    Full Text Available problem of the emergence of aggressive behavior is seen through the analysis of the relationship of proagressive and inhibiting aggression personality structures. The study involved 54 men serving sentences for criminal offenses, of which 24 were accused for violent offenses and 30 - for offenses without resorting to violence. We used questionnaires to study the proagressive and deterring aggression personality structures. Statistical analysis was performed to reveal significant differences between groups and to determine correlations. On this basis, the correlations were interpreted with the help of not only quantitative but also qualitative analysis. The results showed no significant differences in the level of expression of aggression and aggression inhibitors between treatment groups, but we identified qualitative differences in the structural analysis of data from individual psychological characteristics that are expected to distinguish aggressive offenders from the perpetrators without violence.

    Teen dating violence (TDV) is a serious form of youth violence that youth fairly commonly experience. Although youth extensively use computer-mediated communication (CMC), the epidemiology of CMC-based TDV is largely unknown. This study examined how perpetration of psychological TDV using CMC compares and relates to perpetration using longer-standing modes of communication (LSMC; e.g., face-to-face). Data from the national Growing up with Media study involving adolescents aged 14-19 collected from October 2010 to February 2011 and analyzed May 2012 are reported. Analyses focused on adolescents with a history of dating (n=615). Forty-six percent of youth daters had perpetrated psychological TDV. Of those who perpetrated in the past 12 months, 58% used only LSMC, 17% used only CMC, and 24% used both. Use of both CMC and LSMC was more likely among perpetrators who used CMC than among perpetrators who used LSMC. In addition, communication mode and type of psychological TDV behavior were separately related to frequency of perpetration. Finally, history of sexual intercourse was the only characteristic that discriminated between youth who perpetrated using different communication modes. Results suggest that perpetration of psychological TDV using CMC is prevalent and is an extension of perpetration using LSMC. Prevention should focus on preventing perpetration of LSMC-based TDV as doing so would prevent LSMC as well as CMC-based TDV.

    Contextual factors, such as exposure to stressors, may be antecedents to IPV perpetration. These contextual factors may be amenable to modification through intervention and prevention. However, few studies have examined specific contextual factors. To begin to address this gap, we examined the associations between financial stressors and three types of physical IPV perpetration. This analysis used data from Wave IV of The National Longitudinal Study of Adolescent to Adult Health. We used logistic regression to examine the associations of financial stressors and each type of IPV (minor, severe, causing injury), and multinomial logit regression to examine the associations of financial stressors and patterns of co-occurring types of IPV perpetration (only minor; only severe; minor and severe; minor, severe, and causing injury; compared with no perpetration). Fewer men perpetrated threats/minor physical IPV (6.7 %) or severe physical IPV (3.4 %) compared with women (11.4 % and 8.8 %, respectively). However, among physical IPV perpetrators, a higher percentage of men (32.0 %) than women (21.0 %) reported their partner was injured as a result of the IPV. In logistic regression models of each type of IPV perpetration, both the number of stressors experienced and several types of financial stressors were associated with perpetrating each type of IPV. Utilities nonpayment, housing nonpayment, food insecurity, and no phone service were associated with increased odds of perpetrating each form of IPV in adjusted analysis. Eviction was associated with perpetrating severe physical IPV but not threats/minor IPV or IPV causing injury. In multinomial logit regression comparing patterns of IPV perpetration to perpetrating no physical IPV, the relationships of financial stressors were less consistent. Food insecurity was associated with perpetrating only minor physical IPV. Comparatively, overall number of financial stressors and four types of financial stressors (utilities

    Full Text Available The present study was conducted on 78 cases in the Department of Medicine at G.S.V.M Medical College, Kanpur who reported with various gastrointestinal symptoms such as dyspepsia, heartburns, nausea, vomiting and loss of appetite. They all were advised for biopsy by the physician. Patients treated with antibiotics, bismuth or proton pump inhibitors within 4 weeks preceding the study were excluded. Invasive tests using mucosal biopsies including histology and rapid urease test (RUT were used to establish the gold standard in order to evaluate the accuracy of Immunocard STAT HpSA. Sensitivity, Specificity, Positive Predictive Value and Negative Predictive Value of Immunocard STAT HpSA as compared to gold standard were 95.5%, 81.8%, 96.9% and 75.0% respectively. It is thus concluded that the Immunocard STAT HpSA test has a diagnostic value comparable to the gold standard in detecting H Pylori. The sensitivity and specificity of the test is fair enough to be used as a test for screening purpose and also for diagnosis and treatment of H.Pylori infection in clinical practice

    Sexual intimate partner violence (IPV) is a public health problem worldwide. Research regarding beliefs about perpetrating sexual IPV is, however, limited. This study investigated attitudes, social influence, and self-efficacy beliefs and intentions toward perpetrating sexual IPV among Grade 8 adolescents ( M age = 13.73, SD = 1.04) in the Western Cape Province of South Africa. The study sample was taken from the baseline data of the Promoting sexual and reproductive health among adolescents in Southern and Eastern Africa (PREPARE) study, a cluster-randomized controlled trial. Young adolescents ( N = 2,199), from 42 randomly selected high schools, participated in the study and answered a paper-and-pencil questionnaire. Multivariate ANOVA were conducted to assess differences in beliefs and intention toward perpetrating sexual IPV between boys and girls, and between perpetrators and nonperpetrators. Results showed that boys were more frequently perpetrators (11.3% vs. 3.2%) and victims (13.6% vs. 6.4%) of sexual IPV than girls. Boys' attitudes toward perpetrating sexual IPV were more supportive than girls'. Boys perceived their social network to be more likely to think that putting pressure on a boyfriend or girlfriend to have sex is okay, and boys had a lower self-efficacy to refrain from pressuring a boyfriend or girlfriend to have sex compared with girls. Both boys and girls, who have perpetrated sexual IPV, had more tolerant attitude, social influence, and self-efficacy beliefs toward sexual IPV perpetration, compared with nonperpetrators. Intention not to perpetrate sexual IPV did not differ between boys and girls, or between perpetrators and nonperpetrators. Our findings suggest that interventions should address attitude and social influence beliefs regarding sexual IPV perpetration. More attention should be given to sexual IPV perpetration among boys. Given that sexual IPV victimization and perpetration are significantly linked, prevention of sexual IPV

    A significant proportion of reports of domestic violence against women involve multiple perpetrators. Although the number of perpetrators has been consistently identified as a measure of abuse severity, only a minority of studies of domestic violence examine the role of multiple offenders. Data on multi-perpetrator domestic violence (MDV) is frequently removed from analysis in domestic violence studies, or multi-perpetrator incidents are treated as single-perpetrator incidents. However, the available research links MDV to negative mental and physical health outcomes, intimate partner homicide, homelessness among women, and severe mental illness and suicidality. This article reviews the available prevalence data on MDV and draws together research on the contexts in which MDV takes place. It highlights two groups that are particularly vulnerable to MDV: (1) girls and women partnered to members of gangs and organized crime groups and (2) girls and women in some ethnic minority communities. While discussions of honor in relation to domestic violence are often racialized in Western media, this article highlights the cross-cultural role of masculine honor in collective violence against women in the working class and impoverished communities of majority cultures as well as in migrant and ethnic minority communities. It is clear that such complex forms of violence present a range of challenges for intervention and treatment and the article emphasizes the need for specialized and coordinated modes of investigation, support, and care.

    The current article reports on perpetrator characteristics gathered in the first large-scale prevalence study on interpersonal violence against children in sport in the Netherlands and Belgium. Using retrospective web survey design, 4043 adults answered questions on their experiences in youth sport. The study looks at the number of perpetrators as well as individual descriptive characteristics (sex, age, and role in the sport organization) of perpetrators of psychological, physical and sexual violence as reported retrospectively by victim-respondents. This information was then clustered to provide an overview of the most common perpetrator profiles. Results show that in all types of interpersonal violence in sport, perpetrators are predominantly male peer athletes who frequently operate together in (impromptu) groups. Several differences between the three types of interpersonal violence are highlighted. While incidents of physical violence perpetrated by coaches tend to be less severe compared to those by other perpetrators, acts of sexual violence committed by a coach are significantly more severe. The presented findings shed new light on perpetrators of interpersonal violence in sport, nuancing the predominant belief that the male coach is the main perpetrator while providing nuanced information that can be utilized to improve prevention and child protection measures and other safeguarding initiatives in sport.

    2010-01-01

    Background Over half a million U.S. women and more than 100,000 men are treated for injuries from intimate partner violence (IPV) annually, making IPV perpetration a major public health problem. However, little is known about causes of perpetration across the life course. Purpose This paper examines the role of “stress sensitization,” whereby adult stressors increase risk for IPV perpetration most strongly in people with a history of childhood adversity. Methods The study investigated a possible interaction effect between adulthood stressors and childhood adversities in risk of IPV perpetration, specifically, whether the difference in risk of IPV perpetration associated with past-year stressors varied by history of exposure to childhood adversity. Analyses were conducted in 2010 using de-identified data from 34,653 U.S. adults from the 2004–2005 follow-up wave of the National Epidemiologic Survey on Alcohol and Related Conditions. Results There was a significant stress sensitization effect. For men with high-level childhood adversity, past-year stressors were associated with an 8.8% increased risk of perpetrating compared to a 2.3% increased risk among men with low-level adversity. Women with high-level childhood adversity had a 14.3% increased risk compared with a 2.5% increased risk in the low-level adversity group. Conclusions Individuals with recent stressors and histories of childhood adversity are at particularly elevated risk of IPV perpetration; therefore, prevention efforts should target this population. Treatment programs for IPV perpetrators, which have not been effective in reducing risk of perpetrating, may benefit from further investigating the role of stress and stress reactivity in perpetration.

    Although family violence perpetrated by juveniles has been acknowledged as a potentially serious form of violence for over 30years, scientific studies have been limited to examining the incidence and form of home violence. The present study examined the prevalence of family aggression as perpetrated by youths; we examined groups drawn from clinic-referred and forensic samples. Two audits of case files were conducted to systematically document aggression perpetrated by referred youths toward their family members. The purpose of the first audit was fourfold: i) to identify the incidence of the perpetration of family aggression among clinical and forensic samples; ii) to identify whether there were any reports of weapon use during aggressive episodes; iii) to identify the target of family aggression (parents or siblings); and iv) to identify the form of aggression perpetrated (verbal or physical). The second audit aimed to replicate the findings and to show that the results were not due to differences in multiple deprivation indices, clinical diagnosis of disruptive behavior disorders, and placement into alternative care. A sampling strategy was designed to audit the case notes of 25 recent forensic Child and Adolescent Mental Health Service (CAMHS) cases and 25 demographically similar clinic-referred CAMHS cases in the first audit; and 35 forensic cases and 35 demographically similar clinic-referred CAMHS cases in the second audit. Using ordinal chi-square, the forensic sample (audit 1=64%; audit 2=82.9%) had greater instances of family violence than the clinical sample (audit 1=32%; audit 2=28.6%). They were more likely to use a weapon (audit 1=69%; audit 2=65.5%) compared to the clinical sample (audit 1 and 2=0%). Examining only the aggressive groups, there was more perpetration of aggression toward parents (audit 1, forensic=92%, clinical=75%; audit 2, forensic=55.17%, clinical=40%) than toward siblings (audit 1, forensic=43%, clinical=50%; audit 2, forensic=27

    This study sought to extend the confluence model of sexual assault perpetration by examining attachment insecurity and depression as additional predictors of sexual aggression. Male college students (N = 193) completed an online questionnaire assessing confluence model constructs in addition to attachment and history of depression. Overall, the model fit the data well, χ(2)(11, 193) = 19.43, p = ns; root mean square error of approximation = .063; comparative fit index = .94. Attachment and depression demonstrated both direct and indirect relationships with perpetration severity. The results contribute to elucidating the process by which certain men become susceptible to perpetrating sexual assault. Implications are discussed. © The Author(s) 2014.

    Relational aggression refers to harming others through damaging or manipulating peer relationships. In a cohort of students surveyed annually from middle to high school, this study identified groups of adolescents who followed distinct trajectories of perpetration and of victimization of relational aggression, compared the proportion of boys and girls in each trajectory, and examined the overlap between perpetration and victimization trajectories. The sample consisted of 620 randomly selected sixth graders. Students completed yearly surveys from Grade 6-12. We used group-based trajectory modeling to identify the trajectories. Adolescents followed three developmental trajectories of perpetration and three similar trajectories of victimization: Low (lowest aggression), Moderate, and High Declining (high in middle school, with a steep decline in high school). All trajectories declined from Grade 6-12. The largest groups were the Low perpetration (55%) and Low victimization (48%). Relational aggression trajectories differed by gender: more boys reported perpetration, and more girls reported victimization. For perpetration, slightly more boys than girls were classified in the two trajectories of higher aggression. For victimization, significantly fewer girls than boys were classified in the Low trajectory, and significantly more girls than boys were classified in the Moderate trajectory. There was substantial overlap of the perpetration and victimization trajectories. These findings highlight the importance of implementing programs to reduce relational aggression for boys and for girls. © 2014 Wiley Periodicals, Inc.

    2014-01-01

    Objective: To examine the extent to which abused and neglected children perpetrate three different types of violence within and outside the home: criminal, child abuse, and intimate partner violence and determine whether childhood maltreatment leads to an increased risk for poly-violence perpetration. Method: Using data from a prospective cohort design study, children (ages 0-11) with documented histories of physical and sexual abuse and/or neglect (n = 676) were matched with children without such histories (n = 520) and assessed in young adulthood (average age 29). Official criminal records in conjunction with self-report data were used to assess violent outcomes. Results: Compared to the control group, individuals with histories of child abuse and/or neglect were significantly more likely to be poly-violence perpetrators, perpetrating violence in all three domains (relative risk = 1.26). All forms of childhood maltreatment (physical and sexual abuse and neglect) significantly predicted poly-violence perpetration. Conclusions: These findings expand the cycle of violence literature by combining the distinct literatures on criminal violence, child abuse, and partner violence to call attention to the phenomenon of poly-violence perpetration by maltreated children. Future research should examine the characteristics of maltreated children who become poly-violence perpetrators and mechanisms that lead to these outcomes. PMID:26191459

    We examined perpetration of bullying among youths in vulnerable groups relative to youths in peer groups not categorized as vulnerable. Data were collected in 2013 from a large school-based survey of adolescents conducted in Minnesota (n = 122,180). We used the χ(2) test and logistic regression to compare measures of perpetration of physical and relational bullying, as well as experiences of victimization and perpetration (or both), across categories of sexual orientation, weight status, and disability status. Rates of physical and relational bullying perpetration were significantly higher among youths in vulnerable groups than among those not in vulnerable groups. With respect to context of victimization experiences, young men and women from vulnerable groups were overrepresented in the group comprising both perpetrators and victims. For example, odds of being both a perpetrator and a victim were 1.41 to 3.22 times higher among gay, lesbian, and bisexual youths than among heterosexual youths. Vulnerable youths, who are prone to peer harassment, may also act as perpetrators of bullying. Prevention strategies should address the particular needs of these populations; targeted programming may be appropriate.

    To assess the relationship between bullying peers as a child and adult intimate partner violence perpetration in a clinic-based sample of adult men. School bullying perpetration and intimate partner violence perpetration are both thought to stem from desire for power and control over others. A cross-sectional survey was conducted between January 2005 and December 2006. Three urban community health centers in Boston, Massachusetts. Men aged 18 to 35 years (n = 1491) seeking services at participating community health centers. School bullying perpetration. Past-year physical or sexual violence perpetration against a female partner (intimate-partner violence [IPV]). Two-fifths of men reported perpetrating school bullying as a child (n = 610; 40.9%). Men who rarely bullied in school were 1.53 times more likely to perpetrate past-year IPV than men who did not bully (95% confidence interval [CI], 1.02-2.29); this risk was elevated to 3.82 times more likely to perpetrate any past-year IPV for those men who bullied peers frequently (95% CI, 2.55-5.73). The present study indicates that bullying peers in school as a child, especially frequent bullying perpetration, is associated with increased risk for men's perpetration of IPV as an adult. The effect remains strong after controlling for common prior risk factors for both bullying and IPV perpetration. Future research is needed to discern the mechanisms and underlying root causes of abusive behavior, such as power and control, as a means to prevent violence perpetration across settings and life stages.

    Despite extensive evidence of heterogeneity in intimate partner violence (IPV) perpetrator profiles, there has been little research into neuropsychological deficits that might help us understand differences within this violent population. Moreover, studies on this topic have not paid much attention to the role of alcohol abuse in neuropsychological domains of IPV perpetrators. Hence, the current study was designed to examine neuropsychological differences among individuals who have committed domestic violence with high (n = 28, HA) and low (n = 35, LA) levels of alcohol consumption, and non-violent individuals (n = 37) to establish differential neuropsychological profiles. An exhaustive neuropsychological assessment battery was employed which combined the computer-based Cambridge Neuropsychological Test Automated Battery with pencil-and-paper measures. Compared to controls, HA IPV perpetrators had slower processing speed and significantly more impairments in attentional set-shifting or switch attention, working and long-term memory, cognitive flexibility, planning, decision-making, emotion decoding skills, and perspective taking. Furthermore, there were differences between IPV perpetrator subgroups in attentional set-shifting or switch attention and cognitive empathy, with HA IPV perpetrators displaying more severe impairments in both cognitive domains than LA IPV perpetrators. Finally, the LA IPV perpetrators had significantly more impairments in working and long-term memory, executive functioning, and emotion decoding skills than controls, but they did not differ in processing speed, attentional set-shifting or switch attention, decision making, or perspective taking. Thus, the current findings suggest that IPV perpetrators with neuropsychological difficulties, especially those who are heavy drinkers, may have the greatest need for cognitive interventions. These cognitive deficits could be employed as targets for developing specific cognitive rehabilitation

    The diagnosis of abusive head trauma (AHT) remains a significant public health problem with limited prevention success. Providing protection from further harm is often challenged by the difficulty in identifying the alleged perpetrator (AP) responsible for this pediatric trauma. The objective of this study was to evaluate demographic and clinical characteristics of children with AHT and the relationship between APs and their victims in a large, multi-site sample. Understanding the AHT risks from various caregivers may help to inform current prevention strategies. A retrospective review of all cases of AHT diagnosed by child protection teams (CPT) from 1/1/04 to 6/30/09 at four children's hospitals was conducted. Clinical characteristics of children with AHT injured by non-parental perpetrators (NPP) were compared to parental perpetrators (PP). There were 459 children with AHT; 313 (68%) had an identified AP. The majority of the 313 children were <1 year of age (76%), Caucasian (63%), male (58%), receiving public assistance (80%), and presented without a history of trauma (62%); mortality was 19%. Overall, APs were: father (53%), parent partner (22%), mother (8%), babysitter (8%), other adult caregiver (5%); NPP accounted for 39% of APs. NPPs were more likely to cause AHT in children ≥ 1 year (77% vs. 23%, p<0.001) compared to PP. Independent associations to NPP included: older child, absence of a history of trauma, retinal hemorrhages, and male perpetrator gender. While fathers were the most common AP in AHT victims, there is a significant association for increased risk of AHT by NPPs in the older child, who presents with retinal hemorrhages, in the hands of a male AP. Further enhancement of current prevention strategies to address AHT risks of non-parental adults who provide care to children, especially in the post-infancy age seems warranted.

    Despite a limited empirical literature, parental mental illness is often cited as a major risk factor for violence against children. However, mental illness that is adequately treated would not be expected to lead to increased violence risk. This study compared incidents of violence toward children perpetrated by parents who were newly discharged from inpatient psychiatric treatment with violence perpetrated by other parents in the same communities to determine whether parents with treated mental illness had an elevated risk of child abuse perpetration. A secondary analysis of data from the MacArthur Violence Risk Assessment Study was conducted. Violence toward children reported by parents and by collateral informants at the initial ten-week follow-up interview was analyzed for two groups: study participants discharged from inpatient psychiatric facilities and parents in the community matched by neighborhood. Of the 416 parents in the participant group, 20 (5%) committed violence toward a child in the ten weeks after discharge, compared with 41 (14%) of the 299 parents in the comparison group. In the participant group, diagnostic categories of parents who committed violence toward a child were as follows: serious mental illness only (8% of whom were violent), substance use disorder only (3%), both serious mental illness and substance use disorder (4%), and another issue (7%). This study found that parents with treated serious mental illness were not at higher risk than other parents in their community of perpetrating violence toward children. Parents who were admitted to an acute psychiatric facility and treated appeared to be at lower risk of being violent toward children than other parents in their community.

    This study was undertaken to examine whether alleged child sexual abuse perpetrators are handled differently by the courts than other alleged felony perpetrators. Comparisons were made from the time of prosecutorial case acceptance through prosecution to sentencing, with emphasis on judicial and prosecutorial decision-making and plea-bargaining. Data were retrospectively abstracted on the entire defendant population of cases of sexual abuse of children and adolescents (ages 2-17) over a 5-year period. Using a case-flow analysis, comparisons were made between a child sexual abuse cohort and a cohort of matched felony cases from a single jurisdiction. Three important findings emerged. First, compared to other felons, abuse perpetrators were employed, had been married, were mostly European American, and were older than 30 years of age. Second, in the abuse cohort, as many as 14% had a previous sexual or violent record compared to 2% in the comparison group. Third, similar percentages of perpetrators in both groups were released on their own recognizance, had the charges against them dropped, and were found guilty. As well, no differences between groups were found in the proportion of individuals sentenced to jail, probation, counseling, or work release. Although the treatment of perpetrators of child sexual abuse was similar to the treatment of perpetrators of other felonies, the profile of the child abuse perpetrator was quite different. Knowledge about this profile may impact prosecution or treatment and recidivism rates, to the extent that recidivism is related to characteristics of the abuse perpetrator.

    Sexual violence (SV) perpetration on college campuses is a serious and prevalent public health issue in the U.S. In response, incoming male freshmen are mandated to receive SV prevention programming. To provide a more effective response, however, we need to understand the SV behaviors of male freshmen before they arrive on campus and the associated factors that contribute to risk and that afford protection, areas that have received limited attention. Male freshmen (N = 1,133) across 30 selected 4-year colleges and universities throughout the state of Georgia were recruited for a longitudinal study on SV perpetration. Levels of precollege SV as well as a range of covariates were assessed at baseline. Self-reported SV perpetrators were compared with nonperpetrators on demographic and hypothesized covariates deemed either risk or protective; then risk and protective models were analyzed using binary logistic regression. Weighted analyses revealed that 19.3% self-reported perpetrating SV before college. Before starting college, young men who reported more sexual media consumption, heavy episodic drinking, hypermasculine beliefs, and peers who endorsed SV were more likely to have a history of SV perpetration at college matriculation. Alternatively, men with more knowledge of effective sexual consent and stronger family functioning were less likely to arrive to college with an SV perpetration history. A significant proportion of incoming male freshmen have perpetrated SV previously. Colleges and universities need to assess incoming freshmen for risk behaviors and negative beliefs and to offer both primary and secondary preventions to more effectively reduce further perpetration.

    This study aims to describe child homicide perpetrators and estimate their global and regional proportion to inform prevention strategies to reduce child homicide mortality worldwide. A systematic review of 9431 studies derived from 18 databases led to the inclusion of 126 studies after double screening. All included studies reported a number or proportion of child homicides perpetrators. 169 countries and homicide experts were surveyed in addition. The median proportion for each perpetrator category was calculated by region and overall and by age groups and sex. Data were obtained for 44 countries. Overall, parents committed 56.5% (IQR 23.7-69.6) of child homicides, 58.4% (0.0-66.7) of female and 46.8% (14.1-63.8) of male child homicides. Acquaintances committed 12.6% (5.9-31.3) of child homicides. Almost a tenth (9.2% (IQR 0.0-21.9) of child homicides had missing information on the perpetrator. The largest proportion of parental homicides of children was found in high-income countries (64.2%; 44.7-71.8) and East Asia and Pacific Region (61.7%; 46.7-78.6). Parents committed the majority (77.8% (61.5-100.0)) of homicides of children under the age of 1 year. For adolescents, acquaintances were the main group of homicide perpetrators (36.9%, 6.6-51.8). There is a notable lack of studies from low-income and middle-income countries and children above the age of 1 year. Children face the highest risk of homicide by parents and someone they know. Increased investment into the compilation of routine data on child homicide, and the perpetrators of this homicide is imperative for understanding and ultimately reducing child homicide mortality worldwide.

    Previous research in offline environments suggests that there may be an overlap in bullying and sexual harassment perpetration and victimization; however to what extent this may be true for perpetration and victimization of Internet harassment and unwanted sexual solicitation is unknown. The Growing Up with Media survey is a national cross-sectional online survey of 1,588 youth, 10-15 years old, who have used the Internet at least once in the last 6 months. Cluster analysis was conducted with four scales: Internet harassment perpetration, Internet harassment victimization, unwanted sexual solicitation perpetration, and unwanted sexual solicitation victimization. A four-cluster solution was identified: youth with little to no involvement (n = 1326; 81.7%); perpetrator-victims of Internet harassment (n = 205; 14.3%); victims of both Internet harassment and unwanted sexual solicitation (n = 45; 3.1%); and perpetrator-victims of Internet harassment and unwanted sexual solicitation (n = 12; .9%). Involvement in Internet harassment and unwanted sexual solicitation was associated with concurrent reports of psychosocial problems including substance use; involvement in offline victimization and perpetration of relational, physical, and sexual aggression; delinquent peers; a propensity to respond to stimuli with anger; poor emotional bond with caregivers; and poor caregiver monitoring as compared with youth with little to no involvement. This was especially true for perpetrator-victims of Internet harassment and unwanted sexual solicitation. Findings were replicated using a frequency-based definition of involvement, suggesting that cluster analysis is useful in identifying subgroups of youth and can be used to guide frequency-based definitions, which are easier to implement across study samples. The majority of youth are not frequently involved in Internet harassment or unwanted sexual solicitation either as victims or as perpetrators. Among those who are, however

    Subtyping male perpetrators of intimate partner violence (IPV) based on their generality of violence could facilitate the difficult task of matching perpetrator subtype with efficient risk management strategies. As such, the aim of the present study was to compare antisocial and family-only male perpetrators of interpersonal violence in terms of (a) demographic and legal characteristics, (b) risk factors for violence, and (c) assessed risk and the importance of specific risk factors for violence. A quantitative design was used in this retrospective register study on data obtained from the Swedish police. Risk assessments performed with the Swedish version of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) and police registers were used. A sample of 657 male alleged IPV perpetrators were classified asantisocial(n= 341) orfamily-only(n= 316) based on their generality of violence. The results showed that the antisocial perpetrators were significantly younger, as well as more psychologically abusive. Antisocial perpetrators also had significantly more present risk factors for IPV, and were assessed with a significantly higher risk for acute and severe or deadly IPV, compared with the family-only perpetrators. The subtypes also evidenced unique risk factors with a significant impact on elevated risk for acute and severe or deadly such violence. Key findings in the present study concerned the subtypes evidencing unique risk factors increasing the risk for acute and severe or deadly IPV. Major implications of this study include the findings of such unique "red flag" risk factors for each subtype. To prevent future IPV, it is vital for the risk assessor to be aware of these red flags when making decisions about risk, as well as risk management strategies. © The Author(s) 2016.

    We assess the association of men's exposure to violence in childhood-witnessing physical violence against one's mother and being hit or beaten by a parent or adult relative-with their attitudes about intimate partner violence (IPV) against women. We explore whether men's perpetration of IPV mediates this relationship and whether men's attitudes about IPV mediate any relationship of exposure to violence in childhood with perpetration of IPV. Five hundred twenty-two married men 18-51 years in Vietnam were interviewed. Multivariate regressions for ordinal and binary responses were estimated to assess these relationships. Compared with men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of reporting more reasons to hit a wife (aOR, 1.43; 95% CI, 1.03-2.00 and aOR, 1.66; 95% CI, 1.05-2.64, respectively). Men's lifetime perpetration of IPV accounted fully for these associations. Compared with men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of ever perpetrating IPV (aOR, 3.28; 95% CI, 2.15-4.99 and aOR, 4.56; 95% CI, 2.90-7.17, respectively). Attitudes about IPV modestly attenuated these associations. Addressing violence in childhood is needed to change men's risk of perpetrating IPV and greater subsequent justification of it.

    Abstract Introduction and Aims Controlling behaviours are highly prevalent forms of non‐physical intimate partner violence (IPV). The prevalence of perpetrating controlling behaviours and technology‐facilitated abuse (TFA) was compared by men receiving substance use treatment in England (n = 223) and Brazil (n = 280). Factors associated with perpetrating these behaviours towards their current/most recent partner and their association with other types of IPV were explored. Design and Methods Secondary analysis from two cross‐sectional studies was performed. Data on socio‐demographic characteristics, infidelity, IPV perpetration and victimisation, adverse childhood experiences (ACE), attitudes towards gender relations and roles, substance use, depressive symptoms and anger expression were collected. Results Sixty‐four percent (143/223) and 33% (73/223) of participants in England and 65% (184/280) and 20% (57/280) in Brazil reported controlling behaviours and TFA, respectively, during their current/most recent relationship. Excluding IPV victimisation from the multivariate models; perpetrating controlling behaviours was associated with a higher number of ACE, higher anger expression (England) and severe physical IPV perpetration (Brazil), and perpetrating TFA was associated with younger age. Including both IPV victimisation and perpetration in the multivariate models; perpetrating controlling behaviour was associated with experiencing a higher number of ACE, higher anger expression (England), emotional IPV victimisation (England) and experiencing controlling behaviour from a partner (England). The perpetration of TFA was associated with younger age and experiencing TFA from a partner. Conclusions Technological progress provides opportunities for perpetrators to control and abuse their partners. Controlling behaviours and TFA should be addressed to reduce IPV perpetration by males in substance use treatment. [Gilchrist G, Canfield M,Radcliffe P, d

    Intimate partner violence (IPV) perpetrators have been categorized into two groups based on their heart rate (HR) reactivity to stress following Gottman's studies. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II or reactive perpetrators present a hyper-reactivity in anticipation of stress. In this study, changes in HR, pre-ejection period (PEP), vagal ratio as well as psychological state variables (anxiety and anger) in response to stress were assessed, comparing a group of type II IPV perpetrators (based on violence reports and psychological assessment; n = 17; mean age = 37) with non-violent controls (n = 17; mean age = 35) using modified version of the Trier Social Stress Test. IPV perpetrators had higher HRs and lower vagal ratios than controls, particularly during the recovery period. Moreover, the former presented shorter PEPs than controls. There were no differences between groups in the magnitude of response of the HR, PEP or vagal ratio. High baseline anxiety and anger were associated with an HR increase during the preparation time in IPV perpetrators but not in controls. These findings indicate a different cardiovascular pattern of response to psychosocial stress in IPV perpetrators, especially during recovery. Thus, they contribute to understanding the biological functioning of violence sub-types, supporting the validity of cardiovascular measures as diagnostic indicators for IPV classification.

    Space density- and luminosity-functions for the photometric halo- and disc-populations in the test-field SA 54 of the Basle Halo Program have been derived on the basis of UBV observations of the same 1377 stars used already for the corresponding RGU investigation by Fenkart (1968). The statistical method for separating the photometrically defined populations and for attributing absolute magnitudes to their members developed, described and first applied to SA 51 in RGU by Becker (1965) has been adapted for use in the UBV system. The (U-B, B- V) diagrams for consecutive intervals in apparent V-magnitude of figures 2a to f contain, contrary to what was first expected in this system, substantial numbers of stars in the covered by this investigation for halo and disc are given in tables IIa and b, and plotted in figures 3 and 4, respectively. The corresponding luminosity-functions within the partial volume up to 1 kpc from the sun over the same overall MVinterval are given together with Glieses (1969) solar values for population I, in table III, and plotted in figure 5. The overall density-functions (3m ≦ MV ≦ 7m) for both populations can be and are compared with the corresponding ones (3m ≦ MG ≦ 8m) in RGU (last column in table II) in figures 6 and 7, for halo and disc, respectively. The coincidence of the density results between UBV and RGU is much better for both populations than the mean misidentification rate per system derived in section 5 would let us expect, suggesting a statistically fairly repartition of the misidentifications with respect to absolute magnitudes and distances.

    It is commonly assumed that male abuse is more damaging than female abuse, just as it previously has been assumed that physical abuse is more harmful than psychological abuse. We sought to examine gender assumptions given that they may cause people to overlook the harm that men experience with a psychologically abusive partner. The current experiment compared perceptions of male and female perpetrators of psychological abuse, and examined whether gendered perceptions were affected by sexist beliefs or participants' own sex. The experiment also explored the effect of the victim's response to a perpetrator's abuse. College participants ( N = 195) read a scenario depicting a hypothetical marital conflict that manipulated the sex of the perpetrator, the level of abuse (abuse or no abuse), and whether the victim did or did not respond with some aggression. In scenarios that featured abuse (relative to no-abuse conditions), a male perpetrator was consistently perceived more harshly than a female perpetrator. Participant sex and sexism did not moderate this gender-based perception. Varying the victim's response in the scenario affected perceptions more in the no-abuse condition than in the abuse condition. The findings are discussed in terms of robust gender assumptions and the difficulties in challenging such assumptions.

    The National Elder Mistreatment Study (NEMS) found that 5.2% of community older adults experienced financial abuse, and 4.6% experienced emotional mistreatment in the past year. Unfortunately, the majority of abuse was not reported to the authorities. This study investigated reasons for non-reporting. In all, 774 NEMS participants were surveyed 8 years later via telephone to assess past-year financial and emotional mistreatment, perpetrator status, and whether any of these episodes were reported to authorities. In total, 87.5% of financial abuse by family, friends, or acquaintances was not reported versus 33% of that perpetrated by strangers; for emotional mistreatment, 89.9% of that perpetrated by family, friends, and acquaintances was not reported, compared with 83.3% by strangers. Reasons for non-reporting of emotional abuse centered largely around with "not wanting publicity" and "not wanting to get the perpetrator in trouble," while no consistent reason emerged for failure to report stranger-perpetrated mistreatment.

    This study investigated bullying among siblings in both traditional and cyber forms, and the associations of gender, grade, peer bullying perpetration, trait anger, and moral disengagement. The participants were 455 children in Grades 5 to 12 (262 girls and 177 boys with 16 unknown gender) who had a sibling. As the number of siblings who only bullied by technology was low, these associations were not able to be calculated. However, the findings showed that the percentage of sibling traditional bullying perpetration (31.6%) was higher than peer bullying perpetration (9.8%). Sibling bullies reported engaging in complex behaviors of perpetration and victimization in both the physical and in cyber settings, although the number was small. Gender, trait anger, moral disengagement, and bullying peers at school (but not grade) were all significantly associated with sibling traditional bullying perpetration. The implications of the findings are discussed for bullying intervention and prevention programs to understand childhood bullying in diverse contexts. © The Author(s) 2014.

    Criminal acts are sometimes described using animal metaphors. What is the impact of a violent crime being described in an animalistic versus a non-animalistic way on the subsequent retribution toward the perpetrator? In two studies, we experimentally varied animalistic descriptions of a violent crime and examined its effect on the severity of the punishment for the act. In Study 1, we showed that compared to non-animalistic descriptions, animalistic descriptions resulted in significantly harsher punishment for the perpetrator. In Study 2, we replicated this effect and further demonstrated that this harsher sentencing is explained by an increase in perceived risk of recidivism. Our findings suggest that animalistic descriptions of crimes lead to more retaliation against the perpetrator by inducing the perception that he is likely to continue engaging in violence. © 2014 Wiley Periodicals, Inc.

    Alcohol intoxication has been associated with dating violence perpetration, defined here as psychological and/or physical violence occurring between young adult dating partners. However, little is known about how the individual variability in the level of alcohol intoxication would influence dating violence perpetration and how sex and self-regulation might influence this association. College-aged men and women (N = 146) from a large southwestern U.S. university completed background questionnaires, including the Brief Self-Control Scale, to assess self-regulation and then reported their dating violence perpetration and alcohol consumption using a 90-day Timeline Followback assessment. Their average estimated blood alcohol concentration (eBAC) and their daily deviation from this average were calculated for each of the 90 days to examine the between- and within-person effects of alcohol consumption, respectively. Results of a two-level generalized estimating equation suggest that increases in daily eBAC were associated with an increased likelihood of perpetrating dating violence; however, this association was stronger for those who had a low average eBAC compared with those who had a high average eBAC. For those who had a low average eBAC, higher self-regulation was associated with a lower probability of perpetrating dating violence, whereas among those with a high average eBAC, self-regulation was not associated with dating violence perpetration. Sex did not moderate the association between eBAC and dating violence perpetration. Findings highlight the importance of self-regulation in dating violence perpetration-particularly for those with low average eBACs-and the need for varied intervention strategies, depending on one's typical drinking pattern.

    Cell-phone conversation is ubiquitous within public spaces. The current study investigates whether ignored cell-phone conversation impairs eyewitness memory for a perpetrator. Participants viewed a video of a staged crime in the presence of 1 side of a comprehensible cell-phone conversation (meaningful halfalogue), 2 sides of a comprehensible cell-phone conversation (meaningful dialogue), 1 side of an incomprehensible cell-phone conversation (meaningless halfalogue), or quiet. Between 24 and 28 hr later, participants freely described the perpetrator's face, constructed a single composite image of the perpetrator from memory, and attempted to identify the perpetrator from a sequential lineup. Further, participants rated the likeness of the composites to the perpetrator. Face recall and lineup identification were impaired when participants witnessed the staged crime in the presence of a meaningful halfalogue compared to a meaningless halfalogue, meaningful dialogue, or quiet. Moreover, likeness ratings showed that the composites constructed after ignoring the meaningful halfalogue resembled the perpetrator less than did those constructed after experiencing quiet or ignoring a meaningless halfalogue or a meaningful dialogue. The unpredictability of the meaningful content of the halfalogue, rather than its acoustic unexpectedness, produces distraction. The results are novel in that they suggest that an everyday distraction, even when presented in a different modality to target information, can impair the long-term memory of an eyewitness.

    Although dating violence is prevalent among college students, little is known about how both attachment style and participation in risky behaviors contribute to this pattern of violence. To address this literature gap, we examine the role of poor parenting, child abuse, attachment style, and risky sexual and drug use behaviors on dating violence perpetration among 1,432 college students (51% female). Path analysis results revealed that females were more likely to report greater attachment anxiety but lower attachment avoidance compared with males. Correlates of attachment anxiety included child physical abuse, witnessing parental violence, and poorer maternal relationship quality whereas attachment avoidant behavior was linked to more physical abuse and poorer maternal relationship quality. Females were more likely to perpetrate dating violence as were those with greater attachment anxiety and lower attachment avoidance. Other correlates of dating violence perpetration included sexual and drug risk behaviors. Finally, distal factors (i.e., more child physical abuse and poorer maternal relationship quality) also were associated with dating violence perpetration. Study implications are also discussed.

