Kinds of Fighting Terms modified by Fighting Selected AbstractsFighting over the Forests: Environmental Conflict and Decision-making Capacity in Forest Planning ProcessesGEOGRAPHICAL RESEARCH, Issue 3 2003Jean Hillier Abstract This paper tells a story of environmental conflict and the attempted political resolution of issues of planning for native forests in Western Australia. It refers to the Western Australian Regional Forest Agreement and Draft Forest Management Plan processes to demonstrate how a range of actors utilise vari-ous discourses and network relations in attempts to influence governmental decision-making capacity. Adapting elements of a model of capacity-building for environmental decision-making, the paper indicates how traditional exclusionary decision networks serve to inhibit decision capacity, whilst more inclusive processes may be more likely to cope with challenges of reconciling multiple values and decision-making for managing the forests in the interests of society as a whole. [source] The Spectacle of Men FightingIDS BULLETIN, Issue 2 2000Alan Greig Summaries The meaning of male violence should be a central concern of Gender and Development (GAD) discourse and practice. Explanations of the nature, and limits, of men's responsibility for such violence increasingly centre on their socialisation into a masculine identity. By counter-posing the ,individual' and the ,social', attention becomes fixed on identity as the surface that connects these two realities on which is inscribed the masculinity of men. The task of responding to the spectacle of men fighting then appears to be one of re-inscribing a new non-violent masculine identity. This paper argues that GAD practitioners should be wary of this kind of politics of identity. Focusing on identification as relation, rather than identity as boundary, clarifies the violent politics of difference at the heart of masculinity. Addressing violence means approaching a new politics of difference. This is a politics of alliance and coalition, a transgressing of sectoral and institutional boundaries in recognition of the common bases of oppression and their plural manifestations in women's and men's lives. GAD can address the politics of identification(s) by approaching questions of responsibility for and complicity in male violence as personal-communal issues. Depending on what they choose to fight for, the spectacle of men fighting can be a sight, and site, of real political potency. [source] Recovering from recurrent mental health problems: Giving up and fighting to get betterINTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 1 2010Yulia Kartalova-O'Doherty ABSTRACT The purpose of this paper is to present selected findings of a grounded theory study that aims to explore individual processes and desired outcomes of recovery from recurrent health problems in order to build up a theoretical framework of recovery in an Irish context. Volunteers included mental health service users or participants of peer support groups who have experienced recurrent mental health problems for two or more years, consider themselves in improvement, and are willing to participate in individual interviews. The current paper is based on the analysis of 15 audiorecorded and transcribed interviews. We identified two open codes of ,giving up' and ,fighting to get better'. Giving up was associated with accepting a passive identity of a patient with a chronic mental illness and a lack of intrinsic motivation to get better. Fighting had both positive (fighting for) and negative (fighting against) dimensions, as well as internal and external ones. The fight for recovery entailed substantial and sometimes risky effort. Starting such a fight required strong, self-sustained motivation. Service providers might need to discuss internal and external motivators of fighting for recovery with service users, with a view to including such motivators in the care plans. [source] Estimation of the probability of fighting in fallow deer (Dama dama) during the rutAGGRESSIVE BEHAVIOR, Issue 1 2007k Barto Abstract Fighting between males is a frequent component of the rutting behavior of Cervidae. Frequent conflicts are exhausting; fighting may be risky and can lead to serious injuries or even death. We focused on the process of assessment of the opponent's fighting ability and escalation of the combat, estimating the probability of fighting based on the encounter components such as groaning and parallel walk. In this study, we observed the agonistic behavior of fallow deer bucks (Dama dama) during the rut over four seasons. During this time, we recorded 205 encounters between bucks. Non-contact display, which allows contestants to assess their opponents fighting ability, occurred in 83% of the encounters. The highest predicted probability of a fight was found when both of the males vocalized and turned into the parallel walk. The chance of a clear outcome decreased when the males were fighting in comparison to when they did not fight. The initiator of the competitive encounter won 41% of the cases, while the attacked buck won 23% of the encounters. If the contestants avoided fighting, however, the initiator won 78% of encounters. Therefore, the initiator was more successful when no fight occurred compared to when the encounters escalated into fighting. In most cases where ritualized behavior occurred, one of the opponents left after vocalization or parallel walk occurred. Thus, vocalization and parallel walk increased the probability for a clear outcome. The probability of a fight was lowest in situations where the males displayed asymmetric behavior. Increased symmetry of the contestants' behavior was strongly correlated with a higher probability of a fight. Thus, these results indicate that fallow deer bucks use efficient tactic during the rut, which, in turn, minimizes the chance of injury while fighting during the breeding season. Aggr.

