    Full Text Available Abstract Carolus Linnaeus was totally unacquainted with the Edible Dormouse Myoxus glis (L., a species not found in Sweden: while describing Mus Rattus in the 10th Edition of the "Systema Naturae" (1758, the Swedish naturalist confessed his ignorance concerning the "Glis" of the ancients and suggested that it might have been the marmot or the hamster. Thanks to written information received from his correspondent in Slovenia, Giovanni Antonio Scopoli, Linnaeus was able to include the new species Sciurus Glis in his 12th Edition of the "Systema Naturae" (1766, reporting almost verbatim a summary of Scopoli's description of the rodent. Scopoli's letter is still preserved in the Library of the Linnean Society of London. The Linnean type locality "Habitat in Europa australi" for the Edible Dormouse Myoxus glis glis must therefore be restricted to "Southern Carniola, Slovenia", contra "Germany" as stated, for instance, by Miller (1912, Toschi (1965, Corbet (1978 and Storch (1978. A new name is required for the continental European form, for which M. glis germanicus ssp. nov. is here proposed. Some information on the appreciation of Myoxus glis as a delicacy ("carnes avide eduntur" in Linnaeus' words conclude the paper. Riassunto Carlo Linneo ed il Ghiro - Dopo aver descritto Mus Rattus nella decima edizione del "Systema Naturae" (1758 il naturalista svedese Carlo Linneo confessava di non essere a conoscenza del "Glis" degli antichi autori e ne suggeriva l'identificazione con la Marmotta o con il Criceto comune; è infatti noto che Myoxus glis non è diffuso in Svezia. In base ad una lettera ricevuta dal suo corrispondente in Slovenia, Giovanni Antonio Scopoli, Linneo fu in grado di descrivere questa nuova specie come Sciurus Glis nella dodicesima edizione del "Systema

    Full Text Available The present study is trying to reveal the density of edible dormouse in beech forests of different ages and at different altitudes on the Semenic-Cheile Carasului National Park. The density was estimated based on two methods: with the already well known dormouse nestboxes and by census method. The results are analyzed and compared in order to provide the best solutions for dormouse monitoring in National Parks of Romania which have a chronic lack of personnel and resources.

  4. When morphometrics meet genetics: the case of the common dormouse, Muscardinus avellanarius

    2011-01-01

    The aim of the study is to apply geometric morphometrics to the study of evolutionary processes that might have driven intra-specific differentiation of the common dormouse Muscardinus avellanarius in Europe. The analysis of phenotypic features appears as a valuable complement to genetic analyses, providing a insight into evolutionary processes such as differentiation by vicariance or adaptation to different environments. Previous genetic studies based on mtDNA genes revealed a complex phylog...

  5. Genetic consequences of forest fragmentation for a highly specialized arboreal mammal--the edible dormouse.

    Directory of Open Access Journals (Sweden)

    Joanna Fietz

    Full Text Available Habitat loss and fragmentation represent the most serious extinction threats for many species and have been demonstrated to be especially detrimental for mammals. Particularly, highly specialized species with low dispersal abilities will encounter a high risk of extinction in fragmented landscapes. Here we studied the edible dormouse (Glis glis, a small arboreal mammal that is distributed throughout Central Europe, where forests are mostly fragmented at different spatial scales. The aim of this study was to investigate the effect of habitat fragmentation on genetic population structures using the example of edible dormouse populations inhabiting forest fragments in south western Germany. We genotyped 380 adult individuals captured between 2001 and 2009 in four different forest fragments and one large continuous forest using 14 species-specific microsatellites. We hypothesised, that populations in small forest patches have a lower genetic diversity and are more isolated compared to populations living in continuous forests. In accordance with our expectations we found that dormice inhabiting forest fragments were isolated from each other. Furthermore, their genetic population structure was more unstable over the study period than in the large continuous forest. Even though we could not detect lower genetic variability within individuals inhabiting forest fragments, strong genetic isolation and an overall high risk to mate with close relatives might be precursors to a reduced genetic variability and the onset of inbreeding depression. Results of this study highlight that connectivity among habitat fragments can already be strongly hampered before genetic erosion within small and isolated populations becomes evident.

  6. A review of the Dormouse (Muscardinus avellanarius in England and a Conservation Programme to safeguard its future

    1995-05-01

    Full Text Available Abstract The dormouse is native to Britain, but has apparently suffered decline in both distribution and numbers over the past 100 years. Basic ecological data have been lacking, hindering understanding of the decline and preventing implementation of scientifically based conservation measures. Recent studies are reviewed which reveal that this species is a specialist arboreal feeder, critically dependent for food upon a sequence of flowers and fruits during the summer. Woodland management (or lack of it and habitat fragmentation have resulted in habitats becoming sub-optimal, leading to piecemeal local extinctions. In addition, it is likely that the highly unpredictable maritime climate found in Britain results in very variable annual recruitment rates, increasing the vulnerability of small populations in fragmented habitats. With better understanding of the ecology of this species, a conservation strategy is being implemented. This aims to defend dormouse populations where they still occur and to attempt reintroductions to areas from which they have been lost. Riassunto Una revisione del Moscardino (Muscardinus avellanarius in Inghilterra e un programma di conservazione per salvaguardure il suo futuro - Il Moscardino è nativo della Gran Bretagna, ma ha subito una evidente riduzione nella distribuzione e nel numero di individui negli ultimi 100 anni. La mancanza di dati ecologici di base ha impedito la comprensione di tale declino e ostacolato la messa a punto di metodi scientifici di conservazione. Recenti studi hanno rivelato che questa specie è specialista arborea, dipendente per il cibo da una successione di fiori e frutti durante l'estate. La gestione dei boschi (o la sua mancanza e la frammentazione dell'habitat hanno portato ad ambienti subottimali ed a frammentarie estinzioni locali. Inoltre, è probabile che il clima marittimo altamente imprevedibile in Gran Bretagna porti a

  7. Laboratory Investigations of African Pouched Rats (Cricetomys gambianus as a Potential Reservoir Host Species for Monkeypox Virus.

    Directory of Open Access Journals (Sweden)

    Christina L Hutson

    Full Text Available Monkeypox is a zoonotic disease endemic to central and western Africa, where it is a major public health concern. Although Monkeypox virus (MPXV and monkeypox disease in humans have been well characterized, little is known about its natural history, or its maintenance in animal populations of sylvatic reservoir(s. In 2003, several species of rodents imported from Ghana were involved in a monkeypox outbreak in the United States with individuals of three African rodent genera (Cricetomys, Graphiurus, Funisciurus shown to be infected with MPXV. Here, we examine the course of MPXV infection in Cricetomys gambianus (pouched Gambian rats and this rodent species' competence as a host for the virus. We obtained ten Gambian rats from an introduced colony in Grassy Key, Florida and infected eight of these via scarification with a challenge dose of 4X104 plaque forming units (pfu from either of the two primary clades of MPXV: Congo Basin (C-MPXV: n = 4 or West African (W-MPXV: n = 4; an additional 2 animals served as PBS controls. Viral shedding and the effect of infection on activity and physiological aspects of the animals were measured. MPXV challenged animals had significantly higher core body temperatures, reduced activity and increased weight loss than PBS controls. Viable virus was found in samples taken from animals in both experimental groups (C-MPXV and W-MPXV between 3 and 27 days post infection (p.i. (up to 1X108 pfu/ml, with viral DNA found until day 56 p.i. The results from this work show that Cricetomys gambianus (and by inference, probably the closely related species, Cricetomys emini can be infected with MPXV and shed viable virus particles; thus suggesting that these animals may be involved in the maintenance of MPXV in wildlife mammalian populations. More research is needed to elucidate the epidemiology of MPXV and the role of Gambian rats and other species.

    1990-07-01

    Full Text Available Abstract A new and simplified method was used to investigate on the feeding habits of a Dormouse population of the Asiago Plateau, Venetian Prealps; it is based on the volume evaluation of plant and animal components of the stomach contents by stain proceedings and by the identification of the large-sized remains. The population studied has more carnivorous habits than others cited in the literature, and presents an increasing percentage of animal food in stomach contents during: (1 the summer decrease in body weight (linked to an higher energy consumption, (2 sexual activity and (3 the period preceding hibernation. The diet variety is lower and the ground level predation higher than those reported for other populations. This anomalous trophic behaviour is probably a consequence of changed conditions of the biocenosis, originally based on Beech stands and now on artificial pure stands of Norway Spruce, which is not frequently utilized as food. The adaptation to this particular diet is prompt and general, and it must be related to social learning. Riassunto Per studiare il comportamento trofico di una popolazione di Ghiro (Myoxus glis L. dell'Altopiano di Asiago, Prealpi Venete, è stato utilizzato un metodo nuovo e semplificato rispetto ai precedenti, basato sulla valutazione dei volumi della componente animale e vegetale mediante analisi di tipo colorimetrico, e sulla classificazione dei residui di maggiori dimensioni dei contenuti stomacali. La popolazione in esame è risultata di abitudini più carnivore (con differenze tra i maschi e le femmine rispetto a popolazioni studiate da altri autori, presentando una maggiore percentuale di cibo animale nel contenuto stomacale durante la diminuzione estiva in peso corporeo (associata a sua volta ad un elevato consumo energetico, durante l'attività sessuale e prima del letargo.

  18. Female genital mutilation in African and African American women's literature

    Directory of Open Access Journals (Sweden)

    Darja Marinšek

    2007-12-01

    Full Text Available The article builds on the existing dispute between African and African American women writers on the competence of writing about female genital mutilation (FGM, and tries to determine the existence and nature of the differences between the writings of these two groups. The author uses comparative analysis of two popular African and African American novels, comparing their ways of describing FGM, its causes and consequences, the level ob objectivity and the style of the narrations.This is followed by a discussion on the reasons for such differences, incorporating a larger circle of both African and African American women authors, at the same time analysing the deviance within the two groups. While the differences between African American writers are not that great, as they mostly fail to present the issue from different points of view, which is often the result of their lack of direct knowledge of the topic, African authors' writing is in itself discovered to be ambivalent and not at all invariable. The reasons for such ambivalence are then discussed in greater context, focusing on the effect of the authors' personal contact with circumcision as well as their knowledge and acceptance of Western values. The author concludes by establishing the African ambivalent attitude towards FGM, which includes different aspects of the issue, as the most significant difference between their and African American writers' description of this practice.

  19. Leadership in the African context

    Directory of Open Access Journals (Sweden)

    M. Masango

    2002-08-01

    Full Text Available The Western world has always viewed the African continent as plagued by corruption; dictatorship; military coups; rebellious leaders; greediness; misuse of power; and incompetent, politically unstable leaders - in effect, suspicious leaders who undermine their own democracies. This paper analyzes African leadership and its impact by concentrating on three historical eras, namely; the African Religious era; the Christian era, and the era of Globalization. These affected African leadership. In addition, many brilliant minds left the continent in search of greener pastures. A review of these three eras will help us understand how leadership shifted from African values into Western concepts. The role of missionaries lead African people to live with both an African and a Western concept of life. In spite of the above problems, our past leaders did their best in addressing the difficulties they faced during the three eras. African concepts of leadership were often regarded as barbaric and uncultured. Structures were evaluated by Western standards. Due to globalisation, African leaders, through programmes like NEPAD, are going back to basics, drawing on African concepts of unity among its leadership. Effectiveness or life-giving leadership is emerging and empowering villagers/communities in the continent. This type of leadership is innovative and has brought new hope for the continent.

    2010-01-01

    Although dissimilarities in cranial and post-cranial morphology among African pygmies groups have been recognized, comparative studies on skull morphology usually pull all pygmies together assuming that morphological characters are similar among them and different with respect to other populations. The main aim of this study is to compare cranial morphology between African pygmies and non-pygmies populations from Equatorial Africa derived from both the Eastern and the Western regions in order to test if the greatest morphological difference is obtained in the comparison between pygmies and non-pygmies. Thirty three-dimensional (3D) landmarks registered with Microscribe in four cranial samples (Western and Eastern pygmies and non-pygmies) were obtained. Multivariate analysis (generalized Procrustes analysis, Mahalanobis distances, multivariate regression) and complementary dimensions of size were evaluated with ANOVA and post hoc LSD. Results suggest that important cranial shape differentiation does occur between pygmies and non-pygmies but also between Eastern and Western populations and that size changes and allometries do not affect similarly Eastern and Western pygmies. Therefore, our findings raise serious doubt about the fact to consider African pygmies as a homogenous group in studies on skull morphology. Differences in cranial morphology among pygmies would suggest differentiation after divergence. Although not directly related to skull differentiation, the diversity among pygmies would probably suggest that the process responsible for reduced stature occurred after the split of the ancestors of modern Eastern and Western pygmies.

    In July 2006, the African Non-Petroleum Producers Association was formed in Senegal, Africa to develop alternative energy sources. It involved 13 of Africa's poorest nations, who joined forces to become global suppliers of biofuels, and some have set mandatory mixing of ethanol into gasoline. Although several biofuel production projects have been launched in western Africa, many of the new projects and plantations have not yet reached maturity due to the time lag between plantation and full-scale production, which is about 6 years. Major projects that could be producing significant quantities of biofuels in the next few years are not yet reflected in production statistics. Although ethanol is not yet being produced in large quantities in Africa, short-term opportunities exist. Countries in the South African Development Community are using molasses from the sugar can industry to produce ethanol. Biodiesel is also not currently produced on a significant scale in western Africa, but several other countries are gaining experience with cotton and palm oil resources, and Jatropha. Biomass residue also represents a large potential for all African countries involved in timber production. Unlike biodiesel production, land use conflicts are not an issue with biomass residue production.

    Since the 1960s, African states have embraced regional integration as a vital mechanism for political cooperation and for pooling resources to overcome problems of small and fragmented economies. In building meaningful institutions for regionalism, however, Africans have faced the challenges of reconciling the diversities of culture, geography, and politics. As a result, African regional institutions are characterized by multiple and competing mandates and weak institutionalization. This stud...

    Among the world's continents, Africa has the highest incidence of food insecurity and poverty and the highest rates of population growth. Yet Africa also has the most arable land, the lowest crop yields, and by far the most plentiful land resources relative to energy demand. It is thus of interest to examine the potential of expanded modern bioenergy production in Africa. Here we consider bioenergy as an enabler for development, and provide an overview of modern bioenergy technologies with a comment on application in an Africa context. Experience with bioenergy in Africa offers evidence of social benefits and also some important lessons. In Brazil, social development, agricultural development and food security, and bioenergy development have been synergistic rather than antagonistic. Realizing similar success in African countries will require clear vision, good governance, and adaptation of technologies, knowledge, and business models to myriad local circumstances. Strategies for integrated production of food crops, livestock, and bioenergy are potentially attractive and offer an alternative to an agricultural model featuring specialized land use. If done thoughtfully, there is considerable evidence that food security and economic development in Africa can be addressed more effectively with modern bioenergy than without it. Modern bioenergy can be an agent of African transformation, with potential social benefits accruing to multiple sectors and extending well beyond energy supply per se. Potential negative impacts also cut across sectors. Thus, institutionally inclusive multi-sector legislative structures will be more effective at maximizing the social benefits of bioenergy compared to institutionally exclusive, single-sector structures.

    Places where the earth's crust has formed deep fissures and the plates have begun to move apart develop rift structures in which elongate blocks have subsided relative to the blocks on either side. The East African Rift is a world-famous example of such rifting. It is characterized by 1) topographic deep valleys in the rift zone, 2) sheer escarpments along the faulted walls of the rift zone, 3) a chain of lakes within the rift, most of the lakes highly saline due to evaporation in the hot temperatures characteristic of climates near the equator, 4) voluminous amounts of volcanic rocks that have flowed from faults along the sides of the rift, and 5) volcanic cones where magma flow was most intense. This example in Kenya displays most of these features near Lake Begoria. The image was acquired December 18, 2002, covers an area of 40.5 x 32 km, and is located at 0.1 degrees north latitude, 36.1 degrees east longitude.

  6. Disarmament: the African perspective

    International Nuclear Information System (INIS)

    Disarmament is now generally accepted as the process of reduction in the size of, and expenditures on, armed forces, the destruction or dismantling of weapons, whether deployed or stockpiled, the progressive elimination of the capacity to produce new weapons and the release and integration into civilian life of military personnel. To realize this objective, the nations of the world have been advocating such measures as the establishment of nuclear weapon-free zones, non-proliferation, limitation of the arms trade, reduction of military budgets, and confidence-building measures. To ensure general and complete elimination of arms, there has been widespread recognition of the need to link the disarmament process with other political as well as socio-economic problems of the world such as the need for security, good relations between states and development of a system of peaceful settlement of disputes. Other measures that have been considered to be relevant in boosting the disarmament process include the role of the general public in putting pressure on their respective governments with a view to accelerating and realizing disarmament objectives. Africans have presented to the world a strong case for global disarmament

  7. An African ethic for nursing?

    Science.gov (United States)

    Haegert, S

    2000-11-01

    This article derives from a doctoral thesis in which a particular discourse was used as a 'paradigm case'. From this discourse an ethic set within a South African culture arose. Using many cultural 'voices' to aid the understanding of this narrative, the ethic shows that one can build on both a 'justice' and a 'care' ethic. With further development based on African culture one can take the ethic of care deeper and reveal 'layers of understanding'. Care, together with compassion, forms the foundation of morality. Nursing ethics has followed particular western moral philosophers. Often nursing ethics has been taught along the lines of Kohlberg's theory of morality, with its emphasis on rules, rights, duties and general obligations. These principles were universalistic, masculine and noncontextual. However, there is a new ethical movement among Thomist philosophers along the lines to be expounded in this article. Nurses such as Benner, Bevis, Dunlop, Fry and Gadow--to name but a few--have welcomed the concept of an 'ethic of care'. Gilligan's work gave a feminist view and situated ethics in the everyday aspects of responsiveness, responsibility, context and concern. Shutte's search for a 'philosophy for Africa' has resulted in finding similarities in Setiloane and in Senghor with those of Thomist philosophers. Using this African philosophy and a research participant's narrative, an African ethic evolves out of the African proverb: 'A person is a person through other persons', or its alternative rendering: 'I am because we are: we are because I am.' This hermeneutic narrative reveals 'the way affect imbues activity with ethical meaning' within the context of a black nursing sister in a rural South African hospital. It expands upon the above proverb and incorporates the South African constitutional idea of 'Ubuntu' (compassion and justice or humanness).

    Africa's smallholder agricultural systems face unique challenges in planning for reducing poverty, concurrent with adaptation and mitigation to climate change. At continental level, policy seeks to promote a uniquely African Green Revolution to increase crop yields and food production, and improve local livelihoods. However, the consequences on the environment and climate are not clear; these pro-economic development measures should be linked to climate change adaptation and mitigation measures, and research is required to help achieve these policy proposals by identifying options, and testing impacts. In particular, increased nitrogen (N) inputs are essential for increasing food production in Africa, but are accompanied by inevitable increases in losses to the environment. These losses appear to be low at input levels promoted in agricultural development programs, while the increased N inputs both increase current food production and appear to reduce the vulnerability of food production to changes in climate. We present field and remote sensing evidence from Malawi that subsidizing improved seed and fertilizers increases resilience to drought without adding excess N to the environment. In Kenya, field research identified thresholds in N2O losses, where emissions are very low at fertilization rates of less than 200 kg ha-1. Village-scale models have identified potential inefficiencies in the food production process where the largest losses of reactive N occur, and which could be targeted to reduce the amount of N released to the environment. We further review some on-going research activities and progress in Africa that compare different methods of managing resources that target resilience in food production and adaptation to climate change, using nutrient N as an indicator, while evaluating the effects of these resource management practices on ecosystems and the environment.

