Propiedades psicométricas de la Escala de Victimización Escolar entre Iguales (VE-I)
2018
<p>La violencia escolar entre iguales tiene graves consecuencias para las víctimas. La victimización puede ser directa, mediante agresiones físicas y verbales, y relacional mediante exclusión y rechazo social. El objetivo de este estudio fue analizar las propiedades psicométricas de la escala de Victimización Escolar entre Iguales (VE-I) que consta de 11 ítems relativos a diferentes formas de victimización. En este estudio participaron 1389 adolescentes (50.45% varones), de entre 11 y 15 años (M = 13.37, DE = 1.23). La estructura de la escala fue analizada mediante análisis factorial exploratorio y análisis factorial confirmatorio, por lo que se utilizaron dos submuestras diferentes.…
Maxillofacial and dental-related injuries from a Brazilian forensic science institute : victims and perpetrators characteristics and associated risk …
2020
Background Trauma due to external causes represents one of the greatest challenges for public health services in different regions around the world. This study aimed to determine the prevalence of facial trauma, associated risk factors, and classification of body injuries in individuals who underwent forensic examination in a Brazilian center. Material and Methods Data were collected at the Ceará State Forensic Medicine unit in a 12-year period. Sociodemographic data related to the etiological agent and lesions resulting from the bodily injury were recorded. Results Among 1,031 physical injury exams, physical aggression (p<0.001), male victims aged between 21 and 30 years (p<0.001), salarie…
When cooler heads prevail: peacemakers in a sports riot.
1999
Male sports fans (N = 74) were asked to estimate the likelihood that they would intervene in a crowd disturbance in an attempt to stop the fighting. They also completed a battery of measures that included their attitude toward law and order, fight history, the false consensus effect, impulsivity, psychopathy, sensation seeking, anger, physical aggression and identification with their favorite team. Law and order, body mass, anger and the false consensus effect were positively related to peacemaking whereas sensation seeking was negatively related. A multiple regression analysis yielded a solution that accounted for 32.3% of the variance with anger and attitude toward law and order emerging …
The forager's dilemma: food sharing and food defense as risk-sensitive foraging options.
2003
Although many variants of the hawk-dove game predict the frequency at which group foraging animals should compete aggressively, none of them can explain why a large number of group foraging animals share food clumps without any overt aggression. One reason for this shortcoming is that hawk-dove games typically consider only a single contest, while most group foraging situations involve opponents that interact repeatedly over discovered food clumps. The present iterated hawk-dove game predicts that in situations that are analogous to a prisoner's dilemma, animals should share the resources without aggression, provided that the number of simultaneously available food clumps is sufficiently la…
Prosocial and Aggressive Behavior Occurrence in Young Athletes: Field Research Results in Six European Countries
2020
Aggression and violence among youth are researched as social phenomena in sport. This paper was designed to determine the occurrence of these behaviors as well as prosocial behaviors among young athletes. The current paper is a research report aiming to detect the frequency of aggressive behavior, social exclusion, prosocial behavior and cohesion in the youth environment, the frequency of personal experience of peer violence or social exclusion, and to evaluate cross-national differences in terms of occurrence of these phenomena.The field research was conducted in six European countries (Austria, Bosnia and Herzegovina, Croatia, Italy, Lithuania, and Serbia) on a sample of 482 children aged…
Moral Disengagement in Youth Athletes: A Narrative Review
2022
The sports environment can be considered as a context characterized by interactions typical of social groups, where children have the chance to learn good values. Positive and negative behaviours in sports, also called prosocial and antisocial behaviours, have been studied according to a moral perspective, as has doping behaviour, taking into consideration the concept of moral disengagement. Moral disengagement in children has been associated with maladaptive behaviours later in life, even though it should disappear with growth. Concerning the sports environment, previous reviews on the topic have extensively illustrated the role of moral variables in sport and their relation to antisocial …
Terms of abuse as expression and reinforcement of cultures
2008
In this study terms of abuse are investigated in 11 different cultures, Spontaneous verbal aggression is to a certain extent reminiscent of the values of a certain culture. Almost 3000 subjects from Spain, Germany, France, Italy, Croatia, Poland, Great Britain, USA, Norway, Greece, and The Netherlands were asked to write down terms of abuse that they would use given a certain stimulus situation, and in addition, to give their rating of the offensive character of those terms. A total set of 12,000 expressions was collected. The frequencies of the expressions were established, and the total list of expressions was reduced to 16 categories. Results point to some etic taboos, like sexuality and…
Attitudes and motivation in the treatment of IPV : a case study of two intimately violent men
2017
This case study used qualitative content analysis to examine the cases of two intimately violent men. Both participated in a group intervention but experienced dramatically different outcomes. In the case of "Henri", the intervention was especially successful, but in the case of "Mikael" it was unsuccessful. The data of this study consisted of the video tapes of the men’s therapy sessions, and of the interviews of their spouses. The research questions were the following: 1) Were there changes in the men’s attitudes toward a) women, b) masculinity and c) violent behavior?, 2) How high was the men’s motivation for treatment and making changes in themselves? and 3) Did their attitudes and moti…
Effect of anosmia on the behavior of standard non-aggressive male mice opponents during agonistic encounters
1997
This study assessed whether the differences observed in a previous experiment [Martinez M, Salvador A, Simon VM (1994): Aggressive Behavior 20:441–451] in the behavior of isolated male mice over several agonistic encounters in which they confronted either an “anosmic” or an “intact” non-aggressive “standard opponent” were due to the differences in the behavior of the opponents themselves. Ethologically-inspired analysis was used to assess the behavior of the opponents during the first agonistic encounter. Anosmic opponents spent less time in social investigation and defense and more time in immobility than intact ones. These results suggest that the differences in the behavior of the oppone…
Behavioral changes over several successful agonistic encounters between male mice: Effects of type of “standard opponent”
1994
This study assessed whether two types of non-aggressive “standard opponents” (“intact” and “anosmic” group-housed males) produced similar behavioral changes in isolated OF1 male mice given several experiences of victory. Experimental groups confronted either intact or anosmic opponents every two days until they had completed four encounters. The behavioral changes were recorded using a detailed ethologically inspired analysis. These changes were clearly different depending on the opponent type. When intact opponents were used, experimental subjects increased the time spent in digging, non-social exploration, explore from a distance, and attack over encounters, but showed decreased time spen…
