Purpose

To examine whether interpersonal violence perpetration and violence toward objects are associated with body mass index (BMI), body weight perception (BWP), and repeated weight-loss dieting in female adolescents.

Methods

A cross-sectional survey using a self-report questionnaire was performed evaluating interpersonal violence perpetration, violence toward objects, the number of diets, BMI, BWP, the 12-item General Health Questionnaire (GHQ-12), victimization, substance use, and other psychosocial variables among 9,112 Japanese females aged between 12–18 years. Logistic regression analysis was conducted to analyze the contribution of BMI, BWP, and weight-control behavior to the incidence of violent behavior, while controlling for potential confounding factors.

Results

The number of diets was associated with both interpersonal violence perpetration (OR = 1.18, 95% CI 1.08–1.29, p<0.001) and violence toward objects (OR = 1.34, 95% CI 1.24–1.45, p<0.001), after adjusting for age, BMI, BWP, the GHQ-12 total score, victimization, and substance use. In terms of BMI and BWP, the “overweight” BWP was associated with violence toward objects (OR = 1.29, 95% CI 1.07–1.54, p<0.05). On the other hand, the “Underweight” and “Slightly underweight” BMI were related to violence toward objects [(OR = 1.28, 95% CI 1.01–1.62, p<0.05) and (OR = 1.27, 95% CI 1.07–1.51, p<0.05), respectively]. The “Underweight” BWP was related to interpersonal violence perpetration (OR = 2.30, 95% CI 1.38–3.84, p<0.05).

Conclusions

The cumulative number of diets is associated with violent behavior in female adolescents. In addition, underweight BMI and extreme BWP are associated with violent behavior.  相似文献

Objectives To establish changes over time in the frequency of homicides committed by strangers, and to describe the personal and clinical characteristics of perpetrators of stranger homicides.Design Longitudinal study and national clinical survey.Participants People convicted of homicide in England and Wales between 1996 and 1999 and whether the victim was known to the perpetrator.Setting England and Wales.Main outcome measure Characteristics of perpetrators of homicides according to whether victims were strangers or not.Results Stranger homicides increased between 1967 and 1997, both in number and as a proportion of all homicides. No increase was found, however, in the number of perpetrators placed under a hospital order after homicide, whether all homicides or stranger homicides only. 358 of 1594 (22%) homicides were stranger homicides. In these cases the perpetrator was more likely to be male and young. The method of killing was more likely to be by hitting, kicking, or pushing (36% (130 of 358) for victims who were strangers to the perpetrator compared with 14% (145 of 1074) for victims who were known). Perpetrators were less likely to have a history of mental disorder (34%, n = 80 ν 50%, n = 142), a history of contact with mental health services (16%, 37 of 234 ν 24%, 200 of 824), and psychiatric symptoms at the time of the offence (6%, n = 14 ν 18%, n = 143). They were more likely to have a history of drug misuse (47%, n = 93 ν 37%, n = 272); alcohol (56%, n = 94 ν 41%, n = 285) or drugs (24% n = 44 ν 12%, n = 86) were more likely to have contributed to the offence.Conclusions Stranger homicides have increased, but the increase is not the result of homicides by mentally ill people and therefore the “care in the community” policy. Stranger homicides are more likely to be related to alcohol or drug misuse by young men.  相似文献

