O presente estudo tem por objetivo avaliar o efeito da substituição do potássio pelo sódio no crescimento em diâmetro e na qualidade do lenho de árvores de Eucalyptus grandis, plantadas em espaçamento 3x2 m e fertilizadas com potássio e sódio (no plantio, 6° e 12° mês), visando orientar a fertilização mineral com potássio e sódio em plantações florestais sujeitas ao déficit hídrico. Foram selecionadas 60 árvores de eucalipto, no 101° mês após plantio, em cinco classes de área basal e avaliado o incremento em diâmetro do tronco, a cada 14 dias, de fevereiro de 2006 a setembro de 2012, através de dendrômetros. Para a amostragem do lenho, foram coletados discos em seis posições (base, DAP, 25, 50, 75 e 100%) da altura total das árvores. As amostras coletadas foram utilizadas para avaliação das propriedades anatômicas (fibras e vasos), físicas (densidade básica ponderada através dos métodos da balança hidrostática, da espectroscopia por infravermelho próximo e densidade aparente por densitometria de raios X), mecânicas (resistência e rigidez à flexão estática e resistência à compressão paralela às fibras), químicas (teores de lignina, holocelulose, extrativos e cinzas) e variação radial de Ca, K, Mg, Na e P (por espectrometria de emissão óptica com plasma induzido por laser) segundo os tratamentos de fertilização, classes de área basal, posições radial e longitudinal do tronco. Os resultados mostram que as árvores de eucalipto dos tratamentos potássio e sódio e as de maior classe de área basal, apresentaram taxas de incremento do tronco superiores em relação às árvores controle e demais classes de área basal. Foi verificado efeito da sazonalidade climática no diâmetro do tronco, com períodos de máximo e mínimo crescimento. Com exceção da densidade básica ponderada, todas as outras propriedades do lenho apresentaram efeito significativo dos tratamentos de fertilização. A determinação da densidade básica pelo NIR demonstrou resultados satisfatórios com coeficiente de determinação próximo a 0,70. Maiores valores dos elementos químicos K e Na foram encontrados no lenho das árvores dos respectivos tratamentos. Todos os nutrientes estudados apresentaram maiores valores na posição mais externa do lenho (100% do raio). Os resultados permitem concluir que a fertilização com K e Na induziu maiores crescimentos em diâmetro do tronco e influenciou as propriedades do lenho. A influência da fertilização potássica e sódica demonstrada pelo Eucalyptus grandis nos períodos de déficit hídrico para região estudada é clara, uma vez que a durante os períodos de baixa pluviosidade a variação sazonal do crescimento apresentou-se de forma diferenciada em relação aos períodos com maior quantidade de chuvas. / This study aims to evaluate the replacement of potassium by sodium in diameter growth and wood quality of Eucalyptus grandis trees, planted in spacing 3x2 m and fertilized with potassium and sodium (at planting, 6 and 12th month), order to guide the mineral fertilization with potassium and sodium in forest plantation subjected to water stress. Were selected 60 eucalyptus trees at 101th month, in five classes of basal area and were evaluated the increment in trunk diameter, every 14 days, from February 2006 to September 2012, through dendrometer bands. For sampling the wood, discs were collected in six positions (base, DBH, 0, 25, 50, 75 and 100%) of the total tree height. The samples were used to evaluate the anatomical properties (fibers and vessels), physical (basic density weighted by hydrostatic balance, near infrared spectroscopy and apparent density by X rays densitometry), mechanical (strength and stiffness in static bending and strength in compression parallel to grain), chemical (lignin, holocellulose, extractives and ash contents) and radial variation of Ca, K, Mg , Na, and P (by laser induced breakdown spectroscopy) according to the fertilization treatments, classes of basal area, radial and longitudinal positions of the stem. The results show that the eucalyptus trees with potassium and sodium treatments and larger class of the basal area demonstrated higher rates of increase in stem in relation to control trees and other classes of basal area. Effect of seasonality was found in trunk diameter, with periods of maximum and minimum growth. Except the weighted density, all other properties of the wood analyzed showed significant differences due to fertilization. The determination of the density by NIR showed satisfactory results with coefficient of determination close to 0.70. Higher values of the chemical elements K and Na were found in the tree\'s wood of the respective treatments. All studied nutrients were higher in the wood in external position (100 % of the radius). The results allow to conclue that the fertilization with K and Na induced the largest increases in trunk diameter and influenced the properties of the wood. The influence of sodium and potassium fertilization demonstrated by Eucalyptus grandis in water deficit periods for the region studied is clear, once during periods of low rainfall the seasonal variation of growth presented itself differently in relation to periods with higher amounts of rainfall.