  9. African horse sickness.

    Mellor, Philip Scott; Hamblin, Christopher

    2004-01-01

    African horse sickness virus (AHSV) causes a non-contagious, infectious insect-borne disease of equids and is endemic in many areas of sub-Saharan Africa and possibly Yemen in the Arabian Peninsula. However, periodically the virus makes excursions beyond its endemic areas and has at times extended as far as India and Pakistan in the east and Spain and Portugal in the west. The vectors are certain species of Culicoides biting midge the most important of which is the Afro-Asiatic species C. imicola. This paper describes the effects that AHSV has on its equid hosts, aspects of its epidemiology, and present and future prospects for control. The distribution of AHSV seems to be governed by a number of factors including the efficiency of control measures, the presence or absence of a long term vertebrate reservoir and, most importantly, the prevalence and seasonal incidence of the major vector which is controlled by climate. However, with the advent of climate-change the major vector, C. imicola, has now significantly extended its range northwards to include much of Portugal, Spain, Italy and Greece and has even been recorded from southern Switzerland. Furthermore, in many of these new locations the insect is present and active throughout the entire year. With the related bluetongue virus, which utilises the same vector species of Culicoides this has, since 1998, precipitated the worst outbreaks of bluetongue disease ever recorded with the virus extending further north in Europe than ever before and apparently becoming endemic in that continent. The prospects for similar changes in the epidemiology and distribution of AHSV are discussed.

    Aldhoun, Jitka A; Horne, Elizabeth C

    2015-01-01

    During the years 2009-2012, faeces of African penguins (Spheniscus demersus L.) from South African rehabilitation centres were examined for helminths. In total, 46 out 555 samples (8.29 %), mostly belonging to adult birds, were found to contain oval schistosome eggs with a spine on one pole. Their dimensions were 153.21 ± 9.07 × 87.14 ± 8.67 μm. Selected DNA fragments (18S, 28S and ITS rDNA) were sequenced and compared to other schistosome isolates deposited in GenBank. The shape of the eggs suggests that they belong to the genus Gigantobilharzia; however, due to the insufficient stage of knowledge of the genus and limited number of species available for comparison, we were not able to assign the isolate unambiguously to this genus based on either the egg morphology or the results of molecular analysis.

  7. Palaearctic-African Bird Migration

    DEFF Research Database (Denmark)

    Iwajomo, Soladoye Babatola

    Bird migration has attracted a lot of interests over past centuries and the methods used for studying this phenomenon has greatly improved in terms of availability, dimension, scale and precision. In spite of the advancements, relatively more is known about the spring migration of trans......-Saharan migrants than autumn migration. Information about the behavior and interactions of migrants during the nonbreeding season in sub-Saharan Africa is also scarce for many species. Furthermore, very little is known about intra-African migration. This thesis summarizes my research on the autumn migration...... of birds from Europe to Africa and opens up the possibility of studying intra-African migration. I have used long-term, standardized autumn ringing data from southeast Sweden to investigate patterns in biometrics, phenology and population trends as inferred from annual trapping totals. In addition, I...

    Almost a decade after their initiation, financial reforms appear to have had little effect on the economies of Sub-Sahara Africa. Whether the blame is to fall on their initial design itself, or on the partial nature of their implementation, liberalization policies have not mobilized savings, deepened intermediation or raised investment. Yet, Africa needs properly functioning financial markets for a more efficient allocation of resources for growth and risk diversification. How can African go...

    2012-11-01

    Oceanic islands have reduced resources and natural enemies and potentially affect life history traits of arriving organisms. Among the most spectacular invasions in the Western hemisphere is that of the Africanized honeybee. We hypothesized that in the oceanic island Puerto Rico, Africanized bees will exhibit differences from the mainland population such as for defensiveness and other linked traits. We evaluated the extent of Africanization through three typical Africanized traits: wing size, defensive behavior, and resistance to Varroa destructor mites. All sampled colonies were Africanized by maternal descent, with over 65% presence of European alleles at the S-3 nuclear locus. In two assays evaluating defense, Puerto Rican bees showed low defensiveness similar to European bees. In morphology and resistance to mites, Africanized bees from Puerto Rico are similar to other Africanized bees. In behavioral assays on mechanisms of resistance to Varroa, we directly observed that Puerto Rican Africanized bees groomed-off and bit the mites as been observed in other studies. In no other location, Africanized bees have reduced defensiveness while retaining typical traits such as wing size and mite resistance. This mosaic of traits that has resulted during the invasion of an oceanic island has implications for behavior, evolution, and agriculture.

    Full Text Available This article explores the extent to which the role of the African biblical interpreter is acknowledged in the process of Bible translation, as the Bible and Bible translation form an important part of the establishment of the African church on the continent of Africa. It points out that even though foreign discovery of African agency in Bible translation is evident, indigenous discovery of the same is largely absent. Part of the relevance of this article is for the African church to own and be actively involved in the translation of the Bible into the remaining African languages that are in need of a translation of the Bible.

  4. Prostate cancer in men of African origin.

    Science.gov (United States)

    McGinley, Kathleen F; Tay, Kae Jack; Moul, Judd W

    2016-02-01

    Men of African origin are disproportionately affected by prostate cancer: prostate cancer incidence is highest among men of African origin in the USA, prostate cancer mortality is highest among men of African origin in the Caribbean, and tumour stage and grade at diagnosis are highest among men in sub-Saharan Africa. Socioeconomic, educational, cultural, and genetic factors, as well as variations in care delivery and treatment selection, contribute to this cancer disparity. Emerging data on single-nucleotide-polymorphism patterns, epigenetic changes, and variations in fusion-gene products among men of African origin add to the understanding of genetic differences underlying this disease. On the diagnosis of prostate cancer, when all treatment options are available, men of African origin are more likely to choose radiation therapy or to receive no definitive treatment than white men. Among men of African origin undergoing surgery, increased rates of biochemical recurrence have been identified. Understanding differences in the cancer-survivorship experience and quality-of-life outcomes among men of African origin are critical to appropriately counsel patients and improve cultural sensitivity. Efforts to curtail prostate cancer screening will likely affect men of African origin disproportionately and widen the racial disparity of disease.

    2008-01-01

    Full Text Available Abstract Background The migration of doctors and nurses from Africa to developed countries has raised fears of an African medical brain drain. But empirical research on the causes and effects of the phenomenon has been hampered by a lack of systematic data on the extent of African health workers' international movements. Methods We use destination-country census data to estimate the number of African-born doctors and professional nurses working abroad in a developed country circa 2000, and compare this to the stocks of these workers in each country of origin. Results Approximately 65,000 African-born physicians and 70,000 African-born professional nurses were working overseas in a developed country in the year 2000. This represents about one fifth of African-born physicians in the world, and about one tenth of African-born professional nurses. The fraction of health professionals abroad varies enormously across African countries, from 1% to over 70% according to the occupation and country. Conclusion These numbers are the first standardized, systematic, occupation-specific measure of skilled professionals working in developed countries and born in a large number of developing countries.

    African trypanosomes, which divide their life cycle between mammals and tsetse flies, are confronted with environments that differ widely in temperature, nutrient availability and host responses to infection. In particular, since trypanosomes cannot predict when they will be transmitted between hosts, it is vital for them to be able to sense and adapt to their milieu. Thanks to technical advances, significant progress has been made in understanding how the parasites perceive external stimuli and react to them. There is also a growing awareness that trypanosomes use a variety of mechanisms to exchange information with each other, thereby enhancing their chances of survival. PMID:27131101

    The advent of international wideband communication by optical fibre has produced a revolution in communications and the use of the internet. Many African countries are now connected to undersea fibre linking them to other African countries and to other continents. Previously international communication was by microwave links through geostationary satellites. These are becoming redundant in some countries as optical fibre takes over, as this provides 1000 times the bandwidth of the satellite links. In the 1970's and 1980's some two dozen large (30 m diameter class) antennas were built in various African countries to provide the satellite links. Twenty six are currently known in 19 countries. As these antennas become redundant, the possibility exists to convert them for radio astronomy at a cost of roughly one tenth that of a new antenna of similar size. HartRAO, SKA Africa and the South African Department of Science and Technology (DST) have started exploring this possibility with some of the African countries...

    1998-10-17

    In a television broadcast, Deputy President Mbeki of South Africa announced a campaign against HIV/AIDS that would involve coordination between various government departments and nongovernmental organizations. Mbeki, who is associated with Virodene (a drug treatment for AIDS that is considered a scam), replaced President Mandela at the last minute in the broadcast. Two days after the broadcast, the government refused to support treatment of pregnant women infected with HIV with zidovudine to prevent transmission of the virus to the baby. The treatment is considered cost-effective by AIDS workers and public health officials. According to Mark Heywood of the AIDS law project at Witwatersrand University, 16% of pregnant women attending antenatal clinics were HIV-positive in 1997; this means that about 3 million South Africans (8% of the population) were living with HIV. Heywood said that the government believes there are 1500 new cases daily. By the end of 1998, 3.5 million South Africans will be living with HIV. Although the government is asking other sectors to join in the campaign, what the government is doing is unclear. Mother-to-child transmission of HIV is second only to transmission of the virus through heterosexual sex in South Africa. PMID:9841037

    Full Text Available Major depression is a very common disabling disorder. Although the relationship between race and depression is complex, depression affects all races, all ethnic and geographic locations as well as all age groups. The prevalence of depression in African Americans is controversial, due to the paucity of research. The deficit in the knowledge and skills in treating depression in African Americans have not been adequately addressed so far. Inadequate and insufficient data on African Americans contributes to the problems of under diagnoses, misdiagnosis and under treatment of depression. This article will highlight the existing problem of depression in Afro American with a focus on diagnostic and treatment issues.

  1. African diatom palaeoecology and biostratigraphy

    Science.gov (United States)

    Gasse, F.; Fourtanier, E.

    This paper illustrates the different types of information which can be deduced from African diatoms studies. The first section is devoted to the reconstruction of palaeoenvironments. The accuracy of ecological data (estimates of ecological variables e.g. types of habitats, water chemistry…) depends on the times scale and on the spatial scale considered: short-term environments in a given waterbody, environmental evolution during individual humid episodes considered locally or regionally, long-term changes in diatom flora induced by major climatic tendencies at a regional or continental scale. One then summarizes our present state of knowledge in diatom biostratigraphy in Africa. Several centric taxa, belonging to the genera Aulacoseira, Mesodictyon, Cyclotella, Stephanodiscus and Cyclostephanos appear to have limited stratigraphical ranges and to be good chronological markers.

    Full Text Available The Federation of European Biochemical Societies (FEBS was the first regional organisation of biochemists, holding its first congress in London in 1964. There followed the creation of the Pan American Association of Biochemical Societies (PAABS and then the Federation of Asian and Oceanian Biochemists (FAOB. An obvious development was the formation of a similar organisation to take care of Africa, but this proved impossible so long as apartheid survived in South Africa. With the removal of the latter, the way was clear for the foundation of the Federation of African Societies of Biochemistry and Molecular Biology (FASBMB. The first congress of the new federation was held in Nairobi in September 1996 under the Presidency of Prof. Dominic Makawiti of Nairobi University. Among the 300 participants were representatives from 19 countries in Africa. The second congress was held at Potchefstroom in South Africa in 1998 and the third was just held in Cairo.

  4. Enhancing the African bioethics initiative

    Directory of Open Access Journals (Sweden)

    Ogundiran Temidayo O

    2004-10-01

    Full Text Available Abstract Background Medical ethics has existed since the time of Hippocrates. However, formal training in bioethics did not become established until a few decades ago. Bioethics has gained a strong foothold in health sciences in the developed world, especially in Europe and North America. The situation is quite different in many developing countries. In most African countries, bioethics – as established and practiced today in the west- is either non-existent or is rudimentary. Discussion Though bioethics has come of age in the developed and some developing countries, it is still largely "foreign" to most African countries. In some parts of Africa, some bioethics conferences have been held in the past decade to create research ethics awareness and ensure conformity to international guidelines for research with human participants. This idea has arisen in recognition of the genuine need to develop capacity for reviewing the ethics of research in Africa. It is also a condition required by external sponsors of collaborative research in Africa. The awareness and interest that these conferences have aroused need to be further strengthened and extended beyond research ethics to clinical practice. By and large, bioethics education in schools that train doctors and other health care providers is the hook that anchors both research ethics and clinical ethics. Summary This communication reviews the current situation of bioethics in Africa as it applies to research ethics workshops and proposes that in spite of the present efforts to integrate ethics into biomedical research in Africa, much still needs to be done to accomplish this. A more comprehensive approach to bioethics with an all-inclusive benefit is to incorporate formal ethics education into health training institutions in Africa.

    2011-03-01

    Cardiomyopathy is a common finding in captive African hedgehogs (Atelerix albiventris) at postmortem exam. To date, treatment attempts have been mostly empirical and unrewarding. The objective of this study was to determine reference cardiac values for captive African hedgehogs based on echocardiogram, electrocardiogram (ECG), and radiographs. Adult African hedgehogs with no clinical signs of cardiac disease (n = 13) were selected. Each animal was anesthetized with isoflurane via facemask and an echocardiogram, ECG, and radiographs were performed. Standard measurements were taken and the descriptive statistics performed. Values were comparable to limited data available in other hedgehog species and other similar-sized exotic species. Two animals were removed from consideration of reference values due to valvular defects that were considered significant. These data are the first establishing cardiac parameters in normal African hedgehogs using radiographic cardiac measurement, echocardiogram, and ECG. Evaluating animals with possible cardiomyopathy may allow for earlier diagnosis and more successful treatment. PMID:22946370

    Full Text Available It has been said that 'Necessity is the mother of invention' and there can be few countries, if any, where this is more true than in South Africa.In the late 1930's, prior to World War II, the South African Artillery was severely restricted due to its lack of mobility. The inventiveness shown in tackling this probelm is surely not a thing of the past and the possiblity of adapting South African artillery to current South african needs in warfare should not be overlooked. The South African Defence Force is not able to purchase armament in a free and open market place and the costs of developing new artillery are prohibitive in a country of South Africa's size. it will be argued that it is necessary and possible, in the short term, to take what is currently available and adapt this to South Africa's needs.

  12. The innovative African kilowatt-hour

    International Nuclear Information System (INIS)

    There is a worldwide resurgence of interest in pricing electricity. Whether motivated by deregulation and the treat of competition (as in England and New Zealand) or by restructuring of regulatory goals to encourage competition or conservation (as in the United States), electricity suppliers and distributors are seeing pricing as a means of safeguarding, maintaining, increasing sales. South Africa is no exception in this regard. Past and proposed new developments in electricity pricing in the South African electricity supply industry are discussed, in response to pressures across several fronts: pressures from customers to reduce electricity prices to facilitate growth and survival in the South African economy; the national electrification program; the appointment of the National Electricity Regulator; moves by Southern African electricity utilities to establish a Southern African grid. The current status of electricity pricing, metering, demand profile research and demand management in South Africa are overviewed. (author)

    1998-04-01

    A 3-mo-old, male African hedgehog (Atelerix albiventris) was anorectic and lethargic for a period of 3 days prior to death. Necropys revealed lungs that were diffusely firm, dark red, and dorsally adhered by fibrinous tags to the pericardial sac. Histopathology revealed necrosuppurative bronchopneumonia with pulmonary abscesses and suppurative pericarditis and myocarditis. A Corynebacterium sp. was isolated from the lungs. We believe this is the first reported case of corynebacterial pneumonia in an African hedgehog. PMID:9577794

    2015-11-01

    The honeybee, Apis mellifera, is the world's most important pollinator and is ubiquitous in most agricultural ecosystems. Four major evolutionary lineages and at least 24 subspecies are recognized. Commercial populations are mainly derived from subspecies originating in Europe (75-95%). The Africanized honeybee is a New World hybrid of A. m. scutellata from Africa and European subspecies, with the African component making up 50-90% of the genome. Africanized honeybees are considered undesirable for bee-keeping in most countries, due to their extreme defensiveness and poor honey production. The international trade in honeybees is restricted, due in part to bans on the importation of queens (and semen) from countries where Africanized honeybees are extant. Some desirable strains from the United States of America that have been bred for traits such as resistance to the mite Varroa destructor are unfortunately excluded from export to countries such as Australia due to the presence of Africanized honeybees in the USA. This study shows that a panel of 95 single nucleotide polymorphisms, chosen to differentiate between the African, Eastern European and Western European lineages, can detect Africanized honeybees with a high degree of confidence via ancestry assignment. Our panel therefore offers a valuable tool to mitigate the risks of spreading Africanized honeybees across the globe and may enable the resumption of queen and bee semen imports from the Americas.

  12. Henipavirus RNA in African bats.

    Directory of Open Access Journals (Sweden)

    Jan Felix Drexler

    Full Text Available BACKGROUND: Henipaviruses (Hendra and Nipah virus are highly pathogenic members of the family Paramyxoviridae. Fruit-eating bats of the Pteropus genus have been suggested as their natural reservoir. Human Henipavirus infections have been reported in a region extending from Australia via Malaysia into Bangladesh, compatible with the geographic range of Pteropus. These bats do not occur in continental Africa, but a whole range of other fruit bats is encountered. One of the most abundant is Eidolon helvum, the African Straw-coloured fruit bat. METHODOLOGY/PRINCIPAL FINDINGS: Feces from E. helvum roosting in an urban setting in Kumasi/Ghana were tested for Henipavirus RNA. Sequences of three novel viruses in phylogenetic relationship to known Henipaviruses were detected. Virus RNA concentrations in feces were low. CONCLUSIONS/SIGNIFICANCE: The finding of novel putative Henipaviruses outside Australia and Asia contributes a significant extension of the region of potential endemicity of one of the most pathogenic virus genera known in humans.

  3. Population Genomics of sub-saharan Drosophila melanogaster: African diversity and non-African admixture.

    Directory of Open Access Journals (Sweden)

    John E Pool

    Full Text Available Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved. We report the genome sequencing of 139 wild-derived strains of D. melanogaster, representing 22 population samples from the sub-Saharan ancestral range of this species, along with one European population. Most genomes were sequenced above 25X depth from haploid embryos. Results indicated a pervasive influence of non-African admixture in many African populations, motivating the development and application of a novel admixture detection method. Admixture proportions varied among populations, with greater admixture in urban locations. Admixture levels also varied across the genome, with localized peaks and valleys suggestive of a non-neutral introgression process. Genomes from the same location differed starkly in ancestry, suggesting that isolation mechanisms may exist within African populations. After removing putatively admixed genomic segments, the greatest genetic diversity was observed in southern Africa (e.g. Zambia, while diversity in other populations was largely consistent with a geographic expansion from this potentially ancestral region. The European population showed different levels of diversity reduction on each chromosome arm, and some African populations displayed chromosome arm-specific diversity reductions. Inversions in the European sample were associated with strong elevations in diversity across chromosome arms. Genomic scans were conducted to identify loci that may represent targets of positive selection within an African population, between African populations, and between European and African populations. A disproportionate number of candidate selective sweep regions were located near genes with varied roles in gene regulation. Outliers for Europe-Africa F(ST were found to be enriched in genomic regions of locally

    Full Text Available Emerging from the Second World War armed with the then completely adequate 25 pounder and BL 5.5" guns, the South African Field Artillery continued to use the same guns operationally over thirty years later.When the armed forces of South Africa were thrown into a conventional conflict during the Angolan Civil War in 1975, the gunners found their equipment to be woefully inadequate. Soviet made artillery systems in the hands of the Russian-backed forces possessed ranges far in excess of the Second World War vintage South African systems and brought home in a very real way the need for drastic modernisation of the artillery branch of the South African Army.