Empathy covers a wide range of phenomena varying according to the degree of cognitive complexity involved; ranging from emotional contagion, defined as the sharing of others’ emotional states, to sympathetic concern requiring animals to have an appraisal of the others’ situation and showing concern-like behaviors. While most studies have investigated how animals reacted in response to conspecifics’ distress, dogs so far have mainly been targeted to examine cross-species empathic responses. To investigate whether dogs would respond with empathy-like behavior also to conspecifics, we adopted a playback method using conspecifics’ vocalizations (whines) recorded during a distressful event as well as control sounds. Our subjects were first exposed to a playback phase where they were subjected either to a control sound, a familiar whine (from their familiar partner) or a stranger whine stimulus (from a stranger dog), and then a reunion phase where the familiar partner entered the room. When exposed to whines, dogs showed a higher behavioral alertness and exhibited more stress-related behaviors compared to when exposed to acoustically similar control sounds. Moreover, they demonstrated more comfort-offering behaviors toward their familiar partners following whine playbacks than after control stimuli. Furthermore, when looking at the first session, this comfort offering was biased towards the familiar partner when subjects were previously exposed to the familiar compared to the stranger whines. Finally, familiar whine stimuli tended to maintain higher cortisol levels while stranger whines did not. To our knowledge, these results are the first to suggest that dogs can experience and demonstrate “empathic-like” responses to conspecifics’ distress-calls.  相似文献

We respond more quickly to our own face than to other faces, but there is debate over whether this is connected to attention-grabbing properties of the self-face. In two experiments, we investigate whether the self-face selectively captures attention, and the attentional conditions under which this might occur. In both experiments, we examined whether different types of face (self, friend, stranger) provide differential levels of distraction when processing self, friend and stranger names. In Experiment 1, an image of a distractor face appeared centrally – inside the focus of attention – behind a target name, with the faces either upright or inverted. In Experiment 2, distractor faces appeared peripherally – outside the focus of attention – in the left or right visual field, or bilaterally. In both experiments, self-name recognition was faster than other name recognition, suggesting a self-referential processing advantage. The presence of the self-face did not cause more distraction in the naming task compared to other types of face, either when presented inside (Experiment 1) or outside (Experiment 2) the focus of attention. Distractor faces had different effects across the two experiments: when presented inside the focus of attention (Experiment 1), self and friend images facilitated self and friend naming, respectively. This was not true for stranger stimuli, suggesting that faces must be robustly represented to facilitate name recognition. When presented outside the focus of attention (Experiment 2), no facilitation occurred. Instead, we report an interesting distraction effect caused by friend faces when processing strangers’ names. We interpret this as a “social importance” effect, whereby we may be tuned to pick out and pay attention to familiar friend faces in a crowd. We conclude that any speed of processing advantages observed in the self-face processing literature are not driven by automatic attention capture.  相似文献

Decisions to help those in need are essential for human development and survival. Previous studies have demonstrated the “identified effect”, in which one identifiable individual typically invokes stronger feelings of compassion and receives greater aid than statistical victim. However, this preference might be influenced by cultural differences. In the current study, Chinese respondents’ ratings of distress and sympathy and their willingness to contribute are greater for a group of sick children than an individual. In the U.S., greater willingness to help and sympathy are elicited by an identified victim in comparison with an unidentified one. The different results may demonstrate the importance of cultural differences when trying to understand people’s prosocial behavior.  相似文献

