On the relations between audio features and room acoustic parameters of auralizations
2013
The usual parameters in room acoustics are used to quantify the acoustic characteristics of rooms and their relation to the subjective perception of transmitted signals. Audio features (calculated with MIRToolbox) have been designed to study the relationships between the characteristics of musical audio files and their subjective perception. Both musical characteristics and acoustic parameters are oriented towards acoustic perception. By using auralizations with calibrated models of auditoriums and tools from the MIRtoolbox it is possible to jointly work with the calculation of audio features and room parameters. In this work, the statistical correlations between C80, STI, D50, EDT, RT and …
Visual scale factor for speed perception
2011
Speed perception is an important task depending mainly on optic flow that the driver must perform continuously to control his/her vehicle. Unfortunately, it appears that in some driving simulators speed perception is under estimated, leading into speed production higher than in real conditions. Perceptual validity is then not good enough to study driver’s behavior. To solve this problem, a technique has recently seen the light, which consists of modifying the geometric field of view (GFOV) while keeping the real field of view (FOV) constant. We define our visual scale factor as the ratio between the GFOV and the FOV. The present study has been carried out on the SAAM dynamic driving simulat…
Multicolour LEDs in educational demonstrations of physics and optometry
2014
LED light sources are used to design experimental setup for university courses teaching human color vision. The setup allows to demonstrate various vision characteristics and to apply for student practical exercises to study eye spectral sensitivity in different spectral range using heterochromatic flicker photometry. Technique can be used in laboratory works for students to acquire knowledge in visual perception, basics of electronics and measuring, or it can be applied as fully computer control experiment. Besides studies of the eye spectral sensitivity students can practice in trichromatic color matching and other visual perception tasks
Safety climate responses and the perceived risk of accidents in the construction industry
2008
The usefulness of safety climate as a diagnostic tool ought to reside in its ability to identify detailed and precise difficulties that can be considered critical to improving safety. This feature depends on the theoretical analysis of the agents and issues that should be included in safety climate statements. Safety climate can be analysed from the point of view of the agent that performs the safety response in question, by identifying four main safety agents (organization, supervisors, co-workers and worker) and five safety climate variables: the Organizational Safety Response (OSR), the Supervisors' Safety Response (SSR), the Co-Workers' Safety Response (CSR), the Worker Safety Response …
Self-efficacy and performance of the roundhouse kick in taekwondo
2014
[ES] El desarrollo de escalas de autoeficacia permite el análisis de las percepciones de los deportistas y el examen de la relación entre dichas percepciones y el rendimiento. El objetivo de este estudio fue (1) desarrollar una escala específica de autoeficacia para una tarea de taekwondo, la patada circular, y (2) analizar el rendimiento deportivo y su relación con los resultados de dos escalas de autoeficacia (específica y general) en función del género de los deportistas. En el estudio participaron 43 taekwondistas (33 hombres y 10 mujeres). Se administraron las escalas de autoeficacia Física (PSE) y Específica (RKSES). Los datos de rendimiento (fuerza de impacto y tiempo total de respue…
Visual Behaviour Based Bio-Inspired Polarization Techniques in Computer Vision and Robotics
2012
For long time, it was thought that the sensing of polarization by animals is invariably related to their behavior, such as navigation and orientation. Recently, it was found that polarization can be part of a high-level visual perception, permitting a wide area of vision applications. Polarization vision can be used for most tasks of color vision including object recognition, contrast enhancement, camouflage breaking, and signal detection and discrimination. The polarization based visual behavior found in the animal kingdom is briefly covered. Then, the authors go in depth with the bio-inspired applications based on polarization in computer vision and robotics. The aim is to have a comprehe…

2019
Darba nosaukums: Vecākā pirmsskolas vecuma bērnu krāsu uztveres sekmēšana tēlotājdarbībā pirmskolā. Pētījuma mērķis: teorijā un praksē pārbaudīt vai tēlotājdarbībā iespējams sekmēt vecākā pirmskolas vecuma bērnu krāsu uztveres attīstību. Teorētiskajā daļā apskatīts kāda ir tēlotājdarbības nozīme bērna personības vispusīgā attīstībā, ņemot vērā krāsas lielo ietekmi uz bērna un vēlāk arī uz pieauguša cilvēka emocionālo attīstību. Analizēta literatūra saistībā ar mākslas un krāsu attīstošo ietekmi. Teorētiskā daļa balstās uz D. Lambergas, L. Slavas, I. Celmiņas, M. Dobles, E.Ozola, L. Ozola, P. Antona, Ē. Antona, lekciju materiāliem no Doc.,Dr.,paed. D.Kalējas – Gasparovičas, VISC Pirmskolas i…
Perceived collective continuity and social well-being: exploring the connections
2008
Research has shown that people tend to perceive the groups to which they belong (e.g., national groups) as temporally persistent. In this paper we argue that enhanced perceptions of collective continuity lead to lower levels of anomy and misfit, and to higher levels of social well-being (SWB). Furthermore, we argue that the effects of perceived collective continuity (PCC) on SWB are mediated by collective self-esteem (CSE). Finally, we contend that PCC has positive effects on perceived group entitativity (PGE), which in turn has a positive influence on CSE. This model is tested by means of a cross-sectional study using a sample of Spanish nationals (N = 145) drawn from the general public. R…
Perceived family continuity: Implications for family identification and psychological well-being
2011
AbstractResearch has shown that people tend to perceive the national and regional groups to which they belong as temporally persistent. In this paper we conducted two studies to investigate that the family may also be perceived as having different degrees of continuity through time, and that those perceptions have implications on family identity and psychological well-being. In the first study (N = 149; with a mean age of 23, SD = 5.7), we found that perceived family continuity was positively correlated with several family related variables (e.g., family functioning, perceived family entitativity) and with psychological well-being. Our second study (N = 152; with a mean age of 40.80, SD = 1…
Indexes as Business Environment Characterizing Instruments
2017
Every year several world organizations evaluate countries according different criteria and determine their indexes, such as KOF Index of Globalization, Corruption Perception Index, Global Competitiveness Index, Global Innovation Index, and others. These indexes later are used for analysis of the aspects of entrepreneurship activities in specific countries. One particular application of indexes is related to analysis and evaluation of the business environment of the country. The entrepreneurship is affected by many factors; to research all of them is very time and effort consuming process. The proposed approach (i.e., use of indexes) is targeted and can yield results of the practical signifi…
