Da lama à ficção: memórias e diálogos da fome nos interstícios narrativos de homens e caranguejos

Homens e caranguejos (1967), única narrativa ficcional de Josué Apolônio de Castro (1908-1973), a priori publicada em francês (1966), durante o forçoso exílio do autor em Paris, é sumariamente expressiva desde o prólogo que antecede a trama. Nomeando as páginas introdutórias deste romance como Prefácio um tanto gordo para um romance um tanto magro, Josué de Castro distende, ao retomar num tempo que já considerava anacrônico, o hábito pela escrita prefacial, a concepção de paratexto ampliada por Gerard Genette (1930), em Palimpsestes (1982). Apresentando a fome pelas recordações infantis que dela possui, o autor aguça no público-leitor a vontade de tatear, rente a seu olhar aparentemente ingênuo de criança e, de ficcionista de “primeira viagem”, o macrocosmo de memórias da fome que lhe serve como porto de partida para a criação de um microcosmo lúdico e faminto, pelo qual a imaginação e impossibilidade de re-apresentação total do vivido na linguagem, rearranjam a realidade da condição humana, reinventando-a pela articulação dramática dos elementos formais, sobretudo, tempo-espaço, narrador e personagem. A ficção se põe no ritmo fragmentado de aventuras e desventuras assumidas a partir dos intervalos da memória. Serão sumários nos estudos mnemônicos, as apreciações de Henri Bergson em Matéria e memória (1896), Jacques Le Goff em História e memória (1924) e Maurice Halbwachs, na publicação póstuma de A memória coletiva (1950), em face de serem fontes subsidiárias da aproximação entre os estudos da memória e a literatura. Lança-se mão da lembrança a fim de legendar os diálogos futuros entre o protagonista infantil, João Paulo, ávido pela liberdade sonhadora própria da criança, e as memórias de outros experientes personagens, nem tão esperançosos assim. Dá-se na narrativa o tom que oscila entre a transformação e a acomodação do eu e do outro, de espaços simbioticamente incertos e unidos por suas fomes. Fome que é, desde então, a personagem modeladora, que provoca o diálogo da presente pesquisa com o modo de apreensão que é dado por Angela Faria, na dissertação Homens e caranguejos: uma trama interdisciplinar. A literatura topofílica e telúrica (2008). Vislumbra-se no elemento famélico uma função que vai além da tematização social do subdesenvolvimento, como agente que apalpa com mãos-de-ferro o estrato formal e interno da obra.

Behavior of Montandoniola confusa Streito & Matocq (Hemiptera: Anthocoridae) preying upon gall-forming thrips Gynaikothrips ficorum Marchal (Thysanoptera: Phlaeothripidae)

The gall-forming thrips Gynaikothrips ficorum Marchal (Thysanoptera: Phlaeothripidae) is recorded in all regions where its host plant, Ficus microcarpa (Marchal) (Moraceae), has been cultivated as an urban and interior landscape plant species, including potted plants and bonsai. Similarly, the thrips predator Montandoniola confusa Streito & Matocq (Hemiptera: Anthocoridae) has generally followed the prey distribution. The gall induced by thrips degrades the plant foliage, and the thrips themselves can be annoying for people both outdoors and indoors. The galls, however, create a microcosm with all developmental stages of the thrips and its predator. In this study we present the first records of M. confusa in South America, document the species' widespread concomitant occurrence across Brazil, and report our studies of three aspects of M. confusa predation upon the eggs, larvae/prepupae, and adults of G. ficorum thrips: (i) functional response of the predator adult female as a function of different densities of thrips eggs, larvae/prepupae and adults separately: (ii) predation on eggs by adult M. confusa with adult thrips present in the gall; and (iii) adult M. confusa prey preferences when all thrips stages occurred simultaneously in the gall. For all three thrips life stages tested, the predator exhibited a type II functional response. Despite the availability of different life stages in the gall, M. confusa adults are capable of preying upon all life stages of G. ficorum, predation was preferentially on thrips eggs, with an estimated similar to 10-fold greater predation on eggs compared to larvae/prepupae and adult thrips. Egg predation was unaffected by the presence of defensive adult thrips in the gall under low densities (<30 eggs/gall) but when egg densities were greater than 30 eggs/gall, it was reduced when adult thrips were present. However, the relative number of thrips adults per gall did not statistically change the outcome. (C) 2013 Elsevier Inc. All rights reserved.

Come città dell'infanzia. Architettura, educazione e immagine in due colonie per i figli degli Italiani all'estero a Cattolica e Tirrenia

