The thesis deals with intelligence, as a socio-cultural concept that has its own history and development. It thus deconstructs the naturalized notions of a biological "essence" of intelligence, which has not been proved to this day. The scientific and philosophical modes of thinking, that participated in both "inventing" intelligence and its forming, are introduced. The analysis of the primary sources enables to compass the reflection of these dominant scientific approaches towards intelligence in the Czech expert discourses. The thesis also reflects on the important role intelligence has in the assessment of mental norm and disability, and it thus analyses the perception of disability during the defined historical period, including the discourse analysis of the different representations of disability. Key words Intelligence, disability, craniometry, eugenics, pedagogy, medicine, biopower.

L’objet de cette étude est une analyse de 32 individus néolithiques représentés par des crânes et/ou des mandibules mis au jour au Mali et en Mauritanie. Les individus composant l’échantillon ostéoarchéologique sont issus de cinq sites présentant des différences géographiques et chronologiques. En dépit de ces différences, nous nous sommes interrogés sur les liens qui pouvaient exister entre eux. Cette analyse, qui a consisté à reconsidérer les caractères morphologiques des crânes et/ou mandibules, leur variabilité, s’est appuyée sur une technologie nouvelle : l’imagerie médicale et tridimensionnelle. Notre premier objectif a été de tenter de répondre à la question suivante : dans quelle mesure l’anthropologie biologique peut-elle s’enrichir des nouvelles technologies issues du domaine de l’imagerie médicale ? Notre questionnement ne s’est pas arrêté pas à cette perspective méthodologique. En effet, l’échantillon ostéoarchéologique présente une particularité morphologique frappante : l’aspect très robuste présenté par de nombreux individus. Cette robustesse confère un caractère archaïque aux sujets par bon nombre de caractères, et ceci malgré des datations néolithiques. Le second objectif de ce travail a été d’ordre paléoanthropologique et a reposé sur l’étude de cette robustesse. La méthode mise en place a permis d’obtenir 146 mesures par individu (en fonction de l’état de fragmentation de chacun). Il s’est avéré que, non seulement, ce caractère a été constaté, mais qu’il semble plus précisément lié à un élément anatomique, la mandibule, ce qui pourrait être le résultat d’une adaptation de l’appareil manducateur aux contraintes environnementales et alimentaires. / The object of this study is an analysis of 32 neolithic individuals represented by skulls and/or mandibles brought to light in Mali and in Mauritania. The individuals composing the osteoarcheological sample arise from five sites presenting geographical differences and chronological. In spite of these differences, we wondered about the links which could exist between them. This analysis, which consisted in reconsidering the morphological characters of skulls and/or mandibles, their variability, leaned on a new technology : the medical and three-dimensional imaging. Our first objective was to try to answer the following question : to what extent the biological anthropology can increase from new technologies stemming from the domain of the medical imaging ? Our questioning did not stop at in this methodological perspective. Indeed, the osteoarcheological sample presents a striking morphological peculiarity: the very strong aspect presented by numerous individuals. This robustness confers an archaic character on the subjects by a lot of characters, and this in spite of neolithic datings. The second objective of this work was of order paleoanthropological and based on the study of this robustness. The organized method allowed to obtain 146 measures by individual (according to the state of fragmentation of each). It appears that, not only this character was noticed, but it seems more exactly being bound to an anatomical element, the mandible, what could be the result of an adaptation of the manducative system to the environmental and food constraints.