    This study was conducted in Serbian companies on licensed engineers and in its first part included a total of 336 licensed engineers who voluntarily completed the questionnaires about their ethical orientation and attitudes toward corruption and in the second part 214 engineers who participated in the first survey, who voluntarily evaluated their company's business operations characteristics. This study has clearly shown that there is a direct significant influence of the engineer's ethical orientations and attitudes toward corruption on their evaluation of the characteristics of their respective companies regarding business operations. This research also clearly shows that only engineers with a strong deontological orientation, low ethical subjectivity, and strong readiness to fight corruption, low corruption acceptance and high awareness of corruption can successfully fight corruption, improve the business operations of their companies and make beneficial changes to society. Otherwise, they should be considered as corruption perpetrators, not just as its victims.

    Forensic psychiatric reports on 166 sexual homicide perpetrators in Germany were retrospectively analyzed for criminal risk factors. Follow-up information about release and reconvictions from federal criminal records was available for 139 offenders; 90 (64.7%) had been released. The estimated recidivism rate (Kaplan-Meier analyses) for 20 years at risk was 23.1% for sexual and 18.3% for nonsexual violent reoffences. Three men (3.3%) were reconvicted for attempted or completed homicide. Only young age at the time of sexual homicide resulted in higher sexual recidivism, whereas increased nonsexual violent recidivism was related to previous sexual and nonsexual delinquency, psychopathic symptoms, and higher scores in risk assessment instruments. Increased recidivism with any violent reoffence was associated with age-related factors: young age at first sexual offence, at homicide, and at release and duration of detention. The impacts of the results for risk assessment, relapse prevention, and supervision are discussed.

    2016-02-01

    The tendency to label all elder abuse perpetrators as the "bad guys" has diminished our ability to respond effectively. A review of the literature demonstrates that elder abuse perpetrators are in fact heterogeneous with important differences across types of abuse. A reformulation of perpetrator interventions away from a singular emphasis on prosecution to meaningful alternatives that utilize criminal justice and/or therapeutic approaches tailored to the needs of the case is needed. These interventions must incorporate the needs of both victims and perpetrators, take into consideration the type of abuse involved, acknowledge the variations in perpetrator culpability, and recognize the continuum of complexity among these cases. Without addressing these nuances, intervention and prevention efforts will be futile if not harmful. © The Author(s) 2014.

    To conduct a multilevel analysis of risk factors for physical violence perpetration by school staff against Ugandan students. Multilevel logistic regression analysis of cross-sectional survey data from 499 staff and 828 caregivers of students at 38 primary schools, collected in 2012 and 2014 during the Good Schools Study. Luwero District, Uganda. Past-week use of physical violence by school staff against students was measured using the International Society for the Prevention of Child Abuse and Neglect 'Child Abuse Screening Tool- Child International' and the WHO Multi-Country Study on Women's Health and Domestic Violence against Women. Of 499 staff, 215 (43%) reported perpetration of physical violence against students in the past week. Individual risk factors associated with physical violence perpetration included being a teacher versus another type of staff member (pviolence against non-students (pviolence (IPV) (pviolence perpetration compared with male staff who had not been a victim of IPV. No evidence was observed for school- or community-level risk factors. Physical violence perpetration from school staff is widespread, and interventions are needed to address this issue. Staff who have been victims of violence and who use violence against people other than students may benefit from additional interventions. Researchers should further investigate how school and community contexts influence staff's physical violence usage, given a lack of associations observed in this study. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    We examined correlations between gender, race, sexual identity, and technology use, and patterns of cyberbullying experiences and behaviors among middle-school students. We collected a probability sample of 1285 students alongside the 2012 Youth Risk Behavior Survey in Los Angeles Unified School District middle schools. We used logistic regressions to assess the correlates of being a cyberbully perpetrator, victim, and perpetrator-victim (i.e., bidirectional cyberbullying behavior). In this sample, 6.6% reported being a cyberbully victim, 5.0% reported being a perpetrator, and 4.3% reported being a perpetrator-victim. Cyberbullying behavior frequently occurred on Facebook or via text messaging. Cyberbully perpetrators, victims, and perpetrators-victims all were more likely to report using the Internet for at least 3 hours per day. Sexual-minority students and students who texted at least 50 times per day were more likely to report cyberbullying victimization. Girls were more likely to report being perpetrators-victims. Cyberbullying interventions should account for gender and sexual identity, as well as the possible benefits of educational interventions for intensive Internet users and frequent texters.

    Adults perpetrate the majority of animal abuse incidents yet clinicians are left with very little evidence base to advance/enhance their practice. The purpose of this systematic review is to synthesize and evaluate the current literature on adult-perpetrated animal abuse and to identify the etiological factors related to this type of offending. Twenty-three studies met the specific inclusion criteria but most importantly, they examined the characteristics of adult perpetrators of animal abuse. The findings from this review were demarcated by sample type: (1) Participants were the perpetrators of the animal abuse or held offense-supportive attitudes and (2) participants were victims of intimate partner violence reporting incidents of animal abuse perpetrated by their partner. From the perpetrator perspective, there were key developmental (i.e., maladaptive parenting strategies), behavioral (such as varied offending behaviors), and psychological (e.g., callousness, empathy deficits) factors highlighted in the literature. Finally, in the context of intimate partner violence, findings indicated that perpetrators abuse animals to control, coerce, intimidate, and/or manipulate their victims (this effect is moderated by the victims' emotional attachment to their pet). This review inherently underlines treatment targets that could achieve greater clinical gains, but we also conclude that more empirical and theoretical work is needed in order to set an agenda that prioritizes future research and effective practice.

    Intimate partner violence (IPV) perpetrators were categorized into 2 groups using Gottman et al.'s (1995) typology depending on their skin conductance (SC) reactivity to stress. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II perpetrators present a preparatory hyperreactivity to confront stress. Moreover, impulsivity traits and testosterone (T) levels may modulate SC responses to increase the risk of proneness to violence. In this study, SC response to stress was assessed by comparing IPV perpetrators with non-violent controls while performing a modified version of the Trier Social Stress Test (TSST). Subjects with a history of IPV demonstrated higher non-specific SC responses during the recovery period than the non-violent controls. Nonetheless, there were no differences between groups in the case of mean SC levels. Furthermore, impulsivity and baseline T levels were associated with higher SC level reactivity during a preparation period only in IPV perpetrators, with both relationships being mediated by anger expression. Our results confirm that the IPV perpetrators correspond physiologically to type II and support the validity of SC as a diagnostic indicator for IPV classification. Our findings contribute to the development of effective treatment and prevention programs that could benefit from the use of biological indicators for analyzing the risk of recidivism in IPV perpetrators. © 2013.

    This paper examines men's lifetime physical intimate partner violence (IPV) perpetration across eight low- and middle-income countries to better understand key risk factors that interventions can target in order to promote gender equality and reduce IPV. We use data from men (n = 7806) that were collected as part of the International Men and Gender Equality Survey (IMAGES) in Bosnia and Herzegovina, Brazil, Chile, Croatia, Democratic Republic of Congo (DRC), India, Mexico, and Rwanda. Results show that there is wide variation across countries for lifetime self-reported physical violence perpetration (range: 17% in Mexico to 45% in DRC), men's support for equal roles for men and women, and acceptability of violence against women. Across the sample, 31% of men report having perpetrated physical violence against a partner in their lifetime. In multivariate analyses examining risk factors for men ever perpetrating physical violence against a partner, witnessing parental violence was the strongest risk factor, reinforcing previous research suggesting the inter-generational transmission of violence. Additionally, having been involved in fights not specifically with an intimate partner, permissive attitudes towards violence against women, having inequitable gender attitudes, and older age were associated with a higher likelihood of ever perpetrating physical IPV. In separate analyses for each country, we found different patterns of risk factors in countries with high perpetration compared to countries with low perpetration. Findings are interpreted to identify key knowledge gaps and directions for future research, public policies, evaluation, and programming.

    In Sweden 20 000 cases of assault against women are reported to the police every year. All data on the perpetrators of spousal homicide in Sweden between 1990 and 1999 were investigated (n = 164). A control group of all other perpetrators of homicide in Sweden during the same period, i.e. cases of homicide not committed in the context of spouse violence (n = 690) was used. All verdicts, as well as all material in the police investigations, including interviews with all of the police investigators, were analysed. Copies of police examinations of the suspects, and forensic reports from the autopsies, were also examined. Data on all registered criminality were collected from the National Police Register, and in cases where the perpetrators had been subject to forensic psychiatric examinations, those reports were obtained from the Swedish National Board of Forensic Medicine. In addition, the Psychopathy Checklist: Screening Version scores were rated from the forensic psychiatric examinations. There was a four times higher suicide rate among the spousal homicide perpetrators (24%, n = 40) compared with the perpetrators in the control-group (6%, n = 39, chi-squared = 55,42 df = 1, p suicidal ideation must be considered as an important risk factor for spousal homicide. In 79% of the cases the spousal homicide perpetrators were subject to forensic psychiatric examinations. All except 5% were diagnosed with at least one psychiatric diagnosis, and 34% were sentenced to forensic psychiatric treatment. If it is assumed that the psychiatric morbidity was high in the 24% of the perpetrators who committed suicide, then 80% of all perpetrators of spouse homicide during the study period can be characterized as mentally disordered. 'Psychopathic' perpetrators, who generally are over-represented in most violent criminality, were comparatively uncommon. Only seven (4%) in the study group met the diagnostic criteria for psychopathy as measured with the PCL:SV. The group of spouse

    Recent literature reviews show that bullying perpetration and victimization are major public health concerns for typically developing (TD) youth. Nevertheless, the magnitude of this phenomenon among youth with intellectual disabilities (ID) remains unclear. Therefore, the purpose of this review is to provide a synthesis of the empirical studies examining the prevalence and correlates of bullying perpetration and victimization among youth with ID. A systematic literature search was performed and 11 studies met the inclusion criteria. The findings from these studies showed weighted mean prevalence rates of general bullying perpetration, bullying victimization and both of 15.1%, 36.3%, and 25.2%, respectively. Weighted mean prevalence rates of bullying perpetration and victimization differed according to the characteristics of the studies (e.g., assessment context, school setting, information source, type of measures, time frame). Additionally, high weighted mean prevalence rates of physical (33.3%), verbal (50.2%), relational (37.4%), and cyber (38.3%) victimization were found among youth with ID. When youth with ID were compared to youth with other disabilities or TD peers, no clear differences were found. Finally, the present review shows that correlates of bullying perpetration and victimization in this population remain understudied. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Self-reported impulsivity has been found to predict the perpetration of sexual coercion in both sexual offenders and male college students. Impulsivity can be conceptualized as a generalized lack of self-control (i.e., general perspective) or as a multifaceted construct that can vary from one context to the other (i.e., domain-specific perspective). Delay discounting, the tendency to prefer sooner smaller rewards over larger delayed rewards, is a measure of impulsive decision making. Recent sexual adaptations of delay discounting tasks can be used to test domain-specific assumptions. The present study used the UPPS-P impulsivity questionnaire, a standard money discounting task, and a sexual discounting task to predict past use of sexual coercion in a sample of 98 male college students. Results indicated that higher negative urgency scores, less impulsive money discounting, and more impulsive sexual discounting all predicted sexual coercion. Consistent with previous studies, sexuality was discounted more steeply than money by both perpetrators and non-perpetrators of sexual coercion, but this difference was twice as large in perpetrators compared to non-perpetrators. Our study identified three different predictors of sexual coercion in male college students: a broad tendency to act rashly under negative emotions, a specific difficulty to postpone sexual gratification, and a pattern of optimal non-sexual decision making. Results highlight the importance of using multiple measures, including sexuality-specific measures, to get a clear portrait of the links between impulsivity and sexual coercion.

    To test whether experiencing childhood corporal punishment is linked to later perpetration of dating violence. Young adults (n = 758; 61% female; mean age of 20 years), originally recruited for a longitudinal study as 9th- and 10th-grade Texas high school students, were asked about their childhood experiences with corporal punishment and physical abuse, as well as current experiences with dating violence. A path model was used to determine whether childhood corporal punishment was related to recent perpetration of physical dating violence, while controlling for childhood physical abuse, age, sex, ethnicity, and socioeconomic status. In all, 19% of participants (n = 134) reported physical dating violence perpetration and 68% reported experiencing corporal punishment as children (n = 498). Analysis showed a significant positive association between corporal punishment and physical perpetration of dating violence (OR 1.30, 95% CI 1.07-1.59). Even after controlling for sex, ethnicity, age, parental education, and child physical abuse, childhood corporal punishment was associated significantly with physical dating violence perpetration (aOR 1.29, 95% CI 1.02-1.62). The finding that childhood corporal punishment was associated with perpetration of young adult physical dating violence, even after controlling for several demographic variables and childhood physical abuse, adds to the growing literature demonstrating deleterious outcomes associated with corporal punishment.

    This article is based on a review of 60 evaluations (published and unpublished) relating to European domestic violence perpetrator programmes, involving 7,212 programme participants across 12 countries. The purpose of the review, part of the "IMPACT: Evaluation of European Perpetrator Programmes" project funded by the European Commission (Daphne III Programme), was to provide detailed knowledge about the range of European evaluation studies with particular emphasis on the design, methods, input, output, and outcome measures used in order to identify the possibilities and challenges of a multicountry, Europe-wide evaluation methodology that could be used to assess perpetrator programmes in the future. We provide a model to standardise the reporting of evaluation studies and to ensure attention is paid to what information is being collected at different time points so as to understand what and how the behaviour and attitudes of perpetrators might change throughout the course of the programme.

    The present study investigated the predictive utility of self-reported domestic violence perpetrators' exposure to violence in their family of origin and patterns related to this exposure through the use of longitudinal analyses on a sample of 228 men on probation in Lake County, Illinois. Differences in typology, recidivism, recidivism frequency, and violent behavior survival patterns in men with a history of domestic violence perpetration and with varying levels of family of origin violence exposure were examined. Findings suggest that those who witnessed interparental violence (either alone, or in combination with experiencing violence) were most likely to be classified as Generally Violent offenders (e.g., perpetrators who direct violence toward their family and others), compared to those who did not report experiencing or witnessing violence. In addition, results also indicate that men who experienced both witnessing interparental violence and receiving physical abuse in childhood were more likely to recidivate more frequently compared to those who did not report experiencing or witnessing violence. No significant findings for typology and recidivism were noted. Clinical and policy/practice implications are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2005-01-01

    The objective of the study was to explore the possibility of common signs and symptoms of childhood-onset neuropsychiatric disorders and personality disorders, especially psychopathy, in a cohort of violent offenders. A structured neuropsychiatric status comprising features recorded in childhood-onset neuropsychiatric disorders and adult personality disorders was assessed in 89 perpetrators of severe crimes against other persons, analysed for factor structure, and compared to clinical diagnostics of neuropsychiatric disorders and independent assessments of psychopathy rated by the Psychopathy Checklist Revised (PCL-R). One or several childhood-onset neuropsychiatric disorders [autism, attention-deficit/hyperactivity disorder (AD/HD), tics and learning disability] affected the majority of adult offenders. A factor analysis yielded four higher-order problem constellations: Executive Dysfunction, Compulsivity, Social Interaction Problems and Superficiality. All four constellations were positively correlated with life histories of aggression, stressing the clinical importance of these problems in adult forensic psychiatry. Compulsivity and Social Interaction Problems were associated with autistic traits and tics, Executive Dysfunction with AD/HD, conduct disorder and psychopathic as well as autistic traits. Superficiality was a distinct aspect of AD/HD and psychopathic traits, especially the PCL-R factor reflecting interpersonal callousness. Neuropsychiatric disorders and personality disorders such as psychopathy share common symptoms. The various facets of psychopathy are associated with executive dysfunction and empathy deficits with superficial understanding of self, others and the rules of communication.

    This short-term longitudinal study examined whether the association between bullying perpetration and later physical dating violence perpetration and mediators of that association (via anger, depression, anxiety, and social status), varied depending on level of bullying victimization. Differences have been noted between those who bully but are not victims of bullying, and those who are both bullies and victims. These differences may influence dating violence risk and the explanations for why bullying leads to dating violence. Data were from dating adolescents in three rural counties who completed self-administered questionnaires in the fall semester of grades 8–10 and again in the spring semester. The sample (N =2,414) was 44.08% male and 61.31% white. Bullying perpetration in the fall semester predicted physical dating violence perpetration in the spring semester when there was no bullying victimization, but not when there was any bullying victimization. Bullying perpetration was positively associated with anger at all levels of bullying victimization and with social status when there was no or low amounts of victimization; it was negatively associated with social status at high levels of victimization. Bullying victimization was positively associated with anger, depression, and anxiety at all levels of bullying perpetration. Anger mediated the association between bullying perpetration and dating violence, regardless of level of victimization; depression, anxiety, and social status did not mediate the association at any level of bullying victimization. The findings have implications for dating violence prevention efforts and for future research on the link between bullying and dating violence. PMID:26299840

    Despite an emerging body of research indicating that immigrants are less likely than native-born Americans to engage in crime and antisocial behavior, less attention has focused specifically on intimate partner violence (IPV) perpetration among immigrant populations. We address this gap by using data from Wave II of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and compare immigrants from Asia, Africa, Europe, and Latin America to native-born Americans with respect to multiple forms of IPV. After controlling for an extensive array of confounds, results indicate that in the aggregate, immigrants are significantly more likely to perpetrate IPV. However, examination of major world regions indicates these results are driven by Latin American immigrants. Immigrants from Asia, Africa, and Europe report a lower prevalence of IPV perpetration than native-born Americans. This study extends prior research on the immigrant paradox and suggests that future studies take into account regional heterogeneity when examining IPV and other forms of violence in immigrant populations. © The Author(s) 2014.

    Full Text Available The presented study aims to compare men and women (N = 227, perpetrators of domestic violence in terms of psychosocial characteristics, present conditions of socialization in which the perpetrator grew and the motives for committing violent act against partners. The population of violence offenders under study and its sub-groups (women and men did not differ from the norm group in terms of personality traits and temperament. The differences were noticed only in two KSP scales: secure style and avoidance style. The comparison of women and men revealed differences, in three variables: openness for experience, emotional intelligence and avoidance-ambivalence style. Moreover, study showed that despite the good relationship between the subjects’ parents, some perpetrators suffered violence from the loved ones. It should be noted that women were more affected by physical and psychological aggression in childhood. Analysis of motives to commit acts of violence indicated that they are associated with three factors: advantage over your partner, influence and control.

    Research on risk factors for men's perpetration of intimate partner violence (IPV) has shown a high correlation with problem alcohol use. Additional studies, however, indicate that the alcohol-IPV link is neither simple nor necessarily direct and that a range of factors may moderate this relationship. Using a national, community-based sample of 255 men, the present study examined the moderating effects of ambivalent sexism (i.e., hostile and benevolent sexism) on the relationship between alcohol use and IPV perpetration. The findings show that both greater alcohol consumption and high hostile sexism are positively associated with IPV perpetration, and that hostile sexism moderates the alcohol-IPV relationship for perpetration of physical IPV, but not for psychological IPV. Moreover, high levels of alcohol consumption have a greater impact on physical IPV perpetration for men low in hostile sexism than for men high in hostile sexism, lending support to the multiple threshold model of the alcohol-IPV link. Implications of the findings for prevention, intervention, and future research are discussed. © The Author(s) 2015.

    Social ecological and developmental system perspectives suggest that interactions among factors within and across multiple contexts (e.g., neighborhood, peer, family) must be considered in explaining dating violence perpetration. Yet, to date, most extant research on dating violence has focused on individual, rather than contextual predictors, and used variable-centered approaches that fail to capture the configurations of factors that may jointly explain involvement in dating violence. The current study used a person-centered approach, latent profile analysis, to identify key configurations (or profiles) of contextual risk and protective factors for dating violence perpetration across the neighborhood, school, friend and family contexts. We then examine the longitudinal associations between these contextual risk profiles, assessed during middle school, and trajectories of psychological and physical dating violence perpetration across grades 8 through 12. Five contextual risk profiles were identified: school, neighborhood, and family risk; school and family risk; school and friend risk; school and neighborhood risk; and low risk. The highest levels of psychological and physical perpetration across grades 8 through 12 were among adolescents in the profile characterized by high levels of school, neighborhood, and family risk. Results suggest that early interventions to reduce violence exposure and increase social regulation across multiple social contexts may be effective in reducing dating violence perpetration across adolescence.

    2017-07-01

    The literature review analyzed 24 studies that explored male intimate partner violence (IPV) perpetration risk factors among men, in particular Hispanics, using the socioecological model framework composed of four socioecological levels for violence prevention. Six databases were reviewed within the EBSCO search engine for articles published from 2000 to 2014. Articles reviewed were specific to risk factors for IPV perpetration among Hispanic men, focusing particularly on Mexican American men. Many key factors have previously been associated with risk for IPV perpetration; however, certain determinants are unique to Hispanics such as acculturation, acculturation stress, and delineated gender roles that include Machismo and Marianismo. These risk factors should be incorporated in future targeted prevention strategies and efforts and capitalize on the positive aspects of each to serve as protective factors.

    This large, population-based study is one of the few to examine prevalence rates of sexual harassment occurring during the past 12 months by victimization and perpetration among adolescents. In this large, cross-sectional survey of students attending 26 high schools, sexual harassment was defined using three questions from the Sexual Experiences Questionnaire. Among 18,090 students completing the survey, 30% disclosed sexual harassment victimization (37% of females, 21% of males) and 8.5% reported perpetration (5% of females, 12% of males). Sexual harassment perpetration was highly correlated with male sex, minority race/ethnicity, same-sex attraction, bullying, alcohol binge drinking, and intraparental partner violence. © The Author(s) 2014.

    Perpetrators use rape supportive attitudes and sexual assault incident characteristics to justify forcing sex on their victims. Perpetrators who can justify their behaviors are at increased risk for future perpetration. This study examined the relationships between rape supportive attitudes, sexual assault incident characteristics, and the post-assault justifications of 183 men sampled from the community who self-reported committing at least one act of sexual aggression. Hierarchical multiple regression analyses indicated that rape supportive attitudes, expectations for having sex, misperceptions of sexual intent, victims' alcohol consumption, attempts to be alone with her, and the number of consensual sexual activities prior to the unwanted sex were significant predictors of perpetrators' post-assault use of justifications. Greater use of justifications was a significant predictor of sexual aggression over a 1-year follow-up interval. These findings demonstrate the need for further research exploring when and why perpetrators use post-assault justifications and whether they are amenable to change. © The Author(s) 2015.

    A nationally representative study of psychiatric disorders in South Africa provided an opportunity to study the association between perpetration of human rights violations (HRVs) during apartheid and psychiatric disorder. Prior work has suggested an association between perpetration and post-traumatic stress disorder (PTSD), but this remains controversial. Subjects reported on their perpetration of human rights violations, purposeful injury, accidental injury and domestic violence. Lifetime and 12-month prevalence of DSM-IV (Diagnostic and Statistical Manual, 4th edition) disorders were assessed with Version 3.0 of the World Health Organization Composite International Diagnostic Interview (CIDI 3.0). Socio-demographic characteristics of these groups were calculated. Odds ratios for the association between the major categories of psychiatric disorders and perpetration were assessed. HRV perpetrators were more likely to be male, black and more educated, while perpetrators of domestic violence (DV) were more likely to be female, older, married, less educated and with lower income. HRV perpetration was associated with lifetime and 12-month anxiety and substance use disorders, particularly PTSD. Purposeful and DV perpetration were associated with lifetime and 12-month history of all categories of disorders, whereas accidental perpetration was associated most strongly with mood disorders. Socio-demographic profiles of perpetrators of HRV and DV in South Africa differ. While the causal relationship between perpetration and psychiatric disorders deserves further study, it is possible that some HRV and DV perpetrators were themselves once victims. The association between accidental perpetration and mood disorder also deserves further attention.

  18. Understanding cybercrime perpetrators and the strategies they employ in Nigeria.

    A lot has been written on cybercrime and its prevention, but the problem has proved particularly resilient to remedial action. Desperate and vulnerable individuals in every continent continue to fall into its trap. Despite this, there is dearth of descriptive study that attempts to unravel the strategies employed by the perpetrators in Nigeria, as an important precondition for workable and reliable policy direction to address the problem. This article has filled this gap by using data from 40 cybercrime perpetrators selected with snowballing technique. The findings revealed that most of the cybercrime perpetrators in Nigeria are between the age of 22 and 29 years who were undergraduates and have distinctive lifestyles from other youths. Their strategies include collaboration with security agents and bank officials, local and international networking, and the use of voodoo that is, traditional supernatural power. It was clear that most perpetrators of cybercrime were involved in on-line dating and buying and selling with fake identity among others. The article discussed the need for reorientation of Nigerian youths in higher institutions, and various methods as guiding principles for potential victims. It recommended a complete reorganization of the Nigerian Police Force and Economic and Financial Crime Commission, as some of the officers in the institutions aid and abet cybercrime. It finally suggested a review of the Nigerian law guiding the operations of banking, poster agencies, and various speed post services in the country, as these are necessary preconditions to effectively combat the problem.

  2. Exploring Alcohol Policy Approaches to Prevent Sexual Violence Perpetration

    2018-01-01

    Sexual violence continues to be a significant public health problem worldwide with serious consequences for individuals and communities. The implementation of prevention strategies that address risk and protective factors for sexual violence at the community level are important components of a comprehensive approach, but few such strategies have been identified or evaluated. The current review explores one potential opportunity for preventing sexual violence perpetration at the community level: alcohol policy. Alcohol policy has the potential to impact sexual violence perpetration through the direct effects of excessive alcohol consumption on behavior or through the impact of alcohol and alcohol outlets on social organization within communities. Policies affecting alcohol pricing, sale time, outlet density, drinking environment, marketing, and college environment are reviewed to identify existing evidence of impact on rates of sexual violence or related outcomes, including risk factors and related health behaviors. Several policy areas with initial evidence of an association with sexual violence outcomes were identified, including policies affecting alcohol pricing, alcohol outlet density, barroom management, sexist content in alcohol marketing, and policies banning alcohol on campus and in substance-free dorms. We identify other policy areas with evidence of an impact on related outcomes and risk factors that may also hold potential as a preventative approach for sexual violence perpetration. Evidence from the current review suggests that alcohol policy may represent one promising avenue for the prevention of sexual violence perpetration at the community level, but additional research is needed to directly examine effects on sexual violence outcomes.

    Five studies tested the hypothesis that self-regulatory failure is an important predictor of intimate partner violence (IPV) perpetration. Study 1 participants were far more likely to experience a violent impulse during conflictual interaction with their romantic partner than they were to enact a violent behavior, suggesting that self-regulatory processes help individuals refrain from perpetrating IPV when they experience a violent impulse. Study 2 participants high in dispositional self-control were less likely to perpetrate IPV, in both cross-sectional and residualized-lagged analyses, than were participants low in dispositional self-control. Study 3 participants verbalized more IPV-related cognitions if they responded immediately to partner provocations than if they responded after a 10-s delay. Study 4 participants whose self-regulatory resources were experimentally depleted were more violent in response to partner provocation (but not when unprovoked) than were nondepleted participants. Finally, Study 5 participants whose self-regulatory resources were experimentally bolstered via a 2-week training regimen exhibited less violent inclinations than did participants whose self-regulatory resources had not been bolstered. These findings hint at the power of incorporating self-regulation dynamics into predictive models of IPV perpetration. (c) 2009 APA, all rights reserved).

    Studies of rape of women seldom distinguish between men's participation in acts of single and multiple perpetrator rape. Multiple perpetrator rape (MPR) occurs globally with serious consequences for women. In South Africa it is a cultural practice with defined circumstances in which it commonly occurs. Prevention requires an understanding of whether it is a context specific intensification of single perpetrator rape, or a distinctly different practice of different men. This paper aims to address this question. We conducted a cross-sectional household study with a multi-stage, randomly selected sample of 1686 men aged 18-49 who completed a questionnaire administered using an Audio-enhanced Personal Digital Assistant. We attempted to fit an ordered logistic regression model for factors associated with rape perpetration. 27.6 % of men had raped and 8.8 % had perpetrated multiple perpetrator rape (MPR). Thus 31.9 % of men who had ever raped had done so with other perpetrators. An ordered regression model was fitted, showing that the same associated factors, albeit at higher prevalence, are associated with SPR and MPR. Multiple perpetrator rape appears as an intensified form of single perpetrator rape, rather than a different form of rape. Prevention approaches need to be mainstreamed among young men.

    Based on a survey of 9512 ninth-grade students conducted in Lower Saxony in 2013, this paper examines the prevalence of cyberbullying perpetration and the correlates of this behavior. Binary logistic multilevel regression was used in order to analyze correlates of sexual and psychological cyberbully perpetration. In the preceding semester, 2.4% of the adolescents were perpetrators of psychological cyberbullying and 0.4% bullied someone online sexually. Low levels of empathy, frequent consumption of violent media, and being victims of aggressive online behaviors are correlated with the risk that a child will become a bully. Female adolescents are less likely than boys to engage in sexual cyberbullying perpetration, but they are more likely to engage in psychological cyberbullying perpetration. Only a small share of adolescents engage in sexual and psychological cyberbullying perpetration. Both behaviors differ in their correlates, however being a victim of aggressive online behaviors increase the risk for perpetration of both behaviors, respectively. PMID:29415426

    The aim of the present study was to investigate whether the depressive symptoms of the bullied respondents differed according to who the perpetrator was. We used cross-sectional questionnaire data from two representative cohorts: the Danish Working Environment Cohort Study (DWECS 2010) and the Work and Health Study (WH 2012). After excluding respondents not having a leader, or being self-employed, assisting spouses, and those reporting multiple perpetrators in WH 2012, the statistical analysis included 2478 bullied individuals. We compared respondents reporting being bullied by their (1) leader, (2) subordinates, (3) clients / customers / patients / students, or (4) colleagues, respectively. The occurrence of depressive symptoms was measured by the Major Depression Inventory (MDI). The most frequent perpetrator of bullying was clients (41.5 %) in DWECS 2010 and colleagues (60.3 %) in WH 2012. In DWECS 2010, the MDI score of those being bullied by clients were significantly lower than the MDI scores of the other groups. In WH 2012, respondents who reported bullying from leaders had a significantly higher mean MDI score than participants being bullied by colleagues. Also in WH 2012, our results indicated that those who were bullied by leaders had a higher MDI score than those bullied by clients, although this difference was not statistically significant at conventional levels. Our findings indicated a similar pattern in the two cohorts, with a tendency of more severe depressive symptoms among employees who are exposed to bullying by their leaders, and the least severe symptoms among those who are bullied by clients.

    Significant rates of intimate partner violence (IPV) perpetration have been identified among men with military backgrounds. Research indicates posttraumatic stress symptoms place military men at increased risk for IPV perpetration, but may be negatively associated with IPV among nonmilitary samples. However, no previous studies have directly compared court-referred IPV offenders with and without military experience, which may have clinical implications if posttraumatic stress symptoms are differentially associated with IPV perpetration across these two samples. Twenty court-referred IPV offenders with military background were demographically matched with 40 court-referred IPV offenders without military background. As anticipated, self- and partner-report of physically assaultive acts and injurious acts during baseline assessment showed significantly greater physical assault and injury perpetrated by offenders with military background. However, 1-year follow-up data on convictions indicated a significantly lower rate of recidivism among offenders with military background than among nonmilitary offenders. As hypothesized, symptoms of posttraumatic stress at intake showed a significant positive correlation with IPV perpetration among offenders with military background; however, this relationship showed a negative correlation among offenders without military background. Clinical implications are discussed including treatment avenues, such as Veterans Courts and other incarceration diversion programs, which may be particularly appropriate for offenders with military backgrounds.

    The case of a young woman with still ongoing incest and forced prostitution is presented. The criteria for a dissociative identity disorder (DID) were met. Due to persistent contact to the perpetrator she was repeatedly revictimized. Based on the model of trauma-related dissociation we discuss to what extent she was capable of self-determined decision making as well as therapeutic consequences resulting therefrom. © Georg Thieme Verlag KG Stuttgart · New York.

    The rise in homicides by those with serious mental illness is of concern, although this increase may not be continuing. To examine rates of mental illness among homicide perpetrators. A national consecutive case series of homicide perpetrators in England and Wales from 1997 to 2006. Rates of mental disorder were based on data from psychiatric reports, contact with psychiatric services, diminished responsibility verdict and hospital disposal. Of the 5884 homicides notified to the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness between 1997 and 2006, the number of homicide perpetrators with schizophrenia increased at a rate of 4% per year, those with psychotic symptoms at the time of the offence increased by 6% per year. The number of verdicts of diminished responsibility decreased but no change was found in the number of perpetrators receiving a hospital order disposal. The likeliest explanation for the rise in homicide by people with psychosis is the misuse of drugs and/or alcohol, which our data show increased at a similar magnitude to homicides by those with psychotic symptoms. However, we are unable to demonstrate a causal association. Although the Poisson regression provides evidence of an upward trend in homicide by people with serious mental illness between 1997 and 2006, the number of homicides fell in the final 2 years of data collection, so these findings should be treated with caution. There appears to be a concomitant increase in drug misuse over the period, which may account for this rise in homicide. However, an increase in the number of people in contact with mental health services may suggest that access to mental health services is improving. Previous studies have used court verdicts such as diminished responsibility as a proxy measure of mental disorder. Our data indicate that this does not reflect accurately the prevalence of mental disorder in this population.

    Objectives. We examined correlations between gender, race, sexual identity, and technology use, and patterns of cyberbullying experiences and behaviors among middle-school students. Methods. We collected a probability sample of 1285 students alongside the 2012 Youth Risk Behavior Survey in Los Angeles Unified School District middle schools. We used logistic regressions to assess the correlates of being a cyberbully perpetrator, victim, and perpetrator–victim (i.e., bidirectional cyberbullying behavior). Results. In this sample, 6.6% reported being a cyberbully victim, 5.0% reported being a perpetrator, and 4.3% reported being a perpetrator–victim. Cyberbullying behavior frequently occurred on Facebook or via text messaging. Cyberbully perpetrators, victims, and perpetrators–victims all were more likely to report using the Internet for at least 3 hours per day. Sexual-minority students and students who texted at least 50 times per day were more likely to report cyberbullying victimization. Girls were more likely to report being perpetrators–victims. Conclusions. Cyberbullying interventions should account for gender and sexual identity, as well as the possible benefits of educational interventions for intensive Internet users and frequent texters.

    Preventing intimate partner violence (IPV) is a public health priority. An important component of designing prevention programs is developing an understanding of how media portrayals of health issues influence public opinion and policy. To better understand the ways in which media images may be informing our understanding of IPV, this study content analyzed portrayals of IPV in news media articles. Stratified media outlets were used to obtain a representative sample of daily newspapers based on their designated market areas. Researchers created constructed months using weeks from each season across a 2-year period. The first part of the study investigated quantitative differences in the coverage of female and male perpetrators (n = 395) and identified several areas where coverage differed. The second part of the study qualitatively examined coverage of female perpetrators (n = 61) to provide a richer description of such coverage. This study contributes to our understanding of female perpetrators and how these portrayals may contribute to the larger gender symmetry debate surrounding female aggressors. Implications for public health policy and research are discussed. © The Author(s) 2014.

    Loewenau, Aleksandra; Weindling, Paul J

    Issues relating to the euthanasia killings of the mentally ill, the medical research conducted on collected body parts, and the clinical investigations on living victims under National Socialism are among the best-known abuses in medical history. But to date, there have been no statistics compiled regarding the extent and number of the victims and perpetrators, or regarding their identities in terms of age, nationality, and gender. "Victims of Unethical Human Experiments and Coerced Research under National Socialism," a research project based at Oxford Brookes University, has established an evidence-based documentation of the overall numbers of victims and perpetrators through specific record linkages of the evidence from the period of National Socialism, as well as from post-WWII trials and other records. This article examines the level and extent of these unethical medical procedures as they relate to the field of neuroscience. It presents statistical information regarding the victims, as well as detailing the involvement of the perpetrators and Nazi physicians with respect to their post-war activities and subsequent court trials.

    Full Text Available Abstract Background Multiple Sclerosis (MS is an incurable, chronic, potentially progressive and unpredictable disease of the central nervous system. The disease produces a range of unpleasant and debilitating symptoms, which can have a profound impact including disrupting activities of daily living, employment, income, relationships, social and leisure activities, and life goals. Adjusting to the illness is therefore particularly challenging. This trial tests the effectiveness of a Cognitive Behavioural intervention compared to Supportive Listening to assist adjustment in the early stages of MS. Methods/Design This is a two arm randomized multi-centre parallel group controlled trial. 122 consenting participants who meet eligibility criteria will be randomly allocated to receive either Cognitive Behavioral Therapy or Supportive Listening. Eight one hour sessions of therapy (delivered over a period of 10 weeks will be delivered by general nurses trained in both treatments. Self-report questionnaire data will be collected at baseline (0 weeks, mid-therapy (week 5 of therapy, post-therapy (15 weeks and at six months (26 weeks and twelve months (52 weeks follow-up. Primary outcomes are distress and MS-related social and role impairment at twelve month follow-up. Analysis will also consider predictors and mechanisms of change during therapy. In-depth interviews to examine participants' experiences of the interventions will be conducted with a purposively sampled sub-set of the trial participants. An economic analysis will also take place. Discussion This trial is distinctive in its aims in that it aids adjustment to MS in a broad sense. It is not a treatment specifically for depression. Use of nurses as therapists makes the interventions potentially viable in terms of being rolled out in the NHS. The trial benefits from incorporating patient input in the development and evaluation stages. The trial will provide important information about the

    IMPORTANCE Sexual violence can emerge in adolescence, yet little is known about youth perpetrators-especially those not involved with the criminal justice system. OBJECTIVE To report national estimates of adolescent sexual violence perpetration and details of the perpetrator experience. DESIGN, SETTING, AND PARTICIPANTS Data were collected online in 2010 (wave 4) and 2011 (wave 5) in the national Growing Up With Media study. Participants included 1058 youths aged 14 to 21 years who at baseline read English, lived in the household at least 50% of the time, and had used the Internet in the last 6 months. Recruitment was balanced on youths' biological sex and age. MAIN OUTCOMES AND MEASURES Forced sexual contact, coercive sex, attempted rape, and completed rape. RESULTS Nearly 1 in 10 youths (9%) reported some type of sexual violence perpetration in their lifetime; 4% (10 females and 39 males) reported attempted or completed rape. Sixteen years old was the mode age of first sexual perpetration (n = 18 [40%]). Perpetrators reported greater exposure to violent X-rated content. Almost all perpetrators (98%) who reported age at first perpetration to be 15 years or younger were male, with similar but attenuated results among those who began at ages 16 or 17 years (90%). It is not until ages 18 or 19 years that males (52%) and females (48%) are relatively equally represented as perpetrators. Perhaps related to age at first perpetration, females were more likely to perpetrate against older victims, and males were more likely to perpetrate against younger victims. Youths who started perpetrating earlier were more likely than older youths to get in trouble with caregivers; youths starting older were more likely to indicate that no one found out about the perpetration. CONCLUSIONS AND RELEVANCE Sexual violence perpetration appears to emerge earlier for males than females, perhaps suggesting different developmental trajectories.

