A gap analysis of ornithological research in the brazilian state of Roraima

Neste artigo, o esforço de investigação ornitológica no estado de Roraima será investigado utilizando abordagens de análises de lacunas. Basicamente, apresentaremos uma síntese sobre todo o esforço ornitológico feito até o momento em Roraima, visando responder as seguintes questões: (a) quais os locais bem amostrados para aves? (b) quais são as lacunas geográficas de investigação? (c) em que estágio de descobertas está o inventário das espécies de aves em Roraima? (d) quais são os macro-hábitats prioritários para investigação? (e) quais os tipos de vegetação bem investigados e quais os que podem ser classificados como prioritários para investigação? Como resultados, detectamos Oitenta e duas localidades com algum tipo de informação ornitológica. Dentre essas, a Estação Ecológica de Maracá (442 sp), seguido pelo Parque Nacional do Viruá (420 sp), Colônia do Apiaú (320 sp), Mucajaí (267 sp), e Pacaráima (212 sp), são as cinco localidades com maior grau de conhecimento ornitológico dentro do estado. Nos últimos 20 anos apenas duas localidades ornitológicas em Roraima podem ser acrescidas à lista de sítios bem estudados de acordo com o critério de pelo menos 100 espécies registradas (peles, gravações de voz e observações visuais): Parque Nacional do Viruá e a Fazenda Paraense. Cinco áreas são aqui apontadas como lacunas de amostragem da avifauna de Roraima e devem receber prioridade para novos inventários e estudos sobre a avifauna dessa região, são elas: Noroeste do estado, nas áreas junto à fronteira com a Venezuela e divisa com o Estado do Amazonas; Baixo Rio Branco, desde a cidade de Caracaraí à sua foz; Florestas de terra firme no sudeste do Estado; As savanas do nordeste junto à fronteira com a Guiana e as regiões de floresta montana e os tepuis.

Parametric Analysis of Effective Material Properties of Thickness-Shear Piezoelectric Macro-Fibre Composites

A previous study on the characterization of effective material properties of a d(15) thickness-shear piezoelectric Macro-Fibre Composite (MFC) made of seven layers (Kapton, Acrylic, Electrode, Piezoceramic Fibre and Epoxy Composite, Electrode, Acrylic, Kapton) using a finite element homogenization method has shown that the packaging reduces significantly the shear stiffness of the piezoceramic material and, thus, leads to significantly smaller effective electromechanical coupling coefficient k(15) and piezoelectric stress constant e(15) when compared to the piezoceramic fibre properties. Therefore, the main objective of this work is to perform a parametric analysis in which the effect of the variations of fibre volume fraction, Epoxy elastic modulus, electrode thickness and active layer thickness on the MFC effective material properties is evaluated. Results indicate that an effective d(15) MFC should use relatively thick fibres having relatively high shear modulus and relatively stiff epoxy filler. On the other hand, the electrode thickness does not affect significantly the MFC performance.

Usable work of macro-scale cavities in liquids

It is shown that the generation of cavities in a liquid can produce usable work, which is illustrated by the stretching of a string. This work is done during the expansion of the cavity, and not with its collapse. Basic equations are presented for the movement of a device moved by the so called cavity events. A theoretical solution is also proposed, which uses polynomial functions relating the so called "excess of pressure" in the cavity and time. Evaluations of the force generated during the expansion of the cavity showed a mean peak value of about 58 N for the moving container, while measurements with the container fixed to a support showed a peak value of 476 N, considered somewhat overestimated, because high frequency oscillations seem to superpose the mean behavior. Simultaneous phenomena occurring during the cavity events are also described. Series of pictures of the experiments are presented.

Retrospective Voting in Turkey: Macro and Micro Perspectives

Recent studies have shown that party systems in emerging democracies do not always adequately reflect the various cleavages of society. Under such circumstances, retrospective voting may play a more important role than cleavage voting in determining electoral outcomes. For studies of retrospective voting, the choice between macro and micro level as the independent variable is a major methodological issue. Using individual-level data on Turkey, this paper addresses two major questions: (1) Are voters' decisions based on household economic conditions or national economic conditions? Do sociopolitical conditions also count? (2) Does the future evaluation of the economy affect voting decisions apart from past evaluation? Logit models are used in this research to answer these questions.

Brazil and the EU in the global economy. CEPS Working Document No. 371, February 2013

The structure of the world economy has been changing quickly during the last decade. The emerging global economy is much more fragmented than in the past and characterised by different global actors, each one with specific features and roles. In this setting, both Brazil and the European Union play role. This paper, without pretending to provide a full analysis of the European and Brazilian economies, offers a description of their main international economic features to understand their current and future role in the global order.