The present doctoral dissertation deals with two significant case studies of Italian holiday camps which appear as interesting architectural experiences that reflect both the pedagogic and educational programmes of the fascist regime, and the discussion on the constructive and expressive principles that characterize the Italian architecture during the Thirties. The research explains the colony "XXVIII October for the sons of the Italian workers living abroad", today known as "Le Navi" ("The Ships"), built in Cattolica in 1934 and projected by the Roman architect Clemente Busiri Vici, and the feminine colony "for the sons of the Italian workers living abroad" built in 1934 in Tirrenia and projected by the architects Mario Paniconi and Giulio Pediconi. These holiday camps are the sole buildings commissioned directly by the Department in the Italian Foreign Office with the aim of offering a seaside stay to the sons of the Italians living in the colonies who, probably, could visit Italy only one time in their life. Firstly, the work illustrates the most relevant themes concerning these holiday camps, such as the representative intents that the buildings evoked to the children attending the places. Sun-bathing and group gymnastics were some of the rituals in the communal life, where order and discipline gave a precise internal organization to the spaces. Over the correspondence to practical functions, the figures and the forms of the different spaces of the buildings involve the children in an educational dimension. Subsequently, the function of the Department in the Italian Foreign Office and the planning and constructive ideas of the two colonies will be introduced. These colonies were conceived by a precise social project with educational, welfare and therapeutic aims. The elements, the spaces and the volumes create a fixed and theatrical scene of the life, full of ideological, political and celebratory overtones. Finally, the research shows that the relation between the architectural shape of the buildings and the rituals performed by fascist tutors produces an ideal space, extraneous to the external world that could influence the behavior of the children. The plan is to transmit to the children an image of Italy that will remain engraved in their minds once they have returned to their countries. In these projects there is the intent to transmit the image of "italianity" abroad. The way to do this was to plan for them a scenery which contains all the architectural elements of Italian cities. The holiday camps are proposed a sort of microcosm that appears as an "evocation" of the places and the spaces of Italian cities. The buildings appear as veritable "cities of childhood".

Konzeptionelle Entwicklung von Mikrokosmos-Experimenten zur Untersuchung der speziesspezifischen Transformationsprozesse des Quecksilbers mittels Isotopenverhältnisbestimmungen

Zur Untersuchung der speziesspezifischen Transformationsprozesse des Quecksilbers in der Umwelt wurden erstmalig Mikrokosmosexperimente unter Verwendung von isotopenangereicherten Verbindungen durchgeführt. Es wurden naturrelevante Bedingungen simuliert, um eine spätere Übertragbarkeit der Ergebnisse auf den biogeochemischen Kreislauf des Quecksilbers zu gewährleisten. Die aufgebauten Mikrokosmen bestanden aus Boden/Pflanzen/Luft-Kompartimenten. Der Boden der Mikrokosmen wurde mit isotopenangereicherten Quecksilberspezies dotiert. Durch die Verwendung von isotopenangereicherten Verbindungen, verbunden mit gleichzeitiger ICP/MS-Detektion, konnten auftretende Transformationsprozesse beobachtet werden. Die Messung der Quecksilberspezies erfolgte mittels GC-ICP/MS nach vorheriger Derivatisierung mit Natriumtetraethylborat und Anreicherung per 'purge and trap'.Die Massenspuren der einzelnen Quecksilberisotope wurden für alle Quecksilberspezies gemessen und daraus dann für jede Spezies die Isotopenverhältnisse gebildet. Bei einer Änderung des Isotopenverhältnisses kann von einer Speziestransformation ausgegangen werden.Aus den Mikrokosmosexperimenten, denen Methylquecksilber als angereicherte Isotopenverbindung zugegeben wurde, konnte gefolgert werden, dass Methylquecksilber im Boden zunächst zu anorganischem Quecksilber demethyliert wurde. Im Anschluss daran erfolgte eine Reduktion zu elementarem Quecksilber. Dieses gebildete elementare Quecksilber verflüchtigte sich nahezu vollständig (ca. 90-100%) vom Boden in die Atmosphäre.Bei der Zugabe von anorganischem Quecksilber als angereicherte Isotopenverbindung in den Boden wurde vorwiegend eine Reduktion zu elementarem Quecksilber beobachtet, das dann in die Atmosphäre emittiert. Es konnte aber auch eine geringe Methylierung (ca. 5%) zu Methylquecksilber beobachtet werden. Daraus kann gefolgert werden, dass die methylierten Quecksilberverbindungen eine wesentliche Rolle im natürlichen Kreislauf des Quecksilbers spielen.Parallel zu den Mikrokosmosexperimenten wurden Feldversuche in einem flussnahen Feuchtgebiet, aus dem auch der Boden für die Mikrokosmosexperimente entnommen worden war, durchgeführt. In den Feldversuchen wurden Quecksilberkonzentrationen und der Quecksilberfluss zwischen dem Boden und der Atmosphäre mit Hilfe von Flusskammerexperimenten bestimmt. Es konnten mit Hilfe von Mikrokosmen, die natürliche Verhältnisse simulieren sollten, und mit Hilfe verschieden angereicherter Isotopenspikes erstmals Speziestransformationen des Quecksilbers direkt beobachtet werden. Die GC-ICP/MS-Methode ermöglichte eine eindeutige Identifikation von Edukt und Produkt der jeweiligen Umwandlung. Allerdings wurde die Untersuchung eingeschränkt durch die irreversiblen biologischen Veränderungen in den eingesetzten Mikrokosmen nach über einer Woche und durch die Notwendigkeit, vergleichsweise hohe Konzentrationen der Spikes einzusetzen, um eine statistisch signifikante Auswertung der Veränderung der Isotopenverhältnisse zu erreichen. Somit sind Mikrokosmosexperimente nur eingeschränkt für Untersuchungen des Quecksilberverhaltens geeignet.Im Rahmen dieser Arbeit ist es aber gelungen, die Mikrokosmenexperimente unter Verwendung von isotopenangereicherten Verbindungen und der GC-ICP/MS-Methode als leistungsstarkes Verfahren zur Beobachtung von Speziestransformationsprozessen des Quecksilbers zu etablieren.
