Estudos filogenéticos da ‘ordem’ resultaram em topologias com baixa resolução devido à falta de informação acerca de alguns táxons e sinais de exaustão de caracteres ao longo da evolução de suas famílias. Dentre elas, a família Cassiulidae é composta por cinco a seis gêneros e pouco se sabe sobre o relacionamento entre seus gêneros, visto que análises ao nível de ordem incluíram poucas espécies desta família. Neste trabalho foram realizadas análises cladísticas para propor uma hipótese de relações filogenéticas entre os gêneros da família Cassidulidae. A análise principal incluiu 16 cassidulídeos e 33 caracteres morfológicos. As análises seguintes tiveram como objetivo verificar a influência dos dados faltantes e da inclusão de táxons fósseis na topologia encontrada. Cada uma das três análises resultou em uma única árvore mais parcimoniosa, em geral, bem resolvida. As relações de parentesco foram: (Eurhodia relicta (demais Eurhodia) + ((Australanthus + Cassidulus malayanus) + (Paralampas (Cassidulus + Rhyncholampas)))). Tanto a quantidade de dados faltantes quanto a exclusão de espécies fósseis não afetaram negativamente a resolução da árvore. Os resultados obtidos indicaram a necessidade de estudar a taxonomia, principalmente, dos gêneros Eurhodia, Cassidulus e Rhyncholampas e a exclusão de Cassidulus malayanus e Eurhodia relicta dos seus respectivos gêneros. Possíveis ocorrências de processos heterocrônicos foram detectadas, a exemplo da evolução do gênero Rhyncholampas por peramorfose e do gênero Paralampas por pedomorfose. Os cassidulídeos provavelmente se originaram no Cretáceo Tardio e novidades não foram adicionadas à sua evolução. Como resultado, processos heterocrônicos devem ter desempenhado um papel importante na diversificação da família. Evidências de processos heterocrônicos obtidas a partir da análise atual foram discutidas. Finalmente, um cenário paleobiogeográfico dos cassidulídeos foi proposto, com origem Tetiana e dispersão inicial, seguida por expansão e vicariância. / Salvador

Although Yimas has many complex verbal constructions, including three kinds of serial verb constructions, all three novel constructions, it is argued, were reanalyzed from juxtaposition serial verb constructions (JSC). The construction specific semantics, as well as the specific verbal semantics of tal 'hold', tmi 'say' and tay 'see' contributed to reanalysis. It is notable that three new constructions have developed from a single source construction. I argue that the iconic closeness of the JSC helped motivate this reanalysis. It also appears possible that other derivational morphology in Yimas has developed through this route. I argue that the development of derivational morphology in Yimas is different than the development of inflectional morphology. The tight, and iconically close, relationship of juxtaposition appears to be a possible motivating factor. / Committee in Charge: Prof. Spike Gildea, Chair; Prof. Doris L. Payne

The current study examined the relation of impulsivity and obesity in three neuroimaging studies using MRI techniques to test the hypothesis that deficits in brain regions responsible for inhibitory control are associated with obesity. The first study used voxel-based morphometry (VBM) to explore volumetric differences in lean, overweight, and obese women (N=83) and found that BMI was negatively correlated with grey matter (GM) in the insula, frontal operculum, and inferior frontal gyrus. BMI was positively correlated with white matter (WM) in the fusiform gyrus, parahippocampal gyrus, Rolandic operculum, and dorsal striatum. Genetic alleles for dopamine expression moderated these relations. Additionally, less GM in the superior frontal gyrus predicted future increases in BMI. The second study used VBM to examine differences between lean adolescents at risk versus not at risk for obesity (N=54). There were no regional GM or WM differences based on risk status. There were also no regional differences that predicted weight gain over 1-year follow-up. Additionally, genetic alleles for dopamine expression did not moderate any of these regions. These findings suggest that volumetric differences may emerge after excessive weight gain. Finally, the third study used a psychophysiological interaction analysis to test functional connectivity between prefrontal and limbic regions as a function of BMI in lean, overweight, and obese women (N=37) during a go/no-go task. There was no functional connectivity found in seed regions in relation to BMI. Implications for intervention and future research are discussed.