However, they depend on area knowledge and cropping yield. Thus, this study aimed to propose a methodology to estimate the areas cropped with soybeans and corn in Paraná State according to multi-temporal EVI/MODIS vegetation index images for 2010/2011, 2011/2012 and 2012/2013 crop years. In addition, there was a research with spatial autocorrelation soybean yield in Paraná, with EVI vegetation index and meteorological variables in a decennial scale and estimate yield using CAR, SAR and GWR models. In Paraná State, there is a drawback to map soybeans crop since corn sowing period is very close to the first one. Therefore, images from the maximum and minimum vegetative vigour were drawn of each studied crop for mapping soybean and corn crops in order to obtain both cropping areas. Although, for the separation, Spectro Angle Mapper algorithm (SAM) was applied by one of the studied crops, while mapping was obtained by multiplying the other bands. Thus, for spatial statistics application of mapped data, the average EV profile of each municipality was extracted as well as for each multi-temporal image, in order to change them into a decennial scale. According to the spatial statistics of such areas, the descriptive analysis of univariate spatial autocorrelation (global and local) of each ten-day variable was used based on the soybean cycle. A bivariate autocorrelation analysis between soybean yield and the studied varieties were also performed. Finalizing the methodology, variables with the highest significant level by stepwise method were selected and SAR, CAR and GWR models were generated to estimate soybean yield. As results, regarding mappings, the following answers for soybean were found out: r = 0.95 and r = 0.99, and while for corn, the answers were: r = 0.72 and r = 0.95 for 2012/2013 and 2013/2014 crop years in relation to the official data from SEAB. So, it has been proved some great efficiency of this methodology to separate and identify crops. When the descriptive statistics of municipalities for each variable was carried out, it was found out that some regions began an early sowing in relation to other ones in Paraná by the decennial vegetation index. The ten-day scale was also possible to be identified according to the climatic factors that caused soybean yield damage. Based on the analysis of spatial autocorrelation, the greatest similarities occurred in 2011/2012 crop year, the one affected by the weather change, whose yields were similar in the municipalities of Paraná State. For spatial modelling, it was observed that selection of decennial variables was different for each studied crop year, and the best model selected by the validation. And GWR was chosen as the best model by the AIC, BIC and adjusted R² validation criteria. The residuals were randomly distributed throughout all the State, so that spatial autocorrelation could be eliminated. / As estimativas das produções agrícolas têm grande importância, principalmente, no âmbito econômico. No entanto, elas são dependentes do conhecimento da área de cultivo e da produtividade da cultura. Desta forma, este trabalho teve por objetivo propor uma metodologia para estimar as áreas cultivadas com soja e milho em escala municipal no Estado do Paraná a partir de imagens multi-temporais do índice de vegetação EVI/MODIS, para os anos-safras 2010/2011, 2011/2012 e 2012/2013. Além disto, trabalhar com a autocorrelação espacial da produtividade da soja nesse Estado, com o índice de vegetação EVI e variáveis agrometeorológicas em escala decendial bem como estimar a produtividade a partir dos modelos CAR, SAR e GWR. No Paraná, há o inconveniente para mapear a soja devido à proximidade de datas de semeadura do milho. Assim, para o mapeamento da soja e do milho, utilizaram-se imagens englobando o período de máximo e mínimo vigor vegetativo de cada cultura, para se obter a área cultivada das duas. Para a separação, utilizou-se o algoritmo Spectro Angle Mapper (SAM) para uma das culturas e obteve-se o mapeamento da outra pela multiplicação de bandas. Para aplicação da estatística espacial dos dados mapeados, extraiu-se o perfil médio do EVI de cada município e para cada imagem multi-temporal para transformá-los em escala decendial. De acordo com a estatística espacial de áreas, utilizou-se a análise descritiva, de autocorrelação espacial univariada (global e local) de cada variável decendial com foco no ciclo da soja. Também realizou-se a análise de autocorrelação bivariada entre a produtividade da soja com as variáveis em estudo. Finalizando a metodologia, selecionaram-se as variáveis com maior índice de significância pelo método de stepwise e, em seguida, foram gerados os modelos estimados (SAR, CAR e GWR) da produtividade da soja. Como resultados, foram encontradas as seguintes respostas para os mapeamentos da soja r= 0,95 e 0,99, e para o milho de r = 0,72 e r= 0,95 para os anos-safras 2012/2013 e 2013/2014 em relação aos dados oficiais da SEAB. Logo, comprovou-se a grande eficiência da metodologia para separação e identificação das culturas. Quando realizada a estatística descritiva dos municípios para cada variável, verificaram-se regiões que iniciam as semeaduras antecipadas em relação a outras regiões do Estado pelos decêndios do índice de vegetação. Foi também possível identificar os decêndios em que os fatores climáticos causaram danos à produtividade da soja. Na análise da autocorrelação espacial, as maiores similaridades ocorreram no ano-safra 2011/2012, ano afetado pela variação climática, cujas produtividades foram semelhantes nos municípios do Paraná. Para a modelagem espacial, verificou-se que a seleção das variáveis decêndiais foi diferente para cada ano-safra estudado, e o GWR foi escolhido como melhor modelo pelos critérios de validação, AIC, BIC e R² ajustado. Foram encontrados resíduos distribuídos aleatoriamente por todo o Estado, para que assim se eliminasse a autocorrelação espacial

