O objetivo do presente trabalho foi estudar a biologia e elaborar a tabela de vida de fertilidade de Diaphorina citri (Kuwayama, 1908) (Hemiptera: Liviidae) em duas espécies de Murraya [Murraya paniculata (L.) Jack e Murraya koenigii (L.) Sprengel] e estudar a biologia de Tamarixia radiata Waterston, 1922 (Hymenoptera: Eulophidae) em psilídeos provenientes das duas espécies de Murraya citadas, visando fornecer subsídios ao controle da praga em programas de MIP. Foram realizados experimentos em confinamento (sem chance de escolha) para avaliar o efeito de duas espécies de Murraya sobre a alimentação e fertilidade de D. citri, bem como a biologia da referida espécie de psilídeo nos dois hospedeiros. Também foi avaliado o efeito do hospedeiro no parasitismo sobre D. citri e na biologia de T. radiata. Pode-se concluir que: D. citri preferiu se alimentar em M. koenigii, porém para a oviposição o hospedeiro preferido foi M. paniculata. No entanto, os demais parâmetros observados indicaram que M. paniculata é o hospedeiro mais adequado para o desenvolvimento do psilídeo. Com base na tabela de vida de fertilidade, a taxa liquida de reprodução (R0), de D. citri, foi 3,1 vezes maior quando criado em M. paniculata; os demais parâmetros, exceto o tempo médio de cada geração (T), também favoreceram o desenvolvimento do inseto quando criado em M. paniculata. O desenvolvimento e parasitismo de T. radiata sobre ninfas de D. citri foram afetados quando criadas nas duas espécies, sendo observados melhores resultados quando os psilídeos foram criados em M. koenigii em testes de confinamento. Os resultados obtidos poderão fornecer subsídios ao controle e manejo do psilídeo transmissor do HLB.The aim of the present research was to evaluate the biology and fertility life table of Diaphorina citri (Kuwayama, 1908) (Hemiptera: Liviidae) comparatives in the two species of Murraya [Murraya paniculata (L.) Jack e Murraya koenigii (L.) Sprengel], and to evaluate the biology of Tamarixia radiata Waterston, 1922 (Hymenoptera: Eulophidae) in the two species studied in confinement, aiming to provide subsidies for pest control in Integrated Pest Management (IPM). Experiments were carried out in confinement (no choice) to evaluate the effect of the two species of Murraya on the feeding and fertility of D. citri, as well as the biology of Asian Citrus Psyllid (ACP) in two hosts. Biology and the effect of host on parasitism of T. radiata on nymphs of D. citri was evaluated. It can be concluded that: D. citri preferred to feed on Murraya koenigii (L.) Sprengel, but for oviposition the preferred host was Murraya paniculata (L.) Jack. However, the other parameters observed indicate that M. paniculata is the most suitable host for the development of the psyllid. According to the fertility life table, the reproduction net rate (R0) of D. citri was 3.1 times higher if reared on M. paniculata; the other parameters, except the mean time of each generation (T), also supported results when it was reared on M. paniculata. The development and parasitism of T. radiata on nymphs of D. citri were affected when reared on different hosts, and better results were observed when T. radiata reared on M. koenigii. The results obtained may provide subsidies for the control and management of the HLB.

Previous issue date: 2007-12-11The plant Murraya paniculata is native in Asia where its root barks have produced the contraceptive and hormonal alkaloid yuehchukene. In Brazilian specimens no alkaloid was detected. This had inspired new researches about the microorganisms that interact with it in Brazil, including the present work. Therefore, 1711 endophytic microorganisms were isolated from four host plants, in São Paulo State, and the seasonal colonization indexes, the microbial frequencies and the specificities of the identified groups per tissues (microhabitats) were verified. Among the obtained endophytes, 1061 were filamentous fungi and 650 were bacteria, with 62% and 38% of frequency and 33% and 20% of colonization index, respectively. The colonization indexes of the bacteria in comparison to the of fungi were lower in all gatherings and hosts, principally for leaves that, had shown the bigger frequency for the fungi and the smaller for the bacteria. Fungi were clustered in 20 morphological groups, 15 identified to genus level and five unknown, including two Mycelia sterilia. The recognized genera were Fusarium, Colletotrichum and its teleomorphs Giberella and Glomerella respectively, Trichoderma, Phomopsis, Paecilomyces, Penicillium, Aspergillus, Epicoccum, Pestalotiopsis, Alternaria, Xylaria, Nigrospora and Guignardia and the unknown were named A-E groups. The more frequent genera were rich in diversity, according to morphological and molecular data. A more diversity of fungi genera were verified in the winter (17) and a less in the spring (9) as the endophytic fungi were smaller in quantity in the summer (44.7%) and greater in the autumn (77.7%). From a sample of 59 isolates and six fungi as prototypes genomic DNAs were obtained and their ITS-1 regions were sequenced. The unknown strain B (Fed) had sequenced its 5.8s and ITS-2 regions. 21 species were identified by their ITS-1 regions and two others were hypothesized as novelty: one Trichoderma and the Fed that all morphological and chemotaxonomic studies appoint as a new species. Trichoderma associated to M. paniculata were in majority from barks and had showed great diversity of species (9). It was evaluated too the potential of the endophytes from host for bioactive metabolite production. The more promising groups for extracellular substances were the fungi Penicillium, with bactericidal and antiprotozoal actions, Pestalotiopsis, active against Candida, and Trichoderma, with fungicidal and bactericidal activities. For Fed it was noted its intracellular metabolites as strong bactericidal and its volatiles as anti-fungi. By looking for the active principles of those microorganisms, from Penicillium citrinum the citrinin and an undetermined alkaloid were obtained and from Trichoderma koningii 13 metabolites, including four koninginins related to those biological activities observed were identified. From Fed-3, 10 substances were obtained, seven fixed and three volatile, including a novel manosil guaiane type sesquiterpene and the new, as natural substances, 3-Hydroxy-5-phenylmethyl- (3S,5R)-b10-O-tetrahydrofuran-2-one and chloroacetonitrile. The chloroacetonitrile was suggested as the active principle of the Fed s volatiles. This work was important to reveal the diversity of the endophytes from Brasilian M. paniculata, the high variability of their more frequent genera, two possible novel species and the potential of them to produce bioactive and new metabolites. This work is hoped to contribute for understanding the endophytic microorganism biodiversity as well as their chemical and biotechnological potential.
A planta Murraya paniculata é de origem asiática e em seu continente de origem foi isolado, das cascas das raízes, o alcalóide yuehchukeno que apresenta atividade anticoncepcional e hormonal. Em espécimes brasileiros nenhum alcalóide foi detectado, o que inspirou novas pesquisas envolvendo o estudo dos microrganismos que interagem com esta, incluindo o presente trabalho. Assim, foram isolados 1.711 microrganismos endofíticos de quatro hospedeiras, no estado de São Paulo, verificando-se os índices de colonização sazonal, a freqüência e a especificidade dos grupos identificados por tecidos (micro-habitat). Dos isolados, 1.061 eram fungos filamentosos e 650 eram bactérias, com freqüências de 62% e 38% e índices de colonização de 33% e 20%, respectivamente. Os menores índices de colonização foram observados para as bactérias em todas as coletas, principalmente nas folhas que apresentaram a maior freqüência para os fungos. Os fungos endofíticos foram classificados em 20 grupos morfológicos, 15 identificados ao nível de gênero e cinco desconhecidos, sendo dois Micelia sterilia. Os gêneros identificados foram Fusarium, Colletotrichum e seus telemorfos Giberella e Glomerella rescpectivamente, Trichoderma, Phomopsis, Paecilomyces, Penicillium, Aspergillus, Epicoccum, Pestalotiopsis, Alternaria, Xylaria, Nigrospora e Guignardia e os não identificados foram denominados como grupos A-E. Foi também detectada grande diversidade dentro dos gêneros mais freqüentes, pela morfologia e por marcadores moleculares. Foi verificada maior diversidade de gêneros de fungos no inverno (17) que na primavera (9). A população de fungos endofíticos foi menor no verão (44,7%) em contraste com o outono (77,7%). De uma amostragem de 59 isolados e seis controles foram extraídos os DNAs genômicos e seqüenciadas as regiões ITS-1. Para a linhagem indeterminada B (Fed) foi sequenciada a região 5,8s e a ITS-2. Foram identificadas 21 espécies pela região ITS-1 e detectadas duas possíveis espécies novas: uma de Trichoderma e o Fed cujos estudos morfológicos e quimiotaxonômicos apóiam esta hipótese. Os Trichoderma associados a M. paniculata foram isolados principalmente das cascas e apresentaram 9 espécies, sendo uma indeterminada. Foi também avaliado o potencial para produção de substâncias bioativas de endófitos. Os grupos mais promissores para a produção de substâncias extracelulares foram os dos fungos Penicillium com ação bactericida e anti-protozoária, Pestalotiopsis candicida e Trichoderma fungicida e bactericida. Fed com substâncias intracelulares de forte ação bactericida e de voláteis fungicidas. Buscou-se ainda o isolamento dos princípios ativos tendo sido isolados de Penicillium citrinum a citrinina e um alcalóide indeterminado, de Trichoderma koningii 13 substâncias, das quais quatro koningininas relacionadas às atividades biológicas detectadas. De Fed-3 foram identificadas 10 substâncias, sete fixas e três voláteis, incluindo um sesquiterpeno guaiano manosilado inédito e as substâncias 3-Hidróxi- 5-fenilmetil-(3S,5R)-b10-O-tetrahidrofuran-2-ona e cloroacetonitrila, isoladas pela primeira vez de fonte natural. A esta última é sugerida a ação fungicida dos voláteis. Esta pesquisa foi oportuna ao revelar a diversidade de microrganismos associados à hospedeira, a alta variabilidade entre e dentre os gêneros, incluindo duas possíveis novas espécies, e o potencial na produção de moléculas bioativas e inéditas. Espera-se ter contribuído para o conhecimento da biodiversidade dos microrganismos endofíticos e do potencial químico e biotecnológicos que eles representam.

