    The epidemiology of systemic lupus erythematosus (SLE) in Africa is largely undetermined, and the perception persists that the incidence of SLE on the continent is very low. Recent studies as well as our own experience, however, suggest that this is not the case. We have conducted a survey amongst medical practitioners in Africa to determine their experiences of diagnosing and treating SLE patients, and the results suggest that significant numbers of African patients are presenting with SLE. The apparent low incidence rate in Africa may be the result of underdiagnosis due to poor access to health care, low disease recognition within primary health care settings, limited access to diagnostic tools and inadequate numbers of specialist physicians. Treatment of SLE in Africa is also restricted by availability and affordability of immunosuppressive drugs. We have established the African Lupus Genetics Network (ALUGEN), an informal network of clinicians and researchers in Africa who have an interest in SLE, in order to facilitate combined clinical and research efforts towards improved outcomes for African SLE patients.

  3. Darwin as a geologist in Africadispelling the myths and unravelling a confused knot

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Two myths persist concerning the role played by Charles Darwin as a geologist in Africa during his epic voyage around the world (1831–1836. The first myth is that Darwin was a completely self-taught geologist, with no formal training. The second myth is that it was Darwin who finally solved the problem of the granite–schist contact at the famous Sea Point coastal exposures in Cape Town, after deliberately setting out to prove his predecessors wrong. These myths are challenged by the now ample evidence that Darwin had excellent help in his geological education from the likes of Robert Jameson, John Henslow and Adam Sedgwick. The story of Darwin and his predecessors at the Sea Point granite contact has become confused, and even conflated, with previous descriptions by Basil Hall (1813 and Clark Abel (1818. Here, the historical record is unravelled and set straight, and it is shown from the evidence of his notebooks that Darwin was quite unaware of the outcrops in Cape Town. His erudite account of the contact was a result of the 8 years spent in writing and correspondence after his return to England and not because of his brilliant insights on the outcrop, as the myth would have it. While there has been little to indicate Darwin’s landfalls in Africa, a new plaque now explains the geology of the Sea Point Contact, and includes a drawing of Darwin’s ship, the Beagle, and quotes from his work.

    Menopause and methodological doubt begins by making a tongue-in-cheek comparison between Descartes' methodological doubt and the self-doubt that can arise around menopause. A hermeneutic approach is taken in which Cartesian dualism and its implications for the way women are viewed in society are examined, both through the experiences of women…

  8. Recombinant MVA vaccines: dispelling the myths.

    Science.gov (United States)

    Cottingham, Matthew G; Carroll, Miles W

    2013-09-06

    Diseases such as HIV/AIDS, tuberculosis, malaria and cancer are prime targets for prophylactic or therapeutic vaccination, but have proven partially or wholly resistant to traditional approaches to vaccine design. New vaccines based on recombinant viral vectors expressing a foreign antigen are under intense development for these and other indications. One of the most advanced and most promising vectors is the attenuated, non-replicating poxvirus MVA (modified vaccinia virus Ankara), a safer derivative of the uniquely successful smallpox vaccine. Despite the ability of recombinant MVA to induce potent humoral and cellular immune responses against transgenic antigen in humans, especially when used as the latter element of a heterologous prime-boost regimen, doubts are occasionally expressed about the ultimate feasibility of this approach. In this review, five common misconceptions over recombinant MVA are discussed, and evidence is cited to show that recombinant MVA is at least sufficiently genetically stable, manufacturable, safe, and immunogenic (even in the face of prior anti-vector immunity) to warrant reasonable hope over the feasibility of large-scale deployment, should useful levels of protection against target pathogens, or therapeutic benefit for cancer, be demonstrated in efficacy trials.

Nurses caring for women and their families in the postpartum period might wonder how to best support the breastfeeding relationship if a woman has a history of depression. Using evidence from the scientific literature, this article dispels some myths regarding breastfeeding and depression, and provides suggested dialogue nurses can use when counseling women about depression and breastfeeding.

  12. A Study of Dispelling Lexical Fossilization for English Learners

    Institute of Scientific and Technical Information of China (English)

    QI Ai-ling

    2016-01-01

    Fossilization was first proposed by the famous British linguist Larry Selinker in his article Interlanguage in 1972. Non-English majors make many lexical errors in the process of English writings in universities. Therefore, their writing levels may reach a plateau and fail to make progress. Once English vocabulary is fossilized, it will prevent the development of students’ writing competence. Inspired and stimulated by the observation of lexical errors in the university, the author intends to explore effective and feasible methods of dispelling lexical fossilization from the perspective of the theories of prototype and basic-level category and tries to provide a useful supplement in this area.

  15. DISPELLING MYTHS AND MISCONCEPTIONS TO IMPLEMENT A SAFETY CULTURE

    Energy Technology Data Exchange (ETDEWEB)

    Potts, T. Todd; Smith, Ken; Hylko, James M.

    2003-02-27

    Industrial accidents are typically reported in terms of technological malfunctions, ignoring the human element in accident causation. However, over two-thirds of all accidents are attributable to human and organizational factors (e.g., planning, written procedures, job factors, training, communication, and teamwork), thereby affecting risk perception, behavior and attitudes. This paper reviews the development of WESKEM, LLC's Environmental, Safety, and Health (ES&H) Program that addresses human and organizational factors from a top-down, bottom-up approach. This approach is derived from the Department of Energy's Integrated Safety Management System. As a result, dispelling common myths and misconceptions about safety, while empowering employees to ''STOP work'' if necessary, have contributed to reducing an unusually high number of vehicle, ergonomic and slip/trip/fall incidents successfully. Furthermore, the safety culture that has developed within WESKEM, LLC's workforce consists of three common characteristics: (1) all employees hold safety as a value; (2) each individual feels responsible for the safety of their co-workers as well as themselves; and (3) each individual is willing and able to ''go beyond the call of duty'' on behalf of the safety of others. WESKEM, LLC as a company, upholds the safety culture and continues to enhance its existing ES&H program by incorporating employee feedback and lessons learned collected from other high-stress industries, thereby protecting its most vital resource - the employees. The success of this program is evident by reduced accident and injury rates, as well as the number of safe work hours accrued while performing hands-on field activities. WESKEM, LLC (Paducah + Oak Ridge) achieved over 800,000 safe work hours through August 2002. WESKEM-Paducah has achieved over 665,000 safe work hours without a recordable injury or lost workday case since it started operations on

    2015-04-01

    Scientific workflows are a necessary tool for many scientific communities as they enable easy composition and execution of applications on computing resources while scientists can focus on their research without being distracted by the computation management. Nowadays, scientific communities (e.g. Seismology) have access to a large variety of computing resources and their computational problems are best addressed using parallel computing technology. However, successful use of these technologies requires a lot of additional machinery whose use is not straightforward for non-experts: different parallel frameworks (MPI, Storm, multiprocessing, etc.) must be used depending on the computing resources (local machines, grids, clouds, clusters) where applications are run. This implies that for achieving the best applications' performance, users usually have to change their codes depending on the features of the platform selected for running them. This work presents dispel4py, a new open-source Python library for describing abstract stream-based workflows for distributed data-intensive applications. Special care has been taken to provide dispel4py with the ability to map abstract workflows to different platforms dynamically at run-time. Currently dispel4py has four mappings: Apache Storm, MPI, multi-threading and sequential. The main goal of dispel4py is to provide an easy-to-use tool to develop and test workflows in local resources by using the sequential mode with a small dataset. Later, once a workflow is ready for long runs, it can be automatically executed on different parallel resources. dispel4py takes care of the underlying mappings by performing an efficient parallelisation. Processing Elements (PE) represent the basic computational activities of any dispel4Py workflow, which can be a seismologic algorithm, or a data transformation process. For creating a dispel4py workflow, users only have to write very few lines of code to describe their PEs and how they are

  17. Manufactured Doubt: The Campaign Against Nuclear Energy

    Science.gov (United States)

    Rogers, N. L.

    2012-12-01

    Nuclear electricity is a CO2 free technology with a proven track record of large scale commercial deployment. For example, France generates 78% of its electrical power with nuclear plants. France has the lowest pre-tax cost of electricity in Europe at 4.75 eurocents per KWH and France is the world's largest exporter of electricity. There are large world reserves of uranium sufficient for hundreds of years, even without breeder technology. Additionally, thorium, another radioactive mineral is in even more plentiful supply. Although present-day nuclear technology has proven to be safe and reliable, waiting in the wings is new generation technology that promises great improvements in both safety and cost. Yet, there has been a calculated and sophisticated campaign in the later part of the 20th century to create doubt and fear concerning nuclear power. In the United States this campaign has essentially destroyed the nuclear industry. No new plants have been commissioned for decades. Leadership in the nuclear power field has been ceded to other countries. The great paradox is that the very organizations that express great alarm concerning CO2 emissions are the same organizations that led the campaign against nuclear power decades ago. Representatives of these organizations will say privately that they are taking a new look at nuclear power, but no major organization has reversed course and become a supporter of nuclear power. To do so would involve a loss of face and create doubts concerning the credibility of the organization. As recently as 2001 environmentalist lobbyists made great efforts to ensure that no credit could be given for nuclear power under the Kyoto accords and the associated clean development mechanism. They succeeded and nuclear power receives unfavorable treatment under the Kyoto accords even though it is a proven solution for reducing CO2 emissions. The technique used to destroy nuclear energy as a viable alternative in the United States had two

  18. Incremental Beliefs About Ability Ameliorate Self-Doubt Effects

    Directory of Open Access Journals (Sweden)

    Qin Zhao

    2015-12-01

    Full Text Available Past research has typically shown negative effects of self-doubt on performance and psychological well-being. We suggest that these self-doubt effects largely may be due to an underlying assumption that ability is innate and fixed. The present research investigated the main hypothesis that incremental beliefs about ability might ameliorate negative effects of self-doubt. We examined our hypotheses using two lab tasks: verbal reasoning and anagram tasks. Participants’ self-doubt was measured and beliefs about ability were measured after participants read articles advocating either for incremental or entity theories of ability. American College Testing (ACT scores were obtained to index actual ability level. Consistent with our hypothesis, for participants who believed ability was relatively fixed, higher self-doubt was associated with increased negative affect and lower task performance and engagement. In contrast, for participants who believed that ability was malleable, negative self-doubt effects were ameliorated; self-doubt was even associated with better task performance. These effects were further moderated by participants’ academic ability. These findings suggest that mind-sets about ability moderate self-doubt effects. Self-doubt may have negative effects only when it is interpreted as signaling that ability is immutably low.

  19. Dispelling a myth: developing world poverty, inequality, violence and social fragmentation are not good for outcome in schizophrenia.

    Science.gov (United States)

    Burns, J

    2009-08-01

    The WHO multi-site studies of schizophrenia concluded the course and outcome of the disorder was better in developing countries. This has become psychiatric lore. However, the reality is that significant political, social and economic ills that characterize many countries in Africa, Latin America and Asia constitute psychosocial stressors that mediate strongly against better outcome in individuals living with this disorder. Outcome studies of schizophrenia in developing countries are reviewed and concepts of poverty, inequality and violence in relation to the course of the illness in this context are debated. The generally poor state of mental health services and policies in these regions are discussed. The belief that community and family life in the developing world is widely intact and that it provides a nurturing environment that facilitates recovery and promotes social and economic empowerment of serious mentally ill individuals is dispelled as a myth. Idealisation of the under-developed South as a haven for schizophrenia sufferers will only add to the already heavy burden experienced by these individuals, their families and these societies in coping with this disabling disease.

  1. Expression and communication of doubt/uncertainty through facial expression

    Directory of Open Access Journals (Sweden)

    Pio E. Ricci Bitti

    2014-04-01

    Full Text Available There is a wide debate on the mental state of doubt/uncertainty; one wonders whether it is a predominantly cognitive or emotional state of mind and whether typical facial expressions communicate doubt/uncertainty. To this purpose,through a role playing procedure, a large sample of expressions were collected and afterwards evaluated through a combination of encoding and decoding procedures,including also FACS (Facial Action Coding System analysis. The results have partially confirmed our hypothesis, identifying two typical facial expressions of doubt/uncertainty, which share the same facial actions in the inferior part of the face and show differential facial actions in the upper face.

  2. Without a 'doubt'? Unsupervised discovery of downward-entailing operators

    Danescu-Niculescu-Mizil, Cristian; Ducott, Richard

    2009-01-01

    An important part of textual inference is making deductions involving monotonicity, that is, determining whether a given assertion entails restrictions or relaxations of that assertion. For instance, the statement 'We know the epidemic spread quickly' does not entail 'We know the epidemic spread quickly via fleas', but 'We doubt the epidemic spread quickly' entails 'We doubt the epidemic spread quickly via fleas'. Here, we present the first algorithm for the challenging lexical-semantics problem of learning linguistic constructions that, like 'doubt', are downward entailing (DE). Our algorithm is unsupervised, resource-lean, and effective, accurately recovering many DE operators that are missing from the hand-constructed lists that textual-inference systems currently use.

  6. When in doubt follow your nose – a wayfinding strategy

    Directory of Open Access Journals (Sweden)

    Tobias eMeilinger

    2014-11-01

    Full Text Available Route selection is governed by various strategies which often allow minimizing the required memory capacity. Previous research showed that navigators primarily remember information at route decision points and at route turns, rather than at intersections which required straight walking. However, when actually navigating the route or indicating directional decisions, navigators make fewer errors when they are required to walk straight. This tradeoff between location memory and route decisions accuracy was interpreted as a when in doubt follow your nose strategy which allows navigators to only memorize turns and walk straight by default, thus considerably reducing the number of intersections to memorize. These findings were based on newly learned routes. In the present study we show that such an asymmetry in route memory also prevails for planning routes within highly familiar environments. Participants planned route sequences between locations in their city of residency by pressing arrow keys on a keyboard. They tended to ignore straight walking intersections, but they ignored turns much less so. However, for reported intersections participants were quicker at indicating straight walking than turning. Together with results described in the literature, these findings suggest that a when in doubt follow your nose strategy is applied also within highly familiar spaces and might originate from limited working memory capacity during planning a route.

  9. The certainty that engendered doubt: paternity and DNA

    Directory of Open Access Journals (Sweden)

    Claudia Fonseca

    Full Text Available There has been a surge in the use of DNA paternity tests in Brazil in both private and government laboratories. This raises interesting questions about the influence of the medical and legal spheres on gender and kinship relations in contemporary society. To analyze this phenomenon, we conducted research and observations in various government agencies in Porto Alegre (the Public Defender's office, Mediation Hearings, Family Court and the Court's Medical Service of people involved in legal disputes over paternal identification. We also studied how recent changes in the laws concerning paternal recognition are applied by the different personalities on the scene. Based on this data, we present the hypothesis that far from inspiring greater tranquility, the simple existence of the test instigates doubt. This has profound repercussions on our form of "knowing" who is the father. The situation described in this paper raises new challenges for an anthropology of knowledge, which focuses on an analysis of Western beliefs - including scientific ones.

    Hettinger, Thomas P

    2014-04-01

    The sensational "reactome array" paper published in Science in 2009 was investigated in Spain by the Ethics Committee of Consejo Superior de Investigaciones Cientificas (CSIC) after Science issued an editorial expression of concern. The paper was retracted in 2010 because of "skepticism" due to "errors" in chemistry. The "errors" were so profound that many readers expressed doubt that they were really errors, but part of an elaborate hoax. I conducted a forensic analysis of mass spectrometry data in the paper's Supporting Online Material (SOM) and was able to prove that thousands of data values were in fact fabricated. The SOM contains signatures of improper extensive spreadsheet manipulations of incorrect atomic and molecular mass values as well as impossibly repetitive deviations of found molecular mass values from their expected values. No evidence of real mass spectrometry data was detected. Both CSIC and Science have been content to retract the paper without acknowledging the fabrications or assigning responsibility for them. Neither CSIC nor Science has expressed interest in having an independent investigation determining how the paper came to be written, reviewed and published. Their weak response to this episode is a daunting signal that there is an impending crisis in research integrity and science journalism.

  12. The Status Quo and Prospect of Chinese-funded Enterprises Technology Transfer to Africa

    Yang Guang; Li Xinfeng; Chen Mo

    2015-01-01

    Weak technical foundation is an important bottleneck to restrict economic growth of African countries. To promote the technological progress of Africa, the Chinese African strategy always encourages and supports Chinese-funded enterprises to transfer technology to Africa, but it is worth nothing that the critique by some African scholars and local communities on technology transfer to Africa by the Chinese-funded enterprises is spreading. In fact, in order to implement the "localization" strategy, develop African market or honor cooperation agreement on additional technical transfer, Chinese-funded enterprises always adhere to actively carrying out technology transfer to Africa, and have made certain achievements in improving the host countries’ technical environment, increasing labor income and others. In order to cope with the challenges and dispel the crisis of public opinion, China should uphold the concept of "teaching how to fish" and push forward the continuous upgrading and optimization of technology transfer to Africa all-dimensionally.

  13. Prophecy and Doubt in Just Above My Head

    Directory of Open Access Journals (Sweden)

    Christopher Z. Hobson

    2015-09-01

    Full Text Available Written in the aftermath of the civil rights era’s expansive hopes, James Baldwin’s last novel, Just Above My Head (1979, examines a fundamental issue, the choice between hope and skepticism, or prophecy and doubt. Baldwin approaches this issue by questioning two cornerstone ideas of his fiction, the need for prophetic art and this art’s focus on anticipating a renovated society, often pictured in terms adapted from apocalyptic biblical texts and Gospel music lyrics. Just Above My Head is Baldwin’s fullest presentation of this kind of art and its linkage to apocalyptic hopes. He dramatizes these ideas in the art of his Gospel singer protagonist, particularly in a climactic scene of artistic dedication whose Gospel lyric envisions “tearing down the kingdom of this world.” Yet Baldwin also unsparingly questions these same ideas through plot and the blues-inflected skeptical-tragic consciousness of his narrator. Responding to a 1970s moment when hopes for transcendent justice seemed passé, Just Above My Head’s unique contribution is not to try to resolve the ideas it counterposes, but to face both the possible falseness of prophetic hope and our continuing need for it, and to present the necessity for choice in a final dream that holds the key to the novel’s meaning. In presenting this issue through a sustained double-voiced narrative that reexamines its author’s artistic practice and raises fundamental choices in outlook and conduct, Just Above My Head evidences the continuing artistic vitality of Baldwin’s late fiction.

    Human papillomavirus (HPV) vaccination is safe and effective in preventing anogenital cancers and warts. However, myths have surrounded the HPV vaccine since its approval, including the possibility that HPV vaccinated young people are more likely to engage in risky sexual behaviors. The purpose of this study was to assess the association between HPV vaccination and engaging in inconsistent condom use in a sample of U.S. college students. A secondary data analysis of the National College Health Assessment-II (Fall 2013) was conducted in 2015. Risky sexual activity was operationalized as inconsistent condom use for oral, vaginal or anal sexual activity. Logistic regression models were stratified by sexual activity and gender, and controlled for socio-demographics and history of STIs. Inconsistent condom use was reported among females for vaginal (47%), oral (94%), and anal sex (75%); while males reported levels of inconsistency for vaginal (38%), oral (94%), and anal sex (58%). Sixty-nine percent of females reported receiving the HPV vaccine compared to 43% of males. Among females, there was no significant association between HPV vaccination and inconsistent condom use in any of the sexual activities. Among males, there was no significant association between HPV vaccination and inconsistent condom use in oral or vaginal sex. HPV-vaccinated males were less likely to report inconsistent condom use during anal sexual activity. This study contributes to the increasing evidence that HPV vaccination is not associated with risky sexual behavior. Dispelling this myth is important to facilitate uptake and completion of the HPV vaccine in the U.S.

Exopolysaccharides (EPS contribute to the pathogenicity and antibiotic resistance of E. faecalis. Our aim was to investigate the antimicrobial activity of calcium hydroxide (CH, camphorated parachlorophenol (CMCP, and chlorhexidine (CHX against E. faecalis in dentinal tubules. Material and Methods: Decoronated single-canal human teeth and semicylindrical dentin blocks were incubated with E. faecalis for 3 weeks. Samples were randomly assigned to six medication groups for 1 week (n=10 per group: CH + 40% glycerin-water solution (1:1, wt/vol; CMCP; 2% CHX; CH + CMCP (1:1, wt/vol; CH + CMCP (2:3, wt/vol; and saline. Bacterial samples were collected and assayed for colony-forming units. After dentin blocks were split longitudinally, confocal laser scanning microscopy was used to assess the proportion of viable bacteria and EPS production in dentin. Results: CMCP exhibited the best antimicrobial activity, while CH was the least sensitive against E. faecalis (p0.05. CH combined with CMCP inhibited EPS synthesis by E. faecalis, which sensitized biofilms to antibacterial substances. Moreover, increasing concentrations of CMCP decreased EPS matrix formation, which effectively sensitized biofilms to disinfection agents. Conclusion: The EPS matrix dispelled by CH paste with CMCP may be related to its bactericidal effect; the visualization and analysis of EPS formation and microbial colonization in dentin may be a useful approach to verify medicaments for antimicrobial therapy.

  16. [Depression in Sub-Saharan Africa].

    We now have a better knowledge of the specific features of depression in sub-Saharan Africa. Anthropologically speaking, the Western model is irrelevant. Depression in sub-Saharan Africa involves the relationship of the subject to himself or others in a mode specific to African cultures. Ignoring this fact can lead to simplistic ethnocentrism. From a clinical standpoint, depressive illness characterized by somatic manifestations, delusions of persecution, and anxiety are increasingly uncommon. As African societies modernize, these traditional forms are being gradually supplanted by states with symptoms and prognoses more like those observed in industrialized countries. Hybrid depressive syndromes are now the most widespread. Epidemiologically the notion widely held only a few decades ago that depression is a rare occurrence in Africa has now been dispelled. Many studies have been conducted to determine the exact incidence, age distribution, and sex ratio but more precise data is still needed. This investigation will require improvement in screening and diagnostic methods which must be not only suitable for clinical use but also adaptable to local conditions. This is also true with regard to management which has the same goals as anywhere else in the world. Treatment facilities are different in urban and rural areas but care is often dispensed in unconventional settings and may be combined with traditional methods. Drug availability is limited by problems involving supply and cost. This explains why electro-convulsive therapy which was introduced into sub-Saharan Africa long ago still plays a major role in the treatment of depression.

    2009-03-01

    The objective of this study was to test the hypothesis that inductive reasoning plays a role in obsessional doubting by comparing an OCD sample with a non-OCD control group in performance of an inductive reasoning task. The 'Reasoning with Inductive Arguments Task' (RIAT) measures inductive performance using arguments drawn from both given vs. self-generated sources and containing neutral vs. OCD-related content. Both an OCD group recruited from clinical referrals and a control group recruited from the general population were compared on performance of the RIAT. People with OCD tended to doubt an initial conclusion much more than controls in the light of subsequent alternative conclusions given by the experimenter. There were no significant differences between the two groups in the self-generated condition. The OCD group doubted more regardless of whether the items were OCD-relevant or neutral. The control group also doubted the initial conclusions but not to the same extent as the OCD group in the 'given' condition and their degree of doubting did not differ between self-generated or given items. People with OCD may create doubt because they are giving too much credit to mental models given from external sources.

