Cette thèse propose une redéfinition de la notion de frontière dans le contexte américain, avec pour point de départ les romans de trois voix littéraires issues de trois minorités ethniques : Sandra Cisneros (Caramelo), Cristina Garcia (The Agüero Sisters) et David Plante (The Family et The Native). Je conceptualise la frontière comme fluctuation entre mouvement et immobilité, entre porosité et imperméabilité. Dans le premier chapitre, je fournis des repères sur la théorie des frontières et j'analyse les avancées de ce champ d'étude, du concept de terre frontalière (“Borderland Theories”) jusqu'aux récits d'immigration. Je propose un cadre conceptuel que j'appelle « Écrire la frontière à partir de la perspective de la frontière », lequel permet une lecture neuve des récits de frontière, et une redéfinition de la notion elle-même. Prise comme perspective, la frontière est une dynamique vivante, ce qui la rend plurielle et impossible à fixer définitivement; aussi les récits de frontière présentent-ils une grande variété d’expériences, toutes liées à des moments et à des points de vue uniques. Dans le second chapitre, j’analyse la porosité des frontières dans le contexte géopolitique contemporain, en mettant en lumière comment la colonisation, la mondialisation économique et l’immigration sont autant de mécanismes de transgression des frontières qui suivent des orientations transnationales, dénationales et postnationales. Dans le troisième chapitre, j’étudie la résurgence des frontières dans la vie des immigrants qui habitent aux États-Unis. J’identifie l’insécurité capitaliste ainsi que la marchandisation de l’espace et de l’ethnicité comme étant à l'origine du renforcement des frontières délimitant les quartiers ethniques; génératrices de stéréotypes négatifs, ces divisions physiques deviennent une technologie d’exclusion et d’injustice sociale. Le dernier chapitre présente une lecture des aspects esthétiques de la frontière, voyant comment ils peuvent contribuer à écrire la frontière à partir de la perspective de la frontière. Dans les textes à l'étude, j'examine de près la problématisation du concept de représentation, la multiplicité des points de vue narratifs, l’inaccessibilité du réel, et la partialité de la médiation.

The populations of many species are structured such that mating is not random and occurs between members of local patches. When patches are founded by a single female and all matings occur between siblings, brothers may compete with each other for matings with their sisters. This local mate competition (LMC) selects for a female-biased sex ratio, especially in species where females have control over offspring sex, as in the parasitic Hymenoptera. Two factors are predicted to decrease the degree of female bias: (1) an increase in the number of foundress females in the patch and (2) an increase in the fraction of individuals mating after dispersal from the natal patch. Pollinating fig wasps are well known as classic examples of species where all matings occur in the local patch. We studied non-pollinating fig wasps, which are more diverse than the pollinating fig wasps and also provide natural experimental groups of species with different male morphologies that are linked to different mating structures. In this group of wasps, species with wingless males mate in the local patch (i.e. the fig fruit) while winged male species mate after dispersal. Species with both kinds of male have a mixture of local and non-local mating. Data from 44 species show that sex ratios (defined as the proportion of males) are in accordance with theoretical predictions: wingless male species < wing-dimorphic male species < winged male species. These results are also supported by a formal comparative analysis that controls for phylogeny. The foundress number is difficult to estimate directly for non-pollinating fig wasps but a robust indirect method leads to the prediction that foundress number, and hence sex ratio, should increase with the proportion of patches occupied in a crop. This result is supported strongly across 19 species with wingless males, but not across 8 species with winged males. The mean sex ratios for species with winged males are not significantly different from 0.5, and the absence of the correlation observed across species with wingless males may reflect weak selection to adjust the sex ratio in species whose population mating structure tends not to be subdivided. The same relationship is also predicted to occur within species if individual females adjust their sex ratios facultatively. This final prediction was not supported by data from a wingless male species, a male wing-dimorphic species or a winged male species.

