Vozes d'África Transatlântica: trajetórias estudantis de Cabo Verde e da Guiné-Bissau - programa de estudantes - convénio de graduação

A presente investigação tem como centralidade a mobilidade internacional de estudantes no caso, a dos africanos oriundos de Cabo Verde e da Guiné-Bissau, participantes do Programa Estudantes-Convênio de Graduação na Universidade Federal do Rio Grande do Norte - UFRN, inserida no fenômeno da internacionalização universitária, acentuada na globalização. O objetivo principal foi analisar o processo de inserção social e acadêmica desses estudantes, com ênfase para os dos cursos de Arquitetura e Urbanismo, Ciências da Computação, Engenharia da Computação e Medicina, nessa Instituição de Ensino Superior - IES. A metodologia foi norteada pela conjugação dos aportes teóricos e metodológicos qualiquantitativa, em que, na primeira, utilizou-se da entrevista semiestrutura dirigida para dezesseis sujeitos; sendo, a metade estudantes e a outra docentes, cuja análise optou-se pela Análise de Discurso (AD) da linha francesa, resultando as formações discursivas: motivações da mobilidade, registro nacional de estrangeiro, identidade étnica, relações étnicoraciais e o PEC-G: seu funcionamento nas práticas sociais na UFRN. Já a pesquisa quantitativa, foi constituída pela aplicação do questionário para o universo de 40 estudantes dos dois grupos e de todas as áreas de conhecimento, cuja interpretação dos dados, recorreu-se ao Programa SPSS. Já, para o recorte dos cursos específicos, foi utilizado, o do Google Doc, os quais, estão expressos em tabelas e gráficos. Os resultados revelaram que essa mobilidade estudantil africana está imersa por um misto de semelhanças e diferenças entre o Brasil e dos Países Africanos de Língua Oficial Poruguesa - PALOP; e mais dos contextos das hierarquias entre os países centrais, semiperiféricos e periféricos, provocadas pelas políticas de reajustes estruturais sobre os serviços educacionais, Sousa (Santos 2008; 2010), que se refletem nas trajetórias acadêmicas temporária no país de acolhimento. Aqui, também, enfrenta as fragilidades e os avanços das políticas públicas do Sistema de Ensino Superior, implementadas pelo governo brasileiro nas IES. Em termos quantitativos para os quatros cursos analisados, em diferentes e curtos períodos, quanto a distribuição de vagas (acesso), formas de desligamentos e conclusão apontaram especificidades. E, grosso modo, o curso de Medicina, apresentou os melhores índices de conclusão, seguidos, pelos de Arquitetura e da Engenharia da Computação. A maioria dos estudantes são do sexo masculino, mais da metade está representada pelos oriundos de Cabo Verde, o restante, pelos da Guiné-Bissau. Enquanto, no curso de Ciências da Computação, foi nula a conclusão de curso, e em função deste histórico de baixo desempenho dos estudantes-convênio PEC-G, teria havido o fechamento de vagas. Mas, verificando-se, que os índices de conclusão nesses cursos, apresentou uma média abaixo dos cursos de graduação da UFRN, nos quais, esses estudantes são minoria ao lado dos afrobrasileiros nas universidades do Brasil.

A política externa independente na questão da descolonização da África lusófona (1958 1964)

O presente trabalho destina-se a analisar as relações diplomáticas entre o Brasil e Portugal sobre a questão da independência da África lusófona. Até 1961, verifica-se a manutenção de uma relação privilegiada com a pátria lusitana, traduzida no incondicional apoio brasileiro prestado aos assuntos do interesse de Portugal que se colocavam nos foros internacionais, como por exemplo, a questão da descolonização africana, no âmbito da ONU.A Política Externa Independente, projeto formulado em 1961 pelo então Presidente Jânio Quadros e seu Chanceler, Afonso Arinos de Melo Franco, visava a renovação da ação externa do país. O anticolonialismo e a defesa da autodeterminação dos povos faziam parte das formulações da PEI, que, entretanto, acabou encontrando grandes dificuldades para manter a coerência no posicionamento brasileiro na ONU, diante do processo de descolonização dos territórios portugueses na África. Portugal manteve, durante todo o período analisado (1958-1964), uma forte estratégia de defesa da manutenção de seus territórios ultramarinos. O Brasil, por sua vez, encontrou, principalmente no nível interno, os maiores obstáculos para manter uma conduta assertiva na matéria colonial. A leitura das fontes primárias, bem como dos livros escritos pelos Chanceleres da PEI, constituiu importante metodologia para a comprovação de que houve contradições e abstenções por parte do Brasil, sobre a questão colonial portuguesa, entre 1961-1964, na ONU. E que a falta de unidade de posicionamento externada nas Assembléias refletia principalmente os embates internos, que provocaram as grandes oscilações demonstradas pela nossa Delegação nas mais importantes votações sobre a questão.

