Models of complexity in Robert Coover's John's wife and the adventures of Lucky Pierre

This doctoral dissertation analyzes two novels by the American novelist Robert Coover as examples of hypertextual writing on the book bound page, as tokens of hyperfiction. The complexity displayed in the novels, John's Wife and The Adventures of Lucky Pierre, integrates the cultural elements that characterize the contemporary condition of capitalism and technologized practices that have fostered a different subjectivity evidenced in hypertextual writing and reading, the posthuman subjectivity. The models that account for the complexity of each novel are drawn from the concept of strange attractors in Chaos Theory and from the concept of rhizome in Nomadology. The transformations the characters undergo in the degree of their corporeality sets the plane on which to discuss turbulence and posthumanity. The notions of dynamic patterns and strange attractors, along with the concept of the Body without Organs and Rhizome are interpreted, leading to the revision of narratology and to analytical categories appropriate to the study of the novels. The reading exercised throughout this dissertation enacts Daniel Punday's corporeal reading. The changes in the characters' degree of materiality are associated with the stages of order, turbulence and chaos in the story, bearing on the constitution of subjectivity within and along the reading process. Coover's inscription of planes of consistency to counter linearity and accommodate hypertextual features to the paper supported narratives describes the characters' trajectory as rhizomatic. The study led to the conclusion that narrative today stands more as a regime in a rhizomatic relation with other regimes in cultural practice than as an exclusively literary form and genre. Besides this, posthuman subjectivity emerges as class identity, holding hypertextual novels as their literary form of choice.

O grau zero da organização: diálogos entre Deleuze e Robert Cooper

O objetivo do presente trabalho é reconstituir o conceito de grau zero da organização formulado por Robert Cooper a partir de um diálogo entre os escritos desse autor e a filosofia de Gilles Deleuze. Para alcançar este objetivo, primeiramente explicitaremos nosso compromisso epistemológico com o pós-estruturalismo, buscando situar este fenômeno do pensamento em termos de seu posicionamento nos estudos organizacionais. Nesta seção teremos o primeiro contato com o pensamento de Deleuze e Robert Cooper e, de antemão, apresentaremos a noção de grau zero como um conceito capaz de levantar possíveis pontos de convergência/divergência presentes nos trabalhos destes autores bem como de suscitar uma problematização do conceito de organização em seu nível ontológico e a própria ruptura do pós-estruturalismo com o estruturalismo no âmbito do estudo das organizações. Na segunda parte do trabalho analisaremos os escritos de Robert Cooper buscando realizar um apanhado geral de sua obra (que tratou do tema da organização), situaremos o conceito de grau zero da organização na mesma justificando sua escolha como o ponto de partida para o diálogo que buscaremos traçar entre Cooper e Deleuze. Após isso, faremos uma leitura ampla da filosofia deleuzeana e buscaremos compreender alguns de seus elementos fundamentais para, então, aproximar o pensamento de ambos os autores e desenhar possíveis aproximações e/ou afastamento. Foi possível identificar aproximações entre os pensamentos de Deleuze e Cooper: por um lado, destacamos que a primazia do devir, a proposta de um pensamento aberto e plural, uma preocupação com a linguagem e com materialidades, bem como fortes traços de influências vindas do estruturalismo e da psicanálise são pontos de aproximação marcantes entre os pensamentos destes autores. Por outro lado, também destacamos alguns possíveis pontos de divergência: a crítica à representação enquanto instância de limitação/negação; diferentes concepções de inconsciente (o inconsciente freudiano em Cooper/forjamento de noção própria do inconsciente em Deleuze); e, finalmente, no engajamento político da visão crítica proposta por seus trabalhos. Destacamos, finalmente, que a noção de grau zero da organização de Cooper ainda é passível de questionamentos quando deparada com a crítica ao estruturalismo e à representação conforme presente na filosofia de Deleuze. Concluímos que a filosofia de Deleuze impõe a necessidade reconstituir este conceito de forma a fazer com que ele afaste-se da possibilidade de ser tomado como uma visão estruturalista (uma esfera meramente linguística) e/ou oposicional (o grau zero enquanto mera desorganização) da organização.

