Imagens de África? Filmes e documentários portugueses relativos às antigas colónias africanas (primeira metade do século XX)

Este artigo analisa filmes e documentários, realizados em Portugal, que tiveram como pano de fundo as ex-colónias africanas ou nelas foram inspirados. Durante o Estado Novo, a defesa de uma boa imagem do “império” e da política colonial levou a proibir filmes que incluíssem maus-tratos a indivíduos de origem africana, ilustrassem a luta entre o “branco” (colono) e o “negro” (colonizado), retratassem os movimentos de luta pela ascensão dos negros nos EUA ou exaltassem aspetos pacifistas ou antimilitaristas. Muitos documentários destacam as potencialidades (naturais e humanas) de África. Alguns são dedicados à criação de estruturas de ensino e evangelização dos africanos, ou procuram retratar os seus “usos e costumes”. Outros evidenciam a força de trabalho do africano na construção de um futuro prometedor. Tal trabalho é orientado pelo “branco”, i.e., é ao saber técnico deste que se junta a força do africano. Os africanos são representados como exemplos de um conjunto uno (todos são denominados “indígenas”), mas entre eles procuram-se evidenciar características distintivas. As imagens que denotam modernização, em cidades como Luanda ou Lourenço Marques, ofuscam os “colonizados”. Estes filmes têm amiúde um carácter mais de propaganda do que informação, ou etnográfico, e têm como objetivo transmitir uma consciência colonial.

Langues/ religions/ systèmes scolaires : l'identité tchadienne et les apports de la France

Questo elaborato mira ad analizzare i rapporti tra la Francia, in quanto colonizzatore in Africa, e il Ciad e l'influenza da essa esercitata sul piano religioso,linguistico e culturale. In primis viene presentata la situazione linguistico-culturale del Ciad, diviso internamente tra Nord e Sud. Poi vengono confrontati il sistema scolastico francese e quello arabo sia dal punto di vista dell'organizzazione che di partecipazione e importanza, e analizzate le conflittualità tra questi due sistemi. Infine, dopo essersi concentrati sui problemi dell'istruzione in Ciad, si dibatte sulla possibilità di risolvere le situazioni di conflitto che lo stato presenta.

Quo vadis Aethina tumida? Biology and control of small hive beetles

Small hive beetles (SHBs) are generalists native to sub-Saharan Africa and reproduce in association with honeybees, bumblebees, stingless bees, fruits and meat. The SHB has recently become an invasive species, and introductions have been recorded from America, Australia, Europe and Asia since 1996. hile SHBs are usually considered a minor pest in Africa, they can cause significant damage to social bee colonies in their new ranges. Potential reasons for differential impact include differences in bee behaviour, climate and release from natural enemies. Here, we provide an overview on biology, distribution, pest status, diagnosis, control and prevention to foster adequate mitigation and stimulate future research. SHBs have become a global threat to both apiculture and wild bee populations, but our knowledge of this pest is still limited, reating demand for more research in all areas of its biology.

Children and war

Children bear disproportionate consequences of armed conflict. The 21st century continues to see patterns of children enmeshed in international violence between opposing combatant forces, as victims of terrorist warfare, and, perhaps most tragically of all, as victims of civil wars. Innocent children so often are the victims of high-energy wounding from military ordinance. They sustain high-energy tissue damage and massive burns - injuries that are not commonly seen in civilian populations. Children have also been deliberately targeted victims in genocidal civil wars in Africa in the past decade, and hundreds of thousands have been killed and maimed in the context of close-quarter, hand-to-hand assaults of great ferocity. Paediatricians serve as uniformed military surgeons and as civilian doctors in both international and civil wars, and have a significant strategic role to play as advocates for the rights and welfare of children in the context of the evolving 'Laws of War'. One chronic legacy of contemporary warfare is blast injury to children from landmines. Such blasts leave children without feet or lower limbs, with genital injuries, blindness and deafness. This pattern of injury has become one of the post-civil war syndromes encountered by all intensivists and surgeons serving in four of the world's continents. The continued advocacy for the international ban on the manufacture, commerce and military use of antipersonnel landmines is a part of all paediatricians' obligation to promote the ethos of the Laws of War. Post-traumatic stress disorder remains an undertreated legacy of children who have been trapped in the shot and shell of battle as well as those displaced as refugees. An urgent, unfocused and unmet challenge has been the increase in, and plight of, child soldiers themselves. A new class of combatant comprises these children, who also become enmeshed in the triad of anarchic civil war, light-weight weaponry and drug or alcohol addiction. The International Criminal Court has outlawed as a War Crime, the conscription of children under 15 years of age. Nevertheless, there remain more than 300 000 child soldiers active and enmeshed in psychopathic violence as part of both civil and international warfare. The typical profile of a child soldier is of a boy between the ages of 8 and 18 years, bonded into a group of armed peers, almost always an orphan, drug or alcohol addicted, amoral, merciless, illiterate and dangerous. Paediatricians have much to do to protect such war-enmeshed children, irrespective of the accident of their place of birth. Only by such vigorous and maintained advocacy can the world's children be better protected from the scourge of future wars.

