Patterns of resistance to angular leaf spot, anthracnose and common bacterial blight in common bean germplasm

Diseases and insect pests are major causes of low yields of common bean (Phaseolus vulgaris L.) in Latin America and Africa. Anthracnose, angular leaf spot and common bacterial blight are widespread foliar diseases of common bean that also infect pods and seeds. One thousand and eighty-two accessions from a common bean core collection from the primary centres of origin were investigated for reaction to these three diseases. Angular leaf spot and common bacterial blight were evaluated in the field at Santander de Quilichao, Colombia, and anthracnose was evaluated in a screenhouse in Popayan, Colombia. By using the 15-group level from a hierarchical clustering procedure, it was found that 7 groups were formed with mainly Andean common bean accessions (Andean gene pool), 7 groups with mainly Middle American accessions (Middle American gene pool), while 1 group contained mixed accessions. Consistent with the theory of co-evolution, it was generally observed that accessions from the Andean gene pool were resistant to Middle American pathogen isolates causing anthracnoxe, while the Middle American accessions were resistant to pathogen isolates from the Andes. Different combinations of resistance patterns were found, and breeders can use this information to select a specific group of accessions on the basis of their need.

Genetic variability in cultivated common bean beyond the two major gene pools

It is generally accepted that two major gene pools exist in cultivated common bean (Phaseolus vulgaris L.), a Middle American and an Andean one. Some evidence, based on unique phaseolin morphotypes and AFLP analysis, suggests that at least one more gene pool exists in cultivated common bean. To investigate this hypothesis, 1072 accessions from a common bean core collection from the primary centres of origin, held at CIAT, were investigated. Various agronomic and morphological attributes (14 categorical and 11 quantitative) were measured. Multivariate analyses, consisting of homogeneity analysis and clustering for categorical data, clustering and ordination techniques for quantitative data and nonlinear principal component analysis for mixed data, were undertaken. The results of most analyses supported the existence of the two major gene pools. However, the analysis of categorical data of protein types showed an additional minor gene pool. The minor gene pool is designated North Andean and includes phaseolin types CH, S and T; lectin types 312, Pr, B and K; and mostly A5, A6 and A4 types alpha-amylase inhibitor. Analysis of the combined categorical data of protein types and some plant categorical data also suggested that some other germplasm with C type phaseolin are distinguished from the major gene pools.

Turkey's Accession to the European Union in terms of impact on the EU's security and defense policies: potential and drawbacks

This study explores the impact of Turkey's likely entry in the European Union (EU) in terms of the EU's foreign, security and defense policies. It reviews Turkish capabilities, namely its military capabilities, which could provide the EU with valuable defense assets. There are differences related to Turkey's relations with the EU, which have increasingly spilled over into the NATO, hindering the development of cooperation over crisis management operations. The article then delves in the implications of Turkey's strategic geographical location to EU policies. It reviews how far the EU and Turkey may have convergent interests in some of the neighboring regions, especially in the Middle East.

D. José da Costa Nunes - A Patriarch who cared for more than souls: A case of caesaro-papism in Portuguese India, 1942-1953

É pouco conhecido que durante vários séculos e até ao fim do colonialismo português no Oriente seguiu-se a prática de enviar bispos açorianos. Eram brancos e não tinham outra língia e cultura que não fossem portuguesas. Eram critérios suficientes para serem preferidos a candidatos asiáticos mesmo com formação superior e conhecedores das línguas e culturas dos seus povos. Desconfiava-se da sua lealdade e patriotismo. Isto era particularmente crucial quando se iniciaram movimentos independentistas na Ásia. D. José da Costa Nunes é estudado neste ensaio como um paradigma desta política colonial.