    Scientific workflows are needed by many scientific communities, such as seismology, as they enable easy composition and execution of applications, enabling scientists to focus on their research without being distracted by arranging computation and data management. However, there are challenges to be addressed. In many systems users have to adapt their codes and data movement as they change from one HPC-architecture to another. They still need to be aware of the computing architectures available for achieving the best application performance. We present dispel4py, an open-source framework presented as a Python library for encoding and automating data-intensive scientific methods as a graph of operations coupled together by data-streams. It enables scientists to develop and experiment with their own data-intensive applications using their familiar work environment. These are then automatically mapped to a variety of HPC-architectures, i.e., MPI, multiprocessing, Storm and Spark frameworks, increasing the chances to reuse their applications in different computing resources. dispel4py comes with data provenance, as shown in the screenshot, and with an information registry that can be accessed transparently from within workflows. dispel4py has been enhanced with a new run-time adaptive compression strategy to reduce the data stream volume and a diagnostic tool which monitors workflow performance and computes the most efficient parallelisation to use. dispel4py has been used by seismologists in the project VERCE for seismic ambient noise cross-correlation applications and for orchestrated HPC wave simulation and data misfit analysis workflows; two data-intensive problems that are common in today's research practice. Both have been tested in several local computing resources and later submitted to a variety of European PRACE HPC-architectures (e.g. SuperMUC & CINECA) for longer runs without change. Results show that dispel4py is an easy tool for developing, sharing and

To date, however, this literature has focused primarily on a handful of mental health outcomes (e.g., symptoms of depression, anxiety, negative affect), while the possible links with other aspects of health and well-being, such as poor or disrupted sleep, have received much less attention. After reviewing relevant theory and previous studies, we analyze data from a nationwide sample of Presbyterian Church (USA) members to test the hypothesis that religious doubts will be inversely associated with overall self-rated sleep quality, and positively associated with the frequency of sleep problems and the use of sleep medications. We also hypothesize that part of this association will be explained by the link between religious doubts and psychological distress. Results offer moderate but consistent support for these predictions. We end with a discussion of the implications of these findings, a brief mention of study limitations, and some suggestions for future research.

    Directory of Open Access Journals (Sweden)

    Laar Jan Albert van

    2014-03-01

    Full Text Available In his theory of criticism, D. N. Walton presupposes that an opponent either critically questions an argument, without supplementing this questioning with any reasoning of her own, or that she puts forward a critical question and supplements it with a counterargument, that is, with reasoning in defense of an opposite position of her own. In this paper, I show that there is a kind of in-between critical option for the opponent that needs to be taken into account in any classification of types of criticism, and that should not be overlooked in a system of dialogue norms, nor in a procedure for developing a strategically expedient critique. In this third option, an opponent questions and overtly doubts a statement of the proponent and supplements her doubts with a counterconsideration that explains and motivates her position of critical doubt, yet without supporting any opposite thesis, thereby assisting, as it were, the proponent in his attempt to develop a responsive argumentation, tailor-made to convince this particular opponent. First, I elaborate on the notion of an explanatory counterconsideration. Second, I discuss Walton’s distinction between premises that can be challenged by mere questioning (“ordinary premises” and “assumptions” and premises that must be challenged by incurring the obligation to offer counter-argumentation (somewhat confusingly labeled “exceptions”. I contend that the latter type of premises, that I would label “normality premises,” can be attacked without incurring a genuine burden of proof. Instead, it can be attacked by means of incurring a burden of criticism (Van Laar and Krabbe, 2013 that amounts to the obligation to offer an explanatory counterconsideration, rather than a convincing ex concessis argument. Of course, providing the opponent with the right to discharge her burden of criticism with explanatory counterconsiderations brings a clear strategic ad- vantage to her. It is much less

    With its vast expanses of sand, framed by mountain ranges and exposed rock, northwestern Africa makes a pretty picture when viewed from above. This image was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The Canary Islands can be seen on the left side of the image just off Africa's Atlantic shore. The light brown expanse running through the northern two thirds of the image is the Sahara Desert. The desert runs up against the dark brown Haut Atlas mountain range of Morocco in the northwest, the Atlantic Ocean to the west and the semi-arid (light brown pixels) Sahelian region in the South. The Sahara, however, isn't staying put. Since the 1960s, the desert has been expanding into the Sahelian region at a rate of up to 6 kilometers per year. In the 1980s this desert expansion, combined with over cultivation of the Sahel, caused a major famine across west Africa. Over the summer months, strong winds pick up sands from the Sahara and blow them across the Atlantic as far west as North America, causing air pollution in Miami and damaging coral reefs in the Bahamas and the Florida Keys. The white outlines on the map represent country borders. Starting at the top-most portion of the map and working clockwise, the countries shown are Morocco, Western Sahara, Mauritania, Senegal, Mali, Burkina Fasso, Nigeria, Mali (again), and Algeria.

    Nowadays, micro-lesson has become a hot spot in the development of educational informatization in our country. The emergence of micro-lesson has caused a great stir in the field of education, and aroused a wave of"micro-lesson boom". To sum up, people mainly have six doubts about micro-lesson:first, people think that micro-lesson is"short-term speculation";second, they think that micro-lesson is merely putting new wine into old bottles;third, they think that micro lesson is the"culprit"that give rise to the fragmentation of knowledge; fourth, they think that micro-lesson has little technical content; fifth, they think that micro-lesson may tend to winnow out the traditional classroom live recordings; sixth, they think that micro-lesson with varied types lacks a unified evaluation standard, a creation mode and a authoring tool. The reason why people are raising these doubts is that people lack rational thinking and practical exploration into the related problems of micro-lesson in aspects of background, realistic demand, core and essence, strengths and weaknesses, value of education, prospect of application, trend of development and creative methods, etc. In the future, the micro-lesson researchers have to work together to solve the problems in regard to principles and strategies of micro-lesson design, evaluation criteria, methods of supporting and transforming teaching and learning, ways of changing micro-lesson to micro-course, development of integrative micro-lesson platform and so on. Only solving these problems can lead the micro-lesson to a healthy and rapid development.%目前,微课已成为我国教育信息化发展的新热点。微课的出现,在教育领域掀起了轩然大波,也引发了一波波的“微课热潮”。归纳起来,人们对微课的质疑主要有六点:一是认为微课热是“短时炒作”,二是认为微课是“新瓶”装“旧酒”,三是认为微课是导致知识碎片化的“元凶”,四是认为

    Two-dimensional transthoracic echocardiography (2D-TTE) is the reference technique for evaluating aortic stenosis (AS) but may be unreliable in some cases. We aimed to assess whether the use of a pressure wire to measure simultaneous transaortic gradient and aortic valve area (AVA) could be helpful in patients in whom initial noninvasive evaluations were considered doubtful for AS. Fifty-seven patients (mean age 76 years; 39 men) underwent cardiac catheterization with single arterial access for assessment of AVA with the Gorlin and Gorlin formula. Transaortic pressure was obtained by 2 invasive methods: (1) conventional pullback method (PM) from the left ventricle toward the aorta and (2) simultaneous method (SM) with transaortic pressure simultaneously recorded with a 0.014-inch pressure wire introduced into the left ventricle and with a diagnostic catheter placed in the ascending aorta. Reasons for inaccurate assessment by 2D-TTE were low flow states (88%) and/or atrial fibrillation (79%). Agreement for severe AS defined by AVA <0.6 cm²/m² between SM and 2D-TTE and between SM and PM was fair, with kappa coefficients of 0.38 (95% confidence interval [CI] 0.14-0.75) and 0.36 (95% CI 0.22-0.7) respectively; agreement was poor between 2D-TTE and PM (kappa: 0.23; 95% CI 0.002-0.36). SM led to a reclassification of the severity of AS in 9 patients (15.8%) compared with 2D-TTE and in 11 patients (19.3%) compared with PM. In conclusion, invasive evaluation of doubtful AS by measuring simultaneous transaortic gradient using a pressure wire may provide an attractive method that can lead to a change in therapeutic strategy in a substantial proportion of patients.

    Despite consistent recommendations for antipsychotic monotherapy, antipsychotic polypharmacy (the use of two or more antipsychotic agents) and the administration of excessive doses (higher than 1000 mgr/day of chloropromazine equivalents) is a common practice in schizophrenia. The therapeutic and adverse effects of this practice are poorly studied, in particular with regards to the cognitive symptoms of the disease. In this cross-sectional study we investigated the cognitive effects of antipsychotic polypharmacy and excessive doses in 53 patients with chronic schizophrenia using non-verbal cognitive tasks involving speed of movement, memory and executive functions. No significant difference in performance scores was found between the groups under polypharmacy and monotherapy, or the groups receiving either excessive or normal doses of antipsychotics. Since these groups did not also differ in demographic, clinical, other pharmacologic parameters, in the relative anticholinergic potency of antipsychotics, or in intelligence scores, we raise doubts about the association of polypharmacy and excessive doses with non-verbal cognitive performance in chronic schizophrenia.

    Full Text Available This article addresses the issue of R&D in Italy, the institutions that finance it, its operational tools, spin-offs and start-ups, put in place to ensure that the R&D can be transformed into productive innovation, both of the process and the product. The question that is addressed concerns the funding streams for the launch and development of the operational instruments. The picture that emerges is extremely diverse and irregular between sources of income from the European Union, national Government, national research bodies and agencies, both public and private, the Italian regions and local entities (EELL directly and through their subsidiary companies. It leads to the question that this article attempts to answer: is the assertion that insufficient resources are devoted to R&D true? With regard to this, there are numerous legitimate doubts, and there is reason to believe that the fact there are so many channels for dispersing the resources devoted to R&D is primarily related to the excessive number of sources of funding, not to mention the evaluative procedures and timing for allocating funds. This is one aspect. The main issue is the lack of a widely shared programming policy, based on the priorities of the national and local communities for responses to their human needs.

    This research explored the feasibility of using multidimensional scaling (MDS) analysis in novel combination with other techniques to study comprehension of epistemic adverbs expressing doubt and certainty (e.g., evidently, obviously, probably) as they relate to health communication in clinical settings. In Study 1, Australian English speakers performed a dissimilarity-rating task with sentence pairs containing the target stimuli, presented as "doctors' opinions." Ratings were analyzed using a combination of cultural consensus analysis (factor analysis across participants), weighted-data classical-MDS, and cluster analysis. Analyses revealed strong within-community consistency for a 3-dimensional semantic space solution that took into account individual differences, strong statistical acceptability of the MDS results in terms of stress and explained variance, and semantic configurations that were interpretable in terms of linguistic analyses of the target adverbs. The results confirmed the feasibility of using MDS in this context. Study 2 replicated the results with Canadian English speakers on the same task. Semantic analyses and stress decomposition analysis were performed on the Australian and Canadian data sets, revealing similarities and differences between the two groups. Overall, the results support using MDS to study comprehension of words critical for health communication, including in future studies, for example, second language speaking patients and/or practitioners. More broadly, the results indicate that the techniques described should be promising for comprehension studies in many communicative domains, in both clinical settings and beyond, and including those targeting other aspects of language and focusing on comparisons across different speech communities.

    Menstrual education is a vital aspect of adolescent health education. Culture, awareness, and socioeconomic status often exert profound influence on menstrual practices. However, health education programs for young women in developing countries do not often address menstrual hygiene, practices, and disorders. Developing culturally sensitive menstrual health education and hygiene programs for adolescent females has been recommended by professional health organizations like the World Health Organization and UNICEF. These programs cannot be developed without understanding existing myths and perceptions about menstruation in adolescent females of developing countries. Thus, the purpose of this qualitative study from India was to document existing misconceptions regarding menstruation and perceptions about menarche and various menstrual restrictions that have been understudied. Out of the 612 students invited to participate by asking questions, 381 girls participated by asking specific questions about menstruation (response rate = 62%). The respondents consisted of 84 girls from sixth grade, 117 from seventh grade, and 180 from eighth grade. The questions asked were arranged into the following subthemes: anatomy and physiology, menstrual symptoms, menstrual myths and taboos, health and beauty, menstrual abnormalities, seeking medical advice and home remedies; sanitary pads usage and disposal; diet and lifestyle; and sex education. Results of our study indicate that students had substantial doubts about menstruation and were influenced by societal myths and taboos in relation to menstrual practices. Parents, adolescent care providers, and policy makers in developing countries should advocate for comprehensive sexuality education and resources (e.g., low-cost sanitary pads and school facilities) to promote menstrual health and hygiene promotion.

  6. Odd complaints and doubtful conditions: norms of hypochondria in Jane Austen and Catherine Belling.

    Nelson, James Lindemann

    2014-06-01

    In her final fragmentary novel Sanditon, Jane Austen develops a theme that pervades her work from her juvenilia onward: illness, and in particular, illness imagined, invented, or self-inflicted. While the "invention of odd complaints" is characteristically a token of folly or weakness throughout her writing, in this last work imagined illness is also both a symbol and a cause of how selves and societies degenerate. In the shifting world of Sanditon, hypochondria is the lubricant for a society bent on turning health into a commodity. As a result, people's rationality and their moral character come under attack. Catherine Belling's recent subtle study, A Condition of Doubt: The Meanings of Hypochondria, unveils hypochondria's discursive and cultural character. Running sharply against the tenor of Austen's treatment, however, she argues in defense of the rationality of hypochondriacs; the notion that the condition may involve morally significant defects is not entertained; any connection to the commercialization of health care is muted. Here, I contrast Austen's morally and epistemically negative rendering of her hypochondriacal characters in Sanditon with Belling's efforts to create a sympathetic understanding of people with hypochondria. I will argue that, despite time gaps and genre differences, joint consideration of these texts can help bioethicists better appreciate how medicine can intensify, pathologize, and exploit anxieties about illness and death, thus adding to the challenges of living well in the face of mortality and morbidity.

  7. Some Doubts on the Validity of the Foreground Galactic Contribution Subtraction from Microwave Anisotropies

    The Galactic foreground contamination in CMBR anisotropies, especially from the dust component, is not easily separable from the cosmological or extragalactic component. In this paper, some doubts will be raised concerning the validity of the methods used until now to remove Galactic dust emission and will show that none of them achieves its goal. First, I review the recent bibliography on the topic and discuss critically the methods of foreground subtraction: the cross-correlation with templates, analysis assuming the spectral shape of the Galactic components, the ``maximum entropy method”, ``internal linear combination”, and ``wavelet-based high resolution fitting of internal templates”. Second, I analyse the Galactic latitude dependence from WMAP data. The frequency dependence is discussed with data in the available literature. The result is that all methods of subtracting the Galactic contamination are inaccurate. The Galactic latitude dependence analysis or the frequency dependence of the anisotropies in the range 50–250 GHz put a constraint on the maximum Galactic contribution in the power spectrum to be less than ∼ 10% (68% C. L.) for an ∼ 1 degree scale, and possibly higher for larger scales. The origin of most of the signals in the CMBR anisotropies is not Galactic. In any case, the subtraction of the galaxy is not accurate enough to allow a ``precision Cosmology”; other sources of contamination (extragalactic, solar system) are also present.

    Full Text Available Aim: To determine and analyse an alternative methodology for the analysis of a set of Likert responses measured on a common attitudinal scale when the primary focus of interest is on the relative importance of items in the set - with primary application to health-related quality of life (HRQOL measures. HRQOL questionnaires usually generate data that manifest evident departures from fundamental assumptions of Analysis of Variance (ANOVA approach, not only because of their discrete, bounded and skewed distributions, but also due to significant correlation between mean scores and their variances. Material and Methods: Questionnaire survey with SF-36 has been conducted among 142 convalescents after acute pancreatitis. The estimated scores of HRQOL were compared with use of the multiple comparisons procedures under Bonferroni-like adjustment, and with the bootstrap procedures. Results: In the data set studied, with the SF-36 outcome, the use of the multiple comparisons and bootstrap procedures for analysing HRQOL data provides results quite similar to conventional ANOVA and Rasch methods, suggested at frames of Classical Test Theory and Item Response Theory. Conclusions: These results suggest that the multiple comparisons and bootstrap both are valid methods for analysing HRQOL outcome data, in particular at case of doubts with appropriateness of the standard methods. Moreover, from practical point of view, the processes of the multiple comparisons and bootstrap procedures seems to be much easy to interpret by non-statisticians aimed to practise evidence based health care.

    Full Text Available The freshwater prawns of the genus Macrobrachium Spence Bate, 1868 are widely distributed in rivers of tropical and subtropical regions and represent an interesting group with controversial taxonomy. The morphological characters traditionally used to separate species have shown a high intraspecific variation. Doubts about the status of M. birai Lobão, Melo & Fernandes, 1986, M. holthuisi Genofre & Lobão, 1978 and M. petronioi Melo, Lobão & Fernandes, 1986 have been arisen due to the high resemblance of the former two species with M. olfersi (Wiegmann, 1836, and the latter one with M. potiuna (Müller, 1880. Therefore, we performed a detailed morphological analysis of these species, including new characters not usually used in the species recognition. The present results here with molecular data lead us to conclude that M. birai and M. holthuisi are junior synonyms of M. olfersi, and M. petronioi is a junior synonym of M. potiuna. Considering these synonymies, 17 valid species are now reported for the Brazilian territory.

    Full Text Available We have proposed the False Tagging Theory as a neurobiological model of belief and doubt processes. The theory posits that the prefrontal cortex is critical for normative doubt toward properly comprehended ideas or cognitions. Such doubt is important for advantageous decisions, for example in the financial and consumer purchasing realms. Here, using a neuropsychological approach, we put the False Tagging Theory to an empirical test, hypothesizing that focal damage to the ventromedial prefrontal cortex would cause a doubt deficit that would result in higher credulity and purchase intention for consumer products featured in misleading advertisements. We presented 8 consumer ads to 18 patients with focal brain damage to the ventromedial prefrontal cortex, 21 patients with focal brain damage outside the prefrontal cortex, and 10 demographically similar healthy comparison participants. Patients with ventromedial prefrontal cortex damage were (1 more credulous to misleading ads; and (2 showed the highest intention to purchase the products in the misleading advertisements, relative to patients with brain damage outside the prefrontal cortex and healthy comparison participants. The pattern of findings was obtained even for ads in which the misleading bent was corrected by a disclaimer. The evidence is consistent with our proposal that damage to the ventromedial prefrontal cortex disrupts a false tagging mechanism which normally produces doubt and skepticism for cognitive representations. We suggest that the disruption increases credulity for misleading information, even when the misleading information is corrected for by a disclaimer. This mechanism could help explain poor financial decision-making when persons with ventromedial prefrontal dysfunction (e.g., caused by neurological injury or aging are exposed to persuasive information.

Such doubt is important for advantageous decisions, for example in the financial and consumer purchasing realms.

  15. Doubt, defiance, and identity: Understanding resistance to male circumcision for HIV prevention in Malawi.

    Parkhurst, Justin O; Chilongozi, David; Hutchinson, Eleanor

    2015-06-01

    Global policy recommendations to scale up of male circumcision (MC) for HIV prevention tend to frame the procedure as a simple and efficacious public health intervention. However, there has been variable uptake of MC in countries with significant HIV epidemics. Kenya, for example, has embraced MC and has been dubbed a 'leader' by the global health community, while Malawi has been branded a 'laggard' in its slow adoption of a national programme, with a strong political discourse of resistance forming around MC. Regardless of any epidemiological or technical evidence, the uptake of international recommendations will be shaped by how a policy, and the specific artefacts that constitute that policy, intersect with local concerns. MC holds particular significance within many ethnic and religious groups, serving as an important rite of passage, but also designating otherness or enabling the identification of the social and political self. Understanding how the artefact of MC intersects with local social, economic, and political contexts, is therefore essential to understand the acceptance or resistance of global policy recommendations. In this paper we present an in-depth analysis of Malawi's political resistance to MC, finding that ethnic and religious divisions dominating recent political movements aligned well with differing circumcision practices. Political resistance was further found to manifest through two key narratives: a 'narrative of defiance' around the need to resist donor manipulation, and a 'narrative of doubt' which seized on a piece of epidemiological evidence to refute global claims of efficacy. Further, we found that discussions over MC served as an additional arena through which ethnic identities and claims to power could themselves be negotiated, and therefore used to support claims of political legitimacy.

  16. Comprehending Adverbs Of Doubt And Certainty In Health Communication: A Multidimensional Scaling Approach

    Directory of Open Access Journals (Sweden)

    Norman S. Segalowitz

    2016-05-01

    Full Text Available This research explored the feasibility of using multidimensional scaling (MDS analysis in novel combination with other techniques to study comprehension of epistemic adverbs expressing doubt and certainty (e.g., evidently, obviously, probably as they relate to health communication in clinical settings. In Study 1, Australian English speakers performed a dissimilarity-rating task with sentence pairs containing the target stimuli, presented as doctors' opinions. Ratings were analyzed using a combination of cultural consensus analysis (factor analysis across participants, weighted-data classical-MDS, and cluster analysis. Analyses revealed strong within-community consistency for a 3-dimensional semantic space solution that took into account individual differences, strong statistical acceptability of the MDS results in terms of stress and explained variance, and semantic configurations that were interpretable in terms of linguistic analyses of the target adverbs. The results confirmed the feasibility of using MDS in this context. Study 2 replicated the results with Canadian English speakers on the same task. Semantic analyses and stress decomposition analysis were performed on the Australian and Canadian data sets, revealing similarities and differences between the two groups. Overall, the results support using MDS to study comprehension of words critical for health communication, including in future studies, for example, second language speaking patients and/or practitioners. More broadly, the results indicate that the techniques described should be promising for comprehension studies in many communicative domains, in both clinical settings and beyond, and including those targeting other aspects of language and focusing on comparisons across different speech communities.

    To take post-phenomenology as some kind of Husserl's transcendental phenomenology is a misreading in-stead of a right way to understand D Ihde's philosophy of technology.Since the divergence on some fundamental con-cepts such as epoch and variation,post-phenomenology can only be taken as some kind of revised phenomenology. Actually,the deviation of post-phenomenology from its classic version is a result of learning from J.Dewey's Prag-matisim especially in ontology and epistemology.P.Ricoure's phenomenological Hermeneutics and his idea on a gen-eralized notion on text set a sketch for post-phenomenology as a philosophy of technology to inquiry the meaning of artifacts.These two dimensions,the pragmatic and the hermeneutic,of D.Idhe's philosophy of technology are two important but neglected elements in the explanation of Ihdeology.%用胡塞尔先验现象学的立场来理解作为技术哲学的后现象学,这是对唐·伊德思想的一种误解。由于在悬置和变更等基本概念上与胡塞尔现象学出入甚大,后现象学只能算是一种修正主义的现象学;在哲学观和技术观上,后现象学更多地是汲取了杜威实用主义的观点;利科的解释学及对文本概念的广义理解,决定了后现象学必然是一种以探究人工物的意义为旨归的物的解释学。在理解伊德技术哲学时,实用主义和解释学是两个重要、但被忽略的维度。

    This study aims to investigate the additive or synergistic effects and mechanism of intestinal absorption of extracts from two commonly used 'dispelling-wind' TCM botanical drugs [roots of Angelica dahurica (Hoffm.) Benth. & Hook. f. ex Franch. & Sav. (RAD) and Saposhnikovia divaricata (Turcz.) Schischk. (RSD)] using chlorogenic acid as a marker substance. Ex vivo everted intestinal sac and in situ single pass perfusion methods using rats were employed to investigate the effects of two TCM botanical drugs extracts on the intestinal absorption of chlorogenic acid. Both the extracts of RAD and RSD showed synergistic properties on the intestinal absorption of chlorogenic acid. The verapamil (a P-gp inhibitor) and intestinal dysbacteriosis model induced by norfloxacin increased the P(app) and K(a) of intestinal absorption of chlorogenic acid. These synergistic effects on intestinal absorption in a rat model can be correlated with the inhibition of P-gp and regulation of gut microbiota. This experimental approach has helped to better understand changes in the absorption of chlorogenic acid under different conditions.

