'A piece of fine meshwork': the intertwining fiction of Philip Roth and Edna O'Brien

This thesis comprises a comparative analysis of the works the Irish author Edna O’Brien and her contemporary and friend, the Jewish-American author Philip Roth. It investigates the striking biographical, textual and stylistic symmetries between two writers from very different cultures and literary traditions. The thesis begins with the, until now, undetected intertextual nexuses between Roth’s fiction and O’Brien’s. These allusions significantly alter the readings of a number of their novels, while at the same time indicating wider transatlantic frames of reference now apparent in their work. O’Brien has, since the beginning of her career, been in frequent correspondence with all of the pre-eminent Jewish-American authors of her time, and her work conducts a dialogue with key Jewish-American texts. Conversely, Roth’s fiction—like O’Brien’s, obviously indebted to Joyce—has frequently alluded to other seminal Irish authors. The literary and personal relationship of Roth and O’Brien symbolize myriad links between Jewish and Irish literary cultures. In O’Brien’s (and wider Irish) fiction, the Jew is often positioned as an exotic but dangerous “Other”. Equally, throughout the Jewish canon Irish Catholics are frequently employed as foils. Roth and O’Brien investigate difference by depicting relationships that cross these boundaries. Through understanding the complex interrelations at play between the fiction of Roth and O’Brien, and between their work and that of a wider pantheon of Irish and American writers, this thesis will reposition both as transnational authors while developing a culturally sensitive, textually nuanced account of their transatlantic literary relations.

Fine tuning for the tropics: application of eDNA technology for invasive fish detection in tropical freshwater ecosystems

Invasive species pose a major threat to aquatic ecosystems. Their impact can be particularly severe in tropical regions, like those in northern Australia, where >20 invasive fish species are recorded. In temperate regions, environmental DNA (eDNA) technology is gaining momentum as a tool to detect aquatic pests, but the technology's effectiveness has not been fully explored in tropical systems with their unique climatic challenges (i.e. high turbidity, temperatures and ultraviolet light). In this study, we modified conventional eDNA protocols for use in tropical environments using the invasive fish, Mozambique tilapia (Oreochromis mossambicus) as a detection model. We evaluated the effects of high water temperatures and fish density on the detection of tilapia eDNA, using filters with larger pores to facilitate filtration. Large-pore filters (20 μm) were effective in filtering turbid waters and retaining sufficient eDNA, whilst achieving filtration times of 2-3 min per 2-L sample. High water temperatures, often experienced in the tropics (23, 29, 35 °C), did not affect eDNA degradation rates, although high temperatures (35 °C) did significantly increase fish eDNA shedding rates. We established a minimum detection limit for tilapia (1 fish/0.4 megalitres/after 4 days) and found that low water flow (3.17 L/s) into ponds with high fish density (>16 fish/0.4 megalitres) did not affect eDNA detection. These results demonstrate that eDNA technology can be effectively used in tropical ecosystems to detect invasive fish species. © 2016 John Wiley & Sons Ltd.

Variables Associated With The Performance Of Centers For Dental Specialties In Brazil.

The aim of this study was to evaluate the performance of the Centers for Dental Specialties (CDS) in the country and associations with sociodemographic indicators of the municipalities, structural variables of services and primary health care organization in the years 2004-2009. The study used secondary data from procedures performed in the CDS to the specialties of periodontics, endodontics, surgery and primary care. Bivariate analysis by χ2 test was used to test the association between the dependent variable (performance of the CDS) with the independents. Then, Poisson regression analysis was performed. With regard to the overall achievement of targets, it was observed that the majority of CDS (69.25%) performance was considered poor/regular. The independent factors associated with poor/regular performance of CDS were: municipalities belonging to the Northeast, South and Southeast regions, with lower Human Development Index (HDI), lower population density, and reduced time to deployment. HDI and population density are important for the performance of the CDS in Brazil. Similarly, the peculiarities related to less populated areas as well as regional location and time of service implementation CDS should be taken into account in the planning of these services.