[source] Fighting like a girl fighting like a guy: Gender identity, ideology, and girls at early adolescenceNEW DIRECTIONS FOR CHILD & ADOLESCENT DEVELOPMENT, Issue 120 2008Lyn Mikel Brown In this chapter we explore the phenomenon of "girls fighting like guys" by listening to adolescent girls' justification for physical fighting with other girls. We argue that physical girlfighting is a particular kind of gendered performance,a performance of identity that expresses, at least in part, an answer to the question, "Who am I?",that both perpetuates and challenges the usual notions of masculinity and femininity and the differential power associated with these discourses. We present a sociocultural approach to identity that we believe not only holds promise for helping us to understand girl-fighting behavior but also highlights the clear interrelationship between social identity and personal identity. We conclude by highlighting several implications of this analysis for those who work with girls (and boys) in educational and clinical settings. © Wiley Periodicals, Inc.

Peterson In this archival study, themes of authoritarianism (Adorno, Frenkel-Brunswik, Levinson, & Sanford, 1950) were content coded in American comic books. Comic books produced during years of relatively high social and economic threat (1978,82 and 1991,92) contained more aggressive imagery, more conventional themes, less intraception, and fewer spoken lines by women characters relative to comic books produced during years of relatively low threat (1983,90). Unexpectedly, speaking roles for characters of color did not differ due to the influence of threat. Discussion focused on the theoretical relationship between threat and manifestations of authoritarianism at the societal and individual levels.

Silver This article reviews the development of the Sieve Model, conceived from dissatisfaction with adversarial processes that encouraged endless destructive fighting and depletion of financial and emotional family resources. Adversarial approaches discourage constructive problem solving and cooperation and are very hard on children. Rather than a piecemeal approach toward divorce, a systemic model was conceived. The Sieve Model is being implemented in the 20th Judicial Circuit of the State of Florida through differentiated case management, after a study revealed that protracted cases primarily involved disputes over children. Families are invited to use pertinent elements in an individualized fashion. Family law professionals are challenged to develop other solution-based efforts akin to mediation to assist families of divorce. The Sieve Model encourages participants to practice solving problems rather than creating them, decreasing divorce brutality and postjudgment conflicts.

The WHO guidelines were used to classify the traumatic injuries. A total of 590 children were involved, 810 teeth being affected. Children aged 7,14 years made up 88% of the cohort. The male:female ratio was 58:42. The permanent:primary ratio for the affected teeth was 90:10. The teeth most commonly affected were the maxillary central incisors. In 70% of the cases, only one tooth was traumatised. The incidence of dental trauma peaked at 10 years of age. The most common injury type observed was enamel-dentin crown fracture. The decreasing sequence of frequency of etiological factors was playing, sports, falls, cycling, road accidents and fighting. Of the accidents, 65% occurred at school or at home. Seventy seven per cent of the patients presented for medical care in the first 3 days after the accident. [source] The influence of natural variations in maternal care on play fighting in the ratDEVELOPMENTAL PSYCHOBIOLOGY, Issue 8 2008Carine I. Parent Abstract Naturally occurring variations in maternal care in the rat influence the sensitivity of offspring to stress in adulthood. The offspring of mothers that show lower levels of pup licking/grooming (i.e., low-LG mothers) demonstrate enhanced responses to stress and increased anxiety compared to those of high-LG mothers. Low-LG offspring are also more sensitive to the influence of environmental enrichment than high-LG offspring. This study examined play fighting in the juvenile offspring of high-LG and low-LG dams in a multiple-play partners housing environment. Male offspring from low-LG dams demonstrated a significantly higher frequency of pouncing, pinning and aggressive social grooming than did high-LG males and high-LG and low-LG females. Consistent with earlier reports, male pups engaged in more play fighting than did females and maternal care was associated with differences in play fighting but only in males. Lower levels of stimulation in the form of LG from the dam during perinatal development may thus increase sensitivity for the stimulating effects of play behavior in periadolescence, in part explaining the increased solicitation of play fighting through increased pouncing in the male offspring of the low-LG mothers. These findings identify a possible influence of variations in maternal care on play fighting and suggest that maternal care in the perinatal period influence social interactions during periadolescence. © 2008 Wiley Periodicals, Inc.

