New community-based initiatives being developed to address violent extremism in the United States are utilizing mental health services and leadership. This article reviews current approaches to preventing violent extremism, the contribution that mental illness and psychosocial problems can make to violent extremism, and the rationale for integrating mental health strategies into preventing violent extremism. The authors describe a community-based targeted violence prevention model and the potential roles of mental health professionals. This model consists of a multidisciplinary team that assesses at-risk individuals with comprehensive threat and behavioral evaluations, arranges for ongoing support and treatment, conducts follow-up evaluations, and offers outreach, education, and resources for communities. This model would enable mental health professionals in local communities to play key roles in preventing violent extremism through their practice and leadership.

Currently, threats to societal security from extremist groups are high on the political agenda in many countries. Politicians, policymakers at various levels and communities are searching for methods to counteract recruitment to violent organizations. These efforts are often referred to as Prevention of Violent Extremism (PVE-programmes). One of…
Full Text Available The paper presents the differences in the nature of extremism and radicalism, and the necessity of introducing the concept of "violent extremism." It is shown that the ideology is the explanation of extremist behavior, rather than its cause. The ideology of extremism often eclectic, contradictory and can easily be transformed by changing the object of hostility, depending on the situation. For the description of the psychological causes of extremism it is proposed to use the concept of personal disposition. Disposition is the preferred way to subjective interpretation of reality and reflects both the specific needs of a person as well the typical social situations where it realized and personal experience. Considered the following dispositions of violent extremism: the Cult of force and aggression, Intolerance, Out-group hostility Conventional coercion, Social pessimism and destructiveness, Mystical, Fighting and overcoming, Nihilism to law, Anti-subjectivism. It is proposed to use these dispositions as diagnostic criteria and for preventing and correcting.

Full Text Available In this Research Paper Dr. Bibi van Ginkel takes an in depth look at how multi-lateral institutions, engage with civil society to counter violent extremism. Dr. van Ginkel argues that civil society can play a crucial role in preventing and countering violent extremism in numerous ways – by working on development programs, through their work in conflict transformation, in providing a platform to raise political grievances and to facilitate dialogue, or through their work in empowering victims and survivors of terrorism. The Paper finds that over the last decade there has been a more intensive coordination of activities between the UN and other multi-lateral organisations and civil society but the question remains whether the implementation as well as the drafting of these policies will live up to their potential effectiveness. This Paper gauges how effective these measures have been and what more there is to do. The final section concludes with a series of policy recommendations.

In developed countries, the majority of all violent crime is committed by a small group of antisocial recidivistic offenders, but no genes have been shown to contribute to recidivistic violent offending or severe violent behavior, such as homicide. Our results, from two independent cohorts of Finnish prisoners, revealed that a monoamine oxidase A (MAOA) low-activity genotype (contributing to low dopamine turnover rate) as well as the CDH13 gene (coding for neuronal membrane adhesion protein) are associated with extremely violent behavior (at least 10 committed homicides, attempted homicides or batteries). No substantial signal was observed for either MAOA or CDH13 among non-violent offenders, indicating that findings were specific for violent offending, and not largely attributable to substance abuse or antisocial personality disorder. These results indicate both low monoamine metabolism and neuronal membrane dysfunction as plausible factors in the etiology of extreme criminal violent behavior, and imply that at least about 5–10% of all severe violent crime in Finland is attributable to the aforementioned MAOA and CDH13 genotypes.

To determine exposure of young adolescents to extremely violent movies. Cross-sectional school-based survey of middle school students at 15 randomly selected New Hampshire and Vermont middle schools. Each survey contained a unique list of 50 movies, randomly selected from 603 top box office hits from 1988 to 1999, 51 of which were determined by content analysis to contain extremely violent material. Movie titles only were listed, and adolescents were asked to indicate which ones they had seen. Each movie appeared on approximately 470 surveys. We calculated the percentage of students who had seen each movie for a representative subsample of the student population. We also examined characteristics associated with seeing at least one extremely violent movie. Complete survey information was obtained from 5,456 students. The sample was primarily white and equally distributed by gender. On average, extremely violent movies were seen by 28% of the students in the sample (range 4% to 66%). The most popular movie, Scream, was seen by two-thirds of students overall and over 40% of fifth-graders. Other movies with sexualized violent content were seen by many of these adolescents. Examples include The General's Daughter (rated R for "graphic images related to sexual violence including a rape scene and perverse sexuality") and Natural Born Killers (rated R for "extreme violence and graphic carnage, shocking images, language, and sexuality"), seen by 27% and 20%, respectively. Older students, males, those of lower socioeconomic status, and those with poorer school performance were all significantly more likely to have seen at least one extremely violent movie. This study documents widespread exposure of young adolescents to movies with brutal, and often sexualized, violence. Given that many of these films were marketed to teens, better oversight of the marketing practices of the film industry may be warranted.
Full Text Available The case of a civil society actor on Twitter entering a securitized discourse on terrorism illustrates the transformative theoretical potential that emerges from new forms of communication online. Through a qualitative analysis of tweets from the Average Mohamed profile, the potential to change a negative narrative of violent extremism operating within a securitised discourse of Islamic terrorism, is discussed in an online context. The arguments forming from this analysis offers a new approach to studying online counter narratives by linking a theoretical framework of securitisation and de-securitisation to recent political efforts Countering Violent Extremism (CVE and Preventing Violent Extremism (PVE. Through the inclusion of a civil society Twitter account as an illustrative case, this paper explores how social media can challenge existing assumptions of who can be a de-securitising actor within security theory by blurring the lines between political and societal sectors in a securitised threat from Islamic terrorism. If and how a civil society actor can loosen the dichotomous discursive relationship between Self/Other relations within a contemporary discourse on terrorism becomes relevant for a theoretical discussion by presenting an argument suggesting that online CVE polices are more effective within the sphere of ‘normal’ politics rather than within the realm of securitization. This theoretical perspective offers an analytical framework including a wide range of actors involved in counter narratives policies which is useful for further CVE research.
Alex P. Schmid
Full Text Available In this Research Paper, Research Fellow Dr. Alex P. Schmid seeks to clarify some conceptual issues that tend to obscure the debate about how best to counter violent extremism. The main focus of this Research Paper is on obtaining a clearer understanding of what “Islamist extremism” entails in the context of the ongoing debate on allegedly “acceptable” non-violent extremists and “unacceptable” violent extremists. The author discusses a number of conceptualisations of religious extremism in the context of liberal democracies and also distinguishes, inter alia, between merely “not (yet violent” militancy and principled non-violent political activism in the Gandhian tradition. The author argues that the distinction between “non-violent extremism” and “violent extremism” is not a valid one. The paper provides a set of twenty indicators of extremism that can be used as an instrument for monitoring extremist statements and actions, with an eye to challenging and countering such non-democratic manifestations.

Full Text Available In the complex of motivating variables that define the push and pull factors behind recruitment and participation in civil conflict, "radicalization"—or "violent extremism"—is not conceived as a very strong motive, as is the case with studies on terrorism. As part of disarming youth combatants,the linkages between reintegration outcomes and possible rerecruitment into radical and extremist violence must be better understood to mitigate such risks. In our analysis, the policies guiding reintegration of child soldiers and youth should be better attuned to the relationship between recruitment motivations and reintegration outcomes, and must be approached from a political lens rather than a purely technical one. The risk of radicalization and involvement in violent extremism is ultimately a structural challenge, which needs to address root causes of recruitment rather than trying to find a solution through a band-aid approach of stopgap reintegration assistance.
Extreme overvalued beliefs (EOB) are rigidly held, non-deusional beliefs that are the motive behind most acts of terrorism and mass shootings. EOBs are differentiated from delusions and obsessions. The concept of an overvalued idea was first described by Wernicke and later applied to terrorism by McHugh. Our group of forensic psychiatrists (Rahman, Resnick, Harry) refined the definition as an aid in the differential diagnosis seen in acts of violence. The form and content of EOBs is discussed as well as group effects, conformity, and obedience to authority. Religious cults such as The People's Temple, Heaven's Gate, Aum Shinrikyo, and Islamic State (ISIS) and conspiracy beliefs such as assassinations, moon-hoax, and vaccine-induced autism beliefs are discussed using this construct. Finally, some concluding thoughts on countering violent extremism, including its online presence is discussed utilizing information learned from online eating disorders and consumer experience.
Full Text Available The principal object of this paper is to study the effects of extremist propensity, exposure to extremist moral settings and their interaction effect on political violence in sub groups by gender and immigrant background. The situational action theory, as outlined by Wikström is used as a framework. Although previous studies have found empirical evidence for this interaction effect in the light of general offending, no study so far has applied SAT to the study of violent extremism. In doing so, we will also address the stability of the interaction effect by gender and immigrant background. The present study is based on a large web survey on self-reported political violence as a measure for violent extremism. Strong support is found for the hypothesis that the effect of exposure to violent extremist moral settings is depending on the strength or weakness of individual violent extremist propensity. This indicates that exposure to violent extremist moral settings has the strongest effect on political violence for individuals with a high propensity to violent extremism. These results imply that SAT can be used to as a framework to explain individual violent extremism. This pattern is found for boys and girls of both native (Belgian and immigrant background.

Full Text Available Over the past decade, analysts have proposed several frameworks to explain the process of radicalization into violent extremism (RVE. These frameworks are based primarily on rational, conceptual models which are neither guided by theory nor derived from systematic research. This article reviews recent (post-9/11 conceptual models of the radicalization process and recent (post-9/11 empirical studies of RVE. It emphasizes the importance of distinguishing between ideological radicalization and terrorism involvement, though both issues deserve further empirical inquiry. Finally, it summarizes some recent RVE-related research efforts, identifies seven things that social science researchers and operational personnel still need to know about violent radicalization, and offers a set of starting assumptions to move forward with a research agenda that might help to thwart tomorrow's terrorists.
This chapter takes stock of what we do and do not know from primary sources about individuals’ disengagement from violent extremism. It points to three broad patterns: doubts related to the binary nature of the extremist world view, disappointment with peers or leaders, and changing personal...... priorities. The chapter shows how, for example, first-hand exposure to extremist violence or being condemned by mainstream society can either reinforce radicalization or expedite disengagement and argues that one-size-fits-all counterterrorism measures should be supplanted by a differentiated approach...

Full Text Available How do normal people become able to torture others? In order to explain this puzzling social phenomenon, we have to take secrecy – the characteristic trait of modern torture – as the lynchpin of the analysis. Following Georg Simmel’s formal analysis of the “secret society”, the contribution reconstructs structural and cultural aspects of the secret society of torturers that generate social processes that allow its members to behave extremely violently, forcing individuals to turn into torturers. The contribution argues that the form of social behaviour that we call torture is socially shaped. It goes beyond social psychology to develop an explanation from the perspective of relational sociology.

In the rapidly growing home health and hospice industry, little is known about workplace violence prevention (WVP) training and violent events. We examined the characteristics of WVP training and estimated violent event rates among 191 home health and hospice care providers from six agencies in California. Training characteristics were identified from the Occupational Safety and Health Administration guidelines. Rates were estimated as the number of violent events divided by the total number of home visit hours. Between 2008 and 2009, 66.5% (n = 127) of providers reported receiving WVP training when newly hired or as recurrent training. On average, providers rated the quality of their training as 5.7 (1 = poor to 10 = excellent). Among all providers, there was an overall rate of 17.1 violent events per 1,000 visit-hours. Efforts to increase the number of home health care workers who receive WVP training and to improve training quality are needed. © 2015 Wiley Periodicals, Inc.

Geophysical hazard is potentially damaging natural event and/or phenomenon, which may cause the loss of life or injury, property damage, social and economic disruption, or environmental degradation. Extreme natural hazards are a key manifestation of the complex hierarchical nonlinear Earth system. An understanding, accurate modeling and forecasting of the extreme hazards are most important scientific challenges. Several recent extreme natural events (e.g., 2004 Great Indian Ocean Earthquake and Tsunami and the 2005 violent Katrina hurricane) demonstrated strong coupling between solid Earth and ocean, and ocean and atmosphere. These events resulted in great humanitarian tragedies because of a weak preventive disaster management. The less often natural events occur (and the extreme events are rare by definition), the more often the disaster managers postpone the preparedness to the events. The tendency to reduce the funding for preventive disaster management of natural catastrophes is seldom follows the rules of responsible stewardship for future generations neither in developing countries nor in highly developed economies where it must be considered next to malfeasance. Protecting human life and property against earthquake disasters requires an uninterrupted chain of tasks: from (i) understanding of physics of the events, analysis and monitoring, through (ii) interpretation, modeling, hazard assessment, and prediction, to (iii) public awareness, preparedness, and preventive disaster management.

Full Text Available Indonesia has experimented with initiatives aimed at countering violent extremism (CVE since the wave of arrests following the first Bali bombing attack in 2002. Initial efforts involved police attempting to develop relationships of trust with terrorists in custody. Today, a broader range of strategies are employed, from promoting peace among youth and thwarting the allure of extremist narratives, to managing prisoners and assisting former terrorists reintegrate with society. The lead government body since 2010 has been the national counterterrorism agency, Badan Nasional Penanggulangan Terorisme (BNPT, which is tasked with coordinating stakeholders in Indonesia’s struggle with domestic terrorism. But managing the divergent and sometimes competing interests of Indonesia’s large state institutions has not been straightforward, and effective collaboration between relevant state agencies remains an obstacle to the success of CVE initiatives. Where government has fallen short, civil society organisations (CSOs often fill the gaps, and a number of dedicated practitioners now have invaluable experience, local contacts, and the specific knowledge required for countering extremism in the Indonesian context. CSOs also possess greater levels of trust among the communities they engage than security-centric state agencies could possibly hope to achieve. Yet instead of exploiting these civil society resources, the BNPT has largely preferred an independent (and top-down approach to CVE initiatives, collaborating if and when assistance is required. The Indonesian government should make better use of the unique legitimacy and expertise of civil society organisations.

Context: Lower extremity injuries are common in basketball, yet it is unclear how prophylactic interventions affect lower extremity injury incidence rates. Objective: To analyze the effectiveness of current lower extremity injury prevention programs in basketball athletes, focusing on injury rates of (1) general lower extremity injuries, (2) ankle sprains, and (3) anterior cruciate ligament (ACL) tears. Data Sources: PubMed, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Register of Controlled Trials were searched in January 2015. Study Selection: Studies were included if they were randomized controlled or prospective cohort trials, contained a population of competitive basketball athletes, and reported lower extremity injury incidence rates specific to basketball players. In total, 426 individual studies were identified. Of these, 9 met the inclusion criteria. One other study was found during a hand search of the literature, resulting in 10 total studies included in this meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 2. Data Extraction: Details of the intervention (eg, neuromuscular vs external support), size of control and intervention groups, and number of injuries in each group were extracted from each study. Injury data were classified into 3 groups based on the anatomic diagnosis reported (general lower extremity injury, ankle sprain, ACL rupture). Results: Meta-analyses were performed independently for each injury classification. Results indicate that prophylactic programs significantly reduced the incidence of general lower extremity injuries (odds ratio [OR], 0.69; 95% CI, 0.57-0.85; P basketball athletes. Conclusion: In basketball players, prophylactic programs may be effective in reducing the risk of general lower extremity injuries and ankle sprains, yet not ACL injuries. PMID:26502412

Child maltreatment constitutes a strong risk factor for violent delinquency in adolescence, with cumulative experiences of maltreatment creating increasingly greater risk. Our previous work demonstrated that a universal school-based violence prevention program could provide a protective impact for youth at risk for violent delinquency due to child maltreatment history. In this study we conducted a follow-up to determine if participation in a school-based violence prevention program in grade 9 continued to provide a buffering effect on engaging in acts of violent delinquency for maltreated youth, 2 years post-intervention. Secondary analyses were conducted using data from a cluster randomized controlled trial of a comprehensive school-based violence prevention program. Students (N=1,722; 52.8% female) from 20 schools participated in 21 75-min lessons in grade 9 health classes. Individual data (i.e., gender, child maltreatment experiences, and violent delinquency in grade 9) and school-level data (i.e., student perception of safety averaged across students in each school) were entered in a multilevel model to predict violent delinquency at the end of grade 11. Individual- and school-level factors predicting violent delinquency in grade 11 replicated previous findings from grade 9: being male, experiencing child maltreatment, being violent in grade 9, and attending a school with a lower perceived sense of safety among the entire student body increased violent delinquency. The cross-level interaction of individual maltreatment history and school-level intervention was also replicated: in non-intervention schools, youth with more maltreatment in their background were increasingly likely to engage in violent delinquency. The strength of this relationship was significantly attenuated in intervention schools. Follow-up findings are consistent with the buffering effect of the prevention program previously found post-intervention for the subsample of youth with maltreatment

Full Text Available Russia has been targeted with a series of terrorist attacks over the past several years, and there are a growing number of extremist groups operating throughout Russia’s society utilizing the Internet/social media to promote their narratives and objectives. Russia’s policy community has created institutional mechanisms and laws to address the challenge of violent extremism in the Internet/social media, and recognizes the importance of international cooperation toward these ends. This study, based on primary research conducted in Moscow in 2012, defines Russia’s assessment of domestic and international sources violent extremist threats; explains Moscow’s perspective on balancing democratic principles with the challenge of countering violent extremism in the Internet/social media; assesses existing capacities and impediments to further international collaboration with Russia in countering violent extremism in the Internet/social media spheres; defines specific initiatives that Russia, the United States, and other nations of the world community could advance to enhance international cooperation in countering violent extremism throughout the world cyber community.
Full Text Available Islamist violent extremist (IVE groups are frequently involved in civil conflicts. Indeed, some groups owe their origins to conflict, and tens of thousands of Islamists have chosen to participate in conflicts taking place in foreign countries in the past 35 years. Increasingly, IVE groups appear to have the capacity to influence the conflicts they are involved in, and are influenced in turn by their experiences. As a result, for those working on conflict resolution and post-conflict reconstruction, the involvement of IVE groups raises questions of whether traditional responses remain adequate. Drawing on three country case studies – Nigeria, Kenya and Iraq/Syria, this article examines the similarities and differences between IVE groups and other conflict actors, and what this means for development, state-building and peacebuilding responses.

Full Text Available The current global “war on terror” highlights a fundamental quandary for all liberal democracies seeking to counter the violent extremism of their own citizens while maintaining civic rights and freedoms. This challenge accompanies a transformation in international conflict from inter-state war and superpower rivalry, to homegrown terrorism, radicalization-to-violence, Internet propaganda, and targeting and recruitment of vulnerable persons. These new threats shift the battlefield, as traditionally defined, to the home front, as extremist violence is nurtured by and perpetrated within public spaces, such as schools, places of religious worship, civil society and the home. Today, violence emanates from within liberal democratic society and its extremist motivations bypass the very institutions that would otherwise support civic rights, freedoms and multiculturalism. As such, attempts to counter extremist violence must appeal to the political, social, cultural, religious and familial aspects of human behavior alongside a parallel shift in efforts to keep citizens safe within their own social spaces. In recent years, Canada has been introduced to home grown and lone individual terrorism with the cases of attack against armed forces personnel in Saint-Jean-sur-Richelieu and Ottawa in 2014. This article identifies the social dimensions of counter-terrorism in the Canadian context, a propitious case by which to evaluate different approaches to countering violent extremism. Canadian initiatives - simultaneously proliferating and in their infancy – raise a host of questions about counter-terrorism in liberal democratic countries. For example, why do individuals radicalize-to-violence in rights-based and multicultural societies? How and when can the liberal democratic state best temper the radicalization process in ways that are effective and procedurally just? What state-society balance works best to counter radicalized viewpoints? Who are the
Full Text Available This paper draws upon the findings of an evaluation of “More than a Game”, a sport-focused youth mentoring program in Melbourne, Australia that aimed to develop a community-based resilience model using team-based sports to address issues of identity, belonging, and cultural isolation amongst young Muslim men in order to counter forms of violent extremism. In this essay we focus specifically on whether the intense embodied encounters and emotions experienced in team sports can help break down barriers of cultural and religious difference between young people and facilitate experiences of resilience, mutual respect, trust, social inclusion and belonging. Whilst the project findings are directly relevant to the domain of countering violent extremism, they also contribute to a growing body of literature which considers the relationship between team-based sport, cross-cultural engagement and the development of social resilience, inclusion and belonging in other domains of youth engagement and community-building.

Criminal behaviour and violence may be the consequence of head injuries acquired during childhood and youth (gang fights, domestic violence, small blows to the head while driving, falls and so forth). In this study, a comparison was made of the school and head injury histories of violent and non-violent prisoners. It was found that the delinquent subjects in both groups had a history of academic difficulties. However, what differentiated the violent from the non-violent group was a history of having suffered head injuries that were never treated. Problems at school are not enough themselves to predict violent behaviour. A history of discrete neurological damage as a consequence to blows received to the head must also be present. The results suggest to the authors that the treatment of the cognitive, behavioural and emotional consequences of brain injury could be a measure for crime prevention. Measures both for prevention and rehabilitation are discussed.
This study deals with the relationship between school violence prevention training and teachers' perceived self-efficacy in handling violent events.

Disasters such as the 9/11 attacks, as well as major and unpredictable events, can cause extreme network overload. By "extreme overload" we mean, first, that the offered load at a link is significantly higher than the link's capacity, and second, that the average throughput per session is too low. Under such conditions, the network can suffer from a form of "livelock" in which even though links are fully utilized, most users cannot complete their transfers. The underlying reasons are that the network carries many retransmitted packets, and that it services flows that are finally aborted by users or applications. To prevent extreme network overload, we propose a router mechanism called Guardian. Guardian is a form of admission control module that is automatically activated when it detects the onset of extreme overload at a network link. Guardian's objective is to allow at least some sessions to complete, rejecting new TCP or UDP sessions that would probably not manage to acquire a minimum acceptable throughput. Guardian does not require signalling, and it can be implemented using standard techniques for session counting and caching. This paper describes on-going work. As such, we focus on the motivation for the proposed mechanism, and on Guardian's main design.

There is an implicit assumption of homogeneity across violent behaviors and offenders in the criminology literature. Arguing against this assumption, I draw on three distinct literatures [child abuse and neglect (CAN) and violence, violence and post-traumatic stress disorder (PTSD), and CAN and PTSD] to provide a rationale for an examination of varieties of violent behaviors. I use data from my prospective cohort design study of the long-term consequences of CAN to define three varieties of violent offenders using age of documented cases of CAN, onset of PTSD, and first violent arrest in a temporally correct manner [CAN → to violence, CAN → PTSD → violence (PTSD first), and CAN → violence → PTSD (violence first)], and a fourth variety, violence only. The results illustrate meaningful heterogeneity in violent behavior and different developmental patterns and characteristics. There are three major implications: First, programs and policies that target violence need to recognize the heterogeneity and move away from a "one-size-fits-all" approach. Second, violence prevention policies and programs that target abused and neglected children are warranted, given the prominent role of CAN in the backgrounds of these violent offenders. Third, criminologists and others interested in violence need to attend to the role of PTSD, which is present in about one fifth (21 percent) of these violent offenders, and not relegate the study of these offenders to the psychiatric and psychological literatures.

Full Text Available This article debates the justifications behind the practice of counter-radicalization and de-radicalization. It emphasizes the concepts as shrouded in confusion, and highlights that the practices continue to develop and expand despite claims of counter-productiveness, wholly subjective evaluation, and significant doubt around their premises. The aim of this article is to encourage a greater awareness of the potential costs to society of promoting policy with no rigorous basis of evidence. Focussing on both (rehabilitative prison counter-radicalization schemes and (preventative non-prison based de-radicalization, the discussion explores the evaluative methods that remain chaotic despite a growing need for ‘evidence-based’ public policy-making, examines the tenuous link between terrorism and ideology which upholds the principles behind attempts to combat radicalization, and then analyses the possible outcomes for society of relying on these schemes to minimize extremist violence. It concludes that taking the link between terrorism and ideology as causal is deeply flawed, and that by persisting with no systematic method of evaluation combating radicalization in these ways will continue to fail. Indeed, in prisons, they have been found to be distrusted, ineffective and even detrimental. Outside of prisons, where preventative counter-radicalization programmes exist, these will continue to divide societies among the lines where suspect communities are drawn. It takes the view that whilst we continue to elevate de-radicalization as a ‘useful tool’ in combating terrorism, we will also continue to associate certain people groups with terrorism and only add to grievances that exist in our societies.

If stock markets are complex, monetary policy and even financial regulation may be useless to prevent bubbles and crashes. Here, we suggest the use of robot traders as an anti-bubble decoy. To make our case, we put forward a new stochastic cellular automata model that generates an emergent stock price dynamics as a result of the interaction between traders. After introducing socially integrated robot traders, the stock price dynamics can be controlled, so as to make the market more Gaussian.

Lower extremity injuries are common in basketball, yet it is unclear how prophylactic interventions affect lower extremity injury incidence rates. To analyze the effectiveness of current lower extremity injury prevention programs in basketball athletes, focusing on injury rates of (1) general lower extremity injuries, (2) ankle sprains, and (3) anterior cruciate ligament (ACL) tears. PubMed, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Register of Controlled Trials were searched in January 2015. Studies were included if they were randomized controlled or prospective cohort trials, contained a population of competitive basketball athletes, and reported lower extremity injury incidence rates specific to basketball players. In total, 426 individual studies were identified. Of these, 9 met the inclusion criteria. One other study was found during a hand search of the literature, resulting in 10 total studies included in this meta-analysis. Systematic review and meta-analysis. Level 2. Details of the intervention (eg, neuromuscular vs external support), size of control and intervention groups, and number of injuries in each group were extracted from each study. Injury data were classified into 3 groups based on the anatomic diagnosis reported (general lower extremity injury, ankle sprain, ACL rupture). Meta-analyses were performed independently for each injury classification. Results indicate that prophylactic programs significantly reduced the incidence of general lower extremity injuries (odds ratio [OR], 0.69; 95% CI, 0.57-0.85; P ankle sprains (OR, 0.45; 95% CI, 0.29-0.69; P basketball athletes. In basketball players, prophylactic programs may be effective in reducing the risk of general lower extremity injuries and ankle sprains, yet not ACL injuries. © 2015 The Author(s).
Full Text Available Recently, more than 150 Canadians have joined the Islamic State (IS in the Middle East, causing alarm among both Canadian policy makers and the general citizenry. One of the most salient questions related to this development pertains to the factors that drove these young people to extremism. Most experts posit that extremism is caused by multiple factors embedded in our social, economic, geopolitical, and cultural processes. However, evidence to support such claims is still poor as limited primary research has been done in Canada to understand, explain, and identify radicalism’s causes, its main drivers, and its global-local linkages. Due to their emphasis on policy and federal law enforcement, studies of radicalism in Canada have proven inadequate in outlining a comprehensive understanding of the psycho-social conditions that might be associated with the radicalization process. Considering the above gaps, this research draws upon three studies in order to map the perceptions of the leadership of Islamic community-based organizations and university-based student organizations with regards to issues related to social conflict, terrorism, and counter-terrorism in Canada. The objective of this study is to both document the existence of radicalism and to determine the role of critical social issues that may potentially contribute to this phenomenon. In addition, this paper will hopefully elaborate on the results of a multi-level (macro, meso, and micro analysis of the social factors which act as key drivers of radicalism through the use of qualitative methods and the aid of social conflict and social-psychological theoretical lenses. Finally, the study concludes by exploring the Canadian national counter-terrorism (CT strategy’s effectiveness in countering radicalization.

A characteristic feature of complex systems in general is a tight coupling between their constituent parts. In complex socio-economic systems this kind of behavior leads to self-organization, which may be both desirable (e.g. social cooperation) and undesirable (e.g. mass panic, financial "bubbles" or "crashes"). Abundance of the empirical data as well as general insights into the trading behavior enables the creation of simple agent-based models reproducing sophisticated statistical features of the financial markets. In this contribution we consider a possibility to prevent self-organized extreme events in financial market modeling its behavior using agent-based herding model, which reproduces main stylized facts of the financial markets. We show that introduction of agents with predefined fundamentalist trading behavior helps to significantly reduce the probability of the extreme price fluctuations events. We also investigate random trading, which was previously found to be promising extreme event prevention strategy, and find that its impact on the market has to be considered among other opportunities to stabilize the markets.

Psychiatric patients are at high risk of becoming victim of a violent crime compared to the general population. Although most research has focused on patients with severe mental illness, depressed patients have been demonstrated to be prone to victimization as well. Victimization is associated with more severe symptomatology, decreased quality of life, and high risk of revictimization. Hence, there is a strong need for interventions that focus on preventing violent revictimization. Since emotion dysregulation is associated with both victimization and depression, we developed an internet-based Emotion Regulation Training (iERT) to reduce revictimization in depressed patients. This study aims to evaluate the clinical and cost-effectiveness of iERT added to Treatment As Usual (TAU) in reducing incidents of violent revictimization among depressed patients with a recent history of victimization. Furthermore, this study aims to examine secondary clinical outcomes, and moderators and mediators that may be associated with treatment outcomes. In a multicenter randomized controlled trial with parallel group design, patients with a major depressive disorder and a history of violent victimization over the past three years (N = 200) will be allocated to either TAU + iERT (N = 100) or TAU only (N = 100), based on computer-generated stratified block randomization. Assessments will take place at baseline, 8 weeks, 14 weeks, and 6 months after start of treatment, and 12, 24, and 36 months after baseline. The primary outcome measure is the total number of violent victimization incidents at 12 months after baseline, measured with the Safety Monitor: an adequate self-report questionnaire that assesses victimization over the preceding 12 months. Secondary outcome measures and mediators include emotion dysregulation and depressive symptomatology. An economic evaluation with the societal perspective will be performed alongside the trial. This study is the first to

Full Text Available The paper reveals the inefficiency problem of preventive measures controlling students’ intolerant and extremist behavior in higher educational institutions. According to the author, such trends in students’ society, as well as the rising phenomenon of nationalistic religious identity inevitably leading to interpersonal tensions, are caused in the last decades by the degrading prestige of higher education, growing pragmatism and formality of its achievement and key value depreciation in higher educational institutions. To improve the existing situation, it is necessary to revive the main functions of higher educational establishments –the intellectual and professional elite formation, cherishing the humanity values, social responsibility and active civil position; on the other hand, it is vitally important to create the system of prevention and correction of such trends as intolerance and extremism. However, the above goals are aggravated by the number of other problems listed in the paper.The method of developing the system of complex prevention of the mentioned negative phenomena is proposed with the reference to higher educational institutions; the specific stages of the given method, the technologies and organizational forms being outlined; the practical application and outcome in Tyumen State University being discussed. The research findings can be interesting for people responsible for preventive measures in higher educational instinutionms.

Psychological studies invariably find a positive relationship between violent video game play and aggression. However, these studies cannot account for either aggressive effects of alternative activities video game playing substitutes for or the possible selection of relatively violent people into playing violent video games. That is, they lack external validity. We investigate the relationship between the prevalence of violent video games and violent crimes. Our results are consistent with t...

Young people are overrepresented as both victims and perpetrators of violence. Indeed, some commentators have suggested that recent cohorts of youth have been composed of "superpredators" who have little regard for human life. The evidence, however, suggests that other factors are responsible for recent increases in youth gun violence. This article analyzes the extent and causes of youth violence in the United States, paying particular attention to the late 1980s and early 1990s, when rates of homicide and robbery committed by youth rose to extremely high levels. Examination of trends for these crimes shows that: The increase in violence in the United States during the late 1980s and early 1990s was due primarily to an increase in violent acts committed by people under age 20. Similarly, dramatic declines in homicide and robbery in recent years are attributable primarily to a decline in youth violence. The increase in youth homicide was predominantly due to a significant increase in the use of handguns, which converted ordinary teenage fights and other violent encounters into homicides. Several other interrelated factors also fueled the rise in youth violence, including the rise of illegal drug markets, particularly for crack cocaine, the recruitment of youth into those markets, and an increase in gun carrying among young people. The author points out that youth violence diminished as the crack markets shrank, law enforcement increased efforts to control youth access to guns, youth gun carrying declined, and the robust economy provided legitimate jobs for young people.

Background This study aims to describe the specific characteristics of completed suicides by violent methods and non-violent methods in rural Chinese population, and to explore the related factors for corresponding methods. Methods Data of this study came from investigation of 199 completed suicide cases and their paired controls of rural areas in three different counties in Shandong, China, by interviewing one informant of each subject using the method of Psychological Autopsy (PA). Results There were 78 (39.2%) suicides with violent methods and 121 (60.8%) suicides with non-violent methods. Ingesting pesticides, as a non-violent method, appeared to be the most common suicide method (103, 51.8%). Hanging (73 cases, 36.7%) and drowning (5 cases, 2.5%) were the only violent methods observed. Storage of pesticides at home and higher suicide intent score were significantly associated with choice of violent methods while committing suicide. Risk factors related to suicide death included negative life events and hopelessness. Conclusions Suicide with violent methods has different factors from suicide with non-violent methods. Suicide methods should be considered in suicide prevention and intervention strategies. PMID:25111835
Full Text Available Background An increase in self-destructive and aggressive behaviours in adolescents has been observed in recent years. The present study focused on self-perception of adolescent girls who show different types of extreme destructive behaviours (suicidal or violent. The main aim of the study was to identify personality predictors of suicidal and violent behaviour in adolescent girls. Participants and procedure The study involved 163 female participants aged 13-17 years, including 44 suicide attempters (without extreme aggressive behaviour towards others, 46 girls using violence against others (without extreme self-destructive behaviour and 77 girls exhibiting no destructive behaviour. The following research methods were applied: the Adjective Checklist (ACL (versions “What am I like?” and “What would I like to be?”, and the Sentence Completion Test. Results The girls showing extreme destructive behaviour, particularly self-destructive behaviour, were found to have a more negative self-image, a lower level of consistency of the self-image, lower self-esteem and a higher level of inner conflict than the control group. Stepwise discriminant analysis was used to determine predictors of extreme self-destructive or aggressive behaviours. Escalated inner conflicts within the attitude towards oneself appear to be the most important predictor of suicidal behaviour in adolescent girls, whereas self-perception based on strength seems to be the most significant predictor of violent behaviour in adolescent girls. Conclusions The research showed that destructive behaviour among adolescents is a multidimensional phenomenon. The statistical model presented in the study has been proved to have a high value. The results can help in successful prevention and therapy of destructive behaviours in adolescents.

