Osteology,DNA and Sex Identification: Morphological and Molecular Sex Identifications of Five Neolithic Individuals from Ajvide,Gotland

Sex identifications are crucial for the understanding of the societies we study. To understand an ancient society we need to have some picture of the roles played by males and females in the society. This knowledge has often been produced by morphological sex identifications in connection with grave goods and burial finds. However, if a morphological sex identification is to be fully trusted, the human remains need to be fairly well preserved. There is also a problem in the fact that morphological traits identified in a modern material are applied on an ancient material. There is a growing difference with time and geographical distance. An alternative to morphological identification is molecular identification based on the presence or absence of a Y chromosome, but such identification has its problems too: the risk of contamination and the fact that the absence of proof is not a good female indicator. In this work we have tried to compare morphological and molecular identifications of five Neolithic individuals from the Ajvide site at Gotland in the Baltic sea. © 1997 by John Wiley & Sons, Ltd.     

The utility of hand and foot bones for the determination of sex and the estimation of stature in a prehistoric population from west-central Illinois

This study focuses on hands and feet as indicators of sex and stature for Native Americans, hitherto relatively neglected in this regard. The study was performed on a large, well-preserved prehistoric skeletal sample from west-central Illinois. Discriminant functions are presented which determine sex with accuracies exceeding 87%. Those functions are then tested on three other Native American samples and found to have similar high degrees of accuracy. The utility of hand and foot bones for estimation of femur length (and subsequent inclusion in stature estimation equations) is also explored. While indirect estimation of stature is determined to be possible in this manner, it is suggested that these and other stature estimation techniques that have large standard errors may be of limited archaeological or forensic value. © 1998 John Wiley & Sons, Ltd.     

Developing stages of subacromial humeral‐impingement facets in the skeletal remains of two human populations

The humeral impingement disorder (HID) results from degenerative changes in the rotator cuff tendon which allows the humerus to press against the acromion and produce pressure facets on both the acromion and the greater humeral tubercle. A previous study of those below 55 years of age in the two populations defined a system of three morphological categories of subacromial features. The first two categories were postulated to be pre‐impingement while the third, distinguished by erosive pitting at the point of attachment of the cuff to the greater tubercle, was regarded as indicative of degenerative change in the cuff and, therefore, of HID. Extending the study to those over 55 years of age has now added two categories of more advanced HID change. Those on the right side, of dominant use, were always more severe, thus enabling a less severe Category 4 to be distinguished from Category 5, the chief feature of which was a raised facet which could be large or small. Confirmation of the earlier study's conclusions was achieved: the degenerative changes of Category 3 began to be common by 40 years of age in both sexes of the Scottish island people, living physically‐stressed lives; in the more wealthy and sedentary Londoners, this does not occur until 10 years later. Nevertheless, in both sexes in both populations, virtually all those over 65 years of age showed Category 4 or 5 change. It seemed likely that a higher proportion of the Londoners reached advanced ages than among the islanders and so had more time for the progressive disorder to show its full effects; for instance, there were 16 Londoners known to be over 80 years of age. Individuals of that age cannot be distinguished by methods for estimating age from those 15 years or so younger but it was regarded as unlikely that there were more than two or three octogenarians among the islanders.

China's 100 Per Cent Condom Use Program: Customising the Thai Experience

This paper examines the adoption and roll-out of a 100 Per Cent Condom Use Program (100% CUP) in the People's Republic of China (PRC). It first details the initial implementation of a 100% CUP in Thailand and explains how this created a framework for action in other developing countries. It then examines the implementation of pilot programs in China. We conclude that governmental authorities in the PRC now actively target designated high-risk populations such as female sex workers in order to combat the spread of sexually transmissible infections and HIV/AIDS. This has resulted in the introduction of new legal frameworks and the use of widespread media publicity to promote condom use and safer-sex strategies. However, the more effective implementation of a national 100% CUP in China requires attention to the problems associated with the legal and social marginalisation of female sex workers, which is reinforced by police-led crackdowns on prostitution.     

