A sonoridade do violão na execução musical : um estudo sobre os seus aspectos formadores e análise de duas gravações das Quatro Peças Breves de Frank Martin

A sonoridade é um aspecto importante para a execução violonística. Esse trabalho tem por objetivo estudar a sonoridade com um elemento da execução musical, entender os seus aspectos formadores dentro do âmbito técnico, textual e perceptivo, utilizando-se como exemplo duas gravações das Quatro Peças Breves de Frank Martin. Os resultado são discutidos à luz do embasamento teórico, fazendo-se considerações a respeito das possibilidades de execução musical e como a sonoridade do violão atua nesse contexto.

Assessing Dodd Frank Effects on banking capital structure and Banker´s Pay structure

The systemic financial crisis that started in 2008 in the United States had some severe effects in the economic activity and required the bailout of financial institutions with the use of taxpayer’s money. It also originated claims for stronger regulatory framework in order to avoid another threat in the financial market. The Dodd Frank Act was proposed and approved in the United States in the aftermath of the crisis and brought, among many other features, the creation of the Financial Stability Oversight Council and the tougher inspection of financial institutions with asset above 50 billion dollars. The objective of this work is to study the causal effect of the Dodd Frank Act on the behavior of the treatment group subject to monitoring by the Financial Stability Oversight Council (financial institutions with assets above 50 billion dollars) regarding capital and compensation structure in comparison to the group that was not treated. We use data from Compustat and our empirical strategy is the Regression Discontinuity Design, not usually applied to the banking literature, but very useful for the present work since it allows us to compare the treatment group and the non-treatment group in the year of the enactment of the law (2010). No change of behavior was observed for the Capital Structure. In the Compensation Schemes, however, a decrease was found in the item other compensation for CEOs and CFOs. We also performed a robustness check by running a placebo test on the variables in the year before the law was enacted. No significance was found, which supports the conclusion that our main results were caused by the enactment of the DFA.

Dodd Frank act and the Brazilian capital market: extraterritorial effects of regulation to the over-the-counter derivatives market

This paper aims to describe the chief alterations proposed by the Dodd Frank Act to the American over-the-counter derivatives market and, at the same time, understand the extraterritorial reach of this law compared to the regulatory framework of the Brazilian derivative market. In order to do so, I will study the extraterritorial effects of the law, particularly in reference to the international nature of Title II of the Dodd Frank, which deals with the over-the-counter derivatives, in order to evaluate its reach to foreign markets, especially the Brazilian market.

A foice, o martelo e outras ferramentas de ação política: os trabalhadores rurais e têxteis de Magé/RJ (1956-1973)

A presente tese pretende analisar a ação política dos trabalhadores rurais e têxteis do municí-pio de Magé, Estado do Rio de Janeiro, entre os anos de 1956 e 1973, com destaque para as atuações dessas duas categorias em parceria, bem como as suas formas de organização e lutas. Ao considerarmos este município como um cenário privilegiado para se investigar as conexões entre o rural e urbano – tendo em vista que a cidade foi uma pródiga produtora de alimentos e tornou-se um polo industrial têxtil – nosso intuito será mapear a participação dos diversos partidos políticos, lideranças, grupos e instituições que dialogavam com esses trabalhadores para além do mito da “foice o e martelo”. Deste modo, buscamos contribuir com os estudos sobre história do trabalho, enfatizando a articulação entre as lutas coletivas e as ferramentas de ação política utilizadas por esses tecelões e lavradores, analisados de forma conjunta nesta pesquisa.

A história do centro de educação integrada Monsenhor Honório: surgimento e contribuições (Macau /RN - 1956 1966)

The present study objective to construct to the Education‟s History of Centro de Educação Integrada Monsenhor Honório in Macau, in the state of the Rio Grande do Norte. By means of the examination of this Institution of education, we intend to analyze its educative practical in the Fifties years, that this was the first one to offer gymnasial course and, over all, for having formed doctors, engineers, teachers, bachelors and economists in the city and the region during five decades of functioning. For this we use the records as documentary sources available in the institution, in newspapers and in public and private archives in the capital and the interior, beyond interview with former-employees, former-pupils and people who had participated of its creation and, consequently, they had made and they are part of this history. The institution‟s history helped to us to comment the reading of Macau‟s education, propitiating us reflections about pedagogical practical, methods of teaching and school regiment, in the perspective to understand a past still so present and all process for which passed the education, in the context of the proper Macau‟s history. The search results lead us to evidence that the creation of this school, in 1956, represented a landmark in the education of this municipal district, contributing of decisive form in the formation of the macauenses

