Ethnic heterogamy and the risk of partner violence in Mexico

A common stereotype holds that in Mexico male violence toward women is common among indigenous peoples and reflects cultural norms that sanction a male's domination of his female partner. We employ a recent Mexican survey to examine the relative risk of violence against women as a function of the couple's ethnic homogamy. Among couples in which both partners are either non-indigenous or indigenous the female's risk of partner violence is similar. Among heterogamous couples non-indigenous females in relationships in which the male is indigenous are at elevated risk of violence, while indigenous women in relationships with non-indigenous males are at a lower risk of violence. The stresses associated with heterogamy appear to be more salient in determining a woman's risk of violence than ethnicity per se. The implications for future research and the need to deal with the issue of ethnic homogamy in culturally heterogeneous populations are discussed.     

Physical violence against intimate partners and related exposures to violence among South African men

Background

Despite high rates of intimate partner violence in South Africa, there have been no national studies of men''s perpetration of violence against female partners.

Methods

We analyzed data from the South Africa Stress and Health Study, a cross-sectional, nationally representative study, specifically examining data for men who had ever been married or had ever cohabited with a female partner. We calculated the prevalence of physical violence against intimate female partners and used logistic regression to examine associations with physical abuse during childhood and exposure to parental and community violence.

Results

A total of 834 male participants in the South Africa Stress and Health Study met the study criteria. Of these, 27.5% reported using physical violence against their current or most recent female partner during their current or most recent marriage or cohabiting relationship. Crude odds ratios (ORs) and 95% confidence intervals (CIs) indicated significant associations between perpetration of violence against an intimate partner and witnessing parental violence (OR 3.91, 95% CI 2.66–5.73) or experiencing physical abuse during childhood (OR 3.24, 95% CI 2.27–4.63), but not exposure to community violence (OR 1.29, 95% CI 0.88–1.88). The 2 significant associations persisted in adjusted analyses: OR 3.22 (95% CI 1.94–5.33) for witnessing parental violence and OR 1.73 (95% CI 1.07–2.79) for experiencing physical abuse during childhood.

Interpretation

We found a high prevalence of physical violence perpetrated by men against their intimate partners. Men who experienced physical abuse during childhood or were exposed to parental violence were at the greatest risk.Most research about men''s perpetration of violence against female intimate partners has concentrated on elucidating the factors that put women at risk for experiencing such violence and identifying the related service needs. Less work has been done to investigate the factors affecting men''s risk of perpetrating violence against women. Such work is needed to inform development of empirically based public health programs to reduce men''s use of such violence. Intimate partner violence is of pandemic proportions, with global estimates indicating that 15% to 75% of women have experienced such abuse.^1,2 Such violence may confer grave health consequences, including transmission of HIV/AIDS.³The overwhelming majority of research on violence against intimate partners perpetrated by men has been conducted in Western countries, with the focus on men at high risk for such activity (e.g., prisoners, people enrolled in intervention programs for batterers).^4,5 This work has highlighted the importance of exposure to violence early in life (e.g., witnessing parental violence, experiencing child abuse) in predicting perpetration of violence against a partner during adulthood.⁶ Recently, the potential relations between community violence and men''s perpetration of violence against intimate partners have also been examined.⁷Fewer studies have been done in developing nations, but several notable investigations have recently assessed men''s perpetration of violence against intimate partners in South Africa, specifically in Eastern Cape and Cape Town. Two of these studies have indicated high rates of violence against intimate partners: 31.8% in Eastern Cape⁸ and 42.3% in Cape Town.⁹ The extent to which these findings reflect national rates is unknown. Furthermore, work with both men and women in South Africa has demonstrated strong relations between violence (men''s perpetration and women''s victimization) and higher rates of sexually risky behaviours.^3,8 Associations between women''s experience as victims of intimate partner violence and HIV infection have also been documented.³ These data strongly suggest that men''s perpetration of violence against intimate partners is common in South Africa and that it may play an important role in this nation''s HIV epidemic,^3,8 which currently ranks highest in the world with respect to the number of people living with HIV.¹⁰In the study reported here, we sought to build upon prior work by using a national sample of South African men to examine the prevalence of physical violence perpetrated by men against their female intimate partners and potential violence-related risk factors (i.e., exposure to parental violence, experience of abuse in childhood and exposure to community violence).

