Estudo estimativo do sexo em crânios da região de Guarulhos-SP utilizando antropologia física e DNA / Estimative study of the sex in skulls from the region of Guarulhos-SP using physical antropology and DNA

Carvalho, Suzana Papile Maciel 17 January 2013 (has links)
A investigação do sexo é uma das análises mais importantes na identificação humana. Este trabalho teve como objetivo a determinação do sexo em crânios humanos utilizando três métodos de Antropologica Física, duas quantitativas (Forensic Data Anthropolgy Bank, FDB, 1986 e Oliveira, 1995) e uma qualitativa, (Walker, 2008), e a análise genética pela amelogenina. A amostra foi composta de 66 crânios (34 homens e 32 mulheres) do Centro de Estudo e Pesquisa em Ciências Forenses, Guarulhos, SP. As metodologias foram aplicadas por duas pesquisadoras, que desconheciam o sexo dos crânios. Para o estudo estatístico realizaram-se análise descritiva, média, desvio padrão, análise discriminante linear e logística e regressão logística. A metodologia quantivativa apresentou um acerto de 89,52%. O Método FBD teve uma acurácia de 92,31%, com a elaboração de uma fórmula utilizando as medidas Largura Bizigomática, Altura Nasal, as quais apresentaram o maior dimorfismo entre os sexos, e Altura Básio-bregma e Máximo Comprimento do Crânio. A metodologia de Oliveira et al. (1995) necessitou de ajuste para a população estudada (nova fórmula com acurácia de 76,47% em homens e 78,13% em mulheres). Para o DNA, foi possível determinar o sexo em 86,15% da amostra. Pode-se afirmar que as diferentes metodologias comportaram-se de modo semelhante e com alta acurácia para determinação do sexo. A antropologia física apresenta as vantagens de facilidade de aplicação, reprodutibilidade e baixo custo, porém, necessita de ajustes populacionais. O DNA é mais complexo, necessita de infraestrutura e insumos específicos e pode ter interferência da condição ambiental, fatores que dificultam as análises, entretanto, não precisa ser ajustado á população. / The investigation of the sex is one of the most important analyzes in the human identification. This study aimed to determine the sex in human skulls using three methodologies of Physical Anthropology, two quantitative (Forensic Data Anthropology Bank, FDB, 1986 e Oliveira, 1995) and one qualitative (Walker, 2008) and genetic analysis by amelogenin. The sample was composed by 66 skulls (34 men and 32 women) from the Center for Study and Research in Forensic Science, Guarulhos, SP. The methodologies were applied by two researchers who were unaware of the craniums sexes. For the statistical analysis, there were performed descriptive analysis, average, standard deviation, linear discriminant analysis and logistic and logistic regression. The quantitative methodology presented an accuracy of 89.52%. The FBD method had an accuracy of 92.31%, with the development of a mathematical model using the measures Bizygomatic breadth, Nasal heigh, which showed the biggest dimorphism between the sexes, and Basion-bregma height and Maximum Cranial Length. The Oliveiras et al. (1995) methodology required adjustment for the studied population (new formula with an accuracy of 76.47% in men and 78.13% in women). For the DNA, it was possible to determine the sex in 86.15% of the sample. The different methodologies behaved similarly and with high accuracy in sex determination. Physical anthropology has the advantages of being easy to use, reliability and low cost, but needs population adjustments. The DNA is more complex, requires specific reagents and structure and may have interference from environmental condition, however, does not need to be adjusted to the population.

Biological Affinities and the Construction of Cultural Identity for the Proposed Coosa Chiefdom

Harle, Michaelyn S 01 May 2010 (has links)
This study couples biological data with aspects of material culture and mortuary ritual for several sites within the proposed Coosa chiefdom described by sixteenth-century Spanish accounts to explore how cultural identities were actively constructed and maintained within the region. The primary goal is to examine regional interactions between these communities and their constructions of social identity and sociopolitical dynamics vis à vis their biological affinities. Questions regarding regional interactions between these groups have been a stimulus for archaeological debate. These interactions may have played a crucial role in the construction of separate cultural identities. What is not clear is to what extent differences in cultural identity reflect or are related to differences in biological relationships. The skeletal samples used in this study represent six Late Mississippian archaeological sites assigned to three archaeological phases: the Dallas Phase, Fains Island (40JE1), Cox (40AN19), and David Davis (40HA301) sites; the Mouse Creek Phase, Ledford Island (40BY13) site; and the Barnett Phase, King (9FL5) and Little Egypt (9MU102) sites. Twenty-seven dental and 22 cranial nonmetric traits were recorded for 923 individuals. Biological affinities were calculated using the Mahalanobis D2 statistic for the cranial and dental non-metric traits. Biological Distance measures were compared to a geographic matrix to examine isolation by distance between the sites. Further analysis was conducted by constructing an R matrix to examine levels of heterogeneity. Comparisons between biological distance and geographical distances suggest that the samples used in this analysis do not conform to the expected isolation-by-distance model. Furthermore, East Tennessee groups appear distinct from their North Georgia neighbors suggesting little biological interaction between these groups. The results of the biological distance analysis conforms to differences in material culture and mortuary ritual between these groups. The results suggests that if there was a political alliance within the region for this period it is not associated with biological relatedness nor did it act as a unifying force for individual communities’ cultural identity.

