Fingidores em cena: a metaficção em Sérgio SantAnna e Rubens Figueiredo

A partir de uma proposta de ampliação do conceito de metaficção, a tese tem como objetivo investigar os usos metaficcionais nas obras de dois autores da literatura brasileira contemporânea: Sérgio SantAnna e Rubens Figueiredo. No caso de Sérgio SantAnna, são investigadas as relações que a metaficção estabelece com o controle do imaginário, com a reflexão estética feita no interior dos textos ficcionais e com a polêmica em torno das vanguardas. No caso de Rubens Figueiredo, a discussão sobre o uso do discurso metaficcional levará em conta os três ciclos pelos quais passa a obra do autor, ciclos esses marcados pela ênfase em determinadas questões, tais como a parodização de romances policiais, a questão da identidade e a problemática do social. O olhar panorâmico lançado para a obra ficcional dos dois autores deverá mostrar como os diferentes usos metaficcionais − ao atribuírem valores diferenciados à ligação que a literatura tem com o chamado mundo real − sinalizam duas concepções quase antagônicas do fenômeno literário

Using productivity and susceptibility indices to assess the vulnerability of United States fish stocks to overfishing

Assessing the vulnerability of stocks to fishing practices in U.S. federal waters was recently highlighted by the National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration, as an important factor to consider when 1) identifying stocks that should be managed and protected under a fishery management plan; 2) grouping data-poor stocks into relevant management complexes; and 3) developing precautionary harvest control rules. To assist the regional fishery management councils in determining vulnerability, NMFS elected to use a modified version of a productivity and susceptibility analysis (PSA) because it can be based on qualitative data, has a history of use in other fisheries, and is recommended by several organizations as a reasonable approach for evaluating risk. A number of productivity and susceptibility attributes for a stock are used in a PSA and from these attributes, index scores and measures of uncertainty are computed and graphically displayed. To demonstrate the utility of the resulting vulnerability evaluation, we evaluated six U.S. fisheries targeting 162 stocks that exhibited varying degrees of productivity and susceptibility, and for which data quality varied. Overall, the PSA was capable of differentiating the vulnerability of stocks along the gradient of susceptibility and productivity indices, although fixed thresholds separating low-, moderate-, and highly vulnerable species were not observed. The PSA can be used as a flexible tool that can incorporate regional-specific information on fishery and management activity.

Ficção fantástica: um breve olhar pelos caminhos de um objeto mutante

A presente dissertação se propõe revisitar algumas teorias escolhidas sobre a narrativa fantástica que, por sua vez, servem de referência para o estudo e a reflexão dos textos produzidos sob o signo da estranheza, da subversão do real e da inquietação humana com o desconhecido. Para tanto, selecionamos alguns teóricos que se aventuraram pelos caminhos do fantástico na busca de entender melhor e tentar definir este tipo de texto ficcional. São eles: Peter Penzoldt, Howard Lovecraft, Sigmundo Freud, Jean-Paul Sartre, Tzvedan Todorov e Filipe Furtado. O fantástico é um exemplo de construção narrativa que relativiza o real e problematiza o debate em torno dos limites do maravilhoso e sua carga simbólica, apresentando, paralelamente, a verossimilhança que a estética realista aconselha. A narrativa fantástica nasce, então, da fratura da razão que não consegue mais dar conta de uma visão de mundo que se afigura distorcida, problemática e, muitas vezes, surreal

Paul Ricoeur e a consciência como tarefa: o percurso da reflexão

Este trabalho busca principalmente reconhecer o que considera ser a dimensão sistemática do pensamento de Paul Ricoeur, fundada, como se acredita, na concepção da consciência como tarefa. Procura outrossim compreender os pressupostos ontológicos e metodológicos de seu pensamento. Pretende mostrar também que, ao perseguir uma simbólica dos sentidos múltiplos, a reflexão concreta de Ricoeur integra, a partir do que ele chama dom da linguagem, o logos filosófico, a episteme que virou ciência e a riqueza pré-filosófica do símbolo. Sua hermenêutica filosófica busca a compreensão do si, da reflexão sobre si mesmo, através da interpretação aplicada sobre os signos e símbolos de uma consciência que não se sabe no princípio, mas ao cabo do desvio de suas obras e de seus atos. A reflexão é a reapropriação daquilo que se é a partir do que é dito a si mesmo pelos signos e símbolos da cultura e das tradições. Paul Ricoeur é apresentado ainda como crítico da consciência imediata e narcísica. Ele constrói seu percurso intelectual de sorte a arbitrar o conflito das diversas interpretações que versam sobre o simbolismo humano. Este trabalho procura mostrar finalmente que o filósofo propõe de fato um novo percurso para a reflexão, através de uma démarche em dois tempos, em que o pensamento reflexivo se desapossa do imediatismo da consciência falsa e comum, para posteriormente se reapropriar das significações mais profundas manifestadas em nosso esforço para existir e nutridas pelo nosso desejo de ser. Eis a trajetória histórica e exemplar que esta dissertação busca evidenciar.