Sex,money, and paternity: The evolutionary psychology of domestic violence

Three hundred sixty-five women, with children between six and 12 years of age, were interviewed and tested on various issues theoretically related to domestic violence. The sample was stratified into three subsamples of volunteer women recruited from: (1) a temporary shelter for battered women, (2) the local community and screened specifically for the reported presence of domestic violence, (3) the same community sources and screened only for the reported presence of children of the specified age group. Factor analytic structural equation models were constructed for the predictors of violence by the woman's main sexual partner toward the woman and towards the woman's child. Common factors were constructed for the four major dimensions of domestic violence— verbal, physical, escalated, and sexual—and for the three major predictors of domestic violence—sex, money, and paternity. The sex factor indexed the general quality of the sexual relationship dynamics, the money factor indexed the couple's socioeconomic relations, and the paternity factor indexed the genetic stakes held in the family by the woman's main sexual partner. These three factors jointly accounted for 60% of the variance in violence toward the woman. Violence towards the woman—the only significant direct effect—accounted for 26% of the variance in violence toward the child. These findings suggest that the principal perpetrators of domestic violence may be competitively disadvantaged males, pursuing coercive sexual and parental strategies without regard to the deleterious indirect effects upon their own genetic offspring.     

The Effects of Temperature on Political Violence: Global Evidence at the Subnational Level

A number of studies have demonstrated an empirical relationship between higher ambient temperatures and substate violence, which have been extrapolated to make predictions about the security implications of climate change. This literature rests on the untested assumption that the mechanism behind the temperature-conflict link is that disruption of agricultural production provokes local violence. Using a subnational-level dataset, this paper demonstrates that the relationship: (1) obtains globally, (2) exists at the substate level — provinces that experience positive temperature deviations see increased conflict; and (3) occurs even in regions without significant agricultural production. Diminished local farm output resulting from elevated temperatures is unlikely to account for the entire increase in substate violence. The findings encourage future research to identify additional mechanisms, including the possibility that a substantial portion of the variation is brought about by the well-documented direct effects of temperature on individuals'' propensity for violence or through macroeconomic mechanisms such as food price shocks.     

Partner Violence and Psychosocial Distress among Female Sex Workers in China

Background

Despite recognized vulnerability of female sex workers (FSW), most data on this population are focused on their HIV and STI prevalence; studies on their experience of partner violence and psychosocial distress are limited, especially FSW in China.

Methods and Findings

A cross-sectional survey was administered among 1,022 FSW recruited from 9 different types of commercial sex venues in Southwest China. Partner violence scales were adapted from WHO''s Women''s Health and Domestic Violence scale and psychosocial distress was measured by five indicators, including alcohol intoxication, drug use, suicidal behavior, depression, and loneliness. Random effects modeling was used to control for cluster effects. Findings: About 58% of FSW ever experienced violence from their stable partners, and 45% suffered it from their clients. Partner violence was strongly associated with each of the five measures of psychosocial distress, even after controlling for potential confounders.

Conclusion

This study is one of the first to examine the association between partner violence and psychosocial distress among FSW in China. The high prevalence of violence experience and distress in this population suggests urgency for intervention. The public health programs targeting FSW should go beyond the focus on HIV/STI prevention and care for the fundamental health and human rights of millions of FSW in China.     

"That Pregnancy Can Bring Noise into the Family": Exploring Intimate Partner Sexual Violence during Pregnancy in the Context of HIV in Zimbabwe

Background

Globally, studies report a high prevalence of intimate partner sexual violence (IPSV) and an association with HIV infection. Despite the criminalisation of IPSV and deliberate sexual HIV infection in Zimbabwe, IPSV remains common. This study explored women''s and health workers'' perspectives and experiences of sexuality and sexual violence in pregnancy, including in relation to HIV testing.

Methods

This qualitative study was part of a larger study of the dynamics of intimate partner violence and HIV in pregnancy in Zimbabwe. Key informant interviews were conducted with health workers and focus group discussions were held with 64 pregnant or nursing mothers attending antenatal and postnatal care clinics in low-income neighbourhoods of Harare, covering the major thematic areas of validated sexual violence research instruments. Thematic content analysis of audio-recorded and transcribed data was conducted.

