Blood Drunkenness and the Bloodthirsty Semai: Unmaking Another Anthropological Myth

The Senoi Semai of Malaysia have frequently been cited as examples in the debates over the wellsprings of human violence. Numerous writers have employed selected Semai ethnographic material to support assertions that, their apparent peacefulness notwithstanding, Semai are in reality bloodthirsty killers. This assertion has in turn been used as evidence in support of a variety of approaches whose common thread is a view of aggressiveness and violence as somehow innate in human beings. The authors of this article, whose publications form the basis of most anthropological knowledge of Semai life and culture, draw on their own published and unpublished work as well as on documentation from other sources to refute these interpretations. We hold that Semai life is, as first-hand observers have described it, notably free of interpersonal violence, and we argue that misrepresentations rooted in particular theoretical or philosophical a priori assumptions are scientifically untenable and culturally slanderous.     

Hocus Pocus and Extensionism in Central Malaya: Notes on Semai Kinship Terminology

This paper presents componential definitions of two sets of Semai kinship terminology gathered in two Semai settlements. A comparison of these definitions with each other and with Semai rules about proper terminology usage brings several inconsistencies to light. These inconsistencies seem to suggest that a modified componential analysis conforms to the cognitive categories of the Semai if the extensionist hypothesis that terms have both primary and derived meanings is taken into account.

Fission-fusion and lineal effect: aspects of the population structure of the Semai Senoi of Malaysia.

Analysis of histories and genealogies from seven relatively unacculturated, swidden-farming Semai settlements shows that the composition of local groups fluctuates through time. This instability is similar to a pattern which Neel and his colleagues have suggested is typical of primitive society, the fission-fusion model. In addition, the individuals comprising Semai fission groups are kinsmen which implies that the number of independent genomes represented is markedly less than the number of individual migrants (the lineal effect). Fission groups may form new villages or fuse with an established settlement. In either case, the genetic effects of such migration are more pronounced than would be expected on the basis of founder effect or random migration. Despite several conspicuous differences in social organization between the Semai and the South American Indians (e.g., bilateral vs. unilineal descent) whose population structure provided the empirical basis for the fission-fusion, lineal effect model, the basic similarities are striking. The Semai case thus lends support to the proposition that this pattern may be of some generality in technologically primitive populations.     

Endogamy in settlement populations of semai senoi: Potential mate pool analysis and simulation

Abstract

Two methods have been used to evaluate potential endogamy in three settlement populations of a swidden farming group, the Semai Senoi of Malaysia. One method involved determining the number of potential mates available to individuals in each population based on demographic structure and cultural rules concerning appropriate mates. A Monte Carlo simulation of Semai settlement populations was also carried out under two different regimes of mate choice. Both procedures suggest that individuals in the largest Semai settlements are potentially able to marry endogamously but that in smaller groups few potential mates are available and many persons must marry exogamously or remain unmarried. The relatively high rate of marital migration required among small settlement populations implies that newly founded small groups would be unlikely to become sufficiently isolated to form distinct breeding populations.     

Small-scale utilization of rattan by a Semai Community in West Malaysia

The role rattan plays in the life of a small Semai community in West Malaysia is discussed. Of the 24 rattan species occurring in the study area, four are frequently used for binding, housebuilding, basketry, fish traps and snares, and other artifacts. These are briefly described and some illustrated. Some species are used for food, medicinal, and ritual purposes. The Semai have a profound knowledge of nature and have a good concept of rattan systematics that comes very close to scientific classification. Demand for rattan for commercial use threatens the rattan populations and has led to heavy depletion of some of the most useful species.     

Adenosine deaminase polymorphism among the Semai, Temuan, Semelai, and Jakun groups of West Malaysian Orang Asli

812 West Malaysian Orang Asli belonging to four ethnic groups were surveyed for adenosine deaminase (ADA; EC 3.5.4.4) using starch gel electrophoresis. Only the common ADA1 and ADA2 alleles were found, with the frequencies of the latter being 0.025, 0.103, 0.115 and 0.028 in the Semai, Semelai, Temuan, and Jakun groups, respectively. A new 'breeding genetic distance' was applied to these gene frequencies and the Semelai and Temuan were found to be more closely related to each other, and to have considerably more evolutionary flexibility on this scale of 'micro-evolution' than the other two groups. The Semai and Jakun were more similar to each other on the basis of these ADA gene frequencies.     

