Duignan (2015) A Tale of Two Isotopes: Exploring Human Movement through Strontium Isotope Analysis in Two Medieval Danish.

During the Medieval period of Denmark, economic and trade relations grew inter-regionally, with culture, ideas, and products being transferred on a more regular basis through the 11th to 13th centuries. Beginning around 1050 AD and lasting until AD 1536, the country faced drastic climatic changes, shifting economic and agricultural practices, and disease outbreaks (most notably the bubonic plague). The current study seeks to investigate mobility during this period from two medieval cemeteries around Horsens, Denmark: the rural site of Sejet and the urban site of Ole Wormsgade, both used throughout the 12th to 16th centuries. A previous isotopic analysis using oxygen indicated that some movement was seen at these sites, with three individuals identified as potential migrants from other Scandinavian regions. This study compares the existing oxygen isotopic data with variations in 87Sr/86Sr ratios from these samples. Such ratios represent local bedrock baselines of strontium, which are slightly different between eastern and western Denmark. ICP-MS was used to measure 87Sr/86Sr ratios, and results are interpreted in the context of climatic changes and shifting socioeconomic practices. The results suggest that longer-distance movements into Denmark were seen during the Early Medieval Period. The potential migrant identified in this research points to movement towards the rural population at Sejet, and could possibly connect this migration with marriage rules influencing immigration at the time. This research demonstrates that movement during the medieval period of Denmark was a complex, dynamic, and multilinear process during a time of increasing urbanization..

Scott (2015) Putting Stress to the Test: a Critical Evaluation of the Biological Response and Physical Manifestation of Stress in the Human Skeleton

Using traditional osteological methods of stress analysis, specifically skeletal lesions and growth and development patterns, this research focuses on the timing and manifestation of stress in the hard tissues of the body and the interaction between these various indicators of poor health. The Danish Black Friars cemetery population spanning the medieval and post-medieval periods (13th-17th centuries) is used for this research to explore changing health trends during a period of socioeconomic disruption and expanding urban dwelling. The results of this study show a distinct trend between the late and early post-medieval periods where stress was elevated after the Reformation (AD 1536). Additionally, females generally show higher levels of stress than males. The poorer health experienced in the post-medieval period was likely influenced by the changing living conditions of the late 16th century where urban dwelling increased in Denmark introducing new pathogens, poorer living conditions and new environmental and working stressors, all contributing to poorer health. While the overall level of stress appears to increase into the post-medieval period, the average age-at-death is higher after the Reformation suggesting that while these individuals may have been exposed to more prolonged periods of stress, they were able to adapt and survive in spite of these hardships. This research also examines the ability to analyse stress through the extraction of ancient proteins from bone. Using MircoBCA and enzyme-linked immunoassay (ELISA) analysis, it is shown that protein preservation is good in the Black Friars population and the level of protein reflects the expected fluctuations associated with the demography of the population (i.e. age, sex) and not necessarily the influence of stressors. Overall this study provides a comprehensive examination of stress from its initial biological signal through to skeletal disruption in a climate of expanding urban development and changing socioeconomics in Denmark.

Richer  (2015) Getting into Shape: A Comparison of Three Methods used to Characterize Personal Uniqueness of the Frontal Sinuses using Computed Tomography (CT) Data.

Identification of unknown individuals is important in forensic cases to notify next of kin and to execute legal matters. Several areas in the skeleton have been proposed to aid in identification, including the frontal sinuses. The frontal sinuses have long been considered unique to each individual because of the high degree of observed morphological variation. Due to their location inside the skull, between the inner and outer tables of the frontal bone (Nambiar et al., 1999), visualisation of the frontal sinuses is achieved through radiographic imaging, typically X-Ray or computed tomography (CT).

Visual comparison and superimposition of an antemortem image over a postmortem image to identify a match is the most basic method for identifying if two frontal sinuses come from the same individual. This simple approach has given way to several methods that attempt to quantify observed morphological variation in the frontal sinuses. These methods can broadly be grouped into three categories: measurement, coding and outline methods. Recently, owing to the Daubert ruling, an increased emphasis has been placed on quantification and testing to develop accurate and replicable methods within forensic anthropology. In line with this ruling, it is crucial to test and validate all personal identification methods on independent samples.

