Résumé :

This dissertation explores the understanding of origins in late medieval and Renaissance Florence as represented in art and in wider fields of literary and historiographic discourse. Its particular focus is a myth associating the foundation of Tuscany with Noah, which was promoted in a volume of forged texts published by Annius of Viterbo in 1498. Rather than focusing on Annius or his scholarly reception as other writers have done, the thesis attempts to set the myths that he publicised in the context of other stories about origins that circulated in Renaissance Florence. The central part of the thesis consists of three chapters each of which takes its lead from a particular science of origins: etymology, genealogy and archaeology. The topics discussed in them, however, range beyond the strict confines of these disciplines to include such themes as: the shifting narratives of the foundation of Florence; family history as recorded in Florentine ricordanze; portraits as an expression of patrilineal ideology; and the legend of the Florentine Baptistery as a former temple of Mars together with its influence on Renaissance architecture. A recurring theme in these chapters is that of the origin narrative as a myth that serves to justify present-day arrangements or identities. The final chapter develops the theme of origins to encompass ideas of historical recurrence and renewal. In a discussion that draws heavily on the writings of Machiavelli I attempt to show that Florentine cyclical conceptions of history relied on a model of returning to the origin. The chapter closes with a discussion of Renaissance artists who were either perceived as the re-embodiment of an artistic ancestor, a 'new Giotto' for example, or who actively strove to attain such a status. Finally, the conclusion attempts to draw connections between a number of the narratives discussed earlier in the thesis on the basis of a shared fantasy of autonomous male creativity

Résumé :

The diploma thesis deals with the possibilities of applying weather derivatives and catastrophe bonds as alternative risk transfer products, which enable to cope with natural disaster risk in the Czech Republic. The author highlights an obvious increase in occurrence and intensity of extreme climate events resulting into devastating floods. Total costs caused by floods in August 2002, which hadn't been known so far, had important impact on the Czech insurance market. The situation is in many aspects similar to circumstances, which led to the birth of ART products abroad. If the recent tendencies continue, Czech insurers will have to find new ways of dealing with these risks beside the traditional commercial insurance. In accordance with conclusions of this thesis, applying of catastrophe bonds isn't supposed in the future. However, the weather derivatives seem to be an alternative with great potential.

Résumé :

The study is a contextual analysis of flood victimization. Victimization is defined as the social, psychological, and physiological aftermath experienced by victims of a disaster. Disaster researchers concentrate on the victims' characteristics to explain the varying degrees of their victimization, providing only ambiguous results. Theorists such as Kreps, Wildavsky, and Douglas contend that the outcomes of disasters are contingent upon social structure. This analysis treats victimization as one such outcome. The condition and behavior of individuals can be explained by the presence of disaster and the conditions of social organization. A model explains victimization based on individual's attributes (individual resources), his social environment, and the disaster characteristics. This study uses the 1984 Mingo Creek Flood Victims Survey data to test the model. The data contain information measuring victimization. The survey data are linked with 1980 Census tract data. The tract data provide indicators of the social networks. This tract information, the contextual variables, taps the social conditions, including poverty, unemployment, geographic mobility, and family patterns. This study uses factor analysis to identify the dimensions of victimization. Regression tests the relationship between the contextual variables, the individual resource variables, the disaster characteristic variables, and victimization. The results of the analysis show that victimization is multidimensional with different types of variables being significant predictors for each dimension of victimization, one variable indicating the intensity of the disaster, the dollar value of damage victims experienced, is found to be a significant predictor of the psychological, physiological, and social disruption aspects of victimization. Variables measuring the family and unemployment patterns in the victims' census tract are significant predictors of the psychological and social disruption aspect of victimization. The findings provide general support for the proposed model of victimization. However, victimization is multidimensional with each dimension having a unique set of predictors. Based on the findings, this study suggests that future research focus on measurement and conceptualization of the characteristics of disasters and the victims' social environment.

A escrita desta dissertação teve como intuito discorrer sobre as ações do projeto Lastro – Intercâmbios Livres em Arte, entendendo-o como rede de contatos e plataforma de ação para projetos colaborativos. Uma proposta que visa conexões no campo da arte e cultura no contexto América Latina, porém com reverberações além-territórios. Como rede opera em diferentes frentes de trabalho e pensamento, tendo a mobilidade contemporânea como foco de estudo. Esta pesquisa propôs uma ramificação do pensamento sobre mobilidade em formato de cadernos de viagens, aprofundando pontos de vista e abordagens diferenciadas acerca do deslocamento e como este é entendido por artistas, transformando-se em poética. Quatro cadernos que se transmutarão em pequenas publicações via coleção de livros Lastro. Tal trânsito tem como objetivo fomentar projetos editoriais experimentais que atuem como dispositivo questionador e aglutinador. Além disso, tal projeto inaugura o selo editorial Lastro, o que faz nascer mais uma atividade da rede. A realização dessa pesquisa vem auxiliar uma maior compreensão conceitual do Lastro e sua potência política enquanto proposta curatorial rizomática.
The core aim in the writing of this abstract was to discourse on the project named Lastro - Intercâmbios Livres em Arte (ballast –free exchange art) seeing it as an action platform and a network for cooperative projects. A project that seeks the connections of artistic and cultural fields within the Latin-America context, though resounding beyond its limits. As a network it acts in various types of work fronts and thoughts, having a contemporary movability as its study focus. That research has proposed a branching of the thoughts on movability in the shape of travel diaries, deepening points of views and the differentiated approaches regarding movement and how it is understood by artists by shaping it into poetic. Four diaries that will take the format of small publications through the Lastro book collection. The goal of such movement is to promote the experimental publishing projects that may act as a questioning as well as unifying device. Besides, such project also inaugurates the Lastro imprint, and by doing so, we’ll be starting one more activity in its network. The execution of such research intends to enhance the conceptual comprehension of Lastro and its political potentiality as a non-hierarchical curatorship project.

This thesis compares the structures within industrial production, specifically related to time and the perception of it to the reciprocal resistances and responses within post-war art works. Specifically sound, its relationship to both the human quantification of labor and its exploitation in factory. Suggesting that these – the conditions of human work time – are the material by which artists who work with sound construct ulterior time frames either through processes ranging from deep listening the the co-productive activities surrounding electronic dance music.

