Racial and spatial interaction for neighborhood dynamics in Chicago

We look at at the empirical validity of Schelling’s models for racial residential segregation applied to the case of Chicago. Most of the empirical literature has focused exclusively the single neighborhood model, also known as the tipping point model and neglected a multineighborhood approach or a unified approach. The multi-neighborhood approach introduced spatial interaction across the neighborhoods, in particular we look at spatial interaction across neighborhoods sharing a border. An initial exploration of the data indicates that spatial contiguity might be relevant to properly analyse the so call tipping phenomena of predominately non-Hispanic white neighborhoods to predominantly minority neighborhoods within a decade. We introduce an econometric model that combines an approach to estimate tipping point using threshold effects and a spatial autoregressive model. The estimation results from the model disputes the existence of a tipping point, that is a discontinuous change in the rate of growth of the non-Hispanic white population due to a small increase in the minority share of the neighborhood. In addition we find that racial distance between the neighborhood of interest and it surrounding neighborhoods has an important effect on the dynamics of racial segregation in Chicago.

Pedagogías lúdicas para la paz: una mirada a las percepciones de violencia en niñas y niños de Ciudad Bolívar

En esta investigación indagué sobre la influencia del entorno en las concepciones sociales que se forma el sujeto (en este caso los niños) frente a distintas realidades y situaciones de su cotidianidad, los elementos que están presentes en sus formas de interacción más cotidianas, y hasta dónde herramientas como la educación con enfoque lúdico y social pueden o no modificar prácticas y percepciones en el individuo. Para ello, la investigación se centra en tres conceptos claves: violencia, educación, y paz. Y hacia el final del trabajo se planta una propuesta de currículo para una educación para la paz basada en la formación de la persona social, desde el enfoque de la paz negativa.