Full textAbstract:
Atualmente, o controle da doença Huanglongbing (HLB) ou greening é baseado, principalmente, no controle químico do inseto vetor Diaphorina citri, realizado por meio de aplicações intensivas de produtos químicos, o que vem causando surtos de pragas secundárias, ressurgência de pragas, seleção de população resistente e eliminação dos inimigos naturais. Com esse trabalho, objetivou-se avaliar a possibilidade da utilização da planta de curry (Murraya koenigii) como planta-isca para o manejo do psilídeo D. citri. Para isso, foram realizados os seguintes testes: i) teste de transmissão de \'Candidatus Liberibacter asiaticus\' para determinar se a planta de curry não é hospedeira da bactéria; ii) teste de comportamento de escolha, para verificar a preferência hospedeira de D. citri em plantas de curry em relação a citros; iii) teste de comportamento alimentar do psilídeo por meio da técnica de Electrical Penetration Graphs (EPG) em plantas de curry, visando entender a alimentação do inseto nessa planta; iv) seleção de inseticidas sistêmicos para uso em plantas de curry, determinando o período residual e eficiência; e v) teste com plantio-isca em um talhão de citros, no qual foram instaladas plantas de curry em frente as plantas de citros e o psilídeo foi monitorado com o uso de armadilhas adesivas amarelas. Como resultado, observouse que a planta de curry não é hospedeira da bactéria \'Ca. L. asiaticus\' por meio da inoculação pelo psilídeo D. citri, e, em teste de livre escolha e de olfatômetro, é mais atrativa para o psilídeo do que a planta de citros, em condições laboratoriais. O comportamento alimentar do psilídeo em plantas de curry é diferente do que em citros e murta, sendo que o consumo da seiva do xilema em plantas de curry é maior. Além disso, inseticidas aplicados via \'drench\', como thiamethoxam e imidacloprid, nessa planta, são eficientes contra D. citri, pois controlam o psilídeo adulto por mais de 70 dias após a aplicação e, no campo, a captura de espécimes nas parcelas com a planta de curry foi maior, podendo concluir, portanto, que a planta de curry M. koenigii apresenta potencial para ser utilizada como plantio isca para manejo do psilídeo D. citri e, consequentemente, da doença HLB.Currently, the control of the disease Huanglongbing (HLB) or greening is based mainly on the chemical control of the insect vector Diaphorina citri, through intensive applications of insecticides, which has been causing secondary pest outbreaks, pest resurgence, selection of population resistant and elimination of natural enemies. The goal of this work was to evaluate the possibility of using the curry leaf (Murraya koenigii) as a trap crop for the management of the D. citri. For this, the following tests have been performed: i) Transmission test of \'Candidatus Liberibacter asiaticus\' to determine if the curry leaf is not a host for the bacterium; ii) test of choice behavior, to verify the host preference of D. citri to curry leaves in relation to citrus plants; iii) test of probing behavior in curry leaf using the Electrical Penetration Graphs (EPG) technique, in order to understand the feeding of the insect on this plant; iv) selection of systemic insecticides for use in curry leaf, determining the residual period and efficiency; and v) test with trap crop in a citrus orchard, in which curry plants were installed in front of the citrus plants and the psyllid was monitored with the yellow stick traps. As a result, it has been observed that the curry leaf is not a host to \'Ca. L. asiaticus\' by the D. citri inoculation and, in a free choice and olfactometer test, is more attractive to the psyllid than the citrus plant under laboratory conditions. The probing behavior of the psyllid in curry leaf is different from citrus and orange jasmine, being the ingestion of xylem sap in curry leaf higher. In addition, the insecticides applied by \'drench\' such as thiamethoxam and imidacloprid in these plants are efficient against D. citri for more than 70 days after application and, in the field, the capture of psyllids in the plots with the curry leaf was higher and could therefore conclude that, the curry leaf M. koenigii is a potencial plant to be used as a trap crop for the management of D. citri and consequently, the disease HLB.

The Penicillium sp. A, Penicillium sp. B (M. paniculata) and P. herquei (M. azedarach) fungus were grown in liquid media (Czapeck s) and also in solid media (rice). After the inoculation of the fungus, their grownth were interrupted by adition of methanol. The extracts of the biomass were obtained by several maceration technics using organic solvents. The crude extracts were fractionated by liquid-liquid partition and also several chromatography technics. The pure compounds were obtained by refractionation of previous fractions by column chromatography, thin layer chromatography and HPLC. The structures of the compounds were elucidated by several spectroscopic technics as NMR, MS and IR. Several classes of compounds were isolated as nucleosides, esteroids, carbohydrates, polyketides among many others. Antimicrobial assays were carried out with purified compounds, where the polyketides citrinine, citrinine-D, citrinine H1, emodine, citreoroseine and janthinone showed promising results. Leishmanicidal assays were also carried out using emodine, citreoroseine and janthionone, where only the former showed a reasonable activity. The fragmentation by MS and also the biogenesis proposal of some isolated compounds are discussed in the present work.
Os fungos Penicillium sp A, Penicillium sp B (M. paniculata) e P. herquei (M. azedarach) foram cultivados em meios de cultura líquido (Czapeck s) e meio sólido (Arroz) para crescimento das colônias. Após o período de cultivo os crescimentos dos fungos foram interrompidos com metanol, posteriormente foram obtidos os extratos das biomassas produzidas utilizando-se técnicas de maceração com solventes orgânicos. Os extratos brutos foram fracionados através de partições liquido-liquido e cromatografia em coluna a vácuo. As frações obtidas foram então refracionadas utilizando-se cromatografia em coluna, cromatografia em camada delgada preparativa e HPLC para isolamento dos constituintes químicos. As substâncias tiveram as suas estruturas elucidadas através da utilização de técnicas espectrométricas de RMN, EM e IV. Onde foram isoladas substâncias das classes dos nucleosideos, esteróides, carboidratos, policetídeos, entre outras. Foram realizados ensaios antimicrobianos com as substâncias puras, sendo que os policetídeos citrinina, citrinina-D, citrinina H1, emodina, citreoroseina e janthinona apresentaram bons resultados. Realizaram-se, ainda, ensaios leishmanicidas com as substâncias emodina, citreoroseina e janthinona, somente a primeira apresentou atividade considerável. As propostas de fragmentação por massas e de biogênese de alguns constituintes químicos são discutidas no trabalho.