    From December 1995 to July 1999, eight mammary gland tumors were diagnosed in eight adult captive female African hedgehogs (Atelerix albiventris). The tumors presented as single or multiple subcutaneous masses along the cranial or caudal abdomen that varied in size for each hedgehog. Histologically, seven of eight (88%) mammary gland tumors were malignant. Tumors were classified as solid (4 cases), tubular (2 cases), and papillary (2 cases). Seven tumors had infiltrated into the surrounding stroma and three tumors had histologic evidence of neoplastic vascular invasion. Three hedgehogs had concurrent neoplasms. These are believed to be the first reported cases of mammary gland tumors in African hedgehogs. PMID:10813628

It also emphasizes the burden of cryptosporidiosis, which is underestimated due to the presence of many silent asymptomatic carriers.Cryptosporidiosis is recognized as one of the leading causes of childhood diarrhea in African countries. It has dramatic adverse effects on child growth and development and causes increased mortality on a continent where HIV, poverty, and lack of sanitation and infrastructure increase the risk of cryptosporidial waterborne infection.

    Implicit in the African Renaissance is the synergy between government, the private sector, the educated minority and the disadvantaged majority. For this concept to work, belief and commitment must arise first from the African individual, whatever his or her potential contribution may be. The geosciences in South Africa provide a currently vibrant example of such cooperation, which has the potential to contribute significantly to the upliftment of the country and its neighbouring states. Based largely on personal interviews with various role players, from the Presidency of South Africa, through ministerial levels, the corporate sector and down to the individual, we present a spectrum of viewpoints and initiatives which are starting to result in practical implementation of the African revival. An end to conflict and xenophobia, the entrenchment of democratic government and corporate expression of the entrepreneurial spirit are essential to provide the framework within which the individual African can become a "Renaissance Man or Woman".

    Recombination, together with mutation, gives rise to genetic variation in populations. Here we leverage the recent mixture of people of African and European ancestry in the Americas to build a genetic map measuring the probability of crossing over at each position in the genome, based on about 2.1 million crossovers in 30,000 unrelated African Americans. At intervals of more than three megabases it is nearly identical to a map built in Europeans. At finer scales it differs significantly, and we identify about 2,500 recombination hotspots that are active in people of West African ancestry but nearly inactive in Europeans. The probability of a crossover at these hotspots is almost fully controlled by the alleles an individual carries at PRDM9 (P value < 10(-245)). We identify a 17-base-pair DNA sequence motif that is enriched in these hotspots, and is an excellent match to the predicted binding target of PRDM9 alleles common in West Africans and rare in Europeans. Sites of this motif are predicted to be risk loci for disease-causing genomic rearrangements in individuals carrying these alleles. More generally, this map provides a resource for research in human genetic variation and evolution.

    2016-01-01

    This review is an update to the American College of Gastroenterology (ACG) Committee on Minority Affairs and Cultural Diversity's paper on colorectal cancer (CRC) in African Americans published in 2005. Over the past 10 years, the incidence and mortality rates of CRC in the United States has steadily declined. However, reductions have been strikingly much slower among African Americans who continue to have the highest rate of mortality and lowest survival when compared with all other racial groups. The reasons for the health disparities are multifactorial and encompass physician and patient barriers. Patient factors that contribute to disparities include poor knowledge of benefits of CRC screening, limited access to health care, insurance status along with fear and anxiety. Physician factors include lack of knowledge of screening guidelines along with disparate recommendations for screening. Earlier screening has been recommended as an effective strategy to decrease observed disparities; currently the ACG and American Society of Gastrointestinal Endoscopists recommend CRC screening in African Americans to begin at age 45. Despite the decline in CRC deaths in all racial and ethnic groups, there still exists a significant burden of CRC in African Americans, thus other strategies including educational outreach for health care providers and patients and the utilization of patient navigation systems emphasizing the importance of screening are necessary. These strategies have been piloted in both local communities and Statewide resulting in notable significant decreases in observed disparities. PMID:27467183

    Full Text Available There have been questions as to whether African Philosophy exists or not. European scholars and some African scholars are at the opposite end of this scholarly debate. The result is the production of various works by Odera Oruka, Omoregbe, Bordunrin, Wright, Maurier and others espousing their views for or against the existence of African Philosophy. This paper attempts to show the existence of a unique Philosophy that deserves to be recognized and rightly known as African Philosophy. It shows the existence of African Logic using examples from two Niger-Delta societies. The paper begins with the concept of Logic in African thought system, the natural nature of it and it’s applicability to these communities especially as it permeates every aspect of the African way of life. The Ibani and Ogoni societies in the Niger-Delta were used as case studies.

  14. An African-American family with dystonia.

    Puschmann, Andreas; Xiao, Jianfeng; Bastian, Robert W; Searcy, Jill A; LeDoux, Mark S; Wszolek, Zbigniew K

    2011-08-01

    The genetic cause of late-onset focal and segmental dystonia remains unknown in most individuals. Recently, mutations in Thanatos-associated protein domain containing, apoptosis associated protein 1 (THAP1) have been described in DYT6 dystonia and associated with some cases of familial and sporadic late-onset dystonia in Caucasians. We are not aware of any previous descriptions of familial dystonia in African-Americans or reports of THAP1 mutations in African-Americans. Herein, we characterize an African-American (AA) kindred with late-onset primary dystonia, clinically and genetically. The clinical phenotype included cervical, laryngeal and hand-forearm dystonia. Symptoms were severe and disabling for several family members, whereas others only displayed mild signs. There were no accompanying motor or cognitive signs. In this kindred, age of onset ranged from 45 to 50 years and onset was frequently sudden, with symptoms developing within weeks or months. DYT1 was excluded as the cause of dystonia in this kindred. The entire genomic region of THAP1, including non-coding regions, was sequenced. We identified 13 sequence variants in THAP1, although none co-segregated with dystonia. A novel THAP1 variant (c.-237-3G>T/A) was found in 3/84 AA dystonia patient alleles and 3/212 AA control alleles, but not in 5870 Caucasian alleles. In summary, although previously unreported, familial primary dystonia does occur in African-Americans. Genetic analysis of the entire genomic region of THAP1 revealed a novel variant that was specific for African-Americans. Therefore, genetic testing for dystonia and future studies of candidate genes must take genetic background into consideration. PMID:21601506

  15. The evolution of African plant diversity

    Directory of Open Access Journals (Sweden)

    Hans Peter Linder

    2014-07-01

    Full Text Available Sub-Saharan Africa includes some 45,000 plant species. The spatial patterns of this diversity have been well explored. We can group the species into a set of biogeographical regions (largely co-incident with regions defined for terrestrial vertebrate groups. Furthermore, we know that the diversity is unevenly distributed, with southern Africa (especially the south-western tip disproportionally species rich, while the West African interior is disproportionally species poor. However, the origins of this diversity have only been explored for two anomalous African Floras (the Tropic-alpine Flora and the Cape Flora, whereas the origins of the diversity of the other floras are still unknown. Here I argue that six floras, with distinct geographical centres, different extra-African affinities, ages of radiation and radiation rates, can be delimited: the Austro-temperate, Tropic-alpine, Lowland forest, Tropic-montane, Savanna and Arid Floras. The oldest flora may be the Lowland forest Flora, and the most recent is the Tropic-alpine, which probably evolved during the Plio-Pleistocene on the summits of the East Africa volcanoes. My results suggest that the most rapidly radiating flora is the Austro-temperate Flora, while the other floras are all diversifying at more or less the same rate, this is also consistent with the current massive species richness in this flora (about half of the African species richness. The Austro-temperate Flora appears to be related to the floras of the other southern continents, the Tropic-alpine Flora to that of the Northern Hemisphere, and the four tropical floras to the tropical regions of the other continents, consistent with the theory of phylogenetic niche conservatism. Current African diversity may be the result of the sequential adding of new floras to the continent. Possibly the species poverty especially of the Lowland forest Flora may be the result of the spread of C4 grasslands and associated regular fires.

  16. In Search of Greater Unity: African States and the Quest for an African Union Government

    Directory of Open Access Journals (Sweden)

    Sharkdam Wapmuk

    2009-12-01

    Full Text Available The paper examines the notion of an African union government.It argues that the proposal for a ‘union government’ has often divided African leaders into different ideological groups. That not withstanding, Africa leaders have had to bury their differences and embrace African unity in the fight against colonialism and racist rule. Under the OAU, these constituted the rallying point for African leaders until the last vestiges of colonialism and racist rule were crushed in South Africa in 1994. More than 40 years after the idea of unification of Africa was first suggested by Kwame Nkrumah of Ghana; the Libyan leader, President Muammar Ghaddafi re-tabled the proposal. However, the machinations being employed by the Libyan leader to actualise his vision of a union government in Africa under a single president necessitate a deeper exploration of the idea. The paper observed that the challenges to achieving a union government are numerous at this time. In addition toproblem of lack of integration at national levels and poor funding of the AU; Africa is presently faced with several problems bordering on violent conflicts, poverty and underdevelopment, economic development, diseases such as HIV-AIDS, malaria, tuberculosis, and bad governance amongst others. The paper concludes that these challenges should serve as the rallying point for African leaders at this time and not the political machinations of some leaders on the continent.

Bentham’s work, in which the subdivisions of the genus were for the first time given names, is considered and his two series into which the African species fall are reproduced. The characters employed by various workers to divide the African species into two main groups are mentioned and the advantages of using each of these characters for the first dichotomy in a key are discussed. Recent work on pollen morphology and seedling morphology is correlated with general morphology. A proposal put forward by Guinet to divide Acacia into three large genera on the basis of pollen morphology is briefly discussed. Certain modifications to Bentham's series Vulgares and Gummiferae are suggested.

  19. The Offshore East African Rift System

    Franke, D.; Klimke, J.; Jokat, W.; Stollhofen, H.; Mahanjane, S.

    2014-12-01

    Numerous studies have addressed various aspects of the East African Rift system but surprisingly few on the offshore continuation of the south-eastern branch of the rift into the Mozambique Channel. The most prominent article has been published almost 30 years ago by Mougenot et al. (1986) and is based on vintage seismic data. Several studies investigating earthquakes and plate motions from GPS measurements reveal recent deformation along the offshore branch of the East African Rift system. Slip vectors from earthquakes data in Mozambique's offshore basins show a consistent NE direction. Fault plane solutions reveal ~ E-W extensional failure with focal depth clustering around 19 km and 40 km, respectively. Here, we present new evidence for neotectonic deformation derived from modern seismic reflection data and supported by additional geophysical data. The modern rift system obviously reactivates structures from the disintegration of eastern Gondwana. During the Jurassic/Cretaceous opening of the Somali and Mozambique Basins, Madagascar moved southwards along a major shear zone, to its present position. Since the Miocene, parts of the shear zone became reactivated and structurally overprinted by the East African rift system. The Kerimbas Graben offshore northern Mozambique is the most prominent manifestation of recent extensional deformation. Bathymetry data shows that it deepens northwards, with approximately 700 m downthrown on the eastern shoulder. The graben can be subdivided into four subbasins by crosscutting structural lineaments with a NW-SE trend. Together with the N-S striking graben-bounding faults, this resembles a conjugate fault system. In seismic reflection data normal faulting is distinct not only at the earthquake epicenters. The faults cut through the sedimentary successions and typically reach the seafloor, indicating ongoing recent deformation.

    This paper conceptualizes intergenerational occupational mobility between the farm and non-farm sectors in five African countries, measures it using nationally representative household survey data, and analyzes its determinants through a comparative method based on pooled logit regressions. We first analyze intergenerational gross mobility. Until the end of the 1980s, intergenerational flows toward the non-farm sector are high in Cote d'Ivoire and Guinea, flows toward the farm sector are more...

    1998-04-01

    A 3-yr-old male African hedgehog (Atelerix albiventris) had anorexia and weight loss for 1 wk before its death. The colon and mesocolon were diffusely infiltrated by a neoplastic proliferation of round cells with plasmacytoid features. A diagnosis of intestinal plasmacytoma was made and confirmed by electron microscopy. No other organs appeared to be affected. This is the first description of intestinal plasmacytoma in a hedgehog.

    The number of migrants to the United States from Africa has grown exponentially since the 1930s. For the first time in America's history, migrants born in Africa are growing at a faster rate than migrants from any other continent. The composition of African-origin migrants has also changed dramatically: in the mid-twentieth century, the majority were white and came from only three countries; but today, about one-fifth are white, and African-origin migrants hail from across the entire continent. Little is known about the implications of these changes for their labor market outcomes in the United States. Using the 2000-2011 waves of the American Community Survey, we present a picture of enormous heterogeneity in labor market participation, sectoral choice, and hourly earnings of male and female migrants by country of birth, race, age at arrival in the United States, and human capital. For example, controlling a rich set of human capital and demographic characteristics, some migrants-such as those from South Africa/Zimbabwe and Cape Verde, who typically enter on employment visas-earn substantial premiums relative to other African-origin migrants. These premiums are especially large among males who arrived after age 18. In contrast, other migrants-such as those from Sudan/Somalia, who arrived more recently, mostly as refugees-earn substantially less than migrants from other African countries. Understanding the mechanisms generating the heterogeneity in these outcomes-including levels of socioeconomic development, language, culture, and quality of education in countries of origin, as well as selectivity of those who migrate-figures prominently among important unresolved research questions.

    Sellers, R M; Kuperminc, G P; Damas, A

    1997-10-01

    The present study provides a descriptive analysis of four areas of African American women student athletes' college life experiences: academic performance; alienation and abuse; perceived social advantage as the result of athletics; and life satisfaction. Multivariate comparisons were made between the four areas of college life experiences of 154 African American women student athletes and 793 White women student athletes, 250 African American women nonathletes, and 628 African American men student athletes from a national sample of 39 NCAA Division I universities. Overall, African American women student athletes are performing adequately academically, integrating socially within the university, perceiving some social advantage as the result of being athletes, and are fairly satisfied with their life. Their experiences seem most consistent with African American women nonathletes. Results are discussed in the context of potential policy recommendations as well as the need for more research on this particular population. PMID:9485580

  15. Rethinking "relevance": South African psychology in context.

    Science.gov (United States)

    Long, Wahbie

    2013-02-01

    This article examines the phenomenon known as the "relevance debate" in South African psychology. It begins with a historical overview of the contours of the discipline in that country before describing the controversy's international dimensions, namely, the revolutionary politics of 1960s higher education and the subsequent emergence of cognate versions of the debate in American, European, and "Third World" psychology. The article then details how South Africa's "relevance" project enjoyed a special affinity with an assortment of ethnic-cultural, national, and continental myths and metaphors, all of which served the interests of the political formations of the day. It discusses how, in present-day South Africa, the intelligentsia has become an important catalyst for the so-called African Renaissance, which seeks to provide "relevant" solutions for the regeneration of African society. However, the global hegemony of what began in the 1970s as a "second academic revolution," aided by the lifting of the academic boycott of South Africa, has blunted the once critical edge of "relevance" discourse. A new mode of knowledge production now holds sway, the outcome of a dramatic reformulation of the capitalist manifesto in which the values of the "May 68" generation have been hijacked by a managerialist rationality. In light of the capitalization of the knowledge-production enterprise, it is concluded that the idiom of "relevance" has outlived its usefulness. PMID:23421936

    Full Text Available Background : Characteristics of intracranial aneurysms display ethnic variations. Data on this disease from the African continent is scarce and often conflicting. Aim : To describe site, age and gender distribution of intracranial aneurysms among Kenyans. Study Design and Setting : Retrospective study at Kenyatta National Hospital, Kenya. Materials and Methods: All records of black African patients with a diagnosis of intracranial aneurysms seen at Kenyatta National Hospital, the largest referral hospital in the Eastern and Central African region, over the period from January 1998 to December 2007 were examined for site, age and gender distribution. The data gathered were coded, analyzed with SPSS 11.50. Results : Fifty-six cases of intracranial aneurysms were analyzed. The posterior communicating artery was the most affected (35.7%, followed by the anterior communicating artery (26.8%, while the posterior cerebral artery was the least affected (2%. Multiple aneurysms were present in 2%. The mean age at presentation was 50.9 years (range 21-80 years and the gender distribution was equal. Conclusions : Intracranial aneurysms among Kenyans occur most commonly on the posterior communicating artery, in young individuals, and without gender bias. The distribution differs from that described in the literature and this requires search for risk factors.

    2016-07-01

    Cystic fibrosis (CF; OMIM 219700) is a life-shortening and costly autosomal recessive disease that has been most extensively studied in individuals of Caucasian descent. There is ample evidence, however, that it also affects other ethnicities. In Africa there have been several reports of CF, but there has been no concerted effort toward establishing the molecular epidemiology of this disease on the continent, which is the first step toward outlining a public health strategy to effectively address the needs of these patients. A literature search revealed reports from only 12 of the 54 African states on the molecular analysis of the mutations present in suspected CF patients, resulting in the identification of 79 mutations. Based on previous functional investigations, 39 of these cause CF, 10 are of varying clinical consequence, 4 have no associated evidence regarding whether they cause CF, 4 are synonymous, 5 are novel, and 21 are unique to Africa. We propose that CF be more thoroughly investigated on the continent to ensure that the public health needs of African CF patients-both those in Africa and those of African descent living elsewhere-are met.Genet Med 18 7, 653-662.

    Micropropagation is an important tool for rapid multiplication and the creation of genetic variability in African violets (Saintpaulia ionantha Wendl.). Successful in vitro propagation depends on the specific requirements and precise manipulation of various factors such as the type of explants used, physiological state of the mother plant, plant growth regulators in the culture medium, and growth conditions. Development of cost-effective protocols with a high rate of multiplication is a crucial requirement for commercial application of micropropagation. The current chapter describes an optimized protocol for micropropagation of African violets using leaf explants obtained from in vitro grown plants. In this process, plant regeneration occurs via both somatic embryogenesis and shoot organogenesis simultaneously in the explants induced with the growth regulator thidiazuron (TDZ; N-phenyl-N'-1,2,3-thidiazol-5-ylurea). The protocol is simple, rapid, and efficient for large-scale propagation of African violet and the dual routes of regeneration allow for multiple applications of the technology from simple clonal propagation to induction or selection of variants to the production of synthetic seeds.

    Norms for African American elders on the Wechsler Memory Scale-Revised (WMS-R) were derived from a sample of 309 community-dwelling individuals participating in Mayo's Older African Americans Normative Studies (MOAANS). Normative estimates are provided for traditional WMS-R subtest scores and for supplemental procedures to evaluate forgetting rates and recognition memory. Tables are provided to convert raw WMS-R subtest and supplemental scores to age-corrected scaled scores. These may be further adjusted for years of education, if desired, by applying regression-based corrections. We anticipate that these data will enhance the diagnostic utility and clinical interpretation of WMS-R performance in older African Americans.