    Full Text Available We present in this work a new type of classes discriminator based upon nonlinear and combinational optimization techniques: radial basis functions-simulated annealing (RBF-SA. The combinational optimization method is used here as a preestimation of some parameters of the network classifier. We compare the classifier performance with and without pre-estimation. For training the classifiers, adopting the leave-one-out procedure, we have used case examples such as mammographic masses (malignant and benign. The classifier is trained with shape factors and edge-sharpness measures extracted from 57 regions of interest (ROI (37 malignant and 20 benign, manually delineated, that describe mammographic masses and tumor features in terms of polygonal models for shape factors (compactness [CC], Fourier description [FF], fractional concavity [FCC] and speculated index [SI] and edge sharpness-acutance (A . The classifier performance is compared in terms of the area under the receive operating characteristic (ROC curve – (A. Higher values of A correspond to a better performance of classifier. Experiments with mammographic tumor and masses show that the best result of 0.9776 is obtained with RBF-SA when RBF parameters such as centers and spread matrix are pre-estimated, which is significantly better than the results obtained with no pre-estimation or only pre-estimation of the RBF centers, which are, 0.7071 and 0.9552 respectively.

    Lee, Mary; Reese-Weber, Marla; Kahn, Jeffrey H

    2014-01-01

    This study examined a multiple mediator model explaining how sibling perpetration and one's attachment style mediate the relation between parent-to-child victimization and dating violence perpetration. A sample of undergraduate students (n = 392 women, n = 89 men) completed measures of the aforementioned variables on an Internet survey. For men, path analyses found no mediation; parent-to-child victimization had a direct association with dating violence perpetration, no association was found between sibling perpetration and dating violence perpetration, and attachment anxiety, but not attachment avoidance, was positively associated with dating violence perpetration for men. For women, the hypothesized mediation model was supported; parent-to-child victimization had a direct association with dating violence perpetration, and sibling perpetration and attachment anxiety served as mediating variables. Attachment avoidance was not associated with dating violence perpetration for women. Implications for future research and clinical practice are discussed.

    Preliminary research suggests that partner violence is a problem among lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) college youth. However, there is no study to date with college youth on the factors associated with perpetration of same-sex partner violence, which is needed to inform prevention efforts specific to this population. Thus, the purpose of the current study was to assess how facets of minority stress (i.e., sexual-orientation-related victimization, sexual minority stigma, internalized homonegativity, sexual identity concealment) relate to physical, sexual, and psychological partner violence perpetration among LGBTQ college youth (N = 391; 49% identified as men; 72% Caucasian; M age: 20.77 years). At the bivariate level, physical perpetration was related to identity concealment and internalized homonegativity; sexual perpetration was related to internalized homonegativity; and psychological perpetration was related to sexual-orientation-related victimization. However, at the multivariate level (after controlling for concurrent victimization), psychological perpetration was unrelated to minority stress variables, whereas physical and sexual perpetration were both related to internalized homonegativity; physical perpetration was also related to identity concealment. These results underscore the utility of understanding partner violence among LGBTQ youth through a minority stress framework. Moreover, the current study highlights the need for a better understanding of factors that mediate and moderate the relationship between minority stress and partner violence perpetration among LGBTQ youth in order to inform prevention and intervention efforts.

    Although we know much about the effects of violence on victims, we know less about individuals who perpetrate violence. In the present study, we used a large, nationally representative sample of adults (National Comorbidity Study-Replication; n = 9,282) to examine demographics (i.e., age and gender) and social, occupational, and cognitive functioning among perpetrators of recent violence. We found that recent violence was more prevalent among younger individuals and males (i.e., these groups were more likely to engage in at least one act of violence). Among those who did engage in violence, there was no effect of age or gender on violence frequency (i.e., number of violent acts engaged in over the past year). Furthermore, gender moderated the effect of age on recent violence prevalence, but not violence frequency. Finally, those reporting violence over the past year showed greater impairment in all examined domains of functioning, but there was no association between impairment and frequency of violence. This study represents one of the first attempts to utilize 12-month prevalence data to explore the lifetime trajectory of violence among those who perpetrate it, which seems to peak in young adulthood and then decrease across the life span. Furthermore, although males are more likely to engage in violence than females, adults who engage in at least one act of violence demonstrate no difference in frequency of yearly violent acts, regardless of gender. Finally, it is apparent that merely engaging in any acts of violence over the past year is associated with functioning problems. Overall, most significant differences emerged between those who do and do not engage in violence, which is key for informing violence risk assessment and prevention.

    Theory and research suggest that there may be significant heterogeneity in the development, manifestation, and consequences of adolescent dating violence that is not yet well understood. The current study contributed to our understanding of this heterogeneity by identifying distinct patterns of involvement in psychological, physical, and sexual dating violence victimization and perpetration in a sample of Latino youth (n = 201; M = 13.87 years; 42% male), a group that is understudied, growing, and at high risk for involvement in dating violence. Among both boys and girls, latent class analyses identified a three-class solution wherein the largest class demonstrated a low probability of involvement in dating violence across all indices ("uninvolved"; 56% of boys, 64% of girls) and the smallest class demonstrated high probability of involvement in all forms of dating violence except for sexual perpetration among girls and physical perpetration among boys ("multiform aggressive victims"; 10% of boys, 11% of girls). A third class of "psychologically aggressive victims" was identified for which there was a high probability of engaging and experiencing psychological dating violence, but low likelihood of involvement in physical or sexual dating violence (34% of boys, 24% of girls). Cultural (parent acculturation, acculturation conflict), family (conflict and cohesion) and individual (normative beliefs, conflict resolution skills, self-control) risk and protective factors were associated with class membership. Membership in the multiform vs. the uninvolved class was concurrently associated with emotional distress among girls and predicted emotional distress longitudinally among boys. The results contribute to understanding heterogeneity in patterns of involvement in dating violence among Latino youth that may reflect distinct etiological processes.

    The aim of this study was to describe contextual events, abuse experiences, and disclosure processes of adolescents who presented to a hospital-based Child Advocacy Center for medical evaluation and evidentiary collection as indicated after experiencing multiple perpetrator rape during a single event (n=32) and to compare these findings to a group of single perpetrator sexual assaults (n=534). This study used a retrospective mixed-methods design with in-depth, forensic interviews and complete physical examinations of gang-raped adolescents. Patients ranged from 12 to 17 years (M=14 years). Girls who experienced multiple perpetrator rape during a single event were more likely to have run away, to have drunk alcohol in the past month, and to have participated in binge drinking in the past 2 weeks. Acute presentation of these victims were rare but 30% had hymenal transections and 38% had sexually transmitted infections (STIs). Forensic interviews revealed alcohol was a common weapon used by offenders, and its use resulted in victims experiencing difficulty in remembering and reporting details for police investigation or physical and mental health care. Most victims were raped at parties they attended with people they thought they could trust, and they felt let down by witnesses who could have helped but did not intervene. Although relatively rare, multiple perpetrator rape during a single event is a type of severe sexual assault experience and has significant risks for deleterious health outcomes. These victims require health care by trained providers to diagnose physical findings, treat STIs, screen for trauma, and support victims. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    The purpose of the current article was to examine the adolescent risk and protective factors (at the individual, peer group, and family level) for young adult cyberbullying perpetration and victimization. Data from 2006 (Grade 9) to 2010 (young adulthood) were analyzed from a community sample of 927 Victorian students originally recruited as a statewide representative sample in Grade 5 (age, 10-11 years) in 2002 and followed-up to age 18-19 years in 2010 (N = 809). Participants completed a self-report survey on adolescent risk and protective factors and traditional and cyberbullying perpetration and victimization and young adult cyberbullying perpetration and victimization. As young adults, 5.1% self-reported cyberbullying perpetration only, 5.0% reported cyberbullying victimization only, and 9.5% reported both cyberbullying perpetration and victimization. In fully adjusted logistic regression analyses, the adolescent predictors of cyberbullying perpetration only were traditional bullying perpetration, traditional bullying perpetration and victimization, and poor family management. For young adulthood cyberbullying victimization only, the adolescent predictor was emotion control. The adolescent predictors for young adult cyberbullying perpetration and victimization were traditional bullying perpetration and cyberbullying perpetration and victimization. Based on the results of this study, possible targets for prevention and early intervention are reducing adolescent involvement in (traditional or cyber) bullying through the development of social skills and conflict resolution skills. In addition, another important prevention target is to support families with adolescents to ensure that they set clear rules and monitor adolescents' behavior. Universal programs that assist adolescents to develop skills in emotion control are warranted. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Full Text Available Gulsen Unlu, Burcu Cakaloz Department of Child and Adolescent Psychiatry, Faculty of Medicine, Pamukkale University, Denizli, Turkey Purpose: Child sexual abuse and sexual dating violence victimization are common problems that are known to have long-term negative consequences. This study aimed to compare the sociodemographic, abuse-related, and clinical features of female adolescents who were sexually abused by different perpetrators, and identify the factors associated with suicidality and nonsuicidal self-injury (NSSI in these cases. Patients and methods: Data of 254 sexually abused female adolescents between the ages of 12–18 years were evaluated. The cases were classified into three groups, namely “sexual dating violence”, “incest”, and “other child sexual abuse”, according to the identity of the perpetrator. The three groups were compared in terms of sociodemographic, abuse-related, and clinical features. Results: Major depressive disorder was the most common psychiatric diagnosis, which was present in 44.9% of the cases. Among all victims, 25.6% had attempted suicide, 52.0% had suicidal ideation, and 23.6% had NSSI during the postabuse period. A logistic regression analysis revealed that attempted suicide was predicted by dating violence victimization (adjusted odds ratio [AOR] =3.053; 95% confidence interval [CI] =1.473, 6.330 and depression (AOR =2.238; 95% CI =1.226, 4.086. Dating violence victimization was also the strongest predictor of subsequent suicidal ideation (AOR =3.500; 95% CI =1.817, 6.741. In addition, revictimization was determined to be an important risk factor for both suicidal ideation (AOR =2.897; 95% CI =1.276, 6.574 and NSSI (AOR =3.847; 95% CI =1.899, 7.794. Conclusion: Perpetrator identity and revictimization are associated with negative mental health outcomes in sexually victimized female adolescents. Increased risk of suicidality and NSSI should be borne in mind while assessing cases with dating

    Bullying perpetration and sexual harassment perpetration among adolescents are major public health issues. However, few studies have addressed the empirical link between being a perpetrator of bullying and subsequent sexual harassment perpetration among early adolescents in the literature. Homophobic teasing has been shown to be common among middle school youth and was tested as a moderator of the link between bullying and sexual harassment perpetration in this 2-year longitudinal study. More specifically, the present study tests the Bully–Sexual Violence Pathway theory, which posits that adolescent bullies who also participate in homophobic name-calling toward peers are more likely to perpetrate sexual harassment over time. Findings from logistical regression analyses (n = 979, 5th–7th graders) reveal an association between bullying in early middle school and sexual harassment in later middle school, and results support the Bully–Sexual Violence Pathway model, with homophobic teasing as a moderator, for boys only. Results suggest that to prevent bully perpetration and its later association with sexual harassment perpetration, prevention programs should address the use of homophobic epithets. PMID:25315484

    This study compares the motivations for using violence and the context in which violence occurs among male and female domestic violence perpetrators. One hundred twenty-five participants in batterer intervention counseling in Los Angeles County, California, were surveyed. The sample was approximately half male and half female. Males and females were found to differ in their motivations for using violence in relationships. Females reported using violence in response to prior abuse, citing revenge and retaliation as a primary motivation. Because treatment approaches are commonly derived from the power and control model, which indicates that violence is used to gain power and control, batterer intervention counseling may not be appropriate for women, who appear more motivated by the desire to maintain personal liberties in a relationship where they have been victimized. Treatment must walk the fine line between addressing victimization issues and holding women accountable for decisions to use violence.

    Employee Assistance Programs (EAPs) are workplace resources available to employees with problems impacting work performance. EAPs are well-positioned to address intimate partner violence (IPV), a major public health problem with workplace impacts. A purposeful sample of 28 EAPs across the United States was surveyed to identify policies and programs to address IPV, including perpetration. Most EAPs did not report having standardized approaches for addressing IPV perpetration. EAPs also described significant barriers to identifying IPV perpetrators, with the majority relying on self-disclosure on the part of the perpetrator when contacting the EAP. These results suggest that many EAPs--even when interacting with employees who present with issues known to correlate with IPV--are missing a potential opportunity to assess and intervene with IPV perpetrators.

    Full Text Available Este artigo origina-se de uma pesquisa qualitativa que analisou representações sociais relacionadas ao direito à saúde de usuários de dois serviços de saúde mental: um constituído e funcionando com participação de usuários e familiares e outro sem essa participação, visando conhecê-las não apenas vinculadas à consciência do direito à saúde, mas também a fatores associados, como: participação popular, o processo de adoecimento; o atendimento público de saúde, percepção da capacidade de intervenção social, e concepções sobre o Estado. As representações sociais encontradas associadas ao direito à saúde implicam expectativas de que o sistema de saúde e o Estado cumpram funções de acolhimento e amparo. Os usuários do serviço sem participação popular tendem a ser mais conformados e pessimistas. O grupo com participação popular vê o serviço que construiu como possuidor das características negadas pelo sistema oficial e percebe como possível a ação reivindicativa, podendo ser um foco alternativo na formação de novas representações sociais.The present paper originated from a qualitative study that analyzed social representations related to the right to health, expressed by users of two types of mental health services, one with participation by users and families and the other without such participation. The aim was to analyze such representations not only in relation to the awareness of the right to health, but also concerning associated factors, such as: popular participation; illness; public health care; perception of social intervention capacity; and concepts concerning the state. Social representations of the right to health involve expectations that the health system and the state meet their roles of ensuring care and support. Users of the mental health service without user/family participation tended to be more resigned and pessimistic. The group with participation views the service it has built

    Interventions to prevent rape perpetration must be designed to address its drivers. This paper seeks to extend understanding of drivers of single and multiple perpetrator rape (referred to here as SPR and MPR respectively) and the relationships between socio-economic status, childhood trauma, peer pressure, other masculine behaviours and rape. 1370 young men aged 15 to 26 were interviewed as part of the randomised controlled trial evaluation of Stepping Stones in the rural Eastern Cape. We used multinomial to compare the characteristics of men who reported rape perpetration at baseline. We used structural equation modelling (SEM) to examine pathways to rape perpetration. 76.1% of young men had never raped, 10.0% had perpetrated SPR and 13.9% MPR. The factors associated with both MPR and SPR (compared to never having raped) were indicators of socio-economic status (SES), childhood trauma, sexual coercion by a woman, drug and alcohol use, peer pressure susceptibility, having had transactional sex, multiple sexual partners and being physically violent towards a partner. The SEM showed the relationship between SES and rape perpetration to be mediated by gender inequitable masculinity. It was complex as there was a direct path indicating that SES correlated with the masculinity variable directly such that men of higher SES had more gender inequitable masculinities, and indirect path mediated by peer pressure resistance indicated that the former pertained so long as men lacked peer pressure resistance. Having a higher SES conveyed greater resistance for some men. There was also a path mediated through childhood trauma, such that men of lower SES were more likely to have a higher childhood trauma exposure and this correlated with a higher likelihood of having the gender inequitable masculinity (with or without the mediating effect of peer pressure resistance). Both higher and lower socio-economic status were associated with raping. Prevention of rape perpetration must

    The authors examined the backgrounds and social experiences of female terrorists to test conflicting accounts of the etiology of this offending group. Data on 222 female terrorists and 269 male terrorists were examined across 8 variables: age at first involvement, educational achievement, employment status, immigration status, marital status, religious conversion, criminal activity, and activist connections. The majority of female terrorists were found to be single, young (terrorism, but they were more likely to have a higher education attainment, less likely to be employed, and less likely to have prior activist connections. The results clarify the myths and realities of female-perpetrated terrorism and suggest that the risk factors associated with female involvement are distinct from those associated with male involvement.

    To develop a conceptual computational agent-based model (ABM) to explore community-wide versus spatially focused crime reporting interventions to reduce community crime perpetrated by youth. Agents within the model represent individual residents and interact on a two-dimensional grid representing an abstract nonempirically grounded community setting. Juvenile agents are assigned initial random probabilities of perpetrating a crime and adults are assigned random probabilities of witnessing and reporting crimes. The agents' behavioral probabilities modify depending on the individual's experience with criminal behavior and punishment, and exposure to community crime interventions. Cost-effectiveness analyses assessed the impact of activating different percentages of adults to increase reporting and reduce community crime activity. Community-wide interventions were compared with spatially focused interventions, in which activated adults were focused in areas of highest crime prevalence. The ABM suggests that both community-wide and spatially focused interventions can be effective in reducing overall offenses, but their relative effectiveness may depend on the intensity and cost of the interventions. Although spatially focused intervention yielded localized reductions in crimes, such interventions were shown to move crime to nearby communities. Community-wide interventions can achieve larger reductions in overall community crime offenses than spatially focused interventions, as long as sufficient resources are available. The ABM demonstrates that community-wide and spatially focused crime strategies produce unique intervention dynamics influencing juvenile crime behaviors through the decisions and actions of community adults. It shows how such models might be used to investigate community-supported crime intervention programs by integrating community input and expertise and provides a simulated setting for assessing dimensions of cost comparison and intervention effect

    Exposure to violence in the family-of-origin has consistently been linked to intimate partner violence (IPV) perpetration in adulthood. However, whether the transmission of violence across generations is role- and gender-specific still remains unclear. The current study examined the effects of experiencing child abuse and observing parental violence on IPV perpetration among a sample of male arrestees (N = 303). The differential effects of observing violence perpetrated by same-sex (father to mother), opposite-sex (mother to father), and both parents on subsequent IPV perpetration were examined. Logistic regression analyses showed that while observing father-only violence and bidirectional interparental violence was predictive of IPV perpetration, observing mother-only violence and direct experiences of child abuse was not. These findings suggest that the transmission of violence across generations is both role- and gender-specific and highlight the importance of examining unique dimensions of partner violence to assess influences on children. The study further examined whether attitudes justifying wife beating mediate the effect of exposure to violence and subsequent IPV perpetration. Results showed that although attitudes were predictive of perpetration, these attitudes did not mediate the relationship. © The Author(s) 2014.

    This study investigated criminological, psychopathological, and victimological profiles of intimate partner violence (IPV) perpetrators in a sample of 119 Dutch female and male forensic psychiatric outpatients aged 18 to 58 years. In addition, differences in criminological, psychopathological, and victimological factors between IPV perpetrators (n = 61, 51.3%) and non-intimate violence (NIV) perpetrators (n = 58, 48.7%) were examined. All data, including information on demographics, criminal history, history of psychological, sexual, and physical victimization during childhood or adolescence, family history of psychopathology, history of psychopathology in childhood and adolescence, and mental disorders, were derived from archival electronic medical records. Mental disorders were measured using structured psychiatric interviews and final consensus diagnoses were established during weekly case consultations. Both IPV and NIV perpetrators displayed high rates of criminal history, psychopathology, and previous victimization, but the two groups did not differ in these factors with two exceptions. IPV perpetrators were significantly more likely to have higher rates of previous physical victimization and intermittent explosive disorder than NIV perpetrators. The current study suggests that a history of physical victimization and intermittent explosive disorder are specific characteristics of IPV perpetrators in a forensic psychiatric outpatient setting. Future research should focus on mechanisms explaining the association of childhood victimization and IPV and increase our understanding of the role of intermittent explosive disorder in IPV. © The Author(s) 2014.

    To add to our understanding of change processes by analyzing perpetrators' perspectives on intervention. Fourteen databases were searched and 27 articles reporting relevant qualitative findings were identified. Analytic coding was applied across the findings and discussion sections of all 27 study reports to form an interpretive account of the data set. Studies were also grouped according to their perceived theoretical standpoints, and a summary of themes in each grouping is presented. Study participants were largely positive about their experiences in intervention; new learning such as conflict interruption techniques and new communication skills were commonly cited benefits. Perpetrators attend perpetrator intervention programs with a range of motivations, ranging from a determination to change who they are, to a determination to avoid a custodial sentence. The most common barriers to change, found in this analysis, were cognitive distortions, emotional dysregulation, gendered social constructions, and self-esteem issues. Further qualitative investigation, of rigor, with the intention-to-treat population of intimate partner violence perpetrators involved in perpetrator programs is needed. At this point, we would venture that qualitative research, with perpetrators, underlines the precept that formidable barriers to change exist in this population. The centrality of group work to perpetrator interventions should be reconsidered in light of the complexity of the change task and in light of the heterogeneity of this population.

    Sexual coercion among adolescent boys in South Africa is an underresearched topic despite the frequency of such events. Although quantitative research has illuminated the prevalence of sexual coercion toward boys, it has provided little understanding of the context of sexual coercion for adolescent boys. Given the often severe consequences of sexual coercion, it is important to further understand these experiences to inform prevention efforts. The current study aims to provide a more nuanced understanding of the context of sexual coercion. Data come from the baseline assessment for a translational research evaluation of a school-based intervention. The current study focuses on a subset of early and middle adolescent boys who reported experiencing sexual coercion ( n = 223). Analyses examine boys' reports of their perpetrators' characteristics and details about the sexual coercion encounter. Logistic regression is used to examine how coercion tactics used by the perpetrator differs depending on the perpetrator's age and gender. Eighth-grade boys were most likely to report that their perpetrator was a similar-aged female and that perpetrator's age played a particularly important role in what tactics were used. Adult perpetrators were more likely to use physical force, threaten them, harass them electronically, and drink or use drugs at the time. Results provide important insight into boys' experiences of sexual coercion that have implications for both future research and intervention efforts. Although much research is needed on the topic, intervention programs should recognize that both male and female adolescents can be victim and perpetrator.

    Dating violence is commonly perpetrated in adolescence, making it imperative to understand risk factors in order to inform prevention efforts. Although individual norms supporting dating violence are strongly related to its perpetration, few studies have examined their longitudinal impact. Moreover, the influence of class norms (i.e., norms for students in the same grade, cohort, and school) supporting dating violence on perpetration has rarely been studied. The current study examined longitudinal relationships between individual and class norms supporting dating violence and perpetration of physical and psychological dating violence. Participants were two cohorts of sixth graders from 37 schools who were in dating relationships at Wave 1 and 6 months later at Wave 2 (N = 2,022; 43% female; 52% African American, 21% Latino/a, 20% White, and 7% other). The analyses used a multilevel approach, with students represented at Level 1 and classes (n = 74) at Level 2. The models tested direct effects of Wave 1 individual and class norms supporting dating violence on subsequent changes in perpetration of dating violence at Wave 2 and the extent to which gender moderated these relationships. The findings indicated that greater individual norms supporting male dating violence predicted greater change in perpetration of physical and psychological dating violence and greater individual norms supporting female dating violence predicted greater change in perpetration of psychological dating violence. Greater class norms supporting male dating violence predicted greater change in perpetration of physical dating violence; whereas greater class norms supporting female dating violence predicted less change in perpetration of physical dating violence. These findings highlight the need to address norms in early adolescence.

    Cyberbullying research in China is in early stage. This study describes the cyberbullying experiences of junior and senior high school students in Guangzhou, China, and to examine the risk factors associated with cyberbullying perpetrators, victims and perpetrator-victims among students. We also investigated the frequency of cyberbullying and coping strategies of student victims. Participants were 2590 students in grades 7, 8, 9 and 10 from six junior and senior high schools in October 2015 in Guangzhou, in south China, who completed a questionnaire. Data on participants' experiences with cyberbullying perpetration and victimisation during the previous 6 months were collected. Multinomial logistic regression was used to analyse factors associated with being perpetrators, victims and perpetrator-victims. In this sample, 28.0% (725) of participants reported being a perpetrator and 44.5% (1150) reported being a victim in the previous 6 months. Specifically, 2.9% (74) reported being perpetrators only, 19.3% (499) reported being victims only and 25.2% (651) reported being perpetrator-victims (both perpetrator and victim). In addition, flaming was the most common form of cyberbullying in both perpetration and victimisation. Logistic regression analyses indicated that online game addiction in participants was associated with increased odds of being a perpetrator only; no democratic parenting style in the mother and physical discipline by parents were associated with increased odds of being a victim only; male students, students with low academic achievement, those spending over 2 hours a day online, experiencing physical discipline from parents and online game addiction were associated with increased odds of both perpetration and victimisation. Cyberbullying is a common experience among Chinese junior and senior high school students. These findings add to the empirical data on cyberbullying and reinforce the urgent need for cyberbullying prevention in China

    Research on sexual violence victims and perpetrators indicates that victims in general are found to report higher levels of psychopathological symptoms, especially internalizing behavior, whereas perpetrators often show externalizing behavior. Little is known, however, about the psychopathology of perpetrators of sexual violence who have also experienced sexual victimization (victim-perpetrators). Thus, the aim of the current study was to examine this group within a sample of adolescents living in residential care or federal boarding schools. Participants reported their lifetime experience with sexual violence (both as victim and perpetrator) and completed the Youth Self Report. Results indicate that all three groups of adolescents with sexual violence experience report higher total problem scores than adolescents without this experience. Victim-perpetrators show results more similar to those of perpetrators only than those of victims only. The discussion deals with the implications of our findings for the treatment of victims of sexual violence.

    The aims of this study were (1) to examine differences in the level of self-esteem among adolescents with different roles in aggression involvement (aggression perpetrators, victims, perpetrator-victims and neutrals) according to gender and (2) to examine the moderating effects of depression and family support on association between aggression involvement and self-esteem. A total of 8085 adolescents in Taiwan completed questionnaires. The relationships between self-esteem and aggression involvement were examined by multiple regression analysis. The moderating effects of depression and family support on the association between aggression involvement and self-esteem were examined. The results showed that in females, aggression victims had lower self-esteem than those in the other three groups (t=-2.940 to 2.173, p0.05). In males, self-esteem in victims and perpetrator-victims was lower than in neutrals and perpetrators (t=-3.339 to -2.704, p0.05) or between perpetrators and neutrals (t=-1.396, p>0.05). Family support had a moderating effect on the association between self-esteem and victimization in males. Depression had a moderating effect on the association between self-esteem and perpetration-victimization and victimization in males. The results indicate that self-esteem in adolescents with different patterns of involvement in aggression is not the same as in those without involvement. The moderating effects of depression and family support should be considered when developing intervention strategies to raise self-esteem in adolescents with aggression involvement. Copyright © 2012.

Bullying involvement, family and ADHD characteristics, the levels of behavioral inhibition system (BIS) and behavioral approach system (BAS), and psychiatric comorbidity were assessed in 287 adolescents with ADHD. The multiple regression analysis was used to examine the correlate of bullying victimization and perpetration. The prevalence rates of the pure victims, pure perpetrators, and victim-perpetrators were 14.6%, 8.4%, and 5.6%, respectively. Young age, a high BIS score, autism spectrum disorders, and low satisfaction with family relationships were associated with severe bullying victimization. A high score of fun seeking on the BAS and low satisfaction with family relationships were associated with severe bullying perpetration. A high proportion of adolescents with ADHD are involved in bullying. Multiple factors are associated with bullying involvement in adolescents with ADHD.

Based on the prior literature, we categorized participants as at risk for each of the three dopamine genes using this coding scheme: two 10-R alleles for DAT1; at least one A-1 allele for DRD2; at least one 7-R or 8-R allele for DRD4. Adolescent exposure to violence and school social environment was measured in 1994 and 1995 when participants were in high school or middle school. Intimate partner violence perpetration was measured in 2008 when participants were 24 to 32 years old. We used simple and multivariable logistic regression models, including interactions of genes and the adolescent environments for the analysis.Presence of risk alleles was not independently associated with IPV perpetration but increasing exposure to violence and disconnection from the school social environment was associated with physical IPV perpetration. The effects of these adolescent experiences on physical IPV perpetration varied by dopamine risk allele status. Among individuals with non-risk dopamine alleles, increased exposure to violence during adolescence and perception of disconnection from the school environment were significantly associated with increased odds of physical IPV perpetration, but individuals with high risk alleles, overall, did not experience the same increase.Our results suggested the effects of adolescent environment on adulthood physical IPV perpetration varied by genetic factors. This analysis did not find a direct link between risk alleles and violence, but

    Commonly used dating violence prevention programs assume that promotion of more egalitarian gender role attitudes will prevent dating violence perpetration. Empirical research examining this assumption, however, is limited and inconsistent. The current study examined the longitudinal association between gender role attitudes and physical dating violence perpetration among adolescent boys (n=577; 14% Black, 5% other race/ethnicity) and examined whether injunctive (i.e., acceptance of dating vi...

  6. Comprehensive Sexuality Education as a Primary Prevention Strategy for Sexual Violence Perpetration.

    Sexual violence (SV) represents a serious public health problem with high rates and numerous health consequences. Current primary prevention strategies to reduce SV perpetration have been shown to be largely ineffective-not surprisingly, since as others have pointed out current prevention largely fails to draw on existing knowledge about the characteristics of effective prevention. In this article, we examine the potential of K-12 comprehensive sexuality education (CSE), guided by the National Sexuality Education Standards (NSES), to be an effective strategy. Our discussion uses socioecological and feminist theories as a guide, examines the extent to which NSES-guided CSE could both meet the qualities of effective prevention programs and mitigate the risk factors that are most implicated in perpetration behavior, and considers the potential limitations of this approach. We suggest that sequential, K-12 program has potential to prevent the emergence of risk factors associated with SV perpetration by starting prevention early on in the life course. CSE has not yet been evaluated with SV perpetration behavior as an outcome, and this article synthesizes what is known about drivers of SV perpetration and the potential impacts of CSE to argue for the importance of future research in this area. The primary recommendation is for longitudinal research to examine the impact of CSE on SV perpetration as well as on other sexual and reproductive health outcomes.

    Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

    A substantial amount of research has revealed that cyberbully-victims have more emotional and behavioral problems than either cyberbullying victims or perpetrators. However, until now, little research has been conducted into the factors that contribute to the interplay between cyberbullying victimization and perpetration. The purpose of this study was to examine the relationship between cyberbullying victimization, perpetration, and two emotional components of alexithymia, namely difficulties in identifying and describing one's own feelings. Self-report questions were administered to 1549 adolescents between 12 and 18 years old ( M = 14.51; SD = 1.68; 42.1% ( n = 652) male) from Germany and Thailand. Results showed that cyberbullying victimization and alexithymia are associated with cyberbullying perpetration. Moreover, alexithymia mediated the associations between cyberbullying victimization and adolescents' cyberbullying perpetration. Consequently, we suggest that the ability to describe and identify one's own feelings might be important for understanding the link between cyberbullying, victimization, and perpetration. The results may help develop prevention and intervention programs focused on reducing cyberbullying.

    Attachment theory has increasingly been utilized to understand the etiology of sexual violence, and anxious attachment appears to be especially informative in this domain. We investigate the influence of general anxious attachment and specific anxious attachment on hostile masculine attitudes to predict male-perpetrated sexual assault. We hypothesize that hostile masculinity will mediate the relationship between general anxious attachment style and sexual assault perpetration (Hypothesis 1) and the relationship between specific anxious attachment to the assaulted woman and sexual assault perpetration (Hypothesis 2). Men ( N = 193) completed the Sexual Experiences Survey (SES) to determine sexual assault history and completed measures of general attachment style, specific attachment to the woman involved in the sexual activity, and measures of hostile masculine attitudes. Results support the hypothesized mediation models, such that general anxious attachment and specific anxious attachment are significantly associated with hostile masculinity, which in turn, predicts the likelihood of male-perpetrated sexual assault. The findings suggest that the unique characteristics of anxious attachment may escalate into hostile masculinity, which then increases the likelihood of sexual assault perpetration. This research is the first to investigate attachment bonds to the woman involved in the sexual activity and likelihood of sexual assault perpetration against the same woman.

    Although past findings show that insecure attachment and maladaptive personality traits confer risk for perpetrating intimate partner violence (IPV), little is known about how these factors may underpin psychological abuse (PA) committed in-person and via technology. This study examined whether borderline personality disorder (BPD) traits and psychopathic traits account for indirect effects of insecure attachment on the perpetration of face-to-face and cyber PA. Participants included a community-based sample ( N = 200; M age = 22.28 years) in Australia who completed a battery of online questionnaires. Results from bivariate correlations showed that elevated levels of attachment anxiety and avoidance, and higher scores on BPD traits and psychopathic traits, were significantly associated with the perpetration of both face-to-face and cyber PA. Findings from mediation analysis indicated that attachment anxiety was indirectly linked with the perpetration of both forms of PA via elevated scores on BPD traits and psychopathic traits. High levels of psychopathic traits accounted for the indirect effects of attachment avoidance on both forms of PA. Results support the theory that insecure attachment and maladaptive personality functioning might be involved in the development and/or maintenance of the perpetration of PA. These findings have implications for preventive and treatment programs for the perpetration of IPV in terms of shedding new light on potential risk factors for engagement in face-to-face and technology-based PA.

    Male perpetration of intimate partner violence (IPV) against women in Tanzania is widespread. Theory and empirical evidence suggest peer networks may play an important role in shaping IPV perpetration, although research on this topic in sub-Saharan Africa is limited. Grounded in social learning theory, social influence theory, and the theory of gender and power, the purpose of this study was to examine whether and how peer networks influence men's perpetration of IPV in Dar es Salaam, Tanzania. We conducted in-depth interviews (n = 40) with a sub-sample of 20 men enrolled in the control condition of an ongoing cluster-randomised controlled trial. We purposively sampled participants who previously reported perpetrating physical IPV. To analyse the data, we generated narrative summaries and conducted thematic and interpretative coding. We saw no evidence that men self-selected into peer networks with certain values or behaviours. Rather, men described several mechanisms through which their peers influenced the perpetration of IPV, including: (1) the internalisation of peer network norms, (2) pressure to conform to peer network norms and (3) the direct involvement of peers in shaping couple power dynamics. Our findings suggest that peer networks influence men's perpetration of IPV and should be targeted in future programmes and interventions.

    This study adopts a social-ecological/contextual perspective to explore Arab youth involvement in cyberbullying perpetration. We explored the association between individual (age, gender, and impulsivity), family (socioeconomic status and parental monitoring), and community (experiencing neighborhood violence) characteristics and cyberbullying perpetration. A moderation model exploring individual, family, and context interactions was tested. A sample of 3,178 Arab students in Grades 7 to 11 completed a structured, anonymous self-report questionnaire. The findings suggest that almost 14% of the participants have cyberbullied others during the last month. Adolescent boys with high impulsivity, low parental monitoring, and who experience a high level of violence in their neighborhood are at especially high risk of cyberbullying perpetration. Parental monitoring moderated the effects of impulsivity and experiencing neighborhood violence on adolescents' involvement in perpetrating cyberbullying. Furthermore, the results show that impulsive adolescents who experience high levels of neighborhood violence are at higher risk of cyberbullying perpetration than low impulsive children who experience the same levels of neighborhood violence. The results highlight the central role parenting plays in protecting their children from involvement in cyberbullying perpetration by buffering the effects of personal and situational risk factors.

A partir de documentos e bases de dados oficiais, faz-se uma análise do desenvolvimento dos sistemas de saúde e da organização da rede de serviços nesse segmento de fronteira localizado em plena região amazônica. Na comparação entre os três países, constata-se que o modelo adotado pelo Brasil tem as características de um sistema nacional de saúde de finalidade pública, enquanto na Colômbia e no Peru vigoram sistemas de asseguramento, com adoção de planos obrigatórios de assistência, segmentação dos usuários e contingenciamento da cobertura. Os três países convergem quanto à mescla de público e privado na provisão de serviços, mas diferem no nível de acesso e no tipo de regulação por parte do Estado. Conclui-se que as especificidades dos sistemas de saúde dos três países fronteiriços tornam complexo o desafio da construção de um sistema único de saúde na fronteira que possa garantir a universalidade do acesso, a equidade no atendimento e a integralidade da assistência. Apesar das discrepâncias identificadas, porém, constata-se que a preponderância do setor público na rede de atenção básica permite vislumbrar a possibilidade de integração dos sistemas locais de saúde no que concerne à oferta organizada de ações programáticas de saúde do primeiro e segundo níveis de assistência.The objectives of this article are to describe the health sector reform process in Latin American countries and its impact on the health systems of Brazil, Colombia, and Peru; analyze the structure of the

Given two arrays A, B of this type COMPAR has the capability to 1) re-norm A and B ind different ways; 2) calculate the deviations epsilon defined as epsilon(i,j,k,l): =[A(i,j,k,l) - B(i,j,k,l)] / GEW(i,j,k,l) where GEW (i,j,k,l) may be chosen in three different ways; 3) calculate mean, standard deviation and maximum in the array epsilon (by several intermediate stages); 4) determine traverses in the array epsilon; 5) plot these traverses by a printer; 6) simplify plots of these traverses by the PLOTEASY-system by creating input data blocks for this system. The main application of COMPAR is given (so far) by the comparison of two- and three-dimensional multigroup neutron flux-fields. (orig.) [de

    Hybrids between the indica and japonica subspecies of rice (Oryza sativa) are usually sterile, which hinders utilization of heterosis in the inter-subspecific hybrid breeding. The complex locus Sa comprises two adjacently located genes, SaF and SaM, which interact to cause abortion of pollen grains carrying the japonica allele in japonica-indica hybrids. Here we showed that silencing of SaF or SaM by RNA interference restored male fertility in indica-japonica hybrids with heterozygous Sa. We further used clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-based genome editing to knockout the SaF and SaM alleles, respectively, of an indica rice line to create hybrid-compatible lines. The resultant artificial neutral alleles did not affect pollen viability and other agricultural traits, but did break down the reproductive barrier in the hybrids. We found that some rice lines have natural neutral allele Sa-n, which was compatible with the typical japonica or indica Sa alleles in hybrids. Our results demonstrate that SaF and SaM are required for hybrid male sterility, but are not essential for pollen development. This study provides effective approaches for the generation of hybrid-compatible lines by knocking out the Sa locus or using the natural Sa-n allele to overcome hybrid male sterility in rice breeding.

    To investigate teen dating violence (TDV) perpetration (physical, sexual or psychological violence) and association with STI and related sexual risk behaviours among urban male adolescents. Adolescent male survey participants (N=134) were aged 14-20 years, recruited from urban health centres. Using crude and adjusted logistic regression, TDV perpetration was examined in relation to self-reported: STI, having sex with another person when they were only supposed to have sex with their main partner, and consistent condom use. Over one-third of males (45%) reported any TDV; 42% reported sexual violence perpetration, 13% reported perpetrating physical violence against a dating/sexual partner and 11% reported psychological violence, including threats of physical or sexual violence. Approximately 15% of males reported having ever had an STI, one quarter reported having sex with another person when they were only supposed to have sex with their main partner and 36% reported consistent condom use (past 3 months). In adjusted logistic regression models, TDV perpetration was significantly associated with self-reports of an STI (OR=3.3; 95% CI 1.2 to 9.2) and having sex with another person when they were supposed to be only having sex with their main partner (OR=4.8; 95% CI 2.0 to 11.4). There was no significant association between TDV perpetration and consistent condom use. Current study findings are the first within the literature on adolescents to suggest that greater STI and sexual risk behaviours among male adolescents perpetrating TDV may be one mechanism explaining increased STI among female adolescents reporting TDV victimisation.