Orientador: André Gonzaga dos SantosResumo: Murraya paniculata L. Jack (Rutaceae) é uma árvore amplamente utilizada nas Américas como ornamental. Porém, esta espécie vegetal nativa da Índia é considerada medicinal na Ásia e reconhecida pelas propriedades adstringentes, estimulantes, analgésicas e anti-inflamatórias. Diversos estudos revelam a presença de alcaloides, flavonoides, cumarinas e componentes do óleo essencial, fundamentalmente, e as propriedades antibacterianas, antifúngicas, anti-inflamatórias e analgésicas foram observadas para extratos de M. paniculata. Fitoterápicos derivados da planta estão disponíveis no Sistema Nacional de Saúde cubano, como anti-inflamatórios, porém é limitado o conhecimento dos metabólitos secundários majoritários da espécie coletada em Cuba e sua relação com a atividade farmacológica. Neste contexto, foi desenvolvido este trabalho que teve como objetivo realizar o estudo químico do extrato etanólico de folhas de M. paniculata, a fim de contribuir com sua padronização e com o estabelecimento de especificações de qualidade com base na composição química e atividade anti-inflamatória. O fracionamento do extrato etanólico foi iniciado por extração em fase sólida fornecendo 4 frações. A fração EFSMp4 foi fracionada utilizando-se cromatografia em coluna. A purificação final das substâncias majoritárias obtidas a partir de EFSMp4 foi realizada por cromatografia líquida de alta eficiência preparativa de fase reversa.

Full textAbstract:
A arborização urbana oferece diversos benefícios para a população, e sua necessidade vem aumentando com o crescimento das cidades. Mas como qualquer outro equipamento urbano, existe custo de implantação, manutenção e, também, prejuízos. Dentre os potenciais prejuízos da arborização urbana, estão os danos em calçamentos e estruturas de construção civil. Este trabalho objetivou identificar quais os parâmetros que influenciam esses danos e, auxiliar na definição de políticas públicas para a arborização urbana. O estudo baseou-se no Inventário da Arborização Urbana do Município de Piracicaba, em 15 bairros. Para todo o inventário, foram identificadas as unidades e profundidades do solo baseado no Levantamento Pedológico Semidetalhado do Município de Piracicaba. Optou-se por utilizar, para análise das trincas na calçada, uma espécie arbórea, a sibipiruna (Caesalpinia pluviosa Dc.) e, uma arbustiva, a falsa-murta (Murraya paniculata (L.) Jacq.), pois existe um conceito amplamente difundido, de que, as espécies arbustivas, não causam danos ao calçamento; já, as arbóreas, são conhecidas por danificar as calçadas. Na coleta de campo, avaliou-se os seguintes itens: endereço, espécie, árvore suprimida ou substituída, CAP, tamanho do canteiro, colo pavimentado, poda da parte aérea, estrutura urbana danificada, condições da calçada e material do piso. O índice de supressão da falsa-murta foi igual ao da sibipiruna (1,7%), sendo que 89,2% das falsamurtas e 92,6% das sibipirunas não foram substituídas por outra espécie. Para a falsamurta, a concentração de indivíduos, se deu na faixa de CAP de 21 a 80 cm (82,9%); 70,2% apresentaram trincas na calçada e 29,8% ausência de trincas; 44,6% dos indivíduos tinham canteiro de até 0,20 m2; 92,3% dos indivíduos sofreram poda considerada ruim e 75,1% dos indivíduos estavam em calçada de cimento. Para a sibipiruna, a concentração de indivíduos se deu na faixa de CAP de 101 a 160 cm (57,0%); 99,4% apresentaram trincas na calçada e 0,6% ausência de trincas; 44,6% dos indivíduos estavam plantados em locais classificados como canteiros indefinidos; 94,6% dos indivíduos sofreram poda considerada ruim e a calçada mais comum foi a de cimento com 63,1% de indivíduos. A profundidade do solo não teve influência em causar ou não trincas nas duas espécies. Com a análise estatística (teste Quiquadrado) pôde-se contrapor alguns conceitos difundidos na arborização urbana, concluindo-se que os arbustos também causam danos e as podas influenciam nos danos em calçadas, entre outras. Não existe solução simples para eliminação do conflito entre as árvores viárias e os equipamentos e estruturas urbanas. A população precisa e deve ser informada sobre todos os parâmetros, opções, benefícios e prejuízos de cada ação que estimule ou iniba o plantio de uma árvore em calçada.The urban forestry offers several benefits for the population and their need is increasing with the growth of cities. But like other urban equipment, there is cost of implementation, maintenance, and also losses. Among the potential damage of urban forestry, are paving the damage to structures and construction. This study aimed to identify the parameters that influence the damage and assist in the definition of public policies for urban forestry. The study was based on an inventory of urban forestry of the city of Piracicaba, in 15 districts. For the entire inventory, the units were identified and depths based on soil survey Pedológica semidetailed the city of Piracicaba. Was used for analysis of cracks in the sidewalk, a tree species, the sibipiruna (Caesalpinia rainy Dc.), And a bush, the falsa-murta (Murraya paniculata (L.) Jacq.), There is a concept widely widespread, that the shrub species, do not cause damage to the paving, while the trees are known to damage the sidewalks. In collecting field and focuses on the following: address, sort, tree removed or replaced, CAP, bed size, lap paved, pruning of shoots, damaged urban structure, and material conditions of the pavement of the floor. The rate of elimination of falsa-murta was equal to the sibipiruna (1.7%), whereas 89.2% of falsa-murta and 92.6% of sibipiruna were not replaced by other species. For the falsemyrtle, the concentration of individuals, was in the range of CAP 21 to 80 cm (82.9%), 70.2% had cracks in the sidewalk and 29.8% no broken; 44.6% of individuals had bed tree to 0.20 m2, 92.3% of individuals have suffered as bad pruning and 75.1% of individuals were in sidewalk cement. For sibipiruna, the concentration of individuals was in the range of 101 to 160 CAP cm (57.0%), 99.4% had cracks in the sidewalk and 0.6% absence of cracks, 44.6% of individuals were planted in locations classified as uncertain beds trees, 94.6% of individuals have suffered as bad pruning and sidewalk was the most common cement with 63.1% of individuals. The depth of soil had no influence on whether or not cause cracks in the two species. With the statistical analysis (Chi-square) could be countered some concepts available in urban forestry, concluding that the damage also shrubs and pruning influence the damage to sidewalks, among others. There is no simple solution to eliminate the conflict between the trees and road equipment and urban structures. The people need and should be informed about all parameters, options, benefits and harm of each action that stimulate or inhibit the planting of a tree in the sidewalk.

