This book presents data and discusses the results of research conducted on crack cocaine consumption and other drug use in the city of São Paulo, Brazil, specifically in the area commonly referred to as \"Cracolândia\" (\"Crackland\"). This context is marked by high social vulnerability, rife with numerous inequalities, violence, and human rights violations. The work describes the living conditions of individuals in this setting, narrating their social trajectories, urban itineraries, motivations for substance use, perspectives, and life projects.The book provokes a crucial debate concerning the iatrogenic effects resulting from prohibitionist-repressive \"war on drugs\" policies. It highlights potential alternative paths for formulating and implementing public policies and psychosocial interventions.'Amidst the Flow' serves as a valuable resource for researchers and professionals in the fields of addiction studies, healthcare, sociology, law, and drug policy-making. It presents a compelling call for a paradigm shift in drug policies.

A detailed account is given of the history, aetiology, biology, epidemiology, detection, geographical distribution, and control of huanglongbing (HLB), a destructive disease of citrus that represents a major threat to the world citrus industry, and is slowly invading new citrusgrowing areas. HLB, whose name in Chinese means \"yellow dragon disease\", was first reported from southern China in 1919 and is now known to occur in next to 40 different Asian, African, Oceanian, South and North American countries. The agent is a phloem-restricted, non cultured, Gram-negative bacterium causing crippling diseases denoted \"greening\" in South Africa, \"mottle leaf\" in the Philippines, \"dieback\" in India, \"vein phloem degeneration\" in Indonesia. The HLB bacterium belongs to the genus Candidatus Liberibacter, three species of which are currently known, Candidatus Liberibacter asiaticus, occurring in Asian countries and, to a lesser extent, in Brazil and the USA (Florida), Candidatus Liberibacter africanus with its subspecies \"capensis\", recorded from African countries, and Candidatus Liberibacter americanus present in Brazil. The suggestion is that each liberibacter species has evolved in the continent after which it is named. HLB symptoms are virtually the same wherever the disease occurs. Infected trees show a blotchy mottle condition of the leaves that results in the development of yellow shoots, the early and very characteristic symptom of the disease. Trees are stunted, declining and bear a few, small-sized, and deformed (lop-sided) fruits, that are poorly coloured (greening) and with coloration starting at the peduncular end (colour inversion). HLB can be transmitted by grafting from citrus to citrus and by dodder to periwinkle. The psyllids Trioza erytreae and Diaphorina citri are natural vectors. Two different types of HLB are known: the heat-sensitive African form transmitted by T. erytreae, which develops at temperatures of 22-25°C, and the heat-tolerant Asian form, transmitted by D. citri, which stands temperatures well above 30°C. Although the HLB pathogen can be identified by electron microscopy, other laboratory methods are used for routine detection. ELISA with monoclonal antibodies is not recommended. Better systems are dot blot hybridization with a DNA probe, and various PCR formats (one-step, nested, multiplex) using species-specific primers based on 16S rRNA or rplKAJL-rpoBC operon sequences. Because no curative methods of HLB are available, control is preventive and largely based on inoculum elimination by removal of infected trees and chemical treatments against vectors. Strict quarantine measures must be implemented to impair further international spread of HLB agents and their vectors.

O documentário do diretor brasileiro evoca o percurso do filme que o cineasta russo Mikhail Kalatozov fez em Cuba em 1962. O filme frustrou o público na URSS e em Cuba porque se concentra numa dimensão estética. Foi resgatado nos anos 1990. Le documentaire du réalisateur brésilien Vicente Ferraz Soy Cuba : o mamute siberiano s'attache à éclairer la trajectoire du film que le réalisateur russe Mikhail Kalatozov tourna à Cuba en 1962. Mal compris à sa sortie, tant en URSS qu'à Cuba, à cause de sa dimension esthétique , il fut réhabilité dans les années 1990.