Field Abstract The frequency of playful attack and the style of playful defense, are modifiable by gonadal steroids and change after puberty in male and female rats. The present study examined the play behavior exhibited by testicular feminized mutation (tfm) -affected males, who are insensitive to androgens but can bind estrogens aromatized from androgens, to determine the relative contributions of androgens and estrogens to the age-related changes in play behavior. tfm males did not exhibit a decrease in playful attack with age and were more likely to maintain the use of complete rotations, a juvenile form of playful defense, into adulthood. tfm males did however, show age related changes in the use of partial rotations and upright postures, two other forms of playful defense, that were similar to normal males. These data suggest that the development of play fighting and defense in males is dependent on both androgen- and estrogen-receptor-mediated effects. © 2006 Wiley Periodicals, Inc.

[source] The development of "roughness" in the play fighting of rats: A Laban Movement Analysis perspectiveDEVELOPMENTAL PSYCHOBIOLOGY, Issue 1 2003Afra Foroud Abstract With increasing age, rats, when play fighting, become rougher. In part, this change can be accounted for by the increasing likelihood of using adult-typical fighting tactics. However, even when using the same tactics, adults appear rougher than juveniles in their play. In this study, videotaped sequences of play fighting in rats from the juvenile (30 days) to the post-pubertal (70 days) period were analyzed using Laban Movement Analysis (LMA). Movement qualities called Effort Factors in LMA captured the character of some of this change. Juveniles tended to use Indulging Efforts, whereas older rats tended to use Condensing Efforts. The latter are related to performing movements that are more controlled. This greater level of control was also evident in the way older rats maintained postural support during play fights. When standing over supine partners, juveniles are more likely to stand on the partner with all four paws, reducing their postural stability, and hence ability to control their partner's movements. Older rats are more likely to place their hind paws on the ground, thus providing a firmer anchor for movements with their upper bodies and forepaws. These age-related changes in behavior were found for both males and females. The findings lend support to a growing body of evidence that play fighting in the juvenile phase of rats is not just a more frequently occurring version of that present in adults, but rather, has unique organizational properties. © 2003 Wiley Periodicals, Inc.

Karppinen Abstract,,, In this paper, we describe a method employing motion-sensing radio transmitters for recording and identifying behavioural patterns and activity of Atlantic salmon spawning under natural conditions. Simultaneous video monitoring verified recorded activity patterns originating from behaviours such as fighting, nest digging and quivering. The method described here enables more accurate determination of the timing and location of spawning compared to conventional location tracking. Motion-sensing transmitters can also be applied to monitor other species and types of behaviour, and therefore the use and development of such methods deserves further attention in behavioural studies. [source] Dominance, Status Signals and Coloration in Male Mandrills (Mandrillus sphinx)ETHOLOGY, Issue 1 2005Joanna M. Setchell Where individuals contest access to a resource, escalated physical fighting presents a risk to all involved. The requirement for mechanisms of conflict management has led to the evolution of a variety of decision rules and signals that act to reduce the frequency of aggression during competitive encounters. We examined strategies of conflict management in male mandrills (Mandrillus sphinx) living in two semi-free-ranging groups in Gabon. Adult male mandrills are large (31 kg), with long canines, making the costs of conflict potentially very high. We found that males formed dominance hierarchies, but that male,male relationships were characterized by avoidance, appeasement and ignoring. Fights were rare, but could result in death. Examination of the relationship between dominance and signaling showed that males use facial and gestural signals to communicate dominance and subordinance, avoiding escalated conflict. Male mandrills also possess rank-dependent red coloration on the face, rump and genitalia, and we examined the hypothesis that this coloration acts as a ,badge of status', communicating male fighting ability to other males. If this is the case, then similarity in color should lead to higher dyadic rates of aggression, while males that differ markedly should resolve encounters quickly, with the paler individual retreating. Indeed, appeasement (the ,grin' display), threats, fights and tense ,stand-off' encounters were significantly more frequent between similarly colored males, while clear submission was more frequent where color differences were large. We conclude that male mandrills employ both formal behavioral indicators of dominance