Texte intégral

Résumé :

[Truncated abstract] Runoff generation behaviour and flooding in a lake dominated catchment are nonlinear, threshold-driven processes that result from the interactions between climate and various catchment characteristics. A complicating feature of the rainfall to runoff transformation, which may have implications for the flood frequency, is that the various surface and subsurface flow pathways are dynamic, heterogeneous and highly nonlinear, consisting of distinct thresholds. To understand the impact of threshold nonlinearities on the rainfall-runoff transformation in such catchments, a systematic examination was carried out to investigate runoff generation behaviour of the catchment itself, the overflow behaviour of a lake in combination with the catchment draining into it, as well as the lake organisation within a lake chain network. Three storage based thresholds were considered: the catchment field capacity storage governing catchment subsurface stormflow, total storage capacity governing catchment surface runoff, and lake storage capacity governing lake-overflow. ... Through these investigations, this thesis has provided valuable insights into the process controls of lake-overflow events and the associated flood frequency behaviour in lake dominated catchments. In particular, the relative roles of climate, soil depth, the soil?s drainage capacity, as well as the relative geometry of the lake vis a vis the contributing catchment, in the determination of the dynamic characteristics of lake-overflow events and associated flood frequency behaviour have been highlighted. In addition, the importance of lake organization, as expressed in terms of the average ratio of catchment area to lake area and the spatial variability of this ratio from upstream to downstream, and their impact upon connectivity and flood frequency have also been explored. The outcomes of this study highlight the importance of thresholds governing flood frequency, and provide insights into the complex interactions between rainfall variability and the various threshold nonlinearities in the rainfall-runoff process, which are shown to have a significant impact on the resulting flood frequency curves. The improved understanding of these process controls will be useful in assisting the 1 management of the catchment-lake system in the study region, and in regions elsewhere. In particular, the outcome of this study can provide guidance towards the adoption of various management strategies for lake chain systems by illustrating the effects of potential flow interruption and retardation as ways to assist in flood prevention and mitigation, whether it is aimed at decreasing the frequency of occurrence of lake overflows, or merely decreasing the flow magnitude for a given return period.

White, Melinda. « Between Floors : The Ups and Downs of Mediated Narrative ». VCU Scholars Compass, 2012. http://scholarscompass.vcu.edu/etd/433.

Texte intégral

Résumé :

“Between Floors: The Ups and Downs of Mediated Narrative” and the accompanying creative remediation project, “Between Floors: Love and Other Blood Related Diseases,” meld theory and practice of print with electronic literature and installation art. I argue that as the medium changes, the narrative is transformed. The narrative can be reconstructed and pieced together as the reader or viewer becomes increasingly involved, even embodied within the work. This embodiment is what Nathaniel Stern calls “Moving and thinking and feeling” (1) and can result in a more direct emotional experience. The form, structure, and medium (sjužet) rely on authorial intention, yet as a narrative becomes more interactive and experiential the feedback loop shifts, placing meaning, message, and construction of narrative (fabula) between media and reader/viewer. This necessarily complicates the notion of authorship, yet within an embodied space, such as the installations included in this analysis, there is a potential for greater emotional understanding between author/artist and reader/viewer. In the print story “Between Floors: Love and Other Blood Related Diseases,” the protagonist, June, visits her father in a hospital after a tragedy and ends up spending the rest of her life there. The metaphor of an elevator throughout the print, electronic, and installation versions furthers the trapped, claustrophobic feeling of the narrative as well as the ups and downs of relationships and grief. Pieces of the narrative remain recognizable through the electronic literature and installation, yet as the reader/viewer is increasingly immersed in the narrative, it becomes his or her own—a more subjective and overwhelming emotional experience. The elevator metaphor extends through the analysis—an emblem of traditional linear narratives and the narrative arc and technological immersion. The analysis explores theories of language, medium, authorship, nonlinearity, interactivity, and embodiment through existing narrative, new media, and installation theorists such as Peter Brooks, Marshall McLuhan, and Nathaniel Stern. This dissertation and to an extent, experiment, uses theory and practice to illuminate narrative using a recombination of existing theory and an original remediation in three distinct forms, to further the understanding of the nature of narratives, media, authors, and readers, while blurring boundaries between disciplines.

Texte intégral

Résumé :

Leonardo da Vinci's art and science have a dynamic relationship that can be used to better understand the role of the individual and the human body within his art. Leonardo believed that movements of the body were expressions of the soul. He also thought that the body was as a microcosm of the physical world. The theories, based in ancient tradition, would be challenged by his work with the human anatomy. By studying his notebooks it becomes evident that Leonardo held nature to be the highest creator of the world but as he worked to understand the human body and through extension the physical world, his ideas about nature and the divine became more incomprehensible. Leonardo's art reflects this turn of perspective as he becomes unable to define the physical world through the human body.

Résumé :

Flood is one of the major natural disasters in Australia. It breaks down transportation and communication systems, disrupts businesses and causes damage to properties, loss of stock, crops and also loss of human lives. Better understanding of the impacts resulting from floods and other natural hazards can help to reduce the damages or losses. Flood damage assessment procedures estimate the impact of flood in monetary terms to help decision makers develop new policies, programs and development plans. This study examines different techniques, procedures and underpinning philosophies that have been used in some major emergency management and insurance organizations in the world such as RAM, ANUFLOOD, and HAZUS and NHRC. From this examination the study finds that none of them are suitable for mitigation and emergency purposes in producing economic flood damage estimation at fine resolution with high accuracy. From this perspective the study develops a rigorous procedure for property level economic flood damage assessment. The assessment procedures are embedded within GIS (Geographic Information System) technology which can model and analyse the multidimensional phenomenon of flood and damage characteristics of residential buildings. The damage estimation procedures developed in this study include flood modelling, collection and organisation of building inventory data; adopting a set of stage-damage curves; and measuring damage at property level. The quality of damage estimates derived from the procedures is highly influenced by quality of input data. The study also includes the implementation of the damage assessment procedure on the study area (a segment of Kororoit Creek and its adjacent area). The study uses data from a number of sources including Melbourne Water, NEXIS, VICMAP, a quick survey and literature. The developed procedure will help many practitioners in flood loss assessment and natural hazard risk management to face the challenges they have in establishing damage estimates with high accuracy.

Résumé :

Images of rural activities become very popular in mosaic floor decoration in the Levant during the Late Antique period. I aim to explore different categories of iconography and discuss the images of people engaged in rural activities, such as pastoralism; hunting, fishing and activities connected with the vintage. I also aim to look at imagery that is often discussed in isolation without relation to other connected iconographic categories. The symbolic meaning of the representations of the zodiac found in synagogues, for example, is often discussed in detail without also looking at the rural calendars that appear in Christian contexts during the same period in the same region. I also want to explore the archaeological evidence for the activities that appear on the mosaic pavements. Studying both the archaeology and the iconography will, I hope, help us understand what the use of these particular categories of iconography in decorative schemes can tell us about the society that created them.

Texte intégral

Résumé :

This paper analyzes the anatomical response of Pinus pinaster Ait. following wounding by flash floods. A total of 14 wood samples were taken from 14 different scarred trees located on the river banks of the Arroyo Cabrera torrent (Spanish Central System). In addition, 20 increment cores were collected from undisturbed and healthy P. pinaster trees to build a local reference chronology. For the injured trees, analysis focused on growth changes in early earlywood (EE) tracheids, namely on differences in (i) lumen size; (ii) cell-wall percentage and cell-wall thickness; (iii) radial length and tangential width of tracheids; as well as (iv) in the abundance of resin ducts in earlywood (EW) and latewood (LW) following wounding. Results indicate that tissues bordering flash-flood wounds are characterized by reduced growth rates and a decrease of EE tracheid lumen area by 51%. In addition, cell-wall percentage increases by 34% in the increment rings formed after the event and significant changes are observed in the radial length and tangential width of EE tracheids. Observations on resin ducts do not yield any significant results. Based on these anatomical parameters, detecting and dating past flash-flood events in growth rings is now possible for Mediterranean species, specifically P. pinaster.