    Genome-wide association (GWA) studies have identified common variants that are associated with a variety of traits and diseases, but most studies have been performed in European-derived populations. Here, we describe the first genome-wide analyses of imputed genotype and copy number variants (CNVs) for anthropometric measures in African-derived populations: 1188 Nigerians from Igbo-Ora and Ibadan, Nigeria, and 743 African-Americans from Maywood, IL. To improve the reach of our study, we used imputation to estimate genotypes at approximately 2.1 million single-nucleotide polymorphisms (SNPs) and also tested CNVs for association. No SNPs or common CNVs reached a genome-wide significance level for association with height or body mass index (BMI), and the best signals from a meta-analysis of the two cohorts did not replicate in approximately 3700 African-Americans and Jamaicans. However, several loci previously confirmed in European populations showed evidence of replication in our GWA panel of African-derived populations, including variants near IHH and DLEU7 for height and MC4R for BMI. Analysis of global burden of rare CNVs suggested that lean individuals possess greater total burden of CNVs, but this finding was not supported in an independent European population. Our results suggest that there are not multiple loci with strong effects on anthropometric traits in African-derived populations and that sample sizes comparable to those needed in European GWA studies will be required to identify replicable associations. Meta-analysis of this data set with additional studies in African-ancestry populations will be helpful to improve power to detect novel associations. PMID:20400458

  13. Mandela’s Favourite African Folktales

    Directory of Open Access Journals (Sweden)

    Carmen Concilio

    2014-11-01

    Full Text Available In this essay I would like to examine the selection of African tales that Nelson Mandela took care to leave as heritage to the future generations, not only to children, and not only to African children. The fact that a political leader, ex freedom fighter and political prisoner dedicated his time to the collection and editing of stories from all over the African continent to be addressed to new readers as simple entertainment or as educational tools clearly testifies to the great humanity, culture, and open mindedness of one of the most important men of our times. In his most recent autobiographical writing Conversations With Myself, Mandela claimed his double affiliation to both his own indigenous culture as well as to western culture. Moreover, he recalled with affection a dear pastime of his childhood:After supper we would listen enthralled to my mother and sometimes my aunt telling us stories, legends, myths and fables which have come down from countless generations, and all of which tended to stimulate the imagination and contained some valuable moral lesson. (p. 10Thus, it is not surprising that such a charismatic public figure, as Mandela has been, was also interested in- and worried about- the future survival of a cluster of traditional folktales with their lively, specific and “valuable moral lesson”. It is my intention to verify if there might be a dialogue between the western tradition of folktales where animals are protagonists and speak as anthropomorphic figures and the facets of the African traditions and cultures from which Mandela draws inspiration. Among the critical tools on this topic, Tess Cosslett’s Talking Animals in British Children’s Fiction (2006 seems to provide a useful starting point, together with the latest studies in the volume Dall’ABC a Harry Potter (2011, among others. Moreover, aspects of “orature” will be discussed with reference to the stories chosen by Nelson Mandela. Finally, an attempt will

    This article examines factors responsible for the stark racial disparities in HIV infection in the U.S. and the now concentrated epidemic among African Americans. Sexual network patterns characterized by concurrency and mixing among different subpopulations, together with high rates of other sexually transmitted infections, facilitate dissemination of HIV among African Americans. The social and economic environment in which many African Americans live shapes sexual network patterns and increases personal infection risk almost independently of personal behavior. The African American HIV epidemic constitutes a national crisis whose successful resolution will require modifying the social and economic systems, structures, and processes that facilitate HIV transmission in this population.

  16. As below, so above: A perspective on African Theology

    Directory of Open Access Journals (Sweden)

    Arno Meiring

    2007-05-01

    Full Text Available African theology can be understood as a theology from below – or rather, “as below, so above”. This phrase not only reflects the concept of ubuntu and the African partiality towards horizontal relationships, but may help explain African perspectives on shame and guilt, sin and reconciliation, liberation, the ancestors and eschatology. Subsequently, there seems to be some concurrence between African theology and Western postmodern theology. Although these theologies challenge traditional theology, and should in turn be scrutinized, they may offer useful and valid ways of thinking and speaking about God.

  17. North African populations carry the signature of admixture with Neandertals.

    Directory of Open Access Journals (Sweden)

    Federico Sánchez-Quinto

    Full Text Available One of the main findings derived from the analysis of the Neandertal genome was the evidence for admixture between Neandertals and non-African modern humans. An alternative scenario is that the ancestral population of non-Africans was closer to Neandertals than to Africans because of ancient population substructure. Thus, the study of North African populations is crucial for testing both hypotheses. We analyzed a total of 780,000 SNPs in 125 individuals representing seven different North African locations and searched for their ancestral/derived state in comparison to different human populations and Neandertals. We found that North African populations have a significant excess of derived alleles shared with Neandertals, when compared to sub-Saharan Africans. This excess is similar to that found in non-African humans, a fact that can be interpreted as a sign of Neandertal admixture. Furthermore, the Neandertal's genetic signal is higher in populations with a local, pre-Neolithic North African ancestry. Therefore, the detected ancient admixture is not due to recent Near Eastern or European migrations. Sub-Saharan populations are the only ones not affected by the admixture event with Neandertals.

Involvement of managers is contributing up to 80% of the total costs of white collar crime. In order to try to understand the situation, the current South African managerial climate is analysed.This analysis clearly indicates that South African managers function in stressful circumstances which can give rise to unethical behaviour. A theoretical model for ethical behaviour is therefore discussed and used as a basis for practical suggestions in order to improve the situation.

    Full Text Available Duration of nocturnal melatonin secretion, a marker of “biological night” that relates to sleep duration, is longer in winter than in summer in patients with seasonal affective disorder (SAD, but not in healthy controls. In this study of African and African American college students, we hypothesized that students who met criteria for winter SAD or subsyndromal SAD (S-SAD would report sleeping longer in winter than in summer. In addition, based on our previous observation that Africans report more “problems” with change in seasons than African Americans, we expected that the seasonal changes in sleep duration would be greater in African students than in African American students. Based on Seasonal Pattern Assessment Questionnaire (SPAQ responses, African American and African college students in Washington, D.C. (N = 575 were grouped into a winter SAD/S-SAD group or a no winter diagnosis group, and winter and summer sleep length were determined. We conducted a 2 (season × 2 (sex × 2 (ethnicity × 2 (winter diagnosis group ANCOVA on reported sleep duration, controlling for age. Contrary to our hypothesis, we found that African and African American students with winter SAD/S-SAD report sleeping longer in the summer than in the winter. No differences in seasonality of sleep were found between African and African American students. Students with winter SAD or S-SAD may need to sacrifice sleep duration in the winter, when their academic functioning/efficiency may be impaired by syndromal or subsyndromal depression, in order to meet seasonally increased academic demands.

  4. African Psychology: The Psychological Adjustment of African Women Living in New Zealand

    Directory of Open Access Journals (Sweden)

    Adelowo, Adesayo

    2015-11-01

    Full Text Available Social representation theory is a social psychological framework of concepts and ideas relevant to studying psychosocial phenomena in modern societies. It suggests that social psychological phenomenon and processes can only be properly understood when they are anchored in history, culture and macro social conditions. Therefore, social representations are carriers of collective memories of social groups which are adequate for shaping the present through the past; while using the past to meet the demands of the present, which enables social groups to continue through time. Social groups are distinct in terms of their understanding of social phenomenon and other forms of action which in turn constitute their identity. In this article, I present an African psychological framework which represents African people’s worldview. Further to this, is my experience as a doctoral student, exploring the psychological adjustment of African women living in New Zealand. I reflect on why the framework that I had used in my research were deemed inadequate to be used as psychological principles, because they did not correspond with a Western lens of understanding behaviour, actions and social reality. I conclude that the outcome of my study shows the reification and legitimization of Western psychology over African psychology. This article provides a possibility for a critical account of unequal social relations between Western psychology and Indigenous psychology, and exposes the issue of power and resistance embedded in the heart of social representation theories as it relates to psychology.

  5. Emigration dynamics of eastern African countries.

    Science.gov (United States)

    Oucho, J O

    1995-01-01

    This examination of emigration dynamics focuses on 13 countries extending from Eritrea to Zimbabwe and Mozambique on the eastern African mainland and on 5 Indian Ocean island nations. The first part of the study looks at the temporal, spatial, and structural perspectives of emigration dynamics. Part 2 considers international migration in the region according to Appleyard's typology (permanent settlers, labor migration, refugees, and illegal migrants) with the additional category of return migration. Measurement issues in emigration dynamics are discussed in part 3, and the demographic/economic setting is the topic of part 4. The demographic factors emphasized include spatial distribution, population density, population structure, population dynamics, demographic transition, and the relationship between internal and international migration. Other major topics of this section of the study are the economic base, the human resource base, population and natural resources, the sociocultural context (emigration, chain migration, return migration, and migration linkages and networks), political factors (including human rights, minority rights and security, regional integration and economic cooperation, and the impact of structural adjustment programs), and a prediction of future emigration dynamics. It is concluded that refugee flows remain a major factor in eastern African countries but the development of human resources in the northern portion of the region indicates development of potential labor migration from this area. Data constraints have limited measurement of emigration in this region and may contribute to the seeming indifference of most eastern African countries to emigration policies. Emigration in this region has been triggered by deteriorating economic and political conditions and is expected to increase. PMID:12347007

  6. African fossil tali: further multivariate morphometric studies.

    Lisowski, F P; Albrecht, G H

    1976-07-01

    Analysis of measurements from the tali of 21 individual fossil primates from Africa shows that the specimens fall into five clearly defined groups. Accordingly, these specimens have been included as groups along with extant species in a subsequent canonical analysis thus allowing the fossils to play their part in the determination of the canonical separations. The results of this procedure show that the five fossil groups lie in a part of the canonical space not occupied by any extant African primate. Their positions are between the envelope of Asiatic apes (Hylobates and Pongo) and the envelope of African forms near the edge which contains Pan and Papio. One fossil group is so similar to Hylobates that its talus may have functioned in locomotion in a parallel manner. Others lie near to Pongo in directions proceeding towards Pan and Papio and it is possible that this similarity may indicate remnants of morphological adaptation for climbing in these fossils. At the same time, however, individual specimens are closer to one or another of the extant groups and this considerable spread suggests that the locomotor adaptations as evidenced by talar morphology, of the primate fauna in Africa, may have been very different from those of the present day. This would not the inconsistent with the different habitats, floras and non-primate faunas that may have characterized the East African scene at these earlier times. Particular fossils from Olduvai and Kromdraai that are supposed to be australopithecine and therefore bipeds, are confirmed (Oxnard, '72; Lisowski et al., '74) as being totally different from man in their talar morphology and essentially rather similar to the majority of the other fossil tali examined.

  7. African Independent Churches in Zambia (Lusaka

    Directory of Open Access Journals (Sweden)

    Mildnerová Kateřina

    2014-12-01

    Full Text Available The African Independent churches (AICs in Zambia, as elsewhere in Africa, from their very beginning formed a protest movement against the cultural imperialism undertaken by the missionary representatives of the historic mission churches and also played an important role in the anti-colonial political struggles. In Zambia, the early AICs were closely related to witchcraft eradication movements such as the Mchape, or socially and politically oriented prophet-healing churches such as The Lumpa church of Alice Lenshina. Since the 1970s and in particular in the 1990s the Christianity in Zambia has been significantly marked by the proliferation of the African Independent Churches - both of Pentecostal and prophet-healing type. These churches that started mushrooming particularly in urban settings became part of the strengthening charismatic movement, particularly within Protestantism. A typical feature of AICs is focus on spiritual healing and religious syncretism - the local traditional customs and beliefs in dangerous ghosts, ancestral spirits, or witches are placed within the biblical religious framework where the Holy Spirit (Muzimu Oyela is considered to be the only source of healing whereas other ‘inferior spirits’ are labelled as demons. The traditional methods of healing are creatively combined with Christian healing by means of prayers, spiritual blessings, laying on of hands on patients and demon exorcism - it is believed that only a body rid of bad spirits can receive the Holy Spirit, and thus be healed. The paper draws on both secondary literature concerning African Independent Churches and primary data issued from fieldwork in Lusaka (2008-2009.

  4. The Great Migration and African-American Genomic Diversity.

    Directory of Open Access Journals (Sweden)

    Soheil Baharian

    2016-05-01

    Full Text Available We present a comprehensive assessment of genomic diversity in the African-American population by studying three genotyped cohorts comprising 3,726 African-Americans from across the United States that provide a representative description of the population across all US states and socioeconomic status. An estimated 82.1% of ancestors to African-Americans lived in Africa prior to the advent of transatlantic travel, 16.7% in Europe, and 1.2% in the Americas, with increased African ancestry in the southern United States compared to the North and West. Combining demographic models of ancestry and those of relatedness suggests that admixture occurred predominantly in the South prior to the Civil War and that ancestry-biased migration is responsible for regional differences in ancestry. We find that recent migrations also caused a strong increase in genetic relatedness among geographically distant African-Americans. Long-range relatedness among African-Americans and between African-Americans and European-Americans thus track north- and west-bound migration routes followed during the Great Migration of the twentieth century. By contrast, short-range relatedness patterns suggest comparable mobility of ∼15-16km per generation for African-Americans and European-Americans, as estimated using a novel analytical model of isolation-by-distance.

    Full Text Available Pseudoachondroplasia is an autosomal dominant skeletal dysplasia that results in disproportionately short stature, severe brachydactyly with strikingly lax small joints, malalignments of the lower limbs, and characteristic radiological features. Although named ‘false achondroplasia’, the entity is a distinct condition, in which affected individuals are born with normal length and have a normal facies, but is often only recognised after the age of 2 years, when the disproportion and waddling gait become evident. We report on an affected South African father and daughter, and highlight their clinical and radiographic features.

According to historical records, China had contacts with Africa as earty as the third century B.C. In the Han Dynasty (206 B.C.-A.D. 220). Exchanges became frequent In the Tang Dynasty (618-907) and Song Dynasty (960-1279).

    The aim of this paper is to describe the most notable features and background of English in East Africa. That is: Kenya, Tanzania and Uganda. For this to be possible, English as a second language has to be discussed, since English is the second, third, or even fourth language of East Africa’s inhabitants. The development and characteristics of English in Africa generally will thus be discussed before the discussion turns to East African English with a special emphasis on Kenya. One of the ...

  19. Tenancy and African American Marriage in the Postbellum South.

    Bloome, Deirdre; Muller, Christopher

    2015-10-01

    The pervasiveness of tenancy in the postbellum South had countervailing effects on marriage between African Americans. Tenancy placed severe constraints on African American women's ability to find independent agricultural work. Freedwomen confronted not only planters' reluctance to contract directly with women but also whites' refusal to sell land to African Americans. Marriage consequently became one of African American women's few viable routes into the agricultural labor market. We find that the more counties relied on tenant farming, the more common was marriage among their youngest and oldest African American residents. However, many freedwomen resented their subordinate status within tenant marriages. Thus, we find that tenancy contributed to union dissolution as well as union formation among freedpeople. Microdata tracing individuals' marital transitions are consistent with these county-level results. PMID:26223562

    Full Text Available The search, what constitutes the pure identity of African Literature, continues among historians and literary scholars. In this paper, we try to unmask a silent literary weapon which is at the disposal of many conscious African writers perhaps unconsciously anyway. The purpose is to make understanding of literature especially African literature easier. Our emphasis is on the common themes expressed in the selected poems. The new historicism, which upholds that writing history is a matter of interpretations, not entirely facts, is the theoretical approach on which this paper is premised. The paper ends with a conclusion that lamentation is a literary weapon through which many African writers create or enact the required consciousness on their readers because the device is a constant decimal in African literary creations across generations: from its inception (pre-colonial period through the colonial and the post-colonial era (till date.

    2015-03-01

    Full Text Available The scientific study of near-death experience (NDE teaches that NDE does not entail evidence for life after death, but a study of NDE from an African perspective implies that NDE could serve as a yardstick which supports African traditional beliefs concerning death and resurrection. Using references from Ancient-Egyptian afterlife beliefs and those of the Yorubas of Nigeria, I argue that, for Africans, the percipients of NDE did not only come close to death but are regarded as having truly died. The purpose of this research is to initiate an African debate on the subject and to provide background-knowledge about NDE in Africa for counsellors who counsel NDE percipients that are Africans.

    African Americans have exceptionally high rates of hypertension and hypertension related complications. It is commonly reported that the blood pressure lowering efficacy of renin angiotensin system(RAS) inhibitors is attenuated in African Americans due to a greater likelihood of having a low renin profile. Therefore these agents are often not recommended as initial therapy in African Americans with hypertension. However, the high prevalence of comorbid conditions, such as diabetes, cardiovascular and chronic kidney disease makes treatment with RAS inhibitors more compelling. Despite lower circulating renin levels and a less significant fall in blood pressure in response to RAS inhibitors in African Americans, numerous clinical trials support the efficacy of RAS inhibitors to improve clinical outcomes in this population, especially in those with hypertension and risk factors for cardiovascular and related diseases. Here, we discuss the rationale of RAS blockade as part of a comprehensive approach to attenuate the high rates of premature morbidity and mortality associated with hypertension among African Americans.

    2016-06-01

    African American grandparent caregiving is increasing, and evidence shows that grandparent caregiving influences health and its management. As older adults age, their potential of experiencing chronic pain increases, and this is profound given that physiological research shows that African Americans, aside from aging, may have a predisposition for developing chronic pain. Research shows older African Americans experience significant chronic pain, but few have discussed the implications of managing chronic pain in older African Americans who have added parental responsibility. Many older African Americans receive home healthcare services and there is a unique role for home healthcare clinicians in caring for this vulnerable population. This article discusses the impact of pain on caregiving, challenges in pain management, and practice and policy implications to assist home healthcare clinicians maintain the safety and protection of both the older grandparent and grandchildren.

    Does cognitive ability always correlate with a positive fitness consequence? Previous research in both vertebrates and invertebrates provides mixed results. Here, we compare the learning and memory abilities of Africanized honeybees ( Apis mellifera scutellata hybrid) and European honeybees ( Apis mellifera ligustica). The range of the Africanized honeybee continues to expand, superseding the European honeybee, which led us to hypothesize that they might possess greater cognitive capabilities as revealed by a classical conditioning assay. Surprisingly, we found that fewer Africanized honeybees learn to associate an odor with a reward. Additionally, fewer Africanized honeybees remembered the association a day later. While Africanized honeybees are replacing European honeybees, our results show that they do so despite displaying a relatively poorer performance on an associative learning paradigm.

  5. Women and the social construction of gender in African development.

    1996-01-01

    Because a footnote of Marxism teaches that capitalism must first destroy primitive cultures that lack a dynamic social change mechanism and then rejuvenate them as modern industrialized states, the economic and cultural bases of social relationships in developing countries have been deemed irrelevant. In a similar way, Western feminist paradigms fail to acknowledge epistemological differences from those of African women. This article explores these contradictions and analyzes social change mechanisms within the Igbo culture in Africa that were stunted by colonialism. The first topic considered is the relationship of African literature (using Toni Morrison's "Beloved" as a point of reference) with sustainable African development and African women. The remainder of the article is devoted to an examination of the role of women in light of precolonial and colonial literary traditions. It is noted that continued use of Western feudal and capitalist terms for self-identification alienates Africans from Africa's problems. Traditional African thought assigned women the power to feed the family and to serve as protectors of children and society, and ancestral wisdom directed how societies responded to threats, took charge of their world, and resolved conflict. Problems faced by contemporary African researchers are shown to center on the dilemma faced by those who wish to design a program that analyzes the content of African development and provides contemporary solutions without completely deriving the program completely from contemporary thought. It is, thus, concluded that redefinition of the African development agenda must involve recognition of the essential role of African women as a change agent and a rearticulation of the male role within traditional thought.

