    Full Text Available Este artículo propone una aproximación a los censos municipales de Rosario, considerando la estadística como un género de escritura y el proceso de formación histórica de la promoción y proto-marketing urbano. Se estudia la producción y circulación de censos de la provincia de Santa Fe y la ciudad de Rosario desde 1887 hasta 1910. La primera parte del trabajo se concentra en el proceso de difusión del primer censo provincial de Santa Fe en Francia, durante la exposición universal de 1889. Luego se reconstruyen las distintas tentativas de construir oficinas municipales de estadísticas en la ciudad de rosario, movilizadas por la trayectoria del censo de 1887, las crisis sanitarias y los preparativos del censo nacional de 1895. El centro del trabajo considera los censos municipales de rosario de 1900, 1906 y 1910 procurando pasar del problema de la recolección-captación al de la fabricación invención de los datos y de la representatividad al de la performatividad de la estadística como proceso de producción social de saberes y del censo como artefacto cultural.

    Cannibalism is one of our darkest secrets and taboos. It is the ultimate measure of the resilience or otherwise of civilizational processes to extreme conditions. How common was cannibalism in times of famine in the past? Both the nature of the evidence for famine cannibalism and the silences about it challenge the empirical historian to the limit. After a review of the global historiography, this paper attempts to assess the evidence for cannibalism during Ireland's many famines, culminating...

    Full Text Available En septiembre de 1887, Carlos Ameghino, Ayudante Preparador de Paleontología del Museo de La Plata, retornaba de una fructífera expedición a las barrancas del río Santa Cruz, encomendada por el Director de dicha institución, Francisco P. Moreno. Hacia fines de ese año, Florentino Ameghino, Secretario Subdirector del Museo de La Plata, dio a conocer dichos hallazgos describiendo sucintamente 122 taxones de los cuales 110 eran nuevas especies. Al poco tiempo, Florentino era exonerado del Museo, negándosele el acceso a las colecciones. No obstante, en 1889 Ameghino amplió sus descripciones y figuró 74 de los taxones de 1887. En 1891 Florentino Ameghino explicó que sus descripciones y figuras de 1889 se basaron en apuntes y croquis realizados antes de ser exonerado. Llamativamente, muchos de los ejemplares figurados se encuentran depositados en la Colección Naci onal Ameghino, alojada en el Museo Argentino de Ciencias Naturales "Bernardino Rivadavia". En 1980, basándose en este impensado destino de los fósiles, Larry Marshall concluyó que Florentino Ameghino se habría apropiado de una parte de la colección de 1887 y sobre ésta basó su obra de 1889. Las evidencias aquí presentadas avalan la apropiación de ejemplares propuesta por Marshall y brinda un marco de referencia para evaluar la conformación de las series tipo de las especies de 1887.

    The objective of the experiment was to measure the radiation environment inside and outside of the biosatellite COSMOS 1887. For this purpose, detector packages were built up consisting of plastic detectors and nuclear emulsions having different linear energy transfer (LET) thresholds in particle registration, and thermoluminescence dosimeters. Particle fluence rates, LET-spectra and absorbed dose are presented. Absorbed dose is measured as a function of shielding depth. The data are compared with those of other missions. (author)

    1990-01-01

    Twenty two groups of U.S. investigators participated in joint studies of ten male rats flown on the Cosmos 1887 biosatellite. A summary of these studies embracing skeletal muscle, bone, endocrine, neural, intestinal, metabolic, immunology, cardiac, and gonadal investigations is presented. Three general objectives of the rat experiments are outlined - verification of previous observations of the biological responses to microgravity; clarification of the effects of microgravity on both the tissues investigated and the measurements performed; and relation of biological responses to flight duration. It is concluded that the first objective is met fully and the second with a varying degree of success. The confounding effects of overshooting the designated landing site and delayed recovery of the animals largely precluded meeting the last objective. It is also noted that investigations were performed for the first time on brain and spinal cord enzymes, a neurotransmitter, transmitter receptors, hypothalamic regulatory factors, pineal metabolites, atrial granules, liver histology, and jejunal mitotic rate in spaceflight animals.

    To determine the possible biochemical effects of prolonged weightlessness on liver function, samples of liver from rats that had flown aboard Cosmos 1887 were analyzed for protein, glycogen, and lipids as well as the activities of a number of key enzymes involved in metabolism of these compounds and xenobiotics. Among the parameters measured, the major differences were elevations in the glycogen content and hydroxymethylglutaryl-CoA (HMG-CoA) reductase activities for the rats flown on Cosmos 1887 and decreases in the amount of microsomal cytochrome P-450 and the activities of aniline hydroxylase and ethylmorphine N-demethylase, cytochrome P-450-dependent enzymes. These results support the earlier finding of differences in these parameters and suggest that altered hepatic function could be important during spaceflight and/or the postflight recovery period.

    Ludwig Wittgenstein was born in 1889 in Vienna. As a scholar in Cambdrige University, his philosophical achievements are still major regarding the foundations of mathematics and language. In 1939, he took a job as a porter at London Guys' Hospital then under the Blitz. Wittgenstein met Drs. Grant and Reeve who worked in a dedicated "traumatic shock" under the auspices of the Medical Research Council unit, a unit which then moved to the Royal Victoria Infirmary in Newcastle; Wittgenstein followed them as a technician and improved the preparation of fine pieces of histology fixed by paraffin. He also invented a new device to record pulse pressure and paradoxical pulse search in laboratory rats. At the end of the war, he returned to Cambridge until 1949 and died in 1951.

    A complete taxonomic revision of the genus Primnoisis (Isididae) is presented herein, based on original type material of all nominal species and additional specimens from deep-water surveys in sub-temperate and Antarctic waters. A multi-disciplinary approach was used combining morphological characteristics such as colonial branching patterns, polyp structure, sclerite form and arrangement, together with phylogenetic reconstructions using two mitochondrial gene regions (mtMutS and igr1-cox1). The genus Primnoisis is retained with 7 of the 8 nominal species validated (P. antarctica Wright & Studer, 1889, P. rigida Wright & Studer, 1889, P. ambigua Wright & Studer, 1889, P. delicatula Hickson, 1907, P. fragilis Kükenthal, 1912, P. formosa Gravier, 1913 and P. mimas Bayer & Stefani, 1987), with the eighth (P. sparsa Wright & Studer, 1889), synonymised with P. antarctica. In addition, the species Mopsea gracilis Gravier, 1913 is reassigned to Primnoisis and an additional five new species are described (P. chatham n. sp., P. erymna n. sp., P. millerae n. sp., P. niwa n. sp. and P. tasmani n. sp). Most of the species fell into two clear groups, defined both by morphology and genetic grouping, for which two new sub-genera are proposed (P. (Primnoisis) n. subg. and P. (Delicatisis) n. subg.). Three species, P. ambigua, P. mimas and P. tasmani, could not be placed reliably in either sub-genus due to distinctive morphological features or genetic dissimilarity. It was not possible to confirm the monophyly of the genus due to unresolved relationships with the closely related genus Notisis Gravier, 1913 and an undescribed genus of Mopseinae.

    On 8 May 2013, the Chinese Nursing Association joined the International Council of Nurses. It is hoped that by sharing the history of nursing in China, scholars globally can incorporate into current thinking the challenges that Chinese nurses have faced in pursuing educational development and professional acknowledgement. To review the history of nurse education in China between 1887 and 1949 and summarize events marking its development; and to provide historical references for considering contemporary nurse education and discipline development in China. Content analysis using bibliometric and historical research methods on available documentation sources. Milestone events were listed and their historical significance analysed. Nurse education development during this period was affected by three major influences: (1) international nursing collaboration and involvement with Chinese nursing in China and abroad, (2) the determination of leaders to develop nursing as a unique and ethical profession, and (3) the pressure of war and civilian need on the focus of nursing development in China. The development of nurse education in China occurred within an environment of social change, war and international collaboration. Throughout the Modern China period (1887-1949), nursing leadership has guided the growth of nurse education to be responsive to individual and community needs as well as ensuring nurse accountability for conduct and nursing practice. Contemporary Chinese nursing and education owes much to those throughout the Modern China period, who laid the foundations that support the current position and status of nursing. The study displays the benefits and challenges of participation in policy and forums that help nurse scholars and practitioners understand the development of nurse education in China. © 2014 International Council of Nurses.

    Surgeon Major Thomas Heazle Parke (1857-1893) was a doctor from Drumsna, County Roscommon, who after completing his education at the Royal College of Surgeons in Ireland joined the British army as a medical officer. After several years of serving in Ireland and Egypt, he volunteered to be medical officer of the Emin Pasha Relief Expedition of 1887-1889. This was to become Henry Morton Stanley's largest, longest and most controversial African expedition. The epic journey saw Stanley, his eight European officers and 800 African porters take almost 3 years to cross the African continent from West to East via the Congo River, Southern Sudan and Uganda. During this time, Parke had to single-handedly deal with the myriad diseases and injuries that beset the expedition's members. Barely 200 of the Zanzibari, Sudanese and Somali porters survived, and two British officers also perished. In completing the expedition, Parke became the first Irishman to cross Africa, and he had also become the first European to lay eyes on the ' Mountains of the Moon ' or ' Ruwenzori '. He returned home to great acclaim, and was bestowed copious honours and fellowships. His account of the expedition, My Experiences in Equatorial Africa , was a bestseller. However, his own health never recovered from the hardships of his time in Africa, and he died suddenly in 1893. His statue stands outside the Natural History Museum in Dublin. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    This article analyzes the international sanitary conferences that were held in South America in 1873 and 1887, involving the Brazilian Empire and the Republics of Argentina and Uruguay, as an integral part of a series of similar events that took place in Europe and North America starting in the second half of the nineteenth century. The interests of the countries involved, namely trade relations and immigration from Europe - both directly affected by the epidemics - are discussed, and the repercussions of these sanitary agreements on the other countries in the Americas are indicated. The American health conventions in the late nineteenth century represented the first initiatives in the Americas to solve international public health problems.

Although the activity of this school was carried out as part of imperial policy of spiritual domination, promoted by Tsarist autocracy and ecclesiastical authorities, its disciples helped to maintain devotion to the faith and traditions of the Bessarabian Church. This article addresses some aspects of the history of this institution, which was opened in 1889. It highlights its role in the life of the eparchy through the prism of imperial authorities' attitude towards local church music.

    Full Text Available Examination of recent benthic material collected during several cruises in the Gulf of Cadiz (NE Atlantic and the Strait of Sicily (Mediterranean has allowed the taxonomic reassessment of some previously identified specimens belonging to the monogeneric gorgonian family Dendrobrachiidae Brook, 1889. Dendrobrachia fallax Brook, 1889 is the type species of the single genus in this family, and was originally described from Ascension Island (South Atlantic. Subsequently, other authors reported the presence of this species in Cape Verde Islands (north-eastern Atlantic and some Mediterranean localities (Alboran Sea and the Strait of Sicily. The study of the specimen from the Prince of Monaco collections in Cape Verde Islands, and recently collected material from the Gulf of Cadiz (north-eastern Atlantic and in the south of Malta (Mediterranean, materials previously considered as D. fallax, allow us to recognize two undescribed species in this genus. All previous records of D. fallax from the north-eastern Atlantic and Mediterranean should be considered incorrect. Opresko and Bayer (1991 added two additional species of Dendrobrachia. Two new species are described here and compared with their congeners.

    One of the most important problems involving treatments with antibiotics against Aeromonas hydrophila isolated from fishes is that antibiotic resistance develops readily. The antimicrobial activity of chemotherapeutants in isolates from pacu Piaractus mesopotamicus (Holmberg, 1887) and tilapia Oreochromis niloticus (Linnaeus, 1758) was tested by the Kirby-Bauer disk method, over Mueller-Hinton surface agar previously inoculated with 100 µL of bacterial suspensions.

  15. Trends in Ocean Colour and Chlorophyll Concentration from 1889 to 2000, Worldwide

    Marine primary productivity is an important agent in the global cycling of carbon dioxide, a major ‘greenhouse gas’, and variations in the concentration of the ocean's phytoplankton biomass can therefore explain trends in the global carbon budget. Since the launch of satellite-mounted sensors globe-wide monitoring of chlorophyll, a phytoplankton biomass proxy, became feasible. Just as satellites, the Forel-Ule (FU) scale record (a hardly explored database of ocean colour) has covered all seas and oceans – but already since 1889. We provide evidence that changes of ocean surface chlorophyll can be reconstructed with confidence from this record. The EcoLight radiative transfer numerical model indicates that the FU index is closely related to chlorophyll concentrations in open ocean regions. The most complete FU record is that of the North Atlantic in terms of coverage over space and in time; this dataset has been used to test the validity of colour changes that can be translated to chlorophyll. The FU and FU-derived chlorophyll data were analysed for monotonously increasing or decreasing trends with the non-parametric Mann-Kendall test, a method to establish the presence of a consistent trend. Our analysis has not revealed a globe-wide trend of increase or decrease in chlorophyll concentration during the past century; ocean regions have apparently responded differentially to changes in meteorological, hydrological and biological conditions at the surface, including potential long-term trends related to global warming. Since 1889, chlorophyll concentrations have decreased in the Indian Ocean and in the Pacific; increased in the Atlantic Ocean, the Mediterranean, the Chinese Sea, and in the seas west and north-west of Japan. This suggests that explanations of chlorophyll changes over long periods should focus on hydrographical and biological characteristics typical of single ocean regions, not on those of ‘the’ ocean.

    2015-01-01

    This paper examines the role of work in Charcot's clinical teaching focusing on cases of male hysteria in The Tuesday's Lessons from 1887 to 1889. Today, we read the work of Charcot in a retrospective way as having ended in a failure: He would have missed the discovery of the sexual unconscious. From the perspective of psychodynamics of work, it appears an alternative way which was present in Charcot, though unfinished, opening on a possible development of a relationship between psychic and body. The role of work in traumatic hysteria has been forgotten by Freud's posterity and this obliteration continues today.

    Full Text Available By the late nineteenth and early twentieth centuries, clocks and calendars had become everyday objects in homes, classrooms and workplaces. Advertising in the press at the turn of century shows there to have been demand for various sorts of timepiece. This demand spurred the intellectual efforts of inventors who rushed to patent devices either to measure or register the passing of time or simply to satisfy the curiosity these fascinating devices aroused. Five time-measurement-related inventions were patented in the Region of Murcia between 1887 and 1928. Two calendars in 1887, an automated cash machine in 1913 and two inventions in 1928 that exploited the curiosity and the need to measure the time to attract the public’s attention. We discuss these five patents and the contemporary press to get closer to their inventors, achievements and the time in which they lived.A finales del siglo XIX y principios del XX, relojes y calendarios eran objetos de uso cotidiano y se encontraban en hogares, aulas y lugares de trabajo. La publicidad en la prensa del cambio de siglo demuestra la demanda que tenían estos objetos relacionados con la medida del tiempo. Esta demanda espoleó el ingenio de nuestros inventores que se apresuraron a patentar máquinas que controlaban el tiempo, que utilizaban el tiempo como control o simplemente que explotaban la curiosidad y fascinación que provocaban estos aparatos. Entre 1887 y 1928 se patentan en la Región de Murcia cinco ingenios relacionados con la medida del tiempo. Dos calendarios en 1887, un cajero automático en 1913 y dos inventos en 1928 en los que se aprovechan la curiosidad y la necesidad de medir el tiempo para atraer la atención del público.

    Full Text Available This review analyses the study of the Paris World’s Fair of 1889 by Beat Wyss. It considers the strengths and weaknesses of Wyss’s interpretation, but also examines it in the larger context of literature on world fairs. It argues that Wyss’s book exemplifies a common pattern in scholarly studies of world fairs during the nineteenth century, namely, a tendency to focus on their function as forms of cultural representation, i.e. their role in advancing specific notions of regional, national and imperial identity. The review does not dispute that this was a central aspect of the world fairs, but it also points towards the omissions in such studies. Not only were the world fairs founded as a means of promoting liberal ideas of free trade, they were also used to display the latest technologies in a wide array of activities, such as industrial manufacturing, forestry and farming. These subjects are almost never examined in any depth in the literature on world fairs, the result of a partial and limited approach to world fairs. The review argues that for all its strengths, Wyss’s book exemplifies this approach.

    Sir Geoffrey Keynes (1887 - 1982), was a pioneer in the surgery of breast cancer and thymic deseases, n.b. in patients suffering from myastenia gravis. He strongly disapproved of the longstanding dogma of so called radical mastectomy in breast cancer, and advocated a more limited surgical approach, followed by radiation therapy. This was done more than fifty years before breastconserving surgery has become the therapy of choice and against considerable opposition from the surgical establishment of his days. He also became a pioneer in the surgical treatment of myastenia gravis by thymectomy, at a time when there was no real understanding of the pathophysiology of the disease and when considerable controversy existed as to the importance or non importance of concomitant tumour formation in the thymus. Besides being a busy surgeon Sir Geoffrey was a medical historian, writing the biography of among others William Harvey, a bibliographer with a special interest in the poet and artist William Blake and a bibliophil with a large book collection of great value to medical history.

    Full Text Available This paper proposes that the forgotten Earl's Court Spanish Exhibition of 1889 provides a valuable window onto the complex relationship between the British and Spanish Empires at the moment of one's expansion and the other's fragmentation. Part I assesses the limited archival evidence together with media reports from both Spain and Britain to uncover the Exhibition’s origins in London’s Spanish expatriate business community and its takeover by British businessmen with interests in Latin America. Part II reconstructs the Exhibition’s layout and contents in order to explore how the contrasting geocultural logics of Spain’s renewed self-projection as a modern Empire and the longstanding British obsession with Spain’s Islamic past play out in the exhibitionary space and its contents. Part III analyses the rhetorical and imaginative strategies employed in British press coverage of the Exhibition, to argue that their coded representations of Spain and Spanish culture open the door to understanding the Exhibition in the context of Spain’s partial absorption into Britain’s nineteenth-century ‘informal empire.’

  14. Rigor mortis and the epileptology of Charles Bland Radcliffe (1822-1889).

    Science.gov (United States)

    Eadie, M J

    2007-03-01

    Charles Bland Radcliffe (1822-1889) was one of the physicians who made major contributions to the literature on epilepsy in the mid-19th century, when the modern understanding of the disorder was beginning to emerge, particularly in England. His experimental work was concerned with the electrical properties of frog muscle and nerve. Early in his career he related his experimental findings to the phenomenon of rigor mortis and concluded that, contrary to the general belief of the time, muscle contraction depended on the cessation of nerve input, and muscle relaxation on its presence. He adhered to this counter-intuitive interpretation throughout his life and, based on it, produced an epileptology that was very different from those of his contemporaries and successors. His interpretations were ultimately without any direct influence on the advance of knowledge. However, his idea that withdrawal of an inhibitory process released previously suppressed muscular contractile powers, when applied to the brain rather than the periphery of the nervous system, permitted Hughlings Jackson to explain certain psychological phenomena that accompany or follow some epileptic events. As well, Radcliffe was one of the chief early advocates for potassium bromide, the first effective anticonvulsant.

    1991-01-01

    The cellular compartmentalization of the cyclic AMP-receptor proteins in heart ventricular tissue obtained from rats flown on the Cosmos 1887 is determined. Photoaffinity labeling of soluble and particular cell fractions with a (32P)-8-azido analog of cyclic AMP is followed by electrophoretic separation of the proteins and by autoradiographic identification of the labeled isoforms of cAPK R subunits. It is shown that RII in the particulate subcellular fraction was significantly decreased in heart cells from rats in the flight group when compared to controls. Protein banding patterns in both the cytoplasmic fraction and in a fraction enriched in chromatin-bound proteins exhibited some variability in tissues of individual animals, but showed no changes that could be directly attributed to flight conditions. No significant change was apparent in the distribution of RI or RII cyclic AMP binding in the soluble fractions. It is inferred that the cardiac cell integrity or its protein content is not compromised under flight conditions.

    This article aims at analyzing the intimate diary of José Vieira Couto de Magalhães, a XIX century politician and thinker. The diary under analysis was written between 1880 and 1887. The author’s intimate writing encompasses a multitude of issues, including his disregard for women, his fears, anguish, business, his personal and intimate relationships, concerns as to caring for the body, and, in particular – and of special interest for this article – a feverish sexuality which is e...

    1985-12-01

    Born into a Boston Irish family, Marcella Imelda O'Grady was the first woman graduate in biology from MIT (1885) where she came under the influence of two recent PhD graduates of Johns Hopkins University, William Townsend Sedgwick and Edmund Beecher Wilson. She taught science at Bryn Mawr School for girls in Baltimore 1885 to 1887 and was teaching assistant with E B Wilson at Bryn Mawr College for women in Bryn Mawr, Pennsylvania, 1887 to 1889. From 1889 to 1896 she headed the Department of Biology at Vassar College for women in Poughkeepsie, New York. On the recommendation of E B Wilson (who from the first edition in 1896 dedicated his famous book The cell in development and inheritance to Boveri) Marcella went to Würzburg to spend a sabbatical with Boveri. One year later she married Boveri and during the next 18 years until Boveri's untimely death in 1915 she was her husband's close scientific collaborator, especially in his work at the marine zoological stations in Naples and Villefranche, France. She also acquired (from Freiburg) the doctorate she had unsuccessfully attempted to get at Johns Hopkins. Marcella returned to the United States in 1926 and headed the Biology Department at Albertus Magnus College in New Haven. She was there in 1929 when her English translation of her husband's 1914 monograph advancing the chromosome theory of cancer was published. The translation did much to bring that theory to the attention of a wider audience which has thereby been able to rediscover Boveri, despite lack of a reading knowledge of German. Boveri's theory was based on the views that cancer is a cellular problem, cancers originate from a single cell, this cell has an abnormality of its chromosomal constitution, and the chromosomal abnormality which is passed on to all the descendants of the cell of origin is the cause of rapid cell proliferation.

  4. Rupture of the Pitáycachi Fault in the 1887 Mw 7.5 Sonora, Mexico earthquake (southern Basin-and-Range Province): Rupture kinematics and epicenter inferred from rupture branching patterns

    Suter, Max

    2015-01-01

    During the 3 May 1887 Mw 7.5 Sonora earthquake (surface rupture end-to-end length: 101.8 km), an array of three north-south striking Basin-and-Range Province faults (from north to south Pitáycachi, Teras, and Otates) slipped sequentially along the western margin of the Sierra Madre Occidental Plateau. This detailed field survey of the 1887 earthquake rupture zone along the Pitáycachi fault includes mapping the rupture scarp and measurements of surface deformation. The surface rupture has an endpoint-to-endpoint length of ≥41.0 km, dips 70°W, and is characterized by normal left-lateral extension. The maximum surface offset is 487 cm and the mean offset 260 cm. The rupture trace shows a complex pattern of second-order segmentation. However, this segmentation is not expressed in the 1887 along-rupture surface offset profile, which indicates that the secondary segments are linked at depth into a single coherent fault surface. The Pitáycachi surface rupture shows a well-developed bipolar branching pattern suggesting that the rupture originated in its central part, where the polarity of the rupture bifurcations changes. Most likely the rupture first propagated bilaterally along the Pitáycachi fault. The southern rupture front likely jumped across a step over to the Teras fault and from there across a major relay zone to the Otates fault. Branching probably resulted from the lateral propagation of the rupture after breaching the seismogenic part of the crust, given that the much shorter ruptures of the Otates and Teras segments did not develop branches.

    Walther Gerlach (1889-1979) was born in Wiesbaden-Biebrich and studied physics at the Eberhard-Karls-Universitaet in Tuebingen, where he did his doctorate in February 1912. In this work, there is no room for a complete biography either as it would exceed the scope of this thesis. It is restricted to the first part of his life, which is treated in detail. The aim of this thesis is to understand Walther Gerlach's development into a successful physicist, to find out what influenced him and to identify his achievements during this period until 1925. To gain a greater insight into his personal development the circumstances in his family as well as the conditions regarding his education in school and university will be investigated. His way of dealing with friends and colleagues is analyzed and his approaches to physical problems discussed. The personality of the physicist Gerlach rather emerges from the sum of details observed and examples quoted. However, some events in his life can be named, which show that his achievements did not happen by chance but are connected to his career. This thesis ends more or less with the beginning of the year 1925, when Gerlach accepted the chair for physics in Tuebingen.

Desde a introdução e consolidação dos princípios que definiram a oncologia experimental, detectam-se fases distintas de produção científica, oscilando entre a comprovação de teorias dominantes e a aplicação de métodos de criação artificial da doença. Propõe-se breve sistematização da orientação dos estudos dedicados à oncologia, organizados em patamares de investigação predominantes.This article deals with the bio-medical investigation of cancer studies in Portugal between 1889 and 1945. By examining the main works produced between the end of the nineteenth century and the middle of the twentieth century, it has been possible to illuminate and define a field of scientific endeavour which has been the scope of little study to date. Starting from the introduction and consolidation of the defining principles of experimental oncology, distinct phases can be discerned in the production of scientific material, alternating between support for the dominant theories and the application of methods for artificially creating the disease. In accordance with the principal phases of investigation, a brief systematic overview of the scope of these oncological studies is presented.

    Full Text Available The article analyses the evolution of Brazilian tariff policy between 1844 and 1889. At first a review of the various tariff schedules adopted during the period is made, with their main features highlighted. The next section seeks to assess the impact of tariff policy on the degree of protection afforded to the domestic sector. To that effect, three types of exercises are carried out: first, the “real cost of imports” and its determinants are calculated; we then calculate coefficients of partial correlation between the quantity of imports, GDP, price of imports, the rate of exchange and import tariffs; finally, we estimate econometrically import demand equations. The exercises reveal that during the II Reign tariffs were important in explaining variations in total imports, although this importance diminished after 1869.

    Tuberculosis (TB) mortality declined in the northern hemisphere over the last 200 years, but peaked during the Russian (1889) and the Spanish (1918) influenza pandemics. We studied the impact of these two pandemics on TB mortality. We retrieved historic data from mortality registers for the city of Bern and countrywide for Switzerland. We used Poisson regression models to quantify the excess pulmonary TB (PTB) mortality attributable to influenza. Yearly PTB mortality rates increased during both influenza pandemics. Monthly influenza and PTB mortality rates peaked during winter and early spring. In Bern, for an increase of 100 influenza deaths (per 100,000 population) monthly PTB mortality rates increased by a factor of 1.5 (95%Cl 1.4-1.6, ppandemic. Nationally, the factor was 2.0 (95%Cl 1.8-2.2, ppandemics. We demonstrate excess PTB mortality during historic influenza pandemics in Switzerland, which supports a role for influenza vaccination in PTB patients in high TB incidence countries.

  10. S-wave attenuation in northeastern Sonora, Mexico, near the faults that ruptured during the earthquake of 3 May 1887 Mw 7.5.

    We used a new data set of relocated earthquakes recorded by the Seismic Network of Northeastern Sonora, Mexico (RESNES) to characterize the attenuation of S-waves in the fault zone of the 1887 Sonora earthquake (M w 7.5). We determined spectral attenuation functions for hypocentral distances (r) between 10 and 140 km using a nonparametric approach and found that in this fault zone the spectral amplitudes decay slower with distance at low frequencies (f < 4 Hz) compared to those reported in previous studies in the region using more distant recordings. The attenuation functions obtained for 23 frequencies (0.4 ≤ f ≤ 63.1 Hz) permit us estimating the average quality factor Q S  = (141 ± 1.1 )f ((0.74 ± 0.04)) and a geometrical spreading term G(r) = 1/r (0.21). The values of Q estimated for S-wave paths traveling along the fault system that rupture during the 1887 event, in the north-south direction, are considerably lower than the average Q estimated using source-station paths from multiple stations and directions. These results indicate that near the fault zone S waves attenuate considerably more than at regional scale, particularly at low frequencies. This may be the result of strong scattering near the faults due to the fractured upper crust and higher intrinsic attenuation due to stress concentration near the faults.

