SEASONAL DISTRIBUTION OF MALARIA VECTORS (DIPTERA: CULICIDAE) IN RURAL LOCALITIES OF PORTO VELHO, RONDÔNIA, BRAZILIAN AMAZON

We conducted a survey of the malaria vectors in an area where a power line had been constructed, between the municipalities of Porto Velho and Rio Branco, in the states of Rondônia and Acre, respectively. The present paper relates to the results of the survey of Anopheles fauna conducted in the state of Rondônia. Mosquito field collections were performed in six villages along the federal highway BR 364 in the municipality of Porto Velho, namely Porto Velho, Jaci Paraná, Mutum Paraná, Vila Abunã, Vista Alegre do Abunã, and Extrema. Mosquito captures were performed at three distinct sites in each locality during the months of February, July, and October 2011 using a protected human-landing catch method; outdoor and indoor captures were conducted simultaneously at each site for six hours. In the six sampled areas, we captured 2,185 mosquitoes belonging to seven Anopheles species. Of these specimens, 95.1% consisted of Anopheles darlingi, 1.8% An. triannulatus l.s., 1.7% An. deaneorum, 0.8% An. konderi l.s., 0.4 An. braziliensis, 0.1% An. albitarsis l.s., and 0.1% An. benarrochi. An. darlingi was the only species found in all localities; the remaining species occurred in sites with specific characteristics.

Brazil: an emerging military power? The problem of the use of force in Brazilian international relations in the 21st century

The central goal of this paper is thinking about the Brazilian military power and its linking to the international ambitions of the country in the 21st century. After a comparative analysis to other BRICs and with a historical one about Brazil's strategic irrelevance, we aim to establish what the minimum military capacity Brazil would need in order to meet the country's latest international interests. Similarly, it will be discussed if the National Strategy of Defense, approved in 2008, and the recent strategic agreements signed with France represent one more step toward this minimum military capacity.

Five generations of peace operations: from the "thin blue line" to "painting a country blue"

This article combines both international practice and analytical contributions into a systematic and synthetic presentation of the evolution of peace operations from their modern inception in 1948 to the present. It seeks to serve a didactic purpose in proposing a basic structure for Brazilian scholars' burgeoning debate on peace operations and intervention, rather than a definitive characterization of blue helmet practice. Peace operations' progression is traced through five analytical "generations," each adding a crucial factor distinguishing it from its predecessors. Each generation is placed in relation to changes in the nature of conflict and in the interpretation of the foundational principles of peace operations, and links to broader theoretical issues in International Relations are made explicit at each stage.

A harder edge: reframing Brazil's power relation with Africa

Brazil's rapprochement with Africa during the last decade has been mostly explained as an attempt to improve political dialogue, raise economic interactions, and provide technical cooperation assistance. This article, however, argues that such framework does not sufficiently account for the use of Brazilian material resources in order to attain harder strategic goals towards the continent. By focusing on defense cooperation ties, it highlights an important niche in South-South relations that has also grown exponentially, with important consequences on how Brazil exerts power across the Atlantic.

Swords into ploughshares? China's Soft Power strategy in Southeast Asia and its challenges1

Since the 1990s, alongside China's economic growth, the international community has fostered a general anxiety towards a "China threat." In order to relieve itself from suspicion, China adopted the dual strategies of "harmonious worldview" and "good neighbor policy." The strategies led to the use of soft power in China's foreign policy. China aimed to reduce security concerns implied by the threat theory by supporting an image that caters to international peace and development. This article seeks to explain how China achieves its interests in Southeast Asia through the use of soft power. The authors address the concepts of "harmonious worldview" and "good neighbor policy" and how the twin strategies and soft power have shaped China's foreign policy in recent years. This article aims to provide insights into China's policy options in Southeast Asia in the near future.

China's rising Soft Power: the role of rhetoric in constructing China-Africa relations

As China turns increasingly to the cultivation of soft power in the course of developing its foreign policy, the use of political rhetoric and its explicit and implicit audiences become more and more important, both on a bilateral level and within the international arena at large. Using the case of China's relations with African countries, this article examines key themes within China's diplomatic narrative regarding its role on the African continent and contrasts with Western and African responses.

Conhecendo o "valor do cliente" de um jornal on-line

Com o advento da Internet, uma questão parece peculiar ao marketing: conhecer o comportamento de um "novo" consumidor, o on-line. Uma proposta é o conhecimento do "valor do cliente", que é a percepção do consumidor sobre como atributos de produtos podem propiciar benefícios que o ajudem a atingir suas metas. A teoria de cadeias de meios-fim é a forma de se pensar sistematicamente nessa representação. O método mais amplamente utilizado para atingir as cadeias de meios-fim é o laddering. A pesquisa foi realizada com uma amostra de 78 usuários de um grande jornal on-line. Os principais "valores do cliente" dos usuários do jornal propiciaram conclusões importantes. Foram identificados leitores que se preocupam muito com seus objetivos pessoais, mas que também desejam interagir com os outros e que demonstraram interesse com questões sociais. Com base nisso, implicações gerenciais são discutidas e sugestões para futuras pesquisas são indicadas.

A compra por impulso em ambientes on-line

Este estudo tem como propósito avaliar os antecedentes e as conseqüências da compra por impulso em lojas virtuais da Internet. Para tanto, foi desenvolvido um modelo teórico que procura apresentar as relações existentes entre o ambiente de loja (site), a impulsividade individual, a circulação na loja (navegação no site) e a realização de compras impulsivas. A partir de uma pesquisa survey realizada com compradores de produtos pela Internet, por meio de modelagem de equações estruturais, foi evidenciado que o ambiente do site afeta o nível de impulsividade, a navegação no site e a ocorrência de compras por impulso, bem como se encontrou uma relação entre compra por impulso e emoções positivas. Elementos ambientais que influenciam a compra por impulso foram identificados e rotas para futuras pesquisas apresentadas, juntamente com implicações acadêmicas e gerenciais dos resultados.
