  1. Some Findings Concerning Requirements in Agile Methodologies

    Science.gov (United States)

    Rodríguez, Pilar; Yagüe, Agustín; Alarcón, Pedro P.; Garbajosa, Juan

    Agile methods have appeared as an attractive alternative to conventional methodologies. These methods try to reduce the time to market and, indirectly, the cost of the product through flexible development and deep customer involvement. The processes related to requirements have been extensively studied in literature, in most cases in the frame of conventional methods. However, conclusions of conventional methodologies could not be necessarily valid for Agile; in some issues, conventional and Agile processes are radically different. As recent surveys report, inadequate project requirements is one of the most conflictive issues in agile approaches and better understanding about this is needed. This paper describes some findings concerning requirements activities in a project developed under an agile methodology. The project intended to evolve an existing product and, therefore, some background information was available. The major difficulties encountered were related to non-functional needs and management of requirements dependencies.

  4. Methodological findings in studies on adoptive families

    Directory of Open Access Journals (Sweden)

    Kalus, Alicja

    2014-09-01

    Full Text Available The issue of adoptive families is the object of interest for many researchers, especially outside Polish borders. A critical analysis of previous studies on adoption shows that the scientific value of many of the existing studies raises doubts. The reasons of this are more or less significant methodological weaknesses, which significantly reduce their scientific value. Researchers often focus on the study of individuals in the adoptive family, e.g. mothers only, adopted children only or selected types of relationships within the family e.g. the mother – child relation. There is a little amount of studies on family systems. It seems worthy to note that numerous studies are conducted in the cause-effect model of explaining phenomena in the adoptive family. Such approach to the study of reality, which is the family, is regarded as too big simplification. Therefore, there is an important reason to undertake the scientific discourse on the research methodology on the adoptive family. Discussed in the paper issues include: theoretical models, arrangement of studies, especially the selection of the test group and the research methods used in the study on adoptive families. Conducting scientific research is essential for the adoption practice. Among psychologists-practitioners exists a disturbing belief that working with adoptive families can be based on the experience gained in psychological practice. This fact can be explained by the existing lack of willingness of adoptive families to cooperate in the field of scientific research. Lack of this cooperation significantly limits the access to the study population of adoptive families.

  6. Humor, laughter, and physical health: methodological issues and research findings.

    Science.gov (United States)

    Martin, R A

    2001-07-01

    All published research examining effects of humor and laughter on physical health is reviewed. Potential causal mechanisms and methodological issues are discussed. Laboratory experiments have shown some effects of exposure to comedy on several components of immunity, although the findings are inconsistent and most of the studies have methodological problems. There is also some evidence of analgesic effects of exposure to comedy, although similar findings are obtained with negative emotions. Few significant correlations have been found between trait measures of humor and immunity, pain tolerance, or self-reported illness symptoms. There is also little evidence of stress-moderating effects of humor on physical health variables and no evidence of increased longevity with greater humor. More rigorous and theoretically informed research is needed before firm conclusions can be drawn about possible health benefits of humor and laughter.

  7. Complex adaptive HIV/AIDS risk reduction: Plausible implications from findings in Limpopo Province, South Africa.

    Science.gov (United States)

    Burman, Chris J; Aphane, Marota A

    2016-05-16

    This article emphasises that when working with complex adaptive systems it is possible to stimulate new social practices and/or cognitive perspectives that contribute to risk reduction, associated with reducing aggregate community viral loads. The process of achieving this is highly participatory and is methodologically possible because evidence of 'attractors' that influence the social practices can be identified using qualitative research techniques. Using findings from Limpopo Province, South Africa, we argue that working with 'wellness attractors' and increasing their presence within the HIV/AIDS landscape could influence aggregate community viral loads. While the analysis that is presented is unconventional, it is plausible that this perspective may hold potential to develop a biosocial response - which the Joint United Nations Programme on HIV and AIDS (UNAIDS) has called for - that reinforces the biomedical opportunities that are now available to achieve the ambition of ending AIDS by 2030.

  8. THE PERCEPTIONS OF AGILE METHODOLOGY IN SOUTH AFRICA

    2016-01-01

    Full Text Available Agile methodology was introduced in the mid 90’s while the agile manifesto was adopted in 2001. The rationale behind the introduction of the agile methodology was to uncover better ways of developing software that will meet the user’s expectation in an iterative controlled manner. With technological explosion and rift competition for market share, user experience and satisfaction can only be achieved through proper communication between stakeholders and innovative ways of doing things. Doing things differently is what the agile methodology brought. Despite the existence of this methodology for over 20 years now, South African software industry is only starting to realize its existence with a lot of companies jumping into the bandwagon. This paper presents the results of an empirical research of how the South African software industry perceive the methodology.

    2009-04-01

    Full Text Available Background:To carry out a systematic review of the birth prevalence of cleft lip with or without cleft palate (CLP and cleft palate (CP in Africa based on available published data. Methods:Using the Cochrane search strategy and the following keywords words “cleft palate”, “prevalence”, “incidence”, “cleft lip” and “Africa” to screen Ovid Medline (1966 to March 2007, Cinahl (1982-March 2007, Pub Med, Scopus, and Web-Google. All identified published, prospective and retrospective studies on the birth prevalence of CLP and CP in Africa were included. The dates, location, sources, number of births (live births, still births, number of cleft cases, prevalence rates, sex ratio, cleft types, and clefts with associated anomalies were extracted. Results:Ascertainment of cases was through the hospitals. Overall there were 57 CL/P, 56 CL and 36 CP reported from all the studies. From seven studies combined, 21 males and 20 females had CL, 10 males and 22 females with CP and 26 males and 24 females with CL/P. There were 3 cases with CL/P, 2 with CP and 2 with CL from the three studies that reported clefts with associated anomalies. Conclusion:For an improved ascertainment of cleft cases, there is a need to set up a birth defects surveillance system in the form of a national birth registry. Future studies should then aim to include the entire population in geographically defined regions. Reliable data on incidence is an essential pre-requisite for studies into aetiology and prevention.

    OpenAIRE

    2005-01-01

    The asymmetrical threats that challenge U.S. national policies are not large standing armies, but rather individuals who seek to usurp and coerce U.S. national interests. The nature of today's threats call for the U.S. military to change from finding, fixing, and destroying the enemy's forces to identifying, locating and capturing rogue individuals in order to destroy networks. To counter such threats, the USG will have to quickly and efficiently identify and find these targets globally. ...

  13. School resources and student achievment: worldwide findings and methodological issues

    Directory of Open Access Journals (Sweden)

    Paulo A. Meyer. M. Nascimento

    2008-03-01

    Full Text Available The issues raised in the Education Production Function literature since the US 1966 Coleman Report have fuelled high controversy on the role of school resources in relation to student performance. In several literature reviews and some self estimates, Erik Hanushek (1986, 1997, 2006 systematically affirms that these two factors are not associated one to another – neither in the US nor abroad. In recent cross-country analyses, Ludger Woessmann (2003; 2005a; 2005b links international differences in attainment to institutional differences across educational systems – not to resourcing levels. In the opposite direction, Stephen Heyneman and William Loxley (1982, 1983 tried to demonstrate in the 1980’s that, at least for low income countries, school factors seemed to outweigh family characteristics on the determination of students’ outcomes – although other authors show evidence that such a phenomenon may have existed only during a limited period of the 20th Century. In the 1990s, meta-analyses raised the argument that school resources were sufficiently significant to be regarded as pedagogically important. The turn of the Century witnessed a new movement: the recognition that endogenous determination of resource allocation is a substantial methodological issue. Therefore, efforts have been made to incorporate the decision-making processes that involve families, schools and policy-makers in economic models. This implies changes in research designs that may affect the direction of future policy advices patronised by international development and educational organisations.

  14. Toward Improved Understanding of Food Security: A Methodological Examination Based in Rural South Africa.

    Science.gov (United States)

    Kirkland, Tracy; Kemp, Robert S; Hunter, Lori M; Twine, Wayne S

    2013-03-01

    Accurate measurement of household food security is essential to generate adequate information on the proportion of households experiencing food insecurity, especially in areas or regions vulnerable to food shortages and famine. This manuscript offers a methodological examination of three commonly used indicators of household food security - experience of hunger, dietary diversity, and coping strategies. Making use of data from the Agincourt Health and Demographic Surveillance Site in rural South Africa, we examine the association between the indicators themselves to improve understanding of the different insight offered by each food security "lens." We also examine how the choice of indicator shapes the profile of vulnerable households, with results suggesting that dietary diversity scores may not adequately capture broader food insecurity. Concluding discussion explores programmatic and policy implications as related to methodological choices.

    1978-11-01

    Full Text Available This is a report on the most important findings of a questionnaire survey among employers on the remuneration of Black workers in South Africa. Amongst other things the following was found: - that most of the usual fringe benefits are already fairly generally provided for or that the employers are aware of the need for them; - that wages show a high relationship to job and educational levels and that both of these will have to be raised in order to narrow the wage gap; - that in general employers show a sound approach to the remuneration of their Black employees, but that they apparently are in need of a system by which it may be effectively implemented.OpsommingVerslag word gelewer oor die belangrikste bevindings van 'n vraelysondersoek by werkgewers oor die vergoeding van Swart werknemers in Suid-Afrika.

  19. Drivers of routine immunization coverage improvement in Africa: findings from district-level case studies.

    LaFond, Anne; Kanagat, Natasha; Steinglass, Robert; Fields, Rebecca; Sequeira, Jenny; Mookherji, Sangeeta

    2015-04-01

    There is limited understanding of why routine immunization (RI) coverage improves in some settings in Africa and not in others. Using a grounded theory approach, we conducted in-depth case studies to understand pathways to coverage improvement by comparing immunization programme experience in 12 districts in three countries (Ethiopia, Cameroon and Ghana). Drawing on positive deviance or assets model techniques we compared the experience of districts where diphtheria-tetanus-pertussis (DTP3)/pentavalent3 (Penta3) coverage improved with districts where DTP3/Penta3 coverage remained unchanged (or steady) over the same period, focusing on basic readiness to deliver immunization services and drivers of coverage improvement. The results informed a model for immunization coverage improvement that emphasizes the dynamics of immunization systems at district level. In all districts, whether improving or steady, we found that a set of basic RI system resources were in place from 2006 to 2010 and did not observe major differences in infrastructure. We found that the differences in coverage trends were due to factors other than basic RI system capacity or service readiness. We identified six common drivers of RI coverage performance improvement-four direct drivers and two enabling drivers-that were present in well-performing districts and weaker or absent in steady coverage districts, and map the pathways from driver to improved supply, demand and coverage. Findings emphasize the critical role of implementation strategies and the need for locally skilled managers that are capable of tailoring strategies to specific settings and community needs. The case studies are unique in their focus on the positive drivers of change and the identification of pathways to coverage improvement, an approach that should be considered in future studies and routine assessments of district-level immunization system performance.

    2016-07-01

    The post-earthquake psychopathological investigation (PEPSI) was designed to probe the short-and long-term effects of the earthquake in northern Armenia on 7 December 1988 on survivors' mental and physical health. Four phases of this study have been conducted to date, and, overall, more than 80 per cent of a sub-sample of 1,773 drawn from an initial cohort of 32,743 was successfully followed during 2012. This paper describes the methodology employed in the evaluation, summarises previous findings, details the current objectives, and examines the general characteristics of the sample based on the most recent follow-up phase outcomes. Despite a significant decrease in psychopathology rates between 1990 and 2012, prevalence rates of post-traumatic stress disorder and depression among study participants in 2012 were greater than 15 and 26 per cent, respectively. The paper also notes the strengths and limitations of the study vis-à-vis future research and highlights the importance and potential practical implications of similar assessments and their outcomes.

  7. A methodology to find the elementary landscape decomposition of combinatorial optimization problems.

    Science.gov (United States)

    Chicano, Francisco; Whitley, L Darrell; Alba, Enrique

    2011-01-01

    A small number of combinatorial optimization problems have search spaces that correspond to elementary landscapes, where the objective function f is an eigenfunction of the Laplacian that describes the neighborhood structure of the search space. Many problems are not elementary; however, the objective function of a combinatorial optimization problem can always be expressed as a superposition of multiple elementary landscapes if the underlying neighborhood used is symmetric. This paper presents theoretical results that provide the foundation for algebraic methods that can be used to decompose the objective function of an arbitrary combinatorial optimization problem into a sum of subfunctions, where each subfunction is an elementary landscape. Many steps of this process can be automated, and indeed a software tool could be developed that assists the researcher in finding a landscape decomposition. This methodology is then used to show that the subset sum problem is a superposition of two elementary landscapes, and to show that the quadratic assignment problem is a superposition of three elementary landscapes.

  8. What Can Be Learned From a Laboratory Model of Conceptual Change? Descriptive Findings and Methodological Issues

    Science.gov (United States)

    Ohlsson, Stellan; Cosejo, David G.

    2014-07-01

    The problem of how people process novel and unexpected information— deep learning (Ohlsson in Deep learning: how the mind overrides experience. Cambridge University Press, New York, 2011)—is central to several fields of research, including creativity, belief revision, and conceptual change. Researchers have not converged on a single theory for conceptual change, nor has any one theory been decisively falsified. One contributing reason is the difficulty of collecting informative data in this field. We propose that the commonly used methodologies of historical analysis, classroom interventions, and developmental studies, although indispensible, can be supplemented with studies of laboratory models of conceptual change. We introduce re- categorization, an experimental paradigm in which learners transition from one definition of a categorical concept to another, incompatible definition of the same concept, a simple form of conceptual change. We describe a re-categorization experiment, report some descriptive findings pertaining to the effects of category complexity, the temporal unfolding of learning, and the nature of the learner's final knowledge state. We end with a brief discussion of ways in which the re-categorization model can be improved.

  10. Tuberculosis and hepatic steatosis are prevalent liver pathology findings among HIV-infected patients in South Africa.

    Directory of Open Access Journals (Sweden)

    Christopher J Hoffmann

    Full Text Available Liver disease epidemiology in sub-Saharan Africa has shifted as a result of HIV and the increased use of antiretroviral therapy leading to a need for updated data on common causes of liver disease. We retrospectively reviewed records from all hospitalized patients who had liver biopsy at a single hospital in South Africa from 2001 to 2009 and compared diagnosis by HIV status. During the period of study 262 patients had liver biopsy, 108 (41% were HIV-infected, 25 (10% were HIV-sero-negative, and 129 (49% had unknown or unrecorded HIV status. Overall 81% of biopsies provided additional diagnostic data. Malignancy was the most common finding reported on 56 (21% biopsies followed by granuloma or TB, hepatic steatosis, and fibrosis or cirrhosis. HIV-infected patients were more likely to have granulomas and steatosis. Half of patients with granulomas were already on TB treatment, suggesting paradoxical reactions or drug induced liver injury may have been important causes of liver inflammation among these patients. We note that TB, paradoxical reactions during TB treatment, possible drug induced liver injury, and hepatic steatosis are important causes of liver pathology among HIV-infected hospitalized patients with unclear etiology of liver disease after initial assessment. Among HIV sero-negative patients, malignancy was the major cause of liver disease. Our findings re-enforce the importance of TB as a diagnosis among HIV-infected individuals.

    Full Text Available To enhance research surveying in software methodologies, a model is introduced that can indicate field maturity based on vocabulary and relevant literature. This model is developed by drawing analogies with software methodologies. Two analogies are used: software models and software life cycles or processes. How this model can reduce research surveying problems for researchers is described using extracts from application results as examples. Although the model does support research surveying activities, it cannot choose the subject for the researcher.

    Hongoro, C; Mturi, A J; Kembo, J

    2008-12-01

    National AIDS councils (NACs) were established in many African countries to co-ordinate the multi-sectoral response to HIV/ AIDS. Their main mandate is to provide strategic leadership and co-ordinate activities geared to fight against HIV/AIDS. This study sought to understand the extent to which NACs have achieved their goals and the challenges they face. Best practices were identified and shared among countries involved, so as to enhance their efforts. This review is crucial given that the fight against HIV/AIDS is far from being won. Data for this study were collected from five countries: Ghana, Tanzania, Kenya, Zimbabwe and Lesotho. A qualitative study approach was employed by conducting individual in-depth interviews with senior staff members of NACs. We also collected important NAC documents that are used in achieving their mandates. The NAC documentation seemed to be in order in all countries visited, and there was a good understanding of the NACs' mandate and their functioning. There were numerous constraints and challenges that need to be addressed in order to make NACs perform their activities better. NACs need to operate independently of the usual government bureaucracy. Additional work is still needed by governments in making NACs responsible for the multi-sectoral response in sub-Saharan Africa.

    Full Text Available Introduction: Sex workers, people who use drugs, men who have sex with men, women who have sex with women and transgender people in South Africa frequently experience high levels of stigma, abuse and discrimination. Evidence suggests that such abuse is sometimes committed by police officers, meaning that those charged with protection are perpetrators. This reinforces cycles of violence, increases the risk of HIV infection, undermines HIV prevention and treatment interventions and violates the constitutional prescriptions that the police are mandated to protect. This paper explores how relationship building can create positive outcomes while taking into account the challenges associated with reforming police strategies in relation to key populations, and vice versa. Discussion: We argue that relationships between law enforcement agencies and key populations need to be re-examined and reconstituted to enable appropriate responses and services. The antagonistic positioning, “othering” and blame assignment frequently seen in interactions between law enforcement officials and key populations can negatively influence both, albeit for different reasons. In addressing these concerns, we argue that mediation based on consensual dialogue is required, and can be harnessed through a process that highlights points of familiarity that are often shared, but not understood, by both parties. Rather than laying blame, we argue that substantive changes need to be owned and executed by all role-players, informed by a common language that is cognisant of differing perspectives. Conclusions: Relational approaches can be used to identify programmes that align goals that are part of law enforcement, human rights and public health despite not always being seen as such. Law enforcement champions and representatives of key populations need to be identified and supported to promote interventions that are mutually reinforcing, and address perceived differences by

    The SIRT (Simultaneous Iterative Reconstruction Technique) algorithm is commonly used in Electron Tomography to calculate the original volume of the sample from noisy images, but the results provided by this iterative procedure are strongly dependent on the specific implementation of the algorithm, as well as on the number of iterations employed for the reconstruction. In this work, a methodology for selecting the iteration number of the SIRT reconstruction that provides the most accurate segmentation is proposed. The methodology is based on the statistical analysis of the intensity profiles at the edge of the objects in the reconstructed volume. A phantom which resembles a a carbon black aggregate has been created to validate the methodology and the SIRT implementations of two free software packages (TOMOJ and TOMO3D) have been used.

    Cystic Echinococcosis is a parasitic disease caused by the cestode Echinococcus granulosus widely distributed in Africa. Monitoring of this parasite requires access to cyst samples on intermediate hosts observed at the slaughterhouse. In order to facilitate sampling in the field and analysis, the French National Reference Laboratory for Echinococcus spp. has developed a tissue derived from DNA sampling with FTA(®) card technology. The DNA samples were taken by applying the FTA(®) paper on the germinal layer after opening the cysts. The sampling technique was validated using frozen cysts (n = 76) stored in the laboratory and from field samples (n = 134) taken at the slaughterhouse by veterinarian technicians during meat inspection in Morocco, Mali and Mauritania. DNA was extracted after several weeks of storage at room temperature. PCR assays were performed using primers for generic cestode (cox1) and amplified fragments were sequenced. All samples taken in the lab and 80% of field samples were capable of molecular characterization. Cyst-derived DNA from FTA(®) samples can be useful for easy sampling, storage and rapid, safe and cheap shipment. The use of the FTA methodology will facilitate studies in the field to investigate the presence and genetic characterization of E. granulosus sensu lato in African countries.

  19. The Potential Role of Mental Model Methodologies in Multistakeholder Negotiations: Integrated Water Resources Management in South Africa

    Full Text Available Equitable redistribution of resources is an emergent phenomenon in democratizing countries, and attempts are often characterized by decentralized decision making within a framework of multistakeholder negotiations. South Africa offers a unique opportunity to explore the manifestations of these relationships, particularly through Integrated Water Resources Management and its National Water Act of 1998. The Integrated Water Resources Management framework provides for collaborative strategic planning, shared visioning, consideration to water resource protection, attention to the regulation of use, operational planning, and implementation of management plans. Water users, with different stakes and views of how the resource should be managed, are expected to arrive at a single strategic plan for a specific hydrological region. Clearly this complex planning situation creates a need for tools that assist in producing a measure of convergence in thinking and enough of a shared rationale to allow stakeholder participation to produce an integrated management outcome. Several such tools are available in the overall catchment management strategy, but these would benefit from clearer understanding of the positions from which different stakeholders are operating and a way of knowing whether these positions are aligning. In this paper challenges posed by differences in meaning and understanding amongst stakeholders are examined against the need to engage stakeholders in water resources management. We deliberate on the prospects of employing mental model methodologies within the context of the strategic management framework for water management described.

    The use of single-case methodology (SCM) in brain injury rehabilitation is described and contrasted with other methodologies. SCM is optimal when attempting to meet highly individual presentations or to trial innovative solutions. Portable biofeedback is a potentially effective means of helping persons with brain injury to recognise and regulate emotional states. Emotional dysregulation, associated with disinhibition on tests of executive function, is hypothesised to underpin aggressive challenging behaviour and may be amenable to feedback on heart rate variability, a marker for stress. Two case studies of a novel biofeedback intervention, emWave2, to address aggression directed towards the self and towards others are presented. Data from two A-B designs were analysed using the non-overlap all pairs (NAP) statistical method. Clinical significance of outcome is reported in both cases but only Case 2 reached statistical significance. The discussion highlights limitations of the methodology. Results are discussed in relation to the device helping participants differentiate the physiological state associated with stress. The future application of wearable physiological sensing and feedback systems is explored.

  3. How useful are skills acquired at adult non-formal education and training centres for finding employment in South Africa?

    2015-10-01

    Non-formal adult education and training (NFET) in South Africa is instrumental in breaking the high level of poverty and decreasing the social inequality the country continues to face as a post-apartheid democracy. Public and private NFET centres in South Africa aim to meet the training needs of adults who have been deprived of formal education with courses which foster access to opportunities for skills acquisition and employment and bring about social and economic inclusion. However, many adults who were facing long-term unemployment due to a lack of marketable skills remain unemployed after completing NFET programmes. This paper reports on a study which investigated what constitutes favourable conditions ("internal enabling environments") for skills acquisition inside NFET centres leading to employment and how they can be improved to contribute to coordinated efforts of increasing NFET graduates' paid and/or self-employment capacities. The authors found that centres focusing on activities suitable for self-employment during training were more likely to create internal enabling environments for skills acquisition and income generation than centres offering courses designed for entering paid employment. The authors conclude that there appears to be a significant correlation between NFET centres' training programme objectives, financial resources, trainee selection criteria, the process of training needs assessment, and skills acquisition for successful employment outcomes of NFET graduates. Without these internal enabling factors, adult trainees are likely to continue finding it difficult to integrate into the labour market or participate in economic activities and hence break the cycle of poverty and social exclusion.