Results

While women reported some positive experiences of sex in pregnancy, most participants commonly experienced coercive sexual practices. They reported that men failed to understand, or refused to accept, pregnancy and its associated emotional changes, and often forced painful and degrading sexual acts on them, usually while the men were under the influence of alcohol or illicit drugs. Men often refused or delayed HIV testing, and participants reported accounts of HIV-positive men not disclosing their status to their partners and deliberately infecting or attempting to infect them. Women''s passive acceptance of sexual violence was influenced by advice they received from other females to subordinate to their partners and to not deprive men of their conjugal sexual rights.

Conclusions

Cultural and societal factors, unequal gender norms and practices, women''s economic vulnerability, and men''s failure to understand pregnancy and emotional changes, influence men to perpetrate IPSV, leading to high risk of HIV infection.     

Obstetric Outcomes of Mothers Previously Exposed to Sexual Violence

Background

There is a scarcity of data on the association of sexual violence and women''s subsequent obstetric outcomes. Our aim was to investigate whether women exposed to sexual violence as teenagers (12–19 years of age) or adults present with different obstetric outcomes than women with no record of such violence.

Methods

We linked detailed prospectively collected information on women attending a Rape Trauma Service (RTS) to the Icelandic Medical Birth Registry (IBR). Women who attended the RTS in 1993–2010 and delivered (on average 5.8 years later) at least one singleton infant in Iceland through 2012 formed our exposed cohort (n = 1068). For each exposed woman''s delivery, nine deliveries by women with no RTS attendance were randomly selected from the IBR (n = 9126) matched on age, parity, and year and season of delivery. Information on smoking and Body mass index (BMI) was available for a sub-sample (n = 792 exposed and n = 1416 non-exposed women). Poisson regression models were used to estimate Relative Risks (RR) with 95% confidence intervals (CI).

Results

Compared with non-exposed women, exposed women presented with increased risks of maternal distress during labor and delivery (RR 1.68, 95% CI 1.01–2.79), prolonged first stage of labor (RR 1.40, 95% CI 1.03–1.88), antepartum bleeding (RR 1.95, 95% CI 1.22–3.07) and emergency instrumental delivery (RR 1.16, 95% CI 1.00–1.34). Slightly higher risks were seen for women assaulted as teenagers. Overall, we did not observe differences between the groups regarding the risk of elective cesarean section (RR 0.86, 95% CI 0.61–1.21), except for a reduced risk among those assaulted as teenagers (RR 0.56, 95% CI 0.34–0.93). Adjusting for maternal smoking and BMI in a sub-sample did not substantially affect point estimates.

Conclusion

Our prospective data suggest that women with a history of sexual assault, particularly as teenagers, are at increased risks of some adverse obstetric outcomes.     

‘Leemos!’: Perceptions of ethnic identity among settlers in north west river,Labrador*’

The influence of gender on patterns of ethnic violence in ex‐Yugoslavia has commanded considerable international attention. This article acknowledges the groundbreaking role of feminist scholarship in bringing the gender variable to the forefront in analyses of political and interpersonal violence. However, feminist applications of gender frameworks are to some extent constrained by feminism's normative commitments. The present article argues for a more balanced and inclusive understanding of the role gender plays in conditioning the actions and experiences of men and women alike, in the Balkans war and other conflicts. Towards this end, a detailed evaluation of gender‐specific and gender‐selective violence in ex‐Yugoslavia is presented, with particular attention to the group that appears to constitute the majority of victims ‐ males between the ages of eighteen and sixty‐five. The article concludes by stressing the importance of the gender variable in analysing ethnic and political violence, and suggests that a more nuanced approach to this variable's operations would shed important light on ethnic violence in ex‐Yugoslavia and worldwide.     

De-indigenized but not defeated: race and resistance in Colombia's Peace Community and Campesino University

Despite the institution of multicultural policies and pluriethnic governments across Latin America, racist violence against Indigenous and Afro-descendant groups persists. Yet the racial facets of violence against non-ethnic campesinos remain unexplored. Integrating scholarship on race as a global structure and Latin American racial formations, I offer an account of racialization in Colombia. This article analyzes the racial dynamics of resistance to extractivism in Colombia's Campesino University, uniting Indigenous and campesino groups like the San José de Apartadó Peace Community. While the dominant race lexicon separates “campesinos” like San José's peasants from “Indigenous” and “Black” groups, I argue that the identifier campesino mestizo hides how San José's farmers were “de-indigenized” yet remain racialized as the less-than-human “Indigenous savage”. If racialization works to dominate but also divide the subaltern, then Campesino University participants’ cross-ethnic solidarity network against what they affirm is a shared experience of racist violence both unveils and counters racism.     