Tribute to R.G. Boutilier: Skin colour and body temperature changes in basking Bokermannohyla alvarengai (Bokermann 1956)

In amphibians solar basking far from water sources is relatively uncommon since the highly permeable amphibian skin does not represent a significant barrier to the accompanying risk of losing water by evaporation. A South American frog, Bokermannohyla alvarengai (Bokermann 1956), however, spends a significant amount of the day exposed to full sun and relatively high temperatures. The means by which this frog copes with potentially high rates of evaporative water loss and high body temperatures are unknown. Thus, in this study, skin colour changes, body surface temperature, and evaporative water loss rates were examined under a mixture of field and laboratory conditions to ascertain whether changes in skin reflectivity play an important role in this animal's thermal and hydric balance. Field data demonstrated a tight correlation between the lightness of skin colour and frog temperature, with lighter frogs being captured possessing higher body temperatures. Laboratory experiments supported this relationship, revealing that frogs kept in the dark or at lower temperatures (20 degrees C) had darker skin colours, whereas frogs kept in the light or higher temperatures (30 degrees C) had skin colours of a lighter hue. Light exhibited a stronger influence on skin colour than temperature alone, suggesting that colour change is triggered by the increase in incident solar energy and in anticipation of changes in body temperature. This conclusion is corroborated by the observation that cold, darkly coloured frogs placed in the sun rapidly became lighter in colour during the initial warming up period (over the first 5 min), after which they warmed up more slowly and underwent a further, albeit slower, lightening of skin colour. Surprisingly, despite its natural disposition to bask in the sun, this species does not possess a 'waterproof' skin, since its rates of evaporative water loss were not dissimilar from many hylid species that live in arboreal or semi-aquatic environments. The natural history of B. alvarengai is largely unknown and, therefore, it is likely that the herein reported colour change and basking behaviour represent a complex interaction between thermoregulation and water balance with other ecologically relevant functions, such as crypsis.

Chromosomes of Crossopriza lyoni (Blackwall 1867), intraindividual numerical chromosome variation in Physocyclus globosus (Taczanowski 1874), and the distribution pattern of NORs (Araneomorphae, Haplogynae, Pholcidae)

Pholcidae (Haplogynae) encompasses 967 described species, of which only 14 have been cytogenetic analyzed. Several chromosomal features have already been described including presence of meta- and sub-metacentric chromosomes and sex determination chromosome system (SDCS) of the X, X1X2Y, and X1X2 types, which contrast with the telo- and acrocentric chromosomes and SDCS of the X1X2 type typical of entelegyne spiders. To obtain further cytogenetic information for the family, we examined two pholcid species, Crossopriza lyoni (Blackwall 1867) and Physocyclus globosus (Taczanowski 1874) using both conventional staining and silver staining techniques. Crossopriza lyoni exhibited 2n = 23 = 22 + X in males and 2n = 24 = 22 + XX in females, while P. globosus showed 2n = 15 = 14 + X and 4n = 30 = 28 + 2X, both in male adults, 2n = 16 = 14 + XX in female adults and embryos, and 2n = 15 = 14 + X in male embryos. Both species revealed predominately metacentric and submetacentric chromosomes and a SDCS of the X/XX type. The cytogenetic data obtained in this work and those already recorded for C. lyoni indicate interpopulational and intraspecific numerical chromosome variation, suggesting the presence of chromosomal races or cytotypes in this species. The intraindividual numerical chromosome variation observed in male adult specimens of P. globosus may be explained by the presence of cytoplasmatic bridges between germ cells. The use of the silver staining technique to reveal the nucleolar organizer region (NOR) showed that chromosome pairs 4 and 6 and the X chromosome in C. lyoni are telomeric NOR-bearers, and that the chromosome pair 2 in P. globosus possesses a proximal NOR in the long arm.
