This study shows the importance of the basic spectro-temporal song parameters in territorial contests between male songbirds. Chiffchaff and willow warbler were selected as model species for their phylogenetic and ecological similarity, strong territorial behaviour, but very different singing styles. We found that bigger males of both species sing lower pitched songs and that males of both species adjust their behaviour according to song pitch of their rival simulated by playback. Thus, it seems that both species use song pitch to acoustically assess the body size of their rivals. We also show that song length and syllable rate are important features of the song, probably signalling short-term motivation to escalate territorial conflict.

abstract: There has been much debate in the world of academia over the valuation of conglomerates. This thesis proposes the use of the EVA theory in explaining fluctuations in conglomerates’ valuation, and we believe that ROIC, WACC, and ROIC-WACC are three indicators that to a certain extent explain these valuation fluctuations. Through analysis of a sample containing 23 conglomerates, this thesis finds that ROIC, WACC, and ROIC-WACC exhibit positive correlation with valuation fluctuations. In the case study on Fosun, this thesis finds that ROIC-WACC is highly correlated with Fosun’s valuation fluctuations and next with ROIC. Thus this thesis conjectures that for investment companies for which investment capital is derived largely from insurance float, such as Fosun, ROIC-WACC is a better valuation tool. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2015

abstract: Executive compensation design involving equity shares has been widely used in Europe, the United States and other developed countries where the capital markets are relatively mature. In China, due to the differences in industries, ownership structure, stages of enterprise development, constraints faced by the firms, the executive compensation design using equity shares tends to vary accordingly. For the state-owned companies, the situations are more complex than others. This complexity has not been a focus of the past literature, particularly on the compensation contract design and its subsequent implementation. Based on Coase contract theorem, agency theory and human capital theory, I examined how different state-owned firms vary in their approaches on managerial stock compensation design using a case study approach. The thesis concludes with a summary of major findings and a discussion of policy implications. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2016

Vega, considerando os fatores associados à senescência floral e perda de vida decorativa. Os experimentos foram conduzidos em delineamento inteiramente casualizado, em esquema fatorial. Em todos os experimentos, as rosas foram mantidas em ambiente de laboratório com 20±2ºC e 67±3% UR, padronizadas em 50 cm e realizadas as seguintes avaliações (exceto para o experimento 5): perda de massa fresca, massa seca, taxa respiratória, notas de qualidade (escurecimento, turgescência e curvatura), conteúdo relativo de água, carboidratos solúveis e redutores, antocianina e coloração. Para o experimento 5 foi avaliada a quantidade de água absorvida e transpirada das rosas. No primeiro experimento, as flores foram colocadas dentro de uma câmara hermética e expostas ao 1-MCP, por um período de seis horas, nas seguintes concentrações: 1) Água destilada (controle); 2) 1-MCP 100 a ppb; 3) 1-MCP a 250 ppb; 4) 1-MCP a 500 ppb. Ao contrário do tratamento com água destilada, todas as concentrações de 1-MCP foram eficientes para retardar a senescência das flores, com destaque para a de 500 ppb que melhor manteve a qualidade, além de prolongar a vida de vaso das rosas até 19 dias. No segundo experimento, as flores permaneceram nas seguintes soluções de manutenção: 1) Água destilada (Controle); 2) 8-HQC (200 mg.L-1); 3) Sacarose (2%) + 8-HQC (200 mg.L-1); 4) Ácido Cítrico (75 mg.L-1); 5) Sacarose (2%) + Ácido Cítrico (75 mg.L-1); 6) 6- BA (60 mg.L-1); 7) Sacarose (2%) + 6-BA (60 mg.L-1). As rosas foram muito sensíveis à 6-benziladenina, associada ou não à sacarose, e perderam a qualidade aos seis dias de vida de vaso. Em contrapartida, o tratamento com 8-hidroxiquinolina... / Given the lack of studies on postharvest physiology of flowers, this research aims to study the postharvest physiology and keeping quality of Vega cut rose, were observed the factors associated with floral senescence and loss of decorative life. The experiments followed complete randomized design, in factorial arrangement. In all experiments, the roses were kept at room temperature with 20 ± 2ºC and 67±3% UR, standardized at 50 cm and it were analysis (except the fifth experiment): weight loss, dry weight, rate respiratory, quality (browning, turgidity and curvature), relative water content, soluble and reducing carbohydrates, anthocyanin, color and longevity. On the fifth experiment was to evaluation the water absorbed and transpired roses. On the first experiment, the flowers were placed inside an airtight chamber and exposed to 1-MCP for a period of six hours, in these concentrations: 1) Distilled water (control); 2) 1-MCP (100 ppb); 3) 1-MCP ( 250 ppb); 4) 1-MCP (500 ppb). Unlike treatment with distilled water, all concentrations of 1-MCP were effective in delaying the senescence of flowers, however, the concentration of 500 ppb of 1-MCP induced better maintenance of quality and extended vase life of roses to 19 days. On the second experiment, the flowers remained in these following holding solutions: 1) Distilled water (Control); 2) 8-HQC (200 mg.L-1); 3) Sucrose (2%) + 8-HQC (200 mg.L-1); 4) Citric Acid (75 mg.L-1); 5) Sucrose (2%) + Citric Acid (75 mg.L-1); 6) 6-BA (60 mg.L-1); 7) Sucrose (2%) + 6-BA (60 mg.L-1). The roses were very sensitive to 6-benzyladenine, with or without sucrose, and lost quality of six days of vase life. In contrast, treatment with 8-hydroxyquinoline has proved the most promising to maintain the quality of the flowers, for ten days. On the third experiment, the roses were treated this way: 1) Distilled water (Control), 2) STS (1 mM) ... (Complete abstract click electronic access below)

