A deep learning segmentation approach to calories and weight estimation of food images
2019
Master's thesis Information- and communication technology IKT590 - University of Agder 2019 Today’s generation is very aware of what they are eating and the amountof calories in their food. Eating too many calories can lead to increasedweight, which has become a big health issue. A study from 2016 states thatmore than 1,9 billion adults are overweight where almost one third of theseare obese. Statistics from Norway show that 1 of 4 men and 1 of 5 womenare obese.Artificial Intelligence in general and deep learning in particular can be usedto help understand the content of eaten food. In this master thesis, wepropose a network to estimate the weight of food from a single image. Thisis done in…
EXTRA VIRGIN OLIVE OIL IMPROVES LEARNING AND MEMORY IN SAMP8 MICE
2011
Abstract. Polyphenols are potent antioxidants found in extra virgin olive oil (EVOO); antioxidants have been shown to reverse age- and disease-related learning and memory deficits. We examined the effects of EVOO on learning and memory in SAMP8 mice, an age-related learning/memory impairment model associated with increased amyloid- protein and brain oxidative damage. We administered EVOO, coconut oil, or butter to 11 month old SAMP8 mice for 6 weeks. Mice were tested in T-maze foot shock avoidance and one-trial novel object recognition with a 24 h delay. Mice which received EVOO had improved acquisition in the T-maze and spent more time with the novel object in one-trial novel object recogni…
A Design-Oriented Analysis of Multimodality in English as a Foreign Language
2018
This empirical article investigates multimodality in English as a foreign language, both as seen in the use of multimodal texts as artefacts and pedagogical texts for learning, and through an analysis of the multimodal learning designs. We present observations from a year 10 classroom in Norway that worked with the novel The Absolutely True Diary of a Part-Time Indian (Alexie, 2007). We explore a four-week teaching sequence, asking how different modes were involved when the educator designed literacy events around the novel, and how multimodality is present in the students’ meaning making. Our aim is to make explicit and discuss some of the silent literacy practices in English teaching at l…
Going into the real world : language learners' views on how foreign language teaching prepares them to use language in authentic situations
2014
Englannin kieli nähdään oikeutetusti maailmankielenä, sillä se on vakiinnuttanut asemansa kansainvälisen kommunikaation välineenä. Kielenkäyttö ja kommunikatiivisuus ovat olleet teoriassa vieraiden kielten opetuksen tärkeimpiä tavoitteita jo pitkään. Tämän tutkimuksen tarkoitus oli tarkastella kielenoppijoiden näkemyksiä siitä, miten englannin kielen opetus suomalaisessa peruskoulussa valmistaa oppijoita käyttämään kieltä autenttisissa kielenkäyttötilanteissa peruskoulun jälkeen. Tarkoituksena oli myös selvittää, mitkä opetuksen osa-alueet lisäävät oppijoiden kykyä käyttää kieltä. Lisäksi tutkimus pyrki selvittämään, millaisia kielenkäyttötilanteita oppijat ovat kokeneet. Tutkimuksen tavoit…
Science and law in the time of cholera: the mystery of the biscuits in Torroja (1865)
2018
By focussing on a case of collective poisoning in 1865, four features of forensic cultures are analysed: technologies for detection, authorized voices, regulations in action and the predominant social anxieties. Local newspapers and archival documents kept in the medical academies of Barcelona and Madrid are analysed. The analysis shows the tensions between various types of proof employed in legal medicine and the ambiguities between epidemic diseases and poisoning accidents. In the first section, I review the fears caused by the cholera epidemic in 1865, which was the first explanation of the accident. The changes of popular perception are also discussed by analysing contemporary newspaper…
Digital solutions transform the forest-based bioeconomy into a digital platform industry : a suggestion for a disruptive business model in the digita…
2018
With the notion that the transformation of the forest-based bioeconomy in recent years provides insightful suggestions not only on the bioeconomy, but on business innovation, this paper conducts an empirical analysis of the transformation and attempts to extract suggestions for a digital-solution-driven, disruptive business model in the digital economy. Notwithstanding the potential broad cross-sectoral benefits, the natural environment, locality constraints, and incessant challenge of distance have impeded the balanced development of the bioeconomy. However, driven by digital solutions, the bioeconomy has taken big steps forward in recent years. Digitalization has enabled real-time, end-to…
Competenza digitale dei docenti e disabilità. Formazione su Episodi di Apprendimento Situato (EAS) per l'innovazione didattica.
2018
Il percorso di ricerca intrapreso mi ha permesso di strutturare una serie di riflessioni, già avviate all’interno di percorsi di studio universitari precedenti, relativamente all’evidente alta inclusività propria delle Tecnologie dell’informazione e della Comunicazione (TIC) a supporto di alunni con Bisogni Educativi Speciali (BES). A partire dall’assunto che l’innovazione digitale della didattica passi necessariamente dalla consapevole orchestrazione dei diversi strumenti tecnologici e che l’innovazione didattica preceda quella digitale, si è reputato doveroso indagare relativamente alle modalità di sviluppo e di miglioramento delle competenze digitali dei docenti, soprattutto, per quanti …
Pathways Through Peer Assessment: Implementing Peer Assessment in a Lower Secondary Physics Classroom
2020
AbstractPeer assessment has been shown to advance learning, for example, by improving one’s work, but the variance of learning benefits within or between studies has not been explained. The purpose of this case study was to examine what kinds of pathways students have through peer assessment and to study which factors affect them when peer assessment is implemented in the early stage of physics studies in the context of conducting and reporting inquiry. Data sources used include field notes, audio recordings of lessons, student lab reports, written peer feedback, and student interviews. We examined peer assessment from the perspective of individual students and found 3 profiles of peer asse…
Il valore della formazione integrata tra scuola e lavoro
2021
La metodologia Alternanza Scuola Lavoro, caratteristica dei percorsi di apprendimento basati sul lavoro (Work–Based Learning), è inserita all’interno dei curricoli scolastici e di quelli di istruzione e formazione professionale, presenti sia nel modello educativo italiano sia nella maggior parte dei sistemi educativi europei. I presupposti teorici che l’hanno definita e promossa sono rintracciabili nei primi programmi di Work placements, sandwich courses e negotiated learning, nati dagli studi di John Dewey che concepiva l’istruzione scolastica come un laboratorio continuo di educazione alla vita. Tali programmi sono stati proposti intorno agli anni Settanta–Ottanta nelle università e negli…
Il Transformative Learning nei futuri insegnanti di sostegno: un’indagine in laboratorio
2022
Il presente lavoro illustra gli esiti di un’indagine condotta con 2193 corsisti frequentanti i laboratori del VI ciclo del corso di specializzazione per le attività di sostegno didattico dell’Università degli Studi di Palermo svoltosi nell’A.A. 2021/2022. La finalità dell’indagine è stata quella di rilevare il grado di consapevolezza dei taciti assunti e delle aspettative, nonché di quelle degli altri e valutarne la rilevanza a fini interpretativi, dei futuri docenti di sostegno, nel processo laboratoriale che li ha coinvolti per 180 ore. La cornice teorica all’interno della quale si delinea l’indagine è quella del Transformative Learning (Mezirow, 2013), che riteniamo fondamentale per la c…