Designing self sustaining support for micro-enterprises in sub-Saharan Africa : a pilot

Small and micro-enterprises play a significant part in most economies. However, in developing countries these enterprises have often been planned and implemented from a poverty alleviation perspective, rather than as entrepreneurial activities and growing businesses (Mead & Liedholm 1998, Toye 1993). This paper explores a model for sustainable support to micro-enterprises in a developing country context. Sustainability is critical if micro-enterprises are to grow. The traditional philanthropic model for funding micro-enterprises leaves local communities dependent on the priorities of donors which may not always be consistent with those of the community. Long term sustainability requires a move to a model that broadens the base of both economic and intellectual resources, that builds capacity as well as providing ‘start-up’ funding through mechanism such as micro-credit (Elkington & Hartigan 2008). Designing for sustainable enterprise development includes responding to the community’s priorities, investigating individual problems and solutions, encouraging agency and active involvement in goal setting, with on-going consultation and co-development of solutions. Recognising the importance of experimentation we have moved beyond existing forms to prototype new ways of working which provide continuity of financial and intellectual support for local initiatives. The paper reviews existing micro finance and microcredit practices and suggests a new approach to establish and support enterprises with financial and knowledge resources for sustainable business practices. Principles underlying such a program and the initial steps are described.

Use of Bayesian geostatistical prediction to estimate local variations in Schistosoma haematobium infection in western Africa

Objective We aimed to predict sub-national spatial variation in numbers of people infected with Schistosoma haematobium, and associated uncertainties, in Burkina Faso, Mali and Niger, prior to implementation of national control programmes. Methods We used national field survey datasets covering a contiguous area 2,750 × 850 km, from 26,790 school-aged children (5–14 years) in 418 schools. Bayesian geostatistical models were used to predict prevalence of high and low intensity infections and associated 95% credible intervals (CrI). Numbers infected were determined by multiplying predicted prevalence by numbers of school-aged children in 1 km2 pixels covering the study area. Findings Numbers of school-aged children with low-intensity infections were: 433,268 in Burkina Faso, 872,328 in Mali and 580,286 in Niger. Numbers with high-intensity infections were: 416,009 in Burkina Faso, 511,845 in Mali and 254,150 in Niger. 95% CrIs (indicative of uncertainty) were wide; e.g. the mean number of boys aged 10–14 years infected in Mali was 140,200 (95% CrI 6200, 512,100). Conclusion National aggregate estimates for numbers infected mask important local variation, e.g. most S. haematobium infections in Niger occur in the Niger River valley. Prevalence of high-intensity infections was strongly clustered in foci in western and central Mali, north-eastern and northwestern Burkina Faso and the Niger River valley in Niger. Populations in these foci are likely to carry the bulk of the urinary schistosomiasis burden and should receive priority for schistosomiasis control. Uncertainties in predicted prevalence and numbers infected should be acknowledged and taken into consideration by control programme planners.

Measuring the success of ABC training in South Africa: A case study in the production of Western Liberal broadcast news values

In 1993 the Australian Broadcasting Corporation was contracted by the Australian Government to assist in the reshaping of the South African Broadcasting Corporation from a state-run broadcaster to a respected and trusted national broadcaster for all people in the newly democratic South Africa. Broadcast journalism training was identified by ABC consultant Bob Wurth as possibly the greatest need for SABC Radio. This thesis examines the ABC's role in South Africa and the effectiveness of its radio journalism training project considering the organisational, structural, cultural and political constraints of the SABC. This thesis will show through interviews and participant observation the difficulties in achieving the production of Western Liberal journalism values at the SABC within the time constraints set by the project funded by the Australian Government and the particular South African morays.

Positive design and construction of mechanisms for the sustainable development in microenterprises in Africa

Enterprise development and its contribution to societal and economic outcomes are well known. However, limited research into microenterprises and the practices of microfinance and microcredit in developing countries has been carried out. This chapter presents the findings of research based on six years of engagement with the microentrepreneurs of Beira in Mozambique and suggests a model for responsible and sustainable support for enterprise development in developing economies. Building on semistructured interviews, observation, and participatory action research, this research project articulates a new approach supportive of enterprise development, as a process of cocreation with local people and based on sustainability principles. These findings are part of a longitudinal study of the successes and failures of small enterprises and their impact on social and economic activity.

