Visual exploration and discrimination of emotional facial expressions in 3-, 7- and 12-month-old infants

2015

The first year of life is critical in the development of the abilities to process facial expressions. Numerous studies have investigated discrimination and categorization of distinct facial expressions of emotion. However, infants' visual exploratory strategies of these facial expressions and their developmental paths remain unclear. The perfection of eye movement tracking systems makes now the detailed analysis of facial exploration of faces feasible, and hence facilitates the identification of the features in facial expressions which infants focus on. In this study, oculometric parameters of 3- (n=36), 7- (n=66) and 12-month-old infants (n=59) were collected while facial expressions were …

Automated classification of neurodegenerative parkinsonian syndromes using multimodal magnetic resonance imaging in a clinical setting

2020

ABSTRACTBackgroundSeveral studies have shown that machine learning algorithms using MRI data can accurately discriminate parkinsonian syndromes. Validation under clinical conditions is missing.ObjectivesTo evaluate the accuracy for the categorization of parkinsonian syndromes of a machine learning algorithm trained with a research cohort and tested on an independent clinical replication cohort.Methods361 subjects, including 94 healthy controls, 139 patients with PD, 60 with PSP with Richardson’s syndrome, 41 with MSA of the parkinsonian variant (MSA-P) and 27 with MSA of the cerebellar variant (MSA-P), were recruited. They were divided into a training cohort (n=179) scanned in a research en…

Mentālo slimību kategorizācija un pieņemšana vācu medicīnas studentu vidū

2020

Izmantojot medicīnas antropoloģijas pieeju un Guda un Klainmana darbus, es pētu, kā medicīnas studenti no Vācijas kategorizē mentālas grūtības. "Mentālas grūtības" attiecas uz dažāda līmeņa pieredzēm, kuras pētījuma dalībnieki uzskatīja par nepatīkamām. Balstoties padziļinātās intervijās un līdzdalīgajā novērojumā, es parādu, kā grūtības tiek kategorizētas kā nopietnas/nekaitīgas un normālas/nenormālas. Pirmā atšķirība balstījās pašu student noteiktos konkrētos kritērijos, kamēr grūtību nosaukšana par "normālām" saistījās ar pašu p’et’ijuma dalībnieku studiju pieredzi. Savas un tuvu draugu grūtības tika normalizētas. Lai izprastu šo normalizāciju, es pētīju medicīnas studenta ideālu. Saskar…

Understanding beginners' mistakes with Haskell

2015

AbstractThis article presents an overview of student difficulties in an introductory functional programming (FP) course taught in Haskell. The motivation for this study stems from our belief that many student difficulties can be alleviated by understanding the underlying causes of errors and by modifying the educational approach and, possibly, the teaching language accordingly. We analyze students' exercise submissions and categorize student errors according to compiler error messages and then manually according to the observed underlying cause. Our study complements earlier studies on the topic by applying computer and manual analysis while focusing on providing descriptive statistics of d…

Automatic dynamic texture segmentation using local descriptors and optical flow

2012

A dynamic texture (DT) is an extension of the texture to the temporal domain. How to segment a DT is a challenging problem. In this paper, we address the problem of segmenting a DT into disjoint regions. A DT might be different from its spatial mode (i.e., appearance) and/or temporal mode (i.e., motion field). To this end, we develop a framework based on the appearance and motion modes. For the appearance mode, we use a new local spatial texture descriptor to describe the spatial mode of the DT; for the motion mode, we use the optical flow and the local temporal texture descriptor to represent the temporal variations of the DT. In addition, for the optical flow, we use the histogram of orie…

The Recurrent Characteristics of Historic Buildings as a Support to Improve their Energy Performances: The Case Study of Palermo

2017

Abstract The analysis of the recurrent characteristics of the local historic architecture is useful to develop large-scale energy analyses, regulations and financial strategies, but also to support technical guidelines for an energy improvement balanced with conservation. For this purpose, a multi-scale methodology ranging from envelope components to the urban dimension is necessary. In the research here exposed, this approach is investigated by focusing on the historic architecture of Palermo. For this heritage, the collection of thermal and hygrometric data for envelope components is combined with the examination of representative constructions, based on building stock categorization. Int…

Nazwy krzewów w śląskiej toponimii

2017

The paper deals with geographical names in Silesia deriving from shrub species names. An analysis of the names derived from appellatives allows for a reconstruction of the categorization methods of the world, anthropological conceptualization and a popular image of reality. Name creators choose those names from the existing collection of the names derived from the appellatives which are for certain reasons important and valuable for them. For example, the following names of shrubs become a productive toponymic base: hazel, blueberry, rose; they belong to the basic categorization level and are important for the rural community due to their usable and practical significance (in construction a…

Challenging Transmission Modes of Teaching in Science Classrooms : Enhancing Learner-Centredness through Dialogicity

2017

There is an ongoing reform towards more inquiry-based teaching in school curriculum policy in South Africa. Reform towards more inquiry-based approaches is already integrated in pre-service teacher education programmes. As inquiry-based approaches have been gaining momentum worldwide, there is an increasing concern that dialogic interaction in classroom communication is being neglected. This is especially within teacher-orchestrated classroom interactions that should foster greater learner centredness and thus authentic scientific inquiry. In learner-centred teaching approaches, student contributions should be explicitly taken into account as part of classroom interactions in science. Learn…