    The American Journal of Psychology (AJP) was the first academic journal in the United States dedicated to the "new" scientific form of the discipline. But where did the journal's founding owner/editor, G. Stanley Hall, find the "psychologists" he needed to fill the pages of such a venture 1887, when he was still virtually the only professor of psychology in the country? To investigate this question we used the substantive vocabularies of every full article published in AJP's first 14 volumes to generate networks of verbally similar articles. These networks reveal the variety of research communities that Hall drew on to launch and support the journal. Three separate networks, corresponding to 3 successive time blocks, show how Hall's constellation of participating research communities changed over AJP's first 17 years. Many of these communities started with rather nebulous boundaries but soon began to differentiate into groups of more distinct specialties. Some topics declined over time, but new ones regularly appeared to replace them. We sketch a quasievolutionary model to describe the intellectual ecology of AJP's early years.

    Dr. Jules Cotard (1840-1889) was a Parisian neurologist who first described the délire des négations. Cotard's syndrome or Cotard's delusion comprises any one of a series of delusions ranging from the fixed and unshakable belief that one has lost organs, blood, or body parts to believing that one has lost one's soul or is dead. In its most profound form, the delusion takes the form of a professed belief that one does not exist. Encountered primarily in psychoses such as schizophrenia and bipolar disorder, Cotard's syndrome has also been described in organic lesions of the nondominant temporoparietal cortex as well as in migraine. Cotard's delusion is the only self-certifiable syndrome of delusional psychosis. Jules Cotard, a Parisian neurologist and psychiatrist and former military surgeon, was one of the first to induce cerebral atrophy by the experimental embolization of cerebral arteries in animals and a pioneer in studies of the clinicopathologic correlates of cerebral atrophy secondary to perinatal and postnatal pathologic changes. He was the first to record that unilateral cerebral atrophy in infancy does not necessarily lead to aphasia and was also the pioneer of studies of altered conscious states in diabetic hyperglycemia.

    Full Text Available The Palais des Machines of the Paris Universal Exposition of 1889, designed by the architect Charles Louis Ferdinand Dutert (1845-1906 and the engineer Victor Contamin (1840-1893, is undoubtedly an icon of the 19th century architecture: its powerful spatiality, its portentous structure and its straightforward tectonics have rightly received high praise by critics and architects from the second half of the 20th century. However, critical tradition and historiography from the end of the last century have frequently offered a biased interpretation of this work, aimed at underlining certain architectonic values for then presenting them as a direct product of the author’s will. The aim of this article is to explain, altogether and with maximum transparency, how the conjunction between certain circumstantial issues and the will/ability of both authors made possible the construction of one of the most important works of the nineteenth-century architecture. To achieve this, the three most celebrated architectural aspects of the building are analysed: the huge scale of the central space, the particular structural system chosen and the uneven usage of ornament.

  16. Rewriting the Landform History of One of Africa's Three Largest Basins

    The Kalahari Basin in southern Africa - one of the largest basins in Africa, along with the Congo and Chad basins - has attracted attention since David Livingstone traveled through the area in the 1840s. It is a semiarid desert with a large freshwater swampland known as the Okavango Swamp (150 km radius). This prominent megafan (a fan with radii >100 km), with its fingers of dark green forests projecting into the dun colors of the dunes of the Kalahari semi-desert, has been well photographed by astronauts over the years. The study area in the northern Kalahari basin is centered on the Okavango megafan of northwest Botswana, whose swampland has become well known as an African wildlife preserve of importance to biology and tourism alike. The Okavango River is unusual because it has deposited not one but two megafans along its course: the Okavango megafan and the Cubango megafan. The Okavango megafan is one of only three well-known megafans in Africa. Megafans on Earth were once thought to be rare, but recent research has documented 68 in Africa alone. Eleven megafans, plus three more candidates, have been documented in the area immediately surrounding the Okavango feature. These 11 megafans occupy the flattest and smoothest terrains adjacent to the neighboring upland and stand out as the darkest areas in the roughness map of the area. Megafan terrains occupy at least 200,000 sq km of the study area. The roughness map shown is based on an algorithm used first on Mars to quantify topographic roughness. Research of Earth's flattest terrains is just beginning with the aid of such maps, and it appears that these terrains are analogous to the flattest regions of Mars. Implications: 1. The variability in depositional style in each subbasin may apply Africa-wide: rift megafan length is dominated by rift width, whereas Owambo subbasin megafans are probably controlled by upland basin size; Zambezi subbasin megafans appear more like foreland basin types, with the position of

The antimicrobial activity of chemotherapeutants in isolates from pacu Piaractus mesopotamicus (Holmberg, 1887 and tilapia Oreochromis niloticus (Linnaeus, 1758 was tested by the Kirby-Bauer disk method, over Mueller-Hinton surface agar previously inoculated with 100 µL of bacterial suspensions. After regular incubation, isolates from tilapia and pacu were uniformly resistant to amoxicillin, ampicillin, lincomycin, novobiocin, oxacillin, penicillin, and trimetoprim+sulfametoxazole. The A. hydrophila type strain presented resistance to the same antimicrobial substances and also against rifampicin; the bacterial isolate from pacu were the only strain resistant to tetracyclin. Isolates from both pacu and tilapia had intermediate reaction with erytromycin. The use of drugs in commercial fish farms in Brazil can favor the development of resistant bacterial strains in native fish species as already observed for exotic species, commercially produced for longer time.Um dos maiores problemas envolvendo o tratamento com antibióticos contra Aeromonas hydrophila isolada de peixes confinados é a rápida resistência ao antibiótico desenvolvida pela bactéria.

    Foot-and-mouth disease virus (FMDV) causes a highly contagious disease of cloven-hooved animals that poses a constant burden on farmers in endemic regions and threatens the livestock industries in disease-free countries. Despite the increased number of publicly available whole genome sequences, FMDV data are biased by the opportunistic nature of sampling. Since whole genomic sequences of Southern African Territories (SAT) are particularly underrepresented, this study sequenced 34 isolates from eastern and southern Africa. Phylogenetic analyses revealed two novel genotypes (that comprised 8/34 of these SAT isolates) which contained unusual 5′ untranslated and non-structural encoding regions. While recombination has occurred between these sequences, phylogeny violation analyses indicated that the high degree of sequence diversity for the novel SAT genotypes has not solely arisen from recombination events. Based on estimates of the timing of ancestral divergence, these data are interpreted as being representative of un-sampled FMDV isolates that have been subjected to geographical isolation within Africa by the effects of the Great African Rinderpest Pandemic (1887–1897), which caused a mass die-out of FMDV-susceptible hosts. These findings demonstrate that further sequencing of African FMDV isolates is likely to reveal more unusual genotypes and will allow for better understanding of natural variability and evolution of FMDV.

    Full Text Available A idade e o crescimento do linguado-branco Paralichthys patagonicus (Jordan, 1889 foram estudados a partir de amostras obtidas da pesca comercial no sul do Brasil entre 1989 e 1991. As idades foram determinadas sobre cortes transversais de otólitos de 460 exemplares. A análise do tipo de bordo e dos incrementos marginais dos otólitos mostrou que, a cada ano ocorre a formação de uma zona translúcida e uma zona opaca nos otólitos. As "remeas atingem maiores tamanhos e idades (630 mm, 13 anos do que os machos (527 mm, 11 anos. Os parâmetros da equação de von Bertalanffy que representaram o crescimento em comprimento total das remeas foram: CT∞,= 623,0 mm, K= 0,279 e to= -0,243 anos; dos machos: CT∞,= 534,1 mm, K= 0,214 e t o = -1,589 anos e dos sexos agrupados: CT∞, = 609,1 mm, K = 0,255 to = - 0,462 anos. Os incrementos anuais em peso por idades aumentam até o final do quarto ano de vida quando a maioria já atingiu a primeira maturação sexual e ambos sexos alcançaram cerca de 30% do peso e 70% do comprimento assintóticos. Esta espécie é susceptível à sobrepesca de crescimento porque o redirecionamento do metabolismo do crescimento somático para a reprodução é gradativo e o potencial de crescimento após a maturação sexual é relativamente alto.Age and growth of the white flounder Paralichthys patagonicus (Jordan, 1889 were studied using sliced sagittae otoliths of 460 specimens collected from the commercial fishery along southem Brazil (1989 to 1991.

    In 1887, only five years after Jean-Martin Charcot was awarded the Head of Neurology at "La Salpetrière" in Paris, José María Ramos Mejía became the first professor of Neurology in South America, at the School of Medicine of the University of Buenos Aires. Ramos Mejía convoked three assistants, the neuropathologist Christofredo Jakob, the clinician José A. Esteves and José Ingenieros. Hence it followed that Neurology in Argentina took a stand based on a clinical neurology-neuropathology approach (1941-1987) followed by a clinical-semiological attitude, finally inserting itself within the modern times (1987-present) by creating subspecialties. Throughout its history, Argentina has made remarkable contributions to Neurology, such as the diagnosis and pathogenesis of the nervous system involvement occurring in some regional endemic disorders -for instance, Chagas' disease-, the clinical approach to the diagnosis of dementias, and the pathogenesis of extrapyramidal illnesses and other primary degenerative diseases of the central nervous system, mainly amyotrophic lateral sclerosis. On the other hand, in recent years globalization allowed neurologists to participate in international cooperative projects, favoring a swifter development in the practice of this discipline.

Charles learned pharmacy in Paris. Coming back to Angers he bought a chemist’s shop. In 1871 he became the chief pharmacist of the Hôtel-Dieu. In 1857 he joined the Academic Society of Angers and presented many consequent papers between them one can find notes concerning the history of the Angers’s pharmacists. Its researches relate to pharmacology, mineralogy, hydrology and even philology.

  5. When did legong start? A reply to Stephen Davies

    Adrian Vickers

    2009-05-01

    Full Text Available Stephen Davies has recently opened up new ways of looking at the history of Bali’s premier dance form, legong. He has argued that legong started in the late nineteenth century, more specifically after 1887, probably in 1889, and that it is primarily derived from a form which Balinese presently call andir. Davies’ article involves a substantial reconsideration of the canonical nature of certain dance forms in Bali. The evidence Davies used is largely oral history. What is missing from Davies’ account is evidence from closer to the time period, evidence that can allow us to fix the date of the origins of legong more closely, and also to understand precisely what its performative and musical associations and origins might be. This evidence is present in Balinese and Dutch-language sources, and while there are limitations to these sources, they certainly modify Davies’ thesis.

    In this paper, we demonstrate ∼2 μm lasing in Tm3+-doped fluorotellurite microstructured fibers. The Tm3+-doped fibers are based on TeO2-BaF2-Y2O3 glasses and fabricated by using a rod-in-tube method. Under the pump of a 1570 nm Er3+-doped fiber laser, lasing at 1887 nm is obtained in a ∼42.5 cm long Tm3+-doped fiber with a threshold pump power of 94 mW. As the pump power increases to 780 mW, the obtained maximum unsaturated power reaches up to ∼408 mW with a slop efficiency of ∼58.1%. This result indicates that the Tm3+-doped fluorotellurite fibers are promising gain media for ∼2 μm fiber lasers.

    Walther Gerlach (1889-1979) was born in Wiesbaden-Biebrich and studied physics at the Eberhard-Karls-Universitaet in Tuebingen, where he did his doctorate in February 1912. In this work, there is no room for a complete biography either as it would exceed the scope of this thesis. It is restricted to the first part of his life, which is treated in detail. The aim of this thesis is to understand Walther Gerlach's development into a successful physicist, to find out what influenced him and to identify his achievements during this period until 1925. To gain a greater insight into his personal development the circumstances in his family as well as the conditions regarding his education in school and university will be investigated. His way of dealing with friends and colleagues is analyzed and his approaches to physical problems discussed. The personality of the physicist Gerlach rather emerges from the sum of details observed and examples quoted. However, some events in his life can be named, which show that his achievements did not happen by chance but are connected to his career. This thesis ends more or less with the beginning of the year 1925, when Gerlach accepted the chair for physics in Tuebingen.

  12. A premodern legacy: the "easy" criminalization of homosexual acts between women in the Finnish Penal Code of 1889.

    Science.gov (United States)

    Löfström, J

    1998-01-01

    Homosexual acts between women were criminalized in Finland in the 1889 Penal Code which also criminalized men's homosexual acts for the first time explicitly in Finnish legislation. The inclusion of women in the Penal Code took place without much ado. In the article it is argued that the uncomplicated juxtaposing of men and women was due to the legacy of a cultural pattern where man and woman, as categories, were not in an all-pervasive polarity to each other, for example, in sexual subjectivity. A cultural pattern of low gender polarization was typical of preindustrial rural culture, and it can help us apprehend also certain other features in contemporary Finnish social and political life, for example, women obtaining a general franchise and eligibility for the parliament first in the world, in 1906. A modern image of "public man" and "private woman" was only making its way in Finnish society; hence, there was not much anxiety at women's entry in politics, or, for that matter, at their potential for (homo)sexual subjectivity becoming recognized publicly in criminal law.

    Artemia (Brine shrimp) cysts and tobacco seeds, dormant biological material devoid of metabolic activity, were flown aboard the Soviet Biocosmos 1887 in order to investigate the effects of cosmic rays. Artemia cysts and tobacco seeds were used in bulk or in monolayers sandwiched with track detectors. Biological and physical units were located outside and inside the spacecraft. Stacks included lead shielding in order to expose the objects to different doses of radiation. Total dosimetry was performed using thermoluminescent detectors. In spite of low levels of doses, the space flight resulted in a decrease in developmental capacity of Artemia cysts, and in a higher mutation rate in tobacco seeds. The more obvious responses occurred, in both cases, in biological objects exposed to the highest doses. These results are compared to those of previous space experiments. (author).

  16. Reevaluation of the macroseismic effects of the 1887 Sonora, Mexico earthquake and its magnitude estimation

    Suárez, Gerardo; Hough, Susan E.

    2008-01-01

    The Sonora, Mexico, earthquake of 3 May 1887 occurred a few years before the start of the instrumental era in seismology. We revisit all available accounts of the earthquake and assign Modified Mercalli Intensities (MMI), interpreting and analyzing macroseismic information using the best available modern methods. We find that earlier intensity assignments for this important earthquake were unjustifiably high in many cases. High intensity values were assigned based on accounts of rock falls, soil failure or changes in the water table, which are now known to be very poor indicators of shaking severity and intensity. Nonetheless, reliable accounts reveal that light damage (intensity VI) occurred at distances of up to ~200 km in both Mexico and the United States. The resulting set of 98 reevaluated intensity values is used to draw an isoseismal map of this event. Using the attenuation relation proposed by Bakun (2006b), we estimate an optimal moment magnitude of Mw7.6. Assuming this magnitude is correct, a fact supported independently by documented rupture parameters assuming standard scaling relations, our results support the conclusion that northern Sonora as well as the Basin and Range province are characterized by lower attenuation of intensities than California. However, this appears to be at odds with recent results that Lg attenuation in the Basin and Range province is comparable to that in California.

    Abstract The semi-aquatic freshwater earthworm genus Glyphidrilus Horst, 1889 from Thailand was investigated based on extensive recent collecting. The species in this genus were characterized by their external and internal morphological characters of the location of wings, genital openings, genital organ structures and their locations, as well as the dimensions of body length and number of segments. Several type specimens were compared with both previous and newly collected materials. Ten new species are described from several river systems in Thailand; as Glyphidrilus borealis sp. n., Glyphidrilus chaophraya sp. n., Glyphidrilus chiensis sp. n., Glyphidrilus huailuangensis sp. n., Glyphidrilus kratuensis sp. n., Glyphidrilus quadratus sp. n., Glyphidrilus trangensis sp. n., Glyphidrilus wararamensis sp. n., Glyphidrilus vangthongensis sp. n. and Glyphidrilus vesper sp. n. Each species is endemic to a single river system. All 26 previously described species are re-described, and eight lectotypes have been designated. An identification key and a morphological comparison summary are provided. PMID:23653518

    Full Text Available This article aims at analyzing the intimate diary of José Vieira Couto de Magalhães, a XIX century politician and thinker. The diary under analysis was written between 1880 and 1887. The author’s intimate writing encompasses a multitude of issues, including his disregard for women, his fears, anguish, business, his personal and intimate relationships, concerns as to caring for the body, and, in particular – and of special interest for this article – a feverish sexuality which is expressed in dreams, revealing a strong homoerotic desire. Living in a period in which homosexuals were badly regarded by society, were considered “propagators of sin”, by the Church, and as carriers of “sexual instinct” diseases in medical discourse, José Vieira described his erotic dreams with partners of the same sex in a natural and spontaneous manner, without attributing any negative labelling to these dreams.

    Full Text Available Abstract This study provides the first contribution of the biology and life table of Aphis forbesi Weed, 1889 (Hemiptera: Aphididae, an important strawberry pest throughout the world. This species lives in the crown and leaf petioles of the plant. It is difficulty to rear this species in laboratory due to protocooperation with ants observed only in the field. We studied the life cycle of A. forbesi on the leaves of the Albion strawberry cultivar at 25 ± 2 °C, 60 ± 10% relative humidity, and a 12-h photophase. The experiment was randomised with 100 replicates. The parameters of the fertility life table were calculated using TabVida. In the population studied, 25% and 46% had four and three instars, respectively. A mean of 1.43 nymphs per female per day was generated. The mean reproductive period was seven days and the mean longevity was 10 days. In every 11 days there is a generation of A. forbesi, where each female has the potential to generate between 6 to 9 individuals daily, increasing its population by 1.2 times. The average life cycle was 16.8 days. High viability observed in all instars and the resulting values of R0, rm and λ suggest that A. forbesi has the capacity to increase their numbers in a short period of time, while generating high populations in strawberry crops, requiring differential management.

  3. Rickets in lion cubs at the London Zoo in 1889: some new insights.

    2009-05-01

    In 1889, when Dr John Bland-Sutton, a prominent surgeon in London, England, was consulted concerning fatal rickets in more than 20 successive litters of lion cubs at the London Zoo, he evaluated the role of diet relative to the development of rickets. He prescribed goat meat and bones and cod-liver oil to be added to the lean horse-meat diet of the cubs and their mothers. Rickets reversed, the cubs survived, and litters were reared successfully. In classic controlled studies conducted in puppies and young rats 3 decades later, the crucial role of calcium, phosphate, and vitamin D in both prevention and therapy of rickets was elucidated. Later studies led to the identification of the structural features of vitamin D. Although the Bland-Sutton interventional diet obviously provides calcium and phosphate from bones and vitamin D from cod-liver oil, other benefits of this diet were not initially recognized. Chewing bones promotes tooth and gum health and removes bacteria-laden tartar. Cod-liver oil also contains vitamin A, which is essential for the prevention of infection and for epithelial cell health. Taurine-conjugated bile salts are also necessary for the intestinal absorption of fat-soluble vitamins, including A and D. Moreover, unlike dogs and rats, all feline species are unable to synthesize taurine yet can only conjugate bile acids with taurine. This sulfur-containing beta-amino acid must be provided in the carnivorous diet of a large cat. Taurine-conjugated bile salts were provided in the oil cold-pressed from cod liver. The now famous Bland-Sutton "experiment of nature," namely, fatal rickets in lion cubs, was cured by the addition of minerals and vitamin D. However, gum health and the presence of taurine-conjugated bile salts undoubtedly permitted absorption of vitamin A and D, the latter promoting the cure of rickets.

    Full Text Available This paper addresses the primary public inspection, particularly that exercised by parish inspectors, considered as one of the forms of manifestation of the policy on education. A research about reports and official letters concerning the primary public education in Paraná in the provincial period (1853-1889 shows ordinary school issues and, especially, the relationship between teachers and the authorities responsible for the administration and control of the work in schools. This paper aims to deep the knowledge on parish inspection and literary council, as components of the inspection that used to be present in the relations between teachers and inspectors. The methodology includes documental research, analysis of sources and crossing of information from reports and official letters with the provincial legislation of Paraná. We can conclude that, in spite of a relative legal organization when it comes to the distribution of administrative functions and control over public instruction, the latter remained quite precarious at the end of the provincial period, since only with the advance of social relations of production of material life the school would become necessary.

    The famous report by engineers Drabbe and Badon Ghijben (1889), on an intended well drilling near Amsterdam (the Netherlands), was one of the key documents that contributed to the Ghijben-Herzberg formula, which links water-table elevation to the depth of the freshwater-saltwater interface in coastal aquifers. The report has been often cited but no English translation has appeared in the literature to date. The aim of this annotated translation of the report is to provide the international scientific community with easier access than was hitherto the case, plus electronic access to the original in Dutch. A brief introduction to the report is provided, followed by a translation that follows the original text as closely as possible.

    Diet has long been associated with a risk of insulin resistance and poor glycemic control. We sought to investigate the association between food groups and indices of glycemic control in adults without type 2 diabetes and cardiovascular disease. During 2001 - 2002 we randomly enrolled 1514 men (18-87 years old) and 1528 women (18-89 years old) without evidence of cardiovascular disease from the Attica area of Greece. Of them, 118 men and 92 women were excluded from the present analysis due to a history of diabetes mellitus (type 2). Fasting blood glucose and insulin levels were measured, while dietary habits were evaluated through a semi-quantitative food frequency questionnaire. Red meat consumption was positively associated with hyperglycemia (p = 0.04), hyperinsulinemia (p = 0.04), and HOMA levels (p = 0.03), even after adjusting for BMI and various other potential confounders. The intake of fruits, vegetables, legumes, yogurt and other dairy products was not associated with levels of glycemic control indices. A higher consumption of red meat and its products may aggravate hyperinsulinemia and insulin resistance in non-diabetic people.

    Full Text Available During the last two decades of the nineteenth century, two figures of Cuban origin help to transform La estrella de Panamá, a small newspaper from the hard to reach Isthmus. José Gabriel Duque with the editorial collaboration of Domingo A. Galdós, the son of Benito Pérez Galdós’ first cousin, will include new cultural material to the paper. This article studies Benito’s presence in this newspaper starting in 1889 which begins a transatlantic dialogue with his American relative and with the readers of the paper. Several phases of this connection are discussed as well as works such as Venecia, Vergara, Los condenados and Electra. The essay concludes with 1901 when Domingo Galdós leaves the newspaper to return to Cuba after the war of independence, having fulfilled the tasks imposed on him by José Martí.Durante las últimas dos décadas del siglo diecinueve, dos figuras procedentes de Cuba transforman La estrella de Panamá, un pequeño periódico del lejano Istmo. José Gabriel Duque con la colaboración editorial de Domingo A. Galdós, hijo de un primo hermano de Benito Pérez Galdós, irá añadiendo elementos culturales al periódico. Este ensayo estudia la presencia de don Benito en este periódico, que comienza en 1889 cuando entabla un diálogo trasatlántico con su pariente americano y los lectores del periódico. Se apuntan varias facetas de este diálogo y se estudia la presencia de obras tales como Venecia, Vergara, Los condenados y Electra. Este análisis abarca hasta 1901 cuando Domingo Galdós deja el periódico para regresar a Cuba después de la guerra y habiendo cumplido los dictados de José Martí.

    Full Text Available Los análisis históricos contables permiten evidenciar, bajo el marco de la teoría de la agencia, los conflictos de intereses que se producen en una organización. Nuestro objetivo, con un estudio longitudinal, basado en fuentes primarias, es comprobar cómo se regula una relación de agencia a través de contratos formales, y el papel que asume la contabilidad. El caso en el que nos basamos, y que puede ser una importante contribución en ese sentido, es el del arrendamiento del monopolio estatal del tabaco a una empresa privada, desde el inicio de la gestión (1887 hasta que empieza a desaparecer esta actividad monopolística (1986. Nuestros hallazgos ponen de manifiesto que los contratos establecidos permiten un gran control del principal sobre el agente y que no se cumplen todas las condiciones que deben darse para considerarlos «un buen acuerdo contractual». Por otro lado, la contabilidad aparece como un instrumento clave para el control del Estado sobre las empresas arrendatarias. Nuestra principal conclusión es que el agente es quien asume mayor riesgo en el arrendamiento, y el principal mantiene un comportamiento oportunista durante todo el periodo, lo que contradice los planteamientos más generalizados de la teoría y permite relajar sus asunciones iniciales.

  14. Antarctic-Wide Array of High-Resolution Ice Core Records Reveals Pervasive Lead Pollution Began in 1889 and Persists Today

    Interior Antarctica is among the most remote places on Earth and was thought to be beyond the reach of human impacts when Amundsen and Scott raced to the South Pole in 1911. Here we show detailed measurements from an extensive array of 16 ice cores quantifying substantial toxic heavy metal lead pollution at South Pole and throughout Antarctica by 1889 - beating polar explorers by more than 22 years. Unlike the Arctic where lead pollution peaked in the 1970s, lead pollution in Antarctica was as high in the early 20th century as at any time since industrialization. The similar timing and magnitude of changes in lead deposition across Antarctica, as well as the characteristic isotopic signature of Broken Hill lead found throughout the continent, suggest that this single emission source in southern Australia was responsible for the introduction of lead pollution into Antarctica at the end of the 19th century and remains a significant source today. An estimated 660 t of industrial lead have been deposited over Antarctica during the past 130 years as a result of mid-latitude industrial emissions, with regional-to-global scale circulation likely modulating aerosol concentrations. Despite abatement efforts, significant lead pollution in Antarctica persists into the 21st century.

  15. Regional responses: Africa

    International Nuclear Information System (INIS)

    Wereko-Brobby, C.Y.

    1992-01-01

    In this paper, the author presents the theory that for Africa to work towards reduction of global warming, it must first address its environmental problems; i.e. land use, deforestation, desertification, poverty and hunger. He argues that Africa should aim for growth in the productivity and quantity of energy use. The following suggestions were made: Africa must shift from low-quantity biomass to secondary sources in the short term; developed countries must avoid pushing experimental and frontier technologies on Africa; with financial and technical help, Africa could develop its largely untapped reserves of hydropower. Nuclear power should not be an option because reliable production is not possible at present

    Stephen A. Royle

    2016-06-01

    Full Text Available This article deals with the encounters between a traditional Korean rural and island population and western military forces when the British navy occupied Geomundo, an archipelago known to them as Port Hamilton, for 22 months between 1885 and 1887. The paper first outlines the sometimes painful process of East Asian countries being opened up to trade and outside influences in the 19th century, a process sometimes urged upon them by naval weapons in this era of gunboat diplomacy. This provides the setting for the Port Hamilton Affair itself when in preparation for possible war with Russia, a British naval squadron steamed into Port Hamilton and took it without reference to the local people or their national government. After brief reference to the political consequences of this action, the focus is then on what the records from the occupation and earlier investigations by the British, who had long coveted the islands’ strategic harbour, reveal about the life of the islanders. The article considers both their traditional life, from a time rather before western travel accounts were written about the Korean mainland, and how the islanders fared under the British.

    Full Text Available The quarantine pest tobacco whitefly Bemisia tabaci (Gennadius, 1889 was for the first time found in Croatia in 2000 on some culture and weed plants in greenhouses and in the open field in the area from Trogir to Omiš. Monitoring of tobacco whitefly was organized in all counties (21. Eventual presence of tobacco whitefly adults on the plants in glasshouses was established by the hanging of yellow sticky traps. In the course of monitoring the undersides of leaves on host plants were inspected for the purpose of discovering pest nymphal and pupal stages. The plants of poinsettia (Euphorbia pulcherrima produced as pest free plants have been used as catch plants in the conditions of lower infestation of host plants by tobacco whitefly adults. In three-year monitoring it was found out that poinsettia is the most atractive host plant for this pest between 38 host plants being registered during this monitoring. The fact that tobacco whitefly during the summer was found on the vegetables, ornamentals and weeds in the open fields in Dalmatia indicate that tobacco whitefly became domesticated and it can successfully overwinter in mediteranean climate conditions. During the monitoring tobacco whitefly was detected in 13 counties in our country, indicating shows that tobacco whitefly has been spreading progresivly since it was found in Croatia for the first time.