    Mistreatment of medical students during medical education is a widespread concern. Studies have shown that medical students report the most mistreatment compared to students of other study programs and that the prevalence of mistreatment peaks during clinical training. For this reason, a study was conducted to assess prevalence of mistreatment among medical students committed by various groups of people. The focus was to identify whether gender was associated with the experience of mistreatment. Additionally, students' perception of university climate for reporting sexual harassment was assessed. In the study 88 medical students (45 women, 43 men) participated. A modified version of the Questionnaire on Student Abuse was used to assess students' experience of various types of mistreatment and associated distress during medical education. To explore factors that could be associated with this experience the organizational climate for reporting sexual harassment was assessed with the Psychological Climate for Sexual Harassment. The most often cited perpetrators of mistreatment were strangers (79.5%), friends (75.0%) and university staff (68.2%). Strangers mostly committed psychological mistreatment and sexual harassment, whereas friends additionally engaged in physical mistreatment of medical students. The most common form of mistreatment conducted by university staff was humiliation of students. These kinds of psychological mistreatment were reported to be distressing (43%). Gender differences were found in the prevalence of mistreatment. Women experienced more sexual harassment and humiliation than did men. On the other hand, men experienced more physical mistreatment than did women. Women reported experiencing more distress from mistreatment experiences than did men and also more often reported being mistreated by university staff than did men. Women perceived a greater risk in reporting sexual harassment to the organization than did men. Mistreatment of female and

    This study tested resource and feminist-informed theories to explain physical, sexual, psychological, and stalking intimate partner violence (IPV) perpetrated by court-mandated men. Data were obtained from 340 men arrested for physical assault of a partner before their court-ordered treatment. Using path analysis, findings provided partial support for each model. Ineffective arguing and substance-use problems were moderators of resources and perpetration. Dominance mediated early exposures and perpetration in the feminist-informed model. In both models, predictors of stalking were different than those for other types of perpetration. Future studies should replicate this research and determine the utility of combining models.

    Intimate partner violence (IPV) victims often report feeling confused and uninformed about court proceedings, including even about the final disposition of the case against their partner. This is problematic because victims' decisions in responding to subsequent abuse may be significantly influenced by their beliefs about the outcomes of prior court experiences. Also, researchers often rely on victim report of court case outcomes; discrepancies between women's reports and official records may account for some of the conflicting findings in the empirical literature. In the current study, we compared the reports of case outcome given by 81 women recruited immediately after the final hearing of an IPV-related criminal case against their perpetrator with court records of case outcome. Findings revealed a fair level of agreement between women's reports and court files that was significantly different from the level of agreement expected by chance, but far from perfect. Level of agreement increased substantially when cases involving suspended sentences were removed. In reviewing these findings, we discuss the extent to which results can or cannot be interpreted as reflecting the accuracy of women's knowledge and review their implications for IPV researchers and court systems.

    This study examines associations between maternal and paternal mental health and child bullying perpetration among school-age children, and whether having one or both parents with suboptimal mental health is associated with bullying. The 2007 National Survey of Children's Health, a nationally-representative, random-digit-dial survey, was analyzed, using a parent-reported bullying measure. Suboptimal mental health was defined as fair/poor (vs. good/very good/excellent) parental self-reported mental and emotional health. Of the 61,613 parents surveyed, more than half were parents of boys and were white, 20% were Latino, 15% African American, and 7% other race/ethnicity. Suboptimal maternal (OR 1.4; 95% CI 1.1-1.8) and paternal (OR 1.5; 95% CI 1.1-2.2) mental health are associated with bullying. Compared with children with no parents with suboptimal mental health, children with only one or both parents with suboptimal mental health have higher bullying odds. Addressing the mental health of both parents may prove beneficial in preventing bullying.

    The objective of this study was to examine the stability of physical and sexual intimate partner violence (IPV) perpetration from adolescence to emerging adulthood among sexual minorities. Adolescents who identified as a sexual minority (N = 135; 71.1% female; mean age = 15.02, standard deviation=.77; 34.1% African-American/black, 26.7% white, 22.2% Hispanic) from southeast Texas were assessed annually for 6 years on their IPV perpetration. Structural equation modeling demonstrated that physical IPV perpetration was modestly stable across years 1-4 (24.6%, 24.6%, 26.4%, and 21.6%, respectively), decreased in year 5 (18.6%), and increased in year 6 (24.5%). The stability of sexual IPV perpetration was high across all 6 years (14.3%, 13%, 14.9%, 10.8%, 12.4%, and 14.4%). This is the first study to examine the stability of IPV perpetration among sexual minority adolescents. Findings suggest that the development of interventions for IPV among sexual minority adolescents is needed, as IPV is unlikely to desist from adolescence to emerging adulthood.

    2012-11-01

    This study aims to contribute to the research field on cyberbullying by offering a comprehensive theoretical framework that helps to predict adolescents' perpetration of cyberbullying. One thousand forty-two pupils from 12 to 18 years old in 30 different Belgian secondary schools participated in two surveys within a three-month interval. Structural equation modeling was used to test whether the overall model of theory of planned behavior (TPB) helps to predict adolescents' self-reported perpetration in cyberbullying. Overall, the present study provides strong support for the theoretical utility of the TPB in cyberbullying research. The model accounted for 44.8% of the variance in adolescents' behavioral intention to cyberbully and 33.2% of the variance in self-reported cyberbullying perpetration. We found a strong positive relationship between adolescents' attitude towards cyberbullying and their behavioral intention to perpetrate it. Perceived behavioral control and subjective norm, the other two TPB-constructs, were also significant albeit relatively less important predictors of adolescents' intention to cyberbully. The finding that adolescents' attitude is the most important predictor of perpetration, entails that prevention and intervention strategies should aim at reducing the perceived acceptability of cyberbullying among adolescents by converting neutral or positive attitudes towards this anti-social behavior into negative evaluations.

    Theory and research suggest that an individual's negative interactions with his or her parents or romantic partner are associated with the perpetration of dating abuse. Research is beginning to explore the role of forgivingness within abusive romantic relationships, and these preliminary findings suggest that dispositional forgivingness might mediate the relations between negative interpersonal interactions and dating abuse. The current study assessed negative interactions with one's parents and one's romantic partner, the frequency of dating abuse perpetration, and dispositional forgivingness of others and oneself among a sample of emerging adults in college ( n = 421). Dispositional forgivingness of others was negatively associated with the perpetration of emotional/verbal dating abuse and threatening behaviors, and it mediated relations between negative interpersonal interactions and dating abuse perpetration. Our findings suggest that the tendency to forgive others may explain why some individuals who experience negative interpersonal interactions with parents or romantic partners do not escalate to perpetration of abuse within their romantic relationships. Implications for future research and application are discussed.

    This study examined associations between social-emotional intelligence (SEI) and two measures of violence perpetration (relational aggression and physical violence) in a cross-sectional sample of high-risk adolescent girls (N = 253). We evaluated three aspects of SEI: stress management, intrapersonal, and interpersonal skills. Results of a multiple linear regression model accounting for participants' age, race/ethnicity, and experiences of relational aggression victimization indicated that girls with better stress management skills were less likely to perpetrate relational aggression. A parallel model for perpetration of physical violence showed a similar pattern of results. Study findings suggest that SEI, and stress management skills in particular, may protect adolescent girls - including those who have been victims of violence - from perpetrating relational aggression and physical violence. Interventions that build adolescent girls' social and emotional skills may be an effective strategy for reducing their perpetration of violence.

    2018-01-01

    This article presents the first systematic review of family-only intimate partner violence (IPV) perpetrators (as originally proposed by Holtzworth-Munroe & Stuart). The aims of the present review were to summarize and describe the prevalence of the family-only perpetrator subtype, as well as to investigate what characteristics were associated with perpetrators within this subtype. Electronic literature searches in several databases (e.g., PsychINFO, Web of Science, and PubMed) were carried out. Of the 3,434 studies identified, 30 studies met the inclusion criteria as well as the methodological quality criteria. Thematic analyses were conducted, where several themes and subthemes were identified. The proportion of family-only perpetrators, averaged across sample types, was 47.5%. Drawing on the thematic analyses of the reviewed studies, family-only perpetrators presented as a less violent subtype, displaying several pro-social personality traits, as well as a lower degree of psychopathology. The findings were in line with Holtzworth-Munroe and Stuart's predictions. The findings also demonstrated the utility of a 2-fold typology, consisting of a family-only and a generally violent (GV) subtype, as well as the need to reconsider the one-size-fits-all approach to IPV treatment. We also included a discussion of the terminology of the subtypes and propose an adoption of the terms "partner only violent" and "generally violent" subtypes.

    Objectives. We examined associations between premigration political violence exposure and past-year intimate partner violence (IPV) perpetration among immigrant men attending community health centers in Boston. Methods. A convenience sample of immigrant men (N = 379; aged 18–35 years), largely from the Caribbean and Cape Verde, who attend community health centers, completed an anonymous, cross-sectional survey on risk and protective factors for male-perpetrated IPV and respondents’ exposure to political violence. Results. One in 5 (20.1%) immigrant men reported that they were exposed to political violence before arrival in the United States. Men reporting political violence exposure were significantly more likely to report IPV perpetration than were men not reporting such exposure (adjusted odds ratio [AOR] = 2.84; 95% confidence interval [CI] = 1.41, 5.74). Significant associations with political violence exposure were observed for both physical (AOR = 2.69; 95% CI = 1.11, 6.54) and sexual (AOR = 2.37; 95% CI = 1.04, 5.44) IPV perpetration. Conclusions. To our knowledge, our findings document for the first time the significant association between premigration political violence exposure and recent IPV perpetration among immigrant men. Additional work is needed to examine underlying mechanisms to inform culturally appropriate programs. PMID:18703450

    Commonly used dating violence prevention programs assume that promotion of more egalitarian gender role attitudes will prevent dating violence perpetration. Empirical research examining this assumption, however, is limited and inconsistent. The current study examined the longitudinal association between gender role attitudes and physical dating violence perpetration among adolescent boys (n = 577; 14 % Black, 5 % other race/ethnicity) and examined whether injunctive (i.e., acceptance of dating violence) and descriptive (i.e., beliefs about dating violence prevalence) normative beliefs moderated the association. As expected, the findings suggest that traditional gender role attitudes at T1 were associated with increased risk for dating violence perpetration 18 months later (T2) among boys who reported high, but not low, acceptance of dating violence (injunctive normative beliefs) at T1. Descriptive norms did not moderate the effect of gender role attitudes on dating violence perpetration. The results suggest that injunctive norms and gender role attitudes work synergistically to increase risk for dating violence perpetration among boys; as such, simultaneously targeting both of these constructs may be an effective prevention approach.

    Bullying and homophobic teasing behaviors affect the lives of many school aged children, often co-occur, and tend to peak in middle school. While bullying and homophobic teasing behaviors are known to be peer group phenomena, studies typically examine the associations at the individual or school levels. An examination of these behaviors at the peer group level can aid in our understanding of the formation and maintenance of peer groups that engage in these forms of aggressive behavior (selection), and the extent to which friends and the peer group impact individual rates of these aggressive behaviors (influence). In this longitudinal study, we assess the co-evolution of friendship networks, bullying perpetration, and homophobic teasing among middle school students (n = 190) using a Stochastic Actor-Based Model (SABM) for longitudinal networks. Data were collected from 6-8th-grade students (Baseline age 12-15; 53% Female; 47% Male) across three waves of data. The sample was diverse with 58% African American, 31% White, and 11% Hispanic. Since bullying and homophobic teasing behaviors are related yet distinct forms of peer aggression, to capture the unique and combined effects of these behaviors we ran models separately and then together in a competing model. Results indicated that on average individuals with higher rates of bullying perpetration and homophobic teasing were associated with becoming increasingly popular as a friend. However, the effects were not linear, and individuals with the highest rates of bullying perpetration and homophobic teasing were less likely to receive friendship nominations. There was no evidence that bullying perpetration or homophobic teasing were associated with the number of friendship nominations made. Further, there was a preference for individuals to form or maintain friendships with peers who engaged in similar rates of homophobic name-calling; however, this effect was not found for bullying perpetration.

    Studies show equal impact of sexual harassment (SH) on men and women, whereas lay perceptions are that women suffer more. We identify the phenomenon of minimization of male suffering (MMS), which occurs when people assume that SH has less effect on men's well-being and which results in the perpetrators of SH on men being evaluated less harshly. To verify whether these effects occur, we conducted two studies in which we presented stories describing acts of sexual coercion (SC, study 1) and SC or financial coercion (FC, study 2) and measured the perceived suffering of victims and the perception of the perpetrators. Both studies showed that female victims were perceived to suffer more from SC and FC and that perpetrators of both acts on women were evaluated more negatively. The results support our hypothesis that the suffering of male victims is minimized as they are perceived to suffer less than women.

    Cyberbullying perpetration (using communication technology to engage in bullying) is a recent phenomenon that has generated much concern. There are few prospective longitudinal studies of cyberbullying. The current article examines the individual, peer, family, and school risk factors for both cyber and traditional bullying (the latter is bullying that does not use technology) in adolescents. This article draws on a rich data set from the International Youth Development Study, a longitudinal study of students in Victoria, Australia and Washington State, United States, which began in 2002. In this article, data from almost 700 Victorian students recruited in grade 5 are analyzed to examine grade 7 (aged 12-13 years) predictors of traditional and cyberbullying perpetration in grade 9 (aged 14-15 years). Fifteen per cent of students engaged in cyberbullying, 21% in traditional bullying, and 7% in both. There are similarities and important differences in the predictors of cyber and traditional bullying. In the fully adjusted model, only prior engagement in relational aggression (a covert form of bullying, such as spreading rumors about another student) predicted cyberbullying perpetration. For traditional bullying, previous relational aggression was also predictive, as was having been a victim and perpetrator of traditional bullying, family conflict, and academic failure. The use of evidence-based bullying prevention programs is supported to reduce experiences of all forms of bullying perpetration (cyber, traditional, and relational aggression). In addition, for traditional bullying perpetration, addressing family conflict and student academic support are also important. Copyright © 2012 Society for Adolescent Health and Medicine.

    We report the strategy that we employed to identify the perpetrator of a suicide car bombing in front of the Australian Embassy in Jakarta, Indonesia, on 9 September 2004. The bomb was so massive that only small tissue pieces of the perpetrator could be recovered, preventing conventional approach to the identification of the bomber, necessitating the introduction of DNA analysis as the primary means for perpetrator identification. Crime scene investigation revealed the trajectory of the bomb blast, which was used to guide the collection of charred tissue fragments of the perpetrator. Mitochondrial DNA analysis was first conducted on 17 tissue fragments, recovered over large areas of the trajectory to, (a) confirm that they are of a common source, i.e. the perpetrator, and thus (b) establish the mtDNA HV1 sequence profile of the perpetrator. The mtDNA of the perpetrator matches that of a maternally related family member of one of four suspects. Standard autosomal STR analysis confirmed the identification. This case is of interest as an illustration of a successful application of DNA analysis as the primary means of disaster perpetrator identification.

    Full Text Available Introduction: Little is known about the risk and protective factors for youth sexual violence (SV perpetration across different types of relationships. This study examined factors associated with perpetrating SV against a dating partner and a same-sex peer.Methods: Analyses were based on data from a survey conducted in 2004 with public school boys and girls in grades 7, 9, 11, and 12 (N=4,131 in a high-risk, urban school district in the United States. SV perpetration was defined broadly to include forcing someone, about the same age and of the same or opposite sex as the respondent, to have sex or to do something sexual that they did not want to do. Analyses examined the associations between risk and protective factors and SV perpetration, adjusting for SV victimization and demographic characteristics.Results: Findings revealed that 2.1% of respondents reported perpetration against a same-sex peer and 3.2% reported perpetration against a date during the past 12 months. Victims of SV for each relationship type were more likely than non-victims to perpetrate SV. A combination of factors across the individual, relationship, and community level were significantly associated with SV perpetration and there were both shared and unique factors across the relationship types.Conclusion: Data suggest that programs to prevent SV perpetration for both relationship types should start when students are young, with particular focus on middle school boys. Prevention efforts should have slightly different foci to address these 2 types of SV perpetration. [West J Emerg Med. 2013;14(4:329–340.

  12. Comparing the Soviet and Chinese Famines: Their Perpetrators, Actors, and Victims

    Full Text Available The Soviet (1931-33 and Chinese (1958-62 famines were man-made catastrophes that occurred in underdeveloped states with growing populations during peacetime and affected traditional surplus areas. Both are marked by overly ambitious industrialization strategies at the expense of the rural economy in which central authorities failed to lower grain quotas once famine broke out and even increased them. The famines also had differences, notably regarding the nationality or ethnic question, which played a key role in Ukraine and was present in the Kazakh famine, but was absent in the Chinese famine. Also, Chinese Communist Party leaders, notwithstanding the cruelty of their policies, were much better disposed towards peasants than were the Soviet Bolsheviks. One cannot ascribe murderous intent on Mao’s part, but rather an incoherency of policy and unwillingness to recognize and correct his errors.

    With an estimated 2.5 million people living with HIV/AIDS, India has the third highest number of HIV-infected people in the world. Despite reductions in prevalence among the general population, the percentage of all infections occurring among Indian women is continuing to rise. Women s risk of HIV infection from their partner and observed associations between sexual violence and HIV infection in India underscore the importance of understanding determinants of forced sex. A probability survey was conducted from June 2003 to August 2007 in Chennai, India among alcohol venue (“wine shops”) patrons to estimate the prevalence of sexual violence and to identify risk factors associated with perpetrating forced sex. Among 1499 men, 28.5% reported forced sex with at least one partner in the past 3 months. In multivariate analysis, earning income for less than 12 months a year, visiting the wine shop with friends, STD symptoms, perpetration of physical violence, and number of sexual partners were statistically significantly associated with perpetrating forced sex. Men who reported having 3 or more close friends were less likely to perpetrate violence. HIV interventions that facilitate formal groups that foster positive social support and address a range of HIV risk behaviors including sexually and physically abusive behaviors are recommended to reduce sexual violence.

    2013-05-01

    Intimate partner violence is extremely common in college samples. To inform prevention and intervention efforts, understanding the motivation for engaging in partner aggression is critically important. The predominant view in the domestic violence field has been that women's use of intimate partner violence occurs in the context of self-defense. However, there has been a dearth of solid evidence to support this claim. The present study explored the motivations for the perpetration of minor and severe physical aggression and for three types of emotional abuse (restrictive engulfment, denigration, and dominance/intimidation) among college women. A detailed definition of self-defense was used and motivations for women who were sole perpetrators of physical violence as well as motivations for women who had been aggressed against in their romantic relationships were examined. Anger, retaliation for emotional hurt, to get partner's attention, jealousy, and stress were all common reasons for perpetrating partner violence among college women. Few women indicated that self-defense was a motive for their abusive behavior. The results suggest that prevention and intervention efforts to reduce partner violence perpetration by women should include anger and stress management.

    Although bullying has been widely recognized as a serious issue in elementary and secondary school and in the workplace, little is known about the prevalence of bullying in postsecondary education. We conducted a comprehensive search of the peer-reviewed literature and found 14 studies that reported the prevalence of bullying perpetration, victimization, or both in college or university students. Prevalence estimates varied widely been studies, but on average about 20-25% of students reported noncyberbullying victimization during college and 10-15% reported cyberbullying victimization. Similarly, approximately 20% of students on average reported perpetrating noncyberbullying during college, with about 5% reporting cyber perpetration. Men were more likely to report perpetration, but no consistent gender differences in victimization were found. Few studies reported prevalence by sexual orientation or race/ethnicity, and none reported prevalence by disability status. Overall, these results indicate that bullying continues to be prevalent in postsecondary education, but more research needs to be conducted, particularly that which uses multiuniversity samples and examines demographic differences in prevalence rates. © The Author(s) 2016.

    The literature on Multiple Perpetrator Rape (MPR) is scant; however, a significant proportion of sexual offending involves multiple perpetrators. In addition to the need for research with apprehended offenders of MPR, there is also a need to conduct research with members of the general public. Recent advances in the forensic literature have led to the development of self-report proclivity scales. These scales have enabled researchers to conduct evaluative studies sampling from members of the general public who may be perpetrators of sexual offenses and have remained undetected, or at highest risk of engaging in sexual offending. The current study describes the development and preliminary validation of the Multiple-Perpetrator Rape Interest Scale (M-PRIS), a vignette-based measure assessing community males' sexual arousal to MPR, behavioral propensity toward MPR and enjoyment of MPR. The findings show that the M-PRIS is a reliable measure of community males' sexual interest in MPR with high internal reliability and temporal stability. In a sample of university males we found that a large proportion (66%) did not emphatically reject an interest in MPR. We also found that rape-supportive cognitive distortions, antisocial attitudes, and high-risk sexual fantasies were predictors of sexual interest in MPR. We discuss these findings and the implications for further research employing proclivity measures referencing theory development and clinical practice.

    Gendered harassment, including sexual harassment and homophobic name-calling, is prevalent in adolescents and is linked to negative outcomes including depression, anxiety, suicidality, substance abuse, and personal distress. However, much of the extant literature is cross-sectional and rarely are perpetrators of these behaviors included in studies of outcomes. Therefore, the current study examined the effects of longitudinal changes in gendered harassment perpetration and victimization on changes in mental health outcomes among a large sample of early adolescents. Given that these behaviors commonly occur in the context of a patriarchal society (males hold power), we also investigated the impact of gender on gendered harassment. Participants included 3,549 students from four Midwestern middle schools (50.4% female, 49% African American, 34% White) at two time points (13 and 17 years old). Results indicated that increases from age 13 to 17 years in sexual harassment perpetration and victimization and homophobic name-calling perpetration and victimization predicted increases in depression symptoms and substance use. Gender did not moderate these pathways. These findings highlight that negative outcomes are associated with changes in gendered harassment among adolescents and emphasize the importance of prevention efforts. Implications for school interventions are discussed.

  7. The thrill of being violent as an antidote to posttraumatic stress disorder in Rwandese genocide perpetrators

    Directory of Open Access Journals (Sweden)

    2011-11-01

    Full Text Available 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.

    Landstedt, Evelina; Gillander Gådin, Katja

    2011-08-01

    To explore the psychological distress associations of experiences of several types of violence and the victim-perpetrator relationship of physical violence, a gender analysis was applied. Data were derived from a cross-sectional questionnaire study among 17-year-old upper secondary school students (N = 1,663). Variables in focus were: self-reported psychological distress, experiences of physical violence, sexual assault, bullying and sexual harassment. Logistic regressions were used to examine associations. Experiences of physical violence, sexual assault, bullying and sexual harassment were associated with psychological distress in boys and girls. The perpetrators of physical violence were predominately males. Whether the perpetrator was unknown or known to the victim seem to be linked to psychological distress. Victimisation by a boyfriend was strongly related to psychological distress among girls. Experiences of several types of violence should be highlighted as factors associated with mental health problems in adolescents. The victim-perpetrator relationships of violence are gendered and likely influence the psychological distress association. Gendered hierarchies and norms likely influence the extent to which adolescents experience violence and how they respond to it in terms of psychological distress.

    Hopeful future expectations have been linked to positive developmental outcomes in adolescence; however, the association between future expectations and bullying perpetration has received less attention. We examined the relationship between future expectations and physical and relational bullying perpetration and tested a mediation model that linked future expectations with bullying through attitude toward violence. Structural equation modeling was used to examine the relationship between future expectations and bullying perpetration (relational and physical) and to test whether these relationships were mediated by attitude toward violence in a sample of U.S. seventh-grade students (Mage = 12.86 years, N = 196, 60% female, 46% African American). Attitude toward violence fully mediated the relationship between future expectations and physical bullying (indirect effects = -0.08, 95% CI [-0.15, -0.01], R = .17). The relationship between future expectations and relational bullying was partially mediated by attitudes toward violence (indirect effects = -0.07, 95% CI [-0.14, -0.002], R = .20). Our findings suggest that future expectations can play a role in reducing attitude toward violence and physical and relational bullying perpetration among youth. Interventions that help support the development of future goals and aspirations could play a vital role in bullying prevention efforts.

    This study examined the associations of exposure to spousal violence in the family and personal and peer attitudes with dating violence (DV) perpetration among high school students in Port-au-Prince, Haiti. Participants were 342 high school students in Grades 10 to 12 who stated that they had ever been on a date. Multiple linear regression methods were used to examine correlates of the scale of DV perpetration. Findings showed that personal acceptance of DV mediated the association between exposure to wife-perpetrated and husband-perpetrated spousal violence in the family and DV perpetration for girls. Boys who were exposed to husband-perpetrated spousal violence in the family had significantly higher levels of psychological DV perpetration than those who were not. Contrary to expectations, exposure to wife-perpetrated spousal violence in the family was negatively associated with psychological and physical/sexual DV perpetration by boys, after controlling for other factors. Overall, perceived peer tolerance of DV was more strongly associated with DV perpetration than personal tolerance of DV, and was the only significant correlate of psychological DV perpetration for girls. Perceived peer attitudes also moderated the association between boys' exposure to spousal violence in the family and DV perpetration. Implications for future research and policy are discussed. © The Author(s) 2015.

    Violence among youth is a major public health issue globally. Despite these concerns, youth violence surveillance and prevention research are either scarce or non-existent, particularly in developing regions, such as sub-Saharan Africa. The purpose of this study is to quantitatively determine the prevalence of violence involving weapons in a convenience sample of service-seeking youth in Kampala. Moreover, the study will seek to determine the overlap between violence victimization and perpetration among these youth and the potentially shared risk factors for these experiences. We conducted this study of youth in May and June of 2011 to quantify and describe high-risk behaviors and exposures in a convenience sample (N=457) of urban youth, 14-24 years of age, living on the streets or in the slums and who were participating in a Uganda Youth Development Link drop-in center for disadvantaged street youth. We computed bivariate and multivariate logistic regression analyses to determine associations between psychosocial factors and violence victimization and perpetration. The overall prevalence of reporting violence victimization involving a weapon was 36%, and violence perpetration with a weapon was 19%. In terms of the overlap between victimization and perpetration, 16.6% of youth (11.6% of boys and 24.1% of girls) reported both. In multivariate analyses, parental neglect due to alcohol use (Adj.OR=2.28;95%CI: 1.12-4.62) and sadness (Adj.OR=4.36 ;95%CI: 1.81-10.53) were the statistically significant correlates of victimization only. Reporting hunger (Adj.OR=2.87 ;95%CI:1.30-6.33), any drunkenness (Adj.OR=2.35 ;95%CI:1.12-4.92) and any drug use (Adj.OR=3.02 ;95%CI:1.16-7.82) were significantly associated with both perpetration and victimization. The findings underscore the differential experiences associated with victimization and perpetration of violence involving weapons among these vulnerable youth.

    School bullying is the most common school violence among adolescents and has become a global concern. Little is known about the characteristics associated with bullies and victims among Jordanian students. The aim of the study was to examine student perceptions of school bullying-specifically, the characteristics of perpetrators and victims and how to stop bullying-and assess differences in perceptions between boys and girls. Cross-sectional study, using self-reported questionnaires, was employed to collect data from eighth-grade students (N = 913; 51% male) from a mixed rural and suburban area in northern of Jordan during the 2013-2014 school year. Descriptive statistics were used to summarize item responses. Chi-squared tests were performed to compare responses between the male and female students. Most of the students described a bully as one who is a coward underneath (78.9%), lacks respect for other people (70%), wants to show power (67.5%), wants to impress others (60.8%), and wants to feel superior (59.6%). Students perceived victims of bullying as having low self-esteem (68.2%), talking or sounding different than others (50.9%), shy (35%), and having no friends (27.1%). Students suggested that, to stop bullying, the victim should stand up for himself (75.4%), should become psychologically stronger (75.1%), and should involve adults (teachers, family, or others; 45.9%). There was a significant gender difference, in which boys and girls were describing victims and bullies differently. A significant percentage of students relate bullying and victimization characteristics to psychosocial characteristics and less to physical characteristics. The results offer valuable information necessary to design and implement school bullying prevention and intervention programs.

    Exposure to adult intimate partner violence (IPV) places youth at risk for a range of outcomes, including perpetration of adolescent dating violence (ADV). However, there is variability in the effect of IPV exposure, as many youth who are exposed to IPV do not go on to exhibit problems. Thus, research is needed to examine contextual factors, such as parenting practices, to more fully explain heterogeneity in outcomes and better predict ADV perpetration. The current research draws from a multisite study to investigate the predictive power of IPV exposure and parenting practices on subsequent ADV perpetration. Participants included 417 adolescents (48.7% female) drawn from middle schools in high-risk, urban communities. IPV exposure, two types of parenting practices (positive parenting/involvement and parental knowledge of their child's dating), and five types of ADV perpetration (threatening behaviors, verbal/emotional abuse, relational abuse, physical abuse, and sexual abuse) were assessed at baseline (2012) and approximately 5 months later (2013) via adolescent report. Analyses (conducted in 2015) used a structural equation modeling approach. Structural models indicated that IPV exposure was positively related only to relational abuse at follow-up. Further, adolescents who reported parents having less knowledge of dating partners were more likely to report perpetrating two types of ADV (physical and verbal/emotional abuse) at follow-up. Analyses did not demonstrate any significant interaction effects. Results fill a critical gap in understanding of important targets to prevent ADV in middle school and highlight the important role that parents may play in ADV prevention. Published by Elsevier Inc.

    Research with partner-violent men has found that a subset of this population reports dissociative experiences during their violence (e.g., inability to remember violence [despite admission that it had occurred]; flashbacks during violence). However, the literature examining this phenomenon has been primarily limited to clinical observations and case studies, and there is a need for more thorough empirical investigation regarding the prevalence and correlates of dissociative violence among individuals in intimate partner violence (IPV) intervention programs. The primary goals of this study were to provide descriptive information about the rates of endorsement of dissociative experiences during IPV perpetration and to examine their associations with trauma exposure and posttraumatic stress disorder (PTSD) symptoms. Participants were 302 men presenting for services at a community-based IPV intervention program. All variables were assessed via self-report and clinician interview at program intake. Results indicated that 22.2% of participants reported 1 or more dissociative experiences during partner violence perpetration. Additionally, frequency of dissociative IPV perpetration showed significant positive correlations with the total number of potentially traumatic events (PTEs) reported and PTSD symptoms, with effect sizes in the small and medium ranges of magnitude, respectively. Finally, PTSD symptoms significantly mediated the relationship between total number of PTEs and dissociative IPV perpetration. Findings indicate a potentially meaningful relationship between trauma, PTSD symptoms, and dissociative experiences during IPV perpetration. Further qualitative and quantitative investigation is needed to better understand this phenomenon and how it can be addressed in IPV treatment.

    The assessment of victims of child sexual abuse (CSA) is now a recognized aspect of clinical work for both CAMH and adult services. As juvenile perpetrators of CSA are responsible for a significant minority of the sexual assaults on other children, CAMH services are increasingly approached to assess these oversexualized younger children or sexually abusive adolescents. A developmental approach to assessment and treatment intervention is essential in all these cases. This review examines research on the characteristics of child victims and perpetrators of CSA. It describes evidence-based approaches to assessment and treatment of both groups of children. A selective review of MEDLINE, Psycinfo, Cochrane Library, and other databases was undertaken. Recommendations are made for clinical practice and future research. The characteristics of CSA victims are well known and those of juvenile perpetrators of sexual abuse are becoming recognized. Assessment approaches for both groups of children should be delivered within a safeguarding context where risk to victims is minimized. Risk assessment instruments should be used only as adjuncts to a full clinical assessment. Given high levels of psychiatric comorbidity, assessment, treatment, and other interventions should be undertaken by mental health trained staff. Victims and perpetrators of CSA present challenges and opportunities for professional intervention. Their complex presentations mean that their needs should be met by highly trained staff. However, their youth and developmental immaturity also give an opportunity to nip problem symptoms and behaviors in the bud. The key is in the earliest possible intervention with both groups. Future research should focus on long-term adult outcomes for both child victims and children who perpetrate CSA. Adult outcomes of treated children could identify problems and/or strengths in parenting the next generation and also the persistence and/or desistence of sexualized or abusive

    It has been suggested that child sexual abuse is related to poor attachment to parents, which is associated with an inability to form intimate relationships. Seto and Lalumière indicated that there were too few studies of adolescent males to determine whether poor attachment was associated with perpetration. This study was designed to follow up on a previous study and further explored the association between insecure attachment to parents, social isolation, and interpersonal adequacy to child sexual abuse perpetration in adolescents. We compared two samples of adolescent males who had committed sexual offenses, those who committed offenses against children (n = 140) and those who committed offenses against peer or adults (n = 92), with a sample of similarly aged males in treatment for mental health or substance use issues (n = 93). Data were collected using a semi-structured interview and computer-administered questionnaire. We found an indirect association between anxious attachment and sexual offenses against child victims, which was accounted for by measures of social involvement and social isolation. These involvement and isolation measures also did not have a direct association with sexual offenses against child victims, in that their contribution was accounted for by a measure of Masculine Adequacy. This Masculine Adequacy, combined with decreased levels of Sexual Preoccupation and Hypersexuality and increased Sexual Compulsivity, was associated with commission of child sexual abuse. The interpersonal variables did not enter a model predicting sexual offending against peers/adults, which seemed solely associated with the interaction between Sexual Compulsivity and Hypersexuality. © The Author(s) 2014.

    Children who are abused at home are at an increased risk of bullying perpetration and bullying victimization. Within that context, the purpose of the present study was to test Agnew's general strain theory and the peer deviancy training hypothesis by utilizing structural equation modeling to empirically examine pathways linking punitive parenting to bullying perpetration and bullying victimization. This study adds to the literature in two important ways. First, potential mediating linkages between punitive parenting and bullying perpetration and bullying victimization were examined, including socially withdrawn behavior and deviant peer affiliation. Second, these relationships were considered in a longitudinal sample of South Korean adolescents, which is a novel examination given that parenting in South Korea is guided largely by Confucianism which reinforces parental control, restrictiveness, and a punitive nature. Results indicate that: (1) punitive parenting is directly related to bullying perpetration but not bullying victimization; (2) punitive parenting was found to have indirect effects only on bullying perpetration; (3) deviant peer affiliation increased the likelihood of bullying perpetration and victimization; and (4) socially withdrawn behavior only affected bullying perpetration via its effect on deviant peer affiliation.

    Male perpetration of intimate partner violence (IPV) against women in sub-Saharan Africa is widespread. Theory and empirical evidence suggest peer networks may play an important role in shaping IPV perpetration, though research on this topic in the region is limited. We assessed the degree to which peer network gender norms are associated with Tanzanian men's perpetration of IPV and examined whether the social cohesion of peer networks moderates this relationship. Using baseline data from sexually active men (n = 1103) nested within 59 peer networks enrolled in an on-going cluster-randomized HIV and IPV prevention trial, we fit multilevel logistic regression models to examine peer network-level factors associated with past-year physical IPV perpetration. Peer network gender norms were significantly associated with men's risk of perpetrating IPV, even after adjusting for their own attitudes toward gender roles (OR = 1.53 , p =  . 04). Peer network social cohesion moderated this relationship (OR = 1.50 , p =  . 04); the positive relationship between increasingly inequitable (i.e., traditional) peer network gender norms and men's risk of perpetrating IPV became stronger, as peer network social cohesion increased. Characteristics of the peer network context are associated with men's IPV perpetration and should be targeted in future interventions. While many IPV prevention interventions focus on changing individual attitudes, our findings support a unique approach, focused on transforming the peer context.

    Studies have shown rates of IPV-perpetration among men in substance misuse treatment at rates far higher than the general population. There is poor evidence for the effectiveness of IPV perpetrator programmes. An analysis of drugs and alcohol policy documents 1998-2015 was conducted using discourse analysis to examine how English drug and alcohol policy has addressed IPV among substance misusers. Transcripts of interviews with 20 stake holders were analysed thematically. How policy 'frames' IPV-perpetration among drug and alcohol misusers has implications for service provision. IPV has increasingly been framed in terms of its implications for child safeguarding, and has been 'folded in' to policies targeting Troubled Families. With increasing 'localism' in English drug and alcohol policy there has been little specification of services for substance misusing IPV-perpetrators. Policy and literature produced by IPV perpetrator and victim organisations has framed IPV-perpetration as an individual choice with intoxication as a post hoc excuse for violence with limited implications for effective service development. Interviews with stake holders indicate a range of understandings/explanations for IPV among substance misusing men. Stake holders suggest that not all staff have the confidence or skills to ask men about their relationships and that there are few referral routes for substance misusing men who seek help for their IPV perpetration. There are gaps and contradictions in the extent to which English drug and alcohol policy has sought to address IPV-perpetration among substance misusers. Recent National Institute for Health and Care Excellence guidance provide an opportunity to include domestic abuse training for all front line social care staff including in the substance misuse sector. There is a need for further research into effective services for substance misusing perpetrators and the development of training for front-line staff. Copyright © 2016 The Authors

    Bullying prevalence studies are limited by varied measurement methods and a lack of representative samples. This study estimated the national prevalence of bullying victimisation, perpetration and combined victim-perpetration experiences in a representative population-based sample of Australian youth. The relationships between the three types of bullying involvement with a range of mental health symptoms and diagnoses were also examined. A randomly selected nationally representative sample aged 11-17 years ( N = 2967, M age = 14.6 years; 51.6% male) completed the youth component of the Second Australian Child and Adolescent Survey of Mental Health and Wellbeing (Young Minds Matter). Parents or carers also completed a structured face-to-face interview that asked questions about a single randomly selected child in the household. The youth survey comprised self-reported bullying victimisation and perpetration (Olweus Bully-Victim Questionnaire-adapted), psychological distress (K10), emotional and behavioural problems (Strengths and Difficulties Questionnaire), as well as self-harm, suicide attempts and substance use. Modules from the Diagnostic Interview Schedule for Children Version IV were administered to all youth and parents to assess for mental disorder diagnoses (major depressive disorder, any anxiety disorder and any externalising disorder [attention-deficit hyperactivity disorder, oppositional defiant disorder and conduct disorder]). The 12-month prevalence of bullying victimisation was 13.3%, perpetration 1.6% and victim-perpetration 1.9%. Logistic regression models showed all forms of involvement in bullying were associated with increased risk of psychological distress, emotional and behavioural problems, substance use, self-harm and attempted suicide. Victimisation and victim-perpetration were associated with youth-reported major depressive disorder. There were also significant associations between bullying involvement and parent-reported diagnoses of major

    Full Text Available From 1948 to 2007, the academic community produced about a hundred titles of theses and dissertations on drama and theater, or made use of data from drama and theater for larger spheres of studies. The current article looked into identifying trends and points of emphasis, as the researches and studies progressed through roughly half a century of research production in the academic setting. Inductive in approach and tentative and exploratory in its analysis, the study identified four trends and points of emphasis in research production. In the fifties and sixties, the emphasis was more on studying the play text or drama; studies veered towards a literary reading and orientation. Eventually, this trend gave way to studying the larger phenomenon of mounting, and the mise en scéne and the spectator became additional units of concern for research. Studies began to have sections on props, costumes, and staging techniques. In the eighties, a larger concern for looking at theater as social production followed. Participant observation, field work and ethnography gave equal emphasis on the social context of theater. Marxism and other perspectives from the social sciences framed theater studies then; correlations between theater and society became useful. Towards the last decade of the century, theater studies aimed at a more conceptual approach, emphasizing core concepts like panata and other related or equivalent terms, elevating and defining the study of theater as a study of culture itself.