    Paraquat is a bipyridylium non-selective contact herbicide commonly used worldwide. When ingestion occurs by humans and animals either accidentally, intentionally or maliciously, paraquat selectively accumulates in the lungs resulting in the production of oxygen-free radicals, causing membrane damage and cell death. Intoxicated subjects typically show progressive and fatal pulmonary haemorrhage, collapse and oedema. In individuals surviving the acute phase, pulmonary fibrosis develops. Gastrointestinal-, renal- and central nervous system clinical signs may also occur. Owing to the lack of effective treatment and absence of an antidote, the prognosis is poor. The clinical presentation, clinicopathological findings and treatment are briefly described of three dogs from one South African household, intoxicated with paraquat. Macroscopic and microscopic lesions in one dog that was necropsied, as well as pulmonary ultrastructure are detailed and illustrated for academic reference. All dogs presented with tachypnoea and dyspnoea 2-3 days after accidental paraquat ingestion. Treatment was aimed at reducing gastrointestinal absorption, enhancing elimination by diuresis and avoiding further oxidative damage by administration of antioxidants. All dogs, however, became progressively hypoxic despite treatment and were euthanised. Paraquat toxicity should be a differential diagnosis in dogs with unexplained progressive respiratory and gastrointestinal signs and renal failure. The local veterinary profession should be aware of accidental or intentional paraquat toxicity of animals. Existing literature, variations possible in canine clinical signs, measured parameters, lesions, as well as possible treatments, promising experimental antidotes and management options are discussed.

    2016-12-01

    Here we develop and demonstrate a three-step strategy for finding a safe landing ellipse for a legged spacecraft on a small body such as an asteroid or planetary satellite. The first step, acquisition of a high-resolution terrain model of a candidate landing region, is simulated using existing statistics on block abundances measured at Phobos, Eros, and Itokawa. The synthetic terrain model is generated by randomly placing hemispheric shaped blocks with the empirically determined size-frequency distribution. The resulting terrain is much rockier than typical lunar or martian landing sites. The second step, locating a landing ellipse with minimal hazards, is demonstrated for an assumed approach to landing that uses Autonomous Landing and Hazard Avoidance Technology. The final step, determination of the probability distribution for orientation of the landed spacecraft, is demonstrated for cases of differing regional slope. The strategy described here is both a prototype for finding a landing site during a flight mission and provides tools for evaluating the design of small-body landers. We show that for bodies with Eros-like block distributions, there may be >99% probability of landing stably at a low tilt without blocks impinging on spacecraft structures so as to pose a survival hazard.

  10. Comparing verbal autopsy cause of death findings as determined by physician coding and probabilistic modelling: a public health analysis of 54 000 deaths in Africa and Asia

    2015-06-01

    Full Text Available Background: Coverage of civil registration and vital statistics varies globally, with most deaths in Africa and Asia remaining either unregistered or registered without cause of death. One important constraint has been a lack of fit–for–purpose tools for registering deaths and assigning causes in situations where no doctor is involved. Verbal autopsy (interviewing care–givers and witnesses to deaths and interpreting their information into causes of death is the only available solution. Automated interpretation of verbal autopsy data into cause of death information is essential for rapid, consistent and affordable processing. Methods: Verbal autopsy archives covering 54182 deaths from five African and Asian countries were sourced on the basis of their geographical, epidemiological and methodological diversity, with existing physician–coded causes of death attributed. These data were unified into the WHO 2012 verbal autopsy standard format, and processed using the InterVA–4 model. Cause–specific mortality fractions from InterVA–4 and physician codes were calculated for each of 60 WHO 2012 cause categories, by age group, sex and source. Results from the two approaches were assessed for concordance and ratios of fractions by cause category. As an alternative metric, the Wilcoxon matched–pairs signed ranks test with two one–sided tests for stochastic equivalence was used. Findings: The overall concordance correlation coefficient between InterVA–4 and physician codes was 0.83 (95% CI 0.75 to 0.91 and this increased to 0.97 (95% CI 0.96 to 0.99 when HIV/AIDS and pulmonary TB deaths were combined into a single category. Over half (53% of the cause category ratios between InterVA–4 and physician codes by source were not significantly different from unity at the 99% level, increasing to 62% by age group. Wilcoxon tests for stochastic equivalence also demonstrated equivalence. Conclusions: These findings show strong concordance

    DNA microarray technology is a high throughput and parallel technique for genomic investigation due to its advantages of simul-taneously surveying features of large scales complex data in biology. This paper aims to find feature subset to build the classifier for gene expression data analysis. At first, K-means clustering algorithm was carried out on the dataset of yeast cell cycle. Based on Rand cal-culation, a statistical method was used to pick out the data points (genes) for classifier design. Meanwhile, the principal component anal-ysis was applied to help to construct the classifier. For the validation of classifier built and prediction of a target subset of genes, discriminant analysis in terms of partial least square regression and artificial neural network were also performed.

    The concept of joint implementation as a way to implement climate change mitigation projects in another country has been controversial ever since its inception. Developing countries have raised numerous issues at the project-specific technical level, and broader concerns having to do with equity and burden sharing. This paper summarizes the findings of studies for Brazil, India, Mexico and South Africa, four countries that have large greenhouse gas emissions and are heavily engaged in the debate on climate change projects under the Kyoto Protocol. The studies examine potential or current projects/programs to determine whether eight technical concerns about joint implementation can be adequately addressed. They conclude that about half the concerns were minor or well managed by project developers, but concerns about additionality of funds, host country institutions and guarantees of performance (including the issues of baselines and possible leakage) need much more effort to be adequately addressed. All the papers agree on the need to develop institutional arrangements for approving and monitoring such projects in each of the countries represented. The case studies illustrate that these projects have the potential to bring new technology, investment, employment and ancillary socioeconomic and environmental benefits to developing countries. These benefits are consistent with the goal of sustainable development in the four study countries. At a policy level, the studies' authors note that in their view, the Annex I countries should consider limits on the use of jointly implemented projects as a way to get credits against their own emissions at home, and stress the importance of industrialized countries developing new technologies that will benefit all countries. The authors also observe that if all countries accepted caps on their emissions (with a longer time period allowed for developing countries to do so) project-based GHG mitigation would be significantly

    In 1997, at the Davos International Economic Forum, Nelson Mandela stated that "the poor, the vulnerable, the unschooled, the socially marginalized, the women, and the children, those who bear the burden of colonial legacy-these are the sectors of society which bear the burden of AIDS" (Richter, 2001). Nearly a decade later, that statement still holds true, especially in Mr. Mandela's home country. South Africa continues to have one of the world's highest prevalence ratios of HIV infection (UNAIDS, 2002). This paper explores the significance of perceptions, knowledge, practices, and attitudes toward HIV/AIDS in two important groups in South Africa: health care providers based in public health clinics and their patients. This paper will assess the provider-patient interaction from the perspective of members of the South African HIV/AIDS treatment and prevention community. The analysis will examine the results of in-depth interviews and focus group discussions with providers and patients, respectively, in two of South Africa's nine provinces. Between December 2002 and April 2003 in Guateng and KwaZulu-Natal provinces, we conducted (1) in-depth interviews of a spectrum of health care providers at five local public health clinics and (2) focus groups of patients who patronize those clinics. The results show that there are gaps in the HIV/AIDS knowledge of some of the health care providers and that the participants' health beliefs and practices are embedded in the social conditions in which they live and work, which has a ripple effect on their risk behaviors and trumps any intervention messages from their health care providers and larger public health intervention messages.

    Sustainable development in Africa is dependent on increasing use of the continent's water resources without significantly degrading ecosystem services that are also fundamental to human wellbeing. This is particularly challenging in Africa because of high spatial and temporal variability in the availability of water resources and limited amounts of total water availability across expansive semi-arid portions of the continent. The challenge is compounded by ambitious targets for increased water use and a rush of international funding to finance development activities. Balancing development with environmental sustainability requires (i) understanding the boundary conditions imposed by the continent's climate and hydrology today and into the future, (ii) estimating the magnitude and spatial distribution of water use needed to meet development goals, and (iii) understanding the environmental water requirements of affected ecosystems, their current status and potential consequences of increased water use. This article reviews recent advancements in each of these topics and highlights innovative approaches and tools available to support sustainable development. While much remains to be learned, scientific understanding and technology should not be viewed as impediments to sustainable development on the continent.

    2008-01-01

    Full Text Available The past ten years have seen the field of information and knowledge management develop and implement new and improved technologies. Because of the ease with which information is exchanged the contribution to information overload has increased exponentially and the need for information and knowledge management is more real than ever before. Research in itself is a science of knowledge creation that continuously evolves in line with newly developed theories and research methodologies. An investigation of the theories and research methodologies that doctoral theses, completed in South Africa, ascribed to over the past ten years were conducted. Search strings containing 'information management', 'knowledge management' and 'information and knowledge management' were searched within citation, abstract and subject fields. A sample of 30 theses from a possible 47 in the relevant population was identified. Qualitative and mixed methods research design was favoured, making use of case studies and surveys, but paying little attention to theoretical approaches or paradigms. The boundaries between disciplines are continuously re-defined, new disciplines evolve and traditional disciplines suffer under the pressures of changing problems of the world. The importance of research in the field of information and knowledge management being grounded in the most recent scientific thought is emphasized.

    Full Text Available Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird Harmonia axyridis and for its potential use in studies of co-evolution and pathogen spread. We collected adults from ten species of ladybirds in the Western Cape Province, South Africa, and screened for the presence of H. virescens. Infections with H. virescens were found in the samples of two species, H. axyridis and the native Cheilomenes propinqua. This marks the first record of H. virescens on H. axyridis from the African continent and the first record on Cheilomenes worldwide.

    This article presents the results of a randomized trial in South Africa of an adapted evidence-based Woman-Focused intervention on condom use with primary sex partners. The preliminary findings show that regardless of HIV status, condom negotiation was significantly associated with condom use at the 3- and 6-month follow-ups. By intervention group, significant intervention effects were found at 6-month follow-up for HIV-positive and HIV-unknown status women in the Woman-Focused intervention who were more likely than women in the Standard intervention to report condom use with a primary male partner. Among HIV-positive women, those in the Woman-Focused group and those with greater sexual control were more likely to report condom use at the 6-month follow-up. The findings indicate that gender-based interventions for women may result in increased condom negotiation skills.

    Full Text Available INTRODUCTION: Findings regarding the association between overweight and all-cause mortality range from significantly lower to higher risk, compared with body-mass-index (BMI within the "normal" range. METHODS: We examined empirically potential methodological explanations for these apparently conflicting results using questionnaire and linked mortality data from 246,314 individuals aged ≥45 years in the Australian 45 and Up Study (11,127 deaths; median follow-up 3.9 years. Hazard ratios (HR for all-cause mortality associated with BMI were modelled according to different methods of accounting for illness at baseline, finer versus broader gradations of BMI and choice of reference group, adjusting for potential confounders. RESULTS: In analyses using the broad World Health Organization (WHO categories, the all-cause mortality HR was significantly lower in the overweight category (25.0-29.99 kg/m², than the normal weight (18.5-24.99 kg/m² category. However, in analyses accounting for baseline illness, which excluded those with pre-existing illness at baseline, ever-smokers and the first 2 years of follow up, absolute age-standardised mortality rates varied up to two-fold between finer BMI categories within the WHO normal weight category; rates were lowest at 22.5-24.99 kg/m² and mortality HRs increased steadily for BMI above (p(trend<0.02 and below (p(trend<0.003 this reference category. Hence, the breadth of the BMI categories used and whether or not baseline illness is accounted for explain the apparent discrepancies between reported BMI-mortality associations. CONCLUSION: Using fine BMI categories and the category with the lowest absolute rates as the reference group and accounting for the potential confounding effects of baseline illness is likely to yield the most reliable risk estimates for establishing the independent relationship of BMI to all-cause mortality. These results and those of other studies indicate that a BMI of 22.5-24.99 kg

    The Energy Independence and Security Act of 2007 (Public Law 110-140) authorized the U.S. Geological Survey (USGS) to conduct a national assessment of geologic storage resources for carbon dioxide (CO2) and requested that the USGS estimate the "potential volumes of oil and gas recoverable by injection and sequestration of industrial carbon dioxide in potential sequestration formations" (121 Stat. 1711). The USGS developed a noneconomic, probability-based methodology to assess the Nation's technically assessable geologic storage resources available for sequestration of CO2 (Brennan and others, 2010) and is currently using the methodology to assess the Nation's CO2 geologic storage resources. Because the USGS has not developed a methodology to assess the potential volumes of technically recoverable hydrocarbons that could be produced by injection and sequestration of CO2, the Geologic Carbon Sequestration project initiated an effort in 2010 to develop a methodology for the assessment of the technically recoverable hydrocarbon potential in the sedimentary basins of the United States using enhanced oil recovery (EOR) techniques with CO2 (CO2-EOR). In collaboration with Stanford University, the USGS hosted a 2-day CO2-EOR workshop in May 2011, attended by 28 experts from academia, natural resource agencies and laboratories of the Federal Government, State and international geologic surveys, and representatives from the oil and gas industry. The geologic and the reservoir engineering and operations working groups formed during the workshop discussed various aspects of geology, reservoir engineering, and operations to make recommendations for the methodology.

    Cape Town, South Africa experienced an upsurge in the level of political violence from May to July of 1986. To determine the impact of the political violence on health and health services, selected routinely available information was analyzed, a community survey was conducted of 1,540 randomly selected households in high, medium, and low impact areas (defined using police and community reports), and a survey of 162 nurses (75 per cent response rate) working in clinic and maternity services in Cape Town's townships was undertaken. Methodological problems were encountered in relation to sampling, interviewer allocation to areas, and access to routinely available information. Nevertheless, a consistent picture emerged from the studies that: demonstrated the impact of political violence on attendance at routine health service facilities (for hypertension, tuberculosis, immunizations, antenatal and postnatal services); highlighted the disruptions caused to basic services in high impact areas (water, street lighting, sanitation and transport); documented the problems experienced by nurses in performing their usual services and by patients obtaining access to their services; showed that high impact areas had three times higher rates of gunshot wounds than low impact areas during the period.

    Full Text Available Increased fertility rates in HIV-infected women receiving antiretroviral therapy (ART have been attributed to improved immunological function; it is unknown to what extent the rise in pregnancy rates is due to unintended pregnancies.Non-pregnant women ages 18-35 from four public-sector ART clinics in Johannesburg, South Africa, were enrolled into a prospective cohort and followed from August 2009-March 2011. Fertility intentions, contraception and pregnancy status were measured longitudinally at participants' routine ART clinic visits.Of the 850 women enrolled, 822 (97% had at least one follow-up visit and contributed 745.2 person-years (PY at-risk for incident pregnancy. Overall, 170 pregnancies were detected in 161 women (incidence rate [IR]: 21.6/100 PY [95% confidence interval (CI: 18.5-25.2]. Of the 170 pregnancies, 105 (62% were unplanned. Unmet need for contraception was 50% higher in women initiating ART in the past year as compared to women on ART>1 year (prevalence ratio 1.5 [95% CI: 1.1-2.0]; by two years post-ART initiation, nearly one quarter of women had at least one unplanned pregnancy. Cumulative incidence of pregnancy was equally high among recent ART initiators and ART experienced participants: 23.9% [95% CI: 16.4-34.1], 15.9% [12.0-20.8], and 21.0% [16.8-26.1] for women on ART 0-1 yr, >1 yr-2 yrs, and >2 yrs respectively (log-rank, p = 0.54. Eight hormonal contraceptive failures were detected [IR: 4.4 [95% CI: 2.2-8.9], 7/8 among women using injectable methods. Overall 47% (80/170 of pregnancies were not carried to term.Rates of unintended pregnancies among women on ART are high, including women recently initiating ART with lower CD4 counts and higher viral loads. A substantial burden of pregnancy loss was observed. Integration of contraceptive services and counselling into ART care is necessary to reduce maternal and child health risks related to mistimed and unwanted pregnancies.

    Full Text Available Objective: The presence of multiple global health aid organizations in donor recipient countries at any point in time has led to arguments for and against aid coordination and aid pluralism. Little data, however, exist to empirically demonstrate the relationship between donor presence and longitudinal disease outcomes in donor-recipient countries. We examined the association between global health donor presence and changes in HIV/AIDS prevalence in 14 developing countries: 12 in Africa (Ethiopia, Kenya, Tanzania, Malawi, Zimbabwe, Mozambique, Rwanda, South Africa, Uganda, Zambia, Burkina Faso and Mali and compared them with two developing countries in Asia (India and Vietnam. Methods: To conduct our analyses, we conceptualized a framework for examining global health donor presence and disease outcomes. Donor presence data were derived from Mapping the Donor Landscape in Global Health: HIV/AIDS, a report published by the Kaiser Family Foundation, Washington, DC, USA. HIV/AIDS prevalence data were obtained and analyzed from the World Health Statistics and the Demographic and Health Surveys. Percent changes in national HIV/AIDS prevalence between 2009 and 2011 in the 14 developing countries were computed and correlation coefficients between donor presence and prevalence changes were calculated. Results: Between 2009 and 2011, HIV/AIDS prevalence decreased in all but one of the 14 developing countries with the presence of 21 or more global health donors. There was about 40% overall reduction in HIV/AIDS prevalence across the 14 countries in our analyses. South Africa recorded the most reduction in HIV/AIDS prevalence (-6.7% followed by Zambia (-6.3, %, and Mozambique (-5.7%. Ethiopia was the only country without a reduction in HIV/AIDS prevalence (+0.1%. A correlation coefficient of 0.43 implied greater reductions in HIV/AIDS prevalence associated with increased donor presence. Conclusions and Public Health Implications: Our study shows a

    Full Text Available If multidisciplinarity is necessary, first, for studying the widest possible set of communication phenomena (organizational, in groups, interpersonal, media, computer-mediated communication... and, secondly, for grasping the complexity of the different moments of the same phenomenon of communication (production, content, reception, circulation ..., methodological pluralism is also important. However, French research in communication sciences leaves in the shade a number of phenomena and moments of communication that could be better understood thanks to the experimental method. We will underline that the epistemological issues related to rational use of the experimental method in communication sciences are not negligible: it allows the study of objects that cannot be investigated with other methods and offers the opportunity to build knowledge by the refutation of hypotheses and theoretical propositions. We will clarify some epistemological misunderstandings concerning this method. First, it is actually a method of studying complex systems and communication processes. Secondly, its use is not incompatible with constructivism.

    Rachel Jewkes

    Full Text Available OBJECTIVE: To describe the prevalence and patterns of rape perpetration in a randomly selected sample of men from the general adult population, to explore factors associated with rape and to describe how men explained their acts of rape. DESIGN: Cross-sectional household study with a two- stage randomly selected sample of men. METHODS: 1737 South African men aged 18-49 completed a questionnaire administered using an Audio-enhanced Personal Digital Assistant. Multivariable logistic regression models were built to identify factors associated with rape perpetration. RESULTS: In all 27.6% (466/1686 of men had raped a woman, whether an intimate partner, stranger or acquaintance, and whether perpetrated alone or with accomplices, and 4.7% had raped in the last 12 months. First rapes for 75% were perpetrated before age 20, and 53.9% (251 of those raping, did so on multiple occasions. The logistic regression model showed that having raped was associated with greater adversity in childhood, having been raped by a man and higher maternal education. It was associated with less equitable views on gender relations, having had more partners, and many more gender inequitable practices including transactional sex and physical partner violence. Also drug use, gang membership and a higher score on the dimensions of psychopathic personality, namely blame externalisation and Machiavellian egocentricity. Asked about why they did it, the most common motivations stemmed from ideas of sexual entitlement. CONCLUSIONS: Perpetration of rape is so prevalent that population-based measures of prevention are essential to complement criminal justice system responses. Our findings show the importance of measures to build gender equity and change dominant ideas of masculinity and gender relations as part of rape prevention. Reducing men's exposure to trauma in childhood is also critically important.

    Full Text Available In recent times many Nigerians have been singled out when it comes to criminal activities and xenophobic attacks in South Africa, which leads to disruption of the hitherto cordial relationship between South African host communities and Nigerian migrants. Nevertheless, the rate of Nigerians migrating to South Africa keeps soaring. Studies of migration between Nigeria and South Africa, have been scanty, often limited to the study of traditional economic disparity between the two countries with less emphasis on the social-cultural challenges facing Nigerian migrants in the host communities. This paper thus examined the socio-economic and cultural challenges facing Nigerian migrants in selected communities in Johannesburg, South Africa. Data for the study were collected through in-depth interviews and focus group discussions with Nigerian migrants in Hillbrow, Braamfontein and Alexandra suburbs in Johannesburg, South Africa.

    Annual mortality events in Nile crocodiles (Crocodylus niloticus) in the Olifants River Gorge in Kruger National Park, South Africa, were experienced between 2008 and 2012, during which at least 216 crocodiles died. Live crocodiles were lethargic. Necropsy examination of 56 affected crocodiles showed dark yellow-brown firm nodules in both somatic fat and the abdominal fat body. In all of the 11 crocodiles submitted for histology, degenerative, necrotic, and inflammatory changes supported a diagnosis of steatitis in both fat types. Crocodiles are apex predators in this anthropogenically changed aquatic ecosystem that is used by humans upstream and downstream from the park for domestic, agricultural, fishing, and recreational purposes. This pathologic review of pansteatitis in crocodiles in the Olifants River system was part of a broad multidisciplinary research program. To date, no definitive causative agent has been identified. Epidemiologic evidence suggests that this event may have been a one-time event with long-standing repercussions on the health of the crocodiles. Pathologic findings are rarely documented in wild crocodilians. This study also reports on other conditions, including the presence of coccidian oocysts, capillarid and filaroid nematodes, digenetic trematodes, and pentastomes.

    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

    In the context of successful antiretroviral therapy (ART) for the management of HIV infection, the harmful effects of stress remain a significant threat. Stress may increase viral replication, suppress immune response, and impede adherence to ART. Stressful living conditions of poverty, facing a chronic life-threatening illness and stigma all exacerbate chronic stress in HIV-affected populations. Stress-reduction interventions are urgently needed for the comprehensive care of people living with HIV. Mindfulness-based stress reduction (MBSR) is one approach that has shown promise as an intervention for patients facing other medical conditions for reducing disease progression, psychological distress and maladaptive behaviours. In this systematic review, we identified 11 studies that have examined MBSR as an intervention for HIV-positive populations. Of the studies, six were randomised designs, one was a quasi-experimental design, and the remaining four were pre- and post-test designs. The preliminary outcomes support MBSR to decrease emotional distress with mixed evidence for impact on disease progression. Effect sizes were generally small to moderate in magnitude. The early findings from this emerging literature must be considered preliminary and support moving forward with more rigorous controlled trials, evaluated with objective assessments in longer-term follow-ups to determine the efficacy of MBSR for people living with HIV.

  11. Feasibility, yield, and cost of active tuberculosis case finding linked to a mobile HIV service in Cape Town, South Africa: a cross-sectional study.