Contra as Secas: a engenharia e as origens de um planejamento regional no nordeste brasileiro

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

Efeito da densidade de ninfas de Aphis gossypii Glover, 1877 (Hemiptera, Aphididae) no consumo alimentar e aspectos biológicos de Orius insidiosus (Say, 1832) (Hemiptera, Anthocoridae)

Orius insidiosus (SAY, 1832) is an important predator for biological pest control programs. The objective of this work was to evaluate the functional response, predation capacity and reproductive aspects of O. insidiosus when predating 1, 5, 10, 15, and 20 third/fourth instar nymphs of Aphis gossypii. The tests were conducted under laboratory conditions. Females of the predator were individually maintained in Petri dishes with a cotton leaf at each one of the aphid densities. The average rate of predation was of 0.93 [plus or minus] 0.13, 3.58 [plus or minus] 0.80, 7.31 [plus or minus] 1.45, 7.40 [plus or minus] 1.16, and 10.54 [plus or minus] 1.84 at the densities of 1, 5, 10, 15, and 20 aphids, respectively. The results showed an attack rate of 0.10 h-1 and 1.82 h of manipulation time. The predator spent 3.10 to 4.08 h feeding on leaf cotton glands; this behavior was not directly influenced by the prey density. The proportion of egg laying per female grew up to the density of 10 nymphs whereas the number of eggs per laying increased with the number of available preys.

Efeito de cultivares de algodoeiro sobre a biologia e capacidade predatória de Orius Insidiosus (say, 1832) (hemiptera: anthocoridae) predando Aphis Gossypii Glover, 1877 (Hemiptera: Aphididae)

The objective of this research was to determine the survival, reproduction and predaceous capacity of Orius insidiosus on cotton aphid Aphis gossypii. Cotton plants of Antares, CNPA7H and Acala 90 cultivars (respectively, without tricome, medium tricome density and high tricome density) were individualized and infested with 15 third/fourth instar nymphs of A. gossypii, and then first-instar nymphs of O. insidiosus were released on the plants. The evaluations were made daily, quantifying survival and nymphal development; the number of cotton aphids A. gossypii per day and total; the number of eggs and the population of the predator (number of insects by female); and the conversion efficiency of A. gossypii predaceous. The nymphal development did not differ according to the cotton cultivars. The Antares cultivar favored a higher daily predation rate for the 1st, 2nd and 4th instars and adults of O. insidiosus. The number of eggs and nymphs was smaller when O. insidiosus females were confined on the Acala 90 cultivar. According to the predation rate of O. insidiosus, the efficiency of alimentary conversion was determined for the Antares, CNPA7H and Acala 90 cultivars, being respectively, 4.28, 3.00 and 2.75 cotton aphid predation for each egg of the predator.

Tabelas de vida de Orius insidiosus (Say, 1832) (Hemiptera: Anthocoridae) predando Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) em diferentes cultivares de algodoeiro

The life table parameters were studied for Orius insidiosus on the three cotton plant cultivars Antares, CNPA7H and Acala 90 (respectively, without tricome, medium tricome density and high tricome density). This study showed that the type of cultivar can strongly influence the life-table parameters. The intrinsic rate (rm) was 0.088 (on Antares), 0.081 (CNPA7H) and 0.079 (on Acala 90), which was expected as these differences were also observed for development time, survival, fecundity and longevity on the cultivars. The reproductive rate (Ro) was 18.53 on the Antares cultivar, but showed less difference for CNPA7H (12.26) and Acala 90 (12.95). The development time was 33.9, 30.62 and 32.13 days for Antares, CNPA7H and Acala 90, respectively. The age-specific survival was similar until the 12th day. Maximum survival was 60 days on the Antares cultivar. Females usually began to oviposit after 16 days on the Antares cultivar and the after 19 days day on CNPA7H and Acala 90.