    Full Text Available The paper devoted to the age and gender identity among the perpetrators of sexual violence against children and discussed the factors lead to pathogenesis of abnormal sexual behavior against children. We have identified particularities of gender and age identity in perpetrators of violent sexual acts against children. It was noted that patients with a diagnosis of pedophilia have abnormalities mostly in cognitive structure of sexual identity, that is shown in undifferentiated age peculiarities of perception of self-image and gender and role stereotypes. These data allow assessing more accurately the abnormalities of sexual sphere, explaining the deviant behavior, as well as structure of age and sex self-identity in persons with the disorder of sexual desire in the form of pedophilia and take a step closer to understanding the mechanisms of abnormal choice of sexual object.

    This article attempts to explain the motivations of perpetrators who committed violent acts in South Africa during the apartheid era. The relevant psychosocial literature is reviewed and the implicit and explicit explanations given during the amnesty hearings of the Truth and Reconciliation Committee by perpetrators working for the state security forces are analysed. The mental health of the South African society during this period is considered, as is the role of the former white South African government and its authorities in shaping the climate for a violent struggle involving all groups. The issues of individual versus social and state culpability, accountability, justice and reconciliation are explored and their implications for the future prevention of reoccurrences are assessed. The aim of the article is to prompt readers to ask the question: what are we capable of?

    This paper describes the extent to which abused and neglected children report intimate partner violence (IPV) victimization and perpetration when followed up into middle adulthood. Using data from a prospective cohort design study, children (ages 0-11) with documented histories of physical and sexual abuse and/or neglect (n=497) were matched with children without such histories (n=395) and assessed in adulthood (Mage=39.5). Prevalence, number, and variety of four types of IPV (psychological abuse, physical violence, sexual violence, and injury) were measured. Over 80% of both groups - childhood abuse and neglect (CAN) and controls - reported some form of IPV victimization during the past year (most commonly psychological abuse) and about 75% of both groups reported perpetration of IPV toward their partner. Controlling for age, sex, and race, overall CAN [adjusted odds ratio (AOR)=1.60, 95% CI [1.03, 2.49

    We examined blame attribution as a moderator of perceptions of hate crimes against gay, African American, and transgender victims. Participants were 510 Texas jury panel members. Results of vignette-based crime scenarios showed that victim blame displayed significant negative, and perpetrator blame significant positive, effects on sentencing recommendations. Also as hypothesized, victim and perpetrator blame moderated the effect of support for hate crime legislation. Interaction patterns suggested that both types of blame attribution influence sentencing recommendations, but only for participants disagreeing with hate crime legislation. Three-way interactions with victim type also emerged, indicating that the effects of both types of blame attribution show particular influences when the victim is gay, as opposed to transgender or African American. Implications for attribution theory, hate crime policy, and jury selection are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Perpetrators use rape supportive attitudes and sexual assault incident characteristics to justify forcing sex on their victims. Perpetrators who can justify their behaviors are at increased risk for future perpetration. This study examined the relationships between rape supportive attitudes, sexual assault incident characteristics, and the post-assault justifications of 183 men sampled from the community who self-reported committing at least one act of sexual aggression. Hierarchical multiple regression analyses indicated that rape supportive attitudes, expectations for having sex, misperceptions of sexual intent, victims’ alcohol consumption, attempts to be alone with her, and the number of consensual sexual activities prior to the unwanted sex were significant predictors of perpetrators’ post-assault use of justifications. Greater use of justifications was a significant predictor of sexual aggression over a 1-year follow-up interval. These findings demonstrate the need for further research exploring when and why perpetrators use post-assault justifications and whether they are amenable to change. PMID:26056162

    Background Violent trauma exposures, including child abuse, are risk factors for PTSD and comorbid mental health disorders. Child abuse experiences of men exacerbate adult male-perpetrated intimate partner violence (IPV). The relationship between child abuse, poor mental health and IPV perpetration is complex but research among the general population is lacking. This study describes the relationship and pathways between history of child abuse exposure and male-perpetrated IPV while exploring the potentially mediating effect of poor mental health. Methods We analysed data from a randomly selected, two-stage clustered, cross-sectional household survey conducted with 416 adult men in Gauteng Province of South Africa. We used multinomial regression modelling to identify associated factors and Structural Equation Modelling (SEM) to test the primary hypothesis that poor mental health (defined as abusing alcohol or having PTSD or depressive symptoms) mediates the relationship between child abuse and IPV perpetration. Results Eighty eight percent of men were physically abused, 55% were neglected, 63% were emotionally abused and 20% were sexually abused at least once in their childhood. Twenty four percent of men had PTSD symptoms, 24% had depressive symptoms and 36% binge drank. Fifty six percent of men physically abused and 31% sexually abused partners at least once in their lifetime. Twenty two percent of men had one episode and 40% had repeat episodes of IPV perpetration. PTSD symptomatology risk increased with severity of child trauma and other trauma. PTSD severity increased the risk for binge drinking. Child trauma, other trauma and PTSD symptomatology increased the severity of depressive symptoms. PTSD symptomatology was comorbid with alcohol abuse and depressive symptoms. Child trauma, having worked in the year before the survey, other trauma and PTSD increased the risk of repeat episodes of IPV perpetration. Highly equitable gender attitudes were protective

    This study investigates whether family and peer connections and prosocial norms buffer adolescent girls' violence involvement and whether a youth development intervention augments the power of these protective factors in reducing girls' risk for violence. Data were obtained from 253 13-17-year-olds enrolled in a randomized controlled trial of Prime Time, a youth development intervention offered through urban clinic settings to girls at high risk for pregnancy. Participants completed an audio computer-assisted self-interview survey at baseline and 6, 12, and 18 months after enrollment. Protective factors included scales assessing family and peer connections and prosocial norms. Outcome variables were violence victimization and perpetration scales measured at 18 months. Family connections and prosocial norms independently protected girls against violence involvement. Peer prosocial norms also served as a protective buffer against violence perpetration and victimization; however, girls with strong peer connections had higher levels of violence perpetration. Participation in Prime Time augmented the protective effects of family and peer connections on girls' violence victimization but not perpetration. Prime Time participants who had high levels of family connections reported the lowest levels of violence victimization at 18 months. Prime Time participants with strong peer connections trended toward lower levels of violence victimization than other girls. Results suggest that effects of the Prime Time intervention on violence victimization were optimized among high-risk adolescent girls with strong connections to family and peers. The intervention was most potent in preventing violence victimization among girls with strong prosocial connections to family and peers. Copyright © 2013 Society for Adolescent Health and Medicine.

Outcome variables were violence victimization and perpetration scales measured at 18 months. Results Family connections and prosocial norms independently protected girls against violence involvement. Peer prosocial norms also served as a protective buffer against violence perpetration and victimization; however, girls with strong peer connections had higher levels of violence perpetration. Participation in Prime Time augmented the protective effects of family and peer connections on girls’ violence victimization but not perpetration. Prime Time participants who had high levels of family connections reported the lowest levels of violence victimization at 18 months. Prime Time participants with strong peer connections trended toward lower levels of violence victimization than other girls. Conclusions Results suggest that effects of the Prime Time intervention on violence victimization were optimized among high-risk adolescent girls with strong connections to family and peers. The intervention was most potent in preventing violence victimization among girls with strong prosocial connections to family and peers. PMID:23299002

    Familicide is a multiple-victim homicide incident in which the killer's spouse and one or more children are slain. A systematic review was conducted to reveal the background factors of western homicide perpetrators. The systematic search was performed in the Arto, Medic, Cinahl, Medline, EBSCOhost Academic Search Premier and Social Services abstracts databases. The keywords were familicide, family homicide, familicide-suicide, filicide-suicide, extended suicide, child, murder, family, filicide and infanticide. The searches revealed 4139 references from the databases. The references were filtered and 32 peer-reviewed research articles revealed in years 2004-2014 were selected as data. The articles were analysed using inductive content analysis, by finding all possible background factors related to homicide. The factors were described as percentages of the range. The background factors of familicide perpetrators were categorised as follows: perpetrators who had committed homicide of a child and intimate partner and possibly committed suicide; a father had who killed a child; a mother who had killed a child; a father who had committed a filicide-suicide; and a mother who had committed a filicide-suicide. Psychological instability, violence and crime were found in all these categories of familicides. Perpetrators who had committed a suicide in addition to the familicide had more often been diagnosed with depression, but they sought treatment for mental health problems less often and had violence and self-destructiveness less often in their background than in other familicide categories. Social and healthcare professionals should be more sensitive to emerging family problems and be prepared for intervention.

    Little is known about the perpetrators of medical child abuse (MCA) which is often described as "Munchausen's syndrome by proxy" or "factitious disorder imposed on another". The demographic and clinical characteristics of these abusers have yet to be described in a sufficiently large sample. We aimed to address this issue through a systematic review of case reports and series in the professional literature. A systematic search for case reports and series published since 1965 was undertaken using MEDLINE, Web of Science and EMBASE. 4100 database records were screened. A supplementary search was then conducted using GoogleScholar and reference lists of eligible studies. Our search yielded a total sample of 796 perpetrators: 309 from case reports and 487 from case series. Information extracted included demographic and clinical characteristics, in addition to methods of abuse and case outcomes. Nearly all abusers were female (97.6%) and the victim's mother (95.6%). Most were married (75.8%). Mean caretaker age at the child's presentation was 27.6 years. Perpetrators were frequently reported to be in healthcare-related professions (45.6%), to have had obstetric complications (23.5%), or to have histories of childhood maltreatment (30%). The most common psychiatric diagnoses recorded were factitious disorder imposed on self (30.9%), personality disorder (18.6%), and depression (14.2%). From the largest analysis of MCA perpetrators to date, we provide several clinical recommendations. In particular, we urge clinicians to consider mothers with a personal history of childhood maltreatment, obstetric complications, and/or factitious disorder at heightened risk for MCA. Longitudinal studies are required to establish the true prognostic value of these factors as our method may have been vulnerable to publication bias. Copyright © 2017. Published by Elsevier Ltd.

    2017-01-01

    This study aimed to examine the pathways from child sexual abuse to sexual assault victimization and perpetration in adolescence and early adulthood, considering risky sexual behavior and lowered sexual self-esteem as mediator variables. In a two-wave longitudinal study with 2251 college students in Germany, male and female participants provided reports of sexual aggression victimization and perpetration since age 14 (T1) and again a year later (T2), covering the last 12 months. In addition, child sexual abuse (CSA; before the age of 14), risky sexual behavior, and sexual self-esteem were assessed at T1, and risky sexual behavior and sexual-self-esteem were assessed again at T2. Experience of CSA was significantly associated with greater likelihood of sexual aggression victimization and perpetration, lower sexual self-esteem, and more risky sexual behavior in both gender groups at T1 and was directly related to victimization at T2 among male participants. In both gender groups, CSA indirectly contributed to a higher probability of sexual victimization at T2 via its impact on victimization T1. In males, the indirect path from CSA to T2 perpetration via T1 perpetration was also significant. Through its negative impact on sexual self-esteem, CSA indirectly increased the probability of sexual victimization among women and the probability of sexual aggression perpetration among men. Risky sexual behavior mediated the pathway from CSA to sexual victimization at T2 for men and women and the pathway from CSA to sexual aggression perpetration for women. The findings contribute to the understanding of gendered effects of CSA on revictimization and the victim-to-perpetrator cycle. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study aims to examine the link between male perpetration of teen dating violence (TDV) and neighborhood violence, as well as associations with gender attitudes and perceived peer and neighborhood norms related to violence among a sample of urban adolescent boys. Participants of this cross-sectional study (N = 275) were between the ages of 14 and 20 years and recruited from urban community health centers. Crude and adjusted logistic and linear regression models were used to examine TDV perpetration in relation to (a) neighborhood violence involvement, (b) perceptions of peer violence, (c) perceptions of neighborhood violence, and (d) gender attitudes. Slightly more than one in four (28%) boys reported at least one form of TDV perpetration; among boys who have ever had sex, almost half (45%) reported at least one form of TDV perpetration. In logistic and linear regression models adjusted for demographics, boys who reported TDV perpetration were more likely to report involvement in neighborhood violence (odds ratio (OR) = 3.1; 95% confidence interval (CI) = 1.7-5.5), beliefs that their friends have perpetrated TDV (OR = 2.7; 95%CI = 1.4-5.1), perceptions of violent activity within their neighborhood (OR = 3.0; 95%CI = 1.4-6.3), and greater support of traditional gender norms (β = 3.2, p = 0.002). The findings suggest that efforts are needed to address boys' behaviors related to the perpetration of multiple forms of violence and require explicit efforts to reduce perceived norms of violence perpetration as well as problematic gender attitudes (e.g., increasing support for gender equity) across boys' life contexts.

    A large portion of persons who commit elder mistreatment have long been known to have indicators of substance abuse and/or mental health conditions (SAMHC). However, few studies have specifically examined elder mistreatment by persons with SAMHC, preventing the development of specialized intervention strategies. Using results from the National Elder Mistreatment Study, the current article examines victim, perpetrator, and interaction characteristics between cases of emotional and physical elder mistreatment in which the perpetrator is reported to have vs. not have SAMHC. Chi square tests and Mann-Whitney-Wilcoxon non-parametric tests were performed. 210 perpetrators of emotional elder mistreatment were reported to have SAMHC with 412 perpetrators of emotional mistreatment reported to not have SAMHC. 57 perpetrators of physical elder mistreatment were reported to have SAMHC with 38 perpetrators of physical mistreatment not having SAMHC. Emotional elder mistreatment committed by persons with SAMHC was associated with the following characteristics: perpetrator-unemployment, history of involvement with police, and fewer friendships; victim-female gender, greater emotional problems, and greater occurrences of lifetime emotional mistreatment; interaction-co-residence, and reporting of mistreatment to authorities. Physical elder mistreatment committed by persons with SAMHC was associated with police involvement of the perpetrator and greater occurrences of lifetime physical mistreatment experienced by the victim. These findings indicate that victims of elder mistreatment by persons with SAMHC are in particular need of intervention services as they have greater histories of mistreatment and experience greater emotional problems. Implications for effectively intervening in cases of elder mistreatment by persons with SAMHC are discussed.

    Watt, Margaret E; Scrandis, Debra A

    2013-09-01

    Despite efforts to use behavior modification interventions for male perpetrators, intimate partner violence (IPV) remains a significant problem in some male-female relationships. Childhood exposure to traumatic violent experiences, especially when untreated, can influence adult behaviors. Little is known about these possible factors in the lives of male perpetrators of IPV and if they influence their violent behavior against female intimate partners. This study's aim was to explore the life perspective of men who have been violent with their female intimate partners using Gadamer's hermeneutic phenomenology. Nine men with a history of female IPV were interviewed twice over a 5-month period. Interview content focused on their experiences in childhood and adult lives. Four themes emerged from the qualitative interviews: (a) childhood and family issues, (b) school and mental health issues, (c) substance abuse and (d) legal issues. Traumatic violent experiences in childhood, such as physical and sexual abuse, frequently led to school problems, misuse of substances, and arrests for a spectrum of crimes. These results highlight the importance of identifying traumatic violent exposures through a brief two-question screen of all children in primary care. Implications for individualized mental health treatment of male perpetrators and recommendations for further research are addressed.

  12. Predicting cyberbullying perpetration in emerging adults: A theoretical test of the Barlett Gentile Cyberbullying Model.

    Barlett, Christopher; Chamberlin, Kristina; Witkower, Zachary

    2017-04-01

    The Barlett and Gentile Cyberbullying Model (BGCM) is a learning-based theory that posits the importance of positive cyberbullying attitudes predicting subsequent cyberbullying perpetration. Furthermore, the tenants of the BGCM state that cyberbullying attitude are likely to form when the online aggressor believes that the online environment allows individuals of all physical sizes to harm others and they are perceived as anonymous. Past work has tested parts of the BGCM; no study has used longitudinal methods to examine this model fully. The current study (N = 161) employed a three-wave longitudinal design to test the BGCM. Participants (age range: 18-24) completed measures of the belief that physical strength is irrelevant online and anonymity perceptions at Wave 1, cyberbullying attitudes at Wave 2, and cyberbullying perpetration at Wave 3. Results showed strong support for the BGCM: anonymity perceptions and the belief that physical attributes are irrelevant online at Wave 1 predicted Wave 2 cyberbullying attitudes, which predicted subsequent Wave 3 cyberbullying perpetration. These results support the BGCM and are the first to show empirical support for this model. Aggr. Behav. 43:147-154, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The present study examined factors associated with the emergence and cessation of youth cyberbullying and victimization in Taiwan. A total of 2,315 students from 26 high schools were assessed in the 10th grade, with follow-up performed in the 11th grade. Self-administered questionnaires were collected in 2010 and 2011. Multiple logistic regression was conducted to examine the factors. Multivariate analysis results indicated that higher levels of risk factors (online game use, exposure to violence in media, internet risk behaviors, cyber/school bullying experiences) in the 10th grade coupled with an increase in risk factors from grades 10 to 11 could be used to predict the emergence of cyberbullying perpetration/victimization. In contrast, lower levels of risk factors in the 10th grade and higher levels of protective factors coupled with a decrease in risk factors predicted the cessation of cyberbullying perpetration/victimization. Online game use, exposure to violence in media, Internet risk behaviors, and cyber/school bullying experiences can be used to predict the emergence and cessation of youth cyberbullying perpetration and victimization.

    Multiple studies have demonstrated that adolescent dating violence is highly prevalent and associated with internalizing and externalizing problems. A number of prevention initiatives are being implemented in North-American high schools. Such initiatives do not only aim to raise awareness among potential victims and offenders but also among peer bystanders. Since teenagers mainly reach out to their peers when experiencing adversity, it is important to address adolescents' efficiency to deal with witnessing dating violence or with friends disclosing dating abuse, in addition to increasing ability to deal with experienced dating violence victimization or perpetration. The aim of this study is to explore adolescents' self-efficacy to deal with dating violence victimization and perpetration in their relationships and those of their peers. A paper-and-pencil questionnaire was completed by 259 14-18 years olds in Quebec, Canada. The data allows building insight into adolescents' confidence to reach out for help or to help others in a situation of dating violence victimization and perpetration. We also considered the impact of gender and dating victimization history. Results suggest that dating violence prevention can build on teens' self-efficacy to deal with dating violence and offer them tools to do so efficiently.

    This study examined the associations between maladaptive dependency-related schemas, posttraumatic stress disorder (PTSD) hyperarousal symptoms, and intimate-partner psychological and physical aggression in a sample of court-referred men (N = 174) participating in a domestic-abuser-intervention program. The men were largely African American; average age was 33.5 years. The extent to which hyperarousal symptoms moderated the association between dependency schemas and aggression was also examined. Maladaptive dependency-related schemas were positively associated with severe psychological, and mild and severe physical aggression perpetration. Hyperarousal symptoms were positively associated with mild and severe psychological aggression, and mild physical aggression perpetration. Multiple regression analyses showed a significant interaction for mild physical aggression: For those with high levels of hyperarousal symptoms, greater endorsement of maladaptive dependency schemas was associated with the perpetration of aggression (B = 0.98, p = .001). For those with low levels of hyperarousal symptoms, there was no association between dependency schemas and aggression (B = 0.04, ns). These findings suggest that focusing on problematic dependency and PTSD-hyperarousal symptoms in domestic-abuser-intervention programs may be helpful, and that examining related variables as possible moderators between dependency schemas and intimate aggression would be a fruitful area for future research.

    In terms of the intensive similarity between the sheet metal forming-springback process and that of the annealing of metals, it is suggested that the simulation of the sheet metal forming process is performed with the Nonlinear FEM and the springback prediction is implemented by solving the large-scale combinational optimum problem established on the base of the energy descending and balancing in deformed part. The BFGS-SA hybrid SA approach is proposed to solve this problem and improve the computing efficiency of the traditional SA and its capability of obtaining the global optimum solution. At the same time, the correlative annealing strategies for the SA algorithm are determined in here. By comparing the calculation results of sample part with those of experiment measurement at the specified sections, the rationality of the schedule of springback prediction used and the validity of the BFGS-SA algorithm proposed are verified

    Intimate partner violence directed at women by men continues to be a global concern. However, little is known about the factors associated with perpetrating intimate partner violence among heterosexual men. History of childhood sexual abuse and other sociodemographic variables were examined as potential factors associated with severe intimate partner violence perpetration toward women in a sample of heterosexual men in South Africa. Longitudinal logistic generalized estimating equations examined associations of childhood sexual abuse and sociodemographic variables at baseline with intimate partner violence perpetration at subsequent time points. Among participants with a steady female partner, 21.81 % (190/ 871) reported perpetrating intimate partner violence in the past year at baseline. Having a history of childhood sexual abuse (p sexual impulses in order to use a condom (p = .006) at baseline were associated with self-reported intimate partner violence perpetration in the past year at subsequent time points. With high levels of recent severe physical and/or sexual intimate partner violence perpetration in South Africa, comprehensive interventions are urgently needed. To more fully address gender-based violence, it is important to address associated factors, including exposure to childhood sexual abuse that could impact behavior later in life and that have long-lasting and deleterious effects on men and their female partners.

    Research suggests that the relationship between alcohol use and intimate partner violence (IPV) is moderated by a range of other factors. Therefore, we investigated the relationship between alcohol use, hostile sexism, and religious self-regulation with perpetration. Using a national sample of 255 men, we found that hostile sexism was associated with physical violence toward a partner and alcohol use was positively associated with psychological abuse toward a partner. With regard to religious self-regulation, we found that introjected religious self-regulation was positively associated with hostile sexism and positively associated with perpetrating physical IPV. Identified religious self-regulation was negatively associated with physical violence perpetration. We also found significant interactions among our independent measures on physical IPV perpetration. These analyses suggest that increased alcohol consumption elevates the risk for physical violence perpetration among men who are high in introjected religious self-regulation and low in hostile sexism, while reducing the risk for perpetration in men who are high in identified religious self-regulation and low in hostile sexism. Implications and limitations of the findings are discussed.

This study examined correlates of client-perpetrated sexual, physical, and economic violence (e.g., robbery against FSWs in 13 cities throughout Mexico.FSWs (N = 1,089 who were enrolled in a brief, evidence-based, sexual risk reduction intervention for FSWs (Mujer Segura were interviewed about their work context, including experiences of violence perpetrated by clients, sexual risk and substance use practices, financial need, and social supports. Three broad categories of factors (sociodemographic, work context, behavioral and social characteristics of FSWs were examined as correlates of sexual, physical, and economic violence.The prevalence of different types of client-perpetrated violence against FSWs in the past 6 months was: sexual (11.7%, physical (11.8%, economic (16.9%, and any violence (22.6%. Greater financial need, self-identification as a street worker, and lower perceived emotional support were independently associated with all three types of violence. Alcohol use before or during sex with clients in the past month was associated with physical and sexual violence. Using drugs before or during sex with clients, injection drug use in the past month, and population size of city were associated with sexual violence only, and FSWs' alcohol use score (AUDIT-C was associated with economic violence only.Correlates of client-perpetrated violence encompassed sociodemographic, work context, and behavioral and social factors, suggesting that approaches to violence prevention for FSWs must be multi-dimensional. Prevention could involve teaching FSWs strategies for risk avoidance in the workplace (e.g., avoiding use of alcohol with clients, enhancement of FSWs' community-based supports, development of interventions that deliver an anti

    APROS SA is a severe accident training simulator based on the APROS simulation environment. APROS SA has been developed in Fortum Nuclear Services Ltd to serve as a training tool for the personnel of the Loviisa NPP. Training with APROS SA gives the personnel a deeper understanding of the severe accident phenomena and thus it is an important part of the implementation of the severe accident management strategy. APROS SA consists of two parts, a comprehensive Loviisa plant model and an external severe accident model. The external model is an extension to the Loviisa plant model, which allows the simulation to proceed into the severe accident phase. The severe accident model has three submodels: the core melting and relocation model, corium pool model and fission product model. In addition to these, a new thermal-hydraulic solver is introduced to the core region of the Loviisa plant model to replace the more limited APROS thermal-hydraulic solver. The full APROS SA training simulator has a graphical user interface with visualizations of both severe accident management panels at the operator room and the important physical phenomena during the accident. This paper describes the background of the APROS SA training simulator, the severe accident submodels and the graphical user interface. A short description how APROS SA will be used as a training tool at the Loviisa NPP is also given

This study scrutinizes factors associated with mental health among women victims and perpetrators of IPV over the 12 months prior to the study.Methods and materials: Mental health data were analyzed with bivariate and multiple regression methods for 1442 women aged 15–49 years who contacted Forensic Services at Maputo Central Hospital (Maputo City, Mozambique for IPV victimization between April 1, 2007 and March 31, 2008.Results: In bivariate analyses, victims and perpetrators of IPVs scored higher on symptoms of mental health than their unaffected counterparts. Multiple regressions revealed that controlling behaviors, mental health comorbidity, social support, smoking, childhood abuse, sleep difficulties, age, and lack of education were more important in explaining symptoms of mental health than demographics/socioeconomics or life-style factors. Victimization and perpetration across all types of IPV were not associated with symptoms of mental health.Conclusion: In our sample, victimization and perpetration were not important factors in explaining mental ill health, contrary to previous findings.

    Emerging research suggests significant positive associations between bullying and substance use behaviors. However, these studies typically focused either on the link between substance use and bullying perpetration or victimization, and few have conceptualized bullying perpetration and/or victimization as mediators. In this study, we simultaneously tested past bullying perpetration and victimization as mediational pathways from retrospective report of parenting styles and global self-esteem t...

    There has been very little prospective research on rape perpetration among men. This paper describes the incidence and risk factors for new rape and attempted rape events among young South African men in an HIV prevention trial. We followed 1,147 men aged 15-26 years who enrolled into a cluster randomised controlled trial to evaluate the HIV prevention behavioural intervention Stepping Stones. Incidence rate ratios for factors associated with incident rape were derived from Poisson models. The young men reported 217 incident rapes (completed or attempted) of a girl or woman over 1,914 person years of follow up, yielding a rape incidence of 11.2 per 100 person years. Overall 24.9% of men had previously raped at baseline, and 18.9% did so during the follow up. Among the latter, 61.3% raped for the first time, and 38.7% re-offended. Multivariable Poisson modelling showed a higher incidence of rape perpetration among men who had ever used drugs (IRR 1.86 95%CI 1.39, 2.49), had eight or more lifetime partners (IRR 1.48 95% CI 1.09, 2.01), had been physically violent toward a female partner (IRR 1.50 95%CI 1.11, 2.03) and had disclosed rape perpetration at baseline (IRR 1.45 95%CI 1.07, 1.97). A lower incidence was found among those with greater resistance to peer pressure (IRR 0.85 95%CI 0.74, 0.97). The findings highlight the importance of male gender socialisation and addressing delinquent youth sub-cultures in rape prevention. Prevention requires change in hegemonic masculinity, with its emphasis on gender hierarchy, exaggerated performance of heterosexuality and control of women. Interventions are needed to address male socialisation with delinquent peers, by reducing exposure to childhood trauma and strengthening opportunities for gainful employment (in work or recreation).

    Neighborhood context plays a role in the development of adolescent health risk behaviors, but few studies have investigated the influence of neighborhoods on the perpetration of dating violence. This longitudinal study examined the direct effects of risky neighborhood structural and physical characteristics on trajectories of the perpetration of dating violence, tested whether collective efficacy mediated these relationships, and determined if the effects varied by the sex of the adolescent. Adolescent data are from a multi-wave longitudinal study from grades 8 to 12; neighborhood data were collected from parents' interviews and U.S. Census data. Multilevel growth curve models were conducted with 3,218 students; the sample was 50% male, 41% White, 50% Black, and 9% other race/ethnicity. In models examining risky neighborhood variables one at a time, and controlling for potential individual-level confounders, the sex of the adolescent interacted with economic disadvantage, residential instability, and physical disorder; these risky neighborhood characteristics increased risk for girls' but not boys' perpetrating of dating violence. In full models with all of the risky neighborhood variables, the sex of the adolescent continued to interact with neighborhood economic disadvantage; living in economically disadvantaged neighborhoods increased girls' but not boys' risk for dating violence across all ages. No other risky neighborhood effects were found for boys or girls. Collective efficacy did not mediate the relationships between other neighborhood characteristics and the outcome. These findings suggest that dating violence prevention strategies for girls should consider the contexts in which they live rather than only targeting changes in their individual characteristics.

    Little is known about the role social support may play in reducing the risk of adolescent dating violence perpetration and victimization. This study is a longitudinal analysis of the independent impact of social support from friends and parents on the risk of emotional and physical dating violence perpetration and victimization among a large sample of female youth (n = 346). Findings indicate that 22% of the sample indicated perpetrating physical dating violence against a partner, whereas almost 16% revealed being the victim of physical dating violence; 34% of the sample indicated perpetrating emotional dating violence against a partner, whereas almost 39% revealed being the victim of emotional dating violence. Negative binomial regression models indicated that increased levels of support from friends at Time 1 was associated with significantly less physical and emotional dating violence perpetration and emotional (but not physical) dating violence victimization at Time 2. Parental support was not significantly related to dating violence in any model. Implications for dating violence curriculum and future research are addressed.

  18. Empathy Impairments in Intimate Partner Violence Perpetrators With Antisocial and Borderline Traits: A Key Factor in the Risk of Recidivism.

    2016-01-01

    Antisocial, borderline, and narcissistic personality traits have been described as characteristics of intimate partner violence (IPV) perpetrators. Furthermore, deficits in cognitive empathy and impairments in emotional decoding processes may at least partially explain conduct disorders and social dysfunction in general. However, previous research has not explored potential associations between empathy deficits and the aforementioned traits or whether they are reflected in recidivism in IPV perpetrators. Accordingly, the main aim of this study was to explore associations between empathy deficits, antisocial, borderline, and narcissistic traits and the risk of recidivism in this population. The sample consisted of 144 IPV perpetrators (mean age = 41 years). High antisocial and borderline personality traits in this sample were associated with a high risk of recidivism, these relationships being moderated by poor empathy skills. Moreover, in IPV perpetrators with both antisocial and borderline personality traits, the risk of recidivism was higher than in those with only one of these traits. In contrast, narcissistic traits were unrelated to the risk of recidivism and impairments in empathy. The results of our study highlight the importance of empathy deficits and may help professionals to develop specific intervention programs focusing on improving empathy skills in antisocial and borderline IPV perpetrators.

    The current study is concerned with the different types of gender stereotypes that participants may draw upon when exposed to news stories about intimate partner violence (IPV). We qualitatively analyzed open-ended responses examining four types of gender stereotypes-aggression, emotional, power and control, and acceptability of violence. We offer theoretical implications that extend past research on intimate terrorism and situational couple violence, the gender symmetry debate, and how stereotypes are formed. We also discuss practical implications for journalists who write stories about IPV and individuals who provide services to victims and perpetrators. © The Author(s) 2016.

  2. An examination of the factors related to dating violence perpetration among young men and women and associated theoretical explanations: a review of the literature.

    2015-04-01

    This article provides a review of the literature on dating violence (DV) perpetration, specifically sex similarities and differences in the correlates and predictors of DV perpetration and the utility of current theories to explain young men's and women's DV perpetration. Overall, many of the correlates and predictors of DV perpetration are similar among young men and women (e.g., witnessing interparental violence, experiencing child abuse, alcohol abuse, traditional gender roles, relationship power dynamics). However, young women's perpetration of DV is more strongly related to internalizing symptoms (e.g., depression), trait anger and hostility, and experiencing DV victimization than young men's perpetration, whereas young men's perpetration of DV is more consistently related to lower socioeconomic status and educational attainment, antisocial personality characteristics, and increased relationship length than young women's perpetration. Each theory offers insights into but does not fully account for the correlates and predictors of DV perpetration. Sociocultural theories may be useful in explaining the use of coercive control in relationships, and learning/intergenerational transmission of violence theories may be useful in explaining bidirectional couple violence. Future research should focus on integrative theories, such as in the social-ecological theory, in order to explain various forms of DV. Our understanding of young men's and young women's DV perpetration is limited by cross-sectional research designs, methodological inconsistencies, a lack of sex-specific analytic approaches, and a lack of focus on contextual factors; more multivariate and longitudinal studies are needed. Further, as DV prevention programming is often presented in mixed-sex formats, a critical understanding of sex differences and similarities in DV perpetration could ultimately refine and improve effectiveness of programming efforts aimed at reducing DV. © The Author(s) 2014.

    2016-02-01

    Previous research has suggested that social anxiety is associated with victimization and perpetration of (cyber)bullying. The direction and causality of this relationship has not yet been empirically supported for both traditional and cyberbullying involvement. This study examined short-term longitudinal associations between feelings of social anxiety and involvement in traditional bullying and cyberbullying among 2128 adolescents aged 10-17 (56.6 % girls). A cross-lagged panel analysis provided evidence for the contribution of social anxiety to later victimization of bullying, both on- and off-line. The possibility of a reciprocal relationship was also examined, although it was not supported. Furthermore, longitudinal bidirectional relationships between social anxiety and the perpetration of bullying were investigated. Only one significant longitudinal association was found: the perpetration of traditional bullying predicted subsequent higher levels of social anxiety. The implications of these findings are discussed.

    School-based bullying perpetration and victimization is common worldwide and has profound impacts on student behavior and mental health. However, few studies have examined young adult outcomes of bullying perpetration or victimization. Research on factors that protect students who have bullied or been bullied is also lacking. This study examined young adult externalizing and internalizing problems (aged 18-19 years) and adolescent protective factors related to self-reported bullying perpetration and victimization among over 650 Victorians aged 16-17 years. Opportunities for prosocial involvement in the family lessened subsequent involvement in nonviolent antisocial behavior, as an outcome of prior bullying. High academic performance and having strategies to cope with stress reduced young adult depressive symptoms for participants who had been victims of bullying. The implications for bullying prevention and early intervention programs are discussed.

    Research on women's perpetration of physical violence has focused primarily on partners, often neglecting perpetration against nonpartners. This study proposes a conceptual model with direct and indirect relationships between childhood adversity and different targets of violence (partners and nonpartners), mediated by victimization experiences (by partner and nonpartners), mental illness, substance abuse, and anger. Using survey data from a random sample of incarcerated women (N = 574), structural equation modeling resulted in significant, albeit different, indirect paths from childhood adversity, through victimization, to perpetration of violence against partners (β = .20) and nonpartners (β = .19). The results indicate that prevention of women's violence requires attention to specific forms of victimization, anger expression, and targets of her aggression.

    Ibrutinib (PCI-32765), a potent covalent inhibitor of Bruton's tyrosine kinase, has shown efficacy against a variety of B-cell malignancies. Given the prominent role of CYP3A in ibrutinib metabolism, effect of coadministration of CYP3A perpetrators with ibrutinib was evaluated in healthy adults. Ibrutinib (120 mg [Study 1, fasted], 560 mg [studies 2 (fasted), and 3 (nonfasted)]) was given alone and with ketoconazole [Study 1; 400 mg q.d.], rifampin [Study 2; 600 mg q.d.], and grapefruit juice [GFJ, Study 3]. Lower doses of ibrutinib were used together with CYP3A inhibitors [Study 1: 40 mg; Study 3: 140 mg], as safety precaution. Under fasted condition, ketoconazole increased ibrutinib dose-normalized (DN) exposure [DN-AUClast: 24-fold; DN-C max: 29-fold], rifampin decreased ibrutinib exposure [C max: 13-fold; AUClast: 10-fold]. Under nonfasted condition, GFJ caused a moderate increase [DN-C max: 3.5-fold; DN-AUC: 2.2-fold], most likely through inhibition of intestinal CYP3A. Half-life was not affected by CYP perpetrators indicating the interaction was mainly on first-pass extraction. All treatments were well-tolerated.

    2016-01-01

    Full Text Available The aim of this paper is to map out - by analysing the film Son of Saul, but also by its comparison with two other films dealing with the topic, Himmelkommando and The Grey Zone, the narrative mechanism that satisfies the complex ethical and aesthetical demands imposed by the theme of Sonderkommando as the particular episode of the Holocaust. The key element of the narrative structure is the construction of the Levi’s “dead and drowned” witness who “resurrected” through the narrative intervention becomes the only reliable and credible narrator of the historical trauma. The prerequisite for his emergence is the narration and representation of the death which makes but also solves the traumatised - understood as multiple, fragmented, opposed - identities of the members of the special squad. Their entangled identity involves the simultaneous presence of a victim, perpetrator, witness and the authentic narrator of the trauma of the death camp. The death of the perpetrator is the condition sina qua non for the emergence of the figure of the victim-witness narrator but also for making of narrative which overcomes the initial trauma of the Holocaust. The detailed analysis of the film Son of Saul confirms and identifies these narratives as the modernist narration of the post-traumatic film.

    Intimate partner violence (IPV) affects more than 12 million individuals annually. Power and control are central concepts underlying abusive relationships. Physicians may see IPV victims, perpetrators, and their children for annual examinations, as well as for injuries and health conditions associated with abuse. In 2013, the US Preventive Services Task Force recommended that women of childbearing age (ie, 14 to 46 years) be screened for IPV. Brief, validated screening tools, such as the 4-item Hurt, Insult, Threaten, and Scream (HITS), can be used to facilitate screening. Physicians should always assess patients whose medical histories or presenting symptoms or injuries are consistent with abuse. Risk factors for IPV and consequences of abuse include general health conditions (eg, asthma, irritable bowel syndrome), reproductive issues (eg, gynecologic disorders, unintended pregnancies), psychological conditions (eg, depression, sleep disturbances), and risky health behaviors (eg, substance use, poor health care adherence). Tools for identifying perpetrators are under investigation. To prepare the practice to address IPV, physicians should educate themselves and staff and learn about community and national resources. By identifying and responding to IPV, clinicians may be able to reduce IPV and interrupt the intergenerational cycle of violence.