Molecular characterisation of six badnavirus species associated with leaf streak disease of banana in East Africa

Banana leaf streak disease, caused by several species of Banana streak virus (BSV), is widespread in East Africa. We surveyed for this disease in Uganda and Kenya, and used rolling-circle amplification (RCA) to detect the presence of BSV in banana. Six distinct badnavirus sequences, three from Uganda and three from Kenya, were amplified for which only partial sequences were previously available. The complete genomes were sequenced and characterised. The size and organisation of all six sequences was characteristic of other badnaviruses, including conserved functional domains present in the putative polyprotein encoded by open reading frame (ORF) 3. Based on nucleotide sequence analysis within the reverse transcriptase/ribonuclease H-coding region of open reading frame 3, we propose that these sequences be recognised as six new species and be designated as Banana streak UA virus, Banana streak UI virus, Banana streak UL virus, Banana streak UM virus, Banana streak CA virus and Banana streak IM virus. Using PCR and species-specific primers to test for the presence of integrated sequences, we demonstrated that sequences with high similarity to BSIMV only were present in several banana cultivars which had tested negative for episomal BSV sequences.

Broad Bean Stain Virus: Identification, Detectability with ELISA in Faba Bean Leaves and Seeds, Occurrence in West Asia and North Africa and Possible Wild Hosts

Abstract During a survey of faba bean viruses in West Asia and North Africa a virus was identified as broad bean stain virus (BBSV) based on host reactions, electron microscopy, physical properties and serology. An antiserum to a Syrian isolate was prepared. With this antiserum both the direct double antibody sandwich ELISA (DAS-ELISA) and dot-ELISA were very sensitive in detecting BBSV in leaf extracts, ground whole seeds and germi nated embryos. Sens it i vity was not reduced when the two-day procedure was replaced by a one-day procedure. us i ng ELISA the vi rus was detected in 73 out of 589 faba bean samples with virus-like symptoms collected from Egypt (4 out of 70 samples tested), Lebanon (6/44) , Morocco (017), Sudan (19/254), Syria (36/145) and Tunisia (8/69). This is the first report of BBSV infection of faba bean in Lebanon, Sudan, Syria and Tunisia. speci es i ndi genous to Syri a were Fourteen wild legume susceptible to BBSV infection, with only two producing obvious symptoms. The virus was found to be seed transmitted ~n Vicia palaestina.

Situation Review of Barley Yellow Dwarf Virus in West Asia and North Africa

Symptoms of barley yellow dwarf (BYD) have been observed on cereals in nearly all countries of West Asia and North Africa. Its incidence. however, has varied during the last 15 years. Observations from field surveys are summarized. Since symptoms of barley yellow dwarf virus (BYDV) are of low diagnostic value, especially in wheat (Triticum aestivum L.), more precise qualitative and quantitative detection was derived by vector transmission and serology. In 1985 and 1986. preliminary surveys by enzyme-linked immunosorbent assay (ELlS A) indicated that BYDV incidence in the regions surveyed in Syria, Morocco, and Tunisia was around 7. 22. and 24%. respectively. By vector transmission PAV-, RPV-, and RMV-like isolates ofBYDV were identified in Morocco and the PAV-like isolate in Syria. By serology PAV-like isolates were identified in Ethiopia, Lebanon. Morocco. Syria. and Tunisia. and MA V-like isolates were identified from Morocco and Tunisia. The PAV-like type was the most common in all countries surveyed. Screening for BYDV resistance by natural infection has been carried out in a number of countries of the region during the last few years. Screening for resistance by aphid inoculation was initiated in Syria in 1986 at the International Center for Agricultural Research in the Dry Areas (ICARDA). Such screening is expected to follow in other countries of the region soon.

