Intrinsic Factors Affecting Decomposition Changes in Archaeological Head Hair from Kellis 2 Cemetery, Dakhleh Oasis, Egypt

Cole, Kathleen 01 January 2017 (has links)
Post-mortem hair root degradation, and associated characteristics such as post-mortem root banding, brush-like ends, and hard keratin points, has remained a little understood phenomenon in the forensics discipline since its discovery in the 1800's. At present, the underlying causes of these characteristics are still unknown. In addition, there is no standardization for preparing samples for forensic or archaeological analysis. In this study, 1200 hairs from a total of 51 individuals (males, n = 22; females, n = 29) ranging in age from 16 to 60+ and interred at the Kellis 2 cemetery in the Dakhleh Oasis, Egypt are examined microscopically for evidence of post-mortem hair root degradation. These remains date from ~50AD to ~450AD, and all were naturally mummified. The purposes of this thesis are two-fold; 1) to determine the efficacy of two preparation methods, and 2) to examine the intrinsic and extrinsic variables in each hair in order to ascertain the factors that affect the degradation of the human hair root after death. The preparation methods include a dry sample, where the hair is directly removed from the scalp tissue using tweezers, and a wet sample, where a 1cm portion of the scalp was first rehydrated using dimethyl sulfoxide (DMSO) for 48 hours before the hairs were extracted. Results indicate that when working with naturally mummified remains the wet method provides for easier acquisition of the sample and less chance of breakage before the hair is mounted for observation. This, therefore, provides a larger sample size for analysis. Each hair was observed using polarizing microscopy to determine whether postmortem root degradation was present, the growth stage of the hair, color, pigment density and distribution, pigment aggregate size and shape, medulla continuity and opacity, cuticle scale profile and thickness, inner cuticle margin, and the presence of ovoid bodies. Significant correlations were found between the incidence of postmortem root degradation and the growth stage, hair color, cuticle thickness, cuticle scale profile, and individual's age. The remaining variables did not show any significant correlations.

Preliminary Investigation into Biological Sex Estimation Using Trace Element Analysis in Human Hair

Woltering, Abigail 01 January 2016 (has links)
In forensic anthropology the estimation of biological sex of unidentified human remains is critical, as it essentially halves the number of potential identities. Sex estimation is also important in bioarchaeology, because the creation of the biological profile is critical to the interpretation of different sociocultural aspects of past populations. Furthermore, certain aspects of the biological profile are sex specific, so it is important to be able to accurately determine biological sex (France 1998). Typically, biological sex is estimated by assessing sexually dimorphic differences within the pelvis and skull. However, because sexually dimorphic differences arise during puberty it is difficult, and oftentimes impossible, to use these traditional techniques on juveniles. Recently, human hair has gained prominence in anthropological research. This is particularly evident in bioarchaeology, where hair can be used to discern information concerning health, toxicology, culture, and diet of past populations. This study focuses on the relationship between the content of trace elements in hair and biological sex to determine if biological sex can be assessed from the content of trace elements in human head hair. Hair was collected from three human sample groups: modern living individuals, modern cadavers, and archaeological remains. Data on trace elements was collected using laser-induced breakdown spectroscopy (LIBS). The statistical relationship between the content of trace elements and sex was then analyzed using a multivariate analysis of variance (MANOVA), post-hoc analysis of variance (ANOVAs), and stepwise binary logistic regression. The MANOVA revealed a statistically significant multivariate main effect for sample group using mean values (p-value lt& 0.0001) and mean variance values (MVs) (p-value = 0.018). Given the significant results of the MANOVA test, the univariate main effects were examined with post-hoc ANOVA tests. Significant univariate main effects were obtained for mean values for C/Mg (p-value lt& 0.0001), C/Fe (p-value lt& 0.0001), C/Ca (p-value lt& 0.0001), and C/Sr (p-value lt& 0.0001). Significant univariate main effects were obtained for MVs for C/Mg (p-value = 0.016), C/Fe (p-value = 0.010), and C/Sr (p-value = 0.042). These preliminary results demonstrate that biological sex of humans can be accurately estimated through trace elemental analysis approximately 85% of the time in living samples, and 79% of the time overall. The results also demonstrate the viability of this technique for sex estimation in juvenile remains with approximately 83% success in predicting juvenile biological sex. This sets the stage establishing trace elemental analysis of hair as a technique for estimating biological sex which is critical to forensic individuation and identification as well as further contextualization of archaeological remains.