This dissertation compares three methods for quantifying the personal uniqueness present in the frontal sinuses on an independent sample. The three methods tested here are a measurement method (Ribeiro, 2000), a coding method (Reichs and Dorion, 1992) and an outline method (Cox et al., 2009). The sample used in this study is a postmortem CT collection of 130 individuals from the University of Copenhagen. The protocols are described, including the adaptations made to the Ribeiro (2000) and Cox et al. (2009) methods which were originally designed to be used with X-ray image data rather than CT data. All methods were repeated using iii all individuals to identify intraobserver error. The three methodologies are evaluated and compared for their abilities to characterize individuality and produce unique matches in this sample. The results show that the weakest method is the coding system, while the strongest are the outline and measurement techniques. The aspects of frontal sinus morphology that made matching difficult will be discussed and recommendations for forensic anthropologists to increase standardization are made. Future directions, including the potential application of three dimensional renderings of the frontal sinuses for morphological comparison, are considered.

Gamble (2014) A Bioarchaeological Approach to Stress and Health in Medieval Denmark: Dental Enamel Defects and Adult Health in Two Medieval Danish Populations.

This research engages in a bioarchaeological analysis of two medieval Danish sites using combined microscopic and macroscopic methods in order to investigate three primary objectives. The first was to consider the relationship between childhood stress and adult health through the joint consideration of microscopic enamel defects and adult health indicators. Given the context of these populations over a period of history characterized by changing climate and socioeconomic conditions, punctuated by famine and plague, this research also sought to examine temporal patterns in health and stress through the osteological evidence. Finally, with increased urbanization over the course of the period (particularly the early medieval period), the final objective was to consider health patterns between rural and urban populations. The results showed that the number of stress events did have an impact on later life mortality, and that there was differential expression of this relationship between males and females and between surface and internal enamel defects. The temporal analysis showed a statistically significant decrease in stature after 1350 A.D. as well as a decline in leprosy and tuberculosis while treponemal infection became more common. The inter-site comparison showed higher rates of treponema and leprosy at the rural site and slightly higher rates of tuberculosis at the urban site, along with a significantly lower mean age at death for the urban sample. This likely reflects the complex nature of the rural and urban interaction during this period. This research points to the complex relationship between stress and health and outlines the importance of developing more comprehensive etiological models and operational definitions for identifying stress indicators in dental enamel.

Klales (2014) Computed Tomography Analysis and Reconstruction of Ancient Egyptians Originating from the Akhmim Region of Egypt: A Biocultural Perspective.

Despite popular and scientific interest in mummies, very few studies of ancient Egyptian mummy collections, especially from the same area, have been conducted. As such, this research is the first comprehensive analysis of mummies from Akhmim, Egypt and is one of only a few studies that investigate a large mummy collection from both a biological and cultural point of view. A group of 25 mummies from the Akhmim Mummy Studies Consortium database was evaluated using computed tomography. Using computed tomography and the associated imaging software, two dimensional (2D) x-ray scan images were analyzed, then processed and edited to generate three dimensional (3D) models of each mummy. Both the 2D and 3D images of each mummy were used to collect both biological information and cultural data in a nondestructive manner. Results from this study indicated that the population of Akhmim was very diverse. Furthermore, this research both supports and challenges conventional wisdom on how ancient Egyptians were mummifying their dead.

Gough (2013) Isotopes and Teeth: Human Movement in two Medieval Danish Cemetery Populations

The mobility patterns of two medieval Danish populations were investigated using oxygen isotopic analysis. Oxygen isotopic data were collected from the dental enamel of 26 individuals, 13 from the urban cemetery, Ole Worms Gade, and 13 from rural Sejet, both located in Central Denmark. Phosphate was chemically isolated as an oxygen analyte and analyzed using Thermal Combustion Elemental – Mass Spectrometry (TC/EA-MS) in order to minimize the effects of diagenesis on the oxygen isotopic composition of enamel. Diagenesis of the dental tissues was also investigated using spectroscopic and microscopic techniques. Secondary Ion Mass Spectrometry (SIMS) was explored as an alternate method of obtaining isotope data for these materials. Isotope data revealed three possible migrants. Results are interpreted in the context of the shifting socioeconomic climate in medieval Europe.

Sitchon (2013) Renewing Relationships at the Centre: Generating a Postcolonial Understanding of Asiniskow Ithinewak Heritage.