    Katharina Kranzer

    Full Text Available BACKGROUND: The World Health Organization is currently developing guidelines on screening for tuberculosis disease to inform national screening strategies. This process is complicated by significant gaps in knowledge regarding mass screening. This study aimed to assess feasibility, uptake, yield, treatment outcomes, and costs of adding an active tuberculosis case-finding program to an existing mobile HIV testing service. METHODS AND FINDINGS: The study was conducted at a mobile HIV testing service operating in deprived communities in Cape Town, South Africa. All HIV-negative individuals with symptoms suggestive of tuberculosis, and all HIV-positive individuals regardless of symptoms were eligible for participation and referred for sputum induction. Samples were examined by microscopy and culture. Active tuberculosis case finding was conducted on 181 days at 58 different sites. Of the 6,309 adults who accessed the mobile clinic, 1,385 were eligible and 1,130 (81.6% were enrolled. The prevalence of smear-positive tuberculosis was 2.2% (95% CI 1.1-4.0, 3.3% (95% CI 1.4-6.4, and 0.4% (95% CI 1.4 015-6.4 in HIV-negative individuals, individuals newly diagnosed with HIV, and known HIV, respectively. The corresponding prevalence of culture-positive tuberculosis was 5.3% (95% CI 3.5-7.7, 7.4% (95% CI 4.5-11.5, 4.3% (95% CI 2.3-7.4, respectively. Of the 56 new tuberculosis cases detected, 42 started tuberculosis treatment and 34 (81.0% completed treatment. The cost of the intervention was US$1,117 per tuberculosis case detected and US$2,458 per tuberculosis case cured. The generalisability of the study is limited to similar settings with comparable levels of deprivation and TB and HIV prevalence. CONCLUSIONS: Mobile active tuberculosis case finding in deprived populations with a high burden of HIV and tuberculosis is feasible, has a high uptake, yield, and treatment success. Further work is now required to examine cost-effectiveness and affordability and

    Over the past decade, our understanding of the role of stress in serious mental illness has become more sophisticated. In this paper, we revisit the neural diathesis-stress model of schizophrenia that was initially proposed in 1997 and updated in 2008. In light of cumulative research findings, we must now encompass evidence on the premorbid periods of psychosis, and our more nuanced understanding of hypothalamic-pituitary-adrenal (HPA) axis function and its association with neurodevelopmental, epigenetic, neurotransmitter, and inflammatory processes, as well as brain structure and function. Giving consideration to the methodological complexities that have become more apparent as research in this area has burgeoned, the various indices of HPA axis function, and the different stages of illness, we review relevant research published since the 2008 update of the model. We conclude by proposing an extended neural diathesis-stress model that addresses the broader neurobiological context of stress psychobiology in psychosis progression. Implications of this model for best practice, with regards to both future research and treatment strategies, are discussed.

    Full Text Available Abstract Background Study-based global health interventions, especially those that are conducted on an international or multi-site basis, frequently require site-specific adaptations in order to (1 respond to socio-cultural differences in risk determinants, (2 to make interventions more relevant to target population needs, and (3 in recognition of ‘global health diplomacy' issues. We report on the adaptations development, approval and implementation process from the Project Accept voluntary counseling and testing, community mobilization and post-test support services intervention. Methods We reviewed all relevant documentation collected during the study intervention period (e.g. monthly progress reports; bi-annual steering committee presentations and conducted a series of semi-structured interviews with project directors and between 12 and 23 field staff at each study site in South Africa, Zimbabwe, Thailand and Tanzania during 2009. Respondents were asked to describe (1 the adaptations development and approval process and (2 the most successful site-specific adaptations from the perspective of facilitating intervention implementation. Results Across sites, proposed adaptations were identified by field staff and submitted to project directors for review on a formally planned basis. The cross-site intervention sub-committee then ensured fidelity to the study protocol before approval. Successfully-implemented adaptations included: intervention delivery adaptations (e.g. development of tailored counseling messages for immigrant labour groups in South Africa political, environmental and infrastructural adaptations (e.g. use of local community centers as VCT venues in Zimbabwe; religious adaptations (e.g. dividing clients by gender in Muslim areas of Tanzania; economic adaptations (e.g. co-provision of income generating skills classes in Zimbabwe; epidemiological adaptations (e.g. provision of ‘youth-friendly’ services in South Africa, Zimbabwe

    Background: This paper presents the methodology and early findings of the fifth survey of a school-based surveillance program in Iran. Methods: This nationwide study was conducted in 2015 as the fifth survey of a surveillance program entitled “Childhood and Adolescence Surveillance and PreventIon of Adult Non- communicable disease” (CASPIAN-V) study. The protocol was mainly based on the World Health Organization-Global School student Health Survey. We studied 14400 students, aged 7-18 years, and their parents living in 30 provinces in Iran. Fasting blood was obtained from a sub-sample of 4200 randomly selected students. Results: The participation rate for the whole study and for blood sampling were 99% and 91.5%, respectively. The mean (SD) age of participants was 12.3 (3.2) years, consisting of 49.4% girls and 71.4% urban residents. Overall, 16.1% were underweight (17.4% of boys and 14.8% of girls), and 20.8% had excess weight consisting of 9.4% (8.7% of boys and 10.2% of girls) of overweight and 11.4% (12.5% of boys and 10.3% of girls) of obesity. Abdominal obesity was documented in 21.1% of students (21.6% of boys and 20.5% of girls). Low HDL-C was the most prevalent abnormality of the lipid profile (29.5%) followed by high serum triglycerides (27.7%). Of students, 59.9% consumed whole wheat bread; and 57% reported that they never or rarely added salt to table. The reported daily consumption of fresh fruits, vegetables, and milk was about 60%, 32% and 40%, respectively. 13.7% of participants had at least 30-min daily leisure-time physical activity. Conclusions: The current findings provide an overview of the current health status and lifestyle habits of children and adolescents. This surveillance program would help planning preventive programs at individual and community levels. PMID:28217266

    Full Text Available BACKGROUND: The majority of patients with multidrug-resistant tuberculosis (MDR-TB in South Africa are co-infected with HIV, but the radiographic features of MDR-TB and their relationship with time to sputum culture conversion in the antiretroviral therapy era have not been described. METHODS: We reviewed baseline chest radiographs for 56 patients with MDR-TB from a rural area of South Africa. We analyzed the association of cavities, consolidation, pleural effusion and hilar lymphadenopathy with time to sputum culture conversion, adjusting for HIV status, baseline sputum smear and CD4 count. RESULTS: Of the 56 subjects, 49 (88% were HIV-positive, with a median CD4 count of 136 cells/mm(3 (IQR 65-249. Thirty-two (57% patients were sputum smear positive. Twenty-two (39% patients had a cavity and 37 (66% patients had consolidations. Cavitary disease and consolidations were each associated with longer time to culture conversion on bivariate analysis but not after adjusting for sputum smear status (aORs 1.79 [0.94-3.42] and 1.09 [0.67-1.78], respectively. Positive baseline sputum smear remained independently associated with longer time to conversion (aOR 3.45 [1.39-8.59]. We found no association between pleural effusion or hilar lymphadenopathy and time to conversion. Seventy-nine percent of patients were cured at the end of treatment. CONCLUSIONS: Despite high rates of HIV co-infection and advanced immunodeficiency, the majority of patients had severe pathology on baseline chest radiograph. Nevertheless, culture conversion rates were high and treatment outcomes were favorable. Cavitation and consolidation do not appear to have an independent association with time to culture conversion beyond that of baseline sputum smear status.

    A. J. Vogel

    2010-12-01

    Full Text Available Purpose: Owing to a shortage of South African research focusing on international strategic alliances, this study aimed to determine whether the advantages and pitfalls of international strategic alliances referred to in international business publications are also applicable to South African international strategic alliances. Design/Methodology/Approach: This was a formal, empirical study that targeted the 163 South African enterprises which were members of the South African-Angolan Chamber of Commerce in 2005 and 2006. Findings: The results identified joint ventures as the most prominent mode of entry when expanding into developing countries and, with few exceptions, the findings support the advantages and pitfalls of international strategic alliances identified in other international publications. Value of the research: A great deal of international management research over the years has been focused on the importance of strategic alliances as a mode of entry, as well as on the pitfalls experienced by alliance partners, particularly in developed countries. However, the lack of such research in Africa in general and South Africa in particular means that South African enterprises must base their entry mode selection on non-South African research findings, and although this sample size was small, the lack of other Africa-specific research makes this research significant. Implications: With South Africa being the largest source of FDI into the rest of Africa, the findings of this paper show that South African enterprises can attain the advantages associated with international strategic alliances when using this mode of entry into Africa. In terms of pitfalls, the findings highlight the need for multinational enterprises to pay specific attention to the role of governments when forming strategic alliances.

    Full Text Available Background and objective: The achievement of universal health coverage (UHC in emerging economies is a high priority within the global community. This timely study uses standardized national population data collected from adults aged 50 and older in China, Ghana, India, Mexico, the Russian Federation, and South Africa. The objective is to describe health care utilization and measure association between inpatient and outpatient service use and patient characteristics in these six low- and middle-income countries. Design: Secondary analysis of data from the World Health Organization's Study on global AGEing and adult health Wave 1 was undertaken. Country samples are compared by socio-demographic characteristics, type of health care, and reasons for use. Logistic regressions describe association between socio-demographic and health factors and inpatient and outpatient service use. Results: In the pooled multi-country sample of over 26,000 adults aged 50-plus, who reported getting health care the last time it was needed, almost 80% of men and women received inpatient or outpatient care, or both. Roughly 30% of men and women in the Russian Federation used inpatient services in the previous 3 years and 90% of men and women in India used outpatient services in the past year. In China, public hospitals were the most frequently used service type for 52% of men and 51% of women. Multivariable regression showed that, compared with men, women were less likely to use inpatient services and more likely to use outpatient services. Respondents with two or more chronic conditions were almost three times as likely to use inpatient services and twice as likely to use outpatient services compared with respondents with no reported chronic conditions. Conclusions: This study provides a basis for further investigation of country-specific responses to UHC.

    ABSTRACT Background: The 2014 outbreak of Ebola virus disease (EVD) in West Africa was the largest ever recorded. Starting in September 2014, International Medical Corps (IMC) managed 5 Ebola treatment units (ETUs) in Liberia and Sierra Leone, which cumulatively cared for about 2,500 patients. We conducted a retrospective cohort study of patient data collected at the 5 ETUs over 1 year of operations. Methods: To collect clinical and epidemiological data from the patient care areas, each chart was either manually copied across the fence between the high-risk zone and low-risk zone, imaged across the fence, or imaged in the high-risk zone. Each ETU’s data were entered into a separate electronic database, and these were later combined into a single relational database. Lot quality assurance sampling was used to ensure data quality, with reentry of data with high error rates from imaged records. Results: The IMC database contains records on 2,768 patient presentations, including 2,351 patient admissions with full follow-up data. Of the patients admitted, 470 (20.0%) tested positive for EVD, with an overall case fatality ratio (CFR) of 57.0% for EVD-positive patients and 8.1% for EVD-negative patients. Although more men were admitted than women (53.4% vs. 46.6%), a larger proportion of women were diagnosed EVD positive (25.6% vs. 15.2%). Diarrhea, red eyes, contact with an ill person, and funeral attendance were significantly more common in patients with EVD than in those with other diagnoses. Among EVD-positive patients, age was a significant predictor of mortality: the highest CFRs were among children under 5 (89.1%) and adults over 55 (71.4%). Discussion: While several prior reports have documented the experiences of individual ETUs, this study is the first to present data from multiple ETUs across 2 countries run by the same organization with similar clinical protocols. Our experience demonstrates that even in austere settings under difficult conditions, it is

    Literature from sub-Saharan Africa and elsewhere supports a global association between alcohol and HIV risk. However, more rigorous studies using multiple event-level methods find mixed support for this association, suggesting the importance of examining potential moderators of this relationship. The present study explores the assumptions of alcohol expectancy theory and alcohol myopia theory as possible moderators that help elucidate the circumstances under which alcohol may affect individuals' ability to use a condom. Participants were 82 individuals (58 women, 24 men) living with HIV who completed daily phone interviews for 42 days which assessed daily sexual behavior and alcohol consumption. Logistic generalized estimating equation models were used to examine the potential moderating effects of inhibition conflict and sex-related alcohol outcome expectancies. The data provided some support for both theories and in some cases the moderation effects were stronger when both partners consumed alcohol.

    Full Text Available An epidemiological study was carried out in 2004-2005 at the anti-tuberculosis centre of Divo (Ivory Coast to collect sera from patients who consulted for tuberculosis suspicion and to estimate the seroprevalence of human paragonimosis in the context of a systematic screening. No Paragonimus egg was found in the stools and/or sputa of the 167 persons investigated. In contrast, 41 sera were ascertained with antibodies against Paragonimus africanus using ELISA testing. As the optical density (OD values related to seropositive findings were found under 0.6 (the minimal OD to detect an active paragonimosis, the above antibody titres might originate from patients in chronic or in convalescent stages, or might result of cross reactions with trematodes. Concomitantly, dissection of local crabs (Callinectes marginatus demonstrated the presence of Paragonimus metacercariae in six out of 34 examined. The parasite burdens in crabs ranged from two to 35 cysts with a mean diameter of 302 μm. In Ivory Coast, the locality of Divo must be considered an at-risk zone in reason of the presence of anti-Paragonimus antibodies in several human sera and the presence of infected crabs at the local market.

    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.

    2013-11-01

    Gender is a critical component of HIV and sexual risk interventions. Examining the range, effectiveness and methodological rigor of studies that include a gender based component can inform current interventions and future directions for intervention research. This review investigated gender informed intervention studies conducted in sub-Saharan Africa that measured an outcome related to HIV. We reviewed 311 articles, 41 of which met our inclusion criteria, resulting in 11 articles that described eight different studies used in the analyses. The findings demonstrated wide variations in the types of interventions from low intensity educational content to multi-component interventions. Study outcomes were categorized into biological outcomes, HIV risk, behavioral, violence and risk reduction. Most interventions showed positive effects, and although research methodologies varied considerably, longer interventions appeared to be more effective. More research, however, is needed to build the evidence base for effectiveness of gender-based programs in reducing HIV infections in sub-Saharan Africa.

    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.

  4. Guidelines for the marketing of independent schools in South Africa

    2015-02-01

    Full Text Available Objective: The primary objective of the study is to recommend marketing guidelines for independent primary schools, with the focus on product and people in the marketing mix. This objective was achieved by identifying choice factors influencing parents’ selection of independent primary schools, identifying the most important choice factors and demographic differences regarding the importance parents attached to these factors.Problem investigated: Some independent schools in South Africa find it difficult to market themselves effectively as a result of a lack of information pertaining to the choice factors identified by parents when selecting independent primary schools. A comprehensive set of choice factors will provide a more accurate picture of the criteria parents perceive as important in independent school selection.Methodology: The methodological approach followed was exploratory and quantitative in nature. The sample consisted of 669 respondents from 30 independent schools in Gauteng in South Africa. A structured questionnaire, with a five-point Likert scale, was fielded to gather the data. The descriptive and factor analysis approaches were used to analyse the results.Findings and implications: The main finding is that a total of 29 different choice factors were identified that parents perceive as important when selecting an independent primary school. The most important factor for parents when making a choice is the small size of the classes, followed by the religious ethos of the school as well as qualified and committed educators. This indicates that parents have a comprehensive set of choice factors and implies that a better understanding of these factors by independent schools may assist them to focus their marketing efforts more optimally in order to attract new learners.Originality and value of the research: Very little research exists with specific reference to independent school marketing in South Africa

  5. The onset and cessation of seasonal rainfall over Africa

    2016-10-01

    Variation in the seasonal cycle of African rainfall is of key importance for agriculture. Here an objective method of determining the timing of onset and cessation is, for the first time, extended to the whole of Africa. The method is applied to five observational data sets and the ERA-Interim reanalysis. Compatibility with known physical drivers of African rainfall, consistency with indigenous methods, and generally strong agreement between satellite-based rainfall data sets confirm that the method is capturing the correct seasonal progression of African rainfall. The biannual rainfall regime is correctly identified over the coastal region of Ghana and the Ivory Coast. However, the ERA-Interim reanalysis exhibits timing biases over areas with two rainy seasons, and both ERA-Interim and the ARCv2 observational data set exhibit some inconsistent deviations over West Africa. The method can be used to analyze both seasonal-interannual variability and long-term change. Over East Africa, we find that failure of the rains and subsequent humanitarian disaster is associated with shorter as well as weaker rainy seasons, e.g., on average the long rains were 11 days shorter in 2011. Cessation of the short rains over this region is 7 days later in El Niño and 5 days earlier in La Niña years with only a small change in onset date. The methodology described in this paper is applicable to multiple data sets and to large regions, including those that experience multiple rainy seasons. As such, it provides a means for investigating variability and change in the seasonal cycle over the whole of Africa.

    2008-12-01

    Full Text Available Purpose/objectives: The aim of this article is to look at the experiences, problems and the potential contribution of employment creation programmes in alleviating the unemployment problem in other African countries through the construction of public infrastructure through the use of labour-intensive methods. The article then describes the problems and experiences that have been encountered in South Africa in relation to employment creation through the construction of public infrastructure.Problem investigated: In South Africa the levels of unemployment and poverty are extremely high and unemployment is one of South Africa's most pressing problems. At the same time there is a lack of capacity and skills at institutional, community and individual levels. Labour-intensive programmes generate more direct and indirect local employment opportunities and income by using locally available inputs (materials, simple tools and local labour and thus creating a greater demand for local products and services than do high-technology programmes reliant on imported technology and equipment. Design/Methodology/Approach: Drawing on research on labour-intensive, public works programmes and projects, the paper is mainly a literature review. From a theoretical perspective supported by experience elsewhere in Africa, there are reasons for considering that properly formulated employment creation programmes based on the use of labour-intensive methods could be established to construct and maintain the required physical infrastructure, thus creating employment, skills and institutional capacities. The article closes with some recommendations for the future programmes success.Findings/Implications: The article attributes the failure of projects and programmes in South Africa to different factors which must be avoided in future in order for projects and programmes to be successful in South Africa. Investment in infrastructure has a huge potential to redress the high

    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.

  17. Multispacer sequence typing relapsing fever Borreliae in Africa.

    Directory of Open Access Journals (Sweden)

    Haitham Elbir

    Full Text Available BACKGROUND: In Africa, relapsing fevers are neglected arthropod-borne infections caused by closely related Borrelia species. They cause mild to deadly undifferentiated fever particularly severe in pregnant women. Lack of a tool to genotype these Borrelia organisms limits knowledge regarding their reservoirs and their epidemiology. METHODOLOGY/PRINCIPAL FINDINGS: Genome sequence analysis of Borrelia crocidurae, Borrelia duttonii and Borrelia recurrentis yielded 5 intergenic spacers scattered between 10 chromosomal genes that were incorporated into a multispacer sequence typing (MST approach. Sequencing these spacers directly from human blood specimens previously found to be infected by B. recurrentis (30 specimens, B. duttonii (17 specimens and B. crocidurae (13 specimens resolved these 60 strains and the 3 type strains into 13 species-specific spacer types in the presence of negative controls. B. crocidurae comprised of 8 spacer types, B. duttonii of 3 spacer types and B. recurrentis of 2 spacer types. CONCLUSIONS/SIGNIFICANCE: Phylogenetic analyses of MST data suggested that B. duttonii, B. crocidurae and B. recurrentis are variants of a unique ancestral Borrelia species. MST proved to be a suitable approach for identifying and genotyping relapsing fever borreliae in Africa. It could be applied to both vectors and clinical specimens.

    Various methods have been developed independently to study the multifractality of measures in many different contexts. Although they all convey the same intuitive idea of giving a "dimension" to sets where a quantity scales similarly within a space, they are not necessarily equivalent on a more rigorous level. This review article aims at unifying the multifractal methodology by presenting the multifractal theoretical framework and principal practical methods, namely the moment method, the histogram method, multifractal detrended fluctuation analysis (MDFA) and modulus maxima wavelet transform (MMWT), with a comparative and interpretative eye.

    2002-02-01

    Full Text Available Background and Purpose: Research interest has increased in physiotherapy in the past two decades. During this period, the physiotherapy department at the Medical University of Southern Africa(MEDUNSA started its degree programme. The first undergraduateresearch projects (UGRP were produced in 1985. The purpose of this study was to analyze the UGRPs conducted between 1985 and 1999 in terms of methodological trends (qualitative versus quantitative and subject content.Methods: A retrospective analysis of the 114 UGRPs carried out in the department was conducted. The projects were read and analyzed according to methodology, research context and topic categories. The 15-year period was analyzed in three 5-year phases (1985 - 1989; 1990 - 1994 and 1995 - 1999, using descriptive statistics. Results: There was a gradual increase in the number of UGRPs during the study period in keeping with the increase in student numbers, with the last five years recording the highest number of projects. An interesting finding was a decline in experimental and clinical research, which was lowest in the last five years. Conclusion: The findings are paradoxical, given the need for experimental research to validate current clinical  practice. Non-experimental qualitative research is however important in the view of the national health plan.  A balance between qualitative and quantitative research is therefore important and must be emphasized in student training. Student research projects need to be maximally utilized to improve departmental research output.

  6. The epistemology of AIDS in South Africa: lessons from three scenario projects.

    Science.gov (United States)

    Swart, Charl; Fourie, Pieter

    2015-01-01

    This article reviews the methodology of future scenario-building in the context of HIV and AIDS in Africa. It considers three scenario studies conducted in the past decade: UNAIDS (2005), Metropolitan Holdings (2006) and the AIDS Governance scenarios (2015). The article is a critical reflection of Future Studies epistemology which claims to contribute a unique heuristic niche in the study of AIDS. The article offers several methodological insights: (1) despite claims to the contrary, scenario methodology remains profoundly influenced by existing political and research agenda; instead of denying these, scenarists should acknowledge this; (2) the utility of scenario studies is strongly influenced by their unit of analysis and their time frame, which determine their applicability and therefore their policy relevance; and (3) scenario planners should guard against perpetuating the myth that this methodology is a crystal ball into the future because they are powerful tools for strategic planning about the present, rather than the distant future. In addition to these methodological insights, the article finds that future scenario studies are useful in identifying significant discursive and policy shifts in the AIDS response.

    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.

    2016-04-01

    Using data from four sites in three African countries, this community randomized study examined the association between childhood sexual and/or physical abuse (CSA and/or CPA) and HIV disclosure, HIV-related stigma, stress, and social support among adults with and without a history of abuse. A history of abuse among men was associated with higher levels of adult-reported stress and HIV-related stigma, and with significantly lower rates of HIV test result disclosure to current partners. Women with a history of CSA and/or CPA had significantly higher perceived stigma, discrimination and stress. Although childhood abuse was significantly associated with adult stress and stigmatization, participants with histories of CSA and/or CPA also reported significantly higher perceived social support compared to people without such experiences. These findings may reflect support received in response to disclosure of CSA or CPA or emotional ambivalence in relationships that have been found to be associated with child abuse. We conclude that it is critical for HIV prevention interventions to advocate for the primary prevention of child abuse, for early identification of adolescents and adults who report experiencing childhood abuse, and to address stigma and stress-related attitudinal, behavioral and relationship difficulties experiences as an aftermath of early abuse that increase their risk of HIV.