The leakage of large plastic litter (macroplastics) into the ocean is a major environmental problem. A significant fraction of this leakage originates from coastal cities, particularly during extreme rainfall events. As coastal cities continue to grow, finding ways to reduce this macroplastic leakage is extremely pertinent. Here, we explore why and how coastal cities can reduce macroplastic leakages during extreme rainfall events. Using nine global cities as a basis, we establish that while cities actively create policies that reduce plastic leakages, more needs to be done. Nonetheless, these policies are economically, socially and environmentally cobeneficial to the city environment. While the lack of political engagement and economic concerns limit these policies, lacking social motivation and engagement is the largest limitation towards implementing policy. We recommend cities to incentivize citizen and municipal engagement with responsible usage of plastics, cleaning the environment and preparing for future extreme rainfall events.

We present a computational approach to radical rhetoric that leverages the co-expression of rhetoric and action features in discourse to identify violent intent. The approach combines text mining and machine learning techniques with insights from Frame Analysis and theories that explain the emergence of violence in terms of moral disengagement, the violation of sacred values and social isolation in order to build computational models that identify messages from terrorist sources and estimate their proximity to an attack. We discuss a specific application of this approach to a body of documents from and about radical and terrorist groups in the Middle East and present the results achieved.
Full Text Available Female violent offending is an understudied topic in Spanish-speaking countries. This review explores themajor research findings accumulated internationally over the last decade (2003-2013 about women'sviolence and crimes. The focus of the review is the intimate partner violence (IPV and sexual violencecommitted by females, the psychopathy and violence risk assessment, and the treatment and recidivism ofthese female offenders. Although the female offender topic is too wide to review all crime typologies (childphysical abuse is not included, for example the review indicates that: there are legal and police biases inthe treatment of women offenders; women can commit the same IPV and share the motivations of maleoffenders; sexual violence has a low prevalence, but there are many limitations in this research topic;predicting the risk of non-specific violence is feasible with the available tools; psychopathy is less prevalentamong adult female offenders, although there are fewer differences with male offenders among adolescentsamples; research about treatments is very limited and there are not effectiveness evidences; and last,recidivism rates for violent crimes are very low (in cases where information is available. Main implicationsand research lines are discussed.
Full Text Available Numerous international research has identified that direct or indirect exposure to violent victimization in a familial context during childhood is a risk factor for violent criminal behavior of victimized children in adulthood. Studies of violent victimization of children in Serbia are rare, and are mostly directed at determining the prevalence, the main characteristics of or the immediate physical, psychological and behavioral consequences of victimization. Empirical analysis of the criminological consequences of early violent victimization in adulthood are an exception in scientific studies in Serbia. The aim of the paper is to present the results of research into the influence of early violent victimization on violent crime of adult men and women. After the introduction a brief overview of the worldwide research confirming the correlation between the experience of violent victimization and subsequent violent behavior is given. The results of the research conducted by the author will then be discussed. The results illustrate the possibility of predicting violent criminal behavior in adulthood based on indicators of direct and indirect victimization in childhood.

To study the incidence, diagnosis, prevention and treatment of peripherally inserted central catheter (PICC)-related upper extremity deep vein thrombosis (DVT) in breast cancer patients using a PICC catheter for chemotherapy. The data of the incidence, diagnosis and treatment of PICC-related upper extremity DVT in 187 breast cancer patients using a PICC catheter for chemotherapy, from August 2009 to July 2011 were retrospectively analyzed. In total 188 PICC were inserted between August 2009 and July 2011 and followed up for a total of 14 399 catheter-days (median placement, 76.6 days; range, 1 to 170 days). Four (2.1%) of 188 PICC were removed as a result of PICC-related upper extremity DVT in 14 to 112 catheter-days, at a rate of 0.28/1000 catheter-days. The use of PICCs in breast cancer patients for chemotherapy is safe and effective. However, some patients may develop catheter-related upper extremity DVT. In order to minimize complications, we should pay attention to its early symptoms and signs, as well as the timely removal of the catheter and appropriate anti-coagulant treatment. © 2012 Wiley Publishing Asia Pty Ltd.
Full Text Available This article discusses how adolescents become violent from the perspective of human development, in which the process of formation of the child and the youth depends on diverse biological, psychological e social variables that constitute the context of life of these individuals. The ecological perspective of human development opposes simple cause-effect relations between antisocial adversities and behaviors and believes that factors such as gender, temperament, cognitive ability, age, family, social environment and culture combine in a complex way influencing the behavior of the child and the adolescent. Some conclusions point to the fact that violence in adolescence usually starts from a combination of early difficulties in relationships associated with a combination of temperamental difficulties. It is concluded that the young seem to be as bad as the social environment surrounding them.

Objective: To discuss the prevention and nursing care of the perioperative complications occurred in interventional therapy for arteriosclerosis obliterans of lower extremity. Methods: During the period of July 2006 to June 2009, interventional treatment for the arteriosclerosis obliterans of lower extremity was performed in 380 cases. The clinical data and complications were reviewed and analyzed, and the prevention and nursing care of the complications were summarized. Results: Complications occurred in 41 cases. During the surgery, vascular rupture or arterial dissection occurred in 5 cases, hypoglycemia reaction in 3 cases and elevation of blood pressure in 2 cases. The complications,which occurred after the treatment,included acute arterial thrombosis (n=3), deep vein thrombosis (n=2), bleeding of different tissues or organs (n=17), acute myocardial infarction (n=2), pseudoaneurysm (n=2), excessive lower limb perfusion syndrome (n=4) and compression sores (n=1). Conclusion: Detailed information of medical history, careful observation of clinical condition, intensive care of patient, adequate preparation of medical materials, seriously handing over the duty to the next shift and taking one's turn on duty, etc. are all the effective measures to prevent and to reduce the occurrence of complications.

We aimed to compare the incidence of skin lesions and central line-associated bloodstream infection (CLABSI) among extremely preterm infants when using 0.5% CHG-70% alc and 0.2% CHG-acetate. Retrospective pre-post comparison cohort study. All electronic patient records of extremely preterm infants born between January 2011-March 2013 ('0.5% CHG-70% alc' cohort) and April 2013-October 2015 ('0.2% CHG-acetate' cohort) were reviewed. The incidence of skin lesions and CLABSI. Skin lesions were defined as the presence of erythema, blisters, excoriation, oedema or induration. CLABSI was defined according to the definition of the US Centers for Disease Control and Prevention. The incidence of skin lesions was 22% (95% CI 11% to 37%) in the '0.5% CHG-70% alc' cohort (n=41) and 5% (95% CI 1% to 15%; p=0.02) in the '0.2% CHG-acetate' cohort (n=41). The incidence of CLABSI was the same in both groups (28%; 95% CI 14% to 46% in '0.5% CHG-70% alc' vs 27%; 95% CI 14% to 44% in '0.2% CHG-acetate'; p=0.98). Using 0.2% CHG-acetate as skin disinfectant in extremely preterm infants resulted in statistically significant reduction of skin lesions, without increasing the risk of CLABSI as compared with 0.5% CHG-70% alc. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The formation of a saturated body of coal-water mixture is due to the actions of multiple controlling factors of water source, coal characteristics, potential energy and time. Coal-water burst disaster is characterized by paroxysm, huge energy, short duration, strong explosive force and causing severe damages. Very often it takes place only under special background conditions. In extremely inclined coal seam districts, because the working faces are generally arranged under water-prevention coal pillars, the mining inbreak heights are too near the location of the body of coal-water mixture. Hence the mining activity may induce the occurrence of coal-water burst disaster. Based on the analysis of the disaster mechanism, some effective preventive measures for coal-water burst disaster in coal mines are put forward. 3 refs., 1 fig.

The aim of this paper is to revisit the controversial issue of the association of violent video games and aggressive behaviour. Several lines of evidence suggest that there is a link between exposure to violent video games and aggressive behaviour. However, methodological shortcomings of research conducted so far make several interpretations of this relationship possible. Thus, aggressive behaviour may be a consequence of playing violent video games, an expression of hostile traits that existed before exposure to these games, and/or it may be a result of several possible combinations of these and other factors. Mental health professionals need to be aware of these potentially negative effects of violent video games when assessing patients who present with aggression. There is a need for prospective, long-term studies similar to those evaluating the effects of television and film violence on children and adolescents.

Full Text Available I propose a dual conceptualization of violent crime. Since violent crime is both violence and crime, theories of aggression and deviance are required to understand it. I argue that both harm-doing and rule breaking are instrumental behaviors and that a bounded rational choice approach can account for both behaviors. However, while some of the causes of harm-doing and deviance (and violent and nonviolent crime are the same, some are different. Theories of crime and deviance cannot explain why one only observes individual and group differences in violent crime and theories of aggression and violence cannot explain why one observes differences in all types of crimes. Such theories are “barking up the wrong tree.”

This letter reviews the scientific literature on whether and how environmental changes affect the risk of violent conflict. The available evidence from qualitative case studies indicates that environmental stress can contribute to violent conflict in some specific cases. Results from quantitative large-N studies, however, strongly suggest that we should be careful in drawing general conclusions. Those large-N studies that we regard as the most sophisticated ones obtain results that are not robust to alternative model specifications and, thus, have been debated. This suggests that environmental changes may, under specific circumstances, increase the risk of violent conflict, but not necessarily in a systematic way and unconditionally. Hence there is, to date, no scientific consensus on the impact of environmental changes on violent conflict. This letter also highlights the most important challenges for further research on the subject. One of the key issues is that the effects of environmental changes on violent conflict are likely to be contingent on a set of economic and political conditions that determine adaptation capacity. In the authors' view, the most important indirect effects are likely to lead from environmental changes via economic performance and migration to violent conflict.

This letter reviews the scientific literature on whether and how environmental changes affect the risk of violent conflict. The available evidence from qualitative case studies indicates that environmental stress can contribute to violent conflict in some specific cases. Results from quantitative large-N studies, however, strongly suggest that we should be careful in drawing general conclusions.

Full Text Available Research into violent extremism is lacking integrated theoretical frameworks explaining individual involvement in politically or religiously motivated violence, resulting in a poor understanding of causal mechanisms. Building on situational action theory, the current study moves beyond the dominant risk factor approach and proposes an integrated model for the explanation of political/religious violence, distinguishing between direct mechanisms and “causes of the causes.” The model integrates mechanisms from different but complementary traditions. Following previous work, this study focusses on the causes of the causes influencing direct key mechanisms, violent extremist propensity, and exposure to violent extremist moral settings that explain political/religious violence. The theoretical model is tested using structural equation modelling. The analyses are based on a web survey (N = 6,020 among adolescents and young adults in Belgium. Results show that violent extremist propensity and exposure to violent extremist moral settings have direct effects on the likelihood of political/religious violence. These direct mechanisms are in turn determined by a series of exogenous factors: perceived injustice and poor social integration. The relationship between perceived injustice and poor social integration and political/religious violence is further mediated by perceived alienation, perceived procedural justice, and religious authoritarianism. The implications of these findings are discussed.

The burden of disabling musculoskeletal pain and injuries (musculoskeletal disorders, MSDs) arising from work-related causes in many workplaces remains substantial. There is little consensus on the most appropriate interventions for MSDs. Our objective was to update a systematic review of workplace-based interventions for preventing and managing upper extremity MSD (UEMSD). We followed a systematic review process developed by the Institute for Work & Health and an adapted best evidence synthesis. 6 electronic databases were searched (January 2008 until April 2013 inclusive) yielding 9909 non-duplicate references. 26 high-quality and medium-quality studies relevant to our research question were combined with 35 from the original review to synthesise the evidence on 30 different intervention categories. There was strong evidence for one intervention category, resistance training, leading to the recommendation: Implementing a workplace-based resistance training exercise programme can help prevent and manage UEMSD and symptoms. The synthesis also revealed moderate evidence for stretching programmes, mouse use feedback and forearm supports in preventing UEMSD or symptoms. There was also moderate evidence for no benefit for EMG biofeedback, job stress management training, and office workstation adjustment for UEMSD and symptoms. Messages are proposed for both these and other intervention categories. PMID:26552695

The oropharyngeal administration of mother's milk-placing drops of milk onto the infant's oral mucosa-may serve as a preventative strategy against necrotizing enterocolitis (NEC) for extremely low-birth-weight (ELBW: birth weight pneumonia, an earlier attainment of full enteral feeds, enhanced maturation of oral feeding skills, improved growth, and enhanced breast-feeding outcomes. While more research is needed to definitively establish safety and efficacy of this intervention, this article will examine biological plausibility and will describe the theoretical mechanisms of protection against NEC for ELBW infants who receive this intervention. Nurses play a key role in advancing the science and practice of this intervention. Future directions for research and implications for nursing practice will also be presented.
Full Text Available The British government’s controversial counter-terrorism strategies and policies have come under fierce opposition with critics arguing it has not actually prevented extremism but has manifested itself into a political and ideological campaign that unfairly targets the Muslim community. Moreover, such strategies have marginalised the Muslim community in the UK from wider civic society and created an atmosphere of hate and anger. The Prime Minister of Great Britain, David Cameron in 2010, spoke at a conference in Munich about security, radicalisation, and multi-culturalism, sparking a debate about how the UK monitors and deals with extremism. Blaming the doctrine of ‘state-multiculturalism’ the British coalition government argued for a more ‘active muscular liberalism’ which would identify the root causes of extremist ideologies. Moreover, this paranoia and hysteria has led to a social, political, moral and theological debate about Islamism, Muslims, and terrorism which is fuelled by the way Britain is portrayed across the world as a country where extremist organisations employ tactics of persuasion, indoctrination, radicalisation and the promotion of religious intolerance.

While culture has a significant effect on the appropriate interpretation of textual data, the incorporation of cultural considerations into data transformations has not been systematic. Recognizing that the successful prevention of terrorist activities could hinge on the knowledge of the subcultures, Anthropologist and DHS intern Faith Nibbs has been addressing the need to incorporate cultural knowledge into the analytical process. In this Brown Bag she will present how cultural ideology is being used to understand how the rhetoric of group leaders influences the likelihood of their constituents to engage in violent or radicalized behavior, and how violent intent modeling can benefit from understanding that process.

The seasonal variations of individual violent crimes, i.e. sexual offenses and aggravated assaults, and non-violent offenses, i.e. burglary, in Israel, the USA, Denmark and New South Wales, Australia, representing four continents, were analyzed. Seasonal variations in the opening dates of wars were similarly analyzed. In northern hemisphere countries, although non-violent offenses are distributed equally throughout the year, individual violent crimes and collective acts of hostility are characterized by an annual rhythm of incidence, with a peak in the months of July-August and a nadir in December-February. Inverse rhythms were obtained in southern hemisphere countries. These rhythms were found to be correlated in a statistically significant manner with the duration of the daily photoperiod. The existence of similar patterns of annual variations in violent crimes and in the opening dates of wars indicate similarities between individual and collective aggressiveness with respect to the underlying mechanisms and probably also to the means of their prevention.

Young drug users are found to be increasingly involved in criminal justice issues. This exploratory and descriptive study aims to analyze the criminal behaviors among young Chinese drug users through a mixed methods research design. Quantitative analysis indicates that young drug users with and without a history of criminality show significant differences in terms of several features. Male drug users, particularly, those who are older, with religious beliefs, and initiated into drug use at younger age were most likely to commit crimes. Among drug users with criminal experiences, those who committed crimes prior to drug initiation have a greater likelihood of committing violent crimes. Furthermore, young drug users with severe depression are more likely to commit crimes, especially violent ones. Qualitative analysis further illustrates that young male drug users often get involved in criminal conduct of the youth gang nature with propensity for engaging in violent crimes as compared to their female counterparts who are more likely to turn into drug dealers and traffickers, in addition to engaging in larceny. The research findings are consistent with developmental theories and "victim to offender cycle". Integrated mental health and substance use services are suggested for crime prevention among young Chinese drug users.

Objective Homicide and suicide are two important and potentially preventable causes of maternal injury. We analyzed data from the National Violent Death Reporting System to estimate the rates of pregnancy-associated homicide and suicide in a multi-state sample, to compare these rates with other causes of maternal mortality, and to describe victims’ demographic characteristics. Methods We analyzed data from female victims of reproductive age from 2003–2007. We identified pregnancy-associated violent deaths as deaths due to homicide or suicide during pregnancy or within the first year postpartum. We calculated the rates of pregnancy-associated homicide and suicide as the number of deaths per 100,000 live births in the sample population. We used descriptive statistics to report victims’ demographic characteristics and prevalence of intimate partner violence (IPV). Results There were 94 counts of pregnancy-associated suicide and 139 counts of pregnancy-associated homicide, yielding pregnancy-associated suicide and homicide rates of 2.0 and 2.9 deaths/100,000 live births, respectively. Victims of pregnancy-associated suicide were significantly more likely to be older and of Caucasian or American Indian descent as compared to all live births in NVDRS states. Pregnancy-associated homicide victims were significantly more likely to be at the extremes of the age range and African American. 54.3% of pregnancy-associated suicides involved intimate partner conflict that appeared to contribute to the suicide. 45.3% of pregnancy-associated homicides were IPV-associated. Conclusions Our results indicate that pregnancy-associated homicide and suicide are important contributors to maternal mortality and confirm the need to evaluate the relationships between socio demographic disparities and IPV with pregnancy-associated violent death.

Full Text Available This article presents a case study of the recently conceived and ongoing counter-extremism campaign, Voices Against Extremism, a campaign designed and implemented by university students from Vancouver, Canada. Through a multifaceted approach that includes extensive use of social media, academic research, and grassroots community activities and involvement, Voices Against Extremism operates under the mission statement of countering and preventing violent extremism and radicalization through the humanization of minority groups and through the education and engagement of the silent majority. This article examines the effectiveness of this campaign as a proactive counter-radicalization strategy by outlining its specific components and activities. Based on the results of this campaign, suggestions are then offered regarding specific counter-extremism and counter-radicalizations policies that may be adopted by law enforcement, policymakers – or any other organizations concerned with countering and preventing radicalization and violent extremism – with a specific focus on the potential benefits of proactive and long-term social and community engagement.

Shock-absorbing and biomechanic shoe orthoses are frequently used in the prevention and treatment of back and lower extremity problems. One review concludes that the former is clinically effective in relation to prevention, whereas the latter has been tested in only 1 randomized clinical trial, concluding that stress fractures could be prevented. To investigate if biomechanic shoe orthoses can prevent problems in the back and lower extremities and if reducing the number of days off-duty because of back or lower extremity problems is possible. Prospective, randomized, controlled intervention trial. One female and 145 male military conscripts (aged 18 to 24 years), representing 25% of all new conscripts in a Danish regiment. Health data were collected by questionnaires at initiation of the study and 3 months later. Custom-made biomechanic shoe orthoses to be worn in military boots were provided to all in the study group during the 3-month intervention period. No intervention was provided for the control group. Differences between the 2 groups were tested with the chi-square test, and statistical significance was accepted at P biomechanic shoe orthoses. However, because care-seeking for lower extremity problems is rare, using this method of prevention in military conscripts would be too costly. We also noted that the choice of statistical approach determined the outcome.

Alcohol is more likely than any other drug to be involved in substance-related violence. In 2000 violence-related and self-directed injuries accounted for an estimated $37 billion and $33 billion in productivity losses and medical treatment, respectively. A review of emergency department data revealed violence and clinically identified trauma-related injuries have the strongest correlation among alcohol-dependent injuries. At the environmental level there is a relationship between alcohol outlet density and violent crime. A limited number of studies have examined the relationship between alcohol outlet type and the components of violent crime. The aim of this study is to examine the relationship between the aggregate components of violent crime and alcohol outlet density by type of outlet. For this study we used Washington, D.C. census tract data from the 2000 census to examine neighborhood characteristics. Alcohol outlet, violent crime, and population-level data for Washington, D.C. were drawn from various official yetpublicly available sources. We developed an analytic database to examine the relationship between alcohol outlet category and four types of violent crime. After estimating spatial correlation and determining spatial dependence, we used a negative binomial regression analysis to assess the alcohol availability-violent crime association, while controlling for structural correlates of violence. Independent of alternative structural correlates of violent crime, including the prevalence of weapons and illicit drugs, community-level alcohol outlet density is significantly associated with assaultive violence. Outlets were significantly related to robbery, assault, and sexual offenses. In addition, the relationship among on-premise and off-premise outlets varied across violent crime categories. In Washington, D.C., alcohol outlet density is significantly associated with the violent crimes. The science regarding alcohol outlet density and alcohol

Full Text Available Este trabalho tem como objetivo identificar a construção de três tipos de representações sociais: as da violência doméstica, as dos agressores e as que os adolescentes, agredidos na infância têm de si mesmos. Buscaram-se temas que norteassem uma proposta de prevenção da violência doméstica pesquisando-os em 90 adolescentes da cidade de Campinas, São Paulo. O ponto de partida foi analisar a problemática que envolve o fenômeno da violência doméstica e sua relação com os comportamentos socialmente inadequados (rebeldia, condutas marginais ou violentas e seu efeito na auto-imagem dos adolescentes. A dinâmica de coleta de dados visou, através da entrevista inicial, dos questionários e das fichas de registro do Crami - Centro Regional de Registro e Atenção aos Maus Tratos na Infância, Campinas - a identificar a notificação de violências físicas sofridas na infância e a investigar os discursos dos atores sociais, numa perspectiva dialógica, como a principal fonte de informação e expressão oral e escrita. A análise realizada foi de natureza qualitativa-quantitativa. A primeira, destina-se ao exame dos conteúdos dos discursos, através da análise semântica e léxica.

As global sea levels and natural resource demands rise, people around the world are increasingly protesting environmental threats to their lives and livelihoods. What are the conditions under which these peaceful environmental protests are violently repressed? This paper uses the random forest algorithm to conduct an event analysis of grassroots environmental protests around the world. Utilizing a database of 175 grassroots environmental protests, we found that: (1) a large proportion (37 %) of the protests involved violent repression; (2) most of the violence (56 %) was directed against marginalized groups; and (3) violence was geographically concentrated the global south in Latin America and Asia. The primary predictors of violence were political empowerment, GDP per capita, industry type, the presence of marginalized groups, and geographic region. Our analysis reveals a complex relationship between governance, resource extraction, and international funding that often resulted in human rights violations against marginalized groups.
In a Norwegian follow-up study of former adolescent psychiatric in-patients 222 patients who had committed violent crimes were compared to 287 patients who had committed non-violent crimes only. There were numerous significant differences between the criminal careers of violent and non-violent criminals. Individuals with a history of violent criminality only were uncommon and uncharacteristic of violent criminals in general. Regression analyses identified several strong and independent correlates of violent criminality. The study supported a division of antisocial behavior into violent and non-violent sub-groups, thus paralleling a concept of overt and covert pathways to delinquent behavior. The overt pathway seemed to be imbedded in the covert pathway.

Antipsychotics and mood stabilisers are prescribed widely to patients with psychiatric disorders worldwide. Despite clear evidence for their efficacy in relapse prevention and symptom relief, their effect on some adverse outcomes, including the perpetration of violent crime, is unclear. We aimed to establish the effect of antipsychotics and mood stabilisers on the rate of violent crime committed by patients with psychiatric disorders in Sweden. We used linked Swedish national registers to study 82,647 patients who were prescribed antipsychotics or mood stabilisers, their psychiatric diagnoses, and subsequent criminal convictions in 2006-09. We did within-individual analyses to compare the rate of violent criminality during the time that patients were prescribed these medications versus the rate for the same patients while they were not receiving the drugs to adjust for all confounders that remained constant within each participant during follow-up. The primary outcome was the occurrence of violent crime, according to Sweden's national crime register. In 2006-09, 40,937 men in Sweden were prescribed antipsychotics or mood stabilisers, of whom 2657 (6·5%) were convicted of a violent crime during the study period. In the same period, 41,710 women were prescribed these drugs, of whom 604 (1·4 %) had convictions for violent crime. Compared with periods when participants were not on medication, violent crime fell by 45% in patients receiving antipsychotics (hazard ratio [HR] 0·55, 95% CI 0·47-0·64) and by 24% in patients prescribed mood stabilisers (0·76, 0·62-0·93). However, we identified potentially important differences by diagnosis-mood stabilisers were associated with a reduced rate of violent crime only in patients with bipolar disorder. The rate of violence reduction for antipsychotics remained between 22% and 29% in sensitivity analyses that used different outcomes (any crime, drug-related crime, less severe crime, and violent arrest), and was stronger in

Violent forms of discipline in schools continue to be widespread across the globe despite their damaging effects. Since little is known about factors influencing the extent of violence applied by teachers, this study aimed to investigate the influence of teachers' stress, work satisfaction, and personal characteristics on their disciplining style. Using structural equation modeling, associations between violent discipline, burnout symptoms, and job perceptions (pressure and difficulties in class) reported by 222 teachers from 11 secondary schools in Tanzania in 2015 were analyzed. Results indicated a direct association between perceived stress and emotional violent discipline (β=.18, pstress also mediated the association between job perceptions and both forms of violent disciplining. The model showed good model fit (χ 2 [44, n=222]=67.47 (p=.013), CFI=.94, TLI=.91, IFI=.94, RMSEA=.049 [90%-CI=.02-.07, PCLOSE=.50], SRMR=.06). Our findings suggest that teachers' personal perceptions of their work as well as their stress burden play a role in their disciplining styles. Our findings underline the importance of integrating topics, such as stress and coping as well as positive, nonviolent discipline measures into the regular teacher's training and in addition to develop and evaluate school-based preventative interventions for teachers.

Ferguson's comprehensive meta-analysis provides convincing data that violent video games have almost no effect on children's aggression. Although this finding is unlikely to bring unity to a divided field, Ferguson's article (2015, this issue) provides important rules that should aid all researchers. First, we need to be more accepting of results that are inconsistent with our own theories. Second, extraneous variables are often responsible for the relations previous studies have found between violent media and aggression. Third, we should avoid using unstandardized assessments of important variables whenever possible. Finally, caution is warranted when generalizing laboratory research findings to severe acts of violent in the "real world." It is hoped that, by accepting these basic rules, researchers and others will adopt less extreme positions concerning the effects of violent video games. © The Author(s) 2015.

Recovery strategies are often used with the intention of preventing or minimising muscle soreness after exercise. Whole-body cryotherapy, which involves a single or repeated exposure(s) to extremely cold dry air (below -100 °C) in a specialised chamber or cabin for two to four minutes per exposure, is currently being advocated as an effective intervention to reduce muscle soreness after exercise. To assess the effects (benefits and harms) of whole-body cryotherapy (extreme cold air exposure) for preventing and treating muscle soreness after exercise in adults. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, the British Nursing Index and the Physiotherapy Evidence Database. We also searched the reference lists of articles, trial registers and conference proceedings, handsearched journals and contacted experts.The searches were run in August 2015. We aimed to include randomised and quasi-randomised trials that compared the use of whole-body cryotherapy (WBC) versus a passive or control intervention (rest, no treatment or placebo treatment) or active interventions including cold or contrast water immersion, active recovery and infrared therapy for preventing or treating muscle soreness after exercise in adults. We also aimed to include randomised trials that compared different durations or dosages of WBC. Our prespecified primary outcomes were muscle soreness, subjective recovery (e.g. tiredness, well-being) and adverse effects. Two review authors independently screened search results, selected studies, assessed risk of bias and extracted and cross-checked data. Where appropriate, we pooled results of comparable trials. The random-effects model was used for pooling where there was substantial heterogeneity. We assessed the quality of the evidence using GRADE. Four laboratory-based randomised controlled trials were included. These reported results for 64

To evaluate the efficacy and safety of the Tempofilter II for the prevention of a pulmonary thromboembolism (PTE) in patients with lower extremity deep vein thrombosis (DVT). Between January 2007 and December 2008, thirteen patients with lower extremity DVT whom were implanted with the Tempofilter II to prevent PTE were analyzed. A chest CT was compared before and after filter placement, to evaluate effectiveness of preventing PTE. Clinical symptoms of PTE were checked. Fluoroscopy and a plain radiograph were examined to evaluate filter status. The tempofilter II was successfully inserted in 13 patients. Nine patients underwent endovascular treatment after filter insertion. Trapping of thrombus was evaluated by following CT, venography, and filter retrieval. Trapped thrombus was detected in four patients by CT or retrieved filter. Two patients showed a decrease in thrombus in a follow-up chest CT. Not all patients showed symptoms of PTE. One filter was surgically removed due to the detachment of the anchoring device. The placement and retrieval of the Tempofilter II is feasible and effective for the prophylaxis of PTE in patients with lower extremity DVT; especially for patients that underwent subsequent endovascular treatment

Little is known about the most effective occupational health and safety (OHS) interventions to reduce upper extremity musculoskeletal disorders (MSDs) and injuries. A systematic review used a best evidence synthesis approach to address the question: "do occupational health and safety interventions have an effect on upper extremity musculoskeletal symptoms, signs, disorders, injuries, claims and lost time?" The search identified 36 studies of sufficient methodological quality to be included in data extraction and evidence synthesis. Overall, a mixed level of evidence was found for OHS interventions. Levels of evidence for interventions associated with positive effects were: Moderate evidence for arm supports; and Limited evidence for ergonomics training plus workstation adjustments, new chair and rest breaks. Levels of evidence for interventions associated with "no effect" were: Strong evidence for workstation adjustment alone; Moderate evidence for biofeedback training and job stress management training; and Limited evidence for cognitive behavioral training. No interventions were associated with "negative effects". It is difficult to make strong evidenced-based recommendations about what practitioners should do to prevent or manage upper extremity MSDs. There is a paucity of high quality OHS interventions evaluating upper extremity MSDs and none focused on traumatic injury outcomes or workplace mandated pre-placement screening exams. We recommend that worksites not engage in OHS activities that include only workstation adjustments. However, when combined with ergonomics training, there is limited evidence that workstation adjustments are beneficial. A practice to consider is using arm supports to reduce upper extremity MSDs.

Although resting heart rate (RHR) and empathy are independently and negatively associated with violent behavior, relatively little is known about the interplay between these psychophysiological and temperament-related risk factors. Using a sample of 160 low-income, racially diverse men followed prospectively from infancy through early adulthood, this study examined whether RHR and empathy during early adolescence independently and interactively predict violent behavior and related correlates in late adolescence and early adulthood. Controlling for child ethnicity, family income, and child antisocial behavior at age 12, empathy inversely predicted moral disengagement and juvenile petitions for violent crimes, while RHR was unrelated to all measures of violent behavior. Interactive effects were also evident such that among men with lower but not higher levels of RHR, lower empathy predicted increased violent behavior, as indexed by juvenile arrests for violent offenses, peer-reported violent behavior at age 17, self-reported moral disengagement at age 17, and self-reported violent behavior at age 20. Implications for prevention and intervention are considered. Specifically, targeting empathic skills among individuals at risk for violent behavior because of specific psychophysiological profiles may lead to more impactful interventions. © 2017 Association for Child and Adolescent Mental Health.

Salt marsh losses have been documented worldwide because of land use change, wave erosion, and sea-level rise. It is still unclear how resistant salt marshes are to extreme storms and whether they can survive multiple events without collapsing. Based on a large dataset of salt marsh lateral erosion rates collected around the world, here, we determine the general response of salt marsh boundaries to wave action under normal and extreme weather conditions. As wave energy increases, salt marsh response to wind waves remains linear, and there is not a critical threshold in wave energy above which salt marsh erosion drastically accelerates. We apply our general formulation for salt marsh erosion to historical wave climates at eight salt marsh locations affected by hurricanes in the United States. Based on the analysis of two decades of data, we find that violent storms and hurricanes contribute less than 1% to long-term salt marsh erosion rates. In contrast, moderate storms with a return period of 2.5 mo are those causing the most salt marsh deterioration. Therefore, salt marshes seem more susceptible to variations in mean wave energy rather than changes in the extremes. The intrinsic resistance of salt marshes to violent storms and their predictable erosion rates during moderate events should be taken into account by coastal managers in restoration projects and risk management plans.

There is little known about Hong Kong juvenile offenders on probation. The purpose of this study was to compare Hong Kong juvenile violent with non-violent probationers on static demographic and psychological variables. The study comprised 109 male juvenile probationers aged 14-20 years (M = 16.97, SD = 1.44) in community transitional housing; 34 were adjudicated for violent offenses, while 75 were non-violent. The Rosenberg Self-Esteem Scale (RSES), Satisfaction with Life Scale (SWLS), Social Bonding Scale-Theft (SBS-T), Social Bonding Scale-Violent Crime (SBS-VC), Positive and Negative Affect Scales (PANAS), Impulsiveness Scale-Short Form (IS-SF) and CRIME-PICS II were administered to measure self-esteem, life satisfaction, social bond, positive and negative affect, impulsivity, pro-offending attitudes, and self-perceived life problems. Data on onset age of delinquent behavior, age of first adjudication, number of prior adjudications, and frequency of self-reported delinquency in the past year were also collected. t-tests were consistent with significant differences for violent offenders including higher self-esteem (p Non-violent offenders self-reported significantly more theft (p non-violent crime, while 58.7% of non-violent offenders reported only non-violent crime. For violent and non-violent offenders, the onset of delinquency was inversely related to the frequency of self-reported delinquency. Using ordinary least-squares (OLS) regression analyses, self-anticipated violent reoffending risk was predicted by age of onset, frequency of self-reported delinquency, social bond (inversely), and impulsivity, while non-violent reoffending risk was predicted by the number of prior convictions and self-reported delinquency. Only two psychological correlates, social bond and impulsivity, were related to violent delinquency; interventions are suggested. Copyright © 2012 John Wiley & Sons, Ltd.

