g., artistic and rhythmic gymnastics), masculine (e.g., soccer and rugby), or neutral (e.g., track and field and tennis),…
TRANS-FUSIMO: preliminary in-vivo animal results of MR-guided focused ultrasound of liver under respiratory motion
2019
Purpose: Treating liver tumors using Focused Ultrasound (FUS) is a great challenge. Prior to human applications, an in-vivo animal trial using the TRANS-FUSIMO treatment system (TTS) is ongoing in order to evaluate the safety and the technical efficacy and efficiency of generating predefined necrotic lesions. Methods and Materials: The trial includes a crossbred porcine model of thirty large white swine (all females; 55-85Kg) that will be treated using the TTS under general anaesthesia with intubation. All treatments haven been performed under ventilator-controlled breathing and using an improved non-clinical prototype FUS transducer integrated with a 1,5T MRI unit; a set of interventional …
Il Fast Track nelle fratture di femore può davvero favorire risultati clinici migliori?
2016
Le attuali linee guida raccomandano di effettuare il trattamento chirurgico di stabilizzazione o sosti- tuzione protesica entro 24-48 ore dall’accesso ospedaliero, al ne di migliorare il risultato funziona- le, ridurre il rischio di mortalità, la degenza ospedaliera e le complicazioni post-operatorie. Tuttavia, la mancanza di studi randomizzati rappresenta un importantissimo limite scienti co dal momento che ad oggi la migliore evidenza scienti ca sul timing chirurgico nelle fratture di collo femore si basa esclusivamente su studi prospettici e retrospettivi. In questo articolo, viene descritto il percorso ospedaliero per il trattamento delle fratture del collo del femore nel paziente anzia…
An interactional ‘live eye tracking’ study in autism spectrum disorder : combining qualitative and quantitative approaches in the study of gaze
2017
Recent studies on gaze behaviours in individuals with autism spectrum disorder (ASD) have utilised “live eye tracking.” Such research has focused on generating quantitative eye tracking measurements, which provide limited (if any) qualitative contextual details of the actual interactions in which gaze occurs. This article presents a novel methodological approach that combines live eye tracking with qualitative interaction analysis, multimodally informed conversation analysis. Drawing on eye tracking and wide-angle video recordings, this combination renders visible some of the functions, or what gaze “does,” in interactional situations. The participants include three children with ASD and th…
Itsensä mittaamisen teknologioiden hyödyntäminen yksilön terveyden tukena
2017
Tässä kandidaatintutkielmassa tutkittiin itsensä mittaamisen teknologioiden hyödyntämistä yksilön terveyden tukena. Tutkielman toteutustapana oli kirjallisuuskatsaus, joten tutkielman tulokset perustuvat aiemmin julkaistuihin tutkimuksiin ja tieteellisiin julkaisuihin. Kirjallisuudesta etsittiin vastausta tutkimuskysymykseen: kuinka itsensä mittaamisen teknologioita voidaan hyödyntää yksilön terveyden tukena? Liikalihavuus, sydän- ja verisuonitaudit, fyysinen inaktiivisuus sekä mielenterveysongelmat ovat maailmanlaajuisia terveysongelmia. Hyvinvointi ja terveys ovat monimuotoisia käsitteitä, mutta terveys voidaan jakaa kolmeen osa-alueeseen: fyysiseen, psyykkiseen sekä sosiaaliseen terveyte…
Simple Configuration Effects on Eye Movements in Horizontal Scanning Tasks
2015
When reading text, observers alternate periods of stable gaze (fixations) and shifts of gaze (saccades). An important debate in the literature concerns the processes that drive the control of these eye movements. Past studies using strings of letters rather than meaningful text ('z-reading') suggest that eye movement control during reading is, to a large extent, controlled by low-level image properties. These studies, however, have failed to take into account perceptual grouping processes that could drive these low-level effects. We here study the role of various grouping factors in horizontal scanning eye movements, and compare these to reading meaningful text. The results show that sequen…
Early attraction in temporally controlled sight reading of music
2018
A music reader has to “look ahead” from the notes currently being played—this has usually been called the Eye-Hand Span. Given the restrictions on processing time due to tempo and meter, the Early Attraction Hypothesis suggests that sight readers are likely to locally increase the span of looking ahead in the face of complex upcoming symbols (or symbol relationships). We argue that such stimulus-driven effects on looking ahead are best studied using a measure of Eye-Time Span (ETS) which redefines looking ahead as the metrical distance between the position of a fixation in the score and another position that corresponds to the point of metrical time at fixation onset. In two experiments of …
