This work identifies and describes pathological skeletal changes associated with and attributable to acquired syphilis and which potentially caused functional impairment within eleven skeletal individuals recovered from five industrial-era London cemeteries. In eight (72.73%), functional impairment was likely or very likely, based on type and distribution of lesions across their skeleton. These impairments likely impacted the individuals’ ability to engage in various forms of physical activity, potentially limiting their economic potential. These results expand our still highly limited understanding of syphilis’s functional impacts within past populations, especially within industrial-era societies, querying longstanding characterizations of tertiary gummatous involvement as benign, while encouraging paleopathological investigations of the functional impacts of syphilis in past populations in which the disease was endemic, such as industrial-era England. Further, with syphilis rates on the rise globally, this information may be informative prognostically for present-day clinical cases of primary to tertiary stage undiagnosed and/or untreated syphilis.

<p>In chimpanzees, most females disperse from the community in which they were born to reproduce in a new community, thereby eliminating the risk of inbreeding with close kin. However, across sites, some females breed in their natal community, raising questions about the flexibility of dispersal, the costs and benefits of different strategies and the mitigation of costs associated with dispersal and integration. In this dissertation I address these questions by combining long-term behavioral data and recent field observations on maturing and young adult females in Gombe National Park with an experimental manipulation of relationship formation in captive apes in the Congo.</p><p>To assess the risk of inbreeding for females who do and do not disperse, 129 chimpanzees were genotyped and relatedness between each dyad was calculated. Natal females were more closely related to adult community males than were immigrant females. By examining the parentage of 58 surviving offspring, I found that natal females were not more related to the sires of their offspring than were immigrant females, despite three instances of close inbreeding. The sires of all offspring were less related to the mothers than non-sires regardless of the mother’s residence status. These results suggest that chimpanzees are capable of detecting relatedness and that, even when remaining natal, females can largely avoid, though not eliminate, inbreeding.</p><p>Next, I examined whether dispersal was associated with energetic, social, physiological and/or reproductive costs by comparing immigrant (n=10) and natal (n=9) females of similar age using 2358 hours of observational data. Natal and immigrant females did not differ in any energetic metric. Immigrant females received aggression from resident females more frequently than natal females. Immigrants spent less time in social grooming and more time self-grooming than natal females. Immigrant females primarily associated with resident males, had more social partners and lacked close social allies. There was no difference in levels of fecal glucocorticoid metabolites in immigrant and natal females. Immigrant females gave birth 2.5 years later than natal females, though the survival of their first offspring did not differ. These results indicate that immigrant females in Gombe National Park do not face energetic deficits upon transfer, but they do enter a hostile social environment and have a delayed first birth. </p><p>Next, I examined whether chimpanzees use condition- and phenotype-dependent cues in making dispersal decisions. I examined the effect of social and environmental conditions present at the time females of known age matured (n=25) on the females’ dispersal decisions. Females were more likely to disperse if they had more male maternal relatives and thus, a high risk of inbreeding. Females with a high ranking mother and multiple maternal female kin tended to disperse less frequently, suggesting that a strong female kin network provides benefits to the maturing daughter. Females were also somewhat less likely to disperse when fewer unrelated males were present in the group. Habitat quality and intrasexual competition did not affect dispersal decisions. Using a larger sample of 62 females observed as adults in Gombe, I also detected an effect of phenotypic differences in personality on the female’s dispersal decisions; extraverted, agreeable and open females were less likely to disperse. </p><p>Natural observations show that apes use grooming and play as social currency, but no experimental manipulations have been carried out to measure the effects of these behaviors on relationship formation, an essential component of integration. Thirty chimpanzees and 25 bonobos were given a choice between an unfamiliar human who had recently groomed or played with them over one who did not. Both species showed a preference for the human that had interacted with them, though the effect was driven by males. These results support the idea that grooming and play act as social currency in great apes that can rapidly shape social relationships between unfamiliar individuals. Further investigation is needed to elucidate the use of social currency in female apes.</p><p>I conclude that dispersal in female chimpanzees is flexible and the balance of costs and benefits varies for each individual. Females likely take into account social cues present at maturity and their own phenotype in choosing a settlement path and are especially sensitive to the presence of maternal male kin. The primary cost associated with philopatry is inbreeding risk and the primary cost associated with dispersal is delay in the age at first birth, presumably resulting from intense social competition. Finally, apes may strategically make use of affiliative behavior in pursuing particular relationships, something that should be useful in the integration process.</p> / Dissertation

The goal of this dissertation is to discuss relationships between the sociocultural environment and nutritional status outcomes in an urban industrialized city with high rates of poverty. The purpose is to highlight the complex web of factors shaping nutritional status outcomes and move beyond cause and effect approaches to nutrition in an environment where obesity is a central nutritional concern. To accomplish this goal, I examine a range of factors that relate to adolescent nutritional practices and nutritional status outcomes in a sample population of adolescents living in Belfast, Northern Ireland. I discuss connections between social locations such as age, gender, geographic area, and socioeconomic status. I also highlight the range of nutritional status outcomes observed in the sample population, while examining broader social, political, and economic aspects of the lives of adolescents that differentially shape nutrition-related experiences in the city. Finally, I demonstrate that adolescents occupy a complex social location in which autonomy, advice, and influence from sociocultural and political-economic factors shape their diet and exercise practices and nutritional status outcomes in multi-faceted, and at times unexpected, ways. In doing so, I emphasize the benefits of a localized, rather than a globalized approach to nutritional concerns such as obesity.