As tomadas radiográficas convencionais ainda são os recursos mais difundidos como exames complementares para o diagnóstico das assimetrias faciais. Hoje, novas técnicas de obtenção de imagem podem fornecer visualizações tridimensionais do complexo craniofacial. Estas, por sua vez, podem eliminar magnificações e demagnificações quando da obtenção de mensurações. A imagem tridimensional, utilizando-se de soluções computacionais, pode ser movimentada em diversas direções. Este recurso favorece a cranioscopia, técnica pela quais grandes e médias assimetrias são reconhecidas em qualquer região do complexo craniofacial. A quantificação de assimetrias menores pode ser reconhecida por mensurações realizadas no biomodelo 3D virtual, ou seja, pela craniometria. Alguns protocolos 3D já foram propostos com a finalidade de qualificar e/ou quantificar a assimetria facial. Este trabalho propõe um novo protocolo 3D que faz uso das novas técnicas de aquisição e tratamento de imagens. Utiliza-se então da tomografia computadorizada e tendo como meta qualificar e quantificar a assimetria facial. Para isso, utiliza-se da marcação de pontos anatômicos verdadeiros, criando condições para que mensurações lineares e angulares sejam realizadas. Assim, assimetrias faciais poderão ser observadas, bem como as respostas individuais aos tratamentos propostos / Abstract: The diagnosis of facial asymmetry has been done using clinical and complementary examinations. The conventional radiographic images have still been the most spread resources as complementary examinations for facial asymmetry diagnosis. Nowadays, new image acquisition techniques can give three dimensional visualizations of the craniofacial complex. This way, it is possible to eliminate magnifications and demagnifications in measurements obtained using conventional radiographic techniques. The three dimensional image, using computational solutions, can be moved in different directions. This capability is favorable to cranioscopy, which is a technique used to recognize big and medium asymmetries in any part of the craniofacial complex. The qualification and quantification of small asymmetries can be done using measurements made in 3D virtual biomodel. Few 3D protocols have been proposed with the aim of qualify and quantify facial asymmetry. This work proposes a new 3D protocol which uses new image acquisition and treatment techniques based on computerized tomography, aimed to qualify and quantify facial asymmetry. To do that, it is used true anatomical landmarks marking process, which gives conditions to make linear, angular, area and volume measurements with positive recognitions and precision. Therefore, small facial asymmetries will be possible to be observer, as well as the individual responses to treatments, been them surgical, orthopedical or orthodontical / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica

Les origines du peuplement de l’île de Madagascar ne sont encore que partiellement explorées à l’heure actuelle. Différentes populations ont contribué au peuplement de l’île, de nombreuses théories sur les origines de ce peuplement ont émergé et varient grandement selon les sources consultées. Selon l’archéologie et l’anthropologie culturelle, l’arrivée des premiers peuples remonterait à deux millénaires avant notre ère et plusieurs strates de vagues migratoires venues d’Afrique et d’Asie se sont succédées. Pour une vision complète du peuplement de toute l’île, ce sont les études en linguistique et en génétique qui ont donné les meilleures pistes en s’orientant vers une origine à prédominance indonésienne plutôt qu’africaine. Il reste cependant à confronter ces données diverses à celles issues de l’approche phénotypique, qui est peu utilisée. Mon objectif est donc d’explorer cette hypothèse à partir des données craniométriques, et ainsi de tester les modèles de peuplement proposés grâce à d’autres approches. Cet échantillon malgache (N=207) a été subdivisé sur la base de diverses données (géographie, ethnies et affiliations linguistiques). Après des analyses intra-groupe et intergroupes, ce dernier a été comparé à d’autres données craniométriques personnelles et publiées (N=1184). Deux types d’approches statistiques (multivariées classiques et issues de l’approche de la génétique des populations ou RMET) ont été utilisées afin d’obtenir des paramètres diversifiés et complémentaires. Les résultats issus des deux approches tendent vers une origine mixte (Afrique et Asie), dont la prépondérance varie en fonction de la région et du sexe. En