and of subordination, and may also use relative brightness of red coloration to facilitate the assessment of individual differences in fighting ability, thereby regulating the degree of costly, escalated conflict between well-armed males. [source] Male Competition over Access to Females in a Spider with Last-Male Sperm PrecedenceETHOLOGY, Issue 5 2003Daniela Schaefer Agonistic behaviour between male cellar spiders (Pholcus phalangioides) was investigated to test whether (1) size difference determines which male achieves access to the female, (2) males are able to monopolize access to the female until egg laying and whether (3) female resource value increases before egg laying because of last-male sperm precedence. We further investigated whether (4) there is variation in time and energy spent on courtship and copulation depending on the degree of sperm competition, i.e. with or without rival present. In three experimental settings we introduced two males of either different or similar sizes, or a single male to a female. The mating units were constantly video-observed until the females produced their first egg sac. Experience, ownership and female resource value in terms of body size was controlled. Our results show that larger males achieve almost exclusive access to females. Size symmetrical settings resulted in increased fighting activity and duration but dominance did not influence mating success. If copulations were disturbed by the rival male, copulations were terminated earlier in symmetrical settings compared with asymmetrical settings. In 94.8% of trials only one copulation took place, suggesting that the copulating male successfully monopolized access to the female. Males confronted with a rival copulated longer but courted significantly shorter than lone males. Although the last male to copulate sires 88% of the offspring in P. phalangioides, neither fighting nor courtship activity increased before the female laid a batch of eggs. This suggests that males have no indication of the timing of oviposition. [source] Does Lateral Presentation of the Palmate Antlers During Fights by Fallow Deer (Dama dama L.) Signify Dominance or Submission?ETHOLOGY, Issue 5 2002Dómhnall J. Jennings A central aim of the study of animal communication is to identify the mode and content of information transferred between individuals. The lateral presentation of the antler palm between male fallow deer has been described as either a signal of individual quality or an attempt to avoid fighting. In the first case two phenotypic features have been proposed by which transmission of individual quality may be facilitated. These are antler size and antler symmetry. The alternative hypothesis proposes that the lateral presentation of antlers occurs as a consequence of averting a threatening posture and may signify a reluctance to fight. We examined whether mature fallow deer use lateral palm presentation as a display during fights to indicate antler size and symmetry. We found no relationship between presentation rate of the antler and antler size and symmetry. Furthermore, males did not preferentially present their larger antler to their opponent. We also investigated whether the rate at which males presented antlers laterally during a fight was related to their ability to win the fight. Our results show that the male who performed more presentations during a fight was more likely to lose it. There were behavioural differences in the way in which a bout of presentation ended; subsequent losers tended to turn their body away from their opponent and subsequent winners tended to lower their antlers to an opponent which we interpret as an invitation to continue fighting. We conclude that the lateral palm presentation serves to de-escalate fighting between mature fallow deer. It is not a mechanism by which to communicate individual quality but rather an indication that a male is less committed to continuing investment in the current contest. [source] Physiological constraints on contest behaviourFUNCTIONAL ECOLOGY, Issue 4 2007M. BRIFFA Summary 1Contests may involve injurious fighting, other types of direct physical aggression and communication. They occur over ownership access to mates and other resources that may increase an individual's attractiveness and its chance of survival. Traits that enhance resource holding potential may be the result of sexual selection, natural selection or a combination of both. 2Agonistic behaviours are expected to be demanding to perform and costly in terms of changes in physiological state. The ability to meet the physiological costs may determine contest outcomes and constrain the intensity of agonistic activities. 3The energetic costs have been investigated in a broad range of taxa using a variety of techniques. They include the mobilization of energy reserves, but a key cost in several taxa appears to be limited anaerobic capacity and subsequent accumulation of lactic acid. Androgens, stress hormones and neurohormones have also been shown to constrain fighting behaviour. However, due to key differences in the endocrine systems of vertebrates and invertebrates, the effects of hormones are far less consistent across taxa than in the case of metabolites. 