Vulnerabilidade ao stress, depressão e agressividade nas forças policiais

Os agentes de Policia, são elementos expostos a vários fatores de Vulnerabilidade ao Stress, sendo este vivenciado de diferentes formas. Neste estudo procurou-se conhecer a relação entre a vulnerabilidade ao Stress, a Depressão e a Agressividade nas forças policiais. Participaram 350 indivíduos, 34 do sexo feminino e 316 do sexo maculino com uma média de idades de 25.80 (DP=5.28) e com uma média de serviço na PSP de 1.99 anos (DP=.46), selecionados por conveniência. Todos os participantes trabalham há um ano no serviço operacional. As medidas utilizadas no presente estudo foram a Depression Anxiety Stress Scale (D.A.S.S), criada por Lovibond e Lovibond em (1995), tendo sida traduzida e validada para portugês por Ribeiro e colaboradores (2004), a Escala de Vulnerabilidade ao Stress (23QVS) - foi desenvolvida por Vaz Serra, (2000), com o objectivo de auto-avaliar a vulnerabilidade ao stress em relação com a psicopatologia e o questionário de Agressividade (Aggression Questionnaire) foi criado por Buss e Perry (1992) , tendo sido traduzida e validada para a população portuguesa por Simões (1993). Os resultados obtidos no presente estudo indicam, em termos gerais e quanto maior é a vulnerabilidade ao stress maior é a agressividade e a sintomatologia depressiva.

Estratégias de resolução de conflitos em adolescentes angolanos e portugueses

Pretendemos estudar situações de conflito interpessoal e sócio-moral e comparar as estratégias de resolução que são escolhidas por adolescentes de contextos culturais diferentes. Participaram no estudo 89 adolescentes, 44 portugueses e 45 angolanos, com idades compreendidas entre os 14 e os 16 anos, distribuídos de forma equivalente pelos dois géneros. Foram construídos quatro dilemas que configuram situações de conflito interpessoal e moral habituais entre adolescentes (humilhação, inveja, rivalidade entre grupos e traição amorosa) e foram utilizadas quatro medidas, atribuição de comportamento e de emoção, perceção de ganhos e antecipação de custos. Os resultados revelaram que a escolha de estratégias de resolução de conflitos interpessoais (agressão física, agressão verbal, indiferença, negociação e outras) é insensível ao género, mas varia inter-medidas nas histórias de inveja e de traição, varia com o conteúdo sócio-moral das situações, sobretudo entre a história de traição amorosa e as outras histórias, e varia inter-culturas também para a história de traição, onde se verificam diferenças estatísticas nas três medidas. Os resultados mostram ainda que os adolescentes têm dificuldade em antecipar os custos associados às estratégias de resolução de conflitos interpessoais, pois optam maioritariamente por não responder a esta questão.

The effects of maternal depression and parental conflict on children's peer play

Background Little is known about the relative effects of exposure to postnatal depression and parental conflict on the social functioning of school-aged children. This is, in part, because of a lack of specificity in the measurement of child and parental behaviour and a reliance on children's reports of their hypothetical responses to conflict in play. Methods In the course of a prospective longitudinal study of children of postnatally depressed and well women, 5-year-old children were videotaped at home with a friend in a naturalistic dressing-up play setting. As well as examining possible associations between the occurrence of postnatal depression and the quality of the children's interactions, we investigated the influence of parental conflict and co-operation, and the continuity of maternal depression. The quality of the current mother-child relationship was considered as a possible mediating factor. Results Exposure to postnatal depression was associated with increased likelihood, among boys, of displaying physical aggression in play with their friend. However, parental conflict mediated the effects of postnatal depression on active aggression during play, and was also associated with displays of autonomy and intense conflict. While there were no gender effects in terms of the degree or intensity of aggressive behaviours, girls were more likely to express aggression verbally using denigration and gloating whereas boys were more likely to display physical aggression via interpersonal and object struggles. Conclusions The study provided evidence for the specificity of effects, with strong links between parental and child peer conflict. These effects appear to arise from direct exposure to parental conflict, rather than indirectly, through mother-child interactions.