    Full Text Available Abstract Background Virus Resistant Cassava for Africa (VIRCA is an agricultural biotechnology public-private partnership (PPP comprising the Donald Danforth Plant Sciences Center (DDPSC, National Agricultural Research Organization (NARO of Uganda and Kenya Agricultural Research Institute (KARI. The project seeks to develop virus-resistant cassava for farmers in Kenya and Uganda. Yet, there is much public skepticism about the use of genetically modified (GM crops and private sector involvement in Africa. This case study sought to understand the role of trust in the VIRCA partnership. Methods We conducted semi-structured, face-to-face interviews to obtain stakeholders’ views on the challenges to, and practices for, building trust in the VIRCA partnership. Interviewee responses, together with relevant documents and articles, were analyzed to generate descriptions of how trust is operationalized in this evolving agbiotech PPP. Data were analyzed based on recurring and emergent themes from the interviewee responses. Results Various factors undermine and build trust in agbiotech PPPs. Individual and institutional enthusiasm and detailed collaborative agreements stipulating partner roles and responsibilities are likely to enhance trust among partners. On the other hand, negative perceptions propagated by international partners about the capacities of African institutions and scientists, coupled with slow regulatory processes in Africa, are likely to be impediments to trust building. Conclusions Based on the findings of this study, we have derived four key lessons. First, differences in the capacity of the partner institutions and individuals should be respected. Second, technical and infrastructural capacity support for regulatory processes in Africa must be built. Third, detailed agreements and open and transparent partner practices during project implementation are necessary to dispel perceptions of inequality among partners. Fourth, institutional

    Full Text Available Though his fiction is deeply linked to Rome and Italy, we cannot understand the cultural figure of Alberto Moravia (1907-1990, if we do not consider his experience as a traveller. In particular, there is no other Italian or European writer of his generation, who had such a tight connection with Africa, which Moravia used to visit almost every year from 1963 until 1987. He wrote three books on this continent. «I would have to go to Africa twenty, thirty years before: instead I went very late in my life, when I was fifty. I do not know why I didn’t. I regret it. For me, Africa is the most beautiful thing in the world». This paper reconstructs the reasons and the stages that brought Moravia to Africa in detail, it also focuses on his travels as a European citizen, who  starts his journey from the coasts to the “heart of the black continent", sometimes following  the footsteps of his favorite Africanist writers, such as Conrad, Rimbaud, Gide, Hemingway and Céline, but always pursuing his own question, looking for his own Africa, which is indeed connected to his deepest self. The movement to Africa has changed the Roman writer, as his last novels clearly show, that whereby include Africa becomes one of their major themes.

    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.

    Full Text Available In Africa, economic integration, realised through regional integration, is seen as one of the driving factors that will improve the lives of its people. To enable regionalisation, economic growth and to unlock the potential of Africa its infrastructure will have to be improved. Infrastructure will on the whole be realised through public procurement. The stages for opening up procurement markets, referred to by Yukins and Schooner, is discussed and it is concluded that the states in SADC is still in the initial stages of opening its public procurement markets for regional competition. Although COMESA is not yet in full compliance with all four the stages great strides have been made and have elements of all stages been addressed. Because of the influence the Model Law has already played in COMESA, and the rest of Africa, it would be contra productive should SADC not take the same route as COMESA. If regard is had to the four categories of procurement rules that serves as barriers to national procurement markets, as set out by Arrowsmith it is clear that all of these are present in most SADC member states. Also in the case of COMESA these barriers still exist albeit to a lesser extent. What is necessary is a phased approach to address all of these barriers. This will be possible under the UNCITRAL Model Law as the 2011 Model Law does provide for the possibility of complying with international obligations and for states to allow for socio economic objectives in their procurement regimes. There can be little doubt that the 1994 Model Law has already had a marked influence on public procurement regulation in Africa and that the 2011 Model Law will in future continue to do so. Public procurement is essential for economic development and is the integration and harmonisation thereof on a regional basis the first step In this regard SADC, and especially South Africa, has an important role to play.

    While the future suspension of the oil embargo against South Africa will no doubt help revitalize the region's most powerful economy, a move away from dependence on coal as the major local energy source is also likely. This could be accomplished through regional cooperation and development were it not for the ongoing conflict in Angola, the only producer of oil and gas in the Southern African Development Community. Even with world oil prices in the doldrums, massive foreign exchange savings would result from a domestic source, and in line with world trends the possibility of harnessing the gas resources of the region is increasingly seen as a possibility. For the present, those resources remain to be defined. But ENH of Mozambique is pursuing an appraisal program for Pande field with World Bank funding, while Shell and its partners are considering possibilities of Kudu field in Namiba. And while South Africa's own national oil company, Soekor, has had limited success with its search for oil during the apartheid years, offshore F-A gas field is in production, and the potential for hydrocarbons-gas in particular--requires a great deal more investigation. The colleagues have prepared a series of articles on basins off South Africa. These articles were prepared in anticipation of the completion of political reform and of the start of a licensing round, possibly during 1994. This article draws together summaries of aspects thought to be most pertinent to petroleum exploration.

    Children with hearing loss who happen to reside in Africa deserve the chance to develop according to their potential as much as their peers living in more affluent regions. This leaves a moral obligation to pursue ways of initiating, developing,and growing early hearing detection and intervention services in Africa. For these reasons, the first EHDI Africa international conference was held in Johannesburg, South Africa, in 2007 (13-14 August). The theme was 'Building bridges in Africa: Early childhood development for children with hearing loss'. This special issue contains several reports from the EHDI Africa conference.

    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.

    The government of South Africa has identified astronomy as a field in which their country has a strategic advantage and is consequently investing very significantly in astronomical infrastructure. South Africa now operates a 10-m class optical telescope, the Southern African Large Telescope (SALT), and is one of two countries short listed to host the Square Kilometre Array (SKA), an ambitious international project to construct a radio telescope with a sensitivity one hundred times that of any existing telescope. The challenge now is to produce an indigenous community of users for these facilities, particularly from among the black population which was severely disadvantaged under the apartheid regime. In this paper I briefly describe the observing facilities in Southern Africa before going on to discuss the various collaborations that are allowing us to use astronomy as a tool for development, and at the same time to train a new generation of astronomers who will be well grounded in the science and linked to ...

    Full Text Available Life is all about movements and activities. Our entire livelihood and existence comes into trouble, we become immobile and inactive due to joint pains and swelling. Gout is one such condition, which affects an individual’s life. Gout is a type of arthritis that occurs, when too much uric acid builds up in the body, causing deposition of urate crystals in the joints. It is accompanied by excruciating, unexpected, burning pain, swelling and inflammation leading to complete immobility of the joints. Gout can be hereditary. Excessive intake of certain types of food, alcohol, infection, physical or emotional stress, or the use of certain drugs can lead to the development of gout symptoms. Gout occurs commonly in men (over 40 years of age affecting their toes, but can appear in other parts of the body as well. It affects women too, especially after menopause. Low-grade fever may be present during gout attack. The crystals formed inside the joints cause intense and debilitating pain. The inflammation of the tissues around the joint causes the skin to become swollen, tender and sore, to even a slight touch. The lightest sheet draping over the affected area could cause extreme pain. It is commonly treated with anti- inflammatory medicines or corticosteroid drugs. The patients always seek for fast and quick relief, so that they can resume their daily routine. The present review article focuses on the causes, pathophysiology and various treatment options available to the gout patient.

    2002-04-01

    Sub-Saharan Africa is the epicenter of the HIV/AIDS epidemic, and in this issue of the Journal, seven authors discuss the moral, social and medical implications of having 70% of those stricken living in this area. Anton A. van Niekerk considers complexities of plague in this region (poverty, denial, poor leadership, illiteracy, women's vulnerability, and disenchantment of intimacy) and the importance of finding responses that empower its people. Solomon Benatar reinforces these issues, but also discusses the role of global politics in sub-Saharan Africa, especially discrimination, imperialism and its exploitation by first world countries. Given the public health crisis, Udo Schüklenk and Richard E. Ashcroft defend compulsory licensing of essential HIV/AIDS medications on consequentialist grounds. Keymanthri Moodley discusses the importance of conducting research and the need to understand a moderate form of communitarianism, also referred to as "ubuntu" or "communalism", to help some Africans understand research as an altruistic endeavour. Godfrey B. Tangwa also defends traditional African values of empathy and ubuntu, discussing how they should be enlisted to fight this pandemic. Loretta M. Kopelman criticizes the tendency among those outside Africa to dismiss the HIV/AIDS pandemic, attributing one source to the ubiquitous and misguided punishment theory of disease. The authors conclude that good solutions must be cooperative ventures among countries within and outside of sub-Saharan Africa with far more support from wealthy countries.

    1998-01-01

    This article reviews scientific and other literature during the 1990s that links migration and mobility with the spread of sexually transmitted diseases (STDs), including HIV/AIDS. The focus is on key population groups linked to the spread of HIV and STDs in West and Central Africa: migrant laborers, truck drivers, itinerant traders, commercial sex workers (CSWs), and refugees. Countries with high emigration and immigration tend to have high levels of HIV infection, with the exception of Senegal. The main destination of immigrants are Senegal, Nigeria, and Cote d'Ivoire in West Africa and Cameroon, Congo, Gabon, and Congo in Central Africa. The risk of infection and the spread of HIV is variable among migrants. There is little in the literature that substantiates hypotheses about the strong association between migration and HIV-positive status. Information is needed on the duration, frequency of return visits, living conditions, sexual activities with multiple partners, and information before departure, along the routes, at final destination, and at the time of returns. Action-based research in five West African countries (Burkina Faso, Cote d'Ivoire, Mali, Niger, and Senegal) should produce results in late 1998. Comparable studies in Central Africa are unknown. Regional studies should be complemented by local studies. Prevention would benefit from studies on the relative size of these five population groups by geographic location.

    2014-01-01

    During the current seventh cholera pandemic, Africa bore the major brunt of global disease burden. More than 40 years after its resurgence in Africa in 1970, cholera remains a grave public health problem, characterized by large disease burden, frequent outbreaks, persistent endemicity, and high CFRs, particularly in the region of the central African Great Lakes which might act as reservoirs for cholera. There, cases occur year round with a rise in incidence during the rainy season. Elsewhere in sub-Saharan Africa, cholera occurs mostly in outbreaks of varying size with a constant threat of widespread epidemics. Between 1970 and 2011, African countries reported 3,221,050 suspected cholera cases to the World Health Organization, representing 46 % of all cases reported globally. Excluding the Haitian epidemic, sub-Saharan Africa accounted for 86 % of reported cases and 99 % of deaths worldwide in 2011. The number of cholera cases is possibly much higher than what is reported to the WHO due to the variation in modalities, completeness, and case definition of national cholera data. One source on country specific incidence rates for Africa, adjusting for underreporting, estimates 1,341,080 cases and 160,930 deaths (52.6 % of 2,548,227 estimated cases and 79.6 % of 209,216 estimated deaths worldwide). Another estimates 1,411,453 cases and 53,632 deaths per year, respectively (50 % of 2,836,669 estimated cases and 58.6 % of 91,490 estimated deaths worldwide). Within Africa, half of all cases between 1970 and 2011 were notified from only seven countries: Angola, Democratic Republic of the Congo, Mozambique, Nigeria, Somalia, Tanzania, and South Africa. In contrast to a global trend of decreasing case fatality ratios (CFRs), CFRs have remained stable in Africa at approximately 2 %. Early propagation of cholera outbreaks depends largely on the extent of individual bacterial shedding, host and organism characteristics, the likelihood of people coming into contact with

On the other hand, Science opens fields, stimulates curiosity and allows questioning even without one recognizing it. The difference between the ways of thinking reality and knowledge does not need to be fought at the costs of weakening both.

    There is no doubt that the effects of war extend to the most vulnerable members of society, including children. Although armed conflicts occur throughout the world, the African continent seems to be a particular background for civil and international wars. The aim of this study was to identify causes of conflict in Africa and to evaluate the effect of war on children and their health in order to make practical recommendations to health care workers dealing with children in the setting of war. All articles written in the past 5 years concerning "war" and "children" were identified by means of a literature search and internet review. Contrary to common belief, the causes of conflict are complicated and multi-factorial. The effects of war on childhood are disastrous and include severe negative effects on general paediatric health status. Short-term recommendations for health care workers working with children in war include supply of emergency medical infrastructures, basic health care, rehabilitation and education. Long-term recommendations include orchestrating the relief and support efforts from both national governments and international non-profit organisations and speeding up of economic recovery. The causes of conflict in Africa are complex and unlikely to be resolved soon. The effects of war on children are horrendous in many ways, but can be limited by providing timely and appropriate health care.

    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

    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.

    2007-01-01

    Drought settled over West Africa's Ivory Coast region when wet season rains came late in 2007. Instead of beginning in February, the rainy season didn't start until March, and steady rains didn't start until late March, said the Famine Early Warning System Network. Though the rain had started to alleviate the drought, vegetation was still depressed in parts of Cote d'Ivoire (Ivory Coast) between March 22 and April 6, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured the data used to make this image. The image shows current vegetation conditions compared to average conditions recorded since 2000. Areas where plants are growing more slowly or more sparsely than average are brown, while areas where vegetation is denser than average are green. The brown tint that dominates the image indicates that plants through most of the country are more sparse than normal. Among the crops affected by the lack of rain was West Africa's cocoa crop. About 70 percent of the world's cocoa comes from West Africa, and Cote d'Ivoire is a top grower, said Reuters. Cocoa prices climbed as the crop fell short. Farmers called the drought the worst in living memory, Reuters said. The delay in rainfall also led to water shortages in parts of Cote d'Ivoire, according to the United Nations Office for the Coordination of Humanitarian Affairs.

  14. Astrophysics in Southern Africa

    The government of South Africa has identified astronomy as a field in which their country has a strategic advantage and is consequently investing very significantly in astronomical infrastructure. South Africa now operates a 10-m class optical telescope, the Southern African Large Telescope (SALT), and is one of two countries short listed to host the Square Kilometre Array (SKA), an ambitious international project to construct a radio telescope with a sensitivity one hundred times that of any existing telescope. The challenge now is to produce an indigenous community of users for these facilities, particularly from among the black population which was severely disadvantaged under the apartheid regime. In this paper I briefly describe the observing facilities in Southern Africa before going on to discuss the various collaborations that are allowing us to use astronomy as a tool for development, and at the same time to train a new generation of astronomers who will be well grounded in the science and linked to their colleagues internationally.

    Full Text Available The new constitutional dispensation, like the idea of freedom in South Africa, is also not free of scepticism. Many a time when crime and criminal activity are rife, sceptics would lament the absence of ubuntu in society and attribute this absence to what they view as the permissiveness which is said to have been brought about by the Constitution with its entrenched Bill of Rights.Firstly, I would like to take this opportunity and (attempt to demonstrate the irony that the absence of the values of ubuntu in society that people often lament about and attribute to the existence of the Constitution with its demands for respect for human rights when crime becomes rife, are the very same values that the Constitution in general and the Bill of Rights in particular aim to inculcate in our society.Secondly, against the background of the call for an African renaissance that has now become topical globally, I would like to demonstrate the potential that traditional African values of ubuntu have for influencing the development of a new South African law and jurisprudence.The concept ubuntu, like many African concepts, is not easily definable. In an attempt to define it, the concept has generally been described as a world-view of African societies and a determining factor in the formation of perceptions which influence social conduct. It has also been described as a philosophy of life.Much as South Africa is a multicultural society, indigenous law has not featured in the mainstream of South African jurisprudence. Without a doubt, some aspects or values of ubuntu are universally inherent to South Africa’s multi cultures.The values of ubuntu are therefore an integral part of that value system which had been established by the Interim Constitution.The founding values of the democracy established by this new Constitution arguably coincide with some key values of ubuntu(ism.Ubuntu(-ism, which is central to age-old African custom and tradition however, abounds

    1993-01-01

    The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

    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.

    Africa is a continent with a large burden of both infectious and non-communicable diseases. If we are to move forward as a continent, we need to equip our growing cadre of exceptional young scientists with the skills needed to tackle the diseases endemic to this continent. For this, immunology is among the key disciplines. Africans should be empowered to study and understand the diseases that affect them, and to perform their cutting-edge research in their country of origin. This requires a multifaceted approach, with buy-in from funders, overseas partners and perhaps, most important of all, African governments themselves.

    Since the 1st oil crisis in 1973, the economies of sub-Saharan Africa have barely kept pace with their burgeoning populations. Women in Sub-Saharan Africa give birth more often than women in any other region of the world, with an average of more than 6.5 live births each. The region's natural increase average 2.5% a year in the 1960s, 2.7% in the 1970s, and in the mid-1980s, it is 3.1% per annum--a rate that will double the regions population in 22 years. National leaders in Sub-Saharan Africa were slow to consider population policy as a key component of the social and economic development effort. The neglect of population issues is reflected in the limited scope of public or private family planning programs in the sub-continent. Donor countries and institutions play an important role in developing the information base by providing technical training to government staff, supporting research, and disseminating information to a broad spectrum of political actors. Some examples of policy reconsiderations in Nigeria, Zambia, Liberia, and Niger are given. These countries are starting to give active consideration to population policies to reduce fertility and high rates of population growth by expanding family planning services, raising the age of marriage, improving the status of women, providing family-life education, and incorporating economic incentives for smaller families into the provision of social services. The highly centralized nature of African governments dictates that the acquiescence of the governmental elite must be obtained before any policy can take hold. Overall, high population growth rates in combination with a stagnating social and economic development effort throughout the region have provided the catalyst for a new look at Sub-Saharan Africa population policy. The ability of African nations to implement policies that reduce fertility is more open to question; no African nation has as yet done so, and the socioeconomics factors contributing to high

    1989-03-01

    Numerous cultural practices and attitudes in Africa represent formidable obstacles to the prevention of the further spread of acquired immunodeficiency syndrome (AIDS). Polygamy and concubinage are still widely practiced throughout Africa. In fact, sexual promiscuity on the part of males is traditionally viewed as positive--a reflection of male supremacy and male sexual prowess. The disintegration of the rural African family, brought about by urbanization, the migrant labor system, and poverty, has resulted in widespread premarital promiscuity. Contraceptive practices are perceived by many as a white conspiracy aimed at limiting the growth of the black population and thereby diminishing its political power. Condom use is particularly in disfavor. Thus, AIDS prevention campaigns urging Africans to restrict the number of sexual partners and to use condoms are unlikely to be successful. Another problem is that most Africans cannot believe that AIDS is sexually linked in that the disease does not affect the sex organs as is the case with other sexually transmitted diseases. The degree to which African governments are able to allocate resources to AIDS education will determine whether the epidemic can be controlled. Even with a massive outpouring of resources, it may be difficult to arouse public alarm about AIDS since Africans are so acclimated to living with calamities of every kind.

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.

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.

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

  6. South Africa in the BRICS

    Directory of Open Access Journals (Sweden)

    Philip Harrison

    2014-06-01

    Full Text Available South Africa’s membership of the BRICS has stirred controversy. A number of observers have argued that South Africa is too small in terms of economy and population to be considered an authentic member of this group. In this article, the author accepts that South Africa may have no place in the analytical construct that Jim O’Neill of Goldman Sachs invented in 2001, but also argues that South Africa is a valuable and legitimate member of the political construct that we know today as the BRIC(S. South Africa has the “soft power” needed to play a constructive role in the rebalancing of geopolitical power globally, and is a potential voice for the continent of Africa. However, South Africa’s position in the BRICS must be understood in terms of its own contested role as a leader in Africa; the ambiguous outcomes of the BRICS engagement with this continent; and the danger that the BRICS may become an exclusive self-selected grouping rather than a potent force for greater global equity.

  7. Globalisation and local power: influences on health matters in South Africa.

    Science.gov (United States)

    Gilbert, Tal; Gilbert, Leah

    2004-03-01

    This paper reviews some of the multiple influences on health issues in South Africa, placing them in the context of globalisation. By examining the complexity of factors, both domestic and global, which impact on these issues, it questions the extent to which global patterns in areas such as health policy, HIV/AIDS, health care pluralism, and neo-liberal macroeconomic policy have played out in South Africa. The identification of some of the multiple and complex forces in each case reveals a relatively consistent story of global pressures interacting with domestic realities, with some recognizably local results. There is no doubt that a full and nuanced understanding of health in South Africa requires an appreciation of developments in the global political economy, international organizations such as the WHO and World Bank, and forces which operate outside of institutions. In each case, however, the specific opportunities available to actors within the country, as well as the relative power of those actors, should be given their due consideration in analysing their potential impact on health matters.

  8. Cardiomegaly in tropical Africa.

    2012-01-01

    The term "cardiomegaly" is found in 5-7% of chest X-ray film evaluations in tropical Africa. However, "cardiomegaly" is a descriptive term, devoid of any aetiological meaning. Therefore, providing information about the aetiological factors leading to heart enlargement in a group of Africans (Nigerians) was the purpose of this study. In the years 2002-2011, 170 subjects (aged 17-80 years, mean age 42 years) in whom "cardiomegaly" was revealed by chest radiographs were studied at the Madonna University Teaching Hospital, Elele. The patients underwent echocardiography, electrocardiography, and several appropriate laboratory tests. Arterial hypertension was found to be most frequently associated with heart enlargement (39.4%), followed by dilated cardiomyopathy (21.76%), endomyocardial fibrosis (14.1%), valvular defects (9.4%), cardiac enlargement in the course of sickle-cell anaemia (6.47%), and schistosomal cor pulmonale (3.52%). This study is a contribution to a better aetiological elucidation of "cardiomegaly" in the tropics and emphasizes the importance of arterial hypertension as one of its causative factors. The dire need for effective treatment of hypertensive patients becomes evident. A high prevalence of elevated blood pressure seems to reflect an impact of civilization-related factors on the African communities.

From an initiative launched by Fermilab scientist Christine Darve, the African School of Physics has grown to involve institutes and universities from all over Europe and the United States.   It’s being hosted by South Africa’s National Institute for Theoretical Physics, NITheP, at Stellenbosch, and has attracted 150 applicants from all over the continent and beyond for the 65 places available. That alone makes it a success, even before NITheP Director Frederik Scholtz uttered his words of welcome nearly three weeks ago.. When I show people the map of where CERN’s users come from, it’s gratifying to see it spanning the world, and in particular to see southern hemisphere countries starting to join the global particle physics family. Africa, however, remains notable more for the number of countries that are not involved than for those that ...

  10. Optics development in Africa

    2002-01-01

    The case study of the Office of External Activities in Cape Coast, Ghana has turned out to be a successful story in promoting research and capacity building of young scientists. The total involvement of many organizations show how laudable the idea has been. This centre has come to serve as a place to solve scientific problems as well as problems of national interest. It is foreseen that its activities can be a means to congregate African scientists to solve common problems. I think the bold step taken by OEA and some organs of ICTP, Trieste, Italy, Lund Institute of Technology, Sweden and Istituto Nazionale di Ottica Applicata, Firenze, Italy has helped up and coming African scientists to come face to face with the challenges of Laser research. Such projects seem feasible and sustainable since experts in these areas can serve as contact persons in Africa to undertake common research using optical techniques. This project has made it possible to explore various areas in optics that can be used to solve proble...

  11. Puerto del Pendulo, doubtful sound: the Malaspina expedition’s visit to New Zealand in quest of the true figure of the earth

    King, Robert J.

    2010-06-01

    Full Text Available The Malaspina expedition was assigned the task of conducting a series of experiments using the pendulum to measure the strength of gravity at different locations during the course of its voyage. The immediate objective was to establish the length of a pendulum beating at seconds at latitude 45º as the basic unit of a new universal system of measures. Although the new unit, the metre, was eventually established on a different principle, the gravity experiments carried out by the expedition resulted in useful geodesic information and incidentally led to the first charting of Doubtful Sound in New Zealand.

    La expedición Malaspina tuvo por misión realizar una serie de experimentos utilizando un péndulo para medir la fuerza de la gravedad en los diferentes lugares recorridos durante el viaje. El objetivo inmediato consistió en establecer la longitud de un péndulo oscilando durante unos segundos a una latitud de 45º como unidad básica de un nuevo sistema métrico universal. Aunque la nueva unidad, el metro, fue finalmente establecida por otro principio diferente, los experimentos que llevó a cabo la expedición sobre la gravedad proporcionaron una información geodésica muy útil y por casualidad dieron lugar al primer trazado de mapa de Doubtful Sound, en Nueva Zelanda.