  12. The role of culture in effective HIV/AIDS communication by theatre in South Africa.

    Uwah, Chijioke

    2013-01-01

    The need to effectively communicate HIV/AIDS messages in South Africa, given the high prevalence of the pandemic, cannot be overemphasised. Communication scholars have long emphasised the need to recognise adherence to cultural norms of target communities as catalyst for effective HIV/AIDS communication. Unfortunately this call has not been totally heeded by the designers of HIV/AIDS communication instruments. In the case of theatre, research has shown that in South Africa, theatre groups have gone into communities with pre-packaged plays without due cognisance of the cultural norms and beliefs of the target population. This research was conducted in KwaZulu-Natal (the province with the highest prevalence rate of HIV/AIDS infection in South Africa). Using a qualitative research methodology this paper investigated the inclusion/non-inclusion of the cultural norms of the target population in the design of the dramatic performance by the theatre group in its HIV/AIDS campaigns. The findings indicate that while the group did try to incorporate aspects of the cultural norms of the target population, it did so at a level that failed to effectively communicate the HIV/AIDS message to its audiences. This paper therefore seeks to show through empirical evidence that the non-inclusion of cultural norms and values of the target population has acted as a stumbling block in the effective communication of HIV/AIDS messages by theatre groups in the country.

    2007-10-23

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

    Deans, Rachel; Wade, Shawna

    2011-01-01

    Growing demand from clients waiting to access vital services in a healthcare sector under economic constraint, coupled with the pressure for ongoing improvement within a multi-faceted organization, can have a significant impact on the front-line staff, who are essential to the successful implementation of any quality improvement initiative. The Lean methodology is a management system for continuous improvement based on the Toyota Production System; it focuses on two main themes: respect for people and the elimination of waste or non-value-added activities. Within the Lean process, value-added is used to describe any activity that contributes directly to satisfying the needs of the client, and non-value-added refers to any activity that takes time, space or resources but does not contribute directly to satisfying client needs. Through the revision of existing models of service delivery, the authors' organization has made an impact on increasing access to care and has supported successful engagement of staff in the process, while ensuring that the focus remains on the central needs of clients and families accessing services. While the performance metrics continue to exhibit respectable results for this strategic priority, further gains are expected over the next 18-24 months.

  16. Soft Systems Methodology

    Science.gov (United States)

    Checkland, Peter; Poulter, John

    Soft systems methodology (SSM) is an approach for tackling problematical, messy situations of all kinds. It is an action-oriented process of inquiry into problematic situations in which users learn their way from finding out about the situation, to taking action to improve it. The learning emerges via an organised process in which the situation is explored using a set of models of purposeful action (each built to encapsulate a single worldview) as intellectual devices, or tools, to inform and structure discussion about a situation and how it might be improved. This paper, written by the original developer Peter Checkland and practitioner John Poulter, gives a clear and concise account of the approach that covers SSM's specific techniques, the learning cycle process of the methodology and the craft skills which practitioners develop. This concise but theoretically robust account nevertheless includes the fundamental concepts, techniques, core tenets described through a wide range of settings.

    Tobacco documents research has developed into a thriving academic enterprise since its inception in 1995. The technology supporting tobacco documents archiving, searching and retrieval has improved greatly since that time, and consequently tobacco documents researchers have considerably more access to resources than was the case when researchers had to travel to physical archives and/or electronically search poorly and incompletely indexed documents. The authors of the papers presented in this supplement all followed the same basic research methodology. Rather than leave the reader of the supplement to read the same discussion of methods in each individual paper, presented here is an overview of the methods all authors followed. In the individual articles that follow in this supplement, the authors present the additional methodological information specific to their topics. This brief discussion also highlights technological capabilities in the Legacy Tobacco Documents Library and updates methods for organising internal tobacco documents data and findings.

    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.

    Full Text Available Abstract Background Scoping studies are an increasingly popular approach to reviewing health research evidence. In 2005, Arksey and O'Malley published the first methodological framework for conducting scoping studies. While this framework provides an excellent foundation for scoping study methodology, further clarifying and enhancing this framework will help support the consistency with which authors undertake and report scoping studies and may encourage researchers and clinicians to engage in this process. Discussion We build upon our experiences conducting three scoping studies using the Arksey and O'Malley methodology to propose recommendations that clarify and enhance each stage of the framework. Recommendations include: clarifying and linking the purpose and research question (stage one; balancing feasibility with breadth and comprehensiveness of the scoping process (stage two; using an iterative team approach to selecting studies (stage three and extracting data (stage four; incorporating a numerical summary and qualitative thematic analysis, reporting results, and considering the implications of study findings to policy, practice, or research (stage five; and incorporating consultation with stakeholders as a required knowledge translation component of scoping study methodology (stage six. Lastly, we propose additional considerations for scoping study methodology in order to support the advancement, application and relevance of scoping studies in health research. Summary Specific recommendations to clarify and enhance this methodology are outlined for each stage of the Arksey and O'Malley framework. Continued debate and development about scoping study methodology will help to maximize the usefulness and rigor of scoping study findings within healthcare research and practice.

    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.

  8. HIV/AIDS drugs for Sub-Saharan Africa: how do brand and generic supply compare?

    Directory of Open Access Journals (Sweden)

    Colleen V Chien

    Full Text Available BACKGROUND: Significant quantities of antiretroviral drugs (ARVs to treat HIV/AIDS have been procured for Sub-Saharan Africa for the first time in their 20-year history. This presents a novel opportunity to empirically study the roles of brand and generic suppliers in providing access to ARVs. METHODOLOGY/PRINCIPAL FINDINGS: An observational study of brand and generic supply based on a dataset of 2,162 orders of AIDS drugs for Sub-Saharan Africa reported to the Global Price Reporting Mechanism at the World Health Organization from January 2004-March 2006 was performed. Generic companies supplied 63% of the drugs studied, at prices that were on average about a third of the prices charged by brand companies. 96% of the procurement was of first line drugs, which were provided mostly by generic firms, while the remaining 4%, of second line drugs, was sourced primarily from brand companies. 85% of the generic drugs in the sample were manufactured in India, where the majority of the drugs procured were ineligible for patent protection. The remaining 15% was manufactured in South Africa, mostly under voluntary licenses provided by brand companies to a single generic company. In Sub-Saharan African countries, four first line drugs in the dataset were widely patented, however no general deterrent to generic purchasing based on a patent was detected. CONCLUSIONS/SIGNIFICANCE: Generic and brand companies have played distinct roles in increasing the availability of ARVs in Sub-Saharan Africa. Generic companies provided most of the drugs studied, at prices below those charged by brand companies, and until now, almost exclusively supplied several fixed-dose combination drugs. Brand companies have supplied almost all second line drugs, signed voluntary licenses with generic companies, and are not strictly enforcing patents in certain countries. Further investigation into how price reductions in second line drugs can be achieved and the cheapest drugs can

    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.

    2003-01-01

    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.

    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 ...

    products. A contract has been competitively awarded to the Global Approval Program for Photovoltaics (PV GAP) under the Lighting Africa Program to select and test ten solar lantern product models. Lantern selection will be determined based on a number of criteria, among them, the ability to provide a daily duty cycle of at least 3 hours of light, the number of days of autonomy of battery, the volume of sales (especially in Africa), and whether or not the manufacturing facility is ISO 9000 certified. Those that are confirmed as meeting the specifications may be eligible to receive a PVGAP quality seal. The work is being carried out in partnership with the Photovoltaic and Wind Quality Test Center in Beijing, China and TUV Rhineland in Koeln, Germany. As off-grid LED-based stand-alone lighting products is in a nascent stage of development compared to CFL-based lanterns, Lighting Africa will support the development of a 'Quality Screening' approach to selecting LED lighting, in order not to delay consumers benefiting from such advances. The screening methodology could be used by procurement agencies to qualify LED lighting products for bulk or programmatic procurements. The main elements of this work comprises of developing a procurement specification and test procedure for undertaking a 'quick' quality/usability screening to be used for procuring LED lights and to test up to 30 LED-based lights to screen products that meet the requirement. The second strategy is intended to meet a longer-term need associated with creating a self-sustaining product quality assurance program that will effectively protect the African consumer, prevent significant market spoiling, adapt with expected technological advancements over the long-term--in other words, give consumers the ability to detect quality products and the information needed to find products that meet their specific needs from among the myriad of lighting products that become available commercially.

    Africa's population has grown extremely rapidly over the last fifty years from 289 million inhabitants in 1961 to more than 1 billion today. This is a growth rate of 350% in just half a century and the number of urban residents has increased even more quickly: from 65 million in 1960 to 460 million

    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.

  7. Postmodernism as a Social Science Methodology: Comments on Haugerud’s Representation of Kenya

    Full Text Available - The social scientist in Africa is presently inundated by a number of methodologies. Some of these methodologies are based on modernist theories such as: modernization, underdevelopment and dependency and the articulation of modes of production. Sometimes these modernist methodologies have emphasized empiricism that is based on either quantitative or qualitative data; at other times they have insisted on the use of theory. Over the last two decades or so an alternative methodology, namely postmodernism, has emerged to jostle with modernist methodologies for preference in usage. This paper defines this methodology and traces its origins and spread in Africa. It further outlines its forms then comments its usage by Angelique Haugerud in her book, The Culture of Politics in Modern Kenya (Haugerud, 1995. It is hoped that this paper will contribute more fruitfully to the debate on postmodernism than has resulted from other debates that are not based on analyses about the use of this methodology

    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

    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

    products. A contract has been competitively awarded to the Global Approval Program for Photovoltaics (PV GAP) under the Lighting Africa Program to select and test ten solar lantern product models. Lantern selection will be determined based on a number of criteria, among them, the ability to provide a daily duty cycle of at least 3 hours of light, the number of days of autonomy of battery, the volume of sales (especially in Africa), and whether or not the manufacturing facility is ISO 9000 certified. Those that are confirmed as meeting the specifications may be eligible to receive a PVGAP quality seal. The work is being carried out in partnership with the Photovoltaic and Wind Quality Test Center in Beijing, China and TUV Rhineland in Koeln, Germany. As off-grid LED-based stand-alone lighting products is in a nascent stage of development compared to CFL-based lanterns, Lighting Africa will support the development of a 'Quality Screening' approach to selecting LED lighting, in order not to delay consumers benefiting from such advances. The screening methodology could be used by procurement agencies to qualify LED lighting products for bulk or programmatic procurements. The main elements of this work comprises of developing a procurement specification and test procedure for undertaking a 'quick' quality/usability screening to be used for procuring LED lights and to test up to 30 LED-based lights to screen products that meet the requirement. The second strategy is intended to meet a longer-term need associated with creating a self-sustaining product quality assurance program that will effectively protect the African consumer, prevent significant market spoiling, adapt with expected technological advancements over the long-term--in other words, give consumers the ability to detect quality products and the information needed to find products that meet their specific needs from among the myriad of lighting products that become available commercially.

  14. Prospects for malaria eradication in sub-Saharan Africa.

    Directory of Open Access Journals (Sweden)

    Ricardo Aguas

    Full Text Available BACKGROUND: A characteristic of Plasmodium falciparum infections is the gradual acquisition of clinical immunity resulting from repeated exposures to the parasite. While the molecular basis of protection against clinical malaria remains unresolved, its effects on epidemiological patterns are well recognized. Accumulating epidemiological data constitute a valuable resource that must be intensively explored and interpreted as to effectively inform control planning. METHODOLOGY/PRINCIPAL FINDING: Here we apply a mathematical model to clinical data from eight endemic regions in sub-Saharan Africa. The model provides a quantitative framework within which differences in age distribution of clinical disease are assessed in terms of the parameters underlying transmission. The shorter infectious periods estimated for clinical infections induce a regime of bistability of endemic and malaria-free states in regions of mesoendemic transmission. The two epidemiological states are separated by a threshold that provides a convenient measure for intervention design. Scenarios of eradication and resurgence are simulated. CONCLUSIONS/SIGNIFICANCE: In regions that support mesoendemic transmission, intervention success depends critically on reducing prevalence below a threshold which separates endemic and malaria-free regimes.

    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.

    The second Medicines Utilization Research in Africa (MURIA) group workshop and symposium again brought researchers together from across Africa to improve their knowledge of drug utilization (DU) methodologies and exchange ideas to further progress DU research in Africa. This built on extensive activities from the first conference including workshops and multiple publications. Anti-infectives were again the principal theme for the 2016 symposium following the workshops. This included presentations regarding strategies to improve antibiotic utilization among African countries, such as point-prevalence studies, as well as potential ways to reduce self-purchasing of antibiotics. There were also presentations on antiretrovirals including renal function and the impact of policy changes. Concerns with adherence in chronic treatments as well as drug-drug interactions and their implications were also discussed. The deliberations resulted in a number of agreed activities including joint publications before the next MURIA conference in Namibia in 2017.

  3. Drought in West Africa

    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.

    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.

    The subject of this symposium is naproxen, a new drug that resulted from an investigation to find a superior anti-inflammatory agent. It was synthesized by Harrison et al. in 1970 at the Syntex Institute of Organic Chemistry and Biological Sciences. How can we chart the evolution of this or any other drug? Three steps are necessary: first, chemical studies (synthesis, analysis); second, animal pharmacology; third, human pharmacology. The last step can additionally be divided into four phases: metabolism and toxicology of the drug in normal volunteers; dose titration and initial clinical trials with sick subjects (pharmacometry); confirmatory clinical trials when the drug is accepted on the market and revaluation (familiarization trials). To discover the truth about naproxen, we must all participate actively with a critical mind, following the principles of scientific methodology. We shall find that the papers to be presented today all deal with the third step in the evaluation process--clinical pharmacology. It is quite evident that the final and most decisive test must be aimed at the most valuable target: the human being. The end product of this day's work for each of us should be the formation of an opinion based on solid scientific proofs. And let us hope that we will all enjoy fulfilling the symposium in its entire etymological meaning this evening. In vino veritas.

  11. Didactyl tracks of paravian theropods (Maniraptora from the ?Middle Jurassic of Africa.

    Directory of Open Access Journals (Sweden)

    Alexander Mudroch

    Full Text Available BACKGROUND: A new dinosaur tracksite from ?Middle Jurassic sediments of the Irhazer Group on the plains of Agadez (Rep. Niger, northwest Africa revealed extraordinarily well preserved didactyl tracks of a digitigrade bipedal trackmaker. The distinct morphology of the pes imprints indicates a theropod trackmaker from a paravian maniraptoran closely related to birds. METHODOLOGY/PRINCIPAL FINDINGS: The early age and the morphological traits of the tracks allow for description of the new ichnotaxon Paravipus didactyloides. A total of 120 tracks are assigned to 5 individual trackways. The 'medium-sized' tracks with an average footprint length of 27.5 cm and footprint width of 23.1 cm are deeply imprinted into the track bearing sandstone. CONCLUSIONS/SIGNIFICANCE: A comparison with other didactyl tracks gives new insights into the foot morphology of advanced maniraptoran theropods and contributes to knowledge of their evolutionary history. The new ichnotaxon takes an important position in the ichnological fossil record of Gondwana and the mid-Jurassic biota worldwide, because it is among the earliest known records of paravian maniraptorans and of didactyl theropod tracks from Africa.

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

  13. Q methodology in health economics.

    Baker, Rachel; Thompson, Carl; Mannion, Russell

    2006-01-01

    The recognition that health economists need to understand the meaning of data if they are to adequately understand research findings which challenge conventional economic theory has led to the growth of qualitative modes of enquiry in health economics. The use of qualitative methods of exploration and description alongside quantitative techniques gives rise to a number of epistemological, ontological and methodological challenges: difficulties in accounting for subjectivity in choices, the need for rigour and transparency in method, and problems of disciplinary acceptability to health economists. Q methodology is introduced as a means of overcoming some of these challenges. We argue that Q offers a means of exploring subjectivity, beliefs and values while retaining the transparency, rigour and mathematical underpinnings of quantitative techniques. The various stages of Q methodological enquiry are outlined alongside potential areas of application in health economics, before discussing the strengths and limitations of the approach. We conclude that Q methodology is a useful addition to economists' methodological armoury and one that merits further consideration and evaluation in the study of health services.

A validated entrepreneurial intent instrument was administered to final-year master’s business management students from a university in South Africa and a university in Poland.Methodology: A cross-sectional survey design with two samples, one from each country, was used. A previously validated questionnaire developed from Ajzen’s Theory of Planned Behaviour model was administered. The results were factor analysed and new scales extracted. These refined scales were used to assess the differences between the two countries. A total of 182 questionnaires were collected from the two universities, University of Johannesburg in South Africa and Krakow Business School in Poland.Findings/implications: From the t-tests statistically significant differences between the two groups were found on 10 of the newly defined scales. Except on one scale, the South African students scored higher than the Polish students.Originality/value of research: This is the first study comparing differences between master’s business management students from two culturally diverse countries, South Africa and Poland, in terms of entrepreneurial intent and its antecedents.Conclusion: Possible reasons for the differences were offered as gleaned from other research, but further research is required to identify the determining factors for the differences.

    Nations in the 21st century face a complex mix of environmental and social challenges, as highlighted by the on-going Sustainable Development Goals process. The "planetary boundaries" concept [Rockström J, et al. (2009) Nature 461(7263):472-475], and its extension through the addition of social well-being indicators to create a framework for "safe and just" inclusive sustainable development [Raworth K (2012) Nature Climate Change 2(4):225-226], have received considerable attention in science and policy circles. As the chief aim of this framework is to influence public policy, and this happens largely at the national level, we assess whether it can be used at the national scale, using South Africa as a test case. We developed a decision-based methodology for downscaling the framework and created a national "barometer" for South Africa, combining 20 indicators and boundaries for environmental stress and social deprivation. We find that it is possible to maintain the original design and concept of the framework while making it meaningful in the national context, raising new questions and identifying priority areas for action. Our results show that South Africa has exceeded its environmental boundaries for biodiversity loss, marine harvesting, freshwater use, and climate change, and social deprivation is most severe in the areas of safety, income, and employment. Trends since 1994 show improvement in nearly all social indicators, but progression toward or over boundaries for most environmental indicators. The barometer shows that achieving inclusive sustainable development in South Africa requires national and global action on multiple fronts, and careful consideration of the interplay between different environmental domains and development strategies.

    Fictional narratives have rarely been used in medical anthropological research. This article illustrates the value of such narratives by examining how young people in southeastern Nigeria navigate the cultural resources available to them to make sense of HIV in their creative writing. Using thematic data analysis and narrative-based methodologies, it analyzes a sample (N = 120) from 1,849 narratives submitted by Nigerian youth to the 2005 Scenarios from Africa scriptwriting contest on the theme of HIV. The narratives are characterized by five salient themes: tragedy arising from the incompatibility of sex outside marriage and kinship obligations; female vulnerability and blame; peer pressure and moral ambivalence; conservative Christian sexual morality; and the social and family consequences of HIV. We consider the strengths and limitations of this narrative approach from a theoretical perspective and by juxtaposing our findings with those generated by Daniel Jordan Smith using standard ethnographic research methods with a similar Igbo youth population.

    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.

    Jairam R Lingappa

    Full Text Available BACKGROUND: Most HIV-1 transmission in Africa occurs among HIV-1-discordant couples (one partner HIV-1 infected and one uninfected who are unaware of their discordant HIV-1 serostatus. Given the high HIV-1 incidence among HIV-1 discordant couples and to assess efficacy of interventions for reducing HIV-1 transmission, HIV-1 discordant couples represent a critical target population for HIV-1 prevention interventions and prevention trials. Substantial regional differences exist in HIV-1 prevalence in Africa, but regional differences in HIV-1 discordance among African couples, has not previously been reported. METHODOLOGY/PRINCIPAL FINDINGS: The Partners in Prevention HSV-2/HIV-1 Transmission Trial ("Partners HSV-2 Study", the first large HIV-1 prevention trial in Africa involving HIV-1 discordant couples, completed enrollment in May 2007. Partners HSV-2 Study recruitment data from 12 sites from East and Southern Africa were used to assess HIV-1 discordance among couples accessing couples HIV-1 counseling and testing, and to correlate with enrollment of HIV-1 discordant couples. HIV-1 discordance at Partners HSV-2 Study sites ranged from 8-31% of couples tested from the community. Across all study sites and, among all couples with one HIV-1 infected partner, almost half (49% of couples were HIV-1 discordant. Site-specific monthly enrollment of HIV-1 discordant couples into the clinical trial was not directly associated with prevalence of HIV-1 discordance, but was modestly correlated with national HIV-1 counseling and testing rates and access to palliative care/basic health care (r = 0.74, p = 0.09. CONCLUSIONS/SIGNIFICANCE: HIV-1 discordant couples are a critical target for HIV-1 prevention in Africa. In addition to community prevalence of HIV-1 discordance, national infrastructure for HIV-1 testing and healthcare delivery and effective community outreach strategies impact recruitment of HIV-1 discordant couples into HIV-1 prevention trials.

    Mveyange, Anthony Francis

    Estimating regional income inequality in Africa has been challenging due to the lack of reliable and consistent sub-national income data. I employ night lights data to circumvent this limitation. I find significant and positive associations between regional inequality visible through night lights...... and income in Africa. Thus, in the absence of income data, we can construct regional inequality proxies using night lights data. Further investigation on the night lights-based regional inequality trends reveals two main findings: first, increasing regional inequality trends between 1992 and 2003; and second......, declining regional inequality trends between 2004 and 2012....

    Using the GeoSentinel database, an analysis of ill patients returning from throughout sub-Saharan Africa over a 13-year period was performed. Systemic febrile illness, dermatologic, and acute diarrheal illness were the most common syndromic groupings, whereas spotted fever group rickettsiosis was the most common individual diagnosis for travelers to South Africa. In contrast to the rest of sub-Saharan Africa, only six cases of malaria were documented in South Africa travelers. Vaccine-preventable diseases, typhoid, hepatitis A, and potential rabies exposures were uncommon in South Africa travelers. Pre-travel advice for the travelers to the 2010 World Cup should be individualized according to these findings.

    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

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

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

    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

    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.

  20. Voluntary medical male circumcision: a qualitative study exploring the challenges of costing demand creation in eastern and southern Africa.

    Directory of Open Access Journals (Sweden)

    Jane T Bertrand

    Full Text Available BACKGROUND: This paper proposes an approach to estimating the costs of demand creation for voluntary medical male circumcision (VMMC scale-up in 13 countries of eastern and southern Africa. It addresses two key questions: (1 what are the elements of a standardized package for demand creation? And (2 what challenges exist and must be taken into account in estimating the costs of demand creation? METHODS AND FINDINGS: We conducted a key informant study on VMMC demand creation using purposive sampling to recruit seven people who provide technical assistance to government programs and manage budgets for VMMC demand creation. Key informants provided their views on the important elements of VMMC demand creation and the most effective funding allocations across different types of communication approaches (e.g., mass media, small media, outreach/mobilization. The key finding was the wide range of views, suggesting that a standard package of core demand creation elements would not be universally applicable. This underscored the importance of tailoring demand creation strategies and estimates to specific country contexts before estimating costs. The key informant interviews, supplemented by the researchers' field experience, identified these issues to be addressed in future costing exercises: variations in the cost of VMMC demand creation activities by country and program, decisions about the quality and comprehensiveness of programming, and lack of data on critical elements needed to "trigger the decision" among eligible men. CONCLUSIONS: Based on this study's findings, we propose a seven-step methodological approach to estimate the cost of VMMC scale-up in a priority country, based on our key assumptions. However, further work is needed to better understand core components of a demand creation package and how to cost them. Notwithstanding the methodological challenges, estimating the cost of demand creation remains an essential element in deriving

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.