Vasopressina e morte encefálica

Brain death results in the breakdown of effective central regulatory mechanisms of cardiocirculatory stability, even in patients with artificial mechanical ventilation, correction of electrolytic and acid-basic disorders and maximal conventional pharmacological support of the circulation. Recent evidences have shown that the fall of vasopressin levels in the blood circulation significantly influences the cardiocirculatory stability of patients with brain death, and its exogenous administration is defended by many authors for the management of multiorgan donor patients. In this brief review we analyse and discuss some experimental and clinical relevant studies about the role of vasopressin in the control of cardiocirculatory stability in brain death, and its potential usefulness in the management of multiorgan donor. We conclude that the role of vasopressin in the pathophysiology of brain death and its usefulness as a pharmacological agent in the management of multiorgan donor are not well elucidated, deserving further investigations.

A motivação de alunos no contexto da progressão continuada

This study investigated the intrinsic and extrinsic motivacional orientations of students in the context of the educational continuous progression. The sample was composed of 160 subjects of second, fourth, sixth and eighth grades of the elementary school. Data was collected by means of the presentation of histories involving the intrinsic, extrinsic motivation and the educational continuous progression system. Subjects were interviewed individually. Their answers were transcribed verbatim and submitted to content analysis. Results indicated that a expressive percentage of students did not know the educational system of continuous progression. Students revealed a predominantly intrinsic motivation orientation with advances in age and in school grade level, even though knowing that they will not repeat any school grade. This study pointed out the importance of deepening our knowledge concerning the impact of the educational continuous progression in students' motivation to learn.

A construção de uma escala de estratégias de aprendizagem para alunos do ensino fundamental

Although learning strategies are important tools for schooling process, there is a lack of national instruments to evaluate their knowledge by brazilian students. Therefore, the objectives of this paper are to describe the steps necessary for the construction of a scale to evaluate the learning strategies for basic education students and to present the preliminary study of its psychometric properties. It is also discussed the utility of this instrument for diagnosis, intervention and prevention in school and educational psychology.

Hidrocefalia multiloculada: relato de dois casos

Multiloculated hydrocephalus is a clinicopathological entity consisting of enlarged, loculated ventricles and paraventricular poroencephalic cavities. We present two cases of multiloculated hydrocephalus: one due to infectious process of central nervous system and the other consequent to a congenital malformation. Tomographic aspects of this condition that permit the diagnosis are stressed. The pathophysiology, the management and the prognosis are discussed according to the available literature.

Expression of SMAD proteins, TGF-beta/activin signaling mediators, in human thyroid tissues

OBJECTIVE: To investigate the expression of SMAD proteins in human thyroid tissues since the inactivation of TGF-β/activin signaling components is reported in several types of cancer. Phosphorylated SMAD 2 and SMAD3 (pSMAD2/3) associated with the SMAD4 induce the signal transduction generated by TGF-β and activin, while SMAD7 inhibits this intracellular signaling. Although TGF-β and activin exert antiproliferative roles in thyroid follicular cells, thyroid tumors express high levels of these proteins. MATERIALS AND METHODS: The protein expression of SMADs was evaluated in multinodular goiter, follicular adenoma, papillary and follicular carcinomas by immunohistochemistry. RESULTS: The expression of pSMAD2/3, SMAD4 and SMAD7 was observed in both benign and malignant thyroid tumors. Although pSMAD2/3, SMAD4 and SMAD7 exhibited high cytoplasmic staining in carcinomas, the nuclear staining of pSMAD2/3 was not different between benign and malignant lesions. CONCLUSIONS: The finding of SMADs expression in thyroid cells and the presence of pSMAD2/3 and SMAD4 proteins in the nucleus of tumor cells indicates propagation of TGF-β/activin signaling. However, the high expression of the inhibitory SMAD7, mostly in malignant tumors, could contribute to the attenuation of the SMADs antiproliferative signaling in thyroid carcinomas.
