Pronunciation Learning Environment: EFL Students' Cognitions of In-class and Out-of-class Factors Affecting Pronunciation Acquisition
2018
The way a foreign language (L2) learner perceives his or her educational environment may affect their processes of L2 acquisition. The aim of the study presented in this paper is to explore English as a foreign language (EFL) students’ perceptions of their teachers’ pronunciation, in-class and outside-class factors regarding pronunciation acquisition, such as pronunciation activities, recordings, focus on form, peer pronunciation, listening to music, to mention a few. A group of 89 participants responded to a survey, via which the data necessary to respond to the following three research questions was collected. How do EFL learners perceive their teachers’ pronunciation? What is the relatio…
Cross modal interactions: way to counterbalance salt reduction in solid foods?
2008
International audience; Four model cheeses varying in texture (2 Dry Matter (DM) levels; 2 Fat/DM levels and 1 salt level) were designed and flavored with 3 commercial tasteless aromas (“Comté Cheese”, Sardine and Carrot) differently associated with salty and cheesy food products. Thirty untrained subjects were instructed to evaluate taste intensity (sourness, bitterness, saltiness and sweetness), aroma intensity, texture attributes (firmness, moistness and graininess), aroma congruency with the product and their hedonic appreciation of the 12 flavored and 4 unflavored model cheese samples. A comparison of the saltiness perception of the flavored and unflavored model cheeses revealed cross-…
Physicochemical and perceptual interactions between composition/texture, taste and aroma: A way to enhance saltiness in foods
2009
Diplôme : Ph. D.; Excessive salt in the human diet is a major risk factor for hypertension and cardiovascular diseases. So, the World Health Organisation (WHO) advocates sodium reduction of foods as a cost-effective strategy to improve public health. Because of important functionalities of salt (NaCl) – salty taste and flavour enhancement, solutions are being sought to lower the salt content of processed foods without altering their taste. In this PhD work, the approach proposed was to use sensory interactions between the senses, especially composition/texture – saltiness interactions (i) and aroma-saltiness interactions (ii). The first part of this work aimed to investigate food compositio…
Suppressive Efficacy by a Commercially Available Blue Lens on PPR in 610 Photosensitive Epilepsy Patients
2006
Purpose Photosensitivity can represent a serious problem in epilepsy patients, also because pharmacologic treatment is often ineffective. Nonpharmacologic treatment using blue sunglasses is effective and safe in controlling photosensitivity, but large series of patients have never been studied. Methods This multicenter study was conducted in 12 epilepsy centers in northern, central, southern, and insular Italy. A commercially available lens, named Z1, obtained in a previous trial, was used to test consecutively enrolled pediatric and adult epilepsy patients with photosensitivity. Only type 4 photosensitivity (photoparoxysmal response, PPR) was considered in the study. A standardized method …
La perception des accords aromatiques : un exemple d'interactions perceptives dans les mélanges odorants
2007
Diplôme : Dr. d'Université; Dans le monde de la parfumerie et de l'aromatique, il existe un terme particulier définissant la formation d'une nouvelle qualité odorante à travers le mélange et la fusion de plusieurs odeurs : l'accord. Ce terme, largement employée parmi ces experts, n'avait jamais donné lieu à des études scientifiques approfondies.L' objectif de cette thèse a été de démontrer la réalité de l'accord en olfaction et de montrer qu'il repose sur des interactions perceptives influençant la qualité de l'odeur. Nous avons en particulier étudié les déterminants physico-chimiques, perceptifs et cognitifs des accords aromatiques. Dans un premier temps, nous avons démontré que la percept…
Electrophysiological evidence for change detection in speech sound patterns by anesthetized rats
2014
Human infants are able to detect changes in grammatical rules in a speech sound stream. Here, we tested whether rats have a comparable ability by using an electrophysiological measure that has been shown to reflect higher order auditory cognition even before it becomes manifested in behavioral level. Urethane-anesthetized rats were presented with a stream of sequences consisting of three pseudowords carried out at a fast pace. Frequently presented “standard” sequences had 16 variants which all had the same structure. They were occasionally replaced by acoustically novel “deviant” sequences of two different types: structurally consistent and inconsistent sequences. Two stimulus conditions we…
Situational Perception in Mathematics (SPiM)—Results of a Cross-Country Study in Austria and Norway
2020
Situation-specific skills, as situational perception, are a central part of educators’ competence. This is especially true for kindergarten teachers (KTs) as most of their teaching is based on natural learning situations. The aim of this study is to contribute to the discussion on KTs’ situational perception by identifying aspects of early childhood education students’ situational perception in mathematics. Therefore, we conducted a qualitative study with N = 5 students from Austria and N = 5 students from Norway. Data was collected through a video-based questionnaire: The students watched seven video vignettes and wrote down their observations and reflections immediately upon watching. Dat…
¿Qué ciencias se enseñan y cómo se hace en las aulas de educación infantil? : La visión de los maestros en formación inicial
2016
Los conocimientos científicos están presentes en los currículos de todos los niveles educativos. Sin embargo, son pocas las investigaciones orientadas a saber qué contenidos se enseñan, cómo lo hacen, qué aprende el alumnado… en la etapa de educación infantil. En este trabajo estudiamos la percepción que tienen los futuros maestros sobre la enseñanza de las ciencias que se realiza en las aulas de segundo ciclo de esta etapa. A partir de sus vivencias en las prácticas de enseñanza, unos estudiantes del Grado de Educación Infantil han respondido a un cuestionario elaborado para conocer mejor la realidad educativa que estamos estudiando. Los resultados ponen de manifiesto el escaso tratamiento…
Perspectives on Leadership in Early Childhood Education and Care Centers Through Community of Practice
2021
This article investigates early childhood education and care (ECEC) leadership through the concept of community of practice (COP). The focus is on ECEC leaders’ perceptions regarding their leadership during the educational changes taking place in the context of Finnish ECEC. The purpose is to increase understanding of how leaders see themselves in relation to the ECEC multi professional working community and practices of distributed leadership. The data are five focus group interviews of ECEC leaders analyzed with directed content analysis within the theoretical frame of domain, practice, and community forming the core of COP in Lave and Wenger. The results show how all three COP component…
Perceptions of early childhood education professionals on teacher leadership in Finland
2016
This study investigated perceptions of early childhood education (ECE) professionals employed at three ECE centres on teacher leadership enactment in Finland. These professionals comprised childcare nurses, teachers and ECE centre directors. Theoretically, the study was anchored on an analysis of teacher leadership and distributed leadership literature comprising research based in early childhood and school education contexts. Findings based on focus groups and interviews with participants suggest that teacher leadership was perceived as a responsibility of ECE pedagogy in Finland. Centre directors were considered remote from daily practice and leadership for pedagogy within the centres was…