  6. 5-HTTLPR Polymorphism: Analysis in South African Autistic Individuals

    2010-06-01

    The serotonin transporter promoter length polymorphism (5-hydroxytryptamine transporter length polymorphism; 5-HTTLPR) has long been implicated in autism and other psychiatric disorders. The use of selective serotonin reuptake inhibitors (SSRIs) has a positive effect on treating some symptoms of autism. The effects of these drugs vary in individuals because of the presence of the S or L allele of 5-HTTLPR. Studies performed on various autistic populations have found different allele frequencies for the L and S alleles. Allele frequencies and genotypes of the South African autistic populations (African, mixed, and Caucasian) were compared with matching South African ethnic control populations. The *S/*S genotype was found to be highly significantly associated with all the South African autistic ethnic populations. In the South African African population the *S/*S genotype was present in 7 (33%) of the autistic individuals but in none of the control subjects, yielding infinitely large odds of developing autism. The odds of developing autism with the *S/*S genotype compared to the *L/*L genotype increased 10.15-fold in the South African mixed group and 2.74-fold in the South African Caucasian population. The allele frequency of the South African autistic population was also compared with studies of other autistic populations around the world, and highly significant differences were found with the Japanese, Korean, and Indian population groups. The difference was not significant for the French, German, Israeli, Portuguese, and American groups. This is the first South African study of autistic individuals of different ethnic backgrounds that shows significant differences in allele and genotype frequencies of 5-HTTLPR. The results of this study open new avenues for investigating the role of transmission of the L and S alleles in families with autism in South Africa.

    2011-08-01

    Full Text Available This paper attempts to appraise African filmmaking and the content of African films from a Nigerian film audience perspective. The study specifically explores the disposition of the audience towards contemporary African filmmaking for home video and cinema entertainment as well as the content of African films. The study used a qualitative questionnaire to determine the perspectives of residents in Lagos as members of the Nigerian film audience. The study found the perception of the content of contemporary African films, particularly home videos, to vary among the film audience. Opinion largely favoured a new orientation towards a de-emphasis on obscene scenes, rituals, fetish practices, violent crimes and display of partial or total nudity in the content of African films. The study, therefore, recommends that regulatory bodies set up in most African countries, such as the Nigerian Film and Video Censors Board, should own up to their responsibilities in terms of ensuring strict compliance of African film makers or producers with rules and regulations guiding film production, content of films and exposure guidelines.

  12. African Fish Biodiversity, Fishbase and Fishculture

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available At present, about 28 600 fish species are considered valid, whilst the total number is estimated at 30 000 to 35 000. For Africa, about 3 000 valid fresh- and brackish water species are currently recognized. Conserving the biodiversity of these fishes and at the same time managing their exploitation in a sustainable way is a difficult exercise. In sub-Saharan Africa, the importance of aquaculture is not very high. Nonetheless, 18 different species are used commercially, of which six have a non-African origin. Documenting and characterizing the ichthyodiversity is vital for conservation and sustainable development purposes. The presence of a large collection, a specialised library and a considerable know-how in the Africa Museum has led to various revisions, checklists, species (redescriptions and regional guides. All the information on African fishes is currently being entered in FishBase, a huge freely accessible database with information on the taxonomy, ecology and various other aspects of the biology of fishes, based on scientific publications and reviewed by specialists. FishBase also includes high quality tools for applied research on fishes, such as a disease wizard, biogeography tools, trophic pyramids, and the species invasiveness tool.

    ENGLISH ABSTRACT: Many South African companies are adopting the shared services methodology because this structure has led to lower operating costs, greater business efficiency, and improved internal service quality in international companies. Part of a doctoral study on shared services in South African companies shows that their business unit managers have not yet experienced positive rewards from their shared services. This article reports on this study, and suggests a larger-scale research project to validate these findings and to investigate the reasons for the poor performance.

  14. The Clean Development Mechanism. An African Delusion?

    Energy Technology Data Exchange (ETDEWEB)

    2000-11-01

    The Clean Development Mechanism (CDM) is one of the three flexible mechanisms introduced in the Kyoto Protocol to the United Nations Framework Convention on Climate Change, as a co-operative instrument to promote sustainable development in the developing countries along with cost-effective greenhouse gas mitigation. It has emerged as one of the most attractive instruments for the African countries, which view this new mechanism as an opportunity to ensure long-term, sustainable and equitable development. The modalities and processes of the CDM have yet to be decided. However, it is predicted that there will be competition between countries at the launch of the mechanism. Considering the circumstances of African countries and the status of climate change-related activities implemented on the continent, it is questionable whether Africa is well enough prepared to benefit from the expected large investments from CDM projects. This paper attempts to highlight some of the key issues related to the prospects of CDM in Africa.

    This overview of psychology in South Africa presents a concise and historical account of its science and practice, from its early origins in the late nineteenth century to the present, and traces seminal influences on the discipline. It is a review of how psychology in South Africa developed over more than a century to become one of the most popular subjects in universities and an established and recognized profession, whose members play a variety of roles in the South African polity and larger society. The impact that apartheid racism had on key aspects of psychology's development is traversed, and the influences that previous ruling party politics had on professional psychological organizations are delineated. The unification of psychology under the Psychological Society of South Africa, a few months before the advent of democracy in South Africa, is explicated. The protection of the title of psychologist in law and certain other changes in the legislative environment, enabling a greater role for psychologists, are reported. The primary research sites for psychology and its funding and the main university psychology programs are described, as are the requirements for registration and licensure. The genesis and the importance of the work of internationally acclaimed South African psychologists, such as J. Wolpe and A. A. Lazarus, are contextualized. With the increased participation of progressive black psychologists in leadership and research in the past two decades, a transformed psychology has the potential to play a significant role in addressing human issues confronting South Africa.

    From 1994 to 1999, 16 captive African hedgehogs (Atelerix albiventris), from among 42 necropsy cases, were diagnosed with cardiomyopathy. The incidence of cardiomyopathy in this study population was 38%. Fourteen of 16 hedgehogs with cardiomyopathy were males and all hedgehogs were adult (>1 year old). Nine hedgehogs exhibited 1 or more of the following clinical signs before death: heart murmur, lethargy, icterus, moist rales, anorexia, dyspnea, dehydration, and weight loss. The remaining 7 hedgehogs died without premonitory clinical signs. Gross findings were cardiomegaly (6 cases), hepatomegaly (5 cases), pulmonary edema (5 cases), pulmonary congestion (4 cases), hydrothorax (3 cases), pulmonary infarct (1 case), renal infarcts (1 case), ascites (1 case), and 5 cases showed no changes. Histologic lesions were found mainly within the left ventricular myocardium and consisted primarily of myodegeneration, myonecrosis, atrophy, hypertrophy, and disarray of myofibers. All hedgehogs with cardiomyopathy had myocardial fibrosis, myocardial edema, or both. Other common histopathologic findings were acute and chronic passive congestion of the lungs, acute passive congestion of the liver, renal tubular necrosis, vascular thrombosis, splenic extramedullary hematopoiesis, and hepatic lipidosis. This is the first report of cardiomyopathy in African hedgehogs. PMID:11021439

In the New Testament, the distinguishing factor is the new being, who is in Christ, being born again by the Holy Spirit, by which man is conformed to the image of his Redeemer and King. The dominant theme in both Testaments is love, which in African ethics is reserved for one's nearest kin, but in Scripture demanded even for one's enemies.

    F2 layer disturbances not related to geomagnetic activity are known as quiet time enhancements (QTEs). The phenomenon of QTEs has not yet been studied over African latitudes. We therefore explore the occurrence of QTEs over Africa in order to expand our knowledge on the behaviour of the ionosphere over this region. Several GPS stations in the middle to equatorial latitudes, during the solar minimum (2009) and near solar maximum (2013), are used. This data was examined for possible trends in variation with solar cycle, season and latitude as well as time of commencement of enhancements. Over the southern mid-latitude region of Africa we have observed that the QTEs are more likely to commence during the night in both solar minimum and maximum, however a slightly larger portion of daytime commencements during solar minimum than during solar maximum were observed. The total number of enhancements for the solar minimum period appears greater than during solar maximum. A seasonal trend is seen with the maximum number of enhancements occurring in summer during solar minimum and in winter during solar maximum. We explore further whether these trends are mirrored or different at low latitude/equatorial African regions.

    2002-01-01

    Traditionally brewed alcoholic beverages are regularly consumed by most ethnic black South Africans. Maize and barley, both of which are used for producing locally brewed alcoholic beer, are frequently contaminated by mycotoxin-producing moulds. The study was undertaken to investigate whether these toxins are present in raw grains and the traditional beers imbibed by the local black African population. It was established that the raw ingredients (sorghum, sorghum malt grains, maize grits), commercially produced traditional beers (Utshwala and Utshwala special) and home-brewed beers (Umqombotha, Isiqatha, Imfulamfula) were contaminated by bacteria and fungi (both yeasts and moulds). The contaminating moulds were isolated and identified. The contaminated samples were analysed for aflatoxins B1, B2, G1 and G2, zearalenone, citrinin, deoxynivalenol, and ochratoxin A using a multi-mycotoxin thin-layer chromatography screening method and the toxins were quantified by high-performance liquid chromatography. Grain samples were infected by. Aspergillus flavus, A. alliaceus, A. clavatus, Penicillium spp., Rhizopus spp. and Mucor spp. Sorghum malt grain samples contained the toxin zear alenone. No mycotoxin-producing fungi were present in the fermented beers but two of six commercial beer samples contained aflatoxins (200 and 400 microg l(-1) and 45% (13 of 29) of the home-brewed beers had zear alenone (range 2.6-426 microg l(-1) and/or ochratoxin A (3-2340 microg l(-1).

    Looking on African perspective in space agriculture may contribute to increase diversity, and enforce robustness for advanced life support capability. Cassava, Manihot esculentaand, is one of major crop in Africa, and could be a candidate of space food materials. Since resource is limited for space agriculture in many aspects, crop yield should be high in efficiency, and robust as well. The efficiency is measured by farming space and time. Harvest yield of cassava is about 41 MJ/ m2 (70 ton/ha) after 11 months of farming. Among rice, wheat, potato, and sweet potato, cassava is ranked to the first place (40 m2 ) in terms of farming area required to supply energy of 5 MJ/day, which is recommended for one person. Production of cassava could be made under poor condition, such as acidic soil, shortage of fertilizer, draught. Laterite, similar to Martian regolith. Propagation made by stem cutting is an advantage of cassava in space agriculture avoiding entomophilous or anemophilous process to pollinate. Feature of crop storage capability is additional factor that determines the efficiency in the whole process of agriculture. Cassava root tuber can be left in soil until its consumption. Cassava might be an African contribution to space agriculture.

    2008-12-01

    A 14-yr-old male African warthog (Phacochoerus aethiopicus) with a chronic history of intermittent unilateral epistaxis, degenerative osteoarthritis, and intermittent weakness in the distal lumbar trunk was evaluated to determine the source of epistaxis. No obvious cause was determined, and in light of severe osteoarthritis and a holosystolic cardiac murmur, the animal was euthanized. A tumor of the right adrenal gland involving the medulla was found at gross necropsy. Immunohistochemical staining of the tumor was positive for chromogranin and negative for neurofilament protein, which was diagnostic for pheochromocytoma. No lesions were observed in either nasal cavity. Systolic, diastolic, and mean arterial pressures measured at the time of immobilization were elevated when compared with another African warthog immobilized with a similar anesthetic regimen. Additionally, the warthog had pronounced serum norepinephrine dominance with a norepinephrine:epinephrine ratio of 10.0, compared with 0.36 from clinically normal warthogs. Practitioners should consider pheochromocytoma when evaluating warthogs or swine for epistaxis. PMID:19110715

    2000-01-01

    Full Text Available Two genetic markers (the mtDNA COI-COII intergenic region and the microsatellite A7 with high levels of variability in South African and European honey bees were analyzed in wild swarms of Africanized honey bees (Apis mellifera from Costa Rica. Allelic or haplotypic frequencies revealed high levels of genetic variability at these loci in this population. Most of the alleles were African alleles, although some European-derived alleles were also present. Differences in the frequencies of African alleles between African and Africanized samples were minor, which could be explained by founder effects occurring during the introduction of African honey bee populations into South America.

  5. 50 Years of Independence: Reflections on the Role of Publishing and Progressive African Intellectuals

    Walter Bgoya

    2014-01-01

    Full Text Available In this contribution, the role of progressive African intellectuals fifty years after independence in the context of African postcolonial, political and socio-economic conditions is examined. African intellectuals have been marginalized by the African state, and progressive intellectuals have been disunited in their struggle for relevance. The possibilities for African intellectual autonomy and international solidarity are shown through a recollection of the flourishing intellectual environment and local publishing output of post-independence Tanzania. The end of that era and the demise of publishing, including in African languages, has negatively impacted African economic and intellectual emancipation and can only be addressed by international solidarity among progressive intellectuals.

    Introduced exotic plants can drive ecosystem change. We studied invasion and establishment ofBrassica tournefortii (African mustard), a noxious weed, in the Chemehuevi Valley, western Sonoran Desert, California. We used long-term data sets of photographs, transects for biomass of annual plants, and densities of African mustard collected at irregular intervals between 1979 and 2009. We suggest that African mustard may have been present in low numbers along the main route of travel, a highway, in the late 1970s; invaded the valley along a major axial valley ephemeral stream channel and the highway; and by 2009, colonized 22 km into the eastern part of the valley. We developed predictive models for invasibility and establishment of African mustard. Both during the initial invasion and after establishment, significant predictor variables of African mustard densities were surficial geology, proximity to the highway and axial valley ephemeral stream channel, and number of small ephemeral stream channels. The axial valley ephemeral stream channel was the most vulnerable of the variables to invasions. Overall, African mustard rapidly colonized and quickly became established in naturally disturbed areas, such as stream channels, where geological surfaces were young and soils were weakly developed. Older geological surfaces (e.g., desert pavements with soils 140,000 to 300,000 years old) were less vulnerable. Microhabitats also influenced densities of African mustard, with densities higher under shrubs than in the interspaces. As African mustard became established, the proportional biomass of native winter annual plants declined. Early control is important because African mustard can colonize and become well established across a valley in 20 yr.

    2014-12-01

    Active surveillance (AS) is a treatment strategy for prostate cancer (PCa) whereby patients diagnosed with PCa undergo ongoing characterization of their disease with the intent of avoiding radical treatment. Previously, AS has been demonstrated to be a reasonable option for men with low-risk PCa, but existing cohorts largely consist of Caucasian Americans. Because African Americans have a greater incidence, more aggressive, and potentially more lethal PCa than Caucasian Americans, it is unclear if AS is appropriate for African Americans. We performed a review of the available literature on AS with a focus on African Americans.

    Full Text Available This article passes from Christianity to African Religion and back again, in order to gain new insight on reconciliation. Traditional Christian reconciliation models are valuable but also contextual and limited; thus new models should be sought. African myths of community, acceptance and rebellion offer alternative ways of understanding reconciliation. When evaluated according to the principles of integration and transcendence, these myths meet the criteria of better religion and emphasise Christian notions that are often ignored in tradition Christianity. These new African-inspired insights can be used in Christian liturgy as a number of examples prove.

    This study argues for the integration of African oral traditions and other elements of traditional learning into the modern school curriculum. It thus contributes to supporting the increased relevance of education to local communities. In particular, using the example of riddles collected from one of the main ethnic groups in Northwestern Tanzania, the Haya people, the present study challenges the views of those social and cultural anthropologists who hold that African riddles have no substantially meaningful educational value. Instead, it is maintained that riddles make an important contribution to children's full participation in the social, cultural, political, and economic life of African communities, especially by fostering critical thinking and transmitting indigenous knowledge.

  14. Disability and masculinity in South African autosomatography

    Directory of Open Access Journals (Sweden)

    Ken J. Lipenga

    2014-04-01

    Full Text Available This article examines the representation of disability by disabled black South African men as portrayed in two texts from the autosomatography genre, which encompasses first-person narratives of illness and disability. Drawing on extracts from Musa E. Zulu’s The language of me and William Zulu’s Spring will come, the article argues that physical disability affects heteronormative concepts of masculinity by altering the body, which is the primary referent for the construction and performance of hegemonic masculinity. In ableist contexts, the male disabled body may be accorded labels of asexuality. This article therefore reveals how male characters with disabilities reconstruct the male self by both reintegrating themselves within the dominant grid of masculinity and reformulating some of the tenets of hegemonic masculinity.

    The first African School of Physics (ASP2010), a new physics school that will combine scientific learning and technology transfer, is to be organized in South Africa with the support of various institutes and laboratories from Europe and the US. Christine Darve, the head organizer and an accelerator engineer from Fermilab currently working in CERN's Technology Department, provides some insight into the programme's mission.   Christine Darve was previously the secretary of a ‘Physics Without Borders’ meeting in Sarajevo, an experience that fuelled her passion to help the less fortunate to benefit from developments in science. After meeting Steve Muanza, a physicist of Congolese descent who visited Fermilab in 2004, she initiated steps to organize a physics school that would bring scientific learning and technology transfer from European and American institutes to Africa. A physicist at IN2P3, the Centre de Physique des Particules in Marseilles, Muanza is the director of this fi...

  16. African Botanical Heritage for New Crop Development

    Directory of Open Access Journals (Sweden)

    P. Van Damme

    2008-01-01

    Full Text Available The African continent is rather poor in plant biodiversity when compared to other continents on and around the equator. Nevertheless, lots of useful plant species have been domesticated from Sub-Sahara Africa material. Ethnobotanical research offers the possibility to collect information on the use and utility of wild plant species from traditional peoples often living in or close to a challenging natural environment. This type of information then allows us to find new candidates for domestication and subsequent crop development for income generation and increased food security. The case of Gnetum africanum illustrates the practical implications of developing a lesserknown species, and highlights the institutional problems that go together with niche crop development. The latter are subsequently presented and discussed in extenso, and solutions proposed in a second part of this review text.

    Directory of Open Access Journals (Sweden)

    Abolaji Joachim Abiodun

    2014-09-01

    Full Text Available The modern workplace is composed of people with diverse backgrounds in terms of nationality, culture, religion, age, education and socioeconomic status. Each of these people enters the work with different values, goals, and perceptions of acceptable behaviours. The diverse background creates ethical challenges for individuals as well as managers. There are issues and decisions that are to be made by workers in the organization that have implications for their job security and salary, and success of the organization. Pressure may be on the workers to protect their own interests, sometimes at the risk of losing personal and corporate integrity. This paper attempts to evaluate ethical dilemmas and conflicts from an Africa perspective, bearing in mind different value systems between western and African nations.

  18. What Accounts for Growth in African Agriculture

    Directory of Open Access Journals (Sweden)

    Guy B. Nkamleu

    2008-01-01

    Full Text Available Empirical relationships between the rates of growth and total factor productivity growth, physical input accumulation, as well as institutional and agro-ecological change is evaluated using an international panel data set on 26 African countries and covering the period 1970-2000. The analysis employs the broader framework provided by empirical growth literature and recent developments in TFP measurement. Results suggest a positive evolution of the total factor productivity during the studied period. This positive performance of the productivity of the agricultural sector was due to positive technological progress rather than technology absorption. However, growth accounting computation highlights the fact that factor accumulation accounts for a large share of agricultural output growth and fertilizer has been the most statistically important physical input contributor to agricultural growth. The study also highlights the extent to which agricultural growth contributors vary across countries and regions in relation with different country conditions, institutions and politico-historical factors.

    Full Text Available This research article explores the concept that libraries as communication centres in sub-Saharan Africa can play a vital role in bringing poverty relief by providing greater access to information through modern technology. It discusses the patrons who can benefit from community information centres and explores their particular needs. I have researched how modern tools like the Internet, computers, e-readers and cell phones can bring valuable information to impoverished citizens. My research was conducted through reading research papers using article databases, books and Internet websites. The future for libraries in sub-Saharan Africa is bright, as new technology opens up vast opportunities to share information in a way that is accessible, affordable and adaptable to the needs of the African people. I recommend that librarians and relief organisations in Southern Africa seriously consider using modern technology to provide information that will empower its citizens.

