In this work we define iterated change operators that do not obey the primacy of update principle. This kind of change is required in applications when the recency of the input formulae is not linked with their reliability/priority/weight. This can be translated by a commutativity postulate that asks the result of a sequence of changes to be the same whatever the order of the formulae of this sequence. Technically then we end up with a sequence of formulae that we have to combine in order to obtain a meaningful belief base. Belief merging operators are then natural candidates for this task. We show that we can define improvement operators using an incremental belief merging approach. We also show that these operators can not be encoded as simple preorders transformations, contrary to most iterated revision and improvement operators.

El objetivo de este estudio fue analizar la relación entre el desarrollo de las necesidades psicológicas básicas y las creencias implícitas de habilidad en alumnado de Educación Secundaria. La muestra estuvo formada por un total de 97 estudiantes de Educación Secundaria, con edades comprendidas entre los 13 y los 15 años (edad media = 13.32 ± 0.62 años) a los que se les aplicaron los cuestionarios de apoyo a las necesidades psicológicas básicas y creencias implícitas sobre la habilidad en sus clases de Educación Física. Los resultados no encontraron diferencias significativas en las variables de necesidades psicológicas básicas y de creencias implícitas de habilidad en función del género de los estudiantes. Por otro lado, la creencia de entidad correlacionó positivamente con el apoyo a las relaciones sociales, mientras que la creencia incremental correlacionó positivamente con el apoyo a la competencia y las relaciones sociales. Estos resultados pueden servir de referencia a profesores de Educación Física a la hora de establecer estrategias en función del género que favorezcan la satisfacción de las necesidades psicológicas básicas de sus estudiantes.AbstractThe aim of this study was to know the levels of basic psychological needs, and implicit beliefs of ability in secondary stage students. The sample was made up of a total of 97 students of Secondary Education, with ages between 13 and 15 (mean age = 13.32 ± 0.62 years) to whom the questionnaires to support basic psychological needs and ability beliefs were applied in Physical Education lessons. The results found no significant differences in the variables of basic psychological needs and implicit beliefs of ability based on the gender of the students. On the other hand, entity belief positively correlated with support for social relationships, while incremental belief positively correlated with support for competition and social relationships. These results can serve as a reference for physical education teachers when establishing gender-based strategies to meet the basic psychological needs of their students.

We study how belief merging operators can be considered as maximum likelihood estimators, i.e., we assume that there exists a (unknown) true state of the world and that each agent participating in the merging process receives a noisy signal of it, characterized by a noise model. The objective is then to aggregate the agents' belief bases to make the best possible guess about the true state of the world. In this paper, some logical connections between the rationality postulates for belief merging (IC postulates) and simple conditions over the noise model under consideration are exhibited. These results provide a new justification for IC merging postulates. We also provide results for two specific natural noise models: the world swap noise and the atom swap noise, by identifying distance-based merging operators that are maximum likelihood estimators for these two noise models.
