The Nuremberg Judgment on the leaders of Nazi Germany proclaimed ‘crimes against peace’ – the planning and waging of aggressive wars – to be ‘the supreme international crime’.  This charge was premised on two innovative ideas: that aggressive war was a crime, and that individuals could be held responsible for it. Although heralded as an historic milestone at the time, it turned out to be a transient legal anomaly.  At the Nuremberg Tribunal, the number of acquittals, coupled with the relative leniency of the sentences, indicated the judges’ unease about convicting on the basis of ‘crimes against peace’.  At the Tokyo Tribunal, some judges questioned the validity of the charge and filed dissents.  Legal observers, meanwhile, were outspoken in their criticisms, and argued that it was an ex post facto enactment, selectively applied. Aside from retroactivity and selectivity, the main difficulty arose from the internal contradictions within the charge itself, which rendered it unsustainable as a component of international law.  On jurisdiction, it enhanced the sovereignty of nations by protecting them against aggression, while simultaneously undermining sovereignty by subjecting leaders to international law.  On enforcement, while judicialising punishment after the event, it simultaneously de-legitimised both aggression and attempts to prevent it.  These weaknesses were confirmed by the failure of ‘crimes against peace’ to become part of customary international law. If the Rome Statute is amended to include ‘crime of aggression’ within the International Criminal Court’s operative remit, these latter problems are likely to occur.

This study attempted to determine the relationship between fantasy aggression and behavioral aggression, and whether fantasy aggression measured by the Thematic Apperception Test is related to behavioral aggression. Participant TAT protocols from psychology clinic files were scored for fantasy aggression, and these scores were correlated with self-reported presence or absence of behavioral aggression. The scoring system used was a blend of popular aggression scales used in the 1960s and newer theory. Other variables that were examined were story length and gender in relation to the measured amount of fantasy and behavioral aggression.

High prevalence rates and negative outcomes of peer-based aggression and victimization during early adolescence underscore the need to identify causes and consequences of these outcomes. Limited research has examined the impact of environmental and contextual factors, such as school climate, on peer aggression and victimization. Few studies have addressed relations between school climate and specific subtypes of physical and relational aggression and victimization. Although school climate has been assessed via interpersonal subsystems (i.e., student-student and student-teacher relationships), little research has incorporated the role of student awareness and reporting of violence and safety concerns. Further, studies are needed that consider the bi-directional relations between school climate and peer aggression and victimization over time. To address these limitations, the current longitudinal study examined associations between school climate (i.e., student-student and student-teacher relationships and awareness/reporting) and peer aggression and victimization over six months among a sample of 265 middle school students.

In eusocial insects, the ability to discriminate nest-mates from non-nest-mates is widespread and ensures that altruistic actions are directed towards kin and agonistic actions are directed towards non-relatives. Most tests of nest-mate recognition have focused on hymenopterans, and suggest that cooperation typically evolves in tandem with strong antagonism towards non-nest-mates. Here, we present evidence from a phylogenetically and behaviourally basal termite species that workers discriminate members of foreign colonies. However, contrary to our expectations, foreign intruders were the recipients of more rather than less cooperative behaviour and were not subjected to elevated aggression. We suggest that relationships between groups may be much more peaceable in basal termites compared with eusocial hymenoptera, owing to energetic and temporal constraints on colony growth, and the reduced incentive that totipotent workers (who may inherit breeding status) have to contribute to self-sacrificial intergroup conflict.