Whetting Their Appetite: A Spatial Analysis of Seasonal Flooding and Raised Field Agriculture in the Llanos de Mojos, Bolivia

Martin, Samuel A. 01 January 2018 (has links)
The Llanos de Mojos, a region of the southwestern Amazon, is a seasonally flooded savannah located in the Beni department of Bolivia. The area sustained a significant pre-Columbian population up to the arrival of Jesuit missionaries in the late 17th century. Local communities constructed agricultural landscape modifications to help cultivate crops such as maize, manioc, and sweet potato. Raised fields contributed to soil nutrient intensification and helped to manage flooding. This study examines the relationship between 40,766 raised agricultural fields which were digitized by the Proyecto SIG Arqueologico del Beni using Google Earth and maps of surface flood coverage. Flood maps from 2012–2016 were analyzed using 14-day aggregates of Moderate Resolution Imaging Spectroradiometer (MODIS) data provided by the Dartmouth Flood Observatory. These datasets were compared using ArcGIS to examine the extent and variability of yearly flooding as well as the number of raised fields which were subject to seasonal inundation on a year-by-year basis. It was found that despite significant portions of the region being covered by seasonal floods, only 5.79% of the fields were exposed to flooding in total. This study concluded that raised fields were more suited to the containment and dispersion of localized precipitation rather than the dispersion of riverine flooding. Several fields that have paleobotanical associations with maize, manioc, and sweet potato cultivation only experience flooding for 1 out of the 5 years analyzed, supporting their practicality for growing water-sensitive crops.

Investigations of Possible Cases of Scurvy in Juveniles from the Kellis 2 Cemetery in the Dakhleh Oasis, Egypt, Through Stable Carbon and Nitrogen Isotopic Analysis of Multiple Tissues

Chasse, Georgina 01 January 2018 (has links)
Vitamin C deficiency, or scurvy, is a disease that can occur in humans at any age and has been seen throughout time. Scurvy affects the production of connective tissues, including collagen, which leads to the many symptoms of the disease, including fatigue, anemia, bleeding gums and lost teeth, skeletal changes, and even death. The Kellis 2 cemetery in the Dakhleh Oasis, Egypt, in use from approximately AD 50-360, contains the remains of many juveniles who exhibit skeletal indicators of scurvy. Tissue samples from juveniles who did (n=31) and did not (n=117) exhibit skeletal indicators of scurvy were analyzed isotopically, with the sample including stable carbon (δ13C) and nitrogen (δ15N) isotope values of bone collagen (scurvy =11, non-scurvy =13), hair (scurvy=21, non-scurvy=112), nail (scurvy =10, non-scurvy =44), and skin (scurvy =19, non-scurvy =59). Intra-tissue comparisons were conducted to determine whether this disease affects δ13C and δ15N values sufficiently to distinguish these two groups from one another isotopically. Inter-tissue comparisons between bone collagen and hair were also conducted, with emphasis placed on inter-tissue spacing results and outliers. Mean δ13C and δ15N values for each hair segment were compared to look for early isotopic signals of scurvy. No statistically significant differences were found between any intra-tissue scurvy and non-scurvy cohorts and no obvious indications of the onset of scurvy were seen in the hair segment analyses. The inter-tissue spacing results, however, highlighted some interesting patterns in the bone collagen-to-hair values, especially in regards to the identified outliers that are discussed in more detail. While this study did not detect any significant differences between scurvy and non-scurvy cohorts or early isotopic signals of the disease in hair segments, the inter-tissue spacing results do point to changes between the cohorts that may be attributable to the physiological stress of scurvy and therefore warrants further investigation.