    This review examines the association between alcohol and illicit drug use and the perpetration of intimate partner violence (IPV) and child maltreatment (CM). In clinical populations, alcohol use is related to IPV, although other variables are also known to influence this relationship. Studies in specialized social/health care and in the community have also demonstrated the association between alcohol use and IPV. Although data on the association between illicit drug use and IPV are less clear, in most studies perpetration seems related to the use of cannabis and cocaine. The occurrence of CM is related to alcohol use in specialized social/health care and community populations but has not been extensively investigated in clinical samples. These findings also apply to studies on the association between illicit drug use and CM. Moreover, many studies on CM fail to distinguish between the effects of alcohol and those of illicit drugs. This review concludes with recommendations for future research about substance use and family violence and discusses implications for prevention and treatment. © The Author(s) 2015.

    2012-08-01

    We examined the hypothesis that family, peer and neighborhood violence would moderate relations between heavy alcohol use and adolescent dating violence perpetration such that relations would be stronger for teens in violent contexts. Random coefficients growth models were used to examine the main and interaction effects of heavy alcohol use and four measures of violence (family violence, friend dating violence, friend peer violence and neighborhood violence) on levels of physical dating violence perpetration across grades 8 through 12. The effects of heavy alcohol use on dating violence tended to diminish over time and were stronger in the spring than in the fall semesters. Consistent with hypotheses, across all grades, relations between heavy alcohol use and dating violence were stronger for teens exposed to higher levels of family violence and friend dating violence. However, neither friend peer violence nor neighborhood violence moderated relations between alcohol use and dating violence. Taken together, findings suggest that as adolescents grow older, individual and contextual moderators may play an increasingly important role in explaining individual differences in relations between alcohol use and dating violence. Implications for the design and evaluation of dating abuse prevention programs are discussed.

  12. Individual and Family Predictors of the Perpetration of Dating Violence and Victimization in Late Adolescence

    2012-01-01

    Teen dating violence is a crime of national concern with approximately one-fourth of adolescents reporting victimization of physical, psychological, or sexual dating violence each year. The present study examined how aggressive family dynamics in both childhood and early adolescence predicted the perpetration of dating violence and victimization in late adolescence. Children (n=401, 43% female) were followed from kindergarten entry to the age of 18 years. Early adolescent aggressive-oppositional problems at home and aggressive-oppositional problems at school each made unique predictions to the emergence of dating violence in late adolescence. The results suggest that aggressive family dynamics during childhood and early adolescence influence the development of dating violence primarily by fostering a child’s oppositional-aggressive responding style initially in the home, which is then generalized to other contexts. Although this study is limited by weaknesses detailed in the discussion, the contribution of longitudinal evidence including parent, teacher, and adolescent reports from both boys and girls, a dual-emphasis on the prediction of perpetration and victimization, as well as an analysis of both relations between variables and person-oriented group comparisons combine to make a unique contribution to the growing literature on adolescent partner violence.

    2015-01-01

    Full Text Available Restorative justice as the theoretical foundation of social reaction to crime is one of the key themes of contemporary criminological discourse. The idea of crime as a conflict between perpetrator and victim of crime is included in the core ideas related to the concept of restorative justice, which differs from traditional understanding of crime as a relationship between the state and the individual. This change in perspective on crime points towards social reaction to crime that differs from traditional criminal justice system. As the restoration process of relationship damaged by crime is directly related to possibilities of participation in the very process, institutionalisation of that participation sets the scope of restorative process. In this article, the author points towards the traditional criminal justice and restorative justice processes, focusing the relationship of perpetrator and victim of crime and the process of conflict resolution. The aim of the article is to highlight the conflict perspective as a defining element of the relationship between offender and victim, and to underline the effectiveness of restorative justice as social reaction to crime, which contributes to optimisation of the relationship between the offender and the community.

    The present study analyzed relationship of workplace violence and perpetrators of violence on sleep disturbance among wage workers in Korea. The present study used data from the 4th Korean Working Conditions Survey (KWCS) of 2014 in selecting a total of 25,138wage workers as the study population, which excluded those who failed or refused to respond to questions required for the present study. The workplace violence experience group included people who satisfied at least one of six relevant criteria (verbal abuse, unwanted sexual attention, threatening or humiliating behavior, physical violence, bullying/harassment, and sexual harassment) and the group was divided according to whether the perpetrator of violence was a client or colleague. Presence of sleep disturbance was determined based on subjective symptoms felt within the past 12 months by each individual. A multiple logistic regression analysis was performed to identify the effects on sleep distance according to general, occupational, and psychosocial characteristics, as well as the types of workplace violence and perpetrators of violence. Workplace violence was found as a factor affecting sleep disturbance (OR = 3.773, 95 % CI = 3.058-4.655), and with respect to perpetrators of violence, complaint of sleep disturbance symptoms was higher when the perpetrator was a colleague or boss (OR = 5.688, 95 % CI 4.189-7.723) than a client (OR = 2.992, 95 % CI 2.301-3.890). Workplace violence had an effect on occurrence of sleep disturbance and when the perpetrators of violence was a boss or colleague at work, the risk for symptoms such as sleep disturbance increased, which indicated the need for appropriate intervention from a workplace healthcare perspective, including preventive education of workplace violence among employees.

    This study examined correlates of making an intimate partner engage in unprotected sex among perpetrators of sexual violence. Based on the Confluence Model, we hypothesized that power and impersonal sex motives would be higher among perpetrators who made a dating partner have unprotected sex. Among a subsample of 78 male college students, significant differences were found for acceptance of verbal pressure, positive attitudes about casual sex, frequency of sexual intercourse, and physical injuries to dating partners. These findings highlight the importance of integrating theories and interventions directed at sexual assault and sexual risk reduction. PMID:20980229

The findings highlighted the need for “risk factor assessment”, showing specific risk factors predicted violence, with sexual violence playing a role. Perpetrators disregard their partners as victims when sexual violence was employed. Qualitative data from female respondents showed that perpetrators use physical assault and sexual violence in their attacks, and their behaviours were fuelled by attitudes that supported/condoned intimate partner violence (IPV.

    Data are presented on young people's sexual victimisation and perpetration from 10 European countries (Austria, Belgium, Cyprus, Greece, Lithuania, the Netherlands, Poland, Portugal, Slovakia and Spain) using a shared measurement tool (N = 3480 participants, aged between 18 and 27 years). Between 19.7 and 52.2% of female and between 10.1 and 55.8% of male respondents reported having experienced at least one incident of sexual victimisation since the age of consent. In two countries, victimisation rates were significantly higher for men than for women. Between 5.5 and 48.7% of male and 2.6 and 14.8% of female participants reported having engaged in a least one act of sexual aggression perpetration, with higher rates for men than for women in all countries. Victimisation rates correlated negatively with sexual assertiveness and positively with alcohol use in sexual encounters. Perpetration rates correlated positively with attitudes condoning physical dating violence and with alcohol use in men, and negatively with sexual assertiveness in women. At the country level, lower gender equality in economic power and in the work domain was related to higher male perpetration rates. Lower gender equality in political power and higher sexual assertiveness in women relative to men were linked to higher male victimisation rates.

    School-based athletic programs remain an important context for violence prevention efforts although a better understanding of how gender attitudes and abuse perpetration differ among athletes is needed. We analyzed baseline survey data from the "Coaching Boys into Men" study-a school-based cluster-randomized trial in 16 high schools in Northern California. We describe relationships among gender-inequitable attitudes, sport type, and recent adolescent relationship abuse perpetration among a sample of male athletes (n = 1,648). Gender-inequitable attitudes (adjusted odds ratio (AOR), 3.26; 95% confidence interval (CI), 2.56, 4.15), participation in both high school football and basketball (AOR, 2.08; 95% CI, 1.37, 3.18), and participation in football only (AOR, 1.50; 95% CI, 1.02, 2.22) emerged as independently associated with recent ARA perpetration. Findings warrant targeted violence prevention efforts among male high school athletes that incorporate discussions of gender attitudes and healthy relationships, especially among sports teams at greater risk of adolescent relationship abuse perpetration.

    Increasingly recognized as a distinct form of childhood maltreatment, children's exposure to intimate partner violence (IPV) has been shown to be associated with an array of negative psychosocial outcomes, including elevated risk for additional violence over the life course. Although studies have identified child exposure to IPV as a predictor of IPV perpetration in adulthood, no review has critically evaluated the methodology of this quantitative work. The present study examines the association between childhood exposure to IPV and the perpetration of IPV in adulthood based on a systematic review of the literature from inception to January 4, 2016. Databases searched included Medline, Embase, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews, Sociological Abstracts and ERIC. Database searches were complemented with backward and forward citation chaining. Studies were critically appraised using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Of 5601 articles identified by the search, 19 studies were included for data extraction. Sixteen of these studies found that child exposure to IPV was significantly and positively associated with adult IPV perpetration; three studies reported null findings. The methodological quality of the studies was low. Work thus far has tended to focus on child exposure to physical IPV and the perpetration of physical IPV within heterosexual contexts. In addition, measures of child exposure to IPV vary in their classification of what exposure entails. We critically discuss the strengths and limitations of the existing evidence and the theoretical frameworks informing this work. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Neuropsychological impairments of the executive functions, memory, attention, intelligence quotient, and empathy have been found in perpetrators of domestic violence (intimate partner violence). These impairments could be partially explained by alcohol abuse, dependence, or traumatic brain injuries. This study reviews the neuropsychological deficits of perpetrators of intimate partner violence. At the same it seeks to integrate and relate these main points with their neuroanatomical correlates. We have also established the relationship between alcohol abuse, dependence, brain damage (including traumatic brain injuries) and those deficits. Scientific literature has been reviewed by means of Google Scholar, PsycINFO, PubMed, Medline and ISI Web of Knowledge. Perpetrators of domestic violence present high mental rigidity, as well as low levels of inhibition, processing speed, verbal and attention skills, and abstract reasoning. Additionally, perpetrators show working and long play memory impairments. Moreover, those deficits could be impaired by traumatic brain injuries and alcohol abuse and/or dependence. Nonetheless, these both variables are not enough to explain the deficits. Functional abnormalities on the prefrontal and occipital cortex, fusiform gyrus, posterior cingulate gyrus, hippocampus, thalamus and amygdala could be associated with these impairments. An analysis of these mechanisms may assist in the development of neuropsychological rehabilitation programmes that could help improve current therapies.

    Substance use disorder (SUD) and post-traumatic stress disorder (PTSD) commonly co-occur. This is of significant concern, given the increased risk for violence perpetration among individuals with this comorbidity. Limited research, however, has examined relationships between SUD, PTSD and violence among individuals longitudinally. Such an investigation is warranted given that substance use and PTSD symptoms can fluctuate over time. This study therefore aims to examine how changes in substance use and PTSD symptom severity are associated with the perpetration of violent crime over time among individuals with comorbid SUD and PTSD. One-hundred and two men and women who met criteria for SUD and PTSD were interviewed four times over a 9-month period. These interviews included measures of past-month violent crime perpetration, substance use and dependence, PTSD symptom severity, and depression and state anxiety symptoms. Generalised estimating equations (GEE) modelled associations between substance use, PTSD and violence. Increased substance use, more severe substance dependence and more severe PTSD symptomology were consistently associated with violent crime over time. Multivariate GEE analyses, however, revealed that the PTSD hyperarousal symptoms, specifically, were independently associated with violence over time. This longitudinal study found that PTSD hyperarousal symptoms were consistently associated with the perpetration of violent crime, further highlighting the potentiating role of PTSD hyperarousal in relation to violence among individuals with SUD. These findings indicate that interventions addressing hyperarousal symptoms have the potential to reduce the susceptibility for violence among individuals with this common comorbidity.

    Domestic violence (DV) is prevalent in low-income and slum-dwelling communities in India. To date, the focus of DV prevention in resource-poor settings has largely been with women. We herein aim to identify correlates of DV perpetration to help inform future primary prevention efforts that focus on behavioral change in men. Utilizing a cross-sectional design, potential correlates of DV perpetration were explored among a geographically-clustered random sample of 100 recently-married men residing in slums in Pune, India. In multivariable regression, DV perpetration was associated with less time spent alone in the relationship post-marriage (standardized β = -0.230, p<0.01), not attaining the "husband ideal" (standardized β = -0.201, p<0.05), poor resilience (standardized β = -0.304, p < .01), having limited definitions of behaviors constituting DV (standardized β = -0.217, p<0.05), and reporting greater jealousy if the participant's spouse were to talk to men outside the family (standardized β = 0.272, p<0.01). The identified correlates should inform components of future DV primary prevention interventions that target men as potential perpetrators or the couple as a unit.

    2017-01-01

    Because of high rates of heavy drinking and dating violence (psychological or physical aggression toward a dating partner) among college men, we examined whether emotion regulation difficulties moderated the association between heavy drinking and dating violence perpetration. One hundred and fifty-eight men were recruited from a large northwestern US university between April 2014 and August 2014. Participants completed an online survey that assessed their emotion regulation difficulties as well as their past year history of heavy episodic drinking (HED; consuming 5+ drinks in 2 hours) and dating violence perpetration. Generalized linear models revealed that the positive association between HED and dating violence perpetration was stronger for men with greater impulse control difficulties and for those who reported limited access to emotion regulation strategies. In addition to continued efforts to reduce heavy drinking among college men, interventions targeting emotion regulation difficulties should be incorporated into standard dating violence intervention and prevention efforts to further reduce the likelihood of dating violence perpetration in this population.

    To investigate associations between Grade 9 and 10 cyber-bullying perpetration and victimization and Grade 11 problem behavior and mental health problems after controlling for risk factors for these outcomes in the analyses. The sample comprised 927 students from Victoria, Australia who completed a modified version of the self-report Communities That Care Youth Survey in Grades 9-11 to report on risk factors, traditional and cyber-bullying perpetration and victimization, problem behavior, and mental health. Complete data on over 650 participants were analyzed. Five per cent of Grade 9 and 10 students reported cyber-bullying perpetration only, 6-8% reported victimization only, and 8-9% both cyber-bullied others and were cyber-bullied. Results showed that cyber-bullying others in Grade 10 was associated with theft in Grade 11, cyber-victimization in Grade 10 was linked with Grade 11 depressive symptoms, and Grade 10 cyber-bullying perpetration and victimization combined predicted Grade 11 school suspension and binge drinking. Prevention approaches that target traditional and cyber-bullying, and established risk factors are necessary. Such multi-faceted programs may also reduce problem behavior and mental health problems.

    This paper defines and analyzes the harassment perpetrated by ETA's terrorist network in the Basque Country, providing a taxonomy of its strategies of psychological violence. The usefulness of this taxonomy has been tested and contrasted by means of a content analysis of 19 testimonies of persons who were the victims of violence by the terrorist network. The taxonomy of strategies of psychological violence is made up of four dimensions that emphasize the actions on the context of the persons affected, and on their emotional state, cognitions, and behaviour. Results show the predominance of emotional and cognitive strategies. Intra-observer and inter-observer reliability analysis in coding showed a Cohen's Kappa coefficient of .92 and .87, respectively. The psychological violence analyzed in this study reflects a form of psychological terrorism that harasses and persecutes a specific sector of the population.

    Few longitudinal studies have examined the pathways through which family violence leads to dating aggression. In the current study the authors used 3 waves of data obtained from 8th- and 9th-grade adolescents (N = 1,965) to examine the hypotheses that the prospective relationship between witnessing family violence and directly experiencing violence and physical dating aggression perpetration is mediated by 3 constructs: (a) normative beliefs about dating aggression (norms), (b) anger dysregulation, and (c) depression. Results from cross-lagged regression models suggest that the relationship between having been hit by an adult and dating aggression is mediated by changes in norms and anger dysregulation, but not depression. No evidence of indirect effects from witnessing family violence to dating aggression was found through any of the proposed mediators. Taken together, the findings suggest that anger dysregulation and normative beliefs are potential targets for dating abuse prevention efforts aimed at youth who have directly experienced violence.

    Maltreatment by parents inhibits a child's ability to form relationships with other children. Given that many sex offenders experienced parental abuse, investigation of their relationships with siblings and peers could provide new directions for early childhood interventions. Interview transcripts of 23 community-dwelling perpetrators of sexual abuse against children were examined in this secondary data analysis. Ages of participants ranged from 20s to 70s, and education ranged from GED to PhD. Phenomenological analysis revealed that neither sibling nor peer relationships adequately promoted participants' capacity for developing and maintaining healthy relationships in adulthood. Until societal preventive actions and early clinical interventions are more successful, the crime of child sexual abuse will continue to be far too common. © 2013.

    Full Text Available Bodies are vulnerable because they are intrinsically linked to death. Bodies are social and they are embedded with meaning. They cannot be extracted from their specific contexts. The nation is also often equated with body politic. As a result individual bodies become the site of security/ insecurity depending on the social location of bodies. Within this discourse, this article tries to locate the bodies of women. It will look at the bodies of women as victims of terror as well as perpetrators of terror. It will try to understand if in these differentiated roles, women are able to break away from stereotypes or are still caught in heteronormative narratives.

    The epidemiology of violence against children is likely to differ substantially by sex and age of the victim and the perpetrator. Thus far, investment in effective prevention strategies has been hindered by lack of clarity in the burden of childhood violence across these dimensions. We produced the first age-specific and sex-specific prevalence estimates by perpetrator type for physical, sexual and emotional violence against children globally. We used random effects meta-regression to estimate prevalence. Estimates were adjusted for relevant quality covariates, variation in definitions of violence and weighted by region-specific, age-specific and sex-specific population data to ensure estimates reflect country population structures. Secondary data from 600 population or school-based representative datasets and 43 publications obtained via systematic literature review, representing 13 830 estimates from 171 countries. Estimates for recent violence against children aged 0-19 were included. The most common perpetrators of physical and emotional violence for both boys and girls across a range of ages are household members, with prevalence often surpassing 50%, followed by student peers. Children reported experiencing more emotional than physical violence from both household members and students. The most common perpetrators of sexual violence against girls aged 15-19 years are intimate partners; however, few data on other perpetrators of sexual violence against children are systematically collected internationally. Few age-specific and sex-specific data are available on violence perpetration by schoolteachers; however, existing data indicate high prevalence of physical violence from teachers towards students. Data from other authority figures, strangers, siblings and other adults are limited, as are data on neglect of children. Without further investment in data generation on violence exposure from multiple perpetrators for boys and girls of all ages, progress

    This article adds to the literature on familicide by providing specific insights from the Italian experience. It presents results of an exploratory investigation into male-perpetrated familicides in Italy between 1992 and 2015. Familicide is defined as the killing of the spouse or intimate partner, and at least one child, at the hand of the other spouse/partner. Incidents of familicide were collated from newspaper reports. We identified 90 cases, resulting in 207 deaths. On average, perpetrators were middle aged ( M = 46.8; age ranging from 25 to 76), and most ( n = 66; 73%) committed, or attempted to commit, suicide. While significant contributory roles were played by health problems and financial worries, the origin of the primary emotional upset for the killers tended to be interpersonal conflicts involving their partners. For those cases with available information ( n = 56; 62%), six types of familicide were also identified on the basis of the murderer's homicidal motivations. Most frequent were three circumstances. 15 cases concerned the "doubly-protective familicide" (which corresponds to the "suicide-by-proxy"), characterized by the preservation of the family in the face of a presumed catastrophic event. Triggers included the killer's financial distress, health troubles, or anxiety associated with other personal problems. 13 cases referred to "doubly-punitive familicide," whose distinctive feature, in addition to punishing the partner because of her estrangement, her infidelity, or other disputes, is to directly involve the child(ren) in the punitive homicidal act. The children are viewed as contributory factors to the killer's stress, or are considered to be in league with the mother. 12 cases exemplified "indirectly-punitive familicide" (also termed "murder-by-proxy"), in which the victimized child(ren) are killed as an extension of the partner. Overall, this typology provides a more nuanced conceptualization of familicide occurrences than those examined

    Prior to the passing of 2009 Human Trafficking Prevention Act (HTPA), human trafficking was underestimated in Taiwan. In the past, domestic trafficking in women and girls often targeted vulnerable groups such as young girls from poor families or minority groups. Since the 1990s, an increasing flow of immigrant women, mainly from Vietnam and Indonesia and some from China, into Taiwan has created a new group of Human Trafficking victims. The current study intends to identify, describe, and categorize reported and prosecuted human trafficking cases involving women and girls according to the HTPA in Taiwan. Using the court proceedings of prosecuted trafficking in women and girls cases under Taiwan's HTPA from all 21 districts in Taiwan from 2009 to 2012 under the title keyword of 'Human Trafficking', this current study aims to categorize different patterns of existing trafficking in women and girls in Taiwan. The analysis is based on 37 court cases, involving 195 victimized women and girls and 118 perpetrators. This study identifies six forms of Human Trafficking victims according to their country of origin, vulnerability status, and means of transport. This study found that women and girls suffer from both labor and sexual exploitation, from mainly domestic male perpetrators. While sexual exploitation is more evenly distributed among citizens and immigrants and affects both adults and minors, labor exploitation seems to be an exclusive phenomenon among women immigrant workers in the data. Human Trafficking cases in Taiwan share many of the similarities of Human Trafficking in other regions, which are highly associated with gender inequality and gender-based vulnerability.

    Objectives To differentiate between forms of intimate partner violence (IPV) (victim only, perpetrator only, or participating in reciprocal violence) and examine risk profiles and pregnancy outcomes. Design Prospective Setting Washington, DC, July 2001 to October 2003 Sample 1044 high-risk African-American pregnant women who participated in a randomized controlled trial to address IPV, depression, smoking, and environmental tobacco smoke exposure. Methods Multivariable linear and logistic regression Main outcome measures Low and very low birth weight, preterm and very preterm birth Results 5% of women were victims only, 12% were perpetrators only, 27% participated in reciprocal violence, and 55% reported no IPV. Women reporting reciprocal violence in the past year were more likely to drink, use illicit drugs, and experience environmental tobacco smoke exposure and were less likely to be very happy about their pregnancies. Women reporting any type of IPVwere more likely to be depressed than those reporting no IPV. Women experiencing reciprocal violence reported highest levels of depression. Women who were victims of IPV were more likely to give birth prior prematurely and deliver low and very low birth weight infants. Conclusions We conclude that women were at highest risk for pregnancy risk factors when they participated in reciprocal violence and thus might be at higher risk for long-term consequences, but women who were victims of intimate partner violence were more likely to show proximal negative outcomes like preterm birth and low birth weight. Different types of interventions may be needed for these two forms of intimate partner violence. PMID:23786367

    We explored the relation between empathy, callous-unemotional (CU) traits, and animal abuse in a sample of 290 seven- to twelve-year-old children whose mothers were exposed to intimate partner violence (IPV). The sample comprises mostly Latino and White participants, and 55% of the children's mothers were born outside the United States (primarily Mexico). To our knowledge, among studies examining child-perpetrated animal abuse, this study is the first to examine empathy levels and one of only a few to examine CU traits. When comparing Griffith Empathy Measure (empathy) and Inventory of Callous-Unemotional Traits (callous-unemotional [CU] traits) scores with those from studies of White schoolchildren, our sample scored lower on affective empathy, higher on cognitive empathy, and lower for overall CU scores as well as Callous and Unemotional subscales. Of 290 children, 47 (16.2%) harmed an animal at least once according to either mother or child report. There were no significant sex or age differences between Abuse and No Abuse groups. The Abuse group scored significantly higher on affective empathy, CU, and Callousness/Unemotional subscales, and significantly lower on cognitive empathy. However, in regression analyses that controlled for income, only lower cognitive empathy and higher CU significantly predicted having abused an animal. In summary, low cognitive empathy (but not affective empathy) and CU traits may serve as reliable predictors of child animal abuse. However, replication of these results is necessary. A larger sample with a high percentage of Latino children whose mothers were exposed to IPV, along with a non-exposed comparison group, would be ideal.

    Despite widespread apartheid-related human rights violations (HRV) and intimate partner violence (IPV) in South Africa, research investigating the influence of HRV on IPV perpetration is scarce. This study analysed data from the South Africa Stress and Health Study, a cross-sectional survey conducted from 2003 to 2004 with 4351 South Africans examining public health concerns associated with apartheid. Analyses were restricted to men who had ever been married or had ever cohabited with a female partner. Logistic regression was used to examine associations between experiences of HRV and lifetime physical IPV perpetration. A total of 772 South Africa men met the study criteria (389 liberation supporters and 383 government supporters). Adjusted logistic regression analyses indicated that among liberation supporters, a significant association existed between experiencing major HRV (AOR 2.40, 95% CI 1.20 to 4.81), custody-related HRV (AOR 6.61, 95% CI 2.00 to 21.83), victimisation of close friends/family members (AOR 3.38, 95% CI 1.26 to 9.07) and physical IPV perpetration. Among government supporters, a significant association was observed between experiencing HRV (AOR 2.99, 95% CI 1.34 to 6.65) and victimisation of close friends/immediate family (AOR 5.42, 95% CI 1.44 to 19.02) and IPV perpetration. This work indicates the importance of men's experiences with HRV with regard to IPV perpetration risk. Future work is needed to understand the mechanisms underlying the observed relationships, particularly regarding mental health and gender norms as suggested by current literature, in order to inform interventions in South Africa and other regions affected by politically motivated conflict.

    Objective To describe the prevalence and patterns of rape perpetration in a randomly selected sample of men from the general adult population, to explore factors associated with rape and to describe how men explained their acts of rape. Design Cross-sectional household study with a two- stage randomly selected sample of men. Methods 1737 South African men aged 18–49 completed a questionnaire administered using an Audio-enhanced Personal Digital Assistant. Multivariable logistic regression models were built to identify factors associated with rape perpetration. Results In all 27.6% (466/1686) of men had raped a woman, whether an intimate partner, stranger or acquaintance, and whether perpetrated alone or with accomplices, and 4.7% had raped in the last 12 months. First rapes for 75% were perpetrated before age 20, and 53.9% (251) of those raping, did so on multiple occasions. The logistic regression model showed that having raped was associated with greater adversity in childhood, having been raped by a man and higher maternal education. It was associated with less equitable views on gender relations, having had more partners, and many more gender inequitable practices including transactional sex and physical partner violence. Also drug use, gang membership and a higher score on the dimensions of psychopathic personality, namely blame externalisation and Machiavellian egocentricity. Asked about why they did it, the most common motivations stemmed from ideas of sexual entitlement. Conclusions Perpetration of rape is so prevalent that population-based measures of prevention are essential to complement criminal justice system responses. Our findings show the importance of measures to build gender equity and change dominant ideas of masculinity and gender relations as part of rape prevention. Reducing men's exposure to trauma in childhood is also critically important. PMID:22216324

  13. G‐LoSA: An efficient computational tool for local structure‐centric biological studies and drug design

    2016-01-01

    Abstract Molecular recognition by protein mostly occurs in a local region on the protein surface. Thus, an efficient computational method for accurate characterization of protein local structural conservation is necessary to better understand biology and drug design. We present a novel local structure alignment tool, G‐LoSA. G‐LoSA aligns protein local structures in a sequence order independent way and provides a GA‐score, a chemical feature‐based and size‐independent structure similarity score. Our benchmark validation shows the robust performance of G‐LoSA to the local structures of diverse sizes and characteristics, demonstrating its universal applicability to local structure‐centric comparative biology studies. In particular, G‐LoSA is highly effective in detecting conserved local regions on the entire surface of a given protein. In addition, the applications of G‐LoSA to identifying template ligands and predicting ligand and protein binding sites illustrate its strong potential for computer‐aided drug design. We hope that G‐LoSA can be a useful computational method for exploring interesting biological problems through large‐scale comparison of protein local structures and facilitating drug discovery research and development.

    2009-01-01

    The R4SA GUI mentioned in the immediately preceding article is a userfriendly interface for controlling one or more robot(s). This GUI makes it possible to perform meaningful real-time field experiments and research in robotics at an unmatched level of fidelity, within minutes of setup. It provides such powerful graphing modes as that of a digitizing oscilloscope that displays up to 250 variables at rates between 1 and 200 Hz. This GUI can be configured as multiple intuitive interfaces for acquisition of data, command, and control to enable rapid testing of subsystems or an entire robot system while simultaneously performing analysis of data. The R4SA software establishes an intuitive component-based design environment that can be easily reconfigured for any robotic platform by creating or editing setup configuration files. The R4SA GUI enables event-driven and conditional sequencing similar to those of Mars Exploration Rover (MER) operations. It has been certified as part of the MER ground support equipment and, therefore, is allowed to be utilized in conjunction with MER flight hardware. The R4SA GUI could also be adapted to use in embedded computing systems, other than that of the MER, for commanding and real-time analysis of data.

    2018-05-01

    Despite the high prevalence of intimate partner violence (IPV) perpetration by men receiving substance use treatment, little is known about their help-seeking behaviors for IPV. A secondary analysis of a mixed-methods study of men receiving substance use treatment who perpetrated IPV examined the prevalence, characteristics, and barriers associated with IPV perpetration disclosure and help-seeking. In total, 170 men were interviewed using a structured questionnaire, and a subsample of 20 were interviewed in-depth about their experiences. Logistic regression determined variables associated with disclosure and help-seeking. Thematic analysis of the in-depth interviews explored barriers to disclosure and help-seeking. Only half the participants had told anyone about their IPV perpetration and about one quarter reported having sought any sort of support. Whereas participants were more likely to disclose their IPV perpetration to informal resources (such as friends or family), they tended to seek help from formal resources (such as health professionals or the police). A greater proportion of physical IPV perpetrators, who had disclosed, had been arrested or had police involvement for IPV, suggesting that their disclosure may not have been voluntary. The following themes emerged from the qualitative data about the barriers to disclosure and help-seeking for IPV perpetration: fear that their children would be taken into care by social services, shame and embarrassment, and a minimization or normalization of their behavior. In addition, many participants highlighted that they had never been previously asked about IPV during treatment for substance use and stressed the need for greater expertise in or knowledge of this topic from specialist services. Substance use treatment services should enquire about men's relationships and IPV perpetration to facilitate disclosure and provide support. Further research is necessary to determine the context of disclosure and help

    To investigate the improved clearance effect of avidin (Av) and streptavidin-gal (SA - gal) for blood radiolabeled biotinylated antibody in pre-targeting radio-immuno therapy (RIT) of colon carcinoma xenograft models. Biotinylated antibody radiolabeled with 131 I was injected into the nude mice bearing the colon carcinoma via the tail vein. 24 h later, in 2 test groups, SA-gal or Av at a 10 - fold molar excess of antibody was intraperitoneally injected into the animals whereas no any chase agents were given to the control animals. Animals were killed for biodistribution study at 30h after 131 I-labelled biotinylated antibody administration. Results showed that Av and SA-gal took the effect of chase very fast. At 6h after injection, the blood level of radioactivity decreased very fast. The tumor/blood ratios of control group, Av chase group, SA-gal chase group were 0.42, 2.09, 5.23 respectively, P < 0.05 and P < 0.01 for the latter two groups as compared other control groups. Compared with Av, SA-gal showed better chase effect, its T/B ratios was 5.23, significantly higher than 2.09 of Av (P < 0.01). In the tissue biodistributions, relatively high non-specific radioactivity uptakes in non-liver organs were seen in Av chase group. Utilized in pre-targeting RIT, both Av and SA-gal could make the blood level of radioactivity decrease quickly and considerably improves tumor T/NT ratios. The chase effect of SA-gal was superior to that of avidin

  3. Molecular Characterization of the Plant Growth Promoting Bacterium Enterobacter sp. SA187 upon Contact with Arabidopsis thaliana

    Salt stress is a severe environmental challenge in agriculture, limiting the quality and productivity of the crops around the globe. Plant growth promoting rhizobacteria (PGPR) is proposed as a friendly solution to overcome those challenges. The desert plant endophytic bacterium, Enterobacter sp. SA187 has shown plant growth promotion and salt stress tolerance beneficial effect on the model plant Arabidopsis thaliana in vitro as well as under the field conditions on different crops. SA187 has a distinguished morphology of yellow colonies (SA187Y) that could be due to carotenoid biosynthesis. However, the bacteria tend to lose the yellow color upon incubation with the plants and the colonies turn to white (SA187W). In comparison to SA187Y, SA187W shows 50% reduction on the beneficial impact on A. thaliana fresh and dry weight of root and shoot system. By counting the CFU/plant, we showed that SA187Y and SA187W both have similar colonization rate in both shoots and roots. Under non-salt conditions, optimal bacterial colonization was observed on day 8 after inocubation, however, under the salt stress condition, the optimal colonization was observed at day 4. Moreover, during the time period of the incubation of the SA187Y with the plants, there was a consistent noticeable loss of the yellow color of the colonies. This change in color is only observed eight days after transfer and the number of white colonies increases with the increase of the incubation time. In addition, SA187W was GFP-tagged by Tn7 transposon system and visualized by confocal laser scanning microscopy. The SA187W-GFP colonies have shown a similar colonization pattern as SA187Y-GFP, bacteria were colonizing the differentiation zone and cell elongation zone in the roots. Finally, the gene expression of the carotenoid biosynthesis pathways genes in SA187Y showed an overall higher gene expression compared to SA187W. In conclusion, the color loss seems to affect the beneficial impact of the bacteria on

    Many human Gram-negative bacterial pathogens express a Type Three Secretion Apparatus (T3SA), including among the most notorious Shigella spp., Salmonella enterica, Yersinia enterocolitica and enteropathogenic Escherichia coli (EPEC). These bacteria express on their surface multiple copies of the T3SA that mediate the delivery into host cells of specific protein substrates critical to pathogenesis. Shigella spp. are Gram-negative bacterial pathogens responsible for human bacillary dysentery. The effector function of several Shigella T3SA substrates has largely been studied but their potential cellular targets are far from having been comprehensively delineated. In addition, it is likely that some T3SA substrates have escaped scrutiny as yet. Indeed, sequencing of the virulence plasmid of Shigella flexneri has revealed numerous open reading frames with unknown functions that could encode additional T3SA substrates. Taking advantage of label-free mass spectrometry detection of proteins secreted by a constitutively secreting strain of S. flexneri, we identified five novel substrates of the T3SA. We further confirmed their secretion through the T3SA and translocation into host cells using β-lactamase assays. The coding sequences of two of these novel T3SA substrates (Orf13 and Orf131a) have a guanine-cytosine content comparable to those of T3SA components and effectors. The three other T3SA substrates identified (Orf48, Orf86 and Orf176) have significant homology with antitoxin moieties of type II Toxin-Antitoxin systems usually implicated in the maintenance of low copy plasmids. While Orf13 and Orf131a might constitute new virulence effectors contributing to S. flexneri pathogenicity, potential roles for the translocation into host cells of antitoxins or antitoxin-like proteins during Shigella infection are discussed.

    Full Text Available Many human Gram-negative bacterial pathogens express a Type Three Secretion Apparatus (T3SA, including among the most notorious Shigella spp., Salmonella enterica, Yersinia enterocolitica and enteropathogenic Escherichia coli (EPEC. These bacteria express on their surface multiple copies of the T3SA that mediate the delivery into host cells of specific protein substrates critical to pathogenesis. Shigella spp. are Gram-negative bacterial pathogens responsible for human bacillary dysentery. The effector function of several Shigella T3SA substrates has largely been studied but their potential cellular targets are far from having been comprehensively delineated. In addition, it is likely that some T3SA substrates have escaped scrutiny as yet. Indeed, sequencing of the virulence plasmid of Shigella flexneri has revealed numerous open reading frames with unknown functions that could encode additional T3SA substrates. Taking advantage of label-free mass spectrometry detection of proteins secreted by a constitutively secreting strain of S. flexneri, we identified five novel substrates of the T3SA.

    This study examines violence experienced in work and personal contexts and relation to HIV risk factors in these contexts among female sex workers (FSW) in Andhra Pradesh, India. FSW at least 18 years of age (n=2335) were recruited through three rounds of respondent-driven sampling between 2006 and 2010 for a survey on HIV risk. Using crude and adjusted logistic regression models, any sexual/physical violence (last 6 months) perpetrated by clients and husbands were separately assessed in association with accepting more money for sex without a condom (last 30 days), consistent condom use with clients and husbands (last 30 days), and sexually transmitted infection (STI) symptoms (last 6 months). The mean age among participants was 32, 22% reported being currently married, and 22% and 21% reported physical/sexual violence by clients and husbands, respectively. In adjusted logistic regression models, FSW who experienced client violence were more likely to report accepting more money for unprotected sex trades (adjusted OR (AOR)=1.7; 95% CI 1.4 to 2.2), less likely to report consistent condom use with clients (AOR=0.6; 95% CI 0.5 to 0.7) and more likely to report STI symptoms (AOR=3.5; 95% CI 2.6 to 4.6). Women who reported husband violence were more likely to report accepting more money for unprotected sex trades (AOR=2.1; 95% CI 1.2 to 3.7), less likely to report consistent condom use with clients (AOR=0.5; 95% CI 0.3 to 0.8) and more likely to report STI symptoms (AOR=2.6; 95% CI 1.6 to 4.1). Among FSW, experiences of violence in work and personal contexts are associated with sexual HIV risk behaviours with clients as well as STI symptoms. Published by the BMJ Publishing Group Limited.

    This paper describes the conceptual design of cryostat for the JT-60SA, which is a research device for the commercial production of electricity from the controlled fusion reaction in the future. JT-60SA is designed to be a fully superconducting device and cryostat is one of the main components to allow the normal operation. Cryostat covers up the tokamak device, which is 15 m of total height and 7 m of radius, and supports the total weight of 25 MN. Cryostat components consist of vessel body, gravity support and auxiliary systems, such as 80 K thermal shield and vacuum exhaust. The functions required of cryostat are these three, thermal insulation for superconducting magnets, gravity support for the tokamak device, and bio-shielding. The design conditions for each cryostat component are outlined and the features of auxiliary systems such as capacity of vacuum exhaust related to 80 K thermal shield design are summarized

    Intimate partner violence (IPV) rates are disproportionately high among sexual minority populations, with increasing evident that gay men experience IPV at the same rates as heterosexual women. This study examines the relationship between self-reported condomless anal intercourse (CAI) and IPV among a sample of 750 gay and bisexual men. Participants answered questions regarding recent receipt and perpetration of IPV using the IPV-GBM Scale (Cronbach Alpha 0.90). Of the sample, 46.1% reported recent receipt of any type of IPV and 33.6% reported recent perpetration of any type of IPV. Overall, 55.1% of participants reported CAI at last sex. Significant associations were determined between several forms of IPV and increased odds of reporting CAI at last sex. These findings suggest that IPV may be a risk factor for CAI among men who have sex with men, and highlight the need to understand the IPV prevention and care needs of this population.

    Full Text Available From exploratory researches done in Latin America and Portugal that have mapped programs for men perpetrators of violence against women, this paper intends to problematize how these men have been regarded by public policies. As to the methodology, visits were made to each program, along with routine observations and access to the materials produced by them, as well as coordinators interviews. The majority of initiatives have been developed by NGOs, however, in Brazil, governmental interventions are growing since the Maria da Penha Law was enacted. In Portugal, four programs were visited, three of which were linked to universities and the other to a hospital. While some difficulties are identified to give support to the male demand, it is important to emphasize the success of programs that propose educational and reflexive interventions. Thus, through reinforcement of public policies and interventions to give visibility for men perpetrators of violence, the possibility to promote changes in this context can be widely expanded.