  1. Massive Open Online Courses for Africa by Africa

    Full Text Available Africa is known for inadequate access to all sorts of human needs including health, education, food, shelter, transport, security, and energy. Before the emergence of massive open online courses (MOOCs, open access to higher education (HE was exclusive of Africa. However, as a generally affordable method of post-secondary education delivery, MOOCs place the developing countries at the centre of universal access to HE. This paper provides the strategy for MOOC implementation in the context of limited resources in Africa. The strategy is clustered under five baseline requirements: national accredited MOOC curriculum, electronic content development, development of an online and offline eLearning platform, establishment and funding of MOOC coordination units at public HEIs, and establishment of MOOC access hubs at strategic locations. Emerging from this paper is the insight that a new era of universal access to HE in Africa is achievable through MOOCs only if initial requirements are met by the respective governments.

    This paper reports that South Africa's main reason for entering the international nuclear market is, and always has been, to sell its uranium abroad. From 1939-45 South Africa took part in the war against Nazi Germany, and the South African government of the time sought to help the Allied war effort in all ways that were practical. Later, during the Cold War, it tried to help build up the West's nuclear arsenal. In 1944, the British government secretly asked General Smuts---prime minister of South Africa since 1939 and a member of Churchill's War Cabinet---to survey South Africa's deposits of uranium. The survey, carried out with U.S. and British help, showed that the deposits were large, generally low-grade, but, in most cases, associated with gold and therefore could be profitably mined. In 1951, South Africa became a significant producer, with lucrative contracts for the sale of all its output to the U.S.-U.K.-Canada Joint Development Agency and one of the three main suppliers to the U.S. nuclear weapons program. In time, government controls eased and uranium production and marketing became a purely commercial operation

    Energy and economic growth are connected and the wealth of Western countries is based on a high availability of energy. Africa is a continent vast by its size, well populated and well supplied with fossil energy (oil, gas, coal) and renewable energy (hydroelectric, biomass, solar). But consumption is limited, without distribution infrastructures and initially, without capitals for necessary investments. The situation is particularly critical in Sub-Sahara Africa since the African energy consumption is mainly concentrated in South Africa and North Africa. An annual conference, the Energy Summit in Africa, brings together all players in the sector, from all the continent's countries, from Europe and America, in an attempt to establish recommendations for more availability and a better use of energy in Africa. The next summit is scheduled for November 23 to 25, 2004 in Dakar. The program relies on the Association for the Development of Energy in Africa, which will be created shortly. (author)

    This true-color image of South Africa was acquired on May 14, 2000, by NASA's Moderate-resolution Imaging Spectroradiometer, or MODIS. The image was produced using a combination of the sensor's 250-m and 500-m resolution visible wavelength bands. As part of the opening ceremony to begin the joint U.S.-South Africa SAFARI Field Experiment, NASA presented print copies of this image as GIFts to Dr. Ben Ngubane, Minister of Arts, Science and Technology, and Honorable Advocate Ngoaka Ramathlodi, Premier of the Northern Province, South Africa. The area shown in this image encompasses seven capital cities and a number of the region's distinctive geological features can be seen clearly. Toward the northern (top) central part of the image, the browns and tans comprise the Kalahari Desert of southern Botswana. The Tropic of Capricorn runs right through the heart of the Kalahari and the Botswanan capital city of Gaborone sits on the Limpopo River, southeast of the Kalahari. Along the western coastline of the continent is the country of Namibia, where the Namib Desert is framed against the sea by the Kaokoveld Mountains. The Namibian capital of Windhoek is obscured by clouds. Looking closely in the center of the image, the Orange River can be seen running from east to west, demarcating the boundary between Namibia and South Africa. On the southwestern corner of the continent is the hook-like Cape of Good Hope peninsula and Cape Town, the parliamentary capital of South Africa. Running west to east away from Cape Town are the Great Karroo Mountains. The shadow in this image conveys a sense of the very steep grade of the cliffs along the southern coast of South Africa. Port Elizabeth sits on the southeasternmost point of South Africa, and a large phytoplankton bloom can be seen in the water about 100 miles east of there. Moving northward along the east coast, the Drakensberg Mountains are visible. The two small nations of Lesotho and Swaziland are in this region, completely

  5. Redescription of the poorly known planktonic copepod Pontellopsis lubbockii (Giesbrecht, 1889) (Pontellidae) from the Eastern Tropical Pacific with a key to species

    Abstract During a survey of the epipelagic zooplankton carried out off the coast of the Mexican states of Jalisco and Colima, in the Eastern Tropical Pacific, female and male specimens of the poorly known calanoid copepod Pontellopsis lubbockii (Giesbrecht, 1889) were collected. Because previous descriptions and illustrations are largely incomplete and have caused some taxonomical confusion, this species is fully redescribed from specimens from the Mexican Pacific. The species has some characters that have been overlooked, but those related to the female genital double-somite are the most striking, it has two conical dorsal protuberances and a long ventral spiniform process unique of this species. The mouthparts of this species have not been hitherto described and figured, the flexible terminal setae of legs 3 and 4 is noteworthy. The male general morphology agrees in general with previous data, but new details of the leg 5 and geniculate antennule are added. Its mouthparts, with strong, serrate setae on the maxillae and maxillules, and a strong mandibular edge, suggest that this is a predator form. A dichotomous key for the identification of males and females of the species of Pontellopsis known from the Eastern Tropical Pacific is included. PMID:23372406

    The molecular pathogenesis of thymomas and thymic carcinomas (TCs) is poorly understood and results of adjuvant therapy are unsatisfactory in case of metastatic disease and tumor recurrence. For these clinical settings, novel therapeutic strategies are urgently needed. Recently, limited sequencing efforts revealed that a broad spectrum of genes that play key roles in various common cancers are rarely affected in thymomas and TCs, suggesting that other oncogenic principles might be important. This made us re-analyze historic expression data obtained in a spectrum of thymomas and thymic squamous cell carcinomas (TSCCs) with a custom-made cDNA microarray. By cluster analysis, different anti-apoptotic signatures were detected in type B3 thymoma and TSCC, including overexpression of BIRC3 in TSCCs. This was confirmed by qRT-PCR in the original and an independent validation set of tumors. In contrast to several other cancer cell lines, the BIRC3-positive TSCC cell line, 1889c showed spontaneous apoptosis after BIRC3 knock-down. Targeting apoptosis genes is worth testing as therapeutic principle in TSCC.

    Among the ancestral characteristics of the primate group to which Homo sapiens belongs we find a pattern of daytime physical activity, but one notable exception is birthing which usually begins with night-time labor. In populations with a moderate or high level of medicalized labor, there is evidence that the medical preferences interfere with the underlying biological mechanism for the circadian pattern of human birth. This study analyses the hourly patterns of 4,599 single live births in the House of Maternity in Madrid between 1887 and 1892, a period of very limited obstetric intervention and without the influence of artificial lighting. In order to determine the influence of natural light on labor, two periods of maximum and minimum light have been established around the summer and winter solstices of the years in question. A clear circadian pattern of births emerges, with very early morning and early morning births dominating, and a sharp drop from midday until nightfall. The hourly distribution on both solstices follows this pattern, but with a clear peak shift: in winter, there is a greater concentration of deliveries in the early morning, whereas in the summer, the highest concentration is between 8 and 12 in the morning. The results confirm that non-intervened human birth has a clear diurnal cycle, with a higher incidence of deliveries in the early morning or morning. The shift in distribution during the winter and summer solstices seems to confirm the effect of light on the labor process. © 2014 Wiley Periodicals, Inc.

    African tick-bite fever, caused by Rickettsia africae and transmitted by Amblyomma ticks, is an emerging rickettsiosis in southern Africa. Because of increased tourism to this area, several cases in tourists have been reported recently. We report 13 cases of R. africae infection diagnosed in France that occurred in competitors returning from an adventure race in South Africa and compare our data with previously reported findings. Most of our patients presented with fever, headache, multiple inoculation eschars, and regional lymphadenopathies, but only 15.4% had a cutaneous rash. Diagnosis was confirmed either by isolation of R. africae from an eschar biopsy specimen or by serological methods, including cross-adsorption between R. africae and Rickettsia conorii. The purpose of this study was to raise physicians' awareness of R. africae infections in an attempt to facilitate the rapid diagnosis and treatment of imported African tick-bite fever in developed countries.

    2016-12-01

    Full Text Available This article is dedicated to the development of the higher education in Sub-Saharan countries, particularly to the topic of internationalization of education. Most African countries have underdeveloped education systems. The quality and availability of higher education is a formidable obstacle for economic and social development. There is a growing demand for higher education in the SSA, but national education systems can’t cope fully with it. Hence many students go abroad, mostly in other African countries. The article focuses on the position of South Africa in the global and regional education market. As it’s a regional leader in this field South Africa attracts more than a half of international students within the Sub-Saharan Africa. The main reasons why African students choose South Africa are geographic proximity, familiar culture, lack of wanted higher education programs in their countries. However, there are as well disadvantages like xenophobia and race discrimination. South Africa has become a leader in Africa in the field of higher education, but it plays still small part at a global scale.

  15. Four concepts of Africa

    Directory of Open Access Journals (Sweden)

    Willem Fourie

    2015-05-01

    Full Text Available What makes the words ‘Africa’ and ‘African’ possible and useful? In this article it is argued that at least four internally coherent concepts of Africa exist, and that none of these concepts are ethically neutral. The article is presented as a contribution to attempts at using the term ‘Africa’ in self-critical, reflexive and constructive ways. It could therefore be of interest to all researchers, particularly those in the humanities and theology, who locate their research within the context of ‘Africa’. It is argued that Africa can be conceived of as a place, a commodity, a condition and an ideal. By drawing on mostly primary sources it is shown that the term ‘Africa’ only relatively recently came to refer to a continent, that Africa as a place and Africa as a condition in need of betterment formed the foundation for its commodification, and that Africa only very recently became a self-description of the people who live on the continent of Africa. Each of these concepts of Africa is shown to be based on a particular logic with both strengths and weaknesses.

    The molecular pathogenesis of thymomas and thymic carcinomas (TCs) is poorly understood and results of adjuvant therapy are unsatisfactory in case of metastatic disease and tumor recurrence. For these clinical settings, novel therapeutic strategies are urgently needed. Recently, limited sequencing efforts revealed that a broad spectrum of genes that play key roles in various common cancers are rarely affected in thymomas and TCs, suggesting that other oncogenic principles might be important. This made us re-analyze historic expression data obtained in a spectrum of thymomas and thymic squamous cell carcinomas (TSCCs) with a custom-made cDNA microarray. By cluster analysis, different anti-apoptotic signatures were detected in type B3 thymoma and TSCC, including overexpression of BIRC3 in TSCCs. This was confirmed by qRT-PCR in the original and an independent validation set of tumors. In contrast to several other cancer cell lines, the BIRC3-positive TSCC cell line, 1889c showed spontaneous apoptosis after BIRC3 knock-down. Targeting apoptosis genes is worth testing as therapeutic principle in TSCC. PMID:24427739

    Full Text Available Founded in Brazilian imperial period, Casa Boris had an important commercial role in the Northeast region of Brazil. Using a competitive business structure, it linked the Ceará Province (branch with France (headquarters, by importing manufactured goods and exporting raw materials. In this paper, we studied the Journal and Ledger of Casa Boris, particularly from 1872 to 1887. The study aimed to analyze the contents of the accounting records contained in these books so as to report facts and points of historical interest to the Brazilian Accounting. The main contribution of the research, in general, is associated with an attempt to understand the influence of political, economic, social and institutional settings on accounting practices and vice-versa. Our findings led to the conclusion that the bookkeeping of Casa Boris was transparent to reveal the quality of accounting control of commercial operations undertaken by the firm and also shows the coexistence of a incipient provincial market that concomitantly linked Brazil to Europe in the second period of Brazilian Monarchical Empire.

    2014-07-01

    Salvia is the largest genus in Lamiaceae and it has recently been found to be non-monophyletic. Molecular data on Old World Salvia are largely lacking. In this study, we present data concerning Salvia in Africa. The focus is on the colonization of the continent, character evolution and the switch of pollination systems in the genus. Maximum likelihood and Bayesian inference were used for phylogenetic reconstruction. Analyses were based on two nuclear markers [internal transcribed spacer (ITS) and external transcribed spacer (ETS)] and one plastid marker (rpl32-trnL). Sequence data were generated for 41 of the 62 African taxa (66 %). Mesquite was used to reconstruct ancestral character states for distribution, life form, calyx shape, stamen type and pollination syndrome. Salvia in Africa is non-monophyletic. Each of the five major regions in Africa, except Madagascar, was colonized at least twice, and floristic links between North African, south-west Asian and European species are strongly supported. The large radiation in Sub-Saharan Africa (23 species) can be traced back to dispersal from North Africa via East Africa to the Cape Region. Adaptation to bird pollination in southern Africa and Madagascar reflects parallel evolution. The phenotypic diversity in African Salvia is associated with repeated introductions to the continent. Many important evolutionary processes, such as colonization, adaptation, parallelism and character transformation, are reflected in this comparatively small group. The data presented in this study can help to understand the evolution of Salvia sensu lato and other large genera. © The Author 2014.

    Burley, Thomas E.

    2011-01-01

    The U.S. Geological Survey, in cooperation with the New Mexico Interstate Stream Commission, developed a geodatabase compendium (hereinafter referred to as the 'geodatabase') of available water-resources data for the reach of the Rio Grande from Rio Arriba-Sandoval County line, New Mexico, to Presidio, Texas. Since 1889, a wealth of water-resources data has been collected in the Rio Grande Basin from Rio Arriba-Sandoval County line, New Mexico, to Presidio, Texas, for a variety of purposes. Collecting agencies, researchers, and organizations have included the U.S. Geological Survey, Bureau of Reclamation, International Boundary and Water Commission, State agencies, irrigation districts, municipal water utilities, universities, and other entities. About 1,750 data records were recently (2010) evaluated to enhance their usability by compiling them into a single geospatial relational database (geodatabase). This report is intended as a user's manual and administration guide for the geodatabase. All data available, including water quality, water level, and discharge data (both instantaneous and daily) from January 1, 1889, through December 17, 2009, were compiled for the study area. A flexible and efficient geodatabase design was used, enhancing the ability of the geodatabase to handle data from diverse sources and helping to ensure sustainability of the geodatabase with long-term maintenance. Geodatabase tables include daily data values, site locations and information, sample event information, and parameters, as well as data sources and collecting agencies. The end products of this effort are a comprehensive water-resources geodatabase that enables the visualization of primary sampling sites for surface discharges, groundwater elevations, and water-quality and associated data for the study area. In addition, repeatable data processing scripts, Structured Query Language queries for loading prepared data sources, and a detailed process for refreshing all data in the

  7. Decolonizing Bioethics in Africa.

    Science.gov (United States)

    Fayemi, Ademola Kazeem; Macaulay-Adeyelure, O C

    2016-01-01

    The global spread of bioethics from its North-American and European provenance to non-Western societies is currently raising some concerns. Part of the concern has to do with whether or not the exportation of bioethics in its full Western sense to developing non-Western states is an instance of ethical imperialism or bioethical neocolonialism. This paper attempts an exploration of this debate in the context of bioethics in sub-Saharan Africa. Rather than conceding that bioethics has a colonial agenda in Africa, this paper defends the position that the current bioethics trend in sub-Saharan Africa is an unintended imperialistic project. It argues that its colonizing character is not entirely a product of the Western programmed goals of training and institution building; rather, it is a structural consequence of many receptive African minds and institutions. Though bioethics in Africa is turning out as a colonizing project, one serious implication of such trend, if unchecked urgently, is that bioethics' invaluable relevance to Africa is being incapacitated. This paper, therefore, attempts a decolonizing trajectory of bioethics in Africa. Contrary to the pretense of 'African bioethics,' which some African scholars are now defending, this paper through the logic of decolonization makes case for 'bioethics in Africa'. In such logic, the principle of existential needs is prioritized over the principle of identity and authenticity that define African voice in bioethics.

    2015-01-01

    The vision for astronomy in Africa is embedded in the African Space Policy of the African Union in early 2014. The vision is about positioning Africa as an emerging hub for astronomy sciences and facilities. Africa recognized the need to take advantage of its natural resource, the geographical advantage of the clear southern skies and pristine sites for astronomy. The Pan African University (PAU) initiative also presents an opportunity as a post-graduate training and research network of university nodes in five regions of Africa and supported by the African Union. The Southern African node based in South Africa concentrates on space sciences which also includes astronomy. The PAU aims to provide the opportunity for advanced graduate training and postgraduate research to high-performing African students. Objectives also include promoting mobility of students and teachers and harmonizing programs and degrees.A number of astronomy initiatives have burgeoned in the Southern African region and these include the Southern Africa Largest Optical Telescope (SALT), HESS (High Energy Stereoscopic System), the SKA (Square Kilometre Array) and the AVN (African Very Long Baseline Interferometer Network). There is a growing appetite for astronomy sciences in Africa. In East Africa, the astronomy community is well organized and is growing - the East African Astronomical society (EAAS) held its successful fourth annual conference since 2010 on 30 June to 04 July 2014 at the University of Rwanda. Centred around the 'Role of Astronomy in Socio-Economic Transformation,' this conference aimed at strengthening capacity building in Astronomy, Astrophysics and Space Science in general, while providing a forum for astronomers from the region to train young and upcoming scientists.

It exploresthe countries’ political and economic interests in Africa, the various patterns and strategies of each country’s cooperationwith Africa, and estimates the impact of BRICS aid and investment on the African economy and Africa’s development. TheBRICS countries have emerged as the new effective actors in the world arena. Their global economic weight and politicalinfluence continue to grow. Not only is the group focusing its attention on strengthening the internal ties of its members, but itis also focusing on assistance to Africa, as a way to implement the emerging powers efforts to change the existing world order.The BRICS is deepening its engagement with African countries, which gained great success in their development in recentyears. Its focus on Africa is determined by the important role of African resources and by the continent’s growing influencein the world economy and contemporary international relations. BRICS countries are major trade partners of Africa, andAfrica’s trade with BRICS members is growing faster than its trade with the traditional partners. Africa has become themain destination for BRICS development aid and investment. The BRICS is also focusing on African infrastructure. BRICScountries use soft power widely, through developing humanitarian ties with Africa, particularly in health care and education.The BRICS is also an active participant in peacekeeping and conflict resolution in Africa. Members currently tend tocompete in Africa, but they are taking steps toward collaboration. The BRICS contributes much to the African economy. Itspresence has become important for the continent and receives a positive response there.

    Full Text Available In the present article author explores the history and legal framework for the creation and operation of international commercial arbitration in South Africa. Author notes that South Africa is the most economically developed country in Africa, it is among dozens of major international organizations. From the point of view of the development of the system of law, legal proceedings and arbitration, South Africa is an attractive state for study. Author emphasizes that the South African Republic throughout its existence has been influenced by two legal families: Anglo-Saxon and Romano-Germanic. Therefore, it is important to note that South Africa refers to a mixed system of law. To date, South Africa has two international commercial arbitration: the Arbitration Foundation of South Africa and the Association of Arbitrators. In the conclusion author points out that the development and establishment of the centers of the arbitration fund continues: new centers are being established, and the system of procedures for dealing with cases in already established centers is being improved.

  12. Unprecedented emergency in Southern Africa.

    Science.gov (United States)

    1999-03-01

    Despite knowledge of better prevention strategies, AIDS continues to be an unprecedented emergency in southern Africa. Statistics show that in 1998, 1.4 million people between the ages of 15 and 49 in the 9 countries of southern Africa were infected, with nearly three-quarters of a million of these new infections occurring in South Africa. In addition, some 2 million people died of AIDS in sub-Saharan Africa in 1998 and millions of new infections are occurring every year. Factors such as the loneliness suffered by migrant laborers, the wars and armed conflicts in Rwanda, and the stigma of shame, silence, and denial associated with AIDS all generate fertile conditions for the spread of HIV in southern Africa. Overcoming silence and denial, and bringing AIDS out into the open, has been considered by some countries in southern Africa. In Botswana and South Africa, appeals for greater awareness and openness by the top leadership have been coupled with a decision to set up government funding and AIDS. The challenge now will be to translate these into effective prevention and care programs.

    This paper summarizes the progress in the search for hantaviruses and hantavirus infections in Africa. After having collected molecular evidence of an indigenous African hantavirus in 2006, an intensive investigation for new hantaviruses has been started in small mammals. Various novel hantaviruses have been molecularly identified not only in rodents but also in shrews and bats. In addition, the first African hantavirus, Sangassou virus, has been isolated and functionally characterized in cell culture. Less is known about the ability of these hantaviruses to infect humans and to cause diseases. To date, no hantavirus genetic material could be amplified from patients' specimens collected in Africa. Serological studies in West Africa, based on a battery of screening and confirmatory assays, led to the detection of hantavirus antibodies in the human population and in patients with putative hantavirus disease. In addition to this overview, we present original data from seroepidemiological and field studies conducted in the Southern part of Africa. A human seroprevalence rate of 1.0% (n=1442) was detected in the South African Cape Region whereas no molecular evidence for the presence of hantavirus was found in 2500 small animals trapped in South Africa and Namibia.

  9. Africa: signs of hope?

    Directory of Open Access Journals (Sweden)

    J.F. Kirsten

    2008-07-01

    Full Text Available The dawning of the 21st century generally brought new hope to African leaders and countless thousands of ordinary citizens of many countries on the continent. The first signs of a new turn of events shone through by the end of the last decade of the previous century. This was manifested by economic growth rates that started to pick up in a number of African states, by pro-democracy movements which in country after country succeeded in replacing authoritarian regimes, and by the winding down and termination of some of Africa’s most devastating wars. The results of this analysis confirm the above-mentioned positive political, economic and conflict trends in Africa. It is clearly a significant turn of events given the well-known political and economic predicament with which Africa is struggling. When this negative legacy and Cold War background of Africa is considered, the importance of present developments is clear to see. The identified heightened sense of purpose among the leaders and peoples of Africa and the changed mood and need among Africans to take charge of their own future that found expression in the New Partnership for Africa’s Development (NEPAD are indeed significant and bode well for the future of the continent. A word of warning here is, however, necessary. Our conduct with Africa must be very cautious and we must guard against over-optimism and the exaggerated belief that Africa is now on a trajectory of sustained development and peace. We cannot generalise about Africa – for that the continent is just too big and diverse from a geographical, cultural, economic and political point of view.

    In the early 1980s, the Republic of South Africa was the world's second-largest producer of uranium, and the country historically has been a major exporter of many other important mineral resources, including gold, platinum group metals, manganese, vanadium, and gem-quality diamonds. Yet political turbulence in the latter part of the decade caused economic stress on South Africa. Apartheid, the country's disenfranchisement of the black majority, put South Africa in the international spotlight. The world responded by implementing economic sanctions against South Africa, to pressure its government into change. In the past several years, South Africa has made significant progress toward ending apartheid. As a result, many US economic sanctions previously maintained against the country have been lifted. However, economic troubles continue to plague South Africa; repealing sanctions has done little to alleviate its economic and political challenges

    The South African Astronomical Observatory (SAAO) observing station near Sutherland, Northern Cape in South Africa, is one of the darkest sites in the world for optical and IR astronomy. The SAAO hosts and operates several facilities, including the Southern African Large Telescope (SALT) and a number of international robotic telescopes. To ensure that the conditions remain optimal for astronomy, legislation called the Astronomy Geographic Advantage (AGA) Act, of 2007, was enacted. The Act empowers the Department of Science and Technology (DST) to regulate issues that pose a threat to optical and/or radio astronomy in areas declared Astronomy Advantage Areas in South Africa. For optical astronomy, the main challenges are those posed by light and dust pollution as result of wind energy developments, and petroleum gas and oil exploration/exploitation in the area. We give an update of possible threats to the quality of the night skies at SAAO, and the challenges relating to the AGA Act implementation and enforcement. We discuss measures that are put in place to protect the Observatory, including a study to quantify the threat by a planned wind energy facility.

  16. [Matrimonial changes in Africa].

    1997-01-01

    A database of census and survey information on fertility and nuptiality in Africa being assembled by the French Center for Population and Development (CEPED) was the source for this analysis of changing marriage patterns. Early marriage for girls, nearly universal marriage for both sexes, rapid remarriage of reproductive-age widows and divorcees, polygamy, and a frequently large difference in the ages of the spouses are typical of African marriage. But a great variety of situations coexist. In the 1960s, the female age at first marriage was under 17.5 years on average in West Africa, while the male age was over 26. Nearly everyone married, and one-fourth to one-third of married men were polygamous. In South Africa, at the other extreme, the average age at first marriage was 20-23 for women and 26-30 for men, over 5% never married, and polygamy was rare. Nuptiality patterns were intermediate in North, Central, and East Africa. The most recent round of censuses and surveys show the geographic differences to be shrinking. Average age at first marriage for women is increasing everywhere and often exceeds 19 years. It remains lower than 17.5 in only two countries. The increase amounts to at least a half year for 30 countries and over 1 year for 15. Marriage remains nearly universal except in South Africa. Male age at marriage is rising more slowly than female age, causing the average age gap to decline. Economic difficulties and unemployment appear to play a significant role in the delay of marriage, with increased female school attendance also a factor, although secondary and higher education for females in sub-Saharan Africa is too uncommon to have perceptible effects on the national scale. In North Africa, the age at first birth has increased in tandem with increasing marriage age, but in sub-Saharan Africa the relationship has been less marked. In Lome, for example, the increasing age at first marriage for females has had no effect on age at first birth. The

  18. The balance of trade in alien species between South Africa and the rest of Africa

    Directory of Open Access Journals (Sweden)

    Katelyn T. Faulkner

    2017-03-01

    Full Text Available Background: Alien organisms are not only introduced from one biogeographical region to another but also spread within regions. As South Africa shares land borders with six countries, multiple opportunities exist for the transfer of alien species between South Africa and other African countries; however, the direction and importance of intra-regional spread is unclear. Objectives: The aim of this study was to gain a greater understanding of the introduction of alien species into Africa and the spread of species between South Africa and other African countries. Method: We developed scenarios that describe the routes by which alien species are introduced to and spread within Africa and present case studies for each. Using data from literature sources and databases, the relative importance of each scenario for alien birds and insect pests of eucalypts was determined, and the direction and importance of intra-regional spread was assessed. Results: Alien species from many taxonomic groups have, through various routes, been introduced to and spread within Africa. For birds and eucalypt insect pests, the number of species spreading in the region has recently increased, with South Africa being a major recipient of birds (14 species received and 5 donated and a major donor of eucalypt insect pests (1 species received and 10 donated. For both groups, many introduced species have not yet spread in the region. Conclusion: The intra-regional spread of alien species in Africa represents an important and possibly increasing threat to biosecurity. To address this threat, we propose a framework that details how African countries could cooperate and develop a coordinated response to alien species introductions.

    Macharia, Daniel; Korme, Tesfaye; Policelli, Fritz; Irwin, Dan; Adler, Bob; Hong, Yang

    2010-01-01

    SERVIR-Africa is an ambitious regional visualization and monitoring system that integrates remotely sensed data with predictive models and field-based data to monitor ecological processes and respond to natural disasters. It aims addressing societal benefits including floods and turning data into actionable information for decision-makers. Floods are exogenous disasters that affect many parts of Africa, probably second only to drought in terms of social-economic losses. This paper looks at SERVIR-Africa's approach to floods disaster management through establishment of an integrated platform, floods prediction models, post-event flood mapping and monitoring as well as flood maps dissemination in support of flood disaster management.

  20. Uranium in a changing South Africa

    Energy Technology Data Exchange (ETDEWEB)

    1993-05-01

    In the early 1980s, the Republic of South Africa was the world's second-largest producer of uranium, and the country historically has been a major exporter of many other important mineral resources, including gold, platinum group metals, manganese, vanadium, and gem-quality diamonds. Yet political turbulence in the latter part of the decade caused economic stress on South Africa. Apartheid, the country's disenfranchisement of the black majority, put South Africa in the international spotlight. The world responded by implementing economic sanctions against South Africa, to pressure its government into change. In the past several years, South Africa has made significant progress toward ending apartheid. As a result, many US economic sanctions previously maintained against the country have been lifted. However, economic troubles continue to plague South Africa; repealing sanctions has done little to alleviate its economic and political challenges.