For the Asiniskow Ithiniwak (Rocky Cree), the Missinipi (Churchill River) holds many traditional resource areas and cultural landscapes with oral histories that transfer knowledge through the generations (Linklater 1994; Castel and Westfall 2001; Brightman 1993). In recent decades, hydroelectric development in north central Manitoba has impacted Cree livelihood by altering resource use, limiting access to significant cultural landscapes and accelerating the erosion of campsites and ancestral burials into the water. Even with existing provincial heritage legislation, some of these heritage resources remain threatened by land-based developments because of the limitations related to their identification, documentation and presentation in the cultural resource management field.  The tendency to focus on physical manifestations of heritage such as archaeological sites, heritage objects and built heritage overlooks other resources of heritage such as places known in the local language. I argue that these biases result from cultural divergences that exist in the understanding and definitions of heritage, particularly Indigenous heritage.

 

In this dissertation, I articulate how underlying theoretical assumptions of reality influences our understandings of heritage. I present a postcolonial understanding of heritage as interpreted from the perspective of the Asiniskow Ithiniwak using an Indigenous research paradigm, methodologies and the nīhithow language, in conjunction with knowledge based on Western intellectual traditions. The use of a bicultural research model led to new ways in identifying heritage resources important to the Asiniskow Ithiniwak and meaningful interpretations of archaeological materials based on legal traditions. Further, this case study demonstrates that there is no singular or universal definition of heritage for Indigenous peoples.

 

For successful heritage resources protection, I illustrate that understandings of heritage need to be contextualized locally through a community’s language, culture, customary laws and local landscape. This view, promoted by UNESCO, emphasizes that the values and practices of local communities, together with traditional management systems, must be fully understood, respected, encouraged and accommodated in management plans if their heritage resources are to be sustained in the future (Logan 2008; UNESCO 2004). This outcome demonstrates the need to re-examine the practices, policies, legislation and procedures concerned with Indigenous knowledge in cultural and natural resources management in Canada.

Campbell (2013) A Palaeopathological and Immunogenetic Assessment of Archaeological Canadian Inuit Populations.

For centuries there has been a disparity in the health of Canadian Aboriginal populations and the colonizers who came to inhabit their territories. In contemporary times, this disparity is translated into a number of growing health concerns that appear at higher rates in circumpolar populations than in many other Canadian communities. Tuberculosis rates in Arctic and circumpolar communities, particularly those with a high Inuit demographic, remain more than 20 times higher than in any other population demographic. Understanding the factors that contribute to the continued prevalence and high incidence of TB in the Arctic compared to the remainder of Canadian populations demonstrate requires a longitudinal analysis of a number of factors related to overall health.

This dissertation explores this disparity through the examination of the immunogenetics and palaeopathology of an archaeological Inuit population. This archaeological cohort was assessed using palaeopathological techniques of to establish the disease burden experienced by the Inuit in the precontact and early contact period. The palaeopathologicual inventory also established individuals with possible TB pathologies as candidates for further molecular analysis. Molecular analyses focused on the establishment of Inuit ancestry and the examination of the presence of four polymorphic sites in the promoter regions of IL6, IL10, TNFα and IFNγ. Polymorphisms for the Th2 cytokines IL6 and IL10 are associated with the down regulation of Th1 cytokines activated to combat TB infection, while the Th1 cytokines TNFα and IFNγ are essential for the effective immune response against TB infection. These analyses resulted in the establishment of genotypes and phenotypes detected utilising a novel molecular method and protocols developed specifically for this research.

Osteological observations indicated an increase in risk of disease in early contact populations, particularly those associated with infectious disease or the coinfection of multiple conditions compared to the precontact cohort. In contrast premortem tooth loss decreased with contact, and degenerative pathologies maintained a relatively balanced presence. TB pathologies were observed in both precontact and contact groups, with an increased level of pathologies observed in contact individuals. Molecular results suggest immunogenetic profiles similar to First Nations groups, with only a single cytokine SNP exhibiting a unique phenotype in comparison. Immunogenetic profiles suggest Inuit have maintained a Th2 immune response for many generations, and this remains unchanged with contact.

Maltais Lapointe (2013) Validation of the New Interpretation of Gerasimov’s Nasal Projection Method for Forensic Facial Approximation.