    The prevalence of alcohol use and dating violence are shockingly high among male college students, making this a particularly high-risk group for alcohol-related aggression. Expanding upon previous research, the current study examined the relations between three indicators of alcohol use and three types of dating violence among 204 male college students. We also examined whether hazardous drinkers reported more violence perpetration than non-hazardous drinkers. Results demonstrated that alcohol use was related to all types of aggression, and hazardous drinkers are at greater risk of violence perpetration than non-hazardous drinkers. Implications for dating violence prevention programs and future research are discussed. © The Author(s) 2014.

    In the wake of several highly publicized adolescent suicides attributed to bullying victimization, national attention has been brought to bear on the profound public health problem of bullying. This article reviews the extant literature on the associations between bullying perpetration, victimization, and thoughts of or attempts at suicide and proposes five potential mediators, namely depression, anxiety, low self-esteem, loneliness, and hopelessness, that may explain this relationship. Numerous studies have found empirical support for the interrelations between internalizing behaviors and both bullying perpetration and victimization and suicide. We find that further longitudinal research needs to be conducted to more conclusively determine the role and causal ordering these various psychosocial factors may play in bullying perpetration, victimization, and suicide. Although the research literature implies causal directions among all these potential mediators, untangling the unique influence of bullying perpetration, victimization, and bully victimization on suicide and its mechanisms of action has major research and practice implications. © The Author(s) 2014.

    Although mental health impact of gender based violence has been documented for many decades, the impact of the socio-cultural dimensions and type of perpetrator on mental health outcomes has not been described outside of developed countries. We explore depression symptomatology four to six weeks post-rape in South Africa and examine whether this differs according to the circumstances of the rape. 140 participants recruited from public hospital services in the Eastern and Western Cape provinces were interviewed within two weeks after completing the post exposure prophylaxis (PEP) medication. A structured questionnaire was used to collect data on socio-demographic and sexual assault characteristics including perpetrator. Depressive symptomatology was measured using the Centre for Epidemiological Studies Depression Scale. 84.3% (95% CI: 78.1-90.3) women were found to have high levels of depressive symptoms, but lower levels were found among women raped in circumstances in which there was a lesser likelihood of blame such as those raped by strangers rather than intimate partners (Odds Ratio: (OR) 0.28 (95% Confidence Intervals (CI): 0.11-0.69) and higher levels were associated with experiencing four or more side effects related to PEP medication (OR: 3.79: CI: 1.03-13.94). Receiving support and severe sexual assaults (involving weapons and multiple perpetrators) were not associated with depression. The study does not support the general assumption that more violent rape causes more psychological harm. These results have important implications for individual treatment because it is more generally assumed that multiple perpetrator rapes, stranger rapes and those with weapons would result in more psychological trauma and thus more enduring symptoms. Our findings point to the importance of understanding the socio-cultural dimensions, including dynamics of blame and stigma, of rape on mental health sequelae.

    Addressing gender norms is integral to understanding and ultimately preventing violence in both adolescent and adult intimate relationships. Males are affected by gender role expectations which require them to demonstrate attributes of strength, toughness, and dominance. Discrepancy stress is a form of gender role stress that occurs when boys and men fail to live up to the traditional gender norms set by society. Failure to live up to these gender role expectations may precipitate this experience of psychological distress in some males which, in turn, may increase the risk to engage in physically and sexually violent behaviors as a means of demonstrating masculinity. Five-hundred eighty-nine adolescent males from schools in Wayne County, Michigan completed a survey assessing self-perceptions of gender role discrepancy, the experience of discrepancy stress, and history of physical and sexual dating violence. Logistic regression analyses indicated boys who endorsed gender role discrepancy and associated discrepancy stress were generally at greater risk to engage in acts of sexual violence but not necessarily physical violence. Boys who experience stress about being perceived as "sub-masculine" may be more likely to engage in sexual violence as a means of demonstrating their masculinity to self and/or others and thwarting potential "threats" to their masculinity by dating partners. Efforts to prevent sexual violence perpetration among male adolescents should perhaps consider the influence of gender socialization in this population and include efforts to reduce distress about masculine socialization in primary prevention strategies.

    Drawing on the cognitive information-processing model of aggression and the general aggression model, we explored why adolescents become addicted to online games and how their immersion in online games affects school violence perpetration (SVP). For this purpose, we conducted statistical analyses on 1,775 elementary and middle school students who resided in northern districts of Seoul, South Korea. The results validated the proposed structural equation model and confirmed the statistical significance of the structural paths from the variables; that is, the paths from child abuse and self-esteem to SVP were significant. The levels of self-esteem and child abuse victimization affected SVP, and this effect was mediated by online game addiction (OGA). Furthermore, a multigroup path analysis showed significant gender differences in the path coefficients of the proposed model, indicating that gender exerted differential effects on adolescents' OGA and SVP. Based on these results, prevention and intervention methods to curb violence in schools have been proposed. © The Author(s) 2015.

    Violence against children by peers is a global public health problem. We aimed to assess factors associated with peer violence victimization among primary school children in Uganda. We conducted multilevel multivariable logistic regression analyses of cross-sectional data from 3706 primary students in 42 Ugandan primary schools. Among primary school students, 29% and 34% had ever experienced physical and emotional violence perpetrated by their peers, respectively. Factors strongly associated with both physical and emotional violence were similar and overlapping, and included exposure to interparental violence, having an attitude supportive of violence against children from school staff, not living with biological parents, working for payment, and higher SDQ score. However, we found that younger age, sharing sleeping area with an adult and achieving a higher educational performance score, were specifically associated with physical violence. On the other hand, being female, walking to school, reporting disability and eating one meal on the previous day, were particularly associated with emotional violence. Interventions to reduce peer violence should focus on family contexts, school environments and those with poor socio-economic status may need extra support. Copyright © 2017.

  5. Opportunities for mourning when grief is disenfranchised: descendants of Nazi perpetrators in dialogue with Holocaust survivors.

    Science.gov (United States)

    Livingston, Kathy

    2010-01-01

    This article explores the concepts of unmourned and disenfranchised grief as a way to understand the experiences of adult children of Nazi perpetrators, who grew up with cultural norms of grieving alone or in silence. The scholarly literature on descendants of Nazis reflects a group unlikely to warrant empathy or support from others because of the stigma surrounding their family's possible involvement in the Holocaust atrocities. This article uses, as a case study approach, the testimony given by Monika Hertwig, the adult daughter of a high ranking Nazi, who appears in the documentary film, Inheritance. From the perspective of disenfranchised grief, defined as grief that is not socially recognized or supported, the article links Monika's testimony with existing research from in-depth interviews with other descendants of Nazis to suggest that, as a group, they lacked permission to grieve their deceased parents, acknowledgment of their grief, and opportunities to mourn. Based on the theory that the effects of grief can be transgenerational, the disenfranchisement experienced by the "children of the Third Reich" does not have to pass to subsequent generations if opportunities for mourning are made possible and some resolution of grief occurs. Studies have shown that ongoing dialogue groups between Holocaust survivors and descendants of Nazis provide opportunities for mourning to both groups.

    This systematic review examined 140 outcome evaluations of primary prevention strategies for sexual violence perpetration. The review had two goals: 1) to describe and assess the breadth, quality, and evolution of evaluation research in this area; and 2) to summarize the best available research evidence for sexual violence prevention practitioners by categorizing programs with regard to their evidence of effectiveness on sexual violence behavioral outcomes in a rigorous evaluation. The majority of sexual violence prevention strategies in the evaluation literature are brief, psycho-educational programs focused on increasing knowledge or changing attitudes, none of which have shown evidence of effectiveness on sexually violent behavior using a rigorous evaluation design. Based on evaluation studies included in the current review, only three primary prevention strategies have demonstrated significant effects on sexually violent behavior in a rigorous outcome evaluation: Safe Dates (Foshee et al., 2004); Shifting Boundaries (building-level intervention only, Taylor, Stein, Woods, Mumford, & Forum, 2011); and funding associated with the 1994 U.S. Violence Against Women Act (VAWA; Boba & Lilley, 2009). The dearth of effective prevention strategies available to date may reflect a lack of fit between the design of many of the existing programs and the principles of effective prevention identified by Nation et al. (2003).

  7. Dating the abusive head trauma episode and perpetrator statements: key points for imaging

    Shaken baby syndrome/abusive head trauma is a leading cause of morbidity and mortality in infants. The presence of a diffuse subdural hematoma without evidence of accident is a key diagnostic clue. The hematoma is typically attributed to rupture of the cerebral bridging veins due to violent shaking, with or without impact. Dating the incident, however, remains controversial. The aim of this article is to review the most reliable features used for dating the incident, based on both legal statements by perpetrators and medical documentation. The key points are: 1) The high (yet likely underestimated) frequency of repeated shaking is around 50%, 2) Children do not behave normally immediately after shaking, and the time of onset of even mild symptoms appears to be the best clue for dating the incident and 3) Brain imaging provides strong indicators of ''age-different'' injuries but the ranges for dating the causal event are wide. The density pattern in a single subdural hematoma location provides no reliable clues for assessing repeated violence. Only the finding of different density in two distant subdural hematomas argues in favor of ''age-different'' injuries, i.e. repeated violence. MRI is difficult to interpret in terms of dating subdural hemorrhages and must be analyzed in conjunction with CT. Most importantly, all of the child's previous clinical and radiological data must be carefully studied and correlated to provide accurate information on the date and repetition of the trauma.

The hematoma is typically attributed to rupture of the cerebral bridging veins due to violent shaking, with or without impact. Dating the incident, however, remains controversial. The aim of this article is to review the most reliable features used for dating the incident, based on both legal statements by perpetrators and medical documentation. The key points are: 1) The high (yet likely underestimated) frequency of repeated shaking is around 50%, 2) Children do not behave normally immediately after shaking, and the time of onset of even mild symptoms appears to be the best clue for dating the incident and 3) Brain imaging provides strong indicators of ''age-different'' injuries but the ranges for dating the causal event are wide. The density pattern in a single subdural hematoma location provides no reliable clues for assessing repeated violence. Only the finding of different density in two distant subdural hematomas argues in favor of ''age-different'' injuries, i.e. repeated violence. MRI is difficult to interpret in terms of dating subdural hemorrhages and must be analyzed in conjunction with CT. Most importantly, all of the child's previous clinical and radiological data must be carefully studied and correlated to provide accurate information on the date and repetition of the trauma.

    Prostitute women have the highest homicide victimization rate of any set of women ever studied. We analyzed nine diverse homicide data sets to examine the extent, trends, and perpetrators of prostitution-related homicide in the United States. Most data sources substantially under-ascertained prostitute homicides. As estimated from a conservative capture-recapture analysis, 2.7% of female homicide victims in the United States between 1982 and 2000 were prostitutes. Frequencies of recorded prostitute and client homicides increased substantially in the late 1980s and early 1990s; nearly all of the few observed pimp homicides occurred before the late 1980s. These trends may be linked to the rise of crack cocaine use. Prostitutes were killed primarily by clients, clients were killed mainly by prostitutes, and pimps were killed predominantly by pimps. Another conservative estimate suggests that serial killers accounted for 35% of prostitute homicides. Proactive surveillance of, and evidence collection from, clients and prostitutes might enhance the investigation of prostitution-related homicide.

    Chemical peeling with salicylic acid in polyethylene glycol vehicle (SA-PEG), which specifically acts on the stratum corneum, suppresses the development of skin tumors in UVB-irradiated hairless mice. To elucidate the mechanism through which chemical peeling with SA-PEG suppresses skin tumor development, the effects of chemical peeling on photodamaged keratinocytes and cornified envelopes (CEs) were evaluated in vivo. Among UVB-irradiated hairless mice, the structural atypia and expression of p53 protein in keratinocytes induced by UVB irradiation were intensely suppressed in the SA-PEG-treated mice 28 days after the start of weekly SA-PEG treatments when compared to that in the control UVB-irradiated mice. Incomplete expression of filaggrin and loricrin in keratinocytes from the control mice was also improved in keratinocytes from the SA-PEG-treated mice. In photo-exposed human facial skin, immature CEs were replaced with mature CEs 4 weeks after treatment with SA-PEG. Restoration of photodamaged stratum corneum by treatment with SA-PEG, which may affect remodeling of the structural environment of the keratinocytes, involved the normalization of keratinocyte differentiation and suppression of skin tumor development. These results suggest that the stratum corneum plays a protective role against carcinogenesis, and provide a novel strategy for the prevention of photo-induced skin tumors.

    Full Text Available Throughout the 20th century, genocide has claimed many lives across the world. In Rwanda, the Genocide against the Tutsi was perpetrated with unprecedented violence and took the lives of more than one million. In the aftermath of the genocide, the interpersonal relationships between genocide survivors and former genocide perpetrators as well as their respective family members was undermined. Through Prison Fellowship Rwanda, former genocide perpetrators and survivors of genocide were brought together in reconciliation villages as a way of restoring their relationships. Drawing on interviews and focus group discussion with members of five reconciliation villages, this study uses a qualitative approach to examine how these villages contribute to the restoration of relationship between conflicting parties in the aftermath of the genocide against the Tutsi in Rwanda. The findings indicate that living together in reconciliation village combined with economic joint activities provided a favorable space in which negative-dehumanizing attitudes were overcome, while positive-re-humanizing attitudes were fostered. Additionally, the village offered members an opportunity for communication, reduced prejudice and fear among them, and generated trust in the community.

    The present study adds to extant literature on the association between microfinance participation and intimate partner violence (IPV) by assessing a national sample of men married to microfinance participants. The key objective was to assess whether there was a positive association between wives' microfinance participation and men's perpetration and justification of IPV in urban areas of Bangladesh. This study is based on a population-based secondary data analysis. In this cross-sectional study, data from a national sample of men from the 2007 Bangladesh Demographic and Health Survey were analysed using logistic regression analyses. IPV perpetration was measured using a modified Conflict Tactics Scale and justification of IPV was measured based on 'justification of wife beating' statements with which men agreed or disagreed. Men married to microfinance participants were not significantly different from men married to non-participants of microfinance in terms of IPV perpetration in both urban and rural areas. However, the interaction effect of wives' microfinance participation and urban living on men's justification of IPV revealed a significant and positive beta coefficient. Specifically, wives' participation in microfinance was positively associated with men's justification of IPV in urban areas (β = 0.51, P men and women.

    Although a robust literature documents a positive association between alcohol and intimate partner violence (IPV), there is limited temporal research on this relation. Moreover, the role of marijuana in influencing IPV has been mixed. Thus, the primary aim of the current study was to examine the temporal relationship between alcohol and marijuana use and dating violence perpetration. A secondary aim was to examine whether angry affect moderated the temporal relation between alcohol and marijuana use and IPV perpetration. Participants were college women who had consumed alcohol in the previous month and were in a dating relationship (N = 173). For up to 90 consecutive days, women completed daily surveys that assessed their alcohol use, marijuana use, angry affect (anger, hostility, and irritation), and violence perpetration (psychological and physical). On alcohol use days, marijuana use days, and with increases in angry affect, the odds of psychological aggression increased. Only alcohol use days and increases in angry affect increased the odds of physical aggression. Moreover, the main effects of alcohol and marijuana use on aggression were moderated by angry affect. Alcohol was positively associated with psychological and physical aggression when angry affect was high, but was unrelated to aggression when angry affect was low. Marijuana use was associated with psychological aggression when angry affect was high. Findings advance our understanding of the proximal effect of alcohol and marijuana use on dating violence, including the potential moderating effect of angry affect on this relation.

    The current study examined characteristics of bullying involvement and social connectedness in relation to suicide ideation and attempts in a sample of youth who report bully victimization, bully perpetration, and/or low social connectedness. The sample was comprised of 321 youth (67% female), ages 12-15 years (M = 13.6), recruited from an emergency department in the Midwest region of the United States. Results indicated that lower levels of social connectedness and higher levels of bully victimization and perpetration were significantly associated with suicide ideation and attempts. Level of social connectedness did not moderate the relationship between bullying involvement and suicide risk. The associations between the severity of subtypes of bully victimization and perpetration (verbal, relational, physical), electronic bullying involvement, and suicide risk were examined. Results highlight a continuum in severity of bullying involvement and social connectedness associated with suicide risk. Implications of these results are discussed.

    To determine the accuracy of Helicobacter pylori Stool Antigen test (HpSA), compared with endoscopic histopathology for the diagnosis of gastric Helicobecter pylori infection. A total of 50 patients underwent endoscopy for gastric antral mucosal tissue biopsy for histopathology of H.pylori and advised for HpSA. Patient's information including age, gender, past history, presenting signs and symptoms, results of HpSA and histopathology were recorded. Sensitivity analysis was performed to calculate sensitivity, specificity, and predictive values of HpSA. Among 50 patients, 48% males and 52% females (M: F 1: 1.08), a total of 27 (54%) were true positive while 20 (40%) were true negative. Two patients were false negative and only one was false positive. Sensitivity of HpSA was, therefore, 93.1%, specificity 95% and positive and negative predictive values were 96.42% and 90.9% respectively. Helicobacter pylori stool antigen was an accurate and reliable test for the diagnosis of gastric H. pylori infection. (author)

    A weld thermal simulation technique has been used to investigate the metallurgical response of SA508 class II material during welding. Dynamic Ac 1 and Ac 3 data, grain growth kinetics and continuous cooling transformation diagrams have been measured. The heat affected zone structure, grain size and precipitate distribution are described in terms of the weld thermal cycle experienced and compared with a weld heat affected zone. The as-welded hardness and tempering response of a range of possible heat affected zone structures has been established. The tempering effects of various weld thermal cycles are calculated from isothermal tempering data. The likely tempering effects during welding are estimated and compared with the tempering of actual welds during welding and in subsequent conventional post weld heat treatment. 16 figures, 6 tables

    Vesamicol is a leading compound for positron emission tomography (PET) and single photon emission computed tomography (SPECT) tracers for mapping the vesicular acetylcholine transporter (VAChT). Recently, we found that (+)-p-methylvesamicol ((+)-PMV) has low affinity for VAChT (K i =199 nM), but has moderate to high affinity for sigma receptors: K i =3.0 nM for sigma 1 and K i =40.7 nM for sigma 2 , and that sigma 1 -selective SA4503 (K i =4.4 nM for sigma 1 and K i =242 nM for sigma 2 ) has moderate affinity for VAChT (K i =50.2 nM). In the present study, we examined the potential of (+)-[ 11 C]PMV as a PET radioligand for mapping sigma 1 receptors as compared with [ 11 C]SA4503. In rat brain, similar regional distribution patterns of (+)-[ 11 C]PMV and [ 11 C]SA4503 were shown by tissue dissection and by ex vivo autoradiography. Blocking experiments using (±)-PMV (-)-vesamicol, SA4503, haloperidol and (±)-pentazocine showed that the two tracers specifically bound to sigma 1 receptors, and that [ 11 C]SA4503 exhibited greater specific binding than (+)-[ 11 C]PMV. No sign of VAChT-specific binding by [ 11 C]SA4503 was observed in the striatum, which is rich in VAChT sites. In conclusion, (+)-[ 11 C]PMV specifically bound to sigma 1 receptors in the brain, but to a lesser extent than [ 11 C]SA4503, suggesting that (+)-[ 11 C]PMV is a less preferable PET ligand than [ 11 C]SA4503. On the other hand, the moderate affinity of [ 11 C]SA4503 for VAChT is negligible in vivo

    The microstructural characteristics and mechanical properties of SA508 Gr.3 Mn-Mo-Ni low alloy steel and SA508 Gr.4N Ni-Mo-Cr low alloy steel were investigated. The differences in the stable phases between these two low alloy steels were evaluated by means of a thermodynamic calculation using ThermoCalc. They were then compared to microstructural features and correlated with mechanical properties. Mn-Mo-Ni low alloy steel shows the upper bainite structure which has the coarse cementite in the lath boundaries. However, Ni-Mo-Cr low alloy steel shows the mixture of lower bainite and tempered martensite structure that homogeneously precipitates the small carbides such as M{sub 23}C{sub 6} and M{sub 7}C{sub 3} due to an increase of hardenability and Cr addition. In the mechanical properties, Ni-Mo-Cr low alloy steel has higher strength and toughness than Mn-Mo-Ni low alloy steel. Ni and Cr additions increase the strength by solid solution hardening. Besides, microstructural changes from upper bainite to tempered martensite improve the strength of the low alloy steel by grain refining effect. And the changes in the precipitation behavior by Cr addition improve the ductile-brittle transition behavior along with a toughening effect of Ni addition.

    Friction welding of tube to tube plate using an external tool (FWTPET) is a relatively newer solid state welding process used for joining tube to tube plate of either similar or dissimilar materials with enhanced mechanical and metallurgical properties. In the present study, FWTPET has been used to weld SA 213 (Grade T12) tube with SA 387 (Grade 22) tube plate. The welded samples are found to have satisfactory joint strength and the Energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD) study showed that inter metallic compound is absent in the weld zone. The different weld joints have been identified and the phase composition is found using EDX and XRD. Microstructures have been analyzed using optical and Scanning electron microscopy (SEM). The mechanical properties such as hardness, compressive shear strength and peel test for different weld conditions are studied and the hardness survey revealed that there is increase in hardness at the weld interface due to grain refinement. The corrosion behavior for different weld conditions have been analyzed and the weld zone is found to have better corrosion resistance due to the influence of the grain refinement after FWTPET welding process. Hence, the present investigation is carried out to study the behavior of friction welded dissimilar joints of SA 213 tube and SA 387 tube plate joints and the results are presented. The present study confirms that a high quality tube to tube plate joint can be achieved using FWTPET process at 1120 rpm.

    2006-01-01

    To examine bullying within nursing from a micro-sociological perspective and elucidate interactive mechanisms contributing to its causes and continuation within the nursing profession. The paper is part of a doctoral research study into bullying within nursing. It considers issues pertinent to management, and in the role of negotiated interactions within the National Health Service when dealing with bullying problems. The complex dynamics involved can be problematic for management when dealing with bullying, while often managers have been targets of bullying themselves and not infrequently accused of it. Features of bullying activity are explored, along with issues of target and bully awareness, a central feature in bullying negotiations. Issues of awareness and emergence of bullying behaviour have been identified through vignettes and unstructured interviews, and the research has identified complex interactive events in the creation and maintenance of nurse bullying activity. It is hoped that with a clearer understanding of such mechanisms and manifestations that bullying in the workplace can be reduced or eliminated. The paper is of practical use to nurse managers in illuminating such mechanisms and bringing bullying awareness to the fore. Such activity is ultimately damaging to the organization in both cost and time; and significant for professional practice by its impact upon the nurse and their work in supportive and safe environments. It will also to allow managers to consider their own practice and reactions to bullying activity within the profession. The overall findings from the research point strongly to bullying activity being essentially 'learned behaviour' within the workplace rather than any predominantly psychological deficit within individual perpetrators and targets.

    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.

  9. Perpetrators or Preventers? The Double Role of Corporations in Child Trafficking in a Global Context

    Full Text Available In recent years, the engagement of corporations in child trafficking has become a matter of growing importance. Many corporations have adopted global subcontracting systems and complex structures that boost their productivity and profits, but might also create more opportunities for trafficking and exploitation of both adults and children. Taking this context into account, the ways in which corporations can commit child trafficking will be explored and exemplified to highlight their diversity. This paper also offers a brief overview of the response given by international and European anti-trafficking instruments concerning corporate criminal liability for child trafficking. Moreover, the mechanisms adopted by some companies to prevent trafficking and promote transparency within their supply chains will also be addressed. Overall, this paper aims to illustrate the pivotal role of corporations from two perspectives: as potential perpetrators of this serious crime, and as necessary actors to prevent it.  El compromiso empresarial sobre el tráfico infantil es un asunto de creciente importancia. Muchas corporaciones han adoptado sistemas globales de subcontrataciones y complejas estructuras que incrementan su productividad y sus beneficios, pero que también podrían crear más oportunidades para la trata y la explotación de adultos y niños. Partiendo de este contexto, se exploran y ejemplifican las diversas formas en que las corporaciones pueden cometer tráfico infantil. El artículo repasa brevemente la respuesta de los instrumentos internacionales y europeos en lo tocante a la responsabilidad penal de las corporaciones por la trata infantil, y aborda los mecanismos adoptados por algunas empresas para prevenir la trata y promover la transparencia en sus cadenas de suministro. En suma, se pretende ilustrar el rol crucial de las corporaciones desde dos puntos de vista: como potenciales perpetradores de este grave crimen y como actores necesarios

    Little is known whether differences exist in motivation and reactive/instrumental offense behaviors between murder offenders with and without psychotic disorder. To contribute to better prevention strategies, the aim of this study was to investigate offense characteristics in murder offenders with a psychotic, nonpsychotic or no psychiatric diagnosis, and whether these factors differ according to sex. This data study examined the population of murder offenders between 1997 and 2005 ( N = 435) in Victoria, Australia. Apparent motive for murder was allocated to one of six classifications. Assignations of reactive versus instrumental offense categories, co-offending, victim-offender relationship were determined by review of case material. Mental health service usage and prevalence of mental illnesses were identified through data with the statewide register of contacts with the public mental health system. Of the 435 offenders, 43 (9.9%) had been diagnosed with a psychotic illness. Gender differences between and within offenders with and without a psychotic disorder were analyzed. Murder offenders with a psychotic disorder were 3.19 (95% confidence interval [CI] = [1.27, 8.03]) times more likely to be motivated by revenge than nonpsychotic offenders and those with no diagnosis (odds ratio [OR] = 2.46, 95% CI = [1.10, 5.53]). The diagnostic groups did not differ on premeditation of their offenses or prior convictions. Perpetrators with psychotic illness were significantly more likely to kill family members and others known to them. It appears that for the psychotic disorder group, the perception of having been wronged in some way is a potential risk marker for planning and committing a serious offense. Care should be taken to improve adherence and access to care to avoid possible future serious violence especially in female patients with a high burden of mental illness like schizophrenia or severe mood disorders.

Venetoclax moderately inhibited P-gp, BCRP, OATP1B1, OATP1B3, CYP3A4, and CYP2C19, whereas CYP2B6 activity was increased. Venetoclax induced the mRNA expression of CYP1A1, CYP1A2, UGT1A3, and UGT1A9. In contrast, expression of ABCB1 was suppressed, which might revert tumor resistance towards antineoplastic P-gp substrates. P-gp over-expression led to reduced antiproliferative effects of venetoclax. Effective concentrations for inhibition and induction lay in the range of maximum plasma concentrations of venetoclax, indicating that it might act as a perpetrator drug in pharmacokinetic drug–drug interactions.

    Purpose Addressing gender norms is integral to understanding and ultimately preventing violence in both adolescent and adult intimate relationships. Males are affected by gender role expectations which require them to demonstrate attributes of strength, toughness, and dominance. Discrepancy stress is a form of gender role stress that occurs when boys and men fail to live up to the traditional gender norms set by society. Failure to live up to these gender role expectations may precipitate this experience of psychological distress in some males which, in turn, may increase the risk to engage in physically and sexually violent behaviors as a means of demonstrating masculinity. Methods Five-hundred eighty-nine adolescent males from schools in Wayne County, Michigan completed a survey assessing self-perceptions of gender role discrepancy, the experience of discrepancy stress, and history of physical and sexual dating violence. Results Logistic regression analyses indicated boys who endorsed gender role discrepancy and associated discrepancy stress were generally at greater risk to engage in acts of sexual violence but not necessarily physical violence. Conclusions Boys who experience stress about being perceived as “sub-masculine” may be more likely to engage in sexual violence as a means of demonstrating their masculinity to self and/or others and thwarting potential “threats” to their masculinity by dating partners. Efforts to prevent sexual violence perpetration among male adolescents should perhaps consider the influence of gender socialization in this population and include efforts to reduce distress about masculine socialization in primary prevention strategies.

    Reference scenarios for the JT-60SA tokamak have been simulated with one-dimensional transport codes to assess the stationary state of the flat-top phase and provide a profile database for further physics studies (e.g. MHD stability, gyrokinetic analysis) and diagnostics design. The types of scenario considered vary from pulsed standard H-mode to advanced non-inductive steady-state plasmas. In this paper we present the results obtained with the ASTRA, CRONOS, JINTRAC and TOPICS codes equipped with the Bohm/gyro-Bohm, CDBM and GLF23 transport models. The scenarios analysed here are: a standard ELMy H-mode, a hybrid scenario and a non-inductive steady state plasma, with operational parameters from the JT-60SA research plan. Several simulations of the scenarios under consideration have been performed with the above mentioned codes and transport models. The results from the different codes are in broad agreement and the main plasma parameters generally agree well with the zero dimensional estimates reported previously. The sensitivity of the results to different transport models and, in some cases, to the ELM/pedestal model has been investigated.

    NH3 is a degradation product of SA9T, a solid-amine sorbent developed by Hamilton Sundstrand, that is continually emitted into the gas stream being conditioned by this sorbent. NH3 offgassing rates were measured using FTIR spectroscopy using a packed bed at similar contact times as offgassing tests conducted at Hamilton Sundstrand and at the Ames Research Center. The bed was challenged with moist air at several flow rates and humidities and NH3 concentration of the effluent was measured for several hours. The NH3 offgassing rates in open-loop testing were calculated from the steady state outlet NH3 concentration and flow rate. NH3 offgassing rates from SA9T were found to be influenced by the contact time with the adsorbent (flow rate) and by the humidity of the inlet gas stream, which are consistent with previous studies. Closed-loop vacuum-swing adsorption cycling rates verified that NH3 offgassing continues when a constant source of water vapor is present.

    An objective assessment of speech would benefit the prosthetic rehabilitation of maxillectomy patients. This study aimed to establish a simple, objective evaluation of monosyllable /sa/ utterances in maxillectomy patients by using a psychoacoustic system typically used in industry. This study comprised two experiments. Experiment 1 involved analysis of the psychoacoustic parameters (loudness, sharpness and roughness) in monosyllable /sa/ utterances by 18 healthy subjects (9 males, 9 females). The utterances were recorded in a sound-treated room. The coefficient of variation (CV) for each parameter was compared to identify the most suitable parameter for objective evaluation of speech. Experiment 2 involved analysis of /sa/ utterances by 18 maxillectomy patients (9 males, 9 females) with and without prosthesis, and comparisons of the psychoacoustic data between the healthy subjects and maxillectomy patients without prosthesis, between the maxillectomy patients with and without prosthesis, and between the healthy subjects and maxillectomy patients with prosthesis. The CV for sharpness was the lowest among the three psychoacoustic parameters in both the healthy males and females. There were significant differences in the sharpness of /sa/ between the healthy subjects and the maxillectomy patients without prosthesis (but not with prosthesis), and between the maxillectomy patients with and without prosthesis. We found that the psychoacoustic parameters typically adopted in industrial research could also be applied to evaluate the psychoacoustics of the monosyllable /sa/ utterance, and distinguished the monosyllable /sa/ in maxillectomy patients with an obturator from that without an obturator using the system.

    Homicide-suicides, the murder of one or several individuals followed by the suicide of the perpetrator, are rare but have devastating effects on families and communities. We did a systematic review and meta-analysis of studies comparing perpetrators of homicide-suicides with perpetrators of simple homicides and suicides and examined the proportion of firearm use and its correlation with firearm availability. We searched Medline and Embase from inception to July 2012 and identified 27 eligible studies. Perpetrators of homicide-suicides were older and more likely to be male and married to or separated from their victims than perpetrator of simple homicides or suicides. Influence of alcohol and a history of domestic violence or unemployment were less prevalent in homicide-suicides than in homicides. The proportion of firearm use in homicide-suicides varied across countries and was highest in the USA, Switzerland and South Africa, followed by Australia, Canada, The Netherlands and England and Wales, with a strong correlation between the use of firearms and the level of civilian gun ownership in the country. Our results indicate that homicide-suicides represent a distinct entity, with characteristics distinguishing them both from homicides and suicides. Copyright © 2013 Elsevier Ireland Ltd.

    JT-60U modification program to fully superconducting device has been proceeded, namely ''JT-60SA'', toward early realization of fusion energy based on tokamak concept. The design of JT-60SA cryostat is expected to achieve a vacuum thermal insulation for super conducting coils, a bio-shielding boundary and structural gravity support. The cryostat is required to cover JT-60SA tokamak device, which is 15 m of total height and 7 m of radius, but there is geometrical limit due to surrounding devices reutilized. Although the cryostat consists of vessel body and gravity support, and the structural material is low cobalt 304 stainless steel (Co: 2 , and the design of the leaf spring is considered to reduce thermal stress, and to withstand the mechanical loads of plasma disruption and seismic loads. The coolant is 80 K gas helium and both sides of panel are covered with multi-layers super insulation (SI) to reduce heat load (radiation) up to 1/100. Fraction of non-covered region is assumed to be 2% due to many port-joints and supports for the vacuum vessel. Total heat load for inner surface of cryostat (600 m 2 ) is 9kW and the heat load for the port-joints (-300 m 2 ) is assumed up to 9 kW. The operational pressure of the cryostat is required to keep less than 10 -2 Pa and about 100,000 m 2 of structural surfaces is considered for exhaust system specification. Another role of the cryostat is the radiation protection. Biological shielding up to 10 micro-Sv/h (for maintenance acceptance) is required of the cryostat surface after the 10 years operation. Thus the cryostat consists of boron (2 wt%) doped concrete of 220 mm thickness and structural SS304 of total 40 mm thickness. The concrete reduces the air activation (41Ar) in the torus hall by 90% rather than the normal one by the thermal neutron absorption of boron. (orig.)

    In this mixed methods study, we explored how gender of an aggressor and the levels of aggression (i.e., yelling, throwing a drink, slapping, and punching) influenced attitudes about (a) public displays of intimate partner violence (IPV) and (b) bystander intervention. A feminist-informed, social constructionist perspective guided the study. Participants ( N = 562) responded online to randomly assigned factorial vignettes. Participants ranged in age between 18 and 70 years. The majority were female, self-identified as heterosexual, and identified as White. Logistic regressions revealed that participants significantly viewed aggression as unacceptable, especially in cases of more severe and male-perpetrated aggressions. Multinomial logistic regressions revealed that participants significantly thought bystanders or friends of the couple should intervene, especially in cases of male-perpetrated and/or more severe aggression. Analyses of qualitative responses indicated that participants viewed aggression as never okay, as poor communication, as justified if provoked, and discussed the gendered double standard of aggression (i.e., men should not be aggressive because they could cause more harm than females and female-perpetrated aggression is minor, in comparison). Regarding attitudes about bystander intervention, analyses of qualitative responses indicated that aggression severity, issues surrounding relationship privacy, factors relevant to the situation (e.g., if the event occurred once or repeatedly), perceptions that help was needed (e.g., if the victim was hurt), and the bystander's relationship with the victim (i.e., friend or not) were important to consider when thinking about the decision to intervene in public acts of violence. These findings have implications for bystander intervention programs and for how individuals view public acts of IPV.

    Cyberbullying victimization and perpetration continues to be a serious public health, criminal justice, victimology, and educational problem in middle schools in the United States. Adolescents are at a higher risk of experiencing cyberbullying as a victim and/or as a bully given the frequency of their use of the Internet via social networking sites such as Facebook and mobile devices such as cell phones and tablets. To address this important problem, the purpose of this investigation was to examine cyberbullying victimization through communication technology as a predictor of cyberbullying perpetration, body image, healthy eating and dieting behaviors, and life satisfaction of sixth-, seventh-, and eighth-grade-level middle school students. The World Health Organization recruited participants by using a Health Behavior in School-Aged Children (HBSC) survey. In this in-class questionnaire, 6,944 middle school students were asked about their cyberbullying experiences as a victim and as a bully via Internet, email, and mobile communication technologies to obtain their evaluations of their body image, eating and dieting habits, and perceptions of life satisfaction. After controlling for demographic factors such as sex, age, and class level, this study found that cyberbullying victimization was a predictor of cyberbullying perpetration, body image dissatisfaction, dieting behaviors, and life satisfaction. However, this study did not find a correlation between cyberbullying victimization and students' healthy eating behaviors. This study also discussed each of the findings in the context of previous research findings. In addition, the study provides the strengths, limitations, and future directions for the future examination of cyberbullying victimization in middle schools.

    To identify the prevalence and perpetrators of workplace violence against nurses and to examine the relationship of work demands and trust and justice in the workplace with the occurrence of violence. This study employed cross-sectional data from a 2013 nurse survey conducted at a university hospital in Seoul, South Korea. The study sample included 970 female nurses from 47 nursing units, including general, oncology, intensive care units (ICUs), operating rooms, and outpatient departments. The second version of the medium-sized Copenhagen Psychosocial Questionnaire (COPSOQ II) was used to measure work demands (i.e., quantitative demands, work pace, and emotional demands), trust and justice, and violence. Relationships among those variables were examined by conducting multiple logistic regression analyses with multilevel modeling. The 12-month prevalence of verbal abuse (63.8%) was highest, followed by threats of violence (41.6%), physical violence (22.3%), and sexual harassment (19.7%), but bullying had the lowest prevalence (9.7%). Physical violence, threats of violence, and verbal abuse occurred most frequently in ICUs, whereas sexual harassment and bullying were highest in operating rooms. The main perpetrators were patients, followed by physicians and patients' families. Nurses perceiving greater work demands and less trust and justice were more likely to have been exposed to violence. The prevalence and perpetrators of violence varied considerably among nursing units. Greater work demands and less trust and justice were associated with nurses' experiences of violence. Adequate work demands and a trusted and just work environment may reduce violence against nurses. In return, reduction of violence will contribute to creating a better nursing work environment. © 2014 Sigma Theta Tau International.

    We aimed to examine the influence of witnessing father-to-mother violence on: 1) perpetration of intimate partner violence (IPV); and 2) endorsement of attitudes justifying wife beating in Bangladesh. This paper used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 3374 ever-married men. Exposure to IPV was determined by men's self-reports of witnessing inter-parental violence in childhood. We used adjusted binary logistic regression models to assess the influence of exposure on husbands' perpetration of IPV and their endorsement of attitudes justifying wife beating. Nearly 60% of men reported violent behaviour towards an intimate partner and 35.7% endorsed attitudes justifying spousal abuse. Men who witnessed father-to-mother violence had higher odds of reporting any physical or sexual IPV (adjusted OR [AOR] = 3.26; 95% CI = 2.61, 4.06). Men who had witnessed father-to-mother violence were also 1.34 times (95% CI = 1.08, 1.65) more likely endorse attitudes justifying spousal abuse. Committing violence against an intimate partner is an all too frequent practice among men in Bangladesh. The study indicated that men who had witnessed father-to-mother violence were more likley to perpetrate IPV, suggesting an intergenerational transmission of violence. This transmission of violence may operate through the learning and modelling of attitudes favourable to spousal abuse. In support of this, witnnessing inter-parental violence was also associated with the endorsement of attitudes justifying spousal abuse. Our findings indicate the continued importance of efforts to identify and assist boys who have witnessed domestic violence and suggest such efforts should aim to change not just behaviours but also attitudes that facilitate such violence.

