Evaluación de las distritaciones electoralesen México de 1996 y 2005: una propuesta de indicadores

La tecnología reviste características de neutralidad, eficiencia, transparencia y regularidad. Factores que hoy día resultan relevantes para realizar procesos electorales confiables. Las redistritaciones electorales en México 1996 y 2005 resultan casos paradigmáticos en relación a la cristalización de la tecnología como una mediación para la construcción de acuerdos entre los partidos y las autoridades electorales. Se ofrecen cinco indicadores para comparar ambos procesos de distritación

Evaluación de las distritaciones electoralesen México de 1996 y 2005: una propuesta de indicadores

Technology has characteristics like neutrality, efficiency, transparency and regularity. All of them are important factors to be considered in the organization of electoral process. The electoral redistricting of 1996 and 2005 in Mexico are two examples of the technology as a political mediation useful to the construction of agreements between political parties and electoral authorities. We offer five empirical indicators to compare both cases

A prospective randomized controlled trial of an interpersonal violence prevention program with a Mexican American community

Using methods of community-based participatory research, a prospective randomized controlled trial of a violence prevention program based on Latino cultural values was implemented with elementary school children in a Mexican American community. Community members participated in intervention program selection, implementation, and data collection. High-risk students who participated in the program had greater nonviolent self-efficacy and demonstrated greater endorsement of program values than did high-risk students in the control group. This collaborative partnership was able to combine community-based participatory research with a rigorous study design and provide sustained benefit to community partners

Frequency versus magnitude of reinforcement: New data with a different procedure

Two pigeons, with previous exposure to concurrent schedules, were submitted to 29 sessions of 8 hours each with concurrent variable-interval variable-interval schedules in which reinforcement parameters changed from session to session. In the first nine sessions reinforcement durations were equal in both schedules while reinforcement frequencies varied; in Sessions 10 through 18, both frequency and duration of reinforcement were varied; in Sessions 19 through 29, only reinforcement duration was varied. Results with this different procedure confirm previous findings that behavior is more sensitive to changes in reinforcement frequency than to reinforcement magnitude
