Understanding the cycle of violence: an examination of bully and victim social roles in early childhood

The purpose of this study was to assess the prevalence of bullying and victimization in a metropolitan area. A cross-sectional study with kindergarten (n = 127) and first grade (n = 126) children was conducted in two Miami-Dade County Public Schools and three private schools in the same area. Bullying and victimization behavior and social acceptance were assessed through peer nomination and the mental health outcomes of depression and anxiety were assessed through children's self-report. Teachers and parents also completed a social behavior scale for each child. Three areas of analyses were conducted pertaining to membership classification of social roles and the social acceptance and mental health outcomes associated with those roles, reporter agreement within the social roles, and the psychometric properties of the Childhood Social Behavior Scale. Results showed an overall negative pattern of adjustment for children identified as a member of any of the negative social roles. Also, the results support a new analytic approach to the investigation of social roles. The implication of these findings for early identification, social policy, and effective prevention strategies are discussed.

Improving safety of nursing staff: challenges and solutions regarding safety for nursing staff in acute care psychiatric settings

Workplace violence is defined as an act of abuse, threatening behaviour, intimidation, or assault on a person in his or her place of employment. Unfortunately, such violence is a reality for nurses. These take the form of physical, verbal, and threating behaviours, and harassment. Violence, particularly verbal abuse, is so prevalent that it is often considered “part of the job” and can contribute to many negative professional and personal effects for nurses. Therefore, it is important to understand what influences an individual to become violent in order to suggest and support initiatives to decrease it. A literature review and consultations with key stakeholders were conducted to gather relevant information regarding violence committed by patients and others visiting mental health care settings. Through data analysis, two relevant themes were revealed: reporting and interventions. Reporting incidents of workplace violence is important to track and quantify aggressive episodes, thus emphasizing its seriousness. Nurses may differ in the perception of what constitutes violence, underreport incidents, and feel a sense of futility when reported violence continues. In addition, cumbersome methods of reporting can be a hindrance to the reporting process. Six areas of potential interventions were identified to increase safety for nurses. These are staffing, de-escalation training, environmental considerations, addictions services, organizational support, and consequences. All findings were summarized in a document to be presented to the leadership of the Mental Health and Addictions program within the local health care authority. The goal is to offer recommendations to lead to a decrease in workplace aggression and increased safety for nurses in the acute care psychiatric setting.

Effect of reading sport chronicles on the perception of justice and the predisposition to protest actions in soccer

In this study three chronicles from national newspapers (one generalist and two sport press) were analyzed. The chronicles belong to Spain’s soccer final of the King’s Cup in 2014. The aim of the study was to know if there was any influence on the readers’ perception of justice and consequently if this influence could cause a particular predisposition to participate in acts of protest. 462 university students participated. The results showed that different chronicles caused differences in the perception of justice depending on the chronicle read. However, a clear influence on the willingness to participate in acts of protest was not obtained. These results should make us think about the impact of sport press and its influence, and to be aware of the indirect responsibility of every sector on the antisocial behaviors generated by soccer in our country.

Cyberbullying: estudo da prevalência de comportamentos de cyberbullying e sua relação com vivências de vergonha e estados emocionais negativos