The Impact of Wildlife Conservation Nonprofits: An Examination of Environmentalism and Organizational Culture in the United States and Ecuador

Brooks Ames, Sophie 01 April 2013 (has links)
This thesis examines the social impact of wildlife conservation nonprofits (WCNs) in the United States and Ecuador. Cultural developments of environmentalism provide the social context for WCNs, informing trends in participation and conflict. WCNs rely on public support and engagement to advance their mission, which requires an image of legitimacy and healthy organizational culture. This thesis argues the relationship between WCNs and the public impacts their organizational sustainability and their success as a conservation institution.

Behavioural strategies of the ring-tailed lemur (Lemur catta) in a sub-desert spiny forest habitat at Berenty Reserve, Madagascar

Ellwanger, Nicholas 08 January 2008 (has links)
In an effort to better understand primate behavioural flexibility and responses to low-biomass habitats, behavioural patterns of ring-tailed lemurs (Lemur catta) living in a xerophytic spiny forest habitat in southern Madagascar were examined. Behavioural data were collected over two months on two separate groups living in two distinctly different habitats: a sub-desert spiny forest and a riverine gallery forest. Data on the following behavioural categories integral to primate sociality were collected: time allocation, anti-predator vigilance, predator sensitive foraging, feeding competition, and affiliative behaviour. L. catta living in the spiny forest habitat differed significantly in many behavioural patterns when compared to L. catta living in the gallery forest. I suggest that the ability to successfully alter behavioural strategies to varying ecological conditions allows ring-tailed lemurs to occupy low biomass habitats which are uninhabitable to nearly all other primate species in Madagascar. Lemur catta evolution, behavioural flexibility, and conservation will be discussed.

Bioarchaeology of violence and site abandonment at Casas Grandes, Chihuahua, Mexico

Casserino, Christopher Michael, 1967- 06 1900 (has links)
xvii, 133 p. : ill., maps. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number. / The objective of this dissertation is to address violence at the archaeological site of Casas Grandes (Paquimé) in northwest Chihuahua, Mexico. The reasons for the abandonment of Paquimé are uncertain. The prevailing theory claims this geographic area endured centuries of warfare, ritual sacrifice, and at least one massacre; this theory is supported by numerous unburied bodies recovered at the site. These assertions of violence have never been corroborated by osteological data. Data were collected from a sample of Medio period (A.D. 1200-1450) human skeletal remains recovered from the 1958-1961 excavations at Casas Grandes. These data were synthesized with accelerator mass spectrometry radiocarbon dates, fluoride ion dates, population demographics, and burial context. Frequencies of ante-, peri-, and postmortem trauma were compared to other studies from the Old and New Worlds. I argue that warfare was not endemic to this region and that a massacre did not occur. Moreover, cannibalism and probably human sacrifice were practiced. I assert that these activities may have been related to the proliferation of the Mesoamerican ballgame in the American Southwest and to Paquimé's role as the distribution center of the region's ritual and exotic goods. This dissertation underscores the importance of including skeletal analysis with other lines of archaeological inquiry when answering questions about human behavior. / Committee in charge: John Lukacs, Chairperson, Anthropology; Guy Tasa, Member, Anthropology; Frances White, Member, Anthropology; John Orbell, Outside Member, Political Science

Variation in Dental Microwear Textures and Dietary Variation in African Old World Monkeys (Cercopithecidae)