Cyberbullying is a category of bullying that occurs in the digital realm which affects our students at astonishing rates. Unlike traditional bullying, where displays of aggression may be evident to bystanders, the ramification of cyberbullying occurs through unconventional ways (e.g., text messaging; online weblogs; video sharing), which results in many cases being camouflaged by the advancement in technology. Nonetheless, the effects of this digital form of peer aggression can be as detrimental as face-to-face bullying. The characteristics of cyberbullying and its influences on adolescents and parents of adolescents were examined. The data accrued is based on an anonymous survey through one of the following methods: (a) paper-pencil survey for adolescent group with 37-question items on the adolescent questionnaire and (b) web-based survey for the parent group with 22-question items on the parent questionnaire. Each survey was systematically coded according to the participating group and assigned code numbers (i.e., 1 represents adolescent group and 2 represents parent group) was provided to ensure confidentiality of the study. Survey examined individual variables among the two target groups: (a) adolescents between 13 and 17 years of age and (b) parents of adolescents between 13 and 17 years of age. Specifically, individual variables examined include (a) demographics, (b) personal experiences, (c) vicarious experiences, and (d) preventative resources. A total of 137 participants (62 adolescents; 75 parents) responded to the survey. Results indicated that 90% of the participants from the adolescent group have reported to experience either as victims or as bystanders of cyberbullying. In addition, 70% of the victims have been cyberbullied 1 to 2 times within a month period and 50% of the victims did not know the perpetrator. Secondly, 89% of parent participants indicated to be knowledgeable about the issues relating to cyberbullying and 89% reported to have no knowledge if their child has or has not been a victim of cyberbullying. Furthermore, qualitative findings of personal perspectives toward cyberbullying from each participating group are discussed. A review of literature is provided and results and analysis of the survey are discussed as well as recommendations for future research.

Research has documented a tendency among youth to have biased interpretations of ambiguous information. For example, anxious youth are more likely to interpret ambiguous situations as negative or threatening (e.g., Cannon & Weems, 2010). Similarly, when interpreting social cues, aggressive youth exhibit hostile attribution biases more often than non-aggressive youth in response to ambiguous situations (e.g., Crick & Dodge, 1996). Research suggests that youth with anxiety and aggression exhibit differential physiological reactivity in response to threat. However, research has yet to examine the linkages amongst physiological reactivity to ambiguous situations, anxiety, and aggression in adolescents. The current study had several interrelated aims. Youths’ physiological responding (i.e., heart rate and skin conductance) to a series of animated vignettes depicting ambiguous social situations was examined. Anxiety, aggression, and hostile attributional bias (HAB) were also tested as predictors of differential physiological responding to the vignettes, as well as the interrelations between anxiety and HAB and aggression and HAB. Eighty youth completed a physiological assessment in which they viewed a series of hypothetical situational vignettes while their heart rate and skin conductance were measured. Participants also completed questionnaires measuring symptoms of anxiety, aggression, and HAB. Results indicated that there was differential physiological responding to the vignettes such that participants’ heart rates showed a pattern of deceleration followed by acceleration across time. Physiological responses were predicted by HAB such that those with high HAB had higher heart rates and exhibited more pronounced deceleration and acceleration across time than those with low HAB. There was support for anxiety as a significant predictor of responses among those participants with higher levels of HAB such that heart rates remained elevated with very little deceleration across time, suggesting a pattern of physiological hyperarousal and blunted reactivity. However, aggression did not predict differential physiological responding to the ambiguous vignettes, nor did HAB moderate the association between aggression and physiological responding. These findings add to the literature by contributing to knowledge about physiological responding to ambiguous situations and associations between this link with anxiety, aggression, and HAB.

The purpose of the proposed study is to consider why and under which conditions do supervisors engage in abusive behaviours towards their subordinates. To answer my first research question, why do supervisors engage in abusive supervision, I draw on victim precipitation (e.g., Sparks, Glenn, & Dodd, 1977) and conservation of resources (COR; Hobfoll, 1989) theories to argue that certain subordinate performance-related behaviours and characteristics threaten supervisor resources leading to abuse as a stress reaction. To answer my second research question, under which conditions do supervisors engage in abusive supervision, I draw on attribution theory (Heider, 1958; Weiner, 1986). I argue that supervisors abuse subordinates when they attribute responsibility, or blame subordinates for negative performance-related behaviours and characteristics, as a means of protecting or guarding against future resource loss. To answer my research questions, I developed measures for self- and other-perceived general mental ability (GMA) and blame attributions. I obtained data from 211 supervisor-subordinate dyads in Canada and the United States. Respondents were surveyed for information about their work behaviours, characteristics, and relationships. Using Hayes (2013) PROCESS macros, I found partial support for the proposed model and offer refinements to COR and victim precipitation theories. I found relationships between both self- and supervisor-reported subordinate behaviours and characteristics and abusive supervision, largely in the direction hypothesized. I also found supervisor-reported subordinate performance behaviours and perceived GMA to share a stronger relationship with subordinate reports of abusive supervision than subordinate reported behaviours and characteristics in many instances. / October 2016

The concept of level of aspiration bears directly on goal setting behavior; it is a convenient and important variable in understanding human motivation in a variety of situations. Thus it was the purpose of this study to investigate the relationships between levels of aspiration and the psychological needs of achievement, dominance, autonomy, change, and aggression.