Approximating the facial features for forensic facial approximation is challenging, especially the nose. Numerous methods have been published to position the tip of the nose in profile with variable results. Gerasimov’s two-tangent method is the most commonly used. However, a recent article published by Ullrich and Stephan (2011) states that the method was not properly performed and provides new guidelines. This research used a sample of CT scans from a Denmark population (N=66) to determined which of Gerasimov’s literal translation or Ullrich and Stephan’s (2011) new version of the two tangent method is the most accurate. A combination of the two methods was also evaluated to determine the effect of each tangent independently, and the effect of intraobserver error. It was determine that the new guidelines result in smaller mean difference but no method can accurately position the tip of the nose due to the lack of experience from the practitioner. remains.

Lidstone (2011) Analysis of Sexual Dimorphism in Human Eye Orbits using Computed Tomography

A plethora of anthropological studies have been undertaken on the skull, including many analyses of sexual dimorphism.  Sexual dimorphism reflected in the eye orbits has not always demonstrated consistent or reliable results.  However, recent studies (Pretorius, Steyn, & Scholtz, 2006; Ji et al., 2010) suggest some positive results utilizing geometric morphometrics to predict sex.  Utilizing 97 post-mortem CT (computed tomography) scans, established morphological and metric techniques for sex determination were assessed from 3D rendered models of the crania.  In addition, landmark data were collected on the orbital margin to evaluate the accuracy of sex determination using geometric morphometric techniques.  Traditional methods demonstrated poor levels of accuracy for prediction of sex, however, utilizing generalised procrustes analysis and discriminant function analysis on 3D landmark data resulted in 94.95% overall accuracy.  Application of recent methodological advances, including geometric morphometrics, should continue to be developed as it increases the ability to assess sexual dimorphism which will allow for greater identification of unknown remains.

 

Symchych (2010) Craniofacial Growth and Development in the Roebuck Sample

The purpose of this research is to better understand the health of the Roebuck  Iroquois population through the study of the growth of its children.  Four avenues of osteological analysis are employed to investigate this topic:  the comparison of craniofacial measurements to dental age, comparison of craniofacial measurements with one another, assessment of fluctuating asymmetry, and comparisons to other populations.  The Roebuck subadults demonstrated a pattern of craniofacial growth consistent with the pattern for a normal, healthy child.  Growth spurts in the craniofacial complex were more difficult to observe and interpret than spurs in the long bones.  Fluctuating asymmetry was not found in any of the bilateral measurements, indicating that any stress experienced by the Roebuck subadults during development was not great enough to have a detectable impact on cranial symmetry.  Roebuck appeared to be similar in size and growth to two other populations with similar subsistence strategies and diets.

Lefever (2010) Laser Ablation of Modern Human Cementum: The Examination of Trace Element Profiles.

This study used LA-ICP-MS on a documented sample of modern teeth to sample from a continuous line across the cementum increments thus creating a temporal line graph of the elemental composition against distance. The knowledge of cementum was extended through (1) a more complete elemental composition analysis and (2) the relation of element distribution to the ultrastructure structure throughout the life of a tooth.  This study was exploratory and demonstrated that lead, zinc, mercury, and barium follow the same general line of changes, and most likely represent changes in health and exposure to these metals in the general environment.  Copper, manganese and vanadium varied very little.  Technological limitations prevented the examination of element levels in any one annulation.

Blackburn (2010) Bilateral Asymmetry of the Humerus throughout Growth and Development.

This project investigates the development of asymmetry throughout growth by using bilateral asymmetry of the humerus as a proxy for handedness. A large skeletal sample of non-adults combined with a smaller sample of adults, primarily from British archaeological sites, was examined in order to detect when handedness appears in the human skeleton. Traditional measurements were combined with 3D data in order to provide a comprehensive picture of bilateral asymmetry.  Results of this work indicate a striking trend from left to right-handedness during growth and development, with infants and toddlers exhibiting left-sided asymmetry and older children and adolescents demonstrating right-sidedness. Interestingly, this trend is consistent with what has been observed behaviourally in children, suggesting that biomechanical forces strongly influence bilateral asymmetry in the upper limb bones. In addition to examining handedness throughout growth, this research also explores bilateral asymmetry more generally as it is impossible to fully understand handedness without observing how asymmetry varies according to different factors. Although this work supports the hypothesis that all human populations are right-handed, there are subtle differences between groups. Results indicate that British populations became more asymmetrical over time, with this becoming most pronounced during the Industrial Revolution. Differences in degree of asymmetry between males and females was also noted, suggesting differences in activity between the two groups, as well as supporting the notion that the male and female skeleton differ in how they respond to biomechanical forces. Overall, this work provides a comprehensive analysis and discussion of how handedness presents in the human skeleton.