January 2015 (has links)
abstract: Dietary diversity is an important component of species’s ecology that often relates to species’s abundance and geographic distribution. Additionally, dietary diversity is involved in many hypotheses regarding the geographic distribution and evolutionary fate of fossil primates. However, in taxa such as primates with relatively generalized morphology and diets, a method for approximating dietary diversity in fossil species is lacking. One method that has shown promise in approximating dietary diversity is dental microwear analyses. Dental microwear variance has been used to infer dietary variation in fossil species, but a strong link between variation in microwear and variation in diet is lacking. This dissertation presents data testing the hypotheses that species with greater variation in dental microwear textures have greater annual, seasonal, or monthly dietary diversity. Dental microwear texture scans were collected from Phase II facets of first and second molars from 309 museum specimens of eight species of extant African Old World monkeys (Cercopithecidae; n = 9 to 74) with differing dietary diversity. Dietary diversity was calculated based on food category consumption frequency at study sites of wild populations. Variation in the individual microwear variables complexity (Asfc) and scale of maximum complexity (Smc) distinguished groups that were consistent with differences in annual dietary diversity, but other variables did not distinguish such groups. The overall variance in microwear variables for each species in this sample was also significantly correlated with the species’s annual dietary diversity. However, the overall variance in microwear variables was more strongly correlated with annual frequencies of fruit and foliage consumption. Although some variation due to seasonal and geographic differences among individuals was present, this variation was small in comparison to the variation among species. Finally, no association was found between short-term monthly dietary variation and variation in microwear textures. These results suggest that greater variation in microwear textures is correlated with greater annual dietary diversity in Cercopithecidae, but that variation may be more closely related to the frequencies of fruit and foliage in the diet. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2015

Landscape Variability in Tool-Use and Edge Damage Formation in South African Middle Stone Age Lithic Assemblages

January 2016 (has links)
abstract: This study explores how early modern humans used stone tool technology to adapt to changing climates and coastlines in the Middle Stone Age of South Africa. The MSA is associated with the earliest fossil evidence for modern humans and complex cultural behaviors during a time period of dramatic climate change. Human culture allows for the creation, use, and transmission of technological knowledge that can evolve with changing environmental conditions. Understanding the interactions between technology and the environment is essential to illuminating the role of culture during the origin of our species. This study is focused on understanding ancient tool use from the study of lithic edge damage patterns at archaeological assemblages in southern Africa by using image-based quantitative methods for analyzing stone tools. An extensive experimental program using replicated stone tools provides the comparative linkages between the archaeological artifacts and the tasks for which they were used. MSA foragers structured their tool use and discard behaviors on the landscape in several ways – by using and discarding hunting tools more frequently in the field rather than in caves/rockshelters, but similarly in coastal and interior contexts. This study provides evidence that during a significant microlithic technological shift seen in southern Africa at ~75,000 years ago, new technologies were developed alongside rather than replacing existing technologies. These results are compared with aspects of the European archaeological record at this time to identify features of early human technological behavior that may be unique to the evolutionary history of our species. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2016

De Chinchorro a Chiribaya: los ancestros de los mallquis Chachapoya-Inca

Guillén, Sonia E. 10 April 2018 (has links)
From Chinchorro to Chiribaya: The Ancestors of the Chachapoya-Inca MallquisIn 1977 agricultural workers, turned into looters, found an intact funerary site in the cloud forest in northeastern Peru. A prompt archaeological rescue project permitted the recovery of an important collection of mummies and artifacts that are providing important insights about the archaeology of the Chachapoya people that established in this area around 900 A.D. up to the Inca conquest of this territory around the year 1475. The mummies recovered showed evidence of cultural practices devised and used to assure the preservation of the human bodies. Such practices are also reported among Chinchorro and Chiribaya mummies in the Andes. A cultural interpretation of these funerary activities is discussed connecting the practice of the cult to the ancestors to the access and management of resources and territory. / En 1997, unos peones descubrieron y huaquearon un cementerio intacto en el bosque nuboso del noreste del Perú. Un rápido proyecto de rescate arqueológico permitió la recuperación de una importante colección de momias y artefactos que están proporcionando importante información sobre la arqueología de los chachapoya. Este grupo se estableció en el área alrededor del 900 d.C. hasta la conquista inca de este territorio, que ocurrió alrededor del año 1475. Las momias recuperadas muestran evidencias de prácticas culturales diseñadas y empleadas para asegurar la conservación de los cuerpos. Prácticas similares se han reportado también entre las momias chinchorro y chiribaya en los Andes. En este artículo se discute una interpretación cultural de estas actividades funerarias relacionando la práctica del culto a los ancestros con el acceso y manejo de los recursos y del territorio.