  12. Cooperation: New Players in Africa

    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.

  13. Managing change in Higher Educational Institutions in South Africa: Some challenges

    Directory of Open Access Journals (Sweden)

    L. Froneman

    2003-12-01

    Full Text Available Higher Education has a vital role in developing an internationally competitive economy, a more affluent society and a sturdy democracy. The newly released National Plan for Higher Education in South Africa should recognise the current social and economic status in the country to realign its mission, and to reconsider the location and target audience of the various institutions in the country, to optimally serve the educational needs of the communities. The proposals in the National Plan, however, attempts to attain in a few years what other stabilised countries took years. That poses major challenges to education management. The aim of this paper is to evaluate some aspects of the managerial skills in the national education authorities. By analysing the National Plan, and testing the views of a number of teaching staff, the conclusion is that there are serious doubts regarding the management acumen in the educational leadership and that various important aspects are left out in the Plan.

  14. On the contemporary African experience: Towards a humanistic mode of philosophy for Africa

    2011-01-01

    Full Text Available There is no doubt that Africa today is confronted with many economic, political, social, and developmental problems. The big question and the basic challenge is therefore how best we can tackle these problems especially as we begin and forge ahead in the third millennium. This paper attempts to elucidate a fundamental role that philosophy can play in this regard. It holds that philosophy, as a discipline in the humanities, can help shape fresh ideas that are humanistic in nature in the sense that they encourage free enquiry and social agreement which are vital pillars for a fair and prosperous society; for a society without such genuine humanistic values will show many of the symptoms which are present in contemporary African societies.

    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.

    China's relations with African states have undergone significant changes in recent years. China has projected its relationship with Africa as one of equality and ‘mutual help’. Such perceptions of foreign policy stem from the Five Principles of Peaceful Coexistence and the shared experience...... of imperialist domination and economic underdevelopment. Moreover, various public statements by China's elites suggest that China is expected to play a much more prominent, even exceptional role in Africa. This purportedly entails moving beyond the hegemonic West's interventionist aid or security policies......, and is also implicitly designed to highlight the West's shortcomings in promoting African economic growth or peace. Yet where does this perception of exceptionalism come from? Why does Beijing feel that it has to play a leading role in Africa's development? How can Beijing distinguish itself from the nations...

    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)

  1. Poverty and blindness in Africa.

    Naidoo, Kovin

    2007-11-01

    Africa carries a disproportionate responsibility in terms of blindness and visual impairment. With approximately 10 per cent of the world's population, Africa has 19 per cent of the world's blindness. It is no surprise that this reality also mirrors the situation in terms of the burden of world poverty. There is an increasing recognition of the need to highlight the link between poverty, development and health care. Blindness, disabling visual impairment and the overall lack of eye-care services are too often the result of social, economic and developmental challenges of the developing world. The state of eye care in Africa stands in alarming contrast to that in the rest of the world. Poor practitioner-to-patient ratios, absence of eye-care personnel, inadequate facilities, poor state funding and a lack of educational programs are the hallmarks of eye care in Africa, with preventable and treatable conditions being the leading cause of blindness. Eye diseases causing preventable blindness are often the result of a combination of factors such as poverty, lack of education and inadequate health-care services. The challenge that Vision 2020 has set itself in Africa is enormous. Africa is not a homogenous entity, the inter- and intra-country differences in economic development, prevalence of disease, delivery infrastructure and human resources amplify the challenges of meeting eye-care needs. The successful implementation of Vision 2020 programs will be hindered without the development of a comprehensive, co-ordinated strategy that is cognisant of the differences that exist and the need for comprehensive solutions that are rooted in the economic and political realities of the continent as well as the individual countries and regions within countries. This strategy should recognise the need for economic growth that results in greater state funded eye-care services that focus on health promotion to ensure the prevention of eye disease, the development of eye clinics in

    Changing Chemistry in a Changing Climate: Human and Natural Impacts Over Southern Africa (C4-SAR); Midrand, South Africa, 31 May to 3 June 2011 During the southern African dry season, regional haze from mixed industrial pollution, biomass burning aerosol and gases from domestic and grassland fires, and biogenic sources from plants and soils is worsened by a semipermanent atmospheric gyre over the subcontinent. These factors were a driver of several major international field campaigns in the 1990s and early 2000s and attracted many scientists to the region. Some researchers were interested in understanding fundamental processes governing chemistry of the atmosphere and interaction with climate change. Others found favorable conditions for evaluating satellite- derived measurements of atmospheric properties and a changing land surface. With that background in mind a workshop on atmospheric chemistry was held in South Africa. Sponsored by the International Commission on Atmospheric Chemistry and Global Pollution (ICACGP; http://www.icacgp.org/), the workshop received generous support from Eskom, the South African power utility; and the Climatology Research Group of the University of the Witwatersrand, Johannesburg, South Africa.

  6. Plasmodium vivax Transmission in Africa.

    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

    2010-11-01

    A seminal case study by Festinger found, paradoxically, that evidence that disconfirmed religious beliefs increased individuals' tendency to proselytize to others. Although this finding is renowned, surprisingly, it has never been subjected to experimental scrutiny and is open to multiple interpretations. We examined a general form of the question first posed by Festinger, namely, how does shaken confidence influence advocacy? Across three experiments, people whose confidence in closely held beliefs was undermined engaged in more advocacy of their beliefs (as measured by both advocacy effort and intention to advocate) than did people whose confidence was not undermined. The effect was attenuated when individuals affirmed their beliefs, and was moderated by both importance of the belief and open-mindedness of a message recipient. These findings not only have implications for the results of Festinger's seminal study, but also offer new insights into people's motives for advocating their beliefs.

    Lyme disease is a tick-borne illness endemic to Minnesota that can have potentially severe complications. As the incidence of Lyme disease continues to increase, it is important for physicians in Minnesota to become familiar with its clinical aspects, including the concept of "chronic Lyme disease." Chronic Lyme disease is a misnomer that is often applied to patients with nonspecific presentations who may or may not have a history of infection with Borrelia burgdorferi, the agent that causes Lyme disease. When a patient does present with persistent nonspecific symptoms attributed to chronic Lyme disease, clinicians should ascertain the presence of objective manifestations, obtain laboratory results, and get a history of tick exposure. If active infection with B. burgdorferi is unlikely, they should avoid prescribing empiric antibiotic therapy and instead thoroughly evaluate the patient for other possible causes of the complaints and recommend appropriate care.

    Burn injuries in Africa are common with between 300,000 and 17.5 million children under 5 years sustaining burn injuries annually, resulting in a high estimated fatality rate. These burns are largely environmentally conditioned and therefore preventable. The Western Cape Province in South Africa can be regarded as a prototype of paediatric burns seen on the continent, with large numbers, high morbidity and mortality rates and an area inclusive of all factors contributing to this extraordinary burden of injury. Most of the mechanisms to prevent burns are not easily modified due to the restraint of low socio-economic homes, overcrowding, unsafe appliances, multiple and complex daily demands on families and multiple psycho-social stressors. Children <4 years are at highest risk of burns with an average annual rate of 6.0/10,000 child-years. Burn care in South Africa is predominantly emergency driven and variable in terms of organization, clinical management, facilities and staffing. Various treatment strategies were introduced. The management of HIV positive children poses a problem, as well as the conflict of achieving equity of burn care for all children. Without alleviating poverty, developing minimum standards for housing, burn education, safe appliances and legislation, we will not be able to reduce the "curse of poor people" and will continue to treat the consequences.

    The previously gullible and apathetic South African public, generally speaking, is lately becoming increasingly rights-based sophisticated. Patients are no longer accepting inferior quality work and have become more knowledgeable especially regarding the expected skills and professional conduct of dentists. The present study examined archival material as published between 2007 and 2013 of penalties against ethical misconduct. It was found that the majority of ethical transgressions took place in urban settings and the most predominant transgression was charging for services not performed and submitting these claims to medical aids as well as performing sub-optimal interventions. Legally a practitioner who performs such acts may be held liable for the damage or injury suffered by the patient as a consequence of these acts, on the basis of negligence. Penalties imposed by the Health Professions Council of South Africa vary between 5,000 Rand and 15,000 Rand, as well as suspensions of between 9 to 12 months. It is doubtful that transgressors would change their behaviour in the light of the present Continuous Professional Development programmes where attendance is really the only prerequisite and not moral reflection. This study recommends that the Health Professions Council of South Africa need to re-evaluate the effectiveness of their ethical training programmes and adapt the model to incorporate more inclusive learning.

    Long-range and inter-hemispheric transport of atmospheric aerosols over equatorial Africa has received little attention so far. Most aerosol studies in the region have focussed on emissions from rain forest and savanna (both natural and biomass burning) and were carried out in the framework of programs such as DECAFE (Dynamique et Chimie Atmospherique en Foret Equatoriale) and FOS (Fires of Savanna). Considering the importance of this topic, aerosols samples were measured in different seasons at 4420 meters on Mt Kenya and on the equator. The study is based on continuous aerosol sampling on a two stage (fine and coarse) streaker sampler and elemental analysis by Particle Induced X-ray Emission. Continuous samples were collected for two seasons coinciding with late austral winter and early austral spring of 1997 and austral summer of 1998. Source area identification is by trajectory analysis and sources types by statistical techniques. Major meridional transports of material are observed with fine-fraction silicon (31 to 68 %) in aeolian dust and anthropogenic sulfur (9 to 18 %) being the major constituents of the total aerosol loading for the two seasons. Marine aerosol chlorine (4 to 6 %), potassium (3 to 5 %) and iron (1 to 2 %) make up the important components of the total material transport over Kenya. Minimum sulfur fluxes are associated with recirculation of sulfur-free air over equatorial Africa, while maximum sulfur concentrations are observed following passage over the industrial heartland of South Africa or transport over the Zambian/Congo Copperbelt. Chlorine is advected from the ocean and is accompanied by aeolian dust recirculating back to land from mid-oceanic regions. Biomass burning products are transported from the horn of Africa. Mineral dust from the Sahara is transported towards the Far East and then transported back within equatorial easterlies to Mt Kenya. This was observed during austral summer and coincided with the dying phase of 1997/98 El

    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.

  18. Africa and Precambrian biological evolution

    Directory of Open Access Journals (Sweden)

    A. H. Knoll

    1983-12-01

    Full Text Available African sedimentary rocks and their contained fossils have played a fundamental role in the unravelling of Precambrian biological history. Various lines of evidence including stromatolites, filamentous and coccoidal microfossils, stable isotope ratios, organic carbon distribution, and oxide facies iron formation suggest that a complex prokaryotic ecosystem fueled by photosynthesis, and perhaps including aerobic photoautotrophs, existed as early as 3 500 m.y. ago. The primary sources of data on early Archean life are rock sequences in southern Africa and Australia. The diversity of later Archean (ca. 2 700 m.y. communities is attested to by abundant and varied stromatolites found in Zimbabwe. The extensive growth and consolidation of continents that heralded the Proterozoic Eon had profound effects on the earth’s biota. Primary productivity must have increased substantially, resulting in the establishment of an 02-rich atmosphere, and, subsequently, the radiation of aerobic respirers. Southern African sequences provide critical evidence bearing on this crust/atmosphere/biota interaction; however, the best known microfossils of this age come from North America. Upper Proterozoic sedimentary rocks abound in Africa. Stromatolites from northwestern Africa have been well studied; however, microfossil occurrences remain but sketchily described. Contemporaneous sequences from Scandinavia and Australia document the initial radiation of eukaryotes in the planktonic realm, as well as a terminal Precambrian episode of extinction among plankters. Early heterotrophic protists are known from several continents. The Nama Group of South West Africa/Namibia contains important evidence of early invertebrates. In general, Precambrian evolution can be viewed as a series of increasingly elevated biological plateaus connected by steps marking relatively short periods of evolutionary innovation and radiation. With each step, communities have increased in complexity

    Pale green vegetation and red-brown deserts dominate this MODIS image of Namibia (left), Botswana (upper right), and the Republic of South Africa (bottom) acquired on June3, 2002. In central Namibia the mountainous terrain of Namaqualand is sandwiched between the Namib Desert on the Atlantic Coast and the Kalahari Desert to the interior, where white dots mark the location of small, impermanent lakes and ponds. Namaqualand is home to numerous rare succulent plants that can survive on the region.s scant rainfall as well as fog that blows in off the ocean. Namaqualand extends south of the Orange River, which runs along the border of Namibia and South Africa and into that country.s Northern Cape region. The Orange River extends almost all the way back through the country, and where it makes a sharp southward dip in this image (at lower right), it runs through the Asbestos Mountains, names for the naturally-occurring asbestos they contain. In southwestern South Africa, high plateaus, such as the Great Karoo become mountain ridges near the coast, and the city of Cape Town is visible as a grayish area of pixels on the north shores of the horseshoe-shaped False Bay at the Cape of Good Hope.

  4. Administrative bias in South Africa

    E S Nwauche

    2005-01-01

    Full Text Available This article reviews the interpretation of section 6(2(aii of the Promotion of Administrative Justice Act which makes an administrator “biased or reasonably suspected of bias” a ground of judicial review. In this regard, the paper reviews the determination of administrative bias in South Africa especially highlighting the concept of institutional bias. The paper notes that inspite of the formulation of the bias ground of review the test for administrative bias is the reasonable apprehension test laid down in the case of President of South Africa v South African Rugby Football Union(2 which on close examination is not the same thing. Accordingly the paper urges an alternative interpretation that is based on the reasonable suspicion test enunciated in BTR Industries South Africa (Pty Ltd v Metal and Allied Workers Union and R v Roberts. Within this context, the paper constructs a model for interpreting the bias ground of review that combines the reasonable suspicion test as interpreted in BTR Industries and R v Roberts, the possibility of the waiver of administrative bias, the curative mechanism of administrative appeal as well as some level of judicial review exemplified by the jurisprudence of article 6(1 of the European Convention of Human Rights, especially in the light of the contemplation of the South African Magistrate Court as a jurisdictional route of judicial review.

By tracing the origins of the Christian faith in both North and sub-Saharan Africa (including, North-Central and West Africa, this paper seeks to show that Christianity has been in Africa virtually since its inception and that the continent� s own adherents to this faith played an important role in the formation and advance of Christianity elsewhere. Moreover, Christianity in Africa can be found almost everywhere on the continent and indigenous varieties of the tradition developed which allowed it to become as part of Africa as African traditional religions.

  8. 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.

  9. Emigration dynamics in southern Africa.

    Science.gov (United States)

    Milazi, D

    1995-01-01

    This review of the dynamics of international migration in Southern Africa focuses on four aspects of labor migration: 1) while migrant workers suffer from discrimination and lack of protection, there are few alternatives for them; 2) the regulations imposed by the Chamber of Mines in South Africa favor the mining industry at the expense of the workers; 3) worker supplier states have few options for negotiating a commercialized migration policy to achieve economic benefits; and 4) foreign mine workers must unionize in order to escape perpetual subordination. The review opens with a consideration of how migrant mine workers from Botswana, Lesotho, and Swaziland have provided a source of cheap labor which has enhanced the economic prosperity of South Africa. The role of the Chamber of Mines in regulating the supply of labor and employment policy for its members is described. Attention is then turned to Lesotho where land pressure has exacerbated poverty levels. Large-scale migration has led the citizens of Lesotho to consider it a place to live or retire to, not a place to work. Labor migration from Lesotho is organized, is supported by the government, is recurrent, and remains a viable alternative despite faltering demand. The discussion of Lesotho includes a consideration of its political, economic, and demographic situation as well as of ecological factors. Briefer analyses are then provided for Botswana, Swaziland, and Mozambique. The receiving country, South Africa, is shown to be suffering a decline in economic growth which is marked by widespread unemployment. More than 250,000 Whites are prospective emigrants from South Africa. After considering the issues surrounding refugees, regional concerns created by changing economic and political scenarios, and labor strategies which could be adopted by supplier states, the report reiterates a series of recommendations which arose from two major conferences on the problem of unemployment. It is concluded that the

    After functioning for some time in an increasingly regulated and structured environment in dealing with the private sector in South Africa, it was important to Government, to carefully review the terminology used in this evolving playing field. As the definitions and mechanisms impacting on this form of interaction became clear, it was essential to find a broader definition to encompass all forms of commercial intervention between the two sectors. In preparation for the first South African National Health Summit during 2001, the term public private interaction became a general term used in this context. In the South African healthcare sectors this term is used specifically to indicate that all forms of interaction between the two sectors should be considered, rather than merely focussing on specific Public Private Partnerships (PPPs), that have a much more narrow definition. Recent health policy documents in South Africa all stress four key goals--equity, coherence, quality of care and efficiency--which provide a useful basis for decision-making about PPIs. The range of public-private interactions that may support or constrain the South African health system's development are set within the overall public/private mix of the country. In developing an equitable, efficient, coherent and high quality health system in South Africa, there is considerable potential for constructive engagement (collaboration and co-operation) between the public and the private health care sectors. Both sectors should embrace this opportunity and therefore it is useful to propose some basic guidelines for engagement based on the vision and goals of the national health system. In deciding whether or not to pursue any new PPI within the health sector, or in evaluating whether an existing PPI should continue or be revised, it is necessary to assess its merits in relation to the achievement of health system goals.

  19. How Environmental "Merchants of Doubt" Use Peer-Reviewed Publication as a Means to Commandeer Scientific Debate: A Case Study of a Publishing Problem.

    Science.gov (United States)

    Siegel, D. I.

    2015-12-01

    This year, the USEPA reported no systemic problem with respect to pollution of potable waters by solutes or natural gas resulting from unconventional drilling for oil and gas, despite attempts by anti-fracking opponents to frighten the public about water pollution from rare circumstances (much as those who have cherry- picked climate data to suggest burning fossil fuels does not affect climate). Scientific "merchants of doubt" have figured out how to use peer-reviewed papers to advocate their bias, regardless of the side for which they advocate. I present a personal example. Prior to the EPA report, authors of a highly-cited peer-reviewed paper argued that more dissolved methane than usual should be expected in ground water located close to unconventional gas wells. This paper figured prominently in the New York State's recent ban on fracking. To test the reproducibility of this conclusion, colleagues and I redid the study but by sampling ~13,000 NE Pennsylvania domestic wells, densely arrayed near ~800 gas wells. Not surprising, we found no systemic relationship between methane in drinking water and proximity to gas wells; failed gas wells actually are rare. The peer reviewed system of publication has been broken for years, because of continual pressure to publish more to achieve academic success coupled to a flood of international submissions. Editors routinely have a difficult time finding senior scientists to agree to review papers, and so they wind up relying more on reviewers suggested by authors, who can and have gamed the peer review system through it. To resolve this problem, I suggest that journal editors be more far more draconian before releasing papers for review and that they enforce clear rubrics to insure that reviewers address reviews properly. Finally, conflict of interest disclosure needs to be clearer, since common assumption that bias inherently evolves from funded research outside of Federal and non-profit organizations, appears to be, at

    Full Text Available Concerns about the environmental and ecological consequences of hydraulic fracturing have accompanied the shale boom in developed countries at the forefront of shale exploration and production. These environmental and ecological consequences may be of even greater concern in developing countries with less governance capacity. We present a conceptual framework that specifies several variables that are expected to contribute to sustainable hydraulic fracturing. We use the framework to characterize prospects for sustainable hydraulic fracturing in South Africa and Botswana. The framework and evidence clarifies the institutional capacity and institutional challenges confronting the sub-Saharan African countries as extraction of natural resources using hydraulic fracturing begins in earnest.

    Recent discussion about the increase in international research collaboration suggests a comprehensive global network centred around a group of core countries and driven by generic socio-economic factors where the global system influences all national and institutional outcomes. In counterpoint, we demonstrate that the collaboration pattern for countries in Africa is far from universal. Instead, it exhibits layers of internal clusters and external links that are explained not by monotypic global influences but by regional geography and, perhaps even more strongly, by history, culture and language. Analysis of these bottom-up, subjective, human factors is required in order to provide the fuller explanation useful for policy and management purposes.

    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.

    In 2011, IRENA will start developing scenarios and strategies for Africa. This is a pilot study for a project that will ultimately encompass the whole world. The selection of Africa first indicates the priority that the IRENA work programme places on the continent. In the framework of the 2011 IRENA work programme, the analysis of scenarios and strategies will feed into the renewables readiness assessment, which will assess policy priorities and best practices in renewable energy policy-making. This, in turn, will be the basis for financing investment and capacity building activities. Energy policy advice must consider issues, such as the structure of energy supply and demand, the past and future energy trends, renewable energy resources, energy economics and technology access. Scenarios and strategies are key tools for such an analysis. Regional and national differences must be considered and individual sectors and end-use categories further analysed. These include power generation, cooking, heating, industrial process heat, and transport. Urban and rural solutions will be dealt with separately, as well as centralised and decentralised solutions. The analysis will cover issues, such as potentials, technology, supply chains and investment needs.

    Southern Africa has some of the world's best sites for air Cherenkov telescopes. South Africa has only one viable site, which is south of Sutherland and also close to the Southern African Large Telescope (SALT). This site has very good infrastructure and is easy to access, but only 47% of the night-time has a cloudless sky usable for observations. Namibia, which already hosts the H.E.S.S telescope, has a number of potential sites with much less cloud coverage. The H.E.S.S. site is one of the highest of these sites at 1840 m a.s.l. with about 64% of the night-time cloudless. It also has very low night sky background levels and is relatively close (about 100 km) to Windhoek. Moving further away from Windhoek to the south, the cloud coverage and artificial night sky brightness becomes even less, with the site at Kuibis (between Keetmanshoop and Luderitz) at 1640 m a.s.l. having clear night skies 73% of the time. Even though this site seems remote (being 660 km from Windhoek by road), it is close to the national ...

  6. Human origins: Out of Africa

    Tattersall, Ian

    2009-01-01

    Our species, Homo sapiens, is highly autapomorphic (uniquely derived) among hominids in the structure of its skull and postcranial skeleton. It is also sharply distinguished from other organisms by its unique symbolic mode of cognition. The fossil and archaeological records combine to show fairly clearly that our physical and cognitive attributes both first appeared in Africa, but at different times. Essentially modern bony conformation was established in that continent by the 200–150 Ka range (a dating in good agreement with dates for the origin of H. sapiens derived from modern molecular diversity). The event concerned was apparently short-term because it is essentially unanticipated in the fossil record. In contrast, the first convincing stirrings of symbolic behavior are not currently detectable until (possibly well) after 100 Ka. The radical reorganization of gene expression that underwrote the distinctive physical appearance of H. sapiens was probably also responsible for the neural substrate that permits symbolic cognition. This exaptively acquired potential lay unexploited until it was “discovered” via a cultural stimulus, plausibly the invention of language. Modern humans appear to have definitively exited Africa to populate the rest of the globe only after both their physical and cognitive peculiarities had been acquired within that continent.

Se presenta una base comparativa para los cuatro principales métodos de determinación de HdC actualmente vigentes en el mercado y se propone un método denominado Abaco para la contabilización de emisiones de CO2 equivalente , que permite identificar las características comunes de estos métodos. Todo esto puede servir de base en la toma de decisiones gerenciales para adoptar una determinada metodología. Se concluye que d e mantenerse la falta de claridad y comparabilidad en la determinación de emisiones podría provocar la pérdida de una gran oportunidad para lanzar una nueva economía medio-ambientalmente sostenible.In this second part of the series, the viewpoint of the enterprises and their position with respect to the implementation of carbon footprint (CFP quantification.

