Analysis of mediation and reciprocal effects of changes in weight, self-esteem, and exercise in a behavioral weight loss treatment

Improving the treatment of obesity remains a critical challenge. Several health behaviour change models, often based on a social-cognitive framework, have been used to design weight management interventions (Baranowski et al., 2003). However, most interventions have only produced modest weight reductions (Wadden et al., 2002) and socialcognitive variables have shown limited power to predict weight outcomes (Palmeira et al., 2007). Other predictors, and possibl alte nati e e planatory models, are needed to better understand the mechanisms by which weight loss and other obesity treatment-outcomes are brought about (Baranowski, 2006). Self-esteem is one of these possible mechanisms, because is commonly reported to change during the treatment, although these changes are not necessarily associated with weight loss (Blaine et al., 2007; Maciejewski et al., 2005). This possibility should be more evident if the program integrates regular exercise, as it promotes improvements in subjective well-being (Biddle & Mutrie, 2001), with possible influences on long-term behavioral adherence (e.g. diet, exercise). Following the reciprocal effects model tenets (Marsh & Craven, 2006), we expect that the influences between changes in weight, selfesteem and exercise to be reciprocal and might present one of the mechanisms by which obesity treatments can be improved.

The Pedagogical Congresses of Portuguese Secondary Teaching : the participation of female teachers (1927-1928)

This paper was written within the context of the research project “The development of teacher’ associative organizations and unionism (1889-1990)” funded by the Fundação para a Ciência e Tecnologia (Foundation for Science and Technology). Five important congresses about secondary education were organized in Portugal between 1927 and 1931. These congresses served to claim the rights of teachers and the consolidation of the class, as well as to promote the discussion of scientific and pedagogical problems. In these congresses, the presence of female teachers was residual. However, the few teachers who participated had a significant contribution to the definition of secondary education during the following decades. Among other issues, it contributed to the discussion of female education and to analyze the importance of Biology and Physical Education in high schools. This paper presents the analysis of the minutes of the 1927s and 1928s Congresses. This analysis allowed the assessment of the important role played by a group of teachers to define, at the end of the first third of the 20th century, the future guidelines of Portuguese secondary education. It also reported that these teachers were pioneers who opened the way for the increasing number of teachers in secondary education during the 20th century.