Objectivos: O presente estudo tem como principal objectivo avaliar a prevalência dos comportamentos de cyberbullying, analisando a influência de variáveis sóciodemográficas, e, compreender a sua relação com as vivências de vergonha interna e externa e com os estados emocionais negativos, particularmente a depressão, a ansiedade e o stress. Método: Para a recolha de dados recorreu-se a uma mostra de adolescentes (N=131) a frequentar o 3º ciclo do ensino básico, com idades compreendidas entre os 12 e os 18 anos (M= 13,76; DP= 1,25). O protocolo de avaliação foi constituído por um questionário psicossocial desenvolvido especificamente para este estudo e por um conjunto de medidas fidedignas para avaliar o cyberbullying (CBQ e CBQ-V), a vergonha interna (ISS), vergonha externa (OAS) e os estados emocionais negativos (DASS-21). Resultados: Os nossos dados revelaram que 76 adolescentes (58%) exerceram um qualquer comportamento de cyberbullying (com um predomínio dos rapazes), enquanto 50 adolescentes (38,2%) já foram vítimas de um qualquer comportamento de cyberbullying (com igual proporção entre rapazes e raparigas). Manter lutas e discussões online, usando insultos mediante mensagens electrónicas foi o comportamento praticado mais frequente (30,5%), enquanto o ser removido intencionalmente de um grupo online foi o comportamento sofrido mais frequente (16,1%). A idade e os anos de reprovações mostraram uma associação positiva com os comportamentos de agressão por cyberbullying. Foi ainda analisada a sobreposição entre a execução e a vitimização de comportamentos de cyberbullying, tendo sido discriminados quatro grupos de adolescentes: só agressores (adolescentes que apenas exerceram comportamentos de agressão), só vítimas (apenas sofreram comportamentos de cyberbulling), vítimas e agressores (adolescentes que são simultaneamente agressores e vítimas), e nem vítimas nem agressores (adolescentes que não exerceram nem sofreram qualquer comportamento de cyberbullying). Os resultados evidenciaram que quanto maior a frequência de comportamentos de agressão por cyberbullying, maior a vergonha interna e maior os níveis de stress demonstrados. Por sua vez, quanto maior a frequência de vitimização por cyberbullying, maior a vergonha interna e externa, bem como maior os níveis de ansiedade e stress. Conclusão: Devido a complexidade do fenómeno cyberbullying e seu recente surgimento, serão necessários mais estudos, particularmente longitudinais, para compreender a relação antecedente e/ou consequentes aos comportamentos de cyberbullying entre estados emocionais negativos e as experiências de vergonha. / Objectives: The present study has as main objective to assess the prevalence of cyberbullying behaviours, analyzing the influence of socio demographic variables, and, understand its relationship to the experiences of internal and external shame and negative emotional states, particularly depression, anxiety and stress. Method: For data collection we used a sample of adolescents (N=131) attending the 3rd cycle of basic education, aged between 12 and 18 years (M=13,76; SD=1,25). The evaluation protocol consisted of a psychosocial questionnaire developed specifically for this study and a set of reliable measure to assess cyberbullying (CBQ and CBQ-V), internal shame (ISS), external shame (OAS) and the emotional states negative (DASS-21). Results: Our data indicate that 76 adolescents (58%) exerted any conduct of a cyberbullying (with a predominance of boys), while 50 adolescents (38,2%) had been victims of cyberbullying behaviour of any one (with an equal ratio of boys and girls). Keep fighting and discussions online, through e-mails using insults behaviour was practiced more often (30,5%), while being intentionally removed a group of online behaviour is seen more frequently (16,1%). The age and years of failures were positively associated with the behaviours of aggression by cyberbullying. Was further examined the overlap between enforcement and victimization of cyberbullying behaviours, having been discriminated four groups of adolescents: only aggressors (adolescents who have had only aggressive behaviour), only victims (only suffered cyberbullying behaviours), victims and aggressors (adolescents who are both perpetrators and victims), and neither victims nor aggressors (adolescents who did not exercise any behaviour or suffered cyberbullying). Results showed that the higher the frequency of aggression by cyberbullying behaviour, the greater shame and internal stress levels demonstrated. In turn, the higher the frequency of cyberbullying victimization, the greater the shame internal and external, as well as higher levels of anxiety and stress. Conclusion: Due to the complexity of the phenomenon cyberbullying and its recent emergence, further studies are needed, particularly longitudinal, to understand the relationship between antecedent and/or consequential to cyberbullying behaviours between negative emotional states and experiences of shame.

A multi-component pheromone in the urine of dominant male tilapia (Oreochromis mossambicus) reduces aggression in rivals

Males often use scent to communicate their domi- nance, and to mediate aggressive and breeding behaviors. In teleost fish, however, the chemical composition of male pher- omones is poorly understood. Male Mozambique tilapia, Oreochromis mossambicus, use urine that signals social status and primes females to spawn. The urinary sex pheromone di- rected at females consists of 5β-pregnane-3α,17α,20β-triol 3- glucuronate and its 20α-epimer. The concentration of these is positively correlated with male social rank. This study tested whether dominant male urine reduces aggression in receiver males, and whether the pregnanetriol 3-glucuronates also re- duce male-male aggression. Males were allowed to fight their mirror image when exposed to either: i) water control or a chemical stimulus; ii) dominant male urine (DMU); iii) C18- solid phase (C18-SPE) DMU eluate; iv) C18-SPE DMU eluate plus filtrate; v) the two pregnanetriol 3-glucuronates (P3Gs); or vi) P3Gs plus DMU filtrate. Control males mounted an increas- ingly aggressive fight against their image over time. However, DMU significantly reduced this aggressive response. The two urinary P3Gs did not replicate the effect of whole DMU. Neither did the C18-SPE DMU eluate, containing the P3Gs, alone, nor the C18-SPE DMU filtrate to which the two P3Gs were added. Only exposure to reconstituted DMU (C18-SPE eluate plus filtrate) restored the aggression-reducing effect of whole DMU. Olfactory activity was present in the eluate and the polar filtrate in electro-olfactogram studies. We conclude that P3Gs alone have no reducing effect on aggression and that the urinary signal driving off male competition is likely to be a multi-component pheromone, with components present in both the polar and non-polar urine fractions.

