The purpose of this research is to determine the degree of association between organizational culture and knowledge management. Using a quantitative and cross-sectional design, the Pearson correlation coefficient was used to assess the relationship between variables, as well as a hierarchical multiple regression in order to measure the potential impact of organizational culture on knowledge management. To test some hypotheses, a sample of 39 tequila business organizations from the state of Jalisco was obtained, whose results provided empirical evidence that organizational culture can associate and explain to knowledge management.

The effects of the presence of challenging behavior problems, parental conflict and violence in the community were determined by the probability of occurrence of bullying behaviors in elementary students. 664 students participated in the study, of whom 80 (12.04%) were identified as aggressors. 80 students with no reports of attacks were later selected randomly for comparison. Using logistic regression, it was found that the variables studied manifest significant differences between the student groups with and without aggressive behavior toward peers (R 2 = .39). Challenging behavior (OR = 7.83), parental conflict (OR = 3.77) and Community Violence (OR = 5.36) increase the probability of belonging to the group of aggressors. We conclude that it is necessary to analyze the bullying from an ecological framework that considers variables located in the contexts in which individuals interact. ResumenSe buscó establecer la relación de la presencia de conductas desafiantes, conflictos entre padres y violencia en la comunidad con la probabilidad de ocurrencia de comportamientos de intimidación en estudiantes de primaria. En este estudio participaron 664, de los cuales 80 (12.04%) fueron identificados como agresores; posteriormente se incluyeron al azar 80 estudiantes sin informes de ataques como grupo control. Usando la regresión lógica, se encontró que las variables estudiadas manifiestan diferencias significativas entre los grupos de estudiantes con y sin comportamiento agresivo hacia los compañeros (R 2 = .39). El comportamiento desafiante (OR = 7.83), el conflicto parental (OR = 3.77) y la violencia comunitaria (OR = 5.36) aumentan la probabilidad de pertenecer al grupo de agresores. Concluimos que es necesario analizar el bullying desde un marco ecológico que considera variables ubicadas en los contextos en los que interactúan los individuos.

The purpose of this study is to identify groups of gifted university students that differ in their self-concept and achievement motivation. For this, 80 students who achieved scores of the 95th percentile or higher in the Raven's Progressive Matrices test were selected. Two groups were identified in terms of their social self-concept and the competitiveness-oriented achievement motivation variables. The first group (Protected) gathered 51 (63.7%) gifted students who exhibited high levels of social self-concept and a low level of competitiveness-oriented achievement motivation with respect to the second group (At-risk), which gathered 29 (36.3%) gifted students. It was concluded that Protected students possess affective resources that strengthen their social and academic development, whereas At-risk students' variables represent vulnerability factors.

RESUMEN El presente estudio se propuso evaluar la sustentabilidad empírica de un instrumento de medición de la responsabilidad social empresarial (RSE) en consumidores de México. Para ello, se seleccionó una muestra no probabilística de 436 estudiantes de una universidad pública, la cual fue dividida en dos submuestras (n = 218). Mediante un análisis factorial exploratorio y un análisis factorial confirmatorio, los resultados obtenidos demostraron la validez empírica del modelo. Se propone que al utilizar dicho instrumento se obtenga información empírica suficiente que sirva para la toma de decisiones estratégicas, así como para enriquecer y sustentar las ideas y teorías existentes sobre la RSE, muchas de las cuales no han sido validadas dentro del contexto latinoamericano. Es importante señalar que, debido a la naturaleza del tema y el tipo de escala, existe la posibilidad de cierta deseabilidad social en las respuestas del instrumento. Se concluye que el instrumento puede ser utilizado por otros investigadores para valorar de manera sustentable la RSE.
