Current trends in the global tourism industry: evidence from the United States

Tourism is one of the largest U.S. industries, serving millions of international and domestic tourists yearly. Tourists visit the U.S. to see natural wonders, cities, historic landmarks, and entertainment venues. Americans seek similar attractions as well as recreation and vacation areas. Tourism competes in the global market, so it is important to understand current trends in the U.S. travel industry. Therefore, this article offers insight into important trends and suggests strategies for policy makers involved in the travel and tourism industry.

Evaluation of different methods for Plasmodia detection, in well defined population groups in an endemic area of Brazil

In Brazil, more than 500,000 new cases of malaria were notified in 1992. Plasmodium falciparum and P.vivax are the responsible species for 99.3% of the cases. For adequate treatment, precoce diagnosis is necessary. In this work, we present the results of the traditional Plasmodia detection method, thick blood film (TBF), and the results of alternative methods: Immunofluorescence assay (IFA) with polyclonal antibody and Quantitative Buffy Coat method (QBC)® in a well defined population groups. The analysis were done in relation to the presence or absence of malaria clinical symptoms. Also different classes of immunoglobulins anti-P.falciparum were quantified for the global analysis of the results, mainly in the discrepant results. We concluded that alternative methods are more sensitive than TBF and that the association of epidemiological, clinical and laboratory findings is necessary to define the presence of malaria.

Global warming in Amazonia: impacts and Mitigation

Global warming has potentially catastrophic impacts in Amazonia, while at the same time maintenance of the Amazon forest offers one of the most valuable and cost-effective options for mitigating climate change. We know that the El Niño phenomenon, caused by temperature oscillations of surface water in the Pacific, has serious impacts in Amazonia, causing droughts and forest fires (as in 1997-1998). Temperature oscillations in the Atlantic also provoke severe droughts (as in 2005). We also know that Amazonian trees die both from fires and from water stress under hot, dry conditions. In addition, water recycled through the forest provides rainfall that maintains climatic conditions appropriate for tropical forest, especially in the dry season. What we need to know quickly, through intensified research, includes progress in representing El Niño and the Atlantic oscillations in climatic models, representation of biotic feedbacks in models used for decision-making about global warming, and narrowing the range of estimating climate sensitivity to reduce uncertainty about the probability of very severe impacts. Items that need to be negotiated include the definition of "dangerous" climate change, with the corresponding maximum levels of greenhouse gases in the atmosphere. Mitigation of global warming must include maintaining the Amazon forest, which has benefits for combating global warming from two separate roles: cutting the flow the emissions of carbon each year from the rapid pace of deforestation, and avoiding emission of the stock of carbon in the remaining forest that can be released by various ways, including climate change itself. Barriers to rewarding forest maintenance include the need for financial rewards for both of these roles. Other needs are for continued reduction of uncertainty regarding emissions and deforestation processes, as well as agreement on the basis of carbon accounting. As one of the countries most subject to impacts of climate change, Brazil must assume the leadership in fighting global warming.

A política industrial chinesa como determinante de sua estratégia going global

China has experienced not only high rates of economic growth as well as an unprecedented competitive international insertion since the turn of the century. This process was not guided solely by market forces or influenced by Government intervention in the economy. Although much has been argued that China's "going global" strategy is rooted in state action, and especially its policy of exchange rate depreciation and trade policy incentives for exports and investments abroad, we argue that the major determinant of this strategy, which established the basic conditions for industrial competitiveness, was its industrial policy. The focus of this article is on the changes in China's industrial structure, emphasizing that Chinese industrial policy is a central determinant of its international insertion strategy.

Antecipando o futuro: a agenda política para a governança econômica global

Este artigo analisa a agenda política para a governança econômica global para os próximos cinqüenta anos. Segundo o autor, o grande crescimento populacional proveniente dos países pobres induzirá uma maior participação desses países na tomada de decisão no âmbito internacional, fomentando a troca de informações e experiências entre os países ricos e pobres. Por fim, há uma breve explanação de outras razões pelas quais os países emergentes deveriam ter maior voz na governança econômica global.

Unipolaridade, governabilidade global e intervenção unilateral anglo-americana no Iraque

As intervenções humanitárias (Bósnia 1995-2003, Somália 1992-1993, Kosovo 1999-2003) e de substituição de regimes ditatoriais (Haiti 1994, Afeganistão 2001-2003, Iraque 2003) na política internacional têm sido objeto de muitas controvérsias acadêmicas durante a última década. O presente artigo, à luz dos teóricos das relações internacionais e da ciência política, analisa a legitimidade dessas atitudes por meio do unilateralismo norte-americano.

Going Global: an organizational study of Brazilian foreign policy

This study analyzes the impact of globalisation on the organization and strategies outlined by the Brazilian Ministry of Foreign Affairs. The study intends to understand how countries from the periphery deal with new institutional challenges resulting from globalization, using the case of the Brazilian diplomatic service.

O Brasil na iniciativa BRIC: soft balancing numa ordem global em mudança?

As opções de política externa do Brasil são limitadas, tendo em conta os recursos materiais superiores das grandes potências establecidas. Soft balancing envolve estratégias institucionais, tais como a formação de coalizões ou ententes diplomáticas limitadas, como BRIC, para restringir o poder das grandes potências estabelecidas. Os países BRIC tinham constado dentre os precursores mais fortes de mudança da diplomacia mundial e por sua vez se beneficiam mais destas mudanças de poder global. Dentro da ordem global modelada pelas grandes potências por meio de instituições internacionais, aqueles jogadores que operam efetivamente dentro destas como inovadores, formadores de alianças e porta-vozes, e que ao mesmo tempo conservam soberania e independência têm o potencial de influir sustancialmente os resultados de políticas futuras.

When emergent countries reform global governance of climate change: Brazil under Lula

Due to its recent economic success, Brazil is considered an emerging country, but is it an emerging power concerning global environmental governance? This article argues that although Brazil has a sui generis profile, it can only be considered an emerging power in some environmental regimes, such as global climate change. Thus, international relations theory needs more analytical instruments to assess the impact of emerging powers in global environmental governance

Emerging global partnership: Brazil and China

The Lula era has witnessed a changing bilateral strategic partnership between China and Brazil, having the interlocutions between both countries became more substantial, comprehensive and influential.

In doing so, both sides need to enhance the ties not only in terms of economic cooperation but also of social interaction