The Rarómuri, or Urique Tarahumara (UT), language belongs to the Taracahitian sub-branch of the Uto-Aztecan family. There are five major linguistics variants called Tarahumara, all spoken in Chihuahua state in northern Mexico. This dissertation is an introduction to how both verbal and nonverbal predicates are formed in the language of the Rarómuri people, as spoken in Urique, Chihuahua. The central contribution of this dissertation is found in Chapter IV on nonverbal predication and Chapter V on verbal predication, and the work opens with three chapters: Chapter I is the introduction, Chapter II introduces the orthography and some of the most common morphophonological processes, and Chapter III sketches the morphology and syntax of the Noun Phrase. Chapter VI concludes the dissertation with a discussion of directions for future research. This dissertation is based on a combination of recorded texts and elicited material. The texts provided the natural language where the constructions in question occur in actual use, providing the motivation and signaling directions for elicitation, which then allowed the understanding of the intricate morphological patterns. Both types of data material are invaluable for the researcher, and I include examples of both when possible. One point of typological interest in UT is the verbal indexation system for subjects in the past tense, which includes suffixes for 3SG/PL and 1PL, zero marking (fused with the tense suffix) for 2PL, and verbal enclitics for 1SG and 2SG. The verbal enclitics also occur marking future tense verbs. The verbal enclitics for 1SG and 2SG can also mark object, and alone among core arguments, the 1SG free pronoun object must take a locative suffix. Looking at person marking and object case, it appears that UT has an incipient hierarchical system, with 1SG > 2SG > 1PL/2PL/3. Another of the most salient features of UT is the morphophonology. It is common in UT for a morpheme to present several allomorphs, and some, like the Potential Future, can have up to 9 allomorphs. Some of this allomorphy is phonologically conditioned, other allomorphy is lexically conditioned, and other allomorphy is clearly suppletive. The interaction of these conditioning factors is possible.

The functional morphology of the heart/kidney complex, digestive system and mantle was investigated in Dentalium rectius (Mollusca, Scaphopoda). While encompassing in-depth examination of the diverse roles of each organ system, these studies also contribute towards an overview of metal processing by the organism. The heart/kidney complex departs substantially from typical molluscan form; morphological features demonstrate that the heart is reduced to a perianal sinus adjacent to the pericardium. Excretory function appears to be maintained, however, pericardial podocytes and a right renopericardial connection indicate that a blood ultrafiltrate passes to the kidney. Urine is modified by two nephrocyte types. While one may effect reabsorption, both secrete calcium, zinc and phosphate-containing granules into the urine. Intracellular granules of the digestive system also contain calcium phosphate; iron is the only other metal accumulated, principally by oesophageal and stomach epithelia. Iron uptake occurs via digestive cells and by both undifferentiated and specialized mantle epithelia. Iron-containing granules, released into the haemocoel by the mantle epithelium, are phagocytosed and transported by amoebocytes. Iron is not excreted by the kidney, but by oesophageal secretion into the gut lumen and by radular mineralization, differing significantly from iron processing reported in other molluscs. In addition to iron uptake, mantle functions include the creation of respiratory currents, gas exchange and sensory reception; the respective epithelial specializations described here constitute functional equivalents to ctenidia and osphradia, organs which are absent in this molluscan class. The ciliated bands of the mid-mantle region include supporting cells which possess high-domed, microvillous apices that facilitate diffusion between the mantle cavity and underlying haemocoel. The posterior region of the mantle is richly endowed with innervated cells, considered putative sensory receptors. Cilia number, length and ultrastructure define three receptor types. They are heterogeneously distributed among specific regions of the pavilion, and probably function in respiratory current testing. The maintenance of respiratory current passage to the scaphopod mantle cavity requires a secondary increase in posterior aperture size, which is otherwise progressively diminished by normal shell growth. Such an increase occurs in D. rectius, and is effected by periodic shell decollation through dissolution by the posterior mantle. / Graduate