<p>During the last six million years, humans shifted from a primarily arboreal lifestyle to a habitually bipedal, terrestrial lifestyle. Australopithecus had a significant bipedal component to its locomotion; whether suspensory and climbing behavior were also important has remained unclear. Morphological features of the forelimb have been linked to locomotor differences among primates, but the interpretation of human fossils has remained problematic.</p><p>This dissertation examined the total morphological pattern of the forelimb, specifically the functional integration of the musculature and joint systems. This approach employed both geometric morphometrics and a biomechanical modeling approach to studying how and how well the forelimb morphology of living suspensory and quadrupedal primates, as well as humans and fossil hominins, accommodate climbing and suspensory locomotion. Data collected with a microscribe 3-D digitizer on the scapula, humerus, radius, and ulna of Australopithecus sediba, Australopithecus afarensis, and Homo erectus were compared to a sample of Homo sapiens, Pan troglodytes, Pan paniscus, Gorilla gorilla, Pongo pygmaeus, Hylobates lar, and Macaca fuscicularis.</p><p>The hominin upper limb is a rich mosaic of primitive and derived traits. The blade of Australopithecus sediba, although appearing most similar to extant orangutans, is in fact functionally most similar to chimpanzees. The overall morphology of the australopith elbow joint appears most similar to Pan, as does the elbow joint of Homo erectus, suggesting that the modern human configuration happened more recently than 1.5 million years ago. </p><p>Au. afarensis and Au. sediba share important similarities, but are clearly distinct species. While their overall elbow joint shape is strikingly similar, the articular surface is not identical. Au. afarensis is more similar in this respect to Pan and Homo, while Au. sediba is more similar to extant taxa that spend substantially more time engaging in vertical climbing and suspensory behavior.</p><p>The results from this study support previous interpretations that not all australopiths across time were employing the same locomotor repertoire. While this study does not present unambiguous conclusions regarding early hominin arboreal locomotion, this study suggests that the morphology of the upper limb is varied, and caution must be taken when interpreting single skeletal elements in the hominin fossil record.</p> / Dissertation

Diagnosing the sex of subadult skeletal material is a difficult task for bioarchaeologists and forensic anthropologists. Metric and nonmetric techniques have been tested utilizing both fetal (Boucher 1957, Weaver 1980) and juvenile (Loth and Henneberg 2001, Weaver 1980) skeletal remains. Some metric techniques show promise in estimating the sex of juvenile skeletons, but most are found to be lacking in adequate accuracies (Holcomb and Konigsberg 1995, Weaver 1980). Nonmetric techniques have been found to be more accurate, performing better than chance (Loth and Henneberg 2001, Mittler and Sheridan 1992, Weaver 1980). This study adds to this conversation, utilizing the Hamann-Todd Osteological Collection at the Cleveland Museum of Natural History, testing the accuracy of eight nonmetric traits of the subadult mandible and ilium for use in forensic investigations and bioarchaeological research. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2015. / FAU Electronic Theses and Dissertations Collection

This project explores the reliability of building a biological profile for an unknown individual based on three-dimensional (3D) images of the individual's skeleton. 3D imaging technology has been widely researched for medical and engineering applications, and it is increasingly being used as a tool for anthropological inquiry. While the question of whether a biological profile can be derived from 3D images of a skeleton with the same accuracy as achieved when using dry bones has been explored, bigger sample sizes, a standardized scanning protocol and more interobserver error data are needed before 3D methods can become widely and confidently used in forensic anthropology. 3D images of Computed Tomography (CT) scans were obtained from 130 innominate bones from Boston University's skeletal collection (School of Medicine). For each bone, both 3D images and original bones were assessed using the Phenice and Suchey-Brooks methods. Statistical analysis was used to determine the agreement between 3D image assessment versus traditional assessment. A pool of six individuals with varying experience in the field of forensic anthropology scored a subsample (n = 20) to explore interobserver error. While a high agreement was found for age and sex estimation for specimens scored by the author, the interobserver study shows that observers found it difficult to apply standard methods to 3D images. Higher levels of experience did not result in higher agreement between observers, as would be expected. Thus, a need for training in 3D visualization before applying anthropological methods to 3D bones is suggested. Future research should explore interobserver error using a larger sample size in order to test the hypothesis that training in 3D visualization will result in a higher agreement between scores. The need for the development of a standard scanning protocol focusing on the optimization of 3D image resolution is highlighted. Applications for this research include the possibility of digitizing skeletal collections in order to expand their use and for deriving skeletal collections from living populations and creating population-specific standards. Further research for the development of a standard scanning and processing protocol is needed before 3D methods in forensic anthropology are considered as reliable tools for generating biological profiles.