Primitive Warfare and the Ratomorphic Image of Mankind

The most influential current explanations of preindustrial violence and warfare see it as determined by factors and forces entirely external to human beings and their motives and purposes. This article critically examines the most prominent of these approaches—behavioristic, sociobiological, and ecological-functional—and some of the assumptions underlying them. Then, drawing on ethnographic data from a society known for its peacefulness—the Semai Senoi—the article offers an alternative conception of action, one that views human behavior, including warfare and nonviolence, as purposive, and that sees human beings as active decision makers picking their ways through fields of options and constraints in pursuit of individually and culturally defined goals in a culturally constituted reality which they themselves are actively constructing.     

Changing sex ratio of mortality in the Semai Senoi, 1969-1987

An excess of male over female deaths is characteristic of modern national populations, whereas in some high-mortality societies female mortality exceeds that of males. Among the Semai Senoi, a Malaysian Orang Asli ("aboriginal") population, women experienced higher mortality than males in the decades before 1969. This differential occurred in all age classes older than 15 years so that the sex ratio progressively increased with age. A recent (1987) restudy of the Semai population found that sex-specific differential mortality is much reduced. A comparison of the 1969 and 1987 life tables shows a sharp shift in the sex ratios of mortality for the post-15-year-old age classes (the geometric means of age classes 15-44 were 0.768 in 1969 and 0.997 in 1987) so that male and female expectations of further life at age 15 are now nearly identical. In contrast to the best-known cases of high female mortality (mostly in South Asia), Semai sex differential mortality does not include the childhood ages. The Semai have traditionally been relatively sexually egalitarian, and sex bias in care has not occurred. Analysis of sex-specific causes of death for the pre-1969 population suggests that maternal mortality is the major cause of the excess female deaths. The reduced number of maternal deaths seems largely due to better health care, particularly the availability of hospital services. Interestingly, the reduction in female mortality has occurred simultaneously with increased fertility, and overall mortality has continued at relatively high levels (eO less than 36). Thus, rather than forming a component of a unitary demographic transition, declining sex differences in mortality can be accounted for by a specific factor, better maternal care.     

Genetic factors and malaria in the Temuan.

The jungle habitat of the Temuan aborigines harbors a variety of infectious diseases, the most notable being malaria. Our study of 15 genetic systems in the Temuan revealed substantial polymorphism and within-population genetic diversity. The polymorphisms for Hb beta, G6PD, and El are of interest in regard to genetic adaptation to malaria. Among the polymorphisms investigated we conclude that G6PD deficiency and elliptocytosis are likely to have malaria-resistant effects as evidenced by their low association with malarial parasitemia or their higher frequency in adults than in children. These findings suggest that the malarial habitat of the Temuans is livable in the long range sense for them because of the cluster of malaria-resistant alleles in their gene pool (G6PD)-, El, and possibly, but not tested here because of its low frequency, Hb beta E). The same condition probably holds for the Semai, the nearest aborigine neighbors of the Temuan (although the Semai have not been tested for malarial parasitemia and for these polymorphisms simultaneously), since the Semai have substantial Hb betaE, G6PD-, and El. The Temuan have a cultural identity system of rituals, beliefs, and certain aspects of language which effectively isolates them genetically from Malays and other nonaborigines. This system hinders the dilution of the malaria-resistant alleles of the Temuan gene pool with the malaria-susceptible alleles of the nonaborigine gene pools.     

Genetic microdifferentiation in the Semai Senoi of Malaysia.

Blood samples, demographic and cultural data were collected from seven settlements of Semai Senoi, a swidden farming ethnic group of Malaysia. Three genetic loci (ABO blood group, hereditary ovalcytosis, and hemoglobin) were analyzed in a total sample of 546 individuals. These data indicate a considerable degree of genetic microdifferentiation in this area of the Semai distribution. Parent-offspring birthplace data (analyzed by means of a migration matrix) and settlement histories show that settlements are not strongly isolated. Genetic differences in the study area demonstrate a reasonable correspondence with migration and the history of the settlements. Genetic convergence also occurs through the addition of migrant groups to established populations leading to new patterns of marriage between donor and recipient groups. The genetic structure of the total Semai population through time thus comprises a mosaic of shifiting allele frequencies in a series of semi-isolated local populations.     