A comparison of the main four methods currently used for determining the CFP and a method named Abacus for quantifying emissions of equivalent CO2 that allows identifying the common characteristics to all of them. All this can serve as basis for decision-making to adopt a given methodology. It is concluded that if the present situation of confusion of the different approaches to quantify the CFP continues, the companies and governments are loosing a great opportunity to arrive to a new environmentally sustainable economy.

    2011-01-01

    During the southern African dry season, regional haze from mixed industrial pollution, biomass burning aerosol and gases from domestic and grassland fires, and biogenic sources from plants and soils is worsened by a semi-permanent atmosphere gyre over the subcontinent. These factors were a driver of several major international field campaigns in the 1990s and early 2000s, and attracted many scientists to the region. Some researchers were interested in understanding fundamental processes governing chemistry of the atmosphere and interaction with climate change. Others found favorable conditions for evaluating satellite-derived measurements of atmospheric properties and a changing land surface. With that background in mind a workshop on atmospheric chemistry was held in South Africa. Sponsored by the International Commission for Atmospheric Chemistry and Global Pollution (ICACGP; http://www.icacgp.org/), the workshop received generous support from the South African power utility, Eskom, and the Climatology Research Group of the University of the Witwatersrand, Johannesburg, South Africa. The purpose of the workshop was to review some earlier findings as well as more recent findings on southern African climate vulnerability, chemical changes due to urbanization, land-use modification, and how these factors interact. Originally proposed by John Burrows, president of ICACGP, the workshop was the first ICACGP regional workshop to study the interaction of air pollution with global chemical and climate change. Organized locally by the University of the Witwatersrand, the workshop attracted more than 60 delegates from South Africa, Mozambique, Botswana, Zimbabwe, France, Germany, Canada, and the United States. More than 30 presentations were given, exploring both retrospective and prospective aspects of the science. In several talks, attention was focused on southern African chemistry, atmospheric pollution monitoring, and climate processes as they were studied in the field

    2005-01-01

    The comparative review of 2 representative segments of Africa continental margin: the equatorial western Africa and the SW Africa margins, helps in analysing the main controlling factors on their development. Early Cretaceous active rifting S of the Walvis Ridge resulted in the formation of the SW Africa volcanic margin. The non-volcanic rifting N of the Walvis ridge, led to the formation of the equatorial western Africa margin, with thick and extensive, synrift basins. Regressive erosion of SW Africa prominent shoulder uplift accounts for high clastic sedimentation rate in Late Cretaceous - Eocene, while dominant carbonate production on equatorial western Africa shelf suggests little erosion of a low hinterland. The early Oligocene climate change had contrasted response in both margins. Emplacement of the Congo deep-sea fan reflects increased erosion in equatorial Africa, under the influence of wet climate, whereas establishment of an arid climate over SW Africa induced a drastic decrease of denudation, and ...

    Programs using remote sensing to obtain geologic information in Africa are reviewed. Studies include the use of Landsat MSS data to evaluate petroleum resources in sedimentary rock terrains in Kenya and Sudan and the use of Landsat TM 30-m resolution data to search for mineral deposits in an ophiolite complex in Oman. Digitally enhanced multispectral SPOT data at a scale of 1:62,000 were used to map folds, faults, diapirs, bedding attitudes, and stratigraphic units in the Atlas Mountains in northern Algeria. In another study, SIR-A data over a vegetated and faulted area of Sierra Leone were compared with data collected by the Landsat MSS and TM systems. It was found that the lineaments on the SIR-A data were more easily detected.

    2009-06-15

    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.

    The review presents the epidemiology of leishmaniasis in the Eastern Africa region. We searched PUB MED and MEDLINE with several key words-namely,"leishmaniasis";"cutaneous"," diffuse cutaneous"," mucosal", and "visceral leishmaniasis";"kala azar" and "post kala azar dermal leishmaniasis"-for recont clinical and basic science articles related to leishmaniasis in countries in the Eastern Africa region. Poverty, wars, conflicts and migration have significantly aggravated leishmaniases in Eastern Africa. Of particular concern is the increasing incidence of Leishmania-HIV co-infection in Ethiopia where 20--40% of the persons affected by visceral leishmaniasis are HIV-co-infected. Sudan has the highest prevalence rate of post kala-azar dermal leishmaniasis(PKDL) in the world, a skin complication of visceral leishmaniasis(VL) that mainly afflicts children below age ten. In view of its spread to previously non-endemic areas and an increase in imported cases, leishmaniasis in Eastern Africa should be considered a health emergency.

    1999-03-01

    Dry cargo continues to form the backbone of South Africa`s commodities trades, comprising more than 70% of overall import and export activity. Despite economic stagnation in many global markets and poor prospects for any significant recovery in prices, most of South Africa`s dry bulk ports have experienced sustained tonnage levels in 1998, and are focusing on facility improvements to meet future growth expectation.

  13. 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.

  14. Food allergy in Africa: myth or reality?

    Kung, Shiang-Ju; Steenhoff, Andrew P; Gray, Claudia

    2014-06-01

    Food allergy has been traditionally perceived as being rare in Africa. However, the prevalence of other allergic manifestations such as asthma and atopic dermatitis continue to rise in the higher-income African countries. Since the food allergy epidemic in westernized countries has lagged behind that of allergic respiratory conditions, we hypothesize that food allergy is increasing in Africa. This article systematically reviews the evidence for food allergy in Africa, obtained through searching databases including PubMed, Medline, MD Consult, and scholarly Google. Articles are divided into categories based on strength of methodological diagnosis of food allergy. Information was found for 11 African countries: Botswana, Democratic Republic of Congo, Ghana, Kenya, Morocco, Mozambique, Nigeria, South Africa, Tanzania, Tunisia, and Zimbabwe. Most studies reflect sensitization to food or self-reported symptoms. However, a few studies had more stringent diagnostic testing that is convincing for food allergy, mostly conducted in South Africa. Apart from the foods that commonly cause allergy in westernized countries, other regionally significant or novel food allergens may include pineapple (Ghana), okra (Nigeria), and mopane worm (Botswana). Food allergy is definitely an emerging disease in Africa and resources need to be diverted to study, diagnose, treat, and prevent this important disease.

  16. The quest for safe drinking water: an example from Guinea-Bissau (West Africa).

    2007-07-01

    While humans require water for life, one-sixth of our species lives without access to safe water. In Africa, the situation is particularly acute because of global warming, the progression of the Sahara desert, civil unrest and poor governance, population growth, migration and poverty. In rural areas, the lack of adequate safe water and sanitary infrastructures leaves millions with doubtful water quality, increasing the harshness of daily life. In this paper, a pilot study was conducted during the wet season on Bolama Island (Guinea-Bissau, West Africa), a UNESCO Man and the Biosphere Reserve. Twenty-eight shallow wells, supplying water to most of the population, were sampled for microbiological, physical and chemical water quality characteristics. A ten-parameter water quality index (WQI) adapted to tropical conditions was applied to compare the different wells. About 79% of the wells showed moderate to heavy fecal contamination. From the surveyed parameters, it was found that chemical contamination was less important, although all samples were acidic, with the pH averaging 5.12+/-0.08. The WQI was 43+/-4% (0%-worst; 100%-best quality), showing that the water from the majority of wells was polluted but should be suitable for domestic use after appropriate treatment. At the onset of the wet season, diarrhea represented 11.5% of all medical cases, 92.5% of which were children aged <15. This paper suggests inexpensive steps to reduce the fecal contamination and control the pH in order to increase the potability of the well water and, concomitantly, to raise the living standards of the population in one of the poorest countries of the world.

  17. South Africa faces coke shortage

    Iscor Vanderbijlpark in South Africa may need to import substantial tonnages of coking coal as a result of increasing quality demands on coke at Vanderbiljpark (to support the recently installed PCI process) as well as the Newcastle works. Availability of coke is not only a problem for the South African steel industry but is a global problem as the production of coke in Western countries has declined over the past three years. A massive expansion in coke-making capacity is happening in China but the Chinese beehive ovens create serious pollution problems. A world shortage of coke of 30 million t/y by 2005 is estimated, rising to over 60 million t/y by 2010 of no new capacity is created. Steelmakers have succeeded in reducing their consumption of coke, by pulverised coal injection by better distribution of components in the furnace shaft and by decline in use of the blast furnace-basic oxygen furnace route, but the industry is still facing serious shortages of coke.

    Full Text Available Despite their significance in soil ecosystems and their use for investigations of soil ecosystem functioning and in bioindication elsewhere, springtails (Collembola have not been well investigated in South Africa. Early recognition of their role in soil systems and sporadic systematic work has essentially characterised knowledge of the southern African fauna for some time. The situation is now changing as a consequence of systematic and ecological work on springtails. To date this research has focused mostly on the Cape Floristic Region and has revealed a much more diverse springtail fauna than previously known (136 identifiable species and an estimated 300 species for the Cape Floristic Region in total, including radiations in genera such as the isotomid Cryptopygus. Quantitative ecological work has shown that alpha diversity can be estimated readily and that the group may be useful for demonstrating land use impacts on soil biodiversity. Moreover, this ecological work has revealed that some disturbed sites, such as those dominated by Galenia africana, may be dominated by invasive springtail species. Investigation of the soil fauna involved in decomposition in Renosterveld and Fynbos has also revealed that biological decomposition has likely been underestimated in these vegetation types, and that the role of fire as the presumed predominant source of nutrient return to the soil may have to be re-examined. Ongoing research on the springtails will provide the information necessary for understanding and conserving soils: one of southern Africa’s major natural assets.

These two regions are presented separately in this volume and its sister publication. The country profiles combine elements of IRENA analysis with the latest information available from a vast array of sources in order to give a brief yet comprehensive and up-to-date picture of the situation of renewable energy that includes energy supply, electrical capacity, energy access, policies, targets, investment climate, projects and endowment in renewable energy resources. Because of the different timelines of these sources, data presented here refer to years between 2008 and 2012. Data availability also differs from country to country, which makes comparison with a wider regional group possible only for the year for which figures are available for all the members of the group; while this may not be the most recent year, the differences between countries, regions and the world remain striking. The current country profiles are just a starting point; they will be extended upon with new indicators to make them more informative, and maintained as a live product on the IRENA website as a key source of information on renewable energy.

  2. Occurrences and Effects of Drought across Africa

    Science.gov (United States)

    Mwangi, M. N.

    2009-12-01

    Drought is a common occurrence in Africa and its effects vary temporally and spatially across the continent. The objective of this paper is to synthesize available information on droughts in Africa in order to discern emerging trends vis-à-vis spatiotemporal occurrences, impacts and adaptation. Drought forcings in the Sahelian region and southern Africa are predominately related to the passage of mid-latitude air masses while in locations near the equator is strongly linked to the position of ITCZ, except perhaps in the deserts where albedo may predominate. The review shows that drought occurrences have increased both temporally and spatially; its effects on the society vary across scales, and are influenced by political, economic, social, cultural, and ecological factors. The drought occurrence and its impacts varied spatially and temporally. The effect of drought also varied with socioeconomic sector; agriculture and pastoralism were the widely reported. The greater horn of Africa, specifically Kenya, has the most continuous record of droughts. The synthesis also reveals that a suite of drought adaptation strategies exists at the local scale; in contrasts, at the aggregate scale, coping strategies are scarce. Drought management tailored for specific livelihood system or societies are non-existent. The study found that occurrence of drought alongside issues related to the multiscale political economy affect the viability of most adaptation strategies used by societies across Africa. Drought management has been silent on the social, political, and economic dimensions that reasonably aggravate the vulnerability of lives and livelihood systems to this climatic hazard. The effect of drought and social pressures is relational and simultaneous to such a degree that differential vulnerability among communities across Africa is to be expected. Although scenarios about rainfall and drought vis-à-vis Africa are largely contested there is a general indication that most

  3. Managing the wetlands. People and rivers: Africa.

    Science.gov (United States)

    Dugan, P

    1993-01-01

    At the current population growth rate in Africa, the population will reach 1 billion by 2010. Water is needed to sustain these people, yet rainfall in Africa is erratic. Africans are already confronting a shortage of freshwater. Agriculture supports 66% of the population of sub-Saharan Africa. Sound agricultural development is needed to curb rural-urban migration, but a constant supply of freshwater is essential. Major rivers (the Limpopo in southern Africa and the Save/Sabi in Zimbabwe and Mozambique) now flow only seasonally. The flows of the Chari-Logona, the Nile, and the Zambezi are falling. Continual mismanagement of Africa's river basins coupled with current projections of global climate change will expand desiccation. All but the White Nile and the Zaire rivers flood seasonally every year, thereby expanding Africa's wetlands. Wetlands have been targeted for development projects (e.g., hydroelectric projects and large dams), largely to meet urban-industrial demands. Development planners tend to ignore the economic value of the wetlands. For example, the Niger Inland Delta sustains 550,000 people, 1 million cattle, and 1 million sheep. Wetlands replenish ground water and serve as natural irrigation. River basin planning often results in environmentally disastrous schemes which do not understand local management practices. Hydrologists, engineers, geologists, and economics design these schemes, but sociologists, anthropologists, and development experts should be included. The unfinished Jonglei Canal in southern Sudan would have adversely affected 400,000 pastoralists. The Volta River Authority's Akosombo Dam displaced 84,000 people and flooded the most productive agricultural land in Ghana. A sustainable future in Africa depends on understanding the interactions of human uses and the ways in which they relate to the natural variations in river flow. The IUCN Wetlands Programme, based on the principles of the World Conservation Strategy, is working with

    2011-01-01

    While the Green Revolution has been successful in some regions like South and East Asia, it could hardly address any achievement in Sub-Saharan Africa (SSA). This paper tries to draw a picture on lessons learned from the failures of this revolution that should be taken into account before implementing the so-called Gene Revolution in the SSA region. After scrutinizing the failures and the pros and cons of GM crops in the region, the paper introduces some potentials for improving the malnutrition situation in SSA through launching a successful GM technology. However, it remains doubtful whether this technology can improve the situation of small-scale farmers as long as they receive no financial support from their national governments. Therefore, before any intervention, the socio-economic and environmental impacts of GM technology need to be carefully addressed in the framework of a series of risk assessment studies. Besides, some sort of multi-stakeholder dialog (from small-scale farmers to consumers) involving public-private sector and non-governmental organizations should be heated up at both national and regional levels with regard to the myths and truths of this technology.

    Full Text Available North Africa has known various colonizations which in contact with indigenous ones have given the area a special character. One continuing presence since antiquity is that of the Berbers, or the Imazighen, the indigenous population of the area. In this article an attempt is made to shed light on the status of the language and culture of the Imazighen, and in particular on the recent calls for official recognition of the Amazigh language in the constitutions of the two countries with the highest presence of Imazighen, namely Morocco and Algeria. Although some recent developments, like the teaching of the Amazigh language in primary schools, give reason enough to be optimistic about the future of the indigenous language and culture, a closer look at the ideological background of pan Arab-nationalists casts doubts on any serious government intentions to guarantee the maintenance and development of the Amazigh language and culture. This ideology will be brought to light by contrasting the constitutional rights that some Muslim and/or African countries grant to their citizens who speak different languages than the official one(s.

    2010-06-01

    Full Text Available Emerging zoonotic diseases have assumed increasing fundamental importance in both public and animal health, as the last few years have seen a steady increase of new cases, each emerging from an unsuspected geographic area and causing serious problems, often leading to mortalities among animals and humans. The reasons for disease emergence or re-emergence are multiple and include certain major factors, such as expansion of the human population, climate change and globalisation of trade. Further contributing issues, such as the increased movement of animal species, microbial evolution, ecological disruption, changes in human behaviour, all imply that emerging diseases will not only continue to occur, but the rate of their emergence will also increase. These will constitute constraints for the attainment of the Millennium Development Goals by African Governments by 2015. There is no doubt that the current trend calls for more and stronger partnerships between national and international organisations, veterinary and medical communities, environmentalists, academics and policy-makers of various governments on the continent within the context of the global ‘One Health’ movement. This article attempts to analyse the impact of emerging diseases and the implications for the achievement of the Millennium Development Goals in Africa by the year 2015.

    2012-05-01

    The care of children with malignant solid tumors in sub-Saharan Africa is compromised by resource deficiencies that range from inadequate healthcare budgets and a paucity of appropriately trained personnel, to scarce laboratory facilities and inconsistent drug supplies. Patients face difficulties accessing healthcare, affording investigational and treatment protocols, and attending follow-up. Children routinely present with advanced local and metastatic disease and many children cannot be offered any effective treatment. Additionally, multiple comorbidities, including malaria, tuberculosis, and HIV when added to acute on chronic malnutrition, compound treatment-related toxicities. Survival rates are poor. Pediatric surgical oncology is not yet regarded as a health care priority by governments struggling to achieve their millennium goals. The patterns of childhood solid malignant tumors in Africa are discussed, and the difficulties encountered in their management are highlighted. Three pediatric surgeons from different regions of Africa reflect on their experiences and review the available literature. The overall incidence of pediatric solid malignant tumor is difficult to estimate in Africa because of lack of vital hospital statistics and national cancer registries in most of countries. The reported incidences vary between 5% and 15.5% of all malignant tumors. Throughout the continent, patterns of malignant disease vary with an obvious increase in the prevalence of Burkitt lymphoma (BL) and Kaposi sarcoma in response-increased prevalence of HIV disease. In northern Africa, the most common malignant tumor is leukemia, followed by brain tumors and nephroblastoma or neuroblastoma. In sub-Saharan countries, BL is the commonest tumor followed by nephroblastoma, non-Hodgkin lymphoma, and rhabdomyosarcoma. The overall 5-years survival varied between 5% (in Côte d'Ivoire before 2001) to 34% in Egypt and up to 70% in South Africa. In many reports, the survival rate of

  8. Africa and the global carbon cycle

    Denning A Scott

    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.

  9. INFORMATION-BASED CONFLICT IN AFRICA

    Directory of Open Access Journals (Sweden)

    Brett Van Niekerk

    2013-11-01

    Full Text Available For a long time, the African continent was regarded as the ‘Dark Continent’. The rapid assimilation of information technologies into the African economies has placed Africa firmly on a trajectory that will see it compete and integrate with the developed world. As nations and organisations become more information-centric, it is natural that conflicts and competition amongst the various nations or organisations will become increasingly information-based. In this article, the authors reflect upon information-based conflict in Africa. Areas of information conflict that are discussed include censorship, communications intercepts, the use of information and communications to instigate violence and uprisings, and the possibility of cyberwarfare. The article shows that the use of technology to conduct information conflict in Africa is prevalent, and that it is likely to increase.

    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.

  16. Anthropogenic CO2 emissions in Africa

    Full Text Available An understanding of the regional contributions and trends of anthropogenic carbon dioxide (CO2 emissions is critical to design mitigation strategies aimed at stabilizing atmospheric greenhouse gases. Here we report CO2 emissions from the combustion of fossil fuels and land use change in Africa for various time periods. Africa was responsible for an average of 500 TgC y−1 for the period 2000–2005. These emissions resulted from the combustion of fossil fuels (260 TgC y−1 and land use change (240 TgC y−1. Over this period, the African share of global emissions from land use change was 17%. For 2005, the last year reported in this study, African fossil fuel emissions were 285 TgC accounting for 3.7% of the global emissions. The 2000–2005 growth rate in African fossil fuel emissions was 3.2% y−1, very close to the global average. Fossil fuel emissions per capita in Africa are among the lowest in the world, at 0.32 tC y−1 compared to the global average of 1.2 tC y−1. The average amount of carbon (C emitted as CO2 to produce 1 US $ of Gross Domestic Product (GDP in Africa in 2005 was 187 gC/$, close to the world average of 199 gC/$. With the fastest population growth in the world and rising per capita GDP, Africa is likely to increase its share of global emissions over the coming decades although emissions from Africa will remain low compared to other continents.

  17. Narrative review of EHDI in South Africa

    2015-02-01

    Full Text Available Background: With 17 babies born with hearing loss every day in South Africa, there is a pressing need for systematic Early Hearing Detection and Intervention (EHDI services. Progress is being made in offering newborn hearing screening and studies have been conducted to document these processes within South Africa. However, due to the lack of a national and holistic overview of EHDI services to date, an accurate picture of the current status of EHDI within the South African context is required. Objective: To document and profile what has been published within the field of EHDI in South Africa over the last two decades (Jan 1995–Sept 2014 in order to gain a comprehensive overview of the current status and practice of screening and diagnosis in the field of paediatric hearing loss. Method: A narrative review of peer-reviewed articles related to EHDI in South Africa was conducted by searching the EBSCOHOST, SCOPUS and JSTOR databases for the period January 1995 to September 2014. Results: Results indicate that over the last two decades research and publications in the field of EHDI have increased considerably. These publications have revealed extensive knowledge related to paediatric hearing screening and intervention services in South Africa; however, this knowledge seems to be limited primarily to the provinces of Gauteng and the Western Cape. Furthermore, studies pertaining to diagnosis have revealed that, although much has been written on the scientific aspects on tools for diagnosis of hearing loss, there is a lack of comprehensive information on diagnostic protocols and procedures. Conclusion: Despite the clear progress being made in South Africa in the field of early hearing detection and intervention, there is a need for comprehensive studies on protocols and procedures in diagnosing paediatric hearing loss. Finally, the narrative review revealed a clear need to ensure that development and growth in the field of EHDI is a national priority

    2013-12-01

    Stem cells have received much attention globally due in part to the immense therapeutic potential they harbor. Unfortunately, malpractice and exploitation (financial and emotional) of vulnerable patients have also drawn attention to this field as a result of the detrimental consequences experienced by some individuals that have undergone unproven stem cell therapies. South Africa has had limited exposure to stem cells and their applications and, while any exploitation is detrimental to the field of stem cells, South Africa is particularly vulnerable in this regard. The current absence of adequate legislation and the inability to enforce existing legislation, coupled to the sea of misinformation available on the Internet could lead to an increase in illegitimate stem cell practices in South Africa. Circumstances are already precarious because of a lack of understanding of concepts involved in stem cell applications. What is more, credible and easily accessible information is not available to the public. This in turn cultivates fears born out of existing superstitions, cultural beliefs, rituals and practices. Certain cultural or religious concerns could potentially hinder the effective application of stem cell therapies in South Africa and novel ways of addressing these concerns are necessary. Understanding how scientific progress and its implementation will affect each individual and, consequently, the community, will be of cardinal importance to the success of the fields of stem cell therapy and regenerative medicine in South Africa. A failure to understand the ethical, cultural or moral ramifications when new scientific concepts are introduced could hinder the efficacy and speed of bringing discoveries to the patient. Neglecting proper procedure for establishing the field would lead to long delays in gaining public support in South Africa. Understanding the dangers of stem cell tourism - where vulnerable patients are subjected to unproven stem cell therapies that

    Full Text Available The emergence of more refined chronologies for climate change and archaeology in prehistoric Africa, and for the evolution of human mitochondrial DNA (mtDNA, now make it feasible to test more sophisticated models of early modern human dispersals suggested by mtDNA distributions. Here we have generated 42 novel whole-mtDNA genomes belonging to haplogroup L0, the most divergent clade in the maternal line of descent, and analysed them alongside the growing database of African lineages belonging to L0's sister clade, L1'6. We propose that the last common ancestor of modern human mtDNAs (carried by "mitochondrial Eve" possibly arose in central Africa ~180 ka, at a time of low population size. By ~130 ka two distinct groups of anatomically modern humans co-existed in Africa: broadly, the ancestors of many modern-day Khoe and San populations in the south and a second central/eastern African group that includes the ancestors of most extant worldwide populations. Early modern human dispersals correlate with climate changes, particularly the tropical African "megadroughts" of MIS 5 (marine isotope stage 5, 135-75 ka which paradoxically may have facilitated expansions in central and eastern Africa, ultimately triggering the dispersal out of Africa of people carrying haplogroup L3 ~60 ka. Two south to east migrations are discernible within haplogroup LO. One, between 120 and 75 ka, represents the first unambiguous long-range modern human dispersal detected by mtDNA and might have allowed the dispersal of several markers of modernity. A second one, within the last 20 ka signalled by L0d, may have been responsible for the spread of southern click-consonant languages to eastern Africa, contrary to the view that these eastern examples constitute relicts of an ancient, much wider distribution.