Against the Flow: A Nineteenth Century Watermill in Central Florida

Chance Campbell, Elizabeth 01 January 2017 (has links)
Small community watermills in Central Florida have gone virtually undocumented archaeologically and little is known about them except for written historical accounts. In an effort to determine how a settler in 1866 Florida would have used prior technological knowledge to design, build, and use a watermill I used a GIS predictive model to locate a previously undocumented watermill built in what is now Seminole County Florida. After the mill was located, excavations were conducted to determine the size of the mill structures, the industrial capacity of the mill, and determine the construction methods employed to build the mill.

Crafting Craft Beer Brands: An Examination of identity, Community, and Growth in Orlando Area Craft Breweries

Fehribach, Dylan 01 January 2017 (has links)
Beer is a commodity that has been produced and consumed by humans for millennia. Within the U.S., the craft beer industry has grown considerably over the last decade, accounting for 19% of all beers sales in 2014. Despite this increased market presence, craft beer marketing and production has received little anthropological consideration. To address this dearth of case studies, I consider the local craft brewery scene, or area of activity, in Orlando Florida. My 2016 ethnographic research reveals that the local craft brewery scene exhibits both variation in identity and community locations. Interactions among breweries present opportunities for local breweries to build and grow their brands. Collected data elucidate the choices and decisions that craft brewery operators consider when producing beer, developing facilities, and promoting their beers and brand images. I conclude that the breweries create brand identity and grow their customer base and distribution through planned decisions as well as reactionary choices based on outside events. Such considerations are relevant for understanding the formation of a business's identity and brand identity while producing a craftwork product, as well the communities of each brewery interact with communities outside of the specific scene.

Cafeteria Culture: An Anthropological Approach to Lunchtime in a Central Florida Elementary School

Herrington, Emily 01 January 2017 (has links)
Public school cafeterias are used by nearly 51 million children (ages 4-17) in the United States every day. With over 40% of the approximately 73 million children (ages 0-17) participating in the National School Lunch Program (NSLP), public school lunches carry resounding nutritional, social, and educational significance for their consumers. This fact, coupled with frequent media attention to school lunch food, notwithstanding, a notable lack of social scientific engagement with both students' perspectives and NSLP operators persists. Divided into two studies, this research utilizes ethnographic methods to explore students' lunchtime experiences within a Central Florida public elementary school cafeteria. Both works are grounded in information collected from 22 semi-structured and unstructured interviews with students, parents, cafeteria workers, school faculty, and a county official while also participating in a one-month lunchtime observation period in Spring 2017. The first study utilizes ethnographic methods to investigate students' food selection, social practices, and mealtime behaviors within the cafeteria. In this work, I argue that student's preferences are most often informed by taste and familiarity, though both age and personal belief systems strongly outline students' experiences. In the second study, I focus on the top-down priorities of nutrition, food production, and student feedback that guide how institutions construct lunch menus for elementary students. Specifically, I investigate what role public institutions play in forming elementary school students' understandings of food and expectations for mealtimes. Synthesizing findings from both studies, I assess how social, economic, and industry pressures are tangible within local cafeteria and governmental contexts. This research contributes to academic scholarship and public policy regarding childhood nutrition in institutionalized settings and advocates for the inclusion of elementary-aged children as important social actors in their call for increased and dietarily-inclusive food options.

An Investigation of the Biomechanical Implications of Lower Limb Fractures and Leg Length Disparity