Based on the uses and gratifications perspective, personality was expected to relate to violent video game play frequency and game preferences. Participants completed measures of personality and frequency of violent video game play, and identified their most frequently played video games. Results indicate that individuals higher in openness but lower in agreeableness played violent video games more frequently. In addition, more open and extroverted but less agreeable and neurotic individuals generally preferred to play video games that are more violent. Results suggest personality may be more predictive of violent video game use than traditional media use, though the predictive personality dimensions may be consistent across media types.

Violence in the work place is a new but growing problem for our profession. It is likely that at some point a psychiatrist will be confronted with a potentially violent patient or need to assess a violent patient. Understanding predictors and associated factors in violence as well as having a clear and well-defined strategy in approaching and dealing with the violent patient, thus, are crucial. Ensuring patient, staff, and personal safety is the most important aspect in the management of a violent patient. All of the staff must be familiar with management strategies and clear guidelines that are implemented and followed when confronted with a violent patient. The more structured the approach to the violent patient, the less likely a bad outcome will occur. Manipulating one's work environment to maximize safety and understanding how to de-escalate potentially mounting violence are two steps in the approach to the violent patient. Restraint, seclusion, and psychopharmacologic interventions also are important and often are necessary components to the management of the violent patient.

Collective action will be effective in achieving broader social change goals to the extent that it influences public opinion yet the degree to which collective action "works" in changing opinion is rarely studied. Experiment 1 (n = 158) showed that, consistent with a logic of strategic non-violence, non-violent collective action more effectively conveys a sense of the illegitimacy of the issue and the efficacy of the group, thereby promoting support for future non-violent actions. Experiment 2 (n = 139) explored the moderating role of allegations of corruption. A social context of corruption effectively undermined the efficacy and legitimacy of non-violent collective action, relative to support for violence, thereby promoting (indirectly) support for future extreme action. The implications of this research, for the logic of strategic non-violence and mobilizing supportive public opinion, are discussed.

Although exposure to peer and family violence is a documented risk factor for adolescent dating violence, less is known about the relationship between violent crime exposure and dating violence victimisation. Participants in the National Longitudinal Study of Adolescent Health (n = 4794) aged 13-17 years self-reported witnessing violent crime (someone being shot or stabbed) in the 12 months prior to Wave I interview (1994-95), physical partner violence victimisation within the 18 months prior to Wave II interview (1995-96), and physical and sexual partner violence victimisation within the 18 months prior to Wave III interview (2001). Twelve per cent of respondents reported dating violence victimisation at Wave II. Witnessing violent crime was positively associated with victimisation in crude (OR = 2.11, 95% CI 1.56 to 2.86) and adjusted (AOR = 1.53, 95% CI 1.09 to 2.15) analyses. Of the adolescent partner violence victims (n = 549), 32% reported continued victimisation into early adulthood; after adjusting for gender, age, urbanicity and childhood maltreatment history, witnessing violent crime in adolescence was negatively associated with having non-violent relationships in early adulthood (AOR = 0.40, 95% CI 0.19 to 0.84). In cross-sectional and longitudinal analyses, associations between violent crime exposure and victimisation did not vary by age, gender or race/ethnicity. Adolescents exposed to violent crime experience an increased risk of partner violence victimisation in adolescence and continuing victimisation into adulthood. Targeting dating violence prevention and intervention programmes to geographic areas with high levels of violent crime may be an efficient strategy to reach higher risk adolescents. Reducing community violent crime may also have spillover effects on partner violence.

Full Text Available Many studies on Hamilton's (1964 inclusive fitness theory have used the burning house and kidney donation examples of life-threatening altruism. However, these examples may not be sufficiently exhibiting the risk involved with life-threatening altruism that would have occurred in hunter-gatherer societies, such as fighting off attackers and/or predators. The present study examined participants' estimated likelihood to perform altruistic acts for specific kin members/friends in two violent life-threatening situations (i.e., being mugged and being chased and two non-violent life-threatening situations (i.e., the burning house and kidney donation examples. Participants were 216 undergraduate students who completed a questionnaire on altruism toward an actual kin member/friend. Each questionnaire contained four life-or-death scenarios (two violent and two non-violent in which either the participant's sibling, cousin, or best friend was in danger and needed help. Results indicated that people were more likely to help siblings than cousins and friends in both the violent and non-violent hypothetical scenarios. Participants indicated a greater likelihood to help people in violent situations than in non-violent situations. Women indicated a greater estimated likelihood than men to help people in non-violent situations while men indicated a greater estimated likelihood than women to help people in violent situations. Both male and female participants indicated a greater estimated likelihood to help women than men in violent situations.

We examined the prevalence of and factors associated with violent and heated disagreements in the Asian American families, with an emphasis on place of birth differences between parent and child. Data were obtained from the 2003 National Survey of Children's Health, limited to five states with the highest concentration of Asian-Americans (n = 793). Multivariable analysis used generalized logistic regression models with a three-level outcome, violent and heated disagreement versus calm discussion. Violent disagreements were reported in 13.7% of Asian-American homes and 9.9% of white homes. Differential parent-child place of birth was associated with increased odds for heated disagreement in Asian-American families. Parenting stress increased the likelihood of violent disagreements in both Asian-American and white families. Asian-American families are not immune to potential family violence. Reducing parenting stress and intervening in culturally appropriate ways to reduce generation differences should be violence prevention priorities.

Psychological determinants of aggressive behavior (personality traits and problem behaviors) in 59 Dutch female offenders (outpatients and detainees) were compared with those in 170 male offenders (outpatients and detainees) who were all convicted of a violent crime. The violent female offenders scored significantly higher on neuroticism and trait anger, and significantly lower on hostility than the male offenders; however, effect sizes were small. A subgroup of female forensic psychiatric outpatients did not differ from a subgroup of male outpatients on all measures, whereas a subgroup of female detainees scored significantly higher on anger and aggression, but lower on hostility and psychopathy than did a subgroup of male detainees. These first results might indicate that violent female offenders do not differ much from violent male offenders regarding personality traits and problem behaviors. The differences between both groups of violent offenders were largely borne by the subgroup of violent female detainees compared with the subgroup of violent male detainees.
Previous research has shown how, why, and for whom violent video game play is related to aggression and aggression-related variables. In contrast, less is known about whether some individuals are more likely than others to be the target of increased aggression after violent video game play. The present research examined the idea that the effects of violent video game play are stronger when the target is a member of an outgroup rather than an ingroup. In fact, a correlational study revealed that violent video game exposure was positively related to ethnocentrism. This relation remained significant when controlling for trait aggression. Providing causal evidence, an experimental study showed that playing a violent video game increased aggressive behavior, and that this effect was more pronounced when the target was an outgroup rather than an ingroup member. Possible mediating mechanisms are discussed.

The headrace tunnels at the Jinping II Hydropower Station cross the Jinping Mountain with a maximum overburden depth of 2,525 m, where 80% of the strata along the tunnels consist of marble. A number of extremely intense rockbursts occurred during the excavation of the auxiliary tunnels and the drainage tunnel. In particular, a tunnel boring machine (TBM) was destroyed by an extremely intense rockburst in a 7.2-m-diameter drainage tunnel. Two of the four subsequent 12.4-m-diameter headrace tunnels will be excavated with larger size TBMs, where a high risk of extremely intense rockbursts exists. Herein, a top pilot tunnel preconditioning method is proposed to minimize this risk, in which a drilling and blasting method is first recommended for the top pilot tunnel excavation and support, and then the TBM excavation of the main tunnel is conducted. In order to evaluate the mechanical effectiveness of this method, numerical simulation analyses using the failure approaching index, energy release rate, and excess shear stress indices are carried out. Its construction feasibility is discussed as well. Moreover, a microseismic monitoring technique is used in the experimental tunnel section for the real-time monitoring of the microseismic activities of the rock mass in TBM excavation and for assessing the effect of the top pilot tunnel excavation in reducing the risk of rockbursts. This method is applied to two tunnel sections prone to extremely intense rockbursts and leads to a reduction in the risk of rockbursts in TBM excavation.

Thanks to new heavy ion beams (Argon, Krypton...) accelerated at Ganil and Sara to velocities of about 0.2 to 0.5 times the light one, very violent collisions, between complex nuclei can be made. During peripheral collisions, the projectile is strongly heated in '' wearing away'' the target and follows its way at high velocity in loosing nucleons. Resulting fragments can present themselves as nuclei very different from usual stable nuclei, often at existence limit. In more central collisions, the energy transferred is such that fusion of both leads to a new type of very hot nucleus near the immediate boiling. Another existence limit is reached by this way: where the bound nucleon system tend to become nucleon gas or a bulk of little fragments [fr

Wax deposition is a detrimental problem that happens during crude oil production and transportation, which greatly reduces transport efficiency and causes huge economic losses. To avoid wax deposition, a bioinspired composite coating with excellent wax prevention and anticorrosion properties is developed in this study. The prepared coating is composed of three films, including an electrodeposited Zn film for improving corrosion resistance, a phosphating film for constructing fish-scale morphology, and a silicon dioxide film modified by a simple spin-coating method for endowing the surface with superhydrophilicity. Good wax prevention performance has been investigated in a wax deposition test. The surface morphology, composition, wetting behaviors, and stability are systematically studied, and a wax prevention mechanism is proposed, which can be calculated from water film theory. This composite coating strategy which shows excellent properties in both wax prevention and stability is expected to be widely applied in the petroleum industry.

Little is understood about childhood traumatic brain injury (TBI) and lifetime violent crime perpetration. The purpose was to evaluate TBI before the age of 15 years and other childhood environmental factors, mental health, and lifetime history of committing a violent crime. A cross-sectional study of 636 male and female offenders from a southeastern state prison population was conducted using Chi-squared tests, t tests, and logistic regression to determine factors associated with ever committing a violent crime. Committing a violent crime was associated with male gender, younger age, greater childhood sexual abuse (CSA), greater childhood emotional abuse, no TBI by the age of 15 years, and greater neighborhood adversity during childhood. Although TBI has been related to violent and nonviolent crime, this study showed that absence of TBI by the age of 15 years was associated with lifetime violent crime when adjusting for CSA, childhood emotional abuse, and neighborhood adversity during childhood. This builds upon neurobehavioral development literature suggesting that CSA and the stress of violence exposure without direct physical victimization may play a more critical role in lifetime violent criminal behavior than childhood TBI. Violence risk reduction must occur during childhood focusing on decreasing adversity, especially violence exposure as a witness as well as a direct victim.

Doctors, lawyers and criminal justice agencies need methods to assess vulnerability to violent radicalization. In synergy, public health interventions aim to prevent the emergence of risk behaviours as well as prevent and treat new illness events. This paper describes a new method of assessing vulnerability to violent radicalization, and then investigates the role of previously reported causes, including poor self-reported health, anxiety and depression, adverse life events, poverty, and migration and socio-political factors. The aim is to identify foci for preventive intervention. A cross-sectional survey of a representative population sample of men and women aged 18-45, of Muslim heritage and recruited by quota sampling by age, gender, working status, in two English cities. The main outcomes include self-reported health, symptoms of anxiety and depression (common mental disorders), and vulnerability to violent radicalization assessed by sympathies for violent protest and terrorist acts. 2.4% of people showed some sympathy for violent protest and terrorist acts. Sympathy was more likely to be articulated by the under 20s, those in full time education rather than employment, those born in the UK, those speaking English at home, and high earners (>£75,000 a year). People with poor self-reported health were less likely to show sympathies for violent protest and terrorism. Anxiety and depressive symptoms, adverse life events and socio-political attitudes showed no associations. Sympathies for violent protest and terrorism were uncommon among men and women, aged 18-45, of Muslim heritage living in two English cities. Youth, wealth, and being in education rather than employment were risk factors.

Etiological theory and prior research with small or selected samples suggest that interpersonal violence clusters in families. However, the strength and pattern of this aggregation remains mostly unknown. We investigated all convictions for violent crime in Sweden 1973-2004 among more than 12.5 million individuals in the nationwide Multi-Generation Register, and compared rates of violent convictions among relatives of violent individuals with relatives of matched, non-violent controls, using a nested case-control design. We found strong familial aggregation of interpersonal violence among first-degree relatives [e.g. odds ratio (OR)sibling 4.3, 95% confidence interval (CI) 4.2-4.3], lower for more distant relatives (e.g. OR cousin 1.9, 95% CI 1.9-1.9). Risk patterns across biological and adoptive relations provided evidence for both genetic and environmental influences on the development of violent behavior. Familial risks were stronger among women, in higher socio-economic strata, and for early onset interpersonal violence. There were crime-specific effects (e.g. OR sibling for arson 22.4, 95% CI 12.2-41.2), suggesting both general and subtype-specific familial risk factors for violent behavior. The observed familiality should be accounted for in criminological research, applied violence risk assessment, and prevention efforts.

In response to concerns regarding the rise in female juvenile violent crime and the dearth of gender-specific research, this study aimed to identify predictors of violent offending in female offenders. Data were extracted from risk assessments of 586 male and female juvenile offenders (aged 11-17 years) conducted between 2005 and 2009 by the Youth Offending Service in Gloucestershire, an English county. Information regarding the young people's living arrangements, family and personal relationships, education, emotional/mental health, thinking and behavior, and attitudes to offending was recorded. Comparisons were made between the violent male offenders (N = 185), the violent female offenders (N = 113), the non-violent male offenders (N = 150), and the non-violent female offenders (N = 138) for these variables. These were followed by a multinomial logistic regression analysis. The findings indicated that engaging in self-harm was the best predictor of being a female violent offender, with the predictors of giving into pressure from others and attempted suicide nearing significance. Furthermore, non-violent females were significantly less likely to lose control of their temper and more likely to give in to pressure from others than their violent counterparts. Non-violent males were significantly less likely to lose control of their temper and more likely to self-harm and give in to pressure from others than violent males. Although many similarities existed between sexes for predictors of violent offending, the findings of this study indicate that more attention needs to be paid to the mental health of female offenders. © 2013 Wiley Periodicals, Inc.

Understanding the mechanisms and processes underlying the dynamics of collective violence is of considerable current interest. Recent studies indicated the presence of robust patterns characterizing the size and timing of violent events in human conflicts. Since the size and timing of violent events arises as the result of a dynamical process, we explore the possibility of unifying these observations. By analyzing available catalogs on violent events in Iraq (2003-2005), Afghanistan (2008-2010) and Northern Ireland (1969-2001), we show that the inter-event time distributions (calculated for a range of minimum sizes) obeys approximately a simple scaling law which holds for more than three orders of magnitude. This robust pattern suggests a hierarchical organization in size and time providing a unified picture of the dynamics of violent conflicts.
We reexamine the foundations of Lynden-Bell's statistical mechanical discussion of violent relaxation in collisionless stellar systems. We argue that Lynden-Bell's formulation in terms of a continuum description introduces unnecessary complications, and we consider a more conventional formulation in terms of particles. We then find the exclusion principle discovered by Lynden-Bell to be quantitatively important only at phase densities where two-body encounters are no longer negligible. Since the edynamical basis for the exclusion principle vanishes in such cases anyway, Lynden-Bell statistics always reduces in practice to Maxwell-Boltzmann statistics when applied to stellar systems. Lynden-Bell also found the equilibrium distribution function generally to be a sum of Maxwellians with velocity dispersions dependent on the phase density at star formation. We show that this difficulty vanishes in the particulate description for an encounterless stellar system as long as stars of different masses are initially well mixed in phase space. Our methods also demonstrate the equivalence between Gibbs's formalism which uses the microcanonical ensemble and Boltzmann's formalism which uses a coarse-grained continuum description. In addition, we clarify the concept of irreversible behavior on a macroscopic scale for an encounterless stellar system. Finally, we comment on the use of unusual macroscopic constraints to simulate the effects of incomplete relaxation

In this cross-sectional study we explored relationships between aggressive and violent behaviors and emotional self-efficacy (ESE) in a statewide sample of public high school adolescents in South Carolina (N = 3836). The US Centers for Disease Control and Prevention Youth Risk Behavior Survey items on aggressive and violent behavior items and an adolescent ESE scale were used. Logistic regression analyses and multivariate models constructed separately, revealed significant race by sex findings. Results suggest that carrying a weapon to school (past 30 days) and being threatened or injured with a gun, knife, or club at school (past 12 months) were significantly associated (p emotional learning and aggression/violence prevention programs for adolescents.

This article bridges scholarship in criminology and family sociology by extending arguments about “precocious exits” from adolescence to consider early union formation as a salient outcome of violent victimization for youths. Research indicates that early union formation is associated with several negative outcomes; yet the absence of attention to union formation as a consequence of violent victimization is noteworthy. We address this gap by drawing on life course theory and data from the National Longitudinal Study of Adolescent Health (Add Health) to examine the effect of violent victimization (“street” violence) on the timing of first co-residential union formation—differentiating between marriage and cohabitation—in young adulthood. Estimates from Cox proportional hazard models show that adolescent victims of street violence experience higher rates of first union formation, especially marriage, early in the transition to adulthood; however, this effect declines with age, as such unions become more normative. Importantly, the effect of violent victimization on first union timing is robust to controls for nonviolent delinquency, substance abuse, and violent perpetration. We conclude by discussing directions for future research on the association between violent victimization and coresidential unions with an eye toward the implications of such early union formation for desistance.

This article aims to explore and report on violent thinking and alcohol misuse; how these factors may predict self-reported violence. The role of violent thinking in violent behavior is both well established in theoretical models, yet there are few measures that explain this role. One measure that has been identified is the Maudsley Violence Questionnaire (MVQ). This is the first study to explore the use of the MVQ with a general (nonoffender) adult sample, having already been shown to be valid with young people (under 18 years old), adult male offenders, and mentally disordered offenders. This study involved 808 adult participants-569 female and 239 male participants. As figures demonstrate that around half of all violent crime in the United Kingdom is alcohol related, we also explored the role of alcohol misuse. Regression was used to explore how these factors predicted violence. The results demonstrate the important role of violent thinking in violent behavior. The MVQ factor of "Machismo" was the primary factor in regression models for both male and female self-reported violence. The role of alcohol in the regression models differed slightly between the male and female participants, with alcohol misuse involved in male violence. The study supports theoretical models including the role of violent thinking and encourages those hoping to address violence, to consider "Machismo" as a treatment target. The study also provides further validation of the MVQ as a helpful tool for clinicians or researchers who may be interested in "measuring" violent thinking.

Preventing respiratory diseases caused by airborne microbes in enclosed spaces is still not satisfactorily controlled. At extremely low concentrations (about 30 parts per billion), chlorine dioxide (ClO2) gas can inactivate airborne microbes and prevent respiratory disease. It has no toxic effect on animals at this level. However, controversies still remain regarding how to measure concentrations of ClO2 gas at such low levels. It is therefore necessary to prove that measured gas concentrations are accurate and reproducible. ClO2 gas was released from a gas generator and its concentration was measured by a novel highly sensitive gas analyzer. We compared its data with those from ion chromatography. We demonstrate that the gas concentrations measured in a room using the gas analyzer are accurate and reproducible after comparing the results with those from ion chromatography. However, the temperature dependence of the gas analyzer was found. Therefore, data correction is required for each temperature at which gas concentration is measured. A theoretical analysis of the gas concentrations predicted by the rate of ClO2 gas released from the ClO2 generator was also performed. Our results advance progress toward using low concentration ClO2 gas to prevent airborne infectious diseases such as influenza. © 2016 S. Karger AG, Basel.

Chinese herbal medicine has traditionally been considered to promote blood circulation to remove obstruction in the channels and clear pathogenic heat to drain dampness effects. We conducted this meta-analysis to evaluate its benefits for the prevention of deep venous thrombosis (DVT) after lower extremity orthopedic surgery. Relevant, published studies were identified using the following keywords: lower extremity orthopedic surgery, arthroplasty, joint replacement, fracture, traditional Chinese and western medicine, Chinese herbal medicine, deep venous thrombosis (DVT), and Venous thromboembolism (VTE). The following databases were used to identify the literature consisting of RCTs with a date of search of 31 May 2017: PubMed, Cochrane Library, Web of knowledge, the Chinese National Knowledge Infrastructure Database, the Chongqing VIP Database, the Chinese Biomedical Database, and the Wanfang Database (including three English and four Chinese databases). All relevant data were collected from studies meeting the inclusion criteria. The outcome variables were the incidence rate of DVT, activated partial thromboplastin time (APTT), prothrombin time (PT), and D-dimer; subcutaneous hematoma; and other reported outcomes. RevMan5.2. software was adopted for the meta-analysis. A total of 20 published studies (1862 cases) met the inclusion criteria. The experimental group, 910 patients (48.87%), received the Chinese herbal medicine or traditional Chinese and western medicine for prevention of DVT; the control group, 952 patients (51.13%), received the standard western treatment. The meta-analysis showed that traditional Chinese and western medicine therapy reduced the incidence rates of DVT significantly when compared with controls (risk ratio [RR] = 0.40; 95% CI, 0.30 to 0.54; P < 0.00001), and the D-dimer was lower in the experimental group (P = 0.01). Besides, the incidence rate of subcutaneous hematoma was lower in the experimental group (P < 0

With the availability of new functional and structural neuroimaging techniques, researchers have begun to localize brain areas that may be dysfunctional in offenders who are aggressive and violent. Our review of 17 neuroimaging studies reveals that the areas associated with aggressive and/or violent behavioral histories, particularly impulsive acts, are located in the prefrontal cortex and the medial temporal regions. These findings are explained in the context of negative emotion regulation, and suggestions are provided concerning how such findings may affect future theoretical frameworks in criminology, crime prevention efforts, and the functioning of the criminal justice system.

Starting with a view of war as a significant population health problem, this article explores the roles of health workers in relation to violent conflict. Four different roles are identified, defined by goals and values--military, development, humanitarian and peace. In addition, four dimensions...... of health work are seen as cross-cutting factors influencing health work in violent conflict-- whether the health worker is an insider or outsider to the conflict, whether they are oriented to primary, secondary or tertiary prevention of the mortality and morbidity of war, whether they take an individual...
Full Text Available Research on disengagement from violent extremism is an emerging field of inquiry. As compared to the related field of radicalization, there have been fewer studies of disengagement. Further, little effort has been made to conduct a large scale, systematic review of what is currently known about disengagement from violent extremism. This type of meta-literature assessment can play an important role in terms of informing strategies and programs designed to facilitate exit. To help fill this gap, our project systematically examines the disengagement literature to determine the range and frequency of various exit factors identified in previous studies. We also rely on parallel literatures such as exit from street gangs, mainstream religious groups, cults, and nonviolent social movements to build a robust sample of studies that assess the extent to which group exit factors may generalize across different populations.

Radical and contentious political/religious activism may or may not evolve into violent behavior depending on contextual factors related to social, political, cultural and infrastructural conditions. Significant theoretical advances have been made in understanding these contextual factors and the import of their interrelations. However, there has been relative little progress in the development of processes and capabilities which leverage such theoretical advances to automate the anticipatory analysis of violent intent. In this paper, we describe a framework which implements such processes and capabilities, and discuss the implications of using the resulting system to assess the emergence of radicalization leading to violence.

Little is known about the relative extent of crime against people with severe mental illness (SMI). To assess the prevalence and impact of crime among people with SMI compared with the general population. A total of 361 psychiatric patients were interviewed using the national crime survey questionnaire, and findings compared with those from 3138 general population controls participating in the contemporaneous national crime survey. Past-year crime was experienced by 40% of patients v. 14% of controls (adjusted odds ratio (OR) = 2.8, 95% CI 2.0-3.8); and violent assaults by 19% of patients v. 3% of controls (adjusted OR = 5.3, 95% CI 3.1-8.8). Women with SMI had four-, ten- and four-fold increases in the odds of experiencing domestic, community and sexual violence, respectively. Victims with SMI were more likely to report psychosocial morbidity following violence than victims from the general population. People with SMI are at greatly increased risk of crime and associated morbidity. Violence prevention policies should be particularly focused on people with SMI. Royal College of Psychiatrists.

Bronchopulmonary dysplasia (BPD) is one of the most common consequence of extreme prematurity (birth weight (ELBW) neonates. The aim of this systematic review is to evaluate the role of vitamin A supplementation in prevention of BPD in ELBW neonates. The literature search was done for various randomized control trial (RCT) by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and ongoing clinical trials. This review included two RCTs that fulfilled inclusion criteria. There were statistically significant reduction in the incidence of BPD (oxygen requirement at 36 weeks of postmenstrual age (PMA)) (relative risk (RR) 0.88; 95%CI 0.77-0.99; p = .04; NNTB 14) and borderline significant reduction in combined outcomes of mortality/BPD (oxygen requirement at 36 weeks of PMA) (RR 0.90; 95%CI 0.82-1.00; p = .05). However, oxygen requirement at 28 days of life and combined outcome of mortality/BPD (oxygen requirement at 28 days of life) were not statistically significant. The role of vitamin A supplementation in the prevention of BPD is supported by the current evidences. However, due to limited number of studies, current evidences are not sufficient which can translate into routine clinical practice. We need large high-quality trials, with sufficient power to reliably assess clinically relevant differences in outcomes.

To evaluate the mid- and long-term outcomes of inferior vena cava (IVC) filter insertion in patients with underlying deep vein thrombosis for prevention of pulmonary thromboembolism, based on a single center experience. A total of 166 IVC filter insertion procedures in 160 patients, between February 2004 and December 2014, were retrospectively reviewed. Severity of deep vein thrombosis, indwelling time of the IVC filter, retrieval rate, and complication rate depending on the type of IVC filter were analyzed based on the patients' radiologic findings and medical records. IVC filter insertion procedures were successfully performed in all patients. Among the 99 attempts at filter retrieval, 91 trials succeeded (91.9%, 91/99) and 8 trials failed. Indwelling time of the IVC filter showed a positive correlation with failure of filter retrieval (p = 0.01). There was no procedure-related complication after all IVC filter insertion procedures. Eight delayed complications (5.0%, 8/160 patients with IVC filter insertion) were observed [caval thrombosis below the IVC filter (n = 7) and IVC penetration (n = 1)]. Günther Tulip filter was associated with a significant incidence of complication (p = 0.036). IVC filter insertion in patients with lower extremity deep vein thrombosis for prevention of pulmonary thromboembolism can be regarded as a safe treatment modality with an acceptable complication rate

Full Text Available Background: Considering the importance of anger, aggression, violence and other misbehaviours in schoolchildren education, the present study was conducted to evaluate the knowledge and practice of students in Isfahan province regarding violence, in order to figure out the required interventions for violence-reduction. Methods: In a survey during 2008-2009, 5500 junior and senior high school students of Isfahan province were assessed in a multistage sampling process to determine their level of knowledge about various types of violent behaviors, causes of violence, its consequences, and preventive behaviors. Validity and reliability of the data collection tool (questionnaire were assessed. Results: The study revealed that the mean scores of violent behaviors knowledge, knowledge of violent behavior outcomes, and knowledge of violence preventive behaviors, were 6.6 ± 2.1, 5.5 ± 1.9, and 4.7 ± 1.3, respectively. Sources of violent behaviors in 92% of urban students and 89% of rural students were personal reasons and family behaviors, and 85% of urban and 88% of rural students considered mass media and computer games blameworthy, and the differences were statistically significant in all cases (P < 0.0001. In terms of practice, overall, 69.7% of girls and 84.2% of boys had violent behaviors. Physical and verbal violence were 31.3% and 40.7%in girls, and 66% and 52.8% in boys, respectively (intersexes P values were P < 0.001 and P = 0.7 respectively, and intra-sex P value was P < 0.0001. Conclusions: Results showed that girls and city dwellers were more aware of recognizing violent behaviors, outcomes, and causes, compared with boys and villagers, and in terms of general practice, violence was observed among boys more than girls. Further complementary studies in this area seem required.

Exposure to media violence is associated with increased aggression and its sequelae. Unfortunately, the majority of entertainment video games contain violence. Moreover, children of both genders prefer games with violent content. As there is no compulsory legislative standards to limit the type and amount of violence in video games, concerned adults must assume an oversight role.

Full Text Available Introduction: Accidents and assaults (homicides are the leading causes of death among the youth of the United States, accounting for 53.3% of deaths among children aged 1 to19 years. Victim recidivism,defined as repeated visits to the emergency department (ED as a victim of violent trauma, is a significantly growing public health problem. As 5-year mortality rates for recidivism are as high as 20%,it is important to determine whether victims with a history of violent trauma are at increased risk for fatal outcome with their next trauma. We hypothesized that victims of violent trauma who have had 1 prior ED visit for violent trauma will have increased odds of fatal outcome.Methods: A retrospective chart review was conducted for patients presenting with penetrating trauma to the ED from January 1, 1999 to December 31, 2009. All patients between the ages of 15 to 25 years who presented to the ED for any penetrating trauma were included. Patients with prior presentations for penetrating trauma were compared to those patients who were first-time presenters to determine the odds ratio of fatal outcome.Results: Overall, 15,395 patients were treated for traumatic presentations. Of these, 1,044 met inclusion criteria. Demographically, 79.4% were Hispanic, 19.4% were African American, and 0.96% were Caucasian. The average age was 21 years, and 98% of the population was male. One hundred and forty-seven (14% had prior presentations, and 897 (86% did not. Forty of the 147 patients (27%with prior presentations had a fatal outcome as compared to 29 patients of the 868 (3% without prior presentations, with odds ratio of 10.8 (95% confidence interval, 6.4–18.1; Pearson v2, P , 0.001. The 5-year mortality rate for those patients with fatal outcomes was calculated at 16.5%.Conclusion: Patients who had prior ED visits for penetrating trauma were at greater risk for fatal outcomes compared to those with no prior visits. Therefore, trauma-related ED visits might

The disabling injuries inflicted during road traffic accidents (RTA) create a serious challenge for the public health services and are at the same time a major socio-economic problem in the majority of the countries throughout the world. The injuries to the lower extremities of the pedestrians make up the largest fraction of the total number of the non-lethal RTA injuries. Most of them are responsible for the considerable deterioration of the quality of life for the participants in the accidents during the subsequent period. The objective of the present study was to summarize the currently available results of experimental testing of the biomechanical models of the pedestrians' lower extremities in the framework of the program for the prevention of the road traffic accidents as proposed by the World Health Organization (WHO, 2004). The European Enhanced Safety Vehicle Committee (EEVC) has developed a series of crash-tests with the use of the models of the pedestrians' lower extremities simulating the vehicle bumper-pedestrian impact. The models are intended for the assessment of the risk of the tibia fractures and the injuries to the knee joint ligaments. The experts of EEVC proposed the biomechanical criteria for the acceleration of the knee and talocrural parts of the lower limbs as well as for the shear displacement of the knee and knee-bending angle. The engineering solution of this problem is based on numerous innovation proposals being implemented in the machine-building industry with the purpose of reducing the stiffness of structural elements of the bumper and other front components of a modern vehicle designed to protect the pedestrians from severe injuries that can be inflicted in the road traffic accidents. The activities of the public health authorities (in the first place, bureaus of forensic medical expertise and analogous facilities) have a direct bearing on the solution of the problem of control of road traffic injuries because they are possessed of

Full Text Available This paper examines the role of personality traits and gender in violent interaction among middle school children (11-15 age range. The aim of the research presented here was to determine the contribution of personality traits and gender to various aspects of violent interaction, i.e. predisposition towards and exposure to peer violence. The sample consisted of 344 students from 5th to 8th grade, the majority of whom were girls (60.8%. The instruments used in the research were a questionnaire designed to assess violent behavior in primary school children (PRONA and the Big Five Plus Two inventory (the BF + 2 for children, designed to assess seven basic personality traits in primary school children. The results of a multivariate analysis of covariance suggest that boys tend to perpetrate and be exposed to violent behaviour more than girls, and also that certain personality traits contribute to the manifestation of these constructs. Exposure to violence is determined by low Extraversion, as well as higher levels of Neuroticism and Negative Valence. The traits that contribute most significantly to the tendency towards abusive behaviour are high levels of Aggression and Negative Valence as well as lower levels of Positive Valence. The most effective means of abuse prevention among middle school children is the setting up of prevention programs along with the detection of specific vulnerable groups of students, and the adjustment of these programs to students' personological traits.