4Physiological constraints on fighting may vary according to their importance relative to circumstantial costs, the time-scale over which they exert their effects, their effects on different roles and their causal links with behaviour. Incorporating these factors into theoretical studies of contest behaviour may give further insights of how the costs of fighting influence agonistic behaviour. [source] Dissecting innate immunity by germline mutagenesisIMMUNOLOGY, Issue 4 2008Sophie Rutschmann Summary The innate arm of our immune system is the first line of defence against infections. In addition, it is believed to drive adaptive immune responses, which help fight pathogens and provide long-term memory. As such, the innate immune system is instrumental for protection against pathogens that would otherwise destroy their host. Although our understanding of the innate immune components involved in pathogen sensing and fighting is improving, it is still limited. This is particularly exemplified by increased documentation of innate immune deficiencies in humans that often result in high and recurrent susceptibility to infections or even death, without the genetic cause being evident. To provide further insight into the mechanisms by which pathogen sensing and eradication occur, several strategies can be used. The current review focuses on the forward genetic approaches that have been used to dissect innate immunity in the fruit fly and the mouse. For both animal models, forward genetics has been instrumental in the deciphering of innate immunity and has greatly improved our understanding of how we respond to invading pathogens. [source] Understanding the Helmand campaign: British military operations in AfghanistanINTERNATIONAL AFFAIRS, Issue 2 2010ANTHONY KING British forces are now engaged in a major operation in southern Afghanistan, the outcome of which is likely to be strategically decisive,especially for the configuration and status of Britain's land forces. Although progress seems to have been made, there has been much criticism of the campaign. Through an analysis of the three-year Helmand mission (Operation Herrick), this article explores whether, for all the improvements in the campaign in terms of resources and numbers of troops, the basic structure of the campaign established in 2006 has endured. Instead of focusing on an ,ink-spot' from which to expand, British forces have tended to operate from dispersed forward operating bases from which they have insufficient combat power to dominate terrain and secure the population. They are consequently engaged in a seemingly endless round of high-intensity tactical battles which are normally successful in themselves but do not contribute to the overarching security of the province. The analysis explores the way in which this distinctive campaign lay-down,the preference for dispersal and high-intensity fighting,may be a reflection of British military culture and its military doctrine. By highlighting potential unacknowledged aspects of the British military profession, the article aims to contribute to debates about the development of the armed forces.

I demonstrate how gendered discourses are used in this and other conflict situations to reinforce mutual hostilities. I suggest that men's association with war,fighting and national security serves to reinforce their legitimacy in world politics while it acts to create barriers for women. Using the framework of a post,9/11 world, I offer some alternative models of masculinity and some cultural representations less dependent on the subordination of women. Often in times of conflict women are seen only as victims. I outline some ways in which the women of Afghanistan are fighting against gender oppression and I conclude with some thoughts on their future prospects. [source] Foreign Policy Gaps between Citizens and LeadersINTERNATIONAL STUDIES QUARTERLY, Issue 3 2000Benjamin I. Page Persistent gaps between the policy preferences of leaders and those of citizens are problematic from the point of view of democratic theory. Examination of the foreign policy preferences of samples of citizens and leaders from seven Chicago Council on Foreign Relations (CCFR) surveys between 1974 and 1998 reveals many differences of 30, 40, and even 50 percentage points. Often a majority of the public has disagreed with a majority of leaders. Some of the same gaps have persisted over the full 24-year period of these surveys. The pattern of gaps is considerably more complicated than a simple difference in degree of commitment to internationalism. Citizens have generally put a higher priority than leaders on expanding domestic programs like Social Security, crime fighting, and health care, and have been more eager to cut foreign economic aid. But there have not been substantial gaps with respect to defense spending or military aid. More members of the public than leaders emphasize foreign policy goals related to protecting Americans' jobs and ensuring Americans' health and physical security (e.g., from terrorism, drugs, and epidemic diseases). Citizens have been more