Work on construction sites involves individuals with diverse character, temperament,age, physical strength, culture, religion and experience level. A good number of these individuals are also alleged to involve themselves in substance and alcohol abuse due to the physically demanding nature of their work. These could promote the prevalence of violence on construction sites which could in turn affect safety on construction sites. However, there is a lack of empirical insight into the effect of violent behaviour and unsafe behaviour on construction sites. This study therefore pioneers an empirical inquiry into the relationship between violent behaviour and unsafe behaviour on construction sites.

Seventeen violent behaviours and 15 unsafe behaviours were measured on 12 construction sites among 305 respondents using a structured questionnaire. A total of 207 valid questionnaire responses were collected from site workers. Partial least square–structural equation modelling (PLS-SEM) technique was used to examine the relationship between violent behaviour and unsafe behaviour.

The results indicate that there is a significant positive relationship between violent behaviour and unsafe behaviour on construction sites.

The findings from this study provide valuable insight into a less investigated dimension of the problem of construction site safety management. A focus on attitudinal issues such as how workers relate toward others and toward self should be an important consideration in safety improvement interventions on construction sites.

The present study sought to determine whether or not there is an association between contextual effects of violent socialization on violent youth behavior across different nations.

The data in this study derive from the International Dating Violence Study, a dataset of over 17,000 college students collected in 32 different nations. Variables consist of various scales from the Personal Relationship Profile that focuses on experiences and behaviors occurring prior to age 15 years, as well as national indicators of violence. Multilevel modeling analysis was used to analyze the data.

The results indicate two important findings. First, violent socialization significantly varies across different national contexts and this contextual effect accounts for a significant proportion of variation in youth violence. Second, violent socialization, both within individual families and as a contextual effect within different nations, is significantly associated with increases in violent youth behavior across the nations.

The International Dating Violence Study is a cross-sectional convenience sample of college students, which is not representative of specific nations nor college students. Further, the present study classifies nations as a “community” rather than explore microlevel communities within a nation. Future research should focus on examining variation of area specific norms for subsets of communities within nations with representative samples of a general population.

The present study appears to be one of the first published studies offering empirical evidence for international research on the theoretical argument of the contextual effects of violence within a nation, and begins to increase knowledge among criminologists of such contextual factors being associated with youth violent behavior across different nations.

The present study investigated the prevalence of mutual violence, violent attitudes and mental health symptoms among students in Botswana, Africa. The sample consisted of 562 university students from Botswana University in heterosexual relationships. Participants completed self‐report surveys that asked about violent attitudes, partner violence, controlling behaviours, and mental health symptoms. Results were that respondent and respondent partner's violent attitudes, partner violence and controlling behaviours were significantly related, revealing the mutuality of aggression within couples. Males reported higher violent attitudes but were just as likely as females to report controlling behaviours and physical partner perpetration. Multivariate analyses found that violent victimisation (physical and sexual), controlling behaviours and violent attitudes were significantly related to violent perpetration. Violent attitudes of the partner contributed to the respondent's violent perpetration of the partner. Respondents were likely to report more mental health symptoms if they experienced sexual violence and controlling behaviours by their intimate partners. Similarly, mental health symptoms of the respondents were associated with the partner's violent attitudes.

The purpose of this paper is to use data from the Longitudinal Study of Violent Criminal Behavior in the USA to examine case configurations of violent behavior using a biopsychosocial framework. Specifically, the theory posits that arguably all behavior is the result of specific combinations of biopsychological (individual) and sociocultural (environmental) characteristics that are interacting within the individual. With regard to criminal and violent behavior, the theoretical assumption is that this maladaptive behavior is the result of a negative interaction between the biopsychological and sociocultural factors.

The study design consists of secondary data analysis. A conjunctive analysis of case configurations was performed using data from the Longitudinal Survey of Violent Criminal Behavior to formally explore the tenets of Cortés and Gatti’s (1972) biopsychosocial theory.