Résumé :

This research studied the relationship between social capital and household resilience. In particular, how bonding and bridging relationships affect household resilience was the question selected to illustrate this relationship between social capital and household resilience. Moreover, how the vulnerability of household impacts household resilience was also empirically examined. Social capital theory and vulnerability paradigm studies were used to discover explanations for why and how social connectedness and social vulnerabilities impact household resilience. Survey questionnaires were used to collect data in the main two cities in Saudi Arabia, Riyadh and Jeddah. A cross-sectional design was used to collect data. Statistical descriptions and inferences were conducted. In fact, multiple linear regression, T-test, and one way ANOVA were the three principal technics used to make statistical inferences. This study empirically found evidence there are relationships between bonding relationships and household resilience, and also relationships between the economic level of the household and household resilience. However, no evidence was found for relationships between bridging relationships and household resilience, or between other vulnerability factors and household resilience. Other vulnerability factors included gender, minority group, and language.

Texte intégral

Résumé :

Out of a total of 2,976 double tax agreements (DTAs), some 60% are signed between a developing and a developed economy. As DTAs shift taxing rights from capital importing to capital exporting countries, the prior would incur a loss. We demonstrate in a theoretical model that in a deal one country does not trump the other, but that the deal must be mutually beneficial. In the case of an asymmetric DTA, this requires compensation from the capital exporting country to the capital importing country. We provide empirical evidence that such compensation is indeed paid, for instance in the form of bilateral official development assistance, which increases on average by six million US$ in the year of the signature of a DTA.

Texte intégral

Résumé :

Throughout history floods have been part of the human experience. They are recurring phenomena that form a necessary and enduring feature of all river basin and lowland coastal systems. In an average year, they benefit millions of people who depend on them. In the more developed countries, major floods can be the largest cause of economic losses from natural disasters, and are also a major cause of disaster-related deaths in the less developed countries. Flood disaster mitigation research was conducted to determine how remotely sensed data can effectively be used to produce accurate flood plain maps (FPMs), and to identify/quantify the sources of error associated with such data. Differences were analyzed between flood maps produced by an automated remote sensing analysis tailored to the available satellite remote sensing datasets (rFPM), the 100-year flooded areas "predicted" by the Flood Insurance Rate Maps, and FPMs based on DEM and hydrological data (aFPM). Landuse/landcover was also examined to determine its influence on rFPM errors. These errors were identified and the results were integrated in a GIS to minimize landuse / landcover effects. Two substantial flood events were analyzed. These events were selected because of their similar characteristics (i.e., the existence of FIRM or Q3 data; flood data which included flood peaks, rating curves, and flood profiles; and DEM and remote sensing imagery.) Automatic feature extraction was determined to be an important component for successful flood analysis. A process network, in conjunction with domain specific information, was used to map raw remotely sensed data onto a representation that is more compatible with a GIS data model. From a practical point of view, rFPM provides a way to automatically match existing data models to the type of remote sensing data available for each event under investigation. Overall, results showed how remote sensing could contribute to the complex problem of flood management by providing an efficient way to revise the National Flood Insurance Program maps.

Salkowe, Richard. « Federal Disaster Declarations and Denials : Analyzing Spatial Equity in the Implementation of the Stafford Act ». Scholar Commons, 2014. https://scholarcommons.usf.edu/etd/5301.

Texte intégral

Résumé :

Federal disaster declarations are authorized by the president under the provisions of the Robert T. Stafford Disaster Relief and Emergency Assistance Act of 1988. Prior studies have found varying levels of political influence associated with the declaration process. Factors including electoral votes, reelection years, congressional committee appointments, geographic location, and party favoritism have been implicated in claims of inequity associated with the distribution of federal disaster assistance. Compounding these concerns is evidence of recurring problems associated with disparities in the long-term recovery from disasters based on social and economic factors. This dissertation is a response to the call for further research into the political dynamics of disaster declarations. Multivariate hierarchical analytical techniques and key stakeholder interviews were utilized to systematically investigate perceived inequities in the implementation of federal disaster policy and the consequences of those inequities with respect to health-related recovery in communities that had differential access to federal resources. The research findings counter broad claims of political motive in the distribution of federal resources after disasters. However, the observation of a disproportionate post disaster stress-related disease burden in portions of the study area is indicative of a procedural inequity that must be addressed. The recently enacted Sandy Recovery Improvement Act of 2013 calls for a review of eligibility criteria for disaster declarations. The findings of this research are intended to contribute to the review process and assist in the reformulation of public policy in order to address the unique needs of previously unconsidered at-risk populations.