  1. Poverty reduction in Africa.

    Collier, Paul

    2007-10-23

    Poverty in Africa has been rising for the last quarter-century, while it has been falling in the rest of the developing world. Africa's distinctive problem is that its economies have not been growing. This article attempts to synthesize a range of recent research to account for this failure of the growth process. I argue that the reasons lie not in African peculiarities but rather in geographic features that globally cause problems but that are disproportionately pronounced in Africa. These features interact to create three distinct challenges that are likely to require international interventions beyond the conventional reliance on aid.

  3. Dam-Breach hydrology of the Johnstown flood of 1889-challenging the findings of the 1891 investigation report.

    2016-06-01

    In 1891 a report was published by an ASCE committee to investigate the cause of the Johnstown flood of 1889. They concluded that changes made to the dam by the South Fork Fishing and Hunting Club did not cause the disaster because the embankment would have been overflowed and breached if the changes were not made. We dispute that conclusion based on hydraulic analyses of the dam as originally built, estimates of the time of concentration and time to peak for the South Fork drainage basin, and reported conditions at the dam and in the watershed. We present a LiDAR-based volume of Lake Conemaugh at the time of dam failure (1.455 × 10(7) m(3)) and hydrographs of flood discharge and lake stage decline. Our analytical approach incorporates the complex shape of this dam breach. More than 65 min would have been needed to drain most of the lake, not the 45 min cited by most sources. Peak flood discharges were likely in the range 7200 to 8970 m(3) s(-1). The original dam design, with a crest ∼0.9 m higher and the added capacity of an auxiliary spillway and five discharge pipes, had a discharge capacity at overtopping more than twice that of the reconstructed dam. A properly rebuilt dam would not have overtopped and would likely have survived the runoff event, thereby saving thousands of lives. We believe the ASCE report represented state-of-the-art for 1891. However, the report contains discrepancies and lapses in key observations, and relied on excessive reservoir inflow estimates. The confidence they expressed that dam failure was inevitable was inconsistent with information available to the committee. Hydrodynamic erosion was a likely culprit in the 1862 dam failure that seriously damaged the embankment. The Club's substandard repair of this earlier breach sowed the seeds of its eventual destruction.

    Gilgado, José D; Ortuño, Vicente M

    2015-02-19

    New locations of Coletinia maggii (Grassi, 1887) have been discovered in the center of the Iberian Peninsula in different types of subterranean environments, such as a stony layer in the subsoil of an alluvial plain, an alluvial Mesovoid Shallow Substratum or Milieu Souterrain Superficiel (MSS) and a gypsum cave. This is the first record of both an alluvial MSS in the center of the Iberian Peninsula and of a subterranean species living in it. The high number of specimens captured allowed the first detailed study of the morphological intra- and inter-population variations of this species. The implications of its presence in these different environments, its wide distribution area across Europe, and the relevance of the morphological variation in the characters for the taxonomy of this species are discussed. Based on the results, Coletinia hernandoi Molero, Bach & Gaju, 2013 is proposed as a new synonym of C. maggii.

  10. Africa's middle class women bring entrepreneurial opportunities in breast care medical tourism to South Africa.

    Ahwireng-Obeng, Frederick; van Loggerenberg, Charl

    2011-01-01

    Africa's distribution of specialized private health services is severely disproportionate. Mismatch between South Africa's excess supply and a huge demand potential in an under-serviced continent represents an entrepreneurial opportunity to attract patients to South Africa for treatment and recuperative holidays. However, effective demand for intra-African medical tourism could be constrained by sub-Saharan poverty. Results from interviewing 320 patients and five staff at the Johannesburg Breast care Centre of Excellence, however, reject this proposition, Africa's middle class women being the target market estimated to grow annually by one million while breast cancer incidence increases with middle-class lifestyles. Uncovering this potential involves an extensive marketing strategy. Copyright © 2010 John Wiley & Sons, Ltd.

    2004-07-01

    The influence of heating over Africa on the South American precipitation climatology, and the influence of South America on Africa, is examined through the application of GCM simulations with idealized boundary conditions and perpetual solstice (January and July) conditions.The presence of Africa is associated with a pronounced (up to 4 mm day-1) decrease in precipitation in Brazil's Nordeste region during austral summer. Low-level moisture divergence and dry-air advection associated with the downbranch of a Walker circulation induced by heating over southern Africa is amplified over the Nordeste due to the response of the land surface. The response is much smaller during austral winter due to differences in the heat source over Africa and a reduced sensitivity in the surface heat balance over tropical South America. Forcing from South America in January shifts the position of the South Indian convergence zone (SICZ) to the southwest over southern Africa in association with the formation of the South Atlantic convergence zone (SACZ). In July, a Rossby wave train generated over South America induces a response in the surface temperature of Africa that leads to stronger precipitation in central and western Africa.This study suggests a zonal mode of variability for South American and African circulation and precipitation fields. The resulting perturbations depend as much on land surface atmosphere interactions as on the direct forcing from the adjacent continent, and the mechanisms are highly nonlinear.

    2012-01-01

    Full Text Available Partindo da análise de documentação consultada em arquivos do Brasil e do Vaticano, o artigo discute as relações entre Estado e Igreja Católica Apostólica Romana (ICAR no período da Primeira República brasileira. Considera-se que a Proclamação da República em 15 de novembro de 1889 foi associada, por algumas parcelas das elites brasileiras da época, ao ideário do progresso e da civilização, sendo uma de suas primeiras tarefas a extinção do padroado em 7 de janeiro de 1890. O laicismo determinado nessa ocasião pelo Decreto 119-A revelou-se, entretanto, ambíguo e pragmático. Livre das amarras constitucionais do padroado, o Estado criou um novo campo de relações com as diferentes confissões religiosas, segundo os seus próprios interesses institucionais. Nesse contexto, a ICAR, por sua vez, empreendeu um processo de reforma e reorganização eclesiástica cujo fulcro consistiu na criação de dioceses e jurisdições similares - um amplo e complexo processo territorial, político e discursivo ao qual se pode denominar diocesanização.

    2010-03-01

    Full Text Available In the context of globalisation and the current global financial crisis, new players are emerging in cooperation in Africa. These partners loosen financial constraints and conditionalities, increase the room for manoeuvre and stimulate commodity markets. On the other hand, they also increase the risks of renewed indebtedness and potentially weaken the coordination of aid policies. Do these partnerships call the new cooperation practices of OECD countries into question? Do they justify the return to a realpolitik or are they repeating the earlier mistakes of industrial powers? Can these mistakes be corrected? The question also arises as to whether the global crisis, which has a profound effect on Africa, will lead to a withdrawal or to a passing of the baton on to new, emerging powers. This article highlights the new geopolitical issues concerning Africa in a multipolar world, then discusses the new players involved in cooperation in Africa, before going on to explore the horizons that are opening up for cooperation in Africa, in particular with regard to the global crisis.

    1994-01-01

    Over 185 million inhabitants were added to the urban areas of Africa between 1950 and 1990. Botswana, Lesotho, Namibia, South Africa, and Swaziland is the most highly urbanized, with 55% in 1990; while less than a quarter of Eastern Africa's population is living in urban centers. By the year 2015 more than half of Africa's population will be living in urban areas. Many parts of Africa have suffered prolonged droughts, overgrazing, locust infestations, and desertification. Millions have become refugees from natural disasters, political oppression, and rural poverty. The large exodus from Africa's rural areas has gone to cities but the large cities have attracted disproportionately large numbers of destitute migrants. Alexandria (1 million), Cairo (2.4 million) and the Witwatersrand in South Africa were the only African urban agglomerations with at least one million inhabitants in 1950. By 1990 the two Egyptian cities together had 12.7 million inhabitants and the Witwatersrand some 5 million, whereas the other 25 urban agglomerations with a million inhabitants each in 1990 had a total population of about 51 million. Lagos, Kinshasa, and Algiers ranged from 3 to 7.7 million. The capitals are the largest cities in at least 54 of the 59 countries and territories. Lagos, Nairobi, and Dar es Salaam are disproportionately larger than the next most populous cities in their countries. The 28 urban agglomerations with at least one million inhabitants had a total population of 70 million in 1990, and are projected to reach 100 million in the year 2000. Overall, Africa's urban population is projected to increase by approximately 135 million in the 1990-2000 decade (from 217 million to 352 million). About 105 million of the growth probably will occur in the smaller urban centers. The total African urban population is likely to reach one billion inhabitants within the next 50 years. It stood at 32 million in 1950. Presently, the United Nations projects 912 million urban residents

    Full Text Available Human immunodeficiency virus and the acquired immunodeficiency syndrome (HIV/AIDS have greatly complicated dermatologic disease and the required care in most regions of Africa. Opportunistic infections, ectoparasites, Kaposi sarcoma, and skin manifestations of systemic infections are exceedingly common in patients with HIV/AIDS. Dermatologists have contributed significantly to our knowledge base about HIV/AIDS and have played an important educational role regarding the clinical manifestations historically. Because of the increased burden of skin disease in Africa due to the HIV/AIDS epidemic we must redouble our efforts to provide dermatology education to care providers in Africa. We review the burden of skin disease in Africa, how it relates to HIV/AIDS and global infectious disease, current educational strategies in Africa to address this need, and suggest potential solutions to move these efforts forward.

    Full Text Available A qualitative and comparative study was carried out on some locally sourced oils melon oil Africa elemi oil and Africa locust bean oil to evaluate suitability as substitute quenching media to mineral-based oil. The cooling ability of the oils was investigated using AISI 1034 medium carbon steel. The effect of heat transfer coefficient on quench severity mechanical properties of the quenched specimens were investigated in the course of the study. Results showed that the peak rate of heat extraction of melon oil Africa locust bean and Africa elemi oil were higher than that of mineral oil. Higher heat transfer coefficient of 1463 1023 Wm2k were obtained for melon oil and Africa locust bean Africa elemi and SAE 40 oil have heat transfer coefficient of 982 and 469 Wm2k respectively. The selected oils can be used as quenchants for medium carbon steel since the oils exhibits better cooling properties and mechanical properties than mineral-based oil.

    2011-01-01

    This article first proposes an overview of the present situation of the electricity sector in Africa: the continent is an energy giant because of all the resources it possesses, but an electricity dwarf regarding its present and actual capacities. The author outlines the differences between potential and actual productions, gives an overview of the current status of supply and of production capacities. She comments the status of electricity demand, electricity consumption and electricity markets in the different parts of Africa (data of electricity consumption, of global, urban and rural electrification in Northern Africa, Western Africa, Central Africa, Eastern Africa, Southern Africa with or without South Africa), and issues related to costs and tariffs. She proposes some explanations for the observed discrepancies between African regions and countries: history, too small markets supported by too fragile economies, political and economic failures. Then, she discusses how to favour a durable development of the African electricity sector

    The Square Kilometre Array (SKA) Organisation announced in May 2012 that its members had agreed on a dual site solution for the SKA [1]. South Africa's bid for hosting the SKA has caused a ramp up of radio astronomy in Africa. To develop technology towards the SKA, the South African SKA Project (SKA SA) built a protoype radio telescope in 2007, followed in 2010 the seven antenna Karoo Array Telescope (KAT-7). Next is the 64 antenna MeerKAT, which will merge into SKA Phase 1 in Africa. As SKA Phase 2 is intended to add a high resolution capability with baselines out to 3000 km, the SKA SA brought in partner countries in Africa to host outstations. South Africa has been working with the partners to build capacity to operate the SKA and to benefit from it. The SA Department of Science and Technology (DST) developed a proposal to establish radio telescopes in the partner countries to provide hands-on learning and a capability for Very Long Baseline Interferometry (VLBI) research. Redundant 30 m class satellite antennas are being incorporated in this project.

    South Africa and the BRICS: A critical appraisal Michael Omondi Owiso and Johannes Dragsbaek Schmidt Abstract The objective of the BRICS was originally supposed to merge economic synergies and create an alternative voice in the global governance system. Debates around the ability of the BRICS...... to acquire this clout continue to dominate academia and the global discourse. Although the alliance is still in its nascent stage, scholarly attention is increasingly looking at its internal dynamics. The inclusion of South Africa being the smallest economy in the BRICS was indeed an effort to consolidate...... its image and unleash the developmental potential for the rest of the African continent. Comparably, South Africa is probably the least influential member of the BRICS, and this raises the following questions. First, how does South Africa´s affiliation impact on the development and benefits regarding...

    Africa is a home to around 800 million people. The total population is expected to reach 1.3 billion by 2020. Efficient, clean energy forms are vital to Africa's sustainable development and fight against poverty. Nuclear power is a sustainable, clean, safe and economic way to met the African countries demand for electrical energy and water desalination As of 29 January 2007, there were 435 nuclear power plants in operation around the world. They total about 369 G We of generating capacity and supply about 16% of the world electricity. Of the 435 nuclear power plants in operation, just two are in Africa: Koeberg-1 and Koeberg-2 in South Africa. Both are 900 M We PWRs.There are also 28 new nuclear power plants under construction none in Africa. In this paper, varies factors , which support the attractiveness of nuclear power for African countries are identified and discussed

    An ongoing question in paleoenvironmental reconstructions of the central African rainforest concerns the role that prehistoric metallurgy played in shaping forest vegetation. Here we report evidence of intensive iron-ore mining and smelting in forested regions of the northern Congo Basin dating to the late Holocene. Volumetric estimates on extracted iron-ore and associated slag mounds from prehistoric sites in the southern Central African Republic suggest large-scale iron production on par with other archaeological and historically-known iron fabrication areas. These data document the first evidence of intensive iron mining and production spanning approximately 90 years prior to colonial occupation (circa AD 1889) and during an interval of time that is poorly represented in the archaeological record. Additional site areas pre-dating these remains by 3-4 centuries reflect an earlier period of iron production on a smaller scale. Microbotanical evidence from a sediment core collected from an adjacent riparian trap shows a reduction in shade-demanding trees in concert with an increase in light-demanding species spanning the time interval associated with iron intensification. This shift occurs during the same time interval when many portions of the Central African witnessed forest transgressions associated with a return to moister and more humid conditions beginning 500-100 years ago. Although data presented here do not demonstrate that iron smelting activities caused widespread vegetation change in Central Africa, we argue that intense mining and smelting can have localized and potentially regional impacts on vegetation communities. These data further demonstrate the high value of pairing archeological and paleoenvironmental analyses to reconstruct regional-scale forest histories.

    Telemedicine includes the use of information and communication technology for education in the health sector, tele-education. Sub-Saharan Africa has an extreme shortage of health professionals and as a result, doctors to teach doctors and students. Tele-education has the potential to provide access to education both formal and continuing medical education. While the uptake of telemedicine in Africa is low, there are a number of successful and sustained tele-education programs. The aims of this study were (i) to review the literature on tele-education in South Africa, (ii) describe tele-education activities at the University of KwaZulu-Natal (UKZ-N) in South Africa, and (iii) review the development of these programs with respect to current thinking on eHealth project implementation. A literature review of tele-education in South Africa was undertaken. The development of the tele-education services at UKZ-N from 2001 to present is described. The approaches taken are compared with current teaching on eHealth implementation and a retrospective design-reality gap analysis is made. Tele-education has been in use in South Africa since the 1970s. Several forms of tele-education are in place at the medical schools and in some Provincial Departments of Health (DOH). Despite initial attempts by the National DOH, there are no national initiatives in tele-education. At UKZ-N, a tele-education service has been running since 2001 and appears to be sustainable and reaching maturity, with over 1,400 h of videoconferenced education offered per year. The service has expanded to offer videoconferenced education into Africa using different ways of delivering tele-education. Tele-education has been used in different forms for many years in the health sector in South Africa. There is little hard evidence of its educational merit or economic worth. What it apparent is that it improves access to education and training in resource constrained settings. The development of local and

    2015-01-01

    The Annals of Botany is a peer-reviewed scientific journal publishing papers on a wide range of topics in plant biology. It first appeared in 1887, making it the oldest continuously published botanical title. The present article gives a historical account of events leading to the founding of the Journal and of its development over the first 50 years. Much of the content is drawn from the Journal's own records and from extensive Minutes, financial accounts, personal letters and notes relating to the Annals of Botany that were repatriated from University College, University of London in 1999. Documents held at the Royal Botanic Gardens, Kew and at the Oxford University Press Museum were also consulted. Emphasis is placed on the individuals who instigated, edited and managed the Annals of Botany up to 1937, especially the nine founding members of the Journal and the background that brought them together and motivated them to start the Annals of Botany. A falling out between two of the founders in 1899 is highlighted since not only did this threaten the Journal's future but also gives much insight into the personalities of those most closely involved in the Journal during its formative years. The article also examines the way the Journal was funded and how it dealt with its publisher (the University of Oxford's Clarendon Press), turned itself into a registered company (the Annals of Botany Company) and coped with the travails of the First World War, currency inflation and the Great Depression. Plans to re-start the Journal as a New Series, beginning in 1937, are discussed in the context of the competition the Annals of Botany then faced from younger journals. © The Author 2014.

    The study of meteorites provides insight into the earliest history of our solar system. From 1800, about the year meteorites were first recognized as objects falling from the sky, until December 2014, 158 observed meteorite falls were recorded in Africa. Their collected mass ranges from 1.4 g to 175 kg with the 1-10 kg cases predominant. The average rate of African falls is low with only one fall recovery per 1.35-year time interval (or 0.023 per year per million km2). This African collection is dominated by ordinary chondrites (78%) just like in the worldwide falls. The seventeen achondrites include three Martian meteorite falls (Nakhla of Egypt, Tissint of Morocco and Zagami of Nigeria). Observed Iron meteorite falls are relatively rare and represent only 5%. The falls' rate in Africa is variable in time and in space. The number of falls continues to grow since 1860, 80% of which were recovered during the period between 1910 and 2014. Most of these documented meteorite falls have been recovered from North-Western Africa, Eastern Africa and Southern Africa. They are concentrated in countries which have a large surface area and a large population with a uniform distribution. Other factors are also favorable for observing and collecting meteorite falls across the African territory, such as: a genuine meteorite education, a semi-arid to arid climate (clear sky throughout the year most of the time), croplands or sparse grasslands and possible access to the fall location with a low percentage of forest cover and dense road network.

  8. Impacts of Climate Change on Malaria Transmission in Africa

    Science.gov (United States)

    Eltahir, E. A. B.; Endo, N.; Yamana, T. K.

    2017-12-01

    Malaria is a major vector-borne parasitic disease transmitted to humans by Anopheles spp mosquitoes. Africa is the hotspot for malaria transmission where more than 90% of malaria deaths occur every year. Malaria transmission is an intricate function of climatic factors, which non-linearly affect the development of vectors and parasites. We project that the risk of malaria will increase towards the end of the 21st century in east Africa, but decrease in west Africa. We combine a novel malaria transmission simulator, HYDREMATS, that has been developed based on comprehensive multi-year field surveys both in East Africa and West Africa, and the most reliable climate projections through regional dynamical downscaling and rigorous selection of GCMs from among CMIP5 models. We define a bell-shaped relation between malaria intensity and temperature, centered around a temperature of 30°C. Future risks of malaria are projected for two highly populated regions in Africa: the highlands in East Africa and the fringes of the desert in West Africa. In the highlands of East Africa, temperature is substantially colder than this optimal temperature; warmer future climate exacerbate malaria conditions. In the Sahel fringes in West Africa, temperature is around this optimal temperature; warming is not likely to exacerbate and might even reduce malaria burden. Unlike the highlands of East Africa, which receive significant amounts of annual rainfall, dry conditions also limit malaria transmission in the Sahel fringes in West Africa. This disproportionate risk of malaria due to climate change should guide strategies for climate adaptation over Africa.

    Modern energy access in Africa is critical to meeting a wide range of developmental challenges including poverty reduction and the Millennium Development Goals (MDGs). Despite having a huge amount and variety of energy resources, modern energy access in the continent is abysmal, especially Sub-Saharan Africa. Only about 31% of the Sub-Saharan African population have access to electricity while traditional biomass energy accounts for over 80% of energy consumption in many Sub-Saharan African countries. With energy use per capita among the lowest in the world, there is no doubt that Africa will need to increase its energy consumption to drive economic growth and human development. Africa also faces a severe threat from global climate change with vulnerabilities in several key areas or sectors in the continent including agriculture, water supply, energy, etc. Low carbon development provides opportunities for African countries to improve and expand access to modern energy services while also building low-emission and climate-resilient economies. However, access to finance from different sources will be critical in achieving these objectives. This paper sets out to explore the financial instruments available for low carbon energy access in Africa including the opportunities, markets and risks in low carbon energy investments in the continent. - Highlights: ► Access to finance will be critical to achieving low carbon energy access in Africa. ► Domestic finance will be important in leveraging private finance. ► Private sector participation in modern and clean energy in Africa is still low. ► Many financing mechanisms exist for low carbon energy access in Africa. ► The right institutional frameworks are critical to achieving low carbon energy access in Africa.

    CKD affects an estimated 14% of adults in sub-Saharan Africa, but very little research has been done on the cause, progression, and prevention of CKD there. As part of the Human Heredity and Health in Africa (H3Africa) Consortium, the H3Africa Kidney Disease Research Network was established to study prevalent forms of kidney disease in sub-Saharan Africa and increase the capacity for genetics and genomics research. The study is performing comprehensive phenotypic characterization and analyzing environmental and genetic factors from nine clinical centers in four African countries (Ghana, Nigeria, Ethiopia, and Kenya) over a 5-year period. Approximately 4000 participants with specified kidney disease diagnoses and 4000 control participants will be enrolled in the four African countries. In addition, approximately 50 families with hereditary glomerular disease will be enrolled. The study includes both pediatric and adult participants age research infrastructure can be successfully established in Africa. This study will provide clinical, biochemical, and genotypic data that will greatly increase the understanding of CKD in sub-Saharan Africa. Copyright © 2015 by the American Society of Nephrology.

In addition, identification of the collaboration items is another objective of this project. the outcome of this program would be a cornerstone for the nuclear collaboration between Korea and S. Africa. African countries is usually very abundant in the natural resources and developed countries are trying to improve relationships with African countries to secure the natural resources, S. Africa is also very rich with some resources including uranium. Therefore, Korea depending on foreign resources needs to improve the relationship with S. Africa form the viewpoint of securing natural resources. S. Africa has two PWR-type nuclear power plants and is planning to deploy more PWRs to increase the nuclear capacity. In addition, S.

    The topic of the energy sector-and the petroleum sector in particular-in sub-Saharan Africa might well be considered an insignificant issue compared with many of the energy concerns which now command international attention. However, the World Bank believes that it is important for all those in international energy not to forget about the crucial problems facing Africa. They should become informed and concerned about these problems, and, hopefully, work together to bring about a satisfactory solution for an ongoing development dilemma. Simply put, the cost of imported energy to the African economy is exorbitantly high, sapping the resources needed to produce economic growth and social progress. This paper reports that, to address this issue, the World Bank is about to undertake a major initiative-two ground-breaking studies in the field of energy for sub-Saharan Africa. Both of these proposed studies are designed to find ways to reduce the burden of the cost of energy imports, mainly petroleum products, to this continent. One study will examine the design (and, subsequently, the implementation) of a rationalization scheme for the supply and distribution of petroleum products throughout sub-Saharan Africa. The other will consider the feasibility of transporting Nigeria's natural gas to neighbors to the west, all of which presently are importers of energy

    2016-03-01

    The Cognitive Drug Research (CDR) System is a set of nine computerized tests of attention, information processing, working memory, executive control and episodic memory which was designed for repeated assessments in research projects. The CDR System has been used extensively in clinical trials involving healthy volunteers for over 30 years, and a database of 7751 individuals aged 18-87 years has been accumulated for pre-treatment data from these studies. This database has been analysed, and the relationships between the various scores with factors, including age, gender and years of full-time education, have been identified. These analyses are reported in this paper, along with tables of norms for the various key measures from the core tasks stratified by age and gender. These norms can be used for a variety of purposes, including the determination of eligibility for participation in clinical trials and the everyday relevance of research findings from the system. In addition, these norms provide valuable information on gender differences and the effects of normal ageing on major aspects of human cognitive function. © The Author(s) 2016.

    Africa of late has been faced with challenges that require a multidisciplinary and multisectoral approach to address them, and academic and non-academic institutions have played a key role in training and conducting research that would promote the One Health approach. The objective of this review was to document networks and organizations conducting One Health training, research, and outreach in Africa, as one of a series of articles around the world. Data for this review were collected from organizations through key contacts of the authors and their knowledge of networks they have worked with. Web searches were conducted using One Health, training, and research as key words for work done in Africa. Africa has major networks involved in One Health training, research, and outreach, with participation of both academic and non-academic institutions. This review highlights an effort in Africa to form networks to conduct multidisciplinary training and research. The main networks include Afrique One, Southern African Centre for Infectious Disease Surveillance (SACIDS), and One Health Central and Eastern Africa (OHCEA). Both academic and non-academic institutions and organizations have shown an interest to conduct multidisciplinary training and research in Africa for managing challenges that Africa is facing currently, especially the outbreak of infectious diseases.

  3. ICT and Stock Market Nexus in Africa: Evidence from Nigeria and South Africa

    Full Text Available Several studies have examined ICT in relation to stock market development, economic growth and development and other macroeconomic variables. Most of the studies have been on the developed and emerging economies. Studies have been relatively scanty for the developing economies, especially Sub-Saharan Africa. Thus, knowledge gap has been identified in the literature for the African Continent. Pooled data were used in this paper to spur further studies on financial markets in Africa. This paper employed data on functional models adapted from Gompertz curve model for technology diffusion to investigate the effects of ICT on market outcomes of two leading stock exchange markets in Africa during the 1995-2015 periods. Results showed mixed effects of most ICT metrics and moderating variables in the study. Specifically, the effect of mobile telephone on all market indicators was positive and significant. Further, aggregate effect of the ICT proxies and moderating variables on all market indices was statistically significant. The ICT proxies accounted for positive dynamics in market outcomes, market operations and, thus, sine quo non to growth and development of the markets and financial sectors in the Continent. Therefore, more investments in ICT wares and innovation by the stock exchanges and financial sectors in Africa were recommended.

Uma análise que contextualiza a codificação não somente na cronologia dos fatos políticos, mas também, por exemplo, na ciência do direito penal italiana do século XIX. Uma ciência do direito penal – conhecida sob o nome de “escola clássica” – caracterizada por ter levantado algumas bandeiras como a abolição da pena de morte, um dos aspectos apontados, inclusive, como fator que dificultou processo de unificação legislativa no campo penal. Por fim, a título de epílogo, são abordadas as críticas da chamada “escola positiva” que se opunha a algumas tendências liberais do recém-promulgado código. Um liberalismo penal, porém, que é visto em sua ambiguidade: no interior de um código liberal, por exemplo, dispositivos rígidos para combater o dissenso político, e uma normativa extra codicem que mitigava algumas garantias consagradas no código.

    Bipolar disorder impacts negatively on the patient, the family, as well as the society. It taxes the health care services due to a combination of the illness with associated medical and psychiatric comorbidities. In Africa, unfortunately, knowledge of the epidemiology and burden of bipolar disorder is based mainly on studies from the USA and Europe. In this systematic review of literature from Africa, we highlight the epidemiology and burden of bipolar disorder. A systematic review of publications from Africa relating to the epidemiology and burden of bipolar disorder was conducted. Data from community surveys conducted in Nigeria and Ethiopia indicated a lifetime prevalence estimate of 0.1 % to 1.83 for bipolar disorder. Missed diagnosis rate of bipolar disorder was up to 36.2 %. In one study, 8.1 % of the males and 5.4 % of the females reported a previous suicide attempt. A study showed that up to 60 % of patients with bipolar disorder had at least one comorbidity. There were no reports on all-cause mortality and cost of illness. Bipolar disorder is a major mental health problem in Africa. Scientific findings on bipolar disorder from Africa are consistent with the existing literature from other parts of the world. There still exists a dearth of high quality studies addressing the epidemiological, clinical, social, and economic burden of the disorder.

