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…
The Influence of Sewage Sludge and Fly Ash Fertilization on the Total Number of Bacteria (TNB) and Bradyrhizobium Species in Soybean Agroecosystem
2023
The aim of this study was to determine the impact of different chemical properties in soil, including changes in magnetic susceptibility and the impact of humic substances from sewage sludge and fly ash on the microbial community in the soybean agroecosystem. A field experiment was carried out using the random plot method on Cambisol with a texture of silt loam. The experiment consisted of 24 plots (six treatments and four replications) using different dozes of sewage sludge and fly ash. The following physicochemical and chemical analyses were performed in the soil samples: pH in KCl, conductivity (λ), total content of heavy metal, magnetic measurements and fractional composition of …
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…

Spectroscopy of short-lived radioactive molecules
2020
Molecular spectroscopy offers opportunities for the exploration of the fundamental laws of nature and the search for new particle physics beyond the standard model1–4. Radioactive molecules—in which one or more of the atoms possesses a radioactive nucleus—can contain heavy and deformed nuclei, offering high sensitivity for investigating parity- and time-reversal-violation effects5,6. Radium monofluoride, RaF, is of particular interest because it is predicted to have an electronic structure appropriate for laser cooling6, thus paving the way for its use in high-precision spectroscopic studies. Furthermore, the effects of symmetry-violating nuclear moments are strongly enhanced5,7–9 in molecu…
Implementation of mindfulness-acceptance-commitment protocol for injured athletes : an action research study
2017
Mindfulness-Acceptance-Commitment (MAC) protocol has been implemented and studied for the purpose of performance enhancement with several positive results in the past 10 years. More recently, an increasing, but limited, number of MAC studies have also been done in the field of sport injury prevention and rehabilitation. Since MAC is a protocol with flexible implementation, sport psychology consultants, especially novice, can be confused by a wide range of its strategies. It is important to study implementation because it doesn’t provide only information about the effect but also detailed contents and mechanisms of an intervention, which will reduce variability and fidelity of it. The purpos…
La valeur partenariale : vers une mesure opérationnelle.
2007
L’objectif de cet article est de proposer une mesure operationnelle de la valeur partenariale. Cette mesure est illustree par une application a un certain nombre de firmes europeennes du secteur automobile. Cette application met en evidence l’interet de la demarche pour construire un diagnostic financier permettant de mieux mettre en relation la conception contractuelle de la firme et l’approche strategique.
