A challenge in establishing agroforestry systems is ensuring that farmers are interested in the tree species, and are aware of how to adequately manage these species. This challenge was tackled in the Atlantic Rainforest biome (Brazil), where a participatory trial with agroforestry coffee systems was carried out, followed by a participatory systematisation of the farmers experiences. Our objective was to identify the main tree species used by farmers as well as their criteria for selecting or rejecting tree species. Furthermore, we aimed to present a specific inventory of trees of the Leguminosae family. In order to collect the data, we reviewed the bibliography of the participatory trial, visited and interviewed the farmers and organised workshops with them. The main farmers' criteria for selecting tree species were compatibility with coffee, amount of biomass, production and the labour needed for tree management. The farmers listed 85 tree species; we recorded 28 tree species of the Leguminosae family. Most trees were either native to the biome or exotic fruit trees. In order to design and manage complex agroforestry systems, family farmers need sufficient knowledge and autonomy, which can be reinforced when a participatory methodology is used for developing on-farm agroforestry systems. In the case presented, the farmers learned how to manage, reclaim and conserve their land. The diversification of production, especially with fruit, contributes to food security and to a low cost/benefit ratio of agroforestry systems. The investigated agroforestry systems showed potential to restore the degraded landscape of the Atlantic Rainforest biome.

BackgroundSkin infections are a common public health problem in developing countries; however, they are rarely managed using a population based approach. Recent data on the burden of skin infections in Timor-Leste are limited. Our survey appears to be the only widespread survey conducted in more than 30 years and was designed to determine the baseline prevalence of some common skin infections in Timor-Leste.MethodsWe conducted a cross sectional survey in 14 sites including community health clinics, schools and hospitals within four different geographical regions. Participants were examined for five conditions (scabies, pyoderma, fungal infections, leprosy and yaws) by a multidisciplinary team. Analyses were conducted using EpiInfo version 6.04d.ResultsWe examined the skin of 1535 participants aged between four months and 97 years. The majority of participants were male, aged between 11 and 20 years and had at least one condition of interest (56.0%, 56.0%, and 63.1%, respectively). Fungal infections were the most common presentation (39.0%) and males were more commonly affected than females (42.3% vs 34.0%, respectively, pvalue < 0.0001).Among those people with more than one condition the two most common co-infections were scabies with either pyoderma or a fungal infection (38.0% and 32.0%, respectively). The survey identified 29 previously undiagnosed cases of leprosy and six cases of yaws.ConclusionsOur findings indicate the need for a comprehensive programme to address these conditions. There are successful disease control programmes in place within the country and it is hoped a healthy skin programme could be integrated into an established disease control programme in order to maximise health benefits and resources.

ResumoO trabalho apresenta a riqueza de Leguminosae utilizada por 21 agricultores tradicionais em sistemas agroflorestais (SAFs) cafeeiros e fragmentos florestais na Floresta Atlântica, município de Araponga, Minas Gerais, Brasil, e as categorias de uso, importância relativa e similaridade das espécies entre os SAFs. Os dados foram obtidos através de entrevistas semiestruturadas e observação participante, entre agosto de 2005 e novembro de 2006, durante caminhadas direcionadas em sete SAFs e fragmentos florestais no entorno do Parque Estadual da Serra do Brigadeiro. Os agricultores citaram 59 espécies de Leguminosae; 86% são nativas da Floresta Atlântica, utilizadas em práticas culturais antigas, como para fazer carro de boi. Foram estabelecidas 12 categorias de uso, das quais as mais importantes foram adubo e lenha (21 spp cada). Nos SAFs, as espécies que adubam o solo (18 spp) são as mais utilizadas, e na floresta, para lenha e tecnologia (17 spp). O índice de importância relativa mostrou que na floresta, Piptadenia gonoacantha apresentou 83% de concordância quanto ao uso da madeira para cercar pastagem, enquanto nos SAFs, Inga edulis obteve 100% como alimento. Os SAFs estudados apresentam pouca similaridade em espécies (0,42 da escala Sorensen), devido à capacidade de seleção dos agricultores, proporcionando então, espaços para a conservação de espécies úteis de Leguminosae. Palavras-chave: Fabaceae, sistemas agroflorestais, botânica econômica, uso e conservação. AbstractThis study describes the richness of Leguminosae used by 21 traditional farmers in coffee agroforestry systems (AFS) and forest fragments of the Atlantic Forest, in the municipality of Araponga, Minas Gerais, Brazil. It also presents the use categories, relative importance and the species similarity between the AFSs. Data were collected through semi-structured interviews and participant observation, between August 2005 and November 2006, directed during random walks in seven AFSs and forest fragments surrounding the State Park of Serra do Brigadeiro. The farmers cited 59 species of Leguminosae, of which 86% are native to the Atlantic Forest and used in ancient cultural practices, such as to make bullock carts. Twelve categories of use were established, among them the most important were fertilizer and firewood (21 spp each); in the AFSs, species used for soil fertilization (18 spp) are the most utilized, and in the forest, the species for firewood and technology (17 spp.) The relative importance index showed that in the forest, Piptadenia gonoacantha showed 83% of agreement for the use as wood for fencing pastures, while in the AFSs, Inga edulis scored 100% as food. The AFSs studied show little similarity of species (0.42 of the Sorensen scale), due to the selection promoted by the farmers, thus, providing room for the conservation of useful species of Leguminosae.

