Professional vision of Grade 1 teachers experiencing different levels of work-related stress

2022

This study explored teachers' professional vision by examining how teachers experiencing low, moderate and high work-related stress reason their eye-tracking recordings in terms of description, explanation and prediction. A qualitative analysis of retrospective think-aloud interviews with 24 Grade 1 teachers showed that teachers predominantly used description in their reasoning, while explanation and prediction were less frequent. The description mainly focused on teacher information/elaboration and classroom management/behaviour. Teachers with moderate stress utilised self-reflection most frequently, whereas teachers with high stress utilised it the least. The results suggest that the leve…

Q fever: a new ocular manifestation

2011

P Udaondo1,3, S Garcia-Delpech1,2, D Salom1,2, M Garcia-Pous1, M Diaz-Llopis1,21Department of Ophthalmology, Nuevo Hospital Universitario y Politecnico La Fe, Valencia, Spain; 2Faculty of Medicine, Universitat de València, Valencia, Spain; 3Universidad Cardenal Herrera CEU, Valencia, SpainAbstract: Q Fever is a zoonosis caused by Coxiella burnetii. Ocular manifestations are rare in this infection. We describe the case of a man complaining of an intense retro-orbital headache, fever, arthralgia, and bilateral loss of vision, who showed an anterior uveitis accompanied by exudative bilateral inferior retinal detachment and optic disk edema. At the beginning, a Vogt–Koyanag…

The ocular manifestations in IBD screening (OMIS) questionnaire: pilot study on detection of ocular involvement in inflammatory bowel diseases.

2020

Purpose: To assess the usefulness of a dedicated questionnaire for patients with inflammatory bowel diseases (IBD) treated with biological drugs for the detection of ocular extraintestinal manifestations (EIMs). IBD can cause extraintestinal symptoms including ocular complaints which are frequently ignored and may be associated with significant morbidity, including blindness. Methods: We developed a questionnaire, named Ocular Manifestations in IBD Screening (OMIS) questionnaire, after agreement between gastroenterologists and ophthalmologists. The questionnaire was administered by a non-ophthalmologist physician to 96 IBD patients treated with biological drugs. Results: 35 patients (36.5%)…

Modeling visual sampling on in-car displays: The challenge of predicting safety-critical lapses of control

2015

In this article, we study how drivers interact with in-car interfaces, particularly by focusing on understanding driver in-car glance behavior when multitasking while driving. The work focuses on using an in-car touch screen to find a target item from a large number of unordered visual items spread across multiple screens. We first describe a cognitive model that aims to represent a driver?s visual sampling strategy when interacting with an in-car display. The proposed strategy assumes that drivers are aware of the passage of time during the search task; they try to adjust their glances at the display to a time limit, after which they switch back to the driving task; and they adjust their t…

Tolerance towards resident intestinal flora in mice is abrogated in experimental colitis and restored by treatment with interleukin-10 or antibodies …

1996

There is now increasing evidence that hyperresponsiveness towards intestinal flora is a crucial event in the pathogenesis of inflammatory bowel disease (IBD). In support of this hypothesis, we recently described in humans that tolerance exists towards indigenous intestinal flora but is broken in active IBD lesions. In the present study, we have attempted to transfer this model into mice from different genetic backgrounds (BALB/c, SJL/J, C3H/HeJ). We found that mononuclear cells from spleen, small bowel and large bowel of mice do not proliferate, i.e. are tolerant when exposed to bacterial sonicates derived from autologous intestine (BsA) but do proliferate, i.e. are immune when exposed to b…

Semantic and topological classification of images in magnetically guided capsule endoscopy

2012

International audience; Magnetically-guided capsule endoscopy (MGCE) is a nascent technology with the goal to allow the steering of a capsule endoscope inside a water filled stomach through an external magnetic field. We developed a classification cascade for MGCE images with groups images in semantic and topological categories. Results can be used in a post-procedure review or as a starting point for algorithms classifying pathologies. The first semantic classification step discards over-/under-exposed images as well as images with a large amount of debris. The second topological classification step groups images with respect to their position in the upper gastrointestinal tract (mouth, es…

The Mona Lisa effect: Neural correlates of centered and off-centered gaze

2014

The Mona Lisa effect describes the phenomenon when the eyes of a portrait appear to look at the observer regardless of the observer's position. Recently, the metaphor of a cone of gaze has been proposed to describe the range of gaze directions within which a person feels looked at. The width of the gaze cone is about five degrees of visual angle to either side of a given gaze direction. We used functional magnetic resonance imaging to investigate how the brain regions involved in gaze direction discrimination would differ between centered and decentered presentation positions of a portrait exhibiting eye contact. Subjects observed a given portrait's eyes. By presenting portraits with varyin…

Syntactic Variance and Priming Effects in Translation

2016

The present work investigates the relationship between syntactic variation and priming in translation. It is based on the claim that languages share a common cognitive network of neural activity. When the source and target languages are solicited in a translation context, this shared network can lead to facilitation effects, so-called priming effects. We suggest that priming is a default setting in translation, a special case of language use where source and target languages are constantly co-activated. Such priming effects are not restricted to lexical elements, but do also occur on the syntactic level. We tested these hypotheses with translation data from the TPR database, more specifical…