Com o intuito de melhor compreender os mecanismos pela qual a peroxidase (POD) está envolvida no bloqueio xilemático em hastes de ave-do-paraíso e como estes podem ser reduzidos ou inibidos, este trabalho teve como objetivos: purificar e caracterizar a POD; verificar o efeito da utilização de inibidores enzimáticos combinados ou não com pHs ácidos e a presença do corte periódico da base da haste sobre a vida pós-colheita dessas flores, avaliar o efeito da aplicação de substratos fenólicos na longevidade das flores e estudar as características inerentes à própria haste, que podem estar influenciando a longevidade das flores de ave-do-paraíso. Para a purificação da POD foi utilizada uma amostra composta de bases de várias hastes mantidas por 8 dias na água. Durante a extração, foi utilizado um processo de separação da POD solúvel da de parede, e o extrato bruto obtido foi purificado por meio da precipitação com sulfato de amônia e por cromatografia gélica. O extrato purificado foi utilizado para a caracterização enzimática. A atividade total no extrato bruto, a massa molecular estimada e o pH ótimo foram semelhantes para as duas isoenzimas. O processo de purificação só foi eficiente para a POD solúvel, e a POD de parede mostrou-se mais sensível aos aumentos de temperatura e apresentou maior afinidade com os substratos. Entre os inibidores enzimáticos testados, o mais eficiente foi o β-mercaptoetanol. No experimento de vaso, as hastes foram colhidas com um florete aberto e distribuídos entre os tratamentos que continham os inibidores metabissulfito de sódio ou azida sódica, combinados com pH 6,0 ou 2,5, aplicados na forma de pulsing por 24 h. Metade das hastes sofreram o corte da base, e a outra metade não. Para as hastes que não sofreram o corte da base, o melhor tratamento foi azida sózica, pH 6,0, que proporcionou maiores valores de massa fresca relativa e retardou o desenvolvimento do balanço hídrico negativo. Já o mesmo inibidor com o pH 2,5 causou toxidez, e por isso foi considerado o pior tratamento. O metabissulfito foi eficiente em retardar o escurecimento da base e reduziu a atividade da polifenoloxidase (PPO). Apesar destes resultados, a longevidade não apresentou diferenças estatísticas entre os tratamentos aplicados. Em outro experimento de vaso, substâncias fenólicas (catecol, 4-metilcatecol, pirogalol, pirocatequina e guaiacol, 10 mM) foram aplicadas como pulsing por 24 h e em experimento subsequente, o guaiacol foi aplicado como pulsing ou solução de vaso em concentrações de 5, 25 e 50 mM. A massa fresca relativa das hastes tratadas com essas substâncias fenólicas foram superiores as das hastes controles nos dois experimentos e o balanço hídrico negativo foi retardado. No entanto, essas hastes apresentaram escurecimento intenso da base, e a longevidade não foi prolongada. No último experimento, as hastes colhidas com um florete aberto foram separadas em 3 grupos de acordo com o diâmetro da base: I – finas (até 10 mm de diâmetro), II – médias (diâmetro maior que 10 e menor que 12 mm) e III – grossas (diâmetro maior que 12 mm). A presença do corte da base a cada 48 h também foi avaliado. Foram avaliadas as relações hídricas, o conteúdo de carboidratos, abertura de florete, tamanho de florete, longevidade, escurecimento da base e atividade da POD. A taxa da absorção de água só foi influenciada pela presença do corte da base, sendo maior para as hastes grossas que sofreram o corte da base, apresentando estas maiores valores de massa fresca relativa. Essas hastes também apresentaram maior abertura de floretes e longevidade. As taxas de transpiração não foram influenciadas pelo diâmetro da haste, nem pela presença do corte da base. O conteúdo de carboidrato variou com o diâmetro da haste, parte da planta avaliada (haste, bráctea ou florete), tempo e presença do corte. O escurecimento foi semelhante entre os 3 grupos e a atividade da POD foi maior nas hastes grossas. O tamanho da bráctea e da sépala aumentou proporcionalmente com o aumento no diâmetro da base. Conclui-se que a POD está mesmo envolvida no processo de obstrução xilemática em hastes de ave- do-paraíso, desempenhando um papel fundamental neste processo que culmina com o murchamento precoce dos floretes. No entanto, outros fatores, como diâmetro da haste e o conteúdo de reserva presente nessas podem estar influenciando a longevidade das flores.
In order to better understand the mechanisms by which the peroxidase (POD) is involved in xylem blockage in stems of bird of paradise and how these xylem blockage can be reduced or inhibited, this work aimed to purify and characterize POD; verify the effect of enzyme inhibitors combined or not with acid pH and the periodical cut of the base of the stem on the postharvest life of these flowers, evaluate the effect of phenolic substrates in the longevity of the flowers and study the characteristics inherent to the stem, which may be influencing the bird of paradise flowers longevity. To purify POD was used a sample of several bases maintained for 8 days in water. For the extraction, a procedure to separate the soluble POD from the cell wall POD was used, and the crude extract obtained was purified by precipitation with ammonium sulfate and by gel chromatography. The extract purified was used for enzymatic characterization. The total activity in the crude extract, the estimated molecular weight and pH optima were similar for both isoenzymes. The purification process was only effective for soluble POD. The cell wall POD was more sensitive to increases in temperature and had a higher affinity for the substrates. β- mercaptoethanol was the most efficient, among the enzyme inhibitors tested. In the vase experiment, stems were collected with an open floret and distributed among the treatments containing inhibitors sodium metabisulfite or sodium azide, combined with pH 6.0 or 2.5, applied as pulsing for 24 h. Half of the stems had undergone the cutting of the base, and the other half didn‟t. For stems that didn‟t have the cut in the base, the best treatment was sodium azide pH6.0, which led to higher values of relative fresh weight and slowed the development of negative water balance. However the same inhibitor at pH 2.5 caused toxicity, and therefore was considered the worst treatment. The metabisulfite was effective in delaying the darkening of the base and reduced polyphenoloxidase (PPO) activity. Despite these results, longevity showed no statistical differences among treatments. In a different vase experiment, phenolic substances (catechol, 4-methylcatechol, pyrogallol, pirocatequina and guaiacol 10 mM) were applied as pulsing for 24 h. and in a subsequent experiment, the guaiacol was applied as a vase solution or pulsing at concentrations of 5, 25 and 50 mM. The stems treated with these phenolic compounds showed higher relative fresh weight than those of control stems of the two experiments and the negative liquid balance was delayed. However, these stems had intense base darkening, and the longevity was not increased. In the last experiment, the stems collected with an open floret were separated into three groups according to the base diameter: I - thin (up to 10 mm diameter), II - medium (diameter greater than 10 and smaller than 12 mm) and III - thick (greater than 12 mm diameter). The base cutting at every 48 h was also evaluated. Were also evaluated the water relations, carbohydrate content, floret opening, floret size, longevity, darkening of the base and POD activity. The rate of water absorption was only changed by the presence of the base cutting, being greater for thick stems that have undergone the base cutting that also showed higher relative fresh weight. These stems also had a greater opening of florets and longevity. Transpiration rates were not influenced by the stem diameter or by the presence of the base cutting. The carbohydrate content changed with the stem diameter, the plant part evaluated (stem, bract or floret), cutting time and cutting presence. Darkening was similar among the three groups and POD activity was higher in thick stems. The size of the bract and sepal increases with the increase in base diameter. In conclusion, POD is really involved in xylem blockage of bird of paradise stems, playing a key role in this process that culminates in early wilting of the florets. However, other factors such as stem diameter and reserves content may be influencing the flowers longevity.

Résumé :

Magíster en Ciencias de la Ingeniería, Mención Matemáticas Aplicadas
Ingeniero Civil Matemático
El gradiente de presión a lo largo de vasos sanguíneos con estenosis es un índice clínico importante para el diagnóstico de la severidad de patologías cardiovasculares. Mientras el estándar clínico para su medida es una cateterización invasiva (medir directamente la presión introduciendo un catéter en los vasos sanguíneos), la resonancia magnética de contraste de fase ha emergido como una prometedora herramienta para permitir cuantificaciones no invasivas de la presión relativa, ligando las medidas de velocidad (resueltas con alta resolución espacial) con la presión relativa vía las ecuaciones de Navier--Stokes. El objetivo de este trabajo es resumir, proponer y comparar distintos métodos de estimación de la presión relativa a través de una estenosis. Para esto usaremos simulaciones numéricas del fluido sanguíneo. Primero resumimos los métodos actuales para estimación de presión relativa, i.e. PPE, STE y WERP. Luego de proponer algunas mejoras a estos métodos, proponemos otra familia de métodos que integran las medidas sobre un volumen de control para recuperar la presión relativa. Realizamos un estudio comparativo de los métodos existentes y de los propuestos en este trabajo usando datos sintéticos perturbados en dimensión dos. PPE consiste en resolver un problema de Poisson para la presión p, usando medidas de velocidad de flujo sanguineo u : grad p = f(u). STE le agrega un término de difusión a este problema, agregando una velocidad ficticia w a divergencia nula. Esto lleva a resolver en la práctica un problema de Stokes: -Delta w +grad p = f(u). Ambos enfoques entregan una estimación de la presión en todo el dominio. En este trabajo proponemos integrar por partes el lado derecho de STE, reduciéndo los ordenes de derivación de las medidas, reduciendo así la propagación del ruido presente en las mediciones. Llamaremos a este método STEint. Por otro lado, WERP toma un enfoque distinto, en el que solo pedimos la diferencia de presión entre dos superficies basada en un balance de energía integral. Este método solo requiere calcular integrales sobre el dominio utilizando la velocidad medida. Esto lo hace muy superior en tiempo de cálculo, sin embargo, no obtenemos una estimación de la presión en todo el dominio, sino que una estimación para la diferencia de presión media entre dos superficie. En esta tesis también introducimos un nuevo enfoque inspirado en el WERP, que llamamos IMRP: en vez de multiplicar por la velocidad e integrar para obtener un balance de energía, multiplicamos por una función test auxiliar con el objetivo de obtener la presión relativa a través de un balance integral de momento. Dos versiones serán P-IMRP y B-IMRP. En síntesis, proponemos una serie de modificaciones de los algoritmos que estiman el salto de presión que en general mejoran los métodos y se pueden resumir como: Integrar por partes para reducir el orden de derivación, disminuyendo la amplificación del ruido. Usar funciones auxiliares distintas a las medidas y libres de ruido, para reducir la varianza y el sesgo de los estimadores. Aproximar la velocidad en el tiempo t=(n+1/2)tau, donde tau es el paso de tiempo, con un esquema u^{n+1/2}=(u^{n+1}+u^{n})/2. Esto reduce la varianza de los estimadores. Concluimos que los métodos más robustos son STEint B-IMRP.