Full textAbstract:
Os agroecossistemas consistem em complexas relações tróficas entre plantas, herbívoros, e seus inimigos naturais. Sabe-se que a maioria das plantas é capaz de produzir compostos voláteis, utilizados como sinais químicos por diferentes grupos de insetos. Esses voláteis podem ser produzidos de forma constitutiva em plantas sadias, ou seja, sem indução. Por outro lado, a produção de voláteis induzidos se dá a partir do contato de secreções liberadas pelo fitófago com injurias ocasionadas pela alimentação ou oviposição no tecido vegetal. Para os fitófagos esses voláteis podem sinalizar a presença da planta hospedeira, bem como a presença de coespecíficos e do parceiro sexual. Já para os inimigos naturais, predadores e parasitóides, os voláteis induzidos podem sinalizar a presença do inseto fitófago (presa/ hospedeiro) na planta. Nesse contexto as respostas comportamentais de Diaphorina citri Kuwayama (Hemiptera: Psyllidae), aos voláteis de plantas de murta, Murraya paniculata (L.) Jack (Rutaceae), infestadas ou não por coespecíficos, foram estudadas. Também foram investigadas as respostas dos psilídeos aos voláteis de plantas de Citrus sinensis (L.) Osbeck (Rutaceae) infectadas por bactérias causadoras do Huanglongbing ou HLB, uma das mais sérias doenças dos citros. Nos bioensaios visando compostos repelentes a D. citri, foram testados os voláteis de plantas de goiaba, Psidium guajava L.(Myrtaceae) e sua interferência na localização de plantas de Citrus limonia (L.) Osbeck (Rutaceae) pelos psilídeos. As respostas comportamentais foram mensuradas em olfatômetro Y e de quatro vias. Antes de estabelecer os bioensaios de olfatometria foram realizados estudos do comportamento sexual de D. citri. Os resultados obtidos evidenciaram que o início da atividade sexual de D. citri ocorreu entre o segundo e terceiro dia após a emergência, e que os psilídeos foram mais ativos durante a fotofase. Quanto às influências dos voláteis de plantas, machos e fêmeas de D. citri responderam diferentemente aos mesmos estímulos olfativos. Assim, os machos foram atraídos apenas aos odores associados às fêmeas. Já as fêmeas, foram atraídas aos odores das plantas, porém, evitando os odores associados aos machos, inclusive de plantas previamente infestadas por estes. Verificou-se também, que os adultos de D. citri distinguiram os voláteis de citros com HLB dos voláteis de plantas saudáveis. Sendo assim, ficou nítida a atratividade dos voláteis de plantas infectadas, tanto aos psilídeos machos quanto às fêmeas. Na busca por compostos repelentes, também foi possível demonstrar que os voláteis de P. guajava não somente dificultou à localização de plantas de C. limonia por D. citri, como também repeliram os psilídeos. As descobertas aqui apresentadas poderão auxiliar a elaboração de novas táticas para o manejo comportamental de D. citri.The agro-ecosystems consist of complex trophic relationships between plants, herbivores and their natural enemies. It is known that the majority of plants can produce volatiles compounds used as chemical signals by different groups of insects. These compounds can be produced constitutively in healthy plants, i.e., without induction. In other hand, the production of induced volatiles occurs from the contact of secretions released by phytophagous with injuries caused by feeding or oviposition in plant tissue. For phytophagous, these volatile compounds may signal the presence of the host plant, as well as the presence of conspecifics and the sexual partner. Although, natural enemies, predators and parasitoids, the induced volatiles can signal the presence of phytophagous insects (prey / host) in the plant. In this context, the behavioral responses of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) to plant volatiles of jasmine, Murraya paniculata (L.) Jack (Rutaceae) infested or not by conspecifics, were studied. It was also investigated the responses of psyllids to volatiles of Citrus sinensis infected by bacteria that cause the huanglongbing or HLB, one of the most serious diseases of citrus. Given the studies that aim to identify repellent compounds to D. citri, it was tested plant volatiles of guava, Psidium guajava L. (Myrtaceae) and their impact on plant location of Citrus limonia (L.) Osbeck (Rutaceae) by psyllids. Behavioral responses were measured by Y-tube and four-way olfactometers. Before establishing the olfactometry assays, studies of D. citri sexual behavior were performed. The obtained results showed that the beginning of D. citri sexual activities occurred between the second and third days after emergence, and the psyllids were more active during the photophase. In regard to the effects of plant volatiles, males and females of D. citri differently responded to the same olfactory stimuli. Thus, males were attracted only to odors associated with females. Females were attracted to plant odors, although they avoided odors associated with males, including plants previously infested by them. It was also verified that D. citri adults distinguished volatiles citrus with HLB from volatiles released by healthy plants. Given that, it was clear that volatiles from infected plants were attractive to both males and females psyllids. In search of repellent compounds, also was possible demonstrated that P. guajava volatiles not only hindered the location of plants of C. limonia by D. citri, but also provided repellent effect to psyllids. The findings presented here may help the development of new tactics for the behavioral management of D. citri.

This study aims to discuss the pedagogical ideas of Murray Schafer. “Pedagogical ideas” are here understood as the educational philosophy that guides and composes the practice of teaching. Through the bibliographic review of Schafer‟s work, alongside specialized periodicals and related literature, three central axes that comprise his pedagogical ideas are proposed: ecology, spiritual experience and the aesthetical experience.