Moore (2009) Dental Age Estimates of Individuals Buried at the Apollonia Pontica Site.

One primary challenge when attempting to ascertain adult age-at-death of unknown archaeological skeletal remains are the issues of subjective age estimation methods/techniques, age ranges, bias caused by the burial environment, and the use of multiple skeletal elements. Teeth, as opposed to bones, have several attributes that obviate these problems. This research uses a canine dental sample from the Apollonia Pontica site and addresses these issues using robust dental age indicators (transparency and pulp reduction), comparing the age estimates from two methods (digital and manual), applying multiple quantification techniques, and comparing these results to associated skeletal morphological age markers. The digital method of the transparency techniques corresponded closest to the skeletal morphological age estimates and was applicable on the largest sample portion. The dental age estimates have been established for the Apollonia Pontica sample and contributed by producing a single age estimate using objective techniques.

Carter (2009) Monkey Hear: A Morphometric Analysis of the Primate Auditory Ossicles.

Hearing plays a vital role in the life of primates and an understanding of the anatomy of the auditory ossicles is necessary for analyses of hearing sensitivity. Morphometric studies conducted on the auditory ossicles of primates are rare and those few have tended towards simple magnitude and anatomical length measures.  To address this issue, a landmark analysis based on Schmidt et al. (2009) was conducted on ultra-high resolution computer tomography (UhrCT) scans of twenty-six primate auditory ossicle chains. The resulting data were subjected to Euclidean distance matrix analyses (EDMA) in order to discuss differences between morphology between the species represented. A percussive forager, Daubentonia, was included to investigate whether its unique ‘hunting’ style affected its ossicular morphology. Two representatives of the non-primate family Cynocephalidae were also included as an outgroup to the primates in order to provide a non-primate comparison for the morphometric and taxonomic analyses.

The results of these investigations demonstrate that the greatest variable in ossicle morphology is size. In the shape analyses, the greatest differences occurred between the landmarks measuring the maximum length of the malleus, the maximum length of the incus and the maximum width of the ossicular chain bodies. The haplorrhine–strepsirrhine split is well reflected in ossicle morphology. Clustering into biological families was strong and the scaled data reflected the accepted taxonomy, although the hierarchy within families tended to be out of order compared to the cladogram. The results of the cluster analyses indicate that although diet and activity patterns may be relevant when discussing the morphology of a specific species, the grouping is not strong enough to suggest that these patterns are an important factor in adaptation. The auditory ossicles of the percussive forager are unusual in form and are the largest of all the species represented. Daubentonia’s unique method of ‘hunting’ would seem a likely cause of the outstanding shape differences, although this remains impossible to prove without further study. The Cynocephalidae have a unique ossicular morphology within the context of this study. Morphological evaluation of the Cynocephalidae auditory ossicles demonstrates a lack of concordance with the majority of phylogenetic hypotheses and highlights the issues with using cluster analyses to make phylogenetic-morphological assumptions. The EDMA method provided unanticipated information regarding the articulation angles of the ossicular chains, particularly that of V.v. variegata. The results provided by this study present opportunities for future research and suggest many new questions on the morphology of primate auditory ossicles.

Morgan (2009) Sex Determination Using the Petrous Portion of the Temporal Bone:  A Validation Study of Three Cranial Techniques Using Computed Tomography (CT) Scans.