    Full Text Available Neurological involvement is one of the most important clinical manifestations of syphilis and neurological disease occurs in both early and late syphilis. The impact of HIV co-infection on clinical neurosyphilis remains unclear. The highest prevalence of both syphilis and HIV is in Africa. Therefore it might be expected that neurosyphilis would be an important and not uncommon manifestation of syphilis in Africa and frequently occur in association with HIV co-infection; yet few data are available on neurosyphilis in Africa. The aim of this study is to review data on neurosyphilis in Africa since the onset of the HIV epidemic.We searched the literature for references on neurosyphilis in Africa for studies published between the 1st of January 1990 and 15th February 2017. We included case reports, case series, and retrospective and prospective cohort and case-control studies. We did not limit inclusion based on the diagnostic criteria used for neurosyphilis. For retrospective and prospective cohorts, we calculated the proportion of study participants who were diagnosed with neurosyphilis according to the individual study criteria. Depending on the study, we assessed the proportion of patients with syphilis found to have neurosyphilis, and the proportion of patients with neurological syndromes who had neurosyphilis. Due to heterogeneity of data no formal pooling of the data or meta-analysis was undertaken.Amongst patients presenting with a neurological syndrome, three studies of patients with meningitis were identified; neurosyphilis was consistently reported to cause approximately 3% of all cases.

    1993-01-01

    South African President F. W. de Klerk made headlines on March 24 when he admitted to a joint session of parliament that South Africa had once had a supply of nuclear weapons; six of seven planned devices had been completed. South African spokesmen had previously said that Pretoria was capable of building weapons, but they had remained deliberately vague about whether or not any had been built. According to de Klerk, the weapons were dismantled before South Africa signed the Nuclear Non-Proliferation Treaty on July 10, 1991. De Klerk's revelation came in response to charges by the African National Congress and U.S. government officials that South Africa had possibly hidden atomic bomb components and manufacturing plants and that it had been evasive about its stockpile of weapon-grade uranium. A more complete discussion of de Klerk's disclosure and events leading to the admission are explored in this article

    HIV/AIDS disproportionately affects sub-Saharan Africa and 90% of the children with HIV are found there. In addition, non-HIV-infected children in the region are also vulnerable with an estimated 11.4 million AIDS orphans (many of whom are also HIV-positive). South Africa has an estimated 5.5 million people infected with HIV, which is by far the highest in the world. South Africa was reluctant to accept international assistance and began to provide care and treatment much later than its neighbours, and access to care and treatment remains low. Only 36% of children with advanced AIDS living in South Africa were receiving antiretroviral drugs in 2007. This paper not only provides data expressing the extent of the HIV problem affecting children, but also compares neighbouring African countries' successes and failures in combating the disease.

  14. One hundred and twenty-five years of the Annals of Botany. Part 1: the first 50 years (1887–1936)

    Science.gov (United States)

    Jackson, Michael B.

    2015-01-01

    Background The Annals of Botany is a peer-reviewed scientific journal publishing papers on a wide range of topics in plant biology. It first appeared in 1887, making it the oldest continuously published botanical title. The present article gives a historical account of events leading to the founding of the Journal and of its development over the first 50 years. Sources of Information Much of the content is drawn from the Journal’s own records and from extensive Minutes, financial accounts, personal letters and notes relating to the Annals of Botany that were repatriated from University College, University of London in 1999. Documents held at the Royal Botanic Gardens, Kew and at the Oxford University Press Museum were also consulted. Content Emphasis is placed on the individuals who instigated, edited and managed the Annals of Botany up to 1937, especially the nine founding members of the Journal and the background that brought them together and motivated them to start the Annals of Botany. A falling out between two of the founders in 1899 is highlighted since not only did this threaten the Journal’s future but also gives much insight into the personalities of those most closely involved in the Journal during its formative years. The article also examines the way the Journal was funded and how it dealt with its publisher (the University of Oxford’s Clarendon Press), turned itself into a registered company (the Annals of Botany Company) and coped with the travails of the First World War, currency inflation and the Great Depression. Plans to re-start the Journal as a New Series, beginning in 1937, are discussed in the context of the competition the Annals of Botany then faced from younger journals. PMID:25561090

    Full Text Available Under-five child mortality declined 47% since 2000 following the implementation of the United Nation’s (UN Millennium Development Goals. To further reduce under-five child mortality, the UN’s Sustainable Development Goals (SDGs will focus on interventions to address neonatal mortality, a major contributor of under-five mortality. The African region has the highest neonatal mortality rate (28.0 per 1000 live births, followed by that of the Eastern Mediterranean (26.6 and South-East Asia (24.3. This study used the Demographic and Health Survey Birth Recode data (http://dhsprogram.com/data/File-Types-and-Names.cfm to identify high-risk districts and countries for neonatal mortality in two sub-regions of Africa – East Africa and West Africa. Geographically weighted Poisson regression models were estimated to capture the spatially varying relationships between neonatal mortality and dimensions of potential need i care around the time of delivery, ii maternal education, and iii women’s empowerment. In East Africa, neonatal mortality was significantly associated with home births, mothers without an education and mothers whose husbands decided on contraceptive practices, controlling for rural residency. In West Africa, neonatal mortality was also significantly associated with home births, mothers with a primary education and mothers who did not want or plan their last child. Importantly, neonatal mortality associated with home deliveries were explained by maternal exposure to unprotected water sources in East Africa and older maternal age and female sex of infants in West Africa. Future SDG-interventions may target these dimensions of need in priority high-risk districts and countries, to further reduce the burden of neonatal mortality in Africa.

    In March 2014, GSK announced a number of new strategic investments in Africa. One of these included investment of up to 25 million Pounds Sterling (£25 million) to create the world's first R&D Open Lab to increase understanding of non-communicable diseases (NCDs) in Africa. The vision is to create a new global R&D effort with GSK working in partnership with major funders, academic centres and governments to share expertise and resources to conduct high-quality research. The Africa NCD Open Lab will see GSK scientists collaborate with scientific research centres across Africa. An independent advisory board of leading scientists and clinicians will provide input to develop the strategy and selection of NCD research projects within a dynamic and networked open-innovation environment. It is hoped that these research projects will inform prevention and treatment strategies in the future and will enable researchers across academia and industry to discover and develop new medicines to address the specific needs of African patients.

    Adoption of information and communication technologies and access to the Internet is expanding in Africa, but because of the rapid growth elsewhere, a Digital Divide between Africa and the rest of the world exists, and the gap is growing. In many sub-Saharan African countries, education and research sector suffers some of the worst deficiencies in access to the Internet, despite progress in development of NRENs - National Research and Education (cyber) Networks. By contrast, it is widely acknowledged in policy statements from the African Union, the UN, and others that strength in this very sector provides the key to meeting and sustaining Millennium Development Goals. Developed countries with effective cyber-capabilities proclaim the benefits to rich and poor alike arising from the Information Revolution. This is but a dream for many scientists in African institutions. As the world of science becomes increasingly Internet-dependent, so they become increasingly isolated. eGY-Africa is a bottom-up initiative by African scientists and their collaborators to try to reduce this Digital Divide by a campaign of advocacy for better institutional facilities. Four approaches are being taken. The present status of Internet services, problems, and plans are being mapped via a combination of direct measurement of Internet performance (the PingER Project) and a questionnaire-based survey. Information is being gathered on policy statements and initiatives aimed at reducing the Digital Divide, which can be used for arguing the case for better Internet facilities. Groups of concerned scientists are being formed at the national, regional levels in Africa, building on existing networks as much as possible. Opinion in the international science community is being mobilized. Finally, and perhaps most important of all, eGY-Africa is seeking to engage with the many other programs, initiatives, and bodies that share the goal of reducing the Digital Divide - either as a direct policy

The management of the Domain Name System (DNS has developed from a modest undertaking to its current explosive expansion through the new gTLD programme. Africa has boldly entered the arena through the delegation of the .Africa gTLD. This new development heralds an innovative era in the management of the DNS, especially for Africa. The dotAfrica gTLD launch strategy offers several advantages to African governments and traders alike. One of the innovative features of the management of dotAfrica is the fact that a broader set of rights including commercial, cultural, linguistic, religious and personal rights will be protected. Furthermore, African trade mark proprietors and other rights holders are protected, initially at least, by various innovative rights-protection mechanisms. This development is important for African governments and it should form an integral part of right holders' intellectual property management strategy.

Five separate analyses are carried out addressing the question of Nordicization and Europeanization.

  14. On Intensive Late Holocene Iron Mining and Production in the Northern Congo Basin and the Environmental Consequences Associated with Metallurgy in Central Africa

    Lupo, Karen D.; Schmitt, Dave N.; Kiahtipes, Christopher A.; Ndanga, Jean-Paul; Young, D. Craig; Simiti, Bernard

    2015-01-01

    An ongoing question in paleoenvironmental reconstructions of the central African rainforest concerns the role that prehistoric metallurgy played in shaping forest vegetation. Here we report evidence of intensive iron-ore mining and smelting in forested regions of the northern Congo Basin dating to the late Holocene. Volumetric estimates on extracted iron-ore and associated slag mounds from prehistoric sites in the southern Central African Republic suggest large-scale iron production on par with other archaeological and historically-known iron fabrication areas. These data document the first evidence of intensive iron mining and production spanning approximately 90 years prior to colonial occupation (circa AD 1889) and during an interval of time that is poorly represented in the archaeological record. Additional site areas pre-dating these remains by 3-4 centuries reflect an earlier period of iron production on a smaller scale. Microbotanical evidence from a sediment core collected from an adjacent riparian trap shows a reduction in shade-demanding trees in concert with an increase in light-demanding species spanning the time interval associated with iron intensification. This shift occurs during the same time interval when many portions of the Central African witnessed forest transgressions associated with a return to moister and more humid conditions beginning 500-100 years ago. Although data presented here do not demonstrate that iron smelting activities caused widespread vegetation change in Central Africa, we argue that intense mining and smelting can have localized and potentially regional impacts on vegetation communities. These data further demonstrate the high value of pairing archeological and paleoenvironmental analyses to reconstruct regional-scale forest histories. PMID:26161540

  15. Africa gaining importance in world LPG trade

    International Nuclear Information System (INIS)

    Haun, R.R.; Otto, K.W.; Whitley, S.C.

    1997-01-01

    Major LPG projects planned or under way in Africa will increase the importance of that region's presence in world LPG trade. Supplies will nearly double between 1995 and 2005, at which time they will remain steady for at least 10 years. At the same time that exports are leveling, however, increasing domestic demand for PG is likely to reduce export-market participation by Algeria, Nigeria, Egypt, and Libya. The growth of Africa's participation in world LPG supply is reflected in comparisons for the next 15--20 years. Total world supply of LPG in 1995 was about 165 million metric tons (tonnes), of which Africans share was 7.8 million tonnes. By 2000, world supply will grow to slightly more than 200 million tonnes, with Africa's share expected to increase to 13.2 million tonnes (6.6%). And by 2005, world LPG supply will reach nearly 230 million tonnes; Africa's overall supply volumes by that year will be nearly 16.2 million tonnes (7%). World LPG supply for export in 1995 was on order of 44 million tonnes with Africa supply about 4 million tonnes (9%).

El traspaso de poderes se produjo el 1ro. de enero de 1899, es decir, cuando ya había comenzado el curso 1898-1899 el cual, al igual que el anterior, se desarrolló en condiciones totalmente irregulares como consecuencia de la cruenta y del lógico desbalance entre ambos gobiernos. Aunque durante ese curso continuó vigente el plan de estudios de 1880 (y su reforma de 1887 para las facultades de Farmacia y Medicina, disposiciones y órdenes militares emitidas con posterioridad a enero de 1899 introdujeron sucesivas modificaciones durante este. En el curso 1899-1900 se empezó a aplicar un nuevo plan de estudios, el llamado Plan Lanuza, el cual no conllevó cambios significativos en la enseñanza universitaria, pues se limitó a incorporar de nuevo el período preparatorio para todas las facultades, incrementar el número de cátedras y asignaturas y eliminar los estudios propios del doctorado, aunque no el grado. El Plan Lanuza estuvo solo vigente durante el curso 1899-1900. En este trabajo se presentan los principales hechos que caracterizaron la transición de la Universidad de las manos españolas a las estadounidenses y, en particular, los que correspondieron a la Facultad de Farmacia durante los cursos 1898-1899 y 1899-1900.To finish of the Spanish-American-Cuban war, ceased the control over the Cuban island and started that of the United States of America by The Spanish crown.

    1996-01-01

    The role and contribution of the Association of Petroleum Producers of Africa (APPA) to the cooperative development of energy in Africa were described. APPA was created in Lagos in 1987 by eight founding countries, i.e. Algeria, Gabon, Libya, Nigeria, Angola, Benin, Cameroun and Congo. Since then, the Ivory Coast, Egypt, Zaire and Equatorial Guinea have joined APPA. The objectives of APPA are primarily technical. They are to promote amongst its members commercial strategies, an understanding of the energy needs of Africa, and technical collaboration to improve the national energy needs definition in Africa. Current petroleum and natural gas reserves and crude oil and refined products production for the African continent were also reviewed

    Hydatid cysts of Echinococcus felidis are described from the hippopotamus (Hippopotamus amphibius) from Mpumalanga Province, South Africa. Among six hippopotami investigated, hepatic hydatids were found in three. The identification was based on mitochondrial and nuclear DNA sequences. In addition, the rostellar hook morphology was analysed. This is the first morphological description of the metacestode of E. felidis, and the first molecularly confirmed report of the intermediate host of E. felidis in South Africa. The definitive host of E. felidis in South Africa is the lion (Panthera leo). Copyright © 2017 Elsevier B.V. All rights reserved.

    W H Andrews qualified as a veterinarian in London in 1908 and was recruited soon after, in 1909, by Sir Arnold Theiler to join the staff of the newly established veterinary laboratory at Onderstepoort. After initial studies on the treatment of trypanosomosis and on snake venoms he was deployed by Theiler in 1911 to start research on lamsiekte (botulism)at a field station on the farm Kaffraria near Christiana, where he met and married his wife Doris. After a stint as Captain in the SA Veterinary Corps during World War I he succeeded D T Mitchell as head of the Allerton Laboratory in 1918, where he excelled in research on toxic plants, inter alia identifying Matricaria nigellaefolia as the cause of staggers in cattle. When the Faculty of Veterinary Science was established in 1920 he was appointed as the first Professor of Physiology. After the graduation of the first class in 1924, and due to health problems, he returned to the UK, first to the Royal Veterinary College and then to the Weybridge Veterinary Laboratories of which he became Director in 1927. After his retirement in 1947 he returned to South Africa as a guest worker at Onderstepoort where he again became involved in teaching physiology when Prof. Quin unexpectedly died in 1950. Andrews died in Pretoria in 1953 and was buried in the Rebecca Street Cemetery.

  3. China-Africa: New Directions of Cooperation

    2015-12-01

    Full Text Available This article analyzes the policy of fifth generation of Chinese leadership with regard to African states. The article deals with the concept of “Chinese Dream”, which was first declared in Africa, an innovative model of international cooperation in the framework of the formation of “economic zone of the Silk Road”. The authors reveal three basic directions of cooperation - political, economic and humanitarian cooperation. Political cooperation is characterized by the activation of mutual visits at the highest level, the interaction in the framework of the UN General Assembly, participation in UN peacekeeping operations. Economic cooperation is characterized by the activation of bilateral trade, the transition to a “modernized version of” investment cooperation, implementation of the strategy of “going abroad” of Chinese products, imports of natural resources from Africa, creating jobs for the local population, financing of infrastructure projects, the transfer of labor-intensive industries in Africa. Humanitarian cooperation includes training program for Africa, the implementation of the Sino-African programs, technology partnerships, research and exchange, and the China-Africa Forum “Think Tank”. Cooperation in health care also plays an important role. The authors note that the new Chinese leadership declares transition to an upgraded version of the Sino-African cooperation.

  4. Africa and the global carbon cycle

    2007-03-01

    Full Text Available Abstract The African continent has a large and growing role in the global carbon cycle, with potentially important climate change implications. However, the sparse observation network in and around the African continent means that Africa is one of the weakest links in our understanding of the global carbon cycle. Here, we combine data from regional and global inventories as well as forward and inverse model analyses to appraise what is known about Africa's continental-scale carbon dynamics. With low fossil emissions and productivity that largely compensates respiration, land conversion is Africa's primary net carbon release, much of it through burning of forests. Savanna fire emissions, though large, represent a short-term source that is offset by ensuing regrowth. While current data suggest a near zero decadal-scale carbon balance, interannual climate fluctuations (especially drought induce sizeable variability in net ecosystem productivity and savanna fire emissions such that Africa is a major source of interannual variability in global atmospheric CO2. Considering the continent's sizeable carbon stocks, their seemingly high vulnerability to anticipated climate and land use change, as well as growing populations and industrialization, Africa's carbon emissions and their interannual variability are likely to undergo substantial increases through the 21st century.

    The potential heritage of apartheid still affects energy availability in South Africa. This article describes a new Energy Policy White paper, to be presented to Parliament, which will start to rectify current inequalities. Most of the black citizens have no access to electricity, while the affluent white minority have cheap electricity readily available to them. The complexities of funding necessary changes are addressed. South Africa`s low-cost coal reserves, mined from opencast pits next to power stations, are likely to continue to be exploited. As yet the country`s solar potential is unlikely to be developed because of the availability of coal. The production of electricity and the future of liquid fuel industries are likely to remain in crisis, even after the White Paper`s implementation. (UK)

Much the same applies to portable palaeoart of Africa. The current record is clearly one of paucity of evidence, in contrast to some other continents. Nevertheless, an initial synthesis is attempted, and some preliminary comparisons with the other continents are attempted. Certain parallels with the existing record of southern Asia are defined.

  15. The Determinants of Household Poverty in South Africa

    Directory of Open Access Journals (Sweden)

    Ajuruchukwu Obi

    2016-12-01

    Full Text Available South Africa was privileged to be part of the MDGs agenda which was adopted in 2000. One of the aims of MDGs was to reduce extreme poverty by half in 2015. For that reason, South Africa integrated policies and strategies to rid poverty by half to that of United Nations (UN. Through all the combined policy approaches, South Africa has successfully achieved the target of halving the population living below PPP$1.25c per person per day. Whichever threshold used, the results showed that the percentage share of people living below poverty line has now decreased from 11.3 per cent in 2000 to 4.0 per cent in 2011. However, these reports are not reflecting the exact poor’s experiences because at household level there is still an outright poverty. Therefore, if the national poverty report gives a good picture about South African poverty status whereas there is still prevalence of poverty at household level, there are high chances that wrong policies in regard to poverty reduction strategies will be wrought. Hence this paper focuses on the determinants of household poverty in South Africa. The sole aim of this paper is to assess the determinants of household poverty in South Africa. The reviewed literature on determinants of poverty in South Africa would enable policy makers to see the effect of demographic characteristics on poverty in South Africa. Thus, strategies and policies aimed at alleviating poverty in South Africa can be directed to the discussed factors.

  16. Aspects of Digital Forensics in South Africa

    Directory of Open Access Journals (Sweden)

    Jacques Ophoff

    2016-10-01

    Full Text Available This paper explores the issues facing digital forensics in South Africa. It examines particular cyber threats and cyber threat levels for South Africa and the challenges in addressing the cybercrimes in the country through digital forensics. The paper paints a picture of the cybercrime threats facing South Africa and argues for the need to develop a skill base in digital forensics in order to counter the threats through detection of cybercrime, by analyzing cybercrime reports, consideration of current legislation, and an analysis of computer forensics course provision in South African universities. The paper argues that there is a need to develop digital forensics skills in South Africa through university programs, in addition to associated training courses. The intention in this paper is to promote debate and discussion in order to identify the cyber threats to South Africa and to encourage the development of a framework to counter the threats – through legislation, high tech law enforcement structures and protocols, digital forensics education, digital forensics skills development, and a public and business awareness of cybercrime threats.

    Sub-Saharan Africa has a shortage of well-trained biomedical research methodologists, in particular, biostatisticians. In July 2014, a group of biostatisticians and researchers from the region attended a brainstorming workshop to identify ways in which to reduce the deficit in this critical skill. The workshop recognized that recommendations from previous workshops on building biostatistics capacity in sub-Saharan Africa had not been implemented. The discussions culminated with a proposal to setup an Africa Center for Biostatistical Excellence, a collaborative effort across academic and researcher institutions within the region, as a vehicle for promoting biostatistics capacity building through specialized academic masters programs as well as regular workshops targeting researchers.

    2013-10-01

    Nephrology is a 'Cinderella speciality', a disregarded area of health care, in Africa. Other health issues have relegated the treatment of kidney diseases to a low priority status, and the cost of treating the more common and widespread communicable diseases, financial mismanagement and corruption in many countries has sounded the death knell for expensive therapies such as dialysis. The communicable diseases that have devastated the health systems around Africa are tuberculosis and HIV/AIDS. Until recently, very little information was available on the impact of HIV on acute and chronic dialysis admissions. Patients with acute kidney injury (AKI) in most of Africa are seldom treated because of great distances to travel, lack of expertise, poverty and poor sustainable funding for health matters. An acute peritoneal dialysis (PD) programme has now been initiated in Tanzania but the sustainability of this project will be tested in the future. The International Society of Nephrology (ISN) has developed a training programme for nephrologists from developing countries, which may now be bearing fruit. A report from the sub-Saharan Africa region shows that the numbers of patients on dialysis and those diagnosed with chronic kidney disease (CKD) has increased significantly. Other ISN-sponsored programmes such as Continuing Medical Education activities for physicians and community screening projects have had far-reaching positive effects. Government funding for a dialysis programme is well established in South Africa, but this funding is limited so that the numbers accepted for public dialysis are restricted. Consequently in the Western Cape province of South Africa, a 'category system' has been formulated to attempt to cope with this unacceptable and restrictive ruling.

  3. Sub-Saharan Africa thirty years hence.

    Science.gov (United States)

    Wheeler, J

    1986-11-01

    By the year 2015, Sub-Saharan Africa's population will probably rise from a 1985 level of about 460 million to about 1.1 billion. Today Africa's population is growing at a rate of roughly 3% a year, with exceptionally high growth rates in some countries. The leaders of Africa, and those who wish to help Africa, confront difficult and urgent problems of drought, political and military conflict, accumulated debt, lower commodity prices, and other factors of immediate and important concern. Africa has given education a high priority and should be as well known for its success in increasing school enrollment as it is for its relative failures in other areas. A projected population of 1.1 billion people and a fertility rate down to 30/1000 by the year 2015 suggests that the number of children old enough to enter primary school will be of the order of 30 million a year at this time. The working-age population will grow from 235 million now to perhaps 600 million in 30 years. The urban population has been growing at about 6% a year--twice the pace of population increase. All of these situations will have an effect on environment, water, and health. Coping with Africa's burgeoning population in terms of children in school, the demand on health systems, the need for jobs, achieving an adequate diet, the provision of basic urban services, and all the rest, is an extraordinary challenge. While the government's role is critical, success at the sectoral level almost always means cost recovery, administration decentralized to the community or to the private sector, and program implementation that does not burden the budget.

    Full Text Available El presente trabajo constituye un estudio preliminar que forma parte de un proyecto más amplio acreditado por la Universidad Nacional de La Plata y avalado por la Municipalidad de esa localidad "El Cementerio de La Plata. Su contexto histórico". Nuestra investigación se basó fundamentalmente en el análisis de las actas de defunción del Archivo del Cementerio Municipal con el fin de indagar sobre la incidencia diferencial o no de las causas de muerte en relación con la nacionalidad, el sexo, la edad, la profesión, entre otras. Estos datos fueron volcados en planillas con las que se sistematizó la información para toda la población. A partir de esta población, se determinó una muestra compuesta por todos los individuos de ambos sexos que se encuentran en las sepulturas en tierra y abarca el primer año de funcionamiento del Cementerio Municipal. El objetivo del presente trabajo fue caracterizar cómo se distribuyeron las causas de muerte y su incidencia sobre los grupos de edad, género y grupo social, en los decesos ocurridos durante 1887. Según se desprende de los datos analizados, la probabilidad de fallecer antes de cumplir el año de vida es de más del 60%. Las razones para esta alta mortalidad infantil deberán buscarse en las condiciones sanitarias y nutricionales imperantes en la época y para este grupo social, considerando las enfermedades de mayor incidencia en los subadultos; también deben agregarse algunos casos de fallecimiento en los primeros días de vida por falta de desarrollo. En este grupo de edad las causas de muerte más comunes corresponden a las que pertenecen al sistema digestivo, respiratorio, infecciosas y en adultos a enfermedades cardiovasculares, cerebrales, etc.

    2018-01-01

    There is paucity of physician-scientists in Africa, resulting in overt dependence of clinical practice on research findings from advanced "first world" countries. Physician-scientists include individuals with a medical degree alone or combined with other advanced degrees (e.g. MD/MBChB and PhD) with a career path in biomedical/ translational and patient-oriented/evaluative science research. The paucity of clinically trained research scientists in Africa could result in dire consequences as exemplified in the recent Ebola virus epidemic in West Africa, where shortage of skilled clinical scientists, played a major role in disease progression and mortality. Here we contextualise the role of physician-scientist in health care management, highlight factors limiting the training of physician-scientist in Africa and proffer implementable recommendations to address these factors.

  10. Evolution of Corruption in Sub-Saharan Africa - from Nkruma To Mutharika The 2nd: Case Study Of South Africa

    Directory of Open Access Journals (Sweden)

    Mavhungu Abel Mafukata

    2015-03-01

    Full Text Available Since Sub-Saharan Africa's first independence in Ghana, the region has experienced massive and costly political and bureaucratic corruption within public service and administration. The causes of the corruption, its nature and form are wide and intertwined. In Sub-Saharan Africa, efforts to curb corruption have failed to discard it. The paper focused on the period from Nkruma in Ghana to Mutharika the 2nd in Malawi. This paper reviewed existing literature on political and bureaucratic corruption in Sub-Saharan Africa while on the other hand the paper employed key informant interviews to gather the required data to investigate, analyse and profile the genesis and evolution of corruption in Sub-Saharan Africa. The key informant interviews were employed to solicit public views and opinion from nineteen key informant participants (n=19 selected from 11 countries in Sub-Saharan Africa. The paper found that corruption is legendary; has entrenched itself to becoming some sort of culture in the region, and has become the most difficult socio-economic challenge to resolve in the region despite the various anti-corruption efforts employed by stakeholders to curb it. It emerged through the study that law-enforcement efforts against corruption need some reinforcement in order to be effective and eficient in uprooting corruption in the region. If Sub-Saharan Africa fails to address its corruption challenge, its development prospects would seriously curtailed.

  11. The Consortium for NCD Prevention and Control in Sub-Saharan Africa (CNCD-Africa): from concept to practice.

    Science.gov (United States)

    Amuyunzu-Nyamongo, Mary; Owuor, Jared O; Blanchard, Claire

    2013-12-01

    CNCD-Africa was established in July 2009 in response to and in recognition of the continuously increasing burden of diseases such as injuries, non-communicable diseases (NCDs) and mental health in low- and middle-income countries, and specifically in countries of sub-Saharan Africa. CNCD-Africa aims to comprehensively address specific and common objectives while building capacity in the region to prevent and control NCDs. With support from key partners and funders, and a keen interest in opportunities to address NCDs from health promotion and equity perspectives, the Consortium has excelled in four key areas: convening; knowledge generation and sharing; advocacy; and networking. However, the path to successful and sustainable efforts remains laden with challenges and barriers. Retaining interest of network partners through flagship efforts and continued efforts to ascertain support from local and international partners with interest in NCDs across the region remain essential to CNCD-Africa core activities. A key lesson learnt from the early years of CNCD-Africa is that existing regional platforms can and should be used to showcase what is being done locally, and to share best practices and best-buys. In addition, partnerships and stakeholder involvement have been key for CNCD-Africa and are essential to NCD action. Sustaining such partnerships requires incentives for the various partners to keep actively involved in NCD action. This can be achieved through joint inception, project planning, implementation, monitoring and evaluation. Another ingredient for success seems to be innovative financing for NCD efforts, which is possible through the establishment and sustaining of regional and global partnerships that are robust, locally relevant and respond to country needs.

