    Political frameworks such as assimilation, accommodation and multiculturalism that have sought to address difference have failed to achieve political equality and inclusion for immigrants, driven primarily by the flawed understanding of culture and identity in multicultural states. Offering a brief critique of these models, this essay advocates the use of deliberative theory in citizenship education as instrumental to building capacities for inclusive citizenship and cultivating belonging and inclusion in diverse societies. Deliberative practice enables the reconceptualization of citizenship as performative, involving responsibilities for dialogic engagement. Such capacities and responsibilities are indispensable for a just political order in multicultural societies. © 2012 The Author(s).published_or_final_versio

    Heart Rate during Conflicts Predicts Post-Conflict Stress-Related Behavior in Greylag Geese

    Background: Social stressors are known to be among the most potent stressors in group-living animals. This is not only manifested in individual physiology (heart rate, glucocorticoids), but also in how individuals behave directly after a conflict. Certain ‘stress-related behaviors ’ such as autopreening, body shaking, scratching and vigilance have been suggested to indicate an individual’s emotional state. Such behaviors may also alleviate stress, but the behavioral context and physiological basis of those behaviors is still poorly understood. Methodology/Principal Findings: We recorded beat-to-beat heart rates (HR) of 22 greylag geese in response to agonistic encounters using fully implanted sensor-transmitter packages. Additionally, for 143 major events we analyzed the behavior shown by our focal animals in the first two minutes after an interaction. Our results show that the HR during encounters and characteristics of the interaction predicted the frequency and duration of behaviors shown after a conflict. Conclusions/Significance: To our knowledge this is the first study to quantify the physiological and behavioral responses to single agonistic encounters and to link this to post conflict behavior. Our results demonstrate that ‘stress-related behaviors’ are flexibly modulated by the characteristics of the preceding aggressive interaction and reflect the individual’s emotional strain, which is linked to autonomic arousal. We found no support for the stress-alleviating hypothesis, but we propose tha

    Post-conflict affiliation as conflict management in captive bottlenose dolphins (Tursiops truncatus)

    Post-conflict affiliation between former opponents or between one of the former opponents and bystanders might have the function of conflict management, which reduces the costs associated with aggressions. One of the suggested functions of post-conflict affiliation is decreased renewed aggressions directed from aggressors to victims. However, the effect of post-conflict affiliation on renewed aggressions by victims has not been investigated. We examined whether post-conflict affiliations decreased the number of renewed aggressions initiated by winners or losers in captive bottlenose dolphins. Both winners and losers initiated renewed aggressions. However, these aggressions decreased after post-conflict affiliation between former opponents, initiated by bystanders to winners, initiated by losers to bystanders, and initiated by bystanders to losers. Post-conflict affiliation between former opponents is suggested to function as reconciliation. Post-conflict affiliation initiated by losers to bystanders is suggested to function as the protection of losers. Post-conflict affiliations initiated by bystanders to one of former opponents are suggested to function as both appeasement and protection of the opponent who affiliates with bystanders

    Social Competitiveness and Plasticity of Neuroendocrine Function in Old Age: Influence of Neonatal Novelty Exposure and Maternal Care Reliability

    Early experience is known to have a profound impact on brain and behavioral function later in life. Relatively few studies, however, have examined whether the effects of early experience remain detectable in the aging animal. Here, we examined the effects of neonatal novelty exposure, an early stimulation procedure, on late senescent rats' ability to win in social competition. During the first 3 weeks of life, half of each litter received daily 3-min exposures to a novel environment while the other half stayed in the home cage. At 24 months of age, pairs of rats competed against each other for exclusive access to chocolate rewards. We found that novelty-exposed rats won more rewards than home-staying rats, indicating that early experience exerts a life-long effect on this aspect of social dominance. Furthermore, novelty-exposed but not home-staying rats exhibited habituation of corticosterone release across repeated days of social competition testing, suggesting that early experience permanently enhances plasticity of the stress response system. Finally, we report a surprising finding that across individual rat families, greater effects of neonatal novelty exposure on stress response plasticity were found among families whose dams provided more reliable, instead of a greater total quantity of, maternal care