Broad Bean Mottle Virus: Identification, Serology, Host Range, and Occurrence on Faba Bean (Vicia Faba) in West Asia and Norm Africa

One of the faba bean viruses found in West Asia and North Africa was identified as broad bean mottle virus (BBMV) by host reactions, particle morphology and size, serology, and granular, often vesiculated cytoplasmic inclusions. Detailed research on four isolates, one each from Morocco, Tunisia, Sudan and Syria, provided new information on the virus. The isolates, though indistinguishable in ELISA or gel-diffusion tests, differed slightly in host range and symptoms. Twenty-one species (12 legumes and 9 non-legumes) out of 27 tested were systemically infected, and 14 of these by all four isolates. Infection in several species was symptomless, but major legumes such as chickpea, lentil and especially pea, suffered severely from infection. All 23 genotypes of faba bean, 2 of chickpea, 4 of lentil, 11 out of 21 of Phaseolus bean, and 16 out of 17 of pea were systemically sensitive to the virus. Twelve plant species were found to be new potential hosts and cucumber a new local-lesion test plant of the virus. BBMV particles occurred in faba bean plants in very high concentrations and seed transmission in this species (1.37%) was confirmed. An isolate from Syria was purified and two antisera were produced, one of which was used in ELISA to detect BBMV in faba bean field samples. Two hundred and three out of the 789 samples with symptoms suggestive of virus infection collected in 1985, 1986 and 1987, were found infected with BBMV: 4 out of 70 (4/70) tested samples from Egypt, 0/44 from Lebanon, 1/15 from Morocco, 46/254 from Sudan, 72/269 from Syria and 80/137 from Tunisia. This is the first report on its occurrence in Egypt, Syria and Tunisia. The virus is a potential threat to crop improvement in the region.

The experience of xenophobia in South Africa

In May 2008, xenophobic violence erupted in South Africa. The targets were individuals who had migrated from the north in search of asylum. Emerging first in township communities around Johannesburg, the aggression spread to other provinces. Sixty-two people died, and 100,000 (20,000 in the Western Cape alone) were displaced. As the attacks escalated across the country, thousands of migrants searched for refuge in police stations and churches. Chilling stories spread about mobs armed with axes, metal bars, and clubs. The mobs stormed from shack to shack, assaulted migrants, locked them in their homes, and set the homes on fire. The public reaction was one of shock and horror. The Los Angeles Times declared, “Migrants Burned Alive in S. Africa.” The South African president at the time, Thabo Mbeki, called for an end to “shameful and criminal attacks.” Commentators were stunned by the signs of hatred of foreigners (xenophobia) that emerged in the young South African democracy. The tragedy of the violence in South Africa was magnified by the fact that many of the victims had fled from violence and persecution in their countries of origin. Amid genocidal violations of human rights that had recently occurred in some countries in sub- Saharan Africa, the new South Africa stood as a beacon of democracy and respect for human dignity. With this openness in mind, many immigrants to South Africa sought safety and refuge from the conflicts in their homelands. More than 43,500 refugees and 227,000 asylum seekers now live in South Africa. The majority of people accorded refugee status came from Burundi, Democratic Republic of Congo, and Somalia. South Africa also hosts thousands of other migrants who remain undocumented.

Humanitarianism or self-serving hypocrisy? : the provision of aid to South Africa under the Hawke-Keating and Howard governments

General perceptions of foreign aid commonly engender images of humanitarianism and altruism, whereby the humanitarian needs of the recipient of development assistance are of the utmost priority of the aid donor. However, the Australian governments led by Hawke, Keating and Howard often gave humanitarianism a low emphasis, frequently placing Australia’s own foreign policy and economic concerns at the forefront of aid allocation – often unashamedly. This self-interest met through aid meant that most was provided to Australia’s regional neighbourhood, neglecting some of the poorest, most struggling states, including South Africa. Other issues and events, including the Cold War, apartheid, terrorism and HIV/AIDS also affected Australia’s aid policy; mostly, they were used as excuses to limit aid to states like South Africa.

Review of de Bruijn, M., F. Nyamnjoh and I. Brinkman (eds.). 2009. Mobile phones : the new talking drums of everyday Africa

Since the late 1990s, there has been great enthusiasm expressed about the positive impact that can be obtained for poor and disadvantaged people from information and communication technologies (ICTs). This school of thought among researchers and practitioners is identified as ICTs for development (ICT4D). By contrast, a growing number of researchers eschew the technologically deterministic nature of the claims being made for development progress and seek to understand the role of technology in people’s lives, primarily through ethnographic studies. This book, which focuses on mobile telephony on the African continent, fits into the latter body of literature, with several authors explicitly stating they are examining social and cultural settings and are not taking a technologically deterministic view. The book captures the diverse ways various communities are using this communication technology. It adds to the burgeoning field of mobile phone studies, in which an increasing number of studies is emerging from developing countries.