Phylogeny, molecular and fossil dating, and biogeographic history of Annonaceae and Myristicaceae (Magnoliales)

Annonaceae and Myristicaceae, the two largest families of Magnoliales, are pantropical groups of uncertain geographic history. The most recent morphological and molecular phylogenetic analyses identify the Asian-American genus Anaxagorea as sister to all other Annonaceae and the ambavioids, consisting of small genera endemic to South America, Africa, Madagascar, and Asia, as a second branch. However, most genera form a large clade in which the basal lines are African, and South American and Asian taxa are more deeply nested. Although it has been suggested that Anaxagorea was an ancient Laurasian line, present data indicate that this genus is basically South American. These considerations may mean that the family as a whole began its radiation in Africa and South America in the Late Cretaceous, when the South Atlantic was narrower, and several lines dispersed from Africa-Madagascar into Laurasia as the Tethys closed in the Tertiary. This scenario is consistent with the occurrence of annonaceous seeds in the latest Cretaceous of Nigeria and the Eocene of England and with molecular dating of the family. Based on distribution of putatively primitive taxa in Madagascar and derived taxa in Asia, it has been suggested that Myristicaceae had a similar history. Phylogenetic analyses of Myristicaceae, using morphology and several plastid regions, confirm that the ancestral area was Africa-Madagascar and that Asian taxa are derived. However, Myristicaceae as a whole show strikingly lower molecular divergence than Annonaceae, indicating either a much younger age or a marked slowdown in molecular evolution. The fact that the oldest diagnostic fossils of Myristicaceae are Miocene seeds might be taken as evidence that Myristicaceae are much younger than Annonaceae, but this is implausible in requiring transoceanic dispersal of their large, animal-dispersed seeds.

Sample registration of vital events with verbal autopsy: a renewed commitment to measuring and monitoring vital statistics

Registration of births, recording deaths by age, sex and cause, and calculating mortality levels and differentials are fundamental to evidence-based health policy, monitoring and evaluation. Yet few of the countries with the greatest need for these data have functioning systems to produce them despite legislation providing for the establishment and maintenance of vital registration. Sample vital registration (SVR), when applied in conjunction with validated verbal autopsy, procedures and implemented in a nationally representative sample of population clusters represents an affordable, cost-effective, and sustainable short- and medium-term solution to this problem. SVR complements other information sources by producing age-, sex-, and cause-specific mortality data that are more complete and continuous than those currently available. The tools and methods employed in an SVR system, however, are imperfect and require rigorous validation and continuous quality assurance; sampling strategies for SVR are also still evolving. Nonetheless, interest in establishing SVR is rapidly growing in Africa and Asia. Better systems for reporting and recording data on vital events will be sustainable only if developed hand-in-hand with existing health information strategies at the national and district levels; governance structures; and agendas for social research and development monitoring. If the global community wishes to have mortality measurements 5 or 10 years hence, the foundation stones of SVR must be laid today.

