Parasite stress promotes homicide and child maltreatment

Researchers using the parasite-stress theory of human values have discovered many cross-cultural behavioural patterns that inform a range of scholarly disciplines. Here, we apply the theory to major categories of interpersonal violence, and the empirical findings are supportive. We hypothesize that the collectivism evoked by high parasite stress is a cause of adult-on-adult interpersonal violence. Across the US states, parasite stress and collectivism each positively predicts rates of men's and women's slaying of a romantic partner, as well as the rate of male-honour homicide and of the motivationally similar felony-related homicide. Of these four types of homicide, wealth inequality has an independent effect only on rates of male-honour and felony-related homicide. Parasite stress and collectivism also positively predict cross-national homicide rates. Child maltreatment by caretakers is caused, in part, by divestment in offspring of low phenotypic quality, and high parasite stress produces more such offspring than low parasite stress. Rates of each of two categories of the child maltreatment--lethal and non-lethal--across the US states are predicted positively by parasite stress, with wealth inequality and collectivism having limited effects. Parasite stress may be the strongest predictor of interpersonal violence to date.     

Proximity to SNAP-authorized retailers and child maltreatment reports

The Supplemental Nutrition Assistance Program (SNAP) has been shown to have positive benefits for children. Families may face fewer barriers to accessing food they can purchase with their benefits if more stores in their neighborhoods accept SNAP benefits. We examine whether proximity to stores accepting SNAP benefits is related to child maltreatment (abuse and neglect) reports, particularly those potentially related to food insecurity. We combine geographically identified child maltreatment report data from the state of Connecticut from 2011 through 2015 with state SNAP-authorized retailer data. Using within-Census block group changes in the presence of a SNAP-authorized store, we find that in large, rural areas, one additional SNAP store is associated with a 4.4 percent decrease in the child maltreatment report rate (p < 0.05), and an 11.3 percent decrease in substantiated cases of maltreatment (p < 0.10), even net of changing zip code level factors and time-invariant neighborhood characteristics. The relationship between a neighborhood SNAP store and child maltreatment reports in these rural areas is largely driven by neglect, concentrated among young and school-aged children (ages 0–9), and primarily due to fewer reports by medical personnel. We find no effects of a neighborhood SNAP store on child maltreatment reports in smaller, more densely populated neighborhoods. Sensitivity checks affirm these results. Results indicate the benefits of access to SNAP retailers on the child welfare system and child well-being more broadly, especially in rural areas.     

Bradley's Benzedrine studies on children with behavioral disorders

In 1937, psychiatrist Charles Bradley administered Benzedrine sulfate, an amphetamine, to "problem" children at the Emma Pendleton Bradley Home in Providence, Rhode Island, in an attempt to alleviate headaches; however, Bradley noticed an unexpected effect upon the behavior of the children: improved school performance, social interactions, and emotional responses. Drawing on Bradley's published articles on his experiments, this paper explores the historical context of his experiments and the effect this background had on the emerging field of child psychiatry. Bradley's studies went largely ignored in the field of child psychiatry for nearly 25 years. However, they proved to be an important precursor to studies of amphetamines like Ritalin and their use in conditions such as attention deficit hyperactivity disorder. Bradley's Benzedrine trials were thus highly influential in shaping modern objective understandings of children with behavior disorders.     

The Social Life of Rights: ‘Gender Antagonism’, Modernity and Raet in Vanuatu

In the northern Vanuatu town of Luganville a small group of men have responded to social and legal changes engendered by women's rights activists by forming a male support group called ‘Violence Against Men’. Members of this ‘backlash’ movement argue that the insidious promotion of Western‐style ‘women's rights’ is leading to discrimination against men in divorce proceedings, child custody battles, and in domestic violence and rape cases. They directly oppose recent and ongoing legal changes aimed at protecting women from domestic violence, such as Domestic Violence Protection Court Orders, and the repeatedly tabled (but long‐delayed) ‘Family Protection Bill’. Such interventions, they argue, undermine Vanuatu's ‘natural’kastom and Christian patriarchal gender order and, in doing so, pose a serious threat to the socio‐economic productivity of the nation‐state. For other men, however, rather than opposing women's rights activism, such challenges have raised questions about how men might successfully negotiate their identities in ways that are sensitive to contemporary issues of gender equality without undermining existing paradigms. Thus, this paper addresses the value accorded to universalism and relativism in gender activism in Vanuatu, and especially in terms of the linked discourses of kastom, church and modernity. It therefore explores gender relations in terms of the contemporary entanglement of indigenous and exogenous epistemologies, and in doing so argues that the contextual analysis of ‘rights’ should consider the specific historical, political and socio‐cultural circumstances in which they are put to use.     