effet, les hommes malgaches ont une origine triple (sud de l’Asie du Sud-est, sud de l’Afrique et côtes sud-est africaines), alors que les femmes ont plutôt une origine double (Afrique et Asie) selon l’approche multivariée classique. D’après les analyses RMET, on note que les individus des régions du nord et de l’est de l’île se rapprochent des populations de Tanzanie et les Malgaches présentent des similarités avec les populations indiennes. De plus, on remarque que les Malgaches du groupe nord présentent par rapport aux autres groupes un degré d’hétérogénéité plus élevé (Fst). Ce phénomène est dû probablement à des apports de populations plus diverses dès le début du peuplement de l’île dans cette région. Cette étude, basée sur un petit échantillon, confirme néanmoins les thèses antérieures sur la diversité du peuplement malgache et de plus elle démontre que les composantes prédominantes (Afrique ou Asie) varient selon les régions et le sexe. / As of now, origins of the island of Madagascar’s settlement have only been partially investigated. Various populations inhabited the island, thus numerous theories about these origins were devised and explanations vary greatly from source to source. According to archaeology and cultural anthropology, its first settlers came around two millennia before Christ and many waves of migration from Africa and Asia followed in their path. Studies in linguistics and genetics best laid the way for a comprehensive overview of that settlement and pointed to a predominantly Indonesian origin as opposed to an African one. However, comparing these many findings with those obtained through the rarely used phenotypic approach has yet to be done. My goal is therefore to explore this question using craniometric data to test settlement patterns proposed by other fields. Our Malagasy sample (N=207) was subdivided according to various factors (geography, ethnicities and linguistic affiliations). After intragroup and intergroup-based analyses, the sample was compared to more craniometric data, personal and published (N=1184). Two types of statistical approaches (classic multivariate and originating from genetics populations approach, or RMET) were used to achieve diversified and complementary parameters. Results from both approaches support the conclusion that the origins are in fact mixed (Africa and Asia) and their preponderance, linked to region and gender. Indeed, Malagasy men have three sources (south of Southeast Asia, southern Africa and southeast African coast), while women have more of a double origin (Africa and Asia) according to the classic multivariate approach. RMET analyses show that individuals from the northern and the eastern regions of the island share traits with Tanzanian populations as well as similarities with Indian populations. Furthermore, Malagasy from the northern group exhibit higher heterogeneity than other groups (Fst). This phenomenon is likely due to the influx of various populations early in the settlement of the island. This study, based on a small sample, nevertheless confirms previous theses on the diversity of the Malagasy settlement and, in addition, shows that its predominant parts (Africa and Asia) vary according to region and gender.

Interspecific and intraspecific size variability of the skull, mandibles and teeth of the lesser white- toothed shrew Crocidura suaveolens and the bicolored white-toothed shrew C. leucodon was studied on material of 350 skulls and 465 mandibles of white-toothed shrews obtained by analysis of the barn owl pellets originating from four regions in the Czech Republic and one region in the southern Slovakia. C. suaveolens was present in all regions under study, while sympatric C. leucodon occurred in three regions only. In total, 21cranial and dental measurements and 4 mandibular measurements were investigated. It was found that the most reliable measurement enabling discrimination between skulls of both species in the whole studied material is the lenght of the lower dental row. If skulls of both species were evaluated separately for each area of their sympatry it was possible to use also the distance between second molars M2 and the width of premolar P4 . Skulls of these two species can also be distinguished by bivariate graphs using the length and width of premolar P4 and the palatal length. We studied relationships between cranial measurements of both species and geoclimatic factors such as longitude, latitude, mean annual temperature and mean annual percipitation. It was found that variability of...