This study reports on the validation of three previously published methods of sex determination for the petrous portion of the temporal bone using computed tomography (CT) scans.  The objectives of this study were to evaluate the lateral angle (Akansel et al., 2008; Graw et al., 2005; Norén et al., 2005), diameter (Lynnerup et al., 2006), and length methods (Papangelou 1975) for the internal acoustic canal in accurately determining the sex of human skeletal remains using image-based measurements.  The mean differences for all of the measurements did not reach statistical significance (p < 0.05) and the sex differences reported for the previous cadaveric studies (Akansel et al., 2008; Graw et al., 2005; Lynnerup et al., 2006; Norén et al., 2005; Papangelou 1975)  were not substantiated here; however,  the consistency in the means and ranges of measurements between the current study and the previous research suggests that computerized tomography (CT) is capable of reproducing direct anatomic measurements of the skull.

ten Bruggencate (2008) Fidler Mounds: Ancient Mortuary Practice and Manitoba’s Dynamic Cultural Landscape

Secondary ion mass spectrometry (SIMS) was used to obtain stable oxygen isotope data from the dental tissues of 12 individuals once interred at Fidler Mounds (EaLf-3), a cemetery mound site located in south-central Manitoba, 19 kilometers north of Winnipeg.  Fidler Mounds was originally constructed c.1800BP and was utilized as a burial ground by precontact peoples in Manitoba for approximately 1000 years thereafter.   The use of SIMS allowed the researcher to obtain several in situ δ18O values from each individual’s intact cementum, dentin and enamel.  These values show that mobility patterns during Manitoba’s middle and late Woodland period were extremely complex and varied.   Additionally, intra-tissue δ18O variability recorded through SIMS analysis indicates that traditional mass spectrometry may not be appropriate for assessing migration patterns within highly mobile populations.

Campbell (2007) Biomechanical Modifications of the Skeletal System Influenced by Major Economic Shifts in Agricultural Production

 

This research focuses on the influences of shifts in agricultural practices on the patterns of daily repetitive activities and their associated reflections on the skeletal system.  Denmark in particular experienced broad changes in agricultural production after the Black Death with a shift in the primary form of agricultural production from grain production to livestock rearing.  These changes in lifestyle activities are hypothesized as being reflected in modification of the musculoskeletal system.  Using metric analysis and musculoskeletal stress markers (MSM’s) individuals are assessed for biomechanical modification to ascertain if the changes in agricultural production can be traced through the skeletal system by way of MSM’s.  Results suggest a decrease in robusticity and overall musculature from the grain producers to those who rear livestock, as well as more apparent trends such as differences in male and female musculature.  Comparisons between the high and low status individuals illustrate that there is a distinct division of labour between the two, as well as within the groups.

Holland (2007) What about the Children? Incorporating Osteological, Archaeological and Ethnographic Information to Understand Sadlermiut Childhood in the Past.

Skeletal remains have long been used by physical anthropologists in order to understand the health and lives of past peoples. The purpose of this research is to better understand the lives of the Sadlermiut children from Native Point Southampton Island, Nunavut. To do so, a three-fold methodology integrating archaeological and ethnographic evidence of children and childhood with an osteological analysis of growth and development is utilized.  This is the first study to concentrate on the skeletal remains of those less than 18 years of age from the Sadlermiut archaeological sample. This research suggests a high prevalence of infant mortality among the Sadlermiut, the largest proportion of which were female. The growth of the Sadlermiut is comparable to that of the Eskimo and Aleut from Alaska, yet less than that of modern children of European descent, and other Aboriginal archaeological populations from North America.

Allard (2006) The Role of 3D Printing in Biological Anthropology.

The following work explores the role of 3D printing in biological anthropology. A case study approach is used to provide an understanding of two different applications for 3D printing in biological anthropology and to identify a potential methodology for creating 3D models. Case study one looks at the application of 3D printing to reconstruction projects using a flowerpot to test the reconstruction methodology. The second case study uses both laser surface and CT scanning to create a replica of a human skeleton. The two methods of data acquisition are evaluated for advantages and limitations in creating the virtual model. This work shows that there is a role for 3D printing in biological anthropology, but that data acquisition and processing issues are the most significant limiting factor in producing skeletal replicas.

Gill-Robinson (2005) The Iron Age Bog Bodies of the Archaeologisches Landesmuseum, Schloss Gottorf, Schleswig, Germany.