Friendship dynamics and popularity hierarchies among inclusive men

Previous research has demonstrated that aggression and marginalization are key components of maintaining popularity within male peer groups. However, more recent ethnographic studies have documented a significant shift in young men’s attitudes and behaviours, with more inclusive masculinities flourishing. My previous research has examined friendship dynamics and popularity hierarchies among boys, showing that contemporary popularity is stratified by a boy’s charisma, authenticity, emotional support, and social fluidity. In this article, I draw upon ethnographic research to provide an intersectional analysis of how adolescent masculinities are influenced by class, age and sexuality

Environmental enrichment reduces aggression of pearl cichlid, Geophagus brasiliensis, during resident-intruder interactions

Em lutas entre peixes residentes e intrusos, residentes geralmente vencem, provavelmente porque valorizam o território mais do que os intrusos. Nós aventamos a hipótese de que ambientes enriquecidos aumentam o valor da área em disputa, levando os residentes a defenderem mais violentamente ambientes enriquecidos de recursos do que ambientes empobrecidos, pois possuiriam mais motivação para mantê-lo. No entanto, no presente estudo, ao testarmos as interações entre intrusos e residentes em acarás, Geophagus brasiliensis, observamos que o enriquecimento ambiental reduz a agressividade e pode levar a cohabitação entre os peixes, sem luta. Adicionalmente, em nossos experimentos, o efeito da residência prévia ocorreu independente da condição de enriquecimento. A diminuição das interações entre os peixes e, consequentemente, a diminuição do nível de agressividade é aqui atribuída aos efeitos da diminuição da visibilidade entre os peixes devido ao aumento de complexidade do ambiente.

Comportamentos agressivos entre pares e padrões de vinculação : Um estudo com jovens adolescentes

Embora de natureza radicalmente distinta, bullying e vinculação são fenómenos de natureza relacional. Se o bullying é descrito como um abuso sistemático de poder, que ocorre intencional e repetidamente entre pares, a vinculação refere-se ao estabelecimento de laços afectivos fortes com determinadas pessoas significativas, especialmente em momentos percepcionados como perigosos. A investigação, apesar do reduzido número de estudos, mostra uma relação entre estes conceitos. A agressão instrumental interpares parece estar relacionada com vinculações inseguras. O objectivo deste estudo é compreender a relação entre o bullying e os padrões de vinculação. Foi realizado em três escolas da zona de Évora, com os alunos do 7° ano (237 alunos). Utilizaram-se dois questionários de auto-relato: o QEVE - Questionário de Exclusão Social e Violência Escolar e o IVIA - Inventário sobre Vinculação para a Infância e a Adolescência. Os resultados deste estudo corroboram os estudos anteriores, relativamente aos comportamentos agressivos entre pares. Mostram que existem correlações estatisticamente significativas entre as dimensões da vitimação e da agressão e, ainda, verificou-se que a vinculação segura parece funcionar como um factor protector para a vitimação e a agressividade e a vinculação ansiosa parece relacionar-se com a vitimação. ABSTRACT: Although radically different, bullying and attachment are relational in nature phenomena. lf the bullying is described as a systematic abuse of power, which is intentionally and repeatedly between peers, attachment refers to the establishment of strong emotional ties with certain significant others, especially at times perceived as dangerous. The research, despite the small number of studies show a relationship between these concepts. Instrumental peer aggression seems to be associated with insecure attachments. The aim of this study is to understand the relationship between bullying and patterns of binding. lt was conducted in three schools in the district of Évora with the students of 7th Grade (237 students). We used two questionnaires self-report: the QEVE - Questionnaire of Social Exclusion and Violence in School and IVIA - lnventory on Attachment for Children and Adolescents. These results corroborate previous studies, for aggressive behavior among peers. Show that there are statistically significant correlations between the dimensions of victimization and aggression and also found that a secure attachment appears to be a protective factor for victimization and aggression and anxious attachment seems to relate to the victimization.