Sete resinas compostas indicadas para restaurações de dentes anteriores e posteriores foram selecionadas para este estudo (Charisma/Kulzer, Opallis/FGM, Esthet-X/Dentsply, 4Season/Ivoclar, Z250/3M ESPE, Z350/3M ESPE e P90/3M ESPE). Foram confeccionados cinqüenta e um corpos-deprova de cada material com 4 mm de diâmetro e 2 mm de espessura com auxílio de uma matriz de elastômero. Após a fotoativação por 40 segundos (Elipar Free-Light/3M ESPE), os corpos-de-prova foram armazenados em água destilada por 24h a 370C para posterior realização do polimento superficial com discos Soft Lex/3M ESPE na granulação fina e extrafina. Em seguida, os corpos-de-prova foram secos com papel absorvente e a rugosidade de superfície foi mensurada por meio de rugosímetro. Os corpos-de-prova foram então divididos aleatoriamente em cinco grupos (n=7) de acordo com as soluções testadas: G1- Água destilada (pH 5,30); G2 - Vinho tinto/ Trapiche Syha Ind. Argentina (pH 3,68); 3 - Coca-cola®/ Ind. Coca-cola LTDA (pH 2,73); 4 - Suco de laranja/ Purity Cocamar (pH 3,58) e G5 - Solução tampão lactato (2,74). As soluções testadas foram trocadas diariamente. O teste de rugosidade de superfície foi repetido após 15, 90 e 180 dias de imersão. Os valores médios da rugosidade de superfície foram submetidos à análise LSmeans e teste de Tukey-Kramer, em nível de significância de 5%. Os resultados de rugosidade de superfície revelaram que as resinas compostas que apresentaram aumento de rugosidade estatisticamente significativo para todos os períodos e soluções foram Opallis, Esthet-X, 4Season e Charisma. Um corpo-de-prova de cada resina composta foi selecionado para análise morfológica de superfície após 24h, 15, 90 e 180 dias, com microscopia eletrônica de varredura (JEOL- JSM 5600, Tokyo, Japão), numa ampliação de 3000X para revelar as alterações da micro-estrutura de superfície. A análise morfológica de superfície mostrou que as resinas compostas Z350 e P90 foram as mais resistentes à ação das diferentes soluções para os períodos analisados. Enquanto que para as demais resinas compostas foi observada a extrusão das partículas de carga caracterizada por porosidades ou também seu desprendimento permanecendo expostas na superfície. Com base nos resultados pôde-se observar que a degradação superficial das resinas compostas é dependente de sua composição, tempo de armazenamento e do pH da solução. / Abstract: The aim of this study was to evaluate in vitro of superficial roughness and surface morphology of composite resins stored 180 days in acid and alcoholic solutions present in the diet. Seven composite resins indicated for the previous and posterior teeth restorations were selected for this study (Charisma / Kulzer, Opallis / FGM, Esthet-X/Dentsply, 4Season/Ivoclar, Z250/3M ESPE ESPE and Z350/3M P90/3M ESPE). Fifty one specimens were made proof-of-each material with 4 mm in diameter and 2 mm thick with elastomer matrix aid. After curing for 40 seconds, the specimens were stored in distilled water for 24h at 370C for subsequent accomplishment of the superficial polishing with disks Soft Lex/3M ESPE and in the thin and extra thin granulation. Then the specimens were proof-of-dry with paper towels and the superficial roughness was measured using a rugosimeter. Specimens were then randomly divided into five groups according to the tested solutions: G1- Distilled water (pH 5,30) G2 - Red Wine / Argentina Trapiche SYHA Ind. (pH 3,68); G3 - Coca-Cola ® / Coca-Cola Ind. LTDA (pH 2,73); G4 - Orange Juice / Purity Cocamar (pH 3,58) and G5 - lactate buffer (pH 2,74). The superficial roughness test was repeated after 15, 90 and 180 days of immersion. The average values of the superficial roughness were statistically analyzed by LSmeans test and Tukey-Kramer test at a significant level of 5%.The results showed that the composite resins that statistically significant increase in roughness for all periods and solutions were Opallis, Esthet-X, 4Season and Charisma. One specimen more representative of each compound resin was selected for morphological analysis of surface after 24, 15, 90 and 180 days. This analysis was made using scanning electron microscopy (JEOL JSM-5600, Tokyo, Japan) at a magnification of 3000X to expose changes in the superficial micro structure. The surface morphology showed that the composite resins Z350 and P90 were more resistant to the action of different solutions for the periods analyzed. The other composite resins were observed displacement of charged particles or porosities also characterized by its detachment staying loose on the surface. Based on the results it was observed that the surface degradation of compound resins is dependent of its composition, storage time and pH solution. / Doutorado / Materiais Dentarios / Doutor em Materiais Dentários