Full textAbstract:
L’eau a creusé son chemin jusqu’au cœur des discussions sur le développement durable. Les discours autour de la gestion des eaux soulignent à la fois son abondance dévastatrice et son absence critique : la montée des eaux se juxtapose à la désertification ; les tornades et les inondations répondent à des périodes de sécheresse prolongées. Alors que nous polluons, canalisons et dessalinisons à un rythme toujours croissant, la nature ambiguë de notre relation avec l’eau devient visible. Pendant que nous continuons d’endommager ce qui, par-dessus tout, rend la vie possible, la précarité augmente pour l’ensemble de la population. Il n’est donc pas étonnant qu’un changement de paradigme dans notre compréhension des eaux, devant engendrer une modification dans leur utilisation, soit présenté comme l’un des plus grands et plus pressants défis de notre époque. Ma recherche répond à ce défi. Elle porte sur la poétique de l’espace, c’est-à-dire sur l’étude de la manière dont les êtres humains vivent et interagissent avec leur environnement à travers les arts. Plus précisément, j’explore les relations entre les humains, les eaux et les sons (à la fois propres et générés par les humains) dans la Lower Murray Country (Australie Méridionale). Mon but est de révéler et théoriser ces relations qui évoluent en parallèle afin d’élaborer une cartographie mettant à jour toute une gamme de manières de percevoir et de comprendre ces eaux, et d’être ensuite à même d’utiliser cette pluralité pour remettre en question—et potentiellement imaginer à nouveau—leur construction et représentation culturelles. Afin d’atteindre ce but, j’érige “les eaux” en leitmotiv qui me permet d’unifier ma recherche et me déplacer entre des espaces physiques et théoriques pour mettre en dialogue les individus et leur environnement, tant au niveau local que général. En particulier, je me sers du mouvement des eaux que forment le courant et la résonance pour opérer cette synthèse, mouvement que j’associe à la rythmanalyse et la réverbération (d’après les philosophes Henri Lefebvre et Fran Dyson, respectivement). Je me suis également inspirée du travail du philosophe et poète Édouard Glissant. En particulier, son concept de Relation est une clef pour me permettre de traduire textuellement ces mouvements des eaux. J’applique cette méthodologie aqueuse à presque deux siècles de production musicale—allant des pratiques ngarrindjeri et des ballades coloniales à la musique classique contemporaine et l’art sonore ; et presque deux siècles de modifications touchant au “caractère sonore” des eaux de la Lower Murray Country—matérialisée à travers la déforestation défigurante, la retenue des eaux, l’irrigation mais aussi la salinité croissante des eaux comme des sols. Ainsi, cette thèse se construit selon le principe d’accumulation d’exemples prôné par Glissant (Poetics of Relation 172-4). Elle est structurée autour de quatre sections—quatre visions punctiformes des eaux écrites comme un prélude à une potentielle infinité d’autres. Furtives, partielles, orientées et fragmentées, ces visions procèdent de périodes particulièrement significatives : de périodes pouvant subir des changements, de périodes charnières où des altérations radicales peuvent poindre ou apparaître effectivementWaters are contested entities that are currently at the centre of most scientific discussions about sustainability. Discourse around water management underlines both the serious absence and devastating overabundance of water: rising sea levels compete against desertification; hurricanes and floods follow periods of prolonged drought. As we increasingly pollute, canalise and desalinate waters, the ambiguous nature of our relationship with these entities becomes visible. And, while we continue to damage what most sustains us, collective precarity grows. It is therefore unsurprising that shifting our understanding, and subsequent use, of water has been described as one of the biggest—and most pressing—challenges of our time.My research answers to this challenge. It centres on spatial poetics, that is, on the manner in which people engage and interact with their environment through art. More precisely, I explore the relationships between humans, waters and sound—both intrinsic and human-produced—in Lower Murray Country (South Australia). My aim is to unveil, theorise and create maps of these co-evolving relationships to reveal an array of manners to perceive and relate to these waters; and then draw on this plurality to question—and potentially reimagine—their cultural construction and representation. In order to do so, I transform waters into a leitmotif which enables me to weave my investigation together and move in-between theoretical and physical spaces to bring people and their environments into dialogue, both at the local and global levels. In particular, I draw on the watery movements of flow and resonance to operate this weaving, and associate these with rhythmanalysis and resounding (after philosophers Henri Lefebvre and Fran Dyson, respectively). I am also inspired by the work of philosopher and poet Édouard Glissant and use his concept of Relation as a key to enable me to translate these watery movements textually.I apply this aqueous theoretical frame to nearly two centuries of sonic production—ranging from Ngarrindjeri performance and colonial ballads through to contemporary classical music and sound art; and to nearly two centuries of evolution in the sonic character of Lower Murray Country’s waters—ranging from disfiguring deforestation and damming through to rising salinity and irrigation. As such, this thesis is built on the “accumulation of examples” advocated by Glissant (Poetics of Relation 172-4). It is structured around four sections—four punctiform visions of waters written as a prelude to a potential infinity of others. Furtive, partial, oriented and fragmented, these visions denote times of particular significance: times open to challenge; times of hinges and articulations where radical alteration (can) occur

Questo lavoro vuole scandagliare alcuni punti cardine della riflessione di Murray Bookchin, pensatore che ha attraversato quasi l’intero XX secolo, segnando una svolta nell’ambito dell’elaborazione politica di Abdullah Öcalan e, in parte, orientando l’articolarsi del confederalismo curdo.
Ci si è concentrati dapprima sull’analisi degli snodi fondamentali del pensatore statunitense: dall’elaborazione di un’ecologia sociale - realizzata in particolar modo nel testo L’ecologia della libertà - si è passati poi ad analizzare lo svilupparsi di una proposta ulteriore tutta orientata verso una pratica politica, quella della democrazia diretta (con la sua declinazione nei termini di municipalismo libertario), cui Bookchin approda a partire da una serrata critica all’urbanizzazione moderna colpevole di aver silenziato i cittadini, la loro voce di corpo politico sostanziale e non astratto. Si è evidenziato il nesso, fondamentale per il pensatore, tra giustizia sociale e giustizia ecologica: a suo avviso solo da mutati rapporti tra uomo e ambiente potranno infatti darsi mutate relazioni tra uomo e uomo, che siano sintomo di una reale emancipazione.
Si è poi cercato di rintracciare, seppur brevemente, alcuni spunti di convergenza con quello che, nel campo della prassi, si presenta ancora in una fase embrionale, un tentativo che nel presente ci interroga e che chiede sempre più di essere compreso: il confederalismo democratico curdo.

Thesis (MTh)--University of Stellenbosch, 2011.ENGLISH ABSTRACT: The central problem with which this research is working is: has there been a shift in the members of the Dutch Reformed Congregation Murray (De Doorns) concept of the church, and, if so, how did it affect the role expectation of the ministers? The purpose of the study is to determine the church concept and role expectation of the members of the congregation and to help the congregation to discover their missional identity. It is important that the congregation will learn spiritual discernment. For the purpose of the study the work was done within the field of practical theology on the basis of the cross methology as found in Studying Congregations in Africa ( Hendriks 2004). This practical theology methology works with a constant correlation-hermeneutic between the Word of God and the world, between context and identity. This correlation is called spiritual discernment and when this happens it will lead to a certain strategy, a way of life in which the members of the congregation do not think institutionally (regarding the role of the minister), but where the members themselves stand before God and are open for his guidance to be light and salt for the world. The theological foundation of missional theology on the basis of the doctrine of the Trinity and the practical implications for the church are discussed in Chapter 2. This is normative for missional theology. Chapter 3 is a discussion of the context of the congregation with regard to the current situation in the world, the wider community and the congregation. It is common knowledge that the world is currently in a time of major, fast and unpredictable change. It is important that the congregation will use the change in the way identity is formed in a positive manner by creating an alternative identity in Christ Jesus. The role expectations of the ministers are central to the research problem. In Chapter 4 the researcher gives what he believes to be the normative role of the minister should a congregation want to learn to live with spiritual discernment. For this to happen the ministers need to establish certain faith-forming habits. Without these faith-forming habits it will be impossible for the minister to lead the congregation to live with spiritual discernment. The Dutch Reformed congregation of Murray (De Doorns) which was the focus of the study, was researched by using a qualitative questionnaire and ethnographic research. The results were discussed by triangulation and it thus became clear that there are clear differences with regard to the church model of choice and the role expectations for the ministers. The research shows that there has been a definite shift in the church concept of the members of the congregation. This shift, however has not had a major effect on the role expectations for the ministers. There is thus some degree of conflict between the church concept of the members of the congregation and their role expectations for the ministers. If this conflict is not addressed and the role expectations of the ministers cleared anew, the congregation will not learn to live with spiritual discernment and will not be able to join the missio Dei.
AFRIKAANSE OPSOMMING: Die sentrale probleem waarmee daar in hierdie navorsing gewerk word, is die volgende: Het daar 'n skuif in die kerkbegrip van lidmate in die NG gemeente Murray (De Doorns) gekom en hoe beïnvloed dit hulle rolverwagting van hulle leraars? Die doel van die studie is om die kerkbegrip en rolverwagtinge van die lidmate van die gemeente vas te stel en om die gemeente te help om sy missionale identiteit te ontdek. Die gemeente moet dus geleer word om in die geloof te kan onderskei. Vir die doel van die navorsing word daar binne die veld van Praktiese Teologie aan die hand van die kruis metodiek van Hendriks se Studying Congregations in Africa (2004) gewerk. Die prakties-teologiese metodologie wat gebruik word, sê dat daar die hele tyd ʼn hermeneuties sensitiewe korrelasie tussen Woord en wêreld moet wees; met ander woorde tussen konteks en identiteit. Hierdie korrelasie word geloofsonderskeiding genoem en as dit gebeur, loop dit uit op ʼn bepaalde strategie, 'n manier van lewe waar lidmate se dink nie institutêr is nie (betreffende die rol van die dominee), maar waar hulle self voor die Here staan en oop is vir sy leiding om in hulle konteks lig en sout te wees. Dit is die ideaal waarna gewerk word. In hoofstuk 2 word die teologiese fondasie van die missionale teologie aan die hand van die leer van die Triniteit gelê en word die praktiese implikasies daarvan vir die kerk bespreek. Hierdie is die normatiewe van die missionale teologie. In die derde hoofstuk word die konteks van die gemeente bespreek aan die hand van die huidige situasie in die wêreld, die veranderinge binne die breë gemeenskap en die huidige situasie in die gemeente. Daar word op gewys dat die wêreld tans groot, vinnige en onvoorspelbare veranderinge beleef. Die gemeente sal die impak van hierdie veranderinge op 'n positiewe wyse moet benut deur 'n alternatiewe identiteit in Jesus Christus te skep. Die rolverwagtinge van die leraars staan sentraal in die navorsingsprobleem en om dié rede word daar in hoofstuk vier gefokus op wat die navorser beskou as die normatiewe rol van leraars, indien hulle die gemeente wil leer om geloofsonderskeidend te leef. Leraars behoort bepaalde geloofsvormende gewoontes as prioriteit in hulle bediening te beskou. Sonder die geloofsgewoontes sal die leraar nie die gemeente kan lei om geloofsonderskeidend te leef nie. Die NG Gemeente Murray (De Doorns), wat die fokus van die navorsing was, is by wyse van 'n kwalitatiewe vraelys en deur etnografiese studie nagevors. Die resultate is deur middel van triangulasie bespreek en daaruit het dit duidelik geword dat daar duidelike verskille is wat betref die kerkmodel van voorkeur en die rolverwagting van die leraars. Dis egter duidelik dat daar wel 'n skuif gekom het in die kerkbegrip van die lidmate. Hierdie skuif in kerkbegrip het egter nog nie so 'n groot effek op die rolverwagting wat lidmate van die leraars het nie. Daar is dus 'n mate van konflik tussen kerkbegrip van lidmate en hulle verwagting van die leraars. Indien dit nie aangespreek word en die rolle van die leraars nuut uitgeklaar word nie, sal die gemeente nie leer om geloofsonderskeidend te leef nie en kan die gemeente nie aansluit by die missio Dei nie.