Are you thinking what I’m thinking? Peer group similarities in adolescent hostile attribution tendencies

A bias towards attributing hostile intent to others has been linked to aggression. In an adolescent sample, we investigated whether peer group homophily exists in the tendency towards attributing hostile intent. We assessed hostile attribution tendencies and self-reported aggressive behaviours in a normative sample of 910 adolescents, and computed average peer group scores based on nominated friend scores. Results indicated that adolescents showed significant correlations between their own level of hostile attributions and that of their peer group. Further analyses indicated that this effect occurred specifically in reciprocal friendships, and was retained even once own and peer group level of aggression were controlled.

Return of the 'Angry Woman': authenticating female physical action in contemporary cinema

In 1999, Elizabeth Hills pointed up the challenges that physically active women on film still posed, in cultural terms, and in relation to certain branches of feminist theory . Since then, a remarkable number of emphatically active female heroes have appeared on screen, from 'Charlie’s Angels' to 'Resident Evil', 'Aeon Flux', and the 'Matrix' and 'X-Men' trilogies. Nevertheless, in a contemporary Western culture frequently characterised as postfeminist, these seem to be the ‘acceptable face’ – and body – of female empowerment: predominantly white, heterosexual, often scantily clad, with the traditional hero’s toughness and resolve re-imagined in terms of gender-biased notions of decorum: grace and dignity alongside perfect hair and make-up, and a body that does not display unsightly markers of physical exertion. The homogeneity of these representations is worth investigating in relation to critical claims that valorise such air-brushed, high-kicking 'action babes' for their combination of sexiness and strength, and the feminist and postfeminist discourses that are refracted through such readings. Indeed, this arguably ‘safe’ set of depictions, dovetailing so neatly with certain postfeminist notions of ‘having it all’, suppresses particular kinds of spectacles in relation to the active female body: images of physical stress and extension, biological consequences of violence and dangerous motivations are all absent. I argue that the untidy female exertions refused in popular “action babe” representations are now erupting into view in a number of other contemporaneous movies – 'Kill Bill' Vols 1 & 2, 'Monster', and 'Hard Candy' – that mark the return of that which is repressed in the mainstream vision of female power – that is, a more viscerally realistic physicality, rage and aggression. As such, these films engage directly with the issue of how to represent violent female agency. This chapter explores what is at stake at a representational level and in terms of spectatorial processes of identification in the return of this particularly visceral rendering of the female avenger.

An experimental investigation of peer influences on hostile attributions in adolescents

Aggression in young people has been associated with a bias towards attributing hostile intent to others; however, little is known about the origin of biased social information processing. The current study explored the potential role of peer contagion in the emergence of hostile attribution in adolescents. 134 adolescents were assigned to one of two manipulated ‘chat-room’ conditions, where they believed they were communicating with online peers (e-confederates) who endorsed either hostile or benign intent attributions. Adolescents showed increased hostile attributions following exposure to hostile e-confederates and reduced hostility in the benign condition. Further analyses demonstrated that social anxiety was associated with a reduced tendency to take on hostile peer attitudes. Neither gender nor levels of aggression influenced individual susceptibility to peer influence, but aggressive adolescents reported greater affinity with hostile e-confederates.

Thorn-dwelling ants provide antiherbivore defence for camelthorn trees, Vachellia erioloba, in Namibia

Ants are widely employed by plants as an antiherbivore defence. A single host plant can associate with multiple, symbiotic ant species, although usually only a single ant species at a time. Different plant-ant species may vary in the degree to which they defend their host plant. In Kenya, ant–acacia interactions are well studied, but less is known about systems elsewhere in Africa. A southern African species, Vachellia erioloba, is occupied by thorn-dwelling ants from three different genera. Unusually, multiple colonies of all these ants simultaneously and stably inhabit trees. We investigated if the ants on V. erioloba (i) deter insect herbivores; (ii) differ in their effectiveness depending on the identity of the herbivore; and (iii) protect the tree against an important herbivore, the larvae of the lepidopteran Gonometa postica. We show that experimental exclusion of ants leads to greater levels of herbivory on trees. The ants inhabiting V. erioloba are an effective deterrent against hemipteran and coleopteran, but not lepidopteran herbivores. Defensive services do not vary among ant species, but only Crematogaster ants exhibit aggression towards G. postica. This highlights the potential of the V. erioloba–ant mutualism for studying ant–plant interactions that involve multiple, simultaneously resident thorn-dwelling ant species.