Brazilian climate policy since 2005: continuity, change and prospective. CEPS Working Document No. 373, February 2013

In the five-year period 2005-09, Brazil has dramatically reduced carbon emissions by around 25% and at the same time has kept a stable economic growth rate of 3.5% annually. This combination of economic growth and emissions reduction is unique in the world. The driver was a dramatic reduction in deforestation in the Amazonian forest and the Cerrado Savannah. This shift empowered the sustainability social forces in Brazil to the point that the national Congress passed (December 2009) a very progressive law internalising carbon constraints and promoting the transition to a low-carbon economy. The transformation in Brazil’s carbon emissions profile and climate policy has increased the potentialities of convergence between the European Union and Brazil. The first part of this paper examines the assumption on which this paper is based, mainly that the trajectory of carbon emissions and climate/energy policies of the G20 powers is much more important than the United Nations multilateral negotiations for assessing the possibility of global transition to a low-carbon economy. The second part analyses Brazil’s position in the global carbon cycle and public policies since 2005, including the progressive shift in 2009 and the contradictory dynamic in 2010-12. The final part analyses the potential for a transition to a low-carbon economy in Brazil and the impact in global climate governance.

Brazilian perspectives on the changing global order and security challenges. CEPS Working Document No. 376, February 2013

This study analyses the current picture and prospects for EU–Brazil relations in the political and security arenas. As actors experiencing relevant changes, albeit in different directions in their respective international status quo, the EU and Brazil have found some common ground for convergence at the macro level on some structural issues, such as the normative framework of a changing global order, the striving for a multipolar world and the relevance and desirability of multilateralism. At the same time, it is argued that they differ significantly as to the strategies pursued in the attainment of those shared interests, resulting in competing, or eventually divergent, policy preferences when addressing specific issues and developments at the international level, limiting the prospects for a deep mutual commitment and engagement in political and security dynamics at the global level.

German macro: how it's different and why that matters. EPC Discussion Paper, May 2016

Do the macroeconomics of the German political establishment really differ from standard western macroeconomics? That question was the starting point for the seminar on ‘German macro: How it’s Different and Why that Matters’, which was held at Heriot-Watt University in December 2015, with financial support from the Scottish Institute for Research in Economics (SIRE) and the Money, Macro & Finance Research Group (MMF). This ebook, edited by George Bratsiotis and David Cobham, is the result of that exercise; six of the papers were presented at the seminar in earlier versions, and the editors sought some additional papers to complete the range of perspectives offered. The authors all sought out to discover whether or not there is something unique about German macroeconomics, and in what ways it differs from standard western macroeconomics; is it true that the former neglects demand management (although it may be quite interventionist in other ways), rejects debt relief and emphasises structural reform designed to improve competitiveness as the (only) key to economic growth? How much of whatever difference exists is due to a well worked out set of ideas in the form of Ordoliberalism? In what way does it relate to Germany’s own experiences in different periods? And how far is this the result of political preferences and how much do the idiosyncrasies of these German views matter, for the development of the Eurozone and indeed the health of the German economy?

Macro determinants of FDI inflows to Japan:an analysis of source country characteristics

This paper examines the source country determinants of FDI into Japan. The paper highlights certain methodological and theoretical weaknesses in the previous literature and offers some explanations for hitherto ambiguous results. Specifically, the paper highlights the importance of panel data analysis, and the identification of fixed effects in the analysis rather than simply pooling the data. Indeed, we argue that many of the results reported elsewhere are a feature of this mis-specification. To this end, pooled, fixed effects and random effects estimates are compared. The results suggest that FDI into Japan is inversely related to trade flows, such that trade and FDI are substitutes. Moreover, the results also suggest that FDI increases with home country political and economic stability. The paper also shows that previously reported results, regarding the importance of exchange rates, relative borrowing costs and labour costs in explaining FDI flows, are sensitive to the econometric specification and estimation approach. The paper also discusses the importance of these results within a policy context. In recent years Japan has sought to attract FDI, though many firms still complain of barriers to inward investment penetration in Japan. The results show that cultural and geographic distance are only of marginal importance in explaining FDI, and that the results are consistent with the market-seeking explanation of FDI. As such, the attitude to risk in the source country is strongly related to the size of FDI flows to Japan. © 2007 The Authors Journal compilation © 2007 Blackwell Publishing Ltd.