This thesis reports on some applications of murray polygons, which are a generalization of space filling curves and of Peano polygons in particular, to process digital image data. Murray techniques have been used on 2-dimensional and 3-dimensional images, which are in cartesian/polar co-ordinates. Attempts have been made to resolve many associated aspects of image processing, such as connected components labelling, hidden surface removal, scaling, shading, set operations, smoothing, superimposition of images, and scan conversion. Initially different techniques which involve quadtree, octree, and linear run length encoding, for processing images are reviewed. Several image processing problems which are solved using different techniques are described in detail. The steps of the development from Peano polygons via multiple radix arithmetic to murray polygons is described. The outline of a software implementation of the basic and fast algorithms are given and some hints for a hardware implementation are described The application of murray polygons to scan arbitrary images is explained. The use of murray run length encodings to resolve some image processing problems is described. The problem of finding connected components, scaling an image, hidden surface removal, shading, set operations, superimposition of images, and scan conversion are discussed. Most of the operations described in this work are on murray run lengths. Some operations on the images themselves are explained. The results obtained by using murray scan techniques are compared with those obtained by using standard methods such as linear scans, quadtrees, and octrees. All the algorithms obtained using murray scan techniques are finally presented in a menu format work bench. Algorithms are coded in PS-algol and the C language.

This keynote address was delivered on August 6, 2018 at Societas Homiletica at Duke University in Durham, North Carolina and explores the relationship between preaching and identity. The lecture introduces Pauli Murray, a local saint whose activism, writings, and ministry challenged the church and broader society. After a detailed introduction, I consider three principal influences on Pauli’s voice: Cornelia Smith Fitzgerald, Langston Hughes, and James H. Cone. Cornelia Smith Fitzgerald, Pauli’s maternal grandmother, provided a lens for thinking about the ethical and spatial contexts in which sermons arise. Langston Hughes, a fêted poet and author, offered literary inspiration and a model for moving among different genres. James Cone, a path-breaking scholar, gave Pauli vital theological footing and a framework for linking preaching, identity, and activism. Overall, I argue that Pauli Murray makes a singular contribution to the study of African American preaching.

Banks, Kirsten Francesca. "The John Murray Archive, 1820s-1840s : (re)establishing the house identity." Thesis, University of Edinburgh, 2014. http://hdl.handle.net/1842/17858.
Full textAbstract:
This thesis examines the continuing growth of the House of Murray during the 1820s-1840s. Prior to the 1820s, Murray had enjoyed massive success with the publications of the work of Lord Byron, whose celebrity, and the profits generated, contributed significantly to the House’s prestigious reputation. Murray’s move from Fleet Street to Albemarle Street in 1812 also signified the House’s shift from bookselling to publishing, which enabled Murray to attract an increasing number of high-profile names from the worlds of literature, travel and exploration, the sciences, and politics. Murray’s drawing-room at Albemarle Street became renowned throughout the trade for its gentlemanly gatherings, comprising of the luminaries of the day. The four chapters of this thesis explore how Murray (re)established the House identity in different markets during the 1820s-1840s, as the Romantic epoch diffused into an increasingly commercialised era, with new production methods, an expanding marketplace, and increasing competition. Chapter One considers Murray’s use of the drawing room at Albemarle Street to construct a House identity amongst selected members of his inner circle. It also looks at the importance of the Byronic legacy to the House and the means by which Murray sought to protect it. Chapter Two engages with the contrasting side of the House, namely the ‘cheap’ publications, which Murray published in response to the growth of this market in the late-1820s and early-1830s. During this time Murray used some of his well-established assets, such as Byron, Crabbe and the Quarterly Review, to retain the prestige of the House, while attempting to reach new readers within the burgeoning middle class. Chapter Three examines Murray’s correspondence with some of his female authors to consider how the House responded to authors of both genders, and, with reference to ongoing scholarship regarding ‘women’s writing’, questions the veracity of a gender-centric approach when applied to the study of archival materials; the chapter’s findings suggest that both Murray’s male and female authors were treated similarly. The final chapter explores how Murray strove to retain control over the House’s reputation as international trading possibilities developed. The roots of the 'Handbooks' and the 'Colonial and Home Library' are also traced back further than has previously been considered, and read within the context of the ongoing re-branding of Byron discussed in Chapters One and Two. The House’s literary figures, and the Quarterly Review, were used by Murray in the 1840s to promote the values and prestige of the House in America, Europe and the Colonies. This thesis offers much previously unpublished archival material from the John Murray Archive at the National Library of Scotland. It builds upon previous scholarship on John Murray and seeks to contextualise some of these lines of enquiry through providing a sustained study of the House during the 1820s-1840s. It uses quantitative analysis, where possible, to provide further grounding for some of its claims, and situates the findings within the growing body of research in this area. It is the underlying aim of this thesis to foreground the House’s shift from the ‘Romanticism’ of the early-nineteenth century towards the ‘commercialism’ of the mid-nineteenth century, whilst serving as a point of reference for further scholarship on the John Murray Archive during this time period.

The objective of this work is to prove that, within the framework of Vachet's "Crisis of Ideologies", the philosophy of Murray Bookchin does not offer the basis for an ideological renewal. By concentrating our efforts on his notion of complementarity, we will first attempt to prove that it is the central notion of Murray Bookchin's thought. Secondly, we will try to demonstrate, through the analysis of this notion, that we cannot find the basis for an ideological renewal. Our development is divided in two parts comprising of five chapters. The first part, which is divided into two chapters, outlines the theoretical foundations of the notion. In it, we analyze the role of complementarity on an internal social level, and on the new proposed relationship between humanity and the natural world. In the second part, which is divided into three chapters, we examine the forms of his notion of complementarity within his social project, especially, in relation to the notions of community, politics, and economy.