First discovered by accident in 1884 – and thereafter informally investigated by workmen, nuns and clergy, for several decades – the archaeological site at the Sisters of Nazareth convent in central Nazareth has remained unpublished and largely unknown to scholarship. However, work by the Nazareth Archaeological Project in 2006–10 showed that this site offers a full and important stratified sequence from ancient Nazareth, including well-preserved Early Roman-period and later features. These include a partially rock-cut structure, here re-evaluated and interpreted on the basis of both earlier and newly recorded data as a first-century ad domestic building – perhaps a ‘courtyard house’ – the first surface-built domestic structure of this date from Nazareth to be published, and the best preserved. The site was subsequently used in the Roman period for burial, suggesting settlement contraction or settlement shift.

Two daughters of a nonconsanguineous couple are described. Both present mental retardation, epileptic seizures, congenital atrichia, histologically anomalous skin and abnormal EEG pattern. From a discussion of the literature on atrichia, the forms without involvement of teeth, nails and hidrosis, among which recessive inheritance prevails, are distinguished from each other. None of them coincide with the syndrome described here.

Despite the nomenclature suggested to be a tumor, torus palatinus (TP) is an overgrowth of the bone in the palatal region and represents an anatomic variation. Its prevalence varies among the population studied and its etiology is still unclear; however, it seems to be a multifactorial disorder with genetics and environmental involvement. Surgical removal of the TP is indicated in the following circumstances: (1) deglutition and speech impairment, (2) cancer phobia, (3) traumatized mucosa over the torus, and (4) prosthetic reasons. The aim of this case report is describe cases that occurred in two sisters, emphasizing the genetic etiology of this anatomic variation. In addition, intra-oral exam and computed tomography scan (axial, coronal and sagittal view) provided a detailed assessment of the TP and elimination of other possible diagnoses, furthermore allowed a better analyzes of the anatomic relation with adjacentes structures. No surgical removal was indicated for both cases.

Mutations in solute carrier family 26 (sulfate transporter), member 2 (SLC26A2) gene result in a spectrum of autosomal recessive chondrodysplasias that range from the mildest recessive form of multiple epiphysial dysplasia (rMED) through the most common diastrophic dysplasia (DTD) to lethal atelosteogenesis type II and achondrogenesis IB. The clinical variability has been ascribed to quantitative effect of mutations of the sulfate transporter activity. Here we describe two Brazilian sisters, born to healthy and non consanguineous parents, with Robin sequence, mild shortening of upper and lower limbs, brachymetacarpalia/tarsalia, additional and accelerated carpal ossification, marked genu valgum, and multiple epiphysial dysplasia. This phenotype was intermediate between DTD and rMED, and both girls have a compound heterozygous mutations for the SLC26A2, a Finnish founder mutation (c.-26?+?2T>C), and R279W. This combination of mutations has been observed in individuals with different phenotypes, including DTD, DTD variant, and rMED. The distinct phenotype of our cases reinforces the hypothesis that other factors may be influencing the phenotype as previously suggested.

The chylomicronemia syndrome is well recognized as a rare etiologic factor of acute pancreatitis; however, whether hypertriglyceridemia can cause chronic pancreatitis (CP) remains unclear. We describe the long-time course of 2 brothers with the familial chylomicronemia syndrome caused by identical compound heterozygous mutations in the lipoprotein lipase (LPL) gene with markedly reduced LPL activity. Other etiologic factors were excluded, including mutations in the PRSS1, SPINK1, and CFTR gene. Although both brothers had recurrent acute pancreatitis and the same LPL genotype, CP became evident in only one patient. Progression to CP was associated with a more severe disease course. Thus, the chylomicronemia syndrome may cause CP in the absence of other known causative factors, and similar to alcoholic and hereditary CP, a more severe disease course is associated with disease progression.

Slim Styles and the Brothers of the Light consists of a short novella, intended to be part of a series, introduced by a narrative essay. The work is about the search for identity, the pursuit of happiness, and the struggle to maintain self assurance while finding a place in the world. The story follows the main character as he slowly learns the truth about an organization he joined looking for a sense of value and worth. With his back against the wall he has to return to the home he was taught to be ashamed of, face the friends he left behind, and apologize to the lover he took for granted. The manuscript is a work in progress.
