AssociaÃÃo TÃcnico-CientÃfica Eng. Paulo de Frontin / Avaliou-se a sustentabilidade da utilizaÃÃo de esgotos domÃsticos tratados na criaÃÃo do peixe ornamental molinÃsia, observando o desempenho zootÃcnico, a capacidade de adaptaÃÃo deste ao meio e o rendimento econÃmico desta modalidade de cultivo. Foram testados trÃs tratamentos: ET â abastecido com esgoto tratado; ED â abastecido com esgoto diluÃdo e Ãgua bruta em iguais proporÃÃes; AB â abastecido com Ãgua bruta. Por meio dos resultados dos parÃmetros fÃsico-quÃmicos, observou-se que o esgoto domÃstico tratado em lagoas de estabilizaÃÃo oferece condiÃÃo para se realizar o cultivo da espÃcie, somente quando diluÃdo em Ãgua bruta. Observaram-se nos tratamentos cujos tanques foram abastecidos com esgoto tratado as mesmas classes de microalgas presentes na lagoa de maturaÃÃo: Chlorophyceas, Cianophyceas, Bacillariophyceas, Zignemaphyceas e Euglenophyceas; sendo as quatro primeiras reconhecidamente aproveitÃveis como alimentaÃÃo na aquicultura. Em todos os parÃmetros de rendimento zootÃcnicos avaliados, o tratamento que utilizou o esgoto tratado diluÃdo foi o que apresentou os melhores resultados. Dentre os indicadores de bem-estar observados, apenas a avaliaÃÃo histopatolÃgica foi capaz de fornecer resultado conclusivo, o qual apontou o tratamento que utilizou esgoto tratado diluÃdo como o que proporcionou maior conforto à espÃcie cultivada. As caracterÃsticas ornamentais dos peixes cultivados nÃo sofreram influÃncia do uso do esgoto domÃstico tratado, observando-se que os padrÃes de coloraÃÃo e formato de nadadeiras nÃo foram alterados. As avaliaÃÃes, econÃmica e de sustentabilidade, tambÃm apontaram o tratamento abastecido com esgoto tratado diluÃdo como o mais apropriado. / The present work evaluated the sustainability of treated sewage reuse in the creation of ornamental molly fish, evaluating the zootechnical performance, ability to adapt to the environment and economic aspects. Three treatments were tested: ET â supplied with treated sewage; ED â supplied with sewage and raw water in the same proportion; AB â supplied with raw water. The physical-chemical results indicated that the treated sewage from stabilization ponds were adequate for the species cultivation only when diluted in raw water. The treatments that were supplied with treated sewage contained the same classes of microalgae present in the maturation pond: Chlorophyceas, Cianophyceas, Bacillariophyceas, Zignemaphyceas e Euglenophyceas; the first four classes are known to be used as feed in aquaculture. Treatment that used treated sewage diluted presented the best results in terms of zootechnical parameters. Amongst the well-being indicators, only histopathological evaluation was able to provide conclusive results, which showed that the treated sewage diluted treatment was the best in terms of comfort to the cultivated species. The ornamental characteristics of farmed fish were not influenced by the use of treated sewage, in which the patterns of color and shape of fins were not changed. The sustainability and economic evaluations also indicated the treatment with diluted treated sewage as the most appropriate treatment.

This paper evaluates the role of private policing in the patterns of violence that were prevalent in the mining regions of eastern Pennsylvania during the 1860s and 1870s, and which were attributed to an Irish secret society called the “Molly Maguires”. This topic has long been subject to academic and political controversy, and the use of agent provocateur tactics by the Pinkerton agency has been strongly suggested, but never conclusively proven. Drawing on existing research on secret societies, private policing, and the role of the agent provocateur, this paper combines two strands of research that have so far largely been discussed separately. The study then attempts to close the gap on the agent provocateur question by applying methods from criminological history. Through treating different sources as conflicting testimonies, as well as using GIS to provide new insights on crime patterns in the region, it analyzes the complex relationship between undercover policing and the groups under its surveillance. The results provide decisive new evidence regarding the agent provocateur question and the role of the Pinkerton agency during the Molly Maguire trials, as well as the character of the surviving evidence.