Purpose Recent studies have shown that people who attend electronic dance music events and use drug checking services (DCS) are a predominantly white male, highly educated middle-class population. However, there is still a lack of data beyond sociodemographic characteristics that must be addressed. This paper aims to describe the drug use patterns and protective behavior strategies (PBS) used by testers and nontesters at Boom Festival 2018 and analyze the relationship between these behaviors and the decision to use the DCS. Design/methodology/approach This is an exploratory research based on a cross-sectional design using baseline data collected at the Boom Festival from testers (N = 343) and nontesters (N = 115). Findings Nontesters presented, in general, slightly higher frequencies of use for most drugs, whereas testers tended to adopt PBS more frequently. Moreover, testers planned their drug use more often than nontesters and set more limits on the amount of drugs they used in one session. Both of these behaviors work as predictors for using the DCS. Practical implications Our data suggest that DCS might not be easily accessible to all people who use drugs, reaching almost exclusively highly educated people that already apply several harm reduction strategies. Actions should be taken to promote service accessibility. Originality/value To the best of the authors’ knowledge, this paper is the first to compare the demographics, drug use and PBS adoption of DCS users with nonusers who attended the same festival.

-(Leguminosae in fragments of seasonal semideciduous forest, Araponga, MG: trees and lianas). A total of 26 species distributed in 12 genera and seven tribes were sampled in two fragments of seasonal forest during the period of one year. The subfamily Papilionoideae was the most represented with 11 species, five of which belong to genus Machaerium. The tribes Dalbergieae (10 spp.) and Ingeae (5 spp.) comprised 58% of species, among them, Dalbergia nigra (Vell.) Allemão ex Benth. are included in the endangered species list, and Abarema obovata (Benth.) Barneby & J.W. Grimes, whose distribution is limited to the State of Minas Gerais. The study presents analytical key, description and illustrations of species, flowering and fruiting times, as well as geographical distribution.

ResumenSe presenta un estudio sobre el uso de prácticas de gestión, que pueden ser calificadas como prácticas de gestión del conocimiento, en el Centro Tecnológico del Ejército CTEx, una institución pública de investigación en Brasil. Para ello, se aplicó un cuestionario dividido en tres partes: la primera investiga los antecedentes académicos de los miembros de la institución en especial si tenía algún tipo de formación en gestión; la segunda formada por un conjunto de veinte preguntas referidas a las diferentes prácticas de gestión existentes en la institución; y la tercera en que se plantea una pregunta abierta sobre una de estas prácticas de gestión y que ellos consideran de especial importancia. Los resultados mostraron que el CTEx no posee un plan estructurado de gestión y además no aplica en forma adecuada la mayoría de las mencionadas prácticas de gestión.Palabras clave: prácticas de gestión, gestión del conocimiento, diagnóstico de la gestión, gestión pública Abstract This paper presents a study on the use of management practices, which can be classified as knowledge management practices, at the Technological Center of the Army, CTEx, a public research institution in Brazil. For this, a questionnaire divided into three parts was applied: the first part investigates the academic background of the members of the institution, especially inquiring about previous training in management they might have; the second part consisted of a set of twenty questions related to the different management practices existing in the institution; and the third part that included an open question about one of the existing practices that they considered that deserve special attention. The results showed that the CTEx not only does not have a structured management plan but also it does not properly apply most of the existing management practices.

RESUMO O gênero Senna Mill. possui distribuição Pantropical e está representado por 300 espécies, dentre elas, 80 no Brasil e 22 em Mato Grosso. O gênero é reconhecido principalmente pela presença de nectários entre os folíolos na maioria das espécies, anteras basifixas e poricidas, ausência de bractéolas e também pelos legumes deiscentes ou raramente indeiscentes. O objetivo foi apresentar uma contribuição taxonômica das espécies Senna bacillaris (L.f.) H.S.Irwin & Barneby e S. cana (Nees & Mart.) H.S. Irwin & Barneby para a flora de Mato Grosso a partir do estudo taxonômico das novas ocorrências depositadas no Herbário da Amazônia Meridional (HERBAM). O trabalho foi realizado entre março e junho de 2016, a partir da análise morfológica das exsicatas de Senna depositadas no HERBAM. O HERBAM possui exsicatas de 15 espécies de Senna, todas coletadas em Mato Grosso, dentre elas, S. bacillaris e S. cana não citadas para o Estado no site Flora do Brasil. S. bacillaris foi coletada no município de Paranaíta. Todas as folhas tem nectários entre os pares de folíolos, estreitamente piriformes, folíolos 2 pares, 5,5-6,5x3-4 cm. S. cana foi coletada no município de Alta Floresta e possui nectários entre todos os pares de folíolos, cônicos, folíolos 4-8 pares, 4,2-6,9x1,8-2,2 cm. Os caracteres de S. bacillaris foram mais consistentes conforme a descrição da última revisão do gênero, enquanto que, S. cana, apresentou maior variação morfológica em relação aos nectários extraflorais. O trabalho reforça a ampliação de 22 para 24 espécies de Senna para a Flora de Mato Grosso.