reluctant than leaders to use U.S. troops in most circumstances, but the opposite is true of situations involving Latin America. Citizens have been more willing to bomb than to commit troops, though not indiscriminately so, and many more citizens than leaders oppose selling weapons abroad. Fewer members of the public than leaders have favored most kinds of cooperative relationships with adversary countries. But more members of the public than leaders generally support the United Nations, and more favor multilateralism in general. About the same number of citizens as leaders have supported NATO. Some of these gaps may reflect lower levels of attention to foreign affairs and lower levels of information among the public than among leaders, but many of the gaps may instead reflect different values and interests. In cases where the public is ill-informed, persistent gaps suggest a failure of leaders to educate and persuade. Where public opinion is well-informed and deliberative, democratic theory would seem to call for responsiveness by policymakers. [source] The systematic approach to flooding problems,IRRIGATION AND DRAINAGE, Issue S1 2006J. (Hans) van Duivendijk maîtrise des crues; mesures non-structurelles; gestion des inondations Abstract Since 1987 one of the working groups of the International Commission on Irrigation and Drainage (ICID) has, inter alia, been preparing two manuals concerning approaches to flooding problems. The Manual on Non-Structural Approaches to Flood Management was issued in 1999 while the Manual on the Planning of Structural Approaches to Flood Management has been issued recently (2005). In this paper a broad outline of both manuals is presented. The first manual describes in detail the various planning and response measures in flood management, which are known as non-structural measures. The latter are measures which alter the exposure of life and property to flooding but do not change the flood(ing) phenomenon as such. The said planning and response measures comprise such actions as floodplain land use management, flood forecasting and warning, flood fighting, flood proofing, etc. It is explained that such measures are sometimes the only ones feasible in the prevailing circumstances and that, moreover, non-structural measures should always be added to the so-called structural measures if the latter are considered feasible (i.e. feasible from a technical, economic, socio-economic and ecological point of view). In the second manual a methodology is presented for the planning of structural measures. This type of measure alters the physical characteristics of the floods and in this connection one must think of the operation of flood storage reservoirs, upstream catchment management, modification to river channels, construction of levees, special flood diversion channels (bypasses) and operation of hydraulics works. The idea behind this methodology is that it is difficult for planners and decision makers to select the appropriate flood protection system for a given situation including a range of possible floods if the problem is not approached in a systematic manner. Copyright © 2006 John Wiley & Sons, Ltd. Depuis 1987 un des groupes de travail de la CIID prépare, entre autres, deux manuels sur la manière d'approcher les problèmes d'inondation. Le ,Manuel d'approche non-structurelle de la gestion des crues' a été publié en 1999, tandis que le ,Manuel de la planification de l'approche structurelle de la gestion des crues' a été publié plus récemment (2005). Le présent article présente une vue d'ensemble de ces deux manuels. Le premier manuel donne une description détaillée des différentes mesures de préparation et de réponse à la gestion des crues, connues comme étant non-structurelles. Ces mesures changent l'exposition de la vie et des propriétés aux inondations mais ne modifient pas le phénomène proprement dit des crues et des inondations. Elles comprennent des actions telles que la gestion de l'espace dans les plaines d'inondations, les prévisions et alertes, la lutte contre les crues, la protection contre les inondations, etc. On y explique que ces mesures sont parfois les seules faisables dans les circonstances données et que, en outre, des mesures non-structurelles devraient toujours être ajoutées aux mesures dites structurelles si ces dernières sont considérées comme faisables (c'est-à-dire faisables d'un point de vue technique, économique, socio-économique et écologique). Dans le second manuel une méthodologie est présentée pour la planification des mesures structurelles. Ce type de mesures modifie les caractéristiques physiques des crues, comme par exemple réservoirs d'écrétage de crue, gestion des hauts bassins, modification des lits des fleuves, construction de digues, canaux spéciaux de déviation des crues (courts circuits) et fonctionnement d'ouvrages hydrauliques. L'idée qui est derrière cette méthodologie est qu'il est difficile aux planificateurs et aux décideurs de choisir le système de protection contre les crues correspondant exactement à une situation comprenant une large gamme d'inondations possibles si le problème n'est pas approché de manière systématique.