    Adoption of information and communication technologies and access to the Internet is expanding in Africa, but because of the rapid growth elsewhere, a Digital Divide between Africa and the rest of the world exists. In many sub-Saharan African countries, education and research sector suffers some of the worst deficiencies in access to the Internet, despite progress in the development of NRENs - National Research and Education (cyber) Networks. By contrast, it is widely acknowledged in policy statements from the African Union, the UN, and others that strength in this very sector provides the key to meeting and sustaining Millennium Development Goals. Developed countries with effective cyber-capabilities proclaim the benefits to rich and poor alike arising from the Information Revolution. This is still a dream for many scientists in African institutions. As the world of science becomes increasingly Internet-dependent, so they become increasingly isolated. eGY-Africa is a bottom-up initiative by African scientists and their collaborators to try to reduce this digital divide by a campaign of advocacy for better institutional facilities. Four approaches are being taken. The present status of Internet services, problems, and plans are being mapped via a combination of direct measurement of Internet performance (the PingER Project) and a questionnaire-based survey. Information is being gathered on policy statements and initiatives aimed at reducing the digital divide, which can be used for arguing the case for better Internet facilities. Groups of concerned scientists are being formed at the national, regional levels in Africa, building on existing networks as much as possible. Opinion in the international science community is being mobilized. Finally, and perhaps most important of all, eGY-Africa is seeking to engage with the many other programs, initiatives, and bodies that share the goal of reducing the digital divide - either as a direct policy objective, or indirectly

  15. Telerehabilitation in South Africa - is there a way forward?

    2011-01-01

    South Africa, like the rest of sub-Saharan Africa, has a disproportionate burden of disease and a shortage of health professionals. Telemedicine has been identified as a possible way of overcoming part of the problem but telemedicine has not been widely adopted. In the public sector hospitals in South Africa which serve 82% of the population there are 2.5 physiotherapists and 2 occupational therapists per 100,000 people served. The extent of telerehabilitation in South Africa is unknown. A literature review of telerehabilitation found no papers from South Africa. A survey of the heads of university departments of physiotherapy, occupational therapy and speech and language pathology revealed limited knowledge of telerehabilitation. Telerehabilitation services are confined to follow-up of patients at some institutions by telephone, fax or email. There is need to raise awareness among therapists if telerehabilitation is to become a reality in South Africa. Future actions are outlined.

  20. Powering Africa: Meeting the financing and reform challenges

    International Nuclear Information System (INIS)

    Eberhard, Anton; Shkaratan, Maria

    2012-01-01

    Sub-Saharan Africa faces chronic power problems, including insufficient generation capacity, low connectivity, poor reliability, and high costs, all of which constrain development. The investment requirements to meet Africa's power needs are noted and strategies to address the funding gap are set out. The time for an ideological debate on public versus private investment is over—both are needed. Africa's key challenges are the management of hybrid power markets, the reform of state-owned utilities, cost-reflective pricing, better targeting of subsidies, the nimbler rollout of electrification, and stronger regional integration. - Highlights: ► Africa has insufficient power generation, low connectivity, poor reliability, and high costs. ► Investment requirements to meet Africa's power needs are calculated. ► Key challenges are the management of hybrid power markets and the reform of state-owned utilities. ► Other challenges are cost-reflective pricing, extending access, and stronger regional integration.

  3. Development of oral health in Africa.

    Thorpe, Samuel J

    2003-01-01

    Around 80% of African communities can be considered to be materially deprived. The presence of widespread poverty and underdevelopment in Africa means that communities are increasingly exposed to all of the major environmental determinants of oral disease. Previous approaches to oral health in Africa have failed to recognize the epidemiological priorities of the region or identify reliable and appropriate strategies to address them. Efforts have consisted of providing unplanned, ad hoc and spasmodic curative oral health services, which in most cases are poorly distributed and only reach affluent or urban communities. Realizing the limited impact of existing strategies, the World Health Organization Regional Office for Africa (WHO/AFRO) developed a regional oral health strategy to assist African countries and their partners in identifying priorities and planning preventive-oriented programmes, particularly at the district level. The long-term objective is to provide equitable and universal access to cost-effective quality oral healthcare and thereby significantly reduce the incidence of oral diseases in Africa.

    Africa's hydroelectric power plants are not able to perform at greater than 30 per cent of their installed capacity, despite the fact that Africa has abundant hydroelectric resources. Droughts and floods attributed to climate change are presenting challenges to the effective management and distribution of hydroelectric power supplies. This paper identified climate change-related barriers against hydroelectric power development in Africa. Case studies of 3 hydroelectric power projects in Nigeria were considered. Rainfall intensity data for a 25-year period were analyzed. The study showed that while the hydroelectric power plants are capable of supplying more power, most dams in Africa are prone to erosion and flash flooding. The sedimentation of reservoirs and natural lakes are also posing significant water management problems. Redesigns are needed in order to reduce risk. The new hydroelectric projects should be designed to ensure that environmental impacts are minimized. A river basin management approach was recommended in order to improve industrial water supplies, power generation, and recreational aspects of waterways. 11 refs., 2 tabs.

  6. Marketing of irradiated commodities in South Africa

    Energy Technology Data Exchange (ETDEWEB)

    Du Plessis, T A; Stevens, R C.B.

    1985-01-01

    Although the industrial exploitation of radiation processing in the medical and allied fields has been successfully marketed and applied for the past two decades in South Africa, the introduction of food radurisation on an industrial level adds a completely new dimension to the marketing of this processing technique. Extensive research into the use of radiation for the treatment of various foodstuffs has been carried out by the Nuclear Development Corporation of South Africa for more than a decade, resulting in South Africa being one of the first countries where a commercial irradiator dedicated to this branch of radiation processing, was established. The marketing of this process is especially difficult due to the emotive aspects associated with radiation and man's sensitive reaction to anything pertaining to his food. This situation was made even more difficult by the general public's apprehension towards nuclear activities throughout the world. Details are given of the steps taken in South Africa to transform the unfavourable public image associated with the process. The approach proved to be very successful and greatly assisted in creating a climate whereby the public in South Africa today generally has a favourable attitude towards the radurisation of foodstuffs.

  8. A continent in chaos: Africa's environmental issues.

    Science.gov (United States)

    Clay, R

    1994-12-01

    Half of Africa's almost 450 million inhabitants have no access to health services, while two-thirds lack safe drinking water, according to a 1991 report by the World Bank. Most Africans are also seriously affected by poverty, civil war, indoor and outdoor pollutants, diarrhea-causing microbes, tropical diseases such as malaria, rapid population growth, inadequate sanitation and sewage treatment, poor environmental management, corrupt government policies, desertification and deforestation, mining, and the overuse of pesticides and insecticides. Environmentally-related diseases compromise the continent's productivity, making it more difficult to generate revenue to fight the environmental health problems. Industrial pollutants remain rare, however, since almost 80% of sub-Saharan Africa remains pastoral or agro-pastoral. Even so, urbanization is exposing growing numbers of sub-Saharan Africans to hazardous and toxic wastes. Developing countries ship their most dangerous wastes to Africa because their own domestic environmental laws and the high costs of disposal make it difficult and expensive to dispose of them at home. The author discusses population growth in Africa; the lack of good data on the environment and health in Africa; infant and child mortality; water, sewage, and garbage; agriculture, mining, and industry; and sustainable development and the future.

  9. [[History of Community Health in Africa. The Swiss Medical Missionaries' Endeavour in South Africa].

    2015-01-01

    It was not Dutch settlers nor British colonizers who introduced public and community health practice in north-eastern South Africa but medical doctors of the Swiss mission in southern Africa. While the history of medical knowledge transfer into 19th-20th century Africa emphasises colonial powers, this paper shows how countries without colonies contributed to expand western medical cultures, including public health. The Swiss took advantage of the local authorities' negligence, and implemented their own model of medicalization of African societies, understood as the way of improving health standards. They moved from a tolerated hospital-centred medicine to the practice of community health, which was uncommon at the time. Elim hospital's physicians moved back boundaries of segregationist policies, and sometime gave the impression of being involved in the political struggle against Apartheid. Thus, Swiss public health activities could later be seen as sorts of seeds that were planted and would partly reappear in 1994 with the ANC-projected national health policy.

  15. A landslide susceptibility map of Africa

    2017-04-01

    Studies on landslide risks and fatalities indicate that landslides are a global threat to humans, infrastructure and the environment, certainly in Africa. Nonetheless our understanding of the spatial patterns of landslides and rockfalls on this continent is very limited. Also in global landslide susceptibility maps, Africa is mostly underrepresented in the inventories used to construct these maps. As a result, predicted landslide susceptibilities remain subject to very large uncertainties. This research aims to produce a first continent-wide landslide susceptibility map for Africa, calibrated with a well-distributed landslide dataset. As a first step, we compiled all available landslide inventories for Africa. This data was supplemented by additional landslide mapping with Google Earth in underrepresented regions. This way, we compiled 60 landslide inventories from the literature (ca. 11000 landslides) and an additional 6500 landslides through mapping in Google Earth (including 1500 rockfalls). Various environmental variables such as slope, lithology, soil characteristics, land use, precipitation and seismic activity, were investigated for their significance in explaining the observed spatial patterns of landslides. To account for potential mapping biases in our dataset, we used Monte Carlo simulations that selected different subsets of mapped landslides, tested the significance of the considered environmental variables and evaluated the performance of the fitted multiple logistic regression model against another subset of mapped landslides. Based on these analyses, we constructed two landslide susceptibility maps for Africa: one for all landslide types and one excluding rockfalls. In both maps, topography, lithology and seismic activity were the most significant variables. The latter factor may be surprising, given the overall limited degree of seismicity in Africa. However, its significance indicates that frequent seismic events may serve as in important

Aside from being generally low, saving rates in most of Africa have shown consistent decline over the last thirty years. These savings figures must be considered tentative, because they are derived as a residual in the national accounts from expenditure and production data that are themselves quite unreliable.

  18. Counselling Psychology in South Africa.

    Science.gov (United States)

    Bantjes, Jason; Kagee, Ashraf; Young, Charles

    The origin and development of counselling psychology in South Africa has been profoundly influenced by the country's socio-political history and the impact of apartheid. As a result of this, counselling psychologists in the country face a number of challenges and opportunities for the future. In this paper we provide a portrait of counselling psychology in South Africa by describing the current character of the specialty and the context in which South African psychologists work. We critically discuss the challenges that the specialty faces to meet the country's mental health care needs, contest the current Scope of Practice; affirm multiculturalism without essentializing or reifying race and ethnicity, and build an evidence base for community interventions in the country. We also consider how, in the future, counselling psychologists in South Africa may make a more meaningful contribution within public health and the country's health care and education systems.

  19. Uranium in South Africa: 1985

    International Nuclear Information System (INIS)

    1986-03-01

    South Africa's participation in the nuclear industry was limited to the production of uranium and research, with minor commercial activities. The commissioning of the Koeberg Nuclear power station in 1984 placed South Africa firmly on the path of commercial nuclear power generation. A unique, locally developed uranium enrichment process will enable South Africa to be self-sufficient in its nuclear-fuel needs. Uranium has always been of secondary importance to gold as a target commodity in the exploration of the quartz-pebble conglomerates. In the Witwatersrand Basin it is estimated that in excess of R100 million was spent on exploration during 1985. This was spent primarily in the search for gold but as many of the gold reefs are uraniferous, new uranium resources are being discovered concurrently with those of gold. Uranium mineralization is present in rocks which encompass almost the whole of the geological history of South Africa. Significant mineralization is restricted to five fairly well-defined time periods. Each period is characterized by a distinct type or combination of types of mineralization. Resource estimates are divided into separate categories that reflect different levels of confidence in the quantities reported. The resource categories are further separated into levels of exploitability based on the estimated cost of their exploitation. A major part (87%) of South Africa's uranium resources is present as a by-product of gold in the quartz-pebble conglomerates of the Witwatersrand Basin. The uranium resources in the reasonably assured resources (RAR) and estimated additional resources - category I (EAR-I) catogories were 483 300 t U. Production during 1985 was 4880 t U. Although a production peaking at over 1200 t U/a is theoretically attainable, it is considered, from market projections, that a production ceilling of 10 000 t U/a would be more realistic

  8. Effects of South Africa’s Economic Growth on Sub-Saharan Africa

    2007-06-01

    Full Text Available Major countries, such as the United States, Japan, and China have already recognized the potential of Africa’s markets. Korea has also taken notice of Africa's diverse export markets recently. However, Africa is comprised of 53 different countries and, as a result, entry into the region poses a formidable strategic challenge. Korean authorities and export groups have suggested a "3 plus 2 Country Strategy" in order to make inroads into the African region. This paper contributes to discussions of this strategy by comparing the effects of economic growth in South Africa and Nigeria on Sub-Saharan Africa. In addition, because economic power in Africa is concentrated in a small number of countries, whose market characteristics are different from those of integrated unions, the determinants of economic growth in Africa as a whole and unions may be different. This paper investigates whether or not this is, in fact, the case. The empirical results can be summarized as follows: First, the effects of South Africa's economic growth on Sub-Saharan Africa and the SADC (a representative union of South Africa are much larger than the effects of Nigeria's growth on Sub-Saharan Africa and the ECOWAS (a representative union of Nigeria. These empirical results imply that the preferred country to pursue economic cooperation with is South Africa. Second, we confirm that determinants of economic growth are different for Africa and the unions. The main determinant of growth in African countries may be the population ratio, but in the SADC, growth appears to be determined by ratio trade volumes of GDP. Finally, we also find that the ratio investments of GDP have a positive influence on the economic growth of both Africa and SADC.

  11. Wind power potential and integration in Africa

    Directory of Open Access Journals (Sweden)

    Agbetuyi, A.F.

    2013-03-01

    Full Text Available Wind energy penetration into power networks is increasing very rapidly all over the world. The great concern about global warming and continued apprehensions about nuclear power around the world should drive most countries in Africa into strong demand for wind generation because of its advantages which include the absence of harmful emissions, very clean and almost infinite availability of wind that is converted into electricity. This paper shows the power available in the wind. It also gives an overview of the wind power potential and integration in some selected Africa countries like Egypt, Morocco, South Africa and Nigeria and the challenges of wind power integration in Africa’s continent are also discussed. The Northern part of Africa is known to be Africa’s Wind pioneers having installed and connected the Wind Energy Converters (WEC to the grid. About 97% of the continent’s total wind installations are located in Egypt, Morocco and Tunisia. Research work should commence on the identified sites with high wind speeds in those selected Africa countries, so that those potential sites can be connected to the grid. This is because the ability of a site to sufficiently accommodate wind generation not only depends on wind speeds but on its ability to interconnect to the existing grid. If these wind energy potentials are tapped and connected to the grid, the erratic and epileptic power supply facing most countries in Africa will be reduced; thereby reducing rural-urban migration and more jobs will be created.

  12. Importance of bovine mastitis in Africa.

    Bovine mastitis is an important animal production disease that affects the dairy industry globally. Studies have estimated the prevalence of this disease in approximately 30% of African countries, with the highest prevalence found in Ethiopia. This is despite the wide cattle distribution in Africa, and the largest number of dairy farms and herds in countries such as South Africa, Kenya and Uganda. Furthermore, the estimated financial losses due to direct and indirect impacts of bovine mastitis are lacking in this continent. Therefore, intensive research efforts will help determine the continent-wide economic impacts and advance careful monitoring of disease prevalence and epidemiology. Here, published cases supporting the occurrence and importance of bovine mastitis in certain regions of Africa are outlined.

    According to FAO (2005) about 13 million hectares of the word’s forest are lost due to deforestation. Naoto (2006) found Africa to lead the list of countries with the highest rate of deforestation. This worrisome situation is further aggravated by the possible negative impacts of climate change due to an increase in the mean global temperature. Evidence supports that Africa is most likely to suffer the most the devastating impacts of natural calamities such as droughts and floods. This paper ...

  17. ADOPTION OF ISO 9001 QUALITY MANAGEMENT STANDARD IN AFRICA

    Directory of Open Access Journals (Sweden)

    Erlantz Allur

    2014-03-01

    Full Text Available This article analyzes the dissemination of ISO 9001, the main global management standards, within Africa. The work refers to the diffusion of ISO 9001 standard in terms of its certification intensity. In this article, the dissemination of ISO 9001 in Africa has been analyzed. The findings reveal that the diffusion of the standard in this continent is not very relevant, what might be seen as an indicator of the process of Africa's trade marginalization in the age of globalization. The general certification intensity of the continet is of 0.18; in other words, the proportion of the contribution of Africa to the global GDP of the world is more than five times superior to the proportion of ISO 9001 certificates located in Africa. By means of the logistic model the dissemination of ISO 9001 is forecasted, and it has been observed that the diffusion of ISO 9001 in Africa is in an 85% of its saturation point. Taking into account this model, it's expected that the dissemination of ISO 9001 will be growing until 2020.

    Bantjes, Jason; Kagee, Ashraf; Young, Charles

    2016-01-01

    The origin and development of counselling psychology in South Africa has been profoundly influenced by the country’s socio-political history and the impact of apartheid. As a result of this, counselling psychologists in the country face a number of challenges and opportunities for the future. In this paper we provide a portrait of counselling psychology in South Africa by describing the current character of the specialty and the context in which South African psychologists work. We critically discuss the challenges that the specialty faces to meet the country’s mental health care needs, contest the current Scope of Practice; affirm multiculturalism without essentializing or reifying race and ethnicity, and build an evidence base for community interventions in the country. We also consider how, in the future, counselling psychologists in South Africa may make a more meaningful contribution within public health and the country’s health care and education systems.

  20. Foot-and-mouth Disease Transmission in Africa: Implications for Control, a Review.

    Tekleghiorghis, T; Moormann, R J M; Weerdmeester, K; Dekker, A

    2016-04-01

    In Africa, for the control of foot-and-mouth disease (FMD), more information is needed on the spread of the disease at local, regional and inter-regional level. The aim of this review is to identify the role that animal husbandry, trade and wildlife have on the transmission of FMD and to provide a scientific basis for different FMD control measures in Africa. Review of literature, published reports and databases shows that there is more long distance spread of FMD virus serotypes within North, West, Central and East Africa than in southern Africa. In North, West, Central and East Africa migratory animal husbandry systems often related with search for grazing and water as well as trade are practiced to a greater extent than in southern Africa. In southern Africa, the role of African buffalo (Syncerus caffer) is more extensively studied than in the other parts of Africa, but based on the densities of African buffalo in Central and East Africa, one would assume that buffalo should also play a role in the epidemiology of FMD in this part of Africa. More sampling of buffalo is necessary in West, Central and East Africa. The genetic analysis of virus strains has proven to be valuable to increase our understanding in the spread of FMD in Africa. This review shows that there is a difference in FMD occurrence between southern Africa and the rest of the continent; this distinction is most likely based on differences in animal husbandry and trade systems. Insufficient data on FMD in wildlife outside southern Africa is limiting our understanding on the role wildlife plays in the transmission of FMD in the other buffalo inhabited areas of Africa. © 2014 Blackwell Verlag GmbH.

    Infections caused by high-risk human papillomavirus (HPV) are responsible for 7.7% of cancers in developing countries, mainly cervical cancer. This disease is steadily increasing in sub-Saharan Africa, with more than 75,000 new cases and 50,000 deaths yearly, further increased by HIV infection. Areas covered: The current status of cervical cancer associated with HPV in sub-Saharan Africa has been systematically revised. The main issues discussed here are related to the public health burden of cervical cancer in sub-Saharan Africa and predictions for the coming decades, including molecular epidemiology and determinants of HPV infection in Africa, and promising prevention measures currently being evaluated in Africa. Expert commentary: By the year 2030, cervical cancer will kill more than 443,000 women yearly worldwide, most of them in sub-Saharan Africa. The increase in the incidence of cervical cancer in Africa could counteract the progress made by African women in reducing maternal mortality and longevity. Nevertheless, cervical cancer is a potentially preventable noncommunicable disease, and intervention strategies to eliminate cervical cancer as a public health concern should be urgently implemented.

    Research groups in Planetary and Space Sciences (PSS) are now emerging in Africa, but remain few, scattered and underfunded. It is our conviction that the exclusion of 20% of the world's population from taking part in the fascinating discoveries about our solar system impoverishes global science. The benefits of a coordinated PSS program for Africa's youth have motivated a call for international support and investment [1] into an Africa Initiative for Planetary and Space Sciences. At the time of writing, the call has been endorsed by 230 scientists and 19 institutions or international organizations (follow the map of endorsements on https://africapss.org). More than 70 African Planetary scientists have already joined the initiative and about 150 researchers in non-African countries are ready to participate in research and in capacitity building of PSS programs in Africa. We will briefly review in this presentation the status of PSS in Africa [2] and illustrate some of the major achievements of African Planetary and Space scientists, including the search for meteorites or impact craters, the observations of exoplanets, and space weather investigations. We will then discuss a road map for its expansion, with an emphasis on the role that planetary and space scientists can play to support scientific and economic development in Africa. The initiative is conceived as a network of projects with Principal Investigators based in Africa. A Steering Committee is being constituted to coordinate these efforts and contribute to fund-raising and identification of potential private and public sponsors. The scientific strategy of each group within the network will be developed in cooperation with international experts, taking into account the local expertise, available equipment and facilities, and the priority needs to achieve well-identified scientific goals. Several founding events will be organized in 2018 in several African research centers and higher-education institutions to

    In South Africa, a country that is rich in natural resources, gross domestic product has risen steadily since the historic elections in April 1994. In 1995, foreign trade made up almost 50 per cent of the country's gross national product. Unemployment and concurrent shortage of skilled labour are some of the major challenges that still exist for South Africa. Sasol is one of South Africa's top 10 private companies. It was founded in 1950; it supplies 44 per cent of South Africa's liquid fuel needs and produces most of the feedstocks used by the chemical and plastics industries in the country. The company is known for innovative technologies, such as the Sasol Synthol Process. It produces high-quality synthetic fuels such as petrol, diesel, kerosene, gas and furnace oils. The unique Sasol Synthol Process was described. Coal is put under high pressure and high temperature in the presence of steam and oxygen, is converted to crude gas, purified by removing sulfur and is then used in the production of gasoline, diesel and other fuels. The process also yields 120 other chemical products for domestic and international markets. 3 refs., 5 figs

    African American men have among the highest prostate cancer incidence rates in the world yet rates among their African counterparts are unclear. In this paper, we compared reported rates among black men of Sub-Saharan African descent using data from the International Agency for Research on Cancer (IARC) and the National Cancer Institute Surveillance, Epidemiology, and End Results Program for 1973-2007. Although population-based data in Africa are quite limited, the available data from IARC showed that rates among blacks were highest in the East (10.7-38.1 per 100,000 man-years, age-adjusted world standard) and lowest in the West (4.7-19.8). These rates were considerably lower than those of 80.0-195.3 observed among African Americans. Rates in Africa increased over time (1987-2002) and have been comparable to those for distant stage in African Americans. These patterns are likely due to differences between African and African American men in medical care access, screening, registry quality, genetic diversity, and Westernization. Incidence rates in Africa will likely continue to rise with improving economies and increasing Westernization, warranting the need for more high-quality population-based registration to monitor cancer incidence in Africa.

    Like China, a large portion of South Africa's primary energy is sourced from coal, and is likely to remain South Africa's major source of energy for the short to medium term. It is imperative to address the environmental dimension as an integral component of coal energy considerations. This issue is discussed through energy efficiency, and South Africa's Low-Smoke Coal Programme as it pertains to the use of coal in households. South Africa is engaged on several other programmes to minimise the impact of coal on the atmospheric environment. Some of those activities have been outlined in this paper. (R.P.)

  7. The effects of obesity on doctor-diagnosed chronic diseases in Africa: empirical results from Senegal and South Africa.

    Asfaw, Abay

    2006-01-01

    While inadequate food and communicable infectious diseases have been a concern of researchers and policy makers in Africa, little attention has been given to obesity and chronic, non-communicable diseases. Africa is not usually associated with obesity and chronic diseases. Yet there has been a sharp rise in the incidence of obesity and chronic diseases, a major public health problem in many countries. The paper examines the impact of obesity on the prevalence of four doctor-diagnosed chronic diseases in Senegal and South Africa. The results reveal that obese respondents were 4.7, 2.8, and 4.8% more likely to face the risks of arthritis, diabetes, and heart diseases in South Africa and 6.5 and 7.4% more likely to face the risks of heart disease and asthma in Senegal than their lean counterparts. Obesity imposes a real and substantial danger, affecting the prevalence of chronic diseases. Unchecked it can be a major public health problem, impose a serious challenge to the health sector, and can jeopardize future developments.

Os mantidos na maior densidade e alimentados com dietas suplementadas com 0 e 6 mg de cromo kg-1apresentaram redução do número de linfócitos circulantes, sugerindo má adaptação a essa condição de alta densidade. Nas dietas suplementadas com 12 e 18 mg kg-1, tal efeito não foi observado, porém verificou-se aumento do número de trombócitos no tratamento com 12 mg de cromo kg-1. A inexistência de diferença significativa entre os tratamentos, aos 30 dias, sugere a adaptação dos peixes ao tipo de alimento e à situação de alta densidade. Portanto, nas condições deste ensaio, a suplementação com 12 e 18 mg de cromo kg-1 é interessante como estratégia alimentar durante 15 dias.This work evaluated the effects of chromium supplementation on thehematological parameters of Piaractus mesopotamicus Holmberg, 1887 maintained in two stocking densities. Fish were fed diets supplemented with 0, 6, 12 and 18 mg trivalent chromium kg-1 dry ration and maintained at 4 and 20 kg m-3. The fish under high stockingdensity and fed diets supplemented with 0 and 6 mg kg-1 showed reduction in the number lymphocytes, which suggests non-adaptation to this condition of high density. This was not observed in fish fed diets supplemented with 12 and 18 mg chromium kg-1, but an increasein the number of thrombocytes was evident. The lack of difference between treatments after 30 days may suggest a possible adaptation of fish to the situation. It can be added that supplementation with 12 and 18 mg chromium kg-1 is an interesting feeding strategy for aperiod of 15 days.

    Measurement of incidence rates of childhood cancer in Africa is difficult. The study 'Cancer of Childhood in sub Saharan Africa' [Stefan C, Bray F, Ferlay J, Parkin DM and Liu B (2017) Cancer of Childhood in sub-Saharan Africa ecancer 11 (755)] brings together results from 16 population-based registries which, as members of the African Cancer Registry Network (AFCRN), have been evaluated as achieving adequate coverage of their target population. The cancers are classified according to the third revision of the International Classification of Childhood Cancer (ICCC-3) and recorded rates in Africa are compared with those in childhood populations in the UK, France, and the USA. It is clear that, in many centres, lack of adequate diagnostic and treatment facilities, leads to under-diagnosis (and enumeration) of leukaemias and brain cancers. However, for several childhood cancers, incidence rates in Africa are higher than those in high income countries. This applies to infection-related cancers such as Kaposi sarcoma, Burkitt lymphoma, Hodgkin lymphoma and hepatocellular carcinoma, and also to two common embryonal cancers-retinoblastoma and nephroblastoma. These (and other) observations are unlikely to be artefact, and are of considerable interest when considering possible aetiological factors, including ethnic differences in risk (and hence genetic/familial antecedents). The data reported are the most extensive so far available on the incidence of cancer in sub Saharan Africa, and clearly indicate the need for more resources to be devoted to cancer registration, especially in the childhood age range, as part of an overall programme to improve the availability of diagnosis and treatment of this group of cancers, many of which have-potentially-an excellent prognosis.