GENETIC VARIABILITY AND POTENTIAL SOURCES OF GRATELOUPIA DORYPHORA (HALYMENIACEAE,RHODOPHYTA), AN INVASIVE SPECIES IN RHODE ISLAND WATERS (USA)1

Grateloupia doryphora (Montagne) M.Howe is an invasive foliose alga that was reported for the first time in Rhode Island, USA in 1997. The population has since increased in size and expanded in range. In this study, the genetic variation and potential sources of the Rhode Island G. doryphora population were examined using three types of molecular markers: randomly amplified polymorphic DNA (RAPD), nuclear internal transcribed spacer (ITS) sequences, and mitochondrial cox2–cox3 intergenic spacer (COX) sequences. No variation was detected in ITS or COX sequences among Rhode Island G. doryphora individuals. RAPDs, however, did reveal genetic variation, although banding patterns were similar, with RAPD genetic distances between individuals ranging from 0.00 to 0.17. The low level of genetic diversity observed within the Rhode Island population may be due to a small founder population or a founder population derived from a genetically uniform source. To identify possible sources of the Rhode Island invasion, individuals from nine geographically diverse populations of foliose Grateloupia were compared. Phylogenetic trees inferred from RAPD distances and ITS and COX sequences had similar topologies; thus there was phylogenetic congruence among these independent loci. The Rhode Island G. doryphora specimens were genetically similar to specimens from G. doryphora populations located in Portsmouth, England; Tholen Island, The Netherlands; and Brittany and Hérault, France. Interestingly, the G. doryphora population in each of these locations is itself due to an introduction event within the past 40 years.     

Structural Pathways between Child Abuse,Poor Mental Health Outcomes and Male-Perpetrated Intimate Partner Violence (IPV)

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 against single and repeat episodes of IPV perpetration. There was a direct path between the history of child trauma and IPV perpetration and three other indirect paths showing the mediating effects of PTSD, other trauma and gender attitudes.

Conclusions

Child trauma is a risk factor for both poor mental health and male-perpetrated IPV among men in Gauteng. Male-perpetrated IPV in these settings should be explained through a combination of the Trauma, Feminist, and Intergenerational Transmission of Family Violence theories. Prevention interventions for male- perpetrated IPV in South Africa need to incorporate strategies and therapies to address poor mental health conditions.     

Political violence and child health: Results from Zimbabwe

This paper examines how the health of Zimbabwean children was affected by political and election-related violence and land reform in Zimbabwe during the period from 2000 to 2005. These events impacted Zimbabwean livelihoods and increased food insecurity in the country. Our study combines individual child data from the Demographic and Health Surveys that bracket these violent events with information on the location and date of violence from the Armed Conflict Location and Event dataset. To understand how the increase in violence impacted children’s health, the empirical analysis exploits temporal and spatial variation in child height across birth cohorts. Children born after the spike in violence in 2000 had lower height-for-age z-scores than children from earlier cohorts. The results are robust to a placebo test for parallel trends, alternative control groups, selective mortality, and migration. The paper adds to the literature on election-related violence, armed conflict, and land reform. Additionally, it provides guidance on differentiating between timing of violence during multiple political and electoral events, and estimating the impact on rural communities.     

AUTOGAMY AND INBREEDING DEPRESSION IN MOUNTAIN LAUREL,KALMIA LATIFOLIA (ERICACEAE)

We compared breeding systems, inbreeding depression, and pollination limitation between two populations of Kalmia latifolia in Virginia and Rhode Island. Plants were autogamous in Virginia but not Rhode Island. Although autogamy with selling is hypothesized to reduce levels of inbreeding depression, both populations showed similarly high inbreeding depression manifested as reduced fruit set. Autogamy may be uncorrelated with selling rate because autogamy is not obligate and because geitonogamy is likely. Autogamy in the Virginia population seems most likely to have evolved for reproductive assurance under competition for pollinator service. Fruit set was pollination limited in the Virginia population apparently because bumblebee pollinators were more attracted to a coflowering species, Vaccinium erythrocarpum.     

