This study investigated the role of fatalism as a cultural value orientation and causal attributions for past failure in the academic performance of high school students in the Araucania Region of Chile. Three thousand three hundred and fourty eight Mapuche and Non-Mapuche students participated in the study. Consistent with the Culture and Behavior model that guided the research, the test of causal models based on the analysis of structural equations show that academic performance is in part a function of variations in the level of fatalism, directly as well as indirectly through its influence in the attribution processes and failure-related emotions. In general, the model representing the proposed structure of relations among fatalism, attributions, and emotions as determinants of academic performance fit the data for both Mapuche and non-Mapuche students. However, results show that some of the relations in the model are different for students from these two ethnic groups. Finally, according to the results from the analysis of causal models, family SES appear to be the most important determinant of fatalism.

The Self-Appraisal Questionnaire (SAQ) is a self-report that predicts the risk of violence and recidivism and provides relevant information about treatment needs for incarcerated populations. The objective of the present study was to evaluate the concurrent and predictive validity of this self-report in Spanish offenders. The SAQ was administered to 276 offenders recruited from several prisons in Madrid (Spain). SAQ total scores presented high levels of internal consistency (alpha = .92). Correlations of the instrument with violence risk instruments were statistically significant and showed a moderate magnitude, indicating a reasonable degree of concurrent validity. The ROC analysis carried out on the SAQ total score revealed an AUC of .80, showing acceptable accuracy discriminating between violent and nonviolent recidivist groups. It is concluded that the SAQ total score is a reliable and valid measure to estimate violence and recidivism risk in Spanish offenders.

Introducción: el bajo peso al nacer (BPN) es un factor de riesgo para desarrollar obesidad en la vida adulta. Objetivo: evaluar diferencias en la composición corporal de niños de entre 8 y 10 años de edad con y sin antecedente de BPN. Métodos: fue un estudio observacional, transversal comparativo. Participaron 112 niños (95 con adecuado peso al nacer [APN] y 17 con BPN). Se realizó antropometría (peso, talla, circunferencias de cintura y cadera, pliegue cutáneo de tríceps [PCT] y subescapular [PCSE]). Resultados: se encontró una prevalencia combinada del 41% para sobrepeso y obesidad en ambos grupos de estudio. El porcentaje de grasa corporal total fue menor en las niñas con BPN (no significativo); sin embargo, el indicador PCT-PCSE fue significativamente más alto (p = 0,04) que el de las niñas con APN. En contra de lo esperado, al estratificar según porcentaje de grasa y peso al nacer, se encontró que el grupo con BPN presentó un porcentaje de grasa bajo (p < 0,05) en comparación con el grupo de APN, siendo 6 veces mayor la posibilidad de que un niño con BPN presente porcentaje de grasa total bajo a esta edad. Conclusiones: a estas edades no se encontró mayor porcentaje de grasa en el grupo con BPN en comparación con el de APN; sin embargo, las niñas con BPN presentaron mayor deposición de grasa troncal que las de APN. La deposición de grasa es un indicador que hay que considerar, y no únicamente el índice de masa corporal, en la evaluación nutricia infantil.