Climatic changes are frequently cited as a possible external driver of violent conflict in human societies. Qualitative studies suggest that climatic shifts may stress populations and be conducive to violent conflict. Statistical evidence has shown that anomalous local rainfall is correlated with the onset of conflict. This study finds that in addition to idiosyncratic weather events, climatic states also play a role in triggering violent conflict. El Niño Southern Oscillation (ENSO), the semi-periodic, oceanic Kelvin wave in the tropical Pacific, induces remote temperatures in the tropical free troposphere to rise. This ``ENSO teleconnection'' is not globally uniform and is felt most strongly in the tropical regions during the boreal winter. To determine the degree in which country-level climatic conditions are affected by ENSO, an absolute correlation measure between surface temperature and two ENSO indices was calculated for every country for the period 1949-2009. Countries with high levels of correlation are labeled “ENSO affected,” while countries with low correlation are labeled “ENSO unaffected”. Thus, historical variation in ENSO serves as a ``natural experiment'': if the state of ENSO influences conflict onset, it should be apparent for ENSO affected countries but not for unaffected countries. Using the UCDP/PRIO Armed Conflict Dataset, we find evidence of a large and statistically significant influence of ENSO on the onset of violent conflict. Between 1949-2009, the average probability of a conflict beginning in any country was 0.03. For the ENSO affected countries, we find that a 1°C rise in either NINO12 or NINO34 is associated with an increased probability of conflict onset by 0.015 (or 50% of the global country average). A relationship was not detected for the ENSO unaffected group of countries. This result is robust to a range of statistical models. Nonparametric methods (see figure) also indicate a marked difference in the response of ENSO

Background: Research on the association between testosterone and violent behavior has provided conflicting findings. The majority of studies on the association between testosterone and antisocial-violent behaviors has used a clinical sample of severely violent individuals. These studies have mostly assessed males. Objectives: To study sex differences in the association between testosterone and violent behaviors in a community sample of young adults in the United States. Patients and Methods: A longitudinal study of an inner city population on subjects aged from adolescence to adulthood was undertaken. Testosterone and violent behaviors were measured among 257 young adults with an average age of 22 years (range 21 to 23 years). We used regression analysis to test the association between testosterone and violent behaviors in male and female samples. Results: There was a significant positive correlation between testosterone levels and violent behaviors among females, but not males. The association between testosterone levels and violent behaviors among females was significant, as it was above and beyond the effects of socio-economic status, age, education, and race. Conclusions: Our findings provide more information about the biological mechanisms for violent behaviors among young female adults. The study also helps us better understand sex differences in factors associated with violent behaviors in the community. PMID:25337519

We report a case of a 9-year-old boy with Tourette syndrome (TS) who developed progressive quadriparesis that was more severe in the upper extremities. He had experienced frequent and violent motor tics consisting of hyperflexion and hyperextension for years. Magnetic resonance imaging (MRI) revealed a focal high-signal intensity cord lesion and adjacent cervical spondylotic changes. Initially, the patient was observed for several months because of diagnostic uncertainty; his neurological status had improved and later worsened again. Anterior cervical discectomy of C3-4 and fusion immediately followed by posterior fixation were performed. After surgery, the neck collar was applied for 6 months. His neurological signs and symptoms improved dramatically. TS with violent neck motion may cause cervical spondylotic myelopathy at an early age. The optimal management is still unclear and attempts to control tics should be paramount. Circumferential fusion with neck bracing represents a viable treatment option.

The purpose of this study was to describe women's perceptions of their violent behavior in a heterosexual partnership. The study followed the traditions of Husserlian descriptive phenomenology and the philosophy of existential phenomenology. Twenty-four volunteer Finnish women, aged 19 to 58 years, with a history of different manifestations of intimate partner violence (IPV) participated in open-ended interviews. The data were analyzed by the method developed by Colaizzi. The findings revealed that some of the women who opposed all violence on ethical grounds did not label their behavior as violent; some others minimized or justified their violent behavior. The findings offer professional insight into women's violent behavior and call for a readjustment in approaches to work in the area. Prevention and early identification of IPV require knowledge of the various manifestations and individual meanings of violence. Helping methods should provide women with the opportunity to talk about their abusive behavior and to confront and address their feelings of guilt, disappointment, and shame.

PubMed/MEDLINE and PsycINFO databases were searched using several terms related to severe mental illness in successive combinations with terms describing victimization. The searches identified 34 studies. Nine epidemiological studies indicate that patients with severe mental illness are more likely to be violently victimized than other community members. Young age, comorbid substance use, and homelessness are risk factors for victimization. Victimized patients are more likely to engage in violent behavior than other members of the community. Violent victimization of persons with severe mental illness has long-term adverse consequences for the course of their illness, and further impairs the quality of lives of patients and their families. Victimization of persons with severe mental illness is a serious medical and social problem. Prevention and management of victimization should become a part of routine clinical care for patients with severe mental illness.

The present study aims to examine risk factors and risk-based and interactive protective factors for violent offending in a group of 437 young Australians. Participants were recruited into the study when they were in Grade 5 (10-11 years) and followed up almost annually until young adulthood (18-19 years). Measures of violent offending, risk and protective factors, and demographics were obtained through a modification of the Communities That Care youth survey. The data collected enabled identification of groups of students at-risk of violent offending according to drug use, low family socioeconomic status, and antisocial behavior. Results showed that there were very few associations between the risk factors and risk-based protective factors measured in this study (e.g., belief in the moral order, religiosity, peer recognition for prosocial involvement, attachment to parents, low commitment to school, and poor academic performance) and later self-reported violent offending. There were no statistically significant interactive protective factors. Further longitudinal analyses with large sample sizes are needed to examine risk factors and risk-based protective factors and interactive protective factors in at-risk groups. The findings support the need for multi-faceted prevention and early intervention approaches that target multiple aspects of youth's lives.

Two studies tested the hypothesis that exposure to violent media reduces aid offered to people in pain. In Study 1, participants played a violent or nonviolent video game for 20 min. After game play, while completing a lengthy questionnaire, they heard a loud fight, in which one person was injured, outside the lab. Participants who played violent games took longer to help the injured victim, rated the fight as less serious, and were less likely to "hear" the fight in comparison to participants who played nonviolent games. In Study 2, violent- and nonviolent-movie attendees witnessed a young woman with an injured ankle struggle to pick up her crutches outside the theater either before or after the movie. Participants who had just watched a violent movie took longer to help than participants in the other three conditions. The findings from both studies suggest that violent media make people numb to the pain and suffering of others.

We present a computational approach to modeling the intent of a communication source representing a group or an individual to engage in violent behavior. Our aim is to identify and rank aspects of radical rhetoric that are endogenously related to violent intent to predict the potential for violence as encoded in written or spoken language. We use correlations between contentious rhetoric and the propensity for violent behavior found in documents from radical terrorist and non-terrorist groups and individuals to train and evaluate models of violent intent. We then apply these models to unseen instances of linguistic behavior to detect signs of contention that have a positive correlation with violent intent factors. Of particular interest is the application of violent intent models to social media, such as Twitter, that have proved to serve as effective channels in furthering sociopolitical change.

Adventure and extreme sports often involve unpredictable and inhospitable environments, high velocities, and stunts. These activities vary widely and include sports like BASE jumping, snowboarding, kayaking, and surfing. Increasing interest and participation in adventure and extreme sports warrants understanding by clinicians to facilitate prevention, identification, and treatment of injuries unique to each sport. This article covers alpine skiing and snowboarding, skateboarding, surfing, bungee jumping, BASE jumping, and whitewater sports with emphasis on epidemiology, demographics, general injury mechanisms, specific injuries, chronic injuries, fatality data, and prevention. Overall, most injuries are related to overuse, trauma, and environmental or microbial exposure. Copyright © 2016 Elsevier Inc. All rights reserved.

Research has shown that exposure to violent media increases aggression. However, the neural underpinnings of violent-media-related aggression are poorly understood. Additionally, few experiments have tested hypotheses concerning how to reduce violent-media-related aggression. In this experiment, we focused on a brain area involved in the regulation of aggressive impulses-the right ventrolateral prefrontal cortex (rVLPFC). We tested the hypothesis that brain polarization through anodal transcranial direct current stimulation (tDCS) over rVLPFC reduces aggression related to violent video games. Participants (N = 79) were randomly assigned to play a violent or a nonviolent video game while receiving anodal or sham stimulation. Afterward, participants aggressed against an ostensible partner using the Taylor aggression paradigm (Taylor Journal of Personality, 35, 297-310, 1967), which measures both unprovoked and provoked aggression. Among those who received sham stimulation, unprovoked aggression was significantly higher for violent-game players than for nonviolent-game players. Among those who received anodal stimulation, unprovoked aggression did not differ for violent- and nonviolent-game players. Thus, anodal stimulation reduced unprovoked aggression in violent-game players. No significant effects were found for provoked aggression, suggesting tit-for-tat responding. This experiment sheds light on one possible neural underpinning of violent-media-related aggression-the rVLPFC, a brain area involved in regulating negative feelings and aggressive impulses.

This 1-year retrospective study was conducted on a regional secure unit at the Bethlem Royal Hospital, London, using the hospital's data collection sheet for violent incidents. The majority of incidents were minor in nature but there were a few assaults that involved pain, lacerations or bruising. Although violence was common to the majority of patients, two contributed a large number. Those staff at the bottom of the nursing hierachy who spent most time with patients were most at risk. Likewise fellow patients were also often involved in incidents. Violence did not tail off after the breakfast period, as reported in previous studies, but continued to rise until bedtime.

This is a systematic study of the social background of Danish males convicted for the first time of lethal violence, either actual or potential (e.g. unlawful killers, attempted homicides, negligent homicide, grievous bodily harm, N=125). Using registers, the paper addresses the following question...... of subjects have a similar exposure to risk conditions, but also that there are important differences in the predictors for the three groups when the risk factors are analyzed one by one. So, for example, the experience of domestic violence during adolescence is a strong predictor of males’ later violent...
With today’s unlimited and instantaneous communication, it is easy for a United States citizen to easily connect with anyone in the world. There are many positives to this; however, the unintended consequences include vulnerable people being influenced by radical ideologies. This is evident with the increase in homegrown violent extremists (HVE).The challenge for law enforcement is how to work with constitutional constraints that require a criminal predicate to be present in order to allow intelligence teams to continue collecting information in a permanent file.

Regulating alcohol outlet density is an evidence-based strategy for reducing excessive drinking. However, the effect of this strategy on violent crime has not been well characterized. A reduction in alcohol outlet density in the Buckhead neighborhood of Atlanta from 2003 through 2007 provided an opportunity to evaluate this effect. We conducted a community-based longitudinal study to evaluate the impact of changes in alcohol outlet density on violent crime in Buckhead compared with 2 other cluster areas in Atlanta (Midtown and Downtown) with high densities of alcohol outlets, from 1997 through 2002 (preintervention) to 2003 through 2007 (postintervention). The relationship between exposures to on-premises retail alcohol outlets and violent crime were assessed by using annual spatially defined indices at the census block level. Multilevel regression models were used to evaluate the relationship between changes in exposure to on-premises alcohol outlets and violent crime while controlling for potential census block-level confounders. A 3% relative reduction in alcohol outlet density in Buckhead from 1997-2002 to 2003-2007 was associated with a 2-fold greater reduction in exposure to violent crime than occurred in Midtown or Downtown, where exposure to on-premises retail alcohol outlets increased. The magnitude of the association between exposure to alcohol outlets and violent crime was 2 to 5 times greater in Buckhead than in either Midtown or Downtown during the postintervention period. A modest reduction in alcohol outlet density can substantially reduce exposure to violent crime in neighborhoods with high density of alcohol outlets. Routine monitoring of community exposure to alcohol outlets could also inform the regulation of alcohol outlet density, consistent with Guide to Community Preventive Services recommendations.

A basic framework for developing an advocacy plan must systematically break down the large task of policy development implementation into manageable components. The basic framework described in detail in this paper includes three steps: Setting policy objectives by narrowing the scope of policy, by reviewing policy options, and by examining options against selected criteria. Developing strategies for educating the public and for approaching legislative/regulatory bodies. Evaluating the effectiveness of the advocacy action plan as a process and as an agent for change. To illustrate the variety of ways in which pediatricians can be involved in the policy process to reduce violent injuries among children and adolescents, we apply this systematic approach to three priority areas. Prohibiting the use of corporal punishment in schools is intended to curb the institutionalized legitimacy of violence that has been associated with future use of violence. Efforts to remove handguns from the environments of children and adolescents are aimed at reducing the numbers of firearm injuries inflicted upon and by minors. Comprehensive treatment of adolescent victims of assault is intended to decrease the reoccurrence of violent injuries.

Up to now, victimology has only dealt with partial aspects of the situation of the elderly as victims of violent crime. Nevertheless, the Police Crime Statistics enable us to make the following three basic statements: In general, old people are less likely to become victims of violent crime (than young people). The acts of violence committed against the elderly are mainly ones in which there was a relationship between offender and victim before the offense. Elderly women are disproportionately more often victims of purse snatching. The increasing social isolation of old people constitutes not only a specific form of victimization, it probably also increases their susceptibility to become victims. The theory that old people have "a particularly pronounced fear of crime" cannot be generally proven. This question must be considered from differing points of view and depends largely on the individual vulnerability of the old people. In Germany, there has hardly been any empirical study of violence towards the elderly in institutions and in family households (so-called domestic violence). It is believed that more violence takes place in both than in generally assumed.

The objective was to evaluate a new scale aimed at assessing antisocial attitudes, the Pro-bullying Attitude Scale (PAS), on a group of 259 voluntarily-recruited male juvenile delinquents from a juvenile correctional institution in Arkhangelsk, North-western Russia. Exploratory factor analysis gave a two-factor solution: Factor 1 denoted Callous/Dominance and Factor 2 denoted Manipulativeness/Impulsiveness. Subjects with complete data on PAS and Childhood Psychopathy Scale (CPS) (n=171) were divided into extreme groups (first and fourth quartiles) according to their total scores on PAS and the two factor scores, respectively. The extreme groups of total PAS and PAS Factor 1 differed in CPS ratings and in violent behavior as assessed by the Antisocial Behavior Checklist (ABC). They also differed in the personality dimension Harm Avoidance as measured by use of the Temperament and Character Inventory (TCI), and in delinquent and aggressive behavior as assessed by the Youth Self Report (YSR). The extreme groups of PAS Factor 2, in turn, differed in aggressive behavior as assessed by the YSR, and in the TCI scale Self-Directedness. When PAS was used as a continuous variable, total PAS and PAS Factor 1 (Callous/Dominance) were significantly positively related to registered violent crime. The possible usefulness of PAS in identifying high-risk individuals for bullying tendencies among incarcerated delinquents is discussed. Copyright © 2013. Published by Elsevier Ltd.

This study compared violent death information reported in state-wide newspaper articles to the medical examiner reports collected for a state public health surveillance system-the National Violent Death Reporting System (NVDRS). While suicides accounted for 83% of deaths in the NVDRS database, more than three-quarters (79%) of violent deaths reported in newspaper articles were homicides. The majority of the suicide incidents were reported in 1-2 newspaper articles whereas the majority of homicide incidents were reported in 11-34 articles. For suicide incidents, the NVDRS reported more circumstances related to mental health problems while newspaper articles reported recent crisis more often. Results show that there is a mismatch in both frequency and type of information reported between a public health surveillance system (NVDRS) and newspaper reporting of violent deaths. As a result of these findings, scientists and other public health professionals may want to engage in media advocacy to provide newspaper reporters with timely and important health information related to the prevention and intervention of violent deaths in their community.

The purpose of this study was to describe the prevalence of aggressive and violent behaviors in the context of the school environment in a nationally representative sample of adolescent youth and to illustrate these patterns during 2001-2011. We analyzed data from 84,734 participants via the Youth Risk Behavior Surveillance System (YRBSS). Frequencies were visualized using heatmaps. One-way analyses of variance and corresponding post hoc tests helped to identify if differences in prevalence fluctuated significantly across all years. Rates of youth feeling unsafe in their school environment, bringing weapons to school, and engaging in physical fighting on school property continue to persist. Findings illustrated that Hispanic youth and youth classified as "other" have emerged as particularly high-risk demographic subgroups over the past decade. Peer victimization and sexual victimization continue to affect girls disproportionately. Though some variation within demographic subgroups exists, rates of aggressive and violent behaviors in the context of the school environment continue to persist. Implications for the coordinated prevention of aggressive and violent behaviors among adolescent youth are discussed and recommendations for school-based prevention efforts are identified. © 2015, American School Health Association.

The results of a literature study on the socio-economic impacts of climate change and the possibilities of violent conflicts enhanced by the greenhouse effect are presented. The socio-economic impacts are classified according to the economic sectors agriculture, forestry, fishery, energy, water, construction, transport, tourism and recreation and discussed in Chapter 2. The impacts on property, ecosystems and human well being are outlined in chapter 3. Chapter 4 deals with climate change and environmental security, and discusses the most important concepts of security and their relation to climate change. Chapter 5 deals with already existing and potential conflicts, that may be enhanced by the greenhouse effect as a result of resource scarcity, particularly related to availability of food and water. On the basis of the literature study and an analysis of research gaps propositions are made on new areas of research to be undertaken. The study emphasizes the need to further study the impact on agriculture in semi-arid zones, the impact on water availability in sensitive regions, a further analysis of the consequences of sea level rise particularly in sensitive areas and with regard to forced migration. Also further studies are required into the socio-economic impacts of changes in human health and mortality due to climate change, in relation to diseases. Special attention should be paid to migration because of environmental degradation and flooding. Extreme weather events have already been studied, but there still is a need for further insights into how extreme weather events will affect society, taking into account adaptive behaviour. Finally, in the area of socio-economic impacts, the implications of changes in ecosystems and biodiversity require further attention as these effects may be large but, at the same time, difficult to assess in economic terms. 175 refs

Objectives: The aim of the study was to describe patients’ perceptions of the possible environmental and staff factors that might contribute to their aggressive and violent behaviour after admission to a mental health facility; and to propose strategies to prevent and manage such behaviour. Research design: A qualitative, phenomenological study was utilised, in which purposefully sampled inpatients were interviewed over a six-month period. Inpatients were invited to participate if they had been admitted for at least seven days and were in touch with reality. Method: Forty inpatients in two mental health facilities in Cape Town participated in face-to-face, semi-structured interviews over a period of six months. Tesch’s descriptive method of open coding formed the framework for the data analysis and presentation of the results. Trustworthiness was ensured in accordance with the principles of credibility, confirmability, transferability and dependability. Results: Analysis of the data indicates two central categories in the factors contributing to patients’ aggressive and violent behaviour, namely, environmental factors and the attitude and behaviour of staff. Conclusion: From the perspective of the inpatients included in this study, aggressive and violent episodes are common and require intervention. Specific strategies for preventing such behaviour are proposed and it is recommended that these strategies be incorporated into the in-service training programmes of the staff of mental health facilities. These strategies could prevent, or reduce, aggressive and violent behaviour in in-patient facilities.

Full Text Available Abstract Background Most previous studies on mortality in violent offenders or victims are based on prison or hospital samples, while this study analyzed overall and cause specific mortality among violent offenders, victims, and individuals who were both offenders and victims in a general sample of 48,834 18-20 year-old men conscripted for military service in 1969/70 in Sweden. Methods Each person completed two non-anonymous questionnaires concerning family, psychological, and behavioral factors. The cohort was followed for 35 years through official registers regarding violent offenses, victimization, and mortality. The impact of violence, victimization, early risk factors and hospitalization for psychiatric diagnosis or alcohol and drug misuse during follow up on mortality was investigated using Cox proportional hazard regression analyses. Results Repeat violent offenses were associated with an eleven fold higher hazard of dying from a substance-related cause and nearly fourfold higher hazard of dying from suicide. These figures remained significantly elevated also in multivariate analyses, with a 3.03 and 2.39 hazard ratio (HR, respectively. Participants with experience of violence and inpatient care for substance abuse or psychiatric disorder had about a two to threefold higher risk of dying compared to participants with no substance use or psychiatric disorder. Conclusions Violent offending and being victimized are associated with excess mortality and a risk of dying from an alcohol or drug-related cause or suicide. Consequently, prevention of violent behavior might have an effect on overall mortality and suicide rates. Prevention of alcohol and drug use is also warranted.

The longitudinal relationship between attention deficit hyperactivity disorder (ADHD) and violent criminality has been extensively documented, while long-term effects of autism spectrum disorders (ASDs), tic disorders (TDs), and obsessive compulsive disorder (OCD) on criminality have been scarcely studied. Using population-based registers of all child and adolescent mental health services in Stockholm, we identified 3,391 children, born 1984-1994, with neurodevelopmental disorders, and compared their risk for subsequent violent criminality with matched controls. Individuals with ADHD or TDs were at elevated risk of committing violent crimes, no such association could be seen for ASDs or OCD. ADHD and TDs are risk factors for subsequent violent criminality, while ASDs and OCD are not associated with violent criminality.
Full Text Available The literature provides some evidence that the use of violent video games increases the risk for young people to develop aggressive cognitions and even behaviors. We aimed to verify whether exposure to violent video games is linked to problems of aggression in a sample of Italian children. Four questionnaires were administered to 346 children between 7 and 14 years of age, attending primary and secondary schools in Northern Italy. Variables measured were externalization, quality of interpersonal relationships, aggression, quality of coping strategies, and parental stress. Participants who preferred violent games showed higher scores for externalization and aggression. The use of violent video games and age were linked to higher levels of aggression, coping strategies, and the habitual video game weekly consumption of participants. Our data confirm the role of violent video games as risk factors for problems of aggressive behavior and of externalization in childhood and early adolescence.

The LEGO company has become the world's largest toy manufacturer. Our study investigates if the LEGO company's products have become more violent over time. First, we analyzed the frequency of weapon bricks in LEGO sets. Their use has significantly increased. Second, we empirically investigated the perceived violence in the LEGO product catalogs from the years 1978-2014. Our results show that the violence of the depicted products has increased significantly over time. The LEGO Company's products are not as innocent as they used to be.

Historically, the American Academy of Psychiatry and the Law (AAPL) has not engaged in debates on public policy. In its unique position at the interface of law and medicine, AAPL is able to make important contributions to social policy involving management of violent youths. In the 1990s, increasing rates of violence among adolescents spawned a new era of research into the causes and correlates of violence in youths. The resultant data on risk factors have provided opportunities for establishing empirical assessments and risk-focused treatment programs. Community treatment programs that demonstrate a moderate effect in reducing violence have renewed optimism about the benefit of treatment over punishment. The ongoing development of methodology to assess risk for violence presents opportunities for advancement of rehabilitation. Current social policies that limit the ability to provide treatment and rehabilitation in juvenile settings should be challenged by organized psychiatry.

Patients with extreme agitation, delirium, violent behavior or acute psychosis are frequently evaluated in the emergency departments of general hospitals. However, the traditional infrequency of this type of situation in pediatric emergency services can lead to a certain lack of foresight and efficiency in the initial management of these patients. Because of the current known increase of psychosocial disorders in pediatric emergencies, new pharmacological treatments for juvenile psychotic processes, and particularly the lack of compliance with these treatments, as well as the earlier consumption of ever more varied illicit drugs among young people, the frequency and diversity of this kind of disorder is on the increase. The treatment of agitation, aggression and violence begins with successful management of the acute episode, followed by strategies designed to reduce the intensity and frequency of subsequent episodes. The key to safety is early intervention to prevent progression from agitation to aggression and violence. Consequently, urgent measures designed to inhibit agitation should be adopted without delay by the staff initially dealing with the patient, usually in the emergency unit. Patients with psychomotor agitation disorder (PMAD) may require emergency physical and/or chemical restraints for their own safety and that of the healthcare provider in order to prevent harmful clinical sequelae and to expedite medical evaluation to determine the cause. However, the risks of restraint measures must be weighed against the benefits in each case. This review aims to present the emergency measures to be taken in children with PMAD. The distinct etiological situations and criteria for the choice of drugs for chemical restraint in each situation, as well as the complications associated with certain drugs, are discussed. It is advisable, therefore, that health professionals become familiar with the distinct pharmacological options.

To analyze the association between violent behavior in adolescents and parent-child cohabitation. A population-based cross-sectional study with multiple-stage sampling was performed in the urban area of the city of Pelotas, Southern Brazil, in 2002. A total of 960 adolescents were interviewed using a self-applied questionnaire. The dependent variables (use of weapons and involvement in fights in the previous year were reported by adolescents) and the independent variable (parent-child cohabitation) were analyzed with the chi-square test and prevalence ratios, adjusted for age, sex, socioeconomic level and reporting of alcohol, tobacco or illicit drug use, both recently and throughout life. Involvement in fights in the previous year was reported by 23% of participants and use of weapons by 9.6%. Prevalence ratios of occurrence of such behaviors was 1.38 (95% CI: 0.71; 2.68, p=0.34) for involvement in fights and 1.68 (95% CI: 1.06; 2.67, p=0.03) for use of weapons, including "adolescents living with the father, mother or both" as reference. Parent-child cohabitation must be considered in policies aimed at preventing the use of weapons by children and adolescents, although it is recommended that care should be taken not to stigmatize children and adolescents who do not live with their fathers and mothers.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), Task Force has recently rejected the proposal to include coercive paraphilia as an official diagnosis, reaffirming that rape is a crime and not a mental disorder. We hope this will discourage what has been the inappropriate practice of giving rapists the made-up diagnosis of paraphilia, NOS, nonconsent, to facilitate their psychiatric commitment under sexually violent predator (SVP) statutes. Losing the paraphilia, NOS, option has tempted some SVP evaluators to overdiagnose sexual sadism, which is an official DSM mental disorder. To prevent this improper application and to clarify those rare instances in which this diagnosis might apply, we present a brief review of the research on sexual sadism; an annotation of its definitions that have been included in the DSM since the Third Edition, published in 1980, and in the International Classification of Diseases, Tenth Edition (ICD-10); and a two-step process for making a diagnostic decision. Rape and sexual sadism have in common violence, cruelty, and a callous indifference on the part of the perpetrator to the suffering of the victim, but they differ markedly in motivation. Rapists use violence to enforce the victim's cooperation, to express aggression, or both. In contrast, in sexual sadism, the violence, domination, and infliction of pain and humiliation are a preferred or necessary precondition for sexual arousal. Only a small proportion of rapists qualify for the diagnosis of sexual sadism.
Full Text Available Aggression and violence have been a customary part of life that mankind has had to live with from the beginning of time; it has been accepted by society even though it expresses endless negativity. Aggression and violence can find a place in sports events and football games because of the social problems of the audience watching the competitions or games, which sometimes fall into the category of hooliganism. Turkey is one of the countries that should consider this problem to be a serious social problem. Even during 2014 and 2015, a relatively short period of time, there were significant hazardous acts committed by hooligans. In February 2014, one supporter was killed after a game between Liverpool and Arsenal in England; in March 2014, a game between Trabzonspor and Fenerbahce was left half-finished because of violent acts in the stadium that caused players in the pitch to believe that they could not leave stadium alive, although they finally left after a few hours; in another incident in March 2014, one supporter was killed after a game between Helsingborg and Djugarden in Sweden; in November 2014, one supporter was killed and 14 supporters were injured before the game between Atletico Madrid and Deportivo in Spain. These are all examples of aggression, violence, and hooliganism in football. This paper aims to discuss aggression, violence, and hooliganism in football, especially in recent years, and investigate what can be done to prevent these acts from occurring again in the future by examining them in hindsight.

Background and Purpose: We investigated the clinical and criminal characteristics of patients with epilepsy who had committed violent crimes in order to understand the mechanism of violence and to prevent future criminal activity. Methods: We reviewed medical and legal reports of criminals with epilepsy who were incarcerated in the Korean National Forensic Hospital between October 2007 and September 2008. Results: Of 761 criminals admitted to the National Forensic Hospital, 17 patients (2.2%) were diagnosed with epilepsy. All of them had localization-related epilepsy, and no patient reported an overt seizure attack around the time of a crime. Psychosis was present in eight patients, and seven patients were in a drunken state at the time of the crimes. There was a positive correlation between the patients’ age at their first crime and their intelligence quotient score. Conclusions: These results suggest that most violent crimes take place during interictal periods, and diverse medical conditions, including inebriation, psychosis, and low intelligence, are associated with violent crimes among epileptic patients.

Although some view the ownership of firearms as a deterrent to crime, the relationship between population-level firearm ownership rates and violent criminal perpetration is unclear. The purpose of this study is to test the association between state-level firearm ownership and violent crime. State-level rates of household firearm ownership and annual rates of criminal acts from 2001, 2002, and 2004 were analyzed in 2014. Firearm ownership rates were taken from a national survey and crime data were taken from the Federal Bureau of Investigation Uniform Crime Reports. Rates of criminal behavior were estimated as a function of household gun ownership using negative binomial regression models, controlling for several demographic factors. Higher levels of firearm ownership were associated with higher levels of firearm assault and firearm robbery. There was also a significant association between firearm ownership and firearm homicide, as well as overall homicide. The findings do not support the hypothesis that higher population firearm ownership rates reduce firearm-associated criminal perpetration. On the contrary, evidence shows that states with higher levels of firearm ownership have an increased risk for violent crimes perpetrated with a firearm. Public health stakeholders should consider the outcomes associated with private firearm ownership. Copyright © 2015 American Journal of Preventive Medicine. Published by Elsevier Inc.

This article presents a brief overview of existing research on the effects of exposure to violent video games. An updated meta-analysis reveals that exposure to violent video games is significantly linked to increases in aggressive behaviour, aggressive cognition, aggressive affect, and cardiovascular arousal, and to decreases in helping behaviour. Experimental studies reveal this linkage to be causal. Correlational studies reveal a linkage to serious, real-world types of aggression. Methodologically weaker studies yielded smaller effect sizes than methodologically stronger studies, suggesting that previous meta-analytic studies of violent video games underestimate the true magnitude of observed deleterious effects on behaviour, cognition, and affect.

Although interventions exist to reduce violent crime, optimal implementation requires accurate targeting. We report the results of an attempt to develop an actuarial model using machine learning methods to predict future violent crimes among US Army soldiers. A consolidated administrative database for all 975 057 soldiers in the US Army in 2004-2009 was created in the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS). Of these soldiers, 5771 committed a first founded major physical violent crime (murder-manslaughter, kidnapping, aggravated arson, aggravated assault, robbery) over that time period. Temporally prior administrative records measuring socio-demographic, Army career, criminal justice, medical/pharmacy, and contextual variables were used to build an actuarial model for these crimes separately among men and women using machine learning methods (cross-validated stepwise regression, random forests, penalized regressions). The model was then validated in an independent 2011-2013 sample. Key predictors were indicators of disadvantaged social/socioeconomic status, early career stage, prior crime, and mental disorder treatment. Area under the receiver-operating characteristic curve was 0.80-0.82 in 2004-2009 and 0.77 in the 2011-2013 validation sample. Of all administratively recorded crimes, 36.2-33.1% (male-female) were committed by the 5% of soldiers having the highest predicted risk in 2004-2009 and an even higher proportion (50.5%) in the 2011-2013 validation sample. Although these results suggest that the models could be used to target soldiers at high risk of violent crime perpetration for preventive interventions, final implementation decisions would require further validation and weighing of predicted effectiveness against intervention costs and competing risks.

Epidemiological studies have shown the adverse neuro-behavioral health effects of lead exposure among children, in particular. However, there is lack evidence in this regard from developing countries. The main aim of this study was to assess the association between blood lead levels (BLLs) during early adolescence and violent behavior in late adolescence. Our study sample from the Birth to Twenty Plus cohort in Soweto-Johannesburg, South Africa included 1332 study participants (684 females). BLLs were measured using blood samples collected at age 13years. Violent behavior was evaluated using data collected at ages 15 to 16years using the Youth Self Report questionnaire. First, bivariate analysis was used to examine data for an association between lead exposure in early adolescence and violent behavior items during late adolescence. Principal Component Analysis (PCA) was used for dimensionality reduction and six violent behavior components were derived. Data were further analyzed for an association between BLLs at age 13years and violent behavior using PCA derived components; to determine the specific type(s) of violent behavior associated with lead exposure. Median whole BLLs were 5.6μg/dL (padolescence associated with childhood lead exposure. They highlight the urgent need for preventive measures against lead exposure among children in low or middle income countries such as South Africa. Copyright © 2017 Elsevier Ltd. All rights reserved.

This review makes four contributions to the sociological study of sports fans, alcohol use, and violent behavior. First, this article focuses explicitly on the relationship between alcohol use and violent behavior among sports fans. This is a worldwide social problem, yet it is quite understudied. Second, this article synthesizes the fragmented literature on alcohol use and violent behavior among sports fans. Third, this article identifies four broad sets of risk factors-sociocultural, event/venue, police, and crowd-that appear to be closely related to violent behavior among sports fans. Finally, to help explain the possible correlation between alcohol and violence among sports fans, this article draws upon the key understandings from the literature on alcohol and violence in wider society. The article concludes with suggestions for future research. © The Author(s) 2016.

Forty-three subjects from secondary school took part in a correlation study investigating the nature of cognitive processes involved in the presentation of violent behaviour. Measures of violence were scores on "aggression items" of a self-report questionnaire. The experimental procedure involved binocular tachistoscopic presentation of neutral and violent slide pairs. Descriptions of the composite stimuli were scored for violent content. The main finding was that subjects who had reported more involvement in violent acts also reported seeing more violence in the stimulus array. This association held irrespective of age, IQ, socio-economic status and starting mood. It is argued that these findings indicate a perceptual, rather than a response, bias. A role for this bias as a possible maintaining condition in the presentation of aggressive behaviour is presented. The implications of the present findings for interventions with young people are discussed. It is suggested that cognitive techniques may prove more effective than traditional behavioural programmes.

The Antisocial Personality Questionnaire developed by Blackburn and Fawcett (1999) has shown adequate reliability and validity in studies of male offenders interned in psychiatric hospitals. This paper provides data on the APQ collected from a sample of offenders (males and females) without any diagnosed mental illness. The sample was made up of 216 offenders (108 males and 108 females) confined in Spanish prisons. We analyzed the psychometric properties of the instrument and we also examined differences in personality as a function of gender and type of crime (violent vs. non-violent). Results support the reliability of the APQ scales as well as the structure proposed by Blackburn. Additionally, we selected items that discriminate between offenders convicted for violent and non-violent crimes; when these items are factorized, a three-factor structure emerges, resembling Eysenck's model.