A systematic review of African studies on intimate partner violence against pregnant women: prevalence and risk factors

Background

Intimate partner violence (IPV) is very high in Africa. However, information obtained from the increasing number of African studies on IPV among pregnant women has not been scientifically analyzed. This paper presents a systematic review summing up the evidence from African studies on IPV prevalence and risk factors among pregnant women.

Methods

A key-word defined search of various electronic databases, specific journals and reference lists on IPV prevalence and risk factors during pregnancy resulted in 19 peer-reviewed journal articles which matched our inclusion criteria. Quantitative articles about pregnant women from Africa published in English between 2000 and 2010 were reviewed. At least two reviewers assessed each paper for quality and content. We conducted meta-analysis of prevalence data and reported odds ratios of risk factors.

Results

The prevalence of IPV during pregnancy ranges from 2% to 57% (n = 13 studies) with meta-analysis yielding an overall prevalence of 15.23% (95% CI: 14.38 to 16.08%). After adjustment for known confounders, five studies retained significant associations between HIV and IPV during pregnancy (OR1.48–3.10). Five studies demonstrated strong evidence that a history of violence is significantly associated with IPV in pregnancy and alcohol abuse by a partner also increases a woman''s chances of being abused during pregnancy (OR 2.89–11.60). Other risk factors include risky sexual behaviours, low socioeconomic status and young age.

Conclusion

The prevalence of IPV among pregnant women in Africa is one of the highest reported globally. The major risk factors included HIV infection, history of violence and alcohol and drug use. This evidence points to the importance of further research to both better understand IPV during pregnancy and feed into interventions in reproductive health services to prevent and minimize the impact of such violence.     

REPORT OF A NEW INVASIVE ALGA IN THE ATLANTIC UNITED STATES: “HETEROSIPHONIA” JAPONICA IN RHODE ISLAND1

Recent collections of tetrasporangiate “Heterosiphonia” japonica Yendo from Watch Hill to Point Judith, Rhode Island, represent the first report of this nonnative alga in the western Atlantic. Native to the Pacific Ocean, this species was unintentionally introduced into European waters by 1984 and has subsequently invaded the eastern Atlantic Ocean widely from France to Norway and south into the Mediterranean Sea. Thus far, all western Atlantic collections of this species are confined to the outer coast of Rhode Island, and at present are not found in Narragansett Bay or in Long Island Sound along the Connecticut coast. Molecular and morphological studies confirm the identity of this newly introduced invasive species.     

Schizophrenia and Violence: Systematic Review and Meta-Analysis

Background

Although expert opinion has asserted that there is an increased risk of violence in individuals with schizophrenia and other psychoses, there is substantial heterogeneity between studies reporting risk of violence, and uncertainty over the causes of this heterogeneity. We undertook a systematic review of studies that report on associations between violence and schizophrenia and other psychoses. In addition, we conducted a systematic review of investigations that reported on risk of homicide in individuals with schizophrenia and other psychoses.

Methods and Findings

Bibliographic databases and reference lists were searched from 1970 to February 2009 for studies that reported on risks of interpersonal violence and/or violent criminality in individuals with schizophrenia and other psychoses compared with general population samples. These data were meta-analysed and odds ratios (ORs) were pooled using random-effects models. Ten demographic and clinical variables were extracted from each study to test for any observed heterogeneity in the risk estimates. We identified 20 individual studies reporting data from 18,423 individuals with schizophrenia and other psychoses. In men, ORs for the comparison of violence in those with schizophrenia and other psychoses with those without mental disorders varied from 1 to 7 with substantial heterogeneity (I ² = 86%). In women, ORs ranged from 4 to 29 with substantial heterogeneity (I ² = 85%). The effect of comorbid substance abuse was marked with the random-effects ORs of 2.1 (95% confidence interval [CI] 1.7–2.7) without comorbidity, and an OR of 8.9 (95% CI 5.4–14.7) with comorbidity (p<0.001 on metaregression). Risk estimates of violence in individuals with substance abuse (but without psychosis) were similar to those in individuals with psychosis with substance abuse comorbidity, and higher than all studies with psychosis irrespective of comorbidity. Choice of outcome measure, whether the sample was diagnosed with schizophrenia or with nonschizophrenic psychoses, study location, or study period were not significantly associated with risk estimates on subgroup or metaregression analysis. Further research is necessary to establish whether longitudinal designs were associated with lower risk estimates. The risk for homicide was increased in individuals with psychosis (with and without comorbid substance abuse) compared with general population controls (random-effects OR = 19.5, 95% CI 14.7–25.8).