    Journal article about Reliability Centered Maintenance (RCM) methodologies used by United Space Alliance, LLC (USA) in support of the Space Shuttle Program at Kennedy Space Center. The USA Reliability Centered Maintenance program differs from traditional RCM programs because various methodologies are utilized to take advantage of their respective strengths for each application. Based on operational experience, USA has customized the traditional RCM methodology into a streamlined lean logic path and has implemented the use of statistical tools to drive the process. USA RCM has integrated many of the L6S tools into both RCM methodologies. The tools utilized in the Measure, Analyze, and Improve phases of a Lean Six Sigma project lend themselves to application in the RCM process. All USA RCM methodologies meet the requirements defined in SAE JA 1011, Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes. The proposed article explores these methodologies.

    I work in the socio-political and economic space in dealing with BRICS and other frontier and emerging markets' engagement in Africa.My focus is on large commercial and industrial.deals,especially high-level dialogue,as well as small-and-medium trading initiatives … in all,capturing the opportunity and growth story that is Africa today.I find I have to constantly defend the fundamentals that underpin the Chinese deals,their trade and political interactions.Yet as I am by no means an apologist,I do however want to briefly untangle just a modicum of the blatantly false and baseless arguments against the Chinese in Africa.This debate would require a book in itself,and there is no better one than the acclaimed Professor Brautigam's The Dragon's Gift in which expertly and stoically debunks the many myths so liberally and limply salted with hot-blooded ire by the masses against the emerging giant.

    There is a need to improve the rational use of antibiotics across continents including Africa. This has resulted in initiatives in Botswana including treatment guidelines and the instigation of Antibiotic Stewardship Programs (ASPs). The next steps involve a greater understanding of current antibiotic utilization and resistance patterns (AMR). This resulted in a 2-day meeting involving key stakeholders principally from Botswana to discuss key issues including AMR rates as well as ASPs in both the public and private sectors. Following this, the findings will be used to plan future studies across Africa including point prevalence studies. The findings will be presented in July 2016 at the next Medicines Utilization Research in Africa meeting will ideally serve as a basis for planning future pertinent interventional studies to enhance the rational use of antibiotics in Botswana and wider.

    Searching for life in astromaterials to be delivered from the future missions to extraterrestrial bodies is undoubtedly related to studies of the properties and signatures of living microbial cells and microfossils on Earth. As model terrestrial analogs of Martian polar subsurface layers are often regarded the Antarctic glacier and Earth permafrost habitats where alive microbial cells preserved viability for millennia years due to entering the anabiotic state. For the future findings of viable microorganisms in samples from extraterrestrial objects, it is important to use a combined methodology that includes classical microbiological methods, plating onto nutrient media, direct epifluorescence and electron microscopy examinations, detection of the elemental composition of cells, radiolabeling techniques, PCR and FISH methods. Of great importance is to ensure authenticity of microorganisms (if any in studied samples) and to standardize the protocols used to minimize a risk of external contamination. Although the convincing evidence of extraterrestrial microbial life will may come from the discovery of living cells in astromaterials, biomorphs and microfossils must also be regarded as a target in search of life evidence bearing in mind a scenario that alive microorganisms had not be preserved and underwent mineralization. Under the laboratory conditions, processes that accompanied fossilization of cyanobacteria were reconstructed, and artificially produced cyanobacterial stromatolites resembles by their morphological properties those found in natural Earth habitats. Regarding the vital importance of distinguishing between biogenic and abiogenic signatures and between living and fossil microorganisms in analyzed samples, it is worthwhile to use some previously developed approaches based on electron microscopy examinations and analysis of elemental composition of biomorphs in situ and comparison with the analogous data obtained for laboratory microbial cultures and

    2017-02-01

    This paper examines regional and global co-movement of Africa's stock markets using the three-dimensional continuous Morlet wavelet transform methodology. The analyses which are done in segments investigate co-movements with global markets; bilateral exchange rates expressed in US dollars and euro; and four regional markets in Africa. First, we find evidence of stronger co-movements broadly narrowed to short-run fluctuations. The co-movements are time-varying and commonly non-homogeneous - with phase difference arrow vectors implying lead-lag relationships. The presence of lead-lag effects and stronger co-movements at short-run fluctuations may induce arbitrage and diversification opportunities to both local and international investors with long-term investment horizons. The findings also reveal that some African equity markets are, to a degree, segmented from volatilities of the dollar and euro exchange rates. Thus, inferring that, ceteris paribus, international investors may diversify their portfolio investments across those markets without worrying about the effects of currency price volatility.

    Functional verification is an art as much as a science. It requires not only creativity and cunning, but also a clear methodology to approach the problem. The Open Verification Methodology (OVM) is a leading-edge methodology for verifying designs at multiple levels of abstraction. It brings together ideas from electrical, systems, and software engineering to provide a complete methodology for verifying large scale System-on-Chip (SoC) designs. OVM defines an approach for developing testbench architectures so they are modular, configurable, and reusable. This book is designed to help both novic

  8. The geographical distribution and burden of trachoma in Africa.

    Full Text Available There remains a lack of epidemiological data on the geographical distribution of trachoma to support global mapping and scale up of interventions for the elimination of trachoma. The Global Atlas of Trachoma (GAT was launched in 2011 to address these needs and provide standardised, updated and accessible maps. This paper uses data included in the GAT to describe the geographical distribution and burden of trachoma in Africa.Data assembly used structured searches of published and unpublished literature to identify cross-sectional epidemiological data on the burden of trachoma since 1980. Survey data were abstracted into a standardised database and mapped using geographical information systems (GIS software. The characteristics of all surveys were summarized by country according to data source, time period, and survey methodology. Estimates of the current population at risk were calculated for each country and stratified by endemicity class.At the time of writing, 1342 records are included in the database representing surveys conducted between 1985 and 2012. These data were provided by direct contact with national control programmes and academic researchers (67%, peer-reviewed publications (17% and unpublished reports or theses (16%. Prevalence data on active trachoma are available in 29 of the 33 countries in Africa classified as endemic for trachoma, and 1095 (20.6% districts have representative data collected through population-based prevalence surveys. The highest prevalence of active trachoma and trichiasis remains in the Sahel area of West Africa and Savannah areas of East and Central Africa and an estimated 129.4 million people live in areas of Africa confirmed to be trachoma endemic.The Global Atlas of Trachoma provides the most contemporary and comprehensive summary of the burden of trachoma within Africa. The GAT highlights where future mapping is required and provides an important planning tool for scale-up and surveillance of trachoma

    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.

    Full Text Available INTRODUCTION: To effectively address HIV/AIDS in Africa, evidence on preventing new infections and providing effective treatment is needed. Ideally, decisions on which interventions are effective should be based on evidence from randomized controlled trials (RCTs. Our previous research described African RCTs of HIV/AIDS reported between 1987 and 2003. This study updates that analysis with RCTs published between 2004 and 2008. OBJECTIVES: To describe RCTs of HIV/AIDS conducted in Africa and reported between 2004 and 2008. METHODS: We searched the Cochrane HIV/AIDS Specialized Register in September 2009. Two researchers independently evaluated studies for inclusion and extracted data using standardized forms. Details included location of trials, interventions, methodological quality, location of principal investigators and funders. RESULTS: Our search identified 834 RCTs, with 68 conducted in Africa. Forty-three assessed prevention-interventions and 25 treatment-interventions. Fifteen of the 43 prevention RCTs focused on preventing mother-to-child HIV transmission. Thirteen of the 25 treatment trials focused on opportunistic infections. Trials were conducted in 16 countries with most in South Africa (20, Zambia (12 and Zimbabwe (9. The median sample size was 628 (range 33-9645. Methods used for the generation of the allocation sequence and allocation concealment were adequate in 38 and 32 trials, respectively, and 58 reports included a CONSORT recommended flow diagram. Twenty-nine principal investigators resided in the United States of America (USA and 18 were from African countries. Trials were co-funded by different agencies with most of the funding obtained from USA governmental and non-governmental agencies. Nineteen pharmaceutical companies provided partial funding to 15 RCTs and African agencies co-funded 17 RCTs. Ethical approval was reported in 65 trials and informed consent in 61 trials. CONCLUSION: Prevention trials dominate the trial

  18. Massive Open Online Courses for Africa by Africa

    Directory of Open Access Journals (Sweden)

    Benedict Oyo

    2014-12-01

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

    2009-10-01

    A systematic review of the published literature on bacterial resistance in Central Africa between 1955 and 2008 was performed. Eighty-three publications from seven countries were retrieved, the majority presenting data on enteric and other gram-negative pathogens. Despite methodological limitations in many studies, alarming resistance rates are noted in nearly all pathogens. Of special concern are multidrug resistance in Shigella and Salmonella spp. and the emergence of meticillin-resistant Staphylococcus aureus, high-level penicillin-resistant Streptococcus pneumoniae and extended-spectrum beta-lactamases among gram-negative pathogens. These findings make clear that the Central African region shares the worldwide trend of increasing antimicrobial resistance and is in urgent need of sound surveillance based on competent and affordable microbiology to provide clear data on antimicrobial resistance. These data could enable redaction of local treatment guidelines and fuel national and regional policies to contain antimicrobial resistance.

    We present here the methodology and the results of 5-member ensemble simulation of the climate of Africa for the period 1950-2100 using climate modelling system PRECIS over the CORDEX Africa domain. The boundary conditions for the regional model simulations were selected from a 17-member perturbed physics ensemble based on the HadCM3 global climate model (Murphy et al. 2007) following the methodology described in McSweeney et al 2012. Such an approach was selected in order to provide a good representation of the overall ensemble spread over a number of sub regions while at the same time avoiding members which have demonstrate particularly unrealistic characteristics in their baseline climate. In the simulations a special attention was given to the representation of some inland water bodies, such as lake Victoria, whose impact on the regional climate was believed to be significant thus allowing for the representation of some regional processes (e.g. land-lake breezes) that were not represented in the global models. In particular the SSTs of the lakes were corrected to better represent the local climatological values. The results suggest that RCM simulations improve the fit to observations of precipitation and temperature in most of the African sub-regions (e.g. North Africa, West Sahel). Also, the range of RCM projections is often different to those from the GCMs in these regions. We discuss the reasons for and links between these results and their implications for use in informing adaptation policy at regional level.

  8. An analysis of audit committee effectiveness at the largest listed companies in South Africa from a CFO and audit committee perspective

    Ben Marx

    2009-12-01

    Full Text Available Purpose: The purpose of the study is to investigate and analyse the effective functioning of audit committees at the largest listed companies in South Africa.Problem investigated: The modern audit committee is often seen as the panacea of the corporate world and as such is looked upon to cure all the financial reporting and control-related problems of entities. Audit committees are, however, not always as effective as they are held to be, as is evidenced by the many well-known corporate scandals and business failures that occurred where audit committees existed and fraudulent financial reporting, audit failures, internal control breakdowns and other irregularities prevailed. The modern audit committee will be of value only if it is properly constituted, is functioning effectively and if its role is clearly understood by all the parties concerned. The research problem investigated stems precisely from this issue, and the paper therefore aims to analyse the effective functioning of the audit committees at the largest listed companies in South Africa. Methodology: The study empirically tested the audit committee practices at the largest listed companies in South Africa. This was done through questionnaires addressed to the CFOs and audit committee chairs. Findings: The study found that audit committees at the largest listed companies in South Africa are well established, properly constituted, have the authority and resources to effectively discharge their responsibilities and consist of members who act independently and who have the right mix of appropriate experience, financial literacy and financial expertise amongst their members. The audit committee's role was found to be generally well understood and supported by the board and the Chief Financial Officers. It was further found that the audit committees are effective in discharging their oversight responsibilities on the board's behalf, with the only real exception being their effectiveness

  14. Measuring tangibility and assurance as determinants of service quality for public health care in South Africa

    Directory of Open Access Journals (Sweden)

    J. De Jager

    2007-12-01

    Full Text Available Purpose: The purpose of this research is to measure service quality offered to patients treated in a government controlled hospital in South Africa. Desig/Methodology/Approach: A service satisfaction survey was conducted amongst patients treated at a provincial hospital in Gauteng. The attitudes of the patients were tested regarding pre-identified service quality aspects related to health care. Tangibility and assurance categories are analysed for the purposes of this paper. A total of 583 in- and out-patients were selected at random and were personally interviewed. A five point Likert type scale was used to measure their expectations and perceived performance. Findings: These indicated patient dissatisfaction with both service quality dimensions measured, although significant differences exist between in- and out-patients. Personal safety and cleanliness of facilities were regarded as the most important variables in the assurance and tangibility dimensions. The level of satisfaction was the highest for clear information signage and communication at an understandable level in the tangibility-and assurance categories, respectively. Implications: This paper presents a comprehensive framework for prioritising important issues by provincial hospital management policy makers to satisfy patients' expectations and, because they have more authority over expenditure, the findings are important in the interest of supplying acceptable health care. Originality/Value: This study challenges existing work on health care services. Its significance lies in investigating the diversified health care needs and wants of various cultural groups in South Africa, because it focuses on service quality as experienced by in- and out-patients. It offers a new framework from an original South African perspective, focusing on differences and similarities between in- and outpatients of a Gauteng public hospital.

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.

  20. 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.

    We show that Atkinson's (Reports, 15 April 2011, p. 346) intriguing proposal--that global linguistic diversity supports a single language origin in Africa--is an artifact of using suboptimal data, biased methodology, and unjustified assumptions. We criticize his approach using more suitable data, and we additionally provide new results suggesting a more complex scenario for the emergence of global linguistic diversity.

    ABSTRACT Design Methodology shall be seen as our understanding of how to design; it is an early (emerging late 60ies) and original articulation of teachable and learnable methodics. The insight is based upon two sources: the nature of the designed artefacts and the nature of human designing. Today...... Design Methodology is part of our practice and our knowledge about designing, and it has been strongly supported by the establishing and work of a design research community. The aim of this article is to broaden the reader¿s view of designing and Design Methodology. This is done by sketching...... the development of Design Methodology through time and sketching some important approaches and methods. The development is mainly forced by changing industrial condition, by the growth of IT support for designing, but also by the growth of insight into designing created by design researchers....

  11. Livestock First Reached Southern Africa in Two Separate Events.

    Directory of Open Access Journals (Sweden)

    Karim Sadr

    Full Text Available After several decades of research on the subject, we now know when the first livestock reached southern Africa but the question of how they got there remains a contentious topic. Debate centres on whether they were brought with a large migration of Khoe-speakers who originated from East Africa; or whether the livestock were traded down-the-line among hunter-gatherer communities; or indeed whether there was a long history of diverse small scale population movements in this part of the world, one or more of which 'infiltrated' livestock into southern Africa. A new analysis of the distribution of stone toolkits from a sizeable sample of sub-equatorial African Later Stone Age sites, coupled with existing knowledge of the distribution of the earliest livestock remains and ceramics vessels, has allowed us to isolate two separate infiltration events that brought the first livestock into southern Africa just over 2000 years ago; one infiltration was along the Atlantic seaboard and another entered the middle reaches of the Limpopo River Basin. These findings agree well with the latest results of genetic research which together indicate that multiple, small-scale infiltrations probably were responsible for bringing the first livestock into southern Africa.

    2011-01-01

    This paper investigates economic, political, and institutional constraints to fiscal policy implementation in sub-saharan Africa. We find that planned fiscal adjustments or expansions are less likely to be implemented the larger they are, the more inaccurate the growth forecasts they are based on, the more fragile the regulatory system in the country, and the weaker the institutions framing the design, approval, and execution of the budget. The findings support ongoing efforts in the region t...

  13. 10-daily soil erosion modelling over sub-Saharan Africa.

    Science.gov (United States)

    Symeonakis, Elias; Drake, Nick

    2010-02-01

    Soil erosion is considered to be one of the greatest environmental problems of sub-Saharan Africa. This paper investigates the advantages and disadvantages of modelling soil erosion at the continental scale and suggests an operational methodology for mapping and quantifying 10-daily water runoff and soil erosion over this scale using remote sensing data in a geographical information system framework. An attempt is made to compare the estimates of this study with general data on the severity of soil erosion over Africa and with measured rates of soil loss at different locations over the continent. The results show that the measured and estimated rates of erosion are in some areas very similar and in general within the same order of magnitude. The importance and the potential of using the soil erosion estimates with simple models and easily accessible free data for various continental-scale environmental applications are also demonstrated.

  14. Cardiomegaly in tropical Africa.

    Science.gov (United States)

    Tomaszewski, Ryszard

    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.

    2010-01-01

    The first African School of Physics draws to a close tomorrow, and I’m proud that CERN has been a part of it. 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 ...

    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...

    Hai-Tao Tsao

    2015-08-01

    Full Text Available The purpose of this paper is to discuss the consequences of China’s outward direct investments in Africa in terms of enterprises with different ownership types. First, this paper contributes to the examination of a large number of Chinese enterprises’ investment projects in Africa. Second, in addition to the investment activities of central state-owned enterprises, investment activities initiated by local state-owned enterprises and private enterprises are also addressed in this paper. Third, this paper demonstrates the diversity ofChinese investment in Africa through the discussion of a large number of cases. We find that the motives of central state-owned enterprises comply with government policies. However, most private enterprises and non-central state-owned enterprises invest in Africa for profit considerations. This paper concludes that China’s investments in Africa are diverse and complex and cannot be explained using a single model of the extant theories.

  19. What Have We Learned From the Typhoid Fever Surveillance in Africa Program?

    Science.gov (United States)

    Baker, Stephen; Hombach, Joachim; Marks, Florian

    2016-03-15

    The Typhoid Fever Surveillance in Africa Program (TSAP) was established in 2009 to fill the data void concerning invasive Salmonella disease in sub-Saharan Africa, and to specifically estimate the burden of bloodstream infections caused by the key pathogen, Salmonella enterica serovar Typhi. TSAP has achieved this ambitious target, finding high incidences of typhoid fever in both rural and urban populations in several countries in sub-Saharan Africa. The results of TSAP will undoubtedly dictate the direction of future typhoid fever research in Africa, and at last provides a key piece of the disease burden jigsaw puzzle. With the dawn of new Vi conjugate vaccines against Salmonella Typhi, the next priority for the typhoid community must be providing the required data on these vaccines so they can be licensed and provided to those in high-risk groups and locations across sub-Saharan Africa.

  20. Barriers to the Implementation of the Health and Rehabilitation Articles of the United Nations Convention on the Rights of Persons with Disabilities in South Africa

    Science.gov (United States)

    Hussey, Meghan; MacLachlan, Malcolm; Mji, Gubela

    2017-01-01

    Background: The United Nations (UN) Convention on the Rights of Persons with Disabilities (CRPD) is a milestone in the recognition of the human rights of persons with disabilities, including the right to health and rehabilitation. South Africa has signed and ratified the CRPD but still has a long way to go in reforming policies and systems in order to be in compliance with the convention. This paper seeks to fill a gap in the literature by exploring what the barriers to the implementation of the health and rehabilitation articles of the CRPD are, as identified by representatives of the disability community. Methods: This investigation used a qualitative, exploratory methodology. 10 semi-structured interviews of a purposive sample of representatives of disabled persons organizations (DPOs), non-governmental organizations (NGOs), and service providers in South Africa were conducted. Participants were drawn from urban, peri-urban, and rural settings in order to reflect diverse perspectives within South Africa. Data was analysed using a multi-stage coding process to establish the main categories and relationships between them. Results: Six main categories of barriers to the implementation of the health and rehabilitation articles of the CRPD were identified. Attitude barriers including stigma and negative assumptions about persons with disabilities were seen as an underlying cause and influence on all of the other categories; which included political, financial, health systems, physical, and communication barriers. Conclusion: The findings of this study have important implications for strategies and actions to implement the CRPD. Given the centrality of attitudinal barriers, greater sensitization around the area of disability is needed. Furthermore, disability should be better integrated and mainstreamed into more general initiatives to develop the health system and improve the lives of persons living in poverty in South Africa.

    This document describes the contents of a digital database containing maximum potential aboveground biomass, land use, and estimated biomass and carbon data for 1980 and describes a methodology that may be used to extend this data set to 1990 and beyond based on population and land cover data. The biomass data and carbon estimates are for woody vegetation in Tropical Africa. These data were collected to reduce the uncertainty associated with the possible magnitude of historical releases of carbon from land use change. Tropical Africa is defined here as encompassing 22.7 x 10{sup 6} km{sup 2} of the earth`s land surface and includes those countries that for the most part are located in Tropical Africa. Countries bordering the Mediterranean Sea and in southern Africa (i.e., Egypt, Libya, Tunisia, Algeria, Morocco, South Africa, Lesotho, Swaziland, and Western Sahara) have maximum potential biomass and land cover information but do not have biomass or carbon estimate. The database was developed using the GRID module in the ARC/INFO{sup TM} geographic information system. Source data were obtained from the Food and Agriculture Organization (FAO), the U.S. National Geophysical Data Center, and a limited number of biomass-carbon density case studies. These data were used to derive the maximum potential and actual (ca. 1980) aboveground biomass-carbon values at regional and country levels. The land-use data provided were derived from a vegetation map originally produced for the FAO by the International Institute of Vegetation Mapping, Toulouse, France.

  2. Protocol for a scoping review of existing policies on the prevention and control of obesity across countries in Africa

    2017-01-01

    Introduction The obesity epidemic is a public health challenge for all, including low-income countries. The behavioural patterns known to contribute to the rise in obesity prevalence occur in an environmental context which is not conducive for healthy choices. A policy approach to obesity prevention constitutes a form of public intervention in that it extends beyond individuals to influence entire populations and is a mechanism for creating healthier environments. Little is known about obesity prevention policies in Africa. This scoping review seeks to examine the nature, extent and range of policies covering obesity prevention in Africa in order to assess how they align with international efforts in creating less obesogenic environments. This will help identify gaps in the approaches that are adopted in Africa. Methods and analysis Using the Arksey and O'Malley's scoping methodological framework as a guide, a comprehensive search of MEDLINE (PubMed), MEDLINE (EbscoHost) CINAHL (EbscoHost), Academic Search Complete (EbscoHost) and ISI Web of Science (Science Citation Index) databases will be carried out for peer reviewed journal articles related to obesity prevention policies using the African search filter. A grey literature search for policy documents and reports will also be conducted. There will be no language and date restrictions. Eligible policy documents and reports will be obtained and screened using the inclusion criteria. Data will be extracted and results analysed using descriptive numerical summary analysis and qualitative thematic analysis. Ethics and dissemination No primary data will be collected since all data that will be presented in this review are based on published articles and publicly available documents, and therefore ethics committee approval is not a requirement. The findings of this systematic review will be presented at workshops and conferences; and will be submitted for publication in peer-reviewed journal. This will also form a

  3. Adolescence as risk factor for adverse pregnancy outcome in Central Africa--a cross-sectional study.

    Directory of Open Access Journals (Sweden)

    Florian Kurth

    Full Text Available BACKGROUND: Sub-Saharan Africa has the highest rates of maternal and neonatal mortality worldwide. Young maternal age at delivery has been proposed as risk factor for adverse pregnancy outcome, yet there is insufficient data from Sub-Saharan Africa. The present study aimed to investigate the influence of maternal adolescence on pregnancy outcomes in the Central African country Gabon. METHODOLOGY AND PRINCIPAL FINDINGS: Data on maternal age, parity, birth weight, gestational age, maternal Plasmodium falciparum infection, use of bednets, and intake of intermittent preventive treatment of malaria in pregnancy were collected in a cross-sectional survey in 775 women giving birth in three mother-child health centers in Gabon. Adolescent women (≤16 years of age had a significantly increased risk to deliver a baby with low birth weight in univariable analysis (22.8%, 13/57, vs. 9.3%, 67/718, OR: 2.9, 95% CI: 1.5-5.6 and young maternal age showed a statistically significant association with the risk for low birth weight in multivariable regression analysis after correction for established risk factors (OR: 2.7; 95% CI: 1.1-6.5. In further analysis adolescent women were shown to attend significantly less antenatal care visits than adult mothers (3.3±1.9 versus 4.4±1.9 mean visits, p<0.01, n = 356 and this difference accounted at least for part of the excess risk for low birth weight in adolescents. CONCLUSION: Our data demonstrate the importance of adolescent age as risk factor for adverse pregnancy outcome. Antenatal care programs specifically tailored for the needs of adolescents may be necessary to improve the frequency of antenatal care visits and pregnancy outcomes in this risk group in Central Africa.