Recently, with the development of new technology, researchers have focused on physiological predictors of aggressive behavior, specifically cortisol and alpha amylase. Gordis, Granger, Susman, and Trickett (2006) found the interaction between cortisol and alpha-amylase significantly predicted parent reports of aggression indicating that low levels of physiological reactivity was associated with higher levels of problem behavior. While this research has provided valuable information about aggressive behavior, a major limitation is the majority of research focuses on males, or has not examined gender differences explicitly. This study expanded on work by Gordis et al. (2006) and other researchers on the HPA axis and sympathetic nervous system responses and aggression by using a larger sample, focusing on female adolescents, examining both physical and relational aggression, and utilizing parent and adolescent reports of aggressive behavior. Based on prior literature, I expected that lower levels of salivary cortisol taken at the beginning of the interview and the beginning of the stress task would be associated with higher levels of physical and relational aggression in girls. I also hypothesized that lower levels of cortisol and α-amylase reactivity will be associated with higher levels of physical and relational aggression. Finally, I hypothesized that lower levels of cortisol reactivity coupled with higher levels of α-amylase reactivity will be associated with lower levels of aggressive behavior. Participants in the current study live in moderate- to high-violence areas in Richmond, VA. Participants were 146 adolescent females who were enrolled in a larger longitudinal study on coping with exposure to violence. Most of the adolescents were African-American (91.1%) with a mean age of 13.9 years old (range from 11-17). The changes in physiological responses were monitored during the interview process which included the administration of the Social Competence Interview (SCI). Aggression was measured using the Child Behavior Checklist and Problem Behavior Frequency Scales. In the analyses, I controlled for pubertal status, medication usage, race, and time of day which are all factors that can influence the level of cortisol and alpha-amylase. Results indicated that higher levels of basal cortisol were associated with higher levels of aggressive behavior. In contrast to previous research and prediction, results indicated that symmetry in α-amylase and cortisol predicted lower levels of self-reported physical aggression in girls. Asymmetry in the two systems was associated with higher levels of self-reported physical aggression. These results contribute to the mixed results on female physiological responses and aggression. It also provides support for symmetry in cortisol and α-amylase as a predictor of lower levels of aggressive behavior. Studying a child’s physiological reactions to stress can give insight into behavior regulation, help identify adolescents for prevention/intervention, and serve as markers of treatment progress. These data suggest that physiological associations with aggression may not be the same for males and females, or for youth living in extremely stressful circumstances. Further research is needed to replicate these finding, and specifically to compare these patterns of associations across gender.

High prevalence and the negative legal, health, and psychological consequences of adolescent dating aggression underscore the need to identify risk and protective processes associated with this type of aggression. Studying dating aggression in early adolescence is important, as this is the developmental time frame when most youth are establishing attitudes, beliefs, and norms for dating behaviors. The current study investigated longitudinal associations between perceived parental and peer support for violent and nonviolent responses to conflict and dating aggression perpetration among middle school students. Participants included 1,399 adolescents (52% female) in the sixth (n = 466), seventh (n = 467), and eighth (n = 466) grades. Results showed that peer support for nonviolent responses predicted lower frequencies of subsequent dating aggression among sixth graders, and perceived parental support for nonviolent responses resulted in decreased frequencies of dating aggression in the seventh and eighth grades. Peer support for violent responses predicted increased dating aggression in the seventh grade, and perceived parental support for violent responses led to higher frequencies of dating aggression in the eighth grade. Additionally, dating aggression predicted changes in adolescent perceptions of parental and peer support for violent and nonviolent responses. No sex differences were found in these models. Lastly, moderation analyses identified two significant interactions. These interactions illustrated that different combinations of parental and peer support for violent and nonviolent responses affected dating aggression perpetration, highlighting the importance of examining mixed messages and combinations of messages from parents and peers. Overall, the findings from the current study indicated that adolescent perceptions of parental and peer support for violent and nonviolent responses to conflict are important risk and protective processes, respectively, that are longitudinally associated with dating aggression. These findings can inform dating violence prevention programs, and stress the importance of adolescent, parental, and peer involvement in these programs.