Conclusions

Schizophrenia and other psychoses are associated with violence and violent offending, particularly homicide. However, most of the excess risk appears to be mediated by substance abuse comorbidity. The risk in these patients with comorbidity is similar to that for substance abuse without psychosis. Public health strategies for violence reduction could consider focusing on the primary and secondary prevention of substance abuse. Please see later in the article for Editors'' Summary     

The impact of civil conflict on child health: Evidence from Colombia

Internal armed conflicts have become more common and more physically destructive since the mid-20th century, with devastating consequences for health and development in low- and middle-income countries. This paper investigates the causal impacts of the long-term internal conflict on child health in Colombia, following an identification strategy based on the temporal and geographic variation of conflict intensity. We estimate the effect of different levels of conflict intensity on height-for-age (HAZ), weight-for-age (WAZ), and weight-for-height z-scores among children under five years old, and explore the underlying potential mechanisms, through maternal health behavior and health care utilization. We find a harmful effect of exposure to conflict violence in utero and in early childhood for HAZ and WAZ, in the full sample and even more strongly in the rural sample, yet these estimates are smaller than those found for shorter term conflicts. The underlying pathways appear to operate around the time of the pregnancy and birth (in the form of maternal alcohol use, use of antenatal care and skilled birth attendance), rather than during the post-birth period (via breastfeeding or vaccination), and the impacts accumulate over the childhood. The most adverse impacts of conflict violence on child health and utilization of maternal healthcare were observed in municipalities which suffered from intermittent presence of armed groups.     

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.     

Recruitment patterns of scleractinian corals in an isolated sub-tropical reef system

The density of recruits of scleractinian corals on settlement plates at Lord Howe Island, a small isolated sub-tropical island 630 km off the Australian coastline, was within the range of values reported for comparable studies on the Great Barrier Reef. However, there was a difference in the relative abundance of taxonomic groups, with recruitment at Lord Howe Island during the summer of 1990/91 dominated by corals from the Family Pocilloporidae, Family Poritidae, and sub-genus Acropora (Isopora) (in order of abundance). By contrast, on the Great Barrier Reef, recruits are generally predominantly species from the Family Acroporidae (other than the Acropora (Isopora) group). Both the recruits and the established coral communities at Lord Howe Island are dominanted by corals which release brooded planulae, as opposed to the pattern of mass-spawning with external fertilisation more typical of Great Barrier Reef corals. I hypothesise that the release of brooded planulae would be advantageous in an isolated reef community because (a) brooded larvae can travel large distances and survive the journey to the isolated reef and/or (b) brooded larvae have a shorter period before they are competent to settle and are therefore more likely to be retained on the parental reef once a population has been established.     

Evidence on the impact of child labor on child health in Indonesia, 1993–2000

Despite an abundant literature on child labor in developing countries, few papers have attempted to investigate the consequences of child labor on health. This paper explores whether child labor affects child health using data from the Indonesian Socio-Economic Surveys during the 1990s. For our empirical analysis, we restrict our attention to children currently enrolled in school and we use several discrete indicators for health. Our results show that child labor is associated negatively with health. We obtain this result by introducing labor participation as an exogenous covariate in the different health equations. Similar results are found once the work decision is instrumented.     

Non-sedentarism,Violence and Politics of Assertive Egalitarianism among Calon Gypsies of Bahia,Brazil

The community life of Calon Romanies (Gypsies) in Bahia, northeast Brazil, is politically instituted through and by violence. Violence and fear of violence underlie Calon sociability and serve as a way to mark Calon as distinct from Jurons (non-Gypsies). Within communities, it undermines the tendency for personal power and efficacy to coalesce into rank, as well as the tendency for settlements to petrify into entities with fixed identities. Ultimately, the article argues, what makes violence practicable as a mode of fabricating social relations in the first place is Calon non-sedentarism, which posits one’s readiness to move as a mechanism through which belonging and relatedness are expressed, and which values flexibility in spatial arrangements rather than a fixed domicile.     

