Miles e Snow’s configurational theory has received a great deal of attention from many investigators. Framing the Miles e Snow Typology with the organizational configuration concept, the main purpose of this paper is to make an empirical evaluation of what configurational theories postulate: higher organizational performance is associated to the resemblance to one of the ideal types defined. However, as it is often assumed that an organization can increase performance by selecting the adjustable hybrid type to its own exogenous environment, the relation between the organization’s effectiveness and the hybrid configuration alignment to the respective specific environment types was also analyzed. The assumption of equifinality was also considered because the configurational theory assumes that all the ideal types can potentially achieve the same performance level. A multiple regression model was made to confirm if the misfit related to the ideal and hybrid types has significant impact on the organizational effectiveness. The analysis of variance and the Kruskal-Wallis test were used to verify the equality of performance between the different organization types. In short, the empirical results obtained confirm what is postulated in the theory.

The relation between weight status (Body Mass Index - BMI), weight perception and subjective wellbeing remains unclear. Several studies conclude that discrepancies can be found between weight status and weight perception, among children and adolescents. The present study aims at investigating the associations between subjective wellbeing and individual characteristics, among children and adolescents. The sample included 1200 children and adolescents (51.7 % girls, aged 9 to 17). Their mean age was 12.55 years (SD = 1.61). The questionnaire was completed in school context, asking about the subjective wellbeing, use of self-regulation, eating behavior awareness/care, weight perception and sociodemographic questions such as age, gender and BMI. The study found a strong association between BMI and weight perception, although subjective wellbeing was better explained by weight perception than by BMI. Eating awareness and self-regulation also played an important role in subjective controlling for age and gender. Age and gender interfere in the relation between subjective wellbeing and other variables. The multiple regression model is more robust and explicative for girls and older children. Psychological factors related to weight, such as weight perception, self-regulation and eating awareness have a stronger explicative impact in subjective wellbeing compared to physical aspects, such as Body Mass Index. The relation between subjective wellbeing and weight is influence by age and gender.