The purpose of this research was to provide a complete anthropological assessment of the remains of seven humans from peat in northern Germany. The group of bog bodies at the Archaeologisches Landesmuseum was a unique collection since it included a well-preserved adult male (Rendswühren); two of the "flat" bodies, with completely demineralized bones (Damendorf and Windeby 11); a potential adolescent female (Windeby 1) and two heads with distinctive hair knots (Osterby and Dätgen). A single bog skeleton, from alkaline peat, Kühsen, was also examined. All of the bodies dated to the Scandinavian Iron Age, approximately 500 B.C. to A.D. 800, with the exception of the bog skeleton, the date of which was unknown. The remains displayed varying levels of preservation but in all cases, except the skull and mandible, extensive soft tissue remained on the bodies. With the exception of the Windeby 1 body, little previous research had been undertaken with the bodies in this collection. Each body was completely reassessed and reinterpreted based on evidence compiled from multiple sources including archival material; gross anatomical analysis; digital radiography-, Multi-slice computed tomography (MSCT); detailed image analysis with both virtual and physical three- dimensional reconstructions and trace element and stable isotope analyses. One body was sampled for ancient DNA analysis. Several of the techniques employed were used with bog bodies for the first time. Data were compared with Iron Age skeletal remains from Denmark and Iron Age cremation burials from Schleswig-Holstein. From this research, interpretations regarding methodological issues of preservation and analysis, and how these individuals might have fit within the archaeological and cultural context of the Iron Age in northern Germany were made. The data obtained from these analyses contributed substantially to the interpretation of these seven individuals.

Green (2005) The Epidemiology of Diabetes in Manitoba: An Exploration Through Time and Space.

Diabetes mellitus (DM) is becoming epidemic world wide, with the number of cases projected to increase from 171 million cases in the year 2000 to 366 million cases in the year 2030.  The number of cases of DM in Manitoba is also rapidly increasing.  In 1998, it was estimated that there were 54,926 adults living with diagnosed DM in Manitoba, a significant increase from 30,104 cases in 1986.  The purpose of this study was to describe the temporal and geographic variability of DM in the province of Manitoba and to assess the degree to which this variability is associated with underlying population characteristics.  This was accomplished in four separate studies. The first study focused on describing and modeling the spatial distribution of DM prevalence in the City of Winnipeg, Manitoba in 1998.   The second study compared the demographic, temporal and geographic patterns of DM incidence and prevalence in the Manitoba First Nation population to the non-First Nation population from 1989 to 1998.  The third study used a number of diverse spatial techniques to visualize, explore and model the incidence of DM in the province of Manitoba between 1989 and 1998. The fourth study used a component cohort projection model to back-cast and forecast the prevalence of DM in Manitoba from 1950 to 2050.  All analyses were based on DM incidence and prevalence data derived from the Manitoba diabetes database.  The results of these four studies suggest that the number of DM cases will continue to rapidly increase into the foreseeable future in Manitoba.  They also suggest that despite an observed gradient in DM risk by age, socio-economic and First Nation status, all population groups are at significant risk for developing the disease.  It is concluded that prevention programs focusing only on groups at highest risk for developing DM will have little chance of success and that population based prevention approaches which tackle the fabric of everyday life will be required to stem the epidemic.  It is also concluded that population based prevention efforts will need to be informed by further research utilizing diverse historical, anthropological and geographical research methods which can identify the range of forces affecting DM risk, and the types and scales of interventions which may be required simultaneously at individual, local, regional, national, and even international levels to deal effectively with the DM epidemic.

Larcombe (2005) Native North American Resistance and Susceptibility to Infectious Diseases: An Anthropological Approach.

Infectious disease agents have a profound effect on human biological and cultural evolution. Understanding the processes involved in the biological response to pathogens and the genetic factors that contribute to disease resistance and susceptibility, are integral to understanding the adaptation to diseases by New World Aboriginal populations. Complex historic and evolutionary events led to the immunogenetic profile of the North American indigenous population, and it is only within an evolutionary context that we can make sense of the differential rates of morbidity and mortality that occurred and continue to occur between ethnic groups. This research compared the frequency of single nucleotide polymorphisms (SNPs) in the promoter region of cytokine proteins (key regulators of the immune system) in a contemporary Aboriginal and Caucasian study population and established that a significant difference exists. Results suggest that the contemporary Aboriginal study population differs from Caucasians in their ability to express cytokines that are effective against infectious pathogens that require a cell-mediated immune response. The analysis of the cytokine SNP frequencies maintained by the contemporary Aboriginal population within a functional, adaptive context suggests substantially more complex pattern of evolution.