MarcusArticle first published online: 9 DEC 200 Abstract Theories of emerging adulthood, the evolutionary perspective, and the presence of turning points in the lives of 19,25-year olds were examined in relation to serious perpetrated violence for a cross-sectional sample of men and women (n=14,098) from the National Longitudinal Study of Adolescent Health (Add Health), Wave III. Perpetrated, self-reported violence included armed robbery, gang fighting, using a weapon in a fight, pulling a knife or gun on someone, or shooting or stabbing someone. Results showed that 11.3% of emergent adults had perpetrated at least one of these behaviors in the past year. Hierarchical logistic regression analysis partially supported the three theories for both men and women, beyond the contribution of violence in adolescence. The presence of Wave III violence was more likely given the unique contributions of unmarried status and economic risk. Moreover, and consistent with the theory of emerging adulthood, both sensation seeking and depression declined with age and contributed to the acknowledgement of Wave III violence, beyond the contribution of controls for Wave I violence (6 years earlier), demographics, age, gender, unmarried status, and economic risk. Findings of age-related declines and gender differences in prevalence rates were consistent with previous research on nationally representative samples, and with the predictions of the three theories.

[source] Estimation of the probability of fighting in fallow deer (Dama dama) during the rutAGGRESSIVE BEHAVIOR, Issue 1 2007k Barto Abstract Fighting between males is a frequent component of the rutting behavior of Cervidae. Frequent conflicts are exhausting; fighting may be risky and can lead to serious injuries or even death. We focused on the process of assessment of the opponent's fighting ability and escalation of the combat, estimating the probability of fighting based on the encounter components such as groaning and parallel walk. In this study, we observed the agonistic behavior of fallow deer bucks (Dama dama) during the rut over four seasons. During this time, we recorded 205 encounters between bucks. Non-contact display, which allows contestants to assess their opponents fighting ability, occurred in 83% of the encounters. The highest predicted probability of a fight was found when both of the males vocalized and turned into the parallel walk. The chance of a clear outcome decreased when the males were fighting in comparison to when they did not fight. The initiator of the competitive encounter won 41% of the cases, while the attacked buck won 23% of the encounters. If the contestants avoided fighting, however, the initiator won 78% of encounters. Therefore, the initiator was more successful when no fight occurred compared to when the encounters escalated into fighting. In most cases where ritualized behavior occurred, one of the opponents left after vocalization or parallel walk occurred. Thus, vocalization and parallel walk increased the probability for a clear outcome. The probability of a fight was lowest in situations where the males displayed asymmetric behavior. Increased symmetry of the contestants' behavior was strongly correlated with a higher probability of a fight. Thus, these results indicate that fallow deer bucks use efficient tactic during the rut, which, in turn, minimizes the chance of injury while fighting during the breeding season. Aggr.

[source] Glucocorticoids and the Development of Agonistic Behaviour during Puberty in Male Golden HamstersJOURNAL OF NEUROENDOCRINOLOGY, Issue 12 2005J. C. Wommack Abstract During puberty, the agonistic behaviour of male golden hamsters undergoes a transition from play fighting to adult aggression. Repeated exposure to social stress early in puberty accelerates this transition. The present study investigated the possible role of glucocorticoids on the maturation of agonistic behaviour. First, we compared serum cortisol levels following a 20-min restraint stress during early puberty, mid-puberty or adulthood. Across puberty, animals exhibited a two-fold increase in post-restraint cortisol levels. We also compared corticotrophin-releasing hormone (CRH) immunoreactive fibres projecting to the median eminence between animals in early puberty and adulthood. The CRH fibre density was two-fold greater in adults compared to juveniles. Furthermore, we investigated the effects of stress hormones on the maturation of agonistic behaviour. Male hamsters were injected daily with dexamethasone, a corticosteroid receptor type II agonist (0, 10 or 40 µg/100 g), early in puberty from postnatal day 31 (P-31) to P-36. When paired with a smaller and younger intruder on P-37, attack frequency did not differ between groups. However, dexamethasone-treated animals showed a dose-dependent decrease in the percentage of play-fighting attacks and an increase in the percentage of adult attacks. In summary, puberty can be described as a period of increasing hypothalamic-pituitary-adrenal activity in male golden hamsters. Moreover, increasing glucocorticoid levels influence the maturation of agonistic behaviour. These data shed new light on the neuroendocrine mechanisms that regulate the maturation of social behaviours during