Physical Violence against General Practitioners and Nurses in Chinese Township Hospitals: A Cross-Sectional Survey

Purpose

The purpose of this study is to identify risk factors of physical violence in Chinese township hospitals.

Methods

A cross-sectional survey was used in a sample of 442 general practitioners and 398 general nurses from 90 township hospitals located in Heilongjiang province, China (response rate = 84.8%).

Results

A total of 106 of the 840 (12.6%) respondents reported being physically attacked in their workplace in the previous 12 months. Most perpetrators were the patients’ relatives (62.3%), followed by the patient (22.6%); 73.6% of perpetrators were aged between 20 and 40 years. Of the physical violence incidents, about 56.6% (n = 60) resulted in a physical injury, and 45.4% of respondents took two or three days of sick leave. Reporting workplace violence in hospitals to superiors or authorities was low (9.4%). Most respondents (62.8%) did not receive training on how to avoid workplace violence. Logistic regression analyses indicated that general nurses, aged 35 years or younger, and with a higher-level professional title were more likely to experience physical violence. Healthcare workers with direct physical contact (washing, turning, lifting) with patients had a higher risk of physical violence compared to other health care workers. Procedures for reporting workplace violence were a protective factor for physical violence; when in place, reporting after psychological violence (verbal abuse, bullying/mobbing, harassment, and threats) was more protective than waiting until an instance of physical violence (beating, kicking, slapping, stabbing, etc.).

Conclusions

Physical violence in Chinese township hospitals is an occupational hazard of rural public health concern. Policies, procedures, and intervention strategies should be undertaken to manage this issue.     

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.     

Trauma and violence in the Wari empire of the Peruvian Andes: warfare, raids, and ritual fights

This study examines bioarchaeological evidence for violence during the period of Wari imperialism in the Peruvian Andes through analysis of skeletal trauma from three populations dating to AD 650-800. The samples are from contemporaneous archaeological sites: Conchopata, a Wari heartland site in central highland Peru; Beringa, a community of commoners in the Majes valley of the southern Wari hinterland; and La Real, a high status mortuary site, also in the Majes valley. Given the expansionist nature of Wari and its military-related iconography and weaponry, it is hypothesized that Wari imperialism was concomitant with greater levels of violence relative to other prehispanic groups in the Andes. It is also hypothesized that differential articulation with the Wari empire (e.g., heartland vs. hinterland groups) affected the frequency and patterning of trauma. Results show that cranial trauma frequency of the three Wari era samples is significantly greater than several other Andean skeletal populations. This suggests that Wari rule was associated with high levels of violence, though it may not have always been related to militarism. The three adult samples show similar frequencies of cranial trauma (Conchopata = 26%; Beringa = 33%; La Real = 31%). This may suggest that differential positioning in the Wari empire had little effect on exposure to violence. Sex-based differences in cranial trauma frequencies are present only at La Real, but wound patterning differs between the sexes: females display more wounds on the posterior of the cranium, while males show more on the anterior. These data suggest that Wari rule may have contributed to violence.     

Effect of Physical Violence on Sexually Transmitted Infections and Treatment Seeking Behaviour among Female Sex Workers in Thane District,Maharashtra, India

Background

Violence against sex workers can heighten their vulnerability to HIV and other sexually transmitted infections (STIs). Evidence suggests the risk of acquiring STI/HIV infections among female sex workers (FSWs) who have experienced violence to be almost three-times higher than FSWs, who have not experienced violence. Moreover, an experience of physical and sexual violence makes it difficult for them to negotiate safer sex with their partners and often act as a barrier to utilization of prevention services.

Methods

This study utilizes data from 2785 FSWs aged 18 years and above who participated in a cross-sectional behavioural study conducted during 2013–14 in Thane district, Maharashtra. A probability-based two-stage cluster sampling method was used for data collection. This study assesses the effect of physical violence on self-reported STI symptoms (any STI and multiple STIs) and treatment seeking for the last STI symptom using propensity score matching method.