To explore the observed immunogenetic profile of Aboriginals within an evolutionary framework, a novel technique for detecting SNPs in the cytokine promoter regions of ancient human remains from Manitoba was developed. The development of new molecular methods for detecting SNPs which have been shown to be linked to disease resistance and susceptibility, is the first step towards understanding the role of genetic factors in the human immune response to infectious disease. This will contribute to understanding why certain infectious diseases continue to profoundly impact contemporary North American Aboriginal populations.

Hewitt (2004) Health of Mortality at Fidler Mounds (EaLf-3): A Bioarchaeological Assessment.

The Fidler Mounds skeletal sample was recovered in a salvage excavation during 1963 and has been curated in the Department of Anthropology at the University of Manitoba since then.  In an age when impending repatriation of archaeological material is simply a matter of time, it is critical that we study the human remains currently housed in universities and museums so that the information they hold is not lost.  Since the last time the Fidler Mounds human remains were examined, in the early 1970’s, technology has substantially advanced our ability to examine and interpret the health and well-being of past populations, particularly through biochemical studies.

As a means to better understanding the challenges faced by those interred at the Fidler Mounds, multiple approaches were employed in this study.  Accelerator Mass Spectrometry dating of several of the discrete burials in the sample was carried out in order to generate a range of dates during which the mound was used.  Gross osteological analysis was coupled with archaeological and ethnographic information for the region to paint a picture of who the builders (or users) of the mounds may have been, and how they fit into the currently understood culture history of the northeastern Great Plains.  Recent developments in the geological sciences allowed for a test of the applicability of Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry to the study of changes in trace element concentrations during childhood.  While the interpretation of these data is still a challenge, the results are very encouraging.

Torwalt (2003) A Replicability Study of Radiographic Techniques for Aging and Sexing the Human Skeleton.

The purpose of this research is to evaluate current methods in adult human thoracic (chest plate) aging and sexing techniques as done through radiographic analysis. Sex differences as well as age related changes in the skeleton can be found within the human thoracic area. These may include morphological changes in the costal cartilage of the 1st through 7th ribs, sternal end of the clavicle, costo-manubrial border, as well as sternal length, and fusion rates. The thoracic region is extremely important in biological and forensic anthropological studies as it is active between the adolescent growth and adult maturation and degenerative periods, allowing age estimates to be generated with relevance to both immature and adult skeletal remains. It also presents an opportunity to obtain greater degrees of accuracy in the often difficult and subjective task of adult age estimation and sex determination, especially when dealing with partial remains. This research focuses on whether or not previous radiographic techniques for determinations of age and sex are useful in contemporary forensic situations in so much that these methods are replicable and accurate.

Sitchon (2003) Estimation of Age from the Pubic Symphysis: Digital Imaging versus Traditional Observation

 

A main challenge facing skeletal age determination is the inability to distinguish discernible aging features in older adults. This study addresses this issue with a threefold process involving age estimation from the pubic symphysis.

The first component consists of an evaluation of the Transition Analysis age estimation method (Boldsen and colleagues, 2002) in determining the age at death of 105 adults from the Grant collection. This aging technique applies a new statistical approach to calculate age at death from scores from the adult cranium and pelvis with a priori uniform or informative age distributions. The method predicted the ages at death of the older adults successfully with the assistance of broad age intervals to accommodate the increased variation expressed in the skeletal morphology with senescence.

The study progressed further with an examination of age at death determination from digital images of the pubic symphysis. Digital images offer the potential to develop an extensive skeletal database of an array of populations, as a means to analyze and control variations to produce precise age estimates for older adults. A comparison of 52 Suchey-Brooks scores assigned to digital images and actual bone revealed that age estimation is possible from the images but must be approached with caution. The subjective nature of scoring from digital photographs and actual bone demonstrates the limitations of the naked eye in identifying age related changes in certain skeletal features, especially where older adults are concerned.

The final component examines whether the application of image analysis techniques can identify discernible morphological changes related to increasing age from digital images of the pubic symphysis. Measures of image pixel brightness and pixel intensity data translated into line plots represent the range of elevations on a surface. Elevation data corresponded with different textures and relief exhibited in the various age-related stages of the symphyseal surface.   Further, the plots delivered insightful information into age-related changes of the pubic symphysis unrecognized by the human eye. The results suggest that image analysis should not be overlooked as a useful tool to refine age estimation methodologies.