The Violent Experiences Questionnaire-Revised (VEQ-R) is a brief retrospective self-report inventory which provides estimates of annual frequencies of childhood physical abuse, sibling physical abuse, exposure to parental violence, peer bullying, and corporal punishment as they were experienced from ages 5 to 16. The VEQ-R indices rely on a frequency metric that estimates the number of days on average per year a specified class of behavior occurred over a 12year retrospective period. All scores range from a frequency of 0 to a high of 104. Scale normative data was generated from both a college (N=1266) and national (N=1290) sample to expand the research applicability of this relatively new inventory. Subscales were added to estimate the frequency of victimization during childhood, the pre-teen years, and adolescence. Four "hostility" component indices were derived from perpetrator source (parent, sibling, peer, or domestic). Thresholds were established to for High, Moderate, Low, and No Risk classifications. Subscales dimensions were found to have both adequate internal and temporal consistency. Evidence of concurrent and discriminant validity was generated using the Parent-Child Conflict Tactics Scale-Short-Form © , LONGSCAN Physical Abuse Self-Report scale, and Physical Punishment scale of the Assessing Environments III inventory.

During the formation of stellar systems such as globular clusters, low-mass subcondensations which eventually form stars must retain a geometric size throughout the collapse process that is small compared to the characteristic distance separating them. If the local velocity dispersion of the subcondensations is small, the overall dimension of the system can decrease substantially before reaching a dynamical equilibrium state. The maximum collapse factor is deduced by examining the growth of the velocity dispersion and the spread in arrival times at the origin caused by local and global fluctuations. It is shown, analytically as well as in a series of N-body simulations, that the maximum reduction in the characteristic dimension of a system of N fragments with an initial homogeneous distribution subject to N exp 1/2 fluctuations is proportional to N exp 1/3. Direct physical collisions between low-mass subcondensations are therefore unlikely to occur in protoglobular clusters. The results are discussed in the context of fragmentation and violent relaxation. 29 references.

The prevailing view of planet formation depicts accumulation of progressively larger objects, culminating in accretionary impacts between Moon- to Mars-sized protoplanets. Cosmochemists have found evidence in chondritic meteorites for such violent events, and the Moon is thought to have involved a huge impact between a Mars-sized object and the still-growing proto-Earth. Now we may have evidence for a large impact during planet formation around another star. Carey Lisse (Applied Physics Lab of the Johns Hopkins University, Baltimore) and colleagues from the Space Telescope Science Institute (Baltimore), the University of Cambridge (UK), the Open University (Milton Keyes, UK), the University of Georgia (Athens, GA), Jet Propulsion Lab (Pasadena, CA), and the University of Rochester (New York) analyzed infrared spectra obtained by the Spitzer Space Telescope. They found a prominent peak in the spectrum at 9.3 micrometers, and two smaller ones at slightly lower and higher wavelengths. These peaks are consistent with the presence of SiO gas, a product expected to be produced by a highly energetic impact. The spectral measurements also allowed Lisse and his colleagues to estimate the size of the dust and they found that there is an abundance of micrometer-sized dust grains. This argues for a fresh source of fine material during the past 0.1 million years. That source may have been an impact between two protoplanets surrounding this young star.

The literature provides some evidence that the use of violent video games increases the risk for young people to develop aggressive cognitions and even behaviors. We aimed to verify whether exposure to violent video games is linked to problems of aggression in a sample of Italian children. Four questionnaires were administered to 346 children between 7 and 14 years of age, attending primary and secondary schools in Nor...

We hypothesize the failure of government to protect the rights of individuals from violence committed by youths has led to the formation of youth gangs as protective agencies. Our theory predicts an opposite direction of causality between gang activity and violent crime than is widely accepted. While areas with more gang activity also have more violence, our results suggest gangs form as protection agencies precisely in areas with high violent crime rates. While gangs, like governments, use v...

Although selective serotonin reuptake inhibitors (SSRIs) are widely prescribed, associations with violence are uncertain. From Swedish national registers we extracted information on 856,493 individuals who were prescribed SSRIs, and subsequent violent crimes during 2006 through 2009. We used stratified Cox regression analyses to compare the rate of violent crime while individuals were prescribed these medications with the rate in the same individuals while not receiving medication. Adjustments were made for other psychotropic medications. Information on all medications was extracted from the Swedish Prescribed Drug Register, with complete national data on all dispensed medications. Information on violent crime convictions was extracted from the Swedish national crime register. Using within-individual models, there was an overall association between SSRIs and violent crime convictions (hazard ratio [HR] = 1.19, 95% CI 1.08-1.32, p crime convictions for individuals aged 15 to 24 y (HR = 1.43, 95% CI 1.19-1.73, p crime arrests with preliminary investigations (HR = 1.28, 95% CI 1.16-1.41, p non-violent crime convictions (HR = 1.22, 95% CI 1.10-1.34, p non-violent crime arrests (HR = 1.13, 95% CI 1.07-1.20, p crime convictions for males aged 15 to 24 y (HR = 1.40, 95% CI 1.13-1.73, p = 0.002) and females aged 15 to 24 y (HR = 1.75, 95% CI 1.08-2.84, p = 0.023). However, there were no significant associations in those aged 25 y or older. One important limitation is that we were unable to fully account for time-varying factors. The association between SSRIs and violent crime convictions and violent crime arrests varied by age group. The increased risk we found in young people needs validation in other studies.

Predictability of dangerousness in association with mental disorders remains elusive, outside of a few relatively well-established risk factors for the prognostication of violence, such as male sex, the presence of a psychotic disorder, and comorbid substance abuse. In clinical practice, inquiry into the presence of aggressive or violent ideation, in the form of ideas of homicide or suicide, is part of a standard mental status examination. Nonetheless, fantasy life, when it concerns harm toward others, may not be as reliable an indicator of imminent danger as it may be in the case of self-harm. Five cases of young Italian men with Asperger syndrome and recurrent and extremely violent femicide fantasies are presented. While there is no direct correlation between autism spectrum conditions and violence, as other humans, persons with an autistic condition are capable of committing crimes, including homicide. All five had in common a number of characteristics and behaviors felt to be pathoplastic: All had been bullied, all had been romantically rejected, all were long-standing First Person Shooter (FPS) game players, and all were avid violent pornography consumers. The potential for an actual neurocognitive impact of violent video games, well documented in the literature, and its combination with personal life history and chronic habituation following long-standing violent pornography use is discussed in the context of social and emotional vulnerabilities. While aggressive fantasies cannot and should not be underestimated, in countries where duty to protect legislation does not exist, a clinical approach is imperative, as, incidentally, should be anywhere.

Objective We aimed to assess the risk factors associated with homicidal behaviour in male patients diagnosed with schizophrenia. Methods In a period of 1 year, male schizophrenia cases between 18-65 years of age (n = 210) were included. The clinical evaluation included the Positive and Negative Syndrome Scale (PANSS) and Overt Aggression Scale (OAS). The patients were divided into three groups in terms of violent behaviour history: (1) homicide group (n = 30), (2) a violent act resulting in serious injury (n = 71), (3) control group (patients without a history of a violent act) (n = 109). Results Lower level of education, rural residence, being unemployed and living alone were found to be significantly more common in patients who had committed a violent act compared to the schizophrenia patients in the control group. In order to explore the predictive value of several factors associated with violent behaviour, a logistic regression model was used, and variables (shorter duration of education, living alone, and lack of insight) significantly predicted the presence of violent behaviour (murder and/or injury) (χ(2)=31.78, df = 12, p = 0.001). Conclusions In order to be able to determine causality of homicidal acts in schizophrenia patients, our significant findings between homicidal violence, non-homicidal violence and the control group would merit further attention and exploration in further studies.

Full Text Available This article is about the effect of local tailored interventions to counter (violent extremism, and therefore contributes to the academic and policy debates. It focusses on local, professional perspectives on person-specific interventions utilising a Dutch case study as the basis. The interventions are part of the wider-ranging counter terrorism policy that entails (local measures that are deployed in relation to designated high-risk individuals and groups. By reviewing policy documents and conducting semi-structured interviews, the exploratory study concludes that the key factors for a hand-tailored intervention are a solid network, expert knowledge to assess potential signs of extremist ideology, an awareness of not having too many concurrent measures, good inter-institutional cooperation and information-sharing. The professionals involved felt that person-specific interventions have contributed to reducing the threat of religious extremism in the Netherlands. Nonetheless, municipal officials and security agents emphasised the importance of setting realistic goals and a focus on preventive rather than repressive measures. Furthermore, despite the central role that municipal actors play, they run up against problems such as cooperation within the security and care sector. National entities appear to emphasize information-gathering and monitoring more than community-focused cooperation. Thereby questioning whether, on the national level, local professionals are perceived as playing a key role in dealing with extremism.

International audience; Previous research has shown that media violence exposure can cause desensitization to violence, which in theory can increase aggression. However, no study to date has demonstrated this association. In the present experiment, participants played a violent or nonviolent video game, viewed violent and nonviolent photos while their brain activity was measured, and then gave an ostensible opponent unpleasant noise blasts. Participants low in previous exposure to video game ...

We conducted a systematic review to critically appraise and synthesize literature on the effectiveness of work disability prevention (WDP) interventions in workers with neck pain, whiplash-associated disorders (WAD), or upper extremity disorders. We searched electronic databases from 1990 to 2012. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Scientifically admissible studies were summarized and synthesized following best-evidence synthesis methodology. Of the 6,359 articles retrieved, 16 randomized controlled trials were eligible for critical appraisal and five were admissible. We found that a return-to-work coordination program (including workplace-based work hardening) was superior to clinic-based work hardening for persistent rotator cuff tendinitis. Workplace high-intensity strength training and workplace advice had similar outcomes for neck and shoulder pain. Mensendieck/Cesar postural exercises and strength and fitness exercises had similar outcomes for non-specific work-related upper limb complaints. Adding a brief job stress education program to a workplace ergonomic intervention was not beneficial for persistent upper extremity symptoms. Adding computer-prompted work breaks to ergonomic adjustments and workplace education benefited workers' recovery from recent work-related neck and upper extremity complaints. At present, no firm conclusions can be drawn regarding the effectiveness of WDP interventions for managing neck pain, WAD, and upper extremity disorders. Our review suggests a return-to-work coordination program is more effective than clinic-based work hardening. Also, adding computer-prompted breaks to ergonomic and workplace interventions benefits workers' recovery. The current quality of evidence does not allow for a definitive evaluation of the effectiveness of ergonomic interventions.

Mutations in mitochondrial DNA (mtDNA) have been found to be associated with sensorineural hearing loss. We report here the clinical, genetic, and molecular characterization of 16 Chinese pedigrees (a total of 246 matrilineal relatives) with aminoglycoside-induced impairment. Clinical evaluation revealed the variable phenotype of hearing impairment including audiometric configuration in these subjects, although these subjects share some common features: being bilateral and sensorineural hearing impairment. Strikingly, these Chinese pedigrees exhibited extremely low penetrance of hearing loss, ranging from 4% to 18%, with an average of 8%. In particular, nineteen of 246 matrilineal relatives in these pedigrees had aminoglycoside-induced hearing loss. Mutational analysis of the mtDNA in these pedigrees showed the presence of homoplasmic 12S rRNA A1555G mutation, which has been associated with hearing impairment in many families worldwide. The extremely low penetrance of hearing loss in these Chinese families carrying the A1555G mutation strongly supports the notion that the A1555G mutation itself is not sufficient to produce the clinical phenotype. Children carrying the A1555G mutation are susceptible to the exposure of aminoglycosides, thereby inducing or worsening hearing impairment, as in the case of these Chinese families. Using those genetic and molecular approaches, we are able to diagnose whether children carry the ototoxic mtDNA mutation. Therefore, these data have been providing valuable information and technology to predict which individuals are at risk for ototoxicity, to improve the safety of aminoglycoside therapy, and eventually to decrease the incidence of deafness
Full Text Available Injury related to violent acts is a problem in every society. Although some authors have examined the geography of violent crime, few have focused on the spatio-temporal patterns of violent injury and none have used an ambulance dataset to explore the spatial characteristics of injury. The purpose of this study was to describe the combined spatial and temporal characteristics of violent injury in a large urban centre.Using a geomatics framework and geographic information systems software, we studied 4,587 ambulance dispatches and 10,693 emergency room admissions for violent injury occurrences among adults (aged 18-64 in Toronto, Canada, during 2002 and 2004, using population-based datasets. We created kernel density and choropleth maps for 24-hour periods and four-hour daily time periods and compared location of ambulance dispatches and patient residences with local land use and socioeconomic characteristics. We used multivariate regressions to control for confounding factors. We found the locations of violent injury and the residence locations of those injured were both closely related to each other and clearly clustered in certain parts of the city characterised by high numbers of bars, social housing units, and homeless shelters, as well as lower household incomes. The night and early morning showed a distinctive peak in injuries and a shift in the location of injuries to a "nightlife" district. The locational pattern of patient residences remained unchanged during those times.Our results demonstrate that there is a distinctive spatio-temporal pattern in violent injury reflected in the ambulance data. People injured in this urban centre more commonly live in areas of social deprivation. During the day, locations of injury and locations of residences are similar. However, later at night, the injury location of highest density shifts to a "nightlife" district, whereas the residence locations of those most at risk of injury do not change.

High violent mortality rate in Russia and its profound fluctuation over recent decades have attracted considerable interest. A mounting body of evidence points to the binge drinking pattern as a potentially important contributor to the violent mortality crisis in Russia. In line with this evidence, we assume that higher level of vodka consumption in conjunction with binge drinking pattern results in close aggregate-level association between vodka sales and violent mortality rates in Russia. To test this hypothesis, trends in beverage-specific alcohol sales per capita and mortality rates from external causes in Russia between 1980 and 2005 were analyzed by means of ARIMA time-series analysis. Results of the analysis indicate that violent mortality rates tend to be more responsive to change in vodka sales per capita than to change in total level of alcohol sales. The analysis suggests that a 1-litre increase in vodka sales per capita would result in a 5% increase in violent mortality rate, an 11.3% increase in accidents and injuries mortality rate, a 9.2% increase in suicide rate, a 12.5% increase in homicide rate, and a 21.9% increase in fatal alcohol poisoning rate. The outcomes of this study provide support for the hypothesis that alcohol played a crucial role in the fluctuation in violent mortality rate in Russia in recent decades. Assuming that drinking vodka is usually associated with intoxication episodes, these findings provide additional evidence that the binge drinking pattern is an important determinant of the violent mortality crisis in Russia.

Prematurity and the associated risk for bronchopulmonary dysplasia (BPD) remain a significant threat to extremely low birth weight (ELBW) infants. Vitamin A has been considered a therapeutic alternative in reducing the rate of BPD and mortality. To investigate whether early postnatal, additional high-dose oral vitamin A supplementation for 28 days is more efficient in reducing BPD or death in ELBW infants than placebo treatment. This is a multicenter, double-blind RCT comparing postnatal high-dose oral vitamin A supplementation (5,000 IU vitamin A/kg/day vs. placebo) for 28 days in ELBW neonates requiring mechanical ventilation, noninvasive ventilatory support or supplemental oxygen at 24 h of age. The primary end point is the proportion of children who died before 36 weeks' gestational age or developed moderate or severe BPD. BPD is defined as the need for supplemental oxygen to maintain SaO2 of ≥92% at rest at 36 weeks' postmenstrual age (PMA). Clinical secondary end points include the following: BPD (including mild form), intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity, necrotizing enterocolitis, total number of days of mechanical ventilation and oxygen supplementation, and safety and tolerability of high-dose vitamin A supplementation. The results of the NeoVitaA trial will provide robust data with regard to the efficacy of high-dose oral vitamin A supplementation in reducing the incidence of BPD or death at 36 weeks' PMA in ELBW infants. © 2014 S.

Although opioid maintenance treatment (OMT) has been found to reduce crime, less is known about its associations with violent crime. This study investigates changes in violent crime convictions prior to, during, and after OMT, and examines the relationship between violent crime convictions prior to OMT with the risk of violent and non-violent crime convictions during treatment. The cohort comprised all who started OMT (n=3221) in Norway between 1997 and 2003. Treatment data were cross linked with the national Crime Registry. Convictions for violent crime 3 years prior to, during, and after treatment were studied. Violent crime rates were significantly reduced during OMT compared with before treatment, for both men and women. The rate of convictions for violent crime during OMT was halved amongst those who remained in treatment. The reduction was less pronounced for those who left treatment: for this group, the rate of violent convictions after OMT was higher than before treatment. The risk of convictions for violent and non-violent crime during OMT was highest for those with violent convictions prior to treatment. Violent crime is reduced during OMT. Screening for violent behaviour and violence risk assessment should be implemented in the treatment system. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

It is controversial if global warming will result into increased crime and conflict rate, and no causal neurobiological mechanisms have been proposed for the putative association between ambient temperature and aggressive behavior. This study shows that during 1996-2013, ambient temperature explained 10% of variance in the violent crime rate in Finland, corresponding to a 1.7% increase/degree centigrade. Ambient temperature also correlated with a one month delay in circannual changes in peripheral serotonin transporter density among both offenders and healthy control subjects, which itself correlated strongly with the monthly violent crime rate. This suggests that rise in temperature modulates serotonergic transmission which may increase impulsivity and general human activity level, resulting into increase in social interaction and risk of violent incidents. Together, these results suggest that the effect of ambient temperature on occurrence of violent crime is partly mediated through the serotonergic system, and that a 2 °C increase in average temperatures would increase violent crime rates by more than 3% in non-tropical and non-subtropical areas, if other contributing factors remained constant.

Most studies on the impact of playing violent video games on mental health have focused on aggression. Relatively few studies have examined the relationship between playing violent video games and depression, especially among preadolescent youth. In this study, we investigated whether daily violent video game playing over the past year is associated with a greater number of depressive symptoms among preadolescent youth, after controlling for several well-known correlates of depression among youth. We analyzed cross-sectional data collected from 5,147 fifth-grade students and their primary caregivers who participated in Wave I (2004-2006) of Healthy Passages, a community-based longitudinal study conducted in three U.S. cities. Linear regression was conducted to determine the association between violent video game exposure and number of depressive symptoms, while controlling for gender, race/ethnicity, peer victimization, witnessing violence, being threatened with violence, aggression, family structure, and household income level. We found that students who reported playing high-violence video games for ≥2 hours per day had significantly more depressive symptoms than those who reported playing low-violence video games for violent video games and number of depressive symptoms among preadolescent youth. More research is needed to examine this association and, if confirmed, to investigate its causality, persistence over time, underlying mechanisms, and clinical implications.

This population-based cross-sectional survey examined the association between exposure to violent online games and cyberbullying and victimization in adolescents recruited from two large cities utilizing a stratified two-stage random cluster sampling technique. Cyberbullying and victimization were assessed by the E-victimization and E-bullying scales validated in a previous study. Exposure to violent online games was measured by self-nomination of the degree of violent content in the games played. Results indicated that the majority (74.3 percent) of respondents did not experience any cyberbullying or victimization in the last 7 days before the survey, 14.4 percent reported to be victimized via cyberspace, 2.9 percent admitted that they had bullied others, and 8.4 percent reported to be both perpetrators- and- victims. One hundred and eighty seven (15.3 percent) considered games they were playing were of moderate to severe violence. Students who had been involved in cyberbullying as well as being victimized were two times as likely to have been exposed to violent online games, and nearly four times as likely for those involved in bullying others. Exposure to violent online games was associated with being a perpetrator as well as a perpetrator-and-victim of cyberbullying. Parents and clinicians need to be aware of the potential harm of these exposures. The policy implications of results were also discussed.

The aim of this study was to identify prevalence and factors associated with violent behavior among adolescents in Aracaju and Metropolitan region. The study included 2207 adolescents (16.03 ± 1.08 years old) enrolled in high schools of the State Public Network. Violent behavior was identified from question 14 of the YRBS-2007 questionnaire with responses categorized as “never” and “one or more times.” Higher prevalence in males in relation to risk factors for adoption of violent behavior was found: cigarette consumption (7.3%), alcohol consumption (39.1%), and marijuana use (3.4%). Data analysis used descriptive statistics and logistic regression with hierarchical model at two levels: (a) sociodemographic variables and (b) behavioral variables. For both sexes, association between violent behavior and cigarette smoking (OR = 3.77, CI 95% = 2.06–6.92 and OR = 1.99, CI 95% = 1.04 to 3.81, male and female, resp.) and alcohol consumption (OR = 3.38, CI 95% = 2.22 to 5.16 and OR = 1.83, CI 95% = 1.28 to 2.63, male and female, resp.) was verified. It was concluded that violent behavior is associated with the consumption of alcoholic beverages and cigarettes among adolescents. PMID:25548796

For many terrorist organizations, also known as violent extremist organizations (VEOs), their ability to perpetuate violence is often contingent upon successful recruitment and selection of organizational members. Although academic work on terrorist recruitment and selection has improved in recent years, researchers have generally focused more heavily on aspects of radicalization rather than organization attraction and entry. Moreover, a number of terrorism scholars have lamented the lack of conceptual frameworks with which to interpret and extend findings linked to recruitment and selection, specifically. In light of these difficulties, we propose that considering literature bases outside of terrorism may be useful in extending lines of inquiry and offering alternative ways of thinking about how terrorist organizations operate. Specifically, we draw on Industrial and Organizational Psychology, Human Resource Management, and Organizational Behavior literature bases to offer alternative and extended modes of thought on terrorist recruitment and selection. In doing so, we believe both terrorism and more traditional organizational scholars can make substantive and novel contributions to future investigations of increasingly pressing issues surrounding violent extremism.

To assess the relationship of breakfast intake with psychiatric distress and violent behaviors among Iranian children and adolescents. This national survey was conducted among 14,880 students, aged 6-18 y. They were selected by stratified multistage sampling method from urban and rural areas of 30 provinces of Iran. Breakfast intake, psychiatric distress, and violent behaviors were assessed by a questionnaire prepared based on the Global school-based student health survey of the World Health Organization. The data were analyzed by the STATA package. The participation rate was 90.6 %. The percentage of psychiatric distress among breakfast skippers, semi-skippers and non-skippers was 13.4-50.4, 10.1-41.9, and 7.0-33.3 % respectively. The prevalence of psychiatric distress was significantly higher among breakfast skippers than semi-skippers and non-skippers (P value breakfast skippers to non-skippers. The prevalence of violent behaviors was significantly higher among breakfast skippers than non-skippers. Students who skipped breakfast reported to be more victimized (29.2 % vs. 26.7 %, respectively, P = 0.04), bullied (21.0 % vs. 16.2 %, respectively, P breakfast were less likely to experience mental health disorders and violent behavior. Adhering to a regular and balanced diet, besides the awareness of parents on the importance of breakfast eating, may be an appropriate approach for preventing mental health problems and violent behavior in children and adolescents.
Full Text Available Intensifying global dynamics of wildlife crime are rapidly reshaping conservation politics, practices and geographies. Most pronounced are the manifold violent responses to wildlife crime, including direct lethal action and increasing anticipatory action to prevent these crimes from happening in the first place. This paper reflects on these dynamics in relation to recent literature that employs Foucault's concept of biopower to understand the governance of increasingly precarious human and non-human life. Building on Brian Massumi's exposition of ontopower – an 'environmental power' that “alters the life environment's conditions of emergence” – I explore whether we are seeing a move from bio- to ontopower where the imperative is less the construction of systemic forms of governmentality to ensure life's ‘optimisation’ than on processually pre-empting incipient tendencies towards unknown but certain future threats to life. Phrased differently, ontopower focuses on how to prevent nature's destruction in the future through pre-emptive measures in the present. Drawing on empirical research on violent responses to rhino poaching in South Africa, the paper argues that we are seeing the uneven emergence of new geographies of conservation based on ontopower. It concludes by speculating whether conservation's insecurity is turning into its pre-emptive other by making (green war necessary for non-human life's survival.

Information on the organization of interaction between different services responsible for restoration works, sanitary cleaning, disinfection under the conditions of the emergency situation is presented. The activity of the sanitary and epidemiological services in the areas in the Republic of North Ossetia-Alania, affected by high flood, is described. Measures aimed at the epidemiological surveillance of acute enteric infections, the control of the quality of drinking water and foodstuffs, the bacteriological study of material samples taken from humans, vaccinal and phage prophylaxis have taken an important place in the work of the institutions of sanitary and epidemiological surveillance. As the result of all these measures the sanitary and epidemiological service has managed to prevent the aggravation of the sanitary and epidemiological situation in the republic.

Using a national probability sample of adolescents (12–17), this study applies general strain theory to how violent victimization, vicarious violent victimization, and dual violent victimization affect juvenile violent/property crime and drug use. In addition, the mediating effect and moderating effect of depression, low social control, and delinquent peer association on the victimization–delinquency relationship is also examined. Based on SEM analyses and contingency tables, the results indicate that all three types of violent victimization have significant and positive direct effects on violent/property crime and drug use. In addition, the expected mediating effects and moderating effects are also found. Limitations and future directions are discussed.

Full Text Available In discourse about countering terrorism, the term "radicalization" is widely used, but remains poorly defined. To focus narrowly on ideological radicalization risks implying that radical beliefs are a proxy—or at least a necessary precursor—for terrorism, though we know this not to be true. Different pathways and mechanisms of terrorism involvement operate in different ways for different people at different points in time and perhaps in different contexts. This article explores the problems in defining radicalization and radicalism, and suggests that radicalization—and more specifically, involvement in terrorism—might best be viewed as a set of diverse processes. It goes on to review several potentially promising theories that might support further study of those processes, including social movement theory, social psychology, and conversion theory. Finally, it describes some possible frameworks for understanding how the processes might facilitate terrorism-related behavior.

Full Text Available Although most scholars agree that in the last couple of decades, religious fundamentalism has become the dominant ideological feature in the landscape of modern terrorism, many prefer to ignore the fact that this is not a development which is restricted to the Islamic world, and that other religious traditions have also experienced growth in groups which prefer to use violent strategies to promote their sacred visions. The current chapter strives to fill this gap by analyzing the emergence of violent religious groups in two distinct, non-Islamic, religious traditions. At first glance, the Christian Identity and the Religious-Zionist movements have very little in common. However, both movements served as a breeding ground for the emergence of violent fundamentalist groups aspiring to facilitate an apocalyptic/redemption scenario by engaging in illegal violent campaigns. Moreover, in both cases, the role of spiritual leaders was crucial in shaping the radicalization of the groups and their target selection, and the violence had a clear symbolic narrative. In other words, for the members of these violent groups, the violence served a clear role in the mobilization of potential supporters, and the branding and dissemination of the movement's ideology. Finally, while in general, terrorism is perceived as the weapon of the weak, in these two cases it was perpetrated by individuals/groups affiliated to communities belonging to the dominant religious framework in their respective polities (i.e., the Religious-Zionist and Christian Identity movements are perceived by their members as branches of Judaism and Christianity. Hence, by utilizing a comparative framework, the article will not just analyze the violent manifestations that emerged from these two movements, but also try to identify the unique factors that characterize and facilitate the emergence of religious groups within religious communities belonging to the dominant religious tradition in their

Salt marsh losses have been documented worldwide because of land use change, wave erosion, and sea-level rise. It is still unclear how resistant salt marshes are to extreme storms and whether they can survive multiple events without collapsing. Based on a large dataset of salt marsh lateral erosion rates collected around the world, here, we determine the general response of salt marsh boundaries to wave action under normal and extreme weather conditions. As wave energy increases, salt marsh response to wind waves remains linear, and there is not a critical threshold in wave energy above which salt marsh erosion drastically accelerates. We apply our general formulation for salt marsh erosion to historical wave climates at eight salt marsh locations affected by hurricanes in the United States. Based on the analysis of two decades of data, we find that violent storms and hurricanes contribute less than 1% to long-term salt marsh erosion rates. In contrast, moderate storms with a return period of 2.5 mo are those causing the most salt marsh deterioration. Therefore, salt marshes seem more susceptible to variations in mean wave energy rather than changes in the extremes. The intrinsic resistance of salt marshes to violent storms and their predictable erosion rates during moderate events should be taken into account by coastal managers in restoration projects and risk management plans.

We study relaxation patterns of violent conflicts after bursts of activity. Data were obtained from available catalogs on the conflicts in Iraq, Afghanistan and Northern Ireland. We find several examples in each catalog for which the observed relaxation curves can be well described by an asymptotic power-law decay (the analog of the Omori's law in geophysics). The power-law exponents are robust, nearly independent of the conflict. We also discuss the exogenous or endogenous nature of the shocks. Our results suggest that violent conflicts share with earthquakes and other natural and social phenomena a common feature in the dynamics of aftershocks.

Youth reporting combined histories of nonfatal violence, suicidal ideation/behavior, and gun-carrying (VSG) are at risk for perpetrating fatal interpersonal violence and self-harm. We characterized these youth to inform prevention efforts. We analyzed 2004 data from 3,931 seventh-, ninth-, and 11-12th-grade youth and compared VSG youth (n = 66) with non-gun carrying youth who either had no histories of violence or suicidal thoughts/behavior (n = 1,839), histories of violence (n = 884), histories of suicidal thoughts/behaviors (n = 552), or both (n = 590). We compared groups based on demographic factors, risk factors (i.e., friends who engage in delinquency, peer-violence victimization, depressive symptoms, illicit substance use), and protective factors (i.e., school connectedness, parental care and supervision). Regression models identified factors associated with VSG youth. Illicit substance use and having friends who engage in delinquency were more common among VSG youth in all comparisons; almost all VSG youth had high levels of these factors. Depressive symptoms were positively associated with VSG youth versus youth without either violent or suicide-related histories and youth with violent histories alone. School connectedness and parental supervision were negatively associated with VSG youth in most comparisons. Family-focused and school-based interventions that increase connectedness while reducing delinquency and substance use might prevent these violent tendencies.

To determine the most effective pharmacological intervention and to bring recommendations for decision-making in the management of adults with schizophrenia with violent behavior or agitation. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. It is recommended the use of parenteral drugs in all agitated patient who does not respond to the measures of persuasion. The drugs with better evidence on effectiveness (control of violent behavior) are haloperidol and benzodiazepines, administered jointly or individually. Olanzapine is also an option considering that should only be used in institutions where a psychiatrist is available 24hours. Ziprasidone can be considered as a second-line drug. The information about the side effects associated with these drugs is insufficient and has low quality. Violent behavior in adults with schizophrenia represents a risk for themselves and for those around them, so the opportune implementation of interventions aimed to calm the patient, in order to prevent potential negative outcomes is necessary. It is recommended to initiate these interventions with measures of verbal persuasion, and if these measures are not effective, appropriate use of parenteral drugs: haloperidol and benzodiazepines as first-line and olanzapine and ziprasidone as second choices.

It can be theorized that loneliness plays a significant role in the development and continuation of violent, antisocial attitudes and behavior. Analysis of case reports of two serial killers, Dennis Nilsen and Jeffrey Dahmer, indicate that there is evidence for such a link. In this article, a list of significant correlates of loneliness and antisocial behavior is presented. This may be useful for the assessment of possible dangerousness and in the development of prevention and intervention programs. Suggestions are made for the adequate treatment of loneliness and correlated violent, antisocial behavior. A need is recognized for more research into the psychosocial, emotional, neurobiological, cultural, and ethnic determinants of loneliness and their correlation to specific antisocial and/or criminal behavior.
Full Text Available Although selective serotonin reuptake inhibitors (SSRIs are widely prescribed, associations with violence are uncertain.From Swedish national registers we extracted information on 856,493 individuals who were prescribed SSRIs, and subsequent violent crimes during 2006 through 2009. We used stratified Cox regression analyses to compare the rate of violent crime while individuals were prescribed these medications with the rate in the same individuals while not receiving medication. Adjustments were made for other psychotropic medications. Information on all medications was extracted from the Swedish Prescribed Drug Register, with complete national data on all dispensed medications. Information on violent crime convictions was extracted from the Swedish national crime register. Using within-individual models, there was an overall association between SSRIs and violent crime convictions (hazard ratio [HR] = 1.19, 95% CI 1.08-1.32, p < 0.001, absolute risk = 1.0%. With age stratification, there was a significant association between SSRIs and violent crime convictions for individuals aged 15 to 24 y (HR = 1.43, 95% CI 1.19-1.73, p < 0.001, absolute risk = 3.0%. However, there were no significant associations in those aged 25-34 y (HR = 1.20, 95% CI 0.95-1.52, p = 0.125, absolute risk = 1.6%, in those aged 35-44 y (HR = 1.06, 95% CI 0.83-1.35, p = 0.666, absolute risk = 1.2%, or in those aged 45 y or older (HR = 1.07, 95% CI 0.84-1.35, p = 0.594, absolute risk = 0.3%. Associations in those aged 15 to 24 y were also found for violent crime arrests with preliminary investigations (HR = 1.28, 95% CI 1.16-1.41, p < 0.001, non-violent crime convictions (HR = 1.22, 95% CI 1.10-1.34, p < 0.001, non-violent crime arrests (HR = 1.13, 95% CI 1.07-1.20, p < 0.001, non-fatal injuries from accidents (HR = 1.29, 95% CI 1.22-1.36, p < 0.001, and emergency inpatient or outpatient treatment for alcohol intoxication or misuse (HR = 1.98, 95% CI 1.76-2.21, p < 0.001.

What roles do these forms of aggressive behavior play in modern warfare and how are they related to posttraumatic stress symptoms? To answer the question, we sought to determine predictors for appetitive aggressive and trauma-related mental illness, and investigated the frequency of psychopathological symptoms for high- and low-intensity conflict demobilization settings. To this end, we interviewed 213 former members of (paramilitary groups in the eastern Democratic Republic of Congo in regard to their combat exposure, posttraumatic stress, appetitive aggression, depression, suicidality, and drug dependence. Random forest regression embedded in a conditional inference framework revealed that perpetrated violent acts are not necessarily stressful. In fact, the experience of violent acts that typically implicated salient cues of hunting (e.g., blood, suffering of the victim, etc. had the strongest association with an appetite for aggression. Furthermore, the number of lifetime perpetrated violent acts was the most important predictor of appetitive aggression. However, the number of perpetrated violent acts did not significantly affect the posttraumatic stress. Greater intensity of conflict was associated with more severe posttraumatic stress symptoms and depression. Psychotherapeutic interventions that address appetitive aggression in addition to trauma-related mental illness, including drug dependence, therefore seem indispensible for a successful reintegration of those who fought in the current civil wars.