    The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

  5. Cooperation: New Players in Africa

    Directory of Open Access Journals (Sweden)

    Philippe Hugon

    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.

    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.

  7. Race, populations, and genomics: Africa as laboratory.

    Braun, Lundy; Hammonds, Evelynn

    2008-11-01

    Much of the recent debate over race, genetics, and health has focused on the extent to which typological notions of race have biological meaning. Less attention, however, has been paid to the assumptions about the nature of "populations" that both inform contemporary biological and medical research and that underlie the concept of race. Focusing specifically on Africa in the 1930s and 1940s, this paper explores the history of how fluid societies were transformed into bounded units amenable to scientific analysis. In the so-called "Golden Age of Ethnography," university-trained social anthropologists, primarily from Britain and South Africa, took to the field to systematically study, organize, and order the world's diverse peoples. Intent on creating a scientific methodology of neutral observation, they replaced amateur travelers, traders, colonial administrators, and missionaries as authoritative knowledge producers about the customs, beliefs, and languages of indigenous peoples. At the same time, linguists were engaged in unifying African languages and mapping language onto primordial "tribal" territories. We argue that the notion of populations or "tribes" as discrete units suitable for scientific sampling and classification emerged in the 1930s and 1940s with the ethnographic turn in social anthropology and the professionalization and institutionalization of linguistics in Western and South African universities. Once named and entered into international atlases and databases by anthropologists in the U.S., the existence of populations as bounded entities became self-evident, thus setting the stage for their use in large-scale population genetic studies and the contemporary reinvigoration of broad claims of difference based on population identification.

    2016-03-01

    Full Text Available The mining sector is a significant contributor to the gross domestic product of many global economies. Given the increasing trends in climate-induced disasters and the growing desire to find lasting solutions, information and communication technology (ICT has been introduced into the climate change adaptation mix. Climate change-induced extreme weather events such as flooding, drought, excessive fog, and cyclones have compounded the environmental challenges faced by the mining sector. This article presents the adoption of ICT innovation as part of the adaptation strategies towards reducing the mining sector’s vulnerability and exposure to climate change disaster risks. Document analysis and systematic literature review were adopted as the methodology. Findings from the study reflect how ICT intervention orchestrated changes in communication patterns which are tailored towards the reduction in climate change vulnerability and exposure. The research concludes with a proposition that ICT intervention must be part of the bigger and ongoing climate change adaptation agenda in the mining sector.Keywords: ICT; climate change; disaster risk reduction; mining; adaptation; South Africa

    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.

  13. The Exceptional State in Africa

    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)

    The South African Government has objective to provide universal access of electricity for its citizens and its electrification programme has been successful but focus has moved from numbers of connections to one of achieving sustainable socio-economic benefits. First-hand understanding was obtained of the complexity of socio-economic development where CSIR undertook a project in the rural areas of South Africa to identify electrification opportunities using renewable energy linked to economic activities. Lessons formed basis of a government funding implementation of pilot hybrid mini-grids to inform a future rollout. Results informed the development of distributed generation concepts and an integrated methodology.

  17. Poverty and blindness in Africa.

    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

    Event Tree(ET)/Fault Tree(FT) are significant methodology in Probabilistic Safety Assessment(PSA) for Nuclear Power Plants(NPPs). ET/FT methodology has the advantage for users to be able to easily learn and model. It enables better communication between engineers engaged in the same field. However, conventional methodologies are difficult to cope with the dynamic behavior (e.g. operation mode changes or sequence-dependent failure) and integrated situation of mechanical failure and human errors. Meanwhile, new possibilities are coming for the improved PSA by virtue of the dramatic development on digital hardware, software, information technology, and data analysis.. More specifically, the computing environment has been greatly improved with being compared to the past, so we are able to conduct risk analysis with the large amount of data actually available. One method which can take the technological advantages aforementioned should be the dynamic PSA such that conventional ET/FT can have time- and condition-dependent behaviors in accident scenarios. In this paper, we investigated the various enabling techniques for the dynamic PSA. Even though its history and academic achievement was great, it seems less interesting from industrial and regulatory viewpoint. Authors expect this can contribute to better understanding of dynamic PSA in terms of algorithm, practice, and applicability. In paper, the overview for the dynamic PSA was conducted. Most of methodologies share similar concepts. Among them, DDET seems a backbone for most of methodologies since it can be applied to large problems. The common characteristics sharing the concept of DDET are as follows: • Both deterministic and stochastic approaches • Improves the identification of PSA success criteria • Helps to limit detrimental effects of sequence binning (normally adopted in PSA) • Helps to avoid defining non-optimal success criteria that may distort the risk • Framework for comprehensively considering

  3. 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.

  6. Atlantic and indian oceans pollution in africa

    Science.gov (United States)

    Abubakar, Babagana

    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 incessant degreasing of the Sea Ports "Quay Aprons" along the Coastal cities of Lagos, Luanda, Cape Town etc are continuously polluting the Atlantic Ocean with chemicals. iii. Local wastes generated from the houses located in the coastal cities are always finding their ways into the Atlantic Ocean. NATURE OF POLLUTION OF THE INDIAN OCEAN i. Unlike the Atlantic ocean where petroleum is the major pollutant, the Indian Ocean is polluted by Toxic / Radioactive waste suspected to have been coming from the developed nations as reported by the United Nations Environmental Programme after the Tsunami disaster in December 2004 especially along the coast of Somalia. ii. The degreasing of the Quay Aprons at Port Elizabeth, Maputo, Dar-es-Salaam and Mongolism Sea Ports are also another major source polluting the Indian Ocean.

    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.

    During the 1950s to the end of the 1970s the United States Army developed the basic methodology to produce shelf-stable irradiated meat, seafood and poultry products. These products are normally packed without gravy, sauce or brine, as liquid is not required to sterilize the product as in the canning process. This leads to the distinctive "dried cooked" taste normally associated with roasts opposed to the casserole taste usually associated with tinned meats. The Biogam group at the Atomic Energy Corporation of South Africa is currently producing shelf-stable irradiated meats on a commercial basis. The meats are cooked, chilled, portioned, vacuum packed and irradiated to the required minimum dose of 45 kGy at a temperature of between -20 and -40°C to ensure absolute sterility even under tropical conditions. The product is packaged in a high quality four layer laminate pouch and will therefore not rust or burst even under adverse weather conditions and can be guaranteed for more than two years as long as the integrity of the packaging is maintained. Safari operators in remote parts of Africa, mountaineers, yachtsmen, canoeists and geological survey teams currently use shelf-stable irradiated meat products produced in South Africa.

  14. Plasmodium vivax Transmission in Africa.

    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

    Full Text Available Purpose: The purpose of the paper is to determine the levels of satisfaction in respect of pre identified internal marketing-related variables in a large provincial hospital in South Africa. Problem investigated: Low job satisfaction is often cited as a major cause of high turnover among health care providers worldwide. Likewise the Public Health Care Industry in South Africa is facing complex employee retention issues. In determining the reasons for high turnover an interest in evaluating employee satisfaction among health care providers has increased. Measuring components of job satisfaction will assist not only the health care organisations' management to understand hospital culture, but also to compile an effective internal marketing plan and strategy. Design/Methodology/Approach: A staff satisfaction survey was conducted amongst staff members at a provincial hospital in the Tshwane region, South Africa. Attitudes of staff on pre-identified staff satisfaction variables were assessed. These variables were employed to implement an internal marketing strategy. A list of variables was formulated after an extensive literature study had been conducted. A total of 416 staff members voluntarily completed a self-administered questionnaire. A five-point Likert type scale was used to measure the levels of satisfaction on staff-related issues, with a view to addressing issues in the internal marketing strategy. Findings : It was evident that the management principles currently employed by the management team were a cause for concern among staff members. Based on the analysis that identified the satisfaction variables best it was clear that management should take immediate steps to address the following issues : Clarification of hospital goals \\ objectives; Understanding the goals of the respective departments; The functioning of the Human resource department; Functioning of the overall hospital management; andImplications: This paper aims to present a

    Full Text Available Participatory research projects incorporating non-traditional, creative, and qualitative methodologies can produce results which are unexpected or divergent from original research proposals. These results are highly meaningful, yet challenging to express to an audience when the expectation is to write the findings in a linear and traditional format, such as in a graduate thesis. Within this article, we use an autoethnographic approach to describe our experiences with ethnodrama, from our perspectives as a graduate student and supervisor. We focus on a planned breast cancer ethnodrama pilot project, which developed into a healing yoga program instead. We question the traditional notion of successful research as being a linear, straightforward process. In doing so, we hope to create dialogue and support mentorship which acknowledges the "messiness" of research projects. We also assert that there is a need to embrace non-traditional methods for disseminating our "messy" research outcomes.

  6. Promoting renewable energy and energy efficiency in Africa: a framework to evaluate employment generation and cost effectiveness

    Science.gov (United States)

    Cantore, Nicola; Nussbaumer, Patrick; Wei, Max; Kammen, Daniel M.

    2017-03-01

    The ongoing debate over the cost-effectiveness of renewable energy (RE) and energy efficiency (EE) deployment often hinges on the current cost of incumbent fossil-fuel technologies versus the long-term benefit of clean energy alternatives. This debate is often focused on mature or ‘industrialized’ economies and externalities such as job creation. In many ways, however, the situation in developing economies is at least as or even more interesting due to the generally faster current rate of economic growth and of infrastructure deployment. On the one hand, RE and EE could help decarbonize economies in developing countries, but on the other hand, higher upfront costs of RE and EE could hamper short-term growth. The methodology developed in this paper confirms the existence of this trade-off for some scenarios, yet at the same time provides considerable evidence about the positive impact of EE and RE from a job creation and employment perspective. By extending and adopting a methodology for Africa designed to calculate employment from electricity generation in the U.S., this study finds that energy savings and the conversion of the electricity supply mix to renewable energy generates employment compared to a reference scenario. It also concludes that the costs per additional job created tend to decrease with increasing levels of both EE adoption and RE shares.

    Sub-Saharan Africa bears 69 % of the global burden of HIV, and strong evidence indicates an association between alcohol consumption, HIV risk behavior, and HIV incidence. However, characteristics of efficacious HIV-alcohol risk reduction interventions are not well known. The purpose of this systematic review is to summarize the characteristics and synthesize the findings of HIV-alcohol risk reduction interventions implemented in the region and reported in peer-reviewed journals. Of 644 citations screened, 19 met the inclusion criteria for this review. A discussion of methodological challenges, research gaps, and recommendations for future interventions is included. Relatively few interventions were found, and evidence is mixed about the efficacy of HIV-alcohol risk reduction interventions. There is a need to further integrate HIV-alcohol risk reduction components into HIV prevention programming and to document results from such integration. Additionally, research on larger scale, multi-level interventions is needed to identify effective HIV-alcohol risk reduction strategies.

  8. Geostatistical model-based estimates of Schistosomiasis prevalence among individuals aged ≤ 20 years in West Africa.

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available BACKGROUND: Schistosomiasis is a water-based disease that is believed to affect over 200 million people with an estimated 97% of the infections concentrated in Africa. However, these statistics are largely based on population re-adjusted data originally published by Utroska and colleagues more than 20 years ago. Hence, these estimates are outdated due to large-scale preventive chemotherapy programs, improved sanitation, water resources development and management, among other reasons. For planning, coordination, and evaluation of control activities, it is essential to possess reliable schistosomiasis prevalence maps. METHODOLOGY: We analyzed survey data compiled on a newly established open-access global neglected tropical diseases database (i to create smooth empirical prevalence maps for Schistosoma mansoni and S. haematobium for individuals aged ≤ 20 years in West Africa, including Cameroon, and (ii to derive country-specific prevalence estimates. We used Bayesian geostatistical models based on environmental predictors to take into account potential clustering due to common spatially structured exposures. Prediction at unobserved locations was facilitated by joint kriging. PRINCIPAL FINDINGS: Our models revealed that 50.8 million individuals aged ≤ 20 years in West Africa are infected with either S. mansoni, or S. haematobium, or both species concurrently. The country prevalence estimates ranged between 0.5% (The Gambia and 37.1% (Liberia for S. mansoni, and between 17.6% (The Gambia and 51.6% (Sierra Leone for S. haematobium. We observed that the combined prevalence for both schistosome species is two-fold lower in Gambia than previously reported, while we found an almost two-fold higher estimate for Liberia (58.3% than reported before (30.0%. Our predictions are likely to overestimate overall country prevalence, since modeling was based on children and adolescents up to the age of 20 years who are at highest risk of infection. CONCLUSION

  9. Declining incidence of malaria imported into the UK from West Africa

    2008-11-01

    Full Text Available Abstract Background Two thirds of all falciparum malaria cases reported in the United Kingdom (UK are acquired in West Africa (WA. To ensure recommendations and guidelines for malaria prophylaxis in travellers to West Africa correlate to the risk of infection, a study was undertaken to examine recent trends and predict future patterns of imported malaria acquired by UK residents visiting West Africa and West African visitors to the UK between 1993 and 2006. Methods and Results Using passenger numbers and malaria surveillance reports, the data revealed a 2.3-fold increase in travel to West Africa with a five-fold increase in travelers visiting friends and relatives (VFR. Malaria incidence fell through the study period, the greatest decline noted in VFR with a fall from 196 cases/1,000 person-years to 52 cases/1,000 person-years, 9.8% per year p Discussion The reduction in incidence among all three groups of travellers may be explained by several factors; changing chemoprophylaxis usage and/or increased travel in urban areas where malaria risk has declined over the past decade, or widespread reduction in malaria transmission in West Africa. Conclusion With the reduction in malaria incidence seen in both visitors to and from West Africa, the most rational explanation for these findings is a fall in malaria transmission in West Africa, which may require a change in chemoprophylaxis policy for UK travelers over the next 5–10 years.

  11. Burn care in South Africa: a micro cosmos of Africa.

    Science.gov (United States)

    2014-07-01

    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.

  15. Dynamic locomotor capabilities revealed by early dinosaur trackmakers from southern Africa.

    Directory of Open Access Journals (Sweden)

    Jeffrey A Wilson

    Full Text Available BACKGROUND: A new investigation of the sedimentology and ichnology of the Early Jurassic Moyeni tracksite in Lesotho, southern Africa has yielded new insights into the behavior and locomotor dynamics of early dinosaurs. METHODOLOGY/PRINCIPAL FINDINGS: The tracksite is an ancient point bar preserving a heterogeneous substrate of varied consistency and inclination that includes a ripple-marked riverbed, a bar slope, and a stable algal-matted bar top surface. Several basal ornithischian dinosaurs and a single theropod dinosaur crossed its surface within days or perhaps weeks of one another, but responded to substrate heterogeneity differently. Whereas the theropod trackmaker accommodated sloping and slippery surfaces by gripping the substrate with its pedal claws, the basal ornithischian trackmakers adjusted to the terrain by changing between quadrupedal and bipedal stance, wide and narrow gauge limb support (abduction range = 31 degrees , and plantigrade and digitigrade foot posture. CONCLUSIONS/SIGNIFICANCE: The locomotor adjustments coincide with changes in substrate consistency along the trackway and appear to reflect 'real time' responses to a complex terrain. It is proposed that these responses foreshadow important locomotor transformations characterizing the later evolution of the two main dinosaur lineages. Ornithischians, which shifted from bipedal to quadrupedal posture at least three times in their evolutionary history, are shown to have been capable of adopting both postures early in their evolutionary history. The substrate-gripping behavior demonstrated by the early theropod, in turn, is consistent with the hypothesized function of pedal claws in bird ancestors.

  16. High genetic differentiation between the M and S molecular forms of Anopheles gambiae in Africa.

    Caroline Esnault

    Full Text Available BACKGROUND: Anopheles gambiae, a major vector of malaria, is widely distributed throughout sub-Saharan Africa. In an attempt to eliminate infective mosquitoes, researchers are trying to develop transgenic strains that are refractory to the Plasmodium parasite. Before any release of transgenic mosquitoes can be envisaged, we need an accurate picture of the differentiation between the two molecular forms of An. gambiae, termed M and S, which are of uncertain taxonomic status. METHODOLOGY/PRINCIPAL FINDINGS: Insertion patterns of three transposable elements (TEs were determined in populations from Benin, Burkina Faso, Cameroon, Ghana, Ivory Coast, Madagascar, Mali, Mozambique, Niger, and Tanzania, using Transposon Display, a TE-anchored strategy based on Amplified Fragment Length Polymorphism. The results reveal a clear differentiation between the M and S forms, whatever their geographical origin, suggesting an incipient speciation process. CONCLUSIONS/SIGNIFICANCE: Any attempt to control the transmission of malaria by An. gambiae using either conventional or novel technologies must take the M/S genetic differentiation into account. In addition, we localized three TE insertion sites that were present either in every individual or at a high frequency in the M molecular form. These sites were found to be located outside the chromosomal regions that are suspected of involvement in the speciation event between the two forms. This suggests that these chromosomal regions are either larger than previously thought, or there are additional differentiated genomic regions interspersed with undifferentiated regions.

  18. Human rights and health: challenges for training nurses in South Africa.

    Science.gov (United States)

    London, L; Baldwin-Ragaven, L

    2008-03-01

    The need for health professionals to address their human rights obligations has emerged in the last decade both internationally as well as nationally following the findings of South Africa's Truth and Reconciliation Commission. Support for human rights norms has become a priority for institutions as well as practitioners within the health sector. Training plays a crucial role in shaping health professional practice. In addition to creating a clear understanding of the linkages between human rights and health, educators can role-model how health professionals should act to support human rights. This article explores human rights derived from the South African Constitution in relation to the obligation on health professionals to respect, protect, promote and fulfill human rights. The implications of this commitment to human rights training of nurses are discussed, drawing on the authors' nine years of experience in running courses for South African health professional educators. Themes include: developing core competencies for human rights in health professional curricula, identifying appropriate instructional methodologies and assessment tools suited to the content and context of human rights, and engaging the institutional environment for human rights teaching, at both the level of institutional culture and strategic implementation. At a time when there are increasing demands on the nursing profession to assume greater responsibility and develop versatility in its scope of practice, key challenges are posed for teaching and realising human rights.

    Full Text Available This paper scrutinizes the recent proposal made by Lassiter (2008 that the dichotomy between Chomskyan internalism and Dummett-type externalism is misguided and should be overcome by an approach that incorporates sociolinguistic concepts such as speakers’ dispositions to defer. We argue that Lassiter’s arguments are flawed and based on a serious misunder-standing of the internalist approach to the study of natural language, failing to appreciate its methodological nature and conclude that Lassiter’s socio-linguistic approach is just another instance of externalist attempts with little hope of scientific achievement.

  3. From Elections to Accountability in Africa?

    2014-07-01

    Full Text Available Competitive elections are becoming institutionalized in Africa. But elections have proven an uncertain mechanism for guaranteeing the accountability of political leaders. One reason is that political accountability has numerous attitudinal, behavioral and institutional requirements, of which popular participation in open elections is only one. Instead, we propose a framework of four elements that together comprise a holistic system of political accountability: (a demand for vertical accountability; (b supply of vertical accountability; (c demand for horizontal accountability; and (d supply of horizontal accountability.The article measures each of these elements using data from Afrobarometer Round 5 (2011–13. On one hand, we find that the weakest link in the chain of accountability remains the vertical one between largely passive electors and evasive legislative agents. On the other hand, we find that the African citizens surveyed think that elections strengthen the institutional autonomy of parliament, thus enabling a greater measure of horizontal accountability. But this pattern of accountability begs several lingering concerns. We wonder whether citizens have sufficient information to accurately monitor the relationship between president and parliament under a democratic constitution, and we find that the quality of elections, along with the partisan predispositions of electoral winners, condition the effect of elections on popular perceptions of accountability.

    2014-06-01

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

    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.

  8. Africa and Precambrian biological evolution

    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

    2006-08-01

    Full Text Available Abstract Background Oculocutaneous albinism (OCA is a genetically inherited autosomal recessive condition and OCA2, tyrosine-positive albinism, is the most prevalent type found throughout Africa. Due to the lack of melanin, people with albinism are more susceptible to the harmful effects of ultraviolet radiation exposure. This population must deal with issues such as photophobia, decreased visual acuity, extreme sun sensitivity and skin cancer. People with albinism also face social discrimination as a result of their difference in appearance. The World Health Organization is currently investigating the issues concerning this vulnerable population. Methods Systematic electronic search of articles in PubMed concerning albinism in Africa. Furthermore, a World Health Organization (WHO pilot survey of albinism was drafted in English, French and Portuguese, and distributed to African countries through WHO African Regional Offices (AFRO in an attempt to gather further information on albinism. Results Epidemiologic data on albinism, such as prevalence, were available for South Africa, Zimbabwe, Tanzania and Nigeria. Prevalences as high as 1 in 1,000 were reported for selected populations in Zimbabwe and other specific ethnic groups in Southern Africa. An overall estimate of albinism prevalences ranges from 1/5,000 – 1/15,000. In addition, both the literature review and the survey underscored the medical and social issues facing people with albinism. Conclusion The estimated prevalence of albinism suggests the existence of tens of thousands of people living with albinism in Africa. This finding reiterates the need for increased awareness of and public health interventions for albinism in order to better address the medical, psychological and social needs of this vulnerable population.

  1. 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.

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

  3. The Precambrian crustal structure of East Africa

    Tugume, Fred Alex

    In this thesis, the Precambrian crustal structure of East African is investigated along with the crustal structures of three Cenozoic rift basins located in the western branch of the East African Rift System (EARS). In the first part of the thesis, P-wave receiver functions are modeled using the H-k method to obtain new insights about the bulk composition and thickness of the crust for Precambrian terrains throughout East Africa. The average crustal thickness for all but one of the terrains is between 37 and 39 km. An exception is the Ubendian terrain, which has an average crustal thickness 42 km. In all terrains, the average Poisson's ratio is similar, ranging from 0.25 to 0.26, indicating a bulk crustal composition that is felsic to intermediate. The main finding of this study is that crustal structure is similar across all terrains, which span more than 4.0 Ga of earth history. There is no discernable difference in the crustal thicknesses and Poisson's ratios between the Archean and Proterozoic terrains, or between the Proterozoic terrains, unlike the variability in Precambrian crustal structure found in many other continents. In the second part of the thesis, a joint inversion of Rayleigh wave phase and group velocities and receiver functions was used to investigate the shear wave velocity structure of the crust and uppermost mantle beneath the Precambrian terrains of East Africa. In comparison with other areas of similar age in southern and western Africa where the same joint inversion method has been applied, I find that while there is little difference in the mean shear wave velocities for the entire crust across all of the Precambrian terrains, and also few differences in the thickness of the crust, there exists substantial variability in lower crustal structure. This variability is reflected primarily in the thickness of the lower crustal layers with shear wave velocities ≥ 4.0 km/s. This variability is found both within terrains of the same age (i

    Full Text Available In this article, the author challenges the popular public conception that Christianity in Africa is a latecomer introduced only with the advent of colonialism. 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.