The research centres mainly around the following questions:
* What is the nature of the role of the woman in society?
* What is the nature of role conflict?
* Does the female married teacher experience role conflict?
In the literature study attention was paid to the nature of the
role of the woman in society and the nature of role conflict. Six
areas of the experiencing of role conflict were identified:
negative role conflict in the role as mother, as teacher and
between the two roles and positive in the role as mother, as
teacher and between the two roles. Conflict can be time-based,
strain-based or behaviour-based.
An empirical research was conducted by means of a structured post
questionnaire to determine to which extent the female teacher
with children of her own experiences role conflict.
Finally a summary of the literature study and empirical study was
made. It was found that the female married teacher has a
positive attitude towards her dual role. The only areas where
she experiences role conflict are time-based and strain-based.
Suggestions were made with regard to future research.Skripsie (MEd)--PU vir CHO, 1994

Full textAbstract:
This thesis comprises a biographical sketch of the 1st Duke of Atholl, Lord John Murray, the Scottish magnate and nobleman, 1660 – 1724. A background of his family tree is provided with instances of how his Murray ancestors raised their family into the peerage. Lord Murray would become the 1st Duke of Atholl less than one hundred years later. Discussion then turns to the religious situation during Lord Murray's life. He was raised Episcopalian but converted to Presbyterianism in order to wed Lady Katherine Hamilton, the eldest daughter of the 3rd Duke of Hamilton and his wife, Anne, Duchess of Hamilton in 1683. This marriage had a profound impact on the Murray family and his role in the ensuing years of civil battles and continental wars. Estate matters are set in place against the historical background of the era. Lord Murray's acquisition and control of the Atholl Estate from his father in 1689, is examined. His handling of the contentious Glenlyon Estate is prominently reviewed. The oversight of the Athollmen, the large, mainly Highland army loyal to the Atholl banner, who fought for the Crown in the Covenanting Wars of Scotland, and Lord Murray's youthful experiences during his father's leadership and later, his own, are explored. Murray's political fortunes from his early career through to his statesmanship in Westminster are examined. His leadership of the Commission of Inquiry into the Glencoe Massacre and his rise to Secretary of State for Scotland in 1696, resignation and fall, and his resurgence under Queen Anne, as the most vocal magnate opposing the Incorporating Union of 1707, the loss of his wife and heir, the repercussions of the early eighteenth-century Jacobite rebellions, his response to his sons' involvement in the uprisings and his final years finish the work.

Full textAbstract:
Vegetation along the River Murray floodplains has been shown to be in a severe state of decline. This decline is amplified by the impositions of river regulation. In South Australia, where vegetation losses have been great, regeneration is limited and may result in not only individual tree losses but also widespread population decline. This study aimed to examine the relationship between river flows and the regeneration process in populations of Eucalyptus camaldulensis and Eucalyptus largiflorens. The current structure of the populations was examined to determine if a viable number of varying age-classed trees were present. Tree surveys conducted at Banrock Station determined that while densities were low for both species, E. camaldulensis had a more sustainable population structure than E. largiflorens. Growth stages for both species illustrated highly clumped distribution, which is believed to correspond with river flooding magnitudes and frequencies. To address the potential link between tree distribution and flooding within the River Murray, a hydrological analysis was conducted for Banrock Station using river flows at the South Australian border from 1900 to 2003. The amount of time growth stages for each species were inundated was found to be greatly reduced under regulated flows compared to natural flows. This has resulted in shifted localized regeneration patterns corresponding with E. camaldulensis' greater demand for inundation than E. largiflorens. Moderate magnitude flows have been most impacted by regulation, and consequently these are the very flows needed for floodplain tree population maintenance. Flowering and seed fall for E. camaldulensis and E. largiflorens were monitored at Banrock Station for 22 months to identify losses in reproductive potential resulting from tree decline. While seed viability was not affected by vigour, trees with visually reduced vigour were found to produce less fruit and had reduced seed fall, as well as a reduced rate of fruit development. Dendrochronological techniques were applied to floodplain trees. Age and size relationships could be established, implying that such techniques can be applied in South Australia to high quality sites. Growth responses within cohorts were similar and easily matched between individuals illustrating cyclic, but not necessarily seasonal correlations. This work verified the preferential selection of younger trees for dendroecological studies, and identified a relationship between on moderate flows and measurable girth expansion in both floodplain tree species.Thesis (Ph.D.)--School of Earth and Environmental Sciences, 2004.

Full textAbstract:
Murray bail et frank moorhouse sont deux ecrivains australiens contemporains. Le theme de l'innocence se retrouve dans leur oeuvre qui remet en cause la vision idyllique de l'australie consideree comme nouvel eden pour ses avancees sociales. C'est le repli sur un contentement beat favorise par l'eloignement du reste du monde que mettent en evidence les ouvrages des deux ecrivains. Les illustrations et les metaphores de la beance australienne combinent le vide geographique d'un continent en grande partie desertique et la vacance spirituelle d'une societe livree au beotisme. Cet etat d'innocencepercu negativement est aussi lie a l'histoire d'une ancienne colonie qui, jeune nation, s7est longtemps satisfaite de la protection de la grande-bretagne et des etats-unis, et qui, dans son complexe d'inferiorite, s'est contentee des seconds roles et de l'imitation. L'oeuvre de bail et de moorhouse manifeste neanmoins une ambivalence : si elle porte temoignage de l'inferiorite australienne et la denonce, elle manifeste cependant la tentation de revanche d'une societe post-coloniale en marche vers la maturite et l'affranchissement. C'est ainsi que la mere-patrie et le grand frere americain sont demythifies. Les maux de la societe australienne n'en sont pas pour autant gommes dans une oeuvre qui met en scene les souffrances et rebellions suscitees par le philistinisme et l'oppression morale. Les ouvrages de frank moorhouse, tout particulierement, defient le moralisme en brisant bien des tabous, aussi bien des point de vue des moeurs que de l'ecriture. S'inscrivant en reaction contre le realisme, l'oeuvre des deux auteurs offre aussi un regard lucide, souvent sceptique, sur le monde et notre facon de l'apprehender. Elle est a ce titre une interrogation sur la notion de realite et sur la condition humaine.

Full textAbstract:
This thesis addresses the question “What is the essence of the Murray Darling river system conundrum that is usually posed as an issue of environmental remediation?”- following perceptions of problems in catchment strategy formulation regarding project selection and public consultation. The question is initially seen as having four facets – governance, public, participation and remediation. An initial literature review indicated that previous examination of these topics seemed insufficiently radical or comprehensive for the enquiry’s purposes, seeming not to attribute full humanness to members of the public. A fieldwork program of quasi-anthropological nature was conducted. Interpretation of the fieldwork reports focuses primarily on the lack of attribution of full humanness to members of the public. Interpretive techniques including a phenomenological-style process was applied and found that the district houses a number of unrecognised people “nexors’ occupying linking or nexus roles who exercise personal skills and initiatives to underpin effective remediation outcomes. Towards the end of the fieldwork program, further literature indicated that the initial four-facet nature of the enquiry should be reformulated, to include the overall nature of western society as it appears in the district (in place of participation), to reconstitute the concept of remediation more radically. Governance as a topic is broader than the ways in which it appears in the examined district, and suitable hybridizing of competing world view concepts remains unresolved in this thesisDoctor of Philosophy (PhD)

Den kristna kyrkan i väst befinner sig i en brytningstid. Från att ha haft en självklar plats och röst i samhället förlorar man mer och mer mark i ett postmodernt samhälle. Ideologen Stuart Murray analyserar detta skifte inom den neoanabaptistiska tankeströmningen, och detta arbete syftar till att studera hans tankar i ljuset av annan forskning. Ett urval av Murrays kyrkohistoriska, ecklesiologiska och missiologiska böcker har lästs och jämförts med andra författares texter. De tematiska områden som studerats är främst begreppen kristendom, efterkristendom och den västliga kyrkans ecklesiologiska och missiologiska utmaningar. Kristendomstiden präglar Europas kristenhet på många plan. Murray drar slutsatsen att kyrkan måste dekonstruera och rekonstruera sin lära och sin praxis för att vara trogen sitt ursprung och kunna möta det postmoderna samhällets utmaningar. Arbetet finner att Murrays tankar är användbara verktyg för kristna när de söker vägar ur dagens förtroendekris.

