Having achieved the coverage challenges following compulsory policies and a financing system via demand subsidy conditioned to enrollment and attendance, but faced with the scenario of school segregation, Chile has set itself the goal of advancing towards the right to an inclusive education and of quality. In this article we identify and analyze three critical nodes that affect the possibilities of achieving this goal: a) a tension between the logic of integration and educational inclusion, b) a market-based model that does not consider public values, and c) a new educational architecture, based on the logic of individual accountability, which places the possibility of educational improvement in individual incentive systems tied to the achievement of high performance tests. We discuss the need to address and unlock these nodes through transdisciplinary research.
Although there is growing interest in studying the long‐ignored relationship between stratification and race in Chile, racial bias in person perception remains unknown. We hypothesize that the segregation of the Chilean school system generated a prestige order in which pupils are differentiated by status characteristics according to the type of school they attend, and that these evaluations are based on racial traits. To test this hypothesis, we study whether facial appearance is sufficient to impute the type of school a pupil is attending, and whether these categorizations evoke different status evaluations of wealth and morality based on race. Results confirm that participants’ perceptions of facial appearance allow them to situate pupils in the Chilean social structure. Faces categorized as studying at different types of schools varied in their perceived wealth. However, the relationship between moral traits and types of schools was weak. We also found evidence of racial bias in the participants’ perceptions of pupils’ faces: faces categorized as enrolled in municipal schools (low status) were judged with Amerindian or mestizo racial traits, while faces categorized as attending private fee‐paying schools (high status) were judged with white racial traits. We did not find a relationship between race and morality.
The condition of unpaved roads is commonly assessed by using qualitative distress measures. Some methods do not consistently consider the relative effect of multiple defects on road condition, or their application is limited to the conditions under which they were developed. In 2007, the Ministerio de Obras Públicas of Chile and a private consultant developed the Modelos de Deterioro de Caminos No Pavimentados study. The scope of the study was to gain experience with and understanding of unpaved road behavior. The main goal of the study was to develop and validate a method for evaluating unpaved road condition by using objective measures of distress, drainage, and profile characteristics. The scope was to design a versatile tool that was applicable to any location, followed a simple procedure, and used cost-effective survey techniques. The proposed approach is to define condition models from a questionnaire administered to a professional panel by applying the Delphi method. As a result of the study, equations representing the unpaved condition index (UPCI) and condition limits were developed for unbound gravel, stabilized gravel, and earth roads subject to three climates: dry, Mediterranean, and humid. UPCI equations and condition limits were validated successfully; the method to assess unpaved road conditions was reliable and versatile.
Abstract. Sociological research shows that friendship and partner choice tend to reveal a bias toward social similarity. These relations are ruled by the so called "proximity principle" which states that the more similar two individuals are, the more likely they will become friends. However, proximity, similarity or friendship are concepts with blurred edges and grades of membership (acquaintances, friends, couples). Therefore, in order to model the friendship dynamics we work on an Agent-Based Model that already manages the social relationships, together with demographics and evolutionary crossover. To introduce these theoretical concepts we decided to fuzzify the system, explaining the process in detail. Thus, we end up with fuzzy sets and operations, a fuzzy friendship relationship, and a logistic function for its evolution.