A Meta-Analysis of the Val158Met COMT Polymorphism and Violent Behavior in Schizophrenia

We conducted a meta-analysis of studies examining the association between the Val158Met COMT polymorphism and violence against others in schizophrenia. A systematic search current to November 1, 2011 was conducted using MEDLINE, EMBASE, CINAHL, PsycINFO, ProQuest, and the National Criminal Justice Reference Service and identified 15 studies comprising 2,370 individuals with schizophrenia for inclusion. Bivariate analyses of study sensitivities and specificities were conducted. This methodology allowed for the calculation of pooled diagnostic odds ratios (DOR). Evidence of a significant association between the presence of a Met allele and violence was found such that men''s violence risk increased by approximately 50% for those with at least one Met allele compared with homozygous Val individuals (DOR = 1.45; 95% CI = 1.05–2.00; z = 2.37, p = 0.02). No significant association between the presence of a Met allele and violence was found for women or when outcome was restricted to homicide. We conclude that male schizophrenia patients who carry the low activity Met allele in the COMT gene are at a modestly elevated risk of violence. This finding has potential implications for the pharmacogenetics of violent behavior in schizophrenia.     

Violence in the emergency department: a survey of health care workers

BACKGROUND: Violence in the workplace is an ill-defined and underreported concern for health care workers. The objectives of this study were to examine perceived levels of violence in the emergency department, to obtain health care workers'' definitions of violence, to determine the effect of violence on health care workers and to determine coping mechanisms and potential preventive strategies. METHODS: A retrospective written survey of all 163 emergency department employees working in 1996 at an urban inner-city tertiary care centre in Vancouver. The survey elicited demographic information, personal definition of violence, severity of violence, degree of stress as a result of violence and estimate of the number of encounters with violence in the workplace in 1996. The authors examined the effects of violence on job performance and job satisfaction, and reviewed coping and potential preventive strategies. RESULTS: Of the 163 staff, 106 (65%) completed the survey. A total of 68% (70/103) reported an increased frequency of violence over time, and 60% (64/106) reported an increased severity. Most of the respondents felt that violence included witnessing verbal abuse (76%) and witnessing physical threats or assaults (86%). Sixty respondents (57%) were physically assaulted in 1996. Overall, 51 respondents (48%) reported impaired job performance for the rest of the shift or the rest of the week after an incident of violence. Seventy-seven respondents (73%) were afraid of patients as a result of violence, almost half (49%) hid their identities from patients, and 78 (74%) had reduced job satisfaction. Over one-fourth of the respondents (27/101) took days off because of violence. Of the 18 respondents no longer working in the emergency department, 12 (67%) reported that they had left the job at least partly owing to violence. Twenty-four-hour security and a workshop on violence prevention strategies were felt to be the most useful potential interventions. Physical exercise, sleep and the company of family and friends were the most frequent coping strategies. INTERPRETATION: Violence in the emergency department is frequent and has a substantial effect on staff well-being and job satisfaction.     

The ‘SONY NIGHTCLUB’: Rural Brothels,Gender Violence,and Development in Coastal Ecuador

ABSTRACT

In the Ecuadorian public imaginary, Manabí province is constructed as a lawless frontier. Manaba men are characterized for their aggressive masculinity, robust and primitive sexuality, and their proclivity towards resolving conflict with violence. This paper examines community debates about brothels and healthy sexuality in a rural coastal region where the state is expanding its reach into domestic life via the regulation of sexual intimacies and family violence. Local debates about healthy sexuality embody the historically contested and currently changing nature of state–community relationships in this previously marginalized region. While certain community factions invoke modernizing discourses of women's rights in their struggle to shut down brothels and mitigate family violence, others argue for unregulated sexuality as a way to diminish violence. Drawing from over 10 years of ethnographic research on gender, violence, and human rights in Ecuador, this paper reveals the co-construction of rural intimacies and the boundaries of state intervention.     