  6. 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.

  8. Risk maps of Lassa fever in West Africa.

    Directory of Open Access Journals (Sweden)

    Elisabeth Fichet-Calvet

    Full Text Available BACKGROUND: Lassa fever is caused by a viral haemorrhagic arenavirus that affects two to three million people in West Africa, causing a mortality of between 5,000 and 10,000 each year. The natural reservoir of Lassa virus is the multi-mammate rat Mastomys natalensis, which lives in houses and surrounding fields. With the aim of gaining more information to control this disease, we here carry out a spatial analysis of Lassa fever data from human cases and infected rodent hosts covering the period 1965-2007. Information on contemporary environmental conditions (temperature, rainfall, vegetation was derived from NASA Terra MODIS satellite sensor data and other sources and for elevation from the GTOPO30 surface for the region from Senegal to the Congo. All multi-temporal data were analysed using temporal Fourier techniques to generate images of means, amplitudes and phases which were used as the predictor variables in the models. In addition, meteorological rainfall data collected between 1951 and 1989 were used to generate a synoptic rainfall surface for the same region. METHODOLOGY/PRINCIPAL FINDINGS: Three different analyses (models are presented, one superimposing Lassa fever outbreaks on the mean rainfall surface (Model 1 and the other two using non-linear discriminant analytical techniques. Model 2 selected variables in a step-wise inclusive fashion, and Model 3 used an information-theoretic approach in which many different random combinations of 10 variables were fitted to the Lassa fever data. Three combinations of absenceratiopresence clusters were used in each of Models 2 and 3, the 2 absenceratio1 presence cluster combination giving what appeared to be the best result. Model 1 showed that the recorded outbreaks of Lassa fever in human populations occurred in zones receiving between 1,500 and 3,000 mm rainfall annually. Rainfall, and to a much lesser extent temperature variables, were most strongly selected in both Models 2 and 3, and

    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

    Background There has been increased attention for the need to reduce stigma related to sexual behaviors among gay men and other men who have sex with men (MSM) as part of comprehensive human immunodeficiency virus (HIV) prevention and treatment programming. However, most studies focused on measuring and mitigating stigma have been in high-income settings, challenging the ability to characterize the transferability of these findings because of lack of consistent metrics across settings. Objective The objective of these analyses is to describe the prevalence of sexual behavior stigma in the United States, and to compare the prevalence of sexual behavior stigma between MSM in Southern and Western Africa and in the United States using consistent metrics. Methods The same 13 sexual behavior stigma items were administered in face-to-face interviews to 4285 MSM recruited in multiple studies from 2013 to 2016 from 7 Sub-Saharan African countries and to 2590 MSM from the 2015 American Men’s Internet Survey (AMIS), an anonymous Web-based behavioral survey. We limited the study sample to men who reported anal sex with a man at least once in the past 12 months and men who were aged 18 years and older. Unadjusted and adjusted prevalence ratios were used to compare the prevalence of stigma between groups. Results Within the United States, prevalence of sexual behavior stigma did not vary substantially by race/ethnicity or geographic region except in a few instances. Feeling afraid to seek health care, avoiding health care, feeling like police refused to protect, being blackmailed, and being raped were more commonly reported in rural versus urban settings in the United States (P<.05 for all). In the United States, West Africa, and Southern Africa, MSM reported verbal harassment as the most common form of stigma. Disclosure of same-sex practices to family members increased prevalence of reported stigma from family members within all geographic settings (P<.001 for all). After

    2012-01-01

    Qualitative nurse researchers are required to make deliberate and sometimes complex methodological decisions about their work. Methodology in qualitative research is a comprehensive approach in which theory (ideas) and method (doing) are brought into close alignment. It can be difficult, at times, to understand the concept of methodology. The purpose of this research column is to: (1) define qualitative methodology; (2) illuminate the relationship between epistemology, ontology and methodology; (3) explicate the connection between theory and method in qualitative research design; and 4) highlight relevant examples of methodological decisions made within cardiovascular nursing research. Although there is no "one set way" to do qualitative research, all qualitative researchers should account for the choices they make throughout the research process and articulate their methodological decision-making along the way.

    The purpose of this study was to examine coaches' preferences for continuing coaching education. The sample consisted of 122 male and 102 female coaches from the Gauteng Province of South Africa who were purposively recruited to participate in this study. The results of this study showed that the coaches wanted to learn more about motivational techniques, advanced instructional drills, advanced first aid, goal setting, character building and conditioning drills. The results further indicated that sport coaches would be more likely to continue their coaching education if they had a desire to coach at a high level, if topics were relevant and if courses were in line with league requirements and were available online. The practical implications of the findings for the development of coaching education programmes in South Africa were discussed.

    DNA of several spotted fever group rickettsiae was found in ticks in Israel. The findings include evidence for the existence of Rickettsia africae and Candidatus Rickettsia barbariae in ticks in Israel. The DNA of R. africae was detected in a Hyalomma detritum tick from a wild boar and DNA of C. Rickettsia barbariae was detected in Rhipicephalus turanicus and Rhipicephalus sanguineus collected from vegetation. The DNA of Rickettsia massiliae was found in Rh. sanguineus and Haemaphysalis erinacei, whereas DNA of Rickettsia sibirica mongolitimonae was detected in a Rhipicephalus (Boophilus) annulatus. Clinicians should be aware that diseases caused by a variety of rickettsiae previously thought to be present only in other countries outside of the Middle East may infect residents of Israel who have not necessarily traveled overseas. Furthermore, this study reveals again that the epidemiology of the spotted fever group rickettsiae may not only involve Rickettsia conorii but may include other rickettsiae.

    Full Text Available BACKGROUND: Tsetse flies of the Palpalis group are the main vectors of sleeping sickness in Africa. Insecticide impregnated targets are one of the most effective tools for control. However, the cost of these devices still represents a constraint to their wider use. The objective was therefore to improve the cost effectiveness of currently used devices. METHODOLOGY/PRINCIPAL FINDINGS: Experiments were performed on three tsetse species, namely Glossina palpalis gambiensis and G. tachinoides in Burkina Faso and G. p. palpalis in Côte d'Ivoire. The 1 × 1 m(2 black blue black target commonly used in W. Africa was used as the standard, and effects of changes in target size, shape, and the use of netting instead of black cloth were measured. Regarding overall target shape, we observed that horizontal targets (i.e. wider than they were high killed 1.6-5x more G. p. gambiensis and G. tachinoides than vertical ones (i.e. higher than they were wide (P < 0.001. For the three tsetse species including G. p. palpalis, catches were highly correlated with the size of the target. However, beyond the size of 0.75 m, there was no increase in catches. Replacing the black cloth of the target by netting was the most cost efficient for all three species. CONCLUSION/SIGNIFICANCE: Reducing the size of the current 1*1 m black-blue-black target to horizontal designs of around 50 cm and replacing black cloth by netting will improve cost effectiveness six-fold for both G. p. gambiensis and G. tachinoides. Studying the visual responses of tsetse to different designs of target has allowed us to design more cost-effective devices for the effective control of sleeping sickness and animal trypanosomiasis in Africa.

  6. Combining hydrology and mosquito population models to identify the drivers of Rift Valley fever emergence in semi-arid regions of West Africa.

    Directory of Open Access Journals (Sweden)

    Valérie Soti

    Full Text Available BACKGROUND: Rift Valley fever (RVF is a vector-borne viral zoonosis of increasing global importance. RVF virus (RVFV is transmitted either through exposure to infected animals or through bites from different species of infected mosquitoes, mainly of Aedes and Culex genera. These mosquitoes are very sensitive to environmental conditions, which may determine their presence, biology, and abundance. In East Africa, RVF outbreaks are known to be closely associated with heavy rainfall events, unlike in the semi-arid regions of West Africa where the drivers of RVF emergence remain poorly understood. The assumed importance of temporary ponds and rainfall temporal distribution therefore needs to be investigated. METHODOLOGY/PRINCIPAL FINDINGS: A hydrological model is combined with a mosquito population model to predict the abundance of the two main mosquito species (Aedes vexans and Culex poicilipes involved in RVFV transmission in Senegal. The study area is an agropastoral zone located in the Ferlo Valley, characterized by a dense network of temporary water ponds which constitute mosquito breeding sites. The hydrological model uses daily rainfall as input to simulate variations of pond surface areas. The mosquito population model is mechanistic, considers both aquatic and adult stages and is driven by pond dynamics. Once validated using hydrological and entomological field data, the model was used to simulate the abundance dynamics of the two mosquito species over a 43-year period (1961-2003. We analysed the predicted dynamics of mosquito populations with regards to the years of main outbreaks. The results showed that the main RVF outbreaks occurred during years with simultaneous high abundances of both species. CONCLUSION/SIGNIFICANCE: Our study provides for the first time a mechanistic insight on RVFV transmission in West Africa. It highlights the complementary roles of Aedes vexans and Culex poicilipes mosquitoes in virus transmission, and recommends

  8. Feasibility of onchocerciasis elimination with ivermectin treatment in endemic foci in Africa: first evidence from studies in Mali and Senegal.

    Directory of Open Access Journals (Sweden)

    Lamine Diawara

    Full Text Available BACKGROUND: Mass treatment with ivermectin is a proven strategy for controlling onchocerciasis as a public health problem, but it is not known if it can also interrupt transmission and eliminate the parasite in endemic foci in Africa where vectors are highly efficient. A longitudinal study was undertaken in three hyperendemic foci in Mali and Senegal with 15 to 17 years of annual or six-monthly ivermectin treatment in order to assess residual levels of infection and transmission and test whether ivermectin treatment could be safely stopped in the study areas. METHODOLOGY/PRINCIPAL FINDINGS: Skin snip surveys were undertaken in 126 villages, and 17,801 people were examined. The prevalence of microfilaridermia was <1% in all three foci. A total of 157,500 blackflies were collected and analyzed for the presence of Onchocerca volvulus larvae using a specific DNA probe, and vector infectivity rates were all below 0.5 infective flies per 1,000 flies. Except for a subsection of one focus, all infection and transmission indicators were below postulated thresholds for elimination. Treatment was therefore stopped in test areas of 5 to 8 villages in each focus. Evaluations 16 to 22 months after the last treatment in the test areas involved examination of 2,283 people using the skin snip method and a DEC patch test, and analysis of 123,000 black flies. No infected persons and no infected blackflies were detected in the test areas, and vector infectivity rates in other catching points were <0.2 infective flies per 1,000. CONCLUSION/SIGNIFICANCE: This study has provided the first empirical evidence that elimination of onchocerciasis with ivermectin treatment is feasible in some endemic foci in Africa. Although further studies are needed to determine to what extent these findings can be extrapolated to other endemic areas in Africa, the principle of elimination has been established. The African Programme for Onchocerciasis Control has adopted an additional

    Full Text Available Orientation: Independent financial advisers in South Africa can make a valuable contribution to the financial well-being of the country’s citizens and, through sound financial planning and education, assist them in becoming financially independent.Research purpose: The purpose of this study was to develop guidelines for creating customer loyalty towards independent financial advisers in South Africa.Motivation: To succeed, financial advisers need to build good relationships with clients and ensure they remain loyal to them in the long term.Research design, approach and method: A convenience non-probability sampling technique was applied, and altogether 262 self-administered questionnaires were completed and used in the analysis. Descriptive and standard multiple regression analysis and the one-way analysis of variance (ANOVA technique were used to test four hypotheses formulated for the study.Main findings: Relationship commitment must be established in a trustworthy environment, regardless of the type of province where the business is operated.Practical/managerial implications: In urban provinces (such as Gauteng both trusting relationships and commitment could lead to customer loyalty; in semi-urban provinces (such as North-West only the commitment variable might do so. Independent financial advisers in both provinces should explore additional factors that could foster customer loyalty.Contributions: The research findings of this study challenge the seminal work of Morgan and Hunt (1994 by establishing that in South Africa, the extent to which trust and commitment predicts customer loyalty is specific to both industrial and geographical location. This study further provides customer loyalty guidelines for independent financial advisers in South Africa.

    Full Text Available As organisations find themselves in an increasingly dynamic and competitive world they are seeking new strategies to ensure their competitive advantage and profitability. Logistics presents an area in which these organisations can improve customer service and reduce costs, and strategies in support thereof such as the outsourcing of logistics activities, should be considered. However, it is critical that logistics outsourcing is done diligently to avoid potential problems for the organisation and to achieve the best possible benefits. In South Africa little research has been done regarding current outsourcing practices of local manufacturers. In this article literature on international logistics outsourcing as well as research on some of the logistics outsourcing practices of South African manufacturers is discussed. The findings of a questionnaire survey of South African manufacturers provided information on their logistics outsourcing practices and problems. Prominent issues seem to include inadequate managerial involvement in the logistics outsourcing process, as well as insufficient time spent on many of the important aspects of the outsourcing agreement, the transitioning of resources and ongoing management of the outsourced relationship. It is concluded that a thorough outsourcing process should be followed in order to achieve the benefits of logistics outsourcing.

    Background Teenage pregnancy is a global social health concern especially because of the HIV and AIDS pandemic, sexually transmitted infections, high rate of termination of pregnancy (TOP), adolescents’ parenthood and decreased level of contraceptives. Aim To explore the views of teenagers on the TOP at Muyexe high school in a rural village of Mopani District, Limpopo Province. Setting Muyexe high school in a rural village of Mopani District, Limpopo Province, in South Africa. Methodology A qualitative method using explorative and descriptive designs was used to find in-depth description and understanding of teenagers’ views on TOP. The target population was girls aged 15–19 years at Muyexe high school in Mopani District. Non-probability, convenient sampling was used to select high school teenage girls who had undergone TOP for the study. Data were collected using individual self-report technique (interview). Tesch’s eight steps of qualitative data analysis were used. Measures to ensure trustworthiness and ethical considerations were observed. Results Two major themes were revealed: (1) Views of teenagers regarding TOP (poverty, relationship problems and single parenthood, negative impact on the teen’s life while attending school) and (2) teenager’s fears regarding pregnancy (stigma, fear of parents and friends, rape and incest and fear of giving birth). Conclusion Majority of participants had knowledge about TOP; some had experiences about TOP while others held inadequate knowledge. Recommendations were based on the findings by teaching dangers of TOP and various contraceptive methods to prevent unwanted pregnancies and TOP. PMID:27380849

    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.

It was assumed to apply to foods that primarily deliver available CHO, causing hyperglycaemia. Low-GI foods were classified as being digested and absorbed slowly and high-GI foods as being rapidly digested and absorbed, resulting in different glycaemic responses. Low-GI foods were found to induce benefits on certain risk factors for CVD and diabetes. Accordingly it has been proposed that GI classification of foods and drinks could be useful to help consumers make 'healthy food choices' within specific food groups. Classification of foods according to their impact on blood glucose responses requires a standardised way of measuring such responses. The present review discusses the most relevant methodological considerations and highlights specific recommendations regarding number of subjects, sex, subject status, inclusion and exclusion criteria, pre-test conditions, CHO test dose, blood sampling procedures, sampling times, test randomisation and calculation of glycaemic response area under the curve. All together, these technical recommendations will help to implement or reinforce measurement of GI in laboratories and help to ensure quality of results. Since there is current international interest in alternative ways of expressing glycaemic responses to foods, some of these methods are discussed.

  13. Engineering radioecology: Methodological considerations

    The term ``radioecology`` has been widely recognized in scientific and technical societies. At the same time, this scientific school (radioecology) does not have a precise/generally acknowledged structure, unified methodical basis, fixed subjects of investigation, etc. In other words, radioecology is a vast, important but rather amorphous conglomerate of various ideas, amalgamated mostly by their involvement in biospheric effects of ionizing radiation and some conceptual stereotypes. This paradox was acceptable up to a certain time. However, with the termination of the Cold War and because of remarkable political changes in the world, it has become possible to convert the problem of environmental restoration from the scientific sphere in particularly practical terms. Already the first steps clearly showed an imperfection of existing technologies, managerial and regulatory schemes; lack of qualified specialists, relevant methods and techniques; uncertainties in methodology of decision-making, etc. Thus, building up (or maybe, structuring) of special scientific and technological basis, which the authors call ``engineering radioecology``, seems to be an important task. In this paper they endeavored to substantiate the last thesis and to suggest some preliminary ideas concerning the subject matter of engineering radioecology.

  14. Cancer cytogenetics: methodology revisited.

    Wan, Thomas S K

    The Philadelphia chromosome was the first genetic abnormality discovered in cancer (in 1960), and it was found to be consistently associated with CML. The description of the Philadelphia chromosome ushered in a new era in the field of cancer cytogenetics. Accumulating genetic data have been shown to be intimately associated with the diagnosis and prognosis of neoplasms; thus, karyotyping is now considered a mandatory investigation for all newly diagnosed leukemias. The development of FISH in the 1980s overcame many of the drawbacks of assessing the genetic alterations in cancer cells by karyotyping. Karyotyping of cancer cells remains the gold standard since it provides a global analysis of the abnormalities in the entire genome of a single cell. However, subsequent methodological advances in molecular cytogenetics based on the principle of FISH that were initiated in the early 1990s have greatly enhanced the efficiency and accuracy of karyotype analysis by marrying conventional cytogenetics with molecular technologies. In this review, the development, current utilization, and technical pitfalls of both the conventional and molecular cytogenetics approaches used for cancer diagnosis over the past five decades will be discussed.

    In this article, I argue that the existing literature on qualitative methodologies tend to discuss analytical generalization at a relatively abstract and general theoretical level. It is, however, not particularly straightforward to “translate” such abstract epistemological principles into more...... operative methodological strategies for producing analytical generalizations in research practices. Thus, the aim of the article is to contribute to the discussions among qualitatively working researchers about generalizing by way of exemplifying some of the methodological practicalities in analytical...

  18. Towards the establishment and standardization of a veterinary antimicrobial resistance surveillance and monitoring programme in South Africa

    2004-11-01

    Full Text Available The objective of this study was to establish a repeatable, standardized laboratory procedure for monitoring the development of antimicrobial resistance in bacteria isolated from animals and food of animal origin in South Africa, with reagents prepared in-house. The emergence of resistance and the spread of resistant bacteria can be limited by implementing a veterinary antimicrobial drug policy, in which inter alia systematic monitoring and prudent use play essential roles. The bacteria included in this study represented three different categories, namely zoonotic bacteria (Salmonella, indicator bacteria (Escherichia coli, Enterococcus faecalis and Enterococcus faecium and veterinary pathogens (Mannheimia haemolytica. Thirty isolates of each species were collected with the aim of standardizing the laboratory methodology for a future national veterinary surveillance and monitoring programme. Susceptibility to ten selected antimicrobial drugs was determined by means of minimum inhibitory concentrations (MICs using the microdilution method. The method according to the National Committee for Clinical Laboratory Standards was used as the standard. Multi-well plates containing varying dilutions of antimicrobial drugs and prepared in-house for MIC determinations, yielded repeatable results. Storage of plates for 2 months at -70 oC did not influence results meaningfully. Within this limited sample of bacteria, MIC results did not indicate meaningful resistance against any of the ten selected antimicrobial drugs. The findings of the study will be used to establish a national veterinary antimicrobial resistance surveillance and monitoring programme in South Africa. To allow for international comparison of data, harmonisation of the surveillance and monitoring programme in accordance with global trends is encouraged. Ideally it should be combined with a programme monitoring the quantities of antimicrobial drugs used. The aim is to contribute to slowing down

  19. Validation of a remote sensing model to identify Simulium damnosum s.l. breeding sites in Sub-Saharan Africa.

    Directory of Open Access Journals (Sweden)

    Benjamin G Jacob

    Full Text Available BACKGROUND: Recently, most onchocerciasis control programs have begun to focus on elimination. Developing an effective elimination strategy relies upon accurately mapping the extent of endemic foci. In areas of Africa that suffer from a lack of infrastructure and/or political instability, developing such accurate maps has been difficult. Onchocerciasis foci are localized near breeding sites for the black fly vectors of the infection. The goal of this study was to conduct ground validation studies to evaluate the sensitivity and specificity of a remote sensing model developed to predict S. damnosum s.l. breeding sites. METHODOLOGY/PRINCIPAL FINDINGS: Remote sensing images from Togo were analyzed to identify areas containing signature characteristics of S. damnosum s.l. breeding habitat. All 30 sites with the spectral signature were found to contain S. damnosum larvae, while 0/52 other sites judged as likely to contain larvae were found to contain larvae. The model was then used to predict breeding sites in Northern Uganda. This area is hyper-endemic for onchocerciasis, but political instability had precluded mass distribution of ivermectin until 2009. Ground validation revealed that 23/25 sites with the signature contained S. damnosum larvae, while 8/10 sites examined lacking the signature were larvae free. Sites predicted to have larvae contained significantly more larvae than those that lacked the signature. CONCLUSIONS/SIGNIFICANCE: This study suggests that a signature extracted from remote sensing images may be used to predict the location of S. damnosum s.l. breeding sites with a high degree of accuracy. This method should be of assistance in predicting communities at risk for onchocerciasis in areas of Africa where ground-based epidemiological surveys are difficult to implement.

  20. Accuracy of serological testing for the diagnosis of prevalent neurocysticercosis in outpatients with epilepsy, Eastern Cape Province, South Africa.

    Full Text Available BACKGROUND: Few studies have estimated prevalence of neurocysticercosis (NCC among persons with epilepsy in sub-Saharan Africa. While the limitations of serological testing in identification of NCC are well known, the characteristics of persons who are misdiagnosed based on serology have not been explored. The first objective of this pilot study was to estimate the prevalence of NCC in epilepsy outpatients from an area of South Africa endemic for cysticercosis. The second objective was to estimate the accuracy of serological testing in detecting NCC in these outpatients and characterize sources of disagreement between serology and neuroimaging. METHODOLOGY/PRINCIPAL FINDINGS: All out-patients aged 5 or older attending the epilepsy clinic of St. Elizabeth's Hospital in Lusikisiki, Eastern Cape Province, between July 2004 and April 2005 were invited to participate. Epidemiological data were collected by local study staff using a standardized questionnaire. Blood samples were tested by ELISA for antibody and antigen for Taenia solium. Four randomly chosen, consenting participants were transported each week to Mthatha for brain CT scan. The proportion of persons with epilepsy attending St. Elizabeth clinic with CT-confirmed NCC was 37% (95% CI: 27%-48%. Using CT as the gold standard, the sensitivity and specificity of antibody testing for identifying NCC were 54.5% (36.4%-71.9% and 69.2% (52.4%-83.0%, respectively. Sensitivity improved to 78.6% (49.2%-95.3% for those with active lesions. Sensitivity and specificity of antigen testing were considerably poorer. Compared to false negatives, true positives more often had active lesions. False positives were more likely to keep pigs and to have seizure onset within the past year than were true negatives. CONCLUSIONS/SIGNIFICANCE: The prevalence of NCC in South African outpatients with epilepsy is similar to that observed in other countries where cysticercosis is prevalent. Errors in classification of NCC

    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.