Motion planning of autonomous vehicles in a non-autonomous vehicle environment without speed lanes

Planning is one of the key problems for autonomous vehicles operating in road scenarios. Present planning algorithms operate with the assumption that traffic is organised in predefined speed lanes, which makes it impossible to allow autonomous vehicles in countries with unorganised traffic. Unorganised traffic is though capable of higher traffic bandwidths when constituting vehicles vary in their speed capabilities and sizes. Diverse vehicles in an unorganised exhibit unique driving behaviours which are analysed in this paper by a simulation study. The aim of the work reported here is to create a planning algorithm for mixed traffic consisting of both autonomous and non-autonomous vehicles without any inter-vehicle communication. The awareness (e.g. vision) of every vehicle is restricted to nearby vehicles only and a straight infinite road is assumed for decision making regarding navigation in the presence of multiple vehicles. Exhibited behaviours include obstacle avoidance, overtaking, giving way for vehicles to overtake from behind, vehicle following, adjusting the lateral lane position and so on. A conflict of plans is a major issue which will almost certainly arise in the absence of inter-vehicle communication. Hence each vehicle needs to continuously track other vehicles and rectify plans whenever a collision seems likely. Further it is observed here that driver aggression plays a vital role in overall traffic dynamics, hence this has also been factored in accordingly. This work is hence a step forward towards achieving autonomous vehicles in unorganised traffic, while similar effort would be required for planning problems such as intersections, mergers, diversions and other modules like localisation.

A longitudinal study of child sleep in high and low risk families: relationship to early maternal settling strategies and child psychological functioning

Objectives To investigate whether sleep disturbances previously found to characterise high risk infants: (a) persist into childhood; (b) are influenced by early maternal settling strategies and (c) predict cognitive and emotional/behavioural functioning. Methods Mothers experiencing high and low levels of psychosocial adversity (risk) were recruited antenatally and longitudinally assessed with their children. Mothers completed measures of settling strategies and infant sleep postnatally, and at 12 and 18 months, infant age. At five years, child sleep characteristics were measured via an actigraphy and maternal report; IQ and child adjustment were also assessed. Results Sleep disturbances observed in high-risk infants persisted at five years. Maternal involvement in infant settling was greater in high risk mothers, and predicted less optimal sleep at five years. Poorer five year sleep was associated with concurrent child anxiety/depression and aggression, but there was limited evidence for an influence of early sleep problems. Associations between infant/child sleep characteristics and IQ were also limited. Conclusions Early maternal over-involvement in infant settling is associated with less optimal sleep in children, which in turn, is related to child adjustment. The findings highlight the importance of supporting parents in the early development of good settling practices, particularly in high-risk populations.

Cyber warfare: a multidisciplinary analysis

Cyber warfare is an increasingly important emerging phenomenon in international relations. The focus of this edited volume is on this notion of cyber warfare, meaning interstate cyber aggression, as distinct from cyber-terrorism or cyber-crime. Waging warfare in cyberspace has the capacity to be as devastating as any conventional means of conducting armed conflict. However, while there is a growing amount of literature on the subject within disciplines, there has been very little work done on cyber warfare across disciplines, which necessarily limits our understanding of it. This book is a major multidisciplinary analysis of cyber warfare, featuring contributions by world-leading experts from a mixture of academic and professional backgrounds.

The virtual world of exercises and deterrence

Miliary Exercises, Command Post Exercises and War Games serve to test procedures, but in some forms also serve to signal ability to defend against aggression, or to intimidate neighbours with the threat of aggression. Some indicators suggest that the solidarity of NATO and the EU is decreasing, and with it a plausible nuclear deterrence posture. This article discusses whether recent exercises and TV war games make matters better or worse.

Pasolini and Third World hunger: an approach to Cinema Novo through 'La ricotta'

Among the links between Pier Paolo Pasolini and Brazilian Cinema Novo, one of the most inspiring is the political approach to hunger and consumption. In this text, I analyse this topic to look at how some of the aesthetic ideas in Pasolini’s La ricotta (1963) can also be found in some of the most important films of Cinema Novo. In 'La ricotta' (1963), the irresistible need to eat of a subproletarian interacts and clashes with his responsibilities as an actor in a movie version of the Passion of Christ, so that the film creates a complex network of relations between film shooting, social differences, art, hunger, consumption, time and light, which turns the film set into a space for displaying political relations, differences, exploitation and revolution. The correspondences between these concepts and some aggression techniques of Cinema Novo are numerous and confirm the capacity of Pasolini’s film to project ideas on cinema and politics beyond its particular production context.