Modelos organizadores do pensamento: uma perspectiva de pesquisa sobre o raciocínio moral com adolescentes autores de infração

This article has the aim to expand the perspective of research in the field of morality. We present a proposal of morality study of outlaw teenagers according to Thinking Organizer Models Theory. Through the idea of complexity we search to understand the cognitive process in the elaboration of moral reasoning inside situations of conflict. With this perspective, we developed a research that aimed to identify which organizer models were applied by 20 outlaw male teenagers who abide by social punishment to solve the hypothetical moral conflicts. Through interviews we told them a situation of moral conflict that involved friendship relation, physical aggression and steal. We could identified several models which were joined in three categories. Such models reflected the diversity and regularity that are present inside the elaborated reasoning to solve the conflicts shown by us. We conclude that the diversity of organizer models identified shows the importance of the contents in the construction of moral reasoning.

Sweeper polyps of the coral Goniopora tenuidens (Scleractinia : Poritidae)

The massive coral Goniopora tenuidens can develop elongated sweeper polyps. These are thought to be involved in aggressive interactions with neighbouring benthic organ isms, like the sweeper tentacles of other corals. The cnidoms of sweeper polyps and ordinary polyps of G. tenuidens from the Great Barrier Reef were compared. Sweeper polyps had significantly greater densities of elongate holotrichous isorhizas (34577 +/- 3839/mg; mean +/- SD, n = 6) than ordinary polyps (936 +/- 371/mg; p < 0.05), while ordinary polyps had significantly greater densities of spirocysts (75994 +/- 15992/mg) than sweeper polyps (19469 +/- 7808/mg; p < 0.05). This suggests that sweeper polyps of G. tenuidens, like the sweeper tentacles of other corals, are modified for aggression, and that they probably act through nematocyst discharge. However, the scattered distribution of sweeper polyps observed on colonies of G. tenuidens in the field suggests that sweeper polyps may have other functions.

Alcohol consumption in homicide victims in the city of Sao Paulo

Aims To assess the association between alcohol use and victimization by homicide in individuals autopsied at the Institute of Legal Medicine in Sao Paulo, Brazil. Design Cross-sectional study. Setting Excessive consumption of alcohol is a serious public health issue and a major factor in triggering violent situations, which suggests a strong association between alcohol ingestion and becoming a victim of homicide. Participants Data from 2042 victims of homicides in 2005 were obtained from medical examiner reports. Measurements The victim`s gender, age, ethnicity and blood alcohol concentration (BAC) were collected. The method of death and homicide circumstances, as well as the date, time and place of death were also studied. Findings Alcohol was detected in blood samples of 43% of the victims, and mean BAC levels were 1.55 +/- 0.86 g/l. The prevalence of positive BAC levels was higher among men (44.1%) than women (26.6%), P < 0.01. Firearms caused most of the deaths (78.6%), and alcohol consumption was greater among victims of homicide by sharp weapons (P < 0.01). A greater proportion of victims with positive BAC were killed at weekends compared to weekdays (56.4 and 38.5%, respectively; P < 0.01), and the correlation between homicide rates and the average BAC for the central area of the city was positive (r(s) = 0.90; P < 0.01). Conclusions These results highlight alcohol as a contributing factor for homicide victimization in the greatest urban center in South America, supporting public strategies and future research aiming to prevent homicides and violence related to alcohol consumption.

Downregulation of CD9 protein expression is associated with aggressive behavior of oral squamous cell carcinoma

Squamous cell carcinoma of the oral cavity (OSCC) is a malignancy characterized by a high degree of local aggression and metastasis to cervical lymph nodes. Tetraspanins are proteins with functional roles in a wide array of cellular processes and are reported to be associated with tumor progression. The present study investigated the expression of the CD9, CD37, CD63, CD81 and CD82 tetraspanins in OSCC using immunohistochemistry (IHC) and quantitative Real Time-PCR (qRT-PCR). Tissue microarray (TMA) analysis of samples from 179 cases of OSCC and 10 normal samples oral mucosa were evaluated immunomorphologically. We analyzed CD9 and CD82 expression by qRT-PCR in 66 OSCC cases and 4 normal samples of oral mucosa. Expression of CD63, CD37 and CD81 was not detected in the samples studied. CD82 was downregulated or negative in 127 of 179 (80%) specimens; no correlation was observed between CD82 expression, clinicopathological parameters, disease-free survival and 5-year overall survival. CD9 expression was downregulated or negative in 75 of 129 (42%) OSCC samples. Loss of CD9 expression in OSCC samples correlated with the incidence of lymph node metastasis (p = 0.017). Disease-free survival and the 5-year overall survival of patients with downregulated or negative CD9 expression were significantly lower than in patients with positive CD9 expression (p = 0.010 and p = 0.071, respectively). No correlation was found between CD9 or CD82 expression and clinicopathological parameters by qRT-PCR. Our results suggest that the downregulation or lack of expression of the CD9 protein might indicate a more aggressive of OSCC. (C) 2009 Elsevier Ltd. All rights reserved.