Impact of Adverse Childhood Experiences on Intimate Partner Violence Perpetration among Sri Lankan Men

In Sri Lanka, over one in three women experience intimate partner violence (IPV) victimization in their lifetime, making it a serious public health concern. Adverse childhood experiences (ACEs) such as child abuse and neglect, witnessing domestic violence, parental separation, and bullying are also widespread. Studies in Western settings have shown positive associations between ACEs and IPV perpetration in adulthood, but few have examined this relationship in a non-Western context. In the present study, we examined the association of ACEs with IPV perpetration among Sri Lankan men surveyed for the UN Multi-Country Study on Men and Violence in Asia and the Pacific. We found statistically significant positive associations between the number of ACE categories (ACE score) and emotional, financial, physical, and sexual IPV perpetration among Sri Lankan men. We analyzed the contributions of each ACE category and found that childhood abuse was strongly associated with perpetration of IPV in adulthood, with sexual abuse associated with the greatest increase in odds of perpetration (Adjusted odds ratio 2.36; 95% confidence interval: 1.69, 3.30). Witnessing abuse of one’s mother was associated with the greatest increase in the odds of perpetrating physical IPV (AOR 1.82; 95% CI: 1.29, 2.58), while lack of a male parental figure was not associated with physical IPV perpetration (AOR 0.76; 95% CI: 0.53, 1.09). These findings support a social learning theory of IPV perpetration, in which children who are exposed to violence learn to perpetrate IPV in adulthood. They also suggest that in Sri Lanka, being raised in a female-headed household does not increase the risk of IPV perpetration in adulthood compared to being raised in a household with a male parental figure. The relationship between being raised in a female-headed household (the number of which increased dramatically during Sri Lanka’s recent civil war) and perpetration of IPV warrants further study. Interventions that aim to decrease childhood abuse in Sri Lanka could both protect children now and reduce IPV in the future, decreasing violence on multiple fronts.     

MORPHOMETRY OF BATRACHOSPERMUM POPULATIONS INTERMEDIATE BETWEEN B. BORYANUM AND B. ECTOCARPUM (RHODOPHYTA)1

Batrachospermum plants collected as part of a comprehensive study of New England streams were found to be intermediate between B. boryanum Sirdt. find B. ectocarpum Sirdt. Sixty-four specimens from ten Rhode Island streams were examined for several characteristics in replicates of two to four hundred. The size ranges obtained were then compared with previous published data for B. boryanum and B. ectocarpum from Europe, Asia and North America. The Rhode Inland populations and individuals exhibited as much or even more variability as that reported for both species combined throughout the world. Therefore, it appears that there is no definite basis for separation of these taxa and it is proposed that they be merged under the name B. boryanum. This combined species ran be distinguished from other species of the section Batrachospermum by compressed mature lateral whorls, little secondary fascicle formation, curved distal branching, terminal hairs on a small proportion of branches, predominantly dioecious state, sessile trichogynes and carposporophytes in outer portions of lateral whorls.     

Focus: Sex and Gender Health: The Effects of Gender-based Violence on Women’s Unwanted Pregnancy and Abortion

The aim of this research is to understand how gender-based violence across the life-course affects the likelihood of abortion. Women outpatients (n = 309) revealed their exposure to four different forms of gender-based abuse: child sexual abuse (25.7 percent), teenage physical dating violence (40.8 percent), intimate partner violence (43.1 percent), and sexual assault outside an intimate relationship (22 percent). Logistic regressions revealed that no single form of gender-based abuse predicted abortion. The cumulative effect of multiple forms of abuse did increase the odds of having an abortion (OR = 1.39, CI = 1.13-1.69). Child sexual abuse predicted intimate partner violence (OR = 6.71, CI = 3.36-13.41). The cumulative effect of gender-based violence on women’s reproductive health warrants further research. Priority should be given to screening for multiple forms of victimization in reproductive healthcare settings.     

Breastfeeding and child disability: A comparison of siblings from the United States

Little is known about whether breastfeeding may prevent disabilities throughout childhood. We evaluate the effects of breastfeeding on child disability using data from the National Survey of Family Growth merged to the National Health Interview Survey for a large nationally representative sample of children aged 1–18 years from the U.S. including over 3000 siblings who are discordant on breastfeeding status/duration. We focus on a mother fixed effect model that compares siblings in order to account for family-level unobservable confounders and employ multiple specifications including a dynamic model that accounts for disability status of the prior child. Breastfeeding the child for a longer duration is associated with a lower risk of child disability, by about 0.2 percentage-points per month of breastfeeding. This effect is only observed on the intensive margin among breastfed children, as any breastfeeding has no effect on the extensive margin. We conclude that very short breastfeeding durations are unlikely to have an effect on reducing disability risk.