Results

About 18% of sampled FSWs reported physical violence at the time of the survey. The likelihood of experiencing such violence was significantly higher among FSWs who solicited clients at public places, engaged in other economic activities apart from sex work, had savings, and reported high client volume per week. FSWs experiencing violence were also inconsistent condom users while engaging in sex with regular partners and clients. The average adjusted effect of violence clearly depicted an increase in the risk of any STI (11%, p<0.05) and multiple STIs (8%, p<0.10) and reduction in treatment seeking (10%, p<0.05).

Conclusions

This study demonstrates a significant effect of physical violence on reporting of any STI symptom and treatment seeking. Findings call for the immediate inclusion of strategies aimed to address violence related challenges in HIV prevention program currently being provided at Thane district. Such strategies would further help in enhancing the access to tailored STI prevention and care services among FSWs in the district.     

Kin groups and trait groups: population structure and epidemic disease selection

A Monte Carlo simulation based on the population structure of a small-scale human population, the Semai Senoi of Malaysia, has been developed to study the combined effects of group, kin, and individual selection. The population structure resembles D.S. Wilson's structured deme model in that local breeding populations (Semai settlements) are subdivided into trait groups (hamlets) that may be kin-structured and are not themselves demes. Additionally, settlement breeding populations are connected by two-dimensional stepping-stone migration approaching 30% per generation. Group and kin-structured group selection occur among hamlets the survivors of which then disperse to breed within the settlement population. Genetic drift is modeled by the process of hamlet formation; individual selection as a deterministic process, and stepping-stone migration as either random or kin-structured migrant groups. The mechanism for group selection is epidemics of infectious disease that can wipe out small hamlets particularly if most adults become sick and social life collapses. Genetic resistance to a disease is an individual attribute; however, hamlet groups with several resistant adults are less likely to disintegrate and experience high social mortality. A specific human gene, hemoglobin E, which confers resistance to malaria, is studied as an example of the process. The results of the simulations show that high genetic variance among hamlet groups may be generated by moderate degrees of kin-structuring. This strong microdifferentiation provides the potential for group selection. The effect of group selection in this case is rapid increase in gene frequencies among the total set of populations. In fact, group selection in concert with individual selection produced a faster rate of gene frequency increase among a set of 25 populations than the rate within a single unstructured population subject to deterministic individual selection. Such rapid evolution with plausible rates of extinction, individual selection, and migration and a population structure realistic in its general form, has implications for specific human polymorphisms such as hemoglobin variants and for the more general problem of the tempo of evolution as well.     

Frequency and patterning of bone trauma in the late medieval population (13th-16th century) from Dugopolje, southern Croatia

The aim of this paper is to test the hypothesis of an increased level of interpersonal violence in Dugopolje during the late medieval period as testified by written sources. In order to accomplish this, an analysis and comparison of frequencies and patterning of long bone and craniofacial fractures between sex and age categories in the Dugopolje skeletal sample was performed. In total 209 excellently preserved adult skeletons were analysed: 111 males and 98 females. The total long bone fracture frequency is 1.5% (29/1910) with a significantly higher frequency in males compared to females. Most of the long bone injuries occurred as a result of accidents, probably due to rugged mountainous terrain, while a certain portion of trauma resulted from deliberate violence. Significantly higher fracture frequencies in males could be a result of a strict sexual division of labour where males performed more physically demanding and risky tasks, as witnessed by historical sources. 26 out of 119 complete adult crania (21.8%) exhibit skeletal trauma with significantly higher frequencies in males. Perimortem trauma was observed in one individual while antemortem healed sharp force lesions were registered in five individuals (all males). The predominance of frontal craniofacial injuries, as well as the presence ofperimortem trauma and sharp force lesions, suggests the presence of deliberate violence in this community. Although the indicators of deliberate violence were recorded predominantly in males, suggesting that intentional violence in Dugopolje was exclusively males' prerogative, the presence of nasal fracture in a female skeleton might point to a male towards female violence. Presented bioarchaeological data are in accordance with the written documents thus corroborating the claims of an increased level of deliberate interpersonal violence in the late medieval population from Dugopolje.     

