Ultra-sonografia virtual: reprodutibilidade intra-observador

OBJETIVO: Analisar a reprodutibilidade intra-observador da ultra-sonografia tridimensional (US3D) real com a US virtual, nas modalidades multiplanar e volumétrica. MATERIAIS E MÉTODOS: Foram examinados, prospectivamente, 132 blocos provenientes de 44 avaliações de 26 conceptos. Dezoito conceptos tinham idade gestacional ecográfica de oito semanas a oito semanas e seis dias, e 26 tinham de dez semanas a dez semanas e seis dias. Realizou-se a US3D, analisando-se: comprimento cabeça-nádega, saco gestacional, saco amniótico, translucência nucal, conduto onfalomesentérico, vesícula vitelínica, membros superiores, membros inferiores, distinção cabeça-tórax, perfil da face, coronal da face, implantação das orelhas, perfil da coluna, coronal da coluna, parede abdominal fechada. Foram obtidos três blocos por concepto para posterior realização da US virtual. A análise estatística foi feita utilizando-se o teste t de Student, o teste de McNemar e o kappa. RESULTADOS: No grupo I, a avaliação ultra-sonográfica 3D real multiplanar versus 3D virtual multiplanar, na análise das variáveis contínuas, evidenciou diferença significativa para todas. Na avaliação das variáveis categóricas, evidenciou-se que todas não apresentaram diferença significativa. No grupo II, a avaliação ultra-sonográfica 3D real volumétrica versus 3D virtual volumétrica demonstrou diferença significativa apenas para a variável implantação de orelhas. Os resultados das análises das variáveis categóricas evidenciaram concordância para a maioria das variáveis analisadas em ambos os grupos. CONCLUSÃO: Há reprodutibilidade intra-observador da US3D com a modalidade virtual, multiplanar e volumétrica.

Working in a digital world: new leadership practices for the development of a digital library workforce

Digital library developments are part of a global move in many sectors of society toward virtual work and electronic services made possible by the advances in information technology. This environment requires new attitudes and skills in the workforce and therefore leaders who understand the global changes underlying the new information economy and how to lead and develop such a workforce. This article explores ways to develop human resources and stimulate creativity to capitalize on the immense potential of digital libraries to educate and empower social change. There is a shortage of technically skilled workers and even more so of innovators. Retention and recruitment is one of the greatest obstacles to developing digital library services and information products.

The Brazilian Business World: the difficult adaptation to globalization

The article deals with the internationalization of Brazilian businesses in the current decade. In the 1990s, Brazil embraced economic neoliberalism and promoted a huge opening up of its economy. At that time, Brazilian companies had to adapt rapidly. Twenty years later, the country has reinforced its presence in Latin America and has ensured a better position in the global markets, especially by through agricultural exports.

Brazil's rise on the international scene: Brazil and the World

Since Cardoso and during Lula's Administration, the international order has undergone significant changes. These changes have allowed the Brazilian foreign policy to mitigate internal effects of an order established by others and, at the same time, to become an active participant in the formulation of the new order. To democratize globalization became the mainspring of Brazilian foreign policy. In the scope, President Lula has maintained the tradition of formulating and programming foreign policy as a State policy, and also has fostered the logistic strategy of incorporation of Brazil into the international scene.

The tale of a Trojan horse or the quest for market access? China and the World Trade Organization

In 2001, China finally joined the WTO. The accession of China was looked forward to by many WTO members and China itself. However, observers had some fears that the Chinese accession would prove to be a Trojan horse, disrupting the working of the WTO. This paper looks into the Chinese accession and its involvement in the WTO Dispute Settlement and argues that these fears seem so far to be unfounded.

Macau in China's relations with the lusophone world

After the transfer of the Portuguese administration to China, Macau kept its role as a bridge between East and West, inspired in the Portuguese settlement 500 years ago. The pragmatism of the Chinese central government, using the Lusophone specificities of this Special Administrative Region, supported the creation of the Forum for Economic and Trade Cooperation between China and the Portuguese-speaking Countries, reviving the statute of the Portuguese language and culture in its own territory.