Violent interaction detection is of vital importance in some video surveillance scenarios like railway stations, prisons or psychiatric centres. Existing vision-based methods are mainly based on hand-crafted features such as statistic features between motion regions, leading to a poor adaptability to another dataset. En lightened by the development of convolutional networks on common activity recognition, we construct a FightNet to represent the complicated visual violence interaction. In this paper, a new input modality, image acceleration field is proposed to better extract the motion attributes. Firstly, each video is framed as RGB images. Secondly, optical flow field is computed using the consecutive frames and acceleration field is obtained according to the optical flow field. Thirdly, the FightNet is trained with three kinds of input modalities, i.e., RGB images for spatial networks, optical flow images and acceleration images for temporal networks. By fusing results from different inputs, we conclude whether a video tells a violent event or not. To provide researchers a common ground for comparison, we have collected a violent interaction dataset (VID), containing 2314 videos with 1077 fight ones and 1237 no-fight ones. By comparison with other algorithms, experimental results demonstrate that the proposed model for violent interaction detection shows higher accuracy and better robustness.

This study explores the subject of youth involved in violent groups or gangs, with the goal of further understanding the indoctrination, socialization, and culturalization processes undergone by youth involved in group violence or gangs. Furthermore, to examine the dynamics between peer pressure and other social factors (dating relationships, work, family, etc.) within the theoretical framework of the theories of primary socialization and differential socialization. A qualitative analysis of 40 interviews of youth belonging to violent gangs/groups. According to the theories of primary socialization and differential socialization, over socialization by the violent group and under socialization by all other social entities can be assumed. Regarding parental supervision and support, three family types were clearly associated with the problem of youth violence. The distinct or unified social identity of the violent youth, as well as their individual self esteem and self image, formed a combination of processes whose relevance was highly predictive. Lastly, an accurate indicator of how these youth mature is their support network-perceived, absolute, and relative (distributed among the various influencing forces). The study clearly outlines the need for re-imposing fundamental philosophical epistemology and methodologies on social forces of this kind, incorporating elements key to the postmodern, constructionist, and opposing perspectives.
Longitudinal studies have provided converging evidence linking frequent exposure to violent media in child hood with aggressive later in life. Characteristics of viewers, social environments and media content, were identified as factors that influence the degree to which media violence affects aggression. Research findings ...

This study assessed the speed of recognition of facial emotional expressions (happy and angry) as a function of violent media consumption. Color photos of calm facial expressions morphed to either an angry or a happy facial expression. Participants were asked to make a speeded identification of the emotion (happiness or anger) during the morph.…

Abstract Most studies on the impact of playing violent video games on mental health have focused on aggression. Relatively few studies have examined the relationship between playing violent video games and depression, especially among preadolescent youth. In this study, we investigated whether daily violent video game playing over the past year is associated with a greater number of depressive symptoms among preadolescent youth, after controlling for several well-known correlates of depression among youth. We analyzed cross-sectional data collected from 5,147 fifth-grade students and their primary caregivers who participated in Wave I (2004–2006) of Healthy Passages, a community-based longitudinal study conducted in three U.S. cities. Linear regression was conducted to determine the association between violent video game exposure and number of depressive symptoms, while controlling for gender, race/ethnicity, peer victimization, witnessing violence, being threatened with violence, aggression, family structure, and household income level. We found that students who reported playing high-violence video games for ≥2 hours per day had significantly more depressive symptoms than those who reported playing low-violence video games for video games and number of depressive symptoms among preadolescent youth. More research is needed to examine this association and, if confirmed, to investigate its causality, persistence over time, underlying mechanisms, and clinical implications. PMID:25007237

Nowadays there is a trend towards the use of unimodal databases for multimedia content description, organization and retrieval applications of a single type of content like text, voice and images, instead bimodal databases allow to associate semantically two different types of content like audio-video, image-text, among others. The generation of a bimodal database of audio-video implies the creation of a connection between the multimedia content through the semantic relation that associates the actions of both types of information. This paper describes in detail the used characteristics and methodology for the creation of the bimodal database of violent content; the semantic relationship is stablished by the proposed concepts that describe the audiovisual information. The use of bimodal databases in applications related to the audiovisual content processing allows an increase in the semantic performance only and only if these applications process both type of content. This bimodal database counts with 580 audiovisual annotated segments, with a duration of 28 minutes, divided in 41 classes. Bimodal databases are a tool in the generation of applications for the semantic web.

This study describes and compares the characteristics of patients within a VA Opiate Substitution Therapy Program (OSTP) who report arrests for non-violent and violent crimes and describes patients' attitudes and preferences of criminal treatment within an OSTP. An anonymous survey was distributed to all veterans at one VA-OSTP. Analyses were conducted to describe the sample characteristics and their associations with prior violent and non-violent criminal behavior. A majority of participants were Caucasian, male, middle-aged, unemployed, and had a history of injection drug use. Participants reported arrests for violent (44%), non-violent (47%), and unspecified crimes (16%). There were few significant differences on demographic and drug use characteristics between participants who reported arrests for any violent and only non-violent crimes, and no arrests. Slightly fewer than half the subjects were satisfied with their ability to access treatment for past criminal behavior within or outside of the VA treatment settings. More veterans reporting violent arrests were satisfied with services addressing criminal behavior within the VA-OSTP than were veterans reporting only nonviolent arrests. Nearly equal proportions of veterans reporting violent (45%) and non-violent (44%) arrests reported dissatisfaction with such services received outside of the VA-OSTP. Prior violent criminal behavior is common among participants of a VA-OSTP. Many individuals with criminal histories seek treatment for criminality within VA-OSTP.

Using a sample of 703 African American adolescents from the Family and Community Health Study (FACHS) along with census data from the year 2000, we examine the association between neighborhood-level gender equality and violence. We find that boys' and girls' violent behavior is unevenly distributed across neighborhood contexts. In particular, gender differences in violent behavior are less pronounced in gender-equalitarian neighborhoods compared to those characterized by gender inequality. We also find that the gender gap narrows in gender-equalitarian neighborhoods because boys' rates of violence decrease whereas girls' rates remain relatively low across neighborhoods. This is in stark contrast to the pessimistic predictions of theorists who argue that the narrowing of the gender gap in equalitarian settings is the result of an increase in girls' violence. In addition, the relationship between neighborhood gender equality and violence is mediated by a specific articulation of masculinity characterized by toughness. Our results provide evidence for the use of gender-specific neighborhood prevention programs.

Traditional red terrorist organizations (combatant communist parties like the RAF, the RB etc. have been replaced by small militant groups, by violent militancy campaigns, by anti-globalist violence or by “single-issue” terrorism. The militant extreme left may itself be both a direct and indirect ally to other forms of terrorism, including Islamist terrorism.
Full Text Available Abstract Background The validity of traditional categorical personality disorder diagnoses is currently re-evaluated from a continuous perspective, and the evolving DSM-V classification may describe personality disorders dimensionally. The utility of dimensional personality assessment, however, is unclear in violent offenders with severe personality pathology. Methods The temperament structure of 114 alcoholic violent offenders with antisocial personality disorder (ASPD was compared to 84 offenders without ASPD, and 170 healthy controls. Inclusion occurred during a court-ordered mental examination preceded by homicide, assault, battery, rape or arson. Participants underwent assessment of temperament with the Tridimensional Personality Questionnaire (TPQ and were diagnosed with DSM-III-R criteria. Results The typical temperament profile in violent offender having ASPD comprised high novelty seeking, high harm avoidance, and low reward dependence. A 21% minority scored low in trait harm avoidance. Results, including the polarized harm avoidance dimension, are in accordance with Cloninger's hypothesis of dimensional description of ASPD. The low harm avoidance offenders committed less impulsive violence than high harm avoidance offenders. High harm avoidance was associated with comorbid antisocial personality disorder and borderline personality disorder. Conclusion Results indicate that the DSM based ASPD diagnosis in alcoholic violent offenders associates with impulsiveness and high novelty seeking but comprises two different types of ASPD associated with distinct second-order traits that possibly explain differences in type of violent criminality. Low harm avoidance offenders have many traits in common with high scorers on the Hare Psychopathy Checklist-Revised (PCL-R. Results link high harm avoidance with broad personality pathology and argue for the usefulness of self-report questionnaires in clinical praxis.

Research into the causal and perpetuating factors influencing aggression has partly focused on the general tendency of aggression-prone individuals to infer hostile intent in others, even in ambiguous circumstances. This is referred to as the ‘hostile interpretation bias’. Whether this hostile interpretation bias also exists in basal information processing, such as perception of facial emotion, is not yet known, especially with respect to the perception of ambiguous expressions. In addition, little is known about how this potential bias in facial emotion perception is related to specific characteristics of aggression. In the present study, conducted in a penitentiary setting with detained male adults, we investigated if violent offenders (n = 71) show a stronger tendency to interpret ambiguous facial expressions on a computer task as angry rather than happy, compared to non-violent offenders (n = 14) and to a control group of healthy volunteers (n = 32). We also investigated if hostile perception of facial expressions is related to specific characteristics of aggression, such as proactive and reactive aggression. No clear statistical evidence was found that violent offenders perceived facial emotional expressions as more angry than non-violent offenders or healthy volunteers. A regression analysis in the violent offender group showed that only age and a self-report measure of hostility predicted outcome on the emotion perception task. Other traits, such as psychopathic traits, intelligence, attention and a tendency to jump to conclusions were not associated with interpretation of anger in facial emotional expressions. We discuss the possible impact of the study design and population studied on our results, as well as implications for future studies. PMID:29190802

Evaluation of the efficacy of a short-course, personalized self-management and intensive spa therapy intervention as active prevention of musculoskeletal disorders of the upper extremities (Muska): a research protocol for a randomized controlled trial.

Musculoskeletal disorders (MSDs) constitute a major occupational health problem in the working population, substantially impacting the quality of life of employees. They also cause considerable economic cost to the healthcare system, with, notably, the reimbursement of treatments and compensation for lost income. MSDs manifest as localized pain or functional difficulty in one or more anatomical areas, such as the cervical spine, shoulder, elbow, hand, and wrist. Although prevalence varies depending on the region considered and the method of assessment, a prevalence of 30% is found in different epidemiological studies. The disease needs to be prevented, not only for medical and economic reasons, but also for legal reasons, owing to the requirement of assessing occupational risks. The strategy envisaged may thus revolve around active, multimodal prevention that has employees fully involved at the heart of their care. Although physical exercise is widely recommended, few studies with a good level of evidence have enabled us to base a complete, well-constructed intervention on exercise that can be offered as secondary prevention in these disorders. A prospective, multicenter, comparative (intervention arm vs. control arm), randomized (immediate vs. later treatment) study using Zelen's design. This study falls under active prevention of MSDs of the upper extremities (UE-MSDs). Participants are workers aged between 18 and 65 years with latent or symptomatic MSDS, with any type of job or workstation, with or without an history of sick leave. The primary aim is to show the superiority at 3 months of a combination of spa therapy, exercise, and self-management workshops for 6 days over usual care in the management of MSDs in terms of employee functional capacity in personal and professional daily life. Secondary aims are to assess the benefit of the intervention in terms of pain, quality of life, and accumulated duration of sick leave. This randomized controlled trial is

Objectives Although it is well known that people with alcohol dependence are at a markedly elevated risk for suicide, much less is known about the role of acute alcohol use in suicidal behaviours. The primary aims of this epidemiological study were to assess the prevalence and factors associated with acute alcohol intoxication among 57 813 suicide decedents in 16 states. Methods Data from the restricted National Violent Death Reporting System 2003–2009 for male and female suicide decedents aged 18 years and older were analysed by multiple logistic regression to compare decedents with and without acute alcohol intoxication (defined as blood alcohol concentration (BAC) ≥0.08 g/dl). Results Among men, those who were younger, American Indian/Alaska Native, Hispanic, veterans, of lower educational attainment, deceased from a self-inflicted firearm injury or hanging/suffocation and residing in rural areas were more likely to have been intoxicated at the time of death. Among women, the factors associated with a BAC ≥0.08 g/dl were younger age, being American Indian/Alaska Native, and using a firearm, hanging/suffocation or falling as method of death. Conclusions In both men and women, alcohol intoxication was associated with violent methods of suicide and declined markedly with age, suggesting that addressing risks associated with acute alcohol use may be of the greatest aid in the prevention of violent suicides among young and middle age adults.

We examined the relationship of exposure to domestic violence and violence occurring outside home to bullying behaviour in a sample (508; 40.9% males, 59.1% females) of underage psychiatric inpatient adolescents. Participants were interviewed using K-SADS-PL to assess DSM-IV psychiatric diagnoses and to gather information about domestic and other violence and bullying behaviour. Witnessing interparental violence increased the risk of being a victim of bullying up to 2.5-fold among boys. For girls, being a victim of a violent crime was an over 10-fold risk factor for being a bully-victim. Gender differences were seen in witnessing of a violent crime; girls were more likely to be bullies than boys. Further, as regards being a victim of a violent crime outside home and physical abuse by parents at home, girls were significantly more often bully-victims than boys. When interfering and preventing bullying behaviour, it is important to screen adolescents' earlier experiences of violence.

Although many suicide prevention programs focus on youth suicides, data indicate the vast majority of suicides occur among adults (18-64 years). In 2005 New Mexico joined the Centers for Disease Control and Prevention's National Violent Death Reporting System, collecting data on suicides, homicides, and unintentional firearm fatalities to better inform state and national prevention programs. We utilized data collected by the New Mexico Violent Death Reporting System in its first 2 years of operation (2005 and 2006) in order to define the demographic patterns of adult suicides in the state and characterize risk factors. A total of 526 suicides occurred among adults during this time, with the majority being male (78.5%) and White non-Hispanic (56.7%). The highest incidence was in adults between 45 and 54 years (28.1%). Firearms were the most commonly used mechanism, and "current depressed mood" the most commonly identified risk factor. High rates of adult suicide indicate the need for targeted prevention programs.

Growing concerns exist about violent crimes perpetrated by U.S. military personnel. Although interventions exist to reduce violent crimes in high-risk populations, optimal implementation requires evidence-based targeting. The goal of the current study was to use machine learning methods (stepwise and penalized regression; random forests) to develop models to predict minor violent crime perpetration among U.S. Army soldiers. Predictors were abstracted from administrative data available for all 975,057 soldiers in the U.S. Army 2004-2009, among whom 25,966 men and 2728 women committed a first founded minor violent crime (simple assault, blackmail-extortion-intimidation, rioting, harassment). Temporally prior administrative records measuring socio-demographic, Army career, criminal justice, medical/pharmacy, and contextual variables were used to build separate male and female prediction models that were then tested in an independent 2011-2013 sample. Final model predictors included young age, low education, early career stage, prior crime involvement, and outpatient treatment for diverse emotional and substance use problems. Area under the receiver operating characteristic curve was 0.79 (for men and women) in the 2004-2009 training sample and 0.74-0.82 (men-women) in the 2011-2013 test sample. 30.5-28.9% (men-women) of all administratively-recorded crimes in 2004-2009 were committed by the 5% of soldiers having highest predicted risk, with similar proportions (28.5-29.0%) when the 2004-2009 coefficients were applied to the 2011-2013 test sample. These results suggest that it may be possible to target soldiers at high-risk of violence perpetration for preventive interventions, although final decisions about such interventions would require weighing predicted effectiveness against intervention costs and competing risks.

Violence against women has been extensively studied in various disciplines, whereas less attention has been paid to the experiences of men. Even the violent behavior of men in their intimate relationships has been mostly studied as experienced by women. This study follows Husserlian descriptive phenomenology. Twenty open-ended interviews were conducted with 10 Finnish men with a history of intimate partner violence (IPV). The data were analyzed by the method developed by Colaizzi. Findings suggested that men considered communication and dynamics of the relationship important. Fundamentally, these abusive men had a need to be respected as men, and they sought to experience human dignity. It is necessary to readjust the framework on interpersonal violence, listen to the voice of men, and develop prevention, early identification, and supportive intervention strategies for men, couples, and families. Research on IPV should be expanded to include the experiences of both genders.

The case of Anders Breivik, who committed mass murder in Norway in 2011, stirred controversy among forensic mental health experts. His bizarrely composed compendium and references to himself as the "Knights Templar" raised concerns that he had a psychotic mental illness. Beliefs such as Mr. Breivik's that precede odd, unusual, or extremely violent behavior present a unique challenge to the forensic evaluator, who sometimes struggles to understand those beliefs. Psychotic disorder frequently is invoked to characterize odd, unusual, or extreme beliefs, with a classification that has evolved over time. However, the important concept of overvalued idea, largely ignored in American psychiatry, may better characterize these beliefs in some cases. We discuss the definitions of delusion and overvalued ideas in the context of Anders Breivik's rigidly held extreme beliefs. We also review the British definition of overvalued idea and discuss McHugh's construct, to introduce the term "extreme overvalued belief" as an aid in sharpening the forensic evaluator's conceptualization of these and similar beliefs. © 2016 American Academy of Psychiatry and the Law.

An H-function is any function of the phase space distribution function F(x,v) which is non-decreasing with time. In collisionless systems Boltzmann's H-function - integral F log F dx dv is only one of a variety of H-functions of the form - integral C(F) dx dv, where C is any convex function. Every equilibrium stellar system in which the distribution function is a decreasing function of the energy alone is a stationary point of some H-function of this form. During violent relaxation, all such H-functions must increase, and the distribution function is said to become 'more mixed'. A simple criterion is given for determining whether a given distribution function is more mixed than another; this criterion is used to show that a violently relaxed galaxy resembles observed elliptical galaxies only if the initial state is cold or clumpy.

Purpose. The present study of forensic hospital patients examined whether their imagination of violence is related to self-reported anger, psychological distress, and to staff observations of aggressive behaviour in hospital. In view of the relevance of psychological trauma for anger and aggression......, we further investigate whether the associations of imagined violence to anger and aggression are stronger when the patient has trauma-related intrusion symptoms. Methods. Participating male forensic inpatients (N = 54) were individually tested and followed-up for five months. Aggressive episodes were...... the follow-up period. Imagined violence and trauma-related intrusions separately contributed to anger and aggressive behaviour. Conclusions. The study calls attention to violent images as an important variable involved in aggressive responding. The role of violent images as a mediator of the well...

Desensitization to violence is cited frequently as being an outcome of exposure to media violence and a condition that contributes to increased aggression. This article initiates the development of a conceptual model for describing possible relationships among violent video games, brain function, and desensitization by using empathy and attitudes toward violence as proxy measures of desensitization. More work is needed to understand how specific game content may affect brain activity, how brain development may be affected by heavy play at young ages, and how personality and lifestyle variables may moderate game influence. Given the current state of knowledge, recommendations are made for clinicians to help parents monitor and limit exposure to violent video games and encourage critical thinking about media violence.

This paper scrutinizes the impact of intolerance toward diverse ethnic, religious, and cultural groups on an individual's willingness to actively engage in non-violent protest. Following new insights, we examine the individual as well as the ecological effect of social intolerance on protest...... behavior. Drawing from insights of social psychology and communication science, we expect that the prevalence of intolerance reinforces the positive effect of individual-level intolerance on protest participation. From a rational choice perspective, however, a negative moderating effect is expected......, as the expression of opinions becomes redundant for intolerant individuals in an intolerant society. We base our multilevel analyses on data from the World Values Surveys covering 32 established democracies. Our results reveal that intolerance leads to more non-violent protest participation. This relationship...

This study describes epidemiologic patterns of mortality due to suicide, homicide, and war for the world in order to serve as a benchmark against which to measure future progress and to raise awareness about violence as a global public health problem. The world and its eight major regions. Data were derived from The Global Burden of Disease series and the US National Center for Health Statistics to estimate crude rates, age adjusted rates, sex rate ratios, and the health burden for suicide, homicide, and war related deaths for the world and its eight major regions in 1990. In 1990, an estimated 1,851,000 people died from violence (35.3 per 100,000) in the world. There were an estimated 786,000 suicides. Overall suicide rates ranged from 3.4 per 100,000 in Sub-Saharan Africa to 30.4 per 100,000 in China. There were an estimated 563,000 homicides. Overall homicide rates ranged from 1.0 per 100,000 in established market economies to 44.8 per 100,000 in Sub-Saharan Africa with peaks among males aged 15-24 years old, and among females aged 0-4 years old. There were an estimated 502,000 war related deaths with peaks in rates for both sexes among people aged 0-4, 15-29, and 60-69 years old. The number of violence related deaths in the world is unacceptably high. Coordinated prevention and control efforts are urgently needed.

There is no literature investigating denial of aggression in schizophrenia. Our goal was to study this phenomenon and to determine what deficits are associated with it. 102 inpatients with schizophrenia were divided into three groups: (1) patients with a documented history of violent crime who denied it on extensive interviews ("deniers"); (2) those with such a history who admitted to it; and (3) those without violent crime. Patients were administered a psychometrically validated self-report scale of aggression, the Buss-Perry Aggression Questionnaire (BPAQ), the Positive and Negative Syndrome Scale and a comprehensive neurocognitive battery. They were followed for twelve weeks during which all violent incidents were recorded. The deniers were significantly more impaired in executive function, but not in any other cognitive domain. They did not evidence more severe psychotic symptoms or greater lack of insight in their psychosis, but this lack of insight was strongly related to hostility and suspiciousness. Their denial of aggression was also evidenced in a significantly lower self-reported BPAQ aggression score. In the patients who admitted to violent crimes, baseline BPAQ aggression score predicted subsequent aggression; in the deniers, it was negatively related to subsequent aggression. Denial of aggression is associated with executive dysfunction which facilitates a misappraisal of the surrounding world as threatening and hostile. For those who admit to crimes, self-reported aggression predicts future aggression. In contrast, in the deniers, the extent of denial is related to future aggression. The denial itself is a marker of greater aggressive tendencies. Copyright © 2012. Published by Elsevier B.V.

Many adolescents are exposed to violence in their schools, communities and homes. Exposure to violence at high levels or across multiple contexts has been linked with emotional desensitization, indicated by low levels of internalizing symptoms. However, the long-term consequences of such desensitization are unknown. This study examined emotional desensitization to violence, together with externalizing problems, as mediators of the relationship between exposure to violence in pre-adolescence and violent behavior in late adolescence. A community sample of youth (N = 704; 48% female; 76% African American, 22% Caucasian) reported on their exposure to violence in multiple settings at ages 11, 13 and 18. Internalizing and externalizing problems were assessed at ages 11 and 13; violent behavior was measured at age 18. Structural Equation Modeling showed that exposure to high levels of violence at age 11 was associated with lower levels of internalizing problems (quadratic effect) at age 13, as was exposure to violence across multiple contexts (linear effect). In turn, fewer internalizing problems and more externalizing problems at age 13 predicted more violent behavior at age 18. The results suggest that emotional desensitization to violence in early adolescence contributes to serious violence in late adolescence.

Many adolescents are exposed to violence in their schools, communities and homes. Exposure to violence at high levels or across multiple contexts has been linked with emotional desensitization, indicated by low levels of internalizing symptoms. However, the long-term consequences of such desensitization are unknown. This study examined emotional desensitization to violence, together with externalizing problems, as mediators of the relationship between exposure to violence in pre-adolescence and violent behavior in late adolescence. A community sample of youth (N=704; 48% female; 76% African American, 22% Caucasian) reported on their exposure to violence in multiple settings at ages 11, 13 and 18. Internalizing and externalizing problems were assessed at ages 11 and 13; violent behavior was measured at age 18. Structural Equation Modeling showed that exposure to high levels of violence at age 11 was associated with lower levels of internalizing problems (quadratic effect) at age 13, as was exposure to violence across multiple contexts (linear effect). In turn, fewer internalizing problems and more externalizing problems at age 13 predicted more violent behavior at age 18. The results suggest that emotional desensitization to violence in early adolescence contributes to serious violence in late adolescence. PMID:25684447

We explored the causes and circumstances of violent behaviour among a group of child labourers in the Indian unorganized sectors. From 14 categories of occupations, a total of 1,400 child labourers were interviewed in both urban and rural areas. The average family size of these mostly illiterate child labourers is seven, and average family income is 3,200 INR per month. In the short term child labourers become violent, aggressive, and criminal, following a pyramid of violent behaviour, including socio-economic pressure, cultural deviance, and psychological pressure. When considering family history it seems that the problem is part of a vicious cycle of violence, which persists through generations and evolves with financial crisis, early marriage, and violence in the family and workplace. Our study demonstrates that the most vulnerable groups of child labourers belong to the following workplaces: dhabas, food stalls, rail/bus stations, rail-floor cleaning, and rag picking. Giving high priority to capacity building within the community, including support for locally-generated solutions, is warranted.

There is great concern about the effects of playing violent video games on aggressive behavior. The present experimental study was aimed at investigating the differential effects of actively playing vs. passively watching the same violent video game on subsequent aggressive behavior. Fifty-seven children aged 10-13 either played a violent video game (active violent condition), watched the same violent video game (passive violent condition), or played a non-violent video game (active non-violent condition). Aggression was measured through peer nominations of real-life aggressive incidents during a free play session at school. After the active participation of actually playing the violent video game, boys behaved more aggressively than did the boys in the passive game condition. For girls, game condition was not related to aggression. These findings indicate that, specifically for boys, playing a violent video game should lead to more aggression than watching television violence. Copyright 2007 Wiley-Liss, Inc.

The effects of witnessing and experiencing crime have seldom been disaggregated. Little research has assessed the effect of multiple exposures to crime. We assess independent contributions of self-reported crime and area-level crime to adolescent behavioral health outcomes. Cross sectional data on 5519 adolescents from the Comprehensive Community Mental Health Services for Children and their Families Program was linked to FBI crime rate data to assess associations of mutually exclusive categories of self-reported crime exposure and area-level crime rates with mental health and substance abuse. Self-reported crime exposure was significantly associated with poorer behavioral health. Violent victimization had the largest association with all outcomes except internalizing scores. All self-reported crime variables were significantly associated with three of the outcomes. Area-level crime rates were associated with one mental health outcome. Providers should assess direct and indirect crime exposure rather than only focusing on violent victimization.
Full Text Available During the sixty-year period of its existence, Grand-Guignol, the French theatre of horror, gained a status of a legendary theatre which dealt with horrors and terrors of human mind, successfully connecting faits divers (common, everyday facts with the erotic and titillating scenes of violence on stage. The performance style, the writing, the special effects, and the directorship over the course of years, made this theatre a legendary place where blood flowed in streams and people fainted during performances, in this way making its indelible mark in horror genre today. In this paper, the author is trying to focus the attention on the theatre of Grand-Guignol as a form of violent entertainment and the way the representations of violence and horror enacted on its stage affected the audience, through Goldstein’s theory of the importance of visual imagery in different media today. Furthermore, through comparison of violent acts presented on the stage of the Grand-Guignol and the atmosphere they create in the viewer’s mind with some of the aspects of Artaud’s vision of his theatre of cruelty, the author attempts to show how this form of violent entertainment in the theatrical media influences the vision of that same violence within the audience, with the sense of security as the main idea in which the viewers feel safe to enjoy, envision and in a way become the participants in the performances enacted on the small stage of the Grand-Guignol.

Significant, and usually unwelcome, surprises, such as floods, financial crisis, epileptic seizures, or material rupture, are the topics of Extreme Events in Nature and Society. The book, authored by foremost experts in these fields, reveals unifying and distinguishing features of extreme events, including problems of understanding and modelling their origin, spatial and temporal extension, and potential impact. The chapters converge towards the difficult problem of anticipation: forecasting the event and proposing measures to moderate or prevent it. Extreme Events in Nature and Society will interest not only specialists, but also the general reader eager to learn how the multifaceted field of extreme events can be viewed as a coherent whole.

In this study, and with a view to extending upon existing findings on the effects of general violent media on violent cognitions, we experimentally measured the relationship between exposure to extremist propaganda and violent cognitions. Our results countered our hypotheses and the wider findings of violent media and aggression that exposure to violent stimuli increases violent thoughts and that this effect is moderated by trait aggression. Specifically, this study found that participants with low and medium trait aggression became more pro-social after being exposed to extremist propaganda. We discuss these results with reference to theories of terror management and mortality salience, as well as the implications of these results for wider theories of the role of online extremist material in the wider "radicalization" process.

This research was designed to explore the relationship between violent video game play and attitudes towards victims. As the violent genre of games become more popular and as the graphics and content becomes even more realistic and immersive, there has been concern that this media form offers a different perspective on violence to players than more passive forms of media. Much of the research in the area of violent video game research has focused on changes in players in terms of aggressive b...

To evaluate the impact that a violent and a non-violent movie may cause on scholars. In Bogotá, 125 public primary school students were surveyed, applying a questionnaire to learn both about their daily life violence and their attitude towards it. Two weeks later, they were shown one violent movie, and two weeks later a non-violent one. Children were asked to draw their families, express their opinions and answer a questionnaire after each movie. The initial survey showed that 23.6% of the children reported violent responses when they were offended, 39.8% reported some kind of familiar violence and 19.5% identified themselves with a violent figure. Boys were more prone to respond violently when offended and to identify themselves with a violent figure than girls (p=0.004). Compared with the non-violent movie, a greater percentage of children excluded themselves from the family drawing after watching the violent movie (Odds Ratio (OR): 2.55; 95% Interval Confidence (95% CI) 1.22-5.43, p=0.01). The family drawing after the violent movie also showed more emotional signs (OR: 3.13; 95% CI: 1.35-7.52; p=0.0053) and more aggressive signs (OR: 2.55; 95% CI: 1.22-5.43; p=0.01) than the family drawing after the non-violent movie. The family drawing test showed the immediate impact of television. Television violence negatively influences kids and should be avoided.

Disappearances are a frequent phenomenon in the context of violent conflicts. Although it is widely assumed that relatives of missing people face particularly complex adaptation difficulties due to the uncertainty regarding the fate of their loved ones, little is known about the psychological and social consequences for those left behind. The aim of this article is to provide an empirical overview on studies addressing ambiguous loss in violent conflicts as well as to highlight potential risk factors for negative mental health outcomes relevant in this group. Due to the limited number of studies, only preliminary conclusions can be drawn. Studies show that the disappearance of a loved one can adversely affect mental health in a substantial number of those left behind. Studies indicate that relatives of missing persons suffer from higher psychological distress than bereaved persons with confirmed losses, particularly in terms of symptom severity of depression and prolonged grief reactions. Research on factors contributing to these mental health outcomes suggests an elevated risk for exposure to traumatic events and lack of social support among relatives of missing persons. The extent of hope regarding the fate of the missing loved one might prevent relatives from achieving closure and facilitate prolonged grief reactions. Lack of grief rituals and complex family dynamics may furthermore exacerbate coping with the loss. Future research should focus on the verification of these findings and evaluate the impact of resilience factors that can protect relatives from maladaptive mental health consequences. Research in this regard can help identify persons at high risk and allow the development of adequate and effective interventions.
The 20th century was a century of genocide and other great violence between groups within societies. Already at the beginning of the 21st century, there have been mass killings, civil wars, violent conflict, and terrorism. This article summarizes influences that tend to lead to intense group violence. It then considers prevention, stressing early prevention--and reconciliation as an aspect of prevention--and focusing on central principles and practices. The principles include developing positive orientations to previously devalued groups; healing from past victimization and promoting altruism born of suffering; moderating respect for authority; creating constructive ideologies; promoting understanding of the origins of violence, its impact, and avenues to prevention; promoting truth, justice, and a shared history; and raising inclusively caring, morally courageous children. Practices related to all of these are also discussed. The article stresses the role of progressive change, that is, of psychological, behavioral, and social evolution, in both extreme violence and positive relations between groups; the role of passive bystanders in the unfolding of violence; and the role of active bystandership in the prevention of violence, in the promotion of reconciliation, and in the development of harmonious societies. It emphasizes psychological processes but notes the importance of creating societal institutions. The author cites findings from both laboratory research and case studies, reviews interventions and their evaluation in Rwanda, and points to the need for further research.

Although sex-role identification has been found to be associated with crime and delinquency, the link between sex-role identification and violent victimization has remained largely unexplored. Using the Add Health data, this study examines sex-role identification and its relationship to violent victimization. The findings suggest that masculinity increases the risk of violent victimization for males, but does not for females. Other differences in risk factors across gender were also found. These findings indicate that masculinity is an important construct in understanding the complexity of why some persons are violently victimized and others are not.

The goal was to examine the association between violence in the media and the expression of seriously violent behavior among older children and teenagers in a national sample. The Growing up with Media survey was a national, online survey of 1588 youths that was conducted in August and September 2006. Participants were 10- to 15-year-old youths who had used the Internet at least once in the past 6 months. The main outcome measure was self-reported seriously violent behavior, including (1) shooting or stabbing someone, (2) aggravated assault, (3) robbery, and (4) sexual assault. Five percent of youths reported engaging in seriously violent behavior in the past 12 months. Thirty-eight percent reported exposure to violence online. Exposures to violence in the media, both online and off-line, were associated with significantly elevated odds for concurrently reporting seriously violent behavior. Compared with otherwise similar youths, those who indicated that many, most, or all of the Web sites they visited depicted real people engaged in violent behavior were significantly more likely to report seriously violent behavior. After adjustment for underlying differences in youth characteristics, respondents' alcohol use, propensity to respond to stimuli with anger, delinquent peers, parental monitoring, and exposures to violence in the community also were associated with significantly increased odds of concurrently reporting seriously violent behavior. Exposure to violence in the media is associated with concurrent reports of seriously violent behavior across media (eg, games and music). Newer forms of violent media seem to be especially concerning.