A simulation model of cereal-legume intercropping systems for semi-arid regions II. Model application

Smallholder farmers in Africa practice traditional cropping techniques such as intercropping. Intercropping is thought to offer higher productivity and resource milisation than sole cropping. In this study, risk associated with maize-bean intercropping was evaluated by quantifying long-term yield in both intercropping and sole cropping in a semi-arid region of South Africa (Bloemfontein, Free State) with reference to rainfall variability. The crop simulation model was run with different cultural practices (planting date and plant density) for 52 summer crop growing seasons (1950/1951-2001/2002). Eighty-one scenarios, consisted of three levels of initial soil water, planting date, maize population, and bean population, were simulated. From the simulation outputs, the total land equivalent ratio (LER) was greater than one. The intercrop (equivalent to sole maize) had greater energy value (EV) than sole beans, and the intercrop (equivalent to sole beans) had greater monetary value (MV) than sole maize. From these results, it can be concluded that maize-bean intercropping is advantageous for this semi-arid region. Soil water at planting was the most important factor of all scenario factors, followed by planting date. Irrigation application at planting, November/December planting and high plant density of maize for EV and beans for MV can be one of the most effective cultural practices in the study region. With regard to rainfall variability, seasonal (October-April) rainfall positively affected EV and MV, but not LER. There was more intercrop production in La Nina years than in El Nino years. Thus, better cultural practices may be selected to maximize maize-bean intercrop yields for specific seasons in the semi-arid region based on the global seasonal outlook. (c) 2004 Elsevier B.V.

Measuring the global burden of disease and epidemiological transitions: 2002-2030

Any planning process for health development ought to be based on a thorough understanding of the health needs of the population. This should be sufficiently comprehensive to include the causes of premature death and of disability, as well as the major risk factors that underlie disease and injury. To be truly useful to inform health-policy debates, such an assessment is needed across a large number of diseases, injuries and risk factors, in order to guide prioritization. The results of the original Global Burden of Disease Study and, particularly, those of its 2000-2002 update provide a conceptual and methodological framework to quantify and compare the health of populations using a summary measure of both mortality and disability: the disability-adjusted life-year (DALY). Globally, it appears that about 5 6 million deaths occur each year, 10. 5 million (almost all in poor countries) in children. Of the child deaths, about one-fifth result from perinatal causes such as birth asphyxia and birth trauma, and only slightly less from lower respiratory infections. Annually, diarrhoeal diseases kill over 1.5 million children, and malaria, measles and HIV/AIDS each claim between 500,000 and 800,000 children. HIV/AIDS is the fourth leading cause of death world-wide (2.9 million deaths) and the leading cause in Africa. The top three causes of death globally are ischaemic heart disease (7.2 million deaths), stroke (5.5 million) and lower respiratory diseases (3.9 million). Chronic obstructive lung diseases (COPD) cause almost as many deaths as HIV/AIDS (2.7 million). The leading causes of DALY, on the other hand, include causes that are common at young ages [perinatal conditions (7. 1 % of global DALY), lower respiratory infections (6.7%), and diarrhoeal diseases (4.7%)] as well as depression (4.1%). Ischaemic heart disease and stroke rank sixth and seventh, retrospectively, as causes of global disease burden, followed by road traffic accidents, malaria and tuberculosis. Projections to 2030 indicate that, although these major vascular diseases will remain leading causes of global disease burden, with HIV/AIDS the leading cause, diarrhoeal diseases and lower respiratory infections will be outranked by COPD, in part reflecting the projected increases in death and disability from tobacco use.

Molecular discrimination of taeniid cestodes :

DNA approaches are now being used routinely for accurate identification of Echinococcus and Taenia species, subspecies and strains, and in molecular epidemiological surveys of echinococcosis/taeniasis in different geographical settings and host assemblages. The publication of the complete sequences of the mitochondrial (int) genomes of E. granulosus, E. multilocularis, T solium and Asian Taenia, and the availability of mtDNA sequences for a number of other taeniid genotypes, has provided additional genetic information that can be used for more in depth phylogenetic and taxonomic studies of these parasites. This very rich sequence information has provided a solid molecular basis, along with a range of different biological, epidemiological, biochemical and other molecular-genetic criteria, for revising the taxonomy of the genus Echinococcus and for estimating the evolutionary time of divergence of the various taxa. Furthermore, the accumulating genetic data has allowed the development of PCR-based tests for unambiguous identification of Echinococcus eggs in the faeces of definitive hosts and in the environment. Molecular phylogenies derived from mtDNA sequence comparisons of geographically distributed samples of T solium provide molecular evidence for two genotypes, one being restricted to Asia, with the other occurring in Africa and America. Whether the two genetic forms of T solium differ in important phenotypic characteristics remains to be determined. As well, minor DNA sequence differences have been reported between isolates of T saginata and Asian Taenia. There has been considerable discussion over a number of years regarding the taxonomic position of Asian Taenia and whether it should be regarded as a genotype, strain, subspecies or sister species of T saginata. The available molecular genetic data do not support independent species status for Asian Taenia and T saginata. What is in agreement is that both taxa are closely related to each other but distantly related to T solium. This is important in public health terms as it predicts that cysticercosis in humans attributable to Asian Taenia does not occur, because cysticercosis is unknown in T saginata.

