Participants ’ executive functions were assessed with the Spanish adaptation of the Behaviour Rating Inventory of Executive Function (BRIEF ® 2). For the assessment of their emotional and behavioural problems, the Spanish adaptation of the Assessment System for Children and Adolescents (SENA) was used. The results revealed an improvement in initiative and task supervision. After the intervention, the minors reported having fewer problems with their classmates and fewer symptoms related to traumatic events. According to the educators, those minors also presented better integration and social skills, a greater willingness to study, less isolation, less symptoms of depression, fewer emotional problems and a higher level and variety of personal resources.

To evaluate the mineral grain contents in a pigmented corn collection from Oaxaca, Mexico, 57 accessions from indigenous communities and three commercial varieties were grown in two cultivation locations. A random grain sample was obtained from the crops, and the Cu, Fe, Mn, Zn, P, Mg, K, Ca, Na, and S contents were quantified using an optical emission spectrophotometer with inductively coupled plasma (ICP-OES). The cropping localities significantly influenced the mineral contents. Likewise, significant differences were observed between accessions, groups of pigmented grains, and accession-locality interactions except for zinc. The groups of pigmented grains interact with Cu, Fe, Ca, and Na in the environment. Among the accessions, high variation was observed in all elements except for Zn. The results show that a breedin...

En este trabajo se evaluó la heterosis en capsaicinoides y características agromorfológicas de híbridos interpoblacionales de chile de diferente origen geográfico. Se evaluaron agromorfológicamente ocho progenitores y nueve híbridos, y a la cosecha de frutos se determinó el contenido de capsaicina (CAP) y dihidrocapsaicina (DH) por cromatografía de gases. Se determinaron diferencias significativas (P < 0.01) entre progenitores e híbridos para días a floración, fructificación y maduración de frutos, altura de planta, número y peso de frutos por planta, y longitud y ancho de frutos. Se determinó heterosis tanto positiva como negativa respecto al progenitor medio y mejor progenitor en variables fenológicas, y he...

El objetivo del estudio fue evaluar el contenido de minerales en semilla de una colección de 67 poblaciones nativas de frijol originarias de cuatro regiones de Oaxaca: Valles Centrales, Sierra Norte, Sierra Sur y Mixteca. Las poblaciones se sembraron en San Agustín Amatengo, Oaxaca, en primavera-verano 2014 bajo condiciones de temporal (secano), en un diseño de bloques completos al azar con cuatro repeticiones; a la cosecha se obtuvo una muestra compuesta de 500 g de semilla por accesión. La evaluación del contenido de minerales se hizo mediante espectrofotometría de absorción atómica y ultravioleta visible, con base en estándares de referencia. El análisis de varianza...

The algorithm is of heuristic nature and it uses as unique evidence for clustering the identification of cognate named entities between both sides of the comparable corpora. One of the main advantages of this approach is that it does not depend on bilingual or multilingual resources. However, it depends on the possibility of identifying cognate named entities between the languages used in the corpus. An additional advantage of the approach is that it does not need any information about the right number of clusters; the algorithm calculates it. We have tested this approach with a comparable corpus of news written in English and Spanish. In addition, we have compared the results with a system which translates selected document features. The obtained results are encouraging.