As árvores com troncos classificados como sendo de baixo valor comercial, por uma das duas razões acima indicadas, deveriam ser preservadas, pois são importantes como produtoras de sementes, fonte de alimentos, abrigo para animais e preservação da floresta, podendo fazer parte, portanto, da reserva legal ou do montante que não deve ser explorado. Por outro lado, alguns empresários do ramo de móveis designs se interessam pela utilização de partes do tronco que tenham os ocos. No entanto, para que essa utilização seja realizada é importante que se conheça a extensão do oco em relação ao diâmetro e ao comprimento da tora. Dessa forma, para ambas aplicações há a importância de se detectar a existência e se conhecer a extensão do oco na peça. No caso do ultrassom a propagação de ondas é afetada pela presença de um vazio no interior do tronco, provocando variação na velocidade de propagação da onda e na amplitude do sinal emitido. Estas variações poderão ser detectadas pelo equipamento e estudadas para a elaboração de uma imagem que represente a situação interna da tora. Levando em conta os aspectos apresentados, o objetivo geral dessa pesquisa foi avaliar o uso de equipamento de ultrassom, desenvolvido no país, como ferramenta para a detecção de ocos em secções de toras de árvores de espécie nativa e avaliar metodologia de elaboração de imagem (pós-processada) utilizando essa tecnologia (tomografia ultrassônica). Os resultados mostraram que a técnica (ultrassom) e o equipamento utilizado têm sensibilidade para serem utilizados em inspeções de árvores e que, por meio da variação da velocidade foi possível elaborar imagens que reproduziram, de forma aproximada, a presença do oco e de sua extensão. As conclusões da pesquisa indicam a importância de continuidade do estudo, principalmente com foco no desenvolvimento de algoritmos e software dedicados à aplicação da metodologia / Abstract: One of the great problems faced for the entrepreneurs in the legal exploration of the forest is the decurrent losses of the choice of trees, wants either for low the quality of the wood or for the low income. The trees with classified trunks as being of low commercial value, by one of the two reasons above indicated, would have to be preserved, therefore they are important as producing of seeds, source of foods, shelter for animals and preservation of the forest, being able to be part, therefore, of the legal reserve or the sum that does not have to be explored. On the other hand, some entrepreneurs of the branch of furniture designs if interest for the use of parts of the trunk that have the hollow ones. However, so that this use is carried through is important that if it knows the extension of the hollow one in relation to the diameter and the length of the log. Of this form, for both applications it has the importance of if detecting the existence and if knowing the extension of the hollow one in the part. In the case of ultrassom the propagation of waves is affected by the presence of an emptiness in the interior of the trunk, having provoked variation in the speed of propagation of the wave and in the amplitude of the emitted signal. These variations could be detected by the equipment and be studied for the elaboration of an image that represents the internal situation of the log. Taking in account the presented aspects, the general objective of this research was to evaluate the equipment use of ultrasound, developed in the country, as tool for the detention of hollow in log sections of trees of native species and evaluating methodology of image elaboration (after-processed) using this technology (ultrasonic tomography). The results had shown that the technique (ultrasound) and the used equipment has sensitivity to be used in inspections of trees and that, by means of the variation of the speed were possible to elaborate images that had reproduced, of approached form, the presence of the hollow one and its extension. The conclusions of the research indicate the importance of continuity of the study, mainly with focus in the development of dedicated algorithms and software to the application of the methodology / Mestrado / Construções Rurais e Ambiencia / Mestre em Engenharia Agrícola