Mills, Elizabeth 01 January 2016 (has links)
One of the primary goals of biological anthropology is to develop an accurate understanding of human anatomy, health, disease, and injury in both modern and archaeological populations. Paleopathological analyses are a fruitful means of identifying disease and injury in skeletal assemblages, but the individual long-term biomechanical effects associated with pathological conditions have not yet been adequately explored in the literature. Leg fractures are a common pathological condition in both modern and archaeological populations, the effects of which may alter the biomechanics of gait. A growing body of clinical literature demonstrates that abnormal ambulatory function may have far-reaching effects in the rest of the body. To assess the long-term consequences of pathological conditions of the lower extremities, the relationship between lower limb long bone fracture occurrence, incidence of leg length disparity (LLD), and temporomandibular dysfunction (TMD) was analyzed. A total of 56 adult individuals (29 fractured, 27 unfractured) from the Hamann-Todd Osteological Collection (HTOC) at the Cleveland Museum of Natural History (curated between 1912 and 1938) were examined in this study. In total, the sample consisted of 37 males and 19 females (ages 25-76) of either black or white ancestry. LLD was assessed by taking standardized measurements of the lower limb long bones. TMD was analyzed by scoring the presence and severity of osteoarthritis of the temporomandibular joint (TMJ OA), dental attrition, and antemortem tooth loss. Kendall's Tau correlation statistics were used to assess morphological integration between all unique pairwise combinations of lower limb and jaw measurements among unfractured and fractured groups. Results indicate that several measures of LLD and jaw dysfunction are correlated differently in the unfractured and fractured groups. Comparisons of the All Unfractured and All Fractured groups most often showed higher absolute correlation values in unfractured individuals. Samples were also subdivided and compared based on known sex. Significant differences in patterns of morphological integration were observed between male and female sub-samples. Significant correlation values were almost always higher in the unfractured sample than in the fractured sample. Females, however, demonstrated both significant increases and significant decreases in absolute correlation values when comparing fractured and unfractured samples. Thus, patterns of significant differences in morphological integration between the lower limbs and jaw differ for males and females, with fairly consistent decreases in integration strength in the former and a mixed pattern of integration strength increases and decreases in the latter, when a leg fracture is involved. It is argued that these differences are explained by fundamental sexually dimorphic morphological and kinematic differences between males and females, such that fractures resulting in LLD affect the two sexes differently. Gendered lifetime social experiences and activity patterns may also explain the different male and female patterns identified in the analysis. These insights are applied to larger anthropological questions of social identity and the long-term injury experience.

Reflectance Transformation Imaging: Documenting Graffiti in the Maya Lowlands

Gill, Rachel 01 January 2018 (has links)
In the late 19th century, explorers identified graffiti etched in stucco walls of residences, palaces, and temples in the Maya Lowlands. By the mid-20th century, scholars acknowledged that the ancient Maya produced these incised images. Today, archaeologists struggle with documenting these instances of graffiti with precision and accuracy, often relying solely on to-scale line drawings to best represent the graffitied image they see before them. These images can be complex, multilayered, and difficult to see so identifying the sequence of creation of the incisions can be challenging. Reflectance Transformation Imaging (RTI) is a method that uses a moving light source and photography in order to visualize, interact with, and analyze a three-dimensional object in a two-dimensional image. Performed on a series of 20 unique graffiti from the Maya archaeological site of Holtun, RTI showed promise as a viable technique for documenting and preserving graffiti as cultural heritage and for providing new information about an enigmatic aspect of Maya archaeology. Additionally, RTI is compared to other common methods used to document incised graffiti in the Maya lowland area including to-scale line drawing, tracing, photogrammetry, and scanning to show the new and unique information and data that can be gathered from this method. Finally, RTI is a low-cost, low-maintenance alternative data-gathering method for highly remote archaeological projects where other technology is difficult to obtain and use in the field setting.

Reproductive Rights and Justice Advocacy in Central Florida: Who is Represented?

Hager, Mary 01 January 2018 (has links)
This thesis examines the racial understanding and social relationships of Planned Parenthood of Southwest and Central Florida staff and volunteers. As well, this research explores how Planned Parenthood supporters organize and promote diverse advocacy work to promote reproductive justice in social media and volunteer education. Planned Parenthood has been at the forefront of reproductive rights campaigns for over a century, and their work has often tied into contemporary feminist and political issues. Of note, feminists of color have called for a shift from advocacy for "reproductive choice" to "reproductive justice" as a way to identify the needs and predicaments of a wider range of women and to promote advocacy that is more representative of the population it aims to serve. Yet, how key non-governmental organizations such as Planned Parenthood engage with intersectional issues of ethnicity, race, sex, gender, and socioeconomic class in their advocacy work has been understudied. Using ethnographic methods of participant observation and semi-structured interviews, this research examines how volunteers and staff apply their understandings of racial disparities and inclusive advocacy efforts to better aid Central Florida's marginalized communities and communities of color. This project contributes to the greater call for policy and organizational analysis through applied anthropology and feminist studies in the United States and addresses how organizations balance the desires of their funders against the diverse needs of their patients.
