Detection of the pandemic norovirus variant GII.4 Sydney 2012 in Rio Branco, state of Acre, northern Brazil

Noroviruses (NoVs) are important cause of gastroenteritis in humans worldwide. Genotype GII.4 is responsible for the majority of outbreaks reported to date. This study describes, for the first time in Brazil, the circulation of NoV GII.4 variant Sydney 2012 in faecal samples collected from children aged less than or equal to eight years in Rio Branco, state of Acre, northern Brazil, during July-September 2012.

Acute Chagas disease in El Salvador 2000-2012 - Need for surveillance and control

Several parasitological studies carried out in El Salvador between 2000-2012 showed a higher frequency of acute cases of Chagas disease than that in other Central American countries. There is an urgent need for improved Chagas disease surveillance and vector control programs in the provinces where acute Chagas disease occurs and throughout El Salvador as a whole.

Incipient colonisation of Lutzomyia longipalpis in the city of Resistencia, province of Chaco, Argentina (2010-2012)

Lutzomyia longipalpis was recorded for the first time in Argentina in 2004, in the province of Formosa. In the following years, the vector spread to the south and west in the country and was recorded in the province of Chaco in 2010. From November 2010-May 2012, captures of Phlebotominae were made in the city of Resistencia and its surroundings, to monitor the spread and possible colonisation of Lu. longipalpis in the province of Chaco. In this monitoring, Lu. longipalpis was absent in urban sampling sites and its presence was restricted to Barrio de los Pescadores. This suggests that the incipient colonisation observed in 2010 was not followed by continuous installation of vector populations and expansion of their spatial distribution as in other urban centres of Argentina.

Effect of investments on fundamentals and market reaction on pre-operational and operational Brazilian companies for the period 2006-2012

ABSTRACT This paper provides evidence on the market reaction to corporate investment decisions whose shareholder value is largely attributed to growth options. The exploratory research raised pre-operational companies and their operational pairs on the same economy segments. It had the purpose of investigating the existence of statistical differentiation from financial indicators that reflect the installed assets and growth assets, and then study the market reaction to changes in fixed assets as a signaling element about investment decisions. The formation process of operational assets and shareholder value almost exclusively dependent on asset growth stands out in the pre-operational companies. As a result, differentiation tests confirmed that the pre-operational companies had their value especially derived on growth options. The market reaction was particularly bigger in pre-operational companies with abnormal negative stock returns, while the operational companies had positive returns, which may indicate that the quality of the investment is judged based on the financial disclosure. Additionally, operational companies' investors await the disclosure to adjust their prices. We conclude that the results are consistent with the empirical evidence and the participants in financial markets to long-term capital formation investments should give that special attention.

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.

Avaliação do potencial erosivo das chuvas em Urussanga, SC, no período de 1980 a 2012

O conhecimento do potencial erosivo das chuvas e a sua distribuição ao longo do ano contribuem para o planejamento de práticas de manejo e a conservação do solo, que visam a redução da erosão hídrica, diminuindo as perdas de solo e aumentando a produção agrícola. Este trabalho teve como objetivo caracterizar as chuvas da região de Urussanga, SC, com relação ao potencial erosivo, determinando os Índices de Erosividade mensais e anuais (EI30) e estabelecendo assim o fator "R" para utilização na Equação Universal de Perdas de Solo, período de retorno e probabilidade de ocorrência das chuvas erosivas, a partir dos dados de chuva de diagramas diários do pluviógrafo da Estação Meteorológica de Urussanga, de outubro de 1980 a março de 2012. As chuvas foram digitalizadas em segmentos com intensidade constante. Foi elaborado um programa computacional para a leitura dos dados digitalizados, identificação das chuvas erosivas e realização dos cálculos de erosividade. A precipitação pluvial média anual foi de 1.781,8 mm, dos quais 1.502,6 mm foram de chuvas erosivas e 279,1 mm, de não erosivas. Ocorrem em média 184,9 chuvas por ano, sendo 77,7 % não erosivas e 22,3 %, erosivas. O valor médio anual do índice EI30 é 5.665,10 MJ mm ha-1 h-1, classificando as chuvas com erosividade média a forte. A época do ano com maior erosividade é de dezembro a março. O fator "R" da USLE, para regiões do entorno com características semelhantes de Urussanga, pode ser estimado com dados de pluviometria utilizando-se a equação linear ajustada.