    This study experimentally examines the effects of participant sex, perpetrator sex, and severity of violence on perceptions of intimate partner violence (IPV) seriousness, sympathy toward the victim, and punishment preferences for the perpetrator. Participants (N = 449) were randomly assigned to a condition, exposed to a composite news story, and then completed a survey. Ratings of seriousness of IPV for stories with male perpetrators were significantly higher than ratings of seriousness for stories with female perpetrators. Men had significantly higher sympathy for female victims in any condition than for male victims in the weak or strong severity of violence conditions. Men's sympathy for male victims in the fatal severity of violence condition did not differ from their sympathy for female victims. Women had the least sympathy for female victims in the weak severity condition and men in the weak or strong severity conditions. Women reported significantly higher sympathy for female victims in the strong and fatal severity of violence conditions. Women's ratings of sympathy for male victims in the fatal severity of violence condition were statistically indistinguishable from any other group. Participants reported stronger punishment preferences for male perpetrators and this effect was magnified among men. Theoretical implications are presented with attention provided to practical considerations about support for public health services.

    This paper describes the preliminary criteria, which are intended to be used by the South African regulatory authority (CNS), for licensing of the ESKOM proposed - South African high temperature gas-cooled Pebble Bed Modular Reactor (PBMR-SA). The CNS intends to apply the existing CNS licensing approach together with some international design criteria used for advanced reactors as well as international experience gained from the safety evaluation of the MHTGR, THTR, etc. A major requirement to this type of reactor is that it should comply with the current CNS risk criteria and provide, as a minimum, the same degree of protection to the operator, public and environment that is required for the current generation of nuclear reactors.

    The stars in four fields of the Basle Halo Program (BHP), henceforth called "UBV-fields", had been (photographically) observed in RGU and in UBV, in order to treat their data in both photometric systems with the same stellar-statistical method for the determination of space density gradients, developed by Becker (1%5) for the RGU-fields of the BHP The purpose was to compare the corresponding results in both systems and to obtain an idea about their mutual performance with respect to this method. All four investigations (references in Tab. I) proved it to work about equally well in both systems, if the outcome is measured in terms of a relatively rough criterion, the so-called "mean misidentification-rate per system" (MMRS). In order to obtain a better founded view about the degree of equivalence of both systems with respect to their application for the three-colour photometrical purposes of the Basle programs, we decided to treat the UBV-fields in this third contribution to the present model-comparison synopsis, in RGU and in UBV, too, by comparing the total space densities observed in both systems with the five standard model gradients and according to the comparison method homogeneously used within the "comparison-phase" of the BHP which was initiated by del Rio and Fenkart (1987). In the appendix, as in paper I, the first contribution to this synopsis (Fenkart, 1989a), we give a full description of the comparison method, and the definition of the five standard models for the space density distribution in the Galaxy which are essentially three versions of the Bahcall-Soneira (1980) two-component model.

    Full Text Available Esta pesquisa teve como objetivo desvelar o conhecimento dos formandos dos cursos de Enfermagem e Medicina de uma Universidade do Rio Grande do Sul acerca da promoção da Saúde Oral. Participaram do estudo 58 acadêmicos, sendo 26 do Curso de Enfermagem e 32 do Curso de Medicina, estes responderam a um questionário com três perguntas semi-estruturadas. Através da triangulação constatamos que esse conhecimento entre os formandos dos referidos cursos é deficitário. Sabemos que é grande a dificuldade de acesso da população infantil carente aos gabinetes dentários, por esse motivo, acreditamos ser indispensável que os profissionais de Enfermagem e Medicina tenham conhecimentos referentes à promoção de saúde oral em crianças.

    Full Text Available Background. Appropriate critical care admissions are an important component of surgical care. However, there are few data describing postoperative critical care admission in resource-limited low- and middle-income countries. Objective. To describe the demographics, organ failures, organ support and outcomes of non-cardiac surgical patients admitted to critical care units in South Africa (SA. Methods. The SA Surgical Outcomes Study (SASOS was a 7-day national, multicentre, prospective, observational cohort study of all patients ≥16 years of age undergoing inpatient non-cardiac surgery between 19 and 26 May 2014 at 50 government-funded hospitals. All patients admitted to critical care units during this study were included for analysis. Results. Of the 3 927 SASOS patients, 255 (6.5% were admitted to critical care units; of these admissions, 144 (56.5% were planned, and 111 (43.5% unplanned. The incidence of confirmed or strongly suspected infection at the time of admission was 35.4%, with a significantly higher incidence in unplanned admissions (49.1 v. 24.8%, p<0.001. Unplanned admission cases were more frequently hypovolaemic, had septic shock, and required significantly more inotropic, ventilatory and renal support in the first 48 hours after admission. Overall mortality was 22.4%, with unplanned admissions having a significantly longer critical care length of stay and overall mortality (33.3 v. 13.9%, p<0.001. Conclusion. The outcome of patients admitted to public sector critical care units in SA is strongly associated with unplanned admissions. Adequate ‘high care-dependency units’ for postoperative care of elective surgical patients could potentially decrease the burden on critical care resources in SA by 23%.

    Full Text Available OBJETIVO: O artigo analisa a participação do gasto privado com saúde das famílias no PIB e no total da renda familiar per capita e a distribuição do gasto privado com saúde das famílias por classes de renda. MÉTODOS: A pesquisa utilizou os microdados da Pesquisa Nacional por Amostra de Domicílios de 1998, com a divisão da população em quatro classes de renda familiar per capita e a distribuição dos gastos em planos de saúde, consultas médicas, consultas com outros profissionais de saúde, exames, medicamentos, artigos ortopédicos e aparelhos médicos, óculos e lentes, odontologia, hospitais, enfermagem domiciliar e outros gastos com saúde. RESULTADOS: Apenas 7,2% da população com renda familiar per capita até 1 salário mínimo em 1998 tinha direito a algum plano de saúde, e o gasto privado com saúde das famílias desta classe, que representava 52,5% da população, era em média de R$ 5,36 por pessoa. Para as pessoas com renda familiar per capita acima de 9 salários mínimos, os planos de saúde atingiam 83,2% da população e o gasto privado com saúde das famílias R$ 133,04. CONCLUSÕES: A implantação do Sistema Único de Saúde foi acompanhada pelo crescimento expressivo dos planos de saúde nos anos 90. Mesmo se todo o gasto público com saúde fosse destinado à população sem planos de saúde, ainda assim o gasto destas pessoas em 1998 só alcançaria R$ 352,62, ou seja, 43% do gasto com saúde das pessoas com planos, R$ 819,08.

  16. Em busca de uma Teologia Pública da Saúde

    2016-03-01

    Full Text Available A proposta de uma teologia pública da saúde visa o diálogo entre antropologia teológica e antropologias médicas e da saúde de modo a ampliar a percepção da saúde, não somente como fato, mas como valor. Mesmo um Estado Laico, suas tradições religiosas possuem hermenêuticas de saúde, ao interpretar a doença e a morte com razões religiosas distintas, ora conflitantes, ora cooperativas com as ciências da saúde. Ampliar essas hermenêuticas religiosas compondo a sabedoria de vida presente nas expressões religiosas e o conhecimento científico da área de saúde visa uma cooperação para interesses de bem comum da sociedade civil, como é a questão da saúde. Para essa reflexão, a escola de Cós combina a sabedoria mítica asclepíade e a ciência jônia. Os mitos de saúde nomeados no juramento hipocrático pertencem à tradição da teologia poética grega e indica uma espécie de credo no qual a medicina hipocrática professa, no qual o médico além de profissional também possui fé na vida e exerce o ofício de sacerdote da esperança. Interessa ainda o modo como o a teologia da saúde grega foi recebida pela teologia cristã, e como ambas desconstruíram suas teodiceias. Nessa recepção há um caminho para pensar uma teologia pública da saúde.

    Based on ibrutinib pharmacokinetics and potential sensitivity towards CYP3A4-mediated drug-drug interactions (DDIs), a physiologically based pharmacokinetic approach was developed to mechanistically describe DDI with various CYP3A4 perpetrators in healthy men under fasting conditions. These models were verified using clinical data for ketoconazole (strong CYP3A4 inhibitor) and used to prospectively predict and confirm the inducing effect of rifampin (strong CYP3A4 inducer); DDIs with mild (fluvoxamine, azithromycin) and moderate inhibitors (diltiazem, voriconazole, clarithromycin, itraconazole, erythromycin), and moderate (efavirenz) and strong CYP3A4 inducers (carbamazepine), were also predicted. Ketoconazole increased ibrutinib area under the curve (AUC) by 24-fold, while rifampin decreased ibrutinib AUC by 10-fold; coadministration of ibrutinib with strong inhibitors or inducers should be avoided. The ibrutinib dose should be reduced to 140 mg (quarter of maximal prescribed dose) when coadministered with moderate CYP3A4 inhibitors so that exposures remain within observed ranges at therapeutic doses. Thus, dose recommendations for CYP3A4 perpetrator use during ibrutinib treatment were developed and approved for labeling. © 2016 American Society for Clinical Pharmacology and Therapeutics.

    ABSTRACT In recent years a growing amount of research has been conducted in the area of workplace incivility. Whereas many studies have focused on the victims and the consequences of incivility, little attention has been paid to the perpetrators and antecedents of workplace incivility. This study aims to identify possible antecedents of workplace incivility, by investigating organizational aspects as well as the possibility that being the target of incivility from co-workers and supervisors could induce incivility. A total of 512 employees (378 women and 133 men) in the school sector in a Swedish municipality completed an online questionnaire. Overall, the results of structural equation modelling analyses showed that organizational variables were related to the perpetration of incivility. A direct relationship was found between being uncivil and organizational change, job insecurity, low social support from co-workers and high job demands. However, the strongest relationship was found between experienced incivility from co-workers and instigated incivility. This could be reflecting a climate or culture of incivility in the organization, and carry implications for future practice in interventions against workplace incivility. The results indicate the importance of focusing on the perspective of the instigator to gain knowledge about the process of workplace incivility. PMID:27226677

    Studies report that alcohol use is related to partner violence, but for many, alcohol use does not culminate in violence against partners. Guided by a self-regulatory failure framework, we predicted that alcohol use would be more strongly associated with dating violence perpetration among adolescents with genotypes linked to impulsivity and emotional reactivity. The hypothesis was tested using random coefficient modeling of data from a multi-wave longitudinal study spanning grades 8-12 (ages 13-18) (n = 1,475). Analyses adjusted for multiple testing and race, and the potential for gene by environment correlation was examined. As predicted, alcohol use was more strongly associated with dating violence among adolescents who had a high rather than a low multilocus genetic profile composed of five genetic markers that influence dopamine signaling. Alcohol use was more strongly related to dating violence among boys with long rather than short 5-HTTLPR alleles, the opposite of the prediction. MAOA-uVNTR did not interact with alcohol, but it had a main effect on dating violence by boys in later grades in the expected direction: boys with more low activity alleles perpetrated more dating violence. Exploratory analyses found variation in findings by race. Our findings demonstrate the importance of incorporating genes into etiological studies of adolescent dating violence, which to date has not been done. Aggr. Behav. Aggr.

    Child peer violence is a global problem and seriously impacts health and education. There are few research studies available in Pakistan, or South Asia. We describe the prevalence of peer violence, associations, and pathways between socio-economic status, school performance, gender attitudes and violence at home. 1752 children were recruited into a cluster randomized controlled trial conducted on 40 fairly homogeneous public schools (20 for girls and 20 for boys), in Hyderabad, Pakistan. This was ranging from 20-65 children per school. All children were interviewed with questionnaires at baseline. Few children had no experience of peer violence in the previous 4 weeks (21.7% of girls vs.7% of boys). Some were victims (28.6%, of girls vs. 17.9% of boys), some only perpetrated (3.3% of girls vs. 2.5%) but mostly they perpetrated and were victims (46.4%.of girls vs 72.6%. of boys). The girls' multivariable models showed that missing the last school day due to work, witnessing her father fight a man in the last month and having more patriarchal gender attitudes were associated with both experiencing violence and perpetration, while, hunger was associated with perpetration only. For boys, missing two or more days of school in the last month, poorer school performance and more patriarchal attitudes were associated with both victimization and perpetration. Witnessing father fight, was associated with peer violence perpetration for boys. These findings are additionally confirmed with structural models. Peer violence in Pakistan is rooted in poverty and socialization of children, especially at home. A critical question is whether a school-based intervention can empower children to reduce their violence engagement in the context of poverty and social norms supportive of violence. In the political context of Pakistan, reducing all violence is essential and understanding the potential of schools as a platform for intervention is key.

    Young men's involvement in fathering pregnancies has been substantially neglected in unintended pregnancy research. Gender norms give men substantial power and control over sexual encounters, suggesting that understanding men's role is imperative. We tested the hypothesis that young, unmarried South African men who had perpetrated intimate partner violence (IPV) have a greater incidence of fathering pregnancies. The data for this study were collected from 983 men aged 15 to 26 who participated in a 2-year community randomized controlled HIV prevention trial in the rural Eastern Cape. Multivariate Poisson models investigated the associations between baseline perpetration of IPV and fathering subsequent pregnancies, while controlling for age, number of sexual partners, socio-economic status, educational attainment, problematic alcohol use, exposure to the intervention, and time between interviews. Of the men in this study, 16.5% (n = 189) had made a girlfriend pregnant over two years of follow up. In addition, 39.1% had perpetrated physical or sexual intimate partner violence and 24.3% had done so more than once. Men who at baseline had perpetrated IPV in the previous year had an increased incidence of fathering, for a first perpetration in that year IRR 1.67 (95% CI 1.14-2.44) and among those who had also been previously violent, IRR 1.97 (95% CI 1.31-2.94). Those who had ever been violent, but not in the past year, did not have an elevated incidence. The incidence among men who had ever perpetrated physical abuse was less elevated than among those who had perpetrated physical and sexual violence IRR 1.64 (95% CI 1.18-2.29) versus IRR 2.59 (95% CI 1.64-4.10) indicating a dose response. Young men's perpetration of partner violence is an important predictor of subsequently fathering a pregnancy. The explanation may lie with South African hegemonic masculinity, which valorizes control of women and displays of heterosexuality and virility, and compromises women

    SAFARI-1 (South African Fundamental Atomic Research Installation), the first nuclear reactor of any significance in Africa, situated at Pelindaba, commemorates 20 years of existence this year. In 1957 the Atomic Energy Board intended to purchase a research reactor with a capacity of 5MW. The intension was to use the reactor to provide training and experience for a second phase. This phase involved the design and construction of a more advanced type of reactor with an average flux at least 10 14 neutrons/M 2 /SEC. It became possible to combine these two phases by installing a high-flux materials testing reactor. The scheduled completion of the SAFARI-1 project was delayed by a rare accident at the contractor's workshop in the USA. In March 1965 the first fuel elements were loaded. In 1969 the power was successfully raised to 20MW. After a fuel embargo S.A. developed its own medium-enriched fuel for SAFARI-1. The uses of SAFARI-1 reactor have branced off into many fields, notably the applications of radioactive isotopes, for nuclear medicine, agriculture, research and industry, and radiation. The way in which neutrons act on matter makes it possible to obtain information that cannot be obtained by other types of radiation. Neutron activation analysis techniques is also used to identify some elements in materials. Radiotracers, manufactured in SAFARI-1, is used in particular, to solve certain industrial problems

    Full Text Available Dentro de alguns poucos anos, nosso planeta contará com mais habitantes em áreas urbanas do que em áreas rurais. A urbanização desenfreada, sem mecanismos regulatórios e de controle, típica dos países periféricos, trouxe consigo enormes repercussões na saúde da população. Problemas como a insuficiência dos serviços básicos de saneamento, coleta e destinação adequada do lixo e condições precárias de moradia, tradicionalmente relacionados com a pobreza e o subdesenvolvimento, somam-se agora à poluição química e física do ar, da água e da terra, problemas ambientais antes considerados "modernos". Novamente, é sobre as populações mais carentes que recai a maior parte dos efeitos negativos da urbanização, gerando uma situação de extrema desigualdade e iniqüidade ambiental e em saúde. Para reverter esse quadro é preciso que haja uma reincorporação das questões do meio ambiente nas políticas de saúde, e a integração dos objetivos da saúde ambiental numa ampla estratégia de desenvolvimento sustentável. Uma abordagem mais integrada, com mecanismos intersetoriais que possibilitem um diálogo amplo entre as partes, trará enormes benefícios na conquista de melhores condições de vida nas cidades. A saúde ambiental hoje tem o desafio de promover uma melhor qualidade de vida e saúde nas cidades e a oportunidade de enfrentar o absurdo quadro de exclusão social, sob a perspectiva da eqüidade.In a matter of few years there will be more urban than rural dwellers worldwide.

  7. What Do Parents Attribute the Cause of Bullying to? It Can Amplify or Buffer the Vicious Cycle of Bullying Perpetration and Victimization.

    Science.gov (United States)

    Choi, Boungho; Park, Soowon

    2018-05-01

    The purpose of this study is to examine what do parents attribute the causes of bullying to and how the attributions of parents are related with their adolescents' experiences of bullying perpetration and bullying victimization in the subsequent year. The data were drawn from 3,293 Korean secondary students and their parents from the Seoul Education Longitudinal Study across two waves (seventh, eighth grades). The results revealed that 1,228 (37.3%) parents thought that bullying was caused by perpetrators' faults while 512 (15.5%) parents thought bullying was caused by victims' faults. The other 1,553 (47.2%) showed external attributions (e.g., peer, violent media). Adolescents' bullying perpetration and victimization interacted with parent's attribution in predicting later bullying perpetration and victimization. These results indicate that parent's attribution is a critical factor to understanding the alleviation or deterioration of bullying in adolescents. Intervention programs should be designed to concern parents' attribution as well as adolescents' prior bullying experiences.

    Using data from the International Dating Violence Study, this study examined the roles of early socialization, family social structure, and relationship dynamics factors on physical aggression in dating among U.S. college students in emerging adulthood. The interaction effects between these three domains of interest (early socialization, family social structure, and relationship dynamics) were explored to understand the underlying mechanisms that influenced victimization and perpetration in dating. In general, we found that family and relational variables associated with dating victimization and perpetration were fairly similar. Among the early socialization variables, experience of childhood neglect and having witnessed domestic violence were significantly related to victimization and perpetration. Living in a two-parent household appeared to exert a protective effect, although associations with parental education were not statistically significant. Furthermore, the participants were more likely to experience victimization or impose aggression in dating relationships which were characterized by conflicts, distress, dominance, or psychological aggression. Overall, for the participants who came from a two-parent household, dominance in dating was linked to less violence. When the participants faced higher levels of psychological aggression, adverse early socialization factors were associated with higher levels of dating violence victimization and perpetration. Research and practice implications were discussed. © The Author(s) 2016.

    Full Text Available Perpetrator images are those that are part of the machinery of destruction (torture, genocide…. This means that in them the act of violence and the apparatus of image production are interpenetrated. However, this condition does not predetermine the degree of personal, temporal, spatial implication between the two processes. And, in fact, several kinds of hiatuses may occur. The objective of this text is to analyse the production and migration of a perpetrator image-icon associated with the Cambodian genocide (the image of Hout Bophana. First, the article focuses on the process of (pragmatic creation of this mug shot that identifies the detainee, emphasising her identity. Then, we study the use, re-appropriation, insertion, détournement of the same image in two films directed by Rithy Panh: Bophana, une tragédie combodgienne (1996 and Duch, le maître des forges de l’enfer (2011. In this proposed itinerary, we move from the creation of a performative image (the one that produces an enemy, instead of simply registering him to its confrontation with the perpetrator (the Tuol Sleng’s director, Duch responsible for its execution. In so doing, we draw attention to the pictorial and cinematic re-elaboration of the counter-figure, the reverse shot, of that perpetrator image: Bophana portrait as it was painted by the survivor Vann Nath.

    2002-01-01

    Full Text Available Esse artigo estuda a relação entre desigualdade social e saúde no Brasil. A estratégia usada foi avaliar as necessidades e o consumo dos serviços de saúde, bem como o acesso a seguro saúde ao longo da distribuição de renda. Adicionalmente, por meio da estimação de uma regressão logística, foram avaliados outros determinantes do consumo dos serviços de saúde, com o intuito de se conhecer aonde e quem utiliza esses serviços no país. Os dados foram extraídos da Pesquisas Nacional de Amostra por Domicilio da Fundação Instituto Brasileiro de Geografia e Estatística levada a campo em 1998. Em geral, observou-se que os indivíduos nos primeiros décimos da distribuição de renda têm pior acesso a seguro saúde, necessitam de maiores cuidados médicos, mas consomem menos os serviços de saúde. As outras características extra rendimento indicam que os principais determinantes para o consumo dos serviços de saúde estariam fortemente associados aos grupos sociais mais privilegiados (de maior escolaridade, acesso a seguro saúde, água, esgoto, luz, coleta de lixo e a fatores que apontam para capacidade de geração de oferta desses serviços no país.

  20. What looks like sexism and why? The effect of comment type and perpetrator type on women's perceptions of sexism.

    Science.gov (United States)

    Riemer, Abigail; Chaudoir, Stephenie; Earnshaw, Valerie

    2014-01-01

    Sexist comments are not perceived equally in the eyes of women. We extend previous research by examining the degree to which multiple types of potentially sexist comments made by multiple types of men are perceived as sexist. Further, we examine the degree to which three possible mediators--prototypicality, perceived intent, and interdependence--explained these effects. Female undergraduate students (N = 248) were randomly assigned to read a scenario in which a hostile sexist, benevolent sexist, or objectifying comment was made by one of three types of men: a stranger, their boss, or their boyfriend. Results demonstrate that hostile sexism was perceived as more sexist than benevolent sexism or objectification. Comments made by boyfriends were also rated as less sexist than those made by bosses or strangers. Furthermore, perceptions of prototypicality of the comment or perpetrator and perceived intent to harm mediated the effect of study manipulations on perceptions of sexism.

    2013-02-01

    The present research was designed to evaluate self-determination theory as a framework for integrating factors associated with intimate partner violence (IPV) perpetration. The proposed model suggests that childhood exposure to parental violence may influence global motivational orientations which, in turn result in greater cognitive biases (overestimating the prevalence of IPV and justification of IPV) which, in turn, contribute to an individual's decision to use abusive behavior. Participants included 124 men who had engaged in abusive behavior toward an intimate partner. Results provided reasonable support for the proposed model and stronger support for a revised model suggesting that controlled orientation, rather than autonomy orientation, appears to play a stronger role in the association between childhood exposure to parental violence and cognitive biases associated with abusive behavior.

    In this study, microstructure and mechanical properties of SA508 Gr.3 Cl. 1, Cl.2, and Gr.4N low alloy steels are characterized to compare their properties. To evaluate the fracture toughness in the transition region, the master curve method according to ASTM E1921 was adopted in the cleavage transition region. Tensile tests and Charpy impact tests were also performed to evaluate the mechanical properties, and a microstructural investigation was carried out. The microstructure and mechanical properties of SA508 Gr.3 Cl.1, Cl2 and Gr.4N low alloy steels were characterized.. The predominant microstructure of SA508 Gr.4N model alloy is tempered martensite, while SA508 Gr.3 Cl.1 and Cl.2 steels show a typical tempered upper bainitic structure. SA508 Gr. 4N model alloy shows the best strength and transition behavior among the three SA508 steels. SA508 Gr.3 Cl.2 steel also has quite good strength, but there is a loss of toughness.

    Japan Atomic Energy Agency started to construct a fully superconducting tokamak experiment device, JT-60SA, to support the ITER since January, 2013 at the Fusion Research and Development Directorate in Naka, Japan. The JT-60SA will be constructed with enhancing the previous JT-60 infrastructures, in the JT-60 torus hall, where the ex-JT-60 machine was disassembled. The JT-60SA Cryostat Base, for base of the entire tokamak structure, were assembly as the first step of this construction. The Cryostat Base (CB, 250tons) is consists of 7 main components made of stainless steel, in 12 m diameter and 3 m height. The CB was built in the Spain and transported to the Naka site, via Hitachi port. After pre-assembly work including preliminary measurements and sole plate adjustments of its height/flatness, the JT-60SA CB was carefully set on the sole plate. JT-60SA CB was assembled with high accuracy by using a laser tracker. The CB was adjusted in the height and flatness against the assembly reference position and determined by the absolute coordinates. This report introduces the concrete result of assembly work and transport of JT-60SA CB. (author)

    Full Text Available O presente artigo trata da relação entre a saúde dos idosos e relacionamentos sociais, bem como na interpretação e entendimento desta problemática sob a luz de dois enfoques teóricos: um macro, centrado na Teoria da Integração Social de Emile Durkheim e outro micro, centrado na Teoria das Trocas, de Peter Blau, com ênfase na Teoria da Eqüidade. A integração social (freqüência de contatos pode ter efeitos negativos na saúde, mas isto tem de ser medido pela qualidade dos contatos. Algumas conclusões apresentadas indicam que as relações sociais têm um efeito na saúde, no sentido de que as pessoas, nas sociedades modernas, esperam a reciprocidade, e, quando isto não é possível, principalmente na fase do envelhecimento, as pessoas sentem-se dependentes, e isso pode afetar a saúde de diferentes maneiras. Por outro lado, quando as pessoas têm problemas de saúde, elas experienciam uma falta de relações sociais balanceadas devido à incapacidade para trocar em bases iguais. Sendo assim, conclui-se que a relação entre relações sociais e saúde na população idosa pode ser uma relação recíproca.

    JT-60SA has been designed and is being constructed to demonstrate and develop steady-state high-beta operation. Resistive wall mode (RWM) control, error field correction, and edge-localized mode (ELM) control will be performed using in-vessel coils. For these controls, we have developed a biaxial magnetic sensor to determine 3D magnetic configuration of the plasma. Moreover, for obtaining basic information about JT-60SA plasma, magnetic sensors, in particular, one-turn loops, Rogowski coils, diamagnetic loops, and saddle coils have been developed. Because the length of the vacuum vessel in the poloidal direction of JT-60SA is 16 m and almost twice as long as that of JT-60U, the length of the Rogowski coil and the diamagnetic loop of JT-60SA are also twice as long as those on JT-60U. We have devised new types of sensors and a connector for the mineral-insulated cable because construction and installation of these sensors are much more difficult in JT-60SA. We will report the design and specification of the magnetic sensors for JT-60SA from the physics and engineering aspects.

  6. Automated analysis of calcium spiking profiles with CaSA software: two case studies from root-microbe symbioses.

    Repeated oscillations in intracellular calcium (Ca2+) concentration, known as Ca2+ spiking signals, have been described in plants for a limited number of cellular responses to biotic or abiotic stimuli and most notably the common symbiotic signaling pathway (CSSP) which mediates the recognition by their plant hosts of two endosymbiotic microbes, arbuscular mycorrhizal (AM) fungi and nitrogen fixing rhizobia. The detailed analysis of the complexity and variability of the Ca2+ spiking patterns which have been revealed in recent studies requires both extensive datasets and sophisticated statistical tools. As a contribution, we have developed automated Ca2+ spiking analysis (CaSA) software that performs i) automated peak detection, ii) statistical analyses based on the detected peaks, iii) autocorrelation analysis of peak-to-peak intervals to highlight major traits in the spiking pattern.We have evaluated CaSA in two experimental studies. In the first, CaSA highlighted unpredicted differences in the spiking patterns induced in Medicago truncatula root epidermal cells by exudates of the AM fungus Gigaspora margarita as a function of the phosphate concentration in the growth medium of both host and fungus. In the second study we compared the spiking patterns triggered by either AM fungal or rhizobial symbiotic signals. CaSA revealed the existence of different patterns in signal periodicity, which are thought to contribute to the so-called Ca2+ signature. We therefore propose CaSA as a useful tool for characterizing oscillatory biological phenomena such as Ca2+ spiking.

  7. Perpetration of Alcohol-Related Aggression by Male and Female College Students: An Examination of Overt and Relational Aggression.

    Existing literature exemplifies the relationship between alcohol and overt aggression, especially for adult males. Less clear is the relationship between alcohol and aggression among male and female college students, in particular, the nature of this aggression and the co-occurrence of drinking and aggression on the same day (temporal proximity). This study examines the chronic and temporal nature of males' and females' alcohol-related aggression among college students. Two hundred fourteen students completed a web-based 7-day event-level survey measuring alcohol consumption and perpetration of physical aggression, verbal aggression, anger, and relational aggression over 4 weeks, resulting in 4,256 observations (days). The global analysis revealed students who are heavy drinkers are more likely to perpetrate all four forms of aggression, whereas the event-level analysis revealed that specific forms of aggression are associated with drinking at the time, while other forms were not linked to drinking occasions. Cross-tabulation revealed males and females were more likely to use verbal and physical aggression when drinking. For females, drinking was also associated with relational aggression and anger. Despite often being overlooked in research on aggression during emerging adulthood, relational aggression was prevalent. Discrepancies between the global and temporal analysis revealed factors other than alcohol might explain the relationship between chronic alcohol consumption and specific forms of aggression. This is one of the first event-level studies to show the temporal relationship between alcohol and relational aggression. The distinctions in the current study, exemplifying the diversity of alcohol-related aggression, are critical for understanding aggressive behavior, potential gender differences, and for developing interventions. The temporal relationship between alcohol and aggression suggests health interventions should target drinking and aggression

    Full Text Available Abstract Background Over the past 30 years, intimate partner violence (IPV against women and its health consequences has become a well established research area and is recognized worldwide as a significant public health issue. Studies on IPV directed at men are less explored, however recently women’s use of IPV and men’s victimization is gaining growing attention. Earlier population-based studies performed in Sweden have primarily investigated men’s violence against women, while women’s use of violence and men’s exposure as well as the existence of controlling behaviours have been neglected research areas This explorative study investigated the exposure to and perpetration of intimate partner violence, the use of control behaviours and the associated risk factors among a sample of Swedish men and women. Methods This cross-sectional population-based study included 173 men and 251 women of age 18–65 randomly selected among the Swedish population. A questionnaire based on the revised Conflicts Tactics Scale (CTS2 and the subscale ‘isolating control’ from the Controlling Behaviour Scale (CBS was used to collect data on violence exposure and perpetration. Regression analyses were used for risk factor assessment. Results More men (11% than women (8% reported exposure to physical assault in the past year, while more women reported exposure to sexual coercion. Duration of present relationship ≤ 3 years was identified as a significant risk factor for men’s exposure. Young age, lack of social support and being single, constituted risk factors for women’s exposure. Surprisingly many men (37% and women (41% also reported exposure to controlling behaviours. Conclusions In partner violence research, both men’s and women’s exposure should be explored however findings need to be interpreted with caution. This first study in a Swedish sample establishes the basis for future investigations on partner violence and coercive control tactics.

    The high risk of perpetrating physical dating violence, bullying, and sexual harassment by adolescents exposed to domestic violence points to the need for programs to prevent these types of aggression among this group. This study of adolescents exposed to domestic violence examined whether these forms of aggression share risk factors that could be targeted for change in single programs designed to prevent all three types of aggression. Analyses were conducted on 399 mother victims of domestic violence and their adolescents, recruited through community advertising. The adolescents ranged in age from 12 to 16 years; 64 % were female. Generalized estimating equations was used to control for the covariation among the aggression types when testing for shared risk factors. Approximately 70 % of the adolescents reported perpetrating at least one of the three forms of aggression. In models examining one risk factor at a time, but controlling for demographics, adolescent acceptance of sexual violence, mother–adolescent discord, family conflict, low maternal monitoring, low mother–adolescent closeness, low family cohesion, depressed affect, feelings of anger, and anger reactivity were shared across all three aggression types. In multivariable models, which included all of the risk factors examined and the demographic variables, low maternal monitoring, depressed affect and anger reactivity remained significant shared risk factors. Our findings suggest that programs targeting these risk factors for change have the potential to prevent all three forms of aggression. In multivariable models, poor conflict management skills was a risk for bullying and sexual harassment, but not dating violence; acceptance of dating violence was a risk for dating violence and bullying, but not sexual harassment; and none of the examined risk factors were unique to aggression type. The study’s implications for the development of interventions and future research are discussed. PMID:26746242

    The aim of this meta-analysis was to identify the factors that related to aggression (verbal abuse or physical abuse/assault) perpetrated against the nurse or other health professionals by patients/relatives or staff. In the light of the paucity of systematic reviews on this common issue in nursing, the objective was to present a comprehensive systematic review and meta-analysis of these papers. Aggression towards nurses is common around the world and can be the impetus for nurses leaving the profession or developing anxiety when working in particular settings. Systematic review with meta-analysis. Meta-analyses were conducted to assess the effect of the factors of gender and context (dichotomised as mental health/psychiatric or nonmental health/psychiatric). The databases of Medline (1966-2015), CINAHL (1982-2015) and PsychInfo (1920-2015). A total of 1571 papers were screened by two reviewers. At the final decision 14 were selected for analysis. A higher proportion of female nurses than male nurses were reported to be the victims of verbal abuse, with the difference in proportions being statistically significant. A statistically significant higher proportion of male nurses than female nurses were reported to be the victims of physical abuse. There was a significantly higher proportion of mental health nurses reported experiencing physical abuse as compared to nonmental health nurses. The analysis reveal female nurses have greater odds of verbal abuse than male nurses and male nurses have greater odds of physical abuse than female nurses. Overall mental health nurses had three times higher odds of physical assault than other nurses. In the light of the findings it is recommended organisational support improve in high aggression potential clinical areas and for nursing curriculums to incorporate education about the management of challenging behaviours in undergraduate programmes. © 2015 John Wiley & Sons Ltd.

    Emerging research suggests significant positive associations between bullying and substance use behaviors. However, these studies typically focused either on the link between substance use and bullying perpetration or victimization, and few have conceptualized bullying perpetration and/or victimization as mediators. In this study, we simultaneously tested past bullying perpetration and victimization as mediational pathways from retrospective report of parenting styles and global self-esteem to current depressive symptoms, alcohol use and alcohol-related problems. Data were collected from a college sample of 419 drinkers. Mediation effects were conducted using a bias-corrected bootstrap technique in structural equation modeling. Two-path mediation analyses indicated that mother and father authoritativeness were protective against bully victimization and depression through higher self-esteem. Conversely, having a permissive or authoritarian mother was positively linked to bullying perpetration, which in turn was associated with increased alcohol use, and to a lesser degree, more alcohol-related problems. Mother authoritarianism was associated with alcohol-related problems through depressive symptoms. Three-path mediation analyses suggested a trend in which individuals with higher self-esteem were less likely to report alcohol-related problems through lower levels of bullying victimization and depression. Results suggested that bullying perpetration and victimization may respectively serve as externalizing and internalizing pathways through which parenting styles and self-esteem are linked to depression and alcohol-related outcomes. The present study identified multiple modifiable precursors of, and mediational pathways to, alcohol-related problems which could guide the development and implementation of prevention programs targeting problematic alcohol use.

    Full Text Available Abstract Background Minimotifs are short peptide sequences within one protein, which are recognized by other proteins or molecules. While there are now several minimotif databases, they are incomplete. There are reports of many minimotifs in the primary literature, which have yet to be annotated, while entirely novel minimotifs continue to be published on a weekly basis. Our recently proposed function and sequence syntax for minimotifs enables us to build a general tool that will facilitate structured annotation and management of minimotif data from the biomedical literature. Results We have built the MimoSA application for minimotif annotation. The application supports management of the Minimotif Miner database, literature tracking, and annotation of new minimotifs. MimoSA enables the visualization, organization, selection and editing functions of minimotifs and their attributes in the MnM database. For the literature components, Mimosa provides paper status tracking and scoring of papers for annotation through a freely available machine learning approach, which is based on word correlation. The paper scoring algorithm is also available as a separate program, TextMine. Form-driven annotation of minimotif attributes enables entry of new minimotifs into the MnM database. Several supporting features increase the efficiency of annotation. The layered architecture of MimoSA allows for extensibility by separating the functions of paper scoring, minimotif visualization, and database management. MimoSA is readily adaptable to other annotation efforts that manually curate literature into a MySQL database. Conclusions MimoSA is an extensible application that facilitates minimotif annotation and integrates with the Minimotif Miner database. We have built MimoSA as an application that integrates dynamic abstract scoring with a high performance relational model of minimotif syntax. MimoSA's TextMine, an efficient paper-scoring algorithm, can be used to

  17. Nuclear import and export signals of human cohesins SA1/STAG1 and SA2/STAG2 expressed in Saccharomyces cerevisiae.

    Full Text Available BACKGROUND: Human SA/STAG proteins, homologues of the yeast Irr1/Scc3 cohesin, are the least studied constituents of the sister chromatid cohesion complex crucial for proper chromosome segregation. The two SA paralogues, SA1 and SA2, show some specificity towards the chromosome region they stabilize, and SA2, but not SA1, has been shown to participate in transcriptional regulation as well. The molecular basis of this functional divergence is unknown. METHODOLOGY/PRINCIPAL FINDINGS: In silico analysis indicates numerous putative nuclear localization (NLS and export (NES signals in the SA proteins, suggesting the possibility of their nucleocytoplasmic shuttling. We studied the functionality of those putative signals by expressing fluorescently tagged SA1 and SA2 in the yeast Saccharomyces cerevisiae. Only the N-terminal NLS turned out to be functional in SA1. In contrast, the SA2 protein has at least two functional NLS and also two functional NES. Depending on the balance between these opposing signals, SA2 resides in the nucleus or is distributed throughout the cell. Validation of the above conclusions in HeLa cells confirmed that the same N-terminal NLS of SA1 is functional in those cells. In contrast, in SA2 the principal NLS functioning in HeLa cells is different from that identified in yeast and is localized to the C-terminus. CONCLUSIONS/SIGNIFICANCE: This is the first demonstration of the possibility of non-nuclear localization of an SA protein. The reported difference in the organization between the two SA homologues may also be relevant to their partially divergent functions. The mechanisms determining subcellular localization of cohesins are only partially conserved between yeast and human cells.

    Full Text Available The Internet is becoming increasingly interwoven in the daily lives of many individuals, organisations and nations. It has, to a large extent, had a positive effect on the way people communicate. It has also introduced new avenues for business; and it has offered nations an opportunity to govern online. Nevertheless, although cyberspace offers an endless list of services and opportunities, it is also accompanied by many risks, of which many Internet users are not aware. As such, various countries have developed and implemented cyber-security awareness and education measures to counter the perceived ignorance of the Internet users. However, there is currently a definite lack in South Africa (SA in this regard; as there are currently, little government-led and sponsored cyber-security awareness and education initiatives. The primary research objective of this paper, therefore, is to propose a cyber-security awareness and education framework for SA that would assist in creating a cyber-secure culture in SA among all of the users of the Internet. This framework will be developed on the basis of key factors extrapolated from a comparative analysis of relevant developed countries.
