Reproduction is not restricted to the biological; it is also a complex and dynamic social process. The objective of this paper is to analyze the decision and planning of children as part of the reproductive process in men. Methodologically, a qualitative research was made. The analysis includes in-depth interviews with 30 parents between 20 and 45 years, of medium socio-economic level in México. The results show that the reproductive process incorporates family formation negotiated with their couple the marriage until they had economic potential. In some cases, their decision hastened because the couple was pregnant. The planning was not contemplated but when getting the news, they accept it and get involved in the process, while others see it as a conflict.

En junio de 2000 el Departamento Nacional de Estadística de Colombia adopto una nueva definición de medición de desempleo siguiendo los estándares sugeridos por la organización Internacional del Trabajo (OIT). El cambio de definición implico una reducción de la tasa de desempleo en cerca de dos puntos porcentuales. En este documento contrastamos la experiencia colombiana con otra experiencias internacionales, y analizamos las implicaciones empíricas y teóricas de este cambio de definición usando dos tipos de estimaciones cuantitativas: en la primera se contrasta las principales características de las diferentes categorías clasificadas según la definición nueva y vieja de desempleo (empleado, desempleado y fuera de la fuerza laboral) usando el algoritmo EM; en la segunda se pone a prueba la implicación del desempleo estructural y su relación con el perfil educacional de personas desempleadas y las características teóricas que enfrentan los estándares de la OIT en la definición de empleo.

The present study contributes to the literature on the Job Demands-resources model in the italian school context. the aim of this paper is to examine how the interaction between work-family conflict (i.e., a typical job demand) and opportunities to learn and to develop and self-efficacy (i.e., typical job and personal resources, respectively) affect the core dimensions of burnout (exhaustion and depersonalization) and work engagement (vigor and dedication). Hypotheses were tested with a cross-sectional design among 143 teachers of a junior high school in the north of Italy. Results of moderated multiple regression analysis partially supported the hypotheses as the opportunities to learn and to develop buffered against the aversive effects of work-family conflict on depersonalization, whereas self-efficacy moderated the relationship between work-family conflict and vigor. From a practical viewpoint, our findings suggest that opportunities to learn and to develop and self-efficacy are important re- sources that help teachers to reduce the negative effects related to work-family conflict.