  20. Getting African climate change research recognised

    Energy Technology Data Exchange (ETDEWEB)

    Denton, Fatima; Anderson, Simon; Ayers, Jessica

    2011-11-15

    Across Africa, programmes such as the Climate Change Adaptation in Africa initiative are investigating what it means for countries and communities to effectively adapt to climate change, and how this can be achieved in practice. But research results are not always recognised by policymakers or the global research community — in part because they are not visible within the traditional hallmark of scientific scholarship and credibility, peer-reviewed literature. Greater efforts are required to encourage African scientists to engage in the peer-review process and give their research the credibility it needs to convince decision makers that robust scientific findings support the solutions offered. At the same time, decision makers themselves must find ways of assessing and making use of robust research outside the peer-review arena.

  2. The African landscape through space and time

    Paul, Jonathan D.; Roberts, Gareth G.; White, Nicky

    2014-06-01

    It is generally accepted that Cenozoic epeirogeny of the African continent is moderated by convective circulation of the mantle. Nevertheless, the spatial and temporal evolution of Africa's "basin-and-swell" physiography is not well known. Here we show how continental drainage networks can be used to place broad constraints on the pattern of uplift through space and time. First, we assemble an inventory of 710 longitudinal river profiles that includes major tributaries of the 10 largest catchments. River profiles have been jointly inverted to determine the pattern of uplift rate as a function of space and time. Our inverse model assumes that shapes of river profiles are controlled by uplift rate history and modulated by erosional processes, which can be calibrated using independent geologic evidence (e.g., marine terraces, volcanism and thermochronologic data). Our results suggest that modern African topography started to develop ˜30 Myr ago when volcanic swells appeared in North and East Africa. During the last 15-20 Myr, subequatorial Africa was rapidly elevated, culminating in the appearance of three large swells that straddle southern and western coasts. Our results enable patterns of sedimentary flux at major deltas to be predicted and tested. We suggest that the evolution of drainage networks is dominated by rapid upstream advection of signals produced by a changing pattern of regional uplift. An important corollary is that, with careful independent calibration, these networks might act as useful tape recorders of otherwise inaccessible mantle processes. Finally, we note that there are substantial discrepancies between our results and published dynamic topographic predictions.

  3. Astronomy for teachers: A South African Perspective

    Science.gov (United States)

    de Witt, Aletha; West, Marion; Leeuw, Lerothodi; Gouws, Eldrie

    2015-08-01

    South Africa has nominated Astronomy as a “flagship science” and aims to be an international Astronomy hub through projects such as the Square Kilometre Array (SKA) and the South African Large Telescope (SALT). These projects open up career opportunities in maths, science and engineering and therefore offers a very real door for learners to enter into careers in science and technology through Astronomy. However, the Trends in International Mathematics and Science Survey (TIMSS), the Global Competitiveness Report (GCR) and Annual National Assessment (ANA) have highlighted that South Africa’s Science and Mathematics education is in a critical condition and that South African learners score amongst the worst in the world in both these subjects. In South Africa Astronomy is generally regarded as the worst taught and most avoided Natural Science knowledge strand, and most teachers that specialised in Natural Sciences, never covered Astronomy in their training.In order to address these issues a collaborative project between the University of South Africa (UNISA) and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) was initiated, which aims to assist teachers to gain more knowledge and skills so that they can teach Astronomy with confidence. By collaborating we aim to ensure that the level of astronomy development will be raised in both South Africa and the rest of Africa.With the focus on Teaching and Learning, the research was conducted within a quantitative paradigm and 600 structured questionnaires were administered to Natural Science teachers in Public primary schools in Gauteng, South Africa. This paper reports the findings of this research and makes recommendations on how to assist teachers to teach Astronomy with confidence.

    The prevalence of food allergy is increasing worldwide and is an important cause of anaphylaxis. There are no local South African food allergy guidelines. This document was devised by the Allergy Society of South Africa (ALLSA), the South African Gastroenterology Society (SAGES) and the Association for Dietetics in South Africa (ADSA). Subjects may have reactions to more than one food, and different types and severity of reactions to different foods may coexist in one individual. A detailed history directed at identifying the type and severity of possible reactions is essential for every food allergen under consideration. Skin-prick tests and specific immunoglobulin E (IgE) (ImmunoCAP) tests prove IgE sensitisation rather than clinical reactivity. The magnitude of sensitisation combined with the history may be sufficient to ascribe causality, but where this is not possible an incremental oral food challenge may be required to assess tolerance or clinical allergy. For milder non-IgE-mediated conditions a diagnostic elimination diet may be followed with food re-introduction at home to assess causality. The primary therapy for food allergy is strict avoidance of the offending food/s, taking into account nutritional status and provision of alternative sources of nutrients. Acute management of severe reactions requires prompt intramuscular administration of adrenaline 0.01 mg/kg and basic resuscitation. Adjunctive therapy includes antihistamines, bronchodilators and corticosteroids. Subjects with food allergy require risk assessment and those at increased risk for future severe reactions require the implementation of risk-reduction strategies, including education of the patient, families and all caregivers (including teachers), the provision of a written emergency action plan, a MedicAlert necklace or bracelet and injectable adrenaline (preferably via auto-injector) where necessary.

  11. Disaster management and humanitarian logistics – A South African perspective

    Directory of Open Access Journals (Sweden)

    Wilna L. Bean

    2011-11-01

    Full Text Available Disasters are becoming an unavoidable part of everyday life throughout the world, including South Africa. Even though South Africa is not a country affected by large-scale disasters such as earthquakes, the impact of disasters in South Africa is aggravated significantly by the vulnerability of people living in informal settlements. Humanitarian logistics, as a ‘new’ sub-field in the supply chain management context, has developed significantly recently to assist in disaster situations. This paper provides an overview of the South African humanitarian logistics context. Even though humanitarian logistics plays a critical role in the aftermath of disasters, it extends far beyond events that can typically be classified as ‘disasters’. Therefore the implication of the South African humanitarian logistics context on future research and collaboration opportunities in South African humanitarian logistics is also discussed. Finally, two recent case studies in the South African humanitarian logistics environment are discussed.

    Full Text Available A description is provided of work performed as part of the fruit logistics infrastructure project commissioned by the South African Deciduous Fruit Producers’ Trust and coordinated by the South African Council for Scientific and Industrial Research, as described in [Van Dyk FE & Maspero E, 2004, An analysis of the South African fruit logistics infrastructure, ORiON, 20(1, pp. 55–72]. After a brief introduction to the problem, two models (a single-commodity graph theoretic model and a multi-commodity mathematical programming model are derived for determining the maximal weekly flow or throughput of fresh fruit through the South African national export infrastructure. These models are solved for two extreme seasonal export scenarios and the solutions show that no export infrastructure expansion is required in the near future - observed bottlenecks are not fundamental to the infrastructure and its capacities, but are rather due to sub-optimal management and utilisation of the existing infrastructure.

Methods We collected data on the scale using an audio computer assisted self-interview (ACASI) format. We validated the scale with a sample of 62 African American participants living with HIV. Results Findings demonstrated that stigma can be measured succinctly and effectively in a 14-item scale with two subscales measuring enacted and internalized stigma. Discussion We identified many advantages to using the scale, which demonstrated good psychometric properties when used with an audio computer assisted self-interview format and with an African American sample. We recommend this scale’s use in both clinical practice and research study of HIV-stigma reduction interventions with African American populations.

    Very few data exist that describe the risk of injury in African American health care workers, who are highly represented in health care occupations. The present study examined the risk for work-related injury in African American hospital workers. Hospital Occupational Health Service medical records and a hospital human resource database were used to compare risk of injury between African American and white workers after adjusting for gender, age, physical demand of the job, and total hours worked. Risk of work-related injury was 2.3 times higher in African Americans. This difference was not explained by the other independent variables. Differences in injury reporting, intra-job workload, psychosocial factors, and organizational factors are all potential explanations for racial disparity in occupational injury. More research is needed to clarify these findings. PMID:11039167

    Full Text Available Background. This study tested the hypothesis that data from random digit-dial telephone surveys underestimate the prevalence of cigarette smoking among African-American adults. Method. A novel, community-sampling method was used to obtain a statewide, random sample of N= 2118 California (CA African-American/Black adults, surveyed door-to-door. This Black community sample was compared to the Blacks in the CA Health Interview Survey (N = 2315, a statewide, random digit-dial telephone-survey conducted simultaneously. Results. Smoking prevalence was significantly higher among community (33% than among telephone-survey (19% Blacks, even after controlling for sample-differences in demographics.Conclusions. Telephone surveys underestimate smoking among African-Americans and probably underestimate other health risk behaviors as well. Alternative methods are needed to obtain accurate data on African-American health behaviors and on the magnitude of racial disparities in them.

  20. Review of script displays of African languages by current software

    OpenAIRE

    Gee, Quintin

    2005-01-01

    All recorded African languages that have a writing system have orthographies which use the Roman or Arabic scripts, with a few exceptions. Whilst Unicode successfully handles the encoding of both these scripts, current software, in particular web browsers, take little account of users wishing to operate in a minority script. Their use for displaying African languages has been limited by the availability of facilities and the desire to communicate with the ‘world’ through major languages such ...

    OpenAIRE

    Chafer, Tony

    2002-01-01

    Key developments in Franco-African relations since 1994 are reviewed. Reservations are expressed about the widely held view that these relations have undergone a process of normalization in recent years and that France is disengaging from its traditional pre carre (sphere of influence) in Black Africa. Instead, it is argued that, under pressure from a rapidly evolving international environment and a changing domestic policy context, a partial modernization of French African policy has taken p...

    2013-02-01

    Full Text Available Envenoming syndrome from Africanized bee stings is a toxic syndrome caused by the inoculation of large amounts of venom from multiple bee stings, generally more than five hundred. The incidence of severe toxicity from Africanized bee stings is rare but deadly. This report reveals that because of the small volume of distribution, having fewer stings does not exempt a patient from experiencing an unfavorable outcome, particularly in children, elderly people or underweight people.

    This paper locates the chief culprit for the failure of structural adjustment in Africa at the conceptual level rather than the weak implementation capacity of African governments. The neo-classical economic microfoundations, associated intermediate propositions and theories underlying adjustment seriously mis-specify the nature of African economies. Policies are often in conflict due to the inconsistencies within the adjustment model. Despite its name the model excludes vital structural feat...

  1. Solving the Traveling Salesman's Problem Using the African Buffalo Optimization.

    Science.gov (United States)

    Odili, Julius Beneoluchi; Mohmad Kahar, Mohd Nizam

    2016-01-01

    This paper proposes the African Buffalo Optimization (ABO) which is a new metaheuristic algorithm that is derived from careful observation of the African buffalos, a species of wild cows, in the African forests and savannahs. This animal displays uncommon intelligence, strategic organizational skills, and exceptional navigational ingenuity in its traversal of the African landscape in search for food. The African Buffalo Optimization builds a mathematical model from the behavior of this animal and uses the model to solve 33 benchmark symmetric Traveling Salesman's Problem and six difficult asymmetric instances from the TSPLIB. This study shows that buffalos are able to ensure excellent exploration and exploitation of the search space through regular communication, cooperation, and good memory of its previous personal exploits as well as tapping from the herd's collective exploits. The results obtained by using the ABO to solve these TSP cases were benchmarked against the results obtained by using other popular algorithms. The results obtained using the African Buffalo Optimization algorithm are very competitive. PMID:26880872

    Full Text Available In this study, data on web links collected from 15 African countries, three with the highest Internet penetration in each of North, West, Central, East, and South regions were used to study the number and origins of links to Africa. The sample has a ratio of one Internet user per 12 persons. Altogether, all African countries generated a total of 124,047,702 Web pages and 30,546,967 inlinks to the pages, an average of about 0.25 links per page. But the sample constituted which 28% of all the countries in the region generated 98,629,700 pages and 21,272,500 inlinks, an average of about 0.21 inlinks per page. South Africa ranked highest in web pages and web links per population and also received the highest number of inlinks from other African countries and the G8. However, Kenya linked other African countries more than the others did. Population size does not relate to number of web pages, self-inlinks, and inlinks or penetration, but relates positively with number of Internet users. Among others, a major step in boosting use of Internet resources in Africa will be in developing policies that will encourage African countries to use information developed by other African countries.

  3. A critical analysis on African Traditional Religion and the Trinity

    2013-01-01

    Full Text Available To what extent do the resources of African Traditional Religion (ATR contribute towards Christian theological discourse and benefit the African church? ATR is accommodated in the African Initiated Churches (AICs. The members of these churches aim to be Christian without losing their African identity. ATR is a religion that was practised throughout Africa before the arrival of the Western missionaries. The core premise of ATR is the maintenance of African culture and its main feature is loyalty to the ancestors and the accompanying rituals that express this loyalty. This study addresses the appropriateness of ATR’s resources in terms of their contribution to the doctrine of the Trinity. When the early church worshipped God the Father and God the Son (Jesus in the presence of the Holy Spirit, a tension developed. The questions of monotheism versus polytheism and the nature and position of Jesus within the Trinity were put forward and addressed. The doctrine of the Trinity is uniquely Christian and includes the belief in Jesus Christ as the Son of God who alone mediates between God and men. There is, on the other hand, an understanding that Africans worship one Supreme Being and venerate ancestors as intermediaries to the one Supreme Being, without clear roles being ascribed to Jesus Christ and the Holy Spirit. This article enquires whether the process of Africanisation and contextualisation consciously or unconsciously downgraded Jesus Christ as Mediator who came to reveal who God is and to reconcile humankind to him.

    2015-09-01

    Advances have occurred in breast cancer survivorship but, for many African-American women, challenges and gaps in relevant information remain. This article identifies opportunities to address disparities in breast cancer survival and quality of life, and thereby to increase breast cancer survivorship among African-American women. For breast cancer survivors, common side effects, lasting for long periods after cancer treatment, include fatigue, loss of strength, difficulty sleeping, and sexual dysfunction. For addressing physical and mental health concerns, a variety of interventions have been evaluated, including exercise and weight training, dietary interventions, yoga and mindfulness-based stress reduction, and support groups or group therapy. Obesity has been associated with breast cancer recurrence and poorer survival. Relative to white survivors, African-American breast cancer survivors are more likely to be obese and less likely to engage in physical activity, although exercise improves overall quality of life and cancer-related fatigue. Considerable information exists about the effectiveness of such interventions for alleviating distress and improving quality of life among breast cancer survivors, but few studies have focused specifically on African-American women with a breast cancer diagnosis. Studies have identified a number of personal factors that are associated with resilience, increased quality of life, and positive adaptation to a breast cancer diagnosis. There is a need for a better understanding of breast cancer survivorship among African-American women. Additional evaluations of interventions for improving the quality of life and survival of African-American breast cancer survivors are desirable. PMID:26303657

    2013-01-01

    A meningococcal serogroup A polysaccharide/tetanus toxoid conjugate vaccine (PsA-TT) (MenAfriVac#x2122;) is being deployed in countries of the African meningitis belt. Experience with other polysaccharide/protein conjugate vaccines has shown that an important part of their success has been their ability to prevent the acquisition of pharyngeal carriage and hence to stop transmission and induce herd immunity. If PsA-TT is to achieve the goal of preventing epidemics, it must be able to prevent the acquisition of pharyngeal carriage as well as invasive meningococcal disease and whether PsA-TT can prevent pharyngeal carriage needs to be determined. To address this issue, a consortium (the African Meningococcal Carriage (MenAfriCar) consortium) was established in 2009 to investigate the pattern of meningococcal carriage in countries of the African meningitis belt prior to and after the introduction of PsA-TT. This article describes how the consortium was established, its objectives and the standardised field and laboratory methods that were used to achieve these objectives. The experience of the MenAfriCar consortium will help in planning future studies on the epidemiology of meningococcal carriage in countries of the African meningitis belt and elsewhere.

    ENGLISH ABSTRACT: The production of scientific publications in engineering in South Africa has expanded over the last three decades. Because engineering is an important science, this expansion has implications for the growth and development of the economy. Drawing on a sample range of years of the publications stored in the ISI Web of Knowledge, the engineering publications of South Africans for a 30-year period from 1975-2005 are analysed. This analysis shows that the production of scientific publications in engineering by South African researchers has increased during the analysed period; that the number of researchers per publication has grown; that the number of countries collaborating with South Africa has increased; and that the number of sole-authored papers has decreased. Domestic collaboration (between researchers within South Africa has decreased, while international collaboration has grown considerably. The key objective of the paper is to find out whether the production of publications is related to the level of collaboration, and to see how collaboration can be regressed from other known variables. It is clear from the study that collaboration is a decisive factor in the production of scientific publications in engineering in South Africa.

  8. Interactions between Oceanic Saharan Air Layer and African Easterly Jet- African Easterly Waves System

    Hosseinpour, F.; Wilcox, E. M.

    2013-12-01

    Aerosols have robust influences on multi-scale climatic systems and variability. Non-linear aerosol-cloud-climate interactions depend on many parameters such as aerosol features, regional atmospheric dynamics and variability. Although there are remarkable modeling studies indicating that aerosols induce robust modifications in cloud properties, circulations and the hydrological cycle, many of the physical and dynamical processes involving in these complex interactions between aerosols and Earth's system are still poorly understood. Better understanding the contribution of aerosols with atmospheric phenomena and their transient changes are crucial for efforts to evaluate climate predictions by next generation climate models. This study provides strong evidence of mechanistic relationships between perturbations of the oceanic Saharan air layer (OSAL) and anomalies of atmospheric circulations over the eastern tropical Atlantic/Africa. These relationships are characterized using an ensemble of daily datasets including the Modern-Era Retrospective Analysis for Research and Applications (MERRA), the Moderate Resolution Imaging Spectro-radiometer (MODIS), and the Sea-viewing Wide Field-of-View Sensor (SeaWIFS) for the boreal summer season. The study is motivated by previous results suggesting that oceanic dust-induced large-scale to meso-scale climatic adjustments. Our hypothesis is that perturbations in OSAL significantly interact with regional climate variability through African Easterly Jet- African Easterly Waves (AEJ-AEW) system. Passive/ active phases of AEWs in the northern and southern-track wave packets are associated with dipole patterns of thermal/dynamical anomalies correlated with perturbations of aerosol optical depth (AOD) in OSAL. Enhanced (suppressed) dust AOD in OSAL are significantly correlated with convective re-circulation within subsidence region of Hadley cell as well as robust mid-level dipole vorticity disturbances downstream of the AEJ core

  9. Supplement to South African national bibliography on radioanalytical chemistry: South African authors only. 1975-1982

    International Nuclear Information System (INIS)

    The South African National Bibliography on Radioanalytical Chemistry was initiated by Dr Max Peisach of the National Accelerator Centre, Faure (formerly SUNI) and is intended to cover books, papers and reports published by South African scientists while affiliated to South African institutes, even if the work was carried out at foreign laboratories. The first edition (SUNI 56) covered material published to the end of 1977. The present edition is a supplement to the former and covers the period 1975 to 1982. The papers are divided into two categories. The first consists of papers on activation analysis, whether delayed or prompt and deals with the following: charged particle activation analysis, neutron activation analysis, photon activation and x-ray (including particle-induced x-ray emission, PIXE), prompt analysis and scattering, but is restricted to nuclear particle scattering. The second category deals with radioanalytical methods. To restrict the subject matter to those papers which stress the analytical approach and use nuclear techniques, this category has been sub-divided into the following subjects: absolute standardisation; computer techniques directly concerned with analysis; counting techniques for measuring radionuclides, nuclear particles or emissions; environmental monitoring related to the measurement of radioactive substances; instrumentation and techniques related to nuclear analytical methodology; isotope dilution analysis; low activity measurements; natural radioactivity counting; radiography; radiotracer methods excluding the routine diagnostic use of radionuclides in medicine and separation techniques. Titles are arranged in order of the year of publication, and with each year in alphabetical order of the surname of the first (and thereafter the next) author

  10. Towards a holistic review of Pan-Africanism: linking the idea and the movement.

    Science.gov (United States)

    Young, Kurt B

    2010-01-01

    This article explores two general approaches to defining Pan-Africanism. Traditional Pan-Africanism reflects definitions of Pan-Africanism that begin with the assumption that distinctions must be made between early "ideas" of group identification with Africa versus modern organizational activities. However, holistic approaches emphasize the interconnectivity of Pan-African ideas and concrete activities. This discussion explores these approaches and their implications for contemporary analyses of Pan-Africanism. The essay concludes that the holistic line is best suited for developing a new model in Pan-Africanism. PMID:20648996

    1991-01-01

    The energy cost of walking (Cw) and running (Cr), and the maximal O2 consumption (VO2max) were determined in a field study on 17 Pygmies (age 24 years, SD 6; height 160 cm, SD 5; body mass 57.2 kg, SD 4.8) living in the region of Bipindi, Cameroon. The Cw varied from 112 ml.kg-1.km-1, SD 25 [velocity (v), 4 km.h-1] to 143 ml.kg-1.km-1, SD 16 (v, 7 km.h-1). Optimal walking v was 5 km.h-1. The Cr was 156 ml.kg-1.km-1, SD 14 (v, 10 km.h-1) and was constant in the 8-11 km.h-1 speed range. The VO2max was 33.7 ml.kg-1.min-1, i.e. lower than in other African populations of the same age. The Cr and Cw were lower than in taller Caucasian endurance runners. These findings, which challenge the theory of physical similarity as applied to animal locomotion, may depend either on the mechanics of locomotion which in Pygmies may be different from that observed in Caucasians, or on a greater mechanical efficiency in Pygmies than in Caucasians. The low Cr values observed enable Pygmies to reach higher running speeds than would be expected on the basis of their VO2max.