A poesia de Paul Auster

This thesis examines Paul Austers extremely neglected early work: his poetry. Five books were published: Unearth (1974), Wall writing (1976), Effigies (1977), Fragments from cold (1977) and Facing the music (1980), available only at antiquarians and restrective universities libraries in the United States, as well as at the New York Public Library. Studies around Austers poetic oeuvre are restricted to papers, reviews, translators introduction, and a thesis that focus on his poetry to produce new analyses and interpretations of Austers novelistic works. The aim of this thesis is to gather this scattered material and provide new parameters of study around his poetry. Divided into three chapters, the first one maps the literary magazines where Auster published his poems at first, the translations of his poems and critical fortune; the second examines Austers five books according to three specific topics authorship, language, I and other themes related to them; the third analyzes White Spaces, text considered by the author as the bridge that leads him to prose and in this thesis as a singular writing in which Auster consolidates his literary project, since poetry, previous to prose, yet to come. Maurice Blanchot, Karlheinz Stierle and, principally, Auster, lay the foundation of the investigation. Other theorists who contribute to the understanding of the subject will be called to build the sui generis comparativism put into effect here

Effects of land use and physicochemical water quality on grass shrimp, Palaemonetes pugio, and its parasitic isopod, Probopyrus pandalicola, in South Carolina, USA tidal creeks

Grass shrimp, Palaemonetes pugio, are a common inhabitant of US East and Gulf coast salt marshes and are a food source for recreationally and economically important fish and crustacean species. Due to the relationship of grass shrimp with their ecosystem, any significant changes in grass shrimp population may have the potential to affect the estuarine system. Land use is a crucial concern in coastal areas where increasing development impacts the surrounding estuaries and salt marshes and has made grass shrimp population studies a logical choice to investigate urbanization effects. Any impact on tidal creeks will be an impact on grass shrimp populations and their associated micro-environment whether predator, prey or parasitic symbiont. Anthropogenic stressors introduced into the grass shrimp ecosystem may even change the intensity of infections from parasitic symbionts. An ectoparasite found on P. pugio is the bopyrid isopod Probopyrus pandalicola. Little is known about factors that may affect the occurrence of this isopod in grass shrimp populations. The goal was to analyze the prevalence of P. pandalicola in grass shrimp in relation to land use classifications, water quality parameters, and grass shrimp population metrics. Eight tidal creeks in coastal South Carolina were sampled monthly over a three year period. The occurrence of P. pandalicola ranged from 1.2% to 5.7%. Analysis indicated that greater percent water and marsh coverage resulted in a higher incidence of bopyrid occurrence. Analysis also indicated that higher bopyrid incidence occurred in creeks with higher salinity, temperature, and pH but lower dissolved oxygen. The land use characteristics found to limit bopyrid incidence were limiting to grass shrimp (definitive host) populations and probably copepod (intermediate host) populations as well.

Experimental studies on the effects of toxic Microcystis aeruginosa PCC7820 on the survival and reproduction of two freshwater rotifers Brachionus calyciflorus and Brachionus rubens

Blooms of Microcystis aeruginosa frequently occur in many eutrophic lakes in China, however, there is very little experimental study on the relationship between Microcystis and rotifers from Chinese waters. The effects of different concentrations of toxic M. aeruginosa PCC7820 on two common freshwater rotifers Brachionus calyciflorus and B. rubens were investigated in laboratory experiments. B. calyciflorus was able to utilize this strain of M. aeruginosa as a food source. However, M. aeruginosa suppressed the survival and reproduction of B. calyciflorus at the highest concentration (10(6) cells/ml) probably due to the inadequate nutrition. B. rubens was inhibited by toxic M. aeruginosa PCC7820 and the inhibition increased with the increasing Microcystis concentration. Our study indicates that the two rotifers have different sensitivities to toxic M. aeruginosa and that toxic cyanobacteria may affect zooplankton community structure by differentially inhibiting the different zooplankton taxa.

