In this thesis I investigate the relationship between the built environment and the residential segregation of immigrants at the building level. I use micro-data that includes the exact address of all the foreign and native population in Barcelona, combined with geometric indicators for urban shape at the block level. Using these data, I construct measures of segregation over time to evaluate t...

Pictorial competence , which refers to the many factors involved in perceiving, interpreting, understanding, and using pictures, develops gradually over the first few years of life. Although experience is not required for accurate perception of pictures, it is necessary for understanding the nature of pictures. Infants initially respond to depicted objects as if they were real objects, and todd...

We present results of opinion dynamics simulations based on the emotion/information/opinion (E/I/O) model, applied to a strongly polarized society. Under certain conditions the model leads to metastable coexistence of two subcommunities (supporting each of the opinions) of comparable size – which corresponds to bipartisan split found in many real world communities. Spurred by the recent breakdo...

In this paper highlights that audiovisual speech perception is not all autonomous and that lexical semantic context and word meaning can influence McGurk fusion and the rate of fusion responses too. Sentence context can actually diminish McGurk fusion rate when semantic cueing from the context biases against the fusion expected. However, it did not block the fusion entirely even when the cue st...

  Background: Health status is an individual’s relative level of wellness and illness. Self-Perceived Health (SPH) is a single item considered as a health indicator for national and international survey. The aim of this study was to evaluate the SPH measure and its determinants in a National sample of Iranian children and adolescents.   Materials and Methods:  This National study was performed...

Background This prototype, self navigated, free breathing 3D sequence acquires continuous ECG-segmented radial views of the heart with 100% scan efficiency, without a beam-navigator, and without the time expense of scanning within a range of diaphragmatic positions. The reconstructed image is respiratory motion corrected based on the inferior-superior motion of the left ventricular blood pool. ...

Understanding whether the gradient in children’s health becomes steeper with age is an important first step in uncovering the mechanisms that connect economic and health status, and in recommending sensible interventions to protect children’s health. To that end, this paper examines why two sets of authors, Chen et al. [Socioeconomic status and health: Do gradients differ within childhood and a...