  13. Exploration and mating range in African Pygmies.

    Science.gov (United States)

    Cavalli-Sforza, L L; Hewlett, B

    1982-07-01

    The distributions of exploration range and of mating range were studied among Aka Pygmies of the Central African Republic. Exploration range is defined and methods of estimation for single individuals suggested. A simple exponential distribution is found for individual Aka Pygmies, with variation of exploration range (the parameter defining mobility) with sex, age and ethnic affiliation. Distribution of distances from birthplace and place of residence are compared and show modest differences. The frequency of visits to a given place has also been studied. The average distance between birthplaces of mates is very similar to the mean exploration range. Correlations between individual exploration and mating ranges suggest that it is the male who may be choosing a marriage partner among Pygmies. A theory by Boyce, Küchemann & Harrison (1967) on the relations between "neighbourhood knowledge" and mating distance is inapplicable because of its reliance on the Pareto distribution, which does not apply in the present case, and of other unnecessary assumptions, but the general principle of a close relationship between exploratory activity and mating distance seems valid, at least in the present case. Suggestions are made for causes for the difference between the present distributions and those with other shapes observed in less primitive economies.

    Full Text Available Obesity prevalence in United States (US adults exceeds 30% with highest prevalence being among blacks. Obesity is known to have significant effects on respiratory function and obese patients commonly report respiratory complaints requiring pulmonary function tests (PFTs. However, there is no large study showing the relationship between body mass index (BMI and PFTs in healthy African Americans (AA.To determine the effect of BMI on PFTs in AA patients who did not have evidence of underlying diseases of the respiratory system.We reviewed PFTs of 339 individuals sent for lung function testing who had normal spirometry and lung diffusion capacity for carbon monoxide (DLCO with wide range of BMI.Functional residual capacity (FRC and expiratory reserve volume (ERV decreased exponentially with increasing BMI, such that morbid obesity resulted in patients breathing near their residual volume (RV. However, the effects on the extremes of lung volumes, at total lung capacity (TLC and residual volume (RV were modest. There was a significant linear inverse relationship between BMI and DLCO, but the group means values remained within the normal ranges even for morbidly obese patients.We showed that BMI has significant effects on lung function in AA adults and the greatest effects were on FRC and ERV, which occurred at BMI values < 30 kg/m2. These physiological effects of weight gain should be considered when interpreting PFTs and their effects on respiratory symptoms even in the absence of disease and may also exaggerate existing lung diseases.

    Guided by Leventhal's common sense model of illness representations, this study examined the relationship between hypertension beliefs and self-care behaviors necessary for blood pressure (BP) control in a sample of 111 community-dwelling African Americans with hypertension. Participants completed the revised Illness Perception Questionnaire, BP Self-Care Scale, and a demographic data sheet, and had BP measured. Analyses revealed that beliefs about the causes of hypertension differed by gender and educational level. Stress-related causal attributions accounted for 34.7% of the variance in hypertension beliefs. Participants who believed stress or external factors caused hypertension were less likely to engage in healthy self-care behaviors (e.g., keeping doctor visits, eating low-salt, low-fat diets). Results suggest that patients who are nonadherent with hypertension self-care recommendations may hold hypertension beliefs that are not consistent with the medically endorsed views of this disease. To more effectively treat and control BP, providers should assess patients' hypertension beliefs.

  18. Drug interactions in African herbal remedies.

    2011-01-01

    Herbal usage remains popular as an alternative or complementary form of treatment, especially in Africa. However, the misconception that herbal remedies are safe due to their "natural" origins jeopardizes human safety, as many different interactions can occur with concomitant use with other pharmaceuticals on top of potential inherent toxicity. Cytochrome P450 enzymes are highly polymorphic, and pose a problem for pharmaceutical drug tailoring to meet an individual's specific metabolic activity. The influence of herbal remedies further complicates this. The plants included in this review have been mainly researched for determining their effect on cytochrome P450 enzymes and P-glycoprotein drug transporters. Usage of herbal remedies, such as Hypoxis hemerocallidea, Sutherlandia frutescens and Harpagophytum procumbensis popular in Africa. The literature suggests that there is a potential for drug-herb interactions, which could occur through alterations in metabolism and transportation of drugs. Research has primarily been conducted in vitro, whereas in vivo data are lacking. Research concerning the effect of African herbals on drug metabolism should also be approached, as specific plants are especially popular in conjunction with certain treatments. Although these interactions can be beneficial, the harm they pose is just as great. PMID:21756221

  19. Immunophenotypic lymphocyte profiles in human african trypanosomiasis.

    Full Text Available Human African trypanosomiasis (HAT is a deadly vector-born disease caused by an extracellular parasite, the trypanosome. Little is known about the cellular immune responses elicited by this parasite in humans. We used multiparameter flow cytometry to characterize leukocyte immunophenotypes in the blood and cerebrospinal fluid (CSF of 33 HAT patients and 27 healthy controls identified during a screening campaign in Angola and Gabon. We evaluated the subsets and activation markers of B and T lymphocytes. Patients had a higher percentage of CD19+ B lymphocytes and activated B lymphocytes in the blood than did controls, but lacked activated CD4+ T lymphocytes (CD25+. Patients displayed no increase in the percentage of activated CD8+ T cells (HLA-DR+, CD69+ or CD25+, but memory CD8 T-cell levels (CD8+CD45RA2 were significantly lower in patients than in controls, as were effector CD8 T-cell levels (CD8+CD45RA+CD62L2. No relationship was found between these blood immunophenotypes and disease severity (stage 1 vs 2. However, CD19+ B-cell levels in the CSF increased with disease severity. The patterns of T and B cell activation in HAT patients suggest that immunomodulatory mechanisms may operate during infection. Determinations of CD19+ B-cell levels in the CSF could improve disease staging.

    The relationship between common medicinal plants and major health problems in Africa, specifically Mozambique, is presented here. Emphasis is given to plant species largely used to solve or slow down diarrhoea, malaria, respiratory, and sexual complaints. These diseases, together with malnutrition/ anaemia, mental diseases, and rheumatism/arthritis are the main concern of healthcare countrywide. Diarrhoea is divided into common diarrhoea, bloody-diarrhoea, and cholera; plant species are normally used to slow down diarrhoea recurrence. Tannin is the main chemical compound with both anti-diarrhoeal and antiseptic properties. Traditional medicine seems to be rather helpful in alleviating malaria symptoms such as fever, vomiting, and diarrhoea. Special reference is made to Momordica balsamina, which is highly used to cure vomiting apparently associated with bilis and fever. Rauvolfia caffra contains reserpine, a compound used as anti-hypertension agent. This species is also used as an anti-malarial agent. Traditional medicine seems to have a role in slowing opportunistic infections related to the AIDS virus such as diarrhoea, pneumonia, and skin infections. Prostate hypertrophy is traditionally medicated using mostly Prunus africana and Hypoxis hemerocallidea, species known to contain phytosterol. Research for bioactive compounds in African plants is still in its infancy.

    Full Text Available

    This paper seeks to reveal the patterns of power, influence and ownership that South African media houses are having over Namibians and Namibian media outlets. The hypothesis is that there has recently been an increased interest in Namibia as a source of further revenue for South African media businesses as well as an opportunity for further strengthening ties of cultural and language issues between the two countries. In addition there might also be increased opportunities for South African political perspectives to be further advanced through linkages with Namibian media outlets.
    The paper further seeks to expand academic discourse to include those countries, such as Namibia, living in South Africa’s cultural and economic shadow, and, in a larger sense, looks at the increasingly regional and even nature of media systems in Africa.
    It tries to move these discussions into everyday discourse, as opposed to the margins, where, as McMillin (2007:68 says:
    we fail to understand the incredible impact of colonialism on the development of their media systems, the regional influence of these systems, and the unique character they take on as they assert their postcolonial identities and meet the challenges of globilization.
    The research refers to the unique position of Namibia, having been, firstly, a German colony, and, later, a South African ‘administered territory’, and makes reference to the implications this had on the shaping and control over the media environment.
    The findings reveal an increase in South African influence and shareholding over Namibian media companies and content. This parallel has strengthened economic ties with South Africa, and in particular the influence of South African retail chains and their stock levels of Namibian versus South African publications.

    Full Text Available The haematological alterations produced on exposure of the African snakehead, Parachanna africans to the sublethal concentration (0.0, 0.1, 1.0 and 10.0 mg/L of cadmium (Cd2+ for 21 days have been studied. Red blood cell (RBC count, haemoglobin (Hb concentration, haematocrit (Hct, the mean corpuscular haemoglobin (MCH and the mean corpuscular volume (MCV levels were decreased with an increase in exposure concentration, but the level of the mean corpuscular haemoglobin concentration (MCHC was increased. These alterations could be attributed to haemolysis and impairment of haemoglobin synthesis, resulting in a hypochromic microcytic anaemia, induced by exposure to cadmium. Cadmium exposure also caused significant decreases in white blood cell (WBC count. The primary consequence of the observed changes in total and differential leucocyte counts in stressed fish was attributed to suppression of the immune system and increased susceptibility to disease. Plasma glucose and total plasma protein concentrations were significantly decreased; showing that cadmium affects the fish energy metabolism. The present study thus confirmed that haematological parameters are very sensitive indicators of fish organism response to chemicals in this case cadmium.

    We present aerosol and trace-gas retrievals from the new Central-African measurement site of Bujumbura, where a new MAX-DOAS instrument and cimel sun photometer have been operational since late 2013. This is the first time that MAX-DOAS measurements are performed in Central Africa, which are critical to resolve the large uncertainties of satellite observations of trace gases and aerosols over this area. The Bujumbura region is a source of strong biogenic compounds and biomass burning products, and invaluable to study the export of African emissions to the Indian ocean. Using the bePRO radiative transfer tool, we retrieve aerosol optical depths (AODs) and vertical extinction profiles for aerosols and trace gases such as NO2 and HCHO. The AOD retrievals are compared to the co-located AERONET sun photometer measurements and further analysed to investigate seasonal and diurnal cycles in the observed variability or to detect biomass-burning events.For the trace gases NO2 and HCHO, the ground-based MAX-DOAS vertical columns and profiles are used for tropospheric trace-gas validation of the GOME-2 and OMI satellites. We further discuss the representativity of the site regarding satelitte comparisons and modelling efforts, given its specific orography.

    East Africa is a strategic region to study human genetic diversity due to the presence of ethnically, linguistically, and geographically diverse populations. Here, we provide new insight into the genetic history of populations living in the Sudanese region of East Africa by analysing nine ethnic groups belonging to three African linguistic families: Niger-Kordofanian, Nilo-Saharan and Afro-Asiatic. A total of 500 individuals were genotyped for 200,000 single-nucleotide polymorphisms. Principal component analysis, clustering analysis using ADMIXTURE, FST statistics, and the three-population test were used to investigate the underlying genetic structure and ancestry of the different ethno-linguistic groups. Our analyses revealed a genetic component for Sudanese Nilo-Saharan speaking groups (Darfurians and part of Nuba populations) related to Nilotes of South Sudan, but not to other Sudanese populations or other sub-Saharan populations. Populations inhabiting the North of the region showed close genetic affinities with North Africa, with a component that could be remnant of North Africans before the migrations of Arabs from Arabia. In addition, we found very low genetic distances between populations in genes important for anti-malarial and anti-bacterial host defence, suggesting similar selective pressures on these genes and stressing the importance of considering functional pathways to understand the evolutionary history of populations.

  6. Sample views of African post-graduate students regarding English and the African languages as media of education in African schools in South Africa

    Full Text Available Although African post-graduates recognise the importance of African languages in the education of African children in South Africa, most of them are of the opinion that English should not only be taught as a language from grade 1, but should also be preferred as the main language of instruction for African children from the outset of schooling. In the ensuing pilot study which involved 50 post-graduates, 68% expressed this opinion as against the rest who preferred a variety of other options. The study comments on the implications of these findings for the new democratic language in education policy.

    2014-11-01

    Full Text Available This research investigates how eight undergraduate African American women in science, math, and engineering (SME majors accessed cultural capital and informal science learning opportunities from preschool to college. It uses the multiple case study methodological approach and cultural capital as the framework to better understand their opportunities to engage in free-choice science learning. The article demonstrates that African American women have access to cultural capital and informal science learning inside and outside of home and school environments in P-16 settings. In primary and secondary schools, African American girls acquire cultural capital and access to free-choice science learning in the home environment, museums, science fairs, student organizations and clubs. However, in high school African American female teenagers have fewer informal science learning opportunities like those such as those provided in primary school settings. In college, cultural capital is transmitted through informal science learning that consisted of involvement in student organizations, research projects, seminars, and conferences. These experiences contributed to their engagement and persistence in SME fields in K-16 settings. This research adds to cultural capital and informal science learning research by allowing scholars to better understand how African American women have opportunities to learn about the hidden curriculum of science through informal science settings throughout the educational pipeline.

  9. Impact of Globalization on Traditional African Religion and Cultural Conflict

    2010-05-01

    Full Text Available This paper aims to discuss the impact of the paradigm of global culture on African tradition particularly on the role of African traditional women in conflict prevention and resolution. Global culture, a part of globalization, has not only transported the good side of the economic and social development across the globe but has also changed in the culture of host communities. Some changes include the mode of production and the way things are done, whileothers include the symbolic interaction or the appreciation ofhow social facts are to be seen and appreciated. For example, the change from collectivism social structure that characterizes African society to individualism structure that characterizes the market-oriented culture of western society. This change is without doubt that “Globalization is one of the most important and developed theories of the twentieth century” (Ritzer, 2008: 230. However, one aspect that justifies the importance of this development is the culture (termed civilization in other areas that the application of this concept transports from one location to another. This cultural aspect may be economic, marketing oriented, or just a change in rationale behavior of consumption and production. Nevertheless, this change questions the static existence of rapport, the role that traditional culture plays in the life of African communities, and the impact traditional religions still have on the essence of African culture.

  10. African voices on climate change. Policy concerns and potentials

    International Nuclear Information System (INIS)

    This publication is the result of a process of building an understanding and facilitating a dialogue on the issues related to climate change, on the implications that climate change have to Africa, and on the relevance of the United Nations Framework Convention on Climate Change for the continent. Research work was carried out over a year and twelve African countries were directly engaged in this projects, contributing with the work and expertise of their specialists. A whole process of discussions was started aiming not only at identifying questions concerning the countries directly involved but at illustrating the diversity of Africa's economies and societies, and attempting to raise common issues of interest for the whole of the continent. The objective of this publication is to provide a starting point for the discussions to take place during the African Conference on Policy Options and Responses to Climate Change, 5-8 December 1994, in Nairobi. This conference is not only the culmination of 'Climate and Africa' but, most of all, it opens a forum for discussions on climate issues among African policy makers and for building African positions in relation to the Climate Convention. The ideas expressed here are drawn from the material produced in the Climate and Africa Project. Therefore, this publication does not necessarily represent the positions of the Stockholm Environment Institute or the African Center for Technology Studies in relation to Africa and the Climate Convention

    PURPOSE The purpose of this study is to compare the health of primary caregiving African American grandmothers with diabetes with African American women with diabetes who were not primary caregivers. DESIGN Using a comparative, descriptive, cross-sectional design, 34 African American primary caregiving grandmothers were compared with 34 non-caregiving women with diabetes mellitus; women aged 55–75 years were recruited for this study throughout the central Arkansas. METHODS To measure the overall health, data on blood pressure, body mass index measurements, HbA1c levels, total cholesterol, and urine protein and creatinine levels were collected from all the participants. RESULTS Statistically significant differences between the caregivers and non-caregivers groups in systolic pressure (t = −3.42, P = 0.001) and diastolic pressure (t = −3.790, P = 0.000) and urine protein (W = 294.00, P = 0.000) were noted. Additionally, a clinically significant difference in HbA1c was noted between groups. CONCLUSION Differences in systolic and diastolic pressures, urine protein, and clinically significant differences in HbA1c suggest that African American primary caregiving grandmothers with diabetes mellitus may have more difficulty in maintaining their diabetic health than non-caregiving African American women.

    Wu, Man-Li C.; Reale, Oreste; Schubert, Siegfried D.; Suarez, Max J.; Koster, Randy D.; Pegion, Philip J.

    2009-01-01

    This article investigates the African Easterly Jet (AEJ), its structure and the forcings contributing to its maintenance, critically revisiting previous work which attributed the maintenance of the jet to soil moisture gradients over tropical Africa. A state-of-the-art global model in a high-end computer framework is used to produce a 3-member 73-year ensemble run forced by observed SST to represent the Control run. The AEJ as produced by the Control is compared with the representation of the AEJ in the European Center for Medium Range Forecast Reanalyses (ERA-40) and other observational data sets and found very realistic. Five Experiments are then performed, each represented by sets of 3-member 22 year long (1980-2001) ensemble runs. The goal of the Experiments is to investigate the role of meridional soil moisture gradients, different land surface properties and orography. Unlike previous studies, which have suppressed soil moisture gradients within a highly idealized framework (i.e., the so-called bucket model), terrestrial evaporation control is here achieved with a highly sophisticated landsurface treatment and with an extensively tested and complex methodology. The results show that the AEJ is suppressed by a combination of absence of meridional evaporation gradients over Africa and constant vegetation, even if the individual forcings taken separately do not lead to the AEJ disappearance, but only its modification. Moreover, the suppression of orography also leads to a different circulation in which there is no AEJ. This work suggests that it is not just soil moisture gradients, but a unique combination of geographical features present only in northern tropical Africa, which causes and maintains the jet.