What personal traits are desirable in the band director? What educational qualifications should be required? How much experience should he have before assuming the position of college band director? What should be the organization of the component parts of the band? Who should compose the personnel? What credit should be given for such services? Who should support the organization and supply such equipment as uniforms, library, and instruments?

In the post-Napster era of disruptive innovations, independent artists are managing more nonmusical roles and more revenue streams to remain competitive and earn a living wage from their music. The purpose of this single case study was to explore the financial management strategies that one independent rock band needed to understand music royalties. Disruptive innovation was the conceptual framework used to guide the study. The sample was comprised of 4 members of an independent rock band based in Northeast Ohio. The selected band met the criteria for the study as members who earned revenue from copyrighted works, merchandise, and CD sales. The multiple data sources included face-to-face interviews with band members; public document review of ReverbNation standard policy, Fox licensing agreement, and the IRS W-9 Form; and direct observations of band members during a rehearsal and live performance. Member checking was used to strengthen the credibility and trustworthiness of interpretations. Four themes emerged from the data analysis: organizational governance of band member responsibilities, financial management education and skills, developing multiple revenue streams from royalties, and financial strategies to manage all revenue streams. Social change from this study might include college-level financial training certificate programs designed for artists given their time constraints, mobility, and need to attract financing sources other than major labels.