    Global agriculture has undergone a period of rapid intensification characterized as 'Green Revolution', except for Africa, which is the region most affected by unreliable food access and undernourishment. Increasing crop production will be one of the most challenges and most effectual way to mitigate food insecurity there, as Africa's agricultural yield is on a much lower level comparing to global average. In this study we characterize cropland vegetation phenology in Africa based on MODIS NDVI time series between 2000 and 2012. Cumulated NDVI is a proxy for net primary productivity and used as an indicator for evaluating the potential yield gap in Africa. It is achieved via translating the gap between optimum attainable productivity level in each classification of cropping systems and actual productivity level by the relationship of cumulated NDVI and cereal-equivalent production. The results show most of cropland area in Africa have decreasing trend in cumulated NDVI, distributing in the Nile Delta, Eastern Africa and central of semi-arid to arid savanna area, except significant positive cumulated NDVI trends are mainly found between Senegal and Benin. Using cumulated NDVI and statistics of cereal equivalent production, we find remarkable potential yield gap at the Horn of East Africa (especially in Somalia), Northern Africa (Morocco, Algeria and Tunisia). Meanwhile, countries locating at the savanna area near Sahel desert and South Africa also show significant potential, though they already have a relatively high level of productivity. Our results can help provide policy recommendation for local government or NGO to tackle food security problems by identifying zones with high potential of yield improvement.

    Is epilepsy truly an "African ailment"? We aimed to determine this, since international health agencies often refer to epilepsy as an African disease and the scientific literature has spoken the same tone. Various published materials, mainly reports, articles, were used to gather Asian and African evidence on various aspects of epilepsy and many of its risk and associated factors. Our results suggest that in no way can epilepsy be considered as an African ailment and such characterization is most likely based on popular beliefs rather than scientific evidence. In comparison to Africa, Asia has a 5.0% greater burden from all diseases, and is 17.0% more affected from neuropsychiatric disorders (that include epilepsy). Given that more countries in Asia are transitioning, there may be large demographic and lifestyle changes in the near future. However these changes are nowhere close to those expected in Africa. Moreover, 23 million Asians have epilepsy in comparison to 3.3 million Africans and 1.2 million sub-Saharan Africans. In comparison to Africa, Asia has more untreated patients, 55.0% more additional epilepsy cases every year, because of its larger population, with greater treatment cost and possibly higher premature mortality. Of several associated factors discussed herein, many have more importance for Asia than Africa. The current state of epilepsy in Asia is far less than ideal and there is an urgent need to recognize and accept the importance of epilepsy in Asia. In no way can epilepsy be considered as an African ailment. This is most likely based on popular beliefs rather than scientific evidence.

    The Republic of South Africa lies at the southern tip of the African continent. The population encompasses a variety of races, ethnic groups, religions, and cultural identities. The country has had a turbulent history from early tribal conflicts, colonialisation, the apartheid period, and post-apartheid readjustment. Modern terrorism developed mainly during the apartheid period, both by activities of the state and by the liberation movements that continued to the time of the first democratic elections in 1994, which saw South Africa evolve into a fully representative democratic state with equal rights for all. Since 1994, terrorist acts have been criminal-based, evolving in the Cape Town area to political acts, largely laid at the feet of a predominantly Muslim organisation, People against Gangsterism and Drugs, a vigilant organisation allegedly infiltrated by Muslim fundamentalists. Along with this, has been terrorist activities, mainly bombings by disaffected members of white, right-wing groups. In the apartheid era, a Draconian series of laws was enacted to suppress liberation activities. After 1994, most of these were repealed and new legislation was enacted, particularly after the events of 11 September 2001; this legislation allows the government to act against terrorism within the constraints of a democratic system. Disaster management in South Africa has been largely local authority-based, with input from provincial authorities and Civil Defence. After 1994, attempts were made to improve this situation, and national direction was provided. After 11 September 2001, activity was increased and the Disaster Management Act 2002 was brought into effect. This standardized disaster management system at national, provincial, and local levels, also facilites risk assessment and limitation as well as disaster mitigation. The potential still exists for terrorism, mainly from right-wing and Muslim fundamentalist groups, but the new legislation should stimulate disaster

  16. On the pace of fertility decline in sub-Saharan Africa

    Directory of Open Access Journals (Sweden)

    David Shapiro

    2017-10-01

    Full Text Available Background: This descriptive finding examines the comparative pace of fertility decline in sub-Saharan Africa, relative to Asia, Latin America and the Caribbean, and Northern Africa. Objective: We seek to determine if fertility decline has been slower in sub-Saharan Africa than elsewhere in the developing world. Methods: United Nations 2017 estimates of national fertility are used in assessing the comparative pace of fertility decline, and the four regions are compared in terms of how far they are into their fertility transition. Results: The data shows clearly that fertility decline in sub-Saharan Africa, still at a comparatively early stage, has been considerably slower than the earlier declines in Asia, Latin America and the Caribbean, and Northern Africa at comparable stages of the transition, and displays less within-region heterogeneity than the transitions in these other regions. Conclusions: The slower pace of fertility decline in sub-Saharan Africa, in conjunction with the high current fertility levels in the region, means that in the absence of policies seeking to accelerate fertility decline, sub-Saharan Africa will continue to experience rapid population growth that in turn will constrain its development. Contribution: Presentation of data in a novel way (Figures 2‒4, and associated calculations unambiguously demonstrates the slow pace of fertility decline in sub-Saharan Africa compared with other regions of the world.

    2013-08-01

    Research purpose: This paper investigated the challenges, demands and expectations of Nigerian tourists to South Africa. Motivation for the study: Nigeria, along with other African nations, has been identified as one of the core regional source markets with air links to South Africa. Increasing revenue generated from regional tourism is important to South African Tourism. Research design, approach and method: Descriptive statistics and Chi-square tests were used to analyse the data collected using a questionnaire survey of 320 Nigerian tourists to South Africa. Main findings: Results showed that Nigerian tourists visit South Africa mostly for the purposes of business, holiday, visiting friends and relatives, education and medical care. Challenges perceived by these Nigerian tourists visiting South Africa include long waiting time for the visa process in Nigeria, expensive cost of living in South Africa, safety and security problems, not so many airlines to choose from and expensive flight costs. Nigerian tourists mostly expect South Africans to be friendlier and have expectations of linking up with new business partners or performing transactions. They also have a strong demand for shopping, leisure and quality education. Practical/managerial implications: This study recommends a bilateral tourism relationship agreement between the Nigerian and South African governments to ameliorate the visa process; targeted marketing communications by South African Tourism toward Nigerian tourists based on study results; strong police presence and proper policing in South Africa; air transport liberalisation and low-cost carriers implementation for shared economic growth within the African region. Contribution/value-add: No former research has specifically identified Nigerian tourists’ challenges, expectations and demands whilst visiting South Africa.

    1999-01-01

    In 1950, 28% of the world¿s population lived in cities. At that point, localities larger than 10,000 inhabitants were home to 0.7 billion people, of whom 36% were in developing countries. However, according to UN projections, the rate of urbanization will reach 47.4% in 2000, with cities housing 2.9 billion people, of whom 68.7% will be in developing countries. Africa, like other continents, is urbanizing. Although Africa is among the world¿s least urbanized regions, it is nonetheless the continent with the highest rate of urbanization. Urban population growth reached its height during the 1950s, then the urban population in the region multiplied by a factor of 10 during 1950-90, far outpacing the rate of overall population growth on the continent. However, during the 1980s and 1990s, urban growth in Africa declined sharply. The author discusses urbanization in Africa devoid of industrialization, declining rates of urban population growth in the region, the uncertain future of urbanization in Africa, and how future urbanization in Africa depends upon the role the continent will play in the global economy.

    Marum, L H; Tindyebwa, D; Gibb, D

    1997-01-01

    HIV/AIDS is a major cause of pediatric morbidity and mortality, especially in Africa. The UN Joint Program on HIV/AIDS (UNAIDS) estimates that 85% of the 2.6 million children with HIV infection are from sub-Saharan Africa. About 650,000 children are living with HIV/AIDS and approximately 1000 infected infants are born every day in Africa. Since few of the 7 million infected African women have access to HIV testing and counseling, not to mention interventions such as AZT to reduce the risk of HIV transmission to their infants, the high incidence of HIV-infected children in Africa will likely continue for some time. The countries of east and southern Africa and several countries in west Africa have the highest HIV prevalence rates in the world. The development of cost-effective strategies to provide care and improve the quality of life of HIV-infected infants and children in Africa should be a priority area for increased research and support. The authors describe progress in understanding the natural history of HIV infection in African children, review strategies for managing HIV-infected children in resource-poor settings, and discuss issues of community response and counseling for children.

  4. Water resources for Africa

    International Nuclear Information System (INIS)

    2003-01-01

    Water scarcity is a matter of urgent, national, regional and international concern. For those people, usually women, who are responsible for the daily task of obtaining sufficient water for household use, water shortages are a perpetual worry. It is a situation which affects many individual families and communities throughout the arid and semi-arid regions of Africa. The isotope studies conducted thus far have proved that the majority of regional groundwater systems in northern Africa and the Sahel zone are paleowaters, replenished thousands of years ago, without the possibility of significant replenishment under present climatic conditions. Therefore, removal from such underground reservoirs will eventually deplete the resource. Mapping these paleowaters, and estimating their reservoir sizes, is a priority. (IAEA)

    South Africa was privileged to be part of the MDGs agenda which was adopted in 2000. One of the aims of MDGs was to reduce extreme poverty by half in 2015. For that reason, South Africa integrated policies and strategies to rid poverty by half to that of United Nations (UN).

  7. Plasmodium vivax Transmission in Africa.

    Directory of Open Access Journals (Sweden)

    Rosalind E Howes

    2015-11-01

    Full Text Available Malaria in sub-Saharan Africa has historically been almost exclusively attributed to Plasmodium falciparum (Pf. Current diagnostic and surveillance systems in much of sub-Saharan Africa are not designed to identify or report non-Pf human malaria infections accurately, resulting in a dearth of routine epidemiological data about their significance. The high prevalence of Duffy negativity provided a rationale for excluding the possibility of Plasmodium vivax (Pv transmission. However, review of varied evidence sources including traveller infections, community prevalence surveys, local clinical case reports, entomological and serological studies contradicts this viewpoint. Here, these data reports are weighted in a unified framework to reflect the strength of evidence of indigenous Pv transmission in terms of diagnostic specificity, size of individual reports and corroboration between evidence sources. Direct evidence was reported from 21 of the 47 malaria-endemic countries studied, while 42 countries were attributed with infections of visiting travellers. Overall, moderate to conclusive evidence of transmission was available from 18 countries, distributed across all parts of the continent. Approximately 86.6 million Duffy positive hosts were at risk of infection in Africa in 2015. Analysis of the mechanisms sustaining Pv transmission across this continent of low frequency of susceptible hosts found that reports of Pv prevalence were consistent with transmission being potentially limited to Duffy positive populations. Finally, reports of apparent Duffy-independent transmission are discussed. While Pv is evidently not a major malaria parasite across most of sub-Saharan Africa, the evidence presented here highlights its widespread low-level endemicity. An increased awareness of Pv as a potential malaria parasite, coupled with policy shifts towards species-specific diagnostics and reporting, will allow a robust assessment of the public health

  8. Telerehabilitation In South Africa – Is There A Way Forward?

    2011-05-01

    Full Text Available South Africa, like the rest of sub-Saharan Africa, has a disproportionate burden of disease and a shortage of health professionals. Telemedicine has been identified as a possible way of overcoming part of the problem but telemedicine has not been widely adopted. In the public sector hospitals in South Africa which serve 82% of the population there are 2.5 physiotherapists and 2 occupational therapists per 100,000 people served. The extent of telerehabilitation in South Africa is unknown. A literature review of telerehabilitation found no papers from South Africa. A survey of the heads of university departments of physiotherapy, occupational therapy and speech and language pathology revealed limited knowledge of telerehabilitation. Telerehabilitation services are confined to follow-up of patients at some institutions by telephone, fax or email. There is need to raise awareness among therapists if telerehabilitation is to become a reality in South Africa.  Future actions are outlined.

    2013-01-01

    Telecardiology holds great promise for Africa, from tele-echocardiography and tele-ECG s, to home monitoring and text messaging for medication adherence monitoring. The burden of disease is great and there is an extreme shortage of health professionals. Telemedicine can provide access to scarce specialist care, improve the quality of care in rural areas and reduce the need for rural patients to travel to seek medical attention. International cross border service can alleviate the shortage of doctors. But telecardiology, and telemedicine uptake in general, has been poor in Africa. Legal and ethical issues around local and cross border telemedicine have not been resolved. The literature was reviewed and obstacles to telemedicine in Africa and current telemedicine activities in Africa, are described. There are few sustained telemedicine services in Africa with the exception of tele-education. There is an expectation that mobile phones will facilitate a range of telemedicine activities in Africa. Africa needs telemedicine. © 2013.

    2007-09-01

    Full Text Available The epidemiology of serotype SAT-2 foot-and-mouth disease was investigated in sub-Saharan Africa by phylogenetic analysis using the 1D gene encoding the major antigenic determinant. Fourteen genotypes were identified of which three are novel and belong to East Africa, bringing the total number of genotypes for that region to eight. The genotypes clustered into three lineages that demonstrated surprising links between East, southern and south-western Africa. One lineage was unique to West Africa. These results established numerous incursions across country borders in East Africa and long term conservation of sequences for periods up to 41 years. Ethiopia, Kenya and Uganda have all experienced outbreaks from more than one unrelated strain, demonstrating the potential for new introductions. The amount of variation observed within this serotype nearly equalled that which was found between serotypes; this has severe implications for disease control using vaccination.

    South Africa is a country in the midst of transformation. Political changes within the country, and the ensuing empowerment of the black majority, have created a situation where dramatic improvements are needed in the country's infrastructure in order to enable it to meet the needs of all its people over the coming decades. Largely as a result of the international embargo placed on South Africa during the apartheid era, the South African government became heavily involved in the country's energy sector. This involvement included development of a synfuels program, price controls in the oil sector, monopolies in both upstream and downstream oil sectors, and a strong centralized electric power company. In 1994, South Africa became the eleventh member of the Southern Africa Development Community (SADC), an organization which was established in 1980 to synchronize development plans for its member countries. SADC is presently working to formulate a regional energy development plan, and coordinate technical information exchanges and joint research needs. Each of the SADC nations have also begun to develop their regional electricity grids and other parts of their energy infrastructure to plan for the growing needs of the 500 million people who live in sub-Saharan Africa. South Africa, in particular, must make significant changes in each of its energy sectors in the near future, to keep up with its growing energy requirements.

    Highlights: Black-Right-Pointing-Pointer This is a compendium on GHG reductions via improved waste strategies in Africa. Black-Right-Pointing-Pointer This note provides a strategic framework for Local Authorities in Africa. Black-Right-Pointing-Pointer Assists LAs to select Zero Waste scenarios and achieve sustained GHG reduction. - Abstract: Only few Clean Development Mechanism (CDM) projects (traditionally focussed on landfill gas combustion) have been registered in Africa if compared to similar developing countries. The waste hierarchy adopted by many African countries clearly shows that waste recycling and composting projects are generally the most sustainable. This paper undertakes a sustainability assessment for practical waste treatment and disposal scenarios for Africa and makes recommendations for consideration. The appraisal in this paper demonstrates that mechanical biological treatment of waste becomes more financially attractive if established through the CDM process. Waste will continue to be dumped in Africa with increasing greenhouse gas emissions produced, unless industrialised countries (Annex 1) fund carbon emission reduction schemes through a replacement to the Kyoto Protocol. Such a replacement should calculate all of the direct and indirect carbon emission savings and seek to promote public-private partnerships through a concerted support of the informal sector.

    Full Text Available Background Tobacco use prevalence in Africa is projected to rise over the next 15 years without stronger tobacco control measures. However, little research details the scope of tobacco control research being conducted in Africa. A systematic literature review was conducted to better understand the landscape of tobacco control efforts in Africa. Methods A literature search of tobacco research conducted in all African countries from 1996 to 2016 was performed in PubMed, Embase, and African Index Medicus. Published abstracts meeting the inclusion criteria of focusing on nicotine or tobacco product(s and having been conducted in one or more African countries were selected for full coding and analysis. The authors coded on study characteristics such as type of research, tobacco product, and country. Three coders double-coded 5% of the articles reviewed to ensure agreement. Results This review found 645 relevant articles, in French and English, representing 52 African countries. South Africa was the focus of the greatest proportion of these published tobacco control research articles (23%, followed by Nigeria (17%, Egypt (13%, and Tunisia (12%. Reporting the prevalence of tobacco use was the focus of 51% of these articles. Other areas of research included the potential determinants of tobacco use (28%; knowledge, attitudes, and beliefs about tobacco products or policies (26%; and biological consequences of tobacco use (25%. Most studies (63% discussed cigarettes, and 15% studied smokeless tobacco. Youth-targeted studies comprised 25% of all research in Africa. Publications per year increased between 1996 and 2015, quadrupling in number by 2015. Conclusions A comprehensive review of the literature provides a baseline understanding of the tobacco control landscape and the increased attention countries are showing to tobacco and tobacco control. This research may inform opportunities for further research and for strengthening networks and thereby the

  17. Quantitative maps of groundwater resources in Africa

    2012-01-01

    In Africa, groundwater is the major source of drinking water and its use for irrigation is forecast to increase substantially to combat growing food insecurity. Despite this, there is little quantitative information on groundwater resources in Africa, and groundwater storage is consequently omitted from assessments of freshwater availability. Here we present the first quantitative continent-wide maps of aquifer storage and potential borehole yields in Africa based on an extensive review of available maps, publications and data. We estimate total groundwater storage in Africa to be 0.66 million km 3 (0.36–1.75 million km 3 ). Not all of this groundwater storage is available for abstraction, but the estimated volume is more than 100 times estimates of annual renewable freshwater resources on Africa. Groundwater resources are unevenly distributed: the largest groundwater volumes are found in the large sedimentary aquifers in the North African countries Libya, Algeria, Egypt and Sudan. Nevertheless, for many African countries appropriately sited and constructed boreholes can support handpump abstraction (yields of 0.1–0.3 l s −1 ), and contain sufficient storage to sustain abstraction through inter-annual variations in recharge. The maps show further that the potential for higher yielding boreholes ( > 5 l s −1 ) is much more limited. Therefore, strategies for increasing irrigation or supplying water to rapidly urbanizing cities that are predicated on the widespread drilling of high yielding boreholes are likely to be unsuccessful. As groundwater is the largest and most widely distributed store of freshwater in Africa, the quantitative maps are intended to lead to more realistic assessments of water security and water stress, and to promote a more quantitative approach to mapping of groundwater resources at national and regional level.

    Dihydroartemisinin/piperaquine (DHA/PPQ) is increasingly deployed as antimalaria drug in Africa. We report the detection in Mali of Plasmodium falciparum infections carrying plasmepsin 2 duplications (associated with piperaquine resistance) in 7/65 recurrent infections within 2 months after DHA/PPQ treatment. These findings raise concerns about the long-term efficacy of DHA/PPQ treatment in Africa.

    This report is the first publication produced within the framework of the WEC's Africa Regional Action Plan as part of the 2005-2007 Work Programme. Presently, over 80% of the total energy consumption in Africa is based on traditional biomass used mostly for cooking. This lack of access to modern energy is holding back economic and social development for 1.6 billion people around the world. The situation is particularly grave in sub-Sahara Africa where over 80% of the population lives in rural areas and the average electrification rate is less than 5%. At least 50 million new connections are needed to provide electricity to supply the non-connected areas in Africa. The over 700 million potential customers represented by these new connections provide a major business opportunity. It is now widely recognised that development assistance, bilateral aid, multilateral financing institutions, a multitude of international aid agencies, NGOs and others have failed to make a significant difference. A new approach is required, otherwise the number of people without access to electricity will continue to grow, and none of the Millennium Development Goals set by the United Nations will be achieved. This regional report highlights key factors that affect cooperative energy projects. The geopolitical context, investment climate and appropriate regulation are just as important as the institutional and technical capacity required to execute many of these projects. The report identifies four key benefits of regional integration: improved security of supply and accessibility; increased economic efficiency; enhanced environmental quality and broader development of renewable resources.

    The purpose of this study was to estimate the economic burden of violence against children in South Africa. We assembled summative estimates of lifetime prevalence, calculated the magnitude of associations with negative outcomes, and thereby estimated the economic burden of violence against children. According to our calculations, 2.3 million and 84,287 disability-adjusted life-years (DALYs) lost in South Africa in 2015 were attributable to nonfatal and fatal violence against children, respectively. The estimated economic value of DALYs lost to violence against children (including both fatal and nonfatal) in South Africa in 2015 totalled ZAR173 billion (US $13.5 billion)-or 4.3% of South Africa's gross domestic product (GDP) in 2015. In addition, the reduced earnings attributable to childhood physical violence and emotional violence in South Africa in 2015 were ZAR25.2 billion (US $2.0 billion) and ZAR9.6 billion (US $750 million), respectively. In addition, South Africa spent ZAR1.6 billion (US $124 million) on child care and protection in fiscal year 2015/2016, many of which costs are directly related to violence against children. This study confirms the importance of prioritising violence against children as a key social and economic concern for South Africa's future.

    The history, sources, mineralogy, extraction metallurgy, conversion, and enrichment of uranium in South Africa is reviewed. Over the past 40 years extraction plants were built at 27 sites, and over 140 kt of uranium have been produced. Older plants have had to adapt to changing market conditions, no single technology has had the opportunity to become entrenched, and the costs have been reduced to a third of those of the original flowsheet. The research efforts aimed at developing the country's nuclear raw materials have been particularly rewarding, as they have enabled South Africa to become a world leader in the extraction of uranium from low-grade ores and to develop methods for uranium enrichment and the production of nuclear fuels. 43 refs., 7 figs., 4 tabs

    Current and future carbon emissions from land-use change and energy consumption were analyzed for Sub-Saharan Africa. The energy sector analysis was based on UN energy data tapes while the land-use analysis was based on a spatially-explicit land-use model developed specifically for this project. The impacts of different energy and land-use strategies on future carbon emissions were considered. (A review of anthropogenic emissions of methane, nitrous oxides, and chlorofluorocarbons in Sub-Saharan Africa indicated that they were probably minor in both a global and a regional context. The study therefore was focused on emissions of carbon dioxide.) The land-use model predicts carbon emissions from land use change and the amount of carbon stored in vegetation (carbon inventory) on a yearly basis between 1985 and 2001. Emissions and inventory are modeled at 9000 regularly-spaced point locations in Sub-Saharan Africa using location-specific information on vegetation type, soils, climate and deforestation. Vegetation, soils, and climate information were derived from continental-scale maps while relative deforestation rates(% of forest land lost each year) were developed from country-specific forest and deforestation statistics (FAO Tropical Forest Resources Assessment for Africa, 1980). The carbon emissions under different land use strategies in Sub-Saharan Africa were analyzed by modifying deforestation rates and altering the amount of carbon stored under different land uses. The considered strategies were: preservation of existing forests, implementation of agroforestry, and establishment of industrial tree plantations. 82 refs., 16 figs., 25 tabs.

    It is suggested that many industries in Africa could benefit from biomass-fired cogeneration so long as the correct structures and learning processes are put in place. The article discusses Africa's energy background and gives figures for generation sources and consumption. A profile of Sudan and its energy needs is presented. It is argued that although some barriers do exist, a move to cogeneration is essential. CHP should be particularly attractive for industries able to use thermal energy for drying, heating and cooling: typical areas would be pharmaceutical and chemical plants, textile factories, cement works and steel mills

    There have been extensive developments in the power supply industry in South Africa. The most evident of these has been the increase in the size of generating units. Escom has recently placed orders for 600 MW units. In South Africa, with its large indigenous reserves of cheap coal, there was no need to rush into a nuclear power programme before it would be economic and, accordingly the first serious study of nuclear power generation was not undertaken until 1966. A final aspect of power generation which is becoming very important is the control of pollution and protection of the environment

    Vector-borne diseases are caused by parasites, bacteria, or viruses transmitted by the bites of hematophagous arthropods. In Africa, there has been a recent emergence of new diseases and the re-emergence of existing diseases, usually with changes in disease epidemiology (e.g., geographical distribution, prevalence, and pathogenicity). In Africa, rickettsioses are recognized as important emerging vector-borne infections in humans. Rickettsial diseases are transmitted by different types of arthropods, ticks, fleas, lice, and mites. This review will examine the roles of these different arthropod vectors and their geographical distributions. Copyright © 2012 Elsevier GmbH. All rights reserved.

    There is limited information about the challenges of cancer management and attempts at improving outcomes in Africa. Even though South and North Africa are better resourceds to tackle the burden of breast cancer, similar poor prognostic factors are common to all countries. The five-year overall Survival rate for breast cancer patients does not exceed 60% for any low and middle-income country (LMIC) in Africa. In spite of the gains achieved over the past decade, certain characteristics remain the same such as limited availability of breast conservation therapies, inadequate access to drugs, few oncology specialists and adherence to harmful socio-cultural practices. This review on managing breast cancer in Africa is authored by African oncologists who practice or collaborate in Africa and with hands-on experience with the realities. A search was performed via electronic databases from 1999 to 2016. (PubMed/Medline, African Journals Online) for all literature in English or translated into English, covering the terms "breast cancer in Africa and developing countries". One hundred ninety were deemed appropriate. Breast tumors are diagnosed at earlier ages and later stages than in highincome countries. There is a higher prevalence of triple-negative cancers. The limitations of poor nursing care and surgery, inadequate access to radiotherapy, poor availability of basic and modern systemic therapies translate into lower survival rate. Positive strides in breast cancer management in Africa include increased adaptation of treatment guidelines, improved pathology services including immuno-histochemistry, expansion and upgrading of radiotherapy equipment across the continent in addition to more research opportunities. This review is an update of the management of breast cancer in Africa, taking a look at the epidemiology, pathology, management resources, outcomes, research and limitations in Africa from the perspective of oncologists with local experience.

  20. Cancer prevention in Africa: a review of the literature.

    Science.gov (United States)

    Busolo, David S; Woodgate, Roberta L

    2015-06-01

    Cancer is an emerging crisis in Africa. Cancer was the seventh leading cause of death in 2004. If not controlled, cancer incidence in Africa is expected to reach 1.28 million cases annually and claim 970,000 lives yearly by 2030. This paper presents a review of the literature on current cancer prevention approaches in Africa, and consists of cancer prevention studies conducted in African countries (e.g. South Africa and Nigeria) from PubMed, Scopus, and CINAHL databases. Common female cancers in Africa are breast and cervical cancer while prostate cancer is the most common neoplasm among African males. Other common cancers are liver, colorectal, and non-Hodgkin's lymphoma. Mortality related to these cancers comes as a result of delays in screening and treatment, unfamiliarity with cancer and cancer prevention, inaccessibility and unaffordability of care, and inefficiency of healthcare systems. Cancer prevention efforts are deficient because many governments lack cancer prevention and control policies. Also contributing to the lack of cancer prevention and control policies are low levels of awareness, scarce human and financial resources, and inadequacy of cancer registries. Overall, governments grapple with limited funds and competing healthcare priorities. As cancer continues to increase in Africa, the need for rigorous interdisciplinary research on cancer etiology and monitoring in Africa has never been timelier. Cost-effective cancer prevention programs, coordination of donor funding, advocacy, and education should be aggressively pursued. The call for more collaborative approaches in research and policy is urgently needed. © The Author(s) 2014.

    Given the importance of Africa to studies of human origins and disease susceptibility, detailed characterization of African genetic diversity is needed. The African Genome Variation Project provides a resource with which to design, implement and interpret genomic studies in sub-Saharan Africa and worldwide. The African Genome Variation Project represents dense genotypes from 1,481 individuals and whole-genome sequences from 320 individuals across sub-Saharan Africa. Using this resource, we find novel evidence of complex, regionally distinct hunter-gatherer and Eurasian admixture across sub-Saharan Africa. We identify new loci under selection, including loci related to malaria susceptibility and hypertension. We show that modern imputation panels (sets of reference genotypes from which unobserved or missing genotypes in study sets can be inferred) can identify association signals at highly differentiated loci across populations in sub-Saharan Africa. Using whole-genome sequencing, we demonstrate further improvements in imputation accuracy, strengthening the case for large-scale sequencing efforts of diverse African haplotypes. Finally, we present an efficient genotype array design capturing common genetic variation in Africa.