Instrumentos e mecanismos de gestão: contribuições ao processo decisório em conselhos de políticas públicas

A administração pública no Brasil conta com diretrizes e parâmetros estabelecidos em documentos, a exemplo de leis, políticas ou planos, que se constituem em instrumentos para nortear e qualificar a gestão democrática das políticas públicas. A investigação buscou identificar instrumentos e mecanismos de gestão utilizados no processo decisório pelos Conselhos Municipais de Assistência Social e de Saúde em Chapecó (SC). A partir da leitura de atas (2005 a 2009), obtiveram-se como instrumento mais citado os relatórios de prestação de contas, embora esses não evidenciarem articulação com objetivos e metas definidos no plano municipal. Os mecanismos mais utilizados são comissões internas, capacitação, conferências e comunicação com outras organizações. Os conselhos estudados recorrem a instrumentos e mecanismos com potencial para ampliar a participação na gestão pública municipal.

Prevalence of hypertension among adolescents: systematic review and meta-analysis

ABSTRACT OBJECTIVE To estimate the prevalence of hypertension among adolescent Brazilian students. METHODS A systematic review of school-based cross-sectional studies was conducted. The articles were searched in the databases MEDLINE, Embase, Scopus, LILACS, SciELO, Web of Science, CAPES thesis database and Trip Database. In addition, we examined the lists of references of relevant studies to identify potentially eligible articles. No restrictions regarding publication date, language, or status applied. The studies were selected by two independent evaluators, who also extracted the data and assessed the methodological quality following eight criteria related to sampling, measuring blood pressure, and presenting results. The meta-analysis was calculated using a random effects model and analyses were performed to investigate heterogeneity. RESULTS We retrieved 1,577 articles from the search and included 22 in the review. The included articles corresponded to 14,115 adolescents, 51.2% (n = 7,230) female. We observed a variety of techniques, equipment, and references used. The prevalence of hypertension was 8.0% (95%CI 5.0–11.0; I2 = 97.6%), 9.3% (95%CI 5.6–13.6; I2 = 96.4%) in males and 6.5% (95%CI 4.2–9.1; I2 = 94.2%) in females. The meta-regression failed to identify the causes of the heterogeneity among studies. CONCLUSIONS Despite the differences found in the methodologies of the included studies, the results of this systematic review indicate that hypertension is prevalent in the Brazilian adolescent school population. For future investigations, we suggest the standardization of techniques, equipment, and references, aiming at improving the methodological quality of the studies.

ERICA: prevalence of common mental disorders in Brazilian adolescents

ABSTRACT OBJECTIVE To describe the prevalence of common mental disorders in Brazilian adolescent students, according to geographical macro-regions, school type, sex, and age. METHODS We evaluated 74,589 adolescents who participated in the Cardiovascular Risk Study in Adolescents (ERICA), a cross-sectional, national, school-based study conducted in 2013-2014 in cities with more than 100,000 inhabitants. A self-administered questionnaire and an electronic data collector were employed. The presence of common mental disorders was assessed using the General Health Questionnaire (GHQ-12). We estimated prevalence and 95% confidence intervals of common mental disorders by sex, age, and school type, in Brazil and in the macro-regions, considering the sample design. RESULTS The prevalence of common mental disorders was of 30.0% (95%CI 29.2-30.8), being higher among girls (38.4%; 95%CI 37.1-39.7) when compared to boys (21.6%; 95%CI 20.5-22.8), and among adolescents who were from 15 to 17 years old (33.6%; 95%CI 32.2-35.0) compared to those aged between 12 and 14 years (26.7%; 95%CI 25.8-27.6). The prevalence of common mental disorders increased with age for both sexes, always higher in girls (ranging from 28.1% at 12 years to 44.1% at 17 years) than in boys (ranging from 18.5% at 12 years to 27.7% at 17 years). We did not observe any significant difference by macro-region or school type. Stratified analyses showed higher prevalence of common mental disorders among girls aged from 15 to 17 years of private schools in the North region (53.1; 95%CI 46.8-59.4). CONCLUSIONS The high prevalence of common mental disorders among adolescents and the fact that the symptoms are often vague mean these disorders are not so easily identified by school administrators or even by health services. The results of this study can help the proposition of more specific prevention and control measures, focused on highest risk subgroups.

SIR performance evaluation of MB-OFDM UWB system with residual timing offset

Signal-to-interference ratio (SIR) performance of a multiband orthogonal frequency division multiplexing ultra-wideband system with residual timing offset is investigated. To do so, an exact mathematical derivation of the SIR of this system is derived. It becomes obvious that, unlike a cyclic prefixing based system, a zero padding based system is sensitive to residual timing offset.

