Key factors in levels of public satisfaction with urban waste collection in a northern Spain city

Levels of public satisfaction among the inhabitants of Burgos with their urban waste collection service are analyzed by comparing satisfaction levels in 2006 and in 2016, as well as the homogeneity of these satisfaction levels in the different areas of the city into which it was divided in 2016. To do so, an empirical exploratory analysis is completed on a representative sample of the population. A regression model is used to identify the significant factors from among all of the factors in the analysis. Then, a predictive model is defined that increases the probability of successful decision-making among the managers responsible for this service. The results provide support for one of the starting hypotheses, considering the daily collection of organic waste, the daily collection of selective waste, the capacity of organic waste containers, the proximity of organic waste containers, the cleanliness of pavements and the cleanliness of walkways as significant factors in the evaluation of public satisfaction. With these factors, the predictive model offers us a certainty index of 66.26% in its predictions.

Evaluation of the Effects of the Sexual Education Programme SOMOS on Sexual Experience and Attitudes of Adolescents Towards Sexuality // Evaluación de los efectos del Programa de Educación Sexual SOMOS sobre la experiencia sexual y las actitudes hacia la sexualidad de adolescentes

The effects of the SOMOS Sexual Education Programme on attitudes towards sexuality in general and towards masturbation in particular, as well as the possible impact of that programme on the sexual experiences of pupils are studied. The investigation takes a sample of 123 adolescents enrolled in the 3rd year of Compulsory Secondary Education, aged between 13 and 17 years old. A design of repeated pre-test/post-test measurements was used with three experimental groups (71 students) and two control groups (52 students). To do so, the evaluation instrument was administered before and after the educational int ervention (12 sessions). The results of T tests for related samples confirmed that the programme favours the development of positive attitudes towards sexuality, as well as a significant reduction in negative attitudes towards masturbation. Moreover, it was noted that the sexual experience of the students increased in a progressive way regardless of the group to which they belonged.
