Recognition of static and dynamic facial expressions: Influences of sex, type and intensity of emotion

Ecological validity of static and intense facial expressions in emotional recognition has been questioned. Recent studies have recommended the use of facial stimuli more compatible to the natural conditions of social interaction, which involves motion and variations in emotional intensity. In this study, we compared the recognition of static and dynamic facial expressions of happiness, fear, anger and sadness, presented in four emotional intensities (25 %, 50 %, 75 % and 100 %). Twenty volunteers (9 women and 11 men), aged between 19 and 31 years, took part in the study. The experiment consisted of two sessions in which participants had to identify the emotion of static (photographs) and dynamic (videos) displays of facial expressions on the computer screen. The mean accuracy was submitted to an Anova for repeated measures of model: 2 sexes x [2 conditions x 4 expressions x 4 intensities]. We observed an advantage for the recognition of dynamic expressions of happiness and fear compared to the static stimuli (p < .05). Analysis of interactions showed that expressions with intensity of 25 % were better recognized in the dynamic condition (p < .05). The addition of motion contributes to improve recognition especially in male participants (p < .05). We concluded that the effect of the motion varies as a function of the type of emotion, intensity of the expression and sex of the participant. These results support the hypothesis that dynamic stimuli have more ecological validity and are more appropriate to the research with emotions.

Acciones de promoción de la salud organizacional y su relación con variables estructurales y el bienestar de los trabajadores: análisis desde un modelo de organizaciones saludables

El bienestar de los trabajadores es un imperativo categórico para las organizaciones tanto por razones éticas como por razones de competitividad. La creación de organizaciones o entornos laborales que promuevan el bienestar de los trabajadores constituye un gran reto para las organizaciones y un ámbito de estudio académico. En el presente artículo se describe la relación que existe entre un conjunto de factores organizacionales y su impacto en el bienestar de un grupo de trabajadores, expresado a través del engagement, la satisfacción con el trabajo y la ansiedad relacionada con el trabajo. Para probar las relaciones hipotetizadas se empleó un modelo de ecuaciones estructurales y los resultados obtenidos señalan que las acciones de promoción de la salud organizacional tiene un impacto significativo en los valores culturales y en la adopción de prácticas organizacionales

Sustainable urban criteria in the urban periphery of Guadalajara

The study of the growth of large cities, in the urban periphery or the peri-urban areas specifically, it relates to environmental degradation due to urbanization, if it is estimated that since 2008 more than half of the world population living in urban areas, this sector is affected as it presents overcrowding, segregation and deterioration of physical conditions, which will impact on the social aspects within localities. This great urban growth has usually developed with the lack of environmental planning.So it is necessary to include urban development, guidelines towards environmental conservation and rehabilitation of the territory. The future of cities will depend largely on the actions taken now. As urban development inevitably requires planning urban settlements through sustainable development so as to provide alternative technologies, based on the reality of Latin American countries.In the peripheral area of the Metropolitan Zone of Guadalajara, is taken as a case study of the town of La Venta del Astillero, which by its nature allows access and functionality to develop a set of criteria and indicators to urban sustainability, which can take as a model for other communities in the urban periphery.