Résumé :

Constituée de cinq chapitres, cette thèse s'intéresse aux mécanismes d'ajustement macroéconomique dans une union monétaire telle que la zone euro. Le premier chapitre examine la réponse de la mobilité du travail aux disparités entre les taux de croissance des salaires et les taux de chômage dans la zone euro. Les résultats indiquent que la mobilité répond aux différences nationales en matière de chômage, en particulier pendant la période de crise récente, mais pas aux différences nationales dans l'évolution des salaires. Le deuxième chapitre étudie l'effet d'équilibre ou de déséquilibre de la mobilité du travail sur les conditions du marché du travail dans la zone euro. Les résultats montrent que même si la mobilité réagit faiblement aux chocs asymétriques et aux caractéristiques structurelles dans la zone euro, elle réduit les écarts dans les conditions du marché du travail. Le troisième chapitre analyse les déterminants de la migration dans la zone euro par rapport à l'Union européenne (UE). L'objectif principal est d'identifier les facteurs qui entravent la mobilité des personnes dans la zone euro. Les principaux résultats indiquent que, mis à part les obstacles culturels et administratifs, un système de sécurité sociale généreux dans le pays d'origine freine également la mobilité des personnes dans la zone euro. Le quatrième chapitre examine le rôle stabilisateur des envois de fonds des travailleurs comme retombées de la mobilité des personnes. Les résultats montrent que les envois de fonds ne jouent pas un rôle stabilisateur ni dans la zone euro ni dans l'UE. Pire encore, les envois de fonds des travailleurs ont tendance à être procycliques dans l'UE. Enfin, le cinquième chapitre s'intéresse au partage des risques dans l’UE et met en évidence le poids des flux de revenus du travail dans le lissage des chocs asymétriques. Les résultats révèlent que le canal de partage des risques le plus important reste le marché du crédit. Le canal du marché des capitaux est quant à lui procyclique. En ce qui concerne les flux de revenus du travail, leur effet de lissage existe mais il est faible
This thesis consists of five essays on macroeconomic adjustment mechanisms in a currency union such as the Euro area. The first essay examines the response of labour mobility to disparities in wage growth and unemployment rate in the Euro area. The results indicate that mobility responds to national differences in unemployment, especially during the crisis period, but not to national differences in wage developments. The second essay investigates the equilibrium or disequilibrium effect of labour mobility on labour market conditions in the Euro area. The findings show that even if mobility responds weakly to asymmetric shocks and structural patterns in the Euro area, it reduces differentials on labour market conditions. The third essay analyses the determinants of migration in the Euro area in comparison with the European union (EU) ; the main purpose being to identify factors that hinder mobility of people in the Euro area. The main results indicate that apart from cultural and administrative barriers, a generous social security system in the country of origin is also a drag to mobility of people in the Euro area. The fourth essay examines the stabilising role of workers' remittances as a spillover effect of labour mobility. The results show that remittances do not play a stabilising role neither in the Euro area, nor in the EU. Worse still, workers' remittances tend to be procyclical in the EU. Finally, the fifth essay looks at the risk sharing in the EU and highlights the weight of labour income flows in smoothing asymmetric shocks. The outcomes reveal that the most important channel of risk sharing remains the credit market. As for the capital market channel, it tends to be procyclical. Regarding labour income flows, their smoothing effect exists but it is low

Résumé :

C. halicacabum (Sapindaceae) is an invasive plant that is considered a nuisance species in Texas riparian environments. Little is known of the tolerance of C. halicacabum to flooding and drought; however, this information may provide insight into the characteristics that contribute to C. halicacabum purported invasiveness. C. halicacabum seedlings (n = 92) were exposed to one of four levels of water availability (flooded, saturated, intermediate and dry) over six weeks under greenhouse conditions. Plant performance was affected by water availability; however, there was no effect on survivorship. Flooded and saturated plants exhibited morphological adaptations; producing adventitious roots, hypertrophy, and aerenchyma tissue. Morphological measures, anatomical responses, and patterns of biomass allocation all indicate that C. halicacabum is able to survive periodic inundation, perform in saturation, and establish and thrive on the drier end of a moisture gradient.

Texte intégral

Résumé :

This thesis argues that some Early Byzantine floor mosaics had, in addition to a practical and decorative role, a supernatural function. By this I mean the images and words depicted within the mosaic were perceived as devices to attract powers from a supernatural dimension, for the benefit of those that walked over the mosaic or the building that housed it. The thesis is ultimately a discussion of the Byzantines' beliefs in the power of art and text, and how they were believed to intervene and affect everyday life. My examination is carried out with a focus on the floor mosaics produced between the fourth and seventh centuries in the Byzantine Empire. Using an iconographic methodological approach, the thesis explores how certain images and words incorporated within mosaic designs can be seen in supernatural terms. To do so, comparable material objects with clearer supernatural functions will be examined. Primary sources that indicate how certain motifs were perceived to bring about powers will also be analysed. In this thesis, I analyse the different kinds of devices that were depicted to attract supernatural powers and explore why those devices were believed to have the ability to generate powers. The thesis illustrates how power could be seen as being rooted in Christianity, magic or more unclear sources. Expanding on this discussion, I explore how a single mosaic could incorporate elements from several sources, dispelling scholarship that portrays the Early Byzantine period as predominately influenced by Christianity. The other key function of the thesis is to emphasise the fact that mosaics can be considered in terms of the conscious design process of their construction, placing them within the same category as gemstones and icons in terms of purposeful objects.

Texte intégral

Résumé :

Natural flow regimes are critical for sustaining biodiversity and river integrity. Floods and droughts form an important component of river systems and control population sizes and species diversity across space and time. Modification of flow regimes, including disruption of the timing, magnitude and duration of flooding, is a global problem, and many new impoundments are planned for large river-floodplain ecosystems in the tropics. Flow modifications may cause dramatic non-linear responses in population sizes and have lasting effects through time, but such topics are poorly investigated over multi-year scales, especially in highly diverse tropical ecosystems. Using a long-term dataset from the Upper Paraná River floodplain, Brazil, I tested for threshold and legacy effects of fish assemblages to flood attributes, such as timing, magnitude, duration, rate of change and variation. Specifically, I hypothesized that long duration, high magnitude floods would elicit threshold responses in long-distance migratory fish species and these responses result in significant legacy effects detectable over multiple years. Consistent positive threshold responses to increasing flood duration and magnitude were detected for many species and not significantly correlated with reproductive guilds. Legacy effects were prevalent (i.e. identified for more than 90% of species) and including flood attributes from previous years increased variance explained in species abundances by 15-20% compared to contemporary flood attributes alone. Contrary to my hypotheses, flood duration did not elicit strong legacy effects and species from the same reproductive guild did not have similar legacy effects models. The prevalence of legacy effects across almost all species in this diverse study system highlights the need to consider such dynamics in other systems. My results provide targets for management and conservation actions, such as environmental flow releases from upstream reservoirs. Environmental flows releases may play a significant role in sustainability of the floodplain and other tropical floodplain ecosystems affected by impoundments.

