Producción del sistema vocálico del español por hablantes de chino
2018
En este trabajo se comparan los sistemas vocálicos del español y del chino pronunciados por hablantes nativos con el objetivo de presentar a continuación las peculiaridades del sistema vocálico español de un grupo de estudiantes de China con un nivel intermedio de español. El estudio de las similitudes y las diferencias entre los sistemas nativos nos ha permitido prever en qué áreas pueden diferir las vocales pronunciadas por aprendices chinos de las vocales españolas. Los resultados indican que el sistema vocálico español de los estudiantes chinos es estructuralmente similar al sistema nativo, pero con algunas diferencias fonéticas: en primer lugar, tiene una extensión mayor por lo que res…
Early markers of language delay in children with and without family risk for dyslexia
2015
Accepted manuscript version. Published version at http://doi.org/10.1177/0142723715596122. This study examined the extent to which receptive and productive vocabulary between ages 12 and 18 months predicted language skills at age 24 months in children born with family risk for dyslexia (FR) and a control group born without that risk. The aim was to identify possible markers of early language delay. The authors monitored vocabulary growth in 32 FR children and 21 control children longitudinally by using the Norwegian adaption of the MacArthur–Bates Communicative Development Inventories. The results show different patterns in the two groups: the study found a stronger interdependence of early…
A lexicographic Study: Medical Vocabulary in use
2011
INTRODUCTION Information, research and new ideas in medicine are spread mainly by the written word. Therefore, reading and writing are fundamental skills in collecting information and building a wide knowledge base not only in the student population but even as practising physicians and specialists. Knowing lexical items is an important building block in developing both of these language skills. There are several different measures of lexicographic competence, such as the General Service List or GSL (West, 1953), Academic Word List or AWL (Laufer &Nation,1999; Coxhead, 2000) and Medical Academic Word List or MAWL (Wang, Liang & Ge, 2008). The purpose of this study is to measure lexical comp…
The Structure and Usage of Female and Male Mouse Ultrasonic Vocalizations Reveal only Minor Differences
2012
Ultrasonic vocalizations (USV) of mice are increasingly recognized as informative dependent variables in studies using mouse models of human diseases. While pup vocalizations primarily serve to re-establish contact with the mother, adult male ‘‘songs’’ were considered to be courtship signals. Alternatively, mouse USVs may generally function as territorial signals. To distinguish between these two hypotheses, we compared the structure and usage of adult male and female USVs in staged resident-intruder encounters. If calls function primarily as courtship signals, males should respond stronger than females, specifically when presented with a female intruder. Refuting this hypothesis, we found …
Postoperative laryngeal symptoms in a general surgery setting. Clinical study.
2013
INTRODUCTION: Vocal cord injuries (VI), postoperative hoarseness (PH), dysphonia (DN), dysphagia (DG) and sore throat (ST) are common complications after general anesthesia; there is actually a lack of consensus to support the proper timing for post-operative laryngoscopy that is reliable to support the diagnosis of laryngeal or vocal fold lesions after surgery and there are no valid studies about the entity of laryngeal trauma in oro-tracheal intubation. Aim of our study is to evaluate the statistical relation between anatomic, anesthesiological and surgical variables in the case of PH, DG or impaired voice register. MATERIALS AND METHODS: 50 patients (30 thyroidectomies, 8 videolaparoscop…
Prenatal exposure to the CB1 receptor agonist WIN 55,212-2 causes learning disruption associated with impaired cortical NMDA receptor function and em…
2005
The aim of this study was to investigate whether prenatal exposure to the cannabinoid CB1 receptor agonist WIN 55,212-2 (WIN) at a daily dose devoid of overt signs of toxicity and/or gross malformations (0.5 mg/kg, gestation days 5-20), influences cortical glutamatergic neurotransmission, learning and emotional reactivity in rat offspring. Basal and K+-evoked extracellular glutamate levels were significantly lower in cortical cell cultures obtained from pups exposed to WIN during gestation with respect to those measured in cultures obtained from neonates born from vehicle-treated dams. The addition of NMDA to cortical cell cultures from neonates born from vehicle-treated dams concentration-…
Computational fluid dynamics in the assessment of patients' postoperative status after glottis-widening surgery
2017
Background. Computational fluid dynamics (CFD), a rapidly developing instrument with a number of practical applications, allows calculation and visualization of the changing parameters of airflow in the upper respiratory tract. Objectives. The aim of this study was to demonstrate the advantages of CFD as an instrument for noninvasive tests of the larynx in patients who had undergone surgical treatment due to bilateral vocal fold paralysis. Material and Methods. Surface measurements of the glottic space were made during maximum adduction of the vocal folds. Additionally, the following spirometric parameters were determined: forced vital capacity (FVC), forced expiratory volume in the first s…
Reading outcomes of children with delayed early vocabulary: A follow-up from age 2-16.
2018
Abstract Background Delays in expressive vocabulary have been associated with lower outcomes in reading. Aim The aim is to conduct a long-term follow-up study to investigate if early expressive vocabulary delay (late talking) predicts reading development in participants age 16 and under. We examine further if the prediction is different in the presence of family risk for dyslexia (FR) and early receptive vocabulary delay. Methods Expressive and receptive vocabulary skills were assessed at the age of 2–2.5 years, and reading skills in Grades 2, 3, 8 and 9 (age 8–16). The longitudinal sample consisted of 200 Finnish-speaking children, of which 108 had FR for dyslexia and 92 came from families…
Effects of weathering on the performance of self-cleaning photocatalytic paints
2019
Abstract The use of photocatalytic products for the surface coating of buildings is spreading more and more, because of the reduction of atmospheric pollutants and the colour maintenance of the paints over time with reduction of the maintenance costs and the improvement of the aesthetic appearance. The study reports the evaluation of the effects of the atmospheric conditions on three commercial photocatalytic paints containing TiO2. In particular tests were carried out by using samples subjected to accelerated aging inside a climate chamber and naturally aged by exposure for two years to the external environment of the city of Palermo (representative of a coastal environment of the Mediterr…
Instructors' Competence for Enhancing Quality of In-House Training in Maritime Education
2015
<p class="IATED-Affiliation">Improving instructors’ competence will enhance quality of maritime in-house training (IHT). The research question of this study was: what are the main features of a competent IHT instructor? A mixed-method study using interviews and a questionnaire was conducted among three groups of respondents: 1) safety managers, vetting and technical managers; 2) IHT instructors, and 3) seafarers (including masters, chief engineers, officers and ratings). Professionals of the field were involved in interpretation of results and in elaboration of the recommendations for enhancing quality of IHT.</p><p class="normal"> </p>
