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.

Immune mechanisms underlying the premunition against Plasmodium falciparum malaria

The most unique characteristic of a parasite when it is in its normal host is the ability to make itself tolerated, which clearly indicates that it has sophisticated means to ensure the neutrality of its host. This is true also in the case of Plasmodium falciparum, since after numerous malaria attacks an equilibrium is reached with a chronic stage of infection, characterized by a relatively low parasitemia, and low or no disease (Sergent & Parrot 1935). We shall briefly review the main characteristics of this state of "premunition", and present data suggesting that the underlying mechanisms of defense rely on the cooperation between cell and antibodies, leading to an antibody dependent cellular inhibition of the intra-erythrocytic growth of the parasite.

Estudo do estado fundamental de aglomerados de silício via redes neurais

We introduce a global optimization method based on the cooperation between an Artificial Neural Net (ANN) and Genetic Algorithm (GA). We have used ANN to select the initial population for the GA. We have tested the new method to predict the ground-state geometry of silicon clusters. We have described the clusters as a piling of plane structures. We have trained three ANN architectures and compared their results with those of pure GA. ANN strongly reduces the total computational time. For Si10, it gained a factor of 5 in search speed. This method can be easily extended to other optimization problems.

Interfaces com a indústria

Brazilian chemical industries face several problems regarding Research, Development and Innovation (RDI). The present paper shows that simple cooperation between chemical industries and university laboratories can be a way to overcome some of the present difficulties. The work carried out at LABOCAT has several industrial interfaces. It involves, among other areas of RDI, the development of anti-HIV-protease (and other virus-related-protease) drugs, the establishment of new (industrial) chemical processes and the implementation of industrial (biodiesel and related) plants. A model based on the present so called RHAE programme is proposed in which, parallel to the fellowship awards of this programme, financing participation of Brazilian Agencies would cover process development.

Financial losses in pork supply chain: a study of the pre-slaughter handling impacts

Brazil is amongst the world’s largest swine producers. However, its competitiveness has been vulnerable due to a lack of cooperation between the supply chain players. This condition makes the financial losses to be evaluated taking into account only an individual node, and most of the time, these damages are imputed by swine breeders. Living weight losses occur between the farm to slaughterhouses, and the main cause of these losses is the pre-slaughter handling, especially during animal transportation. In this research, we analyzed the pre-slaughter handling in a swine farm in Brasilândia, MS, Brazil. Analyzed data were provided by five slaughterhouses (farm clients) from the studied region, in which it was considered living weight losses, carcass bruising, animal injury, and death rate. The results indicated that total financial losses represent 160 thousand dollars per year, when taking into account the supply chain management.

Brazilian foreign policy towards South America during the Lula administration: caught between South America and Mercosur

The aim of this article is to analyze Brazil's foreign policy towards the South American region during President Lula's administration. As such, the article intends to highlight two specific dimensions: the extent to which foreign policy during this period has differed from previous periods and the relative importance granted by Brazilian diplomacy to recent cooperation and integration efforts, more specifically the Unasur and Mercosur. The article argues that the Lula administration has behaved differently from its predecessors by prioritizing the building up of Brazilian leadership in South America on several different fronts, especially by strengthening multilateral institutions in the region

Exploring the interplay between Framing and Securitization theory: the case of the Arab Spring protests in Bahrain

This article advances the theoretical integration between securitization theory and the framing approach, resulting in a set of criteria hereby called security framing. It seeks to make a twofold contribution: to sharpen the study of the ideational elements that underlie the construction of threats, and to advance towards a greater assessment of the audience's preferences. The case study under examination is the 2011 military intervention of the countries of the Gulf Cooperation Council in Bahrain. The security framing of this case will help illuminate the dynamics at play in one of the most important recent events in Gulf politics.

The evolution of universities' relations with the business sector in Brazil: What national publications between 1980 and 2012 reveal

ABSTRACT This paper addresses the changes in university-industry relations in Brazil regarding innovation activities. It is based on a survey of articles published in major national journals or presented at the most relevant Brazilian and regional conferences, between 1980 and 2012. The year 1980 was chosen due to the creation of the Technological Innovation Offices (NITs), which was the first government initiative to encourage knowledge transfer from universities to companies; the second was the Innovation Act of 2004. Our assumption was that after the Act the number of academic papers on this subject would increase, bringing new ideas and propositions of models to enhance this relationship. The methodology employed a qualitative, exploratory approach, using bibliographical research and a bibliometric analysis of 247 papers. Literature review of international studies shows the discussion of problems and suggestions for improvements, while in Brazil there is still a debate on whether this collaboration should occur, and if this is a legitimate role for the university. Despite the numerical growth, the content analysis showed few papers on new configurations and procedures for partnership management. We conclude that university-industry relations are not a regular and totally accepted process in Brazilian public universities, which reflect an ideological bias against cooperation with firms.
