We have described the existence of asymptomatic carriers of Plasmodium vivax and Plasmodium falciparum infections in native Amazon populations. Most of them had low parasitemias, detected only by polymerase chain reaction (PCR). Because they remain symptomless and untreated, we wanted to determine whether they could infect Anopheles darlingi Root, the main Brazilian vector, and act as disease reservoirs. Fifteen adult asymptomatic patients (PCR positive only) were selected, and experimental infections of mosquitoes were performed by direct feeding and by a membrane-feeding system. Seventeen adult symptomatic patients with high parasitemias were used as controls. We found an infection rate in An. darlingi of 1.2% for the asymptomatic carriers and 22% for the symptomatic carriers. Although the asymptomatic group infected mosquitoes at a much lower rate, these patients remain infective longer than treated, symptomatic patients. Also, the prevalence of asymptomatic infections is 4 to 5 times higher than symptomatic infections among natives. These results have implications for the malaria control program in Brazil, which focuses essentially on the treatment of symptomatic patients. © 2005 Entomological Society of America.

The Corumbau Marine Extractive Reserve was created in a region of rich biodiversity, located in the South of Bahia State, Brazil, to meet the revindications of artisanal fishermen in a context of increasing predatory industrial fisheries. The aim of the Marine Extractive Reserve is to improve the sustainability of fisheries stocks and the economy of artisanal fishermen's families, protecting the local biodiversity for the locals' collective use. However, at Corumbau the natives are facing social problems that have increased due to tourism growth. The present research contributes to the Management Plan in sectors that are crucial to assess the aspirations and subjective aspects related to the natives' daily life at individual, familiar and communitary levels. The Participatory Appraisal with a Gender Equity Perspective (PAGP) was applied to five communities at RESEX Corumbau, showing, by gender, the greatest problems artisanal fisheries' families are facing. Tourism is growing in the area, reflecting the residents different and contradictory interests. It can develop commerce and jobs, but also intensify some social and environmental problems in this area. © Society for Human Ecology.

The digital divide exacerbates inequalities in access to information and knowledge, making it more difficult to socialize with peers and limiting awareness of and the ability to use basic tools for life in society. Reducing this gap sets in motion virtuous synergies of social and cultural inclusion for children and adolescents, facilitating skills development and generating lifelong opportunities. Although the younger generations are connected digital natives, inequalities persist among socioeconomic groups, though these have been tempered by connectivity programmes in public schools in the region. The main article of this edition of Challenges uses current information to examine the progress made and the gaps that remain in this area. Providing children and adolescents with access is merely a first step. They then need to be protected from the risks associated with information and communications technologies (ICTs), which must be harnessed for purposes of meaningful learning, promoting uses that are more in line with the educational curriculum. Lastly, the article posits that connectivity policies must be linked to the fulfilment of children’s rights in the framework of the Convention on the Rights of the Child. As is customary, this issue also contains information on meetings and conferences held in the region during the year and recent publications in this field. Mention is also made of good practices from Peru in reducing gender gaps and a joint initiative between mobile operators and the United Nations Children’s Fund (UNICEF) to protect children in the digital age. Viewpoints includes expert opinion on the potential of ICTs as tools that can facilitate the exercise of the rights of children and adolescents, but also lead to violations of these rights.

Durante o governo da Ditadura Militar, a Amazônia se tornou parte do projeto de prioridades para ajudar o Brasil a alcançar um desenvolvimento maior. O Pará teve nesse processo grande destaque por ser o ‘portal de entrada da região’. Assim, boa parte dos empreendimentos que foram implantados neste estado, não levava em consideração a população que habitava esta longínqua parte do Brasil, há muito esquecida pelos governos federais. Os projetos pensados eram totalmente opostos ao tipo de atividades econômicas que durante séculos se trabalhava na região pelas comunidades existentes, como dos indígenas ou dos colonos. Os projetos agroindustriais tinham como meta a apropriação de grandes quantidades de terra para alcançarem seus objetivos. Com a concessão dos representantes militares, a Amazônia sofreu profundas mudanças depois da instalação desses agros negócios, fazendo com que muitas cidades que já existiam vivessem uma fase de grandes conflitos para não permitirem que os projetos se instalassem simplesmente de acordo com a vontade desses empresários e que prejudicassem inúmeras famílias. O município de Moju vivenciou esse cenário. O processo de instalação das agroindústrias se iniciou ainda na década de 1970, mas foi na década de 1980 que os colonos viram-se ameaçados de perder suas terras para esses empreendimentos. Dessa forma, neste trabalho, analiso como se deu à entrada desses projetos, assim como a organização desses colonos e os enfrentamentos que tiveram durante todo este período e que fez com que com que este cenário se transformasse em “palco de guerra” durante vários momentos. Os documentos utilizados como dossiê, reportagem de jornais, atas de reuniões, reportagem de revistas, entrevistas de lideranças sindicais, lavradores, vitimas da violência, ajudam a entender como se deu este processo turbulento na pequena cidade, que a todo custo deveria chegar ao ‘desenvolvimento econômico’.