    An Individual-Oriented Model on the Emergence of Support in Fights, Its Reciprocation and Exchange

    Complex social behaviour of primates has usually been attributed to the operation of complex cognition. Recently, models have shown that constraints imposed by the socio-spatial structuring of individuals in a group may result in an unexpectedly high number of patterns of complex social behaviour, resembling the dominance styles of egalitarian and despotic species of macaques and the differences between them. This includes affiliative patterns, such as reciprocation of grooming, grooming up the hierarchy, and reconciliation. In the present study, we show that the distribution of support in fights, which is the social behaviour that is potentially most sophisticated in terms of cognitive processes, may emerge in the same way. The model represents the spatial grouping of individuals and their social behaviour, such as their avoidance of risks during attacks, the self-reinforcing effects of winning and losing their fights, their tendency to join in fights of others that are close by (social facilitation), their tendency to groom when they are anxious, the reduction of their anxiety by grooming, and the increase of anxiety when involved in aggression. Further, we represent the difference in intensity of aggression apparent in egalitarian and despotic macaques. The model reproduces many aspects of support in fights, such as its different types, namely, conservative, bridging and revolutionary, patterns of choice of coalition partners attributed to triadic awareness, those of reciprocation of support and ‘spiteful acts’ and of exchange between support and grooming. This work is important because it suggests that behaviour that seems to result from sophisticated cognition may be a side-effect of spatial structure and dominance interactions and it shows that partial correlations fail to completely omit these effects of spatial structure. Further, the model is falsifiable, since it results in many patterns that can easily be tested in real primates by means of existing data

    Post-conflict behaviour of wild olive baboons. II. Stress and self-directed behaviour

    Previous studies indicate that the prosimate function of post-conflict affiliative interaction among primates is to reduce a victim's uncertainty about its opponent's future behaviour: the 'uncertainty reduction hypothesis' (AURELI &amp; VAN SCHAIK 1991; Ethology 89, 101-114). This study confirms and extends these results, demonstrating that they are neither a product of captivity nor specific to macaques: both victims and initiators of aggression in a large group of wild olive baboons exhibited elevated rates of self-directed behaviour (SDB) - scratching, autogrooming,, body-shaking and yawning - in a 10-min post-conflict period. During this period, they were more likely to receive further aggression. Reconciliation reduced both SDB and the incidence of further aggression. However, reconciliation only reduced SDB among individuals involved in conflicts in which both parries exchanged aggression. It is suggested that aggressors in unilateral conflicts were aroused rather tl;an uncertain and that their victims' lack of control over post-conflict interactions (which tended to be initiated by their opponents) prevented them from benefiting from reconciliation in the same fashion as longtailed macaque victims, which frequently initiated reconciliation.</p

    Post-conflict behaviour of wild olive baboons. I. Reconciliation, redirection and consolation.

    Observations of post-conflict interactions have provided important insights into primate social organization. In this study, the nature and determinants of post-conflict behaviour in a troop of wild olive baboons, Papio annbis, were investigated. Reconciliation was observed among all age-sex classes, occurring at a rate consistent with a relatively intolerant dominance style. Reconciliation was more frequent when one of the combatants carried a dependent infant but rarely followed conflicts associated with food. Neither the directionality nor the decidedness of conflicts affected conciliatory tendency. In contrast, opponents that were close kin or of similar rank reconciled more often. Olive baboons did not affiliate with non-combatants more frequently following aggression than in control periods, although affiliation with supporters and the close kin of opponents increased. Absence of consolation follows the observed cercopithecine pattern, consistent with the hypothesis that con solation requires an ability to empathize with the victim's distress. Initiation of post-conflict attacks on third parties was not elevated in victims of aggression. The rarity of redirection is attributed to spatial dispersion, the frequent bidirectionality of baboon aggression and regular male intervention in female conflicts, all of which appear to limit the availability of 'safe' targets.</p
