De la perception de la voyelle /y/ chez des apprenants polonais du français langue étrangère
2019
The main objective of this study is to test the perception of the vowel /y/ among the Polish learners of FLE, as it does not exist in their natural vowel system. We defend the hypothesis that optimal perception conditions can make the identification and acquisition of new sounds more intelligible.
How Much Does Earphone Quality Matter While Listening to Music on Buses and Trains?
2013
We report results from an investigation into the relationships between acoustic performance, price, and perceived quality of earphones. In Singapore today, the most common situation where people listen to music is while commuting, however such environments have generally high ambient noise levels. A survey (N=94) of listener habits on buses and trains was conducted. Results showed that people use a wide range of earphones, both in terms of price and measurable acoustic performance. Five typical earphone models were identified and employed in a perceptual experiment (N=15). Volunteers rated various aspects of earphone quality while listening to music under two conditions: studio silence and …
Effect of Cycloplegia on Blur Perception Thresholds as Measured by Source Method
2017
Abstract One of the advantages of a source method over observer method in blur perception measurements is better control of a stimulus blur level, which is achieved with computerised image processing unlike the observer method that requires optical defocusing of the observer. The aim of this study was to determine if paralysation of accommodation has effect on blur perception thresholds, thereby evaluating its necessity in such experiments. Blur perception thresholds (just noticeable blur, clear image, recognition, and non-resolvable blur thresholds) were evaluated with (using cycloplegia) and without paralysed accommodation to determine effect on blur perception. A computerised low-pass sp…
Assessing risk perception over recidivist traffic offenders from a multi-group approach: how gendered could it be?
2022
ABSTRACT Objective: The core aim of this study was to examine the predictive role of demographic, psychosocial and driving features of Spanish drivers on their risk perception over recidivist traffic offenders, focusing on gender as a key differentiating factor. Method: For this cross-sectional study, it was analyzed the data gathered from a nationwide sample of 1,711 licensed drivers from the 17 regions of Spain (49% females, 51% males) with a mean age of 40.07 years, responding to a telephone-based interview on road safety issues. Demographic, driving-related and psychosocial factors were comparatively analyzed through robust tests and a bias-corrected MGSEM (Multi-Group Structural Equati…
Coping with Uncertainty in an Agile Systems Development Course
2018
Uncertain and ambiguous environments are commonplace in information systems development (ISD) projects, and while different Agile frameworks welcome changes in organizational, technical, and business environments, the incurred uncertainty is known to negatively affect the development process and the quality of the final product. The effects of uncertainty on ISD projects have been studied in the past in real organizational contexts, but the effects of uncertainty on students in Agile systems development have received less attention from scholars. In this study, we measured the effects of experienced uncertainty on students’ performance in an Agile systems development course and how uncertai…

Vaya valla! The phenomenon of "yeísmo" in oral Spanish in Valencia
2016
En los últimos años, el fenómeno del yeísmo ha sido abordado desde diferentes perspectivas; una de ellas es la sociolingüística, a la que nuestro trabajo pretende contribuir. El objetivo de este artículo es presentar cómo evoluciona el proceso fonético de deslateralización del fonema /ʎ/ a favor de /ʝ/ en el castellano de la comunidad de habla bilingüe de Valencia y su área metropolitana. Tradicionalmente se ha señalado que Valencia mantenía la diferenciación entre la lateral y fricativa palatales, pero estudios recientes dan cuenta de la introducción y expansión del yeísmo en determinadas comarcas bilingües de la Comunidad Valenciana. En el análisis sociolingüístico realizado actúan grupos…
Sāpju intensitāte atkarībā no subjektīvā laika
2018
Darba mērķis bija noskaidrot, vai maldinoša laika reprezentācija, ietekmē sāpju intensitātes uztveri. Darba hipotēze bija, vai manipulējot ar subjektīvā laika uztveri jeb rādot maldinošu laika reprezentāciju, samazināsies sāpju intensitāte. Pirmās eksperimentālās grupas rādītāji ir M = 5,15, SD = 1,24, šie rādītāji salīdzinājumā ar otro eksperimentālo grupu ir augstāki M = 4,18, SD = 1,19, darba hipotēze tika apstiprināta. Kopā pētījumā bija 58 dalībnieki, 35 vīrieši, vecums M = 22,40, SD = 2,49 un 23 sievietes, vecums M = 24,52, SD = 4,11. Bija dubultaklais pētījuma dizains ar divām eksperimentālām grupām, pirmā eksperimentālā grupa (n = 28) un otrā eksperimentālā grupa (n = 30). Darba aut…