Ce travail de thèse considère les modes de déformations des verres métalliques produits sous différentes formes (verres massifs, rubans et particules). La déformation hétérogène dans des échantillons massifs de verres métalliques à base de zirconium est étudiée par microscopie électronique à balayage. Le dégagement rapide de l'énergie élastique stockée sous forme de chaleur lors de la déformation est responsable de la fusion locale observée dans les bandes de cisaillement. Le calcul du profil de température autour d'une bande par un modèle analytique est cohérent avec les observations morphologiques et les rapports d'apparition de nano-cristaux dans la zone déformée. La mise en forme par recuit des rubans de verres métalliques a été étudiée. L'étude aboutit à la mise en forme sans fragilisation des rubans appartenant à différentes compositions de systèmes d'alliages dit métal-métal et métal-métalloïde. Un processus de traitement thermique est suggéré pour assurer la redistribution des contraintes imposées avant l'intervention de la fragilité thermique. Un brevet industriel basé sur ces résultats a été conjointement déposé avec un grand fabriquant de montres mécaniques. De nouveaux matériaux composites d'alliages légers commerciaux à base de Mg et d'Al renforcés par des dispersions de particules de verres métalliques ont été réalisés sans porosité. Une amélioration très nette des propriétés mécaniques est obtenue. / This thesis features the two modes of deformation of metallic glasses produced under different forms (bulk, ribbons and particles). Inhomogeneous deformation in bulk samples is studied by scanning electron microscopy. Heat generated by elastic energy release during deformation is responsible for the melting observed in shear bands, and calculations using an analytical model of the temperature profile around a band are consistent with morphological observations and reports of appearance of nano-crystals in or next to deformed areas. Shaping by annealing glassy ribbons was carried out. The study presents successful shaping without embrittlement of ribbons of different metal-metal and metal-metalloid compositions of glassy systems. A heat treatment process is suggested for redistribution of applied stresses before the intervention of thermal embrittlement. A joint patent for exploiting the findings has been filed with a major producer of mechanical watches. Development of new strong and light composite materials by dispersing glassy particles in aluminum and magnesium based matrices is presented and significant improvement in mechanical properties is obtained.

Bibliography: leaves 210-226. Based on 18 months ethnographic fieldwork about the ways in which members of the South Australian Police Band make music. Studies their disconnection from the body of the community, acheived via an embodiment of emotional disconnection; the power of the Department to appropriate a particular order of emotion for the purposes of power; and, the misrecognition of the appropriation of emotion by members of the public who are open to the Department's emotional domination. The context material describes the reasons for the existence of the police band in the police view, while the core material of the thesis is concerned with describing what it is that police band members do, and what they do most of all is, in their own words, experience something that they call "the feel".

This dissertation investigates the learning scenarios where a high-dimensional parameter has to be estimated from a given sample of fixed size, often smaller than the dimension of the problem. The first part answers some open questions for the binary classification problem in the framework of active learning. Given a random couple (X,Y) with unknown distribution P, the goal of binary classification is to predict a label Y based on the observation X. Prediction rule is constructed from a sequence of observations sampled from P. The concept of active learning can be informally characterized as follows: on every iteration, the algorithm is allowed to request a label Y for any instance X which it considers to be the most informative. The contribution of this work consists of two parts: first, we provide the minimax lower bounds for the performance of active learning methods. Second, we propose an active learning algorithm which attains nearly optimal rates over a broad class of underlying distributions and is adaptive with respect to the unknown parameters of the problem. The second part of this thesis is related to sparse recovery in the framework of dictionary learning. Let (X,Y) be a random couple with unknown distribution P. Given a collection of functions H, the goal of dictionary learning is to construct a prediction rule for Y given by a linear combination of the elements of H. The problem is sparse if there exists a good prediction rule that depends on a small number of functions from H. We propose an estimator of the unknown optimal prediction rule based on penalized empirical risk minimization algorithm. We show that the proposed estimator is able to take advantage of the possible sparse structure of the problem by providing probabilistic bounds for its performance.

