Combined use of sonographic and elastosonographic parameters can improve the diagnostic accuracy in thyroid nodules at risk of malignancy at cytologi…
2019
BACKGROUND Thyroid nodules diagnosed as Thy3B at fine-needle aspiration biopsy have a relevant risk of malignancy (15-30%) and are usually addressed to surgery. However surgery will result unnecessary in most cases. The present study aims at evaluating the possible increase of diagnostic accuracy for predicting malignancy using novel sonographic and elastographic parameters. METHODS In fifty patients undergoing thyroidectomy because of a Thy3B thyroid nodule, sonographic and elastosonographic evaluation was carried out by single operator before surgery. Five sonographic parameters (echogenicity, irregular margins, microcalcifications, intra-nodule blood flow and its irregularity) and two el…
Sensor Fusion Combining 3-D and 2-D for Depth Data Enhancement
2012
Time-of-Flight (ToF) cameras are known to be cost-efficient 3-D sensing systems capable of providing full scene depth information at a high frame rate. Among many other advantages, ToF cameras are able to provide distance information regardless of the illumination conditions and with no texture dependency, which makes them very suitable for computer vision and robotic applications where reliable distance measurements are required. However, the resolution of the given depth maps is far below the resolution given by standard 2-D video cameras which, indeed, restricts the use of ToF cameras in real applications such as those for safety and surveillance. In this thesis, we therefore investigate…
Multimodal Perspective into Teachers’ Definitional Practices: Comparing Subject-Specific Language in Physics and History Lessons
2021
This chapter compares two teachers’ definitional practices in two Content-and-Language-Integrated-Learning (CLIL) lessons, i.e. physics and history, which are taught in English in Finland. It adopts Dalton-Puffer’s (Eur J Appl Linguistics 1(2):216–253, 2013; Cognitive discourse functions: specifying an integrative interdisciplinary construct. In: Nikula T, Dafouz E, Moore P, Smit U (eds) Conceptualising integration in CLIL and multilingual education. Bristol: Multilingual Matters, pp. 29–54, 2016) theoretical construct of cognitive discourse functions (CDF) and showcases how it can be operationalized with empirical grounding. Multimodal conversation analysis (CA) is used to trace and observ…
On the conversation between female videobloggers and commentators
2021
El desarrollo de YouTube como una plataforma social surge a partir de dos ideas. En primer lugar, los amateurs pueden producir contenido de cualquier índole. Y, en segundo lugar, su audiencia puede expresar su opinión sin restricciones. Este intercambio de información impulsa la formación de comunidades en torno a un interés común: contenido y/o videobloguero. La dimensión social en YouTube tiene lugar de manera bidireccional. La interacción regular entre las dos partes ha significado un cambio crucial en la percepción de la producción y consumo audiovisual, así como también en los productores de vídeo, amateurs y audiencia. Las investigaciones iniciales se han dirigido a examinar los comen…
Signals of intensification and attenuation in orchestra and choir conduction
2017
Based on a model of communication according to which not only words but also body signals constitute lexicons (Poggi, 2007), the study presented aimes at building a lexicon of conductors’ multimodal behaviours requesting intensification and attenuation of sound intensity. In a corpus of concerts and rehearsals, the conductors’ body signals requesting to play or sing forte, piano, crescendo, diminuendo were analysed through an annotation scheme describing the body signals, their meanings, and their semiotic devices: generic codified (the same as in everyday language); specific codified (shared with laypeople but with specific meanings in conduction); direct iconic, (resemblance between visua…
Classification par méthodes d’apprentissage supervisé et faiblement superviséd’images multimodales pour l’aide au diagnostic du lentigo malin en derm…
2021
Carried out in collaboration with the Saint-Étienne University Hospital, this work provides additional information to help the skin diagnosis by providing new decision methods on Lentigo Maligna and Lentigo Maligna Melanoma pathologies. To this end, the modalities regularly used in clinical conditions are made available to this work and are orchestrated within a multimodal process. Among image modalities, may be mentioned the clinical photography, the dermatoscopy, and the confocal reflectance microscopy. Initially, the first steps of this manuscript focus on reflectance confocal microscopy as the work in computer diagnostic assistance is relatively underdeveloped, in particular on the dete…
Critical Literacy in the subject Norwegian: How students (13–14 years) read and evaluate multimodal commercial texts
2022
Denne artikkelen presenterer funn frå ei spørjeundersøking om kritisk lesing og vurdering som omfattar eit utval på 228 norske elevar på åttande trinn (13–14 år). Studien undersøkjer både kva oppfatningar om kritisk lesing elevane formidlar og korleis elevar vurderer og grunngir lesinga si av multimodale kommersielle tekstar. Eit hovudfunn i studien er at forståinga av kritisk lesing som kjeldekritikk er mest utbreidd blant elevane. Ein stor del av elevane har såleis ei rimeleg, men avgrensa oppfatning av kva det vil seie å nærme seg ein tekst på ein kritisk måte. Elevane forbind i mindre grad kritisk lesing med det å nærme seg teksten på ein analytisk måte. Eit anna hovudfunn er at ein del…
Schweigen in Videokonferenzen: Vom Umgang mit Störungen in Online-Besprechungen
2020
This paper deals with silence in video-based discourse, which includes pauses and delays. The data of the study is provided by international video conferences in which six in-service teachers and six pre-service teachers from three countries (Italy, the Netherlands, Hungary) together with a moderator and an assistent discuss sequences of their lessons. These discussions are part of a teacher training progrmme as conceived and implemented in the Erasmus+ project LEELU (www.leelu.eu). The focus of the present study is to analyse through a multimodal approach how the above-mentioned moments of silence co-constitute the video-based interaction, and how the discourse is built up with the other m…
La promoción de la imagen política en Instagram: un estudio del perfil personal de Santiago Abascal (Vox) en 2018
2020
Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…
Exploiting multimodality for intelligent mobile access to pervasive services in cultural heritage sites
2010
In this chapter the role of multimodality in intelligent, mobile guides for cultural heritage environments is discussed. Multimodal access to information contents enables the creation of systems with a higher degree of accessibility and usability. A multimodal interaction may involve several human interaction modes, such as sight, touch and voice to navigate contents, or gestures to activate controls. We first start our discussion by presenting a timeline of cultural heritage system evolution, spanning from 2001 to 2008, which highlights design issues such as intelligence and context-awareness in providing information. Then, multimodal access to contents is discussed, along with problems an…