Full textAbstract:
This thesis investigates whether different public accountability forums interact with one another when they oversee the same decision maker. It contributes to the larger study of how decision makers are held to account in constitutional democracies where the simultaneous operation of multiple accountability relationships has become routine. Looking beyond the dominant assumption that multiple forums autonomously assess a decision maker's accountability against different and diverging standards, I aim to understand whether forums can influence the standards against which other forums evaluate the same decision maker. I draw on political and normative understandings of public accountability to answer one central question: do different public accountability forums interact with one another in a way that influences the scope of what a decision maker is obliged to account for and the normative standards against which that account is evaluated? Answering this research question involves examining the mechanisms by which interactions might occur and the motivations of actors to interact. I begin by critically reviewing the literature on multiple accountabilities, arguing that existing approaches can only partially explain how public accountability is constructed in multiple accountability regimes. I argue the focus on typologies of accountability emphasise the attributes of individual forums and overlook the broader dynamics of the accountability regime. I then develop an analytical framework to examine how the interactions between different forums, and other actors, might reshape the accountability dialogue. This framework is used to analyse the case of the Murray-Darling Basin Plan in Australia (2008-2012). By presenting a contextSrich analysis of interactions between forums, and other actors, I find that multiple forums act in concert with one another and other actors to contest and then reshape the standards against which the two decision makers are evaluated. The thesis concludes by discussing the implications of recognising accountability interactions for understanding multiple accountability regimes.

Full textAbstract:
In this dissertation, I analyzed Max Neuhaus’s (1939-2009) and R. Murray Schafer’s (b. 1932) commentary and work regarding noise, its control, and its relationship with the environment from the 1960 to the 1980s. Both Neuhaus and Schafer as well as those more directly involved with noise abatement research and policy were responding to the challenges and possibilities that noise posed in the latter twentieth century. In this project, I delved into these substantial links and argued that responding to and engaging with noise abatement policies was a key impetus to much of their work, which scholarship has yet to critically examine. Inspired by the listening strategies that Neuhaus and Schafer set forth, I also considered ways in which music educators and social activists might approach sound, becoming aural advocates or activists when working in their communities.
The works selected for analysis reflected contemporaneous studies held in the USA and Canada investigating the psychological and physiological impact of noise on humans, animals, and their landscape. Just as these investigations grew into the 1970s, new attention developed towards acoustic ecology and public sound art, both fields dealing with the relationship between sounds, living beings, and the environment. Neuhaus’s works analyzed include the Listen series (1966-76), his New York Times op-ed piece titled “BANG, BOOooom, ThumP, EEEK, tinkle" (1974), and the Emergency Vehicle Siren Redesign project (1978-1989). These Neuhaus projects provided an alternative to the movement towards acoustic ecology put forward by his contemporary, Schafer. Analyses of Schafer and the World Soundscape Project’s (WSP) publications included Ear Cleaning (1967), The Book of Noise (1970), and A Survey of Community Noise Bylaws in Canada (1972).
Featured were primary sources from the Max Neuhaus Papers (Columbia University Rare Book and Manuscript Library), newspaper reviews, and clippings. Also included were interviews with artists/associates of Neuhaus from his performance career (Phil Orenstein) and his Sirens project (Ray Gallon, Owen Greenspan, Herr Lugus, Julia Prospero, and Wolfgang Staehle) as well as Schafer's fellow WSP collaborator, Hildegard Westerkamp.

Full textAbstract:
Using a multi-scale experimental approach, the research undertaken in this thesis investigated the role
of the flood pulse in ephemeral floodplain wetlands of the River Murray, in order to better understand
the impact of river regulation (and permanent inundation) on these wetlands.
An ecosystem-based experiment was conducted on the River Murray floodplain, to compare changes
in nutrient availability and phytoplankton productivity in three ephemeral wetlands (over a drying/reflooding
cycle) with three permanently inundated wetlands. In the ephemeral wetlands, both drying
and re-flooding phases were associated with significant increases in nutrient availability and, in some
cases, phytoplankton productivity. It was demonstrated that the ?flood pulse?, as described by the
Flood Pulse Concept (FPC), can occur in ephemeral wetlands in dryland river-floodplain systems,
although considerable variation in the nature of the pulse existed amongst these wetlands. Results of
this experiment suggest that factors such as the degree of drying and length of isolation during the dry
phase, the rate of re-filling, timing of re-flooding and the number of drying/re-flooding cycles may be
potentially important in producing the variation observed.
Permanent inundation of ephemeral wetlands effectively removed these periods of peak nutrient
availability and phytoplankton productivity, resulting in continuously low levels (of nutrient availability
and phytoplankton productivity). It was concluded that alteration of the natural hydrological cycle in
this way can significantly reduce nutrient availability, primary production and secondary production,
essentially changing the structure and function, the ecology, of these wetlands. Equally, the results of
this experiment indicate that some of the changes resulting from river regulation and permanent
inundation can be somewhat reversed, within a relatively short period of time, given re-instatement of
a more natural hydrological regime.
A mesocosm experiment was used to examine the influence of the dry phase, specifically the effect of
the degree of wetland drying, on patterns of nutrient availability and primary productivity comprising
the flood pulse. Compared to permanent inundation, re-flooding of completely desiccated sediments
increased carbon (C) and nitrogen (N) availability while partial drying generally decreased, or had little
effect on, C and N availability after re-flooding. However, degree of drying had little effect on
phosphorus availability or rates of primary production measured after re-flooding, and it is possible
that these two factors are related. Partial drying reduced rates of community respiration after reflooding,
possibly a reflection of the reduced carbon concentrations measured in these mesocosms in
this phase of the experiment. Degree of drying also influenced the macrophyte community (measured
after three months of flooding), with plant biomass generally decreasing and species diversity
increasing as the degree of drying increased (with the exception of complete sediment desiccation
which had lasting negative effects on both macrophyte biomass and species diversity).
The results of the ecosystem and mesocosm experiments were utilised, in addition to results collected
from the same experiment conducted at two smaller scales (minicosms and microcosms), to assess
whether the effects of hydrological regime on nutrient availability at the ?wetland? scale could be
replicated in smaller-scale experiments. None of the smaller-scaled experiments included in this
investigation were able to replicate the specific response to hydrological regime recorded at the
ecosystem scale, however the mesocosm experiment did produce results that were more similar to
those at the ecosystem scale than those produced by the mini and microcosm experiments. The
results of this study indicated that extrapolation of results from small-scale experiments should be
undertaken with caution, and confirmed that a multi-scale approach to ecological research is wise,
where large-scale field experimentation and/or monitoring provides a check on the accuracy, and
hence relevance, of conclusions reached via mesocosm experiments.