    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.

    variables which are not available at a global scale and thus not incorporated in this study as well as its coarse resolution. An application of the models using climate hindcasts and projections ranging from 1980 to 2060 resulted in a strong decrease of burned area of ca. 20–25%. Since wildfires are an integral part of land use practices in Africa, their occurrence is an indicator of areas favourable for food production. In absence of other compensating land use changes, their projected decrease can hence be interpreted as a indicator for future loss of such areas.

  4. Tele-education in South Africa

    2014-11-01

    Full Text Available Telemedicine includes the use of information and communication technology for education in the health sector, tele-education. Sub-Saharan Africa has 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 programmes. 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 programmes with respect to current thinking on eHealth project implementation.Method: 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.Results: 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. Despite initial attempts by the National Department of Health 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 hours of videoconferenced education offered per year. The service has expanded to offer videoconferenced education into Africa using different ways of delivering tele-education.Conclusions: 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

  5. Elimination of onchocerciasis from Africa: possible?

    2012-01-01

    Human onchocerciasis, a parasitic disease found in 28 African countries, six Latin American countries and Yemen, causes blindness and severe dermatological problems. In 1987, efforts to control this infection shifted from vector approaches to include the mass distribution of ivermectin - a drug donated by Merck & Co. for disease control in Africa and for disease elimination in the Americas. Currently, almost 25 years later, with the Americas being highly successful and now approaching elimination, new evidence points towards the possibility of successful elimination in Africa. We suggest several major changes in the programmatic approach that through focused goal-directed effort could achieve global elimination of onchocerciasis by 2025.

    Lassa fever, a zoonotic viral infection, is endemic in West Africa. The disease causes annual wide spread morbidity and mortality in Africa, and can be imported by travelers. Possible importation of Lassa fever and the potential for the use of Lassa virus as an agent of bioterrorism mandate clinicians in Israel and other countries to be vigilant and familiar with the basic characteristics of this disease. The article reviews the basis of this infection and the clinical management of patients with Lassa fever. Special emphasis is given to antiviral treatment and infection control.

    2008-03-01

    It is a decade since the exposure of Project Coast, apartheid South Africa's covert chemical and biological warfare program. In that time, attention has been focused on several aspects of the program, particularly the production of narcotics and poisons for use against anti-apartheid activists and the proliferation of both chemical and biological weapons. The eugenic dimension of Project Coast has, by contrast, received scant attention. It is time to revisit the testimony that brought the suggestion of eugenic motives to light, reflect on some of the Truth and Reconciliation Commission's findings and search for lessons that can be taken from this troubled chapter in South Africa's history.

    South Africa is now emerging from the period of Apartheid. Elections will be held soon, but the economic damage caused by Apartheid has to be rectified. Partly this will be through an industrial strategy, and the minerals industry will play its part. The coal mining industry provides a large proportion of South Africa's exports and 90% of electricity. It is also the basis of a synfuels industry. The coal industry will continue to be an important source of exports, either directly, or as the provider of power to energy intensive industries such as aluminium production.

    2014-05-01

    Full Text Available A lot of issues have been raised to argue that equivalent drugs may not work as well or at least the same as what the drug industry likes to call innovator products. Many doubts and biases are also reported in connection with the use of generic drugs. Doctors are mostly concerned about their efficacy, their tolerability, the quality and amount of active ingredients, their formulation or excipients, their packaging, their pharmaceutical form and their palatability. We describe the differences between prescribability (equivalence when prescribing a drug to a patient for the first time and switchability (interchangeability of drugs for a patient already in treatment considering the notions of average bioequivalence, population bioequivalence and individual bioequivalence as well as the usefulness of the U.S. Orange Book in the assessment of bioequivalence. Other key issues deserve attention, such as: duplicate applications for medicinal products, different salt forms, formulations used in the development of each medicinal product and excipients, product quality. Clinicians in collaboration with pharmacists and research pharmacologists have to find solutions for unanswered questions and unsolved doubts, by developing targeted studies, communication tools and shared guidelines.

  16. Narrating survival and change in Guatemala and South Africa: the politics of representation and a liberatory community psychology.

    Science.gov (United States)

    Lykes, M Brinton; Blanche, Martin Terre; Hamber, Brandon

    2003-03-01

    Peace accords and international interventions have contributed to the suspension of armed conflict and the censuring of repressive regimes in many parts of the world. Some governments and their opposition parties have agreed to the establishment of commissions or other bodies designed to create historical records of the violations of human rights and foster conditions that facilitate reparatory and reconciliatory processes. This paper explores selected roles that community psychologists have played in this process of remembering the past and constructing new identities towards creating a more just future. With reference to two community groups (in Guatemala and South Africa) we show how efforts to "speak out" about one's own experiences of political and military repression involve complex representational politics that go beyond the simple binary opposition of silencing versus giving voice. The Guatemalan group consisted of Mayan Ixil women who, together with the first author, used participatory action research and the PhotoVoice technique to produce a book about their past and present struggles. The South African group, working within the ambit of the Truth and Reconciliation Commission and in collaboration with the third author and others, explored ways of speaking about their roles in apartheid and post-apartheid society. Although both these initiatives can be seen as moments in on-going struggles to overcome externally-imposed repressive practices that censor the voices of marginalized communities, they also serve to dispel overly romanticized notions of "univocal" communities now liberated to express themselves in an unmediated and unequivocal fashion. The paper discusses how each group of women instead entered into subtly nuanced relationships with community psychologists involving a continual interplay between the authenticity of their self-representational accounts and the requirements of the discursive technologies into which they were being inducted and

    1986-08-01

    Not only is Africa experiencing severe food production and nutrition problems, but environmental conditions, on which agricultural production ultimately depends, are deteriorating. A meeting of the African Ministers of Environment was held in Cairo last December, and an African solution to an African problem was put forth. The proposed program is examined in this paper. The usable extent of the pastoral area in the arid and semi-arid regions of Africa nas been reduced by 25% since 1968. At present only about 35% of the former area of slightly productive savannah is left. Africa's rich fishing grounds are being overfished and coastal regions are threatened by pollution. Africa's problems are linked with very high rates of population growth, rapid rates of urbanization, inappropriate development policies that have neglected the agricultural sector, and nonavailability of skilled manpower. The Cairo Program of African Cooperation included the following proposals: 8 continent-wide networks of institutions are to be established or strenghened in the fields of climatology, soils and fertilizers, water resources, energy, genetic resources, environmental monitoring, science and technology, and education and training; all available African skills and experience are to be applied to seek economically feasible, environmentally sound and socially acceptable solutions in certain regions; subregional cooperation is to be strenghened in terms of implementation of priority activities; 4 committees were established in areas of priority concerns; and a formula to provide US$32.5 million to finance the follow-up activities was approved.

    Bloland, P B; Kazembe, P N; Watkins, W M; Doumbo, O K; Nwanyanwu, O C; Ruebush, T K

    1997-11-29

    Glaxo Wellcome announced in November 1996 its intent to donate up to 1 million treatment courses per year of its new antimalarial drug, Malarone, to countries in Africa, Southeast Asia, and South America, where malaria is endemic. Because the effectiveness of the small number of available antimalarial drugs is threatened by the emergence of drug resistance, the advantages of introduction of this new drug to a given area should be given careful consideration. Chloroquine, for example, is nearing the end of its effectiveness as a first-line drug for the treatment of uncomplicated falciparum malaria in many areas of East and Central Africa. The lifespan of its replacement, sulfadoxine-pyrimethamine, is likely to be even shorter given its long half-life and the ease with which resistance-conferring mutations occur. In Southeast Asia and the Amazon basin of South America, where multidrug-resistant Plasmodium falciparum malaria is a serious problem, the advantages of Malarone introduction clearly outweigh any disadvantages. In sub-Saharan Africa, the premature distribution and increasing use of artemisinins may jeopardize their long-term effectiveness, however. Another factor complicating decisions to introduce Malarone is its required 3-day course of treatment, necessitating hospitalization if compliance is to be ensured. The donation project gives patients in developing countries access to an expensive drug that would otherwise be unavailable. Time must be taken, however, to fully debate the project's pros and cons, resolve inherent logistic problems, and establish guidelines for Malarone use in sub-Saharan Africa.

  17. Eastern Africa: mapping the politics of AIDS.

    Science.gov (United States)

    Hyden, G; Lanegran, K

    1991-01-01

    The political constraints slowing the battle against AIDS in Africa are getting AIDS on the public agenda, integrating the international community into the AIDS policy-making agenda and cultural barriers in national AIDS strategies. Policy making in most Africa is bureaucratic rather than democratic, so whether AIDS is a government priority depends largely on perception of AIDS risk by the leaders. In Zambia and Uganda, AIDS is a concern because it affects the ethnic group or family in power, while in Tanzania and Kenya, AIDS is associated with minority or "high risk" groups. The domination of AIDS agenda setting within nations in Africa by international donors and non-governmental organizations is a problem, made more severely severed by sensitivity of Africans who perceive research as a foreign effort to prove that AIDS originated there. Foreign domination is also detrimental because it prevents localities from becoming committed to AIDS interventions. Cultural barriers against effective interventions are similar to those in Western countries: AIDS is seen as a disease of shame affecting immoral people. In addition, the prevalent concept of fatalism defeats the Western insistence on intervention and strategies. Furthermore, women who are largely dependent on men cannot insist on preventive behavior, not do they have organizations in place to protect their rights. Finally, the concepts of behavioralism, and learning new behaviors for person-centered reasons, are foreign to much of Africa.

    2016-04-01

    We present the Seismotectonic Map of Africa based on a geological, geophysical and geodetic database including the instrumental seismicity and re-appraisal of large historical events, and harmonization and homogenization of earthquake parameters in catalogues. Although the seismotectonic framework of the African continent is a difficult task, several previous and ongoing projects provide a wealth of data and outstanding results. The database of large and moderate earthquakes in different geological domains includes the coseismic and Quaternary faulting that reveals the complex nature of the active tectonics in Africa. The map benefits from previous works on local and regional seismotectonic maps that needed to be integrated with the lithospheric and upper mantle structures, seismic anisotropy tomography and gravity anomaly, into a continental framework. The synthesis of earthquake and volcanic studies obtained from the analysis of late Quaternary faulting and geodetic data will serve as a basis for hazard calculations and the reduction of seismic risks. The map will be useful for the seismic hazard assessment and earthquake risk mitigation for significant infrastructures and their socio-economic implications in Africa. The constant population increase and infrastructure growth in the continent that exacerbate the earthquake risk justify the necessity for a continuous updating of this map. The database and related map are prepared in the framework of the IGC Project-601 "Seismotectonics and Seismic Hazards in Africa" of UNESCO-IUGS, funded by the Swedish International Development Agency and UNESCO-Nairobi for a period of 4 years (2011 - 2014, now extended to 2016).

    Social inequalities in health are increasingly in the news in Africa. While appeals, international declarations and new strategies for health in Africa have succeeded one another over the years, we must admit that the health inequalities are increasing. It is perhaps time to take health out of its compartment and understand that it is one of the components of overall development and that we cannot act effectively against these health inequalities unless we also act on the pressing need to see all States (in the North and South) finally meet their financial commitments, demand of African leaders that they provide good government and fight against corruption, the leaders of African good government and a fight against corruption, and finally ensure that the strategies proposed in Africa focus on the health priorities of each country. If we mention the Scandinavian example, we must admit that the Nordic countries have demonstrated their capacity to obtain excellent results in health, to narrow social inequalities, and provide public transparency and aid to development. They constitute today an excellent example for most Western countries and for African countries - and also for African and western civil societies, which can be inspired by the concrete measures of transparency and strong public activity, which promote improvement in the overall statistics of their societies, in particular, in health. Accordingly we propose a new approach that looks at health statistics in the light of inequalities (especially via the Gini coefficient) and public transparency (especially via the benchmarks of perceived corruption). A New Deal for health in Africa is needed, and all the organization involved should be asked to act together for a holistic public health vision that will benefit the populations of Africa. Health cannot be separated from a political, ethical and equitable vision of society.

    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.

  17. Marketing of irradiated commodities in South Africa

    Science.gov (United States)

    Du Plessis, TA; Stevens, RCB

    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.

  18. Cardiomyopathy in Africa: heredity versus environment.

    Science.gov (United States)

    Mayosi, Bongani M; Somers, Krishna

    2007-01-01

    Unlike other parts of the world in which cardiomyopathy is rare, heart muscle disease is endemic in Africa. The major forms of cardiomyopathy in Africa are dilated cardiomyopathy (DCM) and endomyocardial fibrosis (EMF). Whereas DCM is a major cause of heart failure throughout the continent, EMF is restricted to the tropical regions of East, Central, and West Africa. Although epidemiological studies are lacking, hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy seem to have characteristics similar to those of other populations elsewhere in the world. Recent advances in the genetic analysis of DCM in other parts of the world indicate that it is a genetically heterogeneous disorder in which some cases have a Mendelian cause and others have a non-genetic or multifactorial cause. This heterogeneous pattern of inheritance has been confirmed in small studies that have been conducted so far in Africa. The advent of human immunodeficiency virus infection and its association with cardiomyopathy has emphasised the role of inflammatory agents in the pathogenesis of DCM. By contrast with DCM in which some cases have major genetic contributions, there is scanty evidence for the role of genetic factors in the aetiology of EMF. Although the pathogenesis of EMF is not fully understood, it appears that the conditioning factor may be geography (in its widest sense, to include climate and socio-economic status), the triggering factor may be an as yet unidentified infective agent, and the perpetuating factor may be eosinophilia. There is a need for renewed effort to identify genetic and non-genetic factors in EMF and other forms of heart muscle disease that are prevalent on the continent of Africa.

  19. [The role of female veterinarians in Africa].

    Science.gov (United States)

    Balogh, K K

    2000-01-01

    While the number of female veterinary students has reached figures as over 80% in the Netherlands and other European countries, the number of female veterinary students in Africa is also changing but still at a slower pace. Still nowadays, according to UNICEF, two-thirds of primary school age children, denied their right to basic education, are girls. In addition, especially in rural areas in Africa, there are only few secondary schools, so that children, either have to travel over large distances on a daily basis or have to live away from their families. As girls, already from an early age play an important role in the daily household routine, they are often not allowed to leave for schooling. There used to be less than 10 veterinary faculties in Africa during the first half of the 20th century. These faculties were located in South Africa, Sudan, Egypt and Nigeria. For many years, African veterinarians were also trained in western countries (UK, France, USA) or in former communist countries (Russia, Ukraine, Romania, Hungary Eastern Germany, Cuba) depending on the existence of historic or political links. A long stay abroad made it more difficult for female students, especially for those with children. Still nowadays, female veterinarians in Africa are mostly working for the veterinary departments mainly in the urban areas. Another area where many female veterinarians can be found are governmental diagnostic and research laboratories as well as training institutions such as veterinary faculties or agricultural colleges. Generally the salaries at these institutions are very low and therefore their male colleagues have gradually shifted to work in the private sector with more competitive salaries (private clinics, sector pharmaceutical companies, development projects, (agricultural) banks, etc). As still in most societies, women tend to follow their husbands, most female veterinarians are bound to find employment where their husbands are based. In addition, as most

MÉTODO: participaram desta pesquisa 24 indivíduos, sendo 12 com gagueira (GE1 e GE2 e 12 sem gagueira (GC. Foram coletadas amostras que teve como base um corpus de 10 frases chave que foram produzidas nas formas neutra, de dúvida e de certeza, totalizando 840 enunciados. A análise acústica foi realizada por meio do programa Praat e os seguintes parâmetros foram analisados: tempos e taxas de elocução e articulação, ocorrência e duração de pausas e disfluências, duração das vogais tônica e pré-tônica e ocorrência da vogal pós-tônica. A análise estatística foi realizada por meio dos testes Kruskall Wallis e qui-quadrado, com índice de significância de 95%. RESULTADOS: a expressão da dúvida apresenta taxa de articulação mais baixa no grupo controle, seguida da forma neutra e de certeza, com diferenças estatisticamente significantes. Ainda no grupo controle, foi observado presença de pausas e disfluências somente na expressão de dúvida. No grupo experimental, a maior diferença encontrada foi na duração da vogal da sílaba tônica. CONCLUSÃO: de uma forma geral, o GC variou mais sua organização temporal a fim de expressar as atitudes. No entanto, é possível observar também uma tendência semelhante no grupo de pessoas com gagueira. Quanto à velocidade de fala, ao retirar as pausas e as disfluências, vemos que tanto GE1 quanto GE2 diferenciam a certeza, articulando cada sílaba de forma mais rápida.PURPOSE: to examine the role of speech temporal organization on the expression as for the attitudes of certainty and doubt in the group of adults who stutter, comparing such analysis with a group of speech-fluent adults.

  1. Discrepancies in data reporting for rabies, Africa.

    Science.gov (United States)

    Nel, Louis H

    2013-04-01

    Human rabies is an ancient disease but in modern times has primarily been associated with dog rabies-endemic countries of Asia and Africa. From an African perspective, the inevitable and tragic consequences of rabies require serious reflection of the factors that continue to drive its neglect. Established as a major disease only after multiple introductions during the colonial era, rabies continues to spread into new reservoirs and territories in Africa. However, analysis of reported data identified major discrepancies that are indicators of poor surveillance, reporting, and cooperation among national, international, and global authorities. Ultimately, the absence of reliable and sustained data compromises the priority given to the control of rabies. Appropriate actions and changes, in accordance to the One Health philosophy and including aspects such as synchronized, shared, and unified global rabies data reporting, will not only be necessary, but also should be feasible.

  2. The foreign debt problem of Africa

    Directory of Open Access Journals (Sweden)

    P. Decoodt

    1987-01-01

    Full Text Available The foreign debt problem of Sub-Saharan Africa (SSA, although an important obstacle against economic growth, is not the region's major economic problem. The creditors are less concerned about the relative small debt figures of SSA because of the lower risks for the equilibrium of the financial system. But from the debtors' viewpoint, the debt situation is possibly even more critical in low-income Africa than in the richer major debtor countries. SSA has a predominance of official creditors with the best obtainable credit terms. Notwithstanding these good terms, SSA is so poor that it has difficulties with fulfilling its debt service. There is no single solution for the African debt crisis. Anyway the official creditors have to adopt a more flexible attitude. The debtor countries have also to accept their own responsibility in the solutions of the problem.

  3. Biosedimentology of Quaternary stromatolites in intertropical Africa

    Science.gov (United States)

    Casanova, J.

    Mineralizations of microbial origin constitute a non-negligeable part of Quaternary limestones in intertropical Africa. Stromatolites have colonized a wide range of environments corresponding to different hydroclimatic situations: travertines in fluviatile environments, oncolites in flood plains, encrustations in sebkha areas and shorelines of deep, fresh water lakes. The developed morphologies represent a complete catalogue of the microbial carbonated mineralizations: oncolites, chemneys, pool-rim dams, biocherms, planar or cylindrical encrustations. The building organisms may be either pure bacterial colonies (hydrothermal and lacustrine environments), cyanophyte associations (fluviatile and lacustrine environments) or complex microbial biocoenoses. Stromatolites have recorded the hydrologic, climatic and sedimentologic evolution of the continental environment in intertropical Africa for the past 240 000 years.

  4. The metabolic syndrome in Africa: Current trends.

    Science.gov (United States)

    Okafor, Christian I

    2012-01-01

    Metabolic syndrome is a clustering of several cardiovascular risk factors. Contrary to earlier thoughts, metabolic syndrome is no longer rare in Africa. The prevalence is increasing, and it tends to increase with age. This increase in the prevalence of metabolic syndrome in the continent is thought to be due to departure from traditional African to western lifestyles. In Africa, it is not limited to adults but is also becoming common among the young ones. Obesity and dyslipidemia seem to be the most common occurring components. While obesity appears more common in females, hypertension tends to be more predominant in males. Insulin resistance has remained the key underlying pathophysiology. Though pharmacologic agents are available to treat the different components of the syndrome, prevention is still possible by reverting back to the traditional African way of life.

The HIV and AIDS Treatment Action Campaign, an advocacy group, had lobbied New York-based Pfizer for a year to reduce the drug's price. The donation offered hope among activists that other pharmaceutical companies would follow suit and offer HIV- and AIDS-related drugs at a discount or for free. After the announcement of the donation, the group is now lobbying Glaxo Wellcome, maker of Zidovudine. The group is asking to make the drug available for free to reduce the risk of vertical transmission. Glaxo Wellcome, however, has no plans of offering Zidovudine for free, although the drug was offered 75% cheaper in developing nations.

  6. Solvent Extraction Developments in Southern Africa

    The largest solvent-extraction plant in the world at the time, the Nchanga Copper Operation, was in Zambia. The first commercial process using solvent extraction for the refining of the platinum-group metals was in South Africa. More recently, the Southern African region has seen the implementation of solvent extraction for other base metals, precious metals, and specialty metals. These include the world firsts of primary production of zinc at Skorpion Zinc in Namibia and the large-scale refining of gold by Harmony Gold in South Africa. Several other flowsheets that use solvent-extraction technology are currently under commissioning, development, or feasibility study for implementation in this part of the world, including those for the recovery of copper, cobalt, nickel, tantalum, and niobium.

  9. Asia in the New Distribution of Africa

    Directory of Open Access Journals (Sweden)

    Luis María Mora

    2000-01-01

    Full Text Available The relations between sub-Saharan Africa and east Asia have developed at a considerable rate over the recent decades. The economic figures and political interests are testimony to a new distribution of influences on the Dark Continent, insomuch as the powerful nations along the Asiatic shore are now competing with both the former colonial mother counties and the United States. Indeed, if the economic weight of Africa’s market is weak world-wide, this does not make it unattractive from a strategic point of view for those Asiatic countries looking for international prestige or resources for their growing economies. This rapprochement, motivated by political reasons also, seems exemplified by the growing presence of major economies like Japan and China - as well as those aspirations of the middle-sized powers like South Korea and Malaysia - in the international issues concerning sub-Saharan Africa.

    Full Text Available We have examined the temperature time series across several locations in Africa. In particular, we focus on three countries, South Africa, Kenya, and Côte d’Ivoire, examining the monthly averaged temperatures from three weather stations at different locations in each country. We examine the presence of deterministic trends in the series in order to check if the hypothesis of warming trends for these countries holds; however, instead of using conventional approaches based on stationary I(0 errors, we allow for fractional integration, which seems to be a more plausible approach in this context. Our results indicate that temperatures have only significantly increased during the last 30 years for the case of Kenya.

  11. Aims of education in South Africa

    Science.gov (United States)

    Morrow, Walter Eugene

    1990-06-01

    The first part of this paper gives a historical account of the aims of education under Apartheid, and discusses the ideological success of Apartheid education. The second part argues that a significant discussion — that is one which could have some purchase on schooling policy and educational practice — of aims of education in South Africa is not possible at present because the historical preconditions for such a discussion are not satisfied. It is argued that Apartheid has generated a political perspective which is unsympathetic to a discussion of aims of education; that the dominance of a social engineering model of schooling distorts a discussion of aims of education; and that a shared moral discourse, which is a necessary condition for a significant discussion of aims of education, does not yet exist in South Africa.