Texte intégral

Résumé :

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.

Texte intégral

Résumé :

Cette recherche en art et sciences de l’art porte sur les pratiques d’artistes qui documentent l’histoire récente ou l’actualité, dans un environnement déjà intensément traversé de flux d’images, consécutivement à une connexion généralisée à Internet. L'étude s’appuie sur un corpus d’œuvres réalisées depuis 2005 par une douzaine d’artistes et adopte quatre points de vue successifs : celui de l’héritage historique et conceptuel, celui de la médialité, celui du positionnement artistique et celui de la portée politique des œuvres. L’analyse du contexte théorique et historique antérieur aux démarches artistiques étudiées révèle que les artistes concernés ne tentent pas de penser le contemporain sous l’angle de l’innovation ou de réagir par la tactique de la tabula rasa. Ceux-ci entreprennent au contraire de l’aborder par des stratégies qui échappent au temps historicisé, semblables aux démarches médiarchéologistes. L’approche médiale permet d’identifier des logiques néomédiatiques adoptées dans les œuvres documentaires, notamment l’intermédialité, la variabilité et la remédiation. Avec cette dernière, les artistes s’avèrent intégrer au sein de leurs productions des médias de diffusion des images pour rendre visible leur influence sur notre perception du monde et les révéler en tant que dispositifs à subvertir. Par ailleurs, en s’employant à créer des représentations et des récits du réel, les artistes qui les produisent semblent ne pas laisser aux seuls professionnels des médias d’information cette prérogative. Néanmoins, tout en empruntant leur démarche au journaliste et à l’enquêteur, les artistes prennent soin de rompre avec les certitudes auxquelles prétendent les discours journalistiques, en ayant recours à d’autres tactiques dont la plus singulière consiste à altérer visuellement les représentations. Enfin, au-delà des sujets et des approches qui peuvent être très critiques, il apparaît possible de caractériser différemment l’implication politique de ces œuvres et de mettre à jour, à l’ère de l’image fluide, une responsabilité éthique en actes artistiques
This research in art and sciences of art focuses on artistic practices which document recent history or current events, in an environment already saturated by image streams, resulting from a general connection to the Internet. The study is based on a core of works made since 2005 by a dozen artists and follows four successive points of view: one of historical and conceptual heritage, one of mediality, one of artistic position and one of the political scope of the artworks. The analysis of the theoretical and historical context prior to the studied artistic approaches reveals that the artists concerned do not try to think of the contemporary in terms of innovation, let alone reacting by the tactics of tabula rasa. On the contrary, they tackle it with strategies that are not bound by historicised, sequential, and linear time, similar to mediarchaeologic approaches. The medial approach makes it possible to confronted neomediatic logics adopted in documentary works, particularly intermediality, variability and remediation. With remediation, artists integrate within their productions broadcast media images to make visible their influence on our perception of the world and reveal them as an appartus to be subverted. Moreover, by working to create representations and narratives of the real, the artists who produce them appear not to leave the prerogativeto the professionals of the media of information and communication.Nevertheless, while borrowing their approach from the journalist and the investigator, the artists do not pursue the same ends and break away from the certainties that the journalistic narratives claim, by resorting to other tactics of which the most unique is to visually alter the picture. Finally, beyond the topics and approaches that can be very critical, it seems possible to characterisedifferently the political involvement of these works and to update, in the era of the fluid image, an ethical responsibility of the artist that translates into artistic acts

Texte intégral

Résumé :

While there is growing evidence that shade/flood tolerance tradeoffs may be important in distributions of bottomland hardwood trees and indications that they should apply to herbs, no studies have definitively explored this possibility. Four years of field data following historic flooding were supplemented with a greenhouse experiment designed to identify interactions congruent with tradeoffs. Fifteen bottomland species were grown in two levels of water availability and three levels of shade over 10 weeks. Results indicate responses of Fimbristylis vahlii and Ammannia robusta are consistent with tradeoffs. Modification of classical allometric responses to shade by substrate saturation indicates a potential mechanism for the tradeoff in A. robusta. Responses indicating potential for increased susceptibility to physical flooding disturbance are also discussed.

An average of at least one natural disaster is experienced every day worldwide. The frequency, timing, spatial extent and intensity of natural disasters is increasing. In response, this thesis aims to understand socio-economic inequalities in mental health and well-being and whether differential exposure to a major flood event influences this relationship. Findings indicate who you are and where you live is important in the context of a natural disaster. The importance of this research is to ensure health protection of populations with the greatest needs. This approach will help ensure that government expenditure on public health initiatives are appropriately targeted.

Texte intégral

Résumé :

Volcanism associated with the onset of Karoo flood basalt eruptions (c. 180 Ma) at Sterkspruit, South Africa, began with emplacement of thin lava flows before abruptly switching to phreatomagmatic and magmatic activity that formed a nest of craters, spatter and tuff rings and cones that collectively comprise a crater complex >40 km� filled by 9-18 km� of volcaniclastic debris. Phreatomagmatic activity driven by interaction of Karoo magma with groundwater hosted in country rock and crater-filling debris quarried broad, mainly shallow craters (hundreds of metres, but not kilometers deep) into wall-rock. Closely spaced individual vents, the consequence of magma emplaced over a broad area through a network of feeder dikes and stocks, were active at the same time or over short periods of time. Highly ephemeral access of external water to vents drove repeated and reversible switches between explosive to effusive magmatic and explosive phreatomagmatic activity, resulting in vents and craters that grew laterally and vertically into adjacent ones through quarrying and vent migration. Deposits within the Sterkspruit crater complex are dominated by 7-15 km� of massive, unsorted polymict lapilli tuff and tuff breccia juxtaposed with localised fountain-fed lava and strombolian spatter deposits. Transport within the complex was dominated by jets and fountains of volcaniclastic debris and by mass movement. Country-rock breccias indicate that craters grew via a combination of mechanical fragmentation, granulation and mass-movement of 7-12 km� of wall-rock, adding mass and previously locked-up pore-water to the volcanic system. Ash and lapilli, the deposits of plumes 5-15 km high, form a 50-110 m-thick ejecta blanket mantling Clarens Formation country rock that thins gradually away from the crater-complex margins. Explosive volcanism was succeeded by brief fluvial and eolian reworking of volcaniclastic debris and formation of a shallow crater lake 12 km� in extent, and then by voluminous effusion of flood basalt that inundated the Sterkspruit crater complex with lava. Flood basalt magmas involved in Sterkspruit eruptions were chemically heterogenous. This study documents the rapid (perhaps simultaneous) eruption of multiple, chemically distinct basaltic magmas, which cannot be simply related to one another, from one vent site, and possibly many others, within the Sterkspruit crater complex. Five distinct magma types were involved in eruptions at Sterkspruit, indicating that in the early stages of flood basalt eruption (i) magma batches may be small and not simply related to one another, (ii) heterogeneities in the magma source region may be close to each other in time and space, and (iii) eruptions of chemically distinct magmas may take place over short intervals of space and time without significant hybridisation. Formation of the Sterkspruit Complex, and many others like it in South Africa, confirms that the opening phases of Karoo flood basalt volcanism were explosive, and that the volume of the products of explosive volcanism may have important implications for climate change and landscape development associated with the emplacement of large igneous provinces.