Doña Marina (La Malinche) ...Pocahontas ...Sacagawea-their names live on in historical memory because these women bridged the indigenous American and European worlds, opening the way for the cultural encounters, collisions, and fusions that shaped the social and even physical landscape of the modern Americas. But these famous individuals were only a few of the many thousands of people who, intentionally or otherwise, served as \"go-betweens\" as Europeans explored and colonized the New World. In this innovative history, Alida Metcalf thoroughly investigates the many roles played by go-betweens in the colonization of sixteenth-century Brazil. She finds that many individuals created physical links among Europe, Africa, and Brazil-explorers, traders, settlers, and slaves circulated goods, plants, animals, and diseases. Intercultural liaisons produced mixed-race children. At the cultural level, Jesuit priests and African slaves infused native Brazilian traditions with their own religious practices, while translators became influential go-betweens, negotiating the terms of trade, interaction, and exchange. Most powerful of all, as Metcalf shows, were those go-betweens who interpreted or represented new lands and peoples through writings, maps, religion, and the oral tradition. Metcalf's convincing demonstration that colonization is always mediated by third parties has relevance far beyond the Brazilian case, even as it opens a revealing new window on the first century of Brazilian history.

Ambition theory suggests that scholars can understand a good deal about politics by exploring politicians' career goals. In the USA, an enormous literature explains congressional politics by assuming that politicians primarily desire to win re-election. In contrast, although Brazil's institutions appear to encourage incumbency, politicians do not seek to build a career within the legislature. Instead, political ambition focuses on the subnational level. Even while serving in the legislature, Brazilian legislators act strategically to further their future extra-legislative careers by serving as 'ambassadors' of subnational governments. Brazil's federal institutions also affect politicians' electoral prospects and career goals, heightening the importance of subnational interests in the lower chamber of the national legislature. Together, ambition and federalism help explain important dynamics of executive-legislative relations in Brazil. This book's rational-choice institutionalist perspective contributes to the literature on the importance of federalism and subnational politics to understanding national-level politics around the world.

Anthropologists widely agree that identities--even ethnic and racial ones--are socially constructed. Less understood are the processes by which social identities are conceived and developed.Legalizing Identitiesshows how law can successfully serve as the impetus for the transformation of cultural practices and collective identity. Through ethnographic, historical, and legal analysis of successful claims to land by two neighboring black communities in the backlands of northeastern Brazil, Jan Hoffman French demonstrates how these two communities have come to distinguish themselves from each other while revising and retelling their histories and present-day stories.French argues that the invocation of laws by these related communities led to the emergence of two different identities: one indigenous (Xoco Indian) and the other quilombo (descendants of a fugitive African slave community). With the help of the Catholic Church, government officials, lawyers, anthropologists, and activists, each community won government recognition and land rights, and displaced elite landowners. This was accomplished even though anthropologists called upon to assess the validity of their claims recognized that their identities were \"constructed.\" The positive outcome of their claims demonstrates that authenticity is not a prerequisite for identity. French draws from this insight a more sweeping conclusion that, far from being evidence of inauthenticity, processes of construction form the basis of all identities and may have important consequences for social justice.

Few studies have assessed effects of habitat fragmentation on tropical forest dynamics. We describe results from an 18-yr experimental study of the effects of rain forest fragmentation on tree-community dynamics in central Amazonia. Tree communities were assessed in 39 permanent, 1-ha plots in forest fragments of 1, 10, or 100 ha in area, and in 27 plots in nearby continuous forest. Repeated censuses of >56 000 marked trees (≥ 10 cm diameter at breast height) were used to generate annualized estimates of tree mortality, damage, and turnover in fragmented and continuous forest. On average, forest fragments exhibited markedly elevated dynamics, apparently as a result of increased windthrow and microclimatic changes near forest edges. Mean mortality, damage, and turnover rates were much higher within 60 m of edges (4.01, 4.10, and 3.16%, respectively) and moderately higher within 60-100 m of edges (2.40, 1.96, and 2.05%) than in forest interiors (1.27, 1.48, and 1.15%). Less-pronounced changes in mortality and turnover rates were apparently detectable up to ∼ 300 m from forest edges. Edge aspect had no significant effect on forest dynamics. Tree mortality and damage rates did not vary significantly with fragment age, suggesting that increased dynamics are not merely transitory effects that occur immediately after fragmentation, while turnover rates increased with age in most (8/9) fragments. These findings reveal that fragmentation causes important changes in the dynamics of Amazonian forests, especially within ∼ 100 m of habitat edges. A mathematical \"core-area model\" incorporating these data predicted that edge effects will increase rapidly in importance once fragments fall below ∼ 100-400 ha in area, depending on fragment shape. Accelerated dynamics in fragments will alter forest structure, floristic composition, biomass, and microclimate and are likely to exacerbate effects of fragmentation on disturbance-sensitive species.