  12. AIDS in Africa: misinformation and disinformation.

    Science.gov (United States)

    Konotey-Ahulu, F I

    1987-07-25

    Relying on his tour of 16 sub-Saharan countries, the author judges the extent of acquired immunodeficiency syndrome (AIDS) in Africa on a scale from grade I (not much of a problem) to grade V (a catastrophe). In his assessment, AIDS is a problem (grade II) in only 5, possibly 6, countries where it has occurred. In no country is the AIDS problem consistently grade III (a great problem), nor ever grade IV (an extremely great problem), and in none can it be called a catastrophe (grade V). In Kenya, for instance, contrary to widespread rumors, the author rates AIDS in 1987 as grade I. Journalistic hyperbole has proved very expensive in that Africans overseas have experienced racial abuse and tourism has unjustly suffered. Tension seems to have developed between white doctors working in Africa, with externally funded research in danger of being halted in several countries.

    Science.gov (United States)

    Paarlberg, Robert

    2010-11-30

    There is a scientific consensus, even in Europe, that the GMO foods and crops currently on the market have brought no documented new risks either to human health or to the environment. Europe has decided to stifle the use of this new technology, not because of the presence of risks, but because of the absence so far of direct benefits to most Europeans. Farmers in Europe are few in number, and they are highly productive even without GMOs. In Africa, by contrast, 60% of all citizens are still farmers and they are not yet highly productive. For Africa, the choice to stifle new technology with European-style regulations carries a much higher cost.

  7. Malaria vaccine offers hope. International / Africa.

    Science.gov (United States)

    1995-04-01

    The World Health Organization (WHO) may soon sign an agreement with the Colombian government to build a plant in Colombia for the mass production of the malaria vaccine SPf66. SPf66 consists of a combination of synthetic peptides. It will eventually be available in Africa, where 90% of all recorded malaria cases occur each year. 1 million of the 1.5-3 million malaria-related deaths each year also occur in Africa. Many of these deaths take place in children. The indirect costs of malaria in Africa is expected to increase from $800 million to $1.8 billion between 1987 and the end of 1995. Based on findings from the various clinical trials in Colombia, Thailand, The Gambia, and Tanzania, WHO's director of Training in Tropical Diseases (TDR) claims that, if SPf66 can reduce the malaria incidence rate by 50% and thereby also the malaria-related death rate, the lives of 500,000 children in Africa would be spared. TDR will meet in mid-1996 to sort through all the SPf66 findings and then develop a policy for further development or production and use of SPf66. The price of each SPf66 vaccination should be around $5, comparable with the higher range of costs of other vaccines provided by WHO's Expanded Program of Immunization and UNICEF. At the 1992 WHO summit in Amsterdam, the president of the Congo called for the international community to join forces to eliminate malaria. When it was first tested on humans, in Colombia, the protection rate of SPf66 ranged from 22% to 77%, with the best results among the young and the very old. It has not caused any harmful side effects.

  11. Culture and genetic screening in Africa.

    Science.gov (United States)

    Jegede, Ayodele S

    2009-12-01

    Africa is a continent in transition amidst a revival of cultural practices. Over previous years the continent was robbed of the benefits of medical advances by unfounded cultural practices surrounding its cultural heritage. In a fast moving field like genetic screening, discussions of social and policy aspects frequently need to take place at an early stage to avoid the dilemma encountered by Western medicine. This paper, examines the potential challenges to genetic screening in Africa. It discusses how cultural practices may affect genetic screening. It views genomics science as a culture which is trying to diffuse into another one. It argues that understanding the existing culture will help the diffusion process. The paper emphasizes the importance of genetic screening for Africa, by assessing the current level of burden of diseases in the continent and shows its role in reducing disease prevalence. The paper identifies and discusses the cultural challenges that are likely to confront genetic screening on the continent, such as the worldview, rituals and taboos, polygyny, culture of son preference and so on. It also discusses cultural practices that may promote the science such as inheritance practices, spouse selection practices and naming patterns. Factors driving the cultural challenges are identified and discussed, such as socialization process, patriarchy, gender, belief system and so on. Finally, the paper discusses the way forward and highlights the ethical considerations of doing genetic screening on the continent. However, the paper also recognizes that African culture is not monolithic and therefore makes a case for exceptions.

  12. Democracy and Elections in Africa: Critical Analysis

    Directory of Open Access Journals (Sweden)

    Wondwosen Teshome

    2008-07-01

    Full Text Available The aim of this article is to assess the democratization process in Africa in general and the multi-party elections in particular. The decolonization process in Africa (1960s and 1970s, which was known as the “first liberation” completed by the emergence of many, new independent African countries. In most of the newly liberated countries the political parties that led the anti-colonial struggle established one-party domination after independence. The rapid democratization process (“second liberation” in Africa began in the first half of the 1990s, particularly with Benin’s multiparty election in 1991. In this period, multi-party elections had taken place in most of African countries. These transitions led to “limited” democracies, characterized by a lack of liberal freedoms, low levels of popular involvement (except at election times, narrow range of civil liberties and the concentration of political power in the hands of small elite groups. Holding an election is a milestone, but it is not the key to Africa’s democratic legitimacy. Many elections in the African region have failed to meet the internationally accepted standards for free and fair elections. Though Africa’s record on free and fair elections is mixed, at present, most of Africans have embraced elections as indispensable mechanism for determining their future course.

  13. Governance and poverty reduction in Africa.

    Science.gov (United States)

    Hyden, Goran

    2007-10-23

    A careful review of the literature in political science and neighboring social science disciplines shows that prevailing assumptions in the international development policy community about improved governance as a principal mechanism to reduce poverty in Africa rests more on faith than science. Conventional policy models for tackling poverty fail to take into account the peculiar socioeconomic and political conditions in Africa, where the vast majority of those living on one dollar a day or less are only marginally captured by market and state institutions and instead rely on solving their problems "outside the system." Poverty reduction through formal institutions therefore becomes ineffective. Although political science and other neighboring social science disciplines offer insights into these peculiarities, these contributions have been largely ignored to date. One reason is that economists continue to dominate the international development policy agenda. Another is that political scientists have typically looked at how economic variables shape political ones, rather than the other way around, as implied in the current governance agenda. Governance remains an undertheorized area of research held back by two chasms, one between economists and other social scientists and another between the scientific and the policy communities, to the detriment of gaining a better understanding of how it may help reduce poverty in Africa.

  14. Energy Security and Sub-Saharan Africa

    Directory of Open Access Journals (Sweden)

    Emily Meierding

    2013-02-01

    Full Text Available Published by Palgrave MacmillanOver the last decade the topic of energy security has reappeared on global policy agendas. Most analyses of international energy geopolitics examine the interests and behaviour of powerful energy-importing countries like the US and China. This chapter begins by examining foreign powers’ expanded exploitation of oil and uranium resources in Sub-Saharan Africa. It goes on to examine how energy importers’ efforts to enhance their energy security through Africa are impacting energy security within Africa. It assesses Sub-Saharan states’ attempts to increase consumption of local oil and uranium reserves. Observing the constraints on these efforts, it then outlines some alternative strategies that have been employed to enhance African energy security. It concludes that, while local community-based development projects have improved the well-being of many households, they are not a sufficient guarantor of energy security. Inadequate petroleum access, in particular, remains a development challenge. Foreign powers’ efforts to increase their oil security are undermining the energy security of Sub-Saharan African citizens.

  15. Conservation strategies for Africa's large mammals.

    Science.gov (United States)

    Hanks, J

    2001-01-01

    Africa's large mammals are conserved for their aesthetic, scientific and economic values. Many of these species face a gloomy future precipitated by a combination of factors directly and indirectly influenced by the activities of man, including habitat loss, overexploitation, poor management of designated protected areas, and the vulnerability of small isolated populations. Africa's designated protected areas and biodiversity hotspots are also under threat, highlighting the importance of embracing community participation to address accelerating poverty and malnutrition. Innovative strategies are required for the conservation of Africa's mammals, such as the integration of a wide range of species in the production landscape, including the farming community. Transfrontier conservation areas (TFCAs) have been established with the combined objectives of conserving biodiversity, creating new jobs in the tourism and wildlife industry, and promoting a culture of peace. These areas extend far beyond traditional national parks, providing opportunities for integrating large mammals into sustainable land-use practices, at the same time as addressing some of the continent's more pressing socioeconomic needs. Research on African mammals will inevitably have to change direction to accommodate the growing threats and changed circumstances. Priorities will include the identification of corridors associated with TFCA establishment, the determination of the economic value of certain species in consumptive use programmes, research on contraception as a management option in restricted areas, and further work on the indirect use value of species. There will also be worthwhile opportunities to be pursued with ex situ conservation programmes, but these need to be focussed more efficiently.

  16. Sub-Saharan Africa's media and neocolonialism.

    Science.gov (United States)

    Domatob, J K

    1988-01-01

    Given the heavy Western metropolitan bias of the media in sub-Saharan Africa, the ideology of neocolonialism continues to exert a dominant influence on economic, social, political, and cultural life. This neocolonial influence is further reinforced by advertising that champions a consumerist culture centered around Western goods. The capital of multinational firms plays a crucial role in the strategy of media imperialism. The dramatic growth of monopolies and the creation of military-industrial-information conglomerates in the 1970s and 1980s have been reflected in the international exchange of information and the interlinkage of mass communication systems in sub-Saharan Africa. Another media strategy that reinforces neocolonialism is the use of satellite communication. If cultural autonomy is defined as sub-Saharan Africa's capacity to decide on the allocation of its environmental resources, then cultural synchronization is a massive threat to that autonomy. Few African nations have the resources or expertise necessary to design, establish, or maintain communication systems that could accurately reflect their own culture. Nonetheless, there are some policy options. Personnel can be trained to respect African values and to recognize the dangers of neocolonial domination. The production of indigenous programs could reduce the media's foreign content. The incorporation of traditional drama and dance in the media could enhance this process. Above all, a high degree of planning is necessary if sub-Saharan African states intend to tackle the media and its domination by neocolonialist ideology.

  17. The genus Capsicum (Solanaceae in Africa

    Directory of Open Access Journals (Sweden)

    W. H. Eshbaugh

    1983-12-01

    Full Text Available The genus Capsicum (Solanaceae includes approximately 20 wild species and 4-5 domesticated taxa commonly referred to as ‘chilies’ or ‘peppers’. The pre-Colombian distribution of the genus was New World. The evolutionary history of the genus is now envisaged as including three distinct lines leading to the domesticated taxa. The route of Capsicum to the Old World is thought to have followed three different courses. First, explorers introduced it to Europe with secondary introduction into Africa via further exploratory expeditions; second, botanical gardens played a major role in introduction; and third, introduction followed the slave trade routes. Today, pepper production in Africa is of two types, vegetable and spice. Statistical profiles on production are difficult to interpret, but the data available indicate that Nigeria, Egypt, Tunisia and Ghana are the leading producers. Production is mainly a local phenomenon and large acreage is seldom devoted to the growing of peppers. The primary peppers in Africa are C.  annuum and C.  frutescens.

    This paper presents the effects of climate, topography, and natural ecology on public health, nutrition, demographics, technological diffusion, international trade and other determinants of economic development in Africa. The goal of this paper is to emphasize the need for intensified research on the issues at the intersection of ecology and human society. Geography was given emphasis because of three reasons: the minimal gain from another recitation of the damage caused by statism, protectionism and corruption to African economic performance; negligence of the role of natural forces in shaping economic performance; and tailoring of policies to geographical realities. The paper also discusses the general problems of tropical development and the focus of Africa's problems in worldwide tropical perspectives; demographic trends in Africa; use of standard cross-country growth equations with demographic and geographic variables, to account for the relative roles of geography; and the future growth strategies and the need for urban-based export growth in manufacturing and services. Lastly, the authors provide a summary of conclusions and discuss the agenda for future research.

  20. Education and Indigenous Knowledge in Africa: Traditional Bonesetting and Orthopaedic Medicine in West Africa

    Science.gov (United States)

    Ezeanya, Chika A.

    The underlying philosophy of education in contemporary Africa has been established to be alien, and detached from the indigenous knowledge of the people. Modern day formal education in sub-Saharan Africa came about, for the most part, as a result of missionary activities and colonial efforts of Europe. The education bequeathed to Africa was, therefore, fundamentally European in paradigm and lacking in authenticity. The end of colonialism across sub-Saharan Africa did not herald any tangible transformation in the curriculum of study. Education in Africa is still dependent on foreign input for sustainability, thereby stifling research, creativity and innovation. Sustainable development is founded on indigenous knowledge. When such grassroots knowledge assumes the foundation of learning, home-grown development is easily fostered in all sectors of a national economy. In the field of medicine, indigenous knowledge of healing has been considered unscientific by western biomedical practitioners. Since the days of the missionaries, many Africans have considered indigenous medicine to be fetish; the Christian converts would not be associated with its practice and patronage. However, traditional bonesetting has been proven to be highly efficacious with little supernatural content, it continues to attract huge patronage from Africans, cutting across social and religious boundaries. This study attempts an exploration of the disconnect between indigenous knowledge, practices and learning, on the one hand, and formal education in Africa, on the other. With a focus on traditional bonesetting, the study seeks to determine why that branch of indigenous medicine attracts huge patronage, but is granted very little recognition by modern orthopaedic medical education.

    2006-12-01

    Full Text Available Purpose: The aim of this paper is to assess and provide an overview of the magnitude of current agricultural trade patterns between South Africa and the five leading regional economic communities (REC's in Africa. This paper also seeks to examine some of the constraints limiting greater intra-African agricultural trade. This is done in order to better understand the role South Africa currently plays and could potentially play in promoting intra-Africa trade. Design/Methodology/Approach: Trade flows between South Africa and the leading REC's are outlined and explained. Trade data and tariff data is sourced from available databases. Non-tariff barriers and other impediments to greater intra-African trade are examined with reference to available literature and discussions the authors have had with trade experts and policy makers.Findings: South Africa is the most active country in intra-Africa agricultural trade. However, it is a relationship defined predominantly on exports to Africa with a low level of imports. South Africa exports a diverse range of value added products whilst imports remain concentrated in commodities. Significant imbalances in agricultural trade between South Africa and the respective REC's continue to persist. Regional trade arrangements have fostered greater trade but significant obstacles to greater trade remain.Implications: African countries that do not invest in infrastructure and create a trade-enabling environment and diversify their production, limit their potential to the supply of one or two commodities thereby perpetuating the trend of huge trade imbalances in favour of South Africa.Originality/Value: This work provides a platform for assessing trade relationships and examining impediments to greater trade. It is also relevant in guiding future research on priority markets in Africa as export destinations and import suppliers in light of increasing regional integration initiatives and governments commitment to

    2010-04-01

    The amount of privately conserved land is increasing worldwide. The potential of these areas to contribute to the global conservation of biodiversity is significant, given that statutory protected areas alone will not suffice. Nevertheless, there is still inadequate support for private conservation areas, and further research on appropriate, flexible, and generally applicable incentive measures is necessary. We conducted 25 semistructured interviews with the owners of private conservation areas in the Little Karoo, South Africa, to examine landowner opinions of existing conservation policies and their relationships with the local conservation authority. We also assessed landowner preferences regarding conservation incentive measures. Landowners doubted the conservation authority's capacity to implement its stewardship program and were also discouraged by the bureaucracy of the program. The conservation authority was often viewed negatively, except where landowners had experienced personal contact from conservation staff or where strong social capital had formed among landowners. Landowners did not desire financial rewards for their conservation efforts, but sought recognition of their stewardship role and greater involvement from the conservation authority through personal contact. We conclude that conservation policies for private lands could benefit from the provision of extension services to landowners, promotion of formation of groups of landowners and other stakeholders, and public acknowledgment of the contributions private conservation areas make.

  12. HIV/AIDS and the construction of Sub-Saharan Africa: heuristic lessons from the social sciences for policy.

    Science.gov (United States)

    Yeboah, Ian E A

    2007-03-01

    There is no doubt that Sub-Saharan African countries face major problems due to the HIV/AIDS pandemic that has ravaged the region. Yet the Eurocentric construction of the region as the source of the virus not only creates negative stereotypes in social science disciplines like geography, but also glosses over the potential of social science disciplines to provide knowledge and influence policy about HIV/AIDS. This oppositional construction of the region has unfortunately contributed to a glossing over of many aspects of Sub-Saharan Africa's people, their environment, culture, history, politics, economics, gender relations, and the region's global status that would provide important input for policy aimed at curbing the devastating spread of HIV in the region. This paper argues that once we recognize that HIV is a global virus with trans-cultural implications, social science disciplines, such as geography, can reveal certain attributes about the region and its HIV/AIDS pandemic that can be used in policy formulation to combat the spread of the virus.

    2014-01-01

    Linoleic acid is the most abundant polyunsaturated fatty acid in human nutrition and represents about 14 g per day in the US diet. Following the discovery of its essential functions in animals and humans in the early 1920's, studies are currently questioning the real requirement of linoleic acid. It seems now overestimated and creates controversy: how much linoleic acid should be consumed in a healthy diet? Beyond the necessity to redefine the dietary requirement of linoleic acid, many questions concerning the consequences of its excessive consumption on human health arise. Linoleic acid is a direct precursor of the bioactive oxidized linoleic acid metabolites. It is also a precursor of arachidonic acid, which produces pro-inflammatory eicosanoids and endocannabinoids. A majority of the studies on linoleic acid and its derivatives show a direct/indirect link with inflammation and metabolic diseases. Many authors claim that a high linoleic acid intake may promote inflammation in humans. This review tries to (i) highlight the importance of reconsidering the actual requirement of linoleic acid (ii) point out the lack of knowledge between dietary levels of linoleic acid and the molecular mechanisms explaining its physiological roles (iii) demonstrate the relevance of carrying out further human studies on the single variable linoleic acid.

    Full Text Available There is evidence that isolated maternal hypothyroxinemia may have detrimental effects on both mother and foetus. Nonetheless, this condition is still far from being universally accepted as a separate thyroid disease, and a standard definition of this state of mild thyroid underfunction is still lacking. We will review the biochemical criteria used to define isolated maternal hypothyroxinemia, together with current methodological issues related to FT4 assays. We will also discuss its epidemiological impact in both iodine-deficient and-sufficient areas, and the effectiveness of iodine prophylaxis on maternal thyroid function and neuropsychomotor development in offspring.

    2016-04-01

    There is marked subseasonal variability over South America and southern Africa. Based on previous work showing that a teleconnection exists between the South American monsoon system and interannual summer rainfall variability over southern Africa, this study shows teleconnections between subseasonal variability over these landmasses. Observed daily gauge precipitation data for 1970-1999 are gridded to 1° resolution for South America and 2.5° for South Africa. At each grid point, anomalies of daily precipitation are calculated and submitted to a bandpass Lanczos filter to isolate subseasonal oscillations in the 20-90 day band. For each season, the filtered precipitation anomalies for the South African grid boxes are correlated with filtered precipitation anomalies in the grid boxes over South America. Lags from 0 up to 12 days are applied to the South African data, in order to investigate convection anomalies over South America that could produce atmospheric perturbations associated with South African precipitation anomalies. The significance of correlation between the filtered data takes autocorrelation into account and uses effective sample sizes. The results shown represent the best correlations for different climatic regimes such as the winter-rainfall dominated southwestern Cape, the all season rainfall South Coast and the summer-rainfall dominated Limpopo region. NCEP re-analyses are used to composite subseasonal anomalies in OLR, 200 hPa streamfunction, and vertically integrated moisture flux associated with precipitation anomaly above one standard deviation in the filtered series (positive phases) of the South African selected regions. The possible origin of the atmospheric circulation anomalies associated with those positive phases is determined using influence functions (IFs) of a vorticity equation model with a divergence source. The model is linearized about a realistic basic state and includes the divergence of the basic state and the advection of

  4. Raising Crop Productivity in Africa through Intensification

    Directory of Open Access Journals (Sweden)

    Zerihun Tadele

    2017-03-01

    Full Text Available The population of Africa will double in the next 33 years to reach 2.5 billion by 2050. Although roughly 60% of the continent’s population is engaged in agriculture, the produce from this sector cannot feed its citizens. Hence, in 2013 alone, Africa imported 56.5 million tons of wheat, maize, and soybean at the cost of 18.8 billion USD. Although crops cultivated in Africa play a vital role in their contribution to Food Security, they produce inferior yields compared to those in other parts of the world. For instance, the average cereal yield in Africa is only 1.6 t·ha−1 compared to the global 3.9 t·ha−1. Low productivity in Africa is also related to poor soil fertility and scarce moisture, as well as a variety of insect pests, diseases, and weeds. While moisture scarcity is responsible for up to 60% of yield losses in some African staple cereals, insect pests inflict annually substantial crop losses. In order to devise a strategy towards boosting crop productivity on the continent where food insecurity is most prevalent, these production constraints should be investigated and properly addressed. This review focuses on conventional (also known as genetic intensification in which crop productivity is raised through breeding for cultivars with high yield-potential and those that thrive well under diverse and extreme environmental conditions. Improved crop varieties alone do not boost crop productivity unless supplemented with optimum soil, water, and plant management practices as well as the promotion of policies pertaining to inputs, credit, extension, and marketing. Studies in Kenya and Uganda have shown that the yield of cassava can be increased by 140% in farmers’ fields using improved varieties and management practices. In addition to traditional organic and inorganic fertilizers, biochar and African Dark Earths have been found to improve soil properties and to enhance productivity, although their availability and affordability to

    There is a dearth of data on end-stage renal disease (ESRD) in Africa. Several national renal registries have been established but have not been sustainable because of resource limitations. The African Association of Nephrology (AFRAN) and the African Paediatric Nephrology Association (AFPNA) recognize the importance of good registry data and plan to establish an African Renal Registry. This article reviews the elements needed for a successful renal registry and gives an overview of renal registries in developed and developing countries, with the emphasis on Africa. It then discusses the proposed African Renal Registry and the first steps towards its implementation. A registry requires a clear purpose, and agreement on inclusion and exclusion criteria, the dataset and the data dictionary. Ethical issues, data ownership and access, the dissemination of findings and funding must all be considered. Well-documented processes should guide data collection and ensure data quality. The ERA-EDTA Registry is the world's oldest renal registry. In Africa, registry data have been published mainly by North African countries, starting with Egypt and Tunisia in 1975. However, in recent years no African country has regularly reported national registry data. A shared renal registry would provide participating countries with a reliable technology platform and a common data dictionary to facilitate joint analyses and comparisons. In March 2015, AFRAN organized a registry workshop for African nephrologists and then took the decision to establish, for the first time, an African Renal Registry. In conclusion, African nephrologists have decided to establish a continental renal registry. This initiative could make a substantial impact on the practice of nephrology and the provision of services for adults and children with ESRD in many African countries.

    Africa is the second largest and most populated continent after Asia. Geographically it is located between the Atlantic and Indian Oceans. Most of the Africa's most populated and industrialized cities are located along the coast of the continent facing the Atlantic and Indian Oceans, example of such cities include Casablanca, Dakar, Accra, Lagos, Luanda and Cape town all facing the Atlantic Ocean and cities like East London, Durban, Maputo, Dar-es-salaam and Mogadishu are all facing the Indian Ocean. As a result of the geographical locations of African Coastal Cities plus increase in their population, industries, sea port operations, petroleum exploration activities, trafficking of toxic wastes and improper waste management culture lead to the incessant increase in the pollution of the two oceans. NATURE OF POLLUTION OF THE ATLANTIC OCEAN i. The petroleum exploration activities going on along the coast of "Gulf of Guinea" region and Angola continuously causes oil spillages in the process of drilling, bunkering and discharging of petroleum products in the Atlantic Ocean. ii.