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.  相似文献

Paul Farmer, physician, anthropologist, and author, spoke at the 2009 Society for Medical Anthropology Conference at Yale University in September.Medical anthropology is a very young field, only approximately 50 years old. The underpinnings of medical anthropology have been around for some time, but as a discipline, the burden to ensure that it continues to flourish and grow belongs to future generations of students and scholars. However, future generations of medical anthropologists cannot carry the field forward unless they examine the teachings of previous teachers and scholars. By narrating his own story, just as he so frequently narrates the intricacies of Haiti [1], Paul Farmer, physician, anthropologist, and author of Pathologies of Power: Health, Human Rights, and the New War on the Poor [2], displayed a parallel between the stories of his own past with that of medical anthropology.At the 2009 Society for Medical Anthropology Conference at Yale University in September, Farmer began his aptly titled presentation, Photo Album, with a discussion of his introduction to medical anthropology while an undergraduate at Duke. He stumbled upon medical anthropology quite by chance as an ambitious pre-med who was interested in taking every course that had the word “medical” in its title. He credited many people, including Patricia Pessar, Arthur Kleinman, and Linda Garro with aiding the development of his ideas and perception of the world and teaching him to use medical anthropology not only in passive observation, but in the active practice of medicine. You “don’t have to be a faculty member to teach,” stressed Farmer. Some of the most important lessons to learn come from the poor, to whom few listen.Farmer believes that listening can form the work we do. He honed his listening skills, which are used in anthropology in an ethnographic context, after his first night in an emergency room, when he saw that many minor cases were brought in solely because individuals had no other outlet for treatment. Being a good listener allowed Farmer to understand the full impact of a 1981 slavery case involving migrant workers in Florida. It was this skill of listening that enabled Farmer to understand and tell Haiti’s story, as well as understand the intricate web that exists between privilege and privation. Just as the line between medical anthropology and primary care is often blurred, the “bracing connection between privilege and privation” becomes even more apparent the longer one spends studying both extremes.This is a vantage point Farmer was particularly susceptible to, given his trips from Haiti to Harvard and back again. Listening to his patients in Haiti and the United States would allow Farmer to draw parallels of inequality and injustice that exist for the impoverished in both places. The only difference between the United States and Haiti is that eventually many impoverished individuals in the United States will wind up in somewhat adequate medical facilities. In the story of global economics, Farmer said, “Good things get stuck in customs and bad things get traded freely.” A practicing physician may easily note that inequalities between the rich and poor are not unique to the United States or to Haiti, but what, Farmer asks, can anthropologists say about this division?The cursory glance through Farmer’s photo album ended with a picture of friends whom he fondly termed “the structural violence mafia” and anthropological ideas regarding unequal access to health care. While at first, the portion of anthropology that dissects the structures of violence seems isolated from medical anthropology, those structures of violence institute the vast inequalities that cause medicine to seem inaccessible. Farmer also stressed that “how we think about social theory influences global health.” Work in Haiti taught Farmer firsthand about the phenomenon of blaming the victim [3]. To understand this entrenched system of structural violence fully, an intensive bio-social analysis must be undertaken. Structural violence results in a system in which the victims are blamed, empowering those who suppress the victim while inhibiting the victim’s access to health care. Pointing fingers at the vulnerable is illustrated by the fact that Haiti is often blamed for the introduction of AIDS into North America [4,5]. Farmer stressed not only the inherent trauma of structural violence, but Carolyn Nordstrom’s ideas on violence having a distinct tomorrow [6]. The perpetual cycle of structural violence enables this concept of violence having a clear future with the inherent cultural systems that allow for violence remaining stagnant while the individuals entrapped within the system change.Beyond this concept of structural violence is that of structural healing [3]. Though structural healing is a new phenomenon being examined by anthropologists, it provides a balance to structural violence with the idea being that there are certain societal standards that are either in place or can be introduced that allow for an alleviation of the suffering caused by structural violence. While Farmer’s discussion of the path that led him to his current position was inspirational in itself, the sharing of his story is of even more importance because he has been a teacher to so many. His story reinforces the idea that even though structural violence has a definite past and future, so do medical anthropology and the idea of structural healing. Thankfully, medical anthropology may be used as a relatively new force to combat structural violence. Farmer’s speech may have been unexpected in its autobiographical content, but perhaps the main point is that the intersection between medicine and anthropology can be seen not as a single point but a line that runs the full length of each of these disciplines. We all have a distinct responsibility to not only hear but to listen and learn, not to just passively observe, but actively understand. It is with this listening and acting, that future medical anthropologists can bridge the gap between social sciences and practical medicine.  相似文献