HEALTH OF HOME-BASED SEX WORKERS AND THEIR CHILDREN IN RURAL ANDHRA PRADESH,INDIA

This study uses secondary data from 2006 to assess the physical and mental health of rural, home-based sex workers and their young children in rural Andhra Pradesh state of India. The analyses of survey and clinical data show a high level of morbidity amongst sex worker women and their children. Women show high levels of nutritional deficiencies, anaemia, weight loss and hospitalisation. Women's mental health is particularly serious, with 92 per cent being depressed and 57 per cent having attempted suicide. The majority have experienced domestic and work-related violence, including rape. Clinical assessments of sex workers’ children show that most have received vaccinations, but almost half have parasites, dental problems and nutritional deficiencies. Both the physical and mental health of sex worker mothers are associated with the health of their children. Therefore, health interventions focusing on sex worker mothers have the potential to improve the health of their children.     

Sex differences in musculoskeletal stress markers: Problems with activity pattern reconstructions

This study examined six musculoskeletal stress marker (MSM) scores that showed reverse sex differences in the previously published research. MSM scores often differ by sex within a population. Most often females have lower MSM scores than do males; however, reverse sex differences do occur. If reverse sex differences are culturally specific, then these MSM scores are more likely caused by activity patterns than biology. Yet, if the same MSM scores show reverse trends in multiple populations, then perhaps these reversals may be the result of biological sex differences, such as hormonal differences and body size, or methodological reasons, such as MSM location. In the current study, deltoideus, pronator quadratus and trapezius MSM scores were significantly more pronounced in males in the California Amerind population examined. Most MSM scores examined significantly correlated with body size and age. With articular size and age controls, only the pronator quadratus and trapezius continued to display significant sex differences. Males had greater MSM pronator quadratus and trapezius scores than did females. The lack of sex differences in four out of six MSM scores may relate to the confounding factor of body size. Thus, it is suggested that some reverse sex differences in the published literature may not relate to activity patterns whereas other MSM sites show more promise.

New Dietary Evidence on Medieval Rural Communities of the Basque Country (Spain) and Its Surroundings from Carbon and Nitrogen Stable Isotope Analyses: Social Insights,Diachronic Changes and Geographic Comparison

This paper presents the results of palaeodietary reconstruction based on stable carbon and nitrogen isotope analysis on bone collagen of five medieval rural populations from the Basque Country (northern Spain) spanning from 5^th to 15^th centuries ad . One hundred forty‐seven human and 47 domestic faunal samples were successfully analysed with the objective of defining agrarian productive strategies and food consumption patterns. The results grouped the five sites in two clusters: on one side Zaballa and Treviño, whose inhabitants followed diets exclusively based on C₃ plants with significant intake of animal protein, and on the other, the populations from Aistra and Zornoztegi, who combined C₃ and C₄ plants and consumed lower amounts of animal protein. The isotopic values from Dulantzi were intermediate to these two groups. No differences were detected when individual status markers, such as grave goods, were available. Conversely, some restrictions on the access to certain food resources based on sex were uncovered. A relevant change in δ¹³C values was identified around 10^th century, a consequence of a shift in the consumption patterns of C₃ and C₄ plants. Finally, these Basque sites were compared with those of the medieval Iberian case studies available in the literature. This comparison made evident the distinctive nature of the diet of the Basque medieval rural contexts. Copyright © 2017 John Wiley & Sons, Ltd.     