puberty. [source] Ethanol-Induced Social Facilitation in Adolescent Rats: Role of Endogenous Activity at Mu Opioid ReceptorsALCOHOLISM, Issue 6 2009Elena I. Varlinskaya Background:, Ethanol consumption is considerably elevated during adolescence. Attractiveness of alcohol for humans during the adolescent developmental period is based, in part, on its ability to induce social facilitation,a facilitation of social interactions not only evident in human adolescents but also in adolescent rats. Endogenous opioid systems are among the multiple neural systems implicated in the behavioral and reinforcing effects of ethanol and may play a substantial role in modulating stimulatory effects of low doses of ethanol on social behavior during adolescence. This possibility was explored in the present study through the use of an animal model of peer-directed social behavior. Methods:, Sprague,Dawley rats were challenged early in adolescence with saline or ethanol intraperitoneally (i.p.), placed into an individual holding cage for 30 minutes, and then tested in a familiar situation with a nonmanipulated partner of the same age and sex. In Experiment 1, each test subject was injected subcutaneously with one of the three doses of a nonselective opioid antagonist naloxone (0, 0.05, and 0.1 mg/kg), 5 minutes prior to the social interaction test and 25 minutes following challenge with saline or ethanol (0.5 g/kg), whereas in Experiment 2 animals were challenged with one of the six doses of ethanol (0, 0.25, 0.5, 0.75, 1.0, and 1.25 g/kg) prior to injection of either saline or naloxone (0.05 mg/kg). In Experiment 3, animals were pretreated i.p. with the selective ,-opioid antagonist CTOP (0, 0.01, 0.025, 0.05, and 0.1 mg/kg) 30 minutes prior to challenge with saline or ethanol (0.5 g/kg). Results:, Low doses of ethanol (0.5 and 0.75 g/kg) produced social facilitation, as indexed by significant increases in play fighting and social investigation. Both doses of naloxone and the three highest doses of CTOP blocked the stimulatory effects of ethanol on play fighting but not on social investigation. These effects were not associated with alterations in ethanol pharmacokinetic properties or with shifts in the biphasic ethanol dose,response curve. Conclusions:, Ethanol-induced facilitation of social play behavior seen in adolescent animals is mediated in part through ethanol-induced release of endogenous ligands for the ,-opioid receptor or an ethanol-associated enhancement of sensitivity of these receptors for their endogenous ligands. [source] Sexual dimorphism of body size and shell shape in European tortoisesJOURNAL OF ZOOLOGY, Issue 4 2003Ronald E. Willemsen Adult body size and shape were examined in almost 1400 individuals of the tortoises Testudo graeca, T. hermanni and T. marginata from Greece. The size at maturity was greater in females than in males in all three species. Maximum and mean adult sizes were also greater in females than in males in T. graeca and T. hermanni. Males grew to a larger size than females in T. marginata, and mean adult size was similar in the sexes in this species. Sexual dimorphism of shape (adjusted for size covariate) was shown in most of the characters examined, and the degree of this dimorphism differed significantly among the three species. Differences were related to their contrasting courtship behaviours: horizontal head movements and severe biting in T. marginata, vertical head bobs and carapace butting in T. graeca, and mounting and tail thrusting in T. hermanni. There was no difference in the frequency of observations of courtship or fighting among the three species, but courtship was about 10 times more common than combat in males. All species showed greatest courtship activity in autumn; copulation was rarely observed in T. hermanni (only 0.36% of courting males) and not seen in the other species in the field. Observations made throughout the activity season indicated that feeding was equally common in males and females in all three species. Differences in shape were more likely to be the result of sexual selection than of natural selection for fecundity. Detailed predictions are made for sexual dimorphism of other characters in these species. [source] Fighting like a girl fighting like a guy: Gender identity, ideology, and girls at early adolescenceNEW DIRECTIONS FOR CHILD & ADOLESCENT DEVELOPMENT, Issue 120 2008Lyn Mikel Brown In this chapter we explore the phenomenon of "girls fighting like guys" by listening to adolescent girls' justification for physical fighting with other girls. We argue that physical girlfighting is a particular kind of gendered performance,a performance of identity that expresses, at least in part, an answer to the question, "Who am I?",that both perpetuates and challenges the usual notions of masculinity and femininity and the differential power associated with these discourses. We present a sociocultural approach to identity that we believe not only holds promise for helping us to understand girl-fighting behavior but also highlights the clear interrelationship between social identity and personal identity. We conclude by highlighting several implications of this analysis for those who work with girls (and boys) in educational and clinical settings. © Wiley Periodicals, Inc.