Antropologia Forense é a aplicação da ciência da Antropologia Física e osteologia humana em casos criminais onde os restos da vítima estão em fase avançada de decomposição. Devido ao grande fluxo migratório descrito no histórico do Brasil, a população brasileira possui características físicas muito heterogêneas quando comparadas com a população escocesa, uma vez que a imigração mais significativa foi proveniente de outras regiões do próprio Reino Unido. O presente estudo teve como objetivo comparar as variações craniométricas de duas populações (brasileira e escocesa), e avaliar a confiabilidade do método para determinação do sexo nas duas populações, com finalidade forense. A amostra total foi composta por 200 crânios com mandíbulas, sendo que a amostra brasileira foi constituída por 100 crânios completos e a amostra escocesa por 100 crânios e 36 mandíbulas, ambas amostras documentadas. Foram realizadas 72 mensurações sendo 51 cranianas e 21 mandibulares. Os resultados demonstraram que a amostra escocesa apresentou média maior comparada com a amostra brasileira em 54 variáveis do universo de 72 medidas. Trinta e três mensurações cranianas apresentaram diferença significativa entre as duas amostras e dentre as 21 medidas mandibulares analisadas, 05 apresentaram variação superior a 20%, 09 entre 10% e 20%, 07 inferior a 10%. As medidas que apresentaram maior dimorfismo sexual para as duas amostras foram a largura bizigomática (apresentando 73% de acerto para a amostra brasileira e 77% para a amostra escocesa), largura bigoníaca (79% e 83,30%) comprimento Porion-Mastoidale lado esquerdo (76% e 75%) e a altura do corpo mandibular lado esquerdo (67% e 80,60%). A análise discriminante multivariada demonstrou resultados satisfatórios para amostra brasileira com porcentagem de acerto variando entre 76-90% e na amostra escocesa 81-86,6%. Através da análise da curva ROC foram desenvolvidas 04 tabelas de referência sendo 01 para medidas cranianas brasileiras, 01 medida para mandibulares brasileiras, 01 tabela para medidas cranianas escocesas e 01 para medidas mandibulares escocesas. O presente estudo demonstrou que existem diferenças entre as duas amostras estudadas, porém ainda falta elucidar a causa responsável, já que se trata de uma grandeza multifatorial. A metodologia quantitativa analisada demonstrou-se precisa para analisar dimorfismo sexual nas duas amostras. / Forensic anthropology is the application of the physical anthropology science and human osteology in criminal cases where the victim\'s remains are in an advanced stage of decomposition. Due to migration Brazilian population is very diverse, comprising many races and ethnic groups, therefore it is much more varied than the Scottish population, which tends to be more homogenous once there was significant immigration to Scotland from the rest of the United Kingdom. The present study aimed to compare the craniometric variations of two populations (Brazilian and Scottish), and analyze the reliability of sex determination in the two populations for forensic purpose. The total sample was comprised of 200 skulls and 136 mandibles, the Brazilian sample consisted of 100 complete skulls and the Scottish sample was composed of 100 skulls and 36 mandibles, both of which are documented samples. The measure\'s protocol comprised 72 measurements, being 51 cranial and 21 mandibular. The results showed that the Scottish sample had a larger mean compared to the Brazilian sample in 54 variables of the 72 measures. Among the cranial measurements analyzed, 33 variables showed a significant difference between the two samples and among the 21 mandibular measurements considered, 05 presented a variation greater than 20%, 09 between 10% and 20%, 07 lower than 10%. The most dimorphic measurements for both samples were the bizigomatic width (73% of accuracy for the Brazilian sample and 77% for the Scottish sample), the bigoniac width (79% and 83,30%), the Porion-Mastoidale length (76% and 75%), and the left side mandibular body height (67 and 80,60%). The multivariate discriminant analysis showed satisfactory results for the Brazilian sample with a percentage of accuracy varying between 76-90% and in the Scottish sample 81-86.6%. Through the analysis of the ROC curve, four reference tables were developed: 01 for Brazilian cranial measurements, 01 Brazilian mandibular measurements, 01 Scottish cranial measurements and 01 Scottish mandibular measurements The present study showed a difference between the two samples studied, but it is not possible to define an unique cause responsible for that because this comprise multifactorial aspects. The quantitative methodology analyzed showed sexual dimorphism in both samples.