Despite considerable attention to chimpanzee intergroup violence, the number of observed cases remains small. We report 4 cases of intergroup violence that occurred in Gombe National Park, Tanzania, between 1993 and 2002. We observed (3 cases) or inferred (1 case) males from the Kasekela community to attack members of their 2 neighboring communities: Mitumba and Kalande. In 1993, Kasekela males killed and ate a female infant from Mitumba. In 1998, Kasekela males captured 2 infants (sex unknown) from Kalande, one of which escaped and the other was killed and eaten. Also in 1998, Kasekela males attacked an adolescent male from Kalande. The victim was alive but severely injured by the end of the attack. The intensity and duration of the attack are comparable to other attacks that resulted in fatal injuries. In 2002, observers found the body of an adolescent male from Mitumba following an incursion by Kasekela males into the area. The injuries inflicted on the Mitumba male together with circumstantial evidence suggest that Kasekela males killed him. The attacks support the view that intergroup violence is a persistent feature of chimpanzee societies and that the primary benefit attackers gain from them is reduced competition for resources.  相似文献

Background

The recent World Report on Disability highlighted violence as a leading cause of morbidity among disabled people. However, we know little about the extent to which people with disability experience different violence types, and associated health/economic costs. The recent introduction of disability measures into the England&Wales victimization survey provided an opportunity to address this gap.

Methods and Findings

Analysis of the 2009/10 British Crime Survey (BCS), a nationally representative cross-sectional survey of 44,398 adults living in residential households in England&Wales. Using multivariate logistic regression, we estimated the relative odds of being a victim of past-year violence (physical/sexual domestic or non-domestic violence) in people with disability compared to those without, after adjusting for socio-demographics, behavioural and area confounders. 1256/44398(2.4%) participants had one or more disabilities including mental illness (‘mental illness’) and 7781(13.9%) had one or more disabilities excluding mental illness (‘non-mental disability’). Compared with the non-disabled, those with mental illness had adjusted relative odds (aOR) of 3.0(95% confidence interval (CI) 2.3–3.8) and those with non-mental disability had aOR of 1.8(95% CI: 1.5–2.2) of being a victim of past-year violence (with similar relative odds for domestic and non-domestic violence). Disabled victims were more likely to suffer mental ill health as a result of violence than non-disabled victims. The proportion of violence that could be attributed to the independent effect of disability in the general population was 7.5%(CI 5.7–9.3%), at an estimated cost of £1.51 billion. The main study limitation is the exclusion of institutionalised people with disability.

Conclusions

People with disability are at increased risk of being victims of domestic and non-domestic violence, and of suffering mental ill health when victimized. The related public health and economic burden calls for an urgent assessment of the causes of this violence, and national policies on violence prevention in this vulnerable group.  相似文献

Previous research has shown that ideas which violate our expectations, such as schema-inconsistent concepts, enjoy privileged status in terms of memorability. In our study, memory for concepts that violate cultural (cultural schema-level) expectations (e.g., “illiterate teacher”, “wooden bottle”, or “thorny grass”) versus domain-level (ontological) expectations (e.g., “speaking cat”, “jumping maple”, or “melting teacher”) was examined. Concepts that violate cultural expectations, or counter-schematic, were remembered to a greater extent compared with concepts that violate ontological expectations and with intuitive concepts (e.g., “galloping pony”, “drying orchid”, or “convertible car”), in both immediate recall, and delayed recognition tests. Importantly, concepts related to agents showed a memory advantage over concepts not pertaining to agents, but this was true only for expectation-violating concepts. Our results imply that intuitive, everyday concepts are equally attractive and memorable regardless of the presence or absence of agents. However, concepts that violate our expectations (cultural-schema or domain-level) are more memorable when pertaining to agents (humans and animals) than to non-agents (plants or objects/artifacts). We conclude that due to their evolutionary salience, cultural ideas which combine expectancy violations and the involvement of an agent are especially memorable and thus have an enhanced probability of being successfully propagated.  相似文献