    The introduction to this description of emigration dynamics in sub-Saharan Africa notes that the region is characterized by intensive migration caused by such factors as population growth, negative economic growth, ethnic conflict, and human rights abuses. The second section of the report discusses the fragmentary and incomplete nature of data on international migration in the region, especially data on conventional migration. Section 3 looks at demographic factors such as high population growth, illiteracy levels, HIV seroprevalence, and urbanization which lead to high unemployment and emigration. The fourth section considers the effects of the rapid expansion of education which is outstripping the absorptive capacity of the economies of many countries. Unemployment is a serious problem which is projected to become worse as increases in employment opportunities continue to lag behind increases in output. Sections five, six, and seven of the report describe relevant economic factors such as per capita income, income distribution, the economic resource base, and economic development; poverty; and the effects of economic adjustment programs, especially on employment opportunities and wages in the public and private sectors. The next section is devoted to sociocultural factors influencing migration both on the micro- and the macro-levels, including the influence of ethnicity and ethnic conflicts as well as the domination of leadership positions by members of minority groups. The political factors discussed in section 9 include women's status, repressive regimes, political instability which leads to underdevelopment, and the policies of the Organization of African Unity which broadened the definition of refugees and set inviolable borders of member states identical to those inherited upon independence. Section 10 outlines ecological factors contributing to migration, including the decline in acreage of arable land, soil deterioration, poor land management, and the

    The French army is often engaged in stability and support operations in Africa, and its military health service has gained much experience. The goal of this article is to present our military medical management strategies during the two main phases of military action. These situations most often begin with an initial combat phase, with combat casualty care. This consists of first aid, i.e., treatment of bleeding points, followed by battlefield forward medical care, damage control surgery, and resuscitation in forward surgical units. The quieter second phase of peacekeeping operations is dominated by the management of tropical diseases and their prevention, essential for the preservation of the military strength.

  19. Out of Africa: High aerosol concentrations in the upper troposphere over Africa

    2003-05-01

    Full Text Available In the year 2000, six flights (three southbound and three northbound of the CARIBIC project were conducted between Germany and two destinations in the southern hemisphere (Windhoek, Namibia and Cape Town, South Africa. In the present report, results on particle number concentrations are discussed in three size ranges (>4 nm, >12 nm, and >18 nm particle diameter during the unique transequatorial Africa flights. The flights covered a total of about 80 h in May, July, and December. Thus, no claim can be made for long-term representativeness of the aerosol data. Nevertheless, they are the first upper systematic tropospheric transequatorial aerosol profiles over Africa. The average aerosol results show a broad maximum, roughly symmetrical to the equator, which compares well in latitudinal extent to a maximum of CO concentrations measured on the same flights. This export of continental surface aerosol to the upper troposphere will be dispersed on a global scale both with the easterly flow near the equator and with the westerlies in the adjacent subtropical regions. There was strong evidence of recent new particle formation before aerosol arrival at flight level, in particular during the time periods between 9:00 and 13:00 local time over Africa. Direct and indirect climate effects of the respective particulate matter remain to be investigated by future flights with the ongoing extension of the CARIBIC payload towards size-resolved measurements above 100 nm particle diameter. At the same time global chemical transport models and aerosol dynamics models need to be extended to be able to reproduce the CARIBIC findings over Africa.

    The Republic of South Africa (RSA) is home to approximately 37 million people, were the highest population density is in the central industrial area. The RSA is rich in minerals, which are the main source of national prosperity. However, the country lacks a plentiful supply of water and is subject to periodic droughts. The RSA can be classified as a water stressed country, and this is the factor which has a major influence on development. The limited and variable supply of water sensitises the RSA to changes in climate, especially rainfall. Hence the RSA has a vested interest in climate change, particularly as the outputs of some current theoretical models predict a lowering of rainfall over an already drought prone central southern Africa. The population can be broadly apportioned into two groups; a first world component with a standard of living approaching that of Europe/USA, and a third world component whose living standard need to be increased. The development of this latter group, many of whom live below the poverty line, is of high priority and will require an expansion of the economy, and consequently may result in increased greenhouse gas emissions in the medium term.

  15. Defining 'plain language' in contemporary South Africa

    2015-12-01

    Full Text Available Defining the concept ‘plain language’ has been hugely problematic since the origins of the so-called Plain Language Movement in the 1970s in the United States and elsewhere in the world. Definitions of ‘plain language’ abound, yet James (2008: 6 warns, in relation to plain language practitioners, that “we can’t yet call ourselves a coherent field, let alone a profession, while we offer such varying definitions of what we do”. Contemporary international definitions of ‘plain language’ are of three types: numerical (or formula-based, elements-focused, or outcomes-focused (Cheek 2010. In South Africa, protective legislation gave rise to a local definition of ‘plain language’ which was widely acclaimed for its comprehensiveness and practicality. From a textlinguistic angle, this article ruminates on the nature of the definition of ‘plain language’ in the National Credit Act (2005 and the Consumer Protection Act (2008, and critically appraises the value of the definition as a sharp and reliable conceptual tool for use by plain language practitioners – as applied linguists – in the absence of norms, standards or guidelines for the use of plain language in the consumer industry in contemporary South Africa.

    The region of North Africa (NA) represents a striking locality regarding migration with several migration patterns, namely emigration in the form of labour export to Europe and North America and, to a lesser extent, to the Arab Gulf area. The latter has increased enormously in the last decade because of the political instability in most of the NA countries. The aim of the present chapter was to explore the patterns of migration stocks and flows in NA countries, based on several websites, systematic review of journals, comparable data available by the United Nations and by the International Organization of Migration. The NA region has become an area of transit migration and labour migration. Emigrant flows from NA countries towards Europe and North America are increasing this decade more than towards the Arab Gulf countries after being replaced by Asian labour. The recent increase in the proportion of women among the migrant population is remarkable. Remittances sent by African migrants have become an important source of external finance for countries of origin. Transient and irregular migration to Egypt originates at the borders with Sudan, Palestine and Libya with destination to the Euro Mediterranean countries. In Tunisia and Morocco, irregular migrants originate from Sub-Saharan Africa to the northern borders. The NA countries serve as departure rather than destination countries, and migration flows to the Euro-Mediterranean countries through legal or illegal routes.

    Full Text Available Background: Leopards (Panthera pardus show genetically determined colour variation. Erythristic (strawberry morphs, where individuals are paler and black pigment in the coat is replaced by a red-brown colour, are exceptionally rare in the wild. Historically, few records exist, with only five putative records known from India.Objectives: To record the presence of erythristic leopards in our study site (Thaba Tholo Wilderness Reserve, Mpumalanga and to collate records from across South Africa. Method: A network of camera traps was used to record individual leopards at Thaba Tholo. We also surveyed local experts, searched the popular South African press, and used social media to request observations.Results: Two out of 28 individual leopards (7.1% recorded in our study site over 3 years were of this colour morph. We obtained records of five other erythristic leopards in the North West and Mpumalanga regions, with no reports outside of this population.Conclusions: Erythristic leopards are widely dispersed across north-east South Africa, predominantly in the Lydenburg region, Mpumalanga. The presence of this rare colour morph may reflect the consequences of population fragmentation.

    Despite the virtual revolution, the mainstream academic community in most countries remains largely ignorant of the potential of web-based teaching resources and of the expansion of open source software, hardware and rapid prototyping. In the context of Biomedical Engineering (BME), where human safety and wellbeing is paramount, a high level of supervision and quality control is required before open source concepts can be embraced by universities and integrated into the curriculum. In the meantime, students, more than their teachers, have become attuned to continuous streams of digital information, and teaching methods need to adapt rapidly by giving them the skills to filter meaningful information and by supporting collaboration and co-construction of knowledge using open, cloud and crowd based technology. In this paper we present our experience in bringing these concepts to university education in Africa, as a way of enabling rapid development and self-sufficiency in health care. We describe the three summer schools held in sub-Saharan Africa where both students and teachers embraced the philosophy of open BME education with enthusiasm, and discuss the advantages and disadvantages of opening education in this way in the developing and developed world.

  19. Drivers for animal welfare policies in Africa.

    Science.gov (United States)

    Molomo, M; Mumba, T

    2014-04-01

    Livestock in Africa represent on average 30% of the agricultural gross domestic product (GDP) and about 10% of the national GDP. Up to 300 million people depend on livestock for their income and livelihood. Accordingly, livestock are considered to be important for the African continent. Despite this, little or no provision for animal welfare is made in the laws and regulations of most African countries. However, the World Organisation for Animal Health (OIE) Performance of Veterinary Services (PVS) Tool includes animal welfare as a critical competency in Veterinary Services, and most African countries have now conducted PVS appraisals. The development of a Regional Animal Welfare Strategy in Africa is also important because it will provide opportunities for full engagement by all relevant parties. Key elements in this process should include collaboration and coordination in information dissemination to all stakeholders, who should include all those in the value chain. The roles played by the OIE Member Delegates and Focal Points, and non-governmental organisations (NGOs), in driving animal welfare policy in most African countries are notable. Without a level of understanding of animal welfare that is sufficient to support clear animal welfare policy development and implementation, problems may appear in the near future which could jeopardise the attainment of increased animal productivity and product quality. This may have negative implications for economic growth and for national and international trade.

  20. Islamic marriages in South Africa: Quo vadimus?

    C. Rautenbach

    2004-07-01

    Full Text Available Due to their potentially polygamous nature, Islamic marriages are not recognised in terms of South African law. The consequences of this non-recognition have been particularly unfair to Muslim women. Until 2000 a Muslim woman had no claim for loss of support if her husband was unlawfully killed. Even today she cannot claim maintenance from her husband after a divorce; she is not an intestate beneficiary after the death of her husband; can be compelled to give evidence against her husband in criminal proceedings and can not claim financial support during the course of her marriage. Since early times there have been calls for the recognition of Islamic marriages. The 1996 Constitution of South Africa protects, among other rights, cultural and religious rights and makes provision for the recognition of cultural and religious marriages by means of legislation. This article gives a brief historical overview regarding the position of Islamic marriages in South Africa. Thereafter the current position of Islamic marriages will be discussed, and finally a few comments regarding the future of Islamic marriages will be given.

  1. Plants Africa gave to the World

    Directory of Open Access Journals (Sweden)

    G. Kunkel

    1983-12-01

    Full Text Available Although the flora of Africa is rather poor in plant species when compared to the floras of Tropical America or South-east Asia, this vast continent is the home of a wide range of plants useful to Man. Many of these have become famous in cultivation around the world. Coffee now provides an important source of income for certain countries, and the Yams yield one of the world’s staple foods. The Oil Palm and Cola trees are widely cultivated in Africa itself and elsewhere. African Mahoganies and Ironwoods are much sought after timber trees of excellent quality. Numerous grasses and pulses are well-known for their food value, and some of the native Cucurbitaceae are appreciated additions to our vegetable diet. African plants have also made their contribution to horticulture, ranging from world-famous trees such as the African or Gabon Tulip tree and many of the South African species of Proteaceae to the multitude of East and South African succulents. The present paper provides a survey of the most important of these useful plants and will emphasize the need of further research for forestry and agricultural as well as horticultural purposes, especially as far as some still little-known but potentially important plants species are concerned.

  2. Biofuels and biodiversity in South Africa

    Directory of Open Access Journals (Sweden)

    Patrick J. O’Farrell

    2011-05-01

    Full Text Available The South African government, as part of its efforts to mitigate the effects of the ongoing energy crisis, has proposed that biofuels should form an important part of the country’s energy supply. The contribution of liquid biofuels to the national fuel supply is expected to be at least 2% by 2013. The Biofuels Industrial Strategy of the Republic of South Africa of 2007 outlines key incentives for reaching this target and promoting the development of a sustainable biofuels industry. This paper discusses issues relating to this strategy as well as key drivers in biofuel processing with reference to potential impacts on South Africa’s rich biological heritage.

    Our understanding of many of the broader aspects of biofuels needs to be enhanced. We identify key areas where challenges exist, such as the link between technology, conversion processes and feedstock selection. The available and proposed processing technologies have important implications for land use and the use of different non-native plant species as desired feedstocks. South Africa has a long history of planting non-native plant species for commercial purposes, notably for commercial forestry. Valuable lessons can be drawn from this experience on mitigation against potential impacts by considering plausible scenarios and the appropriate management framework and policies. We conceptualise key issues embodied in the biofuels strategy, adapting a framework developed for assessing and quantifying impacts of invasive alien species. In so doing, we provide guidelines for minimising the potential impacts of biofuel projects on biodiversity.

  3. Do remittances promote financial development in Africa?

    2016-01-01

    The paper seeks to establish whether or not remittances promoted financial developments and explore the traceable causality between remittances and financial developments in some countries in Africa. We examine the association between remittances received and how they affect the availability of credit to private sector, bank deposits intermediated by financial institutions and money supply. We also question whether the development in the financial sector causes higher levels or otherwise of remittances received. This paper uses data on remittance flows to 50 developing countries in Africa from 1990 to 2011 to explore the nexus. The study uses fixed effects and random effect estimations as well as Vector Error Correction Model method on the panel data. The study shows that remittances promote certain aspects of financial development to some extent and better financial system foster receipts of remittances. The effect of causality is seen in the short run and not in the long-run. The study alludes to literature that remittances could promote financial development in the short run and the development of the financial sector helps increase the propensity to remit via formal channels.

  4. Conservation management of large carnivores in Africa

    Directory of Open Access Journals (Sweden)

    M.G.L. Mills

    1991-09-01

    Full Text Available The conservation management of large carnivores in Africa is reviewed. In large protected areas the complexity of the relations between predators and prey, and between competing predators, indicate that these relationships should not be disturbed, even though, superficially, there may seem to be sound reasons to do so. Management action, however, may have to be taken against carnivores that break out of reserves. The related questions of translocation and re-introduction are also complex. Guidelines for considering whether to and how to implement these strategies are presented. It is stressed that adequate follow-up observations should be made after translocating or re- introducing carnivores, so that more information on the success of these strategies can be obtained. Much of Africa comprises rural areas inhabited by pastoralists. It may be possible to manage some large carnivore species in these areas to the mutual benefit of man and beast, but for this type of program to be successful, a well planned public relations campaign is essential.

    iThemba LABS in South Africa is a research facility that, about twenty years ago, started to treat oncological patients with particle beams. Its collaboration with CERN has steadily grown over the years. After becoming a member of the ALICE and ATLAS Collaborations, today iThemba LABS is planning to buy a new medical-use cyclotron proton facility, and is seeking to strengthen its links with CERN and Europe also in this field by collaborating with ENLIGHT. The cyclotron will be dedicated to proton therapy – the only one of its kind in the southern hemisphere.   iThemba LABS (Laboratory for Accelerator Based Sciences) was established near Cape Town, South Africa almost 50 years ago as the continent's base for the Southern Universities Nuclear Institute that is now used mainly for material science research.

  6. Virtual water trade and development in Africa

    Directory of Open Access Journals (Sweden)

    M. Konar

    2013-10-01

    Full Text Available A debate has long existed on the relationships between human population, natural resources, and development. Recent research has expanded this debate to include the impacts of trade; specifically, virtual water trade, or the water footprint of traded commodities. We conduct an empirical analysis of the relationships between virtual water trade, population, and development in Africa. We find that increases in virtual water imports do not lead to increases in population growth nor do they diminish human welfare. We establish a new index of virtual water trade openness and show that levels of undernourishment tend to fall with increased values of virtual water trade openness. Countries with small dam storage capacity obtain a higher fraction of their agricultural water requirements from external sources, which may indicate implicit "infrastructure sharing" across nations. Globally, increased crop exports tend to correlate with increased crop water use efficiency, though this relationship does not hold for Africa. However, internal African trade is much more efficient in terms of embodied water resources than any other region in the world. Thus, internal African trade patterns may be compensating for poor internal production systems.

    Full Text Available Abstract Background End-of-life care research across Africa is under-resourced and under-developed. A central issue in research in end-of-life care is the measurement of effects and outcomes of care on patients and families. Little is known about the experiences of health professionals' selection and implementation of outcome measures (OM in clinical care, research, audit, or teaching in Africa. Methods An online survey was undertaken of those using outcome measures across the region, as part of the PRISMA project. A questionnaire addressing the use of OMs was developed for a similar survey in Europe and adapted for Africa. Participants were sampled through the contacts database of APCA. Invitation emails were sent out in January 2010 and reminders in February 2010. Results 168/301 invited contacts (56% from 24 countries responded, with 78 respondents having previously used OM (65% in clinical practice, 12% in research and 23% for both. Main reasons for not using OM were a lack of guidance/training on using and analysing OM, with 49% saying that they would use the tools if this was provided. 40% of those using OM in clinical practice used POS, and 80% used them to assess, evaluate and monitor change. The POS was also the main tool used in research, with the principle criteria for use being validation in Africa, access to the tool and time needed to complete it. Challenges to the use of tools were shortage of time and resources, lack of guidance and training for the professionals, poor health status of patients and complexity of OM. Researchers also have problems analysing OM data. The APCA African POS was the most common version of the POS used, and was reported as a valuable tool for measuring outcomes. Respondents indicated the ideal outcome tool should be short, multi-dimensional and easy to use. Conclusion This was the first survey on professionals' views on OM in Africa. It showed that the APCA African POS was the most frequently OM used

    Full Text Available Health systems played a key role in the dramatic rise in global life expectancy that occurred during the 20th century, and have continued to contribute enormously to the improvement of the health of most of the world’s population. The health workforce is the backbone of each health system, the lubricant that facilitates the smooth implementation of health action for sustainable socio-economic development. It has been proved beyond reasonable doubt that the density of the health workforce is directly correlated with positive health outcomes. In other words, health workers save lives and improve health. About 59 million people make up the health workforce of paid full-time health workers world-wide. However, enormous gaps remain between the potential of health systems and their actual performance, and there are far too many inequities in the distribution of health workers between countries and within countries. The Americas (mainly USA and Canada are home to 14% of the world’s population, bear only 10% of the world’s disease burden, have 37% of the global health workforce and spend about 50% of the world’s financial resources for health. Conversely, sub-Saharan Africa, with about 11% of the world’s population bears over 24% of the global disease burden, is home to only 3% of the global health workforce, and spends less than 1% of the world’s financial resources on health. In most developing countries, the health workforce is concentrated in the major towns and cities, while rural areas can only boast of about 23% and 38% of the country’s doctors and nurses respectively. The imbalances exist not only in the total numbers and geographical distribution of health workers, but also in the skills mix of available health workers. WHO estimates that 57 countries world wide have a critical shortage of health workers, equivalent to a global deficit of about 2

    Geographically weighted regression (GWR) extends the familiar regression framework by estimating a set of parameters for any number of locations within a study area, rather than producing a single parameter estimate for each relationship specified in the model. Recent literature has suggested that GWR is highly susceptible to the effects of multicollinearity between explanatory variables and has proposed a series of local measures of multicollinearity as an indicator of potential problems. In this paper, we employ a controlled simulation to demonstrate that GWR is in fact very robust to the effects of multicollinearity. Consequently, the contention that GWR is highly susceptible to multicollinearity issues needs rethinking.

  13. The IUD: dispelling the myths and assessing the potential.

    While the IUD is the most widely used method of reversible contraception throughout the rest of the world, it is used by only 1% of women in the US. Misperceptions that inhibit use of the IUD in the US include 1) the belief that the device works as an abortifacient when, in fact, the mechanism of action of copper releasing IUDs is contraceptive; 2) the belief that all IUDs increase risk of pelvic infection when, in fact, the Dalkon shield is the only IUD associated with increased risk because its multifilament tail allowed bacteria to ascend into the uterine cavity; 3) the association of IUD usage with increased risk of ectopic pregnancy despite the evidence that copper-bearing IUDs actually reduce risk of ectopic pregnancy; and 4) fears that IUD prescribers increase their legal liability although these fears can be allayed by reviewing product information with users, obtaining their informed consent to IUD use, and documenting the provision of detailed postinsertion instructions. Both the copper-releasing and the progesterone-containing IUDs provide effective contraception associated with very low pregnancy rates. Complications of use include expulsions, which occur most frequently in the first 3 months of use and are associated with young age of the women, immediate postpartum insertion, nulliparity, and the skill of the clinician. Uterine perforation upon insertion is extremely rare, and risk depends upon clinician skill. Risk of spontaneous abortion increases if IUDs are left in place during pregnancy. The main reason for discontinuation are increased menstrual bleeding and pain in users, although the progesterone IUD is associated with reduced blood loss. Discontinuation is accompanied by a rapid return to fertility. After screening IUD candidates for risk factors, insertion can occur at any time as long as pregnancy is ruled out (with postpartum insertion recommended after 4 weeks). Users should receive detailed instructions about how to check for expulsion. IUDs provide a good longterm alternative to sterilization.

  15. Dispelling Black Hole Pathologies Through Theory and Observation

    Full Text Available Astrophysical black holes are by now routinely identified with metrics representing eter- nal black holes obtained as exact mathematical solutions of Einstein’s field equations. However, the mere existence and discovery of stationary solutions is no guarantee that they can be attained through dynamical processes. If a straightforward physical caveat is respected throughout a spacetime manifold then the ingress of matter across an event horizon is prohibited, in accordance with Einstein’s expectation. As black hole forma- tion and growth would be inhibited, the various pathological traits of black holes such as information loss, closed timelike curves and singularities of infinite mass density would be obviated. Gravitational collapse would not terminate with the formation of black holes possessing event horizons but asymptotically slow as the maximal time dilation between any pair of worldlines tends towards infinity. The remnants might be better described as dark holes, often indistinguishable from black holes except in certain as- trophysically important cases. The absence of trapped surf aces circumvents topological censorship, with potentially observable consequences for astronomy, as exemplified by the remarkable electromagnetic characteristics, extreme energetics and abrupt extinc- tion of quasars within low redshift galaxies.

    Since the discovery of HIV over three decades ago, major efforts have been made to control and perhaps eliminate HIV infection worldwide. During these studies, certain myths or misconceptions about this infectious disease have been emphasized and other potentially beneficial concepts have received less attention. A true long-term solution to HIV infection merits an appreciation of alternative ideas and findings that could be beneficial in the ultimate control of HIV/AIDS. Here, I discuss six issues and call for more attention to the science of HIV and well-designed clinical trials.

    Full Text Available The work presents a linear model of the private market sector of the economy built out of the main blocks of Keynes with some pieces furnished by Kalecki, Kaldor, and Robinson. The author argues that such model is rich in promise by virtue of its scope and that it strips much of the mystery from econometric models and demonstrates the circumstances in which they are likely to perform well or badly. The consistent relations offer hospitable shelter for the theory of income, employment, price level, and income shares in a succinct design. Pedagogically, the elemental ideas are capable of transmission at an early stage in economic studies.

  20. Urban Languages in Africa Stadtsprachen in Afrika

    Full Text Available Against the backdrop of current research on the city, urbanity is understood to be a distinct way of life in which (in the spatial, factual and historical dimensions processes of densification and heterogenization are perceived as acts of sociation. Urbanization is thus understood to include and produce structuration processes autonomously; this also includes autonomous linguistic practices, which are reflected as sediments of everyday knowledge in language and thus create the instruments needed for facilitating and generalizing such urbanization: urban languages. In this conceptual context, which looks at cities in Africa from the point of view of language sociology, two large phases of urbanization can be distinguished in Africa. The first phase is related to trade networks and cultural métissage of small groups of middlemen. The second phase, characterized by efforts to deal with Africa’s colonial history and to catch up with “the world”, presses ahead with the development of an autonomous, authentic modernity. The reconstruction of the development undergone especially by the more recent urban languages raises questions about the connotations of urbanization and modernization in contemporary Africa: on the one hand, dissociation from colonial legacies as well as from the postcolonial political elites, impotent administrations, and tribalist instrumentalizations of language and language policies; on the other, quite the reverse – the creation of autonomous African modernities that include the city (and the state, brought about by the interplay of both local dynamics and global flows. Vor dem Hintergrund aktueller Stadtforschung sowie der Konzeption von Sprache/Sprechen als Wissenssediment und Praxis wird davon ausgegangen, dass Stadtsprachen als Ressourcen und Resultate der Vergesellschaftung des urbanen Raumes anzusehen sind. In diesem konzeptuellen Rahmen können für Afrika zwei große Phasen der Urbanisierung unterschieden werden