This study used a within-participant design to evaluate the concurrent validity and test-retest reliability of the Violent Ideations Scale in a general population, English-speaking opportunistic sample. Data from 116 adult participants ( M age = 33.7, SD = 11.9, male = 30 [25.9%]) were used to compare scores on the Violent Ideations Scale and Aggression Questionnaire and responses to the Schedule of Imagined Violence. A subgroup of 27 participants ( M age = 37.2, SD = 13.6, male = 8 [29.6%]) completed the Violent Ideations Scale on a second occasion, 2 weeks later. The Violent Ideations Scale was found to correlate significantly with the Aggression Questionnaire subscale and total scores, with the strongest correlations being with physical aggression and total scores. Participants were more likely to be categorized as having experienced a violent ideation based on responses to the Violent Ideation Scale, compared with the Schedule of Imagined Violence, most likely due to the Schedule of Imagined Violence underestimating the prevalence of violent ideation. A significant, strong correlation was found between total Violent Ideations Scale scores at Time 1 and Time 2. Overall, the Violent Ideations Scale was found to have concurrent validity when compared with the Aggression Questionnaire and good test-retest reliability, suggesting that it would be suitable for use with a nonclinical, English-speaking sample.

The objective of this study was to test the effect of individual differences on appeal and use of video games. Participants were 299 adolescent boys from lower and higher secondary schools in the Netherlands and Belgium. In general, boys were most attracted to violent video games. Boys that scored higher in trait aggressiveness and lower in empathy were especially attracted to violent games and spent more time playing video games than did boys lower in trait aggressiveness. Lower educated boys showed more appreciation for both violent and nonviolent games and spent more time playing them than did higher educated boys. The present study showed that aggressive and less empathic boys were most attracted to violent games. The fact that heavy users of violent games show less empathy and higher aggressiveness suggests the possibility of desensitization. Other studies have shown that playing violent games increases aggressiveness and decreases empathy. These results combined suggest the possibility of a violence cycle. Aggressive individuals are attracted to violent games. Playing violent games increases aggressiveness and decreases empathy, which in turn leads to increased appreciation and use of violent games.

Playing violent video games have been linked to long-term emotional desensitization. We hypothesized that desensitization effects in excessive users of violent video games should lead to decreased brain activations to highly salient emotional pictures in emotional sensitivity brain regions. Twenty-eight male adult subjects showing excessive long-term use of violent video games and age and education matched control participants were examined in two experiments using standardized emotional pictures of positive, negative and neutral valence. No group differences were revealed even at reduced statistical thresholds which speaks against desensitization of emotion sensitive brain regions as a result of excessive use of violent video games.

Cities are fast becoming new territories of violence. The humanitarian consequences of many criminally violent urban settings are comparable to those of more traditional wars, yet despite the intensity of the needs, humanitarian aid to such settings is limited. The way in which humanitarian needs are typically defined, fails to address the problems of these contexts, the suffering they produce and the populations affected. Distinctions between formal armed conflicts, regulated by international humanitarian law, and other violent settings, as well as those between emergency and developmental assistance, can lead to the neglect of populations in distress. It can take a lot of time and effort to access vulnerable communities and implement programmes in urban settings, but experience shows that it is possible to provide humanitarian assistance with a significant focus on the direct and indirect health consequences of violence outside a traditional conflict setting.

Impairments in executive functioning give rise to reduced control of behavior and impulses, and are therefore a risk factor for violence and criminal behavior. However, the contribution of specific underlying processes remains unclear. A crucial element of executive functioning, and essential for cognitive control and goal-directed behavior, is visual attention. To further elucidate the importance of attentional functioning in the general offender population, we employed an attentional capture task to measure visual attention. We expected offenders to have impaired visual attention, as revealed by increased attentional capture, compared to healthy controls. When comparing the performance of 62 offenders to 69 healthy community controls, we found our hypothesis to be partly confirmed. Offenders were more accurate overall, more accurate in the absence of distracting information, suggesting superior attention. In the presence of distracting information offenders were significantly less accurate compared to when no distracting information was present. Together, these findings indicate that violent offenders may have superior attention, yet worse control over attention. As such, violent offenders may have trouble adjusting to unexpected, irrelevant stimuli, which may relate to failures in self-regulation and inhibitory control. Copyright © 2017 The Authors.

Several studies have reported criminal and violent behaviour in people with schizophrenia but few have investigated the association between affective disorders and violent behaviour. We reviewed the national crime register for records of criminal offences committed by 1561 patients with affective disorders treated between 1990 and 1995 in the Psychiatric Hospital of the University of Munich. The sample was divided into patients with bipolar I disorder, manic disorder and major depressive disorder. Sociodemographic and other risk factors for non-violent and violent criminal behaviour were analysed. Sixty-five (4.16%) patients had been convicted in the 7 to 12 years after discharge (307 cases). The rate of criminal behaviour and violent crimes was highest in the manic disorder group: 15.7% (14 of 89) were listed in the national crime register and 5.6% (5 of 89) were convicted of physical injury offences. Violence and criminality were comparatively rare in patients with major depressive disorder: only 1.42% (10 of 702) committed violent crimes. Male gender was a substantial risk factor for non-violent and especially violent behaviour: the rate of violent crimes was six times higher than in females. Marital status appeared to influence the prevalence of later delinquency: separated, divorced and widowed patients committed offences more frequently. A history of substance use problems before clinical treatment was reported by 21.2% (329 of 1561) of the sample. A wide range of different crimes were committed, with defalcation, theft and fraud being the most frequent. Twenty-one cases of physical assault and one case of later homicide were recorded. In contrast to other forensic studies, we did not find a significant effect of substance abuse on the risk of later delinquent behaviour. The frequency of criminal behaviour and violent crimes in individuals with affective disorder depends on much more than just the diagnosis. This study may stimulate further research to
Full Text Available This article considers the ways in which knowledge and research influenced the design of a programme to reduce violent conflict in Nigeria. The diversity of sources and forms of conflict in Nigeria, and the way that local grievances interact with national struggles over politics and resources, combined with a need to show measurable results within five years, made the task of programme design extremely challenging. The article discusses how the project design team responded to this challenge. It describes the four main lessons that emerged from dialogue-based research studies that helped the design team formulate a theory of change for the programme, and subsequently its methodological approach and activities. The studies shaped the central theme of the project, which was the need to transform conflict management institutions into genuinely inclusive forums for dialogue, thereby regaining the trust of those currently excluded from dialogue but yet most affected by violence – particularly unemployed youth and women and girls. The article does not portray research and knowledge simplistically, as the sole solution to project design issues. Rather, it shows that if research findings can take designers directly to the core of the problems as perceived by those most affected by them, then they can play a critical role in designing appropriate interventions and, as implementation proceeds, to demonstrating progress towards project goals.

Classrooms in Peace (Aulas en Paz) is an elementary school-based multicomponent program for prevention of aggression and promotion of peaceful relationships. Inspired by international programs and socio-emotional research, it includes (1) a classroom universal curriculum, (2) parent workshops and home visits to parents of the 10% most aggressive children, and (3) extracurricular peer groups of two aggressive and four prosocial children. Activities seek to promote socio-emotional competencies such as empathy, anger management, creative generation of alternatives, and assertiveness. A 2-year quasi-experimental evaluation was conducted with 1154 students from 55 classrooms of seven public schools located in neighborhoods with the presence of youth gangs, drug cartels, and high levels of community violence in two Colombian cities. Despite several implementation (e.g., about half of the activities were not implemented) and evaluation (e.g., randomization problems, large number of missing data, and changes between treatment and control groups) challenges, positive results were found in prosocial behavior and in reduction of aggressive behavior, according to teacher reports, and in assertiveness and reduction of verbal victimization, according to student reports. Furthermore, implementation cost (25 US dollars per student per year) was very low compared to other programs in developed countries. This study shows that the Classrooms in Peace program has an important potential to generate positive results and highlights the challenges of implementing and evaluating prevention programs in highly violent environments.

The cumulative exposure to life-threatening events increases the risk for posttraumatic stress disorder (PTSD). However, over the course of evolutionary adaptation, intra-species killing may have also evolved as an inborn strategy leading to greater reproductive success. Assuming that homicide has evolved as a profitable strategy in humans, a protective mechanism must prevent the perpetrator from getting traumatised by self-initiated violent acts. We thus postulate an inverse relation between a person's propensity toward violence and PTSD. We surveyed a sample of 269 Rwandan prisoners who were accused or convicted for crimes related to the 1994 genocide. In structured interviews we assessed traumatic event types, types of crimes committed, the person's appetitive violence experience with the Appetitive Aggression Scale (AAS) and PTSD symptom severity with the PSS-I. Using path-analysis, we found a dose-response effect between the exposure to traumatic events and the PTSD symptom severity (PSS-I). Moreover, participants who had reported that they committed more types of crimes demonstrated a higher AAS score. In turn, higher AAS scores predicted lower PTSD symptom severity scores. This study provides first empirical support that the victim's struggling can be an essential rewarding cue for perpetrators. The results also suggest that an appetitive aggression can inhibit PTSD and trauma-related symptoms in perpetrators and prevent perpetrators from getting traumatised by their own atrocities.
Full Text Available Martin Luther King Jr understood the link between individual violence at home and state violence abroad. In part of his message that is often downplayed, he told an audience at Riverside Church, New York in 1967 that the promotion of nonviolent direct action (or the prevention of violent extremism among young Americans depended on opposing the violence of US foreign policy in places like Vietnam. Arun Kundnani ends his book arguing this point remains as valid today in the global war on terror. Indeed, in many ways, the material presented in the book paints a depressingly familiar picture of state secrecy and surveillance, the normalisation of preventative measures in the post-9/11 era, governments instilling fear and anxiety across populations, and the criminalisation of formerly lawful activities. It is now beyond dispute that these developments have eroded human rights and civil liberties in Western societies. But they have also impinged, more broadly, upon social relations and political processes. Not surprisingly, this has impacted Muslim communities the most because relations of trust have been eroded in the domestic war on terror.

In the past 2 decades, correlational and experimental studies have found a positive association between violent video game play and aggression. There is less evidence, however, to support a long-term relation between these behaviors. This study examined sustained violent video game play and adolescent aggressive behavior across the high school years and directly assessed the socialization (violent video game play predicts aggression over time) versus selection hypotheses (aggression predicts violent video game play over time). Adolescents (N = 1,492, 50.8% female) were surveyed annually from Grade 9 to Grade 12 about their video game play and aggressive behaviors. Nonviolent video game play, frequency of overall video game play, and a comprehensive set of potential 3rd variables were included as covariates in each analysis. Sustained violent video game play was significantly related to steeper increases in adolescents' trajectory of aggressive behavior over time. Moreover, greater violent video game play predicted higher levels of aggression over time, after controlling for previous levels of aggression, supporting the socialization hypothesis. In contrast, no support was found for the selection hypothesis. Nonviolent video game play also did not predict higher levels of aggressive behavior over time. Our findings, and the fact that many adolescents play video games for several hours every day, underscore the need for a greater understanding of the long-term relation between violent video games and aggression, as well as the specific game characteristics (e.g., violent content, competition, pace of action) that may be responsible for this association.

Research with violent offenders has consistently shown impaired recognition of other's facial expressions of emotion. However, the extent to which similar problems can be observed among sexual offenders remains unknown. Using a computerized task, we presented sexual and violent offenders, and non-offenders, with male and female expressions of anger, disgust, fear, happiness, sadness, and surprise, morphed with neutral expressions at varying levels of intensity (10, 55, and 90% expressive). Based on signal detection theory, we used hit rates and false alarms to calculate the sensitivity index d-prime (d') and criterion (c) for each emotional expression. Overall, sexual offenders showed reduced sensitivity to emotional expressions across intensity, sex, and type of expression, compared with non-offenders, while both sexual and violent offenders showed particular reduced sensitivity to fearful expressions. We also observed specific effects for high (90%) intensity female faces, with sexual offenders showing reduced sensitivity to anger compared with non-offenders and violent offenders, and reduced sensitivity to disgust compared with non-offenders. Furthermore, both sexual and violent offenders showed impaired sensitivity to high intensity female fearful expressions compared with non-offenders. Violent offenders also showed a higher criterion for classifying moderate and high intensity male expressions as fearful, indicative of a more conservative response style, compared with angry, happy, or sad. These results suggest that both types of offender show problems in emotion recognition, and may have implications for understanding the inhibition of violent and sexually violent behaviors.

Past aggression is a potent predictor of future aggression and informs the prediction of violent criminal recidivism. However, aggression is a heterogeneous construct and different types of aggression may confer different levels of risk for future violence. In this prospective study of 91 adults in a pretrial diversion program, we examined a) premeditated versus impulsive aggression in the prediction of violent recidivism during a one-year follow-up period, and b) whether either type of aggression would have incremental validity in the prediction of violent recidivism after taking into account frequency of past general aggression. Findings indicate that premeditated, but not impulsive, aggression predicts violent recidivism. Moreover, premeditated aggression remained a predictor of recidivism even with general aggression frequency in the model. Results provide preliminary evidence that the assessment of premeditated aggression provides relevant information for the management of violent offenders. PMID:25043811

In the United States, sexually violent predator (SVP) commitment statutes generally require assessment of an offender's risk of subsequent sexual violence. Current actuarial methods for predicting sexual reoffending were actually designed to predict something else-charges or convictions for offenses deemed sexual based on information obtained from police "rapsheets" alone. This study examined the referral and past offenses of 177 sex offenders. Results showed that police rapsheets (and data based on them) underestimated the number and severity of sexually motivated violent offenses for which sex offenders were actually apprehended. Rapsheet violent offenses seemed a more accurate index of the conduct addressed by SVP legislation than were rapsheet sex offenses. We suggest that, when evaluating sex offenders for SVP status, actuarial instruments designed to predict violent recidivism (as measured by rapsheet violent reoffenses) might be preferable to those designed to predict sexual recidivism (as measured by rapsheet sexual reoffenses).

While prior literature generally supports the connection between child maltreatment and violent offending in adolescence and early adulthood for general population samples, less is known about the relationship between child maltreatment and the frequency of violent offending among serious juvenile offenders. As a result, few studies have examined whether the effects of child maltreatment on the frequency of violent offending are mediated by other social processes, as developmental models of aggression and violence would suggest. To examine this issue, self-report data on child maltreatment, general delinquency risk factors, and violent offending were collected from 3,694 juveniles confined to 48 correctional institutions. Results from a series of negative binomial regression models indicated that the relationship between child maltreatment and the frequency of violent offending was mediated by social risk factors. The implications of these findings for theory and practice are discussed.

Few researchers have explored future educational aspirations as a promotive factor against exposure to community violence in relation to adolescents' violent behavior over time. The present study examined the direct and indirect effect of exposure to community violence prior to 9th grade on attitudes about violence and violent behavior in 12th grade, and violent behavior at age 22 via 9th grade future educational aspirations in a sample of urban African American youth (n = 681; 49% male). Multi-group SEM was used to test the moderating effect of gender. Exposure to violence was associated with lower future educational aspirations. For boys, attitudes about violence directly predicted violent behavior at age 22. For boys, future educational aspirations indirectly predicted less violent behavior at age 22. Implications of the findings and suggestions for future research are discussed. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

Violent crimes are rarely considered a public health problem or investigated using epidemiological methods. But patterns of violent crime and other health conditions are often affected by similar characteristics of the built environment. In this paper, methods and perspectives from spatial epidemiology are used in an analysis of violent crimes in San Antonio, TX. Bayesian statistical methods are used to examine the contextual influence of several aspects of the built environment. Additionally, spatial regression models using Bayesian model specifications are used to examine spatial patterns of violent crime risk. Results indicate that the determinants of violent crime depend on the model specification, but are primarily related to the built environment and neighborhood socioeconomic conditions. Results are discussed within the context of a rapidly growing urban area with a diverse population. Copyright © 2011 Elsevier Ltd. All rights reserved.

Violence is a pervasive problem in the United States. Toys, far from trivial playthings, are a reflection of society, including its beliefs and values. The purpose of this study was to describe the extent to which violent toys are marketed in online weekly flyers of popular retailers, how the violence is manifested, and whether violent toys are marketed differentially to boys and girls. For this cross-sectional observational study, online circulars from 5 major retailers were downloaded and examined each week for 14 weeks during the fall of 2014. For each retailer, the total number of toys, as well as the total number of violent and non-violent toys, was recorded. In addition, each violent toy was categorized into one of five groups: picturing a figure with a weapon, a figure with intent to strike (with fists drawn or an angry face), a toy with a violent name, a toy that was a weapon itself, or a set of toys that included two or more of these criteria. A total number of 3,459 toys were observed, of which 1,053 (30%) were deemed violent. Of the violent toys, 95% were marketed to boys (n=1,003) versus 5% to girls (n=50). The most prevalent violent category was a figure with a weapon such as a sword, knife or gun (29%), followed by figures with fists out and aggressive faces (26%). Parents should be mindful of toy retailer‟s marketing of violent toys, especially toward boys, and the potential for those toys to de-sensitize their children to violence.

The aim of this study was to determine the frequency and extent of brain anomalies in a large sample of incarcerated violent offenders not previously considered neuropsychiatrically ill, in comparison with non-violent offenders and non-offending controls. MRI and CT brain scans from 287 male prison inmates (162 violent and 125 non-violent) not diagnosed as mentally ill before that were obtained due to headache, vertigo or psychological complaints during imprisonment were assessed and compared to 52 non-criminal controls. Brain scans were rated qualitatively with respect to evidence of structural brain damage. Each case received a semiquantitative rating of "normal" (=0), "questionably abnormal" (=1) or "definitely abnormal" (=2) for the lateral ventricles, frontal/parietal cortex and medial temporal structures bilaterally as well as third ventricle. Overall, offenders displayed a significantly higher rate of morphological abnormality, with the violent offenders scoring significantly higher than non-violent offenders and controls. This difference was statistically detectable for frontal/parietal cortex, medial temporal structures, third ventricle and the left but not the right lateral ventricle. The remarkable prevalence of brain pathology in convicted violent prisoners detectable by neuroradiological routine assessment not only highlights the importance of frontal and temporal structures in the control of social, and specifically of violent behaviour, but also raises questions on the legal culpability of violent offenders with brain abnormalities. The high proportion of undetected presence of structural brain damage emphasizes the need that in violent criminals, the comprehensive routine neuropsychiatric assessment usually performed in routine forensic psychiatric expertises should be complemented with brain imaging.

To verify whether affective relationships involving violence are associated with increased risk of sexually transmitted diseases (STDs), including AIDS, we conducted a survey among youth 14 to 22 years of age residing in two low-income communities in Rio de Janeiro, Brazil. We used a qualitative methodology with focal groups and individual interviews. Violence is part of the routine among these youth in both their community and families. The following factors were associated with violence in interpersonal relations: lack of money, unemployment, drug and alcohol use, jealousy, and infidelity. The young people reported that condom use is not negotiated with violent partners, resulting in increased risk of STD/AIDS. The results indicate that violence is multi-factorial, and when present in interpersonal relationships it intervenes negatively in relation to protection against STD/AIDS.

Full Text Available Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual’s inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed to protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis, we show here in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming nonrelatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1 the dispersal of offenders and their kin and (2 sexual assault frequency (as a window on kin discrimination. Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses. These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of nonrelatives.

Violent video game playing has been linked to a wide range of negative outcomes, especially in adolescents. In the present research, we focused on a potential determinant of adolescents' willingness to play violent video games: social exclusion. We also tested whether exclusion can predict increased aggressiveness following violent video game playing. In two experiments, we predicted that exclusion could increase adolescents' preferences for violent video games and interact with violent game playing fostering adolescents' aggressive inclinations. In Study 1, 121 adolescents (aged 10-18 years) were randomly assigned to a manipulation of social exclusion. Then, they evaluated the violent content of nine different video games (violent, nonviolent, or prosocial) and reported their willingness to play each presented video game. The results showed that excluded participants expressed a greater willingness to play violent games than nonviolent or prosocial games. No such effect was found for included participants. In Study 2, both inclusionary status and video game contents were manipulated. After a manipulation of inclusionary status, 113 adolescents (aged 11-16 years) were randomly assigned to play either a violent or a nonviolent video game. Then, they were given an opportunity to express their aggressive inclinations toward the excluders. Results showed that excluded participants who played a violent game displayed the highest level of aggressive inclinations than participants who were assigned to the other experimental conditions. Overall, these findings suggest that exclusion increases preferences for violent games and that the combination of exclusion and violent game playing fuels aggressive inclinations. © 2017 Wiley Periodicals, Inc.

To promote a critical approach on the conceptualisation of domestic violence by investigating the experience of abuse on the part of men who are victims of domestic violence by their female partners. Media attention and prevention programmes relating to domestic violence have mainly focused on women as the victims and men as the perpetrators. The underlying idea is that violence is predominantly physical and a prerogative of men. This conceptualisation of violence reduces the opportunities for the consideration of different modalities of abuse. Discourse analysis within a qualitative approach. Semistructured interviews with 20 Italian men who claimed to have been abused by their female partners were conducted via Skype and analysed with the software atlas.ti. The grounded theory methodology was used to avoid imposing external points of view. Personal data were collected; in particular, their occupational level was compared to their partners' to assess the social power within the couple. Because of their strong endorsement of social and cultural values, participants showed a protective attitude towards their partners and imputed their violent acts to fragility or an external condition. Emotional distress emerged due to the isolation and subsequent inability to seek help. Although the physical violence reported is severe, the psychological violence was indicated as more damaging. Gaining an understanding of how men experience domestic abuse offers an opportunity to provide better prevention and intervention for them and other family members at risk of abuse. The study identifies gaps in service provision generated by a lack of information or perceived prejudice towards abused men. The role of the nurse in supporting male victims is discussed, and future applications for treatments and prevention plans are proposed. © 2016 John Wiley & Sons Ltd.

Aggressive and violent behaviour in children and adolescents can be associated with physical and psychological health effects continuing into adulthood. Early programs for violence prevention in childhood and adolescence are intended to prevent or reduce aggressive behaviour in order to decrease the risk for short- and long-term developmental impairments. In a literature review, research findings on prevalence, typical courses of development, and predictors of violent behavior in childhood are first summarized and compared with findings on the frequency, developmental course, and consequences of youth violence. International and German programs for violence prevention in children and adolescents are presented in the context of various settings (family, school, community), target groups (primary vs. secondary prevention) as well as target variables (universal vs. specific). Empirical findings on efficacy testing of violence prevention programs are described and discussed. The presented findings stress the relevance and potential of services for violence prevention for children and adolescents, but also demonstrate the challenges and gaps.

Currently violent video games are among the most popular video games played by consumers, most specifically First-Person Shooters (FPS. Technological advancements in game play experience including the ability to play online has accounted for this increase in popularity. Previous research, utilising the General Aggression Model (GAM, has identified that violent video games increase levels of aggression. Little is known, however, as to the effect of playing a violent video game online. METHODS/PRINCIPAL FINDINGS: Participants (N = 101 were randomly assigned to one of four experimental conditions; neutral video game--offline, neutral video game--online, violent video game--offline and violent video game--online. Following this they completed questionnaires to assess their attitudes towards the game and engaged in a chilli sauce paradigm to measure behavioural aggression. The results identified that participants who played a violent video game exhibited more aggression than those who played a neutral video game. Furthermore, this main effect was not particularly pronounced when the game was played online. CONCLUSIONS/SIGNIFICANCE: These findings suggest that both playing violent video games online and offline compared to playing neutral video games increases aggression.

Ecological models depict violent injuries against women being influenced by both individual and environmental characteristics. However, only few studies examined the association between regional variables and the likelihood of violent injuries. Our study is a preliminary assessment of the impact of regional variables on the likelihood that a woman has experienced violent injuries. Participants were 16 866 urban residents, who were identified through a multi-stage sampling process conducted in 21 Chinese cities. Out of the sampled population, 8071 respondents were female. Subsequent analyses focused solely on the female sample. Multilevel logistic regression analyses were performed to examine regional variation in violent injuries. Prevalence of violent injuries against women is 10.7% (95% CI: 7.8%, 15.5%). After controlling for individual-level characteristics, higher regional male-female ratio (OR: 1.97, P population growth rate (OR: 4.12, P unemployment rate (OR: 2.45, P < 0.01) were all associated with an elevated risk of violent injuries among Chinese women caused by physical attack. The results suggest violent injuries among Chinese women caused by physical attack have become an important social and public health problem. The findings point to the importance of developing effective health policies, laws and interventions that focuses on the unequal economic development between different regions. © The Author 2015.

It is a widespread concern that violent video games promote aggression, reduce pro-social behaviour, increase impulsivity and interfere with cognition as well as mood in its players. Previous experimental studies have focussed on short-term effects of violent video gameplay on aggression, yet there are reasons to believe that these effects are mostly the result of priming. In contrast, the present study is the first to investigate the effects of long-term violent video gameplay using a large battery of tests spanning questionnaires, behavioural measures of aggression, sexist attitudes, empathy and interpersonal competencies, impulsivity-related constructs (such as sensation seeking, boredom proneness, risk taking, delay discounting), mental health (depressivity, anxiety) as well as executive control functions, before and after 2 months of gameplay. Our participants played the violent video game Grand Theft Auto V, the non-violent video game The Sims 3 or no game at all for 2 months on a daily basis. No significant changes were observed, neither when comparing the group playing a violent video game to a group playing a non-violent game, nor to a passive control group. Also, no effects were observed between baseline and posttest directly after the intervention, nor between baseline and a follow-up assessment 2 months after the intervention period had ended. The present results thus provide strong evidence against the frequently debated negative effects of playing violent video games in adults and will therefore help to communicate a more realistic scientific perspective on the effects of violent video gaming.

It is well known that violent video games increase aggression, and that stress increases aggression. Many violent video games can be stressful because enemies are trying to kill players. The present study investigates whether violent games increase aggression by inducing stress in players. Stress was measured using cardiac coherence, defined as the synchronization of the rhythm of breathing to the rhythm of the heart. We predicted that cardiac coherence would mediate the link between exposure to violent video games and subsequent aggression. Specifically, we predicted that playing a violent video game would decrease cardiac coherence, and that cardiac coherence, in turn, would correlate negatively with aggression. Participants (N = 77) played a violent or nonviolent video game for 20 min. Cardiac coherence was measured before and during game play. After game play, participants had the opportunity to blast a confederate with loud noise through headphones during a reaction time task. The intensity and duration of noise blasts given to the confederate was used to measure aggression. As expected, violent video game players had lower cardiac coherence levels and higher aggression levels than did nonviolent game players. Cardiac coherence, in turn, was negatively related to aggression. This research offers another possible reason why violent games can increase aggression-by inducing stress. Cardiac coherence can be a useful tool to measure stress induced by violent video games. Cardiac coherence has several desirable methodological features as well: it is noninvasive, stable against environmental disturbances, relatively inexpensive, not subject to demand characteristics, and easy to use. © 2012 Wiley Periodicals, Inc.
Full Text Available Abstract Background Area-level socioeconomic disparities have long been associated with adverse pregnancy outcomes. Crime is an important element of the neighborhood environment inadequately investigated in the reproductive and public health literature. When crime has been used in research, it has been variably defined, resulting in non-comparable associations across studies. Methods Using geocoded linked birth record, crime and census data in multilevel models, this paper explored the relevance of four spatial violent crime exposures: two proximal violent crime categorizations (count of violent crime within a one-half mile radius of maternal residence and distance from maternal residence to nearest violent crime and two area-level crime categorizations (count of violent crimes within a block group and block group rate of violent crimes for adverse birth events among women in living in the city of Raleigh NC crime report area in 1999–2001. Models were adjusted for maternal age and education and area-level deprivation. Results In black and white non-Hispanic race-stratified models, crime characterized as a proximal exposure was not able to distinguish between women experiencing adverse and women experiencing normal birth outcomes. Violent crime characterized as a neighborhood attribute was positively associated with preterm birth and low birth weight among non-Hispanic white and black women. No statistically significant interaction between area-deprivation and violent crime category was observed. Conclusion Crime is variably categorized in the literature, with little rationale provided for crime type or categorization employed. This research represents the first time multiple crime categorizations have been directly compared in association with health outcomes. Finding an effect of area-level violent crime suggests crime may best be characterized as a neighborhood attribute with important implication for adverse birth outcomes.

Full Text Available Objective to study the decisionmaking process in highriskforviolence situations. Methods formallegal sociological method of hierarchical generalized linear modeling. Results criminological research has favored the rational choice perspective in studying offender decision making. However this theoretical approach does not take into account the complex interplay of situational cognitive emotional and person factors that likely influence criminal decision making. To that end the current study examines decision making in highriskforviolence situations focusing on social information processing and emotional state variables. The current study utilizes a sample of 236 newly incarcerated jailed inmates who provide personal level data and situational reports of violent and avoided violence situations n 466. Scientific novelty the findings for the first time show that several situational social information processing and emotion variables such as intent interpretation goal and response generation are significant predictors of the escalation of violence hence increasing the probability of committing a crime. Practical significance the main provisions and conclusions of the article can be used in scientific and lawenforcement activities when considering the issues of identifying and eliminating the reasons and conditions of crime committing as well as with influencing the individuals in order to prevent crimes or antisocial behavior.

While suicide notes can offer insights into the causes of suicide and clues for prevention, there is disagreement regarding the degree to which note leavers are representative of the general population of suicides. Previous relevant research on the United States is marked by a series of limitations: small local samples, an over focus on demographic constructs, and lack of multivariable analysis. This study uses a large national sample, a wide range of predictor variables, and multivariable statistical techniques to estimate more reliable similarities and differences between note leavers and other suicides. All data are taken from the National Violent Death Reporting System, which covers 17 states. A total of 9,048 note writers were compared to 21,522 other suicides in terms of 39 variables. In both bivariable (32/39 variables) and multivariable analyses (30/39 variables), note leavers differed from other suicides in most demographic variables, stressful life events, psychiatric issues, and methods of suicide. The national evidence suggests that caution be exercised in generalizing patterns found among writers of suicide notes to suicides in general. This is the first analysis of suicide notes using US data on the issue. © 2016 The American Association of Suicidology.

During the past few decades, violent mass shooting in Sweden has increased rapidly. In the 36 years between 1960 and 1995, fourteen such occasions were recorded, during which 32 people were killed and 57 were wounded. The 14 offenders were men between the ages of 17 and 61 years. In the 20 years from 1960 to 1979, five shootings were committed by five offenders, leaving 10 dead and 13 wounded; in the 16 years between 1980 and 1995, there were nine different shootings committed by nine offenders, with 22 dead and 44 wounded. Seven of the shootings were classified as mass shootings, six as spree shootings, and one as a serial shooting. In all but four of these cases, the firearms used were illegal weapons. The four legal firearms belonged to an unemployed young laborer, an officer, a former United Nations (U.N.) soldier, and a member of the Swedish military volunteer corps. Of those killed, 68.8% were strangers to the offender; among the wounded, the corresponding figure was 89.5%. Profiles of the offenders and of the victims were studied. The psychiatric diagnoses among the offenders and the measures taken to prevent the increase in mass shooting in Sweden are presented.

The National Violent Death Reporting System (NVDRS) is a United States Centers for Disease Control and Prevention (CDC) database of violent deaths from 2003 to the present. The NVDRS collects information from 32 states on several types of violent deaths, including suicides, homicides, homicides followed by suicides, and deaths resulting from child maltreatment or intimate partner violence, as well as legal intervention and accidental firearm deaths. Despite the availability of data from police narratives, medical examiner reports, and other sources, reliably finding the cases of murder-suicide in the NVDRS has proven problematic due to the lack of a unique code for murder-suicide incidents and outdated descriptions of case-finding procedures from previous researchers. By providing a description of the methods used to access to the NVDRS and coding procedures used to decipher these data, the authors seek to assist future researchers in correctly identifying cases of murder-suicide deaths while avoiding false positives. © 2015 American Academy of Forensic Sciences.

Past research has provided abundant evidence that playing violent video games increases aggressive behavior. So far, these effects have been explained mainly as the result of priming existing knowledge structures. The research reported here examined the role of denying humanness to other people in accounting for the effect that playing a violent video game has on aggressive behavior. In two experiments, we found that playing violent video games increased dehumanization, which in turn evoked aggressive behavior. Thus, it appears that video-game-induced aggressive behavior is triggered when victimizers perceive the victim to be less human.

The aim of this survey was to identify predictors of suicide attempts that immediately followed a violent crime in patients with schizophrenia. Documentations of patients diagnosed with schizophrenia and released in a 10 years period from the National Institute of Forensic Psychiatry were reviewed. Twenty-six out of 223 patients attempted suicide after the violent crime. The young age of the victim, and living in partnership were those factors differentiating suicidal violent offenders from their non-suicidal counterparts. Copyright © 2015 Elsevier Ireland Ltd.

Full Text Available This paper intents to show that deep social transformations that took place in the Soviet Union, between middle 80s and middle 90s during XXth. century, provoqued a significant increase in violent deaths rates (suicides, homicides and accidents. Our study follows a theoretical perspective based on Durkheim ideas , that try to explain variations in violent deaths rates analyzing changes in the intensity and nature of social relationships. The analysis of evolution of specific rates by region, sex and age allowed us to verify that groups more directly affected by social transformations were those that also presented the highest rates in the proportion of violent deaths.