Spondylolysis in a pre‐contact San Francisco Bay population: behavioural and anatomical sex differences

Spondylolysis refers to a separation of the spinal body from the arch. Researchers have documented that these fractures occur due to stresses related to activities involving the lower limb and back. Spondylolysis in sacral and lumbar vertebrae of 146 (66 males, 66 females, 14 indeterminates) California Amerinds were examined to determine whether sex differences were present. Sacral anatomy (i.e. sacralisation and lumbarisation, sacral base angles, and superior facet morphology) was analysed in relation to spondylolysis and sex, to explore whether sex differences could be better explained through activity patterns or anatomical variation. Spondylolysis afflicted 24 individuals (16.4%). Males had more than twice the rate of spondylolysis than did females (26% and 11%, respectively). Activity patterns, such as thrusting and throwing shafted obsidian points, could explain the sex differences. Males were most frequently buried with obsidian point artefacts, whereas females were buried with mortar and pestles. For sacral anatomy, only males had lumbarisation, and all other anatomical variation had no significant sex differences. Lumbarisation related to spondylolysis in males. In this study, sacral anatomical variation could not fully account for sex differences in spondylolysis; activity patterns provided a better explanation. Nonetheless, anatomical variation may predispose males to spondylolysis, or spondylolysis may affect sacral anatomy. Copyright © 2008 John Wiley & Sons, Ltd.     

Sexual dimorphism in limb bones of ibex (Capra ibex L.): mixture analysis applied to modern and fossil data

Estimating sex ratios of fossil bone assemblages is an important step in the determination of demographic profiles, which are essential for understanding the palaeobiology and palaeoethology of any particular species, as well as its exploitation patterns by humans. This is especially true for ibex (Capra ibex), which was a main source of food for hominids during Pleistocene times. Classical methods for determining sexual dimorphism and sex ratio, such as analyses using uni‐ and bivariate plots, are based on an arbitrary fixing of limits between sexes. Here we use a more robust statistical method termed mixture analysis (MA) to determine the sex of postcranial remains (long bones, metapodials and tarsals) from ibex. For the first time, we apply MA to both a modern and a fossil sample of one species, by using metric data taken from (i) a collection of present‐day ibex skeletons and (ii) a Palaeolithic sample of the same species. Our results clearly show that the forelimb (humerus and radius) is more dimorphic than the hindlimb (femur and tibia) and is therefore better suited for sexing ibex. It also appears that metapodials should be used carefully for estimating sex ratios. On the basis of these results, we propose a classification of bone measurements that are more or less reliable for sexing ibex. The results of MA applied to the ibex fossil bones from the Upper Palaeolithic site of the Observatoire (Monaco) lead us to the conclusion that this assemblage consists of a majority of males. The quantitative estimations calculated by the MA make it possible to compare the size of Pleistocene and modern ibex for the whole set of variables used in this study.

Unpacking the landscape of female sex tourism in Kenya: a film analysis of Paradise: Love

This article examines Paradise: Love (2012, Dir. Ulrich Seidl), a compelling filmic account of the problematics of race, ethnicity, gender, and nation that organize contemporary accounts of female sex tourism. The storyline and visual imagery of the film positions Kenya – and a Eurocentric, homogenized, and reductive (mis)understanding of parts of ‘Africa’ – as an imagined site of racial and sexual adventure for older white Western women seeking intimate relationships with a category of local black men, many of whom enter into these sexual relationships in order to supplement personal and family economic shortfalls. This economy of intimate exchange is positioned as a trade of these black Kenyan men’s desire for money, local status, and the potential to travel to the West, for white Western women’s desire for sexual fulfillment from young black men’s bodies and their assumed sexual prowess. Deconstructing the discourses of female sex tourism through Paradise: Love centres the visual and representational components of processes of racialization and sexualization, wherein beach boys and white Western women gaze upon and ‘Other’ each other through essentialist and fetishized understandings of racial and sexual difference. In focusing on the power dynamics of female sex tourism in particular, the film plays up the shock value of women sexually exploiting men, pushing viewers to question: who counts as a sex tourist? Ultimately, this article seeks to enrich and extend scholarship that troubles intersecting power structures that shape and inform transnational inter-racial intimacies within economies of eroticized exchange.
