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 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.

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.

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.

The aim of this study is to know the general condition of business communications regarding Corporate Social Responsibility (CSR) in large Mexican companies, and identify the significant differences in terms of a set of indicators and in comparison with three different operational levels. Specifically, based in a relevant previous research work by Maignan and Ralston (2002) and analyzing the content of 150 Mexican business websites as a sample frame, the study evaluates the differences in a set of CSR indicators divided in principles, processes and stakeholder issues. And then, compare these indicators among the national, international and multinational level by utilizing the statistical Chi-square test. The main findings suggest a high prevalence of corporate communications regarding social responsibilities in large Mexican companies, especially from those that operate on a multinational level and coming from abroad. The performance-driven principle was found to be the main motivation behind CSR communications for all levels; quality programs were the most employed CSR process in order to build a good citizenship image; and the stakeholder issues related to shareholders and the indicator of service/product quality from the customers group, were those found more significantly similar among the groups.

The aim of this study is to determine the differences between types and technological means by which Mexican high school students perform cyberbullying. The effects to perform the role of aggressor and victim in the traditional bullying were also established in the intensity of the reports of cyberbullying. It was used a random cluster sampling with 278 students selected from four high schools, to which they were given two instruments designed expressly for measuring the frequency of types of cyberbullying and the use of technological means for its realization, as well as the frequency of bullying respectively. Results showed that denigration, harassment and exclusion were reported significantly more strongly than the other types of cyberbullying, and that the most frequently used technological medium were social networks. It was also found that performing the role of aggressor (R 2 =.44) or victim (R 2 =.37) explained a significant portion of the variance of cyberbullying reports. It was concluded that cyberbullying is a phenomenon that can take various forms and it is related in a complex way with traditional bullying.

The aim of the study was to determine the effects of family dynamics and the practices of teachers, in relation to the frequency with which the mothers reported to participate in activities related to the education of the children. For this purpose, an evaluation was carried out in four public primary schools of a municipality in the Northwest of Mexico, serving a population of low level economic income. As part of the study, 170 mothers were selected by means of a nonprobabilistic sampling. By using simple linear regression it was found that family dynamics, and the practices of teachers to involve the parents in education, explain a significant part (R 2 = .67) of mothers reporting participation in the education of the children. It was concluded that both variables exert a positive influence in the involvement of mothers in education.