THE ISLAMIC POLICY OF PORTUGUESE COLONIAL MOZAMBIQUE, 1960-1973

Drawing its information from different documents in Portuguese and French archives, this article examines the evolution of Portuguese colonial policies regarding Islam, focusing the special case of Mozambique. Such policies evolved from an attitude of neglect and open repression, prevalent in the early years of the colonial war, when Muslims were perceived as main supporters of the anti-colonial guerrilla in northern Mozambique, to a more nuanced approach that tried to isolate ‘African Muslims’ from foreign influences in order to align them with the Portuguese combat against the anti-colonial movement. The article analyses the latter strategy, assessing its successes and failures and the contributions made by several actors that were engaged in this achievement: the Catholic Church, the core of political power and its local ramifications in the colonies.

Islão transnacional e os fantasmas do colonialismo português

Este artigo examina a forma como as políticas colónias portuguesas de enquadramento do Islão na Guiné e em Moçambique evoluíram de uma representação do muçulmano como ameaça para uma imagem mais conciliadora, pela qual os muçulmanos poderiam ser potenciais aliados do poder português na guerra contra os movimentos nacionalistas. Sendo ambas as representações marcadas pela ambivalência, a primeira predominou até ao final da década de 50 e a segunda desenhou-se em meados dos anos 60, acompanhando o restante trajecto das guerras coloniais. As duas imagens corresponderam a diferentes formas de lidar com a dimensão transnacional do Islão e com o seu alegado impacto sobre o colonialismo português em África. O artigo analisa essas estratégias, abordando a participação que nelas teve a Igreja Católica, o aparelho central de poder e as suas ramificações locais nas colónias.

Relações sinuosas: Portugal e o mundo árabe, 1950-1973

Nas três últimas décadas do colonialismo português, as políticas destinadas às populações muçulmanas da Guiné e de Moçambique passaram da hostilidade mais ou menos aberta para uma estratégia de sedução, com vista a promover um “Islão português” e a usar certos sectores muçulmanos no combate aos movimentos nacionalistas. Esta transição teve também uma componente transnacional, na medida em que se quis alargar a intervenção portuguesa a um espaço estratégico designado como “mundo islâmico”. O presente artigo procura analisar essa intervenção, debruçando-se sobre o pensamento geopolítico que a informou e as suas aplicações diplomáticas, em particular no relacionamento com os países árabes.

O ensino na política islâmica do Moçambique colonial: da ansiedade islamofóbica à miragem do ‘Islão português

Ao longo da trajectória colonial, a abordagem do Islão moçambicano pelas autoridades portuguesas passou de uma islamofobia renitente, por vezes com gestos esporádicos de aproximação, para um programa de sedução das lideranças islâmicas, desenvolvido entre 1968 e 1974. Partindo deste quadro evolutivo, o presente artigo procura traçar a transformação das políticas dedicadas ao ensino islâmico em Moçambique. Se o tempo islamofóbico viu nesse ensino um factor de “desnacionalização” da população colonizada, o período seguinte encarou-o como obstáculo à ideia de um “Islão português”, obstáculo que alguns pensaram contornar subordinando as escolas corânicas ao sistema oficial de ensino. O artigo analisa também as tensões suscitadas por estas políticas, focando a reacção de hostilidade por parte do meio católico mais conservador

The Islamic Policy of Portuguese Colonial Mozambique, 1960-1973

Drawing its information from different documents in Portuguese and French archives, this article examines the evolution of Portuguese colonial policies towards Islam, focusing on the special case of Mozambique. Such policies evolved from an attitude of neglect and open repression, prevalent in the early years of the colonial war that broke out in 1965, when Muslims were perceived as the main supporters of the anti-colonial guerrilla in northern Mozambique, to an approach that tried to isolate ‘African Muslims’ from foreign influences in order to align them with the Portuguese. The article analyses the latter strategy, assessing its successes and failures, and the contributions made by several of those who were involved.