    Remis, Melissa J; Hardin, Rebecca

    2009-12-01

    We combined ethnographic investigations with repeated ecological transect surveys in the Dzanga-Sangha Dense Forest Reserve (RDS), Central African Republic, to elucidate consequences of intensifying mixed use of forests. We devised a framework for transvaluation of wildlife species, which means the valuing of species on the basis of their ecological, economic, and symbolic roles in human lives. We measured responses to hunting, tourism, and conservation of two transvalued species in RDS: elephants (Loxodonta cyclotis) and gorillas (Gorilla gorilla). Our methods included collecting data on encounter rates and habitat use on line transects. We recorded cross-cultural variation in ideas about and interactions with these species during participant observation of hunting and tourism encounters and ethnographic interviews with hunters, conservation staff, researchers, and tourists. Ecologically, gorillas used human-modified landscapes successfully, and elephants were more vulnerable than gorillas to hunting. Economically, tourism and encounters with elephants and gorillas generated revenues and other benefits for local participants. Symbolically, transvaluation of species seemed to undergird competing institutions of forest management that could prove unsustainable. Nevertheless, transvaluation may also offer alternatives to existing social hierarchies, thereby integrating local and transnational support for conservation measures. The study of transvaluation requires attention to transnational flows of ideas and resources because they influence transspecies interactions. Cross-disciplinary in nature, transvalution of species addresses the political and economic challenges to conservation because it recognizes the varied human communities that shape the survival of wildlife in a given site. Transvaluation of species could foster more socially inclusive management and monitoring approaches attuned to competing economic demands, specific species behaviors, and human

    2016-04-01

    The phytomedicine Tulbaghia consists of the fresh or dried subterranean organs of various Tulbaghia species. The genus is endemic to Southern Africa and includes about 20 species, of which only T. alliacea and T. capensis are naturally found in the winter rainfall climate area (the Western Cape). The genus forms part of the Alliaceae family and is a geophyte (plants with an underground perennation organ and leaves that die back annually). Their habitat can range from semi-desert to wet and boggy terrain. Wild garlic is most commonly prepared as an infusion or boiled in water and taken orally. Externally, as a medicated bath, wild garlic is used to treat paralysis and rheumatism and to reduce the temperature in a feverish patient. Internally, rhizome or bulb preparations are taken orally to treat fever; as a remedy for colds and influenza, asthma, tuberculosis, and stomach problems; as an antihypertensive; or to expel intestinal worms. It is also used as a prophylactic against winter infections. Rhizome pieces are often placed in castor oil to make eardrops. For fever and high blood pressure, a tea is made from the bulbs or rhizomes and a small cup taken three times daily. The leaves of the plant are used to treat esophageal cancer and may also be eaten as a vegetable. The demand for Tulbaghia in both formal and informal markets has grown exponentially. Sustainable harvesting focuses on only harvesting enough of the plant so that it still has the capacity for self-renewal. However, because both the above-ground and underground parts of Tulbaghia are commonly used in African traditional medicine, destructive harvesting of the whole plant is inevitable, thus necessitating the large-scale organized propagation of these plants.

    Cook, R J; Dickens, B M

    1981-01-01

    This paper provides an overview of the range of current (1981) abortion laws in the African Commonwealth countries, traces the origins of the laws to their colonial predecessors, and discusses legal reform that would positively provide for legal termination of pregnancy. The authors claim that the range of these laws demonstrates an evolution that leads from customary/common law (Lesotho and Swaziland) to basic law (Botswana, The Gambia, Malawi, Mauritius, Nigeria's Northern States and Seychelles) to developed law (Ghana, Kenya, Nigeria's Southern States, Sierra Leone, and Uganda), and, finally, to advanced law (Zambia and Zimbabwe). The authors call for treating abortion as an issue of health and welfare as opposed to one of crime and punishment. Since most of the basic law de jure is treated and administered as developed law de facto, the authors suggest decriminalizing abortion and propose ways in which to reform the law: clarifying existing law; liberalizing existing law to allow abortion based upon certain indications; limiting/removing women's criminal liability for seeking an abortion; allowing hindsight contraception; protecting providers treating women in good faith; publishing recommended fees for services to protect poor women; protecting providers who treat women with incomplete abortion; and punishing providers who fail to provide care to women in need, with the exception of those seeking protection under a conscience clause. The authors also suggest clarifying the means by which health services involving pregnancy termination may be delivered, including: clarification of the qualifications of practitioners who may treat women; specification of the facilities that may treat women, perhaps broken down by gestational duration of the pregnancy; specifying gestational limits during which the procedure can be performed; clarifying approval procedures and consents; and allowing for conscientious objections to performing the procedure.

    African liberation movements and Communist parties often collaborated in their efforts to remove the yoke of colonialism and imperialism from the African continent. This cooperation is not evidence of Communist parties dictating the affairs and decisions of these liberation movements. This inference may be applied to the African National Congress (ANC), Nelson Mandela, and the South African Communist Party (SACP).

    The cratons of Central Africa are formed of various blocks of Archaean and Palaeoproterozoic crust, flanked or truncated by Palaeoproterozoic to Mesoproterozoic orogenic belts. The geology of east Africa has largely been shaped by the events of the Pan-African Orogeny when east and west Gondwana collided to form 'Greater Gondwana' at the end of the Neoproterozoic. The Pan-African orogeny in NE Africa involved the collision of Archaean cratons and the Saharan Metacraton with the Arabian Nubian Shield, a terrane comprising Neoproterozoic juvenile oceanic island arcs. Phanerozoic cover sedimentary rocks, eroded from the Pan-African orogenies, blanket much of NE Africa. Detrital data from these Phanerozoic cover sedimentary rocks, and modern rivers draining both the cover the basement, provide a wealth of information on basement evolution, of particular relevance for regions where the basement itself is poorly exposed due to ancient or modern sedimentary cover. From samples collected in Uganda, Ethiopia, Sudan and Egypt, we provide combined U-Pb and Hf-isotope zircon, U-Pb rutile and Ar-Ar mica datasets, heavy mineral analyses, and bulk trace element data, from Archaean basement, Phanerozoic cover and modern river sediment from the Nile and its tributaries to document the evolution of the North African crust. The data document early crust-forming events in the Congo Craton and Sahara Metacraton, phased development of the Arabian Nubian Shield culminating in the Neoproterozoic assembly of Gondwana during the Pan African Orogeny, and the orogen's subsequent erosion, with deposition of voluminous Phanerozoic cover.

  11. African American Women’s Perceptions and Experiences about Breastfeeding

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available There are health benefits to breastfeeding for both mothers and their children. The preventive health effects of breastfeeding continue into adulthood, lowering rate of various chronic illnesses. African American women, especially of lower socioeconomic status, are less likely to breastfeed in comparison to their racial and ethnic counterparts. The purpose of this study was to explore how African American women experience breastfeeding in the early stages of postpartum care. Two focus groups (N=20, 10 in each group were conducted with African American mothers. Results revealed that participants felt that there were health benefits to breastfeeding, and organizations such as WIC provided support. However, participants stated that lack of information, negative perceptions, and unforeseen circumstances were barriers to breastfeeding. This study proposes support and interventions for this group to increase breastfeeding among this population.

    Given the importance of Africa to studies of human origins and disease susceptibility, detailed characterisation of African genetic diversity is needed. The African Genome Variation Project (AGVP) provides a resource to help design, implement and interpret genomic studies in sub-Saharan Africa (SSA) and worldwide. The AGVP represents dense genotypes from 1,481 and whole genome sequences (WGS) from 320 individuals across SSA. Using this resource, we find novel evidence of complex, regionally distinct hunter-gatherer and Eurasian admixture across SSA. We identify new loci under selection, including for malaria and hypertension. We show that modern imputation panels can identify association signals at highly differentiated loci across populations in SSA. Using WGS, we show further improvement in imputation accuracy supporting efforts for large-scale sequencing of diverse African haplotypes. Finally, we present an efficient genotype array design capturing common genetic variation in Africa, showing for the first time that such designs are feasible. PMID:25470054

  13. A review of phytoplankton dynamics in tropical African lakes

    Directory of Open Access Journals (Sweden)

    Charles F. Musil

    2010-03-01

    Full Text Available This paper provides a synthesis of current knowledge on phytoplankton production, seasonality, and stratification in tropical African lakes and considers the effects of nutrient enrichment and the potential impacts of climate warming on phytoplankton production and composition. Tropical African lakes are especially sensitive to climate warming as they experience wide fluctuations in the thermocline over a narrow range of high water temperatures. Recent climate warming has reduced phytoplankton biomass and production in the lakes. A decline in the production of palatable chlorophytes and an increase in cyanobacteria has led to reduced zooplankton production and a consequent decline in fish stocks, all of which can be associated with the elevated water temperatures. This indicates that even moderate climate warming may destabilise phytoplankton dynamics in tropical African lakes, thereby reducing water quality and food resources for planktivorous fish, with consequent negative impacts on human livelihoods.

    African American faith communities are an important source of social capital. The present study adapted a theory-based social capital instrument to result in religious (e.g., from organized worship) and spiritual (e.g., from relationship with higher power) capital measures. Data from a national sample of 803 African Americans suggest the instruments have high internal reliability and are distinct from general religiosity. Measurement models confirmed factor structures. Religious capital was positively associated with self-rated health status. Religious and spiritual capital were negatively associated with depressive symptoms, but these associations largely became nonsignificant in multivariate models that controlled for demographic characteristics. An exception is for spiritual capital in the form of community participation, which retained a negative association with depressive symptoms. These instruments may have applied value for health promotion research and practice in African American communities.

    Full Text Available Abstract Background Reports of neoplasms in Panthera species are increasing, but they are still an uncommon cause of disease and death in captive wild felids. The presence of two or more primary tumor in large felids is rarely reported, and there are no documented cases of ocular melanoma and mammary mucinous carcinoma in African lions. Case presentation An ocular melanoma and a mammary mucinous carcinoma are described in an African lion (Panthera leo. The first tumour was histologically characterized by the presence of epithelioid and fusiform melanocytes, while the latter was composed of mucus-producing cells with an epithelial phenotype that contained periodic acid-Schiff (PAS and Alcian blue staining mucins. Metastases of both tumor were identified in various organs and indirect immunohistochemistry was used to characterize them. Peribiliary cysts were observed in the liver. Conclusions This is the first description of these tumor in African lions.

    Variation within the gene for the proinflammatory cytokine interleukin (IL)-18 has been associated with inter-individual differences in levels of free protein and disease risk. We investigated the frequency of function-associated IL18 gene haplotypes in an extensive sample (n=2357) of African populations from across the continent. A previously identified five tagging SNP (single-nucleotide polymorphism) haplotype (here designated hGTATA), known to be associated with lower levels of IL-18, was observed at a frequency of 27% in a British population of recent European ancestry, but was found at low frequency (African populations. Potentially protective variants may, as a consequence, be found at low frequency in African individuals and may confer a difference in disease risk.

    2016-10-01

    Despite considerable pain disparities across the care continuum, pain is an understudied health problem in older ethnic minority groups, such as African Americans. Quality pain measurement is a core task in pain management and a mechanism by which pain disparities may be reduced. Pain measurement includes the methods (e.g., assessment approaches, tools) and metrics that researchers and clinicians use to understand the characteristics of pain. However, there are significant issues and gaps that negatively affect pain measurement in older African Americans. Of concern is insufficient representation in pain research, which impedes the testing and refinement of many standardized self-report, behavioral and surrogate report, physiological, and composite measures of pain. The purposes for this article are to discuss the status of pain measurement and factors that affect our knowledge on pain measurement in older African Americans, and to provide guidance for culturally conscientious pain measurement using the available literature.

    Fossil fuel and biofuel emissions of particles in Africa are expected to significantly increase in the near future, particularly due to rapid growth of African cities. In addition to biomass burning emissions prevailing in these areas, air quality degradation is then expected with important consequences on population health and climatic/radiative impact. In our group, we are constructing a new integrated methodology to study the relations between emissions, air quality and their impacts. This approach includes: (1) African combustion emission characterizations; (2) joint experimental determination of aerosol chemistry from ultrafine to coarse fractions and health issues (toxicology and epidemiology). (3) integrated environmental, health and radiative modeling. In this work, we show some results illustrating our first estimates of African anthropogenic emission impacts: - a new African anthropogenic emission inventory adapted to regional specificities on traffic, biofuel and industrial emissions has been constructed for the years 2005 and 2030. Biomass burning inventories were also improved in the frame of AMMA (African Monsoon) program. - carbonaceous aerosol radiative impact in Africa has been modeled with TM5 model and Penner et al. (2011) radiative code for these inventories for 2005 and 2030 and for two scenarios of emissions : a reference scenario, with no further emission controls beyond those achieved in 2003 and a ccc* scenario including planned policies in Kyoto protocol and regulations as applied to African emission specificities. In this study we will show that enhanced heating is expected with the ccc* scenarios emissions in which the OC fraction is relatively lower than in the reference scenario. - results of short term POLCA intensive campaigns in Bamako and Dakar in terms of aerosol chemical characterization linked to specific emissions sources and their inflammatory impacts on the respiratory tract through in vitro studies.

    African trypanosomiasis is a re-emerging disease. We report the case of an African patient whose predominant symptom was infertility due to a granulomatous orchitis. The patient was afebrile and had not been in Africa for years. Lymphadenopathy and splenomegaly led us eventually to the diagnosis of sleeping sickness. After treatment with suramin his spermiogram returned to normal. Sleeping sickness evolves through clinically different stages and leads to death if left untreated. The disease may, however, present clinically extremely variable and may thus be difficult to diagnose. PMID:15936085

  7. The Political Economy of Local Content in African Extractives

    Hansen, Michael W.; Buur, Lars; Therkildsen, Ole;

    Extractive foreign direct investment (FDI) is heralded as the new development opportunity in Africa. But extractive FDI has a record of producing enclaves in host countries with few linkages to the local economy. Only if it creates local content will extractive FDI become a catalyst of development....... This paper analyses the trajectories of local content policies and practices in three African countries – Tanzania, Uganda and Mozambique. We argue that we cannot understand the dynamics and outcomes of local content policies in African extractives without understanding how local content has become ingrained...

  8. Psychiatry in the East African colonies: a background to confinement.

    Science.gov (United States)

    Mahone, S

    2006-08-01

    This article is concerned with the discipline of psychiatry in colonial East Africa as it emerged out of the crime and disorder problem to become an intellectually significant 'East African School' of psychiatry. The process of lunacy certification, in particular, provides a snapshot of the medical and political tensions that existed among the medical establishment, the prison system and the colonial courts, all of whom sought to define collective African behaviour. This historical article utilises archaic terminology, such as 'lunatic' or 'lunacy', as these categories were in use at the time. PMID:16943144

  9. The African Health Profession Regulatory Collaborative for Nurses and Midwives

    2012-08-01

    Full Text Available Abstract Background More than thirty-five sub-Saharan African countries have severe health workforce shortages. Many also struggle with a mismatch between the knowledge and competencies of health professionals and the needs of the populations they serve. Addressing these workforce challenges requires collaboration among health and education stakeholders and reform of health worker regulations. Health professional regulatory bodies, such as nursing and midwifery councils, have the mandate to reform regulations yet often do not have the resources or expertise to do so. In 2011, the United States of America Centers for Disease Control and Prevention began a four-year initiative to increase the collaboration among national stakeholders and help strengthen the capacity of health professional regulatory bodies to reform national regulatory frameworks. The initiative is called the African Health Regulatory Collaborative for Nurses and Midwives. This article describes the African Health Regulatory Collaborative for Nurses and Midwives and discusses its importance in implementing and sustaining national, regional, and global workforce initiatives. Discussion The African Health Profession Regulatory Collaborative for Nurses and Midwives convenes leaders responsible for regulation from 14 countries in East, Central and Southern Africa. It provides a high profile, south-to-south collaboration to assist countries in implementing joint approaches to problems affecting the health workforce. Implemented in partnership with Emory University, the Commonwealth Secretariat, and the East, Central and Southern African College of Nursing, this initiative also supports four to five countries per year in implementing locally-designed regulation improvement projects. Over time, the African Health Regulatory Collaborative for Nurses and Midwives will help to increase the regulatory capacity of health professional organizations and ultimately improve regulation and

    A male African pygmy hedgehog (Atelerix albiventris), estimated to be 3 years old, presented with exophthalmos and fixed abduction of the right eye. Radiographic examination revealed a retrobulbar tumor in the right orbital cavity. The mass was surgically resected but recurred 3 months later and the hedgehog died. There was no gross or microscopic evidence of salivary or lacrimal gland involvement of the tumor at surgery or at necropsy. The histopathologic, immunohistochemical, and ultrastructural findings were those of acinic cell carcinoma, the origin of which was unknown. This is the first known case of acinic cell carcinoma in an African hedgehog. PMID:15048626

    A cross-sectional qualitative descriptive design was used to examine the links among expectations about, experiences with, and intentions toward mental health services. Individual face-to-face interviews were conducted with a purposive sample of 32 African American youth/mothers dyads. Content analysis revealed that positive expectations were linked to positive experiences and intentions, that negative expectations were not consistently linked to negative experiences or intentions, nor were ambivalent expectations linked to ambivalent experiences or intentions. Youth were concerned about privacy breeches and mothers about the harmfulness of psychotropic medication. Addressing these concerns may promote African Americans' engagement in mental health services.

    "This article elaborates upon the problems of the refugee crisis in Africa. With around 4 million refugees, heavily concentrated in particular African nations like Sudan and Somalia, the impacts on the host country can be severe. A model, dealing with the process of refugee migration, with particular reference to impacts on host countries, is developed. Negative impacts include military attacks on communities in the host country. One positive impact is the increase in the number of development-type projects which go beyond the mandate of the U.N. High Commissioner for Refugees. A tentative research agenda on African refugee migration is put forward." PMID:12316228

    2011-06-01

    Astronomical observations used by the ancient people of Africa were developed out of the people's desire to have concrete manifestations of their gods and religious beliefs as well as for time-keeping - day, night and calendar for agricultural and festive seasons. The sky entities (the solar and stellar systems) observed become part of the lives and events here on Earth and so are also part of the context of African literature. This paper examines the ways in which different African peoples have reflected on the role of the sky entities in their literature.

    Full Text Available Abstract Background There is a widespread notion, based on limited information, that in areas of stable malaria transmission most pregnant women with Plasmodium falciparum infection are asymptomatic. This study aim to characterize the clinical presentation of malaria in African pregnant women and to evaluate the adequacy of case management based on clinical complaints. Methods A hospital-based descriptive study between August 2003 and November 2005 was conducted at the maternity clinic of a rural hospital in Mozambique. All women attending the maternity clinic were invited to participate. A total of 2,330 women made 3,437 eligible visits, 3129 were analysed, the remainder were excluded because diagnostic results were unavailable or they were repeat visits. Women gave a standardized clinical history and had a medical exam. Malaria parasitaemia and haematocrit in capillary blood was determined for all women with signs or symptoms compatible with malaria including: presence and history of fever, arthromyalgias, headache, history of convulsions and pallor. Outcome measure was association of malaria symptoms or signs with positive blood slide for malaria parasitaemia. Results In 77.4% of visits pregnant women had symptoms suggestive of malaria; 23% (708/3129 were in the first trimester. Malaria parasitaemia was confirmed in 26.9% (842/3129 of visits. Headache, arthromyalgias and history of fever were the most common symptoms (86.5%, 74.8% and 65.4% presented, but their positive predictive values for malaria parasitaemia were low [28% (27–30, 29% (28–31, and 33% (31–35, respectively]. Conclusion Symptoms suggestive of malaria were very frequent among pregnant women attending a rural maternity clinic in an area of stable malaria transmission. However, less than a third of them were parasitaemic. In the absence of microscopy or rapid diagnostic tests, a large proportion of women, including those in the first trimester of gestation, would be