This thesis presents a three-dimensional computed tomography (3D-CT) analysis of craniofacial morphology and growth changes in Malaysian Malay subjects. A large number of CT scans (n=205) from birth to adulthood were gathered for this purpose. CT scans were obtained using a GE Lightspeed Plus Scanner. Craniofacial morphology has been analysed based on cephalometric landmarks located in three-dimensions, using specially-designed computer software. The main aims were to produce new 3D normative reference data for selected craniofacial variables in Malaysian Malays and to study growth changes in different craniofacial regions. The specific areas of investigation included: 1. Construction of craniofacial growth references (in tabular and graphical formats) for Malaysian Malays; 2. Quantitative analysis of growth changes in the craniofacial complex using linear and angular measurements derived from landmark data; 3. Comparison of craniofacial measurements between males and females to determine the extent of sexual dimorphism; 4. Quantitative analysis of the nature and extent of directional asymmetry of selected craniofacial regions; 5. Comparisons of selected variables with published data from other ethnic groups. Craniofacial morphology and growth changes were analysed using 3D osseous landmarks. A computer program, PERSONA, was used to locate and analyse the three-dimensional cephalometric landmarks. The accuracy of landmark location was assessed using double determinations. Selected measurements were derived from the landmark data to describe the morphology of different craniofacial regions, e.g. facial skeleton, cranial base and cranial vault. Normative reference data for a large number of variables covering the skull, cranial base and face at selected age categories for males and females were constructed. These data were presented in tables and scatter plots of variables against age. From the normative data collected, patterns of growth changes of different craniofacial regions in three-dimensions were also investigated. Generally, each craniofacial region showed a unique growth pattern as observed from differential growth patterns. All measurements showed size increase from infancy to adulthood. Periods of increased size differences were also noted for most variables in all regions that corresponded to the timing of mid- and adolescent growth spurts. These extensive normative reference data, specific for age categories and sexes, provide normal references against which the craniofacial morphology of individuals with craniofacial abnormalities can be compared. Clinical applications of this quantitative approach to the craniofacial skeleton should facilitate the management of craniofacial abnormalities. Following the construction of normative data and description of growth changes for different craniofacial regions, intra-populational differences were studied. This included analysis of sexual dimorphism of the craniofacial structures and an investigation of asymmetry between paired left and right measurements. Sexual dimorphism was observed for linear variables in this study. Differences in size between males and females were not very obvious during infancy as only a few variables showed significant differences. The number of variables that showed sexual dimorphism in size increased from infancy to adulthood. Sexual dimorphism in the craniofacial region was most evident during adulthood with 46% of variables displaying significant differences between the sexes. During infancy, only 3% of the variables showed significant size differences between the sexes, increasing to 7% during childhood. Magnitudes of sexual dimorphism were calculated to highlight the pattern of dimorphism in different craniofacial regions and across different ages. A small degree of directional asymmetry was noted in all of the craniofacial regions investigated. Asymmetry analysis revealed that the cranial base, face and mandible tended to be larger on the right side than the left. Other regions exhibited asymmetry but without any clear trend in direction. Asymmetry percentages were also calculated to enable the patterns and magnitudes of asymmetry in different craniofacial regions to be compared. Generally, the amount of asymmetry exhibited in the craniofacial structures for Malaysian Malays was small. Having established that differences existed within the Malay sample, craniofacial data for Malays were compared with published data for two Caucasian populations. This analysis revealed that differences exist in craniofacial morphology between different ethnic groups. Some of the differences can be discerned from childhood but many variables only display differences during adulthood. Craniofacial structures tended to be smaller in Malays than in Caucasians. The intent of this investigation has been to provide clinicians with normative values of measurements that will be useful in diagnosis, treatment planning and post-operative care of patients with craniofacial abnormalities. Important treatment goals include producing balanced cranial and facial form to approximate that of unaffected people and also improving the quality of life of patients. Therefore, it is important for clinicians to be able to recognise the nature and extent of normal variation in craniofacial structures and also appreciate the growth changes that may occur over time, before investigating these changes in patients with craniofacial abnormalities. Comparisons of measurements of affected patients with well-characterised referent data can facilitate diagnosis and overall patient management. Moreover, quantification based on three-dimensional data provides new insights into craniofacial growth changes and morphology compared with conventional 2D approaches. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1280892 / Thesis (Ph.D.) -- Dental School, 2007.