This study used baseline data on recently released paroled men who are homeless (N=157), residing in a residential drug treatment program, and enrolled in a longitudinal study to examine personal, developmental, and social correlates of parolees who are homeless and who have committed serious violent offenses. Having experienced childhood sexual abuse, poor parental relationships, and early-onset incarceration (prior to 21 years of age) were important correlates of serious violent crimes. These findings highlight the need for interventions that address offenders' prior adult and childhood victimization and suggest that policies for reentering violent offenders should encompass an understanding of the broader family contexts in which these patterns of maltreatment often occur.
SOHO's scientists are impressed by the vigorous action that they see going on every day, because the Sun is in the very quietest phase of its eleven-year cycle of activity. To ground-based observatories it appears extremely calm just now. The early indications of SOHO's performance amply justify the creation of a sungazing spacecraft capable of observing ultraviolet emissions that are blotted out by the Earth's atmosphere. Apart from the imager, two ultraviolet spectrometers and an ultraviolet coronagraph (an imager for the outer atmosphere) are busy analysing the violent processes at a wide range of wavelengths. Between them, these instruments should cure long-lasting ignorance concerning the Sun, especially about why the atmosphere is so hot and what drives the solar wind that blows non-stop into the Solar System. Scientists from other experimental teams use SOHO to explore the Sun from its deep interior to the far reaches of the solar wind. They have watched the supposedly quiet Sun belching huge masses of gas into space. They have mapped a hole burnt by the solar wind in a breeze of gas coming from the stars. And they have detected currents of gas flowing just below the visible surface. SOHO is a project of international cooperation between the European Space Agency and NASA. The spacecraft was built in Europe and instrumented by scientists on both sides of the Atlantic. NASA launched SOHO on 2 December 1995, and also provides the ground stations and an operations centre near Washington. The first results are the more remarkable because SOHO arrived at its vantage point 1,500,000 kilometres out in space only in February, and formally completed its commissioning on 16 April. It has a long life ahead of it. All scientific instruments are working well. The luminosity oscillation imager belonging to the VIRGO experiment had trouble with its lens cover. When opened, the cover rebounded on its hinges and closed again. Commands were devised that gave a shorter impulse

Previous research has shown that playing violent video game exposure can increase aggressive thoughts, aggressive feelings, and physiological arousal. This study compared the effects that playing a realistic violent, unrealistic violent, or nonviolent video game for 45 min has on such variables. For the purpose of this study, realism was defined as the probability of seeing an event in real life. Participants (N=74; 39 male, 35 female) played either a realistic violent, unrealistic violent, or nonviolent video game for 45 min. Aggressive thoughts and aggressive feelings were measured four times (every 15 min), whereas arousal was measured continuously. The results showed that, though playing any violent game stimulated aggressive thoughts, playing a more realistic violent game stimulated significantly more aggressive feelings and arousal over the course of play.

Although people typically avoid engaging in antisocial or taboo behaviors, such as cheating and stealing, they may succumb in order to maximize their personal benefit. Moreover, they may be frustrated when the chance to commit a taboo behavior is withdrawn. The present study tested whether the desire to commit a taboo behavior, and the frustration from being denied such an opportunity, increases attraction to violent video games. Playing violent games allegedly offers an outlet for aggression prompted by frustration. In two experiments, some participants had no chance to commit a taboo behavior (cheating in Experiment 1, stealing in Experiment 2), others had a chance to commit a taboo behavior, and others had a withdrawn chance to commit a taboo behavior. Those in the latter group were most attracted to violent video games. Withdrawing the chance for participants to commit a taboo behavior increased their frustration, which in turn increased their attraction to violent video games.

Three experiments examined the effects of rewarding and punishing violent actions in video games on later aggression-related variables. Participants played one of three versions of the same race-car video game: (a) a version in which all violence was rewarded, (b) a version in which all violence was punished, and (c) a nonviolent version. Participants were then measured for aggressive affect (Experiment 1), aggressive cognition (Experiment 2), and aggressive behavior (Experiment 3). Rewarding violent game actions increased hostile emotion, aggressive thinking, and aggressive behavior. Punishing violent actions increased hostile emotion, but did not increase aggressive thinking or aggressive behavior. Results suggest that games that reward violent actions can increase aggressive behavior by increasing aggressive thinking.

Full Text Available AIMS - The purpose of this population-based study was to explore the relationship between gambling and violent behaviour and attitudes towards violence among 14- and 16-year-old adolescents. DESIGN - A national survey was conducted in Finland in 2011. The main measures in our study were gambling frequency and number of reported gambling-related harms. Their associations with violent behaviours and attitudes towards violence were studied using multinomial logistic regression and negative binomial regression. RESULTS - 47.1% of adolescents had gambled during the past six months and 13.2% of them had experienced gambling-related harms. Both gambling frequency and the number of gambling-related harms were linked to violent behaviour as well as to positive attitudes towards violence. Adolescents who engaged in gambling on a daily basis and/ or experienced gambling harms had the highest risk. CONCLUSIONS - Health promotion efforts among gamblers should take into account their increased risk for violent behaviour.

The impact of violent video games (VVGs) on youth remains unclear given inconsistent results in past literature. Most previous experimental studies have been done with college students, not youth. The current study examined the impact of VVGs in an experimental study of teens (12-18). Participants were randomized to play either a violent or non-violent video game. Teens also reported their levels of stress and hostility both before and after video game play. Hostility levels neither decreased nor increased following violent game play, and Bayesian analyzes confirmed that results are supportive of the null hypothesis. By contrast, VVG exposure increased stress, but only for girls. The impact of VVGs on teen hostility is minimal. However, players unfamiliar with such games may find them unpleasant. These results are put into the context of Uses and Gratifications Theory with suggestions for how medical professionals should address the issue of VVG play with concerned parents.

Although research has confirmed that violent losses can exacerbate grief reactions, few investigations have explored underlying mechanisms. In this study, the authors used a dataset on bereaved spouses and bereaved parents at 4- and 18-months postloss to examine the mediating effects of self-worth and worldviews (benevolence and meaningfulness beliefs). Persons bereaved by violent causes had significantly more posttraumatic stress disorder (PTSD), grief, and depression symptoms at 4- and 18-months postloss than persons bereaved by natural causes. Moreover, self-worth but not worldviews mediated the effects of violent loss on PTSD and depression symptoms cross sectionally and PTSD symptoms longitudinally. Findings underscore that self-views are a critical component of problematic reactions to violent loss, but fail to support the role of "shattered" worldviews.

This study explores the nature and outcome of violent incidents experienced by child, adolescent, adult, and elderly victims. Data from the National Incident-Based Reporting System (NIBRS) are used to determine whether there are differences in the situational characteristics-including location, time of day, weapons, and the victim-offender relationship-of violent victimization experiences across the 4 age groups, including whether situational characteristics influence the likelihood of victim injury. Results indicate that victim injury is most prevalent among adult victims and that the situational characteristics of violent incidents vary by victim age, as do the correlates of victim injury. These findings suggest that of the nature of violent victimization should be examined within the context of victim age, and supports research by scholars who have proposed a model of developmental victimology to identify age-specific victimization patterns.

Violent offending by veterans of the Iraq and Afghanistan conflicts is a cause for concern and there is much public debate about the proportion of ex-military personnel in the criminal justice system for violent offences. Although the psychological effects of conflict are well documented, the potential legacy of violent offending has yet to be ascertained. We describe our use of criminal records to investigate the effect of deployment, combat, and post-deployment mental health problems on violent offending among military personnel relative to pre-existing risk factors. In this cohort study, we linked data from 13,856 randomly selected, serving and ex-serving UK military personnel with national criminal records stored on the Ministry of Justice Police National Computer database. We describe offending during the lifetime of the participants and assess the risk factors for violent offending. 2,139 (weighted 17.0%) of 12,359 male UK military personnel had a criminal record for any offence during their lifetime. Violent offenders (1,369 [11.0%]) were the most prevalent offender types; prevalence was highest in men aged 30 years or younger (521 [20.6%] of 2,728) and fell with age (164 [4.7%] of 3027 at age >45 years). Deployment was not independently associated with increased risk of violent offending, but serving in a combat role conferred an additional risk, even after adjustment for confounders (violent offending in 137 [6.3%] of 2178 men deployed in a combat role vs 140 (2.4%) of 5,797 deployed in a non-combat role; adjusted hazard ratio 1.53, 95% CI 1.15-2.03; p=0.003). Increased exposure to traumatic events during deployment also increased risk of violent offending (violent offending in 104 [4.1%] of 2753 men with exposure to two to four traumatic events vs 56 [1.6%] of 2944 with zero to one traumatic event, 1.77, 1.21-2.58, p=0.003; and violent offending in 122 [5.1%] of 2582 men with exposure to five to 16 traumatic events, 1.65, 1.12-2.40, p=0.01; test for trend
This stunning composite image shows the components of the galaxy cluster RX J0603.3+4214, located at a redshift of z=0.225. This image contains Chandra X-ray data (red), radio data from the Giant Metrewave Radio Telescope (green), and optical from the Subaru Telescope (background). The shape of the enormous (6.5 million light-years across!) radio relic, shown in green, gives this collection of galaxies its nickname: the Toothbrush Cluster. A team of scientists led by Myungkook James Jee (Yonsei University and University of California, Davis) used Hubble and Subaru to study weak gravitational lensing by the Toothbrush Cluster, in order to determine how the clusters mass is distributed. Jee and collaborators found that most of the dark-matter mass is located in two large clumps on a north-south axis (shown by the white contours overlaid on the image), suggesting that the Toothbrush Cluster is the result of a past merger between two clusters. This violent merger is likely what caused the enormous Toothbrush radio relic. Check out the paper below for more information!CitationM.

Full Text Available This paper unveils the revolutionary potential incarnated in the post-9/11 transformed figure of the cinematic zombie. It is my contention that zombies, through their cinematic (revolution, came to embody Deleuze and Guattari’s vision of the nomad war machine. Zombie films are used as a vehicle for addressing the tension between the hegemonic fear of the violent multitude in revolt and the counter-hegemonic liberatory potential of the rising masses. It is impossible to achieve a final resolution between these contradicting tendencies since the narrative structure of zombie films remains open-ended. The characteristics of the zombies and the meaning ascribed to them transform over time but they also maintain a continuity with a difference with the previous expressions of the monstrous. The monstrous characteristics which have pertained since George A. Romero’s paradigm shift in the 1960s (the zombifying contagion, violence and swarm attacks, joined with the new features appearing in the American zombie cinema of the new millennium, formulate a response to the manifest and latent violence of the State apparatus.
Full Text Available The management of aggressive behaviour has always been a criticai issue in psychiatry. Finding measures that can be used to accurately predict the likelihood of assaultative behaviour and thus ensure timeous appropriate pharmacological management remains a dilemma. The study objective was to investigate the naturalistic, pharmacological management of inpatient aggressive behaviour in a group of 50 schizophrenic subjects with a view to determine: (1 whether a presenting history of recent violence lead to altered pharmacological management and (2 whether the NOSIE could be regarded as a useful assessment tool with regards to inpatient behaviour management. No significant difference could be demonstrated between the 2 subsets of subjects (history of violence vs none with respect to total doses of medication administered. No statistical correlation could be found between the total NOSIE score and the dose of psychotropic medication used. The relationship between a subset of NOSIE-items and the total dose of medication was more complex and a clear linear relationship could be demonstrated for a total score of 0 to 5. In this particular ward setting a presenting history of recent violent behaviour did not influence the administration of medication and neither could the clinical judgement employed by the nursing staff to manage inpatient behaviour be captured by the NOSIE. However, a five-item subset of the NOSIE with questions relating to aggression and irritability warrants further scrutiny in this regard.

This study investigated prison homicide perpetrators through the lens of the career criminal perspective. Prison homicide, while a rare event, has critical implications for the prison environment. Despite its importance as a form of institutional violence that must be addressed, only four studies in the past five decades have explored the characteristics of homicide perpetrators/victims, the motives, and circumstances of the crime. The goal of the current study was to develop a better understanding of prison homicide by examining 54 perpetrators who committed 37 inmate homicides over 40 years in a mid-Western state prison system. Results showed that prison homicides typically involved a younger male inmate perpetrator, acting independently, murdering an older inmate, in his cell, by stabbing or beating the victim during an altercation. Perpetrators, in comparison with victims and prisoners in general, had a record indicating more prior community homicides, elevated institutional risk scores, and higher rates of serious and assaultive prison misconduct, all indicative of prior community and prison maladjustment. Consistent with career criminal research, prison homicide perpetrators constitute a small but distinct subset of habitually deviant criminals that perpetrate high rates of criminal and violent behavior regardless of context.
Schizophrenia without any comorbidity confers a modest, but statistically significant elevation of the risk for violence. That risk is considerably increased by comorbid antisocial personality disorder or psychopathy as well as by comorbid substance use disorders. These comorbidities are frequent. Conduct disorder and conduct disorder symptoms elevate the risk for aggressive behavior in patients with schizophrenia. Violence among adults with schizophrenia may follow at least two distinct pathways-one associated with premorbid conditions, including antisocial conduct, and another associated with the acute psychopathology of schizophrenia. Aggressive behavior in bipolar disorder occurs mainly during manic episodes, but it remains elevated in euthymic patients in comparison with controls. The risk of violent behavior is increased by comorbidity with borderline personality disorder, antisocial personality disorder, and substance use disorders. These comorbidities are frequent. Borderline personality disorder and bipolar disorder are related in their phenomenology and response to medication. These two disorders share a tendency to impulsiveness, and impulsive behavior, including impulsive aggression, is particularly expressed when they co-occur.
Full Text Available Violent computer games are becoming an increasingly common phenomenon of leisure activities among children and the young. Most researchers and practical educators consider them a dangerous phenomenon that encourages violence in everyday life. A kind of cyclic round goes from children who, due to a lack of sensitive communication, quickly feel certain tensions and quench them by resorting to media violence where computer games take the lead in the modern environment. Educators suggest the creation of situations where children and adolescents can speak out and express their pain in different ways. An in-depth expression of children’s and adolescents’ experiences does not only change their feelings, but extends to the changes at the level of neurobiological functioning. Adults, especially parents, help children mostly in overcoming violence if, in sensitive communication, they radiate happiness with their own lives and the ability to solve problems and give signs of unconditional acceptance and love. In such communication, children and young people re-experience their parents and other educators as strong personalities and moral authorities whom they love and respect.

The link between substance use and suicide is well established. However, little research analyzes how substance use is related to the method of suicide. This paper analyzes how specific drugs are associated with method of suicide, a critical topic because drug use bears on the etiology of suicide and may lead to policies aimed at deterring suicide. We use the COVDRS and logistic regression to examine postmortem presence of drugs among 3,389 hanging and firearm suicides in Colorado from 2004–2009. Net of demographic controls, we find that opiates are positively associated with firearms (OR: 1.92, 95% L: 1.27, 95% U: 2.86]) while antidepressants are positively associated with hanging (OR: 1.45, 95% L: 1.04, 95% U: 2.03). For cocaine and opiates, the association between drug use and violent method vary by educational attainment. Importantly, knowledge of the presence and type of specific drug is strongly associated with the method of suicide. PMID:27239069

Previous studies have reported numerous correlations between psychopathy and various personality traits, behavioural tendencies or clinical characteristics. The present study examined in greater depth the relationships between the components of psychopathy as measured by the Psychopathy Checklist-Revised (PCL-R) and intelligence as well as impulsivity. A total of ninety male violent offenders were recruited from a prison and a forensic-psychiatric hospital in Germany. All of the subjects were assessed using the PCL-R, the Barratt Impulsiveness Scale (BIS-11), and a short version of the German Wechsler Adult Intelligence Scale (WIP). As expected, a canonical correlation analysis showed a negative association between spatial intelligence and the Factor 2 subtotal on the PCL-R (reckless lifestyle/antisociality). In addition, our results agreed with the assumption of an association between impulsivity and the subtotal for PCL-R Factor 2. The positive relationship between verbal intelligence and the subtotal for Factor 1 of the PCL-R (insincere, manipulative conduct/affective deficits) vanished after controlling for educational level. The results indicate that there is a relationship between the spatial components of intelligence and the concept of psychopathy as described by Hare. This result supports the spatial impairment aetiological model of antisocial behaviour. Copyright © 2013 Elsevier Ltd. All rights reserved.

During the formation of stellar systems such as globular clusters, low-mass subcondensations which eventually form stars must retain a geometric size throughout the collapse process that is small compared to the characteristic distance separating them. If the local velocity dispersion of the subcondensations is small, the overall dimension of the system can decrease substantially before reaching a dynamical equilibrium state. The maximum collapse factor is deduced by examining the growth of the velocity dispersion and the spread in arrival times at the origin caused by local and global fluctuations. It is shown, analytically as well as in a series of N-body simulations, that the maximum reduction in the characteristic dimension of a system of N fragments with an initial homogeneous distribution subject to N exp 1/2 fluctuations is proportional to N exp 1/3. Direct physical collisions between low-mass subcondensations are therefore unlikely to occur in protoglobular clusters. The results are discussed in the context of fragmentation and violent relaxation.
Full Text Available Abstract Background High rates of repeat offending are common across nations that are socially and culturally different. Although psychiatric disorders are believed to be risk factors for violent reoffending, the available evidence is sparse and liable to bias. Method We conducted a historical cohort study in Sweden of a selected sample of 4828 offenders given community sentences who were assessed by a psychiatrist during 1988–2001, and followed up for an average of 5 years for first violent offence, death, or emigration, using information from national registers. Hazard ratios for violent offending were calculated by Cox regression models. Results Nearly a third of the sample (n = 1506 or 31.3% offended violently during follow-up (mean duration: 4.8 years. After adjustment for socio-demographic and criminal history variables, substance use disorders (hazard ratio 1.97, 95% CI, 1.40–2.77 and personality disorders (hazard ratio 1.71, 1.20–2.44 were significantly associated with an increased risk of violent offending. No other diagnoses were related to recidivism risk. Adding information on diagnoses of substance use and personality disorders to data recorded on age, sex, and criminal history improved only minimally the prediction of violent offending. Conclusion Diagnoses of substance use and personality disorders are associated with the risk of subsequent violent offending in community offenders about as strongly as are its better documented demographic and criminal history risk factors. Despite this, assessment of such disorders in addition to demographic and criminal history factors enhances only minimally the prediction of violent offending in the community.

BACKGROUND: Past research has found that playing a classic prosocial video game resulted in heightened prosocial behavior when compared to a control group, whereas playing a classic violent video game had no effect. Given purported links between violent video games and poor social behavior, this result is surprising. Here our aim was to assess whether this finding may be due to the specific games used. That is, modern games are experienced differently from classic games (more immersion in vir...

Full Text Available Several structural brain abnormalities have been associated with aggression in patients with schizophrenia. However, little is known about shared and distinct abnormalities underlying aggression in these subjects and non-psychotic violent individuals. We applied a region-of-interest volumetric analysis of the amygdala, hippocampus, and thalamus bilaterally, as well as whole brain and ventricular volumes to investigate violent (n = 37 and non-violent chronic patients (n = 26 with schizophrenia, non-psychotic violent (n = 24 as well as healthy control subjects (n = 24. Shared and distinct volumetric abnormalities were probed by analysis of variance with the factors violence (non-violent versus violent and diagnosis (non-psychotic versus psychotic, adjusted for substance abuse, age, academic achievement and negative psychotic symptoms. Patients showed elevated vCSF volume, smaller left hippocampus and smaller left thalamus volumes. This was particularly the case for non-violent individuals diagnosed with schizophrenia. Furthermore, patients had reduction in right thalamus size. With regard to left amygdala, we found an interaction between violence and diagnosis. More specifically, we report a double dissociation with smaller amygdala size linked to violence in non-psychotic individuals, while for psychotic patients smaller size was linked to non-violence. Importantly, the double dissociation appeared to be mostly driven by substance abuse. Overall, we found widespread morphometric abnormalities in subcortical regions in schizophrenia. No evidence for shared volumetric abnormalities in individuals with a history of violence was found. Finally, left amygdala abnormalities in non-psychotic violent individuals were largely accounted for by substance abuse. This might be an indication that the association between amygdala reduction and violence is mediated by substance abuse. Our results indicate the importance of structural abnormalities in aggressive

What makes virtual violence enjoyable rather than aversive? Two 2×2 experiments tested the assumption that moral disengagement cues provided by a violent video game's narrative and game play lessen users' guilt and negative affect, which would otherwise undermine players' enjoyment of the game. Experiment 1 found that users' familiarity with the violent game reduced guilt and negative affect, and enhanced enjoyment, whereas opponents' nonhuman outer appearance and blameworthiness had no effec...

Research with violent offenders has consistently shown impaired recognition of other’s facial expressions of emotion. However, the extent to which similar problems can be observed among sexual offenders remains unknown. Using a computerized task, we presented sexual and violent offenders, and non-offenders, with male and female expressions of anger, disgust, fear, happiness, sadness, and surprise, morphed with neutral expressions at varying levels of intensity (10%, 55%, and 90% expressive). ...

Several structural brain abnormalities have been associated with aggression in patients with schizophrenia. However, little is known about shared and distinct abnormalities underlying aggression in these subjects and non-psychotic violent individuals. We applied a region-of-interest volumetric analysis of the amygdala, hippocampus, and thalamus bilaterally, as well as whole brain and ventricular volumes to investigate violent (n = 37) and non-violent chronic patients (n = 26) with schizophrenia, non-psychotic violent (n = 24) as well as healthy control subjects (n = 24). Shared and distinct volumetric abnormalities were probed by analysis of variance with the factors violence (non-violent versus violent) and diagnosis (non-psychotic versus psychotic), adjusted for substance abuse, age, academic achievement and negative psychotic symptoms. Patients showed elevated vCSF volume, smaller left hippocampus and smaller left thalamus volumes. This was particularly the case for non-violent individuals diagnosed with schizophrenia. Furthermore, patients had reduction in right thalamus size. With regard to left amygdala, we found an interaction between violence and diagnosis. More specifically, we report a double dissociation with smaller amygdala size linked to violence in non-psychotic individuals, while for psychotic patients smaller size was linked to non-violence. Importantly, the double dissociation appeared to be mostly driven by substance abuse. Overall, we found widespread morphometric abnormalities in subcortical regions in schizophrenia. No evidence for shared volumetric abnormalities in individuals with a history of violence was found. Finally, left amygdala abnormalities in non-psychotic violent individuals were largely accounted for by substance abuse. This might be an indication that the association between amygdala reduction and violence is mediated by substance abuse. Our results indicate the importance of structural abnormalities in aggressive individuals.

This review addresses human capacity for movement in the context of extreme loading and with it the combined effects of metabolic, biomechanical and gravitational stress on the human body. This topic encompasses extreme duration, as occurs in ultra-endurance competitions (e.g. adventure racing...... and transcontinental races) and expeditions (e.g. polar crossings), to the more gravitationally limited load carriage (e.g. in the military context). Juxtaposed to these circumstances is the extreme metabolic and mechanical unloading associated with space travel, prolonged bedrest and sedentary lifestyle, which may...

Symptomatically, patients often present with pain, swelling, and occasionally discoloration of the hand. In the presence of chronic swelling, it may be difficult to differentiate thrombosis from lymphedema, especially in patients who have undergone mastectomy. Noninvasive testing is helpful in differentiating between these two conditions, but venography offers definitive diagnosis. More importantly, venography demonstrates the site as well as the extent of the thrombotic process. Venography of the upper extremity was first introduced in 1931. Unlike the lower extremity, the use of this simple radiographic technique to evaluate venous problems of the upper extremity has received little attention

For the conservation of crushed extremities all achievements of up-to-date traumatology are to be used. The impairement of the seriously crushed extremity displays a certain similarity to the polytraumatism involving the whole organism. This is to be taken into consideration in the surgical treatment. Conserving the vitality of the extremity deferred treatment and reconstructive operations at a later date become possible. As absolute rule must be in view that all cases are to be examined with the greatest care and individually, as regards the surgical treatment.

For roughly three decades, policymakers have sought to reduce sexual violence by reliance on a criminal justice approach in which sexually violent acts are dealt with after they occur. Recognizing that prevention efforts could be more valuable, as they work to stop the problem before it begins, researchers have begun to implement a primary…

Full Text Available BACKGROUND: Past research has found that playing a classic prosocial video game resulted in heightened prosocial behavior when compared to a control group, whereas playing a classic violent video game had no effect. Given purported links between violent video games and poor social behavior, this result is surprising. Here our aim was to assess whether this finding may be due to the specific games used. That is, modern games are experienced differently from classic games (more immersion in virtual environments, more connection with characters, etc. and it may be that playing violent video games impacts prosocial behavior only when contemporary versions are used. METHODS AND FINDINGS: Experiments 1 and 2 explored the effects of playing contemporary violent, non-violent, and prosocial video games on prosocial behavior, as measured by the pen-drop task. We found that slight contextual changes in the delivery of the pen-drop task led to different rates of helping but that the type of game played had little effect. Experiment 3 explored this further by using classic games. Again, we found no effect. CONCLUSIONS: We failed to find evidence that playing video games affects prosocial behavior. Research on the effects of video game play is of significant public interest. It is therefore important that speculation be rigorously tested and findings replicated. Here we fail to substantiate conjecture that playing contemporary violent video games will lead to diminished prosocial behavior.

Possessing a strong cultural identity has been shown to protect against mental health symptoms and buffer distress prompted by discrimination. However, no research to date has explored the protective influences of cultural identity and cultural engagement on violent offending. This paper investigates the relationships between cultural identity/engagement and violent recidivism for a cohort of Australian Indigenous people in custody. A total of 122 adults from 11 prisons in the state of Victoria completed a semi-structured interview comprising cultural identification and cultural engagement material in custody. All official police charges for violent offences were obtained for participants who were released from custody into the community over a period of 2 years. No meaningful relationship between cultural identity and violent recidivism was identified. However a significant association between cultural engagement and violent recidivism was obtained. Further analyses demonstrated that this relationship was significant only for participants with a strong Indigenous cultural identity. Participants with higher levels of cultural engagement took longer to violently re-offend although this association did not reach significance. For Australian Indigenous people in custody, 'cultural engagement' was significantly associated with non-recidivism. The observed protective impact of cultural engagement is a novel finding in a correctional context. Whereas identity alone did not buffer recidivism directly, it may have had an indirect influence given its relationship with cultural engagement. The findings of the study emphasize the importance of culture for Indigenous people in custody and a greater need for correctional institutions to accommodate Indigenous cultural considerations.

The current study adds to prior research by investigating specific (happiness, sadness, surprise, disgust, anger and fear) and general (corrugator and zygomatic muscle activity) facial reactions to violent and comedy films among individuals with varying levels of callous-unemotional (CU) traits and impulsive aggression (IA). Participants at differential risk of CU traits and IA were selected from a sample of 1225 young adults. In Experiment 1, participants (N = 82) facial expressions were recorded while they watched violent and comedy films. Video footage of participants' facial expressions was analysed using FaceReader, a facial coding software that classifies facial reactions. Findings suggested that individuals with elevated CU traits showed reduced facial reactions of sadness and disgust to violent films, indicating low empathic concern in response to victims' distress. In contrast, impulsive aggressors produced specifically more angry facial expressions when viewing violent and comedy films. In Experiment 2 (N = 86), facial reactions were measured by monitoring facial electromyography activity. FaceReader findings were verified by the reduced facial electromyography at the corrugator, but not the zygomatic, muscle in response to violent films shown by individuals high in CU traits. Additional analysis suggested that sympathy to victims explained the association between CU traits and reduced facial reactions to violent films.

While the relationship between abusive parenting and violent delinquency has been well established, the cognitive and emotional processes by which this occurs remain relatively unidentified. The objective of this work is to apply a conceptual model linking abusive parenting to the conversion of shame into blaming others and therefore to violent delinquency. A retrospective study of 112 adolescents (90 male; 22 female; ages 12-19 years; M=15.6; SD=1.4) who were incarcerated in a juvenile detention facility pending criminal charges, completed measures of exposure to abusive and nonabusive discipline, expressed and converted shame, and violent delinquency. Findings tend to confirm the conceptual model. Subjects who converted shame (i.e., low expressed shame, high blaming others) tended to have more exposure to abusive parenting and showed more violent delinquent behavior than their peers who showed expressed shame. Subjects who showed expressed shame (i.e., high expressed shame, low blaming others) showed less violent delinquency than those who showed converted shame. Abusive parenting impacts delinquency directly and indirectly through the effects of shame that is converted. Abusive parenting leads to the conversion of shame to blaming others, which in turn leads to violent delinquent behavior. For juvenile offenders, the conversion of shame into blaming others appears to contribute to pathological outcomes in relation to trauma.

Sexual orientation and gender identity (SO/GI) are not systematically recorded at time of death, limiting identification of mortality disparities in lesbian, gay, bisexual, and transgender (LGBT) people. LGBT populations are thought to have elevated risk of suicide based on high rates of reported lifetime suicide attempts. Lack of data on suicide deaths, however, hinders understanding of the prevalence and patterns of suicide among LGBT populations and development of targeted interventions and prevention programs. This report describes recent efforts to address this knowledge gap by systematically collecting SO/GI information in the investigation of suicide and other violent deaths.

As eukaryotic microbial life, ciliated protozoan may be found actively growing in some extreme condition where there is a sufficient energy source to sustain it because they are exceedingly adaptable and not notably less adaptable than the prokaryotes. However, a crucial problem in the study of ciliates in extreme environments is the lack of reliable cultivation techniques. To our knowledge, only a tiny fraction of ciliates can be cultured in the laboratory, even for a very limited period, which can partly explain the paucity of our understanding about ciliates diversity in various extremes although the interest in the biodiversity of extremophiles increased significantly during the past three decades. This mini-review aims to compile the knowledge of several groups of free-living ciliates that can be microscopically observed in extreme environmental samples, although most habitats have not been sufficiently well explored for sound generalizations. © 2014 The Author(s) Journal of Eukaryotic Microbiology © 2014 International Society of Protistologists.
Conclusions: Based on the results of the present study that indicates teenagers are less aware of the consequences of violent behavior compared to other subscales of knowledge, it is better that teenagers′ education about the violent behaviors are more about the consequences of violent behavior rather than its definitions. Moreover, parental education is related to teenagers′ knowledge of the violent behavior so it is better that in various grades more comprehensive and suitable information regarding violent behaviors be presented.

After witnessing the deadly forces of volcanic eruptions as occurred from Mount Saint Helen in the U.S. and Mount Eyjofjallajokull in Iceland, which can cause so much death and destruction, it became obvious that, 'If we could reduce the forces involved we could reduce the catastrophic results significantly.' Typically, most of the volcanoes in Hawaii do not erupt as violently because they seem to be erupting and flowing on a somewhat regularly continuous basis or schedule. Our paper is suggesting a method, or many methods, by which the pressure buildup will be limited to substantially lower levels, than those which occur at present, by various procedures, before the actual eruption. We are suggesting that when we tame the highly destructive volcanoes' eruptions, we can reduce the effects which can ground more than a 100,000 flights; as occurred by Mount Eyjofjallajokull, back in 2010. It is critically important to be able to sense, measure, record and analyze the various conditions leading to the volcanic eruption.

To describe the intimate partner violence suffered by youth and to identify the descriptions that best classify it according to gender. A cross-sectional study was carried out among a sample of 3,087 adult Spanish students. The CUVINO questionnaire was used, which measures 8 forms of intimate partner violence and uses 3 descriptions to classify it (abuse, fear and entrapment). Logistic regressions were carried out to identify differences by gender and associations between the subtypes of intimate partner violence and descriptions of the violent experience. Nearly half of the sample (44.6%) had some situation of unperceived violence, mainly of "detachment" (30.0%) and "coercion" (25.1%). All subtypes of intimate partner violence were more frequently perpetrated by women. The largest difference by gender was found in "emotional punishment" (experienced by 20.9% of men vs. 7.6% of women) and "physical violence" (6.6% vs. 2.3%). A total of 28.7% felt trapped, 11.8% felt fear and 6.3% felt mistreated. Men more frequently described themselves as trapped, but less often as afraid or abused. The subtype of intimate partner violence most associated with the feeling of entrapment was coercion in both men (OR=3.8) and women (OR=5.7). Men and women face intimate partner violence while dating differently; resources are needed to address them specifically. The inclusion of routine questions about the sense of entrapment may contribute to the early detection of intimate partner violence. Subtle forms of violence, such as coercion, should be taken into account in awareness campaigns. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

Violent behaviors during sleep (VBS) are consequences of several sleep disorders but have received little attention in epidemiologic studies. This study aims to determine the prevalence of VBS in the general population and their comorbidity, familial links, course and treatment. Random stratified sample of 19,961 participants, 15 years and older, from the general population of Finland, Germany, Italy, Portugal, Spain and the United Kingdom were interviewed by telephone using the Sleep-EVAL Expert System. They answered a questionnaire on VBS, their consequences and treatment. Parasomnias and sleep and mental disorders were also evaluated. VBS was reported by 1.6% (95% confidence interval: 1.4-1.7%) of the sample. VBS was higher in subjects younger than 35 years. During VBS episodes, 78.7% of VBS subjects reported vivid dreams and 31.4% hurt themselves or someone else. Only 12.3% of them consulted a physician for these behaviors. In 72.8% of cases, VBS were associated with other parasomnias (highest odds of VBS for sleepwalking and sleep terrors). Family history of VBS, sleepwalking and sleep terrors was reported more frequently in VBS than in non-VBS subjects with odds of 9.3, 2.0 and 4.2, respectively. VBS are frequent in the general population and often associated with dream-enactment, sleepwalking and sleep terrors. High frequency of VBS, sleepwalking and sleep terrors in family of VBS subjects indicated that some families have a greater vulnerability to sleep disorders involving motor dyscontrol. Subjects who consulted a physician for these behaviors mostly received inappropriate or no support, indicating a lack of knowledge about VBS.