During 12 years of observation, we have observed three confirmed and two inferred lethal coalitionary attacks on adult male white-faced capuchins (Cebus capucinus) by members of two habituated social groups at Lomas Barbudal Biological Reserve, Costa Rica. In one case, an alpha male was badly wounded and evicted from his group, and when later found by his former groupmates he was attacked by several of them and died less than 24 h later. In two other cases, lone extra-group males were mobbed by adult and immature males of a bisexual group. One victim's abdomen was torn open and he died less than 24 h later. A second victim was quite badly bitten but may have escaped. The fourth and fifth cases resulted from intergroup encounters. One victim lost the use of both arms but may have survived, whereas the other died of unknown causes within an hour of the attack. The observed death rate from coalitionary aggression at our site is approximately the same as that reported for eastern chimpanzees. Because at least three of the five observed incidents involved large coalitions attacking lone victims, they support the general hypothesis that imbalances of power contribute to intraspecific killing in primates. However, the occurrence of lethal coalitional attacks in a species lacking fission–fusion social organization poses a challenge to the more specific version of the imbalance-of-power hypothesis proposed by Manson and Wrangham in 1991 to explain chimpanzee and human intergroup aggression.  相似文献

The mechanism of injury to the back should be obtained with the utmost accuracy and set down in the history as a separate paragraph under that heading. This is usually best obtained by questioning and requestioning the patient during the course of the examination. A history of any previous back affections should also be obtained at the first visit.The detailed examination of the back is not complete without a general physical examination.X-ray studies should be done immediately in all cases in which the injury has been caused by direct violence or forceful indirect violence (as in “jackknife” injury).Terms such as “disc disease,” “ruptured intervertebral disc” and various others that convey a similar meaning should not be used as the initial diagnosis and should be withheld until such a diagnosis is definitely established.The plan of treatment may include a period in hospital or of rest at home, or it may be carried out with the patient ambulatory. Corsets and braces should be prescribed only when they are to serve a definite function and the same can be said of physiotherapy.  相似文献

We aim to provide one explanation for why the link between contact and prejudice is consistently less strong for minority group members than it is for majority group members. Specifically, we propose a “wallpaper effect” such that contact works to increase minority group members'' positivity towards majority groups when they live in areas densely populated with other minority group members. Conversely, we suggest that when minority group members live in neighborhoods patterned with majority group faces (as is so often the case), contact will be less transformative. We test this assumption using a large sample of both New Zealander minority (Māori; N = 925) and majority (European; N = 3805) group members. In line with predictions, Māori who lived in minority dense neighborhoods showed the traditional association between contact and increased warmth towards New Zealander Europeans. This relationship, however, was weak or non-existent when they lived in primarily European neighborhoods. Contact effects in majority group members were unaffected by neighborhood composition. The interaction held when controlling for, and was not explained by: gender, income, experiences of harm, cognitions of race-based rejection, or realistic threat. We provide the first evidence to suggest that when it comes to minority group members'' intergroup attitudes, contact with majority group members may be a relatively ineffective predictor unless the “wallpaper” of their lives is minority-dense.  相似文献

Background

Little is known about the extent to which being a victim of domestic violence is associated with different mental disorders in men and women. We aimed to estimate the prevalence and odds of being a victim of domestic violence by diagnostic category and sex.

Methods

Study design: Systematic review and meta-analysis. Data Sources: Eighteen biomedical and social sciences databases (including MEDLINE, EMBASE, PsycINFO); journal hand searches; scrutiny of references and citation tracking of included articles; expert recommendations, and an update of a systematic review on victimisation and mental disorder. Inclusion criteria: observational and intervention studies reporting prevalence or odds of being a victim of domestic violence in men and women (aged ≥16 years), using validated diagnostic measures of mental disorder. Procedure: Data were extracted and study quality independently appraised by two reviewers. Analysis: Random effects meta-analyses were used to pool estimates of prevalence and odds.

Results

Forty-one studies were included. There is a higher risk of experiencing adult lifetime partner violence among women with depressive disorders (OR 2.77 (95% CI 1.96–3.92), anxiety disorders (OR 4.08 (95% CI 2.39–6.97), and PTSD (OR 7.34 95% CI 4.50–11.98), compared to women without mental disorders. Insufficient data were available to calculate pooled odds for other mental disorders, family violence (i.e. violence perpetrated by a non-partner), or violence experienced by men. Individual studies reported increased odds for women and men for all diagnostic categories, including psychoses, with a higher prevalence reported for women. Few longitudinal studies were found so the direction of causality could not be investigated.