The results suggest that there are main effects for ego strength, family problems, family incohesiveness and underachievement as they relate to offending. A possible six-way interaction was also identified within the case configurations that provides empirical support for Cortés and Gatti’s (1972) biopsychosocial theory of deviance.

The present study contributes to the existing biopsychosocial literature by providing insight on the contextual variability in pathways to violent offending. Specifically, the evidence provided indicates that Cortés and Gatti’s (1972) biopsychosocial theory of deviance can be extended to comparing violent and non-violent offenders. Implications for policy and practice are also discussed.

Inpatient violence can have a major impact in terms of traumatic experiences for victims and witnesses, an unsafe treatment climate, and high-financial costs. Therefore, the purpose of this paper is to gain more insight into patterns of violent behavior, so that adequate preventive measures can be taken.

Data on inpatient violence in a Dutch forensic psychiatric hospital between 2008 and 2014 were extracted from hospital files on 503 patients.

More than half of all the patients (n=276, 54.9 percent) displayed verbal aggression on at least one occasion, whereas 27.2 percent of all patients (n=137) exhibited one or more incidents of physical violence. Female patients were responsible for more physically violent episodes than male patients. Patients admitted with a civil court order exhibited more violent behavior than patients with a criminal court order. Violent patients with a civil commitment had a significantly longer length of stay than non-violent patients with a civil commitment. More violence was found to take place on the earlier days of the week.

This study points at important differences between groups of forensic inpatients in frequency and type of inpatient violent behavior and in temporal factors. Interventions aimed at reducing the number of violent incidents should take these differences into account. Further research is necessary to gain more insight into the background of inpatient violence.

There is an association between the diagnosis of a mental illness and violent behaviour. Individuals diagnosed with severe and enduring mental health difficulties who display violent behaviour have inferior treatment outcomes when compared with those who do not engage in violent behaviour. Violent behaviour within care settings impacts on general functioning, adherence to treatment plans, and inhibits wider recovery goals. The paper aims to discuss these issues.

This research studied 95 inpatients with a primary diagnosis of severe mental illness, with and without a history of violence, and compared how levels of global functioning and risk impacted on recovery. Patients were divided into two groups: those with and without a previous or current history of violence. The two groups were compared on measures of global functioning, symptomatology, and risk at baseline and 12-month follow up.

Both violent and non-violent groups showed increased global functioning over time, with no significant difference between the groups. Neither group showed significant reductions in risk over time. Patients in the violent group had significantly fewer prior and current symptoms of mental ill-health than non-violent individuals.

Despite evidence suggesting that historical or current violence leads to impaired outcomes amongst people with diagnoses of mental illness, the findings of this study suggest a history of violent behaviour was not a predictor of poor progress within inpatient settings.

Disconfirming previous hypotheses, the paper suggests that in itself, violent behaviour does not always significantly impair outcomes for individuals diagnosed with mental illnesses, and that many other variables contribute to meaningful recovery.

Whilst there are previous studies investigating outcomes for inpatients diagnosed with mental illness who have violent histories, there is a dearth of research comparing equivalent groups in the same facility over the same time period. This study directly compared inpatients with or without a history of violence in the same psychiatric rehabilitation settings.

Purpose – Description of the effects of the revolution in neuroscience and other areas of biology that can help to explain the roots of some portion of violent crime. The chapter reconsiders the role of brain chemistry in social behavior and violent behavior. To illustrate the interdisciplinary complexities entailed when linking brain chemistry to policy decisions concerning violent crime, this analysis has four main stages: first, why might SiFs (H2SiF6 and Na2SiF6, jointly called “silicofluorides” or SiFs) be dangerous? Second, what biochemical effects of SiF could have toxic consequences for humans? Third, on this basis a research hypothesis predicts children in communities using SiF should have increased uptake of lead from environmental sources and higher rates of behavioral dysfunctions known to be caused by lead neurotoxicity.