Carbamazepine augmentation for schizophrenia: How good is the evidence?

Background: Augmentation strategies in schizophrenia treatment remain an important issue because despite the introduction of several new antipsychotics, many patients remain treatment resistant. The aim of this study was to undertake a systematic review and meta-analysis of the safety and efficacy of one frequently used adjunctive compound: carbamazepine. Data sources and study selection: Randomized controlled trials comparing carbamazopine (as a sole or as an adjunctive compound) with placebo or no intervention in participants with schizophrenia or schizoaffective disorder were searched for by accessing 7 electronic databases, cross-referencing publications cited in pertinent studies, and contacting drug companies that manufacture carbamazepine. Method: The identified studies were independently inspected and their quality assessed by 2 reviewers, Because the study results were generally incompletely reported, original patient data were requested from the authors; data were received for 8 of the 10 randomized controlled trials included in the present analysis, allowing for a reanalysis of the primary data. Dichotomous variables were analyzed using the Mantel-Haenszel odds ratio and continuous data were analyzed using standardized mean differences, both specified with 95% confidence intervals. Results: Ten studies (total N = 283 subjects) were included. Carbamazepine was not effective in preventing relapse in the only randomized controlled trial that compared carbamazepine monotherapy with placebo. Carbamazepine tended to be less effective than perphenazine in the only trial comparing carbamazepine with an antipsychotic. Although there was a trend indicating a benefit from carbamazepine as an adjunct to antipsychotics, this trend did not reach statistical significance. Conclusion: At present, this augmentation strategy cannot be recommended for routine use. The most promising targets for future trials are patients with excitement, aggression, and schizoaffective disorder bipolar type.

Putting the group back into unions: A social psychological contribution to understanding union support

Industrial relations research that attempts to grapple with individuals' union-related sentiments and activities often draws on one of two traditions of psychological research—the individual-level factors tradition (for example, personality and attitude-behaviour relations) and the social context tradition (for example, frustration-aggression and relative deprivation). This paper provides an overview of research conducted from within these traditions to explain union-related phenomena and identifies some of the limitations that arise as a consequence of a shared tendency to treat people in an atomistic fashion. The paper argues for an understanding of the psychological processes that underpin group-based action. To this end, it elaborates a theoretical framework based on social identity theory and self-categorisation theory that would allow us to examine the dynamic interplay between the individual, their cognitions and their environment. The paper concludes with a brief discussion of a specific case of union mobilisation, to indicate how this theoretical framework might aid empirical analysis.

" (...) mais gosto de ti??? Diferenças entre homens e mulheres nas crenças e comportamentos sobre violência conjugal

O presente trabalho tem como objectivo analisar as diferenças de género nas crenças e comportamentos relacionados com a violência conjugal, fazendo uma avaliação de condutas e atitudes face ao fenómeno. Participaram no estudo 50 casais, que preencheram o Inventário de Violência Conjugal e a Escala de Crenças sobre Violência Conjugal. Os resultados apontam para a não existência de diferenças entre homens e mulheres na perpetração e vitimação de violência em relações íntimas. São os homens os que mais facilmente legitimam os comportamentos violentos, embora a tendência atitudinal flua no sentido de não a aprovar. ABSTRACT:This study aims to examine gender differences in beliefs and behaviors related to domestic violence, by making an assessment of behaviors and attitudes addressing the phenomenon. 50 couples supported the study by filling Inventário de Violência Conjugal and Escala de Crenças sobre Violência Conjugal. The results indicate that there are no substancial differences between men and women in the perpetration and victimization of violence in intimate relationships. Men are more easily prone to accredit violent behavior, although the sight tendency is not to approve.