There are four members involved in the breeding complexes of poeciliid fishes found in the freshwaters of northeastern Mexico: males and females of a bisexual species, and diploid and triploid unisexuals. Both unisexuals reproduce by gynogenesis, i.e., an asexual type of reproduction where the sperm triggers egg development but the male genome is excluded to produce clonal offspring. The three types of females are closely related, which suggests that they are potential competitors since all three require the service of the same males. The potential for competition is compounded by a highly skewed sex ratio in favor of females. On the average the unisexuals comprise about 30% of the Poecilia females. This high frequency coupled with a close genetic relatedness to their bisexual hosts, raises the question of how the unisexuals are maintained in nature. Other investigators who work with bisexual/unisexual complexes in the related genus, Poeciliopsis, have postulated that male dominance hierarchies are responsible for restricting the access of subordinate males to their conspecific females. Consequently, these subordinate males mate with unisexual females. The current report tests whether or not this hypothesis applies to bisexual/unisexual complexes of Poecilia. We have found that linear dominance hierarchies appear to function in the defense of home ranges and do not restrict access of males to females. Dominant males exhibit less mating activity than subordinate males towards females. Previous reports showed that males are reproductively competent throughout the year, whereas females show striking asynchrony in their reproductive readiness. Such asynchrony limits the proportion of receptive females at any one time. Consequently, there are more males ready to mate than there are females receptive to their mating attempts. This may lead to mating frenzies. We postulate that these indiscriminate matings maintain the fertility of both unisexuals. When the relative reproductive outputs of adult females are compared, both unisexuals appear as fit as their bisexual congeners.

Establishing historical water velocities is a goal of Everglades restoration because of their role maintaining landscape topographic relief. However, flows may also change the trophic state of marshes by phosphorus loading. I used fatty acid (FA) and stoichiometric data to quantify how increased sheet flow altered the relative heterotrophic and autotrophic contributions to aquatic consumers in a field experiment that introduced flowing water to an Everglades marsh in November, 2014. Algal taxonomic composition was different between pre-flow and flow sampling, marked by increases in the nutrient exploiting Mougeotia species (green algae) during flow sampling. Dietary tracer FAs in consumers reflected changes in algal resources, including an increase in green algae-derived and a decrease in bacteria-derived FAs. These food web responses indicate that establishing historic water velocity in degraded wetlands can shift the origins of organic matter from a more detrital to more algal supported web.

Thesis (MA (English))--University of Stellenbosch, 2010. / Thesis presented in partial fulfilment of the requirements for the degree Master of Arts at the University of Stellenbosch / ENGLISH ABSTRACT: Since 1995, three female authors have published novels narrating the events of Vladimir Nabokov’s novel Lolita from Lolita’s point of view. What is it about the character Lolita that prompts writers to rework Nabokov’s text? In an attempt to answer this question this thesis explores reader-responses to Lolita. The grand narrative of girlhood is illuminated, and it emerges that, influenced by the discourse of Romanticism, girls’ subjectivity in the Western world is governed by an ‘innocent-or-corrupt’ dichotomy. As a result, Lolita, who seduces her stepfather, Humbert Humbert, has been vilified by readers through the decades, so that very little further critical attention has been given to her representation in the text. However, in recent years rising concern over the representation of girls has seen renewed interest in Lolita from feminist quarters, with Lolita’s non-representation being critics’ main concern. These derivative novels work towards compiling a body of feminist criticism on Lolita. A secondary function of the derivatives is the restructuring of the grand narrative of girlhood: in other words, the erasure of the ‘innocent-or-corrupt’ dichotomy in favour of a wide range of conceivable subjectivities. This is necessary because the sexualised images of girls in the media are in danger of representing girl-children as one-dimensional sexual objects. Both feminist critics and critical theorists are calling for a new form of resistance to these hegemonic media forms, so that a collaboration between the two fields seems useful. This thesis argues that the existence of the derivative novels point to the emergence of a new form of feminist resistance to the oppressive representations of advancing technological society. Consequently, the thesis performs a reading of Lolita and three derivative novels to ascertain how the girl-child is represented. Issues of interest include the Romantic discourse of childhood, the representational practices of advancing technological society, and girls’ agency. Finally, conclusions are drawn about the effectiveness of each derivative novel in terms of their contributions to both the Lolita-discourse and the feminist endeavour to restructure the grand narrative of girlhood. / AFRIKAANSE OPSOMMING: Drie vroueskrywers het sedert 1995 romans gepubliseer wat die gebeure van Vladimir Nabokov se roman Lolita uit Lolita se oogpunt oorvertel. Wat is dit omtrent die karakter Lolita wat skrywers aanspoor om Nabokov se teks te hersien? In ‘n poging om hierdie vraag te beantwoord verken hierdie tesis leser-reaksies op Lolita. Die meesternarratief oor jongmeisieskap word blootgelê en dit kom na vore dat meisies se subjektiwiteit in die Westerse wêreld, onder die invloed van die Romantiese diskoers, regeer word deur die digotomie van ‘onskuldig-of-korrup’. Gevolglik is Lolita, wat haar stiefpa, Humbert Humbert, verlei, oor die dekades heen deur lesers sleggemaak, sodat baie min kritiese aandag verder aan haar gewy is. Toenemende kommer onder feministe rondom die uitbeelding van meisies het egter in die afgelope klompie jare tot hernieude belangstelling in Lolita gelei, met die gebrek aan aandag aan Lolita se uitbeelding as hoofbekommernis. Die Lolita-verwerkings dra by tot die saamstel van ‘n versameling van feministiese kritiek oor Nabokov se teks. Die sekondêre funksie van die verwerkings is die herstrukturering van die meesternarratief aangaande jongmeisieskap: met ander woorde, die uitwissing van die onskuldig-ofkorrup digotomie ten gunste van ‘n wye reeks denkbare subjektiwiteite. Dít is nodig omdat die geseksualiseerde beelde van meisies wat in die media voorkom, die gevaar loop om meisies as een-dimensionele seksobjekte uit te beeld. Beide feministe en kritiese teoretici beywer hul vir ‘n nuwe vorm van teenstand teen hierdie verdrukkende uitbeeldings, so samewerking tussen die twee is nuttig. Hierdie tesis doen dit aan die hand dat die bestaan van Lolita-verkwerkings bewys is van die ontluiking van ‘n nuwe vorm van feministiese teenstand teen die verdrukkende uitbeeldings van die vooruitgaande tegnologiese samelewing. Gevolglik analiseer hierdie tesis Lolita en drie verwerkings om vas te stel hoe die meisiekind uitgebeeld word. Sake van belang sluit die Romantiese diskoers van kindwees, die uitbeeldingspraktyke van die toenemend tegnologiese samelewing, en meisies as agente in. Uiteindlik word gevolgtrekkings gemaak oor die effektiwiteit van elke roman ten opsigte van hul bydraes tot beide die Lolita-diskoers en die feministiese poging om die meesternarratief aangaande jongmeisieskap te herstruktureer.