CONHECER PARA CONVERTER OU ALGO MAIS?: LEITURA CRÍTICA DAS ETNOGRAFIAS MISSIONÁRIAS DE HENRI-ALEXANDRE JUNOD E CARLOS ESTERMANN

Resumo: O colonialismo produziu diversos discursos sobre as culturas locais, sendo que o discurso dos missionários é uma de suas variantes e, por sua vez, neste discurso estão inclusas as etnografias missionárias. Apresentamos uma leitura crítica de duas etnografias missionárias produzidas nas até então colônias portuguesas, os territórios de Angola e Moçambique. A primeira, intitulada Usos e costumes dos bantos: a vida duma tribo sulafricana, cujo autor é o missionário Henri-Alexandre Junod (1863-1934); a segunda, intitulada Etnografia do sudoeste de Angola, cujo autor é o missionário Carlos Estermann (1896- 1976). Problematizamos a relação entre a ação missionária, o colonialismo português e as culturas locais dos territórios de Angola e Moçambique, através da análise destas etnografias missionárias. Destacamos que estas etnografias, além de apresentarem a riqueza das formas de vida das sociedades nativas, sinalizam como se efetivaram as negociações entre estes missionários em suas práticas de missionação e seus interlocutores nativos.

IGREJA UNIVERSAL DO REINO DE DEUS NA ÁFRICA SUBSAARIANA: IMPLANTAÇÃO, EXPANSÃO E TRANSNACIONALIZAÇÃO

Esse trabalho trata das estratégias de implantação e expansão da Igreja Universal do Reino de Deus (IURD) na África Subsaariana, tendo conta de crescimento acelerado do pentecostalismo no mundo e no contexto da transnacionalização religiosa. A IURD é uma Igreja neopentecostal brasileira que surgiu em 1977 e se expandiu em vários países do mundo. Ela está presente em 39 países da África subsaariana e se concentra nas grandes cidades. Vários fatores explicam o seu crescimento e expansão no continente africano, entre os quais o sincretismo, isto é, a capacidade de se adaptar à cultura africana. Outros fatores são: a visibilidade social (especialmente no uso da mídia e a assistência social), a política do segredo, a prática de exorcismo, o discurso da prosperidade, a relação de amizade e de parceria com governos africanos, a sua atitude anti-ecumênica e a adoção de uma organização episcopal. Aborda-se também nesse trabalho, o pentecostalismo e o neopentecostalismo na África, as Igrejas Independentes Africanas (IIA) e a presença do Cristianismo no continente africano desde os primórdios.

International student recruitment: South African rationales

In this paper, we focus on the rationales for the recruitment of international students to universities in South Africa. Through the use of in-depth interviews with international officers at a cross-section of South African universities, we argue that there are competing and complementary rationales for the recruitment of international students. Some South African universities follow international trends in terms of international student recruitment while others adopt a different approach. The analysis locates the rationales of international student recruitment as part of an internationalisation process within the context of globalisation. Dans cet article, nous nous focalisons sur les raisons derrière le recrutement des étudiants internationaux dans les universités de l'Afrique du Sud. Basé sur des interviews approfondies que nous avons menées avec les agents internationaux mandatés par les universités en Afrique du Sud, nous soutenons qu'il existe des raisons d'ordre compétitif et complémentaire qui expliquent le recrutement d'étudiants internationaux. Certaines universités sud africaines suivent la tendance de tels recrutement alors que d'autres adoptent une approche différente. Cette analyse identifie les raison du recrutement des étudiants internationaux dans le cadre du processus d'internationalisation dans le contexte de la globalisation.