Résumé :

Frutto dell’operato di maestranze specializzate ed espressione di un’edilizia di tenore elevato, i rivestimenti pavimentali costituiscono degli importanti indicatori archeologici, non solo come documenti di un sapere artigianale e di una cultura decorativa, ma anche come reperti-guida per una più ampia comprensione delle dinamiche insediative e socio-economiche di specifici ambiti territoriali. Il presente lavoro ha come oggetto lo studio complessivo dei mosaici e dei pavimenti di età antica rinvenuti nel territorio della Basilicata. Attraverso la raccolta e la razionalizzazione di tutta la documentazione esistente, edita ed inedita, ci si è proposti di realizzare un corpus organico che fosse funzionale ad una prima ricostruzione della cultura musiva dell’area indagata nella sua evoluzione storica, dal periodo ellenistico (metà IV sec. a.C.) alle soglie del Medioevo (fine VI sec. d.C.). Il lavoro comprende un totale di 324 pavimentazioni afferenti a diverse tecniche (cementizi decorati, tessellati, opus sectile, a commessi laterizi, a ciottoli e in tecniche miste) e provenienti sia da centri urbani (domus, impianti termale, edifici di culto, basiliche paleocristiane) sia – soprattutto – da contesti extraurbani (villae rusticae e complessi rurali). Ciascuna attestazione è stata oggetto di una schedatura sistematica che si è avvalsa dell’utilizzo di uno strumento di lavoro all’avanguardia. La ricerca, infatti, s’inserisce nel più ampio Progetto TESS di catalogazione dei pavimenti antichi della Penisola, coordinato al livello nazionale dal Dipartimento di Archeologia dell’Università di Padova (database consultabile on-line al sito: http://tess.beniculturali.unipd.it). La banca dati informatizzata ha costituito un ausilio fondamentale, non solo per un rapido e puntuale confronto con i dati relativi ad altre aree geografiche, ma soprattutto per l’organizzazione di un panorama documentario estremamente ampio e frammentario come quello lucano, composto da notizie e pubblicazioni di respiro locale o di più ampia diffusione nazionale. Lo spoglio degli archivi (ove autorizzato) e l’analisi autoptica dei rivestimenti ancora visibili hanno garantito la completezza delle informazioni, consentendo il recupero dei dati tecnici necessari per la creazione del catalogo. La ricca messe di disiecta membra è stata sistematizzata cercando innanzitutto di ricollocare – quando possibile – le singole attestazioni nel proprio contesto architettonico di pertinenza e di analizzarne in dettaglio i singoli elementi costituenti (aspetti decorativi, figurativi, tecnico-artigianali e conservativi). Per migliorare l’organizzazione della documentazione, si è inteso suddividerla in cinque macro-aree omogenee dal punto vista storico-topografico, che corrispondono ai cinque capitoli di cui si compone la prima parte della tesi. Nella seconda sezione, invece, si è cercato di rielaborare criticamente i dati esaminati e evidenziare le linee di tendenza più significative (topografiche, cronologiche, tecniche e decorative) per la ricostruzione di un primo quadro complessivo del patrimonio musivo del territorio indagato.

Résumé :

Typescript. Includes bibliographical references (leaves [279]-287) This thesis examines the growth ring structure of Eucalyptus camaldulensis Dehnhardt and investigates links between ring features and the climatic conditions under which growth took place. Samples of E. camaldulensis from the Barmah Forest (near the River Murray in northern Victoria) were used in the study. E. camaldulensis growth is linked to periodic flooding, and the Barmah Forest contains sites that are frequently flooded. Wood samples were obtained from sites subject to different average flooding frequencies. Trees used in the study grew out of natural regeneration in the 1920's and 1930's and from regeneration trials in the early 1960's. Initial investigation of E. camaldulensis samples revealed ring-like features that were able to be traced on samples by eye. Microscopic investigation showed that there existed considerable variations in the properties of individual rings at different positions on the samples, and that the boundaries between rings were often indistinct. Further examination of E. camaldulensis microstructure was performed on samples from two trees that grew on sites with significantly different flooding regimes. These samples possessed features that formed rings, with rings being successfully matched between samples taken from different heights in the trees. As the complex microstructure of E. camaldulensis did not lend itself to standard dendroclimatological techniques, methods were developed to facilitate the comparison and matching of rings. These methods were also used in the successful matching of ring patterns with the output from a simple climate-based tree growth model. Two sets of E. camaldulensis samples (BS1, with 33 samples, and BS2, with 39 samples) were studied to assess the level of individual variability in ring patterns, and to provide a representative ring pattern for climate comparison. Following the development of methods for identifying samples with similar ring patterns, a subset of similar samples was selected from the BS1 set. A member of this subset was selected to provide a ring-width pattern upon which a representative pattern of ring features for BS1 was based. The rings of the BS2 samples possessed poorer ring definition than the BS1 samples and provided no new or different information. Consequently, the representative ring pattern for BS1 was used in a dendroclimatological investigation for the site. The ring pattern was matched with the output from two tree growth event models. Although rings were matched with growth events over a 27 year period, the high variability of individual ring features prevented matching of particular types of ring features with particular types of climatic events. An investigation of numerical methods for matching ring patterns with ring or growth event patterns, and for identifying samples with similar ring patterns, was performed using signal smoothing and filtering techniques and a dynamic time-warping procedure. Ring matching and identification of similar ring patterns was found to be most successful on samples where the ring patterns, expressed as continuous signals, had similar mean and amplitude values. The techniques were unsuccessful in the matching of signals of different form, such as continuous ring pattern signals and discontinuous growth event signals.

Texte intégral

Résumé :

In 1879 Congress created the Mississippi River Commission (MRC) to develop and coordinate federal flood control policy for the Lower Mississippi River. Through 1927, that Commission clung stubbornly to a "levees-only" policy that was based on the mistaken belief that levees alone could be effective in controlling the flood waters of the Mississippi River. When the levees failed--and they occasionally did--the MRC responded by raising and strengthening the system but refused to adopt a more comprehensive program, one which would include outlets and reservoirs. Finally, a disastrous flood in 1927 forced the abandonment of levees-only and the adoption of a comprehensive plan for the Lower Mississippi River. Predictably, the MRC faced heavy criticism following the failure of its highly-touted levee system in 1927. While certainly the Commission was culpable, there was plenty of fault to go around and a plethora of mitigating circumstances. Developing a plan for achieving adequate flood control along the lower Mississippi River constituted what was probably the most difficult and complex engineering problem ever undertaken by the U. S. Government. Additionally, there were innumerable political and financial constraints that worked to shape MRC policy. This study will endeavor to tell the story of the MRC from its earliest origins through the landmark 1928 Flood Control Act, and, in the process, give evidence to the reality that the Commission did not function independently. As an organization, it relied upon outside forces for its membership, for its jurisdiction, and for the appropriations necessary to carry out its policies. Significantly, these forces were politically driven and did not always, or even often, share the MRC's priorities for the Lower Mississippi River. Even so, the MRC accomplished a great deal in its efforts to protect the Valley from moderate floods, to improve the navigability of the Mississippi River, and to expand significantly the body of knowledge available on the "Father of Waters."