Vortices in (Abelian) Chern-Simons gauge theory

The vortex solutions of various classical planar field theories with (Abelian) Chern-Simons term are reviewed. Relativistic vortices, put forward by Paul and Khare, arise when the Abelian Higgs model is augmented with the Chern-Simons term. Adding a suitable sixth-order potential and turning off the Maxwell term provides us with pure Chern-Simons theory, with both topological and non-topological self-dual vortices, as found by Hong-Kim-Pac, and by Jackiw-Lee-Weinberg. The non-relativistic limit of the latter leads to non-topological Jackiw-Pi vortices with a pure fourth-order potential. Explicit solutions are found by solving the Liouville equation. The scalar matter field can be replaced by spinors, leading to fermionic vortices. Alternatively, topological vortices in external field are constructed in the phenomenological model proposed by Zhang-Hansson-Kivelson. Non-relativistic Maxwell-Chern-Simons vortices are also studied. The Schrodinger symmetry of Jackiw-Pi vortices, as well as the construction of some time-dependent vortices, can be explained by the conformal properties of non-relativistic space-time, derived in a Kaluza-Klein-type framework.

Boundary Characterization Experiment Series Overview

Ocean acoustic propagation and reverberation in continental shelf regions is often controlled by the seabed and sea surface boundaries. A series of three multi-national and multi-disciplinary experiments was conducted between 2000-2002 to identify and measure key ocean boundary characteristics. The frequency range of interest was nominally 500-5000 Hz with the main focus on the seabed, which is generally considered as the boundary of greatest importance and least understood. Two of the experiments were conducted in the Mediterranean in the Strait of Sicily and one experiment in the North Atlantic with sites on the outer New Jersey Shelf (STRATAFORM area) and on the Scotian Shelf. Measurements included seabed reflection, seabed, surface, and biologic scattering, propagation, reverberation, and ambient noise along with supporting oceanographic, geologic, and geophysical data. This paper is primarily intended to provide an overview of the experiments and the strategies that linked the various measurements together, with detailed experiment results contained in various papers in this volume and other sources

Mixed methods feasibility study for a trial of blood pressure telemonitoring for people who have had stroke/transient ischaemic attack (TIA).

Background Good blood pressure (BP) control reduces the risk of recurrence of stroke/transient ischaemic attack (TIA). Although there is strong evidence that BP telemonitoring helps achieve good control, none of the major trials have considered the effectiveness in stroke/TIA survivors. We therefore conducted a feasibility study for a trial of BP telemonitoring for stroke/ TIA survivors with uncontrolled BP in primary care. Method Phase 1 was a pilot trial involving 55 patients stratified by stroke/TIA randomised 3:1 to BP telemonitoring for 6 months or usual care. Phase 2 was a qualitative evaluation and comprised semi-structured interviews with 16 trial participants who received telemonitoring and 3 focus groups with 23 members of stroke support groups and 7 carers. Results Overall, 125 patients (60 stroke patients, 65 TIA patients) were approached and 55 (44%) patients were randomised including 27 stroke patients and 28 TIA patients. Fifty-two participants (95%) attended the 6-month follow-up appointment, but one declined the second daytime ambulatory blood pressure monitoring (ABPM) measurement resulting in a 93% completion rate for ABPM − the proposed primary outcome measure for a full trial. Adherence to telemonitoring was good; of the 40 participants who were telemonitoring, 38 continued to provide readings throughout the 6 months. There was a mean reduction of 10.1 mmHg in systolic ABPM in the telemonitoring group compared with 3.8 mmHg in the control group, which suggested the potential for a substantial effect from telemonitoring. Our qualitative analysis found that many stroke patients were concerned about their BP and telemonitoring increased their engagement, was easy, convenient and reassuring Conclusions A full-scale trial is feasible, likely to recruit well and have good rates of compliance and follow-up.

Design thinking - a critical analysis.

The latest buzz phrase to enter the world of design research is “Design Thinking”. But is this anything new and does it really have any practical or theoretical relevance to the design world? Many sceptics believe the term has more to do with business strategy and little to do with the complex process of designing products, services and systems. Moreover, many view the term as misleading and a cheap attempt to piggyback the world of business management onto design. This paper seeks to ask is design thinking anything new? Several authors have explicitly or implicitly articulated the term “Design Thinking” before, such as Peter Rowe’s seminal book “Design Thinking” [1] first published in 1987 and Herbert Simon’s “The Sciences of the Artificial” [2] first published in 1969. In Tim Brown’s “Change by Design” [3], design thinking is thought of as a system of three overlapping spaces rather than a sequence of orderly steps namely inspiration – the problem or opportunity that motivates the search for solutions; ideation – the process of generating, developing and testing ideas; and implementation – the path that leads from the design studio, lab and factory to the market. This paper seeks to examine and critically analyse the tenets of this new design thinking manifesto set against three case studies of modern design practice. As such, the paper will compare design thinking theory with the reality of design in practice.
