Endocrine disrupting compounds (EDC) are environmental contaminants that disrupt reproduction, development and behaviour in aquatic organisms. A thorough evaluation of the impacts of EDCs on aquatic organisms is currently limited by a lack of robust biomarkers in small model fish, particularly for assessing EDCs with (anti-)androgenic activity. Male sticklebacks build nests using spiggin, an androgen-responsive glycoprotein, which can be used to assess (anti-)androgenic exposure. EDC assessment in the field using threespine stickleback and the spiggin biomarker is limited to coastal and estuarine environments. However, their freshwater relative, brook stickleback (Culaea inconstans), also possess spiggin and their widespread distribution suggests that they may have applications as a bioindicator of EDCs in freshwater systems. Therefore, the overall objective of this thesis was to determine if brook stickleback are a suitable bioindicator species for EDCs by evaluating their response and sensitivity to estrogenic and (anti-)androgenic chemicals. Basal transcript levels of spiggin in kidney and vitellogenin in liver were first measured in wild-caught brook stickleback using qPCR and found to be differentially expressed in males and females. Brook stickleback were then exposed to two model compounds, 17α-ethinylestradiol (EE2) and 17α-methyltestosterone (MT), at 1, 10 and 100 ng/L for 21 days (sampled at 7 and 21 days) via static-renewal to determine the responsiveness of these transcripts to exogenous hormones. The effect of hormone exposure on condition factor, organosomatic indices and histopathology of kidneys was also measured. Exposure to MT and EE2 significantly induced spiggin and vitellogenin transcripts in female kidneys and male livers, respectively. Exposure to EE2 also significantly increased the hepatosomatic index in females after 7 days and in both sexes after 21 days whereas the gonadosomatic index was reduced in females after 21 days. An increase in kidney epithelium cell height was also observed in MT-exposed females and males after 7 days. These results mirror those of threespine stickleback and suggest that brook stickleback are responsive to androgenic and estrogenic chemical exposure and more specifically, possess quantifiable and sensitive biomarkers for exposure to compounds with androgenic activity. In a third experiment, female fish were co-exposed to MT at 500 ng/L and an anti-androgen (flutamide; FL) at 25, 150 and 250 µg/L for 14 days (sampled at 4 and 14 days) to validate this bioassay for the evaluation of anti-androgens using the same endpoints as in the previous two experiments. In females, exposure to MT increased spiggin transcript levels and nephrosomatic index (NSI) but co-exposure to FL did not result in a significant suppression of these endpoints because of high inter-individual variability. In males, exposure to MT increased NSI and co-exposure to FL resulted in a reduction in this endpoint, illustrating anti-androgenic effects. Although the response of brook stickleback to hormone exposure was endpoint-specific and was at times lower than other small model fish species, the ability to simultaneously assess estrogenic and (anti-)androgenic chemical exposure in a single fish using quantitative endpoints is an advantage exclusively held by members of the stickleback family. The results of this thesis suggest that brook stickleback hold promise as an additional small fish model for the evaluation of EDCs, with potential application in EDC biomonitoring in the freshwaters of North America.

This work is concentrated on the period of ?Theatre of Cruelty? and following theatre experiments in work of Peter Brook. It´s historical basis are years 1963-1970 and it explores the influences of Antonin Artauds theories on Brooks praxis, areas, where these men encountered. Main goal of this work is to reflect confrontaion of Artauds ideas with practical theatrical process and to tell, how much were they real and how much not: to explain their contribution to theatre.

Como ponto inicial para esta tão complexa discussão, partimos de um estudo do conceito de Centelha da Vida (termo metafórico criado pelo diretor inglês Peter Brook para falar sobre a ¿vida¿ que emana de uma cena e a torna interessante e envolvente para quem a assiste) e ampliamos, postumamente, a discussão para outros autores como: Stanislavsky, Grotowski e Burnier. Para tanto, adotamos o pressuposto do ator como uma corporeidade que se relaciona com outras corporeidades (que no caso seriam os demais atores e o público) utilizando como suporte as teorias de Merleau-Ponty e os estudos de Antônio Damásio sobre corpo e mente. Como forma de investigação, propomos duas frentes de laboratórios práticos de criação: a pesquisa com a linguagem de sinais aplicada à cena e uma observação e análise do processo de criação da peça ¿Intersecções: peças curtas de Harold Pinter¿. O intuito de tais laboratórios foi efetuar uma investigação sobre a questão da organicidade da representação do ator, aproveitando a semelhança entre as essências dos conceitos de Centelha da Vida, verdade teatral e organicidade / Abstract: This work aims to carry out a series of reflections on the phenomenon of the presence of ¿life¿ during the actor¿s performance. As a starting point for such a complex discussion, we consider the study of the concept Spark of Life (a metaphorical term minted by English director Peter Brook to describe the ¿life¿ which emanates from a scene making it interesting and involving for the audience) further extending the discussion to other authors such as: Stanislavsky, Grotowski, and Burnier. In order to accomplish our objective, we have adopted the presupposition of the actor as a corporality who interacts with other corporalitys (being them other actors and the audience) using as theoretical support Merleau-Ponty¿s theory and Antônio Damásio¿s studies about body and mind. As an investigative method we have proposed two different practical creation laboratories: the research on sign language applied to the scene, and the observation and analysis of the creation process of the play ¿Intersections: Harold Pinter¿s short plays¿. The objective behind those laboratories was to conduct an investigation into the actor¿s performance organicidade, taking advantage of the similarities in the essences of the concepts Spark of Life, theatrical truth and organicidade / Mestrado / Mestre em Artes