In this dissertation, I examine a former sixties era hippie commune from the things and memories its residents have left behind. I focus on the intersections of memories, materialities, identities and systems of signification in order to suggest the following: that we might consider through archaeological, anthropological, and oral historical analyses the value of a genealogy of the sixties alongside histories of the era; that plastic presents a challenging archaeological issue (one of method and curation) while simultaneously reifying a social sense of its artificiality as an artifact of New Buffalo and a present-fact of speech (i.e. referring metaphorically to things as ‘plastic’, meaning false or artificial); that considerations of a ‘hippie’ work ethic might be productively brought to bear upon contemporary concerns about work and labor, but also might unpack our understandings of work and labor in American history; that playing primitive is a performance of citation and appropriation, a process of the inauthentic mimesis creating an authentic new (problematic) identity; and that artifacts and other objects shape (even re-appropriate) memories as much as they are re-made by them, and that recent historical artifacts can open up interesting collaborative analytical spaces when brought into actual conversation with site inhabitants, residents, and visitors. I aim to synthesize a number of threads, a number of different thought clusters throughout this dissertation in an effort to unpack anew questions of authenticity, of performing primitive as a kind of ‘Indian play’, or cultural appropriation, while also articulating a kind of identity creation that is aesthetic, political and counter to hegemonic and dominant traditions and forms. This work combines original field research at the site of New Buffalo commune in Arroyo Hondo, NM (in Taos County) and among the New Buffalos.

abstract: The Egyptian New Kingdom city of Akhetaten (modern: Tell el-Amarna, el-Amarna, or simply Amarna) provides a unique opportunity to study ancient biocultural dynamics. It was a disembedded capital removed from the major power bases of Memphis and Thebes that was built, occupied, and abandoned within approximately 20 years (c. 1352–1336 BCE). This dissertation used the recently excavated Amarna South Tombs cemetery to test competing models for the development of disembedded capitals, such as the geographic origin of its migrants and its demographic structure in comparison to contrastive models for the establishment of settlements. The degree to which biological relatedness organized the South Tombs cemetery was also explored. The results suggest that the Nile Valley into the New Kingdom (1539–1186 BCE) was very diverse in dental cervical phenotype and thus highly mobile in respects to gene flow, failing to reject that the Amarna city was populated by individuals and families throughout the Nile Valley. In comparison, the Amarna South Tombs cemetery contained the least amount of dental phenotypic diversity, supporting a founder effect due to migration from larger, more diverse gene pools to the city or the very fact that the city and sample only reflect a 20-year interval with little time to accumulate phenotypic variation. Parts of the South Tombs cemetery also appear to be organized by biological affinity, showing consistent and significant spatial autocorrelation with biological distances generated from dental cervical measurements in male, female, and subadult (10–19 years of age) burials closest to the South Tombs. This arrangement mimics the same orderliness in the residential areas of the Amarna city itself with officials surrounded by families that supported their administration. Throughout the cemetery, adult female grave shaft distances predict their biological distances, signaling a nuclear family dynamic that included many females including mothers, widows, and unwed aunts, nieces, and daughters. A sophisticated paleodemographic model using simulated annealing optimization projected the living population of the South Tombs cemetery, which overall conformed to a transplanted community similar to 19th century mill villages of the United States and United Kingdom. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2018

abstract: As the junction between the head and the trunk, the neck functions in providing head stability during behaviors like feeding to facilitating head mobility during behavior like grooming and predator vigilance. Despite its importance to these vital behaviors, its form and function remain poorly understood. Fossil hominin cervical vertebrae preserve a striking diversity in form despite the commitment to orthograde bipedality. Do these differences in cervical vertebral form correspond to functional variations among our recent ancestors? This dissertation attempts to understand 1) how does the neck function in head stability and mobility 2) how do these functions relate to cervical vertebral form. Kinematic and passive range of motion studies were conducted in several species of primate to obtain measures of function which were subsequently related to skeletal form. Results show that cervical vertebral morphology does not significantly covary with differences in joint mobility. Rather, they implicate the critical role of ligaments and muscles in facilitating head mobility. Results of the kinematics study show that the neck plays a role in maintaining head stability during locomotion. However, the kinematic data do not significantly correlate with morphological variation among primate species. Given the negative results of the extant morphological analyses, it is difficult to apply them to the fossil record. As such, the functional significance of the disparate morphologies found in the hominin fossil record remain ambiguous. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2019
