RESUMEN

The effects of family of origin violence and intimate partner violence have been extensively documented; however, very few studies have examined the interaction with emotion regulation strategies. Thus, the objective of this research was to analyze whether different types of emotion regulation strategies, both adaptive and maladaptive, mediate the relationship between family of origin violence and intimate partner violence in the Mexican population. A total of 838 participants (45.9% men and 54.1% women) responded to instruments addressing family of origin violence, emotion regulation strategies, and intimate partner violence. The results revealed that both structural models were significant. For women, the model showed an adequate fit X2 (11, N = 838) = 22.75, p = .288, GFI = .95, AGFI = .91, NFI = .98, CFI = .97, RMSEA = .05. Likewise, we found similar indexes for men X2 (11, N = 838) = 28.20, p = .348, GFI = .97, AGFI = .93, NFI = .97, CFI = .95, RMSEA = .04. Specifically, the direct effects of adaptive strategies on intimate partner violence were statistically significant. Meanwhile, the direct effects of family of origin violence on maladaptive emotion regulation strategies were significant, as were the direct effects of maladaptive strategies on intimate partner violence. In turn, the indirect effects of family of-origin violence were significantly related to intimate partner violence via maladaptive emotion regulation strategies. In addition, the results clearly showed that men reported higher levels of aggression against women. Finally, regarding the selection of emotion regulation strategies, while women employed more adaptive emotion regulation, men showed a more definite tendency to use maladaptive emotion regulation.

RESUMEN

Resumen La violencia en el noviazgo es un fenómeno multifactorial que requiere de estudios que profundicen respecto a los efectos que tienen las creencias culturales en el comportamiento tanto del agresor como de la víctima. Teniendo esto en cuenta, el objetivo de la presente investigación fue determinar la relación entre las creencias acerca de la violencia y la prevalencia de la violencia en el noviazgo. Para ello, se contó con una muestra de 420 estudiantes de dos universidades públicas mexicanas que respondieron el Inventario de creencias acerca de la violencia hacia la esposa, el Inventario de conflictos en las relaciones de noviazgo, y un cuestionario de información sociodemográfica. Los datos recolectados fueron examinados por medio de un análisis de correlación canónica, y los resultados mostraron que el modelo en general fue estadísticamente significativo (Wilks X = .654, F(20, 677.54) = 4.626,p < .05); que el tamaño del efecto del modelo general fue de .346, lo que indica que este explicó el 34.6 % de la varianza compartida por los dos conjuntos de variables; y que, específicamente en la primera función, el coeficiente de mayor magnitud fue el de la variable de justificación de la violencia (r2 s = 76.2; h 2 = 90.0), seguido por la del apoyo que se le puede brindar a la víctima (r2 s = 57.1; h2 = 94.5).

Abstract Dating violence is a multifactorial phenomenon that requires in-depth studies regarding the effects that cultural beliefs have on the behavior of both the aggressor and the victim. With this in mind, the objective of this research was to determine the relationship between beliefs about violence and the prevalence of dating violence. To this end, a sample of 420 students from two Mexican public universities answered the Inventory of Beliefs about Wife Violence, the Inventory of Conflicts in Dating Relationships, and a sociodemographic information questionnaire. The data collected were examined through a canonical correlation analysis, and the results showed that the overall model was statistically significant (Wilks X = .654, F (20, 677.54) = 4.626, p < .05); that the effect size of the overall model was .346, indicating that it explained 34. 6 % of the variance shared by the two sets of variables; and that, specifically in the first function, the coefficient of greatest magnitude was that of the variable of justification of the violence (r2 s = 76.2; h2 = 90.0), followed by that of the support that can be given to the victim (r2 s = 57.1; h2 = 94.5).

Specifically, the direct effects of adaptive strategies on intimate partner violence were statistically significant. Meanwhile, the direct effects of family of origin violence on maladaptive emotion regulation strategies were significant, as were the direct effects of maladaptive strategies on intimate partner violence. In turn, the indirect effects of family of-origin violence were significantly related to intimate partner violence via maladaptive emotion regulation strategies. In addition, the results clearly showed that men reported higher levels of aggression against women. Finally, regarding the selection of emotion regulation strategies, while women employed more adaptive emotion regulation, men showed a more definite tendency to use maladaptive emotion regulation.

RESUMEN

Food habits of the white-tailed deer, Odocoileus virginianus (Artiodactyla: Cervidae) in Nanchititla Natural Park, Mexico. White-tailed deer is a species with a large behavioral plasticity and adapta- tion to different habitats, including their food habits. This study was conducted with the aim to determine the food habits of this species in the cloud (BMM) and pine-oak (BPE) forests. Deer scats and plant samples were obtained following standard methods, from Sierra Nanchititla Park in the State of Mexico, from June 1990 to May 1992. A total of 104 deer pellet-groups were collected, and histological analysis for herbivores was used and compared with stock samples of plant tissues collected from the study area. We applied the Spearman correlation and Morisita index to determine alimentary preference. The results showed that the deer consumes 79.44% of plant species from BMM and 20.56% of the BPE. There is a selectivity tendency for 12 of the 14 plant species located in the BMM, while for BPE no tendency was observed. Key species that are part of the elemental diet of the deer in these areas were: Acalypha setosa, Smilax pringlei, Psidium sartorianum and Dendropanax arborea. The consumption of plants did not differ significantly between the dry and rainy seasons in terms of biological form, however, during the dry season there is a tendency to consume trees, and by the end of the rainy season to consume herbs. The data indicate that the deer can be selective with BMM plants, while for the BPE tends to be opportunistic.

El venado cola blanca es una especie con una gran plasticidad conductual y de adaptación en diferentes hábitat. En el Parque Sierra Nanchititla en el Estado de México se realizó un estudio para determinar los hábitos alimentarios en el bosque mesófilo de montaña (BMM) y bosque de pino-encino (BPE). De junio 1990 a mayo 1992 se recolectaron 104 muestras de excremento de venado en las dos zonas de estudio. Aplicamos el índice de Morisita y la correlación de Spearman para determinar la preferencia alimentaria. Se utilizó el análisis histológico de heces fecales para herbívoros las cuales se compararon con muestras de tejidos vegetales de plantas de la zona de estudio. Los resultados muestran que consume el 79.44% de especies vegetales del BMM y 20.56% del BPE. Existe cierta tendencia en la selectividad de 12 de las 14 especies de plantas localizadas en el BMM, mientras que para el BPE no se aprecia tal tendencia. Las especies clave que for- man parte de la alimentación elemental del venado fueron: Acalypha setosa, Smilax pringlei, Psidium sartorianum y Dendropanax arborea. El consumo de plantas no varió sig- nificativamente entre la época seca y lluviosa en función de la forma biológica (X2=12, p=0.21). Sin embargo, durante la época seca existe cierta tendencia a consumir árboles y a finales de la época de lluvia a consumir hierbas (Z=1.61, p=0.95). Los datos indican que el venado puede ser selecti- vo con plantas del BMM, mientras que para el BPE tiende a ser oportunista.