My dissertation offers a new look at how women authors used popular genres to negotiate their economic, artistic, and sexual autonomy, as well as their national and imperial identities, in the context of the changes brought by modernity. As medical science and popular media attempted to delineate women’s sexual natures, Sylvia Townsend Warner, Winifred Holtby, Kate O’Brien, and Molly Keane created narratives which challenged not only psychoanalytic proscriptions about the need for sexual satisfaction, but traditional ideas about women’s inherent modesty. They absorbed, revised, and occasionally rejected outright the discourses of sexology in order to advocate a more diffuse sensuality; for these writers, adventure, travel, independence, creativity, and love between women provided satisfactions as rich as those ascribed to normative heterosexuality. I identify a history of queer sexuality in both Irish and English contexts, one which does not conform to emergent lesbian identity while still exceeding the limits of heteronormativity. / text

My dissertation challenges the longstanding dismissal of love in James Joyce's texts by examining the ethical and political implications of his love stories. Primarily using Martin Buber's works (but also including perspectives derived from bell hooks and Julia Kristeva), I define love as an affirmation of otherness and adopt a critical framework that promotes the love of others over the narcissistic devotion to oneself. In so doing, I highlight love as the ultimate challenge to authoritarian systems because the embrace of the other is necessary to transcend the boundaries that alienate individuals from each other and that justify imperialist and racist political structures. I thus offer a love ethic that not only compels meaningful individual interaction, but also establishes a model for effective social and civic participation, encouraging a climate of cooperation that embraces the solidarity and empathy needed for progressive politics. I also argue that analyzing Joyce's works provides a fruitful opportunity to recognize the individual and political viability of this love ethic. Focusing on Dubliners, Stephen Hero, A Portrait of the Artist as a Young Man, Exiles, and Ulysses, I examine the relationships between his characters' pursuits of love and their socio-political struggles, arguing that their love for others directly influences their acceptance of otherness within the colonialist discourses of Joyce's Dublin. For example, James Duffy's refusal of Emily Sinico in "A Painful Case" also rejects her advice to engage in the political cooperation that would promote his socialist ideas. Similarly, Stephen Dedalus's promotion of symbolic romance over real-world attachments focuses his aesthetics on ideal beauty instead of everyday Dublin, which alienates him from his audience and limits the practical success of his art. By contrast, Leopold Bloom's love for his wife Molly reflects a broader empathy for others that encourages social dialogue and counteracts what Joyce called "the old pap of racial hatred," an element in both British imperialism and Irish nationalism. My dissertation's afterword anticipates the amorous potential of Finnegans Wake, reading ALP's concluding soliloquy as a demonstration of her enduring affection for HCE that is reignited through each iteration of the text's cyclical narrative.