This thesis examines the way the medium of mosaics was adapted locally by the cities of Antioch (modern Antakya, Turkey) and Thysdrus (modern El Djem, Tunisia) during the second and third centuries CE. Compositional differences indicate different conceptions of the medium and locally specific iconography draws on viewers’ local knowledge and experience to situate the city and its inhabitants within the broader context of the Roman empire.

Résumé :

Background: Age-related changes in pelvic floor muscle (PFM) biomechanics may contribute to urinary incontinence in older women; however, empirical evidence is scant. Purpose: This study aimed to understand the age-related changes in the biomechanical properties of the PFMs in women with no major risk factors for urinary incontinence. Methods: Thirty-three nulliparous women (20-64 years) were recruited to study active force, rate of force development, endurance, resistance to passive stretch and stiffness properties of the PFMs using an automated dynamometer. Separate regression analyses were performed to investigate the relationship between age and each outcome measure. Results: No significant relationships were observed between age and any of the outcome measures. Conclusion: The findings from this study do not support the presence of any age-related changes in PFM mechanics among women aged 20-64. Recruiting women over the age of 65 may be essential to detect age-related changes in PFM biomechanics in nulliparous women.

Résumé :

The objective of this thesis was to better understand the epidemiology of caseous lymphadenitis (CLA) and its economic effects on the Australian sheep industries. The work also sought to apply this knowledge to better understand how to control the disease in Australian sheep flocks. The occurrence of CLA in some other species, as a comparison to CLA in sheep, is described in the literature review. However a comprehensive review of research on CLA in all livestock species is not needed to meet the aims of the thesis. The research used serological tests developed in the 1970s and 80s to examine the epidemiology and costs of CLA in Western Australian sheep flocks. Epidemiological techniques were used to determine the main risk factors associated with high incidences of CLA. Controlled experimentation was used to better understand the spread of CLA within flocks. Prevalence data collected at abattoirs and survey techniques were employed to better understand how CLA was being controlled in Australian sheep flocks. It was shown that toxin and cell wall ELISA tests for CLA were useful tools to study the spread of CLA in sheep flocks. Using the serological tests it was estimated that 80 per cent of CLA spread occurs after the second and third shearings. This knowledge was used to design a risk factor study which identified two significant factors associated with high CLA spread, that is in dips and close contact after shearing. These tests also facilitated the study of new CLA infection on wool production. It was found that sheep produce approximately five per cent less clean wool in the year in which they are infected. The main routes for the spread of CLA were from sheep with lung abscesses to those with skin cuts and through dips, rather than from an environment contaminated with Corynebacterium pseudotuberculosis bacteria. A survey of sheep producers found that the prevalence of CLA had decreased from over 50% in the 1970s to approximately 20% in the late 1990s. It also found that current vaccines were being used inefficiently. Large increases in the efficiency of control can be achieved by approximately 70 per cent of producers by using commercially available vaccines and the recommended vaccination programs of two

This work is a research about the esthetic education of worshipper artists that integrate the Companies of Santos Reis do Jardim das Aroeiras and of Jardim Primavera, in Goiânia, Goiás, and it is linked to the research line Education, work and social movements in FE/UFG. Based on a dialectic and historical orientation, mainly, with the contributions of Antonio Gramsci and authors linked to the theoretical and methodological perspective of Marx, it was led the investigation process with procedures and used resources by the bibliographic and empiric research of ethnographic type. Answering to the challenges of the problem previous delimitated, we decided to divide the exposition in four distinct and complementary chapters. Initially, we present a reflection about the concepts and essential implications to the understanding of the thematic referred, specially, in relation to the particularities and senses that hold the terms culture, esthetic, art and education. Based on the reference of Gramsci, we develop, at the second chapter, the analysis of some aspects of the complex social-cultural context in which the life and the knowing of the denominated simple man are processed. The third chapter deals with the deciding, social-historic and contradictories concepts, related to the religion, devotion and tradition phenomenon. At the last chapter, when we articulate the several concepts, we also analyze the aspects that involve a concrete educative situation and shared by worshipper artists of Santos Reis in their courses, meetings and singing moments around the neighborhoods in Goiânia, aiming the comprehension of the mediations, appropriation and socialization of the artistic knowing produced on a determined social-cultural context with their continuities and ruptures. At this research, it was noticed the understanding of the education as an essential phenomenon of constitution, appropriation and transformation of the popular culture, like a social practice historically sited and interested, returned to the concretization of certain desires and attitudes, makings and knowings, ways of being and living, which demands symbolic and material mediations, social interactions and mutual helping, constant repetitions and improved masteries. Besides, it was confirmed the necessity of deepening about the education that it is processed in different moments and spaces of the social life.
Este trabalho é resultado de uma pesquisa sobre a educação estética de devotosartistas que integram as Companhias de Santos Reis do Jardim das Aroeiras e do Jardim Primavera, situadas em Goiânia, Goiás. Vincula-se à linha de pesquisa Educação, Trabalho e Movimentos Sociais, da FE/UFG. Com base num referencial de orientação histórico-dialética, sobretudo, com as contribuições de Antonio Gramsci e de autores vinculados à perspectiva teórico-metodológica marxista, encaminhou-se o processo de investigação com procedimentos e recursos utilizados pela pesquisa bibliográfica e empírica do tipo etnográfica. Respondendo aos desafios da problemática previamente delimitada, optou-se em dividir a exposição em quatro capítulos distintos e complementares. Inicialmente, apresenta-se uma reflexão dos conceitos e pressupostos essenciais ao entendimento da referida temática, especialmente, em relação às particularidades e sentidos que comportam os termos cultura, estética, arte e educação. Com base no referencial gramsciano, desenvolve-se, no segundo capítulo, a análise de alguns aspectos do complexo contexto sociocultural em que se processa a vida e o conhecimento do chamado homem simples. O terceiro capítulo aborda os aspectos definidores, sócio-históricos e contraditórios, relacionados com o fenômeno da religião, devoção e tradição. No último capítulo, articulando os diversos conceitos, analisa-se aspectos que envolvem uma situação educativa concreta e compartilhada por devotos-artistas de Santos Reis em suas jornadas, encontros e cantorias pelos bairros do município de Goiânia, tendo em vista a compreensão do processo de mediação, apropriação e socialização do saber artístico engendrado em um determinado contexto sociocultural com suas continuidades e rupturas. Na pesquisa evidenciou-se o entendimento da educação como fenômeno essencial de constituição, apropriação e transformação da cultura popular, assim como, uma prática social historicamente situada e interessada, voltada à concretização de certas vontades e atitudes, fazeres e saberes, modos de ser e viver, à qual demanda mediações simbólicas e materiais, interações sociais e ajuda mútua, constantes repetições e aperfeiçoados domínios. Ademais, confirmou se a necessidade de um aprofundamento ainda maior sobre a educação que se processa em diferentes momentos e espaços da vida social