    To analyze the discourse right construction of China's medical aid to Africa, so as to provide evidences for improving the effect and sustainable development of China's medical aid to Africa. The documents of the discourse right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects, namely confident, charismatic, influential, and dominant. China's medical team made much in the discourse right construction in their aid to Africa, but some China's medical team members were still too cautious and too low-key. China's medical team gained the trust of the people of Africa, but the language communication difficulties still hampered in China's medical aid to Africa. Chinese medical team were widely praised by the African society, but in the west, some African media, even China's media still neglected to report China's doctors. China's international discourse right were greatly improved, but western countries still dominated the public opinion. China should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available In Lost Ground, Michiel Heyns portrays the former white settlers’ position and experience in South Africa, Africa and Europe after the overturn of South Africa’s apartheid regime. An analysis of the novel illustrates that the legacy of the colonisation of Africa and apartheid in South Africa still shapes the settler descendants’ perception of self and the other and the formers’ place in South Africa and Africa. After the electoral victory of the African National Congress, contemporary white South African men, as exemplified by the English-speaking male protagonist who features in the novel, tend to dissociate themselves from the country and the African continent as home. Although the original colonisers’ experience of alienation and ambivalence about apartheid has been widely depicted, the significance of this experience in relation to white South African male identity has not been fully explored in a study of Heyns’s Lost Ground, principally as regards the novel’s detective narrative framework and the counterdiscursive technique of intertextual referencing that implies other interpretative possibilities. Lost Ground will be critically analysed in terms of the central character’s experience of space and place, and the influence of these paradigms on Peter Jacobs as he makes strides towards abandoning historical/racial restrictions and locating his identity in people.

    Background Plague is a rapidly progressing, serious illness in humans that is likely to be fatal if not treated. It remains a public health threat, especially in sub-Saharan Africa. In spite of plague's highly focal nature, a thorough ecological understanding of the general distribution pattern...... of plague across sub-Saharan Africa has not been established to date. In this study, we used human plague data from sub-Saharan Africa for 1970-2007 in an ecological niche modeling framework to explore the potential geographic distribution of plague and its ecological requirements across Africa.

    2015-11-01

    Although South Africa has evolved greatly in the 20 years since the end of apartheid, it remains a very divided country. The highest-performing students are comparable in ability to those in the US and Europe, but nearly all of these students are from priveleged Afrikaaner (European) backgrounds. The vast majority of students in the country are native African, and school standards remain very low across the country. It is common that students have no textbooks, teachers have only a high school education, and schools have no telephones and no toilets. By high school graduation, the majority of students have never used a web browser -- even students in the capital of Johannesburg. And while a few students are inspired by home-grown world-class projects such as the Square Kilometer Array (SKA) and Southern African Large Telescope (SALT), most remain unaware of their existence.Despite the poor state of education in the country, students work hard, are curious, and desire information from the outside world. Astronomy is one subject in which students in rural Africa often show exceptional interest. Perhaps astronomy serves as a 'gateway science,' linking the physically observable world with the exotic and unknown.Here I report on many visits I have made to both rural and urban schools in South Africa during the 2013-2015 period. I have interacted with thousands of grade 7-12 students at dozens of schools, as well as taught students who graduated from this system and enrolled in local universities. I will present an assessment of the state of science education in South Africa, as well as a few broader suggestions for how scientists and educators in developed countries can best make an impact in Southern Africa.

  10. Norovirus Epidemiology in Africa: A Review.

    Directory of Open Access Journals (Sweden)

    Janet Mans

    Full Text Available Norovirus (NoV is recognised as a leading cause of gastroenteritis worldwide across all age groups. The prevalence and diversity of NoVs in many African countries is still unknown, although early sero-prevalence studies indicated widespread early infection. Reports on NoVs in Africa vary widely in terms of study duration, population groups and size, inclusion of asymptomatic controls, as well as genotyping information. This review provides an estimate of NoV prevalence and distribution of genotypes of NoVs in Africa. Inclusion criteria for the review were study duration of at least 6 months, population size of >50 and diagnosis by RT-PCR. As regions used for genotyping varied, or genotyping was not always performed, this was not considered as an inclusion criteria. A literature search containing the terms norovirus+Africa yielded 74 publications. Of these 19 studies from 14 out of the 54 countries in Africa met the inclusion criteria. Data from studies not meeting the inclusion criteria, based on sample size or short duration, were included as discussion points. The majority of studies published focused on children, under five years of age, hospitalised with acute gastroenteritis. The mean overall prevalence was 13.5% (range 0.8-25.5% in children with gastroenteritis and 9.7% (range 7-31% in asymptomatic controls, where tested. NoV GII.4 was the predominant genotype identified in most of the studies that presented genotyping data. Other prevalent genotypes detected included GII.3 and GII.6. In conclusion, NoV is a common pathogen in children with diarrhoea in Africa, with considerable carriage in asymptomatic children. There is however, a paucity of data on NoV infection in adults.

    2010-11-01

    To review prevalence, causes and management of end-stage renal disease (ESRD) in sub-Saharan Africa (SSA). Review of literature and data. Approximately 70% of the least developed countries of the world are in SSA. Rapid urbanization is occurring in many parts of the continent, contributing to overcrowding and poverty. While infections and parasitic diseases are still the leading cause of death in Africa, non-communicable diseases are coming to the forefront. There is a continuing "brain drain" of healthcare workers (physicians and nurses) from Africa to more affluent regions. There are large rural areas of Africa that have no health professionals to serve these populations. There are no nephrologists in many parts of SSA; the numbers vary from 0.5 per million population (pmp) in Kenya to 0.6 pmp in Nigeria, 0.7 pmp in Sudan and 1.1 pmp in South Africa. Chronic kidney disease affects mainly young adults aged 20 - 50 years in SSA and is primarily due to hypertension and glomerular diseases. HIV- related glomerular disease often presents late, with patients requiring dialysis. Diabetes mellitus affects 9.4 million people in Africa. The prevalence of diabetic nephropathy is estimated to be 6 - 16% in SSA. The current dialysis treatment rate is Africa, Nigeria, Mauritius and Ghana, with most of the transplants being living donor transplants, except in South Africa where the majority are from deceased donors. Chronic kidney disease care is especially challenging in SSA, with large numbers of ESRD patients, inadequate facilities, funding and support.

  20. Energy Relations between the European Union and North Africa

    Directory of Open Access Journals (Sweden)

    Sarah Kilpeläinen

    2013-06-01

    Full Text Available This article discusses European Union (EU-North Africa energy relations with a special focus on renewables in North Africa, arguing that the research so far has not taken due account of North African perceptions of EU external energy policy. It is argued that current research on EU-North African relations has not taken sufficient note of the multidimensionality of energy or addressed the inconsistent nature of EU policy making. However, addressing these issues is vital in approaching EU-North Africa energy relations and EU policy towards North Africa in general. The study of perceptions is introduced as one way to develop research further, to give further impetus on understanding how EU-North African energy relations develop and to understand energy relations in their complexity.

  1. Uranium occurrences in the surficial deposits of Southern Africa

    International Nuclear Information System (INIS)

    Hambleton-Jones, B.B.

    1982-01-01

    This paper outlines the geology of the Tertiary to Recent(10 to 0,1 Ma) surficial uranium deposits in South West Africa/Namibia and South Africa. They occur mainly in the Namib Desert to the east of Walvis Bay in South West Africa/Namibia and in the north-western Cape Province of South Africa. All the deposits can be classified as fluviatile, lacustrine/pan, or pedogenic types. The economic potential of the surficial uranium deposits in the north-western Cape is insignificant compared with their South West African/Namibian counterparts. Most of the deposits occur in gypsiferous fluviatile gravels and lacustrine/pan sediments. The largest of the deposits is a lacustrinal, peat-rich, diatomaceous earth type. The mechanisms for the precipitation of the uranium are discussed

  2. Uraniferous surficial deposits in Southern Africa

    International Nuclear Information System (INIS)

    Hambleton-Jones, B.B.; Levin, M.; Wagener, G.F.

    1986-01-01

    Surficial uranium deposits are located in the north-western Cape Province of South Africa, in the Namib Desert east of Walvis Bay in South West Africa/Namibia and in the Serule Block of Botswana. They have been classified into the valley-fill, lacustrine, and pedogenic types. Carnotite is the main uranium-bearing mineral in the larger surficial deposits, with other minerals such as soddyite and phosphuranylite occurring locally. Uraninite or urano-organic complexes occur in the reducing environments of the diatomaceous earth, peat-rich deposits. Economically, the valley-fill type is the most important, with the largest deposits occurring in South West Africa/Namibia. In South West Africa/Namibia the valley-fill surficial uranium deposits occur in the Tumas and Langer Heinrich formations of the Teriary to Recent Namib Group. The Tubas, Langer Heinrich, and Welwitchia deposits are discussed: in them, carnotite occurs in calcareous and gypsiferous fluvial gravels. The pedogenic deposit at Mile 72 occurs in weathered granite and overlying gypcrete and has little economic potential. The economic potential of the surficial deposits in the north-western Cape Province is very limited in comparison with their South West African/Namibian counterparts, but the most important deposits are the lacustrine type, in particular those containing peat and diatomaceous earth. The mechanisms for the precipitation and preservation of the uranium are discussed

  4. Early Back-to-Africa Migration into the Horn of Africa

    Science.gov (United States)

    Hodgson, Jason A.; Mulligan, Connie J.; Al-Meeri, Ali; Raaum, Ryan L.

    2014-01-01

    Genetic studies have identified substantial non-African admixture in the Horn of Africa (HOA). In the most recent genomic studies, this non-African ancestry has been attributed to admixture with Middle Eastern populations during the last few thousand years. However, mitochondrial and Y chromosome data are suggestive of earlier episodes of admixture. To investigate this further, we generated new genome-wide SNP data for a Yemeni population sample and merged these new data with published genome-wide genetic data from the HOA and a broad selection of surrounding populations. We used multidimensional scaling and ADMIXTURE methods in an exploratory data analysis to develop hypotheses on admixture and population structure in HOA populations. These analyses suggested that there might be distinct, differentiated African and non-African ancestries in the HOA. After partitioning the SNP data into African and non-African origin chromosome segments, we found support for a distinct African (Ethiopic) ancestry and a distinct non-African (Ethio-Somali) ancestry in HOA populations. The African Ethiopic ancestry is tightly restricted to HOA populations and likely represents an autochthonous HOA population. The non-African ancestry in the HOA, which is primarily attributed to a novel Ethio-Somali inferred ancestry component, is significantly differentiated from all neighboring non-African ancestries in North Africa, the Levant, and Arabia. The Ethio-Somali ancestry is found in all admixed HOA ethnic groups, shows little inter-individual variance within these ethnic groups, is estimated to have diverged from all other non-African ancestries by at least 23 ka, and does not carry the unique Arabian lactase persistence allele that arose about 4 ka. Taking into account published mitochondrial, Y chromosome, paleoclimate, and archaeological data, we find that the time of the Ethio-Somali back-to-Africa migration is most likely pre-agricultural.

  5. Population growth and food supply in sub-Saharan Africa.

    Science.gov (United States)

    Meerman, J; Cochrane, S H

    1982-09-01

    It is argued in this article that sub-Saharan Africa, given its present institutions and endowments of capital and technology, is already dangerously close to overpopulation. The rapid growth of its population projected for the next decades will greatly increase human misery and depress economic development. Specifically, rapid population growth will have disastrous effects on the region's ability to increase exports and provide people with food. There must be a search for new ways in which these effects could be mitigated. In sub-Saharan Africa fertility either continues to be very high or is increasing, in part due to some decline in traditional practices that reduce fertility, such as prolonged breastfeeding. This situation and the expectation of declining mortality imply that African population growth may increase further. Currently, population in sub-Saharan Africa is about half that of India and a third of China. There are 2 main reasons why reduced fertility in the next few decades is unlikely in sub-Saharan Africa as a whole: Africa has low literacy, high infant and child mortality, and low urbanization; and average African fertility rates may even increase for the next 20 years or so. The question that arises is what are the implications of continuing and rapid population growth for the African food supply. The region's cereal production is largely restricted to 4 grains, i.e., millet, sorghum, maize, and rice. The volume of grain production is less, by weight, than 60% of the production of roots and tubers. There are 2 main differences between the output of these crops in sub-Saharan Africa and the rest of the world: yields/hectare are lower in Africa than in elsewhere; and yields have generally been decreasing or largely constant in Africa. The low productivity has several causes. Today, population pressure has brought diminishing returns to traditional agriculture in much of the Sahel and the savanna, in parts of East Africa, Southern Africa, and parts

  9. Histoplasmosis in Africa: An emerging or a neglected disease?

    Science.gov (United States)

    2018-01-01

    Histoplasmosis in Africa has markedly increased since the advent of the HIV/AIDS epidemic but is under-recognised. Pulmonary histoplasmosis may be misdiagnosed as tuberculosis (TB). In the last six decades (1952–2017), 470 cases of histoplasmosis have been reported. HIV-infected patients accounted for 38% (178) of the cases. West Africa had the highest number of recorded cases with 179; the majority (162 cases) were caused by Histoplasma capsulatum var. dubuosii (Hcd). From the Southern African region, 150 cases have been reported, and the majority (119) were caused by H. capsulatum var. capsulatum (Hcc). There have been 12 histoplasmin skin test surveys with rates of 0% to 35% positivity. Most cases of Hcd presented as localised lesions in immunocompetent persons; however, it was disseminated in AIDS patients. Rapid diagnosis of histoplasmosis in Africa is only currently possible using microscopy; antigen testing and PCR are not available in most of Africa. Treatment requires amphotericin B and itraconazole, both of which are not licensed or available in several parts of Africa. PMID:29346384

  10. “The same love, the same faith, the same tears”: ecclesial initiatives about the cult of Our Lady of El Quinche to defend the Republic of the Sacred Heart, Ecuador (1883-1889

    2017-07-01

    Full Text Available Within the conflict between church and state in the 19th century, the clergy and laymen tried to defend the establishment where the church had hegemony over the state and society. Between 1883 and 1889, Ecuador experienced some ecclesial initiatives to defend which stood for the idea of a Republic of the Sacred Heart. This article studies the case of Our Lady of El Quiche, a colonial massive cult, which was part of a process of re-appropriation and reinterpretation of its history. It also suffered a process of spreading and strengthening of its cult, linking with the image of the Republic, political conflicts and the power of the church. Between politics and religion, the discourses and practices of the clergy and the faithful show the intention of the church to shore up its own idea of a catholic Republic and an organized society. In this article, the use of manuscripts and printed sources give information to contrast multiple voices and multiple religious acts which performed a new local Mariology about El Quinche and a reaction to a context in which the religious hegemony and the participation of the clergy in politics were questioned; meanwhile the relations inside the church were recomposing.

  12. Mitochondrial lineage M1 traces an early human backflow to Africa.

    The out of Africa hypothesis has gained generalized consensus. However, many specific questions remain unsettled. To know whether the two M and N macrohaplogroups that colonized Eurasia were already present in Africa before the exit is puzzling. It has been proposed that the east African clade M1 supports a single origin of haplogroup M in Africa. To test the validity of that hypothesis, the phylogeographic analysis of 13 complete mitochondrial DNA (mtDNA) sequences and 261 partial sequences belonging to haplogroup M1 was carried out. The coalescence age of the African haplogroup M1 is younger than those for other M Asiatic clades. In contradiction to the hypothesis of an eastern Africa origin for modern human expansions out of Africa, the most ancestral M1 lineages have been found in Northwest Africa and in the Near East, instead of in East Africa. The M1 geographic distribution and the relative ages of its different subclades clearly correlate with those of haplogroup U6, for which an Eurasian ancestor has been demonstrated. This study provides evidence that M1, or its ancestor, had an Asiatic origin. The earliest M1 expansion into Africa occurred in northwestern instead of eastern areas; this early spread reached the Iberian Peninsula even affecting the Basques. The majority of the M1a lineages found outside and inside Africa had a more recent eastern Africa origin. Both western and eastern M1 lineages participated in the Neolithic colonization of the Sahara. The striking parallelism between subclade ages and geographic distribution of M1 and its North African U6 counterpart strongly reinforces this scenario. Finally, a relevant fraction of M1a lineages present today in the European Continent and nearby islands possibly had a Jewish instead of the commonly proposed Arab/Berber maternal ascendance.

    Agricultural production in West Africa is highly vulnerable to climate variability and change and a fast growing demand for food adds yet another challenge. Assessing possible adaptation strategies of crop production in West Africa under climate change is thus critical for ensuring regional food security and improving human welfare. Our previous efforts have identified as the main features of climate change in West Africa a robust increase in temperature and a complex shift in the rainfall pattern (i.e. seasonality delay and total amount change). Unaddressed, these robust climate changes would reduce regional crop production by up to 20%. In the current work, we use two well-validated crop models (APSIM and SARRA-H) to comprehensively assess different crop adaptation options under future climate scenarios. Particularly, we assess adaptations in both the choice of crop types and management strategies. The expected outcome of this study is to provide West Africa with region-specific adaptation recommendations that take into account both climate variability and climate change.

    There is exponential growth in the interest and implementation of genomics research in Africa. This growth has been facilitated by the Human Hereditary and Health in Africa (H3Africa) initiative, which aims to promote a contemporary research approach to the study of genomics and environmental determinants of common diseases in African populations. The purpose of this article is to describe important challenges affecting genomics research implementation in Africa. The observations, challenges and recommendations presented in this article were obtained through discussions by African scientists at teleconferences and face-to-face meetings, seminars at consortium conferences and in-depth individual discussions. Challenges affecting genomics research implementation in Africa, which are related to limited resources include ill-equipped facilities, poor accessibility to research centers, lack of expertise and an enabling environment for research activities in local hospitals. Challenges related to the research study include delayed funding, extensive procedures and interventions requiring multiple visits, delays setting up research teams and insufficient staff training, language barriers and an underappreciation of cultural norms. While many African countries are struggling to initiate genomics projects, others have set up genomics research facilities that meet international standards. The lessons learned in implementing successful genomics projects in Africa are recommended as strategies to overcome these challenges. These recommendations may guide the development and application of new research programs in low-resource settings.

    We review recent published data on demographics, causes, diagnoses, treatment, and outcome of acute kidney injury (AKI) in Africa. A review of the incidence, etiology, diagnoses, and treatment of AKI in adults in Africa from studies published between the years 2000 and 2015. The incidence of AKI in hospitalized patients in Africa ranges from 0.3 to 1.9% in adults. Between 70 and 90% of cases of AKI are community acquired. Most patients with AKI are young with a weighted mean age of 41.3 standard deviation (SD) 9.3 years, and a male to female ratio of 1.2 : 1.0. Medical causes account for between 65 and 80% of causes of AKI. This is followed by obstetric causes in 5 - 27% of cases and surgical causes in 2 - 24% of cases. In the reported studies, between 17 and 94% of patients who needed dialysis received this. The mortality of AKI in adults in Africa ranged from 11.5 to 43.5%. Most reported cases of AKI in Africa originate in the community. The low incidence of hospital-acquired AKI is likely to be due to under ascertainment. Most patients with AKI in Africa are young and have a single precipitating cause. Prominent among these are infection, pregnancy complications and nephrotoxins. Early treatment can improve clinical outcomes.

    Full Text Available Corruption in South Africa includes the private use of public resources, bribery and improper favouritism. South Africa scored 45 points out of 100 on the 2016 Corruption Perceptions Index reported by Transparency International. Corruption Index in South Africa averaged 46.97 Points from 1996 until 2016, reaching an all-time high of 56.80 Points in 1996 and a record low of 41 Points in 2011. A tenderpreneur is common corruption in South Africa. It is an individual who enriches themselves through corrupting the awarding of government tender contracts, mostly based on personal connections and corrupt relationships - although outright bribery might also take place - and sometimes involving an elected or politically appointed official (or his or her family members holding simultaneous business interests. This is often accompanied by overcharging and shoddy workmanship.

    Full Text Available Water resources, particularly in arid and semi-arid regions of the world are of great concern, as they are closely linked to the wellbeing of humankind. Sophisticated hydrological prediction tools are required to assess climatic and hydrometeorological conditions, as they impact the sustainability of water resources as well as water availability. Research and data collection activities from multi-hydrometeorological sensors (e.g., gauges, radars, satellites form the basis for quantifying the impact of extreme episodes along the hydrologic phases that manifest in terms of the magnitude, duration and frequency of floods, droughts and other hydrometeorological hazards that affect water resources management. A number of hydrometeorological research activities have been reported in the literature by various researchers and research groups globally. This contribution presents (a a review of the hydrometeorology resource landscape in South Africa; (b an analysis of the hydrometeorology services and products in South Africa; (c a review of the hydrometeorological research that has been conducted in South Africa for the last four decades; and (d highlights on some of the challenges facing the sustained advancement of research in hydrometeorology in South Africa.

    Village women have adopted techniques set down by UNICEF in achieving higher food production and, ultimately, self sufficiency. Women's cooperatives integrate kitchen gardening and irrigated agriculture in an effort to combat the complex nutritional problems in Africa. Projects also offered training in a variety of areas including management of plots, labor-saving technology--diesel-driven grinding mills, rice husking, machines, wells with hand pumps, motor pumps for irrigation, all geared towards women benefitting themselves by growing their own food and furthering their children's health and development. Projects such as the one in Senegal were undertaken in other regions of Africa, like the Sahel and the Wadis--low-lying areas. From these projects, aid agencies and governments have suggested a number of recommendations in seeking a solution to Africa's nutritional problems. 1st, a balance between production of cash crops and food for consumption is called for. 2nd, research is necessary to improve the quality of locally grown food as much as livestock. 3rd, governments should extend surface area cultivation, 4th, more research on the advantage of indigenous food plants, 5th, women should be in on all levels of decision making in food production, 6th, governments should increase women farmer's efficiency, and further women's access to land and credit and 7th, women should be provided with increased educational opportunities. Nutrition in developing countries cannot be viewed as an isolated phenomenon--solutions to nutritional development should include all aspects of the problem including health and nutrition education, growth monitoring, water supply, literacy, technological know-how, and agricultural and plant and soil conservation.

    South Africa and other areas of sub-Saharan Africa have in the past 20 years undergone rapid demographical changes, largely due to urbanisation and changes in lifestyle. This rapid change has led to a marked increase in specific cardiac conditions, such as hypertensive heart disease and coronary artery disease (with the highest prevalence in the middle-aged population), in conjunction with a range of other heart diseases, which are historically common in Africa-eg, rheumatic heart disease, cardiomyopathies, and unoperated congenital heart disease. The short supply of well-equipped screening facilities, late diagnosis, and inadequate care at primary, secondary, and tertiary levels have led to a large burden of patients with poorly treated heart failure. Excellent progress has been made in the understanding of the epidemiology, sociodemographical factors, effect of urbanisation, and pathophysiology of cardiac conditions, such as peripartum cardiomyopathy, rheumatic heart disease, and tuberculous pericarditis, which are common in sub-Saharan Africa. This progress has been achieved largely through several studies, such as the Heart of Soweto, THESUS, REMEDY, BA-HEF, Abeokuta-HF, and the PAPUCO studies. Studies on the suitable therapeutic management of several heart conditions have also been done or are underway. In this Lecture, I provide a personal perspective on the evolving burden of cardiac disease, as witnessed since my appointment at Chris Hani Baragwanath Hospital, in Soweto, South Africa, in 1992, which was also the year that the referendum to end apartheid in South Africa was held. Subsequently, a network of cardiologists was formed under the umbrella of the Heart of Africa Studies and the Pan African Cardiac Society. Furthermore, I summarise the major gaps in the health-care system dealing with the colliding epidemic of communicable and non-communicable heart diseases, including cardiac diseases common in peripartum women. I also touch on the fantastic

  9. Does China and Africa South-South cooperation lead to economic development in Africa?

    Directory of Open Access Journals (Sweden)

    Nonfodji, P.

    2013-03-01

    Full Text Available Since a few decades now Chinese enterprises’ investments abroad have seen a continuous and steady ascension. At first cautious and just across the Chinese national borders, these investments, slowly but surely, spread like a sheet of water that seeps into the heart of each continent on the globe. This global infiltration of Chinese companies coincides with the popularity in the use of the expression “South-South Cooperation” to characterize a type of relations between countries categorized as being “developing”. Accordingly this paper seeks to examine the role of the use of this concept as a “channel to achieve common development” in the context of Chinese enterprises’ outward direct investments in Africa adopting insights from international business production theories combined with an historical analysis of the notion of South-South Cooperation. Drawing on primary data gathered during my fieldwork in China in the period stretching from December 2011 to February 2012 and secondary data sources, it is argued that these Chinese investments supported by the Chinese government rhetoric on South-South cooperation, cannot lead to significant economic development in Africa like it has happened in China in the eighties. Rather and at most Chinese investments in Africa show some “trickle-down” effects characterised by very limited economic development in scattered localities throughout the African continent.

  10. Sub-Saharan Africa: Sustainability Risk Discussion

    Full Text Available Africa is a rising star - one of the most desirable investment destinations in the world. Nonetheless, economic growth is uneven among African countries, and many obstacles must be overcome in order to realize the full potential of opportunity. To achieve long-term sustainable investment results, and ultimately progress towards Sustainable Development goals, many risks must be isolated, analyzed, and mitigated. This paper introduces the concept of Sustainability Risk, identifying a set of major risk components for Sub-Saharan Africa and building an integral measure to quantify the degree of remoteness of the forty-six Sub-Saharan Africa countries from the total set of threats considered. The countries are separated into distinct groups with similar characteristics in terms of Sustainability Risk, and an analysis for potential decision-making, based on the visualization of the countries' position in relation to the major sustainability threats, is performed for each group. The research identifies risks with maximum impacts.

    To date, the earliest modern human fossils found outside of Africa are dated to around 90,000 to 120,000 years ago at the Levantine sites of Skhul and Qafzeh. A maxilla and associated dentition recently discovered at Misliya Cave, Israel, was dated to 177,000 to 194,000 years ago, suggesting that members of the Homo sapiens clade left Africa earlier than previously thought. This finding changes our view on modern human dispersal and is consistent with recent genetic studies, which have posited the possibility of an earlier dispersal of Homo sapiens around 220,000 years ago. The Misliya maxilla is associated with full-fledged Levallois technology in the Levant, suggesting that the emergence of this technology is linked to the appearance of Homo sapiens in the region, as has been documented in Africa.

  13. Marketing of irradiated commodities in South Africa

    Although the industrial exploitation of radiation processing in the medical and allied fields has been successfully marketed and applied for the past two decades in South Africa, the introduction of food radurisation on an industrial level adds a completely new dimension to the marketing of this processing technique. Extensive research into the use of radiation for the treatment of various foodstuffs has been carried out by the Nuclear Development Corporation of South Africa for more than a decade, resulting in South Africa being one of the first countries where a commercial irradiator dedicated to this branch of radiation processing, was established. The marketing of this process is especially difficult due to the emotive aspects associated with radiation and man's sensitive reaction to anything pertaining to his food. This situation was made even more difficult by the general public's apprehension towards nuclear activities throughout the world. In an attempt to transform the unfavourable public image associated with this process, an important first step was to form a National Steering Committee for the Marketing of Radurised Food, the members of which were drawn from various agricultural controlling bodies, the Department of Health, and other controlling bodies held in high esteem by the public, such as the Consumer Council and representatives from commerce and industry. This approach proved to be very successful and greatly assisted in creating a climate whereby the public in South Africa today generally has a favourable attitude towards the radurisation of foodstuffs. The development of this marketing strategy for food radurisation in South Africa is discussed in detail.