A thin slice of violence: distinguishing violent from nonviolent sex offenders at a glance

A growing body of literature in evolutionary psychology suggests that person perception processes are adaptively tuned. The current investigation tested the hypothesis that people would be able to detect a propensity for violence in other people, based only on a brief glance at their face. Participants estimated the propensity for violence in 87 registered sex offenders after seeing photos of them for 2 s each. Estimated likelihood of violence was significantly related to actual violent history, suggesting that violent tendencies can be accurately inferred from a brief look at a person's face. Cues indicative of high masculinity and high levels of male sex hormones (heavy brow, general facial masculinity, high physical strength, younger age) were related to accurate judgments. Other cues such as facial emotion and good grooming were not associated with an actual history of violence, but nevertheless correlated with raters' judgments. Although there were no sex differences in accuracy, on average women thought targets were more violent than men did. Findings speak to the accuracy and efficiency with which people can detect potential threats to physical well-being.     

Interracial status competition and southern lynching, 1882–1930

This article provides theoretical grounds and empirical evidence that different types of lynching in the post-Reconstruction South were driven by social processes at different levels of analysis. County-level analyses based upon new detailed data on lynchings in Georgia and Louisiana from 1882 to 1930 reveal that ‘private' lynchings, perpetrated by small groups outside the public purview without manifest ritual, were related to whites’ interracial status and social identity concerns on the interpersonal level, whereas ‘public' lynchings, involving larger mobs and ritualized violence, appear unaffected by such dynamics. These results validate relational and interactionist perspectives on violence, lend support to calls for disaggregation in the study of racial, ethnic, and nationalist violence, and shed light on the intertwining of racial identity formation with the generation of racial inequalities. They also carry implications for the study of contemporary ethno-racial hate crime.     

Time Series Analysis of Sexual Assault Case Characteristics and the 2007–2008 Period of Post-Election Violence in Kenya

Background

Following the declaration that President Mwai Kibaki was the winner of the Kenyan presidential election held on December 27, 2007, a period of post-election violence (PEV) took place. In this study, we aimed to identify whether the period of PEV in Kenya was associated with systematic changes in sexual assault case characteristics.

Methods and Findings

Medical records of 1,615 patients diagnosed with sexual assault between 2007 and 2011 at healthcare facilities in Eldoret (n = 569), Naivasha (n = 534), and Nakuru (n = 512) were retrospectively reviewed to examine characteristics of sexual assault cases over time. Time series and linear regression were used to examine temporal variation in case characteristics relative to the period of post-election violence in Kenya. Key informant interviews with healthcare workers at the sites were employed to triangulate findings. The time series of sexual assault case characteristics at these facilities were examined, with a specific focus on the December 2007–February 2008 period of post-election violence. Prais-Winsten estimates indicated that the three-month period of post-election violence was associated with a 22 percentage-point increase in cases where survivors did not know the perpetrator, a 20 percentage-point increase in cases with more than one perpetrator, and a 4 percentage-point increase in cases that had evidence of abdominal injury. The post-election violence period was also associated with an 18 percentage-point increase in survivors waiting >1 month to report to a healthcare facility. Sensitivity analyses confirmed that these characteristics were specific to the post-election violence time period.

Conclusion

These results demonstrate systematic patterns in sexual assault characteristics during the PEV period in Kenya.     

Crucible of fire: the Boer War and the birth of the Canadian Army Medical Corps.

Although Canada''s military physicians didn''t come to prominence until WW I and WW II, the Canadian Army Medical Corps (CAMC), the forerunner of the Royal Canadian Army Medical Corps and the current Canadian Forces Medical Service, actually had its origins in the Boer War. During that turn-of-the-century conflict, field hospitals accompanied Canadian troops to South Africa. Ian McCulloch discusses that early type of medical service and the steps that led to the creation of the CAMC.     

CMA's CEO re-elected chair of World Medical Association's ethics committee

The CMA secretary general, Dr. Léo-Paul Landry, has been re-elected chair of the World Medical Association''s (WMA) Medical Ethics Committee. During an April meeting, the committee approved documents dealing with reductions in the number of embryos and the care of patients with mental illness. The author says a steady increase in WMA membership is a sign of physicians'' belief in the importance of the association''s representational function.