Contraception use and associations with intimate partner violence among women in Bangladesh

This study examines the association between contraception use and intimate partner violence (IPV) among women of reproductive age in Bangladesh. The observational study of 10,996 women used the chi-squared test and logistic regressions to assess the associations. Almost 80% of all respondents had used contraceptives at some point in their lives. About half of the respondents (48%) were victims of physical violence, while 11% experienced sexual abuse from their husbands. Urban residents, higher educated women and women aged 20-44 were more likely to use contraceptives than their peers in rural areas, those with lower education and those in their late forties (45-49 years). Women exposed to physical violence were almost two times (OR 1.93, CI 1.55-2.41) more likely to use contraceptives compared with their non-abused peers. Sexual abuse had no significant association with contraceptive use. Physical violence is a predictor for higher levels of contraceptive use among women in Bangladesh. The findings emphasize the importance of screening for IPV at health care centres. The differences in urban and rural contraceptive use and IPV exposure identified by the study have policy implications for service delivery and planning.     

From John McCain to Abu Ghraib: Tortured Bodies and Historical Unaccountability of U.S. Empire

ABSTRACT   John McCain, once considered a "friend" of Vietnam because of his support for normalized relations with the United States, has since lost his standing. Claims to inhumane treatment and torture while a prisoner in the "Hanoi Hilton" have met with angry denials and calls for more attention to the humanitarian care that McCain and others received. Recent U.S. allegations of human rights abuses in Vietnam following the Abu Ghraib prison scandal have further strained relations, as have charges leveled against Vietnamese small-scale producers of dishonest trade practices. Drawing on these exchanges, I examine competing representations of Vietnamese wartime acts that have permeated the "normalization" process. Neoliberal rhetorics aimed at "saving" the Vietnamese economy and its allegedly blemished human rights record are countered by discourses and images that lay claim to a Vietnamese "tradition" of wartime compassion and humanitarianism that also demands U.S. historical accountability for imperial violence and its aftermaths.

Investigating Exposure to Violence and Mental Health in a Diverse Urban Community Sample: Data from the South East London Community Health (SELCoH) Survey

Background

General population surveys have seldom examined violence as a multidimensional concept and in relation to an array of mental disorders.

Methods

Data from the South East London Community Health Study was used to examine the prevalence, overlap and distribution of proximal witnessed, victimised and perpetrated violence and their association with current mental disorders. We further investigated the cumulative effect of lifetime exposure to violence on current mental disorders. Unadjusted and adjusted (for confounders and violence) models were examined.

Results

In the last twelve months, 7.4% reported witnessing violence, 6.3% victimisation and 3.2% perpetration of violence. There was a significant overlap across violence types, with some shared correlates across the groups such as being younger and male. Witnessing violence in the past year was associated with current common mental disorders (CMD) and post-traumatic stress disorder (PTSD) symptoms. Proximal perpetration was associated with current CMD, PTSD symptoms and past 12 months drug use; whereas proximal victimisation was associated with lifetime and past 12 months drug use. Lifetime exposure to two or more types of violence was associated with increased risk for all mental health outcomes, suggesting a cumulative effect.

Conclusion

Exposure to violence needs to be examined in a multi-faceted manner: i) as discrete distal and proximal events, which may have distinct patterns of association with mental health and ii) as a concept with different but overlapping dimensions, thus also accounting for possible cumulative effects.     

Genetic variation at 9 autosomal microsatellite loci in Asian and Pacific populations.

Genetic variation at 9 autosomal microsatellite loci (CFS1R, TH01, PLA2A, F13A1, CYP19, LPL, D20S481, D20S473, and D20S604) has been characterized in 16 Asian and Oceanic populations, mostly from mainland and insular Southeast Asia. The neighbor-joining tree and the principal coordinates analysis of the genetic relationships of these populations show a clear separation of Papua New Guinea Highlanders and, to a lesser extent, Malayan aborigines (Orang Asli or Semai) from the rest of the populations. Although the number of markers used in this study appears to be inadequate for clarifying the patterns of genetic relationships among the studied populations, in the principal coordinates analysis a geographic trend is observed in the mainland and insular Southeast Asian populations. Furthermore, in an attempt to contrast the extent of variation between autosomal and Y-chromosome-specific microsatellite loci and to reveal potential differences in the patterns of male and female migrations, we have also compared genetic variation at these 9 autosomal loci with variation observed at 5 Y-chromosome-specific microsatellites in a common set of 14 Asian populations.