  4. Experimental methodology for obtaining sound absorption coefficients

    Carlos A. Macía M

    2011-07-01

    Full Text Available Objective: the authors propose a new methodology for estimating sound absorption coefficients using genetic algorithms. Methodology: sound waves are generated and conducted along a rectangular silencer. The waves are then attenuated by the absorbing material covering the silencer’s walls. The attenuated sound pressure level is used in a genetic algorithm-based search to find the parameters of the proposed attenuation expressions that include geometric factors, the wavelength and the absorption coefficient. Results: a variety of adjusted mathematical models were found that make it possible to estimate the absorption coefficients based on the characteristics of a rectangular silencer used for measuring the attenuation of the noise that passes through it. Conclusions: this methodology makes it possible to obtain the absorption coefficients of new materials in a cheap and simple manner. Although these coefficients might be slightly different from those obtained through other methodologies, they provide solutions within the engineering accuracy ranges that are used for designing noise control systems.

    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 ...

    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.

This model-concept gives a three-phase assessment where the assessor tries to determine whether a specific place may be subject to assessment, to characterize the level of risk and to confirm or refute the findings of the first phase, collecting information and corrective measures, or to establish basic requirements for environment protection. Risk assessment methodology - American concept: The third methodological approach to environmental risk assessment is developed by the U.S. Agency for Environmental Protection, 'U.S. EPA'. This model primarily involves the implementation of environmental risk assessment under the conditions of anthropogenic impact on environment, without aiming at solving problems of natural environmental risks, although this methodology can be applied in this environment segment as well. The methodology gives a clear distinction between a scientific (phase of estimation and a non-scientific (planning part of assessment. The phases of estimation given by this model are: problem formulation, risk analysis and risk characterization. Conclusion: Concepts and methodologies of all three models-concepts of assessment are mostly reduced to a common goal: how to reduce existing or avoid potential risks. However, it should be noted that the implementation of appropriate management and ecological risk assessment does not guarantee that risks will be avoided or that the implementation of these processes will be successful.

    Although southern African Khoisan populations are often assumed to have remained largely isolated during prehistory, there is growing evidence for a migration of pastoralists from eastern Africa some 2,000 years ago, prior to the arrival of Bantu-speaking populations in southern Africa. Eastern Africa harbors distinctive lactase persistence (LP) alleles, and therefore LP alleles in southern African populations may be derived from this eastern African pastoralist migration. We sequenced the lactase enhancer region in 457 individuals from 18 Khoisan and seven Bantu-speaking groups from Botswana, Namibia, and Zambia and additionally genotyped four short tandem repeat (STR) loci that flank the lactase enhancer region. We found nine single-nucleotide polymorphisms, of which the most frequent is -14010(∗)C, which was previously found to be associated with LP in Kenya and Tanzania and to exhibit a strong signal of positive selection. This allele occurs in significantly higher frequency in pastoralist groups and in Khoe-speaking groups in our study, supporting the hypothesis of a migration of eastern African pastoralists that was primarily associated with Khoe speakers. Moreover, we find a signal of ongoing positive selection in all three pastoralist groups in our study, as well as (surprisingly) in two foraging groups.

    Full Text Available The purpose of this paper is to examine the requirements and successes of the New International Financial Architecture (NIFA on transparency and corporate governance from a global perspective with a special focus on Africa. In recent years, transparency, accountability and governance have become key topics with many countries around the world having adopted International Financial Reporting Standards (IFRS and corporate governance codes. The outcomes of these initiatives have been unconvincing. Desktop research was used to gather literature and data on compliance with corporate governance codes and International Financial Reporting Standards (IFRS and other NIFA requirements. This study established that in spite of many regional and global initiatives by the World Bank and relevant regulators, compliance with IFRS and governance in parts of Africa has yet to reach its best level and guidelines are not fully followed leading to opportunities for improvement and policy adjustments. This research has implications and uses for both global and local institutions and regulators concerned with economic stability and growth including the World Bank, central banks, capital markets and boards of companies and the government in general. The findings contribute to governance debates by providing additional perspectives from Africa on compliance with accounting standards and codes in a region where research and corporate governance and reporting issues are still confusing.

    Full Text Available Having spent some 50 years as an organic chemist with an interest in medicinal plant chemistry in South Africa it was relevant now to ask three questions, (1 when were natural products first utilised, (2 who were the people involved, and (3 what is the status quo? Based on older literature published in the South African Journal of Chemistry, information gleaned from attendance at innumerable chemistry conferences, and relevant literature in university archives, a great deal of information was gathered to answer the first two questions. For example, that the first veterinarian to treat cattle diseases caused by poisonous plants in the Eastern Cape was Dr Jotella Soga in the 1890s. Contributions from other prominent scientists such as Marais, Rindl, Rimington and Warren followed. From about 1940 to the 1990s, researchers concentrated mainly on the isolation of new compounds from local plants for which some indigenous knowledge was recorded. Foreign chemists also arrived and did a fair amount of ‘exploitation’ of natural products. Thus, the anti-cancer compound combretastatin was first isolated from the indigenous tree Combretum caffrum. Plant chemistry in South Africa has blossomed in the last decade, with many students from previously disadvantaged backgrounds, but with a keen interest in muti or medicinal chemistry, entering the field. Recent findings have rekindled the belief that a major development in natural products would at last emerge from Africa.

    The U.S. National Multi-Model Ensemble seasonal forecasting system is providing hindcast and real-time data streams to be used in assessing and improving seasonal predictive capacity. The NASA / USAID SERVIR project, which leverages satellite and modeling-based resources for environmental decision making in developing nations, is focusing on the evaluation of NMME forecasts specifically for use in impact modeling within hub regions including East Africa, the Hindu Kush-Himalayan (HKH) region and Mesoamerica. One of the participating models in NMME is the NASA Goddard Earth Observing System (GEOS5). This work will present an intercomparison of downscaling methods using the GEOS5 seasonal forecasts of temperature and precipitation over East Africa. The current seasonal forecasting system provides monthly averaged forecast anomalies. These anomalies must be spatially downscaled and temporally disaggregated for use in application modeling (e.g. hydrology, agriculture). There are several available downscaling methodologies that can be implemented to accomplish this goal. Selected methods include both a non-homogenous hidden Markov model and an analogue based approach. A particular emphasis will be placed on quantifying the ability of different methods to capture the intermittency of precipitation within both the short and long rain seasons. Further, the ability to capture spatial covariances will be assessed. Both probabilistic and deterministic skill measures will be evaluated over the hindcast period

    2015-10-01

    Full Text Available This chapter raises the question whether the current Afro-optimism can be considered a construction of a realistic image (situational and a narrative (process of Africa. It does so primarily by analyzing the 180 degree turn-around of the prestigious and influential magazine, The Economist, on Africa within the time span of a decade. In May 2000 the magazine claimed that Africa was a continent without hope, whereas in December 2011, Africa, according to The Economist, could be considered a continent of hopeful economies – where “the sun shines bright.” The chapter identifies and analyses the key editions of The Economist with reference to this complete turn-around on Africa. Three major pillars are identified in the analysis of The Economist in relation to the changes in Africa, (i the economic pillar (economic growth, investments and trade, (ii demographic change and (iii conflict, governance and democratization. Within each pillar a presentation of The Economist’s description and analysis is put forward to be followed by critical reflections by the author. The presentations and reflections also have reference to the analysis/empirical studies on Africa by key research institutions. In the concluding reflections of the chapter, the importance of culture for the understanding of African change - only mentioned in passing by The Economist - is put forward through concrete examples. The findings are that the Afro-optimist images/narrative put forward by The Economist and others do not hold together even if analysed from within its own frame. The analysis of The Economist and the Afro-optimist narrative also shows that it becomes fragile when confronted with an understanding of Africa that integrates cultural perspectives. The Afro-optimist narrative of The Economist has been constructed within a limited knowledge and timeframe that has restricted a deeper understanding of Africa. The conclusion of the chapter is that the way The Economist

    The book presents results of CLUVA (CLimate Change and Urban Vulnerability in Africa), a large European Commission funded research project (2010-2013). The project aimed to develop a better understanding of the risks and impacts of climate change related hazards to African cities, assess their vulnerability to these risks, and identify innovative strategies for planning and governance to increase their resilience. For the first time, a systematic and groundbreaking study of this kind was applied in an inter- and trans-disciplinary approach. CLUVA was unique in that it combined: a top-down perspective of climate change modeling with a bottom-up perspective of vulnerability assessment; quantitative approaches from engineering sciences and qualitative approaches of the social sciences; a novel multi-risk modeling methodology; strategic approaches to urban and green infrastructure planning with neighborhood perspectives of adaptation. The book broadly follows the approach taken in the CLUVA project. First, the co...

  15. History of blood transfusion in sub-saharan Africa.

    Schneider, William H

    2013-01-01

    The adequacy and safety of blood transfusion in sub-Saharan Africa is the subject of much concern, yet there have been very few studies of its history. An overview of that record finds that transfusions were first reported in Africa (sub-Saharan and excluding South Africa) in the early 1920s, and organized transfusion practices were established before the Second World War. Blood transfusion grew rapidly after 1945, along with the construction of new hospitals and expanded health services in Africa. Significant differences existed between colonial powers in the organization of transfusion services, but these converged after independence as their use continued to grow and decentralized and hospital-based practices were adopted. It was only after the oil crisis in the mid-1970s that health spending declined and the collection, testing, and transfusion of blood began to level off. Thus, when the AIDS crisis hit transfusion services, they were already struggling to meet the needs of patients. At this time, foreign assistance as well as the World Health Organization and the League of Red Cross Societies helped respond to both the immediate problem of testing blood, and for some countries, support existed for the broader reorganization of transfusion. Overall, the history shows that transfusion was adopted widely and quickly, limited mainly by the availability of knowledgeable doctors and hospital facilities. There was less resistance than expected by Africans to receive transfusions, and the record shows a remarkable flexibility in obtaining blood. The dangers of disease transmission were recognized from an early date but were balanced against the potential lifesaving benefits of transfusion.

  16. Emergent migration policy in a democratic South Africa.

    Kotze, H; Hill, L

    1997-01-01

    This article sets recent debates on migration policy in South Africa against broader historical realities that have shaped patterns of population movement on the subcontinent since the end of the nineteenth century. During the course of the last century, most forms of population movement were the result of disjointed regional economic development which can be traced to two epochal events at the end of the nineteenth century: the creation of the modern African state system and the discovery of mineral wealth in Southern Africa. Although regulation of migrant labor was a fundamental feature of the colonial period, it was only after 1950, when independent states began to define specific migration priorities, that states began to restrict significantly the flow of transnational labor. From this point notions such as internally displaced person, refugee and illegal immigrant become increasingly appropriate to the study of regional migration. Particular attention is given to current debate on the definition of refugee which forms part of a broader international debate. A number of South African writers have argued that, given the structural imbalances contained in the regional economy, the term "refugee" should be redefined to included economic migrants. This position is not shared by the South African Government, and an analysis of current policy and legislation demonstrates a growing tendency to restrict the influx of undocumented migrants. This is due, in part, to the recent political transition and the institutional compromises that it produced as well as the growth of negative sentiment towards illegal immigrants at both mass and elite levels, as demonstrated by two recent research findings. The article concludes with a summation of recent trends in South African migration policy and an evaluation of the ambiguous position that South Africa occupies within Southern Africa.

    Full Text Available BACKGROUND: Gestational diabetes mellitus (GDM is any degree of impaired glucose tolerance first recognised during pregnancy. Most women with GDM revert to normal glucose metabolism after delivery of their babies; however, they are at risk of developing type 2 diabetes later in life as are their offspring. Determining a country's GDM prevalence can assist with policy guidelines regarding GDM screening and management, and can highlight areas requiring research. This systematic review assesses GDM prevalence in Africa. METHODS AND FINDINGS: Three electronic databases were searched without language restrictions; PubMed, Scopus and the Cochrane Library. Thirty-one search terms were searched. Eligible articles defined GDM, stated what GDM screening approaches were employed and reported GDM prevalence. The reporting quality and risk of bias within each study was assessed. The PRISMA guidelines for systematic reviews were followed. The literature search identified 466 unique records. Sixty full text articles were reviewed of which 14 were included in the systematic review. One abstract, for which the full text article could not be obtained, was also included. Information regarding GDM classification, screening methods and prevalence was obtained for six African countries; Ethiopia (n = 1, Morocco (n = 1, Mozambique (n = 1, Nigeria (n = 6, South Africa (n= 4 and Tanzania (n = 1. Prevalence figures ranged from 0% (Tanzania to 13.9% (Nigeria with some studies focussing on women with GDM risk factors. Most studies utilised the two hour 75 g oral glucose tolerance test and applied the World Health Organization's diagnostic criteria. CONCLUSIONS: Six countries, equating to 11% of the African continent, were represented in this systematic review. This indicates how little is known about GDM in Africa and highlights the need for further research. Considering the increasing public health burden of obesity and type 2 diabetes, it is essential that the extent of

    Full Text Available Locally manufactured vehicles are destined (partly for the export market and thus, global competitiveness  is  important.  This  article  explores  the  challenges  facing  supply  chains  of locally manufactured vehicles in South Africa. The automotive industry is perceived to be the most advanced in supply chain management practices in South Africa. It has embraced technology and management practices that have transformed the manufacturing environment by using cutting-edge design and visualisation tools. However, the industry has fragilities and faces new and emerging supply chain challenges. A survey research design was employed and  the  data  was  collected  through  face-to-face  semi-structured  interview  questionnaires based on the purposive sampling technique. Data analysis and interpretation was based on descriptive  statistics  using  SPSS  software.  The  findings  revealed  that  there  are  challenges hindering  best  supply  chain  practices  of  local  vehicle  manufacturers.  The  research  also revealed that there is a perceived difference in supply chain challenges between the different manufacturers of different origins in South Africa. Asian manufacturers felt much stronger about the adequacy of their information systems compared to the European manufacturers. Asian  manufacturers  tended  to  agree  more  than  their  European  counterparts  that  labour problems were a challenge. European manufacturers, on the other hand, tended to agree more that rail transport is unreliable. This article contributes to the body of knowledge on supply chain practices in South Africa

    The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

    South Africa's 'quiet diplomacy' has been often used to reject the notion of South African leadership or regional hegemony in southern Africa. This article finds that this evaluation is founded on a misguided understanding of regional hegemony, which is based on conventional hegemony theories that are mostly derived from the global role of the United States after World War II. Alternatively, this article uses a concept of hegemony that, for example, takes into account the 'regionality' of Sou...

    Mission planning of organization is to select best strategy to complete its mission under the conditions of organizational states. A new methodology of generating and optimizing strategy of organizational course of actions (COA) was illuminated with a joint campaign. A process of generating and optimizing COA in military force was modeled. And enumerative and heuristic techniques were employed to search optimal strategy for the case of joint campaign. The complex between the two approaches to find best strategy was analyzed. The results from our case were given and compared with reality of joint campaign, on which deficiency of models was taken apart. The optimal COA, obtained from our new methodology under diverse campaigns conditions, is given and analyzed. Results from the simulation of the COA show that our approach to solve optimal strategy of organizational processes accords with traits of general landing campaign.

  13. South Atlantic continental margins of Africa: a comparison of the tectonic vs climate interplay on the evolution of equatorial west Africa and SW Africa margins

    CERN Document Server

    Seranne, M; Seranne, Michel; Anka, Zahie

    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 ...

    2014-10-01

    State-of-the-art neuroimaging techniques have accelerated progress in the study and understanding of sleep in humans. Neuroimaging studies in primary insomnia remain relatively few, considering the important prevalence of this disorder in the general population. This review examines the contribution of functional and structural neuroimaging to our current understanding of primary insomnia. Functional studies during sleep provided support for the hyperarousal theory of insomnia. Functional neuroimaging also revealed abnormalities in cognitive and emotional processing in primary insomnia. Results from structural studies suggest neuroanatomical alterations in primary insomnia, mostly in the hippocampus, anterior cingulate cortex and orbitofrontal cortex. However, these results are not well replicated across studies. A few magnetic resonance spectroscopy studies revealed abnormalities in neurotransmitter concentrations and bioenergetics in primary insomnia. The inconsistencies among neuroimaging findings on insomnia are likely due to clinical heterogeneity, differences in imaging and overall diversity of techniques and designs employed. Larger samples, replication, as well as innovative methodologies are necessary for the progression of this perplexing, yet promising area of research.

    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.

    Full Text Available South African managers today find themselves squeezed between juxtapositions, such as international competition and simultaneous skill development programmes to combat illiteracy. A second example is high unemployment and the concurrent shortage of IT specialists. Affirmative action has led to troublesome labour relations. HIV/AIDS has an enormous impact on business and must be managed. South African managers need to change their managerial approaches to cope with the increasing demands of this country. Managers must be aware of the realities facing them and know how to turn them into potential growth opportunities for their organisations and South Africa as a country.

    2011-12-01

    Full Text Available Purpose: The purpose of the article is to report on research that was completed to explore the concept of the bullwhip effect in supply chains and to illustrate empirically the presence of the bullwhip effect in automotive supply chains in South Africa. Problem Investigated: This article investigates the presence of the bullwhip effect - which was identified through an empirical study - and its causes and implications for supply chain management in the South African automotive component industry. Methodology: A literature study was conducted on the causes and implications of the bullwhip effect phenomenon. This was followed by an empirical study in the form of a survey among South African automotive component manufacturers. Descriptive and inferential statistics were used to determine the significant supply chain problems relating to the bullwhip effect in automotive supply chains. Findings and Implications: The results indicate that automotive component manufacturers are dependent on demand-forecasting information from their customers. They experience long lead times, fluctuating orders, cancellation of orders, excess and slow moving inventory and a lack of integration with suppliers and customers. There are also signs of relationship problems and a possible silo mentality. The mentioned results indicate the presence of the bullwhip effect in South African automotive supply chains. Since the bullwhip effect can have a major impact on organisations' costs, knowing where to invest effort and resources should be a high priority for supply chain managers. Value of the Research: Since the field of supply chain management is extremely dynamic, this article contributes to the body of knowledge and provides new insight into the bullwhip effect phenomenon. The results included in this article could assist parties in automotive supply chains to focus their attention on problems that might be within their control and if solved could lead to improved

  6. A Top to Bottom Lithospheric Study of Africa and Arabia

    Energy Technology Data Exchange (ETDEWEB)

    Pasyanos, M

    2006-10-31

    We study the lithospheric structure of Africa, Arabia and adjacent oceanic regions with fundamental-mode surface waves over a wide period range. Including short period group velocities allows us to examine shallower features than previous studies of the whole continent. In the process, we have developed a crustal thickness map of Africa. Main features include crustal thickness increases under the West African, Congo, and Kalahari cratons. We find crustal thinning under Mesozoic and Cenozoic rifts, including the Benue Trough, Red Sea, and East, Central, and West African rift systems. Crustal shear wave velocities are generally faster in oceanic regions and cratons, and slower in more recent crust and in active and formerly active orogenic regions. Deeper structure, related to the thickness of cratons and modern rifting, is generally consistent with previous work. Under cratons we find thick lithosphere and fast upper mantle velocities, while under rifts we find thinned lithosphere and slower upper mantle velocities. There are no consistent effects in areas classified as hotspots, indicating that there seem to be numerous origins for these features. Finally, it appears that the African Superswell has had a significantly different impact in the north and the south, indicating specifics of the feature (temperature, time of influence, etc.) to be dissimilar between the two regions. Factoring in other information, it is likely that the southern portion has been active in the past, but that shallow activity is currently limited to the northern portion of the superswell.

    Full Text Available This study presents a summary overview of the carbon balance of Sub-Saharan Africa (SSA by synthesizing the available data from national communications to UNFCCC and first results from the project CarboAfrica (net ecosystem productivity and emissions from fires, deforestation and forest degradation, by field and model estimates. According to these preliminary estimates the overall carbon balance of SSA varies from 0.43 Pg C y−1 (using in situ measurements for savanna NEP to a much higher sink of 2.53 Pg C y−1 (using model estimates for savanna NEP. UNFCCC estimates lead to a moderate carbon sink of 0.58 Pg C y−1. Excluding anthropogenic disturbance and intrinsic episodic events, the carbon uptake by forests (0.98 Pg C y−1 and savannas (from 1.38 to 3.48 Pg C y−1, depending on the used methodology are the main components of the SSA sink effect. Fires (0.72 Pg C y−1, deforestation (0.25 Pg C y−1 and forest degradation (0.77 Pg C y−1 are the main contributors to the SSA carbon emissions, while the agricultural sector contributes only with 0.12 Pg C y−1. Notably, the impact of forest degradation is higher than that caused by deforestation, and the SSA forest net carbon balance is close to equilibrium. Savannas play a major role in shaping the SSA carbon balance, due to their large areal extent, their fire regime, and their strong interannual NEP variability, but they are also a major uncertainty in the overall budget. This paper shows that Africa plays a key role in the global carbon cycle system and probably could have a potential for carbon sequestration higher than expected, even if still highly uncertain. Further investigations are needed, particularly to better address the role of savannas and tropical forests. The current CarboAfrica network of carbon measurements could provide future unique data sets for better estimating the

    During the last two decades, since digital technologies have become more sophisticated in acquiring real data and building faithful copies of them, their improvements have suggested interesting applications in the field of valorisation of Historical, Cultural and Artistic Heritage, with significant consequences in the share and widespread of knowledge. But although several technologies and methodologies for 3d digitization have recently been developed and improved, the lack of a standard procedure and the costs connected to their use still doesn't encourage the systematic digital acquisition of wide collections and heritage. The aim of this paper is to show the state of the art of a project whose aim is to provide a methodology and a procedure to create digital reproductions of artefacts for Institutions called to preserve, manage and enhance the fruition of archaeological finds inside museums or through digital exhibitions. Our project's aim is to find the most suitable procedure to digitally acquire archaeo logical artefacts that usually have small dimensions and have very complex and detailed surfaces. Within our methodology, particular attention has been paid to the use of widely shared and open-source visualization systems that enhance the involvement of the user by emphasizing three-dimensional characteristics of artefacts through virtual reality.

    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

    Gallstone ileus is a rare complication of recurrent gallstone cholecystitis. The classic radiographic triad of small bowel obstruction, pneumobilia and ectopic gallstone on abdominal plain radiograph is described with CT imaging. Because of the better resolution of CT compared with abdominal radiography and its recent accession to emergency use, radiologists should be aware of CT findings of gallstone ileus. We report a case in which gallstone ileus was initially diagnosed by CT. (orig.)

    This methodology serves to define a system for effective prioritization of efforts required to develop replacement technologies mandated by imposed and forecast legislation. The methodology used is a semi quantitative approach derived from quality function deployment techniques (QFD Matrix). QFD is a conceptual map that provides a method of transforming customer wants and needs into quantitative engineering terms. This methodology aims to weight the full environmental, cost, safety, reliability, and programmatic implications of replacement technology development to allow appropriate identification of viable candidates and programmatic alternatives.