Design/methodology/approach – To illustrate the implications of the new issues involved, this chapter focuses on a public policy that inadvertently seems to increase rates of violent crime. Since violent behavior is one of the effects of lead neurotoxicity, the hypothesis is tested using multiple sources of data including rates of violent crime studied using a variety of multivariate statistical techniques (including analysis of variance, multiple regression, and stepwise regression).

Findings – Various data sources point to greater violence among individuals with greater exposure to SiFs.

Originality/value – Testing hypotheses linking neurotoxins to violent behavior reveals the generally unsuspected value of analyzing human social behavior and public policy from the perspective of evolutionary psychology.

Official criminal justice statistics (e.g. arrest rates) underestimate the frequency of crime because not all crime gets reported to authorities, a phenomenon known as the “dark figure of crime.” The present study aims to examine the dark figure of violence committed by discharged psychiatric patients.

Multiple reporting modalities permitted a direct comparison between patients whose violence was officially detected to those whose violence was self-reported but not officially detected, along with differences in the nature of violent acts.

Only 5% of violent individuals were officially detected, 26% of violent individuals were both officially detected and self-reported their violent behavior, while 68% of violent individuals self-reported their violent behavior and were not officially detected. The type of violent acts did not vary as a function of whether they were officially detected or self-reported. However, differences were observed for the location of violence, the relationship to the victim and whether an injury resulted. Older individuals, those with prior arrests and those with higher psychopathy scores are some of the factors associated with an increased likelihood of officially detected violence.

The data were collected from three sites in the USA. Generalizing the specific findings to other locations and countries ought to be done cautiously.

Studies ought to include multiple methods to measure violence. Self-report seems to be especially important to the extent one is concerned with measuring actual violence rather than violence that gets detected by legal authorities.

This study highlights an important limitation of relying exclusively on official criminal justice statistics when studying violence or recidivism in the community.

The purpose of this paper is to develop a theory of preventive health management for high-risk employees, who are the 1-3 percent with a propensity to become dangerous.

The paper reviews the literature and design a prevention model for high-risk employees that relies on primary, secondary, and tertiary surveillance indicators as well as prevention methods. The behaviors of these employees are often not accidental, even if not always intentional.

Primary prevention through organizational socialization and supervision can reduce emergence of high-risk employees. Early identification through secondary surveillance then prevention of incivility and deviance can deter escalation to violent behavior. When high-risk employees become dangerous and violent, tertiary prevention calls for containment, caregiving, forgiveness, and resilience.

The paper suggests that HR professionals can advance health, well-being, and performance while averting danger and violence by identifying and managing high-risk employees, anticipating their needs, and providing supportive resources and advising.

The paper applies public health prevention to deviant and violent employees.

Purpose – The consumption of violent media contents has been discussed as a risk factor for school shootings repeatedly. The results of research on U.S.-American offenders support this notion. However, to date only little is known about the extent to which these findings may be transferred and generalized to perpetrators from other countries.

Method – We analyzed the case files on seven school shootings perpetrated in Germany between 1999 and 2006.

Findings – In five cases, detailed qualitative content analyses revealed a marked interest in media violence during the years prior to the offense. In some cases, the media consumption slowly replaced other leisure activities, focussed on topics related to the offenses as killing sprees or former school shootings, and was partly described as being addictive. One offender even utilized the media for his own purposes in order to present himself postmortem. However, two perpetrators did not show any peculiar interest in media violence.

Practical and social implications – Violent media consumption is no necessary condition for school shootings, but seems to promote the development toward an offense under certain circumstances. Therefore, intensive media consumption, especially if thematically related to an offense, should be taken seriously and considered in prevention and intervention efforts.

Originality/value of chapter – The findings add to the literature on risk factors for school shootings with regard to violent media consumption. The subject is analyzed in detail in a sample of German offenders, thereby widening the scope of analyzed school shootings.