La recerca en ciències socials desplega un ampli ventall d’aplicacions sectorials per a les quals el màrqueting i, en concret, la comunicació, es posen en pràctica a una multiplicitat de camps. La present investigació se centra en com la comunicació pren sentit al servei dels grups de música, en tant que creadors i responsables d’una obra que desitgen que arribi als públics. Es basa en una escena musical concreta, que engloba els grups de pop i rock que canten en llengua catalana. El producte que aquestes formacions ofereixen al mercat està marcat per la seva característica lingüística, i això condiciona les estratègies de comunicació que se’n deriven. La tesi té tres parts diferenciades. La primera i més extensa desenvolupa teòricament les bases de com la comunicació, com a política de màrqueting, té capacitat per aportar uns beneficis als grups de pop i rock en català. L’objectiu és unir dues disciplines que no han estat abans tractades conjuntament: la comunicació, d’una banda, i la música popular d’un territori concret (el català), de l’altra. A continuació i, abans d’iniciar la part central del treball de camp, basada en el mètode qualitatiu, es confecciona un model que, a partir de l’establiment de set grans categories i múltiples fonts d’informació, permet esbrinar els grups de música pop i rock en català que al llarg d’un període de temps concret han obtingut majors nivells de consum de la seva música i rellevància, en el territori català. Aquest sistema, pretén quantificar quelcom que no es troba documentat de cap altra manera i possibilita definir la mostra de grups de música a entrevistar posteriorment. La part central del treball empíric s’ha basat en entrevistes en profunditat a les formacions musicals que durant l’any 2010 van assolir majors nivells de consum i rellevància, i a professionals i experts del seu entorn: empreses del sector –discogràfiques i de management–, directors artístics de festivals, fires o mercats, periodistes especialitzats, representants de l’àmbit associatiu i l’Administració, etc. Aquesta etapa ha permès resoldre les incògnites que la investigació plantejava, és a dir, sobre el coneixement i actitud que tenen els grups vers la comunicació i el màrqueting, el grau d’ús i aplicació que fan de les seves estratègies, i com, en la seva activitat, estructuren el desenvolupament de la gestió d’aquestes àrees. Finalment, també s’han visualitzat els recursos i tècniques de la comunicació que aporten uns majors beneficis al col•lectiu de grups que conformen la parcel•la estudiada. / El estudio en ciencias sociales despliega un amplio abanico de aplicaciones sectoriales para las cuales el marketing y, en concreto, la comunicación, se ponen en práctica para una multiplicidad de campos.

El objetivo es unir dos disciplinas que no han sido tratadas antes conjuntamente: la comunicación, por un lado, y la música popular de un territorio concreto (el catalán), por el otro. A continuación, y antes de iniciar la parte central del trabajo de campo, basada en el método cualitativo, se confecciona un modelo que, a partir del establecimiento de siete grandes categorías y de múltiples fuentes de información, permite conocer los grupos de música pop y rock en catalán que a lo largo de un período de tiempo concreto han obtenido mayores niveles de consumo de su obra y relevancia, en el territorio catalán. Éste sistema pretende cuantificar algo que no se encuentra documentado de ninguna otra forma y posibilita definir la muestra de grupos de música a entrevistar posteriormente.

Finalmente, también se han visualizado los recursos y técnicas de la comunicación que aportan unos mayores beneficios al colectivo de grupos que conforman la parcela estudiada. / The social science research spreads out a white range of applications for which marketing and, specifically, communication, are applied to multiple fields. The present investigation is focused on how communication gets sense to the music bands’ service, as creators and responsible ones of a work who wish that it arrives to the public. It is based in a concrete musical scene, which includes pop and rock bands that sing in Catalan. The product that these groups offer to the market is marked by its linguistic characteristic, and this determines the communication strategies that are derived from. The thesis has three differenced parts. The first one and the lengthiest develops in theory the bases of how communication, as a marketing politics, has the capacity to contribute benefits to Catalan pop and rock bands. The point is joining two disciplines that have never been put together: communication, on the one hand, and popular music of a concrete region (Catalan), on the other hand. Then, and before starting the field work central part, based in the qualitative method, drawing up a model that, from the establishment of seven major categories and multiple sources of information, allows to find out the Catalan pop and rock music groups that during a concrete period of time have got higher levels of consumption of their music and popularity, in the Catalan region. This system, aims to quantify something that is not documented in any other way and making possible define the sample of bands in later interviews. The central part of the empirical work has been based in interviews to the groups which during 2010 achieved the highest consumption levels and popularity, and to professionals and experts of their business environment: companies in the sector –discographies and manager companies–, festivals’ artistic directors, fairs or markets, specialized journalists, representatives of an association and the Administration, etc. This phase has allowed solve the unknown that the investigation had set out, that is to say, about the knowledge and attitude that the groups have from communication and marketing, the rates of use and application that they do of their strategies, and how, in their activity, structure the development of the management of these areas. Finally, the resources and communication techniquesthat bring greater benefits to the collective groups that make up the studied areahave been visualized.