This thesis examines the use of elements of myth and ritual in the work of Peter Brook, focusing primarily on The Mahabharata ( 1986 ). The argument proposes that Brook uses myth and ritual as an integral part of his search for the culture of links .. This thesis examines the precise functioning of myth and ritual in Brook's theatre, and places his work in relation to the concepts of interculturalism and postmodernism. In so doing, The Mahabharata is seen as a valid and important step in Brook's search for the culture of links. Chapter One formulates broad-based concepts of myth and ritual, and examines their function in society and culture, as well as their role in theatre. Chapter Two offers a brief discussion of the use of elements of myth and ritual in Brook's productions, beginning with King Lear (1962), and ending with 0rghast (1971). The discussion illustrates the multiple functions which myth and ritual serve in Brook's work. Chapter Three examines the trend of interculturalism, placing Brook's work within this franlework. Attention is given to the moral and political issues implicit in interculturalism. The chapter highlights the need for intercultural theatre to be evaluated in terms of artistic criteria, rather than on anthropological or political grounds. Finally, there is a discussion of the work of other intercultural theatre practitioners. Chapter Four examines Brook's Mahabharata. A detailed discussion of the authenticity and visual presentation of Brook's interpretation shows how Brook mediates between the Indian epic and a Western audience An examination of the critical response offers insights into the dangers of insensitive cross-cultural contact.. Chapter Five offers a critical summary of the argument. Brook's search for the culture of links has led him to use elements of myths and rituals of non-Western cultures. In so doing, Brook seeks to bring their living quality to his work, and to forge links between the peoples and cultures of the world.

Stunting is widespread among brook trout Salvelinus fontinalis populations in high alpine lakes in the eastern Sierra Nevada, California. Due to their small size and poor condition, stunted brook trout are undesirable as sport fish. In the same area, a few lakes contain large brook trout. Population density was the primary difference between lakes with different sized fish. I hypothesized that in lakes with large fish the food ration per individual was sufficient and that in lakes with stunted fish the food ration was the limiting factor. I carried out removal experiments on eight brook trout populations to test the hypothesis (1) that fish size is inversely related to population density, and by that evaluate density reduction as a means of improving growth in stunted brook trout. I considered seven additional hypotheses regarding the relationships between brook trout population density and growth, fecundity, and recruitment: (2) growth response is proportional to density reduction; (3) growth response is inversely proportional to pre-reduction density; (4) growth responses of juvenile and senescent fish are less affected by density reductions than mature, reproductively active fish; (5) growth response to density reduction is inversely proportional to lake elevation; (6) fish size is proportional to angling pressure; (7) fecundity response is proportional to the reduction in population density; and (8) recruitment response is inversely related to density. I used gillnets to simultaneously remove part of the population and estimate population size through catch depletion methods that allow variable catchability. Catchability varied with lake size and with abundance, increasing as population abundance declined. Increased catchability can be explained by behavioral responses. I measured and aged 16000+ brook trout from 71 lakes, 9800+ from the eight experimental lakes. I validated annual structures on otoliths using a fluorochrome mark. For the experimental lakes, I back-calculated previous population sizes using estimates of number at age in 1989, catch at age in 1987-1988, and survival rates at age estimated from catch data collected in 1987-1989. I converted population estimates into density estimates of fish and biomass per lake surface area and volume. I tested hypothesis 1 by using survey data from 61 populations and by experimentally manipulating density in eight populations. The survey data suggested that size differences between populations of brook trout are a function of population density. Results from the eight removal experiments showed that fish size was inversely related to population density, though the increases in fish size were minor. The relationship between change in length and weight was roughly proportional to the change in density (hypothesis 2). Hypothesis 3 suggested differences in the severity of stunting in alpine lakes, and that the growth response of severely stunted populations would be more pronounced than the response of less stunted fish in lower density populations. The result was opposite; the growth response in lower density populations was greater than the response in higher density populations, suggesting that the growth response may have been proportional to the pre-reduction density. Hypothesis 4 suggested that the growth response for juvenile brook trout would be less than that for the pre-senescent adult population. The results refuted the juvenile portion of hypothesis 4: response for juveniles was greater than the response of the adults, perhaps because of greater recuperative abilities in young fish. The data supported the hypothesis that the growth response would be diminished in older fish. There was no relationship between elevation and growth response (hypothesis 5). Sport fishing had little effect on the growth of brook trout populations (hypothesis 6). Heavily fished populations were also stunted. Stunted brook trout had fecundities similar to non-stunted brook trout of the same size (hypothesis 7). Individual fecundity did increase in response to density reduction, but no more than would be expected from the increase in size. In several populations mean absolute fecundity decreased with age. Ovary weight was maintained by an apparent increase in mean egg size in older fish. The recruitment response varied between lakes (hypothesis 8). Recruitment did increase, likely in response to reduced cannibalism or competition, but I also found recruitment failure at the highest levels of density reduction. Strong cohorts were produced by increased juvenile survival rather than increased population fecundity, since population fecundity had decreased due to removal of most of the adult population. In one lake with almost no recruitment, densities remained low and fish weight doubled. For density reduction to be an effective means of increasing fish size, recruitment must be inhibited. / Science, Faculty of / Zoology, Department of / Graduate
