Gender differences on sexual behaviour and school inputs: evidence from Bogota.

This thesis explores the correlation between school factors and the differentiated results on sexual behaviour between boys and girls in Bogota. A school stratified propensity score matching was performed to match each boy of the sample with the most similar girls in individual, household and school characteristics. A regression analysis was performed to estimate the correlation between the five school factors evaluated with four main outcomes: have had sexual intercourse, condom use in the last sexual intercourse, incidence of teenage childbearing and age at first intercourse. Boys - in relation to girls - begin earlier their sexual life, more of them reported have used condom in their last sexual intercourse and have a lower incidence of teenage childbearing. These differences are correlated with have reported the school as main source of knowledge about reproductive health and contraceptive methods, a larger proportion of teachers with a graduate or postgraduate degree, a larger proportion of teachers with a related pedagogy degree and to the average age of teachers in the school. The results suggest that the content of the message about sex that is delivered to girls at school is not complete or accurate and that the competences of the school teachers in charge of this task should be improved to reach equally boys and girls.

Relationship among children’s perception of parental relationship and parental empathy and prosocial behaviour during childhood

The objective of this work is to study if children’s perception of parental relationship and parental empathy can predict prosocial behaviour during childhood. The sample was composed of 934 Argentine children, aged 9 to 12, of middle socio-economical level. The participants completed Argentine scale of Children Perception of Parental relationship (richaud de Minzi, 2007), an Argentine adaptation of scale of Prosocial Behaviour (Caprara and Pastorelli, 1993) and a questionnaire to measure children’s perception of parental empathy (richaud de Minzi, 2006). structural equations modelling (sEM) analyses were conducted to explore our hypotheses. Six theoretical models fit the data very well. The results showed that parental styles of acceptance and pathological control impact on children prosocial behavior. Children’s perception of parental empathy was positively associated with children prosocial behavior. Finally, parental acceptance and pathological control were associated with children’s perception of parental empathy, but negligent parental behaviour did not.  

Liderazgo y poder: una aproximación desde la ecología

El trabajo de grado se desarrollará a partir del análisis del liderazgo y el poder como característica de éste, desde una visión ecológica, lo cual constituye un aspecto de gran importancia en los estudios de administración. Primero, se abordará el significado de liderazgo y la importancia que este representa dentro de las organizaciones, a través de la generación de procesos que llevan a la organización a su evolución y desarrollo. Posteriormente se abordará el tema de poder en relación con la comprensión del efecto que este puede tener sobre las interacciones que se dan entre las personas de la organización. Finalmente, se estudiará también desde la ecología, como el poder ejercido por los líderes puede influir en la forma en que estos agentes, es decir personas, procesos e interacciones, interactúan para movilizar a la organización. De esta forma, se asume el poder como un aspecto importante dentro del estudio del liderazgo, en cuanto éste puede afectar la forma en que las personas son lideradas al interior de la organización.