Conclusions

There is a high prevalence and increased likelihood of being a victim of domestic violence in men and women across all diagnostic categories, compared to people without disorders. Longitudinal studies are needed to identify pathways to being a victim of domestic violence to optimise healthcare responses.  相似文献

Background

Death is the most extreme consequence of intimate partner violence. Female homicide studies with data on the perpetrator–victim relationship can provide insights. We compare the results of two South African national studies of female homicide with similar sampling done 10 y apart.

Methods and Findings

We conducted a retrospective national survey using a weighted cluster design of a proportionate random sample of 38 mortuaries to identify homicides committed in 2009. We abstracted victim data from mortuary and autopsy reports, and perpetrator data from police interviews. We compared homicides of women 14 y and older in 2009 with previously published data collected with the same methodology for homicides committed in 1999.The study found that the rate of female homicide per 100,000 female population in 2009 was 12.9 (95% confidence interval [CI]: 9.3, 16.5), compared to 24.7 (95% CI: 17.7, 31.6) in 1999. The incidence rate ratio of 0.54 (95% CI: 0.20, 0.84) reflects a significantly lower rate in 2009. The rate of intimate partner femicide was 5.6/100,000 in 2009 versus 8.8/100,000 in 1999, with an incidence rate ratio of 0.63 (95% CI: 0.24, 1.02), indicating no difference between rates. Logistic regression analysis of homicide characteristics showed that the odds ratio of suspected rape among non-intimate femicides in 2009 compared to 1999 was 2.61 (95% CI: 1.23, 4.08) and among intimate partner femicides it was 0.84 (95% CI: 0.50, 1.42). The OR of homicide by gunshot was 0.54 (95% CI: 0.30, 0.99) in 2009 versus 1999. There was a significant drop in convictions of perpetrators of non-intimate femicide in 2009 versus 1999 (OR = 0.32 [95% CI: 0.19, 0.53]). Limitations of the study include the relatively small sample size and having only two time points.

Conclusions

Female homicide in South Africa was lower in 2009 than 1999, but intimate partner femicide and suspected rape homicide rates were not statistically different. The cause of the difference is unknown. The findings suggest that South Africa needs greater efforts nationally to implement evidence-based violence prevention. Please see later in the article for the Editors'' Summary  相似文献

Sexual violence within as well as outside sexual relationships has far-reaching public health and human rights implications and is a continuing focus of popular debate, media coverage, and research in postapartheid South Africa. Partly because it has been shown to affect individual vulnerability to HIV/AIDS, sexual violence has in recent years become framed as a global public health issue. International research efforts to document the scale of this personally and politically sensitive problem can encounter conceptual, definitional, and methodological difficulties that anthropology is well placed to assist in alleviating. This article offers an ethnographic exploration of the spectrum of practices relating to sexual coercion and rape among young people in a township in the former Transkei region of South Africa. Contextualizing meanings of sexual coercion within local youth sexual culture, the article considers two emic categories associated with sex that is "forced": ukulala ngekani: "to sleep with by force" or ukunyanzela: "to force," both usually used to describe episodes occurring within sexual partnerships; and ukudlwengula, used to describe rape by a nonpartner or stranger. The article discusses the semantic content of and differences between these two key categories, demonstrating that encounters described as "forced sex" encompass not only various forms of sexual coercion but also, particularly in the narratives of young men, instances of more consensual sex. Of importance, in turn, in defining an act as "rape" rather than as "forced sex" are the character of the relationship between the two parties and interlinked ideas relating to exchange and sexual entitlement, love, and the importance of "intention," violation, and "deserving" victimhood.  相似文献
